Diagnostic Tests for Mediastinal Sarcoma

Mediastinal sarcomas are rare and aggressive tumors that can be challenging to diagnose. Various diagnostic tests can help identify these tumors, and the choice of test depends on the appearance of the tumor on imaging studies.

• Blood Tests: Blood tests may include Alpha-fetoprotein (AFP), beta HCG, and LDH levels. These tests can help identify potential biomarkers for mediastinal sarcomas [1].
• Tissue Biopsy: A tissue biopsy is a crucial diagnostic test for mediastinal sarcomas. It involves taking a sample of tissue from the tumor using a CT-guided needle biopsy or fine-needle aspiration cytology (FNAC) [3, 5]. This test can provide valuable information about the tumor's cell morphology and molecular characteristics.
• Imaging Studies: Imaging studies such as Chest X-ray, Computed Tomography (CT) scan, and Magnetic Resonance Imaging (MRI) can help identify mediastinal sarcomas. These tests can also guide the choice of biopsy technique [4, 8].
• Fine-needle Aspiration Cytology (FNAC): FNAC is a minimally invasive diagnostic test that involves using a fine needle to collect cells from the tumor. This test can provide valuable information about the tumor's cell morphology and molecular characteristics [3, 5].
• Core Needle Biopsy: Core needle biopsy involves taking a small sample of tissue from the tumor using a larger needle than FNAC. This test can provide more detailed information about the tumor's histology and molecular characteristics [6].
