Resectable Colonic Carcinoma—A Five Year Experience

Clinical characteristics, mode of presentation and pathological features of resectable carcinoma of the colon have been studied in 224 cases presenting between January 1971 and December 1975. Minimum length of follow-up is five years and is complete. Forty-three per cent of patients survived five years or more, only 23 per cent of tumours being early in histological terms. The conventional high risk groups contributed little to the total and their active surveillance will not significantly improve the overall statistics.

Abstract Background: Multiple myeloma (MM) is a heterogeneous disease with very divergent outcomes that are dictated in a large part by specific cytogenetic abnormalities, as well as other prognostic factors such as the proliferative rate of marrow plasma cells. Prognostic systems incorporating these factors have shown clinical utility in identifying high-risk patients, and are increasingly being utilized for treatment decision-making. However, the prognostic relevance of these factors may change with the application of novel therapies. The objective of this study was to determine the impact of risk-stratification (incorporating plasma cell metaphase cytogenetics, interphase fluorescent in-situ hybridization (FISH) and the slide-based plasma cell labeling index (PCLI)) in a cohort of patients with newly diagnosed MM treated initially with lenalidomide + dexamethasone (Rev-Dex). Methods: From March 2004 to November 2007, 100 consecutive patients treated with Rev (25mg/day) on days 1 through 21 of a 4-week cycle in combination with dexamethasone as initial therapy for newly diagnosed myeloma, were identified. High-risk MM was defined as presence of any one or more of the following: hypodiploidy, monoallelic loss of chromosome 13 or its long arm (by metaphase cytogenetics only), deletion of p53 (locus 17p13) or PCLI ≥ 3% or immunoglobulin heavy chain (IgH) translocations, t(4;14) (p16.3;q32) or t(14;16)(q32;q23) on FISH. PFS and OS survival estimates were created using the Kaplan Meier method, and compared by log-rank tests. Results: The median estimated follow-up of the entire cohort (N=100) was 36 months. The median PFS was 31 months; the median OS has not been reached. The 2- and 3-year OS estimates were 93% and 83%, respectively. 16% patients were deemed high-risk by at least one of the 3 tests (cytogenetics, FISH or PCLI). Response rates (PR or better) were 81% versus 89% in the high-risk and standard risk groups, respectively, P=NS; corresponding values for CR plus VGPR rates were 38% and 45% respectively. The median PFS was 18.5 months in high-risk patients compared to 37 months in the standard-risk patients (n=84), P<0.001(Figure). Corresponding values for TTP were 18.5 months and 36.5 months, respectively, P=<0.001. OS was not statistically significant between the two groups; 92% 2-year OS was noted in both the groups. Overall, 95 patients had at least one of the 3 tests to determine risk, while 55 patients could be adequately stratified based on the availability of all the 3 tests, or at least one test result that led to their inclusion in the high-risk category. The significant difference in PFS persisted even when the analysis was restricted to the 55 patients classified using this stringent criterion; 18.5 months vs. 36.5 months in the high-risk and standard- risk groups respectively; P<0.001. In a separate analysis, patients who underwent SCT before the disease progression were censored on the date of SCT to negate its effect, and PFS was still inferior in the high-risk group (p=0.002). Conclusion: The TTP and PFS of high-risk MM patients are inferior to that of the standard-risk patients treated with Rev-Dex, indicating that the current genetic and proliferation-based risk-stratification model remains prognostic with novel therapy. However, the TTP, PFS, and OS obtained in high-risk patients treated with Rev-Dex in this study is comparable to overall results in all myeloma patients reported in recent phase III trials. In addition, no significant impact of high-risk features on OS is apparent so far. Longer follow-up is needed to determine the impact of risk stratification on the OS of patients treated with Rev-Dex. Figure Figure

Abstract WM is a disease of the elderly with a protracted course in many patients. There are limited data which indicate that several WM patients die due to causes which are not directly related to their underlying malignancy. However, the realization and the estimation of the contribution of unrelated mortality in WM are important for the design of treatment strategy in patients of advanced age. To our knowledge there are no such data published for WM patients. Thus, we analyzed the outcomes of 408 patients with symptomatic WM who received therapy within the centers of the Greek Myeloma Study Group in order to assess disease related survival. In this analysis unrelated death was considered to be a competing risk event. Causes of death other than WM, treatment toxicity or myelodysplasia/transformation were considered as unrelated deaths. Median age of patients was 68 (28-92) years; 21% were >75 years and 9% were ≤50 years of age. Patients who started therapy after 2000 were older (median age 70 vs. 65 years before 2000, p<0.001) while 25% were >75 years (vs. 13% before 2000). In terms of ISSWM stage, more patients had high and intermediate risk disease after 2000 (41% & 42% vs. 25.5% & 38% before 2000, p<0.001), probably due to increased proportions of older patients in the recent era. Only 4% of patients before 2000 vs. 79% after 2000 received primary therapy with rituximab; however, similar rates of at least 50% IgM reduction were recorded (63% vs. 58%, p=0.361). Median follow up for all patients was 5.5 years (9 years in the pre-2000 and 4.5 years in the post-2000 group) and 52% of patients have died (77% in the group before 2000 and 40% in the group after 2000). However, 23% of deaths were considered unrelated to WM. Thus, 5-year and 8-year overall survival (OS) was 70% and 54% respectively, with a median OS of all patients of 8.8 years. When we performed survival analysis with unrelated deaths as competing risk, then 5-year risk of WM-related death was 21.4% (95% CI 17-26%) and of unrelated death was 7.6% (95% CI 5-10.5%), while 8-year WM-related death rate was 32% (95% CI 27-37%) and unrelated death 11.5% (95% CI 8-15%). Because older patients are at higher risk of unrelated deaths we performed an age-specific analysis. The median survival of patients >75 years was 5.3 vs. 9.7 years for patients ≤75 years (p<0.001). However, for patients >75 years, the 5-year death rate due to WM was 22% (95% CI 13-32%) vs. 21% (95% CI 16-26%) for patients ≤75 years (p=0.193), while the 5-year unrelated death rate was 17% (95% CI 10-27%) and 5.1% (3-8%), respectively (p<0.001). Thus, in patients with advanced age (>75 years) >40% of deaths are unrelated to WM, while WM-specific death rates were similar for patients >75 or ≤75 years. In patients ≤50 years there were no WM-unrelated deaths. We then evaluated the prognostic significance of IPSSWM, which discriminated 3 groups with 5-year overall survival of 86%, 68% and 51% for low, intermediate and high risk groups, respectively (p<0.001). However, because intermediate and high risk IPSS groups are enriched for older patients we performed the analysis with unrelated deaths as competing event. The 5-year WM-specific death rate was 10%, 19% and 27% for the three risk groups (p=0.035), while the 5-year unrelated death rate was 1.5%, 5% and 14%, respectively (p=0.003). The median OS for patients who started therapy before and after 2000 was similar (9 vs. 8.1 years, respectively, p=0.474). However, when we performed competing event survival analysis, then the 5-year WM-related death rate was 21% for both groups, but the 5-year unrelated death rate was 4.6% for patients before 2000 vs. 9.1% for patients after 2000 (p=0.026). Thus, the lack of a significant improvement of survival after the era of monoclonal antibodies is partly due to the doubling of WM-unrelated deaths as a result of the increasing numbers of patients of advanced age who are diagnosed and treated for WM. Additional follow up is needed for patients after 2000 in order to evaluate the WM-related risk of death at later time points (at 10 or 15 years). In conclusion, this is the first analysis in a large cohort of patients with symptomatic WM in which WM-unrelated death is treated as a competing risk. Many patients of advanced age die of causes unrelated to WM and this fact should be taken into account in the evaluation of long term outcomes and the design of clinical trials in patients with WM, especially since more patients of advanced age are diagnosed and treated for WM.

Abstract Background We describe the pattern and incidence of SMNs with 10 additional years of follow-up of an international cohort (Bhatia, N Engl J Med, 1996; Bhatia, J Clin Oncol, 2003) of children with HL diagnosed between 1955 and 1986 at age 16 y or younger. Methods Medical record review was used to identify SMNs, define vital status and describe therapeutic exposures. Pathology reports served to validate SMNs. Cumulative incidence (CI) utilized competing risk methods. Standardized incidence ratio (SIR) and absolute excess risk (AER/10,000 p-y) utilized age-, gender- and year-matched rates in the general population. Cox regression techniques (using calendar time as time scale) identified predictors of SMN risk. Results The cohort included 1023 patients diagnosed with HL at a median age of 11 y, and followed for a median of 26.8 y (IQR, 16.4-33.7). Eighty-nine percent had received radiation, either alone (22%), or in combination with chemotherapy (67%). Alkylating agent (AA) score was defined as follows: 1 AA for 6 m = AA score of 1; 2 AA for 6 m or 1 AA for 12 m = AA score of 2, etc. The AA score was 1-2 for 54% and 3+ for 16%; 30% did not receive AA. A total of 188 solid SMNs developed in 139 patients (breast [54], thyroid [24], lung [11], colorectal [11], bone [8], other malignancies [80]. Table summarizes SIR (95%CI), CI, and AER by attained age. The cohort was at an 11.1-fold increased risk of developing solid SMNs (excluding non-melanoma skin cancers) compared with the general population (95% CI, 9.4-13.0). CI of solid SMNs was 25.2% at 40 y from HL diagnosis (Fig 1). Among patients aged ≥40 y, 79% of total AER was attributable to breast, thyroid, colorectal and lung SMNs (Table). Thirty-seven patients developed >1 solid SMN; the cumulative incidence of the 2nd SMN was 19.6% at 10 years from diagnosis of the 1st SMN. Breast Cancer: Females (n=41) had a 20.9-fold increased risk, and males (n=3) a 45.8-fold increased risk c/w general population. Age at HL of 10-16 y vs. <10 y (RR=9.7, 95%CI, 2.3-40.6, p=0.002), and exposure to chest radiation (RR=5.9, 95%CI, 1.4-25.9) were associated with increased risk. Among females aged 10-16 y at chest radiation, cumulative incidence was 24.3% by age 45 y, as opposed to 2.6% for those <10 y, p=0.001 (Fig 2). Exposure to AA was associated with a lower risk (RR=0.4, p=0.002). Diagnosis of HL after 1975 was associated with decreased risk (RR=0.25, 95%CI 0.12-0.53), explained, in part by the increasing use of AA after 1975 (78%) vs. before 1975 (61%). By age 40 y, the risk of breast cancer among females exposed to chest radiation at age 10-16 y (18.2%) was comparable to the risk for BRCA1 mutation carriers (15%-20% by age 40 y; Chen, J Clin Oncol, 2007). Lung cancer: Ten of 11 lung cancer cases were diagnosed in males (males: SIR=24.7; females: SIR=3.2, p=0.05); all had received neck/chest radiation. The CI of lung cancer among males was 3.8% by age 50 y, comparable to the risk among male smokers (2% by age 50 y, Bilello, Clinics Chest Med, 2002). Colorectal cancer: There was a 11.5-fold increased risk c/w general population. The CI among those with abdominal/pelvic radiation was 4.1% by age 50 y ; this risk is higher than that observed in individuals with ≥2 first degree relatives affected with colorectal cancer (1.2% by age 50 y, Butterworth, Eur J Cancer, 2006). Thyroid cancer: Survivors had a 22.2-fold increased risk; all developed within radiation field. Females (RR=4.3, 95%CI 1.8-10.4) were at increased risk. Conclusion In this cohort of HL survivors with 20,344 p-y of follow-up, the greatest excess risk of SMNs among those > 40 y was attributable to breast, thyroid, colorectal and lung SMNs. Observed risks for the most common SMNs were comparable to or greater than known high-risk groups within the general population. Disclosures: No relevant conflicts of interest to declare.

Abstract Background VMP and Rd are two of the most efficient and widely accepted regimens in the treatment of elderly newly diagnosed MM patients. In order to further improve the outcome of elderly patients, one possibility would be to use regimens including all these drugs simultaneously, but this may result into high toxicity. Alternatively, the use of these regimens (VMP and Rd) in a sequential or alternating scheme could improve the treatment of elderly patients. We hypothesized the alternating scheme would minimize the emergence of resistant clones, and would reduce the cumulative toxicity. In order to test this hypothesis we decided to compare VMP and RD in a sequential vs an alternating scheme. Patients and methods 241 patients were randomized to receive a sequential scheme consisting on 9 cycles of VMP followed by 9 cycles of Rd or the same regimens in an alternating approach (one cycle of VMP alternating with one Rd (half of the patients started by VMP and half by Rd) up to 18 cycles). VMP included the iv administration of bortezomib 1.3 mg/m2 twice weekly for 1 six-weeks cycle, followed by once weekly for 8 four-weeks cycles in combination with oral melphalan 9 mg/m2 and prednisone 60 mg/m2 once daily on days 1–4 of each cycle. Rd treatment consisted on lenalidomide 25 mg daily on days 1-21 plus dexamethasone 40 mg weekly. Results 121 patients were allocated to receive the sequential scheme and 120 the alternating regimen. Both arms were well balanced according to the baseline characteristics. 52% patients in the sequential arm and 55% in the alternating and had high risk cytogenetic abnormalities (t(4;14), t(14;16), del17p or 1q gains). After 9 cycles of treatment, in the sequential arm, 35 out of 66 (54%) achieved at least VGPR vs 51 out of 65 patients (78%) in the alternating arm (p=0.002), including sCR/CR rate of 28% vs 38% in the sequential and alternating arms, respectively (p=NS). Seven patients in each arm achieved immunophenotypic CR. Moreover, while four patients progressed in the sequential arm under treatment with VMP, no patients in the alternating scheme developed disease progression during the first 9 cycles, After a median follow up of 12 months, there was a trend for shorter TTP in the sequential as compared with the alternating scheme (18 m-TTP of 83% vs 89% (p=NS)). In terms of OS, 83% of patients in the sequential arm were alive at 18 m versus 93% in the alternating (p=NS). Patients who achieved sCR/CR had a significantly longer 18 m-TTP as compared with patients who didn’t achieve it in both sequential (100% vs 71%; p=0.006) and alternating arms (100% vs 79%; p=0.006) and this translated into a significant benefit in OS. No differences were observed in overall response rates and CR rates in standard and high risk patients. The 18 m-TTP was similar in standard and high risk groups in both sequential (86% vs 81%) and alternating arms (84% vs 94%), noting that 94% of patients receiving the alternating scheme were progression-free at 18 months. Regarding hematologic toxicity, the frequency of G3-4 neutropenia was slightly lower in the sequential than in the alternating arm (16% and 23%) and the same trend was observed for G3-4 thrombocytopenia (16% vs 20%). Concerning non-hematologic toxicity, 5% and 4% of the patients in the sequential and alternating arms developed G3-4 infections, respectively; the rate of G3-4 skin rash was 4% in the sequential and 3% in the alternating arm; 4% of patients in the sequential arm developed G3-4 peripheral neuropathy and 3% in the sequential arm. The rate of grade 3-4 thrombotic events was 2% in both arms. Nevertheless, the detailed evaluation of the toxicity will be done at the completion of the trial when all patients will have received the same amount of drugs in either a sequential or an alternating scheme (at the present time, 42 patients in the sequential arm were not yet at risk for the development of lenalidomide-related side effects). Conclusions The administration of melphalan, bortezomib, lenalidomide and steroids in elderly MM patients in a sequential or alternating scheme is feasible. Although longer follow-up is necessary, the alternating scheme may be superior in terms of response rate and outcome, as result of the early exposure of the plasma cell to different agents. Toxicity profile is acceptable. Aparently both schemes of therapy seems to overcome the poor prognosis of high risk cytogenetic. Disclosures: Mateos: Janssen, Celgene: Honoraria.

Abstract BACKGROUND AND AIMS In patients with myelodysplastic syndromes (MDS) several validated prognostic scores, such as IPSS and R-IPSS, are available to assess the risk of AML progression and predict overall survival (OS) as well as leukemia-free survival (LFS). A number of molecular aberrations can be identified in MDS. However, differently from AML, none of the current prognostic indexes takes into account molecular profile at diagnosis. WT1 expression has often been evaluated in acute leukemias and MDS. High WT1 expression levels on bone marrow at diagnosis have been reported to identify MDS patients who are at high risk of progression to AML. BAALC (Brain And Acute Leukemia Cytoplasmic) hyper-expression has been associated with a poor prognosis in AML patients, whereas its prognostic value in MDS is not yet clearly defined. The aim of our study was to determine if combined assessment of WT1 and BAALC expression levels at diagnosis could be predictive of leukemic evolution. MATERIALS AND METHODS We selected 86 patients with available WT1 and BAALC expression levels on BM samples at diagnosis. According to IPSS score, 22 patient were considered low-risk, 27 intermediate-1 and 28 intermediate-2 or high risk. Patients underwent different treatment schedules including supportive care, erythropoietin, hypomethylating and immunomodulating agents, according to their risk group. Median follow-up was 36 months (range 4 -121 months). Leukemia-free survival (LFS) was calculated from the diagnosis until last follow-up or documented leukemic progression as defined in literature. LFS was estimated using the Kaplan–Meier method. All Real-Time PCR were performed on DNA Engine 2 (Opticon®, MJ Research®). WT1 copy number/Abl copy number 1000x104 was used as cut-off value for high WT1 expression, a level of 1000x104 BAALC copy number/Abl copy number was set as cut-off for BAALC hyper-expression. RESULTS After a median time of 32 months, 43 patients died. The main cause of death was leukemic evolution (accounting for 31/43 deaths, 72%), other causes were cardiovascular events and infections (data not shown). The risk of death by any cause was significantly affected by leukemic evolution, diagnosis according to WHO classification and molecular expression profile at diagnosis. Multivariate analysis showed that leukemic evolution was an independent predictor of death (p <0.001). Twenty-nine leukemic evolutions were observed. Median LFS was 34 months. The probability of leukemic evolution was significantly affected by karyotype, IPSS and R-IPSS scores, diagnosis according to WHO classification, and molecular profile at diagnosis. According to our data WT1 and BAALC combined expression levels further enhanced prognostic stratification. In IPSS Int-1, Int-2/high and in R-IPSS high risk groups, low levels of expression resulted in significantly lower probability of leukemic progression, whereas high levels predicted poor outcome. Furthermore, in patients assigned to IPSS unfavorable prognostic groups, low levels of WT1 and BAALC seemed to predict a significantly longer LFS. In the univariate analysis LFS duration was significantly affected by WT1 and BAALC expression levels (fig. 1), IPSS and R-IPSS scores, karyotype and WHO classification at diagnosis. A multivariate Cox Regression model showed that LFS duration was significantly influenced only by molecular profile at diagnosis and R-IPSS risk group (p <0.001 and p <0.01, respectively). Median OS was 32 months. In univariate analysis OS was significantly influenced by diagnosis according to WHO classification, karyotype, R-IPSS score, leukemic evolution and molecular profile expression at diagnosis. The multivariate model disclosed molecular expression profile, R-IPSS score and leukemic evolution as independent predictor of OS (p <0.02, <0.03 and <0.01, respectively). CONCLUSIONS In MDS patients combined WT1 and BAALC expression levels on bone marrow samples at diagnosis is a reliable predictor of risk of AML progression, LFS and OS. This can improve risk stratification especially in intermediate and high risk groups and may lead to a risk tailored therapy. Figure 1: LFS according to molecular profile Figure 1:.

Long Term Follow Up

5509 Background: ICON1 and a meta-analysis of all relevant trials demonstrated an improvement in 5 year recurrence-free and overall survival (RFS and OS) for women with early-stage epithelial ovarian cancer (ES EOC) treated with adjuvant chemotherapy compared to no adjuvant chemotherapy. We aimed to determine if this initial benefit is maintained long-term and whether benefit is different with different risk groups of patients defined by stage, grade and histology. Method: 477 women with ES EOC were recruited from centres in Italy (271 women) UK (195) Switzerland (11) between August 1991 and January 2000. 5-year results were presented at ASCO 2001. Systematic long-term follow up was planned and completed in May 2006. Results: With a median follow-up of 9.2 years, 168 women have developed recurrent disease or died and 144 women have died. The Hazard Ratio (HR) for RFS of 0.70 in favour of adjuvant chemotherapy (95% CI 0.52–0.95 p= 0.023) translated into an improvement of 10-year absolute RFS of 10% from 57 to 67%. For OS, HR was 0.74 (95% CI 0.53–1.02 p= 0.066), a corresponding improvement in 10-year absolute OS of 8% from 64% to 72%. 26% of patients died from causes other than ovarian cancer. Stage I patients were grouped as low (Ia, grade 1), medium (Ia grade 2, Ib or Ic grade 1) and high risk (Ia, grade 3, Ib or IC grade 2 or 3, any clear cell). The test of interaction between risk groups and adjuvant treatment for RFS and OS was 0.055 and 0.13, respectively. The HR, 95%CI and p value are summarised in the table . Conclusions The long-term benefit of adjuvant treatment on RFS is confirmed. There is clear evidence that adjuvant chemotherapy reduces the risk of recurrence/death or death alone in high-risk patients but not in the low-risk group. [Table: see text] [Table: see text]

333 Background: High-risk, localized prostate cancer has a poor prognosis. We hypothesized that adj docetaxel (D) and prednisone and long-term (24 mos) androgen suppression (AS) and radiation therapy (RT) would improve overall survival (OS) and tested this in NRG/RTOG 0521. Results with med follow-up of 5.7 yrs were reported (JCO 37:1159, 2019), showing a benefit of D (HR=0.69, 90% CI: 0.49-0.97, 1-sided p=0.034). Med follow-up is now 10.4 yrs and we report updated results for OS and metastasis (DM). Methods: NRG/RTOG 0521 opened 12/05 and closed 8/09 with targeted accrual of 600 and designed to detect a HR of 0.49, based on improvement in 4-yr OS from 86 to 93%. With 0.05 1-sided type I error and 90% power >78 deaths were required. Pts were stratified by predefined risk groups. Group 1: Gl 9-10, any T; Group 2: Gl 8, PSA<20, T≥T2; Group 3: Gl 8, PSA≥20, any T; Group 4: Gl 7, PSA≥20, any T. maxPSA ≤150. RT dose was 75.6 Gy. Chemo consisted of 6, 21-day cycles of D starting 28 days after RT. Results: Of 612 accrued, 563 were eligible/available for analysis. By risk group 1-4, there were 297, 116, 64, and 86 pts. Med PSA 15 ng/mL. 10-yr OS rates were 64% [95% CI: 58-70%] for AS+RT and 69% [95% CI: 63-75%] for AS+RT+CT (HR = 0.89, 90% CI: 0.70, 1.13, 1-sided p=0.22). However there was evidence of non-proportional hazards (Grambsch-Therneau test, p=0.016). Thus survival was alternatively evaluated with restricted mean survival time (RMST). The difference in RMST at 10 yrs was 0.42 yrs (90% CI: 0.07-0.77, 2-sided p=0.048). Cumulative incidence of DM at 10 yrs was 22% [95% CI: 17-27%] for AS+RT and 20% [95% CI: 15-25%] for AS+RT+CT (2-sided log-rank p=0.29). At 10 years most deaths occurred in risk group 1: 62 in AS+RT and 50 in AS+RT+CT (HR= 0.93, 95% CI: 0.66-1.32, 2-sided log-rank p=0.16). There was no new related Grade 5 toxicity. Conclusions: OS findings, reported after follow-up of 5.7 yrs, demonstrated a small beneficial effect of adding D to AS and RT. With longer follow-up the benefit of D remains, but the HR varies over time and the OS curves have converged.

AbstractIn July 1982, five Hartford hospitals embarked on a joint hospital-sponsored program to immunize high-risk employees against hepatitis B virus (HBV). The program included a questionnaire to characterize relative risk, serology for anti-HBs, vaccination and a follow-up survey of vaccine non-recipients.Of 2,065 employees who were considered to be at high-risk for infection with HBV, 1,894 (91.7%) responded to the screening questionnaire and 1,279 (67.5%) were tested for anti-HBs serology. The prevalence of antibody varied from hospital to hospital; the highest prevalence (10.9%) was observed at one of the urban university-affiliated community hospitals and the lowest prevalence (4.1%) was reported from the smaller, rural hospital. The prevalence of antibody also varied greatly within the high-risk groups; the highest prevalence of antibody was seen among surgical house officers (15%). The rate of acceptance of vaccine among hospitals ranged from 57.5% to 23.7%. Reasons for vaccine non-acceptance included fear of as yet unknown side effects, perceived low risk of hepatitis acquisition and possible effects on present or future pregnancies.Our experience illustrates some of the epidemiologic and practical aspects that must be addressed in administering a hospital-based HBV vaccine program. Among the five hospitals, we saw marked inter- and intra-hospital variations in the prevalence of anti-HBs among high-risk employees. More significantly, we observed unexpectedly low rates of vaccine acceptance among high-risk personnel.

Abstract Introduction: We previously reported a prognostic scoring system in CLL using pre-treatment factors in patients treated with ibrutinib [Ahn et al, 2016 ASH Annual Meeting]. Here we present long-term follow-up results and validation of the prognostic models in a large independent cohort of patients. We also determine the incidence of resistance-conferring mutations in BTK and PLCG2 genes in different clinical risk groups. Methods and Patients: The discovery cohort comprised 84 CLL patients on a phase II study with either TP53 aberration (deletion 17p or TP53 mutation) or age ≥65 years (NCT01500733). The validation cohort comprised 607 patients pooled from four phase II and III studies for ibrutinib in treatment-naïve or relapsed/refractory CLL (NCT01105247; NCT01578707; NCT01722487; NCT01744691). All patients received single-agent ibrutinib 420mg once daily. We used Cox regression models to identify independent predictors of PFS, Kaplan-Meier method to estimate probabilities of PFS, log-rank test to compare PFS, and Cochran-Armitage trend test to compare the incidence of mutation among subgroups. We used R version 3.5.0 or SAS® version 9.3 for statistical analyses. For biomarker correlation, we tested cellular DNA or cell-free DNA collected from patients in the discovery cohort with the targeted sequencing of BTK and PLCG2 genes. Result: At a median follow-up of 5.2 years, 28 (33.3%) of 84 patients in the discovery cohort progressed or died. 52 (61.9%) patients had treatment-naïve CLL. Independent factors of PFS on univariate analysis were; TP53 aberration, prior treatment, and β-2 microglobulin (B2M) >4mg/L (P<0.05 for all tests). Unmutated IGHV and advanced Rai stage (III/IV) showed a trend toward inferior outcome without reaching statistical significance. Because higher levels of B2M were associated with relapsed/refractory CLL, we performed two multivariate Cox regression models to assess B2M and prior treatment status separately. Risk groups were determined by the presence of TP53 aberration, advanced Rai stage, and B2M >4mg/L for Model 1, and TP53 aberration, advanced Rai stage, and relapsed/refractory CLL for Model 2 (Table 1). The high-risk group had all three adverse risk factors; the intermediate-risk group had two risk factors; and the low-risk group, none or one. The median PFS of the high-risk group was 38.9 months for Model 1 and 38.4 months for Model 2, and was significantly shorter than those of intermediate and low-risk groups. In the validation cohort, 254 (41.8%) of 607 patients progressed or died at a median follow-up of 4.2 years. 167 (27.5%) patients had treatment-naïve CLL. Both models showed statistically significant differences in PFS by risk groups (Table 1). For the high-risk group, 4-year PFS was 30.2% in Model 1 and 30.5% in Model 2, which were inferior to those of intermediate (53.4 and 52.4%) and low-risk groups (68.7 and 73.7%). Model 1 classified 20% of patients and Model 2 classified 28% of patients to the high-risk group. BTK and PLCG2 mutations are common genetic drivers of ibrutinib resistance in CLL. To determine whether the incidence of these mutations correlates with prognostic risk groups, we performed targeted sequencing of BTK and PLCG2 of samples collected from patients in the discovery cohort. We used cell-free DNA for patients who received long-term ibrutinib (≥3 years) and had low circulating tumor burden, and cellular DNA, for samples collected within 3 years on ibrutinib or at progression. Of 84 patients, 69 (82.1%) were tested at least once, and 37 (44.0%) were tested at least twice. The frequency of testing was similar across the risk groups by two models (P>0.05). The cumulative incidences of mutations at 5 years in the low-, intermediate-, and high-risk groups were: 21.4%, 44.8% and 50%, respectively, by Model 1 (P=0.02); and 22.6%, 41.4% and 66.7%, respectively, by Model 2 (P=0.01). Conclusion: We developed and validated prognostic models to predict the risk of disease progression or death in CLL patients treated with ibrutinib. Risk groups classified by three commonly available pre-treatment factors showed statistically significant differences in PFS. The clinically-defined high-risk disease was linked to higher propensity to develop clonal evolution with BTK and/or PLCG2 mutations, which heralded ibrutinib resistance.

The Difference

Objective. To investigate the value of the PTX-3 test in evaluating the prognosis of acute pulmonary embolism (APE). Method. 117 APE patients were selected and divided into two groups according to plasma PTX-3 levels, including the group in which PTX−3≥3.0 ng/mL (n=42) and the group in which PTX−3<3.0 ng/mL (n=75). Patients were stratified into high-risk, medium-risk, and low-risk groups according to the Wells scores, and the PTX-3 levels were compared among the groups. Patients had been followed-up as well. Results. According to the Wells scores, 11 patients were classified as high-risk (9.4%) and 68 were medium-risk (58.1%), while 38 were low-risk (32.5%). The PTX-3 levels in different risk groups were statistically different (all P<0.05). During the follow-up period, 6 deaths occurred in the group with elevated PTX-3 (≥3.0 ng/mL), while 2 deaths occurred in the group with nonelevated PTX-3 (<3.0 ng/mL). The difference between the two groups was statistically significant (P<0.01). 13 patients were hospitalized due to recurrent pulmonary embolism, of which 12 were in the group with elevated PTX-3 (≥3.0 ng/mL), while 1 patient was in the group with nonelevated PTX-3 (<3.0 ng/mL). The difference was statistically significant (P<0.01). Conclusion. The plasma PTX-3 level in APE patients is correlated with PE risk stratification. There is a significant correlation between PTX-3 levels and PE-related cardiac deaths, as well as the prognosis of recurrent PE. PTX-3 can be used as a clinical indicator of PE prognosis.
