Intravenous hyperalimentation as an adjunct to radiation therapy
Cancer
|February 1, 1977
Summary
Intravenous hyperalimentation (IVH) enabled malnourished cancer patients to complete radiation therapy. Nutritional support correlated positively with tumor response and weight gain, improving outcomes.
Area of Science:
- Oncology
- Nutritional Science
- Radiotherapy
Background:
- Radiation therapy can cause anorexia and weight loss, limiting treatment efficacy.
- Nutritionally-depleted cancer patients often face challenges completing radiation therapy.
- Intravenous hyperalimentation (IVH) is a nutritional support method for patients unable to maintain adequate oral intake.
Observation:
- 39 malnourished cancer patients received radiation therapy with concurrent IVH.
- The average radiation dose was 3827 rads over 3.5 weeks.
- 95% of patients completed their planned radiation therapy course.
Findings:
- Patients receiving IVH and radiation therapy showed significant symptomatic improvement.
- 54% of patients experienced >50% tumor size reduction.
- Responding patients gained an average of 13.0 lbs, compared to 4.9 lbs in non-responders (p<0.001).
- Serum albumin increased significantly in responders but not in non-responders.
Implications:
- IVH facilitates the delivery of planned radiation therapy doses in malnourished, high-risk cancer patients.
- Improved nutritional status is positively correlated with tumor response to radiation therapy.
- IVH is a valuable adjunct for managing complications like enteric fistulas in patients undergoing radiation therapy.
