Methods and implementation of a Hospital-Based Cancer Registry in a major city in a low-to middle-income country: the case of Cali, Colombia.

PURPOSE: To describe our experience upon developing and implementing a hospital-based cancer registry (HBCR) in a quaternary-level of care private non-profit academic medical center in Cali, Colombia.
METHODS: HBCRs capture, in a given institution, every single patient with a confirmed malignancy. In this study, all cases evaluated between 2014 and 2018 were included in the HBCR. In compliance with the International Agency for Research on Cancer recommendations, cases were classified as analytic or non-analytic. Data derived from an exhaustive selection of patients was stored in a computing platform owned by the institution, meeting the 2016 Facility Oncology Registry Data Standards recommendations. Quality control was performed by evaluating comparability, timeliness, validity, and completeness.
RESULTS: A total of 24,405 new cases were registered between 2014 and 2018, from which 4253 (17.4%) died. Among all cases, based on the anatomic location, most common malignancies were breast (n = 1554), thyroid (n = 1346), hematolymphoid (n = 1251), prostatic (n = 805), and colorectal (n = 624). The behavior of the new cases was consistent with an incremental trend.
CONCLUSION: Upon implementing the HBCR, major challenges were identified (i.e., a precise definition of cases, the development of processes for capturing new cases, a standardized data collection strategy, and carrying-out an appropriate patient follow-up). Based on our experience, the success of an HBCR largely relies on the interest from the institution, the engagement of stakeholders and financial support, that is, it depends on the adequate access over time to funding, technological, and staffing resources.
