17520 Background: Extramedullary relapse (EMR) is a rare event in APL and reports have suggested a possible rol of ATRA in its pathogenesis. Our study intent to determine the pattern of EMR in Latin patients treated whit trans-retinoic acid (ATRA) and chemotherapy (CT). Methods: We evaluated 87 patients diagnosed of APL from January 2001 to December 2005. They were treated with ATRA and chemotherapy. Results: 74/87 received ATRA plus chemotherapy. Median age was 28 (5–68). 39/74 (53%) patients were female. Subtype M3v constituted 21/74 (28%). 76% presented disseminated intravascular coagulation (DIC). Extramedullary deposit was observed in 7 cases, more frequent was central nervous system (CNS). According the Sanz Index, 32/74 (32%) were High Risk, 40/74 (54%) Intermediate Risk, 2 Low Risk. 31/55 (56%) presented t(15,17). 52/74 (70%) patients had complete response. EMR was documented in 8 (15%) (CNS: 5, External Auditory Foramen: 3), 4 were High Risk. Median time to EMR was 11.5 months (7.03–27.3). 55% are alive at date. The following median was 36 months, 41 months of Disease Free Survival (DFS), rate was 62 % to 3 years. Overall survival was 44 months; rate was 83% to 3 years. Conclusions: EMR incidence was 8%, higher report that other series, this event was presented in CNS and external auditory foramen. It suggest to establish EMR risk factors and to include CNS prophylactic treatment. No significant financial relationships to disclose.

Abstract Few studies have examined the outcome of large numbers of patients with the microgranular variant (M3V) of acute promyelocytic leukemia (APL) in the all-trans retinoic acid era. Here, the outcome of 155 patients treated with all-trans retinoic acid–based therapy on 3 clinical trials, North American Intergroup protocol I0129 and Programa para el Estudio de la Terapéutica en Hemopatía Maligna protocols LPA96 and LPA99, are reported. The complete remission rate for all 155 patients was 82%, compared with 89% for 748 patients with classical M3 disease. The incidence of the APL differentiation syndrome was 26%, compared with 25% for classical M3 patients, and the early death rate was 13.6% compared with 8.4% for patients with classical M3 morphology. With a median follow-up time among survivors of 7.6 years (range 3.6-14.5), the 5-year overall survival, disease-free survival, and cumulative incidence of relapse for patients with M3V were 70%, 73%, and 24%, respectively. With a median follow-up time among survivors of 7.6 years (range 0.6-14.3), the 5-year overall survival, disease-free survival, and cumulative incidence of relapse among patients with classical M3 morphology were 80% (P = .006 compared with M3V), 81% (P = .07), and 15% (P = .005), respectively. When outcomes were adjusted for the white blood cell count or the relapse risk score, none of these outcomes were significantly different between patients with M3V and classical M3 APL.

Purpose To compare patients with high-risk stage III to IV Hodgkin lymphoma (HL) in the phase III European Organisation for Research and Treatment of Cancer 20012 Intergroup trial (Comparison of Two Combination Chemotherapy Regimens in Treating Patients With Stage III or Stage IV Hodgkin’s Lymphoma) who were randomly assigned to either doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or to bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP). Patients and Methods Patients with clinical stage III or IV HL, International Prognostic Score of 3 or higher, and age 60 years or younger received ABVD for eight cycles (ABVD8) or escalated-dose BEACOPP (BEACOPPescalated) for four cycles followed by baseline BEACOPP (BEACOPPbaseline) for four cycles (BEACOPP4+4) without radiotherapy. Primary end points were event-free survival (EFS), treatment discontinuation, no complete response (CR) or unconfirmed complete response (CRu) after eight cycles, progression, relapse, or death. Secondary end points were CR rate, overall survival (OS), quality of life, secondary malignancies, and disease-free survival in CR/CRu patients. Results Between 2002 and 2010, 549 patients were randomly assigned to ABVD8 (n = 275) or BEACOPP4+4 (n = 274). Other characteristics included median age, 35 years; male, 75%; stage IV, 74%; “B” symptoms, 81%; and International Prognostic Score ≥ 4, 59%. WHO performance status was 0 (34%), 1 (48%), or 2 (17%). Median follow-up was 3.6 years. CR/CRu was 82.5% in both arms. At 4 years, EFS was 63.7% for ABVD8 versus 69.3% for BEACOPP4+4 (hazard ratio [HR], 0.86; 95% CI, 0.64 to 1.15; P = .312); disease-free survival was 85.8% versus 91.0% (HR, 0.59; 95% CI, 0.33 to 1.06; P = .076), and OS was 86.7% versus 90.3% (HR, 0.71; 95% CI, 0.42 to 1.21; P = .208). Death as a result of toxicity occurred in six and five patients, early discontinuation (before cycle 5) in 12 and 26 patients, treatment crossovers in five and 10 patients, and secondary malignancies in eight and 10 patients in the ABVD8 and BEACOPP4+4 arms, respectively. Conclusion ABVD8 and BEACOPP4+4 resulted in similar EFS and OS in patients with high-risk advanced-stage HL. Because BEACOPP4+4 did not demonstrate a favorable effectiveness or toxicity ratio compared with ABVD8, treatment burden, immediate and late toxicities, and associated costs must be considered before selecting one of these regimens on which to build future treatment strategies.

Abstract Background Currently, there is no reliable blood-based marker to track tumor recurrence in endometrial cancer (EC) patients. Liquid biopsies, specifically, circulating tumor DNA (ctDNA) analysis emerged as a way to monitor tumor metastasis. The objective of this study was to examine the feasibility of ctDNA in recurrence surveillance and prognostic evaluation of high-risk EC. Methods Tumor tissues from nine high-risk EC patients were collected during primary surgery and tumor DNA was subjected to next generation sequencing to obtain the initial mutation spectrum using a 78 cancer-associated gene panel. Baseline and serial post-operative plasma samples were collected and droplet digital PCR (ddPCR) assays for patient-specific mutations were developed to track the mutations in the ctDNA in serial plasma samples. Log-rank test was used to assess the association between detection of ctDNA before or after surgery and disease-free survival. Results Somatic mutations were identified in all of the cases. The most frequent mutated genes were PTEN, FAT4, ARID1A, TP53, ZFHX3, ATM, and FBXW7. For each patient, personalized ddPCR assays were designed for one-to-three high-frequent mutations. DdPCR analysis and tumor panel sequencing had a high level of agreement in the assessment of the mutant allele fractions in baseline tumor tissue DNA. CtDNA was detected in 67% (6 of 9) of baseline plasma samples, which was not predictive of disease-free survival (DFS). CtDNA was detected in serial post-operative plasma samples (ctDNA tracking) of 44% (4 of 9) of the patients, which predicted tumor relapse. The DFS was a median of 9 months (ctDNA detected) versus median DFS undefined (ctDNA not detected), with a hazard ratio of 17.43 (95% CI, 1.616–188.3). The sensitivity of post-operative ctDNA detection in estimating tumor relapse was 100% and specificity was 83.3%, which was superior to CA125 or HE4. Conclusions Personalized ctDNA detection was effective and stable for high-risk EC. CtDNA tracking in post-operative plasma is valuable for predicting tumor recurrence.

Background There is no standard adjuvant chemotherapy to prevent recurrent cholangiocarcinoma (CCA), a rare cancer with poor prognosis. We assessed the efficacy and safety of GEMOX on intrahepatic and hilar CCA with high-risk factors after curative surgery. Patients and Methods Twenty two patients (mean age: 57 years old) with CCA received 6 cycles of GEMOX: gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 on day 2, q3w after a curative surgery. Results All patients completed 6 cycles of GEMOX. EGFR membranous expression was present in 20 CCA. The 5-year survival rate was 56% (CI 95%: 25.7–85.4); 2-year disease free survival rate was 28% (CI 95%: 3.4–52.6). Median time to progression was 15 months. The rate of recurrence after surgery and chemotherapy was 63% (14/22). Two patients died of disease progression. Twelve patients received cetuximab/GEMOX at the time of relapse. Six died after 12 months (9–48 months), three are still alive suggesting a clinical applicability of EGFR inhibitors in CCA. Conclusion Adjuvant chemotherapy with GEMOX alone seems ineffective in intrahepatic and hilar CCA with a high risk of relapse. Additional studies including targeted therapies to circumvent such poor chemosensitivity are needed.

The aim of the study: to increase the frequency of achieving pathologic complete response and increase disease-free survival in the investigational group of patients with locally advanced rectal cancer T3(MRF+)–4N0–2M0 by developing a new strategy for neoadjuvant therapy.Materials and methods. In total, 414 patients were assigned to treatment. Control group I included 89 patients who underwent radiotherapy (RT) 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week. Control group II included 160 patients who underwent RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and oxaliplatin once a week, during the course of RT. Study group III consisted of 165 patients. This group combined RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and additional consecutive CapOx cycles. This group was divided into 2 subgroups: subgroup IIIa included 106 patients with consolidating chemotherapy (after CRT); subgroup IIIb included 59 patients who underwent “sandwich” treatment. Therapy consisted of conducting from 1 to 2 cycles of induction CapOx (up to CRT) and from 1 to 2 cycles of consolidating CapOx with an interval of 7 days. In the interval between the courses of drug therapy, RT 52–56 Gy/26–28 fractions was performed. According to the results of the control examination, further treatment tactics were determined. The primary end points were 5-year disease-free survival and the achievement of a pathologic complete response.Results. Pathologic complete response was significantly more often recorded in patients in the investigational group III (17.48 %; p = 0.021) compared with control groups (7.95 % in the I group and 8.28 % in the II group). 5-year disease-free survival in patients in the study groups was: 71.5 % in the III group, 65.6 % in the II group and 56.9 % in the I group.Conclusion. The shift in emphasis on strengthening the neoadjuvant effect on the tumor and improving approaches to drug therapy regimens have significantly improved disease-free survival of patients with locally advanced rectal cancer.

391 Background: The standard of care (SOC) for patients (pts) with MIUC is radical surgery ± cisplatin-based neoadjuvant chemotherapy (chemo), but many pts are cisplatin-ineligible. There is no conclusive evidence supporting adjuvant chemo in pts who did not receive neoadjuvant chemo and in those with residual disease after neoadjuvant cisplatin. This phase 3 trial of adjuvant nivolumab (NIVO) vs placebo (PBO) in pts with MIUC after radical surgery ± neoadjuvant cisplatin (CheckMate 274) aims to address an unmet need in these pts. We report the initial results. Methods: This is a phase 3, randomized, double-blind, multicenter trial of NIVO vs PBO in pts with high-risk MIUC (bladder, ureter, or renal pelvis) after radical surgery. Pts were randomized 1:1 to NIVO 240 mg Q2W or PBO for ≤ 1 year of adjuvant treatment. Pts had radical surgery within 120 days ± neoadjuvant cisplatin or were ineligible/declined cisplatin-based chemo, evidence of UC at high risk of recurrence per pathologic staging, were disease-free by imaging, and ECOG PS ≤ 1. Primary endpoints: disease-free survival (DFS) in all randomized pts (ITT population) and in pts with tumor PD-L1 expression ≥ 1%. DFS was stratified by nodal status, prior neoadjuvant cisplatin, and PD-L1 status. Non–urothelial tract recurrence-free survival (NUTRFS) in ITT pts and in pts with PD-L ≥ 1% is a secondary endpoint. Safety is an exploratory endpoint. Results: In total, 353 pts were randomized to NIVO (PD-L1 ≥ 1%, n = 140) and 356 pts to PBO (PD-L1 ≥ 1%, n = 142). The primary endpoint of DFS was met in ITT pts (median follow-up, 20.9 mo for NIVO; 19.5 mo for PBO) and in pts with PD-L1 ≥ 1%. DFS and NUTRFS were improved with NIVO vs PBO in both populations (Table). DFS improvement with NIVO was generally consistent across subgroups. Grade 3–4 treatment-related adverse events (TRAEs) occurred in 17.9% and 7.2% of pts in the NIVO and PBO arms, respectively. Conclusions: NIVO demonstrated a statistically significant and clinically meaningful improvement in DFS vs PBO for MIUC after radical surgery, both in ITT pts and pts with PD-L1 ≥ 1%. AEs were manageable and consistent with previous reports. These results support adjuvant NIVO as a new SOC for pts with MIUC with high risk for recurrence despite neoadjuvant chemo or those ineligible for and/or declining cisplatin-based chemo.

PURPOSE Radiotherapy (RT) plus long-term androgen suppression (AS) are a standard treatment option for patients with high-risk localized prostate cancer. We hypothesized that docetaxel chemotherapy (CT) could improve overall survival (OS) and clinical outcomes among patients with high-risk prostate cancer. PATIENTS AND METHODS The multicenter randomized NRG Oncology RTOG 0521 study enrolled patients with high-risk nonmetastatic disease between 2005 and 2009. Patients were randomly assigned to receive standard long-term AS plus RT with or without adjuvant CT. RESULTS A total of 612 patients were enrolled; 563 were evaluable. Median prostate-specific antigen was 15.1 ng/mL; 53% had a Gleason score 9 to 10 cancer; 27% had cT3 to cT4 disease. Median follow-up was 5.7 years. Treatment was well tolerated in both arms. Four-year OS rate was 89% (95% CI, 84% to 92%) for AS + RT and 93% (95% CI, 90% to 96%) for AS + RT + CT (hazard ratio [HR], 0.69; 90% CI, 0.49 to 0.97; one-sided P = .034). There were 59 deaths in the AS + RT arm and 43 in the AS + RT + CT arm, with fewer deaths resulting from prostate cancer in the AS + RT + CT arm versus AS + RT (23 v 16 deaths, respectively). Six-year rate of distant metastasis was 14% for AS + RT and 9.1% for AS + RT + CT, (HR, 0.60; 95% CI, 0.37 to 0.99; two-sided P = .044). Six-year disease-free survival rate was 55% for AS + RT and 65% for AS + RT + CT (HR, 0.76; 95% CI, 0.58 to 0.99; two-sided P = .043). CONCLUSION For patients with high-risk nonmetastatic prostate cancer, CT with docetaxel improved OS from 89% to 93% at 4 years, with improved disease-free survival and reduction in the rate of distant metastasis. The trial suggests that docetaxel CT may be an option to be discussed with selected men with high-risk prostate cancer.
