Effects of an integrated yoga program in modulating psychological stress and radiation-induced genotoxic stress in breast cancer patients undergoing radiotherapy.

Effects of an integrated yoga program in modulating perceived stress levels, anxiety, as well as depression levels and radiation-induced DNA damage were studied in 68 breast cancer patients undergoing radiotherapy. Two psychological questionnaires—Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS)—and DNA damage assay were used in the study. There was a significant decrease in the HADS scores in the yoga intervention group, whereas the control group displayed an increase in these scores. Mean PSS was decreased in the yoga group, whereas the control group did not show any change pre- and postradiotherapy. Radiation-induced DNA damage was significantly elevated in both the yoga and control groups after radiotherapy, but the postradiotherapy DNA damage in the yoga group was slightly less when compared to the control group. An integrated approach of yoga intervention modulates the stress and DNA damage levels in breast cancer patients during radiotherapy.

Influence of yoga on mood states, distress, quality of life and immune outcomes in early stage breast cancer patients undergoing surgery.

Context: Breast cancer patients awaiting surgery experience heightened distress that could affect postoperative outcomes. Aims: The aim of our study was to evaluate the effects of yoga intervention on mood states, treatment-related symptoms, quality of life and immune outcomes in breast cancer patients undergoing surgery. Settings and Design: Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited for a randomized controlled trial comparing the effects of a yoga program with supportive therapy plus exercise rehabilitation on postoperative outcomes following surgery. Materials and Methods: Subjects were assessed prior to surgery and four weeks thereafter. Psychometric instruments were used to assess self-reported anxiety, depression, treatment-related distress and quality of life. Blood samples were collected for enumeration of T lymphocyte subsets (CD4 %, CD8 % and natural killer (NK) cell % counts) and serum immunoglobulins (IgG, IgA and IgM). Statistical Analysis Used: We used analysis of covariance to compare interventions postoperatively. Results: Sixty-nine patients contributed data to the current analysis (yoga n = 33, control n = 36). The results suggest a significant decrease in the state (P = 0.04) and trait (P = 0.004) of anxiety, depression (P = 0.01), symptom severity (P = 0.01), distress (P < 0.01) and improvement in quality of life (P = 0.01) in the yoga group as compared to the controls. There was also a significantly lesser decrease in CD 56% (P = 0.02) and lower levels of serum IgA (P = 0.001) in the yoga group as compared to controls following surgery. Conclusions: The results suggest possible benefits for yoga in reducing postoperative distress and preventing immune suppression following surgery.

Influence of yoga on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery

Context: Pre- and postoperative distress in breast cancer patients can cause complications and delay recovery from surgery. Objective: The aim of our study was to evaluate the effects of yoga intervention on postoperative outcomes and wound healing in early operable breast cancer patients undergoing surgery. Methods: Ninety-eight recently diagnosed stage II and III breast cancer patients were recruited in a randomized controlled trial comparing the effects of a yoga program with supportive therapy and exercise rehabilitation on postoperative outcomes and wound healing following surgery. Subjects were assessed at the baseline prior to surgery and four weeks later. Sociodemographic, clinical and investigative notes were ascertained in the beginning of the study. Blood samples were collected for estimation of plasma cytokines—soluble Interleukin (IL)-2 receptor (IL-2R), tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma. Postoperative outcomes such as the duration of hospital stay and drain retention, time of suture removal and postoperative complications were ascertained. We used independent samples t test and nonparametric Mann Whitney U tests to compare groups for postoperative outcomes and plasma cytokines. Regression analysis was done to determine predictors for postoperative outcomes. Results: Sixty-nine patients contributed data to the current analysis (yoga: n = 33, control: n = 36). The results suggest a significant decrease in the duration of hospital stay (P = 0.003), days of drain retention (P = 0.001) and days for suture removal (P = 0.03) in the yoga group as compared to the controls. There was also a significant decrease in plasma TNF alpha levels following surgery in the yoga group (P < 0.001), as compared to the controls. Regression analysis on postoperative outcomes showed that the yoga intervention affected the duration of drain retention and hospital stay as well as TNF alpha levels. Conclusion: The results suggest possible benefits of yoga in reducing postoperative complications in breast cancer patients.

Effects of an integrated Yoga Program on Self-reported Depression Scores in Breast Cancer Patients Undergoing Conventional Treatment: A Randomized Controlled Trial.

Aim: To compare the effects of yoga program with supportive therapy on self-reported symptoms of depression in breast cancer patients undergoing conventional treatment. Patients and Methods: Ninety-eight breast cancer patients with stage II and III disease from a cancer center were randomly assigned to receive yoga (n = 45) and supportive therapy (n = 53) over a 24-week period during which they underwent surgery followed by adjuvant radiotherapy (RT) or chemotherapy (CT) or both. The study stoppage criteria was progressive disease rendering the patient bedridden or any physical musculoskeletal injury resulting from intervention or less than 60% attendance to yoga intervention. Subjects underwent yoga intervention for 60 min daily with control group undergoing supportive therapy during their hospital visits. Becks Depression Inventory (BDI) and symptom checklist were assessed at baseline, after surgery, before, during, and after RT and six cycles of CT. We used analysis of covariance (intent-to-treat) to study the effects of intervention on depression scores and Pearson correlation analyses to evaluate the bivariate relationships. Results: A total of 69 participants contributed data to the current analysis (yoga, n = 33, and controls, n = 36). There was 29% attrition in this study. The results suggest an overall decrease in self-reported depression with time in both the groups. There was a significant decrease in depression scores in the yoga group as compared to controls following surgery, RT, and CT (P < 0.01). There was a positive correlation (P < 0.001) between depression scores with symptom severity and distress during surgery, RT, and CT. Conclusion: The results suggest possible antidepressant effects with yoga intervention in breast cancer patients undergoing conventional treatment.

Effect of Yoga on migraine: A comprehensive study using clinical profile and cardiac autonomic functions.

Context and Aims: Migraine is an episodic disabling headache requiring long-term management. Migraine management through Yoga therapy would reduce the medication cost with positive health benefits. Yoga has shown to improve the quality of life, reduce the episode of headache and medication. The aim of the present study was to evaluate the efficacy of Yoga as an adjuvant therapy in migraine patients by assessing clinical outcome and autonomic functions tests. Subjects and Methods: Migraine patients were randomly given either conventional care (n = 30) or Yoga with conventional care (n = 30). Yoga group received Yoga practice session for 5 days a week for 6 weeks along with conventional care. Clinical assessment (frequency, intensity of headache and headache impact) and autonomic function test were done at baseline and at the end of the intervention. Results: Yoga with conventional care and convention care groups showed significant improvement in clinical variables, but it was better with Yoga therapy. Improvement in the vagal tone along with reduced sympathetic activity was observed in patients with migraine receiving Yoga as adjuvant therapy. Conclusions: Intervention showed significant clinical improvement in both groups. Headache frequency and intensity were reduced more in Yoga with conventional care than the conventional care group alone. Furthermore, Yoga therapy enhanced the vagal tone and decreased the sympathetic drive, hence improving the cardiac autonomic balance. Thus, Yoga therapy can be effectively incorporated as an adjuvant therapy in migraine patients.

Comparison of lymphocyte apoptotic index and qualitative DNA damage in yoga practitioners and breast cancer patients: A pilot study.

Background: Yoga is found to be effective in reducing stress levels and radiation-induced DNA damage, and improving the quality of life, in breast cancer patients. The present study was aimed at comparing the apoptotic index (AI) and DNA damage of advanced yoga practitioners with those of breast cancer patients. Materials and Methods: This cross-sectional pilot study compared three groups (n = 9 each) of age-matched subjects viz. (1) Carcinoma breast patients in stage II or III undergoing radiation therapy after completing three cycles of chemotherapy; (2) Senior yoga practitioners who were practicing asanas, pranayama and meditation daily for more than 10 years; and (3) Normal healthy volunteers. Peripheral blood lymphocytes were isolated, and qualitative DNA damage (QDD) and AI were evaluated by single-cell gel electrophoresis assay. Approximately 500 cells were counted in each case. Number of cells that were normal, undergoing apoptosis, and with DNA damage were categorized and percentages were calculated. Results: Data being normally distributed, one-way analysis of variance (ANOVA) showed significant interaction between groups in AI (P = 0.016) and QDD (P = 0.045). On post-hoc analysis using Scheffe test, AI was significantly lower in non-yoga volunteers as compared with the breast cancer group (P = 0.019) and QDD was significantly lower in yoga practitioners when compared with non-yoga volunteers (P = 0.047). Conclusion: Cellular dysfunction (QDD) requires restorative mechanisms (AI) to restore the system to a balance. The results of this pilot study show trends, which indicate that in ill-health, there is inadequate restorative mechanisms (AI) although dysfunction (QDD) is high. Through regular practice of yoga, cellular dysfunction can be lowered, thus necessitating reduced restorative mechanisms. AI and QDD could also be useful indicators for predicting the three zones of health viz. disease, health, and positive health.

Clinical utility of gallium-68 PSMA PET/CT scan for prostate cancer

Background: Prostate cancer is biologically and clinically a heterogeneous disease that makes imaging evaluation challenging. One of the important challenges in this cancer is to detect recurrent disease. Biochemical response using Prostate Specific Antigen (PSA) and Imaging using several PET tracers have poor sensitivity and specificity. Therefore, we analyse the role of Ga68-PSMA (Prostate Specific Membrane Antigen) imaging in prostate cancer, which is a new PET tracer. Methods: In this study, we evaluated PET scans of 262 patients with diagnosis of prostate cancer. These patients were scanned using Ga68-PSMA for either staging or response evaluation. Results: 336 PSMA scans were performed. Ga68-PSMA scan resulted in the detection of extra-prostatic disease in 53.2% of cases when done at baseline before commencing any treatment. The sensitivity of Ga68-PSMA at baseline with histopathological diagnosis was 95% with 95% CI ranging from 86% to 98%. The positive predictive value was high at 98% with 95% CI ranging from 91% to 99%. In 26 (10%) patients who had surgical castration, Ga68-PSMA scan was able to detect disease progression / castration resistance in 100% of cases. The outcome of castration-resistant prostate cancer was compared with other cases where castration was not done. In those who did not undergo castration, there was a significantly better response by hormone therapy (p = 0.03) and radiotherapy (p = 0.01) on Ga68-PSMA. The sensitivity of Ga68-PSMA response with biochemical response was 66.7% with 95% CI ranging between 46 %- 82.7%. Ga68-PSMA response did not correlate with biochemical response. Conclusion: Ga68-PSMA has good sensitivity for diagnosis, staging, restaging, evaluation of therapy response and prognostication in prostate cancer.

Effect of long-term yoga practice on psychological outcomes in breast cancer survivors

Aim: Breast cancer has become a pandemic with an ever-increasing incidence. Although better diagnostics and treatment modalities have reduced mortality, a large number of survivors face cancer and treatment-related long-term symptoms. Many survivors are taking up yoga for improving the quality of life (QoL). The present study attempts to evaluate predictors of psychological states in breast cancer survivors with long-term yoga experience. Materials and Methods: A case–control study recruited early breast cancer survivors, 30–65 years, completing treatment > 6 months before recruitment, and grouped them based on prior yoga experience (BCY, n = 27) or naïve (BCN, n = 25). Demography, cancer history, diet, exercise habits, and yoga schedule were collected and tools to assess stress, anxiety, depression, general health, and QoL were administered. Multivariate linear regression was done to identify predictors of psychological variables. Results: BCY had significantly lower stress, anxiety, depression, better general health, and QoL (P < 0.001). Global QoL and trait anxiety were significantly predicted by Yoga practice; depression was predicted by yoga practice, annual income, and sleep quality; state anxiety was predicted by Yoga practice and income; and stress was predicted by Yoga practice and sleep quality. Conclusion: Results indicate that breast cancer survivors, doing yoga, have better psychological profiles and are able to deal with demanding situations better. The psycho-oncogenic model of cancer etiology suggests that a better psychological state in survival has the potential to improve prognosis and survival outcomes and Yoga may be a suitable practice for staying cancer-free for a longer time.

Integration of early specialist palliative care in cancer care: Survey of oncologists, oncology nurses, and patients

Introduction: Palliative care is usually delivered late in the course of illness trajectory. This precludes patients on active disease modifying treatment from receiving the benefit of palliative care intervention. A survey was conducted to know the opinion of oncologists, oncology nurses, and patients about the role of early specialist palliative care in cancer. Methods: A nonrandomized descriptive cross-sectional study was conducted at a tertiary cancer care center in India. Thirty oncologists, sixty oncology nurses, and sixty patients were surveyed. Results: Improvement in symptom control was appreciated by oncologists, oncology nurses, and patients with respect to pain (Z = −4.10, P = 0.001), (Z = −5.84, P = 0.001), (Z = −6.20, P = 0.001); nausea and vomiting (Z = −3.75, P = 0.001), (Z = −5.3, P = 0.001), (Z = −5.1, P = 0.001); constipation (Z = −3.29, P = 0.001), (Z = −4.96, P = 0.001), (Z = −4.49, P = 0.001); breathlessness (Z = −3.57, P = 0.001), (Z = −5.03, P = 0.001), (Z = −4.99, P = 0.001); and restlessness (Z = −3.68, P = 0.001), (Z = −5.23, P = 0.001), (Z = −3.22, P = 0.001). Improvement in end-of-life care management was appreciated by oncologists and oncology nurses with respect to communication of prognosis (Z = −4.04, P = 0.001), (Z = −5.20, P = 0.001); discussion on limitation of life-sustaining treatment (Z = −3.68, P = 0.001), (Z = −4.53, P = 0.001); end-of-life symptom management (Z = −4.17, P = 0.001), (Z = −4.59, P = 0.001); perimortem care (Z = −3.86, P = 0.001), (Z = −4.80, P = 0.001); and bereavement support (Z = −3-80, P = 0.001), (Z = −4.95, P = 0.001). Improvement in health-related communication was appreciated by oncologists, oncology nurses, and patients with respect to communicating health related information in a sensitive manner (Z = −3.74, P = 0.001), (Z = −5.47, P = 0.001), (Z = −6.12, P = 0.001); conducting family meeting (Z = −3.12, P = 0.002), (Z = −4.60, P = 0.001), (Z = −5.90, P = 0.001); discussing goals of care (Z = −3.43, P = 0.001), (Z = −5.49, P = 0.001), (Z = −5.61, P = 0.001); maintaining hope (Z = −3.22, P = 0.001), (Z = −4.85, P = 0.001), (Z = −5.61, P = 0.001); and resolution of conflict (Z = −3.56, P = 0.001), (Z = −5.29, P = 0.001), (Z = −5.28, P = 0.001). Patients appreciated improvement in continuity of care with respect to discharge planning (Z = −6.12, P = 0.001), optimal supply of essential symptom control medications on discharge (Z = −6.32, P = 0.001), follow-up plan (Z = −6.40, P = 0.001), after hours telephonic support (Z = −6.31, P = 0.001), and preferred place of care (Z = −6.28, P = 0.001). Conclusion: Oncologists, oncology nurses, and patients felt that integration of early specialist palliative care in cancer improves symptom control, end-of-life care, health-related communication, and continuity of care. The perceptions of benefit of the palliative care intervention in the components surveyed, differed among the three groups.

Pilot testing of triage coding system in Home-based palliative care using edmonton symptom assessment scale

Introduction: Home-based palliative care is an essential model of palliative care that aims to provide continuity of care at patients own home in an effective and timely manner. This study was a pilot test of triage coding system in home-based palliative care using Edmonton Symptom Assessment System (ESAS) scale. Methods: Objective of the study was to evaluate if the triage coding system in home-based palliative care: (a) Facilitated timely intervention, (b) improved symptom control, and (c) avoided hospital deaths. Homecare services were coded as high (Group 1 - ESAS scores ≥7), medium (Group 2 - ESAS scores 4–6), and low (Group 3 - ESAS scores 0–3) priority based on ESAS scores. In high priority group, patients received home visit in 0–3 working days; medium priority group, patients received home visit in 0–10 working days; and low priority group, patients received home visit in 0–15 working days. The triage duration of home visit was arbitrarily decided based on the previous retrospective audit and consensus of the experts involved in prioritization and triaging in home care. Results: “High priority” patients were visited in 2.63 ± 0.75 days; “medium priority” patients were visited in 7.00 ± 1.5 days, and “low priority” patients were visited in 10.54 ± 2.7 days. High and medium priority groups had a statistically significant improvement in most of the ESAS symptoms following palliative home care intervention. Intergroup comparison showed that improvement in symptoms was the highest in high priority group compared to medium and low priority group. There was an 8.5% increase in home and hospice deaths following the introduction of triage coding system. There was a significant decrease in deaths in the hospital in Group 1 (6.3%) (χ2 = 27.3, P < 0.001) compared to Group 2 (28.6%) and Group 3 (15.4%). Group 2 had more hospital deaths. Interval duration from triaging to first intervention was a significant predictor of survival with odds ratio 0.75 indicating that time taken for intervention from triaging was more significantly affecting survival than group triaging. Conclusion: Pilot study of testing triaging coding system in home-based palliative care showed, triage coding system: (a) Facilitated early palliative home care intervention, (b) improved symptom control, (c) decreased hospital deaths, predominantly in high priority group, and (d) time taken for intervention from triaging was a significant predictor of survival.
