Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

OBJECTIVE: Because endometriosis is difficult to diagnose and has a high recurrence rate after treatment, a reliable serum marker of endometriosis is necessary. Therefore, the aim of this study is to measure the serum levels of CA125 and CA19-9 in patients with endometriosis before and after treatment and during recurrence, and to assess the usefulness of these levels in the diagnosis, clinical follow up and prediction of recurrence in endometriosis. METHODS: Eighty-eight patients who visited the department of Obstetrics and Gynecology of Ewha Mokdong Hospital from January 1994 to December 1998 and were diagnosed as endometriosis by laparoscopy or explo-laparotomy were enrolled as subjects. A retrospective analysis of serum CA125 and CA19-9 levels at 1 month before and 3 to 6 months after initiation of treatment was done. RESULTS: The serum CA125 and CA19-9 levels of endometriosis group(81.0+/-252.5, 36.6+/-53.4 ; mean+/-2SD, U/ml) before treatment was significantly higher than control group(11.6+/-12.8, 9.4+/-8.6)(p<0.05). Overall sensitivity rate for CA125, CA19-9 levels and both was 53.4%, 42.9% and 64.3% respectively. The sensitivity rate for endometriosis, stage 3 and 4(85.4%, 55.0%) was significantly higher than that, stage 1 and 2(p<0.05). The serum CA125 level in endometriosis group showed a significant increment according to stages(p<0.05) while the serum CA19-9 level showed an increasing trend(p=0.055) and both levels decreased significantly after treatment(p<0.05). The serum CA125 level was also higher at recurrence after treatment(p<0.05). CONCLUSIONS: The serum CA125 and CA19-9 levels are a useful marker for diagnosing severity of disease, monitoring efficacy of treatment and predicting recurrence in endometriosis.

Since the placenta is an organ composed of blood vessels, it is not surprising that its primary neoplasm would be a vascular tumor. Placental tumors, primary or secondary, have been known to interfere with placental function. Chorioangioma(primary tumor of the placenta), which is the most common of them, occurs with an incidence for clinically significant ranges from 1~2.8:10000 births. These tumors are benign and are not usually associated with clinical sequelae unless they are larger than 5cm in long diameter. About one third of the large chorioangiomas may be associated with the maternal and fetal complications. For diagnosis of these lesions, the ultrasonography was used. If the chorioangioma is suspected, color doppler study is informative to confirm the presence of the vascular channels. We reviewed ultrasonograms and clinical records of seven patients who had been diagnosed as placental chrioangioma. The appropriate diagnostic tests and treatment can then be initiated in order to prolong gestation and decrease fetal mortality and morbidity.
