Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Histologic yield	The rate of samples containing a tissue "core" (yes/no) for histological evaluation, defined as an intact piece of tissue of at least 550 µ	6 months
Secondary	Tissue integrity	Tissue integrity will be evaluated by attributing a score from zero to 3 (3 represents the better outcome), according to the following score system: 0: No cells/tissue; Cytological specimen (disaggregated cells representative of the target lesion not allowing for tissue architectural assessment); Histologic microfragments (sample adequate for histological evaluation, namely an architecturally intact piece of tissue but without a "core"); Histologic "core" (defined as an architecturally intact piece of tissue measuring at least 550 µ)	6 months
Secondary	Blood contamination	Blood contamination will be evaluated by attributing a score from zero to 3 (3 represents the better outcome), according to the following score system: 0: Only blood; High blood contamination (>50% of the surface); Moderate blood contamination (25-50% of the surface); Low blood contamination (<25% of the surface)	6 months
Secondary	Tumor fraction	The rate of samples containing an adequate tumor fraction =20 percent (i.e., = 20 percent tumor cells in a background of benign nucleated cells).	6 months
Secondary	Diagnostic accuracy	Diagnostic accuracy (defined as the ratio between the sum of true positive and true negative values divided by the number of lesions) will be calculated for each study arm	6 months
