Multicenter Study
A first-in-human phase I study of SAR125844, a selective MET tyrosine kinase inhibitor, in patients with advanced solid tumours with MET amplification.
Dysregulated MET signalling is implicated in oncogenesis. The safety and preliminary efficacy of a highly selective MET kinase inhibitor (SAR125844) was investigated in patients with advanced solid tumours and MET dysregulation. ⋯ NCT01391533.

Comparative Study
The use of sentinel lymph node biopsy in the treatment of breast ductal carcinoma in situ: A Danish population-based study.
The risk of axillary metastases in breast cancer patients with only ductal carcinoma in situ (DCIS) is low. Thus, axillary staging with sentinel lymph node biopsy (SLNB) should only be used according to the current guidelines to avoid over-treatment and unnecessary morbidity. In the present study, the use of SLNB in patients with DCIS was evaluated nationally and compared across Danish departments. ⋯ The use of SLNB in patients with DCIS and adherence to the Danish national guidelines varies among Danish breast surgery departments. To optimise the axillary treatment of patients with DCIS, an improved compliance to the national DCIS guidelines is necessary.

At the moment of the diagnosis of hepatocellular carcinoma (HCC), 70% of patients have only access to palliative treatments, with very few therapeutic options. Liver immunology is very specific, and liver immunotolerance is particularly developed because of the constant and massive influx of antigens. Deregulation of hepatic immunotolerance is implicated in chronic liver diseases development and particularly in liver carcinogenesis. ⋯ Currently, only the final results of the tremelimumab phase II and the Nivolumab phase I/II study (CheckMate-040) are available. The latter is promising but need to be confirmed by the ongoing phase III studies to confirm the place of immunotherapy in the treatment of HCC. With many new molecular targets and therapeutic combination, immunotherapy represents a new hope in treating HCC patients although serious evaluation is still needed to confirm its interest.

The advent of anti-programmed death receptor-1/ligand-1 antibodies (anti-PD(L)1) is profoundly changing the therapeutic strategy of oncology. As anti-PD(L)1 modulate tumour microenvironment, it might impact sensitivity to conventional cancer therapy (CCT). Therefore, we explored whether sensitivity to CCT was different before and after anti-PD(L)1 therapy. ⋯ Patients who derive benefit from immune therapies tend to have better PFS on conventional therapies after having received the anti-PD(L)1 agent. Further studies on larger data sets are warranted to confirm these findings.

Patients treated with chemotherapy for microsatellite unstable (MSI) and/or mismatch repair deficient (dMMR) cancer metastatic colorectal cancer (mCRC) exhibit poor prognosis. We aimed to evaluate the relevance of distinguishing sporadic from Lynch syndrome (LS)-like mCRCs. ⋯ LS-like and sporadic MSI/dMMR mCRCs display distinct natural histories. MMR, BRAF mutation and MLH1 methylation testing should be mandatory to differentiate LS-like and sporadic MSI/dMMR mCRC, to determine in particular whether immune checkpoint inhibitors efficacy differs in these two populations.
