53例肝癌切除术后生存20年以上远期随访分析

Objective To clarify the clinicopathological features of patients surviving≥20 years after resection for hepatoceUular carcinoma(HCC).Methods Between 1961 and 1987, a total of 396 patients underwent hepatic resection for HCC.Of the 396 patients, 53(13.4 %) survived ≥20 years and 343(86.6%) <20 years.A comparative study between the two groups was made.Results By March of 2007, 67.6%(36/53) of the patients were still alive and disease-free while 5.7% (3/53) of them died of tumor recurrence or metastasis, 11.3 % (6/537 died of liver failure, 5.70% (3/537 died of other disease, and 9.4% (5/53) were lost during follow-up.Two patients with intraperitoneal rup-tured HCC survived fro 26.6 years and 38.75 years, respectively.Five young patients got married af-ter resection and have had babies.The longest surviving time was 43 years and 2 months.Reresection for recurrence was done in 9 patients and the mean survival was 26 years and 11 months.Reresection for solitary pulmonary metastasis was performed in 3 patients and the mean survival was 29 years and 2 months.Downstaging followed by resection was performed in 4 patients, mean survival being 22 years and 10 months.In comparison with patients surviving <20 years, those surviving ≥20 years were significantly younger(P<0.05) and had a higher incidence of asymptomatic tumors (P<0.01), lower γ-glutanyl transpeptidase levels (P<0.01), lower incidence of liver cirrhosis (P<0.01) ; high-er percentage of smaller tumors (P<0.01), single nodule tumors (P<0.01) and well encapsulated tumors (P<0.01), lower incidence of tumor emboli in portal vein (P<0.01), better differentiation of tumor cells (P<0.05) and higher curative resection rate (P<0.01).Conclusions Early and cura-tive resection are important for improving long-term survival.Long-term follow-up after resection of HCC is very important, and should continue for the remainder of the patient's life.Reresection for re-currence and metastasis is an important approach to improve prognosis.
