    Abstract Background: This study retrospectively analyzed the risk factors for oral mucositis (OM) during cetuximab treatment.
    Material and methods: We screened patients using cetuximab and retrospectively evaluated the presence of OM based on medical records. We collected information from 2 years of evaluations. Patient medical records were reviewed to obtain data on chemotherapy cycle and dose, sex, age, primary tumor, TNM stage, and head and neck radiotherapy (HNR) history. The X2 test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p < 0.05).
    Results: Among 1831 patients, OM was showed in 750 in any grade (41%), during cetuximab treatment. Most patients were female (n=944, 51.6%), <70years-old (n=1149, 62.8%), had larynx cancer (n=789, 43.1%) in T4 (n=579, 47.7%), N0 (n=509, 52.6%) stages. Primary tumor surgery was performed in 1476 (80.6%) patients, radiotherapy in 606 (33.1%) patients and cetuximab protocols most used involved up to four cycles (n=1072, 58.5%) of <400mg (n=996, 54.4%) cetuximab doses. Female (OR [odds ratio] = 2.17, CI95% = 1.26-3.75), >70 years-old patients (OR = 16.02, CI95% = 11.99-21.41), with HHNR (OR = 1.84, 1.41-2.40), treated with >4 cycles (OR = 1.52, CI95% = 1.16-2.01) and high doses of cetuximab (OR = 3.80, CI95% = 2.52-5.71) are the greatest risk factors for OM.
    Conclusions: Since the clinical benefit of cetuximab in the treatment of older patients is limited and there is a high OM, especially in women with head and neck treated with radiotherapy, high doses and a high number of cetuximab cycles must be administered with caution.

    Abstract Background: Preventive Photobiomodulation Therapy (PBMT) significantly reduces oral mucositis (OM) severity in patients undergoing Radiochemotherapy (RCT) for the treatment of oral cancer, but daily applications generate cost, overload the dental team, and reduce the number of patients assisted.To evaluate the effectiveness of two PBMT protocols in preventing OM in patients undergoing RCT for oral cancer.
    Material and methods: 16 patients diagnosed with oral cancer undergoing RCT were included, equally divided into two groups: a group treated daily with PBMT, and another group also submitted to daily treatment, however, performing the application of PBMT every three days, interspersed with a simulation of PBMT (placebo). A red laser was used (~660 nm), 0.1W power, 1J of energy applied per point, 9 points per area (labial mucosa, buccal mucosa, lateral borders of the tongue, body of the tongue, and floor of the mouth) from the beginning of RCT until the end of the oncological treatment. Daily assessments were performed regarding OM scores, the World Health Organization (WHO) pain scale, and the visual analog scale (VAS). Weight, salivary flow (SGAPP), OHIP-14, and DMFT were evaluated on the initial and final days of RT. OM incidence and clinical data were compared by Pearson's chi-square test or Fisher's exact test. Pain and other scale scores were compared using the Mann-Whitney and Friedman/Dunn tests (SPSS v20.0 p<0.05).
    Results: In the group with PBMT on alternate days, there was an increase in the frequency of grade 2 and grade 3 oral mucositis and an increased risk of grade 2 oral mucositis, in addition to higher mean pain scores and greater reduction in salivary flow.
    Conclusions: The daily PBMT protocol proved more effective in controlling the frequency and severity of OM, pain, and salivary flow.

    Abstract Background: Chemotherapy (QT) is a systemic treatment using a combination of antineoplastic drugs, orally or intravenously, that inhibit tumor growth and fast-growing normal cells. Due to its nonspecificity, chemotherapy can cause a series of adverse effects, such as altered taste (dysgeusia), associated with malnutrition and, consequently, other adverse effects in the gastrointestinal tract and increased mortality risk. This study aimed to evaluate the influence of dysgeusia on the incidence of other adverse effects and overall survival during antineoplastic chemotherapy (chemotherapy).
    Material and methods: An observational, retrospective, cross-sectional study was conducted using data from the Electronic Health Record system of the Cancer Institute of Ceará over two years. Before the CT session, the multi-professional team evaluated the patient for the presence and severity of adverse effects (AE), using scores from the CTCAE v5.0 scale. Dysgeusia scores were collected and associated with clinical pathological data, with other adverse effects (nausea, vomiting, diarrhea, oral mucositis, anorexia, constipation), and with overall survival. Chi-square and Mantel-Cox log-rank tests were used.
    Results: Of 5744 patients evaluated, dysgeusia presented a frequency of 50.6%, being directly associated with female gender (p=0.001), overweight (p=0.022), high tumor stages (p=0.009), a combination of adjuvant and neoadjuvant (p=0.010) and four-year survival (p=0.030). Dysgeusia frequency was directly associated with diarrhea (p<0.001), anorexia (p<0.001), oral mucositis (p<0.001), nausea (p<0.001), constipation (p<0.001) and vomiting (p<0.001), and inversely associated with fatigue (p=0.035).
    Conclusions: Dysgeusia during CT increases the risk of other adverse effects and negatively impacts prognosis.

    Abstract Background: This study retrospectively analyzed the risk factors for transchemotherapy oral mucositis (OM).
    Material and methods: Before each chemotherapy cycle, patients were routinely evaluated for the presence/severity of OM based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale for adverse effects and graded as follows: However, specific conditions such as mucositis are graded on a five-point scale: 0, absence of mucositis, grade 1 (Asymptomatic or mild), 2 (Presence of pain and moderate ulceration, without interference with food intake), 3 (severe pain with interference with food intake) or 4 (Life-threatening with the need for urgent intervention). Information from 2 years of evaluations was collected and patient medical records were reviewed to obtain data on chemotherapy cycle, sex, age, body mass index, body surface area, primary tumor, chemotherapy protocol, and history of head and neck radiotherapy. The X² test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p<0.05).
    Results: Among 19,000 total evaluations of 3,529 patients during 5.32±4.7 chemotherapy cycles (CT) the prevalence of OM was 6.3% (n=1,195). Chemotherapy duration (p<0.001), female sex (p=0.001), adjuvant intention (p=0.008) and the use of carboplatin (p=0.001), cisplatin (p=0.029), docetaxel (p<0.001) and bevacizumab (p=0.026) independently increased the risk of mucositis. In head and neck tumors, 2018 year (p=0.017), chemotherapy duration (p=0.018), BMI>30 (p=0.008), radiotherapy (p=0.037) and use of carboplatin (p=0.046) and cyclophosphamide (p=0.010) increased this prevalence.
    Conclusions: Cycles of chemotherapy, sex, cytotoxicity drugs, bevacizumab and head and neck radiotherapy increase the risk of OM in solid tumors.
