EA2197: Optimal Perioperative Therapy For Incidental Gallbladder Cancer (OPT-IN): A Randomized Phase II/III Trial
Primary Objective To determine the difference in overall survival (OS) for patients given neoadjuvant gemcitabine and cisplatin prior to re-resection followed by adjuvant gemcitabine and cisplatin compared to patients who receive only adjuvant gemcitabine and cisplatin after re-resection for incidental gallbladder cancer (IGBC).
Secondary Objectives To compare the incidence of residual disease at the time of re-resection between patients with IGBC who receive perioperative chemotherapy prior to re-resection and those who receive only adjuvant chemotherapy after re-resection.
To assess the clinical effect of preoperative chemotherapy compared to upfront re-resection on resectability among 3 cohorts: all enrolled patients, all patients who undergo staging laparoscopy, and all patients who undergo laparotomy.
To determine the difference in progression-free survival (PFS) for patients with IGBC who receive perioperative chemotherapy prior to and after re-resection compared to patients who receive only adjuvant chemotherapy after re-resection
