|
The records of 473 patients with intraoral squamous cell carcinoma, who had managed in Gospel Hospital from Jan. 1979 to Dec. 1985, were reviewed in order to know incidence, topographic distribution, mode of treatment, and survival rate. The results of the study are as
} follows.
1 . The age distribution was variable, which was from 7 years old to 88 years old, and the mean age was 54 years, and 80.3% was
f
occurred in men and 19.7% was occurred in women, especially at tonsil, the ratio of men to women was 10 to 1.
2. Pharynx (21.4%) and tongue (19.7%) was the most common site
r of the primary carcinoma in the mouth, and the buccal mucosa (0.8%), gingiva (3%), faucial arch (0.6%), and the lip (4.9%) showed relatively lower incidence rate.
3. The mean duration, which was defined of the period from symptom onset to first hospital visit, was 10.3month, especially 26.4month in lip, below 5month in gingiva.
4. The size of the carcinoma which was measured on the first visit was from 1cm to 8cm, the mean size was 4.4cm, and in palate, the size (5.1cm) was usually large and that in the lip was small (3.5cm).
5. In N-stage, 61.3% was beyond N-1 at tongue, and high value was shown in pharynx and hypopharynx also. The most common regional metastatic lymphnode was upper posterior cervical Iymphnode (42.9%).
6. In type of treatment, only radiotherapy was 29.41/o, and combined tre, tment with chemical, surgical, and radiotherapy was 51.0%.
7. The 2 years survival rate was 39% in overall. At tongue the 2 years survival rate was 58% compared with other site. On T-stage, that was 67%, 43%, 27%, 25% in T1, 1`2, 73, T4. The 2 years survival rate was 54% on the cases without regional lymphnode metastasis, 26% with metastasis. On N-stage, that was 43%, 25%, 13% in Nl, N2, N3. On the cases with regional lymphnode metastasis, the 2 years survival rate was 14% at tongue compared to that of other site.
8. On the cases with distant metastasis, the 2 years survival rate was 29% compared to 38% at the cases without distant metastasis.
