Ichisaka T, Sano D, Kijima N, Kawakita D, Yoshimoto S, Kitayama M, Nibu KI, Oridate N. Clinical benefits of combining oral cytotoxic chemotherapeutic agents with radiotherapy in patients with T2N0 glottic squamous cell carcinoma based on the reports of the Head and Neck Cancer Registry of Japan. Oral Oncol 2024; 157:106942. [PMID: 39029387 DOI: 10.1016/j.oraloncology.2024.106942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 07/04/2024] [Accepted: 07/06/2024] [Indexed: 07/21/2024]
Abstract
BACKGROUND T2N0 glottic squamous cell carcinoma (SCC) typically responds well to radiotherapy (RT); however, achieving local control remains challenging. In cases of RT failure, total laryngectomy may be necessary. Improved local control and preservation of the larynx directly enhances patients' quality of life. Our retrospective analysis using the Japan Head and Neck Cancer Registry (JHNCR) aimed to compare the clinical benefits of RT and chemoradiotherapy (CRT) in patients with T2N0 glottic SCC. METHODS Using data from the JHNCR (2011-2015), we included 1,231 patients with T2N0 glottic SCC. Among them, 346 received curative RT and 425 underwent curative CRT. The CRT group was further divided into the oral CRT (Oral CRT, N=120) and intravenous CRT (DIV CRT, N=305) groups. This study assessed local control rate (LCR), progression-free survival (PFS), and overall survival (OS). A 1:1 propensity score-matching analysis was used to adjust for patient characteristics. RESULTS After matching, 105 pairs compared RT with Oral CRT, and 224 pairs compared RT with DIV CRT. The variables were well-balanced in the matched populations. In the matched populations, the Oral CRT group had significantly better 5-year LCR and PFS than the RT group (LCR, 89.4 % vs. 80.6 %, P=0.043; and PFS, 85.5 % vs. 72.3 %, P=0.025, respectively), while the DIV RT group had significantly better 5-year PFS than the RT group (80.1 % vs. 68.6 %, P=0.026). CONCLUSIONS The clinical benefits of better local and disease controls were observed when oral chemotherapy was added to RT in patients with T2N0 glottic SCC. Thus, the significance of adding oral chemotherapeutic agents to RT in the treatment of T2N0 glottic SCC requires further prospective investigation.

Abstract
BACKGROUND The aim of this study is to examine the outcomes of an accelerated fractionated irradiation for N0 glottic carcinoma. METHODS In this retrospective analysis, 29 patients with N0 glottic carcinoma treated by radiation therapy were enrolled. Thirteen patients had T1a disease, six had T1b disease, and ten had T2 disease. A fractional dose of 2.1 Gy was administered to seven patients. The total doses were 65.1 and 67.2 Gy in four and three patients, respectively. A fractional dose of 2.25 Gy was administered to 22 patients. The total doses were 63 and 67.5 Gy in 21 patients and 1 patient with T2 disease, respectively. Additionally, 13 patients underwent the use of TS-1 (80-100 mg per day). RESULTS The median follow-up period was 33 months, and the 3-year local control rate was 95.6%. No patient had a lymph node or distant recurrence. As acute adverse events, grades 2 and 3 dermatitis were observed in 18 patients and 1 patient, and grades 2 and 3 mucositis were observed in 15 patients and 1 patient. As a late adverse event, one patient required tracheotomy because of laryngeal edema occurring. CONCLUSIONS Accelerated fractionated irradiation may be an option in the radiation therapy of N0 glottic carcinoma because of its ability to shorten the treatment time.

Abstract
BACKGROUND We report outcomes among patients with T2 and select T3 glottic squamous cell carcinoma (SCC) treated with radiotherapy. METHODS We reviewed T2 and T3 (only paraglottic space invasion) N0 M0 glottic SCC patients treated with curative-intent hypofractionated larynx radiotherapy, with or without concurrent systemic therapy. RESULTS Of 71 patients, those who received concurrent chemotherapy (23/71; 32%) had worse prognostic factors, including impaired cord mobility (70% vs. 40%, p = 0.02) and larger median gross tumor volume (3.0 vs. 1.6 cm3 , p = 0.003). Over a median follow-up of 3.8 years, 2-year local control among patients with impaired cord mobility appeared higher for those who received chemotherapy (88% vs. 61%, p = 0.12), but the difference was not statistically significant. Acute and late toxicity rates were not higher among patients who received chemotherapy. CONCLUSIONS The addition of concurrent platinum-based chemotherapy to hypofractionated larynx radiotherapy among patients with early-stage glottic SCC with impaired cord mobility appears safe and worthy of additional investigation.

Cancers (Basel) 2021; 13:cancers13122971. [PMID: 34199326 PMCID: PMC8231857 DOI: 10.3390/cancers13122971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 06/06/2021] [Accepted: 06/09/2021] [Indexed: 11/16/2022] Open
Abstract
This meta-analysis was conducted to assess the efficacy and adverse events associated with S-1 chemotherapy combined with radiotherapy for patients with head and neck cancer. The PubMed, Embase, and Cochrane Library databases were searched up to 10 February 2021. Eligible studies included clinical trials using S-1 chemotherapy combined with radiotherapy for head and neck cancer patients that measured tumor response, local control rate, overall survival, and grade 3/4 adverse events. A meta-analysis was performed using a random effects model. Twelve trials involving 378 patients met the selection criteria. The objective response and clinical benefit rate (complete/partial response and stable disease) of S-1 chemotherapy with radiotherapy were 86.3% (95% confidence interval (CI), 60.3-96.3) and 88.3% (95% CI, 70.1-96.1), respectively. The median 3-year local control rate, 3-year overall survival rate, and grade 3/4 adverse event rate were 84.0% (95% CI, 71.4-91.7), 69.6% (95% CI, 54.9-81.1), and 42.0% (95% CI, 36.2-48.0), respectively. S-1 combined with radiotherapy for patients with head and neck squamous cell carcinoma results in a good tumor response, favorable survival rate, and low toxicity. A prospective randomized, double-blind trial is required to assess the efficacy and safety of S-1 combined with radiotherapy to treat HNSCC.

Abstract
Subglottic small cell carcinoma (SSMCC) is a rare type of neoplasm, meaning that laryngeal cancer guidelines in several countries, including the National Comprehensive Cancer Network (NCCN) guidelines, do not include treatment principles for SSMCC. Angiogenesis is an established factor in tumor initiation, growth, and dissemination. Apatinib mesylate, an orally administered drug, is a novel inhibitor of vascular endothelial growth factor receptor-2, a key mediator of angiogenesis, and has been shown to be safe and efficacious in the treatment of certain types of malignant tumors. To the best of our knowledge, there are few reports on the treatment of SSMCC with apatinib combined with concurrent chemoradiotherapy. In the present report of SSMCC in a 64-year-old woman, oral apatinib was given daily at a dose of 250 mg in combination with concurrent chemoradiotherapy; the only toxicities reported were mild leukopenia and finger numbness. Clear and rapid efficacy was observed with the disappearance of the tumor mass. Our findings indicate that apatinib combined with concurrent chemoradiotherapy may be effective in patients with SSMCC, with adverse reactions within the manageable range, thus representing an additional treatment option for this type of malignancy.

Abstract
BACKGROUND Prognostic risk factors of patients with initially diagnosed T2N0M0 glottic cancer remain unclear. This study was aimed to conduct a comprehensive analysis to identify valuable prognostic risk factors for initially diagnosed T2N0M0 glottic cancer. METHODS Data of patients with initially diagnosed T2N0M0 glottic cancer were extracted from the Surveillance, Epidemiology, and End Results database. Survival analyses and Cox regression analyses were conducted to evaluate overall survival (OS) and cancer-specific survival (CSS). In consideration of competing events, the competing risk (CR) analysis was applied. Furthermore, propensity-score matching (PSM) was applied to mimic randomized-controlled trials and reduce selection bias. RESULTS A total of 923 eligible patients met the inclusion criteria. Survival analyses showed that age, marital status, primary site surgery, and radiation were independent predictors of OS. Besides, age, marital status, primary site surgery, radiation, and chemotherapy were independent predictors of CSS. Cox regression analyses and the CR analysis were basically consistent with this result. In addition, an internal validation and PSM were performed to explore the role of chemotherapy. CONCLUSION We conducted a comprehensive analysis to prove that age, marital status, primary site surgery, radiation, and chemotherapy may be valuable prognostic risk factors for initially diagnosed T2N0M0 glottic cancer. Primary site surgery and radiation should be recommended, whereas chemotherapy was likely not suitable so far. Furthermore, we constructed a CR nomogram to predict survival rates.

How Should We Approach Locally Advanced Squamous Cell Carcinoma of Head and Neck Cancer Patients Ineligible for Standard Non-surgical Treatment? Curr Oncol Rep 2020; 22:118.

Abstract
PURPOSE OF REVIEW Cisplatin has been established as one of the most important agents in multidisciplinary treatment for head and neck cancer (HNC). However, since HNC patients are often elderly and typically have several comorbidities, a limited number of patients can tolerate high-dose cisplatin in real-world HNC populations. We will provide a review of therapeutic alternatives to high-dose cisplatin-based treatment in the setting of definitive and postoperative chemoradiotherapy (CRT) or induction chemotherapy. RECENT FINDINGS Clinical criteria for CDDP ineligibility have been discussed in HNC. When considering cisplatin-based chemotherapy as part of a non-surgical approach, precise evaluation of the patient's physical condition, nutritional status, and comorbidities is needed. Upfront surgery is an important option with high curability, if a de-intensified non-surgical approach is estimated to be unavoidable. Although no prospective data are available regarding alternatives to definitive cisplatin-based combination therapy for patients undergoing a non-surgical approach, cetuximab, carboplatin, or split-dose cisplatin-based regimens may be employed for cisplatin-ineligible patients in clinical practice. The combination of immune checkpoint inhibitors with radiotherapy may be a promising novel approach, and some trials are currently targeting the specific cohort of patients ineligible for high-dose cisplatin. There are no standard treatments for patients ineligible for high-dose cisplatin. A personalized treatment strategy should be proposed based on the individual benefit-to-risk ratio of each treatment option in patients ineligible for the standard of care. Prospective clinical trials for cisplatin-ineligible patients with locally advanced HNC still need to be performed.

Abstract
BACKGROUND The purpose of this study was to evaluate the patterns of care and survival in the nonsurgical management of early-stage (T1/2 N0 M0) laryngeal cancer. STUDY DESIGN This was a retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) database during the period 2004 to 2015. Patients diagnosed with T1/2 N0 M0 laryngeal SCC definitively treated without surgery were included. Study predictors were age, gender, race, marital status, histologic grade, stage, and management strategy defined as radiotherapy (RT), chemotherapy, chemoradiotherapy (CRT), or no treatment. Study outcomes were overall survival (OS) and disease-specific survival (DSS). RESULTS In total, 3221 patients comprised the final sample. Over half of the lesions were stage I (63.8%); 74.0%, 24.8%, and 1.2% were located in the glottis, supraglottis, and subglottis, respectively. RT (77.6%) was the preferred nonsurgical treatment modality, followed by CRT (12.7%). A greater proportion of patients with stage II disease (25.1%) received CRT compared with those with stage I (5.6%). Similarly, patients receiving CRT were significantly younger and more likely to present with higher-grade lesions located in the supraglottis and subglottis. In the multivariate model, the risks of both disease-specific and overall death were increased by age, male gender, supraglottic and subglottic location, stage II disease, CRT, and no treatment. CONCLUSIONS Definitive RT was the preferred treatment modality regardless of tumor characteristics. CRT was more often selectively reserved for younger patients with higher grade, stage II tumors located in the supraglottis and subglottis. This approach may be driven by the poorer rates of survival associated with these particular characteristics. CRT did not appear to improve survival in comparison with RT after controlling for subsite and disease severity; however, future clinical studies are required to validate this finding.

Abstract
OBJECTIVES This multicenter retrospective cohort study aimed to evaluate the significance of adding S-1 to radiotherapy (RT) for the treatment of T2N0 glottic cancer using a propensity score matched analysis in Japan. MATERIALS AND METHODS This study was conducted on 287 patients with T2N0 glottic cancer who were treated with definitive RT or chemoradiotherapy with S-1 (S-1 RT) between April 2007 and March 2017. Propensity score matched analysis was performed to ensure the well-balanced characteristics of the groups of patients who received RT alone and S-1 RT. Overall, progression-free and laryngectomy-free survivals and local control and laryngeal preservation rates were compared. RESULTS Fifty-four pairs of patients were selected after performing propensity score matched analysis. Clinical characteristics were well-balanced between the two groups. The overall survival of patients in the S-1 RT group was significantly better than those in the RT alone group (P = 0.008). The progression-free and laryngectomy-free survivals of patients in the S-1 RT group were also better than those in the RT alone group; however, the differences were not significant. In contrast, patients in the S-1 RT group had slightly lower local control and laryngeal preservation rates compared with those in the RT alone group. The incidence of dermatitis in the S-1 RT group was significantly higher than that in the RT alone group in the matched population (P = 0.013). CONCLUSIONS The addition of S-1 to RT for the treatment of T2N0 glottic cancer was not associated with better local control and laryngeal preservation rates in this study.

Abstract
Primary subglottic carcinoma is rare and surgery is the most common therapeutic strategy for Chinese patients with this disease. To retrospectively evaluate surgically treated primary subglottic carcinoma treated with surgery. Patients with primary subglottic carcinoma who initially underwent surgery from 2005-2010 were grouped by surgical procedures with or without laryngeal function preservation and reviewed. Of 1815 patients with laryngeal cancer, 23 had a subglottic origin. Of these, 21 initially underwent surgery; 12 had 'early' (stage I/II) disease, and nine had 'advanced' (stage III/IV) disease. The actuarial 5-year OS was 73.9% [95% confidence interval (54.1% ∼ 93.7%)] for patients with squamous cell carcinoma. Among patients with early disease, the 5-year OS and DFS were 80% for partial laryngectomy and 71.4% for total laryngectomy. Patients with advanced disease underwent total laryngectomy, and the 5-year OS and DFS were 62.5%. Satisfactory oncologic outcomes can be achieved with initial surgery. Patients with early disease who underwent partial laryngectomy had a comparable prognosis to those who underwent total laryngectomy; deglutition and speech function were maintained.

Abstract
Background: The recommended treatment strategies for early glottic carcinoma with intent of larynx preservation are primarily radiotherapy. However, the outcomes of radiotherapy for bulky T1 or T2 glottic carcinoma are unsatisfactory. We designed a protocol consisting of concurrent chemoradiotherapy using S-1 as the radiosensitizer. We have performed this protocol in patients with favorable T2 lesions and demonstrated its efficacy and safety. In contrast, we have treated non-bulky T1 glottic carcinomas with 2.25 Gy per fraction, for a total of 25-28 fractions, starting in 2011 to improve efficacy and shorten the treatment period. Since this treatment strategy was implemented for T1 disease, no local failure has occurred to date, and it appears to be almost as safe as radiotherapy using 2.0 Gy per fraction. With the aim of improving the local control rate and shortening the treatment period primarily for favorable T2 disease, we changed the dose of radiation in our protocol from 2.0 Gy to 2.25 Gy per fraction, for a total of 25 fractions (from 30 fractions). The present study aims to evaluate the efficacy and safety of this new protocol. Methods: This study will be conducted as a clinical, prospective, single-armed, non-randomized trial. Patients are to receive S-1 (55.3 mg /m2 /day, once daily) and radiotherapy (2.25 Gy per fraction, for a total of 25 fractions). S-1 and radiotherapy are started on the same day that radiotherapy is performed, 3-6 hours after oral administration of S-1. The primary study aim is the 3-year local control rate. The secondary study aims are overall survival, voice-preservation survival, disease-free survival, complete response rate, completion rate, and toxicity. Result and conclusion: This is the first single-center, non-randomized, prospective study of concurrent chemoradiotherapy with S-1 and hypofractionated radiotherapy to be conducted. The trial will evaluate the efficacy and safety of our protocol.

Abstract
Background To assess the efficacy of concurrent chemoradiotherapy (CCRT) with daily low-dose cisplatin (CDDP) plus weekly docetaxel (DTX) for patients with T2N0 glottic cancer. Methods Between January 2004 and December 2013, 62 treatment-naive patients with histologically proven T2N0 glottic cancer were treated with concurrent chemoradiotherapy. Radiation therapy (RT; 2 Gy daily fractions up to a total dose of 66 Gy) was administered in combination with daily low-dose CDDP (6 mg/m2, five times a week), plus weekly DTX (10 mg/m2) for up to 4 weeks from the commencement of RT. Results Median duration of follow-up was 70 months. The actuarial 3-year and 5-year overall survival rates were 95% and 93%. The 3-year and 5-year cause-specific survival rates were both 100%. The actuarial 3-year and 5-year local control rates were 94% and 94%, respectively. Hematologic toxicity (neutoropenia of severity ≥ Grade 3) was observed in 8% of the patients, and non-hematologic toxicity (radiation mucositis of severity ≥ Grade 3) developed in one patient (2%). Radiation dermatitis of severity ≥ Grade 3 and laryngeal necrosis developed in one patient. Conclusion CCRT with weekly DTX and low-dose CDDP appears to be a practical and safe modality and is expected to improve local control. Trial registration UMIN000025046. Registered 1 October 2015, retrospectively registered.

Abstract
OBJECTIVE The goals of treatment for head and neck cancer are cure and organ-function preservation. For organ preservation, primary treatment via radiotherapy alone is thought to be insufficient for Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx. The objective of the present study was to investigate the efficacy and safety of concurrent chemoradiotherapy with S-1 for patients with Stage II squamous cell carcinoma of the pharynx or larynx for primary organ preservation. METHODS Previously untreated patients with Stage II squamous cell carcinoma of the larynx, oropharynx or hypopharynx received three courses of S-1 (40 or 50 mg twice a day; 2 weeks of administration followed by 1 week of rest every 3 weeks) during conventional radiotherapy (a single daily fraction of 1.8 Gy) to a total dose of 70.2 Gy. The primary endpoint was the local control rate at 3 years. RESULTS From August 2009 to October 2012, 37 patients were evaluated for the study. The overall response rate was 100%. The 3-year local control rate was 89.0% (95% confidence interval, 78.9-99.2%), and the 3-year overall survival rate was 97.2% (95% confidence interval, 91.8-100%). Mucositis and dermatitis in the radiation field were the most common acute adverse events observed. The rates of Grade 3 mucositis and dermatitis were 27 and 35%, respectively. No patients experienced Grade 4 acute adverse events. The treatment completion rate was 89.2%. CONCLUSION Concurrent chemoradiotherapy with S-1 was safe and effective in improving local control for Stage II squamous cell carcinoma of the pharynx or larynx.

Abstract
OBJECTIVE We examined the completion rate, safety, and adverse events in patients with T2N0 glottic carcinoma who received chemoradiotherapy with S-1 (tegafur-gimeracil-oteracil potassium). METHODS In T2N0 glottic carcinoma patients, we retrospectively compared the local control rate and outpatient therapy completion rate between 20 patients who received radiotherapy plus S-1 (S-1 group) and 20 who received radiotherapy alone (RT group). RESULTS Local recurrence was not detected in any of the 20 subjects from the S-1 group, whereas local recurrence was found in 4 of the 20 subjects (20%) from the RT group (p<0.05). Outpatient treatment was completed by 15 of the 20 subjects from the S-1 group and 17 of the 20 subjects from the RT group (p=0.43). CONCLUSION We investigated chemoradiotherapy with S-1 in patients who had T2N0 glottic carcinoma and found a higher local control rate when compared with radiotherapy alone as well as comparable safety for outpatient delivery.

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

Abstract
This study investigated the maximum tolerated dose (MTD) of S-1 with concurrent radiotherapy in patients with head and neck cancer, based on the frequency of dose-limiting toxicities (DLT). S-1 was administered orally at escalating doses from 40 mg/m(2) b.i.d. on the days of delivering radiotherapy, which was given at a total dose of 64-70 Gy in 32-35 fractions over 6-7 weeks. A total of 12 patients (3 patients at 40 mg/m(2), 6 patients at 60 mg/m(2), and 3 patients at 80 mg/m(2)) were enrolled in this trial. At the dose of 80 mg/m(2), two of the three patients developed DLT (Grade 3 anorexia and rhabdomyolysis) due to S-1, so the MTD was determined to be 80 mg/m(2). Among the 12 enrolled patients, 9 (75%) showed a complete response and 3 (25%) showed a partial response. The overall response rate was 100%. The recommended dose of S-1 with concurrent radiotherapy is 60 mg/m(2).

Abstract
AIM S-1 is an oral anticancer fluoropyrimidine formulation consisting of tegafur, 5-chloro-2,4-dihydroxypyridine and potassium oxonate. The aim of this study was to evaluate the pharmacokinetics and bioequivalence of a newly developed generic formulation of S-1 in Chinese cancer patients in comparison with the branded reference formulation of S-1. METHODS A single-dose, randomized-sequence, open-label, two-way self-crossover study was conducted in 30 Chinese cancer patients. The subjects alternatively received the two formulations (40 mg/m(2), po) with a 7-d interval. Plasma concentrations of FT, CDHP, Oxo, and 5-Fu were determined using LC-MS/MS. Pharmacokinetic parameters, including Cmax, Tmax, t1/2, AUC0-t, and AUC0-∞ were determined using non-compartmental models with DAS2.0 software. Bioequivalence of the two formulations were to be evaluated according to 90% CIs for the log-transformed ratios of AUC and Cmax of S-1. Adverse events were evaluated through monitoring the symptom, physical and laboratory examinations, ECGs and subject interviews. RESULTS The mean values of Cmax, AUC0-t, and AUC0-∞ of FT, 5-Fu, CDHP, and Oxo for the two formulations had no significant differences. The 90% CIs for natural log-transformed ratios of Cmax, AUC0-t, and AUC0-∞ were within the predetermined bioequivalence acceptance limits. A total of 11 mild adverse events, including fatigue, nausea and vomiting, anorexia, diarrhea and myelosuppression, were observed, and no serious and special adverse events were found. CONCLUSION The newly developed generic formulation and reference formulation of S-1 have similar pharmacokinetics with one dose (40 mg/m(2)) in Chinese cancer patients. Both the formulations of S-1 are well tolerated.

Abstract
BACKGROUND AND PURPOSE Primary subglottic cancer is a rare malignancy. We investigated the efficacy and toxicity of radiotherapy for subglottic cancer. PATIENTS AND METHODS Nineteen patients with primary squamous cell carcinoma of the subglottis received radiotherapy, 14 of whom also underwent chemotherapy. Of the 19 patients, 15 received definitive radiotherapy to the gross tumors with total doses of 70-70.2 Gy in 35-39 fractions, and 4 underwent preoperative radiotherapy with total doses of 37.8-55.8 Gy in 21-31 fractions, followed by total laryngectomy. RESULTS Of the 19 patients, 5 developed local progression and 2 developed distant metastasis at the median follow-up period of 5 years. The 5-year local control and disease-free rates were 74 and 63%, respectively. Three patients died of tumor progression, and the 5-year overall and disease-free survival rates were 80 and 63%, respectively. Regarding acute toxicities, transient mucositis and dermatitis of grade 3 or lower were observed in all patients, but there were no late toxicities of grade 3 or higher. CONCLUSION Radiotherapy is a safe and effective treatment for patients with primary squamous cell carcinoma of the subglottis. The use of chemotherapy together with radiotherapy may enhance treatment efficacy and contribute to larynx preservation through good local control.

Abstract
BACKGROUND The purpose of this phase I trial of S-1 chemotherapy in combination with pelvic radiotherapy for locally recurrent rectal cancer was to determine the maximum tolerated dose (MTD), recommended dose (RD), and dose-limiting toxicity (DLT) of S-1. METHODS We enrolled 9 patients between April 2005 and March 2009. Radiotherapy (total dose, 60 Gy in 30 fractions) was given to the gross local recurrent tumor and pelvic nodal metastases using three-dimensional radiotherapy planning. We administered oral S-1 twice a day on days 1-14 and 22-35 during radiotherapy. The dose of S-1 was initially 60 mg/m(2)/day and was increased to determine the MTD and RD for this regimen. RESULTS DLT appeared at dose level 2 (70 mg/m(2)/day) in 2 patients, who experienced grade 3 enterocolitis and consequently required suspension of S-1 administration for longer than 2 weeks. Hematological toxicity was mild and reversible. At the initial evaluation, complete regression and partial regression were seen in 1 patient (11%) and 2 patients (22%), respectively. CONCLUSION This phase I trial of S-1 chemotherapy with pelvic radiotherapy for locally recurrent rectal cancer revealed that the MTD for S-1 was 70 mg/m(2)/day and the RD was 60 mg/m(2)/day.

Abstract
OBJECTIVE Management of laryngeal cancer has focused on improving survival while preserving function. Over the past 20 years, the trends have shifted from surgery to chemoradiotherapy and presently we are facing various challenges. It is imperative to re-examine what has happened and what can be done. METHODS Review of the literature along with our experience in the management of functional organ preservation for laryngeal cancer. RESULTS There was an increasing use of chemoradiotherapy with a decreasing use of surgery. Inappropriate patient selection along with inability to properly apply salvage surgeries have been presumed to be responsible for survival deterioration in laryngeal cancer. Reports concerning late adverse events after chemoradiotherapy are also increasing. Reconfirmation of the multidisciplinary team approach is imperative. Transoral laser microsurgery can be used for early laryngeal cancer and, in some experienced institutes, for advanced-stage cancers. Supracricoid laryngectomy demonstrated satisfactory oncologic and functional outcomes, based on our experience. CONCLUSIONS Treatment selection for larynx preservation should not merely be decided by guidelines but considering each patient's individual condition. Head and neck surgeons are encouraged to take reasonable risks in performing salvage larynx preservation surgery when it is the only option to save a functioning larynx.
