To evaluate usefulness of MR in assessment of tumor response to the chemotheraphy, we prospectively studied cases of cervical carcinoma with more then 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were performed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherapy and MR examination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. @ES The results were following. @EN 1) All tumors dectrased in volume (m=80.5%). 2) Five tumors (38.5%) reduced in stage, IB→CIS(1); IIA→CIS(1), IIA→IB(2), IIB→IB(1). 3) Depth of stromal invasion in MRI correlated well with that of histo-pathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessement of tumor response to chemotherapy.

Tamoxifen is a nonsteroidal triphenylethylene delivative that has been widely used in the treatment of breast cancer. tamoxifen is indicated for the adjuvant treatment of breast cancer in women following total mastectomy or segmental mastectomy, breast irradiation and chemotherapy. tamoxifen has been shown to have significant benificial effect in the treatment of breast cancer patient as hormonal therapy. However ,there is mounting evidence that tamoxifen may affect other hormon sensitive organs, including the uterus and ovaries. An increased risk of endometrial polyps, endometrial hyperplasia and adenocarcinoma has been reported in tamoxifen treated women. We have met cases of endometrial polyp and endocervical polyp which were associated with tamoxifen use, after modified radical mastectomy for infilterating ductal carcinoma of breast . So we report these cases with the brief review of literatures.

OBJECTIVES: E-cadherin is a transmembrane protein that is one of the key players involved in cell to cell adhesion. Loss of E-cadherin expression is suggested to promote tumor invasion and distant metastasis in tumor development. Recently, it has been proposed E-cadherin function requires its linkage to the cytoskeleton through catenins. So defects in catenins may cause defective E-cadherin function and promote tumor invasion. We intend to evaluate the expression of E-cadherin and alpha-, beta-, gamma- catenin in tissues of human endometrial carcinoma to analyze the patterns of cell adhesion molecules' expression in endometrial carcinoma and to investigate the relationship between status of cell adhesion molecules and various clinicopathological factors. MATERIALS AND METHODS: The present study investigated the immunohistochemical expression of E-cadherin and alpha-, beta-, gamma- catenin in 33 paraffin embedded formalin fixed tissues of endometrial carcinomas. RESULTS: Aberrant E-cadherin, alpha-, beta-, gamma- catenin expression was observed in 33.3(11 of 33), 27.3(9 of 33), 18.2 (6 of 33), and 51.5(17 of 33) % of the specimens, respectively. Statistically significant correlation was found between aberrant expression of E-cadherin and lymph node metastasis and cell types other than endometrioid adenocarcinoma. Aberrant pattern of gamma- catenin expression also correlated with deep myometrial invasion. But alpha-, beta- catenin expression were not correlated with any clinicopathological parameters. Using Kaplan-Meier curves, abnormal expression of E-cadherin correlated closely with poor survival (p<0.05). CONCLUSION: We revealed aberrant expression of these cell adhesion molecules in part of patients with endometrial carcinoma. Aberrant expression of E-cadherin was correlated with lymph node metastasis and cell types other than endometrioid adenocarcinoma and aberrant expression of gamma-catenin was related with deep myometrial invasion.

Alterations in the expression of genes that control the cell cycle may be of critical importance in tumorigenesis and malignant transformation. The major regulatory events leading to cell proliferation occur in Gl phase of cell cycle, and the deregulated expression of Gl cyclins is related to oncogenesis. Cyclins Dl and E play important roles in the progression of cell through Gl phase of the cell cycle. Amplification and/or overexpression of the cyclin Dl gene and aberrant expression of cyclin E has been described in various forms of human cancer. However, the role of cyclins Dl and E in cervical cancer has been poorly defined. In this study, we examined the expression of cyclins Dl and E by Northern blot technique and the status of human papil- lomavirus(HPV) type 16 and 18 by polymerase chain reaction in 25 cases of cervical carcinoma to explore the relationship between cyclins Dl and E and cervical cancer. We found cyclin Dl expression showed down-regulated expression in cervical cancer but cyclin E expression was increased in cancer group. Other clinicopathological prognostic factors were not correlated with cyclins D1 and E expression. Further study based on larger numbers of cases with correlation of cyclins D1 and E status and survival data will be needed to elucidate the use of cyclin expressions as prognostic factor.
