The Quality of Pap Smears from the Brazilian Cervical Cancer Screening Program According to the Human Development Index

Brazil is a country with strong socioeconomic disparities, which may explain the different rates of cervical cancer incidence and mortality and influence the quality of cervical cancer screening tests. The aim of this study was to perform a trend analysis of some quality indicators of Pap smears according to the Municipal Human Development Index (MHDI). Information about cytopathological exams (approximately 65,000,000) performed from 2006 to 2014 in women ages 25 to 64 years was obtained from the Cervical Cancer Information...

The Brazilian TP53 mutation (R337H) and sarcomas

Sarcomas represent less than 1% of all solid neoplasms in adults and over 20% in children. Their etiology is unclear, but genetic susceptibility plays an important role in this scenario. Sarcoma is central in Li-Fraumeni Syndrome (LFS), a familial predisposition cancer syndrome. In Brazil, the high prevalence of p.Arg337His mutations in the TP53 gene brings about a unique condition: a cluster of LFS. In the present work, we studied 502 sarcoma patients not selected by age or family history in...

TERT Promoter Mutation C228T Increases Risk for Tumor Recurrence and Death in Head and Neck Cancer Patients

Background: Head and neck squamous cell carcinoma (HNSCC) is usually associated to tobacco and alcohol consumption. Increased telomerase activity has been consistently detected in 80–90% of malignant tumors, including HNSCC. Mutations within the promoter region of telomerase reverse transcriptase (TERT) that confer enhanced TERT promoter activity have been reported in two major hotspots, designated C228T and C250T. Objectives: To evaluate TERT promoter mutations C228T and C250T in HNSCC patients from Brazil and correlate with patients’ outcome. Materials and Methods: Formalin-fixed...

Surgical versus clinical staging prior to primary chemoradiation in patients with cervical cancer FIGO stages IIB–IVA: oncologic results of a prospective randomized international multicenter (Uterus-11) intergroup study

Objective: Revised staging of patients with locally advanced cervical cancer is based on clinical examination, imaging, and potential surgical findings. A known limitation of imaging techniques is an appreciable rate of understaging. In contrast, surgical staging may provide more accurate information on lymph node involvement. The aim of this prospective study was to evaluate the impact of pre-treatment surgical staging, including removal of bulky lymph nodes, on disease-free survival in patients with locally advanced cervical cancer. Methods: Uterus-11 was a...

Superiority of the triple combination of bortezomib, cyclophosphamide and dexamethasone versus cyclophosphamide, thalidomide and dexamethasone in patients with newly diagnosed multiple myeloma, eligible for transplantation

Background: The treatment of multiple myeloma (MM) has evolved significantly in the past decade, and new drug combinations have improved the response rates and prolonged survival. Studies comparing different induction chemotherapy regimens have shown that triple combinations have better results than double combinations. However, comparisons among different triple combinations are rare in the literature. Methods: We retrospectively compared two triple combinations comprising bortezomib, cyclophosphamide and dexamethasone (VCD) versus thalidomide, cyclophosphamide and dexamethasone (CTD), and aimed at identifying which of the...
