Diagnosis of lung cancer following emergency admission: Examining care pathways, clinical outcomes, and advanced NSCLC treatment in an Italian cancer Center.

Background: Lung cancer patients diagnosed following emergency admission often present with advanced disease and poor performance status, leading to suboptimal treatment options and outcomes. This study aimed to investigate the clinical and molecular characteristics, treatment initiation, and survival outcomes of these patients. Methods: We retrospectively analyzed data from 124 patients diagnosed with lung cancer following emergency admission at a single institution. Clinical characteristics, results of molecular analyses for therapeutic purpose, systemic treatment initiation, and survival outcomes were assessed. Correlations between patients' characteristics and treatment initiation were analyzed. Results: Median age at admission was 73 years, and 79.0 % had at least one comorbidity. Most patients (87.1 %) were admitted due to cancer-related symptoms. Molecular analyses were performed in 89.5 % of advanced non-small cell lung cancer (NSCLC) cases. In this subgroup, two-thirds (66.2 %) received first-line therapy. Median overall survival (OS) was 3.9 months for the entire cohort, and 2.9 months for patients with metastatic lung cancer. Among patients with advanced NSCLC, OS was significantly longer for those with actionable oncogenic drivers and those who received first-line therapy. Improvement of performance status during hospitalization resulted in increased probability of receiving first-line systemic therapy. Discussion: Patients diagnosed with lung cancer following emergency admission demonstrated poor survival outcomes. Treatment initiation, particularly for patients with actionable oncogenic drivers, was associated with longer OS. These findings highlight the need for proactive medical approaches, including improving access to molecular diagnostics and targeted treatments, to optimize outcomes in this patient population.

Investigating the Ovarian Microstructure in the Genera Helicolenus and Scorpaena (Teleostei, Sub-Order Scorpaenoidei) with Implications for Ovarian Dynamics and Spawning.

The sub-order Scorpenoidei appears to be particularly interesting due to the presence of intermediate stages between oviparity and viviparity in several species. The present study aims to describe the ovarian morphology, using a histological and histochemical approach, in four ovuliparous species belonging to Scorpaena genus compared with a zygoparous species, H. dactylopterus, focusing also on the assessment of the ovarian dynamics in the populations of such species in Sardinia waters (central-western Mediterranean). Ovarian sections of all species were examined using light microscopy. All species showed a specialized ovary, cystovarian type II-3, strictly related to the production of gelatinous matrices surrounding the eggs. Some microscopic peculiarities in the oogenesis process were found: thin zona pellucida, small and low cortical alveoli, and a specialized ovarian wall during the spawning period. All species analyzed were batch-spawners with an asynchronous ovarian organization. A continuous recruitment of oocytes and the occurrence of de novo vitellogenesis was also observed. During the spawning period, low atresia intensity was detected, while a marked increase in this intensity found in the ovaries at the end of spawning season. Our observations may support an indeterminate fecundity type for these species.

Living naked: first case of lack of skin-related structures in an elasmobranch, the blackmouth catshark (Galeus melastomus).

As far as is known, in this paper the first case of lacking of skin-related structures (epidermis, stratum laxum, dermal denticles and teeth) in a free-swimming elasmobranch, the blackmouth catshark, Galeus melastomus, is reported. The individual was caught by trawl in Sardinian waters (central-western Mediterranean) in July 2019 at a depth of 500 m. Although this kind of morphological abnormality is potentially fatal, the observations suggested that the specimen was in good health and well developed.

Serial Troponin for Early Detection of Nivolumab Cardiotoxicity in Advanced Non-Small Cell Lung Cancer Patients.

BACKGROUND: Rare cases of severe myocarditis are reported during treatment with nivolumab. Troponin, a biomarker of cardiac damage, is a key component of the diagnostic workup of many cardiac disorders, including myocarditis. This study investigates the role of troponin to assess cardiac involvement during nivolumab therapy for non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: We evaluated 59 NSCLC patients, analyzing serum samples collected within a translational research study. Troponin above the upper normal limit (0.046 ng/mL) was defined as Tn+, whereas normal but detectable troponin (0.015-0.045) was defined as Tndet. Troponin alterations were interpreted on the grounds of the following elements: peak values and time curve, cardiac comorbidities, signs and symptoms coincident to troponin elevation, ECG, echocardiography, and disease progression. RESULTS: No patient had cardiovascular events. Among 362 available blood samples, Tn+ (max 0.317 ng/mL) was found in 13 determinations belonging to 6 patients. Seven other patients had isolated Tndet. In five patients, Tn+ was attributed to cardiac comorbidities, disease progression, or worsening clinical status. One patient without cardiac history and in good clinical condition had a sustained troponin increase-soon after the start of therapy-and after careful evaluation of all relevant elements, it was interpreted as a marker of nivolumab-related subclinical myocarditis. CONCLUSION: Tn+ may occur in NSCLC patients treated with nivolumab, but in most cases it does not indicate nivolumab cardiotoxicity. In some cases, however, a careful interpretation of troponin alteration, especially at the beginning of therapy, enables identification of subclinical myocarditis, thus allowing early cardiac treatment. IMPLICATIONS FOR PRACTICE: Myocarditis is a rare but serious adverse event of immune checkpoint blockade with nivolumab, which needs to be recognized as soon as possible. This article suggests that troponin, a user-friendly biomarker of myocardial cytotoxicity, might be useful for early detection of immune-mediated myocarditis. However, because troponin abnormalities might also be related to a number of conditions capable of causing myocardial oxygen demand-supply mismatch, a careful cardiac assessment should be performed in non-small cell lung cancer patients in order to properly interpret any troponin increase. According to the available evidence, monitoring troponin during the first weeks of treatment can be considered reasonable.

Abiraterone acetate and prednisone in the pre- and post-docetaxel setting for metastatic castration-resistant prostate cancer: a mono-institutional experience focused on cardiovascular events and their impact on clinical outcomes.

BACKGROUND: The aim of this work was to to evaluate the incidence and risk factors of adverse events (AEs), focusing on cardiovascular events (CVEs) and hypokalemia, in patients treated with abiraterone acetate (AA) and prednisone (PDN) outside clinical trials, and their association with survival outcomes. METHODS: This was a retrospective cohort study of 105 patients treated from 2011 to 2016. Incidence of AEs was descriptively summarized in the whole cohort and by subgroup (pre- versus post-docetaxel). Multivariable Cox proportional hazards models assessed factors associated with progression-free survival (PFS) and overall survival (OS). RESULTS: Overall, median PFS and OS were 14.9 and 24.6 months, respectively. Prostate-specific antigen (PSA) ⩾ 10 ng/ml (p = 0.007), Gleason Score >7 (p = 0.008), Eastern Cooperative Oncology Group (ECOG) performance status (PS)1-2 (p = 0.002), duration of androgen deprivation therapy (ADT) ⩽ 43.2 months (p = 0.01), and body mass index (BMI) > 25 (p = 0.03) were associated with worse PFS; presence of pain (p = 0.01), ECOG PS1-2 (p = 0.004), duration of ADT ⩽ 43.2 (p = 0.05), and BMI > 25 (p = 0.042) were associated with worse OS. Incidence of CVEs was as follows: hypertension 17.1%, fluid retention 4.8%, cardiac disorders 8.6%. 16.2% of patients developed hypokalemia. Age ⩾ 75 years was associated with higher probability of cardiac disorders (p = 0.001) and fluid retention (p = 0.03). CVEs did not impact on PFS or OS. Hypokalemia was associated with better median OS (p = 0.036). Similar associations were observed after stratification by subgroup. CONCLUSIONS: Median PFS and OS estimates and incidence of CVEs and hypokalemia in our series are consistent with those of pivotal trials of AA plus PDN, confirming the efficacy and safety of this regimen also in the real-world setting. Elderly patients have higher odds of developing/worsening CVEs. However, regardless of age, CVEs were not associated with worse outcomes. Treatment-related hypokalemia seemed to be associated with longer OS, albeit this finding needs confirmation within larger, prospective series.

Potential cardiac risk of immune-checkpoint blockade as anticancer treatment: What we know, what we do not know, and what we can do to prevent adverse effects.

Cancer immunotherapy has become a well-established treatment option for some cancers after the development of a family of drugs targeting the so-called immune checkpoints, such as CTLA4 and PD-1 with PD-L1. These co-receptors/ligands inhibit the activation of T-cell, thus preventing an excessive inflammatory response. Tumors exploit these pathways to induce immune tolerance to themselves. Thus, the main effect of checkpoint-blocking drugs is to awake an immune response primarily directed against cancer cells. Nonetheless, as the immune response elicited by these drugs is not completely tumor-specific, their use may actually cause several adverse effects, including adverse cardiovascular effects. In this review, we will discuss the principles and potentiality of immunotherapy for cancer treatment, the experimental and clinical data on the role of CTLA4 and PD-1 with PD-L1 as immune-checkpoints in the cancer environment and in the cardiovascular system, and strategies aimed at preventing possible cardiovascular adverse effects of immune-checkpoint blockers.

A Score-Based Approach to 18F-FDG PET Images as a Tool to Describe Metabolic Predictors of Myocardial Doxorubicin Susceptibility.

PURPOSE: To verify the capability of 18F-fluorodeoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT) to identify patients at higher risk of developing doxorubicin (DXR)-induced cardiotoxicity, using a score-based image approach. METHODS: 36 patients underwent FDG-PET/CT. These patients had shown full remission after DXR-based chemotherapy for Hodgkin's disease (DXR dose: 40-50 mg/m² per cycle), and were retrospectively enrolled. Inclusion criteria implied the presence of both pre- and post-chemotherapy clinical evaluation encompassing electrocardiogram (ECG) and echocardiography. Myocardial metabolism at pre-therapy PET was evaluated according to both standardized uptake value (SUV)- and score-based approaches. The capability of the score-based image assessment to predict the occurrence of cardiac toxicity with respect to SUV measurement was then evaluated. RESULTS: In contrast to the SUV-based approach, the five-point scale method does not linearly stratify the risk of the subsequent development of cardiotoxicity. However, converting the five-points scale to a dichotomic evaluation (low vs. high myocardial metabolism), FDG-PET/CT showed high diagnostic accuracy in the prediction of cardiac toxicity (specificity = 100% and sensitivity = 83.3%). In patients showing high myocardial uptake at baseline, in which the score-based method is not able to definitively exclude the occurrence of cardiac toxicity, myocardial SUV mean quantification is able to further stratify the risk between low and intermediate risk classes. CONCLUSIONS: the score-based approach to FDG-PET/CT images is a feasible method for predicting DXR-induced cardiotoxicity. This method might improve the inter-reader and inter-scanner variability, thus allowing the evaluation of FDG-PET/CT images in a multicentral setting.

Proposal for a tailored stratification at baseline and monitoring of cardiovascular effects during follow-up in chronic phase chronic myeloid leukemia patients treated with nilotinib frontline.

Nilotinib was approved for chronic myeloid leukemia patients in chronic phase or accelerated phase after resistance to imatinib or as frontline treatment. The drug, as other tyrosine kinase inhibitor has a specific safety profile with possible occurring metabolic side effects, such as increased glycaemia and cholesterol level, that may result, in predisposed patients, in an increased rate of cardiac and vascular disorders. The objectives of this paper were to focus on the optimal procedures to perform at diagnosis in order to identify patients at risk of possible events and the correct monitoring procedures in order to prevent and manage metabolic and cardiovascular adverse events. Several national haematologist and cardiologist reviewed the literature, analysed levels of evidence for each topic and, after extensive discussions presented their proposals based on current international guidelines.

Hepatosplenic T-cell lymphoma with aberrant expression of serum ß-HCG: a case report.

BACKGROUND: Peripheral T-cell lymphomas (PTCL) represent a heterogeneous group of hematologic malignancies frequently presenting at advanced stage of diagnosis. METHODS: We report a case of PTCL with an uncommon and aggressive onset with disseminated intravascular coagulation (DIC). RESULTS: Laboratory findings revealed an aberrant expression of ß subunit of human chorionic gonadotropin (ß-HCG). Other than for determination of pregnancy, ß-HCG is regularly found as a tumor marker in germ cell tumors with trophoblastic differentiation and its aberrant expression has been reported in the literature in other neoplastic conditions only in the context of case reports. CONCLUSIONS: In hematologic malignancies, ß-HCG expression has been described only in sporadic cases. Awareness of this feature could avoid diagnostic delay in such an aggressive disease.

The five "Ws" for bone pain due to the administration of granulocyte-colony stimulating factors (G-CSFs).

Granulocyte-colony stimulating factors (G-CSFs) are commonly employed in clinical practice. The most relevant adverse event of G-CSF administration is bone pain. Approximately 20% of cancer patients experienced bone pain with the administration of prophylactic daily G-CSFs (lenograstim and filgrastim). The reported incidence of bone pain in cancer patients undergoing pegfilgrastim prophylaxis ranged from 25% to 38%. In healthy donors the incidence of bone pain was higher than in cancer patients, ranging from 52% to 84%. There are four main causes of G-CSF related bone pain: bone marrow quantitative and qualitative expansion, peripheral nociceptor sensitization to nociceptive stimuli, modulation of immune function and direct effect on bone metabolism. For the prevention and treatment of bone pain occurring after or during GCSFs administration, acetaminophen and nonsteroidal anti-inflammatory agents are commonly used as first-line treatment; antihistamines, opioids and dose reduction of G-CSFs are considered as second line therapy. The only randomized clinical trial conducted for the prevention and treatment of G-CSF induced bone pain showed the efficacy of naproxen in reducing the incidence, the severity and the duration of bone pain induced by the administration of pegfilgrastim.

Cardiovascular adverse events complicating the administration of rituximab: report of two cases.

Rituximab is a murine/human chimeric monoclonal antibody directed against the CD20 antigen. It is widely used in combination with polychemotherapy regimens for the treatment of hematological disorders. There is no evidence of direct cardiotoxicity of the drug but a few cases of cardiovascular adverse events have been reported in the literature. We report on two patients affected by stage IV non-Hodgkin lymphoma with bone marrow infiltration and peripheral blood involvement who experienced cardiovascular accidents temporally related to rituximab infusion. In both cases the monoclonal antibody was administered in association with a polychemotherapy regimen but administration was postponed several days later in order to avoid severe cytokine release syndrome because of the high tumor burden. The first case concerns an episode of atrial fibrillation in a patient with a diagnosis of small B-cell lymphoma. The episode happened immediately after rituximab infusion. In the second case there was an episode of chest pain associated with fever and chills during rituximab infusion in a patient with a diagnosis of mantle cell lymphoma. In both cases we noticed an unusual correlation between symptom recurrence and the speed of rituximab infusion. Both patients presented several cardiovascular risk factors but preliminary cardiac function assessment excluded signs of heart dysfunction. The pathogenesis of cardiovascular events during rituximab infusion remains unclear. A key role might be played by cytokine release from B cells as a consequence of rituximab activity. Moreover, pre-existing silent cardiac damage could be co-responsible for the clinical manifestations we reported. We consider our clinical experience relevant because it raises an issue of good clinical practice: despite rituximab's good tolerability profile, patients with cardiovascular risk factors should undergo accurate cardiac assessment so that silent heart disease can be detected. If the suspicion of cardiac damage is high, more extensive cardiac assessment is recommended.

Weekly standard doses of rh-EPO are highly effective for the treatment of anemic patients with low-intermediate 1 risk myelodysplastic syndromes.

For more than 20 years erythropoietin (rHEPO) has largely been used to treat anemia in myelodysplastic syndromes (MDS). Early clinical trials showed erythroid responses in no more than 15-25% of patients. In the last decade, a better selection of MDS patients suitable for a therapeutic challenge with rHEPO, alone or in combination with G-CSF, allowed for an increased response-rate, averaging around 40%. More recently, an even higher percentage of responses have been obtained using higher-doses of rHEPO (up to 80,000 IU/weekly) in lower-risk MDS patients. This treatment however, especially at such high doses, is costly and not easily affordable for prolonged periods. The aim of this study was to verify if the use of "standard" doses of rHEPO could induce a satisfying response-rate with a less expensive treatment schedule in IPSS-defined "lower-risk" MDS anemic patients. From January 2005 to December 2009 a total of 55 consecutive anemic (Hb ≤ 10 g/dL) patients (29 males, 26 females, median age 78 years) with low-intermediate-1 risk MDS were treated after informed consent with rHEPO (40,000 IU once a week subcutaneously) for at least 3 months; at the end of this period, erythroid response was assessed, and responders were allowed to continue the treatment indefinitely, whereas non-responders were considered "off study". Both efficacy and safety of the treatment were recorded and evaluated. After 3 months of treatment, 36 out of 55 (65.5%) patients achieved an erythroid response to rHEPO according to IWG 2006 criteria. Higher response-rates to rHEPO were related with both lower IPSS and particularly WPSS scores. Treatment was safe, and only 1 patient had to discontinue the treatment because of unmanageable side-effects. Among the 36 responders, 28 (77%) maintained the response after a median follow-up of 46 months. Our data indicate that standard doses of rHEPO are at least as effective as higher-doses for correcting anemia in lower-risk MDS patients; in this clinical scenario, this schedule allows for a consistent reduction of costs without precluding the achievement of a durable erythroid response.
