Flap Reconstruction Results in Longer Overall Treatment Time in Patients Treated With Surgery and Adjuvant Radiotherapy for Carcinoma of the Oral Cavity and Larynx

OBJECTIVE

There is an inverse relationship between cancer cure and overall treatment time (OTT) in patients treated with surgical resection and radiotherapy (RT).

METHODS

OTT was evaluated based on the reconstruction procedure in 420 patients with oral cavity and larynx cancers treated with surgery and RT between 1991 and 2020.

RESULTS

With OTT >85 days, the difference between no versus yes flap reconstruction was ~20 percentage points and significant for all comparisons: primary closure (+/- skin graft), 49%, vs. rotation or free flap, 71% ( P <0.0001); primary closure (+/- skin graft), 49%, versus free flap without bone, 66% ( P =0.0358); and primary closure (+/- skin graft), 49%, versus free flap with bone, 82% ( P <0.0001).

CONCLUSIONS

The use of flap reconstructions results in substantial increases in OTT. Findings suggest a need to reevaluate current policies regarding the choice of reconstruction and starting RT sooner after surgery.

Socioeconomic Status, Length of Stay, and Postoperative Complications in Oral Cavity Squamous Cell Carcinoma

Background: Despite universal healthcare in Canada, low socioeconomic status (SES) has been associated with worse survival in oral cavity squamous cell carcinoma (OCSCC) patients. However, the relationship between SES and outcomes during the acute postoperative period is poorly defined. Hamilton, Ontario, presents a unique population with widely varying SES within the same geography. The objective of this study was to examine the relationship between SES, length of hospital stay (LOHS), and postoperative complications in OCSCC. Methods: Newly diagnosed OCSCC patients receiving primary surgical treatment from 2010 to 2014 were identified within a prospectively collected database. Inclusion criteria included age >18 years old, pathological diagnosis of oral cavity cancer, and primary surgical treatment with curative intent. Patients were excluded if they were undergoing palliative treatment or had previous head and neck surgery/radiotherapy. Postal codes were used to identify neighborhood-level socioeconomic variables via 2011 Canada Census data. Income quartiles were defined from groups of neighboring municipalities based on Canada Census definitions. Demographic, social, pathological, staging, and treatment data were collected through chart review. Results: One hundred and seventy-four patients were included in the final analysis. OCSCC patients with lower SES were more likely to be younger (P = .041), male (P = .040), have significant tobacco and alcohol use (P = .001), higher Charlson Comorbidity Index (CCI; P = .014), lower levels of education (P = .001), and have lower employment levels (P = .001). Lower SES patients had higher clinical tumor (P = .006) and clinical nodal (P = .004) staging and were more likely to receive adjuvant therapy (P = .001) and G-tubes (P = .001). Multivariable regression analysis showed that low SES was a statistically significant predictor of postoperative complications [β 2.50 (95% confidence interval (CI) 0.200, 3.17); P = .014] and LOHS [β 2.03 (95% CI 1.06, 2.99); P = .0001]. Tobacco and alcohol use, clinical tumor, and nodal stage, CCI, and planned adjuvant therapy were also statistically significant predictors of postoperative complications and LOHS (P < .05). Conclusion: Patients with lower SES have more advanced OCSCC disease with increased comorbidities that owes itself to more acute postoperative complications and LOHS within this study population. Patients with low SES should be identified as patients that require more support during their cancer treatment.

Hypothyroidism as an Independent Predictor of 30-day Readmission in Head and Neck Cancer Patients

OBJECTIVES

To define the role of hypothyroidism and other risk factors for unplanned readmissions after surgery for head and neck cancer.

STUDY DESIGN

Retrospective cohort study.

METHODS

The Nationwide Readmission Database (NRD) was used to identify patients who underwent surgery for mucosal head and neck cancer (oral cavity, oropharynx, larynx, and hypopharynx) between 2010 and 2017. Univariate and multivariate logistic regression were performed to determine patient, tumor, and hospital related risk factors for 30-day readmission. Readmitted patients were stratified by preoperative diagnosis of hypothyroidism to compare readmission characteristics.

RESULTS

For the 131,013 patients who met inclusion criteria, the readmission rate was 15.9%. Overall, 11.91% of patients had a preoperative diagnosis of hypothyroidism. After controlling for other variables, patients with a preoperative diagnosis of hypothyroidism had 12.2% higher odds of readmission compared to those without hypothyroidism (OR: 1.12, 1.03-1.22, p = 0.008). Patients with hypothyroidism had different reasons for readmission, including higher rates of wound dehiscence, fistula, infection, and electrolyte imbalance. Among readmitted patients, the length of stay for index admission (mean 10.5 days vs. 9.2 days, p < 0.001), readmission (mean 7.0 vs. 6.6 days, p = 0.05), and total hospital charge were higher for hypothyroid patients ($137,742 vs. $119,831, p < 0.001).

CONCLUSION

Hypothyroidism is an independent risk factor for 30-day readmission following head and neck cancer resection. Furthermore, hypothyroid patients are more likely to be readmitted for wound complications, infection, and electrolyte imbalance. Targeted interventions should be considered for hypothyroid patients to decrease readmission rates and associated patient morbidity, potentially leading to earlier initiation of adjuvant treatment.

Enhanced recovery after surgery, current, and future considerations in head and neck cancer

Objectives

Review of the current and relevant literature to develop a list of evidence-based recommendations that can be implemented in head and neck surgical practices. To provide rationale for the multiple aspects of comprehensive care for head and neck surgical patients. To improve postsurgical outcomes for head and neck surgical patients.

Methods

Extensive review of the medical literature was performed and relevant studies in both the head and neck surgery and other surgical specialties were considered for inclusion.

Results

A total of 18 aspects of perioperative care were included in this review. The literature search included 276 publications considered to be the most relevant and up to date evidence. Each topic is concluded with recommendation grade and quality of evidence for the recommendation.

Conclusion

Since it's conception, enhanced recovery after surgery (ERAS) protocols have continued to push for comprehensive and evidence based postsurgical care to improve patient outcomes. Head and neck oncology is one of the newest fields to develop a protocol. Due to the complexity of this patient population and their postsurgical needs, a multidisciplinary approach is needed to facilitate recovery while minimizing complications. Current and future advances in head and neck cancer research will serve to strengthen and add new principles to a comprehensive ERAS protocol.

Factors Impacting Discharge Destination Following Head and Neck Microvascular Reconstruction

OBJECTIVE

Determine which variables impact postoperative discharge destination following head and neck microvascular free flap reconstruction.

STUDY DESIGN

Retrospective review of prospectively collected databases.

METHODS

Consecutive patients undergoing head and neck microvascular free flap reconstruction between January 2010 and December 2019 (n = 1972) were included. Preoperative, operative and postoperative variables were correlated with discharge destination (home, skilled nursing facility [SNF], rehabilitation facility, death).

RESULTS

The mean age of patients discharged home was lower (60 SD ± 13, n = 1450) compared to those discharged to an SNF (68 SD ± 14, n = 168) or a rehabilitation facility (71 SD ± 14, n = 200; p < 0.0001). Operative duration greater than 10 h correlated with a higher percentage of patients being discharged to a rehabilitation or SNF (25% vs. 15%; p < 0.001). Patients were less likely to be discharged home if they had a known history of cardiac disease (71% vs. 82%; p < 0.0001). Patients were less likely to be discharged home if they experienced alcohol withdrawal (67% vs. 80%; p = 0.006), thromboembolism (59% vs. 80%; p = 0.001), a pulmonary complication (46% vs. 81%; p < 0.0001), a cardiac complication (46% vs. 80%; p < 0.0001), or a cerebral vascular event (25% vs. 80%; p < 0.0001). There was no correlation between discharge destination and occurrence of postoperative wound infection, salivary fistula, partial tissue necrosis or free flap failure. Thirty-day readmission rates were similar when stratified by discharge destination.

CONCLUSION

There was no correlation with the anatomic site, free flap donor selection, or free flap survival and discharge destination. Patient age, operative duration and occurrence of a medical complication postoperatively did correlate with discharge destination.

Association Between Insurance Type and Outcomes of Reconstructive Head and Neck Cancer Surgery

OBJECTIVES/HYPOTHESIS

Although the benefits of expanding health insurance coverage are clear, there are limited studies comparing the different types of insurance. This study aims to determine the association between insurance type and outcomes in patients with head and neck cancer undergoing reconstructive surgery in the United States.

METHODS

Population-based cross-sectional study of the 2012-2014 National Inpatient Sample. We identified 1,314 patients with head and neck cancers undergoing tumor ablative surgery followed by pedicled or free flap reconstruction of oncologic defects. Insurance type was classified as private, Medicare, Medicaid, self-pay, or other. The primary outcome was extended length of stay (LOS), defined as greater than 14 days, which represented the 75th percentile of the study sample. Secondary outcomes included acute medical complications, surgical complications, morbidities, and costs. Analyses were adjusted for gender, geographic location, and various medical comorbidities.

RESULTS

In univariate analysis, insurance type was associated with extended LOS (P = .001), medical complications (P = <.001), and mortalities (P = .020). After controlling for other covariates in the multivariate analysis, compared to private insurance, Medicare and Medicaid were both associated with significantly higher odds of extended LOS (adjusted odds ratio [OR] [95% confidence interval (CI)] = 1.73 [1.09-2.76] and 2.22 [1.38-3.58], respectively). Medicare was associated with significantly higher odds of medical complications, but Medicaid was not (adjusted OR [95% CI] = 1.53 [1.02-2.31] and 1.64 [0.97-2.78], respectively).

CONCLUSIONS

Medicaid and Medicare were independently associated with extended LOS after reconstructive head and neck cancer surgery. Medicare was associated with higher rates of medical complications. Efforts to address LOS should target care planning and coordination.

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.

LigaSure small jaw versus conventional neck dissection: a systematic review and meta-analysis

Background

Neck dissection has a central role in the management of head and neck cancers. This systematic review aimed to compare the intraoperative and postoperative parameters between conventional and LigaSure Small Jaw (LSJ)-assisted neck dissection.

Methods

PubMed (MEDLINE), Embase, and the Cochrane Library were searched.

independently by two authors for relevant articles comparing the outcomes of conventional and LSJ-assisted neck dissection. Data from each study were extracted, and a random-effects model was used in the pooled analysis.

Results

Compared with conventional techniques, LSJ-assisted neck dissection was associated with a significantly reduced operative time. The rates of postoperative hematoma, infection, amount of intraoperative blood loss, the length of hospital stay and the drainage amount showed no significant intergroup differences.

Conclusions

The meta-analysis provides evidence that properly using LSJ may reduce the operative time compared with that of conventional techniques. Surgeons may consider using LSJ in neck dissection according to personal experiences.

Pilot of the Patient Concerns Inventory - Ward Discharge in Patients following major reconstructive surgery for head and neck cancer

Planning discharge from hospital following microvascular free-tissue surgery can be complex and challenging. Planning involves the patient, carers and multiple health professionals. Poor communication and expectations can delay discharge or give a suboptimal discharge process. It was hypothesised that prompt-list modelled along the principals of the Patient Concerns Inventory (PCI) could be help in discharge planning. The aim of this study was to define the items and format of a PCI-Ward Discharge (PCI-WD) and undertake a small pilot. Items appropriate for the PCI-WD were formulated through discussion with patients, carers, ward staff, Head and Neck Clinical Nurse Specialists, and clinicians. The pilot took place over 3 months from December 2019 through February 2020. Audit approval was given by the hospital Audit Department. The PCI-WD comprises 43 items. Items from existing PCIs for use at diagnosis and follow-up consultations were reduced in number and 38 new or modified items added; 6 treatment related, 5 social care and social well-being, 4 psychological, emotional and spiritual well-being, 7 physical and functional well-being and 16 discharge related. The pilot involved 14 free-tissue transfer patients, 7 male, 7 female, with age range 57 to 87 and average age 72. Eight PCI-WD were returned. PCI-WD items identified most frequently were ‘surgery site other than head/neck’, ‘when do I come back to hospital’, ‘dental check-up/oral health care’ and ‘diet/eating’. Early findings suggest that PCI-WD could be a useful tool in aiding the discharge process. Further evaluation is required.

Early discharge after free-tissue transfer does not increase adverse events

INTRODUCTION

Demonstrate that carefully selected free flap patients may be discharged early after surgery without increasing the rates of postoperative complications or readmissions.

METHODS

Based on a published article in Laryngoscope 2016 of 51 free-tissue transfers, a retrospective chart review was performed on an expanded cohort who underwent free-tissue transfer for head and neck reconstruction between February 2010 and May 2018 and discharged by postoperative day 3.

RESULTS

101 patients who underwent 104 free flaps with average age of 56 (3-84) years old were reviewed. Free flap indications included orbital and maxillary defects (n = 22), palatal defects (n = 16), nasal and septal defects (n = 16), cranioplasty and scalp defects (n = 16), mandibular defects due to osteoradionecrosis (n = 14), facial contouring and parotid defects (n = 12), and complex postsurgical and radiotherapy wounds or fistula closure (n = 8). Free flaps performed were anterolateral thigh (n = 97), radial forearm (n = 2), serratus (n = 2), latissimus (n = 1), fibula (n = 1) and supraclavicular (n = 1). The recipient vessels used via minimal access approaches were facial (n = 43), superficial temporal (n = 29), angular (n = 20) and others. There were 3 flap failures (2.9%) recognized in follow-up. No flap failures or perioperative complications were associated with early discharge. There were only 2 patients readmitted and 1 watched in observation within 30 days postoperatively.

CONCLUSION

An updated review of our institutional experience with more than double the cohort size substantiates previous conclusions that early discharge after free-tissue transfer is a safe option in select patients. Moreover, earlier discharge is a critical management choice that reduces cost and decreases hospital-related adverse events.
