General cell‐mediated immune (CMI) functions in NPC patients were investigated by the in vitro Mantoux and in vitro lymphocyte response to PHA assays. Thirty‐eight (50%) of 76 untreated NPC patients were hyporesponsive in the Mantoux assay compared to 27 (25%) of 110 control patients. Forty‐three (65.2%) of 66 untreated NPC patients also showed lymphocyte hyporesponsiveness to PHA compared to 15 (15.5%) of 97 control patients. Combined deficiencies were observed in 35 (42.2%) of 83 NPC patients compared to only 2 (3.3%) of 61 control patients. No difference in the frequency of immuno‐deficiency was observed between “early” and “late” disease patients. CMI functions of treated “remission” NPC patients were found to be impaired to the same extent as those of untreated NPC patients.
