Significance of desquamated cells of nasopharyngeal mucosa based on 1081 cases of nasopharyngeal carcinoma.
The results of a general investigation based on the cytological examination of swabs taken from nasopharyngeal mucosa of 1081 people were as follows. 1. Occupation: mainly workers; 687 males, 394 females; ratio 1.7:1. 2. Smear examinations revealed 450 normal cells (41.62%), 586 inflammatory cells (54.21%), 35 precarcinomatous cells (3.22%), and 7 carcinomatous cells including pseudo-positives (0.65%). 3. Our conclusion is that the inflammatory hyperplastic cytopoiesis may be a precarcinomatogenotropic factor. 4. No suspicious smear should be overlooked in the course of a general investigation, in order to work out a correct alteration. 5. The precarcinomatous cytopoietic alteration and an early diagnosis of nasopharyngeal carcinoma may be confirmed by a trace resulting from the examination of desquamatory cells. 6. An amply prepared prophylaxis and early treatment may be achieved by confirmation of the early diagnosis of the precarcinomatous stage and the early carcinomatous stage by subsequently broadening the general investigation in view of the fact that the morbidity from carcinoma in that district was 0.65% according to our general investigation in the test area.
