Breast Cancer Research and Treatment | Year: 2017

Purpose: Tools to estimate survival, such as ePrognosis (http://eprognosis.ucsf.edu/carey2.php), were developed for general, not cancer, populations. In older patients with breast cancer, accurate overall survival estimates would facilitate discussions about adjuvant therapies. Methods: Secondary analyses were performed of data from two parallel breast cancer studies (CALGB/Alliance 49907/NCT000224102 and CALGB/Alliance 369901/NCT00068328). We included patients (n = 971) who were age 70 years and older with complete baseline quality of life data (194 from 49907; 777 from 369901). Estimated versus observed all-cause two-year mortality rates were compared. ePrognosis score was calculated based on age, sex, and daily function (derived from EORTC QLQ-C30). ePrognosis scores range from 0 to 10, with higher scores indicating worse prognosis based on mortality of community-dwelling elders and were categorized into three groups (0–2, 3–6, 7–10). Observed mortality rates were estimated using Kaplan–Meier methods. Results: Patient mean age was 75.8 years (range 70–91) and 73% had stage I–IIA disease. Most patients were classified by ePrognosis as good prognosis (n = 562, 58% 0–2) and few (n = 18, 2% 7–10) poor prognosis. Two-year observed mortality rates were significantly lower than ePrognosis estimates for patients scoring 0–2 (2% vs 5%, p = 0.001) and 3–6 (8% vs 12%, p = 0.01). The same trend was seen with scores of 7–10 (23% vs 36%, p = 0.25). Conclusions: ePrognosis tool only modestly overestimates mortality rate in older breast cancer patients enrolled in two cooperative group studies. This tool, which estimates non-cancer mortality risk based on readily available clinical information may inform adjuvant therapy decisions but should be validated in non-clinical trial populations. © 2017 Springer Science+Business Media New York

Purpose: This randomized, multicenter, blinded, placebo-controlled phase III trial tested the efficacy and safety of bevacizumab (BV) with gemcitabine and carboplatin (GC) compared with GC in platinum-sensitive recurrent ovarian, primary peritoneal, or fallopian tube cancer (ROC). Patients and Methods: Patients with platinum-sensitive ROC (recurrence ≥ 6 months after front-line platinum-based therapy) and measurable disease were randomly assigned to GC plus either BV or placebo (PL) for six to 10 cycles. BV or PL, respectively, was then continued until disease progression. The primary end point was progression-free survival (PFS) by RECIST; secondary end points were objective response rate, duration of response (DOR), overall survival, and safety. Results: Overall, 484 patients were randomly assigned. PFS for the BV arm was superior to that for the PL arm (hazard ratio [HR], 0.484; 95% CI, 0.388 to 0.605; log-rank P < .0001); median PFS was 12.4 v 8.4 months, respectively. The objective response rate (78.5% v 57.4%; P < .0001) and DOR (10.4 v 7.4 months; HR, 0.534; 95% CI, 0.408 to 0.698) were significantly improved with the addition of BV. No new safety concerns were noted. Grade 3 or higher hypertension (17.4% v <1%) and proteinuria (8.5% v < 1%) occurred more frequently in the BV arm. The rates of neutropenia and febrile neutropenia were similar in both arms. Two patients in the BV arm experienced GI perforation after study treatment discontinuation. Conclusion: GC plus BV followed by BV until progression resulted in a statistically significant improvement in PFS compared with GC plus PL in platinum-sensitive ROC. © 2012 by American Society of Clinical Oncology.

Background The NSABP B-35 trial compared 5 years of treatment with anastrozole versus tamoxifen for reducing subsequent occurrence of breast cancer in postmenopausal patients with ductal carcinoma in situ. This report assesses the effect of these drugs on quality of life and symptoms. Methods The study was done at 333 hospitals in North America. Postmenopausal women with hormone-positive ductal carcinoma in situ treated by lumpectomy with clear resection margins and whole breast irradiation were randomly assigned to receive either tamoxifen (20 mg/day) or anastrazole (1 mg/day) for 5 years, stratified by age (<60 years vs ≥60 years). Patients and investigators were masked to treatment allocation. Patients completed questionnaires at baseline and every 6 months thereafter for 6 years. The primary outcomes were SF-12 physical and mental health component scale scores, and vasomotor symptoms (as per the BCPT symptom scale). Secondary outcomes were vaginal symptoms and sexual functioning. Exploratory outcomes were musculoskeletal pain, bladder symptoms, gynaecological symptoms, cognitive symptoms, weight problems, vitality, and depression. We did the analyses by intention to treat, including patients who completed questionnaires at baseline and at least once during follow-up. This study is registered with ClinicalTrials.gov, NCT00053898. Findings Between Jan 6, 2003, and June 15, 2006, 3104 patients were enrolled in the study, of whom 1193 were included in the quality-of-life substudy: 601 assigned to tamoxifen and 592 assigned to anastrozole. We detected no significant difference between treatment groups for: physical health scores (mean severity score 46·72 for tamoxifen vs 45·85 for anastrozole; p=0·20), mental health scores (52·38 vs 51·48; p=0·38), energy and fatigue (58·34 vs 57·54; p=0·86), or symptoms of depression (6·19 vs 6·39; p=0·46) over 5 years. Vasomotor symptoms (1·33 vs 1·17; p=0·011), difficulty with bladder control (0·96 vs 0·80; p=0·0002), and gynaecological symptoms (0·29 vs 0·18; p<0·0001) were significantly more severe in the tamoxifen group than in the anastrozole group. Musculoskeletal pain (1·50 vs 1·72; p=0·0006) and vaginal symptoms (0·76 vs 0·86; p=0·035) were significantly worse in the anastrozole group than in the tamoxifen group. Sexual functioning did not differ significantly between the two treatments (43·65 vs 45·29; p=0·56). Younger age was significantly associated with more severe vasomotor symptoms (mean severity score 1·45 for age <60 years vs 0·65 for age ≥60 years; p=0·0006), vaginal symptoms (0·98 vs 0·65; p<0·0001), weight problems (1·32 vs 1·02; p<0·0001), and gynaecological symptoms (0·26 vs 0·22; p=0·014). Interpretation Given the similar efficacy of tamoxifen and anastrozole for women older than age 60 years, decisions about treatment should be informed by the risk for serious adverse health effects and the symptoms associated with each drug. For women younger than 60 years old, treatment decisions might be driven by efficacy (favouring anastrozole); however, if the side-effects of anastrozole are intolerable, then switching to tamoxifen is a good alternative.

Purpose: A phase II study of dasatinib, an inhibitor of multiple oncogenic tyrosine kinases including Src, was conducted to evaluate 16-week progression-free rate and tolerability in patients with previously treated metastatic breast cancer (MBC). Real-time assessment of potential tissue biomarkers of Src inhibition was used to optimize dosing. Experimental Design: Eligibility criteria required that patients have measurable MBC, biopsiable tumor, and unlimited prior therapies. For the analysis of change in protein biomarkers of Src inhibition, focal adhesion kinase, paxillin, and p-Src, patients underwent metastatic biopsies at baseline and 4 weeks. Patients who tolerated the starting dose of dasatinib (50 or 70 mg orally twice daily) for the first 28-day cycle, and displayed suboptimal Src inhibition, were escalated to a higher dose (70 or 100 mg). Results: The trial was closed early with 31 patients because of a statistical boundary that required at least 4 (13%) patients without disease progression to continue accrual. These 31 patients had a median of 2 prior lines of chemotherapy for MBC. The most notable toxicity was pleural effusions in 16 patients (52%). Twenty patients had evaluable metastatic biopsies. None of the tumors showed the predefined optimal level of Src inhibition at week 4. Conclusions: Single-agent dasatinib did not exhibit significant antitumor activity in patients with heavily pretreated MBC. There were no clinically meaningful decreases before and after dasatinib exposure between exploratory tissue biomarkers of Src inhibition which may be attributable to challenges in defining biomarker endpoints for multitargeted tyrosine kinase inhibitors. ©2011 AACR.

Objectives: A phase II clinical trial compared docetaxel in combination with carboplatin to sequential single agent docetaxel followed by carboplatin for treatment of recurrent platinum-sensitive ovarian, peritoneal, or tubal cancer. This manuscript reports prospectively collected health-related quality of life (HRQL). Methods: Participants were randomized to either weekly docetaxel 30 mg/m 2/days 1 and 8 and carboplatin AUC 6/day 1 every 3 weeks (cDC) or docetaxel 30 mg/m 2/days 1 and 8, repeated every 3 weeks for 6 cycles followed by carboplatin AUC 6/day 1 every 3 weeks for 6 cycles or until disease progression (sDC). The primary HRQL endpoint was the trial outcome index (TOI) score of the Functional Assessment of Cancer Therapy-Ovarian (FACT-O) instrument, and was assessed as an intent-to-treat analysis. The secondary HRQL endpoints included the FACT-O total score, the FACT-General, and several domain scores of the FACT-O instrument (physical well-being (PWB), social/family well-being (SWB), emotional well-being (EWB), functional well-being (FWB), and the ovarian cancer specific (OCS) module). The FACT-O was administered at randomization, prior to each of 6 cycles of treatment, and at study endpoint. Results: One hundred forty-eight participants were randomized to each group. Sequential docetaxel followed by carboplatin (sDC) was associated with significant improvements in the FACT-O TOI (p = 0.013), FACT-O total score (p = 0.033), and OCS (p = 0.029) compared to the combination docetaxel and carboplatin group (cDC). Conclusions: Sequential single agent docetaxel followed by carboplatin is associated with improved HRQL when compared to cDC. The improved progression-free survival observed with cDC should be weighed against lower quality of life during treatment. © 2011 Elsevier Inc. All rights reserved.

BACKGROUND: The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum-sensitive epithelial ovarian cancer (EOC). METHODS: Participants were randomized to either weekly docetaxel 30 mg/m 2 on days 1 and 8 and carboplatin area under the curve (AUC) = 6 on day 1, every 3 weeks or docetaxel 30 mg/m 2 on days 1 and 8, every 3 weeks for 6 cycles followed by carboplatin AUC = 6 on day 1, every 3 weeks for 6 cycles or until disease progression. The primary endpoint was measurable progression-free survival (PFS). RESULTS: Between January 2004 and March 2007, 150 participants were enrolled. The response rate was 55.4% and 43.2% for those treated with cDC and sDC, respectively. The median PFS was 13.7 months (95% confidence interval [CI], 9.9-16.8) for cDC and 8.4 months (95% CI, 7.1-11.0) for sDC. On the basis of an exploratory analysis, patients treated with sDC were at a 62% increased risk of disease progression compared to those treated with cDC (hazard ratio = 1.62; 95% CI, 1.08-2.45; P =.02). The median overall survival time was similar in both groups (33.2 and 30.1 months, P =.2). The incidence of grade 2 or 3 neurotoxicity and grade 3 or 4 neutropenia was higher with cDC than with sDC (11.7% vs 8.5%; 36.8% vs 11.3%). The sDC group demonstrated significant improvements in the Functional Assessment for Cancer Therapy-Ovarian, Quality of Life Trial Outcome Index scores compared with the combination cohort (P =.013). CONCLUSIONS: Both cDC and sDC regimens have activity in recurrent platinum-sensitive EOC with acceptable toxicity profiles. The cDC regimen may provide a PFS advantage over sDC. © 2011 American Cancer Society.

Objectives: This study aimed to determine the effect of a moderate, tailored exercise program on health-related quality of life, physical function, and arm volume in women receiving treatment for nonmetastatic breast cancer. Methods: Women who were within 4-12 weeks of surgery for stage I-III breast cancer were randomized to center-based exercise and lymphedema education intervention or patient education. Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B), 6-min walk, and arm volume were performed at 3-month intervals through 18 months. Repeated measures analysis of covariance was used to model the total meters walked over time, FACT-B scores, and arm volume. Models were adjusted for baseline measurement, baseline affected arm volume, number of nodes removed, age, self-reported symptoms, baseline SF-12 mental and physical component scores, visit, and treatment group. Results: Of the recruited 104 women, 82 completed all 18 months. Mean age (range) was 53.6 (32-82) years; 88% were Caucasian; 45% were employed full time; 44% were overweight; and 28% obese. Approximately, 46% had breast-conserving surgery; 79% had axillary node dissection; 59% received chemotherapy; and 64% received radiation. The intervention resulted in an average increase of 34.3 ml (SD = 12.8) versus patient education (p = 0.01). Changes in FACT-B scores and arm volumes were not significantly different. Conclusions: With this early exercise intervention after breast cancer diagnosis, a significant improvement was achieved in physical function, with no decline in health-related quality of life or detrimental effect on arm volume. Implications for cancer survivors: Starting a supervised exercise regimen that is tailored to an individual's strength and stamina within 3 months following breast cancer surgery appears safe and may hasten improvements in physical functioning. © 2011 Springer Science+Business Media, LLC.

BACKGROUND: In a randomized controlled trial (RCT) of patients with recurrent, platinum-sensitive ovarian cancer, the combination weekly docetaxel and carboplatin was associated a with progression-free survival (PFS) of 13.7 months compared with 8.4 months for sequential, single-agent docetaxel followed by carboplatin. The objective of the current study was to construct a cost-utility model to compare these 2 regimens with the incorporation of prospectively collected quality-of-life (QoL) data. METHODS: An RCT of concurrent docetaxel and carboplatin (cDC) versus docetaxel followed by carboplatin (sequential docetaxel and carboplatin [sDC]) was the basis for a Markov decision model, and the primary effectiveness outcome was PFS. Costs were estimated using US dollars based on Medicare reimbursements for chemotherapy regimens, bone marrow support, and management of adverse events. QoL data obtained using the Functional Assessment of Cancer Therapy-General questionnaire were converted to utilities. Costs and incremental cost-effectiveness ratios (ICERs) were reported in US dollars per quality-adjusted life year (QALY). Extensive 1-way sensitivity analyses and a Monte Carlo probabilistic sensitivity analysis were performed. RESULTS: The least expensive strategy was sDC, which cost an average of $20,381, compared with cDC, which cost an average of $25,122. cDC had an ICER of $25,239 per QALY compared with sDC. cDC remained cost-effective, with an ICER <$50,000 per QALY, over a range of costs and estimates. In Monte Carlo sensitivity analysis using a $50,000 per QALY willingness-to-pay threshold, cDC was either dominant or cost-effective with an ICER <$50,000 per QALY in 83% of simulations. CONCLUSIONS: Combined weekly cDC appeared to be cost-effective compared with sDC as treatment strategy for patients with platinum-sensitive ovarian cancer, even when accounting for slightly lower QoL during treatment. © 2011 American Cancer Society.

Background Triple negative metastatic breast cancer can be difficult to treat with primarily cytotoxic options. Nab-paclitaxel has demonstrated improved PFS and tolerability compared with standard cremophor-solubilized paclitaxel; based on this, we examined the efficacy and safety of combining weekly nab-paclitaxel with carboplatin and bevacizumab in TNMBC. Patients and Methods In this phase II, multicenter trial, patients with first-line TNMBC received nab-paclitaxel (100 mg/m2) and carboplatin (area under the curve = 2) on days 1, 8, 15, and bevacizumab (10 mg/kg) on days 1 and 15 of a 28-day cycle. The primary end point was safety and tolerability and secondary end points included PFS, ORR, and CBR. PFS was calculated using the Kaplan-Meier method. Results Between July 16, 2007, and October 3, 2011, 34 patients were enrolled at 4 centers. Median age was 50.0 (range, 30-76) years and 77% (n = 26) of patients received previous adjuvant therapy. Median PFS was 9.2 months (95% confidence interval [CI], 7.8-25.1 months). The CBR was 94% (95% CI, 80%-99%), and ORR was 85% (95% CI, 69%-95%) for the combination. The regimen was well tolerated with the most common grade 3/4 adverse events being neutropenia (n = 18; 53%) and thrombocytopenia (n = 6; 18%), with other serous events including 1 grade 3 and 1 grade 4 thrombotic event and 1 febrile neutropenia. Conclusion The combination of nab-paclitaxel, bevacizumab, and carboplatin as first-line treatment for TNMBC was efficacious and well tolerated. The PFS, CBR, and ORR, and tolerability of the regimen, compares favorably with other standard first-line therapies. © 2013 Elsevier Inc. All rights reserved.
