SUMMARY

In order to advise the Federal Government on the reimbursement of molecular tests related to Personalised Medicine in Oncology, the Commission of Personalised Medicine (ComPerMed), represented by Belgian experts, has developed a methodology to classify molecular testing in oncology. The different molecular tests per cancer type are represented in algorithms and are annotated with a test level reflecting their relevance based on current guidelines, drug approvals and clinical data. The molecular tests are documented with recent literature, guidelines and a brief technical description. This methodology was applied on different solid tumours for which molecular testing is a clear clinical need.

Metastatic breast phyllodes tumour: is chemotherapy effective?

BJMO - volume 11, issue 1, february 2017

SUMMARY

Breast phyllodes tumours account for less than 0.5% of breast tumours, their diagnosis is therefore often made after pathological exam. They are fibroepithelial lesions of the breast, and are classified as benign, borderline or malignant. For malignant phyllodes tumours, aggressive behaviour with risk of local and distant recurrence may be seen. Therefore, at least one centimetre free-margins, or mastectomy, should be preferred for local malignant tumours. No prospective randomised data exist to elucidate the role of adjuvant chemotherapy, but radiotherapy should probably be offered after breast conservative surgery for borderline and malignant tumours. For metastatic disease, there is no standard chemotherapy regimen. Doxorubicin is the main recommended drug, based on scarce data. Palliative surgery or radiotherapy may also be offered. We present here a patient with lung metastatic disease who partially responded to a platin-etoposide regimen after doxorubicin failure, and make a short review of the literature.

Immunotherapy for genitourinary cancers: where are we?

BJMO - volume 11, issue 9, february 2017

E. Seront MD, PhD, J.P. Machiels MD, PhD

Immunotherapy harnesses the immune system to recognize and destroy cancer cells. This review focuses on the different agents that are currently approved in genitourinary cancers and highlights promising therapeutic strategies in this field. The clinical data generated in advanced urological cancer, advanced renal cell carcinoma (RCC) and metastatic prostate cancer will be discussed

Pan-HER inhibitors

BJMO - volume 9, issue 3, july 2015

S. Lejeune MD, J.P. Machiels MD, PhD

The human epidermal growth factor receptor family is composed of four tyrosine kinase receptors (HER-1 or EGFR, HER-2, HER-3 and HER-4). Human epidermal growth factor receptor pathways play a critical role in human cancer and are involved in tumour proliferation, apoptosis, angiogenesis, and cell migration/invasion. Pan-HER inhibitors such as afatinib, dacomitinib, and neratinib induce irreversible inhibition of all the dimers formed by the human epidermal growth factor receptor family. In clinical practice, only afatinib is approved by the Food and Drug Administration for the first-line treatment of patients with metastatic non-small cell lung cancer whose tumours have epidermal growth factor receptor exon 19 deletions or exon 21 (L858R) substitution mutations. Today, those molecules are still in development and their activity and safety investigated in clinical trials. The most common adverse effects of the pan-HER inhibitors are diarrhoea and skin toxicity.
