- Surgical treatment of endometrial cancer in developing countries: reasons to consider systematic two-step surgical treatment(2015) ANTON, Cristina; FAVERO, Giovanni Mastrantonio di; KOEHLER, Christhardt; CARVALHO, Filomena Marino; BARACAT, Edmund Chada; CARVALHO, Jesus PaulaOBJECTIVE : The aim of this study was to determine the lymph node status in a large cohort of women with endometrial cancer from the public health system who were referred to an oncology reference center in Brazil to identify candidates for the omission of lymphadenectomy based on clinicopathological parameters. METHODS : We retrospectively analyzed a cohort of 310 women with endometrial cancer (255 endometrioid, 40 serous, and 15 clear cell tumors) treated between 2009 and 2014. We evaluated the histological type, grade (low vs. high), tumor size (cm), depth of myometrial invasion (<= 50%, > 50%) and lymphovascular space invasion to determine which factors were correlated with the presence of lymph node metastasis. RESULTS : The factors related to lymph node involvement were tumor size (p =0.03), myometrial invasion (p < 0.01), tumor grade (p < 0.01), and lymphovascular space invasion (p < 0.01). The histological type was not associated with the nodal status (p = 0.52). Only twelve of 176 patients (6.8%) had low-grade endometrioid carcinoma, tumor size <= 2 cm and < 50% myometrial infiltration. CONCLUSIONS : The omission of lymphadenectomy based on the histological type, grade, tumor size and depth of myometrial invasion is not likely to have a large impact on the surgical treatment of endometrial cancer in our population because most patients present with large and advanced tumors. New strategies are proposed that prioritize hysterectomy performed in a general hospital as soon as possible after diagnosis, followed by an evaluation of the need for lymph node dissection at a reference center.
- Breast cancer in very young women: Clinicopathological study of 149 patients <= 25 years old(2015) MOURA, Rafael de Deus; CARVALHO, Filomena M.; BACCHI, Carlos E.Background: Breast cancer in young women has different clinical and pathologic features and a more aggressive biological behavior when compared to breast cancers in older women. However, information is limited to the group of very young women (<25 years). Objectives: The aim of the present study was to investigate the pathological characteristics of breast cancer in 149 Brazilian women who were <= 25 years old at the time of breast cancer diagnosis. Materials and methods: Tumor samples diagnosed between 2003 and 2009 were analyzed from the archives of the Bacchi Laboratory. Results: In our series of 149 Brazilian women <= 25 years, 8.7% presented with in situ disease only. Of 136 invasive carcinomas, 91.9% were of the ductal type and 45.6% were of histological grade III. Overall, estrogen receptor (ER) was positive in 59.6% cases, and HER2 overexpression was detected in 32.8%. We also found a low prevalence of Luminal A cases and a high prevalence of Triple Negative cases. Statistical analysis showed that HER2 and basal-like groups had a lower overall survival expectation. Follow-up data showed high frequencies of regional lymph node metastasis, distant metastasis, and tumorrelated deaths. Conclusion: The present study represents the largest series of breast cancer arising in women <25 years and establishes the main clinical, pathological, immunohistochemical and follow-up features of this population.
