Dose Modifications

18525 Background: Bleomycin used in the ABVD regimen is associated with a risk of pulmonary toxicity (10 - 19%). Pts with early signs of suspected bleomycin toxicity are often treated with modifications of the regimen. We conducted a retrospective study of patients with HD at our institution in whom bleomycin dose was modified or discontinued during their course of therapy with ABVD. Their response to modified therapy and possible predisposing factors were analysed. Methods: IRB approval was obtained for this study. Tumor registry data for adult pts diagnosed with HD between 2004 and 2006 were analysed for age, stage, sex, histology, smoking history, reduction in bleomycin dose and outcomes. Results: 38 pts were diagnosed with HD at our institution during this time period. Histology: NS: n=15(39.4%), MC: n=16(42.1%), NLP: n=2(5.2%), LR: n=2(5.2%). Histology NOS: n=4(10.5%). 8 pts with bleomycin dose modifications were identified. Pt. characteristics : Med.age 46 yrs (28- 64 ), M:F3:5; 7 of 8 were newly diagnosed and one pt had recurrent HDs. Stages: Stg I: n = 1; Stg II: n= 3; Stg III: n = 3, Stage IV: n= 1, B symptoms : n = 3. Histology: MC (n = 6), NS (n = 1). Unk n=1. 4 of 8 pts were ex-smokers. One patient never received bleomycin due to initial poor PFTs. 7 pts had bleomycin discontinued due to symptoms and decrease in DLCO during their treatment. One patient was continued on 50% reduced dose bleomycin for 2 cycles prior to discontinuation of bleomycin. The distribution of the number of patients discontinuing bleomycin by cycle of treatment is as follows: C#2: n=1; C#3: n=2; C#4: n=1; C#5: n=2. The complete response rate was 100% in this group despite bleomycin dose modification. There were no relapses after a median follow up of 18 mos (range: 8- 33). One patient treated for recurrent HD had severe pulmonary toxicity and did not receive any further treatments. All other patients completed their intended cycles of treatment. Conclusions: Despite bleomycin modification in this small series of pts treated initially with ABVD, DFS remains excellent with no noted relapses at this early follow up. Majority of pts requiring dose modifications had MC histology. Further trials are needed to evaluate the role of bleomycin in the ABVD regimen. No significant financial relationships to disclose.

e16521 Background: Small published series suggested that three progressively rising CA-125 values, doubling of CA-125, and an absolute rise of 5 U/mL from the nadir, all while remaining in the normal range were highly associated with disease recurrence. This study aims to validate these proposed criteria in a larger population. Methods: We conducted a retrospective review of the records of patients with stages IIIC and IV epithelial ovarian cancer treated with primary surgery and adjuvant chemotherapy between 1994 and 2006. Only patients who had a complete response to chemotherapy verified by normal CT scan, CA-125 and physical examination were included. Nadir CA-125 level was defined as the first CA-125 measurement after completing chemotherapy. Available CA-125 values from diagnosis to recurrence or to last follow up were collected and evaluated for meeting any of the criteria above. Results: 91 patients with a median age of 59 (42 - 88) met the inclusion criteria. 82 patients had stage IIIC (90%) and 9 patients (10%) had stage IV. 86 patients (94.5%) had papillary serous histology and 88 patients had grade 3 (96.7%) disease. Median follow up was 43.7 months (12.6 - 156). Table 1 shows the number of patients who met any of the above CA-125 criteria in total and divided by the presence or absence of recurrence. There was no statistically significant difference in meeting any of the CA-125 criteria between the recurrence and no recurrence groups. Meeting at least one of the CA-125 criteria had 50% sensitivity, 65% specificity, and 86% positive predictive value for recurrence. The median time to recurrence in patients who met at least one CA-125 criteria was 3.8 months (0.2 - 12.4) and the median follow up time after meeting one of the CA 125 criteria in patients who did not recur was 88.5 months (10.4 - 188) Conclusions: Rising CA-125 levels within the normal range that meet any of the above criteria are highly predictive (86%) of recurrence within 12 months and closer observation is warranted.

e21567 Background: Merkel Cell Carcinoma (MCC) is a cutaneous malignancy with neuroendocrine differentiation, linked to infection with polyomavirus (MCPyV) in 80% of cases. PD1 inhibitors have recently been approved for this indication with ORR, 33-56%; CR, 11-24%; PFS, about 17 months; OS, about 12 months. Nivolumab was tested in the neoadjuvant setting with similar responses with pathological CR, 47%. Methods: Adjuvant pilot study (NCT03798639) with two immunotherapy regimens administered for one year to patients with completely resected MCC at high risk of recurrence (primary lesion of 2 cm or greater, positive or close margins ( < 2 cm), perineural or lymphovascular invasion, mitotic index ≥ 20 mitotic figures per mm2, lymph node involvement (stage pIIIA or pIIIB) with or without extracapsular extension, or completely resected stage IV disease). Arm 1, nivolumab 480 mg q 4 wks and radiation therapy (RT) 50-60 Gy in 25-30 fractions, per standard of care. Arm 2, nivolumab 240 mg q 2 wks and ipilimumab 1 mg/kg q 6 wks. Primary objective was feasibility and completion of treatment in this population. Safety profile (CTCAE v5.0) and recurrence-free survival (RFS) after 18 months were secondary endpoints. Patients were randomly allocated 1:1. Results: Ten patients were screened from January 2019 until April 2020, when COVID put the study on hold and the sponsor discontinued the free drug supply. Seven were enrolled. Four were allocated to Arm 1 and three to Arm 2. Patient characteristics in Table. All patients have completed treatment and are in follow-up. Arm 1: all four patients completed radiation therapy and immunotherapy with no dose modifications or delays. Arm 2: one patient had nivolumab delayed 2 weeks for cellulitis, and another missed the last four last doses of nivolumab for cholecystitis and pancreatitis requiring surgery, unrelated to the immunotherapy. Adverse events (AE) were as expected. Arm1 caused more grade 2 and 3 AEs then Arm2 (no grade 3). One patient each discontinued treatment, in Arm 1 for progression and Arm 2 for immunotoxicity (temporal arteritis grade 2). One recurrence was observed in Arm 1 and none in Arm 2. Conclusions: The number of patients expected to recur at 1 year is 20%. Our observed data is insufficient to establish efficacy. However with no patient recurring in the ipilimumab arm after 18 months of follow-up and lower observed side effects, we would favor this regimen for the next trial.

Abstract Acute corticosteroid-refractory graft-versus-host-disease (GvHD) is a life-threatening complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reported mortality rates of 40-60%. Our previous study (Spoerl S et al. Blood 2014) had shown the induction of tolerogenic regulatory T cells after ruxolitinib treatment in the mouse and clinical responses in six patients with corticosteroid-refractory GvHD. Here we report the outcome of 14 patients with GvHD refractory to steroids and at least two other lines of treatment who received ruxolitinib as a salvage treatment. Ten patients were classified as acute and four as chronic GvHD involving the skin, intestinal tract and liver as detailed in Table 1. Patients were treated with ruxolitinib at a starting dose of 5 mg orally twice daily with a dose increase to 10 mg orally twice daily. Clinical and histopathological grading of skin, intestinal and liver GvHD was performed according to established criteria. Of 14 patients, 13 responded with respect to clinical GvHD symptoms and serum levels of pro-inflammatory cytokines. Three patients with histologically proven acute skin or intestinal GvHD grade I, achieved a complete response. One non-responder discontinued ruxolitinib after one week because of lack of efficacy. In all other patients corticosteroids could be reduced after a median treatment of 1.5 weeks. Serum levels of IL-6 and soluble IL-2R were measured prior and after the start of ruxolitinib and declined in the majority of the analyzed patients (n=11). CMV reactivation was observed in four out of 14 patients and responded well to antiviral therapy. Two out of 14 patients developed cytopenia during ruxolitinib treatment that was mild and did not require dose reduction or transfusion. Our results indicate that treatment of corticosteroid-refractory GvHD with ruxolitinib is safe and well tolerated. Despite the low number of patients treated so far, our results demonstrate that ruxolitinib reduces the severity of corticosteroid-refractory GvHD and support further development of therapeutic JAK1/2 inhibition as a salvage treatment in GvHD.

In patient 01, ruxolitinib was discontinued at week 16 because of complete resolution of all GvHD signs. The patient did not develop any signs of GvHD after discontinuation of ruxolitinib until last follow up. Disclosures Off Label Use: Ruxolitinib in GvHD.

7127 Background: Abraxane (A) is a cremophor free, albumin-bound nanoparticle of paclitaxel (P) approved for the treatment of metastatic breast cancer. Belani et al. (JCO 21: 2933–2939, 2003) reported that P 100 mg/m2 days 1, 8 and 15 q 28 days with C AUC 6 on day 1 led to a 32% response rate in 132 patients (pts) with NSCLC. The median time to progression (TTP) was 35 weeks (wks) for stage IIIB and 29 wks for stage IV. Methods: This study was designed to determine if substituting A for P at an identical dose would lead to an improved response rate, TTP or decreased toxicity. Results: Fifty-six pts with stage IIIB/IV NSCLC previously untreated with chemotherapy were enrolled. The median age was 66 (range 37 - 83); 37 were male and median ECOG performance status was 1 (range 0–2). Thirteen pts were stage IIIB. Metastases included bone (17), liver (7), brain (2) and lymph nodes (16). Currently a total of 239 cycles of therapy have been administered with a median of 4 (range 1–8) cycles per pt. In 194 (81%) full dose A was administered on days 1, 8 and 15. The table below shows toxicities compared to P: Seven pts (13%) experienced grade (G) 1 neuropathy and 3 pts (5%) experienced G 2 neuropathy. Five pts were inevaluable for response due to removal from study after <2 cycles of treatment (2 died from progressive disease, 2 because of toxicity - thrombocytopenia and neutropenia - and 1 refused). Of 51 evaluable pts 1 (2%) had a complete response and 23 patients (45%) achieved a partial response. Four of 10 evaluable stage IIIB pts obtained a PR. Twenty-one pts were stable for at least 12 weeks of whom twenty remain stable at 12–29 weeks and one progressed at 23 weeks. A total of 13 pts have progressed and 3 pts have died. The Kaplan-Meier estimate of median TTP is 23 wks and maximum follow up is 34 wks. Conclusions: We conclude that combining A and C is tolerable and active in the treatment of newly-diagnosed NSCLC and antitumor activity compares favorably to that of P/C. Further studies are warranted in this population. [Table: see text] [Table: see text]

e15146 Background: BM is diagnosed in 70-80% of men with metastatic PCa. Less is known about the timing of BM diagnosis following incident non-metastatic PCa and associated patient characteristics. In this study, we determined the incidence and timing of post-diagnosis BM (BMpd) among PCa patients (pts) by incident stage, age, race and year of diagnosis using a large observational dataset. Methods: We analyzed pts aged 66 or older from the linked Surveillance, Epidemiology, and End Results and Medicare (SEER-Medicare) database. Pts with PCa were identified between 2000 and 2007 and were followed until death, Medicare disenrollment, HMO enrollment, or end of the study (December 31, 2009). The cohort included incident stage III and IV(M0) PCa in SEER, and identified BM occurring either within (i.e., +/-) 1 month of the SEER diagnosis month (BM90) or beyond the initial 90-day window (BMgt90) based on the presence of at least one inpatient or one outpatient claim with a diagnosis code of 198.5. We calculated summary and chi-square statistics to examine BMpd, BM90, and BMgt90 by incident stage, age, race and year of PCa diagnosis. Results: Among 9,188 Stage III (72%) and IV(M0) (28%) PCa pts who met inclusion/exclusion criteria, 14.6% (n=1,345) had BMpd: 2.3% (n= 217) had BM90 and 12.3% (n=1,128) had BMgt90. Average age was 72 years and 9% were African American (AA). Incidence of BMpd varied by stage (stage III: 11%; stage IV/M0: 25%; p<0.001) and by age group (66-74 years: 13%; 75-84 years: 19%; >85 years: 22%; p<0.001) but not by race (White: 15%; AA: 16%; Other: 13%; p=0.49). The diagnosis BM90 and BMgt90 varied with stage (stage III: 2% and 9%; stage IV(M0): 4% and 21%; p<0.0001) and age (66-74 years: 2% and 11%; 75-84 years: 3% and 16%; >85 years: 5% and 17%; p<0.001). The incidence of BM decreased over time whether considering BMpd (19% in 2000 to 9% in 2007; p<0.001), BM90 (4% in 2000 to 2% in 2007; p=0.03) or BMgt90 (16% in 2000 to 6% in 2007; p<0.001). Conclusions: BM occurred in only 2% of incident stage III/IV(M0) PCa pts within 1 month of diagnosis, but nearly 15% were diagnosed with BM during a median follow-up of 57 months. Prevalence of BM was highest in stage IV(M0) and older pts.

8543 Background: We previously reported results from a phase 1/2 trial of CRd in NDMM (NCT01029054), demonstrating a high rate (42%) of stringent complete response (sCR) and overall favorable efficacy /safety after a median of 12 cycles of treatment (tx) and a median follow-up of 13 mo (Jakubowiak et al Blood, 2012). Here we report updated results after extended tx and additional 12 mo of follow-up. Methods: Patients (pts) received 28-day (d) cycles of carfilzomib (CFZ) 20–36 mg/m2 IV (d1, 2, 8, 9, 15, 16), lenalidomide (LEN) 25 mg PO (d1–21), and dexamethasone 40/20 mg PO wkly (cycles 1–4/5–8). For cycles 8–24, CRd was given with a modified CFZ schedule (d1, 2, 15, 16) and then LEN alone after cycle 24. Stem cell transplant was an option after cycle 4. Response was assessed by IMWG plus nCR. Results: As of Nov 2012, 53 pts had received a median of 22 CRd cycles (range 2–24); 7 pts opted for transplant; 24 continued LEN maintenance for median 8 mo (range 1–10). Median follow-up was 25 mo (range 5–37). With extended tx, the CR rate was 64%; sCR improved from 42% to 53%, ≥nCR from 62% to 72%, and ≥VGPR from 81% to 87% (follow-up 13 vs 25 mo); ≥PR remained at 98%. Immunophenotypic CR (IMWG) was achieved in 22/26 evaluated pts. Of pts in sCR, 25% had high-risk cytogenetics per IMWG. In pts who did not proceed to transplant (n=46), the sCR was 59%, CR 70%, ≥nCR 78%, ≥VGPR 91%, and ≥PR 100%. Over the course of tx, depth of response improved. Median time to ≥VGPR was 4 cycles (range 2–17), ≥nCR 4.5 cycles (range 2–15), and sCR 10 cycles (range 4–30); 2 pts converted to sCR during LEN maintenance. At 2 years, the estimated PFS rate was 94% and OS was 98%; for pts with sCR, rates were 96% and 100%, respectively. Adverse event types, rates, and dose modifications during extended tx were comparable with those previously reported. There was 1 death off study due to disease progression. Conclusions: Extended follow-up showed that depth of response continued to improve over the course of prolonged CRd tx, resulting in exceptional CR, sCR, and PFS. Extended tx continued to be well tolerated. The results compare favorably with historical studies in both transplant and non-transplant NDMM. Clinical trial information: NCT01029054.

426 Background: Locoregional management of muscle-infiltrating bladder cancer (MIBC) after neoadjuvant chemotherapy (NAC) is controversial, because of both the morbidity of radical cystectomy (RC). Bladder preservation may be feasible after complete tumor response. Methods: This single-center retrospective study included 120 MIBC patients (stages ypT2-4aN0-3M0) treated between 2011 and 2017 with up to 6 cycles of neoadjuvant dose-dense Methotrexate, Vinblastin, Doxorubicin and Cisplatin (DD-MVAC). The primary outcome was relapse-free survival (RFS) depending on pathological findings on RC specimens, classified as either pathological complete response (pCR: ypT0N0/x), residual organ-confined disease (yOCD: ypTa/is/1/2N0/x), residual non-organ-confined disease (yNOCD: ypT≥3Nany or ypTanyN1-3). Secondary objectives included the rate of pCR in RC patients, the rate of ypT0 in the intention-to-treat population, and RFS in ypT0 patients according to locoregional management. Results: After a median number of 5 cycles of NAC, RC was performed in 75% of the patients, concurrent radiochemotherapy (CRC) in 11% and cystoscopic surveillance (CS) in 8%. In the intention-to-treat population, the ypT0 rate was 47%. Among 90 patients who underwent RC, 49% achieved pCR, 16% had yOCD and 34% yNOCD. Median follow-up in RC patients alive at last follow-up was 40 months. Three-year RFS was 86% in RC patients with pCR, 69% in patients with yOCD and 21% in patients with yNOCD (p < 0.0001). Outcomes were similar between ypT0 patients treated with either RC or CRC/CS (3-year RFS: 81% vs 100%, p = 0.20). Limitations to this study included its restrospective design and the lower number of patients treated with CRC/CS. Conclusions: Patients reaching ypT0 after dose-dense NAC show improved prognosis regardless of locoregional treatment. Patients with yOCD are frequently cured by RC, as opposed to patients with yNOCD. Prospective trials are needed to compare upfront cystectomy and bladder-sparing management in patients with both pCR or yNOCD.

e13017 Background: HER2-directed therapies enable a small number of patients with de novo HER2+ metastatic breast cancer (MBC) to achieve long term durable responses (DR). However, clinic-pathologic factors that correlate with DRs in de novo HER2+ MBC are unknown. Expert opinion dictates indefinite HER2-directed therapies for patients who achieve DRs, but real-world examples of this practice, especially the effect on cardiotoxicity, are lacking in the literature. Methods: This is a retrospective case control study of patients with de novo HER2+ MBC who received treatment with trastuzumab at two NCI designated cancer centers between the years 2012-2017. Patients were included if ≥2 years of follow up data were available or if patients were deceased. DRs are defined as radiographic complete or partial response without progression or death at any point after diagnosis. Controls are patients with evidence of radiographic progression or death any point after diagnosis. Age at diagnosis, ER/PR status, site of metastasis, and initial treatment were analyzed. An un-paired T test for age and fisher exact test for categorical variables were used. Results: A total of 96 patients with de novo HER2+ MBC, 28 with DRs and 68 with progression, were identified. Average follow up length for patients with DR was 90 months (range 27-224 months). Patients who progressed had a mPFS of 17.5 months and a mOS of 60 months. Results are shown in Table. Additionally, six patients (6.3%) developed reduced ejection fraction, one with DR, five with progression. Nine patients have been receiving trastuzumab for over ten years with no evidence of disease. Only one patient opted to discontinue this therapy a year after complete response and is disease free five years from diagnosis. Conclusions: Nearly a third of patients with de novo metastatic HER2+ MBC in our dataset achieved DR. Factors that predict DRs include single organ involved by metastatic disease and more intensive upfront chemotherapy including trastuzumab and pertuzumab. The majority of patients with DR continued HER2 directed therapy indefinitely with minimal cardiotoxicity. In the absence of predictive biomarkers of DRs, indefinite trastuzumab administration is common practice for these patients. [Table: see text]

Previous research has shown that surgery in a Dutch Adrenal Network (DAN) center increases the chance of survival. We aim to explore the determinants and survival of patients with ACC recently treated in the Netherlands both within and outside DAN centers. Methods: We analyzed retrospectively collected data from 172 adult patients with newly diagnosed ACC and 97 patients with recurrence or new metastases, registered between 2014 and 2019 in the Netherlands Cancer Registry. Differences in survival were analyzed with cox-regression analysis. Results: More than half of the new cases presented with advance disease (25.7% stage III, 34.6% stage IV) and the median survival was 29 months. The majority of treatments occurred within a DAN center (87.2% of surgery, compared to 56.4% between 1999 and 2009; and 94.5% of medical treatment). There were no differences in patient characteristics between the centers apart from a relatively high number of patients with stage IV disease outside DAN centers (47.2% vs. 28.7%). Adrenal resection and mitotane therapy both resulted in a significant survival benefit (resection HR 0.29, CI95%[0.17–0.49]; mitotane HR 0.61, CI95%[0.37–0.99], corrected for stage). Still, a remarkable proportion of patients with advanced disease received no mitotane treatment (39.8%). Due to the small number of patients treated outside DAN centers, survival benefits could not be tested. Conclusions: Centralization of ACC care in the Netherlands has improved since the previous report, but a further improvement in centralization of surgery can be made. Adrenal resection and mitotane treatment remain the main form of treatment, with a clear survival benefit. Further research is necessary to determine why mitotane treatment is withheld in a large proportion of patients with advance disease.

e21025 Background: In OD and OA, the 1p and 19q deletion has prognostic value in survival. It is also a predictive factor for response to chemotherapy. Fluorescence in situ hybridization (FISH) is the standard method for its evaluation. CISH could be an alternative that has already been validated in other neoplasias. In OD and OA, this combined deletion is present in about 50% of patients when analyzed with FISH. Methods: Patients resected at Clinica Reina Fabiola from january 2006 to january 2010 and diagnosed of OD and OA were propectivelly included. Paraffin-embebed tumor tissue was analyzed for 1p19q deletions by CISH. The results were correlated to the histology (OD and OA) and grade (II and III) of the tumors. Results: The demographic features of the patients from the present study coincide with literature. The 1p and 19q deletion was found in 3 of the 24 patients analyzed (13%). The combined deletion was only found in those with grade II OD. No combined deletion was found in patients diagnosed of grade III OD and grade II and III OA. In the subgroup of patients with grade II OD, the combined deletion was observed in 3 of 11 patients (27%). The 3 patients in which the deletion in both chromosomes was observed, received treatment with chemotherapy and radiotherapy, all of them with complete response. 5 years DFS was 90%-median follow up 36,8 (CI: 30,5-42,98) Conclusions: The detection of the combined deletion with CISH technique was inferior (13%) than the literature. We cannot demonstrate that CISH is a reliable method for the detection of the 1p and 19q deletion. The possible reasons of this difference could be attributed to the number of patients of the study, to deviations in the procedures of the test or to the fact that the CISH method is not coincident with FISH. This prospectivelly monoinstitutional results are also different to our previous report, and may be due to different pathological evaluation.
