METHODS: Medical records of the diagnosis, surgery, and follow-up of 56 patients with anorectal melanoma who underwent surgery between 1975 and 2008 were retrospectively reviewed. The factors predictive for the survival rate of these patients were identified using multivariate analysis. RESULTS: The 5-year survival rate of the 56 patients with anorectal melanoma was 20%, 36 patients underwent abdominoperineal resection (APR) and 20 patients underwent wide local excision (WLE). The rates of local recurrence of the APR and WLE groups were 16.13% (5/36) and 68.75% (13/20), (P = 0.001), and the median survival time was 22 mo and 21 mo, respectively (P = 0.481). Univariate survival analysis demonstrated that the number of tumor and the depth of invasion had significant effects on the survival (P < 0.05). Multivariate analysis showed that the number of tumor [P = 0.017, 95% confidence interval (CI) = 1.273-11.075] and the depth of invasion (P = 0.015, 95% CI = 1.249-7.591) were independent prognostic factors influencing the survival rate. CONCLUSION: Complete or R0 resection is the first choice of treatment for anorectal melanoma, prognosis is poor regardless of surgical approach, and early diagnosis is the key to improved survival rate for patients with anorectal melanoma.展开更多

METHODS: A retrospective study was conducted among newly-diagnosed cholangiocarcinoma patients from January 2009 to December 2011 who underwent curative resection in Srinakarind Hospital (a 1000-bed university hospital). Two hundred and sixty-three cholangiocarcinoma patients with good performance were enrolled. These patients had pathological reports with clear margins or microscopic margins. Prognostic factors which included clinical factors, serum liver function test as well as serum tumor makers at presentation,tumor data, and receiving adjuvant chemotherapy were determined by uniand multivariate analysis. RESULTS: The median overall survival time was 17 mo (95%CI: 13.2-20.7); and 1-, 2-, and 3year survival rates were 65.5%, 45.2% and 35.4%. Serum albumin levels, serum carcinoembryonic antigen (CEA) levels, staging classifications by American Joint Committee on cancer, pathological tumor staging, lymph node metastases, tumor grading, surgical margin status, and if adjuvant chemotherapy was administered, were shown to be significant prognostic factors of resectable cholangiocarcinoma by univariate analysis. Multivariate analysis, however, established that only abnormal serum CEA [hazard ratio (HR) 1.68; P = 0.027] and lymph node metastases (HR 2.27; P = 0.007) were significantly associated with a decrease in overall survival, while adjuvant chemotherapy (HR 0.71; P = 0.067) and surgical margin negative (HR 0.72; P = 0.094) tended to improve survival time. CONCLUSION: Serum CEA and lymph node metastases which were associated with advanced stage tumors become strong negative prognostic factors in cholangiocarcinoma.展开更多

All patients were followed for three years, and their postoperative complications, survival, and factors that impacted their survival were analyzed.RESULTS The total incidence of postoperative complications was 45.61%, and the incidence of pleural effusion was the highest at 28.07%. There were no correlations between the 2-year and 3-year survival rates and sex, age, and Hbs Ag of the patients(P >0.05). In terms of pathological parameters, the 2-year and 3-year survival rates were significantly different according to the presence of a tumor capsule, degree of liver cirrhosis, satellite or focal lesions, hepatic vein thrombosis, portal vein tumor thrombus, and intraoperative blood loss(P < 0.05).CONCLUSIONThe effectiveness of surgical resection for complex hepatocellular carcinoma may be affected by factors such as the presence of a tumor capsule, cirrhosis degree,satellite or focal lesions, hepatic vein embolization, portal vein tumor thrombus,and intraoperative blood loss. Therefore, these factors should be controlled and prevented during surgery to help improve patient survival after surgery.展开更多

The early stage lesions (Tis, Tl) were assigned as a separate group. The results of these groups were compared.Results The resectability for esophageal and gastric cardiac carcinoma was 94.0% and 84.4% respectively, and the overall resectability was 91.3% . The resectabih'ty for groups A, B, C and the early stage group was 82.1% , 85.1% , 90.2% and 100% , respectively. The overall operative mortality was 1.8%, it was 4.4% for group A, 1.6% for group B, and 0.5% for group C. The overall 5-year survival was 31.6% . The 5-year survival for groups A, B, C and the early stage group was 27.0% , 29.1%, 32.0% and 92.6%, respectively . Among the 3 temporal groups, differences were observed in terms of lesion stage, location and size, surgery with or without combined therapy and postoperative complications.Conclusion Best results were achieved in the early cases, with a resectability of 100% and a 5-year survival of 92.6% . The indications for surgical treatment were extended with increased resectability and decreased mortality. Subtotal esophagectomy combined with cervical esophagogastrostomy was advocated as the procedure of first choice for esophageal carcinoma in attempt to diminish the chance of recurrence, and to achieve better outcomes by using combined therapy for patients with e" stage b! lesion.展开更多

Methods： forty-five patients with cancer of the cardia and esophagogastric junction underwent surgical resection. Of them, 29 were treated using proximal gastrectomy and 16 total gastrectomy. The 3-year and 5-year survival rate and the postoperative complication rate and mortality rate were followed up and compared between the two groups. Results： The 3-year and 5-year survival rates of group PG were 44.8% and 20.7%, of group TG were 37.5% and 18.8%, respectively, and the differences were not statistically significant （X^2= 3.84, P 〉 0.05; X^2= 3.89, P 〉 0.05）. The postoperative complication and mortality rate of group PG were 13.7% and 6.8%, of group TG was all 6%, respectively. Conclusion： Proximal and total gastrectomy treatment effects can not significantly influence the prognosis of patients in progressive stage of cancer of cardia and esophagogastric junction.展开更多
