Young head and neck cancer patients are at increased risk of developing oral mucositis and trismus

The Trajectory of Oral Mucositis in Head and Neck Cancer Patients Undergoing Radiotherapy and its Influencing Factors

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.

Radiotherapy outcomes and risk factors for young patients with head-and-neck squamous cell carcinomas: a matched-pair analysis

BACKGROUND

Head-and-neck squamous cell carcinomas (HNSCC) exhibit significant variations in incidence and outcomes across age groups. There is conflicting data on the oncological outcomes of younger HNSCC patients ≤ 45 years. This study analyzed clinical characteristics, treatment-related toxicities and survival rates of young HNSCC patients treated with (chemo)radiotherapy.

METHODS

HNSCC patients ≤ 45 years treated with radiotherapy between 2009 and 2021 at two large cancer centers were analyzed and matched to a patient cohort > 45 years based on TNM and tumor localization. Overall (OS), progression-free (PFS) and metastasis-free (DMFS) survival and locoregional control (LRC) were compared and treatment-related toxicities were assessed.

RESULTS

99 patients were included in this analysis. Median OS of the young HNSCC cohort was 63 months. Daily alcohol consumption was identified as a key risk factor for reduced OS in the multivariate analysis. OS was similar in the young cohort compared to older patients, although the excess mortality risk compared to the sex- and age-matched general population amounted to 59-fold, while it was only 5.9-fold for patients ≥ 45 years. No significant differences were observed in PFS, LRC, or DMFS between age groups. Higher-grade chronic toxicities were moderate in young HNSCC patients.

CONCLUSIONS

Young HNSCC patients ≤ 45 years treated with (chemo)radiation have similar rates of oncological survival outcomes compared to older patients. While chronic toxicities from (chemo)radiation are low, further research is needed to explore the long-term quality-of-life.

Adverse drug reactions and drug-related problems with supportive care medications among the oncological population

AIM

The current study emphasizes the impact of adverse drug reactions (ADRs) and Drug-Related Problems (DRPs) caused by supportive care medications administered with chemotherapy.

METHOD

This is a longitudinal observational study carried out at the Ramaiah Medical College Hospital in Bengaluru, Karnataka, India, at the Department of Oncology. The data was recorded using a specifically created data collecting form. Based on the PCNE (Pharmaceutical Care Network Europe), DRPs are identified. The WHO probability scale, Modified Hartwig and Siegel for ADR severity assessment, Naranjo's algorithm for causality assessment, Rawlins and Thompson for predictability assessment, and Modified Shumock and Thornton for preventability assessment were all utilized. The OncPal guideline was considered in terms of the precision of supportive care medications regarding the reduction of ADRs in cancer patients.

RESULT

We enrolled 302 patients,166 (55%) female and 136 (45%) male (SD 14.378) (mean 49.97), patients with one comorbidity 59(19.6%) and multimorbidity (two or more) 45(14.9%), the DRPs identified were found to be 153 (50.6%); only P2 (safeties of drug therapy PCNE) were considered in this study. ADRs which are identified 175(57.9%) contributed/caused by the supportive care medications. WHO probability scale: 97 (32.1%) possible and 60 (19.9%) unlikely; Naranjo's algorithm: 97 (32.1%) unlikely and 69 (22.8%) possible; ADR severity assessment scale (Modified Hartwig and Siegel): 95 (31.5%) mild and 63 (20.9%) moderates; Rawlins and Thompson for determining predictability of an ADR: 33 (10.9%) predictable and 137 (45.5%) non-predictable; and Modified Shumock and Thornton for determining preventability of an ADR: 81 (26.8%) probably preventable and 90 (29.8%) non-preventable. The statistical comparison through preforming t-test and measuring Chi-Square between group with ADRs and without ADRs shows in some variables, significantly (Alcohol consumption status, P = .019) and Easter Cooperative Oncology Group (ECOG) performance status P < 0.001.

CONCLUSION

Comprehensive assessment of supportive medications in cancer patients would enhance the patient management and therapeutic outcome. The potential adverse drug reactions (ADRs) caused by supportive care medications can contribute to longer hospital stays and interact with the systemic anti-cancer treatment. The health care professionals should be informed to monitor the patients clinically administered with supportive medications.

Evidence summary on managing radiotherapy-induced oral mucositis in patients with head and neck cancer

Objective

To summarize the best evidence for managing radiotherapy-induced oral mucositis in patients with head and neck cancer, and improve the quality of care.

Methods

According to the "6S" evidence pyramid model, we searched local and other part of world published clinical guidelines, expert consensus, evidence summary, and systematic review. The literature quality assessment followed the Appraisal of Guidelines for Research and Evaluation (AGREE II). for guidelines, AMSTAR-2 for systematic reviews, and Joanna Briggs Institute (JBI) Evidence-Based Health Care Center's quality evaluation tool for expert opinions and expert consensus articles. The quality of other literature was evaluated according to the type of original literature. If there were any conflicts about the conclusions drawn from different sources of evidence, this study followed the principle of high-quality evidence priority and the latest published authoritative literature priority. The "JBI Evidence Pre-grading and Evidence Recommendation Level System 2014" was adopted for the evidence lacking a grading system. Quality evaluation, evidence extraction, and summary were performed by 2 or more researchers, combined with the advice of the head and neck cancer radiotherapy professionals.

Results

Finally, a total of ten pieces of literature were included. Twenty-two best evidence items for radiotherapy-induced oral mucositis management were summarized from six aspects, including multidisciplinary management, oral assessment, basic oral care, pain management, nutritional support, and application of honey or propolis.

Conclusions

This study provides clinical caregivers with the evidence-based measures on managing radiotherapy-induced oral mucositis. Clinical backgrounds, patients' condition, willingness, economy, and cost-effectiveness should be fully considered when promoting evidence transformation. Applying evidence-based approaches with high feasibility, strong appropriateness, clinical significance and high effectiveness could reduce the incidence of severe radiotherapy-induced oral mucositis in patients with head and neck cancer.

Predictive Factors for Chemoradiation-Induced Oral Mucositis and Dysphagia in Head and Neck Cancer: A Scoping Review

Despite advances in head and neck cancer treatment, virtually all patients experience chemoradiation-induced toxicities. Oral mucositis (OM) and dysphagia are among the most prevalent and have a systemic impact on patients, hampering treatment outcome and harming quality of life. Accurate prediction of severe cases is crucial for improving management strategies and, ultimately, patient outcomes. This scoping review comprehensively maps the reported predictors and critically evaluates the performance, methodology, and reporting of predictive models for these conditions. A total of 174 studies were identified from database searches, with 73 reporting OM predictors, 97 reporting dysphagia predictors, and 4 reporting both OM and dysphagia predictors. These predictors included patient demographics, tumor classification, chemoradiotherapy regimen, radiation dose to organs-at-risk, genetic factors, and results of clinical laboratory tests. Notably, many studies only conducted univariate analysis or focused exclusively on certain predictor types. Among the included studies, numerous predictive models were reported: eight for acute OM, five for acute dysphagia, and nine for late dysphagia. The area under the receiver operating characteristic curve (AUC) ranged between 0.65 and 0.81, 0.60 and 0.82, and 0.70 and 0.85 for acute oral mucositis, acute dysphagia, and late dysphagia predictive models, respectively. Several areas for improvement were identified, including the need for external validation with sufficiently large sample sizes, further standardization of predictor and outcome definitions, and more comprehensive reporting to facilitate reproducibility.

Proposal of a prophylactic photobiomodulation protocol for chemotherapy-induced oral and oropharyngeal mucositis: a randomized clinical trial

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.

Confounding factors in the assessment of oral mucositis in head and neck cancer

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.

Assessment of Relationship of ABO Blood Groups in Oral Cancer Patients - A Retrospective Study

Introduction:

India is a high-risk region for oropharyngeal cancer (OC) due to high prevalence of tobacco, betel nut, and alcohol and accounts for 30% of all new cases of oral cancer annually.

Materials and Methods:

Records of all 73 diagnosed cases of different types of OC and oropharynx patients were analyzed who reported in “Tobacco cessation center”’ of the Institute between January 2017 and December 2019. The patients’ demographic details, blood groups, oral habits, and clinicohistological records were obtained from the medical records available in the hospital.

Results:

OC incidence was 3.75 cases/year with male-to-female ratio 3.29:1. Mean age was 51.25 ± 13.6 years. The most common site of tumour presentation was mandibular alveolar ridge. Combined use of tobacco/betal nut/alcohol constituted the major cause for the development of oral squamous cell carcinoma (OSCC). Majority patients were presented in Stage II (43.8%). Histopathological reports were suggestive of maximally well-differentiated (52.1%) OSCC. People with blood group A+ve had 3.22 times higher risk of developing OSCC compared to people of other blood groups.

Discussion:

Male: female ratio was reported higher than in most of other studies. Mandibular alveolus was the most frequent site because most of the patients tend to keep the tobacco quid in the buccal vestibule with close proximity to alveolus. The relative downregulation of glycosyl transferase that is involved in the biosynthesis of A and B antigens as seen in association with tumour development could be the reason for increased OC reported in blood group A subjects.

Association and risk factors of healthcare-associated infection and burden of illness among chemotherapy-induced ulcerative mucositis patients

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.

Polymorphism of TNFRSF1 A may act as a predictor of severe radiation-induced oral mucositis and a prognosis factor in patients with head and neck cancer

OBJECTIVE

The aim of this study was to evaluate the relationship between single nucleotide polymorphism (SNP) (-135 T>C) of TNFRSF1 A and the frequency of occurrence and severity of oral mucositis (OM) in patients with head and neck cancer (HNC) treated with radiotherapy (RT).

STUDY DESIGN

This retrospective, cohort study included 60 patients with HNC treated with intensity-modulated radiation therapy (IMRT). TNFRSF1 A SNP analysis (-135 T>C) was performed by using molecular probes (TaqMan, ThermoFisher Scientific, Waltham, MA) in DNA isolated from peripheral blood (QIAamp DNA MiniKit; Qiagen, Germantown, MD).

RESULTS

CC genotype was related to 4.5-fold higher risk of grade 2 OM after the second week of RT. Similarly, CC carriers had a significantly higher risk of severe (grade 3) OM after the fourth (6-fold) and fifth (7.5-fold) weeks of RT. The CC genotype of the TNFRSF1 A gene was significantly correlated with a higher risk of shorter overall survival (OS) (> 37 months follow-up period; hazard ratio [HR] = 2.78).

CONCLUSIONS

SNP (-135 T>C) of the TNFRSF1 A gene may act as a predictor of OM occurrence in patients with HNC treated with IMRT. The studied SNP may also serve as a prognostic factor in such cases.
