Previous studies have shown cognitive impairment in breast cancer survivors who were exposed to adjuvant chemotherapy. Neural damage by chemotherapy might have played some part in these findings. The current study explored the regional brain volume difference between breast cancer survivors exposed to adjuvant chemotherapy (C+) and those unexposed (C−).

PURPOSE Few studies have been conducted to elucidate the psychological distress of terminally ill cancer patients. This study attempted to determine the prevalence of adjustment disorders (AD), major depression (MD), and post-traumatic stress disorder (PTSD) among terminally ill cancer patients, to identify factors that contribute to them, and to determine how they change longitudinally. PATIENTS AND METHODS Consecutive terminally ill cancer patients were recruited. Patients were assessed for psychiatric disorders by structured clinical interview twice: once at the time of their registration with a palliative care unit (baseline), and again at the time of their palliative care unit admission (follow-up). Possible contributed biomedical and psychosocial factors were evaluated. RESULTS The proportions of patients diagnosed with AD, MD, and PTSD at baseline (n = 209) were 16.3%, 6.7%, and 0% respectively, whereas at follow-up (n = 85), 10.6% were diagnosed with AD and 11.8% with MD. Lower performance status, concern about being a burden to others, and lower satisfaction with social support were significantly associated with AD/MD at baseline. There were changes in the diagnosis of AD and MD in 30.6% of the patients. Only the Hospital Anxiety and Depression Scale at the baseline was significantly predictive of AD/MD at follow-up. CONCLUSION The factors underlying psychological distress are multifactorial. Early intervention to treat subclinical anxiety and depression may prevent subsequent psychological distress.

We herein describe the development and validation of the Cancer Fatigue Scale (CFS) for assessment of fatigue in cancer patients. We designed this scale specifically to reflect the nature of fatigue experienced by cancer patients, by using factor analysis; the CFS is a 15-item scale composed of 3 subscales (physical, affective, and cognitive subscales). Three hundred seven cancer patients participated in the validation phase. Construct validity, confirmed by repeating factor analysis, was good. Convergent validity, confirmed by a correlation between CFS and a visual analogue scale for fatigue, was also shown to be good (r = 0.67, P < 0.001). The CFS had good stability (average test-retest reliability r = 0.69, P < 0.001) and good internal consistency (Cronbachs alpha coefficient for all 15 items = 0.88). The present study indicates that the CFS is a brief, valid, and feasible measure of fatigue for use with cancer patients.

Abstract Fatigue is one of the most frequent symptoms in cancer patients. However, the precise causes of this fatigue are still unknown, and this situation makes it difficult to combat the problem. The present study was conducted to investigate factors correlated with fatigue in disease-free breast cancer patients. A group of 134 randomly selected ambulatory breast cancer patients who had undergone successful surgical treatment participated. They completed the Cancer Fatigue Scale, the Hospital Anxiety and Depression Scale, the Mental Adjustment to Cancer Scale, and an ad hoc questionnaire detailing physical symptoms, social support, and demographic variables at home and returned them by mail the following day. Multiple regression analysis revealed that fatigue was significantly correlated with dyspnea, insufficient sleep, and depression, and that these three variables accounted for a total of 46% of variance in fatigue. Factors concerned with the cancer and treatment, such as disease stage, lymph node metastasis, number of days since operation, past intravenous chemotherapy, radiotherapy, current use of fluoropyrimidine compounds, and current use of tamoxifen citrate were not correlated with fatigue. The results suggest that fatigue in this population is determined by current physical and psychological distress rather than by the cancer itself and prior cancer treatments, and that the management of dyspnea, insomnia, and depression might be important in reducing fatigue in this population.

Adjustment disorders and major depression are common psychiatric disorders in patients with cancer and have a serious impact on quality of life. The problem in clinical oncology settings is underrecognition of these disorders; as a result, screening is recommended to detect them. The goal of the current study was to develop a new, brief screening tool for adjustment disorders and major depression and to compare its performance with that of existing screening methods.

Although it has been indicated that patients with lung cancer experience higher level of fatigue than patients with other cancers, few published studies have focused on the characteristics of this fatigue and how it interferes with daily activities. The purpose of this study was to clarify fatigue prevalence and the factors correlated with fatigue, and to develop a screening method for fatigue in patients with advanced lung cancer. One hundred fifty-seven patients completed two fatigue scales (Cancer Fatigue Scale [CFS], and Fatigue Numerical Scale [FNS]) plus other measures, along with a self-administered questionnaire asking whether fatigue had interfered with any of 7 areas of daily activities. Fifty-nine percent of patients had experienced clinical fatigue, which was defined as fatigue that interfered with any daily activities. Logistic regression analysis demonstrated that symptoms of dyspnea on walking, appetite loss, and depression were significant correlated factors. Both CFS and FNS were found to have sufficient sensitivity and specificity for use as a screening tool. The results indicated that fatigue is a frequent and important symptom, which is associated with both physical and psychological distress in this population. The CFS and FNS were confirmed to have sufficient screening ability.

PURPOSE There have been few psychosocial studies of patients after curative resection of non-small-cell lung cancer (NSCLC). The purpose of this study was to clarify the clinical course of depression and psychological distress of such patients during the year after surgery and to identify predictors of their long-term outcome. PATIENTS AND METHODS A total of 212 patients completed assessments during a 12-month follow-up period after curative resection of NSCLC. Psychological measurements at 1, 3, and 12 months after surgery were conducted using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (ed 3), Revised, and the Profiles of Mood States (POMS) scale. Univariate and multivariate analyses were used to identify predictors of psychological outcome according to these two methods of assessment. RESULTS The prevalence of depression did not change during the year after curative resection (range, 4.7% to 8.0%). The total POMS score was also unaltered during the year after surgery: the anger-hostility (P <.001) and tension-anxiety subscale scores (P <.026) had increased at 12 months, but the vigor-activity subscale score had also increased (P <.001). All predictors of psychological outcome at 12 months included a depression episode after the diagnosis of lung cancer or at 1 month after surgery. Less-educated status was also a significant predictor of depression at 12 months. CONCLUSION These results suggest the need for psychosocial support even after curative resection of NSCLC and indicate that an approach that includes repetitive perioperative assessment of depression and careful attention to less-educated patients might be of benefit to patients in ameliorating depression and psychological distress during the year after curative resection.

AbstractObjectives: To investigate the prevalence of, and risk factors for psychological distress following first recurrences of breast cancer. Patients and methods: The sample was drawn consecutively from the inpatient and outpatient populations of the National Cancer Center Hospital in Japan during an 18-month period from July 1996 to December 1997. Of the 56 eligible patients, 55 women aged 30–73 year with recurrent breast cancer participated in the study. The prevalence of psychological distress, including major depressive disorder and adjustment disorders was evaluated according to the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Third edition-revised (DSM-III-R). Risk factors for psychological distress were analyzed with a logistic regression model. Results: Of the 55 subjects, 42 met the DSM-III-R criteria for major depressive disorder or adjustment disorders. Major depressive disorder was seen in 4 (7%), and adjustment disorders in 19 (35%). Logistic regression analysis showed that a disease-free interval of less than 24 months significantly predicted a diagnosis of major depressive disorder or adjustment disorders (odds ratio 5.28, 95% confidence interval; 1.28–21.8, p=0.02). Conclusions: These results suggest that it is important for all oncology staff to pay careful attention to the psychological health of patients who have been informed of their cancer recurrence, and that some psychosocial intervention is necessary for preventing distress in patients facing early recurrence.

Fatigue has been recognized as one of the most distressing symptoms in cancer patients. Concise assessment is essential to managing this symptom. To that end, the Brief Fatigue Inventory (BFI), a 9-item questionnaire, was designed to assess fatigue in cancer patients. The purpose of this study was to examine the validity and reliability of the Japanese version of this scale (BFI-J), when compared with previously validated fatigue instruments. We randomly selected 252 cancer patients and presented them with the BFI-J, along with the Cancer Fatigue Scale; Profile of Mood States fatigue, vigor, and depression subscales; and European Organization for Research and Treatment of Cancer QLQ-C30. Specifically, the reliability and construct, criterion, convergent, and discriminant validity of each instrument were evaluated. Additionally, fatigue severity classification was explored using the BFI-J. The results indicated that the BFI-J is a brief, valid, and feasible measure of fatigue for use with Japanese cancer patients.

This study aimed to compare the impact of dyspnea, pain, and fatigue on daily life activities in ambulatory patients with advanced lung cancer. One hundred seventy-one outpatients with advanced lung cancer completed a questionnaire about symptom severity and whether symptoms interfered with daily life activities (normal work, walking, sleep, mood, relation with other people, enjoyment of life, and general activities). The results indicated that 1) dyspnea and fatigue interfered with at least one daily life activity in more than half the patients, and pain in about 40%, 2) dyspnea and fatigue interfered predominantly with physical activities, such as walking and work, whereas pain interfered with all activities almost equally, and 3) symptoms rated as low severity (1 to 3 on a 0-10-point numerical scale) were severe enough to interfere with at least one daily life activity. To recognize the impact of symptoms may contribute to provide better management.
