Abstract
Advances in medicine have made long-term survival of cancer patients possible. Hence, it is now necessary to consider how to approach common symptoms, such as cancer-related pain, in these patients. In this study, we describe a lung cancer patient in whom relief of intractable thoracic pain caused by pleural metastasis was achieved through thoracic radiofrequency thermocoagulation (RF), improving his quality of life (QOL). The patient was a man in his 70s with right upper lobe lung cancer, left 9th -11th rib metastasis, and left thoracic pain associated with parietal pleural metastasis. The patient experienced insomnia and weight loss due to poor appetite caused by opioid analgesics and inadequate pain control. Therefore, RF was performed as interventional treatment, resulting in a decrease in the numerical rating scale score from 10/10 to 2/10, and an improvement in QOL. In cases wherein long-term survival is expected, a long-term treatment plan for chronic cancer-related pain, which has a tendency to become persistent, becomes necessary. RF for the nerve roots might be a viable option for pain caused by pleural metastasis in cancer survivors.
