Abstract
BACKGROUND Maxillary sinus squamous cell carcinoma (MS-SCC) is an infrequent malignancy, and determining the optimal neck management for patients with cT3/4N0 MS-SCC remains a topic of ongoing debate. The purpose of this study was to compare the prognoses and quality of life outcomes of patients who underwent either elective neck dissection (END) or elective neck irradiation (ENI) for cT3/4N0 MS-SCC. METHODS In this retrospective study, we enrolled patients with surgically treated cT3/4N0 MS-SCC, and the impact of different neck management strategies on regional control and disease-specific survival was compared using propensity score matching. The effect of surgical intervention on quality of life was evaluated using the Mann-Whitney U test. RESULTS Of the 120 patients included, 36 underwent END. After propensity score matching, our analysis indicated that END did not lead to superior outcomes than ENI, as demonstrated by comparable rates of regional control (p = 0.990) and disease-specific survival (p = 0.999). However, in the 70 returned questionnaires, patients who underwent END reported higher scores in the domains of appearance, chewing, and speech than did patients who underwent ENI. CONCLUSIONS Our findings suggest that while END and ENI contribute to similar prognoses, END yields superior functional outcomes.

Abstract
Background Elective neck irradiation (ENI) is performed in head and neck cancer patients treated with definitive (chemo)radiotherapy. The aim is to eradicate nodal metastases that are not detectable by pretreatment imaging techniques. It is conceivable that personalized neck irradiation can be performed guided by the results of sentinel lymph node biopsy (SLNB). It is expected that ENI can be omitted to one or both sides of the neck in 9 out of 10 patients, resulting in less radiation side effects with better quality of life. Methods/design This is a multicenter randomized controlled trial aiming to compare safety and efficacy of treatment with SLNB guided neck irradiation versus standard bilateral ENI in 242 patients with cN0 squamous cell carcinoma of the oropharynx, larynx or hypopharynx for whom bilateral ENI is indicated. Patients randomized to the experimental-arm will undergo SLNB. Based on the histopathologic status of the SLNs, patients will receive no ENI (if all SLNs are negative), unilateral neck irradiation only (if a SLN is positive at one side of the neck) or bilateral neck irradiation (if SLNs are positive at both sides of the neck). Patients randomized to the control arm will not undergo SLNB but will receive standard bilateral ENI. The primary safety endpoint is the number of patients with recurrence in regional lymph nodes within 2 years after treatment. The primary efficacy endpoint is patient reported xerostomia-related quality of life at 6 months after treatment. Discussion If this trial demonstrates that the experimental treatment is non-inferior to the standard treatment in terms of regional recurrence and is superior in terms of xerostomia-related quality of life, this will become the new standard of care.

Abstract
Background and purpose Individual elective lymph node irradiation instead of elective neck irradiation is a new concept for head-and-neck cancer (HNC) patients developed for the Magnetic Resonance Image guided linear accelerator (MR-linac). To prepare this, the detectability, volume changes and intra-fraction motion of elective lymph nodes on the MR-linac was assessed. Materials and methods A total of 15 HNC patients underwent diagnostic pre-treatment MRI. Additionally, two MR-linac scans were obtained with a 10-minute time difference in the first week of radiation treatment. Elective lymph node contours inside lymph node levels (Ib-V) were segmented on the pre-treatment MRI and the MR-linac scans and compared on number and maximal transversal diameter. Intra-fraction motion of elective lymph nodes on the MR-linac was estimated using Center of Mass (COM) distances and incremental isotropic expansion of lymph node segmentations. Results Of all 679 detected lymph nodes on the pre-treatment MRI, eight lymph nodes were not detectable on the first MR-linac scan and 16 new lymph nodes were detected. Lymph node diameters between the pre-treatment MRI scan and the MR-linac scan varied from -0.19 to + 0.13 mm. COM distances varied from 1.2 to 1.7 mm and lymph node contours had to be expanded with 3 mm. Conclusions Nearly all elective lymph nodes were detectable on the 1.5T MR-linac scan with no major changes in target volumes compared to the pre-treatment MRI. Simulated intra-fraction motion during the MR-linac scans was smaller than the 5-mm margin that will be used in the first elective lymph node radiation treatment.

Abstract
BACKGROUND AND PURPOSE Sinonasal mucosal melanoma (SNMM) is a rare malignant neoplasm. The regional failure pattern and effectiveness of elective neck irradiation (ENI) were not well defined. Here, we would assess the value of ENI for clinical node negative (cN0) SNMM patients. MATERIALS AND METHODS A total of 107 SNMM patients treated at our institution over a period of 30 years was retrospectively analyzed. RESULTS Five patients had lymph node metastases at diagnosis. Among the 102 cN0 patients analyzed, 37 patients had received ENI, and 65 patients had not. ENI significantly reduced the regional recurrence rate from 23.1% (15/65) to 2.7% (1/37). Ipsilateral levels Ib and II were the most common locations of regional relapse. Multivariate analysis also showed that ENI was the only independent favorable predictor for the achievement of regional control (HR: 9.120; 95% CI: 1.204-69.109; P = 0.032). CONCLUSION This is the largest cohort of SNMM patients from a single institution analyzed for the assessment of the value of ENI on regional control and survival. ENI significantly reduced the regional relapse rate in our study. Ipsilateral levels Ib and II might be considerable when deliver elective neck irradiation, more evidence is needed in the future.

Abstract
Introduction The long-term complication rate in head-and-neck squamous cell carcinoma (HNSCC) patients caused by radiotherapy (RT) can be decreased by restricting elective neck irradiation (ENI) from large adjacent lymph node levels to only individual elective lymph nodes. The primary objective of this study is to treat the first HNSCC patients with individual elective lymph node irradiation by means of a Magnetic Resonance-linac (MR-linac) in order to assess the feasibility. Methods and analysis In this phase I feasibility study, 20 patients will be included with histologically proven cT2-4N0-1M0 HNSCC originating from the oropharynx, hypopharynx or larynx, planned for treatment with primary radiotherapy and bilateral elective neck irradiation (ENI). Patients will be treated with 35 fractions in six weeks, according to the DAHANCA schedule. Individual lymph nodes inside the conventional lymph node levels will be categorized in low-risk, intermediate-risk and high-risk based on cytology, histology and imaging parameters. Low-risk and intermediate-risk lymph nodes will irradiated in 20 and 23 fractions respectively, with a fraction dose of 2 Gy (=40/46 Gy EQD2). The high-risk lymph nodes and the primary tumor will be irradiated in 35 fractions of 2 Gy (=70 Gy equivalent dose in 2 Gy fractions (EQD2)). To limit treatment burden, 20 fractions will be applied on the MR-linac. The last 15 fractions (sequential boost at the primary tumor, intermediate-risk and high-risk lymph nodes) will be applied on a conventional linear accelerator. The main study endpoint is the percentage of fractions that are successfully completed on the MR-linac. Ethics and dissemination With individual elective lymph node irradiation we expect less toxicity and a better quality of life for HNSCC patients. However, as the treatment time on the MR-linac will be longer (30-45 vs 15 min per fraction) we need to examine if patients can endure this new treatment concept.

Abstract
Radiotherapy for locally advanced head and neck cancer classically include large prophylactic node volume. However, the use of these large volumes can be responsible for significant toxicity. Furthermore, the disappointing results of radioimmunotherapy combinations in head and neck tumors raise concerns about radiotherapy's potential negative impact on the immune response when large lymph node volumes are treated. Besides, in other tumor locations, such as lung cancers, the volumes of elective irradiation have been considerably reduced, with the same local control as before. This opinion piece reviews the current state of radiation volumes in head and neck cancers, the rationale for these volumes, the potential impact of radiotherapy on immune response, and the volume changes that would improve the efficacy of radioimmunotherapy combinations.

Abstract
BACKGROUND AND PURPOSE To investigate the feasibility of level Ib sparing in selected nasopharyngeal carcinoma (NPC) patients during intensity-modulated radiation therapy (IMRT) based on the International Guideline. PATIENTS AND MATERIALS Patients with histologically-proven NPC who received definitive IMRT at our group were candidates for this analysis. Other eligibility criteria for analysis were designed according to the recommendation of International Guideline for selective coverage of level Ib. Survival outcomes focused on regional recurrence-free survival (RRFS) and level Ib recurrence rate were analyzed. RESULTS A total of 450 patients were included, 60 of them received level Ib-covering IMRT due to the first three principles of the International Guideline according to our protocol. Of note, patients with level Ib involvement would receive ultrasound guided puncture, only those with positive pathological results would undergo level Ib-covering IMRT. For the remaining 390 patients who only fulfilled the last two criteria and/or level Ib involvement with negative pathological results, level Ib-sparing IMRT was delivered, with a median follow-up time of 112 months (range 6 to 194 months), reported 5- and 10-year RRFS were 95.4% and 92.9%, respectively. Twenty-two patients occurred regional recurrence at censorship (median 44.5 months), only 4(4/390, 1.03%) were recorded as level Ib recurrence. CONCLUSION Level Ib-sparing IMRT should be safe and feasible for patients who only had level II involvement with ECE, and/or had a MAD of greater than 2 cm in level II, and/or level Ib involvement with negative pathological results. Further well-designed multi-center prospective trials should be conducted.

Abstract
OBJECTIVE To explore the effects of elective neck irradiation (ENI) in clinically node-negative (cN0) sinonasal adenoid cystic carcinoma (SNACC). MATERIALS AND METHODS Between January 2000 and December 2016, 60 patients with cN0 sinonasal adenoid cystic carcinoma receiving surgery combined with radiotherapy were analyzed retrospectively, there were 39 received ENI (ENI group) and 21 with no ENI (non-ENI group). Propensity score matching (PSM) was performed to balance clinical factors and match patients. Kaplan-Meier method and Cox proportional hazard model were used to evaluate the impact of ENI on regional relapse risk and survival outcomes. RESULTS The median follow-up time for our cohort was 82.0 months (12.4-190.7 months). Four patients (6.7%) developed neck nodal relapses, with a median time to progression of 38.8 months. Among them, two patients in ENI group but failed out-field. After PSM, 21 patients were matched in each group. The 7-year regional relapse-free survival (RRFS), distant metastasis free survival (DMFS), progression-free survival (PFS), and overall survival (OS) between ENI group and non-ENI group were 85.4% vs 73.3% (p = 0.845), 65.2% vs 65.6% (p = 0.548), 68.3% vs 66.2% (p = 0.425), and 87.3% vs 84.0% (p = 0.953). Multivariate Cox analysis showed ENI was not an independent prognostic factor associated with RRFS, DMFS, PFS and OS. CONCLUSION Our findings firstly demonstrated the omission of elective neck irradiation in the management of cN0 sinonasal adenoid cystic carcinoma might be safe without compromising disease control and should be further investigated.

Abstract
OBJECTIVE Optimal neck management in patients with olfactory neuroblastoma (ONB), a rare malignancy, remains uncertain. This study aimed to analyse patterns of cervical lymph node metastases and corresponding clinical outcomes and to investigate the value of elective neck irradiation (ENI) in this population. METHODS AND MATERIALS This study retrospectively reviewed clinical records, imaging findings, nodal metastasis features and treatment data of 217 patients with ONB treated at our hospital during 1991-2019. Univariate and multivariate analyses were used to assess the influence of cervical lymph node involvement on treatment outcomes. Survival and regional failure rates were compared between patients with or without ENI. RESULTS Thirty-two patients (14.7%) presented initially with cervical lymph node metastases, most frequently at levels II (10.6%, 23/217) and VIIa (5.5%, 12/217). Patients with and without cervical node metastasis differed significantly in overall (OS) (41.9% vs. 86.1%, p < 0.001), progression-free (PFS) (41.9% vs. 84.8%, p < 0.001), regional failure-free (45.9% vs. 89%, p < 0.001) and distant metastasis-free survival (41.5% vs. 86.1%, p < 0.001). Cervical lymph involvement was an independent factor affecting poor OS (hazard ratio, 0.184, 95% confidence interval, 0.078-0.436, p < 0.001) and PFS (hazard ratio, 0.198, 95% confidence interval, 0.088-0.445, p < 0.001). Moreover, 43.8% patients (95/217) underwent ENI, which significantly reduced the incidence of regional recurrence from 10.7% to 3.2% (χ2 = 4.396, p = 0.036) but did not significantly affect other survival outcomes. Regional failures could be resolved using salvage treatment. CONCLUSIONS Our findings indicate the importance of systematic therapy for patients with initial cervical lymph node metastases. ENI is not recommended for N0 disease.

Abstract
Purpose The indication of elective neck treatment (ENT) for clinically N0 (cN0) paranasal sinus (PNS) carcinoma remains unclear. We aimed to investigate different treatment outcomes regarding ENT and propose optimal recommendations for ENT. Materials and Methods We identified patients with cN0 PNS carcinoma who underwent curative-intent treatment between 1992 and 2015. Survival outcomes and pattern of failure were compared between patients who received ENT and those who did not. We sought to identify significant patient or pathologic factors regarding treatment outcomes. Results Among 124 patients meeting the inclusion criteria, 40 (32%) received ENT (‘ENT (+) group’) and 84 (68%) did not (‘ENT (−) group’). With a median follow-up of 54 months, the 5-year overall survival (OS) was 67%, and the 5-year progression-free survival (PFS) was 45%. There was no significant difference between the ENT (+) and ENT (−) groups regarding OS (p = 0.67) and PFS (p = 0.50). Neither group showed a significantly different pattern of failure, including regional failure (p = 0.91). There was no specific benefit, even in the subgroups analysis by tumor site, histologic type, and T stage. Nevertheless, patients who ever had regional and/or distant failure showed significantly worse prognosis. Conclusion ENT did not significantly affect the survival outcome or pattern of failure in patients with cN0 PNS carcinomas, showing that ENT should not be generalized in this group. However, further discussion on the optimal strategy for ENT should continue because of the non-negligible regional failure rates and significantly worse prognosis after regional failure events.

Abstract
OBJECTIVES This study was aimed to characterize patterns of lymphatic spread and assess the value of prophylactic elective neck irradiation (ENI) for esthesioneuroblastoma (ENB). METHODS A retrospectively analysis of 116 patients with newly diagnosed ENB at our institution over 35-year period was undertaken. RESULTS 32 patients (28%) presented lymph node metastasis at initial diagnosis, the common sites involved were level II, Ib, level III and VIIa. Among 80 N-negative patients staged in Modified Kadish B/C, 50 patients were delivered with ENI, 30 patients were not. The 5-year regional failure-free survival was 98% in patients treated with ENI and 75% in patients without ENI (p=0.005), regional failure rate decreased significantly from 23% (7/30) to 2% (1/50) after ENI (p=0.002). Multivariate analysis also suggested that ENI was an independent favorable predictor for regional controlling (HR, 0.102; 95% CI: 0.012-0.848; p=0.035). CONCLUSIONS This is the largest cohort of ENB so far in a single institute, and also the first detailed description of nodal spread patterns of N-positive ENB. Elective neck irradiation reduced the regional failure significantly and should be recommended as a part of initial treatment strategy for patients staged with Modified Kadish B/C.

Abstract
OBJECTIVES This is to report treatment results of major salivary gland cancer by surgery with or without postoperative radiation therapy (PORT). METHODS Between March 1995 and January 2006, 94 patients with primary major salivary cancer underwent curative surgical resection at Samsung Medical Center. The parotid gland was the most commonly involved (73, 77.7%), followed by the submandibular and the sublingual. Neck dissection was added in 28 patients, and PORT was individually recommended to those with risk factors. Seventy-five (79.8%) patients received PORT. PORT volume included primary tumor bed and pathologically involved regional lymphatics, and no additional effort was made for elective nodal irradiation. The median total doses were 56.0 Gy to primary site and 58.7 Gy to regional lymphatics. RESULTS After median follow-up of 49 months, 21 patients had relapsed: 20 in PORT; and one in surgery alone group. As the first site of failure, distant metastasis was the most common (17 patients). Local recurrence occurred in three, and regional relapse in one. The lung was the most common site (10 patients), followed by the bone, and the brain. Five-yr disease free survival (DFS), local control, and overall survival (OS) rates were 74.4% and 94.7%, 96.0% and 100%, and 78.2% and 100% in PORT and surgery alone groups, respectively. On multivariate analysis, DFS was significantly affected by pN+ (hazard ratio [HR], 3.624; P=0.0319), while OS was by pN+ (HR, 7.138; P=0.0034) and perineural invasion (HR, 5.073; P=0.0187). CONCLUSION Based on our experience, the patients with early stage major salivary gland cancer with low risk can be effectively treated by surgery alone, and those who with risk factors can achieve excellent local and regional control by adding PORT. Omitting elective neck irradiation in patients with N0 disease seems a feasible strategy under accurate clinical evaluation. An effort is needed to decrease distant metastasis through further clinical trials.
