text: Yo, check it out, here's the deal,
  A study went down in 32 places, real,
  All across the nation, evaluating the scene,
  Recombinant human leukocyte A interferon, know what I mean?
  
  They called it rIFN-alpha A, Ro 22-8181,
  Testing its clinical efficacy, havin' some fun,
  On malignant tumors in the urogenital tract,
  Gotta see if this treatment can counteract.
  
  They used the criteria proposed by Koyama and Saito,
  To evaluate the responses, yo, that's how they go,
  Out of 269 cases they checked in the game,
  Only 138 cases were evaluated, what a shame.
  
  Among 108 cases with renal cell carcinoma,
  They saw some efficacy, no time for drama,
  Complete response in 2 cases, that's real nice,
  Partial response in 13 cases, like rolling the dice.
  
  Bladder cancer had one case with partial response,
  And tumors of the renal pelvis and ureter, no less,
  One case showed some progress, they were glad,
  But overall, the efficacy rate was 13.9%, not bad.
  
  Now let's talk about the side effects they found,
  Fever, malaise, anorexia, nausea, goin' round,
  These were the subjective and objective issues they saw,
  But when they stopped the treatment, it was no more.
  
  Lab tests showed leukopenia, thrombocytopenia too,
  Elevation of GOT X GPT, things were askew,
  But don't worry, these abnormalities did fade,
  When they stopped the rIFN-alpha A or gave the right grade.
