Will finding the optimal dosing regimen be the key to unlocking the potential of ATR inhibitors?
Novel scheduling of RP-3500 mitigates haematological toxicity and may facilitate combination therapy but tumour types most likely to respond remain to be defined

The genomic, immunological and clinical characterisation of breast cancer – a work in progress
A greater understanding of the complexity of breast cancer, in all its forms, is key to better patient selection, new target development and improved outcomes, says Prof. Fabrice André

Sitravatinib shows signals of enhancing checkpoint inhibitor efficacy in NSCLC progressing on immunotherapy
Early-phase trials suggest that sitravatinib may reboot the tumour response to PD-1 inhibitors, but confirmation of efficacy is required and strategies are needed to adjust tolerability

Exploring targeted degradation of KRAS G12C with PROTACs
Developing therapies for cancers harbouring KRAS mutations has proven difficult but PROTACs, acting via targeted protein degradation, may help combat previously undruggable proteins

Incorporating proteomics into sarcoma research: where do we stand?
Proteomic research on sarcomas is only in its infancy, but it offers potential in terms of improved biological understanding, identification of new treatment targets and generating biomarkers for patient selection and prognosis prediction

What level of evidence do we need for drug approval in rare cancers?
Achieving clarity in levels of clinical evidence required by regulatory bodies is still a major obstacle to expediting research in the field, says Prof. Paolo G. Casali from the Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, and the University of Milan, Italy

Molecular management of metastatic GIST – challenges and opportunities
Thanks to remarkable advances, molecular analysis has taken central stage in the management of GIST, but there is still a need for less costly testing and further development of mitigation strategies to overcome resistance

What is on the horizon for the management of osteosarcoma?
2021 ESMO–EURACAN–GENTURIS–ERN PaedCan Clinical Practice Guidelines open the door to genetic testing but the search for new treatments continues

Is there a future for immunotherapy in sarcoma?
Continued efforts in patient selection, combination strategies and novel approaches may help to turn the tide for immunotherapeutics in sarcoma, according to Prof. Jean-Yves Blay

Single-agent doxorubicin – is it still the standard first-line therapy for all soft tissue sarcoma subtypes?
In practice, doxorubicin alone is often not used as the first-line standard of care for soft tissue sarcomas; however, a lack of high-quality survival data precludes other regimens becoming the gold standard
