Abstract

:BACKGROUND To compare the effects of chemotherapy dose escalation on survival and prognosis of nasopharyngeal carcinoma (NPC) patients who developed bone-only metastasis. MATERIAL AND METHODS Between October 2000 to March 2017, 58 NPC patients with initial bone-only metastasis were retrospectively analyzed. Patients who received <6 or ≥6 cycles of chemotherapy were matched and grouped using receiver operating characteristic curve (ROC) analysis. Overall survival (OS) was assessed using the Kaplan-Meier method, log-rank test, and Cox regression analysis. RESULTS The median OS for the entire group was 24 months, while the 1-, 2-, and 3-year OS rates were 78.5%, 49.4%, and 26.8%, respectively. The median OS for patients who received <6 cycles of chemotherapy was 21 months, with 1-, 2-, and 3-year OS rates of 64.8%, 34.3%, and 17.2%, respectively. The median OS of patients who received ≥6 cycles of chemotherapy was 26 months, with 1-, 2-, and 3-year OS rates of 92.6%, 54.9%, and 30.9%, respectively. Multivariate analysis showed that the number of metastatic sites (≥3 vs. <3) and chemotherapy cycles (<6 vs. ≥6) were independent prognostic factors for OS. CONCLUSIONS NPC patients who had less than 3 bone metastatic sites and who received ≥6 cycles of chemotherapy had better survival and prognosis.

摘要

背景: 比较化疗剂量递增对发生骨转移的鼻咽癌患者生存和预后的影响。材料与方法回顾性分析 2000 年 10 月至 2017 年 3 月收治的 58 例初治鼻咽癌骨转移患者的临床资料。使用受试者工作特征曲线 (ROC) 分析对接受 <6 或 ≥ 6 个周期化疗的患者进行匹配和分组。采用 Kaplan-Meier 法、 log-rank 检验和 Cox 回归分析评估总生存期 (OS)。结果全组中位 OS 为 24 个月,1 、 2 、 3 年 OS 率分别为 78.5% 、 49.4% 、 26.8%。接受 <6 个周期化疗的患者的中位 OS 为 21 个月,1 、 2 和 3 年 OS 率分别为 64.8% 、 34.3% 和 17.2%。接受 ≥ 6 个周期化疗的患者中位 OS 为 26 个月,1 、 2 、 3 年 OS 率分别为 92.6% 、 54.9% 、 30.9%。多因素分析显示,转移部位数目 (≥ 3 个 vs. <3 个) 和化疗周期数 (<6 个 vs. ≥ 6 个) 是 OS 的独立预后因素。结论接受 ≥ 6 个周期化疗的鼻咽癌骨转移部位 <3 个的患者生存及预后较好。

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.
