Treatment outcomes and survival following definitive (chemo)radiotherapy in HPV-positive oropharynx cancer: Large-scale comparison of DAHANCA vs PMH cohorts. Int J Cancer 2021; 150:1329-1340. [PMID: 34792199 DOI: 10.1002/ijc.33876] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Revised: 10/17/2021] [Accepted: 11/02/2021] [Indexed: 11/05/2022]
Abstract
We compare outcomes in two large-scale contemporaneously treated HPV-positive (HPV+) oropharynx cancer (OPC) cohorts treated with definitive radiotherapy/chemoradiotherapy (RT/CRT). p16-confirmed HPV+ OPC treated between 2007 and 2015 at PMH and DAHANCA were identified. Locoregional failure (LRF), distant metastasis (DM), and overall survival (OS) were compared. Multivariable analysis (MVA) calculated adjusted-hazard-ratio (aHR) with 95% confidence interval (95% CI), adjusting for cohort, age, gender, performance status, smoking pack-years, T-category and N-category and chemotherapy. Compared to PMH (n = 701), DAHANCA (n = 1174) contained lower TNM-8T-categories (T1-T2: 77% vs 56%), N-categories (N0-N1: 77% vs 67%) and stages (stage I: 63% vs 44% (all P < .001). PMH used standard-fractionation CRT in 69% (481) while 31% (220) received hypofractionated or moderately accelerated RT-alone. All DAHANCA patients were treated with moderately accelerated RT; 96% (1129) received nimorazole (NIM) and 73% (856) concurrent weekly cisplatin. DAHANCA had shorter overall-treatment-time (P < .001), lower gross tumor (66-68 vs 70 Gy) and elective neck (50 vs 56 Gy) doses. Median follow-up was 4.8 years. DAHANCA had higher 5-year LRF (13% vs 7%, aHR = 0.47 [0.34-0.67]), comparable DM (7% vs 12%, aHR = 1.32 [0.95-1.82]), but better OS (85% vs 80%, aHR = 1.30 [1.01-1.68]). CRT patients had a lower risk of LRF (aHR 0.56 [0.39-0.82]), DM (aHR 0.70 [0.50-1.00]) and death (aHR 0.39 [0.29-0.52]) vs RT-alone. We observed exemplary outcomes for two large-scale trans-Atlantic HPV+ OPC cohorts treated in a similar manner. Concurrent chemotherapy was a strong, independent prognostic factor for all endpoints. Our findings underscore the need for a very careful approach to de-intensification of treatment for this disease.

Abstract
ABSTRACT Triple-negative breast cancer, compared with other molecular subtypes, poses particular challenges for optimizing the timing and the extent of locoregional treatments. In the past, the combination of increased rates of both locoregional and distant recurrences led to a preference of radical surgery and extensive radiation therapy; however, since the introduction of more effective chemotherapy, a sharp de-escalation in the extent of locoregional treatments followed. Current evidence confirms that less aggressive surgery in combination with tailored radiation therapy offers improved oncological outcomes combined with better quality of life. However, further research is required to optimize locoregional treatments, considering the significant heterogeneity in biological behavior and tumor response to systemic treatments.

Abstract
Background The objective of this study was to identify a subgroup of patients with head and neck squamous cell carcinoma (HNSCC) who might be suitable for hypofractionated radiotherapy (RT‐hypo) during the COVID‐19 pandemic. Methods HNSCC cases (oropharynx/larynx/hypopharynx) treated with definitive RT‐hypo (60 Gy in 25 fractions over 5 weeks), moderately accelerated radiotherapy (RT‐acc) alone (70 Gy in 35 fractions over 6 weeks), or concurrent chemoradiotherapy (CCRT) during 2005‐2017 were included. Locoregional control (LRC) and distant control (DC) after RT‐hypo, RT‐acc, and CCRT were compared for various subgroups. Results The study identified 994 human papillomavirus–positive (HPV+) oropharyngeal squamous cell carcinoma cases (with 61, 254, and 679 receiving RT‐hypo, RT‐acc, and CCRT, respectively) and 1045 HPV– HNSCC cases (with 263, 451, and 331 receiving RT‐hypo, RT‐acc, and CCRT, respectively). The CCRT cohort had higher T/N categories, whereas the radiotherapy‐alone patients were older. The median follow‐up was 4.6 years. RT‐hypo, RT‐acc, and CCRT produced comparable 3‐year LRC and DC for HPV+ T1‐2N0‐N2a disease (seventh edition of the TNM system [TNM‐7]; LRC, 94%, 100%, and 94%; P = .769; DC, 94%, 100%, and 94%; P = .272), T1‐T2N2b disease (LRC, 90%, 94%, and 97%; P = .445; DC, 100%, 96%, and 95%; P = .697), and T1‐2N2c/T3N0‐N2c disease (LRC, 89%, 93%, and 95%; P = .494; DC, 89%, 90%, and 87%; P = .838). Although LRC was also similar for T4/N3 disease (78%, 84%, and 88%; P = .677), DC was significantly lower with RT‐hypo or RT‐acc versus CCRT (67%, 65%, and 87%; P = .005). For HPV– HNSCC, 3‐year LRC and DC were similar with RT‐hypo, RT‐acc, and CCRT in stages I and II (LRC, 85%, 89%, and 100%; P = .320; DC, 99%, 98%, and 100%; P = .446); however, RT‐hypo and RT‐acc had significantly lower LRC in stage III (76%, 69%, and 91%; P = .006), whereas DC rates were similar (92%, 85%, and 90%; P = .410). Lower LRC in stage III predominated in patients with laryngeal squamous cell carcinoma receiving RT‐acc (62%) but not RT‐hypo (80%) or CCRT (92%; RT‐hypo vs CCRT: P = .270; RT‐acc vs CCRT: P = .004). CCRT had numerically higher LRC in comparison with RT‐hypo or RT‐acc in stage IV (73%, 65%, and 66%; P = .336). Conclusions It is proposed that RT‐hypo be considered in place of CCRT for HPV+ T1‐T3N0‐N2c (TNM‐7) HNSCCs, HPV– T1‐T2N0 HNSCCs, and select stage III HNSCCs during the COVID‐19 outbreak. Hypo‐fractionated radiotherapy has disease control comparable to that of chemoradiotherapy in select head and neck cancers, and it is a potential alternative for this subgroup during the COVID‐19 pandemic.

Durable therapeutic gain despite competing mortality in long-term follow-up of a randomized hyperfractionated radiotherapy trial for locally advanced head and neck cancer. Clin Transl Radiat Oncol 2020; 21:69-76. [PMID: 32055717 PMCID: PMC7005479 DOI: 10.1016/j.ctro.2020.01.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2019] [Revised: 01/14/2020] [Accepted: 01/22/2020] [Indexed: 01/06/2023] Open
Abstract
Purpose/objectives To examine the therapeutic ratio and mortality profile over time in a radiotherapy randomized trial in stage III-IV larynx/pharynx cancer with long-term follow-up. Materials/methods From 1988 to 1995, 331 cases were randomized to either hyperfractionated (HF) (58 Gy/40 fractions, twice daily) or conventional (CF) (51 Gy/20 fractions, once daily) radiotherapy. Overall survival (OS), locoregional (LRC), distant control (DC), ≥Grade 3 late toxicity (LT), and relative mortality risk profile over time were compared between both arms. Results Median follow-up was 13.6 years. HF had a 10% improved OS at 5-years (40% vs 30%, p = 0.04), but the benefit diminished to 3% at 10-years (21% vs 18%). A trend towards higher LRC with HF remained (5-year: 49% vs 40%; 10-year: 49% vs 39%, p = 0.05). DC rates were unchanged (5-year: 87% vs 85%; 10-year: 87 vs 84%, p = 0.56). LT rates were similar (HF vs CF: 5-year: 9% vs 12%; 10-year: 11% vs 14%, p = 0.27). Multivariable analysis confirmed that HF reduced mortality risk by 31% [HR 0.69 (0.55-0.88), p < 0.01] and locoregional failure risk by 35% [HR 0.65 (0.48-0.89), p < 0.01]. Index cancer mortality (5-year: 46% vs 51%; 10-year: 49% vs 55%) was lower in the HF arm. Competing mortality (mostly smoking-related) was also numerically lower with HF at 5-years (14% vs 19%) but became similar at 10-years (30% vs 28%). Conclusions This trial confirms that HF with augmented total dose has a durable 10% effect size on LRC with comparable LT. OS benefit is evident at 5-years (10%) but relative mortality risk profile changes in longer follow-up.

Abstract
BACKGROUND Technological advances in radiotherapy have allowed investigations into new methods to spare healthy tissue in those treated for head and neck cancer. This systematic review with meta-analysis demonstrates the effect that radiation has on swallowing. METHODS Selection and analysis of studies examining the effect of radiation to swallowing structures. A fixed effects meta-analysis calculated the pooled proportions for select outcomes of dysphagia, common across many studies. RESULTS The majority of the papers found a correlation between radiation dose to the swallowing structures and dysphagia, however a meta-analysis found the studies carried a significant degree of heterogeneity. The appraisal demonstrates the need for large-scale studies using a randomized design and instrumental dysphagia assessments. CONCLUSIONS Radiation dose to dysphagia and aspiration structures is correlated with incidence of dysphagia and aspiration. The variables in this population contribute to the heterogeneity within and cross studies and future studies should consider controlling for this.

Abstract
BACKGROUND The radiotherapy (rt) volumes in anaplastic (atc) and differentiated thyroid carcinoma (dtc) are controversial. METHODS We retrospectively examined the patterns of failure after postoperative intensity-modulated rt for atc and dtc. Computed tomography images were rigidly registered with the original rt plans. Recurrences were considered in-field if more than 95% of the recurrence volume received 95% of the prescribed dose, out-of-field if less than 20% received 95% of the dose, and marginal otherwise. RESULTS Of 30 dtc patients, 4 developed regional recurrence: 1 being in-field (level iii), and 3 being out-of-field (all level ii). Of 5 atc patients, all 5 recurred at 7 sites: 2 recurrences being local, and 5 being regional [2 marginal (intramuscular to the digastric and sternocleidomastoid), 3 out-of-field (retropharyngeal, soft tissues near the manubrium, and lateral to the sternocleidomastoid)]. CONCLUSIONS In dtc, locoregional recurrence is unusual after rt. Out-of-field dtc recurrences infrequently occurred in level ii. Enlarged treatment volumes to level ii must be balanced against a potentially greater risk of toxicity.

Abstract
Treatment of locally advanced head and neck squamous cell carcinomas requires a multidisciplinary approach to be able to offer patients definitive therapy while aiming to preserve organ function and minimize acute and long-term toxicities. Advances in surgical techniques will be reviewed for both primary sites and the neck and also in the salvage settings. Recent data on concurrent versus sequential chemoradiotherapy in these patients will be reviewed, with emphasis on identification of appropriate patients for sequential chemoradiotherapy. Finally, advances in modern radiotherapy modalities that have resulted in improved dosimetry and quality of life following treatment will be reviewed.

Abstract
BACKGROUND The purpose of this study was to determine the clinical outcomes of T4 laryngeal cancers. METHODS T4 laryngeal cancers treated with curative intent from January 2003 to December 2010 were analyzed. Outcomes were evaluated in both primary radiotherapy (+/- chemotherapy) (RT/CRT) and primary surgery cohorts. RESULTS Among the 65 primary RT/CRT and 42 primary surgery patients included, median follow-up was 4.4 years. There was a trend for improved locoregional control with surgery (74% vs 88%; p = .08). In the RT/CRT group the 3-year laryngectomy-free survival was 67%. The 2-year gastrostomy dependency rate was 23% with RT/CRT versus 6% with primary surgery (p = .07). Overall survival (OS) at 3 years was significantly lower in the RT/CRT versus primary surgery group (41% vs 70%; p < .01). CONCLUSION Laryngeal preservation is achieved in over two thirds of patients with primary RT/CRT. Patients with low volume minimal cartilage involvement T4 disease may be best suited to RT/CRT. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2035-E2040, 2016.

BACKGROUND AND PURPOSE Health related quality of life (HRQoL) was assessed in the randomised, prospective ARTSCAN study comparing conventional radiotherapy (CF) with accelerated radiotherapy (AF) for head and neck cancer. MATERIAL AND METHODS 750 patients with squamous cell carcinoma (of any grade and stage) in the oral cavity, oro-, or hypopharynx or larynx (except T1-2, N0 glottic carcinoma) without distant metastases were randomised to either conventional fractionation (2 Gy/day, 5 days/week in 49 days, total dose 68 Gy) or accelerated fractionation (1.1+2.0 Gy/day, 5 days/week in 35 days, total dose 68 Gy). HRQoL was assessed with EORTC QLQ-C30, QLQ-H&N35 and HADS at baseline, at end of radiotherapy (eRT) and at 3 and 6 months and 1, 2 and 5 years after start of treatment. RESULTS The AF group reported HRQoL was significantly lower at eRT and at 3 months for most symptoms, scales and functions. Few significant differences were noted between the groups at 6 months and 5 years. Scores related to functional oral intake never reached baseline. CONCLUSION In comparison to CF, AF has a stronger adverse effect on HRQoL in the acute phase.

Abstract
BACKGROUND Patients with primary head and neck cancer managed with radiation therapy (RT) +/- chemotherapy may experience significant treatment-related toxicities. We assessed hospitalization as a metric for severe treatment-related toxicities and evaluated patient and treatment factors for possible association. METHODS A retrospective review was performed on 147 patients with head and neck cancer treated with definitive or adjuvant intensity-modulated radiation therapy (IMRT) +/- chemotherapy. Multiple Poisson regression model was used to analyze relationships between patient or treatment factors and number of hospital stays during RT and within 8 weeks after RT. RESULTS Multivariate analysis showed preexisting diabetes or pulmonary disease, primary carcinoma of oral cavity, and prescribed radiation dose (p < .05) were associated with increased number of patient hospital stays during or shortly after RT. CONCLUSION We found that 34.7% of patients experienced a chemoradiation toxicity-related hospitalization during or shortly after treatment. Prior pulmonary disease, diabetes, and increasing prescribed radiation dose were associated with increased hospital stays.

Final long-term results of a phase I/II study of dose-escalated intensity-modulated radiotherapy for locally advanced laryngo-hypopharyngeal cancers. Oral Oncol 2014; 50:1089-97. [PMID: 25200524 DOI: 10.1016/j.oraloncology.2014.07.018] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2014] [Revised: 07/24/2014] [Accepted: 07/25/2014] [Indexed: 11/20/2022]
Abstract
OBJECTIVES We previously described dose-escalated intensity-modulated radiotherapy (IMRT) in squamous cell cancer of the larynx/hypopharynx (SCCL/H) to offer improved locoregional control with a low incidence of toxicity at 2 years. We now present outcome and safety data at 5 years. MATERIALS AND METHODS A sequential cohort Phase I/II trial design was used. Patients with SCCL/H received IMRT at two dose levels (DL): DL1, 63 Gy/28 fractions to planning target volume 1 (PTV1) and 51.8 Gy/28 Fx to PTV2; DL2, 67.2 Gy/28 Fx and 56 Gy/28 Fx to PTV1 and PTV2, respectively. Patients received induction cisplatin/5-fluorouracil and concomitant cisplatin. RESULTS Between 09/2002 and 01/2008, 60 patients (29 DL1, 31 DL2) with stage III (41% DL1, 52% DL2) and stage IV (52% DL1, 48% DL2) disease were recruited. Median (range) follow-up for DL1 was 5.7 (1.0-10.2) years and for DL2 was 6.0 (0.3-8.4) years. Five-year local control rates (95% confidence interval) for DL1 and DL2, respectively, were 68% (50.6-85.4%) and 75% (58.9-91.1%), locoregional progression-free survival rates were 54% (35.6-72.4%) and 62.6% (44.8-80.4%), and overall survival was 61.9% (44.1-79.7) and 67.6 (51.1-84.1%). Five-year laryngeal preservation rates were 66.7% (37.4-87.9%) and 71.4% (44.4-85.8%), respectively. Cumulative toxicities reported were: one patient in DL1 and 2 in DL2 developed benign pharyngeal strictures. No other G3/4 toxicities were reported. CONCLUSIONS Dose-escalated IMRT at DL2 achieves higher 5-year local control, larynx preservation and survival rates with acceptable late toxicity. Recruitment into a Cancer Research UK Phase III study (ART-DECO), with DL2 as the experimental arm, is ongoing.

Abstract
OBJECTIVE Evaluation of the efficacy and toxicity of split-course accelerated hyperfractionated irradiation (CHA-CHA) as a sole treatment for advanced head and neck (H&N) cancer patients. METHODS We enrolled 101 patients (39 in CHA-CHA and 37 in conventional (Conv.) arm completed the treatment). The CHA-CHA arm patients were irradiated twice a day, 7 days a week, using a fraction dose (fd) of 1.6 Gy up to 64 Gy with an 8-day gap in midterm. Patients in the control (Conv.) arm group were irradiated with a fd of 2 Gy, five times a week to a total dose of 72-74 Gy in the overall treatment time of 50-53 days. Quality of life (QOL) and acute mucosal reaction were evaluated during radiotherapy (RT). After RT, we followed the effect of treatment, QOL, performance status and adverse effects of radiation. For statistical analysis mainly a hierarchical multilevel modelling was used. RESULTS QOL was most deteriorated in the CHA-CHA arm; the CHA-CHA scheme also caused a relatively stronger acute injury. There were no significant differences in late adverse effects. In the CHA-CHA arm in 35% and in Conv. arm in 30% of patients, disease was controlled during follow-up. Tumour regression 1 year after the treatment was significantly better in the CHA-CHA arm. However, the overall survival rate analysis did not show significant difference between both arms. CONCLUSION Despite differences in treatment results, we cannot conclude that split-course accelerated hyperfractionated irradiation is superior to conventionally fractionated RT as a sole treatment for advanced H&N cancer patients. ADVANCES IN KNOWLEDGE Obtained results in the context of published data support the statement that altered fractionations alone do not give an advantage for advanced H&N cancer patients.

Abstract
BACKGROUND The purpose of this study was to discuss if the adoption of intensity-modulated radiotherapy (IMRT) for hypopharyngeal squamous cell carcinoma (SCC) has improved the outcome. METHODS We compared 3-dimensional (3D) radiotherapy (RT) and IMRT in all patients with hypopharyngeal SCC treated with curative intent RT or chemoradiation therapy (CRT) from January 1, 2000, to February 28, 2010. Locoregional control, overall survival (OS), distant relapse rate, larynx preservation rate, and enteral feeding tube duration were analyzed. RESULTS Of 181 consecutive patients, 90 received 3D-RT and 91 received IMRT. At 3 years, the IMRT group had higher locoregional control compared with the 3D-RT group (75% vs 58%; p = .003), but similar OS (50% vs 52%; p = .99), distant relapse rate (23% vs 20%; p = .79), and larynx-preservation rate (90% vs 86%; p = .16). The 2-year enteral feeding tube dependency rate was similar in both groups (19% vs 18%; p = .12). CONCLUSION Patients with hypopharyngeal SCC treated with IMRT showed a higher locoregional control compared with 3D-RT. However, distant-relapse rate and OS remain comparable between treatment techniques.

Abstract
PURPOSE To report outcome of HPV-related [HPV(+)] oropharyngeal cancer (OPC) managed predominantly by altered-fractionation radiotherapy-alone (RT-alone). METHODS OPCs treated with RT-alone (n = 207) or chemoradiotherapy (CRT) (n = 151) from 2001 to 2008 were included. Overall survival (OS), local (LC), regional (RC) and distant (DC) control were compared for HPV(+) vs. HPV-unrelated [HPV(-)], by RT-alone vs. CRT, and by smoking pack-years (≤ 10 vs. >10). Multivariate analysis identified predictors. RESULTS HPV(+) (n = 277) had better OS (81% vs. 44%), LC (93% vs. 76%), RC (94% vs. 79%) (all p < 0.01) but similar DC (89% vs. 86%, p = 0.87) vs. HPV(-) (n = 81). HPV(+) stage IV CRT (n = 125) had better OS (89% vs. 70%, p < 0.01), but similar LC (93% vs. 90%, p = 0.41), RC (94% vs. 90%, p = 0.31) and DC (90% vs. 83%, p = 0.22) vs. RT-alone (n = 96). Both HPV(+) RT-alone (n = 37) and CRT (n = 67) stage IV minimal smokers had favorable OS (86% vs. 88%, p = 0.45), LC (95% vs. 92%, p = 0.52), RC (97% vs. 93%, p = 0.22), and DC (92% vs. 86%, p = 0.37). RT-alone and heavy-smoking were independent predictors for lower OS but not CSS in multivariate analysis. CONCLUSIONS Overall, HPV(+) RT-alone stage IV demonstrated lower survival but comparable disease control vs. CRT, but no difference was apparent among minimal smokers.

Abstract
PURPOSE To compare the patterns of care for elderly head-and-neck cancer patients with those of younger patients. METHODS AND MATERIALS A retrospective review was conducted of all new mucosal head-and-neck cancer referrals to radiation oncology between July 1, 2003 and December 31, 2007 at our institution. The clinical characteristics, treatment pattern, tolerance, and outcomes were compared between the elderly (aged ≥75 years) and younger (aged <75 years) cohorts. RESULTS A total of 2,312 patients, including 452 (20%) elderly and 1,860 (80%) younger patients, were studied. The elderly patients were more likely to be women (36% vs. 27%, p <.01) and to have other malignancies (23% vs. 13%, p <.01), Stage I or II disease (38% vs. 32%, p <.01), and N0 status (56% vs. 42%, p <.01). Treatment was less often curative in intent (79% vs. 93%, p <.01). For the 1,487 patients who received definitive radiotherapy (RT), no differences were found between the elderly (n = 238) and younger (n = 1,249) patients in treatment interruption, completion, or treatment-related death. Within the subset of 760 patients who received intensified treatment (concurrent chemoradiotherapy or hyperfractionated accelerated RT), no difference was seen between the elderly (n = 46) and younger (n = 714) patients in treatment interruption, completion, or treatment-related death. After a median follow-up of 2.5 years, the 2-year cause-specific survival rate after definitive RT was 72% (range, 65-78%) for the elderly vs. 86% (range, 84-88%) for the younger patients (p <.01). CONCLUSION Elderly head-and-neck cancer patients exhibited different clinical characteristics and experienced different patterns of care from younger patients. Although age itself was an adverse predictor of cause-specific survival, its effect was modest. Elderly patients selected for definitive RT or intensified RT showed no evidence of impaired treatment tolerance.

Abstract
PURPOSE Rapidly metabolizing tumor cells have elevated levels of nicotinamide phosphoribosyltransferase, an enzyme involved in NAD(+) biosynthesis, which serves as an important substrate for proteins involved in DNA repair. GMX1777, which inhibits nicotinamide phosphoribosyltransferase, was evaluated in two human head and neck cancer models in combination with radiotherapy. EXPERIMENTAL DESIGN Effects of GMX1777-mediated radiosensitization were examined via metabolic and cytotoxicity assays in vitro; mechanism of action, in vivo antitumor efficacy, and radiosensitization were also investigated. RESULTS IC(50) values of GMX1777 for FaDu and C666-1 cells were 10 and 5 nmol/L, respectively, which interacted synergistically with radiotherapy. GMX1777 induced a rapid decline in intracellular NAD(+) followed by ATP reduction associated with significant cytotoxicity. These metabolic changes were slightly increased with the addition of radiotherapy, although poly(ADP-ribose) polymerase activity was significantly reduced when GMX1777 was combined with radiotherapy, thereby accounting for the synergistic cytotoxicity of these two modalities. Systemic GMX1777 administration with local tumor radiotherapy caused complete disappearance of FaDu and C666-1 tumors for 50 and 20 days, respectively. There was also significant reduction in tumor vascularity, particularly for the more sensitive FaDu model. [(18)F]FDG-positron emission tomography/computed tomography images showed reduction in [(18)F]FDG uptake after GMX1777 administration, showing decreased glucose metabolism in vivo. CONCLUSIONS Our data represent the first report showing that GMX1777 plus radiotherapy is an effective therapeutic strategy for head and neck cancer, mediated via pleiotropic effects of inhibition of DNA repair and tumor angiogenesis, while sparing normal tissues. Therefore, GMX1777 combined with radiotherapy definitely warrants clinical evaluation in human head and neck cancer patients.

Abstract
OBJECTIVES To provide an overview of the state of the art in the management of head and neck cancers with radiation therapy (RT) and review issues concerning dose-fractionation, concurrent systemic treatment as well as acute and chronic toxicity. DATA SOURCES Published peer-reviewed research articles, technical documents, and patient management guidelines. CONCLUSION Modern RT techniques can use technical advances to precisely target regions involved by the tumor, while sparing normal structures. This has significant implications for treatment decisions and anticipated treatment toxicities. Our understanding of radiation effects on tumor and normal tissues and their optimal care are continuously evolving. IMPLICATIONS FOR NURSING PRACTICE Nurses need to be aware of the basic principles underlying the technical advances in RT in order to be able to counsel patients during their decision-making and treatment. They also need to stay updated on the pathophysiology and current management of acute and chronic toxicities of radiation treatment in order to provide optimal supportive care.
