ABSTRACT
Objective To study the diagnosis, treatment and prognostic features of primary epididymis leiomyosarcoma.Methods The clinical data of five cases of leiomyosarcoma of the epididymis in Ji 'nan Central Hospital Affiliated to Shandong University were retrospectively reviewed and reviewed literatures to study the diagnosis , treatment and prognostic features .Results Five cases were underwent operation .Pathological examination confirmed the diagnosis of epididymis leiomyosarcoma .The patients were followed up for 3－32 months,2 patients died due to multiple organs metastasis at 14 months and 25 months after operation.One patient died for acute myocardial infarction at 18 months after operation,1 case was lost to follow up,1 case was survival up to today .Conclusion Pathological examination is helpful in diagnosis .The radical inguinal orchiectomy with high ligation of the spermatic cord should be performed early.Primary epididymis leiomyosarcoma has highly aggressive course and prognosis is poor .
ABSTRACT
Objective:To evaluate the clinical value of percutaneous microwave coagulation therapy for peripheral non-small-cell lung cancer. Methods:We evaluated 35 patients with non-small-cell lung cancer who received percutaneous microwave coagulation therapy and 35 patients who received radiotherapy from March 2004 to September 2006;the patients were sex-matched, age-matched, and had the same pathology and clinical staging. Clinical effects were observed and assessed. Survival rate were calculated using the Kaplan-Meier method. The difference in survival rate between the two treatment methods was analyzed using a log-rank test. Results:The 1-year, 3-year, and 5-year survival rates for the microwave coagulation therapy group (71.4%, 40.0%, and 20.0%, respectively) were significantly higher than those for the radiation therapy (51.4%, 22.9%, and 11.4%, respectively) (P<0.05). Conclusion:Percutaneous microwave coagulation therapy is a minimally invasive, safe, and effective alternative for patients with peripheral non-small-cell lung cancer who cannot undergo routine surgery because of poor heart and lung function or fear of surgical trauma.
ABSTRACT
Objective To evaluate the clinical effects,CT features and side-effects of percutaneous microwave coagulation therapy(PMCT) in the treatment of peripheral lung cancer.Methods CT-guided PMCT was applied to 16 cases of peripheral lung cancer from August 2003 to October 2004 in this hospital.Pathological or cytological findings showed 9 cases of squamous carcinoma and 7 cases of adenocarcinoma.A needle microwave antenna was applied into the tumor percutaneously under CT guidance.In each emission of microwave,the tumor was ablated with a 2 450 Hz microwave coagulation output of 65~75 W for 3~5 min.According to the size and shape of the tumor,single or multiple ablation emission was selected.Results The operation time was(15~60) min(mean,35 min).Complete remission(CR) was achieved in 1 case,partial remission(PR) in 4 cases,and no changes(NC) in 11.Follow-up observations in the 16 cases for 3~15 months(mean,9.5 months) found 2 cases of tumor metastasis and 1 case of death.Conclusions Percutaneous microwave coagulation therapy is a safe,micro-invasive,and effective treatment for the management of peripheral lung cancer.
