Survival Outcomes in T3 Laryngeal Cancers: Primary Total Laryngectomy vs. Concurrent Chemoradiation or Radiation Therapy-A Meta-Analysis. Biomedicines 2023; 11:2128. [PMID: 37626625 PMCID: PMC10452463 DOI: 10.3390/biomedicines11082128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 07/22/2023] [Accepted: 07/25/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND The management of cT3 laryngeal cancers remains controversial, with studies recommending surgical or non-surgical approaches. Despite the many papers that have been published on the subject, there is a lack of studies showing which treatment has better results in terms of survival. OBJECTIVE To determine the difference in survival outcomes following total laryngectomy (TL), concurrent chemoradiation (CRT) or radiation therapy (RT) alone in T3 laryngeal cancers. METHODS Search of PubMed, Scopus, and Google Scholar databases from 1995 to 2023 employing specific keywords and Boolean operators to retrieve relevant articles. Statistical analysis was conducted using a random-effects model, and heterogeneity was evaluated using the Q-test and I2 statistic. Funnel plot asymmetry was assessed using rank correlation and regression tests. RESULTS The qualitative data synthesis comprised 10,940 patients from 16 included studies. TL was performed in 2149 (19.4%), CRT in 6723 (61.5%), RT in 295 (2.7%), while non-surgical treatment was not specified in 1773 (16.2%) patients. The pooled 2-year overall survival (OS) rates were TL = 73%, CRT = 74.7%, RT = 57.9%, 3-year OS rates were TL = 64.3%, CRT = 62.9%, RT = 52.4%, and 5-year OS rates were TL = 54.2%, CRT = 52.7%, RT = 40.8%. There was a significant heterogeneity in the included studies. There was no statistically significant difference in 2-year OS (logOR= -0.88 (95% confidence interval (CI): -1.99 to 0.23), p = 0.12), 3-year OS (logOR = -0.6 (95% CI: -1.34 to 0.15), p = 0.11), and 5-year OS (logOR = -0.54 (95% CI: -1.29 to 0.21), p = 0.16) between TL and CRT. Instead, there was significant difference in 2-year OS (logOR= -1.2383 (95% CI: -2.1679 to -0.3087), p = 0.009), 3-year OS (-1.1262 (95% CI: -1.6166 to -0.6358), p < 0.001), and 5-year OS (-0.99 (95% CI: -1.44 to -0.53)), p < 0.001) between TL and RT alone. CONCLUSIONS AND SIGNIFICANCE TL followed with adjuvant (chemo)radiation on indication and CRT with salvage surgery in reserve appear to have similar OS outcomes. Both resulted in better OS outcomes compared to RT alone in the treatment of T3 laryngeal cancers. If patients are unfit for chemotherapy, making CRT impossible, surgery may become the choice of treatment.

Abstract
BACKGROUND This study aimed to create a nomogram for postoperative prediction of the risk of recurrence in laryngeal squamous cell carcinoma patients who received laryngectomy alone and to assess indications for postoperative adjuvant treatments (POAT). METHODS A retrospective analysis of 1571 newly diagnosed laryngeal carcinoma patients was conducted. Those patients were divided into two groups-the development cohort (n = 1102) and the validation cohort (n = 469). Patients were classified into three subgroups according to their individual points calculated from the nomogram. The efficiency of POAT was examined among various subgroups. RESULTS Five variables, including pT classification, pN classification, surgical margin, tumor differentiation, and primary location, were included in the nomogram. The C-index was 0.753 in development cohort and 0.744 in validation cohort. Patients were classified into three subgroups with incremental risks of recurrence. In the high-risk group, patients receiving POAT showed significantly better recurrence-free survival (RFS) than did those receiving surgery alone, while POAT was not significantly associated with RFS in either the low- or moderate-risk groups. CONCLUSIONS The risk of tumor recurrence in patients with laryngeal carcinoma was quantified by our newly constructed nomogram. Patients categorized as high-risk were found to benefit from POAT in RFS.

Abstract
Background Hypopharyngeal and laryngeal neoplasms are both fatal and hard to catch in early stages. Yet which treatment is the most efficacious one still remain unanswered. This network meta-analysis (NMA) was conducted to investigate effectiveness of six therapies being utilized in clinical practice nowadays. Methods PubMed and Embase were retrieved to synthesize data. Direct and indirect evidence was combined to compare efficacy of treatments. A relative ranking of the six regimens was calculated by the surface under the curve ranking area (SUCRA). Results A total of 28 trials with 9109 patients were included in our NMA. Five endpoints investigated included 3/5-year overall survival (3/5-OS), 3/5-year disease free survival (3/5-DFS) and 5-year overall survival rate (5-OSR). In terms of all efficacy outcomes, radiotherapy combined with surgery (RT + S) proved to be better than other therapies while radiotherapy (RT) alone also performed well. Induction chemoradiotherapy (ICRT) was the best regarding 3-DFS (SUCRA = 0.846) while current chemoradiotherapy (CCRT) ranked first in 5-DFS (SUCRA = 0.933) according to SUCRA results. No significant differences were demonstrated in 5-DFS and 5-OSR as shown in the results of NMA. Conclusions RT combined with surgery turned out to be optimal therapy of all the outcomes while the efficacy of RT was relatively poorer in the treatment of patients with larynx stage III-IV and hypopharynx stage II-IV. Also, the good performance of CCRT and ICRT in terms of DFS made them as secondary recommended therapies. There is no significant difference between surgery and transoral laser microsurgery (TLM) alone.

Abstract
BACKGROUND Studies have shown mixed results on the role of postoperative adjuvant radiotherapy (PORT) in surgically managed locally advanced laryngeal cancer. OBJECTIVES The aim of this study is to review and investigate the role of PORT in patients with locally advanced laryngeal cancer using meta-analysis. MATERIALS AND METHODS Relevant studies were searched using PubMed and eligible information has been extracted. Then, meta-analysis of hazard ratio (HR) was performed to evaluate the role of PORT in locally advanced laryngeal cancer. RESULTS This meta-analysis included 7 published studies containing 2007 patients. For overall survival (OS), patients of locally advanced laryngeal cancer who were treated with PORT have a combined hazard ratio (HR) of 0.67 with 95%CI (0.56, 0.79), compared to those who were not treated with PORT, which was significantly associated with better survival. PORT was also associated with a better disease-free survival (DFS) and local control rate (LCR) in patients with locally advanced laryngeal cancer. The pooled HR and 95%CI for DFS and LCR were 0.72 (0.53, 0.99) and 0.29 (0.09, 0.99), respectively. CONCLUSIONS AND SIGNIFICANCE This study suggested that PORT could improve the survival of patients with surgically managed locally advanced laryngeal cancer.

Abstract
BACKGROUND We aimed to provide a pooled analysis of controlled trials comparing long-term survival after primary laryngectomy and primary organ preservation methods in patients with T3-4 laryngeal cancer. METHODS We performed random-effects meta-analyses on overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS), and locoregional control (LRC). RESULTS Fifteen studies met the selection criteria including 6288 patients (2696 patients who underwent primary laryngectomy and 3592 patients who underwent primary nonsurgical organ preservation therapy). There was a significant difference between the groups with respect to OS (HR 0.71, 95% CI 0.57-0.89, P = .003). However, a subgroup analysis found OS was not significantly worse for patients with T3 laryngeal cancer who received primary organ preservation compared with patients who underwent primary laryngectomy (HR 0.96, 95% CI 0.45-2.03, P = .91). There was no significant difference for DFS (HR 0.63, 95% CI 0.39-1.04, P = .07) in two groups. Patients with laryngeal cancer who underwent primary laryngectomy had a better DSS (HR 0.47, 95% CI 0.25-0.88, P = .02) and LRC (HR 0.56, 95% CI 0.390.80, P = .001) than patients who underwent primary nonsurgical organ preservation therapy. CONCLUSION Our results support total laryngectomy for patients with T4 laryngeal cancer and show that primary organ preservation for laryngeal cancer has no advantage and also did not decrease the rate of OS in patients with T3 laryngeal cancer when compared with primary total laryngectomy.

Abstract
Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal.

Abstract
BACKGROUND The purpose of this study was to evaluate the functional and oncological outcomes of patients treated for T3 laryngeal squamous cell carcinoma. Specifically comparing transoral laser microsurgery and radiotherapy/chemoradiotherapy treatment modalities. METHOD A retrospective review of patients treated for T3 laryngeal SCC between 2002 and 2010 was undertaken. RESULTS Forty-nine patients were included. 15 cases were glottic, (9 treated with TLM, 6 with RT/CRT), 33 supraglottic (6 treated with TLM, 27 with RT/CRT) and 1 subglottic subsite (treated with RT/CRT). There was no statistical difference between treatment groups for 24 month locoregional control (72.3 %), overall survival (glottis 86.7 %, supraglottic 70.4 %) and disease specific survival (glottic 93.3 % and supraglottic 74.1 %). Overall laryngeal preservation (84.9 %) was also similar in both groups. CONCLUSION Our institution is expanding the application of TLM to selected patients with T3 laryngeal carcinoma. Oncological outcomes have not been jeopardized by this approach and the treatment is well tolerated by patients with few complications.

Abstract
It remains unclear whether the efficacy of nonsurgical organ-preservation modalities (NOP) in the treatment of advanced-stage laryngeal cancer was noninferiority compared with that of total laryngectomy (TL). The objective of this study was to compare the curative effects between TL and NOP in the treatment of advanced-stage laryngeal cancer through a meta-analysis.Clinical studies were retrieved from the electronic databases of PubMed, Embase, Wanfang, and Chinese National Knowledge infrastructure. A meta-analysis was performed to investigate the differences in the curative efficacy of advanced-stage laryngeal cancer between TL and the nonsurgical method. Two reviewers screened all titles and abstracts, and independently assessed all articles. All identified studies were retrospective.Sixteen retrospective studies involving 8308 patients (4478 in the TL group and 3701 in the nonsurgical group) were included in this meta-analysis. The analysis results displayed the advantage of TL for 2-year and 5-year overall survival (OS)(OR 2.79, 95% CI 1.85-4.23 and OR 1.52, 95% CI 1.09-2.14) as well as in 5-year disease-specific survival (DSS)(OR 1.79, 95% CI 1.61-1.98), but no significant difference in 2-year DSS was detected between the 2 groups (OR = 2.09,95% CI0.69-6.40). Additionally, there were no significant differences between TL and NOP for 5-year local control (LC) either (OR = 1.75, 95% CI 0.87-3.53). When we carried out subgroup analyses, the advantage of TL was especially obvious in T4 subgroups, but not in T3 subgroups.This is the first study to compare the curative effects on advanced-stage laryngeal cancer using meta-analytic methodology. Although there was a trend in favor of TL for OS and DSS, there is no clear difference in oncologic outcome between TL and NOP. Therefore, other factors such as tumor T-stage and size, lymph node metastasis, and physical condition are also important indicators for treatment choice.

Abstract
BACKGROUND The purpose of this study was to assess the feasibility of transoral laser microsurgery (TLM) in treatment of pT3 laryngeal cancer. METHODS We conducted a retrospective case series study of 226 patients with pT3 glottic (n = 122; 54%) or supraglottic laryngeal carcinoma (n = 104; 46%). All patients were treated by TLM in combination with neck dissection (63%) and with postoperative radiotherapy (18%). Our main outcome measures were local control, organ preservation, functional outcome, overall survival, recurrence-free survival, and disease-specific survival. RESULTS Median follow-up period was 57.8 months. The 5-year organ-preservation and local control rates for all patients were 87% and 71.4%, respectively. The 5-year overall, recurrence-free, and disease-specific survival were 64.4%, 63.0%, and 83.3%, respectively. CONCLUSION Results are comparable to partial or total laryngectomy, while being superior to primary chemo(radio)therapy. TLM results in low morbidity, rapid recovery, and good function and can be a valid option for organ-preserving surgery of pT3 glottic and supraglottic cancer.

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
Historically, patients with advanced laryngeal cancer have been treated with radical surgery and adjuvant radiation therapy. Intensive surgical research has allowed surgeons to deal with almost any local extension and to propose an appropriate surgical procedure for each case. Several function-sparing surgical options are available to treat moderately advanced/advanced laryngeal cancer. Better understanding of the anatomy and biology of cancer in this anatomical site has enabled us to devise effective oncological strategies associated with a great effort to preserve laryngeal function. Numerous efforts have been made to augment the therapeutic armamentarium with the addition of chemotherapeutic agents combined with radiation therapy. For advanced laryngeal cancer, the debate is still open between partial/subtotal surgical procedures, which are more efficient but sacrifice parts of the larynx, and radiotherapy/chemoradiation protocols which can preserve the larynx and its function even though it requires radical surgery for salvage. Efforts should be made to select patients properly, in an individual basis, based on tumor characteristics, clinical aspects, patient's expectations, and the expertise of the head and neck oncologic team for the various therapeutic strategies in order to get better oncological results in association with the preservation of the laryngeal form and function, when possible.

Abstract
PURPOSE To investigate the association between the cancer cell proliferation fraction and the risk of recurrence in laryngeal cancer patients treated without systemic therapy. METHODS AND MATERIALS Paraffin-embedded tumor samples from 90 laryngeal cancer patients were stained for cyclin A and the Ki-67 antigen by immunohistochemistry. The patients were treated with partial or total laryngectomy followed by postoperative radiotherapy to a total dose of 50 Gy or greater. The median follow-up time was 91 months (minimum 48 months). RESULTS High cyclin A expression (>19% positive cancer cell nuclei, the highest tertile) was associated with a high rate of locoregional tumor recurrence and unfavorable disease-free and overall survival as compared with cases with a lower expression (p = 0.025, 0.032, and 0.042, respectively). In a multivariate analysis, high cyclin A expression was an independent predictor of poor disease-free survival (RR 2.4, 95% CI 1.2-4.9, p = 0.013) and overall survival (RR 2.1, 1.2-3.6, p = 0.012), together with a poor Karnofsky's performance status and the presence of positive margins at surgery. Ki-67 expression was not an independent predictor of survival, but cancers with high Ki-67 expression (>34% nuclei positive, the highest tertile) recurred more frequently locoregionally when treated with split-course radiotherapy than when treated with a continuous course of therapy (p = 0.035), whereas the presence of a planned split did not influence the frequency of locoregional recurrences when Ki-67 expression was lower (p = 0.93). CONCLUSION Cancer cell cyclin A expression is a novel predictive factor for outcome in laryngeal cancer treated with surgery and postoperative radiotherapy. Planned gaps in the radiotherapy course are deleterious in patients with a high proliferative fraction, and immunostaining for the Ki-67 antigen may be useful in identification of such patients.

Abstract
BACKGROUND The best therapeutic approach for the treatment of T3N0M0 (stage III) glottic carcinoma is controversial. METHOD A retrospective study of Tumor Research Project data were performed using patients with T3N0M0 glottic squamous cell carcinoma treated with curative intent by seven different treatment modalities from January 1950 to December 1996 at Washington University School of Medicine/Barnes-Jewish Hospital. RESULTS Two hundred patients with T3N0M0 glottic carcinoma were treated using seven modalities: total laryngectomy (TL, n = 30), TL with neck dissection (TL/ND, n = 40), conservation surgery alone (CS, n = 22), radiation therapy alone (RT, n = 29), TL combined with RT (TL/RT, n = 31), TL and ND combined with RT (TL/ND/RT, n = 36), and CS combined with RT (CS/RT, n = 12). The overall 5-year observed survival rate (OS) was 54% and the 5-year disease-specific survival rate (DSS) was 67%. The 5-year DSS for the individual treatment modalities included TL, 65.4%; TL/ND, 76.5%; CS, 71.4%; RT, 56.5%, TL/RT, 51.9%; TL/ND/RT, 71.4%; and CS/RT, 80%. There was no significant difference in DSS for any individual treatment modality (P =.375). The overall local and regional control rate was 74% (148 of 200). The overall recurrence rate was 37.5% with recurrence at the primary site and in the neck of 19.5% and 11%, respectively. Recurrence was not related to treatment modality. The 5-year DSS after treatment of recurrent cancer (salvage rate) was 35.8%. The incidence of distant metastasis was 11% and for second primary cancers it was 19.5%. There was no statistically significant difference in survival between necks initially treated (72%, 5-y DSS) versus necks observed and later treated if necessary (70%, 5-y DSS) (P =.797). CONCLUSIONS The seven treatment modalities had statistically similar recurrence, complication, and survival rates. Patients with clear surgical margins have a significant survival advantage compared with patients with close and involved margins. Because postoperative radiation therapy in patients with positive margins did not improve survival, formal re-resection of the site of the positive margin should be considered. In patients whose N0 neck was not treated electively, close follow-up observation with meticulous examinations combined with appropriate treatment for subsequent neck disease resulted in a similar survival rate compared with those patients whose N0 necks were treated initially. Six-year minimum follow-up is recommended for early identification of primary and neck recurrence and for discovering expected second primary cancers. Patients treated with RT and CS had statistically similar rates of survival, maintenance of voice, and acquired permanent tracheal stoma. CS is a valid alternative to RT in treating highly selected patients with T3N0 glottic carcinoma.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to evaluate the patterns of failure and the treatment of recurrences, in a series of primary irradiated patients with squamous cell carcinoma of the glottic larynx. MATERIALS AND METHODS Eight hundred and sixty-one consecutive patients were included in this study from 1963 to 1991, out of which 74 were females and 787 males. The stages were: I 56, II 26, III 15, and IV 3%. In 847 of 861 cases (98%) the primary treatment was delivered with curative intent, and out of these 834 patients received primary radical radiotherapy. RESULTS With a minimum follow up of 5 years, 274/861(32%) patients had persistent or recurrent disease; in 91% of these the persistent or recurrent disease was in the T-position, 15% in the N-position, and 5% developed distant metastases. Curative salvage attempt was possible in 207 patients, and 145 were subsequently controlled. A total of 718 (83%) patients obtained ultimate tumour control, 584 (68%) without a laryngectomy (134 of the controlled had a laryngectomy, 109 had a total laryngectomy and 25 had a partial laryngectomy). In the patients treated with curative intent, the overall 5-year local tumour control, loco-regional tumour control, disease specific survival rate and overall survival rate was 72, 70, 86 and 66%, respectively. For patients with small tumours the disease specific survival for T1a, T1b and T2 was 95, 93 and 83%, respectively. In the 718 patients cured for their glottic carcinoma, 204 new primary malignant tumours were detected. CONCLUSIONS The study shows that laryngeal glottic carcinoma can be effectively managed by primary radiotherapy and surgery salvage. The control is obtained with a high proportion of laryngeal preservation (68%). Recurrences treated with surgical salvage have a success rate of 70%. New primaries are a major problem.

Abstract
PURPOSE To review the UCSF-SUH experience in the treatment of advanced T3--4 laryngeal carcinoma and to evaluate the different factors affecting locoregional control and survival. METHODS AND MATERIALS We reviewed the records of 223 patients treated for T3--4 squamous cell carcinoma of the larynx between October 1, 1957, and December 1, 1999. There were 187 men and 36 women, with a median age of 60 years (range, 28--85 years). The primary site was glottic in 122 and supraglottic in 101 patients. We retrospectively staged the patients according to the 1997 AJCC staging system. One hundred and twenty-seven patients had T3 lesions, and 96 had T4 lesions; 132 had N0, 29 had N1, 45 had N2, and 17 had N3 disease. The overall stage was III in 93 and IV in 130 patients. Seventy-nine patients had cartilage involvement, and 144 did not. Surgery was the primary treatment modality in 161 patients, of which 134 had postoperative radiotherapy (RT), 11 had preoperative RT, 7 had surgery followed by RT and chemotherapy (CT), and 9 had surgery alone. Forty-one patients had RT alone, and 21 had CT with RT. Locoregional control (LRC) and overall survival (OS) were estimated using the Kaplan--Meier method. Log-rank statistics were employed to identify significant prognostic factors for OS and LRC. RESULTS The median follow-up was 41 months (range, 2--367 months) for all patients and 78 months (range, 6--332 months) for alive patients. The LRC rate was 69% at 5 years and 68% at 10 years. Eighty-four patients relapsed, of which 53 were locoregional failures. Significant prognostic factors for LRC on univariate analysis were primary site, N stage, overall stage, the lowest hemoglobin (Hgb) level during RT, and treatment modality. Favorable prognostic factors for LRC on multivariate analysis were lower N stage and primary surgery. The overall survival rate was 48% at 5 years and 34% at 10 years. Significant prognostic factors for OS on univariate analysis were: primary site, age, overall stage, T stage, N stage, lowest Hgb level during RT, and treatment modality. Favorable prognostic factors for OS on multivariate analysis were lower N stage and higher Hgb level during RT. CONCLUSION Lower N-stage was a favorable prognostic factor for LRC and OS. Hgb levels > or = 12.5 g/dL during RT was a favorable prognostic factor for OS. Surgery was a favorable prognostic factor for LRC but did not impact on OS. Correcting the Hbg level before and during treatment should be investigated in future clinical trials as a way of improving therapeutic outcome in patients with advanced laryngeal carcinomas.

Abstract
OBJECTIVES To analyze oncologic results, prognostic factors, and consideration of transglottic tumors as a separate entity in 73 patients with T3 glottic carcinoma treated by surgery +/- radiation therapy at La Paz University Hospital from 1984 to 1994. METHODS Sixty-four patients underwent a total laryngectomy; neck dissection was performed in 50 patients; 29 patients received postoperative radiotherapy. RESULTS The 5-year overall survival, cause-specific survival, and relapse-free survival rates were 58.1%, 66.8%, and 63.7%. Univariate analysis revealed prognostic significance for age, dyspnea, initial tracheostomy, and pathologic lymph node status. No difference was found when comparing survival and relapse rates between transglottic and glottic tumors. CONCLUSION Surgery provides acceptable rates of cancer control and survival for patients with T3 glottic carcinoma. Older patients, patients with positive neck nodes, and those presenting with dyspnea have worse prognosis. The term transglottic is merely descriptive and has little impact on prognosis.

Abstract
Treatment of laryngeal and hypopharyngeal cancers often necessitates total laryngectomy. This article reviews approaches of curing patients with these diseases while preserving their larynx. Strategies include radiation alone, neoadjuvant chemotherapy with radiation for responders, or concurrent chemotherapy and radiation. Both retrospective experiences and randomized trials evaluating differing therapies in an effort to achieve voice preservation are reported and analyzed.

Abstract
We compared the management and outcome of glottic cancer in Ontario, Canada to that in the Surveillance, Epidemiology and End Results (SEER) Program areas in the United States to determine whether the greater use of primary radiotherapy with surgery reserved for salvage in Ontario was associated with similar survival and better larynx retention rates than the U.S. approach where primary surgery is used more often. Electronic, clinical and hospital data were linked to cancer registry data and supplemented by chart review where necessary. Initial treatment and survival in patients diagnosed in the SEER areas from 1988 through 1994 were compared to patients from Ontario diagnosed from 1982 through 1995. Actuarial laryngectomy rates were compared for patients over 65 at diagnosis in the two regions. Analyses were conducted over all cases and stratified by disease stage. In localized disease (T1 or T2), conservative treatment was the most common initial treatment in both regions, although total laryngectomy was used more often in SEER than Ontario (6.2% vs. 0.2%, respectively, P <.001). In advanced disease (T3 or T4), total laryngectomy was more commonly used as initial treatment in SEER (62.9% vs. 21.0% in Ontario, P < or =.001). Over all cases, the relative survival rate was 80% in Ontario at 5 years compared to 78% in SEER (P =.33). In localized disease, the relative survival rates were 4 to 5% higher in Ontario from the second year on, while in advanced disease 2 to 3% higher rates in SEER did not approach statistical significance. Actuarial laryngectomy rates at 3 years differed between the two regions, with a 4% higher rate in SEER (P =.01). In localized disease, 12.6% of Ontario patients had a laryngectomy by 3 years postdiagnosis compared to 17.9% in SEER (P =.05). In advanced disease, the rates were 63.3% and 79.2%, respectively (P =.07). There are large differences in the management of glottic cancer between the SEER areas of the U.S. and Ontario and no evidence that a policy emphasizing radiotherapy with surgery reserved for salvage is associated with worse survival. Ultimate laryngectomy rates are lower in Ontario for localized disease and may be lower for advanced disease. Conservation treatment should be used for localized disease while the treatment decision in advanced disease may be especially sensitive to patient values for voice retention versus initial cure.

Abstract
Due to recent advances in radiation fractionation, radiochemotherapy, and conservative surgical techniques, the concept of multimodal therapy in head and neck cancer is currently changing. The recently published RTOG Phase III trial 9003, with 1,113 patients accrued, showed that hyperfractionation and accelerated fractionation with concomitant boost are more efficacious than standard fractionation for locally-advanced head and neck cancer. Acute, but not late, toxicity was also increased. Three meta-analyses have suggested that the impact of chemotherapy in head and neck cancer is small but is highly associated with the timing of therapy. Concomitant administration of radiation therapy and chemotherapy led to an absolute benefit in 5-year survival of about 10%. This finding has been further supported by recently published randomized prospective trials comparing concomitant radiochemotherapy with radiotherapy alone in advanced head and neck cancer. There is now clear evidence that radiochemotherapy provides a substantial and statistically significant improvement in survival and local-regional control, as compared to radiotherapy alone. Radiochemotherapy should be considered an accepted standard of care in cancers of the oropharynx, particularly for patients with locally-advanced disease who have a good performance status. Two randomized studies conducted by the Department of Veterans' Affairs and the EORTC, with a total of 534 patients accrued, showed that induction chemotherapy followed by radiotherapy of responders yields survival rates equal to those of total laryngectomy with postoperative radiotherapy. After 4 years, one-half to two-thirds of survivors of the chemotherapy arm retained a functional larynx. Larynx preservation using induction chemotherapy can now be regarded as feasible but still investigational. Current phase II studies show excellent larynx preservation rates using a primary concomitant radiochemotherapy with an altered fractionation regimen. More clinical and laboratory research is required to further evaluate the different treatment options of the multimodality concept, and to develop prognostic models that will allow individualization of the therapy.

Abstract
PURPOSE The use of radical radiotherapy and surgery for salvage (RRSS) in locally advanced squamous cell carcinoma (SCC) of the larynx is controversial. In the absence of randomized studies, it is unclear if RRSS can match the rates of locoregional control and survival reported for primary surgery in this setting. The aim of this study was to compare treatment outcomes of radiotherapy and surgery in comparable patients with CS III-IV SCC of the larynx. METHODS AND MATERIALS Eighty-two patients with untreated T2N+M0 or T3T4NM0 SCC of the larynx were treated with a policy RRSS at the Toronto-Sunnybrook Regional Cancer Centre between June 1980 and December 1990. The medical records at presentation were reviewed independently by a panel of three surgical oncologists blinded as to treatment outcome to determine patient suitability for laryngectomy and neck dissection using eligibility criteria adopted by recent clinical trials. Treatment outcomes for surgery-eligible patients were compared to results of comparably staged patients in the surgical literature since 1980. RESULTS Sixty-three patients (77%) were eligible for study. With a median follow-up of 3 years, radiotherapy controlled the primary in 8/20 evaluable glottic primaries and 21/41 evaluable supraglottic primaries. Forty-five percent of patients surviving 5 years retained a functional larynx. Sixteen of 29 relapsing patients were salvaged with surgery. Disease above the clavicles was controlled in 65% of T3T4N0N+ glottic primaries (compared to a published range of 53% to 79%) and 82% of T3N0 glottic primaries (compared to a published range of 69% to 84%). The 5-year overall survival of patients with T3T4 glottic cancer was 54% compared to a published range of 50% to 63%. The cause-specific survival (CSS) of patients with T3N0 glottic primaries (86% at 1 year and 73% at 2 years) was identical to the only published report of CSS in the surgical literature. CONCLUSION A policy of RRSS offers a good chance of laryngeal conservation without compromising ultimate locoregional control or survival when compared to primary laryngectomy and neck dissection in patients with locally advanced carcinoma of the larynx meeting the surgical eligibility of clinical trials.

Abstract
The management of advanced cancers of the larynx and hypopharynx has become increasingly complex as different treatment modalities, including surgery, radiation, and chemotherapy, have been combined with the goal of improving local disease control and disease-specific survival. A union of 17 comprehensive cancer centers in the United States, the National Comprehensive Care Network (NCCN), was formed in 1995 to promote state-of-the-art cancer care. To achieve this goal, multidisciplinary panels of experts from member institutions have created disease-specific practice guidelines for the evaluation and treatment of cancer patients, including those with head and neck cancers. Although detailed analysis of surgical methods and radiation techniques are beyond the scope of this article, the evolving laryngeal preservation strategies for patients with advanced, resectable hypopharyngeal or laryngeal (including supraglottic and glottic) cancers are reviewed using relevant sections of the NCCN practice guidelines as a framework for discussion.

Abstract
Controlled trials testing the concept of laryngeal preservation for patients with locally advanced stage III and IV cancers of the larynx or hypopharynx were initiated in the mid-1980s. Three randomized trials, evaluating the same cisplatin plus 5-fluorouracil induction chemotherapy regimen and conventional radiotherapy compared with surgery and radiotherapy, have been completed, and the results of two are published. In addition, a meta-analysis of these three trials was completed. The studies are critically reviewed. Conclusions from these trials are that the induction approach is feasible; local and regional control are not improved, whereas distant metastases are delayed; there is no evidence of a difference in overall survival; and of the patients alive at 3 and 5 years, a functional larynx can be preserved in 67% and 58%; there are not enough data to know if there are differences in outcome by subsite. Several unanswered questions are being addressed in phase III trials. These include defining the precise contribution of chemotherapy by comparing induction chemotherapy and radiotherapy to treatment with radiotherapy alone; determining if elective neck dissection for patients with N2N3 neck disease would improve survival; and determining whether local control can be improved by using concomitant or alternating chemotherapy and radiotherapy.
