Brief summary

TGCT is a rare disease that is difficult to manage, surgical resection is the primary treatment currently available. To date no disease registry exists and there is little data available detailing the management of patients with diffuse TGCT (d-TGCT), the burden of d-TGCT for patients (including pain, joint stiffness, swelling, reduced mobility and quality of life) or the economic impact of d-TGCT. This study aims to collect data by an observational disease registry involving no intervention to the patient or changes to investigators treatment decisions.

Detailed description

GCT is a rare, benign, but potentially locally aggressive and recurrent disease. Treatment pattern and treatment initiation, continuation or changes are solely at the discretion of the physician and the patient. There will be no attempt to influence the prescribing patterns of any individual treating physician. All medication will be prescribed in the usual standard of care and will not be provided by the study sponsor. Participation in the study will in no way influence payment or reimbursement for any treatment received by patients during the study. It is the responsibility of the investigator and his study staff to enter all relevant patient data required for this registry in the electronic Case Report Form (eCRF) and in the patients' medical records. Approximately 15 sites from up to 6 European Countries (France, Germany, Italy, The Netherlands, Spain and United Kingdom) and 4 sites from the US are planned to participate. The sites will be specialized sites that treat d-TGCT regularly.

MeasureTime frameDescription
Mean PROMIS Physical Function Score From Baseline Through 24 MonthsBaseline up to end of observation period (approximately 2 years)PROMIS® (Patient-Reported Outcomes Measurement Information System) is a set of person-centered measures that evaluates and monitors physical, mental, and social health. Physical function scores range from 0 (worst physical function) to 100 (best physical function, where higher scores indicate better clinical outcome.
Time Since Most Recent Tumor Recurrence Until Baseline in Patients With Diffuse TGCT (d-TGCT)at BaselineTime since most recent tumor recurrence was collected from information routinely recorded in the patient files / medical records.
Time From Baseline to First Tumor Recurrence in Patients With Diffuse TGCT (d-TGCT)Baseline up to end of observation period (approximately 2 years)Time from baseline to first tumor recurrence was collected from information routinely recorded in the patient files / medical records.
Mean Brief Pain Inventory (BPI) Pain Severity and Interference Score From Baseline Through 24 MonthsBaseline up to end of observation period (approximately 2 years)The BPI short form is a self administered questionnaire that assesses severity of pain, impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. The BPI pain severity and interference score ranges from 0 (pain does not interfere) to 10 (pain completely interferes), where lower scores indicate better clinical outcome.
Mean Worst Stiffness Score From Baseline Through 24 MonthsBaseline up to end of observation period (approximately 2 years)The Worst Stiffness numerical rating scale (NRS) is a one-item self-administered, patient-reported outcome questionnaire assessing the worst stiffness in the last 24 hours. The NRS for this item ranges from 0 (no stiffness) to 10 (stiffness as bad as you can imagine), where lower scores indicate better clinical outcome.

Tumor severity classification was based on MRI. In this classification scheme, moderate diffuse TGCT is characterized by intra- and/or extra-articular disease, without or with involvement of muscle/tendinous tissue/ligaments. Severe diffuse TGCT is characterized by intra- and extra-articular involvement and involvement of at least one of the 3 structures (muscle/tendinous tissue/ligaments).
Number of Cases With Complications Due to Surgery in Patients With Diffuse TGCT (d-TGCT)at Baseline (prior to any d-TGCT therapy)Complications due to surgery were collected from information routinely recorded in the patient files / medical records.

MeasureTime frameDescription
Mean Number of General Practitioner, Specialist, or Physical Therapy Visits to Assess the Health Resource Utilization in Patients With Diffuse TGCT Through 24 Months13-24 months before baseline up to end of observation period (approximately 2 years)Health resource utilization was assessed by mean number of general practitioner visits, specialist visits, and physical therapy sessions. In addition, the mean number of days in rehabilitation and the number of work days missed were also reported.
Median Number of Days in Rehabilitation and Work Days Missed in Patients With Diffuse TGCT Through 24 Months13-24 months before baseline up to end of observation period (approximately 2 years)The median number of days in rehabilitation and the number of work days missed were also reported.

Mean EuroQol Questionnaire (EQ) of 5 Dimensions (5D) Index Score and EQ Visual Analog Scale Score From Baseline Through 24 MonthsBaseline up to end of observation period (approximately 2 years)The EQ-5D-5L questionnaire measures the patient's quality of life (QoL) based on the 5 dimensions mobility, self care, usual activities, pain/discomfort, and anxiety/depression. The EQ-5D index score ranges from 0 (worst QoL) to 1 (best QoL), where lower scores indicate worse clinical outcome. The EQ-5D VAS reports patient's self rated health ranging from 0 (worst health) to 100 (best health you can imagine), where lower scores indicate worse clinical outcome.

Mean Number of General Practitioner, Specialist, or Physical Therapy Visits to Assess the Health Resource Utilization in Patients With Diffuse TGCT Through 24 Months

Health resource utilization was assessed by mean number of general practitioner visits, specialist visits, and physical therapy sessions. In addition, the mean number of days in rehabilitation and the number of work days missed were also reported.

Time frame: 13-24 months before baseline up to end of observation period (approximately 2 years)

Population: Health resource utilization was assessed in participants with available data in the Full Analysis Set.

Median Number of Days in Rehabilitation and Work Days Missed in Patients With Diffuse TGCT Through 24 Months

The median number of days in rehabilitation and the number of work days missed were also reported.

Time frame: 13-24 months before baseline up to end of observation period (approximately 2 years)

Population: Number of days in rehabilitation was assessed in the Full Analysis Set. A participant could have documented days in rehabilitation for the 1st year visit as well as for the 2nd year visit which resulted in a sum greater than the single results per visit/year.
