Grading of Neuroendocrine Carcinomas: Correlation of ⁶⁸Ga-PET/CT Scan with Tissue Biomarkers

Table 6

Correlation between ⁶⁸Ga-PET/CT or octreoscan and best response to first-line chemotherapy.

	Best response
	Overall		value	Pancreatic		GI
	PD (%)	SD + PR (%)		PD (%)	SD + PR (%)	PD (%)	SD + PR (%)
Overall	3 (30.0)	7 (70.0)		1 (20.0)	4 (80.0)	2 (40.0)	3 (60.0)
^68Ga-PET/CT or octreoscan
Negative	2 (66.7)	4 (57.1)	0.667	0 (0.0)	1 (25.0)	2 (100.0)	3 (100.0)
Positive	1 (33.3)	3 (42.9)		1 (100.0)	3 (75.0)	0 (0.0)	0 (0.0)

PD: progressive disease; SD: stable disease; PR: partial response; GI: gastrointestinal. value was calculated on the overall number of patients.
