Thirty five lesions of 35 patients with locally advanced malignant tumors of head and neck were received thermoradiotherapy with ultrasound and/or 915 MHz microwave. Most of all patients were failed with previous conventional therapeutic trial. Hyperthermia had been done immediately after radiotherapy, twice a week, $43^{\circ}C$ for one hour and radiotherapy had been done 5 fractions per week with a fraction size of 2 Gy up to total 30 to 60 Gy. Conclusions are as follows; 1) Total response rate (CR+PR) of thermoradiotherapy with microwave and ultrasound was 80%. 2) Tumor depth, minimum temperature of tumor center, number of heat fraction and irradiation dose were statistically significant factors affecting response. 3) Hyperthermia with microwave and ultrasound can be used efficiently to control locally advanced malignant tumors in head and neck whether previously received near tolerance dose of radiotherapy or not.

Hemangiomas are the most common benign tumors or tumor-like malformations of blood vessels or blood filled cavernous spaces. Hemangiomas of the oral cavity represents 14% of all hemangiomas. Most hemangiomas are detected by one year of age and most commonly occurred in the lips, tongue, buccal mucosa and palate. But hemangiomas are sometimes reported in adults. We report one case of extensive hemangioma of the tongue in adult. Our case is a 48-year-old male who presented with a hemangioma occupying entirely two-third of the tongue. Treating those lesions pose a challenge to the surgeon. This paper discusses one case of extensive tongue hemangiomas treated with alcoholic sclerotherapy with satisfactory results supporting this particular approach in the management of these lesion.

Patients who have the head and neck cancer are usually treated by surgery, radiation therapy, chemotherapy, or combinations of them. These treatments can induce variable degree of aspiration with dysphagia. The type and severity of aspiration depends on the size and location of the original tumor, the structures involved, and the treatment modality used for treatment. The management of aspiration after the head and neck cancer's treatment begins with an accurate evaluation for the cause and mechanism of aspiration through modified barium swallow (MBS) and fiberoptic endoscopic examination of swallowing (FEES). Then, the clinician can use postures, maneuvers, and exercises to treat the swallow disorder and to help the patient achieve optimal function. To achieve optimal swallowing without aspiration, multidimensional rehabilitation by various medical personnel is definitely necessary.

Background and Objectives The purpose of the present study was to evaluate the usefulness of a posterior-based buccinator myomucosal flap (the Bozola flap) for the reconstruction of oral cavity defects after tongue cancer resection. Subjects and Method Fifteen patients who underwent from 2014 to 2016 reconstruction of the oral cavity with a Bozola flap after surgical management of tongue cancer were enrolled in the study. Patient characteristics, surgical outcomes, and complications associated with the Bozola flap were evaluated. Results The flap was successfully harvested and transferred in all patients. The mean flap harvesting time was 25.3 min. The donor site was closed primarily in 14 patients, and a buccal fat pad flap was used in one patient. Although partial necrosis of the flap occurred in two patients, no other major complications were noted. Conclusion The results of this study demonstrate that the Bozola flap is a good option for reconstruction of moderate sized oral cavity defects in tongue cancer patients.

Head and neck cancer is the 6^th most frequently diagnosed solid tumor in the world. Alcohol consumption, smoking, and HPV infection are associated with the incidence of head and neck squamous cell carcinoma (HNSCC). Although a multidisciplinary approach is a key strategy for the treatment of locally advanced HNSCC, systemic therapy is the mainstream of recurrent or metastatic HNSCC treatment. Stage IV HNSCC has a relatively poor prognosis with median overall survival of around one year. There have been many clinical trials to investigate the efficacy of target agents in the treatment of HNSCC. In the HPV-negative HNSCC, TP53 and CDKN2A are the most commonly mutated genes. In the HPV-positive HNSCC, the PI3K pathway is frequently altered. EGFR, PI3K, cell cycle pathway, MET, HRAS, and IL6/JAK/STAT pathway are explored targets in HNSCC. In this study, we review the target pathways and agents under research. We also introduce here umbrella trials of recurrent or metastatic HNSCC conducted by the Korea Cancer Study Group. The combination of target agents with immune checkpoint inhibitors or cytotoxic chemotherapies would be a future step in the precision medicine of HNSCC treatment.

Background: The organ preservation approach of choice for the treatment of locally advanced head and neck cancers is concurrent chemoradiation with three weekly high doses of cisplatin. Although this is an efficacious treatment policy, it has high acute systemic and mucosal toxicities, which lead to frequent treatment breaks and increased overall treatment time. Hence, the current study was undertaken to evaluate the efficacy of concurrent chemoradiation using 40 mg/m2 weekly cisplatin. Materials and Methods: This is a single institutional retrospective study including the data of 266 locally advanced head and neck cancer patients who were treated with concurrent chemoradiation using 40 mg/m2 weekly cisplatin from January 2012 to January 2014. A p-value of < 0.05 was taken to be significant statistically for all purposes in the study. Results: The mean age of the study patients was 48.8 years. Some 36.1% of the patients had oral cavity primary tumors. The mean overall treatment time was 57.2 days. With a mean follow up of 15.2 months for all study patients and 17.5 months for survivors, 3 year local control, locoregional control and disease free survival were seen in 62.8%, 42.8% and 42.1% of the study patients. Primary tumor site, nodal stage of disease, AJCC stage of the disease and number of cycles of weekly cisplatin demonstrated statistically significant correlations with 3 year local control, locoregional control and disease free survival. Conclusions: Concurrent chemoradiotherapy with moderate dose weekly cisplatin is an efficacious treatment regime for locally advanced head and neck cancers with tolerable toxicity which can be used in developing countries with limited resources.

Objectives: This study was designed to investigate the significance of serum SCC antigen, CA 19-9, CA 125 level and DNA microsatellite alterations (MSA) as prognostic factors and indicators for recurrences in the pre-treatment and post-treatment state, respectively in head and neck cancer patients. Materials and Methods: 120 patients who received curative treatment for head and neck cancer from 1995 to 2000 were followed up successfully, and were analyzed retrospectively. Thirty healthy subjects served as normal controls. Serum SCC Ag levels were measured by microparticle enzyme immunoassay technique via IMX SCC assay, CA 19-9 levels were measured by CA 19-9 RIA test kit, and CA 125 levels were measured by CA 125 IRMA kit. MSA were identified after PCR amplification. Heterozygosity was considered lost if the ratio of one allele was significantly decreased (>50%) in serum DNA compared with normal DNA from lymphocytes. Results: Preoperative tumor markers were higher in cancer patients than control, but not significant. Postoperative SCC Ag levels were lower than preoperative levels. The SCC Ag levels were remained low in no evidence of disease (NED) group, but increased in locoregional recurrence and distant metastasis group. CA 19-9 and CA 125 levels showed no correlation between levels and recurrences and were not decreased significantly after primary tumor removal. MSA were detected in five out of 21 cases, and highly detected in distant metastasis group. Conclusion: SCC Ag seems to be a helpful serum tumor marker for early detection of recurrence and distant metastasis of head and neck cancer after curative treatment. But, CA 19-9 and CA 125 were not reliable markers for head and neck tumors. MSA were not statistically significant because of the small number of study group. However they may be helpful for screening serum molecular markers for early detection of distant metastasis of head and neck cancers.

레이저를 이용한 내시경하 상후두부분절제술은 술전에 정확한 병기판정으로 초기 국소병변의 선택을 신중하게 하고 경부 림프절전이의 치료를 효율적으로 시행하는 경우 기존의 수술법과 유사한 생존율을 얻을 수 있었다. 환자의 상태에 따라서 충분한 수술시야를 확보하는데 어려움이 있으며, 병변의 위치에 따라서 술중 절제연의 확인이 힘들다는 제한점을 고려해야 하며, 술 후 발생할 수 있는 출혈, 부종, 오연 등의 합병증에 대비하기 위하여 술 전 기관절개술이 유용할 것으로 생각된다.
