Does cancer research focus on areas of importance to patients?

We performed a 4 week pilot patient survey at the Royal Marsden (a specialist cancer centre) to investigate patients' views on priorities for cancer research. A total of 780 patients completed the survey and the top research priorities were identified as: detection and prevention of cancer, scientific understanding, curative treatment and personalised treatment. The top research priorities were remarkably consistent across age, gender and a variety of tumour types. We believe that patients' views should be considered alongside those of clinicians and researchers when devising research proposals and strategies.Peer reviewedFinal Published versio

Case Report: Response to ipilimumab and nivolumab in a patient with adrenocortical carcinoma

Background: Adrenocortical carcinoma (ACC) is a rare malignancy with limited treatment options. The evidence for the use of immunotherapy in ACC has been conflicting, with overall response rates ranging from 6 – 33%. Case presentation: We describe the case of a 32 year old patient who was initially thought to have an inoperable clear cell renal cell carcinoma and was treated with immunotherapy with ipilimumab and nivolumab. The patient had an excellent partial response to treatment. Further work-up prior to consideration of surgery demonstrated that the tumour was an ACC, rather than a renal cancer. She had a right adrenalectomy and right hepatectomy, achieving an R0 resection and remains disease-free one year after surgery. Conclusion: This case illustrates the challenge of diagnosing ACC, and that doublet immunotherapy with ipilimumab and nivolumab can have significant clinical efficacy in ACC

Detecting and Tracking Circulating Tumour DNA Copy Number Profiles during First Line Chemotherapy in Oesophagogastric Adenocarcinoma

DNA somatic copy number aberrations (SCNAs) are key drivers in oesophagogastric adenocarcinoma (OGA). Whether minimally invasive SCNA analysis of circulating tumour (ct)DNA can predict treatment outcomes and reveal how SCNAs evolve during chemotherapy is unknown. We investigated this by low-coverage whole genome sequencing (lcWGS) of ctDNA from 30 patients with advanced OGA prior to first-line chemotherapy and on progression. SCNA profiles were detectable pretreatment in 23/30 (76.7%) patients. The presence of liver metastases, primary tumour in situ, or of oesophageal or junctional tumour location predicted for a high ctDNA fraction. A low ctDNA concentration associated with significantly longer overall survival. Neither chromosomal instability metrics nor ploidy correlated with chemotherapy outcome. Chromosome 2q and 8p gains before treatment were associated with chemotherapy responses. lcWGS identified all amplifications found by prior targeted tumour tissue sequencing in cases with detectable ctDNA as well as finding additional changes. SCNA profiles changed during chemotherapy, indicating that cancer cell populations evolved during treatment; however, no recurrent SCNA changes were acquired at progression. Tracking the evolution of OGA cancer cell populations in ctDNA is feasible during chemotherapy. The observation of genetic evolution warrants investigation in larger series and with higher resolution techniques to reveal potential genetic predictors of response and drivers of chemotherapy resistance. The presence of liver metastasis is a potential biomarker for the selection of patients with high ctDNA content for such studies
