- ItemDisección endoscópica submucosa para el tratamiento de neoplasias incipientes del tubo digestivo: experiencia en un centro universitario de alto volumen(2021) Mejía, Ricardo; Sáez, Josefina; Briones, Pamela; Norero, Enrique; Ceroni, Marco; Díaz, Alfonso; Sharp, AllanBackground: Endoscopic submucosal dissection (ESD) allows en-bloc resection of early gastro-intestinal neoplasms (EGIN) with healing potential. Aim: To describe the results of patients treated with ESD for EGIN by our team. Patients and Methods: Descriptive study of patients with EGIN who underwent ESD with curative intention between January 2008 and March 2020. Results: One hundred thirty-two ESD were performed in 127 patients. 77% were gastric lesions, 14% colorectal, 8% esophageal and 1% duodenal. En-bloc resection was achieved in 98.4% of ESDs. Eighty eight percent of patients met curative standards. Overall, cancer-specific, and recurrence-free survival were 95%, 100% and 98% respectively. Conclusions: ESD allows en-bloc resections with curative potential in selected patients, but with a significant reduction in morbidity and mortality and less impact on quality of life. Our results suggest the feasibility to perform ESD in our country with results comparable to those reported in the literature.
- ItemImpact of Adjuvant FOLFOX on Quality of Life and Peripheral Neuropathy Incidence in Patients With Gastric Cancer: A Prospective Cohort Study(Elsevier Inc., 2023) Mondaca Contreras, Sebastián Patricio; Pinto, Mauricio P.; Briones Carvajal, Juan Rodrigo; Caire, Nicole; Peña Prado, José Tomas; Koch Hein, Erica Cristina; Muñiz Muñoz, Maria Sabrina; Herrera, María Elisa; Sanchez Rojel, Cesar Giovanni; Galindo Aranibar, Héctor Gonzalo; Pizarro Brito, Gonzalo Ignacio; Acevedo Claros, Francisco Nicolas; Ibáñez Cáceres, Carolina; Balmaceda Araque, Carlos Felipe; Norero, Enrique; Duran, Doris; Garrido Salvo, Marcelo Adán; Nervi Nattero, BrunoObjectives: Perioperative and adjuvant chemotherapy have demonstrated clinical benefits in localized gastric cancer. Nevertheless, the reports on their effects on patient's health-related quality of life (HRQoL) are scarce. Here, we prospectively assessed quality of life and the incidence of chemotherapy-induced peripheral neuropathy (CIPN) in a cohort of patients treated with adjuvant FOLFOX. Methods: Localized stomach or gastroesophageal junction adenocarcinoma patients who underwent curative resection were recruited at a single center. All patients received adjuvant FOLFOX6, and HRQoL and CIPN were assessed using the European organization for research and treatment of cancer quality life (EORTC) C30 and the EORTC CIPN20 questionnaires, respectively. Clinically significant deterioration of HRQoL was also assessed as a coprimary outcome in a longitudinal analysis. Results: We recruited a total of 63 patients. Median age was 62.5 years, and 75% had stomach tumors. Twenty-four weeks after the start of treatment, the probability of being free from HRQoL deterioration and CIPN was 29% (95% confidence interval [CI] 18%-42%) and 6% (95% CI 2%-17%), respectively. Five-year disease-free survival was 45% (95% CI 24%-64%) and 5-year overall survival was 63% (95% CI 48%-76%). Conclusions: Adjuvant FOLFOX is associated with a high rate of long-term survival in localized gastric cancer; nevertheless, it has detrimental effects on patients’ quality of life.
- ItemLong-term Results of Endoscopic Submucosal Dissection (ESD) for the Treatment of Early Gastric Cancer (EGC) in a High-volume Latin American Center(2021) Mejía, Ricardo; Sáez, Josefina; Norero, Enrique; Briones, Pamela; Ceroni, Marco; Martínez, Cristian; Díaz, Alfonso; Calvo, Alfonso; Sharp, AllanBackground: Gastric cancer is the second leading cause of death by cancer worldwide. Endoscopic submucosal dissection (ESD) is a technique that allows en bloc resection of early lesions of the digestive tract. It has curative potential in selected patients and benefits over gastrectomy for the treatment of early gastric cancer (EGC). The aim of this study is to present the results of ESD for EGC in a high-volume center in Chile. Materials and Methods: Retrospective descriptive study of patients who underwent ESD for EGC at the Doctor Sótero del Río Hospital. Results: A total of 100 ESDs were performed in 96 patients between 2008 and 2020. Fifty-five percent were female patients, the average age was 68 years (range, 45 to 89 y). En bloc resection was achieved in 98% of cases and the rate of complications Clavien grade III or higher was 8.3%. There were no cases of perioperative mortality. Ninety-three percent of the dissections were classified as R0 and 83% met curative standards according to expanded criteria. The mean follow-up was 42 months (range, 1 to 144 mo). Overall survival was 97%. Cancer-specific survival was 100% and recurrence-free survival was 97%. Conclusions: The present study describes the largest series of ESD for the treatment of EGC reported in Latin America. Our results support the feasibility of implementing ESD in Chile and indicate good oncological outcomes comparable to those reported in the large Asian series published to date.
