Pathways for the rehabilitation of resection defects in the maxilla.

Oral rehabilitation of head and neck cancer patients is an integral component of the care pathway. Maxillectomy procedures can cause significant defects, such as oronasal fistulas, loss of support for the cheek and lip, aesthetic defects in the middle third of the face and functional impairments. Orofacial rehabilitation plays a fundamental role in restoring aesthetics and functional capabilities, such as speech, mastication and deglutition.Rehabilitation of maxillectomy patients poses a challenge for both clinicians and patients. This paper utilises case examples to demonstrate the treatment options for the oral rehabilitation of these patients. We will summarise the treatment pathways for conventional obturators, delayed (secondary) implant retained fixed rehabilitation following composite free flap and early rehabilitation using a zygomatic implant perforated flap technique. This paper aims to highlight the challenges in treatment planning and the importance of a multidisciplinary approach in improving patient outcomes.

Loss of FANCD2 and related proteins may predict malignant transformation in oral epithelial dysplasia.

OBJECTIVE: Predicting malignant transformation (MT) in oral epithelial dysplasia (OED) is challenging. The higher rate of MT reported in nonsmokers suggests an endogenous etiology in oncogenesis. We hypothesize that loss of FANCD2 and associated proteins could influence genomic instability and MT in the absence of environmental carcinogens. STUDY DESIGN: Longitudinal archival samples were obtained from 40 individuals with OED: from diagnosis to the most recent review in 23 patients with stable OED or until excision of the squamous cell carcinoma in 17 patients with unstable OED undergoing MT. Histopathological reassessment, immunohistochemistry for FANCD2, and Western blotting for phosphorylation/monoubiquitylation status of ATR, CHK1, FANCD2, and FANCG were undertaken on each tissue sample. RESULTS: Decreased expression of FANCD2 was observed in the diagnostic biopsies of OED lesions that later underwent MT. Combining the FANCD2 expression scores with histologic grading more accurately predicted MT (P = .005) than histology alone, and it correctly predicted MT in 10 of 17 initial biopsies. Significantly reduced expression of total FANCD2, pFANCD2, pATR, pCHK-1, and pFANCG was observed in unstable OED. CONCLUSIONS: There is preliminary evidence that defects in the DNA damage sensing/signaling/repair cascade are associated with MT in OED. Loss of expression of FANCD2 protein in association with a higher histologic grade of dysplasia offered better prediction of MT than clinicopathologic parameters alone.

Improving quality of life through the routine use of the patient concerns inventory for head and neck cancer patients: main results of a cluster preference randomised controlled trial.

PURPOSE: The patient concerns inventory (PCI) is a prompt list allowing head and neck cancer (HNC) patients to discuss issues that otherwise might be overlooked. This trial evaluated the effectiveness of using the PCI at routine outpatient clinics for one year after treatment on health-related QOL (HRQOL). METHODS: A pragmatic cluster preference randomised control trial with 15 consultants, 8 'using' and 7 'not using' the PCI intervention. Patients treated with curative intent (all sites, disease stages, treatments) were eligible. RESULTS: Consultants saw a median (inter-quartile range) 16 (13-26) patients, with 140 PCI and 148 control patients. Of the pre-specified outcomes, the 12-month results for the mean University of Washington Quality of Life (UW-QOLv4) social-emotional subscale score suggested a small clinical effect of intervention of 4.6 units (95% CI 0.2, 9.0), p = 0.04 after full adjustment for pre-stated case-mix. Results for UW-QOLv4 overall quality of life being less than good at 12 months (primary outcome) also favoured the PCI with a risk ratio of 0.83 (95% CI 0.66, 1.06) and absolute risk 4.8% (- 2.9%, 12.9%) but without achieving statistical significance. Other non-a-priori analyses, including all 12 UWQOL domains and at consultant level also suggested better HRQOL with PCI. Consultation times were unaffected and the number of items selected decreased over time. CONCLUSION: This novel trial supports the integration of the PCI approach into routine consultations as a simple low-cost means of benefiting HNC patients. It adds to a growing body of evidence supporting the use of patient prompt lists more generally.

Improving quality of life through the routine use of the patient concerns inventory for head and neck cancer patients: baseline results in a cluster preference randomised controlled trial.

PURPOSE: The main aim of this paper is to present baseline demographic and clinical characteristics and HRQOL in the two groups of the Patient Concerns Inventory (PCI) trial. The baseline PCI data will also be described. METHODS: This is a pragmatic cluster preference randomised control trial with 15 consultant clusters from two sites either 'using' (n = 8) or 'not using' (n = 7) the PCI at a clinic for all of their trial patients. The PCI is a 56-item prompt list that helps patients raise concerns that otherwise might be missed. Eligibility was head and neck cancer patients treated with curative intent (all sites, stage of disease, treatments). RESULTS: From 511 patients first identified as eligible when screening for the multi-disciplinary tumour board meetings, 288 attended a first routine outpatient baseline study clinic after completion of their treatment, median (IQR) of 103 (71-162) days. At baseline, the two trial groups were similar in demographic and clinical characteristics as well as in HRQOL measures apart from differences in tumour location, tumour staging and mode of treatment. These exceptions were cluster (consultant) related to Maxillofacial and ENT consultants seeing different types of cases. Consultation times were similar, with PCI group times taking about 1 min longer on average (95% CL for the difference between means was from - 0.7 to + 2.2 min). CONCLUSION: Using the PCI in routine post-treatment head and neck cancer clinics do not elongate consultations. Recruitment has finished but 12-month follow-up is still ongoing.

Management of proliferative verrucous leukoplakia: Justification for a conservative approach.

BACKGROUND: Proliferative verrucous leukoplakia (PVL) is a progressive, multifocal, exophytic form of leukoplakia with high rates of malignant transformation. The purpose of this study was to evaluate a cohort of patients with PVL in a single tertiary referral clinic. METHOD: Cases meeting accepted diagnostic criteria were reviewed with regard to their pathology, demographic characteristics, management, and outcomes. Human papillomavirus (HPV) testing was undertaken on a subset. RESULTS: Almost half of the 48 patients with PVL (48%; n = 23) underwent malignant transformation after a median 23.4 months. The characteristics of this cohort were similar to those previously described, but management was notably more conservative. Conservative management of PVL was used in 92% of our patients, but the clinical outcomes seem comparable with previously described cohorts in which PVL was predominantly treated by surgical excision. All HPV testing was negative. CONCLUSION: Aggressive surgical intervention in the premalignant phase of PVL may not influence the rate of malignant transformation.
