Outline of Final Research Achievements |
Fifteen patients who underwent thoracotomy for lung cancer were recruited. We analyzed the incidence of post-thoracotomy pain syndrome: PTPS, and predicting factors of PTPS. The incidence of PTPS two months after thoracic surgeries was 33%, and 13% of patients experienced severe pain (NRS≧5). These results are consistent with results of previous reports. The length of incision and duration of anesthesia/ surgery are found to be predicting factors, assuming that greater surgical stress would cause more inflammation and develop central sensitization which prolong pain. A retrospective study was performed for patients who underwent lung cancer surgery at seven university hospitals in Japan in 2013. The prevalence of PTPS at 3 and 6 months were 18% and 12% after lung surgery. In multivariate logistic regression analysis, preoperative analgesic use was found to be associated with PTPS. Female gender was significantly associated with PTPS 6 months.
