Background Procarbazine, lomustine, and vincristine (pcv) significantly improve survival outcomes in lgg (lowgrade gliomas). Administration of pcv to lgg patients increased tremendously over the past years as it went from 2 patients per year between 2005 and 2012 to 23 patients in 2015 only in our centre. However, serious hematological and non-hematological adverse events may occur. The purpose of this study was to evaluate the toxicity of pcv and its clinical relevance in our practice.Methods We retrospectively reviewed the charts of 57 patients with lgg who received pcv at the Centre hospitalier de l’Université de Montréal between 1 January 2005 and 27 July 2016.Results Procarbazine, lomustine, and vincristine were associated with severe hematological toxicity as clinically significant grade 3 anemia, neutropenia, and thrombocytopenia occurred in 7%, 10%, and 28% of patients, respectively. Other frequent adverse events such as the increase of liver enzymes, cutaneous rash, neurotoxicity, and vomiting occurred in 65%, 26%, 60%, and 40% of patients, respectively. Patients with prophylactic trimethoprim/sulfamethoxazole had more grade 3 hematological toxicity with pcv, especially anemia (p = 0.040) and thrombocytopenia (p = 0.003) but we found no increase in pcv toxicity in patients on concurrent anticonvulsants. Patients with grade 3 neutropenia had a significantly lower survival (median survival 44.0 months vs. 114.0 months, p= 0.001). Patients who were given pcv at diagnosis had more grade 3 anemia than those who received it at subsequent lines of treatment (p = 0.042).Conclusion Procarbazine, lomustine, and vincristine increase survival in lgg but were also associated with major hematologic, hepatic, neurologic, and cutaneous toxicity. Anti-Pneumocystis jiroveci pneumonia (pjp) prophylaxis, but not anticonvulsants, enhances hematologic toxicity.

PURPOSE: Eniluracil (776C85), a potent inactivator of dihydropyrimidine dehydrogenase, allows fluorouracil (5-FU) to be administered orally on a schedule that simulates continuous-infusion 5-FU. The primary objective of this study was to estimate the objective tumor response rate of orally administered eniluracil and 5-FU in the treatment of anthracycline- and taxane-resistant advanced breast cancer. PATIENTS AND METHODS: Patients with anthracycline- and taxane-resistant advanced breast cancer were enrolled onto this open-label, phase II, multicenter study. Patients received orally administered 5-FU 1.0 mg/m2 with eniluracil given in a 10:1 ratio (eniluracil:5-FU) twice daily for the first 28 days of each 35-day cycle. RESULTS: Eighty-four patients were enrolled. Eight partial responses were observed in 84 patients (10%; 95% confidence interval [CI], 4.2% to 17.9%), and 20 patients (24%) had stable disease. The median duration of partial response was 20.1 weeks (95% CI, 12 to 26.7 weeks). The median duration of progression-free survival and overall survival for all patients was 9.9 weeks and 40.4 weeks, respectively. Most adverse events were grade 1 or 2 in intensity. Diarrhea, nausea, malaise/fatigue, vomiting, and mucositis were the most common treatment-related nonhematologic adverse events. The most frequently occurring grade 3 or 4 treatment-related adverse events were malaise/fatigue and diarrhea, occurring in 17% and 7% of patients, respectively. The incidence of grade 3 or 4 hematologic toxicity was low. Grade 3 or 4 hyperbilirubinemia occurred in 17% of patients. CONCLUSION: Eniluracil–5-FU has modest antitumor activity and an acceptable safety profile in anthracycline- and taxane-resistant breast cancer. Treatment was convenient, and patient compliance was high.

Abstract Dasatinib(SPRYCEL®) is a kinase inhibitor active against BCR-ABL and SRC family kinases. A phase I trial of dasatinib has shown CHR and MCyR at total daily doses of 100 mg and 140 mg daily in both BID and once daily (QD) schedule in CML-CP patients (pts). Phase II studies of dasatinib have demonstrated the efficacy and safety of a 70 mg twice daily (BID) dose in CML-CP pts with resistance or intolerance to imatinib. We analyzed safety and adverse events (AE) data in 27 pts with CML (CP), imatinib resistant (85%) or intolerant (15%), who have been treated with dasatinib from May 2006 to July 2007 in a compassionate use in Italy. A possible relationship of AE observed during dasatinib with imatinib toxicity and previous types of treatment was analyzed. Median age was 52 years at diagnosis and 58,6 years at start of dasatinib. Sokal was low in 22%, intermediate in 33%, high in 15%, not available in 30%. The median time from CML diagnosis to enrollment in the compassionate use was 78 months. Imatinib dosage, administered during the previous 3 months, was 400 mg/d in 40% of pts, 400–600 mg/d in 50% and >600 mg/d in 10% . Prior treatment for CML included interferon alpha in 48%, chemotherapy in 18%, nilotinib in 18% of the cases and stem cell transplant (SCT) in 1 case. Additional chromosome anomalies and mutations were observed in 18% and 55% of cases, respectively. Dasatinib was administered 70 mg BID, and dose escalation to 100 mg BID and reduction to 50 mg BID or 40 mg BID were allowed for inadequate response or AE. Hematological toxicity during imatinib treatment was reported in 55% of the cases as first episode, and 30% as second episode; extrahematological toxicity was also 55%. Following dasatinib treatment, 70% of the patients had some degree of hematologic toxicity with 21 events. 95% of these AE occurred in the first 2 months of treatment, with 80% in the first month. A second episode of hematolological toxicity was observed in 26% of the cases between months 2 and 15 (median mo. 5). Overall, neutropenia was observed in 11 patients (grade 4 in 5), thromobocytopenia in 11(grade 3 or less) and anemia in 4(grade 4 in one).13 patients have complained of non. hematological toxicity, with 15 AE with grade >2 occurring in the first 40 days. Further AEs were rare and non clinically relevant. The only grade 4 AE was pulmonary oedema; grade 3 AE were fever, arthralgia, liver toxicity, fluid retention; one grade 2 pleural effusion was reported. 48% of cases reduced dosage, whereas only one increased due to lack of response: this patient is now undergoing an allogeneic SCT One patient died, after stop for fluid retention, because of sepsis. All the other patients are still on therapy with a follow-up ranging from 2 to 15 months (median 6 mo). Hematological toxicity during dasatinib was not related to the number of previous treatments and to the time on imatinib. In conclusion, therapy with dasatinib is generally well tolerated, and side effects are reduced by a correct use and clinical surveillance of the patients; in addition, we found that both hematological and extrahematological toxicities decline with time and are not related to the previous treatment.

Abstract BACKGROUND Temozolomide is an alkylating agent commonly used in treatment of gliomas. While this agent is generally well-tolerated, hematologic toxicity is a known complication with grade 3/4 thrombocytopenia in 4% and grade 3/4 neutropenia in 8% of adults. Recent data in several non-CNS malignancies suggested that patients with germline mutations may carry an increased risk of hematological toxicity in the setting of alkylator chemotherapy. We aimed to investigate if germline mutations in glioma patients are associated with myelotoxicity during alkylating chemotherapy. METHODS In this retrospective single-institution study, we reviewed patients with glioma treated at Memorial Sloan Kettering Cancer Center (MSKCC) who had confirmed germline mutations identified by the institution’s Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT) testing. MSK-IMPACT evaluates DNA for mutations in 76 genes known to be associated with hereditary cancer predisposition. RESULTS In 283 patients with glioma who underwent MSK-IMPACT testing, 16 distinct germline mutations were identified in 40 (14%) individuals. 27 had high-grade and 13 had low-grade glioma. Median age was 47 (range 1–79), 12 patients were women. 30 patients received temozolomide chemotherapy. Of the patients treated, four (13%) developed severe hematologic toxicity. Two cases of grade 3 neutropenia and four cases of grade 3/4 thrombocytopenia were identified. Temozolomide was stopped during radiation therapy for three patients with grade 4 thrombocytopenia or neutropenia, and dose-reduced in one patient with grade 3 thrombocytopenia. In patients who had hematologic toxicity, germline mutations were identified in genes NBN, ATM, EPCAM, and FANCC. NBN, ATM, and FANCC are involved in DNA repair. EPCAM is involved in cell adhesion. CONCLUSIONS Hematologic toxicity is a known complication with alkylator chemotherapy. Germline testing may identify patients at increased risk, leading to closer monitoring, modified dosing regimens to minimize myelosuppression, and quicker intervention to prevent interruptions in treatment.

Introduction Part B of the modified Magrath regimen (ifosfamide, etoposide, and cytarabine; IVAC) with or without rituximab (R) is utilized as a standalone regimen in the management of relapsed/refractory Burkitt lymphoma and other non-Hodgkin lymphomas (NHL). There are no comparative or prospective data and a paucity of retrospective, non-comparative data to support use of this regimen. A small retrospective study described second-line IVAC use without R in a mixed cohort of patients with diffuse large B-cell lymphoma (DLBCL) or peripheral T-cell lymphoma, suggesting utility as a bridge to hematopoietic cell transplantation (HCT) (Pereira J, et al. Leuk Res. 2006 Jun;30(6):681-5). The activity of this regimen in B-cell NHL, particularly in conjunction with R, and its toxicity remain incompletely described. In this study, we describe our institutional experience with IVAC +/- R in relapsed/refractory B-cell NHL. Methods We reviewed all patients with relapsed/refractory B-cell NHL treated with IVAC +/- R between 1 January 2004 and 30 September 2019 at Memorial Sloan Kettering Cancer Center to assess efficacy and toxicity. Patients who received IVAC as part of sequential or alternating chemotherapy were excluded. Standard dosing consisted of ifosfamide 1500mg/m2 IV over 60min days 1-5, etoposide 60mg/m2 IV over 60min days 1-5, cytarabine 2000mg/m2 IV over 3 hours every 12 hours days 1-2, with or without rituximab 375mg/m2 IV day 0 or 1 in 21- to 28-day cycles (Lacasce A, et al. Leuk Lymphoma. 2004 Apr;45(4):761-7). Results Cohort and treatment characteristics are described in Table 1. Among 54 eligible patients (median age 51 years), 76% had DLBCL; 30% had lymphomatous central nervous system involvement at the time of initiating IVAC. Patients had received median 2 prior lines of therapy, with the last dose of the most recent line of therapy administered a median of 3 weeks prior to initiating IVAC. Patients received median 2 cycles of IVAC +/- R; 48% received IVAC-R. Prophylactic antimicrobials with cycle 1 were utilized in 94%. Most patients received herpesvirus- (81%) and Pneumocystis- (80%) directed prophylaxis; broad-spectrum prophylaxis with a fluoroquinolone was less common (24%). Primary granulocyte colony stimulating factor (GCSF) was utilized in 93% of patients with cycle 1; primary or secondary GCSF was utilized in 94% of cycles. Efficacy outcomes are described in Table 1. Objective response rate (ORR) among 46 evaluated patients was 48%; 17% achieved CR. ORR did not vary significantly between patients who did or did not receive R (58% vs 42%; p = 0.5) but was associated with number of IVAC cycles administered (among responders, 69% received 3-4 cycles while 31% received 1-2 cycles; p < 0.001). At median follow-up of 22 months, median progression-free survival (PFS) and overall survival (OS) were 3.1 months and 4.9 months, respectively (Figure). In Cox proportional hazard regression analysis of survival, patients who received R with every cycle (p = 0.025) and received 3 or more cycles (p < 0.001) experienced significantly longer PFS. Patients who achieved CR (p < 0.001) or PR (p = 0.003), received R with every cycle (p < 0.001), received 3 or more cycles (p < 0.001), or underwent subsequent HCT or CAR-T cell therapy (p = 0.001) experienced significantly longer OS. Toxicity outcomes are described in Table 2. Grade ≥ 3 anemia (93%), neutropenia (94%), and thrombocytopenia (100%; all grade 4) were common, regardless of number of cycles received. Febrile neutropenia (FN) occurred in 65% of patients and complicated 47% of cycles; documented infection occurred in 44%. Risk of FN and infection did not appear to be influenced by use of antimicrobial or GCSF prophylaxis. Grade ≥ 3 elevations in AST/ALT or total bilirubin were uncommon (5.6% and 9.3%, respectively). Neurotoxicity attributed to cytarabine or ifosfamide occurred in 17% of patients and was usually low-grade; hemorrhagic cystitis occurred in one patient. In patients for whom cause of death was documented (n = 37), mortality was attributed to a treatment-related complication in 19%. Conclusion IVAC-R may be a useful bridging therapy for patients with relapsed/refractory B-cell NHL who are planned for HCT. However, its potential for profound hematologic toxicity and life-threatening complications despite prophylactic measures requires careful consideration of less toxic alternatives.

Abstract Background The standard chemotherapy regimens for soft tissue sarcoma are doxorubicin-based. This retrospective study aimed to assess the efficacy and safety of pirarubicin, ifosfamide, and etoposide combination therapy for patients with this disease. Methods Between 2008 and 2017, 25 patients with soft tissue sarcoma were treated with pirarubicin (30 mg/m2, 2 days), ifosfamide (2 g/m2, 5 days), and etoposide (100 mg/m2, 3 days) every 3 weeks. The primary endpoint was overall response, and the secondary endpoint was adverse events of this regimen. Results Responses to this regimen according to RECIST criteria were partial response (n = 9, 36%), stable disease (n = 9, 36%) and progressive disease (n = 7, 28%). During the treatment phase, frequent grade 3 or worse adverse events were hematological toxicities including white blood cell decreases (96%), febrile neutropenia (68%), anemia (68%), and platelet count decreases (48%). No long-term adverse events were reported during the study period. Conclusion This regimen was comparable to previously published doxorubicin-based combination chemotherapy in terms of response rate. Although there were no long-lasting adverse events, based on our results, severe hematological toxicity should be considered.

Abstract The decision to treat indolent B-cell NHL is often based on progression of the disease. Most regimens have utilized fludarabine as the purine analog but the myelosuppression and immunosuppression of fludarabine combinations frequently results in severe infections. Combination therapy with pentostatin (P), a purine analog, cyclophosphamide (C), a DNA alkylator, and rituximab (R), an anti-CD20 monoclonal antibody, based on the single-agent activities, documented synergy, and non-overlapping toxicity profiles, may represent a promising approach in the treatment of these patients. To further investigate the efficacy of the PCR regimen for the treatment of indolent NHL, we conducted a phase II study. Patients diagnosed of bulky stage II, stage III/IV low-grade NHL (REAL classification), previously untreated or treated, were eligible. All patients were treated with intravenous infusions of P (4 mg/m2), C (600 mg/m2), and R (375 mg/m2) on day 1 of a 21-day cycle for at least 8 cycles. 2 additional cycles were given for patients with PR or SD after cycle 8 or patients with CR/CRu first evident at cycle 8. Clinical evaluation was performed after cycles 2, 4, 6, 8, and 10 if necessary. Dose modification for hematologic toxicity may be increased to the previous higher level when a hematologic toxicity returned to normal. Two 25% dose reductions or one 50% dose reduction were allowed for nonhematologic toxicity. One hundred patients with indolent NHL, 68 previously untreated, 26 previously treated, and 6 with unknown treatment history, were enrolled in the study. The median age was 61 years (range 29–84) and 63.4% were ECOG PS 0, 36.6% PS1. A total of 550 cycles were given, with a median of 6 cycles per patient. 8 patients were not evaluated for response due to withdrawal of consent (n=1), unacceptable toxicities (n=3), and missing data (n=4). 92 patients received at least two cycles of treatment and were evaluated for response. The highest response rate (RR) achieved was 68%, with 10 (10%) CR, 12 (12%) CRu, 46 (46%) PR, 23 (23%) SD, and 1 (1%) disease progression. Stratified according to previous treatment status, patients with previously untreated NHL had an RR of 47% (CR, CRu 17%) while that of the previously treated was 17% (CR 7%). 14 (14.0%) patients discontinued treatment due to toxicities. Grade 3/ 4 hematological adverse events documented included 10 grade 4 and 16 grade 3 neutropenia. Infectious complications were noted in 8 patients including 3 grade 3 febrile neutropenia, 2 grade 4 febrile neutropenia, and 3 grade 3 infections. A total of 4 deaths were recorded, including 1 due to acute myocardial infarction, 1 suspected cardiac event and 2 unknown causes. This immunochemotherapeutic regimen is active in patients with indolent NHL. The study is currently on-going and updated results will be presented.

Abstract Background: HDT-ASCT with TBC conditioning has emerged as a common consolidation strategy for patients (pts) with relapsed/refractory (rel/ref) primary (PCNSL) or secondary (SCNSL) (Welch et al, Leuk & Lymph 2014). In a prospective study, chemosensitive PCNSL pts in first remission after induction with R-MPV (rituximab, MTX, procarbazine and vincristine) proceeding to HDT-ASCT with TBC conditioning, experienced an encouraging 2-year PFS and OS of 75% and 81%, respectively (Omuro et al, Blood, 2015). Three of these patients experienced transplant-related mortality (TRM, 11.5%), which appears greater than HDT-ASCT for other lymphomas. The purpose of this report is to correlate characteristic toxicities of TBC conditioning for CNSL to pre-HDT-ASCT clinical variables. Methods: The MSKCC IRB approved this retrospective chart review. Eligible pts (n=34) were ≥ 18 years of age with PCNSL or SCNSL that was chemosensitive to induction therapy after which they proceeded to HDT-ASCT conditioned with TBC between December 2006 and April 2015. All pts included were treated outside of prospective clinical trials. Clinically significant grade 3-5 non-hematologic toxicities per CTCAE 4.0 occurring in >20% of pts were recorded from the initiation of conditioning until 6 months post ASCT (Figure 1). Pre-HDT-ASCT variables for analysis include: age, gender, disease (PCNSL or SCNSL), Karnofsky performance status (KPS), hematopoietic cell transplant comorbidity index (HCT-CI), number of prior regimens, prior use of whole-brain radiotherapy (WBRT), and disease status prior to HDT-ASCT (CR/CRu or PR). We evaluated the association of these pre-HDT-ASCT characteristics with the number of clinically significant grade 3-5 non-hematologic toxicities (≥4 vs. <4) using FisherÕs exact test. We further estimated progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier methods. Results: Thirty-three patients (97%) experienced ≥ 1 grade 3-5 non-hematologic toxicity. Febrile neutropenia (grade 3) occurred in 32 pts (94%). Of all pre-HDT-ASCT variables, only the number of prior regimens (>2) was significantly associated with incurring more grade 3-5 non-hematologic toxicities, p=0.04 (Table 1). With a median follow-up for survivors of 12 months (range, 1.5-86.2 months), PFS was 79% (95% CI, 65-96) and OS was 82% (95% CI, 68-98) at 1 year (Figures 2 and 3). During the follow-up period, there were 7 pt deaths: 4 died of disease, 2 died secondary to TRM (5.9%), and one died of a secondary malignancy (squamous cell carcinoma) 86.2 months after HDT-ASCT. There were no progression events beyond 12 months. In a limited subset analysis wherein n=22 had first dose bu pharmacokinetics evaluated, pre-HDT-ASCT variables were not associated with higher bu AUC levels, though 64% of these pts required a dose reduction. Conclusions: We reaffirmed that HDT-ASCT with TBC conditioning is effective consolidation for CNSL, but it is associated with more grade 3-5 non-hematologic toxicity in pts having had >2 prior regimens. Risk-adapted dose attenuation of TBC conditioning for this group of pts may mitigate observed toxicity. Table 1.

679 Background: 5-fluorouracil (5-FU), a synthetic fluoropyrimidine, is a critical component of chemotherapy in many cancers. Its metabolites inhibit Thymidylate Synthetase (TS) causing cessation of DNA synthesis and are misincorporated into DNA and RNA causing ineffective DNA repair and faulty mRNA splicing. The rate limiting step in the catabolism of 5-FU is by the Dihydropyrimidine Dehydrogenase enzyme (DPD) which catabolizes over 80% of 5-FU. Patients with near total DPD enzymatic deficiency develop life threatening toxicity after a single administration and those with less severe deficiency will have delayed elimination of 5-FU and slowly accumulate active metabolites leading to toxicities. Methods: We conducted a pilot retrospective cohort study of African American (AA) and Caucasian patients treated for colorectal cancer over a 9 year period, 2000 – 2008, in this IRB approved study. The primary outcome of interest was the rate of development of grade 3 or 4 neutropenia (Absolute Neutrophil Count <1000/uL = grade 3 and <500/uL = grade 4). Descriptive and univariate analysis were done. To test for differences between AA and Caucasians, we computed independent t-test for continuous and Fisher’s exact test for categorical variables. Relative Risk (RR) and p-values were computed. All statistics were done with SPSS v19 software. Results: There were 66 evaluable patients (40 men, 26 women), 40 AA, 24 Caucasians and 2 of other races. Thirty-eight patients (15 Caucasians and 23 AA) received 5-FU containing chemotherapy. The two groups were comparable in baseline characteristics. AA were more likely to develop grade 3-4 hematological toxicity. Nine of 23 AA (39.1%) and one of 15 Caucasians (6.7%) developed grade 3-4 hematological toxicity. RR 8.56, 95% confidence interval 0.95 – 421.06 (p-value of 0.0561) Conclusions: These results suggest that AA were more likely than Caucasians to have severe hematologic toxicity with the use of 5-FU containing chemotherapy. This difference did not meet statistical significance due to small sample size and few numbers of events in the Caucasian arm. A larger prospective study is needed to further evaluate the observed difference.

556 Background: Liver dysfunction is one of the irritating adverse effects in chemotherapy for colorectal cancer. Polymorphisms of UGTIA1, which is related to metabolism of CPT-11 in the liver, cause severe adverse events. In addition, long-term induction of CPT-11 may involve steatohepatitis. Thus, it is critical to surrogate liver dysfunction in chemotherapy including CPT-11. In this current study, we evaluated whether NAHLD fibrosis score (NFS) which is liver fibrosis marker of nonalcoholic steatohepatitis, is feasible for predicting the effects and adverse events of chemotherapy including CPT-11 for colorectal cancer. Methods: From January 2007 to May 2013, of 118 patients who were diagnosed with unresectable advanced/recurrent colorectal cancer in our hospital, we retrospectively analyzed 89 patients who underwent first line chemotherapy including CPT-11. We statistically analyzed the value of the pretreatment NFS on response rate (RR), progression-free survival (PFS), and hematologic or non-hematologic toxicity of chemotherapy including CPT-11. Results: The median NFS was -1.302 (range=-5.158 to 2.62). Multivariate analysis revealed that NFS was an independent negative predictive marker for RR (coef -0.373 (-0.712 to -0.035), p = 0.031), although no contribution of NFS was observed to PFS (coef 0.958(0.786|1.168), p=0.672). In terms of the adverse events, high value of NFS is an independent risk factor in hematological toxicity (coef 0.93 (0.20 to 1.65), p = 0.012), while not in non-hematological toxicity (coef 0.198 (-0.218|0.613), p=0.351). Conclusions: The pretreatment NFS might be a feasible for predicting response and hematological toxicity in first line chemotherapy including CPT-11 against colorectal cancer.

Abstract Background: The standard chemotherapy regimens for soft tissue sarcoma are doxorubicin-based. This retrospective study aimed to assess the efficacy and safety of pirarubicin, ifosfamide, and etoposide combination therapy for patients with this disease.Methods: Between 2008 and 2017, 25 patients with soft tissue sarcoma were treated with pirarubicin (30 mg/m2, 2 days), ifosfamide (2 g/m2, 5 days), and etoposide (100 mg/m2, 3 days) every 3 weeks. The primary endpoint was overall response, and the secondary endpoint was adverse events of this regimen. Results: Responses to this regimen according to RECIST criteria were partial response (n = 9, 36%), stable disease (n = 9, 36%) and progressive disease (n = 7, 28%). During the treatment phase, frequent grade 3 or worse adverse events were hematological toxicities including white blood cell decreases (96%), febrile neutropenia (68%), anemia (68%), and platelet count decreases (48%). No long-term adverse events were reported during the study period.Conclusion: This regimen was comparable to previously published doxorubicin-based combination chemotherapy in terms of response rate. Although there were no long-lasting adverse events, based on our results, severe hematological toxicity should be considered.
