Blood test may help signal tumor's remission, return in throat cancer patients

...of a blood test that enables doctors to detect the recurrence of throat cancer early on, when there is still time to pursue a second line of treatment, such as surgery or drug therapy. “Cancers of the head and neck are insidious because surgical removal of the tumor can severely impair a person’s ability to ta...

Cancer stem cells similar to normal stem cells can thwart anti-cancer agents

...lls, which ultimately become the source of disease recurrence and eventual metastasis. Now, research by scientists at the University of Pittsburgh School of Medicine suggests that for chemotherapy to be truly effective in treating lung cancers, for example, it must be able to target a small subset of cancer ste...

How 'memory' T cells curb the spread of viruses throughout the body

...iruses, the body becomes “immune” (protected) from recurrence of the same disease. This is why before vaccines ... as “memory lymphocytes” and protect the body from recurrence of the disease. Similarly, vaccines induce the production of memory lymphocytes, but without causin...

Gene thought to assist chemo may help cancer thrive

...cer cells damaged by chemotherapy leading to tumor recurrence and explaining the higher mortality rate of patients whose tumors had a functioning p53. If we are correct, inhibiting p53 in tumors being treated with chemotherapy may substantially improve patients' long-term survival." McDonald and colleagues a...

Scientists identify pancreatic cancer stem cells

...er tumors shrink and may be responsible for cancer recurrence and metastasis. This study confirms at least one of those concepts, the researchers said. "Our study demonstrates that the very small subset of cells in a human pancreatic tumor that cause the cancer to grow and propagate have stem cell-like featu...

First-degree fetal heart block may be reversible

...ven with further intervention. "Given the high recurrence rate we confirmed in this study, close monitoring and the earliest possible marker is necessary," said Copel, who plans trials of other possible treatments. "Advanced block and permanent heart damage can occur within one week of a normal echocardiogr...

New cell type identified in cancer development

...ne the role of cancer stem cells in the growth and recurrence of the disease as well as offer new options for cancer prevention, detection and treatment. Current cancer stem cell theory holds that tumors are comprised of a variety of cell types. Among them is a small subset of rather primitive cells that, lik...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...ients. Four of the subjects have shown no signs of recurrence in the three years since the study began. "The trial was a look at the toxicity and feasibility of using a dendritic cell-based vaccine against pancreatic cancer," said Andrew Lepisto, Ph.D, post-doctoral researcher in the University of Pittsbu...

Tumor cells evade death through autophagy

This study has clinical implications as it indicates that adjunct treatment with inhibitors of autophagy might increase the efficacy of apoptosis-inducing chemotherapeutics in human patients with cancer. ...

Leukemic cells find safe haven in bone marrow

Previous research at St. Jude and elsewhere had shown that direct contact with bone marrow mesenchymal cells is essential for the long-term survival and multip...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

... 11 recovered. Of these, 88 percent were free from recurrence of heart disease five years later. Their quality of life was measured as being at nearly normal. Dr Emma Birks, from the Heart Science Centre at Imperial and the Royal Brompton and Harefield NHS Trust, and lead author of the study, said: "Donor he...

Cigarette smoking impedes tendon-to-bone healing

... studies have reported short- to intermediate-term recurrence rates from 30 percent to 90 percent, depending on the size of the tear, chronic nature of the injury and the age of the patient, among other factors. "Especially during the first six weeks after surgery, tissue may be vulnerable to re-injury," say...

Restoring tamoxifen sensitivity in resistant breast cancer cells

... tamoxifen treatment initially reduced the rate of recurrence by nearly 50 percent. Over time, however, patients develop resistance to the drug and tamoxifen loses its effectiveness as a cancer treatment. "Tamoxifen has been extremely important in the management of breast cancer," said NCI Director John E. Ni...

Recurrence of a flu pandemic similar to infamous 1918 flu could kill 62 million

Strangely, researchers still don't know exactly how many people died from this particular strain of the flu virus in that pandemic, and they know even less about how mortality rates varied in diffe...
