Abstract

Background: Systemic inflammation plays an important role in the initiation, promotion, and progression of lung carcinogenesis. In patients with non-small cell lung cancer (NSCLC), fibrinogen levels correlate with neoplasia. Here we compared the effects of pulmonary rehabilitation (PR) with chest physical therapy (CPT) on fibrinogen and albumin levels in patients with LC and previous inflammatory lung disease awaiting lung resection.

Methods: We conducted a randomized clinical trial with 24 patients who were randomly assigned to Pulmonary Rehabilitation (PR) and Chest Physical Therapy (CPT) groups. Each group underwent training 5 days weekly for 4 weeks. All patients were assessed before and after four weeks of training through clinical assessment, measurement of fibrinogen and albumin levels, spirometry, 6-minute Walk Test (6MWT), quality of life survey, and anxiety and depression scale. PR involved strength and endurance training, and CPT involved lung expansion techniques. Both groups attended educational classes.

Results: A mixed between-within subjects analysis of variance (ANOVA) revealed a significant interaction between time (before and after intervention) and group (PR vs. CPT) on fibrinogen levels (F(1, 22)=0.57, p<0.0001) and a significant main effect of time (F(1, 22)=0.68, p=0.004). Changes in albumin levels were not statistically significant relative to the interaction effect between time and group (F(1, 22)=0.96, p=0.37) nor the main effects of time (F(1, 22)=1.00, p=1.00) and group (F(1, 22 )=0.59, p=0.45). A mixed between-within subjects ANOVA revealed significant interaction effects between time and group for the peak work rate of the unsupported upper limb exercise (F(1, 22)=0.77, p=0.02), endurance time (F(1, 22)=0.60, p=0.001), levels of anxiety (F(1, 22)=0.60, p=0.002) and depression (F(1, 22)=0.74, p=0.02), and the SF-36 physical component summary (F(1, 22)=0.83, p=0.07).

Conclusion: PR reduced serum fibrinogen levels, improved functional parameters, and quality of life of patients with LC and inflammatory lung disease awaiting lung resection.
