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

Table 7

Correlation between histological classification and best response to first-line chemotherapy.

	Best response
	Overall		value	Pancreatic		GI
	PD (%)	SD + PR (%)		PD (%)	SD + PR (%)	PD (%)	SD + PR (%)
Overall	3 (27.3)	8 (72.7)		1 (20.0)	4 (80.0)	2 (33.3)	4 (66.7)
Histological classification
NET G3	2 (66.7)	4 (50.0)	1.000	1 (100.0)	2 (50.0)	1 (50.0)	2 (50.0)
NEC G3	1 (33.3)	4 (50.0)		0 (0.0)	2 (50.0)	1 (50.0)	2 (50.0)

PD: progressive disease: SD: stable disease; PR: partial response; GI: gastrointestinal; NET: neuroendocrine tumor; NEC: neuroendocrine carcinoma. -value was calculated on the overall number of patients.
