Robotic Surgery in Treatment for Prostate Cancer - Antioxidants May not Prevent Prostate Cancer

Robotic Surgery in Treatment for Prostate Cancer - Antioxidants May not Prevent Prostate Cancer

Robotic Experiments

More than 230,000 men are diagnosed with prostate cancer every year.  A new study found that intake of dietary or supplemental antioxidants were not associated with a decreased risk of prostate cancer among men in the Prostate, Lung, Colorectal, and Ovarian (PLCO). 

The researchers found that vitamin E and beta-carotene supplementation may be associated with reduced prostate cancer risk in certain population subgroups.  Beta-carotene is a precursor to vitamin A. 

Vitamin E, C and carotenoids may play a role in preventing cancer development because of their ability to combat free radicals.  Free radicals are compounds that can cause damage to cellular DNA, lipid membranes, and proteins. 


Previous studies have found that vitamin E has been associated with a reduced risk of prostate cancer, and beta-carotene has been associated with increased lung cancer risk, according to a Journal of the National Cancer Institute press release. 

This week ABC World News Tonight is running special series about prostate cancer.  Last night the evening news program talked about robotic controlled prostate surgery.  In the series “Second Opinion: Prostate Cancer”, Tim Johnson compared robotic prostate surgery with standard “large incision” surgery. 

According to the news program, robotic surgery entails four small incisions and a 3-D camera that gives a highly magnified view inside the patient.  The surgeon operates the robotic arms from a console nearby. A pressurized gas pumped into the abdomen to help prevent bleeding.  The lack of bleeding allows for a pristine view of the prostate permitting the surgeon to identify the structures he normally would have trouble seeing through traditional open surgery.

Not all doctors agree that robotic surgery is best.  Dr. Peter Albertsen, a professor of surgery at the University of Connecticut Health Center, said that the robot's advantages are insignificant when compared with traditional open surgery done by experienced doctors.

Prostate cancer is the second leading cause of cancer death in men in the US.  The major problem is that prostate cancer cells are barely responsive even to high concentrations of chemotherapeutic agents or radiotherapy.  A recent study found that the curry spice Turmeric, also known as curcumin, when combined with watercress, cabbage, winter cress, broccoli, Brussels sprouts, kale, cauliflower, kohlrabi and turnips, significantly retarded the growth of cancerous tumors in mice.  This research appeared in the January 15th issue of the journal Cancer Research.
