RESUMO

PURPOSE: Assessing the role of breast MRI compared to galactography in patients with unilateral bloody or serous-bloody nipple discharge. MATERIALS AND METHODS: Retrospective study including 53 unilateral discharge patients who performed galactography and MRI. We evaluated the capability of both techniques in identifying pathology and distinguishing between nonmalignant and malignant lesions. Lesions BIRADS 1/2 underwent follow-up, while the histological examination after surgery has been the gold standard to assess pathology in lesions BIRADS 3/4/5. The ROC analysis was used to test diagnostic MRI and galactography ability. RESULTS: After surgery and follow-up, 8 patients had no disease (15%), 23 papilloma (43%), 11 papillomatosis (21%), 5 ductal cancer in situ (10%), and 6 papillary carcinoma (11%) diagnoses. Both techniques presented 100% specificity; MRI sensitivity was 98% versus 49% of galactography. Considering MRI, we found a statistical association between mass enhancement and papilloma (P < 0.001; AUC 0.957; CI 0.888-1.025), ductal enhancement and papillomatosis (P < 0.001; AUC 0.790; CI 0.623-0.958), segmental enhancement and ductal cancer in situ (P = 0.007; AUC 0.750; CI 0.429-1.071), and linear enhancement and papillary cancer (P = 0.011). CONCLUSIONS: MRI is a valid tool to detect ductal pathologies in patients with suspicious bloody or serous-bloody discharge showing higher sensitivity and specificity compared to galactography.

RESUMO

BACKGROUND: More information is needed on the anatomopathological outcome variables indicating the appropriate surgical strategy for the colorectal resections often needed during cytoreduction for ovarian cancer. METHODS: From a phase-II study cohort including 70 patients with primary advanced or recurrent ovarian cancer with diffuse peritoneal metastases treated from November 2000 to April 2009, we selected for this study the 52 consecutive patients who needed colorectal resection. Data collected included type of colorectal resection, peritoneal cancer index (PCI), histopathology (depth of bowel-wall invasion and lymph-node spread), cytoreduction rate and outcome. Correlations were tested between possible prognostic factors and Kaplan-Meier five-year overall and disease-free survival. A Cox multivariate regression model was used to identify independent variables associated with outcome. RESULTS: In the 52 patients, the optimal cytoreduction rate was 86.5% (CC0/1). In all patients, implants infiltrated deeply into the bowel wall, in 75% of the cases up to the muscular and mucosal layer. Lymph-node metastases were detected in 50% of the cases; mesenteric nodes were involved in 42.3%. Most patients (52%) had an uneventful postoperative course. Operative mortality was 3.8%. The five-year survival rate was 49.9% and five-year disease-free survival was 36.7%. Cox regression analysis identified as the main prognostic factors completeness of cytoreduction and depth of bowel wall invasion. CONCLUSIONS: Our findings suggest that the major independent prognostic factors in patients with advanced ovarian cancer needing colorectal resections are completeness of cytoreduction and depth of bowel wall invasion. Surgical management and pathological assessment should be aware of and deal with dual locoregional and mesenteric lymphatic spread.

RESUMO

AIMS: This study monitored blood glucose profiles in normotolerant breastfeeding women, with and without previous gestational diabetes, in real life in order to identify normal blood glucose fluctuations during breastfeeding. SUBJECTS AND METHODS: Two groups were studied: (1) 18 women with recent gestational diabetes mellitus but normotolerant postpartum (pGDM-N group) and (2) 15 women normotolerant both during pregnancy and postpartum (pN-N group). All participants underwent continuous glucose monitoring during which they recorded their main daily activities and three standardized events: "suckling," "meal," and "meal and suckling." Other than these three events, these women were essentially on an "ad lib" diet. Data were expressed as median and SD values. Student's t test and Fisher's test were used to compare mean, variances, and percentages. Differences were significant with P<0.05. Clustering analysis was used to determine the normal range of glucose values. RESULTS: The two groups were matched for age, follow-up duration, and monitoring measurements but not for body mass index. Blood glucose levels and variances were higher in the pGDM-N group, particularly during daytime and the three standardized events, and were not related to body mass index. Suckling had no direct effect on glucose profile during both the non-fed and the fed state. Blood glucose levels that best represent the normal breastfeeding population were between 50 and 126 mg/dL (from 2.8 to 7.0 mmol/L). CONCLUSIONS: Three months after delivery, normotolerant women with recent gestational diabetes had higher daily blood glucose levels than women who were always normotolerant, with no direct effect of suckling. The blood glucose profiles of healthy subjects could be representative of the normal range of the population during breastfeeding.
