Abstract
OBJECTIVES There is sufficient evidence for a causal association of sinonasal epithelial cancers (SNEC) only for exposure to wood and leather dusts, nickel compounds and employment in isopropyl alcohol production. The aim of this study was to assess whether other occupational hazards are associated with the risk of SNEC for the main histologic types, namely adenocarcinoma (AD) and squamous cell carcinoma (SCC). METHODS The study population included 375 incident SNEC cases collected from 1996 to 2014 (79% of all diagnosed SNEC) throughout the Piedmont region by the regional Sinonasal Cancer Registry, and 408 hospital controls. Exposure to 17 occupational agents was assigned through expert assessment based on interviews to the subjects on jobs held throughout their working life. The relationship of SNEC with ever and cumulative exposure to the hazards was assessed through unconditional logistic regression models adjusted for age, sex, area of residence, smoking habit, year of enrolment and coexposures. RESULTS AD was associated with both ever and cumulative exposure to wood dust, leather dust and organic solvents, and with cumulative exposure to textiles dusts. SCC risk was significantly increased by ever exposure to nickel, chromium and welding fumes, as well as by cumulative exposure to welding fumes, arsenic and organic solvents. A mixed group of other histological types was associated with both ever and cumulative exposure to wood dust and textile dusts. CONCLUSIONS The associations of SNEC with wood dust, leather dust and nickel were confirmed, while some new associations were observed for other hazards, which merit further investigation.

Abstract
The emergency caused by Covid-19 pandemic raised interest in studying lifestyles and comorbidities as important determinants of poor Covid-19 prognosis. Data on tobacco smoking, alcohol consumption and obesity are still limited, while no data are available on the role of e-cigarettes and heated tobacco products (HTP). To clarify the role of tobacco smoking and other lifestyle habits on COVID-19 severity and progression, we designed a longitudinal observational study titled COvid19 and SMOking in ITaly (COSMO-IT). About 30 Italian hospitals in North, Centre and South of Italy joined the study. Its main aims are: 1) to quantify the role of tobacco smoking and smoking cessation on the severity and progression of COVID-19 in hospitalized patients; 2) to compare smoking prevalence and severity of the disease in relation to smoking in hospitalized COVID-19 patients versus patients treated at home; 3) to quantify the association between other lifestyle factors, such as e-cigarette and HTP use, alcohol and obesity and the risk of unfavourable COVID-19 outcomes. Socio-demographic, lifestyle and medical history information will be gathered for around 3000 hospitalized and 700-1000 home-isolated, laboratory-confirmed, COVID-19 patients. Given the current absence of a vaccine against SARS-COV-2 and the lack of a specific treatment for COVID-19, prevention strategies are of extreme importance. This project, designed to highly contribute to the international scientific debate on the role of avoidable lifestyle habits on COVID-19 severity, will provide valuable epidemiological data in order to support important recommendations to prevent COVID-19 incidence, progression and mortality.

Abstract
Cigarette smoke releases several toxic chemicals and carcinogens including carbon monoxide (CO). This study examined the levels of exhaled CO in smokers switching to electronic cigarettes (e-Cigs) or a tobacco heating system (THS) and their level of compliance six months after switching. On the basis of their own preferences, 40 male smokers unwilling or unable to stop smoking were switched to e-Cigs or THSs for six months (20 subjects in each group). Nicotine addiction and levels of carbon monoxide in the exhaled breath (eCO) were measured at baseline (the latter also at six months). The Shapiro Wilk test, graphical methods, Student T test or Mann-Whitney test were used to assess the normal distribution of variables and differences between the two groups after six months. The two groups showed no difference at baseline, but a significant higher addiction score in smokers choosing THS. E-Cig and THS showed significant reduced levels of eCO (both %COHb and COppm) after six months, which were within the range of non-smoker status. Reduced levels of %COHb did not significantly differ between the two groups, whilst the THS group had a significantly lower reduction in levels of COppm vs the e-Cig group (p < 0.05). Both e-Cigs and THSs are capable of significantly reducing eCO at least in the medium term, hence constituting a viable tobacco harm reduction approach in smokers who are unwilling or unable to stop smoking.

Abstract
The production of leukocyte migration inhibition factor (LIF) from lymphocytes after stimulation with 3 M KCl soluble tumor and normal mucosa extracts was investigated in 30 patients with laryngeal carcinoma at different development stages and in 30 normal donors. The experiments were performed in heterologous and autologous systems. In heterologous systems 3 M KCl tumor extracts induced LIF production by heterologous lymphocytes from patients in 91 % of the cases, and normal mucosa extracts induced LIF production by heterologous lymphocytes from patients in 73 % of the cases and from normal donors in 90 % of the cases. In autologous systems 3 M KCl tumor extracts induced LIF production by autologous lymphocytes from the same patients in 65 % of the cases, whereas the normal laryngeal mucosa extracts induced LIF production by the same autologous lymphocytes in the 6 % of the cases. The high positivity percentage of the test in heterologous systems could be related to differences in the major histocompatibility complex. The 65 % test positivity in autologous systems using tumor extracts could be related to the presence of tumor associated antigens.

Abstract
Aims and background Undifferentiated carcinoma of the parotid gland is a poor-prognosis lesion. Results in unresectable lesions, treated with radiotherapy alone, are very disappointing. Methods Six patients with T3-4 N0-1 inoperable lesions were treated with conventional radiotherapy (64-70 Gy, 2 Gy per fraction 5 times a week) and concomitant cisplatin (100 mg/m2, days 1, 22 and 43). Four weeks after radiotherapy, adjuvant chemotherapy (cisplatin, 80 mg/m2, day 1, + VP16, 100 mg/m2, days 1, 3 and 5, q = 3 weeks, for 3 cycles) was given. Results A median dose of 66 Gy (range, 64-70 Gy) was delivered, and all patients recived 3 courses of cisplatin during radiotherapy. Five of 6 patients recived all three chemotherapeutic adjuvant courses. Two months after the end of treatment, 3 CR (50%), 2 PR (33%) and 1 NC (16%) was observed. Median CR and PR duration was 26+ and 10 months, respectively. Median overall survival was 18 months. No severe acute or late toxicity was observed. Conclusions Concomitant chemoradiotherapy followed by adjuvant chemotherapy in advanced unresectable undifferentiated parotid carcinoma is feasibile and well tolerated. The high percentage of long-lasting CR is encouraging.

Abstract
The specific tumor-induced LIF production in 30 laryngeal cancer patients has been investigated before and after the removal of adherent cells to evaluate the existence of a suppressor activity. LIF production, after challenging lymphocytes with 3 M KCl autologous tumor extracts, was significant in 16 patients and showed a further significant increase after removal of adherent cells. A conversion to significance when the adherent cells were removed was shown in 6 patients, with no previous significant LIF production. These data suggest the existence of a suppressor activity exerted by adherent cells on LIF production in laryngeal cancer patients.

Abstract
Undifferentiated nasopharyngeal carcinoma is a chemosensitive lesion, but its role in the management of local advanced disease is under investigation. Twenty-seven untreated stage IV undifferentiated nasopharyngeal carcinoma patients were treated with radiotherapy (median dose, 66.6 Gy, 1.8 Gy/day) and concomitant cisplatin (100 mg/m2 days 1, 22 and 43). After 4 weeks, patients received, every 4 weeks, 3 cycles with cisplatin (80 mg/m2 day 1) + 5-fluorouracil (1000 mg/m2/day continuous infusion for 96 h). After radiotherapy, we observed 74% complete responses and 26% partial responses; after adjuvant chemotherapy 96% had a complete and 4% a partial response. After a median follow-up of 36 months, 81% of the patients were alive (70% with no evidence of disease). Four-year overall and disease-free survival was 70% and 60%, respectively. Concomitant chemotherapy plus radiotherapy was well tolerated, whereas adjuvant chemotherapy was more toxic. Long-term results were significantly better than those observed with radiotherapy alone.

Abstract
The electronic cigarette (e-cig) has gained popularity as an aid in smoking cessation programs mainly because it maintains the gestures and rituals of tobacco smoking. However, it has been shown in inexperienced e-cig users that ineffective nicotine delivery can cause tobacco craving that could be responsible for unsuccessful smoking reduction/cessation. Moreover, the incorrect use of an e-cig could also led to potential nicotine overdosage and intoxication. Medically assisted training on the proper use of an e-cig plus behavioral support for tobacco dependence could be a pivotal step in avoiding both issues. We performed an eight-month pilot study of adult smokers who started e-cig use after receiving a multi-component medically assisted training program with monitoring of nicotine intake as a biomarker of correct e-cig use. Participants were tested during follow-up for breath carbon monoxide (CO), plasma cotinine and trans-3’-hydroxycotinine, and number of tobacco cigarettes smoked. At the end of the first, fourth, and eighth month of follow-up, 91.1, 73.5, and 76.5% of participants respectively were e-cig users (‘only e-cig’ and ‘dual users’). They showed no significant variation in plasma cotinine and trans-3’-hydroxycotinine with respect to the start of the study when they smoked only tobacco cigarettes, but a significant reduction in breath CO. The proposed medically assisted training program of e-cig use led to a successful nicotine intake, lack of typical cigarette craving and overdosage symptoms and a significant decrease in the biomarker of cigarette combustion products.

Abstract
BACKGROUND Nystagmus induced by vibrations (NIV), has been optimized by the present authors this last decade. The skull vibration-induced nystagmus test (SVINT) can be designated as a high-frequency global "vestibular Weber test" and can be considered as an office-based examination to detect vestibular asymmetry. The aim of this study is to define the tolerance of the SVINT as well as its comparison to the simplified caloric test of Veits (CTV) in normal workers during the pre-employment visit at the occupational medicine center. MATERIAL AND METHODS The vestibular function has been evaluated by the SVINT and the CTV in 87 healthy workers. The tolerance of the two procedures has been evaluated by a 4-items questionnaire (nausea, vomiting, sweating, asthenia). RESULTS The caloric test was normal in each worker. The SVINT was positive in one patient who had a partial unilateral vestibular dysfunction related to trauma. The mean duration of the procedure was 15 min for CTV and 1 min for SVINT. Side effects (nausea, vomiting, sweating, asthenia) were present in 50% of the workers following CTV and in only one patient after SVINT. The SVINT demonstrated significantly less side effects for each item (p < 0.0001). CONCLUSIONS SVINT is a valid, rapid, low-cost clinical screening test and does not cause patient discomfort. It is suggested that this test which explores vestibular high frequencies and is not modified by vestibular compensation is useful for the diagnostic screening of workers' vestibular dysfunction, when combined with other vestibular tests and complements the CTV.

Abstract
OBJECTIVES Sinonasal inverted papilloma (IP) is an uncommon benign tumour characterised by frequent recurrence and, in approximately 10% of cases, by neoplastic transformation. IP aetiology is unknown but human papillomavirus is detectable in about one quarter of tumours. As some occupational hazards have been reported to be possible risk factors for IP, the aim of this study was to assess risk for sinonasal IP associated with prior exposure to suspected occupational risk factors for sinonasal malignancies. METHODS Between 1996 and 2007, data on incident cases were collected from hospitals throughout the Piedmont region of Italy by the regional sinonasal cancer registry. A questionnaire on occupational history, completed by 127 cases and 337 hospital controls, was used to assign previous exposure to a list of 17 occupational hazards. The relationship between IP and cumulative exposure to these hazards was explored using unconditional logistic regression to statistically adjust for age, sex, area of residence, smoking and co-exposures. RESULTS The risk of IP was significantly increased for ever exposure to welding fumes (OR 2.14) and organic solvents (OR 2.11) after controlling for potential confounders. For organic solvents only, a significant association with continuous cumulative exposure and a significant trend in risk across ordered cumulative exposure categories was found. CONCLUSIONS The present study revealed a significant association and a significant dose-response relationship between occupational exposure to organic solvents and IP. The lack of a dose-response relationship for welding fumes suggests that the observed association with ever exposure should be interpreted with caution.

Abstract
In view of the use of solvents and consequently the number of exposed subjects, health surveillance should include instrumental exams to highlight at an early stage alterations of health resulting from exposure. We evaluated 40 workers with chronic exposure to low-level xylene, toluene, fluorene and anthracene, showing that vestibular system was altered in a fair percentage of cases, compared to a control group characterized by 40 workers of the same age not exposed to solvents. The two groups were simultaneously exposed to noise. It is concluded that occupational exposure to industrial organic solvents may lead to chronic alteration of the vestibular system with possible alterations also on work capacity even below the established limits. Second, an assessment of the vestibular system should be introduced in the health surveillance of workers exposed, in which, in our opinion, the mastoid vibration test is a diagnostic tool absolutely valid and simple to perform.

Abstract
PURPOSE Aim of this study was the clinical evaluation of carboplatin-taxol combination in a neoadjuvant and concomitant setting with conventional radiotherapy in loco-regionally advanced nasopharyngeal carcinoma (A-NPC). METHODS Thirty patients were treated with three cycles of carboplatin (AUC6) plus taxol (175 mg/m(2)) on day 1 every 3 weeks, followed by weekly carboplatin (AUC1) plus Taxol (60 mg/m2) and concomitant radiotherapy (70 Gy). RESULTS We observed the objective complete response rates of 33% (after chemotherapy) and 87% (after chemo-radiotherapy). Treatment tolerability and toxicity were controllable. Three- and five-year progression-free survival were 80 and 75%, respectively, and 3- and 5-year overall survival were 85 and 80% (follow-up 49.5 months). Five-year loco-regional control was 90.3%, and five-year distant metastases-free survival was 85%. CONCLUSIONS Neoadjuvant chemotherapy with such protocol represents a feasible, efficient treatment for patients with A-NPC, ensuring excellent loco-regional disease control and overall survival with low incidence of distant metastases.

Abstract
OBJECTIVES Sino-nasal cancer has been consistently associated with exposure to wood dust, leather dust, nickel and chromium compounds; for other occupational hazards, the findings are somewhat mixed. The aim of this study was to investigate the risk of sino-nasal epithelial cancer (SNEC) by histological type with prior exposure to suspected occupational risk factors and, in particular, those in metalworking. METHODS Between 1996 and 2000, incident cases were collected on a monthly basis from hospitals throughout the Piedmont region of Italy by the regional Sino-nasal Cancer Registry. A questionnaire on occupational history, completed by 113 cases and 336 hospital controls, was used to assign exposure to occupational hazards. The relationship between SNEC and cumulative exposure to these hazards was explored using unconditional logistic regression to statistically adjust for age, sex, smoking and co-exposures, allowing for a 10-year latency period. RESULTS The risk of adenocarcinoma was significantly increased with ever-exposure to wood dust (odds ratio; OR = 58.6), and to leather dust (OR = 32.8) and organic solvents (OR = 4.3) after controlling for wood dust, whereas ever-exposure to welding fumes (OR = 3.7) and arsenic (OR = 4.4) significantly increased the risk for squamous cell carcinoma. For each of these hazards, a significant increasing trend in risk across ordered cumulative exposure categories was found and, except for arsenic, a significantly increased risk with ever-exposure at low intensity. Treating cumulative exposure on a continuous scale, a significant effect of textile dusts was also observed for adenocarcinoma. For a mixed group of other histological types, a significant association was found with wood dust and organic solvents. CONCLUSIONS Some occupational risk factors for SNEC were confirmed, and dose-response relationships were observed for other hazards that merit further investigation. The high risk for adenocarcinoma with low-intensity exposure to wood dust lends support for a reduction in the occupational threshold value.

Abstract
Two uncommon cases of paragangliomas arising from the vagus nerve are described. The first patient underwent surgery for suspected carotid body tumour. In the second patient, computed tomography scan and digital angiography allowed a correct pre-operative diagnosis to be made. These cases confirm the prevalence of vagal paragangliomas in female sex and middle age, and the possibility of multiple similar tumours in the same patient. Histological benign features, absence of neurological symptoms, of local invasion or intracranial extension confirm the frequent benign behaviour of these neoplasms. Lack of catecholamine secretion confirms the low incidence of functioning tumours. Contrast computed tomography and digital angiography still remain the gold standard reliable instruments for diagnosis despite the success of magnetic resonance imaging, magnetic resonance angiography and octreotide scintigraphy to detect head and neck paragangliomas. A transcervical approach, without mandibulotomy, is suitable too for large tumours but complete removal, with sparing of involved segments of the vagus nerve, is rarely possible. Post-operative neurological morbidity is still an unsolved issue and, therefore, rehabilitation of deglutition and phonation is an integral part of management.

Abstract
BACKGROUND The cytologic diagnosis of extracardiac rhabdomyoma is frequently hampered by its rarity and resemblance to various tumors. In this regard, the infrequent occurrence has hindered its prompt and early recognition. It is also confused with other tumors because of similarities in clinical and cytologic presentations. CASE A submandibular rhabdomyoma occurred in an otherwise-healthy, 62-year-old man. The neoplasm was firstly diagnosed by fine needle aspiration cytology (FNAC. Complete local excision without radical surgery was performed. Histologic findings confirmed the cytologic diagnosis of adult rhabdomyoma. Treatment-related complications were minimal, and there was no evidence of recurrent disease 6 years later. CONCLUSION Helpful FNAC features and immunocytochemical results permitted an early diagnosis and spared the patient unnecessary radical surgery.

Abstract
The prognostic significance of microvessel density and proliferative activity of the neoplastic cells, evaluated respectively by CD31 and Ki-67 positivity, and immunohistochemical expression of vascular endothelial growth factor (VEGF) was retrospectively investigated in 105 cases of sinonasal carcinoma (80 surgical specimens and 25 biopsies). The most represented histologic types were intestinal-type adenocarcinoma found in 36 patients (34.3%), squamous cell carcinoma (SCC) in 34 (32.4%), mucinous adenocarcinoma (mainly made up of signet-ring cell patterns) in 15 (14.3%), and adenoid cystic carcinoma in 7 (6.7%). Microvessel density values (in vessels per square millimeter), VEGF, and Ki-67 were not dependent on histologic type but were rather correlated to the histologic grading in SCC. Clinical data were available for 92 (87.6%) of 105 patients, with minimum follow-up of 48 months. Most of the patients (81.5%) were at an advanced stage (T3-T4) at diagnosis. The values of all markers were correlated to tumor stage (P = .03). Multivariate analysis showed that both microvessel density and proliferative activity of the neoplastic cells were independent prognostic parameters (mortality hazard ratio, 1.33 and 1.60, respectively). Although VEGF expression was not correlated to prognosis on the whole series (P = .06), it was a powerful prognostic marker when the analysis was restricted to the group of SCCs (hazard ratio, 3.02; 90% confidence interval, 1.58-5.80). These results show that tumor neoangiogenesis, expressed by microvessel density, together with proliferative activity, is a pathologic marker with a strong prognostic impact in sinonasal carcinomas. Therefore, it may be a useful tool in this field so as to carry out therapeutic protocol planning, which may be further enhanced by the adoption of the more recent antiangiogenic molecules.

Abstract
BACKGROUND Tobacco smoke is a well-known source of toxic, mutagenic and carcinogenic agents. The aim of the present preliminary study was to investigate the effects of cigarette smoking on lymphoid and non-lymphoid tonsillar tissue. METHODS The study group consisted of 12 smoker and 10 non-smoker patients complaining recurrent tonsillitis. Clinical data, histological findings and scanning electron microscopic analyses were considered. To the best of our knowledge, such an approach has not been previously adopted in a similar experimental model. RESULTS Smoker patients showed a longer history of recurrent tonsillitis, difficulties in clinical management and evident morphostructural changes than non-smokers. CONCLUSIONS These preliminary results suggest a possible interference of cigarette smoking with the therapy response as well as a possible role of tobacco smoke in impairment of inflammatory response. Results are critically analysed and discussed. Literature data on this subject are reviewed.

Abstract
Patients with squamous cell carcinoma of the head and neck (HNSCC) after being treated radically remain at high risk for both recurrent and second primary tumours. 13-cis retinoic acid (13-cRA) was demonstrated to reverse pre-malignant lesions of the oral cavity and to reduce the incidence of second primary tumours in patients treated radically for HNSCC. Synergism between retinoids and interferon in tumoural cell lines have been demonstrated. Based on these data, the Italian Head and Neck Chemoprevention Study Group started a randomized chemoprevention study in patients radically treated for stage III and IV HNSCC. From February 1992 to January 1996, 267 patients were randomized: 126 were allocated to the control group, 126 were randomized to receive 13-cRA at a dose of 0.5 mg/kg per day per os and 15 patients have been assigned to the group of 13-cRA plus interferon alpha2a (IFN-alpha2a) at a dose of 3,000,000 UI 3 times a week (randomization in this arm interrupted due to administrative financial problems). The mean follow-up was 39 months. The 5-year actuarial survival was 58.9% for patients of the 13-cRA group and 57.2% for those of the control group (P=0.94). Among evaluable patients, disease progression was observed in 45 of 123 patients (36.6%) of the 13-cRA group and in 42 of 124 (33.9%) of the control group. The 5-year actuarial relapse-free survival was 48.9% for the 13-cRA group and 55.6% for the control group (P=0.62). Adverse effects, mostly of grade I were reported in 69.4% of treated patients (haematologic disorders, mucositis, conjunctivitis, cutaneous toxicity, hypertriglyceridemia and hypercholesterolemia). Only 5 patients (4.1%) reported grade III-IV toxicity. Low-dose of 13-cRA given for 1 year is ineffective as chemoprevention in patients with radically treated HNSCC.

Abstract
BACKGROUND Interleukin (IL)-18 is a potent immunomodulatory cytokine promoting TH-1 and cytotoxic immune responses through interferon (IFN)-gamma induction. The aim of this study was to investigate the production of IL-18 by squamous cell carcinoma of the head and neck (HNSCC). METHODS The expression of IL-18 was analyzed by reverse transcriptase-polymerase chain reaction, Western blot, and ELISA in untreated and 5-fluorouracil (5-FU)-treated HNSCC cell lines. Immunohistochemical analysis was performed on tumor specimens from 16 patients with primary invasive HNSCC. RESULTS We have demonstrated that HNSCC cell lines express IL-18 at the mRNA, as well as the protein, level. However, the IL-18 protein was expressed intracellularly and predominantly released as an unprocessed inactive 24-kDa form. After exposure to 5-FU, the processed form of IL-18 was detected in the supernatants of both HNSCC cell lines. CONCLUSIONS These results indicate that HNSCC cells are a potential source of IL-18 cytokine. The finding that the exposure to 5-FU can elicit its processing suggests a novel target for immunomodulatory intervention in patients with HNSCC.

Abstract
This study was aimed at evaluating the efficacy of beta-carotene in improving survival (S) and in disease-free survival (DFS) and reducing the incidence of second primary tumors (SPT) in patients with a radically treated stage I-II squamous head and neck tumors. Eligible patients were randomly allocated to receive beta-carotene (n=104) or no treatment (n=110). beta-carotene was administered at the dose of 75 mg/day for 3-month cycles within one month intercycle intervals for a 3-year period. The 3-year compliance to the beta-carotene was 68.7%. Only eight patients reported drug-related toxicity (7.8%). The median follow-up of all patients was 59 months. The median follow-up was 61 months (range 1-116 months) in the beta-carotene and 58 months (1-123 months) in the control group. The 10-year DFS was 75.7% for the patients in the beta-carotene and 74.3% for those in the control group (P=0.56). The 10-year S was 85.9% in the beta-carotene group and 80.9% in the control group (P=0.20). beta-carotene supplementation had no significant effect on the incidence of second primary tumors (RR=0.99; 95% C.I. 0.28-3.44). A statistically non-significant 40% reduction in the risk of death among subjects assigned to the beta-carotene compared to the controls was observed (RR=0.60; 95% C.I. 0.26-1.38). No increase in the death from cardiovascular diseases was observed among patients treated with beta-carotene. Our results might support the hypothesis that an adequate beta-carotene treatment could be potentially associated with a decreased risk of death in these patients.

Abstract
Surgery is the treatment of choice for major and minor salivary gland malignancies. Herein, the role of radiation and medical treatment in the multidisciplinary management of salivary gland tumours is discussed. Neutron irradiation and hyperfractionated external beam mega voltage irradiation improve local control. Combination of three dimensional conformal radiotherapy and intensive-modulated radiation therapy provide better local tumour delineation, better field design to encompass the tumour allowing dose escalation to target while sparing the surrounding normal tissue. Cisplatin-based chemotherapy provides a response rate > or = 45%, in a palliative setting. Concomitant chemo-radiotherapy could improve local control. Recent studies evaluated the expression of molecular targets in salivary gland carcinomas (c-kit = 53-90%, EGFR = 25-85%, c-erb-B2 = 11-58%, p53 = 11-67%, H ras = 18%); these targets are very important since new targeted drugs are now available. Anti-androgen therapy might have a role in the management of patients with ductal carcinoma. These new targeted drugs could be integrated with chemotherapy and radiotherapy in the treatment of locally advanced/metastatic salivary gland malignancies.

Abstract
The purpose of this study was to evaluate pharmacokinetic parameters, efficacy, and toxicity of a combination of docetaxel (DTX) and vinorelbine (VNB) in recurrent heavily pretreated squamous cell head and neck cancer. Twenty-nine patients previously treated with concomitant chemoradiotherapy (n = 14), surgery plus radiotherapy (n = 13), surgery+concomitant chemoradiotherapy (n = 1) and radiotherapy alone (n = 1) were enrolled; 9 patients had received 1 or more courses of palliative chemotherapy. Twenty-one patients had a local-regional recurrence, and 8 patients had metastases. The doses were 80 mg/m2 for DTX and 20 mg/m2 for VNB on day 1 every 21 days for a maximum of 6 cycles. Pharmacokinetic evaluations were performed on 24 patients; in a group of 12 patients, VNB administration immediately followed DTX infusion (schedule A), and in 12 patients VNB administration was immediately followed by DTX infusion (schedule B). Twenty-nine patients received a total of 137 cycles (median per patient, 5). Neutropenia was the most frequent and severe side effect (grade IV in 79%; grade III in 21%). Grade IV (7%) and III (14%) infections were observed in the first 12 patients; ciprofloxacin prophylaxis in the following 17 patients reduced the severe toxicity to 0%. The overall response rate was 49%, which included 3 of 29 complete responses (10%) and 11 of 29 partial responses (38%). Median complete and partial response durations were 20+ and 5.5 months, respectively. Overall median survival was 10 months (range, 2-30+). The mean values of area under the curve, mean residence time (MRT), and C(max) of VNB were significantly lower for schedule A than for schedule B. The mean values of VNB clearance were significantly higher for schedule A than for schedule B. Neutrophil count at the nadir was much lower for patients receiving schedule B. The DTX-VNB combination is effective in heavily pretreated patients with a short-lasting manageable toxicity. Pharmacokinetic evaluations suggested that the sequence DTX --> VNB is safer than the sequence VNB --> DTX.

Abstract
A case of Wegener's granulomatosis in a 59-year-old woman is reported. The disease first involved the parotid gland, the brain stem and the spinal cord, then running a rapidly progressive course as systemic pathology. Anti-neutrophil cytoplasmic antibody (cANCA) levels raised as renal failure set in. Renal biopsy confirmed the diagnosis of Wegener's granulomatosis and an appropriate therapy was adopted.

Abstract
BACKGROUND The term auditory disability (AD) means the presence of auditory symptoms due to hearing loss. Until now the audiometric threshold cut-off between the presence or absence of AD was not clear. OBJECTIVES In this study we attempted to define the value of audiometric threshold that could be considered as the limit between the presence or absence of weakness of auditory function, considered as the threshold as the 95th percentile of subjects that did not report AD. METHODS The study group consisted of 1641 males, 891 normally hearing and 750 affected by noise-induced hearing loss (NIHL) Each subject was submitted to a questionnaire specifically created in order to determine the presence of AD. RESULTS Statistical analysis confirmed the reliability of answers to items. AD was present in 577 subjects, not all affected by NIHL. Audiometric threshold and age correlated significatively with the degree of AD. CONCLUSIONS The results obtained allowed the audiometric threshold values to be determined at the 95th percentile of subjects who did not report AD, in relation to the average of frequencies normally used in hearing loss evaluation.

Abstract
The present work was performed to check the non-auditory effects of environmental noise on a homogeneous worker population. The study was performed on 200 workers (factory and office workers) in a metallurgical and mechanical company: each individual underwent thorough clinical-audiometric study and filled out a multiple-choice psycho-social-attitude questionnaire. Statistical analysis of the results obtained showed a significantly higher number of non-auditory effects in subjects exposed to noise vs. those not exposed. For all workers studied, this incidence increased proportionally with age and job seniority. Moreover, it was demonstrated that there is no direct correlation between non-auditory effects and chronic traumatic hearing loss. The limited number of cases examined, however, suggests a multi-center study in order to provide better clinical-scientific and statistical-epidemiological study of this complex question involving on-the-job noise.

Abstract
The aim of this study was to evaluate the role of angiogenesis in the progression of laryngeal squamous cell carcinoma (LSCC). We correlated disease-free survival with microvessel count (MC) in the hot spot areas of 97 randomly selected caucasian males with LSCC followed for 60 to 90 months after surgery with or without radiotherapy. The results obtained indicate that: a) MC higher than 130 microvessels/mm2 is a cut-off value that distinguished patients who relapsed during the follow up period; b) multivariated analysis indicates that MC (p < 0.00001) is an independent predictor of disease free-survival; c) multivariated analysis selectively done on cases with relapse demonstrates that MC correlates with the presence of metastasis (or/and M) with local relapse (T). We suggest that MC is useful in the assessment of prognosis in LSCC and probably will permit selection of patients that could benefit from anti-angiogenic therapy associated with chemotherapy and/or radiotherapy.

Abstract
Angiogenesis is required for the growth of solid tumors which, in avascular condition, are limited to 2-3 mm3 volume. The switch to the angiogenic phenotype allows new vessels to converge upon the tumor, growth to proceed at an exponential rate and metastasis diffusion. The evaluation of tumoral angiogenesis has been proposed to be an independent prognostic marker of behaviour of some solid tumors: it has been demonstrated that, in some types of carcinoma (breast, prostate, lung, etc...), an intense vascular proliferation correlates with the aggressiveness of the disease. However in malignant melanomas and colorectal carcinomas, there are conflicting results on the correlation between angiogenesis and the progression of the cancer. There are also conflicting data on the role of microvessels count (MC) in the management of head and neck cancer. Despite a large number of studies, at the present, there are not biological or molecular markers available to predict consistently the outcome of the patients with laryngeal squamous cell carcinoma (LSCC). In fact the prognosis of this tumor has been mainly based, up to now, on a number of clinico-pathological parameters, especially localization, tumor extent and nodal involvement. The aim of this study has been to compare MC inside LSCC with disease free survival, grading, pT, pN and pathological stage. We investigated the relevance of the number of microvessels in the peritumoral stroma of 68 LSCC (only Caucasian males, age 35-70 years), classified according to UICC/1987 randomly selected (33 classified in clinical stage I e II and 35 in clinical stage III-IV). All patients have been surgically treated and pN + cases have been also submitted to radiotherapy. The follow-up was 60-84 months. The vascular density was assessed according to Horak et Al. with an immunohistochemical method using JC70 monoclonal antibody (CD31; Dako, Astrup, Denmark). Univariate analysis showed that MC, pT, pN, Pathological Stage and grading were correlated with the disease-free survival. A MC < 120/mm2 was predictive for a high survival index; in contrast a MC > 150 mm2 were associated with relapse. Furthermore, multivariate analysis demonstrated that MC was the only independent predictor for the disease free survival. Our findings demonstrate that in LSCC, MC is the first measurable biological parameter which is significant for evaluating the disease free-survival. Therefore, MC in LSCC is crucial in the prognosis and in the choice of a more aggressive management of the disease, including the possible treatment with antiangiogenic compound.

Abstract
The paper analyzes the 8 KHz threshold in subjects with noise-induced hearing loss. The study group consisted of 315 subjects occupationally exposed to noise and suffering from acoustic trauma, which was considered as a mean threshold of more than 25 dB at 2, 3 and 4 KHz. The mean shape of audiograms was characterized by a neurosensory deficit which was more elevated at 4 and 6 KHz whereas the threshold at 8 KHz was better. However, this pattern was found in 60% of the cases whereas in the remaining 40% the threshold at 8 KHz was worse. Subjects with the most impaired audiometric threshold at 8 KHz were mainly older, although cases were found in a low percentage of younger subjects. The results demonstrate that in individual cases it is impossible, on the basis of the shape of the audiogram, to establish whether a hearing loss is due to noise or age.

Abstract
The aim of this study was to determine the relationship existing between auditory disability, according to WHO 1980, and pure tone audiometry threshold in noise induced hearing loss. Disability was evaluated on the basis of a questionnaire submitted to 286 subjects with acoustic trauma. Answers obtained were considered reliable on the basis of statistical analysis. Results showed that subjects with disability have an higher pure tone threshold than subjects without auditory disability. However it appears difficult to determine a precise threshold level ever which auditory disability may be considered present. The Authors suggest that this limit could be determined on the basis of pure tone threshold at the 10th centile of the group of subjects with disability or at the 90th centile of subjects without disability.

Abstract
The paper examines the different aspects of the diagnosis of noise induced hearing disability and handicap. In the author's opinion a diagnosis of this kind can be made only if both an occupational acoustic trauma and a hearing disability or handicap are present. An occupational acoustic trauma can be considered to be present if the subject works in a noisy environment, if there are no auditory diseases other than of occupational origin, and if the audiometric threshold is neurosensorial, bilateral, more elevated at the higher frequencies and higher than the threshold of subjects on the same age but not exposed to industrial noise. On the other hand, the authors deem that there is a loss of hearing function when hearing disability and handicap are present according to the WHO definition. An experimental model is proposed that will establish the presence of hearing disability and handicap.

Abstract
Altered expression of growth factors and growth factor receptors is frequently described in human tumors and human tumor cell lines. This further supports the hypothesis that oncogenesis is due to the subversion of mitogen-responsive pathways. The aim of this study was to investigate the expression of epidermal growth factor receptor (EGFR) and transforming growth factor alpha (TGF alpha) in 13 larynx carcinomas and 2 carcinomas of the oral cavity. We found receptor overexpression in 7 out of 15 tumors at mRNA and/or protein level but low expression in the majority of the normal adjacent tissues. TGF alpha was expressed only in 1 case, but no tyrosine kinase activity of the receptor was detected by antiphosphotyrosine antibody.

Abstract
Postoperative CT of the latero-cervical lymph nodes was carried out in 25 patients suffering from laryngeal cancer. The surgically removed lymph nodes themselves were measured and examined histologically. 529/621 removed lymph nodes (about 85%) were recognisable with CT. The metastasized lymph nodes were clearly identified because of the presence of hypodense, poorly vascularised central foci. Some lymph nodes with a diameter of more than 15 mm on CT investigation proved free from metastatic lesions. This criterion should therefore be considered inadequate for diagnostic purposes. The CT cannot be held to be sufficiently precise to avoid conservative functional latero-cervical emptying as it is probably not able to recognise metastases without capsular rupture, not present in this series.

Abstract
The role of lymphokines in modulating the immune response in patients suffering from neoplastic disease is still controversial. Recent studies indicate that in patients with head and neck cancer, a decrease in LIF (leukocyte migration inhibiting factor) production is usually present in advanced disease. In this study, the authors investigate: the LIF production in lymphocytes derived from the peripheral blood and cervical nodes of patients with laryngeal carcinoma by using an autologous pattern (i.e., for each patient, the specific LIF production was challenged by means of an autologous cell extract derived from his own tumor); the influence of histologically confirmed cervical node metastases on LIF production. Our results indicate that: There is a significant decrease in LIF production in patients with histologically proven cervical node metastases as compared to patients with no metastatic foci. The decrease of LIF production is related to the presence of mononuclear adherent cells. When the latter are removed, there is a significant reversal of specific LIF suppression. The possible meaning of the data is discussed.

Abstract
The authors report preliminary data about IF-gamma (Interferon-gamma) basal serum production tested by monoclonal antibody in three groups of 25 patients: alpha (normal controls), beta (ragweed hayfever patients) and gamma (laryngeal carcinoma patients pT3-4, pN0----3, pM0 by UICC). The IF-gamma mean value in ragweed hayfever patients is about five times higher then normal controls. These data are highly statistically significative. Moreover no value of IF-gamma basal serum production is tested in laryngeal carcinoma patients. The data are discussed.

Abstract
The specific tumor-induced leukocyte inhibition factor (LIF) production in laryngeal cancer patients has been investigated before and after the removal of adherent cells in order to evaluate the existence of a suppressor activity; 20 patients served as subject. The LIF production, after challenging the lymphocytes with 3MKC1 autologous tumor extracts, was significant in 12 patients and showed a further significant increase after the removal of adherent cells. In 3 patients with no previous significant LIF production, there was a conversion to significance when the adherent cells were removed. The other patients did not show any significant variation. These data seem to suggest the existence of a suppressor activity exerted by adherent cells in laryngeal cancer patients on LIF production.

Abstract
We have evaluated in 80 patients suffering with laryngeal carcinoma their specific and aspecific immune responsiveness. We used the E rosette-test, the PHA-induced in vitro stimulation and the in vitro specific LIF production. We chose to use the LIF production test both for its marked sensitivity and because the lymphokines--which are soluble mediators--act as a "bridge" between the different fields of the immune response. Furthermore in our previous research, we observed that the specific LIF production was influenced in a negative way by adherent cells of the peripheral blood that could behave as blocking factors. For what attains the autologous LIF production, before and after the removal of adherent cells, our results show that the patients suffering with a cancer staged as T3T4N1N2N3 exhibit much more marked blocking phenomena than the patients with a cancer staged as T1T2T3N0. In fact the results demonstrate that in this second group only 62% of the cases, after the removal of the adherent cells, showed an increase of LIF production, while this percentage rose to 83% for the patients with a more advanced disease. A similar pattern was found in those patients who showed a recurrence two of three years after the primary disease.

Abstract
Since the T-suppressor subpopulation is known to have a peculiar sensitivity to the mitogenic activity of Concanavalin-A we decided to verify whether in normal subjects it was possible to induce, by using the Con-A as a mitogenic factor, the proliferation of cells--possibly T-suppressor--which: a) had the property of adherence and b) show inhibitory activity toward LIF production. The statistical analysis of the results of our experimental patterns show that even if a difference between the suppression exerted on LIF production by Con-A stimulated versus not stimulated cells is present at any dilution, the level of significance rises from P less than 0.005 to P less than 0.0001 for the range of dilution 1:1/4 to 1:132, thus revealing that these experimental conditions are optimal for eliciting the blocking effect. The researches that are currently in progress in our laboratory seem to suggest that this experimental approach is of some value in characterizing the immunity pattern of laryngeal cancer patients and its evolution through the course of disease.
