The effect of treatment delay on quality of life and overall survival in head and neck cancer patients. Eur J Cancer Care (Engl) 2022; 31:e13589. [PMID: 35438210 PMCID: PMC9541370 DOI: 10.1111/ecc.13589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 01/21/2022] [Accepted: 03/28/2022] [Indexed: 11/28/2022]
Abstract
Objective Head and neck squamous cell carcinomas (HNSCC) are rapidly developing tumours, and substantial delay in treatment initiation is associated with decreased overall survival. The effect of delay on health‐related quality of life (HRQOL) is unknown. The aim of this study was to assess the impact of delay on QOL and overall survival. Methods Patients with mucosal HNSCC were prospectively included. HRQOL and 2‐year overall survival were analysed using linear mixed‐model analyses and cox regression, respectively. Delay was defined as care pathway interval (CPI) of ≥30 days between first consultation and treatment initiation. Results Median CPI was 39 days for the 173 patients included. A trend towards higher HRQOL‐scores (indicating better HRQOL) during 2‐year follow‐up for patients with delay in treatment initiation was visible in the adjusted models (HRQOL summary score—β: 2.62, 95% CI: 0.57–4.67, p = 0.012). Factors associated with decreased overall survival were moderate comorbidities (HR: 5.10, 95% CI: 1.65–15.76, p = 0.005) and stage‐IV tumours (HR: 12.37, 95% CI: 2.81–54.39, p = 0.001). Delay was not associated with worse overall survival. Conclusion Timely treatment initiation is challenging, especially for patients with advanced tumours and initial radiotherapy treatment. Encountering delay in treatment initiation did not result in clinically relevant differences in HRQOL‐scores or decreased overall survival during 2‐year follow‐up.

Abstract
OBJECTIVE Osteoradionecrosis (ORN) of the jaw is preceded by dental extractions in up to 10% of cases. We present a case series of post-radiotherapy patients undergoing dental extractions who have received the prophylactic antifibrotic agents pentoxifylline and vitamin E (PVe) to prevent ORN. STUDY DESIGN A retrospective review was conducted of 219 patients with head and neck cancer (HNC) undergoing 1079 dental extractions between 2009 and 2020. Data regarding oncological treatment, prophylactic drug regimen, dental history, and clinical outcome was collected. RESULTS Twelve patients developed ORN at 17 extraction sites (ORN rates, 1.6% and 5.5% at tooth level and patient level, respectively). PVe regimen compliance significantly decreased ORN rates at the patient level (3.4% vs 11.5%; P < .03) and the tooth level (1.0% vs 3.5%; P < .01) compared with no PVe. Regimen compliance significantly reduced ORN rates in patients with oropharyngeal cancer (P < .01); in those with mandibular (P < .005) molar (P < .003), and flapless extractions (P < .04); in patients with radiation regions >40 Gy (P < .0009); and in those who underwent primary closure (P < .03). Machine learning analysis identified almost all these factors as influential at a tooth level for ORN. CONCLUSIONS PVe regimen compliance decreased dental extraction ORN rates more than the literature base rates of 7% at the patient level and 2% at the tooth level. Given its success in managing existing ORN, PVe could be extended prophylactically for dental extractions in irradiated patients with head and neck cancer.

Abstract
INTRODUCTION Head and neck cancers (HNC) are relatively fast-growing tumours, and delay in treatment initiation is associated with tumour progression and adverse outcome. An overview of factors contributing to delay can provide critical insights on necessary adjustments to optimize care pathways. This systematic review aims to identify factors associated with delay and summarize the effect of delay on oncological outcome measures. METHODS A search strategy was conducted according to PRISMA guidelines to search electronic databases for studies assessing the carepathway interval (days between first visit in head and neck oncology center and treatment initiation) and/or time-to-treatment-initiation interval (days between histological diagnosis and treatment initiation) and 1) determinants of delay and/or 2) effect of delay on outcome within these timeframes. Due to heterogeneity between included studies, a meta-analysis was not possible. RESULTS Fifty-two studies were eligible for quantitative analysis. Non-Caucasian race, academic setting, Medicaid/no insurance and radiotherapy as primary treatment were associated with delay. Advanced tumour stage was related to increased time-to-treatment initiation in the four common sites combined (oral cavity, oropharynx, hypopharynx, larynx). Separate determinants for delay in different tumour locations were identified. In laryngeal, oral cavity cancer and the four common HNC sites combined, delay in start of treatment is associated with decreased overall survival, although no cut-off time point could be determined. CONCLUSION Race, facility type, type of insurance and radiotherapy as primary treatment were associated with delay and subsequent inferior survival in the four common sites combined.

Abstract
INTRODUCTION Smoking is well-known to increase cancer risk, particularly risk of lung cancer, and negatively affects efficacy of cancer treatment. However, recent evidence suggests that among cancer patients, paradoxically, smokers respond to treatment better than non-smokers. We propose to conduct a focused review and meta-analysis to compare response to drug treatment between smoking and non-smoking cancer patients. METHODS AND DESIGN We will collect data from large clinical trials of therapies for cancer patients which have included smokers and non-smokers. We will search PubMed, PMC/ MEDLINE, SCOPUS, Embase, and the registries for clinical trials and four major clinical journals up to June 30, 2019. Search terms will be "Drug name" phase-3" or "Drug name" phase-III." Data collection will be focused on randomized clinical trials of cancer drugs that enrolled at least 100 participants and reporting treatment results from smoking and nonsmoking patients. Initial selection criteria will be clinical trial studies of drug treatment of 100 or more cancer patients, and reporting hazard ratios (HR) for smokers and non-smokers. Two persons will be searching such publications independently, or data will be provided, double checked, or confirmed by authors. Multiple sub-group analyses will be conducted by at least two persons to avoid bias or experimental errors. DISCUSSION The results will clarify whether smoking and response to treatment of cancer are linked not. Our results may possibly identify drug/s that work better among cancer patients who are smokers. TRIAL REGISTRATION PROSPERO registration number: CRD42019146402.

Abstract
BACKGROUND In head and neck cancer (HNC), the relationship between a delay in starting radiotherapy (RT) and the outcome is unclear. The aim of the present study was to determine the impact of the amount of time before treatment intervention (TTI) and the growth kinetics of individual tumors on treatment outcomes and survival. METHODS Two hundred sixty-two HNC patients with 273 primary tumors, treated with definitive (chemo) RT, were retrospectively analyzed. The TTI was defined as the time interval between the date of histopathologic diagnosis and the first day of the RT course. Volumetric data on 57 tumors were obtained from diagnostic and RT planning computer tomography (CT) scans in order to calculate the tumor growth kinetic parameters. RESULTS No significant association between locoregional control or cause-specific hazards and TTI was found. The log hazard for locoregional recurrence linearly increased during the first 40 days of waiting for RT, although this was not significant. The median tumor volume relative increase rate and tumor volume doubling time was 3.2%/day and 19 days, respectively, and neither had any impact on locoregional control or cause-specific hazards. CONCLUSION The association between a delay in starting RT and the outcome is complex and does not harm all patients waiting for RT. Further research into imaging-derived kinetic data on individual tumors is warranted in order to identify patients at an increased risk of adverse outcomes due to a delay in starting RT.

The association between rs16917496 T/C polymorphism of SET8 gene and cancer risk in Asian populations: a meta-analysis. Biosci Rep 2018; 38:BSR20180702. [PMID: 30341251 PMCID: PMC6239252 DOI: 10.1042/bsr20180702] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Revised: 09/30/2018] [Accepted: 10/14/2018] [Indexed: 01/03/2023] Open
Abstract
Epidemiological studies have demonstrated close associations between SET8 rs16917496 T/C polymorphism and cancer risk, but the results of published studies were not consistent. We therefore performed this meta-analysis to explore the associations between rs16917496 T/C polymorphism and cancer risk. Five online databases were searched. Odds ratios (ORs) with a 95% confidence interval (CI) were calculated to assess the association between rs16917496 T/C polymorphism and cancer risk. In addition, heterogeneity, accumulative, sensitivity analysis, and publication bias were conducted to check the statistical power. Overall, 13 publications involving 5878 subjects were identified according to included criteria. No significant cancer risk was observed in genetic model of SET8 rs16917496 T/C polymorphism in Asian populations (C vs. T: OR = 1.04, 95%CI = 0.88–1.23, P = 0.63%; TC vs. TT: OR = 1.17, 95%CI = 0.96–1.24, P = 0.11%; CC vs. TT: OR = 0.90, 95%CI = 0.60–1.37, P = 0.63; TC+CC vs. TT: OR = 1.11, 95%CI = 0.90–1.38, P = 0.33; CC vs. TT+TC: OR = 0.92, 95%CI = 0.65–1.30, P = 0.63). Furthermore, similar associations were found in the subgroup analysis of race diversity, control design, genotyping methods, and different cancer types. In summary, our meta-analysis indicated that the SET8 rs16917496 T/C polymorphism may not play a critical role in cancer development in Asian populations.
