Northeast Radio SD News - Watertown, SD - After a physically and emotionally grueling holiday season, the family of six-year-old Miriam Koska is celebrating a significant victory in her fight against metastatic neuroblastoma. Emily Koska shared in a recent update that Miriam completed a stem cell harvest this week, yielding results that far exceeded medical expectations.
The milestone comes after a series of setbacks for the family, who have roots in Watertown. Miriam was discharged from Sanford on Dec. 16 after a four-night stay for a fever. While blood cultures remained negative, the family had to wait for her counts to recover before moving forward with the next stage of treatment.
A Solo Journey to the Twin Cities
Illness within the household added further complications just as the family prepared to travel to the Twin Cities. With both her son, Abram, and husband, Mike, developing fevers, Emily Koska—who is currently in her third trimester of pregnancy—was forced to make the drive and manage the hospital admission alone.
“There were lots of tears on that drive thinking about how hard the next few days might be in a new hospital by myself in my third trimester while caring for Miriam,” Emily stated.
“Excellent” Harvest Results
Miriam was admitted to the University of Minnesota Fairview on Dec. 22. The process proved physically demanding, as Miriam struggled with severe bone pain caused by growth factor injections and discomfort from a temporary central line. Despite a brief complication involving a kinked line that required repositioning, the apheresis procedure on Dec. 23 was a resounding success.
While medical staff set a collection goal of 25, Miriam’s body produced a count of 75—the highest the team had seen in quite some time. The exceptional result meant Miriam did not have to undergo any further harvest sessions and could return home for Christmas.
Current Status and Continued Battle
The reprieve was short-lived, as Miriam was admitted back to Sanford on Dec. 26 to begin her third round of chemotherapy. This round carries significant concerns regarding potential toxicity, including risks of hearing loss and kidney damage. The family anticipates a three-night stay with a planned discharge on Monday, Dec. 29.
