Guidelines for the assessment of oral mucositis in adult chemotherapy, radiotherapy and haematopoietic stem cell transplant patients

Guidance on mucositis assessment from the MASCC Mucositis Study Group and ISOO: an international Delphi study

BACKGROUND

Mucositis is a common and highly impactful side effect of conventional and emerging cancer therapy and thus the subject of intense investigation. Although common practice, mucositis assessment is heterogeneously adopted and poorly guided, impacting evidence synthesis and translation. The Multinational Association of Supportive Care in Cancer (MASCC) Mucositis Study Group (MSG) therefore aimed to establish expert recommendations for how existing mucositis assessment tools should be used, in clinical care and trials contexts, to improve the consistency of mucositis assessment.

METHODS

This study was conducted over two stages (January 2022-July 2023). The first phase involved a survey to MASCC-MSG members (January 2022-May 2022), capturing current practices, challenges and preferences. These then informed the second phase, in which a set of initial recommendations were prepared and refined using the Delphi method (February 2023-May 2023). Consensus was defined as agreement on a parameter by >80% of respondents.

FINDINGS

Seventy-two MASCC-MSG members completed the first phase of the study (37 females, 34 males, mainly oral care specialists). High variability was noted in the use of mucositis assessment tools, with a high reliance on clinician assessment compared to patient reported outcome measures (PROMs, 47% vs 3%, 37% used a combination). The World Health Organization (WHO) and Common Terminology Criteria for Adverse Events (CTCAE) scales were most commonly used to assess mucositis across multiple settings. Initial recommendations were reviewed by experienced MSG members and following two rounds of Delphi survey consensus was achieved in 91 of 100 recommendations. For example, in patients receiving chemotherapy, the recommended tool for clinician assessment in clinical practice is WHO for oral mucositis (89.5% consensus), and WHO or CTCAE for gastrointestinal mucositis (85.7% consensus). The recommended PROM in clinical trials is OMD/WQ for oral mucositis (93.3% consensus), and PRO-CTCAE for gastrointestinal mucositis (83.3% consensus).

INTERPRETATION

These new recommendations provide much needed guidance on mucositis assessment and may be applied in both clinical practice and research to streamline comparison and synthesis of global data sets, thus accelerating translation of new knowledge into clinical practice.

Analysis of the association between salivary proteins and oral mucositis in patients with head and neck cancer undergoing IMRT: a longitudinal study

INTRODUCTION

This longitudinal study assessed the association between salivary protein composition and the clinical onset/severity of oral mucositis (OM) in patients with head and neck tumours treated with intensity-modulated-radiotherapy (IMRT).

METHODS

Saliva samples/clinical data were obtained from 40 head and neck cancer patients treated at Guy's Hospital before -IMRT(T0) and after-IMRT (T1 = 6 m, T2 = 12 m) (ethics approval/consent). Salivary flow rate, total protein concentration, and secretion rate were determined from saliva samples and compared with pre-treatment values. OM was assessed, total/specific salivary proteins, including mucin 5B and 7, IgA, cystatin-S, albumin, and α-amylase, were quantified.

RESULTS

95% patients experienced OM during IMRT, with 33 subjects reaching grade 2&3. At T1, there was a significant reduction in salivary flow rate, total protein secretion rate, α-amylase and cystatin-S compared to baseline. Remarkably IMRT did not significantly alter mucin 5B and 7, or the IgA secretion rate at any time point. At T1, all the analyzed proteins were associated with the OM outcomes. In addition, there was a significant inverse correlation between IgA concentration at T0 and the severity of OM during IMRT.

CONCLUSION

This study revealed significant associations between several salivary proteins and OM in patients with head and neck cancer undergoing IMRT. Further longitudinal studies are needed to confirm these results.

CLINICAL SIGNIFICANCE

The study contributes to the understanding of certain salivary proteins association with OM. This could be the first step towards identifying potential salivary markers that could offer perspectives for personalized medicine approaches to improve their quality of life (QoL).

RESEARCH QUESTION

What is the association between salivary proteins and the occurrence and severity of OM in head and neck cancer patients?

AIM

To assess the association between salivary protein composition with the clinical onset/severity of oral mucositis (OM) in head and neck cancer patients treated with intensity modulated radiotherapy.

NULL HYPOTHESIS

There is no association between salivary proteins and onset/severity of OM in HNC patients.

L-Glutamine and Survival of Patients with Locally Advanced Head and Neck Cancer Receiving Chemoradiotherapy

We previously reported that L-glutamine reduces the severity of mucositis caused by chemoradiotherapy in patients with head and neck cancer. However, the impact of glutamine on the anti-tumor effect of chemoradiotherapy remains controversial. This study, which included 40 patients, investigated whether L-glutamine influences survival. Radiation therapy (total: 66 or 70 Gy), cisplatin, and docetaxel were co-administered for a period of 6 weeks. Patients were randomly assigned to receive either glutamine (glutamine group, n = 20) or placebo (placebo group, n = 20) during the entire course of chemoradiotherapy. We compared the overall survival and progression-free survival rates between the two groups. At 5-year follow-up, 16 (80%) and 13 (72%) patients in the glutamine and placebo groups, respectively, survived (with no significant difference in overall survival [glutamine group: 55.2 ± 12.7 months vs. placebo group: 48.3 ± 21.3 months]). A total of 14 (70%) and 12 (67%) patients in the glutamine and placebo groups, respectively, did not experience disease progression (with no significant difference in progression-free survival [glutamine group: 46.7 ± 19.5 months vs. placebo group: 43.6 ± 25.2 months]). These findings indicate that L-glutamine does not influence the survival of patients with locally advanced head and neck cancer receiving chemoradiotherapy.

Protective effect of cryotherapy against oral mucositis among allogeneic hematopoietic stem cell transplant recipients using melphalan-based conditioning

PURPOSE

Oral cryotherapy is an effective method to prevent oral mucositis (OM) induced by chemotherapeutic agents, such as melphalan (Mel). However, there is limited data about cryotherapy in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients; thus, the current study aimed to examine the efficacy of cryotherapy among allo-HSCT recipients treated with Mel-containing regimens.

METHODS

Medical records of 78 consecutive allo-HSCT recipients were retrospectively analyzed. Baseline characteristics and clinical courses between the patients who received cryotherapy (cryotherapy group, n = 42) and those who did not (control group, n = 36) were compared, especially focusing on methotrexate (MTX) use as a part of graft-versus-host disease (GVHD) prophylaxis.

RESULTS

Binary logistic regression analysis revealed that a higher dose of Mel (OR, 3.82; 95%CI, 1.085-13.46; P = 0.037) or MTX use (OR, 7.61; 95% CI, 2.41-23.97; P < 0.001) was associated with the incidence of OM. MTX use was also significantly associated with the duration of OM (β = 0.515; 95% CI, 9.712-21.636; P < 0.001). Among 31 patients without MTX use, cryotherapy was associated with a significant reduction of OM development (0% in the cryotherapy group vs 35% in the control group, P = 0.021). We did not find such an association in 47 patients with MTX use.

CONCLUSION

Cryotherapy was useful to prevent the incidence of OM in allo-HSCT recipients in the cases without MTX for GVHD prophylaxis.

Application of big data analyses to compare the impact of oral and gastrointestinal mucositis on risks and outcomes of febrile neutropenia and septicemia among patients hospitalized for the treatment of leukemia or multiple myeloma

PURPOSE

Oral ulcerative mucositis (UM) and gastrointestinal mucositis (GIM) have been associated with increased likelihood of systemic infection (bacteremia and sepsis) in patients being treated for hematological malignancies. To better define and contrast differences between UM and GIM, we utilized the United States 2017 National Inpatient Sample and analyzed patients hospitalized for the treatment of multiple myeloma (MM) or leukemia.

METHODS

We utilized generalized linear models to assess the association between adverse events-UM and GIM-among hospitalized MM or leukemia patients and the outcome of febrile neutropenia (FN), septicemia, burden of illness, and mortality.

RESULTS

Of 71,780 hospitalized leukemia patients, 1255 had UM and 100 GIM. Of 113,915 MM patients, 1065 manifested UM and 230 had GIM. In an adjusted analysis, UM was significantly associated with increased risk of FN in both the leukemia (aOR = 2.87, 95% CI = 2.09-3.92) and MM cohorts (aOR = 4.96, 95% CI = 3.22-7.66). Contrastingly, UM had no effect on the risk of septicemia in either group. Likewise, GIM significantly increased the odds of FN in both leukemia (aOR = 2.81, 95% CI = 1.35-5.88) and MM (aOR = 3.75, 95% CI = 1.51-9.31) patients. Similar findings were noted when we restricted our analysis to recipients of high-dose condition regimens in preparation for hematopoietic stem-cell transplant. UM and GIM were consistently associated with higher burden of illness in all the cohorts.

CONCLUSION

This first use of big data provided an effective platform to assess the risks, outcomes, and cost of care of cancer treatment-related toxicities in patients hospitalized for the management of hematologic malignancies.

Psychometric evaluation of Oral Mucositis Daily Questionnaire: A cross-cultural adaptation of the Malay version in multiethnic adult autologous stem cell transplant

Objective

Mucositis is one of the most feared side effects of cancer treatment. Psychometric analysis of a patient self-assessment score, the oral mucositis daily questionnaire in Malay (OMDQ-Mal) and its construct validity by means of confirmatory factor analysis (CFA) is lacking. This research aimed to test the validity and reliability of OMDQ-Mal.

Methods

A total of 114 autologous stem-cell transplantation patients aged ≥ 18 years old at a national hematology center in Malaysia from April 2019 to December 2020 completed OMDQ-Mal concurrently with physician scores. Internal consistency and reproducibility were determined by Cronbach alpha and intraclass correlation coefficient, respectively. Correlations with physician scores were determined by Spearman correlation. Discriminative validity and construct validity were determined by Mann-Whitney U and CFA, respectively.

Results

OMDQ-Mal demonstrated high internal consistency (α ​= ​0.874). Test-retest reliability between paired days were moderate to excellent (95% CI ​= ​0.676-0.953). Items in OMDQ-Mal had moderate to strong correlations with physician scores (ρ ​= ​0.503-0.721). Discriminative validity indicated that the scores of scales were significantly different between participants with severe and mild conditions. Construct validity results of loading factors 0.708-0.952; composite reliability 0.879-0.974; average variant extracted 0.710-0.841; and heterotrait-monotrait ratio 0.528 established the convergent and divergent validity.

Conclusions

In conclusion, the OMDQ-Mal, which captured important quality of life responses, demonstrated adequate validity and reliability. This was supported by a two-component model CFA. The strong correlation of OMDQ-Mal with both physician scores indicated its potential as a comprehensive patient-reported outcome measure of mucositis of the entire alimentary tract.

Stem cell transplantation patients receiving a novel oral care protocol for oral mucositis prevention and treatment: patient-reported outcomes and quality of life

BACKGROUND

Oral mucositis (OM) is one of the most debilitating effects of toxicity due to hematopoietic stem cell transplantation (HSCT) conditioning regimens. The aim of this secondary analysis of the data of a phase II study designed to assess the efficacy of a novel oral care protocol containing bovine colostrum and aloe vera to prevent oral mucositis was to compare outcomes reported by patients with those collected by healthcare professionals (HCPs).

METHOD

Data on oral mucositis severity, duration, time of onset and related pain were collected from patients using the Oral Mucositis Daily Questionnaire (OMDQ). HCPs assessed the same outcomes using the World Health Organization oral mucositis scale and pain numerical rating scale. Quality of life was assessed with the 3-level EuroQol-5 dimensions.

RESULTS

Fifty-nine autologous/allogeneic graft patients were recruited, 46 of whom (78.0%) experienced OM. Mean onset was 9.1 (SD ± 3.5) days after conditioning initiation, mean duration was 10.4 (SD ± 4.3) days, and the average maximum pain score was 3.7 (SD ± 2.7). Self-administration of the OMDQ detected oral symptoms at least 1 day sooner compared to objective assessments (p = 0.025). Significant differences were observed between the patient-reported and the HCP-assessment data on oral mucositis severity grading distribution (p < 0.0001) and highest pain score (p < 0.0001). Quality of life score variations were correlated with changes in oral mucositis severity during patients' hospital stay.

CONCLUSIONS

Further studies are necessary to improve the understanding of these findings; a randomised controlled trial is being set up at our institution.

A real-world accuracy of oral mucositis grading in patients undergoing hematopoietic stem cell transplantation

PURPOSE

Oral mucositis is a common complication in patients undergoing hematopoietic stem cell transplantation. Accurate oral mucositis grading is essential for both clinical practice and oral mucositis research. This study aimed to evaluate the accuracy of daily oral mucositis grading by nurses in a tertiary hospital in Australia.

METHODS

A retrospective study was undertaken to review the daily patient oral assessment record, including diet, pain, erythema, ulceration and the oral mucositis grade based on World Health Organization (WHO) oral mucositis grading scale. The accuracy of the grade was determined by the observations recorded, and reasons for inaccuracy were documented. Any repetition of the same error in the same patient was noted.

RESULTS

In total, 6841 oral assessments in 373 patients, conducted between 2017 and 2020, were reviewed. A total of 70% (N = 4781) were graded correctly. Of these, 64% (N = 3043) were grade 0. When the grade 0 scores were excluded, the accuracy of grading was reduced to 46% (N = 1738). Common reasons for incorrect grading included: unable to grade due to diet not specified, no ulceration and no pain was scored grade 1, no ulceration was scored as grade 2-4, oral intake was not taken into account, and pain without ulcer was scored 0. A total of 77% of the errors were repeated in the same patient on consecutive days.

CONCLUSIONS

Our results suggest there is frequent inaccurate evaluation of oral mucositis and a need for nurse training to accurately assess oral mucositis.

Managing the effects of cancer and cancer treatments on patients' nutritional status

Adequate nutrition is a basic requirement of the human body, supporting cell growth and optimal organ function. The nutritional requirements of patients with cancer can increase due to systemic inflammatory responses caused by cancer and cancer treatments. Nurses have an important role in providing nutritional interventions to patients undergoing treatment for cancer, through education and person-centred nutritional care. This article examines which nutritional interventions provided by nurses can relieve symptoms and side effects, improve nutritional status and enhance quality of life in patients with cancer.

Radiation-Induced Oral Mucositis in Head and Neck Cancer Patients. Five Years Literature Review

Backround: Radiation-induced oral mucositis consists of a series of relatively frequent side effects after head and neck cancer radiotherapy and has an adverse impact on both regular treatment process and the quality of life of patients.

OBJECTIVE

The purpose of the present review is to optimize the current management of radiation-induced oral mucositis in head and neck cancer patients.

METHODS

PubMed database research was performed on articles published since 2015 that demonstrated efficacy in the management of radiation-induced oral mucositis in head and neck cancer patients. The study selection included observational, prospective, comparative, randomized, double- blind, placebo-controlled or uncontrolled, and retrospective studies, as well as systematic reviews and metanalyses.

RESULTS

From the 931 citations obtained from the search, only 94 articles met the inclusion criteria, including mucosal protectants, anti-inflammatory agents, growth factors, and various miscellaneous and natural agents. Several methods, including both pharmacological and natural agents, have been proposed for the management of oral mucositis. In addition to the already known interventions with strong evidence, according to the Multinational Association of Supportive Care in Cancer and he International Society of Oral Oncology guidelines, further agents have been used. However, a great number of them lack clear evidence, which surely requires the design of more controlled clinical trials for a better assessment of the ideal methods.

CONCLUSION

The management of oral mucositis constitutes an active area of research. In light of these results, it is aimed to illustrate those treatment strategies that are most effective regarding the treatment approach of oral mucositis.

Supportive care during pediatric hematopoietic stem cell transplantation: beyond infectious diseases. A report from workshops on supportive care of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Hematopoietic stem cell transplantation (HSCT) is currently the standard of care for many malignant and nonmalignant blood diseases. As several treatment-emerging acute toxicities are expected, optimal supportive measurements critically affect HSCT outcomes. The paucity of good clinical studies in supportive practices gives rise to the establishment of heterogeneous guidelines across the different centers, which hampers direct clinical comparison in multicentric studies. Aiming to harmonize the supportive care provided during the pediatric HSCT in Europe, the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) promoted dedicated workshops during the years 2017 and 2018. The present paper describes the resulting consensus on the management of sinusoidal obstructive syndrome, mucositis, enteral and parenteral nutrition, iron overload, and emesis during HSCT.

Oral pain associated with cancer therapy, a pain medicine perspective

Cancer therapy-induced oral mucositis (CTIOM) can cause intolerable oral pain resulting in difficulty in chewing, swallowing and speaking. Thus, leading to patients requiring aggressive measures, such as parenteral feeding, the placement of gastric feeding tubes and discontinuation of oncologic treatments. Although, pain is the debilitating symptom, current efforts seem to focus independently in the histological damage, not in pain and symptom care. Current strategies for managing pain from CTIOM entail maintaining oral hygiene and the use of oral rinses, topical anesthetics, prophylactic antimicrobials and systemic analgesics such as opioids. Novel therapies, such as methylene blue oral rinse, are being investigated, with positive outcomes. Therefore, there is a need to identify treatment modalities for pain of CTIOM. Ideally, this should be noninvasive, safe and cost-effective, while providing sustained analgesia.

Efficacy of selective digestive decontamination in patients with multiple myeloma undergoing high-dose chemotherapy and autologous stem cell transplantation

Selective digestive decontamination (SDD) with the oral, non-absorbable antimicrobial substances gentamicin, vancomycin and amphotericin B was optionally used at our institution to reduce the risk of gastrointestinal tract derived infections in multiple myeloma (MM) patients undergoing high-dose chemotherapy with subsequent autologous stem cell transplantation (HDCT/ASCT). The majority of patients received sulfamethoxazole-trimethoprim as pneumocystis pneumonia prophylaxis. From 203 patients receiving their first HDCT/ASCT between 2009 and 2015, we compared retrospectively 90 patients receiving SDD to 113 patients not receiving SDD. The administration of SDD was associated with a reduction of bacterial infections after HDCT/ASCT (overall: 8% versus 24%, p = .002; gram-negative pathogens: 1% versus 11%, p = .006) and less use of systemic antibiotics (62% versus 77%, p = .022). Omission of SDD was an independent risk factor for developing neutropenic fever and bloodstream infections. SDD could be an option to reduce bacterial infections in patients undergoing HDCT/ASCT that needs to be tested in prospective trials.

Elemental Diet Accelerates the Recovery From Oral Mucositis and Dermatitis Induced by 5-Fluorouracil Through the Induction of Fibroblast Growth Factor 2

Mucositis and dermatitis induced by anticancer agents are common complications of anticancer therapies. In this study, we evaluated the efficacy of Elental (Ajinomoto Pharmaceutical Ltd, Tokyo, Japan), an elemental diet with glutamine in the treatment of 5-fluorouracil (5-FU)-induced oral mucositis and dermatitis in vivo and tried to clarify the underlying mechanisms of its action. Oral mucositis and dermatitis was induced through a combination of 5-FU treatment and mild abrasion of the cheek pouch in hamsters and the dorsal skin in nude mice respectively. These animals received saline, dextrin or Elental suspension (18 kcal/100 g) by a gastric tube daily until sacrifice. Elental reduced oral mucositis and dermatitis more effectively than dextrin in the animal model. Moreover, growth facilitating effects of Elental on HaCaT cells were examined in vitro. MTT assay, wound healing assay, and migration assay revealed that Elental could enhance the growth, invasion, and migration ability of HaCaT. ELISA and Western blotting showed upregulated FGF2 in Elental-treated HaCaT. These findings suggest that Elental is effective for the treatment of mucositis and dermatitis, and may accelerate mucosal and skin recovery through FGF2 induction and reepithelization.

Radiation-Induced Oral Mucositis

Radiation-induced oral mucositis (RIOM) is a major dose-limiting toxicity in head and neck cancer patients. It is a normal tissue injury caused by radiation/radiotherapy (RT), which has marked adverse effects on patient quality of life and cancer therapy continuity. It is a challenge for radiation oncologists since it leads to cancer therapy interruption, poor local tumor control, and changes in dose fractionation. RIOM occurs in 100% of altered fractionation radiotherapy head and neck cancer patients. In the United Sates, its economic cost was estimated to reach 17,000.00 USD per patient with head and neck cancers. This review will discuss RIOM definition, epidemiology, impact and side effects, pathogenesis, scoring scales, diagnosis, differential diagnosis, prevention, and treatment.

A novel lozenge containing bupivacaine as topical alleviation of oral mucositis pain in patients with head and neck cancer: a pilot study

Introduction: Oral mucositis induces severe oral pain in head and neck cancer patients. There is at this point no effective pain treatment without considerable side effects.

Objective: The aim of this pilot study was to investigate pain reduction in oral cavity and pharynx in patients with head and neck cancer (HNC) with oral mucositis, the location of anesthetic effect, and duration of pain relief, after a single-dose administration of a 25 mg bupivacaine lozenge.

Methods: Ten patients with HNC suffering from oral mucositis pain were included. The patients assessed pain in the oral cavity and pharynx on a visual analogue scale (from 0 to 100 mm) at baseline and up to 3 hours after the lozenge was dissolved. Possible adverse events were registered.

Results: The baseline pain was 51 mm (range: 30–73 mm) in the oral cavity and 58 mm (range: 35–70 mm) in the pharynx. When the lozenge was dissolved, both oral (−27 mm; range: −3 to −52 mm; P = 0.0003) and pharynx pain (−20 mm; range: −3 to −45 mm; P = 0.008) were significantly reduced. After 180 minutes, the mean reduction in pain was significant in the oral cavity (−18 mm; range: −8 to −30 mm; P < 0.0001) but not in the pharynx (−8 mm; range: +4 to −23 mm; P = 0.12). No adverse events were observed.

Conclusion: The results indicate that the bupivacaine lozenge has a clinically significant and long-lasting pain-relieving effect on pain because of oral mucositis in patients with HNC.

Mineral derivatives in alleviating oral mucositis during cancer therapy: a systematic review

Objectives. Oral mucositis (mouth ulcers) is a cancer therapy side effect. Costly treatment interventions are often neglected in favor of cost-effective agents. This review assessed the general efficacy of mineral derivatives (a cost-effective agent) in alleviating oral mucositis (OM) during cancer therapy compared to the standard care, or placebo-including a decision tree to aide healthcare workers. Data Sources. Electronic searches of MEDLINE via OVID, EMBASE, CENTRAL, CANCERLIT via PubMed, and CINAHL via EBSCO (year 2000 to 11 September 2014) were undertaken for randomised controlled trials. A meta-search strategy extracted content from aggregate online databases. Review Methods. Randomized controlled trials were assessed (participants, intervention, outcome, results, and risk of bias) for inclusion. The author abstracted binary and continuous data synthesised to Hedges' g in a random effects model. The primary outcome measures were severity (incidence of peak oral mucositis, duration of oral mucositis, and time to onset); secondary outcome measures were the incidence of pain, and analgesic use. Serum mineral levels, total parenteral nutrition, and adverse events were discussed. The decision tree was mapped using sensitivity, specificity, pre-test and post-test Bayesian probability. Results. 1027 citations were identified and 16 studies were included (n = 1120; mean age 49 years). Cancer therapies consisted of chemotherapy, radiotherapy, chemo-radiotherapy, or hematopoietic stem cell transplantation. Outcome mineral derivatives were zinc (n = 549), calcium phosphate (n = 227), povidone-iodine (n = 228), or selenium (n = 116). Severity was measured across variable OM grading systems: In 13 studies, individuals in treatment groups (n = 958) experienced peak OM less than controls (g = -0.47, 95% CI -0.7 to -0.2, p = 0.0006); time to OM onset was significantly delayed in treatment than controls (g = -0.51, 95% CI-0.8 to -0.2, p = 0.0002; five studies); OM mean duration, pain incidences, or analgesics use was not significant. The decision analysis favored selenium. Conclusion. The general positive effect trend suggests individuals taking mineral derivatives during cancer therapies are less likely to experience peak OM than those without. However, significant bias and heterogeneity indicates the need for developing further methods in account of diverse protocols and include novel recordings (serum mineral levels and cell signals) in estimating a uniform true effect.

Basic oral care for hematology-oncology patients and hematopoietic stem cell transplantation recipients: a position paper from the joint task force of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) and the European Society for Blood and Marrow Transplantation (EBMT)

PURPOSE

Hematology-oncology patients undergoing chemotherapy and hematopoietic stem cell transplantation (HSCT) recipients are at risk for oral complications which may cause significant morbidity and a potential risk of mortality. This emphasizes the importance of basic oral care prior to, during and following chemotherapy/HSCT. While scientific evidence is available to support some of the clinical practices used to manage the oral complications, expert opinion is needed to shape the current optimal protocols.

METHODS

This position paper was developed by members of the Oral Care Study Group, Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) and the European Society for Blood and Marrow Transplantation (EBMT) in attempt to provide guidance to the health care providers managing these patient populations.

RESULTS

The protocol on basic oral care outlined in this position paper is presented based on the following principles: prevention of infections, pain control, maintaining oral function, the interplay with managing oral complications of cancer treatment and improving quality of life.

CONCLUSION

Using these fundamental elements, we developed a protocol to assist the health care provider and present a practical approach for basic oral care. Research is warranted to provide robust scientific evidence and to enhance this clinical protocol.

L-glutamine decreases the severity of mucositis induced by chemoradiotherapy in patients with locally advanced head and neck cancer: a double-blind, randomized, placebo-controlled trial

The incidence of severe mucositis in the oral cavity, pharynx and larynx is high among patients with head and neck cancer (HNC) receiving chemoradiotherapy (CRT), resulting in significant pain and impairment of quality of life. The present study investigated whether L-glutamine (glutamine) decreases the severity of mucositis in the oral cavity, pharynx and larynx induced by CRT. This double-blind, randomized, placebo-controlled trial included 40 untreated patients with squamous cell carcinoma of the nasopharynx, oropharynx, hypopharynx or larynx. Patients received 66 or 70 Gy of total radiation at the rate of 2 Gy/fraction daily and 5 fractions/week. Cisplatin (20 mg/m²) and docetaxel (10 mg/m²) were intravenously co-administered once a week for 6 weeks. Patients were randomized to orally receive either glutamine (group G) or placebo (group P) at a dose of 10 g 3 times a day throughout the CRT course. Mucositis was assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. The primary end point was mucositis severity. Mucositis developed in all patients. A maximal mucositis grade of G4 was observed in 0 and 25% group G and P patients, respectively, while that of G2 was observed in 10 and 0% group G and P patients, respectively (p=0.023). Glutamine significantly decreased the maximal mucositis grade (group G, 2.9±0.3; group P, 3.3±0.4; p=0.005) and pain score at weeks 4, 5 and 6. Glutamine significantly decreased mucositis severity in the oral cavity, pharynx and larynx induced by CRT in patients with HNC.

Clinical practice guidelines and consensus statements in oncology--an assessment of their methodological quality

BACKGROUND

Consensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.

METHODS

Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.

FINDINGS

Thirty-four consensus statements and 67 clinical practice guidelines were evaluated. The rigour of development score for consensus statements over the three journals was 32% lower than that of clinical practice guidelines. The editorial independence score was 15% lower for consensus statements than clinical practice guidelines. One journal scored consistently lower than the others over both domains. No journals adhered to all the items related to the transparency of document development. One journal's consensus statements endorsed a product made by the sponsoring pharmaceutical company in 64% of cases.

CONCLUSION

Guidance documents are an essential part of oncology care and should be subjected to a rigorous and validated development process. Consensus statements had lower methodological quality than clinical practice guidelines using AGREE II. At a minimum, journals should ensure that that all consensus statements and clinical practice guidelines adhere to AGREE II criteria. Journals should consider explicitly requiring guidelines to declare pharmaceutical company sponsorship and to identify the sponsor's product to enhance transparency.

A traditional Japanese medicine--Hangeshashinto (TJ-14)--alleviates chemoradiation-induced mucositis and improves rates of treatment completion

PURPOSE

Oral mucositis induced by radiation or chemoradiation can cause devastating quality of life issues for patients undergoing treatment for head and neck cancer. In this study, we investigated the efficacy of a traditional Japanese medicine-Hangeshashinto (TJ-14)-for (chemo)radiation-induced oral mucositis.

METHODS

Eighty patients who underwent whole neck radiation of >60 Gy with or without chemotherapy (high-dose cisplatin or low-dose docetaxel) were enrolled in this retrospective study; 40 had received TJ-14 during treatment, and 40 had not (controls). Factors related to alleviation of oral mucositis were identified by multivariate logistic regression analysis. Rates of completion of (chemo)radiation treatments were compared between the patients who received TJ-14 and the control group according to the treatment regimen. The comparison of the nutrition status between groups was also performed.

RESULTS

Multivariate analysis indicated that the use of TJ-14 (p = 0.019), gender (p = 0.024), and primary tumor location (p = 0.028) were significant factors associated with the severity of oral mucositis. TJ-14 was associated with a significantly improved rate of completion of chemoradiation with cisplatin (p = 0.002). In the investigation of nutritional status, only serum albumin was significantly maintained better in the TJ-14 group than the control group in terms of mean change before and after (chemo)radiation (p = 0.024).

CONCLUSIONS

The present study indicates that TJ-14 is effective for ameliorating oral mucositis induced by (chemo)radiation in patients with head and neck cancers. TJ-14 was associated with improved completion rates of chemoradiation treatments with cisplatin. A randomized controlled trial is necessary to confirm the efficacy of TJ-14 for chemoradiation-induced mucositis in head and neck cancer patients.

Assessment of cancer therapy-induced oral mucositis using a patient-reported oral mucositis experience questionnaire

Objectives

Treatment of oral mucositis (OM) is challenging. In order to develop and test useful treatment approaches, the development of reliable, reproducible and simpler methods than are currently available for assessment of OM is important. A Patient-Reported Oral Mucositis Symptom (PROMS) scale was assessed in patients with head and neck cancer to determine if the patient-reported OM experience, as determined by using the PROMS scale, correlate with OM assessed by clinician-based scoring tools.

Materials and Methods

Fifty patients with head and neck cancer and undergoing radiotherapy consented to participate. They were examined before cancer treatment and twice weekly during 6–7 weeks of therapy and once 4–6 weeks after therapy. Signs of OM were evaluated using the 3 clinician-based scoring tools; NCI-CTCAE v.3, the OMAS criteria and the Total VAS-OMAS. The participants' OM experiences were recorded using PROMS-questionnaires consisting of 10 questions on a visual analogue scale. Spearman rank correlation test were applied between the PROMS scale values and the clinician-determined scores. Repeated measures mixed linear models were applied to appraise the strengths of correlation at the different time points throughout the observation period.

Results

Thirty-three participants completed all stages of the study. The participant experience of OM using the PROMS scale demonstrates good correlations (Spearman's Rho 0.65–0.78, p<0.001) with the clinician-determined scores on the group level over all time points and poor to good correlations (Spearman's Rho -0.12–0.70, p<0.001) on the group level at different time points during and after therapy. When mouth opening was problematic, i.e. during the 6^th and 7^th week after commencing cancer treatment, the Spearman's Rho varied between 0.19 and 0.70 (p<0.001).

Conclusion

Patient experience of OM, as reported by the PROMS scale may be a feasible substitute for clinical assessment in situations where patients cannot endure oral examinations.

Acute mucosal radiation reactions in patients with head and neck cancer. Patterns of mucosal healing on the basis of daily examinations

PURPOSE

The goal of this research was to evaluate the healing processes of acute mucosal radiation reactions (AMRR) in patients with head and neck cancer.

MATERIALS AND METHODS

In 46 patients with oral and oropharyngeal cancer patients irradiated with conventional (n = 25) and accelerated (n = 21) dose fractionation AMRR was evaluated daily during and after radiotherapy. Complex of morphological and functional symptoms according to the Dische score were collected daily until complete healing.

RESULTS

Duration of healing after the end of radiotherapy ranged widely (12-70 days). It was on the average 8 days longer for accelerated than for conventional radiotherapy (p = 0.016). Duration of dysphagia was also longer for accelerated irradiation (11 days, p = 0.027). Three types of morphological symptoms were observed as the last symptom at the end of AMRR healing: spotted and confluent mucositis, erythema, and edema. Only a slight correlation between healing duration and area of irradiation fields (r = 0.23) was noted. In patients with confluent mucositis, two morphological forms of mucosal healing were observed, i.e., marginal and spotted. The spotted form was noted in 71% of patients undergoing conventional radiotherapy and in 38% of patients undergoing accelerated radiotherapy. The symptoms of mucosal healing were observed in 40% patients during radiotherapy.

CONCLUSION

The wide range of AMRR healing reflects individual potential of mucosa recovery with longer duration for accelerated radiotherapy. Two morphological forms of confluent mucositis healing were present: marginal and spotted. Healing of AMRR during radiotherapy can be observed in a significant proportion of patients.

Sodium Bicarbonate Solution versus Chlorhexidine Mouthwash in Oral Care of Acute Leukemia Patients Undergoing Induction Chemotherapy: A Randomized Controlled Trial

PURPOSE

The objective of this study was to compare the effectiveness of sodium bicarbonate (SB) solution with chlorhexidine (CHX) mouthwash in oral care of acute leukemia patients under induction chemotherapy.

METHODS

Forty-eight patients were randomly selected and assigned to an SB solution group or CHX-based product group according to acute myelogenous leukemia or acute lymphoblastic leukemia. Patients were asked to rinse their mouth four times a day from the day before chemotherapy started until discharge. The World Health Organization mucositis grade, patient-reported Oral Mucositis Daily Questionnaire, and clinical signs associated with infection were assessed on a daily basis. The oral microbial count was assessed on a weekly basis from the 1st day of chemotherapy started to the 28th day or to the day of discharge from the hospital.

RESULTS

Of all the patients in the SB group, 25.0% developed ulcerative oral mucositis, whereas 62.5% in the CHX group did. The onset of oral mucositis was later in the SB group than the CHX group. The oral bacterial colonization in the SB group was significantly higher than that in the CHX group, but clinical signs associated with infection did not differ in both groups.

CONCLUSION

As a result of this study, it was found that oral care by SB solution for acute leukemia patients undergoing chemotherapy was an effective intervention to improve oral health.

Palifermin decreases severe oral mucositis of patients undergoing postoperative radiochemotherapy for head and neck cancer: a randomized, placebo-controlled trial

PURPOSE

Radiochemotherapy of head and neck cancer causes severe mucositis in most patients. We investigated whether palifermin reduces this debilitating sequela.

METHODS

We conducted a multicenter, double-blind, randomized, placebo-controlled trial in 186 patients with stages II to IVB carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx. Patients received 60 or 66 Gy after complete (R0) or incomplete resection (R1), respectively, at 2 Gy/fraction and five fractions per week. Cisplatin 100 mg/m(2) was administered on days 1 and 22 (and on day 43 with R1). Patients were randomly assigned to receive weekly palifermin 120 μg/kg or placebo from 3 days before and continuing throughout radiochemotherapy. Trained evaluators performed oral assessments twice weekly. The primary end point was the incidence of severe oral mucositis (WHO grades 3 to 4). Overall survival and time to locoregional progression were also assessed. Analysis was by intention to treat.

RESULTS

Severe oral mucositis was seen in 47 (51%) of 92 patients administered palifermin and 63 (67%) of 94 administered placebo (P = .027). Palifermin decreased the duration (median, 4.5 v 22.0 days) and prolonged the time to develop (median, 45 v 32 days) severe mucositis. Neither patient-reported mouth and throat soreness scores nor treatment breaks differed between treatment arms. After median follow-up of 32.8 months, 23 deaths (25%) had occurred in both treatment arms, and disease had recurred in 25 (27%) and 22 (24%) of palifermin- and placebo-treated patients, respectively.

CONCLUSION

Palifermin reduced the occurrence of severe oral mucositis in patients with head and neck cancer undergoing postoperative radiochemotherapy. Additional clinical exploration of palifermin with postoperative radiochemotherapy would be useful.

Mucositis in malignant hematology

Mucosal barrier injury (MBI), also known as mucositis, is the result of the cytotoxic effects of many treatments given for hematological malignancies (HMs) and represents a major source of potentially devastating clinical complications and negative consequences afflicting the patient's management, such as a longer hospitalization, the need of analgesic and total parenteral nutrition use, and increased costs. The available measures for the prevention and treatment of MBI have been substantially limited to the control of pain, infection, bleeding and nutrition. However, in the last decade, a better insight into the complex pathogenesis of MBI has led to the development of novel therapeutic options, such as palifermin, which has been one of the major breakthroughs in the management of this condition, potentially allowing a targeted approach to MBI. Nevertheless, and despite these significant advances, MBI still remains a significant clinical problem in the management of HM and an important burden of sufferance for afflicted patients.

Nutritional screening and early treatment of malnutrition in cancer patients

BACKGROUND: Malnutrition is a frequent complication in patients with cancer and can negatively affect the outcome of treatments. On the other hand, side effects of anticancer therapies can also lead to inadequate nutrient intake and subsequent malnutrition. The nutritional screening aims to identify patients at risk of malnutrition for prompt treatment and/or careful follow-up. METHODS AND RESULTS: This manuscript highlights the need of an interdisciplinary approach (oncologist, nutritionist, dietitian, psychologist, etc.) to empower patients who are experiencing loss of physiological and biological function, fatigue, malnutrition, psychological distress, etc., as a result of cancer disease or its treatment, and maintain an acceptable quality of life. CONCLUSIONS: It is necessary to make all healthcare professionals aware of the opportunity to identify cancer patients at risk of malnutrition early in order to plan the best possible intervention and follow-up during cancer treatment and progression.

A systematic review of oral assessment instruments: what can we recommend to practitioners in children's and young people's cancer care?

BACKGROUND

Observing and recording the signs and symptoms of oral mucositis are an important part of oral care, essential to the prevention and treatment of mucositis. Structured oral assessment enables a more informed and accurate identification of signs and symptoms and will enable early and individualized interventions.

OBJECTIVE

A United Kingdom-based mouth-care group conducted a systematic review of the published literature through to March 2004 and repeated in 2008. The goal of this review was to identify and evaluate the range of instruments used to assess oral mucositis to recommend in evidence-based guidelines the "best" instrument to use in the field of children's and young people's cancer care.

METHODS

Search sources included the Cochrane Library, MEDLINE, EMBASE, and CINAHL. Studies were selected using defined criteria and reviewed by 3 pairs of group members.

RESULTS

Fifty-four individual oral assessment instruments were identified with only 15 reporting evidence of reliability and validity testing. Only 3 articles reported on oral assessment exclusively in our population.

CONCLUSIONS

The guidelines recommend only 1 assessment instrument, the Oral Assessment Guide, or adaptations of this instrument, to be used in clinical practice. Five factors influenced this recommendation: purpose of assessment, population, outcomes assessed, and quality of the instrument and ease of use.

IMPLICATIONS FOR PRACTICE

The Oral Assessment Guide has been consistently judged to be user-friendly and appropriate for everyday clinical practice with both adults and children, as well as a useful research tool.

NO SToPS: Reducing treatment breaks during chemoradiation for head and neck cancer

The addition of chemotherapy to radiation aids in the survival of patients with head and neck cancer but also increases acute toxicity, primarily painful oral mucositis and dermatitis exacerbated by xerostomia. The consequences of these side effects often result in hospitalization and breaks in treatment, which lead to lower locoregional control and survival rates. No strategies reliably prevent radiation-induced mucositis; therefore, emphasis is placed on management to prevent treatment breaks. The NO SToPS approach describes specific multidisciplinary strategies for management of nutrition; oral care; skin care; therapy for swallowing, range of motion, and lymphedema; pain; and social support to assist patients through this difficult therapy.

Laser light may improve the symptoms of oral lesions of cicatricial pemphigoid: a case report

OBJECTIVE

The aim of this work is to report the handling of a patient suffering from cicatricial pemphigoid (CP) treated with laser phototherapy (LPT) and systemic steroids.

BACKGROUND DATA

CP is a group of rare chronic autoimmune blistering diseases that predominately affect the mucous membranes and occasionally the skin. The gingiva is most commonly involved, followed by the palate and the buccal mucosa. High-dosage systemic steroids are widely used for its treatment. LPT has been shown to improve wound healing and relieve pain. Its efficacy depends on the amount of energy delivered to the tissue, exposure time, and delivery method.

MATERIALS AND METHODS

A white 47-y-old man with CP who used systemic steroids for the previous 5 y was examined at our clinic. Extra- and intraoral examination revealed classic signs of the condition. LPT (GaAlAs diode laser, 660 nm wavelength, 30 mW, continuous wave, diameter approximately 3 mm, 60 J/cm(2) per session) was used in association with the steroids. LPT was performed in a punctual contact manner every other day on the oral mucosa. Maintenance of the treatment was carried out weekly because interruption of the LPT resulted in the recurrence of the lesions. At the time that this report was written, the patient had been undergoing twice weekly treatments for 6 months without signs of lesion recurrence.

CONCLUSION

Concomitant use of systemic steroids and LPT showed a positive effect on controlling oral CP lesions and on improving both oral health and the quality of life of the patient.

Citrulline-based assessment score: first choice for measuring and monitoring intestinal failure after high-dose chemotherapy

BACKGROUND

Currently, objective tests are lacking that enable the extent and duration of intestinal mucosal damage induced by myeloablative chemotherapy to be determined. To address this problem, we explored a citrulline-based assessment score as this amino acid is a simple quantitative marker of intestinal failure.

PATIENTS AND METHODS

From March 2004 to June 2007, citrulline concentrations were determined at baseline and at least once weekly after the start of myeloablative chemotherapy until 30 days thereafter among 94 allogeneic or autologous haematopoietic stem-cell transplant recipients. The patients were divided into three groups according to the regimen they received: (i) carmustine, etoposide, cytarabine and melphalan/high-dose melphalan, (ii) cyclophosphamide and total body irradiation +/- antithymocyte globulin and (iii) idarubicin-containing regimens. Intestinal mucosal damage was described either by level of citrulline on each day, on the basis of different thresholds of citrulline indicating the severity of villous atrophy, or by area under the curve using reciprocal value of 10/citrulline.

RESULTS

Regimens that incorporated idarubicin induced the most severe intestinal toxicity. Scores based on the level of citrulline, using severity thresholds, and on the area under the reciprocal curve are able to discriminate between the damage induced by different high-dose chemotherapy regimens.

CONCLUSION

A citrulline-based assessment score appears objective, validated, reproducible, reliable, specific and sensitive making it a suitable first choice for measuring and monitoring intestinal mucositis.

Explorative study on the predictive value of systematic inflammatory and metabolic markers on weight loss in head and neck cancer patients undergoing radiotherapy

PURPOSE

This study aimed to explore the predictive value of systematic inflammatory and metabolic markers in head and neck (H&N) cancer patients during radiotherapy (RT).

METHODS

Twenty-seven patients were evaluated. The protocol included serial blood tests [highly sensitive C-reactive protein (hsCRP), albumin, insulin-like growth factor 1 (IGF-1), IGF binding protein 1 (IGFBP-1) and ghrelin], measurements of body weight and assessment of oral mucositis.

RESULTS

The mean nadir of weight loss was observed at the end of RT. At the time of diagnosis, mean hsCRP was 5.2 ± 1.0 mg/L. HsCRP significantly increased during RT and decreased during the post-RT period. Mean maximum hsCRP was 35.8 ± 8.5 mg/L, with seven patients reaching >40 mg/L. A numerical decrease of albumin (by 18.2%) and only small changes in IGF-1, IGFBP-1 and ghrelin levels were observed. None of the metabolic parameters was significantly associated with weight loss.

CONCLUSIONS

HsCRP increased in response to RT for H&N cancer as a sign of irradiation-induced inflammation. Weight loss was not preceded by changes of the metabolic parameters, indicating that assessment of the blood markers used in this study is of little value. Regular body weight measurement and assessment of oral mucositis are feasible, cheap and important procedures to control the metabolic homeostasis during RT.

Radiation therapy for head and neck cancers

OBJECTIVES

To provide an overview of the state of the art in the management of head and neck cancers with radiation therapy (RT) and review issues concerning dose-fractionation, concurrent systemic treatment as well as acute and chronic toxicity.

DATA SOURCES

Published peer-reviewed research articles, technical documents, and patient management guidelines.

CONCLUSION

Modern RT techniques can use technical advances to precisely target regions involved by the tumor, while sparing normal structures. This has significant implications for treatment decisions and anticipated treatment toxicities. Our understanding of radiation effects on tumor and normal tissues and their optimal care are continuously evolving.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to be aware of the basic principles underlying the technical advances in RT in order to be able to counsel patients during their decision-making and treatment. They also need to stay updated on the pathophysiology and current management of acute and chronic toxicities of radiation treatment in order to provide optimal supportive care.
