JOURNAL FREE ACCESSWe reviewed 279 patients who received treatment for T3 and T4 laryngeal carcinomas at the Kurume University Hospital between 1979 and 2004. The purpose of this study was to clearly define histopathologic observation of the correlation between the cancer invasion into the laryngeal space and neck lymph node or distant metastasis. The analysis was also done using larynges from 128 patients who underwent total laryngectomy. In 80 supraglottic cancers, examined, preepiglottic space invasion was observed in 43 (54%), paraglottic space invasion was observed in 47 (59%) and cricoid area invasion was observed in 13 (16%). Pathologically, neck lymph node metastasis was observed in 39 (43%) of the 80. Distant metastasis was observed in 9 (12%) of the examined 74 cases. Preepiglottic space invasion strongly correlated with the cervical lymph node metastasis (p<0.01). Paraglottic space invasion correlated with the distant metastasis (p<0.05). Paraglottic space and cricoid area invasion strongly correlated with the distant metastasis (p<0.01). In addition, extraapsular spread correlated with the distant metastasis (p<0.05). These results indicate that neck dissection is necessary in cases with tumor invasion into the preepiglottic space. In cases with tumor invasion into the paraglottic space or extra - capsular spread, adjuvant chemotherapy should be considered. In 48 glottic cancers, preepiglottic space invasion was observed in 2 (4%), paraglottic space invasion was observed in 36 (75%), cricoid area invasion was observed in 18 (39%). Pathologically, neck lymph node metastasis was observed in 12 (25%) of the 48. Distant metastasis was observed in 9 (20%) of the examined 45 cases. Paraglottic space invasion strongly correlated with the cervical lymph node metastasis (p<0.05). Cricoid area invasion strongly correlated with the cervical lymph node metastasis (p<0.05). There was no statistically significant correlation between the carcinoma extension into the laryngeal space and distant metastasis. There was no statistically significant correlation between extra-capsular spread and distant metastasis.View full abstractDownload PDF (14547K) -

JOURNAL FREE ACCESSSCL-CHEP is originally designed to treat T2 glottic cancers. Extended resection including ipsilateral arytenoid and paraglottic space might be employed to treat selected T3 and T4 cancers. However, arytenoid fixation and subglottic invasion involving cricoid cartilage are considered contraindication for this surgery. We reviewed the clinical data of the 14 patients with T3 or T4 cancers who received SCL-CCHEP over last 9 years. Most of the T3 cases obtained satisfactory laryngeal functions. Among the two T4 cases, one case had swallowing difficulty because of the removal of the posterior part of cricoid cartilage. The patient received total laryngectomy 30 months after SCLCHEP procedure. It is crucial to properly evaluate the extent of the tumor when considering SCLCHEP for advanced laryngeal cancers. A thorough informed consent is also necessary to facilitate the success of the organ preservation treatment.View full abstractDownload PDF (6203K) -

JOURNAL FREE ACCESSWe treated 23 (1.4% of all our primary cases) younger patients who are from 15 years old to 29 years old with head and neck malignancies at the Department of Head and Neck Surgery of the Miyagi Cancer Center Hospital for the past 12 years. There were 12 male and 11 female, and the sex ratio was approximately 1: 1. There were 12 oral cancer patients, 6 epipharyngeal cancer patients and so on. There were 14 squamous cell carcinomas, 3 nasopharyngeal carcinomas and so on. 60% of all cases were squamous cell carcinomas. Clinically, advanced stage (stage III and IV) was diagnosed in 70% of patients at presentation. Although 19 patients had no past history, 2 patients had bronchial asthma, one had schizophrenia, and one had psychological disorder. Radical treatment was performed in 20 of 23 examples. The estimated Kaplan-Meier 5-year cause-specific survival rates for all patients were 76% and the 10-year cause-specific survival rates were 63%, respectively. It was thought that survival consequence was excellent in the whole. The problems of head and neck tumor treatment in a younger patient were thought about with late effect by radioactive rays and genital disorder by cancer chemotherapy.View full abstractDownload PDF (12375K) -

JOURNAL FREE ACCESSThirty-seven patients with nasal cavity or paranasal sinus cancer received superselective intra-arterial infusion therapy of cisplatin and conventional concomitant extrabeam radiotherapy (RADPLAT). Five-year progression free rate of primary lesion and overall survival were 84% and 73% for all patients, respectively. Acute toxic effects were considered acceptable, however, severe toxic events occurred in some cases, namely, eye problems, tearing, obstructive sinusitis, osteoradionecrosis, and so on. We considered these complications did not severe compared with those of surgery. RADPLAT is considered to be one of the treatments for nasal cavity and paranasal sinus cancer.View full abstractDownload PDF (11093K) -

JOURNAL FREE ACCESSWe performed 37 cases of maxillary cancer ablation from October 2001 until June 2005. Among them, 28 cases were immediately reconstructed using free flaps, and in 9 cases prostheses were used for maxillary defects. Reconstruction methods were rectus abdomisis musclocutanous flap in 27 cases and fibula osteocutaneous flap in 1 case. In the 28 reconstruction cases, there were complications in 12 cases, and there were major complications requireing additional salvage surgeries occurred in 3 cases. Because of the conservative treatment, even ruptured sutures in the oral cavity did not prolong fasting in the reconstruction cases during the postoperative period. The time until oral intake following operation in the reconstruction cases averaged 15.0 days, against 14.3 days in prostheses cases. There was not statistically significant association between them.View full abstractDownload PDF (6483K) -

JOURNAL FREE ACCESSWe retrospectively examined our instisution's skull base surgery for malignant paranasal sinus tumor (except esthesioneuroblastoma) from 1999 to 2005. During this time, 95 patients with sinonasal tumor were treated. Eighteen (patients with esthesioneuroblastoma were excluded) of these underwent a skull base sugery. The median age was 57 years (range, 2-73 years). The median followup period was 29 months. Factors such as dural invasion, extent of skull base, orbital apex involement (especially squamous cell carcinoma) may have an effect on tumor recurrence. In our hospital, the indication of the skull base surgery for malignant paranasal sinus tumor is dural invasion, infratemporal fossa involvement, pterygopalarine involvement, intraorbital involvement, orbital apex involvement. The contraindication is brain invasion, cavernous sinus invasion, carotid canal involvement, orbital apex involvement (squamous cell carcinoma), sphenoid sinus involvement, distant metastasis, histologic findings (melanoma and undifferenciated carcinoma).View full abstractDownload PDF (14740K) -
