RESUMO

Combination chemotherapy consisting of bleomycin, ifosfamide, and ciplatin (BIP) is recognized as one of the most effective chemotherapies for uterine cervical cancer. However, there have been no reports that evaluate concurrent use of radiation with BIP. The objective of this study was to evaluate the toxicity and response of the combination of BIP concurrent with radiation in patients with squamous cell carcinoma of the uterine cervix. Eligibility criteria included patients who underwent radical hysterectomy (Type III hysterectomy) as a primary treatment and revealed lymph node metastases or deep myometrial invasion (stage IB and IIA) and patients who were previously untreated (stage IIB-IV). All of the patients had biopsy-proven squamous cell carcinoma of the uterine cervix. The patients received three courses of BIP chemoradiation, and the response and toxicity were evaluated. From January 2000 to December 2003, 30 patients met study eligibility criteria. All but three patients completed 3 courses of planned chemotherapy. The frequency of severe (grade 3 and 4) toxicity was as follows: anemia, 46.7%; neutrocytopenia, 73.3%; thrombocytopenia, 16.7%; and nausea and vomiting, 23.3%. Among 30 patients, 22 cases were evaluated for response. Complete response was achieved in 16 (72.7%) of patients, with a response rate of 90.9%. In conclusion, BIP chemoradiation seems to be superior to previously reported chemoradiation regimens, and has a potential as an optimal combination chemotherapy concurrent with radiation.

RESUMO

PURPOSE: Intratumoral metabolism and synthesis of estrogens are considered to play important roles in the pathogenesis and/or development of human endometrial carcinoma. Steroid sulfatase hydrolyzes biologically inactive estrogen sulfates to active estrogens, whereas estrogen sulfotransferase sulfonates estrogens to estrogen sulfates. However, the status of steroid sulfatase and/or estrogen sulfotransferase in human endometrial carcinoma has not been examined. EXPERIMENTAL DESIGN: We first examined the expression of steroid sulfatase and estrogen sulfotransferase in 6 normal endometrium and 76 endometrial carcinoma using immunohistochemistry to elucidate the possible involvement of steroid sulfatase and estrogen sulfotransferase. We then evaluated the enzymatic activity and the semiquantitative analysis of mRNA using reverse transcription-PCR in 21 endometrial carcinomas. We correlated these findings with various clinicopathological parameters including the expression of aromatase, 17beta-hydroxysteroid dehydrogenase type 1 and type 2. RESULTS: Steroid sulfatase and estrogen sulfotransferase immunoreactivity was detected in 65 of 76 (86%) and 22 of 76 (29%) cases, respectively. Results of immunoreactivity for steroid sulfatase and estrogen sulfotransferase were significantly correlated with those of enzymatic activity and semiquantitative analysis of mRNA. No significant correlations were detected among the expression of the enzymes involved in intratumoral estrogen metabolism. There was a significant correlation between steroid sulfatase/estrogen sulfotransferase ratio and clinical outcomes of the patients. However, there were no significant differences between steroid sulfatase or estrogen sulfotransferase and estrogen receptor, progesterone receptor, Ki67, histologic grade, or clinical outcomes of the patients. CONCLUSIONS: Results of our study demonstrated that increased steroid sulfatase and decreased estrogen sulfotransferase expression in human endometrial carcinomas may result in increased availability of biologically active estrogens and may be related to estrogen-dependent biological features of carcinoma.

RESUMO

BACKGROUND: In the present study, we conducted a multicenter retrospective analysis to elucidate the prognostic significance of second-look laparotomy (SLL) in early-stage epithelial ovarian cancer that was confirmed by complete surgical exploration. METHODS: In July 2001, 12 Japanese institutions received questionnaires regarding patients with early-stage epithelial ovarian cancer and SLL. Eligibility criteria included patients with stage I or II epithelial ovarian cancer who were surgically diagnosed between January 1988 and December 1997. Data were collected regarding age, performance status, tumor histologic subtype, stage, preoperative carbohydrate antigen (CA) 125 level, results of SLL if performed, recurrence, disease-free survival, and overall survival. Survival analyses and comparisons were performed by univariate methods. RESULTS: There were 87 patients who met the eligibility criteria. There were no significant differences in the backgrounds of patients who had had SLL ( n = 30) and the non-SLL group ( n = 57). Of the 30 SLL-group patients, 28 had negative SLL findings and 2 had positive findings. Six and 5 patients in the SLL group and the non-SLL group, respectively, had recurrence ( P = 0.177), and 4 patients in the SLL group had a recurrence after "negative" SLL findings. There was no significant difference between the two groups for either overall ( P = 0.73) or disease-free survival ( P = 0.273). On univariate analysis, only clear-cell histology was associated with a poor prognosis in early-stage epithelial ovarian cancer ( P = 0.031). CONCLUSION: SLL is not beneficial for early-stage epithelial ovarian cancer. More favorable outcomes will be achieved for early-stage patients with the improvement of treatment for clear-cell adenocarcinoma.
