简要总结
Patients undergoing hematopoietic cell transplantation (HSCT) receive high doses of chemotherapy with or without radiotherapy to eradicate the underlying disease, which induces a series of adverse effects, including in the oral cavity. Among the most common oral lesions is oral mucositis (OM), which has been associated with greater morbidity and important biological and economic impact.Currently, photobiomodulation (PBM) with intraoral application has been recommended for the prevention of OM, however, few studies have evaluated the impact of its extraoral use.
详细描述
The main objective of this study is to evaluate the effectiveness of extraoral PBM using unfocused high-power laser compared to intraoral PBM with low-power laser in the management of OM, mouth pain, functional capacity, development and duration of hyposalivation and xerostomia and quality of life. This is a multicenter, randomized, single blind clinical trial to be conducted at the Hospital de Clínicas de Porto Alegre (HCPA) and at the AC Camargo Cancer Center Hospital.
All patients who accept participate of the study will assign an informed consent form. For data management, the REDcap® software will be used, where all forms referring to patients evaluation will be incorporated. 42 patients will be selected who will undergo HSCT regardless of the underlying disease. Subsequently, upon accepting participation in the study, participants will undergo a sequential allocation using the R shiny summary statistics ® software by the variables of gender, age, type of HSCT and type of conditioning and will be allocated into 2 groups: Group I : intraoral photobiomodulation (660nm, 100mW, 10 J/cm 2 , 3 s/point) (PBMI, n=21) and Group II: extraoral photobiomodulation (810 + 980 nm,1 W,6.11 J/cm 2, 30 s/point) with high power extraoral unfocused laser with 1 W power (PBME, n=21). In both arms, the patients will receive photobiomodulation therapy from the the beginning of the conditioning until D + 5 after HSCT procedure. If any patient presenting or developing lesion after D + 5, this patient will receive the photobiomodulation protocol stipulated in your respective group util occur the healing of the lesion.
The study will be carried out by a dental surgeon who will carry out the initial assessment and reassessments (blinded to the groups) and another who will carry out the application of the PBM. Patients will be evaluated daily from the beginning of the conditioning until the bone marrow grafting or while there are oral lesions.
If they do not develop lesions, after bone marrow grafting, the patients will be evaluated weekly until hospital discharge. After clinical exam, grade and OM severity will be evaluated, after that, classified according WHO and NCI scale, pain assessment (VAS and NRS-101) and functional assessment, until D + 5 after HSTC procedure. The evaluation of xerostomia/hyposalivation (stimulated and non-stimulated salivary flow and xerostomia inventory) and quality of life will be performed in three moments, at the beginning of the conditioning, on the day of the HSCT and on the bone marrow marrow grafting day.
Saliva samples will be collected with SWABS, to futures microbioma analysis. The statistical analyzes will be carried out in the PASW 18.0 program, initially the evaluation of the data distribution will be carried out from the application of the Shapiro-Wilk and Kolmogorov-Smirnov tests.

结局指标
主要结局
Oral Mucositis evaluation according WHO scale
时间窗: 16 months
The measurement of mucositis will be performed daily from the beginning of the conditioning therapy until the bone marrow grafting or while there are oral lesions. Mucositis will be scored according to WHO criteria: grade 0 (none), grade I (oral soreness, erythema), grade II (oral erythema, ulcers, solid and liquid diet tolerated), grade III (oral ulcers, liquid diet only), and grade IV (oral diet impossible).
Oral Mucositis evaluation according NCI scale
时间窗: 16 months
The measurement of mucositis will be performed daily from the beginning of the conditioning therapy until the bone marrow grafting or while there are oral lesions. The National Cancer Institute (NCI) scale (NCI - Common Terminology Criteria for Adverse Events) will be performed: grade I (mucosal erythema), grade II ( patchy ulcerations with pseudomembranes), grade III (confluent ulceration or pseudomembranes, bleeding with minor trauma), and grade IV (tissue necrosis, significant spontaneous bleeding)
