RESUMEN

OBJECTIVE: Kidney cancer is around 2-3% of malignant tumours in adults. It has an important tendency to metastasize, being the most affected organs lungs, liver,brain, bone and adrenal glands. The pancreas is a rare site of kidney metastasis, with an incidence of 1-2.8%. The aim of this paper is to analyze the clinical diagnosis, treatment and prognosis of the pancreatic metastasis secondary to kidney cancer. METHOD: We present a retrospective descriptive analysis of 6 cases of pancreatic metastasis of primary kidney cancer diagnosed at Cruces University Hospital since 2011.We describe the cases individually also making a global analysis of the pathology and literature review. RESULTS: Two of the patients had pancreatic and extrapancreatic metastatic lesions, being treated systemic treatment without adjacent surgery. They showed an overall worse prognosis. The rest of the patients had only pancreatic disease,rational for surgical removal of all masses without need of further adjuvant treatment. The results after surgery were encouraging, with longer overall survival, progression free survival and better quality of life. CONCLUSIONS: Pancreatic metastases of kidney cancer are very rare and they can appear several years after nephrectomy. Patients with history of kidney cancer should be followed for long term after surgery. When metastases are limited to the pancreas, radical surgery has longer overall survival, progression free survival and better quality of life outcomes.

OBJETIVO: El cáncer renal constituye el 2-3% de los tumores malignos del adulto y tiene una gran tendenciaa metastatizar, siendo el pulmón, hígado, cerebro, hueso y suprarrenales los órganos diana más frecuentes. Sin embargo, también puede afectar a otros órganos más inusuales,como el páncreas, con una incidencia de 1-2,8%.El objetivo de este trabajo es analizar la presentación, tratamiento y pronóstico de las metástasis pancreáticas de cáncer renal.MÉTODO: Se realiza un análisis descriptivo retrospectivo de 6 casos de metástasis pancreáticas de tumor primario renal diagnosticados en el Hospital Universitario Cruces desde 2011. Se presentan los casos individualmente, se realiza un análisis global y revisión de la literatura. RESULTADO: En dos pacientes se objetivaron lesiones pancreáticas y extrapancreáticas, por lo que se decidió tratamiento sistémico, presentando estos pacientes un pronóstico peor. En el resto de los pacientes no se objetivó enfermedad extrapancreática, por lo que las lesiones pancreáticas se trataron quirúrgicamente, obteniendo una mejoría importante en la supervivencia, tiempo libre de enfermedad y calidad de vida, sin necesidad de tratamiento adyuvante. CONCLUSIONES: Las metástasis pancreáticas de cáncer renal son raras y pueden aparecer muchos años después de la nefrectomía, por lo que debería realizarse seguimiento a largo plazo en los pacientes con antecedentes de tumor renal. Cuando la enfermedad metastásica está limitada al páncreas, la cirugía radical mejora la supervivencia y calidad de vida de los pacientes.

RESUMEN

INTRODUCTION: A borderline resectable group (APBR) has recently been defined in adenocarcinoma of the pancreas. The objective of the study is to evaluate the results in the surgical treatment after neoadjuvancy of the APBR. METHOD: Between 2010 and 2014, we included patients with APBR in a neoadjuvant and surgery protocol, staged by multidetector computed tomography (MDCT). Treatment with chemotherapy was based on gemcitabine and oxaliplatin. Subsequently, MDCT was performed to rule out progression, and 5-FU infusion and concomitant radiotherapy were given. MDCT and resection were performed in absence of progression. A descriptive statistical study was performed, dividing the series into: surgery group (GR group) and progression group (PROG group). RESULTS: We indicated neoadjuvant treatment to 22 patients, 11 of them were operated, 9 pancreatoduodenectomies, and 2 distal pancreatectomies. Of the 11 patients, 7 required some type of vascular resection; 5 venous resections, one arterial and one both. No postoperative mortality was recorded, 7 (63%) had any complications, and 4 were reoperated. The median postoperative stay was 17 (7-75) days. The pathological study showed complete response (ypT0) in 27%, and free microscopic margins (R0) in 63%. At study clossure, all patients had died, with a median actuarial survival of 13 months (9,6-16,3). The median actuarial survival of the GR group was higher than the PROG group (25 vs. 9 months; p < 0.0001). CONCLUSION: The neoadjuvant treatment of APBR allows us to select a group of patients in whom resection achieves a longer survival to the group in which progression is observed. Post-adjuvant pancreatic resection requires vascular resection in most cases.

RESUMEN

INTRODUCTION: New parameters complementary to clinical TNM classification are needed, to orient preoperative on the possibility of a R0 gastric cancer resection. We analysed the possible predictive value of blood neutrophil/lymphocytic ratio (N/L) in relation to resectability. METHODS: Two hundred and fifty-seven gastric cancers consecutively diagnosed and without neoadjuvant treatment were retrospectively studied. Univariate and multivariate analysis of the frequency of R0 cases was performed between groups with a normal N/L ratio (<5) and pathological N/L ratio (≥5). Furthermore, we studied the subgroup of operated patients (n=156) analysing the frequency of R0 resection according to N/L ratio<5 or≥5. RESULTS: One hundred and fifty-six patients underwent surgical intervention, of which 139 had R0 resections. A high N/L ratio was registered in 46 cases (17.9%). Globally, resectability was higher in patients with a N/L ratio<5: 59.7% vs. N/L ratio≥5: 28.6% (P<.001; OR=3.76; 95% CI=1.78-8.04). The relation between N/L ratio<5 and R0 resection was confirmed in the multivariate (P=.006; OR=3.86; 95% CI=1.46-10.22). In the operated subgroup, the higher frequency of R0 resection achievement is maintained in cases with N/L ratio<5: 91.3% vs. 72.2% (P=.015; OR=4.04; 95% CI=1.23-13.26). CONCLUSIONS: The presence of a N/L ratio<5 at the diagnosis of a gastric carcinoma is related in a significant and independent way with a higher frequency of R0 tumoral resection, globally. This higher proportion of R0 resection cases in patients with a N/L<5 ratio is confirmed in the subgroup of operated patients.

RESUMEN

Introducción Los tumores periampulares son aquellos que se desarrollan en un área de 2 cm próxima de la papila de Vater; en este grupo se encuentran los tumores de cabeza de páncreas, los de la ampolla de Vater, los del colédoco intrapancreático y duodenales. Objetivo: Determinar la frecuencia de tratamiento quirúrgico curativo de los tumores de la región periampular en el servicio de Cirugía General del Hospital Central del Instituto de Previsión Social. Metodología: Investigación retrospectiva, observacional descriptiva y de corte transverso en el periodo 2009-2015. Resultados Se estudiaron 122 casos, la frecuencia de tumores periampulares resecables intraoperatoriamente, y por tanto sometidos a duodeno pancreatectomía cefálica fue de 38.52%, que corresponde a 47 casos del total. La relación de varón/mujer fue de 1,3/1. El promedio de edad fue 64,67 años. La ictericia fue el signo y síntoma prevalente y el primero en aparecer. Se realizó ecografía y tomografía en todos los pacientes. Ningún paciente fue sometido a ecoendoscopia. El tipo histológico más frecuente fue adenocarcinoma ductal de páncreas con 89 casos (72,95%). Conclusión: La estatificación quirúrgica determinando la resecabilidad o no de dichos tumores es fundamental para evitar procedimientos cruentos innecesarios, la ecografía y tomografía son estudios necesarios para la determinación de resecabilidad, pero que muchas veces necesitan ser reforzados con otros estudios como la eco endoscopia que evitaría los falsos resecables que ingresan a quirófano innecesariamente. Situación encontrada muy frecuentemente en este estudio.

Introduction: Periampullary tumors are most often localizated in a 2 cm area next to the ampulla of Vater, and this group included the head of pancreas carcinoma, Vater´s ampulla carcinoma, intrapancreatic cholangiocarcinoma and duodenal carcinoma. Objective: to define the frequency of curative surgical treatment in tumors of periampullar region at the Service of General Surgery of Instituto de Previsión Social. Patients and Method: a retrospective, observational and descriptive study between 2009 and 2015. Results: In 122 cases, 47 of them (38,5%) had a resectability criteria and was performed a CDP surgery in these cases. There wasn´t difference of presentation according to gender. The average age was 64,67 years old. Jaundice was the first symptom showed and the most common. It was performed ultrasonography and CT scan in all patients. The most common histological type was the pancreatic ductal adenocarcinoma in 89 patients. Conclusion: The staging of the periampullar tumors and the resectabilty criteria are very important parameters to avoid an unnecessary surgical procedure. Ultrasonography and CT scan are important tools to clarify the resectability criteria, even better if they are accompanied by endoscopic ultrasound.

RESUMEN

Demostrar que la cirugía de intervalo constituye una opción terapéutica efectiva en el aumento de la resecabilidad tumoral, mejorando la sobrevida de aquellas pacientes con tumores epiteliales de ovario clasificados como estadio III y catalogados como "no resecables". Estudio retrospectivo y descriptivo de las pacientes pertenecientes al servicio de ginecología del Hospital Oncológico "Padre Machado" con el diagnóstico de tumor epitelial de ovario clasificados como estadio III, incluidos en un protocolo de cirugía de intervalo, en el período septiembre 2002- septiembre 2007. Fueron identificadas 13 pacientes. El esquema de quimioterapia utilizado en todos los casos fue el de paclitaxel a dosis de 175mg/m² y carboblatino 5ABC, con una media de 4,46 ciclos. Se estableció una respuesta posterior a la quimioterapia primaria mayor al 50 por ciento 76,92 por ciento de los pacientes. La cirugía de intervalo aumenta el porcentaje de resecabilidad y disminuye el porcentaje de complicaciones posoperatorias, no evidenciándose beneficios estadísticamente significativos en términos de aumento de la sobrevida libre de enfermedad.

To demonstrate that interval debulking surgery constitutes an effective therapeutic option in the increase of the tumor like resected, improving the over life of those patients with epithelial tumors of ovary classified III stage, catalogued like “none resected”. Retrospective and descriptive study of the patients that assisted the service of gynecology of the Oncology Hospital “Padre Machado” with the diagnosis of epithelial tumor of ovary III stage, included in protocol interval debulking surgery, during the period September 2002-September 2007. 13 patients were identified. The scheme of chemotherapy used in all the cases was paclitaxel at dose of 175mg/m² and carboblatin 5ABC, with a media of 4.46 cycles. An answer greater than 50 % was settled down subsequent to the primary chemotherapy in a 76.92 % of the patients. The interval debulking surgery increases the percentage of respectability and diminishes the percentage of postoperative complications, not demonstrating itself significant benefits in terms of increase in the free disease period.
