The cancer angiogenesis co-culture assay: In vitro quantification of the angiogenic potential of tumoroids.

The treatment response to anti-angiogenic agents varies among cancer patients and predictive biomarkers are needed to identify patients with resistant cancer or guide the choice of anti-angiogenic treatment. We present "the Cancer Angiogenesis Co-Culture (CACC) assay", an in vitro Functional Precision Medicine assay which enables the study of tumouroid induced angiogenesis. This assay can quantify the ability of a patient-derived tumouroid to induce vascularization by measuring the induction of tube formation in a co-culture of vascular cells and tumoroids established from the primary colorectal tumour or a metastasis.

KRAS mutations in the parental tumour accelerate in vitro growth of tumoroids established from colorectal adenocarcinoma.

The aim of the present study was to characterize a patient-derived in vitro 3D model (ie tumoroid) established from colorectal adenocarcinoma. This study investigated the growth rate of tumoroids and whether the Kirsten rat sarcoma (KRAS) mutations in the parental tumour accelerate this rate. The tumoroids were established from surgical resections of primary and metastatic colorectal adenocarcinoma from 26 patients.

Efficacy and tolerability of BP-C1 in metastatic breast cancer: a Phase II, randomized, double-blind, and placebo-controlled Thai multi-center study.

Aims: The aim of this study was to compare the efficacy and tolerability of BP-C1 vs equal-looking placebo in metastatic breast cancer.

Materials And Methods: A randomized, double-blind, placebo-controlled multi-center study with a semicross-over design was performed. Sixteen patients received daily intramuscular injection of 0.

Serum type XVI collagen is associated with colorectal cancer and ulcerative colitis indicating a pathological role in gastrointestinal disorders.

Altered extracellular matrix (ECM) remodeling is an important part of the pathology of gastrointestinal (GI) disorders. In the intestine, type XVI collagen (col-16) plays a role in pathogenesis by affecting ECM architecture and induce cell invasion. Measuring col-16 in serum may therefore have biomarker potential in GI disorders such as colorectal cancer (CRC) and ulcerative colitis (UC).

Short-term spheroid culture of primary colorectal cancer cells as an in vitro model for personalizing cancer medicine.

Chemotherapy treatment of cancer remains a challenge due to the molecular and functional heterogeneity displayed by tumours originating from the same cell type. The pronounced heterogeneity makes it difficult for oncologists to devise an effective therapeutic strategy for the patient. One approach for increasing treatment efficacy is to test the chemosensitivity of cancer cells obtained from the patient's tumour.
