Abstract

Current methods to assess the drug response of individual human cancers are often inaccurate, costly, or slow. Functional approaches that rapidly and directly assess the response of patient cancer tissue to drugs or small molecules offer a promising way to improve drug testing, and have the potential to identify the best therapy for individual patients. We developed a digitally manufactured microfluidic platform for multiplexed drug testing of intact cancer slice cultures, and demonstrate the use of this platform to evaluate drug responses in slice cultures from human glioma xenografts and patient tumor biopsies. This approach retains much of the tissue microenvironment and can provide results rapidly enough, within days of surgery, to guide the choice of effective initial therapies. Our results establish a useful preclinical platform for cancer drug testing and development with the potential to improve cancer personalized medicine.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The presence of C2C12-secreted adenosine significantly decreased the extravasation of cancer cells within the bone microenvironment.

    “A deeper analysis revealed that the presence of C2C12‐secreted adenosine significantly decreased the extravasation of cancer cells within the bone microenvironment.”

    From 3D Biomimetic Models to Reconstitute Tumor Microenvironment In Vitro: Spheroids, Organoids, and Tumor‐on‐a‐Chip (2023) · cites this paper as [132]

    The Results sections on xenograft slice characterization and drug responses describe glioma tumor slices and drug testing, not cancer-cell extravasation in bone. Searches for C2C12, adenosine, and the claimed extravasation finding found no passage addressing it in our copy. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • In a microvascular network embedded in a bone-like or muscle-like microenvironment, the extravasation rate and vessel permeability were much higher in the bone-mimicking microenvironment than in the muscle-mimicking microenvironment.

    “It was found that the extravasation rate and vessel permeability were much higher in the bone‐mimicking microenvironment than in the muscle‐mimicking microenvironment.”

    From 3D Biomimetic Models to Reconstitute Tumor Microenvironment In Vitro: Spheroids, Organoids, and Tumor‐on‐a‐Chip (2023) · cites this paper as [132]

    The Results section on drug delivery describes diffusion into tumor slices, not extravasation from a microvascular network. The Discussion says the system does not reproduce in vivo delivery by capillaries. Searches for bone- and muscle-mimicking environments, extravasation, and vessel permeability found no comparison supporting the claim; page numbers were unavailable in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • Metastasis organ specificity and extravasation appear to be tightly coupled because specific chemo-attractant molecules are secreted by organ-specific stromal cells.

    “Metastasis organ specificity and extravasation appear to be tightly coupled because specific chemo‐attractant molecules are secreted by organ‐specific stromal cells.”

    From 3D Biomimetic Models to Reconstitute Tumor Microenvironment In Vitro: Spheroids, Organoids, and Tumor‐on‐a‐Chip (2023) · cites this paper as [132]

    The Results describe drug testing on a colorectal cancer liver metastasis and identify stromal cells in tumor slices, but do not discuss how metastases select organs or extravasate. Searches for chemo-attractants and organ-specific stromal secretion found no passage addressing the proposed mechanism. (LLM, conf=0.76)

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.
