ABSTRACT

ABSTRACT: Lung cancer is one of the main causes of cancer related deaths. Approximately three quarters of these tumors are non-small cell carcinomas. When diagnosed the majority of patients show the disease locally advanced or metastatic. The chemotherapy is the chosen therapy for patients with advanced lung cancer. The majority of published studies with chemotherapy are performed in academic centers under a strict control of research protocols. PURPOSE: The aim of this study is to evaluate the usual management of metastatic NSCLC patients outside of a clinical trial setting in three different oncologic centers in Brazil. METHODS: This is a retrospective study of patients with metastatic non-small cell lung cancer admitted for treatment in three different Cancer Centers in Brazil. 564 patients from Brazilian public heath system and private/health insurance system were considered for the present study. RESULTS: Among 564 patients in this study, 335 (59.4 percent) received chemotherapy. For all patients, 47 different regimens of chemotherapy were identified. The median follow-up time was eight months and the overall median survival of all patient population submitted to chemotherapy was 9.7 months. DISCUSSION: There was a great heterogeneity in the regimens of drugs to treat metastatic NSCLC patients. The overall survival was significantly better for patients treated with first line chemotherapy compared to patients that only received best supportive care. Results of prospective randomized clinical trials should be carefully analyzed before transferred to the daily clinical practice.


INTRODUÇÃO: O câncer de pulmão é uma das principais causas de morte relacionadas ao câncer. Aproximadamente três quartos destes tumores são carcinoma não pequenas células. Ao diagnóstico, a maioria dos pacientes se apresenta com doença avançada localmente ou metastática. A quimioterapia é o tratamento de escolha para pacientes com câncer de pulmão em estadiamento avançado. A maioria dos estudos publicados com quimioterapia é realizada em centros acadêmicos sob controle rígido de protocolos de pesquisa. OBJETIVO: O objetivo deste estudo é avaliar os resultados do tratamento rotineiro de pacientes com carcinoma de pulmão não pequenas células metastático, fora de protocolos de pesquisa clínica em três centros oncológicos brasileiros. MÉTODO: Trata-se de um estudo retrospectivo de pacientes com câncer de pulmão não pequenas células metastático, admitidos para tratamento em três diferentes centros oncológicos no Brasil. Foram avaliados 564 pacientes neste estudo provenientes do sistema de saúde público e privado. RESULTADOS: Dentre os 564 pacientes deste estudo, 335 (59,4 por cento) receberam quimioterapia. Considerando todos os pacientes, foram identificados 47 esquemas diferentes de quimioterapia. O tempo médio de seguimento foi de oito meses e a sobrevida global mediana de todos os pacientes submetidos à quimioterapia foi de 9,7 meses. DISCUSSÃO: Havia uma grande heterogeneidade de esquemas de drogas para o tratamento de pacientes com câncer de pulmão não pequenas células metastático. A sobrevida global foi significativamente melhor para pacientes tratados com quimioterapia de primeira linha comparado com pacientes que receberam somente tratamento de suporte clínico. Resultados de estudos clínicos prospectivos randomizados deverão ser cuidadosamente analisados antes de serem transferidos para a prática clínica diária.

ABSTRACT

Esclerose sistêmica é uma doença rara do tecido conectivo que frequentemente afeta a pele e os pulmões. A associação entre neoplasias e esclerodermia é objeto de controvérsia. A relação entre câncer de mama e esclerose sistêmica é descrita, mas estudos epidemiológicos demonstram uma correlação negativa entre ambas, provavelmente devido ao pequeno número de pacientes. Neste artigo, os autores relatam três casos de câncer de mama e esclerose sistêmica e realizam revisão da literatura.

ABSTRACT

INTRODUCTION: In the postmenopausal period, an average of 25 percent of women will present symptomatic ovarian failure requiring hormonal replacement therapy. Estrogen can relieve vasomotor symptoms. Hormonal replacement therapy is generally not recommended for breast cancer patients due to the potential risk of tumor recurrence. To answer the questions about the safety of hormonal replacement therapy in this subgroup of women, it is necessary to establish the acceptance of treatment. METHODS: Between September 1998 and February 2001, a cohort of 216 breast cancer patients were asked to complete a questionnaire. All patients had completed their treatment and were informed about survival rates after breast cancer and hormonal replacement therapy. RESULTS: Among the 216 patients, 134 (62 percent) would refuse hormonal replacement therapy. A hundred patients were afraid of relapse (74.6 percent). Adjuvant tamoxifen therapy was the only statistically significant variable (70.3 percent versus 29.7 percent p=0.003). Understanding clinical stage (p= 0.045) and type of medical assistance (private versus public , p=0.033) also seemed to influence the decision. Early stage disease (p= 0.22), type of surgical procedure (radical versus conservative, p=0.67), adjuvant chemotherapy (p=0.082) or marital status (p=0.98 ) were not statistically significant in decision making. Several patients submitted to adjuvant chemotherapy (41.6 percent) would accept hormonal replacement therapy under medical supervision, as did most of advanced clinical stage patients (58.3 percent; p=0.022). CONCLUSION: There is a high level of rejection for hormonal replacement therapy among breast cancer patients when current data on tumor cure rates, and potential risks of estrogen use is available. Adverse effects of tamoxifen in the adjuvant setting may be the reason for refusal of hormonal replacement therapy

ABSTRACT

Stage IV non-small cell lung cancer is a fatal disease, with a median survival of 14 months. Systemic chemotherapy is the most common approach. However the impact in overall survival and quality of life still a controversy. OBJECTIVES: To determine differences in overall survival and quality of life among patients with stage IV non-small cell lung cancer non-metastatic to the brain treated with best supportive care versus systemic chemotherapy. PATIENTS: From February 1990 through December 1995, 78 eligible patients were admitted with the diagnosis of stage IV non-small cell lung cancer . Patients were divided in 2 groups: Group A (n=31 -- treated with best supportive care ), and Group B (n=47 -- treated with systemic chemotherapy). RESULTS: The median survival time was 23 weeks (range 5 -- 153 weeks) in Group A and 55 weeks (range 7.4 -- 213 weeks) in Group B (p=0.0018). In both groups, the incidence of admission for IV antibiotics and need of blood transfusions were similar. Patients receiving systemic chemotherapy were also stratified into those receiving mytomycin, vinblastin, and cisplatinum, n=25 and those receiving other combination regimens (platinum derivatives associated with other drugs, n=22). Patients receiving mytomycin, vinblastin, and cisplatinum, n=25 had a higher incidence of febrile neutropenia and had their cycles delayed for longer periods of time than the other group. These patients also had a shorter median survival time (51 versus 66 weeks, p=0.005). CONCLUSION: In patients with stage IV non-small cell lung cancer, non-metastatic to the brain, chemotherapy significantly increases survival compared with best supportive care

ABSTRACT

A fotemustina é uma nitrosuréia de terceira geração, ativa em melanoma maligno disseminado e especialmente contra metástases cerebrais, pela habilidade em atravessar a barreira hematoencefálica. A sua eficácia tem sido amplamente demonstrada em estudos de fase II, como monoterapia ou terapia combinada com dacarbazina. Nos estudos com monoterapia, a taxa de resposta varia de 16 por cento a 47 por cento, com maior taxa nos sítios não-viscerais e cerebral, respectivamente, bem como em pacientes previamente não tratados com quimioterapia. A principal toxidade da droga é hematológica. Em terapia combinada, a associação com dacarbazina é considerada vantajosa, devido à menor tolerabilidade e menor toxicidade hematológica. A combinação seqüencial com objetivo de sinergismo na depleção da alquiltransferase, diminuindo assim o mecanismo de resistência celular, tem mostrado eficácia clínica aceitável, principalmente quando a fotemustina é administrada 24 horas após dacarbazina.

ABSTRACT

O objetivo primário do estudo foi verificar a utilizaçäo dos marcadores tumorais na prática clínica diária. Utilizando a lista de endereços da Sociedade Brasileira de Oncologia Clínica, 330 questionários foram enviados, direcionados ao uso dos marcadores tumorais. Trinta porcento dos questionários foram retornados . As indicaçöes para rastreamento populacional, seguimento de doença tratada com intençäo curativa e tratamento de doença metastática foram heterogêneas. A inconstância das respostas fortalece a necessidade de uma padronizaçäo nacional no uso de marcadores tumorais.

ABSTRACT

Consideradas no passado como incuráveis, muitas neoplasias malignas apresentam hoje taxas de cura cada vez maiores. Dentre as hemopatias malignas, a possibilidade de troca medular proporciona nÝo apenas remissÝo, mas cura. O transplante de medula óssea, autólogo ou alogênico, oferece esta possibilidade a portadores de tumores sólidos ou hematológicos. Neste artigo, os autores fazem uma revisÝo sobre os conceitos básicos, histórico, indicaçSes e complicaçSes deste procedimento.
