[Prognostic significance of the ratio of lymph node metastatic in 5-year survival after curative gastrectomy for advanced gastric carcinoma]. / Significancia pronóstica de la razón ganglionar metastásica en la sobrevida a cinco años luego de gastrectomía curativa por carcinoma gástrico avanzado.

OBJECTIVE: Determine the prognostic significance of metastatic lymph node ratio in 5-year survival of patients after curative distal gastrectomy for advanced gastric carcinoma. MATERIALS AND METHODS: This study survival analysis, prospective, observational, longitudinal, analyzed data from 68 patients with resectable advanced gastric adenocarcinoma treated at the Regional Institute of Neoplastic Disease Luis Pinillos Ganoza during the period 2008-2013. RESULTS: The number of metastatic lymph nodes ranged from 0-29 (mean, 3.9±5.8) and the number of resected lymph nodes understood ranges from 13 to 66 (mean 35.34±12.60). There was no significant correlation between the number of metastatic lymph nodes and number of resected lymph nodes (r=0.208, p=0.089). Survival of the total number at 5 years was 55.9%, with a median survival of 44.11±3.38 months According to regional nodal status (N) of the 7th edition of the UICC, patients with N0 (n=27), pN1 (n=12), pN2 (n=17) and pN3 (n=12) showed survival rates at 5 years of 77.2%, 27.2%, 46.3% and 40% respectively (p=0.005). Patients were stratified into NR0 (reason 0%), NR1 (ratio 1-59%) and NR2 (ratio >60%). Their survival rates at 5 years were 77.2%, 40.9% and 33.3% respectively (p=0.013). CONCLUSIONS: The metastatic lymph node ratio is a predictor system actuarial survival at 5 years compared consistent with regional nodal status (N) classification system of the International Union Against Cancer.

Objetivo: Determinar la significancia pronóstica de la razón ganglionar metastásica en la sobrevida a 5 años de pacientes luego de gastrectomía distal curativa por carcinoma gástrico avanzado. Materiales y métodos: Estudio de análisis de sobrevida que analizó información de 68 pacientes con adenocarcinoma gástrico avanzado resecable atendidos en el Instituto Regional de Enfermedad Neoplásicas Luis Pinillos Ganoza durante el período 2008-2013. Resultados: El número de ganglios linfáticos metastásicos osciló entre 0-29 (media: 3,9±5,8) y el número de ganglios linfáticos resecados comprendió los rangos de 13-66 (media: 35,34±12,60). No hubo correlación significativa entre el número de ganglios linfáticos metastásicos y el número de ganglios linfáticos extirpados (r=0,208, p=0,089). La sobrevida de la serie total a los 5 años fue de 55,9%. De acuerdo al estado ganglionar regional (N) de la 7ma edición de la UICC, los pacientes con N0 (n=27), pN1 (n=12), pN2 (n=17) y pN3 (n=12) mostraron tasas de sobrevida a los 5 años de 77,2%, 27,2%, 46,3% y 40% respectivamente (p=0,005). Los pacientes fueron estratificados en NR0 (razón 0%), NR1 (razón 1-59%) y NR2 (razón >60%). Sus tasas de sobrevida a 5 años fueron de 77,2%, 40,9% y 33,3% respectivamente (p=0,013). Conclusiones: La razón ganglionar metastásica constituye un sistema predictor de sobrevida actuarial a 5 años coherente en comparación con el estado ganglionar regional (N) del sistema de clasificación de la Unión Internacional Contra el Cáncer

[Impact of infectious postoperative complications in the long term survival of patients gastrectomized for gastric carcinoma with curative intent]. / Impacto de las complicaciones infecciosas postoperatorias en la sobrevida a largo plazo de pacientes gastrectomizados por carcinoma gástrico avanzado con intención curativa.

OBJECTIVE: To determine the impact of postoperative infectious complications in the long term survival of patients gastrectomized for gastric carcinoma with curative intent. MATERIALS AND METHODS: The present cohort study evaluated a series of 79 patients diagnosed with resectable advanced gastric carcinoma with curative intent. They were grouped in: Group A (N=28): patients with postoperative infectious complications and Group B (N=51): patients who did not develop postoperative infectious complications. The study covered the years 2008-2013. RESULTS: In group A, the survival rates at 1, 3 and 5 years was 74%, 74% and 47.6% respectively. In group B, the survival rates at 1, 3 and 5 years was 80.3%, 56% and 49.8% respectively (p=0.365). The main postoperative infectious complications not related to the surgical technique were pneumonia (20.3%), followed by urinary tract infection (3.8%). The main postoperative infectious complications related to surgical technique was sepsis (n=5), two of which were related to dehiscence esophagojejunal anastomosis, two bye gastroyeyunal fistula, another bye enterocutaneous fistula and one patient who presented abscess and necrosis peripancreatic's tissue. CONCLUSIONS: There was no impact on survival at 5 years in patients with postoperative infectious complications after gastrectomy with curative intent. However, further studies should be carried over.

Relación entre el tipo histológico según la localización tumoralenadenocarcinomagástricoavanzado resecable y su impacto en la sobrevida a 5 años. Instituto Regional de Enfermedades Neoplásicas - IREN Norte. 2008 ­ 2013 / Relationship between histological type according to tumor localization in advanced resectable gastric adenocarcinoma and its impact on survival to 5 years. Instituto Regional de Enfermedades Neoplásicas - IREN Norte. 2008 ­ 2013

Objetivo: Determinar la relación entre el tipo histológico según la localización tumoral en la sobrevida a 5 años de pacientes con carcinoma gástrico avanzado resecable. Material y métodos. El presente estudio analizó información de una serie de 95 pacientes. Los pacientes fueron agrupados de acuerdo al tipo histológico de la clasificación de Lauren y Jarvi en: tipo intestinal (n = 41), tipo difuso (n = 39) y mixto (n = 15), atendidos en el Instituto Regional de Enfermedades Neoplásicas IREN- Norte de Trujillo, periodo 2008 ­ 2013. Resultados: Las tasas de sobrevida a 5 años, en pacientes con adenocarcinoma gástrico de tipo histológico intestinal (n = 41) de acuerdo a la localización tumoral fueron de 60,6%, 47,1% y 0.0% ubicadas en cuerpo, antro y fondo respectivamente (p = 0,042). Las tasas de sobrevida a 5 años, en pacientes con adenocarcinoma gástrico de tipo histológico difuso (n = 39), de acuerdo a la localización tumoral fueron de 45,6% y 16.7% cuando las lesiones se ubicaron en cuerpo y antro gástrico respectivamente (p = 0.028). De acuerdo al tipo histológico mixto (n = 15) según localización tumoral, observamos que la sobrevida a 5 años de pacientes con lesiones en antro y cuerpo gástrico fueron de 68,2% y 50% respectivamente (p = 0,410). Conclusiones: El tipo histológico no constituye un factor pronóstico que tenga impacto en los resultados finales a largo plazo, sin embargo la localización tumoral al parecer si la tendría. Se hace necesario identificar con prontitud a otros factores clínicos, patológicos y moleculares de importancia pronóstica.

Objective: To determine the relationship between histological type according to tumor location and its impact on 5-year survival of patients with resectable advanced gastric carcinoma. Material and methods: This study analyzed data from a series of 95 patients. Patients were grouped according to histological type of Lauren classification and Jarvi in: intestinal type (n = 41), diffuse (n = 39) and mixed (n = 15), treated at the Regional Institute of Neoplastic Diseases IREN - North Trujillo, period 2008-2013. Results: Survival rates at 5 years in patients with gastric adenocarcinoma of intestinal histological type (n = 41) according to tumor location were 60.6%, 47.1% and 0.0% located in the body, antrum and background respectively (p = 0.042). Survival rates at 5 years in patients with diffuse gastric adenocarcinoma histology (n = 39) according to tumor location were 45.6% and 16.7% when the lesions were located in the gastric body and antrum respectively (p=0028).According to the mixed histology (n=15) according to tumor location, we note that the 5-year survival of patients with lesions in gastric antrum and body were 68.2% and 50% respectively (p = 0.410). Conclusions: The histological type is not a prognostic factor that impacts long-term end results, however apparently tumor location if you would. It is necessary to identify promptly to other clinical, pathological and molecular factors of importance forecast.
