    The prognosmation of advanced pancreatic catheterization adenocarcinoma (PDAC) is poor, and the existing treatment options are not effective.
    and low vascular progenitics of connective wovens are significant features of PDAC, hindering the successful delivery of chemotherapy drugs.
    pancreatic assassine cells (PSCs), connective tissue produces key components and induces that mediate the pro-survival and pro-invasion capabilities of cancer cells through multiple signal cascades.
    the tumor-substation cross-dialogue is unlikely to be effectively blocked simply through treatments that target a single pathway.
    and the interaction of tumor-substring cells from multiple angles, such as the normalization of the substation that promotes connective tissue growth, may enhance the effectiveness of conventional chemotherapy.
    patients with PDAC showed a deficiency of fat-soluble vitamins due to impaired bile and pancreatic secretion.
    although vitamin K deficiency is clinically manifested and treated, vitamin A deficiency may make PSC active for a long time, which is not clinically recognized.
    in a healthy pancreas, PSC stores the metabolites of vitamin A (retinol) (RA).
    when activated in cancer or inflammation, PSC loses rabies storage and exhibits an active myoblast esogen.
    addition, RA is an important molecule that regulates key signaling path pathlines, mediated by embryonic pancreatic development, signal cascading, and hijacking during the on-occurrence of pancreatic cancer.
    based on these observations, researchers have shown that in various PDAC experimental models, the use of all-trans-responsicric acid (ATRA) can restore the RA library in the PSC, limiting connective tissue growth, and inhibiting tumor growth.
    addition, the researchers found that activated PSCs prevented immune cells from migrating into direct PDAC micro-environments, such as CD8 plus T cells, natural killers and B cells, a process that can be reversed by ATRA5.
    , ATRA is the ideal drug for suppressing a variety of amplified, embryonic, environment-specific signal cascades activated in PDAC.
    , researchers recently published a paper in the journal Nature Communications, using a two-step adaptive continuous reassessment trial design for a phase IB, dose upgrade, and expansion trial for patients with late-stage non-excision of PDAC (n-27), which ATRA uses as a substitit target drug in combination with gemcitabine-nab-yew alcohol chemotherapy.
    maximum to-dosage (MTD) and phase 2 recommended doses (RP2D, main results) are FDA/EMEA-approved gemcitabine-nab-yew alcohol doses used with ATRA (45 mg/m2 oral, 1-15 days/cycle).
    dose-limiting toxicity (DLT) was level 4 plate plate plate reduction (n s 2).
    results showed no damage to ATRA pharmacodynamics.
    total survival of the RP2D therapeuticly evaluated population was 11.7 months (95% CI 8.6-15.7 months, n s 15, local late stage and metastasis).
    exploratory pharmacoephic studies include changes in the oscic diffusion coefficient measured by diffusion weighting (DW)-MRI after a cycle, as well as the regulation of periodic-specific serotonin 3 levels of indicative substation regulation over different cycles.
    the expression of baseline-specific retin transport proteins (FABP5, CRABP2) may be a sign of reaction.
    in short, the use of gemcitabine-nab-yew alcohol and ATRA as substitin-targeted drugs is safe and toned.
    the combination will evaluate local late PDAC in a Phase II randomized controlled trial.
    clinical trial number EudraCT: 2015-002662-23; NCT03307148.
    test for short: STARPAC.
