Here are some quotes from the link -

""Most cancer patients in this country die of chemotherapy."
-Dr. Alan Levin

A six- or twelve-month course of chemotherapy not only is a very unpleasant experience but also has its own intrinsic mortality...treatments now avert...perhaps 2 or 3 percent...of the 400,000 deaths from cancer that occur each year in the U.S."
- Prof John Cairns
Scientific American, 1985"

"In an article entitled "Chemotherapy: Snake-Oil Remedy?" that appeared in The Los Angeles Times of January 9, 1987, Dr. Martin F. Shapiro explained that while "some oncologists inform their patients of the lack of evidence that treatments work...others may well be misled by scientific papers that express unwarranted optimism about chemotherapy. Still others respond to an economic incentive. Physicians can earn much more money running active chemotherapy practices than they can providing solace and relief...to dying patients and their families." 

Dr. Shapiro is hardly alone. Alan C. Nixon, PhD, Past President of the American Chemical Society wrote that "As a chemist trained to interpret data, it is incomprehensible to me that physicians can ignore the clear evidence that chemotherapy does much, much more harm than good."  (Emphasis Added)
