In spite of the many available protocols, the use of chemotherapy for the management of canine mast cell tumours (MCT) remains empirical, and there is lack of criteria for the choice of protocol and definition of patients who may benefit from treatment. The objective of this study was to evaluate the outcome of dogs with MCT after adjuvant chemotherapy according to the risk of recurrence or metastasis proposed on the literature. This prospective study included 89 followed up dogs with prognosis assesment including clinical, histological, immunohistochemical and genetic features of canine MCT. Patients were grouped according to risk of recurrence and metastasis and recommended treatment with lomustine followed by chlorambucil if considered at high-risk, or vinblastine followed by chlorambucil if a patient was at intermediate risk. Outcome was defined by disease-free interval (DFI) and overall survival (OS) estimated by Kaplan-Meier curve. Adjuvant lomustine was useful for control of canine MCT of high-risk of recurrence or metastasis, but only when sequentially associated to chlorambucil with a DFI of 686 days and not reached OS. There was no difference in outcome in the intermediate-risk group despite choosen treatment. Patients at intermediate-to-low risk may not require adjuvant treatments, even in the absence of free surgical margins.(AU)

Apesar dos inúmeros protocolos disponíveis, o uso da quimioterapia permanece empírico para o mastocitoma canino e faltam critérios para escolha do protocolo e da definição dos pacientes que poderiam se beneficiar do tratamento. O objetivo deste estudo foi avaliar o resultado de cães com mastocitoma após a quimioterapia adjuvante, de acordo com o risco de recorrência ou metástase proposto na literatura. Este estudo prospectivo incluiu 89 cães com acompanhamento clínico e avaliação prognóstica, incluindo características clínicas, histológicas, imuno-histoquímicas e genéticas dos mastocitomas. Os pacientes foram agrupados segundo o risco de recorrência ou metástase, sendo recomendado tratamento com lomustina seguida de clorambucila, se considerados sob alto risco, ou vimblastina seguida de clorambucila, se estivessem sob risco intermediário. O resultado final foi definido pelo intervalo livre de doença (ILD) e pela sobrevida global (SG), estimados pela curva de Kaplan-Meier. Na adjuvância, a lomustina foi útil no controle do mastocitoma canino de alto risco, mas apenas quando associada ao clorambucila, com um ILD de 686 dias, sem atingir a mediana para SG. Não houve diferença no grupo de risco intermediário, independentemente do tratamento escolhido. Pacientes de risco intermediário podem não necessitar de tratamentos adjuvantes, mesmo na ausência de margens cirúrgicas livres.(AU)

O linfoma é uma neoplasia originária do sistema linfático, a partir de células linfocitárias. A sintomatologia mais comum é febre, tosse, sudorese noturna, perda de peso, fraqueza e linfoadenopatia indolor. A etiologia ainda permanece desconhecida, tendo sido relacionada ao vírus Epstein-Barr. O diagnóstico se baseia na visualização das células de Reed-Sternberg. O esquema adriamicina, bleomicina, vinblastina e dacarbazina (ABVD) ainda é o tratamento preconizado, associado ou não à radioterapia. Relatamos um caso de linfoma de Hodgkin de apresentação atípica, cujo diagnóstico só foi possível por esplenectomia.(AU)

The lymphoma is a cancer of the lymphatic system originating from lymphocyte cells. The most common symptoms are fever, cough, night sweats, weight loss, weakness, and painless lymphadenopathy. The etiology remains unknown, having been related to the Epstein Barr virus. The diagnosis is based on visualization of Reed Sternberg cells. The adriamycin, bleomicin, vinblastine and dacarbazine (ABVD) regimen is still the preferred treatment, with or without radiation therapy. We report a case of Hodgkin's lymphoma of atypical presentation, the diagnosis of which was only possible through splenectomy.(AU)

Background: Recent trials show that > 90% of patients with early stage Hodgkin`s Lymphoma (ESHL) can be cured, especially when using the ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapeutic (CT) protocol. The use of radiotherapy (RT) is variable and can be selected according to the presence of specific risk factors, including PET-CT, as recently reported. Aim: To report the experience in the treatment of ESHL. Material and Methods: Retrospective and descriptive analysis of patients with ESHL treated at the Red de Salud UC-Christus between 2011-2015. Results: Twenty-two patients were treated. In 73%, the tumor was of nodular sclerosis histologic type. Most patients (95%) were in stage II, and 78% had a favorable prognosis according to the Deutsche Hodgkin Studiengruppe (GHSG) criteria. All patients were stratified using PET-CT and treated using the ABVD CT protocol, for 4-6 cycles. Only 5 patients received RT. There was no change of conduct after interim-PET-CT results. Ninety one percent of patients achieved complete response and there were two cases of refractory disease. Both cases underwent hematopoietic stem cell transplantation. After 17 months of median follow-up, 91% of patients are relapse-free, and only one patient died (5%). Conclusions: ABVD offers excellent results for ESHL patients. The benefit of PET-CT should be evaluated with prospective protocols, aiming to select patients needing RT or to reduce the number of CT cycles.

No Brasil, a hipertensão e o diabetes mellitus tipo 2 são responsáveis por 60% dos casos de doença renal crônica terminal em terapia renal substitutiva. Estudos americanos identificaram agregação familiar da doença renal crônica, predominante em afrodescendentes. Um único estudo brasileiro observou agregação familiar entre portadores de doença renal crônica quando comparados a indivíduos internados com função renal normal. O objetivo deste artigo é avaliar se existe agregação familiar da doença renal crônica em familiares de indivíduos em terapia renal substitutiva causada por hipertensão e/ou diabetes mellitus. Estudo caso-controle tendo como casos 336 pacientes em terapia renal substitutiva portadores de diabetes mellitus ou hipertensão há pelo menos 5 anos e controles amostra pareada de indivíduos com hipertensão ou diabetes mellitus e função renal normal (n = 389). Os indivíduos em terapia renal substitutiva (casos) apresentaram razão de chance de 2,35 (IC95% 1,42-3,89; p < 0,001) versus controles de terem familiares com doença renal crônica terminal, independente da raça ou doença de base. Existe agregação familiar da doença renal crônica na amostra estudada e esta predisposição independe da raça e da doença de base (hipertensão ou diabetes mellitus).

In Brazil hypertension and type 2 diabetes mellitus are responsible for 60% of cases of end-stage renal disease in renal replacement therapy. In the United States studies have identified family clustering of chronic kidney disease, predominantly in African-Americans. A single Brazilian study observed family clustering among patients with chronic kidney disease when compared with hospitalized patients with normal renal function. This article aims to assess whether there is family clustering of chronic kidney disease in relatives of individuals in renal replacement therapy caused by hypertension and/or diabetes mellitus. A case-control study with 336 patients in renal replacement therapy with diabetes mellitus or hypertension for at least 5 years (cases) and a control matched sample group of individuals with hypertension or diabetes mellitus and normal renal function (n = 389). Individuals in renal replacement therapy (cases) had a ratio of 2.35 (95% CI 1.42-3.89, p < 0.001) versus the control group in having relatives with chronic renal disease, irrespective of race or causative illness. There is family clustering of chronic kidney disease in the sample studied, and this predisposition is irrespective of race and underlying disease (hypertension or diabetes mellitus).

Objective Breast cancer (BC) and metastatic breast cancer (MBC) are significant causes of deaths amongst women worldwide, including developing countries. The cost of treatment in the latter is even more of an issue than in higher income countries. ErbB2 overexpression is a marker of poor prognosis and the goal for targeted therapy. This study was aimed at evaluating the cost-effectiveness in Colombia of ErbB2+ MBC treatment after progression on trastuzumab. Methods A decision analytic model was constructed for evaluating such treatment in a hypothetical cohort of ErbB2+MBC patients who progressed after a first scheme involving trastuzumab. The alternatives compared were lapatinib+capecitabine (L+C), and trastuzumab+a chemotherapy agent (capecitabine, vinorelbine or a taxane). Markov models were used for calculating progression-free time and the associated costs. Effectiveness estimators for such therapy were identified from primary studies; all direct medical costs based on national fees-guidelines were included. Sensitivity was analyzed and acceptability curves estimated. A 3 % discount rate and third-payer perspective were used within a 5-year horizon. Results L+C dominated its comparators. Its cost-effectiveness ratio was COP $49,725,045 per progression-free year. The factors most influencing the results were the alternatives' hazard ratios and the cost of trastuzumab. Conclusion Lapatinib was cost-effective compared to its alternatives for treating MBC after progression on trastuzumab using a Colombian decision analytic model.

Objetivo El cáncer de seno (CS) y cáncer de seno metastásico (CSM) son importantes causas de muerte entre las mujeres a nivel mundial y en países en vía de desarrollo. En estos últimos los costos de los tratamientos son aún más preocupantes que en países de alto ingreso. La sobreexpresión de ErbB2 es marcador de pobre pronóstico y objetivo de terapias dirigidas. Se evaluó la costo-efectividad de los tratamientos de CSM ErbB2+ en progresión post-trastuzumab en Colombia. Métodos Se desarrolló un modelo analístico de decisiones para evaluar los tratamientos en una cohorte hipotética de CSM ErbB2+ que progresaron después de un primer esquema con trastuzumab. Las alternativas comparadas fueron: lapatinib+capecitabina (L+C), y trastuzumab más un agente quimioterápico (capecitabina, vinorelbinao un taxano). Se usaron modelos de Markov para calcular el tiempo libre de progresión y los costos asociados. Estimaciones de efectividad fueron identificadas de estudios primarios. Se incluyeron todos los costos médicos directos basados en los manuales tarifarios nacionales. Se realizaron análisis de sensibilidad y curvas de aceptabilidad. Se descontaron costos y resultados a una tasa anual de 3 %, la perspectiva de análisis fue del tercer pagador y el horizonte de 5 años. Resultados L+C domina a sus comparadores con un razón de costo-efectividad de COP $49 725 045 por año libre de progresión. Los factores que más influencian los resultados son los hazard ratios de las alternativas y el costo de trastuzumab. Conclusión Lapatinib es costo-efectivo comparado con sus alternativas para el tratamiento del CSM después de la progresión con trastuzumab en el escenario colombiano.

INTRODUÇÃO: A significância prognóstica do marcador imunológico CD 20 no linfoma de Hodgkin clássico (LHc) ainda é incerta, particularmente no que se refere à refratariedade ao tratamento inicial. OBJETIVOS: Avaliar a influência da positividade do marcador CD 20 na refratariedade do LHc ao tratamento poliquimioterápico inicial, com o esquema doxorubicina 25 mg/m², bleomicina 10 mg/m², vinblastina 6 mg/m² e dacarbazina 375 mg/m² (ABVD), no Ceará, Brasil. MATERIAL E MÉTODOS: Estudo analítico incluindo 97 pacientes com diagnóstico de LHc firmado entre janeiro de 2000 e dezembro de 2004. A análise foi realizada avaliando variáveis demográficas, clínicas e laboratoriais. RESULTADOS: Foi evidenciada uma positividade do CD 20 em 38,1 por cento dos pacientes. Na análise bivariada, CD 20 positivo (razão de chance [RC] = 4,02; intervalo de confiança [IC] = 1,09 - 8,54; p = 0,02), a presença de sintomas B (RC = 4,02; IC = 1,18-17,51; p = 0,01) e a elevação da desidrogenase lática (mediana não-refratários 248,5 [200,5 - 389,5]; mediana refratários 356 [208,5 - 545]; p = 0,03) apresentaram relação de pior prognóstico quanto à refratariedade. Na regressão logística, o CD 20 positivo (RC ajustada = 3,6; IC = 0,99 - 13,09; p = 0,05) e a presença de sintomas B (RC ajustada = 5,41; IC = 1,16 - 25,34; p = 0,03) continuaram apresentando pior prognóstico. DISCUSSÃO: Esses dados coincidem com a literatura, em que a positividade do marcador CD 20 está relacionada com pior resposta ao tratamento com ABVD. CONCLUSÃO: Os nossos dados indicam que o tratamento com ABVD não é completamente adequado para a abordagem terapêutica inicial deste subgrupo de pacientes e novas pesquisas precisam ser realizadas no sentido de aperfeiçoar o tratamento destes pacientes.

INTRODUCTION: The prognostic value of CD20 antigen expression in classical Hodgkin lymphoma (cHL) is uncertain, particularly regarding the refractoriness to first-line treatment. OBJECTIVES: To assess the influence of CD20 positiveness on the refractoriness of cHL to first-line chemotherapy with ABVD protocol in Ceará State, Brazil. MATERIAL AND METHODS: Analytical study including 97 patients diagnosed with cHL between January/2000 and December/2004. The analysis was performed evaluating demographic, clinical and laboratory variables. RESULTS: CD20 antigen expression was positive in 38.1 percent of the patients. In the bivariate analysis, CD20 antigen expression (OR = 4.02; CI = 1.09 - 8.54; p = 0.02), the presence of B-symptoms (OR = 4.02; CI = 1.18-17.51; p = 0.01) and an elevated lactate dehydrogenase level (median not refractory 248.5 [200.5 - 389.5]; median refractory 356 [208.5-545]; p = 0.03) showed worse prognosis as to refractoriness. In the logistic regression analysis, the presence of CD 20 (OR = 3.6; CI = 0.99-13.09; p = 0.05) and B-symptoms (OR = 5.41; CI = 1.16-25.34; p = 0.03) continued to show worse prognosis. DISCUSSION: These findings coincide with literature data indicating that CD 20 antigen expression is associated with low response to treatment with ABVD. CONCLUSION: Our data show that the treatment with ABVD is not totally appropriate for the initial therapeutic approach in this subgroup of patients and that further studies are required to optimize their treatment.

Background: Hodgkin lymphoma is a highly curable disease. Aim: To evaluate the clinical characteristics and the treatment results of Hodgkin lymphoma patients of the National Cancer Program in Chile. Patients and methods: Prospective assessment of 682 patients treated in 18 adult cancer centers. Progression free survival (PFS) and overall survival (OS) were calculated. Median follow up was 127, 95, 87, 72 and 50 months for C-MOPP, radiotherapy (RT), C-MOPP/ABV, NOVP and ABVD, respectively. Results: Median age was 37 years (15-84). Nodular sclerosis and mixed cellularity were equally expressed. Advanced stages (III & IV) were present at diagnosis in 61 percent of cases. Age over 40 was an adverse prognostic factor (p <0.001). The rate of PFS at 5 and 10 years for early stages was 73 percent and 66 percent with RT, 80 percent and 74 percent with C-MOPP+RT, 73 percent and 71 percent with C-MOPP/ABV, 59 percent and 59 percent with NOVP+RT, and 81 percent with ABVD+RT, at 5 years, being significantly lower for NOVP (p =0.02). The rate of OS at 5 and 10 years for advanced stages was 82 percent and 70 percent with RT, 82 percent and 76 percent with C-MOPP+RT, 82 percent and 80 percent with C-MOPP/ABV, 68 percent and 60 percent with NOVP, and 85 percent with ABVD at 5 years, also significantly lower for NOVP (p =0.04). For advanced stages, the rate of PFS at 5 and 10 years was 49 percent and 43 percent with C-MOPP, 69 percent and 62 percent with C-MOPP/ABVD or C-MOPP/ABV, and 71 percent at 5 years with ABVD, significantly lower for C-MOPP (p =0.01). The rate of OS at 5 and 10 years was 52 percent and 46 percent with C-MOPP, 70 percent and 63 percent with C-MOPP/ABVD or C-MOPP/ABV and 76 percent with ABVD at 5 years, significantly lower for C-MOPP (p =0.0002). Conclusions: Age over 40 years was an adverse prognostic factor. C-MOPP/ABVD, C-MOPP/ABV and ABVD had comparable results and reached a high tumor control and overall survival in both early...

A 17 year-old female with stage IIIc endodermal sinus tumor of the ovary developed transient cortical blindness and severe hypertension after 5 cycles of PVB regimen consisting of cisplatin, vinblastine and bleomycin. Clinical and radiological findings were compatible with Posterior LeukoEncephalopathy (PLE). Her visual acuity and blood pressure completely recovered within a few days after supportive treatment with antihypertensive drug. This condition is unpredictable but it can be reversible without long term sequelae. Most reports suggested that this rare toxicity was from cisplatin therapy. However, the exact pathophysiogenesis of this condition was not known precisely. Prompt reduction in blood pressure and withdrawal of immunosuppressive agents might lead to rapid reversal of this syndrome and prevent permanent brain damage.

Intracraneal manifestations of Hodgkin's Disease (HD) are extremely rare, with an estimated incidence rate of approximately 0.5%. They can be classified as: 1) treatment-related leucoencephalopathy, 2) central nervous system infections, 3) paraneoplasic syndromes and 4) intracraneal lymphomas, which could be sub-classified into intraparenchymal or intradural masses. We describe a case of a 40 year-old male with mixed cellularity type HD who developed neurological manifestations as relapsed disease. Magnetic resonance imaging suggested leptomeningeal metastases and atypical cells were found in cerebrospinal fluid. The patient died from progressive disease refractory to third line chemotherapy. There are less than 50 similar cases reported in the literature. We review the clinical features and differential diagnosis of leptomeningeal metastases in Hodgkin's disease.

Advanced Hodgkin's disease is usually treated with six or more cycles of combination chemotherapy. Spontaneous regression of the cancer is very rarely reported in patients with Hodgkin's disease. We present an unusual case of a patient with Hodgkin's disease who experienced complete remission with a single cycle of chemotherapy, followed by pneumonia. The case was a 36-year-old man diagnosed with stage IVB mixed cellularity Hodgkin's disease in November 2000. After treatment with one cycle of COPP-ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine) chemotherapy without bleomycin, the patient developed interstitial pneumonia and was cared in the intensive care unit (ICU) for two months. Follow-up chest computerized tomography (CT), performed during the course of ICU care, revealed markedly improved mediastinal lymphomatous lesions. Furthermore, follow-up whole body CT and 18-fluorodeoxyglucose positron emission tomography showed complete disappearance of the lymphomatous lesions. Four years later, the patient is well and without relapse. This report is followed by a short review of the literature on spontaneous regression of Hodgkin's disease. To the best of our knowledge, this is the first case report of spontaneous remission of Hodgkin's disease in Korea.

OBJECTIVE: To determine whether pretreatment with amifostine would reduce the toxicity of cisplatin with no reduction in antitumor efficacy in patients with advanced non-small lung cancer PATIENTS AND METHOD: Patients with locally advanced or metastatic non-small cell lung cancer, aged less than 75 years, with an Eastern Cooperative Oncology Group (ECOG) performance status 0-2 were enrolled in the study. Amifostine was administered at a dose of 740 mg/m2 before chemotherapy. Then cisplatin at 100 mg/m2 was administered on day 1 and vinblastine 5 mg/m2 given on days 1, 8 and 15 in a 28 day cycle. RESULTS: Forty one patients were enrolled Baseline characteristics included; a median age of 58 years (range, 28-72); 23 males and 18 females; performance status of 0 (1 patient), 1 (38 patients) and 2 (2 patients); stage IIIa (1 patient), stage IIIb (10 patients) and stage IV (30 patients). The predominant histology was adenocarcinoma (60.97%). A median of 4 cycles (range, 1-6) were administered Thirty six cases out of forty one patients were assessable for response. The response rate was 38%. All those responding gave partial response. The median survival time was 33 weeks. One and two years survival were 23.9% and 9% respectively. Grade 3/4 toxicity was primarily hematologic. Grade 3/4 leukopenia occurred in 12.4%. Grade 3/4 thrombocytopenia occurred in 1.2%. Anemia grade 3/4 occurred in 7.5%. The observed grade 3/4 nonhematological toxicities were hypertension, hypocalcemia, nausea and vomiting and sensory neuropathy. Other toxicities were grade 2 or below. CONCLUSION: This study demonstrated that amifostine has the potential to be a broad spectrum cytoprotectant of normal tissues from toxicity caused by chemotherapy and no effect on therapeutic outcome in lung cancer patients.

BACKGROUND: This prospective phase II trial was performed to determine the efficacy and toxicity of mitomycin C, vinorelbine and cisplatin combination chemotherapy for patients with previously untreated stage IIIB or IV non-small cell lung cancer (NSCLC). METHODS: Between January 1999 and April 2001, 30 patients with chemotherapy- naive stage IIIB or IV NSCLC were entered into this study. Mitomycin C at a dose of 7 mg/m2, vinorelbine at a dose of 25 mg/m2 and cisplatin at a dose of 75 mg/m2 on day 1 and vinorelbine at a dose of 25 mg/m2 on day 8 were administered. This regimen was repeated every 4 weeks. RESULTS: 29 patients out of 30 patients were assessable. Among the assessable patients, 15 (51.7%) patients had a partial response. The median duration of response and survival was 22 weeks and 39 weeks, respectively. Grade 3 or 4 leukopenia and thrombocytopenia were observed in 28.3% and 4.7% of all the cycles, respectively. Nausea and vomiting of grade 3 occurred only in 2.4% of all the cycles. CONCLUSION: The regimen of mitomycin C, vinorelbine and cisplatin for non-small cell lung cancer is active against advanced NSCLC with tolerable toxicities.

40 pacientes con cáncer de pulmón no células pequeñas avanzado no tratados previamente fueron incluídos en un estudio en fase II con vinorelbine 20 mg/m2 días 1 y 8, etopósido 60 mg/m2 días 1-3 y cisplatino 75 mg/m2 día 1 c/28 días por 6 ciclos. Hubo 31 hombres y 9 mujeres, siendo de 54 años el promedio de edad con "performance status" grado 0-2. Todos fueron evaluables para toxicidad y 31 lo fueron para respuesta. 10 pacientes se encontraban en estadio IIIb y 21 en estudio IV. Se obtuvieron 42 por ciento de respuestas objetivas y una sobrevida global de 9 meses, lo que justifica estudios posteriores.

De junio de 1986 a junio de 1989, 47 pacientes con diagnóstico de seminoma testicular fueron tratados en los Departamentos de Oncología Médica y Radioterapia del Hospital de Oncología del Centro Médico Nacional. En la etapificación post orquiectomía radical inguinal se encontró que el 59.5 por ciento de los casos fueron etapas II, el 25.5 por ciento recurrencias de etapas IA, mantenidos en vigilancia después de la cirugía y el resto correspondió a etapas IA (6.3 por ciento), III y IV (8.5 por ciento). La enfermedad voluminosa a nivel retroperitoneal fue el problema médico dominante en el 89 por ciento de los casos en etapa II y en el 66.6 por ciento de los casos recurrentes. El tratamiento inicial en todos los casos fue con quimioterapia a base de esquemas con Cis-platino (VBP o EP), el número de cilos varió de 2 a 6. posterior a la quimioterapia 27 pacientes recibieron manejo con radioterapia, 10 de ellos de manera electiva tras una respuesta completa con la quimioterapia, 12 recibieron radioterapia después de respuesta parcial a la quimioterapia con residual tumoral retroperitoneal, y el resto de los pacientes recibieron tratamiento paliativo además de quimioterapia se segunda línea por falla o recurrencia a quimioterapia. La sobrevida actuarial a 5 años fue de 46 por ciento con una media de seguimiento de 42 meses (rango 24 a 98 meses). Comparativamente la sobrevida fue estadísticamente significativa (p= 0.03) mayor para el grupo de manejo combinado, 62 por ciento a 5 años, que para el grupo tratado sólo con quimioterapia, 20 por ciento a 5 años

Ten patients of the advanced malignant germ cell tumours of the ovary were treated by cisplatin based combination chemotherapy after initial conservation surgery. Eight patients completed course containing cisplatinum, vinblastine and bleomycin. Five patients (62.5%) achieved CR while 2 (25%) attained PR. One patient died due to tumour lysis and respiratory infection. Rest two patients did not turn up in follow up. Long term follow up indicates above regimen to be highly effective. However poor performance status, advanced stage of disease and post operative gross residual disease were poor prognostic factors in our patients.

Thirty-four patients with non small cell lung cancer were treated with a combination of vinblastin and mitomycin-C. Major radiological response was observed in 61.5% of cases. Median survival of the treated patients was 6 months and it was 7 months for those showing a major response. Fourteen of the 21 responders survived for 6 months or more, and 4 survived for more than a year. Leucopenia was a common side effect, and it did not produce any major infective complication. We did not find any advantage of this regimen over other less expensive drugs used in our earlier trials.
