Abstract
The objective of this study was to demonstrate the oncologic efficacy of awake endoscopic laryngeal surgery in the treatment of T1-T2 glottic carcinoma. This is a retrospective study. Seventy-one patients with early glottic carcinoma (T1a- 26, T1b- 18, T2- 27) who underwent awake flexible endoscopic laryngeal surgery under local anesthesia and mild intravenous sedation were included in the study. In 64 cases (90.1%) only endoscopic tumor ablation by Nd:YAG laser (in 32.4% of cases being preceded by diathermy snare excision) was performed, and in 7 T2 cases postoperative radiotherapy was also offered. There were no complications during or after the endoscopic surgery. Ultimate control of disease, including salvage treatment, was obtained in 67 patients (94.4%). Cure without recurrence was achieved in 60 cases (84.5%). Local control without salvage radiotherapy or/and open surgery was achieved in 64 (90.1%) patients. Larynx preservation was obtained in 66 (93.0%) cases. At 5 years from the beginning of endoscopic treatment, 74.6% of the patients were alive and free of disease. The best results were obtained in the T1a group of treated patients, all the patients being free of disease with the preserved larynx. Awake endoscopic laryngeal surgery is a safe and oncologically efficient method of treatment of early glottic carcinoma that can be considered as an alternative to the traditional approach, primarily, for patients with risks/contraindications for radiotherapy, general anesthesia, and transoral microsurgery, and also for the patients who prefer to avoid general anesthesia with its related risks and would rather choose office-based laryngeal surgery.

Abstract
OBJECTIVE Flexible endoscopic laser surgery (FELS) is able to overcome some limitations of traditional transoral CO2 laser surgery. The objective of this study was to assess the efficacy of FELS in the treatment of T1-T2 glottic carcinoma. METHODS We applied FELS for 120 patients with T1-T2 glottic carcinoma. Tumour ablation was performed with Nd:YAG laser. In 76 (63.3%) cases the intervention was performed under local anesthesia. Twenty nine (24.2%) patients (T1b - 2, T2-27) underwent postoperative radiation therapy (RT). RESULTS Successful treatment, with local control and larynx preservation, was obtained in 106 cases (88.3%), with mean follow-up of 6.4 years. More than 50% of the patients were followed-up over 5 years. CONCLUSIONS FELS can be proposed as an alternative treatment method for patients with early glottic carcinoma. The advantages of the method include: possibility of applying treatment under local anesthesia, that allows avoiding of general anesthesia and its related risks; applicability to patients with contraindications to general anesthesia and patients with anatomic particularities, that make transoral microsurgery impossible, allowing avoidance of the laryngofissure and tracheotomy.

Abstract
PURPOSE This study aimed at comparing phonatory outcomes between Trans-oral Laser Surgery and Radiotherapy in T1 glottic cancer. INTRODUCTION Early glottic carcinoma, i.e. T1 stage, can be treated using trans-oral surgery, radiotherapy, or partial open surgery. Trans-oral laser (TOL) surgical techniques and Radiotherapy (RT) have undergone significant advancement in the past few years leading to a decrease in open procedures. Various studies have been published comparing voice quality after TOL surgery and RT. There are few works which consider patients' opinions, i.e. subjective parameters regarding functional voice quality post treatment. This study uses both subjective and objective parameters to evaluate phonatory outcome of both treatment options. METHODS Phonatory outcomes were measured in patients who underwent RT and CO2 Laser excision for early laryngeal cancer. VHI, GRBAS and MDVP were used to measure the vocal outcome of treatment modality after 1 year of cancer-free survival. A comparison was then made between the outcomes in the two groups. RESULTS Superior vocal outcomes in G, R and S criteria of the GRBAS scale, a better VHI index, and better jitter, shimmer and NHR were found in patients who underwent CO2 laser excision as compared to patients who underwent RT. Other parameters were comparable between the two groups. CONCLUSIONS TOL surgery provides excellent vocal outcome as compared to RT in management of early glottic cancer and should be considered as the first line of management for the same.

Abstract
Aims and background To evaluate the effect of bcl-2 expression on the local control and overall survival of patients with early stage laryngeal cancer treated with radiotherapy alone. Methods and study design We included 53 patients with stage Tis, T1, and T2 laryngeal cancer who were irradiated in our department. Paraffin blocks of all biopsy specimens were subjected to immunohistochemical analysis with a bcl-2 oncoprotein mouse clone 124 Scytek kit. Results The mean follow-up time was 61 months (range, 7–166). Local-regional recurrence was observed in 10 (19%) patients. Forty-three patients (81%) had negative bcl-2 staining, 5 patients (9%) had + staining, 3 patients (6%) ++ staining, and 2 patients (4%) +++ staining. No relationship was detected between bcl-2 expression and local control or overall survival. The emergence of a recurrence and a younger age (<50 years) were significantly related to poor overall survival (P = 0.000 and P = 0.021, respectively). Patients with hemoglobin levels in the middle of radiotherapy and at the end of radiotherapy higher than 13 g/dl had improved overall survival in multivariate analyses (P = 0.002 and P = 0.001, respectively). Regarding local control, the following were poor prognostic factors: smoking more than 20 cigarettes a day (P = 0.001) and being younger than 50 years of age (P = 0.001). Conclusions No correlation was observed between bcl-2 expression and local control or overall survival. Whereas hemoglobin level, age and existence of a recurrence had a prognostic impact on overall survival, patient age and smoking status influenced local control rates.

Oncotarget 2017; 8:79761-79766. [PMID: 29108356 PMCID: PMC5668089 DOI: 10.18632/oncotarget.19337] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Accepted: 06/30/2017] [Indexed: 11/25/2022] Open
Abstract
Background Although the T3 category has been changed in the sixth edition of the TNM staging system proposed by the Union for International Cancer Control (UICC), the appropriate clinical target volume (CTV) of elective nodal irradiation (ENI) for T3N0 glottic carcinoma without cord fixation, which was formerly treated as a T1-2N0 disease, is not fully discussed. Materials and Methods We retrospectively analyzed 64 patients staged or restaged as T3N0 disease without cord fixation. All patients received irradiation to the primary lesion alone using opposed lateral fields. Surgery was performed in 10 patients without tumor regression after the delivery of 40 Gy. The other 54 patients received a median total dose of 66 Gy. Concurrent chemoradiotherapy (CRT) with low-dose cisplatin and UFT (low-dose CRT) and docetaxel, cisplatin, and 5-fluorouracil (TPF-CRT) were performed in 23 and 19 patients, respectively. Results Eighteen (28.1%) patients suffered treatment failure; all were recorded as local failure alone. The 5-year local control rates for RT alone, low-dose CRT, and TPF-CRT groups were 51.7%, 61.6%, and 93.8%, respectively (p = 0.027). The 5-year laryngeal preservation rates for RT alone, low-dose CRT, and TPF-CRT groups were 57.4%, 81.6%, and 89.5%, respectively (p = 0.048). Conclusions The rate of regional failure was zero when irradiating the primary lesion alone using opposed lateral fields. This treatment technique covers the most level III regions; hence, CTV for ENI should include level III alone.

Abstract
Glottic cancers discovered at an early stage (T1-T2) can be treated with either radiotherapy or surgery. The aim of our study is to analyse survival and functional results of supra-cricoid partial laryngectomy (SCPL) with crico-hyoido-epiglottopexy (CHEP) as surgical treatment for glottic carcinoma with anterior commissure involvement. We performed a retrospective study (1996-2013) which included patients who underwent SCPL-CHEP for glottic squamous cell carcinoma with involvement of the anterior commissure. Before surgery, all patients underwent staging including head, neck and chest CT-scan with contrast injection as well as suspension laryngoscopy under general anaesthesia. A total of 53 patients were included. The median follow-up period was 124 months. Tumour resection was complete in 96.2% of cases. The overall, specific and recurrence-free survival rates at 5 years were, respectively, 93.7%, 95.6% and 87.7%. The average period of hospitalisation was 18 days. The average time elapsed before decannulation and before restoration of oral feeding were 15 and 18 days, respectively. SCPL-CHEP is an important option for laryngeal surgical preservation. It allows adequate disease control as well as good functional results as long as the indications are well respected and the surgical techniques are mastered.

Abstract
Radiation effects on tissues greatly complicate reconstruction of head and neck defects. We discuss the unfavorable surgical conditions set up by prior surgery and radiation in patients undergoing salvage ablation of recurrent cancer. With the focus on vessel selection, flap donor site characteristics, and management of potential complications, we hope to highlight some of the lessons learned from these complex cases. Special attention is given to the topic of laryngopharyngeal reconstruction.

Abstract
To examine the usefulness and efficacy of administration of prostaglandin E1 (PGE1) after laryngeal surgery in patients who were previously treated with radiotherapy, we retrospectively examined the clinical data of 12 patients who had undergone partial laryngectomy and 21 patients who had undergone total laryngectomy. Complications were observed in 5 of the 7 cases treated with partial laryngectomy without PGE1 administration, while no complications were observed in the 5 cases treated with PGE1 after operation. Also, complications, including major leakage, were observed in 6 of the 15 patients who underwent total laryngectomy without PGE1, and no complications were observed in the 6 patients who received PGE1. The hospital stay was shorter for the patients treated with PGE1 than for those not receiving such treatment. Although this study was a small, nonrandomized pilot trial, the results indicated that PGE1 administration may be useful and effective for patients who undergo laryngeal surgery after irradiation failure, in decreasing the risk of postoperative complications and increasing the quality of life of the patients.

Abstract
This study is a retrospective analysis of 134 patients treated with radiotherapy at our hospital. The sample included 88 stage T1 and 46 stage T2 patients. Sixty-two patients had anterior commissure involvement, 37 patients had impaired vocal cord mobility, and 24 patients had supraglottic or subglottic extension. Irradiation was given, with the dose ranging from 60 to 72 Gy. Laryngectomy was the main salvage treatment for local recurrence. The 5-year initial and final local control rates were 71% and 83%, and the 10-year initial and final local control rates were 69% and 80%, comparable to the results of other series. The 5-year rate of overall survival with final larynx preservation was 77%. Multivariate analysis revealed that anterior commissure involvement is prognostic of a poor outcome in patients with T1 glottic cancer. Further subgroup analysis revealed that a fraction size of >200 cGy could overcome the negative impact of anterior commissure involvement and significantly improve the 5-year local control rate in T1 patients (100% at >200 cGy versus 45% at ≤200 cGy; p = .04). Subglottic extension of the glottic cancer predicted poor outcome in T2 patients. The 5-year local control rates of patients with and without subglottic extension were 9% and 77%, respectively (p < .001). According to our results, radiotherapy with a fraction size of >200 cGy is recommended for T1 disease with anterior commissure involvement. For patients with T2 disease and subglottic extension, radiotherapy alone produces poor results. Further improvement of outcomes by other treatment strategies needs to be investigated.

Abstract
AbstractBackground:Previous literature reviews comparing transoral laser surgery versus radiotherapy for glottic carcinoma treatment have analysed ‘early stage’ disease as one group. The current review aimed to assess local control outcomes, comparing these two treatment modalities, specifically for either tumour stage 1a or stage 1b lesions.Methods:The three authors conducted independent, structured literature searches. Simple weighted means were calculated.Results:Thirty-six publications were analysed. Three-year local control rates for tumour stage 1a tumours were 88.9 per cent for transoral laser surgery (n = 1308) and 89.3 per cent for radiotherapy (n = 2405). For tumour stage 1b tumours, the local control rates were 76.8 per cent for transoral laser surgery (n = 194) and 86.2 per cent for radiotherapy (n = 492).Conclusion:From this analysis of level four evidence, there was no demonstrable difference in local control rates for tumour stage 1a glottic squamous cell carcinoma treated by transoral laser surgery or radiotherapy. There was a trend towards improved local control of tumour stage 1b tumours treated with radiotherapy, but this finding was based on a limited number of published outcomes (n = 194).

Abstract
BACKGROUND The purpose of this study was to analyze voice quality among patients treated by definitive radiotherapy for laryngeal cancer. METHODS Ten patients with laryngeal cancer who had completed radiotherapy were involved in this pilot study. A standardized protocol was administered assessing: (1) sustained vowel production following maximal inspiration, (2) sustained vowel production for a 7-second duration repeated 5 times, and (3) spontaneous speech for 10 seconds. RESULTS The acoustic parameters among patients with early-stage cancer were not statistically different from healthy age-corresponding controls, except for shimmer (0.20 vs 0.16 dB, ρ = 0.01) and maximum phonation duration (24.37 vs 30.10 seconds, ρ = 0.04). For patients with locally advanced cancer, differences with controls were observed with shimmer (2.29 vs 0.16 dB, ρ = 0.01), jitter (7.49% vs 1.04%, ρ = 0.01), harmonics-to-noise ratio (2.67 vs 9.22, ρ = 0.01), and maximum phonation duration (14.12 vs 30.10 seconds, ρ = 0.01). CONCLUSIONS Despite the subtle differences in voice quality that existed, radiotherapy as a curative treatment for laryngeal cancer allows maintenance of a functional voice.

Abstract
BACKGROUND Laser surgery and radiotherapy are commonly used to treat glottic cancer. OBJECTIVE OF REVIEW To compare outcomes and cost of laser surgery versus radiotherapy for T1-T2N0 glottic cancer. TYPE OF REVIEW Meta-analysis. SEARCH STRATEGY The Cochrane Central Register of Controlled Trials, Ovid MEDLINE® In-Process & Other Non-Indexed Citations, Embase, Web of Science (1990-2010) were searched electronically. Three Chinese journals in otolaryngology were searched manually. EVALUATION METHOD Retrieved studies were analyzed with Review Manager 5.0 software. Methodological and outcome heterogeneity was analyzed using the χ(2) test and the I(2) test. Homogeneous and heterogeneous data were analyzed using a fixed random effect model. RESULTS Eleven studies involving 1,135 patients were included in the analysis. The cure rate did not differ between patients receiving laser surgery versus radiotherapy. Results on voice preservation were inconclusive. The overall cost for laser surgery was lower. CONCLUSIONS The quality of the reported clinical studies is limited. No level I data are available. Nonetheless, our analysis suggests that laser surgery and radiotherapy produce comparable outcomes.

Abstract
BACKGROUND AND PURPOSE In the majority of patients irradiated for early glottic cancer an abnormal voice was reported. The purpose of the study was to determine the factors influencing voice quality after radiotherapy for T1 glottic cancer. METHODS The voices of 75 male patients irradiated for T1 glottic carcinoma were assessed subjectively and objectively by acoustic analyses and aerodynamic measurements. The laryngeal function and morphology were evaluated by videolaryngostroboscopy. The data on smoking habits, the associated diseases influencing voice quality, the extent of the tumor, the type of biopsy, and the irradiation technique were collected from the medical records. The data on the factors influencing voice quality were compared for patients with a normal/near-normal voice and those with a hoarse voice. RESULTS Voice quality was at least slightly abnormal in 94.7% and 81.3% of patients, when assessed perceptively and objectively, respectively. Smoking after the completed treatment, more severe morphologic alterations of the vocal folds, dryness of the throat, incomplete closure of the vocal folds and functional voice disorders expressed as supraglottic activity adversely influenced the voice quality. A good correlation between the perceptive voice assessment and the acoustic analyses was established. CONCLUSIONS After the successful irradiation for T1 glottic carcinoma, the great majority of the patients have at least a slightly hoarse voice. A better voice outcome could be achieved if radiotherapy was followed by the patient's cessation of smoking and the appropriate voice therapy.

Abstract
We evaluated the radiation outcome and prognostic factors in a population-based study of early (T1N0M0) glottic carcinoma. Survival parameters and prognostic factors were evaluated by uni- and multivariate analysis in 316 consecutive irradiated patients with T1 glottic carcinoma in the Comprehensive Cancer Center West region of the western Netherlands. Median follow-up was 70 months (range 1-190 months). Five and ten-year local control was 86 and 84%. Disease specific survival was 97% at 5 and 10 years. In multivariate analysis, pre-existent laryngeal hypertrophic laryngitis was the only predictive factor for local control (relative risk = 3.0, P = 0.02). Comorbidity was prognostic for overall survival. No factor was predictive for disease specific survival. Pre-existent laryngeal hypertrophic laryngitis is a new risk factor associated with reduced local control in T1 glottic carcinoma treated with radiotherapy.

Abstract
OBJECTIVE To determine whether return of vocal cord function after treatment of T2b/T3 laryngeal carcinoma is an independent prognostic factor for locoregional recurrence. STUDY DESIGN A retrospective review of patients treated with radiation +/- chemotherapy between 2000 and 2005 for T2 with vocal cord paresis and T3 laryngeal carcinoma was conducted. METHODS Only those patients obtained from the tumor registry with pre-and posttreatment video stroboscopies were included. Patients' charts were reviewed for local and regional recurrence after treatment. Fisher's exact test was used to determine significant association between recurrence and possible risk factors. RESULTS Fourteen patients met the inclusion criterion. Six patients had T2 lesions with vocal cord paresis, and eight patients had T3 lesions. Fifty percent of patients with T2 and 75% of patients with T3 lesions had return of vocal cord function after treatment. Five of 14 patients did not have return of vocal cord function, and of these, 100% had locoregional recurrence. Of the nine patients who had return of vocal cord movement, none of the patients had recurrence. The proportion of recurrence was significantly higher for those whose vocal function did not return compared with the patients whose vocal function returned (100% vs. 0%, P < .01). CONCLUSION The immobile vocal cord is associated with a worse prognosis and is therefore factored into the American Joint Commission on Cancer staging for laryngeal tumors. We show that vocal cord immobility is an independent prognostic factor of recurrence even after treatment and can predict treatment failure in T2 and T3 lesions of the larynx.

Abstract
We analyzed the functional outcome and self-evaluation of the voice of patients with T1 glottic carcinoma treated with endoscopic laser surgery and radiotherapy. We performed an objective voice evaluation, as well as a physical, emotional and functional well being assessment of 19 patients treated with laser surgery and 18 patients treated with radiotherapy. Voice quality is affected both by surgery and radiotherapy. Voice parameters only show differences in the maximum phonation time between both treatments. Results in the Voice Handicap Index show that radiotherapy has less effect on patient voice quality perception. There is a reduced impact on the patient’s perception of voice quality after radiotherapy, despite there being no significant differences in vocal quality between radiotherapy and laser cordectomy.

Abstract
OBJECTIVES Several studies have explored posttreatment voice outcomes for early glottic cancer with varying results. To further clarify the voice-related quality of life (QOL) of T1 glottic cancer patients treated by external beam radiotherapy (EBRT) compared to endoscopic carbon dioxide laser excision (CLE), we performed a meta-analysis. METHODS We performed a meta-analysis review for the years 1966 to 2005 for the Voice Handicap Index (VHI), laryngeal cancer, voice outcome, voice quality, and quality of life. Studies in which the VHI was assessed at least 3 months after treatment for T1 glottic cancer were identified and analyzed by meta-analysis techniques. RESULTS Six studies with 208 patients (6 T1b and 202 T1a) treated with CLE and 91 patients (6 T1b and 85 T1a) treated with EBRT were identified. The posttreatment VHI scores were similar for the EBRT- and CLE-treated patients (p = .1, Wilcoxon rank sum test). CONCLUSIONS We conclude that CLE and EBRT provide comparable levels of voice handicap for patients with T1 glottic cancer.

Abstract
BACKGROUND Endoscopic laser resection is one treatment modality for early glottic carcinoma. Benefits are the preservation of laryngeal structure without tracheotomy, the short duration of treatment, low traumatisation and good functional results. METHODS From 1989 to 1999, 143 patients with an isolated and previously untreated glottic squamous cell carcinoma were treated by CO2 endoscopic laser resection. The tumors were classified as carcinoma in situ (Tis) in seven cases, T1 tumor (T1N0M0) in 91 patients and T2 tumor (T2N0M0) in 45 cases. Median follow-up was 5 years. RESULTS For the group of Tis and T1 carcinomas, 86 of 98 patients were free of recurrences. The 12 recurrences (12.2%) were treated by repeated laser surgery and laryngectomy (four patients). None of these patients died of tumor related causes. For patients with T2 carcinomas, the overall recurrence rate was 28.9% (13 patients). In six patients, a total laryngectomy had to be performed and one patient died because of tumor recurrence. The relapse free survival estimate using the Kaplan-Meier method was 87% for Tis and T1 carcinomas and 70% for T2 carcinomas. The overall laryngeal preservation rate was 95% for Tis and T1 carcinomas and 85% for T2 tumors. All recurrences occurred within 4 years of primary surgery. CONCLUSION The results suggest that the oncological outcome after endoscopic laser surgery is comparable to conventional open partial resections.

Abstract
The different types of small vocal fold tumor therapy allow the preservation of respiration and deglutition; the quality of phonation is the most important criterion for the patient. The aim of the study is to compare vocal function after treatment of T1a tumors by conventional and laser cordectomy. Fifty-seven male patients were included in the study: 27 underwent conventional cordectomy using an external approach, and 30 underwent an endoscopic microscopic laser cordectomy. Videolaryngoscopy was performed for each subject, and the maximal phonation time was measured. Spectrograms were recorded, and a perturbation analysis was performed if a clear harmonic structure was visible. Voices were perceptually rated by two experienced phoniatricians using the GRBAS scale. Even though a slightly better voice was found after conventional surgery throughout the data, no statistically significant difference was measured in the two groups. The data on voice outcome per se do not indicate the selection of one surgical approach over another.

Abstract
To evaluate the effectiveness of hyperfractionation for T2 glottic cancer from a viewpoint of laryngeal preservation, we analyzed 21 patients (twice-a-day group) who were treated with hyperfractionation between 1992 and 1998 and compared the results with those of 27 patients (once-a-day group) treated with conventional once-a-day radiation between 1987 and 1992. In the twice-a-day group, radiation was performed with two fractions of 1.2 Gy/day up to a total dose of 72-74.4 Gy. In the once-a-day group, radiation was performed with a fraction of 2 Gy/day up to a total dose of 66 Gy. If radiation was ineffective at 40 Gy, it was stopped, and surgical treatment was carried out. Kaplan-Meier estimates were used for the analysis of the survival rate and laryngeal preservation rate, and the results were compared. In the once-a-day group, the 5-year survival rate was 92.3%. The 5-year laryngeal preservation rate was 51.8%, and it was 60.3% in 20 patients who had undergone full-dose radiation (once-a-day full-dose group). In the twice-a-day group, no major complication, such as laryngeal necrosis, was seen in any case, and the 5-year survival rate was 95.3%. The 5-year laryngeal preservation rate was 95.3%, and it was significantly better than that of both the once-a-day group and the once-a-day full-dose group. Hyperfractionation is considered to be useful for preserving the larynx for the treatment of T2 glottic cancer.

Abstract
The purpose of this paper was to compare intensity-modulated radiation therapy (IMRT) and conventional planning for T2N0M0 squamous cell carcinoma (SQCC) of the glottic larynx. Three patients with T2N0M0 SQCC are presented who were treated with IMRT. Conventional plans were also generated for comparison purposes. Isodose distributions and dose-volume histograms (DVHs) were generated for all the plans to evaluate the fitness of the plan as well as the differential benefit of IMRT vs. conventional treatment. The isodose distributions that were obtained by the IMRT plan are much more conformal to the planning target volume (PTV) and clearly show that less healthy tissue is subjected to a high-dose level, thus reducing toxicity. IMRT offers better comformality without compromising the PTV coverage and delivers less dose to normal tissues as compared to conventional radiation therapy in T2N0M0 SQCC of the glottic larynx. With an increase in conformality, it is expected to have an increase in the therapeutic ratio.

Abstract
BACKGROUND Carcinoma of the larynx is the most common cancer affecting the head and neck region. In Northern Europe, early laryngeal cancer is almost universally treated by irradiation, but elsewhere it is treated by surgery. The main aim of this study was to determine whether there was any difference in survival between the two main therapeutic options. The secondary aim was to assess speech and voice quality in a small, randomized sample of patients from each treatment group. METHODS The subjects investigated were 488 patients with T1-2, N0 squamous cell carcinoma of the larynx. The patients form an unselected sequential group of our institution's experience with treating this disease over three decades. Four hundred nineteen patients were treated by irradiation, and 69 were treated with surgery. Most surgical patients were treated earlier in the series, whereas radiotherapy later became the treatment of choice. The primary outcome measures were recurrence at the primary site, recurrence in the neck, and tumor-specific survival. The secondary outcome measure was speech and voice quality. Statistical analysis was by univariate and multivariate analysis of association and survival. Surgery included horizontal or vertical partial laryngectomy and various minor procedures on the glottis, including cordectomy. Over a 30-year period, radiotherapy was administered to a dose of 60-66 Gy given over 30-33 daily fractions. RESULTS Surgery tended to be performed early on in the series and radiotherapy thereafter. Surgery was more likely to be carried out for supraglottic disease. These differences apart, the radiotherapy and surgery groups of patients were well matched. The 5-year tumor-specific survival for those treated by irradiation was 87% and for surgery it was 77% (p=.1022). Glottic cancer and T1 disease were associated with high 5-year survivals: 90% and 91%, respectively. Supraglottic site and T2 disease both had a poorer prognoses: 79% and 69%, respectively. The differences for both sets of data were significant. There was no significant difference in primary site recurrence rates for the two treatment modalities, but regional recurrence was higher in the surgery group. Further analysis demonstrated that this was not a function of surgery per se but rather of the unit's policy toward the N0 neck at the time surgery was carried out. Regarding speech and voice quality, radiotherapy was far superior to surgery. All patients in the radiotherapy group but only 3 of 10 in the surgery group were judged to have a good or normal voice (p=.0017). CONCLUSIONS Both surgery and irradiation are equally effective at treating early laryngeal carcinoma. Speech and voice were highly significantly better in patients treated by irradiation than in those treated by surgery.

Abstract
OBJECTIVE Early glottic carcinoma can be effectively treated with radiation or endoscopic laser surgery. We evaluated our experience treating early glottic cancer with laser CO2 surgery. MATERIAL AND METHODS 64 patients with Tis, T1 and T2 carcinoma, who underwent endoscopic CO2 laser excision between January 1999 and July 2002, were retrospectively analyzed. We performed an objective and subjective evaluation of speech, and evaluation of physical, emotional and functional well being. The mean follow-up was thirty months. RESULTS No patient died of this laryngeal neoplasm. Local control was achieved in 96% (62/64). Two patients with recurrence required total laryngectomy as savage treatment. Cause-specific survival was 100%, and overall survival was 98% (63/64). Voice quality was affected by laser surgery but impact on the quality of life was minor. CONCLUSIONS Laser cordectomy for treatment of early glottic cancer is a valid alternative to radiation, with good outcome for voice and minimum impact on quality of life.

OBJECTIVE To evaluate the results of radiotherapy in the treatment of patients with T1N0 glottic squamous cell carcinoma. MATERIAL AND METHODS Retrospective study of a cohort of 338 patients with T1N0 glottic carcinoma treated with radiotherapy at our institution between 1985-1997. A review of the literature published during the last ten years was carried out. RESULTS Local control with radiotherapy in our patients was 82%, reaching 97% when salvage surgery was included. The local control with radiotherapy in most of the published series ranges between 81.90%. CONCLUSIONS Treatment with radiotherapy achieves local control in early glottic carcinomas (T1N0) in 80-90% of cases. In our centre such treatment achieved local control in 82% of cases.

Abstract
OBJECTIVE AND STUDY DESIGN We designed a retrospective study to analyze treatment methods and outcomes for patients with lesions ranging from carcinoma in situ to invasive T1 glottic squamous cell carcinoma. Patients with nonsquamous cell carcinoma, verrucous variant of squamous cell carcinoma, anterior commissure involvement, and T2 lesions were excluded. SETTING University of Pittsburgh School of Medicine, a tertiary referral center. RESULTS Fifty-four patients met the inclusion criteria. Mean follow-up was 49 months (range 24 to 96 months). Forty-eight of 54 (89%) were treated with endoscopic excision. Forty of these 48 patients (83%) were successfully treated with endoscopic excision(s) as the only treatment modality. Four patients had persistence of disease despite multiple endoscopic excisions. Two of these patients underwent hemilaryngectomy, 1 received radiation treatment, and 1 received radiation therapy followed by a hemilaryngectomy. Four patients had recurrence of disease. Two patients with recurrence required radiation therapy and 2 patients required a total laryngectomy. With the selective application of multiple endoscopic excisions, radiation therapy, and more invasive operation, 100% of patients are without evidence of disease with a laryngeal preservation rate of 96%. CONCLUSIONS This study supports the use of endoscopic excisional biopsy as the primary treatment modality for lesions ranging from carcinoma in situ to invasive T1 glottic carcinoma. This study also highlights the importance of close clinical follow-up and the potential need for further treatment. By reserving open operation and radiation therapy to selective cases, we successfully treated all patients while limiting the disadvantages of radiation therapy and more invasive operation to the minority of patients.

Abstract
OBJECTIVES To define when laser resection of early-stage glottic carcinoma is indicated and to compare the results obtained by laser surgery with other therapeutic options. STUDY DESIGN Retrospective study of 151 patients treated from April 1982 to June 1996 in the Department of Otorhinolaryngology at "La Sapienza" University. We provide analysis of indications, techniques, and oncologic results of this study. METHODS Glottic tumors were treated with type III, type IV, and type Va cordectomies according to the classification of endoscopic cordectomies proposed by the European Laryngological Society in 2000. RESULTS The results are summarized as follows: all patients with carcinoma in situ Tis are free of disease with local control rate at 3 years of 100%; 2 died of other causes without evidence of local recurrence with an overall survival rate at 3 years of 83.2%. Of the 117 patients with stage T1a cancer, 110 are free of disease at 3 years with local control rate of 94%; 4 patients died of other causes without evidence of local recurrence with an overall survival rate of 96.5%. Of the 22 patients with stage T1b cancer, 20 are free of disease at 3 years with a local control rate of 91%; 1 patient died of other causes without evidence of local recurrence with an overall survival rate at 3 years of 95.4%. CONCLUSIONS According to our experience, we can conclude that endoscopic laser surgery is an efficacious and cost-effective treatment for early stage glottic cancer.

Abstract
PURPOSE Whereas there are many reports regarding treatment of early vocal cord cancer with cobalt 60 or 2-4-MV X-rays, there are still few reports on the results of treatment with 6-MV X-rays. Theoretically, 6-MV X-rays result in greater underdosage of tumor at the air-tissue interface and at the anterior commissure. This paper analyzes the results of irradiation of early and moderately advanced squamous cell carcinoma of the true vocal cord treated exclusively with 6-MV X-rays in a community hospital. The literature pertinent to the issue is reviewed. METHODS AND MATERIALS Eighty-three patients with Tis, T1, T2, or T3 squamous cell carcinoma of the true vocal cord were treated with curative intent at Bethesda Memorial Hospital in Boynton Beach, Florida between April 1986 and April 1998. The dose schedules most commonly used were 63 Gy in 28 fractions (2.25 Gy per fraction once a day) for T1 tumors or 74.40 Gy in 62 fractions (1.2 Gy per fraction twice a day) for T2 and T3 tumors. All patients have minimum 2-year follow-up; 63 (76%) have 5-year minimum follow-up. RESULTS Local control was achieved in 6 of 6 Tis, 53 of 54 (98%) T1, 8 of 8 T2, and 6 of 6 T3 lesions. No complications were encountered. CONCLUSIONS A recent literature review indicates that the treatment of early vocal cord cancer with 6-MV X-rays remains controversial. The dose schedules used in the present paper produced a high rate of local control, a finding that is consistent with reports of other investigators who used dose schedules similar to those used in the present series. However, several other investigators have reported significantly lower rates of local control for T1 or T2 glottic cancer treated with 6-MV X-rays when compared to results obtained with cobalt 60 or 4 MV at their own institution. The latter institutions used lower total doses and/or lower dose per fraction than those institutions reporting high rates of local control with 6 MV. Data from the literature, as well as our own data, are consistent with the following hypotheses: (1) the lower rates of local control reported by several institutions when using 6 MV compared with cobalt or 2-4 MV, using the same radiation dose schedules for each beam energy, indicate that underdosage of mucosal surfaces in the laryngeal air cavity may be a clinically important phenomenon, and (2) time-dose factors, although certainly important for lower energy beams, may be even more important when using 6 MV.

Abstract
OBJECTIVE To evaluate radiotherapy outcome and prognostic factors in early glottic carcinoma. METHODS The medical records of 76 patients with glottic T1N0 or T2N0 squamous cell carcinoma diagnosed at Tampere University Hospital from 1970 to 1991 and treated with primary radiotherapy were retrospectively reviewed. Except for three patients treated during the last years of the study period, radiotherapy was delivered by split-course technique with a pause of 1-3 weeks in the middle of the treatment. Primary locoregional control and disease-specific survival were analysed by the Kaplan-Meier method, and the log rank test was applied to compare the survival functions. Prognostic factors were evaluated by uni- and multivariate Cox regression analysis. RESULTS The 10-year locoregional control rate after radiotherapy was 83 and 48% for patients with T1 and T2 tumours, respectively (P = 0.0005). The 10-year disease-specific survival was 91% for T1 and 69% for T2 disease (P = 0.0018). The larynx could be preserved in 87% of T1 and 44% of T2 cases. Tumour extent expressed by the number of vocal cord thirds involved was the only factor with significant prognostic value in the multivariate analysis of primary locoregional control (hazard ratio (HR) 3.2, 95%CI 1.8-5.8, P = 0.0001). Involvement of the posterior vocal cord third (HR 8.4, 95%CI 1.0-69.5, P = 0.04899) and T-category (HR 3.0, 95% CI 0.9-10.2, P = 0.0790) were connected with poorer prognosis in the multivariate analysis of disease-specific survival. In the multivariate analysis of T1 cases only, higher number of vocal cord thirds involved (HR 5.9, 95%CI 2.2 16.2, P = 0.0005) and longer treatment duration (HR 1.1, 95%CI 1.0-1.3, P = 0.0188) indicated worse locoregional control. Treatment duration (HR 1.2, 95%CI 1.0-1.3, P = 0.0384) together with posterior cord involvement (HR 9.9, 95% CI 1.1-92.7, P= 0.0437) signified poorer survival. CONCLUSION Our findings indicate that the extent of the tumour is the most important predictor of radiotherapy outcome in early glottic carcinoma. This suggests that a classification based on the actual size of the tumour could be a better prognostic indicator than the conventional T-grouping. Although treatment duration was significant only in separate analysis of T1 cases, the split-course regimen resulting in long treatment times may be considered a major contributor to our relatively low local control rate also in T2 disease.

Abstract
From July 1975 to January 1998, 33 patients underwent partial laryngeal resection for residual or recurrent tumour after primary radical radiotherapy. Sixteen patients had T1 tumours on presentation, 14 were T2 and three were T3. Six patients underwent a supraglottic (horizontal) laryngectomy, 24 had a vertical partial laryngectomy, two had an endoscopic laser resection and one had an endoscopic laser resection followed by a vertical partial laryngectomy. The median time interval between radiotherapy and salvage surgery was 10 months (range 2-188 months). The median follow-up period was 41 months (range 12-185 months). There were five major postoperative complications (15%); two patients developed a pharyngeal fistula and three required further surgery for laryngo-tracheal stenosis. Twenty-five patients (76%) retained their larynx with satisfactory speech and swallowing. Eight patients (24%) had to be converted to a total laryngectomy, seven for recurrent disease and one for laryngeal stenosis. Of the eight patents converted, seven had normal swallowing and six developed good tracheo-oesophageal speech. Seven patients (21%) developed recurrent tumour after partial laryngectomy and were subjected to total laryngectomy; six of these seven were salvaged. Only one of the 33 patients died with recurrent tumour, giving an ultimate disease-related survival of 97%. Conservation laryngeal surgery for salvage of selected patients who fail radical radiation therapy is safe, effective, and results in reasonable preservation of laryngeal function.

Abstract
There is continuing controversy surrounding the most effective treatment of glottic carcinoma involving the anterior commissure (AC). Surgery has been the preferred method of treatment, since studies previously indicated early tumor invasion of the thyroid cartilage at the AC, thereby assuming less curability by radiotherapy (RT). Subsequent laryngeal anatomic studies and refinement of RT techniques have brought into question the ineffectiveness of curative irradiation. A retrospective review of 174 patients with early-stage glottic carcinoma treated with standard fractionation curative RT revealed 34 patients with T1 and T2 lesions involving the AC. Allowing for a follow-up of at least 3 years, we observed only a 12% (4 of 34 patients) local recurrence rate after RT alone, with excellent voice quality and no major complications related to the irradiation. The 4 local recurrences were controlled by total laryngectomy, although 2 patients developed distant metastatic disease. Radiotherapy represents an effective method of treating T1 squamous cell carcinoma of the glottis with AC involvement. The small number of T2 glottic carcinomas in this study prevents a meaningful conclusion concerning treatment of these lesions.

Abstract
Voice quality remains the issue often used to support preference for radiotherapy in treatment of early glottic cancer. We therefore conducted a perceptual voice study in 2 groups, one treated with radiotherapy for malignant disease and the other with narrow-margin laser cordectomy for either malignant or extensive benign lesions. Sequential patients, 12 treated with radiotherapy and 30 with CO(2) laser excision, were included. Voice samples were recorded before and at intervals after surgery. Ratings of validated judges were used for statistical analysis of various voice characteristics at each time point. Voice deteriorated temporarily after surgery as compared with the radiated group; however, at 6 and 24 months no significant differences were found between the groups. Preferential use of narrow-margin laser cordectomy for appropriate early glottic tumors can be supported not only for oncologic reasons but also on the basis of voice results, cost, and efficiency considerations.

Abstract
Near total laryngectomy with cricohyoepiglottopexy (CHEP) allows cure of glottic carcinomas with voice preservation. The subject of this study was to evaluate CHEP in terms of tumour control and functional result in T1 and T2 glottic carcinomas. This study reviewed retrospectively 55 consecutive cases of CHEP performed between January 1, 1981 and September 1, 1992 with the exclusion of post-radiotherapy salvage surgery. CHEP was indicated for a T1a limit to the anterior commissure and/or with dysplasia of the other vocal fold (10 cases), T1b (11 cases) and T2 (34 cases) glottic carcinomas. All our patients have a follow-up of more than five years. The post-operative course after this surgery was generally uneventful. The median time to decannulation was 18 days, to removal of the nasogastric tube was 15 days and to discharge from hospital was 23 days. No significant difference was observed according to the preservation of one or both arytenoid cartilages. The long-term functional result can be considered to be good in three-quarters of cases, with normal oral swallowing and an easily understood voice. The remaining one quarter had a whispery voice and sometimes episodes of aspiration when swallowing liquids. In terms of oncological results, the five-year recurrence-free survival rate was 94 per cent for T1 and 84 per cent for T2. The ultimate tumour control (taking into account four cases of total laryngectomy) was 94 per cent for T1 and 93 per cent for T2. Primary surgery by CHEP therefore appears to be a good option for early glottic carcinomas. The main problem remains that voice recovery is mediocre in one quarter of patients.

Abstract
BACKGROUND Standard treatment of early glottic carcinoma is radiotherapy, but involvement of the anterior commissure leads to a reduced cure rate. We investigated retrospectively whether our modified subtotal laryngectomy had improved results for early glottic carcinomas involving the anterior commissure, without causing excessive disability to laryngeal functions. METHODS Eighty-one patients with T1 or T2 glottic carcinoma involving the anterior commissure were reviewed. Follow-up was at least 3 years. Speech was assessed by subjective evaluation and a computer-assisted voice analysis device. RESULTS Three-year overall survival rate and 3- and 5-year actuarial survival rates were, respectively, 90.1%, 95%, and 90.8%, with no difference between the different T stages involved (p > 0.46). The local recurrence rate was 7.4%. Speech recovered in all patients and was evaluated as satisfactory in 86% of cases. CONCLUSION For early glottic carcinomas involving the anterior commissure, subtotal laryngectomies appear to be more effective than radiotherapy, and our modified technique simplifies the procedure.

Abstract
PURPOSE The aim of this study was to retrospectively compare the efficacy and functional results of three treatment options for T1N0M0 glottic carcinomas applied in a single institution. MATERIALS AND METHODS One hundred six charts of patients with biopsy-proven T1N0M0 glottic carcinomas treated between 1979 and 1995 were reviewed. There were 81 T1a and 25 T1b tumors. Forty-one patients were treated by radiotherapy (RT) (median dose of 64 Gy), 34 patients were treated by partial laryngectomy (PL) and 31 patients were treated by laser microsurgery (L) of which 10 received postoperative RT for positive margins. In 18 patients, a perceptual voice rating on a visual scale was performed by the patients themselves, three non-speech specialists and two speech therapists. RESULTS With a median follow-up time of 63.5 months, the 5- and 10-year loco-regional control probabilities reached 91 and 87%, respectively, without any difference between the treatment groups. After salvage laryngectomy, the 5- and 10-year loco-regional control probabilities reached 97% without any difference between the treatment groups. For the whole population, overall survival reached 78 and 62.4% at 5 and 10 years, respectively. The actuarial incidence of second primary reached 19% at 10 years. Regarding the quality of voice, overall there was a trend towards a worse satisfaction index, more hoarseness and more breathiness after PL than after L or RT. CONCLUSIONS Our data suggested that assuming proper selection of patients, RT and L yielded similar outcomes and functional results. Local recurrence can be adequately salvaged by surgery. On the other hand, PL appeared to yield similar loco-regional control probability but with a worse quality of voice.

Abstract
BACKGROUND AND PURPOSE Because opinions on the significance of repopulation during radiotherapy of T1 laryngeal cancer vary, we have estimated the effective rate of tumour cell repopulation during radiotherapy in patients with T1 laryngeal cancer. MATERIALS AND METHODS One hundred seventeen consecutive patients with T1 laryngeal cancer were treated from 1982 to 1993 by radical radiotherapy alone either as continuous (n = 28) or split-course treatment (n = 89). The logit method of the linear-quadratic formula for local control at 3 years was used to examine the effect of treatment time on local control. The analysis was made for all patients to obtain a wide range of overall treatment times. RESULTS The 3-year overall survival rate was 76% and the 3-year local control rate was 85% (range 82-88%). The local control rates were 95% (range 94-96%) for the continuous and 81% (range 75-91%) for the split-course therapy groups, respectively. The results showed a mean Dprolif value at the steepest part of the response versus time curve of 0.48 Gy/day for local control at 3 years although this was not statistically significant. The trade-off of dose required to compensate for a 1 week increase in treatment time for local control at the 90% level achieved at 3 years was calculated to be 3.5 Gy. CONCLUSIONS The present results suggest that repopulation should be taken into account even when treating small T1 laryngeal cancer and that protraction of the overall treatment time should be avoided.

Abstract
PURPOSE To evaluate the effect of tumor bulk in relation to various tumor-related prognostic factors and treatment-related variables on local control and survival of patients with T1 N0 M0 squamous cell carcinoma of the glottis. MATERIALS AND METHODS In 114 patients with T1 squamous cell carcinoma of the glottic larynx who were irradiated with curative intent, we determined the effect of tumor bulk in relation to mucosal extent (stage and anterior commissure involvement), histologic differentiation and various radiation factors, especially overall treatment time on local control and survival. Tumors were classified retrospectively as small surface lesions or bulky tumors. Seventy-seven patients had small lesions and 37 had bulky tumors. The anterior commissure was involved with cancer in 43 patients. The overall duration of irradiation ranged from 39 to 64 days. The median follow-up time was 6 years (range 5-24 years). RESULTS The 5-year actuarial local control rate for all patients was 82% after radiotherapy and 92% after salvage laryngectomy. On univariate analysis, bulky tumors and tumors involving the anterior commissure showed an adverse effect on local control, whereas the overall duration of irradiation had a borderline significance. The actuarial local control rate was 91% for small tumors and 58% for bulky tumors (P = 0.0002), 88% when the anterior commissure was not involved and 67% when the anterior commissure was involved (P = 0.01) and 89% when radiation was given in less than 50 days and 73% when irradiation exceeded 50 days (P = 0.06). On multivariate analysis. tumor bulk was the only significant factor that affected local control (P = 0.02). The 5-year actuarial survival for all patients was 73% and the disease-free survival was 92%. CONCLUSION This study shows that tumor bulk has a highly significant effect on the radiation control of T1 glottic cancer. Patients who had bulky tumors had lower local control and disease-free survival rates than those patients who had small tumors.

Abstract
PURPOSE At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. METHODS AND MATERIALS Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy. Before radiotherapy the patients were evaluated to determine the surgical procedure of choice. Either 66-68.4 Gy (33-38 fractions) or 63-65 Gy (28-29 fractions) of radiation therapy (RT) were administered. The overall disease free survival was determined for each subgroup of patients. Univariate and multivariate analyses were performed to determine significant prognostic variables. RESULTS Five- and 10-year overall survival rates were 83 and 72%, respectively. At a median follow-up of 6 years 204 patients are alive and disease free. No patient developed distant metastases. One patient died of a large local recurrence, 38 patients died of causes unrelated to their tumor, and 3 patients were lost to follow-up. The multivariate analysis confirmed that performance status (PS), macroscopic presentation of the lesion, and persistence of dysphonia after radiotherapy are significant prognostic factors. CONCLUSIONS According to the multivariate analysis, the patients with PS > 80 and with exophytic lesions are eligible for radical RT. The surgical procedure proposed for each patient was not found to be an independent prognostic factor.

Abstract
PURPOSE "Early" glottic squamous cell carcinoma classified as T1-T2N0 with anterior commissure invasion is conventionnaly managed with vertical partial laryngectomy (VPL) or radiation therapy (RT). At our insitution, in the early 1980s, vertical partial laryngectomy was progressively replaced by supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP). The medical files and operative charts of 62 patients with "early" glottic carcinoma classified as T1-T2N0 invading the anterior commissure, consecutively managed with cricohyoidoepiglottopexy, were retrospectively reviewed to ascertain whether any conclusions could be drawn regarding this treatment modality. MATERIALS AND METHODS Survival, local control, nodal recurrence, distant metastasis, and metachronous second primary tumor estimate was analyzed using the Kaplan-Meier life table method. RESULTS The 3- and 5-year actuarial survival estimate was 93.3% and 86.5%, respectively. The 3- and 5-year actuarial local control estimate was 98.2%. The only patient with local recurrence was successfully salvaged with RT resulting in an overall 100% local control rate and laryngeal preservation rate. The 3- and 5-year actuarial nodal recurrence estimate was 1.8%. The 3- and 5-year actuarial distant metastasis estimate was 0% and 2%, respectively. Aspiration related completion total laryngectomy and permanent tracheostomy never occurred. CONCLUSION The present retrospective study suggests that cricohyoidoepiglottopexy for glottic carcinoma classified as T1-T2 invading the anterior commissure resulted in higher local control rates and overall laryngeal preservation rate when compared with historical series using either VPL or RT. Further series are warranted to confirm our results.

Abstract
The objective of this study was to analyze the long-term results of laryngofissure with cordectomy for invasive glottic squamous cell carcinoma limited to the mid third of the mobile true vocal cord. The authors conducted a retrospective review of the medical charts and operative files of 33 patients with invasive glottic carcinoma limited to the mid third of the mobile true vocal cord managed with laryngofissure and cordectomy. A 10-year follow-up was achieved in 30 patients (90.9%). Kaplan-Meier actuarial analysis of survival, local control, nodal recurrence, distant metastasis, and second primary metachronous tumor was performed. The 5-year actuarial survival, local control, nodal recurrence, and distant metastasis estimates were 97%, 100%, 0%, and 0%, respectively. Tracheotomy was never performed. The overall laryngeal preservation rate was 100%. The 5- and 10-year actuarial metachronous second primary tumor estimates were 3% and 11.5%, respectively. The authors' experience suggested that laryngofissure and cordectomy should still be considered a valuable oncologic option for the management of invasive glottic carcinoma limited to the mid third of the mobile true vocal cord.

Abstract
BACKGROUND In order to evaluate whether individualized technique and dosimetry of radiotherapy increase local control, organ preservation, and survival of patients with T1 glottic cancer, we reviewed 76 cases treated from 1979 to 1993. METHODS Group A included 32 patients treated from 1979 to 1989 with different techniques, based on clinical aspects. Group B included 44 patients treated from 1990 to 1993 with individualized technique according to tumor extension and patient's anatomy. RESULTS Five-year local control with radiotherapy alone was achieved in 53% of group A versus 91% of group B (P > 0.005). Survival was similar in both groups with rescue surgery (90% versus 96%). Five-year survival with larynx preservation was 65% in group A versus 88% in group B (P = 0.02). Most recurrences (78%) appeared within 24 months of follow-up. CONCLUSION Adequate staging, individualized technique, computing planning using simulation and use of immobilization devices during cobalt-60 radiotherapy significantly increase local control and organ preservation in T1 glottic cancer.

Abstract
PURPOSE Treatment and disease-related factors were analyzed for their influence on the outcome of patients treated definitively with irradiation (RT) for early glottic carcinoma. METHODS AND MATERIALS One hundred two patients with stage T1 or T2 glottic carcinomas were treated definitively with RT from December 1983 through September 1993. Median follow-up time was 63 months. Factors analyzed for each patient included age, sex, stage, anterior commissure involvement, surgical alternative, histologic differentiation, field size, total dose, fraction size, and total treatment time. Survival analysis methods were employed to assess the effects of these factors on local control and complication rates. RESULTS The 5-year local control rates by stage were as follows: T1a, 92%; T1b, 80%; T2a, 94%; and T2b, 23%. By univariate analysis, factors found to have a significant impact on local control were stage, surgical alternative, fraction size, anterior commissure involvement, and overall treatment time. By multivariate analysis, stage, field size, and fraction size were the only significant factors that independently influenced local control. CONCLUSION The inferior control rate for stage T2b lesions has implications for treatment. Our study supports the conclusion of reports in the literature showing that low fraction size negatively influences outcome in patients with early glottic cancer.

Abstract
A retrospective analysis has been carried out of 4100 patients with pharyngolaryngeal carcinoma who were seen at the Hospital Gregorio Marañon between 1962 and 1993. 1287 patients were excluded from this study, leaving 2813 patients available for analysis. The great majority of the 2813 pharyngolaryngeal carcinomas were primary laryngeal tumours (2519). These are the subject of our study.We present our theoretic protocol for treatment of laryngeal carcinoma, both glottic and supraglottic, with special attention to the partial surgery. Our oncological and functional results are presented and discussed.

Abstract
There is a need for additional data in the literature regarding elective nodal irradiation in the treatment of T2N0 squamous cell carcinoma of the glottic larynx. We examined the experience at the Fox Chase Cancer Center and performed a literature review in order to define a treatment policy. Sixteen patients with T2 squamous cell carcinoma of the glottic larynx were treated with radiation therapy. Ten patients were irradiated to the larynx alone and six to the larynx and regional nodes. None of the patients in our series experienced a nodal recurrence regardless of whether the neck was electively irradiated. A literature review of 413 patients revealed that 2.6% of patients who did not have their nodes electively irradiated and had their primary tumor controlled experienced a nodal failure compared to 3.7% if the primary and regional nodes were irradiated (P = 0.88). Similarly, there was no significant difference in the rate of nodal failure for patients who experienced a recurrence at the primary site regardless of whether they received elective nodal irradiation (P = 0.36). We recommend treatment to the larynx alone since our policy is to treat the regional nodes only when the incidence of occult lymphadenopathy in the neck exceeds 15%.
