RESUMEN

BACKGROUND/AIMS: To evaluate the efficacy of two-stage surgery and multidisciplinary approach, in the treatment of primary colorectal cancer, synchronous with advanced liver metastases. METHODOLOGY: Sixty-two patients who underwent two-stage surgery for advanced metastatic liver disease synchronous with colorectal tumor were studied. In the first-stage surgery, the primary colorectal tumor was resected. Depending on the location of the main tumor mass, ligation and transection of the relevant (right or left) main portal vein branch was done. Subsequently, the metastatic nodules in the contralateral lobe were ablated by microwave therapy. An arterial jet port catheter was also introduced into the hepatic artery via the gastroduodenal artery for locoregional chemoimmunotherapy. Two days after the first-stage surgery locoregional transarterial targeting chemoimmunotherapy was given. The second-stage hemihepatectomy was carried out forty to forty-five days after the initial surgery. As an adjuvant treatment locoregional targeting chemoimmunotherapy was carried out in all patients via the arterial chemoport. RESULTS: Mean survival was 66+/-4 months. There were no operative deaths. CONCLUSIONS: Two-stage liver surgery including, portal vein branch ligation, microwave ablative therapy and transarterial targeting locoregional chemoimmunotherapy is the best treatment for advanced, synchronous metastatic liver disease of colorectal origin. It results in an increase in the overall survival of these patients with good postoperative quality of life, which encourages the hepato-biliary surgeon to venture upon this herculean task thus increasing the resectability rate of the tumor.

RESUMEN

BACKGROUND/AIMS: To evaluate, the early and long-term results of mono-bloc spleno-pancreatic and vascular resection for advanced carcinoma of the head of the pancreas, with portal-mesenteric venous invasion. METHODOLOGY: In a prospective, randomized trial, fifty-six patients with advanced carcinoma of the head of the pancreas with vascular invasion were studied. Patients were randomly divided in two groups A and B. Group A patients underwent an en-bloc spleno-pancreatic and vascular resection. Group B patients underwent a palliative gastro-biliary bypass. Patients in both groups were subjected to adjuvant locoregional chemoimmunotherapy, through an arterial catheter introduced into the superior mesenteric artery via a jejunal arterial branch. RESULTS: The 2- and 5-year survival rates for Group A patients were 81.8% and 18.5%. The respective percentages for disease-free survival were 60.6% and 0%. Two-year survival for group B was nil. CONCLUSIONS: Mono-bloc spleno-pancreaticoduodenectomy and regional vascular resection and reconstruction, with adjuvant locoregional chemoimmunotherapy leads to substantial prolongation of survival and optimization of quality of life.
