Analysis of prognostic factors in cases with nasopharyngeal carcinoma

We analyzed prognostic factors of 38 cases with nasopharyngeal carcinoma. The 3-year disease-specific survival rate was 50%, and the 3-year locoregional control rate was 58%. The survival rate in the elderly group was low, but there was no significant difference. In terms of T stage, advanced cases did not show reduced survival rate and locoregional control rate. Regarding N stage, advanced cases showed low survival and locoregional control rates, but there was no significant difference. In terms of stage classification, there was also no significant difference. The group of WHO type 1 showed lower survival rate compared to the group of WHO types 2 & 3, but there was no significant difference. On the other hand, the group of WHO type 1 showed a lower locoregional control rate with a significant difference. Based on these findings, age, T, N, stage, and histological type were not unfavorable prognostic factors, however, WHO type 1 was a poor prognostic factor in the locoregional control rate of neopharyngeal carcinoma.
