    BACKGROUND: In spite its relative rarity, gallbladder adenocarcinoma is a neoplasm who presents an aggressive biologic behavior. The single curative treatment has been radical surgical resection with free margin. Prognostic factors has been studied because are very important to identify long-term survival patients which may benefit of aggressive surgical resection. AIM: To evaluate long-term prognostic predictors from gallbladder cancer. METHODS: The medical records of all patients that presented confirmed histological diagnosis of gallbladder adenocarcinoma operated over a 14 year period were identified and retrospectively reviewed. Uni and multivariate analysis was done. RESULTS: Total sample was 100 patients. Median age was 71 years (34 to 93). There were 17 men and 83 women. Lesion distribution according to TNM stage system was: I (n=22), II (n=59), III (n=6), IV (n=4) and unknown (n=9). Fifty two patients underwent radical resection (R0) while 48 to palliative surgery (R1-R2). Overall major morbidity was 14%, while postoperative surgical mortality rate (30th postoperative day) was 12 %. Five-year survival rate was 28% while median of survival was 10 months. Multivariate analysis identified six prognostic factors: T stage, serum level of CA 19.9, gallbladder perforation, lymphatic embolization, surgical historical cohort (after 2002) and hilar lymphadenectomy. CONCLUSION: Prognostic factors were: T stage, serum level of CA 19.9, gallbladder perforation, lymphatic embolization, surgical historical cohort and hilar lymphadenectomy.RACIONAL: A despeito da sua relativa raridade, o adenocarcinoma de vesícula biliar é neoplasia que apresenta comportamento biológico agressivo. O único tratamento curativo tem sido a ressecção cirúrgica radical com margem livre. Fatores prognósticos têm sido estudados por serem importantes para identificar pacientes que podem se beneficiar de ressecção cirúrgica agressiva. OBJETIVO: Avaliar preditores prognósticos em longo prazo de pacientes com câncer da vesícula biliar. MÉTODOS: Foram identificados e retrospectivamente revisados os prontuários médicos de todos os doentes submetidos a tratamento cirúrgico que apresentavam diagnóstico histológico confirmado de adenocarcinoma de vesícula biliar durante período de 14 anos. Os dados foram submetidos à análise estatística uni e multivariada. RESULTADOS: A amostra total foi de 100 doentes. A mediana de idade foi de 71 anos (34 a 93). Houve 17 mulheres e 83 homens. A distribuição das lesões de acordo com o sistema de estadiamento TNM foi: I (n=22), II (n=59), III (n=6), IV (n=4) e desconhecido (n=9). Cinquenta e dois doentes foram submetidos à ressecção radical (R0) enquanto 48 à cirurgia paliativa (R1-R2). A morbidade global foi de 14% enquanto que a mortalidade pós-operatória (até 30º dia do pós-operatório) foi de 12 %. A taxa de sobrevida em cinco anos foi de 28% enquanto a mediana de sobrevida foi de 10 meses. A análise multivariada identificou seis fatores prognósticos: estádio T, nível sérico de CA 19.9, perfuração da vesícula biliar, embolização linfática, coorte cirúrgico histórico e linfadenectomia hilar. CONCLUSÃO: O tratamento do câncer de vesícula biliar apresenta alta morbimortalidade. Os fatores prognósticos foram: estádio T, nível sérico de CA 19.9, perfuração da vesícula biliar, embolização linfática, coorte cirúrgico histórico e linfadenectomia hilar.HSPE FMO Hospital Francisco Morato de OliveiraUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

    CONTEXT: Gastrointestinal multiple lymphomatous polyposis is a rare type of malignant lymphoma that has aggressive biological behavior, early systemic dissemination and poor prognosis. It is considered to be a manifestation of non-Hodgkin lymphoma and represents the gastrointestinal counterpart of mantle cell nodal lymphoma. OBJECTIVE: A case of gastrointestinal multiple lymphomatous polyposis is presented and the anatomopathological, clinical, diagnostic and treatment aspects of this unusual neoplasia are discussed. CASE REPORT: The patient was a 59-year-old white male with a complaint of asthenia, night sweating, alteration in intestinal habit and weight loss over the preceding two months. The physical examination showed pallid mucosa and a palpable mass in the epigastrium and mesogastrium. Endoscopy of the upper digestive tract showed the presence of gastric and duodenal polyps. An opaque enema showed multiple polypoid lesions, especially in the cecum. A rectal biopsy revealed infiltration of the mucosa and submucosa by diffuse lymphoma consisting of small cleaved cells. Immunohistochemical study showed lymphocytes that expressed the antibody CD20 (L-26) and light-chain kappa (k) immunoglobulin, but not light-chain lambda (l) immunoglobulin. The patient presented a condition of acute intestinal obstruction with the presence of a mesenteric mass formed by agglutinated lymph nodes that surrounded the proximal ileum, thereby obstructing its lumen. He was submitted to a segmental enterectomy and gastrotomy with excisional biopsies of the gastric polypoid lesions. After two cycles of chemotherapy there was a worsening of the general state, with an increase in the dimensions of the abdominal masses and sepsis, accompanied by progressive respiratory insufficiency, leading to death

    Objectives: To perform a prospective study of frequency, extensionand distribution of antral metaplasia in specimens of gallbladderremoved due to symptomatic lithiasis. Methods: A total of 35patients who underwent elective cholecystectomy was studiedfrom April to June 2002. Patients were divided into two groups -one group comprised patients aged ≤ 53 years and the otherincluded those aged over 53 years. From each gallbladder specimen,three fragments collected from the neck, body and fundus andmeasuring 5mm x 15 mm were processed. Antral metaplasia wasdiagnosed by the presence of cuboid cells with small basal nucleiand abundant cytoplasm containing mucous droplets. Results:There were 27 77.1%) females and 8 (22.9%) males; the medianage was 53 years (range: 21-72 years). Antral metaplasia wasdiagnosed in 21 (60%) specimens as small isolated foci (35.3%) ormultiple foci (64.7%). Intestinal metaplasia was foundconcomitantly in 17 (80.9%) cases. Although antral metaplasiawas more frequent in the older age group (61.9% x 28.6%), thesefindings were not significant. Antral metaplasia was most frequentlyfound in the fundus (42.9% of specimens) and equally in the bodyand neck (25.7%). Conclusions: Antral metaplasia was frequent ingallbladders with lithiasis and chronic inflammatory processremoved in elective surgeries. Additional studies with largernumbers of specimens are necessary for better knowledge aboutthe distribution and extension of this condition in our population

    BACKGROUND: There is controversy regarding the optimal therapy for primary non-Hodgkin gastric lymphoma with some authors defending surgical extirpation either alone or in association with radiotherapy and or chemotherapy, especially in relation to the earlier stages of the disease. AIM: To analyze the clinical-pathological features and the results of management approaches for patients with primary early-stage non-Hodgkin's lymphoma of the stomach operated in Surgical Gastroenterology Department, "Hospital do Servidor Público Estadual", São Paulo, SP, Brazil. The literature is reviewed to highlight the aspects of diagnosis, prognostic factors and role of the various treatment regimens. METHOD: Sixteen patients with primary early-stage gastric lymphoma underwent curative surgical treatment. The variables analyzed were age, sex, location, size, type of surgery, number of lesions, depth of invasion, histological type in accordance with Kiel's classification, involvement of lymph nodes, Ann Arbor stage classification modified by Musshoff and Schmidt-Vollmer, histological grade, margins, adjuvant therapy, clinical course and survival. RESULTS: Ten patients (62.5%) underwent subtotal gastrectomy and six (37.5%) underwent total gastrectomy. The majority (9/56.2%) of the lesions were located in the antrum. Single lesions (10/62.5%) were more frequent than multiple lesions (6/37.5%). Thirteen patients (81.2%) were classified as stage IE and three (18.7%) as stage IIE1. Primary gastric lymphoma classified histologically as low or high grade was presented by 10 (62.5%) and 6 (37.5%) patients, respectively. The most frequent histological types were the lymphoplasmocytic cytoid (4/25.0%) and centroblastic (4/25.0%). Ten patients (62.5%) received adjuvant treatment (chemotherapy and/or radiotherapy). Nine patients (56.2%), all in stage IE, reached a survival greater than 5 years and of these eight (50.0.%) had received adjuvant therapy. Two (12.5%) patients with stage IIE1 presented peritoneal relapse and died 3.0 years and 3.5 years after their respective operations. The mean overall survival was 42,5 months. CONCLUSIONS: Among the patients with primary early-stage gastric lymphoma (IE and IIE1), the gastric resection enabled an accurate clinicopathological staging, in addition to obtaining sufficient material for histopathological study and extirpation of the lesion. Furthermore, for patients with stage IE disease, the gastric resection combined with adjuvant therapy was associated with a greater than 5-year survival. Until prospective randomized studies are realized in order to evaluate the real efficacy of the different types of treatment for primary early-stage gastric lymphoma, management approaches should be individually tailored

    CONTEXT AND OBJECTIVE: Gallbladder cancer is usually diagnosed at a late stage and generally results in death. Discovery of predisposing factors for this neoplasia could prevent this outcome. In this study, we assess the presence of one of these factors: intestinal metaplasia in gallbladders with stones and inflammatory processes. DESIGN AND SETTING: Cross-sectional study in Hospital do Servidor Público Estadual de São Paulo. METHOD: The first 80 gallbladders from patients who underwent elective cholecystectomy between April and August 2002, presenting stones and chronic inflammation, were studied. The patients were divided into groups according to their age: CC1, from 15 to 40 years; CC2, from 41 to 60 years; and CC3, from 61 to 85 years. RESULTS: Twenty-one patients (26%) were male, while 59 (74%) were female. In the group CC1, intestinal metaplasia was present in 85.71% of the 21 patients studied; in CC2, in 79.41% of 34 patients; and in CC3, in 56.00% of 25 patients. These differences presented statistical significance (p = 0.04542). CONCLUSION: Intestinal metaplasia is extremely frequent in gallbladders with inflammation and lithiasis, especially in younger patients
