RESUMO

Los liposarcomas son neoplasias malignas raras que se originan en el tejido adiposo, con mayor frecuencia en el retroperitoneo. De todas las variantes histológicas, el diferenciado es el más común y el de mejor pronóstico. El diagnóstico se establece con pruebas imagenológicas con o sin ayuda de biopsia. El tratamiento consiste en la resección completa del tumor, que puede o no acompañarse de terapia adyuvante. Se presenta el caso de un paciente de 41 años con distensión abdominal y pérdida de peso, en el que se confirma un liposarcoma retroperitoneal mediante una TC abdominal, por lo que fue sometido a una resección quirúrgica completa que resultó exitosa. El paciente se recuperó satisfactoriamente y se mantuvo sin recidivas durante el seguimiento. Se concluye que el diagnóstico y terapéutico varían de acuerdo con las características del tumor y su riesgo de recidiva; por lo que hasta la actualidad continúa siendo un desafío multidisciplinario.


SUMMARY Liposarcomas are rare malignant neoplasms that originate in adipose tissue, most frequently in the retroperitoneum. Of all histological variants, differentiated liposarcoma is the most common and has the best prognosis. Diagnosis is established by imaging tests with or without the aid of biopsy. Treatment consists of complete resection of the tumour, which may or may not be accompanied by adjuvant therapy. We present the case of a 41-year-old patient with abdominal distension and weight loss, who was confirmed to have retroperitoneal liposarcoma by abdominal CT scan and underwent successful complete surgical resection. The patient recovered satisfactorily and remained free of recurrence during follow-up. It is concluded that diagnosis and therapy vary according to the characteristics of the tumour and its risk of recurrence, which is why it remains a multidisciplinary challenge to this day.

RESUMO

Anastomotic leakages at the gastrojejunostomy site are difficult to repair, due to complex gastrointestinal anatomy. This is the first study reporting clinical use of rectus abdominis muscle (RAM) flap for repair of gastrojejunostomy leakage. A patient with leakage of gastrojejunostomy after distal gastrectomy with Billrroth II anastomosis for gastric cancer underwent repair using left RAM flap, based on superior epigastric artery. Rectus abdominis muscle flap, after being harvested was then anchored to the edges of the leak of gastrojejunostomy with few interrupted 2-0 vicryl sutures. Gastrojejunostomy leak sealed in the two cases. Rectus abdominis muscle flap for closure of gastrointestinal defect is a simple, technically easy and dependable procedure, which can be performed, quickly in critically ill patients. It can be used for repair of a large gastrointestinal defect with friable edges when omentum is not available or when other conventional methods are impractical.

Las dehiscencias anastomóticas en el sitio de gastroyeyunostomía son difíciles de reparar, debido a la compleja anatomía gastrointestinal. Este es el primer estudio que comunica el uso clínico del colgajo del músculo recto abdominal (MRA) para la reparación de la dehiscencia de gastroyeyunostomía. A un paciente con dehiscencia de gastroyeyunostomía, luego de una gastrectomía distal con anastomosis Billrroth II para cáncer gástrico, se le realizó una reparación utilizando colgajo izquierdo del MRA, basado en la arteria epigástrica superior. El colgajo del músculo recto abdominal, después de ser extraído, se fijó a los bordes de la dehiscencia de la gastroyeyunostomía con pocas suturas de vicryl 2-0 interrumpidas. La dehiscencia de la gastroyeyunostomía fue sellada. El colgajo del músculo reto abdominal para el cierre del defecto gastrointestinal es un procedimiento simple, técnicamente fácil y confiable, que puede realizarse rápidamente en pacientes críticamente enfermos. Se puede utilizar para la reparación de un gran defecto gastrointestinal con bordes friables cuando el omento no está disponible o cuando otros métodos convencionales no son prácticos.

RESUMO

Objetivo: Identificar los principales factores predictivos de recurrencia luego de gastrectomía por carcinoma gástrico avanzado resecable. Material y métodos: Estudio de casos y controles analizó información de una serie total de 61 pacientes con diagnóstico anatomopatológico de carcinoma gástrico resecable atendidos en Instituto Regional de Enfermedades Neoplásicas del Norte "Luis Pinillos Ganoza" de Trujillo - Perú, periodo de enero del 2008 al diciembre del 2015. Resultados: Se evaluaron un total de 61 historias clínicas, las cuales se agruparon en casos (n = 14) y controles (n = 47). Del total de 61 pacientes, en 14 (22,9%) de ellos se observó recurrencia de enfermedad, con un tiempo promedio de recurrencia de 24.02 meses ± 15,95 meses (rango: 2,60 ­ 64,40 meses). Se determinó recurrencia de tipo distante en 7 pacientes, el siguiente tipo de recurrencia fue la recurrencia peritoneal en 04 pacientes, finalmente el tipo de recurrencia locorregional solo se presentó en 04 casos. Conclusiones: No hubo diferencias significativas entre los factores de riesgo clínicopatológicos - quirúrgicos evaluados y la recurrencia luego de cirugía por carcinoma gástrico avanzado resecable. Sin embargo, hubo diferencias estadísticamente significativas en la tasa de sobrevida a 5 años en los pacientes que presentaron recurrencia de aquellos que no.


Objetive: To identify the main predictors of recurrence after gastrectomy for resectable advanced gastric adenocarcinoma. Material and methods: Case-control study analyzed information from a total series of 61 patients with an anatomopathological diagnosis of resectable gastric adenocarcinoma treated at the Regional Institute of Neoplastic Diseases of the North "Luis Pinillos Ganoza" of Trujillo - Peru, from January 2008 to December 2015. Results: A total of 61 clinical histories were evaluated, which were grouped into cases (n = 14) and controls (n = 47). Of the total of 61 patients, disease recurrence was observed in 14 (22.9%) of them, with an average recurrence time of 24.02 months ± 15.95 months (range: 2.60 - 64.40 months). Recurrence of distant type was determined in 7 patients, the next type of recurrence was peritoneal recurrence in 04 patients , finally the type of locoregional recurrence only occurred in 04 cases. Conclusions: Therewere no significant differences between the clinical - pathological risk factors evaluated and the recurrence after surgery for resectable advanced gastric carcinoma. However, there were statistically significant differences in the 5year survival rate in the patients who presented recurrence of those who did not.

RESUMO

OBJECTIVE: To evaluate the diagnostic validity of fine-needle capillary cytology (FNCC) in palpable tumours. MATERIAL AND METHODS: A retrospective, single-tray, cross-sectional diagnostic test study was carried out. We reviewed the cytological reports of the case files of the Cytology Unit of the Northern Regional Institute of Neoplastic Diseases (IREN) from January 2012 to December 2016. RESULTS: A total of 332 patients were selected, with an average age of 54.77 years (range 13-90 years); 61.4% of patients were female. The most frequent anatomical sites were lymph nodes (49.7%), thyroid (13.3%), breast (12.3%) and soft tissues (11.4%). Twenty-five cytologies did not have a histological correlation and six showed an atypical result. In the lymph node study, the most frequent pathology was metastatic carcinoma (49.7%), followed by lymphoma (13.3%). The FNCC had a sensitivity of 99.55%, a specificity of 98.77%, a positive predictive value of 99.55% and a negative predictive value of 98.77%. The positive likelihood ratio was 80.63%. CONCLUSIONS: FNCC is a useful, safe, reliable and economical ambulatory technique with minimal complications and high diagnostic accuracy.

RESUMO

Objetivo: Describir y comparar las características clínico anatomopatológicas, pronóstico y sobrevida a 5 años en carcinoma gástrico resecable con linfadenectomia D2 con diámetro tumoral < 10 cm. (SG1) y >10 cm. grande (Sg2). Material y métodos: Cohorte que analizó a 139 pacientes con carcinoma gástrico avanzado con diámetro tumoral < 10 cm (n = 120) y grande resecable > 10 cm (n = 19) con linfadenectomía D2 atendidos en el Instituto Regional de Enfermedades Neoplásicas del Norte, durante el periodo 2009-2014. Resultados: La edad media en el SG1 fue de 60,91 + 13,06 años, mientras que en SG2, fue de 64,84 + 15,01 años respectivamente. En el SG1 los factores pronósticos asociados a la sobrevida fueron el tumor primario (p = 0.007), estado ganglionar regional (p = 0.0001), estadio clínico (p = 0.0001) y el tipo histológico (p = 0.028). En el SG2 las características anatomopatológicas fueron en mayor frecuencia, localización tumoral en el tercio inferior (52,6%), Borrmann III (31,6%), tumor primario T4a (47,4%), estado ganglionar N3b (36,8%), estadio clínico III (78,9%) y tipo intestinal difuso (47,4%). La tasa de sobrevida global a 5 años para el SG1 y SG2 fue 42% vs 13,6% respectivamente (p = 0,001). Conclusiones: Las características clínicas y anatomopatológicas fueron similares en ambos grupos de estudio independientemente del tamaño del tumor. Sin embargo hay diferencia estadísticamente significativa con relación a la sobrevida a 5 años, por lo que este factor pronóstico importante que debería ser incluido en este sistema para una mejor estratificación y manejo individualizado de pacientes.

RESUMO

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.

RESUMO

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.

RESUMO

Objetivo: Comprobar el impacto de las complicaciones infecciosas postoperatorias en la sobrevida a largo plazo de pacientes gastrectomizados por carcinoma gástrico con intención curativa. Materiales y métodos: El presente estudio de cohortes evaluó una serie de 79 pacientes con diagnóstico de carcinoma gástrico avanzado resecable con intención curativa. Se agruparon a su vez: Grupo A (N=28): Pacientes con complicaciones infecciosas postoperatorias y Grupo B (N=51): Pacientes que no presentaron complicaciones infecciosas postoperatorias. El estudio abarcó los años 2008-2013. Resultados: En el grupo A, las tasas de sobrevida a 1, 3 y 5 años fueron de 74%, 74% y 47,6% respectivamente. En el grupo B, las tasas de sobrevida a 1, 3 y 5 años fueron de 80,3%, 56% y 49,8% respectivamente (p=0,365). Las principales complicaciones infecciosas postoperatorias no relacionadas con la técnica quirúrgica fue la neumonía (20,3%), seguida de infección del tracto urinario (3,8%). Las principales complicaciones infecciosas postoperatorias relacionadas con la técnica quirúrgica fue la sepsis (n=5), dos de estos pacientes presentaron de dehiscencia de anastomosis esofagoyeyunal, dos presentaron fístula gastroyeyunal, uno fístula enterocutánea y por último un paciente presentó absceso y necrosis de tejido peripancreático. Conclusiones: No hubo un impacto en la sobrevida a 5 años en pacientes con complicaciones infecciosas postoperatorias post gastrectomía con intención curativa. Sin embargo, más estudios adicionales deberían efectuarse.

RESUMO

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.

Objetivo: Conocer la efectividad del puntaje de Estimación de la Capacidad Fisiológica y Estrés Quirúrgico Modificado (mE-PASS) en la predicción de la morbimortalidad postoperatoria de pacientes con carcinoma gástrico avanzado resecable atendidos en el Departamento de Cirugía Abdominal del Instituto Regional de Enfermedades Neoplásicas del Norte "Luis Pinillos Ganoza" durante el período 2008 ­ 2011. Material y Métodos: Se realizó un estudio de cohortes, retrospectivo, observacional, longitudinal, correlacional y cuantitativo, para evaluar el instrumento "Estimación de la Capacidad Fisiológica y Estrés Quirúrgico Modificado" (mE-PASS) para carcinoma gástrico operado. Resultados: Se evaluaron a 41 pacientes, 17 (41,5%) varones y 24 (58,5%) mujeres con una edad media 61.1 ± 14,26 (rango: 30 ­ 85 años). Hubo 14 pacientes complicados (34,1%) y un sólo caso de mortalidad postoperatoria. El instrumento evaluado discrimina adecuadamente los complicados de los no complicados (ROC de 76,8% I.C.95%: 0,635 ­ 0,937 p = 0,0003). El puntaje de riesgo global modificado (CRSf) mayor e igual a 0,5 puntos presentaron una frecuencia de complicaciones mayor en comparación con aquellos con CRSf menor (54.5% vs. 10,5% respectivamente; RR: 5,18; I.C. 95%: 1,32 ­ 20,30 p = 0,003069). Existió un sólo caso de mortalidad por lo cual no se pudo determinar la calibración del instrumento para mortalidad. Conclusión: El instrumento es efectivo y logra discriminar el riesgo de morbilidad de los pacientes postoperados de carcinoma gástrico en el IREN Norte durante el periodo 2008 ­ 2011.

RESUMO

OBJECTIVE: To determine trends in the prevalence and identify the main risk factors associated with the development of pancreatic cancer. MATERIALS AND METHODS: Study of trends in incidence and case-control population consisted of a total of 134 patients. Patients were grouped into: a) CASES: 67 patients diagnosed with pancreatic cancer treated at the Abdomen's Service of the Specialized Surgery Department of the Regional Institute of Neoplastic Diseases "Dr. Luis Pinillos Ganoza "- IREN North during the period 2008 to 2011; and b) CONTROLS: 67 patients diagnosed with gallstones and / or benign biliary disease treated at Belen Hospital in Trujillo during the period 2008 to 2011. RESULTS: The trend curve of incidence of pancreatic cancer showed a curve almost constant throughout the quadrennium 2008 to 2011, with incidence rates of 5.38%, 5.08%, 5.5% and 5.0% respectively. The overall incidence was 5.37%. The trend function was Y = (1756) ± (0.001) (x), with an R2 = 0.318 (p = 0.436). The main risk factors associated with pancreatic cancer were age bigger and equal to 60 years (p = 0.0001), male sex (p = 0.007), diabetes mellitus (p = 0.002) and family history of malignancy (p = 0.016). CONCLUSIONS: The trend in incidence in pancreatic cancer was low and constant in its appearance was significantly influenced by age, gender, and presence of diabetes mellitus and family history of cancer.

RESUMO

OBJECTIVE: Determine the effectiveness of surgical treatment and / or adjuvant to improve the quality of life in patients with colon cancer compared to rectal cancer. MATERIAL AND METHODS: Cohort study that evaluated 27 patients diagnosed with colon adenocarcinoma (Group A= 12) and rectum (Group B= 15) resectable treated at the Institute Regional of Neoplastic Diseases of Trujillo since the 1 January 2008 until 31 July 2009. RESULTS: The overall life quality, as assessed by the QLQ-C 30 at 3 months postoperatively was 67.86 +/- 17.90 points vs. 68.50 +/- 11.94 points respectively for the patients of groups A and B (p = 0.934).The social function was better in patients undergoing surgery for Group A than Group B , (37.50 + 13.36 points vs. 60.00 + 13.69 points, p = 0.018). Body image at 3 months assessed by the QLQ-CR-29 had an average score of 28.12 +/- 6.12 points and 50.00 +/- 25.00 points for Group A y B respectively (p = 0.034). The Group A patients had a mean score at 6 months for sexual function of 33.33 +/- 12.91 points, while Group B patients this average score was 65.00 +/- 22.36 points (p = 0.016). CONCLUSIONS: Both surgeries for colon and rectal cancer are as effective in improving the overall quality of life of these patients, however the social function, body image, and sexual function is better in colon surgery.

RESUMO

Objetivo. Determinar la efectividad del tratamiento quirúrgico y/o adyuvante en mejorar la calidad de vida en pacientes con cáncer de colon en comparación al de cáncer rectal. Material y Métodos. Estudio de cohortes ambispectivo que evaluó 27 pacientes con diagnóstico de adenocarcinoma de colon (Grupo A=12) y de recto (Grupo B= 15) resecable atendidos en el Instituto Regional de Enfermedades Neoplásicas de Trujillo desde el 1 de enero 2008 hasta el 31 de julio del 2009. Resultados. La calidad vida global, valorada por el cuestionario QLQ-C30 a los 3 meses del postoperatorio fue de 67.86 más menos 17.90 puntos vs. 68.50 más menos 11.94 puntos respectivamente para los pacientes del grupos A y B (p = 0.934). La función social fue mejor en pacientes sometidos a cirugía en el Grupo A que en el grupo B (37.50 +/- 13.36 puntos vs. 60.00 +/- 13.69 puntos; p = 0.018). La imagen corporal a los 3 meses valorada por el cuestionario QLQ-CR-29 tuvo una puntuación media de 28.12 +/- 6.12 puntos y 50.00 +/- 25.00 puntos para los pacientes del Grupo A y B respectivamente (p = 0.034). Los pacientes del Grupo A presentaron una puntuación promedio a los 6 meses para la función sexual de 33.33 +/- 12.91 puntos, mientras que los pacientes del Grupo B su puntuación promedio fue 65.00 +/- 22.36 puntos (p = 0.016). Conclusiones. Ambas cirugías para cáncer de colon y recto tienen la misma efectividad en mejorar la calidad de vida global de dichos pacientes, sin embargo la función social, imagen corporal, y función sexual es mejor en cirugía de colon.
