RESUMO

Importance: Oral and oropharyngeal cancer have low survival rates, and incidence continues to increase. Objective: To determine whether soluble CD44 and total protein (TP) are useful for monitoring head and neck cancer recurrence, either used in a point-of-care (POC) test or as individual laboratory-based biomarkers. Design, Setting, and Participants: This multi-institutional nonrandomized clinical trial testing a novel diagnostic/screening assay took place across the University of California, San Diego; Johns Hopkins University; the Greater Baltimore Medical Center; New York University; and the San Diego Veterans Affairs Hospital. Patients with newly biopsy-proven, untreated oral cavity and oropharyngeal cancer were enrolled. Patients were enrolled April 2017 to April 2019, and data were analyzed December 2022 to June 2023. Exposure: POC salivary oral rinse test. Main Outcomes and Measures: Oral rinses were collected at pretreatment baseline and 3, 6, 12, and 18 months after completion of therapy; participants were then followed up for 3 years to define disease status. Associations of baseline characteristics with a positive test were evaluated by Fisher exact test. The association of a positive value on the CD44 or TP test with progression-free survival was evaluated in an adjusted multivariable proportional hazards model. Results: Of 172 patients enrolled, the mean (SD) age was 62.5 (10.2) years, and 122 (70.9%) identified as male. Additionally, 92 patients (53.3%) had never smoked, 99 (57.6%) formerly or currently drank alcohol, and 113 (65.7%) presented with oropharyngeal cancers, which were positive for human papillomavirus in 95 (84.1%). Tumor site was associated with test results at baseline; patients with oral cavity cancer had a higher baseline positive POC test rate (47 of 51 [92.2%]) compared to patients with oropharyngeal cancer (85 of 110 [77.3%]). Using Cox regression models with CD44 or TP level as a time-varying covariate, a higher CD44 level showed a statistically significant association with a higher hazard of recurrence (hazard ratio, 1.06; 95% CI, 1.00-1.12), though the TP level was not statistically significant. In multivariate adjusted analysis, higher CD44 and TP levels were associated with increased hazard ratios of recurrence of 1.13 (95% CI, 1.04-1.22) and 3.51 (95% CI, 1.24-9.98), respectively. Conclusion and Relevance: In this multi-institutional nonrandomized clinical trial of an assay, posttreatment longitudinal monitoring for elevated salivary CD44 and TP levels using an enzyme-linked immunosorbent assay-based laboratory test identified patients at increased risk of future cancer recurrence. The CD44 and TP rapid POC test holds some promise, but further development is needed for this indication. Trial Registration: ClinicalTrials.gov Identifier: NCT03148665.

RESUMO

BACKGROUND AND PURPOSE: Mandibulectomy remains the treatment of choice for oral cavity squamous cell carcinoma with infiltration of bone and for benign tumors with full mandibular thickness involvement. Although bone resection margins are critical for patient outcomes, intraoperative immediate bone margins assessment is inadequate, and few alternative options have been described. The purpose of this study was to describe the use of an existing intraoperative radiographic system for objective determination of bone resection margins during mandibulectomy. METHODS: We conducted a retrospective case series of all patients at the Greater Baltimore Medical Center who underwent mandibulectomy and received intraoperative Faxitron radiography from January 1, 2016, to March 1, 2019. Patient characteristics including age, sex, diagnosis, tumor location, clinical and pathologic stage, procedure performed, and bone resection margins were reviewed. RESULTS: A total of 10 patients underwent mandibulectomy with intraoperative radiography. Nine (90%) received surgery for squamous cell carcinoma, with 1 (10%) for ameloblastoma. Out of those with squamous cell carcinoma, tumor location varied, and all were clinically stage T4. Final pathologic margins were negative in all cases (10/10), though in 2 cases, close margins were assessed intraoperatively, leading to further resection or change in operative plan. CONCLUSION: Intraoperative radiographic assessment of bone resection margins is a promising technique, though further validation is required.

RESUMO

Head and neck cancer (HNC) guidelines recommend regular multidisciplinary team (MDT) monitoring and early intervention to optimize dysphagia outcomes; however, many factors affect the ability to achieve these goals. The aims of this study were to explore the barriers/facilitators to establishing and sustaining a MDT HNC care pathway and to examine the dysphagia-related speech-language pathology (SLP) and dietetic components of the pathway. Using the Consolidated Framework for Implementation Research (CFIR), a mixed methods study design was used to evaluate an established MDT HNC pathway. Ten MDT members provided perceptions of facilitators/barriers to implementing and sustaining the pathway. Patients attending the SLP and dietetic components of the pathway who commenced treatment between 2013 and 2014 (n = 63) were audited for attendance, outcome data collected per visit, and swallowing outcomes to 24-month post-treatment. Dysphagia outcomes were compared to a published cohort who had received intensive prophylactic dysphagia management. Multiple CFIR constructs were identified as critical to implementing and sustaining the pathway. Complexity was a barrier. Patient attendance was excellent during treatment, with low rates of non-compliance (< 15%) to 24 months. Collection of clinician/patient outcome tools was good during treatment, but lower post-treatment. Dysphagia outcomes were good and comparable to prior published data. The pathway provided patients with access to regular supportive care and provided staff opportunities to provide early and ongoing dysphagia monitoring and management. However, implementing and sustaining a HNC pathway is complex, requiring significant staff resources, financial investment, and perseverance. Regular audits are necessary to monitor the quality of the pathway.

RESUMO

OBJECTIVE: To examine reader performance in evaluating oropharyngeal anatomy on ultrasonography. MATERIALS AND METHODS: Ultrasound images of the oropharynx comprising normal and malignant anatomic variants were organized into slideshows. Slideshows were administered to 6 readers blinded to participant tumor status and with varying experience reading oropharyngeal sonograms. A training slideshow oriented readers to images of the oropharynx with and without malignant lesions. Readers then evaluated images in a test slideshow for tumor presence and marked orthogonal long and short dimensions of the tumor. Results were analyzed for accuracy, sensitivity, specificity, inter-reader agreement, and measurement error relative to prospectively-identified reference measurements. RESULTS: Eighty-seven percent of base of tongue (BOT) sonograms were identified correctly by a majority of readers. In identifying BOT tumors, median accuracy, sensitivity, specificity, and Fleiss's kappa were 79%, 73%, 85%, and 0.51, respectively. Median measurement error in the long and short axes for BOT tumors was -2.6% (range: -40% to 29%) and -2.6% (range: -56% to 156%), respectively. Eighty-four percent of palatine tonsil sonograms were identified correctly by a majority of readers. In identifying tonsil tumors, median accuracy, sensitivity, specificity, and Fleiss's kappa were 77%, 74%, 78%, and 0.41, respectively. Median measurement error in the long and short axes for tonsil tumors was 3.8% (range: -45% to 32%) and -6.5% (range: -83% to 42%), respectively. CONCLUSIONS: Overall, US has clinically useful sensitivity for identification of oropharyngeal carcinoma among readers of diverse clinical backgrounds and experience. US may be useful for the evaluation of features such as tumor dimensions.

RESUMO

Evidence supporting prophylactic swallow exercises for patients with head and neck cancer (HNC) has not been universally demonstrated. This RCT examined diet level, feeding tube use, swallow function, and quality of life (QOL) of patients undergoing chemoradiotherapy who performed prophylactic swallowing exercises. Sixty HNC patients were randomized into exercise versus control groups. Swallowing, oromotor, toxicity, and QOL data were recorded (baseline, 3, 6, 12, 24 months). Physiological swallow function was examined at baseline and 3 months. Swallow exercises were completed twice daily. Oral intake at 3 months was 10% better in the exercise group, which was not statistically significant (p = 0.49). Significant (p < 0.05) differences in secondary outcomes including oromotor function, pharyngeal impairment, oral pharyngeal swallow efficiency, and incisal opening were noted at early time points (3-6 months) in the exercise group. Possible positive early improvements in swallow function are associated with swallowing exercises, although these improvements are not significant longer term.

RESUMO

BACKGROUND: Despite its increasingly widespread adoption of transoral robotic surgery (TORS), there is still no uniform training curriculum. The purpose of this study was to describe the results of our novel TORS curriculum training program in which we introduce ex vivo dissection models for radical tonsillectomy and base of tongue (BOT) resections. METHODS: Prospective blinded data collection and objective assessment of a novel training curriculum. Trainee performance was evaluated on objective structured assessments of technical skills (OSATS) metrics, measured resection time, and margin analysis. Additionally, 4 expert TORS surgeons completed the ex vivo dissections. RESULTS: Trainees achieved OSATS scores similar to those of experts in both the BOT resection and radical tonsillectomy models. Peripheral and deep surgical margin measurements in the BOT model were significantly improved after training and were comparable to experts. CONCLUSION: This graduated curriculum provides a realistic training experience to develop competency with oropharyngeal resections before transition to the operating room. © 2016 Wiley Periodicals, Inc.

RESUMO

OBJECTIVE: Pharyngocutaneous fistula is a common complication in laryngectomy patients, particularly in previously irradiated cases. We initiated a comprehensive performance improvement intervention in all head and neck surgery patients intended to reduce postoperative infection and fistulae rates. We report our review of outcomes within laryngectomy patients. STUDY DESIGN: Case series with chart review. SETTING: Academic tertiary referral center. SUBJECTS: Nineteen laryngectomy patients at risk of postoperative fistula formation. METHODS: We reviewed the medical records of all patients who had undergone laryngectomy procedures between January 2013 and April 2014. Clinicodemographic data were obtained, including history of diabetes, prior radiation therapy, type of reconstruction performed for closure of the pharyngeal defect, and the presence or absence of postoperative fistula. RESULTS: The study population comprised 19 laryngectomy patients. Prior to implementation of our performance improvement intervention, 8 of 11 (73%) patients undergoing laryngectomy developed postoperative fistulae. After intervention, 0 of 8 patients developed fistulae (P = .002). Prior radiation, diabetes mellitus, and overall stage were not associated with a reduction in fistula rate (P > .05). CONCLUSION: Comprehensive uniform application of a standard antibiotic prophylaxis, surgical technique, perioperative care, and treatment of comorbid conditions can significantly reduce and potentially eliminate fistulae in laryngectomy patients who are especially at risk.

RESUMO

BACKGROUND: Human papillomavirus (HPV) tumor status and surgical salvage are associated with improved prognosis for patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC). Current data regarding types of surgery and the impact of surgery for patients with distant metastatic disease are limited. METHODS: A retrospective analysis of patients with recurrent OPSCC from 2 institutions between 2000 and 2012 was performed. p16 immunohistochemistry and/or in situ hybridization, as clinically available, were used to determine HPV tumor status. Clinical characteristics, distribution of recurrence site, and treatment modalities were compared by HPV tumor status. Overall survival (OS) was examined using Kaplan-Meier and Cox proportional hazards methods. RESULTS: The current study included 108 patients with 65 locoregional and 43 distant metastatic first recurrences. The majority of patients were HPV-positive (80 patients). HPV-positive tumor status was associated with longer time to disease recurrence (P<.01). Anatomic site distribution of disease recurrences did not differ by HPV tumor status. HPV-positive tumor status (adjusted HR [aHR], 0.23; 95% confidence interval [95% CI], 0.09-0.58 [P = .002]), longer time to disease recurrence (≥ 1 year; aHR, 0.36; 95% CI, 0.18-0.74 [P = .006]), and surgical salvage (aHR, 0.26; 95% CI, 0.12-0.61 [P = .002]) were found to be independently associated with OS after disease recurrence. Surgical salvage was independently associated with improved OS compared with nonsurgical treatment among patients with both locoregional (aHR, 0.15; 95% CI, 0.04-0.56 [P = .005]) and distant (aHR, 0.19; 95% CI, 0.05-0.75 [P = .018]) metastatic disease recurrences. CONCLUSIONS: Surgical salvage was found to be associated with improved OS for patients with recurrent locoregional and distant metastatic OPSCC, independent of HPV tumor status. Further prospective data are needed to confirm the role of surgical salvage for distant metastases.

RESUMO

PURPOSE: To determine if phosphodiesterase 5 (PDE5) inhibitors can augment immune function in patients with head and neck cancer through inhibition of myeloid-derived suppressor cells (MDSC). EXPERIMENTAL DESIGN: We performed a randomized, prospective, double blinded, placebo controlled, phase II clinical trial to determine the in vivo effects of systemic PDE5 inhibition on immune function in patients with head and neck squamous cell carcinoma (HNSCC). RESULTS: Tadalafil augmented immune response, increasing ex vivo T-cell expansion to a mean 2.4-fold increase compared with 1.1-fold in control patients (P = 0.01), reducing peripheral MDSC numbers to mean 0.81-fold change compared with a 1.26-fold change in control patients (P = 0.001), and increasing general immunity as measured by delayed type hypersensitivity response (P = 0.002). Tumor-specific immunity in response to HNSCC tumor lysate was augmented in tadalafil-treated patients (P = 0.04). CONCLUSIONS: These findings demonstrate that tadalafil augments general and tumor-specific immunity in patients with HNSCC and has therapeutic potential in HNSCC. Evasion of immune surveillance and suppression of systemic and tumor-specific immunity is a significant feature of head and neck cancer development. This study demonstrates that a PDE5 inhibitor, tadalafil, can reverse tumor-specific immune suppression in patients with head and neck cancer, with potential for therapeutic application.

RESUMO

PURPOSE: The purpose of this study was to determine the incidence of and risk factors for pharyngocutaneous fistula in patients undergoing total laryngectomy at a single institution. MATERIALS AND METHODS: The records of 59 patients undergoing primary or salvage total laryngectomy at our institution from 2001 to 2012 were retrospectively reviewed. Data collected included patient, tumor and treatment characteristics, and surgical technique. Risk factors were analyzed for association with pharyngocutaneous fistula formation. RESULTS: Twenty patients (34%) developed fistulas. Preoperative tracheostomy (OR 4.1; 95% CI 1.3-13 [p=0.02]) and low postoperative hemoglobin (OR 9.1; 95% CI 1.1-78 [p=0.04]) were associated with fistula development. Regarding surgical technique, primary sutured closure of the total laryngectomy defect had the lowest fistula rate (11%). In comparison, primary stapled closure and pectoralis onlay flap over primary closure had nonsignificantly increased fistula rates (43%, OR 6.0; 95% CI 1.0-37.3 [p=0.06] and 25%, OR 2.7; 95% CI 0.4-23.9 [p=0.38], respectively). Pectoralis flap incorporated into the suture line had a significantly increased fistula rate (50%, OR 7.1; 95% CI 1.4-46 [p=0.02]). After stratification for salvage status, patient comorbidities were associated with fistula in non-salvage cases whereas disease-related characteristics were associated with fistula in salvage cases. Fistula development was associated with increased length of hospital stay (p<0.001) and increased time before oral diet initiation (p<0.001). CONCLUSIONS: Pharyngocutaneous fistula is a common complication of total laryngectomy. Preoperative tracheostomy, postoperative hemoglobin, and surgical technique are important in determining the risk of fistula.

RESUMO

BACKGROUND: Although human papillomavirus detection in cervical lymph nodes of head and neck squamous cell cancers (HNSCC) of unknown primary site (UP) is indicative of a primary tumor of the oropharynx (OP), localization can remain elusive. Therefore, we investigated ultrasonography (US) for the identification of the primary tumor. METHODS: Eligible cases had HNSCC of UP after evaluation by a head and neck surgical oncologist. Controls were healthy volunteers. Transcervical and intraoral ultrasonography was performed by a standard protocol using convex (3.75-6.0 MHz and 5-7.5 MHz) transducers. US findings were compared with operative examination (exam under anesthesia, direct laryngoscopy) and biopsies. The primary outcome of interest was the presence or absence of a lesion on US. RESULTS: 10 cases and 20 controls were enrolled. PET/CT scans were negative/nonspecific (9), or suspicious (1) for a primary lesion. On US, predominantly hypoechoic (9 of 10) lesions were visualized consistent with base of tongue (n=7) or tonsil (n=3) primary tumors. On operative examination, 5 of 10 were appreciated. Two additional primaries were confirmed with biopsies "directed" by preoperative US. This represents an overall diagnostic rate of 70%, which is 20% higher than our detection rate for 2008-2010. The three cases in which a suspicious lesion was visualized on US, yet remained UP despite further interventions, could represent false positives, misclassification or operator variability. No lesions were suspected among the controls. CONCLUSION: Ultrasound has promise for detection of UPs of the OP and therefore warrants further investigation.

RESUMO

BACKGROUND: Base of tongue (BOT) is a difficult subsite to examine clinically and radiographically. Yet, anatomic delineation of the primary tumor site, its extension to adjacent sites or across midline, and endophytic vs. exophytic extent are important characteristics for staging and treatment planning. We hypothesized that ultrasound could be used to visualize and describe BOT tumors. METHODS: Transcervical ultrasound was performed using a standardized protocol in cases and controls. Cases had suspected or confirmed BOT malignancy. Controls were healthy individuals without known malignancy. RESULTS: 100% of BOT tumors were visualized. On ultrasound BOT tumors were hypoechoic (90.9%) with irregular margins (95.5%). Ultrasound could be used to characterize adjacent site involvement, midline extent, and endophytic extent, and visualize the lingual artery. No tumors were suspected for controls. CONCLUSIONS: Ultrasonography can be used to transcervically visualize BOT tumors and provides clinically relevant characteristics that may not otherwise be appreciable.

RESUMO

OBJECTIVE: To report a single institution's experience with transoral robotic surgery (TORS) and its clinical outcomes. This was a retrospective study carried out at a university-affiliated teaching hospital. SUBJECTS AND METHODS: Forty-four consecutive TORS patients with benign and malignant diseases were reviewed. Data on demographics, clinical parameters, and diet were collected. Surgical margins, local and regional recurrence, distant metastasis, 2-year disease-free survival rate, and 2-year survival data were reviewed for the malignant cases. RESULTS: Nine benign and 35 proven squamous cell carcinoma (SCCA) cases underwent TORS. The set-up time was 17.12 minutes (range, 10-40 minutes), and operative time was 53 minutes (range, 10-300 minutes). Average length of stay was 2.5 days. There were seven (6.8%) grade 3 surgical complications. Surgical infection rate was 2.3%. Benign cases were on a regular diet after TORS. Of the malignant cases, 94% were taking peroral diet immediately after the TORS procedure. There were no intraoperative complications and no 30-day postoperative mortalities. The mean follow-up time was 25.2 months (range, 16-38 months) for malignant disease. The SCCA sites were in the oropharynx (30/35), larynx (2/35), and unknown primary with neck metastasis (3/35). Unknown primary patients were excluded in the surgical margin analyses. Negative margins were achieved in 91% of cases. The local and regional recurrence rates were 6.3% (2/32) and 3.1% (1/32), respectively. Two patients (6.3%) developed distant metastasis. Oropharyngeal SCCA cases were reviewed, of which 23 were human papillomavirus (HPV)/p16 positive and 7 were HPV/p16 negative. The 2-year actual survival for HPV-positive and -negative patients was 96% (22/23) and 86% (6/7), respectively. The 2-year disease-free survival for HPV-positive and -negative cases was 91% (21/23) and 71.4% (5/7), respectively. All malignant cases that underwent TORS received postoperative adjuvant therapy. CONCLUSIONS: TORS is a safe procedure with minimal complications and acceptable clinical and functional outcomes.

RESUMO

OBJECTIVE AND STUDY DESIGN: To assess the feasibility of robotic-assisted skull base surgery, a preclincal cadaver study was conducted. MATERIALS AND METHODS: The feasibility study was subdivided into three phases: Phase 1 (surgical corridor) entailed a review of the surgical access, Phase 2 (instrument configuration) entailed arrangements of the robotic instrument (da Vinci(®) Surgical System; Intuitive Surgical, Sunnyvale, CA) in relation to the surgical corridor and applied to a skull model, and Phase 3 was robotic-assisted skull base cadaver dissection. RESULTS: Regarding the surgical corridor, the infratemporal area was accessed through a maxillary window, whereas the anterior skull base region was accessed through a combined single maxillary window and nasal corridor. Regarding instrument configuration, the camera was positioned above the two instrument arms, with both instrument arms angled at 30° to the camera axis with a flexed distal tip for the infratemporal skull base. For the anterior skull base, one of the robotic arms was inserted through the unilateral maxillary window, whereas the three-dimensional camera and the second arm were inserted through the nasal corridor. Regarding the robotic-assisted skull base cadaver dissection, we define the robotic set-up time in this study as the time required to move the robot into position, obtain adequate operative exposure, and place the robotic arms prior to the start of robotic dissection. The robotic set-up time for the anterior skull base dissection averaged 95 minutes, and that for pituitary resection was 61 minutes. The robotic set-up time for infratemporal dissection averaged 23 minutes. Operative time was 63.5 minutes. Robotic and endoscopic techniques can be combined during surgery. CONCLUSIONS: Robotic-assisted skull base surgery is feasible. The da Vinci instrument needs to be redesigned to be smaller and preferably with distal articulating tips, prior to clinical application of robotics to skull base surgery.

RESUMO

Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients.

RESUMO

The introduction of robotics in head and neck surgery has facilitated access to the contents of the neck region using less cosmetically obtrusive incisions. Robotic systems offer a three-dimensional viewing, tremor filtration, and articulating distal arms that mimic natural hand and wrist movements. We hypothesized that these characteristics would allow for the performance of a robotic-assisted selective and comprehensive neck dissection via combined pre- and post-auricular incisions. We were able to demonstrate adequate access in a cadaver, using a combination of conventional, endoscopic, and robotic surgical manipulation. Thus preclinical cadaver studies support the ability to perform robotic-assisted neck dissection via combined pre- and post-auricular incisions.

RESUMO

OBJECTIVES/HYPOTHESIS: To determine the feasibility and safety of neck dissection through a facelift incision. STUDY DESIGN: Prospective case series. METHODS: Cadavers and live subjects underwent neck dissection using a facelift incision with and without endoscopic assistance. In the live facelift neck dissection (FLND), the preoperative surgical indications, staging, adjuvant therapy, intraoperative technical procedure, pathology reports on lymph nodes, and short-term outcomes were reviewed. RESULTS: FLND was successfully performed in four cadavers and four live subjects, including selective (less than five neck levels removed) and comprehensive (levels I-V removed) neck dissections. All levels were accessible through this approach, with additional retraction required for levels I and IV. Endoscopic assistance was required in one neck dissection for adequate visualization. Short-term complications and number of excised lymph nodes were comparable to those from traditional neck dissection approaches. CONCLUSIONS: Open neck dissection through a facelift incision is feasible and offers an alternate approach to traditional incisions. This can be performed without requiring robotic assistance and with endoscopic assistance only in certain cases. Endoscopic assistance can offer enhanced visualization of the surgical field and complement open direct approaches in neck dissection. Although FLND offers improved cosmetic outcomes when compared to those of traditional neck incisions, further study is required to determine its efficacy and indications.
