Neoplasias primarias malignas múltiples en pacientes con cáncer gástrico en el área sanitaria de León / Multiple malignant primary neoplasms in patients with gastric neoplasms in the health district of León

Objetivos: analizar las características de los pacientes con tumores gástricos diagnosticados de una neoplasia primaria maligna múltiple (NPMM) en el área sanitaria de León. Pacientes y método: utilizando los datos del Registro de Tumores del Hospital de León se han seleccionado aquellos pacientes con tumores gástricos diagnosticados entre 1993 y 2002. Se realizó un seguimiento hasta el 31 de diciembre de 2004 analizando las características de los pacientes diagnosticados de una segunda neoplasia durante el periodo de seguimiento. Resultados: la prevalencia de NPMM fue del 1,96%. El 56% de los pacientes tenían antecedentes oncológicos en familiares de primer grado. Las segundas neoplasias más frecuentes fueron las digestivas (26%) y las urológicas (21%). El 87% de los pacientes fueron diagnosticados del segundo tumor en los primeros dos años. No se observaron diferencias respecto a la supervivencia entre los pacientes con NPMM sincrónicas y metacrónicas. Conclusiones: las NPMM en los pacientes con cáncer gástrico son un problema relevante. Aunque los agentes carcinógenos externos puedan actuar como promotores en el desarrollo de una segunda neoplasia, en estos pacientes parece existir una base genética que favorece el desarrollo del una NPMM. La prevención secundaria es la mejor medida para evitar el desarrollo de una NPMM

Objectives: we analyzed the characteristics of patients with gastric tumors diagnosed with multiple malignant primary neoplasm (MMPN) in the Health District of León. Material and methods: using the information in the Tumor Registry at León Hospital patients selected were those with gastric neoplasms diagnosed between 1993 and 2002. A follow-up was performed until December 31, 2004, and the characteristics of patients diagnosed with a second neoplasm were analyzed. Results: MMPN prevalence was 1,96%; 56% of patients had a history of cancer in first-degree relatives. The most frequent second neoplasms were digestive (26%) and urologic (21%); 87% of patients were diagnosed with a second neoplasm within the first two years. No significative differences in survival were observed among patients with synchronous or metachronous MMPN. Conclusions: MMPN in patients with gastric neoplasms is a relevant problem. While external carcinogenic agents could act as promoters in the development of second neoplasms, these patients seem to have a genetic background favoring the development of MMPN. Secondary prevention is the best measure to avoid MMPN development

[Analysis of the characteristics of patients with bladder cancer diagnosed of multiple neoplasms in the health district of León (Spain)]. / Análisis de las características de los pacientes con cáncer vesical diagnosticados de neoplasias múltiples en el área sanitaria de León.

OBJECTIVE: We analyzed the characteristics of the patients with bladder neoplasms who developed a multiple malignant primary neoplasm (MMPN) in the health district of León, the impact on survival and the prognostic variables. MATERIAL AND METHODS: We have used the data from the Tumor Registry of the Hospital of León and selected all those patients who were diagnosed of a bladder tumor between 1993 and 2002. They were classified into two groups: the first with 71 patients with MMPN and a second group with 159 patients with single bladder tumors diagnosed between 1996 and 1997. RESULTS: Incidence of MMPN was of 7.1 percent. More than half of the patients had familial oncologic background. The second most frequently diagnosed neoplasms were urologic, followed by gastrointestinal and respiratory. Survival of patients with MMPN was 21 percent lower than single neoplasms. Variables with prognosis significance were the stage of the second neoplasm, diagnosis of a second urologic neoplasm and surgery treatment for the second tumor. CONCLUSIONS: MMPN in patients with bladder tumors are frequent in our geographic area. The high frequency of familial oncologic antecedents in these patients suggest a genetic background. Prognosis of MMPN patients is worse than single tumors patients, but no differences were observed regarding prognosis in patients with synchronous or metachronous MMPN.

Cáncer colo-rectal multicéntrico (CCRM) en el área sanitaria de León / Multicentric colo-rectal cancer (MSCC) in the health district of León

Objetivos: Analizar las características de los pacientes diagnosticados de CCRM en el área sanitariade León, el impacto sobre la supervivencia y las posibles variables pronósticas.Material y métodos: Utilizando los datos del Registro de Tumores del Hospital de León se hananalizado las características de aquellos pacientes con tumores colo-rectales diagnosticados entre 1993y 2002, clasificándolos dos grupos: el primero constituido por 74 pacientes diagnosticados de CCRMy el segundo formado por 1342 pacientes con tumores únicos diagnosticados en el bienio 1996-1997.Resultados: La frecuencia de CCRM fue del 2,7%. La edad de los pacientes con CCRM fue 2años mayor con respecto a la de los pacientes con neoplasias únicas, con una elevada proporción(38%) de antecedentes familiares oncológicos en familiares de primer grado. No se observaron diferenciassignificativas en cuanto a la localización y el estadio del primer tumor colo-rectal con respectoal grupo de tumores únicos. La supervivencia de los pacientes con CCRM metacrónico fue netamenteinferior, posiblemente en relación con un mayor número de segundas neoplasias diagnosticadas en estadiostempranos en los pacientes con CCRM sincrónico. Las variables que influyeron en el pronósticofueron la edad, el sexo, y el padecimiento de un CCRM sincrónico o metacrónico.Conclusiones: El CCRM es una entidad frecuente en nuestro medio. La tasa de antecedentes familiaresoncológicos en estos pacientes es muy elevada. No se encontraron diferencias significativasen cuanto al pronóstico de estos pacientes respecto al de los pacientes con neoplasias únicas

Purpose: We analyze the characteristics of patients with multicentric colo-rectal cancer (MCRC)in the health district of León, the impact on survival, and the prognostic variables.Material and methods: : Using the data from the Hospital de León Tumour Registry, weanalyzed the characteristics of all the patients diagnosed of having colo-rectal tumours between 1993and 2002. The patients were classified in two groups: one of them composed by 74 patients with MCRC,and the other formed by 1342 patients diagnosed in 1996 and 1997 of having single colo-rectal tumours.Results: The observed frequency of MCRC corresponded to 2.7 percent of the whole cases. Theage of the MCRC patients was 2 years higher than that of the patients with single neoplasms, andshowed a higher familial oncologic history, that was present in 38 percent of the cases. No differenceswere observed for location and stage of the first appeared colo-rectal neoplasm. The survival of thepatients developing metachronous MCRC was lower than for those with synchronous disease,possibly due to the higher number of the second neoplasms appearing in these patients at early stages.Prognostic values were age, sex, and metachronous or synchronous type of disease.Conclusions: MCRC is a frequent entity. The frequency of familial oncologic history is veryhigh. No significant differences were seen in relation to prognosis between single and multiple colorectalcancer

[Multiple malignant neoplasms in patients with prostate tumours in the health district of Leon]. / Neoplasias malignas múltiples en pacientes con cáncer de próstata en el área sanitaria de León.

OBJECTIVE: We analyze the characteristics of the patients with prostate tumours who developed a multiple malignant primary neoplasms (MMPN) in the health district of León, the impact on survival and the prognostic variables. MATERIAL AND METHODS: We have used the data from the Tumour Registry of the Hospital of León and we have selected all those patients who were diagnosed of a prostate tumor between 1993 and 2002. Later we made two groups: the first with 67 patients with MMPN and a second group with 145 patients with single prostate tumours diagnosed during 1996 and 1997. RESULTS: Prevalence of MMPM was of 5.57 percent. Patients with MMPN were 3 years younger than those with single tumours, with a high frequency (41 percent) of familial oncologic antecedents on first degree parents. The more frequent association was the synchronous urologic neoplasm. During the next two years from diagnosed of prostate tumour, 86 percent of patients with MMPN were diagnosed of their second neoplasm. Survival of metachronous MMPN patients was lower than synchronous MMPN patients, being the variables with prognosis significance the age, metachronous MMPN, stage of second neoplasms and if the second neoplasms was or not urologic. CONCLUSIONS: MMPN in patients with prostatic tumours are frequent in our medium. A genetic base may be associated in these patients. Prognosis of metachronous MMPN patients is worse. No differences were observed about prognosis with single tumour patients.
