The world's first drugs designed to stop cancer cells becoming resistant to treatment could be available within the next decade, scientists have said.
A £75m investment to develop the drugs has been announced by the Institute for Cancer Research (ICR).
Chief executive Prof Paul Workman said cancer's ability to adapt to drugs is the biggest challenge in treatment.
The new drugs could make cancer a "manageable" disease in the long term and "more often curable", he said.
Researchers say existing treatments such as chemotherapy sometimes fail because the deadliest cancer cells adapt and survive, causing the patient to relapse.
Prof Workman said: "Cancer's ability to adapt, evolve and become drug resistant was the cause of the vast majority of deaths from the disease and the biggest challenge we face in overcoming it."
He said the institute was "changing the entire way we think about cancer" to focus on anticipating the way cancer cells will evolve to prevent them from becoming resistant to drugs.
The ICR aims to attract a further £15m of funding for its new Centre for Drug Discovery at its campus in Sutton, south London, which is intended to bring together almost 300 scientists from different fields.
Scientists aim to use new approaches including multidrug combination treatments and artificial intelligence to predict and influence the evolution of cancer cells, creating weaknesses that treatments can exploit.
Dr Andrea Sottoriva, deputy director of cancer evolution in the new centre, said: "Artificial intelligence and mathematical predictive methods have huge potential to get inside cancer's head and predict what it is going to do next and how it will respond to new treatments."
Researchers are already working on new drugs designed to stop a type of protein molecule called Apobec, which is part of the immune system hijacked by more than half of cancer types to speed up the evolution of drug resistance.
Prof Workman said laboratory testing and clinical trials for the new drugs would take around 10 years before they could potentially become available for patients.
He added: "We firmly believe that, with further research, we can find ways to make cancer a manageable disease in the long term and one that is more often curable, so patients can live longer and with a better quality of life."

Moreover, TAM also directly induces CSC properties of pancreatic tumor cells by activating signal transducer and activator of transcription 3 (stat3) and thus inhibits the antitumor CD8 T lymphocyte responses in the chemotherapeutic response 131. Because of the plasticity of CSCs, it has been suggested that what is cialis good for new the combinational therapy of targeting CSC pathways and conventional chemotherapeutics might have better therapeutic effect, which will be explained later in detail (Figure 1 ). In parallel, compared with epithelial cell lines, the mesenchymal cells have increased expression of genes involved in metastasis and invasion and are significantly less susceptible to egfr inhibition, including erlotinib, gefitinib, and cetuximab; at least partly via integrin-linked kinase (ILK) overexpression in mesenchymal cells. Moreover, the CSCs from the chemoresistant tumors have the unique ability to produce a variety of proinflammatory signals, such as IFN regulatory factor-5 (IRF5 which acts as a transcription factor specific for chemoresistant tumors to induce the M-CSF production, to consequently. To overcome tumour drug resistance, Professor McVie explained that we need to look at every component of a signalling pathway, not just individual genes. Treatment for...tadalafil 20 125
Similarly, pretreatment with hdac inhibitors may sensitize the prostate cialis news 5 chicago stem-like cells to radiation treatment through increased DNA damage and reduced clonogenic survival 146. Thus, because of the plasticity of CSCs, it is suggested that combinational therapy of CSC targeting and bulk tumor ablation may have better therapeutic effects to improve the clinical outcomes of cancer patients. Introduction, cancer is one of the leading causes of morbidity and mortality worldwide with about 20 of all deaths in developed countries. Thus, it is important to understand the characteristics and mechanisms by which CSCs display resistance to therapeutic agents. First, it has been indicated that activation of Wnt/ -catenin signaling enhances the chemoresistance to IFN- /5-FU combination therapy 161.
