Long-term functional outcomes in tumour stage T2 glottic carcinoma after radiotherapy.

OBJECTIVE: To evaluate the long-term functional outcomes in patients who received primary radiotherapy for tumour-node stage T2N0 glottic carcinoma, stratified for tumour extension. METHODS: A cross-sectional study was performed on patients who were treated with radiotherapy for T2N0 glottic carcinoma. Four questionnaires were used to measure different aspects of functional outcome. In addition, objective evaluation and perceptual analysis were performed. RESULTS: Fourteen patients were included in this study. The median time between the start of radiotherapy and assessment was 42 months (range, 26-143 months). Patients reported high-level functioning, with low symptom scores and good swallowing function, and showed a median dysphonia grade of 1.5. The median Voice Handicap Index-30 score was 17.5. CONCLUSION: Patients with T2N0 glottic carcinoma treated with radiotherapy had good long-term quality of life, with low symptom scores, good swallowing functioning and slightly elevated voice outcome parameters.

CT findings of the temporal bone in CHARGE syndrome: aspects of importance in cochlear implant surgery.

To provide an overview of anomalies of the temporal bone in CHARGE syndrome relevant to cochlear implantation (CI), anatomical structures of the temporal bone and the respective genotypes were analysed. In this retrospective study, 42 CTs of the temporal bone of 42 patients with CHARGE syndrome were reviewed in consensus by two head-and-neck radiologists and two otological surgeons. Anatomical structures of the temporal bone were evaluated and correlated with genetic data. Abnormalities that might affect CI surgery were seen, such as a vascular structure, a petrosquamosal sinus (13 %), an underdeveloped mastoid (8 %) and an aberrant course of the facial nerve crossing the round window (9 %) and/or the promontory (18 %). The appearance of the inner ear varied widely: in 77 % of patients all semicircular canals were absent and the cochlea varied from normal to hypoplastic. A stenotic cochlear aperture was observed in 37 %. The middle ear was often affected with a stenotic round (14 %) or oval window (71 %). More anomalies were observed in patients with truncating mutations than with non-truncating mutations. Temporal bone findings in CHARGE syndrome vary widely. Vascular variants, aberrant route of the facial nerve, an underdeveloped mastoid, aplasia of the semicircular canals, and stenotic round window may complicate cochlear implantation.

Measurement of head and neck paragangliomas: is volumetric analysis worth the effort? A method comparison study.

OBJECTIVES: The aim of this study was to assess the reproducibility of different measurement methods and define the most workable technique for measuring head and neck paragangliomas, to determine the best method for evaluating tumour growth. The evaluation of tumour growth is vital for a 'wait-and-scan' policy, a management strategy that became increasingly important. STUDY DESIGN: Method comparison study. SETTING AND PARTICIPANTS: Thirty tumours, including carotid body, vagal body, jugulotympanic tumours and conglomerates of multiple tumours, were measured in duplicate, using linear dimensions, manual area tracing and an automated segmentation method. MAIN OUTCOME MEASURES: Reproducibility was assessed using the Bland-Altman method. RESULTS: The smallest detectable difference using the linear dimension method was 11% for carotid body and 27% for vagal body tumours, compared with 17% and 20% for the manual area tracing method. Due to the irregular shape of paragangliomas in the temporal bone and conglomerates, the manual area tracing method showed better results in these tumours (26% and 8% versus 54% and 47%). The linear dimension method was significantly faster (median 4.27 versus 18.46 minutes, P < 0.001). The automatic segmentation method yielded smallest detectable differences between 39% and 75%, and although fast (2.19 ± 1.49 minutes), it failed technically. CONCLUSIONS: Due to a relatively good reproducibility, fast and easy application, we found the linear dimension method to be the most pragmatic approach for evaluation of growth of carotid and vagal body paragangliomas. For jugulotympanic tumours, the preferred method is manual area tracing. However, volumetric changes of these tumours may be of less clinical importance than changes in relation to surrounding anatomical structures.

Induction chemotherapy with docetaxel/cisplatin/5-fluorouracil followed by randomization to two cisplatin-based concomitant chemoradiotherapy schedules in patients with locally advanced head and neck cancer (CONDOR study) (Dutch Head and Neck Society 08-01): A randomized phase II study.

PURPOSE: To study the feasibility of induction chemotherapy added to concomitant cisplatin-based chemoradiotherapy (CRT) in patients with locally advanced head and neck cancer (LAHNC). PATIENTS AND METHODS: LAHNC patients were treated with 4 courses of docetaxel/cisplatin/5-fluorouracil (TPF) followed by randomization to either cisplatin 100 mg/m(2) with conventional radiotherapy (cis100 + RT) or cisplatin 40 mg/m(2) weekly with accelerated radiotherapy (cis40 + ART). Primary endpoint was feasibility, defined as receiving ≥ 90% of the scheduled total radiation dose. Based on power analysis 70 patients were needed. RESULTS: 65 patients were enrolled. The data safety monitoring board advised to prematurely terminate the study, because only 22% and 41% (32% in total) of the patients treated with cis100 + RT (n = 27) and cis40 + ART (n = 29) could receive the planned dose cisplatin during CRT, respectively, even though the primary endpoint was reached. Most common grade 3-4 toxicity was febrile neutropenia (18%) during TPF and dehydration (26% vs 14%), dysphagia (26% vs 24%) and mucositis (22% vs 57%) during cis100 + RT and cis40 + ART, respectively. For the patients treated with cis100 + RT and cis40 + ART, two years progression free survival and overall survival were 70% and 78% versus 72% and 79%, respectively. CONCLUSION: After TPF induction chemotherapy, cisplatin-containing CRT is not feasible in LAHNC patients, because the total planned cisplatin dose could only be administered in 32% of the patients due to toxicity. However, all but 2 patients received more than 90% of the planned radiotherapy. Clinical Trials Information: NCT00774319.

Otological aspects and surgical outcome in a consanguineous family with a novel ANKH gene mutation.

OBJECTIVES: To report the hearing impairment in a new autosomal recessive metabolic disorder due to a mutation in the ANKH gene and to report the outcomes of exploratory tympanotomy. STUDY DESIGN: Retrospective chart study. SETTING: Tertiary referral center. PATIENTS: One large consanguineous family was examined. Three patients underwent exploratory tympanotomy. INTERVENTION: Exploratory tympanotomies in three patients. MAIN OUTCOME MEASURES: Medical and otological histories; postoperative hearing outcomes. RESULTS: In the patients who received tympanotomies, a postoperative hearing gain of between 5 and 20 dB was noted, with a residual air-bone gap of between 6 and 35 dB (follow-up between 4 and 67 months). The sensorineural component of the hearing impairment varies greatly, between 4 and 23 dB, and this factor might also affect the final hearing outcome. CONCLUSIONS: Exploratory tympanotomy might improve the hearing outcome in patients with this syndrome and therefore surgery has a limited audiometric benefit in general. Based on anatomical findings, a congenital origin for the ossicular chain anomaly seems likely. It remains unclear whether the sensorineural component of the hearing impairment is progressive and this should be investigated further.
