Objectives: to evaluate the effectiveness of the neoadjuvant therapy in the irresecable or borderline resectable pancreatic adenocarcioma in terms of: 1) transformation into resecable; 2) survival; 3) toxicity. Patients and methods: the study consisted on an analysis of 375 patients diagnosed as having unresectable or borderline pancreatic adenocarcinoma, according to the NCCN criteria. Among them, 21 patients, 12 male and 9 female with an average age og 61.3 years (43-81) were treates with neoadjuvant therapy. Results: partial response was observed in 13 cases (61.9%), stable disease in 3 cases (14.3%) and progresión disease in 5 cases (23.8%). 5 of the partial response cases (23.8%) were considered resectable and duodenopancrectectomy was performed. 4 cases (80%) underwent a margin negative resection (R0) and one case (20%) underwent R1 resection. The median overall survival duration was 63.2 weeks (41.6-84.9; CI 95%). The median overall survival duration for the patients who underwent resection was greater than in those who didn´t: 121.6 weeks (52.6-190.6; IC 95%) vs. 47.7 (32.1-63.3; IC 95), respectively. Conclusions: neoadjuvant therapy in irresecable or bordeline resectable pancreatic adenocarnoma is associated to: 1) aceptable toxicity; 2) low rate of objective response; 3)low rate resecability; 4)poor survival.
Objetivos: evaluar la eficacia de la quimioterapia de conversión (QTC) en adenocarcinoma pancreático irresecable o de resecabilidad límite en términos de: 1) transformación en resecable; 2) supervivencia 3) toxicidad Material y Métodos: se analizaron 375 pacientes diagnosticados de adenocarcinoma pancreático. Entre ellos, se identificaron 21 pacientes, 12 hombres y 9 mujeres con una edad media de 61,3 años (43-81) y estadificados como localmente avanzados e irresecables o de resecabilidad límite de acuerdo con los criterios NCCN, que fueron tratados con quimioterapia neoadyuvante. Resultados: Se observó respuesta parcial en 13 casos (61,9%), enfermedad estable en 3 casos (14,3%) y progresión en 5 casos (23,8%). Se consideraron resecables 5 (23,8%) de los casos de respuesta parcial y se realizó duodeno-pancreatectomía. En 4 casos (80%) la resección fue R0 y en 1 (20%) fue R1. La estimación de supervivencia media de la serie fue de 63,2 semanas (41,6-84,9; IC 95%). Fue mayor en los pacientes intervenidos: 121,6 semanas (52,6-190,6; IC 95%) que en los no intervenidos: 47,7 (IC 32,1-63,3) (p=0,02). Conclusiones: La QTC en el adenocarcinoma pancreático irresecable o de resecabilidad límite se asocia a: 1) toxicidad aceptable; 2) tasa moderada de respuesta objetiva; 3) baja tasa de resecabilidad; 4) pobre supervivencia.
