Abstract:

Background: Gemcitabine plus cisplatin or S-1 can be used as first-line treatment for advanced or metastatic biliary tract adenocarcinoma. Multiple phase 2 studies found that gemcitabine, oxaliplatin, capecitabine, S-1 were not superior to gemcitabine plus cisplatin. Nab-paclitaxel plus S-1 was effective and well-tolerated in pancreatic cancer. Methods: Patients with pathological confirmed advanced or metastatic biliary tract adenocarcinoma (gallbladder carcinoma, intrahepatic cholangiocarcinoma ICC, extrahepatic cholangiocarcinoma ECC) were treated with Nab-paclitaxel plus S-1(Nab-paclitaxel 120mg/m2, d1 and d8; S-1 80-120mg/d, d1-14; q21d). Patients that received PR or SD (RECIST1.1)after 6 cycles were given S-1 maintenance treatment. The primary endpoint was ORR. The study used Simon’s Two Stage design. Results: From March 2016 to September 2018, we recruited 54 patients, with 27 males (50%). The median age was 58(34-73yrs). As of Dec 31 2018, the median treatment cycle was 4(1-6 cycles). 51 patients were evaluable for efficacy: PR 14(27.5%), SD 22 (DCR=PR+SD: 70.6%), PD 15 (29.4%). The median PFS was 6 months, and the median OS was 13.2 months. The response rate varied in different tumor location: gallbladder carcinoma 53.8% (7/13), ICC 18.2% (6/33), ECC 20% (1/5).Common grade 3/4 AEs were: leucopenia 17 (31.5%), hyperbilirubinemia 5(9.3%), Mucositis 4 (7.4%), neurotoxicity 2 (3.7%), diarrhea 2 (3.7%), omit 1(1.9%), fatigue 1 (1.9%), thrombocytopenia 1 (1.9%), ALT increase 1 (1.9%). Conclusions: Nab-paclitaxel plus S-1 as first line treatment for advanced or metastatic biliary tract adenocarcinoma was effective and well-tolerated, especially for gallbladder carcinoma (ORR 53.8%). This regimen need further exploration. Clinical trial information: NCT03830606
