RESUMEN
OBJECTIVE: To assess the clinical scenarios in which nerve blocks are employed in the context of burning mouth syndrome (BMS). STUDY DESIGN: This scoping review followed the PRISMA-ScR. A protocol was generated on Open Science Framework. Electronic searches were performed in the following databases: PubMed, Scopus, EMBASE, Web of Science, LILACS, and Cochrane, in addition to the grey literature and citations from Grémeau-Richard et al. (2010). RESULTS: Nerve blocks were used for treatment purposes in all cases. The mandibular nerve and the stellate ganglion were both blocked in 50% studies, while the maxillary nerve and lingual nerve were blocked in 25% study each. The anesthetics used were lidocaine (50%) and bupivacaine (50%). Relief was generally reported after immediate block, and at a mean follow-up of 4.5 weeks, there was considerable improvement compared to the initial conditions when the mandibular and/or maxillary nerve were targeted. CONCLUSIONS: The use of nerve blocks has been employed in the treatment of patients with refractory BMS. Clinical studies with standardized methodology are necessary to validate and understand the potential role of mandibular and maxillary nerve block in this setting.
RESUMEN
OBJECTIVE: To compare salivary flow rates between females and males, before and after radiation therapy (RT) for head and neck cancer (HNC). METHODS: Prospective observational multicenter cohort study (OraRad). Stimulated whole salivary flow was measured before RT and at 6 and 18 months after RT. RESULTS: Mean (95% confidence interval) salivary flow in g/min before RT was 0.81 (0.71, 0.90) in females (n = 107) and 1.20 (1.15, 1.25) in males (n = 391) (p < 0.001); at 6 months was 0.34 (0.24, 0.44) in females and 0.50 (0.44, 0.55) in males (p = 0.01); at 18 months was 0.49 (0.38, 0.59) in females and 0.70 (0.64, 0.75) in males (p < 0.001). Median nadir salivary flow after RT was 0.22 in females and 0.35 in males (p < 0.001). A lower nadir salivary flow in females, but not males, was associated with an increased risk for tooth failure (p = 0.02). CONCLUSIONS: Females with HNC have lower stimulated whole salivary flow than males, before and after RT. Low salivary flow after RT may be a risk factor for tooth failure among females. The lower pre-RT salivary flow rates in females, combined with prior literature in other populations, indicates that, in general, females have lower stimulated salivary flow than males.
RESUMEN
OBJECTIVES: We aimed to assess the effectiveness of the use of topical imiquimod for the management of oral leukoplakia (OL). METHODS: This was a retrospective study. Medical chart reviews were conducted to identify patients with biopsy-proven OL treated with topical 5% imiquimod. Data included OL characteristics, histopathological diagnosis, treatment outcome, and adverse events (AEs). Treatment response was assessed by measuring the percentage reduction in the size of OL lesions. RESULTS: 33 patients (51.5% females; median age: 65 years) with 38 lesions were included. OLs were either localized (23.7%) or multifocal lesions (76.3%), with the majority on the gingiva (86.8%). Pretreatment histopathological diagnoses were dysplasia in 84.2% and nonreactive hyperkeratosis in 15.8%. Most regimens consisted of 60-minute applications, 5-days-a-week, for 6 weeks. At the end of treatment, 81.6% of 38 lesions showed a reduction in size with 68.4% exhibiting ≥50% reduction in size, and 42.1% exhibiting complete resolution. Application site reactions were the most common with pain/soreness/sensitivity occurring in 86.8%. Fatigue was the most frequently reported systemic AE (28.9%). CONCLUSION: Two-thirds of OL lesions had ≥50% reduction in size. Most AEs were temporary and resolved upon treatment discontinuation. Prospective studies are needed to further assess Imiquimod's effectiveness in OL management.
RESUMEN
PURPOSE: A MASCC/ISOO Clinical Practice Statement (CPS) is aimed at generating a concise tool for clinicians that concentrates practical information needed for the management of oral complications of cancer patients. This CPS is focused on the risk of secondary oral cancer following hematopoietic cell transplantation (HCT). METHODS: This CPS was developed based on critical evaluation of the literature followed by a structured discussion of a group of leading experts, members of the Oral Care Study Group of MASCC/ISOO. The information is presented in the form of succinct bullets to generate a short manual about the best standard of care. RESULTS: Studies described a 7-16-fold higher risk of secondary oral cancer (mainly squamous cell carcinoma) in allogeneic HCT (alloHCT) recipients, particularly in those who developed chronic graft versus host disease (cGVHD). Risk increases over time and is influenced by several risk factors. In autologous HCT, oral cancer risk seemed only slightly elevated. CONCLUSION: Clinicians should be aware of the higher oral cancer risk in alloHCT survivors, and emphasize the importance of lifelong oral cancer surveillance (at least every 6-12 months) and avoiding cancer promoting lifestyle factors in an empathic way, particularly of those with (a history of) cGVHD. Post-HCT for Fanconi anemia or dyskeratosis congenita, education and rigorous follow-up is even more crucial. In case of suspected oral lesions in the presence of oral mucosal cGVHD, a GVHD intervention may facilitate diagnosis. Suspected lesions should be biopsied. More research is needed on the role of HPV in oral cancer post-HCT.

PURPOSE: A MASCC/ISOO Clinical Practice Statement (CPS) is aimed at generating a concise tool for clinicians, which concentrates on practical information needed for the management of oral complications of cancer patients. This CPS is focused on the current understanding of controversies that may arise while providing basic oral care in hemato-oncology patients and hematopoietic cell transplantation recipients (HCT). The CPS will summarize and elucidate controversies that have appeared in the literature and professional discussions. METHODS: This CPS was developed based on a critical evaluation of the literature followed by a structured discussion of a group of leading experts, members of the Oral Care Study Group of MASCC/ISOO. The information is presented in the form of succinct bullets to generate a short manual about the best standard of care. RESULTS: Controversies about the use of chlorhexidine (CHX) oral rinse, mechanical dental plaque removal procedures, the need for toothbrush replacement during phases of low blood cell counts, and the use of lidocaine mouthwash for oral pain were identified and discussed. Consensus about the best standard of care was outlined. CONCLUSION: The following ratifications are applicable for oral care in hemato-oncology patients and patients undergoing HCT: (1) CHX may reduce the risk of oral infections, although it was not found to reduce the risk of oral mucositis. (2) Toothbrushing and proficient interproximal cleaning should not be discouraged during HCT. (3) Toothbrushes do not need to be replaced daily and are preferred over cleansing swabs. (4) Lidocaine rinse, swish and spit, may be considered to palliate oral mucosal pain if applied in a certain manner.

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.
RESUMEN
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.
RESUMEN
BACKGROUND: Patients who are oral hygiene noncompliant (OHNC) are more likely to lose teeth after radiation therapy (RT) for head and neck cancer (HNC), which increases the risk of developing osteoradionecrosis. A previous study revealed that patients who were OHNC at baseline (BL) who became oral hygiene compliant during follow-up had the best tooth-failure outcomes. The purpose of this study was to identify factors associated with oral hygiene compliance (OHC), overall, and among those who were BL OHNC. METHODS: This was an observational, prospective, cohort study of 518 patients with HNC assessed before RT and at post-RT follow-up visits every 6 months for 2 years. Patient and treatment-related information was collected at BL and during follow-up, including self-reported OHC. OHC was defined as toothbrushing at least twice daily and flossing at least once daily. RESULTS: Of the 296 patients who self-reported being BL OHNC, 44 (14.9%) became oral hygiene compliant at all follow-up visits. Among this group, those who had dental insurance (P = .026), surgery before RT (P = .008), limited mouth opening before RT (P = .001), compliant fluoride use (P = .023), primary RT site of oral cavity (P = .004), and primary surgical site of larynx and hypopharynx (P = .042) were more likely to become oral hygiene compliant post-RT. CONCLUSIONS: The reasons for the cohort of patients with HNC in this study being OHNC are multifaceted and relate to socioeconomic factors and cancer characteristics. PRACTICAL IMPLICATIONS: Finding ways to increase OHC and fluoride use among patients with HNC who are at greatest risk of being OHNC should be explored.

BACKGROUND: Thalidomide has anti-inflammatory properties and has been used off-label for multiple mucocutaneous disorders, but its application in managing refractory oral mucosal diseases is unclear. This study aimed to review the efficacy and safety of thalidomide in treating various oral mucosal disorders refractory to conventional therapies. METHODS: The medical records of patients who were prescribed thalidomide from 2002 through 2021 for oral mucosal disorders were reviewed. Data collected included demographic characteristics, oral mucosal disease diagnosis, treatment courses, and thalidomide dose, duration, response, and side effects. RESULTS: Thalidomide was prescribed for 28 patients with diagnoses of recurrent aphthous stomatitis (n = 14), inflammatory oral lichenoid lesions (n = 6), traumatic ulcerative granuloma with stroma eosinophilia (n = 5), chronic radiation-induced mucositis (n = 2), and orofacial granulomatosis (n = 1). Patients were treated for a median duration of 84 days (range 2-1,582). Clinical improvement was observed in 19 of 22 patients who completed at least 1 cycle of thalidomide (86.4%), with complete resolution in 12 patients (54.5%). Adverse events occurred in 75% of patients (n = 21), with 8 requiring thalidomide discontinuation. The most common adverse events included peripheral neuropathy (42.9%), drowsiness (28.6%), and constipation (21.4%). CONCLUSIONS: Thalidomide may be considered for the management of refractory oral mucosal disorders. Drug side effects are common and need monitoring closely during use.

OBJECTIVE: Trismus/reduced mouth opening (RMO) is a common side effect of radiotherapy (RT) for head and neck cancer (HNC). The objective was to measure RMO, identify risk factors for RMO, and determine its impact on quality of life (QOL). STUDY DESIGN: OraRad is an observational, prospective, multicenter cohort study of patients receiving curative intent RT for HNC. Interincisal mouth opening measurements (n = 565) and patient-reported outcomes were recorded before RT and every 6 months for 2 years. Linear mixed-effects models were used to evaluate change in mouth opening and assess the relationship between trismus history and change in QOL measures. RESULTS: Interincisal distance decreased from a mean (SE) of 45.1 (0.42) mm at baseline to 42.2 (0.44) at 6 months, with slight recovery at 18 months (43.3, 0.46 mm) but no additional improvement by 24 months. The odds of trismus (opening <35 mm) were significantly higher at 6 months (odds ratio [OR] = 2.21, 95% CI: 1.30 to 3.76) and 12 months (OR = 1.87, 95% CI: 1.08 to 3.25) compared with baseline. Females were more likely to experience trismus at baseline and during follow-up (P < .01). Patients with oral cavity cancer had the highest risk for trismus at baseline and post-RT (P < .01). RMO was associated with higher RT dose to the primary site and receiving concomitant chemotherapy (P < .01). Trismus was associated with self-reported difficulty opening the mouth and dry mouth (P < .01). CONCLUSIONS: A decrease in mouth opening is a common treatment-related toxicity after RT, with some recovery by 18 months. Trismus has a significant impact on survivor QOL.

OBJECTIVE: The objective of this study is to describe the efficacy of hydroxychloroquine (HCQ) in patients with oral lichen planus (OLP) refractory to conventional therapy. STUDY DESIGN: In this single-center retrospective study, patients were prescribed HCQ 200 mg twice daily. Pain, reticulation, erythema, and ulceration scores were recorded. Two-sample and paired t tests were used to evaluate mean and paired pain scores and paired t test to determine substantial differences in paired REU scores, at HCQ initiation visit and final follow-up at 12 to 24 months. RESULTS: Thirty-six patients (69.4% female) with a median age of 70 ± 12.0 (range 48-99) were initiated on HCQ. Only 30 patients were evaluable because pruritus developed in 5 patients (13.9%) and gastrointestinal symptoms in 1 (2.8%). The mean follow-up was 23.2 months (range 1-74). In 19 patients, there was a significant decline in the worst pain score from a mean of 3.9 (SD± 2.8, nâ¯=â¯19) to 1.9 (SD ± 2.4, nâ¯=â¯19) (tâ¯=â¯2.837, P < .006). Paired reticulation, erythema, and ulceration (REU scores) decreased from a weighted mean score of 16.0 (SD ± 8.0, nâ¯=â¯12) to 12.0 (SD ± 6.3, nâ¯=â¯12) (tâ¯=â¯2.07, P < .032). CONCLUSION: Hydroxychloroquine was a suitable option and effective in reducing symptoms and disease severity in patients with recalcitrant OLP who do not adequately respond to standard therapy.

Importance: Proliferative verrucous leukoplakia (PVL) is an aggressive oral precancerous disease characterized by a high risk of transformation to invasive oral squamous cell carcinoma (OSCC), and no therapies have been shown to affect its natural history. A recent study of the PVL immune landscape revealed a cytotoxic T-cell-rich microenvironment, providing strong rationale to investigate immune checkpoint therapy. Objective: To determine the safety and clinical activity of anti-programmed cell death 1 protein (PD-1) therapy to treat high-risk PVL. Design, Setting, and Participants: This nonrandomized, open-label, phase 2 clinical trial was conducted from January 2019 to December 2021 at a single academic medical center; median (range) follow-up was 21.1 (5.4-43.6) months. Participants were a population-based sample of patients with PVL (multifocal, contiguous, or a single lesion ≥4 cm with any degree of dysplasia). Intervention: Patients underwent pretreatment biopsy (1-3 sites) and then received 4 doses of nivolumab (480 mg intravenously) every 28 days, followed by rebiopsy and intraoral photographs at each visit. Main Outcomes and Measures: The primary end point was the change in composite score (size and degree of dysplasia) from before to after treatment (major response [MR]: >80% decrease in score; partial response: 40%-80% decrease). Secondary analyses included immune-related adverse events, cancer-free survival (CFS), PD-1 ligand 1 (PD-L1) expression, 9p21.3 deletion, and other exploratory immunologic and genomic associations of response. Results: A total of 33 patients were enrolled (median [range] age, 63 [32-80] years; 18 [55%] were female), including 8 (24%) with previously resected early-stage OSCC. Twelve patients (36%) (95% CI, 20.4%-54.8%) had a response by composite score (3 MRs [9%]), 4 had progressive disease (>10% composite score increase, or cancer). Nine patients (27%) developed OSCC during the trial, with a 2-year CFS of 73% (95% CI, 53%-86%). Two patients (6%) discontinued because of toxic effects; 7 (21%) experienced grade 3 to 4 immune-related adverse events. PD-L1 combined positive scores were not associated with response or CFS. Of 20 whole-exome sequenced patients, all 6 patients who had progression to OSCC after nivolumab treatment exhibited 9p21.3 somatic copy-number loss on pretreatment biopsy, while only 4 of the 14 patients (29%) who did not develop OSCC had 9p21.3 loss. Conclusions and Relevance: This immune checkpoint therapy precancer nonrandomized clinical trial met its prespecified response end point, suggesting potential clinical activity for nivolumab in high-risk PVL. Findings identified immunogenomic associations to inform future trials in this precancerous disease with unmet medical need that has been difficult to study. Trial Registration: ClinicalTrials.gov Identifier: NCT03692325.

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.

Photobiomodulation therapy (PBMT) is recommended for prevention and treatment of oral mucositis, a painful condition that occurs in cancer patients. Intraoral PBMT is limited to treating distal oral mucosa and oropharynx. Extraoral PBMT may provide a more efficient intervention. The goal of this study was to develop a clinically viable protocol for extraoral PBMT. Monte Carlo modeling was used to predict the distribution of 850 nm light for four treatment sites, using anatomical data obtained from MRI and optical properties from the literature. Simulated incident light power density was limited to 399 mW/cm2 to ensure treatment safety and to prevent tissue temperature increase. The results reveal that total tissue thickness determines fluence rate at the oral mucosa, whereas the thickness of individual tissue layers and melanin content are of minor importance. Due to anatomical differences, the fluence rate varied greatly among patients. Despite these variations, a universal protocol was established using a median treatment time methodology. The determined median treatment times required to deliver efficacious dose between 1 and 6 J/cm2 were within 15 min. The developed PBMT protocol can be further refined using the combination of pretreatment imaging and the Monte Carlo simulation approach implemented in this study.

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.
RESUMEN
BACKGROUND: The objective of this study was to identify tooth-level risk factors for use during preradiation dental care management to predict risk of tooth failure (tooth lost or declared hopeless) and exposed bone after radiation therapy (RT) for head and neck cancer (HNC). METHODS: The authors conducted a prospective observational multicenter cohort study of 572 patients receiving RT for HNC. Participants were examined by calibrated examiners before RT and then every 6 months until 2 years after RT. Analyses considered time to tooth failure and chance of exposed bone at a tooth location. RESULTS: The following pre-RT characteristics predicted tooth failure within 2 years after RT: hopeless teeth not extracted pre-RT (hazard ratio [HR], 17.1; P < .0001), untreated caries (HR, 5.0; P < .0001), periodontal pocket 6 mm or greater (HR, 3.4; P = .001) or equaling 5 mm (HR, 2.2; P = .006), recession over 2 mm (HR, 2.8; P = .002), furcation score of 2 (HR, 3.3; P = .003), and any mobility (HR, 2.2; P = .008). The following pre-RT characteristics predicted occurrence of exposed bone at a tooth location: hopeless teeth not extracted before RT (risk ratio [RR], 18.7; P = .0002) and pocket depth 6 mm or greater (RR, 5.4; P = .003) or equaling 5 mm (RR, 4.7; P = .016). Participants with exposed bone at the site of a pre-RT dental extraction averaged 19.6 days between extraction and start of RT compared with 26.2 days for participants without exposed bone (P = .21). CONCLUSIONS: Individual teeth with the risk factors identified in this study should be considered for extraction before RT for HNC, with adequate healing time before start of RT. PRACTICAL IMPLICATIONS: The findings of this trial will facilitate evidence-based dental management of the care of patients receiving RT for HNC. This clinical trial was registered at Clinicaltrials.gov. The registration number is NCT02057510.

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.

INTRODUCTION: The oral cavity is one of the most common sites impacted by hematopoietic stem cell transplantation (HSCT) with acute complications including mucositis, bleeding, salivary gland dysfunction, infection, and taste alteration. These complications may result in significant morbidity and can negatively impact outcomes such as length of stay and overall costs. As such, oral care during HSCT for prevention and management of oral toxicities is a standard component of transplant protocols at all centers. The objective of this study was to evaluate the current oral care practices for patients during HSCT at different transplant centers within the Eastern Mediterranean region. MATERIAL AND METHODS: An internet-based survey was directed to 30 transplant centers in the Eastern Mediterranean region. The survey included five sections asking questions related to (1) transplant center demographics; (2) current oral care protocol used at the center and type of collaboration (if any) with a dental service; (3) use of standardized oral assessment tools and grading systems for mucositis; (4) consultations for management of oral complications; and (5) oral health needs at each center. Data are presented as averages and percentages. RESULTS: A total of 16 responses from 11 countries were collected and analyzed, indicating a response rate of 53%. Eight centers reported that a dentist was part of the HSCT team, with four reporting oral medicine specialists specifically being part of the team. Almost all centers (15/16; 93%) had an affiliated dental service to facilitate pre-HSCT dental clearance with an established dental clearance protocol at 14 centers (87%). Dental extraction was associated with the highest concern for bleeding and the need for platelet transfusion. With respect to infection risk, antibiotic prophylaxis was considered in the setting of low neutrophil counts with restorative dentistry and extraction. All centers provide daily reinforcement of oral hygiene regimen. The most frequently used mouth oral rinses included sodium bicarbonate (68%) and chlorhexidine gluconate (62%), in addition to ice chips for dry mouth (62%). The most frequently used mucositis assessment tools were the World Health Organization scale (7/16; 43%) and visual analogue scale for pain (6/16; 37%). Mucositis pain was managed with lidocaine solution (68.8%), magic mouth wash (68.8%) and/or systemic pain medications (75%). CONCLUSIONS: Scope and implementation of oral care protocols prior to and during HSCT varied between transplant centers. The lack of a universal protocol may contribute to gaps in oral healthcare needs and management for this group of patients. Further dissemination of and education around available oral care guidelines is warranted. CLINICAL RELEVANCE: Considering oral care during HSCT a standard component of transplant protocols, the current study highlights the common oral care practices for patients at centers within the Eastern Mediterranean region.

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.
