Over one-third of Americans use complementary and alternative medicine (CAM). The prevalence among cancer patients may even be higher. Complementary therapies may reduce possible symptom burdens caused by conventional cancer treatments. Integrating CAM therapies has become more common and more accepted in clinical oncology. However, little research is available on beneficial CAM therapies for radiation therapy patients. This article reviews potential CAM therapies that have been shown to be effective in decreasing the symptom burden related to radiation therapy treatments and includes clinical observations from CAM practitioners in a comprehensive cancer center.

The purpose of this survey was to examine patient-doctor communication about the use of complementary and alternative medicine (CAM) by adult patients with cancer and compare patients' satisfaction with the consultation between patients who had and those who had not discussed the use of CAM with their doctors. Oncologists from three hospitals screened patients for eligibility. Eligible patients were mailed a letter of invitation with a questionnaire (N = 1,323). Three hundred eighty-one questionnaires were returned. Sixty-five percent of cancer patients used at least one form of CAM. Use of CAM was not discussed with the oncologist by 55% of respondents using biologically based CAM and by 80% of those using non-biologically based CAM since the diagnosis of cancer. Patients who discussed the use of biologic CAM with their oncologists were more satisfied with the consultation than those who had not (p = .027), whereas there were no significant differences between patients who discussed or did not discuss use of non-biologically based CAM (p = .102). A substantial proportion of cancer patients do not discuss the use of CAM with their oncologists. It is important to improve patient-doctor communication about the use of CAM to increase patients' satisfaction with the oncology consultation.

This study examined the effects of yoga on quality of life (QOL) and psychosocial outcomes in women with breast cancer undergoing radiotherapy. Sixty-one women were randomly assigned to either a yoga or a wait-list group. Yoga classes were taught biweekly during the 6 weeks of radiotherapy. Participants completed measures of QOL, fatigue, benefit finding (finding meaning in the cancer experience), intrusive thoughts, sleep disturbances, depressive symptoms, and anxiety before radiotherapy and then again 1 week, 1 month, and 3 months after the end of radiotherapy. General linear model analyses revealed that compared to the control group, the yoga group reported significantly better general health perception (p = .005) and physical functioning scores (p = .04) 1 week postradiotherapy; higher levels of intrusive thoughts 1 month postradiotherapy (p = .01); and greater benefit finding 3 months postradiotherapy (p = .01). There were no other group differences in other QOL subscales for fatigue, depression, or sleep scores. Exploratory analyses indicated that intrusive thoughts 1 month after radiotherapy were significantly positively correlated with benefit finding 3 months after radiotherapy (r = .36, p = .011). Our results indicated that the yoga program was associated with statistically and clinically significant improvements in aspects of QOL.

Current evidence indicates that acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) can provide sustained benefit for established radiation-induced xerostomia (RIX) symptoms. This is further being evaluated by comparing it with standard treatment (pilocarpine) in a randomized controlled trial. This report studies the potential effectiveness of xerostomia prevention using ALTENS delivered concomitantly with radiotherapy administered to head and neck cancer patients. Sixty patients were randomized to either the treatment group (n = 30) that received ALTENS daily with radiotherapy or the control group (n = 26) that had standard mouth care only. Stimulated and basal unstimulated whole saliva production (WSP) plus RIX symptoms visual analogue score (RIXVAS) were assessed at specific time points. Generalized linear models and generalized estimating equations were used for analysis. RIXVAS at 3 months follow-up after therapy completion was used as the primary study endpoint. The mean RIXVAS for the ALTENS intervention at 3 months was 39.8, which was not significantly different from the control arm value of 40.5. There were no statistically significant differences between the two groups for their mean RIXVAS and WSP at all assessment time points. In conclusion, there was no significant difference in mean WSP and RIXVAS between the two groups, so ALTENS is not recommended as a prophylactic intervention.

There are important safety concerns associated with dietary supplements and foods rich in phytoestrogens, especially for breast cancer patients with hormone-sensitive disease. However, no consensus has been reached concerning specific dietary items that should be avoided, and safe levels of potentially problematic foods have yet to be determined. Excellent qualitative reviews of phytoestrogens and breast cancer have been published. These list agents that contain phytoestrogens and offer general cautions. Quantitative reviews, however, are needed but not yet available. Here we review quantitative data on phytoestrogens, their interaction with estrogen receptors, their bioavailability and pharmacokinetics, and their effects on breast cancer cells and animal models. We also note foods and botanicals with substances that interact with estrogen receptors and discuss the phytoestrogens they contain. Based on current evidence, we propose recommendations for advising breast cancer patients, which may also serve as a basis for the development of clinical practice guidelines.

The purpose of this article is to share the lessons learned in forming an interdisciplinary team that implements a team science approach to integrative medicine (IM) research. The disciplines of nursing, statistics, and engineering, along with consultants and a reflexology practitioner, formed this university-based team to conceptualize and develop a prototype robotic device for reflexology for breast cancer patients. The nurse investigator contributed the intervention background and access to the population; the statistician guided the team thinking on factors that needed to be controlled for; the engineers provided the expertise in device design and development; consultants facilitated the team's thinking in new directions; and the reflexology practitioner prescribed the protocol. We discuss the contributions and achievements of each discipline, as well as the challenges, and share the team experiences with the intent to help guide the formation of new IM teams that promote a conducive atmosphere for carrying out cutting-edge IM research and advancing the science.

The purpose of this phase I dose-finding randomized controlled trial was to evaluate the safe and effective dose of isoflavones to be used in future clinical trials for prostate cancer prevention. Forty-five eligible men were supplemented with 40, 60, and 80 mg of purified isoflavones or no supplement from biopsy to prostatectomy. Compliance with the study agent, toxicity, and changes in plasma isoflavones, serum steroid hormones, prostate-specific antigen (PSA), and tissue Ki-67 were analyzed from baseline to completion of the study. Forty-four subjects completed the study with a duration of intervention of 30 (+/- 3) days. We observed significant increases in plasma isoflavones with treatment for all doses compared with controls without producing any toxicity. Significant increases in serum total estradiol were observed in the 40 and 60 mg isoflavone-treated arms. However, a significant increase in serum free testosterone was observed in the 60 mg isoflavone-treated arm. Changes in serum sex hormone-binding globulin, PSA, and percentage of tissue Ki-67 were not statistically significant with treatment for this sample size and duration of intervention. Our results identify a safe dose of purified isoflavones for future clinical trials and establish the need for further definitive, well-powered trials to examine the role of isoflavones in prostate carcinogenesis.

Cancer-induced cachexia (CIC) is a paraneoplastic syndrome that may account for up to 20% of deaths in cancer patients. Cachexia includes distinct metabolic changes that are the result of an acute-phase response (APR) mounted by the host as a reaction to tumor cells. These changes include increased muscle proteolysis, increased fat lipolysis, and increased hepatic production of acute-phase proteins such as C-reactive protein and fibrinogen. This APR pathogenesis is an important consideration in trying to treat cachectic patients as most therapies do not target the APR and its subsequent metabolic effects. Although there is currently no cure for CIC, the oncologist frequently encounters cachectic patients in practice, and evidence-based management is needed. We review the current data for assessment of starvation and cachexia, providing guidelines for management that include serum markers and functional assessment. In addition, a review of current therapies is provided, including hypercaloric feeding and nutritional intervention to address starvation, as well as data on appetite stimulants such as corticosteroids and megestrol acetate. Experimental therapies are also discussed, including nonsteroidal antiinflammatory drugs, tumor necrosis factor alpha antagonists, tetrahydrocannabinol, growth hormone, ghrelin, oxandrolone, and omega-3 fatty acids.

With the survival rates for childhood cancer growing, studies point to both the challenges and possible opportunities for personal growth that children with cancer may experience throughout their life journey. Examined in this review, research on the spirituality of childhood cancer survivors has provided insight into their overall spiritual journeys, their strategies to promote well-being, and the dynamics of hope and meaning within their lives. In an area that is in the early stages of research, the qualitative and exploratory research of the spirituality of childhood cancer survivors also contributes to the generation of future hypotheses. Finally, future research in this area should provide us with an enhanced understanding of spiritual paradigms that will assist us in making provisions for optimal support of children and their families.

In Europe, patients with colorectal carcinoma (CRC) frequently receive mistletoe extracts to improve quality of life and survival. This study was designed to evaluate supportive treatment with mistletoe extract Iscador (ISC) in nonmetastatic CRC patients under routine clinical conditions and to create well-founded hypotheses for future prospective clinical studies. The design of a multicenter, controlled, retrospective, observational cohort study with parallel groups met the Good Epidemiological Practice rules. Anonymous unselected standardized data from eligible patients with surgically treated stage I-III CRC and adjuvant therapy (AT) or conventional aftercare were included. End points were adjuvant therapy-related adverse reactions (AT-ADRs), symptoms, and disease-free survival (DFS). The results were adjusted for confounder effects. Eight hundred four (429 ISC vs 375 control) CRC patients from 26 centers were observed for a median of 58 versus 51 months; the median ISC therapy lasted 52 months. ISC patients showed fewer AT-ADRs (19% vs 48%, p < .001) and fewer persisting symptoms (p < .001). The DFS hazard ratio of 0.60 (p = .013) suggests a survival benefit in ISC patients versus controls. ISC was well tolerated without life-threatening ADRs, drug interactions, or tumor enhancement. These results suggest a beneficial effect of supportive care ISC therapy within AT protocols and long-term ISC treatment in stage I-III CRC patients, particularly improvement in AT-ADRs and symptoms and possible extension of DFS.
