Treatment of elderly patients with head and neck cancer in an aging society: Focus on geriatric assessment and surgical treatment

Previous studies of the treatment of elderly head and neck cancer (HNC) patients were very limited and sometimes controversial. Although conclusions differ across various reports, it is often concluded that advanced chronological age does not directly affect prognosis, but that comorbidities and declines in physical and cognitive functions promote the occurrence of adverse events, especially with surgical treatment. Geriatric assessment (GA) and its screening tools are keys to help us understand overall health status and problems, predict life expectancy and treatment tolerance, and to influence treatment choices and interventions to improve treatment compliance. In addition, personal beliefs and values play a large role in determining policies for HNC treatment for elderly patients, and a multidisciplinary approach is important to support this. In this review, past research on HNC in older adults is presented, and the current evidence is explained, focusing on the management of elderly HNC patients, with an emphasis on the existing reports on each treatment stage and modality, especially the surgical procedures.

Outcome of radiotherapy for the treatment of laryngeal squamous cell carcinoma in the very elderly population

BACKGROUND

Treatment selection for squamous cell carcinoma patients aged over 84 years is controversial. This retrospective chart review examined and compared characteristics of laryngeal squamous cell carcinoma in very elderly (over 84 years) and younger patients (approximately 65 years). The secondary objective was to further evaluate the outcome of radiotherapy as a treatment modality in this patient population.

METHODS

Of all 23 very elderly patients with laryngeal squamous cell carcinoma treated with radiotherapy, with or without surgery, in the Davidoff Cancer Center, from 1992 to 2012, 19 had sufficient data for analysis, and comprised the study group.

RESULTS

Median age at diagnosis was 86 years. Disease stage at diagnosis was I, II, III and IVA in 53 per cent, 21 per cent, 21 per cent and 5 per cent, respectively. Median radiotherapy dose was 60 Gy given in 25 fractions. Three patients had recurrence. No patient discontinued treatment because of toxicity. Median overall survival was 3.6 years (range, 0-10 years).

CONCLUSION

Very elderly laryngeal squamous cell carcinoma patients may derive a similar survival advantage as younger counterparts. Modern radiotherapy is effective and safe for treating laryngeal squamous cell carcinoma in this study population. Further, large-scale studies are needed.

Primary concurrent chemoradiation therapy with triweekly cisplatin as a standard protocol in patients aged ≥65 years with head and neck squamous cell carcinoma

AIM

To evaluate the results of primary concurrent chemoradiation therapy (CCRT) with triweekly cisplatin in patients with head and neck squamous cell carcinoma (HNSCC) aged ≥65 years by comparing these patients to those aged < 65 years.

METHODS

This prospective, single-center study enrolled patients with HNSCC for whom CCRT was indicated as the primary treatment. The major endpoints were progression-free survival (PFS) and overall survival (OS).

RESULTS

A total of 169 patients were enrolled; 75 (44.4%) and 94 (55.6%) patients were aged ≥65 and < 65 years, respectively. The mean cumulative cisplatin doses were 192.8 mg/m2 and 212.3 mg/m2 in patients ≥65 and < 65, respectively (p < .001). The incidence rates of any grade 3-4 toxicities were 37.3% and 51.1% in the age ≥65 and < 65 groups, respectively (p = .085). The 5-year locoregional control, distant control, PFS, ultimate PFS, and disease-specific survival were comparable between both groups. The 5-year OS was significantly lower in the ≥65 group than the < 65 group (65.5% vs. 86.4%, p = .010) due to a lower salvage rate and higher incidence of non-HNSCC-related death. In a Cox regression analysis, age ≥65 years was not associated with increased risk of treatment failure but was associated with higher overall death rate (hazard ratio, 2.590; 95% confidence interval, 1.219-5.502; p = .013).

CONCLUSION

CCRT with a triweekly cisplatin regimen could act as the standard of ca for HNSCC in elderly patients. However, the relatively lower OS compared to younger patients should be acknowledged, despite a favorable disease control rates.

Clinical and Therapeutic Considerations for Older Adults with Head and Neck Cancer

Approximately 30% of patients with head and neck squamous cell carcinoma (HNSCC) are at least 70 years of age, and this percentage is expected to increase as the population increases and lives longer. Elderly patients are underrepresented in head and neck oncology clinical trials, and there is minimal evidence on the management of HNSCC for this population. Subsequently, despite their best intentions, physicians may unknowingly recommend an ill-suited course of therapy, which may result in suboptimal oncological or functional outcomes or adverse events. Surgical approaches have the potential to carry a higher risk of morbidity and mortality in older adults, especially in patients with multiple comorbidities. Definitive radiation therapy treatment in patients with HNSCC frequently involves 7 weeks of daily radiation, sometimes with concurrent chemotherapy, and this demanding treatment can be difficult for older adult patients, which may lead to treatment interruptions, potential removal of concurrent systemic therapy, compromised outcomes, and diminished quality of life. There are clinical trials currently underway investigating altered fractionation regimens and novel, less toxic systemic treatments in this population. This review provides an overview of how best to approach an older adult with HNSCC, from initial work-up to treatment selection.

Nonsurgical Treatment Strategies for Elderly Head and Neck Cancer Patients: An Emerging Subject Worldwide

Consistent with the increasing rate of head and neck cancers among elderly adults, there has been an increase in the rate of those receiving nonsurgical treatments to maintain their function and quality of life. However, various problems, such as poor tolerance to chemoradiotherapy-related toxicity, are of greater concern in elderly adults than in younger individuals. In this review, we describe adverse events that should be particularly noted in elderly patients and provide an overview of countermeasures in nonsurgical treatments. We mainly focus on cisplatin-based chemoradiotherapy-the primary treatment for head and neck squamous cell carcinoma (HNSCC). Furthermore, we review the molecular targeted drugs and immune checkpoint inhibitors for elderly patients with HNSCC. Although the number of older patients is increasing worldwide, clinical trials aimed at determining the standard of care typically enroll younger or well-conditioned elderly patients. There is still very little evidence for treating elderly HNSCC older patients, and the question of optimal treatment needs to be explored.

Management of Older Adults with Locally Advanced Head and Neck Cancer

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.

Intra-arterial chemoradiotherapy for locally advanced buccal mucosal cancer in an elderly patient with multiple comorbidities: A case report

BACKGROUND

The management of locally advanced oral cavity squamous cell carcinoma (LA-OCScc) in elderly patients with multiple comorbidities is difficult.

CASE

We report the case of an elderly patient with buccal mucosal squamous cell carcinoma as well as chronic renal dysfunction, hepatic cirrhosis, rheumatoid arthritis, and metachronous diffuse large B-cell lymphoma. We performed radiation therapy (a total dose of 70 Gy in 35 fractions) and six cycles of intra-arterial chemotherapy with 40 mg/m² cisplatin per week. After treatment, the tumor completely disappeared, and there was no recurrence or deterioration of comorbidities during the 12-month follow-up period.

CONCLUSION

Intra-arterial chemoradiotherapy may be a good treatment option for LA-OCScc in elderly patients with multiple comorbidities.

Patterns-of-Care Analysis for Radiotherapy of Elderly Head-and-Neck Cancer Patients: A Trinational Survey in Germany, Austria and Switzerland

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.

Treatment Outcomes and the Safety of Chemoradiotherapy With High-Dose CDDP for Elderly Patients With Head and Neck Squamous Cell Carcinoma: A Propensity Score Matching Study

Objective: We aimed to compare the outcomes and safety of chemoradiotherapy (CRT) between elderly and non-elderly patients with head and neck squamous cell carcinoma (HNSCC). It is difficult to assess the causal effect of age because of possible differences in general conditions among individuals. Therefore, we adjusted the background factors of elderly and non-elderly patients using propensity score matching (PSM).

Methods: A total of 146 patients with HNSCC who received CRT were divided into an elderly (≥70 years, n = 35) and non-elderly group (<70 years, n = 111). Pre-treatment characteristics, including the performance status, Charlson comorbidity index, body mass index, primary site, and TNM stage were adjusted by PSM. We compared the outcomes and safety of CRT with high-dose single-agent cisplatin (CDDP) as well as outcomes following recurrence between the groups, before and after PSM.

Results: The total dose of CDDP administered during CRT was significantly lower in the elderly group before PSM. However, it became comparable to the non-elderly group and adverse events did not differ between the groups following PSM, resulting in a comparable CRT completion rate. Overall-, disease specific-, and progression-free survivals of elderly patients were comparable to those of non-elderly patients following PSM. In contrast, elderly patients with recurrence could receive fewer salvage treatments than their non-elderly counterparts, resulting in worse survival.

Conclusions: CRT with high-dose CDDP is safe and effective for the treatment of elderly patients with HNSCC. However, salvage treatments can be rarely conducted for elderly patients with a recurrence, considering a deterioration of their general condition.

Treatment Outcomes of Head and Neck Cancer Patients in the Elderly Receiving Different Chemoradiation Combinations: A Single-Center Experience

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.

Use of the Geriatric-8 screening tool to predict prognosis and complications in older adults with head and neck cancer: A prospective, observational study

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.

Clinical characteristics, treatment methods and prognoses of patients with oral squamous cell carcinoma in Japanese population: a single institution retrospective cohort study

BACKGROUND

The status of oral cancer therapy in elderly patients in Japan, where ageing is rapidly progressing, may serve as a model for other countries with similar demographics. There is controversy over what kind of treatment should be applied and how aggressively it should be applied to very elderly patients who have exceeded the average life expectancy. Given that 85 years is approximately the overall Japanese life expectancy at birth, we considered a threshold of 85 years and hypothesized that the prognosis of oral squamous cell carcinoma (SCC) patients aged ≥85 years was not inferior to that of those < 85 years. The aim of the present study was to investigate the clinical characteristics, treatment methods, and prognoses of Japanese oral SCC patients aged ≥85 years.

METHODS

A retrospective cohort study was performed. The data of patients with primary oral SCC (n = 358) from 2005 to 2018 in our institute were extracted from electronic medical records. A total of 358 patients with oral SCC were divided into two groups (≥85 years group [n = 26] and < 85 years group [n = 332]) based on the age threshold of 85 years at the first visit. Kaplan-Meier survival analyses and Cox proportional hazard models were used to analyse overall survival (OS) and hazard ratios (HRs) according to age group, treatment, and TNM classification.

RESULTS

There was no difference in the 5-year OS rate between the ≥85 years and < 85 years groups (80.8% vs. 82.2%, P = 0.359). This finding was the same in the operative (94.7% vs. 85.8%, P = 0.556) and non-operative (42.9% vs. 33.2%, P = 0.762) groups, indicating that age did not affect prognosis. Mortality was lower in the operative group than in the non-operative group (adjusted HR: 0.276, 95% CI: 0.156-0.489, P < 0.001), suggesting that surgery is a superior method. However, non-surgical treatment was selected at a higher rate in the ≥85 years group (26.9% vs. 11.1%, P = 0.028).

CONCLUSIONS

This study suggests the prognosis of ≥85-year-old patients was not inferior to that of < 85-year-old patients. We recommend that surgery as the first choice treatment for ≥85-year-old patients with oral SCC who can tolerate surgery should be performed.

Tolerance of Radical Radiotherapy Among Elderly Head and Neck Cancer Patients

Head and neck cancers usually occur in the elderly age group and about half of the cases occur at the age > 60 years with majority detected in an advanced stage with increased morbidity and decreasing compliance to therapy. Since there are limited data available for the adequate treatment of elderly head and neck cancer patients, we proposed a study to analyze tolerance and response based on age, site, modality of treatment received, and implication of nutrition vs weight loss during treatment. Fifty-five patients were enrolled in this study, which was conducted between November 2015 and April 2017, and those who met the eligibility criteria were evaluated with a detailed history and physical examination, and biochemical, pathological, and radiological investigations. Patients were staged based on TNM staging and treated as per the standard guidelines. Patients were assessed with the weekly routine blood investigation, weight loss, and toxicity. The response was assessed after 6 weeks and documented as per RECIST criteria. 52/55 (94.5%) patients completed the treatment, and 48/55 (92.3%) had a complete response at 6 weeks (p value 0.000) with a mean treatment duration of 46.67 days and mean weight loss of 5.44 kg with 55.4% having GR-II mucositis, 40% having GRIII mucositis at the time of completion of treatment. Sixty-eight percent having GRII and 38.2% having GR I dermatitis and 80% had moderate pain. Subgroup analysis was done based on age, site, and treatment modality. Patients were also assessed for nutrition vs weight loss. We concluded that elderly patients tolerate and respond well to radical treatment with acceptable toxicities; hence, age should not be a barrier to decide treatment.

Long-term quality of life in older patients with HPV-related oropharyngeal cancer

BACKGROUND

We explored if age affects quality of life (QOL) in survivors of locally advanced human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (SCC).

METHODS

In a cross-sectional survey of 185 patients, at least 12 months from radiation, we evaluated generic (EuroQOL-5D questionnaire [EQ-5D]) and head and neck specific (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck 35-questions [EORTC-QLQ-H&N35]) QOL questionnaires and compared differences between younger (<65) and older (≥65) patients.

RESULTS

The median age was 57.0 years (range 25-77 years), and 31 patients (16.8%) were ≥65 years old. There was no significant difference in EQ-5D global QOL scores by age (P = .53). Patients ≥65 years reported more immobility (P < .01), problems with social eating (P < .0001), and coughing (P < .01). Patients ≥65 years were not more likely to ever require a gastrostomy (P = .24) but were more likely to remain gastrostomy-dependent at the time of the survey (P = .02).

CONCLUSION

Despite similar generic QOL, older survivors may have more mobility problems and issues with social eating compared with younger survivors deserving of further evaluation.

Oropharyngeal cancer is no longer a disease of younger patients and the prognostic advantage of Human Papillomavirus is attenuated among older patients: Analysis of the National Cancer Database

OBJECTIVES

HPV-positive oropharyngeal cancer (OPC) patients have been observed to be younger than patients with HPV-negative OPC at diagnosis. We evaluated recent trends in age at OPC diagnosis, and whether older age attenuates the survival benefit of HPV-positive tumor status.

MATERIALS AND METHODS

Patients diagnosed with OPC from 2004 to 2014 represented in the National Cancer Database were included. HPV tumor status was available after 2010. Trends in age by calendar year were compared using linear regression. Overall survival was compared using Cox Proportional Hazards models.

RESULTS

The mean age of OPC patients (N = 119,611) increased significantly from 2004 to 2014 (ß = 0.21 years of age per calendar year, 95% confidence interval [CI] = 0.19-0.23). The increase in age from 2010 to 2014 was similar for HPV-positive (N = 21,880; ß = 0.63, 95%CI = 0.53-0.72) and HPV-negative (N = 11,504; ß = 0.59, 95%CI = 0.45-0.74) patients. Between 2010 and 2014, the proportion of OPCs that were HPV-positive increased significantly for all age groups, including for patients ≥70 years old (from 45% to 60%, p_trend < 0.001). Although patients ≥70 years with HPV-OPC had improved survival compared to those with HPV-negative OPC (adjusted hazard ratio [aHR] = 0.65, 95%CI = 0.55-0.76), the survival benefit of HPV-positive tumor status was significantly attenuated compared to younger HPV-OPC patients (50-59 years: aHR = 0.45, 95%CI = 0.39-0.51; p_interaction < 0.001).

CONCLUSION

The age at OPC diagnosis is increasing for both HPV-positive and HPV-negative patients, and a rising proportion of older patients have HPV-positive tumors. These findings dispel the notion that HPV-positive OPC is a disease of younger patients, identify a growing elderly population of HPV-positive OPC patients with reduced survival, and have implications for evolving treatment paradigms.

Managing older patients with head and neck cancer: The non-surgical curative approach

Managing older patients with head and neck cancers poses a challenge due to the often reduced levels of physiological reserve, the frequent comorbidities and treatment related toxicity. These factors have implications on speech, breathing and swallowing functions. Treatment management plans in these patients may result in de-intensification strategies and as a result of this, use of non-standard treatments is increasing. There have been published reports that indicate the addition of concurrent systemic therapy to radiation in selected older patients is feasible, and produces outcomes comparable with younger patients. However, some other studies including meta-analyses suggest a lack of real survival benefit with the addition of chemotherapy. So, the key point appears to be the optimal patient selection. Appropriate geriatric and frailty assessments are required to help determine the optimal treatment for older patients with head and neck cancer. Treatment for this population still needs to be well defined and optimized in both modality and intensity. Qualitative studies are also required to address short and long-term post-treatment quality-of-life and survivorship issues in this specific patient population. This review summarizes the evidence available regarding the non-surgical management of older patients with head and neck cancers.

Increasing prevalence of human papillomavirus-positive oropharyngeal cancers among older adults

BACKGROUND

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing among older adults. It is unknown whether these trends can be explained by human papillomavirus (HPV) and whether HPV-related tumors remain associated with an improved prognosis among older patients.

METHODS

In a retrospective study of OPSCCs diagnosed from 1995 to 2013 at 2 National Comprehensive Cancer Network-designated cancer centers, p16 immunohistochemistry and in situ hybridization (ISH) for HPV-16, high-risk DNA, and/or E6/E7 RNA were performed. The median age at diagnosis was compared by p16 and ISH tumor status. Trends in age were analyzed with nonparametric trends. Survival was analyzed with the Kaplan-Meier method and Cox proportional hazards models.

RESULTS

Among 239 patients, 144 (60%) were p16-positive. During 1998-2013, the median age increased among p16-positive patients (P_trend = .01) but not among p16-negative patients (P_trend = .71). The median age of p16-positive patients increased from 53 years (interquartile range [IQR] in 1995-2000, 45-65 years) to 58 years (IQR for 2001-2013, 53-64 years). Among patients ≥ 65 years old, the proportion of OPSCCs that were p16-positive increased from 41% during 1995-2000 to 75% during 2007-2013 (P_trend = .04). Among all age groups, including older patients, a p16-positive tumor status conferred improved overall survival in comparison with a p16-negative status.

CONCLUSIONS

The median age at diagnosis for HPV-related OPSCC is increasing as the proportion of OPSCCs caused by HPV rises among older adults. The favorable survival conferred by an HPV-positive tumor status persists in older adults. Cancer 2018;124:2993-9. © 2018 American Cancer Society.

US oncology-wide incidence, duration, costs and deaths from chemoradiation mucositis and antimucositis therapy benefits

Approximate oncology-wide incidence, duration, costs and deaths associated with mucositis and identify health economic benefits of antimucositis therapies. Review the literature relevant to the clinical experience of mucositis by pathophysiology, incidence, duration, costs and deaths. Use US insurance actuarial and epidemiology on cancer to generalize an oncology-wide impact of toxic mucositis. Toxic mucositis causes oropharyngoesophageal ulcerations, chemo-induced nausea, vomiting and diarrhea. Acutely, it lasts 102 days/six cycles of chemotherapy, 60 days in human stem-cell transplantation patients and 70-84 days in head and neck cancer patients at annual costs of US$13.23 billion/522,166 treated patients (US$20,892/erosive-type mucositis patient, US$25,337/physiologic mucositis patient) and 46,699 deaths. Using antimucositis therapies prior to 2013 provided fractional benefits at high costs. By completely preventing and rapidly reversing mucositis, high-potency polymerized cross-linked sucralfate promises superior health economic benefits.

Common oral complications of head and neck cancer radiation therapy: mucositis, infections, saliva change, fibrosis, sensory dysfunctions, dental caries, periodontal disease, and osteoradionecrosis

Patients undergoing radiation therapy for the head and neck are susceptible to a significant and often abrupt deterioration in their oral health. The oral morbidities of radiation therapy include but are not limited to an increased susceptibility to dental caries and periodontal disease. They also include profound and often permanent functional and sensory changes involving the oral soft tissue. These changes range from oral mucositis experienced during and soon after treatment, mucosal opportunistic infections, neurosensory disorders, and tissue fibrosis. Many of the oral soft tissue changes following radiation therapy are difficult challenges to the patients and their caregivers and require life-long strategies to alleviate their deleterious effect on basic life functions and on the quality of life. We discuss the presentation, prognosis, and management strategies of the dental structure and oral soft tissue morbidities resulting from the administration of therapeutic radiation in head and neck patient. A case for a collaborative and integrated multidisciplinary approach to the management of these patients is made, with specific recommendation to include knowledgeable and experienced oral health care professionals in the treatment team.

Adjuvant chemoradiation does not improve survival in elderly patients with high-risk resected head and neck cancer

OBJECTIVES/HYPOTHESIS

Randomized trials have demonstrated that adjuvant chemoradiotherapy (CRT) confers an overall survival (OS) benefit over adjuvant radiation therapy (RT) alone in patients with resected head and neck squamous cell carcinoma (HNSCC) with adverse pathologic features (positive surgical margins [SM+] and/or extracapsular extension [ECE]). Whether this OS benefit exists in an elderly population remains unknown.

STUDY DESIGN

Retrospective database study.

METHODS

Using the National Cancer Database, we identified 1,686 elderly patients (age ≥70 years) with resected HNSCC with SM+ and/or ECE, who received adjuvant CRT (491 patients, 29%) or adjuvant RT alone (1,195 patients, 71%) between 1998 and 2011. Three-year survival rates were estimated using the Kaplan-Meier method both before and after propensity score matching (PSM). Crude and adjusted hazard ratios (HR) with 95% confidence intervals (CI) were computed using Cox regression modeling.

RESULTS

Median follow-up was 23.5 and 42.8 months for all and surviving patients, respectively. Three-year OS was 50.7% and 44.4% among patients receiving adjuvant CRT and RT alone, respectively (P = .002). On multivariate analysis, there was no significant improvement in OS with adjuvant CRT relative to adjuvant RT alone (HR: 0.88, 95% CI: 0.73-1.06). Similarly, a PSM cohort showed no significant difference in the 3-year OS for patients receiving adjuvant CRT versus adjuvant RT alone (48.8% and 50.9%, respectively; P = .839).

CONCLUSIONS

Although the addition of chemotherapy to adjuvant RT has been proven effective in randomized trials of patients with resected HNSCC with SM+ or ECE, it may be less efficacious in an elderly patient population treated outside of a controlled trial setting.

The Older Adult With Locoregionally Advanced Head and Neck Squamous Cell Carcinoma: Knowledge Gaps and Future Direction in Assessment and Treatment

Older adults with head and neck squamous cell carcinoma (HNSCC) pose unique treatment and supportive care challenges to oncologists and other cancer care providers. The majority of patients with HNSCC present with locoregionally advanced disease, for which combined-modality treatment integrating chemotherapy and radiation therapy is often necessary to maximize tumor control. However, applying these approaches to an older population with concomitant comorbidities and a higher risk of functional impairments remains challenging and is exacerbated by the paucity of studies involving older adults. The purpose of this article is to identify knowledge gaps in the evaluation and management of older adults with HNSCC-particularly those undergoing concurrent chemoradiation therapy-and their caregivers through a review of the literature conducted by clinicians, researchers, and patient advocates. The findings highlight the importance of a geriatric assessment and the therapeutic paradigms and challenges relevant to this population. Furthermore, we identify the need for additional research and interventions related to key supportive care issues that arise during and after treatment in older adults with locoregionally advanced HNSCC. On the basis of our findings, we prioritize these issues to guide future patient-oriented research endeavors to address these knowledge gaps and thus better serve this growing patient population.

Tumor necrosis and complete resection has significant impacts on survival in patients with limited-stage upper aerodigestive tract NK/T cell lymphoma

Tumor necrosis (TN) is associated with worse prognosis in several solid cancers. Whether TN predicts poor outcome in natural killer cell / T cell lymphoma (NKTCL) is unclear. We investigated the clinical impact of TN on survival and other novel prognostic parameters in upper aero-digestive tract (UAT) NKTCL of 100 patients with limited stage. TN was significantly associated with poor performance status (p = 0.049), high Korean Prognostic Index score (p = 0.024), high C-reactive protein/albumin ratio (p = 0.003), higher maximum standard uptake value on positron emission tomography/computed tomography (PET/CT) (p = 0.008) and higher metabolic tumor volume (MTV) on PET/CT (p < 0.001). In univariate and multivariate analyses, progression-free survival and overall survival were independently associated with High MTV status (p = 0.001, p = 0.032), TN (p = 0.018, p = 0.009), local tumor invasiveness (p = 0.007, p = 0.035), complete resection (p = 0.020, p = 0.028) and regional lymph node involvement (p < 0.001, p < 0.001). TN and complete resection are concluded to be novel independent prognostic factors in patients with UAT NKTCL.

The toxicity and efficacy of concomitant chemoradiotherapy in patients aged 70 years and older with oropharyngeal carcinoma in the intensity-modulated radiotherapy era

BACKGROUND

Despite controversy surrounding its benefit, the use of concomitant chemoradiotherapy (CCRT) in patients with oropharyngeal squamous cell carcinoma (OPSCC) who are aged > 70 years is increasing. However, to the authors' knowledge, few studies to date have compared the outcomes of different systemic treatments in this population.

METHODS

Records from 74 patients aged ≥ 70 years with stage III to stage IVB OPSCC who were undergoing CCRT from 2002 to 2013 at a single institution were reviewed. Patients were stratified according to the systemic therapy received, including cisplatin, carboplatin with either 5-fluorouracil or paclitaxel (CARB), or cetuximab to compare oncologic outcome and toxicity.

RESULTS

The median follow-up was 36 months. The median age of the patients was 75.3 years (range, 70-91 years), with significantly older patients receiving cetuximab (P = .03). A total of 28, 20, and 26 patients, respectively, received CCRT with cisplatin, CARB, and cetuximab. RT interruptions of > 1 day were needed in 4% of patients receiving cisplatin, 20% of patients receiving CARB, and 15% of patients receiving cetuximab (P = .19). Unplanned hospitalizations during CCRT occurred in 25%, 55%, and 58%, respectively, of patients receiving cisplatin, CARB, and cetuximab (P = .03). There were 2 treatment-related deaths, both of which occurred among the patients who were treated with cetuximab. At 5 years, locoregional control was achieved in 100%, 88%, and 60% (P<.001), respectively, and the overall survival rate was 87%, 61%, and 47% (P = .03), respectively, among patients treated with cisplatin, CARB, and cetuximab.

CONCLUSIONS

Toxicity from CCRT remains a challenge for older adults with OPSCC. Herein, the authors found no evidence that this toxicity was mitigated by treatment with cetuximab. Nevertheless, a subset of patients aged ≥70 years appear to tolerate cisplatin-based treatment with acceptable toxicity and excellent outcomes. Further identification of this patient subgroup is crucial to optimize therapy for older patients with OPSCC. Cancer 2017;123:1345-1353. © 2016 American Cancer Society.

Induction Chemotherapy Followed by Radiotherapy versus Concurrent Chemoradiotherapy in elderly patients with nasopharyngeal carcinoma: finding from a propensity-matched analysis

Background

To date, no guideline is proposed for elderly nasopharyngeal carcinoma (NPC) due to lack of prospective clinical trials. The present study comparing the survivals and toxicities in elderly NPC patients received either induction chemotherapy followed by radiotherapy(IC + RT) or concurrent chemoradiotherapy (CCRT) was therefore undertaken to provide a more accurate basis for future clinical practice.

Methods

The eligible elderly NPC patients were retrospectively enrolled. Propensity score matching generated a matched cohort (1:2) composed from CCRT and IC + RT groups. The survivals and treatment-induced toxicities were compared between two groups. Multivariable analysis was carried to identify significant prognostic factors.

Results

The 5-year overall survival, cancer-specific survival, locoregional failure-free survival, distant failure-free survival for all patients were 58.3 %, 62.7 %, 88.7 %, 83.0 %, respectively. No significant survival differences were found between CCRT and IC + RT groups in the propensity-matched cohort. In comparison with the patients who received IC + RT, patients who underwent CCRT were associated with more severe acute toxicities including leucopenia (30 % vs. 6.8 %, P = 0.005), anemia (20 % vs. 4.1 %, P = 0.027), mucositis (63.3 % vs. 34.2 %, P = 0.007), weight loss (23.4 % vs. 4.1 %, P = 0.009). Basicranial bone involvement was an independent prognostic factor that predicted all-cause death (HR = 0.553, 95 % CI 0.329–0.929; P = 0.025) and cancer specific death (HR = 0.558, 95 % CI 0.321–0.969; P = 0.038) in elderly patients.

Conclusions

In the context of no guideline for elderly NPC, the present study suggested IC + RT should be a preferable modality compared with CCRT, with similar treatment outcomes but less acute toxicities.

Locally advanced head and neck cancer in either the older or the vulnerable adult: Making the case for a team-based, "gero-centric" approach

Multidisciplinary, team-based care goes hand in hand with geriatric oncology paradigms for caring for older adults with cancer. Team-based care was the central theme for the 2015 SIOG Annual Meeting. Team-based approaches to the evaluation and management of older adults with different cancer types, including head and neck cancer, were presented. This review aims to summarize the salient points of that presentation, including a synthesis of recent multidisciplinary, "gero-centric" research efforts to improve the care for older adults with more advanced stages of head and neck cancer.

IMRT/VMAT for malignancies in the head-and-neck region : Outcome in patients aged 80

Objective

Elderly patients with malignant head-and-neck tumors (HNT) often pose a therapeutic challenge. They frequently have significant comorbidities which may influence their ability to tolerate tumor-specific therapies. Our aim was to investigate the outcome of patients aged 80+ years undergoing curative intent intensity- or volume-modulated radiation therapy (IMRT/VMAT).

Methods

We retrospectively reviewed our HNT patients aged 80+ treated with curative IMRT/VMAT from December 2003 to November 2015. Overall survival (OS), disease-free survival (DFS), local control (LC), and treatment tolerance were assessed. Outcome results were compared with that of a younger HNT patient cohort from our hospital.

Results

A total of 140 consecutive patients were included (65 postoperative, 75 definitive). Mean/median age at treatment start was 84.8/84.1 years (range 80–96 years). Mean/median follow-up time was 25/16 months (range 2–92 months). Of the 140 patients, 80 were alive with no evidence of disease when last seen, 28 had died due to the cancer, 12 remained alive with disease, the remaining 20 died intercurrently. Systemic concomitant therapy was administered in 7 %. Late grade 3–4 toxicity was observed in 2 %. All patients completed treatment. Hospitalization and feeding tube rates were 26 % and 11 %, respectively. The 2‑/3-year LC, DFS, and OS rates for the entire cohort were 81/80 %, 69/63 %, and 68/66 %, respectively. Squamous cell carcinoma (SCC) patients showed an inferior 3-year OS rate as compared to non-SCC patients (62 % vs 77 %, p = 0.0002), while LC and DFS did not differ. Patients undergoing postoperative radiation attained a higher OS compared to the definitively irradiated subgroup with 74 vs. 60 % at 3 years (p = 0.01); however, DFS rates were similar for both groups (68 vs. 61 %, p = 0.15). Corresponding rates for >1400 HNT patients <80 years treated during the same time interval were 81/80 %, 69/67 %, and 77/72 %, respectively.

Conclusions

Treatment tolerance in our patients aged 80+ was high. These results suggest that elderly HNT patients should not be denied potentially curative treatment strategies.

Survival outcomes with concurrent chemoradiation for elderly patients with locally advanced head and neck cancer according to the National Cancer Data Base

BACKGROUND

The overall survival (OS) benefit of concurrent chemoradiotherapy (CRT) for head and neck squamous cell carcinoma patients older than 70 years is debated. This study examines the outcomes of elderly patients receiving CRT versus radiotherapy (RT) alone.

METHODS

The National Cancer Data Base was queried for patients older than 70 years with nonmetastatic oropharyngeal, laryngeal, or hypopharyngeal cancer (T3-4 or N(+)). CRT was defined as chemotherapy started within 14 days of the initiation of RT. Univariate analysis, multivariate analysis (MVA), propensity score matching (PSM), and recursive partitioning analysis (RPA) were performed.

RESULTS

The study included 4042 patients: 2538 (63%) received CRT. The median follow-up was 19 months. The unadjusted median OS was longer with the addition of CRT (P < .001). OS was superior with CRT in the MVA (hazard ratio [HR], 0.63; 95% confidence interval [CI], 0.58-0.68; P < .001) and PSM analyses (HR, 0.73; 95% CI, 0.66-0.80; P < .001) in comparison with RT alone. According to RPA, CRT was associated with longer OS for patients 81 years or younger with low comorbidity scores and either T1-2/N2-3 disease or T3-4/N0-3 disease. The survival benefit with CRT disappeared for 2 subgroups in the 71- to 81-year age range: those with T1-2, N1, and Charlson-Deyo 0-1 (CD0-1) disease and those with T3-4, N1+, and CD1+ disease. Patients who were older than 81 years did not have increased survival with CRT. The receipt of CRT was associated with a longer duration of RT (odds ratio, 1.74; 95% CI, 1.50-2.01; P < .001).

CONCLUSIONS

Patients older than 70 years should not be denied concurrent chemotherapy solely on the basis of age; additional factors, including the performance status and the tumor stage, should be taken into account. Cancer 2016;122:1533-43. © 2016 American Cancer Society.

Concurrent chemoradiotherapy in older adults with squamous cell head & neck cancer: Evidence and management

OBJECTIVE

Treatment for head and neck cancers incurs substantial associated morbidities, which can be of potentially greater significance in older patients. Though the geriatric population forms a substantial portion of patients with head and neck cancers, this group remains underrepresented in large clinical trials. Hence, management for this unique subpopulation remains empiric and mostly based on data from younger patients.

MATERIALS AND METHODS

Review of key publications on geriatric patients treated for head and neck cancers.

CONCLUSIONS

We discuss data regarding chemoradiation for head and neck cancers, as well as management of associated side effects in this population. We encourage oncologists to treat older patients not as a homogeneous subpopulation, but rather assess several factors associated with potential tolerance to chemoradiotherapy. Aggressive supportive treatments for chemoradiotherapy toxicities are highly encouraged in this population, and with new technical/technological developments, there is potential to continually reduce toxicity in this cohort in the future.

Concurrent chemo-radiotherapy in elderly patients: tolerance and compliance in a series of 137 patients

INTRODUCTION

Aggressive cancer treatment is a challenge in elderly patients. The present study aims to assess tolerance in terms of acute toxicity and compliance of concurrent chemo-radiotherapy (cCRT) in a series of patients aged ≥70 years.

MATERIALS AND METHODS

Clinical records of patients aged ≥70 years who underwent cCRT between January 2005 and December 2013 were reviewed. Concurrent CRT had curative intent in 134 patients (97.8 %) and palliative intent in 3 patients (2.2 %). Chemotherapy (CT) drugs and schedule were selected according to tumor histology. Radiotherapy median dose was 45.0 Gy (range 11-70 Gy) for curative purposes and 54 Gy (range 40-56 Gy) for palliative purposes. Incidence of acute toxicity and compliance to cCRT were analyzed and correlated with age, Karnofsky Performance Status (KPS), and Charlson Comorbidity Index (CCI).

RESULTS

Overall, 137 patients, 82 males (60 %) and 55 females (40 %), median age 74 years (range 70-90 years) were analyzed. Concurrent CRT schedule was completed by 132 patients (96.4 %). Thirty-one of these patients (23.5 %) temporarily interrupted treatment. Hematological toxicity with grade ≥1 was observed in 25 patients (18.2 %), gastrointestinal toxicity in 55 (40.1 %), and genitourinary in 13 (9.5 %). Mucositis with grade ≥1 was recorded in 19 patients (13.9 %). No statistical significant correlation between KPS, CCI, and toxicity was found. A correlation trend between mucositis and patient age (p = 0.05) was observed.

CONCLUSION

Concurrent CRT for elderly was feasible and quite well tolerated. Great attention in prescribing CT dose should be paid to limit acute toxicity.

Clinical outcomes in elderly patients with human papillomavirus-positive squamous cell carcinoma of the oropharynx treated with definitive chemoradiation therapy

BACKGROUND

The benefit of combined chemoradiation in elderly patients with human papillomavirus (HPV)-positive locally advanced oropharyngeal squamous cell carcinoma (SCC) must be balanced with the potential for higher toxicity rates. We performed a retrospective review of our institutional experience.

METHODS

Patients 70 years or older with p16-positive oropharyngeal SCC treated with definitive chemoradiation from 2005 to 2013 were evaluated. Overall survival (OS), disease-free survival (DFS), and locoregional failure-free survival were calculated.

RESULTS

Twenty-one eligible patients had a follow-up of 22.4 months. Estimated 5-year OS, DFS, and locoregional failure-free survival were 76.0%, 40%, and 95%, respectively. There was 1 death from acute toxicity, and 50% had unplanned hospitalizations. Sixty percent had late toxicity, and 6-month feeding tube dependence was 25%.

CONCLUSION

Elderly patients with HPV-positive locally advanced SCC of the oropharynx treated with definitive chemoradiation had good OS but high rates of acute and long-term toxicity. © 2015 Wiley Periodicals, Inc. Head Neck 38: 846-851, 2015.

Trends in chemoradiation use in elderly patients with head and neck cancer: Changing treatment patterns with cetuximab

BACKGROUND

Cetuximab was approved for use in chemoradiation therapy (CRT) for locally advanced head and neck squamous cell carcinoma (HNSCC) in 2006.

METHODS

Among 3705 patients with locally advanced HNSCC identified in the linked Surveillance Epidemiology and End Results (SEER) Medicare database, we assessed treatment trends, including surgery, radiation therapy (RT), CRT, and specific agents used in CRT. We examined the influence of demographic and clinical characteristics on the likelihood of receiving CRT before and after 2006.

RESULTS

Chemoradiation use increased from 29% of patients diagnosed in 2001 to 61% in 2009 (p < .0001). Compared to before 2006, neither age nor comorbidity score was associated with receipt of CRT after 2006. Platinum combinations were the most commonly used concurrent chemotherapies before 2006, but, since then, cetuximab has become the most commonly used agent.

CONCLUSION

The use of CRT has increased substantially and cetuximab may have increased CRT use, especially in older and sicker patients. © 2015 Wiley Periodicals, Inc. Head Neck 38: E165-E171, 2016.

Treatment-related toxicities in older adults with head and neck cancer: A population-based analysis

BACKGROUND

Despite advantages in terms of cancer control and organ preservation, the benefits of chemotherapy and radiation therapy (CTRT) may be offset by potentially severe treatment-related toxicities, particularly in older patients. The objectives of this study were to assess the types and frequencies of toxicities in older adults with locally or regionally advanced head and neck squamous cell carcinoma (HNSCC) who were receiving either primary CTRT or radiation therapy (RT) alone.

METHODS

With Surveillance, Epidemiology, and End Results cancer registry data linked with Medicare claims, patients who were 66 years old or older with locally advanced HNSCC, were diagnosed from 2001 to 2009, and received CTRT or RT alone were identified. Differences in the frequency of toxicity-related hospital admissions and emergency room visits as well as feeding tube use were examined, and controlling for demographic and disease characteristics, this study estimated the impact of chemotherapy on the likelihood of toxicity.

RESULTS

Among patients who received CTRT (n = 1502), 62% had a treatment-related toxicity, whereas 46% of patients who received RT alone (n = 775) did. When the study controlled for demographic and disease characteristics, CTRT patients were twice as likely to experience an acute toxicity in comparison with their RT-only peers. Fifty-five percent of CTRT patients had a feeding tube placed during or after treatment, whereas 28% of the RT-only group did.

CONCLUSIONS

In this population-based cohort of older adults with HNSCC, the rates of acute toxicities and feeding tube use in patients receiving CTRT were considerable. It is possible that for certain older patients, the potential benefit of adding chemotherapy to RT does not outweigh the harms of this combined-modality therapy.

Chemoradiotherapy in elderly patients with advanced head and neck cancer under intensive nutritional support

AIM

To evaluate treatment tolerance, toxicities and survival in elderly patients with advanced head and neck cancer who received inpatient-based intensive nutritional support with concurrent chemoradiotherapy in comparison with younger patients undergoing the same treatment.

METHODS

We retrospectively analyzed the records of 126 stage III, IVA and IVB head and neck cancer patients who were treated with concurrent chemoradiotherapy between 2007 and 2009 under an inpatient-based nutritional support program. The clinical characteristics, treatment tolerance, toxicities and survival of patients older than 65 years were compared with those of identically treated patients younger than 65 years.

RESULTS

There were 21 patients older than 65 years and 105 patients younger than 65 years. Clinical characteristics and treatment toxicities were similar between the groups, except that the elderly were less likely to tolerate cisplatin, experienced more weight loss, required more feeding tube support and tended to have >grade 3 hematological toxicities and to develop sepsis during the period of chemoradiotherapy. The 1- and 2-year disease-free survival and disease-specific survival rates were nearly identical.

CONCLUSION

Age alone should not be considered a contraindication to aggressive chemoradiotherapy for advanced head and neck cancer. Older patients require more careful multidisciplinary assessment of their supportive care needs to ensure successful completion of treatment and avoid further treatment-related toxicity.

Treatment complications and survival in advanced laryngeal cancer: a population-based analysis

OBJECTIVES/HYPOTHESIS

Primary curative treatment of advanced laryngeal cancer may include surgery or chemoradiation, although recommendations vary and both are associated with complications. We evaluated predictors and trends in the use of these modalities and compared rates of complications and overall survival in a population-based cohort of older adults.

STUDY DESIGN

Retrospective population-based cohort study.

METHODS

Using Surveillance Epidemiology and End Results (SEER) cancer registry data linked with Medicare claims, we identified patients over 65 with advanced laryngeal cancer diagnosed 1999 to 2007 who had total laryngectomy (TL) or chemoradiation (CTRT) within 6 months following diagnosis. We identified complications and estimated the impact of treatment on overall survival, using propensity score methods.

RESULTS

The proportion of patients receiving TL declined from 74% in 1999 to 26% in 2007 (P < 0.0001). Almost 20% of the CTRT patients had a tracheostomy following treatment, and 57% had a feeding tube. TL was associated with an 18% lower risk of death, adjusting for patient and disease characteristics. The benefit of TL was greatest in patients with the highest propensity to receive surgery.

CONCLUSION

TL remains an important treatment option in well selected older patients. However, treatment selection is complex; and factors such as functional status, patient preference, surgeon expertise, and post-treatment support services should play a role in treatment decisions.

Feasibility and toxicity of concurrent chemoradiation for elderly patients with head and neck cancer

OBJECTIVES

Although concurrent chemoradiation is increasingly used for patients with locally advanced head and neck cancer, many elderly patients receive radiation alone due to toxicity concerns. We evaluate acute and late toxicity among patients age ≥ 65 who received concurrent chemoradiation for head and neck cancer.

DESIGN

Retrospective review.

SETTING

Tertiary care center.

PARTICIPANTS

Between 6/2003 and 8/2011, 40 consecutive patients age ≥ 65 underwent combined chemoradiation for head and neck cancer. Ten patients were treated in the postoperative setting and 30 underwent definitive chemoradiation. Twenty-eight patients received concurrent platinum-based chemotherapy and 12 received concurrent weekly paclitaxel. Treatment plans were designed to provide a dose of 66-72 Gy at 2-2.12 Gy/fraction to >95% of the gross tumor volume in the definitive setting or for positive margins and 60-66 Gy at 2 Gy/fraction post-operatively. Median follow-up was 23.2 months (range: 0-94.4 months).

MAIN OUTCOMES MEASURES

Acute skin and mucosal toxicity, unplanned treatment interruptions, and chronic treatment related toxicity including gastrostomy tube dependence as graded by the CTCAE v3.0.

RESULTS

Eight patients (20%) required a radiation treatment break of ≥ 3 days. Thirteen (33%) required unplanned hospitalization during or immediately following treatment. No grade 4+ skin or mucosal toxicity was noted. Five patients remained PEG tube dependent at >1 year. One patient developed non-healing mandibular osteoradionecrosis >3 years following chemoradiation. The 2-year Kaplan-Meier estimate of overall survival was 55%.

CONCLUSION

Higher-than-expected rates of in-patient hospitalization with significant acute toxicity were noted in this cohort with a correspondingly high rate of radiation treatment breaks. Late toxicity rates were similar to those observed in historical controls with younger patients. Careful patient selection criteria should be employed for elderly patients considering concurrent chemoradiation for head and neck cancer.

Optimizing perioperative management of geriatric patients with head and neck cancer

Given emerging demographic trends, many more elderly patients are being diagnosed with head and neck cancers. The surgical care paradigm for this cohort of patients must take into account specific challenges inherent to geriatric perioperative management. This article attempts to summarize the existing body of literature relevant to the geriatric head and neck cancer population, and to extrapolate relevant data from geriatric perioperative medicine in order to better understand and guide management decisions. The involvement of geriatricians and of patients' primary care providers may be invaluable in assisting in complex perioperative decision-making and in participating in longitudinal management. Preoperative risk stratification and assessment of medical, social, and functional variables are critical for appropriate decision-making in this challenging patient population.

Patterns of care in older patients with squamous cell carcinoma of the head and neck: a surveillance, epidemiology, and end results-medicare analysis

BACKGROUND

There is growing evidence in the literature that older patients may not benefit from more intensive therapy for head and neck squamous cell carcinoma (HNSCC). A growing number of patients with HNSCC are age 65 years or older; however, much of the evidence base informing treatment decisions is based on substantially younger and healthier clinical trial populations. The purpose of this study was to assess the patterns of care of older HNSCC patients to better understand how age is associated with treatment decisions.

METHODS

Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (1992–2007), we identified patients with non-metastatic HNSCC (n = 10,867) and categorized them by treatment: surgery vs. non-surgery and chemoradiotherapy (CRT) vs. radiotherapy (RT). Multivariate logistic regression models were used to identify variables associated with the receipt of surgery and CRT.

RESULTS

Increasing age was associated with decreased odds of receiving CRT (OR = 0.94; 95% CI 0.93–0.94) but not surgery (OR 1.00; 95% CI 0.99–1.00). Co-morbidity and race were not associated with receipt of either surgery or CRT. Utilization of CRT increased while surgery decreased between 1992 and 2007.

CONCLUSION

Age may influence the receipt of CRT for older HNSCC patients. There has been an increasing trend in the receipt of CRT and a decrease in primary surgery.

Survival and selected outcomes of older adults with locally advanced head/neck cancer treated with chemoradiation therapy

OBJECTIVES

Chemoradiation therapy (CRT) remains a potentially curative treatment in patients with locally advanced head/neck cancer (LA-HNC). However, survival and other outcomes in older patients with head/neck cancer receiving chemoradiotherapy are not well established. This study was performed to elucidate selected outcomes in this patient population.

MATERIALS AND METHODS

Retrospective study of LA-HNC patients ≥ 70 years of age who had received 5-fluorouracil-hydoxyurea-based CRT with a minimum of 3 years of follow up after therapy initiation was performed. Pre-treatment patient- and cancer-related characteristics were recorded. Survival data in addition to gastrostomy tube utilization, swallowing function, and hematologic toxicity were captured.

RESULTS

Eighty-nine patients treated between 1997 and 2009 were eligible for analysis (median age, 76 years; range, 70-94; male, 61%; ECOG PS, 0-1 43%; stage IVA/B, 71%). 86 were evaluable for survival analysis. 5-year overall and event-free survival were both at 32% with a median follow-up time of 39.2 months. The majority (86.5%) were able to complete all planned treatment cycles. A significant proportion of patients, however, required gastrostomy tube during CRT (62%) and developed aspiration during swallowing evaluation post-treatment (44%). Several patients required hospice (9%) or skilled nursing facility (13%) referrals during treatment.

CONCLUSION

Select older adults with LA-HNC can still experience long-term benefits despite 5-year survival rates lower than those historically reported in younger patients undergoing identical CRT regimens although potentially at higher risk for acute toxicities. Assessment and selection of those who can tolerate more intense combined-modality strategies and their long-term outcomes merit further larger, prospective studies.

Treatment of older patients with head and neck cancer: a review

The incidence of head and neck cancer (HNC) in the elderly is increasing. The treatment of HNC often includes multimodality therapy that can be quite morbid. Older patients (herein, defined as ≥65 years) with HNC often have significant comorbidity and impaired functional status that may hinder their ability to receive and tolerate combined modality therapy. They have often been excluded from clinical trials that have defined standards of care. Therefore, tailoring cancer therapy for older patients with HNC can be quite challenging. In this paper, we performed a comprehensive literature review to better understand and discuss issues related to therapeutic recommendations that are particular to patients 65 years and older. Evidence suggests that older patients have similar survival outcomes compared with their younger peers; however, they may experience worse toxicity, especially with treatment intensification. Similarly, older patients may require more supportive care throughout the treatment process. Future studies incorporating geriatric tools for predictive and interventional purposes will potentially allow for improved patient selection and tolerance to intensive treatment.

Feasibility and efficacy of chemoradiotherapy for elderly patients with locoregionally advanced nasopharyngeal carcinoma: results from a matched cohort analysis

BACKGROUND

To clarify the feasibility and efficacy of chemoradiotherapy (CRT) in elderly (age≥65 years) patients with locoregionally advanced nasopharyngeal carcinoma (NPC).

METHODS

From January 2000 to December 2006, 101 newly diagnosed elderly non-metastatic NPC patients (age≥65 years) who received cisplatin 3-weekly or weekly concurrent CRT with/without sequential chemotherapy were recruited. Each patient from the CRT group was matched to another patient treated with radiotherapy (RT) alone based on age, gender, pathological type, performance status, overall stage, stage method, Adult Comorbidity Evaluation-27 (ACE-27) score and RT technique, from the same institute and time period. We also recruited 101 young patients (age<65 years) as the referent group, which had been matched to the CRT group based on patient characteristics and treatment parameters. Treatment tolerability and toxicity were clarified, and treatment outcomes were calculated and compared among groups.

RESULTS

CRT was feasible in elderly NPC patients, while a concurrent regimen of weekly cisplatin was more tolerable. Grade≥3 acute toxicity in CRT group was similar with referent group, although it was significantly higher than the RT alone group (65.3% vs. 43.6%, P=0.002). Furthermore, patients with ACE-27 score≥2 in the CRT group had significantly higher severe acute toxicity and dose reduction. Survival was poorer in elderly patients than the referent group. Compared to RT alone, CRT significantly improved the 5-year overall survival (OS: 54.6% vs. 39.3%, P=0.009), cancer-specific survival (CSS: 56.6% vs. 42.7%, P=0.022), disease-free survival (DFS: 51.6% vs. 30.2%, P=0.028) and locoregional relapse-free survival (LRRFS: 78.4% vs. 52.2%, P=0.003), but not distant metastasis-free survival (DMFS: 69.6% vs. 63.6%, P=0.669). However, CRT did not significantly improve 5-year OS (43.6% vs. 27.3%, P=0.893) or CSS (43.6% vs. 34.1%, P=0.971) in elderly NPC patients with ACE-27 score≥2.

CONCLUSIONS

CRT is feasible and effective in elderly patients with locoregionally advanced NPC without severe comorbidities. CRT should be used under serious consideration and be further tested in elderly patients with severe comorbidities. As such, it is essential to perform a comprehensive evaluation of pretreatment comorbidity status for all elderly NPC patients.
