Gurău P. Awake endoscopic laser surgery for early glottic carcinoma. Lasers Med Sci 2024; 39:77. [PMID: 38386208 DOI: 10.1007/s10103-024-04027-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 02/18/2024] [Indexed: 02/23/2024]
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
PURPOSE Laser cordectomy is a widely accepted treatment modality for selected cases of early glottic cancers, but its role as a salvage treatment remains unclear. We aimed to investigate the oncological outcomes and failure patterns of salvage cordectomy. MATERIALS AND METHODS This was a retrospective cohort study of patients who underwent cordectomy for early glottic cancer between 2013 and 2022 at a tertiary referral center. The main outcome measures were overall survival, larynx-preservation rate, tracheostomy dependency rate, and disease-free survival. RESULTS A total of 142 patients (mean age: 63 years, interquartile range [IQR]: 45-72, 123[86.9 %] males) were analyzed. There were 38 (26.8 %) recurrences after a mean of 22 months (IQR: 17-26). Among them, 25 (17.6 %) underwent salvage cordectomy, while 13 (9.1 %) received other salvage treatments (11[7.7 %] (chemo)radiotherapy and 2[1.4 %] total laryngectomy). In comparison to the other salvage treatments, salvage cordectomy demonstrated lower tracheostomy rates (0 vs. 31 %, p = 0.05), comparable 5-year disease-free survival (62 % vs. 54 %, p = 0.4), higher 5-year larynx preservation rate (92 % vs. 54 %, p = 0.02), and improved 5-year overall survival rate (84 % vs. 62 %, p = 0.01). Factors associated with salvage cordectomy failure were age >60 years (odds ratio [OR]: 1.3, 95 % confidence interval [CI]: 1.15-1.53), smoking continuation (OR: 3.73, 95 % CI: 3.5-4.4), heavy smoking (OR: 1.24, 95 % CI:1.07-2.15), and pT1b + (OR: 2.26, 95 % CI: 2.1-2.9). CONCLUSIONS Salvage cordectomy offers favorable larynx preservation rates and oncological outcomes for recurrent disease amenable to conservative surgery. Smoking, advanced age, and advanced tumor stages are associated with salvage cordectomy failure.

Abstract
Could primary chemoradiotherapy (pCRT) possibly be viewed as an alternative standard therapy to upfront total laryngectomy (TL)? According to the new German S3 guideline, despite higher rates of local recurrence, there would be no survival disadvantage and salvage surgery would be a curative option. In several large database studies and case series, statistically significant survival disadvantages of more than 30% between pCRT and TL have been reported for T4 laryngeal cancer. According to the literature, the success rate of salvage TL for T4 laryngeal cancer is only about 25-50%. Larynx preservation (LP) studies which could qualify the recommendation of pCRT as an alternative standard therapy to TL in T4 carcinomas should 1) evaluate T4a cancers within the T4 category; 2) perform subgroup analysis of laryngeal and hypopharyngeal cancers; 3) be sufficiently highly powered; 4) provide long-term outcomes of at least 5 years; 5) with oncological and 6) functional outcomes (duration of the need for tracheostomy and/or feeding tube dependency; necessity and success of salvage laryngectomies). 7) Specification of the criteria of the respective T4 classification (invasion through the outer cortex of the cartilage, or infiltration of which extralaryngeal structures) and 8) evaluation of pretreatment laryngeal function (at least: tracheostomy, feeding tube dependency). Collection of all the aforementioned data of T4 patients treated with pCRT in a large prospective observational cohort study in German-speaking countries is suggested. In case of rejection of TL by T4 laryngeal cancer patients, differentiation between primary spontaneous reluctance and a definitive, carefully considered decision is important. This distinction should be achieved by sensitive discussions. Not only oncological but also functional outcome probabilities should be included in the overall decision-making process.

Abstract
BACKGROUND In head and neck cancer, distant metastases may be present at diagnosis (M1) or occur after treatment (DM). It is unknown whether M1 and DM follow the same clinical development and share prognosis, as population-based studies regarding outcomes are scarce. Therefore, we investigated the incidence, location of metastases and overall survival of patients with M1 and DM. MATERIALS AND METHODS Patients diagnosed with squamous cell carcinoma of the pharynx and larynx in Denmark 2008-2017 were identified in the Danish Head and Neck Cancer Group (DAHANCA) database. We identified 7300 patients, of whom 197 (3%) had M1 and 498 (8%) developed DM during follow-up. RESULTS The 5-year cumulative incidence of DM was 8%. 1- and 2-year overall survival for DM (27% and 13%) vs. M1 (28% and 9%) were equally poor. There was no significant difference in location of metastases for M1 and DM and the most frequently involved organs were lungs, bone, lymph nodes and liver, in descending order. In oropharyngeal squamous cell carcinomas, the location of metastases did not differ by p16-status. For p16-positive patients, 21% of DM occurred later than three years of follow-up compared to 7% of p16-negative patients. CONCLUSION Incidence, location of metastases and prognosis of primary metastatic (M1) or post-treatment metastatic (DM) disease in pharyngeal and laryngeal squamous cell carcinoma are similar in this register-based study.

Survival Outcomes and Predictors for Patients who Failed Chemoradiotherapy/Radiotherapy and Underwent Salvage Total Laryngectomy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18020371. [PMID: 33418958 PMCID: PMC7825052 DOI: 10.3390/ijerph18020371] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 12/26/2020] [Accepted: 01/01/2021] [Indexed: 11/17/2022]
Abstract
Background: To assess the presence of adverse pathological features at the time of salvage total laryngectomy (TL) associated with oncologic outcome. Methods: Ninety patients with persistent/locally recurrent disease and who subsequently underwent salvage TL after definitive treatment by radiation alone (RTO) or concurrent chemo-radiation (CCRT) from 2009 to 2018 were retrospectively enrolled. Kaplan–Meier methods were used to estimate overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). Results: Lymphovascular invasion (LVI), perineural invasion, positive margin, and stage IV disease were associated with worse survival in the univariate analysis. In the multivariate analysis, the presence of LVI and positive margin were both independent negative predictors in OS (LVI: adjusted hazard ratio (aHR) = 2.537, 95% CI: 1.163–5.532, p = 0.019; positive margin: aHR = 5.68, 95% CI: 1.996–16.166, p = 0.001), DSS (LVI: aHR = 2.975, 95% CI: 1.228–7.206, p = 0.016); positive margin: aHR = 11.338, 95% CI: 2.438–52.733, p = 0.002), and DFS (LVI: aHR 2.705, 95% CI: 1.257–5.821, p = 0.011; positive margin (aHR = 6.632, 95% CI: 2.047–21.487, p = 0.002). Conclusions: The presence of LVI and positive margin were both associated with poor OS, DSS, and DFS among patients who underwent salvage TL after failure of RTO/CCRT. The role of adjuvant therapy for high-risk patients after salvage TL to improve the chance of survival requires more investigation in the future.

Abstract
BACKGROUND We report outcomes for patients with T2N0M0 glottic squamous cell carcinoma (SCC) treated with radiation therapy (RT). METHODS Patients who received definitive RT for T2 glottic SCC from 2000 through 2013 were retrospectively reviewed. RESULTS One hundred and thirteen patients were analyzed (median follow-up time 91 months; 85 patients received three-dimensional conformal radiotherapy [3D-CRT] and 28 received intensity-modulated radiation therapy [IMRT]). Fractionation was conventional (58%) or altered (42%); 20 patients (18%) received concurrent chemotherapy. Five-year local control was 83% for the 3D-CRT vs 81% for the IMRT group (P = .76). The ultimate locoregional control at 5 years was 100% for IMRT vs 91% for 3D-CRT (P = .1). The 5-year overall survival (OS) was 78% for 3D-CRT vs 81% for IMRT (P = .83). On multivariate analysis, younger age was the only independent predictor of improved OS (P = .0002). CONCLUSIONS Oncologic and survival outcomes were excellent for patients with T2N0 glottic cancer. Patients treated with IMRT and 3D-CRT had no statistically significant differences in all investigated endpoints.

Functional Outcomes and Complications After Salvage Total Laryngectomy for Residual, Recurrent, and Second Primary Squamous Cell Carcinoma of the Larynx and Hypopharynx: A Multicenter Retrospective Cohort Study. Front Oncol 2020; 10:1390. [PMID: 32983968 PMCID: PMC7492266 DOI: 10.3389/fonc.2020.01390] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Accepted: 07/01/2020] [Indexed: 11/25/2022] Open
Abstract
Background/Purpose: We analyzed complications and functional outcomes and aimed at identifying prognostic factors for functional outcomes and complications in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx after initial (chemo)radiation. Methods: Retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018. Prognostic factors for functional outcomes and complications were identified with uni- and multivariable analysis. Results: A total of 405 patients were included in the final analysis. STL was performed for residual tumor (40.2%), local recurrence (40.5%), or second primary laryngeal or hypopharyngeal SCC (19.4%). Early postoperative complications were experienced by 34.2% of patients: postoperative hemorrhage occurred in 5.4%, wound infection in 16.2%, and clinical pharyngocutaneous fistula (PCF) in 25.5% of patients. Early readmission proved necessary in 15.1% of cases, most often due to late PCF development (72.2%). Patients achieved total peroral intake in 94.2% of cases. However, subjective dysphagia was reported by 31.3% of patients during follow-up. Functional speech, defined as functional communication by speech without additional aids, was reported in 86.7% of cases and was most often achieved by tracheo-esophageal puncture (TEP) (94.1%). In a multivariable model, lower preoperative hemoglobin (<12.5 g/dl) was identified as an independent prognostic factor for higher overall complication rate. No risk factors were found significant for clinical fistula formation. Vascularized tissue augmentation did not significantly prevent clinical PCF. Patients with positive section margins, patients initially treated with surgery combined with adjuvant RT (vs. radiotherapy alone), and those developing PCF after STL were less likely to achieve total peroral intake. Postoperative dysphagia proved more likely in patients who developed a PCF postoperatively, and less likely in patients who underwent STL without partial pharyngectomy and in patients with myocutaneous pectoralis major (PM) flap reconstruction, compared to muscle onlay PM flap. Achieving postoperative functional speech proved most likely in patients with smaller tumors (lower pT classification) and free section margins. Conclusion: Substantial complication rates and favorable functional outcomes are reported after STL.

Abstract
OBJECTIVES/HYPOTHESIS To analyze stapler benefits in salvage total laryngectomy in terms of surgical time, hospitalization length, oral feeding time, and occurrence of pharyngocutaneous fistula, and to evaluate risk factors for its onset. STUDY DESIGN Retrospective analysis. METHODS One hundred fourteen patients affected by endolaryngeal squamous cell carcinoma who underwent salvage total laryngectomy following primary treatment failure were reviewed. We divided patients into two groups based on type of pharyngeal suture performed: mechanical suture with stapler (group A) and manual suture (group B). These two groups were compared for surgical time, start of oral feeding, hospitalization length, surgical margins and pharyngocutaneous fistula incidence considering its relationship with diabetes mellitus, nutritional status, primary treatment, and neck dissection. RESULTS In group A and group B, oral feeding restarting time was 15 ± 9.33 versus 20.03 ± 13.81 days, hospitalization was 17.63 ± 10.08 versus 23.72 ± 14.29 days, and surgery lasted 268.39 ± 76.93 versus 294.26 ± 140.58 minutes, respectively (P < .05). Surgical margins resulted infiltrated in two patients (4.3%) in group A and 12 patients in group B (17.6%) (P = .03). Twenty-one patients (18.4%) presented with pharyngocutanoeus fistula. In group A and group B the incidence of fistula was 15.2% and 20.6%, respectively (P = .468). Fistula occurred in 7 of 18 diabetic patients (38.9%) and 14 of 96 (14.6%) nondiabetic patients (P = .015). Nineteen fistulas (90.5%) occurred in patients who had undergone previous radiation treatment (P = .013). CONCLUSIONS Using a stapler shortened operative time and hospitalization, while also providing a faster restart of oral feeding. Moreover, mechanical pharyngeal suture seems to decrease fistula rate even though its prevention role in salvage laryngectomy should be confirmed by further studies.

Abstract
AbstractBackgroundEarly laryngeal cancer treated with definitive radiotherapy or surgery has a high cure rate. This study evaluated the patterns of treatment failure and long-term results of early laryngeal cancers treated with definitive radiotherapy.MethodFrom January 2002 to December 2014, a total of 242 patients with early-stage laryngeal cancers were treated with radical radiotherapy.ResultsAll patients had squamous cell carcinoma of the larynx (92 per cent male and 8 per cent female). Median follow-up was 4.5 years. The majority of patients were smokers (57.4 per cent). Local failure was seen in 12.5 per cent of stage I patients and 22.8 per cent of stage II patients. The 5-year overall survival and disease specific survival were 84 per cent and 91 per cent, respectively.ConclusionIn summary, radiotherapy is a suitable treatment modality for patients with early-stage laryngeal cancer, with an overall locoregional control rate of 84 per cent. Patients who fail radiotherapy may still undergo salvage laryngectomy.

Abstract
Purpose The role of chemoradiation (CRT) in treating patients with early-stage glottic squamous cell carcinoma (SCC), especially for T2N0M0 glottic SCC with impaired vocal cord mobility, remains unexplored. We sought to evaluate the impact of CRT on survival in early-stage glottic SCC by using the SEER database. Patients and Methods We included patients with localized (T1-4N0M0) glottic SCC (N = 4,743) diagnosed between 2004 and 2014 and treated with definitive radiotherapy (RT) alone, CRT, or laryngectomy alone in the SEER database. Disease-specific mortality (DSM) was evaluated via multivariable regression using a competing risk model that accounts for other-cause mortality as a competing risk event for DSM. One-to-one propensity score matching between CRT and RT cohorts was also performed to facilitate comparison of cumulative DSM and other-cause mortality incidences stratified by T stage. Results After stratification by T stage, CRT was associated with increased DSM in T1-2N0M0 glottic SCC (adjusted hazard ratios [AHRs], 4.222 and 2.260 for T1 and T2 disease, respectively; P < .001 for both). For T2N0M0 glottic SCC with and without impaired vocal cord mobility, CRT resulted in significantly increased DSM compared with RT alone in both cohorts (AHR, 2.084; P = .046 and AHR, 2.412; P < .001, respectively). After propensity score matching, cumulative incidence plots demonstrated a statistically significant increase in DSM associated with CRT compared with RT alone for both T1 and T2 glottic SCC ( P < .001 and P = .003, respectively). Conclusion CRT for T1-2N0M0 glottic SCC was associated with increased DSM compared with RT alone. This pattern persisted upon further stratification on the basis of vocal cord mobility status for T2N0M0 glottic SCC. This finding warrants careful consideration of chemotherapy in early-stage glottic SCC.

Outcome of Early-Stage Glottic Laryngeal Carcinoma Patients Treated with Radical Radiotherapy Using Different Techniques. JOURNAL OF ONCOLOGY 2019; 2019:8640549. [PMID: 31781218 PMCID: PMC6874992 DOI: 10.1155/2019/8640549] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 08/19/2019] [Accepted: 10/10/2019] [Indexed: 11/17/2022]
Abstract
Purpose The aim was to evaluate the treatment outcomes and prognostic characteristics of patients with early-stage glottic laryngeal carcinoma who underwent radical radiotherapy (RT) with different techniques. Patients and Methods Radiotherapy was applied using the 2D conventional technique between 1991 and 2004 (130 patients), 3DCRT until 2014 (125 patients), and by VMAT until January 2017 (44 patients). Clinical T stages were 38 (12.7%) for Tis, 209 (69.9%) for T1, and 52 (17.4%) for T2. Radiotherapy technique and energy, anterior commissure involvement, and stage were analyzed as prognostic factors. Results The median total dose was 66 (50–70) Gy, and median follow-up time was 72 (3–288) months; 5-year disease-specific survival (DSS) rates were 95.8%, 95.5%, and 88.6%, respectively, in Tis, T1, and T2 stages. In multivariate analyses, anterior commissure involvement was found significant for all survival and local control rates. The patients treated with VMAT technique had better local control and DSS rates. However, these results were not statistically significant. Conclusion In early-stage laryngeal carcinomas, radical RT is a function sparing and effective treatment modality, regardless of treatment techniques.

Abstract
Laryngeal carcinomas are the most common upper respiratory tract cancers and most commonly involve the glottic region. The aim of this study is to evaluate the voice quality after radiotherapy (RT) and microsurgical cordectomy (MC) treatments using Voice Handicap Index (VHI) and Grade, Roughness, Breathiness, Astenicity, and Strain (GRBAS) perceptual evaluation scale in patients with early-stage glottic carcinoma. A total of 37 patients with early-stage glottic carcinomas, 19 patients had RT and 18 patients with MC, were included in our study. The patients were evaluated in terms of their sound quality by using VHI-10 and GRBAS perceptual assessment scale 3 months after the treatment was completed. Although the findings were better in favor of RT according to GRBAS perceptual assessment scale of patients who received RT (n = 19) and MC (n = 18), no statistically significant difference was found between the 2 groups (P = .613). Patients in both groups were evaluated with VHI-10, emotional (P = .036) and physiological (P = .038) scores were significantly higher in MC group and no significant difference was found in functional scores (P = .192). However, there was no statistically significant difference between the 2 groups in terms of voice quality (P = .185). In early-stage (Tis, T1a, T1b) glottic carcinoma, there was no significant difference between RT and MC in terms of voice quality. Therefore, the choice of treatment modality in patients with early-stage glottic carcinoma should be taken into account in terms of the patient's occupation, comorbid diseases, cost of treatment, hospital stay, and, most importantly, patient preference.

Abstract
OBJECTIVES The purpose of this study is to determine the effects of various prognostic factors for early glottic cancer patients who underwent radiotherapy. METHODS We retrospectively reviewed the all patients who were treated at our hospital for early glottic squamous cell carcinoma from 2004 to 2016. Data included patient's age, sex, T classification, tumor size, pathological grade, anterior commissure involvement, subglottic extension, laryngeal ventricle involvement, and restriction of vocal cord movement. RESULTS There were 74 patients with T1 tumors and 31 with T2 tumors. Recurrence was found in four patients with T1 and eight patients with T2. There were 99 males and six females enrolled, and the mean age was 67.5 ± 9.2 years for T1a, 67.3 ± 11.2 years for T1b, and 67.4 ± 7.9 years for T2. One patient with recurrence after 1 month was thought to have a residual tumor. The 5-year overall survival (OS) rate and the 5-year disease-specific survival (DSS) rate for T1-T2 patients were both 100%. The rate of larynx preservation was 94.6% for T1 and 74.2% for T2. A univariate analysis showed that the effective factors were age, T, size, SE. A multivariate logistic regression analysis showed that age influenced the recurrence status. Size is also suspected to be a prognostic factor. CONCLUSIONS This study revealed that the effective factors were age, T, size, and SE. LEVEL OF EVIDENCE 4 Laryngoscope, 130:1701-1706, 2020.

Abstract
BACKGROUND When a patient is seen with a newly diagnosed oropharyngeal squamous cell carcinoma, it remains unclear to the treating physicians how fast the tumor growth rate is. METHODS From patients with oropharynx squamous cell carcinoma treated by radiotherapy, the investigators selected comparable diagnostic CT-scan (DiCT) and radiotherapy planning CT-scan (RtCT). Tumor and pathological lymph node volumes were measured in order to calculate tumor progression. RESULTS From the selection of 19 patients, the mean absolute tumor progression rate was 0.23 ± 0.2 cm3 /d and mean relative progression rate was 1.84 ± 1.64%/d. Mean tumor doubling time is 286 days (range 7-1282 days), demonstrating a wide range of tumor growth pattern. Significant tumor progression (>20%) between DiCT and RtCT was shown in 73% of patients, and 53% of the patients were seen a tumor progression of >50% within a mean waiting time of 42.1 days. Kaplan-Meier curves showed a non-significative link between fast progression tumors (>1%/d) and higher risk of recurrence (HR: 2.2; P = .23). CONCLUSIONS Tumor progression can be assessed based on DiCT and RtCT. Treatment delay should be avoided at all cost. Different growth patterns were evidenced. For the fast-growing tumors subgroup, pejorative clinical outcomes were suggested. Prospective studies are needed to confirm a link between fast-growing tumors and higher risk for recurrence.

Abstract
The aim of the present study was to identify novel microRNA (miRNA) or long noncoding RNA (lncRNA) signatures of laryngeal cancer recurrence and to investigate the regulatory mechanisms associated with this malignancy. Datasets of recurrent and nonrecurrent laryngeal cancer samples were downloaded from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus database (GSE27020 and GSE25727) to examine differentially expressed miRNAs (DE-miRs), lncRNAs (DE-lncRs) and mRNAs (DEGs). miRNA-mRNA and lncRNA-miRNA networks were constructed by investigating the associations among these RNAs in various databases. Subsequently, the interactions identified were combined into a competing endogenous RNA (ceRNA) regulatory network. Feature genes in the miRNA-mRNA network were identified via topological analysis and a recursive feature elimination algorithm. A support vector machine (SVM) classifier was established using the betweenness centrality values in the miRNA-mRNA network, consisting of 32 optimal feature-coding genes. The classification effect was tested using two validation datasets. Furthermore, coding genes in the ceRNA network were examined via pathway enrichment analyses. In total, 21 DE-lncRs, 507 DEGs and 55 DE-miRs were selected. The SVM classifier exhibited an accuracy of 94.05% (79/84) for sample classification prediction in the TCGA dataset, and 92.66 and 91.07% in the two validation datasets. The ceRNA regulatory network comprised 203 nodes, corresponding to mRNAs, miRNAs and lncRNAs, and 346 lines, corresponding to the interactions among RNAs. In particular, the interactions with the highest scores were HLA complex group 4 (HCG4)-miR-33b, HOX transcript antisense RNA (HOTAIR)-miR-1-MAGE family member A2 (MAGEA2), EMX2 opposite strand/antisense RNA (EMX2OS)-miR-124-calcitonin related polypeptide α (CALCA) and EMX2OS-miR-124-γ-aminobutyric acid type A receptor γ2 subunit (GABRG2). Gene enrichment analysis of the genes in the ceRNA network identified that 11 pathway terms and 16 molecular function terms were significantly enriched. The SVM classifier based on 32 feature coding genes exhibited high accuracy in the classification of laryngeal cancer samples. miR-1, miR-33b, miR-124, HOTAIR, HCG4 and EMX2OS may be novel biomarkers of recurrent laryngeal cancer, and HCG4-miR-33b, HOTAIR-miR-1-MAGEA2 and EMX2OS-miR-124-CALCA/GABRG2 may be associated with the molecular mechanisms regulating recurrent laryngeal cancer.

Abstract
Purpose: The aim of our study was to report on patterns of failure using detailed information from follow-up positron emission tomography-computed tomography (PET/CT) scans for patients with laryngeal squamous cell carcinoma (SCCA) treated with definitive radiation therapy using intensity-modulated radiation therapy (IMRT). Methods: One hundred and sixty-eight patients with laryngeal SCCA treated with definitive IMRT using a simultaneous integrated boost were included. The point of recurrence origin on follow-up PET/CT was determined using two separate data-driven methods. The first method, the mathematical epicenter point of origin (POEpi), calculated the mathematical focal epicenter point for which the maximum distance to the surface of the surrounding volume was smaller than for any other point. The second method, maximum standardized uptake value point of origin (POMax), calculated the voxel with maximum standardized uptake value (SUV) uptake within the recurrence volume. The failure pattern was then determined by whether the point of recurrence origin fell within the low, intermediate, or high-risk target volumes in the original treatment planning CT. Results: Thirty-five primary/nodal recurrences in 33 patients were included in the analysis. In the POEpi method, 94% (33/35) of all recurrences originated either within the high-risk gross tumor volume (GTVHigh-risk) or within an average of 0.9 ± 1.3 mm from it. In the POMax method, 91% (32/35) of all recurrences originated either within the GTVHigh-risk or within an average of 1.8 ± 1.7 mm from it. There were no recurrences outside the low-risk planning target volume (PTVLow-risk) for the POEpi method but there was one for the POMax method, which was 19.8 mm away from the edge of the gross tumor volume receiving 70 Gy (GTV70). Increasing distance between the two different origin points was strongly correlated with the size of the recurrence volume. Conclusion: The majority of recurrences for laryngeal cancer patients treated with definitive IMRT originated from within the high-dose treatment region. This can have implications for reducing clinical target volumes while using a risk-adaptive treatment approach to both constrain dose to critical areas and further escalate the dose to the gross tumor to improve locoregional control rates.

Abstract
Aims and background To report results of hyperfractionated radiotherapy for T2N0 glottic carcinoma at a single institution after extended follow-up. Methods Between 1980 and 1988 at Varese University Hospital, 60 consecutive patients with T2N0 glottic carcinoma received exclusive radiotherapy consisting of 1.5 Gy/fraction twice a day. Treatment gaps during the radiotherapy course were allowed according to individual tolerance. This policy resulted in a wide range of elapsed treatment time: median, 5.7 weeks; range, 3.7-8.9. Median follow-up is 9.8 years. Results As a result of dose/time distribution, 16, 20 and 24 patients received an average weekly dose rate of <10 Gy/week, equal to 10 Gy/week or >10 Gy/week, respectively. Mean total dose for each group was 62.8 Gy, 63.7 Gy and 63.8 Gy, respectively. Five-year local-regional control was 69 ± 6% (95% Cl); ultimate local-regional control, including salvage surgery, was 78 ± 5%. All failures were at the primary site, and no patient developed neck recurrence as first site of failure. The actuarial incidence of grade 2-3 late reactions at 5 years was 42 ± 6%. Most late toxicity events were grade 2: only 2 patients developed grade 3 reactions and none grade 4. None of the several clinical and treatment-related variables showed any statistically significant impact on local-regional control or late toxicity at univariate and multivariate analysis. In particular, 3-year local-regional control rates were 73 ± 11%, 84 ± 8% and 69 ± 10% for an average weekly dose rate of <10 Gy/week, equal to 10 Gy/week and >10 Gy/week, respectively (not significantly different). Conclusions At a very long follow-up, the hyperfractionated regimen tested in the study was shown to be effective and devoid of major complications, provided individual patient acute tolerance is carefully taken into account. Also, time factor did not affect outcome in this series.

Abstract
BACKGROUND Larynx preservation (LP) is recommended for up to low-volume T4 laryngeal cancer as an evidence-based treatment option that does not compromise survival. However, a reevaluation of the current literature raises questions regarding whether there is indeed reliable evidence to support larynx preservation for T4 tumor patients. METHODS In an observational cohort study of 810 laryngeal cancer patients, we evaluated the outcomes of all T4 tumor patients treated with primary chemo-radiotherapy (CRT) or primary radiotherapy alone (RT) compared with upfront total laryngectomy followed by adjuvant (chemo)radiotherapy (TL + a[C]RT). Additionally, we reevaluated the studies that form the evidence base for the recommendation of LP for patients with up to T4 tumors (Pfister et al., J Clin Oncol 24:3693-704, 2006). RESULTS The evaluation of all 288 stage III and IV patients together did not show a significant difference in overall survival (OS) between CRT-LP and TL + a(C)RT (hazard ratio (HR) 1.23; 95% confidence interval (CI): 0.82-1.86; p = 0.31) using a multivariate proportional hazard model. However, a subgroup analysis of T4 tumor patients alone (N = 107; 13.9%) revealed significantly worse OS after CRT compared with TL + a(C)RT (HR 2.0; 95% CI: 1.04-3.7; p = 0.0369). A reevaluation of the subgroup of T4 patients in the 5 LP studies that led to the ASCO clinical practice guidelines revealed that only 21-45 T4 patients had differential data on survival outcome. These data, however, showed a markedly worse outcome for T4 patients after LP. CONCLUSIONS T4 laryngeal cancer patients who reject TL as a treatment option should be informed that their chance of organ preservation with primary conservative treatment is likely to result in a significantly worse outcome in terms of OS. Significant loss of survival in T4 patients after LP is also confirmed in recent literature.

Abstract
Objective To study preoperative counseling in patients undergoing salvage total laryngectomy (STL). Study Design Case series with chart review. Setting Tertiary care academic hospital. Subjects and Methods We reviewed charts of patients ≥18 years undergoing STL between 2005 and 2015. Fifty-eight patients were identified. Notes written within 2 months prior to surgery by head and neck surgical oncologists, radiation oncologists, medical oncologists, speech-language pathologists, social workers, and nurse practitioners were extracted and coded into 4 categories. Coded content was then analyzed using a simple tally within content areas. Results Nonphysicians documented patient values and priorities, exclusive of treatment desires, more frequently. These topics included apprehension about family obligations, fear about communication, questions regarding quality of life, and anxiety regarding job continuation. Physician notes documented priorities regarding preferences for surgical treatment. No patients were seen by palliative care preoperatively, and only 14% (n = 8) patients had documentation of an end-of-life discussion. Conclusions Preoperative counseling for STL patients that included nonphysicians had a higher frequency of discussion of patients’ priorities. This suggests including these types of providers may lead to more patient-centered care. A prospective study evaluating patient and physician perceptions of preoperative counseling can better identify where discrepancies exists and help conceptualize a framework for preoperative counseling in STL patients and other patients undergoing high-risk surgery.

Kitani Y, Kubota A, Furukawa M, Hori Y, Nakayama Y, Nonaka T, Mizoguchi N, Kitani Y, Hatakeyama H, Oridate N. Impact of combined modality treatment with radiotherapy and S-1 on T2N0 laryngeal cancer: Possible improvement in survival through the prevention of second primary cancer and distant metastasis. Oral Oncol 2017; 71:54-59. [PMID: 28688691 DOI: 10.1016/j.oraloncology.2017.05.017] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2017] [Revised: 05/20/2017] [Accepted: 05/27/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND In patients with head and neck cancer, the management of second primary cancer (SPC) is particularly important for improving survival because of its high incidence and associated mortality. We evaluated the impact of combination chemotherapy on survival and SPC. METHOD We retrospectively analyzed data from 49 patients treated with definitive radiation therapy (RT) for T2N0M0 laryngeal squamous cell carcinoma between 2003 and 2011. Among them, 22 patients received combined modality treatment with radiotherapy and S-1 (RT+CT group). RESULTS The median follow-up period was 71months (32-111months). A significant difference in overall survival (OS, P<0.01) was observed between the RT+CT group (n=22) and the RT alone group (n=27) though no significant differences were observed in local control and disease specific survival. Univariate analyses showed that an older age (P<0.05) and a higher grade (P<0.05) were associated with OS. Multivariate analysis identified chemotherapy as the most significant predictor of survival (OR, 0.056; 95% CI, 0.008-0.353, P<0.01). A significantly lower incidence of distant metastasis (DM)+SPC (5-year incidence: 5% vs. 19%, P<0.05) and fewer deaths from these causes (1 vs. 8: P<0.05) were observed in the RT+CT group. Multivariate analysis showed that chemotherapy was the most significant factor for the incidence of DM+SPC (OR, 0.074; 95% CI, 0.0065-0.84; P<0.05). CONCLUSION The findings of this study suggest the possibility that combined modality treatment with radiotherapy and S-1 improve survival by preventing distant metastasis and second primary cancer.

Park JW, Lee SW, Kim JS, Song SY. Prediction of local control in early glottic carcinoma using the maximum standardised uptake value. Cancer Radiother 2017; 21:205-209. [PMID: 28495481 DOI: 10.1016/j.canrad.2017.01.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2017] [Revised: 01/11/2017] [Accepted: 01/16/2017] [Indexed: 11/29/2022]
Abstract
PURPOSE This retrospective study aimed to determine whether the maximum standardised uptake value (SUVmax) can predict local tumour control in early glottic cancer (Tis, T1, and T2). PATIENTS AND METHODS Fifty-nine patients treated with definitive radiotherapy for early glottic cancer between 2003 and 2011 were enrolled. We evaluated the SUVmax in the region of interest around the original tumour site. Local tumour control and survival were estimated using Kaplan-Meier curves. Receiver operating characteristic curves were used to assess the optimal SUVmax cut-off for predicting local control. RESULTS As determined by laryngoscopy, all patients achieved a complete response. Eleven patients experienced local recurrence, while no distant metastasis occurred. One patient died due to local recurrence, while five lost their larynxes. The median follow-up was 61.5 (range: 6.2-123.4) months. The five-year local progression-free survival was 84.7%, and larynx preservation was possible in 89.6% of cases. The median SUVmax was 2.2. The optimal SUVmax for predicting local tumour control was identified as 3.4. Patients with glottic cancers with an SUVmax>3.4 showed a significantly lower local progression-free survival rate than those with tumours with an SUVmax<3.4 (five-year local progression-free survival rate: 53.4% vs. 95.4%, P<0.01). Multivariate analysis confirmed that a high SUVmax was an independent predictive factor for local progression-free survival (P=0.006). CONCLUSION The use of (18F)-fluorodeoxyglucose-positron emission tomography for evaluation of the SUVmax is useful to predict local progression-free survival in patients with early glottic cancer treated by radiation. Early glottic cancer with a high SUVmax may require aggressive local treatment and careful surveillance.

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

Abstract
After a local and/or regional recurrence of head and neck squamous cell carcinoma (HNSCC) not all patients are candidates to salvage treatment. The objective of this study was to identify the variables related to performance of salvage surgery with curative intent in these patients. We performed a retrospective study of 1088 HNSCC patients with a local and/or regional recurrence. According to a multivariate analysis, the variables related to performance of salvage surgery were the Karnofsky index, the location and extension of the primary tumor, the initial treatment, the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence, and the year the recurrence was diagnosed. Considering salvage surgery as the dependent variable, the results of a recursive partitioning analysis defined four categories of patients in function of the category of local and regional extension of the initial tumor, the location of the primary tumor, the initial treatment and the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence.

Abstract
OBJECTIVE: To assess the accuracy of preoperative imaging studies and clinical and endoscopic examinations for recurrent laryngeal carcinoma evaluation. STUDY DESIGN AND SETTING: A retrospective comparative study was performed at a university department on 42 recurrent laryngeal carcinomas. Surgical specimens were cut into whole-organ slices. Histologic findings were compared with the findings of the different preoperative diagnostic modalities. RESULTS: The craniocaudal tumor spread was correctly evaluated by endoscopy and imaging studies in 52% and 24%, respectively, and the contralateral tumor spread in 50% and 52%, respectively. The sensitivity, specificity, and accuracy for detection of tumor infiltration of the thyroid was 48%, 88%, and 64% and of the cricoid 47%, 80%, and 67%. The accuracy of recurrent tumor classification (crT) was 50%; most tumors were underclassified. CONCLUSION: The inadequately evaluated tumor spread and the inadequately classified recurrent tumors were underestimated and underclassified in most cases, respectively.

Abstract
OBJECTIVE: To analyze oncologic results in patients with glottic cancers treated respectively, by laser CO2 or open surgery, taking into account specific-disease survival, rate of locoregional recurrences, and their salvageability. STUDY DESIGN: Retrospective study of 198 patients treated from January 1993 to June 2002 in the department of otorhinolaryngology at a Catholic university in Rome. METHODS: Glottic carcinoma were treated by laser CO2 cordectomy in 132 patients (group 1) and by open surgery in 66 patients (group 2). The statistical analysis was performed by Kaplan Meyer method, log rank test, and x 2 , test. RESULTS: The log-rank test points out significant differences between the 2 groups regarding specific-disease survival; no differences were found for disease-free survival. Within group 1, 16 patients developed local failure, which was retreated in 6 cases with laser surgery; in 9 (6.8%) with total laryngectomy, only 1 case was inoperable. In this group, 10 patients (62.5%) were salvaged. Within group 2, 18 patients developed local recurrences, which was retreated in 14 (21.21%) cases with total laryngectomy; the other 4 cases were not suitable for surgery. Of these 18, 8 patients (44.5%) were salvaged. CONCLUSIONS AND SIGNIFICANCE: Our results show significant differences between the 2 groups concerning the specific-disease survival and the salvageability of local recurrences. In fact, in group 1 we found a higher salvage rate and a lower incidence of total laryngectomy. As already suggested, laser therapy leaves the laryngeal cartilaginous framework intact, avoiding the spread of the tumor out of laryngeal organ and resulting in a more favorable oncologic outcome.

Abstract
Purpose The aim of the study was to test the hypothesis that head and neck cancer (HNC) patients benefit from specialized follow-up (FU), as this strategy ensures timely detection of relapses for successful salvage treatment. This was done by evaluation of the pattern of failure, the temporal distribution of recurrences, and the outcome of salvage treatment in a contemporary cohort of HNC patients. Methods The study evaluated a cohort of 2062 consecutive patients treated with curative intent at Aarhus University Hospital from 1 January 2000 to 31 December 2013. The database of DAHANCA contained recordings of recurrent disease in 567 patients with primary tumors of the larynx, pharynx, oral cavity, nasal cavity, paranasal sinuses and salivary glands. A review of medical records was performed in order to update and supplement the database. Results Failures of the 567 patients were primarily in T-site (65%) followed by N-site (36%) and M-site (22%). The vast majority of the first recurrences occurred within the first years after primary treatment; 62%, 82%, and 91% within the first, second and third year, respectively. Totally, 51% were amenable for salvage treatment, and 44% benefited from salvage in terms of a complete response. Permanent tumor control was observed in 128 patients (23%) after one or two salvage attempts. The highest salvage rate was recorded in patients with primary glottic carcinoma (41%) and the lowest among hypopharyngeal cancers (2%). Asymptomatic recurrence was recorded in 12% of all recurrences and this was found to be a positive prognostic factor for disease-specific survival, as they had significantly better outcome after salvage. Conclusion Our data support the usefulness of specialized FU in terms of early detection of recurrent disease. In particular patients with silent recurrences benefited from early detection, as they had a significantly lower risk ratio of death from primary HNC.

Incidence of and survival after glottic squamous cell carcinoma in Denmark from 1971 to 2011-A report from the Danish Head and Neck Cancer Group. Eur J Cancer 2016; 59:46-56. [PMID: 27014799 DOI: 10.1016/j.ejca.2016.01.020] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 01/19/2016] [Accepted: 01/31/2016] [Indexed: 01/22/2023]
Abstract
AIM To describe the incidence, disease-specific mortality (DSM), and overall survival (OS) of patients with glottic squamous cell carcinomas (SCC) in Denmark from 1971-2011 in a national population-based cohort of consecutive patients. MATERIALS AND METHODS All patients diagnosed with glottic SCC stage I-IV between 1971 and 2011 in Denmark were included. Patients were identified from the Danish Head and Neck Cancer database, which has a coverage of approximately 100% of registered glottic cancer in Denmark. Information on vital status and cause of death were updated using patient charts and national registries. RESULTS In total 5132 patients with glottic SCC were included. The yearly number of new cases increased from 107 in the 1970s to 139 in the 2000s. Overall, the incidence increased from 1.9 to 2.6 per 100,000, with a more prominent increase in men (3.5 to 4.7) compared with women (0.4 to 0.6). The 5-year DSM was 16% (15-17%) and the 5-year OS was 63% (61-64). The hazard rate of DSM adjusted for patient characteristics, tumour characteristics and waiting-time was significantly lower in the 2000s (p < 0.01), and the hazard rate of OS was significantly higher (p < 0.01) compared to the earlier decades. Longer waiting-time for treatment (>25 d) significantly increased DSM and reduced OS. CONCLUSION Despite being highly avoidable with smoking cessation, the incidence of glottic SCC increased in Denmark from 1971-2011. The adjusted hazard rate of DSM and overall death after glottic SCC was significantly lower in the 2000s compared to previous decades. Waiting-time for treatment significantly influenced DSM and OS.

Abstract
PURPOSE To describe the pattern of failure in a national consecutive cohort of patients with glottic squamous cell carcinomas (SCC) treated with primary radiotherapy (RT) with curative intent over a 41-year period. MATERIALS AND METHODS All patients undergoing curative treatment for a glottic SCC diagnosed in Denmark between 1971 and 2011 were included and followed from the first contact with the oncology center to death or February 15, 2015. RESULTS 5001 patients were identified of whom 98% had primary RT. The median follow-up was 9.1 years/5.7 years (patients alive/patients who died). Ten patients were lost to follow-up. In total 1511 failures were observed; of these 93%, 11% and 5% included T site, N site, and M site, respectively. For patients diagnosed in the 70s and the 00s, respectively, the five-year incidences were: local failure (32% vs 19%), loco-regional failure (34% vs 21%), laryngectomy (26% vs 10%), laryngectomy-free survival (48% vs 62%), disease-free survival (62% vs 68%), and overall survival (62% vs 68%). The five-year incidence of ultimate failure (13-16%) remained statistically unchanged. CONCLUSION From the 70s to the 00s a continually improving primary disease-control was observed with a concurrent decrease in the incidence of laryngectomy. The survival rate was significantly higher in the 00s compared to the previous three decades.

Abstract
PURPOSE The DAHANCA 6 trial evaluated tumor response and morbidity after moderate accelerated radiotherapy compared to conventional fractionated radiotherapy in patients treated for glottic squamous cell carcinoma (SCC). Further, the failure pattern and incidence of new primary tumors were explored. PATIENTS AND METHODS Six hundred and ninety-four patients with non-metastatic glottic SCC were randomized between six or five weekly fractions (fx/w) of radiotherapy to the same total dose. The median treatment time was 38 and 46days, respectively. The primary endpoint was loco-regional failure. RESULTS Median follow-up time was 14.5years. Of the 177 failures, 167 involved T-site. The cumulative incidence of loco-regional failure (LRF) was 21.6% in the 6fx/w group and 29.3% in the 5fx/w group and the corresponding hazard rate (HR) of LRF was 0.72 (CI: 0.53-0.97, p=0.04). The effect of acceleration on LRF was especially evident in well differentiated tumors (HR=0.42 (CI: 0.23-0.75) and in T1-2 tumors (HR=0.60 (CI: 0.41-0.89)). The HR of laryngectomy was 0.72 (CI: 0.50-1.04) in the 6fx/w group compared to the 5fx/w group. The hazards of disease-specific death, event-free survival, and overall survival were comparable between the two groups. Significantly more patients experienced severe acute mucositis in the 6fx/w group but the incidence of late morbidity was comparable between the groups. New primary tumors occurred in 22.5% of the patients. CONCLUSION Moderate accelerated radiotherapy significantly improved loco-regional control in patients with glottic SCC.

Abstract
BACKGROUND Many cancer patients who are smokers when starting cancer therapy continue smoking despite evidence of tobacco smoking as a risk factor for poor treatment response and secondary primary cancers. Small samples and inconsistent results in previous studies warrant further research to identify predictors of being a continuous smoker during and after radiotherapy. MATERIAL AND METHODS In the clinical database of the Danish Head and Neck Cancer Group (DAHANCA), we identified 1455 patients diagnosed with laryngeal cancer between 2000 and 2010, who were all smokers at date of diagnosis and treated with primary radiotherapy. Information on the socio-economic characteristics of the study cohort was obtained from Statistics Denmark the year prior to diagnosis. Logistic regression analyses were applied. RESULTS In the cohort of laryngeal cancer patients smoking before starting radiotherapy, 50% still smoked one year after radiotherapy similar to the percentage of smokers during treatment. Being younger than 60 years (OR 1.39, 95% CI 1.00-1.91), commenced smoking before the age of 15 (OR 1.77, 95% CI 1.32-2.38), having a poor WHO Performance status (OR 3.09, 95% CI 1.71-5.61), low income (OR 2.21, 95% CI 1.23-3.98) and living alone (OR 1.56, 95% CI 1.13-2.14) were associated with increased risk of continuous smoking during treatment. Similar findings were found two months and one year after radiotherapy, however, no association with living alone (OR 1.08, 95% CI 0.73-1.59) at the one-year follow-up. Tumor stage and the average number of cigarettes smoked per day before radiotherapy were not associated with being a continuous smoker. CONCLUSION Younger patients, who had an early smoking initiation, a poor performance status, low income and lived alone, were most likely to continue smoking. Continuous smoking was not related to the extent of disease.

Abstract
PURPOSE Squamous cell carcinoma of larynx with subglottic extension (sSCC) is a rare location described to carry a poor prognosis. The aim of this study was to analyze outcomes and feasibility of larynx preservation in sSCC patients. PATIENTS AND METHODS Between 1996 and 2012, 197 patients with sSCC were treated at our institution and included in the analysis. Stage III-IV tumors accounted for 76%. Patients received surgery (62%), radiotherapy (RT) (18%), or induction chemotherapy (CT) (20%) as front-line therapy. RESULTS The 5-year actuarial overall survival (OS), locoregional control (LRC), and distant control rate were 59% (95% CI 51-68), 83% (95% CI 77-89), and 88% (95% CI 83-93), respectively, with a median follow-up of 54.4 months. There was no difference in OS and LRC according to front-line treatments or between primary subglottic cancer and glottosupraglottic cancers with subglottic extension. In the multivariate analysis, age > 60 years and positive N stage were the only predictors for OS (HR 2, 95% CI 1.2-3.6; HR1.9, 95% CI 1-3.5, respectively). A lower LRC was observed for T3 patients receiving a larynx preservation protocol as compared with those receiving a front-line surgery (HR 14.1, 95% CI 2.5-136.7; p = 0.02); however, no difference of ultimate LRC was observed according to the first therapy when including T3 patients who underwent salvage laryngectomy (p = 0.6). In patients receiving a larynx preservation protocol, the 5-year larynx-preservation rate was 55% (95% CI 43-68), with 36% in T3 patients. The 5-year larynx preservation rate was 81% (95% CI 65-96) and 35% (95% CI 20-51) for patients who received RT or induction CT as a front-line treatment, respectively. CONCLUSION Outcomes of sSCC are comparable with other laryngeal cancers when managed with modern therapeutic options. Larynx-preservation protocols could be a suitable option in T1-T2 (RT or chemo-RT) and selected T3 sSCC patients (induction CT).

Abstract
BACKGROUND Squamous cell carcinoma of larynx with subglottic extension is a rare location described to carry a poor prognosis. The aim of this study was to analyze outcomes and feasibility of definitive radiotherapy in patients with squamous cell carcinoma. PATIENTS AND METHODS Between 1998 and 2012, 56 patients with squamous cell carcinoma were treated at our institution and included in the analysis. Patients received definitive radiotherapy/chemoradiotherapy alone (63%) or after induction chemotherapy (37%) at our institute. RESULTS The 5-year actuarial overall survival, progression-free survival and specific survival were 64% (CI 95%: 48-90), 45% (CI 95%: 28-61), 88% (CI 95%: 78-98), respectively, with median follow-up of 74 months. The 5-year locoregional control was 69% (CI 95%: 56-83) and the 5-year distant control was 95% (CI 95%: 89-100). There was no difference in overall survival and locoregional control according to front-line treatments or between primary subglottic cancer and glotto-supraglottic cancers with subglottic extension. In the multivariate analysis, performance status of at least 1 and positive N stage were the only predictors for overall survival (hazard ratio [HR] [CI 95%]: 6.5 [1.3-34; P=0.03] and 11 [1.6-75; P=0.02], respectively). No difference of locoregional control was observed according to the first received therapy. The univariate analysis retrieved that T3-T4 patients had a lower locoregional control (HR: 3.1; CI 95%: 1.1-9.2, P=0.04), but no prognostic factor was retrieved in the multivariate analysis. In patients receiving a larynx preservation protocol, 5-year larynx preservation rate was 88% (CI 95%: 78-98), and 58% in T3 patients. The 5-year larynx preservation rate was 91% (CI 95%: 79-100) and 83% (CI 95%: 66-100) for patients who received radiotherapy/chemoradiotherapy or induction chemotherapy as a front-line treatment, respectively. CONCLUSION This analysis suggests that the results for squamous cell carcinoma patients treated with radiotherapy/chemoradiotherapy are comparable to those obtained for other laryngeal tumors. This thus suggests the feasibility of laryngeal preservation protocols for infringement subglottic for selected cases. Further studies are needed to clarify these preliminary data.

Abstract
OBJECTIVE We analyzed the clinical outcomes of 849 laryngeal cancers treated in the past 40 years, which overlapped with the era of the global treatment shift. METHODS To compare the chronological outcomes, patients were divided into four groups according to their registration year as 1972-82, 1983-92, 1993-2002 and 2003-12; treatment trends, larynx preservation rate and overall survival rate were compared. RESULTS There were 104, 173, 253 and 319 patients registered in 1972-82, 1983-92, 1993-2002 and 2003-12, respectively. Five-year overall survival rates were 74, 76.5, 75.6 and 82.2% in 1972-82, 1983-92, 1993-2002 and 2003-12, respectively. The five-year larynx preservation rates were 65.5, 75.7, 75.4 and 80.9% in 1972-82, 1983-92, 1993-2002 and 2003-12, respectively. CONCLUSIONS The number of patients treated at our institute increased, and the overall survival and larynx preservation rates exhibited favorable improvements over the past four decades. In the analysis of nonsurgical options, S1 combined radiotherapy showed superiority over concurrent chemoradiotherapy and radiotherapy in larynx preservation, and S1 combined radiotherapy, concurrent chemoradiotherapy and Tegafur Uracil combined radiotherapy showed superiority over radiotherapy in overall survival. In nonsurgical approaches, proper case selection is the key to success and may be much more important than pursuing radiotherapy dose escalation. In the analysis of surgical options, laser and supracricoid laryngectomy with cricohyoidoepiglottopexy contributed to larynx preservation in early- and intermediate-stage cancers, respectively. Supracricoid laryngectomy with cricohyoidoepiglottopexy demonstrated overall survival not worse than total laryngectomy, which is the prerequisite treatment basis for larynx preservation options. We must make extra efforts in pursuing an ideal balance between nonsurgical and surgical larynx preservation options.

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
OBJECTIVE Review of the literature on the role of surgery in the management of head and neck cancer in the era of organ preservation. METHOD Literature search based on the essential practice guidelines set out by the US National Comprehensive Cancer Network. RESULTS Despite the increasing popularity of non-surgical treatment options, the surgeon remains a key figure in the multidisciplinary head and neck cancer team, along with the radiation oncologist, the medical oncologist and the speech and swallowing therapist. Even when organ preservation is successful, early and late toxicity may cause serious complications, including laryngeal dysfunction with a 'frozen larynx'. When organ preservation fails, salvage surgery is often associated with increased complications and reduced survival. CONCLUSION There is a definite need to apply more rigorous standards to the use of organ preservation strategies, and to re-evaluate the role of surgery in head and neck cancer treatment.

Abstract
AIMS To determine the influence of dose and fractionation on tumour characteristics, toxicity, disease control and survival outcomes in T1 glottic carcinoma. MATERIALS AND METHODS Between 1975 and 2000, treatment charts of 652 patients with T1 glottic carcinoma who received curative radiation with four hypofractionated schedules (50 Gy/15 fractions [3.3 Gy/fraction] or 55 Gy/16 fractions [3.43 Gy/fraction] or 60 Gy/24 fractions or 62.5 Gy/25 fractions [2.5 Gy/fraction]) were analysed. The patients were divided into two groups based on fraction size <3 Gy and >3 Gy. Local control and overall survival were calculated. Patient- and tumour-related factors affecting local control were analysed using univariate and multivariate analysis. Factors affecting late toxicity were also analysed. RESULTS The local control and overall survival at 10 years were 84 and 86.1%, respectively, for T1 glottic carcinoma. The response to radiation had a significant effect on local control with univariate analysis (P = 0.001). Other factors, such as beam energy, anterior commissure involvement and fractionation, did not affect local control. Persistent radiation oedema was seen in 123 patients (23.4%) and was significantly worse in patients who received radiation with a larger field size (>36 cm(2)) on a telecobalt machine (P < 0.001). CONCLUSIONS Radical radiotherapy schedules incorporating a higher dose per fraction yield acceptable local control rates and late toxicity. Telecobalt therapy for early glottic cancer is a safe alternative to treatment with 6 MV photons on a linear accelerator in terms of local control and late toxicity as long as field sizes smaller than 36 cm(2) are used.

Abstract
The principles of open versus laser microsurgical approaches for partial resections of the larynx are described, oncologic as well as functional results discussed and corresponding outcomes following primary radiotherapy are opposed. Over the last decade, the endoscopic partial resection of the larynx has developed to an accepted approach in the treatment of early glottic and supraglottic carcinomas thus leading to a remarkable decline in the use of open surgery. Comparing the various surgical approaches of laryngeal partial resections, the oncological outcome of the patients, as far as survival and organ preservation are concerned, are comparable, whereas functional results of the endoscopic procedures are superior with less morbidity. The surgical procedures put together, are all superior to radiotherapy concerning organ preservation. Transoral laser microsurgery has been used successfully for vocal cord carcinomas with impaired mobility or fixation of the vocal cord, supraglottic carcinomas with infiltration of the pre- and/or paraglottic space as well as for selected hypopharyngeal carcinomas. It has been well documented that laser microsurgery achieves good oncological as well as functional results with reasonable morbidity. However, patients with those tumours have been successfully treated by open partial resections of the larynx at medical centres with appropriate expertise. The initially enthusiastic assessment of study results concerning the efficacy of various protocols of chemoradiation with the intent of organ preservation for laryngeal and hypopharyngeal carcinomas are judged more cautious, today, due to recent reports of rather high rates of late toxicity complications.

Abstract
Objective. To find the survival rate of patients ≥80 years old who undergo salvage surgery for squamous cell carcinoma of the larynx. Study Design. National data registry analysis. Setting. Seventeen population-based registries comprising the National Cancer Institute’s Surveillance, Epidemiology, and End Results database. Subjects and Methods. Overall, cancer-specific, and relative survival rates were calculated from 1418 patients, stratified into 3 age cohorts, who underwent surgery following radiation therapy for treatment of laryngeal cancer. Results. The 1-year overall survival of patients ≥80 years old (n = 57) was 76.1%. The cancer-specific survival at 1 year was 86.4%. These survival rates were significantly less than those of patients <65 years old (n = 869), who had a 1-year overall survival of 88.1% ( P = .006) and cancer-specific survival of 90.5% ( P = .029). Patients aged between 65 and 79 years old (n = 492) displayed 1-year overall survival of 80.7% ( P = .426) and cancer-specific survival of 85.1% ( P = .711), which were not significantly different from the ≥80 year cohort. When comparing relative survival at 5 years, the ≥80-year-old cohort’s survival trended the highest (≥80 years, 62.8%; 65-79 years, 51.3%; 20-64 years, 56.2%). Conclusion. While patients ≥80 years old have a less favorable prognosis than patients <65 years old, the survival rates of patients ≥80 years old are not significantly different from the 65- to 79-year-old cohort. After controlling for non-cancer-related death, patients ≥80 years old appear to have similar 5-year survival outcomes compared with other patients.

Impact and relationship of anterior commissure and time-dose factor on the local control of T1N0 glottic cancer treated by 6 MV photons. Radiat Oncol 2011; 6:53. [PMID: 21600025 PMCID: PMC3124409 DOI: 10.1186/1748-717x-6-53] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2011] [Accepted: 05/21/2011] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To evaluate prognostic factors that may influence local control (LC) of T1N0 glottic cancer treated by primary radiotherapy (RT) with 6 MV photons. METHODS We retrospectively reviewed the medical records of 433 consecutive patients with T1N0 glottic cancer treated between 1983 and 2005 by RT in our institution. All patients were treated with 6 MV photons. One hundred and seventy seven (41%) patients received 52.5 Gy in 23 fractions with 2.5 Gy/fraction, and 256 (59%) patients received 66 Gy in 33 fractions with 2 Gy/fraction. RESULTS The median follow-up time was 10.5 years. The 10-year LC rates were 91% and 87% for T1a and T1b respectively. Multivariate analysis showed LC rate was adversely affected by poorly differentiated histology (Hazard Ratio [HR]: 7.5, p = 0.035); involvement of anterior commissure (HR: 2.34, p = 0.011); fraction size of 2.0 Gy (HR: 2.17, p = 0.035) and tumor biologically effective dose (BED) < 65 Gy15 (HR: 3.38, p = 0.017). CONCLUSIONS The negative impact of anterior commissure involvement could be overcome by delivering a higher tumor BED through using fraction size of > 2.0 Gy. We recommend that fraction size > 2.0 Gy should be utilized, for radiation schedules with five daily fractions each week.
