International Expert-Based Consensus Definition, Staging Criteria, and Minimum Data Elements for Osteoradionecrosis of the Jaw: An Inter-Disciplinary Modified Delphi Study

Purpose

Osteoradionecrosis of the jaw (ORNJ) is a severe iatrogenic disease characterized by bone death after radiation therapy (RT) to the head and neck. With over 9 published definitions and at least 16 diagnostic/staging systems, the true incidence and severity of ORNJ are obscured by lack of a standard for disease definition and severity assessment, leading to inaccurate estimation of incidence, reporting ambiguity, and likely under-diagnosis worldwide. This study aimed to achieve consensus on an explicit definition and phenotype of ORNJ and related precursor states through data standardization to facilitate effective diagnosis, monitoring, and multidisciplinary management of ORNJ.

Methods

The ORAL Consortium comprised 69 international experts, including representatives from medical, surgical, radiation oncology, and oral/dental disciplines. Using a web-based modified Delphi technique, panelists classified descriptive cases using existing staging systems, reviewed systems for feature extraction and specification, and iteratively classified cases based on clinical/imaging feature combinations.

Results

The Consortium ORNJ definition was developed in alignment with SNOMED-CT terminology and recent ISOO-MASCC-ASCO guideline recommendations. Case review using existing ORNJ staging systems showed high rates of inability to classify (up to 76%). Ten consensus statements and nine minimum data elements (MDEs) were outlined for prospective collection and classification of precursor/ORNJ stages.

Conclusion

This study provides an international, consensus-based definition and MDE foundation for standardized ORNJ reporting in cancer survivors treated with RT. Head and neck surgeons, radiation, surgical, medical oncologists, and dental specialists should adopt MDEs to enable scalable health information exchange and analytics. Work is underway to develop both a human- and machine-readable knowledge representation for ORNJ (i.e., ontology) and multidisciplinary resources for dissemination to improve ORNJ reporting in academic and community practice settings.

Polygenic prediction of major depressive disorder and related traits in African ancestries UK Biobank participants

Introduction

Genome-Wide Association Studies (GWAS) over-represent European ancestries compared to the global population, neglecting all other ancestry groups and low-income nations. Consequently, polygenic risk scores (PRS) more accurately predict complex traits in Europeans than African Ancestries groups. Very few studies have looked at the transferability of European-derived PRS for behavioural and mental health phenotypes to non-Europeans. We assessed the comparative accuracy of PRS for Major Depressive Disorder (MDD) trained on European and African Ancestries GWAS studies to predict MDD and related traits in African Ancestries participants from the UK Biobank.

Methods

UK Biobank participants were selected based on Principal component analysis (PCA) clustering with an African genetic similarity reference population and MDD was assessed with the Composite International Diagnostic Interview (CIDI). Polygenic Risk Scores (PRS) were computed using PRSice2 using either European or African Ancestries GWAS summary statistics.

Results

PRS trained on European ancestry samples (246,363 cases) predicted case control status in Africans of the UK Biobank with similar accuracies (190 cases, R2=2%) to PRS trained on far much smaller samples of African Ancestries participants from 23andMe, Inc. (5045 cases, R2=1.8%). This suggests that prediction of MDD status from Africans to Africans had greater efficiency per unit increase in the discovery sample size than prediction of MDD from Europeans to Africans. Prediction of MDD status in African UK Biobank participants using GWAS findings of causal risk factors from European ancestries was non-significant.

Conclusion

GWAS studies of MDD in European ancestries are an inefficient means of improving polygenic prediction accuracy in African samples.

Search for a Nonrelativistic Boson in Two-Body Antimuon Decay

We demonstrate the feasibility of probing the charged lepton-flavor-violating decay μ^{+}→e^{+}X^{0} for the presence of a slow-moving neutral boson X^{0} capable of undergoing gravitational binding to large structures and, as such, able to participate in some cosmological scenarios. A short exposure to surface antimuons from beam line M20 at TRIUMF generates a branching ratio limit of ≲10^{-5}. This is comparable to or better than previous searches for this channel, although in a thus-far-unexplored region of X^{0} phase space very close to the kinematic limit of the decay, where m_{X^{0}} approaches m_{μ^{+}}. The future improved sensitivity of the method using a customized p-type point-contact germanium detector is described.

Measurement of Coherent Elastic Neutrino-Nucleus Scattering from Reactor Antineutrinos

The 96.4 day exposure of a 3 kg ultralow noise germanium detector to the high flux of antineutrinos from a power nuclear reactor is described. A very strong preference (p<1.2×10^{-3}) for the presence of a coherent elastic neutrino-nucleus scattering (CEνNS) component in the data is found, when compared to a background-only model. No such effect is visible in 25 days of operation during reactor outages. The best-fit CEνNS signal is in good agreement with expectations based on a recent characterization of germanium response to sub-keV nuclear recoils. Deviations of order 60% from the standard model CEνNS prediction can be excluded using present data. Standing uncertainties in models of germanium quenching factor, neutrino energy spectrum, and background are examined.

Long-term outcomes of a phase II trial of neoadjuvant immunotherapy for advanced, resectable cutaneous squamous cell carcinoma of the head and neck (CSCC-HN)

9519

Background: In a pilot phase II trial, we investigated the use of neoadjuvant immunotherapy to induce a pathologic response in patients with stage III/IV (M0) cutaneous squamous cell carcinoma of the head and neck (CSCC-HN). Here, we report the long-term outcomes according to pathologic response. Methods: Patients with newly diagnosed or recurrent stage III/IV (M0) (AJCC 8th Ed) CSCC-HN were treated with 2 doses of cemiplimab 350 mg intravenously every 3 weeks prior to surgery. The primary endpoint was overall response rate (ORR) per RECIST v1.1. Secondary endpoints included safety, pathologic response, disease-free and overall survival. Results: Of 20 patients enrolled, 7 (35%) had recurrent disease and 12 (60%) were stage IV on presentation. Neoadjuvant immunotherapy was generally well-tolerated and there were no surgical delays. Adverse events (AEs) were observed in 7 (35%) patients; 1 (5%) grade 3 diarrhea, 6 (30%) ≤ grade 2 AEs. ORR by RECIST was 30%. However, 85% (17/20) achieved a pathologic response (≤50% viable tumor), with pathologic complete response (pCR) in 11 (55%), major pathologic response (MPR, ≤10% viable tumor) in 4 (20%) and pathologic partial response (pPR, >10% and ≤50% viable tumor) in 2 (10%). Patients with a pCR did not receive planned radiotherapy after surgery. Patients who did not have a pathologic response (> 50% viable tumor) either progressed and died (1, 5%) or developed recurrence (2, 10%) despite surgery and adjuvant radiation or chemoradiation. At a median follow up of 34.5 months (range: 7.7-42.7), none of the patients who achieved a pathologic response have recurred. Conclusions: Consistent with other cancer types, pathologic response to neoadjuvant immunotherapy is durable in patients with advanced, resectable CSCC-HN. Adjuvant radiation therapy may be spared in patients who achieve a pCR and warrants further investigation. Clinical trial information: NCT03565783.

Outcomes after definitive surgery for mandibular osteoradionecrosis

OBJECTIVES

To analyze charges, complications, survival, and functional outcomes for definitive surgery of mandibular osteoradionecrosis (ORN).

MATERIALS AND METHODS

Retrospective analysis of 76 patients who underwent segmental mandibulectomy with reconstruction from 2000 to 2009.

RESULTS

Complications occurred in 49 (65%) patients and were associated with preoperative drainage (odds ratio [OR] 4.40, 95% confidence interval [CI] 1.01-19.27). The adjusted median charge was $343 000, and higher charges were associated with double flap reconstruction (OR 8.15, 95% CI 2.19-30.29) and smoking (OR 5.91, 95% CI 1.69-20.72). Improved swallow was associated with age <67 years (OR 3.76, 95% CI 1.16-12.17) and preoperative swallow (OR 3.42, 95% CI 1.23-9.51). Five-year ORN-recurrence-free survival was 93% while overall survival was 63% and associated with pulmonary disease (HR [hazard ratio] 3.57, 95% CI 1.43-8.94).

CONCLUSIONS

Although recurrence of ORN is rare, surgical complications are common and charges are high. Poorer outcomes and higher charges are associated with preoperative factors.

Enhanced recovery after surgery (ERAS) in head and neck oncologic surgery: Impact on return to intended oncologic therapy (RIOT) and survival

BACKGROUND

Enhanced Recovery After Surgery (ERAS) pathways in head and neck cancer (HNC) have shown to improve perioperative outcomes and reduce complications. The longer term implications on adjuvant treatment and survival have not been studied. We hereby report the first study on the impact of an ERAS pathway on return to intended oncologic treatment (RIOT) and overall survival (OS) in HNC.

METHODS

200 patients undergoing head and neck oncologic surgery on an ERAS pathway between March 1, 2016 and March 31, 2019 were matched to controls over the same interval. Demographic, tumor and adjuvant therapy-related data were collected, including time to adjuvant therapy(TAT) and treatment package time(TPT). Risk factors for TAT > 42 days and TPT ≥ 85 days were assessed. OS was compared and risk factors for inferior OS determined.

RESULTS

Baseline characteristics including co-morbidities and tumor stage were similar. Of 179 patients planned for adjuvant treatment, there was no difference in RIOT rate (89.0% vs 87.5%, p = 0.753), proportion of TAT > 42 days of surgery (55.6% vs 59.7%, p = 0.642), or TPT ≥ 85 days (48.1% vs 57.1, p = 0.258), for the ERAS and control groups, respectively. On multivariate analysis, alcohol use (OR 3.58; 95 %CI 1.11-11.52) and recurrent disease status (OR 2.88; 95 %CI 1.40-5.93) were independently associated with prolonged TAT. Three-year OS was similar between the ERAS and control groups (73% vs 76%, p = 0.521).

CONCLUSION

ERAS has not shown to improve RIOT or OS in the current study. However, its benefit for perioperative outcomes is undeniable and further studies are required on longer term quality and survival outcomes.

Impact of Body Mass Index on Surgical Outcomes in Oncologic Microvascular Head and Neck Reconstruction

BACKGROUND

Despite increasing recognition, obesity continues to represent a major health issue for millions of people in the USA and worldwide. There is a paucity in the literature regarding the effect of body mass index (BMI) on microsurgical head and neck reconstruction. The present study hypothesized that high BMI is predictive of postoperative recipient- and donor-site complications with longer operative times.

PATIENTS AND METHODS

Retrospective review of patients who underwent free flap surgery for head and neck reconstruction was performed between January 2005 and December 2018. Patients were categorized into four groups based on BMI: < 20 kg/m², 20-30 kg/m², 30-40 kg/m², and ≥ 40 kg/m². Patient characteristics and surgical outcomes were compared between the four groups.

RESULTS

Overall, 4000 free flap surgeries were included in the present study, performed on 3753 patients, of whom 9.9% had a BMI < 20 kg/m², 64.9% had a BMI between 20 and 30 kg/m², 21.6% had a BMI between 30 and 40 kg/m², and 3.6% had a BMI ≥ 40 kg/m². After adjusting for potential confounders, multivariate analysis showed no association between BMI and any complication, major recipient complications, or total flap loss. However, multivariate linear regression model showed BMI 30-40 kg/m² and BMI ≥ 40 kg/m² to be independently associated with longer operative times compared with BMI < 20 kg/m².

CONCLUSION

Obesity and high BMI increase operative times; however, with meticulous surgical technique and diligent postoperative care, microvascular head and neck reconstructions can be performed safely and reliably in the majority of patients regardless of BMI with similar overall, recipient-site, and donor-site complications.

COVID-19 infection and its consequences among surgical oncology patients: A systematic analysis, meta-analysis and meta-regression

We conducted this meta‐analysis to address the outcomes in cancer patients after oncologic surgery during COVID‐19 pandemic. The primary endpoint was the COVID‐19–related mortality rate. Higher body mass index was significantly and negatively associated with higher all‐cause mortality and in‐hospital COVID‐19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all‐cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID‐19 infection rate.

Multifocal regression and pathologic response predicts recurrence after neoadjuvant chemotherapy in head and neck squamous cell carcinoma

OBJECTIVES

Complete pathological response after neoadjuvant chemotherapy (NAC) in head and neck squamous cell carcinomas (HNSCC) is a good prognostic factor. Multifocal regression post-NAC in breast cancer has proven to impact locoregional control (LRC) but has not been evaluated in HNSCC. We evaluate the impact of multifocal regression and major pathologic response (MPR) on survival indices in HNSCC.

MATERIALS AND METHODS

Retrospective review of HNSCC patients receiving NAC followed by surgery with curative intent between March 2016 to March 2019 at MD Anderson Cancer Center. Tumor focality (uni- or multifocal), pathologic response and other pathologic data were collected. MPR was defined as ≤ 10% residual tumor. Overall survival (OS) and LRC were analyzed and multivariate Cox regression analysis was performed.

RESULTS

101 patients were analyzed, with 18.8% pathologic complete response, 18.8% with 1-10% viable tumor and 60.4% with > 10% viable tumor. 61 (60.4%) had unifocal disease while 19 (18.8%) had multifocal disease. Tumor focality was significantly associated with LRC but not OS, where the 3-year LRC was 82%, 69% and 52% (p = 0.015) for no viable tumor, unifocal disease and multifocal disease respectively. On multivariate analysis, multifocal disease (HR 10.43; 95 %CI 1.24-87.5) and extranodal extension (HR 4.4; 95 %CI 1.60-12.07) continued to be significant independent predictors of LRC. MPR group displayed significantly better 3-year OS (75% vs 51%, p = 0.041) and 3-year LRC (80% vs 62%, p = 0.011) than those with > 10% viable tumor.

CONCLUSION

Multifocal regression and less than MPR after NAC in HNSCC predicts for locoregional recurrence and should be routinely reported.

Pilot Phase II Trial of Neoadjuvant Immunotherapy in Locoregionally Advanced, Resectable Cutaneous Squamous Cell Carcinoma of the Head and Neck

PURPOSE

In locoregionally advanced, resectable cutaneous squamous cell carcinoma of the head and neck (CSCC-HN), surgery followed by radiotherapy is standard but can be cosmetically and functionally devastating, and many patients will have recurrence.

PATIENTS AND METHODS

Newly diagnosed or recurrent stage III-IVA CSCC-HN patients amenable to curative-intent surgery received two cycles of neoadjuvant PD-1 inhibition. The primary endpoint was ORR per RECIST 1.1. Secondary endpoints included pathologic response [pathologic complete response (pCR) or major pathologic response (MPR; ≤10% viable tumor)], safety, DSS, DFS, and OS. Exploratory endpoints included immune biomarkers of response.

RESULTS

Of 20 patients enrolled, 7 had recurrent disease. While only 6 patients [30%; 95% confidence interval (CI), 11.9-54.3] had partial responses by RECIST, 14 patients (70%; 95% CI, 45.7-88.1) had a pCR (n = 11) or MPR (n = 3). No SAEs ocurred during or after the neoadjuvant treatment. At a median follow-up of 22.6 months (95% CI, 21.7-26.1), one patient progressed and died, one died without disease, and two developed recurrence. The 12-month DSS, DFS, and OS rates were 95% (95% CI, 85.9-100), 89.5% (95% CI, 76.7-100), and 95% (95% CI, 85.9-100), respectively. Gene expression studies revealed an inflamed tumor microenvironment in patients with pCR or MPR, and CyTOF analyses demonstrated a memory CD8+ T-cell cluster enriched in patients with pCR.

CONCLUSIONS

Neoadjuvant immunotherapy in locoregionally advanced, resectable CSCC-HN is safe and induces a high pathologic response rate. Pathologic responses were associated with an inflamed tumor microenvironment.

Consensus of free flap complications: Using a nomenclature paradigm in microvascular head and neck reconstruction

BACKGROUND

We aim to define a set of terms for common free flap complications with evidence-based descriptions.

METHODS

Clinical consensus surveys were conducted among a panel of head and neck/reconstructive surgeons (N = 11). A content validity index for relevancy and clarity for each item was computed and adjusted for chance agreement (modified kappa, K). Items with K < 0.74 for relevancy (i.e., ratings of "good" or "fair") were eliminated.

RESULTS

Five out of nineteen terms scored K < 0.74. Eliminated terms included "vascular compromise"; "cellulitis"; "surgical site abscess"; "malocclusion"; and "non- or mal-union." Terms that achieved consensus were "total/partial free flap failure"; "free flap takeback"; "arterial thrombosis"; "venous thrombosis"; "revision of microvascular anastomosis"; "fistula"; "wound dehiscence"; "hematoma"; "seroma"; "partial skin graft failure"; "total skin graft failure"; "exposed hardware or bone"; and "hardware failure."

CONCLUSION

Standardized reporting would encourage multi-institutional research collaboration, larger scale quality improvement initiatives, the ability to set risk-adjusted benchmarks, and enhance education and communication.

Association Between Multimodal Analgesia Administration and Perioperative Opioid Requirements in Patients Undergoing Head and Neck Surgery With Free Flap Reconstruction

Importance

The opioid epidemic has reignited interest in opioid-sparing strategies in managing pain. However, few studies have focused on opioid use during perioperative care in patients undergoing head and neck surgery with free flap reconstruction.

Objectives

To examine the association between multimodal analgesia (MMA) administration and perioperative opioid requirements in patients undergoing head and neck surgery with free flap reconstruction and to investigate whether MMA alters the duration of stay in the postanesthesia care unit (PACU).

Design, Setting, and Participants

In this retrospective case-control study, data were collected between April 1, 2016, and December 31, 2017. The study was conducted at a single cancer center in the United States. Participants were 357 patients 18 years or older scheduled for head and neck surgery with free flap reconstruction.

Exposures

Patients in the treatment group received oral celecoxib, gabapentin, and/or tramadol hydrochloride before surgery. Control group patients did not receive any of these medications.

Main Outcomes and Measures

The amount of opioid administered in the operating room and in the PACU was converted to morphine equivalent daily dose (MEDD) for comparison between the 2 groups. The duration of stay in the PACU was based on the start time and end time of PACU care recorded by nurses in the PACU.

Results

In total, 149 patients (mean [SD] age, 60.3 [13.7] years; 104 [69.8%] men) were included in the treatment group, and 208 patients (mean [SD] age, 64.2 [13.6] years; 146 [70.2%] men) were included in the control group. The mean (SD) MEDD of opioid given during surgery was 51.7 (19.8) in the treatment group and 67.9 (24.7) in the control group, for a difference in the means (treatment vs control) of -16.17 (95% CI, -20.81 to -11.52). In the PACU, the mean (SD) MEDD of opioid given was 11.7 (13.3) in the treatment group and 14.9 (15.7) in the control group, for a difference in the means (treatment vs control) of -3.22 (95% CI, -6.40 to -0.03). The MMA treatment remained largely associated with reduced amount of opioid given during surgery, in the PACU, and both combined after controlling for other important factors.

Conclusions and Relevance

This case-control study found that the patients who received MMA before head and neck surgery with free flap reconstruction required less opioid medication. The treatment group also had shorter duration of stay in the PACU compared with the control group.

Comparison of Internal Patient Satisfaction Scores at a Cancer Center With Star Ratings on Online Physician-Rating Websites

PURPOSE

Patients have been increasingly using physician-rating websites (PRWs); however, few studies have analyzed the validity of star ratings on PRWs. We aimed to compare PRW patient satisfaction scores with internally generated patient satisfaction scores (internal scores) of physicians at a large quaternary cancer center.

METHODS

We collected internal scores and PRW scores for physicians at MD Anderson Cancer Center. Internal scores were based on patient responses to the Clinician and Group Consumer Assessment of Healthcare Providers and Systems patient experience (CG-CAHPS) survey. Only physicians with an internal score on the basis of ≥ 30 patient reviews were included. The median numbers of reviews and median scores were compared between internal data and four PRWs (Google, HealthGrades, Vitals, and WebMD). Both internally and on PRWs, possible scores ranged from 1 (least satisfied) to 5 (most satisfied).

RESULTS

Of 640 physicians with an internal score, 510 (79.7%) met the inclusion criteria. For these 510 physicians, the median (IQR) number of internal reviews was 49.5 (30-93) and the median (IQR) internal score was 4.89 (4.81-4.93); the median number of reviews on PRWs ranged from 2 to 7, and the median score on PRWs ranged from 4.40 to 5.00. No physician had an internal score < 4, but the proportions with score < 4 on PRWs ranged from 16% to 30%.

CONCLUSION

Internal patient satisfaction scores were higher and calculated from more reviews than PRW patient satisfaction scores and correlated weakly with PRW scores. Given that patients rely on PRWs when evaluating potential physicians, we recommend publishing internal scores online to give patients more complete information regarding physician performance.

Delay to surgery after neoadjuvant chemotherapy in head and neck squamous cell carcinoma affects oncologic outcomes

BACKGROUND

Neoadjuvant chemotherapy (NAC) is used in head and neck squamous cell carcinoma (HNSCC) for downstaging advanced disease and decreasing distant metastasis (DM). To the authors' knowledge, no study has specifically examined the impact of a delayed time to surgery (TTS) after NAC on oncologic outcomes. They thus aimed to identify a cutoff for TTS after NAC and its effect on survival indices.

METHODS

This was a retrospective review of all patients with HNSCC receiving NAC followed by surgery with curative intent between March 2016 and March 2019 at the MD Anderson Cancer Center. Receiver operating characteristic analysis was used to identify a cutoff for TTS, and this cutoff was used to analyze the overall survival (OS), locoregional recurrence rate, DM-free rate, and disease-free survival (DFS). A multivariate Cox regression analysis was performed.

RESULTS

One hundred one patients were analyzed with a median follow-up of 24.7 months. The 3-year OS and locoregional recurrence rates did not differ with a TTS ≥ 34 days. However, the 3-year DM-free rate was significantly worse (56% vs 90%; P = .001) in the group with a TTS ≥ 34 days, and the 3-year DFS was significantly lower (26% vs 64%; P = .006). In a multivariate analysis, a TTS ≥ 34 days (hazard ratio [HR], 4.92; 95% confidence interval [CI], 1.84-13.13) and extracapsular extension (HR, 3.01; 95% CI, 1.13-8.00) were significant independent predictors of a poorer DM-free rate. Weight loss > 10% (HR, 5.53; 95% CI, 1.02-30.24) was the only independent predictor for a TTS ≥ 34 days.

CONCLUSIONS

Emphasis should be placed on early definitive locoregional treatment after NAC, particularly in patients who do not respond to NAC. There is a need to validate these findings and establish new benchmarks for the interval between NAC and surgery.

Impact of provider type and number of providers on surveillance testing among survivors of head and neck cancers

BACKGROUND

Guidelines for follow-up after head and neck cancer (HNC) treatment recommend frequent clinical examinations and surveillance testing. Here, the authors describe real-world follow-up care for HNC survivors and variations in surveillance testing.

METHODS

Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, this study examined a population-based cohort of HNC survivors between 2001 and 2011 Usage of cross-sectional head and neck imaging (CHNI), chest imaging (CI), positron emission tomography (PET), fiberoptic nasopharyngolaryngoscopy (FNPL), and, in irradiated patients, thyroid function testing (TFT) was captured over 2 consecutive surveillance years. Multivariate modeling with logistic regression analyses was used to assess variations by clinical factors, nonclinical factors, number and types of providers seen and their evolution over time.

RESULTS

Among 13,836 HNC survivors, the majority saw a medical, radiation, or surgical oncologist and a primary care provider (PCP; 81.7%) in their first year of surveillance. However, only 58.1% underwent either PET or CHNI, 47.8% underwent CHNI, 64.1% underwent CI, 32.5% underwent PET scans, 55.0% underwent FNPL, and 55.9% underwent TFT. In multivariate analyses, patients who followed up with more providers and those who followed up with both a PCP and an oncologist were more likely to undergo surveillance testing (P < .007). However, adjusting for providers seen did not explain the variations in surveillance testing rates based on age, race, education, income level, and place of residence. Over time, there was a gradual increase in the use of PET scans and TFT during surveillance years.

CONCLUSIONS

In this large SEER-Medicare data study, only half of HNC survivors received the recommended testing, and greater compliance was seen in those who followed up with both an oncologist and a PCP. More attention is needed to minimize variations in surveillance testing across sociodemographic groups.

Risk-adjustment models in patients undergoing head and neck surgery with reconstruction

BACKGROUND

With the current focus on value-based outcomes and reimbursement models, perioperative risk adjustment is essential. Specialty surgical outcomes are not well predicted by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP); the Head and Neck-Reconstructive Surgery NSQIP was created as a specialty-specific platform for patients undergoing head and neck surgery with flap reconstruction. This study aims to investigate risk prediction models in these patients.

METHODS

The Head and Neck-Reconstructive Surgery NSQIP collected data on patients undergoing head and neck surgery with flap reconstruction from August 1, 2012 to October 20, 2016. Multivariable logistic regression models were created for 9 outcomes (postoperative ventilator dependence, pneumonia, superficial recipient surgical site infection, presence of tracheostomy/nasoenteric (NE)/gastrostomy/gastrojejunostomy(G/GJ) tube 30 days postoperatively, conversion from NE to G/GJ tube, unplanned return to the operating room, length of stay > 7 days). External validation was completed with a more contemporary cohort.

RESULTS

A total of 1095 patients were included in the modelling cohort and 407 in the validation cohort. Models performed well predicting tracheostomy, NE, G/GJ tube presence at 30 days postoperatively and conversion from NE to G/GJ tube (c-indices = 0.75-0.91). Models for postoperative pneumonia, superficial recipient surgical site infection, ventilator dependence > 48 h, and length of stay > 7 days were fair (concordance [c]-indices = 0.63-0.69). The predictive model for unplanned return to the operating room was poor (c-index = 0.58).

CONCLUSIONS AND RELEVANCE

Reliable and discriminant risk prediction models were able to be created for postoperative outcomes using the specialty-specific Head and Neck-Reconstructive Surgery Specific NSQIP.

Enhanced Recovery After Surgery (ERAS) in Head and Neck Oncologic Surgery: A Case-Matched Analysis of Perioperative and Pain Outcomes

BACKGROUND

Enhanced recovery after surgery (ERAS) pathways are well established in certain surgical specialties because findings have shown significant improvements in outcomes. Convincing literature in head and neck cancer (HNC) surgery is lacking. This study aimed to assess the effect of an ERAS pathway on National Surgical Quality Improvement Program (NSQIP)-based occurrences and pain-related outcomes in HNC surgery.

METHODS

The study matched 200 patients undergoing head and neck oncologic surgery on an ERAS pathway between 1 March 2016 and 31 March 2019 with control subjects (1:1 ratio) during the same period. Demographic and perioperative data collected from the NSQIP database were extracted. Pain scores and medication usage were electronically extracted from our electronic medical record system and compared. Risk factors for high opioid usage also were assessed.

RESULTS

Both groups were statistically similar in baseline characteristics. The ERAS group had fewer planned intensive care unit (ICU) admissions (4% vs. 14%; p < 0.001), a shorter mean hospital stay (7.2 ± 2.3 vs. 8.7 ± 4.2 days; p < 0.001), and fewer overall complications (18.6% vs. 27.0%; p = 0.045). Morphine milligram equivalent requirements over 72 h were significantly reduced during 72 h in the ERAS group (138.8 ± 181.5 vs. 207.9 ± 205.5; p < 0.001). In the multivariate analysis, the risk factors for high opioid analgesic usage included preoperative opioid usage, age younger than 65 years, race, patient-controlled analgesia use, and ICU admission.

CONCLUSION

The study findings showed that ERAS in HNC surgery can result in improved outcomes and resource use, and that these results are sustainable. The outcomes described in this report can be further used to optimize ERAS pathways.

Association between postoperative complications and long-term oncologic outcomes following total laryngectomy: 10-year experience at MD Anderson Cancer Center

BACKGROUND

Postoperative complications are an independent predictor of poor survival across several tumors. However, there is limited literature on the association between postoperative morbidity and long-term survival following total laryngectomy (TL) for cancer.

METHODS

We conducted a retrospective review of all TL patients at a single institution from 2008 to 2013. Demographic and clinical data were collected and analyzed, including postsurgical outcomes, which were classified using the Clavien-Dindo system. Multivariable Cox regression analyses were performed to identify factors associated with overall survival (OS) and disease-free survival (DFS).

RESULTS

A total of 362 patients were identified. The mean age was 64 years, and the majority of patients were male (81%). The median follow-up interval was 21 months. Fifty-seven percent of patients had received preoperative radiation, and 40% had received preoperative chemotherapy. Fifty-seven percent of patients underwent salvage TL, and 60% underwent advanced reconstruction (45% free flap and 15% pedicled flap). A total of 136 patients (37.6%) developed postoperative complications, 92 (25.4%) of which were major. Multivariable modeling demonstrated that postoperative complications independently predicted shorter OS (hazard ratio [HR], 1.50; 95% CI, 1.16-1.96; P = .002) and DFS (HR, 1.36; 95% CI, 1.05-1.76; P = .021). Other independent negative predictors of OS and DFS included positive lymph node status, preoperative chemotherapy, comorbidity grade, and delayed adjuvant therapy. Severity of complication and reason for TL (salvage vs primary) were not shown to be predictive of OS or DFS.

CONCLUSION

Postoperative complications are associated with worse long-term OS and DFS relative to uncomplicated cases. Patient optimization and timely management of postoperative complications may play a critical role in long-term survival.

Development and validation of a Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN-HN) in a scarce resource setting: Response to the COVID-19 pandemic

Background

In the wake of the coronavirus disease 2019 (COVID‐19) pandemic, access to surgical care for patients with head and neck cancer (HNC) is limited and unpredictable. Determining which patients should be prioritized is inherently subjective and difficult to assess. The authors have proposed an algorithm to fairly and consistently triage patients and mitigate the risk of adverse outcomes.

Methods

Two separate expert panels, a consensus panel (11 participants) and a validation panel (15 participants), were constructed among international HNC surgeons. Using a modified Delphi process and RAND Corporation/University of California at Los Angeles methodology with 4 consensus rounds and 2 meetings, groupings of high‐priority, intermediate‐priority, and low‐priority indications for surgery were established and subdivided. A point‐based scoring algorithm was developed, the Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN‐HN). Agreement was measured during consensus and for algorithm scoring using the Krippendorff alpha. Rankings from the algorithm were compared with expert rankings of 12 case vignettes using the Spearman rank correlation coefficient.

Results

A total of 62 indications for surgical priority were rated. Weights for each indication ranged from −4 to +4 (scale range; −17 to 20). The response rate for the validation exercise was 100%. The SPARTAN‐HN demonstrated excellent agreement and correlation with expert rankings (Krippendorff alpha, .91 [95% CI, 0.88‐0.93]; and rho, 0.81 [95% CI, 0.45‐0.95]).

Conclusions

The SPARTAN‐HN surgical prioritization algorithm consistently stratifies patients requiring HNC surgical care in the COVID‐19 era. Formal evaluation and implementation are required.

Lay Summary

Many countries have enacted strict rules regarding the use of hospital resources during the coronavirus disease 2019 (COVID‐19) pandemic. Facing delays in surgery, patients may experience worse functional outcomes, stage migration, and eventual inoperability.

Treatment prioritization tools have shown benefit in helping to triage patients equitably with minimal provider cognitive burden.

The current study sought to develop what to the authors' knowledge is the first cancer–specific surgical prioritization tool for use in the COVID‐19 era, the Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN‐HN). This algorithm consistently stratifies patients requiring head and neck cancer surgery in the COVID‐19 era and provides evidence for the initial uptake of the SPARTAN‐HN.

To the authors' knowledge, the Surgical Prioritization and Ranking Tool and Navigation Aid for Head and Neck Cancer (SPARTAN‐HN) is the first cancer surgery–specific prioritization tool for use during the coronavirus disease 2019 (COVID‐19) pandemic. The SPARTAN‐HN algorithm is reliable and valid for the stratification of patients with head and neck cancer who require urgent cancer care in resource‐restricted practice environments.

COVID-19 pandemic and health care disparities in head and neck cancer: Scanning the horizon

The COVID-19 pandemic has profoundly disrupted head and neck cancer (HNC) care delivery in ways that will likely persist long term. As we scan the horizon, this crisis has the potential to amplify preexisting racial/ethnic disparities for patients with HNC. Potential drivers of disparate HNC survival resulting from the pandemic include (a) differential access to telemedicine, timely diagnosis, and treatment; (b) implicit bias in initiatives to triage, prioritize, and schedule HNC-directed therapy; and (c) the marked changes in employment, health insurance, and dependent care. We present four strategies to mitigate these disparities: (a) collect detailed data on access to care by race/ethnicity, income, education, and community; (b) raise awareness of HNC disparities; (c) engage stakeholders in developing culturally appropriate solutions; and (d) ensure that surgical prioritization protocols minimize risk of racial/ethnic bias. Collectively, these measures address social determinants of health and the moral imperative to provide equitable, high-quality HNC care.

Head and neck surgical oncology in the time of a pandemic: Subsite-specific triage guidelines during the COVID-19 pandemic

BACKGROUND

COVID-19 pandemic has strained human and material resources around the world. Practices in surgical oncology had to change in response to these resource limitations, triaging based on acuity, expected oncologic outcomes, availability of supportive resources, and safety of health care personnel.

METHODS

The MD Anderson Head and Neck Surgery Treatment Guidelines Consortium devised the following to provide guidance on triaging head and neck cancer (HNC) surgeries based on multidisciplinary consensus. HNC subsites considered included aerodigestive tract mucosa, sinonasal, salivary, endocrine, cutaneous, and ocular.

RECOMMENDATIONS

Each subsite is presented separately with disease-specific recommendations. Options for alternative treatment modalities are provided if surgical treatment needs to be deferred.

CONCLUSION

These guidelines are intended to help clinicians caring for patients with HNC appropriately allocate resources during a health care crisis, such as the COVID-19 pandemic. We continue to advocate for individual consideration of cases in a multidisciplinary fashion based on individual patient circumstances and resource availability.

Evaluating Unplanned Returns to the Operating Room in Head and Neck Free Flap Patients

BACKGROUND

Head and neck oncologic surgery with reconstruction represents one of the most complex operations in otolaryngology. Unplanned return to the operating room represents an objective measure of postoperative complications. The purpose of this study was to identify reasons and risk factors for unplanned return to the operating room in patients undergoing head and neck surgery with reconstruction.

METHODS

This retrospective cohort study of 467 patients undergoing head and neck surgery with free flap reconstruction used a previously-developed Head and Neck-Reconstructive Surgery-specific National Surgical Quality Improvement Program. Disease and site-specific preoperative, intraoperative, and postoperative data were gathered. Comparisons between those with and without an unexpected return to the operating room were completed with univariate and multiple logistic regression models.

RESULTS

The rate of unexpected return to the operating room was 18.8% (88 patients). Most common reasons for URTOR were flap compromise (24 patients, 5.1%), postoperative infection (21 patients, 4.5%), and hematoma (20 patients, 4.3%). Two risk factors were identified by multivariate analysis: coagulopathy (OR_adjusted = 2.83, 95% CI = 1.24-6.19, P = 0.010), and use of alcohol (OR_adjusted = 1.9, 95% CI = 1.14-3.33, P = 0.025).

CONCLUSIONS

Preexisting coagulopathy and increased alcohol consumption were associated with increased risk of unexpected return to the operating room. These findings can aid physicians in preoperative patient counseling and medical optimization and can inform more precise risk stratification of patients undergoing head and neck surgery with reconstruction. Strategies to prevent and mitigate unexpected returns to the operating room will improve patient outcomes, decrease resource utilization, and facilitate successful integration into alternative payment models.

Utilization of rehabilitation services in patients with head and neck cancer in the United States: A SEER-Medicare analysis

BACKGROUND

Head and neck cancer (HNC) and its treatment lead to functional impairments. Rehabilitation by speech-language pathology (SLP) and occupational/physical therapy (OT/PT) can decrease morbidity.

METHODS

The Surveillance, Epidemiology and End Results-Medicare data for patients with HNC diagnosed between 2002 and 2011 was utilized to evaluate posttreatment rehabilitation.

RESULTS

In 16 194 patients, the overall utilization rate was 20.7% for SLP and 26.2% for OT/PT services. Treatment modality was significantly associated rehabilitation utilization. Compared to patients treated with primary surgery, those treated with primary radiotherapy had significantly lower odds of OT/PT utilization. Patients treated with surgery plus adjuvant treatment and primary concurrent chemoradiation had higher odds of SLP utilization compared to patients treated with surgery alone.

CONCLUSIONS

Rehabilitation services appeared to be underutilized by patients with HNC in the United States and vary with treatment modality. There is a need to improve integration of rehabilitation services into the HNC care continuum.

SUMMARY

Rehabilitation services are underutilized by patients with HNC during posttreatment surveillance in the United States. Treatment modality significantly impacts rehabilitation utilization patterns.

A data review of airway management in patients with oral cavity or oropharyngeal cancer: a single-institution experience

Background

Oral cavity and oropharyngeal cancer impose significant threat to airway management. Head and neck radiotherapy (HNRT) may further increase the difficulty of tracheal intubation. We hypothesized that a history of HNRT would be associated with a high rate of difficult tracheal intubation.

Methods

Adult patients with a history of HNRT were identified. Non-HNRT controls were case-matched by age, sex and body mass index. The tracheal intubation status between the two patient groups (treated vs. untreated with HNRT) was compared. The t test was used to evaluate differences in continuous variables between the 2 groups. Fisher’s exact test or a chi-square test was used to test for associations between radiation status and patient characteristics that may be associated with difficult tracheal intubation. Odds ratio and its confidence interval were used to assess the effect of radiation status on intubation status.

Results

The final cohort of 472 matched patients in age, sex and body mass index consisted of 236 patients who had HNRT before surgery and 236 who had upfront surgery without HNRT. The percentage of patients who had restricted neck range of motion in the HNRT group was significantly higher than in the control group (22.3% vs. 11.0%; p = 0.001). The proportion of patients with trismus (p = 0.11) or difficult tracheal intubation (p = 0.73) did not differ significantly between the 2 groups. 12.7% patients in the study had difficult tracheal intubation. Patients who had mallampati scores of 3 or 4 had significantly higher rate of difficult tracheal intubation than did patients with mallampati scores of 1 or 2 (17.8% vs. 8.7%; p = 0.004). Multivariate logistic regression model showed no difference between HNRT and intubation status after adjusting neck range of motion and mallampati score (OR = 0.91, 95% CI: 0.510 to1.612).

Conclusions

Previous treatment with HNRT was not associated with additional risk of difficult tracheal intubation. Mallampati score may be a sensitive measurement for difficult tracheal intubation in this patient population.

Two-year prevalence of dysphagia and related outcomes in head and neck cancer survivors: An updated SEER-Medicare analysis

BACKGROUND

The aim of the study was to examine prevalence of dysphagia at the population level in head and neck cancer (HNC) survivors.

METHODS

Surveillance, Epidemiology, and End Results-Medicare claims among 16 194 patients with HNC (2002-2011) were analyzed to estimate 2-year prevalence of dysphagia, stricture, and aspiration pneumonia, and derive treatment- and site-specific estimates.

RESULTS

Prevalence of dysphagia, stricture, pneumonia, and aspiration pneumonia was 45.3% (95% confidence interval [CI]: 44.5-46.1), 10.2% (95% CI: 9.7-10.7), 26.3% (95% CI: 25.6-26.9), and 8.6% (95% CI: 8.2-9.1), respectively. Dysphagia increased by 11.7% over the 10-year period (P < .001). Prevalence was highest after chemoradiation and multimodality therapy.

CONCLUSION

Comparing to published rates using similar methodology the preceding decade (1992-1999), prevalence of dysphagia based on claims data was similar in 2002-2011 in this study. These results suggest persistence of dysphagia as a highly prevalent morbidity, even in the decade in which highly conformal radiotherapy and minimally invasive surgeries were popularized.

Risk-adjusted prediction models using the specialty-specific head and neck reconstructive surgery NSQIP

240

Background: With increasing health care costs, risk-adjusted quality outcomes are essential. The American College of Surgeons – National Surgical Quality Improvement Program (ACS-NSQIP) is a robust perioperative risk-adjustment platform, but lacks capture of oncologic- and specialty-specific variables and has limited utility for risk adjustment in head and neck oncologic surgery. This study uses the specialty-specific Head and Neck-Reconstructive Surgery (HNSR) NSQIP to develop risk-adjusted models for patients undergoing head and neck oncologic surgery with reconstruction. Methods: Multiple logistic regression modelling using data from patients in the HNSR NSQIP between 8/2012-10/2016 identified predictors of postoperative morbidity. Final models were validated using a cohort of patients treated between 10/2016-12/2017. The concordance index (c-index) was used to evaluate the model performance. Results: The modelling cohort included 1095 patients and the validation cohort included 407. Models were created to predict probability of postoperative complications (presence of fistula, ventilator dependence > 48 hours, pneumonia, deep/superficial surgical site infection); presence of gastrostomy-jejunostomy (GJ), nasoenteric (NE), or tracheostomy tube at 30 days postoperatively; conversion from NE to GJ tube; unplanned return to the operating room; and length of stay > 7 days. Most discriminant models were those predicting presence of GJ tube (model c-index [MCI] = 0.91; validation c-index[VCI] = 0.93), NE tube (MCI= 0.83; VCI= 0.84), and conversion from NE to GJ tube (MCI= 0.86; VCI= 0.80). Prediction models were least discriminant for ventilator dependence (MCI= 0.63; VCI= 0.45), fistula (MCI= 0.58; VCI= 0.54), and unplanned return to the operating room (MCI= 0.59; VCI= 0.51). Conclusions: Reliable and discriminant risk prediction models were able to be created for a variety of perioperative complications incorporating oncologic- and specialty-specific variables in the HNSR NSQIP. These models help inform risk stratification strategies for patients undergoing head and neck reconstructive surgery and the development of a specialty-specific preoperative risk calculators.

The effect of facility volume on treatment guideline compliance and overall survival in oral tongue squamous cell carcinoma

17

Background: National treatment guidelines guide cancer care using the best available evidence and understanding the drivers of guideline compliance is essential to identifying modifiable factors to improve quality of care. This study aims to explore the impact of facility volume on the rate of guideline compliance in patients with oral tongue cancer and its effect on overall survival. Methods: Using National Cancer Database from 2004 to 2013, this retrospective cohort study investigated patients undergoing curative surgical treatment for oral tongue squamous cell carcinoma. Patients were divided into three tertiles according to mean annual case volume at their treatment facility. Guideline compliance was based on the National Comprehensive Cancer Network oral cavity cancer guidelines. Predictors of guideline compliance and overall survival were determined using multiple logistic regression and Cox Proportional Hazards models. Results: Guideline compliant care was delivered in 54.5% of the 35,810 eligible patients. Those treated at intermediate volume facilities had 1.75 times greater odds of receipt of guideline compliant care (95% CI = 1.57-1.96) and 2.14 times greater in high volume facilities (95% CI = 1.91-2.40) compared to low volume facilities. Guideline compliance (adjusted hazard ratio [HRadj] = 0.78, 95% CI = 0.72-0.84) and treatment at a high volume facility (HRadj= 0.88, 95% CI = 0.80-0.98) were independent predictors of overall survival. Conclusions: Facility volume independently predicted guideline compliance in oral tongue cancer. Guideline compliance and treatment at a high case volume facility were predictors of overall survival. Clinicians should apply guideline compliant care regardless of practice setting and treatment at higher volume centers should be considered.

A prospective in silico analysis of interdisciplinary and interobserver spatial variability in post-operative target delineation of high-risk oral cavity cancers: Does physician specialty matter?

Background

The aim of this study was to determine the interdisciplinary agreement in identifying the post-operative tumor bed.

Methods

Three radiation oncologists (ROs), four surgeons, and three radiologists segmented post-operative tumor and nodal beds for three patients with oral cavity cancer. Specialty cohort composite contours were created by STAPLE algorithm implementation results for interspecialty comparison. Dice similarity coefficient and Hausdorff distance were utilized to compare spatial differentials between specialties.

Results

There were significant differences between disciplines in target delineation. There was unacceptable variation in Dice similarity coefficient for each observer and discipline when compared to the STAPLE contours. Within surgery and radiology disciplines, there was good consistency in volumes. ROs and radiologists have similar Dice similarity coefficient scores compared to surgeons.

Conclusion

There were significant interdisciplinary differences in perceptions of tissue-at-risk. Better communication and explicit description of at-risk areas between disciplines is required to ensure high-risk areas are adequately targeted.

Racial disparities in the choice of definitive treatment for squamous cell carcinoma of the oral cavity

BACKGROUND

Definitive surgery is recommended for oral cavity squamous cell carcinoma (SCC). The purpose of this study was to present our assessment of the disparities in treatment selection for oral cavity SCC.

METHODS

Non-Hispanic white and non-Hispanic black patients with oral cavity SCC were identified in the National Cancer Database (NCDB). Regression models were used to estimate relative risk (RR) of receiving surgery and absolute difference between non-Hispanic white and non-Hispanic black patients.

RESULTS

There were 82.3% of non-Hispanic white patients who received surgery, compared to 64.2% of non-Hispanic black patients (P < .001). The non-Hispanic black patients were less likely to receive surgery than non-Hispanic white patients (RR 0.87) with an absolute difference of 10.9%. The non-Hispanic black patients were significantly more likely to not be offered surgery (RR 1.42) and to refuse recommended surgery (RR 1.38) but not have a contraindication to surgery (RR 1.17).

CONCLUSION

The non-Hispanic black patients are less likely to receive or be recommended surgery for oral cavity SCC and are more likely to refuse surgery. Further study is needed to identify strategies to close this disparity.

Performance Improvement in Head and Neck Cancer

Performance improvement requires establishing a platform to set benchmarks and monitor the quality of care provided through quality indicators and metrics. This has long been recognized as critical to overall quality improvement and more recently, has become federally mandated. Here, we review recent studies evaluating performance in head and neck cancer care, from those spanning all phases of head and neck cancer care to others focused on head and neck surgical performance, including both national and departmental/institutional efforts.

Genome-wide gene-environment interaction in depression: A systematic evaluation of candidate genes: The childhood trauma working-group of PGC-MDD

Gene by environment (GxE) interaction studies have investigated the influence of a number of candidate genes and variants for major depressive disorder (MDD) on the association between childhood trauma and MDD. Most of these studies are hypothesis driven and investigate only a limited number of SNPs in relevant pathways using differing methodological approaches. Here (1) we identified 27 genes and 268 SNPs previously associated with MDD or with GxE interaction in MDD and (2) analyzed their impact on GxE in MDD using a common approach in 3944 subjects of European ancestry from the Psychiatric Genomics Consortium who had completed the Childhood Trauma Questionnaire. (3) We subsequently used the genome-wide SNP data for a genome-wide case-control GxE model and GxE case-only analyses testing for an enrichment of associated SNPs. No genome-wide significant hits and no consistency among the signals of the different analytic approaches could be observed. This is the largest study for systematic GxE interaction analysis in MDD in subjects of European ancestry to date. Most of the known candidate genes/variants could not be supported. Thus, their impact on GxE interaction in MDD may be questionable. Our results underscore the need for larger samples, more extensive assessment of environmental exposures, and greater efforts to investigate new methodological approaches in GxE models for MDD.

General Anesthesia Imposes Negative Effects on Heart Rate and Blood Pressure Regulation in Patients With a History of Head and Neck Radiation Therapy

BACKGROUND

Head and neck radiation therapy (HNRT) impairs baroreflex sensitivity, and it may potentiate the effects of anesthetics on heart rate (HR) and blood pressure (BP) regulation. Currently, the impacts of HNRT on HR and BP under anesthesia remain unclear.

METHODS

In this study, 472 patients with primary oral cavity or oropharyngeal cancer at all stages were examined. Half of the patients underwent HNRT plus surgery. The other half underwent surgery only and was matched with the treatment patients according to age, sex, and body mass index at a 1:1 ratio. The HRs and BPs in the 2 groups during anesthetic induction, skin incision, and emergence were compared retrospectively. A multivariable model of repeated measures with unstructured covariance structure was used to examine the associations of HNRT with intraoperative HRs and BPs after adjusting for baseline HR and BP, time, use of β-blockers, history of chemotherapy, and American Society of Anesthesiologists physical status score. BPs and HRs were collected every 5 minutes. The baseline HR and BP measurements were not included in the outcome vector and were only used as adjustment for baselines.

RESULTS

Compared with corresponding baseline values in controls, the baseline HR was significantly higher (P = .0012) and the baseline systolic BP was lower (P < .0001) in the treatment group. The baseline diastolic BP levels did not differ significantly (P = .6411). Fewer patients receiving HNRT than controls took β-blockers daily (17% vs 28%; P = .0041). Comparing the corresponding values in control and treatment groups, multivariable analysis revealed significant associations of HNRT with decreases in HR during anesthesia induction (-2.21 [95% confidence interval {CI}, -4.42 to -0.01]; P = .0492) and skin incision (-2.66 [95% CI, -5.16 to -0.16]; P = .0373) and of HNRT with decreases in systolic BP during anesthesia induction (-6.88 [95% CI, -10.99 to -2.78]; P = .0011) and skin incision (-15.87 [95% CI, -20.45 to -11.29]; P < .001). However, we observed a significant association of HNRT with decrease in diastolic BP only during skin incision (-6.50 [95% CI, -9.47 to -3.53]; P < .0001).

CONCLUSIONS

The significant finding in the study was that general anesthesia imposed a negative chronotropic effect on HR in the group given HNRT. Therefore, one should be watchful for bradycardia in these patients; particularly those with low BPs. Their hemodynamics may rapidly progress into an unstable status when bradycardia and hypotension develop altogether.

Cognitive function and patient-reported memory problems after radiotherapy for cancers at the skull base: A cross-sectional survivorship study using the Telephone Interview for Cognitive Status and the MD Anderson Symptom Inventory-Head and Neck Module

BACKGROUND

Using patient-reported and objective assessment tools, we sought to quantify cognitive symptoms and objective cognitive dysfunction in patients irradiated for skull base cancer.

METHODS

Participants were assessed using the Telephone Interview for Cognitive Status (TICS) and the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN), with subsequent analysis.

RESULTS

Of the 122 participants analyzed, the majority (63%) had no frank detectable cognitive impairment by TICS, with frank impairment in 6%. Overall, mean patient-reported problems with memory (MDASI_memory ) was 3.3 (SD ±2.66). On recursive partition analysis, the MDASI_memory cutoff point of ≥5 was associated with detectable cognitive impairment by TICS (logworth 1.69; P = .02), yet no MDASI_memory threshold was associated with unambiguous absence of impairment by TICS.

CONCLUSION

Approximately one third of patients had ambiguous results by TICS assessment, for whom more rigorous testing may be warranted. Moderate to severe levels of patient-reported memory complaints on the MDASI-HN module may have utility as a screening tool for cognitive dysfunction in this population.

Cost-effectiveness of pharmacogenetic-guided treatment: are we there yet?

Pharmacogenetics (PGx) has the potential to personalize pharmaceutical treatments. Many relevant gene-drug associations have been discovered, but PGx-guided treatment needs to be cost-effective as well as clinically beneficial to be incorporated into standard health-care. We reviewed economic evaluations for PGx associations listed in the US Food and Drug Administration (FDA) Table of Pharmacogenomic Biomarkers in Drug Labeling. We determined the proportion of evaluations that found PGx-guided treatment to be cost-effective or dominant over the alternative strategies, and estimated the impact on this proportion of removing the cost of genetic testing. Of the 137 PGx associations in the FDA table, 44 economic evaluations, relating to 10 drugs, were identified. Of these evaluations, 57% drew conclusions in favour of PGx testing, of which 30% were cost-effective and 27% were dominant (cost-saving). If genetic information was freely available, 75% of economic evaluations would support PGx-guided treatment, of which 25% would be cost-effective and 50% would be dominant. Thus, PGx-guided treatment can be a cost-effective and even a cost-saving strategy. Having genetic information readily available in the clinical health record is a realistic future prospect, and would make more genetic tests economically worthwhile.

Complications, hospital length of stay, and readmission after total laryngectomy

BACKGROUND

The purpose of this study was to describe the 30-day incidence of complications after total laryngectomy (TL) in a high-volume institution and their impact on the hospital length of stay (LOS) and readmission rates.

METHODS

A retrospective cohort study of all patients who underwent TL at The University of Texas MD Anderson Cancer Center from January 1, 2010 through June 30, 2013 was conducted. The patient demographics, treatment history, LOS, and 30-day post-TL complications and readmissions were extracted from the medical record. Univariate associations were analyzed, and stepwise backward selection methods were used to fit multivariate models.

RESULTS

Two hundred forty-five patients were included. Complications occurred in 83 patients (33.9%) and included 3 deaths (1.2%). Wound complications occurred in 53 patients (21.6%), and 34 were pharyngocutaneous fistulas (PCFs; 13.9% overall). Thirty-four patients (13.9%) were readmitted within 30 days. A multivariate analysis revealed the following: wound complications were associated with former (odds ratio [OR], 5.1; P = .03) and current smokers (OR, 5.8; P = .02), PCFs were associated with prior wide-field radiation (OR, 3.1; P = .01) but not prior narrow-field (larynx-only) radiation (OR, 1.4; P = .61), LOS was associated with the type of flap (P = .002) and postoperative hematomas (P = .05), and readmissions were associated with preoperative hypoalbuminemia (P = .003) and postoperative wound complications (P < .001).

CONCLUSIONS

Complications occurred in approximately one-third of TL patients and particularly in patients with poor wound-healing risk factors such as prior smoking and radiation. As expected, LOS was longer among reconstructed patients. Readmission was associated with hypoalbuminemia and postoperative wound complications. These data can inform quality improvement efforts and the counseling of high-risk patients undergoing TL. Cancer 2017;123:1760-1767. © 2016 American Cancer Society.

Development and Feasibility of a Specialty-Specific National Surgical Quality Improvement Program (NSQIP): The Head and Neck-Reconstructive Surgery NSQIP

IMPORTANCE

The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) serves the need for continual quality assessment in general surgery. Previously, no parallel mechanism specific to head and neck oncologic surgery existed.

OBJECTIVE

To address the need for continual quality assessment in subspecialty surgery by adapting the ACS NSQIP platform for complex head and neck oncologic surgical procedures.

DESIGN, SETTING, AND PARTICIPANTS

With an institutional ACS NSQIP team's guidance, surgeons from the departments of head and neck surgery and plastic and reconstructive surgery developed disease- and procedure-specific preoperative, intraoperative, and postoperative variables specific to head and neck surgery requiring reconstruction. Collection occurred with 100% sampling and standard ACS NSQIP 30-day follow-up. After a pilot period, long-term functional outcomes were added to this platform. A total of 312 patients underwent head and neck surgery requiring reconstruction at an academic medical center between August 1, 2012, and June 30, 2013.

EXPOSURES

Development of a specialty-specific head and neck surgery ACS NSQIP platform.

MAIN OUTCOMES AND MEASURES

The feasibility of adapting the ACS NSQIP platform to capture complex head and neck surgery metrics in all patients.

RESULTS

Head and neck surgery-specific preoperative, intraoperative, and postoperative variables were added to the ACS NSQIP platform and evaluated in 312 patients (201 [64.4%] male). Only 42 patients (13.5%) had no preoperative risk factors, and 136 (43.6%) had 3 or more risk factors. The mean (SD) duration of operation was 9.4 (3.0) hours (range, 1.7-19.3 hours). The mean (SD) postoperative length of stay was 7.9 (4.7) days (range, 1-40 days), 58 patients (18.6%) had an unplanned return to the operating room, 23 patients (7.4%) were readmitted within 30 days, and 3 patients (1.0%) died within 30 days. More than half of the patients (160 [51.3%]) did not experience a postoperative occurrence.

CONCLUSIONS AND RELEVANCE

To our knowledge, this is the first comprehensive complex oncologic surgery outcomes platform derived from ACS NSQIP methods. The initial pilot demonstrates the ability to systematically capture head and neck surgery-specific variables with complete sampling. With multi-institutional expansion, increased accrual, and long-term patient-reported outcomes, we hope to set risk-adjusted benchmarks that may underpin quality improvement efforts in complex head and neck surgery.

Effects of Office Interior Color on Workers' Mood and Productivity

The experiment was designed to examine the effects of a red versus a blue office environment on a typing task and mood. Empirical evidence in this area is sparse, but the prevailing view is that “warm” colors ate more arousing than “cool” colors. The 36 paid subjects were given the task of typing business forms for 20 min. in either a monochromatic red or blue office space and then asked to fill out the Eight State Questionnaire. In the second half of the experiment, subjects either returned to the same-colored office or moved to the different-colored office where the same procedure was followed but with alternate business forms and an alternate form of the questionnaire. Significant main effects found were for the number of errors made on the typing task; the subjects who moved to the different-colored office made more errors than those subjects who remained in the same-colored office. On the questionnaire, group differences were not statistically significant, but the mean anxiety and stress scores were higher for the subjects who remained in the red office, the mean depression score was higher for the subjects who remained in the blue office, and the mean arousal score was higher for those subjects who switched to the different-colored office.

Impact of intensive treatment and remission on health-related quality of life in early and established rheumatoid arthritis

Objectives

To establish if using intensive treatment to reduce synovitis and attain remission in active rheumatoid arthritis (RA) improves all aspects of health-related quality of life (HRQoL).

Methods

A secondary analysis of two randomised clinical trials (CARDERA and TACIT) was undertaken. CARDERA randomised 467 patients with early active RA to different disease-modifying antirheumatic drug (DMARD) regimens, including high-dose tapering corticosteroids. TACIT randomised 205 established patients with active RA to combination DMARDs (cDMARDs) or tumour necrosis factor-α inhibitors (TNFis). Short-Form 36 (SF-36) measured HRQoL across eight domains, generating physical (PCS) and mental (MCS) component summary scores. Linear regression evaluated 6-month intensive treatment impacts. Mean SF-36 scores, stratified by end point disease activity category, were compared with age/gender-matched population scores.

Results

In CARDERA, intensive corticosteroid treatment gave significantly greater improvements in PCS but not MCS scores relative to placebo. In TACIT, all eight SF-36 domains had improvements from baseline exceeding minimal clinically important differences with cDMARDs and TNFis. Significantly greater improvements with TNFi relative to cDMARDs were reported in PCS only (p=0.034), after adjusting for covariates. Remission provided the best SF-36 profiles, but scores in physical functioning, role physical and general health in both trials remained below normative values. Patient global assessment of disease activity had a greater association with HRQoL than other disease activity score (DAS28) components.

Conclusions

Intensive corticosteroid treatment in early RA improves physical but not mental health, relative to placebo. In established RA, cDMARDs and TNFi provide similar improvements in HRQoL. As remission optimises but fails to normalise HRQoL, a focus on treatment strategies targeting HRQoL is required.

Trial registration numbers

CARDERA was registered as ISRCTN 32484878. TACIT was registered as ISRCTN 37438295; pre-results.

Improving patient outcomes through multidisciplinary treatment planning conference

BACKGROUND

The purpose of this study was for us to determine National Comprehensive Cancer Network (NCCN) guideline-compliance of multidisciplinary conference (MDC) recommendations and actual treatment received, and to determine this impact on patient outcomes.

METHODS

We conducted a retrospective review of patients presented at MDC between January 1, 2006, and December 31, 2006, with previously untreated incident cancers.

RESULTS

We identified 232 patients, for whom MDC recommendations were NCCN guideline-compliant in 201 (86.6%). Actual treatment was NCCN guideline-compliant in 170 of 197 patients (86.3%). Adherence of MDC recommendations to NCCN guidelines was associated with superior overall survival (hazard ratio [HR] = 0.69; 95% confidence interval [CI] = 0.33-1.39; p = .3), as was guideline-compliance of actual treatment (HR = 0.6; 95% CI = 0.64-1.07; p = .07); congruence between MDC recommendations and actual treatment conferred a statistically significant overall survival benefit (HR = 0.49; 95% CI = 0.27-0.89; p = .02).

CONCLUSION

Our findings argue for patient-centered application of NCCN guidelines. Prospective evaluation will enable more timely identification of systematic NCCN guideline deviations that quality improvement interventions may address. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1820-E1825, 2016.

Favorable patient reported outcomes following IMRT for early carcinomas of the tonsillar fossa: Results from a symptom assessment study

BACKGROUND

A questionnaire-based study was conducted to assess long-term patient reported outcomes (PROs) following definitive IMRT-based treatment for early stage carcinomas of the tonsillar fossa.

METHODS

Participants had received IMRT with or without systemic therapy for squamous carcinoma of the tonsillar fossa (T1-2 and N0-2b) with a minimum follow-up of 2years. Patients completed a validated head and neck cancer-specific PRO instrument, the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN). Symptoms were compared between treatment groups of interest and overall symptom burden was evaluated.

RESULTS

Of 139 participants analyzed, 51% had received ipsilateral neck IMRT, and 62% single modality IMRT alone (no systemic therapy). There were no differences in mean severity ratings for the top-ranked individual symptoms or symptom interference for those treated with bilateral versus ipsilateral neck IMRT alone. However, 40% of those treated with bilateral versus 25% of those treated with ipsilateral neck RT alone reported moderate-to-severe levels of dry mouth (p=0.03). Fatigue, numbness/tingling, and constipation were rated more severe for those who had received systemic therapy (p<0.05 for each), but absolute differences were small. Overall, 51% had no more than mild symptom ratings across all 22 symptoms assessed.

CONCLUSIONS

The long-term patient reported symptom profile in this cohort of tonsil cancer survivors treated with definitive IMRT-based treatment showed a majority of patients with no more than mild symptoms, low symptom interference, and provides an opportunity for future comparison studies with other treatment approaches.
