Statistical observations were made on the cases of carcinoma that developed in young patients of ages of 29 and under in the authors' clinic in a period of 20 years from 1936 to 1955.
And the results obtained were as follows:
The total number of patients was 30 (14 male and 16 female patients), and 5 cases were in their teens and 25 were in their twenties. The youngest patient was 16 years old.
The sites of origin were: with 11 cases in the upper jaw, with 5 in the esophagus, with 4 in the hypopharynx, with 3 in the pharynx, with 2 each in the nasopharynx and palate, and with 1 each in the nasal septum, tongue and larynx.
Histologically, there were 4 cases of undifferentiated cell cancer, 19 cases of squamous cell carcinoma and 3 cases of adeno-carcinoma, and the rest were unidentified.
The diagnosis was clinically so difficult that some of the cases were diagnosed wrongly. The histological examination with section tissues is considered to be the most reliable.
The prognosis was generally very bad and only two out of 18 cases of known prognosis has been cured, after taking over two years.
