Spatial transcriptomics reveals discrete tumour microenvironments and autocrine loops within ovarian cancer subclones.

High-grade serous ovarian carcinoma (HGSOC) is genetically unstable and characterised by the presence of subclones with distinct genotypes. Intratumoural heterogeneity is linked to recurrence, chemotherapy resistance, and poor prognosis. Here, we use spatial transcriptomics to identify HGSOC subclones and study their association with infiltrating cell populations.

TRACEBACK: Testing of Historical Tubo-Ovarian Cancer Patients for Hereditary Risk Genes as a Cancer Prevention Strategy in Family Members.

Purpose: Tubo-ovarian cancer (TOC) is a sentinel cancer for and pathogenic variants (PVs). Identification of a PV in the first member of a family at increased genetic risk (the proband) provides opportunities for cancer prevention in other at-risk family members. Although Australian testing rates are now high, PVs in patients with TOC whose diagnosis predated revised testing guidelines might have been missed.

Advance care planning documentation strategies; goals-of-care as an alternative to not-for-resuscitation in medical and oncology patients. A pre-post controlled study on quantifiable outcomes.

Background: Health services in Tasmania, Victoria and now Western Australia are changing to goals-of-care (GOC) advance care planning (ACP) documentation strategies.

Aim: To compare the clinical impact of two different health department-sanctioned ACP documentation strategies.

Methods: A non-blinded, pre-post, controlled study over two corresponding 6-month periods in 2016 and 2017 comparing the current discretional not-for-resuscitation (NFR) with a new, inclusive GOC strategy in two medical/oncology wards at a large private hospital.
