Study at University Medicine Halle points to success of immunotherapy in the treatment of advanced stomach cancer
A clinical trial conducted by researchers at University Medicine Halle has shown that the lives of patients with a certain form of stomach cancer can be significantly prolonged when the current standard of care, which uses a combination of antibody therapy and chemotherapy to inhibit cell growth through receptor blockades, is supplemented by immunotherapy with the drug nivolumab.
Adding an anti-inflammatory medication to immunotherapy and standard chemotherapy drugs may provide long-term suppression of aggressive bladder tumor growth, according to a proof-of-concept study.
The findings of a new study suggest that a ketogenic diet — which is low in carbohydrates and protein, but high in fat — helps to kill pancreatic cancer cells when combined with a triple-drug therapy. In laboratory experiments, the ketogenic diet decreased glucose (sugar) levels in the tumor, suggesting the diet helped starve the cancer. In addition, this diet elevated ketone bodies produced by the liver, which put additional stress on the cancer cells.
A new study suggests that the malaria drug hydroxychloroquine inhibits pathways that drive resistance to the chemotherapy agent cisplatin in head and neck cancers and restores tumor-killing effects of cisplatin in animal models.
New research has identified that the frequently used chemotherapy drug (5-FU or Fluorouracil) is 100 per cent more effective at targeting tumors (rather than surrounding tissues) when administered using an optimized liposomal formulation.
A researcher has made a discovery that alters our understanding of how the body’s DNA repair process works and may lead to new chemotherapy treatments for cancer and other disorders. Researchers discovered that base excision repair has a built-in mechanism to increase its effectiveness — it just needs to be captured at a very precise point in the cell life cycle.
A new study — in mice — suggests that blocking a major inflammatory pathway that is activated in pancreatic cancer makes the tumors sensitive to chemotherapy and a type of immunotherapy that prompts the immune system’s T cells to attack the cancer cells. The therapy more than doubled survival in a mouse model of pancreatic cancer.
Results from an international, randomized, double-blind, placebo-controlled, phase 3 clinical trial indicate that adding the androgen-receptor inhibitor darolutamide to androgen-deprivation therapy and chemotherapy prolongs the survival of men with metastatic, hormone-sensitive prostate cancer.
A study is validating the use of genomic sequencing to predict the likelihood that patients with gastric cancer will derive benefit from chemotherapy or from immunotherapy.
New research suggests that chemotherapy could better target brain tumors in mouse models when it was administered at night instead of during the day. That’s because the blood-brain barrier was more likely to allow the chemotherapy to pass through it at night. The findings highlight the importance of this area of research in humans, and one day, they could help to improve outcomes in patients with brain tumors.
A study has found that patients with cancer who receive chemotherapy — and some targeted therapies, such as CDK4/6 inhibitors and therapies targeted at B cells — may mount an inadequate immune response to COVID-19 vaccination.
Cancer patients undergoing chemotherapy can experience severe side effects that persist long after treatments end. A new study has found a novel pathway for understanding why these debilitating conditions happen — and why scientists should focus on ‚all of the possible neural processes that deliver sensory or motor problems to a patient’s brain‘ and not just those that occur away from the center of the body.
Standard chemotherapies may efficiently kill cancer cells, but they also pose significant risks to healthy cells, resulting in secondary illness and a diminished quality of life for patients. To prevent the previously unavoidable damage, researchers have developed a new class of nanomaterials engineered to capture chemotherapy drugs before they interact with healthy tissue.
Previous research has found that chemotherapy can trigger muscle loss in people living with cancer, but a new study out of found it may also affect the way the body builds new muscle — and at lower doses than previously known, having potential implications for treatments and rehab programs.
Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept study, researchers have made fish-shaped microrobots that are guided with magnets to cancer cells, where a pH change triggers them to open their mouths and release their chemotherapy cargo.
Using an experimental system involving new genetic technology, researchers analyzed the gene expression signatures of a representative sample of barcoded leukemia cells. After implanting some of the leukemia cells in mice, they discovered that distinct gene expression signatures correlated with the various organs where the cancer cells ended up. They were also able to identify previously unknown genes that are involved in disease progression and chemotherapy resistance, which may offer new targets for treatment.
Immunotherapy-chemotherapy treatment coupled with in-depth genomic analyses leads to improved survival for patients with mesothelioma
Combining the immunotherapy agent durvalumab with the chemotherapy agents pemetrexed and cisplatin or carboplatin may provide a new treatment option for patients who have inoperable pleural mesothelioma, a cancer of the tissues lining the lungs, according to a phase II clinical trial.
New evidence suggests that adding the targeted therapy ibrutinib (Imbruvica) to a standard chemotherapy regimen can improve how long some younger people with a specific form of diffuse large B-cell lymphoma (DLBCL) live.
A new study adds to the evidence that chemotherapy enhances cancer’s spread beyond the primary tumor, showing how one chemo drug allows breast cancer cells to squeeze through and attach to blood vessel linings in the lungs.
A drug commonly used to treat cancer can restore memory and cognitive function in mice that display symptoms of Alzheimer’s disease, new research has found. The drug, Axitinib, inhibits growth of new blood vessels in the brain — a feature shared by both cancer tumors and Alzheimer’s disease. This hallmark represents a new target for Alzheimer’s therapies. Mice that underwent the therapy not only exhibited a reduction in blood vessels and other Alzheimer’s markers in their brains, they also performed remarkably well in tests designed to measure learning and memory.
Cancer cells proliferate despite a myriad of stresses — from oxygen deprivation to chemotherapy — that would kill any ordinary cell. Now, researchers have gained insight into how they may be doing this through the downstream activity of a powerful estrogen receptor. The discovery offers clues to overcoming resistance to therapies like tamoxifen that are used in many types of breast cancer.
A chemotherapy drug known to cause hearing loss in children is more likely to do so the earlier in life children receive it, new UBC research has found. Cisplatin is a life-saving treatment for many children with cancer, but the study shows that the hearing of very young children is impacted early during treatment and is affected to a greater extent than that of older children.
Combining chemotherapy with a BRAF oncogene inhibitor proves effective at treating this disease in a mouse model. This alternative paves the way toward a new approach for patients affected by this type of tumor, which has no cure in the most advanced stages or cases of relapse.
Scientists reveal that during hematopoietic regeneration, RNA expressed from a part of the genome considered ‚junk DNA‘ is used by hematopoietic stem cells to get activated and proliferate. The study shows that these so-called transposable elements make RNA after chemotherapy and activate an immune receptor which induces inflammatory signals enhancing hematopoietic stem cell cycling and thus participating in the regeneration of the hematopoietic system.
