Retrospective analysis of 47 cases with hilar cholangiocarcinoma using T-staging system / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the clinical value of T-staging system for hilar cholangiocarcinoma which was adopted in memorial Sloan-Kettering cancer center of New York.</p><p><b>METHODS</b>The image data of these 47 patients were analyzed retrospectively from December 1997 to December 2002 whose data were according with our demand, and they were staged into three-stage according to the criteria of the T-staging system. The difference of respectability, ratio of tumor-free resection margin and actuarial survival rate were analyzed for different T-staging. And the coincident ratio of three different kinds of imaging methods was also analyzed.</p><p><b>RESULTS</b>Twenty patients had T(1) tumors, twenty three had T(2) tumors and four had T(3) tumors. The resectability of the three stage was 60%, 39% and 0% respectively, and the difference was significant (P = 0.013). The likelihood of achieving tumor-free margin decreased progressively with increasing T stage (P = 0.018). The cumulative 1-year survival rates of T(1), T(2) and T(3) patients were 60%, 39% and 0% respectively, and the cumulative 3-year survival rate was 35%, 9% and 0% respectively, the survival of different stage patients differed markedly (P = 0.0103). The coincident ratio of combined using MRCP and color Doppler-ultrasonography was higher than that of combined using MRCP and B-ultrasonography or combined using CT/SCT and color Doppler-ultrasonography (P = 0.007).</p><p><b>CONCLUSIONS</b>The T-staging system has a better value for preoperative assessment, and can be used to judge resectability and survival of hilar cholangiocarcinoma. It will be helpful to use MRCP and color Doppler-Ultrasonography combined to verdict the coverage of the tumor and the T-staging preoperatively.</p>

Retrospective analysis on 682 cases of liver cancer after surgical treatment / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the factors of long-turn survival of liver cancer after surgical treatment.</p><p><b>METHODS</b>Five hundred and twenty-two cases of liver cancer that received surgical treatment in 14 years were analyzed retrospectively.</p><p><b>RESULTS</b>Comparison between the small liver cancer (< 5 cm) and the greater one (> 10 cm) revealed that the small liver cancer had a higher survival rates than the greater one [3 year (61.25 +/- 4.41)% versus (45.90 +/- 6.98)%; 5 year (53.84 +/- 5.68)% versus (30.21 +/- 10.23)%]. There were same results between single-nodule and two or more than two nodule [3 year (61.86 +/- 3.69)% versus (38.31 +/- 4.97)%; 5 year (55.40 +/- 4.91)% versus (28.01 +/- 6.31)%], between child I and child II or more than II [3 year (60.68 +/- 3.68)% versus (49.88 +/- 4.13)%; 5 year (50.99 +/- 5.10)% versus (36.39 +/- 7.58)%], and between single segmentectomy of the liver and two or more than two segmentectomy [3 year (68.65 +/- 4.95)% versus (49.88 +/- 4.13)%; 5 year (65.38 +/- 5.69)% versus (37.98 +/- 5.70)%].</p><p><b>CONCLUSIONS</b>Small liver cancer, single-nodule, good hepatic function and minor resection were important factors to prolong survival further.</p>
