Transoral robotic surgery (TORS) is an emerging technique for the treatment of head and neck tumors. The objective of this study is to describe our first steps and present our experience on the technical feasibility, safety, and efficacy of TORS for the treatment of selected malignant lesions. From April 2008 to September 2009, 24 patients were enrolled in this prospective trial. Inclusion criteria were: adults with T1, T2 and selected T3 tumors involving the oral cavity, pharynx, and supraglottic larynx and a signed informed consent was obtained from the patient. Exclusion criteria were: tumors not accessible to TORS after unsuccessful attempts to expose properly the lesion to operate. The ethical committee's approval was obtained to perform this study. Twenty-four patients were included in this study: 10 supraglottic tumors, 10 pharyngeal tumors and 4 oral cavity tumors. Nine patients had T1 tumors, 12 had T2 tumors, and 1 patient had a T3 tumor. In all cases, tumor resection could be performed by robotic surgery exclusively and negative resection margins were achieved with control by frozen section. None of them received intraoperative reconstruction. None of the patients required tracheotomy. There was no intraoperative complication related to the use of the robot. The average setup time was 24 ± 14 min (range 10-60 min). The average surgical time was 67 ± 46 min (range 12-180 min). Surgical and setup time decreased after the first cases. The mean hospital stay was 9 days. Oral feeding was resumed at 3 days. TORS seems to be a safe, feasible, minimally invasive treatment modality for malignant head and neck tumors with a short learning curve for surgeons already experienced in endoscopic surgery.
It is accepted that the follow-up of patients who had treatment for laryngeal cancer is a fundamental part of their care. The reasons of post-treatment follow-up include evaluation of treatment response, early identification of recurrence, early detection of new primary tumours, monitoring and management of complications, optimisation of rehabilitation, promotion smoking and excessive alcohol cessation, provision of support to patients and their families, patient counselling and education. Controversies exist in how these aims are achieved. Increasing efforts are being made to rationalise the structure and timing of head and neck cancer follow-up clinics. The aim of this document is to analyse the current evidence for the need to follow up patients who have been treated for LC and provide an up to date, evidence-based statement which is meaningful and applicable to all European Health Care Systems. A working group of the Head and Neck Cancer Committee of the ELS was constituted in 2009. A review of the current published literature on the management and follow-up of laryngeal cancer was undertaken and statements are made based on critical appraisal of the literature and best current evidence. Category recommendations were based on the Oxford Centre for Evidence-Based Medicine. Statements include: length, frequency, setting, type of health professional, clinical assessment, screening investigations, patient's education, second primary tumours, and mode of treatment considerations including radiotherapy, chemo-radiation therapy, transoral surgery and open surgery. It also addresses specific recommendations regarding patients with persistent pain, new imaging techniques, tumour markers and narrow band imaging.
Endoscopic resection of laryngeal tumors is replacing external approaches. One drawback of endoscopic resection is the difficulty of interpretation of histological specimens because of thermal effect of laser on tissues. Our goal is to assess the reliability of frozen section in this setting by comparing its results with those of routine histology. We, retrospectively, reviewed the charts of all consecutive patients, who underwent cordectomies in our institution between January 2000 and 2008, using the CO(2) laser Acublade system (Lumenis, Santa Clara, CA). Age, sex, staging of the tumor, previous treatments, type of cordectomy, frozen section and routine histology results were analyzed. Ninety-seven patients fulfilled the inclusion criteria; 22.7% had severe dysplasia, 54.6% had T1 epidermoid carcinoma, 17.5% had T2 carcinoma and finally 5.2% had T3 carcinoma. We performed type I cordectomy in 36.1% of patients, type II cordectomy in 18.6%, type III cordectomy in 10.3%, type IV cordectomy in 5.2%, type V cordectomy in 28.9% and type VI cordectomy in 1% of patients. Most of the patients did not have any previous treatment. The mean number of margins per surgery was 2. Routine histological examination confirmed frozen section in 94.8% of the interventions. Frozen section is reliable in laser-assisted cordectomies, when performed by an experienced team; it has a high negative-predictive value. It can limit the need, cost and emotional stress of second look surgeries.
The prognosis of cancer patients is highly dependent on the time of diagnosis. Early, stage 1 disease is often curable whereas late stage diseases are usually beyond curable treatments. Therefore, new diagnostic tools for malignancies of the upper aerodigestive tract are developed all the time and narrow band imaging (NBI) is one of these new options for early diagnostics. In this paper, we describe the implementation of NBI technique in our institution. During the first 6 weeks we used NBI to examine 73 patients with different types of pharyngeal or laryngeal problems. Most of the patients (77%) were on follow-up visits after earlier malignant disease. In our series we had 11 NBI-positive patients and the histological diagnosis was carcinoma or dysplasia among 10 of these. Among the NBI negative patients we found four carcinomas. It is notable that NBI affected the decision of a biopsy procedure in three patients, with final diagnosis of dysplasia or carcinoma. In conclusion, we find NBI useful in the diagnostics of malignancies of the upper aerodigestive tract. This is a useful tool in improving the accuracy of the diagnostics. However, it still takes an experienced clinician and a learning curve can be expected.
Background: Laryngotracheal stenosis is difficult to treat and its etiologies are multiple; nowadays, the most common ones are postintubation or posttracheostomy stenoses. Objective: To provide an algorithm for the management of postintubation laryngotracheal stenoses (PILTS) based on the experience of a tertiary care referral center. Methods: A retrospective study was conducted on all patients treated for PILTS over a 10-year period. Patients were divided into a surgically and an endoscopically treated group according to predefined criteria. The characteristics of the two groups were analyzed and the outcomes compared. Results: Thirty-three consecutive patients were included in the study: 14 in the surgically treated group and 19 in the endoscopically treated group. Our candidates for airway surgery were healthy patients presenting with complex tracheal stenoses, subglottic involvement or associated tracheomalacia. The endoscopic candidates were chronically ill patients presenting with simple, strictly tracheal stenoses not exceeding 4 cm in length. Stents were placed if the stenosis was associated with tracheomalacia or exceeded 2 cm in total length. In the surgically treated group, 2/14 patients needed more than one procedure versus 8/19 patients in the endoscopically treated group. At the end of the intervention, 50% of the patients were decannulated in the surgically treated group versus 84.2% in the endoscopically treated group (p = 0.03). However, the decannulation rates at 6 months and the symptomatology at rest and on exertion on the last follow-up visit were comparable in the two groups. Conclusion: Our experience in the management of PILTS demonstrates that both surgery and endoscopy yield excellent functional outcomes if the treatment strategy is based on clear, predefined objective criteria.
SNT is reliable in the staging of the clinically N0 neck in patients with supraglottic cancer.
