Abstract
Oral mucositis (OM) is one of the common adverse events associated with cancer treatment that decreases the quality of life and affects treatment outcomes. However, the medications used to manage OM are generally only palliative, and our knowledge of the syndrome is limited. The etiology of the syndrome is thought to be complex and multifactorial. We investigated the trends and characteristics of OM and estimated molecular initiating events (MIEs) associated with the development of the syndrome using the FDA Adverse Event Reporting System. The study of trends and characteristics suggested that OM is significantly more likely to occur in females and nonelderly patients and is likely to be induced by protein kinase inhibitors such as afatinib and everolimus. Next, we used Toxicity Predictor, an in-house quantitative structure-activity relationship system, to estimate OM-associated MIEs. The results revealed that the agonist activity of the human pregnane X receptor, thyroid-stimulating hormone-releasing hormone receptor, and androgen receptor may be associated with OM development. Our study findings are expected to help avoid the risk of OM induction during the drug discovery process and clinical use of antineoplastic agents.

Wang J, Gu L, Zhi C, Yang S. Risk factor and prediction model development for severe radiation-induced oral mucositis in head and neck tumors. Future Oncol 2024:1-11. [PMID: 39105623 DOI: 10.1080/14796694.2024.2384353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Accepted: 07/22/2024] [Indexed: 08/07/2024] Open
Abstract
Aim: This article aims to identify risk factors for severe radiation-induced oral mucositis (RIOM) in head and neck cancer (HNC) patients. In addition, we intend to establish a predictive model in patients undergoing intensity-modulated radiotherapy. Patients & methods: In this retrospective study, several HNC patients (n = 179) treated at Zhejiang Provincial People's Hospital from January 2019 to June 2023 were considered. The recruited subjects were divided into modeling and validation groups. The experimental data on clinical characteristics and treatment were collected and analyzed to identify predictive factors for severe RIOM based on the logistic regression approach. Results: The results indicated that severe RIOM occurred in 55.3% of patients. Accordingly, significant predictors included smoking history, diabetes, concurrent chemotherapy, cumulative radiation dose and weight loss of ≥5% in relative to admission weight. A nomogram based on these factors was validated, showing excellent predictive accuracy. Conclusion: In summary, the predictive model could effectively identify high-risk patients for severe RIOM, enabling the design of targeted interventions and improving patient management during radiotherapy.

Abstract
This study aimed to investigate the relationship between epigenetic mechanisms and oral mucositis (OM) in paediatric patients with acute lymphoblastic leukaemia. Oral cells were collected from 76 participants, including 15 healthy individuals, 10 patients with acute lymphoblastic leukaemia but without a history of OM and 51 acute lymphoblastic leukaemia patients with a history of OM (35 with active OM and 16 who had recovered from OM). Global DNA methylation in the miR-9-1 and miR-9-3 genes was performed. Seven polymorphisms rs1801131, rs1801133 (MTHFR), rs2228611 (DNMT1), rs7590760, rs1550117 (DNMT3A), rs6087990, rs2424913 (DNMT3B) were genotyped and an analysis of association with global DNA methylation was performed. The global methylation levels were lower in cancer patients recovered from OM than in the other groups. A higher frequency of unmethylated profile for miR-9-1 and partially methylated profile for miR-9-3 was observed in cancer patients regardless of OM history compared to healthy patients. The GG genotype of the rs2228611 (DNMT1) polymorphism was associated with higher levels of global methylation in cancer patients irrespective of OM. It was concluded that global methylation is associated with mucosal recovery. The effect of DNMT1 genotype on the global DNA methylation profile, as well as the methylation profile of miR-9-1 and miR-9-3 in cancer patients is independent of OM.

A retrospective analysis in patients with head and neck carcinoma. Support Care Cancer 2024; 32:508. [PMID: 38992294 DOI: 10.1007/s00520-024-08724-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 07/05/2024] [Indexed: 07/13/2024]
Abstract
PURPOSE Considering the tumor in the oral cavity or the oropharynx and nasopharynx region might be an aggravating factor for oral mucositis (OM) manifestation, the present study aimed to evaluate whether the location of the tumor and the use of photobiomodulation therapy (PBMT) might affect the frequency of oral candidiasis (OC) during radiotherapy (RT) and/or chemotherapy (CT) treatments. METHODS The medial records of seventy-four patients with head and neck cancer treated in a public service from 2016 to 2019 were evaluated. All these patients were submitted to RT in an accumulated dose of 48 to 70 Gy of radiation. Data about OM and OC were collected and presented according to the application of a therapeutic protocol with laser photobiomodulation (PBMT) to control oral mucositis, or not (No-PBM), and the location of tumor (head and neck or oral cavity). In the PBMT group patients, a low-power laser device composed of InGaAlP diode (maximum output power of 86.7 mW, active tip area of 0.1256 cm2, and continuous wavelength of 660 nm), was applied to the lips (three points each), right and left jugal mucosa (three points each), the limit between hard and soft palate (three points), buccal floor/sublingual gland (one point), lateral edge of the tongue (three points on each side), and back of the tongue (six points), three times weekly, for 5 weeks. The dosimetry used in each application was 2 J for 3 s, thus totaling 56 J. The correlation between clinical characteristics such as age, tumor size (T), metastatic lymph node (N), number of RT and CT sessions, candidiasis, and OM were analyzed. RESULTS Mucositis grades 1 and 2 were the most common among all patients, especially before the 12th radiotherapy session, regardless of the treatment with PBM (p > 0.05). Additionally, no difference in the grade of OM and OC was significantly observed when comparing the two laser therapy groups. OC was more frequent after the 12th radiotherapy session in all groups. Nonetheless, OM and OC had a different correlation regarding to tumor location (head and neck and oral cavity) being PBMT a positive therapy to delay OM. It was observed a positive and statistically significant correlation between tumors at oral cavity and OM, regardless PBMT (R = 0.84, p < 0.05 to PBMT and R = 0.13, p < 0.05 to No-PBM). Otherwise, OC was positively correlated to local metastasis in patients with oral tumors undergoing PBMT (R = 0.84, p < 0.05). CONCLUSION Patients with oral cavity tumor presented more OM, especially high grades, then patients with tumors in other regions of the head and neck, which seems to be related to the irradiation parameters of radiotherapy and/or with the limitation of conduction of PBMT in tumor areas. OM and OC were not changed by PBMT, although it helped to reduce the incidence of severe cases of OM.

Abstract
Oral mucositis (OM) is a common and debilitating toxicity of cancer treatments - chemotherapy, radiotherapy, hematopoietic cell transplant, or combinations. OM is associated with severe oral pain and has negative impacts on patient function and quality of life. Additionally, OM has accompanying systemic complications that may have critical implications. These local and systemic consequences can alter cancer treatment, and add an economic burden. This review covers the clinical presentation and course of OM, differential diagnosis, clinical and economic impacts, pathogenesis, risk factors, assessment measures, biomarkers and prediction of OM, management, research advances in the development of new drugs and treatments, and big data.

Unravelling Quality of Life for Head and Neck Cancer Patients after VMAT Radiation Therapy: Insights from Toxicity, Dosimetry and Symptoms Correlation. Clin Pract 2024; 14:1085-1099. [PMID: 38921264 PMCID: PMC11202948 DOI: 10.3390/clinpract14030086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 05/23/2024] [Accepted: 05/29/2024] [Indexed: 06/27/2024] Open
Abstract
(1) Background: Head and neck cancer treatment, including advanced techniques like Volumetric Modulated Arc Therapy (VMAT), presents challenges for maintaining patient quality of life (QoL). Thus, thoroughly investigating how radiation therapy (RT) affects patients has been proved essential. Derived by that, this study aims to understand the complex interactions between not only RT and QoL but also symptom severity, and treatment-related toxicities in three distinct time points of patient's treatment; (2) Methods: To achieve that, EORTC-QLQ-C30 and EORTC QLQ-H&N35 questionnaires were used in combination with EORTC_RTOG scoring criteria and Spearman's rho statistical analysis for 74 patients with cancer undergoing VMAT radiation therapy; (3) Results: The results revealed a significant improvement in the Overall Health Index post-treatment, indicating a temporary decline during therapy followed by subsequent recovery, often surpassing pre-treatment QoL levels. Concurrently a reduction in symptomatology was observed, notably in pain, swallowing difficulties, and dry mouth, aligning with prior research indicating decreased symptom burden post-treatment. However, Spearman's correlation coefficient analysis at two distinct time points during therapy uncovered varying degrees of correlation between dosimetric data at Organs at Risk (OARs) and reported symptoms, highlighting potential limitations in using QoL questionnaires as sole indicators of treatment efficacy. Our investigation into the correlation between dosimetric data, toxicity, and symptoms focused on the relationship between radiation doses and oral mucositis levels, a common toxicity in head and neck cancer patients. Significant associations were identified between toxicity levels and dosimetric parameters, particularly with OARs such as the parotid glands, oral cavity, and swallowing muscles, underlining the utility of the EORTC method as a reliable toxicity assessment tool; (4) Conclusions: To summarize, current research attempts to underscore the importance of refining QoL assessments for enhanced patient care. The integration of dosimetric data, symptom severity, and treatment-related toxicities in the QoL outcomes of head and neck cancer patients undergoing VMAT radiation therapy, can lead towards the optimization of treatment strategies and the improvement of patient outcomes in future patient-centered radiation therapy practices.

Abstract
BACKGROUND Chemotherapy is a common treatment for cancer, but it is associated with adverse drug reactions like oral mucositis. This condition destroys basal cells in the oral mucosal layer, causing inflammation and ulceration. This can impact the patient's physical, emotional, and psychological well-being, affecting treatment outcomes and quality of life. This study aims to determine the prevalence, severity, and risk factors of chemotherapy-induced oral mucositis among adult cancer patients. METHODS The study was a cross-sectional study conducted among adult cancer patients receiving chemotherapy at the cancer unit of Mbarara Regional Referral Hospital in southwestern Uganda. Data was collected through patient interviews, oral examinations, and patient chart reviews. RESULTS Out of 268 patients, 115 (42.9%) experienced oral mucositis. Grade 2 oral mucositis was the most common (44.3%) followed by grade 1 (35.7%) and grade 3 (20.0%). Independent risk factors of chemotherapy-induced oral mucositis were female gender (Adjusted Odds Ratio (AOR) = 2.19, 95% confidence interval [CI]: 1.27-3.78; p-value = 0.005), poor oral hygiene (AOR = 3.70, 95% CI: 1.51-9.10; p-value = 0.04), and receiving chemotherapy containing an alkylating agent (AOR = 3.17, 95% CI: 1.63-6.19; p-value < 0.001). CONCLUSION The study found that two out of five chemotherapy patients developed oral mucositis, with nearly half being grade 2. The risk factors identified in our study were comparable to those reported in previous studies. Therefore, identification and assessment of cancer patients at high risk for chemotherapy-induced oral mucositis should be routinely done for proper and timely management.

Abstract
OBJECTIVE This study aimed to verify oral candidiasis, identify the causative species, and investigate the antifungal susceptibility of yeasts isolated from liver transplant patients. METHODS A descriptive analysis of 97 patients who underwent liver transplantation was conducted at a hospital. Two clinical examinations (Collections A and B) of the oral cavity were performed. Oral material was collected from all patients, inoculated in Sabouraud Dextrose Agar, and incubated at 35℃ for 48 hours. Samples were identified by molecular sequencing of the internal trascribed space region of rDNA. RESULTS An antifungal susceptibility test with fluconazole, amphotericin B, and micafungin was performed using the Clinical and Laboratory Standards Institute yeast broth microdilution method. Among the patients, 15 presented with oral candidiasis: eight in Collection A and seven in Collection B. The primary type of candidiasis was atrophic, followed by pseudomembranous candidiasis. The most prevalent species was Candida albicans (nine), followed by Candida glabrata (three), Candida tropicalis (two), and Candida dubliniensis (one). Regarding susceptibility to fluconazole, of the 15 samples, 11 were susceptible, three were susceptible in a dose-dependent manner, and one was resistant. CONCLUSION The most commonly identified type of candidiasis was atrophic, with C. albicans and C. glabrata being the most prevalent causative species. One fluconazole-resistant isolate each of C. tropicalis and C. albicans were identified.

Abstract
Introduction: Studies on head and neck cancer (HNC) patients undergoing radiotherapy have revealed increased numbers of Candida spp., leading to oral candidiasis and oral mucositis. The effects of laser therapy on Candida spp. have been studied with varied results. This study aimed to investigate the effect of low-level laser therapy (LLLT) on C. albicans colonies isolated from HNC patients undergoing radiotherapy. Methods: This study included a treated group, wherein 11 C. albicans isolates were obtained from the saliva of HNC patients undergoing radiotherapy at a dose exceeding 30 Gy. The control groups consisted of an untreated negative control and a positive control treated with nystatin. The treatment groups were subjected to LLLT in continuous mode for 50 seconds at a wavelength of 976 nm, 0.1 W at a dose of 5 J/cm2 for Laser 1 (L1) group and 0.2 W at a dose of 10 J/cm2 for Laser 2 (L2) group. The tests were conducted using C. albicans inoculum equivalent to a 0.5-McFarland suspension on 96-well plates. All test group inoculums were then cultured on Sabouraud dextrose agar (SDA), and the colony count was assessed at 104 CFU/mL. Results: LLLT at 5 and 10 J/ cm2 reduced C. albicans colonies by 7.01% and 10.94%, respectively, but the reductions were not statistically significant (P>0.05). Nystatin eliminated all the colonies. Conclusion: LLLT shows potential for reducing C. albicans colonies in HNC patients undergoing radiotherapy. However, further studies with varied parameters and methods are necessary.

Abstract
Purpose To investigate the survival outcomes and toxicities associated with the addition of nimotuzumab to concurrent chemoradiotherapy (CCRT) in locally advanced nasopharyngeal carcinoma (LANPC) patients who received induction chemotherapy (IC). Methods Patients with stage III-IVA nasopharyngeal carcinoma who received IC and CCRT between January 2017 and October 2021 were retrospectively included. We aimed to compare the locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) between patients treated with CCRT+nimotuzumab and CCRT alone. Results We included 411 patients in the analysis. Of these patients, 267 (65.0%) and 144 (35.0%) had CCRT+nimotuzumab and CCRT alone, respectively. Similar LRFS was found between those with and without nimotuzumab (92.9% vs. 92.6%, p = 0.855). The 3-year DMFS was 88.2% and 76.2% in those with and without nimotuzumab (p = 0.002). The 3-year DFS was 83.4% and 70.6% in those with and without nimotuzumab treatment (p = 0.003). The 3-year OS was 92.1% and 81.1% in those with and without nimotuzumab (p = 0.003). The multivariate Cox regression analysis indicated that the addition of nimotuzumab was independently associated with better DMFS (hazard ratio [HR] 0.606, p = 0.049), DFS (HR 0.613, p = 0.028), and OS (HR 0.497, p = 0.019). No significant differences in major toxicities were found between the two treatment arms, including hematologic toxicities, hepatoxicity, nephrotoxicity, gastrointestinal reactions, and mucositis (all p > 0.05). Conclusion The addition of nimotuzumab to CCRT after IC in LANPC has shown promising results in improving treatment outcomes and acceptable toxicities.

Abstract
BACKGROUND Oral mucositis (OM) is a common and severe side effect of radiotherapy in head and neck cancer (HNC). The study aimed to investigate the longitudinal changes in OM and its influencing factors in patients with HNC during radiotherapy. METHODS This was a retrospective longitudinal observational study. From July 2022 to March 2023, patients with HNC undergoing radiation therapy were enrolled. OM, oral hygiene, oral infections, oral pain, feeding route, and laboratory indicators were measured at 7 times. The influencing factors of OM were analyzed using generalized estimation equations (GEEs). RESULTS A total of 160 patients were included in this study. The prevalence of severe OM at T0, T1, T2, T3, T4, T5, and T6 was 0, 0, 2.5%, 9.4%, 26.9%, 24.4%, and 26.9%, respectively. The prevalence of grade 1-2 OM at T0, T1, T2, T3, T4, T5, and T6 was 0, 16.3%, 53.1%, 65.1%, 61.9%, 70.7%, and 71.3%, respectively. Duration of diagnosis, clinical stage, N stage, M stage, surgery, diabetes, radiotherapy dose, oral hygiene, oral infection, oral pain, feeding route, and lymphocyte impacted OM significantly in the GEEs multivariate model. CONCLUSIONS OM occurs in almost all patients with HNC who undergo radiotherapy. Changes in the severity of OM are a dynamic process, with the severity increasing with the cumulative radiotherapy dose. Specialist oral evaluation and oral care are needed to alleviate the severity of OM in HNC patients.

Proposal of a prophylactic photobiomodulation protocol for chemotherapy-induced oral and oropharyngeal mucositis: a randomized clinical trial. Lasers Med Sci 2023; 38:245. [PMID: 37889325 DOI: 10.1007/s10103-023-03916-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 10/19/2023] [Indexed: 10/28/2023]
Abstract
Photobiomodulation therapy (PBMT) is widely used in oncology settings, but lack of assessment standardization is the main barrier to optimization of clinical protocols. This study analyzed three PBMT protocols for preventing oral and oropharyngeal mucositis (OM) in patients undergoing chemotherapy (CT) and/or hematopoietic stem cell transplantation (HSCT). This is a preliminary randomized blind clinical trial. Group 1 received intraoral prophylactic PBMT, Group 2 received intraoral and oropharyngeal PBMT, and Group 3 received intraoral, oropharyngeal, and extraoral PBMT. The applications were from the first day of CT to day + 10. Clinicodemographic data, CT regimens, types of HSCT, hematological exams, occurrence/severity of OM, odynophagia, and OM-related opportunistic infections were assessed. Sixty participants (age range: 18-74 years) were included; 70% of them underwent CT and 30% HSCT. About 43.3% of patients had OM, while odynophagia was reported by 23.3%. Both Groups 1 and 2 revealed better results. Multivariate analysis showed that HSCT directly influenced the occurrence of OM. Individuals who had undergone allogeneic HSCT were 1.93 times more likely to develop OM (p < 0.001). Group 3 exhibited a higher frequency of OM, albeit of lower grades. This group consisted of half the population who had undergone HSCT, had the highest percentage of melphalan use, and had the lowest mean leukocyte count. The three proposed protocols were effective in preventing and reducing OM, with good tolerance and no reported adverse effects. PBMT is a safe and effective approach to OM prophylaxis in adults undergoing CT/HSCT.

Abstract
Post-oropharyngeal cancer treatment complications include a multitude of oral side effects that impact overall survival and quality of life. These include acute and chronic conditions affecting the oral cavity and head and neck, such as mucositis, infection, xerostomia, dysgeusia, radiation caries, osteonecrosis, and trismus. This review will summarize the most common oral complications from oropharyngeal cancer therapy. The authors would like to point out that the literature cited frequently combines oropharyngeal and head and neck cancer results. If recommendations are made strictly related to oropharyngeal cancers, this will be highlighted.

Abstract
PURPOSE No standard approach other than oral care is available for preventing chemotherapy-induced stomatitis in patients with breast cancer. In this randomized, controlled phase 2 trial, we aimed to assess the efficacy and safety of a dexamethasone-based mouthwash in preventing chemotherapy-induced stomatitis in patients with early breast cancer. BASIC PROCEDURES Patients with breast cancer scheduled for epirubicin and cyclophosphamide (EC) or docetaxel and cyclophosphamide (TC) therapy were selected and allocated in a 1:1 ratio to the intervention and control groups. The intervention group received chemotherapy, oral care, and a dexamethasone-based mouthwash, whereas the control group received chemotherapy and oral care. The primary endpoint was the incidence of stomatitis. This was a phase 2 study, and the significance level for the analysis of the primary endpoint was set a priori at 0.2. MAIN FINDINGS Data pertaining to 58 patients in the control group and 59 patients in the intervention group were analyzed. Stomatitis incidence was 55% and 38% in the control and intervention groups, respectively (risk ratio, 0.68; 80% confidence interval, 0.52-0.88; P = .052). Stomatitis severity was lower in the intervention group than in the control group (P = .03). The proportion of patients who adhered to the mouthwash regimen was 87% (interquartile range, 67.8%-95.3%). No severe oral infections were observed. PRINCIPAL CONCLUSIONS The dexamethasone-based mouthwash safely reduced stomatitis incidence and severity in patients receiving chemotherapy for early breast cancer. Phase 3 clinical trials are warranted for validating our results.

Abstract
Radiation-induced mucositis is the most common, debilitating and painful acute toxicity associated with active treatment in head and neck cancer area, severely affecting more than 65% of patients. Oral microbiota significantly changes during cancer therapy and appears to be involved on its pathophysiology. This review aims to present a comprehensive update of new etiopathogenic factors and treatments that may decrease the incidence of mucositis, mainly modifications of dietary interventions to modify microbiome. Despite advances in recent years, its management is mainly symptomatic opioid-based with variable results on different substances analyzed for its prevention. Immunonutrition seems to play a significant role, particularly the supplementation of compounds such as fatty acids, polyphenols or selected probiotics have shown to promote commensal bacteria diversity and reduced incidence of ulcerative mucositis. Modification of the microbiome is a promising preventive treatment for mucositis although its evidence is still scarce. Large studies are needed to demonstrate the efficacy of interventions on microbiome and its clinical impact on radiation-induced mucositis.

Abstract
Aim: To assess oral microbial status in patients with acute lymphoblastic leukemia (ALL) undergoing high-dose chemotherapy and to unravel possible associations between nosocomial pathogens and the establishment of chemotherapy-induced oral mucositis (CIOM). Methods: Oral mucosa, saliva, and peripheral blood samples were collected from 46 ALL subjects one day prior to chemotherapy (D0) and 2 weeks after treatment initiation (D14). Clinical intraoral inspection was performed by a single practitioner, with mucositis classification performed according to the WHO oral toxicity scale. Blood components were quantified by automatic flow cytometry, while oral Staphylococcus aureus and Pseudomonas aeruginosa were detected by Polymerase Chain Reaction with species-specific primers. Associations among bacteria and clinical findings were determined by Fisher’s Exact test, longitudinal bacterial changes by paired Macnemar, and correlations among blood parameters and mucositis status or bacteria via Mann-Whitney. Results: S. aureus displayed higher detection rates at D14 (p < 0.05) and was positively associated with mucositis, adoption of a non-solid diet (all p < 0.001), nausea and fever (all p < 0.05). Conversely, P. aeruginosa did not correlate to CIOM clinical parameters. At the systemic standpoint, lower hemoglobin levels associated with CIOM and fever events (all p < 0.01). Conclusion: The study evidences S. aureus as a potential pathogen in ALL-CIOM, reaffirming microbial control as an important preventive measure during high-dose immunosuppressive therapy. The weight of non-white-blood-cell parameters should be validated as novel CIOM biomarkers in prospective research.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common oral malignancies. Radiotherapy is the primary noninvasive treatment of OSCC for avoiding surgery-induced facial deformities and impaired oral function. However, the specificity of in situ OSCC limits radiotherapeutic effects because of the hypoxia-induced low radiosensitivity of tumors and the low radiation tolerance of surrounding normal tissues. Here, we design a highly efficient and low-toxic radiosensitization strategy. On the one hand, biocompatible poly(vinyl pyrrolidone)-modified tantalum nanoparticles (Ta@PVP NPs) not only have strong X-ray deposition capability to upregulate oxidative stress but also have photothermal conversion efficiency to improve hypoxia for tumor radiosensitivity. On the other hand, to optimize the spatial distribution of Ta@PVP NPs within tumors, mussel-inspired catechol with bioadhesive properties is grafted on tumor microenvironment-responsive sodium alginate (DAA) to form in situ hydrogels for precision radiotherapy. On this basis, we find that Ta@PVP-DAA hydrogels effectively inhibit OSCC development in mice under photothermal-assisted radiotherapy without facial deformities and damage to surrounding normal tissues. Overall, our work not only promotes the exploration of Ta@PVP NPs as new radiosensitizers for OSCC but also develops a nanocomposite hydrogel system strategy as a promising paradigm for the precision treatment of orthotopic tumors.

Abstract
Abstract
Background
Oral mucositis is the dose-limiting toxicity of chemoradiation in oropharyngeal cancer patients, which can be minimized by giving constraints to oral mucosa. However, the constraints defined in literature are extrapolated from chemoradiation in head and neck cancers as a whole. This study aims to determine oral mucosa dose-volume parameters that can predict grade ≥ 3 acute oral mucositis in oropharyngeal cancer patients treated with volumetric modulated arc radiotherapy.
Methods
This prospective study was done in 52 patients of locally advanced oropharyngeal cancer treated with Volumetric modulated arc radiotherapy. Dose-volume histogram data were extracted and then acute oral mucosa toxicity was analysed. Receiver operating characteristic analysis and logistic regression were carried out to determine predictive factors for grade ≥ 3 mucositis.
Results
Grade ≥ 3 acute oral mucositis occurred in 57.6% (30/52) patients in the study. V30Gy > 53.35% (P = 0.005) was an independent dosimetric factor related to grade ≥ 3 acute toxicity. In the receiver operating characteristic curve, the area under V30Gy was 0.770 (P = 0.001); the cut-off value of V30 was 46.23% (sensitivity, 0.80; specificity, 0.91).
Conclusions
Dose-volume histogram analysis predicts V30 > 53.35% as independent factors for grade ≥ 3 acute oral mucositis in patients with oropharyngeal cancers treated with Volumetric modulated arc radiotherapy. Studies in future with more patient number can further validate the above results.

Abstract
Growing evidence suggests that oral infections can modify the course of systemic diseases. To date, epidemiological data on microbial oral infections are scarce. Here, we performed a comprehensive analysis of the trend and microbial diversity in oral infection specimens referred for clinical microbiology analysis from 2010 to 2020. The microbes were isolated by culture and were identified via matrix-assisted laser desorption ionization-time of flight mass spectrometry technology (MALDI-TOF MS) throughout the study period. A total of 1,014 referred samples from dental clinics in Stockholm County with dentoalveolar abscesses and jaw osteomyelitis being the main reason were identified. Overall, the microbial composition was dominated by Firmicutes (51%), followed by Bacteroidetes (19%), Proteobacteria (12%), and Actinobacteria (5%). At the genus level, Streptococcus spp. (36%), Prevotella spp. (18%), and Staphylococcus spp. (11%) were among the most frequently reported. Interestingly, a strong increase in trend was noted for Streptococcus anginosus, Streptococcus mitis, Streptococcus sanguinis, Eikenella corrodens, Actinomyces spp., Aggregatibacter aphrophilus, Staphylococcus epidermidis, and Granulicatella adiacens during the study time (R = 0.66 to 0.89, P < 0.05), and a minor increase was noted for Enterococcus faecalis and Klebsiella spp., whereas steady levels were noted for most of the others. The present study shows the diversity of bacteria that have been involved in dental infections during the last decade in the capital of Sweden, as well as the emerging oral microbiota trend, with clear clinical implications on the oral-systemic link. IMPORTANCE Oral diseases and associated microbes are a risk factor for systemic diseases and can change the courses of these diseases. To date, epidemiological data on microbial oral infections are scarce, and longitudinal reports are lacking. We present for the first time the microbial composition of severe oral bacterial infections determined via the MALDI-TOF mass spectrometry technique in a comprehensive study between 2010 and 2020 (11 years) in Stockholm County. The trend and microbial diversity of oral infections were analyzed on referred clinical microbiological samples and were processed by standardized protocols. Trend increase was noted for Streptococcus anginosus, Streptococcus mitis, Streptococcus sanguinis, Eikenella corrodens, Actinomyces spp., Aggregatibacter aphrophilus, Staphylococcus epidermidis, Granulicatella adiacens, Enterococcus faecalis, and Klebsiella spp. Our results provide new insights into the diversity and trend of oral microbiota that were involved in serious oral infections over the past decade in the capital of Sweden and may influence the oral-systemic link.

Biomedicines 2022; 10:biomedicines10102661. [PMID: 36289923 PMCID: PMC9599791 DOI: 10.3390/biomedicines10102661] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 10/15/2022] [Accepted: 10/17/2022] [Indexed: 11/16/2022] Open
Abstract
Radiation-induced mucositis in head and neck cancer patients generates difficulties in eating and swallowing, and may influence treatment tolerance, compliance, and quality of life. However, predictive factors have not been studied in detail. Thus, the aim of this study was to describe the association between pre-radiotherapy clinical factors and the incidence of severe radiation-induced mucositis in nasopharyngeal or oropharyngeal cancer patients. This retrospective study included all patients with definitive radiotherapy or chemoradiotherapy for nasopharyngeal or oropharyngeal cancer between July 2011 and June 2021 in a single center. The eligibility criteria included patients who received oral management during radiotherapy. Exclusion criteria was patients who received postoperative radiotherapy. The data were acquired from the medical records of patients. One hundred patients were included in this retrospective study. Grade 3 radiation-induced mucositis occurred in 47 patients (47%). Lymphocyte count was significantly associated with grade 3 mucositis (OR = 0.40; 95% CI = 0.19–0.86; p = 0.018). It is suggested that pre-radiation lower lymphocyte counts are a predictive risk factor for severe mucositis in patients who undergo definitive radiotherapy or chemoradiotherapy for nasopharyngeal or oropharyngeal cancer

Comparison of methods for the handling of metallic dental restorations before head and neck radiotherapy. Support Care Cancer 2022; 30:10285-10290. [PMID: 36239800 DOI: 10.1007/s00520-022-07406-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 10/10/2022] [Indexed: 10/17/2022]
Abstract
PURPOSE During head and neck radiotherapy, backscatter from metallic dental restorations (MDRs) causes oral mucositis. Currently, two MDR handling methods are used: the replacement of MDRs with provisional restorations (MDR removal) and fabrication of dental spacers before radiotherapy. We compared the effects of these two methods on the incidence of oral mucositis during head and neck radiotherapy. METHODS We enrolled 76 patients with MDRs who underwent radiotherapy for head and neck cancer between April 2016 and March 2020. We set grade 2 oral mucositis as an outcome. After adjustment of all covariates using the propensity score (PS), we analyzed the data using a Cox proportional hazards model. In addition, subgroup analysis was performed by stratifying the data into quintiles based on the PS. RESULTS For the incidence of grade 2 oral mucositis due to head and neck radiotherapy, the hazard ratio for the MDR removal group relative to the dental spacer group was 0.344 (95% confidence interval, 0.121-0.980; P = 0.046). Subgroup analysis showed that the hazard ratio for the MDR removal group was 0.339 (95% confidence interval, 0.122-0.943; P = 0.038). CONCLUSION The results suggest that MDR replacement is superior to dental spacer fabrication in reducing the incidence of oral mucositis during head and neck radiotherapy, although MDR removal carries several associated risks.

Oral Candida spp. Colonisation Is a Risk Factor for Severe Oral Mucositis in Patients Undergoing Radiotherapy for Head & Neck Cancer: Results from a Multidisciplinary Mono-Institutional Prospective Observational Study. Cancers (Basel) 2022; 14:cancers14194746. [PMID: 36230669 PMCID: PMC9564084 DOI: 10.3390/cancers14194746] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 09/22/2022] [Accepted: 09/27/2022] [Indexed: 11/25/2022] Open
Abstract
Simple Summary This study aims to find a correlation between Candida spp. oral colonisation prior to radiotherapy and (i) the development of severe oral mucositis (OM) (grade 3/4) and (ii) early development of severe OM (EOM). Candida spp. in the oral cavity appears to be a predictive factor of EOM. Preventive treatment could aid in reducing incidence of EOM. Further clinical trials are required to confirm our findings. Abstract Background: This study aims to find a correlation between Candida spp. oral colonisation prior to radiotherapy (RT) and (i) the development of severe oral mucositis (OM) (grade 3/4) and (ii) early development of severe OM (EOM). Methods: The protocol was registered on ClinicalTrials.gov (ID: NCT04009161) and approved by the ethical committee of the ‘Fondazione Policlinico Universitario Gemelli IRCCS’ (22858/18). An oral swab was obtained before RT to assess the presence of Candida spp. Severe OM occurring before a dose of 40 Gy was defined as EOM. Results: No patient developed G4 OM, and only 36/152 patients (23.7%) developed G3 OM. Tumour site and lymphocytopenia were risk factors for severe OM (OR for tumour site: 1.29, 95% CI: 1–1.67, p = 0.05; OR for lymphocytopenia: 8.2, 95% CI: 1.2–55.8, p = 0.03). We found a correlation between Candida spp. and EOM (OR: 5.13; 95% CI: 1.23–21.4 p = 0.04). Patients with oral colonisation of Candida spp. developed severe OM at a mean dose of 38.3 Gy (range: 28–58; SD: 7.6), while negative patients did so at a mean dose of 45.6 Gy (range: 30–66; SD: 11.1). Conclusions: Candida spp. in the oral cavity appears to be a predictive factor of EOM.

Abstract
Oral complications of cancer therapy are common, markedly symptomatic, negatively impact patients' quality of life, and add significantly to the cost of care. Patients' risk of treatment-related toxicities is not uniform; most patients suffer at least one side effect, while others tolerate treatment without any. Understanding those factors which impact risk provides opportunities to customize cancer treatment plans to optimize tumor kill and minimize regimen-related toxicities. Oral mucositis (OM) is an iconic example of a clinically significant and common complication of head and neck radiotherapy. Individuals' OM risk is governed by the cumulative impact of factors related to treatment, the tumor, and the patient. In addition to OM risk prediction, a second opportunity to apply precision medicine will evolve as viable treatment options become available. Patients vary widely in how well or poorly they respond to specific treatments. What works well in one individual, might fail in another. Prospective determination of the likelihood of a patient's response or non-response is based on a range of biological interactions. Coupled with risk determination, the application of precision medicine will allow caregivers, patients, and payers to integrate risk/benefit to optimize the probability that the best treatment is be given to the most appropriate patients.

Abstract
Elevated numbers of candida in the oral cavity often lead to oral candidiasis development in patients undergoing radiotherapy for oral or oropharyngeal cancer. This study aimed to verify the effect of miconazole mucoadhesive tablets on suppression of oral candida infection during radiotherapy. For this preliminary interventional study, miconazole mucoadhesive tablets were attached to the oral mucosa for 14 days from when grade 2 oral mucositis appeared in patients with oral or oropharyngeal cancer receiving radiotherapy, and the incidence of oral candidiasis was investigated. Various clinical factors were examined; univariate and multivariate Cox regression analyses were performed to investigate and compare the efficacy of this drug in preventing oral candidiasis with results of our previous study as historical control. Miconazole mucoadhesive tablets were administered to 18 patients, and oral candidiasis was observed in one patient (5.6%) after treatment completion. Among 144 historical control patients, 43 (29.9%) developed oral candidiasis. Multivariate Cox regression showed that miconazole mucoadhesive tablets significantly reduced oral candidiasis development during radiotherapy (p = 0.049, Hazard ratio 0.136, 95% confidence interval 0.019–0.994). This preliminary study suggests the efficacy of miconazole mucoadhesive tablets in preventing oral candidiasis in oral or oropharyngeal cancer patients treated with radiotherapy.

Abstract
Treatment of locally advanced head and neck carcinoma not amenable for surgical resection or resected with high-risk features is usually based on (chemo-)radiation treatment. Oral mucositis represents one of the main side effects of (chemo-)radiation, with an important impact on quality of life and causing approximately 20% of early interruption of treatment, leading to a suboptimal dose administered. Treatment and prevention of oral mucositis have a central role in the therapeutic pathways of head and neck cancer patients but remains quite challenging. Although extensive research is conducted to identify interventions for the management of mucositis, very few interventions had sufficient evidence to generate an international expert consensus. This may be partially explained by confounding factors that could influence the development and assessment of oral mucositis. Little is known about the confounding factors of oral mucositis, which, if not well balanced in an experimental study, could lead to non-solid results. The current paper aims to review the main oral mucositis confounding factors related to head and neck cancer patients.

Abstract
The study investigated the relationship between genetic polymorphisms and the development of oral mucositis in pediatric patients undergoing chemotherapy involving methotrexate. A longitudinal study was conducted with 64 patients, and oral mucositis was evaluated by the modified Oral Assessment Guide, which aims to diagnose and classify oral mucositis. Epithelial cells were obtained by mouthwash and DNA was extracted. The polymorphisms MTHFR (rs1801133), DNMT3B (rs2424913), ABCC2 (rs717620), ABCG2 (rs2231137) and ABCG2 (rs2231142) were analyzed by PCR-RFLP method. Demographic, hematological and biochemical data were collected from medical records. Statistical analysis was performed using the SPSS software adopting a p-value of 0.05. Male sex predominated (56.2%), and the mean age was 10.8 years (± 4.9). Oral mucositis affected 65.6% of the patients, of which 61.9% developed the severe form of the disease. For the ABCG2 gene (rs2231142), the rare A allele and CA genotype were more frequent in individuals with mucositis (p= 0.02; RR = 0.60; CI = 0.387 - 0.813). The severity of the disease was mainly observed in younger patients (median = 9 years; p=0.02). Patients with severe oral mucositis presented lower leukocytes count (median = 2.150 mm3) compared to patients with the mild/moderate form (median = 4.200 mm3; p=0.03). Female patients and each 10,000-platelet increase were protective factors against the onset of oral mucositis (p=0.02). It is concluded that rs2231142 polymorphism increases the likelihood of oral mucositis and younger patients and patients with low leukocytes counts are more likely to develop severe form.

Abstract
BACKGROUND/PURPOSE Radiotherapy for head and neck cancer often causes severe oral mucositis. The purpose of this retrospective study was to further examine the risk factors for developing severe oral mucositis in patients with oral cancer undergoing radiotherapy as a compliment to a previous study performed by our group. MATERIALS AND METHODS A total of 181 patients with oral cancer undergoing radiotherapy were enrolled in the study. The association between a number of potential risk factors and grade 3 oral mucositis were analyzed using the cox proportional hazard model and a logistic regression analysis. RESULTS Grade 3 oral mucositis occurred in 56 patients. The cox proportional hazard model analysis revealed that those with lower hemoglobin levels, concurrent cisplatin and cetuximab administration, and a larger number of teeth showed a significantly higher incidence of severe oral mucositis. Logistic regression analysis revealed that patients who had lower hemoglobin levels, received concurrent cisplatin or cetuximab treatment, and were not administered pilocarpine showed a significantly higher incidence of severe oral mucositis. The presence of teeth may stimulate the oral mucosa and become a risk factor for mucositis, and the administration of pilocarpine might reduce the risk. CONCLUSION This study describes the risk factors of severe radiation-induced oral mucositis in oral cancer patients and shows the possibility of risk reduction by pilocarpine. This information could help patients avoid painful mucositis.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation that informs clinical decisions regarding recurrence and overall survival in most epithelial cancers. Radiotherapy for head and neck cancer leads to mucositis in almost all patients and severe radiation-mucositis affects their quality of life (QOL). However, little is known about the NLR for severe mucositis. Therefore, this study aimed to show the association between the NLR and severe radiation-induced mucositis in hypopharyngeal or laryngeal cancer patients. METHODS In this retrospective study, we determined the incidence of grade 3 mucositis in 99 patients who were receiving definitive radiotherapy or chemoradiotherapy (CRT) for hypopharyngeal or laryngeal cancer. We performed univariate and multivariate logistic regression analyses to investigate the characteristics of grade 3 mucositis. Kaplan-Meier curves and log-rank tests were used to evaluate the occurrence of grade 3 mucositis between two groups with high (NLR > 5) or low (NLR < 5) systemic inflammation. RESULTS The incidence of grade 3 mucositis was 39%. Univariate logistic regression analysis showed that the NLR (Odd ratio [OR] = 1.09; 95% confidence interval [CI] = 1.02-1.16; p = 0.016) and smoking (OR = 1.02; 95% CI = 1.00-1.03; p = 0.048) were significantly associated with grade 3 mucositis. Multivariate logistic regression analysis showed that the NLR was independently associated with grade 3 mucositis (OR = 1.09; 95% CI = 1.01-1.17; p = 0.021). Kaplan-Meier curves also showed that patients with higher NLR (NLR > 5) prior to radiotherapy developed grade 3 mucositis more frequently than those with lower NLR during radiotherapy (p = 0.045). CONCLUSION This study suggests that a higher NLR is a risk factor and predictor of severe radiation-induced mucositis in hypopharyngeal or laryngeal cancer patients.

[PMID: 34521398 PMCID: PMC8442420 DOI: 10.1186/s12906-021-03400-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 08/29/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND One of the most prevalent complications of chemotherapy and radiotherapy is oral mucositis (OM) and manifests as erythema and ulceration. Curcumin is one of the components of turmeric and possesses anti-inflammatory and anti-oxidative features. Some of studies have proved the effectiveness of Curcumin in OM. This study aimed to investigate the effects of nanomicelle Curcumin on OM related chemotherapy and head and neck radiotherapy. METHODS In this clinical trial study, 50 patients underwent chemotherapy with or without head and neck radiotherapy were divided into study and control group. The study group was received Curcumin nanomicelle capsules 80 mg twice a day and the control group took placebo two times a day for 7 weeks and the severity and pain of OM was measured. RESULTS Oral mucositis severity in control group in the first (P = 0.010), fourth (P = 0.022) and seventh (P < 0.001) weeks were significantly more than the study group. Pain grade in study group was lower than control group only in the seventh week. (P = 0.001) Additionally, NRS incremental gradient in control group was more than study group. OM severity in patients who underwent only chemotherapy in the control group were significantly more than the study group in all weeks. In patients who were under chemotherapy and head and neck radiotherapy, OM in control group was significantly more intense than the study group only in the fourth and seventh weeks. CONCLUSIONS Nabomicelle Curcumin capsules is effective on prevention and treatment of head and neck radiotherapy and especially chemotherapy induced OM.

Abstract
OBJECTIVE Ulcerative mucositis (UM) is a devastating complication of most cancer therapies with less recognized risk factors. Whilst risk predictions are most vital in adverse events, we utilized Machine learning (ML) approaches for predicting chemotherapy-induced UM. METHODS We utilized 2017 National Inpatient Sample database to identify discharges with antineoplastic chemotherapy-induced UM among those received chemotherapy as part of their cancer treatment. We used forward selection and backward elimination for feature selection; lasso and Gradient Boosting Method were used for building our linear and non-linear models. RESULTS In 2017, there were 253 (unweighted numbers) chemotherapy-induced UM patient discharges from 21,626 (unweighted numbers) adult patients who received antineoplastic chemotherapy as part of their cancer treatment. Our linear model, lasso showed performance (C-statistics) AUC: 0.75 (test dataset), 0.75 (training dataset); the Gradient Boosting Method (GBM) model showed AUC: 0.76 in the training and 0.79 in the test datasets. The feature selection derived from stepwise forward selection and backward elimination methods showed variables of importance--antineoplastic chemotherapy-induced pancytopenia, agranulocytosis due to cancer chemotherapy, fluid and electrolyte imbalance, age, anemia due to chemotherapy, median household income, and depression. Higher importance variable derived from GBM in the order of importance were antineoplastic chemotherapy-induced pancytopenia > co-morbidity score > agranulocytosis due to cancer chemotherapy > age > and fluid and electrolyte imbalance. Further, when the analysis was stratified to females only, the ML models performed better than the unstratified model. CONCLUSION Our study showed ML methods performed well in predicting the chemotherapy-induced UM. Predictors identified through ML approach matched to the clinically meaningful and previously discussed predictors of the chemotherapy-induced UM.

Effect of Prophylactic Radiotherapy on Patients with Stage II-III Esophageal Cancer after Esophageal Cancer Radical Operation and Influencing Factors in Its Recurrence. JOURNAL OF ONCOLOGY 2021; 2021:7462012. [PMID: 34462636 PMCID: PMC8403052 DOI: 10.1155/2021/7462012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 07/29/2021] [Accepted: 08/10/2021] [Indexed: 11/21/2022]
Abstract
Objective To explore the effect of prophylactic radiotherapy on patients with stage II-III esophageal cancer (EC) after esophageal cancer radical operation (ECRO) and influencing factors on EC recurrence. Methods Totally, 65 patients with EC in our hospital were enrolled. Among them, 30 patients were treated by routine ECRO as a control group (Con group) and 35 patients by prophylactic radiotherapy as a research group (Res group). Then, the following measures were taken: record the efficacy on both groups, quantify their C-reactive protein (CRP) and white blood cell count (WBC) before and after therapy, evaluate their mental state through the revised piper fatigue scale (PFS-R) before and after therapy, determine their changes in Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after therapy, compare them in terms of lymph-node metastatic rate (LNMR), hematogenous metastasis rate (HMR), anastomotic recurrence rate (ARR), and 3-year survival rate, compare them in terms of life quality after therapy via the Quality of Life-Core Questionnaire (QLQ-C30), and analyze influencing factors on their recurrence. Results The Res group showed a notably higher total effective rate (TER) than the Con group (P=0.037). After therapy, CRP and WBC in both groups increased, but their levels were not considerably different in both (P > 0.05). Additionally, after therapy, in contrast to the Con group, the Res group got notably lower PFS-R, SDS, and SAS scores, showed notably lower LNMR and ARR and notably higher 3-year survival rate, and experienced notably higher life quality (all P < 0.05), and the HMR results were not considerably different in both groups (P > 0.05). Moreover, carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), esophageal inflammation history, family medical history, postoperative complications, and lymphatic and vascular infiltration were risk factors for the disease recurrence, and treatment method was the protective factor for it. Conclusion For patients with stage II-III EC after ECRO, prophylactic radiotherapy is highly effective and safe and can lower the recurrence rate, so it is worth popularizing in clinical practice.

Effects of a miconazole oral patch on preventing development of oral candidiasis in patients with head and neck cancer undergoing radiotherapy: results of a preliminary study quantifying the prevalence of Candida albicans in saliva. Support Care Cancer 2021; 30:907-914. [PMID: 34410460 DOI: 10.1007/s00520-021-06480-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Accepted: 07/28/2021] [Indexed: 12/24/2022]
Abstract
PURPOSE Serious oral mucositis develops during radiation therapy (RT) for head and neck cancer, but there is no effective preventive method. We have used a steroid ointment to prevent oral mucositis during RT, but the use of steroid ointment is discontinued when oral candidiasis develops. Therefore, prevention of oral candidiasis is important. The purpose of this study was to examine whether administration of a miconazole oral patch reduced the amount of Candida albicans in saliva and prevented the development of oral candidiasis during RT. METHODS Participants were patients with head and neck cancer receiving RT ≥ 60 Gy. Patients in the intervention group received miconazole oral patches for 14 days after the appearance of grade 2 oral mucositis. The control group received oral care only. Total bacteria and C. albicans counts in the saliva were analyzed by real-time polymerase chain reaction. The incidence of oral candidiasis was compared between the groups. RESULTS Total bacterial counts did not change throughout RT in either the intervention or the control group. However, C. albicans count significantly increased at 30 Gy and 60 Gy in the control group but was suppressed in the intervention group. The saliva pH did not show a significant change throughout RT in either group. The incidence of oral candidiasis in the intervention group tended to be lower than that in the control group. CONCLUSION This study suggested that prophylactic use of a miconazole oral patch was effective in suppressing the growth of C. albicans count in saliva during RT for head and neck cancer.

Abstract
Objectives To evaluate the association and risk factors of healthcare-associated infection (HAI) and burden of illness among chemotherapy-induced ulcerative mucositis (UM) patients. Methods For this research, US National Inpatient Sample database 2017 was utilized to study UM patients. The association of healthcare-associated infection-related burden of illness among UM patients was assessed on the outcome––length of hospital stays (LOS), total charges, in-hospital mortality, and discharge disposition. Result In 2017, there were 11,350 adult (> 18 years of age) UM patients, among them there were 415 (3.5%) HAI. After adjusting for patient and clinical characteristics, UM patients with HAI were most likely to have higher total charges and longer LOS (1.91; 95% CIs: 1.51–2.41; P < 0.001; 1.84; 95% CIs: 1.53–2.21; P < 0.001) than those without HAI. Further, mortality was not significantly different. UM patients with HAI were less likely to have higher burden of illness who were younger, females, those living in non-metropolitan or micropolitan counties, and those with lower co-morbidity score. Additionally, UM patients with HAI were more likely to discharge to skilled nursing facility (SNF), intermediate care facility (ICF), and another type of facility (ATF), (aOR = 2.58 (1.16–5.76), P = 0.02), than they were to discharge to self-care or home care. Conclusion UM patients with HAI were more likely to have higher burden of illness and more likely to discharged to the SNF, ICF, and ATF rather than to home or self-care. Clinical relevance UM patients when associated with HAI have higher burden of illness; a tailored approach to oral care might prevent HAIs and burden of illness among UM.

Abstract
Objective: In this study, by comparing coplanar and noncoplanar intensity-modulated radiation therapy (IMRT) treatment planning in treating tongue cancer, the significance of noncoplanar fields in the protection of the lip and buccal mucosa was determined, and a reasonable solution was selected. Methods: Forty-eight tongue cancer patients treated from June 2019 to February 2021 were selected and randomly divided into a coplanar field group and a noncoplanar field group. The mucosal dose limit changed from 15 Gy to 45 Gy for comparison of the two treatment plans. The evaluation indicators (conformal index (CI); homogeneity index (HI); D5, D50, and D98 of the target volume; and the dose of normal tissues) were calculated under different mucosal dose limits. The clinical observation of the lip and buccal mucosa of 48 cases was monitored and graded carefully according to NCI-CTCAE V4.0. Statistical analyses were performed. Results: The differences in CI, HI, D98, D50 and D5 between the two groups in the target volume tended to decrease when the mucosal dose limit was less than 30 Gy, with a significant difference (P < 0.05). When the limit exceeded 30 Gy, significant differences in other indicators except CI (P < 0.05) were still noted. In normal tissue, differences in doses between the two groups existed when the mucosal limit was less than 20 Gy, with a significant difference (P < 0.05). When the limit exceeded 20 Gy, no significant difference was noted. Patients in the noncoplanar group showed significantly better results than those in the other group in terms of the radiation-related toxicity of the lip and cheek membrane(P < 0.001). Conclusions: Compared with coplanar field radiotherapy, noncoplanar field radiotherapy can effectively reduce the exposure dose to the lip and buccal mucosa. The application of noncoplanar treatment plans exhibits good clinical significance and deserves to be promoted.

Abstract
Study of the human microbiota has been a centuries-long endeavor, but since the inception of the National Institutes of Health (NIH) Human Microbiome Project in 2007, research has greatly expanded, including the space involving radiation injury. As acute radiation syndrome (ARS) is multisystemic, the microbiome niches across all areas of the body may be affected. This review highlights advances in radiation research examining the effect of irradiation on the microbiome and its potential use as a target for medical countermeasures or biodosimetry approaches, or as a medical countermeasure itself. The authors also address animal model considerations for designing studies, and the potential to use the microbiome as a biomarker to assess radiation exposure and predict outcome. Recent research has shown that the microbiome holds enormous potential for mitigation of radiation injury, in the context of both radiotherapy and radiological/nuclear public health emergencies. Gaps still exist, but the field is moving forward with much promise.

Abstract
PURPOSE To investigate the incidence and risk factors for oral mucositis (OM) in patients with childhood cancer undergoing chemotherapy. METHODS Eight hundred and twenty-nine cycles of chemotherapy were evaluated in 112 patients with childhood cancer undergoing chemotherapy. Chemotherapy protocol, hematological, hepatic, and renal function parameters were collected and compared to presence and severity of OM, as graded by the World Health Organization (WHO) scale. Patients received counseling on oral hygiene and those who presented with OM (grade ≥1) received photobiomodulation therapy (PBMT). RESULTS Age ranged from 0 to 17 years (mean/SD, 8.58 ± 5.05) and fifty-one patients (45.54%) were females. The most common baseline diseases were leukemia (51%) followed by sarcomas (23%) and lymphomas (18%). Eight hundred and twenty-nine cycles of chemotherapy were evaluated, and OM was diagnosed in 527 cycles (63.57%). Higher incidence and severity of OM was observed in protocols using high-dose methotrexate (MTX-HD), MTX-HD cyclophosphamide/doxorubicin combination, and MTX-HD combined with cyclophosphamide (p <0.001). Patients with severe OM had lower levels of leukocytes (p = 0.003), hemoglobin (p = 0.005), platelets (p = 0.034), and higher levels of total bilirubin (p = 0.027), alanine aminotransferase (ALT) (p = 0.001), and creatinine (p = 0.007). CONCLUSION The study contributes to the elucidation of the risk factors for OM in pediatric cancer patients. Chemotherapy protocols using MTX-HD, MTX-HD associated with doxorubicin and cyclophosphamide, and MTX-HD and cyclophosphamide a have higher incidence of severe grades of OM. Other toxicities such as hematological, hepatic, and renal also developed in patients with OM.

Abstract
Radiation-induced oral mucositis (RIOM) is one of the most frequent complications in head and neck cancer (HNC) patients undergoing radiotherapy (RT). It is a type of mucosal injury associated with severe pain, dysphagia, and other symptoms, which leads to the interruption of RT and other treatments. Factors affecting RIOM include individual characteristics of HNC patients, concurrent chemoradiation therapy, and RT regimen, among others. The pathogenesis of RIOM is not yet fully understood; however, the release of inflammatory transmitters plays an important role in the occurrence and development of RIOM. The five biological stages, including initiation, primary damage response, signal amplification, ulceration, and healing, are widely used to describe the pathophysiology of RIOM. Moreover, RIOM has a dismal outcome with limited treatment options. This review will discuss the epidemiology, pathogenesis, clinical appearance, symptomatic treatments, and preventive measures related to this disease. We hope to provide a reference for the clinical treatment and prevention of RIOM in HNC patients after RT.

Effects of a bioadhesive barrier-forming oral liquid on pain due to radiation-induced oral mucositis in patients with head and neck cancer: A randomized crossover, preliminary study. J Dent Sci 2021; 16:96-100. [PMID: 33384784 PMCID: PMC7770299 DOI: 10.1016/j.jds.2020.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 07/10/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND/PURPOSE Bioadhesive barrier-forming oral liquid, is a recently developed medical material for the management of pain caused by oral mucositis associated with cancer radiotherapy or chemotherapy. The purpose of this study was to evaluate the effectiveness of this liquid in relieving pain resulting from radiation-induced oral mucositis in patients with head and neck cancer. MATERIALS AND METHODS This randomized, crossover trial investigated the analgesic effects of bioadhesive barrier-forming oral liquid using dexamethasone ointment as a control. Fifteen patients with mild or moderate pain due to radiation-induced oral mucositis were randomly assigned to two groups. Group A applied dexamethasone ointment once on day 1, had a wash-out period on day 2, and used bioadhesive barrier-forming oral liquid once on day 3. Conversely, group B used bioadhesive barrier-forming oral liquid on day 1, had a wash-out period on day 2, and applied dexamethasone ointment once on day 3. The effectiveness in relieving pain was compared between the two groups. RESULTS One patient reported nausea immediately after the application of bioadhesive barrier-forming oral liquid and was therefore excluded from the analysis. Dexamethasone ointment and bioadhesive barrier-forming oral liquid relieved pain in 85.7% and 71.4% patients, respectively (p = 0.682). Nine patients wished to continue dexamethasone ointment after the study, while only five wished to continue bioadhesive barrier-forming oral liquid. CONCLUSION Our findings suggest that the analgesic effect of bioadhesive barrier-forming oral liquid is comparable or inferior to that of dexamethasone ointment in patients with radiation-induced oral mucositis. Further studies are needed to verify these findings.

Arch Oral Biol 2020; 119:104906. [PMID: 32947164 DOI: 10.1016/j.archoralbio.2020.104906] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/27/2020] [Accepted: 08/28/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE This study determined the prevalence of Candida spp. in the saliva of cancer patients. Furthermore, we assessed the antimicrobial activity of mouthwashes against the isolated strains and its susceptibility to amphotericin B and fluconazole. METHODS Thirty-four cancer patients undergoing radiotherapy, chemotherapy alone or combined treatment were investigated for oral Candida spp. colonization and compared in regard to mucositis presence. The maximum inhibitory dilution was used to assess the antimicrobial activity of Periogard®, Cepacol® Cool Ice and 0.12 % Chlorhexidine Digluconate mouthwashes against the isolates. In parallel, susceptibility to amphotericin B and fluconazole was determined by agar-based E-test. Data did not adhere to normal distribution as inferred by the Shapiro-Wilk test and statistical analysis was conducted by non-parametric McNemar test (α0.05). RESULTS Twenty-seven participants (79.4 %) were male, 19 (55.9 %) had mucositis and 9 (26.5 %) were colonized by Candida spp. 12 different strains of Candida spp. were isolated, being Candida albicans the most prevalent strain. Risk of Candida spp. colonization was increased by almost twofold among the participants with mucositis (odds ratio: 1.84; 95 % confidence interval: 0.37-9.07). Mouthwash Cepacol® Cool Ice presented better antimicrobial activity against Candida spp. while 0.12 % Chlorhexidine exhibited the worst activity. All strains were sensitive to amphotericin B, and 2 non-albicans strains were dose-dependent sensitive to fluconazole. CONCLUSION Considering the increased risk of colonization byCandida spp. in patients with mucositis, and the emergence of antifungal drug resistance, the antiseptics use could benefit the maintenance of cancer patient's oral health.

Prediction of mucositis risk secondary to cancer therapy: a systematic review of current evidence and call to action. Support Care Cancer 2020; 28:5059-5073. [PMID: 32592033 DOI: 10.1007/s00520-020-05579-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Accepted: 06/12/2020] [Indexed: 01/25/2023]
Abstract
PURPOSE Despite advances in personalizing the efficacy of cancer therapy, our ability to identify patients at risk of severe treatment side effects and provide individualized supportive care is limited. This is particularly the case for mucositis (oral and gastrointestinal), with no comprehensive risk evaluation strategies to identify high-risk patients. We, the Multinational Association for Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO) Mucositis Study Group, therefore aimed to systematically review current evidence on that factors that influence mucositis risk to provide a foundation upon which future risk prediction studies can be based. METHODS We identified 11,018 papers from PubMed and Web of Science, with 197 records extracted for full review and 113 meeting final eligibility criteria. Data were then synthesized into tables to highlight the level of evidence for each risk predictor. RESULTS The strongest level of evidence supported dosimetric parameters as key predictors of mucositis risk. Genetic variants in drug-metabolizing pathways, immune signaling, and cell injury/repair mechanisms were also identified to impact mucositis risk. Factors relating to the individual were variably linked to mucositis outcomes, although female sex and smoking status showed some association with mucositis risk. CONCLUSION Mucositis risk reflects the complex interplay between the host, tumor microenvironment, and treatment specifications, yet the large majority of studies rely on hypothesis-driven, single-candidate approaches. For significant advances in the provision of personalized supportive care, coordinated research efforts with robust multiplexed approaches are strongly advised.

Abstract
PURPOSE Oral mucositis (OM) remains a significant complication developed by many patients undergoing radiotherapy (RT) to the head and neck region. Emerging data suggest oral microbes may contribute to the onset and severity of this acute side effect. METHODS In this study, saliva and oral swabs from head and neck cancer patients undergoing RT were collected. We employed molecular microbiological techniques to study the bacterial communities present in saliva, and both the bacterial and fungal communities present on the buccal mucosa and lateral tongue. Changes in microbiota composition with increasing radiation dose and the presence of mucositis were examined. RESULTS The data suggest that the salivary microbiota remain stable during RT and are consistently dominated by Streptococcus, Prevotella, Fusobacterium and Granulicatella. Obligate and facultative anaerobic Gram-negative bacilli (GNB) Bacteroidales G2, Capnocytophaga, Eikenella, Mycoplasma and Sneathia, as well as anaerobic GNB in the periopathogenic genera Porphyromonas and Tannerella, were all positively correlated with ≥ grade 2 OM. Significant increases in the relative abundances of Bacteroidales G2, Fusobacterium and Sneathia were identified in buccal mucosa swabs at sites of ≥ grade 2 OM (p < 0.05). Furthermore, the abundance of several GNB (Fusobacterium, Haemophilus, Tannerella, Porphyromonas and Eikenella) on the buccal mucosa may influence patient susceptibility to developing OM. Candida was widely detected in buccal mucosa swabs, regardless of mucositis status. CONCLUSIONS Our findings support previously hypothesized associations between oral health and the pathogenesis of OM, highlighting the importance of oral health interventions for head and neck cancer patients.
