The majority of pharmacological approaches for the treatment of solid tumors suffer from poor selectivity, thus limiting dose escalation (i.e., the doses of drug which are required to kill tumor cells cause unacceptable toxicities to normal tissues). The situation is made more dramatic by the fact that the majority of anticancer drugs accumulate preferentially in normal tissues rather than in neoplastic sites, due to the irregular vasculature and to the high interstitial pressure of solid tumors. One avenue towards the development of more efficacious and better tolerated anti-cancer drugs relies on the targeted delivery of therapeutic agents to the tumor environment, thus sparing normal tissues. Molecular markers which are selectively expressed in the stroma and in neo-vascular sites of aggressive solid tumors appear to be particularly suited for ligand-based tumor targeting strategies. Tumor blood vessels are accessible to agents coming from the bloodstream, and their occlusion may result in an avalanche of tumor cell death. Furthermore, endothelial cells and stromal cells are genetically more stable than tumor cells and can produce abundant markers, which are ideally suited for tumor targeting strategies. This review focuses on recent advances in the development of ligands for the selective targeting of tumor blood vessels and new blood vessels in other angiogenesis-related diseases.

Purpose: Patient-controlled analgesia (PCA) has been considered for managing cancer pain; however, limited research has been conducted on optimizing continuous infusion rates with PCA. This study aimed to evaluate the efficacy and safety of a method that optimizes background infusion (BI) alongside PCA for titrating intravenous (IV) morphine in managing cancer-related pain.
Methods: Forty-four patients with solid tumors who could not manage pain with oral or transdermal opioid analgesics were randomly assigned in a 1:1 ratio to receive IV morphine through PCA or the conventional method.

Purpose: The demographic transition toward aging heralds an increase in the number of geriatric patients with cancer in India. Comprehensive geriatric assessment (CGA) is a sine qua non for treatment planning and shared decision making in these patients. We aimed to study the prevalence of malnutrition and the associated risk factors in geriatric patients with solid organ cancer.

Multiple immune components in the complex and heterogeneous tumor-immune microenvironment (TIME) work cooperatively to promote or impede cancer immunotherapy. Synergistically co-managing multiple immune cells with single agents for advanced antitumor immunity remains desirable but challenging. This In Focus article introduces a triple orthogonal linker (T-Linker)-based multimodal targeting chimera (Multi-TAC) platform, enabling the single-agent-mediated tumor-targeted co-engagement of multiple immune cell types within TIME for potentiated immunotherapy.

Hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for patients with hematologic malignancies and certain solid tumors and nonmalignant hematologic conditions. Both acute kidney injury (AKI) and chronic kidney disease (CKD) occur commonly after HSCT and are associated with significant morbidity and mortality. AKI and CKD in this setting may result from direct effects of the transplant or be caused by pretransplant bone marrow conditioning regimens and/or nephrotoxic agents administered in the post-transplant period.

Importance: Although differences in the prevalence of key cancer-specific somatic mutations as a function of genetic ancestry among patients with cancer has been well-established, few studies have addressed the practical clinical implications of these differences for the growing number of biomarker-driven treatments.
Objective: To determine if the approval of precision oncology therapies has benefited patients with cancer from various ancestral backgrounds equally over time.
Design, Setting, And Participants: A retrospective analysis of samples from patients with solid cancers who underwent clinical sequencing using the integrated mutation profiling of actionable cancer targets (MSK-IMPACT) assay between January 2014 and December 2022 was carried out.
