Abstract

Background:

Most patients with lung cancer are diagnosed at advanced stages of the disease, where chemotherapy plays an important role. This prospective study was conducted to determine the impact of palliative chemotherapy on quality of life (QOL) in advanced-stage lung cancer patients.

Methods:

QOL in lung cancer out-patients was assessed at diagnosis and end of treatment using the EORTC QLQ-C30 questionnaire. Changes in mean QOL scores were calculated. The correlation between patients’ tumor response and change in QOL scores was also studied. Scoring was done according to the EORTC manual and results were analyzed using SPSS statistical package.

Results:

Out of 52 patients, 46 (88.46%) were men and six (11.54%) were women. After chemotherapy, patients’ overall QOL score improved significantly (P = 0.005). Cognitive functioning significantly worsened (P = 0.01). Physical functioning (PF) and emotional functioning (EF) scores improved, while role functioning (RF) and social functioning (SF) scores worsened. Pain, dyspnea, and sleep significantly improved (P = 0.001, P = 0.001, and P = 0.005 respectively). On the other hand, nausea, vomiting (P = 0.000), diarrhea (P = 0.004), and financial difficulties (P = 0.009) worsened. Overall QOL improved in patients with partial tumor response (PR) and stable disease (SD) (P = 0.044 and P = 0.000, respectively), but worsened in progressive disease group (PD) (P = 0.648). Symptom scores improved markedly in PR and SD groups. Chemotherapy toxicity was maximum in PD group (P = 0.028).

Conclusion:

Global quality of life and symptom control significantly improved in lung cancer patients after chemotherapy. Deterioration of cognitive functioning, increased financial burden, and chemotherapy-related toxicity were noteworthy. Changes in QOL were coherent with patients’ tumor response.
