Is the location of lymphangiogenesis an independent prognostic factor in rectal cancers with or without preoperative radiotherapy?
LVD at the periphery of the tumour was an independent prognostic factor in rectal cancer patients.
Dual-phase F-FDG PET/CT is not useful in characterizing pancreatic masses as it cannot differentiate benign from malignant lesions, and focal uptake on early PET imaging is the best indicator of malignancy. A possible benefit in performing a delayed scan is that a high RI (>18.7) can predict poor survival and hence may be useful in treatment planning.
