Positive effects of acupressure bands combined with relaxation music/instructions on patients most at risk for chemotherapy-induced nausea.

PURPOSE: Research by our group has shown that acupressure bands are efficacious in reducing chemotherapy-induced nausea (CIN) for breast cancer patients who expect nausea, and that their effectiveness in controlling CIN can largely be accounted for by patients' expectations of efficacy, i.e., a placebo effect. The present research examined if the effectiveness of acupressure bands could be enhanced by boosting patients' expectation of the bands' efficacy. METHODS: Two hundred forty-two chemotherapy-naïve patients with breast cancer who expected nausea were randomized. Arms 1 and 2 received acupressure bands, plus a relaxation MP3 and written handout that were either expectancy-enhancing (arm 1) or expectancy-neutral (arm 2). Arm 3 was the control without bands or MP3 and received standard care. All participants received guideline-specified antiemetics. RESULTS: Peak CIN for arms 1, 2, and 3 on a 1-7 scale was 3.52, 3.55, and 3.87, respectively (p = 0.46). Because no differences were observed between arms 1 and 2 (primary analysis), we combined these two arms (intervention) and compared them to controls for the following analyses. A significant interaction was found between intervention/control and receiving doxorubicin-based chemotherapy (yes/no) and pre-treatment anxiety (high/low). Intervention patients receiving doxorubicin had lower peak CIN than controls (3.62 vs. 4.38; p = 0.02). Similarly, intervention patients with high pre-treatment anxiety had a lower peak CIN than controls (3.62 vs. 4.62; p = 0.01). CONCLUSIONS: In breast cancer patients undergoing chemotherapy and having high CIN expectation, acupressure bands combined with a relaxation recording were effective in reducing CIN for patients who received doxorubicin or had high anxiety.

Buspirone for management of dyspnea in cancer patients receiving chemotherapy: a randomized placebo-controlled URCC CCOP study.

PURPOSE: Cancer-related dyspnea is a common, distressing, and difficult-to-manage symptom in cancer patients, resulting in diminished quality of life and poor prognosis. Buspirone, a non-benzodiazepine anxiolytic which does not suppress respiration and has proven efficacy in the treatment of generalized anxiety disorder, has been suggested to relieve the sensation of dyspnea in patients with COPD. The main objective of our study was to evaluate whether buspirone alleviates dyspnea in cancer patients. METHODS: We report on a randomized, placebo-controlled trial of 432 patients (mean age 64, female 51%, lung cancer 62%) from 16 participating Community Clinical Oncology Program (CCOP) sites with grade 2 or higher dyspnea, as assessed by the Modified Medical Research Council Dyspnea Scale. Dyspnea was assessed by the Oxygen Cost Diagram (OCD; higher scores are better) and anxiety by the state subscale of the State-Trait Anxiety Inventory (STAI-S; lower scores are better) at baseline and after the 4-week intervention (post-intervention). RESULTS: Mean scores from baseline to post-intervention for buspirone were OCD 8.7 to 9.0 and STAI-S 40.5 to 40.1 and for placebo were OCD 8.4 to 9.3 and STAI-S 40.9 to 38.6 with raw improvements over time on both measures being greater in the placebo group. Analysis of covariance (ANCOVA) controlling for baseline scores showed no statistically significant difference between groups for OCD (P = 0.052) or STAI-S (P = 0.062). CONCLUSION: Buspirone did not result in significant improvement in dyspnea or anxiety in cancer patients. Thus, buspirone should not be recommended as a pharmacological option for dyspnea in cancer patients.

Phase II study of perioperative chemotherapy with cisplatin and pemetrexed in non-small-cell lung cancer.

INTRODUCTION: Pathologic complete response (pCR) with neoadjuvant chemotherapy is associated with improved survival in many solid tumors. We evaluated pCR rate of cisplatin with pemetrexed in non-small-cell lung cancer. METHODS: Patients with stages IB to IIIA non-small-cell lung cancer, Eastern Cooperative Oncology Group performance status 0 to 1 were enrolled in this single-arm phase II trial using two-stage design with 90% power to detect pCR rate of more than or equal to 10%. Pretreatment mediastinal lymph node biopsy was required. Patients received three cycles of cisplatin 75 mg/m with pemetrexed 500 mg/m (day 1 every 21 days) preoperatively and additional two cycles within 60 to 80 days after surgery. The primary end point was pCR. Polymorphisms in FPGS, GGH, SLC19A1, and TYMS genes were correlated with treatment outcomes. RESULTS: Thirty-eight patients were enrolled, with median age of 62.5 years. Preoperatively, 26% had squamous histology, and 34% had biopsy-proven N2 involvement. R0 resection was achieved in 94% of the 34 patients who underwent surgery, and 54% had documented N2 clearance. There was no pCR seen. Median disease-free survival (DFS) and overall survival of these patients have not yet been reached in contrast to median of 13.8 and 24.2 months, respectively, in patients with persistent N2 disease (p = 0.3241 and p = 0.1022, respectively). There was a statistically significant association between DFS and postoperative tumor, node, metastasis stage (p = 0.0429), SLC19A1 rs3788189 TT genotype (p = 0.0821), and viable tumor defined as less than or equal to 10% of resected specimen (p = 0.026). CONCLUSION: The primary end point was not met. Patients with N2 clearance, less than or equal to 10% viable tumor in the resected specimen, and SLC19A1 rs3788189 TT genotype have favorable DFS outcomes.
