Drug resistance has been a recognized problem in cancer treatment for decades. Recent progress in biomedical research has enhanced our understanding of the pathways and mechanisms that confer resistance to anticancer drugs.
Cancer drug resistance continues to be a major impediment in medical oncology. Clinically, resistance can arise prior to or as a result of cancer therapy.
Translational Relevance. In clinical trials, FGFR1-amplified lung cancer patients experienced limited benefit from FGFR inhibition. Here, we show two different mechanisms that cause subclonal emergence of resistance, thus providing a rationale for combination drug treatment.
Identifying mechanisms of immunotherapy resistance will not only help avoid such cases where patients stop responding to treatment, but will likely also shed light on so-called primary resistance, when a cancer never responds in the first place, says David Kaufman, the executive director of New Jersey–based Merck’s oncology translational research division.

The development of drug-resistant cancers is considered to be the most significant obstacle to the cure of cancer today. Nearly half of all patients with cancer suffer from tumours that are intrinsically resistant to chemotherapy, and most of the remaining half develop drug resistance during the course of their treatment. This book reviews the mechanisms and clinical implications of drug
We provide evidence for the existence of diverse mechanisms of primary drug resistance in -amplified lung cancer and provide a rational strategy to improve FGFR inhibitor therapies by …
Multidrug resistance of cancer cells is a major cause for the failure of anti-cancer chemotherapy in the treatment of cancer patients; indeed, multidrug resistance usually increases during chemotherapy. It has been recognized that multidrug resistance is multifactorial and that various cellular pathways are simultaneously involved in the clinical drug resistance of cancer patients. In this
Although transporters of MDR are responsible for the tumor resistance to many chemotherapeutic drugs currently used in cancer therapy, the mechanisms of resistance to platinum-based anti- tumor agents are through different pathways. In this article, the mechanisms of MDR transporters mediating resistance to the commonly used chemotherapeutic drugs and to platinum-based agents are …
31/01/2018 · A recent study revealed a novel drug resistance mechanism in which drug-sensitive cancer cells secrete various soluble factors (e.g., IGF and HGF) into the tumor microenvironment in response to targeted therapy. These secreted factors can promote the growth, dissemination and metastasis of drug-resistant cancer cells and support the survival of drug-sensitive cells. Therefore, …
biochemical mechanisms of drug resistance, the types of mutations in tumor cells that can alter drug handling are discussed. Three examples of resistance are analysed in more detail: resistance to the folate analogue methotrexate; the multidrug resistance caused by increased levels of P-glycoprotein, which extrudes drugs from the cell; and resistance to alkylating agents.

Cancer Drug Resistance One of the main causes of failure in the treatment of cancer is the development of drug resistance by the cancer cells. This is a very serious problem that may lead to recurrence of disease or even death.
Cancer remains one of the major leading causes of death worldwide. Acquisition of multidrug resistance (MDR) remains a major impediment to successful chemotherapy. As the name implies, MDR is not limited only to one drug but often associated to structurally and functionally unrelated chemotherapeutics.

Cancer is one of the leading causes of death. Despite the huge progress in the field of cancer drugs and therapies, the treatment outcome is still bleak for most cancer patients.
Studies on mechanisms of cancer drug resistance have yielded important information about how to circumvent this resistance to improve cancer chemotherapy and have implications for pharmacokinetics of many commonly used drugs.
Development of Drug-Resistance in Response to Different Drug Treatment Methods Currently, there are a wide variety of methods used by researchers to induce drug resistance in pancreatic cancer cells but a variation of the incremental method described by Shah [18] [20] is the most frequently used.
Advances in understanding the molecular mechanism that regulates the DNA damage-signaling pathway makes it possi ble to better define the key re gulatory targets involving the development of tumor resistance. In this brief report, we summarize the recent advances in DNA damage signaling, and discuss the potential targets for drug development and better design of clinical trials for cancer

The basis for drug resistance in melanoma is most likely dysregulation of apoptosis, although other mechanisms including drug transport, detox- ification, and enhanced DNA repair may also play a role.
Clinical trials have been initiated with agents that may inhibit the biochemical mechanisms of acquired drug resistance. Clinical trials are already in progress with alkylating agents combined with inhibition of GSH biosynthesis (i.e., buthionine sulfoximine) or enzymatic inhibitors of glutathione S‐transferase activity (i.e., ethacrynic acid). Furthermore, the combination of aphidicolin, an

However, cancer cells can become multidrug resistant, a phenomenon due to cells expressing mechanisms that cause simultaneous resistance to many different, structurally and functionally, unrelated drugs [6].
Antineoplastic resistance, often used interchangeably with chemotherapy resistance, is the multiple drug resistance of neoplastic (cancerous) cells, or the ability of cancer cells to survive and grow despite anti-cancer therapies.
Multiple drug resistance (MDR) describes a phenomenon whereby resistance to one drug is accompanied by resistance to drugs whose structures and mechanisms of action may be completely different. The term was first applied to the area of antibiotic-resistant infection [ 1 ] but was soon applied to cancer chemotherapy.
