A Case of Intussusception of the Cecum and Appendix Due to Endometriosis Mistaken as a Cecal Tumor / 대한산부인과학회잡지

We report a case of intussusception of the cecum and appendix arising in pericecal endometriosis that are mistaken as a cecal tumor preoperatively. At the other OBGY clinic, the 1st lapalotomy was performed for management of leiomyoma but pelvic organs were adhesion severely and palpation mass in the cecum and appendix. The patient was transfer to our hospital for evaluation and treatment of mass. We investigated to intestine closely and diagnosis was cecal tumor colonoscopically. Total hystrectomy and iliocecectomy was performed successfully and discovered intussusception of the cecum and appendix due to endometriosis mistaken as a cecal tumor in operative field. Postoperatively, this case was diagnosed in pericecal endometriosis histologically.

A Clinicopathologic Study of 31 Cases with Ovarian Malignant Germ Cell Tumors / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study was to review the clinicopathologic features, recurrent rate, survival rate and controversable issues in the treatment of the ovarian malignant germ cell tumors. PATIENTS AND METHODS: From August, 1991 to November, 1998 thirty-one patients with malignant germ cell tumors of the ovary treated in the department of obstetrics and gynecology, Kosin University Medical college, were eligible and assessable. Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and results of follow up were reviewed retrospectively. RESULTS: The patients with malignant germ cell tumor constituted 6.37% of all ovarian malignancies during this period. Histologic subtypes were 8 dysgerminoma(25.8%), 7 endodermal sinus tumor(22.6%), 10 immature teratoma(32.3%), 3 mixed germ cell tumor(9.7%), 3 choriocarcinoma(9.7%). The age of the patients ranged from 10 to 40 years (mean +/-S.D.; 24.26 +/- 7.51). The most common symptom was abdominal pain(38.7%). Most had stageI(18 cases, 58.0%) or stageIII(5 cases, 16.2%) diseases. All patients underwent surgery as the initial treatment, and nine patients received more than one operation. Postoperative adjuvant chemotherapeutic regimens were VAC, VBP, EP, BEP, EMA, and EMA CO. The mean follow up duration was 26.0(+/- S.D.; +/- 20.3) months. The 2-year and 5-year survival rate were 91.97%(+/- S.E.; +/- 0.05) and 86.86%(+/- S.E.; +/- 0.07).

Expression of bcl-2 and p53 Protein in Invasive Cervical Cancer / 대한부인종양콜포스코피학회잡지

Recently, the bcl-2 and p53 protein have been recognized as important factors that is contributed to programmed cell death. The objective of this study was to evaluate the prognostic significance of bcl-2 and p53 protein expression in uterine cervical carcinoma. The expression of bcl-2 and p53 in 59 cases of uterine cervical carcinoma (stage IB to IIB) were surgically treated from January 1993 to June 1994. The expression of bcl-2 and p53 was examined by immunohistochemical method using formalin fixed paraffin embedded tissue specimens. The 48 cases were squamous cell carcinoma and 11 cases were adenocarcinoma. The results were as follows: 1. The expression rate of bcl-2 protein was 28.8%(17/59) and there was no significant correlaltion between the expression of bcl-2 protein and the clinicopathologic parameters (histologic type, grade, FIGO stage, cervical invasion depth, lymph node metastasis, parametrial invasion, tumor size, neoadjuvant chemotherapy response, recurrence, survival). 2. The expression rate of p53 protein was 32.2%(19/59) and there was no significant correlation between expression of p53 protein and the clinicopathologic parameters. 3. There was significant correlation between and expression of bcl-2 and p53 protein (P 0.05). In conclusion, bcl-2 and p53 protein are thought to be possible factors in the carcinogenesis of uterine cervical carcinoma and correlate with progression of it. But further study will be required to clarify the role of bcl-2 and p53 in carcinogenesis of the uterine cervix.

c-erb B2 and p53 Overexpression in Presence of Human Papilloma Virus Type 16/18 Infection in Carcinomas of the Uterine Cervix: Genesis and Clinicopathologic Analysis / 대한산부인과학회잡지

The 43 cases of the primary uterine cervical carcinoma were analyzed for HPV type 16/18 infection and also analyzed for overexpression of p53 and c-erb B2 oncoprotein to evaluate theirs oncogenic and clinicopathologic relationships. HPV type 16/18 infection was examined by polymerase chain reaction(PCR) and the overexpression of p53 and c-erb B2 protein by using immunohistochemical method. The results were as follow: 1. The HPV infection rate in primary uterine cervical carcinomas was 83.7% respectively.The standard clinicopathologic characteristics(age, histologic type, koilocytosis, mitosis, clinical stage, tumor size, cervical invasion depth, lymph node metastasis, parametrial invasion) were nat significantly correlated with HPV type 16/18 infectivity. 2. The overexpression rate of p53 protein was 72.1% and there was no Significant correlation between expression of p53 protein and the Clinicopathologic characteristics. 3. The overexpression of c-erb B2 oncoprotein was 44.2% and there was no significant correlation between the overexpression of c-erb B2 oncoprotein and the clinicopathologic characteristics. 4. There was no significant correlation between HPV type 16/18 infection and overexpression of p53 and c-erb B2 oncoprotein.
