ABSTRACT

El compromiso hepático por tuberculosis es una presentación rara de la enfermedad. Su espectro clínico es variado; siendo una de las formas el tuberculoma hepático o tuberculosis pseudotumoral entidad poco frecuente que no muestra sintomatología específica, por lo que es difícil diagnosticarla. Se reporta el caso de un paciente con tuberculosis hepática pseudotumoral, cuyos síntomas de presentación fueron dolor en hipocondrio derecho y pérdida de peso. La tomografía computarizada mostró presencia de una lesión hepática sólida hipodensa que captaba sustancia de contraste de forma heterogénea. Fue sometido a hepatectomia segmentaria con la sospecha clínica de neoplasia maligna, sin embargo el estudio anatomopatológico confirmó el diagnóstico de tuberculosis. No se encontró foco primario en otras localizaciones. El paciente posteriormente recibió tratamiento antibiótico específico y evolucionó clínicamente bien.

ABSTRACT

INTRODUCTION: In Japan, endoscopic mucosal resection and endoscopic submucosal dissection of early gastric cancer are accepted as a treatment options for cases of early gastric cancer where the probability of lymph node metastasis is nil or low. OBJECTIVES: To establish the effectiveness of mucosectomy for the treatment of early gastric cancer and evaluate the extended indications for dysplasia lesions, also, we want to determine if the mucosectomy is relevant for lesions negative for neoplasia at the National Institute for Neoplastic Diseases (INEN), Lima, Peru. We call for estimating the utility and factibility of the endoscopic submucosa dissection with the needle knife. MATERIALS AND METHODS: The study is an observational, prospective, analytical and cross longitudinal. The study was performed in 96 patients with Type 0 Neoplastic lesions at INEN from 1996 to 2008. The revised Vienna classification of gastrointestinal epithelial neoplasia was utilized. The indication for endoscopic mucosal resection as a radical treatment of early gastric cancer is according to the treatment guidelines for gastric cancer in Japan. The lesions were resected with a simple endoscopic snare, with the Olympus cap for some depressed lesions and the needle knife during the submucosal dissection. Lifting of the lesion with submucosal injection was done with saline solution with epinephrine or saline with distillate water. The statistical analysis included the SPPS-12 programme. RESULTS: 96 patients were treated by mucosectomy and endoscopic submucosal dissection from 1996 to 2008. The sample represents patients with a mean age over 50 years old and predominance of female. 55 patients belongs to category 1 of revised Vienna Classification, 9 patients are in the category 3, 31 patients are suitable in category 4 (20 with high grade adenoma/dysplasia and 11 with intramucosal carcinoma) and just 1 patient for the category 5. We resected 305 Type 0 lesions, 85 mucosal neoplasia, low grade (43) and high grade (31 adenoma/dysplasia in 20 patients and 11 intramucosal carcinoma in 11 patients), and 219 lesions negatives for neoplasia. Approximately 200 lesions were resected by mucosectomy. The endoscopic submucosal dissection was done in 03 patients with additional mucosectomy. In general, the complications were bleeding resolved during the same procedure; there were no perforations in the current series. The local recurrence of 2 adenomas (high and low dysplasia), were resolved with Plasma Argon. We have no evidence of neither local nor distant recurrence in patients with intramucosal carcinoma in 5-10 years follow up. The patient treated by mucosectomy and submucosal invasion was operated and his actual survival is 6 years and 7 months. CONCLUSIONS: Mucosectomy is effective for precise variety of early gastric cancer with a median follow up period of 5-10 years in ours first patients, preserve the organ and maintain a high quality of life. Mucosectomy is appropriated for mucosal low and high grade adenoma/dysplasia, the local recurrence can be treated by Plasma Argon. The procedure can extend the indications eventually for lesions that are non-neoplasia. The endoscopic submucosal dissection must be done only in trained centres.

ABSTRACT

Classic Kaposi s sarcoma (KS) affects lower extremities in older adults, showing a progressive, benign course. It can also involve oral mucosa and gastrointestinal tract with a lower frequency. The involvement of internal organs and lymph nodes is rare, and its primary compromise is even more uncommon. We report an unusual presentation of classic KS in the lymph nodes of three patients. A 46 years old male had a primary involvement of an inguinal lymph node. Dermal involvement appeared one year later. A 58years old male and a 76years old female with simultaneous dermal and lymph node involvement. We conclude that the presence of classic KS in our region is more common than previously considered. Moreover, it must be emphasized that KS in lymph nodes can affect HIV-negative patients or patients without any associated immune deficiency.

ABSTRACT

INTRODUCTION: The colonics polyps according to their number, size, location, age of presentation and mainly, according to their histology, have the potentiality of malignant degeneration, which makes of a continuous study and pursuit susceptible. OBJECTIVES: To evaluate the relation between the histologic type of the colon polyps, its location, the degree of dysplasia, the size, its possible commitment by carcinoma, the age, sex and the handling that has occurred them, in a series of 684 patients of the National Institute of Enfermedades Neoplásicas (INEN) between the 1 of January from 1974 to the 31 of March of the 2004. MATERIAL AND METHODS: The revision of clinical histories of 840 patients with the diagnosis of colon polyp was made who attended the service of Gastroenterology of the INEN between the 1 of January from 1974 to the 31 of March of 2004 and a card predesigned for each clinical history filled. The study is of observational, analytical type and of cross section. 1162 resecteds polyps evaluated themselves in this period. 156 patients by diagnosis related to cancer and familiar adenomatouspoliposis did not include themselves. The final sample was of 684 patients, in whom it was 1057 polyps. Other endoscopic findings were: internal hemorrhoids (172), colonic diverticulosis (50), anal fissure (4), and nonspecific ulcerative colitis (2). The statistical processing was made with program SPSS 12. For the qualitative variables the method of the Chi-square was used, for the quantitative variables analyzed the average, the rank and the variance. RESULTS: 1057 polyps extirpated, by means of the endoscopy polipectomy were 1016, with colectomy were 32 and with transanal resection without colectomy they 9. Within the histology of the 1057 polyps, 331 was briefed (31.3%) that were hyperplasic, 448 (42.4%) adenomas, 278 (26.3%) others and 35 (8.2%) adenocarcinomas on adenomas. The average age was of 50 years, was no significant difference with sex. The location but frequence of the adenomas was in the left colon (76.6%). Adenocarcinoma (carcinomas on adenomas), was present mainly in polyps villous type, with dysplasia severe and greater to 10 mm. Nevertheless, in smaller polyps of 5mm with dysplasia severe, was a polyp invaded by cancer, that represents the 0,8% of millimetric polyps. The made handling was mainly endoscopic, with 96% of the resected polyps this way, also slogan transanal resection and segmental colonic resection. The colectomy was necessary in 3% of all the made interventions, dysplasia severe or carcinoma was made in adenomatous polyps with, and in greater percentage in greater polyps of 20 mm (53%). The single polipectomy was sufficient in the level of invasion Haggitt 0. In patients with level of invasion Haggitt 1 and 2, the single polipectomy was the election treatment. On the other hand, in polyps with level of invasion Haggitt 3 and 4, the colectomy was the election treatment. One briefed two complications, one of perforation and peritonitis and another one of digestive hemorrhage loss (both: 0.29%), without mortality events. CONCLUSIONS: The Evaluation of colonic polyps in INEN is predominantly by endoscopy. The polyps are more frequent over the 50 years and have preferred location in the left colon. The carcinoma is more probable with severe dysplasia and greater size of the adenoma. All polyps, from the millimetric ones, including the hyperplasic, must be considered marks of neoplasia and extirpated in its totality.

ABSTRACT

INTRODUCTION: Primary Gastric Lymphoma is an uncommon malignancy among gastric malignancies. Histology of the Primary Gastric Lymphoma is varied and the extranodal marginal zone B-cells lymphoma is specially significant on account of its potential remission with antibiotic therapy. OBJECTIVES: Observe the clinical characteristics of patients with Primary Gastric Lymphoma, assess the most relevant endoscopic findings, identify the factors that influence survival and evaluate the effects of therapy. MATERIALS AND METHODS: The study is an observational, analytical, cross evaluation including 169 patients with histological diagnosis of Gastric Lymphoma, treated at the National Institute for Neoplastic Diseases, Lima, Peru, from January 1995 to December 2000. Staging was based on the Ann Arbor system, modified by Musshoff and histology, on the REAL-WHO classification. The statistical analysis included the student-t and the chi-square tests. Survival data were entered using the Kaplan Meier curves and prognosis factors, using the Cox regression test. RESULTS: The sample represents patients from the Peruvian Coast, with a mean age of 55 years old and slight predominance of female patients (54.4%). Signs and symptoms are unspecific. Clinical stage I-II corresponds to 75% of the patients. The endoscopic pattern of multiple ulcerated lesions is characteristic of the Gastric Lymphoma. A total of 71% of the patients with extranodal marginal zone B-cells lymphoma showed total remission of the disease with antibiotic therapy (5/7). The histological type of the Gastric Lymphoma in the 169 patients was as follows: Large, diffuse, B-cells Lymphoma, 137 patients, extranodal marginal zone B-cells lymphoma, 16 patients, peripheral T-cell Lymphoma, 6 patients, anaplastic large T-cell Lymphoma, 3 patients, undetermined Lymphoma, 3 patients, mantle cell Lymphoma, 2 patients, adult T-cell Lymphoma, 1 patient and follicular Lymphoma, 1 patient. Global survival after 36 months was of 61.34%, survival according to the histological type was of 92.31% for extranodal marginal zone B-cells Lymphomas, 62.21% for large, diffuse B-cells Lymphomas and 29.63% for T-cell Lymphomas. Survival after 36 months in patients in clinical stage I-II treated with chemotherapy, was of 82.16%, with surgery, 71.89% and with surgery and chemotherapy, 70.39, with similar results in all three groups (p: 0.6530). The groups classified according to the international index, showed a clear difference between them (p:0.0000). The univariate analysis revealed that Zubrod (p:0.0000) DHL (p:0.0073) disease remission (p:0.0000) stage (p:0.0000) treatment (p:0.0000) and location (p:0.0000) had statistical significance. Multivariate analysis showed that in the Cox regression model, remission (OR:13,342, p:0.0000) and location (OR:2.375, p:0.041) fall within the equation of such function. CONCLUSIONS: The multiple ulcerated lesions are characteristic of the Gastric Lymphoma. Remission of the disease in the extranodal marginal zone B-cells Lymphoma is evidenced with the use of antibiotic therapy (5/7). Chemotherapy in patients with EC I-II achieves survival results similar to those treated with surgery and with a combination of both. Validity of the international index is confirmed and the multivariate analysis proved that remission and location of the disease have statistical significance.

ABSTRACT

El tratamiento endoscópico del cáncer gástrico temprano mediante la mucosectomía ha demostrado ser una modalidad efectiva de terapéutica local, especialmente si el tumor está circunscrito a la mucosa, es menor de 3 cm, carece de componente ulceroso, no presenta invasión linfática y tiene los bordes de sección libres de neoplasia. La mucosectomía también ha demostrado ser útil en la resección de lesiones elevadas gástricas, como los adenomas. Sobre un periódo de dos años (1996-1997), cinco pacientes (3 varones y 3 mujeres), con diagnóstico de cáncer gástrico tempranoen 4 de ellos, y adenoma con displasia moderada (el restante), fueron tratados mediante la mucosectomía, empleando para ello un asa de alambre convencional y utilizando solo corriente de coagulación. Para poder completar el procedimiento, en dos pacientes se resecó la lesión en dos partes. Se logro una remoción completa de todas las lesiones en una sola sesión. No hubo complicaciones. Dos pacientes fueron sometidos a tratamiento quirúrgico radical con linfadenectomía, no apreciándose neoplasia residual, ni metástasis ganglionar en los especímenes resecados. Todos los pacientes permanecen libres de recurrencia durante una media de seguimientos de 16 meses (rango de 9 a 29 meses). El cáncer gástrico temprano y los adenomas gástricos pueden ser adecuadamente tratados mediante la mucosectomía, utilizando para ello un estricto criterio de selección de pacientes.

ABSTRACT

Se revisaron las historias clínicas de 71 pacientes con tumores malignos del intestino delgado (TMID) que fueron operados en el Instituto de Enfermedades Neoplásicas (INEN), Lima-Perú entre 1952 y 1989. treinta y siete (52 por ciento) fueron linfoma; 23 (32 por ciento) adenocarcinoma; 8 (11 por ciento) tumor carcinoide y 3 (5 por ciento) sarcoma. veintidos casos localizados en duodeno; 17 en ileon; 16 en yeyuno y 16 de localización múltiple. La edad promedio 48 años con rango entre 3 y 78. El tiempo de enfermedad 11,8 meses con rango entre 1 y 120 meses. Los síntomas frecuentes: dolor abdominal en 62 (87,3 por ciento); baja de peso 40 (47,8 por ciento), náuseas y vómitos 28 (39, 4 por ciento) y masa abdominal 24 (33,8 por ciento). La resección quirúrgica fue incompleta en 32 (45 por ciento), sólo biopsia en 27 (38,1 por ciento) resección completa en 12 (16,9 por ciento). En la mayoría de casps el tumor comprometió serosa o la sobrepasaba. En 11 casos se encontró metastasis: 6 en hígado 2 en pulmón y 1 en bazo, pared abdominal y ganglio linfático extraabdominal. La sobrevida a 5 y 10 años por todo el grupo fue de 36,8 por ciento y 26,2 por ciento respectivamente. Se concluye que los TMID son poco frecuentes en el INEN y de pronóstico

ABSTRACT

Se revisaron 418 casos de cáncer de estómago diagnosticados histológicamente entre los añs 1952 y 1972, en el Instituto de Enfermedades Neoplásicas. Se estudiaron edad, sexo, y localización anatómica. De acuerdo a la clasificación de Lauren fueron clasificados: tipo intestinal 221/418 casos (52.8 por ciento), tipo difuso 181/418 (43.3 por ciento) y tipo mixto 16/418 casos (3.8 por ciento). El tipo intestinal fue el más frecuente en ambos sexos y se incrementó con la edad, por el contrario el tipo difuso disminuyó con la edad. La edad promedio de cáncer de estómago tipo intestinal fue 61.4 años para el sexo masculino y 61.8 para el sexo femenino y la edad promedio del tipo difuso fue de 57.0 años para varones y 54,0 años para mujeres. La localización distal fue la zona más frecuente de cáncer de estómago en el 78.9 por ciento (330/418), seguido de la localización proximal (11.7 por ciento). El estudio del cáncer de estómago según la clasificación de Lauren, puede representar una forma de estudio de la epidemiología en cáncer gástrico

ABSTRACT

Se realizó un estudio retrospectivo de 157 pacientes portadores de neoplasia maligna germinal de ovario atendidas en el Departamento de Ginecología del INEN (Lima-Perú) durante los períodos enero 1980-diciembre 1993. Estos 157 casos representan el 14.05 por ciento de las NM de ovario de éste periodo. El tipo histológico más frecuente fue el disgerminoma (50.4 por ciento), el tumor del seno endodermal (16.5 por ciento), T.G. mixto (15.9 por ciento), teratoma inmaduro (14.6 por ciento), coriocarcinoma (1.3 por ciento) y cacinoma embrionario (1.3 por ciento). La edad de presentación promedio fue 17.26 semanas y el sítoma principal fue el dolor en 42 por ciento. De los 201 pacientes, 157 (64.4 por ciento) fueron tratados quirurgicamente en nuestra institución (64.4 por ciento), ya sea en forma primaria o re-exploración: 56 pacientes (35.6 por ciento) tuvieron solo cirugía en otra institución. En la re-exploración (50 casos) se encontró sub-estadiaje del orden 30-40 por ciento. El estadio cínico quirúrgico-patológico (101 pacientes) mostró: I (38 pac.), II (4 pac.), III (51 pac.) y IV (8 pac.), 121 pacientes tuvieron un seguimiento global de 31 meses. Analizándose los dos grandes grupos (disgerminoma y no disgerminoma) la sobrevida global de 5 años fue de 81 por ciento con el régimen quimioterápico a base de platino, 42 pacientes tuvieron un tratamiento quimioterápico complementario a base de platino, se realizaron 9 second look y en ninguno se encontró enfermedad con un promedio de seguimiento de 14.5 meses (SEE). Hubieron 8 pacientes (19.1 por ciento) que presentaron resistencia a la Qt (PVB), utilizándose Qt de rescate sin efectividad alguna. Factores pronósticos evaluados: La enfermedad residual (> o < de 2 cm) y el manejo quirúrgico (conservador vs no conservador) no mostraron diferencias significativas. En conclusión estamos ante una neoplasia maligna con mayor incidencia en la segunda década de la vida, quimio-sensible; que gracias a los agentes quimioterápicos actuales nos permiten realizar un manejo conservador con el objeto de mantener la fertilidad de las pacientes. Quedando aún por resolver al 20 por ciento de pacientes quimio-resistentes a los esquemas tradicionales.

ABSTRACT

En este estudio fueron admitidos 31 pacientes evaluables con diagnóstico de Cáncer Gástrico. La edad media fue 71 años (rango 24-82). 22 fueron varones. Ninguno recibió quimioterapia previa. La capacidad funcional fue 0-1 en 26/31 (60.6%). Los síntomas más frecuentes fueron: baja de peso 21/31 (75.1%) y dolor abdominal en 13/31 (40.3%). 10 pacientes fueron catalogados como Borrmann III y 9 Borrmann IV. 21 casos fueron sometidos a cirugía: 12 gastrectomía paliativa y 9 laparotomía exploradora. 23 casos fueron Adenocarcinoma y 8 Carcinoma indiferenciado. Se administró el régimen FEM (5 Fluoruracilo 600 mg/m2/ día 1 y 8, Epidoxorubicina 30 mg/m2/día y Mitomicina 10 mg/m2/día), 10 de 24 pacientes (41.7%) alcanzaron remisión parcial con una sobrevida media de 10.5 meses. 3 pacientes tuvieron una respuesta subjetiva con una sobrevida media de 6 meses. La sobrevida media en el grupo de no respuesta fue 3 meses (rango 2 a 7 meses). La diferencia de sobrevida entre el grupo que respondió y no respuesta fue estadísticamente significativa. La sobrevida en el grupo que recibió tratamiento adyuvante fue 5.7 meses (rango 2 a 16). 1 de 3 pacientes sobrevive sin evidencia de enfermedad al completar el estudio. 23 fallecieron y 5 se perdieron de vista. El efecto secundario más común fue alopecia (74%), náuseas y vómito (60%), y leucopenia menor de 3000 en 54%. No hubo ningún caso de cardiotoxicidad
