The aim of the study is to assess voice quality after treatment. We also evaluated local recurrence, overall survival, disease free survival and toxicity. Material and Methods: We examined a total of 36 patients, out of which 27 were smokers: 10 females/5 smokers;26 males/22 smokers. The sample was observed from January 2007 to July 2012 (average follow-up period: 33.5 months, range 12 - 76). Diagnosis of early glottic carcinoma was eight during the two-year period 2007/2008, nine during 2009/2010, eleven during year 2011 and eight during year 2012. All patients suffering from early glottic carcinoma, histopathologically confirmed, were classified as follows: 24 patients T1a, 3 patients T1b, 6 patients T2 and 3 patients had a carcinoma in situ. They were treated only with conventional radiotherapy. After the treatment (total dose 70 Gy), patients were asked to fill out the Voice Handicap Index (VHI) questionnaire, composed of 30 questions that covered physical, emotional and functional areas. Results: The global VHI was evidenced with good voice quality (62% of patients: VHI < 30;34% of patients: VHI 31 - 60). Vocal disability was mild in over 70% of patients within the physical area and over 80% within the emotional area. We observed two local recurrences, one occurred five years after the end of radiation therapy and one six months after. In terms of toxicity, we observed that acute reactions, such as dysphonia, dysphagia and erythema, were relatively limited. Conclusions: The VHI index suggests that radiotherapy produces acceptable functional results, with limited repercussion on life quality. In line with literature, our data confirmed good cure rates and larynx preservation (94.4%).展开更多

A retrospective analysis was conducted of 35 cases of T2N0M0 glottic carcinoma. Fourteen patients with normal vocal cord mobility were treated with endoscopic CO2 laser surgery alone. The remaining 21 patients were treated with CO2 laser surgery followed by radiotherapy (44 - 70 Gy, including low-dose carboplatin chemoradiotherapy). Main outcome measures were local control, organ preservation, recurrence, 5-year survival, and successful salvage in cases of recurrence. We evaluated the patient’s voice with the psychoacoustics GRBAS scale, maximum phonation time (MPT), and airflow rate (AFR) obtained by aerodynamic tests. Mean follow-up period was 5 years. Among the 35 T2N0M0 patients, 5-year survival and 5-year voice preservation rates were 97% and 89%, respectively. Local recurrence occurred in 7 of these patients (20%);4 of 7 local recurrences were successfully re-treated by laser surgery. Total laryngectomy was necessary for salvage treatment in the remaining 3 patients. The post-treatment voice qualities were judged to be the same or improved over pretreatment qualities. There was little change in MPT and AFR after treatment in non-recurrence patients. CO2 laser microsurgery is an excellent tool for treating selected cases of T2N0M0展开更多

However, the best treatment is still controversial due to lack of randomized controlled trials. We aimed to evaluate the treatment results and the prognostic factors of local control of early glottic squamous cell carcinoma patients (GSCC) T1-2N0M0 treated at our institution. Material and Methods: We retrospectively studied the charts of 52 patients with early GSCC T1-T2N0M0 from 2010-2015 at the Clinical Oncology Department, Ain-Shams University. 24 patients had T1 and 28 had T2 early glottic carcinoma. The overall survival OS, local control rate, and laryngeal preservation rate were evaluated. Kaplan-Meier method, Cox proportional hazards model were used to analyze the data. Results: Median duration of follow-up was 13 months. Thirty-eight patients received radiation treatment alone (73.1%), 7.7% of the patients underwent surgery alone, and 19.2% of the patients had surgery combined with radiotherapy. Local recurrence after radiation failure developed in 6/52 patients, all had T2 disease and were salvaged by total laryngectomy. The ultimate local control rate was 88.5%, and the ultimate laryngeal preservation rate was 77.2% (40/52 patients). The median OS of the 52 patients was 13 months (range 2 - 46 months). Univariate analysis of factors associated with poor local control showed that age > 60 years was the only significant factor (P = 0.048). Conclusion: Radiotherapy achieves high local control and laryngeal preservation rates for patients with early glottic carcinoma, and is associated with a low rate of severe complications compared to surgery. Salvage surgery is feasible after radiotherapy failure.展开更多
