Prostate cancer treatment may encourage spread of cancer cells

According to a new study by researchers in the U.S. the popular prostate cancer treatment, androgen deprivation therapy, may in fact encourage the spread of cancer cells throughout the body.

Additional biopsy-scoring data may help determine prostate cancer prognosis

Men with certain scores and patterns based on prostate cancer biopsy were found to be at higher risk of PSA-failure, suggesting that this measurement could help predict the risk of prostate cancer recurrence, according to preliminary research published in the October 3 issue of JAMA.

Missouri-Columbia researchers look at mechanisms of cisplatin drug sensitivity

Resistance to chemotherapy treatments can be the worst news a cancer patient ever receives. A pair of researchers at the University of Missouri-Columbia is working steadfastly to learn why some tumors eventually build a tolerance to the common chemotherapy drug cisplatin, in hopes of identifying the particular genes that can be manipulated to make treatment as effective as possible.

Androgen deprivation therapy for prostate cancer may encourage spread of disease

A popular prostate cancer treatment called androgen deprivation therapy may encourage prostate cancer cells to produce a protein that makes them more likely to spread throughout the body, a new study by Johns Hopkins researchers suggests.

New molecular evidence of the role of the hormone prolactin in breast cancer

They have found that prolactin, a pituitary hormone that normally stimulates breast development and milk production, initiates a new “signaling pathway” that may regulate the growth and survival of breast cancer cells.

The jury is in: microRNAs can cause tumors to metastasize

These tiny molecules fine-tune protein production and play a powerful role in biological processes ranging from development to aging. Now scientists have proved that they can prompt otherwise sedentary cancer cells to move and invade other tissues.
