Stereotactic body radiotherapy optimization to reduce the risk of carotid blowout syndrome using normal tissue complication probability objectives. J Appl Clin Med Phys 2022; 23:e13563. [PMID: 35194924 PMCID: PMC9121056 DOI: 10.1002/acm2.13563] [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: 09/15/2021] [Revised: 01/14/2022] [Accepted: 02/02/2022] [Indexed: 12/24/2022] Open
Abstract
Purpose To determine the possibility of further improving clinical stereotactic body radiotherapy (SBRT) plans using normal tissue complication probability (NTCP) objectives in order to minimize the risk for carotid blowout syndrome (CBOS). Methods 10 patients with inoperable locally recurrent head and neck cancer, who underwent SBRT using CyberKnife were analyzed. For each patient, three treatment plans were examined: (1) cone‐based without delineation of the ipsilateral internal carotid (clinical plan used to treat the patients); (2) cone‐based with the carotid retrospectively delineated and spared; and (3) Iris‐based with carotid sparing. The dose–volume histograms of the target and primary organs at risk were calculated. The three sets of plans were compared based on dosimetric and TCP/NTCP (tumor control and normal tissue complication probabilities) metrics. For the NTCP values of carotid, the relative seriality model was used with the following parameters: D50 = 40 Gy, γ = 0.75, and s = 1.0. Results Across the 10 patient plans, the average TCP did not significantly change when the plans were re‐optimized to spare the carotid. The estimated risk of CBOS was significantly decreased in the re‐optimized plans, by 14.9% ± 7.4% for the cone‐based plans and 17.7% ± 7.1% for the iris‐based plans (p = 0.002 for both). The iris‐based plans had significant (p = 0.02) reduced CBOS risk and delivery time (20.1% ± 7.4% time reduction, p = 0.002) compared to the cone‐based plans. Conclusion A significant improvement in the quality of the clinical plans could be achieved through the delineation of the internal carotids and the use of more modern treatment delivery modalities. In this way, for the same target coverage, a significant reduction in the risk of CBOS could be achieved. The range of risk reduction varied depending on the proximity of carotid artery to the target.

Abstract
BACKGROUND In head and neck cancer, distant metastases may be present at diagnosis (M1) or occur after treatment (DM). It is unknown whether M1 and DM follow the same clinical development and share prognosis, as population-based studies regarding outcomes are scarce. Therefore, we investigated the incidence, location of metastases and overall survival of patients with M1 and DM. MATERIALS AND METHODS Patients diagnosed with squamous cell carcinoma of the pharynx and larynx in Denmark 2008-2017 were identified in the Danish Head and Neck Cancer Group (DAHANCA) database. We identified 7300 patients, of whom 197 (3%) had M1 and 498 (8%) developed DM during follow-up. RESULTS The 5-year cumulative incidence of DM was 8%. 1- and 2-year overall survival for DM (27% and 13%) vs. M1 (28% and 9%) were equally poor. There was no significant difference in location of metastases for M1 and DM and the most frequently involved organs were lungs, bone, lymph nodes and liver, in descending order. In oropharyngeal squamous cell carcinomas, the location of metastases did not differ by p16-status. For p16-positive patients, 21% of DM occurred later than three years of follow-up compared to 7% of p16-negative patients. CONCLUSION Incidence, location of metastases and prognosis of primary metastatic (M1) or post-treatment metastatic (DM) disease in pharyngeal and laryngeal squamous cell carcinoma are similar in this register-based study.

Conventionally fractionated large volume head and neck re-irradiation using multileaf collimator-based robotic technique: A feasibility study. Clin Transl Radiat Oncol 2020; 24:102-110. [PMID: 32715109 PMCID: PMC7372092 DOI: 10.1016/j.ctro.2020.06.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 06/22/2020] [Accepted: 06/28/2020] [Indexed: 11/23/2022] Open
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.

Abstract
Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

Abstract
Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal.

Abstract
After a local and/or regional recurrence of head and neck squamous cell carcinoma (HNSCC) not all patients are candidates to salvage treatment. The objective of this study was to identify the variables related to performance of salvage surgery with curative intent in these patients. We performed a retrospective study of 1088 HNSCC patients with a local and/or regional recurrence. According to a multivariate analysis, the variables related to performance of salvage surgery were the Karnofsky index, the location and extension of the primary tumor, the initial treatment, the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence, and the year the recurrence was diagnosed. Considering salvage surgery as the dependent variable, the results of a recursive partitioning analysis defined four categories of patients in function of the category of local and regional extension of the initial tumor, the location of the primary tumor, the initial treatment and the disease-free interval between treatment of the initial tumor and diagnosis of the recurrence.

Abstract
OBJECTIVE To estimate selective neck irradiation omitting surgical Sublevel IIb. METHODS Bilateral necks of 47 patients (94 necks) were subjected to definitive radiotherapy for supraglottic cancer. Sixty-nine and 25 necks were clinically node negative (cN-) and clinically node positive (cN+), respectively. We subdivided Sublevel IIb by the international consensus guideline for radiotherapy into Sublevel IIb/a, directly posterior to the internal jugular vein, and Sublevel IIb/b, which was behind Sublevel IIb/a and coincided with surgical Sublevel IIb. Bilateral (Sub)levels IIa, III, IV and IIb/a were routinely irradiated, whereas Sublevel IIb/b was omitted from the elective clinical target volume in 73/94 treated necks (78%). RESULTS Two patients presented with ipsilateral Sublevel IIb/a metastases. No Sublevel IIb/b metastasis was observed. Five patients experienced cervical lymph node recurrence; Sublevel IIb/a recurrence developed in two patients, whereas no Sublevel IIb/b recurrence occurred even in the cN- necks of cN+ patients or cN0 patients. The 5-year regional control rates were 91.5% for Sublevel IIb/b-omitted patients and 77.8% for Sublevel IIb/b treated patients. CONCLUSIONS Selective neck irradiation omitting Sublevel IIb/b did not compromise regional control and could be indicated for cN- neck of supraglottic cancer.

A simple strategy to decrease fatal carotid blowout syndrome after stereotactic body reirradiaton for recurrent head and neck cancers. Radiat Oncol 2013; 8:242. [PMID: 24139288 PMCID: PMC4016484 DOI: 10.1186/1748-717x-8-242] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2013] [Accepted: 10/15/2013] [Indexed: 11/10/2022] Open
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.

Abstract
The principles of open versus laser microsurgical approaches for partial resections of the larynx are described, oncologic as well as functional results discussed and corresponding outcomes following primary radiotherapy are opposed. Over the last decade, the endoscopic partial resection of the larynx has developed to an accepted approach in the treatment of early glottic and supraglottic carcinomas thus leading to a remarkable decline in the use of open surgery. Comparing the various surgical approaches of laryngeal partial resections, the oncological outcome of the patients, as far as survival and organ preservation are concerned, are comparable, whereas functional results of the endoscopic procedures are superior with less morbidity. The surgical procedures put together, are all superior to radiotherapy concerning organ preservation. Transoral laser microsurgery has been used successfully for vocal cord carcinomas with impaired mobility or fixation of the vocal cord, supraglottic carcinomas with infiltration of the pre- and/or paraglottic space as well as for selected hypopharyngeal carcinomas. It has been well documented that laser microsurgery achieves good oncological as well as functional results with reasonable morbidity. However, patients with those tumours have been successfully treated by open partial resections of the larynx at medical centres with appropriate expertise. The initially enthusiastic assessment of study results concerning the efficacy of various protocols of chemoradiation with the intent of organ preservation for laryngeal and hypopharyngeal carcinomas are judged more cautious, today, due to recent reports of rather high rates of late toxicity complications.

Abstract
Treatment options for laryngeal carcinoma, one of the most common head and neck malignancies, consist of radiotherapy, surgery, chemotherapy or a combination thereof. The functional treatment of laryngeal carcinoma poses a considerable challenge because of its resistance to chemotherapy and radiotherapy, and its tendency for local recurrence. Finding ways to inhibit the energy supply of malignant tumours is becoming an increasingly attractive proposition. Glucose transporter-1 (Glut-1; encoded by the SLC2A1 gene in humans) is the main transporter of glucose in solid carcinomas and has become a focus of cancer research. Recently, it was shown that the increased expression of SLC2A1 in head and neck carcinomas is correlated with lymph node metastasis, poor survival and clinical stage, and revealed that the suppression of SLC2A1 expression by antisense oligodeoxynucleotides decreased glucose uptake and inhibited the proliferation of Hep-2 cells. Thus, the authors propose the suppression of SLC2A1 expression as a new therapeutic target for laryngeal carcinoma.

Abstract
Current practice standards for the treatment of early to moderately advanced laryngeal and hypopharyngeal cancer demand both achievement of cure and preservation of laryngeal structure and function to the greatest extent possible. The oncologic and functional results of transoral laser microsurgery (TLM) for early glottic cancer appear to be comparable to those of radiotherapy, with a higher rate of laryngeal preservation and a lower cost. TLM for early and moderately advanced supraglottic and hypopharyngeal cancers offers similar results with regard to survival and local control to those obtained with open surgical approaches. In addition, functional results of TLM are superior to those of open approaches because tracheotomies are usually avoided, rehabilitation of swallowing is faster, and hospital stay is shorter. TLM, when applicable, has become the preferred modality for surgical treatment of most early to moderately advanced cancers of the larynx and selected tumors of the hypopharynx.

Abstract
PURPOSE In this study, we present our results of reirradiation of locally recurrent head-and-neck cancer with image-guided, fractionated, frameless stereotactic body radiotherapy technique. METHODS AND MATERIALS From July 2007 to February 2009, 46 patients were treated using the CyberKnife (Accuray, Sunnyvale, CA) at the Department of Radiation Oncology, Hacettepe University, Ankara, Turkey. All patients had recurrent, unresectable, and previously irradiated head-and-neck cancer. The most prominent site was the nasopharynx (32.6%), and the most common histopathology was epidermoid carcinoma. The planning target volume was defined as the gross tumor volume identified on magnetic resonance imaging and computed tomography. There were 22 female and 24 male patients. Median age was 53 years (range, 19-87 years). The median tumor dose with stereotactic body radiotherapy was 30 Gy (range, 18-35 Gy) in a median of five (range, one to five) fractions. RESULTS Of 37 patients whose response to therapy was evaluated, 10 patients (27%) had complete tumor regression, 11 (29.8%) had partial response, and 10 (27%) had stable disease. Ultimate local disease control was achieved in 31 patients (83.8%). The overall survival was 11.93 months in median (ranged, 11.4-17.4 months), and the median progression free survival was 10.5 months. One-year progression-free survival and overall survival were 41% and 46%, respectively. Grade II or greater long-term complications were observed in 6 (13.3%) patients. On follow-up, 8 (17.3%) patients had carotid blow-out syndrome, and 7 (15.2%) patients died of bleeding from carotid arteries. We discovered that this fatal syndrome occurred only in patients with tumor surrounding carotid arteries and carotid arteries receiving all prescribed dose. CONCLUSIONS Stereotactic body radiotherapy is an appealing treatment option for patients with recurrent head-and-neck cancer previously treated with radiation to high doses. Good local control with considerable 1-year survival is achieved with a relatively high rate of morbidity and related mortality.

Abstract
OBJECTIVE The purpose of this retrospective study was to analyze the results of accelerated hyperfractionation for patients with moderately advanced (T2 and T3) laryngeal cancer. METHODS Between 1998 and 2007, 9 supraglottic carcinomas (6 T2N0M0, 2 T2N2M0, 1 T3N0M0), 30 glottic carcinomas (25 T2N0M0, 5 T3N0M0), and 1 T2N0M0 subglottic carcinoma were treated with definitive radiotherapy using accelerated hyperfractionation without concurrent chemotherapy. The dose-fractionation for 35 patients was 72.8 Gy/56 fractions/5.6 weeks, and that for four patients treated between 1998 and 2001 was 72 Gy/60 fractions/6 weeks. One patient who had been treated with steroid therapy for systemic lupus erythematosus was treated by 67.8 Gy/44 fractions/4.4 weeks. RESULTS The local control and overall survival probabilities at 5 years for supraglottic carcinomas were 75% and 86%, respectively. Those for glottic carcinomas were 80% and 92%, respectively. The 5-year local control probabilities for T2 and T3 tumors were 85% and 56%, respectively. This excellent local control rate especially for T2 laryngeal carcinomas may be attributable to the effect of accelerated hyperfractionation. No late toxicities of grade 2 or more was noted among the 39 patients treated with 72.8 Gy/56 fractions or 72 Gy/60 fractions. CONCLUSION Accelerated hyperfractionation of 72.8 Gy/56 fractions/5.6 weeks using 1.3 Gy/fraction seems a safe and effective dose-fractionation for patients with moderately advanced laryngeal carcinomas.

Abstract
PURPOSE Epiglottic (epilaryngeal) carcinoma has been treated conventionally by radical external beam radiotherapy or partial laryngectomy. The aim of this study is to evaluate the role of brachytherapy boost as a novel approach for lingual epiglottic lesions. METHODS AND MATERIALS Twenty-three patients with T(2-3)N(0-1) lingual epiglottic carcinoma (SCC) were treated with curative intent between January 1990 and December 2001 using low dose rate interstitial (192)Ir implant boost, moderate dose of 25Gy at 0.5cm (mean dose rate, 50.5 cGy/h) 3 weeks after moderate dose of external beam radiotherapy (mEBRT) of 46Gy/23#/28-31d. RESULTS Complete response after mEBRT was observed in 18 of the 23 patients (78%) and partial response was seen in 5 of the 23 patients (22%). After implant, all patients had complete response. Locoregional control was seen in 19 of the 23 patients (82.6%). Two patients developed distant metastases. Disease-free survival and overall survival at 5 years were 68.3% and 66.7%, respectively. Disease-free survival at 5 years showed a trend toward better outcome for biologically equivalent doses >85Gy compared with biologically equivalent doses <85Gy (80% vs. 68%) (p=0.18). All patients had minimal to acceptable xerostomia. CONCLUSIONS Interstitial boost with mEBRT is feasible, effective, and a novel approach for lingual epiglottic lesions.

Abstract
BACKGROUND All patients treated for laryngeal cancer are offered the same follow-up schedule to detect asymptomatic locoregional recurrences. In this study, we evaluated the prognostic profile of patients for cancer recurrence and estimated the lead time. METHODS A cohort study was performed between 1990 and 1995. Cox proportional hazards model was used to analyze the prognostic factors. The effect of altering the follow-up for asymptomatic recurrence detection was determined after estimating the lead time. RESULTS The variables cT classification, smoking, and histologic grade proved to be prognostic factors. The risk of locoregional failure was 15% in the low-risk group versus 29% in the high-risk group. The estimated lead time was 2 to 4 weeks. CONCLUSION Risk profiles for locoregional relapse were defined. Intensifying the follow-up schedule is not advisable because the lead time is very short. An excessively high number of routine visits would have to be performed to increase the detection rate for asymptomatic recurrences.

Abstract
BACKGROUND The role of interstitial brachytherapy (IBT) in the salvage surgical management of regional lymphatic metastases for head and neck cancer has not been defined to date. To further explore its therapeutic benefit in the management of head and neck squamous cell carcinoma, the authors reviewed their experience utilizing IBT at the M. D. Anderson Cancer Center. METHODS A retrospective chart review of all patients who were received IBT for cervical recurrences of head and neck cancer was undertaken. Twenty-two patients were identified; all patients underwent neck dissection and intraoperative placement of afterloading catheters as part of the salvage treatment. Soft tissue reconstruction was performed when necessary. The duration and dosage of salvage brachytherapy was reviewed, and the overall disease-free survival rates were determined. RESULTS All patients had been treated with external beam radiation therapy prior to recurrence, with an average dose of 65 grays (Gy), and 46% of patients had undergone prior neck dissection. The median time to regional recurrence after definitive treatment was 30 months. Soft tissue coverage of the surgical bed with a muscle flap, most commonly a pectoralis major flap, was performed in 19 of 22 patients. The median IBT dose was 60 Gy over a total duration of 4 days. Postoperative complications were few, and there were no perioperative deaths. Recurrences in the reirradiated necks occurred in 27% of patients. CONCLUSIONS Regional recurrences are common after multimodality treatment for head and neck cancer and are challenging to manage. Although its role has not been defined clearly, salvage neck dissection with IBT is beneficial in the management of recurrent lymphatic metastases of upper aerodigestive tract carcinomas.

Abstract
INTRODUCTION Horizontal supraglottic laryngectomy (HSL) allows the preservation of a functioning larynx and avoids a permanent tracheostoma. Its use and training have been conditioned by the employment of organ preservation programs and endoscopic laser surgery. OBJECTIVE To show functional and oncological long-term results of HSL. MATERIAL AND METHOD 110 patients treated with HSL with a minimum of 5 years follow-up. RESULTS Local control, 89% for T1, 91% for T2, 80% for T3 and 91% for T4. Regional control 80.9%. Cause specific survival, 77.6%, 72.6% and 67% at 3, 5 and 10 years, significantly influenced by N-stage. Functional larynx preservation, 87%, with a 8.5% of non-decanulated patients. CONCLUSION HSL is a safe surgical procedure, with similar functional and oncological results to other therapeutic options. Its indications should be considered according to own experience and results.

Abstract
BACKGROUND The literature is scarce regarding the use of interstitial high-dose-rate brachytherapy (I-HDR) as adjuvant treatment of the cervical region, and most reports are focused on primary tumors of the mobile tongue and oropharynx. We evaluated the outcome and morbidity related to an institutional treatment policy, using I-HDR as the sole adjuvant treatment or in combination with external beam radiotherapy (EBRT) at the Departments of Radiation Oncology and Head and Neck Surgery, Hospital do Cancer, Sao Paulo, Brazil. METHODS From October 1994 to December 2003, charts of 42 patients who had biopsy-proven cervical head and neck cancer, with a median follow-up of 36 months (range, 8-111 months), were reviewed. The median age of the patients was 55 years (range, 31-76 years), and the male/female ratio was 4.25:1.00. Thirty-five patients had previous irradiation with EBRT, with doses ranging from 30 Gy to 65 Gy (median, 52 Gy). The total dose of I-HDR ranged from 12 Gy to 48 Gy (median, 24 Gy), given in three to 14 fractions (median, 6 fractions) in 2 to 8 days (median, 4 days). RESULTS The total treatment time ranged from 19 to 83 days (median, 35 days). The 5- and 8-year overall survival (OS) rates were 52.5% and 48.1%, respectively; and the relapse-free survival (RFS) rates were 48.5% and 38.1%, respectively. The only statistically significant prognostic factor for RFS and OS at 5 and 8 years was margin status (p = .0050). Four patients (9.5%) had late adverse side effects, such as local dehiscence (n = 2), local ulcer (n = 1), and extensive neck fibrosis (n = 1), not related to a higher dose to the skin or graft. CONCLUSION These results suggest that I-HDR can be recommended in selected patients with first presentation lesions, local recurrences, or second primary carcinomas, even with a previous course of EBRT, but further studies are eagerly awaited to delineate the optimum schedule for this combination-treatment modality.

Abstract
Early stage laryngeal cancer can be effectively cured by radiotherapy or conservative laryngeal surgery. In the UK, radiotherapy is the preferred first line treatment. However, up to 25% of patients with T2 tumours will demonstrate locally persistent or recurrent disease at the original site, requiring salvage surgery to achieve a definitive cure. Patients experiencing treatment failure have a relatively poor prognosis. A retrospective analysis was conducted consisting of 124 patients with early stage (T1–T2, N0) laryngeal squamous cell carcinoma. In total, 62 patients who failed radiotherapy were matched for T stage, laryngeal subsite and smoking history to a group of 62 patients successfully cured by radiotherapy. Using immunohistochemistry the groups were compared for expression of apoptotic proteins: bcl-2, bcl-XL, bax, bak and survivin. Radioresistant laryngeal cancer was associated with bcl-2 (P<0.001) and bcl-XL (P=0.005) expression and loss of bax expression (P=0.012) in pretreatment biopsies. Bcl-2 has an accuracy of 71% in predicting radiotherapy outcome. The association between expression of bcl-2, bcl-XL and bax with radioresistant cancer suggests a potential mechanism by which cancer cells avoid the destructive effects of radiotherapy. Predicting radioresistance, using bcl-2, would allow the clinician to recommend conservative laryngeal surgery as an alternative first line treatment to radiotherapy.

Abstract
PURPOSE The supraglottic larynx has rich lymphatic drainage, resulting in a high incidence of occult cervical metastases, and the optimal treatment of the clinically uninvolved neck in supraglottic laryngeal cancer remains controversial. Selected retrospective series report a greater than 20% regional failure after treatment by radiotherapy alone, and some investigators recommend routine prophylactic neck dissection. We report on our series of patients who received radiotherapy as sole treatment to the clinically negative neck, either to the bilateral neck for N0 disease or to the contralateral neck for ipsilateral lymphatic involvement. PATIENTS AND METHODS Between 1971 and 1998, 150 patients with supraglottic laryngeal cancer received radiotherapy alone to the clinically negative neck. Fifty-two patients had ipsilateral lymph node metastases (N1 = 16, N2a = 12, N2b = 20, N3 = 4), and 98 patients had no clinical nodal involvement. The primary site (T1/T2 = 74, T3/T4 = 76) was treated with radiotherapy (N = 91) or laryngectomy plus radiotherapy (N = 59). Neck dissection was performed on the involved neck in 36/52 node-positive patients for either multiple involved nodes (N = 20) or size > 3 cm (N = 16). Radiotherapy was delivered in standard fractionation and field arrangement. The median dose to the clinically negative neck was 5000 cGy (range: 4860-6000 cGy). RESULTS With a median follow-up of 48 months, the clinically negative neck was the first site of failure in 3.3% of patients. The contralateral neck remained disease free in all patients. Five failures occurred in the N0 neck, and the median time to recurrence was 12 months (range: 5-30 months). Salvage therapy was neck dissection for the N0 neck failures. The 5-year locoregional control, disease-specific survival, and overall survival were 69%, 74%, and 61%, respectively. DISCUSSION Our data support the use of radiotherapy as a prophylactic treatment for the clinically negative neck. Tumor control in the clinically uninvolved cervical lymphatics is comparable to that in surgical series, suggesting that routine neck dissection may not be necessary. Prospective trials are necessary to further define the role of radiotherapy in this patient population.

Abstract
Survival rates for head and neck cancer are comparatively poor, typically 40% at 5 years. Radiotherapy is one of the most common modalities used to cure early-stage cancers. It has the advantage in that it preserves anatomical structure and function. However, treatment failures do occur necessitating salvage surgery if a cure is to be achieved. A universally accepted definition of radioresistant cancer does not exist. Second primaries and occult metastasis are common in head and neck cancer, and can be confused with true radioresistant tumours. We suggest a strict definition for radioresistant laryngeal cancer and characterize 66 radioresistant tumours stage matched to 66 radiosensitive tumours. It was not possible to differentiate the radioresistant group from the radiosensitive groups using tumour differentiation. By using an agreed set of criteria defining radioresistant head and neck tumours, researchers will be better able to investigate molecular and cellular markers of radioresistance.

Pilot study of postoperative reirradiation, chemotherapy, and amifostine after surgical salvage for recurrent head-and-neck cancer. Int J Radiat Oncol Biol Phys 2004; 59:72-7.

Abstract
PURPOSE Salvage surgery alone after radiotherapy (RT) failure for locally advanced head-and-neck cancer is frequently unsuccessful because of subsequent recurrence. We designed a prospective protocol to determine the feasibility, toxicity, and preliminary efficacy of a regimen of postoperative reirradiation, chemotherapy and the radioprotector amifostine after salvage head-and-neck surgery. METHODS AND MATERIALS Eligible patients had biopsy-proven locally advanced, but resectable, recurrence without distant metastases >6 months after previous RT. After adequate healing from surgery, patients underwent RT to 54-66 Gy within 5-5.5 weeks to the resection bed (lifetime RT dose, 100-130 Gy). The fractionation was 1.5 Gy b.i.d. within 2 weeks, followed by a 1-week break, followed by 1.5 Gy b.i.d. to a total of 54-66 Gy. Chemotherapy consisted of cisplatin 25 mg/m(2)/d three times and 5-fluorouracil 500 mg/m(2)/d continuous infusion for 4 days, for two cycles (Weeks 1 and 5). Amifostine (500 mg i.v.) was administered daily, 30 min before either the morning or the afternoon RT. RESULTS Between 1998 and 2001, 16 patients were enrolled and studied. Two patients had gross residual disease after surgery; all other patients underwent complete surgical resection but had high-risk features (rT3-T4 and/or N+ disease). Three patients (19%) had serious acute toxicity events (nonneutropenic infections) that were reversible. The median follow-up was 35 months. The actuarial locoregional control rate was 81% at 3 years. Three patients developed isolated distant metastases and one developed a fatal second primary cancer (hepatoma). The 2- and 3-year actuarial event-free survival rate was 81% and 50%, respectively. The 2- and 3-year actuarial overall survival rate was 81% and 63%, respectively. Both patients who had gross residual disease after surgery had early recurrence; if these patients were excluded from analysis, the 3-year actuarial survival and event-free survival rate was 67% and 59%, respectively. Of the 16 patients, 6 (38%) developed Grade 3+ late toxicity, including one fatal stroke and two life-threatening major vessel necrosis and/or bleeding events. CONCLUSION This regimen of postoperative reirradiation/chemotherapy plus amifostine is feasible and was well tolerated acutely, with encouraging oncologic efficacy. However, the incidence and severity of late effects was significant and suggests that modifications are necessary for future studies in this patient population.

Abstract
Early stage squamous cell carcinoma of the larynx can be effectively cured by radiotherapy. Unfortunately treatment failures do occur and at present cannot be predicted by the clinician. This article reviews the potential molecular and cellular markers that may help to predict radioresistance in early stage laryngeal cancer.
