Abstract
Context
The incidence of oropharyngeal squamous cell carcinoma has increased during the past decade and is related primarily to the human papillomavirus. This change in etiology, from tobacco and alcohol to human papillomavirus, has resulted in improved survival for the disease. In the United States, open resection had largely been replaced by concurrent chemotherapy and/or radiotherapy by the early 2000s. The advent of transoral surgery has led to an increase in surgery as the primary treatment for both early- and advanced-stage oropharyngeal squamous cell carcinoma because it has potential advantages over open surgery and nonsurgical modalities.
Objective
To provide an overview of transoral robotic surgery for oropharyngeal squamous cell carcinoma and contrast it with other surgical and nonsurgical modalities.
Data Sources
Articles from 2000 to 2014 were accessioned on PubMed and reviewed for utility by the primary authors.
Conclusions
Transoral surgery has become more commonly used as a minimally invasive approach to treat oropharyngeal tumors. Other strategies, including radiation, chemotherapy with radiation, and open surgery, are still important treatment approaches. The treatment options for an individual patient rely on multiple factors, including the tumor location and size, features of the tumor, and patient comorbidities. The continued study of these techniques is important to match the patient with the most appropriate treatment.

Abstract
OBJECTIVE The dramatic rise in oropharyngeal squamous cell carcinoma associated with the human papilloma virus (HPV) has brought significant change to the interaction between patients and head and neck oncologists. HPV-induced cancers are generally the result of elements from the patient's sexual history, and otolaryngologists are generally less experienced than primary care physicians in addressing patient questions relating to sexual history and practices. This article addresses questions commonly posed by patients relating to HPV-induced head and neck cancers, issues related to HPV vaccination, and surveillance of HPV-related lesions. Supporting data are provided such that physicians may be better equipped to sufficiently address patient queries on this topic. DATA SOURCES Available peer-reviewed literature and clinical practice guidelines. REVIEW METHODS Assessment and discussion of specific topics by authors selected from the Head and Neck Surgery Education Committee of the American Academy of Otolaryngology-Head and Neck Surgery Foundation. RESULTS An educational "miniseminar" resulted in a notable increase in attendee knowledge and comfort regarding oropharyngeal squamous cell carcinoma counseling for patients in the setting of HPV-positive disease. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE The dramatic increase in HPV-associated head and neck cancers has resulted in a changed paradigm of the physician-patient interaction. Care providers in today's environment must be prepared to counsel patients regarding sexually transmitted diseases and high-risk sexual behaviors. Examination of the existing data provides the foundation with which to construct a framework in which physicians can effectively communicate information and recommendations as they pertain to HPV-related carcinoma.

Abstract
CONTEXT Oropharyngeal squamous cell carcinoma is associated both with tobacco use and with human papillomavirus (HPV) infection. It is argued that carcinogen-driven tumorigenesis is a distinct disease from its virally driven counterpart. We hypothesized that tumorigenesis is the result of a loss of genotypic robustness resulting in an increase in phenotypic variation in tumors compared with adjacent histologically normal tissues, and that carcinogen-driven tumorigenesis results in greater variation than its virally driven counterpart. OBJECTIVES To examine the loss of robustness in carcinogen-driven and virally driven oropharyngeal squamous cell carcinoma samples, and to identify potential pathways involved. DESIGN We used coefficients of variation for messenger RNA and microRNA expression to measure the loss of robustness in oropharyngeal squamous cell carcinoma samples. Tumors were compared with matched normal tissues, and were further categorized by HPV and patient smoking status. Weighted gene coexpression networks were constructed for genes with highly variable expression among the HPV⁻ tumors from smokers. RESULTS We observed more genes with variable messenger RNA expression in tumors compared with normal tissues, regardless of HPV and smoking status, and more microRNAs with variable expression in HPV⁻ and HPV⁺ tumors from smoking patients than from nonsmokers. For both the messenger RNA and microRNA data, we observed more variance among HPV⁻ tumors from smokers compared with HPV⁺ tumors from nonsmokers. The gene coexpression network construction highlighted pathways that have lost robustness in carcinogen-induced tumors but appear stable in virally induced tumors. CONCLUSIONS Using coefficients of variation and coexpression networks, we identified multiple altered pathways that may play a role in carcinogen-driven tumorigenesis.

Abstract
We evaluated the risk factors associated with oral human papillomavirus (HPV) infection and oral lesions in 161 human immunodeficiency virus (HIV)-positive patients and 128 HIV-negative patients presenting for oral examination at 2 urban healthcare centers. Patients were interviewed on risk factors and provided oral-rinse samples for HPV DNA typing by polymerase chain reaction. Statistical associations were assessed by logistic regression. Oral HPV was prevalent in 32% and 16% of HIV-positive patients and HIV-negative patients, respectively, including high-risk HPV type 16 (8% and 2%, respectively; P = .049) and uncommon HPV types 32/42 (6% and 5%, respectively; P = .715). Among HIV-negative patients, significant risk factors for oral HPV included multiple sex partners (≥21 vs ≤5; odds ratio [OR], 9.1; 95% confidence interval [CI], 1.7-49.3), heavy tobacco smoking (>20 pack-years vs none; OR, 9.2; 95% CI, 1.4-59.4), and marijuana use (OR, 4.0; 95% CI, 1.3-12.4). Among HIV-positive patients, lower CD4(+) T-cell count only was associated with oral HPV detection (≤200 vs ≥500 cells/mm(3); OR, 4.5; 95% CI, 1.3-15.5). Detection of high-risk HPV was also associated with concurrent detection of potentially cancerous oral lesions among HIV-negative patients but not among HIV-positive patients. The observed risk factor associations with oral HPV in HIV-negative patients are consistent with sexual transmission and local immunity, whereas in HIV-positive patients, oral HPV detection is strongly associated with low CD4(+) T-cell counts.

Abstract
Human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is recognized as a distinct disease entity associated with improved survival. DNA hypermethylation profiles differ significantly by HPV status suggesting that a specific subset of methylated CpG loci could give mechanistic insight into HPV-driven OPSCC. We analyzed genome-wide DNA methylation of primary tumor samples and adjacent normal mucosa from 46 OPSCC patients undergoing treatment at Montefiore Medical Center, Bronx, NY using the Illumina HumanMethylation27 beadchip. For each matched tissue set, we measured differentially methylated CpG loci using a change in methylation level (M value). From these analyses, we identified a 22 CpG loci panel for HPV+ OPSCC that included four CDKN2A loci downstream of the p16(INK4A) and p14(ARF) transcription start sites. This panel was significantly associated with overall HPV detection (P < 0.05; ROC area under the curve = 0.96, 95% CI: 0.91-1.0) similar to the subset of four CDKN2A-specific CpG loci (0.90, 95% CI: 0.82-0.99) with equivalence to the full 22 CpG panel. DNA hypermethylation correlated with a significant increase in alternative open reading frame (ARF) expression in HPV+ OPSCC primary tumors, but not to the other transcript variant encoded by the CDKN2A locus. Overall, this study provides evidence of epigenetic changes to the downstream region of the CDKN2A locus in HPV+ oropharyngeal cancer that are associated with changes in expression of the coded protein products.

Abstract
CONTEXT Global proteomic analysis of oral cavity squamous cell carcinoma was performed to identify changes that reflect patient outcomes. OBJECTIVES To identify differentially expressed proteins associated with patient outcomes and to explore the use of imaging mass spectrometry as a clinical tool to identify clinically relevant proteins. DESIGN Two-dimensional separation of digested peptides generated from 43 specimens with high-resolution mass spectrometry identified proteins associated with disease-specific death, distant metastasis, and loco-regional recurrence. RNA expressions had been correlated to protein levels to test transcriptional regulation of clinically relevant proteins. Imaging mass spectrometry explored an alternative platform for assessing clinically relevant proteins that would complement surgical pathologic diagnosis. RESULTS Seventy-two peptide features were found to be associated with 3 patient outcomes: disease-specific death (9), distant metastasis (16), and loco-regional recurrence (39); 8 of them were associated with multiple outcomes. Functional ontology revealed major changes in cell adhesion and calcium binding. Thirteen RNAs showed strong correlation with their encoded proteins, implying transcriptional control. Reduction of DSP, PKP1, and TRIM29 was associated with significantly shorter time to onset of distant metastasis. Reduction of PKP1 and TRIM29 correlated with poorer disease-specific survival. Additionally, S100A8 and S100A9 reductions were verified for their association with poor prognosis using imaging mass spectrometry, a platform more adaptable for use with surgical pathology. CONCLUSIONS Using global proteomic analysis, we have identified proteins associated with clinical outcomes. The list of clinically relevant proteins observed will provide a means to develop clinical assays for prognosis and optimizing treatment selection.

Abstract
Program Description: Human papillomavirus (HPV)–related oropharyngeal cancer is now recognized as a clinically distinct entity, and data describing the nature of the epidemic, optimal treatment strategies, and survival outcomes are rapidly developing. Our patients are asking pertinent questions about HPV transmission, the role of vaccination, and monitoring recommendations. This miniseminar will update practitioners on the accuracy of testing, how to counsel patients and families regarding the nature of HPV infection (risk and transmissibility), vaccination, the management of benign lesions, and surveillance. This panel will appeal broadly to trainees, general otolaryngologists, and head and neck surgical oncologists. Educational Objectives: (1) Advise patients and partners regarding HPV infection and transmission. (2) List the Centers for Disease Control and Prevention recommendations for HPV vaccination. (3) Develop a surveillance plan for patients with HPV and their families.

Abstract
BACKGROUND Eagle syndrome is often considered in the work-up of odynophagia and neck pain. Classically, this is manifested by ossification or calcification of the stylohyoid ligament or styloid process. There are no reported cases of stylopharyngeal calcification leading to these symptoms. CASE We describe a patient with a suspected submucosal pharyngeal foreign body who was found to have a calcified stylopharyngeus muscle and tendon during surgery. The patient experienced full resolution of symptoms after transoral robotic resection. This diagnosis was initially missed because the radiology was inconsistent with Eagle syndrome. CONCLUSION This is the first report of isolated stylopharyngeal calcification, and this unique manifestation of a stylohyoid complex syndrome should be considered in patients with symptoms of Eagle syndrome without styloid elongation.

Abstract
OBJECTIVES/HYPOTHESIS To evaluate the etiology and risk factors for severe manifestation and recurrent episodes of angioedema; to evaluate efficacy of short-term and long-term management strategies for angioedema among a high-risk population. STUDY DESIGN Institutional review board-approved retrospective review of a large, urban population. METHODS Data from 875 adult patients treated from January 2008 to December 2013 with the diagnosis of angioedema were obtained using the Clinical Looking Glass utility and review of medical records. Demographic and clinicopathologic risk factors were recorded. The major outcomes evaluated were hospital admission, need for airway intervention, and recurrent episodes of angioedema following the first presentation. Initial treatment strategy and follow-up recommendations were also recorded. RESULTS The most common cause of angioedema was angiotensin converting enzyme inhibitor (ACEi)-induced (496 [56.6%]). Significant risk factors for severe cases of angioedema included older age, Hispanic race, ACEi-induced angioedema type, American Society of Anesthesiologists class III or above, coexistent cardiopulmonary disease, and a positive smoking history. A total of 17.2% of patients experienced recurrent attacks of angioedema; of those patients, 25.9% were still taking an ACEi at subsequent presentation. Risk factors for recurrent episodes included older age, idiopathic angioedema type, and coexistent cardiopulmonary disease. Only 54.1% of patients who experienced ACEi-induced angioedema had electronic medical record documentation of these allergies. CONCLUSIONS Knowledge of risk factors for severe and recurrent episodes of angioedema and improved education for both healthcare providers and patients, specifically related to ACEi use and allergy documentation, may significantly decrease the burden and morbidity of angioedema among high risk populations. LEVEL OF EVIDENCE 2b.

Abstract
While its prognostic significance remains unclear, p16(INK4a) protein expression is increasingly being used as a surrogate marker for oncogenic human papillomavirus (HPV) infection in head and neck squamous cell carcinomas (HNSCC). To evaluate the prognostic utility of p16 expression in HNSCC, we prospectively collected 163 primary tumor specimens from histologically confirmed HNSCC patients who were followed for up to 9.4 years. Formalin fixed tumor specimens were tested for p16 protein expression by immunohistochemistry (IHC). HPV type-16 DNA and RNA was detected by MY09/11-PCR and E6/E7 RT-PCR on matched frozen tissue, respectively. P16 protein expression was detected more often in oropharyngeal tumors (53%) as compared with laryngeal (24%), hypopharyngeal (8%) or oral cavity tumors (4%; p<0.0001). With respect to prognosis, p16-positive oropharyngeal tumors exhibited significantly better overall survival than p16-negative tumors (log-rank test p=0.04), whereas no survival benefit was observed for nonoropharyngeal tumors. However, when both p16 and HPV DNA test results were considered, concordantly positive nonoropharyngeal tumors had significantly better disease-specific survival than concordantly negative nonoropharyngeal tumors after controlling for sex, nodal stage, tumor size, tumor subsite, primary tumor site number, smoking and drinking [adjusted hazard ratio (HR)=0.04, 0.01-0.54]. Compared with concordantly negative nonoropharyngeal HNSCC, p16(+)/HPV16(-) nonoropharyngeal HNSCC (n=13, 7%) demonstrated no significant improvement in disease-specific survival when HPV16 was detected by RNA (adjusted HR=0.83, 0.22-3.17). Our findings show that p16 IHC alone has potential as a prognostic test for oropharyngeal cancer survival, but combined p16/HPV testing is necessary to identify HPV-associated nonoropharyngeal HNSCC with better prognosis.

Abstract
Objective: The objective was to determine patient and gland characteristics associated with difficult intubation in patients undergoing thyroidectomy for goiter and to assess different methods of intubation in these patients. Methods: This study was an IRB-approved, retrospective chart review of 112 consecutive patients undergoing hemithyroidectomy or total thyroidectomy for thyroid goiter from 2009-2012 at an academic tertiary care facility in Bronx, New York. Patient demographics, thyroid gland characteristics (gland weight and nodule size), presence of preoperative symptoms (dyspnea, dysphagia, and hoarseness), and radiographical findings (tracheal compression, tracheal deviation, and substernal extension of the thyroid gland) were recorded. Anesthesia records were reviewed for method of intubation, as well as success or failure of intubation attempts. Results: Nineteen patients (17.0%) were men and 93 (83.0%) were women. The age of the patients included in the study ranged from 14 to 86 years with a mean ± SD age of 53.5 ± 14.7 years. Difficult intubation was noted with 13 (11.6%) patients. Only patient age was significantly associated with difficult intubation. The mean age of patients with airway difficulty was 60.7 ± 3.7 years compared to 52.1 ± 1.5 years in those who did not experience airway difficulty ( P = .04). No other reviewed risk factors were found to be significantly associated with difficult intubation. Fiberoptic intubation (FOI) was used in 38 patients and difficult intubation occurred in 18.4% (7/38). Direct laryngoscopy with transoral intubation (LTOI) was used in 58 patients, in whom 3.4% (2/58) experienced a difficult intubation. FOI was aborted 6 times and LTOI was subsequently successful in each of these cases. Conclusions: Our results suggest that benign nodular goiter disease does not pose significant challenges to intubation in our patient cohort. The technique of intubation deviated from the initial plan several times in the FOI group, whereas LTOI was ultimately successful in every case. Our data suggest that the role of fiberoptic intubation for patients with large goiters should be further refined.

Abstract
Program Description: As the demographics of oropharyngeal cancer change, so too will its management. Since these patients are often younger, have a better prognosis, and have presumably a longer life expectancy, we will discuss variations in treatment regimens. Using a case-based format and presentations from experts in the field, this miniseminar will review the management of the HPV-related cancer patient: molecular markers, chemotherapy and radiotherapy, the expanding role of surgery, neck management, and the potential for de-escalation of therapy. We will provide the practitioner with a practical, useful, and evidence based approach to the treatment of the HPV positive cancer patient. Educational Objectives: 1) Recognize biomarkers for HPV-related head and neck cancer and understand their utility and limitations in clinical practice. 2) Develop a rational treatment plan for HPV-related head and neck cancer patients.

Abstract
PURPOSE We have used a genome-wide approach to identify novel differentially methylated CpG dinucleotides that are seen in different anatomic sites of head and neck squamous cell carcinoma (HNSCC), as well as those that might be related to HPV status in the oropharynx. EXPERIMENTAL DESIGN We conducted genome-wide DNA methylation profiling of primary tumor samples and corresponding adjacent mucosa from 118 HNSCC patients undergoing treatment at Montefiore Medical Center, Bronx, NY, using the Illumina HumanMethylation27 beadchip. For each matched tissue set, we measured differentially methylated CpG loci using a change in methylation level (M-value). RESULTS When datasets were individually analyzed by anatomic site of the primary tumor, we identified 293 differentially methylated CpG loci in oral cavity squamous cell carcinoma (SCC), 219 differentially methylated CpG loci in laryngeal SCC, and 460 differentially methylated in oropharyngeal SCC. A subset of these differentially methylated CpG loci was common across all anatomic sites of HNSCC. Stratification by HPV status revealed a significantly higher number of differentially methylated CpG loci in HPV+ patients. CONCLUSION Novel epigenetic biomarkers derived from clinical HNSCC specimens can be used as molecular classifiers of this disease, revealing many new avenues of investigation for this disease.

OBJECTIVE To demonstrate the importance of comorbid conditions in head and neck squamous cell carcinoma (HNSCC), we assessed the association between comorbidity and survival in an inner-city population of HNSCC patients. PATIENTS AND METHODS Comorbid status at diagnosis was derived using medical records and the Adult Comorbidity Evaluation-27 (ACE-27) index on 288 patients with histologically confirmed HNSCC from Montefiore Medical Center in the Bronx (NY) between 2002 and 2011. The association between comorbidity, tumor human papillomavirus (HPV) status and overall and disease specific survival was assessed by Kaplan-Meier analysis and multivariable Cox regression adjusting for clinico-pathologic factors. RESULTS The study population consisted of primary oropharyngeal (36%), laryngeal (33%) and oral cavity cancer patients (31%). Overall, 19% had no comorbidity, 43% mild comorbidity, 29% moderate comorbidity, and 9% severe comorbidity. The most common comorbid conditions were hypertension, diabetes mellitus, respiratory disease, other malignancies, and illicit drug use. Survival analyses revealed that increased comorbidity at diagnosis was significantly related to poorer overall survival (p=0.016), but not to cancer survival (p=0.369) or recurrence (p=0.652). Oropharyngeal cancer patients with HPV DNA positive tumors and lower levels of comorbidity had significantly better overall survival compared to patients with HPV negative tumors (hazard ratio=0.2, 95%CI: 0.04-0.8), however there was no significant difference in overall (or disease specific) survival by HPV status among patients with higher levels of comorbidity at diagnosis (hazard ratio=0.7, 95%CI: 0.2-2.8). CONCLUSION In an inner-city predominantly minority population, comorbidity at HNSCC diagnosis is relatively common and associated with poor overall survival, but not cancer survival or recurrence. Interestingly, the relationship between HPV and improved survival appears to be specific to patients with low comorbidity at diagnosis.

Abstract
OBJECTIVES/HYPOTHESIS Minimally invasive surgery has become the standard of care in many organ systems. Head and neck surgery has incorporated transoral surgery, either laser microsurgery or robotic resection, in the management of pharyngeal and laryngeal cancers. To date, the laryngeal procedures have taken the form of partial laryngectomy, as transoral approaches have not allowed reconstruction following total laryngectomy. We present the first series of transoral total laryngectomies. STUDY DESIGN Multinational, multi-institutional prospective consecutive case series. METHODS Case series of completed and attempted transoral robotic surgery (TORS) total laryngectomy performed under an institutional review board protocol. The procedure was developed in the cadaver laboratory and applied to selected individuals requiring total laryngectomy for recurrent laryngeal cancer or post-therapeutic organ dysfunction. RESULTS TORS total laryngectomy was successfully performed in five patients and was unsuccessful in two others. Two of the patients had postoperative fistulae, and all seven are without evidence of recurrent cancer and are swallowing orally without gastrostomy supplementation. CONCLUSIONS TORS total laryngectomy is feasible and can be taught to other surgeons. Potential benefits of this approach are present for patients undergoing salvage laryngectomy and include improved wound healing and functional results. This procedure further extends the applications of robotic head and neck surgery.

Validation of the risk model: high-risk classification and tumor pattern of invasion predict outcome for patients with low-stage oral cavity squamous cell carcinoma. Head Neck Pathol 2012; 7:211-23. [PMID: 23250819 PMCID: PMC3738758 DOI: 10.1007/s12105-012-0412-1] [Citation(s) in RCA: 118] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2012] [Accepted: 11/30/2012] [Indexed: 11/28/2022]
Abstract
The risk model is a validated outcome predictor for patients with head and neck squamous cell carcinoma (Brandwein-Gensler et al. in Am j surg pathol 20:167-178, 2005; Am J Surg Pathol 34:676-688, 2010). This model may potentially shift treatment paradigms for patients with low-stage cancers, as current protocols dictate that they might receive only primary surgery. Here we test the hypothesis that the Risk Model has added prognostic value for low-stage oral cavity squamous cell carcinoma (OCSCC) patients. 299 patients with Stage I/II OCSCC were characterized according to the risk model (Brandwein-Gensler et al. in Am J Surg Pathol 20:167-178, 2005; Am J Surg Pathol 34:676-688, 2010). Cumulative incidence and competing risk analysis were performed for locoregional recurrence (LRR) and disease-specific survival (DSS). Receiver operating characteristic analyses were performed for worst pattern of invasion (WPOI) and the risk categories. 292 patients were analyzed; 30 T1N0 patients (17%) and 26 T2N0 patients (23%) developed LRR. Disease-specific mortality occurred in 9 T1N0 patients (6%) and 9 T2N0 patients (10%). On multivariable analysis, the risk model was significantly predictive of LRR (p = 0.0012, HR 2.41, 95% CI 1.42, 4.11) and DSS (p = 0.0005, HR 9.16, 95% CI 2.65, 31.66) adjusted for potential confounders. WPOI alone was also significantly predictive for LRR adjusted for potential confounders with a cut-point of either WPOI-4 (p = 0.0029, HR 3.63, 95% CI 1.56, 8.47) or WPOI-5 (p = 0.0008, HR 2.55, 95% CI 1.48, 4.41) and for DSS (cut point WPOI-5, p = 0.0001, HR 6.34, 95% CI 2.50, 16.09). Given a WPOI-5, the probability of developing locoregional recurrence is 42%. Given a high-risk classification for a combination of features other than WPOI-5, the probability of developing locoregional recurrence is 32%. The Risk Model is the first validated model that is significantly predictive for the important niche group of low-stage OCSCC patients.

Abstract
Mucoepidermoid carcinoma (MEC) is a relatively common salivary tumor with varying potential for aggressive behavior. Mucoepidermoid carcinoma grading has evolved from descriptive two-tiered schemata to more objective three-tiered systems. In 2001, we published a grading system Brandwein et al. in Am J Surg Pathol 25:835-845, (2001) which modified the prevailing criteria of Auclair et al. in Cancer 69:2021-2030 (1992), and included additional features of aggressive MEC. Here we seek to validate our modified grading system in a new multicenter cohort. The retrospective cohort consisted of 76 patients with confirmed MEC and known outcome data. The resection specimens were reviewed and uniformly graded according to our modified criteria Brandwein et al. in Am J Surg Pathol 25:835-845 (2001), and the Auclair criteria Auclair et al. in Cancer 69:2021-2030, (1992), Goode et al. in Cancer 82:1217-1224, (1998). Case distribution was as follows: Montefiore Medical Center: 41 (1977-2009), University of Alabama at Birmingham: 21 (1999-2010), and Rhode Island Hospital: 14, (1995-2011). Patient age ranged from 7 to 81 years (mean 51 years). The female to male ratio was 3:1. The most commonly involved sites were: parotid: n = 39 (51%), palate: n = 10 (13%), retromolar trigone: n = 6 (8%), buccal: n = 5 (7%), and submandibular gland: n = 5 (7%). The modified criteria upgraded 41% MEC; 20/25 MEC from AFIP Grade 1 to Grade 2 and 5/25 from AFIP grade 1 to grade 3. Eleven patients had positive lymph nodes; the AFIP MEC grade for cases were: grade 1-3/11, Grade 2-1/11, and grade 3-7/11; the modified grading criteria distribution for these cases were Grade 1: 0/11, grade 2: 1/11, and grade 3: 10/11. Nine patients developed disease progression after definitive treatment. High-stage and positive lymph node status were significantly associated with disease progression (p = 0.0003 and p < 0.0001, respectively). For the nine patients with disease progression, the modified grading schema classified eight MEC as grade 3 and one as grade 2. By comparison, the AFIP grading schema classified three of these MEC as grade 1, and the remaining six as grade 3. Despite the fact that this multicenter retrospective study accrued 76 patients with outcome, the predictive performance of the two grading schema could not be compared due to the few patients who experienced disease progression and were also reclassified with respect to grade (n = 3).
