Survival of patients with mucosal melanoma in Cali, Colombia: a retrospective cohort study.

Background: Mucosa melanoma is a rare condition with aggressive behavior and a less favorable prognosis compared to cutaneous melanoma. The objective of this study was to estimate the overall survival and clinical outcomes of patients diagnosed with mucosal melanoma in a Colombian hospital.

Methods: A retrospective cohort study was conducted at Fundación Valle del Lili, a single center located in Cali, Colombia.

Automated extraction of information from free text of Spanish oncology pathology reports.

Background: Pathology reports are stored as unstructured, ungrammatical, fragmented, and abbreviated free text with linguistic variability among pathologists. For this reason, tumor information extraction requires a significant human effort. Recording data in an efficient and high-quality format is essential in implementing and establishing a hospital-based-cancer registry.

Cost-Effectiveness of Pembrolizumab as an Adjuvant Treatment in Colombia for Melanoma Patients with Lymph Node Involvement After Complete Resection.

Introduction: The KEYNOTE-054 trial found that adjuvant treatment with pembrolizumab improved recurrence-free survival versus placebo in completely resected high-risk stage III melanoma patients. We assessed the cost-effectiveness of adjuvant pembrolizumab in Colombia compared with watchful waiting, a widely used strategy despite the high risk of recurrence with surgery alone.

Methods: A four-health state [recurrence-free (RF), locoregional recurrence (LR), distant metastases (DM), and death) Markov model was developed to assess the lifetime medical costs and outcomes (3% annual discount), along with cost-effectiveness ratios (ICERs).

Indigenous communities in Colombia: A cultural and holistic view of cancer management.

Cancer is one of the most burdening global health challenges. Indigenous communities are at high risk for worse healthcare outcomes because of inequalities in the incidence, prevalence, and mortality of oncological diseases, that arise from socioeconomic, racial, cultural, religious beliefs, and ethnic factors. Their perception about themselves is closely related to what affects their territory, making them possess a profound rooted feeling with their surroundings, and intense spiritual believes.
