Cheli S, Caligiani L, Martella F, De Bartolo P, Mancini F, Fioretto L. Mindfulness and metacognition in facing with fear of recurrence: A proof-of-concept study with breast-cancer women. Psychooncology 2019 Mar;28(3):600-606 PMID 30656783
OBJECTIVE: Fear of recurrence is a crucial issue in cancer care. On the one hand, the increase of cancer-survival rates and complexity of care is exposing patients to this type of fear. On the other hand, it is a distressing and recurrent psychosocial risk that affects quality of life and adherence to follow-up. Patients should have access to targeted psychological interventions aimed at reducing or preventing fear of recurrence. This mixed-methods pilot study reports the preliminary results of a novel mindfulness- and metacognition-based intervention specifically targeting fear of recurrence. METHODS: The study was composed of an individual (n = 76) and a group (n = 38) intervention, both lasting 8 weeks, that were evaluated through a preassessment and postassessment and a 1-month follow-up. We enrolled women recovering from breast cancer (n = 114) in follow-up care, with significant psychosocial distress. Patients with more severe psychopathology were assigned to the individual treatment, whereas the less severe ones were assigned to the group treatment. We explored the distress and the fear of recurrence through standardized measures and in-depth qualitative interviews. RESULTS: Results showed that depressive, anxious, and post-traumatic symptoms were reduced significantly in the entire sample. Patients reported a significant reduction of fear of recurrence, which was described in terms of loss of control, increase of uncertainty, and decrease of metacognitive and interpersonal skills. CONCLUSIONS: Although further studies are needed, these findings provide preliminary proof-of-concept results for the potential of integrated mindfulness- and metacognition-based interventions to reduce fear of recurrence in cancer patients.

BACKGROUND: Traditional Chinese Medicine (TCM) therapies have been combined with chemotherapy for preventing Recurrence and metastasis in postoperative II to IIIA non-small-cell lung cancer (NSCLC) and the associated better disease-free survival (DFS), but its effects remain elusive. The purpose of this review is to assess the efficacy of TCM therapies as a treatment for postoperative II to IIIA NSCLC. METHODS AND ANALYSIS: Seventh databases will be searched for relevant studies from inception to the present date. We will include randomized controlled trials assessing TCM therapies combined with chemotherapy for preventing Recurrence and metastasis in postoperative II to IIIA NSCLC. The methodological qualities, including the risk of bias, will be evaluated using the Cochrane risk of bias assessment tool, while confidence in the cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. ETHICS AND DISSEMINATION: Ethical approval is not required, as this study is based on the review of published research. This review will be published in a peer-reviewed journal and disseminated both electronically and in print. PROSPERO REGISTRATION NUMBER: The protocol for this systematic review has been registered on PROSPERO under the number CRD42019116594.
Coutino-Escamilla L, Pina-Pozas M, Tobias Garces A, Gamboa-Loira B, Lopez-Carrillo L. Non-pharmacological therapies for depressive symptoms in breast cancer patients: Systematic review and meta-analysis of randomized clinical trials. Breast 2019 Apr;44:135-143 PMID 30776733
OBJECTIVE: Depressive symptoms are common comorbidities among breast cancer (BC) patients. Non-pharmacological therapies (NPTs) such as exercise and psychotherapy may reduce depressive symptoms; however, the evidence is inconclusive. The objective of this study is to evaluate if NPTs reduce depressive symptoms among BC patients. METHODS: A systematic review and meta-analysis of randomized clinical trials (RCTs) of NPTs for BC patients were performed. A literature search was conducted from eight databases in English, Portuguese and Spanish from 2006 to 2017. Inclusion criteria were: RCTs that evaluated depressive symptoms as a primary or secondary outcome that did not include pharmacological interventions and did include a non-intervened control group, with at least 30 participants in non-terminal BC stage with no current psychiatric illness. A meta-analysis for each NPT was performed with DerSimonian and Laird's method for the random effects model. Sensitivity analyses were conducted. Heterogeneity and publication bias were assessed. RESULTS: A total of 41 eligible RCTs were identified. Overall, NPTs significantly reduced depressive symptoms (Summary standardized mean difference (SMD)=-0.516; 95%CI: -0.814, -0.218; I(2)=96.2). Of the types of NPTs, psychotherapy significantly reduced depressive symptoms (Summary SMD=-0.819; 95% CI: -1.608, -0.030; I(2)=91.53). A significant difference emerged for Mindfulness (Summary SMD=-0.241; 95% CI: -0.412, -0.070; I(2)=28.6%) and yoga (Summary SMD=-0.305; 95% CI: -0.602, -0.007; I(2)=41.0%) when the heterogeneity was reduced. No evidence of publication bias was observed. CONCLUSIONS: Psychotherapy and mind-body therapies may reduce depressive symptoms in women with BC. Laughter and couples therapy warrant attention in future studies.
Donovan E, Martin SR, Seidman LC, Zeltzer LK, Cousineau TM, Payne LA, et al. A Mobile-Based Mindfulness and Social Support Program for Adolescents and Young Adults With Sarcoma: Development and Pilot Testing. JMIR Mhealth Uhealth 2019 Mar 18;7(3):e10921 PMID 30882352
BACKGROUND: Approximately 70,000 adolescents and young adults (AYA) are diagnosed with cancer each year in the United States. Sarcomas carry a particularly high symptom burden and are some of the most common cancers among AYA. Recent work has documented significant levels of unmet needs among AYA with cancer, particularly the need for psychosocial support. Mobile technology may be a cost-effective and efficient way to deliver a psychosocial intervention to AYA with cancer and cancer survivors. OBJECTIVE: The two aims of this study were to (1) develop a pilot version of a mobile-based mindfulness and social support program and (2) evaluate program usage and acceptability. An exploratory aim was to examine change in psychosocial outcomes. METHODS: Thirty-seven AYA with sarcoma or sarcoma survivors, parents, and health care providers participated in the study. Semistructured interviews were conducted with 10 AYA, parents of five of the adolescents, and six health care providers. Themes from the interviews helped to inform the development of a mobile-based mindfulness pilot program and a companion Facebook-based social support group. Twenty AYA consented to participate in a single-arm pre-post evaluation of the program; 17 downloaded the app and joined the Facebook group. Seven of these participants had participated in the semistructured interviews. Six additional health care providers consented to participate in the evaluation stage. RESULTS: On average, participants completed 16.9 of the 28 unique sessions and used the mindfulness app for a mean 10.2 (SD 8.2) days during the 28-day evaluation period. The majority of participants (16/17) engaged in the social group and posted at least one reply to the moderator's prompts. The mean number of responses per person to the moderator of the social group was 15.2 of 31 (49%, range 0%-97%). Both AYA and health care providers responded positively to the Mindfulness for Resilience in Illness program and offered useful recommendations for improvements. Exploratory psychosocial analyses indicated there were no significant differences from pretest to posttest on measures of perceived social support, mindfulness, body image, or psychological functioning. CONCLUSIONS: This study offers preliminary support for the feasibility and acceptability of a mobile-based mindfulness and Facebook-based social support program for AYA with sarcoma. The feedback from AYA and health care providers will assist in creating a fully developed intervention.

Ghasemi F, Sarabi PZ, Athari SS, Esmaeilzadeh A. Therapeutics strategies against cancer stem cell in breast cancer. Int J Biochem Cell Biol 2019 Apr;109:76-81 PMID 30772480
Breast cancer is known as a most prevalent cancer and second deadly cancer, among women worldwide. Due to the high incidence rate of breast cancer and limitations of conventional therapy it seemed essential to look for new targets in cancer cells and directly target them such as target therapy on breast cancer stem cells. In this review we indicate some of therapeutic uses of cancer stem cells in breast cancer. Some strategies are targeting surface specific markers and activated signaling pathways in their microenvironment such as Notch, Hedgehog, Wnt/b-catenin, PI3K/Akt, NF-kB, BMP and TGF-beta and their maintenance and drug resistance, using various miRNAs, enhancement of CSCs apoptosis, differentiation therapy, blocking epithelial to mesenchymal transition and using different natural compounds. Recent studies have shown that cancer stem cells play major roles in target therapy on breast cancer. The new manipulation approaches of cancer stem cells can be used as target therapy of breast cancer that were highlighted for immunotherapy of cancer.
Glaser KM, McDaniel DC, Hess SM, Flores TF, Rokitka DA, Reid ME. Implementing an Integrative Survivorship Program at a Comprehensive Cancer Center: A Multimodal Approach to Life After Cancer. J Altern Complement Med 2019 Mar;25(S1):S106-S111 PMID 30870027
BACKGROUND: This article describes the development of an integrative survivorship program at an urban National Cancer Institute-designated comprehensive cancer center with three closely linked components: a Survivorship Clinic with dedicated staff, a network of Support Services including Wellness, and an Integrative Medicine Program. DEVELOPMENT: We first defined the parameters of survivorship care and developed a patient-centric model that determined the optimal timeframes for transitioning these patients from the oncology clinic to a centralized survivorship clinic. Survivorship care includes the development of a survivorship care plan (SCP) for each patient at their initial visit to the program. Quality-of-life assessments are used in real time to guide clinical decision making to referrals to supportive care services, including educational events, expert consultations, and treatment using integrative and complementary therapies, access to legal services, community resource information, and support group activities for cancer survivors and caregivers. Integrative therapies were added to support the needs of this new program, including recruiting a nutritionist and acupuncturist, and developing a yoga, mindfulness, and Reiki program. Population served: As of June 2018, 908 people have accessed our survivorship clinic, receiving a complete clinical assessment and SCP. Patients are routinely referred to support services based on the individual needs and ongoing symptoms from treatment. The majority of referrals are made to acupuncture, Healing Touch or Reiki, nutrition, psychosocial oncology, and yoga. CONCLUSIONS: Developing a successful integrative survivorship program requires some essential features, including institutional support, strong leadership, a clear vision of how the clinical program will function, a dedicated team that is willing to do what it takes to get the program off the ground, and clinical oncology champions to refer patients into the program. With the development of this program, this multimodal approach to patient-centric care is maintained throughout the spectrum of care, from diagnosis to survivorship.
Milbury K, Liao Z, Shannon V, Mallaiah S, Nagarathna R, Li Y, et al. Dyadic yoga program for patients undergoing thoracic radiotherapy and their family caregivers: Results of a pilot randomized controlled trial. Psychooncology 2019 Mar;28(3):615-621 PMID 30659739
OBJECTIVE: Thoracic radiotherapy (TRT) may result in toxicities that are associated with performance declines and poor quality of life (QOL) for patients and their family caregivers. The purpose of this randomized controlled trial was to establish feasibility and preliminary efficacy of a dyadic yoga (DY) intervention as a supportive care strategy. METHODS: Patients with stage I to III non-small cell lung or esophageal cancer undergoing TRT and their caregivers (N = 26 dyads) were randomized to a 15-session DY or a waitlist control (WLC) group. Prior to TRT and randomization, both groups completed measures of QOL (SF-36) and depressive symptoms (CES-D). Patients also completed the 6-minute walk test (6MWT). Dyads were reassessed on the last day of TRT and 3 months later. RESULTS: A priori feasibility criteria were met regarding consent (68%), adherence (80%), and retention (81%) rates. Controlling for relevant covariates, multilevel modeling analyses revealed significant clinical improvements for patients in the DY group compared with the WLC group for the 6MWT (means: DY = 473 m vs WLC = 397 m, d = 1.19) and SF-36 physical function (means: DY = 38.77 vs WLC = 30.88; d = .66) and social function (means: DY = 45.24 vs WLC = 39.09; d = .44) across the follow-up period. Caregivers in the DY group reported marginally clinically significant improvements in SF-36 vitality (means: DY = 53.05 vs WLC = 48.84; d = .39) and role performance (means: DY = 52.78 vs WLC = 48.59; d = .51) relative to those in the WLC group. CONCLUSIONS: This novel supportive care program appears to be feasible and beneficial for patients undergoing TRT and their caregivers. A larger efficacy trial with a more stringent control group is warranted.
Miller KR, Patel JN, Symanowski JT, Edelen CA, Walsh D. Acupuncture for Cancer Pain and Symptom Management in a Palliative Medicine Clinic. Am J Hosp Palliat Care 2019 Apr;36(4):326-332 PMID 30286611
OBJECTIVE:: Studies suggest acupuncture improves cancer-related symptoms; however, it is unclear whether patient characteristics predict pain response. This study determined acupuncture's effect on cancer-related pain and identified variables associated with pain response. METHODS:: A retrospective chart review included adult patients with cancer referred to palliative medicine and received acupuncture for pain management. Paired t tests compared differences in pain scores from pre- to postacupuncture. Clinically meaningful pain improvement was defined as >/=2-point reduction in pain score. Logistic regression was used to evaluate associations between patient characteristics and pain improvement. RESULTS:: One hundred seventy acupuncture treatments from 68 individual patients were studied. Significant reductions in mean pain scores were observed after the first treatment (-1.9 +/- 1.8; P < .001) and across all treatments (-1.7 +/- 1.9; P < .001). Multivariable analysis demonstrated clinically meaningful pain improvement with higher baseline pain scores (odds ratio [OR]: 1.79, 95% confidence interval [CI]: 1.44-2.22; P < .001) and stage III/IV disease (OR: 3.23, 95% CI: 1.11-9.40; P < .001). There were significant improvements in anxiety, depression, drowsiness, dyspnea, fatigue, nausea, and well-being after the first treatment and across all treatments ( P < .001). CONCLUSIONS:: Acupuncture improved cancer-related pain and other symptoms. Those with higher baseline pain scores and advanced disease were more likely to achieve significant pain reduction. Improved depression and fatigue were closely related to pain reduction. Further studies are needed to confirm pain response variables, establish durability, and develop a personalized approach to acupuncture.
Nissim R, Malfitano C, Coleman M, Rodin G, Elliott M. A Qualitative Study of a Compassion, Presence, and Resilience Training for Oncology Interprofessional Teams. J Holist Nurs 2019 Mar;37(1):30-44 PMID 29598225
The well-being of health care providers may be challenged by their work, with evidence that oncology health care providers are a high-risk group for burnout. The present qualitative pilot study evaluated a mindfulness-based group intervention, referred to as Compassion, Presence, and Resilience Training (CPR-T), for oncology interprofessional teams. The purpose of this study was to elucidate the subjective experience of oncology health care providers receiving CPR-T and their perceptions of its benefits, risks, or challenges. The CPR-T was delivered to providers from two oncology teams in a large cancer center in Canada. Ten of these providers participated in semistructured interviews 1 to 5 months after completing the CPR-T. The interview transcripts were coded using a thematic analysis strategy. Five benefits of the CPR-T were identified: learning to pause, acquiring a working definition of stress and self-care, becoming fully present, building self-compassion, and receiving organizational acknowledgment and recognition of stress. In addition, two participant-identified challenges were recognized: sharing vulnerability within interprofessional teams and committing to a sitting meditation practice. These findings demonstrate positive transformations as a result of the CPR-T, as well as important challenges, and have important implications for holistic health care practice in oncology. Further research is necessary to validate the findings of this explorative study.
Rajanahally S, Raheem O, Rogers M, Brisbane W, Ostrowski K, Lendvay T, et al. The relationship between cannabis and male infertility, sexual health, and neoplasm: a systematic review. Andrology 2019 Mar;7(2):139-147 PMID 30767424
BACKGROUND: In the United States of America (USA), cannabis is legal in 28 states for medical purposes and 8 states for recreational use. In 2016, the legal marijuana industry reached nearly $7 billion in sales in the USA alone. Although consumption continues to increase, the medical effects of marijuana remain understudied. Young males comprise the demographic most likely to consume cannabis, and these individuals will be most vulnerable to its short- and long-term consequences. OBJECTIVE: The purpose of this manuscript is to systematically review the available literature describing the effects of marijuana on male infertility, sexual health, and urologic neoplasms. MATERIALS AND METHODS: A comprehensive literature search was conducted using the Medline and Embase databases through May 2017. In vitro models, animal models, case series, case-control, and cohort designs were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was utilized to report results. RESULTS: After exclusions, 91 articles were synthesized for qualitative analysis. Of these manuscripts, 30 pertained to marijuana and male infertility, 36 discussed cannabis and male sexual health/hormones, and 25 explored the relationship between marijuana and urologic neoplasms. DISCUSSION: With respect to male factor fertility using semen parameters as a surrogate, cannabinoids likely play an inhibitory role. Data on marijuana and male sexual function are mixed but suggest that marijuana may enhance the subjective experience of sexual intercourse while potentially contributing to ED in a dose-dependent manner. Cannabis has been associated with both increased and decreased risk of malignancy depending upon the target organ. Marijuana exposure seems to be an independent risk factor for testis cancer, data on bladder cancer are conflicting, and the evidence on prostate cancer supports anti-neoplastic effects of cannabinoids. CONCLUSION: Studies of the effects of cannabis suggest impact on urologic health and disease. Prospective, long-term studies are necessary for further elucidation of these effects.
Toth KF, Adam D, Biro T, Olah A. Cannabinoid Signaling in the Skin: Therapeutic Potential of the "C(ut)annabinoid" System. Molecules 2019 Mar 6;24(5):10.3390/molecules24050918 PMID 30845666
The endocannabinoid system (ECS) has lately been proven to be an important, multifaceted homeostatic regulator, which influences a wide-variety of physiological processes all over the body. Its members, the endocannabinoids (eCBs; e.g., anandamide), the eCB-responsive receptors (e.g., CB(1), CB(2)), as well as the complex enzyme and transporter apparatus involved in the metabolism of the ligands were shown to be expressed in several tissues, including the skin. Although the best studied functions over the ECS are related to the central nervous system and to immune processes, experimental efforts over the last two decades have unambiguously confirmed that cutaneous cannabinoid ("c[ut]annabinoid") signaling is deeply involved in the maintenance of skin homeostasis, barrier formation and regeneration, and its dysregulation was implicated to contribute to several highly prevalent diseases and disorders, e.g., atopic dermatitis, psoriasis, scleroderma, acne, hair growth and pigmentation disorders, keratin diseases, various tumors, and itch. The current review aims to give an overview of the available skin-relevant endo- and phytocannabinoid literature with a special emphasis on the putative translational potential, and to highlight promising future research directions as well as existing challenges.
Wang YQ, Liu X, Jia Y, Xie J. Impact of breathing exercises in subjects with lung cancer undergoing surgical resection: A systematic review and meta-analysis. J Clin Nurs 2019 Mar;28(5-6):717-732 PMID 30357997
AIMS AND OBJECTIVES: To assess the effects of breathing exercises on postoperative pulmonary complications (PPCs), pulmonary function, 6-min walk distance (6MWD) and the length of hospital stay (LOS) in lung cancer patients undergoing lung surgery. BACKGROUND: Lung cancer patients undergoing lung resection have poor pulmonary function and multiple PPCs. Breathing exercises may improve these symptoms. DESIGN: Systematic literature review and meta-analysis were conducted. METHODS: All entries to the following databases were searched up until 20 December 2017: PubMed, EMBASE Ovid, the Cochrane Central Register of Randomized Controlled Trials, Web of Science, Wanfang, Weipu and Chinese National Knowledge Infrastructure databases. Only randomised controlled trials (RCTs) were included in the analysis. RESULTS: A total of sixteen articles including nine articles in Chinese language and seven articles in English met the inclusion criteria. Breathing exercises decreased PPCs, and in addition, the incidence of pneumonia and atelectasis in the postoperative subgroup was reduced. Predicted forced expiratory volume in 1 s (predicted FEV1 %), predicted forced vital capacity (predicted FVC%), FVC and FEV1 /FVC ratio had improved after breathing exercises, but the changes in FEV1 were not statistically significant. Furthermore, the LOS was significantly decreased, but no improvements were found in 6MWD. CONCLUSIONS: The results showed that breathing exercises could improve lung function, decrease the incidence of PPCs and LOS in a sample of lung cancer patients undergoing pulmonary surgery. RELEVANCE TO CLINICAL PRACTICE: The analysis suggests that breathing exercises should be considered as a respiratory rehabilitation programme for lung cancer patients undergoing lung surgery in clinical practice.
Weeks J. Musings on Patient Care and Polarization After JAMA Oncology's Erroneous Report That Complementary Medicine Kills. Explore (NY) 2019 Mar - Apr;15(2):82-87 PMID 30709782
Wode K, Henriksson R, Sharp L, Stoltenberg A, Hok Nordberg J. Cancer patients' use of complementary and alternative medicine in Sweden: a cross-sectional study. BMC Complement Altern Med 2019 Mar 13;19(1):62-019-2452-5 PMID 30866916
BACKGROUND: Access to and advice on Complementary and Alternative Medicine (CAM) are uncommon within Swedish conventional cancer care and little is known about cancer patients' own use of CAM. The aim of this cross-sectional study was to explore Swedish cancer patients patterns of CAM use, their experiences and preferences. METHODS: Questionnaires were distributed consecutively to 1297 cancer patients at a university hospital's out-patient oncology units. The response rate was 58% (n = 755). Descriptive statistics were used to analyze the survey data. A logistic regression model was used to investigate the association between CAM use and gender, age and level of education. Open-ended responses were analyzed, using qualitative content analysis. RESULTS: Lifetime CAM use was reported by 34% (n = 256), and 26% (n = 198) used CAM after cancer diagnosis. Being female, younger and having higher education predicted CAM use. Most commonly used methods were natural products including vitamins and minerals and relaxation. Main reasons for CAM use were improvement of physical, general and emotional wellbeing and increasing the body's ability to fight cancer. Satisfaction with CAM usage was generally high. Reported adverse effects were few and mild; 54% of users spent < 50 Euro a month on CAM. One third had discussed their CAM use with cancer care providers. More than half of all participants thought that cancer care providers should be able to discuss (58%) and to consider (54%) use of CAM modalities in cancer care. CONCLUSIONS: Despite limited access and advice within conventional cancer care, one fourth of Swedish cancer patients use CAM. The insufficient patient-provider dialogue diverges with most patients' wish for professional guidance in their decisions and integration of CAM modalities in conventional cancer care. Concurrent and multimodal CAM use implies challenges and possibilities for cancer care that need to be considered.
Xu Z, Zhang F, Zhu Y, Liu F, Chen X, Wei L, et al. Traditional Chinese medicine Ze-Qi-Tang formula inhibit growth of non-small-cell lung cancer cells through the p53 pathway. J Ethnopharmacol 2019 Apr 24;234:180-188 PMID 30660711
ETHNOPHARMACOLOGICAL RELEVANCE: Ze-Qi-Tang (ZQT), a classic Chinese herbal formula, has been for over thousand years used for the treatment of several respiratory ailments like cough, asthma, hydrothorax and lung cancer. AIM OF STUDY: Cumulative literature on ZQT herbal formula reveals that its several constituent components are potent inducer of apoptosis in different cancer cells. However, the activity of ZQT against non-small-cell-lung cancer (NSCLC) has not been previously examined. The aim of the study is to investigate the molecular mechanism of ZQT on NSCLC cells. MATERIALS AND METHODS: Cell growth were determined by CCK-8 and colony formation assay. Induction of cellular apoptosis or arrest of cell cycle were determined by flow cytometric analysis using annexin V/ propidium iodide, Hoechst 33342 or TUNEL staining method. In some assay p53 activity of NSCLC ( A549 and H460) cells were blocked with pifithrin-a, prior to treatment with ZQT. The level of expression of cell cycle and apoptosis related marker proteins were estimated by western blot. The anticancer activity of ZQT in vivo were monitored in nude mice that were induced with tumor by subcutaneous inoculation of A549 cells and then treated by ZQT(100mg/kg,200mg/kg,400mg/kg) gavaging for 30 days. Mice' body weight and tumor volume were measured weekly. The survival carve was recorded. Apoptosis from mice' tissue was observed by TUNEL assay. Pathological histology of liver, kidney and heart were detected by H&E staining, and its functions were tested by ELISA. RESULTS: Dose- and time-dependent inhibition of proliferation of NSCLC ( A549 and H460) cells by ZQT therapy along with induction of cell cycle arrest at G0G1 phase were observed. The arrest of cell cycle arrest and inhibition of cellular proliferation were associated with up regulation of p53 along with down regulation of Cyclin B1 and Cdk2 indicating a mitochondrial related induction of apoptosis with ZQT. A reversal of ZQT-induced apoptosis and G0G1 arrest was observed with pifithrin-a pretreatment. ZQT was also found to suppress the progression of tumor growth in mouse xenograft models and prolong survival. In addition, no hepato- or nephro- or cardio-toxicity with ZQT treatment were detected in mice. CONCLUSION: These findings suggest that the ZQT formula inhibits the growth of NSCLC cells and is a potential agent of complementary and alternative treatment for lung cancer.
