RESUMEN
BACKGROUND: There are delays in the head and neck Urgent Suspicion of Cancer (USOC) pathway. Local anesthetic (LA) biopsy with channeled endoscopes in outpatients can reduce time to diagnosis. METHODS: Questionnaire-based prospective study of LA or general anesthetic (GA) biopsy for investigation of cancer from September 2021 to July 2022. RESULTS: 100% (n = 48) were very satisfied or satisfied with their overall experience. 71% (n = 20) of LA patients reported they would prefer to have a biopsy under LA. LA biopsy was 68% sensitive and 100% specific for cancer diagnosis. 28.6% (8) and 10% (2) of LA and GA patients had palliative MDT outcomes. Median time to diagnosis was 44.5 and 49.0 days for LA and GA biopsy, respectively. CONCLUSION: LA biopsy had a high satisfaction rate and is sensitive for diagnosing cancer. LA biopsy can expedite treatment pathways. LA biopsy should be considered as an option for first line investigation.

PURPOSE: To evaluate the utility of various pre-treatment prognostic scoring systems for overall survival (OS) in laryngeal cancer, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), modified Glasgow Prognostic Score (mGPS) and systemic immune-inflammatory index (SIII). METHODS: We undertook a retrospective 5-year study of 220 patients with laryngeal squamous cell carcinoma undergoing active treatment. RESULTS: On multivariate analysis, low NLR (≤ 2.415, p = 0.001, OR 3.851), low PLR (≤ 269.855, p = 0.002, OR 5.520), high LMR (> 2.225, p < 0.001, OR 0.458) and low SIII (≤ 1144.465, p = 0.003, OR 3.673) were significantly associated with improved OS, accounting for confounding factors of tumour subsite, T-stage and performance status. C-reactive protein (CRP) alone (p = 0.264) and mGPS (p = 0.350) were not significantly associated with OS. CONCLUSIONS: NLR, PLR, LMR and SIII represent inexpensive, easily obtainable adjuvant decision-making tools which could help tailor individualised treatment regimes. Further investigation into the utility of combination scores and the role of different laryngeal subsites may be of interest.

BACKGROUND: In-office biopsies (IOB) using local anaesthetic for laryngopharyngeal tumours has become an increasingly popular approach since the advent of distal chip endoscopes. Although a wide range of studies advocate use in clinical practice, the widespread application of the procedure is hampered by concerns regarding diagnostic accuracy. OBJECTIVE: To assess the diagnostic accuracy of IOB performed via flexible endoscopy. In addition, to analyse modifiable factors that may affect diagnostic accuracy of IOB. DESIGN: A systematic review following the PRISMA guidelines was conducted. PubMed, EMBASE, the Cochrane Library, Web of Science and CINAHL were used in the literature database search. Quality assessment of included studies was perfomed using the Newcastle-Ottawa Scale. RESULTS: A total of 875 studies were identified, 16 of which were included into the systematic review; 1572 successful biopsies were performed using flexible endoscopy; 1283 cases were accurately diagnosed in the outpatient setting (81.6%) and 289 samples did not provide an accurate diagnosis (18.4%). The median sensitivity of IOB was 73%, and the specificity was 96.7%. Analysis of variable factors did not show any significant differences in method of approach, size of equipment (forceps) and additional lighting system or learning curve. CONCLUSION: IOB are a viable tool for diagnostic workup of laryngopharyngeal tumours. Clinicians should be wary of reported limitations of IOB when benign or pre-malignant diagnoses are made. In cases suspicious of malignancy, confirmatory investigation should be conducted.
