RESUMO
Head and neck cancer (HNC) treatment often consists of major surgery followed by adjuvant therapy, which can result in treatment-related side effects, decreased physical function, and diminished quality of life. Perioperative nutrition interventions and early mobilization improve recovery after HNC treatment. However, there are few studies on prehabilitation that include exercise within the HNC surgical care pathway. We have designed a multiphasic exercise prehabilitation intervention for HNC patients undergoing surgical resection with free flap reconstruction. We will use a hybrid effectiveness-implementation study design guided by the RE-AIM framework to address the following objectives: (1) to evaluate intervention benefits through physical function and patient-reported outcome assessments; (2) to determine the safety and feasibility of the prehabilitation intervention; (3) to evaluate the implementation of exercise within the HNC surgical care pathway; and (4) to establish a post-operative screening and referral pathway to exercise oncology resources. The results of this study will provide evidence for the benefits and costs of a multiphasic exercise prehabilitation intervention embedded within the HNC surgical care pathway. This paper describes the study protocol design, multiphasic exercise prehabilitation intervention, planned analyses, and dissemination of findings.

(1) Background: To compare oncologic outcomes of South Asian (SA) patients treated for oral squamous cell carcinoma (OSCC) to the general population. (2) Methods: Adult patients who underwent surgical resection of OSCC +/- adjuvant treatment between 2009 and 2022 (N = 697) at a regional cancer centre in Canada were included. SA patients, identified using a validated method, were compared to non-SA patients. Kaplan-Meier methods were used to compare the primary outcomes, disease-specific survival (DSS) and recurrence-free survival (RFS) across baseline univariate characteristics, including betel nut consumption. Median follow-up time was 36.4 months. Cox proportional hazard models were used to identify independent predictors of survival with significance set at p < 0.05. (3) Results: SA patients (9% of cohort, N = 64) were significantly younger and had lower rates of smoking and alcohol consumption compared to non-SA patients (p < 0.05). SA patients had a two-fold higher risk of recurrence and significantly worse disease-specific survival, even after adjusting for stage and high-risk features [RFS: HR 2.01 (1.28-3.14), DSS: HR 1.79 (1.12-2.88)]. The consumption of betel nut was not associated with outcomes. (4) Conclusions: SA patients had significantly worse oncologic outcomes, even after controlling for known predictors of poor prognosis. These findings are novel and can inform personalized treatment decisions and influence public health policies when managing patients with different ethnic backgrounds.
RESUMO
OBJECTIVE: To describe the success rate, complications, and functional outcomes of patients who are treated with osteocutaneous free tissue transplantation for grade 4 mandibular osteoradionecrosis (ORN). DESIGN: Retrospective case series. SETTING: Tertiary care academic medical center. PATIENTS: Twelve patients (8 males, 4 females; mean age, 57.6 years) with grade 4 mandibular ORN. Three patients (25%) had a history of primary radiotherapy, two (17%) had previous concurrent chemoradiation, and seven (58%) had undergone postoperative adjuvant radiotherapy. Ten patients (83%) had previous major ablative surgery to treat the primary tumor and five (50%) had been reconstructed with a free tissue transplant prior to the onset of ORN. INTERVENTIONS: All patients underwent reconstruction with an osteocutaneous free tissue transplant for grade 4 mandibular ORN between 1999 and 2006. MAIN OUTCOME MEASURES: Successful treatment of mandibular ORN; major, minor, and late complications; gastrostomy tube (G-tube) dependence; speech and swallowing scores. RESULTS: Grade 4 mandibular ORN was successfully treated in eight (73%) evaluable patients. One patient (8%) died of a second primary tumor before the 12-month assessment. Eight patients (67%) had a major complication, three (25%) had a minor complication, and nine (75%) had a late complication. Three of the five G-tube- dependent patients prior to mandibular reconstruction were able to discontinue the use of their G-tube. Seven of the eight successfully treated patients maintained their nutrition by mouth. Median "range of liquids" score was 6/6 (range, 4 to 6). Median "range of solids" score was 4/6 (range, 3 to 6). Median "understandability of speech" score was 4/5 (range, 2 to 5). CONCLUSIONS: Grade 4 mandibular ORN was treated successfully with an osteocutaneous free tissue transfer in eight evaluable patients (73%). In successfully treated patients, median speech/swallowing scores were highly functional, but the remaining radiated soft tissue resulted in higher local wound complications and a modified diet.

Importance: Head and neck oncological resection and reconstruction is a complex process that requires multidisciplinary collaboration and prolonged operative time. Numerous factors are associated with operative time, including a surgeon's experience, team familiarity, and the use of new technologies. It is paramount to evaluate the contribution of these factors and modalities on operative time to facilitate broad adoption of the most effective modalities and reduce complications associated with prolonged operative time. Objective: To examine the association of head and neck cancer resection and reconstruction interventions with operative time. Design, Setting, and Participants: This large cohort study included all patients who underwent head and neck oncologic resection and free flap-based reconstruction in Calgary (Alberta, Canada) between January 1, 2007, and March 31, 2020. Data were analyzed between November 2021 and May2022. Interventions: The interventions that were implemented in the program were classified into team-based strategies and the introduction of new technology. Team-based strategies included introducing a standardized operative team, treatment centralization in a single institution, and introducing a microsurgery fellowship program. New technologies included use of venous coupler anastomosis and virtual surgical planning. Main Outcomes and Measures: The primary outcome was mean operative time difference before and after the implementation of each modality. Secondary outcomes included returns to the operating room within 30 days, reasons for reoperation, returns to the emergency department or readmissions to hospital within 30 days, and 2-year and 5-year disease-specific survival. Multivariate regression analyses were performed to examine the association of each modality with operative time. Results: A total of 578 patients (179 women [30.9%]; mean [SD] age, 60.8 [12.9] years) undergoing 590 procedures met inclusion criteria. During the study period, operative time progressively decreased and reached a 32% reduction during the final years of the study. A significant reduction was observed in mean operative time following the introduction of each intervention. However, a multivariate analysis revealed that team-based strategies, including the use of a standardized nursing team, treatment centralization, and a fellowship program, were significantly associated with a reduction in operative time. Conclusions: The results of this cohort study suggest that among patients with head and neck cancer, use of team-based strategies was associated with significant decreases in operative time without an increase in complications.

NTRK gene fusions are rare oncogenic driver mutations that can be found in a broad range of neoplasms. In secretory carcinoma (SC), ETV6-NTRK3 gene fusion is seen in a majority of the cases and represents a druggable target for patients with advanced disease in the absence of a currently accepted standard of care. In our case, we describe a patient with recurrent, metastatic SC treated with first line entrectinib with clinically meaningful, durable ongoing response after 49 months. The patient experienced grade 1 fatigue, dysgeusia, skin sensitivity, arthralgias, an increase in serum creatinine, and weight-gain as well as grade 2 hypotension which resolved after a dose reduction. Entrectinib is a well-tolerated treatment with the potential for durable responses and TRK inhibition should be considered the standard of care in SC and other NTRK gene fusion-positive advanced neoplasms without acceptable alternative treatment options.

Objective: To present clinical outcomes of the prospective implementation of the 2015 American Thyroid Association (ATA) guidelines for the management of thyroid nodules and differentiated thyroid cancer (DTC) using the modified ATA recurrence risk (RR) stratification system. Methods: We prospectively analyzed 612 patients with DTC treated between April 2017 and December 2021 in Calgary, Alberta. Each patient was prospectively assigned a modified ATA RR and American Joint Committee Cancer 8th edition stage. Initial risk stratification and consideration of the 2015 ATA guidelines guided surgical management as well as the indication for and dose of radioiodine (RAI) and other adjuvant therapies. Patients were assessed for their response to treatment (RTT) at 2-years postoperatively. Results: There were 479 patients who had 2-year follow-up data and were included in the study. Of these patients, there were 253 (53%) low-, 129 (27%) intermediate-, and 97 (20%) high-RR patients. Of these, 227 patients (47%) underwent total thyroidectomy (TTX) plus RAI, 178 (37%) underwent TTX only, and 74 (16%) underwent lobectomy. The RTT at 2 years was excellent for 89% (66) of patients with lobectomy, 84% (149) for TTX only, and 53% (121) for TTX plus RAI. Among 253 patients who were deemed low RR, 85% (216) had excellent RTT, 13% (32) indeterminate RTT, 2% (4) biochemical incomplete RTT, and 1 patient had structural incomplete RTT. The intermediate RR group had the following RTT outcomes: 64% (83) excellent, 23% (30) indeterminate, 6% (7) biochemical incomplete, and 7% (9) structural incomplete. The high RR group had the worst RTT outcomes, with 38% (37) excellent, 19% (18) indeterminate, 10% (10) biochemical incomplete, and 33% (32) structural incomplete RTT. Conclusions: The 2015 ATA RR stratification system is useful for predicting disease status at 2-year post-treatment in patients with DTC. The 2015 ATA guidelines and modified ATA RR stratification treatment recommendations may reduce thyroid cancer overtreatment by including lobectomy as a definitive treatment option for low-risk thyroid cancers and selective use of RAI for intermediate and high-risk patients.

Head and neck cancer (HNC) surgical patients experience a high symptom burden. Multiphasic exercise prehabilitation has the potential to improve patient outcomes, and to implement it into the care pathway, the perspectives of patients and healthcare providers (HCPs) must be considered. The purpose of this study was thus to gather feedback from HNC surgical patients and HCPs on building exercise into the standard HNC surgical care pathway. Methods: Semi-structured interviews were conducted with patients and HCPs as part of a feasibility study assessing patient-reported outcomes, physical function, and in-hospital mobilization. Interview questions included satisfaction with study recruitment, assessment completion, impact on clinical workflow (HCPs), and perceptions of a future multiphasic exercise prehabilitation program. This study followed an interpretive description methodology. Results: Ten patients and ten HCPs participated in this study. Four themes were identified: (1) acceptability and necessity of assessments, (2) the value of exercise, (3) the components of an ideal exercise program, and (4) factors to support implementation. Conclusion: These findings highlight the value of exercise across the HNC surgical timeline from both the patient and the HCP perspective. Results have informed the implementation of a multiphasic exercise prehabilitation trial in HNC surgical patients.

BACKGROUND: Physician opioid-prescribing patterns have significant impacts on the current opioid crisis. Patients who use opioids in the postoperative period are at risk of developing chronic postoperative opioid use. This study determined the rate of chronic postoperative opioid use among head and neck cancer patients undergoing primary surgery with free-flap reconstruction. Additionally, this study identified major risk factors associated with the development of chronic postoperative opioid use. METHODS: A retrospective chart review was performed for all adults (age ≥ 18 years) undergoing primary head and neck surgical resection with free-flap reconstruction between January 2008 and December 2015. Patients were identified from a prospectively collected database, Otobase™. Data from the provincial drug insurance program were used to capture drug dispensing information to determine chronic opioid use at 3- and 12-months postoperatively. Data extracted from Otobase™ included patient demographics, social habits, clinical stage, pathological stage, type of surgery, and adjuvant treatment. RESULTS: The total cohort was comprised of 212 patients. Chronic opioid use at 3- and 12- months postoperatively was observed in 136 (64%) and 116 (55%) patients, respectively. Of the 212 patients, 85 patients (40%) were identified as preoperative opioid users and 127 were opioid naïve (60%). Of the 85 patients who were preoperative opioid users, 70 (82%) and 63 (77%) patients continued to use opioids 3- and 12-months postoperatively, respectively. The proportion of opioid-naïve patients who were using opioids at 3- and 12-months postoperatively was 52% (66 patients) and 42% (53 patients), respectively. Identified risk factors included preoperative opioid use, prior tobacco use, advanced pathologic T-stage, and adjuvant treatment. CONCLUSIONS: Among head and neck cancer patients that have undergone major resection with free-flap reconstruction, the prevalence of chronic postoperative opioid users was considerable. Identified risk factors included preoperative opioid use, prior tobacco use, tumor stage, and adjuvant treatment.

BACKGROUND: Close margins influence treatment and outcome in patients with oral squamous cell carcinoma (OSCC). This study evaluates 187 cases of surgically treated OSCC regarding the impact of close margins on recurrence-free survival (RFS) and disease-specific survival (DSS). METHODS: Predictors of worsened outcome were identified using Kaplan-Meier analysis and multivariate Cox regression analysis. RESULTS: Tumour size [HR:1.70(0.95-3.08)], nodal status [HR:2.15(1.00-4.64)], presence of extracapsular spread (ECS) [HR:6.36(2.41-16.74)] and smoking history [HR:2.87(1.19-6.86)] were associated with worsened RFS. Similar factors were associated with worsened DSS. Close margins did not influence RFS or DSS. CONCLUSIONS: While most conventional risk factors for OSCC conferred a worsened outcome, close margins did not. One explanation for this would be that close margins (< 5 mm) are equivalent to clear margins and the cutoff definition for a close margin should be re-evaluated. Lack of standardized pathology could also reduce accuracy of reporting of close surgical margins.

Postoperative opioid use has been linked to the subsequent development of opioid dependency. Multimodal analgesia (MMA) can reduce the use of opioids in the postoperative period, but MMA has not been well-studied after major head and neck surgery. Our goal is to explore the association between MMA and postoperative opioid use and pain control in patients undergoing major head and neck surgery. We performed a retrospective study in adult (age ≥ 18 years) patients undergoing primary head and neck cancer resection with free-flap reconstruction. All patients were treated using an established care pathway. The baseline group was treated between January 2015-December 2015 (n = 41), prior to the implementation of MMA, and were compared to an MMA-treated cohort treated between December 2017-June 2019 (n = 97). The primary outcome was the proportion of opioids prescribed and oral morphine equivalents (OMEs) consumed during the hospitalization. The secondary outcome was pain control. We found that the post-MMA group consumed fewer opioids in the postoperative period compared to the pre-MMA group. Prior to post-operative day (POD) 6, pain control was better in the post-MMA group; however, the pain control lines intersect on POD 6 and the pre-MMA group appeared to have better pain control from PODs 7-10. In conclusion, our data suggest MMA is an effective method of pain control and opioid reduction in patients undergoing surgery for head and neck cancer with free flap reconstruction. MMA use was associated with a significant decrease in the quantity of opioids consumed postoperatively. The MMA protocol was associated with improved pain management early in the postoperative course. Finally, the MMA protocol is a feasible method of pain control and may reduce the adverse side effects associated with opioid use.
RESUMO
Surgery with free flap reconstruction is a standard treatment for head and neck cancer (HNC). Because of the complexity of HNC surgery, recovery can be challenging, and complications are common. One of the foundations of enhanced recovery after surgery (ERAS) is early postoperative mobilization. The ERAS guidelines for HNC surgery with free flap reconstruction recommend mobilization within 24 h. This is based mainly on evidence from other surgical disciplines, and the extent to which mobilization within 24 h improves recovery after HNC surgery has not been explored. This retrospective analysis included 445 patients from the Calgary Head and Neck Enhanced Recovery Program. Mobilization after 24 h was associated with more complications of any type (OR = 1.73, 95% CI [confidence interval] = 1.16-2.57) and more major complications (OR = 1.76; 95% CI = 1.00-3.16). When accounting for patient and clinical factors, mobilization after 48 h was a significant predictor of major complications (OR = 2.61; 95% CI = 1.10-6.21) and prolonged length of stay (>10 days; OR = 2.85, 95% CI = 1.41-5.76). This comprehensive analysis of the impact of early mobilization on postoperative complications and length of stay in a large HNC cohort provides novel evidence supporting adherence to the ERAS early mobilization recommendations. Early mobilization should be a priority for patients undergoing HNC surgery with free flap reconstruction.
RESUMO
One of the foundational elements of enhanced recovery after surgery (ERAS) guidelines is early postoperative mobilization. For patients undergoing head and neck cancer (HNC) surgery with free flap reconstruction, the ERAS guideline recommends patients be mobilized within 24 h postoperatively. The objective of this study was to evaluate compliance with the ERAS recommendation for early postoperative mobilization in 445 consecutive patients who underwent HNC surgery in the Calgary Head and Neck Enhanced Recovery Program. This retrospective analysis found that recommendation compliance increased by 10% despite a more aggressive target for mobilization (from 48 to 24 h). This resulted in a decrease in postoperative mobilization time and a stark increase in the proportion of patients mobilized within 24 h (from 10% to 64%). There was a significant relationship between compliance with recommended care and time to postoperative mobilization (Spearman's rho = -0.80; p < 0.001). Hospital length of stay was reduced by a median of 2 days, from 12 (1QR = 9-16) to 10 (1QR = 8-14) days (z = 3.82; p < 0.001) in patients who received guideline-concordant care. Engaging the clinical team and changing the order set to support clinical decision-making resulted in increased adherence to guideline-recommended care for patients undergoing major HNC surgery with free flap reconstruction.
RESUMO
SUMMARY: Patient-reported outcomes regarding donor-site morbidity and quality of life for the fibula free flap in head and neck reconstruction patients have not been studied. The authors reviewed and identified patients who had undergone head and neck reconstruction using a fibula free flap (2011 to 2016). Patients were assessed via physical examination and two patient-reported outcomes questionnaires: the Foot and Ankle Outcome Score (score range, 0 to 100) and the Pain Disability Questionnaire (score range, 0 to 100). Quantitative data were analyzed with appropriate statistical tests. Semistructured interviews exploring donor-site challenges were performed and analyzed using thematic analysis. Seventeen patients agreed to participate. Their mean age was 62 years (range, 41 to 81 years). Mean follow-up was 38 months (range, 12 to 65 years). Mean perceived level of function compared to baseline was 67 percent. Mean scores for the Foot and Ankle Outcome Score subscales were 84.6 (pain), 80.5 (symptoms), 86.7 (activities of daily living), 67.7 (sport), and 65.6 (quality of life). The mean Pain Disability Questionnaire score was 26.3 (mild/moderate perceived disability). Higher perceived level of function was associated with higher Foot and Ankle Outcome Score values (pain, symptoms, and activities of daily living, p < 0.05). Donor limbs had decreased range of motion and manual muscle testing scores compared with their contralateral limbs (p < 0.05). Lack of ankle support and balance, resulting in limitations and aversions to daily and sporting activities, were the most common themes regarding donor-site challenges. In conclusion, patients who have undergone fibula free flap harvest struggle with ankle support and balance and face functional difficulties that have an impact on their quality of life. Multidisciplinary approaches for targeted rehabilitation after fibula free flap harvest should be explored to determine the impact on patients' quality of life.

Few studies have evaluated vascularized nerve grafts (VNGs) for facial nerve (CNVII) reconstruction. We sought to evaluate long-term outcomes for CNVII recovery following reconstruction with VNGs. A retrospective review of all patients at a tertiary centre who underwent radical parotidectomy and immediate CNVII reconstruction with VNGs was performed (January 2009-December 2019). Preoperative demographics, perioperative factors (flap type, source of VNGs), and postoperative factors [complications, adjuvant therapy, revisionary procedures, length of follow-up, and CNVII function via the House-Brackmann scale (HB)] were collected. Data were summarized qualitatively. Twelve patients (Mage = 53 ± 18 years) with a mean follow-up of 33 (± 23) months were included. Six patients underwent reconstruction with a radial forearm flap and dorsal sensory branches of the radial nerve. Six patients underwent reconstruction with an anterolateral thigh flap and only deep motor branches of the femoral nerve to the vastus lateralis (n = 4) or combined with the lateral femoral cutaneous nerve (n = 2). Two patients regained nearly normal function (HB = 2). Eight patients regained at least resting symmetry (HB = 3 for n = 7; HB = 4 for n = 1). One patient regained a flicker of movement (HB = 5). One patient did not regain function (HB = 6). Six patients had static revision procedures to improve symmetry. Five patients had disease recurrence; 3 died from their disease. VNGs offer a practical and viable addition to the CNVII reconstruction strategy, and result in good functional recovery with acceptable donor site deficits. The associated adipofascial component of these flaps can also augment the soft tissue defect left after tumor ablation.
RESUMO
Background: The traditional management of papillary thyroid cancer (PTC) is thyroidectomy (total or partial removal of the thyroid). Active surveillance (AS) may be considered as an alternative option for small, low risk PTC. AS involves close follow-up (including regularly scheduled clinical and radiological assessments), with the intention of intervening with surgery for disease progression or patient preference. Methods: This is a protocol for a prospective, observational, long-term follow-up multi-centre Canadian cohort study. Consenting eligible adults with small, low risk PTC (< 2cm in maximal diameter, confined to the thyroid, and not immediately adjacent to critical structures in the neck) are offered the choice of AS or surgery for management of PTC. Patient participants are free to choose either option (AS or surgery) and the disease management course is thus not assigned by the investigators. Surgery is provided as usual care by a surgeon in an institution of the patient's choice. Our primary objective is to determine the rate of 'failure' of disease management in respective AS and surgical arms as defined by: i) AS arm - surgery for progression of PTC, and ii) surgical arm - surgery or other treatment for disease persistence or progression after completing initial treatment. Secondary outcomes include long-term thyroid oncologic and treatment outcomes, as well as patient-reported outcomes. Discussion: The results from this study will provide long-term clinical and patient reported outcome evidence regarding active surveillance or immediate surgery for management of small, low risk PTC. This will inform future clinical trials in disease management of small, low risk papillary thyroid cancer. Registration details: This prospective observational cohort study is registered on clinicaltrials.gov (NCT04624477), but it should not be considered a clinical trial as there is no assigned intervention and patients are free to choose either AS or surgery.

Background: The extent of initial surgical resection for low-risk papillary thyroid cancer (PTC) remains debatable. Since the 2015 American Thyroid Association (ATA) guidelines, several retrospective studies have reported that 40-60% of patients initially treated with lobectomy would require a completion thyroidectomy (CTx) due to high-risk pathological features (HRFs). These studies are limited by variable preoperative stratification and inability to quantify the value of intraoperative assessment. The study objectives were to determine whether diligent preoperative and intraoperative assessment improves the appropriateness of initial surgery for low-risk PTCs and whether varying the criteria for lobectomy reduces the need for CTx. Methods: A prospectively collected province-wide database was analyzed over a 10-year period (2008-2017) for patients who underwent a total thyroidectomy (TT) for PTC without preoperative HRFs. All patients had preoperative ultrasound and fine-needle aspirates. Unique to this database are mandatory synoptic operative fields that identify intraoperative risk factors such as positive lymph nodes and local invasion. Results: In total, 74% of patients (709/959) were deemed eligible for lobectomy. Of those eligible, 149 (21%) had intraoperative risk factors that would necessitate conversion to TT at the initial operation. A further 209 (30%) would require CTx due to HRFs on final pathology. Varying the preoperative criteria for lobectomy did not significantly affect intraoperative conversion or CTx rates. Conclusions: Although intraoperative assessment reduced the need for CTx in 21%, up to 30% of patients would still require a second operation. Altering the preoperative criteria does not influence this outcome. Patients deemed eligible for lobectomy should be informed that despite careful pre- and intraoperative assessment, there is up to a 30% risk of requiring CTx.

Virtual surgical planning (VSP) has improved the accuracy and efficiency of craniofacial reconstruction using the osteocutaneous free fibula flap. Despite this, challenges remain in translating the VSP to a real-world construct due to small changes that can occur after osteotomies of the mandible or maxilla. Poor execution of the VSP can lead to malocclusion, undesirable aesthetics, or poor bony contact at the sites of osteosynthesis. We describe a novel technique using Selective LASER Melted plates to achieve maximum control and accuracy of complex, virtually planned reconstructions of the mandible and maxilla.
RESUMO
BACKGROUND: Our study quantifies the effectiveness of perioperative pain control in a cohort of patients undergoing major head and neck surgery with free flap reconstruction. Our long-term goal is to improve pain control and thereby increase mobility, decrease postoperative complications and decrease hospital stay. METHODS: A retrospective analysis was performed at a tertiary, academic head and neck surgical oncology program in Calgary, Alberta, Canada from January 1, 2015 - December 31, 2015. Pain scores were recorded prospectively. Primary outcomes were frequency of postoperative pain assessments and pain intensity using the numeric rating scale. RESULTS: The cohort included 41 patients. Analysis was limited to pain scores recorded from postoperative days 1-14. There was an average of 7.3 pain measurements per day (SD 4.6, range 1-24) with the most frequent monitoring on postoperative days 1-4. Median pain scores ranged from 0 to 4.5 with the highest median score on postoperative day 6. The daily maximum pain scores recorded ranged from 8 to 10 with scores of 10 recorded on postoperative days 1, 2, 3, 5, 7, 8, and 10. Patients most frequently had inadequate pain control on postoperative days 1, 2, 4, and 5 with the majority occurring on postoperative day 1. CONCLUSIONS: Postoperative pain control could be improved at our centre. The frequency of pain assessments is also highly variable. Ongoing measurement, audit, and feedback of analgesic protocol effectiveness is an excellent first step in improving perioperative pain management in patients undergoing major head and neck cancer surgery with free flap reconstruction.

The differential diagnosis and malignancy risk stratification of thyroid nodules requires multidisciplinary expertise and knowledge of both local ultrasonography practices and the local malignancy rates for a given fine-needle aspiration (FNA) result. Even in such a multidisciplinary setting, FNA cytology has the inherent limitation that indeterminate cytology results cannot distinguish between follicular adenomas, follicular thyroid carcinomas or follicular variant papillary thyroid carcinomas. Accumulating evidence suggests that this limitation can be overcome by using molecular diagnostic approaches. In this Review, we present the advantages and disadvantages of the different molecular diagnostic methodologies, which can be divided into two approaches: those that 'rule out' malignancy (to reduce the overtreatment of benign nodules) and those that 'rule in' malignancy (to optimize surgical planning). We identify microRNA classifiers as potential additional markers for use in a two-step diagnostic approach, consider the potential implications of the reclassification of noninvasive encapsulated follicular variant papillary thyroid carcinomas to noninvasive follicular thyroid neoplasms with papillary-like nuclear features and discuss the cost-effectiveness of molecular testing. Molecular FNA diagnostics is an important complementary addition to FNA cytology that could substantially reduce unnecessary surgery and better define the need for appropriate surgery in patients who have thyroid nodules with indeterminate FNA cytology.
