Catheter Related Thrombosis

Background and Objectives: Cancer associated thrombosis (CAT) is a common complication of neoplasms. Multiple myeloma (MM) carries one of the highest risks of CAT, especially in the early phases of treatment. Autologous stem cell transplantation (ASCT) as the standard of care in transplant-eligible patients with MM carries a risk of catheter-related thrombosis (CRT). The aim of this study was identification of the risk factors of CRT in MM patients undergoing ASCT in 2009–2019. Materials and Methods: We retrospectively analyzed patients with MM undergoing ASCT. Each patient had central venous catheter (CVC) insertion before the procedure. The clinical symptoms of CRT (edema, redness, pain in the CVC insertion area) were confirmed with Doppler ultrasound examination. We examined the impacts of four groups of factors on CRT development: (1) patient-related: age, gender, Body Mass Index (BMI), obesity, Charlson comorbidity index, hematopoietic stem cell transplantation comorbidity index, renal insufficiency, and previous thrombotic history; (2) disease-related: monoclonal protein type, stage of the disease according to Salmon–Durie and International Staging System, number of prior therapy lines, and MM response before ASCT; (3) treatment-related: melphalan dose, transplant-related complications, and duration of post-ASCT neutropenia; (4) CVC-related: location, time from placement to removal. Results: Symptomatic CRT was present in 2.5% (7/276) of patients. Univariate analysis showed an increased risk of CRT in patients with a catheter-related infection (OR 2.4, 95% CI; 1.109–5.19, p = 0.026), previous thrombotic episode (OR 2.49, 95% CI; 1.15–5.39, p = 0.021), previous thrombotic episode on initial myeloma treatment (OR 2.75, 95% CI; 1.15–6.53, p = 0.022), and gastrointestinal complications of ASCT such as vomiting and diarrhea (OR 3.87, 95% CI; 1.57–9.53, p = 0.003). In multivariate analysis, noninfectious complications were associated with higher CRT incidence (OR 2.75, 95% CI; 1.10–6.19, p = 0.031). Conclusions: The incidence of symptomatic CRT in ASCT in MM was relatively low. Previous thrombotic events, especially during the induction of myeloma treatment, increased CRT risk during ASCT. Dehydration following gastrointestinal complications may predispose to higher CRT incidence.

Introduction- High dose chemotherapy followed by autologous hematopoietic stem cell transplantation (ASCT) remains the standard treatment for multiple myeloma (MM) for eligible patients. While ASCT in most centers is performed on an inpatient basis, we and others have shown its feasibility in an outpatient setting. Due to improved supportive care, enhanced patient and caregiver education and preference, the majority of MM patients at our center will initiate outpatient ASCT. However, a part of these patients will require hospital admission pre-emptively due to co-morbid conditions or related to therapy-associated toxicity. To elucidate clinical characteristics and markers predicting for hospital admission in an ambulatory setting, we investigated a total of 1446 MM patients receiving ASCT at UAMS from 2015-2019. Methods- Of the 1446 MM patients, 550 initiated their ASCT as inpatients, 280 started as outpatients but required subsequent hospital admission and 616 completed ASCT in an ambulatory setting. The decision to initiate ASCT as in- or outpatient was based on clinical and social factors. In most cases, Pptients received high dose Melphalan conditioning (74%) followed by dose-reduced Melphalan in combination with Cisplatin, Adriamycin, Cyclophosphamide and Etoposide (PACE, 15%) and BEAM conditioning (9.2%). For comparison between the transplant groups, we used analysis of variance (for continuous-like variables) and Pearson's chi-squared test (for categorical variables). Multivariable logistic regression model was used to examine the combined effects of various clinical variables on the probability of hospitalization after receiving an outpatient autologous transplant. Results- 62% (896/1446) of all patients initiated ASCT on an outpatient basis. Of those, 31% (280/896) required hospital admission within 15 days post-transplant. Main reasons for hospital admission were neutropenic fever (45%), intractable nausea/diarrhea/poor oral intake (29%, n=81/280) followed by more uncommon events such as cardiac problems (6%) and MM related pain (4%, n=12/280) and 16% other reasons (45/280). Median day of admission was D+7 after ASCT (range: D+1 to D+15) with a median length of stay of 8 days (range: 2-49 days). Median age of patients who completed outpatient ASCT (60.4 years) was significantly lower (p<0.001) than of those who required admission (62.9 years) or initiated ASCT as inpatients (61.6 years). Patients initiating ASCT as inpatients had significantly lower Karnosfsky score, albumin and DLCO but higher b2-microglobulin and creatinine compared to those who completed ASCT as outpatients and those requiring admission (all p<0.001). There was no significant difference in day of ANC nadir or engraftment, number of previous ASCTs, body mass index or conditioning regimen between these groups. To predict the need for admission in patients who initiated ASCT in an ambulatory setting, we investigated various clinical markers, including performance status, age, creatinine, b2-microglobulin and lung function tests, and showed that in a multivariant model only advanced age (p=0.02) and reduced albumin (p<0.01) were significant prognostic factors for hospital admission. Thirty day mortality was low in all transplant groups, yet patients who completed their ASCT on an ambulatory setting had significant less 30 day mortality (0.1%, n=1/616) compared to those that underwent inpatient ASCT (1.6%, n=9/550) and those that required admission after ASCT initiation in an outpatient setting (1.4%), p=0.03. Conclusion- Outpatient stem cell transplantation can be safely performed in the large majority of patients with good performance status and organ function. Advanced age and reduced albumin levels predict for a significantly higher likelihood of inpatient admission. These factors could help guiding physicians to better identify patients at high risk for admission during outpatient ASCT.

Abstract Abstract 3000 Autologous stem cell transplantation (ASCT) remains the standard upfront therapy of younger patients with multiple myeloma (MM). Identifying a prognostic threshold amount of mobilized CD34+ hematopoietic stem cells (SC) may become an important modifiable parameter in the era of novel stem cell mobilization strategies. While poor mobilization of CD34+ cells has been shown to cause delays in hematopoietic recovery, the data on long-term clinical outcomes of patients with inferior CD34+ SC collection (‘under mobilizers’) are limited. We analyzed prospectively collected data on 239 adult patients with MM who underwent ASCT at our institution from 01/1996 to 12/2009. Fifty-one patients (21.3%) who collected less than 4 × 106/kg CD34+ SC were classified as ‘under mobilizers’ and were compared to the rest of the study population (n=188) who collected ≥ 4 × 106/kg CD34+ SC. Even though under mobilizers were slightly older (median 59 vs. 54 years, p =0.01), had longer time from diagnosis to ASCT (11 vs. 8 months, p =0.05), and required more days of leukapheresis (5 vs. 3 days, p <0.001), they did not differ from the other group according to the number of prior treatment regimens, mobilization method (only 2 patients received plerixafor), performance status, or disease remission status at transplant (all p >0.2). Median time-to-recovery for both neutrophils (11 vs. 10 days, p <0.001) and platelets (13 vs. 12 days, p <0.001) was delayed among under mobilizers. Under mobilizers had worse relapse-free survival (RFS) (hazard ratio [HR]=1.49, 95% CI, 1.03–2.16, p =0.03) and non-relapse mortality (NRM) (HR=3.59, 95% CI, 1.51–8.56, p <0.01) in multivariable Cox proportional hazards analysis. Even though the association between poor CD34+ SC collection and inferior overall survival did not reach statistical significance (HR=1.42, 95% CI, 0.94–2.16, p =0.1), under mobilizers were found to have significantly higher rates of 100-day post-transplant mortality (p =0.02). We conclude that in the context of ASCT for MM, failure to collect ≥ 4 × 106/kg CD34+ SC is independently associated with worse RFS and NRM. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction:The management of multiple myeloma has become increasingly complex, given late age of onset, underlying co-morbidities, plethora of drugs, and variable clinical presentation and natural history. Practice patterns likely vary based on practice type, physician experience, and geographic distributions. The Multiple Myeloma Research Foundation's (MMRF) CoMMpass Trial (Relating Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile) is a prospective, longitudinal, observation trial in NDMM with the primary goal of correlating patient data and response with molecular profiles. Here, we evaluate practice patterns in NDMM the CoMMpass Trial based on staging, high-risk features, and demographics. Methods: Clinical data were derived from MMRF's CoMMpass IA8, accessed in late July 2016 on https://research.themmrf.org/rp/explore. Independent categorical variables analyzed include International Staging System (ISS), Revised-ISS (R-ISS), LDH (normal vs. above upper limit of normal), Fluorescence-In-Situ Hybridization (FISH) (standard vs. high risk (t(4;14), t(14;16), t(14:20), del17p)), race, performance status (PS) (0-1, 2, 3-4), age (>65, 65-75, 76-80, >80 years), and gender. Dependent variables include use of doublets vs. triplets, the use of triplets using combined immunomodulatory/proteosome inhibition (IMID/PI), receiving or not receiving an autologous stem cell transplantation (ASCT), and timing of transplant (<10 vs. >10 months). For high-risk MM, defined as ISS 3, R-ISS 3, elevated LDH, or high risk FISH, patients receiving doublet therapy without an autologous stem cell transplantation were further analyzed for performance status and age. Descriptive statistics were used. Chi-square testing was used to compare variables, using STATA v14.1. Results: Data on 921 patients has been released and was reviewed. Although men and women had similar upfront therapy, including the use of triplet (57% vs. 61%, p=0.483) and IMID/PI combinations (56% vs. 62%, p=0.181), women were more likely to have an ASCT (44% vs. 34%, p=0.002). When compared to European Americans (EA), African-Americans (AA) were less likely to receive triplets (47% vs. 61%, p=0.004), IMID/PI combination (55% vs. 59%, p=0.001), and ASCT (30% vs. 40%, p=0.034). Patients with high-risk disease were not more likely to be treated more aggressively. Patients with ISS Stage 3 disease were less likely to receive triplets (50% vs. 64%, p=0.002), IMID/PI combinations (51% vs. 66%, p=0.001), or an ASCT (26% vs. 48%, p=<10-3). When comparing standard-risk MM, as defined by LDH or FISH, high-risk patients were not more likely to receive triplet therapy or ASCT. Performance status did not correlate triplet use, but lower rates of IMID/PI combinations and ASCT were noted in those with worse PS. We subsequently reviewed patients with high-risk features who were treated with doublet therapy and without ASCT, specifically looking performance status and age. Of those with elevated LDH, 12 (46%) were younger than 65 years and 12 (46%) had PS<1. Of those with high risk FISH, 20 (49%) were younger than 65 years and 37 (76%) had PS<1. Of those with ISS 3, 24 (26%) were younger than 65 years and 49 (56%) had PS<1. Of those with R-ISS 3, 12 (44%) were younger than 65 years and 17 (63%) had PS<1. Conclusions: The MMRF CoMMpass trial allowed assessment of practice patterns in the United States both inside and outside of academic medical centers. AA appear to be treated less aggressively, possibly explaining shorter survival despite more favorable cytogenetics. Second, high-risk disease does not appear to be treated more aggressively, even in younger patients with excellent performance status. This presented data must be interpreted with caution since this trial does not capture the treating physician's decision-making, nor survival data.
