Gemcitabine–cisplatin (GC) as adjuvant chemotherapy in resected stage II and stage III gallbladder cancers (GBC): a potential way forward
- 147 Downloads
Data on adjuvant chemotherapy with gemcitabine–cisplatin (GC) in resected gallbladder cancers (GBC) are scarce. Patients who underwent upfront curative resection for GBC from 2010 to 2016 were analyzed. Patients with stage II–III GBC treated with adjuvant GC were analyzed. A total of 242 patients were evaluated, of whom 125 patients received GC regimen as adjuvant chemotherapy. The median age was 50 years (range 31–74), majority were female (77.6%), and 37 patients (29.6%) had raised CA 19.9 levels at baseline. One hundred and thirteen patients (90.4%) underwent radical cholecystectomy with R0 resections. Median number of GC administered was 6, with completion rates of 84%. Toxicity data were comprehensively available for 110 patients, with common grade 3 and grade 4 being neutropenia (9.9%), fatigue (7.3%) and febrile neutropenia (3.6%), respectively. With a median follow-up of 36.88 months, 3-year RFS was 60.3%. Patients with stage II (28%; n = 35), stage IIIA (28%; n = 35) and stage IIIB GBC (44%; n = 55) had a 3-year OS of 91.9, 67 and 58.1% (p = 0.001), respectively. Patients with stage II–III GBC undergoing R0 resections receiving adjuvant GC have good tolerance, high completion rates and encouraging outcomes in a non-trial high GBC prevalence scenario.
