Purpose:Surgery often represents the best chance for disease control in locoregionally recurrent squamous cell carcinoma of the head and neck (SCCHN). We investigated dual immune-checkpoint inhibition [anti–PD-1, nivolumab (N), and anti-KIR, lirilumab (L)] before and after salvage surgery to improve disease-free survival (DFS).Patients and Methods:In this phase II study, patients received N (240 mg) + L (240 mg) 7 to 21 days before surgery, followed by six cycles of adjuvant N + L. Primary endpoint was 1-year DFS; secondary endpoints were safety, pre-op radiologic response, and overall survival (OS). Correlatives included tumor sequencing, PD-L1 scoring, and immunoprofiling.Results:Among 28 patients, the median age was 66, 86% were smokers; primary site: 9 oral cavity, 9 oropharynx, and 10 larynx/hypopharynx; 96% had prior radiation. There were no delays to surgery. Grade 3+ adverse events: 11%. At the time of surgery, 96% had stable disease radiologically, one had progression. Pathologic response to N + L was observed in 43% (12/28): 4/28 (14%) major (tumor viability, TV ≤ 10%) and 8/28 (29%) partial (TV ≤ 50%). PD-L1 combined positive score (CPS) at surgery was similar regardless of pathologic response (P = 0.71). Thirteen (46%) recurred (loco-regional = 10, distant = 3). Five of 28 (18%) had positive margins, 4 later recurred. At median follow-up of 22.8 months, 1-year DFS was 55.2% (95% CI, 34.8–71.7) and 1-year OS was 85.7% (95% CI, 66.3–94.4). Two-year DFS and OS were 64% and 80% among pathologic responders.Conclusions:(Neo)adjuvant N + L was well tolerated, with a 43% pathologic response rate. We observed favorable DFS and excellent 2-year OS among high-risk, previously treated patients exhibiting a pathologic response. Further evaluation of this strategy is warranted.

Purpose: Taxane-induced peripheral neuropathy (TIPN) is an important survivorship issue for many cancer patients. Currently, there are no clinically implemented biomarkers to predict which patients might be at increased risk for TIPN. We present a comprehensive approach to identification of genetic variants to predict TIPN.Experimental Design: We performed a genome-wide association study (GWAS) in 3,431 patients from the phase III adjuvant breast cancer trial, ECOG-5103 to compare genotypes with TIPN. We performed candidate validation of top SNPs for TIPN in another phase III adjuvant breast cancer trial, ECOG-1199.Results: When evaluating for grade 3–4 TIPN, 120 SNPs had a P value of −4 from patients of European descent (EA) in ECOG-5103. Thirty candidate SNPs were subsequently tested in ECOG-1199 and SNP rs3125923 was found to be significantly associated with grade 3–4 TIPN (P = 1.7 × 10−3; OR, 1.8). Race was also a major predictor of TIPN, with patients of African descent (AA) experiencing increased risk of grade 2–4 TIPN (HR, 2.1; P = 5.6 × 10−16) and grade 3–4 TIPN (HR, 2.6; P = 1.1 × 10−11) compared with others. An SNP in FCAMR, rs1856746, had a trend toward an association with grade 2–4 TIPN in AA patients from the GWAS in ECOG-5103 (OR, 5.5; P = 1.6 × 10−7).Conclusions: rs3125923 represents a validated SNP to predict grade 3-4 TIPN. Genetically determined AA race represents the most significant predictor of TIPN. Clin Cancer Res; 21(22); 5082–91. ©2015 AACR.

Purpose: Targeting mutations leading to PI3K/mTOR/Akt activation are of interest in thyroid cancer. We evaluated the efficacy of everolimus in aggressive, radioactive iodine–refractory (RAIR) thyroid cancer and correlated tumor mutational profiling with response. Exploratory medullary and anaplastic thyroid cancer cohorts were included.Experimental Design: This single-arm, multi-institutional phase II study was conducted from 2009 to 2013 in patients with incurable RAIR thyroid cancer who had radiographic progression six months prior to enrollment. The primary endpoint was progression-free survival (PFS) with a median follow-up of 31.8 months. The study is closed to enrollment but treatment and follow-up are ongoing. A targeted next-generation sequencing platform was used for mutational analysis.Results: Thirty-three patients with differentiated thyroid cancer (DTC), 10 with medullary thyroid cancer (MTC), and 7 with anaplastic thyroid cancer (ATC) enrolled. For the DTC cohort, median PFS was 12.9 months (95% CI, 7.3–18.5) with a 2-year PFS of 23.6% (95% CI, 10.5–39.5). Median OS was not reached; 2-year OS was 73.5% (95% CI, 53.8–85.8). Among ATC patients, 1 had a partial response and was progression-free until 17.9 months after study entry and one had disease stability for 26 months, respectively. The genomically profiled cohort enriched for PI3K/mTOR/Akt alterations. PI3K/mTOR/Akt–mutated ATC subgroups appeared to benefit from everolimus. Treatment-related adverse events were as anticipated.Conclusions: Everolimus has significant antitumor activity in thyroid cancer. While genomic profiling does not currently guide therapeutic selection in thyroid cancer patients, these data have important implications when considering the use of an mTOR inhibitor in an era of precision medicine.

Purpose: Anthracycline-induced congestive heart failure (CHF) is a rare but serious toxicity associated with this commonly employed anticancer therapy. The ability to predict which patients might be at increased risk prior to exposure would be valuable to optimally counsel risk-to-benefit ratio for each patient. Herein, we present a genome-wide approach for biomarker discovery with two validation cohorts to predict CHF from adult patients planning to receive anthracycline.Experimental Design: We performed a genome-wide association study in 3,431 patients from the randomized phase III adjuvant breast cancer trial E5103 to identify single nucleotide polymorphism (SNP) genotypes associated with an increased risk of anthracycline-induced CHF. We further attempted candidate validation in two independent phase III adjuvant trials, E1199 and BEATRICE.Results: When evaluating for cardiologist-adjudicated CHF, 11 SNPs had a P value −5, of which nine independent chromosomal regions were associated with increased risk. Validation of the top two SNPs in E1199 revealed one SNP rs28714259 that demonstrated a borderline increased CHF risk (P = 0.04, OR = 1.9). rs28714259 was subsequently tested in BEATRICE and was significantly associated with a decreased left ventricular ejection fraction (P = 0.018, OR = 4.2).Conclusions: rs28714259 represents a validated SNP that is associated with anthracycline-induced CHF in three independent, phase III adjuvant breast cancer clinical trials.

Myeloid suppressor cells with high arginase activity are found in tumors and spleen of mice with colon and lung cancer. These cells, described as macrophages or immature dendritic cells, deplete arginine and impair T cell proliferation and cytokine production. Although arginase activity has been described in cancer patients, it is thought to originate from tumor cells metabolizing arginine to ornithine needed to sustain rapid cell proliferation. The goal of this study was to determine whether myeloid suppressor cells producing high arginase existed in renal cell carcinoma patients. Peripheral blood mononuclear cells from 123 patients with metastatic renal cell carcinoma, prior to treatment, were found to have a significantly increased arginase activity. These patients had a markedly decreased cytokine production and expressed low levels of T cell receptor CD3ζ chain. Cell separation studies showed that the increased arginase activity was limited to a specific subset of CD11b+, CD14−, CD15+ cells with a polymorphonuclear granulocyte morphology and markers, instead of macrophages or dendritic cells described in mouse models. Furthermore, these patients had low levels of arginine and high levels of ornithine in plasma. Depletion of the CD11b+, CD14− myeloid suppressor cells reestablished T cell proliferation and CD3ζ chain expression. These results showed, for the first time, the existence of suppressor myeloid cells producing arginase in human cancer patients. In addition, it supports the concept that blocking arginase may be an important step in the success of immunotherapy.

Aim A case report on the diagnosis and treatment of this rare low grade triple negative breast cancer. Case Report A 41 year old female presented with a palpable left breast lump. Family history includes a sister with a rare myeloproliferative disorder. On examination, a left breast lower outer quadrant 2–3 cm hard irregular lump was palpable. Mammography and ultrasound revealed a 25 mm suspicious lesion (which was biopsied), with normal appearing lymph nodes. Results Biopsy revealed a grade 2 invasive apocrine carcinoma. Oestrogen and Herceptin receptors negative. Breast conserving surgery with sentinel lymph node biopsy was performed. Histology revealed a 22 mm well circumscribed tumour with nests of epithelial cells in micropapillary pattern with apocrine like appearance. The most striking feature was that the nuclei were at the apical rather than the basal poles of the epithelial cells (reverse polarity). No lymphovascular invasion present. Lymph nodes were negative (0/3). Diagnosis was then confirmed by molecular testing. Conclusion Tall cell carcinoma with reverse polarity (TCCRP)1, a rare cancer resembling tall cell variant of papillary thyroid carcinoma, was first reported by Eusebi et al in 20032. Although morphologically similar to metastatic papillary thyroid cancer, neither the immunohistochemical markers nor genetic profiles have established any connection3. Accurate diagnosis of TCCRP is important as it carries an excellent prognosis. Treatment is local regional radiotherapy. There is no indication for systemic therapy in this case, due to its indolent low metastatic potential.

The objective of this study was to evaluate the impact of insurance and neighborhood SES (nSES) on chemotherapy completion and overall mortality among participants in breast cancer clinical trials. The data sources for this study were two adjuvant breast cancer trials (ECOG E1199 and E5103) collectively including 9790 women. Insurance status at trial registration was categorized into private, government (Medicaid, Medicare, and other government type insurance), and self‐pay. An Agency for Healthcare Research Quality (AHRQ) nSES index was calculated using residential zip codes linked to county level data on occupation, income, poverty, wealth, education, and crowding. Logistic regression and Cox Proportional Hazard models estimated odds ratios (OR) for chemotherapy treatment completion and hazard ratios (HR) for mortality, respectively, for insurance status and nSES. The models adjusted for: race, age, tumor size, nodal status, hormone receptor status, and primary surgery. The majority of patients had private insurance at trial registration: E1199: 85.6% (4154/4854) and E5103: 82.4% (3987/4836); median SES index was 53.8 (range: 41.8‐66.8) and 54.1 (range: 44.5‐66.1), respectively. Patients with government insurance were less likely to complete chemotherapy treatment (E1199 OR (95%CI): 0.73 (0.57‐0.94); E5103 0.76 (0.64‐0.91)) and had an increased risk of death (E1199 HR (95%CI): 1.44 (1.22‐1.70); E5103 1.29 (1.06‐1.58)) compared to the privately insured patients. There was no association between nSES and chemotherapy completion or overall mortality. Patients with government insurance at trial registration appeared to face barriers in chemotherapy completion and had a higher overall mortality compared to their privately insured counterparts.

Breast cancer treatment can impact not only short-term health but may also affect longer-term quality of life (QOL).To describe and evaluate factors associated with diminished QOL following completion of active treatment.This was a secondary analysis of a randomized clinical trial included patients with lymph node-positive or high-risk lymph node-negative breast cancer who had undergone definitive surgery and were enrolled in ECOG-ACRIN E5103, a multisite phase 3 trial. A survey was administered 18 months after enrollment to patients enrolled between January and June 2010. Final analysis of the data took place from March to December 2021.Patients received adjuvant doxorubicin, cyclophosphamide, and paclitaxel with either bevacizumab or placebo.QOL and health status assessed with the EuroQol 5-Dimension 3-Levels (EQ-5D-3L), EQ-visual analog scale (EQ-VAS), and the Functional Assessment of Cancer Therapy-Breast Cancer, with arm subscale (FACT-B+4). Groups were compared by Fisher exact test, Wilcoxon rank sum, or Kruskal-Wallis test. Multivariable linear regression was used to assess factors independently associated with FACT-B scores.Data at 18 months were available from 455 of 519 patients (87.7%) enrolled in the trial. Median (range) age at enrollment was 52 (25-76) years. No differences in QOL (median [range] FACT-B scores: group A, 123 [67-146]; group B, 114 [54-148]; group C, 117 [42-148]; P = .23) or health status (median [range] EQ-5D-3L index scores: group A, 0.83 [0.28-1.00]; group B, 0.83 [0.20-1.00]; group C, 0.83 [0.17-1.00], P = .80; median EQ-VAS: group A, 85 [20-100]; group B, 85 [0-100]; group C, 85 [0-100]; P = .79) were observed across treatment groups; results for subsequent analyses were therefore reported irrespective of primary treatment. Overall, half of patients (258 of 444 [58%]) reported at least some pain or discomfort; 170 (38%) reported symptoms of anxiety or depression. In multivariable analyses, mastectomy with radiation (vs breast conserving surgery) and Asian, Black, or American Indian or Alaska Native race (vs White race) were associated with lower QOL (mastectomy with radiation: coefficient: -5.5; 95% CI, -10.1 to -0.9; Asian, Black, or American Indian or Alaska Native race: coefficient: -7.3; 95% CI, -13.2, -1.4).In this study, the addition of bevacizumab to chemotherapy was not negatively associated with QOL at 18 months. A substantial proportion of participants reported problems related to pain or discomfort and anxiety or depression, demonstrating persistent consequences for physical and psychosocial well-being in this heavily treated population. Many problems reported are amenable to intervention, underscoring the need for timely referral to supportive resources, especially for women of color and those who have more extensive local therapy.ClinicalTrials.gov Identifier: NCT00433511.

To systematically search the literature to identify studies related to clinical supervision in child and family health nurse contexts, and to determine the role it has in professional practice and the characteristics required for effective supervision.A mixed-method systematic review using a convergent integrative approach to data synthesis.Studies only in English language were identified from searches of CINAHL, MEDLINE and EMBASE databases covering the years of publication from January 1990 to December 2020.Primary research studies of clinical supervision with child and family health nurses in community settings were included. Studies were critically appraised for methodological quality and data extracted, coded and analysed for themes in keeping with the review aims and key findings of each study.Of 2185 records screened, 63 full-text papers were assessed for eligibility, which yielded 12 publications for inclusion-11 from the United Kingdom and one from Sweden. The majority (75%) of included studies were qualitative or mixed method. Four main themes with sub-themes were identified: structural features, supportive experience, ensuring safety and strengthening practice.Clinical supervision across child and family health nurse contexts is limited. This study highlighted organizational commitment to clinical supervision as an important component of safe and quality practice. Supervisor training and supervisee orientation to supervision is required to optimize effective participation, together with shared agreement of the goals and purpose of supervision.The findings from this review confirm the potential for clinical supervision to support improved outcomes for children and families. Understanding what models work best and in what contexts will inform workplace policy and educational programs for child and family nurses across diverse settings.

Purpose: Surgery often represents the best chance for disease control in locoregionally recurrent squamous cell carcinoma of the head and neck (SCCHN). We investigated dual immune-checkpoint inhibition [anti–PD-1, nivolumab (N), and anti-KIR, lirilumab (L)] before and after salvage surgery to improve disease-free survival (DFS). Patients and Methods: In this phase II study, patients received N (240 mg) + L (240 mg) 7 to 21 days before surgery, followed by six cycles of adjuvant N + L. Primary endpoint was 1-year DFS; secondary endpoints were safety, pre-op radiologic response, and overall survival (OS). Correlatives included tumor sequencing, PD-L1 scoring, and immunoprofiling. Results: Among 28 patients, the median age was 66, 86% were smokers; primary site: 9 oral cavity, 9 oropharynx, and 10 larynx/hypopharynx; 96% had prior radiation. There were no delays to surgery. Grade 3+ adverse events: 11%. At the time of surgery, 96% had stable disease radiologically, one had progression. Pathologic response to N + L was observed in 43% (12/28): 4/28 (14%) major (tumor viability, TV ≤ 10%) and 8/28 (29%) partial (TV ≤ 50%). PD-L1 combined positive score (CPS) at surgery was similar regardless of pathologic response (P = 0.71). Thirteen (46%) recurred (loco-regional = 10, distant = 3). Five of 28 (18%) had positive margins, 4 later recurred. At median follow-up of 22.8 months, 1-year DFS was 55.2% (95% CI, 34.8–71.7) and 1-year OS was 85.7% (95% CI, 66.3–94.4). Two-year DFS and OS were 64% and 80% among pathologic responders. Conclusions: (Neo)adjuvant N + L was well tolerated, with a 43% pathologic response rate. We observed favorable DFS and excellent 2-year OS among high-risk, previously treated patients exhibiting a pathologic response. Further evaluation of this strategy is warranted.

Systemic inflammation is believed to contribute to the distant recurrence of breast cancer. We evaluated serum samples obtained at diagnosis from 249 case:control pairs with stage II-III Her2-negative breast cancer with or without subsequent distant recurrence. Conditional logistic regression analysis, with models fit via maximum likelihood, were used to estimate hazard ratios (HRs) and test for associations of cytokines with distant recurrence risk. The only biomarker associated with a significantly increased distant recurrence risk when adjusted for multiple testing was the proinflammatory cytokine IL-6 (HR 1.37, 95% confidence intervals [CI] 1.15, 1.65, p = 0.0006). This prospective-retrospective study provides evidence indicating that higher levels of the cytokine IL-6 at diagnosis are associated with a significantly higher distant recurrence risk.

Purpose Bevacizumab improves progression-free survival but not overall survival in patients with metastatic breast cancer. E5103 tested the effect of bevacizumab in the adjuvant setting in patients with human epidermal growth factor receptor 2–negative disease. Patients and Methods Patients were assigned 1:2:2 to receive placebo with doxorubicin and cyclophosphamide (AC) followed by weekly paclitaxel (arm A), bevacizumab only during AC and paclitaxel (arm B), or bevacizumab during AC and paclitaxel followed by bevacizumab monotherapy for 10 cycles (arm C). Random assignment was stratified and bevacizumab dose adjusted for choice of AC schedule. Radiation and hormonal therapy were administered concurrently with bevacizumab in arm C. The primary end point was invasive disease–free survival (IDFS). Results Four thousand nine hundred ninety-four patients were enrolled. Median age was 52 years; 64% of patients were estrogen receptor positive, 27% were lymph node negative, and 78% received dose-dense AC. Chemotherapy-associated adverse events including myelosuppression and neuropathy were similar across all arms. Grade ≥ 3 hypertension was more common in bevacizumab-treated patients, but thrombosis, proteinuria, and hemorrhage were not. The cumulative incidence of clinical congestive heart failure at 15 months was 1.0%, 1.9%, and 3.0% in arms A, B, and C, respectively. Bevacizumab exposure was less than anticipated, with approximately 24% of patients in arm B and approximately 55% of patients in arm C discontinuing bevacizumab before completing planned therapy. Five-year IDFS was 77% (95% CI, 71% to 81%) in arm A, 76% (95% CI, 72% to 80%) in arm B, and 80% (95% CI, 77% to 83%) in arm C. Conclusion Incorporation of bevacizumab into sequential anthracycline- and taxane-containing adjuvant therapy does not improve IDFS or overall survival in patients with high-risk human epidermal growth factor receptor 2–negative breast cancer. Longer duration bevacizumab therapy is unlikely to be feasible given the high rate of early discontinuation.

OBJECTIVES: To assess the long-term outcomes and objective response to pre-radiation chemotherapy and radiation in adult high-risk medulloblastoma. METHODS: In this prospective phase II trial, adults with high-risk medulloblastoma were treated with three cycles of pre-radiation cisplatin, etoposide, cyclophosphamide, and vincristine followed by craniospinal radiation (CSI). Objective response (OR), progression free survival (PFS), overall survival (OS), and toxicities were assessed. RESULTS: Eleven patients were enrolled over a 6 year period. Six (55%) had subarachnoid metastases. Two (18%) had an OR to pre-radiation chemotherapy. Two (18%) progressed while on chemotherapy. Completion of CSI was not compromised. The OR rate after chemotherapy and radiation was 45 % (5/11). Non-evaluable patients at both time points weakened the response data conclusions. Median PFS was 43.8 months. Five year PFS was 27%. Five year OS was 55%. Non-metastatic (M0) and metastatic (M+) patients had similar outcomes. CONCLUSIONS: The OR to this pre-radiation chemotherapy regimen is lower than anticipated from the adult and pediatric literature raising a question about comparative efficacy of chemotherapy in different age groups. The OS achieved is similar to retrospective adult series, but worse than pediatric outcomes. Although this regimen can be administered without compromising delivery of CSI, our results do not provide support for the use of this neoadjuvant chemotherapy for adult medulloblastoma.

Purpose: Targeting mutations leading to PI3K/mTOR/Akt activation are of interest in thyroid cancer. We evaluated the efficacy of everolimus in aggressive, radioactive iodine–refractory (RAIR) thyroid cancer and correlated tumor mutational profiling with response. Exploratory medullary and anaplastic thyroid cancer cohorts were included. Experimental Design: This single-arm, multi-institutional phase II study was conducted from 2009 to 2013 in patients with incurable RAIR thyroid cancer who had radiographic progression six months prior to enrollment. The primary endpoint was progression-free survival (PFS) with a median follow-up of 31.8 months. The study is closed to enrollment but treatment and follow-up are ongoing. A targeted next-generation sequencing platform was used for mutational analysis. Results: Thirty-three patients with differentiated thyroid cancer (DTC), 10 with medullary thyroid cancer (MTC), and 7 with anaplastic thyroid cancer (ATC) enrolled. For the DTC cohort, median PFS was 12.9 months (95% CI, 7.3–18.5) with a 2-year PFS of 23.6% (95% CI, 10.5–39.5). Median OS was not reached; 2-year OS was 73.5% (95% CI, 53.8–85.8). Among ATC patients, 1 had a partial response and was progression-free until 17.9 months after study entry and one had disease stability for 26 months, respectively. The genomically profiled cohort enriched for PI3K/mTOR/Akt alterations. PI3K/mTOR/Akt–mutated ATC subgroups appeared to benefit from everolimus. Treatment-related adverse events were as anticipated. Conclusions: Everolimus has significant antitumor activity in thyroid cancer. While genomic profiling does not currently guide therapeutic selection in thyroid cancer patients, these data have important implications when considering the use of an mTOR inhibitor in an era of precision medicine.

Purpose: Recurrent or metastatic adenoid cystic carcinoma (R/M ACC) is a rare cancer often arising from the salivary glands of the head and neck. While effective therapies are lacking, preclinical models have suggested that retinoic acid agonists may inhibit ACC growth by blocking MYB binding at translocated gene enhancers. We conducted a phase II trial evaluating retinoic acid as a potential novel therapy for R/M ACC. Patients and methods: Patients with histologically confirmed R/M ACC of any primary site with measurable disease (RECIST v1.1), clinical or radiographic progression within 12 months prior to enrollment, and any number of prior lines of therapy were eligible. Cohort 1 (CH1) received ATRA 45 mg/m2 split oral daily dosing on days 1-14 of a 28-day cycle; cohort 2 (CH2) received the same dosing continuously; treatment continued until disease progression. The primary endpoint was best overall response: ≥5 patients in CH1 with disease in response (CR+PR) among N=25 (assuming ≥2 of N=14 accrued in first stage of a two-stage design had disease in response) provided 85% power to target a >10% response rate (one-sided 9% binomial test). Secondary endpoints: safety, progression-free survival (PFS), overall survival. Exploratory analyses: ATRA impact on MYB expression, define resistance mechanisms, and monitor circulating tumor DNA. All had targeted tumor sequencing prior to enrollment. Results: Between 8/2019 and 2/2020, N=14 enrolled in stage 1 CH1. Primary endpoint of response to continue accrual into stage 2 in CH1 was not met; by 5/2020, N=4 enrolled in CH2 when the trial closed to accrual (budget constraints). Among 18 patients, median age: 58, 61% (11/18) women; each patient had a median of 3 organs (range, 1-4) with metastatic disease. 39% had 2+ prior lines of therapy. Best overall response: CR+PR 0%; SD 61% (11/18); PD 28% (5/18); unevaluable 11% (2/18). Median duration of stability 3.5 months (range, 1-12.3+). One patient (CH1) remains on drug with SD >1 year. Half of those who received prior VEGFR therapy achieved SD (4/8). At a median follow-up of 7.9 months, median PFS was 3.2 months (95% CI, 1.8-3.9). N=1 required dose adjustment; N=1 came off drug for toxicity. There were no grade 3-4 adverse events (headache, dry skin were common); no deaths due to treatment. Median tumor mutational burden was 0 (range, 0-5). NOTCH1 was the most frequent alteration (4, 22%) with 2 evaluable NOTCH1-mutant patients exhibiting SD. Mutations in the PI3K pathway, TP53, and TERT promoter were common. Low MYB protein expression was associated with longer duration of stability (p Citation Format: Glenn J.

Rituximab has demonstrated activity in PCNSL. E1F05 is an ECOG-ACRIN multicenter phase 2 prospective trial of rituximab with high-dose methotrexate (HD-MTX)-based chemotherapy similar to the RTOG 93-10 regimen, omitting radiotherapy. Methods: Immunocompetent patients with newly diagnosed PCNSL received HD-MTX 3.5g/m2 with vincristine every two weeks for 5 doses; procarbazine for 7 days in weeks 1, 5, and 9; cytarabine 3g/m2/day IV for 2 days in weeks 11 and 14; a dexamethasone taper over 6 weeks; and rituximab 375mg/m2 IV infusion 3 times per week for weeks 1-4. Subjects with CSF involvement received intrathecal methotrexate 12mg every two weeks. Results: Twenty-six patients were enrolled; median age was 57. Sixteen subjects (65%) completed treatment per protocol; the most common reason for discontinuation was adverse events, and 2 subjects discontinued due to progressive disease (PD). Complete response (CR) + unconfirmed CR (CRu) was 16/25 (64%), overall response rate was 20/25 (80%), and 4/25(16%) had PD as best response. Median progression free survival (PFS) was 34 months, and median overall survival has not been reached at 40 months’ median follow up. Two year PFS was 63%. The most common grade 3-4 toxicities were hematologic. Conclusion: The addition of rituximab to multi-agent chemotherapy is well tolerated. Outcomes are comparable to or better than those seen in RTOG 93-10, which included RT. These and other results suggest rituximab has activity in the CNS.

This study aimed to examine how biomarker information would impact patients’ preferences and physicians’ recommendations for adjuvant breast cancer therapy. At the 18-month follow-up, participants in a large, double-blind randomized controlled trial of adjuvant chemotherapy with bevacizumab or placebo (E5103) were surveyed about their preferred treatment (either chemotherapy A alone or chemotherapy A+B) in two hypothetical scenarios: (1) without biomarker information; and (2) after learning that they tested positive for a “B-receptor” which modestly increased both the benefit and toxicity expected with chemotherapy A+B. We performed a cross-sectional analysis of the prospectively collected survey data and used the McNemar’s test to examine changes in treatment preferences. A one-time survey of clinical investigators who enrolled patients on the trial evaluated physician recommendations in response to the same biomarker information. 439 patients completed both scenarios on 18-month survey. Most participants preferred A+B in both scenario 1 and 2 (77 and 76% respectively). The increase in benefit and toxicity associated with the positive biomarker information in scenario 2 led 60/439 (14%) of patients to switch their treatment preference. The corresponding physician survey revealed that most physicians chose regimen A+B in scenario 1 (77%), and moreso after the biomarker information was available in scenario 2 (84%). Information about a positive biomarker indicating increased benefit and toxicity from additional chemotherapy did not change many participants’ preferred treatment. The majority preferred the most effective course in both scenarios. Similarly, most investigators discounted increased toxicity and valued increased benefit. Parent Trial Registration: NCT00433511

BACKGROUND Published studies have suggested that most patients with early stage breast cancer are willing, for modest survival benefits, to receive 6 months of adjuvant cyclophosphamide, methotrexate, and 5-fluorouracil, an older regimen that is used infrequently today. We examined preferences regarding the survival benefit needed to justify 6 months of a contemporary chemotherapy regimen. METHODS The Eastern Cooperative Oncology Group Protocol 5103 was a phase 3 trial that randomized breast cancer patients to receive standard adjuvant doxorubicin, cyclophosphamide, and paclitaxel with either bevacizumab or placebo. Serial surveys to assess quality of life were administered to patients enrolled between January 1, 2010, and June 8, 2010. Survival benefit needed to justify 6 months of chemotherapy by patients was collected at the 18-month assessment. A parallel survey was sent to physicians who had enrolled patients in the study. RESULTS Of 519 patients who had not withdrawn at a time point earlier than 18 months, 87.8% responded to this survey. A total of 175 physicians participated. We found considerable variation in patient preferences, particularly for modest survival benefits: for 2 months of benefit, 57% would consider 6 months of chemotherapy, whereas 96% of patients would consider 6 months of chemotherapy for 24 months. Race and education were associated with the choices. Physicians who responded were less likely to accept chemotherapy for modest benefit. CONCLUSIONS Among patients who received contemporary adjuvant chemotherapy in a randomized controlled trial, we found substantial variation in preferences regarding benefits that justified undergoing chemotherapy. Differences between patients' and physicians' choices were also apparent. Eliciting preferences regarding risks and benefits of adjuvant chemotherapy is critical.

6527 Background: Social determinants of health (SDH) and genetic ancestry have been independently implicated in breast cancer presentation, treatment and mortality. However, little is known about the relationship between SDH and genetic ancestry on clinical trial outcomes. The objective of this study is to assess the association between SDH, genetic ancestry and clinical outcomes in patients enrolled in an adjuvant breast cancer clinical trial. Methods: ECOG-ACRIN (EA) 5103 randomized patients to receive AC + taxane + bevacizumab or placebo. SDH were operationalized as insurance status at trial registration (individual SES) and neighborhood socioeconomic status (nSES). Insurance categories included: (1) Private, 2) Medicare including private/Medicare, military, 3) Medicaid including Medicaid/Medicare, uninsured, 4) self-pay). The nSES index was calculated using zip codes linked to county level data on occupation, income, poverty, wealth, education and crowding. Genome-wide single-nucleotide polymorphism arrays were used to define African ancestry (AA), European ancestry (EA) and other (OA). Multivariable regression and Cox-Proportional Hazard models (odds ratios (OR) and hazard ratios (HR) with corresponding 95% confidence intervals (CI)) were used to assess associations with chemotherapy completion and overall mortality. Estimates were adjusted for the following clinical covariates: age, tumor size, nodal status, hormone receptor status, and primary surgery at randomization. Results: The study cohort included 2453 EA (79.2%), 381 AA (12.2%) and 265 OA (8.6%). Medicaid patients (OR 0.76(0.59-0.99); ref private) and those with AA (OR 0.62(0.49-0.78); ref EA) were less likely to complete chemotherapy. Regarding overall mortality, Medicaid insurance (HR 1.42(1.05-1.92) was associated with a higher mortality than private insurance. Conversely, there was no significant difference in mortality by ancestry (AA HR 1.27 (0.97-1.66); OA HR 0.90 (0.63-1.29): ref EA). Neighborhood socioeconomic status did not appear to be associated with chemotherapy completion or mortality. Conclusions: SDH reflective of individual SES, such as insurance, appear to be stronger drivers of trial completion and mortality compared to nSES among patients enrolled in E5103. Moreover, study results suggest an interplay between ancestry and individual proxies for SDH in trial completion. Nevertheless, the relationship between ancestry and lower rates of chemotherapy completion do not appear to translate into higher mortality rates among patients of AA.

6080 Background: Recurrent respiratory papillomatosis (RRP) is caused by human papillomavirus (HPV) types 6 & 11. RRP proliferates in the respiratory tract impacting breathing, swallowing, and voice and carries a 1-4% risk of malignant transformation.There is no curative therapy for RRP. Given the tolerized host immune response against HPV, the safety and efficacy of pembrolizumab (pembro) as an alternative treatment for this patient population was evaluated in a phase II clinical trial. Patient reported outcomes (PROs) were assessed during the trial to capture the patient perspective of pembro as an alternative to surgery or in office procedures, both standard of care (SOC). Methods: RRP patients who had previously undergone >3 procedures in any year, or with known tracheal or pulmonary involvement prior to study entry were treated with pembro 200mg every 3 weeks. The primary endpoint of the trial was best ‘overall response rate’ (ORR) measured by an endoscopic-based disease burden score (lower score reflects better ‘response’) and/or RECIST 1.1, secondary endpoint included PROs. Twenty-one patients were required to assess the primary endpoint. Most of the QoL surveys used Likert scale to assess PROs (‘never, sometimes, often, most of the time, always’). The percentage reporting ’never’ having an issue with symptom or activity at baseline, 6 months, and at time of ORR (nadir disease burden score) is reported here. Results: Twenty-one patients were accrued. Median age (range) was 45 (19-68), 57% (12/21) were male and 67% (14/21) were white. Questionnaire completion rates were 100% at baseline, 90% at 6 months, and 85% at ORR. Improvement in: social interactions (less difficulty with: physical intimacy [38%,56%,65% reporting ‘never’ at baseline, 6 months, and at ORR respectively]), discussing disease diagnosis [19%,21%,39%]); personal feelings (less depression [14%,32%,33%], less anxiety [5%,16%,22%], less embarrassment [19%,37%,50%]), and work-related absences (less frequently fabricating reasons for work absence due to disease-related treatment [57%,78%,56%] and less utilization of family vacation or FMLA for disease treatment [29%,53%,56%]) were reported. At ORR, 72% (13/18) patients reported that IV infusion was not emotionally burdensome and 78% (14/18) reported it as the preferred treatment relative to their perceived experience with SOC surgery or in office procedures. Conclusions: PRO results show consistent benefit in key aspects of the patient experience with pembro over procedure based SOC further supporting its overall clinical benefit in patients with HPV-associated RRP.

520 Background: Systemic inflammation may contribute to cancer progression (PMC2803035), including recurrence of early breast cancer (PMC4828958). We hypothesized that inflammatory cytokines and/or chemokines may be associated with distant recurrence (DR). Methods: We performed a case:control study in women with stage II-III Her2-negative breast cancer, all of whom had surgery and adjuvant chemotherapy (doxorubicin/cyclophosphamide, then weekly paclitaxel) with/without bevacizumab, plus endocrine therapy if ER-positive (PMC6118403). Propensity score matching was used to identify approximately 250 case:control pairs (with/without DR). Serum samples obtained before adjuvant chemotherapy were analyzed using the MSD V-Plex Human Cytokine 36-Plex Kit for detection of human cytokines and chemokines involved in the Th1/Th2 pathway, chemotaxis, the Th17 pathway, angiogenesis, and immune system regulation. Conditional logistic regression analysis, with models fit via maximum likelihood, were used to estimate hazard ratios (HRs) and test for associations. Due to skewed nature of cytokines, HRs are reported on log base 2 scale. If adjusted for multiple testing including 36 markers, a p value of < 0.0014 would be required for statistical significance. Results: A total 249 matched pairs (498 patients) were identified. Covariates used for propensity score matching included age, menopausal status (post 54% vs. pre/peri 46%), ER/PR status (one/both pos 64% vs. both neg 36%) tumor size ( < = 2cm 17%, > 2-5cm 67%, > 5cm 16%) nodal status (neg 15%,1-3+ 32%, 4+ 53%), and grade (low 3%, int. 31%, high 66%). The only biomarker associated with a significantly increased DR risk when adjusted for multiple testing was the proinflammatory cytokine IL-6 (HR 1.37, 95% confidence intervals [CI] 1.15, 1.65, p = 0.0006). Others associated with a 2-sided p value < 0.05 included the chemokine MDC(macrophage-derived chemokine/CCL22) (1.90, 95% CI 1.17, 3.1, p = 0.0098), the T helper cell inflammatory cytokine IL-17A (HR 1.36, 95% CI 1.10, 1.67, p = 0.0052), and the cytokine VEGF-A (HR 1.13 for, 95% CI 1.01, 1.27, p = 0.037). There was no statistical interaction between VEGF-A and bevacizumab benefit. The median and mean value for IL-6 was 0.95 and 7.5 pg/ml (range 0.04-2761.24 pg/ml). Conclusions: This analysis provides level 1B evidence indicating that higher levels of the cytokine IL-6 at diagnosis are associated with a significantly higher DR risk in high-risk stage II-III breast cancer despite optimal adjuvant systemic therapy. This provides a foundation for confirmatory validation of IL-6 as a prognostic biomarker, and potentially as a predictive biomarker for testing therapeutic interventions targeting the IL-6/JAK/STAT3 pathway.

6053 Background: Locoregional recurrence (LRR) is a major cause of death for patients (pts) with squamous cell carcinoma of the head and neck (SCCHN). With therapy options limited by prior treatment, surgery often represents the best chance for disease control. Emerging data suggests a role for neoadjuvant immunotherapy in upfront resectable SCCHN and the importance of NK cells in the tumor microenvironment. We hypothesized that dual immune checkpoint inhibition (anti-PD-1, nivolumab [N] and anti-KIR, lirilumab [L]) before and after salvage surgery would improve 1-year disease-free survival (DFS). Methods: Pts with operable LRR of SCCHN (any HPV or smoking status) with a disease-free interval of > 8 weeks after curative intent therapy were eligible for this phase II trial. Pts received a single dose of pre-op N (240 mg) + L (240 mg) 7-21 days before surgery, followed by 6-cycles of adjuvant N+L on days 1, 15 (N alone) of a 28-day cycle (C) for C1-3; and on day 1 for C4-6. Primary endpoint was 1-year DFS; 37 DFS events among N = 54 pts provided 81% power to detect improvement in 1-year DFS from 57% to 67.5% (one-sided 10% Wald’s test). Secondary endpoints: safety, radiologic response (RECIST v1.1) to pre-op N+L, and overall survival (OS). Correlatives included tumor sequencing, PD-L1 status, and immunoprofiling. Results: Between 3/15/18 and 5/29/20, N = 29 enrolled (stopped due to expiration of drug supply). Among 28 treated pts, median age: 66, 18% (5/28) women, 83% smokers; primary site: 10 oral cavity, 8 oropharynx (5/8 HPV+), and 10 larynx/hypopharynx. 96% (27/28) had prior HN radiation; 71% (20/28) prior chemotherapy. There were no delays to surgery. Grade 3+ adverse events: 11% (3/28); no deaths from treatment. At time of surgery, 96% (27/28) had stable disease radiologically with 3 showing regression, 4% (1/28) had disease progression. Pathologic response to N+L was observed in 43% (12/28): 4/28 (14%) major (tumor viability, TV ≤10%); 8/28 (29%) partial (TV ≤50%). PD-L1 CPS at surgery was similar regardless of pathologic response (p = 0.63). 68% (19/28) completed all 6-cycles of adjuvant N+L; N = 1 came off for toxicity. Ten pts (36%) recurred (local = 8, distant = 2). 5/28 (18%) had positive margins, of which 4 (80%) recurred; 4/28 (14%) declined to start adjuvant N+L, of which 3 (75%) later recurred. At median follow-up of 20.2 months, 1-year DFS70% (95%CI, 48-84%) and 1-year OS: 85% (95%CI, 65-94%). Median tumor mutational burden was 4 (range, 1-11). TP53 was the most frequent alteration (78%, 21/27). CD39 expression by TILs and CD38 expression by circulating CD4/8+ T cells increased after N+L exposure (p < 0.05). Conclusions: Neoadjuvant and adjuvant N+L was safe and well tolerated. We observed a 43% pathologic response rate prior to salvage surgery, with a favorable 1-year DFS of 70% and 1-year OS > 80% among previously irradiated pts. Further evaluation of this strategy is warranted (NCT03341936).

Schneider, email: // Keywords : whole exome sequencing, African American, paclitaxel, peripheral neuropathy, SBF2 Received : August 29, 2016 Accepted : September 18, 2016 Published : October 09, 2016 Abstract Purpose: Taxane-induced peripheral neuropathy (TIPN) is one of the most important survivorship issues for cancer patients. African Americans (AA) have previously been shown to have an increased risk for this toxicity. Germline predictive biomarkers were evaluated to help identify a priori which patients might be at extraordinarily high risk for this toxicity. Experimental design: Whole exome sequencing was performed using germline DNA from 213 AA patients who received a standard dose and schedule of paclitaxel in the adjuvant, randomized phase III breast cancer trial, E5103. Cases were defined as those with either grade 3-4 (n=64) or grade 2-4 (n=151) TIPN and were compared to controls (n=62) that were not reported to have experienced TIPN. We retained for analysis rare variants with a minor allele frequency

Background: Blockade of human epidermal growth factor receptor type 2 (HER2) has dramatically improved outcome for patients with HER2-positive breast cancer. Trastuzumab, an anti-HER2 monoclonal antibody, has previously demonstrated improvement in overall survival (OS) in patients with metastatic and early stage HER2-positive breast cancer. However, trastuzumab can cause congestive heart failure (CHF) with an increased frequency for patients who have also received an anthracycline. The current trial was designed to evaluate the impact of the duration of trastuzumab on CHF. Methods: E2198 included 227 eligible women with histologically confirmed stage II or IIIA HER2-positive breast cancer. The patients were randomised to receive 12 weeks of paclitaxel and trastuzumab followed by four cycles of doxorubicin and cyclophosphamide (abbreviated Arm) or the aforementioned treatment with additional 1 year of trastuzumab (conventional Arm). The primary end point was to evaluate the safety of this variable duration of trastuzumab therapy, particularly cardiac toxicity defined as CHF or left ventricular ejection fraction decrease >10%. Secondary end points included disease-free survival (DFS) and OS. Results: Compared with 12-week treatment with trastuzumab, 1 year of trastuzumab-based therapy did not increase the frequency or severity of cardiac toxicity: three patients on the abbreviated Arm and four on the conventional Arm experienced CHF. The 5-year DFS was 76% and 73% for the abbreviated and conventional Arms, respectively, with a hazard ratio (HR) of 1.3 (95% CI: 0.8–2.1; P=0.3). There was also no statistically significance difference in OS (HR, 1.4; P=0.3). Conclusions: Compared with 12 weeks of treatment, 1 year of treatment with trastuzumab did not significantly increase the risk of cardiac toxicity. Although not powered for efficacy comparisons, the longer duration of trastuzumab therapy did not demonstrate a signal for marked superiority.

Anthracycline agents can cause cardiotoxicity. We used multivariable risk prediction models to identify a subset of patients with breast cancer at high risk of cardiotoxicity, for whom the harms of anthracycline chemotherapy may balance or exceed the benefits.A clinical prediction model for anthracycline cardiotoxicity was created in 967 patients with human epidermal growth factor receptor-negative breast cancer treated with doxorubicin in the ECOG-ACRIN study E5103. Cardiotoxicity was defined as left ventricular ejection fraction (LVEF) decline of ≥ 10% to 50% and/or a centrally adjudicated clinical heart failure diagnosis. Patient-specific incremental absolute benefit of anthracyclines (compared with non-anthracycline taxane chemotherapy) was estimated using the PREDICT model to assess breast cancer mortality risk.Of the 967 women who initiated therapy, 51 (5.3%) developed cardiotoxicity (12 with clinical heart failure). In a multivariate model, increasing age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01-1.08), higher body mass index (OR, 1.06; 95% CI, 1.02-1.10), and lower baseline LVEF (OR, 0.93; 95% CI, 0.89-0.98) at baseline were significantly associated with cardiotoxicity. The concordance statistic of the risk model was 0.70 (95% CI, 0.63-0.77). In patients with low anticipated treatment benefit (n = 176) from the addition of anthracycline (2% absolute risk difference of breast cancer mortality at 10 years), 16 (9%) of 176 had a10% risk of cardiotoxicity and 61 (35%) of 176 had a 5% to 10% risk of cardiotoxicity at 1 year.Older age, higher body mass index, and lower baseline LVEF were associated with increased risk of cardiotoxicity. We identified a subgroup with low predicted absolute benefit of anthracyclines but with high predicted risk of cardiotoxicity. Additional studies are needed incorporating long-term cardiac outcomes and cardiotoxicity model external validation prior to implementation in routine clinical practice.

Introduction Fluoropyrimidines (FPDs) are a fundamental component of many chemotherapy regimens. Cardiotoxic adverse events (AEs) such as angina, ischemia, arrhythmias, and cardiomyopathy associated with 5-fluorouracil (5-FU) and capecitabine (CAPE) have been sparingly described in studies, primarily through case reports. Data from the 1990s revealed an estimated incidence of 0.5% to 19%, with cardiovascular fatalities occurring in ≤28%. The current use of FPDs includes multiple dosing regimens, oral or intravenous delivery, and administration with additional cardiotoxic therapies. As such, it is imperative to better define the cardiotoxicity risk in the modern treatment era. We comprehensively evaluated the incidence, prevalence, and ascertainment of cardiovascular risk factors and disease within ECOG-ACRIN (Eastern Cooperative Group Cancer Research Group – American College of Radiology Imaging Network) Cancer Research Group clinical trials incorporating 5-FU and CAPE. Materials and Methods Case report forms and clinical study reports from the ECOG-ACRIN Cancer Research Group database of phase II and III clinical trials incorporating 5-FU and CAPE were evaluated. A total of 16 trials from 2002 to 2017 were identified that had used bolus 5-FU (n = 1), continuous infusion 5-FU (n = 10) or CAPE (n = 5). Results A history of cardiovascular disease was variably defined and was an exclusion criterion in 13 of the 16 studies (81%). The baseline risk factors and history of cardiac disease were specifically collected in only 3 studies (19%). All studies collected cardiovascular AEs using the Common Terminology Criteria for Adverse Events version available at the time of the study. Fewer than half (7 of 16; 44%) of the study case report forms had also specifically requested information on cardiac ischemia/infarction. In the 12 completed studies with clinical study reports, the following AEs were reported: dyspnea, ≤16%; arrhythmias, ≤6%; and angina, ischemia, and elevated troponin, ≤5%. Some trials only recorded cardiac AEs that were possibly associated with the novel drug being studied and not those attributed to the standard of care in the 5-FU/CAPE arm, further decreasing the numerical incidence. Conclusion Inconsistent clinical trial reporting of cardiac AEs precluded accurate and precise delineation of the epidemiology of FPD-related cardiovascular AEs. Prospective knowledge of the definition and natural history will lead to the development of risk factor stratification and prechemotherapy interventions to reduce or prevent cardiotoxicity. We propose that the prospective collection of baseline cardiac data and prespecified cardiac endpoints are necessary to fully understand the incidence and cardiac risk of FDPs.

Purpose Racial disparity in breast cancer outcomes exists between African American and white women in the United States. We have evaluated the impact of genetically determined ancestry on disparity in efficacy and therapy-induced toxicity for patients with breast cancer in the context of a randomized, phase III adjuvant trial. Methods This study compared outcomes between 386 patients of African ancestry (AA) and 2,473 patients of European ancestry (EA) in a randomized, phase III breast cancer trial, ECOG-ACRIN-5103. The primary efficacy end point, invasive disease–free survival (DFS), and clinically significant toxicities were compared, including anthracycline-induced congestive heart failure, taxane-induced peripheral neuropathy (TIPN), and bevacizumab-induced hypertension. Results Overall, AAs had significantly inferior DFS ( P = .002; hazard ratio, 1.5) compared with EAs. This was significant in the estrogen receptor–positive subgroup ( P = .03), with a similar, nonsignificant trend for those who had triple-negative breast cancer ( P = .12). AAs also had significantly more grades 3 to 4 TIPN (odds ratio [OR], 2.9; P = 2.4 × 10−11) and grades 3 to 4 bevacizumab-induced hypertension (OR, 1.6; P = .02), with a trend for more congestive heart failure (OR, 1.8; P = .08). AAs had significantly more dose reductions in paclitaxel ( P = 6.6 × 10−6). In AAs, dose reductions in paclitaxel had a significant negative impact on DFS ( P = .03), whereas in EAs, dose reductions did not have an impact on outcome ( P = .35). Conclusion AAs had inferior DFS, with more clinically important toxicities, in ECOG-ACRIN-5103. The altered risk-to-benefit ratio for adjuvant breast cancer chemotherapy should lead to additional research with the focus on the impact of genetic ancestry on both efficacy and toxicity. Strategies to minimize dose reductions in paclitaxel, especially as the result of TIPN, are warranted for this population.

Background Human papillomavirus (HPV) infection indicates favorable prognosis in oropharyngeal squamous cell carcinoma (SCC). The purpose of this study was for us to assess the impact of HPV in patients treated with sequential therapy versus concomitant chemoradiotherapy (CRT). Methods Patients with stage III and IVA and B oropharyngeal SCC were reviewed spanning 10 years. Results Among 500 cases, 291 (58%) received CRT versus 209 (42%) sequential therapy. HPV status was known in 279 of patients (56%) and positive in 77% (determined by polymerase chain reaction [PCR; 91%], p16 immunohistochemical [IHC], or both). Median follow-up was 2.8 years. Overall survival (OS) did not differ for sequential therapy versus CRT overall (hazard ratio [HR] = 0.90; p = .66; 3-year OS = 86% and 87%) or within HPV-positive patients (HR = 0.89; p = .81; 3-year OS = 91% and 91%) or within HPV-negative patients (HR = 0.55; p = .32; 3-year OS = 85% and 75%). Conclusion Survival for all patients was high and notable for HPV-negative patients treated with sequential therapy. Further studies in this patient population are warranted. © 2015 Wiley Periodicals, Inc. Head Neck, 2015

Purpose: Taxane-induced peripheral neuropathy (TIPN) is an important survivorship issue for many cancer patients. Currently, there are no clinically implemented biomarkers to predict which patients might be at increased risk for TIPN. We present a comprehensive approach to identification of genetic variants to predict TIPN. Experimental Design: We performed a genome-wide association study (GWAS) in 3,431 patients from the phase III adjuvant breast cancer trial, ECOG-5103 to compare genotypes with TIPN. We performed candidate validation of top SNPs for TIPN in another phase III adjuvant breast cancer trial, ECOG-1199. Results: When evaluating for grade 3–4 TIPN, 120 SNPs had a P value of Conclusions: rs3125923 represents a validated SNP to predict grade 3-4 TIPN. Genetically determined AA race represents the most significant predictor of TIPN. Clin Cancer Res; 21(22); 5082–91. ©2015 AACR.

2590 Background: Recurrent respiratory papillomatosis (RRP) is caused by human papillomavirus (HPV) types 6 & 11. RRP proliferates in the squamous epithelium lining the respiratory tract impacting breathing, swallowing, and voice and carries a 3-5% risk of malignant transformation. Given the multi-focality of the disease and tolerized host immune response against HPV, in part through upregulation of the PD1:PDL1 axis, the safety and efficacy of systemic pembrolizumab (pembro) as a novel treatment for this benign tumor patient (pt) population was evaluated in a phase II clinical trial. Methods: RRP pts > 12 years of age were treated with pembro 200mg every 3 weeks. Primary endpoints were best overall response (ORR) (measured by endoscopic lesional burden) and safety. Greater than 5 pts with disease response out of 21 (assuming > 1 of first n = 11 with disease in response) provided 86% power to distinguish between a 15% and a 38% ORR (one-sided 8% binomial test). HPV-specific CD8+ T cell frequency and functional states and biomarkers of response and immune resistance are being evaluated in serial tissue and liquid biopsies (up to 8 biopsies/patient over the 24 months of treatment). Results: The Simon two-stage, stage 1 criteria was met. A total of 21 patients were enrolled and all are now off treatment. Median age (range) was 45 (19-68), 57% (12/21) were male and 67% (14/21) were white. 48% (10/21) had Juvenile-onset (Jo)-RRP, 57% (12/21) had pulmonary RRP involvement, and 19% (4/21) had SCC derived from their RRP. 62% (13/21) completed 24 months of treatment. Reasons for discontinuation included disease progression (14%, 3/21), treatment related adverse event (TRAEs) (14%, 3/21), and study withdrawal (10%, 2/21). A partial response (≥25% reduction in endoscopic tumor burden score) was observed in 57% (12/21) (95% CI: 34%-78.2%) of pts (7 of 10 with Jo-RRP and 5 of 11 with Adult-onset (Ao)-RRP disease responded). Stable disease was observed in 33% (7/21). No complete responses were observed. Fatigue was the most frequent TRAEs; Grade 3 TRAEs included uveitis and hypophysitis, both of which were reversible upon pembro discontinuation and steroid use. At a median follow-up: 25.6 (6.2-38.1 months), the mean number of surgical interventions was reduced by 7 surgeries/year (p = 0.004) in pts treated on the trial for > 12 months, and, upon treatment completion, durable clinical benefit was observed with no additional treatment needed for the duration of the clinical trial follow-up for some pts. Conclusions: Pembro reduces the need for routine surgical interventions based on the durable response rates being achieved. Further study of pembro +/- other agents is warranted to achieve and sustain complete responses in this population. Clinical trial information: NCT02632344.

Importance Late recurrence 5 or more years after diagnosis accounts for at least one-half of all cases of recurrent hormone receptor–positive breast cancer. Objective To determine whether the presence of circulating tumor cells (CTCs) in a peripheral blood sample obtained approximately 5 years after diagnosis was associated with late clinical recurrence of operable human epidermal growth factor receptor 2–negative breast cancer. Design, Setting, and Participants This per-protocol secondary analysis of the Double-Blind Phase III Trial of Doxorubicin and Cyclophosphamide Followed by Paclitaxel With Bevacizumab or Placebo in Patients With Lymph Node Positive and High Risk Lymph Node Negative Breast Cancer enrolled patients from 2007 to 2011 who were without clinical evidence of recurrence between 4.5 and 7.5 years after primary surgical treatment of human epidermal growth factor receptor 2–negative stage II-III breast cancer followed by adjuvant systemic therapy. Patients were enrolled in a subprotocol for secondary analysis from February 25, 2013, to July 29, 2016, after signing consent for the subprotocol. The analysis was performed in April 2018. Interventions A blood sample was obtained for identification and enumeration of CTCs. Main Outcome and Measures The association between a positive CTC assay result (at least 1 CTC per 7.5 mL of blood) and clinical recurrence. Results Among 547 women included in this analysis, the results of the CTC assay were positive for 18 of 353 with hormone receptor–positive disease (5.1% [95% CI, 3.0%-7.9%]); 23 of 353 patients (6.5% [95% CI, 4.2%-9.6%]) had a clinical recurrence. The recurrence rates per person-year of follow-up in the CTC-positive and CTC-negative groups were 21.4% (7 recurrences per 32.7 person-years) and 2.0% (16 recurrences per 796.3 person-years), respectively. In multivariate models including clinical covariates, a positive CTC assay result was associated with a 13.1-fold higher risk of recurrence (hazard ratio point estimate, 13.1; 95% CI, 4.7-36.3). Seven of 23 patients (30.4% [95% CI, 13.2%-52.9%]) with recurrence had a positive CTC assay result at a median of 2.8 years (range, 0.1-2.8 years) before clinical recurrence. The CTC assay result was also positive for 8 of 193 patients (4.1% [95% CI, 1.8%-8.0%]) with hormone receptor–negative disease, although only 1 patient (0.5% [95% CI, 0%-2.9%]) experienced disease recurrence (this patient was CTC negative). Conclusions and Relevance A single positive CTC assay result 5 years after diagnosis of hormone receptor–positive breast cancer provided independent prognostic information for late clinical recurrence, which provides proof of concept that liquid-based biomarkers may be used to risk stratify for late recurrence and guide therapy.

Summary Objectives There are limited chemotherapeutic options for advanced recurrent or metastatic SCCHN. The efficacy and toxicity of docetaxel with or without vandetanib was investigated in these patients. Materials and Methods Patients with pathologically confirmed, recurrent or metastatic SCCHN who had progressed on platinum based therapy given as definitive or palliative treatment, were randomized in this open label, multicenter phase II study of docetaxel (75 mg/m2 IV Q3 weeks) with or without vandetanib (100 mg PO daily). The primary objective was response rate (RR) and secondary objectives were progression free survival (PFS), overall survival (OS), disease control rate (DCR) and duration of response (DOR). Results 29 analyzable patients were enrolled, 14 in docetaxel arm and 15 in combined arm. PR was achieved in 1 patient in the docetaxel arm and 2 patients in the combined arm. The objective RR was 7% (1/14) (95% CI 0.2–33.8%) in the single and 13% (2/15) (95% CI 1.6–40.4%) combined arm. The median PFS was 3.21 (95% CI 3.0–22.0) and 9 (95% CI (5.86–18.1) weeks; median OS was 26.8(95% CI 17.7–100.7+) and 24.1 (95% CI, 16.4–171.1+) weeks. Most common adverse events were fatigue, dysphagia, diarrhea or constipation, cytopenias and alopecia. Conclusions Although an initial benefit in response was noted and statistical criteria met there was only a minor trend towards improved PFS for the combined arm. The study was designed with low threshold for activity in each arm and results were deemed not to be of enough clinical significance in this group of patients to continue accrual.

Our objective was to better understand the values and ethical dilemmas surrounding advance care planning through stories told by registered nurses and licensed social workers, who were employed as care managers within Area Agencies on Aging. We conducted eight focus groups in which care managers were invited to tell their stories and answer open-ended questions focusing on their interactions with consumers receiving home-based long-term care. Using narrative analysis to understand how our participants thought through particular experiences and what they valued, we identified seven themes representative of their work with consumers and families: humility, respect, responsibilities, boundaries, empowerment, courage, and veracity.

Summary Background The relative efficacy of the addition of induction chemotherapy to chemoradiotherapy compared with chemoradiotherapy alone for patients with head and neck cancer is unclear. The PARADIGM study is a multicentre open-label phase 3 study comparing the use of docetaxel, cisplatin, and fluorouracil (TPF) induction chemotherapy followed by concurrent chemoradiotherapy with cisplatin-based concurrent chemoradiotherapy alone in patients with locally advanced head and neck cancer. Methods Adult patients with previously untreated, non-metastatic, newly diagnosed head and neck cancer were eligible. Patients were eligible if their tumour was either unresectable or of low surgical curability on the basis of advanced tumour stage (3 or 4) or regional-node stage (2 or 3, except T1N2), or if they were a candidate for organ preservation. Patients were randomly assigned (in a 1:1 ratio) to receive either induction chemotherapy with three cycles of TPF followed by concurrent chemoradiotherapy with either docetaxel or carboplatin or concurrent chemoradiotherapy alone with two cycles of bolus cisplatin. A computer-generated randomisation schedule using minimisation was prepared and the treatment assignment was done centrally at one of the study sites. Patients, study staff, and investigators were not masked to group assignment. Stratification factors were WHO performance status, primary disease site, and stage. The primary endpoint was overall survival. Analysis was by intention to treat. Patient accrual was terminated in December, 2008, because of slow enrolment. The trial is registered with ClinicalTrials.gov, number NCT00095875. Findings Between Aug 24, 2004, and Dec 29, 2008, we enrolled 145 patients across 16 sites. After a median follow-up of 49 months (IQR 39–63), 41 patients had died—20 in the induction chemotherapy followed by chemoradiotherapy group and 21 in the chemoradiotherapy alone group. 3-year overall survival was 73% (95% CI 60–82) in the induction therapy followed by chemoradiotherapy group and 78% (66–86) in the chemoradiotherapy alone group (hazard ratio 1·09, 95% CI 0·59–2·03; p=0·77). More patients had febrile neutropenia in the induction chemotherapy followed by chemoradiotherapy group (16 patients) than in the chemoradiotherapy alone group (one patient). Interpretation Although survival results were good in both groups there was no difference noted between those patients treated with induction chemotherapy followed by chemoradiotherapy and those who received chemoradiotherapy alone. We cannot rule out the possibility of a difference in survival going undetected due to early termination of the trial. Clinicians should still use their best judgment, based on the available data, in the decision of how to best treat patients. The addition of induction chemotherapy remains an appropriate approach for advanced disease with high risk for local or distant failure. Funding Sanofi-Aventis.
