Characterization of orofacial features in sclerodermatous chronic graft-versus-host disease.

BACKGROUND: Chronic graft-versus-host disease (cGVHD) is a leading cause of morbidity and mortality following allogeneic hematopoietic cell transplantation (alloHCT). The sclerodermatous form of cGVHD can be particularly debilitating; however, orofacial sclerodermatous involvement remains poorly described. OBJECTIVE: To characterize orofacial features of sclerodermatous cGVHD in a single center cohort of patients who underwent alloHCT. STUDY DESIGN: Retrospective data were collected from electronic medical records and analyzed descriptively. RESULTS: There were 39 patients who received alloHCT between 1993 and 2017 and developed orofacial sclerodermatous cGVHD. Concomitant cutaneous sclerodermatous cGVHD was common (n = 20, 51%). Orofacial sclerodermatous cGVHD features included fibrous bands of the buccal mucosa (n = 23, 59%), limited mouth opening (n = 19, 54%), perioral fibrosis (n = 8, 21%), and focal gingival recession (n = 4, 10%). Oral mucosal fibrosis was observed at the site of active or resolved chronic lichenoid inflammation in 30 patients, with all but two also presenting with a history of ulcerations. Management included jaw stretching exercises (n = 10; 6 stable/improved), surgery (n = 3; 2 improved), and intralesional corticosteroid injections (n = 2; 2 improved). CONCLUSIONS: Orofacial involvement with sclerodermatous cGVHD can present with multiple manifestations including fibrous banding, limited mouth opening, perioral fibrosis, and focal gingival recession. Surgical and non-surgical management strategies may improve clinical function and reduce morbidity.

Oral and cutaneous immune-related adverse events in cancer patients: Prevalence and overall survival.

OBJECTIVES: To assess the prevalence of cutaneous and oral immune-related adverse events (irAEs) in cancer patients, risk factors for its development, and overall survival (OS). MATERIALS AND METHODS: This retrospective observational study which included 748 medical records of cancer patients who received immune checkpoint inhibitors (ICIs). Demographic and clinicopathological characteristics were collected and analyzed. RESULTS: Most patients were male (59.4%), with stage IV cancer (65%) and received pembrolizumab (46.7%). Four hundred fourteen (55.34%) patients developed cutaneous lesions, 84 (11.2%) developed oral mucosal lesions, and 70 (9.3%) developed xerostomia. The median time for irAEs development was 11 weeks for cutaneous and oral mucosal lesions, and 21.5 weeks for xerostomia. Patients who received PD-1 + CTLA-4 had a higher risk for developing cutaneous irAEs (p = 0.001), while those who underwent ICI and concurrent chemotherapy had a higher risk (p = 0.008) for developing oral mucosal lesions. Patients who presented oral and cutaneous irAEs had better OS than those who did not present (p = 0.0001). CONCLUSION: Cutaneous effects affected more than half of the patients, while oral effects and xerostomia were found in around 11% and 9% of patients, respectively. Concurrent chemotherapy and PD-1 + CTLA-4 were more associated with oral and cutaneous irAEs, respectively. Patients who developed such irAEs had better overall survival.

Oral health-related quality of life after radiation therapy for head and neck cancer: the OraRad study.

PURPOSE: Head and neck cancer (HNC) treatment results in morbidity impacting quality of life (QOL) in survivorship. This analysis evaluated changes in oral health-related QOL (OH-QOL) up to 2 years after curative intent radiation therapy (RT) for HNC patients and factors associated with these changes. METHODS: 572 HNC patients participated in a multicenter, prospective observational study (OraRad). Data collected included sociodemographic, tumor, and treatment variables. Ten single-item questions and 2 composite scales of swallowing problems and senses problems (taste and smell) from a standard QOL instrument were assessed before RT and at 6-month intervals after RT. RESULTS: The most persistently impacted OH-QOL variables at 24 months included: dry mouth; sticky saliva, and senses problems. These measures were most elevated at the 6-month visit. Aspects of swallowing were most impacted by oropharyngeal tumor site, chemotherapy, and non-Hispanic ethnicity. Problems with senses and dry mouth were worse with older age. Dry mouth and sticky saliva increased more among men and those with oropharyngeal cancer, nodal involvement, and use of chemotherapy. Problems with mouth opening were increased by chemotherapy and were more common among non-White and Hispanic individuals. A 1000 cGy increase in RT dose was associated with a clinically meaningful change in difficulty swallowing solid food, dry mouth, sticky saliva, sense of taste, and senses problems. CONCLUSIONS: Demographic, tumor, and treatment variables impacted OH-QOL for HNC patients up to 2 years after RT. Dry mouth is the most intense and sustained toxicity of RT that negatively impacts OH-QOL of HNC survivors. GOV IDENTIFIER: NCT02057510; first posted February 7, 2014.

Validation of healthcare professional proxy-reported children's International Mucositis Evaluation Scale.

OBJECTIVE: The objective was to describe the reliability and validity of the healthcare professional proxy-report version of the Children's International Mucositis Evaluation Scale (ChIMES). METHODS: We included pediatric patients who were between 4 and 21 years of age and scheduled to undergo hematopoietic cell transplantation. Mucositis was evaluated by trained healthcare professionals who scored ChIMES, the World Health Organization oral toxicity scale, mouth, and throat pain visual analogue scale, National Cancer Institute-Common Terminology Criteria and the Oral Mucositis Daily Questionnaire. Measures were completed daily and evaluated on days 7-17 post-stem cell infusion for this analysis. Psychometric properties examined were internal consistency, test-retest reliability (days 13 and 14), and convergent construct validity. RESULTS: There were 192 participants included. Cronbach's alpha was 0.90 for ChIMES Total Score and 0.93 for ChIMES Percentage Score. Test-retest reliability were as follows: intraclass correlation coefficient (ICC) 0.82 (95% confidence interval (CI) 0.77-0.85) for ChIMES Total Score and ICC 0.82 (95% CI 0.77-0.86) for ChIMES Percentage Score. In terms of construct validation, all correlations between measures met or exceeded those hypothesized (all p < 0.05). CONCLUSIONS: The healthcare professional proxy-report version of ChIMES is reliable and valid for children and adolescents undergoing hematopoietic cell transplantation.

Dental evaluation and clearance prior to allogeneic hematopoietic cell transplantation.

INTRODUCTION: Dental examination and stabilization are performed prior to allogeneic hematopoietic cell transplantation to decrease infection risk during neutropenia. Burden of dental disease and treatment need is not well characterized in this population. OBJECTIVES: This report describes the dental status of a cohort of patients within the Chronic Graft-versus-Host Disease Consortium and treatment rendered prior to transplant. METHODS: The cohort included 486 subjects (Fred Hutchinson: n = 245; Dana-Farber: n = 241). Both centers have institutional-based dental clearance programs. Data were retrospectively abstracted from medical records by calibrated oral health specialists. RESULTS: The median age at transplant was 55.9 years, 62.1% were male, and 88% were white. Thirteen patients were edentulous (2.7%). The mean teeth among dentate patients before clearance was 26.0 (SD, 4.6). Dental findings included untreated caries (31.2%), restorations (91.6%), endodontically treated teeth (48.1%), and dental implants (5.7%). Pretransplant procedures during clearance included endodontic therapy (3.6%; mean = 0.1 teeth), restorations (25.1%; mean = 0.7), dental prophylaxis (59.2%), scaling/root planing (5.1%), and extraction (13.2%; mean = 0.3). The mean teeth after clearance was 25.6 (SD, 5.0). CONCLUSIONS: Retrospective analysis of pre-AlloHCT dental data in subjects at two large transplant centers identified low levels of dental need. Findings suggest high access to care.

Impact of photobiomodulation for prevention of oral mucositis on the quality of life of patients with head and neck cancer: a systematic review.

The aim of this study was to perform a systematic review to evaluate the impact of photobiomodulation therapy (PBMT) for the prevention of oral mucositis (OM) on the quality of life (QoL) of patients with head and neck cancer (HNC) undergoing radiation therapy. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The search strategy was performed in five electronic databases (Cochrane, Embase, PubMed, Scopus, and Web of Science). The included studies assessed the QoL of patients undergoing radiation therapy (RT) for HNC and undergoing PBMT for the management of OM. Seven articles met the eligibility criteria. Data extraction was performed in the selected studies including the PBMT parameters (active medium, application procedure, wavelength, fluence, power, irradiance, irradiation time, spot size, energy per point, schedule of irradiation, and total energy). The included studies were qualitatively analyzed, and descriptive analyses were performed. Also, summary results were evaluated for group comparison analysis. All included studies confirmed a decrease in the QoL of the patients that developed OM throughout the RT progress when compared to baseline. Of the informed cases, most of the patients who received PBMT showed grades 1 and 2 OM, while the control group showed more individuals with severe forms of OM (grades 3 and 4). In this sense, patients submitted to PBMT reported better QoL at the end of the treatment compared with the control group. PBMT used for the management of OM preserves the QoL of patients with head and neck cancer.

Exposed bone in patients with head and neck cancer treated with radiation therapy: An analysis of the Observational Study of Dental Outcomes in Head and Neck Cancer Patients (OraRad).

BACKGROUND: Patients with head and neck cancer (HNC) treated with radiation therapy (RT) are at risk for jaw osteoradionecrosis (ORN), which is largely characterized by the presence of exposed necrotic bone. This report describes the incidence and clinical course of and risk factors for exposed intraoral bone in the multicenter Observational Study of Dental Outcomes in Head and Neck Cancer Patients (OraRad) cohort. METHODS: Participants were evaluated before RT and at 6, 12, 18, and 24 months after RT. Exposed bone was characterized by location, sequestrum formation, and other associated features. The radiation dose to the affected area was determined, and the history of treatment for exposed bone was recorded. RESULTS: The study enrolled 572 participants; 35 (6.1%) were diagnosed with incident exposed bone at 6 (47% of reports), 12 (24%), 18 (20%), and 24 months (8%), with 60% being sequestrum and with 7 cases (20%) persisting for >6 months. The average maximum RT dose to the affected area of exposed bone was 5456 cGy (SD, 1768 cGy); the most frequent associated primary RT sites were the oropharynx (42.9%) and oral cavity (31.4%), and 76% of episodes occurred in the mandible. The diagnosis of ORN was confirmed in 18 participants for an incidence rate of 3.1% (18 of 572). Risk factors included pre-RT extractions (P = .008), a higher RT dose (P = .039), and tobacco use (P = .048). CONCLUSIONS: The 2-year incidence of exposed bone in the OraRad cohort was 6.1%; the incidence of confirmed ORN was 3.1%. Exposed bone after RT for HNC is relatively uncommon and, in most cases, is a short-term complication, not a recurring or persistent one.

Efficacy and safety of a novel mucoadhesive clobetasol patch for treatment of erosive oral lichen planus: A phase 2 randomized clinical trial.

BACKGROUND: Oral lichen planus (OLP) is a chronic inflammatory disorder of the oral mucosa. Currently there is no approved treatment for OLP. We report on the efficacy and safety of a novel mucoadhesive clobetasol patch (Rivelin® -CLO) for the treatment of OLP. METHODS: Patients with confirmed OLP and measurable symptomatic ulcer(s) participated in a randomized, double-blind, placebo-controlled, multicenter clinical trial testing a novel mucoadhesive clobetasol patch (Rivelin® -CLO) in OLP across Europe, Canada, and the United States. Patients were randomized to placebo (nonmedicated), 1, 5, 20 µg Clobetasol/patch, twice daily, for 4 weeks. The primary endpoint was change in total ulcer area compared to baseline. Secondary endpoints included improvement from baseline in pain, disease activity, and quality of life. RESULTS: Data were analyzed and expressed as mean [SD]. One hundred thirty-eight patients were included in the study; 99 females and 39 males, mean age was 61.1 [11.6] years. Statistical analyses revealed that treatment with 20-µg Rivelin® -CLO patches demonstrated significant improvement with ulcer area (p = 0.047), symptom severity (p = 0.001), disease activity (p = 0.022), pain (p = 0.012), and quality of life (p = 0.003) as compared with placebo. Improvement in OLP symptoms from beginning to the end of the study was reported as very much better (best rating) in the 20-µg group (25/32) patients compared to the placebo group (11/30), (p = 0.012). Adverse events were mild/moderate. Candidiasis incidence was low (2%). CONCLUSIONS: Rivelin® -CLO patches were superior to placebo demonstrating statistically significant, clinically relevant efficacy in objective and subjective improvement and, with a favorable safety profile.

Extraoral photobiomodulation for prevention of oral and oropharyngeal mucositis in head and neck cancer patients: interim analysis of a randomized, double-blind, clinical trial.

PURPOSE: To assess the safety and efficacy of prophylactic extraoral photobiomodulation (PBM) for the prevention of oral and oropharyngeal mucositis (OM) on clinical outcomes and survival in patients with oral cavity and oropharyngeal squamous cell carcinoma (OOPSCC). METHODS: OOPSCC patients who received radiotherapy (RT) were prospectively randomized to two groups: prophylactic extraoral PBM and placebo. OM grade (NCI), pain (VAS), analgesia, and anti-inflammatory prescriptions were assessed weekly. Quality of life questionnaires (QoL) were performed at the first and last day of RT. Following RT, participants were evaluated quarterly for oncological outcomes follow-up. RESULTS: Fifty-five patients met the inclusion criteria. The first occurrence of OM was observed at week 1, for the placebo group (p = 0.014). Later, OM onset and severity was observed for the PBM group, with first occurrence at week 2 (p = 0.009). No difference in severe OM incidence was observed (p > 0.05). Lower mean pain score was noted at week 7 for the PBM group (2.1) compared to placebo group (4.5) (p = 0.009). Less analgesics (week 3; p = 0.009/week 7; p = 0.02) and anti-inflammatory prescription (week 5; p = 0.0346) were observed for the PBM group. Better QoL scores were observed for the PBM group at last day of RT (p = 0.0034). No difference in overall survival among groups was observed in 1 year of follow-up (p = 0.889). CONCLUSION: Prophylactic extraoral PBM can delay OM onset, reduce pain, and reduce analgesic and anti-inflammatory prescription requirements. Extraoral PBM was associated with better QoL. There was no evidence of PBM impact on oncological outcomes. TRIAL REGISTRATION: TRN:RBR-4w4swx (date of registration: 01/20/2020).

Oral appliances in the management of neuropathic orofacial pain: A retrospective case series.

OBJECTIVE: Neuropathic orofacial pain disorders are frequently managed with topical or systemic medications that carry a risk of dangerous side effects such as drowsiness, disorientation, and/or physical addiction. The aim of this paper is to report the use of neurosensory oral appliances as a safe means of providing symptomatic relief for neuropathic orofacial pain. STUDY DESIGN: This is a retrospective chart review of patients with diagnoses of persistent idiopathic facial pain (PIFP), painful post-traumatic trigeminal neuropathy (PTTN), or an oral dysesthesia, who utilized neurosensory appliances with or without the use of topical anesthetic gel. RESULTS: Eleven patients were identified. Eight patients (62.5%) found benefit with the neurosensory appliance alone, and three patients (37.5%) found relief with the addition of lidocaine 2% gel. All patients reported >50% resolution of their symptoms, with three (37.5%) reporting complete resolution. Seven patients maintained follow-up ≥3 months, with efficacy lasting for a range of at least 3-8 months. CONCLUSION: Oral neurosensory appliances, whether used alone as a physical barrier or as a vehicle to deliver topical anesthetic, represent a safe and effective modality for the management of neuropathic orofacial pain disorders. Additional studies are needed to assess long-term efficacy.

Oral manifestations of immune-related adverse events in cancer patients treated with immune checkpoint inhibitors.

Immunotherapy with immune checkpoint inhibitors (ICIs) has transformed cancer treatment over the past decade, improving survival rates in numerous advanced cancers. Immune-related adverse events (irAEs) are common and can affect any organ system, with many of these toxicities being well-characterized with clear grading criteria and management approaches. There has been less emphasis on oral manifestations of irAEs. This review provides an overview of oral manifestations of irAEs, including mucosal and salivary gland toxicities, and proposes a grading system and management guidelines. irAEs are common treatment-related toxicities in patients treated with ICIs. Oral irAEs can range from asymptomatic white reticulations to life-threatening mucocutaneous reactions requiring aggressive management with corticosteroids and/or permanent discontinuation of ICIs. Oral healthcare providers should be prepared to identify and manage oral irAEs in collaboration with oncologists and other specialists.

Oral lichen planus: comparative efficacy and treatment costs-a systematic review.

OBJECTIVE: To compare the reported efficacy and costs of available interventions used for the management of oral lichen planus (OLP). MATERIALS AND METHODS: A systematic literature search was performed from database inception until March 2021 in MEDLINE via PubMed and the Cochrane library following PRISMA guidelines. Only randomized controlled trials (RCT) comparing an active intervention with placebo or different active interventions for OLP management were considered. RESULTS: Seventy (70) RCTs were included. The majority of evidence suggested efficacy of topical steroids (dexamethasone, clobetasol, fluocinonide, triamcinolone), topical calcineurin inhibitors (tacrolimus, pimecrolimus, cyclosporine), topical retinoids, intra-lesional triamcinolone, aloe-vera gel, photodynamic therapy, and low-level laser therapies for OLP management. Based on the estimated cost per month and evidence for efficacy and side-effects, topical steroids (fluocinonide > dexamethasone > clobetasol > triamcinolone) appear to be more cost-effective than topical calcineurin inhibitors (tacrolimus > pimecrolimus > cyclosporine) followed by intra-lesional triamcinolone. CONCLUSION: Of common treatment regimens for OLP, topical steroids appear to be the most economical and efficacious option followed by topical calcineurin inhibitors. Large-scale multi-modality, prospective trials in which head-to-head comparisons interventions are compared are required to definitely assess the cost-effectiveness of OLP treatments.

Patterns of oral mucositis in advanced oral squamous cell carcinoma patients managed with prophylactic photobiomodulation therapy-insights for future protocol development.

To characterize oral sites affected by radiation-induced oral mucositis (OM) and related clinical outcomes in oral cancer patients subjected to prophylactic photobiomodulation therapy (PBMT). This study included advanced oral squamous cell carcinoma (OSCC) patients treated with prophylactic PBMT for OM. The site distribution of OM, OM grading (CTCAE NCI, Version 4.0, 2010), OM-related pain (VAS), analgesic protocol (WHO Analgesic Ladder), and use of enteral nutrition were evaluated weekly during treatment. Data analysis was performed using descriptive statistics expressed as median values and percentages. A total of 145 OSCC patients were included. OM most frequently affected the lateral border of the tongue (44.1%), buccal mucosa (37.2%), and labial mucosa (33.8%). Keratinized oral mucosa sites, including the tongue dorsum (6.21%), retromolar trigone (8.3%), and hard palate (2.76%), were less frequently affected. Peak OM scores were observed at weeks 5, 6, and 7, with severe OM (NCI grades 3 and 4) rates of 11%, 20%, and 25%, respectively. The cumulative occurrence of severe OM was 23%, which developed as early as week 3 and as late as week 7. The highest mean value of OM-related pain (2.7) was observed at the sixth week, and 13.8% of the patients required feeding support. This study showed, compared with studies that did not provide PBMT, reduced severity of mucositis, reduced pain and analgesic use, and reduced tube feeding in patients treated with PBMT. OM involving keratinized and non-keratinized surfaces should be included in the prophylactic PBMT to reduce severe OM in future studies.

Long-Term Utilization Patterns of Topical Therapy and Clinical Outcomes of Oral Chronic Graft-versus-Host Disease.

An open-label phase 2 study of topical dexamethasone versus tacrolimus solutions in new-onset oral chronic graft-versus-host disease (cGVHD) revealed the superior efficacy of dexamethasone. The objective of this study was to report long-term patterns of topical therapy utilization and clinical outcomes in this cohort after completing the 30-day trial. A retrospective record review was performed from the date of study completion to January 2017. Topical therapies, systemic immunosuppressive therapies, objective measurements (National Institutes of Health severity score, oral mucosal scores), patient- reported outcomes (dryness, sensitivity, pain), and adverse events were recorded for oral cGVHD-related outpatient visits. Follow-up (FU) periods were defined as FU1 (0-1 month), FU2 (1-3 months), FU3 (3-6 months), FU4 (6-12 months), FU5 (12-18 months), and FU6 (18-24 months). Forty patients (52.5% males, median age, 56 years) completed the clinical trial and were included in the analysis. Topical therapies used were dexamethasone, tacrolimus, clobetasol, or a combination of these agents. At FU1, all 40 patients were receiving topical therapy, which decreased to 54.5% (12 out of 22) at FU6. Clinician-reported oral mucosal scores (0-12) and patient-reported sensitivity scores (0-10) decreased over time from FU1 (median mucosal score, 3; sensitivity, 3) to FU6 (mucosal score, 1; sensitivity, 2). Intralesional steroid therapy was provided to 6 patients for management of refractory oral ulcerations, all within the first year of follow-up. Patients with de novo symptomatic oral cGVHD may require long-term care with topical immunomodulatory therapy for up to 2 years, if not longer. Topical steroid and tacrolimus therapies are safe and effective in managing symptomatic oral cGVHD. Second-line topical therapy for refractory oral cGVHD requires further investigation.

Systematic review of natural and miscellaneous agents, for the management of oral mucositis in cancer patients and clinical practice guidelines - part 2: honey, herbal compounds, saliva stimulants, probiotics, and miscellaneous agents.

OBJECTIVE: To update the clinical practice guidelines for the management of oral mucositis (OM) that were developed by the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). This part focuses on honey, herbal compounds, saliva stimulants, probiotics, and miscellaneous agents. METHODS: A systematic review was conducted by the Mucositis Study Group of MASCC/ISOO. The body of evidence for each intervention, in each clinical setting, was assigned an evidence level. The findings were added to the database used to develop the 2014 MASCC/ISOO clinical practice guidelines. Based on the evidence level, one of the following guidelines were determined: Recommendation, Suggestion, No Guideline Possible. RESULTS: A total of 78 papers were identified within the scope of this section, of which 49 were included in this review and merged with nine publications that were reported in the previous guidelines update. A new Suggestion was made for honey (combined topical and systemic delivery) for the prevention of OM in head and neck cancer patients receiving radiotherapy with or without chemotherapy. A new Suggestion clarified that chewing gum is not effective for the prevention of OM in pediatric patients with hematological or solid cancer treated with chemotherapy. No guideline was possible for other interventions. CONCLUSIONS: Numerous natural products and herbal remedies were studied for the management of OM. Of the agents reviewed in this systematic review, a guideline in favor was made for honey (combined topical and systemic), while a guideline against was made for chewing gum. Additional research is warranted to clarify the potential of other interventions.

Oral immune-related adverse events associated with PD-1 inhibitor therapy: A case series.

OBJECTIVE: The aim of this study was to characterize clinical and histopathological features, and management outcomes of patients with oral immune-related adverse events (irAEs) secondary to programmed cell death-1 (PD-1) inhibitors. METHODS: This was a case series of cancer patients receiving PD-1 inhibitor therapy who were referred to oral medicine for the development of oral irAEs. Demographic, clinical, and histopathological data were collected from electronic medical records. RESULTS: There were 13 patients (7 males) with a median age of 68 years (range: 39-82) who were treated with nivolumab (n = 7) or pembrolizumab (n = 6). Oral irAEs included lichenoid lesions (n = 10), erythema multiforme (EM) (n = 2), and acute graft-versus-host disease reactivation (n = 1), with or without ulcerations (n = 8). Four patients (31%) presented with only oral irAEs. Oral biopsies showed lichenoid mucositis (n = 4). Management with topical and systemic steroids led to complete symptomatic response in most patients (n = 12). PD-1 inhibitor therapy was temporarily discontinued (n = 3) and discontinued indefinitely (n = 2) due to severe oral irAEs. CONCLUSION: Patients receiving PD-1 inhibitors may develop oral irAEs characterized by lichenoid lesions, ulcers, or EM. Topical and systemic steroids appear to be effective in managing oral lesions although the severity of irAEs may necessitate PD-1 inhibitor therapy dose modification.

Preoperative dental screening prior to cardiac valve surgery and 90-day postoperative mortality.

BACKGROUND: Preoperative dental screening before cardiac valve surgery is widely accepted but its required scope remains unclear. This study evaluates two preoperative dental screening (PDS) approaches, a focused approach (FocA) and a comprehensive approach (CompA), to compare postsurgical 90-day mortality. METHODS: Retrospective cohort analysis was performed on all patients who underwent valve surgery at Brigham and Women's Hospital with FocA and Massachusetts General Hospital with CompA of PDS approach from January 2009 to December 2016. Patients with intravenous drug abuse and systemic infections were excluded. Univariate, multivariable, and subgroup analysis was performed. RESULTS: A total of 1835 patients were included in the study. With FocA 96% of patients (1097/1143) received dental clearance in a single encounter with 3.3% receiving radiographs and undergoing dental extractions. With CompA 35.5% of patients (245/692) received dental clearance in a single encounter, 94.2% received radiographs, and 21.8% underwent dental extractions. There was no significant difference in 90-day mortality when comparing both PDS approach (10% vs 8.4%, P = .257). This remained unchanged in a multivariable model after adjusting for risk factors (odds ratio:1.32 [95%CI:0.91-1.93] [P = .14]). Reoperation due to infection was less in FocA (0.5%) vs CompA (2.6) (P < .001) and postoperative septicemia was increased in the FocA (1.7%) cohort when compared to the CompA (0.7%) (P < .001) patients. CONCLUSIONS: There was no difference in post valve surgery 90-day mortality between patients who underwent a FocA vs CompA of PDS.

Evaluation of a community-based dental screening program prior to radiotherapy for head and neck cancer: a single-center experience.

PURPOSE: Oral toxicities following radiation therapy (RT) for head and neck (HN) cancer can be profound and are associated with poor health outcomes. The Division of Oral Medicine and Dentistry at Brigham and Women's Hospital and Dana-Farber Cancer Institute therefore implemented a dental evaluation program designed for community-based (CB) dentists to evaluate and treat patients scheduled for HN RT. The aim of this retrospective single-center cohort study was to assess the compliance of CB dentists with this pre-RT dental evaluation program. METHODS: A retrospective analysis of dental evaluations completed by CB dentists from December 2013 to December 2015 was performed. Descriptive statistics were used to determine compliance. RESULTS: A total of 186 dental evaluations were received. Compliance with completion of dental treatment was as follows: scaling and prophylaxis: 94.5% (172/182); dental restorations: 78.7% (48/61); endodontic therapy: 76.9% (10/13); and dental extractions: 76.9% (30/39). Compliance of CB dentists with all requested components of the pre-RT evaluation and treatment was 77.4% (144/186). The median distance traveled by patients to the CB dentist and to the hospital was 5.2 miles (range 0.03-66.0) and 46.5 miles (range 0.8-1457; p < 0.01), respectively. CONCLUSION: In this study, the majority of patients completed their necessary dental treatment in a timely manner by their CB dentist in collaboration with an oral medicine specialist. Given the high compliance of CB dentists, this program could serve as a model for other cancer centers to optimize oral and dental health prior to RT.

Systematic review of natural and miscellaneous agents for the management of oral mucositis in cancer patients and clinical practice guidelines-part 1: vitamins, minerals, and nutritional supplements.

PURPOSE: To update the clinical practice guidelines for the use of natural and miscellaneous agents for the prevention and/or treatment of oral mucositis (OM). METHODS: A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer / International Society of Oral Oncology (MASCC/ISOO). The body of evidence for each intervention, in each cancer treatment setting, was assigned an evidence level. The findings were added to the database used to develop the 2014 MASCC/ISOO clinical practice guidelines. Based on the evidence level, the following guidelines were determined: Recommendation, Suggestion, and No Guideline Possible. RESULTS: A total of 78 papers were identified within the scope of this section, out of which 29 were included in this part, and were analyzed with 27 previously reviewed studies. A new Suggestion was made for oral glutamine for the prevention of OM in head and neck (H&N) cancer patients receiving radiotherapy with concomitant chemotherapy. The previous Recommendation against the use of parenteral glutamine for the prevention of OM in hematopoietic stem cell transplantation (HSCT) patients was re-established. A previous Suggestion for zinc to prevent OM in H&N cancer patients treated with radiotherapy or chemo-radiotherapy was reversed to No Guideline Possible. No guideline was possible for other interventions. CONCLUSIONS: Of the vitamins, minerals, and nutritional supplements studied for the management of OM, the evidence supports a Recommendation against parenteral glutamine in HSCT patients and a Suggestion in favor of oral glutamine in H&N cancer patients for the management of OM.
