Muscle-invasive bladder cancer (MIBC) presents significant treatment challenges. Antibody-drug conjugates (ADCs) targeting HER2, TROP-2, and NECTIN4 offer promising therapeutic options. This study examined the spatial expression of in MIBC metastases, their association with molecular subtypes, clinical outcomes. Formalin-fixed, paraffin-embedded (FFPE) tissue samples from 251 patients were analyzed using immunohistochemistry microarrays (TMA). Expression patterns between tumor front (TF) center (TC) compared, statistical analyses assessed associations subtypes parameters. Additionally, 67 matched lymph node metastases a secondary cohort comprising 16 distant including seven primary tumors, to explore advanced stages. In HER2 was predominantly negative (83%) but showed higher positivity TC. TROP-2 exhibited high overall (58% score 3+), while displayed heterogeneity stronger Spatial overexpression at relative associated better disease free survival. Accurate assessment required four biopsies for three TROP-2. urothelial-like genomically unstable whereas widely expressed except mesenchymal-like subtype. absence staining basal, mes-like Sc/Nec-like subtypes. Paired scores all markers, reduced expression. revealed considerable compared tumors. The necessitates multiple biopsies, particularly TC, accurate evaluation. These findings underscore need personalized strategies MIBC, considering increased risk relapse Implementing multi-biopsy approach is critical enhance diagnostic accuracy.

Single-domain antibodies (sdAbs), initially identified in camelids or sharks and commonly referred to as nanobodies VNARs, have emerged a promising alternative conventional therapeutic antibodies. These sdAbs many superior physicochemical pharmacological properties, including small size, good solubility thermostability, easier accessible epitopes, strong tissue penetration. However, the inherent challenges associated with animal origin of limit their clinical use. In recent years, various innovative humanization technologies, complementarity-determining region (CDR) grafting complete engineering fully human sdAbs, been developed mitigate potential immunogenicity issues enhance compatibility. This review provides comprehensive exploration emphasizing distinctive features progress methodologies. addition, we provide an overview developing drugs strategies based on solid tumor treatment, such sdAb-drug conjugates, multispecific sdAb-based delivery systems, cell therapy.

Cancer immunotherapy has emerged as a transformative approach in oncology, utilizing the body’s immune system to specifically target and destroy malignant cells. This review explores scope impact of various immunotherapeutic strategies, including monoclonal antibodies, chimeric antigen receptor (CAR)-T cell therapy, checkpoint inhibitors, cytokine therapeutic vaccines. Monoclonal such Rituximab Trastuzumab, have revolutionized treatment paradigms for lymphoma breast cancer by offering targeted interventions that reduce off-target effects. CAR-T therapy presents potentially curative option refractory hematologic malignancies, although challenges remain effectively treating solid tumors. Checkpoint inhibitors redefined management cancers like melanoma lung cancer; however, managing immune-related adverse events ensuring durable responses are critical areas focus. Cytokine continues play vital role modulating response, with advancements engineering improving specificity reducing systemic toxicity. Therapeutic vaccines, particularly mRNA-based represent frontier personalized treatment, aiming generate robust, long-lasting against tumor-specific antigens. Despite these advancements, field faces significant challenges, resistance, tumor heterogeneity, immunosuppressive microenvironment. Future research should address obstacles through emerging technologies, next-generation Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-based gene editing, AI-driven drug discovery. By integrating novel approaches, holds promise more durable, less toxic, highly options, ultimately patient outcomes survival rates.

Antibody-drug conjugates (ADCs) are a potent class of antineoplastic drugs that deliver cytotoxic agents via targeting with monoclonal antibodies; however, ADCs associated high rates lung toxicities, limiting the therapeutic potential in many patients. We report case patient metastatic non-small cell cancer taking ADC telisotuzumab vedotin (Teliso V) plus osimtertinib who developed ADC-induced pneumonitis despite clinical benefit. This was able to tolerate treatment for prolonged period on novel steroid regimen, using steroids when asymptomatic but radiologically evident and as daily suppressant. strategy may have implications broader management ADC-interstitial disease/pneumonitis underscores its mechanisms.
