Following standard assessments (medical history, physical examination, complete blood count, biochemistry, computed tomography scans of the neck, chest, abdomen, and pelvis, targeted evaluations of all symptomatic areas, pathology, and immunohistochemistry), the diagnosis was determined as a primary site unknown tumor (including adenocarcinoma, squamous cell carcinoma, undifferentiated carcinoma, neuroendocrine carcinoma, sarcoma, etc).\n3.

Complete clinical, pathological, and follow-up data for the patients can be obtained.\n5. ECOG performance status score: 0-2 points.\n\nExclusion Criteria:\n\n1. Pregnant or lactating female patients.\n2. Tumor tissue sample size is too small (tumor tissue accounts for \\\u003C70% in the biopsy or slice tissue).\n3. Organ transplant or history of non-autologous (allogeneic) bone marrow or stem cell transplantation.\n4. History of previous tumors, with the current condition being a recurrent tumor.\n5. Hematological malignancies (excluding lymphoma).\n6.
