RESUMEN

OBJECTIVES: Primary objective: describe rates of 30-days unplanned readmission following outpatient resection of oral cavity cancer. Secondary objective: evaluate for patient and treatment factors associated with readmission. METHODS: Retrospective, dual-institution cohort study of 2 tertiary care referral centers involving adult patients undergoing resection of oral cavity cancer with plans for same-day discharge. Consecutive sample of 77 patients included. Primary outcome was unplanned readmission to emergency room or inpatient stay in the 30 days following surgery. Comparison testing was used between return and non-return groups. RESULTS: Among 77 patients treated with outpatient surgery for oral cavity cancer, 19 (25%) returned to the hospital within 30 days. Among the reasons for return, 16 (80%) were directly related to surgery, and 4 (20%) were related to perioperative medical complications not directly related to a surgical site. Among the 25 patients also undergoing sentinel lymph node biopsy with their oral cavity resection, none returned to the hospital for neck-related complications. While most patients could be safely observed and discharged after return to the hospital, 8 patients (10%) required inpatient readmission. No significant differences between return and non-return groups were identified, although there was a trend toward shorter driving distance from hospital for the return group (47.6 miles vs. 69.5 miles, P = 0.097). CONCLUSION: Unplanned return to the hospital following outpatient oral cavity resection is prevalent and primarily driven by postoperative primary resection site concerns. Among patients selected for same day discharge, no definite population at highest risk of unplanned return was identified.

RESUMEN

PURPOSE: Factors that are associated with failure to receive guideline-compliant adjuvant chemotherapy after resection of high-risk oral cavity cancer are understudied. Here, we performed a retrospective cohort study of surgically treated patients with oral cavity squamous cell carcinoma to determine rates of guideline-compliant adjuvant chemotherapy and to examine patient factors associated with receiving guideline-compliant chemotherapy. STUDY DESIGN: Retrospective cohort. SETTING: Two tertiary care referral centers. METHODS: Patients with resected high-risk oral cavity squamous cell carcinoma and known adjuvant therapy details were included. Extranodal extension or positive margins were considered high-risk features for which adjuvant chemoradiation was indicated. Patient factors were examined to determine associations with receiving on-guidelines treatment. Univariable and multivariable logistic regression were used to determine significance of associations. RESULTS: 75 patients were included. 36 (48 %) patients received guideline-compliant cisplatin. In total, 39 (52 %) patients did not receive guideline-compliant chemotherapy. On multivariable analysis, meeting with a university medical oncologist was significantly associated with the receipt of guideline-compliant cisplatin (OR 6.38, 95 % CI 2.26-20.0, p < 0.001). CONCLUSION: Adherence to on-guidelines treatment can be difficult to achieve in patients with advanced stage head and neck cancer. Meeting with university medical oncology is associated with an increased chance of receiving guideline-compliant chemotherapy.

RESUMEN

OBJECTIVE: Positive surgical margins in oral cavity squamous cell carcinoma are associated with cost escalation, treatment intensification, and greater risk of recurrence and mortality. The positive margin rate has been decreasing for cT1-T2 oral cavity cancer over the past 2 decades. We aim to evaluate positive margin rates in cT3-T4 oral cavity cancer over time, and determine factors associated with positive margins. STUDY DESIGN: Retrospective analysis of a national database. SETTING: National Cancer Database 2004 to 2018. METHODS: All adult patients diagnosed between 2004 and 2018 who underwent primary curative intent surgery for previously untreated cT3-T4 oral cavity cancer with known margin status were included. Logistic univariable and multivariable regression analyses were performed to identify factors associated with positive margins. RESULTS: Among 16,326 patients with cT3 or cT4 oral cavity cancer, positive margins were documented in 2932 patients (18.1%). Later year of treatment was not significantly associated with positive margins (odds ratio [OR] 0.98, 95% confidence interval [CI] 0.96-1.00). The proportion of patients treated at academic centers increased over time (OR 1.02, 95% CI 1.01-1.03). On multivariable analysis, positive margins were significantly associated with hard palate primary, cT4 tumors, advancing N stage, lymphovascular invasion, poorly differentiated histology, and treatment at nonacademic or low-volume centers. CONCLUSION: Despite increased treatment at academic centers for locally advanced oral cavity cancer, there has been no significant decrease in positive margin rates which remains high at 18.1%. Novel techniques for margin planning and assessment may be required to decrease positive margin rates in locally advanced oral cavity cancer.

RESUMEN

OBJECTIVE: Patient factors associated with failure to receive adjuvant therapy after oral cavity cancer resection remain understudied. Here, we identified rates of missed adjuvant therapy, determined factors associated with missed therapy, and assessed associations with survival. STUDY DESIGN: Retrospective cohort. SETTING: National Cancer Database. METHODS: Patients with resected oral cavity squamous cell carcinoma and known adjuvant therapy status were included. T3-4 stage, N2-3 stage, and lymphovascular invasion were considered indications for adjuvant radiation. Extranodal extension or positive margins were considered indications for chemoradiation. Patient factors were examined for associations with missed adjuvant therapy. Overall survival was evaluated by Cox proportional hazard analysis. RESULTS: A total of 53,503 patients were included. 27.5% missed adjuvant therapy altogether, and 26.7% with a documented indication for chemoradiation missed chemotherapy. Factors associated with missed adjuvant therapy were age, white race, low income, metropolitan population, increasing comorbidities, travel distance, lip primary, and treatment at the academic facility. Factors associated with missed chemotherapy were age, female sex, nontongue subsite, and treatment at a nonacademic center. Among patients with indications for adjuvant radiation, missed radiation was associated with worse overall survival (hazard ratio [HR]: 1.42, 95% confidence interval [CI]: 1.31-1.53). Among patients with indications for adjuvant chemoradiation, missed chemotherapy was associated with worse overall survival (HR: 1.19, 95% CI: 1.09-1.29). CONCLUSION: Missed adjuvant therapy occurs frequently after oral cavity resection. Patients treated at academic centers may be at risk of missed therapy related to travel distance, though these patients are more likely to receive adjuvant chemotherapy when indicated. Missed adjuvant therapy is associated with worse survival.

RESUMEN

OBJECTIVES: Compare the rates of post-operative chyle leak following therapeutic lateral neck dissection during treatment of papillary thyroid carcinoma (PTC) versus squamous cell carcinoma (SCC) of the head and neck. METHODS: A retrospective analysis of 226 consecutive neck dissections in 201 patients who underwent therapeutic neck dissection involving at least levels II-IV with a final pathologic diagnosis of mucosal SCC of the head and neck or PTC from 2010 to 2020. Specific cases of chyle leak were reviewed. Surgical factors associated with chyle leak were analyzed using logistic regression analysis. Duration of chyle leak was assessed by the Kaplan-Meier curve, and time-to-resolution was analyzed by Cox proportional hazard analysis. RESULTS: Postoperative chyle leak was encountered in 15 (6.6%) neck dissections, eight (12.3%) in PTC, and seven (4.3%) in SCC. High-volume chyle leak and chyle leak requiring operative intervention were only encountered in neck dissections performed for PTC. Chyle leak was significantly associated with PTC on univariable analysis (OR 3.08, p = 0.037), but not on multivariable analysis (OR 1.35, p = 0.711). High-volume chyle leak and the need for operative intervention were associated only with PTC patients (OR 23.6, p = 0.006; OR 18.09, p = 0.023 respectively). Median duration of chyle leak was 12.1 days among patients with SCC, and 20.5 days among patients with PTC (p = 0.089). CONCLUSIONS: Among 201 patients undergoing therapeutic neck dissection, chyle leak was associated with PTC pathology on univariable but not multivariable analysis. However, high-volume leaks and leaks requiring operative intervention only occurred among patients with PTC. LEVEL OF EVIDENCE: level III Laryngoscope, 133:2959-2964, 2023.

RESUMEN

OBJECTIVE: Patients with recurrent oropharyngeal cancer can achieve survival benefits from surgical salvage, and often require simultaneous free-flap reconstruction. Resection and reconstruction can impact function, leading to tube dependence. PRIMARY OBJECTIVE: describe rates of tracheostomy and gastrostomy tube dependence after oropharyngeal resection and free flap after prior radiation. SECONDARY OBJECTIVE: evaluate patient, tumor, and treatment factors associated with tube dependence. STUDY DESIGN: Retrospective, multi-institutional cohort study. Patients treated from 2003 to 2020. Average follow-up 21.4 months. SETTING: Five tertiary care centers. METHODS: Consecutive cohort of patients undergoing resection and simultaneous free-flap reconstruction for oropharyngeal squamous cell carcinoma after head and neck radiation. PRIMARY OUTCOMES: gastrostomy tube dependence and tracheostomy or tracheostoma 1 year after surgery. Univariable and multivariable logistic regression were performed to identify factors associated with dependence. RESULTS: 89 patients underwent oropharyngectomy and free-flap reconstruction; 18 (20%) underwent total laryngectomy as part of tumor extirpation. After surgery, 51 patients (57%) lived 12 months. Among patients alive at 12 months, 22 (43%) were at least partially-dependent on gastrostomy tube, and 15 (29%) had either tracheostomy or tracheostoma. On multivariable analysis, extensive glossectomy (OR 16.6, 95% CI 1.83-389, p = 0.026) and total laryngectomy (OR 11.2, 95% CI 1.71-105, p = 0.018) were associated with long-term gastrostomy tube. No factors were associated with long-term tracheostomy on multivariable analysis. CONCLUSION: Even among long-term survivors after salvage resection and free-flap reconstruction, rates of tube dependence are significant. This multi-institutional review is the largest such study to the date and may help inform shared decision-making. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2141-2147, 2023.

RESUMEN

OBJECTIVE: To assess whether preoperative tracheostomy (PreOT) increases risk of complications after total laryngectomy (TL) and to determine if timing of tracheostomy creation is associated with an increased risk. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care hospital between 2007 and 2020. METHODS: Inclusion criteria were patients who underwent primary or salvage TL for oncologic treatment. Dependent variables of interest included surgical complications, such as wound dehiscence, infection, hematoma, complete flap failure, fistula formation, and stoma stenosis, as well as medical complications. Categorical variables were compared with chi-square test or Fisher exact test, and continuous variables were compared with an independent t test. Multivariable regression was conducted to assess predictors of complications after laryngectomy. RESULTS: A total of 306 patients were included. Primary TL was performed in 161 (53%) patients and salvage in 145 (47%) patients. Of the patients undergoing primary laryngectomy, 105 (65%) received a PreOT. Of the patients undergoing salvage laryngectomy, 86 (59%) received a PreOT. In both primary and salvage cases, there was no association between PreOT and surgical or medical complications. Additionally, there was no significant association between timing of tracheostomy and surgical complications. On multivariable analysis, the presence of a PreOT was not associated with surgical complications. In salvage cases, those with a PreOT had a significantly longer average length of stay than those without a PreOT (12 vs 9 days, P = .008). CONCLUSION: PreOT in patients undergoing primary and salvage laryngectomies was not associated with surgical or medical complications postlaryngectomy. Timing of tracheostomy in relation to laryngectomy was not found to adversely affect clinical outcomes.

RESUMEN

OBJECTIVES: (1) Evaluate the association of flap type with late complications in patients undergoing osseous head and neck reconstruction with the fibula free flap (FFF), osteocutaneous radial forearm free flap (OCRFFF), and scapula free flap (SFF). (2) Compare the prevalence of late complications based on minimum duration of follow-up. STUDY DESIGN: Retrospective cohort study. SETTING: Multiple academic medical centers. METHODS: Patients undergoing FFF, OCRFFF, or SFF with ≥6-month follow-up were stratified by type of flap performed. The association of flap type with late complications was analyzed via univariable and multivariable logistic regression, controlling for relevant clinical risk factors. Additionally, the frequency of late complications by minimum duration of follow-up was assessed. RESULTS: A total of 617 patients were analyzed: 312 (50.6%) FFF, 230 (37.3%) OCRFFFF, and 75 (12.2%) SFF. As compared with the SFF, the FFF (adjusted odds ratio [aOR], 3.05; 95% CI, 1.61-5.80) and OCRFFF (aOR, 2.17; 95% CI, 1.12-4.22) were independently associated with greater odds of overall late recipient site wound complications. The SFF was independently associated with the lowest odds of hardware exposure when compared with the FFF (aOR, 2.61; 95% CI, 1.27-5.41) and OCRFFF (aOR, 2.38; 95% CI, 1.11-5.12). The frequency of late complications rose as minimum duration of follow-up increased until plateauing at 36 months. CONCLUSIONS: This multi-institutional study suggests that the long-term complication profile of the SFF and OCRFFF compares favorably to the FFF. The SFF may be associated with the fewest overall late recipient site complications and hardware exposure, while the FFF may be associated with the most of these 3 options.

RESUMEN

Importance: Studies comparing perioperative outcomes of fibula free flaps (FFFs), osteocutaneous radial forearm free flaps (OCRFFFs), and scapula free flaps (SFFs) have been limited by insufficient sample size. Objective: To compare the perioperative outcomes of patients who underwent FFFs, OCRFFFs, and SFFs. Design, Setting, and Participants: This cohort study assessed the outcomes of 1022 patients who underwent FFFs, OCRFFFs, or SFFs for head and neck reconstruction performed at 1 of 6 academic medical centers between January 2005 and December 2019. Data were analyzed from September 17, 2021, to June 9, 2022. Main Outcomes and Measures: Patients were stratified based on the flap performed. Evaluated perioperative outcomes included complications (overall acute wound complications, acute surgical site infection [SSI], fistula, hematoma, and flap failure), 30-day readmissions, operative time, and prolonged hospital length of stay (75th percentile, >13 days). Patients were excluded if data on flap type or clinical demographic characteristics were missing. Associations between flap type and perioperative outcomes were analyzed using logistic regression, after controlling for other clinically relevant variables. Adjusted odds ratios (aORs) with 95% CIs were generated. Results: Perioperative outcomes of 1022 patients (mean [SD] age, 60.7 [14.5] years; 676 [66.1%] men) who underwent major osseous head and neck reconstruction were analyzed; 510 FFFs (49.9%), 376 OCRFFFs (36.8%), and 136 SFFs (13.3%) were performed. Median (IQR) operative time differed among flap types (OCRFFF, 527 [467-591] minutes; FFF, 592 [507-714] minutes; SFF, 691 [610-816] minutes). When controlling for SSI, FFFs (aOR, 2.47; 95% CI, 1.36-4.51) and SFFs (aOR, 2.95; 95% CI, 1.37-6.34) were associated with a higher risk of flap loss than OCRFFFs. Compared with OCRFFFs, FFFs (aOR, 1.77; 95% CI, 1.07-2.91) were associated with a greater risk of fistula after controlling for the number of bone segments and SSI. Both FFFs (aOR, 1.77; 95% CI, 1.27-2.46) and SFFs (aOR, 1.68; 95% CI, 1.05-2.69) were associated with an increased risk of 30-day readmission compared with OCRFFFs after controlling for Charlson-Deyo comorbidity score and acute wound complications. Compared with OCRFFFs, FFFs (aOR, 1.78; 95% CI, 1.25-2.54) and SFFs (aOR, 1.96; 95% CI, 1.22-3.13) were associated with a higher risk of prolonged hospital length of stay after controlling for age and flap loss. Conclusions and Relevance: Findings of this cohort study suggest that perioperative outcomes associated with OCRFFFs compare favorably with those of FFFs and SFFs, with shorter operative times and lower rates of flap loss, 30-day readmissions, and prolonged hospital length of stay. However, patients undergoing SFFs represented a more medically and surgically complex population than those undergoing OCRFFFs or FFFs.

RESUMEN

OBJECTIVE: Review QOL outcomes among patients undergoing segmental mandibulectomy and bony free flap reconstruction for ONJ. DATA SOURCES: PubMed was searched for MeSH terms "Quality of life," "Osteonecrosis," "Osteoradionecrosis," "Bisphosphonate-associated osteonecrosis of the jaw," "Free tissue flaps," and "Mandibular reconstruction." REVIEW METHODS: English language studies with QOL outcomes data for patients undergoing free flap reconstruction for advanced ONJ were included. 197 records were initially screened; 18 full texts assessed; 10 full texts included. PRISMA guidelines were followed. RESULTS: Ten studies were included in this systematic review: six retrospective, three retrospective with comparison groups, and one prospective. In studies with comparison groups, ONJ patients have worse self-reported QOL than the general population as well as head and neck cancer patients without ONJ. Nearly all patients with QOL measurements (220/235 patients) had ONJ from prior radiation. Segmental mandibulectomy and bony free flap improved overall QOL in over half of patients, as well as pain associated with ONJ in 70-75 % of patients. Surgery did not improve long-term effects of radiation such as chewing, swallowing, and salivary production. Donor site morbidity rarely affects QOL. CONCLUSIONS: Osteonecrosis of the jaw (ONJ) worsens quality-of-life, and advanced disease often requires segmental mandibulectomy and bony free flap reconstruction. Patients and surgeons may expect improvement in some, but not all, domains of patient-reported QOL by the use of segmental mandibulectomy and reconstruction for advanced ONJ.

RESUMEN

Tuft cells are bottle-shaped, microvilli-projecting chemosensory cells located in the lining of a variety of epithelial tissues and, following their identification approximately 60 years ago, have been linked to immune system function in a variety of epithelia. Until recently, Tuft cells had not been convincingly demonstrated to be present in salivary glands with their detection by transmission electron microscopy only shown in a handful of earlier studies using rat salivary glands, and no follow-up work has been conducted to verify their presence in salivary glands of other species. Here, we demonstrate that Tuft cells are present in the submandibular glands of various species (i.e., mouse, pig and human) using transmission electron microscopy and confocal immunofluorescent analysis for the POU class 2 homeobox 3 (POU2F3), which is considered to be a master regulator of Tuft cell identity.

RESUMEN

OBJECTIVES: The mechanisms of perineural invasion (PNI) in oral cavity squamous cell carcinoma are only partially understood, and no studies have specifically investigated the role of perineural fibroblasts in PNI. Here, we identified fibroblasts within the microenvironment of perineural invasion and assessed their expression of matrix metalloproteinase-2 (MMP-2). MATERIALS AND METHODS: Tumor specimens from 12 patients with oral cavity squamous cell carcinoma and pathologically-confirmed perineural invasion were stained by immunohistochemistry (IHC) for vimentin (positive control) and MMP-2. Scoring was quantified and compared at nerves involved with PNI and nerves uninvolved with PNI. RESULTS: All 12 patients had perineural fibroblasts around involved and uninvolved nerves as marked by vimentin IHC staining. Perineural fibroblasts had detectable MMP-2 expression at areas of perineural invasion in all 12 patients, but no patients had MMP-2 expression by fibroblasts at nerves without PNI. CONCLUSION: MMP-2 is expressed by fibroblasts within the microenvironment of perineural invasion, and MMP-2 expression by fibroblasts is a possible mechanism of perineural invasion by oral cavity squamous cell carcinoma. MMP-2 may be an anti-cancer target among oral cavity squamous cell carcinoma patients with PNI.

RESUMEN

OBJECTIVE: To report a very rare case of incidentally discovered Medullary Thyroid Carcinoma after total thyroidectomy in a patient with Graves' disease, review available literature, and present readers with management information. RESULTS: Medullary Thyroid Carcinoma in the setting of Graves' disease is a rare scenario. Only fifteen total cases besides ours has been described in literature, and only six other cases were incidentally discovered. CONCLUSIONS: When Medullary Thyroid Carcinoma is incidentally discovered in the setting of Graves' disease, retroactive workup should begin with postoperative calcitonin, CEA level, testing for RET mutation, and a comprehensive neck ultrasound as soon as the diagnosis is made.

RESUMEN

OBJECTIVES: To define rates of occult metastases in salvage oral cavity and oropharyngeal cancer resection requiring free flap, to examine the location of occult metastases, and to determine associations between occult metastasis and survival. STUDY DESIGN: Retrospective cohort study. SETTING: Two tertiary care referral centers. METHODS: We identified previous cases of irradiation with recurrent or second primary oral cavity or oropharyngeal squamous cell carcinoma that had no evidence of regional metastasis and required free tissue transfer reconstruction of the primary site. Patients who underwent elective neck dissection or exploration were reviewed. The main outcome measures were the presence and location of occult nodal metastasis. Disease-free survival and overall survival were measured. Odds ratios and hazard ratios were used for analysis. RESULTS: A total of 83 patients were included: 52 with oral cavity primary tumors and 31 with oropharynx. An overall 78 (94%) underwent elective salvage neck dissection. Occult metastases were found in 9 (11.5%) patients. The most common nodal station for occult metastasis was level 2. Neither elective neck dissection nor the presence of occult metastasis was significantly associated with regional disease-free or overall survival. Oropharyngeal primary tumors were associated with higher risk of occult metastasis (odds ratio, 1.38; P < .01) and worse overall survival (hazard ratio, 2.09; P = .01). CONCLUSION: There is a low incidence of occult metastasis in postradiated recurrent or second primary oral cavity and oropharyngeal tumors. Elective neck dissection and occult nodal metastases were not associated with regional or overall survival. This series may help surgeons make decisions regarding the extent of neck surgery after prior radiation, especially when free flap reconstruction is required.

IMPORTANCE: Patients with either local recurrence of head and neck cancer or osteoradionecrosis after prior radiation treatment often require free tissue transfer for optimal reconstruction. In this setting, neck exploration for vessels is necessary, and an "incidental" neck dissection is often accomplished despite clinically negative cervical lymph nodes. While neck surgery in the post-radiated setting is technically challenging, the safety of post-radiated elective neck dissection or neck exploration for vessels is not well-studied, especially for patients undergoing non-laryngectomy salvage resections. OBJECTIVE: To define intraoperative and postoperative surgical complications for patients undergoing elective neck dissection or exploration with free tissue transfer reconstruction in the post-radiated setting, with attention to complications from neck surgery. DESIGN: Retrospective cohort study. Patient charts from May 2005 to April 2020 were reviewed. SETTING: Tertiary care referral center. PARTICIPANTS: Patients underwent free tissue transfer after prior head and neck irradiation for non-laryngeal local cancer recurrence or second primary, osteoradionecrosis, or for sole reconstructive purposes. Patients with clinically positive neck disease were excluded. MAIN OUTCOMES AND MEASURES: Intraoperative and postoperative complications including unplanned vessel or nerve injury, hematoma, chyle leak, wound dehiscence, wound infection, fistula formation, flap failure, and perioperative medical complications. Neck exploration and neck dissection patient outcomes were compared by Fisher exact test. RESULTS: Seventy-two patients (56 men and 16 women) of average age sixty-one (range 34-89) were identified with average follow-up 25.7 months. Most patients (78%) underwent salvage neck dissection, and the rest underwent neck exploration for vessels only. There were five intraoperative neck complications: three vessel injuries and two nerve injuries. There were twenty-six postoperative surgical complications among eighteen patients. There was no difference in surgical complications whether patients underwent neck dissection or exploration only. Two partial and two complete flap failures occurred. There were nine perioperative medical complications among six patients. CONCLUSIONS AND RELEVANCE: Elective neck dissection or exploration among patients undergoing free tissue transfer in the post-radiated setting carries a risk of both intraoperative and postoperative surgical complications. The present study defines risk of complications and helps to inform patient discussions for risk of complications in the post-radiated setting.

RESUMEN

OBJECTIVE: Orocutaneous fistula (OCF) after reconstruction for oral cavity resection can lead to prolonged hospitalization and adjuvant treatment delay. Few studies have examined factors leading to OCF after oral cavity resection. Primary objective: evaluate overall incidence and factors associated with OCF after oral cavity reconstruction. DATA SOURCES: Scopus 1960-database was searched for terms: "orocutaneous fistula," "oro cutaneous fistula," "oral cutaneous fistula," "orocervical fistula," "oral cavity salivary fistula." REVIEW METHODS: English language studies with >5 patients undergoing reconstruction after oral cavity cancer resection were included. About 1057 records initially screened; 214 full texts assessed; 78 full-texts included. PRISMA guidelines were followed, and MINORS criteria used to assess risk of bias. Data were pooled using random-effects model. Primary outcome was OCF incidence. Meta-analysis to determine the effect of preoperative radiation on OCF conducted on 12 eligible studies. Pre-collection hypothesis was that prior radiation therapy is associated with increased OCF incidence. Post-collection analyses: free versus pedicled flaps; mandible-sparing versus segmental mandibulectomy. RESULTS: Seventy-eight studies were included in meta-analysis of overall OCF incidence. Pooled effect size showed overall incidence of OCF to be 7.71% (95% CI, 6.28%-9.13%) among 5400 patients. Meta-analysis of preoperative radiation therapy on OCF showed a pooled odds ratio of 1.68 (95% CI, 0.93-3.06). OCF incidence was similar between patients undergoing free versus pedicled reconstruction, or segmental mandibulectomy versus mandible-sparing resection. CONCLUSION: Orocutaneous fistula after oral cavity resection has significant incidence and clinical impact. Risk of OCF persists despite advances in reconstructive options; there is a trend toward higher risk after prior radiation.

RESUMEN

OBJECTIVES: Determine if Mohs micrographic surgery (MMS) is associated with improved overall survival compared to wide local excision (WLE) when treating cutaneous melanoma of the head and neck (CMHN) and to report the proportion of patients treated with MMS versus WLE who also underwent sentinel lymph node biopsy (SLNB). METHODS: Retrospective cohort study of the National Cancer Database (NCDB) analyzing the overall survival of patients diagnosed with T1 to T4 CMHN between 2004 and 2016 who were treated with either WLE or MMS. RESULTS: On multivariable analysis, treatment with WLE versus MMS was not significantly associated with overall survival (HR, 1.094; 95% CI, 0.997-1.201). On multivariable analysis, lower Charlson-Deyo score (HR, 0.489; 95% CI, 0.427-0.560), negative margins (HR, 0.754; 95% CI, 0.705-0.807), and N0 classification (HR 0.698; 95% CI, 0.668-0.730) were associated with improved overall survival. Seventy-seven percent of patients treated with MMS did not undergo SLNB, while 45% of patients treated with WLE did not undergo SLNB (P < .001). CONCLUSIONS: No difference in overall survival between MMS and WLE when treating CMHN. Patients treated with MMS were significantly less likely to undergo SLNB, suggesting an opportunity for enhancement of multidisciplinary care.
