Chemotherapy
- systemic treatment with a variety of chemical
agents
- is commonly used to treat patients with lymphomas and other cancers.
For lymphomas, chemotherapies are often particularly effective.
Chemo-protective:
a quality of some drugs, foods, or lifestyles that may protect
healthy tissue from the toxic effects of anticancer drugs, or carcinogens
in the environment.

Chemo-enhancement: a property
of some drugs, foods, or lifestyles that may increase the
effectiveness of anticancer drugs by increasing uptake of the
drugs into cancer cells, or making the cells more sensitive to the
effects.
Note: it is always possible that interventions with
chemo-protective & -enhancing properties may have unintended
adverse consequences when used when receiving treatments. Only
well- designed clinical trials can provide the data for informed
use.
IMPORTANT: Discussion of the use of
supplements with your physicians is particularly important when
undergoing treatment.
The purpose of this page is to provide links to
reputable sources of information on practices that may protect them
from side effects and/or enhance the effects of chemotherapy. We
hope the summary and sources will assist patients in consultations
with their doctors to make better-informed decisions.
Biologics:
Biologics,
with trade names such as Neumega®,
Neupogen®, and Procrit®
can help to restore blood counts, and protect you from many side
effects associated with chemotherapy. Importantly, these new
therapies can help to keep you on treatment schedule, which could be
important to how effective your treatment will be.

Antioxidants?
Antioxidants use with chemotherapy is a
controversial subject.
Please consult with your physician before self-administering antioxidants
or any supplement, especially during treatment.
|
Some recent studies suggest that antioxidants
may enhance chemotherapy; and that oxidative stress can interfere with
chemotherapy induced apoptosis. Importantly, high doses of one
antioxidant, Vitamin C, results in oxidative effects (opposite
of antioxidant). This adds to the complexity and confusion for
both patients and physicians.

Fish Oil?
|
There is some scientific data suggesting that supplementing with fish oil (docosahexaenoic and eicosapentaenoic
acids) might enhance the efficacy of some chemotherapy agents and that
it might protect against some side effects..
CAUTION: Fish oil consumption may increase the
risk of bleeding in susceptible individuals, and interactions with
other chemotherapy agents is not well known.
|
Glutamine
Whey Protein?
|
Glutamine may compliment chemotherapy and lessen side effects.
CAUTION: Glutamine might stimulate the
growth of some types of malignant cells, therefore it may not be wise
to supplement with this amino acid during watch & wait status.
