Abstract Background Although physical activity has been consistently associated with reduced breast cancer mortality, evidence is largely based on data collected at one occasion. We examined how pre- and postdiagnosis physical activity was associated with survival outcomes in high-risk breast cancer patients. Methods Included were 1340 patients enrolled in the Diet, Exercise, Lifestyle and Cancer Prognosis (DELCaP) Study, a prospective study of lifestyle and prognosis ancillary to a SWOG clinical trial (S0221). Activity before diagnosis, during treatment, and at 1- and 2-year intervals after enrollment was collected. Patients were categorized according to the Physical Activity Guidelines for Americans as meeting the minimum guidelines (yes/no) and incrementally as inactive, low active, moderately active (meeting the guidelines), or high active. Results In joint-exposure analyses, patients meeting the guidelines before and 1 year after diagnosis experienced statistically significant reductions in hazards of recurrence (hazard ratio [HR] = 0.59, 95% confidence interval [CI] = 0.42 to 0.82) and mortality (HR = 0.51, 95% CI = 0.34–0.77); associations were stronger at 2-year follow-up for recurrence (HR = 0.45, 95% CI = 0.31 to 0.65) and mortality (HR = 0.32, 95% CI = 0.19 to 0.52). In time-dependent analyses, factoring in activity from all time points, we observed striking associations with mortality for low- (HR = 0.41, 95% CI = 0.24 to 0.68), moderate- (HR = 0.42, 95% CI = 0.23 to 0.76), and high-active patients (HR = 0.31, 95% CI = 0.18 to 0.53). Conclusions Meeting the minimum guidelines for physical activity both before diagnosis and after treatment appears to be associated with statistically significantly reduced hazards of recurrence and mortality among breast cancer patients. When considering activity from all time points, including during treatment, lower volumes of regular activity were associated with similar overall survival advantages as meeting and exceeding the guidelines.

PURPOSE Despite reported widespread use of dietary supplements during cancer treatment, few empirical data with regard to their safety or efficacy exist. Because of concerns that some supplements, particularly antioxidants, could reduce the cytotoxicity of chemotherapy, we conducted a prospective study ancillary to a therapeutic trial to evaluate associations between supplement use and breast cancer outcomes. METHODS Patients with breast cancer randomly assigned to an intergroup metronomic trial of cyclophosphamide, doxorubicin, and paclitaxel were queried on their use of supplements at registration and during treatment (n =1,134). Cox proportional hazards regression adjusting for clinical and lifestyle variables was used. Recurrence and survival were indexed at 6 months after enrollment using a landmark approach. RESULTS There were indications that use of any antioxidant supplement (vitamins A, C, and E; carotenoids; coenzyme Q10) both before and during treatment was associated with an increased hazard of recurrence (adjusted hazard ratio [adjHR], 1.41; 95% CI, 0.98 to 2.04; P = .06) and, to a lesser extent, death (adjHR, 1.40; 95% CI, 0.90 to 2.18; P = .14). Relationships with individual antioxidants were weaker perhaps because of small numbers. For nonantioxidants, vitamin B12 use both before and during chemotherapy was significantly associated with poorer disease-free survival (adjHR, 1.83; 95% CI, 1.15 to 2.92; P < .01) and overall survival (adjHR, 2.04; 95% CI, 1.22 to 3.40; P < .01). Use of iron during chemotherapy was significantly associated with recurrence (adjHR, 1.79; 95% CI, 1.20 to 2.67; P < .01) as was use both before and during treatment (adjHR, 1.91; 95% CI, 0.98 to 3.70; P = .06). Results were similar for overall survival. Multivitamin use was not associated with survival outcomes. CONCLUSION Associations between survival outcomes and use of antioxidant and other dietary supplements both before and during chemotherapy are consistent with recommendations for caution among patients when considering the use of supplements, other than a multivitamin, during chemotherapy.

The NCCN Guidelines for Survivorship provide screening, evaluation, and treatment recommendations for consequences of cancer and cancer treatment to aid healthcare professionals who work with survivors of adult-onset cancer. Guidance is also provided to help promote physical activity, weight management, and proper immunizations in survivors and to facilitate care coordination to ensure that all needs are addressed. These NCCN Insights summarize some of the topics discussed by the NCCN Survivorship Panel during the 2019 update of the guidelines, including the survivorship population addressed, ways to improve care coordination, and pain management.

521 Background: S0221 investigated weekly vs q 2 week dosing of doxorubicin/cyclophosphamide (AC) and paclitaxel (P) in patients (pts) with high risk early breast cancer as previously reported (JCO 33:58-64, 2015). After enrollment of 2716 pts randomization to the two AC arms was stopped for futility and an additional 578 pts received 4 cycles of q 2 week AC and were randomized to P weekly (Pw) or P q 2 weeks (P2). We report updated results of the original trial design and the first report of the 578 pts treated with AC x 4 and Pw x 12 or P2 x 6. Methods: Between December 2003 and November 2010, 2716 pts were randomized in a 2x2 factorial design to 1) 15 weeks of weekly AC (A 24 mg/m2/week and C 60 mg/m2/day po) vs 6 cycles of q 2 week AC (A 60 mg/m2 and C 600 mg/m2) and 2) Pw (paclitaxel 80 mg/m2/week x 12) vs P2 (paclitaxel 175 mg/m2 q 2 weeks x 6), with growth factor support as previously described. After study amendment 578 patients received 4 cycles of q 2 week AC followed by Pw or P2. Updated survival was assessed using log-rank tests and Cox regression models. Results: At a median follow-up of 8.5 years, among the pts treated in the original protocol, there were no significant differences among the four treatments for DFS (p=0.21) or OS (p=0.08). The triple-negative subset had worse DFS (P<0.001) than the HER2-positive or ER/PR+/HER2- subsets, with 5 year DFS of 75% vs 83% and 84%, respectively. While we previously found in the triple negative subset that the arm using q 2 weeks for both AC and paclitaxel was marginally superior, the differences among the arms are no longer significant for DFS (p=0.12) or OS (p=0.11). Among the 578 pts assigned ACx4 and randomized to Pw v P2 there were no overall differences in DFS (p=0.70) or OS (p=0.63) after 4.4 years median follow-up. Conclusions: There were no significant differences in DFS or OS between any of the schedules with extended follow-up in the original cohort and no difference in outcome by paclitaxel schedule for the 578 additional patients in the revised protocol. Either paclitaxel schedule may be recommended, with selection based on toxicity, cost, or patient preference rather than efficacy.

CRA1008 Background: S0221 is a SWOG-coordinated phase III adjuvant chemotherapy intergroup trial in node-positive and high-risk node-negative operable breast cancer which hypothesized that 1) the weekly AC+G regimen is superior to ddAC x 6 and 2) 12 weeks of weekly paclitaxel (wP) is superior to q 2 week paclitaxel x 6 (ddP). Methods: Between December 2003 and November 2010, 2,716 patients were randomized in a 2 x 2 factorial design to 1) AC+G vs ddAC and 2) P 80 mg/m2/week x 12 vs P 175 mg/m2 q 2 weeks x 6. If there was no significant interaction between the factors, the trial was powered to find a disease-free survival hazard ratio (HR) ≤ 0.82 for weekly vs q 2 week for each factor. At the first interim analysis, the AC randomization was halted for futility, and S0221 was closed to accrual 10 November 2010. S0221 reopened 15 December 2010, after which time all patients received 4 cycles of ddAC and randomization to P weekly x 12 and ddP x 6 continued. Accrual halted at a total of 3,294 in January 2012. Results: By September 7, 2012, 487 events and 340 deaths had occurred, prompting the third planned interim analysis. The Data Safety and Monitoring Committee recommended reporting the results since the futility boundary was crossed. A Cox model adjusting for the AC arms had a HR = 1.08 (95% CI 0.90-1.28; p=0.42), with the 99.5% CI excluding the original alternative hypothesis that the HR=0.82. There was no significant interaction of the two factors. Estimated 5-year progression-free survivals were 82% for weekly P and 81% for ddP. Toxicity data were available for 1,385 patients treated with ddP and 1,367 treated with weekly P. Grade 5 toxicity occurred in 4 patients on ddP and 2 on weekly P. Percent grade 3-4 toxicity per arm are shown in the Table. Conclusions: Either ddPx6 or weekly P x 12 are acceptable schedules of P administration. The differences in leukopenia likely reflect ascertainment bias against weekly P. If this is accepted, weekly P x 12 produces less overall toxicity than 6 cycles of ddP.

Abstract Introduction. Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of paclitaxel treatment. There is conflicting data on the benefits and harms of supplement use for the treatment and prevention of CIPN. We examined dietary supplement use before diagnosis and during treatment in relation to CIPN among breast cancer patients registered to a clinical trial (SWOG 0221; ClinicalTrials.gov Identifier: NCT00070564) before diagnosis and during treatment in relation to CIPN. Methods. At trial registration (baseline), breast cancer patients (n = 1,225) completed questionnaires to capture use before and at diagnosis of multivitamins and other dietary supplements. Of these patients, 1,068 completed a 6-month follow-up questionnaire to capture use during treatment. We examined the use of multivitamins, vitamins C, D, E, B6, and B12, folic acid, iron, calcium, glucosamine, and combined fish oil, eicosapentaenoic acid (EPA), omega-3, flaxseed and cod liver oil at these timepoints in relation to CIPN. CIPN was assessed via the National Cancer Institute Common Toxicity Criteria for Adverse Events (CTCAE) and the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group Neurotoxicity (FACT/GOG-Ntx) subscale. Odds ratios and 95% confidence intervals were computed using unconditional logistic regression. Results. Multivitamin use before diagnosis was associated with reduced symptoms of CIPN (CTCAE adjusted OR = 0.60, 95% CI = 0.42-0.87; FACT/GOG-Ntx adjusted OR = 0.78, 95% CI = 0.61-1.00). Although in a similar direction as use prior to diagnosis, multivitamin use during treatment was less strongly associated with CIPN (CTCAE adjusted OR = 0.73, 95% CI = 0.49-1.08; FACT/GOG-Ntx 0.77, 95% CI = 0.60-0.99). Other supplement use, either before diagnosis or during treatment, was not associated with CIPN. Conclusions. Our results indicate that supplement use during treatment may not appreciably affect experience of CIPN symptoms. Future analyses of the relationships between supplement use and survival outcomes will better inform patient decision making.

Supplement use and chemotherapy-induced peripheral neuropathy in breast cancer patients treated on SWOG study S0221. [abstract].

Abstract Introduction: The use of multi-drug regimens, including taxanes (T), has increased survival for breast cancer patients. However, T-induced neuropathy, one of the most common side effects, cannot be predicted, prevented or effectively treated. Using genome wide analyses (GWA), we sought to identify common genetic variants that infer susceptibility to clinical and self-reported neuropathy. Methods: Women with high risk breast cancer were enrolled in SWOG 0221, a trial of dosing schedules for AC and T. Genotyping was performed using the Illumina 1M chip and SNPs examined in relation to CTCAE grade 3 and 4 neurotoxicity and self-reported symptoms (FACT-TAXANE) among women providing blood samples. Significant associations were tested for replication in CALGB40101. Results: Among 1269 European Americans (EA) and 139 African Americans (AA) in S0221, there were 147 and 31 grade 3+ neuropathies, respectively. In CALGB40101, grade 3 toxicity was less frequent (59/855 EA and 15/117 AA). In S0221 EA patients, loci on chromosomes 7, 10, 16 and 17 showed associations with grades 3 and 4 neuropathy at p&lt;5×10e-06, with the most significant genetic association on chromosome 17, rs910920, p = 6.8×10e-08, odds ratio (OR) = 0.44 (95% confidence interval (CI), 0.32-0.61); this SNP is a cis eQTL, thought likely to affect transcription factor binding and linked to expression of VPS53 in lymphoblastoid cell lines. While the rs910920 association was specific to EA, the A allele in rs1858826 on chromosome 7 was associated with reduced odds of neuropathy in both EA (p = 7×10e-07) and AA (p = .02) groups. The S0221 associations at p&lt;5×10e-06 did not replicate in CALGB40101. A subset of patients (n = 677 EA and n = 42 AA) completed the FACT-TAXANE. The most significant associations with this neuropathy phenotype (p&lt;5×10e-07) were on chromosomes 2 (rs4267555 and rs4443044) and 3 (rs2421468). Of the 168 SNPs tested for association with neuropathy in previous studies, rs1695 in GSTP1 (p = 0.0009) and rs228591 in ATM (p = 0.0006), showed some evidence of association with FACT-TAXANE scores; the latter SNP was significant at p = .005 in ordinal regression analysis of neuropathy grades 0-4 in CALGB40101. None of these SNPs were significantly associated with grade 3 CTCAE neuropathy at p&lt;.05, nor were the top CTCAE associations in relation to FACT-TAXANE scores. Replication of the most significant S0221 FACT-TAXANE findings in CALGB40101 is ongoing. Conclusions: Failure to replicate S0221 in CALGB40101, and the lack of coherence between self-report and clinical grade in S0221 could be attributable to differences in trial designs as well as differences in defining a complex phenotype. Larger homogeneous trials with similar dosing and criteria for defining neuropathy are needed to assess the relationship of genetics and the neuropathy symptom spectrum.
