Targeting Anterior Commissure Involvement with Hyperfractionated Radiotherapy for T1-T2 Squamous Cell Carcinoma of the Glottic Larynx. Cancers (Basel) 2024; 16:1850. [PMID: 38791929 PMCID: PMC11119720 DOI: 10.3390/cancers16101850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/25/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024] Open
Abstract
Anterior commissure is involved in about 20% of early-stage glottic squamous cell carcinomas (EGSCCs). Treatment outcomes and prognostic factors for EGSCC with anterior commissure involvement (ACI) were evaluated by focusing on hyperfractionated radiotherapy (74.4 Gy in 62 fractions). One-hundred and fifty-three patients with T1-T2 EGSCC were included in this study. The median total doses for T1a, T1b, and T2 were 66, 74.4, and 74.4 Gy, respectively. Overall, 49 (32%) patients had T1a, 38 (25%) had T1b, and 66 (43%) had T2 disease. The median treatment duration was 46 days. The median follow-up duration was 5.1 years. The 10-year overall and cause-specific survival rates were 72% and 97%, respectively. The 10-year local control rates were 94% for T1a, 88% for T1b, and 81% for T2 disease. Local control rates in patients with ACI were slightly better than those in patients without ACI with T1a and T1b diseases; however, the difference was not significant. The 10-year laryngeal preservation rate was 96%. Six patients experienced grade 3 mucositis, and four patients had grade 3 dermatitis. Hyperfractionated radiotherapy was effective for T1 disease with ACI, but insufficient for T2 disease with ACI. Our treatment strategy resulted in excellent laryngeal preservation.

Int J Radiat Oncol Biol Phys 2023; 117:652-663. [PMID: 37150263 DOI: 10.1016/j.ijrobp.2023.04.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 04/03/2023] [Accepted: 04/29/2023] [Indexed: 05/09/2023]
Abstract
PURPOSE Early-stage squamous cell carcinoma of the glottic larynx is commonly treated with 2-dimensional or 3-dimensional conventional radiation therapy (CRT). Despite its use in other head and neck cancers, intensity-modulated radiation therapy (IMRT) remains controversial in this patient population. METHODS AND MATERIALS A systematic review was performed by querying 3 databases (Pubmed, Embase, Web of Science) for articles published between December 1, 2000 and September 2, 2022. Included studies reported outcomes in at least 10 patients treated with IMRT for early-stage glottic cancer. Data were extracted and reported following PRISMA standards. Pooled outcomes were estimated using random-effects models. Primary outcome was the rate of local failure (LF) following IMRT. Secondary outcomes included rates of regional failure (RF) following IMRT and rates of LF and RF following CRT. RESULTS A total of 15 studies (14 retrospective, 1 prospective) consisting of 2083 patients were identified. IMRT was used in 873 patients (64% T1, 28% T2). Multiple treatment (partial larynx, single vocal cord carotid sparing) and image-guided radiation therapy techniques were used. The pooled crude rate of LF was 7.6% (95% confidence inverval [CI], 3.6%-11.5%) and actuarial LF rates at 3 and 5 years were 6.3% (95% CI, 2.2%-10.3%) and 9.0% (95% CI, 4.4%-13.5%), respectively. The pooled crude rate of RF after IMRT was 1.5% (95% CI, 0.5%-2.5%). On metaregression analysis, increased rate of LF was significantly associated with T2 disease (P < .001) and grade 2 to 3 histology (P < .001). Treatment with CRT was reported in 738 patients (76% T1, 22% T2). Among the studies reporting outcomes of both modalities, there was no significant difference in LF (log odds ratio; P = .12) or RF (log odds ratio; P = .58) between IMRT or CRT. CONCLUSIONS In patients with early-stage glottic cancer, retrospective data suggests local and regional control are similar for patients treated with IMRT and CRT. Additional prospective studies with uniform methods of volume delineation and image guidance are needed to confirm the efficacy of IMRT.

Abstract
PURPOSE The prognoses of T1a and T1b glottic cancers are still controversial. This study aimed to compare the prognosis difference between the two groups based on the population-based Surveillance, Epidemiology, and End Results database (SEER). METHODS Data for patients with T1a or T1b glottic cancers were extracted from the SEER database. The bias between T1a and T1b glottic cancers was minimized with Propensity Score Matching (PSM), and disease-specific survival (DSS) was analyzed using the Kaplan-Meier method, log-rank test, and Cox proportional hazards models. RESULTS A total of 5,272 patients were extracted from the database, including 847 patients with T1b glottic cancer that were 1:1 propensity score-matched with patients with T1a glottic cancer. After propensity score-matching, there was no statistical difference in disease-specific survival between T1a and T1b patients, whilst survival was impaired by old age. However, on the multivariate analysis, the T1a stage was associated with improved DSS compared with the T1b stage. CONCLUSION Our analysis showed that T1a glottic cancers didn't have a significantly better prognosis compared with T1b after PSM. However, the DSS of T1a patients is superior to that of T1b patients in multivariate analysis.

Oncological and Functional Outcomes for Horizontal Glottectomy: A Systematic Review. J Clin Med 2023; 12:jcm12062261. [PMID: 36983261 PMCID: PMC10059705 DOI: 10.3390/jcm12062261] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 02/23/2023] [Accepted: 03/11/2023] [Indexed: 03/17/2023] Open
Abstract
Horizontal glottectomy (HG) is a particular type of partial laryngectomy indicated for exclusive glottic tumor with anterior commissure involvement. The purpose of this study is to systematically review the literature about functional and oncological outcome of HG. This systematic review adhered to the recommendations of the PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analysis) 2009 guidelines. Articles mentioning patients undergoing HG for laryngeal squamous cell carcinoma were included. A total of 14 articles were selected and reviewed from 19 identified. The whole study population consisted of 420 patients who underwent HG. Three hundred and thirty-nine patients out of 359 were staged as T1. The range of post-operative follow-up was 5 months to 10 years. Fifty-five recurrences were experienced, being local, regional and distant in 35, 12 and 8 patients, respectively. Laryngeal preservation rate was 93.6%. Nasogastrict tube was removed on average after 10.1 days. The tracheostomy was maintained for 11.3 days. Mean hospitalization lasted for 11.7 days. According to the results of this systematic review, HG is an oncologically safe surgical option for T1a–T1b glottic tumors with oncological outcomes comparable to other treatment. HG could be a good therapeutical choice whenever poor laryngeal exposure and/or patient’s refusal of radiotherapy are encountered, or when patient’s medical history represents a contraindication for radiation therapy.

Abstract
PURPOSE Early-stage glottic cancer can be treated with radiotherapy only. Modern radiotherapy solutions allow for individualized dose distributions, hypofractionation and sparing of organs at risk. The target volume used to be the entire voice box. This series describe the oncological outcome and toxicity of individualized vocal cord-only hypofractionated radiotherapy for early stage (cT1a-T2 N0). METHODS Retrospective cohort study with patients treated in a single center between 2014 and 2020. RESULTS A total of 93 patients were included. Local control rate was 100% for cT1a, 97% for cT1b and 77% for cT2. Risk factor for local recurrence was smoking during radiotherapy. Laryngectomy-free survival was 90% at 5 years. Grade III or higher late toxicity was 3.7%. CONCLUSION Vocal cord-only hypofractionated radiotherapy appears to be oncologically safe in early-stage glottic cancer. Modern, image-guided radiotherapy led to comparable results as historical series with very limited late toxicity.

Vocal-cord Only vs. Complete Laryngeal radiation (VOCAL): a randomized multicentric Bayesian phase II trial. BMC Cancer 2021; 21:446.

Abstract
BACKGROUND Radiotherapy, along with laser surgery, is considered a standard treatment option for patients with early glottic squamous cell cancer (SCC). Historically, patients have received complete larynx radiotherapy (CL-RT) due to fear of swallowing and respiratory laryngeal motion and this remains the standard approach in many academic institutions. Local control (LC) rates with CL-RT have been excellent, however this treatment can carry significant toxicities include adverse voice and swallowing outcomes, along with increased long-term risk of cerebrovascular morbidity. A recent retrospective study reported improved voice quality and similar local control outcomes with focused vocal cord radiotherapy (VC-RT) compared to CL-RT. There is currently no prospective evidence on the safety of VC-RT. The primary objective of this Bayesian Phase II trial is to compare the LC of VC-RT to that of CL-RT in patients with T1N0 glottic SCC. METHODS One hundred and fifty-five patients with T1a-b N0 SCC of the true vocal cords that are n ot candidate or declined laser surgery, will be randomized in a 1:3 ratio the control arm (CL-RT) and the experimental arm (VC-RT). Randomisation will be stratified by tumor stage (T1a/T1b) and by site (each site will be allowed to select one preferred radiation dose regimen, to be used in both arms). CL-RT volumes will correspond to the conventional RT volumes, with the planning target volume extending from the top of thyroid cartilage lamina superiorly to the bottom of the cricoid inferiorly. VC-RT volumes will include the involved vocal cord(s) and a margin accounting for respiration and set-up uncertainty. The primary endpoint will be LC at 2-years, while secondary endpoints will include patient-reported outcomes (voice impairment, dysphagia and symptom burden), acute and late toxicity radiation-induced toxicity, overall survival, progression free survival, as well as an optional component of acoustic and objective measures of voice analysis using the Consensus Auditory-Perceptual Evaluation of Voice. DISCUSSION This study would constitute the first prospective evidence on the efficacy and safety of VC-RT in early glottic cancer. If positive, this study would result in the adoption of VC-RT as standard approach in early glottic cancer.

Could Primary Chemoradiotherapy in T2 Glottic Cancers Yield Results Comparable to Primary Radiotherapy in T1? Considerations from 531 German Early Stage Patients. Cancers (Basel) 2021; 13:cancers13071601. [PMID: 33807125 PMCID: PMC8037641 DOI: 10.3390/cancers13071601] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Revised: 03/25/2021] [Accepted: 03/26/2021] [Indexed: 02/07/2023] Open
Abstract
T1 glottic cancer is a highly treatable disease with local control (LC) rates over 90% by either primary radiotherapy (pRT) or transoral laser microsurgery (TLM). LC of T2 glottic cancers is 15 percent points poorer on average. However, salvage after pRT entails more than 50% total laryngectomy. Therefore, there is a need for enhanced LC. Altered fractionation regimens improved LC in T1 but not in T2. For this reason, for T2, alternative strategies must be considered. In a large observational cohort study including 531 early-stage laryngeal cancers, a small number of patients were treated with primary chemoradiotherapy (pCRT). In multivariable analysis, factors associated with significantly poorer outcomes included age, comorbidities, supraglottic localization, and T category. While there was a significant difference between pRT and surgery (HR 1.79; 95%-CI: 1.15-2.79), there was none between pCRT and surgery (HR 0.70; 95%-CI: 0.33-1.51). There is evidence from the literature that pCRT in early glottic cancers could yield results that surpass the limits so far experienced in radiotherapy alone with acceptable toxicity. Thus, prospective randomized studies with larger numbers of patients are warranted.

Abstract
INTRODUCTION Our purpose is to review the role radiotherapy (RT) in the treatment of glottic squamous cell carcinoma (SCC). METHODS A concise review of the pertinent literature. RESULTS RT cure rates are Tis- T1N0, 90% to 95%; T2N0, 70% to 80%; low-volume T3-T4a, 65% to 70%. Concomitant cisplatin is given for T3-T4a SCCs. Severe complications occur in 1% to 2% for Tis-T2N0 and 10% for T3-T4a SCCs. Patients with high-volume T3-T4 SCCs undergo total laryngectomy, neck dissection, and postoperative RT. Those with positive margins and/or extranodal extension receive concomitant cisplatin. The likelihood of local-regional control at 5 years is 85% to 90%. Severe complications occur in 5% to 10%. CONCLUSIONS RT is a good treatment option for patients with Tis-T2N0 and low-volume T3-T4a glottic SCCs. Patients with higher volume T3-T4 cancers are best treated with surgery and postoperative RT.

Abstract
The aim of the present study was to retrospectively investigate the risk factors of local failure for T1 glottic carcinoma irradiated with a prescription dose of 66 Gy. Between July 2006 and December 2017, 64 patients with T1 glottic squamous cell carcinoma treated with 66 Gy/33 fractions were analyzed for risk factors of local failure. The sex, age, performance status, T stage, overall treatment time, anterior commissure involvement, smoking status during/after treatment, histological tumor grade and pretreatment hemoglobin level were investigated. The maximum, mean and minimum doses, and the homogeneity index for the glottic larynx were calculated for dosimetric risk factors of local failure. The median follow-up duration was 51 months. Local failure was observed in 6 patients (9.5%). Among all risk factors, only the minimum dose to the glottic larynx was found to be significantly associated with local failure (P=0.025). The 5-year local control rates for a minimum dose to the glottic larynx of <65 and ≥65 Gy were 79 and 95%, respectively, with a statistically significant difference (P=0.015). No patients exhibited grade ≥3 late adverse effects. The minimum dose to the glottic larynx was the only factor significantly associated with local failure. Thus, local control of T1 glottic carcinoma may improve with a minimum dose of ≥65 Gy to the glottic larynx. In conclusion, radiotherapy with a minimum prescription dose of ≥65 Gy to the glottic larynx appears to be safe and achieves a high local control rate for T1 glottic carcinoma.

Abstract
A 60-year-old man was found unconscious at work, without any signs of trauma. At the site, he presented with tonic-clonic seizures, central facial palsy and eye deviation. A CT scan of the cerebrum did not find bleeding or thrombosis, but contrast enhancement at the superior sagittal sinus and pathological cervical lymph nodes. The MRI demonstrated multiple intracerebral metastases, while a supplementary fluoro-deoxy-glucose positron emission tomography scan revealed metastatic lesions above and below the diaphragm, without signs of a primary tumour. An ear, nose and throat examination found a small supraglottic tumour and cervical lymph node metastases. Following a multidisciplinary team discussion, biopsies from the duodenal mucosa and an inguinal lymph node were performed, showing squamous cell carcinoma with its origin in the head and neck. The patient was diagnosed with a T1N2cM1 supraglottic laryngeal cancer, receiving palliative whole brain radiation therapy but died 11 weeks after the debut of symptoms.

Cancers (Basel) 2020; 12:cancers12030732. [PMID: 32244899 PMCID: PMC7140062 DOI: 10.3390/cancers12030732] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 03/05/2020] [Accepted: 03/16/2020] [Indexed: 12/27/2022] Open
Abstract
For the treatment of early and locally advanced glottic laryngeal cancer, multiple strategies are available. These are pursued and supported by different levels of evidence, but also by national and institutional traditions. The purpose of this review article is to compare and discuss the current evidence supporting different loco-regional treatment approaches in early and locally advanced glottic laryngeal cancer. The focus is kept on randomized controlled trials, meta-analyses, and comparative retrospective studies including the treatment period within the last twenty years (≥ 1999) with at least one reported five-year oncologic and/or functional outcome measure. Based on the equipoise in oncologic and functional outcome after transoral laser surgery and radiotherapy, informed and shared decision-making with and not just about the patient poses a paramount importance for T1-2N0M0 glottic laryngeal cancer. For T3-4aN0-3M0 glottic laryngeal cancer, there is an equipoise regarding the partial/total laryngectomy and non-surgical modalities for T3 glottic laryngeal cancer. Patients with extensive and/or poorly functioning T4a laryngeal cancer should not be offered organ-preserving chemoradiotherapy with salvage surgery as a back-up plan, but total laryngectomy and adjuvant (chemo) radiation. The lack of high-level evidence comparing contemporary open or transoral robotic organ-preserving surgical and non-surgical modalities does not allow any concrete conclusions in terms of oncological and functional outcome. Unnecessary tri-modality treatments should be avoided. Instead of offering one-size-fits-all approaches and over-standardized rigid institutional strategies, patient-centered informed and shared decision-making should be favored.

Abstract
Background: This preliminary simulation study aimed to compare the dosimetric outcomes of
carotid arteries (CAs) and pharyngeal constrictor muscle (PCM) in patients
with T1N0M0 glottic carcinoma undergoing helical tomotherapy-intensity
modulated radiotherapy (HT-IMRT) and 3-dimensional conformal radiotherapy
(3D-CRT) plans. Methods: In addition to the clinical target volume (CTV) which was defined as the
entire larynx, the CAs and PCM of 11 glottic carcinoma patients were
delineated. The CTV was uniformly expanded 5 mm to create a planning target
volume (PTV) relative to the PCM and at a distance of 2 mm from the CA. The
dosimetric characteristics in HT-IMRT and lateral opposed fields-based
3D-CRT plans were analyzed. Results: Median D95%and V100% of PTV were significantly higher
in HT-IMRT (p < 0.001) compared to 3D-CRT. The right/left CA dosimetric
outcomes, including the mean doses (20.7/21.5 Gy versus 48.7/50.5 Gy),
Dmax (53.6/52.0 Gy versus 67.4/67.7 Gy), V30
(25.0/27.1% versus 77.6/80.3%), V40 (8.0/7.9% versus 74.6/71.9%),
and V50 (2.0/1.2% versus 70.0/71.6%) were also significantly
lower in HT-IMRT (p < 0.05), similar to the mean PCM doses (49.6 Gy
versus 62.6 Gy for 3D-CRT;p < 0.001), respectively. Conclusions: Our present results demonstrated the feasibility of simultaneous sparing of
the CAs and PCM in HT-IMRT- compared to 3D-CRT plans in glottic carcinoma
patients undergoing definitive radiotherapy.

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.

The prognostic value of anterior commissure involvement in T1 glottic cancer: A systematic review and meta-analysis. Laryngoscope 2019; 130:1932-1940. [PMID: 31721216 DOI: 10.1002/lary.28395] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 09/29/2019] [Accepted: 10/10/2019] [Indexed: 12/19/2022]
Abstract
OBJECTIVE The anterior commissure is considered a laryngeal subsite, but it is not taken into account in the current T-staging system. The impact of anterior commissure involvement (ACI) on the oncologic outcomes of T1 glottic tumors has not been well defined and remains controversial. The aim of this study was to assess the influence of ACI in the prognosis of T1 glottic tumors. METHODS A systematic review and meta-analysis of observational studies was performed by including studies published up to July 2019. Studies were selected if they had investigated the local control rate (LCR) at 5 years of clinical stage I (T1 and N0) glottic squamous cell carcinoma with and without ACI. The difference in LCR at 5 years between T1 glottic tumors without and with ACI was evaluated. RESULTS The meta-analysis showed that the difference in LCR at 5 years between T1 glottic tumors without and with ACI is 12% (95% confidence interval: 8%-16%, p < 0,0001, I2 = 34.81%). CONCLUSIONS Our study pointed out that the anterior commissure involvement is a negative prognostic factor in LCR at 5 years for T1 glottic tumors. Our results suggest the need to consider ACI in the T staging of glottic tumors. Laryngoscope, 130:1932-1940, 2020.

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
Background and Purpose: Larynx cancer represents one of the most frequently diagnosed head and neck malignancies, which is most often confined to the glottic area. The aim of this study was to report the oncological outcome and identify prognostic factors in early-stage glottic squamous cell carcinoma treated with radiotherapy. Material and Methods: Patients (n = 761) diagnosed and treated in 10 centers between 1990 and 2015 were retrospectively analyzed. Probabilities of loco-regional control (LRC) and overall survival (OS) were calculated and possible prognostic factors were analyzed using Cox proportional hazards models. Results: The median follow-up was 63 months (range: 2-243). Three hundred and sixty-four, 148 and 249 patients had cT1a, cT1b, and cT2 stage I-II disease, respectively. Five and 10-years LRC/OS rates in the whole cohort were 83/82% and 80/68%, respectively. Three patients developed distant recurrences. In univariate analysis, male sex (HR: 3.49; 95% CI: 1.47-11.37; p < 0.01), T2 vs. T1a (HR: 1.62; 95% CI: 1.08-2.43; p = 0.02) and anterior commissure involvement (ACI) (HR: 1.66; 95% CI: 1.38-2.45; p < 0.01) were associated with impaired LRC. In multivariate analysis, male sex (HR: 3.42; 95% CI: 1.44-11.17; p < 0.01) and ACI (HR: 1.51; 95% CI: 1.01-2.28; p = 0.047) remained poor prognostic factors. No relation of treatment technique and biologically equivalent dose (BED) to oncological outcome was identified except for higher BED10(L = 25; T = 1) yielding better LRC in T1a tumors (p = 0.04) in univariate analyses. Conclusion: Our results highlight the negative impact of ACI on tumor control. A less-expected finding was the impact of sex on tumor control. Further research is needed to validate its prognostic value and investigate any related biologic or behavioral factors, which may be modified to improve oncologic outcome.

Involvement of the Anterior Commissure in Early Glottic Cancer (Tis-T2): A Review of the Literature. Cancers (Basel) 2019; 11:cancers11091234.

Abstract
Background: The impact of the anterior commissure (AC) involvement on prognosis in laryngeal cancer remains a topic of discussion with inconsistent results in the literature. This review examines AC involvement as a prognostic factor in patients with early glottic cancer (Tis-T2) treated with radiotherapy or transoral laser microsurgery (TLM). Methods: A systematic literature search was performed. Due to the heterogeneity of the data, no meta-analysis was implemented. Weighted averages were calculated if the appropriate data were extractable. Results: Thirty-four studies on radiotherapy and 23 on TLM fit the inclusion criteria. The majority of studies for both radiotherapy (67.7%) and TLM (75.0%) did not report a significant impact on oncological outcomes. Weighted averages were slightly lower in patients with AC involvement. The two studies that applied a more detailed classification showed a significant impact on the amount of AC involvement. Conclusions: Binary variables (yes/no) for AC involvement lead to inconsistent results. Studies that use more detailed classifications of the AC show that there is a significant impact on the outcome. To further elucidate the role of the AC, detailed stratification of tumors involving the AC need to be investigated in further studies for both treatment modalities.

Abstract
PURPOSE Presentation of long-term results of radiation treatment in patients with T1 glottic cancer and evaluation of prognostic factors. METHODS We performed a retrospective analysis in a group of 569 patients with T1 squamous cell glottic carcinoma treated with radiotherapy at the Center of Oncology in Cracow between 1977 and 2007. In all, 503 (88%) patients presented with T1a stage disease and 66 (12%) with T1b. Anterior commissure infiltration was present in 179 (31%) patients. Average hemoglobin level prior to therapy was 13.9 g/dl. Using the body mass index (BMI), 114 (20%) patients were underweight, and 91 (16%) were overweight. Median time between collecting tumor specimen and beginning of radiotherapy was 56 days (range 14-145 days). Treatment regimen was normofractionated with single fraction ≤2 Gy in 102 (18%) and hypofractionated in 467 (82%) patients. RESULTS The 5‑ and 10-year overall survival (OS), disease-specific survival (DSS) and local control (LC) rates were 85 and 68%, 88 and 86%, 89 and 87%, respectively. Multivariate analysis showed that tobacco smoking, low hemoglobin level (<13 g/dl), anterior commissure infiltration, fraction dose ≤2 Gy and time from collecting specimen to beginning of therapy longer than 30 days had negative impact on LC and DSS. Patients' age over 60 years, worse performance status and malnutrition (BMI <18.5) had negative impacts on OS. CONCLUSIONS Radiotherapy is a highly effective treatment method in patients with T1N0M0 glottic cancer. LC and DSS may be improved following hypofractionation, smoking cessation, and shortening of waiting-time until start of treatment. OS was mainly influenced by nutritional and performance status.

Abstract
PURPOSE The aim of this study was to perform a comparison between robust optimization and planning target volume (PTV)-based optimization plans using volumetric modulated arc-therapy (VMAT) by evaluating perturbed doses induced by localization offsets for setup uncertainties in larynx cancer radiation therapy. METHODS Ten patients with early-stage (T1-2N0) glottis carcinoma were selected. The clinical target volume (CTV), carotid arteries, and spinal cord were contoured by a radiation oncologist. PTV-based and robust optimization plans were normalized at D50% to the PTV and D98% to the CTV, respectively. Both optimization plans were evaluated using perturbed doses by specifying user defined shifted values from the isocenter. CTV dose (D98%, D50%, and D2%), homogeneity index (HI) and conformity index (CI95%, CI80%, and CI50%), as well as doses to the carotid arteries and spinal cord were compared between PTV-based and robust optimization plans. RESULTS The robust optimization plans exhibited superior CTV coverage and a reduced dose to the carotid arteries compared to the PTV-based optimization plans (p < 0.05). HI, CI95% and the dose to the spinal cord did not significantly differ between the PTV-based and robust optimization plans (p > 0.05). The robust optimization plans showed better CI80% and CI50% compared to the PTV-based optimization plans (p < 0.05). Plan perturbed evaluations showed that the robust optimization plan has small variations in the doses to the CTV, carotid arteries, and spinal cord compared to the PTV-based optimization plan. CONCLUSIONS The robust optimization plan may be a suitable treatment method in radiotherapy for larynx cancer patient.

Abstract
Aims and background Radiotherapy has remarkable success rates for the cure of patients affected by glottic carcinoma; local control rates are similar to surgery with lower morbidity and better functional results. Our aim was to determine local-regional control rates, overall survival, second cancer incidence, acute-late toxicity and prognostic factors in our series of T1 glottic cancer patients with radiation doses of 60 to 66 Gy. Functional results were not sufficient for statistical analysis. Methods and study design A retrospective study was carried out of all T1N0 glottic carcinomas treated with radiation therapy between 1996 and 2006. To be eligible, patients had to have newly diagnosed cancer and had to be treated with a curative intent by radiation therapy alone. Ninety-eight patients satisfied the eligibility requirements: 85 patients had T1a disease; 13 patients were staged as T1b. Treatment was performed for all cases with a 6 megavoltage linear accelerator. The total dose prescribed varied from 60 to 66 Gy: 2 Gy/fraction, 1 fraction/day, 5 fractions/week. During treatment, a weekly clinical evaluation was performed; endoscopic examination was performed once every two weeks. After the treatment, a clinical, endoscopic and radiological follow-up was performed every three months for the first two years, every 6 months till the fifth year, and then once a year. Results With a median follow-up of 41.5 months (range, 10-132; mean, 56.8), we registered 12 cases of local failures; 8 of them were successfully treated with salvage surgery (median time to relapse, 3–48 months). The local relapse rate was 12.2%, and disease-specific survival, taking into account salvage surgery, was 6%. Thirty-four deaths were registered: 2 for local progression, 2 for distant metastasis, 4 for a new primary cancer, and 26 for non-neoplastic causes. Five- and 10-year overall survival were respectively 85.8% and 69.4%. Four cases of lung cancer were detected in the upper aerodigestive tract in our series. In terms of acute-late toxicity, no grade 3-4 dermatitis, dysphagia or hoarseness occurred. Mild dermatitis and arythenoid edema were the most common causes of toxicity. Only one patient did not complete the treatment (60 Gy instead of the planned 66 Gy). Conclusions Our series confirmed the primary role of radiation therapy for the cure of T1N0 glottic cancer. Outcomes were good in terms of local-regional control as well as overall toxicity. Radiation therapy can be offered to T1 glottic cancer patients as a valid alternative to surgery, with high rates of functional preservation.

Abstract
Aims and background In 2006 a survey was performed to define the resources available in Italy for the provision of radiotherapy services to head and neck cancer patients. This was the first initiative of the newly founded Head and Neck Group of the Italian Association for Radiation Oncology. Methods A questionnaire was sent to all 138 radiotherapy centers active in the country. Items investigated included total numbers of head and neck cancer patients treated per year, waiting time before the start of treatment, general technical issues, and integration with surgery and chemotherapy. Results Sixty-nine questionnaires were returned (50% response rate). The total number of patients treated was 4,670, averaging 68 cases per center. The larynx was the primary site most frequently involved. Average waiting time was 30 days and 47 days for nonresected and postoperative cases, respectively. The combination of chemotherapy and radiotherapy was delivered to nonresected and resected patients in 96% and 54% of centers, respectively. Survey response rates, waiting time, and the use of organ preservation protocols were the issues showing more variations across the country. Conclusions This survey provides important data on radiotherapy resources available for head and neck cancer patients in Italy. The evidence of significant differences across the country concerning several relevant issues and the potential for cooperative clinical efforts in this relatively rare group of diseases urge the Group to plan further initiatives.

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

Abstract
Early laryngeal, especially glottic, cancer is a good candidate for radiotherapy because obvious early symptoms (e.g. hoarseness) make earlier treatment possible and with highly successful localized control. This type of cancer is also a good model for exploring the basic principles of radiation oncology and several key findings (e.g. dose, fractionation, field size, patient fixation, and overall treatment time) have been noted. For example, unintended poor outcomes have been reported during transition from 60Cobalt to linear accelerator installation in the 1960s, with usage of higher energy photons causing poor dose distribution. In addition, shell fixation made precise dose delivery possible, but simultaneously elevated toxicity if a larger treatment field was necessary. Of particular interest to the radiation therapy community was altered fractionation gain as a way to improve local tumor control and survival rate. Unfortunately, this interest ceased with advancements in chemotherapeutic agents because alternate fractionation could not improve outcomes in chemoradiotherapy settings. At present, no form of acceleration can potentially compensate fully for the lack of concurrent chemotherapy. In addition, the substantial workload associated with this technique made it difficult to add extra fractionation routinely in busy clinical hospitals. Hypofractionation, on the other hand, uses a larger single fractionation dose (2-3 Gy), making it a reasonable and attractive option for T1-T2 early glottic cancer because it can improve local control without the additional workload. Recently, Japan Clinical Oncology Group study 0701 reprised its role in early T1-T2 glottic cancer research, demonstrating that this strategy could be an optional standard therapy. Herein, we review radiotherapy history from 60Cobalt to modern linear accelerator, with special focus on the role of alternate fractionation.

Abstract
INTRODUCTION To assess laryngeal motion in early glottic cancer in order to determine safe margins for partial larynx volumetric modulated arc therapy (PL-VMAT), and to quantify dosimetric advantages of PL-VMAT. METHODS This prospective study included T1-2N0 glottic cancers treated with whole larynx VMAT (WL-VMAT). Pre- and mid-treatment 4D-computed tomography (4D-CT) and dynamic magnetic resonance imaging (MRI) allowed for assessment of larynx swallowing and respiratory motion. For 10 patients with lateralized lesions, PL-VMAT plans were calculated using margins derived from 4D-CT analysis. RESULTS Twenty patients were accrued from 2014 to 2016. Mean amplitude of larynx swallowing excursion was 23 mm and 6 mm in the superior and anterior directions, respectively. Mean respiratory motion reached 4 mm and 2 mm in superior-inferior and antero-posterior directions, respectively. Pre-treatment 4D-CT analysis identified one patient with planning CT acquired during swallowing. Mid-treatment 4D-CT revealed larynx shift relative to vertebrae in 30% of cases. PL-VMAT allowed for significant reduction of mean doses to ipsilateral carotid, contralateral carotid, thyroid gland, contralateral arytenoid and larynx. Using 8 mm internal margin for PL-VMAT, swallowing resulted in clinical target volume excursion beyond 95% isodose line during ≤1.5% of total treatment time in all patients. CONCLUSION Although swallowing motion is rare, rapid and easily suppressed by patients, there is a risk of systematic miss-targeting if planning CT is acquired during swallowing. Larynx position shift relative to vertebrae occurs in 1/3 of patients over the course of radiotherapy. With soft-tissue image guidance and margins accounting for respiratory motion, PL-VMAT allows safe reduction of dose to organs at risk.

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
BACKGROUND The optimal treatment strategy for stage I-II glottic squamous cell carcinoma (SCC) is not well-defined. This study analyzed treatment results and prognostic factors. PATIENTS AND METHODS This is a single-institution retrospective analysis of 244 patients with T1-2 glottic SCC who underwent normofractionated radiotherapy (RT) and/or surgery between 1990 and 2013. The primary endpoint was relapse-free survival (RFS). RESULTS Median age was 65 years (range: 36-92 years), the majority (82%) having stage I disease. Definitive RT was used in 82% (median dose: 68 Gy, 2 Gy per fraction). Median follow-up was 59 months. The 5‑year RFS rates were 83 and 75% (p = 0.05) for stage I and 62 and 50% (p = 0.47) for stage II in the RT and surgery groups, respectively. Multivariate analyses indicate T1 vs. T2 and RT vs. surgery as independent prognostic factors for RFS, with hazard ratios of 0.38 (95% confidence interval, CI: 0.21-0.72) and 0.53 (95% CI: 0.30-0.99), respectively (p < 0.05). The 5‑year overall and cause-specific survival rates in the whole cohort were 92 and 96%, respectively, with no significant differences between treatment groups. Anterior commissure involvement was neither a prognostic nor a predictive factor. The incidence of secondary malignancies was not significantly different between patients treated with and without RT (22 vs. 9% at 10 years, respectively, p = 0.18). CONCLUSION Despite a possible selection bias, our series demonstrates improved RFS with RT over surgery in stage I glottic SCC.

Relationship of medial versus superior vocal-cord location of T1 squamous cell carcinoma with tumor recurrence. Am J Otolaryngol 2017; 38:316-320. [PMID: 28169008 DOI: 10.1016/j.amjoto.2017.01.033] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Revised: 01/26/2017] [Accepted: 01/31/2017] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To determine if the clinical behavior of T1 glottic squamous cell carcinoma varies by its location on the medial free edge or upper aspect of the vocal cords. STUDY DESIGN Retrospective cohort. SETTING Single tertiary university-affiliated medical center. SUBJECTS AND METHODS Clinical, treatment, and outcome data were collected for 104 patients with T1N0M0 glottic squamous cell carcinoma who were treated and followed at our center in 1995-2013. Findings were compared between those with a tumor on the medial (n=60, 57.7%) or superior (n=44, 42.3%) aspect of the cords. RESULTS Mean follow-up time was 4.15years. No between-group differences were found in demographic or risk factors. There was a significant association of anterior commissure involvement with disease recurrence (P=0.0012) and of superior (vs medial) location with higher rates of anterior commissure involvement (P<0.001) and recurrence (P=0.01) and shorter time to recurrence (P<0.001). CONCLUSIONS T1 squamous cell carcinomas on the superior aspect of the vocal cords have a poorer prognosis than medial tumors and should be closely monitored for recurrence.

[PMID: 28721883 DOI: 10.1016/j.ijrobp.2017.03.050] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 12/16/2016] [Accepted: 03/28/2017] [Indexed: 11/18/2022]
Abstract
PURPOSE To characterize practice patterns, including temporal trends, in fractionation schedules among patients in the United States undergoing definitive radiation therapy for early-stage glottic cancer and to compare overall survival outcomes between fractionation schedules. METHODS AND MATERIALS We queried the National Cancer Database for patients with TisN0M0, T1N0M0, or T2N0M0 squamous cell carcinoma of the glottic larynx diagnosed between 2004 and 2012 and undergoing definitive radiation therapy. Dose per fraction was calculated to define cohorts undergoing conventional fractionation (CFxn) and hypofractionation (HFxn). Logistic regression was performed to identify predictors of receiving HFxn, and Cox regression was used to determine predictors of death. One-to-one propensity score matching was then used to compare survival between fractionation schedules. RESULTS The study included 10,539 patients, with 6576 undergoing CFxn and 3963 undergoing HFxn. Patients with T1 disease comprised a majority of each cohort. Use of HFxn increased significantly over the period studied (P<.001), but even in the final year, nearly one-half of patients continued to receive CFxn. Receipt of HFxn was also independently associated with higher income and facility types other than community cancer programs on logistic regression. On multivariate Cox regression, HFxn was associated with improved survival (hazard ratio [HR] for death, 0.90; 95% confidence interval [CI], 0.83-0.97; P=.008), a finding redemonstrated on univariate Cox regression among a well-matched cohort after propensity score matching (HR, 0.88; 95% CI, 0.80-0.96; P=.003). Subgroup Cox multivariate analysis demonstrated a significant survival advantage with HFxn among patients with T1 disease (HR, 0.90; 95% CI, 0.81-0.99; P=.042) but a nonsignificant benefit among those with Tis (HR, 0.86; 95% CI, 0.57-1.30; P=.472) or T2 (HR, 0.88; 95% CI, 0.76-1.02; P=.099) disease. CONCLUSIONS Use of HFxn is increasing and is associated with improved survival over CFxn. Our findings support the broadened use of HFxn for patients with early-stage glottic cancer undergoing definitive radiation therapy.

Abstract
Purpose The purpose of this study was to compare the treatment outcomes of definitive radiotherapy (RT) with cordectomy in patients with early glottic cancer. Materials and Methods A total of 165 patients who were diagnosedwith T1/2 squamous cell carcinoma of the glottic larynx between January 2006 and December 2012 were retrospectively analyzed. A total of 112 patients received RT and 53 patients received cordectomy. Local control (LC), disease-free survival (DFS), overall survival (OS), and larynx preservation rates after RT and cordectomy were investigated. Results The median follow-up period was 77.7 months (range, 10.7 to 127.0 months). The 3- and 5-year LC rates were 91.9% and 89.9%, respectively, for the RT group, and 82.8% and 73.2%, respectively, for the cordectomy group (p=0.006). The 3- and 5-year DFS rates were 87.5% and 83.7%, respectively, for the RT group and 79.2% and 68.0%, respectively, for the cordectomy group (p=0.046). No significant differences were identified in the 5-year OS (92.8% vs. 90.6%, p=0.713) or larynx preservation rates (98.2% vs. 97.2%, p=0.831) between groups. The major failure pattern was local failure (n=26), followed by regional (n=3) and distant failure (n=2). Multivariate analysis of LC showed that T2 stage (p=0.012) and receiving cordectomy as initial treatment (p=0.001) were significantly associated with poorer LC. Conclusion RT resulted in higher rates of LC and DFS compared to cordectomy for early glottic cancer. Treatment with radiotherapy is feasible and should be encouraged for both T1 and T2 glottic cancer.

[PMID: 27865377 DOI: 10.1016/j.oraloncology.2016.10.013] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 10/08/2016] [Accepted: 10/16/2016] [Indexed: 01/04/2023]
Abstract
BACKGROUND Radiotherapy is one of the main treatment modalities for early-stage glottic carcinoma. Unfortunately, local failure may occur in a group of cases with T1-T2 glottic carcinoma. This meta-analysis sought to determine risk factors for radiation failure in patients with early-stage glottic carcinoma. METHODS A systematic and comprehensive search was performed for related studies published between 1995 and 2014. The primary end-point was 5-year local control. Data extraction and analysis were performed using the software STATA/SE 13.1 for Windows. RESULTS Twenty-seven studies were eligible. A higher risk of radiation failure was demonstrated in male patients [relative risk (RR): 0.927, p<0.001] and those with low hemoglobin level (RR: 0.891, p<0.001) with a high agreement between studies (I-squared=0.0%). Moreover, T2 tumors (RR: 0.795, p<0.001), tumors with anterior commissure involvement (RR: 0.904, p<0.001), tobacco use during/after therapy (RR: 0.824, p<0.001), and "bulky" tumors (RR: 1.270, p<0.001] or tumors bigger in size (RR: 1.332, p<0.001]. Poorly differentiated tumors had a questionable risk of local failure, although a moderate to high interstudy heterogeneity was determined. A statistically significant contribution was not detected for age, presence of comorbidity, alcohol use or subglottic extension. CONCLUSION This is the first meta-analysis which assessed the potential risk factors for radiation failure in patients with early-stage glottic carcinoma. Gender and pretreatment hemoglobin level are major influential factors associated with radiation failure in patients with early-stage glottic carcinoma. However, prospective, randomized clinical trials may permit better stratification of their relative contributions, and those who may benefit more from upfront surgery.

Abstract
OBJECTIVES/HYPOTHESIS The purpose of this study was to report the outcomes of a retrospective consecutive cohort study of patients with T1N0M0 glottic carcinoma treated with 4-MV or 6-MV radiotherapy. STUDY DESIGN Retrospective case-control study. METHODS This was a retrospective review of all patients with T1N0M0 glottic carcinoma treated with radiotherapy between January 2000 and December 2012 in the Department of Radiation Oncology at National Cancer Center Singapore. A total of 124 patients were included. Clinical endpoints of interest were: local control (LC), overall survival (OS), and disease-specific survival (DSS). Other prognostic factors for LC were also analyzed: age, gender, smoking status, T substage, dose fraction, field size, anterior commissure involvement, total dose, and overall treatment time. RESULTS Six-megavolt photon radiotherapy was used in 73 patients and 4-MV photon radiotherapy in 51 patients. Median follow-up was 4.9 years. The 5-year LC and OS were as follows: 4 MV, 91.6% and 83.4%; 6 MV, 88.8% and 82.8%; and the 5-year LC, OS, and DSS for all patients were 90.4%, 83.3%, and 98.3%. There was no significant difference in LR and OS between 4-MV and 6-MV radiotherapy (P = .92, P = .16, respectively). In the univariate analysis of LC, none of the prognostic factors was statistically significant. Twenty patients (23%) developed second primary cancers, the majority in the lungs. CONCLUSIONS Six-megavolt photon radiotherapy yields comparable results to 4-MV photons. Bolus and computed tomographic simulation are useful to ensure adequate dose coverage of target volume. Follow-up postradiotherapy should incorporate chest imaging, smoking cessation advice, and thyroid function test. LEVEL OF EVIDENCE 4 Laryngoscope, 127:1061-1067, 2017.

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
AbstractObjective:The tumour–node–metastasis staging system has a dynamic structure that is continuously being updated as scientific data develops. This review discusses some suggested revisions on tumour–node–metastasis staging of human papillomavirus negative upper aerodigestive tract cancers.Methods:The seventh edition of The American Joint Committee on Cancer Staging Manual was reviewed and important issues that could be considered for revision were identified and discussed.Results:According to our assessment of the oncological outcomes of previous studies, the following factors should be considered for revision: anterior commissure involvement and subglottic extension in laryngeal cancers; underlying bone involvement in hard palate and upper alveolar ridge cancers; tumour thickness in oral cancers; and extracapsular spread and carotid artery involvement in neck metastases.Conclusion:Sufficient data on the prognostic importance of these issues have been reported. Suggested revisions in line with current knowledge on the clinical behaviour of upper aerodigestive tract cancers would improve the relevancy of staging.

Abstract
OBJECTIVE Supracricoid laryngectomy with cricohyoidoepiglottopexy has been known to be able to cope with tumor excisions with minimal margins. Extended resection may result in a limited margin and may impair the prognosis. We conducted a clinicopathologic analysis of local recurrence in supracricoid laryngectomy with cricohyoidoepiglottopexy patients. METHODS Between 1997 and 2013, 100 patients with glottic cancers underwent supracricoid laryngectomy with cricohyoidoepiglottopexy. The clinicopathologic findings were evaluated. We also analyzed: (i) cancer-specific and overall survival rates, (ii) the correlation between locoregional recurrence and overall survival, (iii) T staging and larynx preservation rates and (iv) previous radiation history and larynx preservation rates. RESULTS Local recurrence was recognized in eight of the 100 patients (8%); all were initially staged as T3 or T4. Recurrence was identified in the submucosal regions of the ipsilateral arytenoid and/or infraglottis. Six patients were salvaged by completion total laryngectomy except two. Cancer-specific survival at 5 years was 93%; overall survival at 5 years was 89%. There was no significant difference between overall survival and locoregional recurrence. There was a significant difference between larynx preservation in T1-2 and T3-4 patients. There was no significant difference between larynx preservation and the previous radiation therapy status. CONCLUSIONS Our experience convinced us of the clinical potential of supracricoid laryngectomy with cricohyoidoepiglottopexy as one of the effective options for functional larynx preservation. Supracricoid laryngectomy with cricohyoidoepiglottopexy is the most suitable for unfavorable T2 and T3a cases and is applicable for appropriately selected radiation-failed patients. Thorough pre-operative evaluation, proper surgical techniques and careful follow-up are prerequisites for the success of supracricoid laryngectomy with cricohyoidoepiglottopexy.

Abstract
BACKGROUND Although intensity-modulated radiotherapy (IMRT) is a standard of care for many head and neck cancers, its use for carotid-sparing (CS) therapy in early-stage laryngeal carcinoma is controversial. METHODS 330 consecutive patients with early-stage laryngeal carcinoma were treated from 1/1989 to 5/2011, including 282 conventional radiotherapy (CRT) and 48 CS-IMRT patients. The median follow-up was 43 (CS-IMRT) and 66 (CRT) months. RESULTS There was no difference in local failure rates comparing patients undergoing CS-IMRT with CRT, with 3-year local control rates of 88% vs. 89%, respectively (p=0.938). Using a 1cm circumferential margin, the average dose to the left and right carotid arteries was 48.3 and 47.9 Gy, respectively. 88% of locoregional recurrences involved the ipsilateral true vocal cord, including all local recurrences in the IMRT group. CONCLUSIONS These results warrant further prospective evaluation of CS-IMRT for early-stage glottic larynx cancer.

Abstract
BACKGROUND The purpose of this study was to acquire nationwide data on the management and outcome of laryngeal squamous cell carcinoma (SCC) in Finnish university hospitals over a 5-year posttreatment follow-up. METHODS All records of patients diagnosed and treated for primary laryngeal SCC during 2001 to 2005 were reviewed. RESULTS Three hundred sixty-six patients with laryngeal cancer were identified, 360 of whom had laryngeal SCC. Three hundred forty-two patients with laryngeal SCC (95%) were treated with curative intent. Five-year disease-specific survival (DSS) for T1a, T1b, T2, T3, and T4 glottic SCC was 100%, 95%, 78%, 79%, and 53%, respectively. The corresponding figures for T1 to T4 supraglottic SCC were 68%, 54%, 72%, and 59%. CONCLUSION Results of this nationwide study give a general overview of the outcome of unselected patients treated with unified guidelines. Patients with T2 tumors, usually treated with radiotherapy (RT), had a worse prognosis than expected. This patient group warrants further investigation and possibly treatment intensification.

Abstract
The clinical material consists of 217 patients with squamous cell carcinoma in supraglottic and glottic larynx in clinical stage T1-3N0M0 irradiated radically in Warsaw Oncology Centre in 1995-1998. All patients were treated with Co-60, according to two schedules of fractionation, with maintenance of the consistent therapeutic protocol. The same team of doctors worked on the treatment of patients and on the follow-up as well. The clinical material is a part of a three-phased clinical trial KBN 0295. In the course of observation, the progression of cancer was not observed in 157 patients, among whom, 66% were treated conventionally and 79% with accelerated fractionation method. 60 cases of loco-regional recurrences were noted, among which 55 were regional. The majority of failure cases was observed until the 30(th) of the month after the radiotherapy ended. In conventional fractionation treatment, recurrences in T1 were 8/31 (26%), in T2 22/59 (37%) and in T3 8/20 (40%). In patients treated with AF, recurrences were T1 5/39 (13%), T2 15/55 (27%) and T3 2/13 (15%) respectively. The percentage of primary site tumour recurrences for each localization and kind of treatment was analysed. In CF 28/78 (37%) of glottic tumour recurrences and 10/34 (29%) of supraglottic tumour, recurrences were observed. In AF, 12/71 (17%) and 10/36 (28%) were observed respectively. In 48 cases salvage surgery was used, and 12 patients were not qualified because of tumour massive progression or because they refused to have a surgery. Among 34 cases (16%) of the second primary tumour or distant methastases, 25 were observed with glottic cancer, among which 23 were observed in early stages, and 9 cases with supraglottic cancer, among which, 6 showed early stage of tumour. In only 3 cases out of all the patients, distant methastases were confirmed in histopatology examination. The main cause of failure in larynx cancer patients in stage T1 is that 3N0M0 are local recurrences. Second primary or distant methastases constitute 16% of the patients in this paper.

Is elective neck dissection necessary in cases of laryngeal recurrence after previous radiotherapy for early glottic cancer? The Journal of Laryngology & Otology 2014; 128:1089-94.

Abstract
OBJECTIVES To assess the clinical utility of elective neck dissection in node-negative recurrent laryngeal carcinoma after curative radiotherapy for initial early glottic cancer. METHODS A retrospective review was undertaken of 110 consecutive early glottic cancer patients who developed laryngeal recurrence after radiotherapy (34 recurrent T1, 36 recurrent T2, 29 recurrent T3 and 11 recurrent T4a) and received salvage laryngeal surgery between 1995 and 2005. RESULTS Six patients presented with laryngeal and neck recurrence and underwent salvage laryngectomy with therapeutic neck dissection, 97 patients with recurrent node-negative tumours underwent salvage laryngeal surgery without neck dissection and only 7 underwent elective neck dissection. No occult positive lymph nodes were documented in neck dissection specimens. During follow up, only three patients with neck failure were recorded, all in the group without neck dissection. There was no significant association between the irradiation field (larynx plus neck vs larynx) and the development of regional failure. A higher rate of post-operative pharyngocutaneous fistula development occurred in the neck dissection group than in the group without neck dissection (57.2 per cent vs. 13.4 per cent, p = 0.01). Multivariate logistic regression analysis showed that early (recurrent tumour-positive, node-positive) or delayed (recurrent tumour-positive, node-negative) neck relapse was not significantly related to the stage of the initial tumour or the recurrent tumour. An age of less than 60 years was significantly associated with early neck failure (recurrent tumour-positive, node-positive). CONCLUSION Owing to the low occult neck disease rate and high post-operative fistula rate, elective neck dissection is not recommended for recurrent node-negative laryngeal tumours after radiation therapy if the initial tumour was an early glottic cancer.

Abstract
CONCLUSION Frontovertical partial laryngectomy is useful for treatment of T1 and T2 glottic squamous cell carcinoma with anterior commissure involvement. OBJECTIVE To evaluate the efficiency of frontovertical partial laryngectomy for T1 and T2 glottic carcinoma with anterior commissure involvement. METHODS This was a retrospective review of 58 cases of glottic squamous cell carcinoma with anterior commissure involvement (T1, n = 28; T2, n = 30) that were treated by frontovertical partial laryngectomy between August 2000 and August 2010. RESULTS Postoperative pathology reports confirmed negative tumor margins in every case. All patients were followed postoperatively, with a median follow-up interval of 55 months. Three patients had local recurrence; there were no patients who had cervical or distant metastases. The 3-year local control rate was 94% according to life tables curves. There were no reports of laryngostenosis or dysphagia in any patients, and mean Voice Handicap Index (VHI) questionnaire scores were 32.9.
