Cancer of the larynx is the most common malignant neoplasm of head and neck and has a generally favorable prognosis. But its incidences of lymph node metastasis and recurrence depend on the primary site of lesion. Especially, supraglottic carcinoma tends to involve the cervical lymph node with easy. We have analyzed retrospectively 49 cases of supraglottic carcinoma treated surgically with or without radiotherapy from March 1986 to February 1992 at the department of otolaryngology, Pusan National University Hospital to find out the incidence of ipsilateral and contralateral lymph node metastasis and to establish the indication of neck dissection followed by T stage. The incidence to the ispilateral and contralateral cervical lymph node metastasis in patients with lateral (aryepiglottic fold) lesions is higher than that in those with midline (epiglottis) lesion. And average incidence of isplateral lymph node metastasis was 51.0% regardless of T stage. Therefore routine neck dissection should be considered in surgical treatment of supraglottic carcinoma, especially, over T2 stage.

Purpose : The purpose of this study was to evaluate the efficacy of curative radiotherapy in the management of supralottic cancer. Materials and Methods : Twenty-one Patients with squamous cell carcinoma of the supralottis were treated with radiotherapy at Gyeongsang National University Hospital between 1590 and 1994. Median follow-up period was 36 months and 95% were observed for at least 2 years. Results : Actuarial survival rate at 5 years was 39.3% for 21 patients. The 5-rear actuarial survival rate was 75.0% in Stage I, 42.9% in Stage II, 33.3% in Stage III and 28.6% in Stage IV(p=0.54), The 5-year local control rate was 52.0% for 21 patients. The 5-rear local control rate was 75.0% in Stage I, 57.1% in Stage II, 66.7% in Stage III, and 28.6% in Stage IV(p=0.33). Double primary cancer was developed in 3 patients and those were all esophageal cancers. Conclusion : In early stage(Stage I and II) supralottic cancer, curative radiotherapy would be a treatment of choice and surgery would be better to be reserved for salvage of radiotherapy failure. In advanced stage(Stage III and IV), radiotherapy alone is inadequate for curative therapy and combination with surgery should be done in operable patients. This report emphasizes the importance of esophagoscopy and esophagogram at the follow-up of patients with supralottic cancer.

Sixty-six patients with squamous cell carcinoma of the supraglottic larynx received irradiation with curative intent between 1979 and 1985 were retrospectively analysed. All patients had a minimum follow-up of 4 years. Of the entire group consisting of $73\%$T3 and T4 lesions and $58\%$ lymph node metastases, a 5-year acturial survival rate was $31.3\%$. A 5-year acturial survival rates for stage II, III and IV were $60.7\%,\;45.7\%\;and\;13.5\%$ respectively (p<0.05). Patients without lymphnode metastases had better survival rate than those with postive lymphnode metastases $(54.8\%\;vs\;12.2\%)$ (p<0.005). Surgical salvage rate w8s 4/7 $(57\%)$. Three patients developed distant metastases. Major complications requiring surgery were seen in $11\%$, Radiation therapy alone with surgical salvage was an effective, voice preserving treatment for stage I, II and selected III carcinoma of the supraglottic carcinoma, however planned combined treatment with surgery and radiation therapy is advised for stage III and IV carcinoma of the supraglottic larynx with resectable neck disease.

Purpose : To determine the incidence and prognostic effect of p53 expression in patients with advanced supralottic cancer. Materials : Twenty-one cases of total 48 advanced supraglottic cancer patients who received postoperative adjuvant radiation therapy were evaluated by immunohistochemical staining employing p53 monoclonal antibody. Result : Three out of six stage III patients and four out of fifteen stage IV patients showed p53 expression without statistically significant difference (p=0.608). Five year survival rates are $93\%$ in p53 negative, $80\%$ in p53 positive patients and there was no significant difference(p=0.776). p53 expression does not show statistically significant correlation with primary tumor status(p=0.877), lymph node status(p=0.874) and age(p=0.64). Conclusion : There was no statistically significant correlation between traditionally known risk factors and p53 expression.

Laryngeal cancer is the commonest of all head and neck malignancies and, in Korea, constitutes approximately 2.3% of all malignancies among males. Survival rate is rather higher than any other head and neck malignancies. Treatment results of 121 laryngeal cancer patients were analyzed. 1. Glottic region 44%, supraglottic 41%, subglottic 8%, transglottic 7%. 2. Rate of cervical metastasis according to T stage was 19% in T2 stage, 47% in T3 stage, 69% in T4 stage. 3. Overall 3-year NED survival rate was 65% and showed stage I 93%, stage II 76%, stage III 63%, stage IV 53%. 4. Glottic cancer showed much better prognosis(3-year NED 82%) than supraglottic cancer(3-year NED 58 %). 5. According to treatment modality, complication rates in surgery with postoperative radiation was higher than in surgery along and disproportionally higher in salvage surgery after failed curative radiation.
