Bartolo Colon back in action - 2011

2011 - Bartolo Colon back in action

Yankee pitcher Bartolo Colon was no longer pitching for a major league team. Closing in on 40 and plagued with injuries, it seems like the former Cy Young winner’s career was just about over.

But after signing with the Yankees this year, Colon’s career seems to be in full swing again. He’s won five games. He has an ERA, an earned run average of 3.1, and although he’s currently sidelined by an injured hamstring, he’s on pace for a better season than he’s had in years.

What happened?

His amazing comeback is being attributed, at least in part, to a medical treatment involving injecting cells taken from his own body back into spots where he has injuries. The cells then repair the damage. They were his own adult derived stem cells.

Colon reportedly had the procedure in April of last year in the Dominican Republic, and while the procedure is not itself illegal, Major League Baseball is looking into it to make sure no banned substances like human growth hormone were used.

Treating Advanced Breast Cancer with Adult Stem Cells

Thursday, August 4th, 2011

Reported by David Prentice, The Family Research Council

Stanford doctors have shown that women with advanced breast cancer show greater survival when treated with aggressive chemotherapy and their own adult stem cells.  Their study looked at long-term results for women with advanced, stage-4 breast cancer, who were treated 12-14 years ago with high-dose chemotherapy and their own, purified adult stem cells, compared to women who received chemotherapy and unpurified blood stem cells.

While the numbers of patients in this long-term study are small, the results are striking.  Five of the 22 women (23 percent) who received their purified adult stem cells are still alive, four of whom have no sign of disease.  Only seven of the 74 women (9 percent) who received the untreated cells are still alive, with five of those seven having no sign of disease.  Women who received their own purified adult stem cells had a median survival of 60 months, whereas those receiving unpurified stem cells had a median overall survival of 28 months.

Senior author Dr. Judith Shizuru said:

“Our study suggests that the high-dose therapy strategy can be modified to include the use of cancer-free purified blood stem cells to yield better overall outcomes in women with advanced breast cancer.”

The results were published online in the journal Biology of Blood and Marrow Transplantation.
