Abstract

Non‑small cell lung cancer (NSCLC) is one of the most prevalent human cancers, which is known for local growth, easily migration, long‑distance invasion and reoccurrence. Targeted ultrasound (US) contrast combined with ultrasound for lung cancer diagnosis has been applied in the clinic. In the present study, a novel targeted ultrasound contrast agent containing chistosan/Fe3O4‑parceled bispecific antibody (TcBab) targeting carcino‑embryonic antigen, vascular endothelial growth factor receptor was introduced, and the diagnostic accuracy and sensitivity was investigated in patients with NSCLC. A total of 384 patients with suspected NSCLC were recruited to investigate the accuracy of TcBab‑ultrasound (TcBab‑US) and ultrasound. Results demonstrated that TcBab‑US improved sensitivity and may provide a novel protocol for diagnosing tumors in patients with suspected NSCLC at an early stage. Data analysis demonstrated that TcBab‑US diagnosed 154 suspected patients with NSCLC, whereas ultrasound only diagnosed 84 suspected patients with NSCLC out of a total of 384 patients with suspected NSCLC (P<0.01). A dosage experiment revealed that the optimal dose of TcBab was 5 mg/kg for NSCLC patients. Pharmacodynamics analysis showed that TcBab may be metabolized within 16 h in serum of patients. Notably, early diagnosis determined by TcBab‑US contributed to improvement of survival for NSCLC patients as determined by a comparison of the survival rate with the survival rate of patients who did not receive TcBab (P<0.05). In conclusion, these investigations suggested that TcBab improves the accuracy and diagnostic confidence of ultrasonic for the diagnosis of early‑stage NSCLC, and may have potential application value in the clinic.
