Tumor localization using radiolabeled monoclonal antibodies. An overview.

J R Zalcberg

    American Journal of Clinical Oncology
    |December 1, 1985
    PubMed
    Summary

    Radiolabeled monoclonal antibodies show promise for tumor localization, even without perfect specificity. Advances in antibody fragments, isotopes, and imaging techniques like single photon emission computerized tomography can enhance tumor detection and resolution.

    Main Results:

    • Specific tumor localization is achievable despite inherent limitations of monoclonal antibody specificity.
    • Antibody fragments and alternative radiolabels (e.g., non-iodine isotopes) can improve detection sensitivity.
    • Advanced imaging, such as single photon emission computerized tomography (SPECT), enhances resolution.

    Conclusions:

    • Radiolabeled monoclonal antibodies offer a viable strategy for tumor localization.
    • Overcoming challenges like tumor heterogeneity and circulating antigens is crucial for clinical success.
    • Accurate detection of lymph node metastases using this technology holds significant clinical potential.
