A prospective feasibility study of one-year administration of adjuvant S-1 therapy for resected biliary tract cancer in a multi-institutional trial (Tokyo Study Group for Biliary Cancer: TOSBIC01)

Abstract Background: Although surgery is the definitive curative treatment for biliary tract cancer (BTC), outcomes after surgery alone have not been satisfactory. Adjuvant therapy with S-1 may improve survival in patients with BTC. This study examined the safety and efficacy of 1 year adjuvant S-1 therapy for BTC in a multi-institutional trial.Methods: The inclusion criteria were as follows: histologically proven BTC, ECOG performance status 0 or 1, R0 or R1 surgery performed, cancer classified as Stage IB to III. Within 10 weeks post-surgery, a 42-day cycle of treatment with S-1 (80 mg/m2/day orally twice daily on days 1–28 of each cycle) was initiated and continued up to 1 year post surgery. The primary endpoint was adjuvant therapy completion rate. The secondary endpoints were toxicities, disease-free survival (DFS) and overall survival (OS).Results: Overall, 46 patients met the inclusion criteria of whom 19 had extrahepatic cholangiocarcinoma, 10 had gallbladder carcinoma, 9 had ampullary carcinoma, and 8 had intrahepatic cholangiocarcinoma. Overall, 25 patients completed adjuvant chemotherapy, with a 54.3% completion rate while the completion rate without recurrence during the 1 year administration was 62.5%. Seven patients (15%) experienced adverse events (grade 3/4). The median number of courses administered was 7.5. Thirteen patients needed dose reduction or temporal therapy withdrawal. OS and DFS rates at 1/2 years were 91.2/80.0% and 84.3/77.2%, respectively. Among patients who were administered S-1 more than 3 courses, only one case discontinued due to adverse events.Conclusions: One-year administration of adjuvant S-1 therapy for resected BTC was feasible and may be a promising treatment for those with resected BTC. Now, a randomized trial to determine the optimal duration of S-1 is ongoing.Trial registration: UMIN-CTR, UMIN000009029.

225 Background: No standard post-surgery adjuvant treatment is currently recommended in localized biliary tract cancer (BTC). Gemcitabine combined with platinum is the standard chemotherapy for advanced BTC. The aim of this phase III randomized trial was to assess whether GEMOX would increase relapse-free survival (RFS) while maintaining health-related quality of life (HrQoL). Methods: We performed a multicenter randomized phase III trial. Patients were randomized, within 3 months of R0 or R1 resection of a localized BTC (intra-hepatic, perihilar, extra-hepatic cholangiocarcinoma or gallbladder cancer), to receive either GEMOX 85 for 12 cycles (Experimental Arm A) or surveillance (Standard Arm B). Co-primary objectives were RFS and HrQoL. 190 patients and 126 RFS events were required to show an increase of median RFS from 18 to 30 months. Results: Between July 2009 and February 2014, 196 patients were included in 33 French centers. Baseline characteristics were balanced, with similar primary sites, R0 resection rates were 86.2% (Arm A) vs 87.9% (Arm B), lymph node invasion present in 37.2% vs 36.4%. In Arm A, a median of 12 cycles was delivered (mean: 9.3, range: 0-12). Maximal grade of adverse events were grade 3 in 57.5% vs 22.2%, and grade 4 in 17.0% vs 9.1%. During treatment one patient died in each arm. The main grade ≥ 3 adverse events in the year following inclusion were peripheral neuropathy (50.0% vs 1.1%), and neutropenia (22.3% vs 0%). Median follow-up was 44.3 months, with 54 and 64 RFS events in arms A vs B. There was no significant difference in RFS between the arms (log-rank p = 0.31), with a hazard ratio of 0.83 [95% CI: 0.58-1.19], p = 0.31 (futility boundaries were crossed). Median RFS was 30.4 [95% CI: 15.4-45.8] vs 22.0 months [95%CI: 13.6-38.3] in arms A & B respectively, and 4-years RFS was 39.3% [95%CI: 28.4%-50.0%] vs 33.2% [95%CI: 23.1-43.7%]. Global Health HrQoL scores were not different at 12 months (70.8 vs 83.3, p = 0.18) and at 24 months (75.0 vs 83.3, p = 0.50). Conclusions: Adjuvant chemotherapy in BTC with GEMOX was feasible and associated with expected toxicities and no deterioration of HrQoL. There was no significant difference in RFS between GEMOX and surveillance. Clinical trial information: NCT01313377.

Biliary tract cancers (BTC) are a disease entity comprising diverse epithelial tumors, which are categorized according to their anatomical location as intrahepatic (iCCA), perihilar (pCCA), distal (dCCA) cholangiocarcinomas, and gallbladder carcinomas (GBC), with distinct epidemiology, biology, and prognosis. Complete surgical resection is the mainstay in operable BTC as it is the only potentially curative treatment option. Nevertheless, even after curative (R0) resection, the 5-year survival rate ranges between 20 and 40% and the disease free survival rates (DFS) is approximately 48–65% after one year and 23–35% after three years without adjuvant treatment. Improvements in adjuvant chemotherapy have improved the DFS, but the role of adjuvant radiotherapy is unclear. On the other hand, more than 50% of the patients present with unresectable disease at the time of diagnosis, which limits the prognosis to a few months without treatment. Herein, we review the role of radiotherapy in the treatment of cholangiocarcinoma in the curative and palliative setting.

Abstract Background No standard treatment is available for advanced biliary tract cancer (BTC) after first-line therapy with gemcitabine plus cisplatin (GEMCIS). The objective of this study was to evaluate safety and anti-tumour activity of fluorouracil, leucovorin, irinotecan plus oxaliplatin (FOLFIRINOX) as salvage treatment in patients with previously treated advanced BTC. Methods In this two-stage phase 2 study, patients with advanced BTC who had disease progression or unacceptable toxicity after ≥3 cycles of GEMCIS were eligible. Primary endpoints were safety and efficacy (defined as objective response rate, ORR). In stage one, ten patients were treated with FOLFIRINOX every 2 weeks. In stage two, an additional 20 patients were enrolled at a starting dose as defined in stage one, provided that in stage ≥1 objective response or ≥2 stable diseases were observed and ≤3 patients had serious adverse events (SAEs) within the first 6 weeks of treatment. Secondary endpoints were progression-free survival (PFS) and overall survival (OS). Results Forty patients were screened for eligibility and 30 patients were enrolled. In stage one, one patient had a partial response and five patients had stable disease. One patient had a SAE during the first 6 weeks of treatment, and five patients required a dose reduction due to adverse events. The most common grade 3–4 adverse events in stage one were neutropaenia, mucositis and diarrhoea. Stage two was initiated with FOLFIRINOX in an adapted dose. In stage two, grade 3–4 neutropaenia, diarrhoea, nausea and vomiting were the most common adverse events. The ORR, median PFS and OS in all patients were 10%, 6.2 and 10.7 months, respectively. Conclusions In patients with advanced BTC who progressed after or were intolerant to GEMCIS, FOLFIRINOX can be administered safely and could be considered as an option for salvage treatment in these patients.

345 Background: Resection of biliary tract cancer, employing pancreatoduodenectomy and major hepatectomy, is highly aggressive. Thus, postoperative gemcitabine cannot be administered employing a routine dosage protocol. We theorized that a 3-weekly protocol (days 1 and 8, every 3 weeks) of gemcitabine as adjuvant chemotherapy would be superior to the usually administered 4-weekly protocol (days 1, 8, and 15 every 4 weeks). Methods: The outcomes of 6 cycles of the 4-weekly protocol and 9 cycles of the 3-weekly protocol were compared in a prospective randomized clinical setting. The primary endpoint was the treatment completion rate, while secondary endpoints were adverse events and recurrence-free survival. Results: We enrolled a total of 27 patients. Only two patients (14%) on the 4-weekly protocol and three (23%) on the 3-weekly protocol (p=0.8099) completed treatment with no omissions and/or dose modifications. Most of the remaining patients (70%) experienced grade 3/4 neutropenia. Relative dose intensities were 72% and 78%, respectively, with the 4-weekly and 3-weekly protocols. Recurrence-free survival rates did not differ significantly between the two protocols. Conclusions: Contrary to our hypothesis, the 3-weekly protocol did not produce superior results in terms of completion, adverse events or recurrence-free survival rates as compared to the standard 4-week protocol.

Incidence And Mortality

4589 Background: Both incidence and mortality of biliary tract cancer (BTC) are increasing, and BTCs are characterized by poor prognosis and limited antitumoral treatments. There is no well-received regimen as the non-first-line treatment in patients with advanced BTCs, leading to the urgency of umbrella-setting personalized therapies according to genomic alterations. Methods: We performed genomic sequencing in a total of 803 BTCs, including 160 patients with whole-exome sequencing and 643 patients with hybrid capture–based comprehensive genomic profiling. Our molecular tumor board developed precise targeted therapies for patients with actionable targets. Results: Overall, the median tumor mutation burden was 3.0 (IQR: 0.8-6.1) Mut/Mb, with 10.5% patients of hypermutated BTCs. The most frequently mutated genes included TP53 (51%), KRAS (23%), ARID1A (16%) and SMAD4 (11%). The most common genes with significantly amplified oncogenes were CCND1 (6.97%), MET (6.72%) and MDM2 (6.6%), while the frequently deleted tumor-suppressor genes are CDKN2A (5.73%) and CDKN2B (5.35%). The mutational map of BTCs highlighted pathways of receptor-tyrosine kinase (RTK)/RAS and p53 signaling were frequently altered. Somatic truncating mutations of mismatch repair genes were identified in 6.1% (49/803) of patients, and germline pathogenic mutations in DNA damage response genes occurred in 8% (64/803) of BTCs. In addition, we demonstrate the amplified chromosomal focal at 7q31.2 was an oncogenic factor and it independently predicts both disease-free survival and overall survival of BTC patients. When molecular screening was linked to targeted therapies, 25.4% (204/803) of patients could match biomarker-assigned drug treatment (BADT). The frequent actionable biomarkers included amplifications of ERBB2 and MET, FGFR2/3 fusions and IDH1 mutations. For 46 patients with refractory BTCs received BADT, the objective response rate was 26.1%, with a median progression-free survival (mPFS) of 5.0 (95%CI: 3.5-6.5) months, and 56.8% patients achieved a ≥1.3 ratio of PFS2/PFS1. 4 of 6 (67%) patients with high microsatellite instability (MSI-H) BTCs had a responsive status after immunotherapy of PD1 inhibitor, confirming that MSI-H status was a robust biomarker of anti-PD1 treatments. Conclusions: Our study established the largest cohort in Chinese BTC patients to investigate the tumor mutational profiling and its translational clinical applications.
