    Background:
    While most cancer therapies are associated with toxicities, a major component of cancer treatment is to reduce cancer-related symptoms and impairment of function. Assessing how well this goal is achieved is dependent on accurate assessments of baseline symptoms prior to initiation of therapy. The objectives of this study were to describe the symptom burden of treatment-naïve lung cancer patients and to examine demographic and disease factors that correlate with symptom severity.
    
    Method:
    Symptom data from 460 treatment-naïve patients with lung cancer were obtained using the validated MD Anderson Symptom Inventory via a 0-10 numeric rating scale. Descriptive statistics were used to summarize patient demographic and clinical characteristics. Differences in symptom severity, symptom interference and quality of life by disease stage and histology were examined using either t-test or ANOVA. Multiple linear regression analysis was performed using age, gender, tumor stage and histology to determine significant predictors of pain and shortness of breath.
    
    Result:
    The most severe symptoms were fatigue, disturbed sleep, distress, pain, shortness of breath, sadness and drowsiness. About 62% of patients had at least one moderate to severe (rated 5 or greater) symptom, while 48% had at least one severe (rated 7 or greater) symptom. Disturbed sleep, distress, shortness of breath, sadness, and drowsiness were reported to be severe by at least 16% of the patients. As expected, patients with advanced stage had significantly more severe symptoms. Patients with small-cell carcinoma reported the most severe pain and shortness of breath. Multiple linear regression analysis showed that stage was a significant predictor of pain severity while controlling for histology, age and gender. Patients with advanced stage had a pain level that was 1.2 higher than patients with early stage disease (95% CI= 0.5 – 1.8, p<0.001. For shortness of breath, both histology and stage were significant predictors of severe levels while controlling for age and gender. Patients with advanced stage had a shortness of breath level that was 0.9 higher than patients with early stage disease (95% CI= 0.4 – 1.6, p<0.001). Patients with small cell carcinoma had a shortness of breath level that was 1.5 higher than those with adenocarcinoma (95% CI= 0.35 – 2.6, p<0.01).
    
    Conclusion:
    In conclusion, as much as 62% of treatment-naïve patients with lung cancer reported at least one moderate-to-severe symptoms prior to initiation of cancer therapy. This high burden suggests that symptoms should be assessed routinely and tracked in parallel with cancer treatment.
