Abstract Background: Most patients (pts) with CLL present at early stages of their disease. This group is not homogenous with regard to its prognosis, and some pts show progression within 12 months after diagnosis. So far it is not clear if these pts benefit from early risk-adapted therapy. The CLL1 protocol, a randomized phase III trial of the GCLLSG, was conducted to assess if the early use of fludarabine prolongs progression free survival (PFS) in high risk (HR) CLL pts. High risk was defined by an elevated thymidine kinase (>7 U/L) or beta-2-microglobulin (>3,5 mg/L) and short lymphocyte doubling time (<12 months) or diffuse bone marrow infiltration. Combining the biological and clinical factors, at least one parameter of each group needed to be positive to qualify for the high risk cohort. Patients: From 09/1997 to 12/2004 877 previously untreated Binet A pts were enrolled. 788 pts could be stratified, 471 pts (68,3%) to the low risk (LR), 218 pts (31,6%) to the HR cohort for disease progression. 99 pts were not eligible due to violation of inclusion/exclusion criteria. 104 pts (HRF) were randomized to treatment with fludarabine (fludarabine IV 25 mg/m2/d, day 1–5, every 28 days), 114 pts (HRWW) to “watch and wait”. 30 pts were not eligible for PFS and OS. Analyses on PFS and OS on 188 pts are presented here. Response was defined by NCI-WG criteria (Cheson et al., 1996), progression was defined by slightly modified NCI-WG criteria with regard to the early stage. Results: The median observation time was 45.3 months (95% CI, 3.2–96 mo) for HRF and 40.4 months (95% CI, 6.9–92 mo) for HRWW. The median age in the HRF arm was 61 vs. 62 yrs in the HRWW arm. The HRWW arm contained significantly more male pts (p=0.03). All other parameters used for risk stratification and other characteristics like age, performance state, comorbidity, B symptoms, absolute lymphocyte count, hemoglobine, platelets, lymphadenopathy, splenomegaly or hepatomegaly were not significantly different at time of randomization. Response to fludarabine could be evaluated in 70 pts. The overall response rate was 91%, 11 pts had complete remission (16%), 5 pts had nodular partial remission (PR) (7%), 48 pts (69%) had PR, 3 pts (4%) had stable disease and 3 pts (4%) had progressive disease. Main toxicities (grade 3 or grade 4 CTC) were leukocytopenia and infections. Infections were not significantly higher in the treatment arm (p=0.12). Dose reduction was necessary in 20% of pts due to toxicity. 20 deaths were reported in the HRF arm, 12 deaths were reported in the HRWW arm (p=0.47). Discussion: On an intent-to-treat analysis PFS was significantly longer in the HRF arm in comparison to the HRWW arm (24.2 vs. 15.9 mo, p=0.03). Though the median OS was not yet reached, no significant difference between both groups in OS was assessed (p= 0.47). Conclusion: CLL pts of Binet stage A but with risk features have a median time to progression of 15.9 months. Fludarabine prolongs the PFS, but not the OS in this group of patients.

Abstract Introduction Patients with asymptomatic early Rai or Binet stage chronic lymphocytic leukemia (CLL) do not benefit from mono-chemotherapy. Therefore, clinical observation without treatment (watch&wait; W&W) has been the gold standard for the management of these patients. Chemoimmunotherapy with FCR improves the outcome of patients with advanced CLL, but its efficacy in early stage disease has not been investigated. Several clinical and biological variables identify those patients who have a high risk of an aggressive disease course and who might benefit from early interventions. Consequently, this trial was conducted to test the value of FCR treatment in patients with early stage, high-risk CLL. Methods This report represents the endpoint and safety analysis of a randomized German-French cooperative phase III trial comparing the efficacy of early versus deferred FCR therapy in treatment-naïve Binet stage A CLL patients with a high risk of disease progression. Risk assessment was performed using 4 prognostic markers: Lymphocyte doubling time <12 months, serum thymidine kinase >10 U/L, an unmutated immunoglobulin heavy chain variable region gene (IGHV) status, and presence of unfavorable cytogenetics (del11q, del17p, trisomy 12) by fluorescence-in-situ hybridization. Presence of at least 2 versus less than 2 of these factors defined “high-risk” versus “low-risk” CLL. High-risk CLL patients were further randomized to receive either 6 cycles FCR (HR-FCR) or to be followed by a W&W strategy (HR-W&W). Patients with low-risk CLL were observed only (LR-W&W). Results Between 2005 and 2010, a total of 824 patients was enrolled, 423 patients in 69 centers of the German CLL Study Group and 401 patients in 25 centers of the French Cooperative Group on CLL. The diagnosis of CLL needed to be established no longer than 12 months prior to enrollment and patients were required to present with previously untreated stage Binet A CLL at the time of inclusion. Overall, 800 patients (97.1%) were stratified, 201 of them categorized as high-risk CLL (25.1%). There was no significant difference between high-risk patients from the two study groups regarding common baseline characteristics (e.g., age, sex, comorbidity, immunophenotype) and the distribution of risk factors used for stratification. 100 out of 201 high-risk patients were randomized to receive FCR therapy (HR-FCR), while 101 patients were allocated to the HR-W&W arm. 18 out of 100 patients (18%) withdrew consent for FCR therapy before treatment was started. 71 (86.6%) of 82 treated patients completed ≥4 cycles. The most common of 228 CTC grade III/IV adverse events reported within 12 months after treatment initiation were hematotoxicity (73.2% of patients) and infections (19.5% of patients). Three patients (3.7%) developed fatal CTC grade V infections (2 septic bacteremias, 1 of them with pulmonary aspergillosis; 1 encephalitis). Out of 79 patients available for response assessment until month 12 after treatment start, 76 showed a complete or partial remission (ORR 96.2%), 2 patients had stable disease (2.5%) and 1 patient had progressed (1.3%). After a median follow up of 46 months (range 0-88 months), HR-FCR patients demonstrated a significantly improved event-free survival (EFS) compared to HR-W&W patients (median EFS not reached versus 24.5 months, respectively, P<0.0001, Fig. 1). Overall survival was not significantly different between HR-FCR and HR-W&W with 181 high-risk patients (90%) being alive at last follow up. Both, HR-FCR and HR-W&W patients exhibited a significant shorter event-free and overall survival than LR-W&W patients, demonstrating an efficient prognostic segregation of patients by the risk assessment used for this trial (analysis based on the German LR-W&W cohort only, complete German-French LR-W&W data will be presented at the meeting). Conclusion This is the first randomized phase III trial investigating the efficacy of FCR chemoimmunotherapy in early stage CLL. So far, the study has revealed two major results: 1. A combination of clinical and biological factors can be used to identify early stage CLL patients who experience a rapid disease progression with unfavorable outcome, 2. FCR chemoimmunotherapy substantially improves event-free survival in early stage high-risk CLL. Disclosures: Langerbeins: Roche: travel grants Other.

1087 Background: Paclitaxel/carboplatin combinations are highly active in metastatic breast cancer (MBC). We conducted a randomized, phase III, non-inferiority trial comparing paclitaxel/carboplatin (TP) with paclitaxel/epirubicin (TE) as first-line therapy for MBC. Progression-free survival (PFS) was the primary efficacy endpoint. Secondary endpoints included response rate, overall survival, tolerability, and quality of life (QoL). Methods: From June 2009 to January 2015, 231 patients were randomly assigned, 115 of whom were randomized to TP and 116 to TE. Baseline characteristics were relatively well-balanced in the two treatments. Results: After a median follow-up of 29 months, no significant difference was observed between the two treatments in objective response rate (ORR) (38.3% vs. 39.7%, respectively). Both the progression-free survival (p=0.158) and overall survival (p=0.369) were very similar between the two treatments. Both regimens were well tolerated. The main toxicities were myelosuppression, gastrointestinal reactions, and alopecia. TP showed higher grades 3–4 alopecia and higher nausea (p<0.05). TE showed higher incidence of myelosuppression than TP (p<0.05) (Table). Those patients whose epirubicin cumulative dose was more than 1000 mg/m2 did not suffer worse cardiotoxicity. Conclusions: Our study suggests that TP arm is an effective therapeutic alternative for patients with MBC, especially in those previously exposed to epirubicin in the adjuvant setting. TP has some advantages, such as less cost and less side effects (myelosuppression and fatigue). Clinical trial information: NCT02207361. [Table: see text]

488 Background: Progression-free survival (PFS) is often used as a primary endpoint in oncology clinical trials as a surrogate for overall survival. Traditionally, the Response Evaluation Criteria in Solid Tumors (RECIST) have defined disease progression as a significant increase in the size of tumor lesions and the development of new lesions. However, some patients starting immunotherapy have shown initial increased size of tumor lesions followed by tumor regression, due to the unique mechanism of action of immunotherapies. This initial “pseudo-progression” could be classified inaccurately as disease progression, as evidenced by benefit from the treatment beyond progression approach ( JAMA Oncol 2016). The phase III CheckMate 025 trial of nivolumab versus everolimus in patients with advanced renal cell carcinoma allowed treatment beyond progression if there was investigator-assessed clinical benefit and tolerability. The purpose of our study was to test if treatment duration for an immunotherapy was different from RECIST-defined PFS, and as such, could potentially explain the apparent lack of correlation between RECIST progression and overall survival shown in CheckMate 025. Methods: Using 1-year data from CheckMate 025, Kaplan–Meier methodology was used to estimate the median duration of PFS and time to treatment discontinuation (TTD). Stratified log-rank test was used to assess the difference in treatments. Results: For all patients, the median PFS with nivolumab was 4.6 months (95% CI, 3.7–5.4 months) and median TTD was 6.2 months (95% CI, 5.6–7.7 months). For everolimus, the median PFS was 4.4 months (95% CI, 3.7–5.5 months) and median TTD was 3.9 months (95% CI, 3.7–4.6 months). Conclusions: Patients in CheckMate 025 had significantly longer survival with nivolumab than with everolimus, but with similar PFS. Our analysis demonstrated that while PFS was similar to TTD with everolimus, there was a significant difference between the 2 measures for nivolumab, suggesting that RECIST-defined PFS may not be the proper endpoint to define progression for immunotherapies. Further evaluation of the association of TTD and other immune-related progression endpoints with overall survival is warranted. Clinical trial information: NCT01668784.

2002 Background: This study sought to update the predictive significance of the three WHO-defined molecular glioma subgroups ( IDHwt, IDHmt/noncodel, and IDHmt/codel) in the subset of specimens available for analysis in NRG Oncology/RTOG 9802, a phase III trial of high-risk low-grade gliomas (LGGs) treated with radiation (RT) with and without PCV after biopsy/surgical resection. Notably, this is the first phase III study to evaluate the predictive value of the WHO subgroups in LGGs using prospectively-collected, well-annotated long-term overall survival data, in a post-hoc analysis. Methods: IDH1/2 mutation status was determined by immunohistochemistry and/or next-generation sequencing. 1p/19q status was determined by Oncoscan and/or 450K methylation data. Treatment effects on overall survival (OS) and progression-free survival (PFS) by marker status were determined by the Cox proportional hazard model and tested using the log-rank test in a secondary and exploratory analysis. Results: Of all the randomized eligible high-risk G2 patients (N = 251) in NRG Oncology/RTOG 9802, 106(42%) patients had tissue available with sufficient quality DNA for profiling. Of these, 80(75%) were IDHmut; 43(41%) were IDHmut/non-co-deleted, 37(35%) were IDHmut/co-deleted, and 26(24%) were IDHwt. Upon univariate analyses, no significant difference in either PFS or OS was observed with the addition of PCV in the IDHwt subgroup. Both the IDHmut/non-co-deleted and IDHmut/co-deleted subgroups were significantly correlated with longer PFS (HR = 0.32; p = 0.003; HR = 0.13; p < 0.001) and OS (HR = 0.38; p = 0.013; HR = 0.21; p = 0.029) in the RT plus PCV arm, respectively. Conclusions: Our analyses suggest that both IDHmut/non-co-deleted and IDHmut/co-deleted subgroups received benefit from treatment with PCV although sample size is limited and analyses are post-hoc. Our results also support the notion that IDHwt high-risk LGG patients do not benefit from the addition of PCV to RT. Funding: U10CA180868, U10CA180822, and U24CA196067.

Purpose In 1996, we initiated the French multicenter phase III randomized trial to compare the effect on disease-free survival (DFS) of concurrent versus sequential chemotherapy (CT) and radiotherapy (RT) after breast-conserving surgery for stages I and II breast cancer. This report presents the clinical results with a median follow-up of 60 months. Patients and Methods Between February 1996 and April 2000, 716 patients were entered onto this trial. Adjuvant treatment began within 6 weeks after surgery. Sequential treatment of CT administered first followed by RT was compared with concurrent treatment of CT administered with RT. The CT regimen consisted of mitoxantrone (12 mg/m2), fluorouracil (500 mg/m2), and cyclophosphamide (500 mg/m2) on day 1, and it was repeated every 21 days for six courses. RT was delivered to the breast and, when indicated, to the regional lymphatics. Results There was no statistically significant difference in treatment in the 5-year DFS (80% in both groups; P = .83), locoregional recurrence-free survival (LRFS; 92% in sequential v 95% in concurrent; P = .76), metastasis-free survival (87% in sequential v 84% in concurrent; P = .55), or overall survival (90% in sequential v 91% in concurrent; P = .76). Nevertheless, in the node-positive subgroup, the 5-year LRFS was statistically better in the concurrent arm (97% in concurrent v 91% in sequential; P = .02), corresponding to a risk of locoregional recurrence decreased by 39% (hazard ratio, 0.61; 95% CI, 0.38 to 0.93). Conclusion This treatment protocol remains an appealing clinical option for many women with operable breast cancer at a high risk of recurrence. Combination treatments with new drugs for breast cancer are warranted.

PURPOSE: Nasopharyngeal carcinoma (NPC) is highly sensitive to both radiotherapy (RT) and chemotherapy. This randomized phase III trial compared concurrent cisplatin-RT (CRT) with RT alone in patients with locoregionally advanced NPC. PATIENTS AND METHODS: Patients with Ho’s N2 or N3 stage or N1 stage with nodal size ≥ 4 cm were randomized to receive cisplatin 40 mg/m2 weekly up to 8 weeks concurrently with radical RT (CRT) or RT alone. The primary end point was progression-free survival (PFS). RESULTS: Three hundred fifty eligible patients were randomized. Baseline patient characteristics were comparable in both arms. There were significantly more toxicities, including mucositis, myelosuppression, and weight loss in the CRT arm. There were no treatment-related deaths in the CRT arm, and one patient died during treatment in the RT-alone arm. At a median follow-up of 2.71 years, the 2-year PFS was 76% in the CRT arm and 69% in the RT-alone arm (P = .10) with a hazards ratio of 1.367 (95% confidence interval [CI], 0.93 to 2.00). The treatment effect had a significant covariate interaction with tumor stage, and a subgroup analysis demonstrated a highly significant difference in favor of the CRT arm in Ho’s stage T3 (P = .0075) with a hazards ratio of 2.328 (95% CI, 1.26 to 4.28). For T3 stage, the time to first distant failure was statistically significantly different in favor of the CRT arm (P = .016). CONCLUSION: Concurrent CRT is well tolerated in patients with advanced NPC in endemic areas. Although PFS was not significantly different between the concurrent CRT arm and the RT-alone arm in the overall comparison, PFS was significantly prolonged in patients with advanced tumor and node stages.

5507 Background: Despite resection and postoperative irradiation high-risk (3 or more involved lymph nodes, extra-capsular disease and/or microscopically involved mucosal margins of resection) squamous cell carcinomas (SCCAs) of the head and neck frequently recur in the tumor bed. Postoperatively radiochemotherapy (RCT) with cis-Platin (CDDP)/5-FU versus radiotherapy (RT) alone was compared in a randomized trial. Methods: Between 5/97 and 12/04, 440 patients who had high-risk SCCAs of the head and neck were enrolled in this prospectively randomized phase III trial. Following resection and neck dissection, 214 patients were randomly assigned to RT (66 Gy/33 Fx/6.6 weeks) and 226 patients to identical RT plus CDDP (20 mg/m2 on day 1–5, 29–33) and 5-FU (600 mg/m2 on day 1–5, 29–33). Results: The 5 year local-regional control rate is 72.2 ± 3.7% following RT and 88.6 ± 2.4% for the RCT group (p = 0.00259; 5-year progression free survival 50.1 ± 4.0% and 62.4 ± 4.4% (p = 0.024) and 5-year overall survival 48.6 ± 4.4% vs. 58.1 ± 4.6% (p = 0.11). There was no difference in the 5 year incidence of distant metastases (19.3 ± 3.6% vs 25.5 ± 4.6%; p = 0.45). The incidence of grade 3+ acute toxicity was higher during RCT: mucositis 12.6% vs. 20.8% (p = 0.04), leucopenia 0% vs. 4.4% (p = 0.007). Conclusions: Acute toxicity is increased to an acceptable level by RCT. Postoperative RCT compared to RT improves locoregional control and progression free survival; thus survival as a trend is improved by 10% after 5 years. Supported by Deutsche Krebshilfe 70–2140.

Abstract Background. Cervical cancer is the second most frequently diagnosed cancer and the third leading cause of cancer death for women in developing countries. Radical hysterectomy with bilateral pelvic lymph node dissection is usually preferred for patients of stage IB1-IIA2. Currently, image examinations have certain limitations in diagnose of lymph node metastasis and their detection accuracies are not satisfactory. Only the pathological examination after removal of the suspected metastatic lymph nodes during surgery can conclusively identify the presence of metastasis. If there is a positive result of lymphatic metastasis, there is no clear guideline whether to complete a radical surgery, or to only conduct a systematic lymphadenectomy, followed with adjuvant Concurrent Chemoradiotherapy (CCRT). This retrospective study aimed to compare the efficacy and safety of the two treatment modalities. Methods. 49 stage IB1-IIA2 cervical cancer patients with lymphatic metastasis confirmed by systemic pelvic and para-aortic lymph node dissection from 2007 to 2018 were reviewed. The patients were treated with either primary chemoradiation or radical hysterectomy followed by adjuvant chemoradiation after lymphadenectomy. Survival states and adverse events of the two treatments were compared. Results. Median follow-up time was 45 (range 11-119 months) months. In non-radical surgery group, 1 patient (1/15, 6.7%) relapsed and died, while in radical surgery group, 7 patients (7/27, 25.9%) relapsed and 5 (5/27, 18.5%) died. Significant difference was found in the mean progression-free survival between the two groups, which was 69(95%CI 49.118-88.882) months in non-radical surgery group and 44(95%CI 35.857-52.143) months in radical surgery group (p＜0.01). There was significant difference in three-year progression-free survival(86%vs.71%, p＜0.01). Grade 3-4 toxicity was comparable between the two groups (26.7% vs. 25.9%, p=0.958). Conclusion. For stage IB1-IIA2 cervical cancer patients with positive lymph node, primary chemoradiation after pelvic and para-aortic lymphadenectomy seems to have better survival outcomes compared with radical hysterectomy by laparoscopy plus chemoradiation in the retrospective study with limited cases. Evidence from a randomized controlled study is in need to confirm the optimal treatment for early stage node-positive cervical cancer.

Prospective Phase

Fifty-one of 189 evaluable patients from three prospective phase-II trials evaluating a sequential targeted treatment (clinicaltrials.gov NCT02345863, NCT02401503, NCT02689141) had high-risk CLL with a deletion 17p, TP53 mutation or both. Twenty-seven patients started treatment with bendamustine debulking prior to the induction and maintenance treatment, which was ibrutinib/ofatumumab (IO) in 21 patients, ibrutinib/obinutuzumab (IG) in 13 and venetoclax/obinutuzumab (AG) in 17 patients. The primary endpoint was the overall response rate after eight months of induction treatment, which were 81%, 100% and 94% for IO, IG and AG, respectively. Minimal residual disease (MRD) was undetectable in peripheral blood (uMRD; &lt;10-4 by flow cytometry) in 0%, 23% and 82% of patients, respectively. Median progression free survival (PFS) was 45 months. Seventeen patients discontinued maintenance treatment due to undetectable MRD, nine of them progressed and two died without progression (median PFS: 28 months after discontinuation of treatment), while six patients remained in remission after a median observation time of 46 (range 6-47) months after discontinuation of treatment. Thus, MRD-guided fix-duration therapies combining obinutuzumab with venetoclax or ibrutinib can induce deep and durable remissions in CLL patients with high-risk genetic lesions, which can persist after treatment discontinuation.

Purpose This study was designed to compare fluorouracil, leucovorin, and oxaliplatin with fluorouracil, leucovorin, and cisplatin in patients with advanced gastric cancer. Patients and Methods Patients with previously untreated advanced adenocarcinoma of the stomach or esophagogastric junction were randomly assigned to receive either fluorouracil 2,600 mg/m2 via 24-hour infusion, leucovorin 200 mg/m2, and oxaliplatin 85 mg/m2 (FLO) every 2 weeks or fluorouracil 2,000 mg/m2 via 24-hour infusion, leucovorin 200 mg/m2 weekly, and cisplatin 50 mg/m2 every 2 weeks (FLP). The primary end point was progression-free survival (PFS). Results Two hundred twenty patients (median age, 64 years; metastatic, 94%) were randomly assigned. FLO was associated with significantly less (any grade) anemia (54% v 72%), nausea (53% v 70%), vomiting (31% v 52%), alopecia (22% v 39%), fatigue (19% v 34%), renal toxicity (11% v 34%), thromboembolic events (0.9% v 7.8%), and serious adverse events related to the treatment (9% v 19%). FLP was associated with significantly less peripheral neuropathy (22% v 63%). There was a trend toward improved median PFS with FLO versus FLP (5.8 v 3.9 months, respectively; P = .077) and no significant difference in median overall survival (10.7 v 8.8 months, respectively). However, in patients older than 65 years (n = 94), treatment with FLO resulted in significantly superior response rates (41.3% v 16.7%; P = .012), time to treatment failure (5.4 v 2.3 months; P < .001), and PFS (6.0 v 3.1 month; P = .029) and an improved OS (13.9 v 7.2 months) as compared with FLP, respectively. Conclusion FLO reduced toxicity as compared with FLP. In older adult patients, FLO also seemed to be associated with improved efficacy.
