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

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