Until recently, treatment options for patients diagnosed with Acute Myeloid Leukemia (AML) were limited and predominantly relied on various combinations, dosages, or schedules of traditional chemotherapeutic agents. Patients with advanced age, relapsed/refractory disease or comorbidities were often left without effective treatment options. Novel advances in the understanding of leukemogenesis at the molecular and genetic levels, alongside recent progress in drug development, have resulted in the emergence of novel therapeutic agents and strategies for AML patients.

Cytokine release syndrome is a serious complication of chimeric antigen receptor-T cell therapy and is triggered by excessive secretion of inflammatory cytokines by chimeric T cells which could be fatal. Following an inquiry into the molecular mechanisms orchestrating cytokine release syndrome, we hypothesize that DeltaRex-G, a tumor targeted retrovector encoding a cytocidal CCNG1 inhibitor gene, may be a viable treatment option for corticosteroid-resistant cytokine release syndrome. DeltaRex-G received United States Food and Drug Administration Emergency Use Authorization to treat Covid-19-induced acute respiratory distress syndrome, which is due to hyperactivated immune cells.

Objective: Overall treatment time (OTT) is an important index for local control in patients with locally advanced‌ cervical cancer treated with definitive chemoradiation (External Beam Radiation Therapy (EBRT), Brachytherapy (BT) and concomittant chemotherapy). This study aimed to evaluate the efficiency and safety of reducing OTT by shortening the brachytherapy duration to one week in the intervention group copared to three weeks in the control group.

Method: The study was a non-randomized open-label phase II clinical trial, carried out on 49 cervical cancer patients (26 in intervention grouop and 23 in control group) who received EBRT concomitant with Cisplatin, followed by brachytherap in order to deliver 60 Gy  equivalent total doses in 2-Gy fractions (EQD2) to Intermediate Risk-Clinical Tumor Volume (IR-CTV) and 85-90 Gy EQD2 to High Risk-Clinical Tumor Volume (HR-CTV).

In addressing the challenges of lung cancer, attention has increasingly turned to molecular diagnostics and targeted therapies, with nucleolin (NCL) assuming a pivotal role, especially in non-small cell lung cancer. The aberrant activity and cellular distribution of NCL act as crucial biomarkers for early detection and treatment monitoring, showing a strong correlation with disease progression and patient prognosis. Elevated NCL levels signal advanced disease and poorer outcomes, underscoring its significance in evaluating disease severity and therapeutic response.

Over the past decade, ultrasound (US) has gathered significant attention and research focus in the realm of medical treatments, particularly within the domain of anti-cancer therapies. This growing interest can be attributed to its non-invasive nature, precision in delivery, availability, and safety. While the conventional objective of US-based treatments to treat breast, prostate, and liver cancer is the ablation of target tissues, the introduction of the concept of immunogenic cell death (ICD) has made clear that inducing cell death can take different non-binary pathways through the activation of the patient's anti-tumor immunity.
