Detailed Description
This prospective pilot study is designed to investigate the uptake of dietary fructose and xylose by primary human colon tumors. In this study, the recruited patients with colorectal cancer will receive an oral sugar solution containing either Fructose sugar or Xylose sugar before surgery. The tumor will then be resected and a portion of the tumor, normal intestinal tissue, blood, urine, and liver will be used to quantify fructose and xylose.
- Research question Can primary human tumors take up fructose or xylose?
- A statement of the hypothesis The hypothesis is that fructose, but not xylose, can be directly absorbed and stored by primary human colon tumors.
- Design Prospective, non-randomized, pilot, feasibility, single-center, open-label, phase 1, investigator-initiated study to evaluate the uptake of dietary fructose and xylose by primary human colon tumors with 12 subjects in 2 cohorts: Cohort 1: 6 subjects will consume a sugar solution containing fructose and Cohort 2: 6 subjects will consume a sugar solution containing xylose. Eligible subjects that are scheduled to undergo colorectal resection for cancer treatment will be invited to participate in the study in consecutive order from the practice of colorectal surgeons at the time of their preoperative clinic visit. First, Cohort 1 subjects will be enrolled followed by the Cohort 2 subjects.

Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Subjects of 18 years of age or older, male, and female
- Subjects with a diagnosis of invasive non-hereditary colonic adenocarcinoma who will be undergoing standard of care (SOC) laparoscopic, robot-assisted, or open surgical resection
- The subject provides informed consent
Exclusion Criteria:

---|---|
Experimental: Cohort 1: HFCS (fructose-fed)
Day Before Surgery between 09:00 pm and 10:00 pm Subjects will prepare the sugar solutions (Fructose-containing solution: 250 mL of water containing 41.25 g of D-Fructose and 33.75 g of D-Glucose) by adding 250 ml water to the sugar powder provided by the study team and drink it between 09:00 pm and 10:00 pm. Subjects will be reminded the day before the surgery to drink the solution. |
