Management of Older Adults with Locally Advanced Head and Neck Cancer. Cancers (Basel) 2022; 14:cancers14112809. [PMID: 35681789 PMCID: PMC9179912 DOI: 10.3390/cancers14112809] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Revised: 05/29/2022] [Accepted: 06/01/2022] [Indexed: 02/01/2023] Open
Abstract
Simple Summary Approximately one third of patients with head and neck cancer are older adults. The number of older adults with head and neck cancer continues to rise especially as life expectancy increases. However, this population remains significantly underrepresented in clinical trials. Due to this, there is no clear consensus regarding the optimal treatment for older adults with head and neck cancer. In general, older adults are a complex cohort due to variations in functional and performance status, medical comorbidities, and medication management. Treatment for head and neck cancer involves surgery, radiation therapy, systemic therapy, or a combination. These treatments are highly demanding. Additionally, they are associated with toxicity which can be especially difficult for older adults to tolerate. This may lead to treatment interruptions and compromised outcomes. In order to understand the optimal treatment for older adults with head and neck cancer, novel predictive scores are being developed. Additionally, ongoing clinical trials are investigating less intensive treatments for older adults. This review provides an overview of current clinical data, treatment considerations, and future areas of investigation for older adults with head and neck cancer. Abstract Thirty percent of patients with head and neck squamous cell carcinoma (HNSCC) are at least 70 years of age. This number continues to rise as life expectancy continues to increase. Still, older adults with HNSCC remain underrepresented in clinical trials, resulting in ambiguity on optimal management. Older adults are a complex patient population, often requiring increased support due to issues relating to functional and performance status, medical comorbidities, and medication management. Furthermore, in older adults with HNSCC, many of these conditions are independently associated with increased toxicity and worse outcomes. Toxicity in the older adult remains difficult to predict and to understand, and as treatment decisions are based on treatment tolerability, it is essential to understand the toxicities and how to minimize them. Novel predictive scores are being developed specifically for older adults with HNSCC to understand toxicity and to assist in personalized treatment decisions. There are clinical trials presently underway that are investigating shortened radiation courses and novel, less toxic systemic treatments in this population. In the forthcoming sections, we provide a detailed overview of the clinical data, treatment paradigms, and considerations in this population. This review provides a comprehensive overview of existing clinical data and clinical considerations in the older adult head and neck cancer population. Additionally, we provide a detailed overview of pertinent current and ongoing clinical trials, as well as future areas for investigation.

Abstract
Objective To examine referral pattern, the timing of diagnostic/staging processes, and treatment initiation for new head and neck cancer patients in a community setting. Methods Patients with a newly diagnosed previously untreated diagnosis of head neck cancer managed at Asplundh Cancer Pavilion/Abington Memorial Hospital from October 2018 to March 2020. Source of referral and preceding workup were examined as well as intervals between initial head and neck consult and various timepoints of treatment initiation. Results One hundred and five patients were included in the study. The primary referral sources were external general otolaryngology (56.3%). Oral surgery and dermatology obtained tissue biopsy approximately 80% of the time before referral. The average time from the ordering of initial staging positron emission tomography/computed tomography to finalized results was 14 days (range: 10-25 days). Patients referred from dermatology and oral surgery were more likely to require single modality care, namely definitive surgical management. Time to treatment initiation average was 37 days (range: 29-41 days). Patients with longer treatment times noted significantly higher times to both radiation and medical oncology consults (48.42 vs. 18.13 days; P < 0.001). Conclusions No notable differences in treatment initiation times were identified based on referral source or extent of workup performed before head/neck surgery consult. It appears the largest opportunities for improvement in terms of reducing overall treatment length exist in the optimization of radiation initiation time.

Abstract
Treatment of locally advanced head and neck carcinoma not amenable for surgical resection or resected with high-risk features is usually based on (chemo-)radiation treatment. Oral mucositis represents one of the main side effects of (chemo-)radiation, with an important impact on quality of life and causing approximately 20% of early interruption of treatment, leading to a suboptimal dose administered. Treatment and prevention of oral mucositis have a central role in the therapeutic pathways of head and neck cancer patients but remains quite challenging. Although extensive research is conducted to identify interventions for the management of mucositis, very few interventions had sufficient evidence to generate an international expert consensus. This may be partially explained by confounding factors that could influence the development and assessment of oral mucositis. Little is known about the confounding factors of oral mucositis, which, if not well balanced in an experimental study, could lead to non-solid results. The current paper aims to review the main oral mucositis confounding factors related to head and neck cancer patients.

Abstract
Importance When patient populations in randomized clinical trials deviate too much from the general population, it undermines the relevance for daily practice. Objective To investigate if patients with head and neck cancer in randomized clinical trials are representative of the clinically treated population. Evidence Review A systematic literature search was performed for randomized clinical trials on head and neck cancer evaluating an intervention to improve outcome with total sample size of 100 patients or greater and published between 2009 and 2019. Outcome measures were age, performance status, and recruitment rate. National cancer registries provided reference data. Databases that were searched included MEDLINE and Epub Ahead of Print; Embase; Cochrane Central Register of Controlled Trials; and ClinicalTrials.gov. Abstracts of search results were retrieved to assess selection criteria by 2 reviewers independently. After the selection procedure was completed by both reviewers, the results were compared and reviewed once more to reach consensus. Full articles were downloaded to retrieve general study information and outcome data. Findings A total of 16 927 publications were identified, resulting in 87 compliant randomized clinical trials with a total of 34 241 patients. Half of the trials included all major head and neck sites, and one-third were exclusively for nasopharynx cancers. The experimental intervention was systemic treatment in 47 (54%) studies, radiotherapy in 23 (26%), and other in 17 (20%). Median sample size was 332, and median duration of accrual was 4.6 years. Median accrual per center per year for head and neck and nasopharynx trials was 5.4 and 39.7 patients, respectively. Median age of patients in head and neck trials was 57 years, which was 7 years younger than in cancer registries. More than 70% of patients had a World Health Organization performance score of 0 to 1 or a Karnofsky performance status of 90 to 100. Conclusions and Relevance In this systematic review, patients in head and neck randomized clinical trials had a very good performance status, and half of them were younger than 57 years, while half of the clinical population was older than 64 years. In more than 50% of the head and neck trials, the yearly accrual per center was less than 6 patients, suggesting overly restrictive recruitment. Critical appraisal of trial population characteristics is recommended before results are implemented in clinical guidelines and general practice.

Similar long-term swallowing outcomes for accelerated, mildly-hypofractionated radiotherapy compared to conventional fractionation in oropharynx cancer: a multi-centre study. Radiother Oncol 2022; 172:111-117. [PMID: 35595173 DOI: 10.1016/j.radonc.2022.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND AND PURPOSE There is renewed interest in hypofractionated radiotherapy, but limited data and a lack of consensus to support use for head and neck cancer. In this multicentre analysis we compared outcomes for patients with oropharynx squamous cell carcinoma (OPSCC) treated with conventional and accelerated, mildly hypofractionated radiotherapy without chemotherapy. MATERIALS AND METHODS A multi-centre, observational study of consecutive OPSCCs treated between 2015 and 2018. Patients underwent curative-intent radiotherapy (oropharynx and bilateral neck) using conventionally fractionated (70 Gy in 35 fractions over 7 weeks, n = 97) or accelerated, mildly hypofractionated (65-66 Gy in 30 fractions over 6 weeks, n = 136) radiotherapy without chemotherapy. Locoregional control (LRC) and overall survival (OS) were compared. Patients alive and cancer-free at a minimum of 2 years post-radiotherapy (n = 151, 65%) were sent an MD Anderson Dysphagia Inventory (MDADI) questionnaire to assess swallow function. RESULTS LRC and OS were similar across schedules (p = 0.78 and 0.95 respectively, log-rank test). Enteral feeding rates during radiotherapy appeared higher in the 7-week group though this did not reach statistical significance (59% vs 48%, p = 0.08). Feeding rates were similar at 1 year post radiotherapy for both groups (10% vs 6%, p = 0.27). 107 patients returned MDADI questionnaires (71%); there were no differences between the 6- and 7-week groups for median global (60.0 vs 60.0, p = 0.99) and composite (65.8 vs 64.2, p = 0.44) MDADI scores. CONCLUSION Patients with OPSCC treated with radiotherapy alone have similar swallowing outcomes, LRC and OS following accelerated, mild hypofractionation and standard fractionation schedules, supporting its use as a standard-of-care option for patients unsuitable for concurrent chemotherapy.

Abstract
PURPOSE A two-stage genome-wide association study was carried out in head and neck cancer (HNC) patients aiming to identify genetic variants associated with either specific radiotherapy-induced (RT) toxicity endpoints or a general proneness to develop toxicity after RT. MATERIALS AND METHODS The analysis included 1780 HNC patients treated with primary RT for laryngeal or oro/hypopharyngeal cancers. In a non-hypothesis-driven explorative discovery study, associations were tested in 1183 patients treated within The Danish Head and Neck Cancer Group. Significant associations were later tested in an independent Dutch cohort of 597 HNC patients and if replicated, summary data obtained from discovery and replication studies were meta-analysed. Further validation of significantly replicated findings was pursued in an Asian cohort of 235 HNC patients with nasopharynx as the primary tumour site. RESULTS We found and replicated a significant association between a locus on chromosome 5 and mucositis with a pooled OR for rs1131769*C in meta-analysis = 1.95 (95% CI 1.48-2.41; ppooled = 4.34 × 10-16). CONCLUSION This first exploratory GWAS in European cohorts of HNC patients identified and replicated a risk locus for mucositis. A larger Meta-GWAS to identify further risk variants for RT-induced toxicity in HNC patients is warranted.

ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:440. [PMID: 35571433 PMCID: PMC9096410 DOI: 10.21037/atm-21-5288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 01/14/2022] [Indexed: 11/06/2022]
Abstract
Background The optimal treatment strategy for patients with early glottic (T1-2N0M0) squamous cancer remains unclear. Methods A retrospective population-based analysis was performed using the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was used to balance treatment arms, and Cox regression analysis was used to determine prognostic factors for survival. Kaplan-Meier analysis, log-rank tests, and competing risk analysis were used to compare survival outcomes between treatment modalities (surgery vs. radiotherapy). Results Among the 3,994 eligible patients in this study, surgery was associated with improved cancer-specific survival (CSS) and overall survival (OS) compared with radiotherapy (log-rank test, P<0.05). This survival trend favoring surgery was consistent in the T1a, well/moderately differentiated grade, male, and all age subgroups. However, after the baseline characteristics were balanced with PSM, the survival outcomes (CSS and OS) did not differ significantly between the surgery and radiotherapy groups. Interestingly, surgery was associated with a 39% reduced risk of cancer-related death compared with radiotherapy in patients aged ≥70 years (hazard ratio 0.61; 95% CI: 0.43-0.87; P=0.006). However, this survival trend favoring surgery was not observed in younger patients (age <70 years), T stage subgroups, male or female subgroups, or in any of the pathological grade subgroups. Conclusions In patients with early glottic squamous cell carcinoma undergoing surgery or radiotherapy, there is no sufficient evidence favoring one method over another in terms of survival. However, surgery is recommended in patients aged ≥70 years because, in this group, it was associated with improved survival outcomes compared with radiotherapy.

Abstract
PURPOSE Conventional photosensitizers for photodynamic therapy (PDT) typically have wide tissue distribution and poor water solubility. A hyaluronic acid (HA) polymeric nanoparticle with specific lymphatic uptake and highly water solubility was developed to deliver pyropheophorbide-a (PPa) for locally advanced head and neck squamous cell carcinoma (HNSCC) treatment. METHODS AND RESULTS PPa was chemically conjugated to the HA polymeric nanoparticle via an adipic acid dihydrazide (ADH) linker. The conjugates were injected subcutaneously in a region near the tumor. Near-infrared (NIR) imaging was used to monitor distribution, and diode laser was used to activate PPa. The singlet oxygen generation efficiency of PPa was not affected by conjugation to HA nanoparticles at a PPa loading degree of 1.89 w.t.%. HA-ADH-PPa inhibited human HNSCC MDA-1986 cell growth only when photo-irradiation was applied. After HA-ADH-PPa treatment and radiation, NU/NU mice bearing human HNSCC MDA-1986 tumors showed reduced tumor growth and significantly enhanced survival time compared with an untreated group (p < 0.05). CONCLUSIONS These results demonstrate that HA-ADH-PPa could be useful for in vivo locoregional photodynamic therapy of HNSCC.

Abstract
OBJECTIVES The number of elderly head-and-neck squamous cell carcinoma (HNSCC) patients is increasing, and clinical trials defining the standard of care either excluded or underrepresented elderly patients. This leaves physicians with a challenging and highly individual treatment decision largely lacking clinical evidence. METHODS A tri-national patterns-of-care survey was sent to all members of the German (DEGRO), Austrian (ÖGRO), and Swiss (SRO/SSRO) national societies of radiation oncology. The online questionnaire consisted of 27 questions on the treatment of elderly HNSCC patients, including 6 case-based questions. Frequency distributions and subgroup comparisons were calculated using SPSS statistics software. RESULTS A total of 132 answers were collected, including 46(35%) form universities, 52(39%) from non-university-hospitals and 34(26%) from private practices. 83(63%) treat 1-5 and 42(32%) >5 elderly HNSCC patients per month. Target volumes are defined analog current guidelines by 65(50%) of responders and altered based on age/comorbidities or tumor stage by 36(28%) and 28(22%), respectively. Chemotherapy is routinely administered by 108(84%) if indicated, with weekly 40mg/m2 of cisplatin being the favored regimen by 68(53%) in the definitive situation and 60(47%) in the adjuvant setting. Hypofractionation and hyperfractionation/acceleration are used by 26(20%) and 11(9%), respectively. Only 7(5%) clinicians routinely recommend inpatient treatment for elderly HNSCC patients. In a typical definitive patient case, 73(63%) responders recommended chemoradiation with bilateral elective node irradiation analog current guidelines. In an adjuvant example case recommendations regarding elective volume and chemotherapy were heterogeneous. Differences between responders' institutions concern the frequency of PET-CT in staging, preventive port-catheter and PEG implantation, the choice of chemotherapy regimens and the use of alternative fractionations. CONCLUSION Treatment of elderly HNSCC-patients in the German-speaking countries mainly follows guidelines established for younger patients. Algorithms for patient stratification and treatment de-escalation for "unfit" elderly patients are needed.

Abstract
Head and neck squamous cell carcinomas (HNSCC) constitute the sixth most common malignancy worldwide, with approximately 25-40% of the diagnosed patients older than 70 years. HNSCC patients are often frail and frequently have multiple comorbidities due to their unhealthy lifestyle, and evidence suggests that older patients may receive less aggressive and suboptimal treatment than younger patients with the same disease status. The aim of this review is to depict and summarize the evidence regarding the different strategies that can be used in the clinical management of elderly HNSCC patients. Key references were derived from a PubMed query. Hand searching and clinicaltrials.gov were also used. This paper contains a narrative report and a critical discussion of clinical approaches in the context of elderly HNSCC.

Abstract
INTRODUCTION Radiation dose-escalation for head and neck cancer (HNC) patients aiming to improve cure rates is challenging due to the increased risk of unacceptable treatment-induced toxicities. With "Proton Image-guided Radiation Assignment for Therapeutic Escalation via Selection of locally advanced head and neck cancer patients" (PIRATES), we present a novel treatment approach that is designed to facilitate dose-escalation while minimizing the risk of dose-limiting toxicities for locally advanced HPV-negative HNC patients. The aim of this Phase I trial is to assess the safety & feasibility of PIRATES approach. METHODS The PIRATES protocol employs a multi-faceted dose-escalation approach to minimize the risk of dose-limiting toxicities (DLTs): 1) sparing surrounding normal tissue from extraneous dose with intensity-modulated proton therapy, 2) mid-treatment hybrid hyper-fractionation for radiobiologic normal tissue sparing; 3) Magnetic Resonance Imaging (MRI) guided mid-treatment boost volume adaptation, and 4) iso-effective restricted organ-at-risk dosing to mucosa and bone tissues.The time-to-event Bayesian optimal interval (TITE-BOIN) design is employed to address the challenge of the long DLT window of 6 months and find the maximum tolerated dose. The primary endpoint is unacceptable radiation-induced toxicities (Grade 4, mucositis, dermatitis, or Grade 3 myelopathy, osteoradionecrosis) occurring within 6 months following radiotherapy. The second endpoint is any grade 3 toxicity occurring in 3-6 months after radiation. DISCUSSION The PIRATES dose-escalation approach is designed to provide a safe avenue to intensify local treatment for HNC patients for whom therapy with conventional radiation dose levels is likely to fail. PIRATES aims to minimize the radiation damage to the tissue surrounding the tumor volume with the combination of proton therapy and adaptive radiotherapy and within the high dose tumor volume with hybrid hyper-fractionation and not boosting mucosal and bone tissues. Ultimately, if successful, PIRATES has the potential to safety increase local control rates in HNC patients with high loco-regional failure risk.Trial registration: ClinicalTrials.gov ID: NCT04870840; Registration date: May 4, 2021.Netherlands Trial Register ID: NL9603; Registration date: July 15, 2021.

Abstract
Background Radio-chemotherapy with CDDP is the standard for H&N squamous cell cancer. CDDP 100 mg/m2/q3 is the standard; alternative schedules are used to reduce toxicity, mostly 40 mg/m2/q1.
Methods Patients were treated from 1/2010 to 1/2017 in two Radiation Oncology Centres. Propensity score analysis (PS) was retrospectively used to compare these two schedules. Results Patients analyzed were 166. Most (114/166) had 1w-CDDP while 52 had 3w-CDDP. In the 3w-CDDP group, patients were younger, with better performance status, smaller disease extent and a more common nodal involvement than in the 1w-CDDP. Acute toxicity was similar in the groups. Treatment compliance was lower in the w-CCDP. Overall survival before PS was better for female, for oropharyngeal disease and for 3w-CDDP group. After PS, survival was not related to the CDDP schedule. Conclusions 3w-CDDP remains the standard for fit patients, weekly schedule could be safely used in selected patients.

Abstract
Despite extensive use of radiotherapy in nasopharyngeal carcinoma (NPC) treatment because of its high radiosensitivity, there have been huge challenges in further improving therapeutic effect, meanwhile obviously reducing radiation damage. To this end, synergistic chemoradiotherapy has emerged as a potential strategy for highly effective NPC therapy. Here, we developed RGD-targeted platinum-based nanoparticles (RGD-PtNPs, denoted as RPNs) to achieve targeted chemoradiotherapy for NPC. Such nanoparticles consist of an RGD-conjugated shell and a cis-platinum (CDDP) crosslinking core. Taking advantage of RGD, the RPNs may effectively accumulate in tumor, penetrate into tumor tissues and be taken by cancer cells, giving rise to a high delivery efficiency of CDDP. When they are fully enriched in tumor sites, the CDDP loaded RPNs can act as radiotherapy sensitizer and chemotherapy agents. By means of X-ray-promoted tumor cell uptake of nanoparticle and CDDP-induced cell cycle arrest in radiation-sensitive G2/M phases, RPNs may offer remarkable therapeutic outcome in the synergistic chemoradiotherapy for NPC.

Abstract
INTRODUCTION Individual patient data (IPD) present particular advantages in network meta-analysis (NMA) because interactions may lead an aggregated data (AD)-based model to wrong a treatment effect (TE) estimation. However, fewer works have been conducted for IPD with time-to-event contrary to binary outcomes. We aimed to develop a general frequentist one-step model for evaluating TE in the presence of interaction in a three-node NMA for time-to-event data. METHODS One-step, frequentist, IPD-based Cox and Poisson generalized linear mixed models were proposed. We simulated a three-node network with or without a closed loop with (1) no interaction, (2) covariate-treatment interaction, and (3) covariate distribution heterogeneity and covariate-treatment interaction. These models were applied to the NMA (Meta-analyses of Chemotherapy in Head and Neck Cancer [MACH-NC] and Radiotherapy in Carcinomas of Head and Neck [MARCH]), which compared the addition of chemotherapy or modified radiotherapy (mRT) to loco-regional treatment with two direct comparisons. AD-based (contrast and meta-regression) models were used as reference. RESULTS In the simulated study, no IPD models failed to converge. IPD-based models performed well in all scenarios and configurations with small bias. There were few variations across different scenarios. In contrast, AD-based models performed well when there were no interactions, but demonstrated some bias when interaction existed and a larger one when the modifier was not distributed evenly. While meta-regression performed better than contrast-based only, it demonstrated a large variability in estimated TE. In the real data example, Cox and Poisson IPD-based models gave similar estimations of the model parameters. Interaction decomposition permitted by IPD explained the ecological bias observed in the meta-regression. CONCLUSION The proposed general one-step frequentist Cox and Poisson models had small bias in the evaluation of a three-node network with interactions. They performed as well or better than AD-based models and should also be undertaken whenever possible.

Bollen H, van der Veen J, Laenen A, Nuyts S. Recurrence Patterns After IMRT/VMAT in Head and Neck Cancer. Front Oncol 2021; 11:720052. [PMID: 34604056 PMCID: PMC8483718 DOI: 10.3389/fonc.2021.720052] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 08/30/2021] [Indexed: 01/04/2023] Open
Abstract
Purpose Intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT), two advanced modes of high-precision radiotherapy (RT), have become standard of care in the treatment of head and neck cancer. The development in RT techniques has markedly increased the complexity of target volume definition and accurate treatment delivery. The aim of this study was to indirectly investigate the quality of current TV delineation and RT delivery by analyzing the patterns of treatment failure for head and neck cancer patients in our high-volume RT center. Methods Between 2004 and 2014, 385 patients with pharyngeal, laryngeal, and oral cavity tumors were curatively treated with primary RT (IMRT/VMAT). We retrospectively investigated locoregional recurrences (LRR), distant metastases (DM), and overall survival (OS). Results Median follow-up was 6.4 years (IQR 4.7–8.3 years) during which time 122 patients (31.7%) developed LRR (22.1%) and DM (17.7%). The estimated 2- and 5-year locoregional control was 78.2% (95% CI 73.3, 82.3) and 74.2% (95% CI 69.0, 78.8). One patient developed a local recurrence outside the high-dose volume and five patients developed a regional recurrence outside the high-dose volume. Four patients (1.0%) suffered a recurrence in the electively irradiated neck and two patients had a recurrence outside the electively irradiated neck. No marginal failures were observed. The estimated 2- and 5-year DM-free survival rates were 83.3% (95% CI 78.9, 86.9) and 80.0% (95% CI 75.2, 84.0). The estimated 2- and 5-year OS rates were 73.6% (95% CI 68.9, 77.8) and 52. 6% (95% CI 47.3, 57.6). Median OS was 5.5 years (95% CI 4.5, 6.7). Conclusion Target volume definition and treatment delivery were performed accurately, as only few recurrences occurred outside the high-dose regions and no marginal failures were observed. Research on dose intensification and identification of high-risk subvolumes might decrease the risk of locoregional relapses. The results of this study may serve as reference data for comparison with future studies, such as dose escalation or proton therapy trials.

Investigation of optimum minimum segment width on VMAT plan quality and deliverability: A comprehensive dosimetric and clinical evaluation using DVH analysis. J Appl Clin Med Phys 2021; 22:29-40. [PMID: 34592787 PMCID: PMC8598144 DOI: 10.1002/acm2.13417] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 06/23/2021] [Accepted: 08/24/2021] [Indexed: 12/15/2022] Open
Abstract
Purpose Minimum segment width (MSW) plays a fundamental role in the shaping of optimized apertures and creation of segments of varying sizes and shapes in complex radiotherapy treatment plans. The purpose of this work was to study the effect of MSW on dose distribution in patients planned with VMAT for various treatment sites using dose volume histogram (DVH) analysis. Materials and methods For the validation of optimum MSW, 125 clinical treatment plans were evaluated. Five groups were identified (brain, head and neck, thorax, pelvis, and extremity), and five cases were chosen from each group. For each case, five plans were created with different MSW (0.5, 0.8, 1.0, 1.25, and 1.5 cm). The quality of treatment plans created using different MSW were compared using dosimetric indicators such as target coverage (D98—dose to 98% of the planning target volume (PTV), maximum dose (D2—maximum dose to 2% of the PTV), monitor units (MU), and DVH parameters related to organs at risk (OAR). The effect of the MSW on delivery accuracy was quantitatively analyzed using the measured fluence utilizing ionization chamber‐based transmission detector and model‐based dose verification system. Traditional global gamma analysis (2%, 2 mm) and dose volume information was gathered for the PTV and organs at risk and compared for different MSWs. Results A total of 125 plans were created and compared across five groups. In terms of treatment plan quality, the plans using MSW of 0.5 cm was found to be superior in all groups. PTV coverage (D98) decreased significantly (p < 0.05) as the MSW increased. Similarly, the maximum dose (D2) was found to be increased significantly (p < 0.05) as the MSW increased from 0.5 cm, with MSW of 1.5 cm being the least in terms of plan quality for both PTVs and OARs. In terms of plan deliverability using DVH analysis, treatment planning system (TPS) compared to measured fluence, VMAT plans produced with MSW of 0.5 cm showed a better dosimetric index and a smaller deviation for both PTVs and OARs. The deliverability of the plans deteriorated as the MSW increased. Conclusion Dose volume histogram (DVH) analysis demonstrated that treatment plans with minimal MSW showed better plan quality and deliverability and provided clinical relevance as compared to gamma index analysis.

Treatment Outcomes of Head and Neck Cancer Patients in the Elderly Receiving Different Chemoradiation Combinations: A Single-Center Experience. Oncol Res Treat 2021; 44:521-529. [PMID: 34515190 DOI: 10.1159/000518548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 07/16/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVES This study aimed to assess the effect of definitive or adjuvant concurrent chemoradiation (CRT) among elderly patients with locally advanced head and neck squamous cell carcinoma (LA HNSCC). MATERIALS AND METHODS We retrospectively analyzed 150 elderly LA HNSCC patients (age ≥70) at a single institution. Demographics, disease control outcomes, and toxicities with different chemotherapy regimens were reviewed. The Kaplan-Meier method was used to estimate progression-free survival (PFS) and overall survival (OS) estimates. RESULTS Median age at diagnosis was 74 years (range 70-88). Of the cohort, 98 (65.3%) patients received definitive and 52 (34.7%) received adjuvant CRT; 44 (29.3%) patients received weekly carboplatin and paclitaxel, 43 (28.7%) weekly cetuximab, 33 (22%) weekly carboplatin, and 30 (20%) weekly cisplatin. The OS at 2 years was 70% (95% confidence interval [CI]: 63-79%), and PFS at 2 years was 61% (95% CI: 53-70%). There was no significant difference in OS or PFS between definitive and adjuvant CRT (p = 0.867 and p = 0.475, respectively). Type of chemotherapy regimen (single-agent carboplatin vs. others) (95% CI: 1.1-3.9; p = 0.009) was a key prognostic factor in predicting OS in multivariable analysis. Concurrent use of cetuximab was associated with increased risk of PEG tube dependence at 6 months (p < 0.001). CONCLUSIONS Management of LA HNSCC in the elderly is a challenging scenario. Our study shows that CRT is a feasible treatment modality for elderly patients with LA HNSCC. We recommend CRT with weekly cisplatin or weekly carboplatin and paclitaxel. A chemotherapy regimen should be carefully selected in this difficult to treat population.

Efficacy and safety of systemic treatments for patients with recurrent/metastatic head and neck squamous cell carcinoma: A systematic review and network meta-analysis. Pharmacol Res 2021; 173:105866. [PMID: 34474103 DOI: 10.1016/j.phrs.2021.105866] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 08/17/2021] [Accepted: 08/28/2021] [Indexed: 12/24/2022]
Abstract
A variety of systemic chemotherapy regimens have been used for recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). However, most guidelines have been derived from a single clinical trial, and no studies have comprehensively compared their efficacy and safety. We systematically searched PubMed, Embase, Web of Science, and Cochrane Library databases. Eligible studies reported overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and ≥ 3 adverse events rate (AEs). Eighteen eligible trials involving 4930 patients and 15 treatment regimens were included. The results suggest that patients with R/M HNSCC exhibit better tumor response with the cetuximab/platinum/5-FU, pembrolizumab/platinum/5-FU or pembrolizumab alone, accompanied by a low AE rate. Nivolumab also showed better efficacy than other single agents. Immunotherapy has achieved better efficacy.

Abstract
BACKGROUND Radical (chemo)radiotherapy offers potentially curative treatment for patients with locally advanced laryngeal or hypopharyngeal cancer. We aimed to show that dose-escalated intensity-modulated radiotherapy (DE-IMRT) improved locoregional control. METHODS We performed a phase III open-label randomised controlled trial in patients with laryngeal or hypopharyngeal cancer (AJCC III-IVa/b, TNM 7). Patients were randomised (1:1) to DE-IMRT or standard dose IMRT (ST-IMRT) using a minimisation algorithm, balancing for centre, tumour site, nodal status and chemotherapy use. DE-IMRT was 67.2 gray (Gy) in 28 fractions (f) to the primary tumour and 56Gy/28f to at-risk nodes; ST-IMRT was 65Gy/30f to primary tumour and 54Gy/30f to at-risk nodes. Suitable patients received 2 cycles of concomitant cisplatin and up to 3 cycles of platinum-based induction chemotherapy. The primary end-point was time to locoregional failure analysed by intention-to-treat analysis using competing risk methodology. FINDINGS Between February 2011 and October 2015, 276 patients (138 ST-IMRT; 138 DE-IMRT) were randomised. A preplanned interim futility analysis met the criterion for early closure. After a median follow-up of 47.9 months (interquartile range 37.5-60.5), there were locoregional failures in 38 of 138 (27.5%) ST-IMRT patients and 42 of 138 (30.4%) DE-IMRT patients; an adjusted subhazard ratio of 1.16 (95% confidence interval: 0.74-1.83, p = 0.519) indicated no evidence of benefit with DE-IMRT. Acute grade 2 pharyngeal mucositis was reported more frequently with DE-IMRT than with ST-IMRT (42% vs. 32%). No differences in grade ≥3 acute or late toxicity rates were seen. CONCLUSION DE-IMRT did not improve locoregional control in patients with laryngeal or hypopharyngeal cancer. The trial is registered: ISRCTN01483375.

Abstract
Background Both patient-specific dose recalculation and γ passing rate analysis are important for the quality assurance (QA) of intensity modulated radiotherapy (IMRT) plans. The aim of this study was to analyse the correlation between the γ passing rates and the volumes of air cavities (Vair) and bony structures (Vbone) in target volume of head and neck cancer. Methods Twenty nasopharyngeal carcinoma and twenty nasal natural killer T-cell lymphoma patients were enrolled in this study. Nine-field sliding window IMRT plans were produced and the dose distributions were calculated by anisotropic analytical algorithm (AAA), Acuros XB algorithm (AXB) and SciMoCa based on the Monte Carlo (MC) technique. The dose distributions and γ passing rates of the targets, organs at risk, air cavities and bony structures were compared among the different algorithms. Results The γ values obtained with AAA and AXB were 95.6 ± 1.9% and 96.2 ± 1.7%, respectively, with 3%/2 mm criteria (p > 0.05). There were significant differences (p < 0.05) in the γ values between AAA and AXB in the air cavities (86.6 ± 9.4% vs. 98.0 ± 1.7%) and bony structures (82.7 ± 13.5% vs. 99.0 ± 1.7%). Using AAA, the γ values were proportional to the natural logarithm of Vair (R2 = 0.674) and inversely proportional to the natural logarithm of Vbone (R2 = 0.816). When the Vair in the targets was smaller than approximately 80 cc or the Vbone in the targets was larger than approximately 6 cc, the γ values of AAA were below 95%. Using AXB, no significant relationship was found between the γ values and Vair or Vbone. Conclusion In clinical head and neck IMRT QA, greater attention should be paid to the effect of Vair and Vbone in the targets on the γ passing rates when using different dose calculation algorithms.

Abstract
Background Tobacco and alcohol use are risk factors for Squamous Cell Carcinoma of the Head and Neck (SCCHN); however, there is growing recognition of HPV as a risk factor for SCCHN. HPV‐related SCCHN is thought to affect mostly middle‐aged individuals but as the US population ages, it is important to evaluate the change in incidence of HPV‐ and non‐HPV‐related SCCHN in individuals who are ≥65 years old. Methods This was a retrospective study using data from a population‐based cancer registry (SEER) to identify individuals ≥65 years old diagnosed with SCCHN between 2000 and 2016 also stratified by sex, race, and birth cohort. The subgroups of HPV‐associated and non‐HPV associated sites were analyzed independently. The incidence per year was calculated and joinpoint detection was used to identity significant changes in incidence trends and annual percent change (APC). Results For HPV‐associated sites from 2000 to 2016, there was an average annual rate of 10.8 per 100,000 individuals with an APC of 2.92% (p = <0.05). For HPV‐ and non‐HPV‐related SCCHN males had a higher annual rate compared to females, 54.5 versus 18.0 in non‐HPV‐related and 19.1 versus 4.4 in HPV‐related sites. For non‐HPV‐related sites there was a decrease in APC across all stratified groups. For HPV‐related sites there was an increase in APC across all stratified groups, especially males (APC 8.82% 2006–2016 p < 0.05) and White individuals (APC 8.19% 2006–2016 p < 0.05). When stratified by birth cohort, HPV‐related SCCHN sites had a higher APC in ages 65–69 (8.38% p < 0.05) and 70–74 (8.54% p < 0.05). Conclusion Among the population ≥65 years old from 2000 to 2016, the incidence rate for HPV‐related SCCHN sites has increased across all stratified groups, especially in White individuals, males, and age groups 65–74. The incidence rate for non‐HPV‐related sites has decreased across all stratified groups during this time.

Use of Supraclavicular Flap by End to Side Technique in Pharyngeal SCC: A Case Report and Review of Literature. Case Rep Otolaryngol 2021; 2021:6619916. [PMID: 34336336 PMCID: PMC8298143 DOI: 10.1155/2021/6619916] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 03/19/2021] [Accepted: 07/09/2021] [Indexed: 11/17/2022] Open
Abstract
Objectives In recent years, conservation laryngeal surgeries, including partial pharyngectomy, have been introduced as an alternative procedure for selected cases of hypopharyngeal squamous cell carcinoma (HSCC). Reconstruction of these defects presents a considerable challenge for the surgeon after partial pharyngectomy due to its circumferential nature. In this case report, we represent the innovative "End to side" technique to reconstruct hypopharyngeal defect using the rolled supraclavicular flap after laryngeal-preserving partial pharyngectomy. Methods and Results A 70-year-old female presented with a history of progressive dysphagia and odynophagia. The evaluations revealed a T3N0M0 SCC of pyriform sinus. The mass was successfully resected through partial pharyngectomy, and the hypopharyngeal defect reconstruction was achieved using the rolled supraclavicular flap via the "End to side" technique. The patient was discharged after decannulation on day 10. The 3-week barium swallow was performed with no evidence of anastomotic leakage, and the oral feeding was started after NG tube removal. At week 5, complete movement of the true vocal cord on the one side and good phonation and deglutition was observed. There was no evidence of recurrence after 1 year. Conclusions Laryngeal-preserving partial pharyngectomy and hypopharyngeal reconstruction with the rolled supraclavicular flap via the "End to side" technique could lead to good oncological and functional outcomes in selected cases of pyriform sinus.

Abstract
Head and neck cancer (HNC) is the sixth most common malignancy worldwide; head and neck squamous cell carcinoma (HNSCC) account for the most cases of HNC. Past smoking and alcohol consumption are common risk factors of HNSCC; however, an increasing number of cases associated with human papillomavirus (HPV) infection have been reported in recent years. The treatment of HNSCC is integrated and multimodal including traditional surgery, radiotherapy, chemotherapy, and targeted therapy. Since pembrolizumab was approved in 2016, an increasing number of studies have focused on immunotherapy. However, not all of HNSCC patients have a better outcome on immunotherapy. Immunotherapy has been reported to be more effective in HPV-positive patients, but its molecular mechanism is still unclear. Some researchers have proposed that the high proportion of infiltrating immune cells in HPV-positive tumors and the difference in immune checkpoint expression level may be the reasons for their better response. As a result, a series of individualized immunotherapy trials have also been conducted in HPV-positive patients. This paper summarizes the current status of HNSCC immunotherapy, individualized immunotherapy in HPV-positive patients, and immune differences in HPV-positive tumors to provide new insights into HNSCC immunotherapy and try to identify patients who may benefit from immunotherapy.

NMR-Based Metabolomics in Investigation of the Radiation Induced Changes in Blood Serum of Head and Neck Cancer Patients and Its Correlation with the Tissue Volumes Exposed to the Particulate Doses. Int J Mol Sci 2021; 22:ijms22126310. [PMID: 34208417 PMCID: PMC8231285 DOI: 10.3390/ijms22126310] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 06/08/2021] [Accepted: 06/08/2021] [Indexed: 02/07/2023] Open
Abstract
In the present study, we analyze the nuclear magnetic resonance (NMR) blood serum metabolic profiles of 106 head and neck squamous cell carcinoma (HNSCC) patients during radio (RT) and concurrent radio-chemotherapy (CHRT). Four different fractionation schemes were compared. The blood samples were collected weekly, from the day before the treatment until the last week of CHRT/RT. The NMR spectra were acquired on A Bruker 400 MHz spectrometer at 310 K and analyzed using multivariate methods. Seven metabolites were found significantly to be altered solely by radiotherapy: N-acetyl-glycoprotein (NAG), N-acetylcysteine, glycerol, glycolate and the lipids at 0.9, 1.3 and 3.2 ppm. The NMR results were correlated with the tissue volumes receiving a particular dose of radiation. The influence of the irradiated volume on the metabolic profile is weak and mainly limited to sparse correlations with the inflammatory markers, creatinine and the lymphocyte count in RT and the branched-chain amino-acids in CHRT. This is probably due to the optimal planning and delivery of radiotherapy improving sparing of the surrounding normal tissues and minimizing the differences between the patients (caused by the tumor location and size).

Abstract
Purpose Radiomics has already been proposed as a prognostic biomarker in head and neck cancer (HNSCC). However, its predictive power in radiotherapy has not yet been studied. Here, we investigated a local radiomics approach to distinguish between tumor sub-volumes with different levels of radiosensitivity as a possible target for radiation dose intensification. Materials and Methods Of 40 patients (n=28 training and n=12 validation) with biopsy confirmed locally recurrent HNSCC, pretreatment contrast-enhanced CT images were registered with follow-up PET/CT imaging allowing identification of controlled (GTVcontrol) vs non-controlled (GTVrec) tumor sub-volumes on pretreatment imaging. A bi-regional model was built using radiomic features extracted from pretreatment CT in the GTVrec and GTVcontrol to differentiate between those regions. Additionally, concept of local radiomics was implemented to perform detection task. The original tumor volume was divided into sub-volumes with no prior information on the location of recurrence. Radiomic features from those sub-volumes were then used to detect recurrent sub-volumes using multivariable logistic regression. Results Radiomic features extracted from non-controlled regions differed significantly from those in controlled regions (training AUC = 0.79 CI 95% 0.66 - 0.91 and validation AUC = 0.88 CI 95% 0.72 – 1.00). Local radiomics analysis allowed efficient detection of non-controlled sub-volumes both in the training AUC = 0.66 (CI 95% 0.56 – 0.75) and validation cohort 0.70 (CI 95% 0.53 – 0.86), however performance of this model was inferior to bi-regional model. Both models indicated that sub-volumes characterized by higher heterogeneity were linked to tumor recurrence. Conclusion Local radiomics is able to detect sub-volumes with decreased radiosensitivity, associated with location of tumor recurrence in HNSCC in the pre-treatment CT imaging. This proof of concept study, indicates that local CT radiomics can be used as predictive biomarker in radiotherapy and potential target for dose intensification.

Patient-Reported Toxicity and Quality-of-Life Profiles in Patients With Head and Neck Cancer Treated With Definitive Radiation Therapy or Chemoradiation. Int J Radiat Oncol Biol Phys 2021; 111:456-467.

Abstract
PURPOSE Radiation therapy is an effective but burdensome treatment for head and neck cancer (HNC). We aimed to characterize the severity and time pattern of patient-reported symptoms and quality of life in a large cohort of patients with HNC treated with definitive radiation therapy, with or without systemic treatment. METHODS AND MATERIALS A total of 859 patients with HNC treated between 2007 and 2017 prospectively completed the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Head and Neck Cancer module (QLQ-HN35) and Core Quality of Life Questionnaire (QLQ-C30) at regular intervals during and after treatment for up to 5 years. Patients were classified into 3 subgroups: early larynx cancer, infrahyoideal cancer, and suprahyoideal cancer. Outcome scales of both questionnaires were quantified per subgroup and time point by means of average scores and the frequency distribution of categorized severity (none, mild, moderate, and severe). Time patterns and symptom severity were characterized. Toxicity profiles were compared using linear mixed model analysis. Additional toxicity profiles based on age, human papillomavirus status, treatment modality, smoking status, tumor site, and treatment period were characterized as well. RESULTS The study population consisted of 157 patients with early larynx cancer, 304 with infrahyoideal cancer, and 398 with suprahyoideal cancer. The overall questionnaire response rate was 83%. Generally, the EORTC QLQ-HN35 symptoms reported showed a clear time pattern, with increasing scores during treatment followed by a gradual recovery in the first 2 years. Distinct toxicity profiles were seen across subgroups (P < .001), with generally less severe symptom scores in the early larynx subgroup. The EORTC QLQ-C30 functioning, quality-of-life, and general symptoms reported showed a less evident time pattern and less pronounced differences in mean scores between subgroups, although differences were still significant (P < .001). Differences in mean scores were most pronounced for role functioning, appetite loss, fatigue, and pain. CONCLUSIONS We established patient-reported toxicity and quality-of-life profiles that showed different patterns for 3 subgroups of patients with HNC. These profiles provide detailed information on the severity and persistence of various symptoms as experienced by patients during and after definitive radiation therapy. These profiles can be used to inform treatment of future patients and may serve as a benchmark for future studies.

Abstract
Locally advanced Head and neck squamous cell carcinoma (SCCHN) represents a common oncologic pathology in older adults (OA). While radiotherapy represents a cornerstone in this context, it is unclear what is the optimal radiation regimen for SCCHN in the palliative setting, especially for OA. This article addresses issues related to palliative radiotherapy (PRT) in this setting with a focus on treatment modalities and toxicity. We also explore the use of quality of life and geriatric assessment in this setting. Medline, Scopus and Embase databases were queried for articles in this setting. We included studies published from January 1, 2000 through June 1, 2020, that were independently evaluated by two authors. Analyzed endpoints were progression free survival (PFS), overall survival (OS) and PRT toxicities. The meta-analysis was performed using Stata v.14. A total of 33 studies were included in this meta-analysis. The pooled median OS is 7.7 months, 2-years OS was worse for higher radiation dose (p = 0.02). The pooled median PFS was 5.4 months, PFS was influenced by EQD2 (p = 0.01), with patients receiving an EQD2 < 40 Gy that presented a poorer outcome. Regarding acute toxicities, most common pooled G3 toxicities were mucositis (7%) and dysphagia (15%). Among late toxicity, most common G3 toxicity was dysphagia in 7% of patients. Radiotherapy should be the most effective palliative treatment in symptomatic SCCHN OA. A tailored approach, guided by geriatric tools, would be indicated to choose the right therapy.

Abstract
OBJECTIVES We aimed to assess patterns of care delivered to older patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC), and to analyze the use of geriatric assessment (GA) and assessment of quality of life (QoL). MATERIALS AND METHODS Members of the head and neck cancer group and the older task force of the European Organisation for Research and Treatment of Cancer (EORTC), members the European Head and Neck Society and members of national groups in Europe were asked to complete a questionnaire about treatment delivered, use of GA, and QoL assessment in older patients with LA-HNSCC. RESULTS Investigators from 111 centers replied, including 90 (81.1%) academic centers, 16 (14.4%) community hospitals, and 5 (4.5%) private clinics. Large differences in treatment patterns were found. For instance, for oropharyngeal carcinoma, one third of the centers indicated that they treat <5% of older patients with chemoradiation, while 18 centers (16.2%) treat >40% of older patients with chemoradiation. Fourteen centers (12.6%) routinely perform GA, while 43 centers (38.7%) never do, and 39 centers (35.1%) sometimes do. QoL is assessed on a routine basis in one fifth of the centers. CONCLUSIONS Large differences exist across institutions in the patterns of care delivered to older patients with LA-HNSCC. Prospective studies are required to learn how GA can guide treatment decisions, and how QoL and treatment outcome can be improved. For that, consensus on standard of care is essential.

Abstract
Background Radiotherapy for head and neck cancer may cause various oral sequelae, such as radiation-induced mucositis. To protect healthy tissue from irradiation, intraoral devices can be used. Current tissue retraction devices (TRDs) have to be either individually manufactured at considerable cost and time expenditure or they are limited in their variability. In this context, a 3D-printed, tooth-borne TRD might further facilitate clinical use. Methods A novel approach for the manufacturing of TRDs is described and its clinical application is analysed retrospectively. The devices were virtually designed for fabrication by 3D-printing technology, enabling—in only a single printing design—caudal or bi-lateral tongue displacement, as well as stabilization of a tongue-out position. For a total of 10 patients undergoing radiotherapy of head and neck tumors, the devices were individually adapted after pre-fabrication. Technical and clinical feasibility was assessed along with patient adherence. Tissue spacing was calculated by volumetric analysis of tongue retraction. In one exemplary case, radiotherapy treatment plans before and after tissue displacement were generated and compared. The reproducibility of maxillomandibular relation at device re-positioning was quantified by repeated intraoral optical scanning in a voluntary participant. Results 3D-printing was useful for the simplification of TRD manufacture, resulting in a total patient treatment time of less than 30 min. The devices were tolerated well by all tested patients over the entire radiation treatment period. No technical complications occurred with the devices. The TRDs caused an effective spacing of the healthy adjacent tissue, e.g., the tongue. Position changes of maxillomandibular relation were limited to a mean value of 98.1 µm ± 29.4 µm root mean square deviation between initial reference and follow-up positions. Conclusions The presented method allows a resource-efficient fabrication of individualized, tooth-bourne TRDs. A high reproducibility of maxillomandibular relation was found and the first clinical experiences underline the high potential of such devices for radiotherapy in the head and neck area.

Use of the Geriatric-8 screening tool to predict prognosis and complications in older adults with head and neck cancer: A prospective, observational study. J Geriatr Oncol 2021; 12:1039-1043. [PMID: 33757718 DOI: 10.1016/j.jgo.2021.03.008] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 02/12/2021] [Accepted: 03/16/2021] [Indexed: 12/27/2022]
Abstract
OBJECTIVES To clarify the usefulness of geriatric assessment screening tools for predicting prognosis and complications in older adults with head and neck cancer (HNC). MATERIAL AND METHODS The geriatric-8 (G8) screening tool was administered to 78 older adults with HNC at their first visit to the hospital before any treatments. The ability of the G8 to predict survival was evaluated by receiver operating characteristic (ROC) curve analysis and determining the cut-off value using Youden's Index. The G8 and other factors related to prognosis (age, performance status (PS), Charlson comorbidity index, number of oral medicines (polypharmacy), the controlling nutritional status (CONUT) score for biological nutrition status, and treatment intent (curative or palliative)) were validated by Cox proportional hazards regression analysis. The survival analysis was validated in a propensity score-weighting cohort to correct for confounding factors. Correlations between these factors and complications were examined using Fishers exact test. RESULTS The G8 cut-off value for overall survival was 10.5 (area under the curve (AUC) 0.69; 95% confidence interval (CI) 0.56-0.82). In the propensity score-weighted cohort, on Cox proportional hazards regression analysis, the hazard ratio of an abnormal G8 (<11) was 3.70 [1.59-8.61 (p = 0.002)], and the hazard ratio of PS-abnormal (≥2) was 0.85 [0.09-7.60 (p = 0.88)]. Thirty-day mortality and all-complication rates were significantly higher in the G8-abnormal group. Neither major complications nor transfer to other institutions was correlated with an abnormal G8. CONCLUSION The G8 was a strong prognostic factor and a possible predictor of complications in older adults with HNC.

Cancer 2021; 127:1984-1992. [PMID: 33631040 DOI: 10.1002/cncr.33471] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 11/23/2020] [Accepted: 11/27/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is used in head and neck squamous cell carcinoma (HNSCC) for downstaging advanced disease and decreasing distant metastasis (DM). To the authors' knowledge, no study has specifically examined the impact of a delayed time to surgery (TTS) after NAC on oncologic outcomes. They thus aimed to identify a cutoff for TTS after NAC and its effect on survival indices. METHODS This was a retrospective review of all patients with HNSCC receiving NAC followed by surgery with curative intent between March 2016 and March 2019 at the MD Anderson Cancer Center. Receiver operating characteristic analysis was used to identify a cutoff for TTS, and this cutoff was used to analyze the overall survival (OS), locoregional recurrence rate, DM-free rate, and disease-free survival (DFS). A multivariate Cox regression analysis was performed. RESULTS One hundred one patients were analyzed with a median follow-up of 24.7 months. The 3-year OS and locoregional recurrence rates did not differ with a TTS ≥ 34 days. However, the 3-year DM-free rate was significantly worse (56% vs 90%; P = .001) in the group with a TTS ≥ 34 days, and the 3-year DFS was significantly lower (26% vs 64%; P = .006). In a multivariate analysis, a TTS ≥ 34 days (hazard ratio [HR], 4.92; 95% confidence interval [CI], 1.84-13.13) and extracapsular extension (HR, 3.01; 95% CI, 1.13-8.00) were significant independent predictors of a poorer DM-free rate. Weight loss > 10% (HR, 5.53; 95% CI, 1.02-30.24) was the only independent predictor for a TTS ≥ 34 days. CONCLUSIONS Emphasis should be placed on early definitive locoregional treatment after NAC, particularly in patients who do not respond to NAC. There is a need to validate these findings and establish new benchmarks for the interval between NAC and surgery.

Abstract
BACKGROUND Transoral robotic surgery is frequently described, driven by the desire to offer a less morbid alternative to chemoradiation. However, the objective evaluation of post-operative function has rarely been reported. Therefore, high-resolution manometry was used in this study to evaluate the impact of changes in peri-operative swallowing function on pharyngeal pressure events. METHODS Ten patients with various stages of oropharyngeal cancer underwent transoral surgery. High-resolution manometry and videofluoroscopic swallow studies were performed before surgery and two months afterwards. The following parameters were obtained: velopharyngeal and mesopharyngeal post-deglutitive upper oesophageal sphincter pressures, velo-meso-hypopharyngeal contractile integral, upper oesophageal sphincter relaxation pressure, and pharyngeal velocity. RESULTS There was no significant difference in pharyngeal pressure or contractile integral pre- versus post-operatively. However, pharyngeal velocity was significantly higher post-operatively than pre-operatively. CONCLUSION High-resolution manometry showed that transoral surgery in patients without pre-operative dysphagia preserved pharyngeal constriction. However, transoral surgery might produce scar formation in the pharynx, which could lead to narrowing of the pharynx.

Abstract
INTRODUCTION Favorable outcomes are observed after treatment with standard chemoradiotherapy (CRT) for Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) patients. The consistent growing interest on treatment-related toxicity burden, potentially jeopardizing survivors' quality of life, led clinicians to investigate possible de-escalation strategies. MATERIALS AND METHODS A comprehensive systematic literature search of clinical trials was performed through the EMBASE database to provide an overview of the de-escalation strategies spectrum. Additionally, hand searching and clinicaltrials.gov were also used. RESULTS Herein, we report and discuss different approaches to de-escalation of therapy, with respect to both local and systemic strategies. CONCLUSIONS Several promising de-escalation experiences have been published. However, while further evidence is awaited, no changes in the management nor deviation from the standard of care should be made outside of clinical trials.

Abstract
Radiotherapy and chemotherapy are integral parts of definitive and adjuvant therapy in the treatment of head and neck squamous cell carcinoma (HNSCC). The outcome of therapy is essentially dependent on selection and dosage of chemotherapeutical substances and on the other hand on the radiotherapeutical setting concerning fractionation, time of therapy and technical aspects. Immunotherapeutical substances have an increasing role in the therapy of HNSCC as well as particle therapy is investigated as part of radiotherapy in actual studies. Further challenges relate to treatment of HPV-induced tumors with regard to their differences in tumor biology and consecutively better prognosis.

Abstract
INTRODUCTION The optimal overall treatment time (OTT) from radical surgery to the end of adjuvant radiation therapy for some squamous cell carcinomas has been found to impact treatment outcomes. This study aims to identify the impact of OTT on overall survival (OS) for women with completely resected, node-positive squamous cell carcinomas of the vulva. MATERIALS AND METHODS The National Cancer Data Base was queried for women with surgically resected, node-positive vulvar squamous cell carcinomas between 2004 and 2016 who were treated with adjuvant radiation therapy. Kaplan-Meier analysis with log-rank test and Cox proportional hazards tests were utilized for OS calculations. RESULTS A total of 1500 women met inclusion criteria. The median OTT was 104 days. Shorter OTT was associated with age, facility volume, private insurance, and duration of post-operative hospitalization. Median OS with OTT ≤ 104 days was 56.1 months vs 45.4 months if ≥105 days (p = 0.015). On multivariable Cox analysis, OTT was independently associated with an increased risk of death of 0.4% per additional day (95%CI 1.001-1.007, p = 0.003), as were age at diagnosis (HR 1.031 [95%CI 1.024-1.037], p < 0.001), number of nodes positive (HR 1.031 [95%CI 1.024-1.037], p = 0.006), the use of concurrent chemotherapy (HR 0.815 [95%CI 0.693-0.960], p = 0.014) and increasing pT/pN stage. After propensity adjustment for factors predicting a shorter OTT, OTT continued to be associated with an increased risk of death per additional day (HR 1.004 [95%CI 1.001-1.007], p = 0.007). CONCLUSION Overall treatment time is an independent risk factor for death in women being treated with adjuvant radiation therapy following complete resection of node-positive squamous cell carcinoma of the vulva.

Abstract
BACKGROUND Transoral surgery (TOS) has been used to remove pharyngeal and laryngeal cancers with the objective of improving functional without worsening survival. However, there is a risk of postoperative dysphagia, which can severely impair quality of life. The aim of this study was to evaluate the preoperative predictive factors for postoperative dysphagia in patients undergoing TOS. METHODS One hundred and twenty patients who underwent TOS were evaluated in this study. The degree of dysphagia was evaluated using the Functional Outcome Swallowing Scale (FOSS) both preoperatively and 3 months postoperatively. Those whose FOSS stage was maintained postoperatively were classified into the FOSS-M group, while those with increased FOSS stage postopratively were classified into the FOSS-I group. The following parameters were assessed before surgery: age, weight, height, body mass index (BMI), forced expiratory volume in 1 s, and history of head and neck radiotherapy. Videofluoroscopy (VF) was performed preoperatively to evaluate swallowing function using the Penetration-Aspiration Scale (PAS). RESULTS The BMI of the FOSS-M group was significantly higher than that of the FOSS-I group. A history of radiotherapy was significantly more common in the FOSS-I group than in the FOSS-M group. Finally, preoperative PAS in the FOSS-M group was lower than that in the FOSS-I group. CONCLUSION This study suggested that patients with preoperative aspiration detected using VF might develop postoperative dysphagia severely. In addition, preoperative low BMI and a history of previous radiotherapy for head and neck cancer were associated with postoperative dysphagia. Objective examinations such as VF should be performed preoperatively.

Abstract
BACKGROUND/AIM Some patients with unresectable or incompletely resected head-and-neck cancer (SCCHN) cannot tolerate radiochemotherapy. Alternatives are needed that are more effective than conventional radiotherapy alone. PATIENTS AND METHODS This retrospective study investigated patients irradiated for non-metastatic stage IV SCCHN who could not receive concurrent chemotherapy. Eight patients received accelerated radiotherapy with concomitant boost (group A) and 31 patients conventionally fractionated radiotherapy (group B). Groups were matched for tumor site, gender, age, performance score and histologic grade. RESULTS Two-year PFS-rates were 63% in group A vs. 41% in group B, and median PFS-times were 36 vs. 10 months (p=0.48). Two-year OS-rates were 88% vs. 37%, and median OS-times were 44 vs. 14 months (p=0.19). Grade ≥2 radiation dermatitis was significantly (p=0.040) more common in group B; other toxicities were similar. CONCLUSION Accelerated fractionation with concomitant boost appeared superior to conventional fractionation and can be considered for patients with stage IV SCCHN not suitable for radiochemotherapy. Larger studies are needed to confirm these findings.

Abstract
Studying tissue-independent components of cancer and defining pan-cancer subtypes could be addressed using tissue-specific molecular signatures if classification errors are controlled. Since PAM50 is a well-known, United States Food and Drug Administration (FDA)-approved and commercially available breast cancer signature, we applied it with uncertainty assessment to classify tumor samples from over 33 cancer types, discarded unassigned samples, and studied the emerging tumor-agnostic molecular patterns. The percentage of unassigned samples ranged between 55.5% and 86.9% in non-breast tissues, and gene set analysis suggested that the remaining samples could be grouped into two classes (named C1 and C2) regardless of the tissue. The C2 class was more dedifferentiated, more proliferative, with higher centrosome amplification, and potentially more TP53 and RB1 mutations. We identified 28 gene sets and 95 genes mainly associated with cell-cycle progression, cell-cycle checkpoints, and DNA damage that were consistently exacerbated in the C2 class. In some cancer types, the C1/C2 classification was associated with survival and drug sensitivity, and modulated the prognostic meaning of the immune infiltrate. Our results suggest that PAM50 could be repurposed for a pan-cancer context when paired with uncertainty assessment, resulting in two classes with molecular, biological, and clinical implications.

Abstract
Objective This study aims to compare recurrence patterns and outcomes of biologically effective dose (BED10, α/β = 10) of 60-70 Gy with those of a BED10 >70 Gy for locally advanced pancreatic cancer (LAPC). Methods Patients from three centers with a biopsy and a radiographically proven LAPC were retrospectively included and data were prospectively collected from June 2012 to June 2019. Radiotherapy was delivered by stereotactic body radiation therapy. Recurrences were categorized as in-field, marginal, and outside-the-field recurrence. Patients in two groups were required to receive abdominal enhanced contrast CT or MRI every 2-3 months and CA19-9 examinations every month during follow-up. Treatment-related toxicities were evaluated every month. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. Results After propensity score matching, there were 486 patients in each group. The median prescription dose of the two groups was 37 Gy/5-8 f (range: 36-40.8 Gy/5-8 f) and 42 Gy/5-8 f (range: 40-49.6 Gy/5-8 f), respectively. The median OS of patients with a BED10 >70 Gy and a BED10 60-70 Gy was 20.3 months (95% CI: 19.1-21.5 months) and 18.2 months (95% CI: 17.8-18.6 months) respectively (p < 0.001). The median PFS of the two cohorts was 15.4 months (95% CI: 14.2-16.6 months) and 13.3 months (95% CI: 12.9-13.7 months) respectively (p < 0.001). A higher incidence of in-field and marginal recurrence was found in patients with BED10 of 60-70 Gy (in-field: 97/486 versus 72/486, p = 0.034; marginal: 109/486 versus 84/486, p = 0.044). However, more patients with BED10 >70 Gy had grade 2 or 3 acute (87/486 versus 64/486, p = 0.042) and late gastrointestinal toxicities (77/486 versus 55/486, p = 0.039) than those with BED10 of 60-70 Gy. Conclusion BED10 >70 Gy was found to have the best survival benefits along with a higher incidence of acute and late gastrointestinal toxicities. Therefore, a higher dose may be required in the case of patients' good tolerance.

BACKGROUND This study investigated the effects of reconstruction of hypopharyngeal non-circumferential defects with a submental island flap after ablation of hypopharyngeal carcinoma. OBJECTIVES The purpose of our study was to identify advantages and limitations of the submental flap for reconstruction of non-circumferential hypopharyngeal defects. METHODS A total of 27 patients who had stage II-IV hypopharyngeal cancer and underwent pharyngeal reconstruction with a submental flap by the senior author in both Department of Otolaryngology Head Neck Surgery, Chinese PLA General Hospital and Department of Otolaryngology Head Neck Surgery, Beijing Friendship Hospital, Capital Medical University. RESULTS 96.3% (26/27) cases of submental island flap survived. There were two pharyngocutaneous fistulas, one recovered spontaneously, and the other was associated with flap necrosis, underwent neck debridement and flap removal. All except for one patient had decannulation of their nasogastric tube 2 weeks postoperatively. There was no evidence of a stricture or stenosis of the laryngopharynx, nor any sign of aspiration, except for one with esophageal inlet stricture caused by radiotherapy. There were two cases of obvious paraesthesia pharynges due to beard growth at the submental flap after reconstruction. 63.0% (17/27) patients are alive and 37% (10/27) have died of disease. The 3-year survival rate is 56.3% and the 5-year survival rate is 50.0%. CONCLUSION The submental flap reconstruction for moderately sized non-circumferential hypopharyngeal defects is a recommended treatment option.

Abstract
OBJECTIVE Over the years, evidence-based data and technical improvements have consolidated the central role of radiation therapy (RT) in head and neck cancer (HNC) treatment, even in the elderly. This survey aimed to describe the management of the elderly HNC patients among Italian Radiation Oncology Departments (RODs) and provide possible suggestions for improvement. METHODS An online survey based on 43 questions was sent to RODs via email. For each RODs, a radiation oncologist with expertise in HNC was invited to answer questions addressing his/her demographic data, ROD multidisciplinary unit (MU) organisation and ROD management policy in elderly HNC patients. RESULTS In total, 68 RODs answered, representing centres located in 16 Italian regions. MU was considered the core of HNC patient management in almost all the entire country. However, in many RODs, there was minimal access to a routinely comprehensive geriatric assessment at diagnosis. Most treatments were reported by respondents as curative (89% on average) and the preferred treatment technique was intensity modulated radiation therapy (IMRT). A considerable variation between RODs was found for RT target volumes. There was a relation between the specialist's years of experience and type of concomitant systemic therapy prescribed. CONCLUSIONS Substantial differences in elderly HNC management have been found, especially concerning patient clinical evaluation and target volume delineation. This survey shows the necessity to design a prospective national trial to provide a uniform treatment strategy and define an effective patient-centred approach.

Oral Oncol 2020; 111:105045. [PMID: 33091846 PMCID: PMC7572312 DOI: 10.1016/j.oraloncology.2020.105045] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 09/27/2020] [Accepted: 10/08/2020] [Indexed: 12/31/2022]
Abstract
The incidence of head and neck squamous cell carcinoma (HNSCC) is increasing worldwide, with over three quarters of cases now diagnosed in low and middle-income countries (LMICs) with resource-constraints. Loco-regional recurrence remains the predominant pattern of failure mandating adequate local therapy for acceptable loco-regional control and survival. There is high-quality evidence that intensification of treatment by either by adding concurrent chemotherapy or by altering radiotherapy (RT) fractionation improves outcomes in the curative-intent management of loco-regionally advanced HNSCC. Even conservative estimates indicate that >50% of patients in LMIC are unlikely to get access to timely RT, which will only get compounded with the coronavirus disease (COVID)-19 pandemic. The radiation oncology community has been systematically testing altered fractionation schedules in several solid cancers (breast, lung, and head-neck), given the cost-effectiveness, convenience, and compliance to short-course RT regimens. Radiobiological modelling suggests that standard fractionation of 6-7 weeks in HNSCC can be compressed safely into a 4-week schedule to counter accelerated repopulation by increasing the dose per fraction and delivering 5 fractions per week which is currently being tested in the ongoing multicentric trial of hypo- vs normo-fractionated accelerated RT (HYPNO study). Herein, we discuss the radiobiological basis of curative-intent hypofractionated-accelerated RT schedule delivering 55 Gy in 20 fractions over 4 weeks in HNSCC followed by critical appraisal of the published literature on such regimens with concurrent systemic therapy and its inherent resource-sparing potential applicable across large parts of the world particularly in the context of the ongoing COVID-19 pandemic.

Abstract
BACKGROUND AND PURPOSE The FiGaRO trial assessed the feasibility and safety of using an FDG-PET-based dose-painting technique to deliver a radiotherapy (RT) boostto the FDG-avid primary tumour in patients with locally advanced high and intermediate risk oropharyngeal cancer. MATERIALS AND METHOD Patients underwent a planning 18FDG-PET-CT scan, immobilised in the treatment position, after one cycle of induction chemotherapy. The volume of persistent FDG-avidity in the primary tumour was escalated to 71.5 Gy in30 fractions delivered using a simultaneous integrated boost Intensity Modulated RT (SIB-IMRT) technique. RT was delivered with concomitant Cisplatin following 2 cycles of induction chemotherapy. The primary outcome was the incidence of grade ≥ 3 late mucosal toxicity 12 months post-treatment, with an excess rate of >10% regarded as unacceptable. RESULTS Twenty-nine patients were included and twenty-four were treated between 2014 and 2018, in two UK centres. Median follow-up was 36 months (range 4-56 months). Pre-defined planning target volume objectives and organ at risk dose constraints were met in all cases. There were no incidents of acute grade 4 toxicity. There were 4 cases of grade ≥ 3 mucosal toxicity at 12 months post-treatment (19.1%). There were no cases of persistent mucosal ulceration at 12 months. Overall survival at 3-years was 87.5%, 92.9% for intermediate and 70.0% for high risk patients. CONCLUSION Late toxicity rates, although higher than anticipated, are comparable to contemporary published data for standard dose chemo-IMRT. Results suggest improved 3y survival rates for high risk patients. This approach merits further investigation. ClinicalTrials.gov Identifier: NCT02953197.

Abstract
PURPOSE To assess the efficacy and the tolerance of a split course hypofractionated (SCH) radiotherapy (RT) protocol in head and neck cancer (HNC) for eldery and/or unfit patients (pts). PATIENTS AND METHODS Pts with HNC treated by SCH-RT in two institutions were included retrospectively. The main SCH RT regimen was two courses of 30 grays (Gy)/10 fractions separated by 2-4 weeks, without any systemic therapy. RESULTS Between February 2012 and January 2019, 75 consecutive patients were analyzed. The median age was 80 years (range: 45.7-98.2) and 53 (70.7%) were men. Sixty-one (81.3%) pts had stage III/IV disease and 54 (72%) had at least two comorbidities. All of them were treated with intensity-modulated radiotherapy. Median follow-up was 10.6 months (range: 3.1-58.3). Local control at 12 and 24 months was 72.8% IC95%[62-85.5] and 51.7% IC95%[38.1-70.1] respectively. Progression free survival (PFS) at 12 and 24 months were 47.7% IC95%[37.4-60.8] and 41% IC95%[15-36.4] respectively, with a median of 11.5 months IC95%[8.9-17]. OS at 12 and 24 months were 60.4% IC95%[50-73.1] and 41% IC95%[30.6-54.9] respectively, with a median of 19.3 months IC95%[11.9-25.8]. Acute and late grade 3 or higher toxicities occurred for 6 (8%) and 3 (4%) pts. CONCLUSION The present SCH-RT regimen seems effective, well-tolerated and could represent an alternative to palliative strategies for pts deemed unfit for standard exclusive RT.

CDK 4/6 Inhibition Overcomes Acquired and Inherent Resistance to PI3Kα Inhibition in Pre-Clinical Models of Head and Neck Squamous Cell Carcinoma. J Clin Med 2020; 9:jcm9103214. [PMID: 33036331 PMCID: PMC7601167 DOI: 10.3390/jcm9103214] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 09/24/2020] [Accepted: 10/02/2020] [Indexed: 12/28/2022] Open
Abstract
Activating alterations in PIK3CA, the gene coding for the catalytic subunit of phosphoinositide-3-kinase (PI3K), are prevalent in head and neck squamous cell carcinoma (HNSCC) and thought to be one of the main drivers of these tumors. However, early clinical trials on PI3K inhibitors (PI3Ki) have been disappointing due to the limited durability of the activity of these drugs. To investigate the resistance mechanisms to PI3Ki and attempt to overcome them, we conducted a molecular-based study using both HNSCC cell lines and patient-derived xenografts (PDXs). We sought to simulate and dissect the molecular pathways that come into play in PIK3CA-altered HNSCC treated with isoform-specific PI3Ki (BYL719, GDC0032). In vitro assays of cell viability and protein expression indicate that activation of the mTOR and cyclin D1 pathways is associated with resistance to PI3Ki. Specifically, in BYL719-resistant cells, BYL719 treatment did not induce pS6 and pRB inhibition as detected in BYL719-sensitive cells. By combining PI3Ki with either mammalian target of rapamycin complex 1 (mTORC1) or cyclin D1 kinase (CDK) 4/6 specific inhibitors (RAD001 and abemaciclib, respectively), we were able to overcome the acquired resistance. Furthermore, we found that PI3Ki and CDK 4/6 inhibitors have a synergistic anti-tumor effect when combined in human papillomavirus (HPV)-negative/PIK3CA-WT tumors. These findings provide a rationale for combining PI3Ki and CDK 4/6 inhibitors to enhance anti-tumor efficacy in HNSCC patients.

Abstract
BACKGROUND This study was designed to test the hypothesis that the effectiveness of intensive treatment for locoregionally advanced head and neck cancer (LAHNC) depends on the proportion of patients' overall event risk attributable to cancer. METHODS This study analyzed 22,339 patients with LAHNC treated in 81 randomized trials testing altered fractionation (AFX; Meta-Analysis of Radiotherapy in Squamous Cell Carcinomas of Head and Neck [MARCH] data set) or chemotherapy (Meta-Analysis of Chemotherapy in Head and Neck Cancer [MACH-NC] data set). Generalized competing event regression was applied to the control arms in MARCH, and patients were stratified by tertile according to the ω score, which quantified the relative hazard for cancer versus competing events. The classifier was externally validated on the MACH-NC data set. The study tested for interactions between the ω score and treatment effects on overall survival (OS). RESULTS Factors associated with a higher ω score were a younger age, a better performance status, an oral cavity site, higher T and N categories, and a p16-negative/unknown status. The effect of AFX on OS was greater in patients with high ω scores (hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.85-0.99) and medium ω scores (HR, 0.91; 95% CI, 0.84-0.98) versus low ω scores (HR, 0.97; 95% CI, 0.90-1.05; P for interaction = .086). The effect of chemotherapy on OS was significantly greater in patients with high ω scores (HR, 0.81; 95% CI, 0.75-0.88) and medium ω scores (HR, 0.86; 95% CI, 0.78-0.93) versus low ω scores (HR, 0.96; 95% CI, 0.86-1.08; P for interaction = .011). CONCLUSIONS LAHNC patients with a higher risk of cancer progression relative to competing mortality, as reflected by a higher ω score, selectively benefit from more intensive treatment.
