Vitamin D during early colon cancer or liver surgery
Treatments studied
Part of Cancer, Digestive system clinical trials.
This trial studies whether taking higher-dose vitamin D3 around the time of colon cancer (or colon cancer with resectable liver metastases) surgery improves outcomes. It focuses on safety and possible effects on cancer-related health after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older.
- You have confirmed colon cancer that is either early stage (stage I–III) or has liver metastases that can be removed with surgery.
- You can have the planned surgery as your main treatment, and for early-stage colon cancer you have not had radiation or whole-body (systemic) cancer treatment beforehand.
- For people having liver surgery: your last chemotherapy/radiation must be at least 4 weeks (and bevacizumab at least 6 weeks) before surgery.
- You should not already take high-dose vitamin D (2,000 IU/day or more) in the past year, and you must be able to swallow study pills; you also must not have trouble absorbing medicine due to gut problems.

This trial studies whether giving a higher dose of vitamin D3 helps children and teens with inflammatory bowel disease (Crohn’s or ulcerative colitis) who have low vitamin D levels. Participants are already on biologic medicines and will be treated while monitoring blood (and safety) related to vitamin D.
This study looks at whether vitamin D levels affect recovery and health after liver cancer surgery. Participants will receive a high-dose vitamin D supplement before surgery to see if it helps improve outcomes and reduce healthcare disparities.
This trial tests whether taking vitamin D pills during chemotherapy or targeted therapy (before breast cancer surgery) can improve how well the treatment works and reduce side effects. It is for women with low vitamin D levels.
This study tests whether taking high-dose vitamin D before and during chemotherapy helps eliminate more cancer before surgery in people with triple-negative breast cancer who are low in vitamin D.
This trial tests whether taking vitamin D supplements can reduce side effects from chemotherapy in people with breast cancer. It is for patients with low vitamin D levels who are about to start their first chemotherapy treatment.
This study looks at how vitamin D levels affect treatment results in women with locally advanced cervical cancer who are about to start chemoradiation (chemotherapy plus radiation). It aims to see if higher vitamin D is linked to better outcomes.
