Unilateral versus bilateral nodal irradiation:Current evidence in the treatment of squamous cell carcinoma of the head and neck
Cancers of the head and neck region often present with nodal involvement. There is a long-standing convention within the community of head and neck radiation oncology to irradiate both sides of the neck electively in almost all cases to include both macroscopic and microscopic disease extension (so called elective nodal volume). International guidelines for the selection and delineation of the elective lymph nodes were published in the early 2000s and were updated recently. However, diagnostic imaging techniques have improved the accuracy and reliability of nodal staging and as a result, small metastases that used to remain undetected and were thus in the past included in the elective nodal volume, will now be included in high-dose volumes. Furthermore, the elective nodal areas are situated close to the parotid glands, the submandibular glands and the swallowing muscles. Therefore, irradiation of a smaller, more selected volume of the elective nodes could reduce treatment-related toxicity. Several researchers consider the current bilateral elective neck irradiation strategies an overtreatment and show growing interest in a unilateral nodal irradiation in selected patients. The aim of this article is to give an overview of the current evidence about the indications and benefits of unilateral nodal irradiation and the use of SPECT/CT-guided nodal irradiation in squamous cell carcinomas of the head and neck
Origin and clinical relevance of chromosomal aberrations other than the common trisomies detected by genome-wide NIPS: Results of the TRIDENT study
PurposeNoninvasive prenatal screening (NIPS) using cell-free DNA in maternal blood is highly sensitive for detecting fetal trisomies 21, 18, and 13. Using a genome-wide approach, other chromosome anomalies can also be detected. We report on the origin

Vaginal mucositis in patients with gynaecological cancer undergoing (chemo-)radiotherapy: a retrospective analysis
The objective of this retrospective analysis was to determine the incidence and extent of vaginal mucositis (VM) in women with gynaecological cancer undergoing external (chemo)radiation therapy (CRT). A retrospective analysis was set up to collect data on the incidence and severity of VM in women treated with external pelvic RT for gynaecological cancer at the Jessa Hospital, Hasselt and ZOL, Genk, BE between January 2017 and June 2018. At the start and end of their external (C)RT, they rated the frequency and intensity of five common symptoms of VM. Thirty-three patients treated with RT for gynaecological cancer met the inclusion criteria. A non-negligible proportion of patients already experienced at least one VM symptom to any degree before the start of RT, a proportion that further increased towards the end of the RT (73%). At the end of RT, on average, about 25% of these patients reported moderate-to-severe symptoms (against about 7% before the (C)RT). These results suggest that VM is a rather frequent side effect in gynaecological cancer patients that aggravates during treatment up to a moderate severity level. Although the small sample size, these data highlight the need for attention to VM.Impact Statement What is already known about this topic? Radiotherapy plays an important role in the treatment of gynaecological malignancies. A debilitating complication in patients undergoing pelvic radiotherapy is vaginal mucositis, an inflammation of the vaginal mucosal lining. To date, the incidence of vaginal mucositis is still not well documented. What this paper adds? A non-negligible proportion of patients already experienced at least one symptom related to vaginal mucositis before the start of radiotherapy. Most patients presented mild to moderate vaginal mucositis symptoms at the end of external pelvic radiotherapy. Burning sensation, pruritus, and pain were the most frequently documented radiotherapy-induced complications. The implications of this paper: Vaginal mucositis is an underrated side effect of pelvic radiotherapy that needs to be tackled multidisciplinary by a team of nurses, radiotherapists, oncologists, and gynaecologists. The team should tackle the complication from the start of radiotherapy by using the most appropriate measures. Due to a possible link between acute vaginal mucositis and late vaginal toxicity, the team needs to follow-up patient’s post-radiotherapy to support patients in late complications and advise/encourage patients in performing vaginal dilatation to prevent vaginal stenosis
Proton Therapy for Squamous Cell Carcinoma of the Head and Neck: Early Clinical Experience and Current Challenges
Proton therapy (PT) is a promising development in radiation oncology, with the potential to further improve outcomes for patients with squamous cell carcinoma of the head and neck (HNSCC). By utilizing the finite range of protons, healthy tissue can be spared from beam exit doses that would otherwise be irradiated with photon-based treatments. Current evidence on PT for HNSCC is limited to comparative dosimetric analyses and retrospective single-institution series. As a consequence, the recognized indications for the reimbursement of PT remain scarce in most countries. Nevertheless, approximately 100 PT centers are in operation worldwide, and initial experiences for HNSCC are being reported. This review aims to summarize the results of the early clinical experience with PT for HNSCC and the challenges that are currently faced
Home-based intensive treatment of chronic radiation-associated dysphagia in head and neck cancer survivors (HIT-CRAD trial)
BACKGROUND: Chronic radiation-associated dysphagia (C-RAD) is considered to be one of the most severe functional impairments in head and neck cancer survivors treated with radiation (RT) or chemoradiation (CRT). Given the major impact of these late toxicities on patients’ health and quality of life, there is a strong need for evidence-based dysphagia management. Although studies report the benefit of strengthening exercises, transference of changes in muscle strength to changes in swallowing function often remains limited. Therefore, combining isolated strengthening exercises with functional training in patients with C-RAD may lead to greater functional gains. METHODS: This 3-arm multicenter randomized trial aims to compare the efficacy and possible detraining effects of mere strengthening exercises (group 1) with a combination of strengthening exercises and functional swallowing therapy (group 2) and non-invasive brain stimulation added to that combination (group 3) in 105 patients with C-RAD. Patients will be evaluated before and during therapy and 4 weeks after the last therapy session by means of swallowing-related and strength measures and quality of life questionnaires. DISCUSSION: Overall, this innovative RCT is expected to provide new insights into the rehabilitation of C-RAD to optimize post-treatment swallowing function.

Increasing adherence to prophylactic swallowing exercises during head and neck radiotherapy : the multicenter, randomized controlled PRESTO-trial
BACKGROUND: Prophylactic swallowing exercises (PSE) during radiotherapy can significantly reduce dysphagia after radiotherapy in head and neck cancer (HNC). However, its positive effects are hampered by low adherence rates during the burdensome therapy period. Hence, the main goal of this multicenter randomized controlled trial (RCT) was to investigate the effect of 3 different service-delivery modes on actual patients’ adherence. METHODS: A total of 148 oropharyngeal cancer patients treated with primary (chemo)radiotherapy were randomly assigned to a 4 weeks PSE program, either diary-supported (paper group; n = 49), app-supported (app group; n = 49) or therapist-supported (therapist group; n = 50). Participants practiced 5 days/week, daily alternating tongue strengthening exercises with chin tuck against resistance exercises. Adherence was measured as the percentage of completed exercise repetitions per week (%reps). Statistical analysis was performed by means of SPSSv27, using Linear Mixed-effects Models with post hoc pairwise testing and Bonferroni-Holm correction. RESULTS: Adherence and evolution of adherence over time was significantly different between the three groups (p < .001). Adherence rates decreased in all three groups during the 4 training weeks (p < .001). During all 4 weeks, the therapist group achieved the highest adherence rates, whilst the app group showed the lowest adherence rates. CONCLUSIONS: PSE adherence decreased during the first 4 radiotherapy weeks regardless of group, but with a significant difference between groups. The therapist group achieved the highest adherence rates with a rather limited decline, therefore, increasing the face-to-face contact with a speech-language therapist can overcome the well-known problem of low adherence to PSE in this population.
