Psychosocial care in cancer

A mixed method feasibility and acceptability study of a flexible intervention based on acceptance and commitment therapy for patients with cancer

Propose

This study aimed to propose an innovative, open, and circular program that combines acceptance and commitment therapy (ACT) and mindfulness practices. We assessed its feasibility, acceptability, and first signs of its effect on psychological wellbeing in cancer support treatment.

Methods

A single-center, single-arm, uncontrolled study was performed. Forty adult patients with non-metastatic prostate or breast cancer, newly diagnosed or undergoing treatment (chemotherapy, radiotherapy, hormone therapy), were recruited. Three cycles of three MAEva program sessions (MAEva: Mindfulness meditation, Acceptance, and Commitment to values program) over nine consecutive weeks were proposed. During the total of 12 weeks of follow-up, after attending the first session, patients were free to attend subsequent sessions.

Results

Adherence to the study was high, with participation in an average of 6.8 out of nine sessions. A total of eight patients attended all sessions over the three cycles, and 90% participated in at least one cycle. Furthermore, attendance was associated with a statistically significant improvement in Quality of Life (QoL). Each additional session was associated with a mean increase in overall QoL score of more than one point (β = 1.09 [0.13; 2.04], p = 0.02). The fatigue dimensions decreased with session attendance: physical (β = -2.24 [-3.63; -0.85]), emotional (β = -2.60 [-4.11; -1.09]), and interference with daily life (β = -2.33 [-3.95; -0.72]). The qualitative section demonstrated that patients learned skills and shared their ability to "let go". Patients rated the degree of importance of the program at 8.36/10 (SD ± 1.64).

Conclusion

This study highlights the feasibility and acceptability of an original program that combines ACT and mindfulness practices in cancer patients. Future studies are required to demonstrate the efficacy of the MAEVA program. The MAEva pilot study is registered with ClinicalTrials.gov under the identifier NCT04751201.

Transcranial Magnetic Stimulation for the Treatment of Chemo Brain

This pilot feasibility study aimed to evaluate the effects of transcranial magnetic stimulation (TMS) on chemotherapy-related cognitive impairment (CRCI), and we report here on the first patient.

BACKGROUND

Deleterious cognitive changes due to chemotherapy or CRCI are commonly referred to as "chemo brain". With the increasing survival of cancer patients, this poorly understood and inadequately treated condition will likewise have an increasing toll on individuals and society. Since there is no approved treatment for chemo brain, we have initiated a therapeutic trial using transcranial magnetic stimulation (TMS), a non-invasive brain stimulation technique approved in many countries for the treatment of neurologic and psychiatric conditions like migraine and depression.

CASE PRESENTATION

A 58-year-old woman, diagnosed 7 years prior with left breast cancer, underwent partial mastectomy with sentinel lymph node biopsy. She then received four cycles of adjuvant chemotherapy followed by radiation therapy. Afterwards, she was on tamoxifen for 4 years and then switched to aromatase inhibitors. The patient's CRCI started during chemotherapy and severely impaired her quality of life for an additional two years. In the third year after chemotherapy, the CRCI partially cleared to stabilize to the level at the time of presentation for this trial. The patient continues to have memory difficulties and decreased concentration, which makes multi-tasking very difficult to impossible. She is reliant on memory aids at work and at home. The participant underwent 10 consecutive sessions of TMS during weekdays for 2 weeks. Stimulation was directed to the left dorsolateral prefrontal cortex. After TMS, the participant significantly improved in memory function on neuropsychological testing. While she reported no subjective differences in concentration or memory, she did report an improvement in her sleep. Functional magnetic resonance imaging of the brain before and after TMS showed increased resting-state functional connectivity between the stimulation site and several brain regions. Remarkably, after 6 years of chemo brain and remaining in the same position at work due to her inability to concentrate and multi-task, she applied for and received a promotion 5-6 months after her TMS treatments.

CONCLUSIONS

This first patient in the phase 1 clinical trial testing of TMS for the treatment of "chemo brain" provided important lessons for feasibility and insights into mechanisms of potential benefit.

How can counselling by family physicians on nutrition and physical activity be improved: trends from a survey in Germany

PURPOSE

Cancer and its therapy causes severe symptoms, most of which are amendable to nutrition and physical activity (PA). Counselling on nutrition and PA empowers patients to take part more actively in their treatment. Many cancer patients are yet in need of information on these topics. In this study, we investigate the perception of family physicians (FP) on nutrition and PA in cancer patient care and assess barriers and steps to improve their involvement in counselling on these topics.

METHODS

Based on qualitative content analysis of 5 semi-structured interviews with FP, a questionnaire was developed and completed by 61 German FP.

RESULTS

Most of the FP acknowledged the importance of nutrition and PA during (91.4%) and after (100%) cancer therapy. While many participants were involved in cancer patient care, 65.6% of FP viewed themselves as primary reference person to address these topics. However, a third (32.8%) of FP were unfamiliar with information thereof. Some were unsatisfied regarding timely updates on their patient's treatment course via discharge letters (25.0%) or phone calls (36.2%). FP would like to dedicate more consultation time addressing nutrition and PA than they currently do (p < 0.001).

CONCLUSION

Communication btween healthcare practitioners about mutual cancer patient's treatment must be improved, e.g. utilising electronic communication to quicken correspondence. Acquisition of information on nutrition and PA in cancer patient care needs to be facilitated for FP, approachable by compiling reliable information and their sources. Involvement of FP in structured treatment programs could benefit cancer patient care.

Social relationships and relational pain in brain tumor patients and their partners

Partners play an important role in both the general well-being and the care needs of patients. The dynamic between brain tumor treatment and patients' families is a complex bidirectional relationship. Cancer diagnosis and treatments which leave patients compromised impact the nature and quality of their relationships, and these in turn impact the ability of their partners to care for them. This paper will review the nature of the impact of diagnosis and treatment on relationships and how couples and families respond to the disruption of cancer treatments. The impact of how emotional and social pain effect their relationships and their ability to engage in care will be addressed.

From Distress Screening to Uptake: An Italian Multicenter Study of Cancer Patients

INTRODUCTION

Little consideration is given to the referral and uptake of available supportive services after distress screening. However, identifying the reasons for accepting or refusing help is mandatory for implementing a screening policy. The present study explored the practical usefulness of and potential barriers to the application of distress management.

METHODS

406 cancer patients were consecutively selected and asked to complete the Distress Thermometer (DT) and Problem Check List (PL). All patients with a DT score ≥6 were invited for a post-DT telephone interview with a trained psychologist.

RESULTS

The 112 patients who refused to take part were more often older, retired, at a more advanced stage of illness, and with no previous experience of psychological intervention with respect to those who accepted. Of the 78 patients with a score ≥6 who were referred to the Psycho-Oncology Service, 65.4% accepted the telephone interview. Twenty-two patients rejected the initial invitation immediately for various reasons including logistic difficulties, physical problems, and feeling embarrassed about opening up to a psychologist.

CONCLUSIONS

Our study confirms that screening per sé is insufficient to deal with the problem of distress and that more emphasis should be placed on implementing referral and treatment.

A prospective study of a urine and plasma biomarker test for the prediction of gleason ≥3 + 4 prostate cancer in a mixed cohort

Purpose: Definitive diagnosis of prostate cancer is based on biopsies, a procedure associated with side-effects. The use of biomarkers in blood and urine could potentially help clinicians select patients for whom biopsies are needed. The aim of the study was to test a new urine and plasma biomarker test in detecting medium and high grade prostate cancer.Materials and methods: Blood and urine samples were prospectively collected from 41 patients prior to prostate biopsy or TUR-P and again after 3 months. The cohort included patients with suspicion of prostate cancer and patients with prior prostate cancer diagnosis. The mRNA expression of ten selected genes measured by PCR were used together with clinical data in multiple algorithms for prediction of medium-high grade prostate cancer in prostate biopsies. The testing was originally developed and validated in the USA. The method was transferred to a local Danish laboratory. Medium and high grade cancer was defined as Gleason score ≥ 3 + 4.Results: Using the biomarker test, prior to any prostate procedures, the sensitivity for detecting medium-high grade prostate cancer was 100% and the specificity was 56% and 63%, depending on the cut-off point used. When using the biomarker test, following biopsy or TUR-P, the sensitivity and specificity were reduced to 89% and 28-34% respectively. When comparing results, there was a significant difference (p < 0.05), favoring the test performed prior to the procedures.Conclusions: We were able to predict the presence of medium-high grade prostate cancer, thereby confirming earlier findings of the biomarker test.

Psychological stress and pancreatic cancer patients: a qualitative systematic review protocol

OBJECTIVE

The primary objective of this review is to analyze and synthesize the best available evidence on the experiences and perceptions of psychological stress reported by pancreatic cancer patients at any time point from pre-diagnosis, diagnosis, treatment, post-treatment and/or follow-up care.

INTRODUCTION

A cancer diagnosis is known to be life-threatening, altering and limiting, and negatively affects an individual's activities of daily living. Despite developments in treatment options for pancreatic cancer patients, it represents the highest mortality and morbidity among cancers. Stress is a subjective phenomenon that negatively impacts an individual's psychological and emotional well-being, and interferes with the ability to cope with cancer symptoms and treatments. Identifying a patient's experience of stress could facilitate educational, spiritual and social resources to address his or her emotional and psychological needs.

INCLUSION CRITERIA

Qualitative studies that include individuals with pancreatic cancers, regardless of age, sex or ethnicity, will be considered for inclusion in this review.

METHODS

The databases to be searched include PubMed, CINAHL, Cochrane, Web of Science, Embase, Scopus, BioMed Central and PsycINFO. The search for gray literature will include Biosis, OpenGrey, Open Access Theses and Dissertations, and WorldCat. This systematic review will consider all published and unpublished studies with no date limitations. Selected studies will be assessed for methodological quality by two independent reviewers. Coding will be assigned to synthesize any differences in the experiences and perceptions of psychological stress at four time points. Where textual pooling is not possible, conclusions will be presented in narrative form.

A Randomized Controlled Trial of mHealth Mindfulness Intervention for Cancer Patients and Informal Cancer Caregivers: A Feasibility Study Within an Integrated Health Care Delivery System

Purpose: To assess feasibility and preliminary efficacy of a mobile/online-based (mHealth) mindfulness intervention for cancer patients and their caregivers to reduce distress and improve quality of life (QoL). Material and Methods: Two-arm randomized controlled trial within Kaiser Permanente Northern California targeting cancer patients who received chemotherapy and their informal caregivers. The intervention group received a commercially available mindfulness program for 8 weeks. The wait-list control group received usual care. We assessed feasibility using retention and adherence rates and obtained participant-reported data on distress, QoL, sleep, mindfulness, and posttraumatic growth before and immediately after the intervention. Results: Ninety-seven patients (median age 59 years; female 69%; 65% whites) and 31 caregivers (median age 63 years; female 58%; 77% whites) were randomized. Among randomized participants, 74% of the patients and 84% of the caregivers completed the study. Among those in the intervention arm who initiated the mindfulness program, 65% practiced at least 50% of the days during the intervention period. We observed significantly greater improvement in QoL among patients in the intervention arm compared with controls. Caregivers in the intervention group experienced increased mindfulness compared with controls. Participants appreciated the convenience of the intervention and the mindfulness skills they obtained from the program. Conclusion: We demonstrated the feasibility of conducting a randomized trial of an mHealth mindfulness intervention for cancer patients and their informal caregivers. Results from fully powered efficacy trials would inform the potential for clinicians to use this scalable intervention to help improve QoL of those affected by cancer and their caregivers.

The relationship between role preferences in decision-making and level of psychological distress in patients with head and neck cancer

OBJECTIVE

Is there a relationship between decision-making preferences and psychological distress?

METHODS

Patients who had received treatment for head and neck cancer (HNC) at four institutions within NSW, Australia were invited to complete a single questionnaire.

RESULTS

Five hundred and ninety-seven patients completed the questionnaire. The majority of patients (308, 54%) preferred shared decision making. Significant predictors of a preference towards active decision making were education level (OR 2.1 for tertiary, p < 0.001), primary cancer site (OR 1.9 for thyroid compared to salivary gland, p = 0.024) and gender (OR 1.4 for female, p = 0.028). Mean psychological distress score on Kessler 6 (K6) was 9 (Range: 0-28). Significant predictors of psychological distress were age (p < 0.001), gender (p < 0.001), primary site (p < 0.01), and decision preference (p < 0.01).

CONCLUSION

HNC patients who are either tertiary educated or female are more likely to prefer active involvement in decision-making. Psychological distress is more likely in patients actively involved in decision making, younger patients, and in females.

PRACTICE IMPLICATIONS

Patients experienced paternalistic decision-making, but most preferred active or a shared approached. Clinicians need to be aware of potential for psychological distress in active decision-makers and refer patients for psychosocial support.

Hospitalization-induced exacerbation of the ill effects of chemotherapy on rest-activity rhythm and quality of life of breast cancer patients: a prospective and comparative cross-sectional follow-up study

Chemotherapy administration may result in the disruption of circadian rhythms and impairment of quality of life (QoL) of cancer patients. Nevertheless, we have little knowledge on the long-term consequences of chemotherapy and the effects of hospitalization. In the present study, we employed the two-factor repeated-measure cross-sectional design to determine the effects of chemotherapy and hospitalization on rest-activity (RA) rhythm and QoL of breast cancer patients. Initially, we randomly selected 39 inpatients and 42 outpatients, scheduled to receive six cycles of chemotherapy, from the Regional Cancer Center (RCC), Raipur, India. Finally, 30 patients in each group were included in the current study. We monitored circadian RA rhythm and QoL using wrist actigraphy and QLQ-C30 and QLQ-BR23, respectively, during the 1st (C1), 3rd (C3) and 6th (C6) chemotherapy cycles. Results revealed that with the progression of chemotherapy cycles (from C1 to C6), all rhythm parameters, namely mesor, amplitude, acrophase, rhythm quotient (RQ), circadian quotient (CQ), peak activity (PA), dichotomy index and autocorrelation coefficient, significantly decreased in both cancer in- and outpatients. In both groups of patients and during C1-C6, all functional and global QoL measures of QLQ-C30 and QLQ-BR23 significantly decreased and the symptoms significantly increased, except constipation, body image, sexual functioning and future perspectives in outpatients. The hospitalization exacerbated the problems associated with the RA rhythm and the QoL of the patients. In conclusion, the current study highlighted the negative consequences of hospitalization among inpatients, irrespective of the stage of cancer. We, therefore, recommend that cancer patients should be administered with chemotherapy as outpatients. The proposed protocol might have a covert bearing on the expression of better physiological state leading to satisfactory treatment outcomes.

Psychosocial Distress and Distress Screening in Multidisciplinary Head and Neck Cancer Treatment

Psychosocial distress screening (DS) for cancer and head and neck cancer (HNC) patients is rapidly becoming the standard of care. DS is of particular importance for patients with HNC, given their heightened incidence of distress, depression, anxiety, suicide, quality of life impacts, and negative medical outcomes. In the absence of DS, distress is frequently missed in oncology settings. However, when identified, distress is highly responsive to treatment, with cognitive behavioral and behavioral medicine interventions demonstrating evidence of efficacy. Multidisciplinary HNC teams are uniquely positioned to implement effective DS programs and treatment tailored to HNC patients' psychological and medical vulnerabilities.

Acute Leukemia Patients' Needs: Qualitative Findings and Opportunities for Early Palliative Care

CONTEXT

Patients with acute leukemias likely have needs that palliative care can respond to, yet little is known about specific challenges they face, particularly during active treatment. We examined acute myeloid leukemia (AML) patients' expressed challenges and supports after intensive induction chemotherapy.

OBJECTIVES

We aimed to understand opportunities for palliative care interventions in this population.

METHODS

We conducted a qualitative study of AML patients with high-risk disease at Duke University Hospital, Durham, NC. Patients were interviewed about care experiences approximately 3 months after treatment initiation. Multiple coders used descriptive content analysis to identify common and recurrent themes.

RESULTS

We analyzed 22 patient transcripts. Sample demographics included 10 (45.5%) females, 12 (54.5%) males, mean age 62 (SD 10.9), 19 (86.4%) non-Hispanic white, and three (13.6%) nonwhite/non-Hispanic. All had high-risk disease, by age, relapse status, or molecular markers. We identified four themes in our analysis: physical symptoms, psychological issues, uncertainty regarding prognosis, and patients' sources of support. Specific challenges noted by patients included feelings of helplessness/hopelessness, activity restriction, fatigue, fevers, caregiver stress, and lack of clarity regarding treatment decision making.

CONCLUSION

AML patients face substantial challenges regarding physical symptoms, psychological distress, and uncertainty regarding prognosis. These challenges signal needs for which palliative care in high-risk AML patients may help. Our findings highlight opportunities to develop targeted palliative care interventions addressing unmet needs in AML patients.

Making meaning of cancer: A qualitative analysis of oral-digestive cancer survivors' reflections

This qualitative study aimed to confirm and extend research on meaning making after cancer. In all, 119 adults aged 41 to 88 years (M = 65.50 years and standard deviation = 9.16 years) were interviewed 12 months after diagnosis of oral-digestive cancers. About half tried to understand why they got cancer (43%) and said that cancer changed their view of life (53%). Most (75%) reported that previous life experiences helped them cope with cancer. Cancer survivors made meanings in the areas of existential, social, and personal domains with both positive and negative content. Practitioners may wish to examine meaning making in these areas for those in distress after cancer.

Preparing the workforce for integrated healthcare: A systematic review

Integrated healthcare is recommended to deliver care to individuals with co-occurring medical and mental health conditions. This literature review was conducted to identify the knowledge and skills required for behavioral health consultants in integrated settings. A review from 1999 to 2015 identified 68 articles. Eligible studies examined care to the U.S. adult population at the highest level of integration. The results provide evidence of specific knowledge of medical and mental health diagnoses, screening instruments, and intervention skills in integrated primary care, specialty medical, and specialty mental health. Further research is required to identify methods to develop knowledge/skills in the workforce.

Cognitive impairment among prostate cancer patients: An overview of reviews

To identify and clarify definitions and methods of measuring cancer-related cognitive impairment among prostate cancer patients treated with androgen deprivation therapy (ADT) and to assess the incidence and prevalence of cognitive impairment. A systematic review of Medline, EMBASE, PubMed, PsycINFO and CINAHL up to December 2015 was undertaken to identify English-language reviews. A total of 28 reviews were identified describing 20 primary studies. There were no studies of incidence. Reported prevalence rates varied between 10% and 69%. Cognitive domains impaired by ADT included: verbal memory, visuospatial ability and executive functions. Cognitive impairment was infrequently defined and four definitions were reported. A variety of measures and methods were used to assess cognitive function including neuropsychological tests, self-report measures and clinical assessments. The finding that, often, one measure was used to assess more than one aspect of cognition is likely to have contributed to imprecise estimates. There is a need to agree a definition of cognitive impairment in the clinical epidemiology of cancer and to standardise the selection of measures in order to aid accurate assessment and fair comparisons across studies regarding the prevalence of cognitive impairment among prostate cancer patients.

The role of oncology nurse navigators in facilitating continuity of care within the diagnostic phase for adult patients with lung cancer

Objective

The objective of this study was to explore the role of oncology nurse navigators (ONN) in facilitating continuity of care for adult lung cancer patients during the diagnostic phase of cancer care.

Design

A phenomenological approach was used and involved semi-structured patient interviews and an oncology nurse navigators' focus group.

Results

Eight individuals participated, including four adult patients with lung cancer and four oncology nurse navigators. Themes regarding the organizational functions of the ONN role in facilitating continuity of care were identified: patient-focused care, needs assessments, shared decision-making, accessibility, and eliminating barriers.

Conclusion

Awareness of the organizational functions of the ONN role could be used to create core areas of practice within nursing training modules to provide consistent and patient-centred continuity of care.

Biological Basis for the Clustering of Symptoms

OBJECTIVES

Identification of biologic pathways of symptom clusters is necessary to develop precision therapies for distressing symptoms. This review examined extant literature evaluating relationships between biomarkers and symptom clusters in cancer survivors.

DATA SOURCES

PubMed, CINAHL, Web of Science and Cochrane Library were searched using terms "biological markers" or "biomarkers" and "symptom cluster" or "symptom complex" or "multiple symptoms."

CONCLUSION

Biomarkers related to inflammation (eg, cytokines) were the most studied and showed the most significant relationships with clusters of symptoms. This review suggests that clustering of symptoms related to cancer or cancer therapy is linked to immune/inflammatory pathways.

IMPLICATIONS FOR NURSING PRACTICE

Understanding the etiology of symptom clusters may guide future nursing interventions for symptom management.

Psychosocial issues in post-treatment cancer survivors: Desire for support and challenges in identifying individuals in need

PURPOSE

The ongoing and late effects of cancer treatment can interfere with quality of life and adoption of healthy behaviors, thus potentially impairing recovery and survival. Developing effective methods to identify individuals in need of support is crucial in providing comprehensive, ongoing care and ensuring optimal use of limited resources. The current study provides an examination of long-term survivors' reports of psychosocial issues, their desire for follow-up, and the role of widely used distress-screening measures for identifying survivors who desire help.

METHOD

317 cancer survivors (M age = 62.98 years, female = 70%, Md years since treatment = 7.5 years, mixed diagnoses) completed measures of psychosocial adjustment and quality of life as well as a checklist of psychosocial issues on which they indicated whether they would like to speak with a health professional regarding each issue.

RESULTS

Participants reported an average of 1.7 psychosocial issues. Only a minority desired to speak to a health professional; however, those desiring follow-up reported significant impairments in adjustment and quality of life. Though far from adequate as a stand-alone measure, area under the curve and regression analysis suggested a combination of the distress thermometer and number of psychosocial issues may be the best assessment of those desiring follow-up assistance.

CONCLUSION

These results indicate that there is a need for a more sophisticated system of assisting survivors that takes into account issues, symptoms, and motivation for help. The present study is important in guiding the development of effective survivorship care and contributing to the growing literature describing the adjustment and care needs of survivors.

The five steps of comprehensive psychosocial distress screening

Despite the growing recognition of the impact psychosocial distress has on the quality of life of patients with cancer, the implementation of the National Comprehensive Cancer Network (NCCN) Distress Management Guidelines and the mandate of evidence-based policy for routine distress screening continue to lag. To speed adoption of the guideline, the American Psychosocial Oncology Society (APOS) and Yale School of Nursing (YSN) launched the Screening for Psychosocial Distress Program in 2014. The program resulted in the development of five steps necessary to carry out routine psychosocial distress screening. The steps are consistent with the NCCN Distress Management Guidelines and the new criterion for accreditation by the American College of Surgeons (ACS) Commission on Cancer as of 2015. These five steps are as follows: (1) screening, (2) evaluating, (3) referring, (4) following up, and (5) documenting and quality improvement. The purpose of this article is to summarize the detailed procedure of the five steps for cancer care professionals-including oncologists, nurses, psychiatrists, psychologists, and social workers-so they can manage psychosocial distress efficiently in their own clinical environments.

Are there specific health-related factors that can accentuate the risk of suicide among men with prostate cancer?

Purpose

The aim of this study was to explore if there were some specific factors pertinent to health-related quality of life (HRQoL) that could affect self-experienced suicide ideation in men with prostate cancer (PCa).

Methods

Questionnaires containing 45 items were distributed to members of the Swedish Prostate Cancer Federation in May 2012. Out of 6,400 distributed questionnaires, 3,165 members (50 %) with PCa completed the questionnaires. Those members expressed their experienced HRQoL and experienced suicide ideation using VAS-like scales as well as multiple-choice questions. Both descriptive and analytical statistical methods were employed. A regression model was used to explore the relationship between experienced health-related quality of life and experienced suicide ideation.

Results

Generally, the respondents rated their self-experienced health-related quality of life as good. About 40 % of the participants had experienced problem with incontinence, and 23 % had obstructions during miction. About 7 % of the respondents experienced suicidal ideation, at least sometime. The regression model showed statistically significant relationships between suicide ideation, on the one hand, and lower self-rated health-related quality of life (P < 0.001), physical pain (P = 0.04), pain during miction (P = 0.03), and low-rated mental / physical energy (P = 0.03), on the other.

Conclusion

It is quite necessary to know which specific disease and treatment-related problems can trigger suicide ideations in men with prostate cancer and to try to direct treatment, care, and psychosocial resources to alleviate these problems in time.

Psychosocial therapies for patients with cancer: a current review of interventions using psychoneuroimmunology-based outcome measures

BACKGROUND

As part of a new standard of quality cancer care, the Institute of Medicine has recommended inclusion of therapies that address psychosocial needs of cancer patients. A range of psychosocial therapies for managing acute and chronic stress have been developed for patients with cancer, based on the scientific framework of psychoneuroimmunology (PNI). The current review aimed to identify studies of new and emerging PNI-based psychosocial therapies in patients with cancer that have used neuroendocrine-immune biomarkers as outcomes. Specifically, this review aimed to evaluate studies based on the cancer populations involved, types of psychosocial therapies, and PNI measures employed.

METHOD

Methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The PubMed, EMBASE, PsychINFO, CINAHL, and Google Scholar online databases were searched using combinations of keywords obtained from previous reviews of psychosocial interventions. Studies from 2001 to 2012 were included if they ( : ) were published in English, ( : ) used experimental or quasi-experimental designs, ( : ) evaluated psychosocial therapies, ( : ) involved cancer patients, and ( : ) reported results on at least one neuroendocrine or immune outcome measure. The search strategy identified 403 records and 2 stages of screening were used to eliminate irrelevant studies.

RESULT

A total of 24 cancer-specific studies of psychosocial therapies that used PNI-based outcome measures were included in this review. Most studies included early-stage breast cancer patients, and 2 major types of therapies emerged, cognitive-behavioral therapies and complementary medical therapies. Durations of interventions ranged widely, from 1.3 hours over a single week to 27 hours over 18 weeks. Considerable diversity in PNI outcomes made statistical comparisons problematic. Studies of cognitive-behavioral therapies were found to have reported the most success in impacting PNI-based measures, which were typically functional measures of the immune system, for example, cytokines.

CONCLUSION

Several issues related to research methodology are discussed. Most important, studies examining dose-response associations and resource allocation are needed to guide future research. A standardized panel of psychosocial instruments and biomarkers for PNI-based studies would enhance comparability of findings across studies when evaluating this body of research and assist with integrating psychosocial therapies into the standard of cancer care.
