[What affects diagnostic and therapeutic times for cancer patients care?] / Cosa influisce sui tempi diagnostici e terapeutici dei pazienti oncologici?

INTRODUCTION: According with "Numbers of cancer in Italy. 2021" mortality is decreasing for both the genders (-10% for men, -8% for women) in Italy. However, this trend is not uniform and seems stable in the Southern regions. Analyses of oncological care in Campania Region highlighted some structural critical issues and delays, which did not guarantee an efficient and effective use of the available economic resources. So, the Campania region established in September 2016 the Campania oncological network (Roc) addressed to prevention, diagnosis, treatment and rehabilitation of tumours through the establishment of multidisciplinary oncological groups (Gom). In February 2020, the ValPeRoc project was launched with the aim of periodically and progressively evaluating the Roc's performance both for the clinical services and for the economic aspects. METHODS: In five Goms (colon, ovary, lung, prostate, bladder) active in some Roc hospitals, the pre-Gom time elapsing between the date of diagnosis and the date of the first Gom meeting and the Gom time elapsing between the date of the first Gom meeting and the date of the treatment decision were measured. Gom times longer than 28 days were defined as high. The risk of high Gom time was analyzed with a Bart-type machine learning algorithm, considering the set of regressors (features) available to classify patients. RESULTS: The results on the test set (54 patients) report an accuracy of 0.68. The classification technique reported a good fit for colon Gom (93%) and an over-classification for lung Gom. The study of the marginal effects showed a higher risk for those who had a previous therapeutic act and for lung Gom. CONCLUSIONS: Within the Goms took in consideration the proposed statistical technique showed that, depending on each Gom, correctly classified about 70% of individuals on risk of delaying permanence within the Roc. The ValPeRoc project evaluates Roc activity for the first time through a replicable analysis of patient pathway times from diagnosis to the act of treatment. Specifically, the times analyzed measure the quality of the regional health care system.

Bimodal antibody-titer decline following BNT162b2 mRNA anti-SARS-CoV-2 vaccination in healthcare workers of the INT - IRCCS "Fondazione Pascale" Cancer Center (Naples, Italy).

BACKGROUND: Both SARS-CoV-2 mRNA-based vaccines [BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna)] have shown high efficacy, with very modest side effects in limiting transmission of SARS-CoV-2 and in preventing the severe COVID-19 disease, characterized by a worrying high occupation of intensive care units (ICU), high frequency of intubation and ultimately high mortality rate. At the INT, in Naples, only the BNT162b2/Pfizer vaccine has been administered to cancer patients and healthcare professionals aged 16 and over. In the present study, the antibody response levels and their decline were monitored in an interval of 6-9 months after vaccine administration in the two different cohorts of workers of the INT - IRCCS "Fondazione Pascale" Cancer Center (Naples, Italy): the group of individuals previously infected with SARS-CoV-2 and vaccinated with a single dose; and that of individuals negative for previous exposure to SARS-CoV-2 vaccinated with two doses 21 days apart. METHODS: Specific anti-RBD (receptor-binding domain) titers against trimeric spike glycoprotein (S) of SARS-CoV-2 by Roche Elecsys Anti-SARS-CoV-2 S ECLIA immunoassay were determined in serum samples of 27 healthcare workers with a previously documented history of SARS-CoV-2 infection and 123 healthcare workers without, during antibody titers' monitoring. Moreover, geometric mean titers (GMT) and relative fold changes (FC) were calculated. RESULTS: Bimodal titer decline was observed in both previously infected and uninfected SARS-CoV-2 subjects. A first rapid decline was followed by a progressive slow decline in the 6/9 month-period before the further vaccine boost. The trend was explained by 2 different mathematical models, exponential and power function, the latter revealing as predictive of antibody titer decline either in infected or in not previously infected ones. The value of the prolonged lower vaccine titer was about 1 log below in the 6/9-month interval after the single dose for previously infected individuals with SARS-CoV-2 and the two doses for those not previously infected. The titer change, after the boost dose administration, on the other hand, was ≥ 1.5 FC higher than the titers at the 6/9-month time-points in both cohorts. A similar quantitative immune titer was observed in both cohorts 8 days after the last boost dose. The subsequent immunoresponse trend remains to be verified. DISCUSSION: The results show that a very rapid first decline, from the highest antibody peak, was followed by a very slow decline which ensured immune protection lasting more than 6 months. The apparent absence of adverse effects of the rapid decline on the vaccine's immune protective role has been related to a large majority of low avidity antibodies induced by current vaccines. High avidity antibodies with prolonged anti-transmission efficacy show a longer half-life and are lost over a longer interval period. The cellular immunity, capable of preventing severe clinical diseases, lasts much longer. The unbalanced dual activity (cellular vs humoral) while effective in limiting ICU pressure and overall mortality, does not protect against transmission of SARS-CoV-2, resulting in high circulation of the virus among unvaccinated subjects, including the younger population, and the continuous production of variants characterized by changes in transmissibility and pathogenicity. The high mutation rate, peculiar to the RNA virus, can however lead to a dual opposite results: selection of defective and less efficient viruses up to extinction; risk of more efficiently transmitted variants as the current omicron pandemic. CONCLUSIONS: In conclusion the current bimodal antibody-titer decline, following BNT162b2 mRNA anti-SARS-CoV-2 vaccination, needs a further extended analysis to verify the protective borderline levels of immunity and the optimal administration schedule of vaccine boosters. Our current results can contribute to such goal, besides a direct comparison of other FDA-approved and candidate vaccines.

A SARS-CoV-2 Infection High-Uptake Program on Healthcare Workers and Cancer Patients of the National Cancer Institute of Naples, Italy.

BACKGROUND: From the beginning of 2020, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) quickly spread worldwide, becoming the main problem for the healthcare systems. Healthcare workers (HCWs) are at higher risk of infection and can be a dangerous vehicle for the spread of the virus. Furthermore, cancer patients (CPs) are a vulnerable population, with an increased risk of developing severe and lethal forms of Coronavirus Disease 19 (COVID-19). Therefore, at the National Cancer Institute of Naples, where only cancer patients are treated, a surveillance program aimed to prevent the hospital access of SARS-CoV-2 positive subjects (HCWs and CPs) was implemented. The study aims to describe the results of the monitoring activity for the SARS-CoV-2 spread among HCWs and CPs, from March 2020 to March 2021. METHODS: This surveillance program included a periodic sampling through nasopharyngeal molecular swabs for SARS-CoV-2 (Real-Time Polymerase Chain Reaction, RT-PCR). CPs were submitted to the molecular test at least 48 h before hospital admission. Survival analysis and multiple logistic regression models were performed among HCWs and CPs to assess the main SARS-CoV-2 risk factors. RESULTS: The percentages of HCWs tested with RT-PCR for the detection of SARS-CoV-2, according to the first and the second wave, were 79.7% and 91.7%, respectively, while the percentages for the CPs were 24.6% and 39.6%. SARS-CoV-2 was detected in 20 (1.7%) HCWs of the 1204 subjects tested during the first wave, and in 127 (9.2%) of 1385 subjects tested in the second wave (p < 0.001); among CPs, the prevalence of patients tested varied from 100 (4.6%) during the first wave to 168 (4.9%) during the second wave (p = 0.8). The multivariate logistic analysis provided a significant OR for nurses (OR = 2.24, 95% CI 1.23-4.08, p < 0.001) compared to research, administrative staff, and other job titles. CONCLUSIONS: Our findings show that the positivity rate between the two waves in the HCWs increased over time but not in the CPs; therefore, the importance of adopting stringent measures to contain the shock wave of SARS-CoV-2 infection in the hospital setting was essential. Among HCWs, nurses are more exposed to contagion and patients who needed continuity in oncological care for diseases other than COVID-19, such as suspected cancer.

New approach to implement cancer patient care: The valutazione percorso rete oncologica campana (ValPeROC)-experience from an Italian oncology network.

OBJECTIVE: The primary goal of the Campania Oncology Network (ROC) was to reduce cancer delay and care fragmentation through the establishment of cancer-specific multidisciplinary oncologic groups (GOMs) and diagnostic and therapeutic assistance paths (PDTAs). METHODS: Five cancer centres of the ROC, with their own cancer specific GOM, were selected. In our analysis, we have focused on four neoplasms: lung, colon, ovarian and prostate cancers. The median time for pre-GOM and GOM Times was calculated for each tumour site. Univariate and multivariate logistic regressions were performed to individuate risk factors for pre-GOM and GOM Time. RESULTS: Significant differences were observed for prostate cancer compared to other patients either for pre-GOM or GOM Times. Significant risks were found for ovarian and prostate cancers in pre-GOM time and for prostate cancer in GOM-Time. CONCLUSIONS: This experience will produce knowledge and data to guide decision-making and to manage more effectively the challenges of fighting cancer in Campania region. The Valutazione Percorso Rete Oncologica Campana (ValPeROC) study evaluates, for the first time, the ROC activity, through the analysis of key performance indices. Pre-GOM and GOM Time represent the quality of the entire regional health system and are useful to define models, which can evaluate the performance of the ROC over time.

HLA Does Not Impact on Short-Medium-Term Antibody Response to Preventive Anti-SARS-Cov-2 Vaccine.

The response to anti-SARS-Cov-2 preventive vaccine shows high interpersonal variability at short and medium term. One of the explanations might be the individual HLA allelic variants. Indeed, B cell response is stimulated and sustained by CD4+ T helper cells activated by antigens presented by HLA-class II alleles on antigen-presenting cells (APCs). The impact of the number of antigens binding to HLA class-II alleles on the antibody response to the COVID vaccine has been assessed in a cohort of 56 healthcare workers who received the full schedule of the Pfizer-BioNTech BNT162b2 vaccine. Such vaccine is based on the entire spike protein of the SARS-CoV-2. Ab titers have been evaluated 2 weeks after the first dose as well as 2 weeks and 4 months after the boosting dose. HLA-DRB1 and DBQ1 for each of the vaccinees have been assessed, and strong binders have been predicted. The analysis showed no significant correlation between the short-medium-term Ab titers and the number of strong binders (SB) for each individual. These results indicate that levels of Ab response to the spike glycoprotein is not dependent on HLA class II allele, suggesting an equivalent efficacy at global level of the currently used vaccines. Furthermore, the pattern of persistence in Ab titer does not correlate with specific alleles or with the number of SBs.

Robotic radical cystectomy with concomitant implantation of 3-piece penile prosthesis: a one-step solution.

Radical cystectomy (RC) remains a highly morbid urologic procedure, and erectile dysfunction (ED) represents a significant burden for bladder cancer survivors. While inflatable penile prosthesis (IPP) offers a definitive treatment option for post-RC ED, the hostile postoperative anatomy of RC patients poses some technical challenges for IPP implantation. We report the case of a 54-year-old male with high grade bladder cancer who was managed with a robotic-assisted RC with Bricker ileal conduit urinary diversion and simultaneous implantation of a 3-piece IPP. Operative time was 310 min (230 min for the RC and ileal conduit portion, 80 min for IPP implantation). Estimated blood loss was 300 ml. Postoperative course was regular. The patient was discharged home on postoperative day 6. A robotic RC with concomitant IPP implantation can be offered as "one-step" solution to bladder cancer male patients. This approach can potentially offer the advantage of better outcome in terms of sexual function, while minimizing surgical risks, ultimately improving the quality of life of these patients.

Vaccination strategy and anti - SARS-CoV-2 S titers in healthcare workers of the INT - IRCCS "Fondazione Pascale" Cancer Center (Naples, Italy).

BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and the resulting disease, coronavirus disease 2019 (COVID-19), have spread to millions of people globally, requiring the development of billions of different vaccine doses. The SARS-CoV-2 spike mRNA vaccine (named BNT162b2/Pfizer), authorized by the FDA, has shown high efficacy in preventing SARS-CoV-2 infection after administration of two doses in individuals 16 years of age and older. In the present study, we retrospectively evaluated the differences in the SARS-CoV-2 humoral immune response after vaccine administration in the two different cohorts of workers at the INT - IRCCS "Fondazione Pascale" Cancer Center (Naples, Italy): previously infected to SARS-CoV-2 subjects and not infected to SARS-CoV-2 subjects. METHODS: We determined specific anti-RBD (receptor-binding domain) titers against trimeric spike glycoprotein (S) of SARS-CoV-2 by Roche Elecsys Anti-SARS-CoV-2 S immunoassay in serum samples of 35 healthcare workers with a previous documented history of SARS-CoV-2 infection and 158 healthcare workers without, after 1 and 2 doses of vaccine, respectively. Moreover, geometric mean titers and relative fold changes (FC) were calculated. RESULTS: Both previously infected and not infected to SARS-CoV-2 subjects developed significant immune responses to SARS-CoV-2 after the administration of 1 and 2 doses of vaccine, respectively. Anti-S antibody responses to the first dose of vaccine were significantly higher in previously SARS-CoV-2-infected subjects in comparison to titers of not infected subjects after the first as well as the second dose of vaccine. Fold changes for subjects previously infected to SARS-CoV-2 was very modest, given the high basal antibody titer, as well as the upper limit of 2500.0 BAU/mL imposed by the Roche methods. Conversely, for naïve subjects, mean fold change following the first dose was low ([Formula: see text] =1.6), reaching 3.8 FC in 72 subjects (45.6%) following the second dose. CONCLUSIONS: The results showed that, as early as the first dose, SARS-CoV-2-infected individuals developed a remarkable and statistically significant immune response in comparison to those who did not contract the virus previously, suggesting the possibility of administering only one dose in previously SARS-CoV-2-infected subjects. FC for previously infected subjects should not be taken into account for the generally high pre-vaccination values. Conversely, FC for not infected subjects, after the second dose, were = 3.8 in > 45.0% of vaccinees, and ≤ 3.1 in 19.0%, the latter showing a potential susceptibility to further SARS-CoV-2 infection.

Evaluation of the diagnostic accuracy of a new point-of-care rapid test for SARS-CoV-2 virus detection.

BACKGROUND: The easy access to a quick diagnosis of coronavirus disease 2019 (COVID-19) is a key point to improve the management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and to contain its spread. Up to now, laboratory real-time PCR is the standard of care, but requires a fully equipped laboratory and significant infrastructure. Consequently, new diagnostic tools are required. METHODS: In the present work, the diagnostic accuracy of the point-of-care rapid test "bKIT Virus Finder COVID-19" (Hyris Ltd) is evaluated by a retrospective and a prospective analysis on SARS CoV-2 samples previously assessed with an FDA "authorized for the emergency use-EUA" reference method. Descriptive statistics were used for the present study. RESULTS: Results obtained with the Hyris Kit are the same as that of standard laboratory-based real time PCR methods for all the analyzed samples. In addition, the Hyris Kit provides the test results in less than 2 h, a significantly shorter time compared to the reference methods, without the need of a fully equipped laboratory. CONCLUSIONS: To conclude, the Hyris kit represents a promising tool to improve the health surveillance and to increase the capacity of SARS-CoV-2 testing.

Post-Acute COVID-19 Rehabilitation Network Proposal: From Intensive to Extensive and Home-Based IT Supported Services.

Management of COVID-19 post-acute syndrome is an emerging health issue in rehabilitation. This article aims to present a proposal, based on the principles of clinical governance, health management and information technology (IT), and to respond to the need for a structured organization model for post-acute COVID-19 rehabilitation. The authors present a regional-based model of a network of clinicians and healthcare managers using a dedicated IT platform to achieve both effectiveness and efficiency objectives, to ensure coordination of the available resources and the most appropriate rehabilitative treatment for patients. The proposed post-acute COVID-19 rehabilitation network has been designed according to the model of a clinical management project within the Italian national healthcare system, and its context is an easily adjustable model for the European healthcare systems. The authors base the project on current laws and scientific guidelines in rehabilitation in Italy and in Europe and use the SWOT analysis technique to assess the proposal feasibility. The primary aims of the project are: (1) standardizing the minimum assessment tools of post-COVID-19 patients with disabilities; (2) ensuring an individual rehabilitation project for each patient with international classification of functioning, disability and health (ICF) coding and (3) reporting the activity performance with appropriate indicators. The secondary aims are: (1) developing educational programs for patients and care givers also aimed at acquiring better empowerment and positive behavior; (2) creating a regional database for data collection and (3) improving IT, and specifically tele-rehabilitation, as a suitable approach during the COVID-19 emergency and also in the future. Expected results are: continuum of care; effectiveness, efficacy and appropriateness in the delivery of rehabilitation treatments through a standardized minimum assessment and the wording of the individual rehabilitation project and a precise reporting of performance indicators to measure the effectiveness of clinical activities and the satisfaction of patients and caregivers. The assessment of results will be analyzed at three and six months to implement corrective actions according to the concept of continuous improvement of the Deming cycle. The IT remote approach allows the patient to meet the needs of proximity of care and empowerment, and, at the same time, to contain the spread of infection. This project could have a significant healthcare impact ensuring a more efficient and effective management of the demand of rehabilitation post-acute COVID-19, expanding the professional skills of the rehabilitation team members, improving both clinical and process data, in addition to optimal allocation of available economic resources.

The clinical and translational research activities at the INT - IRCCS "Fondazione Pascale" cancer center (Naples, Italy) during the COVID-19 pandemic.

COVID-19 pandemic following the outbreak in China and Western Europe, where it finally lost the momentum, is now devastating North and South America. It has not been identified the reason and the molecular mechanisms of the two different patterns of the pulmonary host responses to the virus from a minimal disease in young subjects to a severe distress syndrome (ARDS) in older subjects, particularly those with previous chronic diseases (including diabetes) and cancer. The Management of the Istituto Nazionale Tumori - IRCCS "Fondazione Pascale" in Naples (INT-Pascale), along with all Health professionals decided not to interrupt the treatment of those hospitalized and to continue, even if after a careful triage in order not to allow SARS-CoV-2 positive subjects to access, to take care of cancer patients with serious conditions. Although very few (n = 3) patients developed a symptomatic COVID-19 and required the transfer to a COVID-19 area of the Institute, no patients died during the hospitalization and completed their oncology treatment. Besides monitoring of the patients, all employees of the Institute (physicians, nurses, researchers, lawyers, accountants, gatekeepers, guardians, janitors) have been tested for a possible exposure. Personnel identified as positive, has been promptly subjected to home quarantine and subdued to health surveillance. One severe case of respiratory distress has been reported in a positive employees and one death of a family member. Further steps to home monitoring of COVID-19 clinical course have been taken with the development of remote Wi-Fi connected digital devices for the detection of early signs of respiratory distress, including heart rate and oxygen saturation.In conclusion cancer care has been performed and continued safely also during COVID-19 pandemic and further remote home strategies are in progress to ensure the appropriate monitoring of cancer patients.

Epithelial-mesenchymal transition in prostate cancer: an overview.

Prostate cancer is a main urological disease associated with significant morbidity and mortality. Radical prostatectomy and radiotherapy are potentially curative for localized prostate cancer, while androgen deprivation therapy is the initial systemic therapy for metastatic prostate disease. However, despite temporary response, most patients relapse and evolve into castration resistant cancer.Epithelial-mesenchymal transition (EMT) is a complex gradual process that occurs during embryonic development and/or tumor progression. During this process, cells lose their epithelial characteristics and acquire mesenchymal features. Increasing evidences indicate that EMT promotes prostate cancer metastatic progression and it is closely correlated with increased stemness and drug resistance.In this review, we discuss the main molecular events that directly or indirectly govern the EMT program in prostate cancer, in order to better define the role and the mechanisms underlying this process in prostate cancer progression and therapeutic resistance.

Characterization and burden of Campania children health migration across Italian regions during years 2006-2010: chance and/or necessity?

BACKGROUND: To evaluate medical, economical and sociological variables underlying avoidable pediatric migration from Campania region. METHODS: Analysis of years 2006-2010 hospital discharge records, extracted from the archive of Regional Health Agency (ArSan), classified by Major Diagnostic Categories, Aggregate Clinical Codes, Discipline of dismissal, Local Health Authorities of residence, and age group 0-14 years (excluding those of healthy newborns). Sociological variables were evaluated by questionnaires. RESULTS: A total of 68,316 hospital discharge records were released by extra-regional structures. Major diagnostic categories and Discipline of dismissal indicated that the most implicated diseases (nervous system and mental disorders, hematology-oncology, and bone diseases) were not always of very high complexity. The total cost paid by the Campania Region was 124.700.000 Euros. The need for more specialized hospital pediatric units and/or with more pediatric subspecialties in the native region was pointed out by most of the self-administered questionnaires. CONCLUSIONS: Pediatric migration is an important phenomenon with evident implications. The identification of the most concerned sub-specialties here reported can give useful information aiming to assist in the improvement of the existing pediatric resources in Campania region in the wider context of the national global child health advancement.
