Tenosynovial Giant Cell Tumors (TSGCTs) - Market Insight, Epidemiology, and Market Forecast - 2036

Tenosynovial Giant Cell Tumor (TGCT) Insights and Trends

• According to DelveInsight's analysis, TGCT market size was found to be ~USD 326 million in the leading markets (the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan) in 2025.
• TGCT are caused by a translocation of certain parts of chromosomes 1 and 2 causing the cells to overproduce a protein called colony-stimulating factor-1 or CSF-1. There are no environmental, genetic, occupational, lifestyle, demographic or regional risk factors that have been conclusively shown to be involved with the development of these tumors.
• TGCT have a wide clinical spectrum that affect patients of all ages. The signs and symptoms of tenosynovial giant cell tumor (TGCT) can vary depending upon the exact location involved and the subtype present.
• TGCT occurs in localized and diffuse forms and typically presents as a well-defined, rubbery, multinodular mass surrounded by a fibrous capsule. The cut surface shows variable coloration based on the relative amounts of fibrous tissue, hemosiderin, and lipid-laden macrophages. Clinically, patients often present with a slow-growing, painless swelling that may later become painful or edematous, commonly causing intermittent knee swelling.
• Localized TGCT grows slowly and usually affects small joints, particularly the fingers and tendon sheaths, and is often referred to as giant cell tumor of the tendon sheath (GCTTS). Diffuse TGCT grows more aggressively and typically involves large joints such as the knee, hip, ankle, shoulder, or elbow, and is also known as pigmented villonodular synovitis (PVNS). TGCT is rarely seen in the head and neck region.
• Historically, TGCT has been treated primarily with surgical synovectomy, using arthroscopic or open techniques, sometimes combined with adjuvant radiotherapy. Localized disease is generally curable with surgery, while diffuse TGCT is associated with high recurrence rates. Open surgical approaches in diffuse disease can lead to increased morbidity, including postoperative stiffness and pain.
• The diagnosis of TGCT is based on a description of the symptoms and physical examinations. In addition, magnetic resonance imaging (MRI) is usually necessary in order to see the lesions and determine the best surgical intervention. Other tests that may help with the diagnosis include X-rays, synovial fluid sample from around the joints, and a biopsy of tissues from the joint.
• Surgical resection continues to be the mainstay of treatment for patients with localized and diffused TGCT. The significant rates of recurrence and risks associated with surgery point to the need for novel systemic treatments for patients with symptomatic advanced TGCT. The recent approval of a systemic therapy for selected adults with symptomatic TGCT underscores the need for improved and more coordinated multidisciplinary care.

Tenosynovial Giant Cell Tumor (TGCT) Understanding and Treatment Algorithm

Tenosynovial Giant Cell Tumor (TGCT) Overview and Diagnosis

EGFR is a protein in cells that helps them grow. A mutation in the gene for EGFR can make it grow too much, which can cause cancer. There are different types of EGFR mutations, including deletions or insertions and point mutations. In test results, individuals may be identified as having an EGFR 19 deletion or an EGFR L858R point mutation, which are the most common types of EGFR mutations. These mutations are typically treated the same way. Amongst the EGFR mutations that are tested for in lung cancer, a few rare types are treated differently than the more common EGFR mutations. The major example of this in lung cancer is EGFR exon 20 insertions. This is a type of EGFR mutation that does not respond to the typical treatment for EGFR-positive lung cancer, which are called tyrosine kinase inhibitors, or TKIs.

In general, there are two ways to detect EGFR mutations. The best way is through comprehensive next-generation sequencing (NGS). This type of testing places tissue from a patient's tumor (gathered from a biopsy) in a machine that looks for a large number of possible biomarkers at one time. There may be some situations where a patient cannot undergo the biopsy needed to perform NGS, so liquid biopsy is recommended. A liquid biopsy can look for certain biomarkers in a patient's blood.

Current Tenosynovial Giant Cell Tumor (TGCT) Treatment Landscape

Treatment of Tenosynovial Giant Cell Tumor (TGCT) primarily involves surgery and targeted systemic therapies, depending on disease type and severity. Surgical excision or synovectomy remains the mainstay, particularly for localized TGCT, while diffuse or unresectable cases often require systemic treatment. Targeted therapies inhibiting the CSF1/CSF1R pathway, such as pexidartinib and vimseltinib, are the only approved options and have significantly improved outcomes by reducing tumor burden and alleviating symptoms. In select cases, off-label tyrosine kinase inhibitors like imatinib and sunitinib may also be used. Additionally, radiation therapy and supportive care can be considered based on disease progression, recurrence risk, and functional impairment.

Tenosynovial Giant Cell Tumor (TGCT) Epidemiology

Key Findings from TGCT Epidemiological Analysis and Forecast

• According to DelveInsight's estimates, the total number of incident cases of TGCT in the 7MM was nearly 580,000 cases in 2025 and is projected to increase during the forecasted period.
• The total number of prevalent cases of TGCT in the United States was nearly 250,290 in 2025.
• The gender-specific prevalent population of TGCT is segregated based on the tumor's growth pattern, i.e., localized and diffused form. In the United States, ~77,920 males and ~120,782 females had localized TGCT in 2025. On the other hand, in diffused form there were ~24,170 and ~27,400 cases of males and females, respectively, in 2025.
• The giant cell tumors are detected in the knee, ankle, hip, and other depending upon localized or diffused. DelveInsight has estimated tumor localization of diffused TGCT to be maximum in the knee, with nearly 33,010 cases in 2025 in the United States, which might reach nearly 58,110 cases by 2036.
• TGCT most commonly occurs in large joints, with the knee being the most frequently affected site, followed by the hip, ankle, and shoulder. Localized TGCT often involves smaller joints such as the fingers, hands, and wrist, typically arising from the tendon sheath. In contrast, diffuse TGCT more commonly affects larger, weight-bearing joints and is associated with extensive synovial involvement. The distribution of disease is largely driven by synovial tissue presence rather than external risk factors, with no strong geographic variation reported.

Approved Therapies for TGCT

TURALIO (Pexidartinib): Daiichi Sankyo

TURALIO (Pexidartinib, formerly PLX3397) is an orally administered small molecule tyrosine kinase inhibitor that targets Colony-stimulating Factor 1 Receptor (CSF1R), KIT proto-oncogene receptor tyrosine kinase (KIT), and FMS-like Tyrosine Kinase 3 (FLT3) harboring an Internal Tandem Duplication (ITD) mutation. Overexpression of the CSF1R ligand promotes cell proliferation and accumulation in the synovium. In vitro, pexidartinib inhibited the proliferation of cell lines, which is dependent on CSF1R and ligand-induced auto-phosphorylation of CSF1R. Pexidartinib also inhibited the proliferation of a CSF1R-dependent cell line in vivo. It is a kinase inhibitor indicated for the treatment of adult patients with symptomatic TGCT associated with severe morbidity or functional limitations and not amenable to improvement with surgery. TURALIO was discovered by Plexxikon Inc., the small molecule structure-guided R&D center of Daiichi Sankyo.
