Objective To analyze the clinical diagnosis and treatment of recurrent cancer in gastric remnant.Methods Clinical data of 48 patients who underwent surgical re-operation because of recurrent carcinoma within gastric remnant after radical resection of gastric cancer were analyzed retrospectively.Results All 48 cases were recurrent cancer in gastric stump.The time of recurrence was 6-36 months after first radical resection.After reoperation,the mean survival time of 28 patients(58.3%)who underwent radical resection was 40 months;the mean survival time of 20 patients(41.7%)who received palliative treatment was 14.8 months(P

Objective To study the causes of local recurrence,and diagnosis and treatment outcome of recurrent colorectal cancer.Methods The clinical data of 60 patients with recurrent colorectal cancer treated during 10 years in our hospital were analyzed retrospectively.Results Among the 60 cases,40 cases(66.7 %) had recurrence within 2 years after operation.Recurrence in anastomotic stoma,perineum,abdominal incision occurred and in the abdominal cavity and pelvic cavity in 15,10,7 and 20 cases respectively,and liver metastases were found in 8 cases.All patients underwent reoperation including curative surgery for 38 patients and palliative operation for 22 patients.After radical reoperation the 1-,3-,and 5-year survival rate was 93.6 %,48.8 %,and 36.3 %,respectively,and after palliative reoperation was 54.5 %,0 %,and 0 %,respectively.Conclusions Emphasizing the application of no-tumor touch technique,resection of adequate amount of bowel,performing complete lymphadenectomy and removal of micrometastatic lesions are the major measures to prevent recurrence of rectal cancer after operation.Integrative therapy regimens,of which surgical treatment is the major component,should be considered according to the location of recurrence and the clinical staging of the recurrent cases.

According to the advantages and disadvantages of the clinical medical educa-tion of the ordinary specialized subject-to-undergraduate,the traditional teaching method has been improved in two aspects:choosing case and teaching process.It can be conformed that teaching method of case-based learning is very suitable for physiological teaching.It can improve the effective interaction of teachers and students,and enchance the students' abilities of self-study and theory with practice.
