Subtipos Moleculares De Câncer De Mama Não Estão Associados Ao Subestadiamento Ou Ao Superestadiamento Do Câncer De Mama

Purpose to evaluate the agreement between the clinical and pathological stagings of breast cancer based on clinical and molecular features. Methods this was a cross-sectional study, in which clinical, epidemiological and pathological data were collected from 226 patients who underwent surgery at the Prof. Dr. José Aristodemo Pinotti Women’s Hospital (CAISM/Unicamp) from January 2008 to September 2010. Patients were staged clinically and pathologically, and were classified as: understaged, when the clinical staging was lower than the pathological staging; correctly staged, when the clinical staging was the same as the pathological one; and overstaged, when the clinical staging was greater than the pathological staging. Results understaged patients were younger (52.2 years; p < 0.01) and more symptomatic at diagnosis (p = 0.04) when compared with correctly or overstaged patients. Clinicopathological surrogate subtype, menopausal status, parity, hormone replace therapy and histology were not associated with differences in staging. Women under 57 years of age were clinically understaged mainly due to underestimation of T (tumor staging) (p < 0.001), as were the premenopausal women (p < 0.01). Patients whose diagnosis was made due to clinical complaints, and not by screening, were clinically understaged due to underestimation of N (lymph nodes staging) (p < 0.001). Conclusion the study shows that the clinicopathological surrogate subtype is not associated with differences in staging, while younger women diagnosed because of clinical complaints tend to have their breast tumors understaged during clinical evaluation. © 2016 by Thieme Publicações Ltda, Rio de Janeiro, Brazil.38523924

Infection By The Human Papillomavirus In Teenagers Sexually Active: Clinic And Subclinic Manifestations.

This research studies the association of the cervical condyloma with the intraepithelial neoplasia, during sex activity, pregnancy, diagnose methods, cytology and colposcopy in teenagers. The objective of this research is to study the propaedeutics for the uterine coli condyloma diagnose in a group of teenagers. For this purpose, we have studied 131 teenagers sexually active with ages between 14 and 19 years and presenting histologically confirmed uterine coli condyloma. Association with intraepithelial neoplasia, sexual activity duration, method of diagnose, pregnancy analysis, cytology and colposcopy results and association with vulva and vagina injuries were evaluated. The high association rate with condyloma and intraepithelial neoplasia after a short time of sexual activity and the none presence of macroscopic warts in the genital organs in 80% of cases presenting cervical condyloma, demonstrate that: a more careful investigation with colposcopy and biopsy of the inferior genitals of the women-teenagers sexually active is needed, when presenting modified cervical cytology.113494895

Complications and relapse rate in patients with vulvar squamous cell carcinoma undergoing radical vulvectomy with one or three incisions: study of 132 cases

The purpose of the present study was to compare postoperative complications and recurrence rates in 132 women with invasive vulvar carcinoma treated by radical vulvectomy and bilateral groin lymphadenectomy performed with one or three incisions. It was a nonrandomized retrospective clinical study, including 65 women operated using a single incision and 67 with three incisions, between 1986 and 1996. Fischer's, chi-square, Student's t tests followed by logistic regression were used for statistical analysis as well as survival curves by the Kaplan-Meyer method, compared using Wilcoxon test, followed by Cox regression, with the statistical significance limit of 5%. The groups were similar regarding age, smoking, presence of other diseases, histologic type and grade. Pathologic stage III was significantly more frequent in the single incision group, while free lymph nodes were more frequent in the three-incision group. The patients treated with triple incision showed statistically less frequent immediate complications (76% vs 92%, p<0.05), less dehiscence (72% vs 92%, p<0.01), and shorter mean hospital stay (19.4 days vs 38.7 days, p<0.001) and secondary procedures were less necessary (76% vs 94%, p<0.01). Seven postoperative deaths were observed: five with single incision and two with triple incision. Recurrence rate was statistically lower in patients treated with triple incision (19% vs 35%, p<0.01) and with negative lymph nodes (6% vs 15%, p<0.01). After Cox regression, only positive lymph nodes had negative influence on disease-free survival. We concluded that vulvectomy using three incisions shows less complications than single incision, without compromising therapeutic efficacy, independently of the stage of the disease.O objetivo deste estudo foi comparar as taxas de complicações pós-operatórias e a taxa de recidiva em 132 mulheres com carcinoma da vulva tratadas com vulvectomia radical e linfadenectomia inguinal bilateral com uma ou três incisões. Foi um ensaio clínico retrospectivo não randomizado, incluindo 65 mulheres operadas por incisão única e 67 por três incisões, entre 1986 e 1996. Para análise estatística foram realizados os testes Exato de Fischer, Qui-Quadrado, t de Student e regressão logística e curvas de sobrevida pelo método de Kaplan-Meyer, comparadas pelo teste de Wilcoxon, seguidas de regressão de Cox, com limite de 5% de significância estatística. Os grupos foram semelhantes com relação à idade, tabagismo, presença de síndromes clínicas, tipo e grau histológico. Pacientes com neoplasia no estadio III foram mais freqüentes no grupo de incisão única e mais linfonodos livres no grupo de três incisões. As pacientes tratadas com três incisões apresentaram significativamente menos complicações pós-operatórias imediatas (76% vs 92%, p<0,05), menos deiscências (72% vs 92%, p<0,01), menor necessidade de procedimentos secundários (76% vs 94%, p<0,01) e menor tempo de internação (média de 19,4 dias vs 38,7 dias, p<0,001). Ocorreram sete óbitos pós-operatórios: cinco no grupo tratado com incisão única e dois com três incisões. A taxa de recidiva foi significativamente menor nas operadas com três incisões (19% vs 35%, p<0,01) e com linfonodos livres de doença (6% vs 15%, p<0,01). Após a regressão de Cox, apenas os linfonodos comprometidos influenciaram negativamente o tempo livre de doença. Concluímos que a vulvectomia por três incisões apresenta menos complicações que a incisão única, sem comprometer a eficácia terapêutica, independente do estádio da neoplasia.9710

Cistos No Interior De Nódulo Mamários Benignos: Risco De Malignidade

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)The objective of this study is to assess whether the largest cyst diameter is useful for BI-RADS ultrasonography classification of predominantly solid breast masses with an oval shape, circumscribed margins, and largest axis parallel to the skin, which, except for the cystic component, would be likely classified as benign. Methods This study received approval fromthe local institutional review board. From March 2009 to August 2014, we prospectively biopsied 170 breast masses from 164 women. We grouped the largest cyst and mass diameters according to histopathological diagnoses. We used Student’s t-test, linear regression, and the area under the receiver operating characteristic curve (AUC) for statistical assessment. Results Histopathological examination revealed 143 (84%) benign and 27 (16%)malignant masses. The mean largest mass diameter was larger among malignant (mean ± standard deviation, 34.1 ± 16.6 mm) than benign masses (24.7 ± 16.7 mm) (P &lt; 0.008). The mean largest cyst diameter was also larger among malignant (9.9 ± 7.1 mm) than benign masses (4.6 ± 3.6 mm) (P &lt; 0.001). Agreement between measurements of the largest mass and cyst diameters was low (R2 = 0.26). AUC for the largest cyst diameter (0.78) was similar to the AUC for the largest mass diameter (0.69) (p = 0.2). A largest cyst diameter &lt; 3, ≥ 3 to &lt; 11, and ≥ 11 mm had a positive predictive value of 0, 15, and 52%, respectively. Conclusion A largest cystic component &lt; 3 mm identified within breast masses that show favorable characteristics may be considered clinically inconsequential in ultrasonography characterization. Conversely, masses with a largest cystic component ≥ 3 mm should be classified as BI-RADS-US category 4. © 2016 by Thieme Publicações Ltda, Rio de Janeiro, Brazil.3841701762012/15059-8, FAPESP, Fundação de Amparo à Pesquisa do Estado de São PauloFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Comparação entre a colpocitologia oncológica de encaminhamento e a da gravidade das lesões cervicais intra-epiteliais

OBJECTIVE: The study was designed to compare the Pap smear results, performed on the public health service, with: the results of Pap smear collected on the reference service; the colposcopy and punch biopsy results. METHODS: The total of 213 women assisted at the women's hospital ¾ from January 1989 to April 1991, and followed until July 1998 were selected. Ninety were referred because a Pap smears suggestive of Human Papillomavirus (HPV) induced lesion or cervical intraepithelial neoplasia (CIN) grade 1, and 123, CIN 2 or 3. RESULTS: Among the 90 women referred because of HPV/CIN 1.49% presented CIN 2 or 3 in the Pap smears performed at this service. At the colposcopy, 16/90 women did not present suspicious lesions, and in 10 women, the scamous colunar junction was not observed. At biopsy, 42 (46%) presented CIN 2 or 3. Out of the 123 women referred with Pap smear of CIN 2 or 3.54% presented CIN 2 or 3 at this service. At the colposcopy, 24 women did not present suspicious lesions and the scamous colunar junction was not observed in 12. About biopsy, 61 (49%) presented CIN 2 or 3. CONCLUSIONS: The expectant conduct in cases of Pap smear with HPV/CIN 1, should follow a criterion, involving qualified professionals to collect the Pap smear, and should provide people awareness as to control follow-up.OBJETIVO: Comparar o resultado da colpocitologia oncológica (CO) de encaminhamento com o resultado da CO coletada no serviço de referência, e avaliar as alterações da colposcopia e o resultado da biópsia. MÉTODOS: Foram selecionadas 213 mulheres atendidas de janeiro de 1989 a abril de 1991 de um centro especializado de atenção à saúde da mulher, com seguimento até julho de 1998. Noventa foram encaminhadas por CO sugestiva de lesão induzida pelo vírus do papiloma humano (HPV) ou neoplasia intra-epitelial cervical (NIC) grau 1 e 123 por CO sugestiva de NIC 2 ou 3. RESULTADOS: Das mulheres encaminhadas por CO HPV/NIC 1, 49% apresentavam NIC 2 ou 3 na CO do serviço. Na colposcopia, 16 não apresentavam lesões suspeitas e em 10 não se via a junção escamo-colunar. Ao diagnóstico histológico, 42 (46%) apresentavam NIC 2 ou 3. Das 123 mulheres encaminhadas com CO NIC 2 ou 3, 54% apresentaram NIC 2 ou 3 na CO do serviço. Na colposcopia, 24 mulheres não apresentavam lesões suspeitas e em 12 não se via a junção escamo-colunar. Na histologia, 61 (49%) apresentavam NIC 2 ou 3. CONCLUSÕES: A conduta expectante nos casos de CO HPV/NIC 1 deve ser criteriosa, envolvendo profissionais capacitados na coleta do exame, e conscientizar a população para retornos periódicos de controle

Associação de status menopausal, expressão de receptor de progesterona e de Ki67 à resposta clínica à quimioterapia neoadjuvante no câncer luminal de mama

To identify the biomarkers of response to neoadjuvant chemotherapy in early luminal breast cancer. Methods A cross-sectional study that included all patients with early or locally-advanced luminal breast cancer submitted to neoadjuvant chemotherapy between 2013 and 2014. Demographic, clinic and pathologic data were retrieved from patient records. The expressions of the estrogen receptor (ER), the progesterone receptor (PR), and Ki67 were analyzed by immunohistochemistry (IHC). The status of the human epidermal growth factor receptor 2 (HER2) was evaluated by IHC and fluorescent in situ hybridization (FISH). Independent predictors of clinic and pathologic response were evaluated by stepwise logistic regression models and receiver operating characteristic (ROC) curve analysis. Results Out of 298 patients identified, 115 were included in the analysis. Clinical complete response (cCR) was observed in 43.4% of the patients (49/113), and pathologic complete response (pCR) was observed in 7.1% (8/115) of the patients. The independent predictors of cCR were premenopausal status (p 50%; p = 0.048), and Ki67 expression >= 14% (versus 50%; p ¼ 0.048), e expressão de Ki67 14% (versus < 14%; p ¼ 0.01). Pacientes com RCc apresentaram maior probabilidade de serem submetidas a cirurgia conservadora da mama (34.7% versus 7.8%; p < 0.001). Aumento no ponto de corte para expressão de Ki67 foi associado a aumento da especificidade e redução da sensibilidade na identificação de pacientes com RCc. Conclusão Status premenopausal, baixa expressão de RP e maior expressão de Ki67 estiveram associados a maior taxa de RCc à quimioterapia neoadjuvante no câncer luminal de mam
