Background: Gallbladder cancer (GBC) and cholangiocarcinoma (CCA) are rare entities with relatively poor prognoses. We compared treatment outcomes of definitive resection with or without neoadjuvant therapy in GBC and CCA patients. Methods: All non-metastatic GBC and CCA patients at a single institution who underwent definitive resection from 1992-2016 were analyzed. We compared overall survival (OS), locoregional failure (LRF) and distant failure (DF) in patients who received neoadjuvant therapy (chemotherapy and/or radiation) versus those who did not receive neoadjuvant treatment. OS was analyzed using the Kaplan-Meier method and log rank tests. Cox proportional hazard models were used to analyze time to recurrence. Results: Out of 128 patients, 90 had GBC and 38 had CCA, 25 patients (27%) among GBC and 8 patients (21%) with CCA were T3, T4 or node positive. Overall, 52 (58%) GBC and 25 (66%) CCA patients received neoadjuvant treatment, chemotherapy alone 60 patients (47%) or radiation with or without chemotherapy 17 patients (13%). Chemotherapy was single agent in 44 patients (34%) and multiagent in 25 (20%). The median OS for GBC patients was 3.1 years with 2.6 years for no neoadjuvant group and 3.1 years for neoadjuvant group (P=0.6786). Median OS was 2.6 years for CCA patients, 3.6 years for no neoadjuvant therapy versus 2.0 years for neoadjuvant group (P=0.1613). There was a trend towards increased DF in patients with CCA and GBC receiving neoadjuvant therapy: HR 2.74, 95% CI, 0.73-10.3, P=0.14 and 0.92, 95% CI, 0.44-1.93, P=0.82 respectively. The hazard ratio for time to LRF in CCA patients receiving neoadjuvant treatment was 3.17, 95% CI, 0.62-16.31, P=0.16 whereas HR was 0.15, 95% CI, 0.10-1.76, P=0.23 for GBC patients. Among GBC patients, the pattern of first failure was locoregional in 8 (10%) having 3 LRF in neoadjuvant group (2 with chemotherapy, 1 with CRT, 0 with RT alone) as compared to 5 in adjuvant group. Among 28 (35%) patients with DF first, 15 patients received neoadjuvant therapy versus 13 patients in non-neoadjuvant group. In CCA patients, LRF occurred first in 6 patients receiving neoadjuvant treatment (3 with chemotherapy, 1 with CRT, 2 with RT alone) as compared to 2 patients who were treated with non-neoadjuvant CRT. DF was the first site of failure in 9 patients treated with neoadjuvant CRT (8 with chemotherapy, 0 with CRT and 1 with RT alone) as compared to 4 patients without neoadjuvant treatment. Conclusions: In this retrospective data set, a trend towards better survival was seen in adjuvantly treated CCA patients, but not in GBC patients. Recurrence patterns also appear different among the two, which might be attributed to treatment modality used, patient selection or unmeasured factors.
