O câncer de ovário é a neoplasia ginecológica mais letal e a sobrevida global é inferior a 40% em cinco anos. Isto ocorre principalmente porque a maioria das pacientes apresenta estadios avançados no momento do diagnóstico. Nestes casos as opções terapêuticas - citorredução e quimioterapia - são apenas parcialmente efetivas. Quando diagnosticado precocemente, por outro lado, a sobrevida em cinco anos é superior a 90% e a cirurgia geralmente é o único tratamento necessário. No entanto, em função da baixa prevalência do câncer de ovário na população, mesmo testes muito específicos produzem altas taxas de resultados falso-positivos e aumento de intervenções cirúrgicas para abordar massas anexiais assintomáticas. Com base nestes fatos, é essencial a busca de métodos e estratégias para se detectar estes tumores em estádios iniciais e ao mesmo tempo evitar intervenções desnecessárias. Neste artigo são revisadas as bases e as possíveis conseqüências de estratégias para a detecção precoce dos tumores ovarianos. São discutidos os principais métodos disponíveis e os resultados de alguns estudos com este objetivo.

PURPOSE: to identify the risk factors associated with the occurrence of surgical site infection (SSI) in surgeries for the treatment of breast cancer. METHODS: the study was conducted on 140 women submitted to treatment of invasive breast cancer during the period from January 2001 to December 2002. SSI was defined as infection occurring up to 30 days after surgery and was related to the operation, according to the standard criteria adopted by the Centers for Disease Control and Prevention (CDC), USA. SSI were considered to be superficial when they involved only the skin and subcutaneous tissue and deep when they involved deep tissues at the site of incision, such as fascia and muscles. The risk factors related to patient were age, hormonal status, staging, body mass index (BMI) and hemoglobin, and the factors related to surgery were type of operation, time of hospitalization, duration of surgery, and formation of seroma and hematoma. Data concerning numerical nonparametric variables were analyzed by the Mann-Whitney test and quantitative variables were analyzed by the Fisher exact test. RESULTS: of the 140 patients studied, 29 (20.7%) presented SSI, which were superficial in 19 (13.6%) and deep in 10 (71%); 111 patients did not present SSI and represented the control group. The risk factors associated with the patient and the disease were locally advanced stage (odds ratio = 27; 95% CI: 1.1-6.5) and obesity, represented by a mean BMI of 32.2 kg/m² in the patients with SSI and a mean BMI of 27.2 kg/m² in the control group (p<0.0001). The factors related to treatment of the disease were the use of neoadjuvant chemotherapy (odds ratio = 2.7 (95% CI: 1.1-6.5), the duration of surgery, whose median value was 165 minutes for the patients who developed the infection and 137 minutes for the control group (p=0.02), and the number of days of use of the postoperative drain, whose median value was 6 days for the patients with SSI and 5 days for the control group (p=0.048). CONCLUSION: on the basis of the identification of risk factors such as advanced stage, neoadjuvant chemotherapy and obesity, preoperative care for these patients should be emphasized. The use of an accurate surgical technique may reduce the impact of other factors such as surgical time and time of use of the drain.

PURPOSE: to evaluate the epidemiologic data and signs of trophoblastic hyperplasia in patients with complete hydatidiform mole (CHM) and to estimate the risk associated with the persistence of the disease. METHODS:: we evaluated 214 patients with CHM submitted to uterine evacuation between 1980 and 2001. The patients were included prospectively. All patients were followed until negative bHCG with weekly clinical evaluation and bHCG quantification. We considered persistence when the patient needed another treatment after uterine evacuation. The risk factors for persistence were evaluated through univariate and multivariate analysis, and the odds ratio (OR) was calculated for each one. RESULTS: among the epidemiologic factors, only negative Rh was significant (OR=2.28). All signs of trophoblastic hyperplasia, represented by uterine size larger than expected, sonographic uterine volume, tecaluteinic cysts, and betaHCG higher than 10(5) were associated with risk for the presistence of the disease. The presence of at least one sign of trophoblastic hyperplasia showed sensitivity of 82% and predictive positive value of 35.1% (OR=4.8). The logistic regression identified larger uterine size than expected and bHCG higher than 10(5) as risk factors for persistence of the gestational trophoblastic disease (OR=4.1 and 5.5, respectively). CONCLUSIONS: the signs of trophoblastic hyperplasia showed good sensitivity to predict persistence of the disease; however, the low predictive positive value does not allow using these criteria to change treatment. It is very important to reinforce the importance of serial betaHCG quantification in these high-risk patients.

PURPOSE: to evaluate the agreement between noninvasive methods - pelvic pain, transvaginal ultrasound and hysterosalpingography - and the gynecologic endoscopy approach for the diagnosis of tuboperitoneal factors responsible for conjugal infertility. METHODS: this is a cross-sectional study including 149 infertile patients who were submitted to clinical evaluation, transvaginal ultrasound, hysterosalpingography, hysteroscopy, and laparoscopy. In the evaluation of pelvic pain, the following complaints were considered to be abnormal: pelvic pain of the dyspareunia type, dysmenorrhea or acyclic pain, and pain upon mobilization of the cervix and palpation of the adnexa. Ultrasonographic examination was considered to be altered when adnexal or uterine morphological changes (hydrosalpinx, myomas or uterine malformations) were detected. Hysterosalpingography was considered to be abnormal in the presence of anatomical tubal changes and unilateral or bilateral obstruction. The agreement between noninvasive methods and endoscopy was evaluated by kappa statistics. RESULTS: the agreements between pelvic pain, transvaginal ultrasound, and hysterosalpingography and the endoscopic approach were 46.3% (kappa=0.092; CI 95%: -0.043 to 0.228), 24% (kappa=-0.052; CI 95%: -0.148 to 0.043), and 46% (kappa=0.092; CI 95%: -0.043 to 0.228), respectively. When at least one alteration detected by noninvasive methods was considered, the agreement with endoscopic approach was 63% (kappa=-0.014; CI 95%: -0.227 to 0.199). Sensitivity and specificity in predicting alterations on endoscopic approach were 39.5 and 80% in the presence of pelvic pain, 14.5 and 72% in the presence of alteration on transvaginal ultrasound, 39.5 and 80% in the presence of alteration on hysterosalpingography, and 70.2 and 28% in the presence of at least one alteration by noninvasive methods. CONCLUSION: there is a poor diagnostic agreement between the several noninvasive methods and endoscopy in the investigation of conjugal infertility secondary to tuboperitoneal factors.

Purpose: to introduce the use of the hemostatic pack, a tampon consisting of compresses tied to the bleeding surface and left in place for 48 to 72 h and which is one of the therapeutic alternatives to be used in this situation. Patients and Methods: we evaluated 3 cases of massive bleeding during surgery, with the exchange, on average, of 1.4 blood volumes (1.2-2.4), in terms of hemostatic effectiveness of the pack and of some patient parameters such as age and amount and type of volume infused. Results: the mean age of the patients was 57 years (51, 56 and 64). Only one had been previously irradiated. The bleeding was of venous origin, from the fossa of the obturator nerve, the iliac plexus and the presacral plexus. The volume expander most often used was 0.9% physiological saline solution, followed by blood derivatives and by Ringer lactate. Two patients were submitted to ligation of the hypogastric vein during surgery, with no improvement. The use of hemostatic synthetic material was inefficient in all three cases. In one of the patients, the use of nonabsorbable sutures to close the bleeding area led to a considerable reduction of bleeding, but did not eliminate it completely. One patient died before 24 h had elapsed, with signs and symptoms of heart failure. The other two patients developed acute renal failure and one of them developed aspirative pneumonia during surgical reexploration. Conclusion: massive bleeding is related to high morbidity and mortality. Among the emergency measures used for hemostasis, the pack seems to be the most adequate.
