Assessment

It is important that cancer patients undergo a careful assessment for posttraumatic stress disorder (PTSD) so that early symptoms may be identified and treated. The timing of this assessment will vary with the individual patient. Cancer is an experience of repeated traumas and undetermined length. The patient may experience stress symptoms anytime from diagnosis through completion of treatment and cancer recurrence. In patients who have a history of victimization (such as Holocaust survivors) and who have PTSD or its symptoms from these experiences, symptoms can be started again by certain triggers experienced during their cancer treatment (for example, clinical procedures such as being inside MRI or CT scanners). While these patients may have problems adjusting to cancer and cancer treatment, their PTSD symptoms may vary, depending on other factors. The symptoms may become more or less prevalent during and after the cancer treatment.

Symptoms of PTSD usually begin within the first 3 months after the trauma, but sometimes they do not appear for months or even years afterwards. Therefore, cancer survivors and their families should be involved in long-term monitoring.

Some people who have experienced an upsetting event may show early symptoms without meeting the full diagnosis of PTSD. However, these early symptoms predict that PTSD may develop later. Early symptoms also indicate the need for repeated and long-term follow-up of cancer survivors and their families.

Diagnosing PTSD can be difficult since many of the symptoms are similar to other psychiatric problems. For example, irritability, poor concentration, increased defensiveness, excessive fear, and disturbed sleep are symptoms of both PTSD and anxiety disorder. Other symptoms are common to PTSD, phobias, and panic disorder. Some symptoms, such as loss of interest, a sense of having no future, avoidance of other people, and sleep problems may indicate the patient has PTSD or depression. Even without PTSD or other problems, normal reactions to the cancer diagnosis and treatment of a life-threatening disease can include interfering thoughts, separating from people and the world, sleep problems, and over-excitability.

Questionnaires and interviews are used by health care providers to assess if the patient has symptoms of stress and to determine the diagnosis.

Other problems may also exist in addition to PTSD. These problems can include substance abuse, emotional problems, and other anxiety disorders, including major depression, alcohol dependence, drug dependence, social fears, and/or obsessive-compulsive disorder.



Glossary Terms

anxiety (ang-ZY-uh-tee)
Feelings of fear, dread, and uneasiness that may occur as a reaction to stress. A person with anxiety may sweat, feel restless and tense, and have a rapid heart beat. Extreme anxiety that happens often over time may be a sign of an anxiety disorder.
assessment (uh-SESS-ment)
In healthcare, a process used to learn about a patient’s condition. This may include a complete medical history, medical tests, a physical exam, a test of learning skills, tests to find out if the patient is able to carry out the tasks of daily living, a mental health evaluation, and a review of social support and community resources available to the patient.
cancer (KAN-ser)
A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissues and can spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.
clinical
Having to do with the examination and treatment of patients.
CT scan
Computed tomography scan. A series of detailed pictures of areas inside the body taken from different angles; the pictures are created by a computer linked to an x-ray machine. Also called computed tomography scan, computerized tomography, computerized axial tomography scan, and CAT scan.
depression (dee-PREH-shun)
A mental condition marked by ongoing feelings of sadness, despair, loss of energy, and difficulty dealing with normal daily life. Other symptoms of depression include feelings of worthlessness and hopelessness, loss of pleasure in activities, changes in eating or sleeping habits, and thoughts of death or suicide. Depression can affect anyone, and can be successfully treated. Depression affects 15-25% of cancer patients.
diagnosis (DY-ug-NOH-sis)
The process of identifying a disease, such as cancer, from its signs and symptoms.
disorder (dis-OR-der)
In medicine, a disturbance of normal functioning of the mind or body. Disorders may be caused by genetic factors, disease, or trauma.
drug
Any substance, other than food, that is used to prevent, diagnose, treat or relieve symptoms of a disease or abnormal condition. Also refers to a substance that alters mood or body function, or that can be habit-forming or addictive, especially a narcotic.
follow-up
Monitoring a person's health over time after treatment. This includes keeping track of the health of people who participate in a clinical study or clinical trial for a period of time, both during the study and after the study ends.
MRI
A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. MRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. MRI is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called magnetic resonance imaging, nuclear magnetic resonance imaging, and NMRI.
post-traumatic stress disorder (POST-traw-MA-tik stres dis-OR-der)
An anxiety disorder that develops in reaction to physical injury or severe mental or emotional distress, such as military combat, violent assault, natural disaster, or other life-threatening events. Having cancer may also lead to post-traumatic stress disorder. Symptoms interfere with day-to-day living and include reliving the event in nightmares or flashbacks; avoiding people, places, and things connected to the event; feeling alone and losing interest in daily activities; and having trouble concentrating and sleeping. Also called PTSD.
recurrence (ree-KER-ents)
Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body. Also called recurrent cancer.
symptom
An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.
