How effective is our current follow-up for patients with hypopharyngeal carcinoma?

BACKGROUND: The study aimed to evaluate the diagnostic efficacy of routine follow-up in detecting recurrent disease in hypopharyngeal carcinoma. METHODS: Data from 76 patients with a total of 620 follow-up visits, 367 radiological studies, and 126 panendoscopies were retrospectively assessed regarding the diagnosis of recurrent disease based on the results of (I) radiological studies, (II) clinical examinations, and (III) clinical symptoms. RESULTS: All locally relapsed patients became symptomatic, and new onset of dysphagia (p < 0.001) was the most frequent complaint. The sensitivity for detecting local recurrences was 100% for both patients' symptom assessments and clinical examinations. The highest overall accuracy was found for clinical examinations (93.4%), followed by symptom assessments (80.5%), and radiological studies (73.8%). The risk of false positive radiological reports and subsequent panendoscopies was 2.2 times higher after previous radiotherapy (32.0% vs. 14.6%; p < 0.001). CONCLUSION: Symptom assessments and clinical examinations are highly efficient for detection of local failures.

Endoscopic-assisted transorbital extended orbital exenteration: A multi-institutional preclinical study.

BACKGROUND: Sinonasal malignancies with orbital invasion have dismal prognosis even when treated with orbital exenteration (OE). Sugawara et al. developed a surgical strategy called "extended-OE (EOE)," showing encouraging outcomes. We hypothesized that a similar resection is achievable under endoscopic guidance through the exenterated orbit (endoscopic-EOE). METHODS: The study was conducted in three institutions: University of Vienna; Mayo Clinic; University of Insubria; 48 orbital dissections were performed. A questionnaire was developed to evaluate feasibility and safety of each step, scoring from 1 to 10, ("impossible" to "easy," and "high risk" to "low risk," respectively), most likely complication(s) were hypothesized. RESULTS: The step-by-step technique is thoroughly described. The questionnaire was answered by 25 anterior skull base surgeons from six countries. Mean, median, range, and interquartile range of both feasibility and safety scores are reported. CONCLUSIONS: Endoscopic-EOE is a challenging but feasible procedure. Clinical validation is required to assess real-life outcomes.

Neurological Complications in Benign Parapharyngeal Space Tumors - Systematic Review and Meta-Analysis

Abstract Introduction Parapharyngeal space tumors with complex anatomy and diverse histology have remained a challenging phenomenon for treating physicians. Objectives We have conducted a comprehensive web search on the PubMed, Web of Science, EMBASE, Cochrane Library, Biomedical Literature Database (CBM), and Clinicaltrials.gov databases to determine the factors that are associated with postoperative complications in parapharyngeal space tumors. Data Synthesis Two researchers reviewed all identified articles independently with a third reviewer for adjudication. Patient demographics and other clinicopathological characteristics were explored. The systematic review has identified 631 benign parapharyngeal space tumors with neurogenic and salivary tissue histology in 13 studies, with a mean age of 42.9 ± 7.76 years old and a median follow-up of 40.98 ± 19.1 months. Salivary gland (50.8%) and neurogenic (49.1%) tumors were the most common histological entities. Tumor size, location, histology, deep parotid lobe involvement, and proximity to great vessels or to the skull base were the deciding factors in selecting the surgical approach. The factors considered to select the surgical approach do not seem to have a correlation with the outcome in terms of neurological sequalae (p = 0.106). Tumors with neurogenic histology have significantly increased chances of developing neurological complication (OR 6.07; p = 0.001). Conclusion Neurologic complications are significantly associated with neurogenic benign tumors rather than surgical approach.

Survival Outcome in True Carcinoma of Unknown Primary (tCUP) with p16 + Cervical Metastasis

Abstract Introduction Age and lymph node ratio have been attributed as independent predictors for survival and recurrence in carcinoma of unknown primary (CUP). Objective The purpose of this study was to analyze the prognostic value of p16 overexpression for CUP in the absence of true primary (TP). Methods The study involved 43 patients who underwent therapeutic lymph node dissection (LND) from 2000 to 2015 after all the diagnostic work up for CUP. Immunohistochemistry for p16 overexpression was performed. Cox proportional hazard regression analysis was used to analyze the prognostic impact on 5-year overall survival (OS) and recurrence-free survival (RFS). Results The male-to-female ratio was 5.1:1, with a median age of 62 years. The clinicopathological data, except for p16 overexpression, did not differ significantly in terms of 5-year OS and RFS. The Cox regression analysis proposed p16 positivity to be an independent prognosticator of regional recurrence-free survival (RRFS) (hazard ratio [HR] 6.180, p = 0.21). The median time to recurrence and death were 10 and 25 months, respectively. Conclusion Cervical metastasis with p16 overexpression is a significant prognostic factor of improved RFS after surgery in CUP. The prognostic significance of lymph node p16 positivity should be further studied.
