    Abstract: e15778 Background: Gemcitabine-based chemotherapy is considered as a standard front-line treatment for patients with advanced pancreatic cancer. Although addition of erlotinib or S-1 to gemcitabine has yielded better outcomes, it has showed just modest improvement in survival. To overcome this limitation, we evaluated the efficacy and safety of the combination of gemcitabine, erlotinib, and S-1 for the treatment of advanced pancreatic cancer. Methods: Chemotherapy-naïve patients with pathologically proven locally advanced, recurrent or metastatic pancreatic adenocarcinoma were assessed for eligibility. Gemcitabine at 1,000 mg/m 2 was administered intravenously on day 1, and 8, erlotinib at 100 mg/day was administered on days 1-21, and S-1 at 60 mg/m 2 was administered on days 1-14 every 21 days and continued to maximum of 8 cycles of treatment. Dose escalation of S-1 to 80 mg/m 2 was permitted from second cycle for pre-defined tolerable patients. Results: Thirty-seven patients (median age 61.5 years) were enrolled. A total of 140 cycles of chemotherapy were administered (median of 3.8; range 1–8 cycles). Toxicities were evaluated in 36 patients, and the responses were evaluated in 32 patients. Major grade 3/4 toxicities included neutropenia (25%), febrile neutropenia (2.8%), fatigue (22.2%), infection (8.3%), vomiting (5.6%), and mucositis (5.6%). The overall response rate was 12.5% [95% confidence interval (CI), 5.1-28.9%] and disease control rate was 71.9% (95% CI, 56.8-86.3%). The median progression-free survival and overall survival were 3.7 months (95% CI, 2.8-4.6 months) and 6.7 months (95% CI, 3.4-9.9 months), respectively. Conclusions: The combination of gemcitabine, erlotinib, and S-1 provided an acceptable toxicity profile and modest clinical benefits in patients with advanced pancreatic cancer. Clinical trial information: NCT01693419.

    Abstract: 2098 Background: Bevacizumab (Bev) and irinotecan combination therapy is effective against recurrent malignant glioma. However, post-Bev treatment and its clinical outcomes are not well investigated. Methods: We identified 103 consecutive recurrent malignant glioma patients who received Bev plus irinotecan at our institutions.Clinical records and magnetic resonance images were reviewed. Response and progression were assessed by RANO criteria. Results: Bev and irinotecan treatment produced response rate of 37.9% (95% CI, 29.1-47.5%). At a median follow-up time of 41 weeks, the median progression-free survival (PFS) was 17.1 weeks (95% CI, 14.3-20.0), and 6-month PFS (6M-PFS) was 27.8% (95% CI, 18.4-37.2). The median overall survival (OS) was 33.4 weeks (95% CI, 27.8-39.1). Response predicted for superior PFS (25.0 weeks vs. 11.0 weeks, p 〈 .001) and OS (45.9 weeks vs. 26.7 weeks, p 〈 .001). A total of 93 patients discontinued Bev treatment and the reasons for discontinuation were: disease progression in 59 (63.4%), toxicities in 4 (4.3%), physician’s decision in 5 (5.4%), patient’s refusal to further treatment in 25 (26.9%). The median OS was 26.7 weeks in 59 patients who discontinued Bev due to disease progression, and 45.7 weeks in 34 patients who discontinued Bev for reasons other than disease progression (p 〈 .001). Among 85 patients who progressed after Bev, 42 (49.4%) received further therapy: chemotherapy in 32 (37.6%), radiotherapy in 9 (10.6%), and surgery in 1 (1.2%). Further chemotherapy regimens included temozolomide (31.2%), ACNU/CDDP (25.0%), Bev reintroduction (18.8%), erlotinib (12.5%), PCV (9.4%), and intrathecal methotrexate (3.1%). The median survival time after Bev failure was 15.6 weeks (95% CI, 13.3-17.8). Patients who received further therapy showed longer median OS (18.6 weeks vs. 12.9 weeks, p 〈 .001). In patients who received chemotherapy, the median PFS and OS was 6.6 weeks and 20.6 weeks, respectively. Conclusions: Prognosis after Bev failure was poor. Proper selection of patients who may benefit from further treatment is warranted.
