title: [Timing changes of apoptosis and proliferating cells nuclear antigen after intra-arteiral infusion chemotherapy for nasopharyngeal carcinoma].
abstract: OBJECTIVE
  To investigate the timing changes of apoptosis (APO) and PCNA after intra-arterial infusion chemotherapy for nasopharyngeal carcinoma.
  
  
  METHODS
  Ten patients were subjected to percutaneous superficial temporal artery catheterization and infusion of anticancer drugs: 5-Fu, DDp, BLM, nicotinamide. The biopsy of nasopharyngeal tumor tissues was performed before chemotherapy and 7 days after chemotherapy. Apoptotic cells were examined by TOT-mediated DUTP-fluorescein and labeling. The expression of proliferating cells nuclear antigen (PCNA) was detected with immunohistochemical staining.
  
  
  RESULTS
  AI of nasopharyngeal cancer cells before chemotherapy and 7 days after chemotherapy was 0.52% and 1.42%, PI was 42.4% and 51.2%.
  
  
  CONCLUSIONS
  Intra-arterial infusion chemotherapy not only induced apoptosis effectively, but also inhibited temporarily tumor cells proliferation in patients. The curative surgical treatment should be performed as soon as possible after chemotherapy.
