TGCT can be a lifelong condition with long-term impacts resulting from both the disease and treatments1-3

TGCT can have a major impact on
QOL and physical function2

Symptoms commonly reported by patients included:

  • An elbow experiencing pain
    OVER 90%
    HAD PAIN4*
    457 out of 497 patients
  • A leg showing range of motion
    85% HAD LIMITED
    RANGE OF MOTION (ROM)4*
    423 out of 497 patients

*Results from an international, observational, prospective registry of 497 patients initiated in 2022 by TGCT Support, a program of The Life Raft Group.4

QOL=quality of life.

Persistent disease may cause cartilage destruction and bone erosion, in addition to functional limitations from the tumor mass, resulting in long‑term pain and joint dysfunction.5

In a multicenter, retrospective cohort study including 45 patients with diffuse TGCT who did not have osteoarthritis at baseline6:

A joint experiencing stiffness

18% DEVELOPED RADIOLOGICAL SIGNS OF JOINT DEGENERATION6

8 out of 45 patients

While surgical resection is considered the standard of care, it is not always curative2,7

Up to72%Recurrence

has been reported after
resection in diffuse TGCT4

  • There are risks and limitations associated with TGCT surgical resection3,7
  • Repeated surgical resections can lead to increased morbidity, including acceleration of secondary osteoarthritis, permanent joint damage, and other lifelong consequences3,7

Repeated surgeries and multiple recurrences can turn TGCT into a chronic, lifelong condition.1,2

“Patients with TGCT require long‑term treatment and need therapeutic options that can improve the symptoms of TGCT... with manageable toxicity profiles.”8
