Question 1

Chemoprevention is the&#10;A)pharmacologic use of nutrients to suppress or reverse carcinogenesis.&#10;B)pharmacologic use of medications to treat cancer.&#10;C)use of CAM therapy to prevent or treat cancer.&#10;D)reduction of carcinogenic growth factors in the blood.

Accepted Answer

Cancer chemoprevention involves the pharmacologic use of nutrients, such as beta-carotene, selenium, and vitamin E, to suppress or reverse carcinogenesis.Chemotherapy is the pharmacologic use of medications to treat cancer after it develops.Patients may use CAM therapies as additional means of preventing or treating cancer.Immunotherapy stimulates the body's immune system to suppress the growth of cancer cells.

Question 2

Which of the following presents with the symptoms of progressive weight loss, anorexia, generalized wasting and weakness, and immunosuppression?&#10;A)Radiation-induced enteritis&#10;B)Xerostomia&#10;C)Veno-occlusive disease&#10;D)Cancer cachexia

Accepted Answer

Cancer cachexia is a secondary diagnosis in patients with advanced cancer that is similar to protein-energy malnutrition.The patient exhibits progressive weight loss, anorexia, wasting, immunosuppression, altered basal metabolism, and electrolyte and fluid abnormalities.Radiation-induced enteritis is an inflammation of the intestinal tract that can lead to malabsorption.Xerostomia is the sensation of dry mouth, and it can result from chemotherapy, radiation therapy, or surgery involving the mouth.Veno-occlusive disease, or sinusoidal obstructive syndrome, is a potential consequence of bone marrow transplant surgery, chemotherapy, or radiation treatment, which could lead to liver failure.

Question 3

In carcinogenesis, which step does NOT necessarily occur in tumor development?&#10;A)Initiation&#10;B)Promotion&#10;C)Progression&#10;D)Metastasis

Accepted Answer

Metastasis is the process involving the spread of tumor cells to tissues and organs distant from the initial site of development.Not all cancers metastasize, and the discovery of the cancer early in its development can prevent metastasis.Initiation, promotion, and progression are all necessary steps in tumor development.

Question 4

What cautions should be made to a cancer patient considering use of a macrobiotic diet for treatment?&#10;A)It may not provide enough energy and is deficient in calcium and vitamin B12.&#10;B)It may be high in energy, fat, and protein and low in vitamin B12.&#10;C)It may be low in protein and high in energy and fat.&#10;D)It may be high in protein and low in energy and fat.

Accepted Answer

The macrobiotic diet is a quasi-religious vegetarian diet that is nutritionally incomplete.Whole grains provide 50% to 60% of its calories; vegetables provide 25% to 30%; and the remainder of calories comes from beans, seaweed, and soups.Because of a lack of animal protein, calories, calcium, and vitamin B₁₂ are also deficient.

Question 5

Which of the following is a protein that affects fat stores during cancer and induces a state of anorexia?&#10;A)Insulin&#10;B)Growth hormone&#10;C)Tumor necrosis factor (cachectin)&#10;D)Glucagon

Accepted Answer

Tumor necrosis factor is a cytokine protein that promotes breakdown of both protein and fat stores to provide adequate energy for tumor cells.At the same time, an insulin resistance occurs because of the excessive fatty acid oxidation.Glucose levels increase, but the glucose and amino acids made available from protein breakdown are preferentially used by the cancer cells.Growth hormone has been investigated as a potential treatment to promote weight gain in cancer patients who have lost weight.High levels of glucose suppress the secretion of glucagon.

Question 6

Epidemiologic studies have demonstrated most often an association between body weight or BMI and which site-specific cancers?&#10;A)Bladder and lung&#10;B)Breast and prostate&#10;C)Colon, pancreas, and thyroid&#10;D)Esophagus, endometrium, gallbladder, and kidney

Accepted Answer

The most common site-specific cancers that have been positively associated with increased body weight and BMI include the esophagus, endometrium, kidney, and gallbladder.Obesity is associated with increased death rates in 11 types of cancer in men and 12 types in women.

Question 7

Which type of cancer treatment is systemic therapy?&#10;A)Chemotherapy&#10;B)Surgery&#10;C)Radiation therapy&#10;D)Syngeneic hematopoietic stem cell transplant

Accepted Answer

Chemotherapy involves the provision of medications to treat cancer.These medications, however, do not only affect cancer cells because when they are administered, they become distributed throughout the body and are therefore capable of affecting other body cells and systems.Surgery and radiation therapy are generally localized in the treatment of tumors.Although chemotherapy and radiation therapy may be used in conjunction with a syngeneic HSCT, the transplant itself does not involve systems throughout the body.

Question 8

Parenteral nutrition support should be routinely considered&#10;A)for all cancer patients.&#10;B)after hematopoietic cell transplantation (HCT).&#10;C)for well-nourished cancer patients in whom oral intake is about 50% of the desired goal.&#10;D)for patients with advanced cancer whose disease is unresponsive to chemotherapy or radiation.

Accepted Answer

HCT can significantly affect nutrition status.The acute toxicities of immunosuppression include nausea, vomiting, anorexia, and mucositis.Individuals typically have little or no oral intake, and parenteral nutrition has become a standard component of care.Well-nourished patients may be fed orally or enterally.Patients with nonresponsive cancers are more likely to be in the terminal stages of the cancer.In these instances, parenteral nutrition is usually avoided because of high cost and ineffectiveness.If palliative care is implemented, nutrition would be provided as tolerated and desired.

Question 9

Graft-versus-host disease (GVHD)&#10;A)should never be treated with parenteral nutrition.&#10;B)always occurs immediately after transplant.&#10;C)is a minor complication of chemotherapy.&#10;D)is a major complication seen primarily after allogenic transplants.

Accepted Answer

GVHD is a major complication seen after allogenic transplants, in which the donated stem cells react against the tissues of the transplant recipient.It can occur within the first 100 days after transplantation.Symptoms can be severe and include gastroenteritis, abdominal pain, nausea, and vomiting.Parenteral nutrition is often used as Phase I treatment to rest the bowel.

Question 10

An autologous hematopoietic stem cell transplant is one involving&#10;A)stem cells donated by a sibling or parent.&#10;B)stem cells donated by a twin.&#10;C)stem cells previously taken from the patient.&#10;D)stem cells from an unrelated donor or cadaver.

Accepted Answer

Autologous hematopoietic stem cell transplant is a treatment for leukemias and lymphomas that involves replacing a patient's stem cells after harvesting and treating them with chemotherapy or radiation therapy.The patient also undergoes chemotherapy or radiation therapy to ablate the bone marrow, and then previously harvested stem cells are reinfused to replace the bone marrow.When the stem cells come from a sibling or parent, unrelated donor, or cadaver, the transplant is called syngeneic.If the stem cells come from a twin, the transplant is allogenic.

Question 11

For _____ cancer, epidemiologic studies indicated that alcohol consumption increases the risk of development.&#10;A)ovarian&#10;B)prostate&#10;C)mouth&#10;D)pancreatic
