- Abstract : Background: Initial recurrence mapping of resected pancreatic ductal adenocarcinoma (PDAC) could help in stratifying patient subpopulations for optimal postoperative follow‐up. The aim of this systematic review and meta‐analysis was to investigate the initial recurrence patterns of PDAC and to correlate them with clinicopathological factors. Methods: MEDLINE and Web of Science databases were searched systematically for studies reporting first recurrence patterns after PDAC resection. Data were extracted from the studies selected for inclusion. Pooled odds ratios (ORs) and 95 per cent confidence intervals were calculated to determine the clinicopathological factors related to the recurrence sites. The weighted average of median overall survival was calculated. Results: Eighty‐nine studies with 17 313 patients undergoing PDAC resection were included. The weighted median rates of initial recurrence were 20·8 per cent for locoregional sites, 26·5 per cent for liver, 11·4 per cent for lung and 13·5 per cent for peritoneal dissemination. The weighted median overall survival times were 19·8 months for locoregional recurrence, 15·0 months for liver recurrence, 30·4 months for lung recurrence and 14·1 months for peritoneal dissemination. Meta‐analysis revealed that R1 (direct) resection (OR 2·21, 95 per cent c.i. 1·12 to 4·35), perineural invasion (OR 5·19, 2·79 to 9·64) and positive peritoneal lavage cytology (OR 5·29, 3·03 to 9·25) were significantly associated withAbstract : Background: Initial recurrence mapping of resected pancreatic ductal adenocarcinoma (PDAC) could help in stratifying patient subpopulations for optimal postoperative follow‐up.

Meta‐analysis revealed that R1 (direct) resection (OR 2·21, 95 per cent c.i. 1·12 to 4·35), perineural invasion (OR 5·19, 2·79 to 9·64) and positive peritoneal lavage cytology (OR 5·29, 3·03 to 9·25) were significantly associated with peritoneal dissemination as initial recurrence site. Low grade of tumour differentiation was significantly associated with liver recurrence (OR 4·15, 1·71 to 10·07). Conclusion: Risk factors for recurrence patterns after surgery could be considered for specific surveillance and treatments for patients with pancreatic cancer. Abstract : In this study, initial recurrence patterns and their prognosis after resection of pancreatic cancer were reviewed systematically, and a meta‐analysis undertaken of clinicopathological features of the primary tumour associated with each initial recurrence site. Based on the results, correctly predicting the site and prognosis of each recurrence could guide structured follow‐up after surgery and optimal treatment specific to recurrence site.

Pattern related to survival Abstract : Antecedentes: El mapeo del patrón de recidiva inicial tras la resección de un adenocarcinoma ductal pancreático ( pancreatic ductal adenocarcinoma, PDAC) podría ayudar a estratificar subpoblaciones de pacientes para un seguimiento postoperatorio óptimo. El objetivo de esta revisión sistemática con metaanálisis fue investigar los patrones de recidiva inicial de PDAC y correlacionarlos con factores clínico‐patológicos. Métodos: Se realizaron búsquedas sistemáticas en las bases de datos MEDLINE y Web of Science para seleccionar estudios que presentaran información sobre los patrones de recidiva inicial después de la resección del PDAC. Se extrajeron los datos de los estudios seleccionados para su inclusión en el metaanálisis. Se calcularon las razones de oportunidades agrupadas ( pooled odds rati o, OR) y los i.c. del 95% para definir los factores clínico‐patológicos relacionados con las localizaciones de la recidiva. Se estimó el promedio ponderado de la mediana de la supervivencia global. Resultados: Se incluyeron 89 estudios con 17.313 pacientes a los que se realizó una resección por PDAC. Las tasas medias ponderadas de las localizaciones de la recidiva inicial fueron del 20, 8% para la locorregional, 26, 5% para las hepáticas, 11, 4% para el pulmón y 13, 5% para la diseminación peritoneal. La mediana ponderada de supervivencia global fue de 19, 8 meses (locorregional), 15, 0 meses (hígado), 30, 4 meses (pulmón) y 14, 1 meses (diseminación peritoneal). El metaanálisis demostró que la resección R1 (inicial) (OR 2, 21, i.c. del 95% 1, 12–4, 35), la invasión perineural (OR 5, 19; i.c. del 95% 2, 79–9, 64) y la positividad de la citología del lavado peritoneal (OR 5, 29; i.c. del 95% 3, 03–9, 25) se asociaron significativamente con la diseminación peritoneal como localización de recidiva inicial. El bajo grado de diferenciación tumoral se asoció significativamente con la recidiva hepática (OR 4, 15; i.c. del 95%: 1, 71‐10, 07). Conclusión: Se podrían tener en cuenta estos factores de riesgo de los patrones de recidiva tras la cirugía para realizar un seguimiento y tratamiento específicos en pacientes con cáncer de páncreas. … (more)
