Abstract
OBJECTIVE The purpose of the study was to assess whether partial cordectomy or complete cordectomy with narrow free margins is a safe oncological procedure for T1 glottic carcinoma. We also studied surgical margins and the involvement of anterior commissure. METHODS Thirty-one T1 glottic carcinomas underwent endoscopic CO(2) laser excision of the lesion based on the depth of infiltration by the tumor with 1-2mm free margins. If detecting free margins was not macroscopically possible, additional biopsies along all the uncertain margins of the excision's residual area were taken. After excision, the specimen was mounted on a plastic support, flattened and then held in place with fine needles. It was then oriented and mapped. The pathologist measured the lesion's point of maximum infiltration and its distance from the free margins. RESULTS Local and ultimate control at 36 months was 95% and 100%, respectively. We performed 29 partial and two complete cordectomies. Complete resection of the lesion was obtained in 90.4% of the cases. Re-resection was necessary in 9.6% of the cases due to positive margins. The anterior commissure was affected in 38.7% of the cases, and was the site of maximum infiltration in 9.6% of the cases. The mean maximum infiltration was 0.93mm in the anterior commissure, 2.18mm in the anterior 1/3rd of the vocal cord, 1.71mm in the middle 1/3rd of the vocal cord and 1.5mm in the posterior 1/3rd of the vocal cord. In 83.9% of the cases (p<0.01), the anterior 1/3rd of the vocal cord was the section most frequently involved. In 19 patients (61.3%) (p<0.01), the anterior 1/3rd of the vocal cord was also the area with the highest incidence of maximum infiltration by the tumor. CONCLUSION We concluded that.

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
BACKGROUND Laser cordectomy is gaining popularity for treatment of early glottic carcinoma, but little is known about vocal and quality of life (QOL) outcomes as a function of extent of resection. We prospectively examined QOL and vocal function of patients with carcinoma in situ (Tis) or T1 glottic carcinomas after laser cordectomy. METHODS Patients (n = 75) were grouped into those who underwent unilateral subepithelial or subligamental resection (group A, n = 45); those who underwent unilateral transmuscular or total cordectomy (group B, n = 17); and those who underwent extended or bilateral cordectomy including the anterior commissure (group C, n = 19). The European Organization for Research and Treatment of Cancer head and neck cancer specific module (QLQ-H&N35), voice handicap index (VHI), and objective vocal function were examined before and 1 year after cordectomy and compared among the groups. RESULTS No major complications were encountered, but local recurrence occurred in 10 patients, with group C showing the highest rate (6/19, 31.6%). Patient-reported speech and social contact scores of QOL questionnaire and VHI scores after surgery were higher in groups B and C than in group A (p < .05). The scores and perceptual and acoustic data were generally improved in all groups after surgery, but were statistically significant only in group A (p < .03). CONCLUSION Our data suggest that early glottic cancers with a limited extent and infiltration depth have improved outcomes, both oncologically and functionally, compared to those lesions requiring extensive laser resection.

Abstract
In the treatment of early-stage glottic cancers, radiotherapy and surgery have similar success rates. In our department, we have been using cold instruments coupled with surgical microscope and/or telescopes for several years in treatment of early stage glottic cancers. Our aims were, to present our experience with endolaryngeal resection of T1 glottic cancers with cold instruments coupled with surgical microscope and telescopes, to present our oncological results, to discuss the advantages of endolaryngeal cordectomy over open cordectomy or RT and to discuss whether laser is obligatory for this approach or not. Our study includes retrospective analysis of 38 patients with T1 glottic cancer, who have been treated with endolaryngeal surgery as the primary treatment. The median follow-up was 24 months. The most commonly performed procedure was type-II cordectomy (38.5%). Overall survival rate was 94.7%, while the disease-specific survival rate was 100%. Local recurrences occurred in two patients at 8th and 11th months, postoperatively. In the first patient, type-Vc cordectomy and in the second type-Va cordectomy had been performed. Both patients with recurrences could be salvaged by fronto-lateral laryngectomy, and are still alive in their 38th and 6th months following salvage surgery. Therefore, the local control rate and larynx preservation rate with endolaryngeal cordectomy were 94.7 and 100%, respectively, in this study group. All patients had a voice quality sufficient for communicating easily over telephone. We believe that lasers are not obligatory to perform endolaryngeal cordectomy for treatment of T1 glottic cancers, as the same oncological and similar functional outcomes may be achieved with the traditional cold instruments.

Abstract
Aim To evaluate voice outcomes in patients with early glottic carcinoma treated by CO2 laser cordectomy. Method 15 patients with glottic Tis and T1 squamous cell carcinoma treated with CO2 laser were analyzed. The assessment consisted of perceptual voice analysis, objective voice evaluation and video-laryngo-stroboscopic exam. In addition, patients rated their voices and completed the Voice related Quality of Life (VR-QOL) questionnaire. The results were compared with those obtained in a matched control group. Results Most of the patients presented some degree of hoarseness on perceptual voice analysis, mainly rough and breathy voices. Their acoustic evaluation compared with the control group showed a small increase in fundamental frequency, but with no statistically significant difference, and the values of jitter, shimmer and noise to harmonic ratio were worse and statistically significant. As regards to video-laryngo-stroboscopic findings, better results were achieved in the less extensive resection group. Patients have had minimal repercussion in their life quality in respect to voice. Conclusions: In spite of voice alterations in patients submitted to cordectomy by CO2 laser, functional results are acceptable, with minimal repercussion in their quality of life.

Abstract
BACKGROUND Endoscopic management of laryngeal carcinoma has gained popularity among laryngologists based on the good oncologic and functional results. We evaluated the voice quality after laser cordectomy for early glottic cancer in a variety of vocal situations and its relation with the extension of resection and the age. METHODS We conducted a cross-sectional study of voice quality in 42 consecutive male patients treated for T1 glottic carcinoma with laser cordectomy. Patients were compared with 21 controls. Voice quality was self-assessed by the patients. Perceptual analysis was done by a speech pathologist on a running speech sample [GRBAS (grade, roughness, breathiness, asthenicity, strain)]. Acoustic analysis included fundamental frequency (F0), jitter, shimmer, noise to harmonic ratio (N/H), and maximum phonation time (MPT) on the sustained vowels /a/ and /i/, and on various running speech voice samples. RESULTS Distribution of the patients included in the study by T classification was as follows: Tis, n = 2 (4.8%); T1a, n = 35 (83.3%); and T1b, n = 5 (11.9%). Cordectomy types were: (I), 14%; (II), 26%; (III), 21%; and (V), 38%. Voice improved in almost 60% of patients, returning to normal in 45%. GRBAS showed significant differences between patients and controls and correlated with type of cordectomy. Acoustic analysis showed significant differences in F0, and jitter, with smaller differences in shimmer, N/H, and MPT. CONCLUSION Voice quality after laser cordectomy differs from controls, but improves in a majority of patients after the surgery, with almost 50% of patients with subjective normal or near normal voice. Voice quality depends on type of 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 Treatment of early glottic malignancies is controversial, particularly if postoperative endoscopy shows minimal/no residual disease. METHODS In a prospective nonrandomized study, we performed endoscopic laser surgery with curative intent in 59 patients with early glottic carcinoma presenting for radiotherapy after diagnosis elsewhere by random biopsy or cordal stripping. We analyzed outcomes and residual cancer in the specimen. RESULTS Clinical staging elsewhere did not correspond to (usually underestimated) the pathologic stage in 60.7%. In 22%, no tumor was identified on pathologic examination. After 35.3 months (mean), 93.2% were alive with no evidence of disease. Local control was achieved in 98.3% of the patients, and 13.5% of the patients required radiotherapy. The larynx was conserved in 98.3%. CONCLUSIONS Biopsy/stripping are best abandoned for persistent glottic lesions. A single laser endoscopic procedure provides reliable staging and definitive treatment in most cases using fewer resources. Biopsied patients presenting for treatment should be offered laser surgery as an alternative to radiotherapy.

Abstract
OBJECTIVES To understand the effect of adjuvant cryotherapy on glottic wound healing after endoscopic CO2 laser cordectomy. STUDY DESIGN Canine acute injury model with videolaryngostroboscopic and histopathologic outcomes analysis. METHODS Twelve adult male dogs underwent bilateral endoscopic CO2 laser transmuscular cordectomy followed by randomized unilateral endoscopic glottic cryotherapy. The animals were randomly divided into four groups and underwent videolaryngostroboscopy followed by sacrifice at 0, 2, 6, and 12 weeks postoperatively. Three untreated male dogs served as controls. Histopathologic sections were prepared with Alcian blue, Giemsa, hematoxylin-eosin, movat's, Masson's trichrome, and picrosirius stains. RESULTS Videostroboscopy demonstrated an earlier restoration of glottic volume and a return of mucosal waves among vocal folds treated with combined therapy by 6 weeks posttreatment. The mean depth of inflammatory reaction in the vocal cords treated with combined therapy was 1.07 mm versus 1.15 mm in vocal cords treated with CO2 laser therapy alone. At 2 and 6 weeks postoperatively, combined treatment was associated with a decreased volume of collagen. At 12 weeks postoperatively, combined treatment was associated with greater collagen organization, normalized collagen histoarchitecture, and decreased keratinization. CONCLUSIONS Adjuvant cryotherapy appears to alter glottis-specific wound healing, leading to decreased and more organized collagen formation and decreased keratinization with a resultant improvement in glottic function, when compared with CO2 laser surgery alone, in an acute canine injury model. Studies in humans are ongoing to further evaluate the clinical potential of cryotherapy on glottic wound healing.

Abstract
Purpose To develop a clinical practice guideline for treatment of laryngeal cancer with the intent of preserving the larynx (either the organ itself or its function). This guideline is intended for use by oncologists in the care of patients outside of clinical trials. Methods A multidisciplinary Expert Panel determined the clinical management questions to be addressed and reviewed the literature available through November 2005, with emphasis given to randomized controlled trials of site-specific disease. Survival, rate of larynx preservation, and toxicities were the principal outcomes assessed. The guideline underwent internal review and approval by the Panel, as well as external review by additional experts, members of the American Society of Clinical Oncology (ASCO) Health Services Committee, and the ASCO Board of Directors. Results Evidence supports the use of larynx-preservation approaches for appropriately selected patients without a compromise in survival; however, no larynx-preservation approach offers a survival advantage compared with total laryngectomy and adjuvant therapy with rehabilitation as indicated. Recommendations All patients with T1 or T2 laryngeal cancer, with rare exception, should be treated initially with intent to preserve the larynx. For most patients with T3 or T4 disease without tumor invasion through cartilage into soft tissues, a larynx-preservation approach is an appropriate, standard treatment option, and concurrent chemoradiotherapy therapy is the most widely applicable approach. To ensure an optimum outcome, special expertise and a multidisciplinary team are necessary, and the team should fully discuss with the patient the advantages and disadvantages of larynx-preservation options compared with treatments that include total laryngectomy.

Abstract
BACKGROUND After treatment for early glottic carcinoma, a considerable number of patients end up with voice problems that interfere with daily life activities. The objective of this randomized and controlled study was to assess the efficacy of voice therapy in these patients. METHODS Of 177 patients, 6-120 months after treatment for early glottic carcinoma, 70 patients (40%) suffered from voice impairment based on a 5-item screening questionnaire. Approximately 60% of those 70 patients were not interested in participating in the current study. Twenty-three patients who were willing to participate were assigned randomly either to a voice therapy group (n = 12 patients) or to a control group (n = 11 patients). Multidimensional voice analyses (the self-reported Voice Handicap Index [VHI], acoustic and perceptual voice quality analysis, videolaryngostroboscopy, and the Voice Range Profile) were conducted twice: before and after voice therapy or with 3 months in between for the control group. RESULTS Statistical analyses of the difference in scores (postmeasurement minus premeasurement) showed significant voice improvement after voice therapy on the total VHI score, percent jitter, and noise-to-harmonics ratio in the voice signal and on the perceptual rating of vocal fry. CONCLUSIONS Voice therapy proved to be effective in patients who had voice problems after treatment for early glottic carcinoma. Improvement not only was noticed by the patients (VHI) but also was confirmed by objective voice parameters.

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
PURPOSE After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice. METHODS AND MATERIALS The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer. RESULTS Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery. CONCLUSIONS The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer.

Abstract
PURPOSE OF REVIEW To evaluate the optimal treatment of early laryngeal cancer and to highlight new developments. RECENT FINDINGS The use of hyperfractionation and acceleration of radiotherapy may result in improved outcomes for patients with respect to cancer cure and preservation of the larynx. Options for surgical treatment include endoscopic resection and open partial laryngectomy. The use of endoscopic vertical partial laryngectomy may overcome the difficulties encountered in exposure with transoral laser resection of anterior commissure tumors. The microdebrider may be a useful alternative to CO(2) laser in endoscopic resection in selected cases. A further treatment option that shows promising results is photodynamic therapy, which has some important advantages over the other treatment modalities. Further larger studies are needed to assess the efficacy of these treatment modalities to ascertain the treatment modality of choice. SUMMARY Different treatment modalities are available for early laryngeal cancer. The treatment choice should take into account the likely post-treatment morbidity, quality of life, patient preference, and voice quality. The cost of treatment, not only to the treating institution but also to the patient and those involved in the patient's care at home, is also an important issue. Well-designed randomized multicenter controlled trials are now necessary to influence patients' and clinicians' decision in the choice of the most effective and predictable treatment plan.

Abstract
OBJECTIVES To assess whether proposed voice and quality of life (QoL) outcome measures were likely to be acceptable to patients previously treated for early glottic cancer by either radiotherapy or endoscopic resection, as well as looking for differences in QoL and voice between treatments. DESIGN Questionnaire-based cohort study. SETTING Secondary care, three centres. PARTICIPANTS All patients treated for T1a or in situ glottic carcinoma between 1997 and 2003. Fifty-three patients were identified; those who had undergone salvage surgery or radiotherapy were excluded. A proportion refused to participate or could not be contacted and two patients had died of unrelated causes. Thirty-six patients completed the trial with 18 from each treatment arm. MAIN OUTCOME MEASURES Quality of voice as assessed by three questionnaires, Voice Handicap Index (VHI), Vocal Performance Questionnaire (VPQ), Voice Symptom Score (VoiSS) and perceptual analysis of voice by Grade, Roughness, Breathiness, Asthenia and Strained (GRBAS) assessment of vocal recordings. Quality of life as assessed by the Hospital Anxiety and Depression Scale (HADS), University of Washington Quality of Life Questionnaire (UW-QoL), and the Functional Assessment of Cancer Therapy (FACT) questionnaire. RESULTS All patients included in the trial were able to complete the questionnaires; however, 19% required assistance of some kind. GRBAS assessment showed no difference between groups for any criteria. All QoL questionnaires gave equivalent good scores. All of the voice questionnaires showed no statistical difference between groups except for the emotional subscale of the VoiSS which showed a significantly better score for the radiotherapy arm (P = 0.04). CONCLUSION All outcome measures were applicable and acceptable to the patient group. Overall QoL and voice appears similar despite treatment arm, apart from the emotional subscale of the VoiSS. A randomized controlled trial is required to further assess this question.

[PMID: 15890067 PMCID: PMC1142310 DOI: 10.1186/1472-6815-5-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/28/2004] [Accepted: 05/12/2005] [Indexed: 11/10/2022]
Abstract
BACKGROUND: In this study, we aim to gather information about the quality of life issues, functional outcomes and voice problems facing early glottic cancer patients treated with the surgical techniques such as laryngofissure cordectomy, fronto-lateral laryngectomy, or cricohyoidopexi. In particular, consistency of life and voice quality issues with the laryngeal tissue excised during surgery is examined. In addition, the effects of arytenoidectomy to the life and voice quality are also studied. METHODS: 29 male patients were enrolled voluntarily in the study. The average age was 53.9 years. Three out of 10 patients with laryngofissure cordectomy also had arytenoidectomy. 11 patients had fronto-lateral laryngectomy with Tucker reconstruction, two of which also had arytenoidectomy. There were eight patients with cricohyoidopexi and bilateral functional neck dissection. Three of these patients also had arytenoidectomy. In bilateral functional neck dissection cases, spinal accessory nerve was preserved and level V of the neck was not dissected. None of the patients had neither radiotherapy nor voice therapy. Cordectomy patients never had a temporary tracheotomy or were connected to a feeding tube. Data was collected for 13 months for the cordectomy group, 14 months for fronto-lateral laryngectomy and cricohyoidopexi groups on average post-operatively. Statistical analysis in this study was carried out using the one-way analysis of variance, and the Post-Hoc group comparisons were made after Bonferroni and Scheffe-procedures.In order to determine the effects of arytenoidectomy, a regression analysis is carried out to see if there are statistical differences in answers given to the survey questions among patients who were arytenoidectomized during their surgeries. RESULTS: There was a statistically significant difference between cordectomy and cricohyoidopexi group in answers to the University of Washington- Quality of Life- Revised survey part 1. (p = 0). A statistically significant difference was also established between cordectomy and fronto-lateral laryngectomy groups, as well as between cordectomy and cricohyoidopexi groups in answers to the University of Washington- Quality of Life- Revised survey part 2. (p = 0,036 and p = 0.009, respectively). Cricohyoidopexi group has given the lowest scores and the cordectomy group has given the highest scores in three survey questions representing the quality of life, performances and new voices. These ranges are also consistent with the laryngeal tissue excised during surgery (cricohyoidopexi > fronto-lateral laryngectomy > cordectomy). There was no statistically significant difference between groups in Performance Status Scale for Head and Neck cancer patients instrument. The difference between the Voice Handicap Index and Voice Handicap Index (functional); Voice Handicap Index (physical) and Voice Handicap Index (emotional) scores in three patient groups was not significant either. All of the patients evaluated that their new voices have similar functional, physical and emotional impact on their life. Decanulation and oral feeding times of cricohyoidopexi and fronto-lateral laryngectomy patients are found to be significantly longer than cordectomy patients. Lastly, the removal of arytenoid does not have any significant adverse effects on the quality of life, the functional outcomes, or the quality of voice. CONCLUSION: In the present study, all patients with early glottic cancer, treated with different surgical technics reported fairly good quality of life outcomes, functional results and voice qualities. This study also finds that the removal of arytenoid does not have any adverse effects on the quality of life and voice from the patients' point of view.

Abstract
OBJECTIVE In treating early glottic carcinomas, the outcomes of endoscopic laser cordectomy have been proven to be valuable in local control, survival, and vocal function preservation. In some extended cases, however, laser cordectomy may leave patients with poor vocal function because of vocal fold deficit. This work assesses the vocal outcome of medialization laryngoplasty with bipedicled strap muscle transposition for vocal fold deficit resulting from laser cordectomy in early glottic cancer patients. STUDY DESIGN A prospective clinical series. METHODS Thirteen early glottic cancer patients who had vocal fold deficit caused by previous laser cordectomy underwent medialization laryngoplasty with bipedicled strap muscle transposition. The thyroid lamina on the cordectomy side was paramedially separated. The inner perichondrium was circumspectly raised from the overlying thyroid cartilage. After separating the thyrohyoid and cricothyroid membranes, the lamina was retracted laterally. A bipedicled strap muscle flap was then transposed into the area between the lamina and the paraglottic soft tissue. The thyroid cartilages were carefully sutured back in position. All patients received pre- and postoperative voice assessments comprising laryngostroboscopy and vocal function studies. RESULTS Vocal enhancement was present in 92% (12/13) of patients after medialization laryngoplasty with strap muscle transposition. The glottal closure and maximal phonation time were noticeably improved by surgery. No dyspnea or other significant complications were observed in any patients. CONCLUSION The outcomes show that bipedicled strap muscle transposition is a prosthesis-free, safe, and valuable laryngoplastic technique for correcting glottal incompetence caused by endoscopic laser cordectomy in early glottic cancer patients.

Abstract
OBJECTIVES To calculate recurrence, mortality and complication rates and evaluate postoperative voice quality after laser resection of T(1a) glottic carcinoma. MATERIAL AND METHODS Since 1995 we have treated 118 patients with a T(1a) glottic carcinoma with laser surgery. In order to evaluate postoperative voice quality, patients who were alive and free of recurrence were sent the Voice Handicap Index (VHI) questionnaire containing 30 questions concerning how their voice affects their daily life physically, emotionally and socially. RESULTS Twelve patients (10%) had a local recurrence and received further treatment, either a second laser treatment, radiotherapy or a total laryngectomy. One patient (0.84%) died due to the laryngeal cancer. Ninety-nine patients were sent the VHI questionnaire and 94 of the completed questionnaires were included in the study and analyzed. The mean total score was 13.2, with mean subscores of 6.5 (physical), 4.1 (functional) and 2.5 (emotional). CONCLUSIONS The results indicate that these patients as a group do not consider that their voice has a negative impact on their daily life. Good surgical technique is essential to obtain a good functional result. The laser strength should be kept low and the surgical margins small in order to minimize scarring and vocal cord stiffness.

Abstract
T1-T2 glottic carcinomas may be treated with conservative surgery or radiotherapy. The goals of treatment are cure and laryngeal voice preservation. The aim of the current study was to review the pertinent literature and discuss the optimal management of early-stage laryngeal carcinoma. Literature review indicated that the local control, laryngeal preservation, and survival rates of patients were similar after transoral laser resection, open partial laryngectomy, and radiotherapy. Voice quality depended on the extent of resection for patients undergoing surgery; results for patients undergoing laser resection for limited lesions were comparable to the corresponding results for patients receiving radiotherapy, whereas open partial laryngectomy yielded poorer results. Costs were similar for laser resection and radiotherapy, but open partial laryngectomy was more expensive. Patients with well defined lesions suitable for transoral laser excision with a good functional outcome were treated with either laser or radiotherapy. The remaining patients were optimally treated with radiotherapy. Open partial laryngectomy was reserved for patients with locally recurrent tumors.

Abstract
Radiotherapy as well as endoscopic laser surgery as the most widely used treatment modalities for T1a glottic carcinoma cause minor morbidity and negligible mortality and result in more or less comparable, excellent cure and larynx preservation rates. Therefore, other outcome measures such as voice-related problems and health status are important factors in the choice of treatment for T1a glottic cancer. The present study focuses on voice-related problems in the daily life of patients treated by radiotherapy or endoscopic laser surgery for T1a glottic cancer. Self ratings on health status assessed by means of COOP/WONCA health status charts and voice problems evaluated with a validated voice-specific questionnaire (the Voice Handicap Index) and overall judgment on voice quality were obtained. A total of 102 patients (56 treated by endoscopic laser surgery and 46 treated by radiotherapy) with at least 1-year follow-up were included. Response scores were high: 52 (93%) patients after endoscopic laser surgery versus 40 (87%) patients after radiation therapy completed and returned the questionnaires. A high percentage of patients reported voice problems in daily life: 58% of the patients following radiotherapy and 40% of the patients following endoscopic treatment had abnormal VHI scores. The difference between both treatment modalities proved to be significant. No significant differences were found concerning health status or overall judgment of voice quality. Moderate correlations were found between total VHI score and voice quality judgment and the COOP/WONCA social activities chart. This study reveals that treatment for T1a glottic cancer often does result in voice problems in daily life, negatively influencing patients social activities. Patients selected for endoscopic laser surgery on average report fewer voice-related problems than those who underwent radiotherapy.

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
Radiotherapy contends with endoscopic surgery for the role of treatment of choice for Tis-T1 glottic cancer. The amount of vocal cord to be surgically removed logically depends on the surface and deep extension of the neoplasm. Thus, a prerequisite for proper management includes an analysis of the voice changes after each of the progressive types of cordectomy described in the European Laryngological Society Classification. Between January 1998 and December 2000, 89 patients with glottic cancer (8 Tis, 63 T1a, 18 T1b) underwent different types of endoscopic cordectomy. Perceptual analysis (GRBAS scale); objective analyses of jitter, shimmer, and noise-to-harmonics ratio; and subjective (Voice Handicap Index) evaluation of voice were performed in 51 patients. Statistical evaluation of preoperative and postoperative objective results by analysis of covariance, as well as perceptual and subjective data, showed significant voice improvement after type I and II cordectomies, with the voice attaining nearly normal parameters. By contrast, after type III, IV, and V cordectomies, the vocal outcome was not significantly different from the preoperative pattern. It can therefore be concluded that type I and II resections, whenever indicated, are adequate procedures even for professional voice users. By contrast, accurate counseling is mandatory before type III, IV, and V cordectomies.

Abstract
OBJECTIVE To share the authors' experience of transoral laser microresection in the treatment of squamous cell carcinoma of the anterior commissure of the larynx. STUDY DESIGN Retrospective review of 39 patients with squamous carcinoma involving the anterior commissure of the larynx, all managed with transoral laser microresection between September 1996 and December 2001. Twenty-three patients had pT1 or pT2 cancers. Sixteen patients had pT3 or pT4 disease, two with N2b neck metastases. Twenty patients had cancers exhibiting spread to the subglottis. Twenty-five patients had received prior treatment(s). METHODS Specific data points entered into a portable database were retrospectively verified against the patient's electronic medical record. Sorting and analysis were completed in a desktop spreadsheet. We evaluated tumor recurrence, cause of death, tracheostomy, hospital length of stay, and voice quality. RESULTS None of the 17 patients with early cancers (pT1 or pT2a) had local recurrence, and none received postoperative radiotherapy. Five of the 22 patients with intermediate or advanced disease (pT2b/pT3 or pT4 cancer) required second treatments for persistent or recurrent disease. Of these, two had small residual foci amenable to second-stage resection by laser. One patient developed a prelaryngeal soft tissue recurrence and retained his larynx after wide local excision and radiotherapy. Two patients (both previously irradiated) developed delayed recurrences requiring total laryngectomy. Four retreated patients remained alive without disease. One patient died of other causes. Voice remained no worse after transoral laser microresection in 19 patients. It was one level worse (on a scale of 0 to 5) for 16 patients. Eleven patients received temporary tracheotomies, some for airway, some for exposure. Twelve patients left the hospital on a same-day basis. The average hospital stay was 3.3 days. CONCLUSION Transoral laser microsurgery is one of the options to be considered for the treatment of squamous cell cancer involving the anterior commissure of the larynx.

Abstract
OBJECTIVE To describe preliminary voice, speech, and swallowing outcomes in patients treated by endoscopic laser excision of laryngeal cancer with or without adjuvant radiation therapy. STUDY DESIGN Retrospective review. METHODS Seventeen surgically treated patients (five T2 glottic and 12 clinically staged T2 supraglottic squamous cell carcinomas) participated in the study. Self-ratings of voice (Voice Handicap Index) and swallowing (M. D. Anderson Dysphagia Inventory) were completed, as well as independent auditory-perceptual ratings of voice and speech recordings. RESULTS Although no significant difference between Voice Handicap Index, M. D. Anderson Dysphagia Inventory, and listener ratings was identified based on tumor site and irradiation status, there was a trend toward poorer outcomes in patients who received adjuvant radiation therapy. Whereas the patients having supraglottic cancer tended to report better voice but poorer swallowing outcomes, the glottic cancer group displayed the opposite pattern. Severity on Voice Handicap Index correlated significantly with listener severity ratings of speech, suggesting that the patients' perception of their voice handicap was similar to the listeners' judgments of their speech severity. CONCLUSIONS The results suggest the following trends: 1) Adjuvant radiation therapy was associated with poorer outcomes for voice, speech, and swallowing and may be associated with more impairment than surgery alone and 2) poorer outcomes on voice and swallowing were observed for the glottic and supraglottic cancer groups, respectively. To bolster these preliminary findings, additional outcomes studies in patients treated with conservation therapy are needed.

Abstract
OBJECTIVE To compare the effect on phonation of radiotherapy and endoscopic laser surgery for stage T1a glottic squamous cell carcinoma. STUDY DESIGN Retrospective. METHODS Patients treated for stage T1a glottic carcinoma from August 1994 to March 2000 and who had been followed for at least 1 year were candidates. Eight patients who underwent radiotherapy and 22 who underwent laser surgery were enrolled. Indirect laryngoscopy and stroboscopic examination were performed, and voice quality was analyzed using standard parameters. RESULTS Maximum phonation time, average airflow rate, sound pressure level, and average fundamental frequency during unconditional phonation were similar after laser surgery and radiotherapy. However, compared with normal men who were 50 years of age or older, the average fundamental frequency was higher after laser surgery. CONCLUSIONS Contrary to some reports, the voice quality is minimally affected by laser surgery for T1a glottic carcinoma, and outcome is similar to radiotherapy. The average fundamental frequency is higher than normal after laser surgery, but the effect on the quality of life was trivial.

Abstract
OBJECTIVE To analyze quality of life, functional outcome, and hidden costs by primary treatment with surgery or radiation therapy in patients with early glottic cancer. STUDY DESIGN Retrospective study in a tertiary care facility. METHODS A group of 101 patients with carcinoma in situ and T1 invasive squamous cell carcinoma treated primarily with either surgery or radiation, between January 1990 and December 2000, were identified from searching our tumor registry. Patients completed two previously validated questionnaires and one local questionnaire. Statistical significance was assessed with the rank sum test, chi2 test, or Fisher's Exact test. RESULTS Questionnaires were completed in 59% (44 of 74) of the surgical cohort and 41% (11 of 27) of the radiation therapy cohort. The primary surgical treatments were endoscopic excision (86%), hemilaryngectomy (12%), and total laryngectomy (1%). Patient-reported problems with swallowing, chewing, speech, taste, saliva, pain, activity, recreation, and appearance showed no difference between the endoscopic excision or radiation therapy cohorts. Comparing endoscopic excision versus radiation therapy, respectively, median number of treatments (2 vs. 35), total median travel distance (150 vs. 660 miles), total median travel time (180 vs. 1440 min), and total median number of hours of work missed (76 vs. 24) all differed significantly (P <.01). CONCLUSIONS Almost all patients with early glottic cancer, whether treated with surgery or radiation therapy, reported excellent quality of life outcomes and functional results. In addition to actual costs, the hidden costs for radiation therapy versus endoscopic excision were all greater in terms of total number of hours of work missed, total travel time, and total travel distance.

Abstract
Phonosurgical management of early glottic cancer has evolved considerably, but objective vocal outcome data are sparse. A prospective clinical trial was done on 32 patients with unilateral cancer (T1a in 28 and T2a in 4) who underwent ultranarrow-margin resection; 15 had resection superficial to the vocal ligament, and 17 deep to it. The subepithelial infusion technique facilitated selection of these patients for the appropriate procedure. All are cancer-free without radiotherapy or open surgery. Involvement of the anterior commissure (22/32) or the vocal process (15/32) of the arytenoid cartilage did not influence local control. Nine of 17 patients had resection of paraglottic musculature, and all underwent medialization reconstruction by lipoinjection and/or Gore-Tex laryngoplasty. Eight of the 17 had resections deep to the vocal ligament, but without vocalis muscle, and 1 of the 8 underwent medialization. Posttreatment vocal function measures were obtained for all patients. A clear majority of the patients displayed normal values for average fundamental frequency (72%) during connected speech, and normal noise-to-harmonics ratio (75%) and average glottal airflow (91%) measures during sustained vowels. Smaller majorities of patients displayed normal values for average sound pressure level (SPL; 59%) during connected speech and for maximum ranges for fundamental frequency (56%) and SPL (59%). Fewer than half of the patients displayed normal values for sustained vowel measures of jitter (45%), shimmer (22%), and maximum phonation time (34%). Almost all patients had elevated subglottal pressures and reduced values for the ratio of SPL to subglottal pressure (vocal efficiency). There were significant improvements in a majority of patients for most vocal function measures after medialization reconstruction. Normal or near-normal conversation-level voices were achieved in most cases, regardless of the disease depth, by utilization of a spectrum of resection and reconstruction options. These favorable results are based on establishing aerodynamic glottal competency and preserving the layered microstructure of noncancerous glottal tissue.

Abstract
This article reviews management of early laryngeal squamous cell carcinoma with respect to current standards of practice and recent advances in minimally invasive endoscopic surgery, specifically highlighting powered instrumentation as an alternative to transoral laser resection of early glottic lesions. Limitations of the current staging system, controversy regarding management of lesions involving the anterior commissure, and the role of radiation therapy versus surgical management are also discussed with reference to current outcomes literature.

Abstract
As the trend in laryngeal cancer treatment shifts towards organ-conservation surgeries and organ-preservation protocols, patients will more often retain anatomy vital to communication and swallowing. Despite a conservative approach, results of treatment may have debilitating effects. Rehabilitation efforts are directed towards a return to functional, if not normal, status. Although there are predictable trends in voice and swallowing disorders of patients with laryngeal cancer, posttreatment dysphonia and dysphagia are diverse in presentation. Considering the significant diversity of this population, speech pathologists should work closely with otolaryngologists to determine the most appropriate treatment for each patient. As this article demonstrates, voice and swallowing therapy are necessary components of the rehabilitation process following treatment for head and neck cancers. As always, treatment is tailored to the specific individual and based on information obtained during a thorough evaluation by a speech pathologist. Fortunately, with the help of voice and swallowing therapy, many patients return to functional communication and oral feeding.

Abstract
Transoral laser surgery today is the mainstay of treatment for T1 and T2 glottic carcinoma. The vocal ability remains sufficient in the majority of patients. However, in some cases, a significant glottic gap may persist, leading to poor voice quality. We report a special technique of medialization thyroplasty using autologous cartilage specifically adapted for vocal rehabilitation after laser resection. Six patients with a significant glottic gap following laser surgery were treated. For vocal rehabilitation, a special medialization technique was performed. The superior rim of the thyroid cartilage of the resected side was exposed. A 1 x 2-cm piece of cartilage was harvested and reimplanted into a subperichondrial pouch created on the inner side of the thyroid cartilage. When phonation was optimal, this cartilaginous strut was sutured and/or glued in place. In all 6 cases, the vocal function improved significantly. The dysphonia index (0 = normal, 3 = aphonia), which includes objective parameters as well as expert voice ratings and the patient's perception, increased by 1.1 on average (range, 0.4 to 1.6). The results have been lasting. The established medialization techniques are of limited value in a larynx scarred by laser surgery. Injection augmentation is often futile because the tight scar tissue does not lend itself to augmentation. Implantation of nonorganic material may cause problems if revision surgery for tumor recurrence should become necessary or if the implant protrudes into the scarred endolarynx. The technique reported avoids these pitfalls and leads to voice quality improvement comparable to that of established medialization procedures.

Abstract
For early-stage laryngeal cancer, both surgery and radiotherapy are effective treatment modalities, offering a high rate of local control and cure for this select group of patients. The probability of obtaining local control for early glottic cancer is similar when comparing the results of radiation therapy, cordectomy, and hemilaryngectomy. Radiation therapy has been the treatment of choice for all previously untreated T1 and T2 vocal cord cancers at our institution. We currently treat most patients with irradiation and consider transoral laser excision for the small subset of patients with well-defined T1 tumors that are limited to the mid-third of the cord. In this area, excision will not significantly diminish voice quality. Stage I and stage II supraglottic cancers may be treated with either radiation therapy alone or with a supraglottic laryngectomy with bilateral selective neck dissections (levels II-IV). In experienced hands, transoral laser excision also is an acceptable alternative for selected lesions. Overall, approximately 80% of patients at our institution are treated initially by irradiation.

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
BACKGROUND Radiotherapy, open surgery and endolaryngeal excision (with or without laser) are all accepted modalities of treatment for early stage glottic cancer. Case series suggest that they confer similar survival advantage. Opinions on optimal therapy vary across disciplines and between countries. OBJECTIVES To compare the effectiveness of open surgery, endolaryngeal excision (with or without laser) and radiotherapy in the management of early glottic laryngeal cancer SEARCH STRATEGY Electronic search of MEDLINE (from 1966 to October 2000), EMBASE (from 1980 to October 2000), CINAHL (from 1982 to October 2000) and CancerLit (from 1963 to October 2000) databases and the Cochrane Controlled Trials Register. SELECTION CRITERIA Randomised controlled trials (RCT) comparing open surgery, endolaryngeal resection and/or radiotherapy DATA COLLECTION AND ANALYSIS Two reviewers independently assessed RCTs identified from the electronic searches for eligibility and methodological quality. All authors of the review discussed the results of these assessments. MAIN RESULTS Only one RCT was identified which compared open surgery and radiotherapy among a substantial number of patients with early glottic laryngeal cancer. REVIEWER'S CONCLUSIONS There is currently insufficient evidence to guide management decisions on the most effective treatment. Interpretation of the only large scale RCT comparing open surgery and radiotherapy in patients with early glottic cancer is limited because of concerns about the adequacy of treatment regimens and deficiencies in the reporting of the study design and analysis. Endolaryngeal resection of early glottic tumours is becoming more common and a well designed multicentre RCT is warranted.

Abstract
BACKGROUND Both surgery and radiotherapy are recognized treatments of T1-T2 squamous cell carcinoma of the larynx. We retrospectively analyze and compare the oncological outcome of patients treated in a single institution, either by endoscopic surgery or partial supracricoid laryngectomy versus radiation therapy. METHODS The medical records of 156 patients treated between 1983 and 1996 with either surgery (n = 75) or radiotherapy (n = 81) were reviewed. Male to female ratio, median age, and T-stage distribution were comparable. RESULTS With a median follow-up time of 59 months, the 5-year cause-specific survival rate of 93% was identical for both groups. The actuarial incidence of metachronous second primaries was 7% at 5 years. Local control at 5 years remained 84% after surgery and 77% after radiotherapy. Anterior commissure infiltration was shown to represent a negative predictive factor of local control for radiotherapy (p =.01). Salvage treatment brought ultimate local control to 96% of patients after surgery and 94% after radiation therapy with long-term laryngeal preservation rate altered significantly (p =.05) in the group of patients who received radiotherapy (90.1% vs 97.4%). CONCLUSION The treatment of laryngeal cancer is always a compromise between oncological efficiency and preservation of function. Our data suggest that, assuming proper selection of patients, radiation therapy and surgery yield similar local control and survival rates. The functional disadvantages after surgery are moderate and clearly counterbalanced by a significant decrease in long-term laryngeal preservation rate after radiotherapeutic treatment.

Abstract
A prospective randomized study was designed to compare phonatory mechanisms in patients treated with frontolateral partial laryngectomy (FLPL) with or without glottic reconstruction with false vocal fold (FVF) mucosal flap. Objective voice assessment was based on computerized acoustic recordings and videolaryngostroboscopy performed before, 1 year after, and 2 years after surgery. Phonatory mechanisms were studied according to the surgical technique and correlated with acoustic recordings. The results showed that supraglottic structures participated in laryngeal closure and voice production in 80% of cases in which a standard FLPL was performed. The FVF mucosal flap was involved in both laryngeal closure and voice production in 54% of patients treated with glottic reconstruction. The type of laryngeal closure (glottic or supraglottic) statistically influenced the acoustic measurements. As glottic closure is more frequent in patients treated with glottic reconstruction, the authors recommend performing reconstruction of the glottis with an FVF mucosal flap when an FLPL is indicated.

Abstract
A cohort of 88 patients with glottic cancer (13 Tis, 75 T1) who underwent endoscopic CO2 laser excision between January 1995 and June 1997 was prospectively studied. The mean follow-up was 43 months (range, 30 to 60 months). The depth and extent of the excision (graded according to the European Laryngological Society Classification, which includes 5 types of resection) were based on the results of a preoperative and intraoperative diagnostic test battery. Five patients died of other diseases, and none of glottic cancer. Of the 12 patients who developed a local recurrence, 5 underwent a second endoscopic procedure, 5 a total laryngectomy, and 1 a supracricoid laryngectomy, and 1 was treated with radiotherapy. The 5-year local control rate with endoscopic surgery alone, according to the Kaplan-Meier method, was 91%. None of the variables (8 related to the tumor and 2 to the treatment) tested in a univariate analysis by the log-rank test was found to have a significant impact on disease-free survival rates. The present study confirmed that endoscopic partial cordectomy for Tis and T1 glottic cancers can be regarded as a valid alternative to radiotherapy in terms of oncological results.

Abstract
OBJECTIVE The goal of this study was to assess voice after radiotherapy compared with patients with presbylaryngeal dysphonia. STUDY DESIGN AND SETTING Prospective assessment of 20 patients aged 60+ years who remained free of disease longer than 1 year after radiotherapy for T1 squamous cell carcinoma and retrospective review of 46 patients aged 60+ with presbylaryngeal dysphonia, conducted at a tertiary care, academic hospital. Assessment data included videostroboscopy, spectrography, voice range profile, and Voice Handicap Index. RESULTS Eighty percent of the radiotherapy patients reported a voice disorder. Acoustic data and functional measures reflected similar limitations and abnormalities for both groups. A high incidence of glottal gap in all patients may have been associated with increased mucosal stiffness in the radiotherapy group and vocal fold atrophy in the presbylaryngeal group. CONCLUSION Patient perception and functional outcome of voice were similar for both groups, despite differences in etiology of abnormal vocal fold vibratory behavior. SIGNIFICANCE Radiotherapy in older individuals may yield dysphonia that is no greater than that caused by normal aging.

Abstract
Conservation surgery for cancers of the larynx and pyriform sinus is an expansive and complicated subject. A great deal of technical expertise and clinical judgement are required for appropriate surgical and oncologic outcomes. In the appropriate setting, surgery continues to play an important role in voice preservation for patients with laryngeal and hypopharyngeal carcinoma. Perhaps most importantly, options for organ preservation surgery have expanded, and the number of patients requiring total laryngectomy as primary surgical management has decreased. The medical surgical decision making is complex and requires precise delineation of tumor extent, careful patient evaluation, and thorough interdisciplinary discussion to select an optimal course of treatment for the individual patient.

Abstract
This study presents a cost analysis of and comparison between laser cordotomy and external beam irradiation for the treatment of early glottic carcinoma. It compares the curative results of the two modalities from data of a retrospective study at my institution and a literature review of published cure rates. It also reviews the results of objective voice assessments in cases representing both treatments. The findings of this study indicate that the cure rates are equivalent and that voice quality obtained after laser cordotomy is comparable to that obtained after irradiation, yet the total cost of external beam radiotherapy is significantly higher than that of laser surgery. Hence, the findings of this study provide strong support for initially treating early glottic tumors with laser surgery.

Abstract
We present the results of a retrospective study based on a cohort of 140 patients who underwent endoscopic CO(2) laser excision for previously untreated early glottic cancer (21 Tis, 96 T1, and 23 T2). This study used univariate analysis to review the impact on disease-free survival of 15 factors related to the host, the tumor, and the treatment. Recurrent cancer developed in 28 patients with an average interval to recurrence of 37.5 months. Retreatment consisted of different procedures, including laser excision, partial or total laryngectomy, and/or radiotherapy. The larynx was definitively preserved in 96% of patients. By the end of the study, 14 patients had died, but only 2 of them had died of the disease. Five-year overall survival and determinate survival were 93% and 98%, respectively. Ultimate local control at 5 years with CO(2) laser excision alone was 95% for Tis, 87% for T1, and 91% for T2 lesions. Only involvement of the anterior third of the vocal cord (P = 0.02), involvement of the false vocal cord (P = 0.02), and infiltration of the vocalis muscle (P = 0.004) showed a significant negative impact on disease-free survival.

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
PURPOSE The study of acoustic voice parameters (fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio) in extended vowel production, oral reading of a standard paragraph, spontaneous speech and a song in irradiated patients for Tis-T1 vocal cord carcinoma. METHODS AND MATERIALS Eighteen male patients irradiated for Tis-T1 vocal cord carcinoma and a control group of 31 nonirradiated subjects of the same age were included in a study of acoustic voice analysis. The control group had been rigorously selected for voice quality and the irradiated group had previous history of smoking in two-thirds of the cases and a vocal cord biopsy. Radiotherapy patients were treated with a 6MV Linac receiving a total dose of 66 Gy, 2 Gy/day, with median treatment areas of 28 cm(2). Acoustic voice analysis was performed 1 year after radiotherapy, the voice of patients in extended vowel production, oral reading of a standard paragraph, spontaneous speech, and in a song was tape registered and analyzed by a Kay Elemetric's Computerized Speech Lab (model CSL# 4300). Fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio were obtained in each case. Mann Whitney analysis was used for statistical tests. RESULTS The irradiated group presented higher values of fundamental frequency, jitter, shimmer, and harmonics-to-noise ratio. Mann-Whitney analysis showed significant differences for fundamental frequency and jitter in vowel production, oral reading, spontaneous speech, and song. Shimmer only showed differences in vowel production and harmonics-to-noise ratio in oral reading and song. CONCLUSIONS In our study only fundamental frequency and jitter showed significant increased values to the control group in all the acoustic situations. Sustained vowel production showed the worst values of the acoustic parameters in comparison with the other acoustic situations. This study seems to suggest that more work should be done in this field.

Abstract
BACKGROUND AND PURPOSE A cost minimization analysis of radiotherapy (RT), laser microsurgery (L) or partial laryngectomy (PL), which are equally effective options for T1N0 glottic SCC was carried out from the perspective of the National Health Care System. METHODS For each modality, the various events associated with the diagnostic procedure, the primary treatment, the complications, and the salvage treatment were individualized. The charges of each of these events weighted for the frequency of occurrence were then determined using the 'fee for service' policy established by the National Health Insurance of Belgium. RESULTS A total cost of 5172, 5847 and 11563 EURO were calculated for RT, L and PL, respectively. For L, cost included post-operative RT applied in case of positive margins (30%). For PL, the cost of the primary treatment accounted for 68% of the total cost whereas it only accounted for 50 and 43% for L and RT, respectively. For RT, L or PL, complications accounted for less than 10% of the total cost. The cost of salvage treatment reached 19, 14 and 8% of the total cost for RT, L and PL, respectively. A sensitivity analysis indicated that reduction of the duration of hospitalization decreases the costs without affecting the ranking between the three options. Also, the cost of L could be reduced even slightly below the cost of RT by decreasing the need for post-operative RT. CONCLUSIONS RT and L have almost the same expected average cost for the treatment of T1N0 glottic SCC, whereas PL is twice as expensive.

Abstract
OBJECTIVES To review the management and outcome of patients with new second primary cases of laryngeal cancer occurring more than 3 years after the initial cancer was treated. STUDY DESIGN Retrospective review of 855 patients with newly diagnosed and treated laryngeal cancers. METHODS Charts were reviewed and tabulated for occurrence of second primary laryngeal tumors, method of treatment for the index and second primary laryngeal tumors, and effect of smoking status or cessation of smoking. RESULTS Of the 855 patients, 532 patients retained their larynx; of these 377 lived more than 3 years and thus were at risk for a second new primary cancer. Of these 377 patients at risk, 19 or 5.1% developed second primary tumors. The rate of second primary disease was lower in patients whose index laryngeal cancer was treated by irradiation (4.3%) compared with those treated surgically (9.2%). However, surgical treatment of second primary laryngeal tumors resulted in far higher rates of laryngeal voicing (82%) compared with irradiation (33%). CONCLUSION When possible, management of the index primary tumor by endoscopic resection has resulted in the highest future retention of laryngeal speech, leaving all treatment options available should a second laryngeal cancer occur. Lifelong follow-up of patients with laryngeal cancer for secondary primary tumors is important. Second primary tumors were equally distributed between patients who continued to smoke and ceased to smoke after their index primary lesion was diagnosed.

Abstract
PURPOSE To assess consequences of voice impairment in daily life for patients following radiotherapy for early glottic cancer, by means of a multidimensional analysis protocol including voice quality, vocal function, and vocal performance measures. METHODS AND MATERIALS A total of 60 men treated with radiotherapy (66 Gy/33 fractions, 60 Gy/30 fractions, 60 Gy/25 fractions) for early T1 glottic cancer and 20 matched control speakers filled in questionnaires on vocal performance. Furthermore, perceptual analyses of voice quality and stroboscopic measures of vocal function were performed. There was a longitudinal group of 10 patients from whom data were collected before, as well as 6 months and 2 years after, radiation. Furthermore, data were collected on 5 separate groups of 10 patients each: before, 6 months after, 2 years after, 3-7 years after, and 7-10 years after radiation. RESULTS High correlations were found between self-ratings of vocal performance and several voice measures. Patients before radiotherapy experienced poor voice characteristics that improved 6 months to 10 years after treatment, and became comparable to vocal performance of control speakers in 50% of the patients. Following radiotherapy, deviant voice characteristics and consequences in daily life occurred significantly more often for patients in whom initial diagnosis consisted of stripping the vocal cord instead of biopsies and for patients who continued smoking after treatment. CONCLUSION Voice characteristics of patients diagnosed with early glottic cancer improved after radiotherapy, and became normal in half of our patients. Stripping the vocal cord for initial diagnosis and continued smoking after treatment decreased deviant voice characteristics.

Abstract
Treatment of benign vocal fold lesions by the use of the CO2 laser is discussed critically. The aim of the present prospective randomized study was to examine the post-operative functional results after laser phonosurgery in comparison to those after cold phonosurgery. In total, 44 patients with benign vocal fold lesions underwent surgery. Conventional cold phonosurgery was performed in 23 patients, and 21 patients were treated by laser phonosurgery. To determine vocal function, examinations were performed pre-operatively, on the second post-operative day, and one and four months post-operatively. The examinations included direct videolaryngoscopy, determination of maximal phonation, speech voice field as well as singing voice field. The results four months after surgery showed an improvement of vocal function in both treatment groups in comparison to the pre-operative findings. The improvement is only statistically significant after cold surgery.
