The result of neutron therapy on head and neck cancer using KCCH -Cyclotron neutron which had been using from October 1986 to September 1989 in the Korea Cancer Center Hospital. Among the total of 27 patients the cases of malignant salivary gland tumor were 14 and the cases of advanced head and neck cancer of AJCC stage IV were 13. The local control rate was 80% in malignant salivary gland tumor and 46.2% in advanced head and neck cancer. The 2 year survival rate was 60% in malignant salivary gland tumor and 38.5% in advanced head and neck cancer. Although there was no significant difference in prognosis according to the pathologic types, squamous cell carcinoma revealed a pattern of poor prognosis. The major complication from the neutron therapy had developed 7.1% in malignant salivary gland tumor and 23.1% in advanced head and neck cancer. In conclusion, neutron therapy is superior in the treatment of malignant salivary gland tumor and also effective in the treatment of advanced head and neck cancer when it can avoid to treat some site of low tolerance.

Background: Patient delay can contribute to a poor outcome in the management of head and neck cancers (HNC). The main objective of the present study was to investigate the factors associated with patient delay in our population. Materials and Methods: Patients with cancers of the head and neck attending a regional cancer center of North East India were consecutively interviewed during the period from June 2014 to November 2014. The participation of patients was voluntary. The questionnaire included information on age, gender, residential status, educational qualification, monthly family income, any family history of cancer, and history of prior awareness on cancer from television (TV) program and awareness program. Results: Of 311 (n) patients, with an age range of 14-88 years (mean 55.4 years), 81.7% were males and 18.3% females (M:F=4.4). The overall median delay was 90 days (range=7 days-365 days), in illiterate patients the median delay was 90 days and 60 days in literate patients (P=0.002), the median delay in patients who had watched cancer awareness program on TV was 60 days and in patients who were unaware about cancer information from TV program had a median delay of 90 days (p=0.00021) and delay of <10 weeks was seen in 139 (44.6%) patients, a delay of 10-20 weeks in 98 (31.5%) patients, and a delay of 20-30 weeks in 63 (20.2%) patients. Conclusions: Education and awareness had a significant impact in reduction of median patient delay in our HNC cases.

Cancer of the head and neck is an uncommon disease accounting for 5 % of all cancers. In an anatomic area so readily visible and palpable for examination without special and expensive diagnositic tools, it is unfortunate that many patients still present with advanced diseases. Since the prognosis is so intimately related to stage of disease, it is very important to detect the earliest stage of cancer with a complete head and neck examination. In the evaluation of cancer at any anatomic site, the description of the extent of the lesion is important. Not only does proper staging of the tumor lead to make decision of the most appropriate treatment, it also serves as a guide for the results of treatment. Proper staging demands a careful clinical assesment of the extent of the cancer. The current staging system for head and neck cancer uses the TNM system devised by American Joint Committee for Cancer Staging and End Result Reporting. T represent the primary tumor, N, regional nodal metastases, and M, distant metastases. The detection, diagnosis, and appropriate treatment of eary cancer will result in improved survival.

Background: Mean platelet volume (MPV) is a marker which has been investigated in many cancers but data for head and neck lesions are limited. We aimed to study the MPV levels in head and neck cancers as a diagnostic marker. Materials and Methods: A total of 96 head and neck cancer patients and 31 control patients who did not meet exclusion criteria were enrolled in the study. The cancer locations, the platelet and MPV levels at the first diagnosis time were collected. Results: The head and neck cancer location distribution between these patients was 2 (2.1%) buccal, 9 (9.4%) tongue, 6 (6.3) lip, 1 (1%) gingiva, 1 (1%) hypopharynx, 1 (1%) ear, 58 (60.4%) larynx, 2 (2.1%) maxilla, 2 (2.1%) nasal, 1 (1%) nasopharynx, 2 (2.1%) palatal, 3 (3.1%) primary unknown, 1 (1%) retromolar, 1 (1%) thyroid, 2 (2.1%) tonsil, and 4 (4.2%) salivary gland. MPV levels were significantly different between cancer and control group (p=0.002). The cut-off point for MPV predicting head and neck cancer is >10 fL (sensitivity=55.21, specificity=87.10). Conclusions: MPV level increase, a readily assessable parameter which does not bring extra costs can warn us regarding head and neck cancer risk.

The causes of treatment failure in head and neck cancer are locoregional recurrence, distant metastasis and second primary cancer. The favorite sites of second primary cancer are head and neck, lung and esophagus. But, the incidence of stomach cancer in Korea is the highest of all, high incidence of stomach cancer is expected in head and neck cancer patients. We experienced 2 cases of stomach cancer after successful treatment of primary head and neck cancer at Kang Nam St. Mary's hospital. The first case was a 60-year-old male with nasopharyngeal non-keratinizing carcinoma(stage III, T1N1M0). He received three cycles of induction chemotherapy including cisplatin and 5-fluorouracil followed by radiotherapy which resulted in complete response. Five months after completion of radiotherapy. stomach adenocarcinoma(stage IV, T4N2M1) was diagnosed. He received one cycle of FAM chemotherapy and died 4 months after diagnosis of stomach cancer. The second case was a 50-year-old male with pyriform sinus squamous cell carcinoma(stage II, T2N0M0). He received curative partial pharyngolaryngectomy followed by radiotherapy which result in free of disease. Four months after completion of radiotherapy. stomach adenocarcinoma(stage IV, T4N2M1) was diagnosed. Bypass gastrojejunostomy was performed. The screening test for stomach cancer including upper gastrointestinal X-xay series and/or endoscope of the stomach should be performed periodically for the patients with head and neck cancer in Korea.

Small cell carcinoma of larynx has been reported as a rare disease occurring in 0.5% of larynx cancer. This tumor is known as one of the most lethal of all malignancies and associated with early recurrence and distant metastasis, leading into death. We experienced a case of a 70-year old male patient, who had admitted for sore throat and dysphagia and diagnosed as small cell carcinoma of larynx. We present small cell carcinoma of larynx with a brief review of literature.

Brachytherapy has been proved to be an effective method for the purpose of increasing radiation dose to the tumor and reducing the dose to the surrounding normal tissue. In head and neck cancer, the rationale of brachytherapy is as follows; Firstly, early small lesion is radiocurative and the major cause of failure is local recurrence. Seondly, it can diminish evidently the dose to the normal tissue especially masseteric muscle and salivary gland. Thirdly, the anatomy of head and neck is suitable to various technique of brachytherapy. On background of accumulated experience of LDR iridium brachytherapy of head and neck cancer for the last 15 years, the author reviewed the history of radioisotope therapy, the characteristics of radionuclides, and some important things in the method, clinical technique and treatment planning. The author analyzed the clinical result of 185 cases of head and neck cancer treated in the Korea Cancer Center Hospital. Finally the future prospect of brachytherapy of head and neck cancer is discussed.

The actual burden of head and neck cancer in India is much greater than reflected through the existing literature and hence can be regarded as a 'tip of iceberg' situation. This has further been evident by the recent reports of 'Net-based Atlas of Cancer in India'. South-east Asia is likely to face sharp increases of over 75% in the number of cancer deaths in 2020 as compared to 2000. Since the percentage increase of Indian population has been nearly twice that of the world in last 15 years there is a likelihood of increase in cancer burden with the same proportion. The distribution of population based cancer registries is grossly uneven with certain important parts of the country being not represented at all and hence the current cancer burden is not reflected by registry data. However, the pathetic situation of health care system in major parts of the country as also emphasized by the World Bank, is not suitable to provide anywhere near accurate data on cancer burden. Head and neck cancer (including thyroid lesions) is third most common malignancy seen in both the sexes across the globe but is the commonest malignancy encountered in Indian males. Also oral cavity cancer is the most prevalent type amongst the males and one of the highest across the globe. This article reviews the latest global and national situation with an especial emphasis on head and neck cancer. Furthermore this review focuses on burden in different sub sites at national and global levels.

Head and neck cancer is the sixth most common type of human cancer worldwide. Squamous cell carcinoma is the most common cancer of the head and neck. Since $^{18}F-FDG$ PET is very sensitive to detecting squamous cell carcinoma, it has been widely used in patients with head and neck cancers for initial staging, management of recurrent cancers, and therapeutic monitoring. According to clinical research data, $^{18}F-FDG$ PET is expected to be a very helpful diagnostic tool in the management of head and neck cancer.

Brown tumor is characterized as the classic skeletal manifestation of advanced hyperparathyroidism. It is considered as a benign tumor because of its reparative cellular process. We have experienced 6 patients of brown tumor with hyperparathyroidism, enrolled at Korea Cancer Center Hospital from November 2007 to September 2013. Five of the patients were diagnosed as parathyroid adenoma and treated with parathyroidectomy, and one female patient was diagnosed as parathyroid carcinoma and treated with parathyroidectomy and thyroid lobectomy. These six cases demonstrated that early parathyroidectomy after diagnosis helps to relieve symptomatic pain, normalize calcium level, treat hyperparathyroidism, prevent tumor progression and also prevent osteoporosis in bones. We present these 6 patients with a review of literature.
