Overview
Background
Peter Simpson is a recognised expert in the molecular and pathological characterisation of breast and lung cancers. His research is based at the UQ Centre for Clinical Research (UQCCR), where he is the Head of the Cancer Theme and is a Research Group Leader in Cancer Genomics. He has published >150 articles (>12,000 citations, H-index 52; Scopus, May2025) including in Nature, Nature Medicine, Annals of Oncology and the American Journal of Respiratory and Critical Care Medicine. He co-manages the Brisbane Breast Bank (BBB), a tissue bank created to facilitate clinical breast cancer research, and the Debutant lung cancer Program.
Pete also holds a teaching appointment in UQ, where he is passionate about the science and clinical applications of Pathology. He teaches into the UQ Medical Program (Year 1 and 2), as well as to undergraduates. He has co-authored a chapter ‘Breast Diseases’ in the latest edition (11th) of the internationally acclaimed Medical text book Robbins and Cotran Pathologic Basis of Disease.
Outside UQ, Pete is a Fellow of the Faculty of Science in the Royal College of Pathologists of Australasia (FFSc RCPA), a member of the kConFab Executive (https://www.kconfab.org/), a member of the Lobular Breast Cancer Alliance Scientific Advisory Board (https://lobularbreastcancer.org/), and a member of the International Cancer Genome Consortium (Breast Cancer group).
Pete enjoys supervising students at all levels in their careers and collaborating within multidisciplinary teams spanning clinical (e.g. pathology, oncology) and science teams (e.g. in ‘omics, bioinformatics and machine learning).

Broad Research Program
Cancer is a very heterogeneous disease, making morphological classification and management of patients a significant challenge. Despite great advances it remains difficult to predict which patients are at risk of their disease returning (recurrence), spreading (metastasis) or which patients will gain most benefit to specific therapies. There has therefore been a concerted effort to supplement the morphological classification of disease with molecular data that can provide a clearer appreciation for this complexity and better predict tumour behaviour. This ideology has driven significant advancements in the field of molecular pathology research. My research program embraces these advances in technology to help better understand mechanisms of disease development and progression and help improve the molecular aspects of diagnosis and patient management. Themes of research involve 1) invasive lobular carcinoma of the breast, 2) breast cancer diagnosed in young individuals, and 3) lung cancer.

Invasive Lobular Carcinoma
Invasive Lobular Carcinoma (ILC) is the most commonly diagnosed ‘special’ morphological type of breast cancer, comprising up to 15% of all cases. The most important biological feature of lobular breast cancer is the functional loss of cell adhesion molecule E-cadherin. This is the glue that holds epithelial cells together. Loss of E-cadherin leads to a growth pattern that can be diffuse and highly invasive through the breast tissue. This leads to a number of important clinical challenges with diagnosing and managing this cancer: the cancer can be hard to palpate or detect by mammographic screening and hard to fully excise during surgery; if the cancer spreads it can again be hard to detect. A large component of Peter's research focuses on aspects of this specific cancer subtype, including understanding molecular determinants that predict tumour behaviour and prognosis, and mechanisms of invasion and metastasis.
-
Familial Breast Cancer
Family history is a significant risk factor for the development of breast cancer, often leading to early diagnosis of disease. For some families, the genetic component of this risk is well understood and attributed to pathogenic germline variants in moderate-high risk genes (e.g. BRCA1, BRCA2, PALB2, TP53, ATM, CHEK2). For many families the underlying genetic risk is unknown. Further, some individuals develop breast cancer at a young age when they have no family history. We study clinical samples using a variety of molecular profiling techniques, including whole genome sequencing and digital spatial transcriptomics, and we are interested in understanding the germline and somatic molecular mechanism that contribute to the development of disease. This work is a collaboration with several tissue banks: kConFab, the BBB and the Australian Breast Cancer Tissue Bank.

Lung Cancer Diagnostics
Lung Cancer has the highest mortality of all cancers. Most cases are diagnosed at an advance, inoperable stage and so are associated with a poor prognosis. Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) sampling is an important procedure to make a tissue diagnosis of disease and to provide specimens for molecular testing. Next generation sequencing is an important component of diagnostic practice and therapeutic decision making for lung cancer patients. Our program of work is focused on optimising molecular testing strategies from different types of cancer samples (tissue, supernatant, cfDNA) to improve the success of testing for patients. This is a collaboration with A/Prof David Fielding (https://about.uq.edu.au/experts/9060) from the Department of Thoracic Medicine (RBWH), plus colleagues from Pathology Queensland, QIMR Berghofer and a network of hospitals around Australia.
Research impacts
Breast cancer is the most diagnosed cancer in women worldwide and consequently is the biggest contributor to morbidity and mortality from cancer.
My work in the field of breast cancer genomics has sought to unravel molecular mechanisms driving the evolution of disease, from early lesions through to treatment resistance and metastatic progression. Our work uses various types of ‘omics applications, including whole genome sequencing and spatial transcriptomics, married with detailed cancer morphology assessment. Gene mutations and mutational signature analysis in the context of sporadic and familial breast cancer has revealed pathogenic germline mutations, different mechanisms of genomic evolution and clonal heterogeneity. The work through the International Cancer Genome Consortium contributed to the development of HRDetect (Nature Medicine) for therapeutic decision making.
My work in lobular breast cancer has an international standing. As a research community, we aim to raise the profile of lobular breast cancer as an important, common and yet understudied type of breast cancer. We have demonstrated this disease is in fact a heterogenous subtype, exhibiting morphological variants and diverse genomic features. We developed LobSig as a potential prognostic tool for lobular breast cancer, which is undergoing further validation. We have a program of work to better understand the biology of disease and identify tissue- and blood-based biomarkers of disease progression.
Lung cancer is the highest mortality rate of all cancers worldwide. The Debutant lung cancer clinical research program was established in 2018 and has sought to optimise and expand lung cancer molecular testing applications. The work has been funded by various sources, including Pathology Queensland, Royal Brisbane & Women’s Hospital Foundation, Cancer Council Qld, Cancer Australia, Australian Genomics and the Medical Research Future Fund (MRFF). The work has demonstrated the clinical utility of very small cytology samples and blood (cfDNA) samples using comprehensive genomic assays. The translation of results from this Program could significantly enhance the number of patients eligible for targeted therapies.
