Journal ArticleDOI

Candidate biomarkers of PARP inhibitor sensitivity in ovarian cancer beyond the BRCA genes

TL;DR: Ovarian cancer patients with tumours harbouring loss-of-function mutations in HRR genes other than BRCA1/2 may constitute a small, molecularly identifiable and clinically relevant population who derive treatment benefit from olaparib similar to patients with BRCAm.
Journal ArticleDOI

A comparison of ARMS and DNA sequencing for mutation analysis in clinical biopsy samples

TL;DR: ARMS was more sensitive and robust at detecting defined somatic mutations than DNA sequencing on clinical samples where the predominant sample type was FF-PET, and improved both the sensitivity and speed of analysis compared with sequencing.
Journal ArticleDOI

Detection of BRAF mutations in the tumour and serum of patients enrolled in the AZD6244 (ARRY-142886) advanced melanoma phase II study.

TL;DR: Progression-free survival (PFS) of patients with BRAF+ tumour and cfDNA was not significantly different compared with tumour BRAF+, indicating that cfDNA BRAF detection is not associated with poorer prognosis on PFS in stage III/IV advanced melanoma.
