Recent regulatory initiatives, such as the EU Non-Financial Reporting Directive and the UK Companies Act, require companies to mobilise the business model concept as a framework to disclose non-financial information in the annual report. These regulatory initiatives are based on a reflexive legal approach that avoids specifying what should be disclosed or articulating minimum disclosure requirements. In this context, this study investigates whether and to what extent preparers and users of non-financial information have a shared understanding of the business model concept and its role in reporting. An exploratory survey was conducted involving 35 users and 13 preparers, followed by 13 in-depth interviews, with both stages of research conducted from Searle's perspective of institutional reality. The findings present a somewhat divergent picture, indicating a lack of widespread consensus around a specific definition of a business model, its constitutive elements, and its reporting function. Thus, we conclude that the business model remains a concept under social construction in this domain and highlights areas of intervention. This study contributes to the existing literature by discussing how the absence of a common definition might hinder the otherwise positive effects of business model disclosure regulation from enhancing corporate transparency. Archival studies on business model reporting generally show low levels of disclosure, indicating poor informativeness. Our evidence adds to the accounting literature by considering the role of a shared view of the business model among market participants as a determinant of business model reporting quality and informativeness.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer in patients with liver cirrhosis of various etiologies. In recent years, there has been an advance in the knowledge of molecular mechanisms and a better staging definition of patients which has allowed the development of new therapies that have entered the therapeutic workup of these patients. Deep information on molecular drivers of HCC contributed to the development of targeted therapies with remarkable benefits. The novel strategies of targeting immune evasion using immune checkpoint inhibitors and CAR-T and TCR-T therapeutics have also shown promising results. For advanced diseases, the therapeutic algorithm has been recently updated, thanks to the efficacy of combining immunotherapy and antiangiogenic therapy in the first-line setting, and new drugs, both as single-agents or combinations, are currently under investigation.

Background Novel androgen receptor signaling inhibitors for prostate cancer (PC) impose the burden of self-administration on older patients overwhelmed by the requirement of many other concomitant medications. Patients and Methods This study evaluated the proportion of non-adherence in a 12-month follow-up period and the first 3 months to abiraterone (ABI) or enzalutamide (ENZ). In a prospective multicenter observational cohort study, patients with metastatic castration-resistant PC (mCRPC) aged ≥70 years receiving ABI or ENZ pre- or post-docetaxel were enrolled. Treatment monitoring included pill counting, a self-assessment questionnaire, and clinical diaries at each clinical visit. Non-adherence rates were based on proportions of missed/prescribed pills ratios by pill counting. Results Overall, 234 patients were recruited with median age of 78 years (range, 73–82); 86 (37%) were treated with ABI, and 148 (63%) with ENZ. The median follow-up for adherence was seven monthly cycles (IQR: 4–12). The two cohorts were well balanced for baseline characteristics. The percentage of non-adherence by pill counting was slightly higher for ABI than ENZ (5.2% vs. 4.2%, P < .001). By self-reporting, patients on ENZ tended to report more frequently than those with ABI forgetfulness as the reason for missing events (42% vs. 17%, P < .001). A lower Geriatric G8 score correlated with non-adherence (P = .004). Overall survival (OS) was 48.8 months. Patients on ABI had radiographic progression-free survival (rPFS) of 28.4 [24.2–32.5], while for ENZ patients, we reported a median rPFS of 23.1 [18.2–28.1] months. Conclusion Physicians tend to treat older mCRPC patients with ENZ. Non-adherence rate is relatively low overall but can be higher with ABI than with ENZ and correlates with the Geriatric G8 score. Forgetfulness is a potential barrier for ENZ.

Randomised controlled trials (RCTs) with systemic therapies for patients with pre-treated mesothelioma have reported equivocal efficacy results and generated a degree of clinical uncertainty about the choice of active treatment in this poor prognosis malignancy.To compare the effectiveness and safety and weigh the benefit of different systemic treatments in patients with pre-treated mesothelioma by systematic review, meta-analysis and network meta-analysis of RCTs. Full-text articles and abstracts were searched on PubMed, EMBASE, Cochrane Library and oncology conferences proceedings from 2005 through November 2021 for phase 2 and 3 RCTs. The protocol was submitted to the PROSPERO registry. Reporting followed the PRISMA guideline. Outcomes of interest were overall survival (OS) and progression-free (PFS), grade ≥3 treatment-related (Tr) adverse events (AEs), Tr-deaths and Tr-AEs leading to treatment discontinuation.Nine trials at low risk of bias by Cochrane Collaboration's methodology were included, encompassing 2789 patients. Five studies showed PFS benefit in the experimental treatment. In two studies, OS was prolonged by immunotherapy (versus placebo) or by adding an antiangiogenic agent to chemotherapy. Reported Tr-AE were lower with single-agent anti-PD1 compared with chemotherapy or placebo. The meta-analysis revealed a beneficial global effect on OS and PFS from experimental treatments (HR 0.86, 95% CI 0.77-0.96, p = 0.0083 and HR 0.79, 95% CI 0.72-0.86, p 0.001), that for the PFS significantly favoured the comparison with non-active treatments (HR 0.73, 95% CI 0.66-0.81, p 0.001). Younger patients (i.e. 65-70 years) appeared to benefit the most in OS (HR 0.71, 95% CI 0.55-0.92, p = 0.04). The risk of serious Tr-AEs and Tr-deaths was not significantly increased by experimental treatments (RR 1.38, 95% CI 0.81-2.35, p = 0.24 and RR 2.07, 95% CI 0.69-6.24, p = 0.19, respectively) that instead increased TrAEs leading to treatment discontinuation (RR 2.9, 95% CI 1.44-6.08, p = 0.003). The network meta-analysis did not identify any superior treatment in PFS.For patients with pre-treated MPM, single-agent anti-PD1 or chemotherapy ± the antiangiogenic agent can be considered active and safe systemic therapeutic options, particularly for younger patients.

Fine tuning crop development is a major breeding avenue to increase crop yield and for adaptation to climate change. In this study, we used a model that integrates our current understanding of the physiology of wheat phenology to predict the development and anthesis date of a RILs population of durum wheat with genotypic parameters controlling vernalization requirement, photoperiod sensitivity, and earlinessper seestimated using leaf stage, final leaf number, anthesis date data from a pot experiment with vernalized and nonvernalized treatments combined with short- and long-day length. Predictions of final leaf number and anthesis date of the QTL-based model was evaluated for the whole population of RILs in a set of independent field trials and for the two parents, which were not used to estimate the parameter values. Our novel approach reduces the number of environments, experimental costs, and the time required to obtain the required data sets to develop a QTL-based prediction of model parameters. Moreover, the use of a physiologically based model of phenology gives new insight into genotype-phenology relations for wheat. We discuss the approach we used to estimate the parameters of the model and their association with QTL and major phenology genes that collocate at QTL.HighlightWe used a modeling framework integrating our current understanding of the physiology of wheat phenology to dissect durum wheat time to anthesis into physiological traits and link them to QTL.

This study examines the quality of non-financial disclosure in Strategic Reports, focusing on non-financial key performance indicators (NFKPIs). A vital issue for NFKPI disclosure quality deals with overtime comparability. As NFKPI disclosure is mainly based on managers’ discretional choices regarding which indicators to disclose and how, we argue that corporate governance could play a key role in affecting disclosure practices. The analysis of a sample of UK listed companies from different industries reveals that most companies consistently report NFKPIs and that disclosure practices are influenced by the quality of the board of directors. Additional analyses indicate that among board characteristics, experience in financial key roles is the most effective. Further, intangible intensity is found to be positively associated with NFKPI consistency. Finally, more leveraged and less profitable firms seem to pay more attention to disclosure consistency, supporting the argument that they are subject to more severe scrutiny. This study is the first to examine the relationship between governance quality and NFKPI consistency. It enlarges previous evidence on the relation between corporate governance and disclosure by supporting the role of the board of directors in monitoring non-financial reporting.

Background The current prognostic models for patients with advanced urinary tract cancers were developed and validated in the chemotherapy setting. As immunotherapy has become the backbone of novel treatments, updated prognostic scores are needed. Methods A comprehensive analysis of inflammatory indexes from peripheral blood and clinical factors was planned on the entire real-world cohort of pretreated patients with advanced urinary tract carcinoma receiving atezolizumab in the prospective, single-arm, phase IIIb SAUL study. Univariable and multivariable analyses with overall survival as the primary endpoint, bootstrap internal validation, Schneeweiss scoring system and calibration test were performed to develop a novel immunotherapy prognostic score. Results Thirteen clinical variables from 1001 patients were analysed. The following eight prognostic factors were included in a model: ECOG PS, liver and bone metastases, histology, pre-treatment steroids, systemic immune-inflammatory index (i.e., neutrophils-to-lymphocytes ratio times platelets count), haemoglobin and lactate dehydrogenase. The prognostic model was able to stratify patients into five risk groups with significantly different (p < 0.001) median overall survival of NR, 18.0, 8.7, 4.6 and 2.4 months, respectively. The c-index for OS was higher than the Bellmunt score one (0.702 vs 0.672). Conclusions A novel 5-class prognostic model contemporary to immunotherapy provides robust prognostic discrimination of patients with advanced urinary tract carcinoma homogeneously treated with immunotherapy through baseline affordable and reproducible clinical and laboratory factors. It couls be quickly adopted in clinical practice to inform patients about prognosis with immunotherapy and assess the benefit of novel immunotherapy combinations in clinical trials.

Introduction: Androgen receptor pathway inhibitors (ARPIs) have been increasingly offered to older patients with prostate cancer (PC). However, prognostic factors relevant to their outcome with ARPIs are still little investigated. Methods and Materials: The Meet-URO network ADHERE was a prospective multicentre observational cohort study evaluating and monitoring adherence to ARPIs metastatic castrate-resistant PC (mCRPC) patients aged ≥70. Cox regression univariable and multivariable analyses for radiographic progression-free (rPFS) and overall survival (OS) were performed. Unsupervised median values and literature-based thresholds where available were used as cut-offs for quantitative variables. Results: Overall, 234 patients were enrolled with a median age of 78 years (73–82); 86 were treated with abiraterone (ABI) and 148 with enzalutamide (ENZ). With a median follow-up of 15.4 months (mo.), the median rPFS was 26.0 mo. (95% CI, 22.8–29.3) and OS 48.8 mo. (95% CI, 36.8–60.8). At the MVA, independent prognostic factors for both worse rPFS and OS were Geriatric G8 assessment ≤ 14 (p < 0.001 and p = 0.004) and PSA decline ≥50% (p < 0.001 for both); time to castration resistance ≥ 31 mo. and setting of treatment (i.e., post-ABI/ENZ) for rPFS only (p < 0.001 and p = 0.01, respectively); age ≥78 years for OS only (p = 0.008). Conclusions: Baseline G8 screening is recommended for mCRPC patients aged ≥70 to optimise ARPIs in vulnerable individuals, including early introduction of palliative care.

For decades, chemoradiotherapy for early-stage disease and systemic chemotherapy for advanced disease have represented the mainstay of treatment for anal cancer. Over the last few years, however, the advent of immunotherapy has opened interesting therapeutic perspectives, with the establishment of new standards of care, and the development of clinical trials that may further shape the treatment algorithm for this tumour. In this review article, we discuss the rationale behind the use of immunotherapy for anal cancer and provide an overview of the available clinical data and ongoing efforts to build on these.

Purpose of review To summarize current standards of care, discuss results of recent studies and present ongoing clinical trials for anal squamous cell carcinoma (ASCC). Recent findings Over the last year, no practice changing studies have been reported in the setting of localised ASCC. A number of retrospective analyses, however, have provided practice-informing data, such as those confirming the negative impact of low compliance to chemoradiotherapy (CRT) on patient outcomes. In contrast, and for the first time, randomized evidence has become available to inform the management of advanced tumours. The InterAACT trial represents a key milestone in the evidence-building process for this disease, establishing carboplatin plus paclitaxel as a new standard of care for treatment-naive advanced ASCC patients. Furthermore, more data have accumulated about the value of triplet chemotherapy in the first-line setting and of immune checkpoint inhibitors (either as single agents or in combination with other agents) in the refractory setting. Summary Recent findings have the potential to improve the treatment quality standards and overall outcome of patients with either localised or advanced ASCC. Results from ongoing clinical trials will hopefully provide useful insights into the management of this disease and further shape current treatment paradigms.

BackgroundSecond and third-generation ALK inhibitors (ALKIs) have been recently approved for ALK-translocated lung cancer treatment, improving - and expanding - the first-line scenario.MethodsIn this systematic review and metanalysis, we investigated the efficacy and safety of next-generation ALKIs in untreated advanced ALK-translocated lung cancer patients, searching for randomized phase III controlled trials through databases (PubMed, EMBASE, and the Cochrane Library). Inclusion and exclusion of studies, quality assessment, data extraction, and synthesis were independently accomplished by two reviewers, with discrepancies adjudicated by a third reviewer. Stata (StataCorp., v.16) software was used for the metanalysis.ResultsIn total, seven randomized controlled trials met our inclusion criteria. Comparing the results of next-generation ALKIs and control therapy (crizotinib or chemotherapy), next-generation ALKIs significantly improved progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), any lesion (aCNSRR) and measurable lesions of central nervous system response rate (mCNSRR). Safety results were similar between the experimental and control groups.ConclusionOur analysis confirmed that next-generation ALKIs are the preferred first-line treatment option for ALK-translocated lung cancer. They are superior to crizotinib or chemotherapy in several clinical endpoints, including OS, PFS, ORR and CNS disease control, without increased toxicity. In the absence of head-to-head data, the choice between these molecules should be guided by physician experience and preference, drug-specific safety profile and schedule.

Small cell lung cancer (SCLC) is still a lethal disease. Three phase III randomized clinical trials (IMpower133, CASPIAN, and KEYNOTE-604) have highlighted the survival gain of adding immune checkpoint inhibitors to first-line standard chemotherapy in advanced SCLC patients. In this review, we discuss the data from the three trials above. Furtherly, we analyze issues that still need to be elucidated, like the role of biomarkers, poor performance status at baseline, the presence of brain metastases, and the platinum compound's choice. Moreover, we depict the future of SCLC first-line therapy management, focusing on new therapeutic strategies currently under investigation.

Anti-PD-1 antibodies revolutionized the treatment of advanced melanoma patients. However, one out of three do not respond to this therapy, with an overall poor prognosis. Identification of predictive biomarkers in patients receiving immune-based therapies is necessary for minimizing risk of toxicity and optimizing patient benefit and is still an important unmet clinical need. Recently, many studies have evaluated peripheral blood markers as potential biomarkers, but none so far have been validated. We collected at baseline peripheral blood samples from 18 consecutive advanced melanoma patients treated with anti-PD-1 therapy. Main pro- and anti-inflammatory cytokines were studied in PBMCs from baseline blood samples both evaluating mRNA expression by qRT-PCR and identifying PBMCs subpopulations by FACS analysis. We found that IFN-γ mRNA expression levels were significantly higher in responder patients compared to non-responder ones. Moreover, to better validate its role, we evaluated the IFN-γ/IL-10 ratio. This value was higher in responder patients. FACS analysis confirmed that CD4 + IFN-γ + PBMCs percentage was higher in responders. Our data suggest an interesting correlation between IFN-γ/IL-10 ratio and response to anti-PD-1 therapy in advanced melanoma patients, suggesting a new biomarker that could be easily incorporated in clinical practice.

Background: In accordance with the scientific literature heavy alcohol consumption (>50g per day) represents a risk factor for several diseases development, including cancer. However, the oncogenic role of light alcohol drinking ( Objective: To assess the scientific knowledge about light alcohol consumption and the risk of malignancy onset. Methods: To collect the scientific evidences regarding this topic the keywords “light alcohol drinking”, “light alcohol consumption” and “cancer”, were used. Papers published during the last 15 years were analyzed, in order to select the most recent evidence. Meta-analyses with well-defined levels of alcohol intake were included in the present review. Other studies that focused on biochemical, molecular and genetic aspects, as well as duplicate articles, were excluded. : Furthermore, a possible protective role of light alcohol consumption on the development of bladder, kidney and ovarian cancer and Non Hodgkin Lymphoma was observed. Results: Twenty-nine large, meta-analyses were included in this review. Light alcohol drinking was not associated with an increased risk of cancer occurrence, with the exception of breast and prostate cancer and melanoma. Conclusion: Light alcohol drinking was not associated with the development of several malignancies, except for a light increase of melanoma, breast cancer in women and prostate cancer in men.

Immunotherapy has shifted the therapeutic landscape in thoracic cancers. However, assessment of biomarkers for patient selection and disease monitoring remain challenging, especially considering the lack of tissue sample availability for clinical and research purposes. In this scenario, liquid biopsy (LB), defined as the study and characterization of biomarkers in body fluids, represents a useful alternative strategy. In other malignancies such as colorectal cancer, breast cancer or melanoma, the potential of LB has been more extensively explored for monitoring minimal residual disease or response to treatment, and to investigate mechanisms of resistance to targeted agents. Even if various experiences have already been published about the applications of LB in immunotherapy in thoracic cancers, the standardization of methodology and assessment of its clinical utility is still pending. In this review, the authors will focus on the applications of LB in immunotherapy in non-small cell lung cancer, small cell lung cancer, and malignant pleural mesothelioma, describing available data and future perspectives.

Background FKBP51 immunophilin is abundantly expressed by immune cells. Co-inhibitory immune receptor signalling generates the splicing isoform FKBP51s. Tregs stained by FKBP51s are increased in melanoma patients and their counts are associated with anti-CTLA-4 response. An expansion of FKBP51s+PD-L1+ monocytes was measured in a group of non-responding patients to anti-CTLA-4. The aim of this work was to confirm the predictive value of response of FKBP51s+Tregs in a cohort of patients undergoing anti-PD1 treatment and shed light on a monocyte subset co-expressing PD-L1/FKBP51s. Methods Co-cultures of organoids and autologous lymphocytes were used to confirm that tumour T-cell interaction can induce FKBP51s. PBMC immunophenotype and flow cytometry served to assess and monitor FKBP51s+Treg and FKBP51s+PD-L1+ monocytes in 22 advanced melanoma patients treated with anti-PD1. Silencing and overexpression of FKBP51s in human macrophages served to address the protein role in the tolerant macrophages’ behaviour. Results FKBP51s+Tregs count was increased in responders and had a prognostic value. Non-responders showed an early increase in FKBP51s+ PD-L1+ monocytes during anti-PD1 treatment. Manipulation of FKBP51s modulated the macrophage–phenotype, with forced protein expression promoting aspects associated with tolerance. Conclusions FKBP51s may guide in the selection and monitoring of melanoma patient candidates to immune-checkpoint-targeted therapy. Manipulation of FKBP51s may overcome resistance.

Background: Cutaneous melanoma is one of the most severe skin diseases. Nodular melanoma is the second melanoma subtype in order of frequency. The prognosis of skin melanoma depends on the vertical growth of the tumor (Breslow index). For this measurement, excisional biopsy is strongly recommended. This is, however, an invasive procedure and may cause damage to the lymphatic drainage system. The HFUS system, , can be extremely useful for determining tumor thickness in the preoperative phase, given its high resolution capacity. The aim of this preliminary study is to define the role of HFUS for the nodular skin melanoma Breslow thickness in adults before surgery by making a comparison with histological features. Methods: In this study, 14 melanocytic lesions (8 male and 6 female) were evaluated with dermatoscopic clinical features strongly indicative of nodular melanoma. Out of these, excisional biopsy of 7 lesions was requested. The ultrasounds were performed preoperatively. The images were acquired through the first ultrasound scanner with ultra-high frequency probes (range from 50MHz to 70 MHz) available on the market under the EEC mark (Vevo "MD, FUJIFILM Visual Sonics, Amsterdam, the Netherlands) equipped with a linear probe of 50-70 MHz. Results: From the ultrasonographic analysis of 14 nodular melanoma thickness was determined for the presence of two hyperechogenic laminae, separated by a hypo / anechoic space. The twelve lesions were in situ while the other two lesions showed ultrasonography for example; the satellite lesions (less than two centimeters from the primary lesion) and in transit (localizable to more than two centimeters from the primary lesion). Four of these lesions were ulcerated. A comparsion was made the 7 lesions on between the thickness calculated with this method, and that obtained on the bioptic piece. The presence of a positive concordance has been evident in all of the cases. Conclusions: If further studies are needed to support its widespread clinical use, its is believed that, in expert hands and with an interdisciplinary team, HFUS is already capable to reliably calculate a Breslow index in a large majority of patients with cutaneous melanoma.

Biliary tract cancer (BTC) is an aggressive tumor characterized by a poor prognosis. In the latest years, targetable genetic alterations have been discovered in BTC patients, leading to the approval of new targeted therapies. Liquid biopsy, which is a non-invasive method for detecting tumor biomarkers from fluid samples, is a useful tool for diagnosis and molecular characterization, but also for prognosis assessment and monitoring of treatment response. In this review, recent works on liquid biopsy in BTC patients were analyzed, focusing on some relevant aspects for clinical use and trying to depict the future role of this technique. Moreover, differences between plasma and bile samples were pointed out, in light of the peculiar biology of BTC and the possibility of using bile as an alternative source of cell-free DNA (cfDNA) for genomic analysis. In the era of precision oncology, the increasing adoption of liquid biopsy in BTC patients will certainly improve the management of this disease.

Background: Liquid biopsy is a potentially useful tool for melanoma patients, also for detecting BRAS/NRAS mutations, even if the tissue analysis remains the current standard. Methods: In this work, we tested ctDNA on plasma samples from 56 BRAF-V600/NRAS mutant stage III/IV melanoma patients using a real-time quantitative PCR (qPCR)-based platform. The study population was divided into two cohorts: the first including 26 patients who had undergone radical resection (resected cohort) and the second including 30 patients who had unresected measurable disease (advanced cohort). Moreover, for 10 patients in the advanced cohort, ctDNA assessment was repeated at specified timepoints after baseline testing. Data were analyzed and correlated to the clinicopathologic characteristics and outcomes. Results: In the baseline cohort, a higher tissue–plasma concordance was seen in patients with high burden of disease (sum of diameters ≥30 mm, ≥2 metastatic sites, elevated LDH levels); furthermore, monitoring of these patients through ctDNA analysis was informative for therapeutic responses. On the other hand, the low sensitivity of this technique did not allow for clinically valuable prediction of relapses in radically resected stage III/IV patients. Conclusions: Overall, our data suggest that qPCR-based ctDNA analysis could be informative in a subset of locally advanced and metastatic melanoma patients with specific clinical–radiological characteristics, supporting further investigations in this setting.

48 Background: 68Ga prostate specific membrane antigen positron emission tomography/computed tomography (68Ga-PSMA PET/CT) is a highly sensitive diagnostic tool to detect prostate metastatic sites even at low levels of Prostate Specific Antigen (PSA). We evaluated the impact of 68Ga-PSMA PET/CT in patients treated with enzalutamide as first-line therapy for mCRPC. Methods: In an observational prospective study, 67 consecutive mCRPC patients were treated with enzalutamide 160 mg once daily in first-line for mCRPC. 68Ga-PSMA PET/CT was performed at baseline, after 3 months, during follow-up and at PSA/clinical progression. Patients were evaluated on a monthly basis for serological PSA response and safety. We measured at baseline the sum of metabolic total volume (SMTV), mean standardized uptake volume (SSUVmean), maximum standardized uptake volume (SSUVmax) and total lesion activity (STLA), which is the product of SMTV and SSUVmean, for a maximum of 20 lesions. These parameters together with baseline PSA level, Eastern Cooperative Oncology Group performance status (ECOG PS), Gleason Score (GS) and age were analyzed by univariate and multivariate Cox regression models as potential predictors of progression-free survival (PFS) and overall survival (OS). Results: At the moment of the present analysis, 58 mCRPC patients were considered fully evaluable. The median age was 75 years (range, 47-91), ECOG PS was 0 in 47 cases (81%), 1-2 in 11 (19%), GS was 3, median SSUVmax of 44.85, median SSUVmean of 25.80 and median STLA of 59.66. At the median follow-up of 52 months, median PFS was 28.9 months (95% CI 16.3-43.6), median OS was not reached (95% CI 36.8-not reached). In univariate analysis, SSUVmax and STLA were significant for PFS (p=0.015 and p=0.001, respectively) and OS (p=0.026 and p=0.019, respectively), while SSUVmean was significant only for OS (p=0.028). On multivariate analysis, STLA only remained significant for PFS (p68Ga-PSMA PET/CT before starting enzalutamide was associated with longer median PFS and OS compared to prior studies using standard imaging only. STLA, expression of both volume and intensity of 68Ga-PSMA uptake, appeared the strongest parameter able to predict PFS and OS.

214 Background: Up to 80% of mCRPC have bone metastases and about 25% of metastatic prostate cancer harbor mutations in DNA damage repair defects (DDR). DDR gene mutations are a negative prognostic factor, being associated with short metastasis-free survival and cancer-specific survival. We analyzed the impact of somatic mutations in DDR genes on bone-related efficacy endpoints in mCRPC. Methods: We retrospectively analyzed the mutational status of mCRPC patients per FoundationOne analysis in tissue biopsy or, when it was not possible, in liquid biopsy (performed at the onset of mCRPC). We evaluated the impact of DDR gene mutations on bone-related efficacy endpoints at the time of mCRPC diagnoses, by dividing patients in two main groups (mutated DDR, specifically, mutations in at least one of BRCA1/2, ATM, FANCA, ATR, CHEK2, RAD51, PALB2, and CDK12 genes: group A; wild-type DDR: group B). We investigated differences between the two groups in terms of time from bone metastases onset to death, skeletal metastatic tumor burden (sites and number of lesions), skeletal-related events (SRE) incidence, and time to first on-study SRE. Results: Of the 131 patients with mCRPC enrolled, 115 had bone metastases. Clinical data distribution, according to molecular profile, is presented. There is no difference in terms of sites of metastases and time from bone metastases onset to death between the 2 groups. Mutated DDR status was associated with bone metastases volume (p = 0.0325), but did not affect SRE incidence and time to SRE onset. Conclusions: In our analysis, mutated DDR status was associated with higher bone metastases volume, although a not detrimental effect on the other bone-related efficacy endpoints was observed.

Mucosal melanomas (MM) are rare tumors, being less than 2% of all diagnosed melanomas, comprising a variegated group of malignancies arising from melanocytes in virtually all mucosal epithelia, even if more frequently found in oral and sino-nasal cavities, ano-rectum and female genitalia (vulva and vagina). To date, there is no consensus about the optimal management strategy of MM. Furthermore, the clinical rationale of molecular tumor characterization regarding BRAF, KIT or NRAS, as well as the therapeutic value of immunotherapy, chemotherapy and targeted therapy, has not yet been deeply explored and clearly established in MM. In this overview, focused on anorectal and genital MM as models of rare melanomas deserving of a multidisciplinary approach, we highlight the need of referring these patients to centers with experts in melanoma, anorectal and uro-genital cancers treatments. Taking into account the rarity, the poor outcomes and the lack of effective treatment options for MM, tailored research needs to be promptly promoted.

Simple Summary Prostate cancer research has been recently characterized by the discovery of several prognostic and predictive molecular factors, which ultimately improve patients’ management. In this review, we present the clinical impact of such factors and the methods to detect them, both on tissue and blood, in advanced prostate cancer patients. The aim of this review is ultimately to depict the role of these molecular factors in the era of precision oncology. Abstract Prostate cancer (PCa) therapy has been recently revolutionized by the approval of new therapeutic agents in the metastatic setting. However, the optimal therapeutic strategy in such patients should be individualized in the light of prognostic and predictive molecular factors, which have been recently studied: androgen receptor (AR) alterations, PTEN-PI3K-AKT pathway deregulation, homologous recombination deficiency (HRD), mismatch repair deficiency (MMRd), and tumor microenvironment (TME) modifications. In this review, we highlighted the clinical impact of prognostic and predictive molecular factors in PCa patients’ outcomes, identifying biologically distinct subtypes. We further analyzed the relevant methods to detect these factors, both on tissue, i.e., immunohistochemistry (IHC) and molecular tests, and blood, i.e., analysis of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA). Moreover, we discussed the main pros and cons of such techniques, depicting their present and future roles in PCa management, throughout the precision medicine era.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease even in the early stages, despite progresses in surgical and pharmacological treatment in recent years. High potential for metastases is the main cause of therapeutic failure in localized disease, highlighting the current limited knowledge of underlying pathological processes. However, nowadays research is focusing on the search for personalized approaches also in the adjuvant setting for PDAC, by implementing the use of biomarkers and investigating new therapeutic targets. In this context, the aim of this narrative review is to summarize the current treatment scenario and new potential therapeutic approaches in early stage PDAC, from both a preclinical and clinical point of view. Additionally, the review examines the role of target therapies in localized PDAC and the influence of neoadjuvant treatments on survival outcomes.

Cutaneous melanoma is a lethal disease, even when diagnosed in advanced stages. Although recent progress in biology and treatment has dramatically improved survival rates, new therapeutic approaches are still needed. Deregulation of epigenetics, which mainly controls DNA methylation status and chromatin remodeling, is implied not only in cancer initiation and progression, but also in resistance to antitumor drugs. Epigenetics in melanoma has been studied recently in both melanoma preclinical models and patient samples, highlighting its potential role in different phases of melanomagenesis, as well as in resistance to approved drugs such as immune checkpoint inhibitors and MAPK inhibitors. This review summarizes what is currently known about epigenetics in melanoma and dwells on the recognized and potential new targets for testing epigenetic drugs, alone or together with other agents, in advanced melanoma patients.

OBJECTIVE: The aim of this review is to analyze feasibility and toxicities of high-dose chemotherapy (HDCT) in comparison to standard dose chemotherapy (SDCT) in patients affected by mediastinal germ cell tumors (MGCTs), discussing factors that may affect therapeutic choices, such as: management of residual disease, early response predictors for chemotherapeutic efficacy and determinants of chemotherapeutic resistance. In this review, we discuss the main clinical experiences with HDCT and SDCT in germ cell tumor (GCT) patients specifically in those affected by MGCT. BACKGROUND: MGCTs represent a very small subset characterized by a poor prognosis, despite improvements in their clinical management and in understanding their biology. From early 1970s, HDCT has become an alternative to SDCT for both first-line and salvage therapeutic settings in advanced GCT patients. Several HDCT schedules—either cisplatin or carboplatin-based—have been tested so far, both in clinical randomized trial and in single-center experiences, with divergent results in terms of clinical outcomes and tolerability. Moreover, the majority of these studies included, but were not exclusively designed for, advanced MGCT patients, making difficult to infer data for this specific subset. METHODS: an extended review of literature through PubMed was conducted using the keywords “mediastinal germinal cell tumors”, “standard dose chemotherapy” and “high dose chemotherapy”. CONCLUSIONS: HDCT regimens could not be considered to date a standard option as first-line therapy in advanced MGCT patients, whilst they could be an alternative to SDCT regimens in relapsed tumors after proper patient selection.

The cure rate of germ cell tumours (GCTs) has significantly increased from the late 1970s since the introduction of cisplatin-based therapy, which to date remains the milestone for GCTs treatment. The exquisite cisplatin sensitivity has been mainly explained by the over-expression in GCTs of wild-type TP53 protein and the lack of TP53 somatic mutations; however, several other mechanisms seem to be involved, many of which remain still elusive. The findings about the role of TP53 in platinum-sensitivity and resistance, as well as the reported evidence of second cancers (SCs) in GCT patients treated only with surgery, suggesting a spectrum of cancer predisposing syndromes, highlight the need for a deepened understanding of the role of TP53 in GCTs. In the following report we explore the complex role of TP53 in GCTs cisplatin-sensitivity and resistance mechanisms, passing through several recent genomic studies, as well as its role in GCT patients with SCs, going through our experience of Center of reference for both GCTs and cancer predisposing syndromes.

Metastatic melanoma treatment has dramatically changed in the last few years, having a breakthrough with the introduction of targeted agents and immunotherapy. PD-1/PD-L1 pathway is one of the physiologic mechanisms of peripheral immune tolerance, but it also represents a mechanism of tumor immune escape. PD-1/PD-L1 inhibitors represent new immune-checkpoint drugs currently used in metastatic melanoma treatment. : Resistance to PD-1/PD-L1 axis blockade, which is the main cause of therapeutic failure during therapeutic use of these drugs, could be linked to several mechanism of immune escape. In fact, other inhibitory receptor such as CTLA-4, LAG-3, TIM-3 and TIGIT might be co-expressed on T cells, deleting the effect of anti-PD-1/PD-L1; overexpression of the enzyme IDO could cause immunosuppression through the depletion of tryptophan in the tumor microenvironment; defective c ostimulation (through reduced activity of 4-1BB and OX40 receptors) could result in T-cell energy. : Combination of anti-PD-1/PD-L1 with drugs targeting inhibitory or costimulatory receptors, intracellular pathways, enzymes or neoangiogenesis could be a possible strategy to overcome resistance to single PD-1/PD-L1 blockade. Clinical trials evaluating combination therapies have already showed interesting results, although most of them are still on going.

Both durum and bread wheat are well adapted to Mediterranean environments where durum wheat is traditionally assigned to more stressful conditions. Twenty-seven cultivars of each species were grown under 4 environments in Sardinia (Italy) to characterize the differences in grain yield and protein between and within them. The large number of cultivars revealed large within-species variability in yield and no or just minor between-species differences, which indicated bread wheat as better performing (6.9 vs. 6.2 t ha−1 on average). The number of grains m-2 (GNO) was 34% higher for bread wheat, and derived from the 26% more spikes m-2, associated with a slightly higher maximum Leaf Area Index (5.74 vs. 5.29), a higher leaf porosity and Photochemical Reflectance Index around anthesis, and higher NDVI. The high GNO of bread wheat was responsible for its lower nitrogen content (mg grain−1), which resulted in a lower protein percentage in spite of its lower grain weight (36 vs. 44 mg). The combination of a high GNO and low grain weight for bread wheat was particularly advantageous under favourable post-anthesis environmental conditions. The genotypic variation in yield was more dependent on grain weight than on GNO for bread wheat, whereas the opposite was true for durum wheat. These results suggest to orient breeding at increasing grain weight in bread and GNO in durum wheat. Cultivar choice seems to be more important than species choice in terms of productivity, despite the contrasting ways through which the two species generate their yield.
