Abstract
Purpose: To evaluate the non-inferiority of protocols with red (R) or infrared (IR) lasers alone when compared to the already established protocol of R + IR lasers.
Methods: This is a phase III, randomized, triple-blind, non-inferiority, placebo-controlled clinical trial consisting of three study groups (n = 60/group): one receiving R + IR lasers, one receiving only R-laser and IR-placebo and the third with IR-laser and R-placebo (2 J of R-laser and 3 J of IR-laser) in 23-points symmetrically distributed on the tongue. Clinicopathological, sociodemographic data, hematological tests, taste analysis, subjective taste scales (VAS, CTCAE, and STTA), Quality-of-life (OHIP-14), ECOG general health status, body mass index (BMI), CPOD, salivary flow, and other side effects were collected. Chi-square/Fisher's exact tests and Kruskal-Wallis/Dunn (intergroup-analysis) or Friedman/Dunn (intragroup-analysis) tests were used (Margin of non-inferiority: 2-tailed p < 0.05).
Results: In the R + IR group, the objective did not reduce significantly (p = 0.873), but in the R-group, there was a significant reduction of taste function (p = 0.020). VAS (p < 0.001), CTCAE (p < 0.001), STTA (p < 0.001), and OHIP-14 (p < 0.001) analysis in the IR-group was significantly worse than the R + IR group. The ECOG parameter showed an improvement in the R + IR group (20%) compared to the R (11.7%) or IR (6.7%) groups over the course of the CT cycles (p = 0.037). There was no difference in BMI (p = 0.251), but the R + IR group gained significantly more weight (p = 0.044) without an increase in the frequency of obesity (p = 0.850). Groups R (p < 0.001) and IR (p = 0.046), but not R + IR (p = 0.369), showed a reduction in salivary flow.
Conclusion: Protocols R or IR proved to be inferior to the R + IR laser photobiomodulation protocol.
期刊介绍：
Supportive Care in Cancer provides members of the Multinational Association of Supportive Care in Cancer (MASCC) and all other interested individuals, groups and institutions with the most recent scientific and social information on all aspects of supportive care in cancer patients. It covers primarily medical, technical and surgical topics concerning supportive therapy and care which may supplement or substitute basic cancer treatment at all stages of the disease.
Nursing, rehabilitative, psychosocial and spiritual issues of support are also included.
