Participants undergo re-resection (including partial liver resection and portal lymph node dissection). Participants then receive capecitabine PO BID on days 1-14. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.

Participants receive cisplatin IV over 1 hour and gemcitabine IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Within 10 weeks of chemotherapy, participants undergo re-resection (including partial liver resection and portal lymph node dissection). Participants then receive capecitabine PO BID on days 1-14. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.

This phase III trial studies how well chemotherapy before and after surgery works in treating participants with gallbladder cancer that can be removed by surgery. Drugs used in chemotherapy, such as cisplatin, gemcitabine, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before and after surgery may kill more tumor cells.

PRIMARY OBJECTIVE:

I. To determine the difference in overall survival (OS) at 3 years for patients with incidental gallbladder cancer (IGBC) who receive neoadjuvant gemcitabine hydrochloride (gemcitabine) and cisplatin (gem/cis) prior to reoperation followed by adjuvant capecitabine compared to patients who receive only adjuvant capecitabine after reoperation.

SECONDARY OBJECTIVES:

I. To determine the difference in recurrence-free survival (RFS) at 1 year for patients with IGBC who receive perioperative chemotherapy prior to and after re-operation compared to patients who receive only adjuvant chemotherapy after reoperation.

II. To assess the clinical effect of perioperative chemotherapy compared to only adjuvant chemotherapy after reoperation on resectability among 3 cohorts: all enrolled patients, all patients who undergo staging laparoscopy, and all patients who undergo laparotomy.

III. To compare the incidence of residual disease at the time of re-resection between patients who receive perioperative chemotherapy and those who receive only adjuvant chemotherapy.

OUTLINE: Participants are randomized to 1 of 2 arms.

ARM I: Participants undergo re-resection (including partial liver resection and portal lymph node dissection) after incidental diagnosis of gallbladder cancer. Participants then receive capecitabine orally (PO) twice daily (BID) on days 1-14. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Participants receive cisplatin intravenously (IV) over 1 hour and gemcitabine IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Within 10 weeks of chemotherapy, participants undergo re-resection (including partial liver resection and portal lymph node dissection). Participants then receive capecitabine PO BID on days 1-14. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, participants are followed up periodically for up to 3 years.

Chemotherapy Before & After Surgery in Patients With Resectable Gallbladder Cancer

Perioperative Chemotherapy Prior To and After Reoperation for Incidental Gallbladder Cancer - An International, Randomized Phase III Trial

Overall survival (OS) is defined as time from randomization to death from any cause.

Recurrence-free survival (RFS) at one year, defined as time from surgery to first observed disease recurrence or death from any cause, among only patients who undergo complete, curative-intent re-resection. Disease recurrence will be based on findings from surveillance cross-sectional imaging of the chest, abdomen, and pelvis (CT or MRI, and any other additional imaging necessary to confirm recurrence). Patients who do not undergo reoperation or re-resection, have incomplete resections (R2), or who have gross evidence of distant metastases and/or T4 disease will be excluded from the RFS analysis

Overall resectability rate is defined as the proportion of patients who successfully undergo a re-resection versus all enrolled patients. Patients who do not undergo reoperation or re-resection, have incomplete resections (R2), or who have gross evidence of distant metastases and/or T4 disease will be considered as unresectable for resectability analyses.

Resectability rate at diagnostic laparoscopy is defined as the proportion of patients who successfully undergo a re-resection versus all patients who undergo staging laparoscopy. Patients who do not undergo reoperation or re-resection, have incomplete resections (R2), or who have gross evidence of distant metastases and/or T4 disease will be considered as unresectable for resectability analyses.

Resectability rate at laparotomy is defined as the proportion of patients who successfully undergo a re-resection versus all patients who undergo laparotomy. Patients who do not undergo reoperation or re-resection, have incomplete resections (R2), or who have gross evidence of distant metastases and/or T4 disease will be considered as unresectable for resectability analyses.

Incidence of residual disease after or at the time of re-resection is defined as the presence of either microscopic or gross malignancy based on pathologic analysis.
