Abstract
PURPOSE/OBJECTIVE(S) To report the results of a phase I-II study on SBRT for early glottic cancer. MATERIALS/METHODS This a prospective study at a single Institution enrolling patients with T1 glottic cancer. The true vocal cords (TVC) were divided into thirds and the third(s) containing disease prescribed 36 Gy in 3 fractions. The portions of the TVCs next to the involved one were planned to receive 30 Gy in 3 fxs. SBRT was delivered by a LINAC-based approach using multiple arcs. Toxicity was scored by CTCAE and late events were considered those occurring 3 months after SBRT. Voice quality was investigated by the voice handicap index (VHI) at regular intervals. The planned sample size was 75 patients. RESULTS Accrual was discontinued after 33 patients due to concerns for late toxicity. T stage was as follows: T1a: 23 pts (69.7%); T1b: 10 pts (30.3%). All patients received the planned treatment and the median follow-up time is 51.5 months (IQR: 47.9-61.0 months). At last follow up, all patients are alive and without evidence of disease but two patients who died for intercurrent causes. The local control rate is 100% at 4 yrs. Six patients (18.2%) developed soft tissue necrosis (N=4) or cartilage necrosis (N=2) after a median time of 14.9 months from SBRT. Five out of 6 necrotic events were observed in patients who kept smoking and/or had a recent COVID infection. All 4 soft tissue events healed with conservative therapy. After an initial deterioration the average VHI score significantly improved at 6 months over baseline. CONCLUSION SBRT to 36 Gy in 3 fractions is highly effective in controlling T1 TVC carcinoma, but necrosis, though mostly transient, is a concern. Based on the present results, a reduction in total dose as well as a more accurate patient selection are warranted.

Abstract
The treatment of head and neck cancers (HNCs) encompasses a complex paradigm involving a combination of surgery, radiotherapy, and systemic treatment. Locoregional recurrence is a common cause of treatment failure, and few patients are suitable for salvage surgery. Reirradiation with conventional radiation techniques is challenging due to normal tissue tolerance limits and the risk of significant toxicities. Stereotactic body radiotherapy (SBRT) has emerged as a highly conformal modality that offers the potential for cure while limiting the dose to surrounding tissue. There is also growing research that shows that those with oligometastatic disease can benefit from curative intent local ablative therapies such as SBRT. This review will look at published evidence regarding the use of SBRT in locoregional recurrent and oligometastatic HNCs.

Abstract
Background and purpose Radiotherapy (RT) is a mainstay component of treatment for patients with head and neck squamous cell carcinoma (HNSCC), but responses vary. As RT relies upon oxidative damage, antioxidant expression in response to RT-induced reactive oxygen species (ROS) could compromise treatment response. We aimed to examine local and systemic antioxidant responses to increased RT-induced ROS in relation to treatment success. Materials and methods Nuclear factor erythroid 2-related factor 2 (NRF2), the main antioxidant transcription factor, was immunofluorescently stained in FaDu cells and in tumor biopsies of patients with oral cavity/oropharynx HNSCC before and after five fractions of RT. Besides, total antioxidant capacity (TAC) was analyzed in HNSCC tumor cells in vitro and in serum of HNSCC patients before, during, and after RT. Results Data revealed an increase in NRF2 expression and TAC in head and neck cancer cells in vitro over the course of 5 daily fractions of 2 Gy. In accordance, also in patients' tumors NRF2 expression increased, which was associated with increased serum TAC during RT. Increasing serum TAC was related to impaired local tumor control. Conclusion Radiation induced NRF2 expression and upregulated TAC, which may compromise the effect of RT-induced ROS. Changes in serum TAC during RT could serve as a novel predictor of treatment outcome in HNSCC patients.Medical Ethics Review Committee (CMO) approval - CMO number: 2007/104.

Abstract
INTRODUCTION Reirradiation (reRT) of locally recurrent/second primary tumors of the head and neck region is a potentially curative treatment for patients not candidate to salvage surgery. Aim of the present study is to summarize available literature on both prognostic factors and indications to curative reRT in this clinical setting. MATERIALS AND METHODS A narrative review of the literature was performed on two topics: (1) patients' selection according to prognostic factors and (2) dosimetric feasibility of reRT. Postoperative reRT and palliative intent treatments were out of the scope of this work. RESULTS Patient-tumor and treatment-related prognostic factors were analyzed, together with dosimetric parameters concerning target volume and organs at risk. Based on available evidence, a stepwise approach has been proposed aiming to provide a useful tool to identify suitable candidates for curative reRT in clinical practice. This was then applied to two clinical cases, proposed at the end of this work. CONCLUSION A second course of RT in head and neck recurrence/second primary tumors is a personalized approach that can be offered to selected patients only in centers with expertise and dedicated equipment following a multidisciplinary team discussion.

Abstract
Stereotactic body radiation therapy (SBRT) is a precise and conformal radiation therapy (RT) that aims to deliver a high dose of radiation to the tumor whilst sparing surrounding normal tissue, making it an attractive option for head and neck cancer (HNC) patients who are not suitable for the traditional long course of RT with comprehensive RT target volume. Definitive SBRT for HNC has been investigated in different settings, including early stage glottis cancer, and as an alternative to brachytherapy boost after external beam RT. It is also used as a primary treatment option for elderly or medically unfit patients. More recently, an SBRT combination with immunotherapy in the neoadjuvant setting for HNC showed promising results. Salvage or adjuvant SBRT for HNC can be used in appropriately selected cases. Future studies are warranted to determine the optimum dose and fractionation schedules in any of these indications.

Abstract
Head and neck cancer is a kind of cancer which can be eradicated from radical radiation therapy. However, with best efforts, nearly 40% patients will experience locoregional recurrence. Locoregional recurrence is the main cause of cancer-related death in head and neck cancers, so local treatments play a key role in improving progression free survival. In the last decades, radiation techniques have been tremendously developed, highly conformal radiation techniques such as intensity-modulated radiotherapy, stereotactic body radiation therapy, brachytherapy and proton or heavy ion radiation therapy have their unique radiobiological advances. Although reirradiation is widely used in clinical practice, but little is known when comparing the different techniques. In this review, we will provide a comprehensive overview of the role of reirradiation in recurrent head and neck cancers including radiation techniques, patient selection, overall clinical benefits, and toxicities.

INTRODUCTION Reirradiation (reRT) of local recurrent/second primary tumors of the head and neck represents a potential curative treatment for patients not candidate to a salvage surgery. Aim of the present study is to summarize literature data on modern radiation techniques and fractionations used in this setting of patients. MATERIALS AND METHODS A narrative review of the literature was conducted on three topics: (1) target volume delineation (2) reRT dose and techniques and (3) ongoing studies. Patients treated with postoperative reRT and palliative intent were not considered for the current analysis. RESULTS Recommendations on the target volume contouring have been reported. 3D-Conformal Radiotherapy, Intensity Modulated Radiotherapy, Stereotactic body Radiotherapy Intraoperative Radiotherapy, Brachytherapy and Charged Particles have been analyzed in terms of indication and fractionation in the field of reRT. Ongoing studies on the topic have been reported for IMRT and Charged Particles. Moreover, according to literature data a stepwise approach has been proposed aiming to provide a useful tool to select patients candidate to a curative reRT in daily clinical practice. Two clinical cases were also provided for its application. CONCLUSION Different radiation techniques and fractionations can be used for a second course of radiotherapy in patients with recurrent/second primary tumor of head and neck region. Tumor characteristics as well as radiobiological considerations should be take into account to define the best reRT approach.

Abstract
BACKGROUND In the management of head and neck cancer (HNC) patients, local recurrence is a common cause of treatment failure. Only a few patients with recurrent HNC (rHNC) are eligible for salvage surgery and the majority of patients receive systemic therapy and radiotherapy. In recent years, with the development of irradiation technology, radiotherapy for rHNC patients has markedly attracted clinicians' attention and its therapeutic effects on patients with end-stage cancer are worthy of investigation as well. METHODS Several studies have investigated the role of radiotherapy in the treatment of rHNC patients. We reviewed retrospective reports and prospective trials published in recent decades that concentrated on the management of rHNC. RESULTS A growing body of evidence supported the application of irradiation to rHNC patients. According to the results of this review, current radiotherapy could achieve a better efficacy with a lower incidence of toxicity. CONCLUSION Radiotherapy is a promising treatment for rHNC patients.

Comparison of Photon Isoeffective Dose Models Based on In Vitro and In Vivo Radiobiological Experiments for Head and Neck Cancer Treated with BNCT. Radiat Res 2022; 198:134-144.

Abstract
Boron neutron capture therapy (BNCT) is a treatment modality for cancer that involves radiations of different qualities. A formalism that proved suitable to compute doses in photon-equivalent units is the photon isoeffective dose model. This study addresses the question whether considering in vitro or in vivo radiobiological studies to determine the parameters involved in photon isoeffective dose calculations affects the consistency of the model predictions. The analysis is focused on head and neck squamous cell carcinomas (HNSCC), a main target that proved to respond to BNCT. The photon isoeffective dose model for HNSCC with parameters from in vitro studies using the primary human cell line UT-SCC-16A was introduced and compared to the one previously reported with parameters from an in vivo oral cancer model in rodents. Both models were first compared in a simple scenario by means of tumor dose and control probability calculations. Then, the clinical impact of the different dose models was assessed from the analysis of a group of squamous cell carcinomas (SCC) patients treated with BNCT. Traditional dose calculations using the relative biological effectiveness factors derived from the SCC cell line were also analyzed. Predictions of tumor control from the evaluated models were compared to the patients' outcome. The quantification of the biological effectiveness of the different radiations revealed that relative biological effectiveness/compound biological effectiveness (RBE/CBE) factors for the SCC cell line are up to 20% higher than those assumed in clinical BNCT, highlighting the importance of using experimental data intimately linked to the tumor type to derive the model's parameters. The comparison of the different models showed that photon isoeffective doses based on in vitro data are generally greater than those from in vivo data (∼8-16% for total tumor absorbed doses of 10-15 Gy). However, the predictive power of the two models was not affected by these differences: both models fulfilled conditions to guarantee a good predictive performance and gave predictions statistically compatible with the clinical outcome. On the other hand, doses computed with the traditional model were substantially larger than those obtained with both photon isoeffective models. Moreover, the traditional model is statistically rejected, which reinforces the assertion that its inconsistencies are intrinsic and not due to the use of RBE/CBE factors obtained for a tumor type different from HN cancer. The results suggest that the nature of the radiobiological data would not affect the consistency of the photon isoeffective dose model in the studied cases of SCC head and neck cancer treated with BPA-based BNCT.

Abstract
BACKGROUND Re-treatment of recurrent or second primary head and neck cancers occurring in a previously irradiated field is complex. Few guidelines exist to support practice. METHODS We performed an updated literature search of peer-reviewed journals in a systematic fashion. Search terms, key questions, and associated clinical case variants were formed by panel consensus. The literature search informed the committee during a blinded vote on the appropriateness of treatment options via the modified Delphi method. RESULTS The final number of citations retained for review was 274. These informed five key questions, which focused on patient selection, adjuvant re-irradiation, definitive re-irradiation, stereotactic body radiation (SBRT), and re-irradiation to treat non-squamous cancer. Results of the consensus voting are presented along with discussion of the most current evidence. CONCLUSIONS This provides updated evidence-based recommendations and guidelines for the re-treatment of recurrent or second primary cancer of the head and neck.

Biomed J 2021; 45:838-846. [PMID: 34749016 DOI: 10.1016/j.bj.2021.10.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 10/28/2021] [Accepted: 10/31/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The aim of the study was to explore the treatment outcomes and prognostic factors for patients with previously irradiated but unresectable recurrent head and neck squamous cell carcinoma (rHNSCC) treated by stereotactic body radiotherapy (SBRT) plus cetuximab at a single institute in Taiwan. METHODS From February 2016 to March 2019, 74 patients with previously irradiated but unresectable rHNSCC were treated with SBRT plus cetuximab. All patients received irradiation to the gross tumor and/or nodal area with 40-50 Gy in five fractions, with each fraction interval ≥ 2 days over a 2-week period by using the CyberKnife M6 machine. An18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) scan was performed before treatment for treatment target delineation (n = 74) and 2 months later for response evaluation (n = 60). The median follow-up time was 9 months (range 1-36 months). RESULTS The treatment response rate was complete response: 25.0%, partial response: 41.7%, stable disease: 11.7%, and progressive disease: 21.7% based on the criteria of the Response Evaluation Criteria in Solid Tumors (n = 72) and complete metabolic response: 21.7%, partial metabolic response: 51.7%, stable metabolic disease: 13.3%, and progressive metabolic disease: 13.3% based on PET-CT (n = 60), respectively. The 1-/2-year overall survival (OS) and progression-free survival (PFS) rates were 42.8%/22.0% and 40.5%/19.0%, respectively. In the logistic regression model, a re-irradiation interval > 12 months was observed to be the only significant prognostic factor for a favorable treatment response. In the Cox proportional hazards model, a re-irradiation interval > 12 months and gross tumor volume (GTV) ≦ 50 ml were favorable prognostic factors of OS and PFS. CONCLUSION SBRT plus cetuximab provides a promising salvage strategy for those patients with previously irradiated but unresectable rHNSCC, especially those with a re-irradiation interval > 12 months or GTV ≦ 50 ml.

Abstract
Radiation therapy remains at the center of head and neck cancer treatment. With improvements in treatment delivery, radiation therapy has become an affective ablative modality for head and neck cancers. Immune checkpoint inhibitors are now also playing a more active role both in the locally advanced and metastatic setting. With improved systemic options, local noninvasive modalities including radiation therapy are playing a critical role in overcoming resistance in head and neck cancer. The aim of this review is to describe the role of radiation therapy in modulating the tumor microenvironment and how radiation dose, fractionation and treatment field can impact the immune system and potentially effect outcomes when combined with immunotherapy. The review will encompass several common scenarios where radiation is used to improve outcomes and overcome potential resistance that may develop with immunotherapy in head and neck squamous cell carcinoma (HNSCC), including upfront locally advanced disease receiving definitive radiation and recurrent disease undergoing re-irradiation. Lastly, we will review the potential toxicities of combined therapy and future directions of their role in the management of HNSCC.

Abstract
OBJECTIVES Stereotactic radiotherapy (SBRT) is gaining popularity although its use in head and neck cancer (HNC) is not well defined. The primary objective was to review the published evidence regarding the use of stereotactic radiotherapy in HNC. METHODS A literature search was performed by using MEDLINE and EMBASE databases for eligible studies from 2000 to 2019 and 26 relevant studies were identified. RESULTS Literature demonstrates a heterogeneous use of this technique with regards to patient population, primary or salvage treatment, dose fractionation regimens, outcomes and follow-up protocols. Carotid blow out syndrome is a risk as with other forms of reirradiation but alternative treatment regimens may reduce this risk. CONCLUSION At present there is a lack of evidence regarding SBRT as a primary treatment option for HNC and definitive answers regarding efficacy and tolerability cannot be provided but there is growing evidence that SBRT reirradiation regimens are safe and effective. In lieu of evidence from large Phase III trials, we define appropriate organ at risk constraints and prescription doses, with accurate plan summation approaches. Prospective randomised trials are warranted to validate improved treatment outcomes and acceptable treatment morbidity. ADVANCES IN KNOWLEDGE This article provides a comprehensive review of evidence of use of stereotactic radiotherapy in HNC site (either as a primary treatment or as reirradiation). We also provide an evidence-based approach to the implementation and practical consideration of stereotactic radiotherapy in HNC.

Abstract
Management of patients with recurrent head and neck cancer remains a challenge for the surgeon as well as the treating radiation oncologist. Even in the era of modern radiotherapy, the rate of severe toxicity remains high with unsatisfactory treatment results. Intensity-modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), and heavy-ion irradiation have all emerged as highly conformal and precise techniques that offer many radiobiological advantages in various clinical situations. Although re-irradiation is now widespread in clinical practice, little is known about the differences in treatment response and toxicity using diverse re-irradiation techniques. In this review, we provide a comprehensive overview of the role of radiation therapy in recurrent or second primary head and neck cancer including patient selection, therapeutic outcome, and risk using different re-irradiation techniques. Critical review of published evidence on IMRT, SBRT, and heavy-ion full-dose re-irradiation is presented including data on locoregional control, overall survival, and toxicity.

Abstract
BACKGROUND Recent advances in diagnostic methods and in radiotherapy now increasingly enable repeat radiotherapy with curative intent for the treatment of previously irradiated lesions. In this review, we present data on oncological outcomes and on acute and late sequelae, as far as these are currently known, in patients with head and neck tumors (HNT) or prostate cancer (PCa) who underwent repeat radiotherapy after prior radiotherapy with curative intent. METHODS This review is based on clinical series with over 20 patients that were published between May 1998 and April 2018 (HNT) or between October 1998 and October 2018 (PCa) and were retrieved by a search in the PubMed database. RESULTS Most of the clinical series retrieved were retrospective and uncontrolled. There were 16 studies that included 2678 patients with recurrent head and neck tumors, and 8 that included 245 patients with recurrent prostate cancer. In patients with squamous cell carcinoma of the head and neck, intensity-modulated radio - therapy (IMRT) and stereotactic body radiotherapy (SBRT) yielded three-year survival rates of 47-57% but also produced substantial acute and late adverse effects. Most of the studies concerning recurrent PCa involved small patient groups. In these studies, repeat radiotherapy with SBRT yielded tumor control rates of 40-80% after 11-24 months of follow-up, with only mild acute toxicity. CONCLUSION Although no comparative studies are available, it seems that modern external beam radiotherapy techniques can be used for repeat radiotherapy of locally recurrent head and neck tumors with curative intent after careful patient selection. Repeat radiotherapy of PCa must still be considered experimental, but initial results from small-scale trials are encouraging. The long-term adverse effects cannot yet be accessed. Patients should be selected by an interdisciplinary tumor board. This type of treatment is generally carried out in a specialized center.

Abstract
Purpose To report on the feasibility and performance of conventionally fractionated multileaf collimator (MLC)-based robotic stereotactic body re-irradiation of the head and neck region using MLC-based Cyberknife (CK) technology. Methods Patients treated for recurrent or second primary head and neck cancer (HNC) with curative proton therapy to a target volume > 30 cm3 between 2011 and 2015 were included. MLC-based CK plans were generated using the CK M6 InCise2 MLC system. Dose statistics from MLC-based CK plans were compared to proton beam therapy (PBT) plans according to the following metrics: target coverage, target homogeneity index, gradient index, Paddick conformity index (CI), prescription isodose volume (PIV), treatment time (tTime) for one fraction as well as doses to organs at risk (OAR). Wilcoxon signed-rank test was used to compare dose metrics. Results Eight patients were included; the tumor sites included: salivary glands, pharynx (oropharynx, hypopharynx and retropharynx) and sinonasal cavities. Five of 8 patients were treated with multifield optimisation intensity modulated proton therapy, 3 were treated with passive scattering proton therapy. Median dose was 67 Gy (range 60-70) in 32 fractions (range 30-35). The median high-dose planning target volume (PTV) was 45.4 cm3 (range 2.4 - 130.2 cm3) and the median elective PTV was 91.9 cm3 (range 61.2 - 269.7 cm3). Overall, the mean target coverage (mean 98.3% vs. 96.2% for CK vs. PBT, respectively), maximum dose to PTV (mean 111% vs. 111%, p = 0.2) and mean dose to PTV (mean 104% vs. 104%) were similar across modalities. Highly conformal plans were achieved with both modalities, but mean CI was better with PBT (0.5 vs. 0.6 for CK vs. PBT, p = 0.04). Homogeneity and gradient indexes were similar between the 2 modalities; mean tTime with PBT and CK was 17 vs. 18 min, respectively (p = 0.7). Case-based study revealed that CK and PBT plans allowed for excellent sparing of OAR, with some clinical scenarios associated with better performance of CK while others with better performance of PBT. Conclusion Our study has demonstrated the dosimetric performance of large volume head and neck re-irradiation using MLC-based CK in various clinical scenarios. While conformity was generally better achieved with PBT, MLC-based CK allowed for high dose gradient leading to rapid dose drop-off and sparing of OAR. Conventionally fractionated MLC-based CK could be a competitive alternative in large volume head and neck re-irradiation that deserves further investigation in the clinical setting.

Long-Term Patient-Reported Quality of Life After Stereotactic Body Radiation Therapy for Recurrent, Previously-Irradiated Head and Neck Cancer. Front Oncol 2020; 10:83. [PMID: 32117738 PMCID: PMC7013096 DOI: 10.3389/fonc.2020.00083] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Accepted: 01/16/2020] [Indexed: 11/13/2022] Open
Abstract
Objectives: Long-term quality-of-life data following stereotactic body radiation therapy (SBRT) for recurrent head and neck cancer (rHNC) is underreported. We report patient-reported quality-of-life (PR-QOL) after at least 1 year post-treatment. Methods and Materials: A retrospective review was performed on 64 patients receiving SBRT for previously-irradiated rHNC. PR-QOL was prospectively evaluated using the University of Washington Quality of Life Questionnaire. The mixed effects proportional odds model was used to assess post-treatment overall PR-QOL changes, as well as the effects of late toxicities, tumor volume > 25 cc, local failure, nodal recurrence, distant failure, prior neck dissection, performance status other than ECOG 0 or Karnofsky 100, sex, age >65, squamous vs. non-squamous primary histology, and specific organ recurrence. Results: SBRT had no significant effect on overall PR-QOL at days 1-90 post-treatment (SBRT effect 0.035, p = 0.93) and days 91-365 (SBRT effect -0.30, p = 0.45). Beyond day 365, overall PR-QOL was significantly worse than baseline (SBRT effect -0.77, p =.03). Grade ≥3 late toxicities (p = 0.0072) and tumor volume > 25 cc (p = 0.032) predicted significantly worse overall PR-QOL. Oral cavity recurrence predicted significant decrements in chewing (p = 0.0006), swallowing (p = 0.0301), and taste PR-QOL (p = 0.02). Nasal recurrence predicted significant decrements in taste PR-QOL (p = 0.030). Grade ≥3 late dysphagia predicted significant decline in chewing (p = 0.039) and swallowing (p = 0.0004). Grade ≥3 late osteonecrosis predicted significant differences in pain PR-QOL (p = 0.0026). Conclusion: PR-QOL across several domains declines immediately after SBRT for previously-irradiated rHNC before returning to baseline levels at 1 year. Long-term PR-QOL declines thereafter. Patients with grade ≥3 late toxicities or tumor volume >25 cc report reduced long-term overall PR-QOL, likely representing late disease progression. Specific organ recurrence and grade ≥3 late toxicities predict decrements in specific PR-QOL domains.

[PMID: 31703442 PMCID: PMC6912661 DOI: 10.3390/jcm8111911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 11/05/2019] [Accepted: 11/05/2019] [Indexed: 11/17/2022] Open
Abstract
Neck lymph node (LN) recurrence in the irradiated field represents an important aspect of treatment failure after primary radiotherapy owing to the lack of a standard treatment. The aim of this study is to investigate the efficacy and safety of CyberKnife treatment for neck LN recurrence after radiotherapy. Between 2008 and 2016, 55 neck LN recurrences after radiotherapy in 16 patients were treated with CyberKnife. The median follow-up period was 17 months (range, 2–53 months). The median previous radiotherapy dose was 68 Gy (range, 50–70 Gy). The median marginal dose as equivalent dose delivered in 2-Gy fractions (α/β = 10) was 50 Gy (range, 40–58 Gy). The one-year local control (LC) and overall survival rates were 81% and 71%, respectively. The one-year LC was higher with a target volume ≤1.0 cm3 than that with a target volume >1.0 cm3 (p = 0.006). Fatal bleeding was observed in one patient who had large (91 cm3) and widespread tumor with invasion to the carotid artery before CyberKnife treatment. CyberKnife treatment for neck LN recurrence is safe and feasible in most cases. Indication for the treatment should be carefully considered for large and widespread tumors.

Abstract
Locoregional recurrent/persistent head and neck cancer following primary treatment is a significant challenge as it is usually difficult to treat and has worse outcomes compared to the primary setting. Surgical resection of a local or regional recurrence offers the best chance of cure when feasible. Local recurrence outcomes vary by subsite with laryngeal recurrences having the best prognoses and hypopharynx having the worst. Instances of persistent neck masses following primary nonsurgical treatment can be evaluated with positron emission tomography (PET) with CT (PET-CT) when there is no definitive diagnosis of a recurrence/persistence. Reirradiation with or without chemotherapy can be considered for primary treatment when surgery is not an option, for adjuvant treatment following salvage surgery, or for palliation. Immunotherapy represents a newer class of chemotherapeutic agents. Current guidelines recommend enrollment in clinical trials especially when surgery is not an option as outcomes remain universally poor in the recurrent/persistent setting.

Abstract
BACKGROUND For locally recurrent head and neck cancer, re-irradiation with modern techniques like stereotactic body radiotherapy is a promising, possibly curative alternative to palliative systemic therapy. METHODS We report on 1 patient with nasopharyngeal carcinoma (NPC) and 1 patient with cutaneous squamous cell carcinoma (SCC). Both patients received full dose primary treatment (>66 Gy, EQD2), full dose re-irradiation (>50 Gy, EQD2), and a second course of re-irradiation via robotic radiosurgery (CyberKnife) for a second local recurrence. RESULTS Both treatments resulted in adequate tumor response. No grade III-IV acute or late toxicities occurred. Follow-up at 6 months after third irradiation showed partial remission for the patient with NPC. In the second case (SCC), no toxicities occurred and the tumor was in remission 18 months after last treatment. CONCLUSION These cases show that a second course of re-irradiation utilizing modern techniques like robotic radiosurgery might be feasible for carefully selected patients with head and neck cancer.

Abstract
Objectives To report on overall survival (OS), local control (LC), dose-outcome relationships, and related toxicities following stereotactic body radiation therapy (SBRT) for locally recurrent, previously irradiated squamous cell carcinoma of the head and neck (rSCCHN). Methods We queried the prospectively-maintained RSSearch® Registry for patients with rSCCHN treated with five-fraction SBRT from January 2008 to November 2016. Patients with non-squamous cell histology, missing registry data regarding prior irradiation, those treated with less than five fractions of SBRT, and those treated with SBRT in primary or boost settings were excluded. LC and OS were estimated using the Kaplan-Meier method with comparisons between groups completed using log-rank t-tests and multivariable Cox regression. Logistic regression analyses were used to examine factors predictive of toxicity. Results Forty-five rSCCHN patients treated with SBRT delivered in five fractions at 12 radiotherapy centers were identified. Prescription doses ≥ 40 Gy were associated with higher one-year rates of OS, LC, and a higher likelihood of experiencing toxicities. Acute and late toxicity rates were low (22.2% and 15.6%, respectively) and were all Grade 1-2 with only one late Grade 3 esophagitis. Conclusion Salvage SBRT for rSCCHN resulted in outcomes comparable to prior single-institutional reports in a multi-institutional cohort across clinical settings with low toxicity, thus supporting more widespread adoption of SBRT with recommended doses ≥ 40 Gy.

Abstract
BACKGROUND As high-dose-rate (HDR) brachytherapy can preferentially spare normal anatomic structures surrounding the radiation target, we report on our experience using this technique in head and neck cancer reirradiation. METHODS Twenty patients received HDR brachytherapy reirradiation with curative or palliative intent from 2010-2015. Clinical and toxicity outcomes were recorded. Actuarial outcomes were calculated using Kaplan-Meier analysis. RESULTS For curative treatment, actuarial 2-year rates of local control and overall survival (OS) were 73% and 56%, respectively. Palliatively, a 6-month local control rate of 65% was seen. Age >70 years was associated with poorer OS (P = .042). Prior salvage resection showed a trend toward improved local control and OS (P = .069 and P = .063, respectively). Thirty-three percent had grade 3 to 4 late toxicities. CONCLUSION Curative-intent HDR brachytherapy reirradiation can provide excellent local control and encouraging OS. Given the late toxicity rates, patient selection is essential, with particular utility for younger patients or those treated with salvage resection.

Abstract
BACKGROUND Limited treatment options exist for patients with locoregional recurrences of head and neck squamous cell carcinoma (HNSCC). In the palliative setting, a single session, minimally invasive, and relatively safe therapy is desirable. This case series illustrates the feasibility of a direct intratumoral injection of radioactive holmium-166 microspheres (HoMS) in patients as a palliative treatment for recurrent HNSCC. PATIENTS AND METHODS In this retrospective analysis, patients with already reirradiated irresectable recurrent HNSCC, for whom palliative chemotherapy was unsuccessful or impossible, were offered microbrachytherapy with HoMS. The intratumoral injection was administered manually under ultrasound guidance. Parameters scored were technical feasibility (i.e. administration, leakage, and distribution), clinical response (response evaluation criteria in solid tumors 1.1), and complications (Common Terminology Criteria for Adverse Events 4.3). RESULTS From 2015 to 2017, three patients were treated. None of the patients experienced adverse events; however, therapeutic effects were minimal. Technical difficulties, including precipitating of microspheres and high intratumoral pressure, resulted in suboptimal distribution of the microspheres. CONCLUSION Intratumoral injections with HoMS are minimally invasive and relatively safe in palliation of HNSCC patients. Careful patient selection and improved administration techniques are required to provide a more effective treatment. Further investigation of this novel treatment modality should be carried out because of the absence of side effects and lack of other treatment options.

Abstract
Purpose: Locally recurrent, previously irradiated primary head and neck tumors have historically been associated with poor outcomes. Stereotactic body radiation therapy has emerged as a feasible and promising treatment option for tumor recurrence, particularly in nonsurgical candidates. This study aimed to assess the associated outcomes of stereotactic body radiation therapy used in this setting. Methods: Retrospective analysis of a prospectively collected database of 25 patients treated with CyberKnife for unresectable, recurrent head and neck cancer in a previously irradiated field. The primary end points evaluated were rates of survival, tumor control, and treatment-related toxicities. Results: Median survival of the study population was 7.5 months (range, 1.5-47.0 months). Median survival of the 20 (80%) patients who were treated with curative purpose was 8.3 months. One-year overall survival rate for the entire population was 32%. The respective 1-year and 2-year survival rates for the curative subcohort were 40% and 20%, respectively. Local and locoregional failure occurred in 8 (32%) and 7 (28%) patients, respectively. Low severe acute (4%) and late (6%) treatment-related toxicity rates were observed. No grade 4 or 5 toxicities were observed. Conclusion: Stereotactic body radiation therapy is a viable treatment option for patients with unresectable, recurrent head and neck cancer. Significant tumor control rates are achievable with minimal severe toxicity. Although perhaps associated with patient selection and a heterogeneous sample, overall survival of stereotactic body radiation therapy outcomes appears unfavorable.

Abstract
BACKGROUND The role of adjuvant chemoradiotherapy (CRT) following pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PDA) remains controversial. Recent data suggest that increased margin clearance (MC: distance between tumor and cut surface) is associated with improved survival after PD, but the role of adjuvant CRT in patients with known MC is undefined. We sought to delineate the impact of adjuvant CRT on survival based on MC following PD. METHODS Patients who underwent PD for PDA between 2002 and 2014 were retrospectively stratified into three groups based on MC: 0 mm, ≤1 mm, and >1 mm. The impact of CRT on survival in each MC group was determined by univariate and multivariate analysis. RESULTS Three hundred and ten patients with known MC were analyzed (0 mm =67, ≤1 mm =113, and >1 mm =130). Increasing MC was independently associated with improved OS (≤1 mm, HR 0.66, 95% CI 0.46-0.96, P=0.03; >1 mm, HR 0.51, 95% CI 0.35-0.75, P=0.001; compared to 0 mm). Adjuvant CRT was administered to 62 patients (20%). On margin-stratified multivariate analysis, adjuvant CRT was independently associated with increased OS in patients with ≤1 mm margins (HR 0.36; 95% CI 0.18-0.69, P=0.002) but not for 0 mm and >1 mm margins. CONCLUSIONS This analysis suggests that the benefit of adjuvant CRT may be restricted to patients with ≤1 mm MC after PD for pancreatic cancer.

Abstract
Locoregional failure is the most frequent pattern of failure in locally advanced head and neck cancer patients and it leads to death in most of the patients. Second primary tumors occurring in the other head and neck region reach up to almost 40% of long-term survivors. Recommended and preferred retreatment option in operable patients is salvage surgical resection, reporting a 5-year overall survival of up to 40%. However, because of tumor location, extent, and underlying comorbidities, salvage surgery is often limited and compromised by incomplete resection. Reirradiation with or without combined chemotherapy is an appropriate option for unresectable recurrence. Reirradiation is carefully considered with a case-by-case basis. Reirradiation protocol enrollment is highly encouraged prior to committing patient to an aggressive therapy. Radiation doses greater than 60 Gy are usually recommended for successful salvage. Despite recent technical improvement in intensity-modulated radiotherapy (IMRT), the use of concurrent chemotherapy, and the emergence of molecularly targeted agents, careful patient selection remain as the most paramount factor in reirradiation. Tumors that recur or persist despite aggressive prior chemoradiation therapy imply the presence of chemoradio-resistant clonogens. Treatment protocols that combine novel targeted radiosensitizing agents with conformal high precision radiation are required to overcome the resistance while minimizing toxicity. Recent large number of data showed that IMRT may provide better locoregional control with acceptable acute or chronic morbidities. However, additional prospective studies are required before a definitive conclusion can be drawn on safety and effectiveness of IMRT.

Abstract
Answer questions and earn CME/CNE Laryngeal cancer remains one of the most common tumors of the respiratory tract. Fortunately, significant advancements have been made over the past decade in the treatment of laryngeal cancer. Although surgery has been the historical mainstay for localized disease and still is an integral part of treatment, nonsurgical options like radiation and systemic therapy have emerged as viable options. In addition, in the metastatic setting, novel agents are showing promise for this patient population. The care for patients with laryngeal cancer continues to evolve and truly requires a multidisciplinary team-based approach. Unique morbidities, such as loss of natural voice, respiration, and airway protection during swallowing, are observed with this disease and require special consideration.

Abstract
The management of patients with recurrent head and neck cancers remains a challenging clinical dilemma. Concerns over toxicity with re-irradiation have limited its use in the clinical setting. Stereotactic Body Radiation Therapy (SBRT) has emerged as a highly conformal and precise type of radiotherapy and has the advantage of sparing normal tissue. Although SBRT is an attractive treatment modality, its use in the clinic is limited, given the technically challenging nature of the procedure. In this review, we attempt to provide a comprehensive overview of the role of re-irradiation in patients with recurrent head and neck cancers, with particular attention to the advent of SBRT and its use with systemic therapies such as cetuximab. In the second portion of this review, we present our systematic review of published experiences with SBRT in recurrent head and neck cancers in an attempt to provide data on response rates (RR), overall survival and toxicity. © 2016 Wiley Periodicals, Inc.

High-dose hypofractionated radiotherapy is effective and safe for tumors in the head-and-neck. Oral Oncol 2016; 60:74-80.

Abstract
OBJECTIVES High-dose, hypofractionated radiotherapy (HFRT) is sometimes used to treat malignancy in the head-and-neck (HN), both in the curative and palliative setting. Its safety and efficacy have been reported in small studies and are still controversial. MATERIALS AND METHODS We retrospectively evaluated the outcomes and toxicities of HFRT, including ultra-high-dose fractionation schemes (⩾8Gray per fraction), for HN malignancies. RESULTS A total of 62 sites of measurable gross disease in 48 patients were analyzed. The median follow-up was 54.3months among five survivors and 6.0months in the remaining patients. Median RT dose was 30Gray in 5 fractions; 20/62 lesions (32%) received dose-per-fraction of ⩾8Gray. Overall response rate at first follow-up was 79%. One-year local-progression free rate was 50%. On multivariate analysis for locoregional control, dose-per-fraction ⩾6Gray was associated with control (p=0.04) and previous radiation was associated with inferior control (p=0.04). Patients who achieved complete response to RT had longer survival than those who did not (p=0.01). Increased toxicity rates were not observed among patients treated with dose-per-fraction ⩾8Gray; only re-irradiation increased toxicity rates. CONCLUSION Despite the poor prognostic features noted in this cohort of patients with HN malignancies, HFRT was associated with high response rates, good local control, and acceptable toxicity. Sites that were treated with 6Gray per fraction or higher and had not been previously irradiated had the best disease control. A prospective trial is warranted to further refine the use and indications of HFRT in this setting.

Abstract
Background Treatment of locoregional, recurrent head and neck cancers following definitive radiotherapy has evolved during the past 30 years. Brachytherapy as well as protracted courses of systemic therapy and chemoradiotherapy result in 12-month survival rates of 40% to 50% but have high rates of severe toxicity. Given the advancements in radiotherapy targeting and delivery, stereotactic body radiotherapy (SBRT) has been investigated as an alternative treatment option with the potential advantages of reduced treatment time and rates of toxicity. Methods The authors reviewed prospective trials and retrospective reports from the past decade addressing the management of locoregional, recurrent, previously radiated head and neck cancers, focusing on SBRT. Results The body of evidence is growing in support of reirradiation using SBRT for the treatment of recurrent head and neck cancers. The 1-year survival rates associated with SBRT are promising and similar to those seen with chemotherapy alone and concurrent, conventionally fractionated radiotherapy and chemotherapy. Treatment-related adverse events of reirradiation using SBRT are also similar to other palliative therapies. Late carotid rupture is a relatively rare but concerning late toxicity associated with reirradiation using SBRT. Conclusions SBRT is a promising treatment for locoregional recurrent head and neck cancers. It also offers a logistical advantage over other palliative treatments, as it only requires 1 to 2 weeks of treatment.

Re-irradiation of adenoid cystic carcinoma: analysis and evaluation of outcome in 52 consecutive patients treated with raster-scanned carbon ion therapy. Radiother Oncol 2015; 114:182-8. [PMID: 25640299 DOI: 10.1016/j.radonc.2015.01.002] [Citation(s) in RCA: 49] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2014] [Revised: 12/28/2014] [Accepted: 01/03/2015] [Indexed: 10/24/2022]
Abstract
BACKGROUND Treatment of local relapse in adenoid cystic carcinoma (ACC) following prior radiation remains a challenge: without the possibility of surgical salvage patients face the choice between palliative chemotherapy and re-irradiation. Chemotherapy yields response rates around 30% and application of tumouricidal doses is difficult due to proximity of critical structures. Carbon ion therapy (C12) is a promising method to minimize side-effects and maximize re-treatment dose in this indication. We describe our initial results for re-irradiation in heavily pre-treated ACC patients. METHODS Patients treated with carbon ion therapy between 04/2010 and 05/2013 (N=52pts, median age: 54 a) were retrospectively evaluated regarding toxicity (NCI CTC v.4), tumour response (RECIST) and control rates. 48pts (92.3%) received carbon ions only, 4pts received IMRT plus C12. RESULTS 4pts were treated following R1-resection, 43pts for inoperable local relapse. Most common tumour sites were paranasal sinus (36.5%), parotid (19.2%), and base of skull (17.3%). Pts received a median dose of 51GyE C12/63Gy BED and cumulative dose of 128Gy BED [67-182Gy] after a median RT-interval of 61months. Median target volume was 93ml [9-618ml]. No higher-grade (>°II) acute reactions were observed, 7pts showed blood-brain-barrier changes (°I/II: 8pts; °III: 2pts), 1 pt corneal ulceration, xerophthalmia 7pts, °IV bleeding 1 pt, tissue necrosis 2pts, otherwise no significant late reactions. Objective response rate (CR/PR) was 56.6%. With a median follow-up of 14months [1-39months] local control and distant control at 1a are 70.3% and 72.6% respectively. Of the 18pts with local relapse, 13pts have recurred in-field, 1 pt at the field edge, 3pts out of field, and one in the dose gradient. CONCLUSION Despite high applied doses, C12 re-irradiation shows moderate side-effects, response rates even in these heavily pre-treated patients are encouraging and present a good alternative to palliative chemotherapy. Though most local recurrences occur within the high-dose area, further dose escalation should be viewed with caution.

Abstract
PURPOSE Our aim was to determine the efficacy and quality of life outcomes of head and neck (HN) stereotactic body radiotherapy (SBRT) in a palliative population with significant proportions of de novo HN tumors not amenable to surgery or protracted course of curative radiotherapy (RT). METHODS A retrospective review of a prospective database identified 21 patients with 24 sites that were treated. Patients were treated with intensity modulated RT (IMRT), usually 7-9 static fields with a 2-3-mm margin from gross tumor volume to planning target volume only with no microscopic margin added. Electronic patient records and treatment plans were reviewed. Basic demographic information was collected. The EORTC QLQ-H&N35 questionnaire was the tool used to collect QOL data both pre- and on-treatment fraction 5. Univariate analysis was performed for predictors of local control (LC) and prognostic factors for overall survival (OS). RESULTS A total of 21 patients had 24 sites that were treated. The median age was 87 (range 25-103) and median KPS was 70. The most common histology was squamous cell carcinoma (SCC) 19/24 (79 %), basal cell carcinoma (BCC) 3/24 (16 %), and melanoma (4 %). The median maximal diameter was 3.7 cm (range 1-10 cm). The most commonly treated site was lymph nodes in the neck 13/24 (54 %), skin 8/24 (33 %), 4/24 (16 %) other HN mucosal primary sites. Of the 24 lesions, 17 (71 %) were de novo, without prior treatment and 7/24 (29 %) were recurrent. The most commonly used dose/fraction (fx) was 40 Gy/5 (fx) (range 35/5fx-48/6fx). Of the 24 lesions, 6 (25 %) had complete response, 16/24 (67 %) had partial response, and 2/24 (8 %) had no response. Control was defined as no further progression after treatment. For the entire cohort, LC at 3, 6, and 9 months were 66, 50, and 33 %, respectively. In the de novo group, 2/16 (12.5 %) had local failures with the LC rate of 94, 94, and 87 % at 3 months, 6 months, and 1 year, respectively. In the recurrent group, 4/8 (50 %) had failure with LC rates of 87. 5, 62.5, and 50 % at 3 months, 6 months, and 1 year, respectively. Of the 21 patients, 10 died during follow up, with the OS rate at 3 months, 6 months, and 1 year of 90, 70, and 60 %, respectively. Being defined "de novo" showed a trend toward statistical significance p = 0.046 for local failure. Overall survival did not show significant difference between de novo and recurrent with a p value of 0.267. No significant prognostic variables for OS were found. Pre-treatment QOL scores for the entire cohort were 53/130 versus 38/130 (lower scores indicating better QOL) scores with a trend toward statistical significance p = 0.05. CONCLUSIONS SBRT is efficacious with improved quality of life within this elderly frail population in the treatment of de novo and recurrent tumors of the head and neck with promising quality of life scores.

Abstract
OBJECTIVE Stereotactic body radiotherapy (SBRT) is increasingly used to treat a variety of tumors, including head and neck squamous cell carcinoma (HNSCC) in the recurrent setting. While there are published data for re-irradiation using SBRT for HNSCC, there are limited data supporting its use as upfront treatment for locally advanced disease. STUDY DESIGN/METHODS Here, we describe three patients who received SBRT as the primary treatment for their HNSCC along with a review of the current literature and discussion of future pathways. RESULTS The three cases discussed tolerated treatment well with manageable acute toxicities and had either a clinical or radiographic complete response to therapy. CONCLUSION Head and neck squamous cell carcinoma presents a unique challenge in the elderly, where medical comorbidities make it difficult to tolerate conventional radiation, often given with a systemic sensitizer. For these individuals, providing a shortened course using SBRT may offer an effective alternative.

Abstract
Conventionally fractionated radiotherapy is delivered in 1.8- to 2.0-Gy fractions. With increases in understanding of radiation and tumor biology, various alterations of radiotherapy schedules have been tested in clinical trials and are now regarded by some as standard treatment options. Hyperfractionation is delivered through a greater number of smaller treatment doses. Accelerated fractionation decreases the amount of time over which radiotherapy is delivered typically by increasing the number of treatments per day. Hypofractionation decreases the number of fractions delivered by increasing daily treatment doses. Furthermore, many of these schedules have been tested with concurrent chemotherapy regimens. In this review, we summarize the major clinical studies that have been conducted on altered fractionation in various disease sites.

Abstract
Advances in radiotherapy planning and delivery have been used to treat patients with limited metastatic disease. With these techniques, high rates of treated metastasis control and low toxicity have been reported. Some patients have long disease-free intervals after radiotherapy similar to those seen after surgical resection. Ongoing studies will determine the benefit of these irradiation techniques to treat limited metastases, identify appropriate candidates, and assist in integrating these treatments into management strategies for specific diseases.

Abstract
PURPOSE With a growing elderly population, elderly patients with head and neck cancers represent an increasing challenge with limited prospective data to guide management. The complex interplay between advanced age, associated co-morbidities, and conventional local therapies, such as surgery and external beam radiotherapy ± chemotherapy, can significantly impact elderly patients' quality of life (QoL). Stereotactic body radiotherapy (SBRT) is a well-established curative strategy for medical-inoperable early-stage lung cancers even in elderly populations; however, there is limited data examining SBRT as primary therapy in head and neck cancer. MATERIAL/METHODS Twelve patients with medically inoperable head and neck cancer treated with SBRT ± cetuximab from 2002 to 2013 were retrospectively reviewed. SBRT consisted of primarily 44 Gy in five fractions delivered on alternating days over 1-2 weeks. Concurrent cetuximab was administered at a dose of 400 mg/m(2) on day -7 followed by 250 mg/m(2) on day 0 and +7 in n = 3 (25%). Patient-reported quality of life (PRQoL) was prospectively recorded using the previously validated University of Washington quality of life revised (UW-QoL-R). RESULTS Median clinical follow-up was 6 months (range: 0.5-29 months). The 1-year actuarial local progression-free survival, distant progression-free survival, progression-free survival, and overall survival for definitively treated patients were 69, 100, 69, and 64%, respectively. One patient (8%) experienced acute grade 3 dysphagia and one patient (8%) experienced late grade 3 mucositis; there were no grade 4-5 toxicities. Prospective collection of PRQoL as assessed by UW-QoL-R was preserved across domains. CONCLUSION Stereotactic body radiotherapy shows encouraging survival and relatively low toxicity in elderly patients with unresectable head and neck cancer, which may provide an aggressive potentially curative local therapy while maintaining QoL.

Abstract
BACKGROUND Stereotactic body radiotherapy (SBRT) has been studied in locally recurrent previously-irradiated head and neck cancers; however, the optimum fractionation and patient selection continues to be defined. METHODS Patients (n = 132) with locally recurrent head and neck cancer salvaged via SBRT ± cetuximab (median, 44 Gy/5 fractions) from November 2004 to May 2011 were retrospectively reviewed. Disease outcomes and toxicity were analyzed by predictive factors including treatment duration and tumor volume. RESULTS At a median 6-month follow-up (range, 0-55 months), treatment duration <14 days was associated with significantly improved recurrence-free survival (RFS) at the expense of increased late toxicity (p = .029). Tumor volume >25 cc remained a significant predictor of inferior survival and tumor control, and was associated with significantly more acute toxicity (p = .017) but no difference in late toxicity. CONCLUSION SBRT ± cetuximab achieves promising tumor control and survival with low rates of acute/late toxicity even for recurrences >25 cc. Prolongations in treatment time may decrease late toxicity at the expense of disease control.

Abstract
AIM Review of main SBRT features and indications in primary tumors. BACKGROUND Stereotactic body radiotherapy has been developed in the last few years. SBRT allows the hypofractionated treatment of extra cranial tumors, using either a single or limited number of dose fractions, and resulting in the delivery of a high biological effective dose with low toxicity. MATERIAL AND METHODS SBRT REQUIRES A HIGH LEVEL OF ACCURACY FOR ALL PHASES OF THE TREATMENT PROCESS: effective patient immobilization, precise target localization, highly conformed dosimetry and image guided systems for treatment verification. The implementation of SBRT in routine requires a careful considering of organ motion. Gating and tracking are effective ways to do so, and less invasive technologies "fiducials free" have been developed. Due to the hypofractionated scheme, the physician must pay attention to new dosimetric constraints in organ at risk and new radiobiological models are needed to assess the optimal fractionation and dose schemes. RESULTS Currently, SBRT is safe and effective to treat primary tumors, which are otherwise untreatable with conventional radiotherapy or surgery. SBRT has quickly developed because of its excellent results in terms of tolerance and its high locoregional control rates. SBRT indications in primary tumors, such as lung primary tumors, have become a standard of care for inoperable patients. SBRT seems to be effective in many others indications in curative or palliative intent such as liver primary tumors, and novel indications and strategies are currently emerging in prostate cancer, head and neck tumor recurrences or pelvis reirradiations. CONCLUSION Currently, SBRT is mainly used when there is no other therapeutic alternative for the patient. This is due to the lack of randomized trials in these settings. However, the results shown in retrospective studies let us hope to impose SBRT as a new standard of care for many patients in the next few years.

Abstract
BACKGROUND This study aimed to compare the therapeutic outcomes and fatal carotid blow out syndrome (CBOS) incidence rates between two different stereotactic body radiotherapy (SBRT) protocols. METHODS The study included 75 patients with inoperable locally recurrent head and neck cancer treated with SBRT in our department between June 2007 and March 2011. The first 43 patients were treated sequentially (group I). Then our SBRT protocol was changed due to the high rate of CBOS, and the following 32 patients were treated every other day in a prospective institutional protocol (group II). RESULTS Median overall survival in group I and group II was 11 months and 23 months, respectively (P = 0.006). We observed 11 cases of CBOS. Only 1 of 7 patients (14%) with CBOS survived in group I, whereas 2 of 4 patients (50%) in group II remain alive. CBOS free median overall survivals were 9 months, and 23 months in group I and group II respectively (P = 0.002). The median radiation dose received by the carotid artery in patients with CBOS was 36.5 Gy (range: 34-42.8 Gy), versus 34.7 Gy (range: 0-44 Gy) in the patients that didn't have CBOS (P = 0.15). CBOS did not occur in any of the patients with a maximum carotid artery radiation dose <34 Gy. CONCLUSIONS Every other day SBRT protocol for re-irradiation of recurrent head and neck cancer is promising in terms of decreasing the incidence of fatal CBOS.

Target delineation in stereotactic body radiation therapy for recurrent head and neck cancer: a retrospective analysis of the impact of margins and automated PET-CT segmentation. Radiother Oncol 2013; 106:90-5.

Abstract
BACKGROUND Few guidelines exist on stereotactic body radiation therapy (SBRT) treatment planning for recurrent head and neck cancer. We assessed the impact of retrospectively adding margins/automated PET volumes to the gross tumor volume (GTV) in patients with post-SBRT recurrences. MATERIALS AND METHODS We reviewed 89 patients with recurrent head and neck cancer treated with SBRT using no margin around the GTV. GTVs were recontoured with 1-5mm margins. PET-CT planned GTVs were also recontoured by adding PET-standardized uptake value (SUV)(3.5), SUV(4.5), SUV(40% max), and signal/background ratio (SBR) to the original GTV. We deformably registered recontoured GTVs to post-SBRT scans and assessed fraction of recurrence volume (RV) falling within the GTV, the "RV-GTV overlap." RESULTS With non-PET-CT planning, median RV-GTV overlap increased from 11.7% to 48.2% using 5mm margins, and median GTV size increased by 41.8 cc (156%). With PET-CT planning, RV-GTV overlap increased from 45% to 93.6% using 5mm margins, and GTV size increased by 34.8 cc (140%). Adding SUV(3.5) and SBR increased RV-GTV overlap from 45% to 73.3% and 73.6%, with GTV size increases of 0.8 (3%) and 3.1 cc (11%), respectively. CONCLUSIONS Recontouring increased recurrence coverage and also GTV size. Margins up to 5mm may reduce failures but could possibly increase toxicities. Automated PET contours may reduce near-miss failures with smaller increases in GTV size.

Abstract
Stereotactic Body Radiotherapy (SBRT) is increasingly used to treat a variety of head and neck tumors as a result of its highly conformal dose distributions and stereotactic spatial accuracy in delivery. Our experience and other previous reports have shown that SBRT is technically feasible, well-tolerated and compares favorably to other alternatives of salvage therapy in the management of patients with recurrent and/or previously irradiated head and neck cancers. Furthermore, it has the advantage of a shorter treatment schedule, greater compliance, and safe delivery in the outpatient setting. This affords an opportunity to introduce SBRT as a definitive treatment in select patients. This review presents an overview of the use of SBRT for managing head and neck tumors by highlighting the existing indications and the expanding role of SBRT in managing these patients.

Abstract
Answer questions and earn CME/CNE Oral complications resulting from cancer and cancer therapies cause acute and late toxicities that may be underreported, underrecognized, and undertreated. Recent advances in cancer treatment have led to changes in the incidence, nature, and severity of oral complications. As the number of survivors increases, it is becoming increasingly recognized that the aggressive management of oral toxicities is needed to ensure optimal long-term oral health and general well-being. Advances in care have had an impact on previously recognized oral complications and are leading to newly recognized adverse effects. Here, the authors briefly review advances in cancer therapy, including recent advances in surgery, oral care, radiation therapy, hematopoietic cell transplantation, and medical oncology; describe how these advances affect oral health; and discuss the frequent and/or severe oral health complications associated with cancer and cancer treatment and their effect upon long-term health. Although some of the acute oral toxicities of cancer therapies may be reduced, they remain essentially unavoidable. The significant impact of long-term complications requires increased awareness and recognition to promote prevention and appropriate intervention. It is therefore important for the primary oncologist to be aware of these complications so that appropriate measures can be implemented in a timely manner. Prevention and management is best provided via multidisciplinary health care teams, which must be integrated and communicate effectively in order to provide the best patient care in a coordinated manner at the appropriate time.

Abstract
PURPOSE The aim of this study was to evaluate the role of stereotactic body radiotherapy (SBRT) as adjuvant therapy for resected pancreatic adenocarcinoma with close or positive margins. METHODS Between September 2006 and January 2010, 24 patients were treated with adjuvant SBRT following surgical resection. Eight (33.3%) patients had close margins of 1-2.5 mm to the retroperitoneal, vascular structures, and periduodenal adipose tissue. Sixteen (66.7%) patients had positive margins at retroperitoneal margin and vascular structures. Twenty-three patients received 24 Gy (20-24 Gy) in one fraction, and one had 30 Gy in three fractions. The median target volume was 11 cc (4.5-30 cc). Eighteen patients were treated with the Cyberknife® Robotic Radiosurgery System and six patients were treated with Trilogy™ intensity-modulated radiosurgery. Kaplan-Meier survival analyses were used to estimate freedom-from-local-progression (FFLP), and overall survival (OS) rates. PET/CT or CT was used to monitor disease recurrence following SBRT. RESULTS The median follow-up for all patients was 12.5 months (1.4-39.5 months), and among surviving patients it was 16.3 months (2-39.5 months). The FFLP rates at 6 months, 1 and 2 years were 94.7%, 66%, and 44%, respectively. Overall, FFLP was achieved in seven (87.5%) patients with close margins, and 10 (62.5%) with positive margins. After SBRT, 19 patients resumed or started a 6-month course of gemcitabine-based chemotherapy at a median interval of 18 days (range, 9-31 days) post-SBRT. The median OS was 26.7 months and the 1- and 2-year OS rates were 80.4% and 57.2%, respectively. Of the 24 patients, 12 (50%) developed distant metastases of whom two (25%) had close margins and 10 (62.5%) had positive margins. Ten patients (41.7%) were free of progression at last follow-up (range, 3-39.5 months). Three patients (12.5%) had grade 1-2 acute GI toxicities, and two patients (8.3%) had grade 1 and 2 late toxicities. No patients experienced grade 3 or 4 toxicity, including bowel perforation, secondary to SBRT. CONCLUSIONS Our data suggest that adjuvant SBRT for resected pancreatic cancer can be achieved with minimal toxicity. This shorter treatment course allowed initiation of systemic chemotherapy shortly after the completion of SBRT.

Prospective evaluation of patient-reported quality-of-life outcomes following SBRT ± cetuximab for locally-recurrent, previously-irradiated head and neck cancer. Radiother Oncol 2012; 104:91-5.

Abstract
PURPOSE Stereotactic body radiotherapy (SBRT) has emerged as a promising salvage strategy for unresectable, previously-irradiated recurrent squamous cell carcinomas of the head and neck (rSCCHN). Here-in, we report the first prospective evaluation of patient-reported quality-of-life (PR-QoL) following re-irradiation with SBRT±cetuximab for rSCCHN. MATERIALS AND METHODS From November 2004 to May 2011, 150 patients with unresectable, rSCCHN in a previously-irradiated field receiving >40 Gy were treated with SBRT to 40-50 Gy in 5 fractions ± concurrent cetuximab. PR-QoL was prospectively acquired using the University of Washington Quality-of-Life Revised (UW-QoL-R). RESULTS Overall PR-QoL, health-related PR-QoL, and select domains commonly affected by re-irradiation progressively increase following an initial 1-month decline with statistically significant improvements noted in swallowing (p=0.025), speech (p=0.017), saliva (p=0.041), activity (p=0.032) and recreation (p=0.039). CONCLUSIONS Especially for patients surviving >1-year, improved tumor control associated with SBRT re-irradiation may ameliorate decreased PR-QoL resulting from rSCCHN. These improvements in PR-QoL transcend all measured domains in a validated PR-QoL assessment tool independent of age, use of cetuximab, tumor volume, and interval since prior irradiation.

Abstract
PURPOSE To assess the clinical outcomes of single or oligo-fractionated stereotactic radiotherapy (SRT) using dynamic conformal arcs (DCA) for head and neck tumors (HNTs). METHODS Thirty-four consecutive patients with 35 lesions treated between 2005 and 2009 were retrospectively evaluated, of whom 85.7 % had recurrent or metastatic disease, and 45.7 and 34.3 % had previous radiotherapy and surgery, respectively. The median SRT dose was 22.3 Gy (11.2-32.8) in 2-4 fractions with a median interval of 7 days and 10.4 Gy (9.2-12.4) in one fraction. SRT was combined with upfront conventionally fractionated RT in 48.6 % of patients. RESULTS The median follow-up periods were 18.4 months (2-84.1) for the entire cohort and 49.6 months for the survivors. The 1- and 2-year local control (LC) rates were 84.3 and 70.5 %, with the 1- and 2-year overall survival (OS) rates of 78.6 and 51.6 %. LC was significantly better for tumor volumes <25.6 cm(3) (p = 0.001). OS was significantly longer in patients without any disease outside the SRT site (p < 0.001), whereas LC after the SRT did not affect the OS. Late adverse events occurred in 9 patients, including cranial nerve (CN) injury (grade 3/4) in 2, brain radionecrosis in 5 (grade 1), and fatal bleeding in 2 patients harboring uncontrolled lesions abutting the carotid artery. CONCLUSIONS DCA-based SRT can confer relatively long-term LC with acceptable toxicity in selected patients with HNTs. The patients with CN involvement or tumor volume ≥25.6 cm(3) were deemed unsuitable for this treatment regimen.
