Abstract
OBJECTIVE(S) To assess the influence of treatment package time (TPT) on overall survival (OS) and event free survival (EFS) in oral cavity cancer (OCC) patients treated with surgery and adjuvant radiation therapy (RT) with or without concurrent chemotherapy (CHT). MATERIALS/METHODS 354 adult OCC patients treated at a single, high-volume center between 2012-2022 with various pathologic risk features were included. TPT was defined as days from surgery to RT completion. Kaplan-Meier estimates, log-rank p-values, univariable (UVA) and multivariable (MVA) Cox regression analyses were performed to determine the impact of TPT on OS and EFS, and the optimal TPT cutoff. RESULTS The optimal TPT cutoff was 105 days. TPT < 105 days was significantly associated with improved OS and EFS (p = 0.002 and p = 0.027, respectively) compared to TPT ≥ 105 days. On UVA, factors significantly associated with OS were TPT < 105 days, former/current smoker status, pathologic stage IV, positive perineural invasion (PNI), and extranodal extension (ENE) (all p < 0.05). On MVA for OS, TPT < 105 days, former/current smoker status, pathologic stage IV, and positive PNI (all p < 0.05) remained significant. Factors significantly associated with EFS on UVA were TPT < 105 days, former/current smoker status, pathologic stage IV, positive PNI or ENE, and concurrent CHT (all p < 0.05). On MVA, TPT < 105 days, pathologic stage IV, and positive PNI (all p < 0.05) remained significant. CONCLUSIONS In a large, homogenous cohort of OCCs, optimal TPT was <105 days, with TPT ≥ 105 days significantly associated with worse OS and EFS. Multidisciplinary coordination should analyze factors potentially contributing to treatment delay.

Abstract
Management of oral cavity squamous cell carcinoma (OSCC) involves a multidisciplinary team approach. Surgery is ideally the primary treatment option for nonmetastatic OSCC, and less invasive curative surgical approaches are preferred in early-stage disease to minimize surgical-related morbidity. For patients at high risk of recurrence, adjuvant treatment using radiation therapy or chemoradiation is often used. Systemic therapy may also be used in the neoadjuvant setting (for advanced-stage disease with the intent of mandibular preservation) or in the palliative setting (for nonsalvageable locoregional recurrence and/or distant metastases). Patient involvement in treatment decision is the key for patient-driven management, particularly in clinical situation with poor prognosis, for example, early postoperative recurrence before planned adjuvant therapy.

Abstract
Introduction Delays in commencing post‐operative radiation therapy (PORT) and prolongation of overall treatment times (OTT) are associated with reduced overall survival and higher recurrence rates in patients with head and neck squamous cell carcinoma (HNSCC). The objective of this study was to evaluate treatment delays, factors contributing to those delays and to explore strategies to mitigate them. Methods This retrospective study included patients with mucosal HNSCC at Townsville University Hospital treated with curative intent surgery and PORT between June 2011 and June 2019. The proportion of patients who experienced delays in commencing PORT (>6 weeks) and OTT were evaluated and reasons for these delays were explored. Results The study included 94 patients of which 70% experienced PORT delay. Surgery at an external facility (81% vs 56%, P = 0.006) and longer post‐operative length of stay (P = 0.011) were significantly associated with a higher incidence of PORT delay. Aboriginal and Torres Strait Islander patients had a higher rate of PORT delay (89% vs 68.2%, P = 0.198). Significant delays were noted from time of surgery to radiation oncology (RO) consult and from RO consult to commencement of radiation treatment. Conclusion This study demonstrates that the prevalence of PORT delay for patients with HNSCC remains high with room for improvement. Potential strategies to improve delays include developing effective care coordination, addressing specific needs of Indigenous patients, implementing reliable automated tracking and communication systems between teams and harnessing existing electronic referral systems.

Systematic review of postoperative therapy for resected squamous cell carcinoma of the head and neck: Executive summary of the American Radium Society appropriate use criteria. Head Neck 2021; 43:367-391. [PMID: 33098180 PMCID: PMC7756212 DOI: 10.1002/hed.26490] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 09/21/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND The aims of this systematic review are to (a) evaluate the current literature on the impact of postoperative therapy for resected squamous cell carcinoma of the head and neck (SCCHN) on oncologic and non-oncologic outcomes and (b) identify the optimal evidence-based postoperative therapy recommendations for commonly encountered clinical scenarios. METHODS An analysis of the medical literature from peer-reviewed journals was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Prospective studies and methodology-based systematic reviews and meta-analyses of postoperative therapy for SCCHN were identified by searching Medline (OVID) and EMBASE (Elsevier) using controlled vocabulary terms (ie, National Library of Medicine Medical Subject Headings [MeSH], EMTREE). Study screening and selection was performed with Covidence software and full-text review. The RAND/UCLA appropriateness method was used by the expert panel to rate the appropriate use of postoperative therapy, and the modified Delphi method was used to come to consensus. RESULTS A total of 5660 studies were identified and screened using the title and abstract, leading to 201 studies assessed for relevance using full-text review. After limitation to the eligibility criteria, 101 studies from 1977 to 2020 were identified, including 77 with oncologic endpoints and 24 with function and quality of life endpoints. All studies reported staging prior to the implementation of American Joint Committee on Cancer (AJCC-8). CONCLUSIONS Prospective clinical studies and systematic reviews identified through the PRISMA systematic review provided good evidence for consensus statements regarding the appropriate use of postoperative therapy for resected SCCHN. Further research is needed in domains where consensus by the expert panel could not be achieved for the appropriateness of specific postoperative therapeutic interventions.

Abstract
OBJECTIVE To compare the efficacy and tolerance of 7-days-a-week accelerated postoperative radiotherapy (p-CAIR) vs postoperative radio-chemotherapy (p-RTCT). METHODS Between September 2007 and October 2013, 111 patients were enrolled and randomly assigned to receive 63 Gy in 1.8 Gy fractions 7-days-a-week (n = 57, p-CAIR) or 63 Gy in 1.8 Gy fractions 5-days-a-week with concurrent cisplatin 80-100 mg per square meter of body-surface area on days 1, 22 and 43 of the radiotherapy course (p-RTCT). It represents approximately 40% of the intended trial size, that was closed prematurely due to slowing accrual. Only high-risk patients with squamous cell cancer of the oropharynx/oral cavity, considered fit for concurrent treatment were enrolled. RESULTS The rate of locoregional control (LRC) did not differ significantly between treatment arms (p = 0.18, HR = 0.56), 5 year LRC tended, however, to favour p-RTCT (81%) vs p-CAIR (62%). There was no difference in overall survival between treatment arms (p = 0.90, HR = 1.03).The incidence and severity of acute mucosal reactions and late reactions did not differ significantly between treatment arms. Haematological toxicity of p-RTCT was, however, considerably increased compared to p-CAIR. CONCLUSION Concurrent postoperative RTCT tended to improve locoregional control rate as compared to p-CAIR. This, however, did not transferred into improved overall survival. Postoperative RTCT was associated with a substantial increase in haematological toxicity that negatively affected treatment compliance in this arm. ADVANCES IN KNOWLEDGE To our knowledge, this is the first trial that compares accelerated radiotherapy and radio-chemotherapy in postoperative treatment for oralcavity/oropharyngeal cancer.

Abstract
INTRODUCTION Radiotherapy (RT) plays an important role in the treatment of patients with head and neck neoplasia, and is frequently used as postoperative adjuvant therapy. This study aimed to review the literature about timing factors that may influence the clinical outcomes of patients with advanced head and neck neoplasia treated with adjuvant RT. RESULTS Timing factors such as total treatment time, length of adjuvant RT, and the absence of interruptions during RT may influence the clinical outcome of these patients. CONCLUSIONS In the same way that certain tumor factors can affect the prognosis of patients with squamous cell carcinoma of the head and neck, some therapeutic timing factors are also prognostic factors and therefore, must be carefully orchestrated in order to avoid loss at therapeutic outcomes for these patients.

Accelerated Hyperfractionated Radiotherapy versus Conventional Fractionation Radiotherapy for Head and Neck Cancer: A Meta-Analysis of Randomized Controlled Trials. JOURNAL OF ONCOLOGY 2019; 2019:7634746.

Abstract
Objective The benefits of accelerated hyperfractionated radiotherapy (HART) and conventional fractionation radiotherapy (CFRT) in the treatment of head and neck cancer (HNC) remain controversial. In this study, we analyzed the therapeutic effects of these two treatment regimens to explore whether HART can improve the overall survival (OS) rate and locoregional control (LRC) rate in patients with HNC. Methods The PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for eligible studies. The OS rate and LRC rate were considered as the efficacy outcomes. I2 was used to test the heterogeneity among studies with a cutoff value of 50%. Potential publication bias was assessed by funnel plots and Egger's test. We also performed a sensitivity analysis to assess the stability of the results. In this meta-analysis, all analyses were performed using R 3.5.3 software. Results Twelve qualified articles including a total of 2,935 patients were identified. HART had a significant beneficial effect on OS rate (HR = 0.80, 95% CI: 0.65–0.98). Compared with CFRT, HART demonstrated a significantly higher LRC rate (HR = 0.82, 95% CI: 0.71–0.96). Conclusion Our meta-analysis showed that HART can significantly improve OS and LRC compared with CFRT in patients with HNC.

Abstract
OBJECTIVE To analyze two cohorts of locally advanced head and neck cancer (LAHNC) patients treated with two schedules of hypofractionated radiotherapy and 5 versus 3 mm clinical target volume-planning target volume (CTV-PTV) margins. METHODS 145 patients were included. The patient cohort was divided into two groups. Group A included 97 patients treated with 69.96/54.45 grays (Gy) to the high-risk and low-risk volumes, respectively, in 33 fractions, with 5 mm margins. Group B included 48 patients treated with 66/54 Gy in 30 fractions using 3 mm margins. Toxicity was recorded according to the Common Toxicity Criteria version 3. Patient outcomes for locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) were determined. RESULTS Median follow-up was 26 months. In terms of toxicity, acute dysphagia worsened significantly (P = 0.003) in group B, whereas acute salivary toxicity tended to significance (P = 0.071). No significant late toxicity differences were recorded. Rates of LRC at 1 and 2 years were 90.1% ± 2.6% and 84.2% ± 3.4%, respectively, with superiority for group A (P = 0.045). The statistical significance remained for the low-dose level (P = 0.007) but not for high dose (P = 0.110). Rates of DFS at 1 and 2 years were 84.9% ± 3.1% and 76.5% ± 3.9%, respectively, whereas rates of OS were 95.9% ± 1.8% and 91.6% ± 2.7%, respectively. No differences were observed between the two groups in terms of DFS (P = 0.270) and OS (P = 0.152). CONCLUSION The use of reduced CTV to PTV margins and dose reduction with hypofractionation schedule can improve the pattern of toxicity in LAHNC patients. This approach resulted in an increased rate of locoregional progression, particularly in low-risk regions. LEVEL OF EVIDENCE 4 Laryngoscope, 130:E163-E170, 2020.

Abstract
Patients who undergo upfront curative intent resection for locally advanced squamous cell carcinomas and who have adverse pathologic features benefit from adjuvant therapy. Concurrent cisplatin based chemoradiation is an established standard of care endorsed by national guidelines. Controversy now exists on the applicability of this strategy to the good risk human papilloma virus (HPV) related oropharynx cancer (OPC) patient. Ongoing clinical studies are exploring therapeutic de-escalation in the postoperative setting for this distinct patient population. The introduction of immune checkpoint inhibitors to the therapeutic armamentarium for recurrent/metastatic head and neck cancer patients has led to clinical investigation of incorporation of PD-1 inhibition in the postoperative setting.

Abstract
Background Adjuvant radiotherapy in advanced head and neck squamous cell cancer (HNSCC) reduces the risk of local-regional failure and most likely increases the survival rate. Patients at high risk for tumor recurrence may benefit from more aggressive altered fractionation schedules in order to reduce the overall time from surgery to completion of radiotherapy. Here, we reviewed the results of six randomized trials addressing the above hypothesis. Methods In the six trials of interest, a total of 988 patients with locally advanced HNSCC were randomly assigned to receive either accelerated or conventionally fractionated adjuvant radiotherapy. Hazard ratios (HR) were extracted from available publications for local-regional control, distant metastasis as well as overall-, cancer specific- and disease-free survival. Meta-analysis of the effect sizes was performed using fixed and random effect models. Acute and late side effects were categorized and summarized for comparison. Results Accelerated radiotherapy did not improve the loco-regional control (n = 988, HR = 0.740, CI = 0.48–1.13, p = 0.162), progression-free survival (HR = 0.89, CI = 0.76–1.04, p = 0.132) or overall survival (HR = 0.88, CI = 0.75–1.04, p = 0.148) significantly. Acute confluent mucositis occurred with significant higher frequency with accelerated radiotherapy. Late side effects did not differ significantly in either group. Conclusion Accelerated radiotherapy does not result in a significant improvement of loco-regional control or overall survival in high-risk patients. Acute but not late radiation toxicity were more frequent with the accelerated RT technique. In clinical practice accelerated postoperative radiation therapy might be a suitable option only for a subset of patients.

Altered fractionation radiotherapy with or without chemotherapy in the treatment of head and neck cancer: a network meta-analysis. Onco Targets Ther 2018; 11:5465-5483.

Abstract
Objectives A Bayesian network meta-analysis (NMA) was conducted in patients with head and neck cancers (HNCs) to estimate the efficacy and safety of treatment with conventional fractionation radiotherapy (CF), conventional fractionation chemoradiotherapy (CF_CRT), hyperfractionated radiotherapy (HF), hyperfractionated chemoradiotherapy (HF_CRT), accelerated fractionation radiotherapy, accelerated fractionation chemoradiotherapy, accelerated hyperfractionated radiotherapy (HART) or accelerated hyperfractionated chemoradiotherapy (HACRT) to identify superior treatments to aid in clinical decisions. Methods PubMed, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for potentially eligible randomized controlled trials up to December 2016. Overall survival (OS), disease-free survival (DFS) and locoregional control (LRC) were considered efficacy outcomes, whereas acute toxicity and late toxicity on skin and mucosa were considered safety outcomes. The surface under the cumulative ranking curve (SUCRA) was calculated to rank each treatment in each index. Results Data from 72 trials with 21,868 participants were included in the analysis. Concerning OS, all treatments were associated with a significant advantage compared to CF alone, with HR effect sizes ranging from 0.64 to 0.83, and HACRT was significantly more effective than all the other treatments. The network comparisons of both HACRT vs HART and HF_CRT vs HF demonstrated a higher OS benefit, with an HR of 0.78 (95% credible interval [CrI]: 0.64–0.95) and 0.78 (95% CrI: 0.61–0.99), respectively. The results of SUCRA indicated that HACRT had the best ranking for OS and LRC, HF_CRT for DFS, HART for acute and late skin toxicity, CF_CRT for acute mucosal toxicity and HF_CRT for late mucosal toxicity. Conclusion The NMA results support the notion that HACRT is the preferable treatment modality for HNCs because it has better rankings in all three efficacy indexes, although it does present a high risk of acute mucosal toxicity.

Predictors of Early Recurrence Prior to Planned Postoperative Radiation Therapy for Oral Cavity Squamous Cell Carcinoma and Outcomes Following Salvage Intensified Radiation Therapy. Int J Radiat Oncol Biol Phys 2018; 103:363-373. [PMID: 30244160 DOI: 10.1016/j.ijrobp.2018.09.013] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2018] [Revised: 09/07/2018] [Accepted: 09/11/2018] [Indexed: 02/07/2023]
Abstract
PURPOSE To determine predictors and outcomes for oral squamous cell carcinoma (OSCC) patients who had early recurrence before commencement of postoperative radiation therapy (PORT). METHODS Retrospective review was performed for patients with OSCC treated with PORT between 2003 and 2015 after curative-intent surgery. Early recurrence was defined as tumor recurrence after surgical resection and before initiating planned PORT. Patients were classified into the following groups: (1) adjuvant PORT group (no early recurrence), (2) salvage PORT group (locoregional early recurrence), and (3) palliative PORT group (locoregional and distant early recurrence). For the whole cohort, multivariable analysis (MVA) was applied to identify predictors of early recurrence. In the salvage group, the post-PORT recurrence-free rate was estimated, and MVA was used to identify predictors of recurrence-free rate, disease-free survival, and overall survival (OS). RESULTS Six hundred and one patients were identified, of whom 513 (85%) were treated with adjuvant PORT. Eighty-eight patients (15%) had early recurrence (28 of 88; 32% were biopsy proven) before PORT (70 in the salvage group and 18 in the palliative group). On MVA, oral tongue subsite, microscopic positive resection margin, pT3-4, and pN2-3 were associated with the development of early recurrence (P < .05 for all). The 3-year OS rates for patients with OSCC treated with adjuvant and salvage PORT were 71% (95% confidence interval [CI], 67%-75%) and 41% (95% CI, 30%-56%), respectively (P < .001; median follow-up was 3.4 and 2.9 years, respectively). After salvage PORT, the 3-year recurrence-free rate was 36% (95% CI, 23%-47%). On MVA, extranodal extension and volume of early recurrent gross disease were associated with poor recurrence-free rate, disease-free survival, and OS (P < .05 for all). CONCLUSION Early recurrences are not uncommon in patients with high-risk features, Further study is required to improve prediction and outcomes of this very high-risk group.

Abstract
BACKGROUND The Meta-Analysis of Radiotherapy in squamous cell Carcinomas of Head and neck (MARCH) showed that altered fractionation radiotherapy is associated with improved overall and progression-free survival compared with conventional radiotherapy, with hyperfractionated radiotherapy showing the greatest benefit. This update aims to confirm and explain the superiority of hyperfractionated radiotherapy over other altered fractionation radiotherapy regimens and to assess the benefit of altered fractionation within the context of concomitant chemotherapy with the inclusion of new trials. METHODS For this updated meta-analysis, we searched bibliography databases, trials registries, and meeting proceedings for published or unpublished randomised trials done between Jan 1, 2009, and July 15, 2015, comparing primary or postoperative conventional fractionation radiotherapy versus altered fractionation radiotherapy (comparison 1) or conventional fractionation radiotherapy plus concomitant chemotherapy versus altered fractionation radiotherapy alone (comparison 2). Eligible trials had to start randomisation on or after Jan 1, 1970, and completed accrual before Dec 31, 2010; had to have been randomised in a way that precluded prior knowledge of treatment assignment; and had to include patients with non-metastatic squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx undergoing first-line curative treatment. Trials including a non-conventional radiotherapy control group, investigating hypofractionated radiotherapy, or including mostly nasopharyngeal carcinomas were excluded. Trials were grouped in three types of altered fractionation: hyperfractionated, moderately accelerated, and very accelerated. Individual patient data were collected and combined with a fixed-effects model based on the intention-to-treat principle. The primary endpoint was overall survival. FINDINGS Comparison 1 (conventional fractionation radiotherapy vs altered fractionation radiotherapy) included 33 trials and 11 423 patients. Altered fractionation radiotherapy was associated with a significant benefit on overall survival (hazard ratio [HR] 0·94, 95% CI 0·90-0·98; p=0·0033), with an absolute difference at 5 years of 3·1% (95% CI 1·3-4·9) and at 10 years of 1·2% (-0·8 to 3·2). We found a significant interaction (p=0·051) between type of fractionation and treatment effect, the overall survival benefit being restricted to the hyperfractionated group (HR 0·83, 0·74-0·92), with absolute differences at 5 years of 8·1% (3·4 to 12·8) and at 10 years of 3·9% (-0·6 to 8·4). Comparison 2 (conventional fractionation radiotherapy plus concomitant chemotherapy versus altered fractionation radiotherapy alone) included five trials and 986 patients. Overall survival was significantly worse with altered fractionation radiotherapy compared with concomitant chemoradiotherapy (HR 1·22, 1·05-1·42; p=0·0098), with absolute differences at 5 years of -5·8% (-11·9 to 0·3) and at 10 years of -5·1% (-13·0 to 2·8). INTERPRETATION This update confirms, with more patients and a longer follow-up than the first version of MARCH, that hyperfractionated radiotherapy is, along with concomitant chemoradiotherapy, a standard of care for the treatment of locally advanced head and neck squamous cell cancers. The comparison between hyperfractionated radiotherapy and concomitant chemoradiotherapy remains to be specifically tested. FUNDING Institut National du Cancer; and Ligue Nationale Contre le Cancer.

Abstract
PURPOSE To present the long-term and final report of a phase 3 trial designed to assess dose-response relationship for postoperative radiation therapy (PORT) and pathologic risk groups in head and neck cancer. METHODS AND MATERIALS Patients who underwent primary surgery for American Joint Committee on Cancer stage III or IV squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx and who required PORT were eligible. Patients' primary sites and involved necks were independently assigned to higher- or lower-risk categories based on a cumulative point score representing increasing risk of recurrence. The sites in the lower-risk group were randomized to receive 57.6 or 63 Gy and those in the higher-risk group were randomized to receive 63 or 68.4 Gy, all at 1.8 Gy per fraction. RESULTS A total of 264 patients were included. The actuarial 5-year locoregional control rate was 67%. A second primary cancer was documented in 27% of patients. The 5- and 10-year freedom-from-distant metastasis rates were 64% and 60%, respectively, whereas the 5- and 10-year overall survival rates were 32% and 20%, respectively. There was no statistically significant difference in tumor control between different dose levels in both the lower- and higher-risk groups. On multivariate analysis, nonwhite race (P=.0003), positive surgical margins (P=.009), extracapsular extension (ECE, P=.01), and treatment package time (TPT) ≥85 days (P=.002) were independent correlates of worse locoregional control, whereas age ≥57 years (P<.0001), positive surgical margins (P=.01), ECE (P=.026), and TPT ≥85 days (P=.003) were independently associated with worse overall survival. CONCLUSIONS This long-term report of PORT delivered at 1.8 Gy/d to total doses of 57.6 to 68.4 Gy without chemotherapy for head and neck squamous cell carcinoma demonstrated that increasing dose did not significantly improve tumor control. On multivariate analysis, the only significant treatment variable was TPT. The results confirm that positive surgical margins and/or nodal ECE remains the most significant predictive pathologic factors.

Postoperative radiotherapy dose requirement in standard combined-modality practice for head and neck squamous cell carcinoma: Analysis of salient surgical and radiotherapy parameters in 2 cohorts. Head Neck 2017; 39:1788-1796.

Abstract
BACKGROUND This study compared 2 sequential cohorts to identify the postoperative radiotherapy (PORT) dose requirement for head and neck squamous cell carcinoma (HNSCC). METHODS Two distinct PORT dose regimens were prescribed over 11 years; group 1 received 56 Gy or less, and group 2 received 60 Gy or more. The 2D and 3D techniques were used. RESULTS Two sequential cohorts consisted of 478 patients, with mean and median follow-up for group 1 and 2 as: 37.0 versus 28.5 months and 13.8 versus 13.1 months, respectively. Grades 3-4 mucosal toxicities (11.4% vs 28.3%), hospitalization (3.2% vs 17.4%), and nasogastric feeding (11.9% vs 29.7%) were higher in group 2. The 2-year disease-free survival (DFS) was higher with PORT >60 Gy for the following factors: age ≤ 50 years (P = .041); ≥ 4 positive nodes (P = .029); and overall treatment time (OTT) ≥ 100 days (P = .042). CONCLUSION Except for the benefit of doses >60 Gy for limited parameters, a lower PORT dose did not compromise the results and can potentially reduce the morbidities and healthcare costs.

Randomized clinical trial on 7-days-a-week post-operative radiotherapy vs concurrent post-operative radiochemotherapy in locally advanced cancer of the oral cavity/oropharynx: a report on acute normal tissue reactions. Br J Radiol 2016; 89:20150805.

Abstract
OBJECTIVE The purpose of the study was to evaluate acute normal tissue reactions and treatment compliance in a randomized clinical trial on 7-days-a-week post-operative radiotherapy (p-CAIR) vs post-operative concurrent radiochemotherapy (p-RTCT) in locally advanced cancer of the oral cavity/oropharynx. The sample analyzed at present represents approximately 30% of the intended future trial size. METHODS The patients were randomly assigned to receive 63 Gy in 1.8-Gy fractions 7 days a week (n = 44) or 63 Gy in 1.8-Gy fractions 5 days a week with concurrent cisplatin 80-100 mg per square metre of body surface area on Days 1, 22 and 43 of the course of radiotherapy (n = 40). Acute mucosal reactions were scored using the modified Dische system. RESULTS 15 (17.9%) patients, including 5 patients in p-CAIR and 10 patients in p-RTCT, did not comply with the assigned radiation treatment, mostly because of rapid tumour progression or deteriorating general performance. In p-RTCT, 22 (55%) patients received less than the intended three courses of chemotherapy mostly owing to haematological toxicity. The average maximum mucosal severity score was 14.2 in p-CAIR compared with 13.4 in p-RTCT; the difference was not statistically significant (p = 0.31). CONCLUSION The schedules compared (p-CAIR and p-RTCT) did not differ considerably with respect to acute mucosal reactions. Haematological toxicity in p-RTCT was elevated compared with p-CAIR. Both schedules were considered tolerable with respect to acute toxicity, which justifies further recruitment to the trial. ADVANCES IN KNOWLEDGE The results show that early mucosal reactions are comparable in both trial arms but haematological toxicity is more pronounced during radiochemotherapy.

Abstract
PURPOSE To systematically review the outcomes of randomized trials testing radiation therapy (RT) intensification, including both dose escalation and/or the use of altered fractionation, as a strategy to improve disease control for a number of malignancies. METHODS AND MATERIALS We performed a literature search to identify randomized trials testing RT intensification for cancers of the central nervous system, head and neck, breast, lung, esophagus, rectum, and prostate. Findings were described qualitatively. Where adequate data were available, pooled estimates for the effect of RT intensification on local control (LC) or overall survival (OS) were obtained using the inverse variance method. RESULTS In primary central nervous system tumors, esophageal cancer, and rectal cancer, randomized trials have not demonstrated that RT intensification improves clinical outcomes. In breast cancer and prostate cancer, dose escalation has been shown to improve LC or biochemical disease control but not OS. Radiation therapy intensification may improve LC and OS in head and neck and lung cancers, but these benefits have generally been limited to studies that did not incorporate concurrent chemotherapy. CONCLUSIONS In randomized trials, the benefits of RT intensification have largely been restricted to trials in which concurrent chemotherapy was not used. Novel strategies to optimize the incorporation of RT in the multimodality treatment of solid tumors should be explored.

Abstract
Oral mucositis (OM) is among the most undesirable, painful, and expensive toxicities of cytotoxic cancer therapy, and is disheartening for patients and frustrating for caregivers. Accurate assessment of the incidence of OM has been elusive, but accumulating data suggests that reported OM frequency is significantly less than its actual occurrence. It has been suggested that over 90% of head and neck cancer (HNC) patients receiving radiotherapy (RT) with concurrent cisplatin experience severe OM with symptoms of extreme pain, mucosal ulceration and consequent limitations in swallowing and achieving adequate nutritional intake. This panoply of symptoms inevitably impacts a patients' quality of life and their willingness to continue treatment. In spite of all the advances made in understanding the pathophysiology of OM, there is still no prophylactic therapy with proven efficacy. Strategies to limit the extent of OM and to manage its symptomatology include basic oral care, supportive medications, nutritional support and targeting aggressive treatments to high-risk patients. This review focuses on OM recognition, preventive measurements, and symptom-management strategies.

Abstract
Treatment delays in completing radiotherapy (RT) for many neoplasms are a major problem affecting treatment outcome, as increasingly shown in the literature. Overall treatment time (OTT) could be a critical predictor of local tumor control and/or survival. In an attempt to establish a protocol for managing delays during RT, especially for heavily overloaded units, we have extensively reviewed the available literature on head and neck cancer. We confirmed a large deleterious effect of prolonged OTT on both local control and survival of these patients.

Abstract
BACKGROUND Many studies have demonstrated the advantage of postoperative concurrent chemoradiotherapy (CRT) over radiotherapy (RT) alone in locoregional control, but few have examined overall survival with respect to national databases. METHODS The literature was searched for eligible randomized controlled trials. The Surveillance, Epidemiology, and End Results (SEER) Database and National Cancer Data Base (NCDB) were searched for 5-year overall survival data. RESULTS Twenty-eight studies were examined and demonstrated 44% greater locoregional control (relative risk [RR] = 0.56; 95% confidence interval [CI] = 0.46-0.68) and 12% overall survival benefit (RR = 0.88; 95% CI = 0.81-0.98) with postoperative adjuvant CRT compared to adjuvant RT. Overall SEER survival was 45.0% in 1973, rising to 53.2% in 2005. The NCDB documents a similar increase in overall survival from 45.5% in 1994 to 53.4% in 2005. CONCLUSION The literature shows mortality benefit of adjuvant CRT in patients with advanced head and neck cancer, reflected in SEER and NCDB.

Partial glossectomy and floor of mouth (FOM) defect repair with biological dural graft: A case report. Int J Surg Case Rep 2015; 11:78-82.

Abstract
Introduction Oral carcinoma can cause significant defects that would necessitate a challenging reconstructive surgery. These techniques include biological or synthetic dressings, grafts, regional flaps, and free-vascularized flaps. Among these, the dural graft has demonstrated promising results in repairing the skull-base defects. Our aim is to report a new, innovative technique for partial glossectomy and floor of mouth defect repair using a biological dural graft dressing when primary repair was not feasible and the patient did not consent to dermal graft or flap interventions. Presentation of case This article reports the outcomes from a novel intervention of partial glossectomy repair using a biological dural dressing derived from bovine type-I collagen in a 57-year-old female patient with recurrent T1N1M0 squamous cell carcinoma of the left-sided tongue during the 12 month period of follow-up. Discussion The best option for large tongue defects is a free flap, while for a moderate defect is a regional oral flap. The biological graft, as an acellular dermal graft has been well known to facilitate secondary healing in the tongue as an alternative to the split-thickness skin graft. In the current study, the dural dressing in tongue reconstruction was likewise shown to be an effective biological dressing; hence, the collagen membrane is biologically acceptable to the oral mucosa and an excellent wound graft material. However, it is absolutely contraindicated in bovine hypersensitive patients. Conclusion The biological dural graft dressing appears to be an effective method for tongue reconstruction, as it promotes adequate wound healing and it preserves function.

Abstract
BACKGROUND About 10,000 persons are diagnosed as having carcinoma of the oral cavity or the throat in Germany every year. Squamous-cell carcinoma accounts for 95% of cases. METHODS We systematically reviewed the pertinent literature on predefined key questions about these tumors (which were agreed upon by a consensus of the investigators), concerning imaging, the removal of cervical lymph nodes, and resection of the primary tumor. RESULTS 246 clinical trials were selected for review on the basis of 3014 abstracts. There was only one randomized, controlled trial (evidence level 1-); the remaining trials reached evidence levels 2++ to 3. Patients with mucosal changes of an unclear nature persisting for more than two weeks should be examined by a specialist without delay. The diagnosis is made by computed tomography or magnetic resonance imaging along with biopsy and a standardized histopathological examination. Occult metastases are present in 20% to 40% of cases. Advanced disease (stages T3 and T4) should be treated by surgery followed by radiotherapy, with or without chemotherapy. 20% of the patients overall go on to have a recurrence, usually within 2 to 3 years of the initial treatment. The 5-year survival rate is somewhat above 50%. Depending on the radicality of surgery and radiotherapy, there may be functional deficits, osteoradionecrosis, and xerostomia. The rate of loss of implants in irradiated bone is about 10% in 3 years. CONCLUSION The interdisciplinary planning and implementation of treatment, based on the patient's individual constellation of findings and personal wishes, are prerequisites for therapeutic success. Reconstructive measures, particularly microsurgical ones, have proven their usefulness and are an established component of surgical treatment.

Abstract
Head and neck cancer may be easily controlled at early stages, but resectable locally advanced disease often relapses at T and N sites. Therefore, adequate adjuvant treatment is of crucial importance for improving local control and/or survival. Unfortunately, little data are available on the adjuvant setting. Adjuvant radiotherapy is regarded as a standard approach for patients with locally advanced radically resected head and neck cancer, while postoperative chemotherapy alone cannot be considered outside of clinical trials. However, chemoradiotherapy is widely considered superior to radiotherapy in patients at a high risk of relapse and may be considered the standard treatment in this population. In this respect, in the last few decades, there has been a growing interest due to the emerging data on both tumor biology and clinical trials. Several pathological and molecular factors, affecting behavior and head and neck cancer prognosis, could allow for a better selection of postoperative treatment. More recently, new prognostic and predictive factors were identified, including biomolecular aspects, human papillomavirus infection and lifestyle. The integration of these new factors deserves dedicated clinical studies, but the available knowledge already allows some deductive hypotheses. We performed a review of the literature to analyze the role of therapy in the postoperative setting and to discuss both the possibility of a different approach to each class of risk and the unsolved question for which randomized trials are warranted.

Abstract
BACKGROUND Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). OBJECTIVES To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment. SEARCH STRATEGY Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 16 February 2011), CENTRAL (The Cochrane Library 2011, Issue 1), MEDLINE via OVID (1950 to 16 February 2011), EMBASE via OVID (1980 to 16 February 2011), CINAHL via EBSCO (1980 to 16 February 2011), CANCERLIT via PubMed (1950 to 16 February 2011), OpenSIGLE (1980 to 2005) and LILACS via the Virtual Health Library (1980 to 16 February 2011) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. SELECTION CRITERIA Randomised controlled trials of interventions to prevent oral mucositis in patients receiving treatment for cancer. DATA COLLECTION AND ANALYSIS Information regarding methods, participants, interventions, outcome measures, results and risk of bias were independently extracted, in duplicate, by two review authors. Authors were contacted for further details where these were unclear. The Cochrane Collaboration statistical guidelines were followed and risk ratios calculated using random-effects models. MAIN RESULTS A total of 131 studies with 10,514 randomised participants are now included. Overall only 8% of these studies were assessed as being at low risk of bias. Ten interventions, where there was more than one trial in the meta-analysis, showed some statistically significant evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis, compared to either a placebo or no treatment. These ten interventions were: aloe vera, amifostine, cryotherapy, granulocyte-colony stimulating factor (G-CSF), intravenous glutamine, honey, keratinocyte growth factor, laser, polymixin/tobramycin/amphotericin (PTA) antibiotic pastille/paste and sucralfate. AUTHORS' CONCLUSIONS Ten interventions were found to have some benefit with regard to preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for further well designed, and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

Abstract
AIM The aim of study was test efficacy of accelerated postoperative radiotherapy--concomitant boost in patients with advanced larynx cancer. METHODS AND MATERIALS The prospective study included 112 patients with advanced larynx cancer after radical surgical treatment. Patients had postoperative radiation therapy, conventional (C) or accelerated (CB). RESULTS The 3-year overall survival in CB was 59%, in C--58% (p = 0.2), 3-year locoregional control in CB--83%, in C--75% (p = 0.01), the 3-year disease free survival was in CB--72%, C--66% (p = 0.1). CONCLUSION Concomitant boost postoperative radiation therapy did not improve overall survival, loco-regional control, disease free survival. Patients with close surgical margins, longer interval between surgery and radiation, high level of hemoglobin, T4 had benefit from accelerated radiotherapy.

Abstract
BACKGROUND Several trials have studied the role of altered fractionation radiotherapy in head and neck squamous cell carcinoma, but the effect of such treatment on survival is not clear. OBJECTIVES The aim of this individual patient data (IPD) meta-analysis was to assess whether this type of radiotherapy could improve survival. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; CENTRAL (2010, Issue 3); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ISRCTN and additional sources for published and unpublished trials. The date of the most recent search was 8 August 2010. SELECTION CRITERIA We identified randomised trials comparing conventional radiotherapy with hyperfractionated or accelerated radiotherapy, or both, in patients with non-metastatic head and neck squamous cell carcinomas and grouped trials into three pre-specified treatment categories: hyperfractionated, accelerated and accelerated with total dose reduction. Trials were eligible if they began recruitment after 1969 and ended before 1998. DATA COLLECTION AND ANALYSIS We obtained updated individual patient data. Overall survival was the main outcome measure. The secondary outcome measures were local or regional control rates (or both), distant control rates and cause-specific mortality. MAIN RESULTS We included 15 trials with 6515 patients. The median follow up was six years. Tumour sites were mostly oropharynx and larynx; 5221 (74%) patients had stage III-IV disease (UICC 2002). There was a significant survival benefit with altered fractionation radiotherapy, corresponding to an absolute benefit of 3.4% at five years (hazard ratio (HR) 0.92, 95% CI 0.86 to 0.97; P = 0.003). The benefit was significantly higher with hyperfractionated radiotherapy (8% at five years) than with accelerated radiotherapy (2% with accelerated fractionation without total dose reduction and 1.7% with total dose reduction at five years, P = 0.02). There was a benefit in locoregional control in favour of altered fractionation versus conventional radiotherapy (6.4% at five years; P < 0.0001), which was particularly efficient in reducing local failure, whereas the benefit on nodal control was less pronounced. The benefit was significantly higher in the youngest patients (under 50 year old) (HR 0.78, 95% CI 0.65 to 0.94), 0.95 (95% CI 0.83 to 1.09) for 51 to 60 year olds, 0.92 (95% CI 0.81 to 1.06) for 61 to 70 year olds, and 1.08 (95% CI 0.89 to 1.30) for those over 70 years old; test for trends P = 0.007). AUTHORS' CONCLUSIONS Altered fractionation radiotherapy improves survival in patients with head and neck squamous cell carcinoma. Comparison of the different types of altered radiotherapy suggests that hyperfractionation provides the greatest benefit. An update of this IPD meta-analysis (MARCH 2), which will increase the power of this analysis and allow for other comparisons, is currently in progress.

Abstract
BACKGROUND The management of advanced oral cavity and oropharyngeal cancers is problematic and has traditionally relied on surgery and radiotherapy, both of which are associated with substantial adverse effects. Radiotherapy has been in use since the 1950s and has traditionally been given as single daily doses. This method of dividing up the total dose, or fractionation, has been modified over the years and a variety of approaches have been developed with the aim of improving survival whilst maintaining acceptable toxicity. OBJECTIVES To determine which radiotherapy regimens for oral cavity and oropharyngeal cancers result in increased overall survival, disease free survival, progression free survival and locoregional control. SEARCH STRATEGY The following electronic databases were searched: the Cochrane Oral Health Group's Trials Register (to 28 July 2010), CENTRAL (The Cochrane Library 2010, Issue 3), MEDLINE via OVID (1950 to 28 July 2010) and EMBASE via OVID (1980 to 28 July 2010). There were no restrictions regarding language or date of publication. SELECTION CRITERIA Randomised controlled trials where more than 50% of participants had primary tumours of the oral cavity or oropharynx, and which compared two or more radiotherapy regimens, radiotherapy versus other treatment modality, or the addition of radiotherapy to other treatment modalities. DATA COLLECTION AND ANALYSIS Data extraction and assessment of risk of bias was undertaken independently by two or more authors. Study authors were contacted for additional information as required. Adverse events data were collected from published trials. MAIN RESULTS 30 trials involving 6535 participants were included. Seventeen trials compared some form of altered fractionation (hyperfractionation/accelerated) radiotherapy with conventional radiotherapy; three trials compared different altered fractionation regimens; one trial compared timing of radiotherapy, five trials evaluated neutron therapy and four trials evaluated the addition of pre-operative radiotherapy. Pooling trials of any altered fractionation radiotherapy compared to a conventional schedule showed a statistically significant reduction in total mortality (hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.76 to 0.98). In addition, a statistically significant difference in favour of the altered fractionation was shown for the outcome of locoregional control (HR 0.79, 95% CI 0.70 to 0.89). No statistically significant difference was shown for disease free survival.No statistically significant difference was shown for any other comparison. AUTHORS' CONCLUSIONS Altered fractionation radiotherapy is associated with an improvement in overall survival and locoregional control in patients with oral cavity and oropharyngeal cancers. More accurate methods of reporting adverse events are needed in order to truly assess the clinical performance of different radiotherapy regimens.

Abstract
BACKGROUND Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). OBJECTIVES To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment. SEARCH STRATEGY Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 1 June 2010), CENTRAL (The Cochrane Library 2010, Issue 2), MEDLINE via OVID (1950 to 1 June 2010), EMBASE via OVID (1980 to 1 June 2010), CINAHL via EBSCO (1980 to 1 June 2010), CANCERLIT via PubMed (1950 to 1 June 2010), OpenSIGLE (1980 to 2005) and LILACS via the Virtual Health Library (1980 to 1 June 2010) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. SELECTION CRITERIA Randomised controlled trials of interventions to prevent oral mucositis in patients receiving treatment for cancer. DATA COLLECTION AND ANALYSIS Information regarding methods, participants, interventions, outcome measures, results and risk of bias were independently extracted, in duplicate, by two review authors. Authors were contacted for further details where these were unclear. The Cochrane Collaboration statistical guidelines were followed and risk ratios calculated using random-effects models. MAIN RESULTS A total of 131 studies with 10,514 randomised participants are now included. Nine interventions, where there was more than one trial in the meta-analysis, showed some statistically significant evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis, compared to either a placebo or no treatment. These nine interventions were: allopurinol, aloe vera, amifostine, cryotherapy, glutamine (intravenous), honey, keratinocyte growth factor, laser, and polymixin/tobramycin/amphotericin (PTA) antibiotic pastille/paste. AUTHORS' CONCLUSIONS Nine interventions were found to have some benefit with regard to preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for further well designed, and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

Abstract
This review discusses the role of adjuvant treatment after curative surgery for patients with head and neck squamous cell carcinoma (HNSCC). In general, patients with unfavourable prognostic factors have a high-risk of loco-regional recurrence and subsequent worse survival after surgery alone and are therefore considered proper candidates for adjuvant treatment by either postoperative radiotherapy alone or postoperative chemoradiation. Selection of the most optimal adjuvant treatment strategy should be based on the most important prognostic factors. In this review, the different treatment strategies will be discussed in general. More specifically, we will discuss the role of the interval between surgery and radiotherapy, the overall treatment time of radiation, the selection of target volumes for radiation and the value of adding concomitant chemotherapy to postoperative radiation.

Abstract
Abstract
Though early stage head and neck cancers can be cured either by surgery or radiation, patients with locally advanced disease continues to pose a therapeutic challenge. Locoregional failure is the major cause of death in head and neck cancers. As the outcome of locally advanced head and neck cancer is less than promising, a combined modality approach is generally undertaken in this group of patients. The combination of surgery, radiation and more recently, chemotherapy and targeted therapy can improve outcomes in locally advanced head and neck cancer patients. This overview discusses the rationale and role of postoperative radiotherapy (PORT) in advanced head and neck cancers, the radiotherapy technique in brief and methods of enhancing the efficacy of postoperative RT by altering the fractionation schedules and adding chemotherapy and targeted therapy.

Predicting the effect of accelerated fractionation in postoperative radiotherapy for head and neck cancer based on molecular marker profiles: data from a randomized clinical trial. Int J Radiat Oncol Biol Phys 2009; 77:438-46. [PMID: 19733016 DOI: 10.1016/j.ijrobp.2009.05.021] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2008] [Revised: 04/18/2009] [Accepted: 05/09/2009] [Indexed: 11/28/2022]
Abstract
PURPOSE To determine the prognostic and predictive values of molecular marker expression profiles based on data from a randomized clinical trial of postoperative conventional fractionation (p-CF) therapy versus 7-day-per-week postoperative continuous accelerated irradiation (p-CAIR) therapy for squamous cell cancer of the head and neck. METHODS AND MATERIALS Tumor samples from 148 patients (72 p-CF and 76 p-CAIR patients) were available for molecular studies. Immunohistochemistry was used to assess levels of EGFR, nm23, Ki-67, p-53, and cyclin D1 expression. To evaluate the effect of fractionation relative to the expression profiles, data for locoregional tumor control (LRC) were analyzed using the Cox proportional hazard regression model. Survival curves were compared using the Cox f test. RESULTS Patients who had tumors with low Ki-67, low p-53, and high EGFR expression levels and oral cavity/oropharyngeal primary cancer sites tended to benefit from p-CAIR. A joint score for the gain in LRC from p-CAIR based of these features was used to separate the patients into two groups: those who benefited significantly from p-CAIR with respect to LRC (n = 49 patients; 5-year LRC of 28% vs. 68%; p = 0.01) and those who did not benefit from p-CAIR (n = 99 patients; 5-year LRC of 72% vs. 66%; p = 0.38). The nm23 expression level appeared useful as a prognostic factor but not as a predictor of fractionation effect. CONCLUSIONS These results support the studies that demonstrate the potential of molecular profiles to predict the benefit from accelerated radiotherapy. The molecular profile that favored accelerated treatment (low Ki-67, low p-53, and high EGFR expression) was in a good accordance with results provided by other investigators. Combining individual predictors in a joint score may improve their predictive potential.

Abstract
There is often a considerable delay from initial tumour diagnosis to the start of radiotherapy treatment. This paper extends the calculations of a previous paper on the effects of delays before the initiation of radiotherapy treatment to include results from a variety of practical fractionation regimes for three different types of tumour: squamous cell carcinoma (head and neck), breast and prostate. The linear quadratic model of radiation effect, logarithmic tumour growth (coupled with delay times where relevant) and the Poisson model for tumour control probability (TCP) are used to calculate the change in TCP for delays between diagnosis and treatment. Within the limitations of radiobiological modelling, these data can be used to tentatively assess the interactions between delays, dose fractionation and TCP. The results show that delays in the start of radiotherapy treatment do have an adverse effect on tumour control for fast-growing tumours. For example, calculations predict a reduction in local tumour control of up to 1.5% per week's delay for head and neck cancers treated following surgery. In addition, there may be a variety of fractionation regimes that will yield very similar clinical results for each tumour type. It is shown theoretically that, for the tumour types considered here, it is possible to increase the dose per fraction and decrease the number of fractions while maintaining or increasing TCP relative to standard 2 Gy fractionation regimes, although there may be some advantage to using hyperfractionated regimes for head and neck cancers in order to reduce normal tissue effects.

Abstract
PURPOSE To evaluate the normal tissue reactions and loco-regional control rates (LRC) in patients treated with 7-days-a-week postoperative continuous irradiation (p-CAIR) compared to conventionally fractionated 5-days-a-week postoperative radiotherapy (CF). MATERIALS/METHODS Between 2001 and 2004, 279 patients with high-risk squamous cell cancer of the larynx (158 pts.) or cancer of the oral cavity/oropharynx (121 pts.) were enrolled. They were stratified according to the primary cancer site (larynx vs. others) and the treating center and randomized to receive 63 Gy in fractions of 1.8 Gy given 5-days-a-week (140 pts: CF) or 7-days-a-week (139 pts: p-CAIR). RESULTS The acute and late toxicity was considered acceptable, although the proportion of patients with confluent mucositis was higher in p-CAIR compared to CF (60.0 vs. 33.3%). The actuarial 3-year LRC were 64 vs. 70% for CF and p-CAIR, respectively, p=0.32. A statistically significant improvement in 3-year LRC in p-CAIR arm appeared in a subset of the patients with cancer of the oropharynx/oral cavity (74% p-CAIR vs. 53% CF, p=0.02). By contrast, there was no improvement in LRC in a subset of the patients with cancer of the larynx (p=0.46). CONCLUSION An improvement in LRC attributable to acceleration of postoperative radiotherapy appeared restricted to the patients with cancer of the oropharynx/oral cavity. In patients with cancer of the larynx acceleration of postoperative radiotherapy did not have any beneficial effect.

Abstract
Cell kinetic concepts have pervaded radiation therapy since the early part of the 20th century and have been instrumental in the development of modern radiotherapy. In this review, the fundamental radiobiological concepts that have been developed based on cell kinetic knowledge will be revisited and discussed in the context of contemporary radiation therapy. This will include how the proliferation characteristics, variation in sensitivity during the cell cycle and the extent of radiation-induced cell cycle delay translate into a variable time for the expression of damage, how cell kinetics interacts with hypoxia and how the response to fractionated radiation schedules is influenced by cell kinetics in terms of repair, redistribution, reoxygenation and repopulation. The promise of combining radiation with new biologically targeted agents and the potential of non-invasive positron emission tomography imaging of proliferation are areas where cell kinetics will continue to influence radiotherapy practice.

Abstract
AIM: Tumor response and normal tissue toxicity of seven-day-per-week continuous accelerated irradiation (CAIR) for patients with esophageal carcinoma were evaluated and compared to conventional irradiation (CR).
METHODS: Sixty patients with squamous cell carcinoma of the esophagus were randomized into two groups: the CAIR group (30 patients) and the CR group (30 patients). Patients in the CAIR group received radiotherapy (RT) with 2 Gy/fraction per day at 7 d/wk with a total dose of 50-70 Gy (average dose 64.2 Gy). The overall time of irradiation was 3.6-5.0 wk (average 4.6 wk). RT in the CR group was 2 Gy/fraction per day at 5 d/wk with a total dose of 40-70 Gy (average dose 61.7 Gy). The overall time of irradiation was 4.0-7.0 wk (average 6.4 wk).
RESULTS: The data showed that the immediate tumor response to RT was better in the CAIR group than in the CR group. Efficiency rates (CR plus PR) were 82.8% (24/29) and 58.6% (17/29), respectively (P = 0.047). In both groups the incidences of esophagitis and tracheitis were insignificant (P = 0.376, 0.959), and no patient received toxicity that could not be tolerated.
CONCLUSION: CAIR shortens overall treatment time and is well tolerated by patients. It may be superior to CR in enhancing the local response of tumor, but its remote effect for esophageal carcinoma awaits further follow-up.

Abstract
Pain from radiation therapy (RT)-induced mucositis is a significant clinical problem for patients with head and neck cancer (HNC). The purpose of this study was to determine the pattern, severity, and time course of RT-induced mucositis pain; self-care behaviors (SCBs) used to manage mucositis pain; and the effectiveness of these behaviors in relieving such pain. Forty-nine patients with HNC were assessed using the MacDibbs Mouth Assessment Tool to determine the severity of RT-induced mucositis pain over their course of RT and at a one-month follow-up visit. All patients developed pain due to RT-induced mucositis. A Self-Care Diary was used weekly by patients to record SCBs and their effectiveness. The most effective SCBs for RT-induced mucositis pain were mouth rinsing and using oral analgesics. However, more severe pain with swallowing was not managed well throughout the study. Future studies need to test more effective strategies to manage RT-induced mucositis pain.

Abstract
PURPOSE The aim of this study was to investigate the prognostic significance of epidermal growth factor (EGFr) expression in oral cavity squamous cell carcinoma (OCSCC) treated with curative surgery and postoperative radiotherapy. METHODS AND MATERIALS This retrospective study included 165 OCSCC patients. The expression of EGFr was assessed on paraffin-embedded tissue of the primary tumor by immunohistochemistry using a monoclonal antibody directed against EGFr. Intensity of the EGFr expression was scored by two authors blinded for the clinical outcome. RESULTS In the univariate analysis, locoregional control at 3 years (LRC) in the EGFr-negative cases was 69% compared with 77% in the EGFr-positive cases (p = 0.22). In the multivariate analysis for local control, a significant interaction was found between EGFr and overall treatment time of radiation (OTT). After stratification for EGFr expression, the OTT was of no importance in the EGFr-negative cases, whereas a significant difference in LRC was found in the EGFr-positive cases, in which the LRC after 3 years was 69% and 94% in case of an OTT of 0-42 days and >42 days, respectively (p = 0.009; hazard ratio = 3.42; 95% confidence interval, 1.28-8.96). No significant association was found between EGFr expression and overall survival. CONCLUSIONS In the present study, no association was found between EGFr expression and outcome regarding locoregional control and overall survival. However, the results of the present study suggest that patients with squamous cell carcinoma of the oral cavity with high EGFr expression benefit more from a reduction of the overall treatment time of postoperative radiation than those with low EGFr expression.

Abstract
BACKGROUND In this prospective study, the effects of a second course of postoperative radiation therapy on locoregional control, survival, toxicity, and quality of life were investigated in patients who underwent resection of a second primary or locoregional recurrent head and neck tumor in a previously irradiated area. METHODS In total, 39 patients who underwent surgery for second primary tumors (n = 19 patients) or for recurrent locoregional tumors (n = 20 patients) were retreated with postoperative radiotherapy (RE-PORT). Indications for RE-PORT were extranodal spread (49%), positive surgical margins (44%), and/or other risk factors (8%). The target volume for RE-PORT was confined to the high-risk area. No elective radiotherapy was applied in regions that were situated in the formerly high-dose area. A total dose of 46 grays (Gy) was given to elective areas with boosts from 60 Gy to 66 Gy to the high-risk region with conventional fractionation. The results of RE-PORT were compared with the results from patients who were treated in the same period with primary adjuvant radiotherapy (PRI-PORT) at the authors' institution. RESULTS The mean follow-up was 32 months (range, 3-84 mos). The locoregional control rate after 3 years in the RE-PORT group was 74%, and the 3-year overall survival rate was 44%. This did not differ significantly compared with survival rates in the PRI-PORT group. Although a higher rate of late radiation-induced morbidity and more head and neck symptoms were observed in the RE-PORT group compared with the PRI-PORT group, no differences were observed with regard to the more general dimensions of quality of life. CONCLUSIONS RE-PORT after surgery for recurrent locoregional tumors and/or second primary tumors should be considered in patients who have high-risk histopathologic features.

Abstract
BACKGROUND Treatment of cancer is increasingly more effective but is associated with short and long-term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). OBJECTIVES To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment. SEARCH STRATEGY The Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE were searched. Reference lists from relevant articles were scanned and the authors of eligible studies were contacted to identify trials and obtain additional information. Date of most recent searches: April 2004. SELECTION CRITERIA Trials were selected if they met the following criteria: design - random allocation of participants; participants - anyone with cancer receiving chemotherapy or radiotherapy treatment for cancer; interventions - agents prescribed to prevent oral mucositis; outcomes - prevention of mucositis, pain, amount of analgesia, dysphagia, systemic infection, length of hospitalisation, cost and patient quality of life. DATA COLLECTION AND ANALYSIS Information regarding methods, participants, interventions and outcome measures and results were independently extracted, in duplicate, by two review authors. Authors were contacted for details of randomisation and withdrawals and a quality assessment was carried out. The Cochrane Oral Health Group statistical guidelines were followed and risk ratios (RR) calculated using random-effects models. MAIN RESULTS Two hundred and two studies were eligible. One hundred and thirty two were excluded for various reasons, usually as there was no useable information on mucositis. Of the 71 useable studies all had data for mucositis comprising 5217 randomised patients. Interventions evaluated were: acyclovir, allopurinol mouthrinse, aloe vera, amifostine, antibiotic pastille or paste, benzydamine, beta carotene, calcium phosphate, camomile, chlorhexidine, clarithromycin, folinic acid, glutamine, GM-CSF, honey, hydrolytic enzymes, ice chips, iseganan, keratinocyte GF, misonidazole, oral care, pentoxifylline, povidone, prednisone, propantheline, prostaglandin, sucralfate, traumeel and zinc sulphate. Of the 29 interventions included in trials, 10 showed some evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis. Interventions where there was more than one trial in the meta-analysis finding a significant difference when compared with a placebo or no treatment were: amifostine which provided minimal benefit in preventing moderate and severe mucositis RR = 0.84 (95% confidence interval (CI) 0.75 to 0.95) and 0.60 (95% CI 0.37 to 0.97), antibiotic paste or pastille demonstrated a moderate benefit in preventing mucositis RR = 0.87 (95% CI 0.79 to 0.97), hydrolytic enzymes reduced moderate and severe mucositis with RRs = 0.52 (95% CI 0.36 to 0.74) and 0.17 (95% CI 0.06 to 0.52), and ice chips prevented mucositis at all levels RR = 0.63 (95% CI 0.44 to 0.91), 0.43 (95% CI 0.23 to 0.81), 0.27 (95% CI 0.11 to 0.68). Other interventions showing some benefit with only one study were: benzydamine, calcium phosphate, honey, oral care protocols, povidone and zinc sulphate. The number needed to treat (NNT) to prevent one patient experiencing moderate or severe mucositis over a baseline incidence of 60% for amifostine is 10 (95% CI 7 to 33), antibiotic paste or pastille 13 (95% CI 8 to 56), hydrolytic enzyme 4 (95% CI 3 to 6) and ice chips 5 (95% CI 3 to 19). When the baseline incidence is 40%/90% the NNTs for amifostine are 16/7, for antibiotic paste or pastille 19/7, for hydrolytic enzyme 5/3 and for ice chips 7/3. The general reporting of RCTs was poor. However, the assessments of the quality of the randomisation improved when the authors provided additional information. AUTHORS' CONCLUSIONS Several of the interventions were found to have some benefit at preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for well designed and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.
