Interventions for preventing oral mucositis for patients with cancer receiving treatment

Anti-inflammatory latex proteins of the medicinal plant Calotropis procera: a promising alternative for oral mucositis treatment

OBJECTIVE AND DESIGN

Oral mucositis (OM) is an intense inflammatory reaction progressing to tissue damage and ulceration. The medicinal uses of Calotropis procera are supported by anti-inflammatory capacity. PII-IAA, a highly homogenous cocktail of laticifer proteins (LP) prepared from the latex of C. procera, with recognized pharmacological properties was tested to treat OM.

MATERIALS AND SUBJECTS

Male Golden Sirius hamsters were used in all treatments.

TREATMENT

The latex protein samples were injected i.p. (5 mg/Kg) 24 h before mucositis induction (mechanical trauma) and 24 h later.

METHODS

Histology, cytokine measurements [ELISA], and macroscopic evaluation [scores] were performed.

RESULTS

PII-IAA eliminated OM, accompanied by total disappearance of myeloperoxidase activity and release of IL-1b, as well as reduced TNF-a. Oxidative stress was relieved by PII-IAA treatment, as revealed by MDA and GSH measurements. PII-IAA also reduced the expression of adhesion molecules (ICAM-1) and Iba-1, two important markers of inflammation, indicating modulatory effects. Histological analyses of the cheek epithelium revealed greater deposition of type I collagen fibers in animals given PII-IAA compared with the control group. This performance was only reached when LPPII was treated with iodoacetamide (IAA), an irreversible inhibitor of proteolytic activity of cysteine proteases. The endogenous proteolytic activity of LPPII induced adverse effects in animals. Candidate proteins involved in the phytomodulatory activity are proposed.

CONCLUSIONS

Therapy was successful in treating OM with the laticifer protein fraction, containing peptidases and osmotin, from Calotropis procera. The effective candidate from the latex proteins for therapeutic use is PII-IAA.

Use of a natural multicomponent mouthwash plus oral hygiene vs oral hygiene alone to prevent everolimus-induced stomatitis: the STOP multicenter, randomized trial

BACKGROUND

Stomatitis is highly prevalent in patients with cancer treated with the mammalian target of rapamycin inhibitor everolimus; it usually has an early onset and may compromise treatment dose intensity and patients' quality of life. Within the randomized controlled Stomatitis Prevention trial (STOP, ISRCTN14568888), we investigated the possibility of using a commercial natural multicomponent mouthwash (Orasol Plus®) to prevent the development of stomatitis of any grade in patients with advanced renal cell carcinoma (RCC) treated with everolimus.

METHODS

Overall, 62 patients were randomized to receive either Orasol Plus in addition to oral hygiene or oral hygiene alone (31 patients per treatment arm).

RESULTS

In the whole study population, 28 episodes of stomatitis were observed (41.9%); in only 2 patients, stomatitis occurred more than once (2 episodes). As expected, the episodes of stomatitis occurred early in the course of treatment with everolimus. Treatment with Orasol Plus prevented the onset of everolimus-induced stomatitis: only 8 episodes of stomatitis were observed in the treated group with Orasol Plus in addition to oral hygiene vs 20 episodes in the group treated with oral hygiene only (p = 0021). Also, a reduction in the average duration of mucositis in patients treated with Orasol Plus compared to patients treated with oral hygiene only was observed (8 days vs 11.2 days, p = 0.0416).

CONCLUSION

This study showed that the use of a natural multicomponent mouthwash coupled with regular oral hygiene was able to reduce the severity and duration of everolimus-induced stomatitis in patients with RCC.

Oral cryotherapy for prophylaxis of oral mucositis caused by docetaxel, cisplatin, and fluorouracil chemotherapy for esophageal cancer

BACKGROUND

Chemotherapy, including preoperative chemotherapy, plays an important role in the treatment of esophageal cancer. However, although docetaxel, cisplatin, and fluorouracil (DCF) therapy has a powerful antitumor effect, the associated adverse events make it difficult to maintain the patient's general condition. Oral mucositis is an important adverse effect of chemotherapy, and its severity, frequency, and impact on patient quality of life should not be underestimated. This study evaluated the role of oral cryotherapy for prophylaxis of oral mucositis caused by DCF therapy.

METHODS

We retrospectively examined the incidence and severity of adverse events, including mucositis, in 72 patients with esophageal cancer treated with DCF. Fifty-eight patients received cryotherapy during docetaxel administration and 14 received no cryotherapy.

RESULTS

The incidence of mucositis of all grades and grade 3 was significantly lower in the cryotherapy group compared with the no-cryotherapy group (24.1% vs. 71.4%, P < 0.001 and 0% vs. 28.6%, P = 0.001, respectively). The incidence of anorexia of all grades and grade 3 was also significantly lower in the cryotherapy group (22.4% vs. 57.1%, P = 0.037 and 0% vs. 28.6%, P = 0.010, respectively).

CONCLUSION

Adjunctive oral cryotherapy is effective for the prophylaxis and relief of oral mucositis and anorexia caused by chemotherapy.

Double-blind, randomized pilot study of bioadhesive chlorhexidine gel in the prevention and treatment of mucositis induced by chemoradiotherapy of head and neck cancer

Background

To evaluate, in an initial way, the effectiveness of bioadhesive chlorhexidine gel 0.2% versus placebo as a preventive and therapeutic intervention of oral mucositis induced by radiation therapy and chemotherapy in patients diagnosed with head and neck cancer treated with chemoradiotherapy.

Material and Methods

In this pilot study, 7 patients (range of age: 18- 65), having histological documented diagnosis of squamous carcinoma on the head and neck region in stage III and IV, and receiving combined radiation treatment and chemotherapy (cisplatin 100 mg/m2 IV on days 1, 22, and 43 of irradiation) were studied. Simultaneously, a topical application was performed with bioadhesive chlorhexidine gel 0.2% in the study group, and the placebo gel for the control group in 5 applications per day, from the time of initiation of cancer treatment to 2 weeks after completion of chemo-radiotherapy treatment (11 weeks of follow-up). The gradation of mucositis, pain, analgesic consumption, infectious complications, and treatment tolerance was measured.

Results

After 7 patients completed the protocol, any differences were observed between groups in an interval analysis. Mucositis, pain, and tolerance was similar in both groups.

Conclusions

Our results must be interpreted with caution due to the reduced sample size, but the use of bioadhesive chlorhexidine gel 0.2% didn’t contribute clinical improvement to the oral mucositis induced by radiation therapy and chemotherapy.

Key words: Chlorhexidine, mucositis, head and neck cancer.

Double-blind, placebo-controlled, randomized phase II study of TJ-14 (hangeshashinto) for gastric cancer chemotherapy-induced oral mucositis

BACKGROUND

Hangeshashinto (TJ-14, a Kampo medicine), which reduces the level of prostaglandin E2 and affects the cyclooxygenase activity, alleviates chemotherapy-induced oral mucositis (COM). We conducted a randomized comparative trial to investigate whether TJ-14 prevents and controls COM in patients with gastric cancer.

METHODS

We randomly assigned patients with gastric cancer who developed moderate-to-severe oral mucositis (CTCAE v4.0 grade ≧1) during any cycle of chemotherapy to receive either TJ-14 or a placebo as a double-blind trial. The patients received a placebo or TJ-14 for 2-6 weeks according to the chemotherapy regimen from the beginning of the next course of chemotherapy. The primary end point was the incidence of grade ≧2 oral mucositis in the protocol treatment course, and the secondary end points were the time to disappearance of oral mucositis and the incidence of adverse events.

RESULTS

Following the key opening of the blinding protocol, we analyzed 91 eligible patients (TJ-14: 45, placebo: 46) using a "per protocol set" analysis. The incidence of ≧grade 2 COM was 40.0 % in the TJ-14 group and 41.3 % in the placebo group (p = 0.588). The median duration of ≧grade 2 COM was 14 days in the TJ-14 group and 16 days in the placebo group (p = 0.894). Meanwhile, the median duration of any grade of COM was 9 days in the TJ-14 group and 17 days in the placebo group among the patients who developed grade 1 symptoms during the screening cycle [hazard ratio 0.60; 95 % CI (0.23-1.59), p = 0.290].

CONCLUSIONS

Although TJ-14 treatment did not reduce the incidence of ≥2 COM in the patients who developed mucositis during chemotherapy for gastric cancer, a trend was observed in which TJ-14 reduced the risk of COM in the patients who developed grade 1 COM during the screening cycle. Further, phase III studies with a larger sample size are needed to clarify the protective effects of TJ-14 for COM.

A survey of chinese medicinal herbal treatment for chemotherapy-induced oral mucositis

Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM) offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

Strategies for assessing and managing the adverse events of sorafenib and other targeted therapies in the treatment of renal cell and hepatocellular carcinoma: recommendations from a European nursing task group

PURPOSE

As a group of European nurses familiar with treating patients with renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC) using targeted/chemo- therapies, we aimed to review strategies for managing adverse events (AEs) associated with one targeted therapy, sorafenib.

METHOD

Focusing on the AEs we considered the most difficult to manage (hand-foot skin reaction [HFSR], diarrhoea, fatigue and mucositis/stomatitis), we reviewed the literature to identify strategies relevant to sorafenib. Given the paucity of published work, this included strategies concerning targeted agents in general. This information was supplemented by considering the wider literature relating to management of these AEs in other tumour types and similar toxicities experienced during conventional anti-cancer therapy. Together with our own experience, this information was used to compile an AE management guide to assist nurses caring for patients receiving sorafenib.

RESULTS

Our collated experience suggests the most commonly reported AEs with sorafenib and other targeted agents are HFSR, diarrhoea, fatigue, rash and mucositis/stomatitis; these generally have an acute (appearing at ∼0-1 months) or delayed onset (appearing at ∼3 months). Most management strategies in the literature were experience-based rather than arising from controlled studies. However, strategies based on controlled studies are available for HFSR and mucositis/stomatitis.

CONCLUSIONS

Evidence, especially from controlled studies, is sparse concerning management of AEs associated with sorafenib and other targeted agents in RCC/HCC. However, recommendations can be made based on the literature and clinical experience that encompasses targeted and conventional therapies, particularly in the case of non-specific toxicities e.g. diarrhoea and fatigue.

Interventions for preventing oral mucositis for patients with cancer receiving treatment

BACKGROUND

Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers).

OBJECTIVES

To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment.

SEARCH STRATEGY

Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 16 February 2011), CENTRAL (The Cochrane Library 2011, Issue 1), MEDLINE via OVID (1950 to 16 February 2011), EMBASE via OVID (1980 to 16 February 2011), CINAHL via EBSCO (1980 to 16 February 2011), CANCERLIT via PubMed (1950 to 16 February 2011), OpenSIGLE (1980 to 2005) and LILACS via the Virtual Health Library (1980 to 16 February 2011) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information.

SELECTION CRITERIA

Randomised controlled trials of interventions to prevent oral mucositis in patients receiving treatment for cancer.

DATA COLLECTION AND ANALYSIS

Information regarding methods, participants, interventions, outcome measures, results and risk of bias were independently extracted, in duplicate, by two review authors. Authors were contacted for further details where these were unclear. The Cochrane Collaboration statistical guidelines were followed and risk ratios calculated using random-effects models.

MAIN RESULTS

A total of 131 studies with 10,514 randomised participants are now included. Overall only 8% of these studies were assessed as being at low risk of bias. Ten interventions, where there was more than one trial in the meta-analysis, showed some statistically significant evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis, compared to either a placebo or no treatment. These ten interventions were: aloe vera, amifostine, cryotherapy, granulocyte-colony stimulating factor (G-CSF), intravenous glutamine, honey, keratinocyte growth factor, laser, polymixin/tobramycin/amphotericin (PTA) antibiotic pastille/paste and sucralfate.

AUTHORS' CONCLUSIONS

Ten interventions were found to have some benefit with regard to preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for further well designed, and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

Molecular methodology to assess the impact of cancer chemotherapy on the oral bacterial flora: a pilot study

OBJECTIVE

This pilot study determined the profile of the oral bacterial flora in an outpatient cancer population before and after chemotherapy using molecular techniques.

STUDY DESIGN

We recruited 9 newly diagnosed breast cancer patients scheduled for induction chemotherapy. All were seen immediately before chemotherapy, and 7 to 14 days later. At both visits, we performed oral evaluations and obtained mucositis grading (with the World Health Organization [WHO] scale), absolute neutrophil counts (ANC), and bacterial samples from the buccal mucosa. Bacterial DNA was isolated, and 16S ribosomal RNA gene clonal libraries were constructed. Sequences of genes in the library were used to determine species identity by comparison to known sequences.

RESULTS

After chemotherapy, WHO scores of 0 and 1 were in 3 and 6 patients, respectively, and mean ANC (+/-SD) dropped from 3326 +/- 463 to 1091 +/- 1082 cells/mm(3). From pre- and post-chemotherapy samples, 41 species were detected, with a predominance of Gemella haemolysans and Streptococcus mitis. More than 85% of species have not been previously identified in chemotherapy patients. Seven species appeared exclusively before chemotherapy and 25 after chemotherapy. After chemotherapy, the number of species per patient increased by a mean of 2.6 (SD = 4.7, P = .052).

CONCLUSION

We identified species not previously identified in chemotherapy patients. Our results suggest a shift to a more complex oral bacterial profile in patients undergoing cancer chemotherapy.

New pathways for alimentary mucositis

Alimentary mucositis is a major dose-limiting toxicity associated with anticancer treatment. It is responsible for reducing patient quality of life and represents a significant economic burden in oncology. The pathobiology of alimentary mucositis is extremely complex, and an increased understanding of mechanisms and pathway interactions is required to rationally design improved therapies. This review describes the latest advances in defining mechanisms of alimentary mucositis pathobiology in the context of pathway activation. It focuses particularly on the recent genome-wide analyses of regimen-related mucosal injury and the identification of specific regulatory pathways implicated in mucositis development. This review also discusses the currently known alimentary mucositis risk factors and the development of novel treatments. Suggestions for future research directions have been raised.

Psychosocial and economic impact of cancer

This article explores the psychosocial and economic implications of cancer and their relevance to the clinician. After a general overview of the topic, the authors focus on aspects of particular importance to the dental professional, including the psychosocial and economic implications of the oral complications of cancer and its therapy, head and neck cancers, and special issues among children with cancer and cancer survivors.

Evaluation of the feasibility and acceptability of an oral care diary by patients during chemotherapy

BACKGROUND

A significant proportion of patients undergoing chemotherapy for many cancer types may experience oral problems, such as mucositis and any deterioration in the health of the oral cavity can have a significant effect on a person's well-being. Trends towards shorter hospital stays and the increase in out-patient chemotherapy mean that patients are required to adopt increasingly participatory roles in their self-care and are subsequently coping with mouth problems while they are at home without the direct support of oncology health professionals.

OBJECTIVES

This study aimed to evaluate the acceptability and feasibility of an oral care diary by patients receiving chemotherapy.

DESIGN

An oral care diary was developed to incorporate oral assessment using the Oral Assessment Guide (Eilier, J., Berger, A., Peterson, M., 1988. Development, testing and application of the oral assessment guide. Oncology Nurse Forum 15, 325-330) and guidance about oral self-care. This exploratory study utilised purpose designed pre- and post-study questionnaires and semi-structured interviews to evaluate patients' perceptions and experiences of the oral care diary.

SETTING

The study took place in 2-day chemotherapy units in Scotland: 1 in a cancer centre and 1 in a district general hospital.

PARTICIPANTS

A consecutive sample of patients (n=45) receiving out-patient chemotherapy for a range of cancer diagnoses participated in the study over 2 cycles of chemotherapy.

METHODS

Following recruitment, patients were instructed in the use of the oral care diary to assess their mouth daily while at home on a daily basis. Patients were asked to complete 2 structured purpose designed questionnaires-the first prior to starting diary completion and the second following their participation in the study. Nine patients participated in semi-structured interviews to explore their actual experiences of using the oral care diary in more depth.

RESULTS

The participants found the oral care diary acceptable and feasible. Awareness of oral symptoms and related mouth self-care post-chemotherapy improved.

CONCLUSIONS

The oral care diary is an acceptable and feasible method of enhancing oral self-care during a course of chemotherapy. Further study is required to evaluate its impact on clinical outcomes.

Oral mucositis, dysfunction, and distress in patients undergoing cancer therapy

AIMS AND OBJECTIVES

This study investigated the patients' self-reported oral dysfunction in relation to oral mucositis and examined the extent to which oral dysfunction and distress correlated with oral mucositis.

BACKGROUND

Oral mucositis is the most symptomatic problem of patients in cancer therapy. However, the levels of oral functional impairment and distress in response to oral mucositis are not thoroughly assessed and researched.

DESIGN AND METHOD

This study employed a descriptive cross-sectional design. Eighty-eight subjects presenting with WHO grade > or =2 oral mucositis during 7-14 days after the initiation of chemotherapy and the last week of head and neck irradiation were enrolled in the study. Subjects were asked to indicate their intensity and distress of oral mucositis and associated oral dysfunction using 1-4 and 0-4 point rating scales, respectively.

RESULTS

Dry mouth and distorted taste were reported by 63 (72%) and 55 (63%) subjects separately. Fifty (57%) and 35 (40%) subjects reported having weight loss and dysphagia, respectively. The mean intensity and the distress score of oral mucositis and oral dysfunction reported by the subjects ranged from 1.96 to 2.51 and 1.58 to 2.09, respectively. The intensity of oral mucositis was significantly correlated with the intensity (r = 0.4-0.6) and the distress scores (r = 0.4-0.6) of oral dysfunction.

CONCLUSION

The findings have demonstrated that the intensity and the distress of oral dysfunction in patients with cancer therapy induced oral mucositis were moderately high from the patients' point of view. The data also supported the correlations between the intensity and the distress of oral mucositis and oral dysfunction.

RELEVANCE TO CLINICAL PRACTICE

Patients treated with chemotherapy and radiotherapy for cancer most often suffer from a multitude of intense and distressing oral dysfunctions in conjunction with oral mucositis. Increased attention and treatment of the oral dysfunction noted are essential for the early identification and relief of distress.

Nursing Interventions and Supportive Care for the Prevention and Treatment of Oral Mucositis Associated with Cancer Treatment

PURPOSE/OBJECTIVES

To review novel approaches to assessing and managing patients with cancer who are at risk for oral mucositis.

DATA SOURCES

Published research and review articles, books, conference presentations, and abstracts.

DATA SYNTHESIS

Oral mucositis is a major source of clinical morbidity among patients with cancer undergoing treatment, yet definitive management strategies continue to elude practitioners. A growing body of evidence suggests that a multifaceted, innovative, targeted approach to oral care provides an important foundation with which to reduce treatment-related morbidity.

CONCLUSIONS

Ongoing assessment and monitoring are critical to the effective management of oral mucositis. Targeted interventions that incorporate the basic principles of wound care with current knowledge about the temporal aspects of clinical manifestations, evidence-based standardized approaches to assessment, and utilization of novel therapeutics provide an important means by which to improve patient outcomes.

IMPLICATIONS FOR NURSING

Oral care protocols are essential components of oral mucositis management. Incorporating current knowledge of pathophysiology with a targeted, standardized approach may help to reduce overall morbidity and improve quality of life.

Interventions for preventing oral candidiasis for patients with cancer receiving treatment

BACKGROUND

Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent and treat them. One of these side effects is oral candidiasis.

OBJECTIVES

To assess the effectiveness of interventions (which may include placebo or no treatment) for the prevention of oral candidiasis for patients with cancer receiving chemotherapy or radiotherapy or both.

SEARCH STRATEGY

Computerised searches of Cochrane Oral Health Group and PAPAS Trials Registers, CENTRAL, MEDLINE, EMBASE, CINAHL, CANCERLIT, SIGLE and LILACS were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. Date of the most recent searches: June 2006: CENTRAL (The Cochrane Library 2006, Issue 2).

SELECTION CRITERIA

Trials were selected if they met the following criteria: design - random allocation of participants; participants - anyone receiving chemotherapy or radiotherapy treatment for cancer; interventions - agents prescribed to prevent oral candidiasis; primary outcome - prevention of oral candidiasis.

DATA COLLECTION AND ANALYSIS

Data were recorded on the following secondary outcomes if present: relief of pain, amount of analgesia, relief of dysphagia, incidence of systemic infection, duration of stay in hospital (days), cost of oral care, patient quality of life, death, use of empirical antifungal treatment, toxicity and compliance. Information regarding methods, participants, interventions, outcome measures and results were independently extracted, in duplicate, by two review authors. The Cochrane Oral Health Group statistical guidelines were followed and risk ratios (RR) calculated using random-effects models. Potential sources of heterogeneity were examined in random-effects metaregression analyses.

MAIN RESULTS

Twenty-eight trials involving 4226 patients satisfied the inclusion criteria. Drugs absorbed and partially absorbed from the gastrointestinal (GI) tract were found to prevent oral candidiasis when compared to a placebo, or a no treatment control group, with RR for absorbed drugs = 0.47 (95% confidence interval (CI) 0.29 to 0.78). For absorbed drugs in populations with an incidence of 20% (mid range of results in control groups), this implies a NNT of 9 (95% CI 7 to 13) patients need to be treated to avoid one patient getting oral candidiasis. There was no significant benefit shown for drugs not absorbed from the GI tract.

AUTHORS' CONCLUSIONS

There is strong evidence, from randomised controlled trials, that drugs absorbed or partially absorbed from the GI tract prevent oral candidiasis in patients receiving treatment for cancer. There is also evidence that these drugs are significantly better at preventing oral candidiasis than drugs not absorbed from the GI.

Putting Evidence Into Practice: Prevention of Infection

The prevention of infection is an important outcome to measure in patients with cancer because infectious complications are a significant cause of morbidity and mortality. Nurses play a vital role in the prevention of infection in patients with cancer through nursing practice, research, and patient education. However, many common nursing interventions to prevent infection are based on tradition or expert opinion and have not been subjected to scientific examination. The 2005 Oncology Nursing Society Prevention of Infection Outcomes Intervention Project Team reviewed, critiqued, and summarized the research evidence for nursing interventions to prevent infections in patients with cancer. Pharmacologic and nonpharmacologic interventions were included because many advanced practice nurses prescribe medications. This article is an evidence-based review of nursing interventions to prevent infection in patients with cancer.

The effectiveness of commonly used mouthwashes for the prevention of chemotherapy-induced oral mucositis: a systematic review

Daily chlorhexidine mouthwash is often recommended for preventing chemotherapy-induced oral mucositis. Povidone-iodine, NaCl 0.9%, water salt soda solution and chamomile mouthwash are also recommended. However, the effectiveness of these mouthwashes is unclear. Therefore, we performed a systematic review to assess the effectiveness of mouthwashes in preventing and ameliorating chemotherapy-induced oral mucositis. Based on study quality, three out of five randomized controlled trials were included in a meta-analysis. The results failed to detect any beneficial effects of chlorhexidine as compared with sterile water, or NaCl 0.9%. Patients complained about negative side-effects of chlorhexidine, including teeth discoloration and alteration of taste in two of the five studies on chlorhexidine. The severity of oral mucositis was shown to be reduced by 30% using a povidone-iodine mouthwash as compared with sterile water in a single randomized controlled trial. These results do not support the use of chlorhexidine mouthwash to prevent oral mucositis.

Risk factors for oral mucositis in paediatric oncology patients receiving alkylant chemotherapy

BACKGROUND

We describe the risk indicators for oral mucositis (OM) in paediatric oncology patients hospitalised in the Institut Gustave Roussy (Villejuif-Paris) and treated with alkylant chemotherapy with autologous peripheral blood progenitor cells.

METHODS

The sample was selected using PIGAS software. Three groups of subjects received different chemotherapy regimens: A. Melphalan, B. Busulfan and C. other alkylant protocols. The degree of mucositis was recorded by CTC version 2.0 (Common Toxicity Criteria). Descriptive statistics were performed. The association between mucositis and risk indicator variables was tested using a chi2 test. The association between case status and covariates was tested using unconditional logistic regression analysis.

RESULTS

Of the 337 children enrolled, 241 showed mucositis (group 1) and 96 did not show mucositis (group 2) during alkylant chemotherapy. There was a higher prevalence of male patients in both groups. The three different chemotherapy regimen groups are correlated with the appearance of oral mucositis (chi2 = 22.42, p < 0.01). Weight loss was higher in group 1 (chi2 = 6.31, p = 0.01). The duration of aplasia was lower in the Busulfan protocol (7.5 days) than in the Melphalan group (9.3 days) or the other regimens (8.6 days). The use of Bufulfan was directly associated with case status (presence of oral mucositis): odds ratio [OR] = 2.1 and confidence interval [95%CI] = 1.3-3.0. Also, occurrences of germinal tumours and secondary bacterial infections were directly linked with case status: [OR] = 1.4 and 1.8, confidence interval [95%CI] = 1.2 - 1.7 and 1.1 - 2.5, respectively.

CONCLUSION

The presence of OM was associated with the three different chemotherapy regimens considered; in particularly patients treated with Busulfan had the highest prevalence.

The role of basic oral care and good clinical practice principles in the management of oral mucositis

BACKGROUND

The Basic Oral Care Group is one of eight subcommittees functioning within the Mucositis Study Group Guidelines Panel of the Multinational Association of Supportive Care in Cancer and International Society for Oral Oncology (MASCC/ISOO). The Basic Oral Care Group, comprised of the four authors of this paper, represented the disciplines of nursing (DBM, JJ), dentistry (MEPC), and pediatric dentistry (PW). This group reviewed research and clinical literature to update the original 2004 Mucositis Management Guidelines in the areas of basic oral care, bland rinses, protocols and education, and good clinical practices such as pain management, oral assessment, oral care, and dental care.

MATERIALS AND METHODS

Over 100 articles published between 2000 and 2005 were identified, and 32 of these were useful for the analysis. Each article was rated by at least two authors using a structured rating form and systematic determination of levels of evidence, based on the American Society of Clinical Oncology criteria. Discussion at the 2005 MASCC/ISOO Geneva pre-conference meeting of the Guidelines Panel resulted in the development of consensus on the interpretation of the literature.

RESULTS

Based on the literature and on Panel discussions, a revision of the original guidelines for protocols and education was produced by the group, and they developed a set of recommendations related to good clinical practices.

CONCLUSIONS

Although research remains scanty for components of basic oral care, bland rinses, protocols, and education, the original 2004 guidelines with the help of newer literature from 2000 to 2005 and expert consensus among the Guidelines Panel enabled the development of useful clinical practice guidelines for managing oral mucositis in patients receiving cancer treatment with radiation and/or chemotherapy.

The molecular immunology of mucositis: implications for evidence-based research in alternative and complementary palliative treatments

The terms 'mucositis' and 'stomatitis' are often used interchangeably. Mucositis, however, pertains to pharyngeal-esophago-gastrointestinal inflammation that manifests as red, burn-like sores or ulcerations throughout the mouth. Stomatitis is an inflammation of the oral tissues proper, which can present with or without sores, and is made worse by poor dental hygiene. Mucositis is observed in a variety of immunosuppressed patients, but is most often consequential to cancer therapy. It appears as early as the third day of intervention, and is usually established by Day 7 of treatment. Mucositis increases mortality and morbidity and contributes to rising health care costs. The precise immune components involved in the etiology of mucositis are unclear, but evidence-based research (EBR) data has shown that applications of granulocyte-macrophage-colony stimulating factor prevent the onset or the exacerbation of oropharyngeal mucositis. The molecular implications of this observation are discussed from the perspective of future developments of complementary and alternative treatments for this condition. It must be emphasized that this article is meant to be neither a review on mucositis and the various treatments for it, nor a discussion paper on its underlying molecular immunology. It is a statement of the implications of EBR for CAM-based interventions for mucositis. It explores and discusses the specific domain of molecular immunology in the context of mucositis and its direct implications for EBR research in CAM-based treatments for mucositis.

A guide to managing the pain of treatment-related oral mucositis

Oral mucositis is a common complication of chemotherapy and/or radiotherapy and can be a significant problem for patients undergoing cancer treatment or bone marrow transplantation. Frequently, there is a major adverse impact on quality of life, particularly with pain and interference with oral function. In patients who are immunocompromised or debilitated, this complication can become life threatening. Currently, there is no single intervention that completely prevents or treats oral mucositis. The object of this article is to provide an overview for the nurse of the evidence for several options that may be of value in managing the pain which is often associated with this condition.

Randomized controlled trial of pilocarpine hydrochloride for the moderation of oral mucositis during autologous blood stem cell transplantation

Pilocarpine hydrochloride has been reported to increase salivation and decrease oral mucositis in patients receiving head and neck radiotherapy, but there is only one report of its use in a cancer chemotherapy patient population. This prospective, double-blinded, randomized, placebo-controlled trial was undertaken to determine the efficacy of pilocarpine for the moderation of oral mucositis during autologous blood stem cell transplantation. Subjects were randomized to receive a 5 mg tablet of pilocarpine, or a placebo, during and following chemotherapy. Subjects were seen every other day and evaluated for gingival, oral, and oropharyngeal mucositis; nutrition; oral hygiene; eating; speaking; sleeping; pain at rest and/or with swallowing; and mouth dryness. We recorded the mean and highest scores and duration of problems, along with white blood cell counts and differentials, and the use of systemic narcotics for oral mucosal pain. We enrolled and randomized 36 subjects, and there were no statistically or clinically significant differences for the primary outcome of severity of mucositis and no clinically significant differences in any of the other outcome measures. Pilocarpine has no benefit for the moderation of the incidence, severity, or duration of mucositis in patients receiving autologous blood stem cell transplantation.
