Surgical treatment of Siewert II adenocarcinoma of the esophagogastric junction / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the outcomes after surgical treatment of esophagogastric junction carcinoma (EGJC).</p><p><b>METHODS</b>One hundred and eighty-five patients with EGJC undergoing surgery from October 2000 to September 2006 at the Cancer Hospital of Shantou University were reviewed retrospectively. The clinical outcomes were compared between transthoracic and transabdominal approach.</p><p><b>RESULTS</b>Of the 185 patients, 133 underwent operation via transthoracic approach and 52 via transabdominal approach. The postoperative complication rates were 10.5%(14/133) and 11.5%(6/52) and the 1-, 3-, 5-year overall survival rates were 83.9%, 44.5%, 32.9% and 86.0%, 38.0%, 30.0% in transthoracic and transabdominal groups respectively, and the difference were not statistically significant (both P>0.05).</p><p><b>CONCLUSION</b>Surgical approach should be individualized for EGCJ.</p>

Long-term results of 84 surgically treated patients with extrahepatic bile duct carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>Extrahepatic bile duct carcinoma is a rare but dismal malignacy. This study is conducted to show retrospective review and analysis of the correlation between the prognosis and different treatment modalities.</p><p><b>METHODS</b>The data of 84 such patients treated by different modalities from January, 1992 to July, 2000 were retrospectively reviewed and analyzed using SPSS 10.0 statistical package. The survivals were estimated by the Kaplan-Meier method and the difference among groups was tested by the log-rank test. The prognostic factors were determined by Cox multivariate analysis.</p><p><b>RESULTS</b>Of the 84 patients, 33 had complete resection, 19 palliative resection, 12 exploration alone, and the remaining 20 were treated by chemotherapy and/or radiotherapy. The mean follow-up time was 592 days. The overall 5-year survival rate was 13.1%. The 1-, 3- and 5-year survival rate following complete resection was 76.8%, 52.6% and 30.5% respectively, which was significantly higher than those of palliative surgery or chemotherapy/radiotherapy (P < 0.01). Multivariate analysis revealed that lymph node status (P = 0), histopathological grade (P = 0.001) and distant metastasis (P = 0.002) were significant high risk factors.</p><p><b>CONCLUSION</b>The prognosis of extrahepatic bile duct carcinoma remains poor even after complete resection as shown to have a 5-year survival of 30.5%. More effective adjuvant therapy is needed. Extended resection may be helpful in improving the prognosis for carefully selected patients. Early diagnosis and early treatment is still the key to improve the long-term survival of extrahepatic bile duct carcinoma.</p>

The long-term results of managements in 98 cases of gallbladder carcinomas / 中华外科杂志

<p><b>OBJECTIVE</b>Carcinoma of the gallbladder is an uncommon, but patients with the disease are associated with a dismal prognosis. The purpose of this study was to analyze the characters, prognostic factors of gallbladder carcinoma and investigate the measures of diagnosis and treatment.</p><p><b>METHODS</b>98 patients admitted into our hospital from January 1992 to July 2000 were followed up, with a mean follow-up time of 478 days (1 - 2,280 days). All statistical analyses were performed with SPSS10.0 statistical package. Survival curves were estimated by the Kaplan-Meier method and differences among groups were tested by the log-rank test. The Cox multivariate analysis was performed to determine prognostic factors on survival.</p><p><b>RESULTS</b>Among 98 patients, 31 with radical resection, 29 with palliative resection, 18 with exploration and 20 with chemo- and/or radiotherapy, The overall 5-year survival rate of the gallbladder carcinoma was 6.67%, The 1-, 3-, and 5-year survival rate following radical resection for gallbladder cancer was 77.29%, 34.37%, 21.48% respectively, The survival rate in radical resection group was remarkably higher than that of the others (P < 0.01). Multivariate analysis revealed that tumor, node, metastases (TNM) stage and therapeutic interventions had significantly higher risk ratios for gallbladder cancer.</p><p><b>CONCLUSIONS</b>With careful patient selection, aggressive resection may help to improve the prognosis, although the disease with ominous reputation. Resection alone is inadequate for a significant improvement in survival, so there is a need to evaluate more effective adjuvant therapy in the form of radiotherapy or newer chemotherapeutic agents. Emphasis to improve the long-term survival should be pay on early diagnosis and early management.</p>
