The asymptomatic progression of chemotherapy-induced cardiotoxicity poses a significant risk to breast cancer patients. In the present single-center cohort study, a predictive model for evaluating the risk of cardiotoxicity during or by the end of chemotherapy was designed. The risk-prediction nomogram was delineated and assessed.

This research aims to create a feasible algorithm for the early diagnosis of antitumor therapy cardiotoxicity in breast cancer patients. The paper represents a protocol for a prospective cohort study with N 120 eligible participants admitted for treatment with anthracyclines and/or trastuzumab.

Colposcopy performance was assessed using the modified Reid index in women aged 18-63 years. In total, 1,129 colposcopic-HPV-cytology triple samples and 94 histology findings were collected.

Methods: Rough incidence rates (per 100,000) and average annual percent changes (aAPCs) were estimated for each age group at diagnosis with respect to gender, ethnicity, residence, the disease stages, tumor subsite, and histology type using linear regression analysis, including the prognostic index for 2019-2020. Overall five-year survival rates were estimated by the Kaplan-Meier method.
High-risk human papillomavirus strains are widely known to be the causative agents responsible for cervical cancer development. Aggregated damage caused by papillomaviruses solely is estimated in at least 5% of all malignancies of the human body and 16% in cancers that affect the female genital area. Enhanced understanding of the complex issue on how the high extent of carcinogenicity is eventually formed due to the infection by the Papoviridae family would contribute to enhancing current prevention strategies not only towards cervical cancer, but also other HPV associated cancers.

Methods: Smears taken through (i) conventional cytology using azur-eosin staining and (ii) liquid-based cytology (LBC) 'Cell Scan' in the general female population and in women first diagnosed with cervical cancer were collected throughout the region. ROC-analysis with curve construction and weighted Cohen's κ calculation were applied.
Objective: to detect the HPV types distribution both in general female population and in women with first diagnosed cervical cancer, including viral load in both groups. Methods: Qualitative detection and quantification of HPV was performed by PCR-Real time method based on the Russian equipment and test systems (“DNA-Technology” LLC, Russia). The DNA of low-risk (HPV 6, 11, 44) and possibly / potentially / high carcinogenic risk (HPV 16, 18, 26, 31, 33 , 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82), a total of 21 types, were detected.
