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

INTRODUCTION AND IMPORTANCE: Parotid gland swelling with facial nerve palsy is highly suggestive of a malignancy. Facial nerve palsy is however rarely caused by a parotid abscess. We hereby present two cases, propose treatment and present a review of the literature. CASE PRESENTATION AND CLINICAL DISCUSSION: One 75-year-old female and one 81-year-old female presented with a facial nerve paralysis, both caused by a parotid gland abscess. Broad-spectrum antibiotics and incision and drainage was commenced in both cases. Both patients showed good clinical improvement, however, without facial nerve improvement. Magnetic resonance imaging (MRI) scans showed no malignancies at presentation nor during follow-up after one year. CONCLUSION: Facial nerve palsy is rarely caused by a parotid abscess. Incision and drainage in combination with antibiotic treatment is recommended. Chances of facial nerve recovery seem somewhat higher in patients with facial nerve paresis than those with a paralysis.
