Abstract
BACKGROUND/PURPOSE Post radiation mucosal ulcers (PRMU) after treatment for oropharyngeal squamous cell carcinoma (OPSCC) can have a huge negative impact on patients' quality of life, but little is known concerning risk factors and the impact of fraction size. Therefore, the goal of this study was to determine the pattern of PRMU development and to identify risk factors after a hypofractionated stereotactic body radiotherapy boost (SBRT) compared to conventionally fractionated radiotherapy for OPSCC. MATERIAL AND METHODS We performed a retrospective cohort study (N = 332) of OPSCC patients with ≥ 1-year disease-free survival, treated with 46 Gy Intensity Modulated Radiotherapy (IMRT) (2 Gy fractions) followed by either an SBRT boost of 16.5 Gy (5.5 Gy fractions) (N = 180), or 24 Gy IMRT (2 Gy fractions) (N = 152). PRMU (grade ≥ 2) was scored when observed > three months after the last radiotherapy (RT) fraction (CTCAE v5.0). Potential risk factors were analyzed with Cox regression models using death as competing risk. Dose at the PRMU site was calculated by projecting delineated PRMU on the planning CT. RESULTS All cases of PRMU (N = 64) occurred within 24 months; all were grade 2. The cumulative incidence at 2 years in the SBRT boost group was 26% (N = 46) vs. 12% (N = 18) for conventional fractionation (p = 0.003). Most PRMU developed within nine months (N = 48). PRMU occurring > nine months (N = 16) were mainly observed in the SBRT boost group (N = 15). Sex (p = 0.048), acute tube feeding (p = < 0.001), tumor subsite tonsil (p = 0.001), and N stage (p = 0.017) were associated with PRMU risk at multivariable regression in the hypofractionated SBRT boost group. All 25 delineated PRMU were located within the high dose regions. CONCLUSION The risk of PRMU should be included in the cost benefit analysis when considering future research using a hypofractionated SBRT boost for OPSCC patients.

Abstract
Purpose . The transoral robotic surgery is a newer modality being used in surgical treatment of early oropharyngeal cancer. The aim of this study is to assess the outcome of these cases in terms of two year disease free survival and overall survival. Methods Between July 2016 and September 2018, 58 patients suffering from early oropharyngeal cancer underwent transoral robotic surgery with neck dissection at a tertiary referral centre. 43 of them have completed two years follow up and were analyzed for disease free survival and overall survival. 41 patients had HPV analysis done . Results The surgical margins were positive in 9/43 patients ( 6 in upfront surgery and 3 in the salvage cohort). Adjuvant therapy was administered to 16/34 patients on account of either positive margins or multiple nodal metastasis. 88% patients were found to be HPV negative. The two year disease free survival for the upfront cohort was 88.2% and salvage cohort was 55.5%. The overall survival was 86.05%. Conclusions The study highlights good locoregional control and two year disease free survival in HPV negative oropharyngeal cancer undergoing robotic surgery. Additionally, a positive surgical margin and recurrence were the statistically significant variables influencing 2 year disease free survival. Trans oral robotic surgery is an excellent tool for early tumors of the oropharynx. The presence of a positive surgical margin is a grim sign for survival and has a significant impact on positive outcome.

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.

Early Clinical Outcomes of Intensity Modulated Radiation Therapy/Intensity Modulated Proton Therapy Combination in Comparison with Intensity Modulated Radiation Therapy Alone in Oropharynx Cancer Patients. Cancers (Basel) 2021; 13:cancers13071549. [PMID: 33801766 PMCID: PMC8037748 DOI: 10.3390/cancers13071549] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 03/18/2021] [Accepted: 03/24/2021] [Indexed: 11/16/2022] Open
Abstract
Simple Summary Intensity-modulated proton therapy (IMPT) is expected to reduce toxicity more effectively than intensity-modulated radiation therapy (IMRT) in treating oropharynx cancer (OPC) patients. Because of long waiting before starting IMPT, authors began IMRT first and then determined whether to continue IMRT or to switch into IMPT at time of adaptive re-plan, based on the rival plan comparison in 148 OPC patients. Early clinical outcomes were analyzed and compared between IMRT alone and IMRT/IMPT combination groups through propensity score matching method. We found that, with comparable oncologic outcomes, more favorable acute toxicity profiles (mucositis and need for analgesic use) were achieved following IMRT/IMPT combination than IMRT alone. Abstract Purpose: To report the early clinical outcomes of combining intensity-modulated radiation therapy (IMRT) and intensity-modulated proton therapy (IMPT) in comparison with IMRT alone in treating oropharynx cancer (OPC) patients. Materials and Methods: The medical records of 148 OPC patients who underwent definitive radiotherapy (RT) with concurrent systemic therapy, from January 2016 till December 2019 at Samsung Medical Center, were retrospectively reviewed. During the 5.5 weeks’ RT course, the initial 16 (or 18) fractions were delivered by IMRT in all patients, and the subsequent 12 (or 10) fractions were either by IMRT in 81 patients (IMRT only) or by IMPT in 67 (IMRT/IMPT combination), respectively, based on comparison of adaptive re-plan profiles and availability of equipment. Propensity-score matching (PSM) was done on 76 patients (38 from each group) for comparative analyses. Results: With the median follow-up of 24.7 months, there was no significant difference in overall survival and progression free survival between groups, both before and after PSM. Before PSM, the IMRT/IMPT combination group experienced grade ≥ 3 acute toxicities less frequently: mucositis in 37.0% and 13.4% (p < 0.001); and analgesic quantification algorithm (AQA) in 37.0% and 19.4% (p = 0.019), respectively. The same trends were observed after PSM: mucositis in 39.5% and 15.8% (p = 0.021); and AQA in 47.4% and 21.1% (p = 0.016), respectively. In multivariate logistic regression, grade ≥ 3 mucositis was significantly less frequent in the IMRT/IMPT combination group, both before and after PSM (p = 0.027 and 0.024, respectively). AQA score ≥ 3 was also less frequent in the IMRT/IMPT combination group, both before and after PSM (p = 0.085 and 0.018, respectively). Conclusions: In treating the OPC patients, with comparable early oncologic outcomes, more favorable acute toxicity profiles were achieved following IMRT/IMPT combination than IMRT alone.

Abstract
The length and quality of head and neck cancer survivorship continues to meaningfully improve. Radiotherapy has been central to this process through advances in treatment delivery, fractionation schemas, radiosensitizing systemic therapy, and thoughtful interplay with technical surgical improvements. The future looks brighter still, with ongoing progress in targeted biologic therapy, immuno-oncology, and molecular-genetic tumor characterization for personalized treatment. Head and neck cancer, a disease once fraught with nihilism and failure, is evolving into a major success story of modern multidisciplinary cancer care.

Abstract
Background Transoral surgery (TOS) has been widely applied for early T‐stage head and neck cancer (HNC). The resection is performed with a minimum safety margin for function preservation under a limited surgical field; therefore, it is difficult to have a strong conviction about the complete resection. This study aims to evaluate the completeness of the initial TOS procedure; possibility of primary control by TOS alone; and predictive factors in patients with early T‐stage laryngeal, oropharyngeal, and hypopharyngeal cancer. Methods Patients were treated by TOS at the primary site with or without neck dissection. The patients were divided into two groups based on the pathological evaluation of their surgical specimens: the control (observation) group, in that the resection was considered complete and the intervention (second‐look procedure) group, in that incomplete tumor resection was suspected. The predictive factors for the possibility and/or limitations of complete resection by TOS were then analyzed. Results The study enrolled 26 and 25 patients in the control and intervention group, respectively. The success rate for single resection was 66% and the predictive factor was tumor depth obtained by enhanced computed tomography (CT) examination (odds ratio, 7.870, P = .0243). The success rate for definitive therapy by TOS alone was 83% and the predictive factor was poor differentiation observed on pathological examination (odds ratio, 6.800, P = .0248). Conclusions TOS has the potential for both definitive resection and function preservation with minimal invasiveness. Identification of the risk factors for TOS is advantageous for accurate treatment selection in patients with early T‐stage HNC.

Abstract
Background/purpose: To determine the efficacy and toxicity profile of a stereotactic body radiotherapy (SBRT) boost as a first line treatment in patients with oropharyngeal squamous cell carcinoma (OPSCC). Materials and methods: We performed a retrospective cohort study in 195 consecutive OPSCC patients with T1-small T3 disease, treated at Erasmus MC between 2009 and 2016 with a SBRT (3 × 5.5 Gy) boost after 46 Gy IMRT. Primary endpoints were disease-specific survival (DSS) and Grade ≥3 toxicity (Common Terminology Criteria). The Kaplan-Meier method and Cox regression model were applied to determine rates and risk factors. Results: The median follow-up was 4.3 years. Treatment compliance was high (100%). Rates of 5-year DSS and late grade ≥3 toxicity were 85% and 28%, respectively. Five-year overall survival was 67%. The most frequently observed toxicities were mucosal ulceration or soft tissue necrosis (n = 30, 5 year 18%), dysphagia or weight loss (n = 18, 5 year 12%) and osteoradionecrosis (n = 11, 5 year 9%). Current smoker status (hazard ratio [HR] = 2.9, p = .001) and Charlson Comorbidity Index ≥2 (HR = 1.9, p = .03) were was associated with increased toxicity risk. Tooth extraction prior to RT was associated with increased osteoradionecrosis risk (HR = 6.4, p = .006). Conclusion: We reported on outcomes in the largest patient series to date treated with a hypofractionated boost for OPSCC. Efficacy was good with survival rates comparable to conventionally fractionated (chemo)radiotherapy. Grade ≥3 toxicity profiles showed high rates of soft tissue necrosis and osteoradionecrosis. Strategies to mitigate severe toxicity risks are under investigation to improve the tolerability of the SBRT boost.

Abstract
Head and neck cancers comprise 4% of the cancer burden in the United States each year. Many types of head and neck cancers present as an asymptomatic, nontender neck mass or nonspecific symptoms, such as hoarseness, sore throat, and pain. Head and neck cancers are frequently diagnosed incidentally by the primary care physician or dentist. This review summarizes the epidemiology, clinical manifestations, diagnosis, and treatment of several common head and neck cancers in order to provide an increased awareness for the internist to facilitate early detection of these diseases.

Abstract
Because of the common shared risk factors of smoking and heavy alcohol consumption, literature involving oropharyngeal squamous cell carcinoma (OPSCC) is often combined with oral squamous cell carcinoma. Human papilloma virus is now confirmed to be a major risk factor of OPSCC with its distinct epidemiology and favorable treatment outcome. The impact of adjuvant chemoradiation in the setting of positive surgical margins remains unclear but is likely influenced by tumor biology. This article reviews the tumor biology of OPSCC and summarizes recent findings on outcomes following surgical treatment of OPSCC.

The resection is performed with a minimum safety margin for function preservation under a limited surgical field of view, making it difficult to be certain of complete resection. OBJECTIVE Our aim is the evaluation of the completeness of resection by initial TOVS resection, and the possibility of primary control by TOVS alone, allowing for repeat procedures for function preserving treatment in early T stage laryngeal, oropharyngeal, and hypopharyngeal cancer patients. METHODS Patients are treated by TOVS for the primary site with or without neck dissection. Patients are divided in two groups based on the results of the pathological evaluation of the surgical specimen; the control group in which the resection is considered to be complete, and the intervention (second-look procedure) group in which incomplete tumor resection is suspected. The predictive factors for the possibility of complete resection by TOVS will then be analyzed. RESULTS Patient enrollment started on January 1, 2014, and closed on March 31, 2016, with 54 patients. The control group consists of 27 patients, the intervention group is 21 patients, and 6 patients were excluded. There were no clinical differences between the control and intervention groups. The observation period will end on December 31, 2018. CONCLUSIONS TOVS has potential for both definitive resection and function preservation with minimal invasiveness. Identifying the limitations of TOVS is beneficial to ensure accurate treatment selection in early T stage head and neck cancer patients.

Prognostic impact of leukocyte counts before and during radiotherapy for oropharyngeal cancer. Clin Transl Radiat Oncol 2017; 7:28-35. [PMID: 29594226 PMCID: PMC5862666 DOI: 10.1016/j.ctro.2017.09.008] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2017] [Revised: 09/25/2017] [Accepted: 09/26/2017] [Indexed: 12/12/2022] Open
Abstract
Introduction Peripheral blood count components are accessible and evidently predictive in other cancers but have not been explored in oropharyngeal carcinoma. We examine if there is an association between the use of intensity-modulated radiotherapy (IMRT) or intensity-modulated proton therapy (IMPT) and lymphopenia, as well as if there is an association between baseline neutrophilia, baseline leukocytosis and lymphocyte nadir in oropharyngeal cancer. Materials and Methods Analysis started with 150 patients from a previous case to case study design, which retrospectively identified adults with oropharyngeal carcinoma, 100 treated with IMRT in 2010-2012 and 50 treated with IMPT in 2011-2014. Pretreatment leukocyte, neutrophil, lymphocyte, and hemoglobin levels were extracted, as were neutrophil and lymphocyte nadir levels during radiotherapy. We retained 137 patients with recorded pre-treatment leukocyte and neutrophil levels for associated analysis and 114 patients with recorded lymphocyte levels during radiation and associated analysis. Multivariate survival analyses were done with Cox regression. Results The radiotherapy type (IMRT vs. IMPT) was not associated with lymphopenia (grade 3 P > .99; grade 4 P = .55). In univariate analyses, poor overall survival was associated with pretreatment neutrophilia (hazard ratio [HR] 5.58, 95% confidence interval [CI] 1.99-15.7, P = .001), pretreatment leukocytosis (HR 4.85, 95% CI 1.73-13.6, P = .003), grade 4 lymphopenia during radiotherapy (HR 3.28, 95% CI 1.14-9.44, P = .03), and possibly smoking status >10 pack-years (HR 2.88, 95% CI 1.01-8.18, P = .05), but only T status was possibly significant in multivariate analysis (HR 2.64, 95% CI 0.99-7.00, P = .05). Poor progression-free survival was associated with pretreatment leukocytosis and T status in univariate analysis, and pretreatment neutrophilia and advanced age on multivariate analysis. Conclusions Treatment modality did not affect blood counts during radiotherapy. Pretreatment neutrophilia, pretreatment leukocytosis, and grade 4 lymphopenia during radiotherapy were associated with worse outcomes after, but establishing causality will require additional work with increased statistical power.

Abstract
Background Given the potential for older patients to experience exaggerated toxicity and symptoms, this study was performed to characterize patient reported outcomes in older patients following definitive radiation therapy (RT) for oropharyngeal cancer (OPC). Methods Cancer-free head and neck cancer survivors (>6 months since treatment completion) were eligible for participation in a questionnaire-based study. Participants completed the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN). Those patients ≥65 years old at treatment for OPC with definitive RT were included. Individual and overall symptom severity and clinical variables were analyzed. Results Of the 79 participants analyzed, 82% were male, 95% white, 41% T3/4 disease, 39% RT alone, 27% induction chemotherapy, 52% concurrent, and 18% both, and 96% IMRT. Median age at RT was 71 yrs. (range: 65–85); median time from RT to MDASI-HN was 46 mos. (2/3 > 24 mos.). The top 5 MDASI-HN items rated most severe in terms of mean (±SD) ratings (0–10 scale) were dry mouth (3.48 ± 2.95), taste (2.81 ± 3.29), swallowing (2.59 ± 2.96), mucus in mouth/throat (2.04 ± 2.68), and choking (1.30 ± 2.38) reported at moderate-severe levels (≥5) by 35, 29, 29, 18, and 13%, respectively. Thirty-nine % reported none (0) or no more than mild (1–4) symptoms across all 22 MDASI-HN symptoms items, and 38% had at least one item rated as severe (≥7). Hierarchical cluster analysis resulted in 3 patient groups: 1) ~65% with ranging from none to moderate symptom burden, 2) ~35% with moderate-severe ratings for a subset of classically RT-related symptoms (e.g. dry mouth, mucus, swallowing) and 3) 2 pts. with severe ratings of most items. Conclusions The overall long-term symptom burden seen in this older OPC cohort treated with modern standard therapy was largely favorable, yet a higher symptom group (~35%) with a distinct pattern of mostly local and classically RT-related symptoms was identified.

Abstract
OBJECTIVES/HYPOTHESIS To evaluate the long-term disease control, survival, and complications after definitive radiotherapy (RT) alone or combined with adjuvant chemotherapy with or without planned neck dissection for base of tongue squamous cell carcinoma (SCC). STUDY DESIGN We retrospectively reviewed the medical records of 467 patients treated at the University of Florida with definitive RT alone or combined with adjuvant chemotherapy between 1964 and 2011 for base of tongue SCC. METHODS Median follow-up was 5.6 years. Median total dose to the primary site was 74.4 Gy. Eighty-seven patients (19%) were treated with once-daily fractionation, and 380 (81%) received altered fractionation schedules. Intensity-modulated RT was used in 128 patients (27%). Chemotherapy was administered to 173 (37%) patients. Planned neck dissection after RT was performed in 226 patients (48%). Data regarding p16 pathway activation were available for 25 patients. RESULTS At 5 years, the local, local-regional, and regional control rates were 85.5%, 80.0%, and 90.0%, respectively. The 5-year overall, cause-specific, and distant metastasis-free survival rates were 59.1%, 71.5%, and 84.1%, respectively. Sixty-four patients (14%) developed one or more severe late complications. Fifty patients (11%) required late gastrostomy tube placement. CONCLUSIONS This study supports the continued use of RT alone or combined with adjuvant chemotherapy for patients with base of tongue SCC, as this treatment yields high rates of cause-specific survival and disease control, with a relatively low rate of late complications.

[PMID: 27342249 PMCID: PMC5474304 DOI: 10.1016/j.radonc.2016.05.022] [Citation(s) in RCA: 157] [Impact Index Per Article: 19.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 05/17/2016] [Accepted: 05/18/2016] [Indexed: 11/16/2022]
Abstract
BACKGROUND Owing to its physical properties, intensity-modulated proton therapy (IMPT) used for patients with oropharyngeal carcinoma has the ability to reduce the dose to organs at risk compared to intensity-modulated radiotherapy (IMRT) while maintaining adequate tumor coverage. Our aim was to compare the clinical outcomes of these two treatment modalities. METHODS We performed a 1:2 matching of IMPT to IMRT patients. Our study cohort consisted of IMPT patients from a prospective quality of life study and consecutive IMRT patients treated at a single institution during the period 2010-2014. Patients were matched on unilateral/bilateral treatment, disease site, human papillomavirus status, T and N status, smoking status, and receipt of concomitant chemotherapy. Survival analyzes were performed using a Cox model and binary toxicity endpoints using a logistic regression analysis. RESULTS Fifty IMPT and 100 IMRT patients were included. The median follow-up time was 32months. There were no imbalances in patient/tumor characteristics except for age (mean age 56.8years for IMRT patients and 61.1years for IMPT patients, p-value=0.010). Statistically significant differences were not observed in overall survival (hazard ratio (HR)=0.55; 95% confidence interval (CI): 0.12-2.50, p-value=0.44) or in progression-free survival (HR=1.02; 95% CI: 0.41-2.54; p-value=0.96). The age-adjusted odds ratio (OR) for the presence of a gastrostomy (G)-tube during treatment for IMPT vs IMRT were OR=0.53; 95% CI: 0.24-1.15; p-value=0.11 and OR=0.43; 95% CI: 0.16-1.17; p-value=0.10 at 3months after treatment. When considering the pre-planned composite endpoint of grade 3 weight loss or G-tube presence, the ORs were OR=0.44; 95% CI: 0.19-1.0; p-value=0.05 at 3months after treatment and OR=0.23; 95% CI: 0.07-0.73; p-value=0.01 at 1year after treatment. CONCLUSION Our results suggest that IMPT is associated with reduced rates of feeding tube dependency and severe weight loss without jeopardizing outcome. Prospective multicenter randomized trials are needed to validate such findings.

Dosimetric advantages of intensity-modulated proton therapy for oropharyngeal cancer compared with intensity-modulated radiation: A case-matched control analysis. Med Dosim 2016; 41:189-94. [PMID: 27158021 DOI: 10.1016/j.meddos.2016.01.002] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2015] [Accepted: 01/20/2016] [Indexed: 11/25/2022]
Abstract
A potential advantage of intensity-modulated proton therapy (IMPT) over intensity-modulated (photon) radiation therapy (IMRT) in the treatment of oropharyngeal carcinoma (OPC) is lower radiation dose to several critical structures involved in the development of nausea and vomiting, mucositis, and dysphagia. The purpose of this study was to quantify doses to critical structures for patients with OPC treated with IMPT and compare those with doses on IMRT plans generated for the same patients and with a matched cohort of patients actually treated with IMRT. In this study, 25 patients newly diagnosed with OPC were treated with IMPT between 2011 and 2012. Comparison IMRT plans were generated for these patients and for additional IMRT-treated controls extracted from a database of patients with OPC treated between 2000 and 2009. Cases were matched based on the following criteria, in order: unilateral vs bilateral therapy, tonsil vs base of tongue primary, T-category, N-category, concurrent chemotherapy, induction chemotherapy, smoking status, sex, and age. Results showed that the mean doses to the anterior and posterior oral cavity, hard palate, larynx, mandible, and esophagus were significantly lower with IMPT than with IMRT comparison plans generated for the same cohort, as were doses to several central nervous system structures involved in the nausea and vomiting response. Similar differences were found when comparing dose to organs at risks (OARs) between the IMPT cohort and the case-matched IMRT cohort. In conclusion, these findings suggest that patients with OPC treated with IMPT may experience fewer and less severe side effects during therapy. This may be the result of decreased beam path toxicities with IMPT due to lower doses to several dysphagia, odynophagia, and nausea and vomiting-associated OARs. Further study is needed to evaluate differences in long-term disease control and chronic toxicity between patients with OPC treated with IMPT in comparison to those treated with IMRT.

Clinical results of definitive intensity-modulated radiation therapy for oropharyngeal cancer: retrospective analysis of treatment efficacy and safety. Jpn J Clin Oncol 2015; 46:78-85. [PMID: 26496935 DOI: 10.1093/jjco/hyv157] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2015] [Accepted: 09/25/2015] [Indexed: 01/07/2023] Open
Abstract
OBJECTIVE To evaluate the clinical outcomes of intensity-modulated radiotherapy for patients with oropharyngeal carcinoma. METHODS Ninety-three oropharyngeal carcinoma patients histopathologically diagnosed with squamous cell carcinoma and treated with definitive intensity-modulated radiotherapy using helical tomotherapy between January 2006 and December 2013 were analyzed. Planning target volume primary and involved nodes was delivered 66-70 Gy at 2 Gy per fraction, while planning target volume prophylactic was delivered 54 Gy using the simultaneous integrated boost technique. RESULTS The median follow-up period among the surviving patients was 40 months (range, 13-96). There were 76 males and 17 females with a median age of 60 years (range, 34-80). The disease was Stage II in 13%, Stage III in 10% and Stage IV in 77% of patients. Ninety-two patients received chemotherapy (99%); 68 patients received induction chemotherapy (73%), while 21 received concurrent chemotherapy (23%). The 3-year overall survival, progression-free survival and locoregional control rates were 80, 68 and 79%, respectively. Multivariate analysis identified an advanced T-category (T3-4), having double cancer, and smoking habit as significantly unfavorable factors for overall survival, progression-free survival and both progression-free survival and locoregional control, respectively. Only two patients who achieved disease control required percutaneous endoscopic gastrostomy tubes in the last follow-up. The rate of Grade 2 xerostomia at 2 years was 23%. CONCLUSIONS Intensity-modulated radiotherapy using helical tomotherapy for patients with oropharyngeal carcinoma provided not only sufficient efficacy, but also preserved parotid function.

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
Oropharyngeal carcinomas, contrary to other head and neck carcinomas are of increasing frequency, mostly due to a frequent association with human papillomavirus infection. Pluridisciplinary management is necessary. New techniques as transoral surgery or intensity-modulated radiation therapy have the potential to reduce toxicities and morbidity while offering equivalent local control rates. Early stages may be treated with single modality treatment (surgery or radiotherapy) with five-year overall survival rate exceeding 80%. Advanced stages need therapeutic associations and five-years survival rates are inferior to 40%.

Abstract
Despite recent advancements in multidisciplinary treatments, the overall survival and quality of life of patients with advanced head and neck squamous cell carcinoma (HNSCC) have not improved significantly over the past decade. Molecular targeted therapies, which have been addressed and advanced by the concept of “oncogene addiction”, have demonstrated only limited successes so far. To explore a novel clue for clinically effective targeted therapies, we analyzed the molecular circuitry of HNSCC through the lens that HNSCC is an evolving system. In the trajectory of this somatic evolution, HNSCC acquires biological robustness under a variety of selective pressures including genetic, epigenetic, micro‐environmental and metabolic stressors, which well explains the major mechanism of “escaping from oncogene addiction”. On the other hand, this systemic view appears to instruct us approaches to target latent vulnerability of HNSCC that is masked behind the plasticity and evolvability of this complex adaptive system. There is an urgent need to develop a novel conceptual framework for the treatment of HNSCC. The biological robustness of HNSCC was analyzed through a somatic evolution model. This model well explains the mechanism of “escaping from oncogene addiction”. We discuss about the possible approaches to target vulnerability of evolving HNSCC.

Abstract
OBJECTIVE A temporal Monte Carlo tumour growth and radiotherapy effect model (HYP-RT) simulating hypoxia in head and neck cancer has been developed and used to analyse parameters influencing cell kill during conventionally fractionated radiotherapy. The model was designed to simulate individual cell division up to 10(8) cells, while incorporating radiobiological effects, including accelerated repopulation and reoxygenation during treatment. METHOD Reoxygenation of hypoxic tumours has been modelled using randomised increments of oxygen to tumour cells after each treatment fraction. The process of accelerated repopulation has been modelled by increasing the symmetrical stem cell division probability. Both phenomena were onset immediately or after a number of weeks of simulated treatment. RESULTS The extra dose required to control (total cell kill) hypoxic vs oxic tumours was 15-25% (8-20 Gy for 5 × 2 Gy per week) depending on the timing of accelerated repopulation onset. Reoxygenation of hypoxic tumours resulted in resensitisation and reduction in total dose required by approximately 10%, depending on the time of onset. When modelled simultaneously, accelerated repopulation and reoxygenation affected cell kill in hypoxic tumours in a similar manner to when the phenomena were modelled individually; however, the degree was altered, with non-additive results. Simulation results were in good agreement with standard linear quadratic theory; however, differed for more complex comparisons where hypoxia, reoxygenation as well as accelerated repopulation effects were considered. CONCLUSION Simulations have quantitatively confirmed the need for patient individualisation in radiotherapy for hypoxic head and neck tumours, and have shown the benefits of modelling complex and dynamic processes using Monte Carlo methods.

Abstract
PURPOSE S-1 is an oral fluoropyrimidine. The purpose of this study was to review the clinical outcomes of S-1 with concurrent radiotherapy for patients with oropharyngeal cancer. MATERIALS AND METHODS Between 2002 and 2007, 38 patients with oropharyngeal cancer treated concurrently with S-1 and definitive radiotherapy were reviewed. The clinical stage was Stage I in 4 patients, Stage II in 7, Stage III in 7, and Stage IV in 20. S-1 was administered orally twice daily for 4 consecutive weeks followed by a 2-week drug withdrawal. The initial dose of S-1 was 65 mg/m(2)/day. All patients were treated using three-dimensional conformal radiotherapy with a median total dose of 65.1 Gy (range, 60.0-71.0 Gy). Clinical outcomes and major acute toxicities were analyzed based on medical records and clinical follow-up. RESULTS With a median follow-up time of 33 months, the 3-year estimates of local-regional control, distant metastases-free survival, disease-free survival, and overall survival for all patients were 75%, 80%, 65%, and 80%, respectively. The 3-year estimates of local-regional control according to stage were 100% for Stages I and II, 86% for Stage III, and 56% for Stage IV. The rate of ≥ Grade 3 acute mucositis was 32%, and the rate of ≥ Grade 3 hematological toxicities was 8%. No other severe toxicities were observed. CONCLUSIONS Concurrent chemoradiotherapy with S-1 was found to be effective, especially for early disease. The treatment-related toxicities were acceptable, and the incidence of myelotoxicity was low. Further study must be carried out to compare with other chemotherapy regimens.

Abstract
OBJECTIVE: To compare the therapeutic role of surgery followed by radiotherapy (OPRT) and concurrent chemoradiotherapy (CCRT) in patients with early T (T1/T2) and advanced N (N2/N3) stage tonsillar squamous cell carcinoma. STUDY DESIGN: Historical cohort study. SETTING: A tertiary hospital. SUBJECTS AND METHODS: The medical records of 42 patients who met the eligible criteria (24 patients were treated by OPRT, 18 patients by CCRT) were reviewed. RESULTS: Mean overall survival (OS) and disease-free survival (DFS) were 49.0 months and 43.0 months in OPRT group, respectively, and 39.6 months and 35.0 months in CCRT group, respectively ( P = 0.18 for OS, P = 0.29 fr DFS between the two groups). There was also no significant difference in survival estimates between OPRT and CCRT group in terms of two-year OS ( P = 0.18) and two-year DFS ( P = 0.45). In the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, the scores for global health status and symptom scales did not differ between the two groups. However, the OPRT group reported better functional scales and significantly higher scores for cognitive ( P = 0.008) and social function ( P = 0.03). Among single items, a significantly lower score for insomnia ( P = 0.007) was noted in the OPRT group. In EORTC QLQ-H&N35 modules, there were no significantly different scales between the two groups except scores for nutritional supplements, in which the OPRT group presented lower symptom scores ( P = 0.02). CONCLUSION: OPRT could be still a viable option for managing selected cases of advanced oropharyngeal cancer because one can expect comparable therapeutic outcome as well as quality of life.

Abstract
Proton beam radiation therapy (PBRT) has unique physical properties (e.g., Bragg Peak) that limit the amount of normal tissue irradiated in the head and neck region while maximizing the radiation delivered to the tumor. Radiation therapy is commonly used in both the primary and adjuvant setting for many head and neck malignancies. Limiting the unnecessary radiation to normal tissues within the head and neck region can result in a profound improvement in quality of life during and after treatment. Although PBRT was initially developed in the 1950s, recent technological advances have permitted the development of hospital-based facilities for proton delivery. PBRT has been shown to improve outcomes for patients with sinonasal tumors, chordomas, chondrosarcomas, ocular, and periocular malignancies. Further development of intensity-modulated proton therapy will permit comprehensive treatment for head and neck tumors.

Abstract
BACKGROUND Environmental exposures to tobacco, alcohol, human papillomavirus (HPV) and/or Epstein-Barr virus (EBV), all of which can perturb multiple cell cycle proteins or tumor suppressors, have been implicated in the pathogenesis of different subsets of head and neck cancers. The aim of this study was to investigate to which extent the virus infection by itself, and/or the altered cell cycle proteins, contributes to prognosis in locally advanced tonsillar squamous cell carcinomas (TSCCs) treated with concurrent chemoradiotherapy (CCRT) alone. METHODS Serial tumor tissue arrays from archival samples were tested for the presence of HPV genome integration or EBV episome by means of DNA sequencing, real-time polymerase chain reaction (PCR), and in situ hybridization. Alterations of cell cycle proteins (p53, pRb, and p21) were evaluated by immunohistochemical staining. The association of viral presence with altered cell cycle proteins was correlated to clinical outcomes. RESULTS Of the 46 patients with the same T2N2bM0 stage IVA among consecutive patients with TSCC, 23 (50%) had integrated HPV DNA and only 1 (2%) had EBV episome. The HPV types detected were almost all HPV-16. A reduced expression pattern of p53, pRb, and p21 was noted in HPV-positive tumors, and the incremental number of alterations in the 3 proteins was significantly associated with HPV-negative tumors. The presence or absence of HPV together with the number of altered expression of the 3 cell cycle markers resulted in further identification of 4 biologically and clinically distinct subgroups with different outcomes after CCRT. CONCLUSIONS Use of combined biomarkers of oncogenic HPV and tumor suppressors of p53, pRb, and p21 in advanced TSCC provides prognostic molecular classification superior to the TNM stage system and identifies low-risk patients for organ preservation by CCRT alone and high-risk patients who might benefit from planned tonsillectomy and neck dissection before or after CCRT.

Abstract
OBJECTIVES Oropharyngeal cancers represent 10%-15% of all head and neck cancers. At presentation 60%-70% will have advanced-stage disease with a high incidence of neck metastases. Primary treatment employing radiotherapy, with or without chemotherapy, is widely prescribed. The aim of this study is to analyze the outcome of definitive surgical management of T1-T2 cancers of the oropharynx. METHODS We conducted a retrospective cohort study of patients treated at the Sydney Head and Neck Cancer Institute. Patients with previously untreated squamous cell carcinoma (SCC) of the oropharynx were included according to the TNM stage of the disease as follows: T1 or T2, any N-stage, and M0. All patients underwent definitive primary surgical management. Primary analysis endpoints were locoregional control rates and disease-specific survival. RESULTS Ninety-two patients were identified, of which 26 were T1 and 66 were T2. Forty-four patients had clinical neck disease, and 57 had postoperative radiotherapy. The results showed no significant difference between the T1 and T2 groups with respect to local control or treatment type; however, advanced-stage neck disease was associated with a worse prognosis. The 5-year disease-specific survival was 83% and local control rate was 87%. Ultimately, 25 of the 92 patients had treatment failure (27%). CONCLUSIONS Selected patients with early-stage primary cancers of the oropharynx may be effectively treated with definitive primary surgery.

Prognostic significance of tumor hypoxia inducible factor-1alpha expression for outcome after radiotherapy in oropharyngeal cancer. Int J Radiat Oncol Biol Phys 2008; 72:1551-9. [PMID: 19028277 DOI: 10.1016/j.ijrobp.2008.07.051] [Citation(s) in RCA: 46] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2008] [Revised: 07/28/2008] [Accepted: 07/31/2008] [Indexed: 12/27/2022]
Abstract
PURPOSE Head-and-neck squamous cell carcinoma (HNSCC) represents a heterogeneous group of patients in terms of subsite, treatment, and biology. Currently most management decisions are based on clinical parameters with little appreciation of patient differences in underlying tumor biology. We investigated the prognostic significance of clinicopathologic features and tumor hypoxia-inducible factor-1alpha (HIF-1alpha) expression in a homogeneous series of patients who underwent radiotherapy. METHODS AND MATERIALS An audit identified 133 consecutive patients with histologically proven squamous cell carcinoma of the tonsil or tongue base. All patients received primary radiotherapy between 1996 and 2001. Tumor HIF-1alpha expression was examined in 79 patients. RESULTS Features associated with poor locoregional control were low Hb level (p = 0.05) and advancing T (p = 0.008), N (p = 0.03), and disease (p = 0.008) stage. HIF-1alpha expression was a more significant adverse prognostic factor in the tonsil (hazard ratio [HR], 23.1; 95% confidence interval [CI]. 3.04-176.7) than the tongue-base tumor (HR, 2.86; 95% CI, 1.14-7.19) group (p = 0.03, test for interaction). High tumor HIF-1alpha expression was associated with low blood Hb levels (p = 0.03). In a multivariate analysis HIF-1alpha expression retained prognostic significance for locoregional control (HR, 7.10; 95% CI, 3.07-16.43) and cancer-specific survival (HR, 9.19; 95% CI, 3.90-21.6). CONCLUSIONS There are significant differences in radiation therapy outcome within a homogeneous subsite of the oropharynx related to molecular marker expression. The work highlights the importance of studying homogeneous groups of patients in HNSCC, and the complex interrelationships between tumor biology and clinicopathologic factors. The establishment of tumor-type specific markers would represent a major advance in this area.

Abstract
HYPOTHESIS To define the role of surgical staging in limited (T1-2, N0-1) oropharyngeal squamous cell cancers. STUDY DESIGN Retrospective. METHODS Forty-nine limited oropharyngeal squamous cell cancers of the tonsil, tongue base, or posterior pharyngeal wall-treated surgically were identified. RESULTS Thirty-five percent were cT1 and 65% were cT2 tumors although 58% were cN0 and 42% were cN1. Forty-six patients underwent neck dissections. Surgical staging altered T-stage in 26% (13/49), nodal status in 23% (11/46), and clinical staging in 40% (20/49) of patients. Among 35 disease-free patients, 28% (4/20) of stage I/II patients received postoperative radiation and chemotherapy was avoided in 80% (12/15) of stage III patients. T1 tumors seemed to have better outcomes (P = .06). The 3 year disease-free survival and 5 year overall survival was 85% and 83%, respectively. CONCLUSIONS Surgical staging identifies patients in whom intensification of treatment with chemotherapy can be most appropriately applied, and enables de-intensification of therapy in pathology confirmed stage I/II disease.

Abstract
PURPOSE To evaluate the prognostic factors for the risk of distant metastases after postoperative radiotherapy for laryngeal cancer. MATERIAL AND METHODS Medical records of 267 patients cancer treated between 1997 and 2003 were analyzed. All pts had locally advanced squamous cell laryngeal cancer treated with surgery and postoperative radiotherapy. Metastasis Free Survival was analyzed using Kaplan-Meier method. A multivariate Cox proportional hazard model and logistic regression model was used to evaluated influence of the following variables on MFS and the ultimate risk of metastases: age, sex, localization, TN stage, HGB before and at the end radiotherapy, total radiation dose, dose per fraction, overall treatment time, interval surgery-radiation time, pathological margins and positive nodes in surgical specimen. RESULTS The crude incidence of distant metastases was 12% (33/267 pts). One year, 3-year, 5-year actuarial metastases free survival were 95%, 85% and 84% respectively. The lungs and bones were the most common sites of metastases (58% and 33% respectively), whereas metastases to liver (6%) and brain (3%) were rare. Localization of cancer (glottic vs. supraglottic) and number of positive lymph nodes at pathological staging significantly and independently affected MFS. CONCLUSIONS Number of positive lymph nodes in pathological specimen and site of primary cancer (glottic vs. supraglottic) significantly and independently predict a risk of distant metastases in combined modality treatment for laryngeal cancer.

Chemoradiation for advanced head and neck cancer: potential for improving results to match those of current treatment modalities for early-stage tumors--long-term results of hyperfractionated chemoradiation with carbogen breathing and anemia correction with erythropoietin. Int J Radiat Oncol Biol Phys 2007; 70:1382-8. [PMID: 18037586 DOI: 10.1016/j.ijrobp.2007.08.068] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2007] [Revised: 08/10/2007] [Accepted: 08/10/2007] [Indexed: 11/21/2022]
Abstract
PURPOSE To attempt to improve results of chemoradiation for head and neck cancer. METHODS AND MATERIALS From March 1996 to April 2007, 98 patients with head and neck cancer (15 Stage III and 83 Stage IV) were treated with a twice-daily hyperfractionated schedule. Eleven patients presented with N0, 11 with N1, 13 with N2A, 17 with N2B, 24 with N2C, and 22 with N3. Each fraction of treatment consisted of 5 mg/m(2) of carboplatin plus 115 cGy with carbogen breathing. Treatment was given 5 days per week up to total doses of 350 mg/m(2) of carboplatin plus 8050 cGy in 7 weeks. Anemia was corrected with erythropoietin. RESULTS Ninety-six patients tolerated the treatment as scheduled. All patients tolerated the planned radiation dose. Local toxicity remained at the level expected with irradiation alone. Chemotherapy toxicity was moderate. Ninety-seven complete responses were achieved. After 11 years of follow-up (median, 81 months), actuarial locoregional control, cause-specific survival, overall survival, and nodal control rates at 5 and 10 years were, respectively, 83% and 83%, 68% and 68%, 57% and 55%, and 100% and 100%. Median follow-up of disease-free survivors was 80 months. No significant differences in survival were observed between the different subsites or between the pretreatment node status groups (N0 vs. N+, N0 vs. N1, N0 vs. N2A, N0 vs. N2B, N0 vs. N2C, and N0 vs. N3). CONCLUSIONS Improving results of chemoradiation for advanced head and neck cancer up to the level obtained with current treatments for early-stage tumors is a potentially reachable goal.

Abstract
BACKGROUND We reviewed the outcomes of oropharyngeal squamous cell carcinoma treated with external beam radiation and interstitial brachytherapy. METHODS Ninety patients with squamous cell carcinoma of the oropharynx were treated with interstitial brachytherapy at the University of Utah between 1984 and 2001. Seventy-two patients received external beam radiotherapy (EBRT) followed by brachytherapy boost, 11 had surgery followed by EBRT and brachytherapy, 4 had surgery and brachytherapy, and 3 were treated with brachytherapy alone. Median doses for EBRT and brachytherapy were 50 and 24 Gy, respectively. RESULTS Median follow-up after brachytherapy was 48.3 months for all patients. Five-year local control, disease-free survival, and overall survival were 76%, 61%, and 55%. For T1, T2, T3, and T4, 5-year local control rates were 83%, 79%, 79%, and 64%, respectively. Severe complications occurred in 13 patients, including 2 treatment-related deaths. CONCLUSIONS EBRT combined with interstitial brachytherapy provide good local control rates for locally advanced oropharyngeal squamous cell carcinoma.

Abstract
BACKGROUND The purpose of this study was to assess the ability of intensity-modulated radiation therapy (IMRT) to achieve favorable disease-control rates while minimizing parotid gland doses in patients treated for small primary tumors of the oropharynx. METHODS AND MATERIALS We retrospectively identified all patients who received IMRT as treatment for a small (<4 cm) primary tumor of the oropharynx between October 2000 and June 2002. Tumor characteristics, IMRT parameters, and patient outcomes were assessed. RESULTS Fifty-one patients met the criteria for our study. All patients had treatment to gross disease with margin (CTV1), and all but 1 had treatment to the bilateral necks. The most common treatment schedule (39 patients) was a once-daily fractionation of prescribed doses of 63-66 Gy to the CTV1 and 54 Gy to subclinical sites, delivered in 30 fractions. Twenty-one patients (40%) had gastrostomy tubes placed during therapy; in 4 patients, the tube remained in place for more than 6 months after completion of IMRT. The median follow-up was 45 months. The 2-year actuarial locoregional control, recurrence-free, and overall survival rates were 94%, 88%, and 94%, respectively. CONCLUSIONS These preliminary data suggest that treatment with IMRT results in favorable locoregional control of small primary oropharynx tumors. IMRT did not appear to have a more favorable acute toxicity profile in this group with respect to the use of a feeding tube; however, the mean dose of radiation delivered to the parotid gland by IMRT was decreased, because 95% of patients had a mean dose of <30 Gy to at least one gland.

Abstract
The concept of postradiation sarcoma is widely appreciated, however carcinomas arising in previously irradiated fields, the putative "postradiation carcinoma," are less well understood. Fifteen patients who developed gynecological malignancies after pelvic radiation therapy were studied. Five of these patients had HPV-related tumors both pre- and post- irradiation. Ten were irradiated for cervical cancer, one for endometrial carcinoma, one for vulvar carcinoma, one for colon cancer and 2 for benign conditions. The mean and median latent periods from the initiation of radiation therapy to the development of the second malignancy were 22.8 and 19 years, respectively (22.4 and 19.5 years, respectively, for non-HPV-related cancers; 24 and 18 years for HPV-related cancers). The "postradiation" malignancies included 2 ovarian carcinomas, 5 vaginal carcinomas (3 invasive, 2 in situ), 4 endometrial carcinomas, one cervical carcinoma, one vulvar carcinoma, one distal urethral carcinoma, and one pelvic carcinoma of unclear primary site. Gynecological carcinomas may occur many years after pelvic irradiation. Although the evidence for a causative role is circumstantial, these tumors appear to have a similar latent period as postradiation sarcomas.

Abstract
The length and quality of head and neck cancer survivorship continues to improve. Radiotherapy has been central to this process through advances in treatment technology, fractionation schemas, radiosensitizing chemotherapy, and surgical technique. The future of head and neck radiotherapy looks brighter still with progress in radiosensitizing biologic therapy, molecular characterization, functional imaging, and rehabilitative strategies fast approaching. Head and neck cancer, a disease once fraught with nihilism and failure, is evolving into a major success story of multidisciplinary solid tumor management. Continued dedication and work on the part of provider and patient alike will be required to make this promise a reality.

Abstract
BACKGROUND Our center sought to implement a simple chemoradiotherapy schedule for patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) with minimal toxicity to achieve rates of overall survival comparable to other schedules. METHODS The chemoradiotherapy schedule consisted of daily radiation to 70 Gy over 7 weeks with concurrent cisplatin 20 mg/m(2) during days 1 to 4 of weeks 1 and 5. Acute and late toxicities were recorded according to the Radiation Therapy Oncology Group (RTOG) and common toxicity criteria (CTC) grading. The overall, disease-specific, and locoregional recurrence-free survival were calculated using the STATA statistics package. Possible factors influencing these endpoints were analyzed. RESULTS Fifty-seven patients were treated, and 56 patients were evaluable for follow-up. Median follow-up of alive patients was 16.1 months. There was an 82% complete response rate to chemoradiotherapy. The 2-year Kaplan-Meier overall, disease-specific, and locoregional recurrence-free survival rates were 62%, 67%, and 63%. Acute grade 3 and 4 radiation toxicity was noted in 61% and 2%, respectively. Grade 3 or 4 hematologic toxicity was noted in 7% of patients. Factors influencing overall survival included: Karnofsky performance status, receiving more than 50% of planned chemotherapy, age, and initial hemoglobin level. CONCLUSION This regimen is tolerable and achieves overall survival and locoregional control rates comparable to other chemoradiotherapy schedules.

Abstract
BACKGROUND Unresectable carcinomas of the oropharynx and hypopharynx still have a poor long-term prognosis. Following a previous phase II study, this phase III multicenter trial was conducted between November 1997 and March 2002. METHODS Nontreated, strictly unresectable cases were eligible. Twice-daily radiation: two fractions of 1.2 Gy/day, 5 days per week, with no split (D1-->D46). Total tumor doses: 80.4 Gy/46 day (oropharynx), 75.6 Gy/44 day (hypopharynx). Chemotherapy (arm B): Cisplatin 100 mg/m2 (D1, D22, D43); 5FU, continuous infusion (D1-->D5), 750 mg/m2/day cycle 1; 430 mg/m2/day cycles 2 and 3. RESULTS A total of 163 evaluable patients. Grade 3-4 acute mucositis 82.6% arm B/69.5% arm A (NS); Grade 3-4 neutropenia 33.3% arm B/2.4% arm A (p < 0.05). Enteral nutrition through gastrostomy tube was more frequent in arm B before treatment and at 6 months (p < 0.01). At 24 months, overall survival (OS), disease-free survival (DFS), and specific survival (SS) were significantly better in arm B. OS: 37.8% arm B vs. 20.1% arm A (p = 0.038); DFS: 48.2% vs. 25.2% (p = 0.002); SS: 44.5% vs. 30.2% (p = 0.021). No significant difference between the two arms in the amount of side effects at 1 and 2 years. CONCLUSION For these unresectable cases, chemoradiation provides better outcome than radiation alone, even with an "aggressive" dose-intensity radiotherapy schedule.

Abstract
PURPOSE To evaluate the role of interstitial brachytherapy as an exclusive radiotherapy modality for primary T1-T2 squamous cell carcinomas (SCC) of the velotonsillar area. METHODS AND MATERIALS Between 1992 and 2000, 44 patients with T1-T2 SCC of the tonsil (n = 36) and soft palate (n = 8) were treated to the primary with brachytherapy alone (37 patients) or after a limited resection (7 patients). Eight patients had prior external beam radiation therapy (EBRT) for previous head-and-neck carcinoma. Nineteen patients had initial neck dissection. The mean brachytherapy dose was 58.7 Gy, and the mean reference dose rate and Ir-192 linear activity were 58.2 cGy/h and 1.51 mCi/cm respectively. RESULTS With a 75-month median follow-up, 1 patient recurred locally. Isolated nodal relapses occurred in 4 patients, none of whom had initial neck dissection, and salvage therapy was successful in 2. Five-year overall and progression-free survival rates were 76% and 68%, respectively. Full-course radiation therapy was possible in 7 of 12 patients who developed a second primary head-and-neck carcinoma. Late toxicity was limited to 6 mild soft-tissue necroses, and was significantly associated with previous surgery to the primary and high linear activity. CONCLUSIONS Exclusive brachytherapy for T1-T2 velotonsillar carcinomas is safe and effective, and permits definitive reirradiation for a second head-and-neck cancer. Initial neck dissection should be performed for optimal selection for exclusive brachytherapy.

Abstract
PURPOSE OF REVIEW The management of oropharyngeal cancers continues to evolve. Due to the functional consequences of surgery, organ preservation strategies with radiation combined with chemotherapy have been developed. Newer strategies to diminish the acute and late toxicities and improve the functional outcome of organ preservation strategies are being developed. Intensity-modulated radiation therapy is a relatively new, advanced form of radiation therapy that is being studied in an effort to improve local control rates and minimize the late effects of treatment. RECENT FINDINGS Several recent studies have further supported the role for radiation therapy and chemotherapy as part of organ preservation strategies for cancers of the oropharynx. With the intensification of treatment, however, toxicities and functional impairment occur and have not been well documented in the past. Several recent studies report on the toxicities of traditional treatment methods. In addition, data show that intensity-modulated radiation therapy may be superior in terms of limiting toxicity compared with standard radiation therapy techniques. The integration of intensity-modulated radiation therapy with chemotherapeutic and radioprotective agents to further improve the therapeutic window for radiation therapy is being actively pursued. SUMMARY This paper reviews recent advances in radiotherapy for oropharynx cancer and the use of intensity-modulated radiation therapy.

Abstract
PURPOSE For the surgical treatment of osteoradionecrosis after multimodal therapy of head-and-neck cancers, free vascular bone grafts are used to reconstruct osseous structures in the previously irradiated graft bed. Reduced, or even absent osseous healing in the transition area between the vascular graft and the irradiated graft bed represents a clinical problem. Inflammatory changes and fibrosis lead to delayed healing, triggered by bone morphogentic protein 2/4 (BMP2/4) and transforming growth factor (TGF)-beta(1). Given the well-known fibrosis-inducing activity of TGF-beta(1), an osteoinductive effect has been reported for BMP2/4. However, the influence of irradiation (RT) on this cytokine expression remains elusive. Therefore, the aim of the present in vivo study was to analyze the expression of BMP2/4, TGF-beta(1), collagen I, and osteocalcin in the transition area between the bone graft and the graft bed after RT. METHODS AND MATERIALS Twenty Wistar rats (male, weight 300-500 g) were used in this study. A free vascular tibia graft was removed in all rats and maintained pedicled in the groin region. Ten rats underwent RT with 5 x 10 Gy to the right tibia, the remainder served as controls. After 4 weeks, the previously removed tibia grafts were regrafted into the irradiated (Group 1) and nonirradiated (Group 2) graft beds. The interval between RT and grafting was 4 weeks. After a 4-week osseous healing period, the bone grafts were removed, and the transition area between the nonirradiated graft and the irradiated osseous graft bed was examined histomorphometrically (National Institutes of Health imaging program) and immunohistochemically (avidin-biotin-peroxidase complex) for the expression of BMP2/4, TGF-beta(1), collagen I, and osteocalcin. RESULTS Absent or incomplete osseous healing of the graft was found in 9 of 10 rats after RT with 50 Gy and in 1 of 10 of the rats with nonirradiated osseous grafts. Histomorphometrically, the proportion of osseous healing in the transition area was 17% in Group 1 and 48% in Group 2 (p = 0.001). Compared with the nonirradiated rats, reduced enchondral and perichondral ossification was found in the healing area after RT, with a reduction of BMP2/4 and osteocalcin expression. TGF-beta(1) and collagen I expression in the transition area to the irradiated osseous graft bed was significantly increased compared with that in the nonirradiated osseous graft bed. CONCLUSION After RT, osseous healing of vascular bone grafts is significantly reduced and may be a result of radiation-induced inhibition of BMP2/4 and osteocalcin expression. In addition, induction of TGF-beta(1) and collagen I expression occurs. Because the effects of the TGF-beta superfamily are manifold and partially unknown, additional research directions could be in the exogenous application of BMP2/4 and inhibition of TGF-beta(1) by antibody treatment to search for appropriate therapeutic approaches for improving osseous healing in the irradiated graft bed.
