RESUMEN
BACKGROUND: Colorectal cancer (CRC) is the second cause of cancer death in the world and is estimated to have been responsible for almost 935,000 deaths during 2020. OBJECTIVE: Describe clinicopathological features, overall survival (OS) and progression-free survival (PFS) in CRC patients under 30 years. METHOD: This is a retrospective cohort study in patients under 30 years diagnosed with CRC. RESULTS: From 2017 to 2021, 1823 patients were diagnosed with CRC, of which 54 (2.96%) were under 30 years. The OS, during 4 years, was 41.5%. The clinical stage found IV (hazard ratio [HR]: 6.212; 95% confidence interval [95% CI]: 2.504-15.414; p < 0.001), giving neoadjuvant therapy (HR: 0.705; 95% CI: 0.499-0.996; p = 0.047) and no medical history of Lynch syndrome (HR: 3.925; 95% CI: 1.355-11.364; p = 0.012) are independent predictors of mortality. The PFS, during 4 years, was 21.3%. Clinical stage IV (HR: 2.418; 95% CI: 1.000-5.850; p < 0.050), and no diagnosis of Lynch syndrome (HR: 3.800; 95% CI: 1.398-10.326; p = 0.009) are independent predictors. CONCLUSIONS: Younger patients are usually diagnosed with CRC in advanced stages. Early symptoms and evaluation, irrespective of age, are crucial.
ANTECEDENTES: El cáncer colorrectal (CCR) es la segunda causa de muerte por cáncer en el mundo y se estima que fue responsable de casi 935,000 muertes durante el año 2020. OBJETIVO: Describir las características clinicopatológicas, la supervivencia global (SG) y la supervivencia libre de progresión (SLP) en pacientes con CCR menores de 30 años. MÉTODO: Estudio de cohorte retrospectivo en pacientes con diagnóstico de CCR menores de 30 años. RESULTADOS: Entre 2017 y 2021 se diagnosticaron 1823 pacientes con CCR, de los cuales 54 (2.96%) eran menores de 30 años. La SG a 4 años fue del 41.5%. Se encontró que la etapa clínica IV (hazard ratio [HR]: 6.212; intervalo de confianza del 95% [IC95%]: 2.504-15.414; p < 0.001), recibir tratamiento neoadyuvante (HR: 0.705; IC95%: 0.499-0.996; p = 0.047) y no tener antecedente de síndrome de Lynch (HR:3.925; IC95%: 1.355-11.364; p = 0.012) son predictores de mortalidad independientes. La SLP a 4 años fue del 21.3%. La etapa clínica IV (HR: 2.418; IC95%: 1.000-5.850; p < 0.050) y el no contar con diagnóstico de síndrome de Lynch (HR: 3.800; IC95%: 1.398-10.326; p = 0.009) son predictores independientes. CONCLUSIONES: Los pacientes jóvenes son diagnosticados con CCR en etapas avanzadas. Los síntomas iniciales, junto con la evaluación, independientemente de la edad, son cruciales.

Background: Gallbladder epidermoid carcinoma is rare and more common in women over 55 years of age. Aim: To report the features of 15 patients with gallbladder epidermoid carcinoma. Material and Methods: Review of medical records of patients with gallbladder cancer in an oncology service. Results: Of 207 patients with gallbladder cancer, 15patients aged 53-72years, 93% women had an epidermoid component in their cancer. Forty percent were diabetic and 33% had cholelithiasis. All had locoregional extension of the tumor. A cholecystectomy was done in nine patients (using open surgery in six). In six patients, only a biopsy was done. Median survival was 4.2 months. Conclusions: Gallbladder epidermoid carcinoma is uncommon and has a bad prognosis.
