Anemia
Lower than normal red blood cell count; a possible side effect of chemotherapy.
Antiemetics

Biopsy
The removal and examination of tissue from the living body, performed to establish precise diagnosis.
Cancer
Diseases characterized by abnormal and uncontrolled cell division. Cancer cells can attack tissues in the body and possibly spread to other parts of the body. There are many different kinds of cancer.
Carcinoembryonic antigen (CEA)
A substance normally found in fetal tissue. If found in an adult, it may suggest that a cancer, especially one starting in the digestive system, may be present. Tests for this substance may help in finding out if colorectal cancer has come back after treatment. The test is not helpful for screening for colorectal cancer because of the large number of false positives and false negatives.
Carcinoma in situ
Describes a condition in the earliest stage, also known as precancerous, or stage 0.
Catheter

Colorectal cancer
Cancer of the colon and/or rectum.
Colostomy
An opening in the abdomen used to rid the body of waste; sometimes needed after surgery for cancer of the rectum (usually temporarily).
Combination chemotherapy
Treatment consisting of the use of two or more chemicals to achieve maximum kill of tumor cells.
Comorbidity
The condition of having two or more diseases at the same time. Generally used with cancer patients to refer to conditions not related to the cancer.
CT scan
A computer-assisted X-ray technique. A CT scan can show where metastases are and help an oncologist, surgeon, and radiologist decide together how best to treat cancer.
Cytotoxic
Pertaining to or exhibiting cytotoxicity.
Cytotoxicity
The degree to which an agent possesses a specific destructive action on certain cells.
Dehydrated
Condition that occurs when the body loses too much water. Dehydration can be caused by severe diarrhea or vomiting.
Digestive system
The organs (salivary glands, mouth, esophagus, stomach, liver, pancreas, gallbladder, small and large intestines, and rectum) that turn food into energy for the body and allow waste products to leave the body through bowel movements.

The time following treatment in which no cancer is detected in the body.
Digital rectal exam (DRE)
A test in which a doctor or nurse uses a gloved finger to feel the lower part of the rectum for abnormal areas.
Diverticulosis or Diverticulitis
A condition that occurs in organs like the stomach or colon when small pouches or sacs (diverticula) in the organ walls become inflamed. Diverticulitis may be a risk factor of certain cancers.
Double-contrast barium enema (DCBE)
A DCBE is a series of X-rays of the colon and rectum. The patient is given an enema with a barium solution, and air is pumped into the rectum. The barium and air outline the colon and rectum on the X-rays. Polyps may show up on the X-rays.
Dysarthria
Speech that is characteristically slurred, slow, and difficult to produce. Patients with dysarthria may also have problems controlling the pitch, loudness, rhythm, and voice qualities of their speech.
Dysesthesia
Condition that distorts the senses – usually touch. Normal stimuli, such as a light touch, may feel unpleasant or painful to someone with dysesthesia.
Endorectal ultrasound (EUS)
A procedure in which an endoscope (a thin, lighted tube) is inserted into the body and used to bounce high-energy sound waves (ultrasound) off internal organs to make a picture (sonogram). Also called endosonography.
Fecal occult blood test (FOBT)
A test used to screen for colorectal cancer, in which a stool sample is examined for blood.
First-line therapy
In patients with cancer, it can be surgery, chemotherapy, radiation therapy, or a combination of these therapies.
Flexible sigmoidoscopy
A test to screen for cancer, in which a lighted tube is placed in the rectum so the doctor can look inside.
Gastrointestinal or digestive system
Pertaining to or communicating with the stomach or intestine.
Hand-foot syndrome
A condition marked by pain, swelling, numbness, tingling, or redness of the hands or feet. It sometimes occurs as a side effect of certain anticancer drugs.
Immunotherapy
A general term encompassing active and passive immunization. Treatment with immunopotentiators and immunosuppressants.
Inflammatory bowel disease (IBD)
A general term to describe conditions that cause the colon and rectum to become inflamed. Conditions within IBD include Crohn’s disease and ulcerative colitis.
Infusion
A method of putting fluids, including drugs, into the bloodstream.
Irritable bowel syndrome (IBS)
A colon disorder involving diarrhea, constipation, diarrhea alternating with constipation, abdominal bloating, abdominal pain or discomfort, and passing mucus in the stool.
K-ras test
A test done on a tissue sample from a tumor in a lab. It can tell whether or not the tumor is likely to respond to certain biologic therapies.
Leukopenia
Lower than normal white blood cell count; a possible side effect of chemotherapy.
Liver metastases
The spread of cancerous tumors from a distant organ to the liver.
Liver resection
Surgery to remove a diseased or cancerous portion of the liver. In some mCRC patients, a liver surgeon can remove metastases, improving the patient’s prospects.
Local therapy
A treatment that affects cancer cells and the area close to the tumor.
Lymph nodes
Small bean-shaped collections of immune system cells that help fight infections and also have a role in fighting cancer. Also called lymph glands. Cancers of the colon and rectum may spread to regional (nearby) lymph nodes.

When cancer has spread from one body part to another.
Neoadjuvant therapy
Treatment given before primary treatment, such as chemotherapy before surgery.
Neuropathy
Nerve condition that affects nerve function (parts of the nervous system besides the brain and spinal cord). Neuropathy causes pain, tingling, numbness, swelling and muscle weakness. Injury, infection, toxic substances, drugs (such as anticancer drugs), or diseases (such as cancer, diabetes, kidney failure or malnutrition) can cause neuropathy.
Neurotoxicity
The tendency of some treatments to cause damage to the nervous system.
Neutropenia
An abnormally low number of a particular type of white blood cell, which can sometimes be a side effect of chemotherapy. Neutropenia increases a patient’s susceptibility to infection.
Palliative care
Also called supportive care or symptom management, treatment not to cure cancer but instead to improve the quality of life of patients who have serious or life-threatening diseases.
