Indoleamine 2,3-dioxygenase and tryptophan 2,3-dioxygenase expression in HPV infection, SILs, and cervical cancer.

Background: Human papillomavirus (HPV) infection is the central factor for cervical cancer, whereas epithelial immune mechanisms contribute to the progression of HPV infection and its associated lesions. The authors evaluated the expression of indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) in cervicovaginal samples from women with normal cervical epithelium or with different degrees of squamous intraepithelial lesions (SILs) and cervical cancer.

Methods: IDO expression was analyzed by immunocytochemistry in liquid-based cytology samples from 165 women, of whom 42 had cervical changes subclassified as low-grade SIL (n = 6), high-grade SIL (n = 30), or squamous cell carcinoma (SCC) (n = 6), and 123 had negative Papanicolaou smears.

Clinical Features and Management of Women with Borderline Ovarian Tumors in a Single Center in Brazil.

Objective:  The aim of the present study was to describe and analyze data of 57 women with borderline ovarian tumors (BOTs) regarding histological characteristics, clinical features and treatment management at the Department of Obstetrics and Gynecology of the Universidade Estadual de Campinas (Unicamp, in the Portuguese acronym).

Methods:  The present retrospective study analyzed data obtained from clinical and histopathological reports of women with BOTs treated in a single cancer center between 2010 and 2018.

Results:  A total of 57 women were included, with a mean age of 48.

Exosomes-mediate microRNAs transfer in breast cancer chemoresistance regulation.

Breast cancer is the most common and fatal type of cancer in women worldwide due to the metastatic process and resistance to treatment. Despite advances in molecular knowledge, little is known regarding resistance to chemotherapy. One highlighted aspect is the DNA damage response (DDR) pathway that is activated upon genotoxic damage, controlling the cell cycle arrest or DNA repair activation.

Comparing the Copenhagen Index (CPH-I) and Risk of Ovarian Malignancy Algorithm (ROMA): Two equivalent ways to differentiate malignant from benign ovarian tumors before surgery?

Aim: To evaluate the prediction of malignancy in women with pelvic masses using the Copenhagen Index (CPH-I) and Risk of Ovarian Malignancy Algorithm (ROMA).

Patients And Methods: Three hundred eighty four women operated due to an ovarian mass were enrolled between January 2010 and June 2015. All patients had histopathological diagnosis, HE4 and CA125 measurement.

Up-regulation of DNAM-1 and NKp30, associated with improvement of NK cells activation after long-term culture of mononuclear cells from patients with ovarian neoplasia.

This study aimed at evaluating the functional activation and activating receptors expression on resting, short- and long-term NK and NK-like T cells from blood of ovarian neoplasia patients. Blood from patients with adnexal benign alterations (n = 10) and ovarian cancer (grade I-IV n = 14) were collected after signed consent. Effector cells activation was evaluated by the expression of the CD107a molecule.

Cytomorphological criteria, subclassifications of endocervical glandular cell abnormalities, and histopathological outcome: a frequency study.

The objective of this study was to evaluate the frequency and the significance of cytomorphological criteria defined in studies as being predictive of neoplasia in cervical smears of women with a cytological diagnosis of atypical glandular cells (AGC) or adenocarcinoma in situ (AIS). Women (n = 103) with cytological findings suggestive of AGC or AIS, whose diagnoses were later established by histopathology, were included in the study. The criteria analyzed and classified as present or absent in cervical smears previously classified as AGC-NOS (not otherwise specified), AGC-FN (favor neoplasia), or AIS were as follows: irregular nuclear membranes; scanty cytoplasm; dyskeratotic cells; increased nuclear/cytoplasmic ratio; nucleoli; overlapping; papillary clusters, feathering; loss of polarity; nuclear enlargement; coarsely granular chromatin; and pseudostratified strips.

Phylogenetic classification of human papillomavirus genotypes in high-grade cervical intraepithelial neoplasia in women from a densely populated Brazilian urban region.

Context And Objective: Differences in human papillomavirus (HPV) types may correlate with the biological potential and invasion risk of high-grade cervical intraepithelial neoplasia (CIN 2 and CIN 3). The objective of this study was to determine the relationship between different combinations of HPV types and CIN severity.

Design And Setting: Cross-sectional study, at Universidade Estadual de Campinas (Unicamp).

The impact of a community intervention to improve cervical cancer screening uptake in the Amazon region of Brazil.

Context And Objective: In the northern region of Brazil, cervical cancer is the most important cause of cancer-related deaths among women. There is considerable likelihood, however, that official incidence and mortality figures are greatly underestimated. The aim of this study was to estimate the repercussions from improvement in cervical cancer screening programs on the incidence of pre-invasive and invasive cervical lesions in a municipality in this region.

Variants of human papillomavirus types 16 and 18: histological findings in women referred for atypical glandular cells or adenocarcinoma in situ in cervical smear.

Human papillomavirus (HPV) genotypes cannot fully explain the histological diagnosis of women with glandular abnormalities detected by cervical smear. Thus, this study was designed to analyze the distribution of HPV-16 and HPV-18 variants in women referred because of atypical glandular cells and adenocarcinoma in situ in their cervical smears and its association with histological results. Twenty-four women with HPV-16 and 6 with HPV-18, selected from 160 women with cervical smears suggestive of glandular abnormalities, were included.

Cervical cancer in the developing world.

In developed countries, systematic screening programmes have reduced the morbidity and mortality resulting from cervical cancer. Cytological methods of screening have been the mainstay in these countries. Nevertheless, there is scant evidence that cytology-based screening has had any effect in reducing cervical cancer mortality in less-developed countries.
