Abstract Introduction: Patients (pts) with Chronic Lymphocytic Leukemia (CLL) are known to have an increased risk of other cancers. Treatment with lenalidomide has been associated with an increased rate of solid tumors (ST) in pts with multiple myeloma (MM). However, the occurrence of ST in patients with CLL receiving therapy with lenalidomide remains unknown. Methods: We evaluated the development of ST in pts with CLL that received front-line treatment with lenalidomide as monotherapy or in combination with rituximab in clinical trials conducted at our institution. We report the characteristics and timing of ST, as well as patient outcome. All pts enrolled had indication for therapy according to the International Workshop on CLL guidelines and no history of malignancy for three years, with the exception of treated malignancy with indolent behavior such as prostate cancer that was treated with surgery or radiation therapy. Results: One-hundred twenty-one pts were enrolled in two consecutive phase II clinical trials of frontline therapy with lenalidomide (N = 61, 51%) or combination of lenalidomide and rituximab (N = 60, 49%). Baseline pts characteristics are shown in Table 1, median age was 66 yrs and 24% of patients were age 70 or older. At a median follow up after lenalidomide therapy of 41 months (range 1-102+), 7 (6%) pts developed a ST: renal cell carcinoma (RCC, 3 pts), localized breast cancer (LCIS and DCIS, 2 pts), pancreatic adenocarcinoma (1 pt) and colon adenocarcinoma (1 pt) (details are shown in Table 2). The median time interval between receiving lenalidomide-based therapy and the development of ST was 1.5 years (range 0-8.5). At the time of this report, 5 out of 7 pts with ST are alive and cancer-free. Two pts died: 12 months and 18 months after developing ST from progression of pancreatic adenocarcinoma and heart failure, respectively. Since pts with CLL have a high rate of non-melanoma skin neoplasms (NMSC), we also monitored patients for new diagnoses of skin cancers. Seven (6%) additional pts developed NMSC, 4 of these pts had prior history of NMSC. All cases of NMSC were superficial and did not require systemic therapy. Additionally, because of the high median age of this population, we reviewed prior history of malignancies. Eleven (9%) pts had history of ST [prostate cancer (N = 9), bladder cancer (N = 1), RCC (N = 1)]. Twenty-two pts (18%) had skin cancers (NMSC, (N = 21) and 1 pt had history of melanoma. None of them had received chemotherapy, two had radiation therapy [prostate cancer = 1, NMSC (basal cell carcinoma of the nose (1 pt)]. All ST were in remission before starting therapy with lenalidomide for more than 3 years as per the inclusion criteria. Conclusions: Seven cases of ST were observed in our population of 121 pts with CLL that received initial therapy with lenalidomide, after a median follow-up of 3.5 years. The most common neoplasm was RCC followed by in-situ breast cancer. In our limited experience the timing, number and type of malignancies do not appear to mirror what was seen in patients with MM. However, this comparison may be limited by the size of our patient population and length of follow-up. Our group reported the incidence of ST in patients treated with FCR. After a similar follow-up the incidence of second malignancies was similar (5.9%), but the type of malignancies was different, although NMSC remained the most common ST in both experiences. Reporting the incidence of other malignancies in patients with CLL enrolled in large studies, including those of novel targeted agents, will help understanding the expected incidence of ST and how novel treatments modulate such risk.

Abstract Background: It is well established that the incidence of skin cancers in patients with CLL are significantly elevated compared to age- and sex- matched controls. However, little is known about the characteristics of CLL patients who develop skin cancer. Herein, we evaluate the associations of CLL clinical and prognostic characteristics, along with UV radiation exposure, with risk of first skin cancer following CLL diagnosis. Methods: Newly diagnosed CLL patients from Minnesota, Iowa, and Wisconsin were enrolled in the Mayo Clinic case-control study from 2002-2015 and systematically followed in the Iowa/Mayo Lymphoma SPORE. Clinical and prognostic CLL data were obtained from the Mayo Clinic CLL database, and skin cancer clinical data were abstracted from medical records using a standard protocol. The CLL international prognostic index (CLL-IPI) was computed using a weighted average of five independent CLL prognostic factors (IGHV mutational status, serum b2-microglobulin, Rai stage, age, and FISH 17p deletion/TP53 status). Self-reported history of midday sun exposure at various ages (birth to age 12; 13 to 21 years; 22 to 40 years, and 41+ years) was obtained from a risk factor questionnaire. For each age, we asked the extent of mid-day sun as: practically no exposure (under 3 hours per week), little exposure (4-7 hours per week), moderate exposure (8 to 14 hours per week) and extensive exposure (15+ hours per week). Midday sun exposure was modeled as an ordinal covariate. To evaluate associations with risk of skin cancer following CLL diagnosis, we calculated time from date of CLL diagnosis to date of first skin cancer, death, or last known follow-up. We used Cox regression analysis to estimate hazard ratios (HRs) and 95% CIs. CLL treatment was considered a time-dependent covariate. Results: Among 846 CLL patients enrolled, the median age at diagnosis was 63 years (range 28-91), 68% were male, 7% had Rai stage III-IV at diagnosis. Based on the CLL-IPI, 42% were categorized as low risk, 33% as intermediate risk, and 25% as high or very-high risk. 109 CLL cases (13%) had one or more reported skin cancers at or prior to CLL diagnosis. Melanoma was observed in 19 (2%) cases and non-melanoma was in 90 (11%) cases. At a median follow-up of 7 years from CLL diagnosis, 165 patients (20%) had one or more skin cancers after CLL diagnosis. Among these patients, 49 had skin cancer before CLL diagnosis. The most frequent skin cancer was squamous cell carcinoma (59%), followed by basal cell (31%), melanoma (5%), and Merkel cell (1%). 552 (65%) of the 846 patients returned a questionnaire. Significant associations of clinical and prognostic characteristics with risk of first skin cancer were observed for age (HR=1.35 per 10 year increase, 95% CI=1.17-1.56, P<0.001), male sex (HR=1.38, 95% CI 0.98-1.96, p=0.07), prior history of skin cancer (HR=4.19, 95% CI=2.98-5.88, P<0.001), and CLL-IPI (HR=1.26, 95% CI= 1.03-1.54, P=0.026, after adjusting for age, sex, and prior skin cancer). Of note, the risk of first skin cancer in those CLL patients categorized as very high via CLL-IPI had 2.28 fold risk (95% CI 1.02-5.11). Midday sun exposures for each of the ages considered showed no evidence of association with risk of first skin cancer (all P>0.05). 50 CLL patients were treated prior to first skin cancer following CLL diagnosis; we observed no evidence of association between treatment and risk of first skin cancer (HR=1.44, 95% CI= 0.93-1.92, P=0.12). Conclusion: CLL patients who are at an increased risk of skin cancer following CLL diagnosis are those who either have had a prior history of skin cancer or a more aggressive CLL disease at diagnosis, according to CLL IPI. Routine skin cancer screening is currently recommended for CLL patients. Our data suggest that more frequent screening would be particularly important among patients with aggressive CLL and who have a prior history of skin cancer. Unexpectedly, we found no evidence of association of skin cancer risk with UV radiation following CLL diagnosis or with CLL treatment. Further investigation is needed to determine whether other factors increase the risk of skin cancer following CLL diagnosis.

Introduction: Incidence of heart failure (HF), specifically with preserved ejection fraction (HFpEF), is rising in the general population, yet is understudied. To provide a population-based estimate of HF in breast cancer (BC) survivors, we compared risk of HF in women with and without BC history in the Kaiser Permanente Northern California (KPNC) integrated health system. Methods: Data were extracted from KPNC electronic health records. All invasive BC cases diagnosed from 2005-2013 were identified and matched 1:5 with non-BC controls on birth year, race/ethnicity, and KPNC membership at BC diagnosis. Cox regression models assessed the hazard of HF by EF status: HFpEF (EF ≥ 45%), HF with reduced EF (HFrEF; EF < 45%), and unknown EF. Women with prior history of HF were excluded. Models were adjusted for factors known to affect BC risk or CVD and for prevalent CVD at BC diagnosis. We also examined case subgroups who received cardiotoxic chemotherapy, left-sided radiation therapy, and/or endocrine therapy, versus their controls. Results: A total of 14,804 women diagnosed with invasive BC and with no history of HF were identified and matched to 74,034 women without BC history. Women were on average 61 years at BC diagnosis and 65% white. Women with HFpEF were older and more likely to have hypertension (p<0.05). Among all cases vs. controls, there was increased risk of HFrEF (HR: 1.5, 95% CI: 1.18, 1.98) but not HFpEF or unknown EF (figure). Compared to their controls, women treated with chemotherapy were more than 3-times likely to develop HFrEF (HR: 3.26, 95% CI: 2.2, 4.8) and more than 1.5-times likely to develop HFpEF (HR=1.61, 95% CI: 1.15, 2.24). Women who received left-sided radiation therapy had nearly double the risk of developing HFrEF (HR=1.85, 95% CI: 1.20, 2.84). No associations were found among women who received endocrine therapy. Conclusions: Increased surveillance is warranted for women with BC receiving cardiotoxic chemotherapy for development of both HFrEF and HFpEF.

Background: Over the past 20 years, observational data from usual care clinical oncology settings has been leveraged to inform estimates of cancer treatment-associated benefits and risks among patients not treated on clinical trials. Increasing genomic testing to inform treatment decisions in usual care settings now meaningfully augments traditional observational data, positioning it to provide insights beyond clinical care into tumor biology. We studied patients with newly diagnosed multiple myeloma (MM), comparing cytogenetic test patterns according to history of prior malignancy. Methods: In this retrospective cohort study, we identified 2,380 patients from the COTA real-world database (RWD) who were newly diagnosed with MM in the years 2010-2018. The COTA RWD is a de-identified composite of both abstracted electronic health record and administrative data pertaining to patients receiving their cancer care at one of COTA's clinical oncology practice partners. Among these patients, 1769 (74%) had evidence of MM-associated cytogenetic testing with fluorescent in-situ hybridization (FISH) within the 120 days surrounding their date of diagnosis. The 1,769 patients form the analytic cohort. We compared patients' FISH results for t(4;14), deletion(17p), t(14;16), deletion(13), t(14;20), t(6;14), t(11;14), deletion (1p), and amplification(1q) according to their history of prior malignancy. Results: Within the cohort, 263 prior malignancies were identified in 241 patients (14%, 241/1,769). Two-hundred and twenty-one patients (92%) had one prior malignancy, 28 (7.9%) had two prior malignancies, and one (<1%) had four prior malignancies. The most common prior malignancies were prostate (n=50), breast (n=19), melanoma (n=14), skin (n=13), and cervix (n=6). Amplification of the long arm of chromosome one (amp(1q)) was noted in 31% of patients (75/241) with a prior malignancy vs. 24% of patients (370/1,528) without (chi2 test p=0.02). Overall 25% of patients had amp(1q). No other translocations, amplifications, deletions were associated with prior cancers. A non-parametric test for trend revealed a strong positive association between patients' malignancy count (range 0-4) and amp1q (p<0.01). MM patients with prior lymphomas and prior melanomas also had high rates of amp(1q), though these were not significantly different from patients without these prior malignancies. In a multivariable logistic regression model that adjusted for patient demographic attributes, other known potentially collinear MM poor prognostic factors (i.e., revised ISS stage, IgA sub-type, lambda light chains) and adjusted standard errors for clustering of patients within treatment settings, a history of prostate cancer remained clinically and statistically significantly positively associated with amp(1q) (OR 2.1, 95% CI: 1.9-2.2) as did history of two or more prior malignancies (OR 2.8, 95% CI: 2.3-3.3). Of note, amp(1q) was positively associated with IgA subtype (OR 1.5, 95% CI: 1.3-1.6) and the presence of lambda subtype (OR 1.3, 95%CI: 1.3-1.4). Conclusions: Using RWD, we found that newly diagnosed MM patients with histories of prostate cancer and those with two or more prior malignancies were more likely to have amp(1q), a poor prognostic marker in MM. Gains in 1q have previously been identified among patients with prostate and lymphoid cancers, but to our knowledge this is the first study to identify an association with a prior history of cancer, especially prostate cancer, and amp(1q) in MM. This relationship is worth further exploration of whether there is a common pathway associated with for example risk of prostate cancer and amp(1q) in MM. Clinical trials are less likely to answer this question as patients with prior malignancies are often excluded from enrollment. Overall, the results reported suggest that RWD is an efficient and comparatively inexpensive tool to support research in cancer biology through hypothesis generating and testing analyses of linked real-world phenotypic and genotypic data.

Abstract Abstract 3787 Background: The natural history of CML has been irrevocably changed since the advent of TKIs with pts living longer than they ever have. Some patients have a history of previous cancers by the time they are diagnosed with CML. These pts' long-term prognosis has never been previously described. Aims: To determine the effect of prior malignancy on patient outcome after diagnosis of CML. Methods: The primary objective was to determine outcome of pts with a previous diagnosis of malignancy (PM) vs a group without (nPM). Patients included in clinical trials of TKI as initial therapy for CML in chronic phase from July 2000 to January 2011 were reviewed. Results: Of the 471 CML pts treated with frontline TKIs 47 (10%) had a PM before their CML diagnosis and 5 (1%) pts PM status could not be obtained. The median age of the patients with a PM was 60 (30–84) compared to 46 (15–86) for those with no PM. There were no significant differences in clinical characteristics between PM and nPM patients. The median from diagnosis of a PM and a diagnosis of CML was 69 months (mo) (7 mo to 707 mo). The five most common PMs were: non-melanoma skin cancer in 14 (30%), breast cancer in 10 (21%), melanoma in 5 (11%), colorectal cancer in 5 (11%), and prostate cancer in 5 (11%). “Six pts (13%) had more than one PM and 2 of those 6 had 3 PM before the diagnosis of CML, the other 4 pts had 2 PM. The PMs were treated prior to the diagnosis of CML in the following ways: 17 (36%) pts received chemotherapy for their PM, 17 (36%) received radiotherapy, and 43 (91%) received surgery. At the time of CML diagnosis 3 (6%) pts had active cancer, while the remainder of the pts with a PM were thought to be in remission. Two (4%) pts were on active therapy for their prior cancer diagnosis at the time they started on CML therapy (Tamoxifen for breast cancer in both). After the diagnosis of CML, 6 (13%) pts had a recurrence of their PM including 2 pts with basal cell cancer, and 1 each with melanoma, breast cancer, prostate cancer, and lymphoma. These recurrent malignancies were treated as follows: 3 with radiation, 2 had surgery, and 2 with chemotherapy. Five of these 6 pts continued TKI while receiving therapy for PM. The median time between diagnosis of CML and relapse of PM was 18 months. Median remission of the PM was 151 months. Also, 6 (13%) pts had a new malignancy after CML diagnosis: 2 pts with squamous skin carcinoma, and 1 each with chronic lymphocytic leukemia, papillary thyroid carcinoma, mucoepidermoid carcinoma, and large B-cell lymphoma. Treatments for the new onset malignancy after the diagnosis of CML include: surgery (4), chemotherapy (2), radiation (1), and observation (1). The median time between diagnosis of CML and a new malignancy was 39 months. Six of the 47 pts are deceased: 2 died of their PM, 2 died secondary to treatment complications for their PM, 2 died of cardiovascular issues unrelated to a cancer diagnosis. None died of CML. Initial treatment for CML was imatinib 400mg in 4/47 (9%) PM and 69/419 (16%) nPM, imatinib 800mg in 15/47 (33%) PM and 189/419 (45%) nPM, dasatinib in 11/47 (24%) PM and 78/419 (19%) nPM, and nilotinib in 16/47 (35%) PM, and 83/419(20%) nPM. The outcome of pts with PM and nPM is presented in Table 1. There was no significant different in patient outcome between pts with PM and nPM. Conclusion: Pts with CML who have prior malignancies have the same excellent outcome as patients with no prior malignancies. In the few instances in which concomitant therapy for other malignancies was required during therapy with TKI this could be accomplished with no significant toxicity. Thus, the history of prior malignancy in a patient who develops CML should not affect the decision to treat with TKI.

Abstract Background: Tyrosine kinase inhibitors (TKIs) targeting BCR-ABL have revolutionized the prognosis of pts suffering from CML but these drugs are considered as non-definitively curative and current recommendation is to treat pts during their entire lifespan. However, prospective trials such as STIM, TWISTER and EUROSKI suggest that imatinib may be successfully stopped in pts with deep and sustained molecular responses. Here, we report on the feasibility of second generation TKIs discontinuation in the setting of the French STOP 2G-TKI study. Methods: Adult CP-CML pts on dasatinib or nilotinib first line or after imatinib without prior allogeneic transplantation or progression to advanced phase CML were proposed TKI discontinuation when presenting: (1) b2a2 or b3a2 BCR-ABL transcripts subtype, 2) TKI treatment duration for at least 36 months, (3) CMR4.5 achieved and maintained for at least 24 months. The primary objective was treatment-free survival without loss of major molecular response (MMR). After TKI discontinuation, BCR-ABL transcripts were monitored monthly during the first 12 months, every 3 months during the 2ndyear and every 3 to 6 months thereafter. Molecular relapse was defined by MMR loss on a single occasion and triggered TKI reintroduction. Data as of August 1, 2014 are reported in pts with at least 12 months of follow-up (n=52) and median follow-up was 32 months (12-56). Results: Median age was 60 years (34-81) and 61.5% of pts were female. Sokal risk group was low in 58%, intermediate in 23%, high in 13% and unknown in 6%. 2G-TKIs were given after imatinib intolerance in 67% of pts, suboptimal response or resistance to imatinib in 23% and upfront in 10%. Median duration of CML, TKI treatment, 2G-TKI treatment and CMR4.5 was 83 months (36-218), 78 months (36-136), 39 months (19-72) and 28 months (24-64), respectively. Twenty four pts lost MMR after a median time of 4 months (1-38) at last follow-up. Importantly, no loss of CHR or progression to advanced phase CML was observed. The 12- and 24-month probabilities of treatment-free survival without MMR loss were 61.4% (95% CI, 48.1-74.6) and 57% (95% CI, 43.3-70.6), respectively. The majority of relapses occurred within 6 months and in a landmark analysis, pts who were still in MMR without therapy at 6 months had 12- and 24-month probabilities of treatment-free survival without MMR loss of 91.2% (95% CI, 81.6-100) and 84.7% (95% CI, 72.2-97.1), respectively. All pts but 1 who lost MMR restarted 2G-TKI treatment and regained MMR after a median time of 3 months (1-8). Pts in MMR without any therapy (n=28) displayed varying patterns of spontaneous molecular response including stable CMR4.5 in 7 and fluctuations between CMR4.5 and MR4.5, CMR4.5 and MR4, CMR4.5 and MMR in 9, 4 and 4 pts, respectively. Gender, age, prior interferon exposure, 2G-TKI type, treatment duration and duration of CMR4.5 were not found to have any impact on outcome. By contrast, prior history of suboptimal response or resistance to imatinib was associated with a significantly lower chance of successful treatment discontinuation, with a 12-month probability of treatment-free survival without MMR loss of 41.7% (95% CI; 13.8%-69.6%), compared to 67.3% (95% CI, 52.6%-81.8%) in other patients (p=0.04). Conclusions: 2G-TKI could be safely and successfully discontinued in CP-CML pts with long-lasting undetectable BCR-ABL transcripts, especially in those without prior history of suboptimal response or resistance. Most of molecular relapses had an early onset and all were sensitive to 2G-TKI resumption. The recurrence of low levels of detectable residual disease below MMR after 2G-TKI withdrawal did not automatically herald CML relapse and did not preclude the possibility to remain treatment-free.

Abstract Background: Increased rates of SPM have been observed as newer cancer treatments have improved survival over the past 2 decades (Fraumeni et al. NCI, 2006). Higher incidence of specific types of hematologic SPM following MM, especially acute myeloid leukemia and myelodysplastic syndromes, have been reported relative to the general population (Dores et al. NCI, 2006; Mailankody et al. Blood, 2011; Ravazi et al. Blood, 2011; Landgren and Mailankody. Leukemia, 2014). A complex interplay between myeloma-, host-, environmental-, and treatment-related factors likely contributes to the increased incidence of SPM in MM. Connect MM is the first and largest prospective, observational, US-based, multicenter registry designed to characterize patients (pts), treatment patterns, and outcomes in newly diagnosed MM (NDMM) pts. Methods: Between September 2009 and November 2012,a total of 1493 NDMM pts were enrolled from 234 US sites within 2 mos of the first diagnosis of MM. Patient data were collected at baseline and each subsequent quarter using a standardized form. Invasive SPM included hematologic and solid tumor second cancers and non-invasive SPM were defined as non-melanoma skin cancers (NMSC). SPM incidence and incidence rate (IR; number of pts with SPM per 100 patient-yrs [PY]) were calculated for all pts and by exposure to specific treatments, including lenalidomide (LEN). PYs were calculated as the observation period from the start of treatment until the detection of the first reported SPM (per category), death, or end of follow-up (pt lost or data cutoff). Results: As of Dec 10, 2013, SPM data were available for 1493 NDMM pts. The median age was 67 yrs (range, 24-94 yrs), 82% of patients were white and 57% were male. Median follow-up was 29.0 mos (0-49 mos). The median OS of treated pts was 44.4 mos. Fifty pts did not receive treatment and had no SPM reported. A total of 74 of the 1443 treated pts (5.1%) reported SPM. Invasive SPM were observed in 51 pts (3.5%): 37 pts (2.6%) with solid tumors and 14 pts (1.0%) with hematologic SPM. Lung/bronchus and myelodysplastic syndromes were the most frequently reported solid tumor and hematologic SPM respectively. NMSC were reported for 26 pts (1.8%). 3 pts had both an invasive SPM and NMSC. The IRs for invasive, hematologic, and solid tumor SPM by LEN exposure are listed in Table 1. By multivariate analysis, the only significant risk factor for the occurrence of SPM was prior history of invasive malignancy. Demographics (including age, ethnicity, race, and gender), International Staging System stage, family history of myeloma or other cancers, history of smoldering MM or monoclonal gammopathy of unknown significance, or prior radiation therapy were not associated with the occurrence of SPM. Conclusions: This analysis shows that there was no increased risk of invasive SPM in this disease-specific registry of pts with NDMM. The risk of SPM for LEN exposed pts was not greater than that for pts not exposed to LEN. In addition, multivariate analysis indicated the only significant risk factor for SPM was prior history of invasive malignancy. As additional agents are approved for the treatment of MM and the length of pt survival increases, longer prospective observation with expanded enrollment on the registry will better characterize the occurrence of SPM in this pt population. Correlations with risk factors including age, pre-existing MDS, risk status, as well as type and duration of therapy will continue to be investigated. Table 1.

Introduction: Individuals with chronic lymphocytic leukemia (CLL) are often immunosuppressed and at increased risk of infection and secondary malignancies. The primary aim of this study was to determine the incidence of skin cancer amongst the CLL population at Kingston Health Sciences Centre (KHSC), Ontario, Canada. Secondly, we sought to identify the risk factors associated with the development of skin cancer in CLL patients. Methods: Consecutive patients seen at KHSC with a diagnosis of CLL between 2014 January 1 and 2019 December 31 formed the primary study cohort. KHSC serves a region of ~ 550,000 including a high proportion of older individuals and those living in rural areas. Approval was provided by Queen's University Research Ethics Board. Four independent reviewers conducted retrospective electronic chart review, initially in duplicate with review of any areas of discrepancy to ensure a standardized approach. Data collected included age, sex, CLL date of diagnosis, stage, genetics and treatment; histological diagnoses of other cancers (skin and other), smoking status (ever/never) and date of last follow up or death. The primary outcome was the development of the first skin cancer (squamous cell carcinoma, basal cell carcinoma, melanoma, or sarcoma) confirmed via pathology reports that are available in our local institution. All statistical analysis was performed using SAS Enterprise v. 7.15. Categorical variables were compared using chi-square or Fisher exact tests, medians using Wilcoxon and Mann-Whitney tests, and continuous variables using t-tests. Risk factors for development of skin cancer were assessed using multivarable Cox-proportional hazard models. Results: Of the total cohort of 377 individuals with CLL, 251 (67%) were male. Median age at diagnosis of CLL was 65 years (range 36 - 93 years of age). Median follow-up from the time of CLL diagnosis was 6.5 years (range 0.27 - 30.98). Of these, 80 individuals (21.2%) developed at least one skin cancer after their diagnosis of CLL, with an age-adjusted incidence of 16.96/1000 patient years (95% CI 12.5 - 23). Among the 297 who did not develop skin cancer post-CLL diagnosis, 13 individuals who had documented skin cancer pre-CLL diagnosis only, are included in the non-skin cancer group (Figure 1). Females had a lower incidence of skin cancer compared with males (63 males versus 17 females, p=0.009). There was no difference between the groups based on Rai stage at diagnosis, smoking history, or IGHV /p53 status. Individuals treated with ibrutinib had a lower incidence of skin cancer (3 versus 49, p=0.002). Development of skin cancer was associated with development of other invasive tumours including CLL transformation (p=0.001) (Table 1). Conclusion: Limitations of this study include its small size, and single institution setting. Our data likely reflect a conservative estimate as skin cancers may be diagnosed outside of the institution, and not all CLL is treated at tertiary care centres. Consistent with other studies we found that males with CLL are at increased risk of developing skin cancer, as compared to females. Individuals with CLL and skin cancer were more likely to develop another malignancy or Richter's transformation. The finding of lower incidence of skin cancer with ibrutinib treatment is novel; further investigation in larger populations is needed to determine if it may offer a protective effect.

Introduction Ibrutinib is an oral irreversible inhibitor of Bruton's tyrosine kinase for treatment of chronic lymphocytic leukemia (CLL). Ibrutinib has demonstrated superior efficacy for patients with TP53 aberration or relapsed/refractory (R/R) CLL; and more recently superior progression free survival (PFS) has been demonstrated compared to chemoimmunotherapy as first line therapy. However, knowledge about the outcomes and adverse events (AE) upon ibrutinib among patients at a population-based level are still limited. The aim of the here presented study is to explore outcomes of ibrutinib treatment in a population-based cohort of patients with CLL treated with ibrutinib in Denmark. Methods In this retrospective study, patients from 8 hospitals in Denmark, who were diagnosed with CLL and treated with ibrutinib from April 2014 until February 2019 were included. Medical records were retrospectively reviewed to obtain information. Patients receiving ibrutinib within clinical trials were excluded. Overall survival (OS) was defined as time from ibrutinib start to death from any cause while PFS was defined as time from ibrutinib start to progression or death from any cause. PFS and OS were analyzed with the Kaplan-Meier method while cumulative incidence was calculated with the Aalen-Johansen estimator. Results In total, 205 patients with CLL receiving ibrutinib treatment were identified from hospital records and registries. The median follow-up was 21.4 months (IQR, 11.9-32.8) and the median time on ibrutinib was 16.8 months (IQR, 6.0-28.1). The median age at treatment initiation was 72.8 years (IQR, 65.7-77.8), 128 (62.4%) were male, and 111 (63.4%) were Binet stage B/C at treatment initiation out of 175 with available information regarding clinical stage. Thirty-nine (19.0%) received ibrutinib as first-line, and 166 for R/R CLL with a median of 2 (range, 1-8) prior treatment regimens. Information on TP53 aberration was available for 149 and regarding IGHV mutation for 147 patients, 111 (74.5%) had TP53 aberration and 107 (72.8%) were IGHV unmutated. Eighty-six patients (42.0%) discontinued ibrutinib during follow-up with a median time until discontinuation of 9.3 months (IQR, 3.0-23.2). Forty-seven (54.7%) discontinued due to AEs, 19 (22.1%) due to progression (12 had progression of CLL and 7 had Richter's transformation) while the remaining 20 (23.2%) discontinued due to other reasons. The estimated cumulative incidence of discontinuation at 12 months was 24.8% (95% CI: 18.6-30.9). The estimated OS after 12 and 24 months was 88.8% (95%CI: 84.3-93.3) and 76.8% (95%CI: 70.4-83.2) and the estimated PFS after 12 and 24 months was 87.3% (95%CI: 82.5-92.1) and 72.4% (95%CI: 65.5-79.2). One hundred and eighty-eight (91.7%) experienced at least one AE, among these 45 (23.9%) experienced a grade 3+. The most common AEs were hemorrhage (tendency to bruise, epistaxis etc.) which occurred in 86 (42.0%) of all and musculoskeletal and connective tissue disorders (arthralgia, myalgia etc.) which occurred in 82 (40.0%). Thirty-one (15.1%) patients experienced atrial fibrillation while on ibrutinib and 14 (6.8%) developed hypertension. One hundred and thirty-seven patients (66.8%) had at least one infection and among these 80 (58.4%) were hospitalized with an infection. The most common infections were lower respiratory tract infections and urinary tract infections that occurred for 88 (42.9%) and 41 (20.0%). The estimated cumulative incidence for any infection was 58.9% (95%CI: 52.0-65.9) at 12 months. Conclusion This is the first study describing outcomes for a population-based cohort of CLL patients treated with ibrutinib in Denmark. Real-world studies are warranted, to confirm the results from clinical trials. In this study, patients appear to have comparable OS and types of AE compared with the RESONATE trial. Differences in frequency of AEs compared to the clinical trial may reflect the focus of clinicians in routine practice. Discontinuation in this cohort was higher compared to clinical trials but comparable to previously reported real-world studies. While ibrutinib can be safely managed in routine clinical practice, this study demonstrates that a quarter of patients discontinue treatment due to mainly AEs. Further patient training and information, and in some instances personalized treatment with other targeted agents based on adverse event profile, may improve treatment adherence.

New Paradigm

Abstract The article presents scientific evidence that confirms the new paradigm that  “early” diagnosis is not always beneficial, and that screening and early diagnosis can do more harm than good. As a result, of screening, in a number of cases, lesions are diagnosed that, although have histological patterns of cancer, are often clinically insignificant, indolent i.e. overdiagnosis takes place. Such lesions primarily include latent cancers of the prostate and thyroid gland. An increase in the incidence of certain types of cancers in the United States and other developed countries, as a result, of the introduction of PSA screening, mammography, ultrasound examination of the neck and other highly sensitive diagnostic methods, with stable or decreasing mortality, is a sign of overdiagnosis. In Russia, there is also a marked increase in the incidence of cancer of the prostate, breast, thyroid, kidney and melanoma, while mortality from these forms of cancer is stable or decreasing. The increase in the incidence of all malignant formations in Russian, as in American men, is determined by the increase in the incidence of prostate cancer. In randomized clinical trials of the efficacy of screening for prostate and breast cancer, an excess of the detected cases of cancer in the screening group compared with the control group indicates overdiagnosis. With an increase in follow-up (10-15 years), the number of excess cases in the screening group decreases. However, in some studies even after 10-15 years of follow-up, the excess of cancer cases in the screening group persisted, i.e. overdiagnosis was confirmed. Thus, the problem of overdiagnosis is also relevant to controlled clinical trials, despite a well-verified protocol and strict adherence to it. The danger of overdiagnosis in real life, daily practice, and especially with opportunistic screening, which, by definition, is carried out without quality control, is much higher. Overdiagnosis often leads to unnecessary, sometimes excessive treatment and a deterioration in the quality of life of patients who are not cancer patients. Refusal of aggressive therapy and active follow-up should be the method of choice for the management of patients with asymptomatic neoplasms identified at the screening. Such tactics will avoid unnecessary and excessive interventions, which, in turn, will prevent a deterioration in the quality of life of patients and, in addition, will reduce the cost of treatment. Key words: overdiagnosis, screening, early diagnosis, trends in incidence and mortality, prostate cancer, breast cancer, thyroid cancer

Abstract Abstract 4610 Introduction: Infections are a major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL). Up to 50% of patients with CLL will develop infectious complications during the course of their disease, and 30–50% of all deaths from CLL are attributed to infections and infectious complications. The risk of infection in CLL is related to immune deficiencies associated with the primary disease process, as well as immunosuppression secondary to treatment. Available research on infectious complications of CLL has focused on patients in clinical trials receiving chemotherapy. Little is known about the natural history of infection in community dwelling patients with newly diagnosed CLL. Method: To explore the natural history of infection in a local, community dwelling cohort of patients diagnosed with CLL, we used the Mayo Clinic CLL database to identify all patients with newly diagnosed CLL seen in the Mayo Clinic Division of Hematology after January 1, 1999 and who resided within 50 mi of Mayo Clinic (Rochester, MN). All patient hospitalizations were reviewed to document infection including cross-referencing with the electronic Mayo Clinic infection database which includes all culture and serology results obtained from hospitalized Mayo Clinic patients. Patients who had positive blood, sputum, cerebrospinal fluid, pleural fluid, or paracentesis fluid culture results were identified. Patients whose cultures were negative were considered to have culture negative infection. Serologies and viral assays (e.g. CMV viral load) were also reviewed to identify infections. Results: In May 2010, there were 2022 patients in the Mayo Clinic CLL Database with the diagnosis of CLL/SLL made between Jan 1999 – Dec 2009. Of these, 336 (17%) patients resided within a 50 mi radius of Mayo Clinic and were considered non-referred, community-based CLL patients. Median age at diagnosis for these 336 patients was 69 yrs (range 27–97) and most had early stage CLL (57% stage 0; 34% stage I-II). With respect to prognostic markers, 206 (70%) patients were CD38 negative, 125 (64%) ZAP-70 negative, 85 (53%) IgVH mutated, and 101 (63%) had either no abnormality or 13q14- as a sole abnormality on FISH analysis. Consistent with being a community dwelling cohort, ~90% (152/165) of patients had co-morbid health problems and ~50% (86/165) had a major comorbidity (e.g. coronary artery disease, cerebral vascular disease, CHF, diabetes, COPD, other malignancy). Although ~17% (43/249) of patients had gamma-globulin levels below the reference range at diagnosis, only 2% (6/249) had an IgG level <500 mg/dL. Median follow-up for all patients was 49 months (range 0–121) and 104 (31%) patients progressed to require treatment for CLL. Although 222 (66%) patients required hospitalization during follow-up, only 38 (11.3%) were hospitalized with infection. Collectively, these 38 patients were hospitalized for infection 139 times (median 2 hospitalizations for infection per patient). Among these 38 patients, 13 had no organism identified on cultures (culture negative infection) while the remaining 25 (66%) had an organism identified during at least hospitalization for infection. Of the 38 patients hospitalized with infection, 18/38 (47%) had a gram positive organism (8 strep pneumonia, 11 staphylococcus Aureus, 2 nocardia), 11/38 (29%) had a gram negative organism (3 E.Coli, 4 Pseudomonas, 4 Hemophilus influenzae), 5/38 (13%) a mycobacterial infection (4 MAC, 1 M. gordonae), 15/38 (40%) a cytomegalovirus infection, 19/38 (50%), cryptococcus and/or cryptosporidium (18 cryptococcus AG, 4 cryptosporidium), and 12/38 (32%) a filamentous fungi infections (12 aspergillous). In aggregate, hospitalization for an opportunistic infection (e.g. cytomegalovirus, cryptococcus, filamentous fungi, myocobacteria, pneumocystis) occurred in 26/336 (8%) CLL patients during follow-up. Being male (OR 2.7; p=0.02), ZAP-70+ (OR 3.9; p=0.004), IGHV unmutated (OR 5.5; p=0.002), and receiving treatment (OR 4.7, p<0.001; Figure) were associated with increased risk of hospitalization for infection. Conclusions: Approximately 8% of newly diagnosed, community dwelling CLL patients will require hospitalization for opportunistic infection at some point during the course of their disease. Gender, disease factors (e.g. ZAP-70, IGHV status), and treatment characteristics are associated with infection risk.
