Early Intensive Therapy in Multiple Myeloma Using Tandem Transplantation with Novel Conditioning and Two Years Maintenance: A Single Institution Experience

Abstract Introduction The role of early intensive treatment of multiple myeloma, including tandem autologous stem cell transplantation( ASCT) with bortezomib, thalidomide, dexamethasone( VDT) and melphalan 200mg/m2 as a preparative regimen, followed by 2 years of combination agent maintenance therapy, is being studied. We sought to analyze a cohort of patients who received early intensive treatment at the University of Iowa between 2012 and 2016. Patients and Methods All consecutive patients who received early( < 12 months since diagnosis) tandem ASCT and have completed at least 2 years of maintenance therapy between 2012 and 2016 were included for analysis. Planned maintenance therapy consisted of a combination of VDT in 28 day cycles for year 1 and bortezomib, cyclophosphamide and dexamethasone(VCD) in 28 day cycles for year 2. Alternate regimen were used in case of toxicities. The patients were considered to have high risk cytogenetics if they had 17p deletion, t(14;16), amp 1q, or t(4;14) by FISH. Event-free (EFS) and overall survival (OS) probabilities were estimated and plotted using the Kaplan-Meier method. For EFS, time was calculated from date of first transplant to relapse or death due to any cause. Treatment-related mortality was defined as death during transplant phase or maintenance phase due to causes other than disease relapse.The effect of clinical characteristics on outcomes was evaluated using Cox regression models. Estimated effects of predictors are reported as hazard ratios (HR) along with 95% confidence intervals. All statistical testing was two-sided and assessed for significance at the 5% level using SAS v9.4 (SAS Institute, Cary, NC). Responses were measured using IMWG consensus criteria. Results A total of 135 patients met the criteria for inclusion. Key patient characteristics are shown in table 1. The median age at first transplant was 58 years. HCT-CI was high in 68% of patients. 36% of the patients were ISS stage III, and high risk cytogenetics were present in 56%. Preparative regimen was VTD-Mel 200 in 88.9% of patients. Following the first transplant, 59% of patients had achieved CR, and following the second transplant 94.4% of patients achieved CR. At the time of median follow up, 27.4% of patients had died. The cause of death was infection (25%), organ failure (11%), relapsing myeloma (28%) or other (36%). Univariable analysis identified a statistically significant association only for age with risk of progression or death. Kaplan-Meier curves for progression free survival and overall survival in patients with high risk or low risk cytogenetics are shown in Figures 1 and 2 respectively. The hazard ratio for progression free survival and overall survival in patients with high risk vs low risk cytogenetics was 0.86 (95% confidence interval 0.45 - 1.64, p=0.65), and 0.88 (95% confidence interval 0.45 - 1.73, p=0.71), respectively. The 3 year EFS and OS of patients who received early tandem ASCT followed by 2 years of maintenance were 73% and 72%, respectively. Following the 2nd autologous transplant, 128 of 135( 94%) patients were started on maintenance therapy. VTD ( 74%) and VRD (6%) were the most common regimens used. Fifty six patients completed maintenance therapy for 1 year without regimen change, and 60 required regimen change due to toxicities. VRD (20), VPomD (9) and VRMp (8) were the most commonly used alternative regimens in the case of toxicities. Following year 1 of maintenance, 96 patients (75%) started a second year of maintenance. VCD (30%) or RD (23%) were the most common regimens. 63(43%) patients completed 2 years of combination maintenance therapy. Grade III-V non-hematologic toxicities during the combined maintenance phase were infection (56%) and peripheral neuropathy (23%) and hematologic toxicities were thrombocytopenia (13%), neutropenia (12%) and anemia (8%). Conclusion According to our results, patients with high risk cytogenetics did not have an inferior PFS and OS. These results suggest that in newly diagnosed MM patients, upfront treatment using novel conditioning regimen and tandem ASCT followed by intensive maintenance therapy can result in a very high CR rates, particularly in patients with high risk cytogenetics. Infections and peripheral neuropathies were the most common non-hematologic toxicities during maintenance. Longer follow up will determine further impact of maintenance therapy.

Abstract Abstract 4156 Background: Chromosomal abnormalities detected either by conventional cytogenetics (CC) or interphase fluorescence in situ hybridization (FISH) have emerged as important prognostic markers in patients with multiple myeloma (MM) and are used to stratify patients into standard-risk (SR) or high-risk (HR) disease. HR myeloma is associated with shorter remission and survival even with novel agents and autologous hematopoietic stem cell transplantation (auto-HCT). In this report, we describe the outcome of patients with myeloma who received auto-HCT at our institution between January 2008 and December 2009, and had CC and FISH analyses available before auto-HCT to identify HR or SR disease. Methods: Primary objective was to compare the response rate, transplant-related mortality (TRM), time to progression (TTP), progression-free survival (PFS) and overall survival (OS) between HR and SR myeloma. HR myeloma was defined as having deletion of chromosomal 13 or 13q, t(4;14), and del17p by CC; or detection of t(4;14), t(14;16), or del17p by FISH in the bone marrow plasma cells (Munshi, N et al. Blood 2011 117: 4696–4700). Normal or any other CC or FISH abnormalities were considered SR. Response was assessed according to international uniform response criteria for myeloma (BGM Durie et al. Leukemia 2006 20(10):1–7). Kaplan & Meier curves were generated to calculate progression free survival (PFS) and overall survival (OS). Results: Between Jan 2008- Dec 2009, we identified 205 patients, who received auto-HCT at our institution and had pre-transplant CC and FISH analyses available. Twenty-eight patients (14%) had HR while 177 (86%) had SR myeloma. Table 1 summarizes patient characteristics and outcomes for HR and SR patients. Nine HR (30%) and 29 (16%) SR patients had international staging system (ISS) stage III at diagnosis (p=0.04). Twenty-one HR patients (70%) and 91 SR patients (51%) received induction therapy with a bortezomib-based regimen (p=0.01). Thirteen (46%) HR patients and 62 (35%) SR patients received post auto-HCT maintenance therapy (p=0.24). Nineteen HR patients (69%) and 165 SR patients (92%) achieved a CR, VGPR or PR after auto-HCT (p=0.00001). The median follow up in HR and SR patients was 14.5 months (2–30) and 12 months (1–35), respectively. Twenty-two (79%) HR and 46 (25%) SR patients had progressed at last follow up (p=0.00001). Similarly, 12 (43%) HR and 12 (7%) SR patients had died at last follow up (p<0.0001). Median PFS was 9.1 months in HR while it was 30.8 months in SR patients (p=0.000001). Median OS in HR was 19 months while median OS has not yet been reached in SR patients (p=0.000001). In HR patients only the use of maintenance therapy post auto-HCT significantly improved PFS and OS (p=0.001 and p=0.0007, respectively). Conclusion: Patients with HR myeloma had significantly worse outcome than patients with SR disease, even with novel agents and auto-HCT. In HR patients, maintenance therapy was associated with longer PFS and OS. Disclosures: No relevant conflicts of interest to declare.

The Impact

Abstract Introduction : To date, the ELN recommendation and NCCN guidelines are the principle mile stones to follow up the treatment response and to make the decision of TKIs switching. However, in real life practice, many factors influence changing the real switching date from the date had an indication. This study aims to analyze the impact of early switching to second line TKI, nilotinib, in real life practice, for the CML patients who failed, had sub-optimal response or were intolerant to imatinib. Methods : This prospective study was conducted through 7 medical centers in Thailand between 1st of September 2009 and 31st of August 2011. Adult CML patients of age ≥ 18 years old, in chronic and accelerated phase, who had failure, suboptimal response or intolerance to imatinib, based on ELN 2009 guideline, were included and were eligible with nilotinib 400 mg twice daily. Prospective data collection for 24 months of each patient was performed. The main objective was to identify the impact of early switching to nilotinib on major molecular response (MMR). The other objectives were to observe the efficacy of nilotinib including overall survival, progression free survival and the safety. The survival results were presented as Kaplan-Meier survival curves. For the comparison of the treatment groups, the Kaplan-Meier estimator with the corresponding log-rank test for equality of survivor functions across treatment group was applied. Results : The final 108 cases were analysed. The median age was 47 (17-79) years with the proportion of male to female of 1.4:1 respectively. The median duration of the prior imatinib treatment was 18 months (2-142 months). The median duration between the date of indication and the date of real switching was 3.1 months (0-62.8 months) with 50% changing less than 3 months, 26.9% between 3 months and 12 months, and 23.1% changing longer than 12 months. The indication of switching included 63.6% failure to imatinib, 29% intolerance to imatinib and 7.4% suboptimal to imatinib. On the nilotinib switching, 70.4% completed 24 months follow-up, and 29.6% discontinued treatment mostly because of unsatisfactory results or adverse events. Evaluation was made every 3 months based on 2009 ELN recommendation. At 3 months, 57%, 20%, and 8% of the patients achieved CHR, CCyR and MMR, respectively. Those who did not achieve CHR at 3 months never achieved MMR, while 86 % of those who achieved CCyR at 3 months achieved MMR. All CML achieving MMR at 3 months had sustained MMR throughout the study period (24 months). Imatinib suboptimal response had better outcome than imatinib failure and imatinib intolerance groups. A preliminary analysis of BCR-ABL mutation was performed on 90 cases, and mutations were found on 21 cases. Two of them were T315I which were excluded from the study. The cases with mutation had poorer response to treatment than those without mutation. There was one case with initial G250E mutation developing T315I mutation after treatment with nilotinib. At 24 months, one case progressed to accelerated phase and 3 cases progressed to blastic transformation. The 2-year overall survival and 2-year progression-free survival and were 98.9% and 96.9% (figure 1 and 2), respectively. The interquatile analysis was done to identify the groups of cumulative MMR according to the duration between the date of indication and the date of real switching to nilotinib. The patients who switched to nilotinib within 12 months after date of indication could have a greater chance to achieved MMR than those who switched treatment later than 12 months (p(log-rank) = 0.002) (figure 3). Skin rash, musculoskeletal pain, and infection were the three most common non-hematologic adverse events, However, most of them were grade 1-2, except for 4 cases with grade 3-4 infections. Grade 3-4 hematologic adverse events included thrombocytopenia (12%), neutropenia (11%), anemia (5%) and leucopenia (4%), and most of them were manageable. Although biochemical abnormalities were commonly found, most of them were mild. Conclusions : Nilotinib, as a second line treatment showed excellent efficacy and tolerability. Indication for nilotinib treatment, initial mutation status and depth of response at 3 months after treatment can predict outcomes of the patients. However, the patients will have a greater chance to achieve MMR if they switched to nilotinib within 12 months after the date of indication for changing.

Abstract Introduction: Combination therapy for longer periods but at low dose, also called metronomic scheduling, might be an effective manner to treat patients with relapsing myeloma. In particular if the used agents attack the malignant clone in an alternative manner. Therefore we used the combination of bortezomib, dexametasone and daily low dose of oral cyclophosphamide as an induction regimen followed by one year of maintenance therapy consisting of bortezomib and cyclophosphamide. Methods: Relapsing myeloma patients, bortezomib naïve, were treated with three cycles of 1.3 mg/m2 bortezomib at day 1, 4, 8 and 11, cyclophosphamide 50 mg daily, and 20 mg dexamethasone at day 1, 2, 4, 5, 8, 9, 11 and 12 followed by three cycles of bortezomib 1.6 mg/m2 (day 1, 8, 15 and 2), cyclophosphamide (50 mg) daily and dexamethasone (20 mg) at day 1, 2, 8, 9, 15, 16, 22 and 23. Maintenance therapy consisting of bortezomib 1.3 mg/m2 every two weeks and daily dose of 50 mg cyclophosphamide for one year was applied to patients in partial or complete remission. Primary endpoints were toxicity during re-induction and maintenance therapy. Secondary endpoints were response to treatment and progression free and overall survival. Results: 59 patients with relapsing multiple myeloma were included of whom 69% were in first relapse (Table 1). The upfront treatment consisted mainly of thalidomide-based and vincristine-based chemotherapy and 40% of the patients have been treated with an autologous stem cell transplantation. All 6 cycles of induction chemotherapy could be given in 49% of the patients. Premature discontinuation before starting maintenance therapy was due to toxicity (31%), progressive disease (7%), death (7%) or other reasons (6%). Myelosuppression was the most common side effect with WHO grade 3-4 in 31% of the patients. Neuropathy grade 3-4 was observed in 16% of patients, partially due to the fact that bortezomib was given intravenously during the first 2 yrs of the protocol which included 76% of the patients. Maintenance therapy was started in 47% of the patients with a median duration of 7.3 months (range 0.36.-13.4). Grade 3-4 toxicity was observed in 25% of the patients including infections (n=3) and myelosuppression (n=3) which did not resulted in discontinuation of therapy. Median follow up time was 29 months with an overall response of 62%, and a very good partial response (VGPR), complete remission (CR) in 21% and 7% of the patients respectively. During the maintenance phase an improvement in responsiveness was observed in 25% of the patients. The CR rate increased with 9% to a total of 16%. VGPR rate was 20% and 16% of the patient had a PR. At end of the maintenance therapy 50% of patients started with maintenance had stable disease. The median progression free survival (PFS) was 17.2 months (range 0.13 – 43.5) as depicted in figure 1. and the median overall survival was 21.6 months (range 0.46-54.4, figure 2). During follow up 33 % of the patients died due to progression of MM. Conclusion: The present study demonstrates that combination therapy with bortezomib, continuous low dose cyclophosphamide and dexamethasone is an effective and manageable regimen. Adding a year of maintenance was feasible with limited side effects and an increase in CR rate.

Abstract Background: Despite an abundance of effective therapeutic options, advanced stage follicular lymphoma (FL) remains incurable. Further, prospective trials consistently demonstrate that 20% of patients relapse within 2 years and ultimately have an inferior survival (Casulo 2015). Maintenace rituximab following chemoimmunotherapy induction is able to delay disease progression but has not demonstrated a benefit in overall survival (Salles 2011). Additionally, radioimmunotherapy (RIT) is one of the most effective single agent options in FL but is not commonly utilized as part of upfront treatment. As such, the role of both remains unclear. Based on results demonstrated with RIT consolidation in SWOG 0016 and the efficacy of rituximab maintenance, SWOG 0801 was designed as a phase 2 single arm trial, conducted to evaluate the utility of consolidative RIT and sequential maintenance rituximab following chemoimmunotherapy induction. Methods: Eligible patients (pts) with treatment naïve stage III/IV or bulky stage II FL received RCHOP for 6 cycles (without rituximab for the last 2 cycles) followed by iodine-131 tositumomab and subsequent rituximab administered every 3 months for up to 4 years. The primary endpoint was progression-free survival (PFS) at 3 years. Secondary endpoints included 5-year overall survival (OS), overall response rate (ORR), and safety. Results: Of 87 pts registered to this study, 85 were deemed eligible following central pathologic review. One additional patient withdrew consent and received no treatment on protocol. Of the 84 evaluable patients, the median age was 52 years (range 29 - 80) ) and 18%, 40%, and 42%had low, intermediate and high risk FLIPI scores, respectively. Seventy-three pts completed RCHOP and I-131 tositumomab. Grade ≥3 AEs occurring ≥5% of pts included neutropenia (57%), leukopenia (40%), thrombocytopenia (20%), febrile neutropenia (17%), fatigue (10%), neuropathy (8%), anemia (7%) and hyperglycemia (5%). Reasons for discontinuation included refusal of tositumumab (6 pts), prolonged myelosuppression (2 pts), ascites (1pt), inability to provide tositumumab (1 pt), and an unrelated lower extremity wound (1 pt). Following induction and RIT, 59 complete responses and 23 partial responses were observed, for a ORR of 99% (95% CI: 93.5%, 99.9%) Sixty nine eligible patients registered to maintenance therapy with 42 completing the 4 year treatment plan. The only grade ≥3 AE that occurred in ≥5% of pts was leukopenia (5%). Twenty-seven pts discontinued maintenance therapy, including 11 in the first 2 years and 16 in the last 2 years, due to the following reasons: infection (8 pts), patient preference (8 pts), deaths (2 pts), treatment delay (2 pts), secondary solid tumors (2 pts), bowel perforation (1 pt), joint pain (1 pt), hepatic transaminase elevation (1 pt), insurance refusal (1 pt), and dose error (1 pt). Four additional secondary malignancies were reported following completion of therapy including solid tumors (3 pts) and AML (1 pt). To date, 9 deaths have occurred due to secondary malignancies (3 pts), unknown etiology (3 pts), cardiac arrest (2 pts) and non-alcoholic cirrhosis (1 pt). After median follow-up of 5.6 years (range 3-7 years), 17 events have occurred including 9 pts experiencing progressive FL resulting in a progression free survival of 90% (95% CI: 81.9%, 95.1%) at 3 years and 84%(95% CI: 74.5%, 90.6%) at 5 years (Figure). Three-year overall survival is 96% (95% CI: 89.3%, 98.8%) and 5-year overall survival is 94% (95% CI: 86.2%, 97.5%). Conclusions: SWOG 0801 demonstrates near universal responses following chemoimmunotherapy and RIT. This sequential therapeutic strategy appears to improve early outcomes as 94% of pts are without disease progression at 2 years, consistent with the best results ever demonstrated for FL in the National Clinical Trials Network. However, the majority of discontinuations occurred during maintenance suggesting that rituximab over a 4-year span is not feasible for many patients due to cumulative toxicity. Future studies investigating precision strategies in high-risk FL may consider an aggressive chemoimmunotherapy induction and RIT consolidation platform to overcome early FL progression given these promising outcomes.

Abstract Abstract 1343 Background: Multiple myeloma (MM) is the second most common hematological malignancy in the United States with an estimated 20,580 new cases in 2009. Over the past decade, the introduction of novel agents (thalidomide, lenalidomide and bortezomib) have played a pivotal role in improving response rates, duration of response, overall survival (OS) and quality of life. In this study we describe a single center experience with novel agents used for induction followed by high dose chemotherapy (HDT) and first autologous stem cell transplant (ASCT) in patients with MM. Method: A retrospective review of the medical records of 179 newly diagnosed patients with MM seen between October 2006 and December 2009 at The Ohio State University was performed. All patients received novel therapy containing thalidomide, bortezomib or lenalidomide as part of an induction regimen followed by ASCT. All patients received melphalan 140mg/m2 or 200mg/m2 as preparative regimen. Kaplan-Meier estimates were used to plot progression free survival and overall survival. Results: Of the 181 patients seen, 2 were excluded because they did not receive a novel agent as part of induction treatment. Of the 179 patients analyzed, median age was 56.8 years (29-80) with 30% of patients older than 60 years. African American represented 19%. Fifty-nine percent were male, 80% had Durie-Salmon (DS) stage III while 25%, 28%, 18% represented International prognostic score (IPS) stage I, II, and III respectively with 27% unknown. Median comorbidity index score was 2 (2-7) and median Karnofsky performance score (KPS) was 90% (70-100). Thirty percent had high risk genetic profile, and 73% received one line of treatment before ASCT. The median time from diagnosis to ASCT was 8.33 months (4-58). The overall response rate (ORR) prior to transplant was 84% (9% complete (CR), 29% very good partial (VGPR), and 46% partial (PR)). The ORR post ASCT was 89% (CR 45%, VGPR 22%, PR 21%). Non relapse mortality was 1% and 3% at 100 days and 1 year respectively. At a median follow up of 31 months (7-90), 69 patients (38%) had relapsed. Median progression free survival (PFS) was 29 months with 1 and 3 years PFS of 79.3% and 61.5% respectively (Fig. 1). The OS was not reached. One and 3 years OS were 93% and 88% respectively (Fig. 1). Univariate analysis showed that time to transplant > 12 months was associated with poor outcome and decreased overall survival (HR 3.30, p = 0.008). High risk genetic profile was also found to be associated with decreased overall survival although this was not statistically significant (HR 2.31, p = 0.070). Multivariate analysis found that only time to transplant > 12 months was an independent predictor of decreased OS. Significant predictors for disease progression were high risk genetic profile and time to transplant > 12 months in patients receiving 2 or more treatments before ASCT. Conclusion: Induction with novel agents followed by HDT and ASCT improves CR rate, in our case from 9% to 45%. Median PFS (29 months) was comparable to other published data. OS was not been reached after a median follow up of 31 months. Predictors of progression include high risk genetic profile and time to transplant > 12 months. The only significant predictor for survival was time to transplant. Our study suggests that an early transplant may improve OS and PFS. An extended analysis will be presented at the meeting.

153 Background: Biochemical recurrence (BCR) after radical prostatectomy (RP) is usually defined at a PSA >0.2 ng/ml. BCR may precede clinical progression by years. Though salvage radiotherapy (SRT) is recommend to be initiated at PSA <0.5 ng/ml, its efficiency at PSA <0.2 ng/ml is not well documented. Methods: We relied on two independent post-RP cohorts. Cohort 1 (n=311, Hamburg) comprised men whose post-RP PSA levels had risen to 0.1-0.2 ng/ml. Further biochemical and clinical progression were recorded during follow-up. Cohort 2 (n=198, Berlin) were patients with BCR who received SRT (66/72 Gy) at a PSA <0.5 ng/ml. The median follow-up was 6.9 years. Post-SRT progression and overall survival were addressed by Kaplan-Meier analysis and Cox regression modelling. Results: In cohort 1, 299 (96%) men experienced further PSA progression (>0.2 ng/ml) within a median time of 7 months. Subsequent PSA rise to >0.3, >0.4, and >0.6 ng/ml was recorded in 174 (58%), 123 (41%), and 24 (8%) men, respectively. Twenty-four (8%) men developed metastases. In cohort 2, 112 men received SRT at PSA between 0.03 and 0.2 ng/ml, and 86 at 0.2-0.499 ng/ml. The latter group, had a poorer 10-years BCR-free Kaplan-Meier rate, 43% vs. 66% (p=0.051). Together with pT<3, Gleason Score <7, and post-RP PSA <0.03 ng/ml, SRT at PSA <0.2 ng/ml was an independent favorable predictor of freedom from BCR (OR=0.60, p<0.05). Ultimately, 14 patients died. However, overall survival did not significantly correlate with the pre-SRT PSA. Conclusions: The vast majority of patients with a PSA >0.1 ng/ml after RP will subsequently progress to PSA >0.2 ng/ml. Improved progression free survival can be achieved, if SRT is administered at a PSA <0.2 ng/ml. Therefore the contemporary PSA threshold for defining BCR after RP needs to be reconsidered and early sRT should be contemplated on a individual basis for optimizing oncological outcomes.

Introduction The best conditioning regimen in allogeneic stem cell transplantation (SCT) for myeloid malignancies is unknown. In the last decade, conditioning regimens based on busulfan (BU) and fludarabine (FLU) have shown a good security profile with low early toxicity and mortality but long term follow up is needed to confirm the efficacy in the disease control. Objective To analyze retrospectively the efficacy (overall survival OS, progression free survival PFS) of the conditioning regimen with FLU (40mgr/m2/4 days) and BU (3,2 mgr/kg once daily/4 days) in adult patients with myeloid neoplasms after SCT. Outcome was assessed considering age, comorbidity, disease, and donor. Patients and transplant characteristics Between 2006 and 2012, 90 patients (40 males, 50 females) underwent SCT conditioned with FB4 in our center. The median age of patients was 50 (24-74) years and 34 patients (37%) were older than 55 years. The diagnoses were 65 AML (11 secondary AML and 19 with adverse cytogenetic), 19 MDS (11 with IPSS high/intermediate 2) and 6 MPD (3 CML, 3 myelofibrosis). At time of SCT, 52 patients (80%) with AML were in first CR. High risk disease (secondary AML or with adverse cytogenetic and MDS with high/intermediate IPSS) were considered in 41 patients (45%). The HCT comorbidity index (Sorror) was low, intermediate or high in 20 (22%), 31 (34%) and 39 (43%) patients, respectively. Donor type was matched related in 42 patients (47%), matched unrelated in 30 patients (33%) and mismatched unrelated in 18 patients (20%). Stem cell source were bone marrow in 81 cases (90%). GvHD prophylaxis was done with calcineurin inhibitor associated with short course of methotrexatre or mycophenolate in all patients and Thymoglobulin was administered in 8 patients (9%). Results All patients but one engrafted. The median time to recovery >500 ANC/uL and >50000 platelets/uL was 16 days (range, 9-28) and 16 days (range, 11-455) respectively. Donor complete chimerism was achieved during first or second month in 90% cases. The incidence of acute GVHD grade II-IV and III-IV was 45% and 12% respectively. Chronic GvHD was diagnosed in 60 patients (68%) (26 mild, 18 moderate and 16 severe) and 22 patients (36%) had pulmonary affectation. Transplant related mortality at 100 days and 1 year was 5.5% and 15%. With a median follow up of 26 months (IQL 12-45), the estimated overall survival (OS) was 64% and progression free survival (PFS) was 61%. To be more than 55 years at time of SCT had a negative impact on survival (estimated OS at 40 months: 42% vs 75%, p=0.005). Neither HCT comorbidity index nor disease type had a significant influence on estimated OS at 40 months (70%, 62% and 58% in low, intermediate and high risk) and (64% in AML and 51% in MDS) respectively. However considering the group of high risk disease had worse OS (53% vs 78%, p=0.07). Although there was no significant difference, the OS in mismatched unrelated SCT was worse than matched unrelated and related SCT (40%, 63 % and 71%). Conclusion Conditioning regimen with fludarabine and busulfan (FB4) offers a good effectiveness in patients with myeloid neoplasms and allow the use of myeloablative regimen in patients with high risk disease and significant comorbidities. Only the age at time of SCT had a statically significant impact on overall survival. Disclosures: No relevant conflicts of interest to declare.

ObjectiveThe aim of the study was to report on the oncologic outcome of the disease spread to celiac lymph nodes (CLNs) in advanced-stage ovarian cancer patients.MethodsAll patients who had CLN resection as part of their cytoreductive surgery for epithelial ovarian, fallopian, or primary peritoneal cancer were identified. Patient demographic data with particular emphasis on operative records to detail the extent and distribution of the disease spread, lymphadenectomy procedures, pathologic data, and follow-up data were included.ResultsThe median follow-up was 26.3 months. The median overall survival values in the group with positive CLNs and in the group with negative CLNs were 26.9 months and 40.04 months, respectively. The median progression-free survival values in the group with metastatic CLNs and in the group with negative CLNs were 8.8 months and 20.24 months, respectively (P = 0.053). Positive CLNs were associated with progression during or within 6 months after the completion of chemotherapy (P = 0.0044). Tumor burden and extensive disease distribution were significantly associated with poor progression-free survival, short-term progression, and overall survival. In multivariate analysis, only the CLN status was independently associated with short-term progression.ConclusionsDisease in the CLN is a marker of disease severity, which is associated to a high-risk group of patients with presumed adverse tumor biology, increased risk of lymph node progression, and worst oncologic outcome.

BackgroundImmune checkpoint inhibitors (ICI) have become an increasingly utilized treatment in metastatic renal cell carcinoma (mRCC). Although they have a favorable toxicity profile, immune-related adverse events (irAEs) can have a significant impact on patients‘ quality of life. It is not well understood whether irAEs are associated with improved clinical outcomes. We investigated the relationship between irAEs and clinical outcomes in mRCC patients treated with ICI.MethodsWe performed a retrospective study of 200 patients with mRCC who received ICI at Winship Cancer Institute of Emory University from 2015–2020. Clinical outcomes were measured by overall survival (OS), progression-free survival (PFS), and clinical benefit (CB). OS and PFS were calculated from ICI-initiation to date of death and radiographic or clinical progression, respectively. CB was defined as a best radiographic response of complete response (CR), partial response (PR), or stable disease (SD) for >6 months per response evaluation criteria in solid tumors (RECIST) version 1.1. Toxicity data was collected from clinic notes and laboratory values. The association with OS and PFS was modeled by Cox proportional hazards model. Kaplan-Meier curves were created for survival estimates.ResultsMost patients were males (71%), and 78% had clear-cell RCC (ccRCC). Most patients (58%) received anti-PD-1 monotherapy. The majority were international mRCC database consortium (IMDC) intermediate (57%) or poor-risk (26%). Anti-PD-1 monotherapy was the most common (58%) treatment regimen and most patients received ICI as first (38%) or second-line (42%) treatment. One-third of patients (33%) experienced an irAE, with the most common being endocrine (13%), gastrointestinal (11%), and dermatologic (10%). Patients who experienced irAEs had significantly longer OS (HR: 0.52, 95% CI: 0.32–0.87, p=0.013), higher chance of CB (OR: 2.10, 95% CI: 1.11–4.00, p=0.023) and showed a trend towards longer PFS (HR: 0.71, 95% CI: 0.49–1.02, p=0.065) in MVA (table 1). Patients who had thyroid irAEs had significantly longer OS, PFS, and higher chance of CB in MVA (table 1). The objective response rate was higher for patients who experienced irAEs (34% vs. 18%). Patients who experienced irAEs had significantly longer median OS (44.5 vs. 18.2 months, p=0.005) and PFS (7.5 vs 3.6 months, p=0.0028) compared to patients who did not (figure 1).Abstract 637 Table 1MVA* of association between irAEs and clinical outcomesAbstract 637 Figure 1Kaplan-Meier curves of association between immune-related adverse events (irAEs) and overall survival (OS, top panel) and progression-free survival (PFS, bottom panel)ConclusionsWe showed that mRCC patients who experienced irAEs, particularly thyroid irAEs, had improved clinical outcomes. This suggests that irAEs may be prognostic of favorable outcomes in mRCC patients treated with ICI. Larger, prospective studies are needed to validate these findings.AcknowledgementsResearch reported in this publication was supported in part by the Breen Foundation and the Biostatistics Shared Resource of Winship Cancer Institute of Emory University and NIH/NCI under award number P30CA138292.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC).　Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.
