RESUMO

OBJECTIVE: Steroid hormone levels, particularly androgens, play an important role in sexual function in premenopausal women, but this relationship is not so well determined after menopause. This study aimed to assess the association between steroid hormone levels and sexual function in postmenopausal women. METHODS: A total of 84 postmenopausal women with intact ovaries, who had never used systemic hormone therapy, were enrolled in a cross-sectional study. Sexual function was assessed using the Female Sexual Function Index (FSFI) questionnaire and serum levels of steroid hormones were quantified by gas chromatography and tandem mass spectrometry. Associations between estradiol, testosterone, dehydroepiandrosterone, androstenedione and FSFI domain scores were evaluated. RESULTS: After adjustment for confounding variables, the analysis revealed a statistically significant association between androstenedione and overall sexual function (ß = 1.23, 95% confidence interval [CI] [0.37; 1.98], p = 0.010), arousal (ß = 0.19, 95% CI [0.02; 0.37], p = 0.034), orgasm (ß = 0.33, 95% CI [0.15; 0.45], p = 0.001) and satisfaction (ß = 0.25, 95% CI [0.11; 0.36], p = 0.001). No associations were found between the other hormones and FSFI domains. CONCLUSION: The main finding of this study is the association of androstenedione with sexual function in postmenopausal women, not verified for other steroid hormones. Further studies are necessary to determine the importance of androstenedione for postmenopausal sexual function.

RESUMO

Estrogen receptor alpha (ERα), that mediates the biologic effects of estrogen in estrogen-sensitive tissues like breast, is genetically polymorphic. To evaluate the association between -397 PvuII (T>C) and -351 XbaI (A>G) restriction fragment length polymorphisms (RFLPs) in intron 1 of ERα gene and susceptibility of breast cancer, we undertook a case-control study in BRCA1 185delAG and 5382insC/BRCA2 6174delT negative Portuguese women. The study population consisted of 107 patients with histological diagnosis of breast cancer and 121 women with no history of breast cancer. Genomic DNA was extracted from blood samples and genotyping analyses were performed by PCR-RFLP. XbaI polymorphism was associated with a significant reduced risk of breast cancer for carriers of the x allele in homozygozity (OR 0.178; 95% CI 0.070-0.456; P<0.001) or heterozigozity (OR 0.223; 95% CI 0.089-0.561; P=0.001). The PvuII polymorphism was associated with a non-significantly reduced risk. The combined analysis of PvuII and XbaI polymorphisms revealed none synergistic effect of the two genotypes, except for simultaneous carriers of pp and xx genotypes, that have a reduced risk of breast cancer (OR 0.226; 95% CI 0.049-1.035; P=0.044). The combination of PvuII and XbaI genotypes into haplotypes showed that carriers of two copies of the px (ppxx) haplotype had a reduced risk of breast cancer (OR 0.405; 95% CI 0.194-0.843; P=0.014), compared with PX (PPXX+PPXx+PpXX+PpXx) haplotypes. PvuII and XbaI polymorphisms were in linkage disequilibrium both in cases (D=0.044, r2=0.049, X2=5.216, P=0.022) and controls (D=0.090, r2=0.139, X2=16.819, P<0.001), but not in the entire sample population analyzed as a whole (D=0.087, r2=0.0076, X2=1.733, P=0.188). In conclusion, in this case-control study we found that ERα gene XbaI polymorphism may modify individual susceptibility for breast cancer in this population.

RESUMO

A 61-year-old woman presented to the emergency room complaining of anterior left thoracic pain and shortness of breath even after minor efforts. Her previous medical history was unremarkable. Pulmonary angiographic tomography showed a moderate bilateral pleural effusion that had collapsed inferior lung lobes, a large pericardial effusion, and several enlarged lymph nodes in the anterior mediastinum. Echocardiogram (ECG) showed a considerable pericardial effusion with some degree of heart function impairment. Pericardiocentesis and thoracocentesis revealed neoplastic cells in both pericardial and pleural fluids. Abdominal and pelvic ultrasound showed a complex cystic mass with a 13-cm diameter located at left adnexal region and another complex cystic tumor with five-cm diameter at right adnexal region, with small amount of peritoneal effusion. Surgical staging was performed. Pathologic diagnosis was primitive left fallopian tube serous adenocarcinoma with peritubal involvement and multiple peritoneal and lymphatic metastases (FIGO Stage IV; TNM pT3c M1). Chemotherapy was initiated. Death occurred 25 months after diagnosis, with secondary dissemination (breast and lung). No recurrence of pericardial effusion was registered after chemotherapy, suggesting a high susceptibility of pericardial metastasis.

RESUMO

OBJECTIVE: To evaluate clinical prognostic factors for local recurrence of vulvar squamous cell carcinoma after primary surgical treatment. STUDY DESIGN: Of 104 patients treated for squamous cell carcinoma of the vulva in an 11-year period (1987-1997) at the Portuguese Cancer Institute, we selected for study 56 patients who meet the following criteria: (1) International Federation of Gynecology and Obstetrics (FIGO) stage Ib-IVa, (2) primary treatment of en bloc radical vulvectomy and bilateral groin dissection, and (3) follow-up reports. Files were retrieved for retrospective analysis. Fifteen patients (26.8%) had local recurrence at the fifth year. At the 24th month, 11 patients had local recurrence, and 31 were in follow-up, without recurrence. We evaluated age at initial diagnosis, date of surgical treatment, tumor size, results of tumor macroscopy, histologic differentiation, groin lymph node status, FIGO stage, resection limits, adjuvant radiotherapy, duration of stay, associated vulvar skin disease, date of detection of recurrence, site/sites of recurrence and follow-up status at the 24th month after surgical treatment between the 11 patients with local recurrence and 31 in follow-up without recurrence. RESULTS: The 11 patients with local recurrence had a significant initial FIGO stage, IVa (P = .049) and a significant association with the number of groin lymph nodes containing metastasis in comparison to the 31 patients without local recurrence. No other statistically compared data were significant. CONCLUSION: These results suggest that vulvar squamous cell carcinoma local recurrence after a primary surgical procedure is related to poor tumor prognostic factors (number of groin nodes containing tumor metastasis and FIGO stage IVa). On multivariate analysis, the presence of metastasis in two or more groin nodes was a powerful factor related to local recurrence. Postoperative radiotherapy to the vulva for such patients with a high risk of local recurrence is advisable.

RESUMO

There are no known biological markers or technologies to predict the natural history of an individual CIN III. The probability of progression is considered greater with the persistence of high-risk human papillomavirus (HPV) infection and age. p53 polymorphism has been associated with cervical carcinogenesis. Hormone-induced cervical cancer is mediated by estrogen receptor (ER) and progesterone receptor (PR). In cervical cancer, increased bcl-2 and Bax immunoreactivity is generally associated with a better prognosis. The purpose of this study was to evaluate the value of HPV 16 and HPV 18 typing and p53 codon polymorphism genotyping by polymerase chain reaction and ER, PR, bcl-2, and Bax expression by immunohistochemistry in predicting the CIN III clinical behavior of CIN III lesions. We studied the expression of these prognostic factors in the CIN III adjacent to squamous cell microinvasive carcinomas of the cervix (MIC) from 29 patients with FIGO stage IA1 cervical cancer and in 25 patients with CIN III and no documented focus of invasion. In the MIC group, only the CIN III was considered at least 2 mm away from the microinvasive complex. The ER, PR, bcl-2, and Bax immunoreactivity was scored as positive (>10% staining cells) and negative (<10% staining cells). No significant difference was observed between MIC and CIN III group concerning HPV infection and p53 polymorphism. The ER, PR, bcl-2, and Bax immunohistochemical expression was stronger and more frequent in the CIN III group. After multivariable analysis, coexpression of ER, PR, and bcl-2 was the only independent factor in defining low risk of progression for CIN III. Our study suggests that coexpression of ER, PR, and bcl-2 may be a useful tool in identifying the CIN III lesions with low risk of progression to cervical cancer.
