Abstract

PURPOSE: Heavy-metal chelators and inorganic nanoparticles (NPs) have been examined as potential radioenhancers to increase the efficacy of external beam radiation therapy for various cancers. Most of these agents have, unfortunately, displayed relatively poor pharmacokinetic properties, which limit the percentage of injected dose (%ID/g) that localizes to tumors and which shorten the window for effective radiation enhancement due to rapid tumor washout. METHODS AND MATERIALS: To address these challenges, we sought to conjugate gadolinium-based ultrasmall (<5 nm) NPs to an antibody directed against the oncogenic MUC1-C subunit that is overexpressed on the surface of many different human cancer types. The binding of the anti-MUC1-C antibody 3D1 to MUC1-C on the surface of a cancer cell is associated with its internalization and, thereby, to effective intracellular delivery of the antibody-associated payload, promoting its effective tumor retention. As such, we examined whether systemically administered anti-MUC1-C antibody-conjugated, gadolinium-based NPs (anti-MUC1-C/NPs) could accumulate within cell-line xenograft models of MUC1-C-expressing (H460) lung and (E0771) breast cancers to improve the efficacy of radiation therapy (XRT). RESULTS: The %ID/g of anti-MUC1-C/NPs that accumulated within tumors was found to be similar to that of their unconjugated counterparts (6.6 ± 1.4 vs 5.9 ± 1.7 %ID/g, respectively). Importantly, the anti-MUC1-C/NPs demonstrated prolonged retention in in vivo tumor microenvironments; as a result, the radiation boost was maintained during the course of fractionated therapy (3 × 5.2 Gy). We found that by administering anti-MUC1-C/NPs with XRT, it was possible to significantly augment tumor growth inhibition and to prolong the animals' overall survival (46.2 ± 3.1 days) compared with the administration of control NPs with XRT (31.1 ± 2.4 days) or with XRT alone (27.3 ± 1.6 days; P < .01, log-rank). CONCLUSIONS: These findings suggest that anti-MUC1-C/NPs could be used to enhance the effectiveness of radiation therapy and potentially to improve clinical outcomes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
