Background and Objectives: Neck metastasis is one of the most important prognostic factor in head and neck squamous cell carcinoma. Recently, elective neck dissection has been widely accepted for accurate pathologic staging and elective treatment of neck. Occult metastasis rate of laryngeal cancer varies widely depending upon authors. To evaluate the rate and characteristics of occult metastasis and efficacy of the elective neck dissection in clinical N0 laryngeal cancer, we performed this study. Materials and Method: Seventy two patients (supraglottic cancer: 19 cases, glottic cancer: 53 cases) who underwent surgery for laryngeal cancer as an initial treatment from 1993 to 2002 were evaluated. All was underwent elective neck dissection at the time of surgery for the primary treatment. The record of patients and pathologic report were reviewed retrospectively. Results: Occult metastasis rate of supraglottic and glottic cancer were 42.1% (8/19) and 9.4% (5/53), respectively. According to T stage, the occult meastasis of supraglottic and glottic cancer was 20%, 0% in T1, 36.4%, 0% in T2, 100%, 40% in T2, 100%, 20% in T4, respectively. Occult metastasis was mostly confined within level II (69.2%), III (76.9%), IV (23.1%). Conclusion: Based on ours results, elective neck dissection might be needed in treating of clinically N0 all supraglottic cancer and advanced T3, T4 glottic cancer.

Large cell neuroendocrine carcinoma is a rare epithelial neuroendocrine malignancy and is preferentially located in gastrointestinal tract and pancreas. Cases of large cell neuroendocrine carcinoma have been reported in many other locations, including the thymus, gallbladder, prostate, larynx, salivary glands, nasopharynx, tonsil and mastoid. However, primary sinonasal large cell neuroendocrine carcinoma never have been reported in Korea. We experienced a case of primary large cell neuroendocrine carcinoma arising from left maxillary sinus recently. A 82-year-old male patient presented with nasal obstruction and epistaxis. The biopsy revealed large cell neuroendocrine carcinoma with poor differentiation. After a general evaluation, the patient was staged as cT3N0M0. The patient was treated by combined radiotherapy and chemotherapy. We report this rare case with literature review.

Objective: The aim of this study is to evaluate shoulder function and preoperative and postoperative electrophysiological changes related to the spinal accessory nerve with reference to neck dissection technique. Materials and Methods: We evaluated shoulder function by pain, strength and range of motion in a total of 35 neck dissection cases of 29 patients with head and neck cancer or thyroid papillary cancer. Electrophysiologic studies were performed before surgery, after third postoperative weeks and 6 months respectively. The results of each test according to the types of neck dissection were compared. Results: Clinical parameters of shoulder function and electrophysiologic study showed deterioration in early postoperative periods and improvements in late postoperative periods when the spinal accessory nerve was spared and permanent nerve damage was observed in radical neck dissection. There were correlations between the clinical parameters and electrophysiologic studies. Conclusion: The shoulder function after spinal accessory nerve sparing procedure is better than the function after nerve sacrificing procedure.

Metastatic tumors of the oral cavity are uncommon. Most of them are located in the mandible while only small percentage are found within the soft tissues. The common sites of metastases to the soft tissue of oral cavity were the tongue and gingiva and among the tongue, the base of tongue was most common. An explanation of the predilection may be due to a richer vascular supply within base of tongue. The authors have recently experienced a case of small cell lung carcinoma with base of tongue metastasis in a 81-year-old male who had foreign body sensation at swallowing and muffled voice for 2 months. So, we present this case with the review of literatures.
