Patients in whom surgery was abandoned as a result of PET/CT

	Patient	PET/CT result	CT size*/CA19.9# (other CT findings)	Comments
1	56-year-old female	Low grade uptake in HOP. SUV 3.5. Avid uptake in segment 3 liver metastasis	48 mm 2200	Liver metastasis not seen on standard imaging. Lesion became apparent on CT during palliativechemotherapy
2	82-year-old male	Mild-moderate uptake HOP. SUV 4.9. Moderate uptake in para-aortic lymph node	35 mm 660	Node not seen on prior imaging. Died of metastatic disease 16 months later
3	34-year-old male. Swachman diamond syndrome	Moderate uptake in HOP. SUV 4.7. 2 hepatic metastases	22 mm 140	Subtly visible on CT but PET/CT confirmed metastases. Patient died 8 months later of metastases
4	77-year-old male	Avid uptake HOP. SUV 12.1. 2 peripheral right sided hepatic metastases	30 mm 360	No metastases seen on CT. Died 12 months later of metastatic disease
5	54-year-old male	Avid uptake body of pancreas. SUV 7.77 Avid mediastinal, cervical nodes and multiple bone metastases	20 mm 44 000 (Prominent node right of SMA)	Sclerotic lesions seen on CT but metastases confirmed by PET and subsequently by MRI. Patient died 4 months later
6	75-year-old male	Mild-moderate uptake HOP. SUV 5. Liver (segment 5), para-aortic node and posterior mediastinal node avid uptake consistent with metastases	28 mm 110	Mildly enlarged para-aortic nodes and multiple hepatic cysts seen on CT and MRI. Patient died 2 months later of gastrointestinal haemorrhage
7	47-year-old female	Mild- moderate avidity HOP. SUV 4.5 Low to moderate avidity in peri- pancreatic node. Avid posterior mediastinal lymph node 7 mm size	15 mm 350 (34 mm nodal mass superior to pancreatic head)	Mediastinal node not seen on CT. Thoracoscopic biopsy of node confirmed adenocarcinoma
8	58-year-old female	Avid HOP. SUV 11.5 Avid peri-pancreatic nodes. Avid nodes within mediastinum, lung hilar supraclavicular and cervical nodes	46 mm 10 000 (enlarged 2 cm nodes around pancreas head)	Mildly enlarged nodes in chest/neck on CT (10-13 mm). Excision biopsy of cervical nodes revealed sarcoidosis and adenocarcinoma. Died 4 months later
9	65-year-old male	Avid HOP lesion. SUV 8.1 Moderate uptake segment 2/3 lesion consistent with metastasis	No discrete mass identified. 200 (dilated common bile duct)	Liver metastasis not seen on initial CT but developed on subsequent imaging. Alive with disease 18 months later
