Giacomelli, I., Scartoni, D., Fiammetta, M., Baki, M., Zei, G., Muntoni, C., . . . Livi, L. (2015). Oral lapacho-based medication: An easy, safe, and feasible support to prevent and/or reduce oral mucositis during radiotherapy for head and neck cancer. Nutrition and Cancer, 67, 1249–1254. 

To demonstrate the benefits and tolerance of a multicomponent herbal oral agent for mucositis in patients with head and neck cancer receiving radiation or combination therapy

Orasol plus solution (a mixture of lapacho, hyaluronic acid, green tea, calendula, erisiom, propolis, marigold, plantain, and mauve) was administered to patients from the first day of radiotherapy until the end of therapy. It was given at a dose of 10 ml three times daily. The authors indicated that it can be swallowed, but did not state how patients were instructed to use it.

• N = 40
• AGE = 70% were older than 60 years
• MALES: 68%, FEMALES: 32%
• KEY DISEASE CHARACTERISTICS: Patients had head and neck cancer. The primary site of cancer was the oral cavity in 30% of patients and the hypopharynx in 30%. In addition, 72.5% were getting radiation only, and the rest were getting radiation and chemotherapy
• OTHER KEY SAMPLE CHARACTERISTICS: Thirty-five percent were current smokers.

• SITE: Single site  
• SETTING TYPE: Not specified  
• LOCATION: Italy

• PHASE OF CARE: Active antitumor treatment

• Phase II prospective trial

• Common Terminology Criteria for Adverse Effects (CTCAE) version 4

Of the patients, 47.5% developed grade 1, 27.5% developed grade 2, and 10% developed grade 3 mucositis. Median Gy doses to the oral mucosa were lowest in those with grade 1 mucositis. Six patients did not develop mucositis. None of these patients was receiving radiation and chemotherapy. The prevalence of grade 2 or greater mucositis was higher among smokers (p < 0.02). One patient developed itching and one developed glossitis. Twenty-five percent needed an increase in dosage or additional analgesic therapy.

The herbal nutritional supplement tested here may have some benefit for the prevention of severe mucositis in patients with head and neck cancer during therapy. Additional research is needed to establish any benefit.

• Small sample (< 100)
• Baseline sample/group differences of import
• Risk of bias (no control group)
• Risk of bias (no blinding)
• Risk of bias (no random assignment)
• No information is given regarding patient adherence to use. The sample was too small for subgroup analysis for those getting combination chemoradiation therapy.

Very few interventions have been shown to be effective for the prevention and treatment of oral mucositis in patients receiving cancer treatment. The substance tested here appeared safe, and findings suggest that it may be beneficial; however, numerous study design limitations exist. Further research with this agent is needed to determine efficacy.
