Background: Selecting proper postoperative adjuvant therapy is of great importance for prolonging overall survival (OS) of patients with biliary tract cancer (BTC). OS is commonly affected by high rate of postoperative recurrence and metastasis.Purpose: The present study aimed to identify the optimal adjuvant therapy for BTC patients.Method: A comprehensive search was carried out on Pubmed, Web of science, and Embase databases to acquire articles regarding BTC therapy approaches. Subsequently, the hazard ratio (HR) and its 95% confidence intervals (CIs) were applied to evaluate the efficacy of different adjuvant therapy regimens. The GemTc (GemTc.0.8-2) and R (R.3.6.0) software were employed to perform statistical analyses.Result: Data from 22 articles, including 14,646 patients, were quantitatively analyzed. The results showed that in terms of 5-year OS, gemcitabine (GEM) was considered as the optimal adjuvant therapy for BTC compared with chemoradiotherapy (CRT; HR = 0.59; 95% CI = 0.34-0.97), observation (OB; HR = 0.49; 95% CI = 0.33-0.73), and radiotherapy (RT; HR = 0.40; 95% CI = 0.22-0.71). Additionally, 5-fluorouracil (5-FU) exhibited improved efficacy compared with RT (HR = 0.52; 95% CI = 0.29-0.91) and OB (HR = 0.63; 95% CI = 0.43-0.92). When the efficacy of 5-FU was compared with that of GEM, the results showed that 5-FU (HR = 1.29) was more effective than GEM. Furthermore, CRT and RT prolonged positive resection margin (R+)-OS (HR = 0.69; 95% CI = 0.49-1.00) and positive lymph node-(N+)-OS (HR = 0.22; 95% CI = 0.074-0.66) in BTC patients. In terms of median recurrence-free survival (RFS) and 1-year OS, the differences were not statistically significant among different therapeutic interventions.Conclusion: The present study suggested that GEM could be used as a first-line adjuvant therapy for resected BTC patients. Additionally, CRT could be the optimal treatment approach for R+ and N+ 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.

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.

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.

Abstract Background Evidence for the efficacy of immunotherapy in biliary tract cancer (BTC) is limited and unsatisfactory. Methods Chinese BTC patients receiving a PD-1 inhibitor with chemotherapy, PD-1 inhibitor monotherapy or chemotherapy alone were retrospectively analyzed. The primary outcome was overall survival (OS). The key secondary outcomes were progression-free survival (PFS) and safety. Patients previously treated with any agent targeting T cell costimulation or immune checkpoints were excluded. Results The study included 77 patients (a PD-1 inhibitor plus chemotherapy, n = 38; PD-1 inhibitor monotherapy, n = 20; chemotherapy alone, n = 19). The median OS was 14.9 months with a PD-1 inhibitor plus chemotherapy, significantly longer than the 4.1 months with PD-1 inhibitor monotherapy (HR 0.37, 95% CI 0.17–0.80, P = 0.001) and the 6.0 months with chemotherapy alone (HR 0.63, 95% CI 0.42–0.94, P = 0.011). The median PFS was 5.1 months with a PD-1 inhibitor plus chemotherapy, significantly longer than the 2.2 months with PD-1 inhibitor monotherapy (HR 0.59, 95% CI 0.31–1.10, P = 0.014) and the 2.4 months with chemotherapy alone (HR 0.61, 95% CI 0.45–0.83, P = 0.003). Grade 3 or 4 treatment-related adverse events were similar between the anti-PD-1 combination group and the chemotherapy alone group (34.2% and 36.8%, respectively). Conclusions Anti-PD-1 therapy plus chemotherapy is an effective and tolerable approach for advanced BTC.

This study is an investigator-initiated randomized phase II trial focusing on the treatment of advanced biliary tract cancer with either oxaliplatin 50 mg/m2 and gemcitabine 1000 mg/m2 on day 1 in a two-week cycle with capecitabine 650 mg/m2 twice-daily continuously or cisplatin 25 mg/m2 and gemcitabine 1000 mg/m2 on day 1 and day 8 in a three-week cycle. One-hundred patients were included. Forty-seven patients received oxaliplatin, gemcitabine, and capecitabine with a median progression-free survival (mPFS) of 5.7 months (95% CI 3.0–7.8) and a median overall survival (mOS) of 8.7 months (95% CI 6.5–11.2). Forty-nine patients received cisplatin and gemcitabine with a mPFS of 7.3 months (95% CI 6.0–8.7) and a mOS of 12.0 months (95% CI 8.3–16.7). This trial confirms a mOS of 12 months with cisplatin and gemcitabine, as found in earlier trials. With a superior tumor control rate of 79% vs. 60% (p = 0.045), a difference in the mPFS of 1.6 months (HR = 0.721, p = 0.1), and a difference in the mOS of 3.3 months (HR = 0.731, p = 0.1), cisplatin and gemcitabine should still be considered the standard first-line treatment for advanced biliary tract cancer.

Abstract Cancer originating in the biliary tract can be classified as bile duct cancer (cholangiocarcinoma), gallbladder cancer, or ampullary cancer. Bile duct cancer is further divided to intrahepatic, perihilar and distal bile duct subtypes according to the anatomical location of the tumor. The biological characteristics of each tumor are heterogeneous. However, because of the rarity of each disease, the efficacy of new drugs has been tested in groups of patients with different biliary tract cancers. In patients with metastatic or recurrent biliary tract cancer, recent randomized clinical trials revealed the non-inferiority of gemcitabine + S-1 and the superiority of gemcitabine + cisplatin + S-1 compared with gemcitabine + cisplatin in terms of overall survival, thereby establishing a new standard treatment. In the field of adjuvant therapy for biliary tract cancer, the British BILCAP (capecitabine compared with observation in resected biliary tract cancer) study revealed longer median overall survival in the capecitabine group than in the observation group in the per-protocol analysis (but not in the intention-to-treat analysis), bringing a shift toward postoperative management. Several other studies of adjuvant therapy are ongoing, and they may lead to reforms in treatment strategy for resectable biliary tract cancer in the future. The use of neoadjuvant therapy for biliary tract cancer is in its infancy, but it is expected to overcome the limitations of adjuvant therapy for this malignancy. In this review, we summarized the evidence available from clinical trials of adjuvant and neoadjuvant therapy for biliary tract cancer and described ongoing clinical trials.

Purpose The purpose of this study was to investigate the clinical outcomes and prognostic factors of concurrent chemoradiotherapy (CCRT) for locally recurrent biliary tract cancer (BTC) after curative surgical resection. Methods We performed a retrospective cohort study of patients with locally recurrent BTC treated with CCRT between October 2004 and December 2013. The study included and analyzed 42 patients with a history of curative-intent surgical resection of confirmed adenocarcinoma originating from the biliary tract. Results The median time to recurrence after surgery was 16.1 months (range, 4.5-77.8 months). Median follow-up after CCRT was 26.9 months (range, 5.2-81.9) with no grade 3 or higher gastrointestinal toxicities. Analysis of the first site of failure showed local progression (LP) developed in 20 patients (47.6%); among these, 16 (38.1%) had isolated LP. The median values were 15.8 months (range, 1.7-81.7) for LP-free survival (LPFS), 10.6 months (range, 1.7 - 81.7) for progression-free survival (PFS) and 41.2 months (range, 5.2-81.9) for overall survival (OS). Multivariate analysis showed that the level of pre-CCRT carbohydrate antigen (CA) 19-9 and the chemotherapy regimen were significant prognostic factors for LPFS and PFS; pT stage was the only significant prognostic factor for OS. Conclusions CCRT for locally recurrent BTC showed promising outcomes as a salvage modality, but LP was still frequent. The pre-CCRT CA 19-9 level and the chemotherapy regimen were prognostic factors for LPFS and PFS.
