Acta Oncol 2023; 62:1375-1383. [PMID: 37682690 DOI: 10.1080/0284186x.2023.2251084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 08/18/2023] [Indexed: 09/10/2023]
Abstract
BACKGROUND Analyses of clinical outcomes following radiotherapy (RT) have advanced our understanding of fundamental radiobiological characteristics in head and neck squamous cell carcinoma (HNSCC). Low fractionation sensitivity appears to be a common feature, as well as susceptibility to changes in overall treatment time (OTT). Large tumors should be harder to cure if a successful RT requires the sterilization of all clonogenic cells. Congruently, primary tumor volume has proven to be an important parameter. However, most findings come from an era when p16-negative HNSCC was the dominant tumor type. HPV-associated, p16-positive, oropharyngeal tumors (OPSCC) are more radiosensitive and have better outcome. The current study aims to investigate the role of primary tumor volume, OTT and estimate α/ β -ratio for p16-positive OPSCC, and to quantify the differences in radiosensitivity depending on p16-status. METHODS A cohort of 523 patients treated with RT was studied using a tumor control probability (TCP)-model that incorporates primary tumor volume (V) raised to an exponent c, OTT and α/ β -estimation. The significance of V was also investigated in Cox-regression models. RESULTS In the p16-positive cohort (n = 433), the volume exponent c was 1.44 (95%CI 1.06-1.91), compared to 0.90 (0.54-1.32) for p16-negative tumors (n = 90). Hazard ratios per tumor volume doubling were 2.37 (1.72-3.28) and 1.83 (1.28-2.62) for p16-positive and p16-negative, respectively. The estimated α/ β -ratio was 9.7 Gy (-2.3-21.6), and a non-significant daily loss of 0.30 Gy (-0.17-0.92) was found. An additional dose of 6.8 Gy (interquartile range 4.8-9.1) may theoretically counteract the more radioresistant behavior of p16-negative tumors. CONCLUSION Primary tumor volume plays a crucial role in predicting local tumor response, particularly in p16-positive OPSCC. The estimated α/β-ratio for p16-positive oropharyngeal tumors aligns with previous HNSCC studies, whereas the impact of prolonged OTT was slightly less than previously reported. The differences in radiosensitivity depending on p16-status were quantified. The findings should be validated in independent cohorts.

A Comparison of the Toxicities in Patients With Locally Advanced Head and Neck Cancers Treated With Concomitant Boost Radiotherapy Versus Conventional Chemoradiation. Cureus 2023; 15:e38362. [PMID: 37266055 PMCID: PMC10230179 DOI: 10.7759/cureus.38362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/27/2023] [Indexed: 06/03/2023] Open
Abstract
PURPOSE To compare the objective and patient-reported toxicities of concomitant boost radiotherapy (CBRT) and concurrent chemoradiation (CRT) in patients with locally advanced head and neck cancers. METHODS AND MATERIAL In this prospective study, 46 patients with histologically proven stage III-IVA head and neck cancer were randomly assigned to receive either concurrent chemoradiation to a dose of 66 Gy in 33 fractions over 6.5 weeks with concurrent cisplatin (40 mg/m2 IV weekly; control arm) or accelerated radiotherapy with concomitant boost radiotherapy (study arm) to a dose of 67.5 Gy in 40 fractions in five weeks. Acute toxicity was evaluated using RTOG toxicity criteria. The assessment was done weekly after initiation of treatment, at the first follow-up (six weeks), and at three months. The four main patient-reported symptoms of pain, hoarseness of voice, dryness of mouth, and loss of taste were also compared between the two groups to assess patient quality of life during treatment. RESULTS The mean treatment duration was 37 days in the CBRT arm and 49 days in the CRT arm. Treatment-related interruptions were less in the study group,17.3% in the study, and 27.2% in the control with insignificant P-value. Grade III laryngeal toxicity was significantly higher in the study group (P=0.029). Other acute grade I-III toxicities (pharyngeal, skin, mucositis, and salivary) were comparable in both CRT and CBRT arms. Grade IV toxicities were seen only in the CBRT arm but were resolved at the first follow-up. Haematological toxicities and renal toxicities were significantly higher in the CRT arm, with significant P-values of 0.0004 and 0.018, respectively. CONCLUSION In patients with locally advanced head and neck cancer, concomitant boost radiotherapy is well tolerated with acceptable local toxicity and minimal systemic toxicity as compared to conventional chemoradiation. It is a feasible option for patients with locally advanced head and neck cancer not fit for concurrent chemoradiation.

Abstract
BACKGROUND Personalised radiotherapy can improve treatment outcomes of patients with head and neck cancer (HNC), where currently a 'one-dose-fits-all' approach is the standard. The aim was to establish individualised outcome prediction based on multi-institutional international 'big-data' to facilitate risk-based stratification of patients with HNC. METHODS The data of 4611 HNC radiotherapy patients from three academic cancer centres were split into four cohorts: a training (n = 2241), independent test (n = 786), and external validation cohorts 1 (n = 1087) and 2 (n = 497). Tumour- and patient-related clinical variables were considered in a machine learning pipeline to predict overall survival (primary end-point) and local and regional tumour control (secondary end-points); serially, imaging features were considered for optional model improvement. Finally, patients were stratified into high-, intermediate-, and low-risk groups. RESULTS Performance score, AJCC8thstage, pack-years, and Age were identified as predictors for overall survival, demonstrating good performance in both the training cohort (c-index = 0.72 [95% CI, 0.66-0.77]) and in all three validation cohorts (c-indices: 0.76 [0.69-0.83], 0.73 [0.68-0.77], and 0.75 [0.68-0.80]). Excellent stratification of patients with HNC into high, intermediate, and low mortality risk was achieved; with 5-year overall survival rates of 17-46% for the high-risk group compared to 92-98% for the low-risk group. The addition of morphological image feature further improved the performance (c-index = 0.73 [0.64-0.81]). These models are integrated in a clinic-ready interactive web interface: https://uic-evl.github.io/hnc-predictor/ CONCLUSIONS: Robust model-based prediction was able to stratify patients with HNC in distinct high, intermediate, and low mortality risk groups. This can effectively be capitalised for personalised radiotherapy, e.g., for tumour radiation dose escalation/de-escalation.

Abstract
We investigated the effects of ablative dose irradiation on redistribution and radioresponse after the second irradiation in a mouse xenograft model, assuming stereotactic body radiotherapy (SBRT). A human tongue cancer cell line, SAS-Fucci, expressing the fluorescent ubiquitination-based cell cycle indicator (Fucci) that visualizes the cell cycle, was employed in this study. Tumor xenografts formed subcutaneously in nude mice (approximately 6 mm in diameter), with essentially no hypoxic regions, were irradiated at 10 Gy and G2 arrest kinetics were determined using histology sections and a real-time detection method. The second irradiation (10 Gy) was given at intervals of 0 h, 3 h, 1 day, and 4 days after the first irradiation, and tumor regrowth curves were obtained. It was revealed that the ratio of G2-arrested cells showed a much higher peak at 1 day postirradiation compared to 2 Gy, assuming conventional radiotherapy, and gradually decreased thereafter up to 4 days. Tumors irradiated at intervals of 0 h and 1 day demonstrated significantly higher radioresponses than other timings. We conclude that redistribution could contribute to the efficacy of SBRT.

Abstract
Primary tumor volume and hypoxic volume has previously not been convincingly related. 367 patients with head and neck squamous cell carcinoma from 21 different studies using hypoxia-PET The hypoxic volume increased significantly with primary tumor volume. In larger tumor the hypoxic fraction was significantly higher than in smaller tumors.
Background Hypoxia and large tumor volumes are negative prognostic factors for patients with head and neck squamous cell carcinoma (HNSCC) treated with radiation therapy (RT). PET-scanning with specific hypoxia-tracers (hypoxia-PET) can be used to non-invasively assess hypoxic tumor volume. Primary tumor volume is readily available for patients undergoing RT. However, the relationship between hypoxic volume and primary tumor volume is yet an open question. The current study investigates the hypotheses that larger tumors contain both a larger hypoxic volume and a higher hypoxic fraction. Methods PubMed and Embase were systematically searched to identify articles fulfilling the predefined criteria. Individual tumor data (primary tumor volume and hypoxic volume/fraction) was extracted. Relationship between hypoxic volume and primary tumor volume was investigated by linear regression. The correlation between hypoxic fraction and log2(primary tumor volume) was determined for each cohort and in a pooled analysis individual regression slopes and coefficients of determination (R2) were weighted according to cohort size. Results 21 relevant articles were identified and individual data from 367 patients was extracted, out of which 323 patients from 17 studies had quantifiable volumes of interest. A correlation between primary tumor volume and PET-determined hypoxic volume was found (P <.001, R2 = 0.46). Larger tumors had a significantly higher fraction of hypoxia compared with smaller tumors (P<.01). The weighted analysis of all studies revealed that for each doubling of the tumor volume, the hypoxic fraction increased by four percentage points. Conclusion This study shows correlations between primary tumor volume and hypoxic volume as well as primary tumor volume and the hypoxic fraction in patients with HNSCC. The findings suggest that not only do large tumors contain more cancer cells, they also have a higher proportion of potentially radioresistant hypoxic cells. This knowledge can be important when individualizing RT.

Abstract
OBJECTIVE To evaluate the role of curative intent concurrent chemoradiation (CCRT) vs radiation (RT) alone for T1-T3N0 HPV-positive and HPV-negative oropharyngeal squamous cell cancer (OPSCC). METHODS The NCDB was queried for patients diagnosed between 2010 and 2017 with cT1-3N0M0 OPSCC treated with definitive RT or CCRT. Univariable analysis (UVA) and multivariable analysis (MVA) Cox regression analysis was performed with OS as the endpoint. Propensity score matching (PSM) 1:1 was performed. Interaction test to assess heterogeneity of treatment effect. RESULTS A total of 2830 patients were queried. On MVA, CCRT was associated with improved OS for T3N0 tumors (HR 0.49; 95% CI 0.39-0.63) but not for T1N0 (HR 1.43; 95% CI 0.99-2.07) and T2N0 (HR 0.92; 95% CI 0.75-1.13). For T3 patients, CCRT improved OS for HPV-negative (HR 0.43; 95% CI 0.31-0.59) and HPV-positive tumors (HR 0.39; 95% CI 0.25-0.61). After PSM, CCRT was not statistically different to RT for patients with T1-2N0 HPV-negative tumors (HR 1.10; 95% CI 0.85-1.43; p = 0.48) and T1-2N0 HPV-positive tumors (HR 1.15; 95% CI 0.79-1.68; p = 0.45). After PSM, CCRT improved OS compared to RT alone for patients with T3N0 HPV-negative (HR 0.43; 95% CI 0.31-0.59; p < 0.01) and HPV-positive tumors (HR 0.39; 95 %CI 0.25-0.61; p < 0.01). CONCLUSIONS CCRT is associated with improved OS in HPV-positive and HPV-negative T3N0 OPSCC. RT alone vs. CCRT demonstrated similar OS for T1-T2N0 OPSCC for both HPV negative and HPV positive tumors.

Escalating a Biological Dose of Radiation in the Target Volume Applying Stereotactic Radiosurgery in Patients with Head and Neck Region Tumours. Biomedicines 2022; 10:biomedicines10071484. [PMID: 35884789 PMCID: PMC9313164 DOI: 10.3390/biomedicines10071484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 06/17/2022] [Accepted: 06/21/2022] [Indexed: 11/30/2022] Open
Abstract
Background: The treatment of head and neck tumours is a complicated process usually involving surgery, radiation therapy, and systemic treatment. Despite the multidisciplinary approach, treatment outcomes are still unsatisfactory, especially considering malignant tumours such as squamous cell carcinoma or sarcoma, where the frequency of recurrence has reached 50% of cases. The implementation of modern and precise methods of radiotherapy, such as a radiosurgery boost, may allow for the escalation of the biologically effective dose in the gross tumour volume and improve the results of treatment. Methods: The administration of a stereotactic radiotherapy boost can be done in two ways: an upfront boost followed by conventional radio(chemo)therapy or a direct boost after conventional radio(chemo)therapy. The boost dose depends on the primary or nodal tumour volume and localization regarding the organs at risk. It falls within the range of 10–18 Gy. Discussion: The collection of detailed data on the response of the disease to the radiosurgery boost combined with conventional radiotherapy as well as an assessment of early and late toxicities will contribute crucial information to the prospective modification of fractionated radiotherapy. In the case of beneficial findings, the stereotactic radiosurgery boost in the course of radio(chemo)therapy in patients with head and neck tumours will be able to replace traditional techniques of radiation, and radical schemes of treatment will be possible for future development.

Abstract
BACKGROUND The prescribed radiation dose to patients with oropharyngeal squamous cell carcinoma (OPSCC) is standardized, even if the prognosis for individual patients may differ. Easy-at-hand pre-treatment risk stratification methods are valuable to individualize therapy. In the current study we assessed the prognostic impact of primary tumor volume for p16-positive and p16-negative tumors and in relationship to other prognostic factors for outcome in patients with OPSCC treated with primary radiation therapy (RT). METHODS Five hundred twenty-three OPSCC patients with p16-status treated with primary RT (68.0 Gy to 73.1 Gy in 7 weeks, or 68.0 Gy in 4.5 weeks), with or without concurrent chemotherapy, within three prospective trials were included in the study. Local failure (LF), progression free survival (PFS) and overall survival (OS) in relationship to the size of the primary gross tumor volume (GTV-T) and other prognostic factors were investigated. Efficiency of intensified RT (RT with total dose 73.1 Gy or given within 4.5 weeks) was analyzed in relationship to tumor volume. RESULTS The volume of GTV-T and p16-status were found to be the strongest prognostic markers for LF, PFS and OS. For p16-positive tumors, an increase in tumor volume had a significantly higher negative prognostic impact compared with p16-negative tumors. Within a T-classification, patients with a smaller tumor, compared with a larger tumor, had a better prognosis. The importance of tumor volume remained after adjusting for nodal status, age, performance status, smoking status, sex, and hemoglobin-level. The adjusted hazard ratio for OS per cm3 increase in tumor volume was 2.3% (95% CI 0-4.9) for p16-positive and 1.3% (95% 0.3-2.2) for p16-negative. Exploratory analyses suggested that intensified RT could mitigate the negative impact of a large tumor volume. CONCLUSIONS Outcome for patients with OPSCC treated with RT is largely determined by tumor volume, even when adjusting for other established prognostic factors. Tumor volume is significantly more influential for patients with p16-positive tumors. Patients with large tumor volumes might benefit by intensified RT to improve survival.

Abstract
INTRODUCTION Radiation dose-escalation for head and neck cancer (HNC) patients aiming to improve cure rates is challenging due to the increased risk of unacceptable treatment-induced toxicities. With "Proton Image-guided Radiation Assignment for Therapeutic Escalation via Selection of locally advanced head and neck cancer patients" (PIRATES), we present a novel treatment approach that is designed to facilitate dose-escalation while minimizing the risk of dose-limiting toxicities for locally advanced HPV-negative HNC patients. The aim of this Phase I trial is to assess the safety & feasibility of PIRATES approach. METHODS The PIRATES protocol employs a multi-faceted dose-escalation approach to minimize the risk of dose-limiting toxicities (DLTs): 1) sparing surrounding normal tissue from extraneous dose with intensity-modulated proton therapy, 2) mid-treatment hybrid hyper-fractionation for radiobiologic normal tissue sparing; 3) Magnetic Resonance Imaging (MRI) guided mid-treatment boost volume adaptation, and 4) iso-effective restricted organ-at-risk dosing to mucosa and bone tissues.The time-to-event Bayesian optimal interval (TITE-BOIN) design is employed to address the challenge of the long DLT window of 6 months and find the maximum tolerated dose. The primary endpoint is unacceptable radiation-induced toxicities (Grade 4, mucositis, dermatitis, or Grade 3 myelopathy, osteoradionecrosis) occurring within 6 months following radiotherapy. The second endpoint is any grade 3 toxicity occurring in 3-6 months after radiation. DISCUSSION The PIRATES dose-escalation approach is designed to provide a safe avenue to intensify local treatment for HNC patients for whom therapy with conventional radiation dose levels is likely to fail. PIRATES aims to minimize the radiation damage to the tissue surrounding the tumor volume with the combination of proton therapy and adaptive radiotherapy and within the high dose tumor volume with hybrid hyper-fractionation and not boosting mucosal and bone tissues. Ultimately, if successful, PIRATES has the potential to safety increase local control rates in HNC patients with high loco-regional failure risk.Trial registration: ClinicalTrials.gov ID: NCT04870840; Registration date: May 4, 2021.Netherlands Trial Register ID: NL9603; Registration date: July 15, 2021.

Abstract
Background The advantage of up‐front neck dissection (UFND) followed by chemoradiotherapy (CRT) for hypopharyngeal cancer (HPC) with advanced neck involvement remains controversial. We aimed to determine the indications. Methods The data of 41 and 14 patients with stage IVA/B (T1–T3 and ≥N2a) HPC who underwent UFND followed by CRT and received CRT, respectively, were retrospectively analyzed and compared. Results The 5‐year overall survival (OS) and disease‐specific survival rates for the UFND and CRT groups were 61% and 52% (p = 0.1019), and 89% and 74% (p = 0.2333), respectively. Moreover, patients aged ≥70 years or those with a pulmonary disease history had a significantly poorer prognosis due to aspiration pneumonia in the UFND group. The 5‐year regional control (RC) for the UFND and CRT groups were 92% and 57%, respectively (p = 0.0001). Conclusions UFND followed by CRT was feasible with satisfactory RC. To further improve OS, aspiration pneumonia prevention is essential.

Cost-Effectiveness of Pembrolizumab Regimens for the First-Line Treatment of Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma in Argentina. Adv Ther 2021; 38:2613-2630. [PMID: 33855690 PMCID: PMC8107151 DOI: 10.1007/s12325-021-01656-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 02/04/2021] [Indexed: 10/26/2022]
Abstract
INTRODUCTION The phase III KEYNOTE-048 trial showed that the programmed death receptor 1 (PD-1) inhibitor pembrolizumab, in the combined positive score (CPS) ≥ 1 population and combined with platinum + 5-fluorouracil in the total population, improves survival over cetuximab + platinum + 5-fluorouracil in recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). We evaluated the cost-effectiveness of pembrolizumab as monotherapy in the CPS ≥ 1 population or combined with platinum + 5-fluorouracil in the total population versus cetuximab + platinum + 5-fluorouracil from the social security perspective in Argentina. METHODS A partitioned survival model projected costs and outcomes over 20 years with 3% annual discounting. Health state occupancy was modeled using KEYNOTE-048 Kaplan-Meier curves until the final analysis data cutoff, followed by parametric extrapolations guided by statistical criteria. Costs for initial and subsequent treatments, disease and adverse events management, and terminal care were included (AR $74.00 = 1 USD). Time-on-treatment and EuroQol five-dimension scores were taken from KEYNOTE-048. Utilities were derived using an Argentina-specific algorithm. RESULTS With pembrolizumab monotherapy, patients accrued 1.1040 additional life-years and 0.8768 additional quality-adjusted life-years (QALYs), for incremental cost-effectiveness ratios (ICERs) of AR $135,801/life-year and AR $170,985/QALY gained over cetuximab + platinum + 5-fluorouracil. Additional life-years and QALYs gained with pembrolizumab combination therapy versus cetuximab + platinum + 5-fluorouracil were 1.3296 and 1.0536, respectively (ICERs of AR $680,143/life-year and AR $858,306/QALY). Considering a threshold of AR $1,676,122/QALY gained, pembrolizumab monotherapy and combination therapy had an 88.0% and a 77.1% probability of being cost-effective, respectively. CONCLUSION Pembrolizumab either as monotherapy or in combination with chemotherapy offers substantial survival gains for patients with R/M HNSCC at small additional costs, making it a cost-effective treatment versus cetuximab + platinum + 5-FU in Argentina.

Abstract
BACKGROUND For human papilloma virus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC), management recommendations for patients with a single metastatic lymph node <6 cm in diameter remain nebulous, leading to treatment heterogeneity in this common subgroup of patients. METHODS We utilized the National Cancer Database to perform survival and multivariable analyses of patients with HPV+ OPSCC with one positive lymph node <6 cm and negative surgical margins. RESULTS We found that 5-year survival is comparable between patients who receive surgery and adjuvant radiation versus surgery alone. In multivariable analyses, we found no significant difference in the hazard ratio of overall survival after adjusting for various potential confounders. CONCLUSIONS These data suggest that patients with margin-negative HPV+ OPSCC with a single positive lymph node <6 cm have comparable survival with or without adjuvant radiation. Future studies exploring outcomes for this specific group in randomized-controlled trials will be critical for further evaluating these initial observations.

Abstract
The irradiation of non-malignant diseases, essentially for anti-inflammatory purpose, have been largely proposed and performed worldwide until the 1970-80s. At that time, the better assessment of the radio-induced malignancies, essentially in children and young patients, as well as the efficacy of the new anti-inflammatory drugs (steroids and non-steroids), led to the almost disappearance of those techniques, at least in France. In contrast, our German colleagues are still going on treating about 50,000 patients per year for non-malignant (more or less severe) diseases. After a short historical overview, the present article suggests that we were possibly going too far in the rejection of those low-dose irradiations for benign lesions. The recent emergence of new preclinical data, the better understanding of the risk of radio-induced secondary tumours (almost nil in the elderly), and the severity of some situations, such as the cytokine storm of the COVID-19, should probably lead us to reconsider those low - and sometimes very low (less than 1Gy) - irradiations for well-selected indications in the elderly.

Abstract
OBJECTIVES The number of citations an article receives is an important indication of its impact. The main objectives of this investigation provide readers with a practical guide in evaluating head and neck oncology literature and determine the characteristics of trends in ORL. METHODS This was a retrospective bibliometric analysis that did not involve human participant. The Thomson Reuters Web of Science was searched to determine the citations of all published HNO articles. Most cited 300 article analyzed and a total of 100 articles were included in our investigation under the topic search "Head AND NECK AND (cancer OR carcinoma OR oncology)." Articles include malignancies other than head and neck are excluded. The top 100 cited articles were selected and analyzed by 2 independent investigators. Country, Institution, First Author, Journal name, study design, cites per year information gathered and analyzed. RESULTS The journal with the highest number of top 100 cited articles was New England Journal Of Medicine with 19 paper, followed by The Journal of Clinical Oncology(17) and Cancer Research (12). The top article on the list (Radiotherapy plus cetuximab for squamous cell carcinoma of the head and neck-NEJM) has 2243 citations. A statistically significant association was found between the journal impact factor and the number of top 100 cited articles (P < .05). The United States had the highest number of articles (63). John Hopkins is differed from other institutions with 15 contributing articles. CONCLUSION Our analysis provides an insight into the citation frequency of top cited articles published in HNO to help recognize the quality of the works, discoveries and the trends steering the study of HNO. This is also a modern reading list for young HNO scientist.

Abstract
BACKGROUND A phase I-II study to evaluate the feasibility and efficacy of intensified, primary radiotherapy (RT) for Locally Advanced Head and Neck Squamous Cell Carcinoma (LAHNSCC) employing dose escalation by hyperfractionation, acceleration of treatment time, concomitant chemotherapy and hypoxic modification. METHODS Patients with HPV/p16- LAHNSCC receiving primary hyperfractionated, accelerated RT, 76 Gy/56 fx, 10 fx/week for 5½ weeks, concomitant weekly cisplatin (40 mg/m2) and nimorazole (HART-CN) were included. Primary endpoint was locoregional failure (LRF). Secondary endpoints were overall survival (OS) and toxicity. RESULTS 50 patients received HART-CN from 2013 to 2017. Median age was 60 years. Most patients had stage IV hypo- or oropharynx cancer with a heavy smoking history. All oropharyngeal cancers were HPV/p16-negative. Ninety-eight percent of patients completed RT, but compliance to cisplatin and nimorazole was lower. Median observation time was 44 months. LRF was diagnosed in 10 patients. All LRFs were in the high-dose CTV. The 3-year actuarial LRF was 21%, and OS was 74%. The peak incidence of acute toxicity showed that 67% of patients experienced severe dysphagia, 61% severe mucositis, and 78% were equipped with feeding tubes. Late severe morbidity was seen in 7 of 29 recurrence-free patients with at least 3 years of followup, who presented with either severe dysphagia (n = 2), severe xerostomia (n = 1), severe fibrosis of the neck (n = 3) or osteoradionecrosis (n = 1). Three were still tube dependent. CONCLUSION HART-CN is feasible in patients with HPV/p16- LAHNSCC in good health. Although acute toxicity was pronounced, the proportion of patients with late toxicity was acceptable and outcome at 3 years encouraging.

Abstract
BACKGROUND A large tumor volume negatively impacts the outcome of radiation therapy (RT). Altered fractionation (AF) can improve local control (LC) compared with conventional fractionation (CF). The aim of the present study was to investigate if response to AF differs with tumor volume in oropharyngeal cancer. METHODS Three hundred and twenty four patients with oropharyngeal cancer treated in a randomized, phase III trial comparing CF (2 Gy/d, 5 d/wk, 7 weeks, total dose 68 Gy) to AF (1.1 Gy + 2 Gy/d, 5 d/wk, 4.5 weeks, total dose 68 Gy) were analyzed. RESULTS Tumor volume had less impact on LC for patients treated with AF. There was an interaction between tumor volume and fractionation schedule (P = .039). This differential response was in favor of CF for small tumors and of AF for large tumors. CONCLUSION AF diminishes the importance of tumor volume for local tumor control in oropharyngeal cancer.

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: The study aimed to evaluate Hyperfractionated, Accelerated Radiotherapy (HART) with nimorazole for patients with head and neck squamous cell carcinoma (HNSCC) using loco-regional failure (LRF), overall survival (OS), early and late morbidity as endpoints. Material and methods: From February 2007 to January 2018, 295 patients with unresected HNSCC, T1-T4, N0-N3, M0, were treated with HART prescribed as 76 Gy in 56 fractions (fx), 10 fx weekly. IMRT was used in >90% of patients. No chemotherapy was given. Patients were prospectively registered in the DAHANCA database. Results: The median age was 64 years, 75% of patients were males. Primary sites were larynx (25%), pharynx (64%) and oral cavity (11%). In total, 59% were stage III-IV (UICC 2002). Of the 150 oropharyngeal cancer (OPC) patients, 42% were p16+. The proportion of patients receiving HART as planned was 97%. The median follow-up time was 66 months. Three-year actuarial LRF was 19% and OS was 66%. LRF was significantly higher for stage III-IV patients compared to stage I-II (25% vs. 11%, HR 2.12 [1.21-3.74]). The site-specific LRF rates were: for larynx 22% [12-32], hypopharynx 30% [16-45], non-p16+ oropharynx 15% [8-23], p16+ oropharynx 7% [1-13] and oral cavity 35% [18-53]. During therapy, 51% reported severe dysphagia and 60% required feeding tubes. The peak incidence of late, severe dysphagia and xerostomia was 21% and 9%, respectively. A comparison to historical data from previous DAHANCA trials showed that tumor control and morbidity are comparable to treatment with acceleration and/or chemo-radiation. Conclusions: HART represents an attractive approach for patients with HNSCC where treatment intensification is indicated.

Abstract
The goal in external beam radiotherapy (EBRT) for cancer is to maximize damage to the tumour while limiting toxic effects on the organs-at-risk. EBRT can be delivered via different modalities such as photons, protons and neutrons. The choice of an optimal modality depends on the anatomy of the irradiated area and the relative physical and biological properties of the modalities under consideration. There is no single universally dominant modality. We present the first-ever mathematical formulation of the optimal modality selection problem. We show that this problem can be tackled by solving the Karush-Kuhn-Tucker conditions of optimality, which reduce to an analytically tractable quartic equation. We perform numerical experiments to gain insights into the effect of biological and physical properties on the choice of an optimal modality or combination of modalities.

Abstract
Fractionation was established more than fifty years ago as the best way to obtain a differential effect between tumors and normal tissues. However, new technologies allowed today to spare critical organs from the radiation fields. And so protracted courses of irradiation are no longer required. Hypofractionation have clear practical advantages over classical fractionation: it saves the patient time; it saves money for public health system; it reduces pressure on radiotherapy units. In several localization, it has proved to be as efficient as classical fractionation without increasing late effects. In prostate cancer, some radiobiological considerations argue in favor of a better efficiency, but clinical trials did not demonstrated differences in biological control. In conclusion, for all diseases where hypofractionation was demonstrated efficient, it must be fully implemented. Invoice procedures must be adapted to maintain a sufficient level of reimbursement of radiotherapy centers.

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.

Abstract
Due to the rapid increase in the availability of patient data, there is significant interest in precision medicine that could facilitate the development of a personalized treatment plan for each patient on an individual basis. Radiation oncology is particularly suited for predictive machine learning (ML) models due to the enormous amount of diagnostic data used as input and therapeutic data generated as output. An emerging field in precision radiation oncology that can take advantage of ML approaches is radiogenomics, which is the study of the impact of genomic variations on the sensitivity of normal and tumor tissue to radiation. Currently, patients undergoing radiotherapy are treated using uniform dose constraints specific to the tumor and surrounding normal tissues. This is suboptimal in many ways. First, the dose that can be delivered to the target volume may be insufficient for control but is constrained by the surrounding normal tissue, as dose escalation can lead to significant morbidity and rare. Second, two patients with nearly identical dose distributions can have substantially different acute and late toxicities, resulting in lengthy treatment breaks and suboptimal control, or chronic morbidities leading to poor quality of life. Despite significant advances in radiogenomics, the magnitude of the genetic contribution to radiation response far exceeds our current understanding of individual risk variants. In the field of genomics, ML methods are being used to extract harder-to-detect knowledge, but these methods have yet to fully penetrate radiogenomics. Hence, the goal of this publication is to provide an overview of ML as it applies to radiogenomics. We begin with a brief history of radiogenomics and its relationship to precision medicine. We then introduce ML and compare it to statistical hypothesis testing to reflect on shared lessons and to avoid common pitfalls. Current ML approaches to genome-wide association studies are examined. The application of ML specifically to radiogenomics is next presented. We end with important lessons for the proper integration of ML into radiogenomics.

Abstract
The Authors present a review of randomized trials on non conventional fractionation in head and neck cancer radiotherapy with conventional fractionation as control arm. Hyperfractionation was studied in 5 trials, accelerated hyperfractionation in 4 trials and accelerated fractionation in 3 trials. Furthermore, the reviews of eminent Authors dealing with the above mentioned trials are summarized. In spite of improved local control rate reported with hyperfractionation, non conventional radiotherapy schedules are not yet recommended as routine clinical practice, but all the radiation oncologists are invited to join trials on this subject.

Abstract
Differences between late-responding (slowly proliferating) normal tissues and early-responding (rapidly proliferating) normal tissues and tumor cells and the event of tumor cell repopulation occurring during treatment have essentially led to the development of altered fractionation schemes. Altered fractionation regimens mainly refer to schedules utilising two or more (small dose) fractions per day for part of or for the entire treatment course. It must be underlined that a true standard or conventional fractionation regimen does not exist: no schedule is universally recognised as the standard of reference to be compared with. However, continental European and U.S. conventional regimens are the considered control arm with which the new experimental regimens have to be compared. For this reason they are generally recognised as the standards. The basic rationale for hyperfractionated or accelerated regimens respectively lies in the possibility (a) to deliver higher total doses reducing late-responding normal tissue damage, (b) to deliver total doses in a reduced overall treatment time to defeat tumor clonogen repopulation. Multiple fractions per day should not be delivered with interfraction intervals smaller than 6 hours. Clinical results of phase I-II and limited but convincing phase III randomised trials suggest that a therapeutic benefit can be achieved with new altered regimens.

Abstract
AIMS AND BACKGROUND To compare conventional fractionation (CF) radiation therapy (RT), arm A, versus a split-course accelerated hyperfractionated schedule (S-AHF), arm B, versus CFRT plus concomitant chemotherapy (CT), arm C, in terms of five-year survival and toxicity for squamous cell tumors of the oropharynx. METHODS AND STUDY DESIGN Between January 1993 and June 1998, 192 previously untreated patients with stage III and IV oropharyngeal carcinoma (excluding T1N1 and T2N1) were enrolled in a multicenter randomized phase III trial (ORO 93-01). In arms A and C, 66 to 70 Gy in 33 to 35 fractions was administered five days a week for six and a half to seven weeks. In arm B, the dose delivered was 64 to 67.2 Gy in two fractions of 1.6 Gy every day, five days a week, with a planned two-week split at 38.4 Gy. In arm C the CT regimen consisted of three cycles of carboplatin and 5-fluorouracil (CBDCA 75 mg/m2 on days 1 to 4 and 5-FU 1000 mg/m2 i.v. on days 1 to 4 every 28 days). RESULTS No statistically significant difference was found in five-year overall survival (P = 0.39): 21% for arm A, 21% for arm B, and 40% for arm C. Similarly, there was no statistically significant difference in terms of five-year relapse-free survival: 15% for arm A, 17% for arm B, and 36% for arm C. There was a slight trend towards better five-year locoregional control (P = 0.07) for the combined arm: patients without locoregional relapse were 48% in arm C, 21% in arm A and 18% in arm B. Locoregional control was significantly better when arm C was compared with arms A and B combined (P = 0.02; arm A+B 20%; arm C 48%). Distant metastases were fairly balanced in the three arms (A: 14; B: 9; C: 11), with a tendency towards more frequent isolated distant metastasis development in arm C (8 of 11 [72%] versus 7 of 23 [30%] in arms A+B). Five-year second-tumor-free survival was 85%. The 13 second tumors were equally distributed and were mainly correlated with tobacco and alcohol consumption (five lung, two esophagus, two oral cavity, one larynx, one pancreas, one hepatocarcinoma, one myeloma). Arm C showed slightly more G3+ late side effects involving subcutaneous tissues and mucosa, although significant late sequelae were relatively uncommon and the mucosal side effects were mostly transient. The occurrence of persistent G3 xerostomia was comparable in the three treatment arms. CONCLUSIONS The results obtained with the combination of CT and RT compared with RT alone did not reach statistical significance, but combined treatment almost doubled the five-year overall survival, relapse-free survival and locoregional control rate. Patients with advanced squamous cell carcinomas of the oropharynx who are medically suitable for the combined approach should be treated with a combination of radiotherapy and chemotherapy. The occurrence of second tumors is relatively common in these patients and may contribute substantially to the causes of death.

Abstract
Aims This study was undertaken to determine the outcome of patients with oropharyngeal cancer treated at the Radiotherapy Department of the Santa Chiara Hospital (Trento, Italy) with brachytherapy alone or combined with external beam radiotherapy (EBRT). Material and methods We retrospectively reviewed the medical records of 87 patients with squamous cell carcinoma of the oropharynx treated by radiation therapy between January 1986 and September 1999. The median age was 59 years and all patients had a minimum follow-up of one year. Tumor locations were 46 tonsillar region, 31 soft palate and 10 base of the tongue. The patients were staged as follows: 41 T1, 35 T2, 11 T3 with 70 N0, 9 N1 and 8 N2. They received either brachytherapy alone (14 patients) or a combination of external beam irradiation and brachytherapy (73 patients) using an afterloading iridium technique in a plastic tube. Results Overall primary tumor control, including salvage surgery, was 81/87 (93%). Control of metastatic cervical adenopathy was as follows: clinical stage N1, 5/9 patients; N2, 2/8 patients. The estimated five-year cause-specific survival and overall survival rates were 81% and 47%, respectively. After interstitial irradiation severe complications were limited to one case of osteoradionecrosis of the mandible and seven cases of mucosal ulcer. Conclusion This study confirms that iridium-192 interstitial implant alone or as a boost after external beam irradiation is a safe and effective therapy in the management of oropharyngeal carcinomas.

Abstract
BACKGROUND The current treatment options for cancer of the base of the tongue and glosso-epiglottic region are surgery, radiotherapy, or a combination of both modalities. Comparisons between different modalities are not common in the literature, and a real standard of treatment has not yet been established. The purpose of our study was to evaluate the results of treatment in a large series of patients from 18 Italian institutions in relation to the main treatment adopted. METHODS The present study is a retrospective survey. The series was divided into a combined surgery group and a radiotherapy group. The Kaplan-Meier method and the log-rank test were used for survival calculations and comparisons. RESULTS Eight hundred patients were registered (25.7% stage III and 62% stage IV), 336 in the surgery and 372 in the radiotherapy group. Conventional fractionation was adopted in almost all cases. The five-year overall and disease free survival of the whole series was 32% and 38%, respectively. Survival was slightly better for patients with tumors of the glosso-epiglottic region than for those with a tumor of the base of the tongue. Five-year disease-free survival was 55% for patients treated with surgery +/- radiochemotherapy and 26% for those submitted to radiotherapy alone or in combination with chemotherapy. As far as the total dose and the treatment duration were concerned, only 26% of the patients of the radiotherapy group met the established criteria of adequacy, but in patients with adequate radiation the control rate was better only for small tumors (T1-T2). CONCLUSIONS The results in patients treated with surgery +/- postoperative radiotherapy were similar to or better than those reported in the best series in the literature. By contrast, the survival rate of irradiated patients was lower than those reported by other centers.

Abstract
Background A number of oral toxicity scoring systems have been described, but their direct comparison has rarely been undertaken and little data exists. An impediment to mucositis research has been the lack of an accepted, validated scoring system. The objective of this study was to design a test and validation of scoring systems. Materials and methods Forty-three patients with head and neck malignancies who had been irradiated were evaluated. Five different mucositis scoring systems (World Health Organization, Radiation Therapy Oncology Group, “Hickey”, “Van der Schueren” and “Makkonen”) were compared with each other. Results Daily mucositis scores demonstrated a high correlation among scoring systems (P <0.05 and coefficient of correlation κ and r = 0.5 - 0.95). Objective mucositis scores demonstrated a strong correlation with symptoms. Conclusions All scoring systems were equally valid. The exact grading of mucositis is achieved by combining clinical information about pain and nutritional status with oral mucosal reactions.

Abstract
BACKGROUND AND PURPOSE Accelerated repopulation (AR) can compromise tumor control after conventional radiotherapy for fast-growing tumors. Standard AR models assume it begins at a fixed time, with repopulation rates independent of the number of clonogens killed. We investigate the validity and significance of an alternative model where onset-time and rate of AR depend on the number of clonogens killed, and thus on dose and dose-fractionation. MATERIALS AND METHODS We analyzed tumor control (TCP) from randomized trials for head and neck cancer (HNC, 7283 patients), featuring wide ranges of doses, times, and fractionation-schemes. We used the linear-quadratic model with the standard dose-independent AR model, or with an alternative dose-dependent model, where AR onset and rate depend on clonogen killing. RESULTS The alternative dose-dependent model of AR provides significantly-improved descriptions of a wide range of randomized clinical data, relative to the standard dose-independent model. This preferred model predicts that, for currently-used HNC fractionation schemes, the last 5 fractions do not increase TCP, but simply compensate for increased accelerated repopulation. CONCLUSIONS The preferred dose-dependent AR model predicts that, for standard fractionation schemes currently used to treat HNC, the final week (5 fractions) could be eliminated without compromising TCP, but resulting in significantly decreased late sequelae due to the lower overall dose.

Abstract
BACKGROUND To evaluate the treatment tolerance and clinical outcomes in patients aged 70 years and older with locally advanced oropharyngeal cancer treated by definitive intensity-modulated radiation therapy (IMRT). PATIENTS AND METHODS We retrospectively analyzed 15 consecutive elderly patients, with histologically-proven squamous cell carcinoma of the oropharynx, staged T3-4 with or without involved lymph nodes at diagnosis, who received definitive sequential IMRT (70 Gy; 2 Gy/fraction). Adult Comorbidity Evaluation-27 (ACE-27) score was calculated and its influence on treatment tolerance and clinical outcomes was analyzed. RESULTS A total of 15 patients were included with a median age of 77 years (range=70-88 years). At baseline, 8 patients (53.3%) had an ACE-27 score of 1, and the remainder (n=7, 46.7%) had a comorbidity index of 0. All patients completed programmed IMRT treatment, without any reduction of total dose. Oral pain and mucositis were the most common acute side-effects, classified as grade 3 in 6 patients (40%) only. Xerostomia was reported in 13 patients (86.7%), without severe manifestation. There was no hematological toxicity. ACE-27 score was not related to higher severe acute toxicity. No patients experienced grade 3 or more late toxicity. Five-year overall survival and disease-free survival rates were 63.6% (95% confidence interval=32.7-83.3%) and 55% (95% confidence interval=24.4-77.6%), respectively. Comorbidity score did not influence survival outcomes, both overall survival (p=0.46) and disease-free survival (p=0.55). CONCLUSION Treatment tolerance, as well as survival outcomes were good in elderly oropharyngeal cancer patients treated with definitive sequential IMRT. Due to age and comorbidity, no dose or volume reduction for IMRT should be considered in this setting of patients. A prospective randomized trial with a large sample size should be conducted to confirm our results.

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
Objective The goal of this study was to evaluate the efficacy and safety of modified (accelerated and/or hyperfractionated) radiotherapy in the treatment of esophageal carcinoma, compared with conventional radiotherapy. Methods Studies published in the PubMed, Cochrane Library, EMBASE, CBM, VIP, CNKI and Wanfang databases in the most recent two decades were searched for use in this meta-analysis. Only randomized controlled trials were included. The heterogeneity analysis and calculation of the pooled odds ratio (OR) were performed using RevMan 5.3 software. The assessment of publication bias and sensitivity analyses was conducted using Stata 13.0 software. Results Twenty trials with a total of 1,742 Chinese patients who met the inclusion criteria were included. The pooled results showed that modified radiotherapy improved the response rate compared with conventional schedules (OR =3.90, 95% confidence interval [CI]: 2.47–6.16, P<0.001). Favorable results were observed for the 1-year (OR =2.58, 95% CI: 2.05–3.26, P<0.001), 3-year (OR =2.30, 95% CI: 1.83–2.89, P<0.001) and 5-year (OR =2.36, 95% CI: 1.74–3.21, P<0.001) overall survival and for the 1-year (OR =2.46, 95% CI: 1.72–3.51, P<0.001), 3-year (OR =2.08, 95% CI: 1.49–2.90, P<0.001) and 5-year (OR =2.15, 95% CI: 1.38–3.34, P<0.001) overall local control rate in the modified fractionation radiotherapy group. However, the altered radiotherapy increased the risk of acute radiation esophagitis (OR =1.70, 95% CI: 1.27–2.28, P<0.001) and acute radiation tracheitis (OR =1.47, 95% CI: 1.09–1.99, P=0.01). No significant differences in the risk of esophageal perforation (OR =1.30, 95% CI: 0.51–3.32, P=0.58) or esophagorrhagia (OR =0.88, 95% CI: 0.41–1.88, P=0.74) were found between the two groups. Conclusion Chinese patients with squamous cell esophagus carcinomas gained a significant benefit in terms of the response rate, survival and local control rates from the modified fractionation radiotherapy, but also had an increased risk of acute radiation reactions. Otherwise, there was no observed statistically significant difference in terms of early adverse reactions.

Shaikh T, Handorf EA, Murphy CT, Mehra R, Ridge JA, Galloway TJ. The Impact of Radiation Treatment Time on Survival in Patients With Head and Neck Cancer. Int J Radiat Oncol Biol Phys 2016; 96:967-975. [PMID: 27869097 DOI: 10.1016/j.ijrobp.2016.08.046] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Revised: 08/05/2016] [Accepted: 08/29/2016] [Indexed: 12/26/2022]
Abstract
PURPOSE To assess the impact of radiation treatment time (RTT) in head and neck cancers on overall survival (OS) in the era of chemoradiation. METHODS AND MATERIALS Patients with diagnoses of tongue, hypopharynx, larynx, oropharynx, or tonsil cancer were identified by use of the National Cancer Database. RTT was defined as date of first radiation treatment to date of last radiation treatment. In the definitive setting, prolonged RTT was defined as >56 days, accelerated RTT was defined as <47 days, and standard RTT was defined as 47 to 56 days. In the postoperative setting, prolonged RTT was defined as >49 days, accelerated RTT was defined as <40 days, and standard RTT was defined as 40 to 49 days. We used χ2 tests to identify predictors of RTT. The Kaplan-Meier method was used to compare OS among groups. Cox proportional hazards model was used for OS analysis in patients with known comorbidity status. RESULTS 19,531 patients were included; 12,987 (67%) had a standard RTT, 4,369 (34%) had an accelerated RTT, and 2,165 (11%) had a prolonged RTT. On multivariable analysis, accelerated RTT (hazard ratio [HR] 0.84; 95% confidence interval [CI] 0.73-0.97) was associated with an improved OS, and prolonged RTT (HR 1.25; 95% CI 1.14-1.37) was associated with a worse OS relative to standard RTT. When the 9,200 (47%) patients receiving definitive concurrent chemoradiation were examined, prolonged RTT (HR 1.29; 95% CI 1.11-1.50) was associated with a worse OS relative to standard RTT, whereas there was no significant association between accelerated RTT and OS (HR 0.76; 95% CI 0.57-1.01). CONCLUSION Prolonged RTT is associated with worse OS in patients receiving radiation therapy for head and neck cancer, even in the setting of chemoradiation. Expeditious completion of radiation should continue to be a quality metric for the management of head and neck malignancies.

Severe late dysphagia and cause of death after concurrent chemoradiation for larynx cancer in patients eligible for RTOG 91-11. Oral Oncol 2016; 57:21-6. [PMID: 27208840 DOI: 10.1016/j.oraloncology.2016.03.014] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2016] [Revised: 03/14/2016] [Accepted: 03/15/2016] [Indexed: 12/19/2022]
Abstract
PURPOSE The long-term results of RTOG 91-11 suggested increased deaths not attributed to larynx cancer after concomitant chemoradiotherapy (CRT) despite no apparent increase in late effects. Because the timing of events was not reported by RTOG 91-11, one possibility is that severe late dysphagia (SLD) develops beyond five years and leads to unreported treatment-related deaths. Here we explore the timing of SLD after CRT. METHODS Patients who would have met eligibility criteria for RTOG 91-11 and were treated with CRT between 1993 and 2013 were identified. Events occurring beyond 3months after treatment and suggestive of SLD were recorded including esophageal stricture dilations, hospital admissions for aspiration pneumonia or feeding-tube insertion. Feeding-tube dependence beyond one year was also considered SLD. The cumulative incidence of SLD and its components was quantified using Gray's competing risk analysis with recurrence or death considered competing risks. RESULTS Eighty-four patients were included with a median follow-up of 43months. The 5-year overall survival was 70% (95% CI 58-80%). No death was directly a result of treatment-induced late dysphagia. The 5-year incidence of SLD was 26.5%. While 15 of 18 (83%) first stricture dilations occurred within 5years after CRT, 3 of 5 (60%) aspiration admissions and 5 of 8 late feeding tube insertions occurred beyond five years from CRT. CONCLUSIONS SLD is common after CRT for larynx cancer and can occur beyond 5years from the end of treatment, emphasizing the importance of survivorship follow-up. Despite the incidence of SLD, death related to dysphagia is uncommon.
