Anthracycline-Induced Cardiomyopathy in Cancer Survivors: Management and Long-Term Implications.

Recent advancements in personalized treatments, such as anthracycline chemotherapy, coupled with timely diagnoses, have contributed to a decrease in cancer-specific mortality rates and an improvement in cancer prognosis. Anthracyclines, a potent class of antibiotics, are extensively used as anticancer medications to treat a broad spectrum of tumors. Despite these advancements, a considerable number of cancer survivors face increased risks of treatment complications, particularly the cardiotoxic effects of chemotherapeutic drugs like anthracyclines. These effects can range from subclinical manifestations to severe consequences such as irreversible heart failure and death, highlighting the need for effective management of chemotherapy side effects for improved cancer care outcomes. Given the lack of specific treatments, early detection of subclinical cardiac events post-anthracycline therapy and the implementation of preventive strategies are vital. An interdisciplinary approach involving cardiovascular teams is crucial for the prevention and efficient management of anthracycline-induced cardiotoxicity. Various factors, such as age, gender, duration of treatment, and comorbidities, should be considered significant risk factors for developing chemotherapy-related cardiotoxicity. Tools such as electrocardiography, echocardiography, nuclear imaging, magnetic resonance imaging, histopathologic evaluations, and serum biomarkers should be appropriately used for the early detection of anthracycline-related cardiotoxicity. Furthermore, understanding the underlying biological mechanisms is key to developing preventive measures and personalized treatment strategies to mitigate anthracycline-induced cardiotoxicity. Exploring specific cardiotoxic mechanisms and identifying genetic variations can offer fresh perspectives on innovative, personalized treatments. This chapter aims to discuss cardiomyopathy following anthracycline therapy, with a focus on molecular mechanisms, preventive strategies, and emerging treatments.

Risk of Venous Thromboembolism in Patients With Stage III and IV Non-Small-Cell Lung Cancer: Nationwide Descriptive Cohort Study.

BACKGROUND: Venous thromboembolism (VTE) is a common complication in patients starting cancer therapies for non-small-cell lung cancer (NSCLC). We examined the risk and timing of VTE in patients with stage IIIA, IIIB to C, and stage IV NSCLC according to received cancer treatments. MATERIALS AND METHODS: A nationwide registry-based cohort study of patients recorded in the Danish Lung Cancer Registry (2010-2021) followed for 1 year after entry into the registry to assess the incidence of VTE. The Aalen-Johansen estimator was used to calculate the risk of VTE after treatment commencement with chemotherapy, radiotherapy, chemoradiation, immunotherapy, and targeted therapy. RESULTS: Among the 3475 patients with stage IIIA, 4047 with stage IIIB to C, and 18,082 patients with stage IV cancer, the 1-year risk of VTE was highest in the first 6 months and varied markedly by cancer stage and cancer treatment. In stage IIIA, VTE risk was highest with chemotherapy (3.9%) and chemoradiation (4.1%). In stage IIIB to C, risks increased with chemotherapy (5.2%), immunotherapy (9.4%), and targeted therapy (6.0%). Stage IV NSCLC showed high risk with targeted therapy (12.5%) and immunotherapy (12.2%). The risk was consistently higher for pulmonary embolism than deep vein thrombosis. CONCLUSION: VTE risks vary substantially according to cancer treatments and cancer stages. The highest risk was observed in the initial 6 months of therapy initiation. These insights emphasize the need for tailored risk assessment and vigilance in managing VTE complications in patients with NSCLC. Further research is needed to optimize individual thromboprophylaxis strategies for patients with unresectable and metastatic NSCLC.

Antineoplastic therapy is an independent risk factor for dental caries in childhood cancer patients: a retrospective cohort study.

PURPOSE: To evaluate the antineoplastic therapy (AT) as a risk factor for dental caries lesions independent of other risk factors such as income, family education, stimulated salivary flow rate, hygiene habits, frequency of sugar intake, and microbiota in childhood cancer (CC) patients. METHODS: 72 individuals were divided into CC patients (n=36) and healthy individuals (control group - CT n=36). Demographic data, hygiene habits, frequency of sugar intake, CC type, and AT were collected. Stimulated salivary flow rate was measured and the presence and concentration of Streptococcus mutans were assessed using a real-time polymerase chain reaction (qPCR) technique. Clinical evaluations included plaque index (PI) and decayed-missing-filled-teeth index (dmft/DMFT). Descriptive statistics, T-test, Mann-Whitney test, chi-square test, Fisher's exact test, and two-way analysis of variance were used for data analysis (p<0.05). RESULTS: At the time of oral evaluation, both groups exhibited similar ages with means of 12.0±3.9 years old for CC and 12.0±4.0 years old for CT patients. All CC patients underwent chemotherapy with nine also undergoing radiotherapy. Significant differences were observed between the groups in terms of color/race, income, family education, and hygiene habits. However, no statistically significant differences were found between groups regarding the frequency of sugar intake, stimulated salivary flow rate, or the concentration of Streptococcus mutans (qPCR technique). For clinical parameters, the DMF (CC:1.80, CT: 0.75), decayed (CC: 0.88, CT: 0.19), missing (CC: 0.25, CT:0), and PI (CC: 30.5%, CT: 22.6%) were higher in the CC group (p<0.05). CONCLUSION: Childhood cancer (CC) patients undergoing antineoplastic therapy (AT) exhibit a higher prevalence of dental caries, regardless of income/education, frequency of sugar intake, stimulated salivary flow rate, and microbiota.

eviQ Cancer Treatments Online: Providing evidence-based information to improve cancer patient outcomes.

AIM: To understand the current usage of eviQ Cancer Treatments Online (www.eviQ.org.au), an Australian, open-access website providing evidence-based and consensus-driven cancer treatment protocols and information, and the extent to which it is meeting its intended outcomes and providing value to its users. METHODS: A mixed-method evaluation was conducted in 2020-2022 which included a review of key program documentation and website usage data, and delivery of a focused online survey to its users. RESULTS: In 2022, 329 clinicians representing all Australian states and territories contributed to eviQ content development and review. eviQ content continues to grow with a 15.2% increase in total content from 2019 to 2022.  eviQ website users continue to grow with 90,000 total monthly users in 2022, representing a 166% increase from 2018. The proportion of international users compared to Australian users continues to grow with 57% of total users in Australia and 43% international in 2022. Of 466 survey responses, the most cited reason for eviQ use was for information on side effects/toxicity (67%). Ninety-three percent (93%) of respondents either agreed or strongly agreed that eviQ contributed to both health professionals providing the best evidence-based treatment and care and improving the standardization of treatment and care provided. CONCLUSION:  eviQ is embedded in Australian clinical practice, highly valued, and relied upon by users. Users agree that eviQ has a positive impact on patients by supporting the delivery of evidence-based treatment and that eviQ contributed to patients' improved health outcomes and quality of life. eviQ's increasing international usage should be explored.

Paradigm Shift: A Comprehensive Review of Ovarian Cancer Management in an Era of Advancements.

Ovarian cancer (OC) is the female genital malignancy with the highest lethality. Patients present a poor prognosis mainly due to the late clinical presentation allied with the common acquisition of chemoresistance and a high rate of tumour recurrence. Effective screening, accurate diagnosis, and personalised multidisciplinary treatments are crucial for improving patients' survival and quality of life. This comprehensive narrative review aims to describe the current knowledge on the aetiology, prevention, diagnosis, and treatment of OC, highlighting the latest significant advancements and future directions. Traditionally, OC treatment involves the combination of cytoreductive surgery and platinum-based chemotherapy. Although more therapeutical approaches have been developed, the lack of established predictive biomarkers to guide disease management has led to only marginal improvements in progression-free survival (PFS) while patients face an increasing level of toxicity. Fortunately, because of a better overall understanding of ovarian tumourigenesis and advancements in the disease's (epi)genetic and molecular profiling, a paradigm shift has emerged with the identification of new disease biomarkers and the proposal of targeted therapeutic approaches to postpone disease recurrence and decrease side effects, while increasing patients' survival. Despite this progress, several challenges in disease management, including disease heterogeneity and drug resistance, still need to be overcome.

Patient Priorities Concerning Treatment Decisions for Advanced Neuroendocrine Tumors Identified by Discrete Choice Experiments.

BACKGROUND: Patients with advanced neuroendocrine tumors (NETs) have multiple treatment options. Ideally, treatment decisions are shared between physician and patient; however, previous studies suggest that oncologists and patients place different value on treatment attributes such as adverse event (AE) rates. High-quality information on NET patient treatment preferences may facilitate patient-centered decision making by helping clinicians understand patient priorities. METHODS: This study used 2 discrete choice experiments (DCE) to elicit preferences of NET patients regarding advanced midgut and pancreatic NET (pNET) treatments. The DCEs used the "potentially all pairwise rankings of all possible alternatives" (PAPRIKA) method. The primary objective was to determine relative utility rankings for treatment attributes, including progression-free survival (PFS), treatment modality, and AE rates. Ranking of attribute profiles matching specific treatments was also determined. Levels for treatment attributes were obtained from randomized clinical trial data of NET treatments. RESULTS: One hundred and 10 participants completed the midgut NET DCE, and 132 completed the pNET DCE. Longer PFS was the highest ranked treatment attribute in 64.5% of participants in the midgut NET DCE, and in 59% in the pNET DCE. Approximately, 40% of participants in both scenarios prioritized lower AE rates or less invasive treatment modalities over PFS. Ranking of treatment profiles in the midgut NET scenario identified 60.9% of participants favoring peptide receptor radionuclide therapy (PRRT), and 30.0% somatostatin analogue dose escalation. CONCLUSION: NET patients have heterogeneous priorities when choosing between treatment options based on the results of 2 independent DCEs. These results highlight the importance of shared decision making for NET patients.

Prevalence of anticipatory nausea and vomiting in breast cancer patients undergoing highly emetogenic chemotherapy

SUMMARY OBJECTIVE: Anticipatory nausea and vomiting are unpleasant symptoms observed before undergoing chemotherapy sessions. Less is known about the occurrence of symptoms since the advent of the new neurokinin-1 antagonist. METHODS: This prospective cohort study was performed at a single Brazilian Institution. This study included breast cancer patients who received doxorubicin and cyclophosphamide chemotherapy and an appropriate antiemetic regimen (dexamethasone 10 mg, palonosetron 0.56 mg, and netupitant 300 mg in the D1 followed by dexamethasone 10 mg 12/12 h in D2 and D4). Patients used a diary to record nausea, vomiting, and use of rescue medication in the first two cycles of treatment. The prevalence of anticipatory nausea and vomiting was assessed before chemotherapy on day 1 of C2. RESULTS: From August 4, 2020, to August 12, 2021, 60 patients were screened, and 52 patients were enrolled. The mean age was 50.8 (28-69) years, most had stage III (53.8%), and most received chemotherapy with curative intent (94%). During the first cycle, the frequency of overall nausea and vomiting was 67.31%, and that of severe nausea and vomiting (defined as grade>4 on a 10-point visual scale or use of rescue medication) was 55.77%. Ten patients had anticipatory nausea and vomiting (19.23%). The occurrence of nausea and vomiting during C1 was the only statistically significant predictor of anticipatory nausea and vomiting (OR=16, 95%CI 2.4-670.9, p=0.0003). CONCLUSION: The prevalence of anticipatory nausea is still high in the era of neurokinin-1 antagonists, and failure of antiemetic control in C1 remains the main risk factor. All efforts should be made to control chemotherapy-induced nausea or nausea and vomiting on C1 to avoid anticipatory nausea.

Single-cell RNA-sequencing atlas reveals an FABP1-dependent immunosuppressive environment in hepatocellular carcinoma.

BACKGROUND: Single-cell RNA sequencing, also known as scRNA-seq, is a method profiling cell populations on an individual cell basis. It is particularly useful for more deeply understanding cell behavior in a complicated tumor microenvironment. Although several previous studies have examined scRNA-seq for hepatocellular carcinoma (HCC) tissues, no one has tested and analyzed HCC with different stages. METHODS: In this investigation, immune cells isolated from surrounding normal tissues and cancer tissues from 3 II-stage and 4 III-stage HCC cases were subjected to deep scRNA-seq. The analysis included 15 samples. We distinguished developmentally relevant trajectories, unique immune cell subtypes, and enriched pathways regarding differential genes. Western blot and co-immunoprecipitation were performed to demonstrate the interaction between fatty acid binding protein 1 (FABP1) and peroxisome proliferator-activated receptor gamma(PPARG). In vivo experiments were performed in a C57BL/6 mouse model of HCC established via subcutaneous injection. RESULTS: FABP1 was discovered to be overexpressed in tumor-associated macrophages (TAMs) with III-stage HCC tissues compared with II-stage HCC tissues. This finding was fully supported by immunofluorescence detection in significant amounts of HCC human samples. FABP1 deficiency in TAMs inhibited HCC progression in vitro. Mechanistically, FABP1 interacted with PPARG/CD36 in TAMs to increase fatty acid oxidation in HCC. When compared with C57BL/6 mice of the wild type, tumors in FABP1-/- mice consistently showed attenuation. The FABP1-/- group's relative proportion of regulatory T cells and natural killer cells showed a downward trend, while dendritic cells, M1 macrophages, and B cells showed an upward trend, according to the results of mass cytometry. In further clinical translation, we found that orlistat significantly inhibited FABP1 activity, while the combination of anti-programmed cell death 1(PD-1) could synergistically treat HCC progression. Liposomes loaded with orlistat and connected with IR780 probe could further enhance the therapeutic effect of orlistat and visualize drug metabolism in vivo. CONCLUSIONS: ScRNA-seq atlas revealed an FABP1-dependent immunosuppressive environment in HCC. Orlistat significantly inhibited FABP1 activity, while the combination of anti-PD-1 could synergistically treat HCC progression. This study identified new treatment targets and strategies for HCC progression, contributing to patients with advanced HCC from new perspectives.

Antineoplastic therapy in childhood cancer patients presents a negative impact in the periodontal tissues: a cohort study.

OBJECTIVES: To investigate the effect of antineoplastic therapy (AT) in the periodontal tissues of childhood cancer (CC) patients. MATERIALS AND METHODS: Seventy-two individuals were divided into CC (n=36) and healthy individuals (control group-CG, n=36). Demographics, hygiene habits, CC type, and AT were collected. Salivary flow and the presence and concentration of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Fusobacterium nucleatum were analyzed. Clinical evaluation included plaque (PI) and gingival indexes (GI), periodontal probing depth (PPD), and clinical attachment level (CAL). Patients were classified into periodontal health, gingivitis, or periodontitis. Descriptive statistics, T test, Mann-Whitney test, chi-square, Fisher's exact test, and two-way analysis of variance were used (p<0.05). RESULTS: The mean age of the patients was similar (CC 12.0±3.9 years and CG 12.0±4.0 years). In the CC group, all patients underwent chemotherapy and nine radiotherapy. Color/race, income, and family education showed significant differences between groups. There was no difference between groups in salivary flow. Higher levels of Fusobacterium nucleatum were seen in CC (p=0.02). Significant difference between groups was found for PI (CC: 30.5%, CG: 22.6%), GI (CC: 28.8%, CG: 17.3%), PPD (CC: 1.77 mm, CG: 1.61 mm), and CAL (CC: 1.77 mm, CG: 1.57 mm), periodontal health (CC: 3, CG: 7), gingivitis (CC: 16, CG: 24), or periodontitis (CC: 17, CG: 5). CONCLUSION: AT in CC patients presents a negative impact in the periodontal and microbiological parameters. CLINICAL RELEVANCE: Childhood cancer individuals showed worse periodontal parameters and higher levels of Fusobacterium nucleatum in the saliva when compared to healthy individuals.

Oncolytic virotherapy with intratumoral injection of vaccinia virus TG6002 and 5-fluorocytosine administration in dogs with malignant tumors.

TG6002 is an oncolytic vaccinia virus expressing FCU1 protein, which converts 5-fluorocytosine into 5-fluorouracil. The study objectives were to assess tolerance, viral replication, 5-fluorouracil synthesis, and tumor microenvironment modifications to treatment in dogs with spontaneous malignant tumors. Thirteen dogs received one to three weekly intratumoral injections of TG6002 and 5-fluorocytosine. The viral genome was assessed in blood and tumor biopsies by qPCR. 5-Fluorouracil concentrations were measured in serum and tumor biopsies by liquid chromatography or high-resolution mass spectrometry. Histological and immunohistochemical analyses were performed. The viral genome was detected in blood (7/13) and tumor biopsies (4/11). Viral replication was suspected in 6/13 dogs. The median intratumoral concentration of 5-fluorouracil was 314 pg/mg. 5-Fluorouracil was not detected in the blood. An increase in necrosis (6/9) and a downregulation of intratumoral regulatory T lymphocytes (6/6) were observed. Viral replication, 5-fluorouracil synthesis, and tumor microenvironment changes were more frequently observed with higher TG6002 doses. This study confirmed the replicative properties, targeted chemotherapy synthesis, and reversion of the immunosuppressive tumor microenvironment in dogs with spontaneous malignant tumors treated with TG6002 and 5-fluorocytosine.

Oral hygiene protocols reduce the severity and incidence of oral mucositis during antineoplastic treatment: a systematic review and meta-analysis of randomized and non-randomized clinical trials.

OBJECTIVE: The objective of this systematic review was to determine whether oral and dental hygiene protocols (DHPs) reduce the incidence and severity of oral mucositis (OM) during antineoplastic treatment. MATERIALS AND METHODS: This PROSPERO-registered systematic review (CRD42021295322) was based on searches of publicly accessible databases, including PubMed, Scopus, Web of Science, LILACS, EBSCOhost, LIVIVO, Embase, and gray literature (Google Scholar, ProQuest, and Energy) until December 2021. Twenty-five articles from these searches and 14 articles retrieved from the references therein were evaluated in this systematic review and meta-analysis. The risk of bias (RoB) was assessed using RoB-2 and ROBINS-I for randomized (RCT) and non-randomized (n-RCT) clinical trials, respectively. A meta-analysis was performed on RCTs and n-RCTs in two subgroups to evaluate oral mouth rinses or DHP. GRADE-pro was used to assess the degree of certainty of the evidence. RESULTS: Of the 3367 articles retrieved, 25 RCTs and 14 n-RCTs involving 2109 and 754 patients, respectively, were included in the analyses. RoB was low for RCTs and moderate-to-very severe for n-RCTs. High heterogeneity and publication RoB were identified. In RCTs, mouth rinses (p = 0.830) and DHP (p = 0.100) did not reduce the incidence of OM. However, mouth rinses strongly reduced the severity of OM (p < 0.001; Cohen's d = - 1.87, 95% confidence interval [CI] = - 2.49 to - 1.24). In non-RCTs, mouth rinses (p < 0.001) and DHP (p < 0.001) reduced the relative risk of OM 0.38 (95% CI = 0.24 to 0.59) and 0.64 (95% CI = 0.53 to 0.70) times, respectively. In addition, DHP strongly reduced OM severity (Cohen's d = - 0.81, 95% CI = - 1.03 to - 0.59). GRADE-pro showed high certainty of OM severity and incidence in RCTs and non-RCTs, respectively, and low (OM incidence in RCTs) to very low (OM severity in non-RCTs) certainty in other outcomes. CONCLUSION: DHPs strongly reduce the severity and moderately reduce the incidence of OM. However, further studies with low heterogeneity are needed to validate these findings.

Equity in Cardio-Oncology Care and Research: A Scientific Statement From the American Heart Association.

Advances in cancer therapeutics have revolutionized survival outcomes in patients with cancer. However, cardiovascular toxicities associated with specific cancer therapeutics adversely affect the outcomes of patients with cancer. Recent studies have uncovered excess risks of these cardiotoxic events, especially in traditionally underrepresented populations. Despite advances in strategies to limit the risks of cardiovascular events among cancer survivors, relatively limited guidance is available to address the rapidly growing problem of disparate cardiotoxic risks among women and underrepresented patient populations. Previously decentralized and sporadic evaluations have led to a lack of consensus on the definitions, investigation, and potential optimal strategies to address disparate cardiotoxicity in contemporary cancer care (eg, with immunotherapy, biologic, or cytotoxic therapies) settings. This scientific statement aims to define the current state of evidence for disparate cardiotoxicity while proposing uniform and novel methodological approaches to inform the identification and mitigation of disparate cardio-oncology outcomes in future clinical trials, registries, and daily clinical care settings. We also propose an evidence-based integrated approach to identify and mitigate disparities in the routine clinical setting. This consensus scientific statement summarizes and clarifies available evidence while providing guidance on addressing inequities in the era of emerging anticancer therapies.

Effects of prior therapies on outcomes with trifluridine/tipiracil in patients with metastatic gastric/gastroesophageal junction cancer in a randomized phase III trial (TAGS).

BACKGROUND: In the phase III TAGS trial, trifluridine/tipiracil showed survival benefit versus placebo in patients with metastatic gastric/gastroesophageal junction cancer and ≥ 2 prior chemotherapies. This post hoc exploratory analysis assessed the impact of prior therapy type on outcomes. METHODS: Based on prior treatment, patients in TAGS (N = 507) were categorized into overlapping subgroups: ramucirumab ± other agents (n = 169), no ramucirumab (n = 338), paclitaxel but no ramucirumab (n = 136), ramucirumab + paclitaxel sequentially or in combination (n = 154), neither paclitaxel nor ramucirumab (n = 202), irinotecan (n = 281), and no irinotecan (n = 226). Overall and progression-free survival, time to Eastern Cooperative Oncology Group performance status (ECOG PS) ≥ 2, and safety were assessed. RESULTS: Baseline characteristics and prior therapy patterns were generally well balanced between trifluridine/tipiracil and placebo arms across subgroups. Trifluridine/tipiracil was associated with survival benefits versus placebo regardless of prior treatment: across subgroups, median overall survival was 4.6-6.1 versus 3.0-3.8 months (hazard ratios, 0.47-0.88), median progression-free survival was 1.9-2.3 versus 1.7-1.8 months (hazard ratios, 0.49-0.67), and median time to ECOG PS ≥ 2 was 4.0-4.7 versus 1.9-2.5 months (hazard ratios, 0.56-0.88). Among trifluridine/tipiracil-randomized patients, median overall and progression-free survival trended longer in those who had not received ramucirumab, paclitaxel and ramucirumab, or irinotecan (6.0-6.1 and 2.1-2.3 months, respectively) than in those who previously received these agents (4.6-5.7 and 1.9 months). The trifluridine/tipiracil safety profile was consistent across subgroups, with similar overall incidences of grade ≥ 3 adverse events. Minor variations in hematologic toxicities were noted. CONCLUSIONS: In TAGS, third- or later-line trifluridine/tipiracil treatment demonstrated overall and progression-free survival and functioning benefits versus placebo and a consistent safety profile in patients with metastatic gastric/gastroesophageal junction cancer, regardless of prior treatment type. CLINICAL TRIALS REGISTRATION: clinicaltrials.gov NCT02500043.

Characterization of the endotheliopathy, innate-immune activation and hemostatic imbalance underlying CAR-T cell toxicities: laboratory tools for an early and differential diagnosis.

BACKGROUND: Chimeric antigen receptor (CAR)-T cell-based immunotherapy constitutes a revolutionary advance for treatment of relapsed/refractory hematological malignancies. Nevertheless, cytokine release and immune effector cell-associated neurotoxicity syndromes are life-threatening toxicities in which the endothelium could be a pathophysiological substrate. Furthermore, differential diagnosis from sepsis, highly incident in these patients, is challenging. Suitable laboratory tools could be determinant for their appropriate management. METHODS: Sixty-two patients treated with CAR-T cell immunotherapy for hematological malignancies (n=46 with CD19-positive diseases, n=16 with multiple myeloma) were included. Plasma samples were obtained: before CAR-T cell infusion (baseline); after 24-48 hours; at suspicion of any toxicity onset and 24-48 hours after immunomodulatory treatment. Biomarkers of endothelial dysfunction (soluble vascular cell adhesion molecule 1 (sVCAM-1), soluble TNF receptor 1 (sTNFRI), thrombomodulin (TM), soluble suppression of tumorigenesis-2 factor (ST2), angiopoietin-2 (Ang-2)), innate immunity activation (neutrophil extracellular traps (NETs), soluble C5b-9 (sC5b-9)) and hemostasis/fibrinolysis (von Willebrand Factor antigen (VWF:Ag), ADAMTS-13 (A13), α2-antiplasmin (α2-AP), plasminogen activator inhibitor-1 antigen (PAI-1 Ag)) were measured and compared with those in cohorts of patients with sepsis and healthy donors. RESULTS: Patients who developed CAR-T cell toxicities presented increased levels of sVCAM-1, sTNFRI and ST2 at the clinical onset versus postinfusion values. Twenty-four hours after infusion, ST2 levels were good predictors of any CAR-T cell toxicity, and combination of ST2, Ang-2 and NETs differentiated patients requiring intensive care unit admission from those with milder clinical presentations. Association of Ang-2, NETs, sC5b-9, VWF:Ag and PAI-1 Ag showed excellent discrimination between severe CAR-T cell toxicities and sepsis. CONCLUSIONS: This study provides relevant contributions to the current knowledge of the CAR-T cell toxicities pathophysiology. Markers of endotheliopathy, innate immunity activation and hemostatic imbalance appear as potential laboratory tools for their prediction, severity and differential diagnosis.

Prognostic Impact of Ras Mutation on Surgical Strategy in Rectal Cancer Patients Undergoing Neoadjuvant Treatment.

BACKGROUND/AIM: Complete clinical response in rectal cancer after neoadjuvant chemo-radiotherapy is challenging. Indeed, indication to surgery vs. "watch and wait" is a debate due the poor predictive value of restaging exams in order to identify a pathological complete response (pCR). Improving the knowledge on mutational pathways such as MAPK/ERK could be helpful in assessing the real impact of disease on prognosis and in choosing the best therapeutic target. This study aimed to evaluate the significance of biomolecular parameters as prognostic factors in patients undergoing radical surgery after chemo-radiotherapy. PATIENTS AND METHODS: A retrospective analysis was performed including 39 patients who had undergone radical surgery after neoadjuvant chemo-radiotherapy for rectal adenocarcinoma stage II-III through additional evaluation of the following biomolecular markers on surgical specimens: exons 2, 3 and 4 of the KRAS and NRAS genes and exon 15 of BRAF by pyrosequencing. Kaplan-Meier survival curves were plotted to evaluate the association of pathologic response and RAS status with progression-free survival (PFS) and overall survival (OS). The log-rank test was used to assess statistical differences among the survival curves. RESULTS: Data analysis showed RAS mutation in 15 patients (38.46%). pCR was achieved in seven patients (18%), including only two RAS mutation cases. The distribution of evaluated variables was homogeneous in the two groups based on pathological response. The Kaplan-Meier curve showed poor outcomes in OS and PFS in patients with RAS mutation (p=0.0022 and p=0.000392, respectively), but no significant differences based on pathological response for both OS and PFS. CONCLUSION: RAS mutation seems to be related to poor prognosis and increased risk of recurrence in rectal cancer patients undergoing radical surgery after chemo-radiotherapy.

Ototoxicity prognostic models in adult and pediatric cancer patients: a rapid review.

PURPOSE: A cornerstone of treatment for many cancers is the administration of platinum-based chemotherapies and/or ionizing radiation, which can be ototoxic. An accurate ototoxicity risk assessment would be useful for counseling, treatment planning, and survivorship follow-up in patients with cancer. METHODS: This systematic review evaluated the literature on predictive models for estimating a patient's risk for chemotherapy-related auditory injury to accelerate development of computational approaches for the clinical management of ototoxicity in cancer patients. Of the 1195 articles identified in a PubMed search from 2010 forward, 15 studies met inclusion for the review. CONCLUSIONS: All but 1 study used an abstraction of the audiogram as a modeled outcome; however, specific outcome measures varied. Consistently used predictors were age, baseline hearing, cumulative cisplatin dose, and radiation dose to the cochlea. Just 5 studies were judged to have an overall low risk of bias. Future studies should attempt to minimize bias by following statistical best practices including not selecting multivariate predictors based on univariate analysis, validation in independent cohorts, and clearly reporting the management of missing and censored data. Future modeling efforts should adopt a transdisciplinary approach to define a unified set of clinical, treatment, and/or genetic risk factors. Creating a flexible model that uses a common set of predictors to forecast the full post-treatment audiogram may accelerate work in this area. Such a model could be adapted for use in counseling, treatment planning, and follow-up by audiologists and oncologists and could be incorporated into ototoxicity genetic association studies as well as clinical trials investigating otoprotective agents. IMPLICATIONS FOR CANCER SURVIVORS: Improvements in the ability to model post-treatment hearing loss can help to improve patient quality of life following cancer care. The improvements advocated for in this review should allow for the acceleration of advancements in modeling the auditory impact of these treatments to support treatment planning and patient counseling during and after care.

Medulloblastoma: Current Perspectives and Recent Advances.

Medulloblastoma is the most common embryonal tumor of the central nervous system in childhood. Combined multimodality approaches, including surgery, radiation, and chemotherapy, have improved the outcome of medulloblastoma. Advances in genomic research have shown that medulloblastoma is not a biologically or clinically discrete entity. Previously, the risk was divided according to histology, presence of metastasis, degree of resection, and age at diagnosis. Through the development of integrated genomics, new biology-based risk stratification methods have recently been proposed. It is also important to understand the genetic predisposition of patients with medulloblastoma. Therefore, treatment goal aimed to improve the survival rate with minimal additional adverse effects and reduced long-term sequelae. It is necessary to incorporate genetic findings into the standard of care, and clinical trials that reflect this need to be conducted.

The Role of Pharmacotherapy in Treatment of Meningioma: A Systematic Review.

The safety and efficacy of various pharmacotherapeutic regimens on refractory meningiomas have been the focus of investigations. We present a comprehensive review of the previous efforts and the current state of ongoing clinical trials. A PRISMA-compliant review of the MEDLINE and ClinicalTrial.gov databases of the National Library of Medicine were performed. The primary outcomes of interest for included articles were radiographic response, overall survival, progression-free survival, six-month progression-free survival, and adverse events. Overall, 34 completed trials and 27 ongoing clinical trials were eligible. Six-month progression-free survival was reported in 6-100% of patients in the completed studies. Hematological disorders were the most common adverse events. Of the ongoing clinical trials identified, nine studies are phase I clinical trials, eleven are phase II trials, two are phase I and II trials, one is phase II and III, and two trials do not have a designated phase. Currently, there is no effective chemotherapy for refractory or recurrent meningiomas. Several promising targeted agents have been developed and are currently being investigated in the hope of identifying novel therapeutic strategies for the treatment of this pathology.

Progress of diagnosis and treatment for gastrointestinal neuroendocrine neoplasms / 肿瘤研究与临床

Gastrointestinal neuroendocrine neoplasm (GI-NEN) is an important part of digestive system tumor. With the progress of diagnosis and the further understanding of GI-NEN, the diagnostic rate is increasing. However, GI-NEN is a rare tumor, thus clinicians are not familiar with the diagnosis and treatment. Misdiagnosis and missed diagnosis of GI-NEN often occur, and the treatment regimen is not standardized. In recent years, some progresses of the diagnosis and treatment have been made in GI-NEN, especially in the aspects of pathology, imaging diagnosis, radionuclide therapy, targeted therapy and immunotherapy, which have improved the diagnosis rate and efficacy for GI-NEN. This paper reviews recent literatures of GI-NEN, summarizes its epidemiology, pathological diagnosis, image diagnosis, surgery, targeted therapy, radionuclide therapy, chemotherapy, immunotherapy, and separates GI-NEN into metastatic and non-metastatic groups for detailed review to provide a reference for guiding clinical diagnosis and treatment as well as exploring the new treatment regimens of GI-NEN.
