326 Background: Improved safety and response rates of AMVAC over standard MVAC in patients (pts) with metastatic bladder cancer support study of neoadjuvant AMVAC for pts with muscle invasive bladder cancer (MIBC) and prenephroureterectomy (NU) for pts with high-grade upper-tract urothelial cancer (UTUC). We performed a phase II study of neoadjuvant AMVAC in MIBC and UTUC, and herein report the results of the UTUC exploratory subgroup. Methods: Pts with UTUC (ureter or renal pelvis) with high-grade UC on biopsy, or positive urine cytology and mass on cross sectional imaging, N0-N1, CrCl >=50, adequate hepatic and marrow function were eligible. Pts received 3 cycles of AMVAC (methotrexate 30 mg/m2, vinblastine 3 mg/m2, doxorubicin 30 mg/m2, cisplatin 70mg/m2) day 1, pegfilgrastim 6 mg day 2 or 3, every 2 weeks. NU, with lymph node dissection at surgeon discretion, was performed 4-8 weeks after last cycle. Exploratory endpoint was pathologic complete response (pCR) rate. Results: Accrual is complete with 10 evaluable UTUC pts enrolled at 2 institutions (FCCC, TJU) over 46.5 months. Median age 67 (range 49-83). Of 10 pts, 6 completed all 3 cycles of AMVAC. Four pts received < 3 cycles due to grade 3 acute kidney injury (1), pyelonephritis and grade 3 diverticulitis (1), flare of underlying hepatitis (1), grade 3 fatigue (1). Additional related grade 3 adverse events (AE) were anemia (1) and nausea/vomiting (1), no grade 4 or 5 AE. All pts underwent NU within 8 weeks of last chemotherapy, median 5.5 weeks. Median time from day 1 AMVAC to NU was 9 wks. 1/10 pts had a pCR, 4/10 patients were staged <pT1, 2/10 pT2, and 3/10 >pT3 or N+. An additional 21.5 months of enrollment were needed in this expansion cohort to accrue 10 pts with UTUC, compared to 44 MIBC pts in 25 mos. All pts completed study treatment as of July 2013. Conclusions: In this small sample, neoadjuvant AMVAC prior to NU was clinically active with manageable toxicity. With short duration from start of chemotherapy to NU, 3 neoadjuvant AMVAC cycles should be considered for further study for high-grade UTUC prior to NU in the cooperative group setting. Clinical trial information: NCT01031420.

4526 Background: Standard methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) demonstrates a survival benefit in the neoadjuvant setting for patients (pts) with muscle invasive bladder cancer (MIBC). Compared with standard MVAC, AMVAC yielded higher response rates with less toxicity in the metastatic setting. Methods: Pts with MIBC, cT2-T4a, and N0-N1 with CrCl >=50 and adequate hepatic and marrow function were eligible. Pts received 3 cycles of AMVAC (methotrexate 30 mg/m2, vinblastine 3 mg/m2, doxorubicin 30 mg/m2, cisplatin 70mg/m2) on day 1, with pegfilgrastim 6 mg day 2 or 3, every 2 weeks. Pts with CrCl < 60 could receive cisplatin split over 2 days. Radical cystectomy (RC) with lymph node dissection was performed 4-8 weeks after the last dose of chemotherapy. Primary endpoint was pathologic complete response (pCR) rate. Results: Accrual is complete with 44 MIBC pts enrolled at 2 institutions (FCCC, TJU) over a 25 month period. Median age 64 (range 45-83). Three withdrew from study early and are not evaluable for response (2 physician discretion, 1 withdrawal of consent). An additional 8 are currently receiving treatment on study with toxicity and response data pending. Of the 33 evaluable pts for whom final data is available, 30 received all 3 cycles of AMVAC at full dose. Three pts received < 3 cycles due to grade 3 fatigue (1), low platelets (1), and disease progression precluding RC (1). 32/33 pts underwent RC, all within 8 weeks of last chemotherapy. Median time from start of chemotherapy to RC was 9.7 wks (range 4.6-13 wks). 13/33 pts (39.4%, 95% CI, 22.7-56.1%) had a pCR. An additional 3 (9.1%) were downstaged to non muscle invasive disease. For the intent to treat cohort (n=36) 8 pts had grade 3-4 AMVAC related adverse events, the most common being anemia (3), fatigue (3) and neutropenia (2) and overall pCR rate was 36.1%. (95% CI, 20.4-51.8%). All pts will have completed study treatment by April 2012. Final results will be presented. Conclusions: Neoadjuvant AMVAC is well tolerated and preliminary results show a pCR rate similar to that reported for standard 12-week MVAC, suggesting that AMVAC for three cycles (6 weeks) is a safe and efficient alternative.

Abstract Background Radiotherapy may synergize with programmed death 1 (PD-1)/PD-1 ligand (PD-L1) blockade. The purpose of this study was to determine the recommended Phase II dose, safety/tolerability, and preliminary efficacy of combining pembrolizumab, an anti-PD-1 monoclonal antibody, with hypofractionated stereotactic irradiation (HFSRT) and bevacizumab in patients with recurrent high grade gliomas (HGGs). Methods Eligible subjects with recurrent glioblastoma or anaplastic astrocytoma were treated with pembrolizumab (100 or 200 mg based on dose level Q3W) concurrently with HFSRT (30 Gy in 5 fractions) and bevacizumab 10 mg/kg Q2W. Results Thirty two patients were enrolled (bevacizumab naïve, n = 24; bevacizumab resistant, n = 8). The most common treatment-related adverse events (TRAEs) were proteinuria (40.6%), fatigue (25%), increased alanine aminotransferase (25%), and hypertension (25%). TRAEs leading to discontinuation occurred in 1 patient who experienced a grade 3 elevation of aspartate aminotransferase. In the bevacizumab naïve cohort, twenty patients (83%) had a complete response (CR) or partial response (PR). The median overall survival (OS) and progression-free survival (PFS) were 13.45 months (95% CI: 9.46-18.46) and 7.92 months (95% CI: 6.31-12.45), respectively. In the bevacizumab resistant cohort, PR was achieved in 5 patients (62%). Median OS was 9.3 months (95% CI: 8.97-18.86) with a median PFS of 6.54 months (95% CI: 5.95-18.86). The majority of patients (20/26 pts; 77%) had tumor-cell/tumor-microenvironment PD-L1 expression &lt;1%. Conclusions The combination of HFSRT with pembrolizumab and bevacizumab in patients with recurrent HGG is generally safe and well tolerated. These findings merit further investigation of HFSRT with immunotherapy in HGGs.

Purpose: The aim of this work was to investigate the predictive factors for bladder cancer recurrence survival (BCRS) in patients with upper-tract urothelial carcinoma (UTUC). Methods: We selected patients with UTUC who underwent segmental ureterectomy (Su) or nephroureterectomy (Nu) from 2004 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with a history of intravesical therapy for bladder cancer and bladder cancer prior to the diagnosis of UTUC were excluded. We used Kaplan-Meier analysis, log-rank tests, and Cox proportional hazards model to compare overall survival, cancer-specific survival, and BCRS. Results: In a cohort of 1,454 patients, 169 (11.6%) had low-grade tumors and 1,285 (88.4%) had high-grade tumors; 239 (16.4%) underwent Su and 1,215 (83.6%) underwent Nu. We found that T4 grade (hazard ratio [HR] = 6.216; 95% confidence interval [CI], 3.197-12.087) and ureteral tumors (HR = 1.764; 95% CI, 1.173-2.652) were predictors of shorter BCRS, whereas Nu (HR = 0.608; 95% CI, 0.388-0.953) predicted longer BCRS. Five-year BCRS rates were low-grade tumors: 94.1%, high-grade tumors: 85.4% (p = 0.038); plus Su: 82.9%, and Nu: 87.6% (p = 0.016). Conclusions: Use of Su should be more selective for high-grade tumors, as it correlates with shorter BCRS. Tumors located in the ureter are associated with shorter BCRS than those located in the renal pelvis.

The Impact

Purpose One third of patients with triple-negative breast cancer (TNBC) achieve pathologic complete response (pCR) with standard neoadjuvant chemotherapy (NACT). CALGB 40603 (Alliance), a 2 × 2 factorial, open-label, randomized phase II trial, evaluated the impact of adding carboplatin and/or bevacizumab. Patients and Methods Patients (N = 443) with stage II to III TNBC received paclitaxel 80 mg/m2 once per week (wP) for 12 weeks, followed by doxorubicin plus cyclophosphamide once every 2 weeks (ddAC) for four cycles, and were randomly assigned to concurrent carboplatin (area under curve 6) once every 3 weeks for four cycles and/or bevacizumab 10 mg/kg once every 2 weeks for nine cycles. Effects of adding these agents on pCR breast (ypT0/is), pCR breast/axilla (ypT0/isN0), treatment delivery, and toxicities were analyzed. Results Patients assigned to either carboplatin or bevacizumab were less likely to complete wP and ddAC without skipped doses, dose modification, or early discontinuation resulting from toxicity. Grade ≥ 3 neutropenia and thrombocytopenia were more common with carboplatin, as were hypertension, infection, thromboembolic events, bleeding, and postoperative complications with bevacizumab. Employing one-sided P values, addition of either carboplatin (60% v 44%; P = .0018) or bevacizumab (59% v 48%; P = .0089) significantly increased pCR breast, whereas only carboplatin (54% v 41%; P = .0029) significantly raised pCR breast/axilla. More-than-additive interactions between the two agents could not be demonstrated. Conclusion In stage II to III TNBC, addition of either carboplatin or bevacizumab to NACT increased pCR rates, but whether this will improve relapse-free or overall survival is unknown. Given results from recently reported adjuvant trials, further investigation of bevacizumab in this setting is unlikely, but the role of carboplatin could be evaluated in definitive studies, ideally limited to biologically defined patient subsets most likely to benefit from this agent.

10622 Background: NSABP B-18 randomized women with operable breast cancer to receive chemotherapy either pre- or postoperatively; OS and DSF rates at 9 years were identical. Importantly, pathologic complete response (pCR) was directly proportional to DFS and OS. Recently, dose dense adjuvant chemotherapy has shown a statistically significant improvement in DFS and OS. However, no data is available for the use of dose dense preoperative chemotherapy at this time. Methods: Women enrolled in the I-SPY correlative trial with newly diagnosed breast cancer, T ≥ 3cm, any N, M0 were evaluated to assess response rates and safety to dose dense neoadjuvant chemotherapy (doxorubicin 60 mg/m2 IV Q2 wks × 4, paclitaxel 175 mg/m2 IV Q2 wks × 4, and cyclophosphamide 600 mg/m2 IV Q2 wks × 4). Results: Since 02/2003, 43 pts have been treated with dose dense neoadjuvant chemotherapy on the I-SPY trial at UAB (mean age 47.9). 47% of the pts were ER+, 37% were PR+ and 5% were Her2+ by FISH. 2 pts dropped out for personal reasons and 9 pts are actively undergoing treatment. Overall, 32 pts received dose dense chemotherapy and proceeded to surgery. Of those, 31 received dose dense sequential ATC and 1 received dose dense concurrent AC followed by T. 34% had a pCR (breast & nodes) while an additional 10% had a pCR in the breast but residual disease in lymph nodes; 41% had a PR; 9% had SD; and 6% had PD. Hematologic toxicity consisted of grade 3 anemia in 2 pts, febrile neutropenia in 2 pts and no grade 4 thrombocytopenia. Non-hematologic grade 3–4 toxicity consisted of mediport-associated thrombosis in 2 pts, hyperglycemia in 2 pts, syncope in 1 pt, neuropathy in 1 pt, and disseminated varicella in 1 pt. Conclusion: Our results show that dose dense neoadjuvant chemotherapy achieves a pCR (breast & nodes) in about 1/3 of patients (34%) with tolerable toxicity.

15093 Background: EC is a highly lethal disease with 5 year survival less than 15%. Surgery offers a chance for cure in early disease. Still, fewer than 20% of pts treated with surgery alone are alive at 5 years. Neoadjuvant chemoradiation offers the theoretical advantage of increasing R0 resections and reducing early local and distal metastases which may translate into improved survival. Several clinical trials have resulted in pathologic complete response (pCR) rates of 20–30%. Methods: Newly diagnosed pts with EC Stage 2A (T3) to 4 received weekly Docetaxel (D)25–30mg/m2 and Cisplatin (C)25–30mg/m2.for 6–8 weeks concurrently with radiation, 5040 cGy in 28 fractions. Cetuximab (E) 200mg/m2 was added after it became accepted treatment in head and neck cancers. Pts were scheduled 4 - 6 weeks later for surgery followed by the same chemotherapy for total of 16 weeks of treatment. Pts were assessed for time to progression, overall survival and toxicities. Results: Fifteen pts treated in 2005–6 underwent IRB approved evaluation; 11 male and 4 female, median age of 62(range 44–78) . Four had squamous cell (SCC) and 11 adenocarcinomas. Nine pts had Stage II, 4 pts stage III and 2 pts stage IV disease. Seven pts underwent surgery, all R0 resections. Four of them had pCR, one pPR (downstaged from T3 to T1) and two pts had stable disease. An additional 3 pts had radiological and endoscopic proven CR (medically not surgical candidates) for an objective response (CR+PR) in 8 out of 15 pts (3 SCC and 5 adenoca). Five out of 9 receiving DC had an objective response while 3 of 6 receiving DCE responded. Five pts progressed prior to surgery. Grade 3/4 neutropenia occurred in 2, nausea in 3, and 1 pt experienced Grade 3 dehydration. Four patients required dose reductions by 20%. Six patients had one cycle and 2 had 3 cycles delayed by one week each. Conclusions: Neoadjuvant chemoradiation treatment with weekly Docetaxel and Cisplatin ± Cetuximab is tolerable with high rate of CRs. There was no observed difference in response with the addition of cetuximab. A Phase III study is suggested. No significant financial relationships to disclose.

e16135 Background: Treatment of bladder cancer in elderly patients is a challenging problem because surgery is often not tolerable and the combination of extensive radiotherapy with chemotherapy is also difficult because of patients’ compliance and associated comorbidities. Our study evaluated concurrent radiochemotherapy in elderly patients with locally advanced bladder cancer (T2-T4) in terms of efficacy and tolerability. Methods: Between January 2005 and December 2007, we treated 34 patients with transitional carcinoma of the bladder, with or without nodal involvement, no distant metastases, and median age 79 years (range 66 - 89 years). Their performance status was 0–1-2 in 10–16–8 patients respectively. Cardiovascular comorbidities were the most common (15 patients). The treatment consisted in conformal radiotherapy (mean irradiation dose = 56.4 Gy) concomitant with biweekly Gemcitabine 200 mg/sqm starting on day 1 of radiotherapy. Results: Response was assessed at 4–6 weeks after the end of treatment by cystoscopy with biopsies and MRI. All the patients could end the intended radiation therapy but four of them could not tolerate all the chemotherapy. 13 patients achieved complete response, 12 patients - partial response and 9 patients stable disease. The most common toxicities were: diarrhea (grade 1–2 in 11 patients, grade 3–6 patients), cystitis (grade 1–2 in 5 patients), leucopenia (grade 1–2 in 12 patients, grade 3–4 in 2 patients), thrombocytopenia (grade 1–2 in 6 patients) and anemia (grade 1–2 in 4 patients). Three patient required hospitalization for dehydration and two for febrile neutropenia. After a median follow-up time of 17.4 months, there were 7 relapses and 5 distant metastases. One-year survival rate was 82.41% (28 patients). 6 patients died, 3 from their cancer and 3 from comorbidities. Conclusions: Chemoradiation is well enough tolerated even in elderly patients and also an efficient and organ sparing therapeutic alternative for patients over 65 years old. The treatment choice was based on patients’ preference considering better quality of life with bladder preservation. The use of age-specific therapy adjustments has shown that aggressive treatment for bladder cancer is associated with improved survival even in elderly patients.

1045 Background: High risk BrCa patients (pts) often receive weekly paclitaxel (wP) as well as ddAC. Switching to wA(Abraxane) or adding B or Cb may enhance its efficacy, especially in TN pts. Methods: Pts with clinical stage IIA-IIIC BrCa received wA 100 mg/m2, Cb AUC 6 + B 15 mg/kg q3wks x 12 wks only (cohort 1/Yale) or followed by ddAC + B x 4 (cohort 2/Brown). Endpoints: pathologic complete response (pCR) - absence of invasive BrCa in breast + axillary nodes, residual cancer burden (RCB), clinical CR/partial response (cCR/cPR), and toxicity. Correlative studies are being performed on biopsies obtained at baseline and after run-in doses of wA or B only. Post-op pts resume B for 34 wks; other systemic therapy, including ddAC in cohort 1, is at MD discretion. Results: 55 of 60 pts (median age 47, range 25-68; 31 HR+/29 TN) are evaluable for response (see table below). Median # doses wA 11,Cb 4, ddAC 4. Dose reductions: wA 25% for neutropenia (ANC), Cb 15% for thrombocytopenia (tcp). B 7% held for hypertension. Grade 3-4 toxicities (>5%): ANC 85%, tcp 35%, anemia 25%. Serious adverse events during wA: 3 nausea/dehydration (N/D), 3 infection w/o neutropenic fever (FN), 2 GI bleed; during ddAC: 6 (21%) FN despite G-CSF, 3 N/D. Conclusions: The combination of wA, q3wk Cb + B was well tolerated, with cCR+cPR 84%. However, overall pCR was only 11% (27% in TN) after 12 wks of this regimen (cohort 1). Subsequent preop ddAC raised overall pCR to 54%, and 81% in TN, demonstrating that longer treatment duration or inclusion of anthracycline-based therapy improves responses. Results for cohort 2 compare favorably with those from I-SPY, GeparQuinto and NSABP B-40; the addition of Cb and/or B in TN is being evaluated in CALGB 40603. [Table: see text]

e11550 Background: Triple negative (ER negative, PR negative and HER 2 negative) breast cancers (TNBC) lack effective targeted therapy. We sought to determine the benefit of metronomic neoadjuvant chemotherapy utilizing doxorubicin with cyclophosphamide followed by paclitaxel with carboplatin in women with TNBC. Methods: Patients (pts) with TNBC>2cm were eligible (including locally advanced or inflammatory breast cancer). Pretreatment sentinel node biopsy (SLNB) was performed in patients with clinically N0 disease. Treatment consisted of weekly doxorubicin 24 mg/m2 + daily oral cyclophosphamide 60 mg/m2 x 12 weeks followed by weekly paclitaxel 80 mg/m2 + weekly carboplatin AUC 2 x 12 weeks. Granulocyte colony stimulating factor was added for ANC<= 1000. Pts received standard surgery and radiation therapy as indicated. The primary endpoint was pathologic response. Results: Between 2006 and 2011, 17 pts with infiltrating ductal TNBC were enrolled and 15 were analyzed. Age ranged from 25 to 83 (mean age 45yrs), primary tumor size ranged from 2cm to 7cm (mean 3.5cm). Three pts presented with inflammatory breast cancer, 4 had clinical N1 disease and 2 had clinical N0 disease that did not receive SLNB. Six pts underwent SLNB; 3 were pN0 and 3 were pN positive. Two pts came off study due to prolonged neutopenia. Three pts died during therapy-one of MI, one of PE and one had progressive pulmonary disease. No deaths were therapy related. Ten pts completed therapy. One experienced grade 3 (G3) thrombocytopenia, five patients had G4 neutropenia and one developed G3 neuropathy. Ten pts had a clinical complete response (cCR), four had a clinical partial response (cPR) and one progressed on therapy. The rate of pathologic complete response (pCR) was 46.6% (40% pCR, 6.6% CR with foci of DCIS). One patient had a 0.7cm focus of residual invasive carcinoma. Positive nodes were identified in 13.3%-one patient who progressed on therapy and one who experienced a cPR. Conclusions: Neoadjuvant metronomic chemotherapy with weekly doxorubicin plus daily oral cyclophosamide followed by weekly paclitaxel plus carboplatin revealed high rates of pCR with toxicities limited to marrow suppression.

502 Background: Neoadjuvant chemotherapy (NAC) and concomitant trastuzumab (T) have produced high pathologic complete response (pCR) rates in HER2+ breast cancers. Z1041 addresses the timing of initiation of T with NAC. Methods: Women with operable HER2+ invasive breast cancer were randomized 1:1 to: FEC → P+T (Arm 1) or P+T → FEC+T (Arm 2) where treatment was administered as 5-FU 500 mg/m2, epirubicin 75 mg/m2 and cyclophosphamide 500 mg/m2 day 1 of a 21-day cycle x 4 (FEC); paclitaxel 80 mg/m2 weekly x 12 and trastuzumab 4 mg/kg once then 2 mg/kg weekly x 11. Eligibility also included: tumor > 2 cm or a positive lymph node and left ventricular ejection fraction > 55%. The primary aim was to compare the pCR rates in the breast (pBCR) between the regimens. Secondary endpoints were pCR rate in the breast and lymph nodes (pBNCR) and safety profile. All pts who began study treatment were included in the analyses. With 128 pts per regimen, a two-sided alpha=0.05 test of proportions would have a 90% chance of detecting a difference of 20% or more in the pBCR rates, when the pBCR rate with the poorer regimen is ≤ 25%. Results: From September 15, 2007 to December 15, 2011, 282 women (Arm 1: 140 pts) were enrolled. Two pts (Arm 1) withdrew without receiving treatment. The two arms were similar in age, stage, and hormone receptor (HR) status (HR neg: 40%). The severe (grade 3+) treatment-related toxicities included: neutropenia (Arm 1: 24.6%; Arm 2: 32.4%), fatigue (Arm 1: 4.3%; Arm 2: 8.5%), and neurosensory problems (Arm 1: 3.6%; Arm 2: 4.9%). The pBCR rate and pBNCR rates (Table) were not found to differ between the two regimens (Fisher’s exact p values: 0.905 and 0.811, respectively). Conclusions: High pCR rates can be achieved with trastuzumab in combination with anthracyclines and taxanes. The pBCR or pBNCR was not different between regimens based on the timing of initiation of trastuzumab. Clinical trial information: NCT00513292. [Table: see text]
