Abstract

Introduction:2019 novel coronavirus disease (COVID-19) outbreaks have been occurring in China and other countries in the world. To prevent further spread of the disease, restrictions of population flow from the government and measures to reduce virus transmission from hospitals may lead to the delay of diagnosis and treatment in patients with nasopharyngeal carcinoma (NPC). Methods:All NPC patients with radiotherapy indications were included from 20 weekdays before (group A) and after (group B) January 31, 2020, when the institute began to take measures against COVID-19. The waiting intervals of each step and variation from the diagnosis and treatment path of NPC between two groups were compared. Results:Significant differences were found between the group A and group B in the median waiting days for pathological biopsy (5 vs 15, P=0.012), radiotherapy immobilization and simulation (3.5 vs 16.5, P<0.001), validation of position and plan (20 vs 61, P<0.001) and initiation of radiotherapy (28 vs 36, P=0.005). During the waiting period of radiotherapy, 32.4% of the NPC patients received an additional one cycle of chemotherapy to the original treatment strategy. Conclusion:The prevalence of COVID-19 caused delay in the diagnosis and treatment of NPC patients to a certain extent. Additional chemotherapy could be considered to counteract the effect of treatment delay. More specific measures should be taken to balance the risk of delayed diagnosis and treatment of NPC and infection of COVID-19.

摘要

导读: 我国和世界其他国家已发生 2019 起新型冠状病毒 (新型冠状病毒肺炎) 疫情。为了防止疾病的进一步传播,来自政府的人口流动限制和减少医院病毒传播的措施可能导致鼻咽癌 (NPC) 患者诊断和治疗的延误。 办法: 一切有放疗指征的鼻咽癌患者均从 20 个平日的术前 (A 组) 和术后 (B 组) 2020 年 1 月 31 日,本院开端采取新型冠状病毒肺炎办法。比较两组各步骤的等待间隔时间和鼻咽癌诊断和治疗路径的变化。 结果: A 组和 B 组在病理活检 (5 vs 15,P = 0.012) 、放疗固定和模拟 (3.5 vs 16.5, P<0.001),位置和计划的验证 (20 vs 61,P<0.001) 和开始放疗 (28 vs 36,P = 0.005)。在放疗等待期间,32.4% 的鼻咽癌患者在原治疗策略的基础上增加了一个周期的化疗。 结论: 新型冠状病毒肺炎在一定程度上延误了鼻咽癌的诊治。可以考虑额外的化疗来抵消治疗延迟的影响。应采取更具体的措施来平衡鼻咽癌延误诊治和新型冠状病毒肺炎感染的风险。

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.
