A Randomized Controlled Trial of Tong Len Meditation Practice in Cancer Patients: Evaluation of a Distant Psychological Healing Effect.

CONTEXT: Tong Len meditation is an important therapeutic tool in the Tibetan medicine, and it can be used for self-healing and/or to heal others. Currently, in the West, there is no scientific study concerning the efficacy of a Tong Len distant healing effect on psychological disorders in cancer patients. OBJECTIVES: To evaluate a distant healing effect of Tong Len meditation on stress, anxiety, depression, fatigue, and self-perceived quality of life in cancer patients. These psychological objectives were chosen as a consequence of the limited scientific literature of present day. DESIGN: We performed a double-blind randomized controlled trial on 103 cancer patients with tumors. Overall, 12 meditators used Tong Len in aid of 52 patients randomly selected as experimental group, while the remaining 51 patients constituted the control group. Patients and meditators did not know each other. All patients completed profile of mood states (POMS) and European Quality of Life-5 dimensions (EQ-5D) questionnaires before treatment (T0), after two (T1) and three months of treatment (T2), and one month after treatment cessation (T3). RESULTS: With regard to the parameters related to depression, a statistically significant improvement (P = .003) was observed in the treatment group compared to controls. On the other hand, the vigor/activity parameter saw significant improvements in the control group (P = .009). Both groups exhibited significant improvements in the other factors assessed in the POMS and EQ-5D questionnaires. CONCLUSIONS: This study did not provide sufficient evidence supporting an efficacy of Tong Len meditation in distant psychological healing as compared to a control condition. The research highlighted some psychological improvements through Tong Len distant meditation in a group of patients unknown to meditators. Therefore, the enhancement detected in most parameters in both treatment and control groups raises interest on in-depth analysis and evaluation of distant meditation on cancer patients to mitigate psychological problems caused by the disease.

Central nervous system metastases in HER-2 positive metastatic breast cancer patients treated with trastuzumab: incidence, survival, and risk factors.

BACKGROUND: A higher incidence of central nervous system (CNS) metastases in HER-2-positive metastatic breast cancer (MBC) has recently been reported. MATERIALS AND METHODS: Aims of this observational study were to evaluate the incidence of CNS metastases in HER-2-positive MBC patients, to define the outcome of patients with CNS metastases, and to identify the risk factors for CNS relapse. RESULTS: Between April 1999 and June 2005 we treated 122 consecutive HER-2-positive MBC patients with chemotherapy and trastuzumab. At a median follow-up of 28 months from the occurrence of metastatic disease, 43 patients (35.2%) developed CNS metastases. The median time to death from the diagnosis of CNS metastases was 23.46 months. At multivariate analysis we found that only premenopausal status at diagnosis of breast cancer and visceral metastases as the dominant site at relapse were significantly associated with a higher risk for CNS metastases. CONCLUSION: The CNS metastasis incidence is very high in HER-2-positive MBC, but the survival after CNS relapse in these patients is longer than in patients unselected for HER-2 status, because of the better control of extracranial disease obtained by trastuzumab. The identified risk factors for CNS relapse could allow us to select a subgroup of HER-2-positive MBC patients as candidates for active surveillance for CNS progression (by computed tomography or magnetic resonance imaging) and/or as candidates for accrual in trials of prevention of CNS relapse.
