Patient presentation, skin biopsy utilization and cutaneous malignant melanoma incidence and mortality in northern Italy: Trends and correlations.

BACKGROUND: The global increase in incidence of cutaneous malignant melanoma (CMM) occurring in the past decades has been partly attributed to increased diagnostic scrutiny of early lesions, with a potential phenomenon of overdiagnosis. The reported positive linear relation between skin biopsy rate and incidence of early CMM is compatible with this hypothesis. OBJECTIVES: We explored the ecological association between the trends in annual dermatologic office visit rates, skin biopsy rates, incidence rates of in situ and invasive CMM by tumour thickness category, and CMM mortality rates in the Emilia-Romagna Region (northern Italy). METHODS: Four cancer registries covering a population of 2,696,000 provided CMM incidence data for the years 2003-2017. Dermatologic office visit rates and skin biopsy rates were calculated using the Regional outpatient care database. All rates were age-standardized. Trends were described with the estimated average annual per cent change (EAAPC). Correlations were tested with the Spearman correlation coefficient. RESULTS: Incidence increased significantly. The increase was steeper for in situ CMM (EAAPC: men, 10.2; women, 6.9) followed by CMM <0.8 mm thick (9.1; 5.2), but the rates grew significantly for most subgroups of CMMs ≥0.8 mm thick. Mortality decreased significantly among women (-2.3) and non-significantly among men. For dermatologic office visit rate and skin biopsy rate the EAAPC were, respectively, 1.7 and 1.8 for men and 1.2 and 0.9 for women. Annual dermatologic office visit rate correlated with skin biopsy rate in both sexes. However, the proportion of skin biopsies out of dermatologic office visits was constant across the years (range: men, 0.182-0.216; women, 0.157-0.191). CONCLUSIONS: In Italy, the increasing CMM incidence trend is, at least in part, genuine. Overdiagnosis-if any-is due to an increased patient presentation at dermatologic offices and not to a lower dermatologic threshold to perform biopsy.

The relative contribution of the decreasing trend in tumour thickness to the 2010s increase in net survival from cutaneous malignant melanoma in Italy: a population-based investigation.

BACKGROUND: The long-term increase in survival from cutaneous malignant melanoma (CMM) is generally attributed to the decreasing trend in tumour thickness, the single most important prognostic factor. OBJECTIVES: To determine the relative contribution of decreased tumour thickness to the favourable trend in survival from CMM in Italy. METHODS: Eleven local cancer registries covering a population of 8 056 608 (13.4% of the Italian population in 2010) provided records for people with primary CMM registered between 2003 and 2017. Age-standardized 5-year net survival was calculated. Multivariate analysis of 5-year net survival was undertaken by calculating the relative excess risk (RER) of death. The relative contribution of the decrease in tumour thickness to the RER of death was evaluated using a forward stepwise flexible parametric survival model including the available prognostic factors. RESULTS: Over the study period, tumour thickness was inversely associated with 5-year net survival and multivariate RER in both sexes. The median thickness was 0.90 mm in 2003-2007, 0.85 mm in 2008-2012 and 0.75 mm in 2013-2017 among male patients, and 0.78 mm, 0.77 mm and 0.68 mm among female patients, respectively. The 5-year net survival was 86.8%, 89.2% and 93.2% in male patients, and 91.4%, 92.0% and 93.4% in female patients, respectively. In 2013-2017, male patients exhibited the same survival as female patients despite having thicker lesions. For them, the increasing survival trend was more pronounced with increasing thickness, and the inclusion of thickness in the forward stepwise model made the RER in 2013-2017 vs. 2003-2007 increase from 0.64 [95% confidence interval (CI) 0.51-0.80] to 0.70 (95% CI 0.57-0.86). This indicates that the thickness trend accounted for less than 20% of the survival increase. For female patients, the results were not significant but, with multiple imputation of missing thickness values, the RER rose from 0.74 (95% CI 0.58-0.93) to 0.82 (95% CI 0.66-1.02) in 2013-2017. CONCLUSIONS: For male patients in particular, decrease in tumour thickness accounted for a small part of the improvement in survival observed in 2013-2017. The introduction of targeted therapies and immune checkpoint inhibitors in 2013 is most likely to account for the remaining improvement.

Impact of the COVID-19 pandemic on head and neck cancer diagnosis: data from a single referral center, South Tyrol, northern Italy.

OBJECTIVE: The aim of the study was to evaluate the impact of the COVID-19 pandemic on new diagnoses of head and neck cancer (HNC) in South Tyrol, northern Italy in terms of the number of new diagnoses and worsening disease stage due to diagnostic delay. METHODS: Patients were divided into two groups: the control group with a first diagnosis of HNC in 10 months before the national lockdown (March 9th, 2020) and the study group with a first diagnosis of HNC in 10 months after lockdown. RESULTS: A total of 124 patients were included in the study. Before the spread of COVID-19, 79 new diagnoses of HNCs were registered, while in the period after the lockdown, 45 new cancers cases were diagnosed and the difference was statistically significant (p = 0.01278). Early clinical T-stage results showed 52 cases in the control group and 21 in the study group, again with a significant difference (p = 0.03711). Advanced T-stage results showed 27 cases in the control group and 24 in the study group. CONCLUSIONS: This study highlights the impact of the COVID-19 pandemic on HNCs, showing a statistically significant difference in the number of diagnoses before and after the lockdown which was related to the spread of the SARS-CoV-2 virus, and with a relevant decrease in early cT-staged HNCs.

Livedoid skin reaction to 2nd dose of mRNA Covid-19 vaccine.

Skin often represents a target organ for adverse drug reactions and this also applies to the mRNA vaccines against Sars-CoV-2. Here we present a case of extensive livedoid reaction after 2nd dose of BNT162b-2 vaccine with massive blood skin extravasation and no systemic symptoms apart from anemization. The 30-year-old woman developed progressively enlarging livedoid lesions on limbs and abdomen. Histology showed a near-normal epidermis and a very mild interstitial mixed inflammatory infiltrate with extensive blood extravasation in mid- and deep dermis. Diagnosis was adverse reaction to vaccine with skin capillary hyperpermeability and anaemization with lower than diagnostic features of cutaneous small vessel vasculitis. To date, no cases of a livedoid skin reaction associated to Covid-19 vaccine have been reported, and this case illustrates that massive livedoid reaction can be another kind of skin reaction to mRNA Covid-19 vaccine.

Mid-term trends and recent birth-cohort-dependent changes in incidence rates of cutaneous malignant melanoma in Italy.

In Oceania, North America and north-western Europe, after decades of increase, cutaneous malignant melanoma (CMM) rates began to stabilise or decline before 2000. Anecdotal evidence suggests that the reversal of the incidence trend is extending to southern Europe. To obtain a formal confirmation, this nationwide study from Italy investigated the incidence trends by birth cohort. Twenty-one local cancer registries covering a population of 15 814 455 provided incidence data for primary CMM registered between 1994 and 2013. Trends in age-standardised rates were analysed using joinpoint regression models and age-period-cohort models. Age-standardised incidence showed a consistent increase throughout the period (estimated annual percent change, 3.6 [95% confidence interval, 3.2-4.0] among men and 2.5 [2.0-3.1] among women). This pattern was confirmed by a sensitivity analysis with removal of low-risk populations of southern Italy. The rates, however, showed a stabilisation or a decrease in men and women aged below 35. Using the cohort of 1949-the median cohort with respect to the number of cases for both genders-as a reference, the incidence rate ratio increased for successive cohorts born until 1973 (women) and 1975 (men), and subsequently tended to decline. For the most recent cohorts in both genders, the risk of disease returned to the level of the cohort of 1949. The changes observed in the latest generations can be interpreted as the earliest manifestations of a birth-cohort-dependent incidence decrease. Our study adds to previous data indicating that the reversal of the long-term upward incidence trend of CMM is extending to southern Europe.

[The new national guidelines for the keeping of the Italian Sinonasal Cancer Registry (ReNaTuNS)]. / Il nuovo manuale operativo ReNaTuNS per la gestione dei casi di tumore naso-sinusale.

Sinonasal cancers (SNC) are rare tumours with predominant occupational aetiology associated with exposures to specific carcinogens. In Italy, SNC incidence has been under compulsory surveillance since 2008, through the National Sinonasal Cancer Registry (ReNaTuNS), a nationwide cancer registry coordinated by the National Institute for Insurance Against Accidents at Work (Inail). The ReNaTuNS has a regional structure with local registries, established at Regional Operating Centres (CORs). Currently, seven Italian Regions are active in SNC search and, together with Inail, have recently released a new version of the national guidelines for keeping the Registry (available on the Inail website). The aim of this text is to present the new guidelines, an updating version, and to underline the relevance of this tool in enforcing the role of the ReNaTuNS, considering the high occupational fraction of SNC and the unicity of the Italian Registry, which collects all the information available on occupational exposures of each SNC case registered. It is recommended that the active search for SNC cases and the analysis of exposure become a systematic and well-organized activity to prevent or reduce risks of exposure and to support and improve the efficiency of the compensation and welfare system.

Incidence trends of vulvar squamous cell carcinoma in Italy from 1990 to 2015.

OBJECTIVE: The incidence of vulvar squamous cell carcinoma has increased for decades in most Western countries - a trend virtually restricted to women aged <50 or 60 years. In southern Europe, conversely, the trends have been insufficiently studied. This article reports a study from Italy. METHOD: Thirty-eight local cancer registries, currently covering 15,274,070 women, equivalent to 49.2% of the Italian national female population, participated. Invasive cancers registered between 1990 and 2015 with an International Classification of Diseases for Oncology, 3rd revision, topography code C51 and morphology codes compatible with vulvar squamous cell carcinoma (n = 6294) were eligible. Incidence trends were analysed using joinpoint regression models, with calculation of the estimated annual percent change (EAPC), and age-period-cohort models. RESULTS: Total incidence showed a regular and significant decreasing trend (EAPC, -0.96; 95% confidence interval (CI), -1.43 to -0.48). This was entirely accounted for by women aged ≥60 years (EAPC, -1.34; 95% CI, -1.86 to -0.81). For younger women, the EAPC between 1990 and 2012 was 1.20 (95% CI, 0.34 to 2.06) with a non-significant acceleration thereafter. This pattern did not vary substantially in a sensitivity analysis for the effect of geographic area and duration of the registry. The age-period-cohort analysis revealed a risk decrease in cohorts born between 1905 and 1940 and a new increase in cohorts born since 1945. CONCLUSIONS: The decreasing trend observed among older women and the resulting decrease in total rate are at variance with reports from most Western countries. Age-period-cohort analysis confirmed a decreasing trend for earliest birth cohorts and an opposite one for recent ones.

The epidemiological surveillance of malignant mesothelioma in Italy (1993-2015): methods, findings, and research perspectives.

BACKGROUND: as a legacy of the large asbestos consumption until the definitive ban in 1992, Italy had to tackle a real epidemic of asbestos related diseases. The Italian National Registry of Malignant Mesotheliomas (ReNaM) is a permanent surveillance system of mesothelioma incidence, with a regional structure. Aims, assignments and territorial network of ReNaM are described, as well as data collection, recording and coding procedures. OBJECTIVES: to describe the Italian epidemiological surveillance system of mesothelioma incidence, to provide updated data about occurrence of malignant mesothelioma in Italy, and to discuss goals, attainments, and expectations of registering occupational cancer. DESIGN: analysis of data by malignant mesothelioma incident cases surveillance system. SETTING AND PARTICIPANTS: Italy, network of regional surveillance system, all Italian regions. MAIN OUTCOME MEASURES: a Regional Operating Centre (COR) is currently established in all the Italian regions, actively searching incident malignant mesothelioma cases from health care institutions. Occupational history, lifestyle habits, and residential history are obtained using a standardized questionnaire, administered to the subject or to the next of kin by a trained interviewer. The extent of dataset, epidemiological parameters, and occupations involved are reported updated at 31.12.2016, and standardized incidence rates are calculated. RESULTS: at December 2016, ReNaM has collected 27,356 malignant mesothelioma cases, referring to the period of incidence between 1993 and 2015. The modalities of exposure to asbestos have been investigated for 21,387 (78%) and an occupational exposure has been defined for around 70% of defined cases (14,818). CONCLUSIONS: the Italian experience shows that epidemiological systematic surveillance of asbestos related diseases incidence has a key importance for assessing and monitoring the public health impact of occupational and/or environmental hazards, programming preventive interventions, including remediation plans and information campaigns, and supporting the efficiency of insurance and welfare system. Monitoring the incidence of malignant mesothelioma through a specialized cancer registry is essential to follow-up the health effects of changing modalities and extent of occupational exposures over years and of environmental contamination. Such consolidated surveillance system is recommended also for occupational cancers with low aetiological fraction.

Characteristics of people living in Italy after a cancer diagnosis in 2010 and projections to 2020.

BACKGROUND: Estimates of cancer prevalence are widely based on limited duration, often including patients living after a cancer diagnosis made in the previous 5 years and less frequently on complete prevalence (i.e., including all patients regardless of the time elapsed since diagnosis). This study aims to provide estimates of complete cancer prevalence in Italy by sex, age, and time since diagnosis for all cancers combined, and for selected cancer types. Projections were made up to 2020, overall and by time since diagnosis. METHODS: Data were from 27 Italian population-based cancer registries, covering 32% of the Italian population, able to provide at least 7 years of registration as of December 2009 and follow-up of vital status as of December 2013. The data were used to compute the limited-duration prevalence, in order to estimate the complete prevalence by means of the COMPREV software. RESULTS: In 2010, 2,637,975 persons were estimated to live in Italy after a cancer diagnosis, 1.2 million men and 1.4 million women, or 4.6% of the Italian population. A quarter of male prevalent cases had prostate cancer (n = 305,044), while 42% of prevalent women had breast cancer (n = 604,841). More than 1.5 million people (2.7% of Italians) were alive since 5 or more years after diagnosis and 20% since ≥15 years. It is projected that, in 2020 in Italy, there will be 3.6 million prevalent cancer cases (+ 37% vs 2010). The largest 10-year increases are foreseen for prostate (+ 85%) and for thyroid cancers (+ 79%), and for long-term survivors diagnosed since 20 or more years (+ 45%). Among the population aged ≥75 years, 22% will have had a previous cancer diagnosis. CONCLUSIONS: The number of persons living after a cancer diagnosis is estimated to rise of approximately 3% per year in Italy. The availability of detailed estimates and projections of the complete prevalence are intended to help the implementation of guidelines aimed to enhance the long-term follow-up of cancer survivors and to contribute their rehabilitation needs.

The epidemiology of malignant mesothelioma in women: gender differences and modalities of asbestos exposure.

INTRODUCTION: The epidemiology of gender differences for mesothelioma incidence has been rarely discussed in national case lists. In Italy an epidemiological surveillance system (ReNaM) is working by the means of a national register. METHODS: Incident malignant mesothelioma (MM) cases in the period 1993 to 2012 were retrieved from ReNaM. Gender ratio by age class, period of diagnosis, diagnostic certainty, morphology and modalities of asbestos exposure has been analysed using exact tests for proportion. Economic activity sectors, jobs and territorial distribution of mesothelioma cases in women have been described and discussed. To perform international comparative analyses, the gender ratio of mesothelioma deaths was calculated by country from the WHO database and the correlation with the mortality rates estimated. RESULTS: In the period of study a case list of 21 463 MMs has been registered and the modalities of asbestos exposure have been investigated for 16 458 (76.7%) of them. The gender ratio (F/M) was 0.38 and 0.70 (0.14 and 0.30 for occupationally exposed subjects only) for pleural and peritoneal cases respectively. Occupational exposures for female MM cases occurred in the chemical and plastic industry, and mainly in the non-asbestos textile sector. Gender ratio proved to be inversely correlated with mortality rate among countries. CONCLUSIONS: The consistent proportion of mesothelioma cases in women in Italy is mainly due to the relevant role of non-occupational asbestos exposures and the historical presence of the female workforce in several industrial settings. Enhancing the awareness of mesothelioma aetiology in women could support the effectiveness of welfare system and prevention policies.

Predominant expression of truncated EpCAM is associated with a more aggressive phenotype and predicts poor overall survival in colorectal cancer.

Regulated intramembrane proteolysis (RIP) has been shown to be an important mechanism for oncogenic activation of EpCAM through nuclear translocation of the intracellular domain EpICD. Recently, we identified two different membranous EpCAM variants namely EpCAM(MF) (full-length) and EpCAM(MT) (truncated) to be expressed in the majority of human epithelial tumors. The aim of our study was to evaluate the potential role of these two protein variants as additional prognostic biomarkers in colorectal cancer. In most studies only one antibody targeting the extracellular domain of EpCAM (EpEX) has been used, whereas in the present study additionally an antibody which detects the intracellular domain (EpICD) was applied to discriminate between different EpCAM variants. Using immunohistochemistry, we analyzed the expression of EpCAM(MF) and EpCAM(MT) variants in 640 patients with colorectal cancer and determined their correlations with other prognostic factors and clinical outcome. A statistically significant association was observed for EpCAM(MT) with advanced tumor stage (p < 0.001), histological grade (p = 0.01), vascular (p < 0.001) and marginal (p = 0.002) invasion. Survival analysis demonstrated reduced overall survival (p < 0.004) in patients with tumors expressing the EpCAM(MT) phenotype when compared to patients with tumors expressing the EpCAM(MF) variant. In conclusion, this study for the first time indicates that expression of EpCAM(MT) is associated with a more aggressive phenotype and predicts poor survival in patients with colorectal cancer.

Prognostic value of prior history of urothelial carcinoma of the bladder in patients with upper urinary tract urothelial carcinoma: results from a retrospective multicenter study.

BACKGROUND: Patients with urothelial carcinoma (UC) often develop multifocal metachronous tumors throughout the genitourinary tract. In the present study, we evaluated the prognostic value of prior history of UC of the bladder (UCB) in patients with upper tract urothelial carcinoma (UTUC) in an international multi-institutional cohort. PATIENTS AND METHODS: Data from 785 patients who underwent radical nephroureterectomy (RNU) with ipsilateral bladder cuff resection at nine academic institutions in Europe and the USA between 1987 and 2008 were reviewed. Log-rank tests and Cox proportional hazards regression models were used for univariable and multivariable analyses. RESULTS: The median follow-up of the whole cohort was 34 months (interquartile range 15-66 months). Five hundred and fifty-eight (72 %) patients had no UCB before the diagnosis of UTUC; a prior history of non-muscle-invasive and muscle-invasive UCB before the UTUC was found in 179 (23 %) and 36 (5 %), respectively. History of UCB before RNU was an independent predictor of both recurrence-free survival (p = 0.012; no UCB vs. non-muscle-invasive UCB: hazard ratio (HR) 1.4, p = 0.082; no UCB vs. muscle-invasive UCB: HR 2.1, p = 0.007) and cancer-specific survival (p = 0.008; no UCB vs. non-muscle-invasive UCB: HR 1.2, p = 0.279; no UCB vs. muscle-invasive UCB: HR 2.3, p = 0.008) on multivariable Cox regression analyses that included age, gender, surgical type, stage, grade, presence of concomitant carcinoma in situ, presence of lymphovascular invasion, and lymph node status. CONCLUSIONS: Prior history of muscle-invasive UCB was significantly associated with an increased risk of disease recurrence and cancer-specific death in patients with UTUC.

Loss of membranous expression of the intracellular domain of EpCAM is a frequent event and predicts poor survival in patients with pancreatic cancer.

AIMS: Epithelial cell adhesion molecule (EpCAM) is a widely used immunohistochemical marker for epithelial human malignancies. Antibodies to target EpCAM are usually directed against its ectodomain (EpEX), but do not detect the intracellular domain (EpICD). The aim of this study was to compare membranous EpEX versus EpICD expression by immunohistochemistry. METHODS AND RESULTS: Concurrent EpEX and EpICD expression was investigated retrospectively in cancerous and matched non-neoplastic tissue samples from patients with pancreatic adenocarcinoma. In total, 317 paired samples of pancreatic tissue from 88 patients were analysed and correlated with clinicopathological parameters. In non-cancerous tissue, a high concordance of membranous EpEX and EpICD expression was observed and defined as the expression of the full-length EpCAM (EpEX(+)/EpICD(+) phenotype, EpCAM(MF)), which was highly predominant. In contrast, while most tumour samples were EpEX positive, loss of membranous EpICD expression (EpEX(+)/EpICD(-) phenotype, EpCAM(MT)) was observed in one-third of cases, and these patients had a significantly shortened disease-free and overall survival. CONCLUSIONS: This study demonstrates for the first time that loss of membranous EpICD expression is a frequent event and predicts poor prognosis in patients with pancreatic cancer. Additional studies evaluating the predictive and prognostic value of the expression of different membranous EpCAM variants are warranted in epithelial cancers.

Multiple aneurysms of the radial artery in a woman with neurofibromatosis type 1 presenting as aneurysm rupture.

A 48-year-old woman with neurofibromatosis type 1 (NF1) experienced progressive forearm swelling coupled with impending compartment syndrome. Computed tomography angiography revealed a ruptured aneurysm of the proximal radial artery, multiple fusiform radial artery aneurysms, and a high independent ulnar artery origin. Compartment syndrome required prompt hematoma evacuation. Radial artery reconstruction, technically demanding due to vessel wall fragility, was deemed unnecessary because of satisfactory blood supply to the hand. Histologic findings indicated NF1-related vascular abnormalities also in the apparently normal radial artery as well as in a forearm vein, suggesting diffused vasculopathy. This case report is the first on ruptured radial artery aneurysm in NF1-related polianeurysmatic degeneration.

Cancer and Pregnancy: Estimates in Italy from Record-Linkage Procedures between Cancer Registries and the Hospital Discharge Database.

The aim of this study is to describe the frequency and trend of pregnancy-associated cancer (PAC) in Italy, an increasingly relevant phenomenon due to postponing age at childbirth. To this purpose, a population-based retrospective longitudinal study design based on cohorts of women aged 15-49 diagnosed with cancer and concomitant pregnancy is proposed. The study uses 19 population-based Cancer Registries, covering about 22% of Italy, and linked at an individual level with Hospital Discharge Records. A total of 2,861,437 pregnancies and 3559 PAC are identified from 74,165 women of the cohort with a rate of 1.24 PAC per 1000 pregnancies. The most frequent cancer site is breast (24.3%), followed by thyroid (23.9%) and melanoma (14.3%). The most frequent outcome is delivery (53.1%), followed by voluntary termination of pregnancy and spontaneous abortion (both 12.0%). The trend of PAC increased from 2003 to 2015, especially when the outcome is delivery, thus confirming a new attitude of clinicians to manage cancer throughout pregnancy. This represents the first attempt in Italy to describe PAC from Cancer Registries data; the methodology is applicable to other areas with the same data availability. Evidence from this study is addressed to clinicians for improving clinical management of women with PAC.

The descriptive epidemiology of melanoma in Italy has changed - for the better.

A recent research project using data from a total of 40 cancer registries has provided new epidemiologic insights into the results of efforts for melanoma control in Italy between the 1990s and the last decade. In this article, the authors present a summary and a commentary of their findings. Incidence increased significantly throughout the study period in both sexes. However, the rates showed a stabilization or a decrease in men and women aged below 35 years. The risk of disease increased for successive cohorts born until 1973 (women) and 1975 (men) while subsequently tending to decline. The trend towards decreasing tumor thickness and increasing survival has continued, but a novel favorable prognostic factor has emerged since 2013 for patients - particularly for males - with thick melanoma, most likely represented by molecular targeted therapies and immune checkpoint inhibitors. Due to this, the survival gap between males and females has been filled out. In the meanwhile, and despite the incidence increase, dermatologists have not lowered their threshold to perform skin biopsy. Skin biopsy rate has increased because of the increasingly greater volume of dermatologic office visits, but the proportion of skin biopsies out of dermatologic office visits has remained constant. In summary, an important breakthrough in melanoma control in Italy has taken place. Effective interventions have been implemented across the full scope of care, which involve many large local populations - virtually the whole national population. The strategies adopted during the last three decades represent a valuable basis for further steps ahead in melanoma control in Italy.

Trends in Net Survival from Vulvar Squamous Cell Carcinoma in Italy (1990-2015).

(1) Objective: In many Western countries, survival from vulvar squamous cell carcinoma (VSCC) has been stagnating for decades or has increased insufficiently from a clinical perspective. In Italy, previous studies on cancer survival have not taken vulvar cancer into consideration or have pooled patients with vulvar and vaginal cancer. To bridge this knowledge gap, we report the trend in survival from vulvar cancer between 1990 and 2015. (2) Methods: Thirty-eight local cancer registries covering 49% of the national female population contributed the records of 6274 patients. Study endpoints included 1- and 2-year net survival (NS) calculated using the Pohar-Perme estimator and 5-year NS conditional on having survived two years (5|2-year CNS). The significance of survival trends was assessed with the Wald test on the coefficient of the period of diagnosis, entered as a continuous regressor in a Poisson regression model. (3) Results: The median patient age was stable at 76 years. One-year NS decreased from 83.9% in 1990-2001 to 81.9% in 2009-2015 and 2-year NS from 72.2% to 70.5%. Five|2-year CNS increased from 85.7% to 86.7%. These trends were not significant. In the age stratum 70-79 years, a weakly significant decrease in 2-year NS from 71.4% to 65.7% occurred. Multivariate analysis adjusting for age group at diagnosis and geographic area showed an excess risk of death at 5|2-years, of borderline significance, in 2003-2015 versus 1990-2002. (4) Conclusions: One- and 2-year NS and 5|2-year CNS showed no improvements. Current strategies for VSCC control need to be revised both in Italy and at the global level.

Frozen section telepathology service: Efficiency and benefits of an e-health policy in South Tyrol.

Objective/Background: Telepathology has been widely adopted to allow intraoperative pathology examinations to be performed remotely and for obtaining second opinion teleconsultation. In the Italian northern region of South Tyrol, the widespread geographical distances and consequent cost for the health system of having a travelling pathologist cover intraoperative consultations in peripheral hospitals was a key driver for the implementation of a telepathology system. Methods: In 2010, four Menarini D-Sight whole slide scanners to digitize entire pathology slides were placed in the peripheral hospitals of Merano, Bressanone, Brunico, and in the hub hospital of Bolzano. Digital workstations were also installed to allow pathologists to remotely perform intraoperative consultations with digital slides. This study reviews the outcome after 12 years of telepathology for this intended clinical use. Results: After an initial validation phase with 100 cases which yielded a sensitivity of 65% (CI 43-84%) and specificity of 100% (CI 95-100%), there were 2058 intraoperative consultations handled by telepathology. The cases evaluated were mainly breast sentinel lymph nodes, followed by urological, gynecological and general surgical pathology frozen section specimens. There were no false-positive cases and 165 (8%) false-negative cases, yielding an overall sensitivity and specificity of 65% (CI 61-69%) and 100% (CI 99-100%), respectively. Conclusion: Telepathology is reliable for remote intraoperative diagnosis and, despite technical issues and initial acquaintance issues, proved beneficial for patient care in satellite hospitals, improved standardization, promoted innovation, and resulted in cost savings for the health system.

The impact of COVID-19 on new mesothelioma diagnoses in Italy.

BACKGROUND: The aim of this work was to evaluate the impact of the restrictions put in place to control the COVID-19 pandemic on new diagnoses of malignant mesothelioma (MM) in Italy. METHODS: Twelve of the 21 Italian malignant mesothelioma CORs (regional operating centres) participated. The study included all cases of MM with microscopic confirmation; cases without microscopic confirmation and death certificate only (DCO) were excluded. For each case, information on sex, date of birth, tumor site, morphology, and date of diagnosis was retrieved. We compared the number of incident cases in 2020 with 2019, looking at the overall picture and for four periods: pre-pandemic (January-February), first wave (March-May), low incidence (June-September), and second wave (October-December). RESULTS: A total of 604 cases were registered: 307 in 2019 and 297 in 2020. In the 2020 pre-pandemic period, the incidence was higher than in the same months in 2019 (+45%); there was no significant change during the first wave (+1%) or in the low-incidence period (-3%), while a decrease was observed during the second wave (-32%). However, the data were not homogeneous across the country: the increase in the pre-pandemic period concerned mostly the regions of northern (+61.5%) and central Italy (+43.5%); during the first wave, MM diagnoses increased in the northern (+38.5%) and central (+11.4%) regions but decreased in the southern regions (-52.9%). All these differences are compatible with random fluctuations. CONCLUSION: The COVID-19 pandemic had little or no impact on new MM diagnoses, and variations were not homogeneous throughout the country.
