“…Leukoplakia, in contrast to erythroplasia, tends to be well demarcated. In general, leukoplakia has a lower risk of malignant transformation than mixed white and red lesions, or speckled leukoplakia, which has an intermediate risk, and pure erythroplasia which has the highest risk of cancer development (64). However, no one clinical appearance is reliably diagnostic of any histologic grade of precursor lesion.…”

Abstract.Background: Multi-step cancerogenesis guides laryngeal cancer onset and it includes a wide variety of pre-cancerous lesions that are macroscopically challenging to identify and distinguish from initial cancerous foci. Since the treatment of laryngeal cancer and its precursor lesions has a great impact on important laryngeal basic functions, early detection and preoperative assessment are important for a curative and function-preserving therapy. Nowadays, despite the high number of more advanced diagnostic techniques and methods, unfortunately, it is not uncommon for different clinicians to use different nomenclature or to identify different stage for the same laryngeal lesion. From these observations, it is obvious that an instrument offering the possibility to detect precancerous lesions, early cancerous lesions, and satellite foci or second primaries would be the key to improving management and outcome in laryngeal patients. Object. Different modalities of diagnostic techniques of laryngeal lesions exist. Rather than difference between benign and obvious malignant diseases, more difficult is to detect the presence of precancerous epithelial alterations. Not all tests achieve the same diagnostic accuracy, hence this meta-analysis of literature aimed to synthesize the validity of each single diagnostic technique in identifying and staging laryngeal disease. Methods: A systematic review of literature was led searching for articles mentioning the following terms including their various combinations to maximize the yield: larynx, laryngeal precancerous lesions, laryngeal cancer, white light (WL) endoscopy, stroboscopy, contact endoscopy (CE), autofluorescence (AF), ultrasound (US), narrow band imaging (NBI), computed axial tomography (CAT), magnetic resonance imaging (MRI), positron emission tomography (PET), CAT/PET. Then, a quantitative analysis was carried on for paper published after 2005 onward, reporting a minumun series of 10 patients each study, declaring sensitivity and specificity of each diagnostic system. Results: The search identified 7215 publications, of which 3616 published after 2005, with a final results of a total of 214 articles stratified and included by our selection criteria. 42 out of 214 articles were selected for quantitative synthesis. 25 out of 41 studies had a quality score of ≥ 6 (good), 16 presented a score between 4 and 5 (fair). While objections can be raised about the pooling of different diagnostic procedures under the same group and the high level of heterogeneity in the meta-analyses, the inclusion of over 4400 laryngeal lesions makes the results fairly robust. Conclusions: A comprehensive overview of the most recent advances in laryngeal imaging technology combined with all of the information needed to interpret findings and successfully manage patients with voice disorders can be found herein. With these data, clinicians can riskstratify patients and select proper examination modalities in order to provide appropriate care. Moreover, study limitations, together with p...

Abstract. The present study reports the case of a 53-year-old man with leptomeningeal metastasis from early glottic laryngeal cancer. The patient had been diagnosed with squamous cell carcinoma of the glottic larynx 9 years previously. The current symptoms included a recurring headache that had persisted for 1 month and vomiting for 1 week. A magnetic resonance imaging scan of the head revealed multiple enhancing lesions in the brain and multiple line-like enhancements in the brain fold. Computed tomography scans of the head, neck, chest and abdomen showed no nodular lesions. Cytological examination of the cerebral spinal fluid (CSF) revealed malignant cells with a scattered distribution pattern. The patient received intra-CSF methotrexate chemotherapy concurrent with whole-brain radiotherapy, which relieved the neurological symptoms. To the best of our knowledge, this is the first case of cytologically-confirmed LM from early glottic laryngeal cancer.
