Pathology Report: neuroendocrine neoplasm; atypical carcinoid (AC) [mild cellular pleomorphism, necrosis, 3 mitoses/2 mm 2, chromogranin +, NSE +, CD 56 +, CK8/18+]

6/2009 up to 7/2012: follow up

7 /2012: scheduled upper abdomen MRI: at least 22 new lesions with a maximum diameter about 1.5 cm in the left, right and caudate liver lobe, with abnormal signal intensity and contrast agent uptake.

10/2012: patient was admitted to the clinic for diagnostic workout and further treatment planning. – NSE, CA19-9, CEA, urine-5-HIAA: normal – Chromogranin: 108 ng/ml (normal values: in serum , in plasma ) Due to their small size the liver lesions could not be biopsied under CT scan and a laparoscopic liver biopsy could not be done 11/2012: Octreoscan: diffuse abnormal uptake of the radioactive substance in the liver, which shows hyperexpression of somatostatin receptors, primarily sst 2

11/2012: starts 1 st line chemotherapy with CDDP 80 mg/m 2 and Vepesid 100 mg/m 2

1/2013: 3 rd chemotherapy cycle, good tolerance, CT scan restaging: SD 4 th cycle: exertional dyspnea. Heart U/S: marginally normal dimensions of the heart chambers and E.F. 60%. Strict fluid equilibrium control was advised as well as cardiology follow up before chemotherapy. CDDP was changed with CarboAUC5 from the 5 th cycle.

4/2013: completion of 1 st line chemotherapy Restaging: PD with increase in the dimensions of most of the lesions which are noted in all the hepatic lobes, while one left lobe lesion presents a significant enlargement(4 cm from 1.5 cm)

9/2013: restaging: hepatic lesions remaining, with increase of the dimensions in certain and a decrease in others. Greater enlargement of the left lobe lesion (6 cm from 4 cm)

11/2013: restaging: SD 02/2014: restaging: mild increase of the dimensions in most lesions

04/2014: SD
