Inclusion criteria

Inclusion criteria: The criteria for inclusion in the study covered adults over 18 years of age of both sexes with a confirmed histopathological diagnosis of head and neck squamous cell carcinoma (HNSCC) in locations such as the base of the tongue, other or unspecified parts of the tongue, gums, floor of the mouth, palate, other parts or unspecified parts of the mouth, tonsils, oropharynx, pyriform sinus, hypopharynx and other ill-defined locations in the lip, oral cavity or pharynx, as well as patients with a confirmed histopathological diagnosis of other types of cancer in regions such as the prostate, urinary bladder, rectum, anus, breast and cervix, including prostate adenocarcinoma, metastasis in other organs of the urinary system, carcinoma in situ of the prostate , penile cancer, squamous cell carcinoma of the anal canal, squamous cell carcinoma of the cervix, adenocarcinoma of the cervix, esophageal cancer, ductal carcinoma in situ of the breast or others specified or unspecified malignant neoplasms. All participants, regardless of cancer type, were receiving 3D conformal radiotherapy (3D-RT), alone or in combination with chemotherapy

Exclusion criteria

Exclusion criteria: patients who had already undergone radiotherapy for head and neck cancer; presence of oral mucositis at the beginning of the study; use of pacemakers; refusal to participate; history of alcohol or drug abuse; diagnosis of cardiac, renal, gastrointestinal, hepatic, pulmonary, neurological, psychiatric, hematological or metabolic diseaes

Design outcomes

Primary

MeasureTime frame
expected outcome 1 is to find changes in the impedance, resistance, reactance, phase angle and capacitance modules after radiotherapy;Outcome found 1 there is an association between an increase in the values ??of impedance modules, resistance, reactance, phase angle and capacitance with the appearance of mucositis

Secondary

MeasureTime frame
expected outcome 2 is to find relationship among changes in the impedance, resistance, reactance, phase angle, capacitance modules and oral mucositis;Outcome found 2 there is an association among the values ??of impedance modules, resistance, reactance, phase angle, capacitance and the appearance of mucositis
