In the baseline medical chart evaluation, data on epidemiology, pathological, treatment patterns, toxicities, and clinical outcomes will be collected. LACOG (Sponsor) will be responsible for managing data from this study, including quality verification. Manually entered data will be captured via EDC using eCRFs. The EDC system used in this study will be REDCap (Research Electronic Data Capture) - that meets the established standards approved for the safety of health information and is validated. REDCap is a secure, web-based software platform designed to support data capture for research studies, providing 1) an intuitive interface for validated data capture; 2) audit trails for tracking data manipulation and export procedures; 3) automated export procedures for continuous data downloads for common statistical packages; and 4) procedures for data integration and interoperability with external sources. The system also meets ICH guidelines on electronic handling of study data and will be available for audit upon request. Patient confidentiality will be strictly maintained.\n\nAn informed consent form will be offered to all living patients. The consent will be unnecessary in patients that could not be reached or that have passed away (died) as per regulation Res. CNS 466\u002F12 item IV.8.
