Objective: This study was to explore the clinical role of serum trophoblast cell surface protein 2 (TROP2) antibody in patients with non-small-cell lung cancer (NSCLC).

Materials And Methods: We collected serum specimens from 117 NSCLC patients, 40 benign lung disease patients, and 60 healthy controls. TROP2 antibody concentrations were measured using enzyme-linked immunosorbent assay.

Results: Serum TROP2 antibody levels were higher in the NSCLC group compared to the control group (p < 0.001). TROP2 antibody, at a cutoff value of 9.8 U/ml, showed good diagnostic performance for NSCLC.

Conclusion: Measurement of TROP2 antibody might have diagnostic value for patients with NSCLC.

: This study evaluated the prognostic impact of Trop-2, CD47, and CD163 expression on clinical outcomes in triple-negative breast cancer (TNBC) and investigated their interactions with tumor progression. : A retrospective cohort of 92 patients with TNBC was analyzed. The expression scores for Trop-2, CD47, and CD163 were categorized as negative/low (0-3 points) or high (4-6 points).

Purpose Of Review: Antibody-drug conjugates (ADCs) are quickly becoming frontline standard of care in many tumor types, including urothelial carcinoma. This review summarizes recent clinical investigations into the use of ADCs targeting nectin-4, trophoblast cell surface antigen-2 (Trop-2), human epidermal growth factor receptor 2 (HER-2), and other antigens in urothelial carcinoma.

Recent Findings: This review covers efficacy and toxicity data of ADCs alone and in combination with immunotherapy; mechanisms of resistance; and preclinical studies that provide biological basis for clinical approaches.

Purpose: Recent clinical advances with the approval of antibody-drug conjugates targeting Trop-2 such as sacituzumab-govitecan and datopotomab-deruxtecan have garnered tremendous interest for their therapeutic efficacy in numerous tumor types including breast and lung cancers. ImmunoPET can stratify tumor avidity, clarifying patient eligibility for ADC therapy as well as a diagnostic companion during therapy. Slow antibody circulation requires days to reach optimal imaging timepoints.

Targeted therapy with antibody-drug conjugates (ADCs) has shown promising results in the treatment of various solid tumours. Sacituzumab-govitecan (SG), a humanised anti-Trop2 monoclonal antibody in combination with the cytotoxic topoisomerase I inhibitor SN38, has been approved for the treatment of metastatic triple-negative breast cancer. The treatment approach with SG requires the expression of Trop2 in the tumour cells.

Hydrophobic payloads incorporated into antibody-drug conjugates (ADCs) typically are superior to hydrophilic ones in tumor penetration and "bystander killing" upon release from ADCs. However, they are prone to aggregation and accelerated plasma clearance, which lead to reduced efficacies and increased toxicities of ADC molecules. Shielding the hydrophobicity of payloads by incorporating polyethylene glycol (PEG) elements or sugar groups into the ADC linkers has emerged as a viable alternative to directly adopting hydrophilic payloads.
