The recent approval of the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) harbouring pathogenic variants of BRCA2 or BRCA1 marks the start of molecularly guided precision medicine in prostate cancer. In parallel with this approval comes the need to embed molecular diagnostics in the clinical management of patients with mCRPC. To date, however, there are no established protocols in Belgium for the use of mutation testing in this setting. This article will therefore provide practical guidance for sample preparation and handling, pre-analytic processing, and pathogenic variant analysis in mCRPC. Across the different phases of this process, a multidisciplinary approach involving urologists, oncologists, radiologists, pathologists, molecular biologists, technicians, nurses, and geneticists will be key to safeguard adequate sample selection to perform molecular analyses at the time of metastatic disease. It will also facilitate high-quality molecular testing with a minimal failure rate. Only by optimising this process will physicians be able to adequately select mCRPC patients that are most likely to benefit from PARP inhibition, or other future targeted therapies, allowing to use these agents in the correct patient groups.

Stromal tumour of unknown malignant potential (STUMP) is a rare type of mesenchymal tumour of the prostate. These tumours often cause obstructive urinary symptoms, haematuria or haematospermia and can be misdiagnosed as benign prostatic hyperplasia (BPH). STUMP has a variable and unpredictable clinical course. Generally, these tumours have a good prognosis since they are mostly confined to the prostate. However, a minority recurs after surgery and uncommonly can adhere to adjacent organs or (even more rarely) metastasizes. Progression to prostatic stromal sarcoma has rarely been reported. The diagnosis is made on histological examination of prostate tissue (from biopsy or transurethral resection of the prostate (TURP)). The appropriate treatment approach is currently unknown. Treatment recommendations should be based on patient age, treatment preference, size or extent of the lesion. This case report describes a case of a 68-years old man who presented with a STUMP and provides an overview of the literature on this topic.

Succinate dehydrogenase deficient renal cell carcinoma (SDH-RCC) is a very rare but distinct renal neo-plasm, most often presenting at a young age and commonly associated with paragangliomas, pheochromocytomas and gastro-intestinal stromal tumours as a hereditary cancer syndrome. Although SDH-RCCs often have a relatively indolent disease course, higher nuclear grade, coagulative necrosis and sarcomatoid dedifferentiation may indicate aggressive disease. Radical surgery and (targeted) radiation therapy are valuable options in the treatment of these rare tumours. Genetic testing for germline SDH mutations is crucial. First-line relatives with germline SDH mutations should undergo periodical screening since early detection is paramount. The strong presence of the Warburg effect in SDH-related tumours make these the hallmark tumour for 18Fluorodeoxyglucose Positron Emission Tomography based screening and follow-up.

In order to advise the Federal Government on all matters related to personalised medicine in oncology, including the reimbursement of molecular tests, the Commission of Personalized Medicine (ComPerMed) has applied, for the breast tumours, the same methodology as previously applied for the digestive tumours. Meaning, the different molecular tests, represented in the shape of algorithms, are annotated with test levels — which aim to reflect their relevance based on current available data and to define the reimbursement — and are documented with recent literature, guidelines and a brief technical description.

The Belgian Working Group on Uropathology has agreed upon a dataset for prostate core needle biopsy reporting, based on existing international guidelines, recent scientific insights, national survey analysis and panel discussion, with the focus on a user- and receptor-friendly format. This dataset should encourage standardised structured reporting of prostate biopsies in the Belgian healthcare system, aiming to improve the quality of individual pathology reports and to provide real benefit for the clinical management of patients and secondary users. Therefore the Belgian Working Group on Uropathology recommends implementing this dataset in each Belgian pathology lab, in close consultation with the entire clinical team involved in the treatment of the prostate cancer patient.
