Objective: To compare survival effects of comprehensive neck dissection (CND) and selective neck dissection (SND) for patients with nasopharyngeal carcinoma (NPC) with only regional failure.
Methods: A total of 294 recurrent T0N1-3M0 NPC patients who underwent neck dissection in Sun Yat-Sen University Cancer Center, Guangzhou, People's Republic of China, between January 1984 and February 2014, were enrolled in the survival and interaction analyses. Using propensity scores to adjust for potential prognostic factors, an additional well-balanced cohort of 210 patients was constructed by matching each patient who received SND with one patient who underwent CND (1:1); the differences were then compared between SND and CND in terms of overall survival (OS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant metastasis-free survival (DMFS).

Background: Sex-specific differences affect the evaluation, treatment, and prognosis of coronary artery disease. We tested the hypothesis that long-term outcomes of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) are different between women and men.
Methods And Results: Consecutive 1090 patients, referred for PCI and undergoing FFR measurements at the Mayo Clinic between October 2002 and December 2009, were included in this registry study.
