ABSTRACT
Introducción: El trasplante renal constituye la modalidad terapéutica que ofrece mayor calidad de vida y supervivencia a los pacientes con enfermedad renal crónica y la mejor alternativa económica para enfrentar esta epidemia. Objetivo: Conocer el comportamiento clínico-epidemiológico del trasplante renal en los casos de donante vivo. Métodos: Se realizó un estudio observacional descriptivo de cohorte, retrospectivo, de los pacientes que recibieron trasplantes de donante vivo en el Instituto de Nefrología de 1991-2008. Para ello se utilizaron variables que se procesaron en forma automatizada con una técnica estadística de análisis de distribución de frecuencias absolutas y relativas así como técnicas de análisis de supervivencia mediante el método de Kaplan-Meier. Se estimó supervivencia para el injerto y para el paciente. Fueron estudiados 102 pacientes. Resultados: Los años de más realización de trasplantes fueron entre el 2000 y el 2004. Las causas de enfermedad renal crónica que predominaron fueron las glomerulopatías (47,1 por ciento) y las no filiadas (29,4 por ciento), sobre todo entre los 20 y 49 años. El trasplante precoz se realizó en 44,1 por ciento de los casos. Predominó el trasplante entre hermanos (49 por ciento) y de madres a hijos (35,2 por ciento). Se presentan las supervivencias del injerto y del paciente a corto, mediano y largo plazo. Conclusiones: El trasplante de donante vivo se efectúa, sobre todo, a receptores jóvenes que llegan a la insuficiencia renal por glomerulopatías o causas desconocidas. Su supervivencia es adecuada aunque existe una relativa alta incidencia de complicaciones quirúrgicas y muerte del paciente en el primer año, quizás relacionada con el bajo número de trasplantes por año
Introduction: The renal transplantation is the therapeutical modality offering the better quality of life and survival for patients presenting with chronic renal disease and the better economic alternative to face this epidemics. Objective: To know the clinical-epidemiological behavior of renal transplantation in the case of live donor. Methods: A retrospective, cohort, descriptive and observational study was conducted in patients underwent transplants from live donors in the Institute of Nephrology from 1991 to 2008. Authors used the variables processed in a automated way with statistical technique of analysis of absolute and relative frequency distribution, as well as techniques of survival analysis by Kaplan-Meier method. For the graft and for the patient survival was estimated. One hundred two patients were studied. Results: The year with more carrying out of transplantation were 2000 and 2004. The predominant causes of chronic renal disease were the glomerulopathies (47.1 percent) and the non-descripted ones (29.4 percent) mainly between 20 and 49 years old. The early transplantation was performed in the 44.1 percent of cases. There was predominance of transplantation between brothers (49 percent) and from mothers to sons. The survival of graft and of patient at short- medium- and long-term is showed. Conclusions: The life donor transplantation is carried out mainly in young receptors arriving to renal failure due to glomerulonephritis or by unknown causes. Its survival is appropriate although there is a relatively high incidence of surgical complications and death of patient during the first year, perhaps related to the low number of transplantation by year

PURPOSE: The aim of this study is to evaluate the clinicopathological features and treatment results of 49 cases of gastric stump cancer based on the classification proposed by the Korean Gastric Cancer Association. METHODS: A total of 49 patients with gastric stump cancer, who underwent operation from 1991 to 2000, were divided into three group: primary cancer (group I, n=20), remnant cancer (group II, n=15) and recurrent cancer (group III, n=14). The clinicopathological features and patient survivors in each groups were analyzed and compared with the primary upper one third cancer patients. RESULTS: The incidence of operated stump cancer was 0.8% (49/6, 445 cases) during the ten years. The male to female ratio was 3.9: 1 and mean age was 56.5 years (range 39~ 83 years). The resectability was 96% (47/49 cases) and curability was 73.4% (36/49 cases). There were 16 (80%), 1 (7%), 0 (0%) cases of benign primary disease and 4 (20%), 14 (93%), 14 (100%) cases of malignant primary disease in each group, respectively. The mean duration from primary disease to stump cancer was 21.7 years (10~40 years) in group I, 3.4 years (4 months~9 years 2 months) in group II and 3.4 years (1 year~7 years 5 months) in group III. The 5 year-survival rate was 45.1% in group I, 63.5% in group II and 0% in group III. But there was no statistic differences in 5 year-survival rates between stump cancer (33.0%) and primary cancer of the upper one third (30.9%). CONCLUSION: The condition of the primary disease, tumor location, duration of cancer development and tumor stage had statistical differences between the three groups. In the case of benign disease, the patients belonged in the high-risk group for the new development of gastric cancer following 20 years. Early detection of cancer in the remnant stomach by periodic follow up is important, especially in high-risk groups, and application of aggressive surgical treatment will improve patient survival.

The influence of age and menopausal status at diagnosis on the prognosis of patients with primary breast cancer remains controversial. Some studies have found that younger patients have worse clinical outcomes than older patients, others have reported that younger patients have a more favorable outcome, and others have found no relation with age. We analyzed the effects of menopausal status in the survival of patients with operable breast cancer and estimated the correlations between the menopausal status and other established prognostic factors. We reviewed the records of the patients who had been operated on at the Department of Surgery, Hangang Sacred Heart Hospital, College of Medicine, Hallym University during the past 10 years (1985~1996). The results were as follows: 1) The peak age group was the fifth decade (27%), and all of patients, except one, were females. 2) The most common symptom was a palpable breast mass with or without pain (88%). 3) Most patients (72.8%) visited within 6 months of the first appearance of a symptom, and the most frequent tumor size was 2~5 cm in diameter (58.9%). 4) Most of the primary tumors were located in the upper outer quadrant (61%); tumors located in the lower outer quadrant were rare (3%). 5) The most common TNM stage group was stage II (54.1%), and there was no difference of distribution between the premenopause and the postmenopause groups. 6) The common pathologic cancer types were infiltrating ductal cancer (73.8%), medullary cancer (9.3%), mucinous cancer (8.3%). 7) Axillary lymph-node metastasis was present in 58 cases (62.4%). 8) The overall five-year survival rate for all patients was 43.9%. 9) The five-year survival rates of the 38 premenopausal patients and the 38 postmenopausal patients were 42.4% and 35.8%, respectively, but there was no statically significant difference between the two groups. 10) Menopausal status did not significantly correlated with tumor size, tumor location, lymph-node metastasis or TNM stage. In conclusion, the menopausal status may be not correlated with the prognosis in breast cancer However, the effect of menopausal status on the prognosis of patients with breast cancer needs to be investigated for a large papulation of breast cancer patients.
