1979년 2월부터 1986년 9월까지 서울대학교 병원 치료방사선과에서 치료받은 상악동의 편평상피 암 환자 73예를 분석하였다. 41예에서는 수술과 수술후 또는 수술전 방사선치료를 병용하여 치료하였고 32예에서는 방사선치료만을 주치료로 시행하였다. 전체환자의 5년 생존율은 $40.4\%$였으며 방사선치료만을 주치료로 시행한 집단의 5년 생존율은 $22.1\%$였고 수술과 방사선치료를 함께 시행한 집단의 5년 생존율은 $65.3\%$였다. 치료 후 사망이 확인된 환자 가운데 상세한 치료실패 과정을 알 수 있었던 31예 중 잔류병소를 포함 국소치유실패를 나타냈던 경우가 22예($71.0\%$)였고 경부임파절 재발로 인한 치유실패가 6예($19.3\%$)였으며 인격전이로 인한 치유실패가 3예 ($9.7\%$)에서 나타났다. 그러므로, 상악동 암의 국소치유율을 증가시켜서 생존율을 높이기 위해서는 계획된 수술과 방사선 치료의 병용요법이 필요할 것으로 생각된다.

1980년 6월부터 1986년 12월까지 고신의료원 치료방사선과에서 방사선 치료를 받았던 상악동 암환자 79예에서 생존율과 치료실패에 대해 후향적으로 비교 분석하였다. 43예에서는 방사선 단독 치료를 하였고, 36예에서는 수술과 방사선 치료를 병용 하였다. 전체 환자들의 5년 생존율은 32$ \% $ 였으며 방사선 단독 치료만을 받았던 환자들의 5년 생존율은 23$ \% $였으며 수술과 방사선 치료를 병용한 환자들의 5년 생존율은 42$ \% $였다. 전체 환자 79예중 54예 (68.3$ \% $ )였고 국소치료 실채 및 원격전이가 동시에 나타난 경우가 16예(29.6$ \% $ )였으며 원격전이 단독으로 인한 경우가 1예였다. 상기와 같은 치료결과에서 상악동 암의 국소치료율을 높이고 생존율을 증가시키기 위해서는 방사선 단독 치료보다는 수술과 방사선 치료의 병용 요법이 필요할 것으로 사료된다.

CT findings of proven 25 malignant tumors of the maxillary sinus were retrospectively analyzed to be of help in the diagnosis and treatment. The results were follows: 1. Average age was 54 years old, and eighteen were males and seven were females with a ratio of 2.6:1 2. The most common histopathologic feature was squamous cell carcinoma (19 cases) and others were two cases of adenoid cystic carcinoma, one case of malignant fibrous histiocytoma, mucoepidermoid tumor, histiocytic lymphoma, unidentified malignant tumor. 3. CT findings were sinus opacificaqtion (4%), soft tissue mass (92%), low densities within soft tissue mass (44.%), air densities within soft tissue mass (24%), osteosclerosis (4%), bone destruction (92%), bone displacement (32%), fat plane obliteration (76%). 4. CT in the malignant maxillary sinus tumors approved the value in evaluation of tumor extension to nasal cavity, ethmoid sinus, orbit, infratemporal fossa, pterygopalatine fossa, pterygoid fossa, pterygoid muscle, cheek skin and intracranial cavity. 5. Twenty four cases (96%) were stage Ⅲ, stage Ⅳ according to AJCC TNM classification. 6. Bone findings were destruction, displacement, sclerosis and most frequent site of bone destruction was the medial wall of the antrum(92%). 7. Tumor growth pattern showed destructive pattern in 18 cases(72%), and squamous cell carcinoma showed destructive pattern. (P<0.05)

The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

Background: Head and neck cancer without distant metastases is amenable to various modalities of treatment. However, the stage at presentation is a very important determinant for treatment success. The present study was conducted to determine the stage-wise presentation of non-metastatic head and neck cancer patients from the hilly regions in Kumaon division of Uttarakhand, India. Materials and Methods: The hospital records for non-metastatic head and neck cancer patients from the only functional cancer centre of the region for the period of two-years (January 2012-December 2013) were included. Nasopharyngeal carcinoma was excluded due to its staging system being different. Non-squamous histopathologies were also excluded. Patients hailing from nearby regions of Uttar Pradesh and Nepal were excluded, as were patients from non-hilly regions of Kumaon. Results: Of the 271 patients of head and neck cancer, 27 with distant metastases at diagnosis were excluded from the analysis. Of the 244 eligible patient records, 90.1% (n=222) were male, and 9.9% (n=22) were female. The proportions of patients with carcinoma of the larynx, oropharynx, oral cavity, hypopharynx and maxillary antrum were 31.9% (n=78), 27.9% (n=68), 20.5% (n=50), 12.7% (n=31) and 1.2% (n=3). A further 5.7% (n=14) were diagnosed as having secondary involvement of neck nodes with unknown primaries. The proportion of patients presenting in stages I, II, III, IVA and IVB were 0.8% (n=2), 2.5% (n=6), 9.4% (n=23), 51.6% (n=126) and 35.7% (n=87) respectively. Conclusions: An abysmally low proportion (3.3%) of non-metastatic head and neck cancer patients presented in the early stages (I and II). A vast majority of the patients (88.1%) presented with stages IVA and IVB. Not only does this reflect a poor therapeutic outlook, but also exposes the dire need for programmes focusing on cancer awareness and early detection in the region.
