Common psychiatric disorders in cancer patients. I. Adjustment disorders and depressive disorders

The characteristics and risk factors for common psychiatric disorders in patients with cancer seeking help for mental health

BACKGROUND

Although the adverse effects of cancer diagnoses and treatments on mental health are known, about less than 10% of patients are estimated to be referred to seek help. The primary purpose of this study was to obtain the baseline information on patients with cancer seeking help for mental health who presented for the first time to the psycho-oncology outpatient clinic, and to identify risk factors that may provide clues healthcare practitioners in recognizing those needing psychological help in oncology practice.

METHODS

We reviewed the charts of 566 patients with cancer who were referred to the psycho-oncology outpatient clinic over a two-year period. The study includes the socio-demographic data, illness characteristics, psychiatric characteristics, psychiatric diagnoses, and treatment recommendations for these patients.

RESULTS

The incidence of diagnoses of psychiatric disorders was 97.5%. The distributions of psychiatric diagnoses were as follows: any kind of adjustment disorders, mood disorders, anxiety disorders, organic brain syndrome, personality disorders, delusional disorder, and insomnia. Recurrence of cancer, other chronic medical illnesses, a history of psychiatric disorders, poor social support, and low income comprised the common significant risk factors for adjustment disorders, mood disorders, and anxiety disorders. These risk factors were also seen to be significant in the regression analysis in terms of sex.

CONCLUSION

This study identifies the distribution of psychiatric disorders, the risk factors for specific psychiatric disorders, and draws attention to the fact that there are serious delays in patients seeking psychiatric help and in the referrals of oncologists for psychological assessment. Identifying risk factors and raising oncologists' awareness toward risk factors could help more patients gain access to mental health care much earlier.

Psychotherapy in the Oncology Setting

A person who faces the diagnosis of cancer is subjected to changes within his body, but also with regard to his view of himself and his social relationships. Cancer related psychological distress occurs frequently and has a different prevalence according to-among other factors-cancer type and stage of disease. The main psychiatric disturbances observed in patients with cancer are adjustment disorders and affective disorders (anxiety and depression), which in the majority of patients are due to stressors related to the occurrence and threat of the disease and pre-existing psychological vulnerabilities; however, they might also be a direct consequence of biological causes either resulting from bodily modifications induced by the cancer or from treatment side effects. This chapter provides theoretical and practical information on the main psychotherapeutic approaches for cancer patients, complemented by some reflections on their clinical and scientific evidence.

A case report of brief psychotic disorder with catalepsy associated with sequential life-threatening events in a patient with advanced cancer

Background

Cancer is commonly perceived as life-threatening and universally stressful; however, brief psychotic disorder, which occurs in response to extremely stressful events, has not been reported.

Case presentation

A 63-year-old woman, who was diagnosed as having pancreatic cancer with liver metastasis, became unresponsive with very little reaction to verbal contact after sequential life-threatening events, such as thrombosis of both pulmonary arteries and stenosis of the third portion of the duodenum, due to disease progression over 3 weeks beginning with oncological emergency hospital admission. Laboratory findings and electroencephalography were unremarkable. She maintained the position when the psycho-oncologist raised her hand (catalepsy). She had no medical history of psychiatric illness, or alcohol or drug abuse. From these findings, she was suspected of having a brief psychotic disorder with catalepsy and substupor, and 2.5 mg of haloperidol was administered. Her psychiatric symptoms disappeared in 4 days and the diagnosis of brief psychotic disorder was confirmed.

Conclusions

Brief psychotic disorders can manifest in patients with cancer. Careful clinical assessment is needed to correctly diagnose patients with cancer who develop brief psychotic disorders and to identify those who will benefit from correct treatment.

Psychodynamic interventions in cancer care I: psychometric results of a randomized controlled trial

OBJECTIVE

This study aimed to assess the effectiveness of psychodynamic interventions in cancer care.

METHODS

Between 2006 and 2009, each consecutive outpatient of the Oncology Center of the University Hospital of Lausanne was invited to participate in a trial evaluating the effects of psychological support. Accepting patients were randomly assigned to an immediate intervention or a delayed intervention [4-month waiting list]. Patients who declined support were asked to participate in an observational group [OG]. Socio-demographic and medical data, anxiety, and depression [HADS], psychological distress [SCL-90], alexithymia [TAS] and quality of life [EORTC] were recorded at baseline, and at 1, 4, 8, and 12-months follow-up.

RESULTS

Of the 1973 approached patients, 1057 were excluded, 530 refused, and 386 were included with 196 of them participating in the OG. Of the patients in the intervention group [IG] [N = 190], 94 were randomized to the immediate intervention and 96 to the delayed intervention group (dIG). IG patients were younger, predominantly female, and had more psychological symptoms compared with those in the OG. Although patients of the IG and OG showed significant improvement in quality of life from baseline to 12-months follow-up, other outcomes [anxiety, depression, psychological distress, and alexithymia] remained unchanged.

CONCLUSIONS

The intervention was not effective with regards to psychometric outcome. The results have to be interpreted in light of the study design [untargeted intervention], the low levels of psychiatric symptoms, dropout of symptomatic patients, and the high prevalence of alexithymia.

Informing about diagnosis, relapse and progression of disease--communication with the terminally III cancer patient

This chapter focuses on four crucial situations representing important challenges for physician-patient communication: diagnosis, relapse, progression of disease and terminal illness. The psychological aspects of each situation are discussed and a framework for communication is provided. The aim of the chapter is to invite the oncology clinician to think about these different stages of disease and to support him or her in the communication with the patient. Communication with cancer patients is a difficult task in clinical practice and it is especially challenging when informing about diagnosis and prognosis, when relapse occurs or when the disease is progressing. Physician-patient communication has undergone considerable changes and has become-compared to decades before, when medicine was based on a more paternalistic model of care--a central duty and challenge of the oncology clinician. The following chapter aims to discuss key elements of communication in the above-mentioned specific situations; it is based on our clinical experience as psycho-oncologists and teachers of communication skills training (Razavi and Stiefel 1994; Stiefel and Razavi 1994; Razavi et al. 2003; Berney and Stiefel 2004; Delvaux et al. 2005; Voelter et al. 2005; Bragard et al. 2006).

Distress and coping in cancer patients: feasibility of the Icelandic version of BSI 18 and the WOC-CA questionnaires

The aim of this study was to test the feasibility of two instruments within an Icelandic context, the Brief Symptom Inventory 18 (BSI 18) and the Ways of Coping Inventory--Cancer Version (WOC-CA) with specific focus on gender and type of treatment and coping techniques among cancer patients during time of treatment. The sample consisted of 40 cancer patients in three oncology outpatient clinics in Iceland, 53% were women and 47% men. The majority of the participants belonged to the age group 51-70. Cronbach alpha, means, confidence intervals and standard deviations were used for analysis as well as Mann-Whitney U-test for testing differences between genders in relation to psychological distress and coping. Anxiety was the factor causing the greatest distress, mainly reported by patients receiving chemotherapy. More women experienced depression than men, women (18.4%), men (8.3%). Distancing was the most frequently reported coping strategy, and men seemed to focus on the positive side more often than women did (P < 0.01). Although the results should be approached with caution, as the sample size was small, they do provide support for the strength of the measurements. Also the findings indicate that gender differences should be taken into account.

Levels of omega-3 fatty acid in serum phospholipids and depression in patients with lung cancer

Previous studies suggested that omega-3 fatty acids (FAs) have therapeutic effects against depression, but there is no evidence in the oncological setting. Our preliminary study reported the association between lower omega-3 FA intake and occurrence of depression in lung cancer patients. To explore the association further, the present study examined whether depression was associated with lower levels of omega-3 FAs in serum phospholipids. A total of 717 subjects in the Lung Cancer Database Project were divided into three groups by two cutoff points of the Hospital Anxiety and Depression Scale depression subscale (HADS-D). In all, 81 subjects of the nondepression and minor depression groups (HADS-D<5 and 5⩽HADS-D⩽10, respectively) were selected to match with 81 subjects of the major depression group (HADS-D>10) for age, gender, clinical stage, and performance status. Fatty acids were assayed by gas chromatography and compared among the three matched groups. There were no differences between the major depression group and nondepression group in any FAs. The minor depression group had higher mean levels of docosahexaenoic acid (mean±s.d. (%), nondepression: 7.40±1.54; minor depression: 7.90±1.40; major depression: 7.25±1.52, P=0.017). These results suggested that serum FAs are associated with minor, but not major, depression in lung cancer patients.

The Hospital Anxiety and Depression Scale in Greek cancer patients: psychometric analyses and applicability

GOALS OF WORK

The aim of the present study was to validate the Greek version of the Hospital Anxiety and Depression Scale (HAD) in a palliative care unit.

PATIENTS AND METHODS

The scale was translated with the "forward-backward" procedure to Greek. It was administered twice, with a 1-week interval, to 120 patients with advanced cancer. Together with the HAD scale, the patients also completed the Spielberger State-Anxiety Scale (STAI-S).

MAIN RESULTS

Factor analyses identified a two-factor solution corresponding to the original two subscales of the HAD, which were found to be correlated. The Greek version of the HAD had Cronbach's alphas for the anxiety and depression scales of 0.887 and 0.703, respectively. Validity as performed using known-group analysis showed good results. Both anxiety and depression subscales discriminated well between subgroups of patients differing in disease severity as defined by ECOG performance status. Correlations between the HAD scale and the STAI-S was 0.681 for the anxiety subscale and 0.485 for the depression subscale.

CONCLUSIONS

These psychometric properties of the Greek version of the HAD scale confirm it as a valid and reliable measure when administered to patients with advanced cancer.

A prospective study to compare three depression screening tools in patients who are terminally ill

Depression is a significant symptom for approximately one in four palliative care patients. This study investigates the performance of three screening tools. Patients were asked to verbally rate their mood on a scale of 0-10; to respond "yes" or "no" to the question "Are you depressed?," and to complete the Edinburgh depression scale. They were also interviewed using a semi-structured clinical interview according to DSM-IV criteria. Complete data was available for 74 patients. For the single question, a "yes" answer had a sensitivity of 55% and specificity 74%. The Edinburgh depression scale at a cut-off point of > or =13 had a sensitivity of 70% and specificity of 80%. The verbal mood item with a cut-off point of > or =3 had a sensitivity of 80% and specificity of 43%. The Edinburgh depression scale proved to be the most reliable instrument for detecting clinical depression in palliative care patients.

How do palliative medicine physicians assess and manage depression

Depression is a significant symptom for approximately 25% of palliative care patients, but is frequently unrecognized and untreated. This study was carried out to determine how senior doctors working in palliative medicine in the UK assessed and managed depression in their patients. A questionnaire was sent to all palliative care units with a designated consultant or medical director. Questions were asked about assessment and management of depression (pharmacological and nonpharmacological); difficulties encountered, qualifications and current post. The response rate was 63%; two-thirds (90) of respondents were consultants and a further 21 medical directors. The majority (73%) routinely assessed for depression with 27% using the Hospital Anxiety and Depression (HAD) Scale and 10% asking the patient 'are you depressed'? The most frequently prescribed medication was SSRI (80%). Less than 6% prescribed psychostimulants. Respondents reported difficulties with the assessment and management of depression which mainly focused on distinguishing symptoms of depression from sadness and whether it was appropriate to treat patients when life expectancy was short. Difficulties were identified in accessing psychiatric input by 47%. Depression is identified as being a difficult symptom to manage by many senior palliative care physicians in the UK and suggestions are made as to how some of theses issues can be addressed.

A survey of antidepressant prescribing in the terminally ill

Depression is a symptom in a quarter of patients admitted to a palliative care unit, but little is known of how depression in terminally ill patients is treated. We reviewed 1046 consecutive patient admissions, of whom 106 (10%) were prescribed antidepressant medication while under the care of a palliative care team. Of these patients, 21 were prescribed antidepressants when under the care of the home care team, but 80 patients (76%) were started on medication during the final 2 weeks of life. There was consequently insufficient time for the medication to have any therapeutic effect. Seventeen patients were discharged home on antidepressant medication. Three patients were referred for a psychiatric assessment. Patients prescribed antidepressants were significantly younger (P = 0.002) than those who were not. There were no prescriptions for psychostimulants. Although the numbers of patients prescribed antidepressant medication were low in all disease groups, it was notable that patients with breast cancer were prescribed antidepressant medication more frequently than any other patient group. We conclude that there appears to be a need for a coordinated approach to both the assessment and the treatment of depression in terminally ill patients.

Cancer in married couples: higher or lower distress?

This study focuses on the question of what occurs when both spouses become seriously ill. Our hypothesis was that psychological distress in married couples involving two ill partners is far higher than when only one partner is ill. The study group comprised 20 married couples, in which both spouses were diagnosed with cancer. Two comparison groups were also studied: 20 married couples with the husband diagnosed with cancer, and 20 couples with the wife diagnosed with cancer. All patients in the three groups completed four self-report scales: the Brief Symptom Inventory (BSI); the Perceived Family Support (PFS); the Impact of Events Scale (IES); and the Mental Adjustment to Cancer (MAC). The healthy spouses completed only the first three scales. Our findings supported the null hypothesis--that is, that the psychological distress in married couples with both partners diagnosed with cancer was not significantly different than when only one partner had cancer. Our findings also showed that neither sociodemographic background, medical condition, nor family support affect patient distress. Gender differences were found with Intrusiveness contributing to the distress of male, but not female, patients. This study confirms and augments earlier work, and shows that partners of cancer patients report a high degree of distress, with this level of distress not being much different from that of the patients.

Psychological sequelae of cancer diagnosis: a meta-analytical review of 58 studies after 1980

OBJECTIVE

In a review of the literature from 1980 to 1994 on psychological and psychiatric problems in patients with cancer, the prevalence, severity, and the course of these problems (i.e., depression, anxiety, and general psychological distress) were studied with the help of meta-analyses and qualitative analyses. Apart from this, qualitative analyses were also applied with respect to other relevant variables.

METHOD

A literature search in MEDLINE was conducted and cross-references of articles identified via MEDLINE. Meta-analysis was applied when possible.

RESULTS

There seemed to be a wide variation across studies in psychological and psychiatric problems. Meta-analysis showed no significant differences between cancer patients and the normal population with respect to anxiety and psychological distress. However, cancer patients seemed to be significantly more depressed than normals. Compared with psychiatric patients, cancer patients were significantly less depressed, anxious, or distressed. Compared with a sample of other medical patients, cancer patients showed significantly less anxiety. With respect to course, a significant decrease was found in the meta-analysis for anxiety, but not for depression. Further meta-analyses showed significant differences among groups of cancer patients with regard to tumor site, sex, age, design of the study, and year of publication. From the qualitative analyses, it seemed that medical, sociodemographic, and psychological variables were related inconsistently to psychological and psychiatric problems.

CONCLUSION

With the exception of depression, the amount of psychological and psychiatric problems in patients with cancer does not differ from the normal population. The amount of psychological and psychiatric problems is significantly less in cancer patients than in psychiatric patients. The amount of anxiety is significantly less in cancer patients than in other groups of medical patients with mixed diagnoses, whereas depression is not. Future studies should aim at exploring possible causes for the sometimes impressive differences in psychological or psychiatric problems among patients with cancer.

Coping with additional stresses: comparative study of healthy and cancer patient new immigrants

The adjustment and psychological distress of 166 cancer patients, who are new immigrants from the former Soviet Union, was assessed and compared to that of 288 healthy new immigrants from the the former Soviet Union. The healthy new immigrants had many adjustment problems and their psychological distress was fairly high. The cancer patients reported extremely severe psychological distress. In the healthy immigrants, age contributed to distress while family support had significant protective effects especially in the male immigrants. In the patients, these differences were even more extreme with family support being protective in the male group but not in the female group. Intrusiveness (IES) seems to be maladaptive adding to distress. The results clearly indicate that additional stresses, such as immigration, make cancer patients more vulnerable. The results also suggest possible interventions, especially those that will help to decrease intrusiveness.
