Early Response Assessment in Advanced Stage Melanoma Treated with Combination Ipilimumab/Nivolumab.

BackgroundStandard combination ipilimumab/nivolumab (I/N) is given as 4 induction doses for advanced stage melanoma followed by nivolumab single-agent maintenance therapy. While many patients receive less than 4 doses due to immune-related toxicities, it is unclear if fewer doses of I/N may still provide long term clinical benefit. Our aim is to determine if response assessment after 1 or 2 doses of I/N can predict long-term survival and assess if fewer doses of I/N can lead to similar survival outcomes.MethodsWe performed a retrospective analysis on a cohort of patients with advanced melanoma

Atherosclerosis and the Bidirectional Relationship Between Cancer and Cardiovascular Disease: From Bench to Bedside, Part 2 Management.

The first part of this review highlighted the evolving landscape of atherosclerosis, noting emerging cardiometabolic risk factors, the growing impact of exposomes, and social determinants of health. The prominent role of atherosclerosis in the bidirectional relationship between cardiovascular disease and cancer was also discussed. In this second part, we examine the complex interplay between multimorbid cardio-oncologic patients, cardiometabolic risk factors, and the harmful environments that lend a "syndemic" nature to these chronic diseases. We summarize management strategies targeting disor

'Lessons learned' from trialists who adapted a complex intervention for remote delivery within a trial as a result of the COVID-19 pandemic: a scoping review.

BackgroundDuring the COVID-19 pandemic, complex interventions being evaluated in randomised controlled trials were often rapidly adapted from in-person to remote delivery. Such adaptations to intervention delivery have the potential to cause unintended consequences and affect important aspects of trial generalisability and interpretation. This scoping review aimed to identify the 'lessons learned' from trialists who adapted and remotely delivered a complex intervention within a trial because of the COVID-19 pandemic. Gaining a better understanding of trialists' experiences of adapting interven

Serum neurofilament light chain (sNFL) as a predictive biomarker for Chemotherapy-induced peripheral neurotoxicity (CIPN): consideration of current evidence, validation steps, and barriers to CIPN biomarker implementation in clinical practice-a narrative review.

PurposeSeveral anticancer drugs can cause chemotherapy-induced peripheral neurotoxicity (CIPN) in approximately 70% of patients; of these, 30% continue to have chronic symptoms hampering quality of life. As more people live with and beyond cancer therapy, it is becoming increasingly important for clinicians to assess those at higher risk of CIPN and provide care for managing CIPN severity. Biomarkers could be appropriate in this regard. However, an initial step towards biomarker-informed care is to advance scientific knowledge regarding the potential of current biomarkers such as neurofilament

Monitoring high-risk patients for chemotherapy-related cardiotoxicity: A retrospective analysis.

BACKGROUND: Cancer incidence remains a global challenge. The World Health Organization reported 19976499 new cases in 2022, including 1551060 in Latin America and the Caribbean. While chemotherapy advances have improved survival, these treatments carry significant risks, particularly cardiovascular complications impacting morbidity and mortality. Early cardiotoxicity detection enables targeted interventions, guiding clinical decisions on treatment adjustments to mitigate damage and preserve function. Cardiac imaging and biomarkers assess cardiotoxicity before, during, and after therapy. Despit

Studies to Assess the Utility of Serum Neurofilament Light Chain as a Biomarker in Chemotherapy-Induced Peripheral Neuropathy.

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common and disabling dose-limiting toxicities of chemotherapy. We report here the results of two separate non-interventional studies (49 patients), which evaluated blood neurofilament light chain (NfL) as a biomarker of CIPN in breast cancer patients treated with paclitaxel. All patients underwent a standard treatment protocol that was established independently of the present studies. NfL was measured in serum using an ultrasensitive single-molecule array and compared with the self-administered European Organization for Resea

Higher Incidence of Diabetes in Cancer Patients Compared to Cancer-Free Population Controls: A Systematic Review and Meta-Analysis.

Background: Diabetes increases the risk of certain types of cancer. However, the literature regarding the incidence of diabetes after cancer diagnosis is inconsistent. We aimed to assess whether there was a higher incidence of diabetes among cancer patients by performing a systematic review and meta-analysis of results from cohort studies. Methods: A systematic electronic literature search was carried out from cohort studies regarding the incidence of diabetes in cancer patients, using the databases PubMed (MEDLINE), Embase, Web of Science, and the Cochrane Library.

Chimeric Antigen Receptors Based on Low Affinity Mutants of FcεRI Re-direct T Cell Specificity to Cells Expressing Membrane IgE.

IgE is the key mediator of allergic responses. Omalizumab, an IgE-specific monoclonal antibody that depletes IgE, is effective for treating severe allergic asthma. The need for frequent administration of the expensive drug, however, limits its applications. Taking advantage of T cell memory, adoptive T cell therapy (ACT) targeting IgE-producing cells has the potential to achieve long-term suppression of IgE and relief of symptoms for severe allergic diseases. The transmembrane form of IgE (mIgE), which is present on all IgE-producing cells, serves as an excellent molecular target for ACT that

Mechanisms of T-cell Depletion in Tumors and Advances in Clinical Research.

T lymphocytes (T cells) are essential components of the adaptive immune system that play a vital role in identifying and eliminating infected and tumor cells. In tumor immunotherapy, T cells have emerged as a promising therapeutic strategy due to their high specificity, potent cytotoxic capability, long-lasting immune memory, and adaptability within immunotherapeutic approaches. However, tumors can evade the immune system by depleting T cells through various mechanisms, such as inhibitory receptor signaling, metabolic exhaustion, and physical barriers within the tumor microenvironment. This re

Influence and Role of Regulatory B Cells in Organ Transplantation: The State of the Art, Prospects, and Emerging Insights.

B cells have attracted increasing interest in the field of organ transplantation due to their newly discovered immunoregulatory properties in alloimmune responses. Traditionally, B cells have been primarily associated with adaptive immunity to foreign substances and alloreactive immune response to allografts, differentiating into antibody-producing plasma cells or memory cells upon antigen recognition and T cell collaboration. However, the existence of B cells with regulatory functions (Bregs) in humans has been widely confirmed, highlighting the presence of this subset, which has immunosuppre

Cordycepin Sensitizes Cholangiocarcinoma Cells to Be Killed by Natural Killer-92 (NK-92) Cells.

Immunotherapy harnessing immune functions is a promising strategy for cancer treatment. Tumor sensitization is one approach to enhance tumor cell susceptibility to immune cell cytotoxicity that can be used in combination with immunotherapy to achieve therapeutic efficiency. Cordycepin, a bioactive compound that can be extracted from some Cordyceps spp. has been reported to effectively inhibit tumor growth, however, the mechanism of its tumor sensitization activity that enhances immune cell cytotoxicity is unknown. In the present study, we investigated the potency of cordycepin to sensitize a l

CS-6-induced p62 accumulation exacerbates DNA damage in colorectal cancer.

BACKGROUND: Gamabufotalin (CS-6), a bufadienolide derived from Chansu, has been reported to exhibit anti-tumor effects in various cancers, including glioblastoma, nonsmall cell lung cancer, and breast cancer. However,its role in colorectal cancer (CRC) remains unexplored. OBJECTIVE: Our study aimed to evaluate the inhibition of CS-6 to CRC cells by cell viability assay, colony formation assay, comet assay, and cell cycle analysis firstly.

GPER1 Активация Антитуморной активности в Множестве миелом.

G белковый рецептор эстрогена. 1 Активация (GPER1) становится перспективной терапевтической стратегией борьбы с различными видами рака. Несмотря на то, что в контексте твердых опухолей широко изучался вопрос о адресации GPER, его воздействие на гематологию еще предстоит понять в полной мере. Здесь мы показываем, что GPER1 mRNA понижается в плазменных клетках от открытой множественной миэломы (MM) и лейкемии от плазмы по сравнению с нормальными спонсорами или преднасыщенными условиями (моноклональная гаммопатия неопределённого значения и удушающая MM); кроме того, более низкое выражение GPER1 а

Cold Atmospheric Plasma in the Treatment of Osteosarcoma.

Human osteosarcoma (OS) is the most common primary malignant bone tumor occurring most commonly in adolescents and young adults. Major improvements in disease-free survival have been achieved by implementing a combination therapy consisting of radical surgical resection of the tumor and systemic multi-agent chemotherapy. However, long-term survival remains poor, so novel targeted therapies to improve outcomes for patients with osteosarcoma remains an area of active research. This includes immunotherapy, photodynamic therapy, or treatment with nanoparticles. Cold atmospheric plasma (CAP), a hig

DNA-demethylating and anti-tumor activity of synthetic miR-29b mimics in multiple myeloma.

Aberrant DNA methylation plays a relevant role in multiple myeloma (MM) pathogenesis. MicroRNAs (miRNAs) are a class of small non-coding RNAs that recently emerged as master regulator of gene expression by targeting protein-coding mRNAs. However, miRNAs involvement in the regulation of the epigenetic machinery and their potential use as therapeutics in MM remain to be investigated. Here, we provide evidence that the expression of de novo DNA methyltransferases (DNMTs) is deregulated in MM cells. Moreover, we show that miR-29b targets DNMT3A and DNMT3B mRNAs and reduces global DNA methylation i

Oncolytic virotherapy as emerging immunotherapeutic modality: potential of parvovirus h-1.

Human tumors develop multiple strategies to evade recognition and efficient suppression by the immune system. Therefore, a variety of immunotherapeutic strategies have been developed to reactivate and reorganize the human immune system. The recent development of new antibodies against immune check points may help to overcome the immune silencing induced by human tumors. Some of these antibodies have already been approved for treatment of various solid tumor entities. Interestingly, targeting antibodies may be combined with standard chemotherapy or radiation protocols. Furthermore, recent evide
