Benign neoplasms of the colon, rectum, anus and anal canal are true neoplasia colon mucosa associated with a high risk colorectal cancer (CC). The literature review analyzes epidemiology, factors, modern methods diagnosis treatment, describes priority minimally invasive interventions for benign tumors.

More and more evidences suggest that primary colon and rectum tumors should not be considered as a single disease entity. In this manuscript, we evaluate the metastatic patterns of colon and rectum cancers and analyze the potential distribution of metastatic disease in these two malignancies. Data queried for this analysis include colorectal adenocarcinoma (2010-2011) from the Surveillance, Epi...

Background . During the COVID-19 pandemic, annual adult check-ups have been postponed, resulting in cancer screening disruption. The aim of study was to evaluate changes incidence and stage distribution malignancies included program during pandemic using Arkhangelsk Regional Cancer Registry (ARRC). Material Methods We assessed rates for colon, rectum, lung, breast, cervix, uterine body, ovary, ...

this article was aimed to provide an overview and a perspective on the changing impact of cancers with increasing age on three age groups. a population based cancer registry was undertaken to register all new cancers cases from march 2006 to march 2007. during one year, 2023 (41.1%) of 4922 patients with cancer were ≥65 years. the five most common cancers (excluding skin cancer) were stomach, b...

BACKGROUND Our aim is to explore the trend of association between the survival rates of colorectal cancer (CRC) and the different clinical characteristics in patients registered from 1960s to 2000s. We hypothesized that the survival rate of CRC increases over time and varies according to anatomic subsites. METHODS Information from a total of 4558 stage T(1-4)N(1-2)M0 CRC patients registered f...

The purpose of the study was to analyze rectal resection outcomes in patients with cancer. Material and Methods. A retrospective analysis treatment 251 stage cT3–4aN0–2M0 cancer, who underwent transperitoneal resections rectum mesorectumectomy from 2015 2020, carried out. age ranged 27 90 years. Considering extent tumor spread, 143 (56.9 %) neoadjuvant prolonged conformal radiation therapy or c...

BACKGROUND We aimed to explore the efficacy and safety profile of preoperative neoadjuvant chemoradiation (NACRT) in locally advanced rectal cancer (LARC) in upper rectum versus middle/lower rectum. METHODS The study included 173 patients with stage II or III (T2-4b, N0-2b) LARC who underwent NACRT followed by total mesorectal excision (TME) between January 2011 and October 2016. Cox regressi...

Cobalt-60 (Co-60) is a relatively new source for the application of high-dose rate (HDR) brachytherapy. Radiation dose to the rectum is often a limiting factor in achieving the full prescribed dose to the target during brachytherapy of cervical cancer. The aim of this study was to measure radiation doses to the rectum in-vivo during HDR Co-60 brachytherapy. A total of eleven HDR brachytherapy t...
