Oral cryotherapy reduces mucositis and improves nutrition – a randomised controlled trial

AIM AND OBJECTIVE To investigate if oral cryotherapy during myeloablative therapy may influence frequency and severity of mucositis, nutritional status and infection rate after bone marrow transplantation. BACKGROUND Patients treated with intensive myeloablative treatment before bone marrow transplantation are all at risk to develop mucositis. Oral mucositis causes severe pain and oral dysfunction, which can contribute to local and systemic infections and bleeding; it may even interrupt cancer therapy. Oral mucositis also decreases the oral food intake, which increases the risk for malnutrition and infection. Reduced food intake, loss of fat and muscles, alterations in energy and substrate metabolism leads to malnutrition. DESIGN A randomised controlled trial with a random assignment to experimental or control group. METHOD A stratified randomisation was used with regard to the type of transplantation. Mucositis was measured on WHO mucositis scale. Number of days of total parenteral nutrition, infection rate, weight, albumin levels and days at hospital was compared. RESULTS There were significantly fewer patients in the experimental group with mucositis grade 3-4 than in the control group and significantly lower number of days in the hospital (allogeneic patients). Less total parenteral nutrition was needed in the experimental group in both settings, and the S-albumin level was significantly better preserved. No significant difference could be found with regard to infection rate. CONCLUSION Oral cryotherapy reduced mucositis, number of hospital days, the need for total parenteral nutrition and resulted in a better nutritional status. RELEVANCE TO CLINICAL PRACTICE Nurses caring for patients treated with myeloablative therapy should place high priority to prevent oral mucositis and hereby reduce its side effects.

Five-year follow-up of survival and relapse in patients who received cryotherapy during high-dose chemotherapy for stem cell transplantation shows no safety concerns

We have previously published a randomised controlled study of the efficacy of cryotherapy in preventing acute oral mucositis after high-dose chemotherapy for stem cell transplantation. The present study is a 5-year follow-up safety study of survival in these patients. In the previously published study oral cryotherapy (cooling of the oral cavity) during high-dose chemotherapy significantly reduced mucositis grade and opiate use in the treated group. All patients were followed up for at least 5 years with regard to relapse and death rates. Baseline data, transplant complications and mucositis data were compared. Significantly more patients (25/39) who received oral cryotherapy were alive after 5 years compared to 15/39 in the control group (P= 0.025). Relapse rates were similar. The only baseline difference was a lower proportion of patients in complete remission at transplantation in the control group (6 vs. 13, P= 0.047). This 5-year follow-up study gave no support for safety concerns with cryotherapy.

Caphosol® mouthwash gives no additional protection against oral mucositis compared to cryotherapy alone in stem cell transplantation. A pilot study

PURPOSE To investigate if adding Caphosol(®), a mouthwash solution, to oral cryotherapy (OC) further protects against oral mucositis (OM), a toxic painful complication to high dose chemotherapy. METHOD The study was a randomised, controlled, study design. Patients ≥16 years scheduled for allogeneic stem cell transplantation were included consecutively and randomised to experimental group receiving OC combined with Caphosol(®) (n = 20) or control group receiving OC only (n = 20). OC was given from start to end of HDCT. Caphosol(®), from day 0 to day 21. RESULT There were no significant differences regarding age or gender between the groups. Mucositis was assessed with the World Health Organisation (WHO) grading scale. Pain was assessed with a 10 cm visual analogue scale (VAS) from 0 = no pain to 10 = worst imaginable pain. Start and duration of therapy with pain relieving drugs, serum C-reactive protein values, and number of days of hospitalisation were collected from the medical records. Data on OM, oral pain, use of i.v. opioids and total parenteral nutrition were collected during 22 days. There was no significant difference between the groups on OM, oral pain, use of i.v. opioids or TPN between the groups. CONCLUSION The study showed no additional effect of combining Caphosol(®) with OC.

Addition of Aprepitant (Emend®) to Standard Antiemetic Regimen Continued for 7 Days after Chemotherapy for Stem Cell Transplantation Provides Significant Reduction of Vomiting

Chemotherapy-induced nausea/vomiting (CINV) is a major problem for patients treated with high-dose chemotherapy (HDCT) conditioning before stem cell transplantation (SCT), both during chemotherapy and afterwards (delayed nausea/vomiting). The standard of care (5-HT3 antagonist and dexamethasone) appears to be ineffective against delayed nausea and vomiting. The objective of this study was to compare standard antiemetic treatment with standard treatment plus prolonged treatment with aprepitant (Emend®) until 7 days after the end of chemotherapy in patients treated with HDCT before autologous SCT. Ninety-six patients were randomized to the experiment (EXP) group receiving Emend in addition to standard antiemetics or to the control (CTR) group receiving placebo. Emend or placebo treatment started 1 h before the first HDCT dose for SCT and ended 7 days after HDCT. Thirty-eight patients in the EXP group experienced complete response (no vomiting) compared to 16 patients in the CTR group. There was a significant difference between the EXP (0.63 ± 2.71) and the CTR (3.72 ± 4.91) group during 10 days after the end of HDCT (p = 0.001) with regard to the number of vomiting episodes. No difference with regard to days of nausea or in the use of antiemetic rescue was noted between the groups. We conclude that standard antiemetic treatment can be improved by addition of aprepitant continued for 7 days after the end of chemotherapy.

Efficacy of a novel intraoral cooling device

Background: Oral mucositis (OM) is a common debiliating adverse effect following high dose chemotherapy prior to bone marrow transplantation. OM often interferes with food intake and lead to malnutrition, weight loss and impaired quality of life. These adverse effects may require intravenous morphine for pain alleviation, Although uncomfortable to the patient, oral cryotherapy with ice chips has been shown to reduce the grade and extent of OM. Purpose: The purpose of the present study is to evaluate whether an intraoral cooling device has the same effectiveness as ice chips when it comes to cooling the oral mucosa. Method: Five healthy volunteers (mean age 36.2 years) chewed ice under surveillance for 30 minutes. Before the start of and immediately after the termination of the ice chewing, the intraoral mucosal temperature was measured using a modified thermometer. The same protocol was used to asses the cooling efficacy obtained by the newly developed intraoral device. Results: No statistical significant differences in cooling of teh oral mucosa (p=0.12) were obtained. The mean surface temperature following cooling was 25.7 degrees Celcius with ice chips and 24.7 degrees Celcius with the cooling device. Conclucion: The cooling device is as effective as ice chips in terms of cooling the oral mucosa. The next step in this research is to use the cooling devise to establish the highest surface temperature of the oral mucosa, during infusion of chemotherapy, that will still result in prevention of oral mucositis.Introduction Lifestyle interventions might be useful in the management of adverse effects of androgen deprivation therapy (ADT) in men with prostate cancer. Objectives To examine the effects of dietary and exercise interventions on quality of life (QoL), metabolic risk factors and androgen deficiency symptoms in men with prostate cancer undergoing ADT. Methods CINAHL, Cochrane library, Medline and PsychINFO were searched to identify randomised controlled trials published from January, 2004 to October, 2014. Data extraction and methodological quality assessment was independently conducted by two reviewers. Meta-analysis was conducted using RevMan® 5.3.5. Results Of 2183 articles retrieved, 11 studies met the inclusion criteria and had low risk of bias.Nine studies evaluated exercise (resistance and/or aerobic and/or counselling) and three evaluated dietary supplementation. Median sample size =79 (33–121) and median intervention duration was 12 weeks (12–24). Exercise improved QoL measures (SMD 0.26, 95%CI −0.01 to 0.53) but not body composition, metabolic risk or vasomotor symptoms. Qualitative analysis indicated soy (or isoflavone) supplementation did not improve vasomotor symptoms; however, may improve QoL. Conclusions Few studies have evaluated the efficacy of lifestyle interventions in the management of adverse effects of ADT. We found inconclusive results for exercise in improving QoL and negative results for other outcomes. For soy-based products, we found negative results for modifying vasomotor symptoms and inconclusive results for improving QoL. Future work should investigate the best mode of exercise for improving QoL and other interventions such as dietary counselling should be investigated for their potential to modify these outcomes.
