Research suggests that stress‐reduction programs tailored to the cancer setting help patients cope with the effects of treatment and improve their quality of life. Yoga, an ancient Eastern science, incorporates stress‐reduction techniques that include regulated breathing, visual imagery, and meditation as well as various postures. The authors examined the effects of the Tibetan yoga (TY) practices of Tsa lung and Trul khor, which incorporate controlled breathing and visualization, mindfulness techniques, and low‐impact postures in patients with lymphoma.

PURPOSE Alternatives to axillary lymph node dissection (ALND) are being developed amid controversy surrounding the therapeutic benefit and overall utility of this routine surgical procedure. Although potential negative side effects associated with ALND are known, we set out to examine whether these side effects contribute significantly to patient reports of quality of life and mental health. PATIENTS AND METHODS We surveyed 222 women who had received an ALND as part of breast cancer surgery. All women underwent a physical therapy assessment of range of arm/shoulder motion and completed the Modified Post-operative Pain Questionnaire, the Pain Disability Index, the McGill Pain Questionnaire (short form), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and the Mental Health Inventory. RESULTS Seventy-two percent of the women experienced arm/shoulder pain, weakness, or numbness in the week before the interview, and range of motion of the affected arm/shoulder was impaired in 73% of the women. Severity of pain was reported to be low to moderate, and younger patients experienced greater pain than older patients. Pain severity correlated positively with the number of lymph nodes removed and receipt of chemotherapy and was not significantly related to length of time since surgery or receipt of radiation therapy. Generally high levels of cancer-specific quality of life and mental health were reported. Quality of life was significantly predicted by the McGill Pain Questionnaire, and mental health was significantly predicted by the Pain Disability Index and the physical therapy assessment. CONCLUSION Surgery-related symptoms after ALND persist for a majority of women with breast cancer and are not significantly related to time since surgery or receipt of radiation therapy. These symptoms and associated disability are significantly predictive of cancer-specific quality of life and mental health.

PURPOSE To examine the attitudes and practices of oncologists in disclosure of unfavorable medical information to cancer patients. METHODS A questionnaire was administered to a group of physicians who attended the 1999 Annual Meeting of the American Society of Clinical Oncology. The questionnaire assessed demographic and practice-related information and the frequency of patient encounters in which unfavorable cancer-related information was disclosed. Participants were also asked about difficulties they had when approaching stressful discussions and communication strategies used in giving unfavorable information. RESULTS The questionnaire was completed by 167 oncologists. Sixty-four percent were medical oncologists. Thirty-eight percent practiced in North America, 26% practiced in Europe, 13% practiced in South America, and 13% practiced in Asia. Participants gave bad news to patients an average of 35 times per month. Discussing no further curative treatment and hospice was reported as most difficult. In disclosing the cancer diagnosis and prognosis, physicians from Western countries were less likely to withhold unfavorable information from the patient at the familys request, avoid the discussion entirely, use euphemisms, and give treatments known not to be effective so as not to destroy hope than physicians from other countries. There was significant variability in opinions regarding the best time to discuss resuscitation, with 18% of respondents believing that it should be done close to the end of life. CONCLUSION There was significant variability in how physicians approach information disclosure to cancer patients. Factors such as geographical region and cultural and family variables may be important influences in this process.

Control and intrusive memories as possible determinants of chronic stress

Andrew Baum; Lorenzo Cohen; Martica Hall

&NA; Amidst confusion about the nature and usefulness of the stress construct and distinctions between acute and chronic stress, research has begun to identify mechanisms by which stress affects health and by which stress can persist beyond the physical presence of the stressor. In addition, research has begun to identify reasons for selective vulnerability to chronic stress. One of the possible reasons for chronic stress following traumatic events is the disorganizing effect of loss of control and violation of expectations for regulating aspects of ones life normally under control. Data from a longitudinal study of chronic stress at Three Mile Island in the wake of the nuclear accident there suggest that loss of control and frequent experience of intrusive memories about the accident and its aftermath were related to persistent stress responding several years after the accident. The relationships between stress responding and conditioning and consolidation of stressful memories are considered as a basis for persistent intrusive memories and chronic stress.

The mechanisms of stress-related immune alterations have not been fully elucidated. Cell-mediated immune responses as well as antibody and certain cytokines are reported as being suppressed during times of high stress. However, the role of suppression vs dysregulation has not been established in human stress models. The effect of exam stress on regulatory cytokines in 16 healthy medical students was assessed by measuring type-1 (IFN-gamma) and type-2 (IL-10) cytokines from 72-h PHA/PMA-stimulated PBMC 4 weeks before and 48 h after exams. Results demonstrated decreased IFN-gamma accompanied by increased IL-10 during exam stress that resulted in a decreased IFN-gamma:IL-10 ratio. There was a significant correlation between the cytokine response to PHA/PMA and number and subjective adjustment to daily hassles. Additionally, students who reported greater levels of loneliness also reported greater numbers of and poorer subjective adjustment to hassles. The differences were consistent in both males and females but did not correlate with AM cortisol levels. Additionally, when individuals were grouped into high vs low preexam hassle levels, the type-1/type-2 shift in the IFN-gamma:IL-10 ratio occurred in the low hassles group only. These data suggest that psychologically stressful situations shift type-1/type-2 cytokine balance toward type-2 and result in an immune dysregulation rather than overall immunosuppression. This may partially explain the increased incidence of type-2-mediated conditions such as increased viral infections, latent viral expression, allergic/asthmatic reactions, and autoimmunity reported during periods of high stress.

BackgroundThe various surgical procedures for early-stage breast cancer are equivalent in terms of survival. Therefore, other factors, such as the procedures’ effect on psychosocial adjustment and quality of life (QOL), take on great importance. The aim of the current study was to prospectively examine the short- and long-term effects of mastectomy with reconstruction, mastectomy without reconstruction, and breast conservation therapy on aspects of psychosocial adjustment and QOL in a sample of 258 women with breast cancer.MethodsParticipants completed questionnaires before surgery and then again 1, 6, 12, and 24 months after surgery. Questionnaires assessed depressive symptoms, anxiety, body image, sexual functioning, and QOL.ResultsAdjustment patterns differed throughout the 2-year period after surgery. Some short-term changes in adjustment (less anxiety, less overall body satisfaction) were similar across surgery groups, whereas others (satisfaction with chest appearance, QOL in physical health domain) were higher for women who had breast conservation therapy. However, women who had mastectomy with reconstruction reported greater satisfaction with their abdominal area. During the long-term follow-up period (6 months to 2 years after surgery), women in all three groups experienced marked improvements in psychosocial adjustment (depressive symptoms, satisfaction with chest appearance, sexual functioning) and QOL in physical and mental health domains. In fact, the level for most variables returned to baseline levels or higher.ConclusionsOverall, the general patterns of psychosocial adjustment and QOL are similar among the three surgery groups.

In recent years, the term integrative medicine has gained acceptance in medical academia. The Consortium of Academic Health Centers for Integrative Medicine defi nes this term as “the practice of medicine that reaffi rms the importance of the relationship between practitioner and patient, focuses on the whole person, is informed by evidence, and makes use of all appropriate therapeutic approaches, healthcare professionals, and disciplines to achieve optimal health and healing.” 1 Integrative oncology has been specifi cally described as both a science and a philosophy that focuses on the complex health of people with cancer and proposes an array of approaches to accompany the conventional therapies of surgery, chemotherapy, molecular therapeutics, and radiotherapy to facilitate health. 2 The SIO and its Medline -indexed journal ( Journal of the Society of Integrative Oncology ), founded by leading oncologists and oncology professionals from major cancer centers and organizations, promote quality research and appropriate application of useful, adjunctive complementary modalities T he Society for Integrative Oncology (SIO) is an international organization dedicated to encouraging scientifi c evaluation, dissemination of evidence-based information, and appropriate clinical integration of complementary therapies. Practice guidelines have been developed by the authors and endorsed by the Executive Committee of the SIO. Guidelines are a work in progress; they will be updated as needed and are available on the SIO Web site ().

PURPOSE Many cancer centers offer acupuncture services. To date, a comprehensive systematic review of acupuncture in cancer care has not been conducted. The purpose of this review was to evaluate the efficacy of acupuncture for symptom management in patients with cancer. METHODS Medline, Embase, CINAHL, Cochrane (all databases), Scopus, and PubMed were searched from inception through December 2011 for prospective randomized clinical trials (RCT) evaluating acupuncture for symptom management in cancer care. Only studies involving needle insertion into acupuncture points were included. No language limitations were applied. Studies were assessed for risk of bias (ROB) according to Cochrane criteria. Outcomes by symptom were designated as positive, negative, or unclear. RESULTS A total of 2,151 publications were screened. Of those, 41 RCTs involving eight symptoms (pain, nausea, hot flashes, fatigue, radiation-induced xerostomia, prolonged postoperative ileus, anxiety/mood disorders, and sleep disturbance) met all inclusion criteria. One positive trial of acupuncture for chemotherapy-induced nausea and vomiting had low ROB. Of the remaining studies, eight had unclear ROB (four positive, three negative, and one with unclear outcomes). Thirty-three studies had high ROB (19 positive, 11 negative, and three with both positive and negative outcomes depending on the symptom). CONCLUSION Acupuncture is an appropriate adjunctive treatment for chemotherapy-induced nausea/vomiting, but additional studies are needed. For other symptoms, efficacy remains undetermined owing to high ROB among studies. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.

Carl de Moor; Janet Sterner; Martica Hall; Carla L. Warneke; Zunera Gilani; Robert J. Amato; Lorenzo Cohen

Forty-two patients with metastatic renal cell carcinoma who were participating in a Phase II clinical trial were randomly assigned to an expressive writing (EW) or neutral writing (NW) group. Patients in the EW group wrote about their cancer, and patients in the NW group wrote about health behaviors. No statistically significant group differences were found in symptoms of distress, perceived stress, or mood disturbance, except for the Vigor subscale of the Profile of Mood States. However, patients in the EW group reported significantly less sleep disturbance, better sleep quality and sleep duration, and less daytime dysfunction compared with patients in the NW group. The results suggest that EW may have sleep-related health benefits in terminally ill cancer patients.
