      • Abstract

      Background

      Lung cancer is a commonly diagnosed cancer, and the leading cause of cancer death around the world. Over 80% of lung cancer patients in México are diagnosed in advanced stage. Common symptoms include cough, dyspnea, weight loss, and chest pain. Dyspnea is one of the most common symptoms in patients with lung cancer at initial presentation with a prevalence of 55–90%. The intensity of dyspnea is an important and validated factor for assessment of quality of life (QOL) in cancer patients. In addition, improvement of health-related QOL and symptoms, such as dyspnea, are related with the efficacy of chemotherapeutic regimens and favorable outcome in lung cancer. In this study, we investigated the association between the degree of dyspnea and clinical outcomes to identify the prognostic role of dyspnea in hispanic patients with non-small cell lung cancer (NSCLC).

      We retrospectively reviewed lung cancer database of Centro Oncologico Estatal ISSEMYM. From 2013 to 2016 we enrolled patients with diagnosis of advanced NSCLC. Clinicopathological information on age, sex, smoking history, histologic type, stage, Eastern Cooperative Oncology Group (ECOG) performance status, clinical outcomes and evaluation of symptoms of dyspnea at diagnosis using modified Medical Research Council (mMRC) scores from each patient were recorded.

      A total of 120 patients with diagnosis of NSCLC were identified, of these only in 65 patients (54%) the symptom of dyspnea were detected and evaluate using modified Medical Research Council (mMRC) scores at initial diagnosis. The median age was 58 years. Among those patient with dyspnea and mMRC scores available at diagnosis, 29 (45%) patients had an mMRC score ≥ 2, while 36 (55 %) had an mMRC score < 2. In multivariate analysis, poor performance status and an mMRC score ≥2 were found to be significant prognostic factors for patient survival. The overall median survival for all patients was 18 months. The overall survival of patients with dyspnea (mMRC grade 2 or higher) was significantly lower than that for patients without or low grade dyspnea (median survival, 17 months vs. 35 months, p<0.036).

      In conclusion, this study showed that the dyspnea mMRC mMRC grade 2 or higher in Hispanic patient with NSCLC were significantly associated with poor prognosis. Therefore, clinicians should pay more attention to evaluation and management of dyspnea.
