Factors Affecting Colorectal Cancer Screening in Primary Care Physician Practices in Ukraine.

Purpose: This study aims to identify the factors influencing colorectal cancer (CRC) screening practices, along with the barriers and facilitators from the perspective of primary care physicians (PCPs) in Ukraine. Considering health care system challenges, including those posed by the ongoing war, this research seeks to inform improvements in CRC screening and outcomes in Ukraine and other low- and middle-income countries (LMICs).

Methods: A survey was designed and distributed electronically to Ukrainian PCPs, focusing on CRC screening practices, beliefs, and barriers.

Colonoscopy Needs for Implementation of a Colorectal Cancer Screening Program in Ukraine.

Background: In Ukraine, there is no established colorectal cancer screening program. We aimed to project the number of screening colonoscopies needed for implementation of various CRC screening strategies in Ukraine.

Methods: We modified a previously developed Markov microsimulation model to reflect the natural history of adenoma and CRC progression among average-risk 50-74-year-olds.

Radiation-associated extraskeletal osteosarcoma of the chest wall.

Radiation-associated sarcoma is a rare but potential complication of radiation therapy. Most reported cases of osteosarcoma of the chest wall following radiation therapy for breast cancer arise from the chest wall skeletal structures. In contrast, few cases of extraskeletal osteosarcomas have been reported.
