RESUMO

Cancer disclosure represents a complex healthcare dynamic. Physicians or caregivers may be prompted to withhold diagnosis information from patients. This study aims to comprehensively map and synthesize available evidence about diagnosis nondisclosure regarding head and neck cancer (HNC) patients. Following the Joanna Briggs Institute guidelines, a scoping review was conducted across major databases without period restriction, yielding 9238 publications. After screening and selection, a descriptive synthesis was conducted. Sixteen studies were included, primarily conducted in academic settings (75%) from Europe and Asia, with a total population of 662 patients predominantly diagnosed with brain, oral, pharyngeal, or laryngeal tumors. Remarkably, 22.51% of patients were unaware of their diagnosis. Although physicians were the main source of diagnostic information (35%), they reported to often use vague terms to convey malignancy. Additionally, 13.29% of patients were aware of their diagnosis from sources other than doctors or caregivers. Caregivers (55%) supported diagnosis concealment, and physicians tended to respect family wishes. A high diagnosis-to-death interval, education, and age significantly influenced diagnosis disclosure. HNC patients expressed a desire for personalized open communication. Multiple factors influenced the decision on diagnosis disclosure. Current evidence on this topic varies significantly, and there is limited research on the consequences of nondisclosure. These findings reflect the underestimation of the patients' outlook in the diagnosis process and highlight the need for further research, aiming to establish open communication and patient autonomy during the oncological journey.

RESUMO

Diverse proteomics-based strategies have been applied to saliva to quantitatively identify diagnostic and prognostic targets for oral cancer. Considering that these targets may be regulated by events that do not imply variation in protein abundance levels, we hypothesized that changes in protein conformation can be associated with diagnosis and prognosis, revealing biological processes and novel targets of clinical relevance. For this, we employed limited proteolysis-mass spectrometry in saliva samples to explore structural alterations, comparing the proteome of healthy control and oral squamous cell carcinoma (OSCC) patients with and without lymph node metastasis. Thirty-six proteins with potential structural rearrangements were associated with clinical patient features including transketolase and its interacting partners. Moreover, N-glycosylated peptides contribute to structural rearrangements of potential diagnostic and prognostic markers. Altogether, this approach utilizes saliva proteins to search for targets for diagnosing and prognosing oral cancer and can guide the discovery of potential regulated sites beyond protein-level abundance.

RESUMO

The dental treatment of patients with oral cavity and oropharyngeal squamous cell carcinoma (OOPSCC) may be challenging for dentists. This study aimed to characterize systemic changes in patients with OOPSCC undergoing dental treatment prior to cancer therapy, with a specific focus on laboratory assessments. The primary objectives included identifying potential adverse events, such as infections or bleeding, resulting from dental procedures. Additionally, the study aimed to correlate baseline patient characteristics with treatment-related toxicities. This was a prospective cohort study that included 110 OOPSCC patients referred to the Dental Oncology Service at São Paulo State Cancer Institute, Brazil, between November/2019 and December/2020. Comorbidities, sociodemographic data, medication in use, cancer treatment-related toxicities, and altered laboratory tests results were correlated. The most common comorbidities and altered laboratory results were hypertension, dyslipidemia, diabetes, as well as elevated levels of C-reactive protein, hemoglobin, and hematocrit. Toxicities exhibited a progressive pattern over time, encompassing oral mucositis (OM), xerostomia, dysphagia, dysgeusia, trismus, and radiodermatitis. No correlation between comorbidities and cancer treatment-related toxicities, a positive correlation between medications in use and OM, and a negative correlation between medications and dysgeusia were found. OM was associated with altered thyroxine (T4) and free thyroxine (FT4), calcium, urea, creatinine, alkaline phosphatase, and syphilis. Family income and housing were OM predictors. Altered T4/FT4/urea/calcium/alkaline phosphatase/creatinine/syphilis may be useful clinical predictors of OM. Despite the elevated prevalence of comorbidities and abnormal laboratory findings, dental treatment prior to cancer treatment yielded no adverse events.

RESUMO

OBJECTIVES: This project aimed to promote evidence-based practices relat. ed to the oral health of critically ill patients in an intensive care unit in Brazil. INTRODUCTION: The oral hygiene of patients on mechanical ventilation is an essential component of nursing care quality, and well-defined guidelines ensure appropriate care. Mechanical ventilation is associated with the risk of ventilator-associated pneumonia, which can increase mortality, length of stay, time on mechanical ventilation, and hospital costs. METHODS: This project was guided by the JBI Evidence Implementation Framework, which consists of seven stages: (1) identification of the area of practice to be changed, (2) involvement of change agents, (3) context assessment and readiness for change, (4) review of practices against evidence-based audit criteria, (5) implementation of practice changes, (6) reassessment of practices using a follow-up audit and (7) consideration of the sustainability of changes in practice. RESULTS: Four audit criteria were developed to evaluate compliance with best practices. In the follow-up audit, Criteria 1, 2, and 3 obtained compliance of ≥ 80%. Thus, for Criterion 1, all the patients on mechanical ventilation for more than 24 hours were evaluated by the oral medicine team, resulting in 100% compliance. For Criterion 2 on appropriate oral hygiene measures, a compliance rate of 80% was achieved. For Criterion 3, 39 professionals (90.7%) participated in educational activities related to the oral health protocol for critically ill patients, obtaining 90.7% compliance. For Criterion 4 regarding patients being evaluated before receiving any oral health care, improvement was low (only 50%), revealing the need for further improvement. CONCLUSION: This best practice project improved the professional practice of nursing staff and increased compliance with best practices for the oral health of critically ill patients.

RESUMO

In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world.

RESUMO

AIMS: Radiation caries (RC) is a highly prevalent and chronic complication of head and neck radiotherapy (HNRT) and presents a challenge for clinicians and patients. The present study aimed to assess the impact of RC on the morbidity and mortality outcomes of head and neck squamous cell carcinoma (HNSCC) patients. METHODS AND RESULTS: Patients were divided into three groups: (1) RC (n = 20), (2) control (n = 20), and (3) edentulous (n = 20). Information regarding the number of appointments, dental procedures, osteoradionecrosis (ORN), prescriptions, and hospital admissions were collected. Mortality outcomes were assessed through disease-free survival (DFS) and overall survival (OS) rates. RC patients required more dental appointments (p < .001), restorations (p < .001), extractions (p = .001), and antibiotic and analgesic prescriptions (p < .001). Kaplan-Meier subgroup analyses showed a significantly increased risk of ORN in RC compared to edentulous patients (p = .015). RC patients presented lower DFS rates (43.2 months) than the control and edentulous groups (55.4 and 56.1 months, respectively). CONCLUSIONS: RC impacts morbidity outcomes among cancer survivors due to increased demand for medication prescriptions, multiple specialized dental appointments, invasive surgical treatments, increased risk of ORN, and increased need for hospital admissions.

RESUMO

OBJECTIVE: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. METHODS: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square. RESULTS: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC-dn, while s-OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. CONCLUSIONS: In Latin America, OSCC-dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon.

RESUMO

BACKGROUND: The available literature regarding metastasis to the oral cavity from colorectal cancer, especially rectal cancer, is currently limited. With this in mind, we aimed to report the first case of rectal adenocarcinoma metastasis to the oral vestibule. CASE REPORT: A 36-year-old Caucasian female with a 17-months history of rectal adenocarcinoma and several metastases was referred to the Dental Oncology Service due to a nodular swelling in the oral cavity. Intraoral examination showed a large, painless nodule with superficial necrosis on the right side of the mandibular vestibule. An incisional biopsy was performed, and the microscopic analysis demonstrated an infiltrative tumor characterized by islands of malignant epithelial cells with a columnar appearance and tubular pattern. The epithelial component presented pseudoductal structures resemble intestinal mucosa, which exhibited intraluminal secretion. The neoplastic cells were immunoreactive for CDX2 and Cytokeratin 20, and negative for Cytokeratin 7. Therefore, the final diagnosis of metastatic rectal adenocarcinoma was established. Unfortunately, the patient died 23 months after the diagnosis of the primary tumor. CONCLUSION: The study highlights that metastases to the oral cavity should be considered in the differential diagnosis of large reactive lesions affecting young patients, especially in the setting of a patient history of cancer.
