Reasons for Delay in Time to Initiation of Adjuvant Chemotherapy for Colon Cancer.

Purpose: Adjuvant chemotherapy (AC) improves survival among patients with colon cancer (CC). Two meta-analyses have demonstrated a decrease in survival with increasing time to AC (TTAC). Here, we examine the predominant factors leading to delay in TTAC.

Factors influencing the yield of mesenteric angiography in lower gastrointestinal bleed.

Aim: To assess if certain triaging rules could be established to optimize the yield of mesenteric angiography.

Methods: Medical records of 101 patients were retrospectively reviewed and parameters relating to age, gender, pulse rate, blood pressure, serum hemoglobin, intensive care unit (ICU) admission, and the number of packed red blood cells (PRBC) transfused in the 12 and 24 h prior to the angiography were tabulated in two groups with positive and negative angiography results.

Results: We found no correlation between gender, pulse rate, blood pressure or serum hemoglobin and positivity of the mesenteric angiogram.
