Clinical Trial of Adjuvant Chemotherapy Followed by Concurrent Chemoradiotherapy Compared With Adjuvant Chemotherapy Alone in Patients With Gallbladder Carcinoma and Extrahepatic Cholangiocarcinoma

The present study is designed to determine whether adjuvant concurrent chemoradiotherapy improves overall survivals.

The role of adjuvant radiotherapy in gallbladder carcinoma (GBCA) or extrahepatic cholangiocarcinoma (EHCC) is unknown. A retrospective study suggested that chemoradiotherapy provides greater benefit than chemotherapy alone in GBCA patients. SWOG S0809, a phase II study showed that adjuvant chemoradiotherapy has promising efficacy in GBCA or EHCC. The present phase III clinical trial is designed to compare adjuvant concurrent chemoradiotherapy with chemotherapy alone.

Inclusion Criteria:

• The patients with pathologic diagnosis of gallbladder carcinoma (GBCA) or extrahepatic cholangiocarcinoma (EHCC) after radical resection.

• The patients with pathologic stage T2-4 or N1 in R0 resection or positive resection margins (R1).

• Aged 18 to 70 years old, male or female, body condition score generally ECOG 0～2, expected survival ≥ 6 months.

• Subjects were no major organ dysfunction, blood, liver, kidney and heart function was normal, the specific requirements of laboratory indicators:

  • Blood: Absolute neutrophil count > 1.5 × 109 / L, Platelet count > 100 × 109 / L, Hb > 8.0g/dl.
  • Liver function: serum bilirubin less than 1.5 times the upper limit of normal; ALT and AST less than 2.5 times the upper limit of normal.
  • Renal function: creatinine less than 1.5 times the upper limit of normal.

• Patients who can understand the circumstances of this study and signed informed consent.

Exclusion Criteria:

• Pregnancy, breast-feeding patients；
• Patients received prior anticancer therapy for the current malignancy or upper abdominal radiotherapy or chemotherapy at any time.
