Abstract
Background
Pain is one of the most troublesome problems caused by malignancy. We evaluated the change in pain status according to observance of NCCN guidelines in lung cancer patients.
Methods
Lung cancer patients complaining of pain at admission were examined. The pain was assessed with visual analogue scale (VAS) for 20 days and moderate-to-severe pain was defined as more than VAS level 3. The guideline observance was classified as high (more than 80%), medium (50~79%) and low (less than 50%).
Results
Among the total 91 lung cancer patients with pain, 34 patients (37%) had moderate-to-severe pain. Their average VAS score at admission was 5.6. It decreased to 2.9 after a 20-day period of pain management. The time to reach a VAS less than 3 was 3 days in a high guideline observance group, while it took 6 days in a low observance group. In addition, the pain in the high observance group was controlled to less than 3 VAS level in 86% of patients, whereas only 25% of patients in the low observance group succeeded.
