Complications, Mortality, and Functional Decline in Patients 80 Years or Older Undergoing Major Head and Neck Ablation and Reconstruction

State of Head and Neck Microvascular Reconstruction: Current and Future Directions

Since its inception, microvascular free tissue transfer has broadened possibilities for oncologic ablation and restoration of form and function. Developments throughout recent decades have resulted in increasing flap success rates and complexity. Advances in technology and knowledge gained from past experiences will continue to improve surgical efficiency, flap success rates, and ultimately, patient outcomes.

Predicting short-term treatment toxicity in head and neck cancer through a systematic review and meta-analysis

INTRODUCTION

Frailty is a recognized condition associated with poorer outcomes in patients with head and neck cancer (HNC). The objective of this study was to ascertain the prognostic significance of various frailty metrics on short-term treatment toxicity in patients with HNC undergoing curative-intent therapy.

MATERIALS AND METHODS

A systematic review was performed searching multiple databases. An inverse-variation, random-effects model was used to perform the meta-analysis to evaluate the prognostic significance of various frailty metrics on short-term treatment-related toxicity in this population.

RESULTS

A total of 292,560 patients with HNC originating from 36 observational studies were analyzed. The most frequently reported frailty metrics were the modified frailty index (mFI), Geriatric 8 questionnaire (G8), Adjusted Clinical Groups (ACG), Groningen Frailty Indicator (GFI), and comprehensive geriatric assessment (CGA). The overall prevalence of frailty using any metric in all included studies was 7.5 %. The combined odds ratio (OR) for short-term treatment toxicity using the mFI was 2.60 (95 % CI of 1.81-3.72), G8 2.69 (95 % CI 1.37-5.28), ACG 3.43 (95 %CI 2.52-4.67), GFI 2.71 (95 % CI 1.11-6.62), and CGA 3.36 (95 % CI 1.18-9.53). The association of frailty with short-term treatment toxicity using various frailty metrics was more pronounced in patients with upfront surgery (OR 3.00, 95 %CI of 2.35-3.81) compared to definitive (chemo)radiotherapy 2.64 (95 % CI 1.04-6.68).

DISCUSSION

Various frailty metrics exists in the HNC literature, with the most common being the mFI, G8, ACG, GFI, and CGA. Patients with HNC and frailty are more than twice as likely to suffer a short-term treatment-related toxicity when undergoing curative-intent HNC treatment than patients without frailty. This effect is more pronounced in patients undergoing upfront surgery.

Predicting Complications in Head and Neck Surgery: Comparing Calculators to Surgeons

Objectives: Surgical outcomes determine national ranking, reputation, and funding, and are often assessed with objective surgical risk calculators (SRCs). Surgeons' assessments are not considered. This study aims to determine if surgeons or SRCs are more accurate in predicting outcomes. Methods: This prospective cohort study identified a surgeon's assessment on a patient's risk preoperatively. The patient's risk was also calculated using the SRC. Predictions were compared to patient outcomes and to each other to assess whether surgeons or the SRC were more accurate. Results: Of the 101 patients included, 37 (36.6%) experienced a complication of any kind and 18 (17.8%) experienced a serious complication. Smoking resulted in a 2.49 times higher overall complication rate (P = .04). Laryngectomy patients experienced the highest rate of complications (P = .02) compared to those undergoing free flap reconstruction [odds ratio (OR) 0.9] or any other surgery (OR 0.26). Both surgeons and the American College of Surgeons (ACS) tool performed poorly on the prediction of the outcome of any complication, with a receiver operating characteristic (ROC) area under the curve (AUC) of 0.51 [95% confidence interval (CI): 0.39-0.62] and 0.58 (95% CI: 0.47-0.70), respectively, which was not statistically significant (P = .34). For the prediction of the outcome of serious complication, the AUC for surgeons and the ACS tool were 0.55 (95% CI: 0.41-0.69) and 0.60 (95% CI: 0.46-0.74), respectively, which was not statistically significant (P = .58). Conclusions: Neither validated risk calculators nor surgeons are accurate in predicting perioperative risk. The only risk factor that contributes to improving predictions for complications is preoperative smoking, although age and type of surgery are also significant predictors. Risk calculators may therefore not be appropriate metrics for assessing hospital performance. These findings can help guide preoperative counseling and may help in the development of more accurate predictive tools as the healthcare field continues to incorporate artificial intelligence into surgical planning.

Loss of Independence in Older Adults With Operable Oral Cavity Cancer: A Retrospective Cohort Study

OBJECTIVE

To ascertain the effect of curative-intent surgery on loss of independence (LOI) in patients with oral cavity squamous cell carcinoma (OCSCC).

STUDY DESIGN

Retrospective observational study of patients diagnosed from 2014 to 2021.

SETTING

Single tertiary care academic center. Patients having undergone curative-intent surgical treatment for OCSCC from 2014 to 2021 in the cancer registry.

METHODS

LOI as the primary outcome was measured based on a combination of decrease in activities of daily living (ADLs) and/or decline in mobility during treatment. Descriptive statistics were used to compare baseline demographics and multivariable logistic regression was used to assess the association between LOI and perioperative variables of interest.

RESULTS

Of the 180 patients included in this study, 139 (79%) were fully independent in ADLs/instrumental ADLs prior to surgery. The average age of the cohort was 74 with 49% males. Thirty-seven (21%) experienced a decline in mobility or increased care needs following surgery, and 18 (10%) experienced an independent decline in functional status. Increasing age, osseous flap reconstruction, high Charlson Comorbidity Index, and major postoperative adverse events were associated with LOI. Fifty-five percent of patients with LOI had recovered to baseline within 7 months from surgery. LOI was associated with poor treatment tolerance (odds ratio: 4.77, 95% confidence interval: 1.87-12.2) while adjusting for multiple confounders.

CONCLUSION

LOI is common in older adults undergoing curative-intent surgery for OCSCC and associated with poor treatment tolerance.

Survival Benefit from Cancer-Directed Surgery for Metastatic Head and Neck Cancer

OBJECTIVES

This study aimed to gather evidence for the survival benefit of cancer-directed surgery (CDS) in metastatic head and neck cancer (M1 HNC) and identify which patients will benefit most from CDS.

METHODS

Patients with M1 HNC were identified within the SEER database. According to whether received CDS, patients were divided into the CDS and non-CDS groups. The bias between the two groups was minimized using Propensity Score Matching (PSM), and the prognostic role of CDS was investigated using Kaplan-Meier analysis, log-rank test, and Cox proportional hazard models. The primary endpoint was overall survival (OS), and the secondary endpoint was cancer-specific survival (CSS).

RESULTS

A total of 3215 patients with M1 HNC were extracted, including 566 patients who received CDS that were 1:1 propensity score-matched with patients who did not receive CDS. In the matched dataset, the median OS and CSS in CDS groups were significantly higher than in non-CDS groups (OS: 19.0 vs. 9.0 months, p < 0.001; CSS: 21.0 vs. 9.0 months, p < 0.001). Meanwhile, multivariable Cox regression analysis also revealed that CDS was a favorable prognostic factor for both OS and CSS. Furthermore, subgroups of patients with M1 HNC (younger age, being married, grade I-II, oropharynx site, earlier T/N stage, radiotherapy) were inclined to benefit from CDS, while those patients who received chemotherapy failed to benefit from CDS.

CONCLUSIONS

This study indicated that CDS was associated with improved survival in M1 HNC, especially for those subpopulations that benefit more from CDS treatment.

Association of Age and Frailty With 30-Day Outcomes Among Patients Undergoing Oral Cavity Cancer Surgery

OBJECTIVE

To evaluate the impact of age and frailty on 30-day outcomes following surgery for oral squamous cavity carcinoma (OSCC).

STUDY DESIGN

Retrospective cross-sectional analysis.

SETTING

American College of Surgeons' National Quality Improvement Program (NSQIP) database.

METHODS

Patients who underwent OSCC resection were queried via NSQIP (2015-2020). Cases were stratified by age (18-65, 65-75, and older than 75) as well as by modified frailty index scores (mFI 0, mFI 1, and mFI 2+) for comparative analyses. Univariate and multivariable analyses were conducted to examine demographics, perioperative outcomes, and 30-day postoperative adverse events.

RESULTS

A total of 3238 patients who underwent OSCC surgery were identified and categorized as nongeriatric ("NGA," age 18-65), younger geriatric ("YGA," age 65-75), and older geriatric ("OGA," age >75) adults. Compared to NGA, geriatric patients had higher the American Society of Anesthesiologists classification, higher modified frailty index scores, and more comorbidities such as hypertension, congestive heart failure, chronic obstructive disease, and diabetes (p < .001). YGAs and OGAs were also less likely to undergo neck dissection (p < .001), composite resection (p = .006), and free flap reconstruction compared to NGAs (p < .001). When controlling for confounders, age was not independently associated with an increased risk of poor outcomes. On the other hand, frailty was found to be independently associated with a higher risk of adverse events (odds ratio: 1.40 [1.15-1.70], p < .001 for mFI 1, odds ratio: 1.45 [1.04-2.02], p = .027 for mFI 2+).

CONCLUSION

A higher mFI score, not older age, is associated with an increased risk of 30-day complications following OSCC surgery.

Survival and prognosis of surgical head and neck cancer patients aged 80 years and older

Introduction

Elderly patients (≥80 years of age) with head and neck cancer (HNC) can prove a management challenge due to concerns regarding their suitability for surgery. This study aims to describe the characteristics and outcomes of elderly patients undergoing HNC surgery.

Methods

A retrospective review of elderly patients undergoing HNC surgery was conducted. Demographics, comorbidities, tumor characteristics, surgical procedure type, postoperative complications, and disposition were reviewed. Overall survival (OS) in the elderly cohort was compared against younger patients (<80 years).

Results

A total of 595 patients were included, of whom 86 were aged >80 years (71% male; mean age 84.8, range 80.0-98.8 years). The overall complication rate was 43%. When compared with younger patients (n = 509), elderly patients had reduced OS (risk ratio: 2.0, 95% CI: 1.3-3.2), higher 90-day mortality (8.1% vs. 2.3%, p = .005), and lower 5-year survival (43.5% vs. 64.1%, p < .001). However, survival was comparable to age-specific life expectancy. There was no difference in OS, 90-day mortality, and 5-year survival when comparing >85 (n = 33) and 80-85 (n = 53) age groups.

Conclusions

Chronological age alone should not negatively influence decision-making in HNC surgery the elderly. With careful preoperative selection and optimization, surgery can be performed at acceptable risk with good outcomes in elderly patients.

Management of Older Patients with Head and Neck Cancer: A Comprehensive Review

The projected increase in life expectancy over the next few decades is expected to result in a rise in age-related diseases, including cancer. Head and neck cancer (HNC) is a worldwide health problem with high rates of morbidity and mortality. In this report, we have critically reviewed the literature reporting the management of older patients with HNC. Older adults are more prone to complications and toxicities secondary to HNC treatment, especially those patients who are frail or have comorbidities. Thus, this population should be screened prior to treatment for such predispositions to maximize medical management of comorbidities. Chronologic age itself is not a reason for choosing less intensive treatment for older HNC patients. Whenever possible, also older patients should be treated according to the best standard of care, as nonstandard approaches may result in increased treatment failure rates and mortality. The treatment plan is best established by a multidisciplinary tumor board with shared decision-making with patients and family. Treatment modifications should be considered for those patients who have severe comorbidities, evidence of frailty (low performance status), or low performance status or those who refuse the recommendations of the tumor board.

Clinical comparison of superior thyroid artery perforator flap and sternocleidomastoid myocutaneous flap for intraoral reconstruction

The aim was to evaluate the techniques and outcomes of superior thyroid artery perforator flaps (STAPF) for intraoral reconstruction and to compare them with those of the sternocleidomastoid myocutaneous flap (SCMMF). The cases of 43 patients who underwent reconstruction with either a SCMMF or STAPF for the repair of a medium-sized intraoral defect, between January 2013 and December 2020, were reviewed retrospectively. Although both flaps are based on the superior thyroid artery, their specific harvesting techniques largely differ. All SCMMF (n = 23) were superiorly-based rotational flaps with myocutaneous designs. The STAPF cases (n = 20) included 18 septocutaneous flaps and two chimeric flaps. The flap size was larger in the STAPF group (P = 0.008), while incomplete level IIB dissection (oncological safety) was more frequent in the SCMMF group (P = 0.002). The flap necrosis rate was lower in the STAPF group (STAPF 15% vs SCMMF 34.8%, though this was not statistically significant). Cox multivariate analysis showed that the postoperative flap outcome (total flap necrosis vs flap survival; hazard ratio 27, 95% confidence interval 2.149-336.05; P = 0.001) and complications (excluding fistula) (hazard ratio 14, 95% confidence interval 1.314-142.767; P = 0.029) were associated with overall patient survival. Both speech (P < 0.001) and neck mobility (P < 0.001) functions were superior with STAPF reconstruction. Compared with the traditional SCMMF, the STAPF was found to have a lower necrosis rate with uncompromised oncological safety during harvesting. The STAPF is a good alternative for the repair of medium-sized head and neck defects.

Emerging Concepts Impacting Head and Neck Cancer Surgery Morbidity

All treatment modalities for head and neck cancer carry with them a risk of adverse events. Head and neck surgeons are faced with significant challenges to minimize associated morbidity and manage its sequelae. Recognizing situations in which a surgical complication is an adverse event inherent to the procedure can alleviate the psychologic impact a complication might have on the treatment team and minimize external and internal pressures. Focusing on the complications that can be effectively modified, future complications can be avoided. Also, some surgical morbidities may not be preventable, necessitating the option to reconsider whether the incidents should be labeled toxic reactions rather than a complication. This discussion highlights some of the areas in which additional research is needed to achieve the goal of minimizing the impact of surgical morbidity.

Head and neck cancer surgery in elderly patients: the role of frailty assessment

OBJECTIVES

To study whether any risk model, frailty index, patients' comorbidities, or demographic characteristics correlate with postoperative morbidity in elderly patients who underwent surgery for head and neck cancer (HNC). A secondary objective was to compare between frailty indexes that are used at our medical center.

METHODS

A retrospective analysis of head and neck cancer patients operated between 2007 and 2021 was performed.

RESULTS

One hundred and fifteen patients were included and divided into three age groups: 50-69 years, 70-79 years and ≥ 80 years. Although most elderly patients had a significantly higher rate of comorbidities and lower Norton scores, no statistically significant difference was found between the groups in postoperative morbidity rates, intensive care unit (ICU) or internal medicine department admissions, re-hospitalization in 1-3 months, and in falling risk (MFS-Morse Fall Scale). On multivariate analysis there was a positive correlation between preoperative cerebrovascular accident (CVA), dementia, and cardiac arrhythmias, and the probability for developing postoperative complication. The latter findings were not related to the patients' age.

CONCLUSIONS

In this study, we did not find higher postoperative morbidity rates among elderly population in comparison to younger age groups, and therefore, our current evaluation system could not assist in identifying elderly at risk. However, prediction of operative risk based on physiologic reserve or frailty is an important tool in the evaluation of elderly head and neck cancer patients. Future studies are needed to assess the role of frailty index in the elderly head and neck cancer population.

Frailty as a predictor of adverse outcomes in head and neck reconstruction: A systematic review

BACKGROUND

Frailty has been shown to adversely impact outcomes in a number of surgical disciplines. In head and neck reconstructive surgery, frailty may represent a significant risk factor in predicting post-operative outcomes due to the common characteristics of the patient population undergoing these procedures.

OBJECTIVES

To summarize the available evidence about frailty as a predictor of post-operative complications, length of hospital stay and quality of life in patients undergoing head and neck reconstructive surgery.

STUDY DESIGN

Systematic Review.

METHODS

The study protocol was registered with PROSPERO, registration CRD42022302899. Methodology was in keeping with the PRISMA Guidelines for Systematic Reviews. MEDLINE, SCOPUS, EMBASE, Web of Science and CENTRAL were the databases searched. Qualitative synthesis of the included studies was carried out, and quality assessment was performed.

RESULTS

Nine studies that reported data on 10,457 patients undergoing reconstruction of the head and neck were included in the review. A number of different tools were used to assess frailty, with the modified frailty index being the most frequently used. In total, 8 studies reported increased rates of complications in patients with increased levels of frailty, irrespective of the frailty tool used, with varied levels of statistical significance across the studies.

CONCLUSION

An association is observed between increased rates of perioperative complications and increased levels of frailty in patients undergoing head and neck reconstruction. Frailty tools may represent a useful method to risk stratify patients undergoing reconstructive head and neck surgery.

Assessing Risk of Severe Complications after Endoscopic Transnasal Transsphenoidal Surgery: A Comparison of Frailty, American Society of Anesthesiologists, and Comorbidity Scores

Objective  This study aimed to improve age-independent risk stratification for patients undergoing endoscopic transnasal transsphenoidal (TNTS) approach to pituitary mass resection by investigating the associations between frailty, American Society of Anesthesiologists (ASA), and comorbidity scores with severe complications following TNTS. Design  This study is a retrospective review. Setting  This review was conducted utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Participants  A total of 680 cases of TNTS identified from 2010 to 2013 were included in this study. Main Outcome Measures  The modified frailty index (mFI) was calculated to quantify frailty. ASA and Charlson's comorbidity index (CCI) scores were obtained as physiologic status and comorbidity-based prognostic markers. Severe complications were separated into intensive care unit (ICU)-level complications, defined by Clavien-Dindo grade IV (CDIV) criteria, and mortality. Results  Overall, 24 CDIV complications (3.5%) and 6 deaths (0.9%) were recorded. Scores for mFI ( p  = 0.01, R ²  = 0.97) and ASA ( p  = 0.04., R ²  = 0.87) were significantly correlated with CDIV complications. ASA scores were significantly correlated with mortality ( p  = 0.03, R ²  = 0.87), as well as independently associated with CDIV complication by multivariable regression models (odds ratio [OR] = 2.96, 95% confidence interval [CI]: 1.35-6.83, p  < 0.01), while mFI was not. CCI was not significantly associated with CDIV complications or mortality. A multivariable regression model incorporating ASA had a lower Akaike's Information Criteria (AIC; 188.55) than a model incorporating mFI (195.99). Conclusion  Frailty and physiologic status, as measured by mFI and ASA scores respectively, both correlate with ICU-level complications after TNTS. ASA scores demonstrate greater clinical utility than mFI scores; however, as they are more easily generated, uniquely correlated with mortality and independently associated with ICU-level complication risk on multivariable regression analysis.

Temporal trends in oropharyngeal cancer incidence, survival, and cancer-directed surgery among elderly Americans

OBJECTIVE

This study assesses longitudinal epidemiologic trends in the oldest head and neck cancer (HNC) patients, comparing the oropharynx to other mucosal HNC sites.

MATERIALS AND METHODS

Using data from the Surveillance, Epidemiology, and End Results database, trends in incidence, two-year cancer specific mortality, and percent of cases recommended for and which received surgery from 2000 to 2018 in patients ages ≥85 years were assessed using Joinpoint analysis by HNC site. Trends were quantified as annual percentage change (APC) with 95% confidence intervals (CI).

RESULTS

Among older adults, oropharyngeal cancer (OPC) incidence increased (APC = 1.80% [95% CI: 0.94-2.67]), while mortality decreased (APC = -2.01% [95% CI: -3.26--0.74]) from 2000 to 2018. At other mucosal HNC sites, incidence and mortality remained stable. Percentage of patients who received surgery significantly changed for oropharyngeal (APC = -15.34% from 2000 to 2005 [95% CI: -24.37 to -4.79]) and laryngeal (APC = -4.61% from 2000 to 2008 [95% CI -8.28 to -0.80]) cancers. Trends in recommendation for surgery varied by site with significant decreases at the larynx, oral cavity, and oropharynx.

CONCLUSION

OPC incidence is increasing among the oldest HNC patients. An increasing proportion of HPV-associated tumors could account for associated mortality improvement. There has been a shift towards non-surgical therapy possibly due to known favorable response of HPV-associated OPC to radiation therapy and/or poor surgical candidacy in this age group. The evolving treatment approach has not been detrimental to population-level survival outcomes, but optimal treatment has yet to be established. Future studies with pathologically confirmed HPV status are needed to better understand older adult OPC burden.

Predictors of Health Care Utilization Following Major Head and Neck Oncologic Surgery in Older Patients

OBJECTIVE

To identify patient factors in older patients associated with making posttreatment visits in the first year after major head and neck oncologic surgery.

STUDY DESIGN

Retrospective cohort study.

SETTING

Academic institution.

METHODS

Patients aged ≥60 years who underwent a neck dissection with or without a free flap reconstruction were retrospectively analyzed. Data collected included patient demographics, comorbidities, social variables, perioperative course, and clinical visits.

RESULTS

Within a 1-year postoperative period, the 181 patients in our cohort had a mean ± SD 6.37 ± 3.6 postoperative clinic visits; 70% attended at least 4 visits. Multivariable regression analysis showed a significant association with distance closer to the hospital (P = .013): for every 10-mile increase in distance, the number of visits decreased by 0.15 (SE = 0.06). Additionally, receiving adjuvant radiation therapy (P = .0096) demonstrated significant associations: when compared with no adjuvant therapy, radiation therapy had on average 1.5 (SE = 0.56) more visits, and chemoradiation had 0.04 (SE = 0.73) more visits.

CONCLUSION

Older patients who undergo major head and neck oncology surgery are more likely to attend posttreatment visits in the 1 year following surgery if they are discharged home rather than to a skilled nursing facility, live closer to the hospital, and undergo adjuvant radiation therapy.

The impact of frailty on adjuvant treatment in patients with head and neck free flap reconstruction-A retrospective study using two independent frailty scores

OBJECTIVES

Reconstructive surgery may result in prolonged postoperative recovery, especially in frail patients, which in turn may impact delivery of adjuvant therapy. To date, no studies have investigated potential associations between frailty and adjuvant treatment delivery after reconstructive surgery. We examine the impact of frailty on time to initiation, duration, and completion of adjuvant treatment after reconstructive surgery for head and neck cancers (HNCs).

METHODS

A retrospective review of patients who underwent free flap reconstruction for HNC at a single institution from 2015 to 2021 and received adjuvant radiation was performed. Frailty was assessed using two independent scales: the 11-item modified frailty index (mFI) score and binary Johns Hopkins Adjusted Clinical Groups (ACG) frailty indicator. Timely adjuvant initiation (within six weeks of surgery), duration of adjuvant treatment, and completion were compared between frail and non-frail patients.

RESULTS

Of the 163 patients included for analysis, 52 (31.9%) were identified as frail by the ACG indicator and 24 (14.7%) were identified as frail with an mFI score ≥ 3. Frail patients (mFI score ≥ 3) were significantly less likely than non-frail patients to initiate adjuvant treatment within six weeks (OR:0.21, CI:0.04-0.85, p = 0.046). Frailty designated by either frailty scale was not significantly associated with adjuvant treatment duration. Likelihood of adjuvant treatment completion was significantly lower for frail compared to non-frail patients by both scales: ACG indicator (OR 0.02, CI:9.05 × 10^-4-0.25, p = 0.007) and mFI score ≥ 3 (OR:0.01, CI:6.85 × 10^-4-0.13, p = 0.007).

CONCLUSIONS

Frailty is associated with decreased likelihood of timely adjuvant treatment initiation and completion in patients with HNCs after free flap reconstruction.

Frailty Assessed with FRAIL Scale and G8 Questionnaire Predicts Severe Postoperative Complications in Patients Receiving Major Head and Neck Surgery

Introduction: Frailty represents a complex geriatric syndrome associated with elevated rates of postoperative complications as shown for several malignant entities, including head and neck cancer. A specific screening instrument to assess frailty in head and neck patients does not exist. Both the FRAIL Scale and the G8 questionnaire are well-established and easy to use as screening tools. The present study’s aim was to assess the potential of frailty screening to predict postoperative complications in head and neck patients prior to surgery. Patients and methods: We recorded demographic data, pre-existing medical conditions and clinical characteristics in a prospective cohort of 104 head and neck cancer patients undergoing major head and neck surgery and assessed frailty prospectively on the day of admission utilizing the G8 questionnaire and the FRAIL Scale. We analyzed the link between occurrence of postoperative complications up to the twenty-first postoperative day and age, frailty and other covariates using χ² tests and receiver operating characteristic (ROC) curves. Results: There was no significant correlation between patients’ pre-existing medical conditions and postoperative complications. Whereas chronological age alone did not predict the occurrence of postoperative complications, frailty posed the highest risk for complications. Frailty according to either the G8 questionnaire or the FRAIL Scale predicted occurrence of complications with an area under the curve (AUC) of 0.64 (p = 0.018) and 0.62 (p = 0.039) and severe complications with an AUC of 0.72 (p = 0.014) and 0.69 (p=0.031), respectively. Neither frailty score correlated with age or with each other. Conclusion: Prospective screening using the FRAIL Scale or the G8 questionnaire reliably detected frailty in our sample group. Frailty is linked to increased risk of postoperative complications. The correct prediction of severe postoperative complications as shown identifies vulnerable cases and triggers awareness of potential complications. Anticipating risk allows for a more comprehensive view of the patient and triggers decision making towards risk adjustment, and therefore a selective view of alternative treatment modalities.

Worse cranial neurosurgical outcomes predicted by increasing frailty in patients with interhospital transfer status: Analysis of 47,736 patients from the National Surgical Quality Improvement Program (NSQIP) 2015-2019

INTRODUCTION

With limited healthcare resources and risks associated with unwarranted interhospital transfers (IHT), it is important to select patients most likely to have improved outcomes with IHT. The present study analyzed the effect of IHT and frailty on postoperative outcomes in a large database of patients who underwent cranial neurosurgical operations.

METHODS

The National Surgical Quality Improvement Program (NSQIP) database was queried for patients who underwent cranial neurosurgical procedures (2015-2019, N = 47,736). Baseline demographics, clinical characteristics, and outcome variables were compared between IHT and n-IHT patients. Univariate and multivariable analyses analyzed the effect of IHT status on postoperative outcomes and the utility of frailty (modified frailty index-5 [mFI-5] stratified into "pre-frail, "frail", and "severely frail") as a preoperative risk factor. Effect sizes from regression analyses were presented as odds ratio (OR) with associated 95% confidence intervals (95% CI).

RESULTS

Of 47,736 patients with cranial neurosurgical operations, 9612 (20.1%) were IHT. Patients with IHT were older, frailer, with a higher rate of functional dependence. In multivariable analysis adjusted for baseline covariates, IHT status was independent associated with 30-day mortality (OR: 2.0, 95% CI: 1.2-3.6), major complication (OR: 1.5, 95% CI: 1.1-2.1), extended hospital length of stay (eLOS) (OR: 3.8, 95% CI: 3.6-4.1), and non-routine discharge disposition (OR: 2.4, 95% CI: 1.8-3.2) (all p < 0.05). Within the IHT cohort, increasing frailty ("pre-frail", "frail", "severely frail") was independently associated with increasing odds of 30-day mortality (OR: 1.4, 1.9, 3.9), major complication (OR: 1.4, 1.9, 3.3), unplanned readmission (OR: 1.1, 1.4, 2.1), reoperation (OR: 1.3, 1.5, 1.9), eLOS (OR: 1.2, 1.3, 1.5), and non-routine discharge (OR: 1.4, 1.9, 4.4) (all p < 0.05). All levels of frailty were more strongly associated with postoperative outcomes than chronological age.

CONCLUSIONS

This novel analysis suggests that patients transferred for cranial neurosurgery operations are significantly more likely to have worse postoperative health outcomes. Furthermore, the analysis suggests that frailty (as measured by mFI-5) is a powerful independent predictor of outcomes in transferred cranial neurosurgery patients. The findings support the use of frailty scoring in the pre-transfer and preoperative setting for patient counseling and risk stratification.

"Age is just a number"; frailty as a marker of peri-operative risk in head and neck surgery: Systematic review and meta-analysis

BACKGROUND

Frailty refers to a patient's reduced capacity to withstand stressors due to a reduction in physiologic reserves. We assessed the impact of frailty on outcomes following head and neck surgery.

METHODS

We performed a systematic review in accordance with the PRISMA guidelines. Meta-analysis was performed using the Mantel-Haenszel method.

RESULTS

Fourteen studies incorporating 182 059 patients were included in qualitative synthesis with 15 953 (8.8%) of patients deemed as frail. Meta-analysis incorporating nine studies demonstrated that frailty is associated with an increased 30 day postoperative morbidity (OR 2.74; 95% CI 1.98-3.80; p < 0.01) and meta-analysis with six studies suggested increased 30-day mortality (OR 2.94; 95% CI 2.62-3.31; p < 0.01). Preliminary meta-analyses between two and five studies suggested that frail patients had reduced overall survival and were more likely to be discharged to a nonhome location or readmitted within 30 days.

CONCLUSIONS

Frailty appears to be associated with poor short-term outcomes following head and neck surgery and may improve understanding of an individual patient's peri-operative risk.

Postoperative and 1-Year Functional Outcomes After Free Flap Surgery Among Patients 80 Years or Older

OBJECTIVE

To evaluate the postoperative and 1-year functional outcomes after free flap surgery among patients ≥80 years old.

STUDY DESIGN

Retrospective chart review.

SETTING

Single tertiary care center.

METHODS

We conducted a retrospective review of 596 patients who underwent head and neck ablation and reconstruction with free tissue over a 7-year period. Patients ≥80 years of age were included.

RESULTS

Fifty patients were ≥80 years old, with an average age of 83.7 years. Ninety-day mortality was 12.0%, and those who died were of older age (87.5 vs 83.1 years, P = .036). Prior radiation therapy (odds ratio, 6.8 [95% CI, 1.1-42.7]) and a Charlson Comorbidity Index ≥3 (odds ratio, 10.0 [95% CI, 1.5-67.0]) were associated with an increased risk of 90-day mortality. Overall 21 (42.0%) patients experienced a 30-day complication; 7 (14.0%) were readmitted within 30 days; and 5 (10.0%) underwent additional flap-related operations. Flap failure occurred in 2 (4.0%) patients. Before surgery, 45 (90%) patients were living independently or within assisted living; among these, 19.5% declined to dependent functional status at 90-day follow-up. At 90 days, 2 (8.3%) of 24 patients remained tracheostomy dependent, and 20 (66.7%) of 30 patients required feeding tube supplementation. Among 42 patients, 36 (85.7%) had unrestricted or modified oral diets at 90 days. Charlson Comorbidity Index ≥2 was associated with an increased risk of 1-year mortality (odds ratio, 5.1 [95% CI, 1.4-18.6]).

CONCLUSION

The potential for functional decline and risk of 90-day mortality should be discussed with patients aged ≥80 years.

[Frailty in Head and Neck Oncology]

Since treatment of elderly patients with head and neck cancer is often challenging due to preexisting comorbidities, continuous efforts are required to raise awareness for frailty, which is a multidimensional state of diminished physiologic reserve resulting in decreased resiliency and increased vulnerability to stressors. Frailty is a predictor of poor clinical outcomes in head and neck cancer patients, but until now there is no standardization of frailty assessment. Pretherapeutic frailty assessment among head and neck cancer patients should be incorporated into routine multidisciplinary management to predict adverse outcomes and tailor a personalized treatment. This article would like to explain the complex syndrome frailty and its importance for head and neck oncology.

Outcomes following head and neck cancer surgery among older adults as determined by an electronic geriatric assessment

PURPOSE

Older adults with head and neck cancer have increased postoperative complications, longer hospital stays, and higher rates of mortality. Geriatric assessment (GA) provides a measure of overall health status and is preferable to using age alone for assessing fitness for surgery. We sought to determine whether a patient's frailty as determined by a novel electronic GA is associated with outcomes after head and neck cancer (HNC) surgery.

METHODS

We conducted a retrospective review of 159 patients aged 75 and older referred to the Geriatrics Service at Memorial Sloan Kettering Cancer Center for pre-operative evaluation prior to undergoing HNC surgery. All patients completed the electronic Rapid Fitness Assessment (eRFA) within 60 days prior to surgery. The accumulated geriatric deficit (AGD) score includes twelve domains from the eRFA with a point assigned for each domain in which there is a deficit and a final point related to comorbidities. Three other metrics were individually assessed: age, Karnofsky Performance Scale (KPS), and number of comorbidities. We utilized multivariable linear regression and t-tests to determine whether frailty is associated with longer length of hospital stay, 30-day intensive care unit (ICU) admission, and 30-day and 90-day postoperative mortality.

RESULTS

Patients with a higher AGD score spent more time in the hospital post-operatively (1.0 day increase per unit increase in AGD; 95% CI: 0.21-1.9; p = 0.015). Lower KPS was also associated with statistically significant longer length of stay (-2.70 day change per increasing index KPS; 95% CI: -4.30 - -1.00; days; p = 0.002), while age and comorbidity were not found to be statistically associated with length of stay. Higher AGD score remained significantly associated with longer length of stay on multivariable analysis (0.93 day increase per unit increase in AGD; 95% CI 0.15-1.71; p = 0.019). AGD was the only metric associated with increased risk of ICU admission (6.6 vs 5.0 geriatric deficits for those admitted vs not admitted to ICU; p = 0.024).

CONCLUSIONS

Frailty is associated with increased length of hospital stay and ICU admission in older adults with HNC undergoing surgery. GA can be used to counsel patients on the expected postoperative course.

Failure of preoperative co-morbidity indices to predict the successful use of the composite scapula free flap for maxillofacial reconstruction in patients with significant medical co-morbidities

The aim of this study was to evaluate the accuracy of validated preoperative patient co-morbidity assessments, including the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), with the use of the composite scapula free flap (CSFF) in maxillofacial reconstruction in patients with significant medical co-morbidities. A retrospective cohort review was performed at an academic institution, covering the period from July 2010 through January 2019. All patients who underwent reconstruction with a CSFF with significant medical co-morbidities were included. Co-morbidity assessments and risk factors were analyzed by comparing predicted versus observed early and late medical and surgical complications. Forty-five patients met the inclusion criteria. The surgical complication rate was 47%; the medical complication rate was 38%. Over 90% of patients returned to successful function at 3 months post-surgery. The ACS-NSQIP prediction of complications ranged from 58% to 75% for accuracy, 76% to 100% for sensitivity, and 50% to 69% for specificity. The prediction of a serious complication was statistically significant in patients with a Charlson Co-morbidity Index ≥7. Age ≥80 years did not significantly increase the risk of a serious complication (P = 0.23). The ACS-NSQIP failed to predict the successful use of the CSFF for patients with significant co-morbidities undergoing maxillofacial reconstruction. The selection of patients who will tolerate complex reconstruction cannot be based solely on co-morbidity charts and standardized preoperative indices.

The Utility of Comorbidity Indices in Assessing Head and Neck Surgery Outcomes: A Systematic Review

OBJECTIVE

To evaluate the utility of comorbidity index (CI) scores in predicting outcomes in head and neck surgery (HNS). The CIs evaluated were the Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Index (ECI), Kaplan-Feinstein Index (KFI), American Society of Anesthesiologists Physical Status (ASA-PS), Adult Comorbidity Evaluation-27 (ACE-27), National Cancer Institute Comorbidity Index (NCI-CI), and the Washington University Head and Neck Comorbidity Index (WUHNCI).

METHODS

We report a systematic review according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Electronic databases (PubMed, Cochrane, and Embase) and manual search of bibliographies identified manuscripts addressing how CI scores related to HNS outcomes.

RESULTS

A total of 116 studies associated CI scores with HNS outcomes. CIs were represented in the literature as follows: ASA-PS (70/116), CCI (39/116), ACE-27 (24/116), KFI (7/116), NCI-CI (3/116), ECI (2/116), and WUHNCI (1/116). The most frequently cited justification for calculating each CI (if provided) was: CCI for its validation in other studies, ACE-27 for its utility in cancer patients, and ECI for its comprehensive design. In general, the CCI and ACE-27 were predictive of mortality in HNS. The ECI was most consistent in predicting >1-year mortality. The ACE-27 and KFI were most consistent in predicting medical complications.

CONCLUSION

Despite inconsistencies in the literature, CIs provide insights into the impact of comorbidities on outcomes in HNS. These scores should be employed as an adjunct in the preoperative assessment of HNS patients. Comparative studies are needed to identify indices that are most reliable in predicting HNS outcomes.

Age and Comorbidities Impact Medical Complications and Mortality Following Free Flap Reconstruction

OBJECTIVE

Determine if age correlated with surgical or medical complications following head and neck free flap reconstruction.

STUDY DESIGN

Retrospective review of prospectively collected databases.

METHODS

Patients undergoing head and neck free flap reconstruction at three tertiary care institutions were included (n = 1972). Cohorts were based on age (<65, 65-75, 75-85, and >85). Outcomes reviewed operative duration, length of stay, surgical complications (free flap failure, fistula, hematoma, dehiscence, and infection), and medical complications (thromboembolism, stroke, cardiac, and pulmonary).

RESULTS

Anatomic site (P < .0001) and donor site varied by age (P < .0001). There was no difference in operative duration (P = .3) or length of hospitalization (P = .8) by age. The incidence of medical complications increased with increasing age. Pulmonary complication rates: <65 (3.9%), 65 to 75 (4.8%), 75 to 85 (7.1%), and >85 (11%) (P = .02). Cardiac complication rates: <65 (2.0%), 65 to 75 (7.3%), 75 to 85 (6.1%), and >85 (16.4%) (P < .0001). Mortality increased with age: <65 (0.4%), 65 to 75 (0.8%), 75 to 85 (1.1%), and >85 (4.1%) (P < .003). Medical complications correlated with mortality rates: pulmonary (3.5% vs. 0.6%; OR: 5.5; 95% CI: 1.5-20.0; P = .004); cardiac (3.3% vs. 0.6%; OR: 6.0; 95% CI: 1.6-21.8; P = .002); thromboembolism (4.6% vs. 0.7%; OR: 7.3; 95% CI: 1.6-33.6; P = .003); stroke (42% vs. 0.5%; OR: 149; 95% CI: 40-558; P < .0001); and sepsis (5% vs. 0.7%; OR 7.5; 95% CI: 1.0-60.5; P = .03). Age did not correlate with free flap success (P = .5), surgical complications (hematoma, P = .33; fistula, P = .23; infection, P = .07; and dehiscence, P = .37), or thirty-day readmission (P = .3).

CONCLUSION

Following free flap reconstruction, patient age did not correlate with development of a surgical complication. Patient age did correlate with development of a medical complication. Postoperative medical complications were found to correlate with perioperative mortality.

The role of age in treatment decisions for oral cavity squamous cell carcinoma: Analysis of the National Cancer Database

BACKGROUND

The number of elderly patients with oral squamous cell carcinoma (OCSCC) is increasing as the elderly population increases. Unfortunately, evidence to guide the management of these patients is lacking.

METHODS

Patients with OCSCC identified from the National Cancer Database (NCDB) were stratified into age-based cohorts. Demographics, comorbidities, and treatment patterns were analyzed. Patients were stratified into early stage (Stage I/II) and advanced stage (Stage III/IV) disease. The likelihood of receiving multimodality therapy by age was calculated using multinomial logistic regression for each stratum while controlling for potential confounders. Cox proportional hazard regression was used to calculate 5-year mortality risk while controlling for potential confounders.

RESULTS

Surgery alone or palliative options were offered to older patients more frequently. After controlling for confounders, older patients were less likely to receive multimodality therapy for both early stage and advanced stage disease. Patients with advanced disease across all age cohorts had improved 5-year survival with surgery and adjuvant therapy.

CONCLUSION

Our analyses suggest that elderly patients have unique demographic and pathologic features. They frequently receive less treatment than similarly staged younger patients, yet they benefit from multimodality therapy when feasible. These data suggest an urgent need to critically appraise the care of elderly OCSCC patients within the broader context of their individual comorbidity burden, functional status, and treatment goals.

A novel application of superior thyroid artery perforator flaps for medium-sized intraoral reconstructions: Retrospective analysis of 12 cases

BACKGROUND

To describe the indications, technique, and preliminary experience in the application of the superior thyroid artery perforator flap (STAPF) for the reconstruction of various medium-sized intraoral defects.

METHODS

From September 2018 to September 2019, 12 consecutive cases of oral squamous cell carcinoma underwent reconstruction with a STAPF. Clinical details were collected, and postoperative function was analyzed.

RESULTS

The venous drainage of the STAPF is variable with drainage into the internal jugular vein in six cases, into both the internal and external jugular veins in four cases, and into the external jugular vein in two cases. Ten cases were harvested as pedicled flaps, while two cases required a venous anastomosis due to inadequate length of the venous pedicle. Ten flaps survived completely, whereas two flaps had partial necrosis that ultimately resolved with secondary healing.

CONCLUSIONS

STAPF is a reliable method for the reconstruction of medium-sized intraoral defects.

Methods for frailty screening and geriatric assessment in older adults with cancer

PURPOSE OF REVIEW

This review highlights the latest development in the use of geriatric assessment(GA) and frailty assessment for older adults with cancer.

RECENT FINDINGS

From 2019, there were six large randomized controlled trials (RCTs) completed of GA for older adults with cancer, as well as several studies of frailty screening tools.

SUMMARY

The findings in this review highlight the benefits of implementing GA, followed by interventions to address the identified issues (GA -guided interventions). Four of six RCTs that implemented GA for older adults with cancer showed positive impact on various outcomes, including treatment toxicity and quality of life. GA implementation varied significantly between studies, from oncologist acting on GA summary, geriatrician comanagement, to full GA by a multidisciplinary team. However, there were several barriers reported to implementing GA for all older adults with cancer, such as access to geriatrics and resource issues. Future research needs to elucidate how to best operationalize GA in various cancer settings. The authors also reviewed frailty screening tools and latest evidence on their use and impact.

Longitudinal Assessment of Frailty and Quality of Life in Patients Undergoing Head and Neck Surgery

OBJECTIVE

To understand changes in frailty and quality of life (QOL) in frail versus non-frail patients undergoing surgery for head and neck cancer (HNC).

METHODS

Prospective cohort study of patients (median age 67 (50, 88)) with HNC undergoing surgery from December 2011 to April 2014. Fried's Frailty Index, Vulnerable Elders Survey (VES-13), and comprehensive QOL assessments (EORTC QLQ-C30 and HN35) were completed at baseline and 3, 6, and 12-month post-operative visits. Change in frailty and QOL over time was compared between frailty groups (non-frail (score 0), pre-frail (score 1-2), and frail (score 3-5)) using a mixed effects model. Predictors of long-term elevated frailty (12 months > baseline) were analyzed using logistic regression.

RESULTS

The study had 108 patients classified as non-frail (47%), 104 pre-frail (mean (SD) 1.3 (0.4), 45%), and 17 frail (3.4 (0.6); 7%). Frailty score decreased significantly for frail patients 3 months post-operatively (2.1 (1.0); P = .002) and remained significantly lower than baseline at 6 and 12 months (2.1 (1.4); P = .0008 and 2.2 (1.5); P = .005, respectively) while frailty score increased for non-frail patients at 3 months (1.1 (1.0); P < .001) and then decreased. Forty-eight patients (21%) had long-term elevated frailty, with baseline frailty and marital status identified as predictors on univariate analysis. The frail population had significantly worse QOL scores at baseline, which persisted 12 months post-operatively.

CONCLUSIONS

Frail patients demonstrate a decrease in frailty score following surgical treatment of HNC. Frail patients have significantly worse QOL scores on longitudinal assessment and would benefit from supportive services throughout their care.

Change in Age at Diagnosis of Oropharyngeal Cancer in the United States, 1975-2016

Simple Summary

While previous studies have suggested that HPV-associated head and neck cancer (HNC) is mostly in the younger population, we found that in the last 40 years, the mean age at diagnosis of oropharyngeal cancer has been 60.3 years. We found that after an initially decrease leading up to the early 2000s, there has been a steady increase in age at diagnosis of oropharyngeal cancer since 2002. For non-oropharyngeal HNC, mean age at diagnosis has steadily increased throughout the last four decades. Finally, we found that age at diagnosis of HNC is higher among females in general, and lowest among blacks.

Abstract

The emergence of the human papillomavirus (HPV) as the primary etiology of oropharyngeal cancer has changed head and neck cancer (HNC) epidemiology. This study described change in the age at diagnosis of oropharyngeal and non-oropharyngeal HNC in the United States in the last four decades. Using a retrospective cohort analysis, the Surveillance, Epidemiology, and End Results dataset from 1975 to 2016 was queried for eligible adult cases of HNC, grouped as oropharyngeal (n = 31,702) versus non-oropharyngeal (n = 87,108). Age at diagnosis was compared by gender (female, male) using independent t-test, and by race/ethnicity (Hispanic, non-Hispanic black, non-Hispanic white, non-Hispanic other) using analysis of variance. Joinpoint regression estimated yearly increases/decreases in age of diagnosis by sex and race/ethnicity through annual percent changes (APC), which were summarized with average annual percent changes (AAPC). Mean age at diagnosis for oropharyngeal cancer was 60.3 years. While there was initially a decrease in age at diagnosis, a 0.37% annual increase occurred from 2002 to 2016 (APC = 0.37, 95% confidence interval (CI) 0.28, 0.45). For non-oropharyngeal cancer, mean age at diagnosis was 63.2 years, with a continuous increase in age at diagnosis throughout the study period (1975–2016 AAPC = 0.08, 95% CI 0.04, 0.12). Females had higher average age at diagnosis than males for both sites, while blacks (57.4 years for oropharyngeal cancer; 59.0 years for non-oropharyngeal) had the lowest age at diagnosis of all races/ethnicity. Age at diagnosis of oropharyngeal cancer has increased significantly since 2002, while non-oropharyngeal HNC has increased significantly in the last four decades.
