PURPOSE: To determine the rate of underestimation of an image-guided core biopsy of nonpalpable breast lesions, with validation by histologic examination after surgical excision. METHODS: We retrospectively reviewed 352 biopsies from patients who were submitted to surgery from February 2000 to December 2005, and whose histopathologic findings were recorded in the database system. Results were compared to surgical findings and underestimation rate was determined by dividing the number of lesions that proved to be carcinomas at surgical excision by the total number of lesions evaluated with excisional biopsy. Clinical, imaging, core biopsy and pathologic features were analyzed to identify factors that affect the rate of underestimation. The degree of agreement between the results was obtained by the percentage of agreement and Cohen's kappa coefficient. The association of variables with the underestimation of the diagnosis was determined by the chi-square, Fisher exact, ANOVA and Mann-Whitney U tests. The risk of underestimation was measured by the relative risk (RR) together with the respective 95% confidence intervals (95%CI). RESULTS: Inconclusive core biopsy findings occurred in 15.6% of cases. The histopathological result was benign in 26.4%, a high-risk lesion in 12.8% and malignant in 45.2%. There was agreement between core biopsy and surgery in 82.1% of cases (kappa=0.75). The false-negative rate was 5.4% and the lesion was completely removed in 3.4% of cases. The underestimation rate was 9.1% and was associated with BI-RADS® category 5 (p=0,01), microcalcifications (p CONCLUSIONS: The core breast biopsy under image guidance is a reliable procedure but the recommendation of surgical excision of high-risk lesions detected in the core biopsy remains since it was not possible to assess clinical, imaging, core biopsy and pathologic features that could predict underestimation and avoid excision. Representative samples are much more important than number of fragments.

PURPOSE: to determine the accuracy of fine-needle aspiration biopsy (FNAB) and of core-needle biopsy (CNB) in diagnosing breast lumps and breast cancer. METHODS: this was a cross-sectional, retrospective and descriptive study based on the review of medical records. FNAB and CNB were carried out sequentially according to the routine of the Mastology Service. Both percutaneous procedures were applied to 233 patients during the period from March 2005 to February 2007. Women aged 18 years or more with changes in the clinical and/or image examination of the breast or a family history of breast and/or ovarian cancer were included. FNAB and CNB were carried out according to the technical recommendations of the National Institute of Cancer. The percentage of agreement, Cohen's Kappa coefficient, sensitivity, specificity, positive and negative predictive values and the accuracy of FNAB and CNB were calculated, considering the surgical biopsy as the gold standard. RESULTS: the average age of the patients was 49.0 years (±12.7) and the tumors measured 26.9 mm on average (±23.1), being larger than 20 mm in 47.2% of cases. Sensitivity, specificity, positive and negative predictive values and accuracy were higher for CNB than for FNAB, regardless of the size of the breast lesion. The diagnostic accuracy was 97.5% for CNB and 77.5% for FNAB. CONCLUSION: although the CNB showed higher rates of sensitivity, specificity, positive predictive value, negative predictive value and accuracy than FNAB for palpable and non-palpable breast lumps, the method remains useful for the minimally invasive diagnosis of mammary lesions, especially when its results are analyzed together with the clinical and imaging examination.

To compare the predictive capability of HPV and Pap smear tests for screening pre-cancerous lesions of the cervix over a three-year follow-up, in a population of users of the Brazilian National Health System (SUS).
This is a retrospective cohort study of 2,032 women with satisfactory results for Pap smear and HPV tests using second-generation hybrid capture,made in a previous study. We followed them for 36 months with data obtained from medical records, the Cervix Cancer Information System (SISCOLO), and the Mortality Information System (SIM). The outcome was a histological diagnosis of cervical intraepithelial neoplasia grade 2 or more advanced lesions (CIN2ş). We constructed progression curves of the baseline test results for the period, using the Kaplan-Meier method, and estimated sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ratios for each test.
A total of 1,440 women had at least one test during follow-up. Progression curves of the baseline test results indicated differences in capability to detect CIN2ş (p < 0.001) with significantly greater capability when both tests were abnormal, followed by only a positive HPV test. The HPV test was more sensitive than the Pap smear (88.7% and 73.6%, respectively; p < 0.05) and had a better negative likelihood ratio (0.13 and 0.30, respectively). Specificity and positive likelihood ratio of the tests were similar.
These findings corroborate the importance of HPV test as a primary cervical cancer screening.

To assess the adherence to a cervical cancer screening program and to identify reported reasons for inadequate screening in women receiving care as part of the Family Health Strategy.
A selective prevalence study on cervical cancer screening in women receiving care as part of the Family Health Strategy in the cities of Duque de Caxias and Nova Iguaçu in the state of Rio de Janeiro, southeastern Brazil, nine years after they participated in a previous study of the Brazilian National Cancer Institute. Only those women who were not diagnosed with CIN II or more severe lesions by histopathology, did not undergo hysterectomy during the study period and still resided in the communities were eligible to participate in the study. Information on exam sites, test results and schedules, sociodemographic characteristics and reported reasons of non-adherence was obtained. Data were collected through interviews and medical record review. The prevalence of adherence to screening was estimated, and the chi-square test was used to compare proportions between the variables studied and their relationship with the reported reasons of non-adherence to screening.
A total of 764 women were interviewed, 70.7% of whom received adequate cervical cancer screening. The reported reasons for inadequate screening included: no risk perception (44.6%), social barriers (26.3%), perceived barriers to action (22.3%) and institutional barriers (21.4%). These reasons were proportionately higher among residents of Nova Iguaçu than among residents of Duque de Caxias (p<0.01), except for institutional barriers (p=0.19).
Although difficulties and barriers were reported, there was good adherence to cervical cancer screening among the women studied. Health providers should receive proper training for complying with the Brazilian Ministry of Health guidelines of regular testing and to facilitate access to screening.

PURPOSE: to identify the pattern of myoelectrical activity of muscles from the scapular region, after axillary lymphadenectomy in breast cancer. METHODS: prospective cohort study including all the women submitted to axillary lymphadenectomy for surgical treatment of breast cancer, in a breast cancer reference center, from June to August 2006. The women were evaluated before, and after 3 and 12 months from the surgery, through physical and electromyographic examinations of the serratus anterior, upper trapezius and middle deltoid muscles. RESULTS: the patients' average age was 60.3 years old (DP±14.1), and the incidence of winged scapula at the physical examination was 64.9%. At the third-months evaluation, a reduction of 28.3 µV was observed in the myoelectrical activity of the serratus anterior muscle. At the twelveth-months evaluation and between the 3rd and the 12th month, there was an increment of 23.3 µV and 43.6 µV, respectively. For the upper trapezius, the increase was of 23.1 µV at the third-months evaluation, and 23.3 µV and 43.6 µV between the 3rd and the 12th months. As compared to before the surgery, the evaluation of the middle deltoid muscle did no present significant differences. CONCLUSIONS: considering muscle activity evaluated by surface electromyography, there was a decrease in the myoelectrical activity of the serratus anterior, due to lesion of the long thoracic nerve (neuropraxia), in the immediate postoperative evaluation. The increase of the mean square root of the electromyographic signal of the upper trapezius muscle, since the preoperative evaluation, suggests a muscular compensation related to the serratus anterior muscle's deficit.

To assess the determinants of late stage in women with cervical cancer in Brazil.
A cross-sectional study of secondary basis. Women with invasive cervical cancer enrolled in the Cancer Hospital Registry between January 2000 and December 2009 were included. Late clinical stage (≥IIB) was the outcome considered. The following variables were studied: age at diagnosis, race or ethnicity, years of education, marital status, alcohol consumption, smoking status, place of residence, year of diagnosis, initial treatment received, and status after the first treatment. Odds ratio (OR) with 95% confidence intervals (95%CI) and a logistic regression model were used. P values<0.05 were considered statistically significant.
37,638 cases were included, with a mean age of 52.4±14.1 years. Late clinical stages were observed in 70.6% of cases and were associated with the presence of squamous cell carcinoma (OR=1.8; 95%CI 1.7-2.0), age ≥50 years (OR=1.5; 95%CI 1.4-1.6), living with a partner (OR=1.3; 95%CI 1.2-1.4), black skin color (OR=1.2; 95%CI 1.1-1.4), and low educational level (OR=1.2; 95%CI 1.1-1.3).
In Brazil, the diagnosis of cervical cancer is a delayed event. Although the main factor associated with late stage of cervical cancer identified in this study is a biological factors (histological type) and, consequently, not eligible for intervention, it was confirmed that socioeconomic disparities in the country are associated with late stage disease.

, To analyze the factors associated with health-related quality of life (HRQoL) in women with cervical cancer (CC) in a single center in Rio de Janeiro, state of Rio de Janeiro, Brazil.
A cross-sectional study in women with a diagnosis of CC followed-up in the gynecology outpatient clinic of the Hospital do Câncer II (HCII, in the Portuguese acronym) of the Instituto Nacional de Câncer (INCA, in the Portuguese acronym). The data were collected from March to August 2015. Women with palliative care, communication/cognition difficulty, undergoing simultaneous treatment for other types of cancer, or undergoing chemotherapy and/or radiation therapy were excluded. For the evaluation of the HRQoL, a specific questionnaire for women with CC was used (Functional Assessment of Cancer Therapy - Cervix Cancer [FACT-Cx]). The total score of the questionnaire ranges from 0 to 168, with higher scores indicating a better HRQoL.
A total of 115 women were included in the present study, with a mean age of 52.64 years old (standard deviation [SD] = 12.13). The domains of emotional (16.61; SD = 4.55) and functional well-being (17.63; SD = 6.15) were those which presented the worst scores. The factors that had an association with better HRQoL in women with CC were having a current occupation, a longer time since the treatment and diagnosis, and women who had undergone hysterectomy.
Considering the domains of HRQoL of the women treated for cervical cancer, a better score was observed in the domains of physical and social/family wellbeing. For most domains, better scores were found between those with a current occupation, with a longer time after the diagnosis and treatment, and among those who had undergone a hysterectomy.
