Detection of Recurrence with FDG-PET Scan in Patients with Endometrial Cancer / 대한산부인과학회잡지

OBJECTIVE: The aim of this study was to evaluate the feasibility of 2-[18F]-fluoro-2-deoxy-D-glucose-Positron emission tomography (FDG-PET) scan for detecting early recurrence in patients with endometrial cancer who showed no evidence of the disease after primary treatment. METHODS: A total of 14 patients, diagnosed and treated for endometrial cancer with surgery and/or subsequent radiotherapy, were included. Whole-body FDG-PET scanning was performed on 14 patients. PET images were interpreted was suspicious for malignancy in areas of localized FDG uptake compared to the surrounding tissues. computed tomography (CT) or magnetic resonance imaging (MRI) and/or fine needle biopsy were performed to evaluate positive FDG uptakes, and all patients were closely followed up at least for 6 months. RESULTS: Of the 14 patients, 2 recurrences were detected by FDG-PET scan. One of these two patients had increased FDG uptake in abdomen, which was negative on CT, and was confirmed to be recurrent 3 month later on follow-up CT. The other patient had a single focus of hypermetabolic activity in right upper quadrant of abdomen, which was correspondent to 5 cm sized hypodense mass along the right anterior segment of the liver on CT scan, and was confirmed to have adenocarcinoma cell on a needle biopsy. CONCLUSION: These preliminary data demonstrate the feasibility of FDG-PET imaging in detection of early recurrence in patients with endometrial cancer. Further prospective evaluation of FDG-PET in larger numbers of patients with endometrial cancer is warranted to more precisely define its accuracy.

A Case of Adenoid Basal Carcinoma of the Uterine Cervix / 대한산부인과학회잡지

Adenoid basal carcinoma of the uterine cervix is rare tumors that have often been regarded as a single entity. 14 cases with adenoid basal carcinoma of the uterine cervix have been reported in the literature. We experienced a case of 36-year female with adenoid basal carcinoma of the uterine cervix. We report this case with a brief review of the literature.

A Case of Spontaneous Pneumothorax During Chemotherapy for Metastatic Choriocarcinoma / 대한산부인과학회잡지

Spontaneous pneumothorax is a rare complication of pulmonary metastatic disease, most often following chemotherapy for osteogenic sarcomas, primary lung cancer or malignant germ cell tumors. Intensive chemotherapy may theoretically increase the risk of pneumothorax in patients with manifest or occult lung metastases by inducing rapid lysis of the tumor tissue and by interfering with repair processes. We present a case of patient with spontaneous pneumothorax after the introduction of chemotherapy for metastatic choriocarcinoma and review the literature and discuss the possible pathophysiologic mechanisms.

Paclitaxel-Cisplatin regimen as First-Line Chemotherapy after Cytoreductive Surgery in Patients with Epithelial Ovarian Cancer / 대한산부인과학회잡지

OBJECTIVE: The purpose of this retrospective study is to assess the efficacy and toxicity of paclitaxel/cisplatin as first-line chemotherapy after cytoreductive surgery in patients with epithelial ovarian cancer. MATERIAL & METHODS: From November 1999 to April 2001, 31 patients with histologically-proven epithelial ovarian cancer not previously treated with chemotherapy entered the study. FIGO stage IA or IB and grade 1 or 2 tumors were excluded. A comprehensive staging was performed during initial laparotomy. Paclitaxel was administered at a dose of 135 mg/m2, intravenously with cisplatin (75 mg/m2) every 3 weeks for 6 planned cycles, with prophylactic oral dexamethasone regimen (20 mg b.i.d.). The response of patients was evaluated with tumor markers and CT before and after chemotherapy. Responses and toxicities were defined according to the Gynecologic Oncology Group (GOG) criteria. RESULTS: The overall response rates were 73% (16/22) in patients with residual disease after cytoreductive surgery (complete response, 64%; partial response, 9%). The median survival was 18 months. Grade 3/4 neutropenia and neuropathy (grade 2) were observed in 16 (52%), 12 (39%) patients, respectively. CONCLUSION: The combination of paclitaxel and cisplatin is a well tolerated regimen with significant activity in the treatment of epithelial ovarian carcinoma after surgery.
