PURPOSE: To provide evidence-based recommendations for practicing physicians and other healthcare providers on the management of salivary gland malignancy.METHODS: ASCO convened an Expert Panel of medical oncology, surgical oncology, radiation oncology, neuroradiology, pathology, and patient advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2020. Outcomes of interest included survival, diagnostic accuracy, disease recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.RESULTS: The literature search identified 293 relevant studies to inform the evidence base for this guideline. Six main clinical questions were addressed, which included subquestions on preoperative evaluations, surgical diagnostic and therapeutic procedures, appropriate radiotherapy techniques, the role of systemic therapy, and follow-up evaluations.RECOMMENDATIONS: When possible, evidence-based recommendations were developed to address the diagnosis and appropriate preoperative evaluations for patients with a salivary gland malignancy, therapeutic procedures, and appropriate treatment options in various salivary gland histologies.

Objectives: Adenoid cystic carcinoma (ACC) is often treated with surgery, with or without adjuvant radiation therapy (RT). We evaluated disease characteristics, treatments, and potentially prognostic variables in patients with ACC. Methods: Our retrospective analysis considered consecutive cases of ACC presenting at a tertiary care hospital between 2000 and 2014. Factors predictive of overall survival (OS) and disease-free survival (DFS) were identified by univariate analysis. Results: The 60 patients analyzed had a mean age of 58 years (range: 22-88 years), with a 2:1 female:male ratio. Tumour locations included the major salivary glands (40% parotid, 17% submandibular and sublingual), the oro-nasopharyngeal cavity (27%), and other locations (16%). Of the 60 patients, 35 (58%) received surgery with adjuvant RT; 12 (20%), RT only; 13 (22%), surgery only. Of 18 patients (30%) who experienced a recurrence within 5 years, 3 (5%) developed local recurrence only, and the remaining 15 (25%), distant metastasis. The 5-year OS and DFS were 64.5% [95% confidence interval (CI): 45.9% to 78.1%] and 46.2% (95% CI: 29.7% to 61.2%) respectively. In patients without recurrence, 5-year OS was 77% (95% CI: 52.8% to 89.9%), and in patients with recurrence, it was 42.7% (95% CI: 15.8% to 67.6%). Patients treated with RT only had a 5-year OS of 9.2%. Predictors of 5-year DFS were TNM stage, T stage, nodal status, treatment received, and margin status; age, nodal status, treatment received, and margin status predicted 5-year OS. Conclusions: Despite surgery and RT, one third of patients with ACC experience distant recurrence. Patients whose tumours are not amenable to surgery have a poor prognosis, indicating a need for alternative approaches to improve outcomes.

Background: Research on physical activity and nutrition interventions aimed at positively impacting symptom management, treatment-related recovery and quality of life has largely excluded head and neck (HN) cancer populations. This translates into a lack of clinical programming available for these patient populations. HN cancer patients deal with severe weight loss, with more than 70% attributed to lean muscle wasting, leading to extended recovery times, decreased quality of life (QoL), and impaired physical functioning. To date, interventions to address body composition issues have focused solely on diet, despite findings that nutritional therapy alone is insufficient to mitigate changes. A combined physical activity and nutrition intervention, that also incorporates important educational components known to positively impact behaviour change, is warranted for this population. Our pilot work suggests that there is large patient demand and clinic support from the health care professionals for a comprehensive program. Methods/Design: Therefore, the purpose of the present study is to examine the impact and timing of a 12-week PA and nutrition intervention (either during or following treatment) for HN cancer patients on body composition, recovery, serum inflammatory markers and quality of life. In addition, we will examine the impact of a 12-week maintenance program, delivered immediately following the intervention, on adherence, patient-reported outcomes (i.e., management of both physical and psychosocial treatment-related symptoms and side-effects), as well as return to work. Discussion: This research will facilitate advancements in patient wellness, survivorship, and autonomy, and carve the path for a physical-activity and wellness-education model that can be implemented in other cancer centers.

Head and neck cancer (HNC) surgical patients experience a high symptom burden. Multiphasic exercise prehabilitation has the potential to improve patient outcomes, and to implement it into the care pathway, the perspectives of patients and healthcare providers (HCPs) must be considered. The purpose of this study was thus to gather feedback from HNC surgical patients and HCPs on building exercise into the standard HNC surgical care pathway. Methods: Semi-structured interviews were conducted with patients and HCPs as part of a feasibility study assessing patient-reported outcomes, physical function, and in-hospital mobilization. Interview questions included satisfaction with study recruitment, assessment completion, impact on clinical workflow (HCPs), and perceptions of a future multiphasic exercise prehabilitation program. This study followed an interpretive description methodology. Results: Ten patients and ten HCPs participated in this study. Four themes were identified: (1) acceptability and necessity of assessments, (2) the value of exercise, (3) the components of an ideal exercise program, and (4) factors to support implementation. Conclusion: These findings highlight the value of exercise across the HNC surgical timeline from both the patient and the HCP perspective. Results have informed the implementation of a multiphasic exercise prehabilitation trial in HNC surgical patients.

Background: There is growing recognition of the importance of reporting preliminary work on the feasibility of a trial. The present study aimed to assess the feasibility of (1) a proposed fitness testing battery, and (2) processes related to the implementation of cancer-specific exercise programming in a community setting. Methods/Design: A randomized controlled implementation feasibility trial was performed in advance of a large-scale implementation study. Eligible participants within 18 months of a cancer diagnosis were randomized to immediate or delayed community-based exercise at YMCA locations in Calgary and Edmonton, Canada for an 8-week period. The primary outcome for the trial was the feasibility of the physical fitness testing battery, defined as a 70% or greater completion rate across the 24-week study period. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework was used to evaluate processes related to implementation of the exercise program across the two sites. Results: Eighty participants were recruited, 73 (91%) completed the 8-week trial, and 68 (85%) completed the 16- and 24-week follow-ups. Sixty participants (75%) completed the full physical fitness test battery at each time point, and 59 (74%) completed the patient-reported outcome measures. Statistically significant between-group differences were found in favor of the exercise group for functional aerobic capacity, upper and lower extremity strength, and symptoms. Differences were found between the sites, however, in completion rates and processes related to program implementation. Discussion: Findings suggest the need for minor adaptations to the physical fitness battery and outcome measures to better fit the community context. While findings support feasibility, context-specific challenges related to implementation processes were identified.
