Back in 2014, a woman with advanced cancer pushed Adrienne Boire’s scientific life in a whole new direction. The cancer, which had begun in the breast, had found its way into the patient’s spinal fluid, rendering the middle-aged mother of two unable to walk. “When did this happen?” she asked from her hospital bed. “Why are the cells growing there?” Why, indeed. Why would cancer cells migrate to the spinal fluid, far from where they’d been birthed, and how did they manage to thrive in a liquid so strikingly poor in nutrients? Boire, a physician-scientist at Memorial Sloan Kettering Cancer Center in New York, decided that those questions deserved answers.
The answers are urgent, because the same thing that happened to Boire’s patient is happening to increasing numbers of cancer patients. As the ability to treat initial, or primary, tumors has improved, people survive early rounds with cancer only to come back years or decades later when the cancer has somehow resettled in a new tissue, such as brain, lung or bone. This is metastatic cancer, and it’s the big killer—while precise numbers are scarce, anywhere from half to the large majority of cancer deaths have been attributed to metastasis. Offering people more options and hope will mean understanding how those cancers successfully migrate and recolonize.
The prevalence of metastasis belies the arduous journey that cancer cells must make to achieve it.
