Hoewel botkanker in de vorm van multiple myeloma - ziekte van Kahler meestal voorkomt bij ouderen worden soms ook jong volwassenen getroffen door deze ziekte.  

Oren Pasvolsky, M.D. en collega's van het MD Anderson Cancer Center van de Universiteit van Texas in Houston voerden een retrospectief overzicht uit om de resultaten te analyseren voor 117 jongere patiënten met een mediane leeftijd van 37 jaar (bereik, 22 tot 40 jaar) die een autologe-stamceltransplantatie (auto-HCT) ondergingen voor multiple myeloma - ziekte van Kahler in het MD Anderson Cancer Center zelf.

Hier de resultaten uit het studierapport vertaald:

  • De onderzoekers zagen dat vóór de autologe-stamceltransplantatie (auto-HCT) 10 procent van de patiënten ten minste een volledige remissie (≥CR) bereikte en 44 procent ten minste een zeer goede gedeeltelijke remissie (≥VGPR).
  • Voor de beste remissie na transplantatie behaalden 56 en 77 procent van de patiënten respectievelijk een complete remissie (≥CR) en een zeer goede gedeeltelijke remissie (≥VGPR). De mediane ziekteprogressievrije tijd (PFS) en overall overleving (OS) waren respectievelijk 43,1 en 146,6 maanden.
  • In vergelijking met eerder getransplanteerde patiënten hadden patiënten die na 2010 een autologe-stamceltransplantatie (auto-HCT) ondergingen een betere mediane ziekteprogressievrije tijd (PFS) (84,9 versus 28,2 maanden) en mediane overall overleving (OS) (niet bereikt versus 91,8 maanden).
  • Het bereiken van een complete remissie (≥CR) als beste remissie na de autologe-stamceltransplantatie (auto-HCT) was geassocieerd met verbeterde ziektevrije tijd (PFS) (hazard ratio, 0,55); het bereiken van een zeer goede gedeeltelijke remissie (≥VGPR) was voorspellend voor superieure overall overleving (OS) (hazard ratio, 0,32).
Volgens de onderzoekers hadden jongere patiënten met multiple myeloma - ziekte van Kahler een duurzame overleving na een autologe-stamceltransplantatie (auto-HCT), die verder verbeterde na de beschikbaarheid van nieuwe anti myelomageneesmiddelen in de afgelopen jaren".

Summary

Multiple myeloma (MM) primarily affects older patients. There are scarce data on the outcomes of young adults undergoing autologous transplantation (auto-HCT). In this single-centre analysis, we included 117 younger patients, with a median age of 37 years (range 22–40) at transplant. Seventeen (15%) patients had high-risk cytogenetics. Before transplant, 10% of patients achieved ≥CR and 44% achieved ≥VGPR. At best post-transplant response, 56% and 77% of patients achieved ≥CR and ≥VGPR respectively. With a median follow-up for survivors of 72.6 months (range 0.9–238.0), median PFS and OS were 43.1 months (95% CI 31.2–65.0) and 146.6 months (95% CI 100.0–208.1) respectively. Patients who underwent auto-HCT after 2010 had better median PFS (84.9 months vs. 28.2 months, p < 0.001) and OS (NR vs. 91.8 months, p < 0.001) compared with those transplanted earlier. In multi-variate analysis, achieving ≥CR as best post-transplant response was associated with improved PFS (HR [95% CI] 0.55 [0.32–0.95], p = 0.032), while achieving ≥VGPR was predictive of superior OS (0.32 [0.16–0.62], p < 0.001). Three patients (3%) developed a second primary malignancy. Younger MM patients had durable survival after auto-HCT, which further improved after the availability of novel anti-myeloma drugs in recent years. Depth of response following transplant remains a key predictor of survival.
