The Effects of Gonadotropins on the Development of Ovarian Cancer / 대한산부인과학회잡지

OBJECTIVE: We performed immunohistochemistry for the evaluation of follicle stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR) expression in the ovarian tumors and examined the blood level of the gonadotropins in ovarian cancer patients to investigate ovarian carcinogenesis process related to gonadotropins. METHODS: Between January 2002 and July 2003, 25 patients with ovarian tumors were treated in the Hallym University Sacred Heart Hospital. 25 ovarian tumors including 7 borderline tumors, 1 sex cord stromal tumor, 1 germ cell tumor, and 16 carcinomas were examined for FSHR, LHR expression by immunohistochemistry. Serum gonadotropins were collected from 13 cases of 25 ovarian tumors who were not taking hormones at the time of blood collection. RESULTS: Followings are results summarized. 1. Mean FSH levels were lower among cases compared with controls. LH levels were lower among cases than controls, but the difference was not statistically significant. 2. The steady decline of FSHR, LHR expression from borderline tumor (86%, 100%) to carcinoma (56%, 43%) is observed. 3. Patients showing significant gonadotropins receptors expression showed lower serum FSH and LH levels when compared with patients with no detectable gonadotropins receptors. CONCLUSION: The presence of FSHR, LHR in ovarian tumors provide additional evidence supporting the relation of gonadotropins and ovarian carcinogenesis. But, this study did not support the hypothesis that pituitary goandotropins increase the risk of ovarian cancer. The decline of receptor expression from borderline tumors to carcinoma suggests that FSH, LH may be needed in early ovarian cancer development. If further studies of gonadal peptides and gonadotropins are done, we can suggest the cut-off value of gonadotropins on ovarian carcinogenesis.

Efficacy of Loop Electrosurgical Excision Procedure (LEEP) in CIS (Carcinoma in Situ) of Uterine Cervix / 대한산부인과학회잡지

OBJECTIVE: The purpose of this retrospective study is to evaluate the efficacy of Loop Electrosurgical Excision Procedure (LEEP) in the diagnosis and in the treatment of CIS (carcinoma in situ). METHODS: Between Jan. 1999 and Apr. 2000, 94 patients with CIS were treated in the Hallym University Sacred Heart Hospital. Three procedures were performed: cytology, punch biopsy and LEEP (loop electrosurgical excision procedure). And the results of cervical cytology, punch biopsy, phathologic diagnosis of LEEP specimens were evaluated in comparison with the pathologic diagnosis of hysterectomy specimens. RESULTS: Followings are results summarized. 1. The concordance rate of LEEP histology with punch biopsy was 60% (53 cases). In comparison to punch biopsy, the higher LEEP histologic rate was 22% (19 cases), and lower LEEP histologic rate was 18% (16 cases), respectively. 2. 67 patients were diagnosed CIS and among them 58 patients underwent hysterectomy. In histologic comparison between LEEP and hysterectomy, there were on 1 (1.7%) patient who had more advanced diagnosis after operation. 3. 67 patients were diagnosed CIS and among them 58 patients underwent hysterectomy. The residual lesion was identified in 19 of 58 patients (33%). CONCLUSION: LEEP was useful diagnostic tool in CIS. But, in therapeutic efficacy, simple LEEP seems to be incomplete. Therefore, when we use LEEP for CIS as therapeutic tool, additional procedure, such as wide excision or endocervical deep resection may be asked. And careful follow up asked in therapeutic LEEP.
