ABSTRACT
Objective To explore surgical management of bilateral thyroid papillary carcinoma. Methods The clinical data of 55 patients with bilateral thyroid papillary carcinoma were analyzed retrospectively. Among the 55 patients, total thyroidectomy was performed in 52 cases, total affected lobectomy plus isthmus and opposite near total lobectomy thyroidectomy was performed in 3 cases. Results Among the cases of bilateral functional neck lymph node dissection ,5 cases were all of bilateral neck lymph node metastasis, the positive rate was 100.0%(5/5);, among the cases of unilateral functional neck lymph node dissection,9 cases were found neck lymph node metastasis,the positive rate was 81.8%(9/11); among the cases of bilateral central region lymph node dissection, 1 case was of central region lymph node metastasis, the positive rate was 25.0% (1/4); among the cases of unilateral central region lymph node dissection, 14 cases were of central region lymph node metastasis, the positive rate was 66.7%(14/21). Fifty-three cases were tumor free survival, 2 cases accompanied distant metastasis also gained good effect Conclusions Total thyroidectomy should be performed for bilateral thyroid papillary carcinoma because of its characteristics of multiple tumors. It is considered that whether the neck lymph node dissection should be done depends on the stage of the tumor.
ABSTRACT
Objective To study the clinical characteristics of hereditary nonpolyposis colorectal cancer (HNPCC). WT5”HZMethods Ten kindreds of HNPCC in South Zhejiang area were analyzed. ResultsWT5”BZ Among the 10 families, 27 persons had colorectal cancer with age ranging from 19 to 71(average 45 3 years),74 percent of cases being diagnosed before the age of 50. The total of the colorectal cancer foci in 27 cases were 37, 40 percent of focis located proximal to splenic flexure, 30 percent of cases had multiple primary colorectal cancer, among which 14 8 percent of cases had synchronous multiple primary colorectal cancer, 18 5 percent of cases had metachronous multiple primary colorectal cancer. Thirteen cases died during follow-up of 1～23 years, 14 cases were still alive during follow-up of 1～28 years. KG2Conclusion HNPCC has definite charactistics that are of much help to early diagnosis.
ABSTRACT
Objective To investigate the value of surgical biopsy with guidance of indwelling wire through stereotactic puncture in the diagnosis of occult breast cancer (OBC) and the clinical usage. Method Surgical biopsy was performed on 22 patients with suspected nonpalpable breast lesions. ResultsSurgical biopsy, including localization and resection of the lesion, under the guidance of a guide wire was successful with single procedure for all 22 lesions. The accuracy of qualitative diagnosis was 100%. Pathological examination showed malignant in 9 lesions and benign in 13 lesions. ConclusionThe surgical biopsy with the guidance of indwelling wire through stereotactic puncture is valuable technigue for the diagnosis of occult breast lesions.
ABSTRACT
PURPOSE To investigate the clinical value of the T-antigen monoclonal antibody method on screening of large intestinal carcinoma. METHODS The T-antigen monoclonal antibody method and the galactose oxidase method were simultaneously used to detect T-antigen in large intestinal mucus of 207 cases. RESULTS There was not obvious difference in screening value between the T-antigen monoclonal antibody method and the galactose oxidase method, for that they had similar sensitivity (69. 2%, 67. 3%) and specificity (64. 2%, 65. 6%) in diagnosis of large intestinal carcinoma. CONCLUSION The T-antigen monoclonal antibody method was convenient, eligible and valuable on screening of large intestinal carcinoma.
