Results:

We examined 15 upper abdominal lesions from 11 patients (8 male, 3 female). The median age at diagnosis was 75 years (range: 52-92 years). The primary tumor was hepatocellular carcinoma in 3 patients, pancreatic cancer in 3 patients, lung cancer in 2 patients, colon-rectal cancer in 2 patients and kidney cancer in 1 patient. The upper abdominal lesions were located in the liver and in the pancreas in respectively 12 and 3 cases. The median number of lesions per patient was 1 (1-3). Median ΔPTV, ΔCC, ΔLL and ΔAP were respectively 9.11 cc (-135.54-49.34 cc, p=0.0076), 3 mm (-2.7-8.9 mm, p=0.0037), 2.2 mm (0.5-9.9 mm, p=0.00064) and 2.2 mm (0.5-6.8 mm, p=0.00064). Results are summarized in Table 1.
