Role of imaging in the follow-up of T2-T3 glottic cancer treated by transoral laser microsurgery.

An unblinded retrospective analysis of prospectively collected data was carried out on 138 patients affected by glottic pT2 and selected pT3 squamous cell carcinomas (SCC) treated by transoral laser microsurgery (TLM). The entire cohort was divided into two groups: Group A included 78 "high-risk" patients (pT2 with impaired vocal cord mobility, pT3 for anterior paraglottic and/or pre-epiglottic space invasion, presence of angioembolization, perineural spread, and positive lymph nodes in the neck) who underwent postoperative surveillance by endoscopy and imaging (CT or MR), while Group B included 60 "low-risk" patients (pT2 with absence of the above-mentioned features) who underwent endoscopic follow-up alone. Aim of the present study was to assess the diagnostic gain in performing combined endoscopic and radiologic surveillance in the "high-risk" group compared to endoscopy alone in the "low-risk" one. There was no significant difference in terms of overall and disease-specific survivals between the two follow-up policies in spite of their different risk profiles. The same was true for organ preservation rate, which was 81% in the "high-risk" and 89% in the "low-risk" group. In contrast, the cumulative probability of disease-free survival was 54% for Group A and 65% for Group B (p = 0.0023). Therefore, our combined endoscopy and imaging surveillance protocol allowed increasing the submucosal recurrence detection rate in "high-risk" pT2-pT3 glottic SCC to 43%. An earlier detection of submucosal recurrences made salvage surgery by TLM feasible in at least half of cases, thus closing the gap between oncologic outcomes obtained in "high-"- vs. "low-risk" patients and leading to organ preservation rates that are favorably comparable to those obtained with open-neck partial laryngectomies and non-surgical organ preservation protocols.

Functional outcomes after different types of transoral supraglottic laryngectomy.

OBJECTIVES/HYPOTHESIS: To seek a correlation between the four types of transoral supraglottic laryngectomies (TSLs) according to the European Laryngological Society (ELS) and postoperative morbidity. STUDY DESIGN: Retrospective case series at an academic institution. METHODS: Chart review was done for 96 patients affected by T1-T3 supraglottic cancers (28 pT1, 46 pT2, 22 pT3) treated by TSL (29 type I, 14 type II, 35 type III, 18 type IV) with CO2 laser. Five-year overall survival (OS), disease-specific survival (DSS), local control with laser alone (LCL), and organ preservation (OP) were calculated by Kaplan-Meier curves. Thirty-six patients were submitted to swallowing evaluation by M. D. Anderson Dysphagia Inventory (MDADI), videoendoscopy of swallow (VEES), and videofluoroscopy (VFS). Hospitalization, tracheotomy, nasogastric feeding tube (NGFT), and complications were compared between type I-II versus III-IV TSLs for the entire series. MDADI and VEES/VFS scores were compared in the subgroup of 36 patients. RESULTS: Five-year OS, DSS, LCL, and OP rates were 69%, 85.9%, 89.2%, and 92.6%. Mean hospitalization was 9 days, tracheotomy was required in 7% of patients, an NGFT was required in 33%, and 11% experienced complications. Type III-IV TSLs were associated with increased hospitalization (P < .001), more NGFTs (P = .001), and 90% of complications (P = .021). Aspiration was seen in 0% and 9% of type I-II TSLs, and in 7% and 43% of type III-IV TSLs by VEES and VFS, respectively. CONCLUSIONS: Type III-IV TSLs present higher morbidity and complications, thus confirming the utility of the ELS classification in preoperative counseling and therapeutic planning.

Nasal tactile sensitivity in allergic rhinitis.

CONCLUSION: These preliminary data show a decrease in nasal tactile sensitivity and point out interesting aspects of the nasal chronic inflammatory condition in allergic rhinitis. OBJECTIVES: The aim of this study was to evaluate the effects of allergic rhinitis on nasal tactile sensitivity during the intercritical period. METHODS: A total of 70 patients aged between 18 and 67 years (average 42 years), with a positive history of allergy caused by seasonal outdoor allergens, were included (group A). Patient outcome was assessed by the nasal monofilament test: a set of 20 Semmes-Weinstein monofilaments was used to detect nasal sensitivity for both nasal cavities. The sensitivity threshold was recorded as the minimum monofilament size with which patients could detect at least two of three stimuli. RESULTS: When compared to the control group (group B), subjects in group A required a significantly (p < 0.05) higher stimulus to trigger a touch response in the monofilament test, for both the inferior (195.1 ± 0.39 mg vs 67.7 ± 0.19 mg) and middle turbinate (108.7 ± 0.23 mg vs 67.7 ± 0.19 mg).
