Characteristics of patients with soft tissue tumors.
| Characteristics | Healthy volunteers (10) | Benign (48) | STS (87) | p-value | |
|---|---|---|---|---|---|
| Sex | Male | 2 | 25 | 47 | *0.126 |

| Age | Average (SD) | 51.4 (12.5) | 54.2 (13.7) | 63.4 (15.1) | #P < 0.001 |
| sPD-L1 | Average (SD) | 34.2 (10.3) | 46.6 (24.7) | 61.7 (58.2) | #0.017 |
| Characteristics in benign and STS patients | N (135) | sPD-L1 average(SD) | p-value | ||
| Sex | Male | 72 | 55.0 (31.7) | **0.095 | |
| Female | 63 | 57.7 (64.4) | |||
| Age | ≤60 y | 61 | 48.4 (28.3) | **0.228 | |

| History of other malignant tumors | − | 111 | 54.3 (36.1) | **0.324 | |
| + | 24 | 65.3 (88.4) | |||
Sex, age, malignancy, and sPD-L1 values were evaluated by *Fisher’s exact test and the #Kruskal-Wallis test (upper table). sPD-L1 values were compared for each parameter by the **Mann-Whitney test (lower table).
