ABSTRACT
Objective To investigate the diagnosis and the relationship between its clinicopathological characteristics,treatment and the prognosis of primary colorectal lymphoma.Methods The clinical data of 20 primary colorectal lymphoma patients who received operative treatment in the past 34 years in our hospital were retrospectively summarized,and the influence of treatment and each clinicopathological factor on prognosis was assessed.Results Tumor size,lymph node metastasis,invasion of neighboring organs and distant metastasis,and type of operative treatment were significantly related to the survival(P0.05).Conclusions Diagnosis of primary colorectal lymphoma before operation is difficult,and misdiagnosis is common.Operative treatment is the main therapeutic means for colorectal lymphoma.Radical operation combined with chemotherapy can gain a good prognosis.
ABSTRACT
Objective To determine the resectability of recurrent gastric malignant tumor and its clinical value, and to search an effective way to cure recurrent gastric malignant tumor. Methods The clinical data of 18 cases of sucessfully resected local regional recurrent gastric malignant tumor were analysed retropectively. Results In the 18 cases of recurrent malignant gastric tumor, 6 received total gastrectomy and lymphadenectomy, 5 received body and tail pancreatectomy plus splenectomy with lymphadenectomy, 2 got tumor resection in gastric bed, and the other 5 got periceliac tumor resection with lymphadenectomy. Pathology evidence revealed that 14 of them were gastric adenocarcinoma and the other 4 were gastric sarcoma. They were all recovered and got well when discharged. Follow up results revealed that resection of recurrent malignant gastric tumor could survive 16.4 months (7～38 months) averagely.Conclusions Patient's life quality and survival time could be improved if the local regional recurrence was resectable and other subsidiary therapeutic methods were used.
ABSTRACT
Objective To investigate the rational method of treatment of rectal carcinoid and its outcome.Methods The clinical data of 36 cases of rectal carcinoid were retrospectively analysed.Results During a follow-up of 82.6+/-63.4 months,there were no cases with recurrence among the 20 patients with tumor size2cm.Conclusions Tumor diametar can be used to estimate the degree of malignancy of rectal carcinoid.TNM staging is simpler and practical for deciding the method of surgical treatment.
