Does tumor-associated lymphangiogenesis correlate with lymph node metastases and prognosis in hilar cholangiocarcinoma?
Lymphangiogenesis is associated with increased frequency of tumor cells in lymphatics and lymph nodes in hilar cholangiocarcinoma. The prognostic importance of tumor-associated lymphangiogenesis was reflected by LVD serving as an independent prognostic factor. In addition, lymphangiogenesis may represent a potential target in the development of new therapeutic approaches in hilar cholangiocarcinoma.
Some children with intractable chronic constipation have rapid proximal colonic transit, have symptoms consistent with possible food allergy/intolerance, and may respond to dietary exclusion. The NTS can identify these patients with rapid proximal transit that may be secondary to food intolerance.
