The Emperor of All Maladies: A Biography of Cancer

The treatment protocol that emerged from these guiding principles could only be described as, as one of Pinkel’s colleagues called it, “an allout combat.” To start with, the standard antileukemic drugs were given in rapid-fire succession. Then, at defined intervals, methotrexate was injected into the spinal canal using a spinal tap. The brain was irradiated with high doses of X-rays. Then, chemotherapy was bolstered even further with higher doses of drugs and alternating intervals, “in maximum tolerated doses.” Antibiotics and transfusions were usually needed, often in succession, often for weeks on end. The treatment lasted up to two and a half years; it involved multiple exposures to radiation, scores of blood tests, dozens of spinal taps, and multiple intravenous drugs—a strategy so precise and demanding that one journal refused to publish it, concerned that it was impossible to even dose it and monitor it correctly without killing several patients in the trials. Even at St. Jude’s, the regimen was considered so overwhelmingly toxic that the trial was assigned to relatively junior physicians under Pinkel’s supervision because the senior researchers, knowing its risks, did not want to run it. Pinkel called it “total therapy.”
