Effect of the cognitive hierarchy in the systematic desensitization treatment of anticipatory nausea in cancer patients: A component comparison with relaxation only, counseling, and no treatment

Prevention and treatment of anticipatory chemotherapy-induced nausea and vomiting in pediatric cancer patients and hematopoietic stem cell recipients: Clinical practice guideline update

This 2021 clinical practice guideline update provides recommendations for preventing anticipatory chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. Recommendations are based on systematic reviews that identified (1) if a history of acute or delayed CINV is a risk factor for anticipatory CINV, and (2) interventions for anticipatory CINV prevention and treatment. A strong recommendation to optimize acute and delayed CINV control in order to prevent anticipatory CINV is made. Conditional recommendations are made for hypnosis, systematic desensitization, relaxation techniques, and lorazepam for the secondary prevention of anticipatory CINV. No recommendation for the treatment of anticipatory CINV can be made.

Supportive care during pediatric hematopoietic stem cell transplantation: beyond infectious diseases. A report from workshops on supportive care of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Hematopoietic stem cell transplantation (HSCT) is currently the standard of care for many malignant and nonmalignant blood diseases. As several treatment-emerging acute toxicities are expected, optimal supportive measurements critically affect HSCT outcomes. The paucity of good clinical studies in supportive practices gives rise to the establishment of heterogeneous guidelines across the different centers, which hampers direct clinical comparison in multicentric studies. Aiming to harmonize the supportive care provided during the pediatric HSCT in Europe, the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) promoted dedicated workshops during the years 2017 and 2018. The present paper describes the resulting consensus on the management of sinusoidal obstructive syndrome, mucositis, enteral and parenteral nutrition, iron overload, and emesis during HSCT.

Efficacy of a Spanish-Language Self-Administered Stress Management Training intervention for Latinas undergoing chemotherapy

BACKGROUND

Cancer patients often report increased stress during chemotherapy. Stress management training has been shown to reduce this adverse outcome, but few interventions exist for Spanish-speaking Hispanic and Latina women (Latinas).

METHODS

Following community feedback (including focus groups/in-depth interviews), we transcreated the Spanish-Language Self-Administered Stress Management Training (SL-SAT) intervention based on our previously developed and implemented English-based intervention. Latinas about to begin chemotherapy were randomized to SL-SAT (n = 121) or usual care (n = 119). A Spanish-speaking interventionist met with SL-SAT participants who received the SL-SAT toolkit containing instructions in 3 well-established stress management techniques (deep breathing, progressive muscle relaxation and guided imagery, and use of coping self-statements). Usual care participants received an educational booklet about coping with chemotherapy. All patients were instructed by nurses on their chemotherapy medications and given a resource listing of local support groups. Outcomes were obtained at baseline, and 7 and 13 weeks after starting chemotherapy. Primary outcomes included anxiety and depression, cancer-related distress, emotional well-being, and spiritual well-being. Secondary outcomes included functional well-being, social/family well-being, physical well-being, symptom severity, and self-efficacy for managing stress. Data were analyzed by using mixed models.

RESULTS

In both groups, improvements were observed in emotional well-being (P = .01), and declines were observed in functional well-being (P = .05), and physical well-being (P < .0001). Symptom severity increased across the follow-up period (P < .001).

CONCLUSIONS

To be effective, stress management interventions for Latinas receiving chemotherapy may necessitate more attention from an interventionist, delivery of the intervention over a longer interval, and/or a group-based format.

2016 updated MASCC/ESMO consensus recommendations: Anticipatory nausea and vomiting in children and adults receiving chemotherapy

PURPOSE

We aimed to update the 2011 recommendations for the prevention and treatment of anticipatory nausea and vomiting in children and adults receiving chemotherapy.

METHODS

The original systematic literature search was updated. Randomized studies were included in the evidence to support this guideline if they as follows: were primary studies published in a journal in full text (i.e., abstracts, letters, book chapters, and dissertations were excluded); published in English; evaluated an intervention for the prevention or treatment of anticipatory nausea and vomiting; reported the proportion of patients experiencing complete control of anticipatory nausea and vomiting consistently and; included at least ten participants per study arm for comparative studies and at least ten participants overall for noncomparative studies.

RESULTS

Eighty-eight new citations were identified. Of these, nine were brought to full-text screening; none met inclusion criteria. The guideline panel continues to recommend that anticipatory nausea and vomiting are best prevented through optimization of acute and delayed phase chemotherapy-induced nausea and vomiting control. Benzodiazepines and behavioral therapies, in particular progressive muscle relaxation training, systematic desensitization and hypnosis, continue to be recommended for the treatment of anticipatory nausea and vomiting.

CONCLUSIONS

No new information regarding interventions aimed at treating or preventing ANV that met criteria for inclusion in this systematic review was identified. The 2015 MASCC recommendations affirm the content of the 2009 MASCC recommendations for the prevention and treatment of anticipatory nausea and vomiting.

Systematic Desensitization and the Reduction of Anxiety

This article provides detailed information on systematic desensitization. The procedures of imaginal desensitization with individuals are described in detail, so that the reader can apply the most frequently used form of desensitization. Variants of group, in vivo, massed, and self-administered desensitization are briefly described to extend the reader's use of desensitization. Additionally, guidelines for the appropriate selection and use of desensitization are outlined, and a sampling of research findings with a diversity of anxiety and stress disorders is presented.

Anticipatory Nausea and Vomiting Among Ovarian, Lymphoma, and Breast Cancer Patients Receiving Chemotherapy: Implications for Behavioural Treatment

Cancer patients undergoing chemotherapy frequently experience anticipatory distress before treatment sessions. Eighty-six cancer patients (ovarian, lymphoma and breast) were assessed to determine the prevalence of anticipatory nausea and vomiting (ANV). Approximately one patient in three reported anticipatory nausea (AN), and of these 6 also experienced anticipatory vomiting (AV). Several patients reported anticipatory anxiety without any sensation of nausea. Clinically the notion of anticipatory distress may be more fruitful so that the problem of pretreatment anxiety is also addressed. Generally, AN was rated as moderate or worse in severity, occurred fairly consistently, and often began well before arrival at hospital on treatment day. It is suggested that future research should endeavour to link more closely the topography of the problem and the intervention techniques employed, as well as evaluating a broader range of possible interventions.

Guideline for the prevention and treatment of anticipatory nausea and vomiting due to chemotherapy in pediatric cancer patients

This guideline provides an approach to the prevention and treatment of anticipatory chemotherapy-induced nausea and vomiting (CINV) in children. It was developed by an international, inter-professional panel using AGREE II methods and is based on systematic literature reviews. Evidence-based recommendations for pharmacological and non-pharmacological interventions to prevent and treat anticipatory CINV in children receiving antineoplastic agents are provided. Gaps in the evidence used to support the recommendations are identified. The contribution of this guideline to anticipatory CINV control in children requires prospective evaluation.

Effects of Psycho-Oncologic Interventions on Emotional Distress and Quality of Life in Adult Patients With Cancer: Systematic Review and Meta-Analysis

Purpose

This study aimed to evaluate the effects of psycho-oncologic interventions on emotional distress and quality of life in adult patients with cancer.

Methods

Literature databases were searched to identify randomized controlled trials that compared a psycho-oncologic intervention delivered face-to face with a control condition. The main outcome measures were emotional distress, anxiety, depression, and quality of life. Outcomes were evaluated for three time periods: post-treatment, ≤ 6 months, and more than 6 months. We applied standard meta-analytic techniques to analyze both published and unpublished data from the retrieved studies. Sensitivity analyses and meta-regression were used to explore reasons for heterogeneity.

Results

We retrieved 198 studies (covering 22,238 patients) that report 218 treatment-control comparisons. Significant small-to-medium effects were observed for individual and group psychotherapy and psychoeducation. These effects were sustained, in part, in the medium term (≤ 6 months) and long term (> 6 months). Short-term effects were evident for relaxation training. Studies that preselected participants according to increased distress produced large effects at post-treatment. A moderator effect was found for the moderator variable “duration of the intervention,” with longer interventions producing more sustained effects. Indicators of study quality were often not reported. Small-sample bias indicative of possible publication bias was found for some effects, particularly with individual psychotherapy and relaxation training.

Conclusion

Various types of psycho-oncologic interventions are associated with significant, small-to-medium effects on emotional distress and quality of life. These results should be interpreted with caution, however, because of the low quality of reporting in many of the trials.

Use and helpfulness of self-administered stress management therapy in patients undergoing cancer chemotherapy in community clinical settings

The purpose of this multicenter longitudinal randomized controlled trial was to examine the efficacy of self-administered stress management training (SSMT) in improving quality of life and reducing psychological distress among patients receiving cancer chemotherapy. Participants were randomized to SSMT (n = 111) or usual psychosocial care only (n = 109). Mixed linear modeling demonstrated no significant improvements in primary outcome measures; however, participants assigned to SSMT reported using significantly more relaxation techniques (p < 0.0001), showed improvements on emotional adjustment scores, and demonstrated a stabilizing effect on the functional adjustment scores. Findings highlight the usefulness of SSMT in community clinical settings.

Pre-intervention distress moderates the efficacy of psychosocial treatment for cancer patients: a meta-analysis

This meta-analysis examined whether effects of psychosocial interventions on psychological distress in cancer patients are conditional upon pre-intervention distress levels. Published articles and unpublished dissertations between 1980 and 2005 were searched for interventions reporting the Hospital Anxiety and Depression Scale (HADS) or the Spielberger State-Trait Anxiety Inventory (STAI). Multilevel mixed-effects modeling was used to meta-analyze effect-sizes separately for the HADS (27 trials, 2,424 patients) and STAI (34 trials, 2,029 patients). Pre-intervention distress significantly moderated intervention effects, explaining up to 50% of the between-study effect-size variance: effects on anxiety and depression were generally negligible when pre-intervention distress was low and pronounced when it was high. These results could not be explained by differences in intervention type, setting, dose, and whether intervention was targeted at distressed patients. Psychosocial interventions may be most beneficial for cancer patients with elevated distress. Future research should identify which treatment components are most effective for these patients to facilitate optimal treatment tailoring and cost-effective health care.

Nonpharmacologic strategies for managing common chemotherapy adverse effects: a systematic review

PURPOSE

Adverse effects of chemotherapy can be severe and can have a significant impact on a person's quality of life. With chemotherapy treatment increasingly administered in the ambulatory setting, there is a need for patients to be informed about effective self-care strategies to manage treatment adverse effects. Advice for patients needs to be based on evidence. This systematic review provides an overview of the intervention research in this area as well as an effectiveness review of nonpharmacologic (self-care) strategies evaluated in high-quality randomized controlled trials (RCTs).

METHODS

An extensive literature search was conducted to identify RCTs relating to self-care strategies for reducing nausea/vomiting, constipation, diarrhea, fatigue, hair loss, or mucositis. Relevant studies published in peer-reviewed journals between 1980 and August 2007 were included. Study characteristics, results and methodologic quality were examined. High-quality RCTs were further analyzed to establish the effectiveness of specific self-care strategies.

RESULTS

The search identified 77 RCTs. Findings from RCTs of reasonable quality provide limited support for cognitive distraction, exercise, hypnosis, relaxation, and systematic desensitization to reduce nausea and vomiting, psycho-education for fatigue, and scalp cooling to reduce hair loss.

CONCLUSION

Although some strategies seem promising, the quality of the RCTs was generally quite low, making it difficult to draw conclusions about the effectiveness of self-care strategies. Future studies require better design and reporting of methodologic issues to establish evidence-based self-care recommendations for people receiving chemotherapy.

"Does one size fit all?" moderators in psychosocial interventions for breast cancer patients: a meta-analysis

BACKGROUND

A variety of psychosocial interventions have been developed to promote better adjustment to breast cancer (BC) and their efficacy has been demonstrated repeatedly. However, the effect sizes (ES) vary considerably across studies.

PURPOSE

This article intends to shed light on potential moderators of intervention efficacy for BC patients, such as the intervention type (e.g., education, supportive), the composition of the sample (only BC patients or BC mixed with other cancer types), and the practitioner of the intervention (psychologist, nonpsychologist).

METHODS

Fifty-six randomized-controlled studies investigating the effectiveness of psychosocial interventions with adult BC patients were meta-analytically reviewed.

RESULTS

The overall ES of d = 0.26 was similar to previous meta-analyses and moderated by several variables. The ES varied notably based on the composition of the sample, the profession offering the intervention, and the type of intervention. Studies with samples consisting of only BC patients and studies with nonpsychologist-led interventions showed lower ES. Psychoeducation yielded the strongest ES. These moderators maintained their significance even when controlling for the nature of the control group, the format of the intervention, the timing of the intervention, or the stage of disease.

CONCLUSIONS

These results suggest that among current interventions, psychoeducation is a treatment of choice for BC patients, preferably prior to surgery and led by individuals with a medical expertise. Other psychosocial interventions appear most effective when administered individually and led by a psychologist. In addition, there is a need for improved psychosocial interventions to enhance the present ES for women with BC.

Massage Relieves Nausea in Women with Breast Cancer Who Are Undergoing Chemotherapy

OBJECTIVES

The aim of the present study was to examine the effect of massage on nausea, anxiety, and depression in patients with breast cancer undergoing chemotherapy.

DESIGN

This work was a single-center, prospective, randomized, controlled trial.

SETTINGS/LOCATION

This study was conducted in an oncology clinic, in a hospital in southwestern Sweden.

SUBJECTS

Thirty-nine (39) women (mean age = 51.8) with breast cancer undergoing chemotherapy were enrolled.

INTERVENTIONS

The patients were randomly assigned to a massage therapy group (20 minutes of massage on five occasions) or a control group (five 20-minute visits).

OUTCOME MEASURES

All patients recorded nausea and anxiety on the Visual Analogue Scale before and after each intervention. They also completed the Hospital Anxiety and Depression Scale.

RESULTS

Massage treatment significantly reduced nausea compared with control treatment (p = 0.025) when improvement was measured as a percentage of the five treatment periods. Differences in anxiety and depression between the two treatment regimes could not be statistically demonstrated.

CONCLUSIONS

This study complements previous studies on the effect of massage and supports the conclusion that massage reduces nausea in these patients.

Pilot study of a self-administered stress management and exercise intervention during chemotherapy for cancer

GOALS OF WORK

This pilot project explored the feasibility, safety, and effectiveness of a self-administered exercise and stress management intervention for cancer patients receiving chemotherapy.

PATIENTS AND METHODS

Thirty-nine of 56 eligible patients (acceptance =69%) with a variety of solid tumors volunteered for the study. Participants were advised to exercise 20-40 min at 50-75% estimated heart rate reserve 3-5 times per week. In addition, patients were provided with instruction and written materials regarding stress management techniques. Follow-up data were collected during regularly scheduled outpatient visits at the start of the second, third, and fourth chemotherapy cycles using diary entries and the same questionnaires previously administered at baseline.

MAIN RESULTS

Twenty-four of 39 patients (62%) completed all study requirements. These participants completed 438 of the 678 exercise sessions assigned (adherence =62%). Of the stress management techniques, positive thinking most practiced most frequently (48%), followed by deep breathing (38%) and active relaxation (37%). Paired t tests, comparing baseline values with final recorded values, indicated a significant improvement over time in bodily pain (p<0.03) and mental health (p<0.04) subscale scores. Participants' evaluations of the combined intervention were favorable: 90% felt it was helpful to them and 100% would recommend it to another patient.

CONCLUSIONS

A self-administered intervention combining aerobic exercise and stress management was acceptable and safe for cancer patients receiving chemotherapy. Preliminary data demonstrating intervention efficacy should be confirmed in subsequent randomized clinical trials.

Efficacy and costs of two forms of stress management training for cancer patients undergoing chemotherapy

PURPOSE

Professionally administered psychosocial interventions have been shown to improve the quality of life of cancer patients undergoing chemotherapy. The present study sought to improve access to psychosocial interventions during chemotherapy treatment by evaluating the efficacy and costs of a patient self-administered form of stress management training that requires limited professional time or experience to deliver.

PATIENTS AND METHODS

Four hundred eleven patients about to start chemotherapy were randomly assigned to receive usual psychosocial care only, a professionally administered form of stress management training, or a patient self-administered form of stress management training. Quality-of-life assessments were conducted before randomization and before the second, third, and fourth treatment cycles. Intervention costs were estimated from both payer and societal perspectives.

RESULTS

Compared with patients who received usual care only, patients receiving the self-administered intervention reported significantly (P < or = .05) better physical functioning, greater vitality, fewer role limitations because of emotional problems, and better mental health. In contrast, patients who received the professionally administered intervention fared no better in terms of quality of life than patients receiving usual care only. Costs of the self-administered intervention were estimated to be 66% (from a payer perspective) to 68% (from a societal perspective) less than the average costs of professionally administered psychosocial interventions for patients starting chemotherapy.

CONCLUSION

Evidence regarding the efficacy and favorable costs of self-administered stress management training suggests that this intervention has the potential to greatly improve patient access to psychosocial intervention during chemotherapy treatment.

The role of behavioral conditioning in the development of nausea

Literature related to the prevalence and etiology of anticipatory nausea and vomiting associated with chemotherapy is reviewed. Physiologic causes and psychological factors, including expectations, beliefs, and conditioning, are examined to help explain these phenomena. The efficacy of pharmacologic and behavioral treatments is discussed. Similarities between the experience of anticipatory nausea and vomiting and morning sickness suggest that the conditioning model may be relevant to understanding the development of pregnancy-related nausea.

The effectiveness of relaxation training in reducing treatment-related symptoms and improving emotional adjustment in acute non-surgical cancer treatment: a meta-analytical review

Cancer patients often have to deal with severe side effects and psychological distress during cancer treatment, which have a substantial impact on their quality of life. Among psychosocial interventions for reducing treatment-related side effects, relaxation and imagery were most investigated in controlled trials. In this study, meta-analytic methods were used to synthesize published, randomized intervention-control studies aiming to improve patients' treatment-related symptoms and emotional adjustment by relaxation training. Mean weighted effect sizes were calculated for 12 categories, treatment-related symptoms (nausea, pain, blood pressure, pulse rate) and emotional adjustment (anxiety, depression, hostility, tension, fatigue, confusion, vigor, overall mood). Significant positive effects were found for the treatment-related symptoms. Relaxation training also proved to have a significant effect on the emotional adjustment variables depression, anxiety and hostility. Additionally, two studies point to a significant effect of relaxation on the reduction of tension and amelioration of the overall mood. Intervention features of the relaxation training, the time the professional spent with the patient overall (intervention intensity) and the schedule of the intervention (offered in conjunction with or independent of medical treatment to the cancer patient) were relevant to the effect of relaxation on anxiety. The interventions offered independently of medical treatment proved to be significantly more effective for the outcome variable anxiety. Relaxation seems to be equally effective for patients undergoing different medical procedures (chemotherapy, radiotherapy, bone marrow transplantation, hyperthermia). According to these results relaxation training should be implemented into clinical routine for cancer patients in acute medical treatment.

Behavioral intervention for cancer treatment side effects

The use of increasingly aggressive methods of cancer treatment during the last 20 years has brought clinical attention to the need for more effective management of pain, nausea, and other aversive side effects of state-of-the-art cancer therapy. One of the most promising approaches to effective management is nonpharmacologic intervention based on behavioral research and theory. The purpose of this review is to examine the effectiveness of behavioral intervention methods in the control of aversive side effects of cancer treatments. Fifty-four published studies using a variety of research designs were identified for review. Results indicated the following: 1) Behavioral intervention can effectively control anticipatory nausea and vomiting in adult and pediatric cancer patients undergoing chemotherapy; however, the evidence for the efficacy of behavioral intervention to control post-chemotherapy nausea and vomiting is less clear. 2) Behavioral intervention integrating several behavioral methods can ameliorate anxiety and distress associated with invasive medical treatments. 3) Although a variety of behavioral methods have been shown to reduce acute treatment-related pain, there is increasing evidence that these methods are not equally effective. Hypnotic-like methods, involving relaxation, suggestion, and distracting imagery, hold the greatest promise for pain management. Unfortunately, research is scant on the use of behavioral intervention to control prolonged pain associated with invasive medical procedures. It is clear that the application of behavioral theory and methods has an important place in the care of patients undergoing invasive cancer treatments.

The effects of psychological therapies under clinically representative conditions: a meta-analysis

Recently, concern has arisen that meta-analyses overestimate the effects of psychological therapies and that those therapies may not work under clinically representative conditions. This meta-analysis of 90 studies found that therapies are effective over a range of clinical representativeness. The projected effects of an ideal study of clinically representative therapy are similar to effect sizes in past meta-analyses. Effects increase with larger dose and when outcome measures are specific to treatment. Some clinically representative studies used self-selected treatment clients who were more distressed than available controls, and these quasi-experiments underestimated therapy effects. This study illustrates the joint use of fixed and random effects models, use of pretest effect sizes to study selection bias in quasi-experiments, and use of regression analysis to project results to an ideal study in the spirit of response surface modeling.

Anticipatory nausea and vomiting: broadening the scope of psychological treatments

Anticipatory nausea and vomiting, as a side-effect of cancer chemotherapy, is a well-recognised phenomenon known to affect a substantial minority of patients. Although explicable using a conditioning model, it may have a complex aetiology with affective and cognitive elements as well as specific pharmacological factors playing a role in its onset and maintenance. It is amenable to treatment using psychological techniques but to treat successfully it is important to understand the aetiology and formulate treatment plans according to those factors that make a significant contribution to the cause. It is suggested here that a behavioural model provides an over-simplistic conceptualization and that cognitive factors play a central role in onset. As such, treatment plans need to be broader in scope by focusing on a range of strategies to enhance coping and particularly cognitive coping techniques. More recently there has also been some indication that psychological factors may contribute to symptoms of nausea and vomiting occurring during or after chemotherapeutic infusion. Should this effect be replicated, the scope for psychological treatments within the care of patients receiving chemotherapy would be widened.

Cognitive distraction and relaxation training for the control of side effects due to cancer chemotherapy

Sixty cancer chemotherapy patients were randomly assigned to one of six conditions formed by a 3(cognitive distraction, relaxation training, no intervention) x 2(high anxiety, low anxiety) factorial design. All patients were followed for five consecutive chemotherapy sessions. Outcome measures included patient reports, nurse observations, and physiological indices. Results indicated that distraction patients reported less nausea prior to chemotherapy and lower systolic blood pressures after chemotherapy than controls. Relaxation training patients reported less nausea prior to chemotherapy and exhibited lower systolic and diastolic blood pressures after chemotherapy than control patients. There were no significant differences between distraction and relaxation training patients on any measure. Patients with high initial levels of anxiety exhibited continually elevated levels of distress throughout the chemotherapy experience; however, anxiety level did not interact with the effectiveness of the treatment interventions. Overall, the data support the use of both cognitive distraction and relaxation training for reducing the distress of chemotherapy with both high and low-anxiety patients and suggest that at least some of the effects of relaxation training can be achieved with distraction alone.

Predicting development of anticipatory nausea in cancer patients: prospective examination of eight clinical characteristics

An algorithm based on learning theory and previous research for predicting which cancer patients would develop nausea in anticipation of chemotherapy treatments was tested. Patients with four or more of the following eight characteristics after their first treatment were predicted to develop anticipatory nausea (AN) by their fourth chemotherapy treatment: experienced nausea and/or vomiting after first treatment; nausea after treatment described as "moderate, severe, or intolerable;" vomiting after treatment described as "moderate, severe, or intolerable;" less than 50 yr of age; a susceptibilty to motion sickness; feeling warm or hot all over after treatment; sweating following treatment; feelings of generalized weakness following treatment. The characteristics significantly predicted subsequent anticipatory nausea development (p less than .01) by their fourth treatment in 355 consecutive cancer patients. Results were independent of the type of cancer being treated. The accuracy of the prediction was less specific than prior research, 34% of patients predicted to develop AN did so, compared to 16% of the total sample. Results are consistent with a learned etiology for the development of anticipatory side effects and support the importance of predictive methodologies in investigating mechanisms of anticipatory nausea development.

Psychological aspects of cancer and chemotherapy

Research in the psychological aspects of cancer and chemotherapy has reached an exciting stage of development. More acceptable standards of scientific rigour are being applied to thinking and research, spanning a wide range of important issues from prognostic indicators to the evaluation of treatment trials. It is important to remember that patients do not exist in isolation and that the impact of disease and treatment is also felt by their care givers. The burden which falls on spouses and other primary carers and the importance of their contribution to patients' adaptation to illness should not be underestimated. By the same token the emotional demands particularly on nursing and junior medical staff are increasingly recognized with developing interest in optimal means of providing staff support. Thus the field is still expanding. It requires the continuing collaborative effort of a wide range of professional disciplines to improve our understanding of the psychological aspect of oncology for all cancer patients and those who care for them.

Modifiability of trait anxiety and neuroticism: a meta-analysis of the literature

It is argued that personality scales of neuroticism and anxiety are tapping the same personality trait and that this is a risk factor for neurotic disorders. To see whether this trait is modifiable, a meta-analysis was carried out of therapy outcome studies which included a measure of trait anxiety or neuroticism as a dependent measure. This meta-analysis showed that all psychological therapies are to some extent effective. However, rational-emotive and related therapies produced particularly large reductions in trait anxiety/neuroticism (around 1.25 standard deviations). The possibility that rational-emotive education programmes could be used to lower trait anxiety/neuroticism as a preventive measure is discussed.

Ratings of cancer chemotherapy toxicity by oncologists, nurses, and pharmacists

In order to examine the perceived toxicity of commonly used drug regimens for cancer chemotherapy, eight oncologists, twelve nurses, and five pharmacists rated the toxicity of 30 different drug combinations. Although the correlations revealed a high degree of agreement, the oncologists' ratings and the nurses' ratings differed systematically at the lower- and the higher-toxicity levels. This was most readily described by a "regression effect," wherein oncologists' ratings appear to regress toward the mean relative to the nurses' ratings. The perception of both toxicity and the importance of side effects such as nausea and vomiting may be substantially different between physicians and nurses, and hence, has important implications for how patients communicate these to the various health care professionals.
