Abstract

The use of nanomedicine for antitumor therapy has been extensively investigated for a long time. Enhanced permeability and retention (EPR) effect-mediated drug delivery is currently regarded as an effective way to bring drugs to tumors, especially macromolecular drugs and drug-loaded pharmaceutical nanocarriers. However, a disordered vessel network, and occluded or embolized tumor blood vessels seriously limit the EPR effect. To augment the EPR effect and improve curative effects, in this review, we focused on the perspective of tumor blood vessels, and analyzed the relationship among abnormal angiogenesis, abnormal vascular structure, irregular blood flow, extensive permeability of tumor vessels, and the EPR effect. In this commentary, nanoparticles including liposomes, micelles, and polymers extravasate through the tumor vasculature, which are based on modulating tumor vessels, to increase the EPR effect, thereby increasing their therapeutic effect.

  • Many clinical cancers such as late-stage and refractory tumors are associated with poor blood flow due to coagulation and thrombi formation, exhibiting poor EPR effect.

    “However, many clinical cancers such as late-stage tumors and refractory tumors are associated with poor blood flow due to the coagulation and thrombi formation exhibiting poor EPR effect [7,8,9,10,11,12].”

    From Approaches to Improve EPR-Based Drug Delivery for Cancer Therapy and Diagnosis (2023) · cites this paper as [11]

    Sections 2.1 and 2.2 (pages not provided) explain that abnormal tumor vessels can impair blood flow and interfere with the EPR effect. They attribute poor perfusion to vascular abnormalities and solid stress, not to coagulation or thrombi formation, and do not establish the claim specifically for late-stage or refractory tumors.

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.
