RESUMEN

OBJECTIVES: Determine if intensive local therapy (i.e., local surgery or radiation) has a survival benefit for patients presenting with distantly metastatic oropharyngeal squamous cell carcinoma (OPSCC). METHODS: Retrospective population-based cohort study of patients in the National Cancer Database presenting with distantly metastatic OPSCC. Overall survival (OS) was compared for patients receiving systemic therapy alone or in combination with local surgery or curative dose radiation, controlling for various clinicodemographic factors. RESULTS: Between 2010 and 2015, 627 patients presented with newly diagnosed, metastatic OPSCC and an initial treatment course including systemic chemotherapy. Multivariable analysis demonstrated that local radiation therapy was independently associated with improved OS (OR 0.64, CI [0.51-0.81]); local surgery was not independently associated with improved OS (OR 0.99, CI [0.65-1.53]). Higher T stages were associated with worse OS (OR 1.69, CI [1.14-2.50] for T3 and OR 1.77, CI [1.22-2.58] for T4 compared to T1). HPV-positive (HPV+) tumors were associated with improved OS compared to HPV- (OR 0.79, CI [0.64-0.97]). Multiagent chemotherapy was associated with improved OS compared to single-agent (OR 0.78, CI [0.62-1.00]). The best survival for the entire cohort and for HPV+ patients was for radiation with systemic therapy and the worst survival for systemic therapy alone. CONCLUSIONS: Curative dose local radiotherapy in addition to systemic therapy is associated with improved OS compared to systemic therapy alone in patients presenting with distantly metastatic OPSCC. There is not a significant survival benefit for local surgery in addition to systemic therapy in this patient population, regardless of HPV status.

RESUMEN

Emerging evidence suggests that not only the frequency and composition of tumor-infiltrating leukocytes but also their spatial organization might be a major determinant of tumor progression and response to therapy. Therefore, mapping and analyzing the fine tumor immune architecture could potentially provide insights for predicting cancer prognosis. Here, we performed an explorative, prospective clinical study to assess whether structures within the tumor microenvironment can predict recurrence after salvage surgery in head and neck squamous cell carcinoma (HNSCC). The major immune subsets were measured using flow cytometry and co-detection by indexing (CODEX) multiparametric imaging. Flow cytometry underestimated the number of PMN-MDSCs and neutrophils in the tumor and overestimated the tumor-infiltrating lymphocyte frequency. An ad hoc computational framework was used to identify and analyze discrete cellular neighborhoods. A high frequency of tertiary lymphoid structures composed of CD31highCD38high plasma cells was associated with reduced recurrence after surgery in HNSCC. These data support the notion that the structural architecture of the tumor immune microenvironment plays an essential role in tumor progression and indicates that type 1 tertiary lymphoid structures and long-lived CD31highCD38high plasma cells are associated with good prognosis in HNSCC. SIGNIFICANCE: Imaging the spatial tumor immune microenvironment and evaluating the presence of type 1 tertiary lymphoid structures enables prediction of recurrence after surgery in patients with head and neck squamous cell carcinoma.

RESUMEN

BACKGROUND: The radial forearm free flap (RFFF) is considered a workhorse for head and neck cancer reconstructive surgery due to its generally consistent anatomy, pliability, long pedicle, and accessible harvest location. METHODS: A 63-year-old male with trisomy 21 and recurrent midface basal cell carcinoma presented for surgical management. The patient underwent tumor resection including left infrastructure maxillectomy with ipsilateral rhinectomy. Preoperative Allen's test was normal; however, the planned osteocutaneous radial forearm free flap reconstruction was aborted intraoperatively due to aberrant vascular anatomy in the form of a diminutive radial artery branch. Reconstruction was instead performed with an anterolateral thigh free flap. RESULTS: The patient recovered well in the hospital and was subsequently discharged to his care facility. CONCLUSIONS: Radial artery anomalies may be present among trisomy 21 patients making reconstruction with a RFFF not feasible, and thus preoperative Doppler ultrasound to assess arterial anatomy is essential in this population.

RESUMEN

Salivary gland neoplasms are uncommon, and most exhibit epithelial differentiation. Mesenchymal neoplasms of the salivary gland are rare, and the incidence ranges from 1.9% to 5%. The aim of this study is to identify the types and clinical-pathological features of mesenchymal salivary neoplasm and review their differential diagnosis. A retrospective search for mesenchymal neoplasms of salivary glands from our institution's pathology archives from the 2004-2021 period and consultation files of one of the authors (AER) was performed. The clinical data were obtained from available medical records, and the histological slides and ancillary studies were retrieved and reviewed. We identified a total of 68 cases that form the study cohort. Thirty-five patients were male, and thirty-three patients were female, with a mean age of 48 years (range, 7 months-79 years), and the male to female ratio was 1:.94. Sixty-three (92.6%) of sixty-eight tumors were benign and included: 38 (56%) lipomas, 9 (13%) hemangiomas, 7 (10.3%) schwannomas, 3 (4.4%) neurofibromas, 3 (4.4%) lymphangioma, 2 (3%) solitary fibrous tumors, 1 (1.5%) myofibroma. Five of sixty-eight (7.4%) were malignant and included: 3 (4.4%) Adamantinoma-like Ewing sarcomas, 1 (1.5%) malignant peripheral nerve sheath tumor (MPNST), and 1 (1.5%) malignant solitary fibrous tumor. The involved sites included: parotid (55), submandibular gland (5), parapharyngeal space (5), buccal mucosa minor salivary gland (2), and sublingual gland (1). Sixty-seven patients underwent surgical resection. One patient with lymphangioma manifested a recurrence/persistence a week post-surgery. One patient with a parotid hemangioma developed post-operative numbness, and another patient developed chronic postauricular pain after surgery. Two patients with MPNST and one patient with adamantinoma-like Ewing sarcoma underwent neoadjuvant chemoradiation and were disease-free after treatment. The remaining 37 patients with available follow-up ranging from 7 days to 96 months (mean, 18 months) had a favorable outcome and were disease-free after treatment. Mesenchymal neoplasms of salivary gland are rare; most are benign and demonstrate adipocytic, endothelial, and schwannian differentiation; awareness of their development is important for adequate diagnosis. The mainstay of treatment is surgical excision, with the extent determined by tumor type. Adjuvant therapy is reserved for high-grade sarcomas and may be given in a neoadjuvant or adjuvant setting.

RESUMEN

Primary sarcomas of the larynx are rare and are associated with diagnostic and treatment challenges. Studies of these tumors are limited, and most examples have been reported as small series. To further increase our understanding of laryngeal sarcomas, we reviewed our experience of an adult cohort. A retrospective search for laryngeal sarcomas from our pathology archives and consultation files of one of the authors was performed. We studied 27 primary laryngeal sarcomas that included 25 males, and 2 females, with a mean age of 60 years (range 33-85). The cases included conventional chondrosarcoma (16), well-differentiated liposarcoma (2), clear cell chondrosarcoma (1), leiomyosarcoma (2), high grade myxofibrosarcoma (2), high grade myofibroblastic sarcoma (1), low-grade myofibroblastic sarcoma (1), malignant granular cell tumor (1), and Kaposi sarcoma (1). Data on treatment and follow-up was available in 17 and 16 cases, respectively. 12 patients underwent partial laryngeal resection; five had total laryngectomy, and the patient with Kaposi sarcoma received combined highly active antiretroviral therapy and chemotherapy. Three patients developed local recurrence, and two patients developed metastases. The remaining patients with follow up had a favorable outcome and were disease-free after treatment. The important differential diagnosis of spindle cell sarcoma is sarcomatoid squamous cell carcinoma, and their distinction often requires extensive sampling of the mucosal surface and immunohistochemical analysis. The mainstay of treatment for laryngeal sarcomas is surgical removal, with the extent dictated by tumor type and grade. Adjuvant therapy is reserved for high-grade sarcomas and may be given in a neoadjuvant or adjuvant setting.

RESUMEN

OBJECTIVES: The behavior of advanced cutaneous squamous cell carcinoma of the head and neck (HNcSCC) remains poorly understood, with highly variable risk factors and a paucity of data for adjuvant treatment. The objective of our study was to review the oncologic outcomes of patients with high-risk HNcSCC treated with surgery and to identify risk factors for treatment failure. STUDY DESIGN: Retrospective cohort study. METHODS: Retrospective review of patients treated for HNcSCC with definitive surgery involving at least parotidectomy and neck dissection at a tertiary care academic center from 2011 to 2017 was conducted. The primary outcome was disease-free survival (DFS). RESULTS: One-hundred four patients with a median age of 68 years (range = 42-91 years) were reviewed. Twenty-one patients were treated with surgery alone, 45 patients underwent adjuvant radiotherapy (RT), and 38 patients underwent adjuvant chemoradiotherapy (CRT). The 2-year DFS for patients treated with surgery, surgery + RT, and surgery + CRT were 71%, 65%, and 58%, respectively, with no significant difference between the groups (P = .70). On multivariate analyses, tumor size (P = .006) and perineural invasion (PNI, P = .04) independently predicted recurrence. The addition of chemotherapy did not appear to improve DFS, neither for those patients with extranodal extension and/or positive margins (P = .93) nor for the entire cohort (P = .43). CONCLUSIONS: Advanced HNcSCC has a high recurrence rate despite adjuvant treatment. Tumor size >2 cm was a strong independent risk factor for recurrence. Out of the traditional mucosal HNcSCC risk factors, PNI was most strongly associated with worse DFS. There was no observed survival benefit to the addition of chemotherapy. LEVEL OF EVIDENCE: 4.

RESUMEN

Granular cell tumors (GCT) are rare soft tissue tumors that involve the head and neck in 50% of patients. Two distinct variants of GCT, one benign (bGCT) and the other malignant (mGCT), involving the hypopharynx, a subsite of the larynx, are presented here. The clinical presentations, radiographic features, pathologic diagnosis in these two variants of GCT are discussed. The mGCT was diagnosed only after complete tumor excision. This report highlights the importance of complete excision of the tumor mass, as diagnosis of mGCT can be exceedingly difficult to make on a small biopsy specimen. Therefore, complete excision is recommended for definitive diagnosis and treatment of GCTs.

RESUMEN

OBJECTIVE: There has been a significant shift from open craniofacial resection of the anterior skull base to endoscopic approaches that accomplish the same outcomes in tumor ablation. However, when open resection is required, free flap reconstruction is often necessary to provide sufficient well-vascularized tissue for optimal wound healing as well as providing adequate tissue bulk for cosmesis. This articleaims to providea focused review of free flaps most commonly used in anterior skull base reconstruction. METHODS: This is a state-of-the-art review based on expert opinion and previously published reviews and journal articles, queried using PubMed and Google Scholar. RESULTS & CONCLUSION: Anterior skull base reconstruction via free tissue transfer is imperative in limiting complications and promoting healing, particularly with large defects, post-radiation, and in at-risk patients. The type of free flap utilized for a particular anterior skull base reconstruction should be tailored to the patient and nature of the disease. This review offers insight into the numerous reconstructive options for the free flap surgeon.

RESUMEN

BACKGROUND: No reports describe falsepositive reverse transcriptase polymerase chain reaction (RT-PCR) for novel coronavirus in preoperative screening. METHODS: Preoperative patients had one or two nasopharyngeal swabs, depending on low or high risk of viral transmission. Positive tests were repeated. RESULTS: Forty-three of 52 patients required two or more preoperative tests. Four (9.3%) had discrepant results (positive/negative). One of these left the coronavirus disease (COVID) unit against medical advice despite an orbital abscess, with unknown true disease status. The remaining 3 of 42 (7.1%) had negative repeat RT-PCR. Although ultimately considered falsepositives, one was sent to a COVID unit postoperatively and two had urgent surgery delayed. Assuming negative repeat RT-PCR, clear chest imaging, and lack of subsequent symptoms represent the "gold standard," RT-PCR specificity was 0.97. CONCLUSIONS: If false positives are suspected, we recommend computed tomography (CT) of the chest and repeat RT-PCR. Validated serum immunoglobulin testing may ultimately prove useful.

RESUMEN

BACKGROUND: Coronavirus has serially overtaken our metropolitan hospitals. At peak, patients with acute respiratory distress syndrome may outnumber mechanical ventilators. In our Miami Hospital System, COVID-19 cases have multiplied for 4 weeks and elective surgery has been suspended. METHODS: An Otolaryngologic Triage Committee was created to appropriately allocate resources to patients. Hospital ethicists provided support. Our tumor conference screened patients for nonsurgical options. Patients were tested twice for coronavirus before performing urgent contaminated operations. N95 masks and protective equipment were conserved when possible. Patients with low-grade cancers were advised to delay surgery, and other difficult decisions were made. RESULTS: Hundreds of surgeries were canceled. Sixty-five cases screened over 3 weeks are tabulated. Physicians and patients expressed discomfort regarding perceived deviations from standards, but risk of COVID-19 exposure tempered these discussions. CONCLUSIONS: We describe the use of actively managed surgical triage to fairly balance our patient's health with public health concerns.

RESUMEN

Human papillomavirus (HPV) in oropharyngeal squamous cell carcinoma (SCC) is a well-known cause and prognostic indicator, and the utility of p16 as a surrogate marker for HPV status has been established. P16 and its relationship with HPV have not been defined in sinonasal malignancy nor has a link with outcomes been established. Patients with sinonasal SCC from 2011 to 2017 were identified from our pathology database. P16 immunohistochemistry and HPV RNA in situ hybridization were performed on tissue specimens. Forty-seven patients were included. Disease-free survival for p16+ patients was significantly higher than p16- patients (P = .043). Fewer HPV+ patients died (P = .052) or experienced recurrence (P = .0437). Odds ratio between p16 and HPV status was 14.19 (95% CI: 1.72, 442.03). Our findings demonstrate improved survival in both the p16+ and HPV+ groups and a positive association between p16 and HPV. There may be similar potential for modifying classification for HPV+ sinonasal SCC.

RESUMEN

BACKGROUND: Microvascular free tissue transfer provides superior functional outcomes when reconstructing head and neck cancer defects. Careful patient selection and surgical planning is necessary to ensure success, as many preoperative, intraoperative, and postoperative patient and technical factors may affect outcome. AIMS: To provide a concise, yet thorough, review of the current literature regarding free flap patient selection and management for the patient with head and neck. MATERIALS AND METHODS: PubMed and Cochrane databases were queried for publications pertaining to free tissue transfer management and outcomes. RESULTS: Malnutrition and tobacco use are modifiable patient factors that negatively impact surgical outcomes. The use of postoperative antiplatelet medications and perioperative antibiotics for greater than 24 hours have not been shown to improve outcomes, although the use of clindamycin alone has been shown to have a higher risk of flap failure. Liberal blood transfusion should be avoided due to higher risk of wound infection and medical complications. DISCUSSION: There is a wide range of beliefs regarding proper management of patients undergoing free tissue transfer. While there is some data to support these practices, much of the data is conflicting and common practices are often continued out of habit or dogma. CONCLUSION: Free flap reconstruction remains a highly successful surgery overall despite as many different approaches to patient care as there are free flap surgeons. Close patient monitoring remains a cornerstone of surgical success.

RESUMEN

BACKGROUND: The presence of two or more tumor entities growing in adjacent locations within the salivary gland is very rare, and pathologic studies on such lesions are limited, particularly those with molecular information. Since the clinical history and imaging studies are usually nonspecific, accurate diagnosis and clinical management largely depend on a thorough histological examination. METHODS AND RESULTS: We describe a 71-year-old man with an unusual case of hybrid salivary gland tumor composed of mucoepidermoid carcinoma and basal cell adenoma. Molecular analysis revealed differing driver genetic alterations in each component. CONCLUSIONS: Hybrid salivary gland tumors are rare, and their pathogenesis is controversial. The combination of mucoepidermoid carcinoma and basal cell adenoma has not been previously described. While malignant transformation of adenoma to carcinoma seems plausible, gene sequencing was more suggestive of their independent derivation. Key to appropriate surgical management is identifying the more aggressive component, ideally at the time of intraoperative consultation.

RESUMEN

BACKGROUND: Optimal transoral surgical modality for oropharyneal carcinoma is currently unclear. Transoral laser surgery (TLS), transoral robotic surgery (TORS), and conventional direct transoral (DT) oropharyngectomy are the main current transoral surgical modalities for oropharyngeal carcinoma. METHODS: MEDLINE was systematically searched through PubMed. Reference lists were reviewed. Random-effects models were used to combine studies within each group. Tests for heterogeneity were used to explore difference in effect size between groups in subgroup analysis. RESULTS: Nine studies (404 patients) in TORS arm, five studies (498 patients) in TLS arm, and three studies (335 patients) in DT arm were included. Early T classification (T1-T2) for TORS and DT were higher compared to TLS group (P < .001). There was no significant difference between groups in the rate of invaded margin, post-operative oropharyngeal bleeding, temporary tracheotomy, and gastrostomy dependence. CONCLUSION: The available data do not yet provide clear evidence of superiority of any one modality.

RESUMEN

Pharyngocutaneous fistula after laryngectomy is common and significantly increases the morbidity of the procedure. Intraoperative, objective variables that can reliably predict fistula formation would be useful to surgeons deciding how to reconstruct the laryngectomy defect. Retrospective chart review of 50 radiated patients and 10 non-radiated patients who underwent total laryngectomy at a single tertiary care institution. Patients with pharyngocutaneous fistula were selected to ensure a representative sample were available for comparison. All patients had pathology slides available for re-review by a single, blinded pathologist. Margins of both radiated (n = 50) and non-radiated (n = 10) larynges were examined for 7 histologic features, and odds ratios were calculated to assess whether these features were associated with fistula. When evaluating all 60 patients, both telangiectatic capillaries and hyalinized arterioles were associated with fistula (OR 3.72 and 9.21, respectively). Collinearity between the variables was evaluated; findings indicated a high likelihood of having hyalinized arterioles if telangiectatic capillaries were also present (OR 31.67 [3.13, 320.06]). Microvascular changes in radiated tissue have previously been described in other anatomic subsites, but the larynx and pharynx have not been specifically evaluated. Laryngectomy mucosal margins appear to display similar changes, and evidence of this damage may be associated with fistula formation. These features could potentially guide the surgeon to alter the reconstructive technique.

RESUMEN

OBJECTIVE: To assess the characteristics and quality of cost utility analyses (CUA) related to otolaryngology within the CEA registry and to summarize their collective results. METHODS: All cost-utility analyses published between 1976 and 2011 contained in the Cost-Effectiveness Analysis Registry (CEA Registry) were evaluated. Topics that fall within the care of an otolaryngologist were included in the review regardless of the presence of an otolaryngologist author. Potential associations between various study characteristics and CEA registry quality scores were evaluated using the Pearson product moment correlation coefficient. RESULTS: Sixty-one of 2913 (2.1%) total CUA publications screened were related to otolaryngology. Eighteen of 61 (29.5%) publications included an otolaryngologist as an author. Fourteen studies agreed on the cost effectiveness of at least unilateral cochlear implantation and six of seven (85.7%) studies demonstrated the cost effectiveness of continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA). Forty-six percent (28 of 61) of all manuscripts were published between 2008 and 2011. A more recent publication year was associated with a higher CEA registry quality score while the presence of an otolaryngologist author and journal impact factor had no significant correlation with the quality of the CUA. CONCLUSION: Based on current evidence in the CEA registry, unilateral cochlear implantation for hearing loss and CPAP for OSA are both cost-effective therapeutic interventions. Although CUAs in otolaryngology have increased in quantity and improved in quality in more recent years, there is a relative lack of CUAs in otolaryngology in comparison to other subspecialties.

RESUMEN

IMPORTANCE: The optimal reconstruction of total glossectomy defects with or without total laryngectomy is controversial. Various pedicled and free tissue flaps have been advocated, but long-term data on functional outcomes are not available to date. OBJECTIVES: To compare various total glossectomy defect reconstructive techniques used by multiple institutions and to identify factors that may lead to improved long-term speech and swallowing function. DESIGN, SETTING, AND PARTICIPANTS: A multi-institutional, retrospective review of electronic medical records of patients undergoing total glossectomy at 8 participating institutions between June 1, 2001, and June 30, 2011, who had a minimal survival of 2 years. INTERVENTION: Total glossectomy with or without total laryngectomy. MAIN OUTCOMES AND MEASURES: Demographic and surgical factors were compiled and correlated with speech and swallowing outcomes. RESULTS: At the time of the last follow-up, 45% (25 of 55) of patients did not have a gastrostomy tube, and 76% (42 of 55) retained the ability to verbally communicate. Overall, 75% (41 of 55) of patients were tolerating at least minimal nutritional oral intake. Feeding tube dependence was not associated with laryngeal preservation or the reconstructive techniques used, including flap suspension, flap innervation, or type of flap used. Laryngeal preservation was associated with favorable speech outcomes, such as the retained ability to verbally communicate in 97% of those not undergoing total laryngectomy (35 of 36 patients) vs 44% (7 of 16) in those undergoing total laryngectomy (P < .001), as well as those not undergoing total laryngectomy achieving some or all intelligible speech in 85% (29 of 34 patients) compared with 31% (4 of 13) undergoing total laryngectomy achieving the same intelligibility (P < .001). CONCLUSIONS AND RELEVANCE: In patients with total glossectomy, feeding tube dependence was not associated with laryngeal preservation or the reconstructive technique, including flap innervation and type of flap used. Laryngeal preservation was associated with favorable speech outcomes such as the retained ability to verbally communicate and higher levels of speech intelligibility.

RESUMEN

OBJECTIVE: To compare the different modalities for treatment of Zenker's diverticulum and the associated clinical outcomes. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care hospital. SUBJECTS AND METHODS: Between 1995 and 2011, 164 patients underwent surgery for Zenker's diverticulum (stapler, n = 69; laser, n = 68; open, n = 27). Patient sociodemographics, medical comorbidities, pre- and postoperative subjective dysphagia and regurgitation score, complications, length of stay, time to oral intake, and recurrence were reviewed for each surgical modality. RESULTS: No statistically significant difference in diverticulum prevalence was associated with age, gender, or treatment group. Mean length of hospital stay was not significantly different between the 3 groups (P = .14). A significant difference in time to oral intake was observed in the laser group compared with the other 2 groups (P = .012). No significant difference in recurrence (P = .21) or complication (P = .12) rates was identified between the 3 groups. Although all 3 groups demonstrated a significant decrease between preoperative and postoperative dysphagia and regurgitation scores, the degree of improvement was not significant when the 3 groups were compared. CONCLUSION: There is no single "best" approach to Zenker's diverticulum. The open, laser, and stapler methods are equally effective and have similar complication rates.

RESUMEN

BACKGROUND: Traumatic tracheal injury via blunt or penetrating mechanism comes with a grave prognosis. Cricotracheal separation is a rare entity among these injuries and even more infrequent by means of penetrating trauma. Resultant airway discontinuity subsequent to these insults causes immense global hypoxia and tends to be uniformly fatal. OBJECTIVE: Our aim was to discuss emergent and surgical management of traumatic airway injury. CASE REPORT: We report the case of a 28-year-old male who sustained a gunshot wound to the neck resulting in laryngeal fracture and cricotracheal separation. We review the initial stabilization of his airway and detail the successive surgical management of his injury in the context of the current available literature, with an emphasis on timely airway stabilization when high suspicion for cricotracheal separation exists based on traumatic mechanism. CONCLUSIONS: Emergent management and stabilization of the airway is critical to survival in the context of trauma involving the neck and airway structures.
