OBJECTIVE: To study clinical efficacy of surgery after the DCF induction chemotherapy in T2-3 laryngeal carcinoma and hypopharyngeal carcinoma. METHOD: To analyze clinical data about 102 cases of T2-3 laryngeal carcinoma and hypopharyngeal carcinoma retrospectively, 62 cases were divided into experimental group and 40 cases in control group, the experimental group completed three cycles of the DCF induction chemotherapy, then the efficacy was evaluated, surgery were carried out in the end, the control group received operation directly. In two groups, tumor response rates, toxicities, positive surgical margin rates and survival rate differences were observed and compared. RESULT: Tumor response rate was 61.3% in experimental group, the laryngeal carcinoma rate was significantly lower than that in hypopharyngeal (44.4% VS 84.6%, P < 0.05). Compared to its control, there were no significant differences about the positive surgical margin rate, the median survival time, 3-year and 5-year survival rate of laryngeal carcinoma(P > 0.05). The foci edges of 0. 3 cm and 0. 5 cm positive margin rate of hypopharyngeal carcinoma in experimental group were significantly lower than in its control (P < 0.05), but among the 1 cm edge' positive rate, the median survival time, 3-year and 5-year survival rate no significant differences were found (P > 0.05). During induction chemotherapy in the experimental group, no serious adverse reactions were found. CONCLUSION Induction chemotherapy of DCF regimen can not only narrow T2-3 laryngeal carcinoma and hypopharyngeal carcinoma' area, but also ensure an adequate safety margin.

Until the early 1990s, the standard treatment for locally advanced laryngeal cancer was total laryngectomy. During the past 20 years, effort was made to save the larynx by using chemotherapy combined with radiation and there has been significant progression in survival and the preservation of the function of larynx in recent days. Now, the standard treatment option for advanced laryngeal cancer is changing from radical surgery to induction or concurrent chemoradiation and the surgery is mainly reserved for salvage operation. But, the quality of life after CCRT is sometimes unacceptable due to severe side effects and some prefer function preserving surgery. The decision for surgical or nonsurgical options needs to be made according to patient's wishes and quality of life goals from a multidisciplinary approach with medical oncologists, radiation oncologists, and head and neck surgeons. Chemoradiation therapy allows for nonsurgical management, but judicious use is recommended because the surgical salvage for failure is much more complicated.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

OBJECTIVE: To study the efficacy of treatment with microsurgery in combination with local injection of type A botulinum toxin for vocal process granuloma. METHOD: 28 patients with vocal process granuloma received endotracheal intubation under general anesthesia. The lesion was removed with micro-scissor and CO2 laster under a self-retaining laryngoscope and microscope. The incision and mucous membrane surrounding the wound was closed with 8-0 absorbable suture. 4-point injection of botulinum toxin type A 8-15 u was then performed along the thyroarytenoid muscle and arytenoid muscle of the same side. Postoperative medication was administered based on disease causes. RESULT: All patients experienced vocal cord dyskinesia of the injected side 2-3 days after surgery. At 1 month after the surgery, wound healing was good in all the 28 patients, and the vocal cord movement was limited at the injected side. At 3 months, movement of the bilateral vocal cords was normal, and the vocal cord process mucosa was smooth. Patients were followed up for more than a year, and only one patient had recurrence in 2 months after surgery. The cure rate was 96. 4%. CONCLUSION Combination of laryngeal microsurgery and type A botulinum toxin local injection can shorten the treatment course of vocal process granuloma.

OBJECTIVE: To investigate the synergistic cytotoxicity of TRAIL and paclitaxel on laryngeal squamous carcinoma cell line Hep-2. METHOD: Hep-2 cells were exposed to various concentrations of TRAIL and paclitaxel respectively or jointly. The inhibition rate was measured by CCK-8 assay. The apoptosis rate and the expressions of DR4, DR5, DcR1 and DcR2 in Hep-2 cells were detected by flow cytometry methods. RESULT: Hep-2 cells were resistant to apoptosis induced by TRAIL. Paclitaxel could enhance its sensitivity to TRAIL by up-regulating the expressions of TRAIL death receptors in Hep-2 cells. CONCLUSION The resistance of Hep-2 cell to TRAIL could be overcome by paclitaxel. TRAIL and paclitaxel have synergistic killing effects on Hep-2 cells, so they might have a promising prospect in clinical therapy of laryngeal squamous carcinoma.

PURPOSE: In order to develop the national guide-lines for the standardization of radiotherapy we are planning to establish a web-based, on-line data-base system for laryngeal cancer. As a first step this study was performed to accumulate the basic clinical information of laryngeal cancer and to determine the items needed for the data-base system. MATERIALS AND METHODS: We analyzed the clinical data of patients who were treated under the diagnosis of laryngeal cancer from January 1998 through December 1999 in the South-west area of Korea. Eligibility criteria of the patients are as follows: 18 years or older, currently diagnosed with primary epithelial carcinoma of larynx, and no history of previous treatments for another cancers and the other laryngeal diseases. The items were developed and filled out by radiation oncologist who are members of Korean Southwest Radiation Oncology Group. SPSS v10.0 software was used for statistical analysis. RESULTS: Data of forty-five patients were collected. Age distribution of patients ranged from 28 to 88 years (median, 61). Laryngeal cancer occurred predominantly in males (10:1 sex ratio). Twenty-eight patients (62%) had primary cancers in the glottis and 17 (38%) in the supraglottis. Most of them were diagnosed pathologically as squamous cell carcinoma (44/45, 98%). Twenty-four of 28 glottic cancer patients (86%) had AJCC (American Joint Committee on Cancer) stage I/II, but 50% (8/16) had in supraglottic cancer patients (p=0.02). Most patients (89%) had the symptom of hoarseness. Indirect laryngoscopy was done in all patients and direct laryngoscopy was performed in 43 (98%) patients. Twenty-one of 28 (75%) glottic cancer cases and 6 of 17 (35%) supraglottic cancer cases were treated with radiation alone, respectively. The combined treatment of surgery and radiation was used in 5 (18%) glottic and 8 (47%) supraglottic patients. Chemotherapy and radiation was used in 2 (7%) glottic and 3 (18%) supraglottic patients. There was no statistically significant difference in the use of combined modality treatments between glottic and supraglottic cancers (p=0.20). In all patients, 6 MV X-ray was used with conventional fractionation. The fraction size was 2 Gy in 80% of glottic cancer patients compared with 1.8 Gy in 59% of the patients with supraglottic cancers. The mean total dose delivered to primary lesions were 65.98 Gy and 70.15 Gy in glottic and supraglottic patients treated, respectively, with radiation alone. Based on the collected data, 12 modules with 90 items were developed for the study of the patterns of care in laryngeal cancer. CONCLUSION: The study items for laryngeal cancer were developed. In the near future, a web system will be established based on the items investigated, and then a nation-wide analysis on laryngeal cancer will be processed for the standardization and optimization of radiotherapy.

Rhabdomyosarcoma is an uncommon type of soft tissue malignant neoplasm characterized by undifferentiated mesodermal tissue. Sarcomas account for approximately 1% of all laryngeal neoplasm and rhabdomyosarcomas are the rarest sarcoma found in the larynx. When the sarcoma involves the larynx, radical surgery such as laryngectomy has been considered. With recent advances of combined therapy, however, it can be treated by conservative surgeries followed by postoperative radiotherapy and/or pulse chemotherapy. With reviews of literature, we report a 47-year-old patient complaining of husky voice and throat discomfort who was finally diagnosed as rhabdomyosarcoma of the vocal fold and successfully treated by laser cordectomy followed by adjuvant chemoradiotherapy.
