Total Remission

The favorable results obtained by other authors with polichemotherapy encouraged us to employ therapeutic scheme using a combination of 4 drugs. Treatment envolved the administration of 300 mg/m2 cyclophosphamide, 350 mg/m2 5-fluorouracil, 10 mg/m2 methotrexate i.v. on alternate days 6–8 times, and 15 mg bleomycin on alternate days until a total dose of 150–200 mg is reached. Thirty-five out of 37 patients treated with this protocol (30 previously treated and 5 not) qualified for analysis; the site of the neoplasm, mostly squamous cell carcinoma, was different; for the most part it was in the larynx (18/35) and the oral cavity (10/35). Complete remission was achieved in 9/35 patients (25.7%), varying from 5 to 33 months (median 22); partial remission was achieved in 15/35 cases (42.8%), varying from 1 to 14 months (median 3); and there was no success in 11/35 cases (31.5%). Overall, a total remission > 50 % was observed in 24/35 patients (68.5 %). The most serious side effects both ascribed to BLM were observed in the central nervous system (increasing drowsiness and coma) and the lung. This study has shown that in the ultra head and neck malignancies medical treatment can achieve satisfactory results.

The Central Nervous System

Extracranial meningiomas have been reported for decades now and have been described in the head and neck; calvarial, nasal cavity, paranasal sinuses, nasopharynx, parotid gland and in various remote anatomical locations systemically. The presence of microanatomical structures for all intents and purposes resembling and having the histopathological characteristics of meninges outside of the central nervous system meninges is uncommon but well-documented. Typically, these lesions are found in the lung or part of hamartomatous/choristomatous lesions and frequently occur in the head and neck anatomical region. The lesion first described by Suster and Rosai termed \"hamartoma of the scalp with ectopic meningothelial elements\" is the prototypical example of lesions with meningothelial elements. We have described recently a similar hamartomatous lesion with meningothelial elements occurring in the tongue. In this chapter, we will review the clinicopathological features of ectopic meningiomas and lesions that contain meningothelial elements and their possible pathogenesis.

Primitive neuroectodermal tumors (PNETs) are extremely rare tumors. These neoplasms can occur at sites outside of the central nervous system. The head and neck location is unsual. We report a case with primitive neuroectodermal tumor (PNET) of the parotid. We analyze through this observation the clinical, histological and therapeutic characteristics of this entity.

Early diagnosis, along with innovative treatment options, are crucial to increase the overall survival of cancer patients. In the last decade, extracellular vesicles (EVs) have gained great interest in biomarker discovery. EVs are bilayer lipid membrane limited structures, released by almost all cell types, including cancer cells. The EV cargo, which consists of RNAs, proteins, DNA, and lipids, directly mirrors the cells of origin. EVs can be recovered from several body fluids, including blood, cerebral spinal fluid (CSF), saliva, and Broncho-Alveolar Lavage Fluid (BALF), by non-invasive or minimally invasive approaches, and are therefore proposed as feasible cancer diagnostic tools. In this review, methodologies for EV isolation and characterization and their impact as diagnostics for the central nervous system, head and neck, lung, and gastrointestinal cancers are outlined. For each of these tumours, recent data on the potential clinical applications of the EV’s unique cargo, alone or in combination with currently available tumour biomarkers, have been deeply discussed.
