Neoadjuvant Chemo-radiotherapy [capecitabine (81026), gemcitabine (31995)] ...Study Participants
34A prospective multicentre study which includes patients ≤ 70 years-old diagnosed of unresectable hilar cholangiocarcinoma (hCCA) ≤3cm in radial diameter, without evidence of lymph node or distant metastases. Liver transplantation preceded by neoadjuvant radio-chemotherapy will be performed in this selected group.
The primary endpoint will be overall survival at 1, 3, and 5 years post-transplant. The secondary endpoints will be: 1) recurrence free survival at 1, 3 and 5 years post-transplant; 2) intention-to-treat survival of overall patients included in the study at 1,3 and 5 year; 3) the rate of patients included in the study who are finally transplanted.
A prospective multicentre pilot study which includes patients ≤ 70 years-old diagnosed of unresectable hilar cholangiocarcinoma (hCCA) ≤3cm in radial diameter, without evidence of lymph node or distant metastases.
The number of subjects necessary is 34 patients to achieve a power of 82% with a significance level of 0.05 to detect a 40% difference between the estimated 50% survival of those patients who are transplanted and 10% of those patients with hCCA unresectable who are not transplanted. This corresponds to a hazard ratio of 3.3219. Estimated loss to follow-up of 10% of patients.
RADIOLOGICAL EVALUATION
It will be considered unresectable those lesions Bismuth IV with the following criteria (Jarnagin WR, et al. Ann Surg 2001; 234:507; Memorial Sloan Kettering Cancer Center Hilar Cholangiocarcinoma Classification):
Bilateral extension to second order biliary
Unilateral extension to second-order biliary radicals AND contralateral portal vein involvement OR contralateral hepatic lobar atrophy
Main or bilateral portal vein involvement
Insufficient future liver remnant even after portal embolization
It will be performed the tumoral marker (CA 19.9), multiphase chest-abdomen CT scan, magnetic resonance cholangiopancreatography (MRCP) as well as positon emission tomography (PET)-scan if there is doubts of distant disease and upper endoscopic ultrasound (EUS) in order to rule out any obvious lymph node metastases. A biliary drainage will be placed by percutaneous transhepatic biliary drainage (PTBD) or endoscopic biliary drainage (EBD).
NEOADJUVANT TREATMENT
Patients will receive neoadjuvant radiotherapy (External - 50-54 grays) following by concomitant oral capecitabine (1,330mg/m2).Thereafter, gemcitabine iv (1000mg/m2) plus cisplatin iv will be administered the day 1 and 8 every 21 days until transplant.
A staging laparotomy/laparoscopy is recommended before including the patient in waiting list for transplant to confirm the abscence of extra-hepatic disease, especially peritoneal seeding and lymph nodes involvement.
A score exception will be allowed to optimized the treatment received and to be transplanted during the first 6 months.
LIVER TRANSPLANT AND FOLLOW UP
Regarding liver transplant technique, hepatic artery should be avoided for arterial reconstruction using the splenic artery or an iliac conduit.
Biomarker analyses in the explant specimen will be performed.
The patient will be monitored post-operatively at the clinical, biological and morphological levels every 3 months during the first 2 years and every 6 months thereafter in order to detect any recurrence and in the context of standard clinical care.
Patients will receive neoadjuvant radiotherapy (External - 50-54 grays) following by concomitant oral capecitabine (825mg/m2 bid).Thereafter, gemcitabine iv (1000mg/m2) plus cisplatin iv (25mg/m2) will be administered the day 1 and 8 every 21 days until transplant.
If no spread disease is discovered after neoadjuvant treatment, the patient will be listed for liver transplantation.
Patients with unresectable hilar cholangiocarcinoma (hCCA) ≤3cm in radial diameter, without evidence of lymph node or distant metastases
