Occult tumor cells are frequent in apparently tumor-free lymph nodes of pancreatic cancer patients and often overlooked in conventional histopathology. They are encountered even in limited stages of disease and they impair prognosis, which is comparable to that of patients with true lymphatic metastases. Occult tumor cells in lymph nodes of pancreatic cancer patients could be used to stratify adjuvant therapy.
ITCs detected by the antiepithelial antibody Ber-EP4 are present in a substantial proportion of apparently tumor-free lymph nodes. These cells impair patients' prognoses, irrespective of the underlying cell morphology. As approximately one third of Ber-EP4-positive cells in p53-positive primary tumors do not overexpress p53; their true tumorigenic origin needs to be further investigated.
Mesh wrapping hepatorrhaphy is an established method to control severe hepatic bleeding after trauma. Besides the multiple advantages of this technique, only a few complications are described in literature. We report a patient with severe liver trauma showing ischemia of the liver caused by post-traumatic edema and compression of the liver after mesh wrapping hepatorraphy to control the bleeding. To avoid this complication, early and frequent control of liver enzymes is highly recommended and, in case of elevation, laparotomy and decompression should be performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
