Anthracycline-induced cardiovascular toxicity: validation of the Heart Failure Association and International Cardio-Oncology Society risk score.

BACKGROUND AND AIMS: Baseline cardiovascular toxicity risk stratification is critical in cardio-oncology. The Heart Failure Association (HFA) and International Cardio-Oncology Society (ICOS) score aims to assess this risk but lacks real-life validation. This study validates the HFA-ICOS score for anthracycline-induced cardiovascular toxicity. METHODS: Anthracycline-treated patients in the CARDIOTOX registry (NCT02039622) were stratified by the HFA-ICOS score. The primary endpoint was symptomatic or moderate to severe asymptomatic cancer therapy-related cardiac dysfunction (CTRCD), with all-cause mortality and cardiovascular mortality as secondary endpoints. RESULTS: The analysis included 1066 patients (mean age 54 ± 14 years; 81.9% women; 24.5% ≥65 years). According to the HFA-ICOS criteria, 571 patients (53.6%) were classified as low risk, 333 (31.2%) as moderate risk, 152 (14.3%) as high risk, and 10 (0.9%) as very high risk. Median follow-up was 54.8 months (interquartile range 24.6-81.8). A total of 197 patients (18.4%) died, and 718 (67.3%) developed CTRCD (symptomatic: n = 45; moderate to severe asymptomatic: n = 24; and mild asymptomatic: n = 649). Incidence rates of symptomatic or moderate to severe symptomatic CTRCD and all-cause mortality significantly increased with HFA-ICOS score [hazard ratio 28.74, 95% confidence interval (CI) 9.33-88.5; P < .001, and hazard ratio 7.43, 95% CI 3.21-17.2; P < .001) for very high-risk patients. The predictive model demonstrated good calibration (Brier score 0.04, 95% CI 0.03-0.05) and discrimination (area under the curve 0.78, 95% CI 0.70-0.82; Uno's C-statistic 0.78, 95% CI 0.71-0.84) for predicting symptomatic or severe/moderate asymptomatic CTRCD at 12 months. CONCLUSIONS: The HFA-ICOS score effectively categorizes patients by cardiovascular toxicity risk and demonstrates strong predictive ability for high-risk anthracycline-related cardiovascular toxicity and all-cause mortality.

Clinical features and lipid metabolism genes as potential biomarkers in advanced lung cancer.

BACKGROUND: Lung cancer is one of the most lethal tumors with a poor survival rate even in those patients receiving new therapies. Metabolism is considered one of the hallmarks in carcinogenesis and lipid metabolism is emerging as a significant contributor to tumor metabolic reprogramming. We previously described a profile of some lipid metabolism related genes with potential prognostic value in advanced lung cancer. AIM: To analyze clinical and pathological characteristics related to a specific metabolic lipid genomic signature from patients with advanced lung cancer and to define differential outcome. METHODS: Ninety samples from NSCLC (non-small cell lung cancer) and 61 from SCLC (small cell lung cancer) patients were obtained. We performed a survival analysis based on lipid metabolic genes expression and clinical characteristics. The primary end point of the study was the correlation between gene expression, clinical characteristics and survival. RESULTS: Clinical variables associated with overall survival (OS) in NSCLC patients were clinical stage, adenocarcinoma histology, Eastern Cooperative Oncology Group (ECOG), number and site of metastasis, plasma albumin levels and first-line treatment with platinum. As for SCLC patients, clinical variables that impacted OS were ECOG, number of metastasis locations, second-line treatment administration and Diabetes Mellitus (DM). None of them was associated with gene expression, indicating that alterations in lipid metabolism are independent molecular variables providing complementary information of lung cancer patient outcome. CONCLUSIONS: Specific clinical features as well as the expression of lipid metabolism-related genes might be potential biomarkers with differential outcomes.

Smart Sensorization Using Propositional Dynamic Logic.

The current high energy prices pose a serious challenge, especially in the domestic economy. In this respect, one of the main problems is obtaining domestic hot water. For this reason, this article develops a heating system applied to a conventional water tank in such a way as to minimize the necessary energy supply by converting it, under certain circumstances, into atmospheric. For this purpose, the domotic system has been equipped with sensors that automate the pressurization of the compartment and solenoid valves that regulate the external water supply. This design, to which different level sensors are applied, sends the information in real time to an artificial intelligence system, by means of deductive control, which recognizes the states of the system. This work shows the introduction of an extension of propositional dynamic logic in the field of energy efficiency. Thanks to this formalism, a qualitative control of the program variables is achieved by incorporating qualitative reasoning tools. On the other hand, it solves preventive maintenance systems through the early detection of faults in the installation. This research has led to the patenting of an intelligent domestic hot water system that considerably reduces energy consumption by setting disjointed heating intervals that, powered by renewable or non-renewable sources, are controlled by a propositional dynamic logic.

Immune checkpoint inhibitors in endometrial cancer.

The incidence of endometrial cancer (EC) is increasing worldwide. The prognosis for patients diagnosed with early-stage remains good, whereas for patients with recurrent or metastatic disease, the prognosis is poor and treatment options, until recently, were limited. In 2017, pembrolizumab was approved by the US Food and Drug Administration (FDA) for those patients with mistmach repair deficiency (MMRd) or high microsatellite instability (MSI-H) tumors. However, only 20-30 % of EC have MSI, and just over half of these patients benefit from treatment. In 2019, the FDA granted breakthrough therapy designation to lenvatinib in combination with pembrolizumab for the potential treatment of patients with advanced microsatellite stable EC that has progressed after treatment with at least one previous systemic therapy. It appears clear that immune check-point inhibitors will have a definite place in the management of EC, both as single agent or in combination with other targeted agents. In this review, we summarize the current evidence of immune check point blockade and the identification of potential biomarkers, beyond MSI-H or MMRd, that could help to predict response to this agents in correlation with the genomic EC subtypes.

Adjuvant chemotherapy in endometrial cancer.

The role of adjuvant chemotherapy (CT) is controversial in endometrial carcinoma (EC). Surgery alone is usually curative for women who are at a low risk of disease recurrence. The treatment of EC following surgical staging is based on the risk of relapse, which is defined by the cancer stage at diagnosis, histology of the tumor and other prognostic factors such as grade differentiation, the presence of substantial lymphovascular invasion (LVSI), or depth of myometrial invasion (MI). External beam radiotherapy (EBRT) and/or vaginal brachytherapy (VBT) improved local control and are used as adjuvant treatment for early-stage disease. The role of adjuvant CT is controversial in early-stage EC, and there is no uniform approach to the treatment of women with stage III EC or early-staged non-endometrioid EC. Available evidence did not support the indication of adjuvant CT in stage I-II endometroid EC. In those cases at higher risk of relapse, defined as grade 3 tumors with substantial (no focal) LVSI, specifically with deep MI or cervical involvement, could be considered. Adjuvant CT should be administered to stage III EC patients. When RT is indicated (extensive lymph node involvement or deep MI), sequential treatment with RT or "sandwich" regimen may be considered rather than concurrent CRT. The patients with stage IA MI or IB USC may be offered adjuvant CT alone or in combination with VBT, whereas in stage II uterine serous carcinoma patients adding EBRT may be reasonable. Management approach for patients with stage IA without MI USC who underwent a comprehensive surgery remains controversial, and surveillance alone or CT plus VBT is an appropriate option. Early-stage clear-cell carcinoma patients might not benefit for adjuvant CT, but stage III patients might benefit from the combination of CT and EBRT. Stage I-III uterine carcinosarcoma patients might be offered adjuvant CT followed by RT or as a "sandwich" régimen.

Lipid metabolism and lung cancer.

Lung cancer is currently one of the most serious health issues in developed and developing countries. There are multiple available treatment options; however survival still remains very poor. Despite metabolism alteration being one of the hallmarks described in human cancer, lipid metabolism disorders are less known. They are recently becoming more important in this setting and therefore achieving a deeper knowledge might be helpful to obtain new strategies to accurate diagnosis, estimate prognosis, and develop therapeutic agents based on bioactive compounds such as cerulenin, SCD1, ACLY inhibitors, statins, polyphenolic compounds, etc. The present paper reviews the basis of lipid metabolism in lung cancer and suggests potential biomarkers. Further investigation is crucial to improve our knowledge in this area.

Oxaliplatin induced-neuropathy in digestive tumors.

Oxaliplatin is one of the main drugs used in digestive tumors treatment. Peripheral neuropathy is a well-recognized dose-limiting toxicity of OXL. Two types of neuropathy have been described with this agent: acute or transient and chronic or persistent, with different etiology, clinical manifestations and prognosis. This paper is an exhaustive review about the main aspects of oxaliplatin induced peripheral neuropathy, focus in clinical features, treatment, prevention strategies and future approach.

Relevance of breast cancer subtypes for magnetic resonance imaging response monitoring during neoadjuvant chemotherapy.

Changes in magnetic resonance imaging (MRI) during neoadjuvant chemotherapy (NAC) have been reported as predictive of pathology outcome in triple-negative and HER2-positive breast cancer. The purpose of our study was to evaluate the relevance of breast cancer subtype for MRI response in 24 women before and during NAC in our centre. Our results show that a reduction greater than 23% is associated with a pathological complete response (pCR) in Her-2-positive and ER-negative/Her2-negative breast cancer, and suggest a trend correlation between higher ADC values and pCR in these subtypes in comparison with ER-positive/Her2-negative breast cancers. Higher proliferating tumours respond better to chemotherapy and our study suggests that changes in MRI during NAC are predictive of pCR in these breast cancer subtypes.
