A Case Report on Longitudinal Collection of Tumour Biopsies for Gene Expression-Based Tumour Microenvironment Analysis from Pancreatic Cancer Patients Treated with Endoscopic Ultrasound Guided Radiofrequency Ablation.
(MDPI, 2022-09-21)
BACKGROUND: Most patients with pancreatic ductal adenocarcinoma (PDAC) are metastatic at presentation with dismal prognosis warranting improved systemic therapy options. Longitudinal sampling for the assessment of treatment ...
Tracking Cancer Evolution Reveals Constrained Routes to Metastases: TRACERx Renal.
(CELL PRESS, 2018-04-19)
Clear-cell renal cell carcinoma (ccRCC) exhibits a broad range of metastatic phenotypes that have not been systematically studied to date. Here, we analyzed 575 primary and 335 metastatic biopsies across 100 patients with ...
Biopsy variability of lymphocytic infiltration in breast cancer subtypes and the ImmunoSkew score.
(NATURE PORTFOLIO, 2016-11-04)
The number of tumour biopsies required for a good representation of tumours has been controversial. An important factor to consider is intra-tumour heterogeneity, which can vary among cancer types and subtypes. Immune cells ...
Impact of mutational profiles on response of primary oestrogen receptor-positive breast cancers to oestrogen deprivation.
(NATURE PORTFOLIO, 2016-11-09)
Pre-surgical studies allow study of the relationship between mutations and response of oestrogen receptor-positive (ER+) breast cancer to aromatase inhibitors (AIs) but have been limited to small biopsies. Here in phase I ...
Heterogeneity in global gene expression profiles between biopsy specimens taken peri-surgically from primary ER-positive breast carcinomas.
(BIOMED CENTRAL LTD, 2016-04-01)
BACKGROUND: Gene expression is widely used for the characterisation of breast cancers. Variability due to tissue heterogeneity or measurement error or systematic change due to peri-surgical procedures can affect measurements ...
