On October 3, Armstrong had an orchiectomy to remove the diseased testicle. When Reeves was asked in a later interview what he thought Armstrong's chances of survival were, he said, "Almost none. We told Lance initially 20 to 50% chance, mainly to give him hope. But with the kind of cancer he had, with the x-rays, the blood tests, almost no hope." After receiving a letter from Steven Wolff, an oncologist at Vanderbilt University, Armstrong went to the Indiana University medical center in Indianapolis and decided to receive the rest of his treatment there. The standard treatment for Armstrong's cancer was a "cocktail" of the drugs bleomycin, etoposide, and cisplatin (or Platinol) (BEP). The first chemotherapy cycle that Armstrong underwent included BEP, but for the three remaining cycles, he was given an alternative, vinblastine etoposide, ifosfamide, and cisplatin (VIP), to avoid lung toxicity associated with bleomycin. Armstrong credited this with saving his cycling career. At Indiana University, Lawrence Einhorn had pioneered the use of cisplatin to treat testicular cancer. Armstrong's primary oncologist there was Craig Nichols. On October 25, his brain lesions which were found to contain extensive necrosis, were surgically removed by Scott A. Shapiro, a professor of neurosurgery at Indiana University. Armstrong's final chemotherapy treatment took place on December 13, 1996. In January 1997, Armstrong unexpectedly appeared at the first training camp of the Cofidis team at Lille, riding with his new teammates before returning to the United States. In February 1997, he was declared cancer-free. In October, Cofidis announced that his contract would not be extended, after negotiations broke down over a new deal. A former boss at Subaru Montgomery offered him a contract with the US Postal team at a salary of $200,000 a year. By January 1998, Armstrong was engaged in serious training for racing, moving to Europe with the team. Before his cancer treatment, Armstrong had participated in four Tour de France races, winning two stages. In 1993, he won the eighth stage and in 1995; he took stage 18 which he dedicated to teammate Fabio Casartelli who had crashed and died on stage 15. Armstrong dropped out of the 1996 Tour after the fifth stage after becoming ill, a few months before his diagnosis. Armstrong's cycling comeback began in 1998 when he finished fourth in the Vuelta a España.
