Despite its high incidence, there are currently no validated prevention and management recommendations specifically for the mexican population. Catechins, particularly epigallocatechin gallate and epicatechin, are emerging as a promising and readily accessible therapeutic option for radiation damage in skin and other organs, including conditions like esophagitis, intestinal injury, and mucositis.\n\nObjective This study aims to evaluate the utility of oral or topical catechins in preventing and managing acute and chronic radiation-induced dermatitis in cancer patients, comparing their effectiveness against standard treatment.\n\nMaterial and Methods\n\nThis will be a randomized, double-blind, phase III clinical trial with a longitudinal and comparative design. Patients will be allocated into two primary study groups: prevention (n=81) and treatment (n=81). Each group will be further divided into four treatment arms:\n\nEpigallocatechin gallate (experimental aerosol)\n\nEpicatechin (experimental capsule)\n\nSaline control arm (aerosol)\n\nMicrocrystalline cellulose excipient control arm (capsule)\n\nAll participants across all groups will receive standard care. Study endpoints will include the assessment of utility, toxicity, quality of life, and cosmesis, using various validated scales and scores.\n\nEthics This study adheres to the principles outlined in the Helsinki Declaration (2024), the Nuremberg Code, and Mexico's General Health Law on health research. Given the wide therapeutic margin of the interventions, the study is classified as minimal risk.\n\nStatistical Analysis To evaluate the efficacy of the intervention (specifically, the change in the risk of dermatitis and fibrosis), we will calculate the hazard ratio using Cox regression and compare it with the Log-Rank test. Additionally, both fixed and random effects models will be performed and compared using the likelihood ratio test."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Histopathologically confirmed diagnosis of cancer.\n* Complete blood count, blood chemistry, and liver function tests within normal ranges.\n* Availability of an anatomopathological report.\n* Aged between 18 and 75 years.\n* Karnofsky performance status (KPS) score \\> 60 or an Eastern Cooperative Oncology Group (ECOG) performance status score \\< 3.\n* Candidate for radiotherapy with a prescribed dose of ≥40 Gy or its biological equivalent (EQD2).\n* Must provide written informed consent to participate in the study.\n* Must be able to swallow capsules.\n* Must meet one of the following cohort-specific criteria:\n\n 1.
