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

Effectiveness of Oral Cryotherapy for Oral Mucositis on Cancer Patient Undergoing Cancer Therapy: A Systematic Review

BACKGROUND: Oral mucositis is one of the complications in patients undergoing cancer therapy. Oral cryotherapy (OC) is an intervention to reduce the severity of oral mucositis. AIM: To identify, analyze, and evaluate articles regarding the effectiveness of cryotherapy for oral mucositis in cancer patients undergoing cancer therapy. METHODS: We performed searching on seven databases (PubMed, CENTRAL, Wiley, CANCERLIT, Science Direct, EBSCO, and SpringerLink). The investigation focused on English-language articles, intervention, or observational study reporting on the effectiveness of OC against oral mucositis in patients undergoing chemotherapy, and published between October 2015 and October 2020. RESULTS: Eleven articles met the eligibility criteria for inclusion consisting of 5 RCTs, 3 Quasi-Experiment studies, 2 Cohort studies, and one pre-experimental study. The majority of the studies show that OC is an effective intervention to reduce the degree and severity of oral mucositis in patients undergoing cancer therapy (Hematopoietic Stem Cell Transplantation and chemotherapy). CONCLUSION: OC is practical, low-cost, and relatively safe and can be an alternative therapy in reducing oral mucositis as a side effect of cancer therapy.

Effects of an elemental diet to reduce adverse events in patients with esophageal cancer receiving docetaxel/cisplatin/5-fluorouracil: a phase III randomized controlled trial-EPOC 2 (JFMC49-1601-C5)

Background

Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy.

Patients and methods

In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance.

Results

Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046).

Conclusions

The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy.

•

Patients receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy commonly develop oral mucositis (OM).

•

An elemental diet (ED) was able to prevent OM in patients with esophageal cancer receiving DCF.

•

Grade ≥2 OM was observed in 15% of patients receiving the ED versus 34% of those not receiving the ED (P = 0.0141).

•

Body weight was maintained in the ED group, and hematologic toxicities were lower, compared with the non-ED group.

•

The DCF completion rate significantly correlated with ED compliance (P = 0.0046).

Eficacy of Cryotherapy in the Prevention of Oral Mucosistis in Adult Patients with Chemotherapy

Oral mucositis (OM) is a common side effect of cancer therapies. It causes ulcerative, painful lesions in the oral cavity that can provoke malnutrition, increased risk of infection, longer hospital stays, and seriously affect the quality of life. Cooling the mucosa with oral cryotherapy (OC) during and/or after chemotherapy is the most accessible and tolerable intervention available. The aim of this study is to define the efficacy of OC for preventing OM induced by chemotherapy/radiotherapy in adult patients with cancer. Secondary endpoints include associated problems as pain. A systematic search was performed using the Pubmed, WOS (Web of Science), Cochrane Library, CINAHL, and BVS databases for articles published up to 2010. After inclusion and exclusion criteria were applied, a total of eight articles were analyzed in this review. In seven of the eight articles, the incidence of OM of all grades was significantly lower in the OC group compared with the no-OC group. Use of opioids and level of pain were also significantly reduced. OC is an effective intervention to reduce the incidence of OM induced by chemotherapy as well as the associated severity and pain. Based on these results, OC with only water or with chamomile, associated or not with other mouthwash therapies, is an effective intervention to reduce the incidence of OM induced by chemotherapy as well as the associated severity and pain.

Effect of cryotherapy in preventing mucositis associated with the use of 5-fluorouracil

Objective:

to evaluate the effect of oral cryotherapy compared to physiological serum on the development of oral mucositis in outpatient cancer patients using the 5-fluorouracil antineoplastic agent.

Method:

this is a controlled, randomized, double-blind, and multi-center clinical trial, conducted with 60 patients undergoing chemotherapy. The experimental group (n=30) used oral cryotherapy during the infusion of the 5-FU antineoplastic agent, while the control group (n=30) performed mouthwash with physiological serum at their homes. The oral cavity of the participants was assessed at three times: before randomization, and on the 7^th and 14^th days after using 5-FU. For data analysis, descriptive analyses and the ANOVA, paired t, and McNemar tests were used.

Results:

there was no statistically significant difference between the experimental and control groups in the assessments regarding the grade of mucositis. However, cryotherapy presented the chance to reduce the presence of intragroup mucositis, between the first and second assessments (p=0.000126).

Conclusion:

cryotherapy did not obtain statistical significance in relation to oral hygiene with serum, but it proved to be effective intragroup. Record number: RBR-4k7zh3

Potential Therapeutic Effects of Gut Hormones, Ghrelin and Obestatin in Oral Mucositis

Chemotherapy and/or head and neck radiotherapy are frequently associated with oral mucositis. Oral pain, odynophagia and dysphagia, opioid use, weight loss, dehydration, systemic infection, hospitalization and introduction of a feeding tube should be mentioned as the main determinated effect of oral mucositis. Oral mucositis leads to a decreased quality of life and an increase in treatment costs. Moreover, oral mucositis is a life-threatening disease. In addition to its own direct life-threatening consequences, it can also lead to a reduced survival due to the discontinuation or dose reduction of anti-neoplasm therapy. There are numerous strategies for the prevention or treatment of oral mucositis; however, their effectiveness is limited and does not correspond to expectations. This review is focused on the ghrelin and obestatin as potentially useful candidates for the prevention and treatment of chemo- or/and radiotherapy-induced oral mucositis.
