    Abstract: This study was designed to determine the effect of adding docetaxel (T) to preoperative doxorubicin and cyclophosphamide (AC) on breast cancer response rates and disease-free survival (DFS) and overall survival (OS). Patients and Methods Women with operable breast cancer (N = 2,411) were randomly assigned to receive preoperative AC followed by surgery, AC followed by T and surgery, or AC followed by surgery and then T. Tamoxifen was initiated concurrently with chemotherapy. Median time on study for 2,404 patients with follow-up was 77.9 months. Results Addition of T to AC did not significantly impact DFS or OS. There were trends toward improved DFS with addition of T. The addition of T reduced the incidence of local recurrences as first events (P = .0034). Preoperative T, but not postoperative T, significantly improved DFS in patients who had a clinical partial response after AC (hazard ratio [HR] = 0.71; 95% CI, 0.55 to 0.91; P = .007). Pathologic complete response, which was doubled by addition of preoperative T, was a significant predictor of OS regardless of treatment (HR = 0.33; 95% CI, 0.23 to 0.47; P 〈 .0001). Pathologic nodal status after chemotherapy was a significant predictor of OS (P 〈 .0001). Conclusion The addition of preoperative or postoperative T after preoperative AC did not significantly affect OS, slightly improved DFS, and decreased the incidence of local recurrences. The sample size of this study was not sufficient to yield significance for the moderate DFS improvement. Concurrent use of tamoxifen may have limited the impact of adding T.

    Abstract: Patients with early-stage, hormone receptor–positive breast cancer have considerable residual risk for recurrence after completing 5 years of adjuvant tamoxifen. In May 2001, the National Surgical Adjuvant Breast and Bowel Project (NSABP) initiated accrual to a randomized, placebo-controlled, double-blind clinical trial to evaluate the steroidal aromatase inhibitor exemestane as extended adjuvant therapy in this setting. Patients and Methods Postmenopausal patients with clinical T 1-3 N 1 M 0 breast cancer who were disease free after 5 years of tamoxifen were randomly assigned to 5 years of exemestane (25 mg/d orally) or 5 years of placebo. Our primary aim was to test whether exemestane prolongs disease-free survival (DFS). In October 2003, results of National Cancer Institute of Canada (NCIC) MA.17 showing benefit from adjuvant letrozole in this setting necessitated termination of accrual to B-33, unblinding, and offering of exemestane to patients in the placebo group. Results At the time of unblinding, 1,598 patients had been randomly assigned; 72% in the exemestane group continued on exemestane and 44% in the placebo group elected to receive exemestane. With 30 months of median follow-up, original exemestane assignment resulted in a borderline statistically significant improvement in 4-year DFS (91% v 89%; relative risk [RR] = 0.68; P = .07) and in a statistically significant improvement in 4-year relapse-free survival (RFS; 96% v 94%; RR = 0.44; P = .004). Toxicity, assessed up to time of unblinding, was acceptable for the adjuvant setting. Conclusion Despite premature closure and crossover to exemestane by a substantial proportion of patients, original exemestane assignment resulted in non–statistically significant improvement in DFS and in statistically significant improvement in RFS.

    Abstract: Patient-reported outcome measures (PROMs) that assess how patients feel and function have potential for evaluating quality of care. Stakeholder recommendations for PRO-based performance measures (PMs) were elicited, and feasibility testing was conducted at six cancer centers. METHODS: Interviews were conducted with 124 stakeholders to determine priority symptoms and risk adjustment variables for PRO-PMs and perceived acceptability. Stakeholders included patients and advocates, caregivers, clinicians, administrators, and thought leaders. Feasibility testing was conducted in six cancer centers. Patients completed PROMs at home 5-15 days into a chemotherapy cycle. Feasibility was operationalized as ≥ 75% completed PROMs and ≥ 75% patient acceptability. RESULTS: Stakeholder priority PRO-PMs for systemic therapy were GI symptoms (diarrhea, constipation, nausea, vomiting), depression/anxiety, pain, insomnia, fatigue, dyspnea, physical function, and neuropathy. Recommended risk adjusters included demographics, insurance type, cancer type, comorbidities, emetic risk, and difficulty paying bills. In feasibility testing, 653 patients enrolled (approximately 110 per site), and 607 (93%) completed PROMs, which indicated high feasibility for home collection. The majority of patients (470 of 607; 77%) completed PROMs without a reminder call, and 137 (23%) of 607 completed them after a reminder call. Most patients (72%) completed PROMs through web, 17% paper, or 2% interactive voice response (automated call that verbally asked patient questions). For acceptability, 〉 95% of patients found PROM items to be easy to understand and complete. CONCLUSION: Clinicians, patients, and other stakeholders agree that PMs that are based on how patients feel and function would be an important addition to quality measurement. This study also shows that PRO-PMs can be feasibly captured at home during systemic therapy and are acceptable to patients. PRO-PMs may add value to the portfolio of PMs as oncology transitions from fee-for-service payment models to performance-based care that emphasizes outcome measures.

    Abstract: To update the 2000 American Society of Clinical Oncology guideline on the use of hematopoietic colony-stimulating factors (CSF). Update Methodology The Update Committee completed a review and analysis of pertinent data published from 1999 through September 2005. Guided by the 1996 ASCO clinical outcomes criteria, the Update Committee formulated recommendations based on improvements in survival, quality of life, toxicity reduction and cost-effectiveness. Recommendations The 2005 Update Committee agreed unanimously that reduction in febrile neutropenia (FN) is an important clinical outcome that justifies the use of CSFs, regardless of impact on other factors, when the risk of FN is approximately 20% and no other equally effective regimen that does not require CSFs is available. Primary prophylaxis is recommended for the prevention of FN in patients who are at high risk based on age, medical history, disease characteristics, and myelotoxicity of the chemotherapy regimen. CSF use allows a modest to moderate increase in dose-density and/or dose-intensity of chemotherapy regimens. Dose-dense regimens should only be used within an appropriately designed clinical trial or if supported by convincing efficacy data. Prophylactic CSF for patients with diffuse aggressive lymphoma aged 65 years and older treated with curative chemotherapy (CHOP or more aggressive regimens) should be given to reduce the incidence of FN and infections. Current recommendations for the management of patients exposed to lethal doses of total body radiotherapy, but not doses high enough to lead to certain death due to injury to other organs, includes the prompt administration of CSF or pegylated G-CSF.

    Abstract: 7003 Background: Gilteritinib, a highly selective FLT3/AXL inhibitor, has displayed antileukemic activity in FLT3 mutation-positive (FLT3 mut+ ) relapsed/refractory (R/R) AML in the CHRYSALIS Phase I/II study (NCT02014558), specifically at doses ≥80 mg/d. This exploratory analysis assessed molecular response to gilteritinib in a CHRYSALIS subpopulation. Methods: Molecular response was assessed from bone marrow aspirates obtained at baseline and at ≥1 additional time point from FLT3 mut+ patients (≥18 y) treated with 120 or 200 mg/d gilteritinib. These doses were identified due to their ability to induce consistent, potent FLT3 inhibition and high clinical response rates. FLT3-ITD and total FLT3 were quantified by NGS to assess molecular response. A Cox regression model of overall survival (OS) by Kaplan-Meier estimation established a FLT3-ITD:total FLT3 ratio (ITD signal ratio) of 10 −2 as the threshold for improved survival. Results: Of 147 FLT3-ITD mut+ patients who received gilteritinib 120 or 200 mg/d, 80 were included in this analysis. Composite response rate for these 80 patients was 55%. During response, 20 patients (25%) had an ITD signal ratio of ≤10 −2 . Of these 20 patients, 18 had a ratio of ≤10 −3 (major molecular response [MMR]) and 13 had a ratio of ≤10 −4 (minimal residual disease [MRD] negative). Median time to achieve minimum signal ratio was 54 days. Elimination of morphologic leukemia was observed in 80% of patients with ITD signal ratios 〈 10 −2 . Patients who had a signal ratio ≤10 −2 , MMR, or were MRD negative had significantly longer median OS than those who did not (Table). Conclusions: Molecular responses to gilteritinib in FLT3-ITD mut+ R/R AML correlated with clinical response and improved OS. This is the first demonstration of molecular response to a FLT3 inhibitor in AML. These data suggest ITD signal ratio may predict durable clinical benefit of gilteritinib.

    Abstract: Treatment-related stomach cancer is an important cause of morbidity and mortality among the growing number of Hodgkin lymphoma (HL) survivors, but risks associated with specific HL treatments are unclear. Patients and Methods We conducted an international case-control study of stomach cancer nested in a cohort of 19,882 HL survivors diagnosed from 1953 to 2003, including 89 cases and 190 matched controls. For each patient, we quantified cumulative doses of specific alkylating agents (AAs) and reconstructed radiation dose to the stomach tumor location. Results Stomach cancer risk increased with increasing radiation dose to the stomach (P trend 〈 .001) and with increasing number of AA-containing chemotherapy cycles (P trend = .02). Patients who received both radiation to the stomach ≥ 25 Gy and high-dose procarbazine (≥ 5,600 mg/m 2 ) had strikingly elevated stomach cancer risk (25 cases, two controls; odds ratio [OR], 77.5; 95% CI, 14.7 to 1452) compared with those who received radiation 〈 25 Gy and procarbazine 〈 5,600 mg/m 2 (P interaction 〈 .001). Risk was also elevated (OR, 2.8; 95% CI, 1.3 to 6.4) among patients who received radiation to the stomach ≥ 25 Gy but procarbazine 〈 5,600 mg/m 2 ; however, no procarbazine-related risk was evident with radiation 〈 25 Gy. Treatment with dacarbazine also increased stomach cancer risk (12 cases, nine controls; OR, 8.8; 95% CI, 2.1 to 46.6), after adjustment for radiation and procarbazine doses. Conclusion Patients with HL who received subdiaphragmatic radiotherapy had dose-dependent increased risk of stomach cancer, with marked risks for patients who also received chemotherapy containing high-dose procarbazine. For current patients, risks and benefits of exposure to both procarbazine and subdiaphragmatic radiotherapy should be weighed carefully. For patients treated previously, GI symptoms should be evaluated promptly.

    Abstract: e20004 Background: IB is a Bruton’s tyrosine kinase inhibitor that showed superior progression-free survival compared with BR in CLL patients (pts) 65 years or older in a randomized phase 3 trial (Woyach et al, NEJM 2018). Pts receiving IB had higher rates of atrial fibrillation (AFIB) and hypertension (HTN); BR pts had higher rates of hematologic toxicity. Differences in treatment duration for BR (6 cycles) and IB (until progression) complicated adverse event (AE) comparisons. Here we use an exploratory approach to compare toxicity burden between arms and provide assessment of AFIB, HTN and infections (INF). Methods: AEs were reported for each of cycles 1-6 and then every 3 cycles until progression or nonprotocol CLL therapy. Only grade (gr) 3-4 AEs were reported thereafter until death. A simple global AE score was calculated for each pt by summing grades of all gr 1-4 AEs and dividing by the number of cycles over which AEs were submitted. Results: 537 pts began therapy (176 BR, 361 IB). 68% on BR completed all 6 cycles. At a median follow-up of 38 months, 64% remained on IB. Treatment discontinuation for AE occurred in 10% and 14% of BR and IB pts. Overall, median AE score was 1.8 (interquartile range (IQR) 0.9-3.3) and 3.8 (IQR 2.3-5.9) in BR and IB arms (p 〈 0.01). For cycles 1-6, median AE score was 6.2 (IQR 3.8-9.0) and 4.8 (IQR 3.0-7.2) in BR and IB arms (p 〈 0.01). In the IB arm, median AE score post 6 cycles decreased significantly to 3.4 (IQR 1.9-5.6) (p 〈 0.01). Gr 3 or higher cumulative rates of AFIB, HTN, and INF over time appear in the table. 100 pts (26/176 BR, 74/361 IB) had 137 severe INF (39% respiratory: 16 BR, 37 IB; 25% skin: 3 BR, 31 IB; 12% GU: 3 BR, 13 IB; 25% other: 12 BR, 22 IB). There were 7 gr 5 INF (3 BR, 4 IB), none confirmed fungal. Conclusions: There was no difference in treatment discontinuation rates for AE. Overall toxicity burden was significantly higher for IB, although IB toxicity burden decreased after 6 cycles. Toxicity burden was significantly higher in cycles 1-6 for pts receiving BR. Risk of severe AFIB, HTN, and INF is highest in the first year of IB. A simple AE score provides valuable information, especially when evaluating regimens of varying length.

    Abstract: 587 Background: Few markers reliably identify colorectal cancer (CRC) patients at risk of recurrence and death. SMAD4 loss occurs in 10-20% of cases and has shown promise in identifying high-risk stage II/III patients. We examined SMAD4 status and association with clinical/pathologic features in 446 stage I-IV CRC patients at Memorial Sloan Kettering (MSK). Methods: Patients undergoing curative resection were included (1981-2010). Familial polyposis syndrome patients and those with inadequate tissue were excluded. Tissue microarrays were constructed (n=364). Immunohistochemistry for SMAD4 and mismatch repair (MMR) proteins was completed. SMAD4 nuclear stain intensity was scored (scale=0-3; 0=loss). On whole sections, MMR proteins (present or absent), tumor-infiltrating lymphocytes (TILs) and peritumoral lymphocyte aggregates (PLAs) were scored (scale=0-3). Associations between clinical/pathologic features and SMAD4 loss vs. retention were analyzed. Kaplan-Meier estimates and log-rank test were used for recurrence-free and overall survival analyses (RFS and OS). Results: SMAD4 loss was noted in 13%. Median age at diagnosis was 53 years, and 51% were male. The cohort consisted of 61% hindgut tumors and 62% stage II/III patients. With up to 33 years of follow-up, the mean was 6 years. SMAD4 loss correlated with higher tumor and nodal stage, adjuvant therapy use, and lower TIL and PLA scores (p 〈 0.04 for all). Unlike prior studies, no significant differences in OS based on SMAD4 status across the entire cohort were noted; however, older patients ( 〉 median) were noted to have worse OS with SMAD4 loss (p 〈 0.01). SMAD4 loss did correlate with worse RFS (p=0.02), persisting even when excluding MMR-deficient patients. Additionally, SMAD4 loss was associated with worse RFS in both the adjuvant chemotherapy group (median RFS=3.8 vs. 13 years; p=0.06) and the resection-only group (median RFS=4.2 years vs. not yet reached; p 〈 0.01). Conclusions: SMAD4 loss correlates with worse RFS and resistance to adjuvant therapy. SMAD4 loss also correlates with lower TIL and PLA scores. Future work will address chemoresistance mechanisms, relevance to adjuvant therapy use, and loss of immune infiltrate in SMAD4-null tumors.

    Abstract: 8074 Background: Stage IV NSCLC patients who progress through first-line therapy have poor progression-free survival (PFS) and overall survival (OS), most commonly failing in existing sites of gross disease after systemic therapy. Cytoreduction with SBRT may aid systemic agents in prolonging survival. We decided to test this hypothesis in a multi-institutional phase II study with SBRT and erlotinib. Methods: Stage IV NSCLC patients with ≤ 6 sites of extracranial disease who failed first-line systemic therapy were eligible to receive SBRT to all sites of clinically apparent disease, utilizing equipotent fractionation schemes based on location of disease and risk of toxicity to critical normal structures, and erlotinib given daily (150 mg OD) until disease progression. Frequent SBRT fractionation schemes used included 33 Gy in 11 Gy fractions and 40 Gy in 8 Gy fractions. Safety and clinical endpoints were evaluated. Results: 23 patients (12 M: 11 F) with a median age of 67 (56-86) were enrolled in this trial with median follow-up of 14.7 months. All patients progressed through platinum-based chemotherapy, 14 with paclitaxel and 7 with pemetrexed as part of the doublet regimen. 20/23 patients received SBRT to 3 or fewer sites. Lung parenchyma and mediastinal lymph nodes represented most common sites of irradiation. Median PFS was 10.7 months and median OS was 20.8 months.A majority of patients progressed in new sites with only 4 patients failing locally. Most distant failures manifested in the liver. Only one grade 3 toxicity, pneumonitis, was radiation-related. The trial commenced before molecular profiling became standard; 5/10 patient tumors tested, however, had EGFR alterations by IHC/FISH, 0/10 were positive for an EGFR mutation. Conclusions: Use of SBRT with erlotinib for unselected stage IV NSCLC patients as a second-line therapy was well tolerated and resulted in significant PFS and OS, substantially greater than historical values for patients who only received second-line systemic agents. Debulking gross disease with local therapy results in a median PFS of nearly a year with patients relapsing most commonly in new rather than existing sites. Clinical trial information: NCT00547105.
