RESUMO

OBJECTIVES: To examine relationships in mindfulness and illness acceptance and psychosocial functioning in patients with metastatic breast cancer and their family caregivers. SAMPLE & SETTING: 33 dyads from an academic cancer center in the United States. METHODS & VARIABLES: Participants completed questionnaires on mindfulness, illness acceptance, relationship quality, anxiety, and depressive symptoms. Dyadic, cross-sectional data were analyzed using actor-partner interdependence models. RESULTS: Greater nonjudging, acting with awareness, and illness acceptance among caregivers were associated with patients' and caregivers' perceptions of better relationship quality. Higher levels of these processes were associated with reduced anxiety and depressive symptoms in patients and caregivers. IMPLICATIONS FOR NURSING: Aspects of mindfulness and illness acceptance in dyads confer benefits that are primarily intrapersonal in nature. Nurses may consider introducing mindfulness and acceptance-based interventions to patients and caregivers with adjustment difficulties.

RESUMO

VEGF blockade does not uniformly result in clinical benefit. We evaluated safety, dose-limiting toxicities (DLT), recommended phase II dose (RP2D), antitumor efficacy, and exploratory biomarkers including pharmacogenomics and pharmacokinetics with sorafenib, bevacizumab, and paclitaxel in patients with refractory cancers. The study had a "3 + 3" design, using paclitaxel 80 mg/m2 every week for 3 weeks, in every 4 week cycles, bevacizumab 5 mg/kg every 2 weeks, and sorafenib 200 or 400 mg twice a day, 5 or 7 days/week (5/7, 7/7). The MTD cohort was expanded. Twenty-seven patients enrolled in 3 cohorts: sorafenib 200 mg twice a day 5/7, 200 mg twice a day 7/7, and 400 mg twice a day 5/7. DLTs were grade 3 neutropenia >7 days (cohort 1, 1), grade 3 hypertension (cohort 2, 1), grade 3 hand-foot skin reaction (HFSR; cohort 3, 2). MTD was sorafenib 200 mg twice a day 7/7. Six DLTs occurred in cohort 2 expansion: grade 3 HFSR (2), grade 2 HFSR with sorafenib delay >7 days (2), grade 4 cerebrovascular accident (1), grade 3 neutropenia >7 days (1). RP2D was sorafenib 200 mg twice a day 5/7. Most patients (62%) dose reduced sorafenib to 200 mg daily 5/7 after a median 3 (range, 2-17) cycles. Response rates were 48% overall (27) and 64% for ovarian cancers (14). VEGF-A-1154AA and -7TT recessive homozygous genotypes conferred worse overall survival versus alternative genotypes (7 vs. 22 months). Intermittent, low-dose sorafenib (200 mg twice a day 5/7) combined with bevacizumab and paclitaxel was tolerable and had high antitumor efficacy in patients with refractory cancer (NCT00572078).

RESUMO

Recent clinical trials have demonstrated that aromatase inhibitors (AIs) are slightly more effective than tamoxifen at reducing breast cancer recurrences. However, breast cancer patients receiving AIs have a higher incidence of musculoskeletal symptoms, particularly joint pain and stiffness. Musculoskeletal pain and stiffness can lead to noncompliance and increased utilization of health care resources. There is a suggestion that the syndrome is the result of estrogen deprivation and may share components with autoimmune diseases such as Sjögren's syndrome. Several factors may increase the likelihood of developing AI arthralgia, such as prior chemotherapy, prior hormone replacement therapy, and increased weight; there are inconsistencies with regard to the data on genetic predispositions to this syndrome. While several studies have been done to evaluate interventions to treat or prevent AI arthralgia, no clear treatment has emerged as being particularly beneficial. Much of the research has been limited by small sample size, difficulty blinding patients to placebo, inconsistent definitions of the syndrome, multiple patient reported outcomes, lack of objective outcome measures and heterogeneous patient populations. We are at the early stages of research in characterizing, understanding etiology, preventing and treating AI arthralgias; however much work is being done in this area which, hopefully, will ultimately improve the lives of women with breast cancer.

RESUMO

PURPOSE: To define the safety, efficacy, and pharmacogenetic and pharmacodynamic effects of sorafenib with gemcitabine-based chemoradiotherapy (CRT) in locally advanced pancreatic cancer. METHODS AND MATERIALS: Patients received gemcitabine 1000 mg/m(2) intravenously weekly × 3 every 4 weeks per cycle for 1 cycle before CRT and continued for up to 4 cycles after CRT. Weekly gemcitabine 600 mg/m(2) intravenously was given during concurrent intensity modulated radiation therapy of 50 Gy to gross tumor volume in 25 fractions. Sorafenib was dosed orally 400 mg twice daily until progression, except during CRT when it was escalated from 200 mg to 400 mg daily, and 400 mg twice daily. The maximum tolerated dose cohort was expanded to 15 patients. Correlative studies included dynamic contrast-enhanced MRI and angiogenesis genes polymorphisms (VEGF-A and VEGF-R2 single nucleotide polymorphisms). RESULTS: Twenty-seven patients were enrolled. No dose-limiting toxicity occurred during induction gemcitabine/sorafenib followed by concurrent CRT. The most common grade 3/4 toxicities were fatigue, hematologic, and gastrointestinal. The maximum tolerated dose was sorafenib 400 mg twice daily. The median progression-free survival and overall survival for 25 evaluable patients were 10.6 and 12.6 months, respectively. The median overall survival for patients with VEGF-A -2578 AA, -1498 CC, and -1154 AA versus alternate genotypes was 21.6 versus 14.7 months. Dynamic contrast-enhanced MRI demonstrated higher baseline K(trans) in responding patients. CONCLUSIONS: Concurrent sorafenib with CRT had modest clinical activity with increased gastrointestinal toxicity in localized unresectable pancreatic cancer. Select VEGF-A/VEGF-R2 genotypes were associated with favorable survival.

RESUMO

BACKGROUND: Paced respiration has been internationally recommended for vasomotor symptom management, despite limited empirical evidence. OBJECTIVE: To evaluate efficacy of a paced respiration intervention against breathing control and usual care control for vasomotor and other menopausal symptoms. DESIGN: A 16-week, 3-group, partially blinded, controlled trial with 2:2:1 randomization and stratification by group (breast cancer, no cancer), in a Midwestern city and surrounding area. PARTICIPANTS: Two hundred and eighteen randomized women (96 breast cancer survivors, 122 menopausal women without cancer), recruited through community mailings and registries (29 % minority). INTERVENTIONS: Training, home practice support, and instructions to use the breathing at the time of each hot flash were delivered via compact disc with printed booklet (paced respiration intervention) or digital videodisc with printed booklet (fast shallow breathing control). Usual care control received a letter regarding group assignment. MAIN MEASURES: Hot flash frequency, severity, and bother (primary); hot flash interference in daily life, perceived control over hot flashes, and mood and sleep disturbances (secondary). Intervention performance, adherence, and adverse events were assessed. KEY RESULTS: There were no significant group differences for primary outcomes at 8-weeks or 16-weeks post-randomization. Most intervention participants did not achieve 50 % reduction in vasomotor symptoms, despite demonstrated ability to correctly do paced respiration and daily practice. Statistically significant differences in secondary outcomes at 8 and 16 weeks were small, not likely to be clinically relevant, and as likely to favor intervention as breathing control. CONCLUSIONS: Paced respiration is unlikely to provide clinical benefit for vasomotor or other menopausal symptoms in breast cancer survivors or menopausal women without cancer.

RESUMO

Introduction This phase II trial investigated chemoradiation followed by surgery and 2 years of adjuvant tetrathiomolybdate (TM) for resectable esophageal cancer. Methods Patients with resectable, locally advanced esophageal cancer received neoadjuvant cisplatin 60 mg/m(2) (days 1 and 22), paclitaxel 60 mg/m(2) (days 1, 8, 15, and 22), and 45 Gy hyperfractionated radiotherapy for 3 weeks followed by transhiatal esophagectomy. TM 20 mg PO QD was started 4 weeks post-op, and continued for 2 years to maintain the ceruloplasmin level between 5 and 15 mg/dl. Results Sixty-nine patients were enrolled (median age, 60 years). Sixty-six patients underwent surgery and 61 patients had a complete resection. Histologic complete response rate was 10 %. Twenty-one patients did not receive TM (metastases noted in the peri-operative period, prolonged post-operative recovery time, or patient refusal). Forty-eight patients started TM; 14 completed 24 months of treatment, 11 completed 10-18 months, 15 completed 2-8 months, and 8 completed ≤1 month. Twenty-seven patients had disease recurrence. With a median follow-up of 55 months, 25 patients were alive without disease, 1 was alive with disease, and 43 have died. Three-year recurrence-free survival was 44 % (95 % CI, 32-55 %) and the three-year overall survival was 45 % (95 % CI 33-56 %). Conclusions TM is an antiangiogenic agent that is well tolerated in the adjuvant setting. Disease-free survival and overall survival are promising when compared to historical controls treated at our institution with a similar regimen that did not include TM. However, the challenges associated with prolonged administration limit further investigation.

RESUMO

Angiogenesis is implicated in the pathogenesis of malignancy and metastasis. Inhibition of angiogenesis has demonstrated clinically significant improvements in outcomes in a variety of malignancies, including breast cancer. The humanized monoclonal antibody against VEGF, bevacizumab, is the clinically most mature of the antiangiogenic agents and has recently been shown to improve outcome when combined with chemotherapy in the first-line metastatic setting of breast cancer. A variety of other antiangiogenic agents are currently under investigation, including drugs that inhibit the VEGF receptor 2, the cognate receptor for VEGF found on endothelial cells. The combination of antiangiogenic drugs with one another and with other biologic agents is also being explored in an attempt to improve efficacy and to overcome the drug resistance seen with the initial studies of antiangiogenic agents. This Review will focus on the current state of therapeutics designed to inhibit this angiogenic process in breast cancer.
