Is photodynamic therapy associated with an improvement in survival in patients with irresectable hilar cholangiocarcinoma?
This prospective clinical cohort study has demonstrated that radical surgery and palliative Photofrin-PDT are associated with an increased survival in patients with hilar cholangiocarcinoma.
Patients with COPD had a significantly higher risk of developing lung cancer than healthy people. However, there was a protective effect of T2DM for lung cancer among patients with COPD. Further investigation may be needed to corroborate the mechanism or bring up reliable reasons.
