Psycho- Oncology has focused on two aspects
of cancer;the psychosocial impacts of cancer on the quality of life (QOL)of
the patient, family and staff, and the role that psychosocial and behavioral
factors may have in cancer risk and survival.(264)
Established in September 1995, the Psycho- Oncology Division has focused
on the psychosocial impacts of cancer on the QOL of the patient.
Psychiatric Epidemiology in Cancer Patients Psychiatric prevalence studies in Western countries have revealed that
approximately half of patients with all stages of cancer showed distress,
with depression being the most common manifestation.
Why depression?The frequently observed depression in cancer patients seems
to be related with truth- telling practice in cancer
care (e.g. disclosure of the diagnosis, recurrence, termination of the
curative treatments, and genetic high- risk). Since a few studies demonstrated
the extensive range of psychiatric disorders in patients with different
clinical courses of cancer, patients with early, advanced and recurrent
cancer are now systematically assessed using the Semi- structured
Clinical Interview for the Diagnostic and Statistical Manual of Mental
Disorders (SCID). The preliminary investigation using the Mental
Adjustment to Cancer scale and the Profile of Mood States has demonstrated
that depression was common and was significantly associated with advanced
disease, being unmarried and helpless/hopeless coping
in 99 ambulatory head and neck cancer patients.(265)
Screening for Psychiatric Disorders in Cancer PatientsNicotine and alcohol dependence (267) are the refractory substance dependence disorders, and the former is considered to be a predictor of the success or failure at stopping smoking. To identify smoking- related cancer patients who will have difficulty stopping smoking, a Japanese version of the Fagerstrom test for nicotine dependence (FTND)was developed and compiled while the cancer patients were being simultaneously assessed using SCID. One hundred and fifty- one lung and head and neck cancer patients participated in this study. The results showed that an optimal cut- off point for screening for nicotine dependence was 5/6.(268) These results suggested that the Japanese version of the FTND is a reliable and valid measure of nicotine dependence in patients with smoking- related cancers. Pharmacological Intervention for Depression and Other Symptoms Although the use of antidepressants is thought to
be beneficial for cancer patients,(269)
it is often not possible to use the psychotropics due to adverse effects
of oversedation, gastrointestinal obstruction and their nature of slow
effects. Furthermore, there are no universally accepted guidelines for
usage of antidepressants in cancer patients. An algorithm
for the psychopharmacological treatment of depression in advanced cancer
patients has been developed.(270-
272) Psychosocial and Behavioral Intervention for Distress and Coping The need for a large variety of
psychosocial interventions has increased
along with rising numbers of cancer patients
surviving for longer periods. The primary
goals of psychosocial interventions designed
for cancer patients are improved QOL;to
decrease the feeling of alienation by talking
with other cancer patients in a similar
situation, to lessen the feelings of isolation,
helpless/hopeless coping, to reduce fear
and anxiety regarding treatments and to
assist in clarifying misperceptions and
misinformation. It is not clear whether there
is a weak link between psychosocial and
behavioral factors and the subsequent
development of cancer. However, the second
goal is expected to exert beneficial effects on
survival presumably by enhancing effective
cancer coping skills and reducing
psychological distress as well as improving
lifestyle and compliance with medical
regimens. |
