While the null hypothesis was proven to be correct, the primary endpoint of presenting this research was to engage oncologists in being more attentive to correctly diagnosing and prescribing treatment for those patients who have recurring carcinoid tumors. As such, oncologists determined that the best treatments to be used are streptozotocin, 5-fluorouracil (5-FLU), dacarbazine (DTIC), Adriamycin, and only a few other options. As a follow-up to the nurses' research, a group of research oncologists therefore decided to identify patients and ask them to participate in a 5-year survival study utilizing DTIC. The study started with 80 patients. Between the first and second years (full-year 1), 0 patients had died but 4 were censored. Between the second and third years (full-year 2), 2 patients had died and 0 were censored. Between the third and fourth years (full-year 3), 0 patients had died and also 0 were censored. Between the fourth and fifth year (full-year 4), 32 patients had died and 0 were censored. Between the fifth and sixth years (full-year 5), 6 more patients died yet 0 were censored.
