Abstract

PURPOSE:This study analyzed associations between preoperative nutritional status and the incidence of early postoperative complications as a primary outcome in patients with oral and oropharyngeal cancer undergoing free flap reconstruction. We hypothesized that preoperative nutritional status may be linked with specific complications, allowing for better preoperative risk assessment. PATIENTS AND METHODS:This longitudinal, retrospective cohort study encompassed 113 patients, all treated surgically for oral and oropharyngeal cancer in the period from March 2013 up to March 2018 in a tertiary referral center. Variables considered were preoperative and postoperative serum albumin and protein values; body mass index; waist-to-hip ratio; circumference of the neck, waist, hip, and thigh; number of cigarettes smoked per day during the 10-year period before surgery; average alcohol consumption; operative time; and postoperative albumin administration. RESULTS:Our study identified preoperative protein serum concentration (≤62 g/L), postoperative albumin administration (≥200 mL), number of cigarettes smoked per day (>20), and prolonged operative time (≥450 minutes) to be associated with postoperative complications. CONCLUSIONS:This is the first study reporting cutoff values of clinical significance in assessing patient preoperative nutritional status in light of reducing postoperative complications after free flap reconstruction.

摘要

目的: 本研究分析了接受游离皮瓣重建的口腔和口咽癌患者术前营养状况与术后早期并发症发生率之间的关系,将其作为主要结局。我们假设术前营养状况可能与特定并发症相关,从而更好地进行术前风险评估。 患者和方法: 这项纵向、回顾性队列研究包括 113 例患者,均在 2013年3月至 2018年3月期间在三级转诊中心接受口腔和口咽癌手术治疗。考虑的变量包括术前和术后血清白蛋白和蛋白值; 体重指数; 腰臀比; 颈部、腰部、臀部和大腿的周长; 手术前 10 年期间每天吸烟的数量; 平均饮酒量; 手术时间; 术后白蛋白给药。 结果: 我们的研究确定了术前蛋白血清浓度 (≤ 62g/L) 、术后白蛋白给药 (≥ 200 mL) 、每天吸烟数量 (>20 支) 、并延长手术时间 (≥ 450 分钟) 与术后并发症相关。 结论: 这是首次报告在评估患者术前营养状况方面具有临床意义的临界值,以减少游离皮瓣重建术后并发症。

METHODS:INTRODUCTION:Human papillomavirus (HPV) is the most common sexually transmitted infection and is associated with several types of cancer. The number of cases of HPV-associated head and neck squamous cell carcinomas (HNSCCs), especially oropharyngeal carcinomas, has increased significantly in recent years despite decreased tobacco smoking rates. Currently, no data concerning the risk factors and prevalence of HPV in HNSCC patients in all regions of Brazil are available, making it difficult to promote advances in this field of public health. Therefore, our goal is to determine the impact of infection by HPV, including HPVs with different genotypes, on head and neck cancer and the risk factors associated with the development of head and neck cancer in all regions of Brazil. METHODS AND ANALYSIS:This is a case-control study that will include 622 patients and 622 controls from all regions of Brazil. A questionnaire will be applied to gather information on sociodemographic, behavioural and health factors. Oral, cervical or penile/scrotal, and anal specimens and serum samples will be collected from all participants. Formalin-fixed paraffin-embedded tissue from tumour biopsies will be analysed only in the case group. Molecular and serological analyses will be performed to evaluate the presence and role of HPV in the development of head and neck cancer. ETHICS AND DISSEMINATION:This project was approved by the research ethical committee of the proposing institution (Hospital Moinhos de Vento, number 2.852.060). Ethical approval from the collaborators is currently under evaluation and is not yet complete. The results of this study will be presented at meetings with the Brazilian Ministry of Health through technical reports and to the scientific community at national and international events, with subsequent publication of scientific articles.

METHODS:BACKGROUND:Factors related to head and neck cancer and the treatment of the disease can affect quality of life. The aim of this study was to determine factors associated with the severity of impact on oral health-related quality of life (OHRQoL) in survivors of head and neck cancer using a multivariate analysis. METHODS:This cross-sectional study evaluated 90 volunteers who had completed radiotherapy at least 3 months earlier. OHRQoL was assessed using oral health impact profile (OHIP-14) and the data were analyzed using robust variance poisson regression models. RESULTS:The mean total OHIP-14 score was 23.98 ± 12.55. Patients with hyposalivation had 56% higher (worse) mean OHIP-14 total scores (CI:1.11-2.18) and patients with advanced stage tumors had 31% higher mean OHIP-14 total scores (CI:1.03-1.66) in multivariate analyses. CONCLUSION:OHRQoL of survivors of head and neck cancer experienced a negative impact following radiotherapy. The impact was associated with hyposalivation and advanced stage tumors.

METHODS:BACKGROUND:To immunohistochemically evaluate the association between the presence of cancer-associated fibroblasts (CAFs) and the tumour expression of podoplanin (PDPN) in head and neck squamous cell carcinoma (HNSCC) and their association with clinicopathological variables. MATERIAL AND METHODS:A tissue microarray (TMA) with biopsy sections from patients diagnosed with HNSCC was stained with antibodies against the CAFs marker, α-smooth muscle actin (α-SMA), and PDPN. We subsequently evaluated their expression to determine the association between them and with clinicopathological variables including age, primary tumour site, TNM stage, and tumour differentiation grade. RESULTS:Positive reaction to α-SMA was observed in the tumour stroma, revealing spindle-shaped cells compatible with CAFs, which showed a high expression in 62% of cases and a significant association with laryngeal carcinomas, advanced clinical stages, and lower tumour differentiation (P ≤ 0.05). PDPN staining on tumour cells showed low expression in 72% of cases, and it was not associated with any clinicopathological variable or with the presence of CAFs. CONCLUSIONS:The presence of CAFs in the tumour stroma is related to an aggressive phenotype and could increase as the disease progresses, although based on our findings, it would have no relationship, at least directly, with the expression of PDPN.
