Comparative study of prognostic factors among longer and shorter survival patients with bronchogenic carcinoma

Despite the improvements seen in the treatment of lung cancer, little has improved in the survival of these patients, and a great importance is attributed to the factors that have a role to play in such survival. Purpose: To check for possible prognostic factor differences in two populations of lung cancer patients, one of them with short survival (less than six months), and the other with longer survival (more than 24 months). Methods: From 1997 to 1999, 52 patients with histopathologic diagnosis of homogenous carcinoma were studied, and demographics, clinical parameters, smoking pattern, Karnofsky's index, disease staging, and laboratory dosing of lactic dehydrogenase, alkaline phosphatase, carcinoembryonic antigen, and calcium data were surveyed. Results: 29 patients had less than six month survival, and 23 had more than 24 month survival. The three most important factors for short survival were the low initial Karnofsky's index, loss of appetite, and high serum LDH levels. Conclusion: The three prognosis components are: current physical status, prior physical status, and current status of the disease.Apesar dos avanços no tratamento, há pouca melhora na sobrevida dos pacientes com câncer do pulmão. Atualmente, é importante o conhecimento dos fatores que intervêm na sobrevida. Objetivos: Verificar possíveis diferenças de fatores prognósticos em duas populações de pacientes com câncer de pulmão, uma com pequena sobrevida (menos de seis meses) e outra com maior sobrevida (acima de 24 meses). Métodos: De 1997 a 1999 foram estudados 52 pacientes com diagnóstico histopatológico de carcinoma homogênico, sendo colhidos dados demográficos, clínicos, paramétricos, hábitos tabágicos, índice de Karnofsky, estadiamento da doença e dosagem laboratorial de desidrogenase lática, fosfatase alcalina, antígeno carcinoembrionário e cálcio. Resultados: 29 pacientes tiveram sobrevida menor do que seis meses e 23, superior a 24 meses. Os três fatores mais importantes que influenciaram o tempo curto de sobrevida foram baixo índice de Karnofsky inicial, redução do apetite e alto nível sérico de DHL. Conclusão: Os três componentes do prognóstico são o estado físico atual, o estado físico prévio e o estado atual da doença.Universidade Federal de São Paulo (UNIFESP) Disciplina de PneumologiaUNIFESP, Disciplina de PneumologiaSciEL

Reproducibility of the Brazilian Portuguese version of the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire used in conjunction with its lung cancer-specific module

OBJECTIVE: The assessment of the quality of life in patients with lung cancer has become one of the main goals in current clinical trials. To assess the quality of life of these patients, the most widely used instrument is the 30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) in conjunction with its supplemental 13-item lung cancer-specific module (QLQ-LC13). The objective of this study was to assess the reproducibility of the Brazilian Portuguese version of these questionnaires. METHODS: A prospective study involving 30 stable outpatients with lung cancer who completed the instruments on the first day of the study and two weeks later. RESULTS: The test-retest reproducibility using the intraclass correlation coefficient for the EORTC QLQ-C30 and the QLQ-LC13 ranged from 0.64 to 1.00 and from 0.64 to 0.95, respectively. No correlations were found between the domains of the instruments and clinical parameters. CONCLUSIONS: Our findings show that these instruments were reproducible in this sample of patients with lung cancer in Brazil.OBJETIVO: A avaliação da qualidade de vida em pacientes com câncer de pulmão tem se tornado um dos principais objetivos em ensaios clínicos atuais. Para avaliar a qualidade de vida desses pacientes, o instrumento mais utilizado é o 36-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) em conjunto com seu módulo específico para câncer de pulmão com 13 itens (QLQ-LC13). O objetivo deste estudo foi avaliar a reprodutibilidade da versão em português do Brasil desses questionários. MÉTODOS: Estudo prospectivo com 30 pacientes ambulatoriais estáveis com câncer de pulmão, os quais completaram os instrumentos no primeiro dia do estudo e duas semanas depois. RESULTADOS: A reprodutibilidade teste-reteste através do coeficiente de correlação intraclasse para o EORTC QLQ-C30 e o QLQ-LC13 variou de 0,64 a 1,00 e de 0,64 a 0,95, respectivamente. Não houve correlações entre os domínios dos instrumentos e os parâmetros clínicos. CONCLUSÕES: Estes achados demonstram a reprodutibilidade dos instrumentos utilizados nesta amostra de pacientes com câncer de pulmão no Brasil.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Ambulatório de OncopneumologiaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MedicinaUNIFESP, EPM, Ambulatório de OncopneumologiaUNIFESP, EPM, Depto. de MedicinaSciEL

Non-small cell lung cancer in never smokers: a clinical entity to be identified

OBJECTIVES: It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among neversmokers with non-small cell lung cancer. METHODS: All consecutive non-small cell lung cancer patients diagnosed (n = 285) between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current) were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable), gender (female vs. male), smoking status (never- vs. ever-smoker), the Karnofsky Performance Status Scale (continuous variable), histological type (adenocarcinoma vs. non-adenocarcinoma), AJCC staging (early vs. advanced staging), and treatment (chemotherapy and/or radiotherapy vs. the best treatment support). RESULTS: Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32%) and have adenocarcinoma (70% vs. 51%). Overall median survival was 15.7 months (95% CI: 13.2 to 18.2). The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. CONCLUSIONS: Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type

Assessment of the quality of life of patients with lung cancer using the Medical Outcomes Study 36-item Short-Form Health Survey

OBJECTIVE: To assess the quality of life of patients with lung cancer and to compare it with that of individuals without cancer. METHODS: The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) was administered to 57 patients diagnosed with lung cancer, treated at the Lung Cancer Outpatient Clinic of the Hospital São Paulo, and to a control group of 57 individuals recruited from the Extra Penha workout group. The Mann-Whitney test was used to compare the groups, domain by domain. The first model of logistic regression was adjusted for male gender, nonsurgical treatment, Karnofsky performance status and smoking, which were included as predictors. The second model was adjusted for each SF-36 domain in order to identify increases in the proportions of patients in stage IIIB or IV. RESULTS: The lung cancer group and the control group presented the following mean scores, respectively, for the SF-36 domains: role limitations due to physical health problems, 29.39 ± 36.94 and 82.89 ± 28.80; role limitations due to emotional problems, 42.78 ± 44.78 and 86.55 ± 28.77; physical function, 56.49 ± 28.39 and 89.00 ± 13.80; vitality, 61.61 ± 23.82 and 79.12 ± 17.68; bodily pain, 62.72 ± 28.72 and 81.54 ± 19.07; general health, 62.51 ± 25.57 and 84.47 ± 13.47; emotional well-being, 68.28 ± 23.46 and 82.63 ± 17.44; and social functioning, 72.87 ± 29.20 and 91.67 ± 17.44. The logistic regression model showed that role limitations due to physical health problems, physical function and emotional well-being were predictors of stages IIIB and IV. CONCLUSIONS: The patients with lung cancer had a poorer quality of life, especially regarding physical aspects, than did the control subjects.OBJETIVO: Avaliar a qualidade de vida de pacientes com câncer de pulmão e compará-la com a qualidade de vida de indivíduos sem câncer. MÉTODOS: O questionário Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) foi aplicado em 57 pacientes com diagnóstico de câncer de pulmão provenientes do Ambulatório de Oncopneumologia do Hospital São Paulo e em um grupo controle de 57 indivíduos participantes do Grupo de Ginástica Extra Penha. O teste de Mann-Whitney foi utilizado para comparar cada domínio entre os grupos. O primeiro modelo de regressão logística foi ajustado para sexo masculino, tratamento não cirúrgico, índice de Karnofsky e tabagismo, que foram incluídos como preditores. O segundo modelo foi ajustado para cada domínio do SF-36 para identificar aumento na proporção de estádios IIIB e IV. RESULTADOS: O grupo com câncer de pulmão e o grupo controle apresentaram, respectivamente, as seguintes pontuações médias para os domínios do SF-36: aspectos físicos, 29,39 ± 36,94 e 82,89 ± 28,80; aspectos emocionais, 42,78 ± 44,78 e 86,55 ± 28,77; capacidade funcional, 56,49 ± 28,39 e 89,00 ± 13,80; vitalidade, 61,61 ± 23,82 e 79,12 ± 17,68; dor, 62,72 ± 28,72 e 81,54 ± 19,07; estado geral de saúde, 62,51 ± 25,57 e 84,47 ± 13,47; saúde mental, 68,28 ± 23,46 e 82,63 ± 17,44; e aspectos sociais, 72,87 ± 29,20 e 91,67 ± 17,44. O modelo de regressão logística demonstrou que aspectos físicos, capacidade funcional e saúde mental foram preditores de estádios IIIB e IV. CONCLUSÕES: Os pacientes com câncer de pulmão apresentaram pior qualidade de vida em relação ao grupo controle, principalmente em relação aos aspectos físicos.Universidade Federal de São Paulo (UNIFESP)Centro Universitário São CamiloUNIFESPSciEL
