Objective: Utilization of fertility preservation treatments has increased since the American Society for Reproductive Medicine lifted the "experimental" label for oocyte cryopreservation in 2012. This study characterizes changes in insurance coverage, clinical outcomes, and live birth probabilities over a span of a decade (2012-2022) in patients who underwent planned oocyte cryopreservation. Methods: Retrospective analysis of planned oocyte cryopreservation cycles using vitrification from 2012 to 2022. Medically indicated cycles were excluded. Age, anti-mullerian hormone (AMH), number of mature oocytes vitrified, and insurance coverage were evaluated by year of procedure. Comparative statistics were performed using Kruskal-Wallis and chi-square analysis. Linear regression models and Cochran-Armitage trend test were performed to determine the relationships between each variable and time. Result(s): A total of 4,544 planned oocyte cryopreservation cycles were included. Mean age at egg retrieval decreased significantly over time (37.9 ± 2.9 years versus 34.9 ± 3.3, p < 0.0001). Mature oocytes frozen per cycle rose significantly over time (10.7 ± 7.4 in 2012 versus 13.3 ± 8.6 in 2022, p ≤ 0.0001). Cycles with insurance coverage significantly increased, 0% covered in 2012 versus 46.9% covered in 2022 ( p ≤ 0.0001). Conclusions: Since 2012, patient age at time of egg freezing has decreased, coinciding with a mean increase in AMH and number of mature oocytes frozen per cycle. Younger participation in extending fertility is likely driven by a boost in social awareness regarding reproductive aging, cryopreservation technologies, and improved access to treatment. Modern oocyte cryopreservation includes more access to insurance coverage, shown by nearly half of current cycles benefiting from plan support. Shifts in patient demographics and insurance coverage, paired with updates to stimulation protocols that optimize oocyte yield, are expected to improve the overall prognosis and future fertility of patients who utilize thawed oocytes.

Objective: To assess whether the change in embryo morphology from precryopreservation to postthaw is associated with the embryo transfer success rates in single euploid embryo transfer cycles., Design: Retrospective cohort study., Setting: Academic affiliated fertility clinic., Patient(s): Patients who underwent a single euploid embryo transfer cycle from September 2016 to April 2022 were included. A decision support tool was used to assign each embryo a reproductive potential score on the basis of the day of biopsy, expansion, and grade of trophectoderm and inner cell mass at the time of cryopreservation and after thaw. Embryos were divided into 4 groups: group 1 included embryos with the same score after thaw (reference); group 2 included those with a higher score; group 3 included those with a lower score; and group 4 included those that did not re-expand after thaw., Intervention(s): No interventions administered., Main Outcome Measure(s): The primary outcome was the live birth rates (LBRs) per embryo transfer. The secondary outcomes included the chemical pregnancy, clinical pregnancy, and clinical pregnancy loss rates. Comparative statistics and univariate analyses were performed using the Kruskal-Wallis and χ 2 tests. Multivariate logistic regression fitted with generalized estimating equation was performed to compare the odds of live birth between groups., Result(s): A total of 7,750 embryo transfers performed for 4,613 patients met inclusion criteria: 5,331 in group 1; 486 in group 2; 1,726 in group 3; and 207 in group 4. In the univariate analysis, there was a statistically significant difference in the LBR between groups 1, 2, 3, and 4 (55.8% vs. 51.4%, 47.5%, and 26.6%). Logistic regression controlling for oocyte age, antimüllerian hormone, body mass index, endometrial thickness, year of embryo transfer, time from thaw to final grading, and embryo score before cryopreservation showed significantly lower odds of live birth when the embryo was downgraded (odds ratio [OR], 0.70; confidence interval [CI], 0.62-0.79) or did not re-expand (OR, 0.36; CI, 0.26-0.51) than those with no change in score. When controlling for all variables, there was a significant increase in the odds of live birth between embryos that had a higher score after thaw and those without a change (OR, 1.42; CI, 1.14-1.76). There was no significant difference in the clinical pregnancy loss rate among the 4 groups., Conclusion(s): The change in the quality of the embryo after thaw is an important factor in embryo transfer success. In an adjusted analysis, the chemical and clinical pregnancy rates and LBR per embryo transfer all significantly decrease in embryos that were downgraded or did not expand on the day of single euploid embryo transfer. Embryos that re-expand and have improved quality after thaw have the highest odds of live birth., Competing Interests: Declaration of Interests K.B. has nothing to disclose.

Study Objective: To study pregnancy outcomes after single euploid embryo transfer (SEET) in patients who underwent prior uterine septum resection to those with uteri of normal contour, without Müllerian anomalies or uterine abnormalities including polyps or fibroids, and without a history of prior uterine surgeries., Design: Retrospective cohort study., Setting: Single academic affiliated center., Patients: 60 cycles of patients with prior hysteroscopic uterine septum resection who underwent an autologous SEET between 2012 and 2020 were used as the investigational cohort. A 3:1 ratio propensity score matched control cohort of 180 single euploid embryo transfer cycles from patients without a history of uterine septa were used as the control group., Interventions: No interventions administered., Measurements and Main Results: Pregnancy, clinical pregnancy loss, ongoing clinical pregnancy, and live birth rates in patients with a history of uterine septum resection compared with matched patients without Müllerian anomalies or uterine surgeries. Patients with a prior uterine septum had significantly lower rates of chemical pregnancy (58.33% vs 77.2%, p = .004), implantation (41.67% vs 65.6%, p = .001), and live birth (33.33% vs 57.8%, p = .001) per transfer. No statistical difference in clinical pregnancy loss rates was found when comparing septum patients with controls (8.33% vs 7.8%, p = .89)., Conclusion: Patients with a history of hysteroscopic resection who undergo in vitro fertilization are more susceptible to suboptimal clinical outcomes compared with patients with normal uteri. Early pregnancy loss rates in patients with a uterine septum are higher than in those without; however, after resection, the rates are comparable. Patients born with septate uteri require assessment of surgical intervention prior to SEET, and to optimize their reproductive outcomes., (Copyright © 2024 AAGL. Published by Elsevier Inc.

The frequency and causes of early mortality in patients with newly diagnosed multiple myeloma (NDMM) have not been well described in the era of novel agents. We investigated early mortality in a prospective cohort study of all patients with NDMM registered on the Australian and New Zealand Myeloma and Related Diseases Registry (MRDR) at 36 institutions between July 2011 and March 2020. Early mortality was defined as death from any cause within the first 12 months after diagnosis. A total of 2377 patients with NDMM were included in the analysis, with a median (interquartile range) age of 67.4 (58.9-74.60 years, and 60% were male. Overall, 216 (9.1%) patients died within 12 months, with 119 (4.5%) having died within 6 months. Variables that were independent predictors of early mortality after adjustment in multivariable regression included age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.05-1.08; p < 0.001), Eastern Cooperative Oncology Group performance status (OR 1.50, 95% CI 1.26-1.79; p < 0.001), serum albumin (OR 0.95, 95% CI 0.93-0.98; p < 0.001), cardiac disease (OR 1.96, 95% CI 1.35-2.86; p < 0.001) and International Staging System (OR 1.40, 95% CI 1.07-1.82; p = 0.01). For those with a primary cause of death available, it was reported as disease-related in 151 (78%), infection 13 (7%), other 29 (15%). Infection was listed as a contributing factor for death in 38% of patients., (© 2022 The Authors.

The role of upfront non-myeloablative allogeneic stem cell transplantation (NMA alloSCT) in high-risk multiple myeloma (HR-MM) is unclear. We evaluated outcomes of NMA alloSCT following autologous stem cell transplant (ASCT) compared with ASCT alone for newly diagnosed HR-MM. Two-year progression-free survival was improved in the ASCT-NMA alloSCT group (44% vs 16%; P = 0.035), with a trend for improved overall survival (P = 0.118). These results suggest that ASCT-NMA alloSCT can be considered as upfront therapy in HR-MM., (© 2022 The Authors.

Measurable residual disease (MRD) is being recognised as an optimal method for assessing depth of response, identifying higher risk of relapse, and guiding response-based treatment paradigms for multiple myeloma (MM). Although MRD negativity is increasingly replacing complete response as the surrogate endpoint in clinical trials, its role in real-world practice is less established. We retrospectively analyzed EuroFlow MRD results from patients with newly diagnosed MM (NDMM) who underwent bortezomib, cyclophosphamide and dexamethasone (VCD) induction and high dose melphalan conditioned autologous stem cell transplant (ASCT) at the Alfred Hospital between January 2016 and December 2020. Next generation flow MRD evaluation was performed 3 months following ASCT using the standardised EuroFlow platform. 112 patients with available MRD data were identified to have received VCD induction followed by ASCT. Post ASCT MRD was undetectable in 28.6% of patients. Those who achieved MRD negativity had significantly longer progression free survival (PFS) than those with persisting MRD (24-month PFS of 85% [95% CI: 72.4-99.9%] vs 63% [95% CI: 52.9-75.3%], p = 0.022). Maintenance therapy was associated with improved PFS regardless of MRD status (24-month PFS of 100% [95% CI: NA, p = 0.02] vs 73% [95% CI: 53.1-99.6%] in MRD negative, and 75% [95% CI: 64.2-88.6%] vs 36% [95% CI: 20.9-63.2%, p = 0.00015] in MRD positive patients). Results from this retrospective study of real-world practice demonstrate that Euroflow MRD analysis following standard VCD induction and ASCT in NDMM is feasible and allows more accurate prognostication, providing a platform for response adaptive therapies., Competing Interests: AK has received honoraria from Amgen, Celgene, Pfizer, Roche, CSL, and Sandoz.

Supported by clinical trial proven survival benefit, clinical guidelines recommend upfront autologous stem cell transplantation (ASCT) for eligible MM patients. However, reported real-world utilisation is lower than expected (40-60%). We reviewed ASCT utilisation, demographics and outcomes for MM patients (≤70 years, ≥12-month follow-up) enroled onto the Australian/New Zealand MRDR from June 2012 to May 2020. In 982 patients (<65 years: 684, 65-70 years: 298), ASCT utilisation was 76% overall (<65 years: 83%, 65-70 years: 61%, front-line therapy: 67%). Non-ASCT recipients were older (median age: 65 years vs 60 years, p < 0.001), had more comorbidities (cardiac disease: 16.9% vs 5.4%, p < 0.001; diabetes: 19.1% vs 7.0%, p < 0.001; renal dysfunction: median eGFR(ml/min): 68 vs 80, p < 0.001), inferior performance status (ECOG ≥ 2: 26% vs 13%, p < 0.001) and higher-risk MM (ISS-3: 37% vs 26%, p = 0.009, R-ISS-3 18.6% vs 11.8%, p = 0.051) than ASCT recipients. ASCT survival benefit (median progression-free survival (PFS): 45.3 months vs 35.2 months, p < 0.001; overall survival (OS): NR vs 64.0 months, p < 0.001) was maintained irrespective of age (<65 years: median PFS: 45.3 months vs 37.7 months, p = 0.04, OS: NR vs 68.2 months, p = 0.002; 65-70 years: median PFS: 46.7 months vs 29.2 months, p < 0.001, OS: 76.9 months vs 55.6 months, p = 0.005). This large, real-world cohort reaffirms ASCT survival benefit, including in 'older' patients necessitating well-designed studies evaluating ASCT in 'older' MM to inform evidence-based patient selection., (© 2021.

Objective: To study the impact of the endometrial receptivity analysis (ERA) on live birth rates in frozen embryo transfer (FET) cycles., Design: Retrospective cohort study., Setting: A single, large, university-affiliated infertility practice., Patient(s): Autologous FET cycles between January 1, 2014, and June 30, 2019, were reviewed. Multiple covariates that impact outcomes were used for propensity score matching; 133 ERA patients were matched to 353 non-ERA patients. Patients were assigned to the ERA group if they had an ERA during treatment and underwent at least one "personalized" FET based on the ERA recommendations., Intervention(s): No interventions administered., Main Outcome Measure(s): Live birth rates per cycle in the FET cycle after ERA compared with that of matched non-ERA patients., Result(s): The live birth rates for the ERA group, 49.62%, and the matched non-ERA group, 54.96%, (odds ratio 0.8074; 95% confidence interval, 0.5424-1.2018) were not significantly different, nor was a difference seen in subanalyses based on prior number of FETs or receptivity status., Conclusion(s): The ERA identifies a patient's putative window of implantation with the goal of improving synchrony with the embryo, thereby achieving higher live birth rates. This study used propensity score matching to control for multiple covariates in a heterogenous group of patients to compare live birth rates. There was no difference in the live birth rate in patients who underwent the ERA compared with that of those who did not., (Copyright © 2021 American Society for Reproductive Medicine.

We evaluated the efficacy and tolerability of continuous ixazomib-thalidomide-dexamethasone (ITd: 4 mg, day 1, 8, 15; 100 mg daily; and 40 mg weekly). A total of 39 patients with relapsed/refractory multiple myeloma (RRMM) aged ≥18 years with one to three prior lines of therapy were enrolled from two tertiary centres in Victoria and South Australia, Australia. The overall response rate (ORR) was 56·4% with a clinical benefit rate of 71·8%. The median progression-free survival was 13·8 months [95% confidence interval (CI) 8·2-22·2] and median overall survival was not reached. The median time to best response and duration of response was 3·7 months (95% CI 2·8-10·5) and 18·4 months (95% CI 10·2-31·0) respectively. Prior immunomodulatory drug (IMID) exposure was associated with a lower ORR (40% vs. 73·7%, P = 0·03). Survival outcomes in patients with prior proteasome inhibitor (PI) and/or IMID exposure were similar. Patients received a median (range) of 11 (1-31) cycles of therapy and six patients (15%) remained on therapy at the time of final analysis. Grade 3/4 haematological and non-haematological adverse events were reported in 7·7% and 20·6% of patients respectively. ITd dose reductions were required in 15·4%, 48·7% and 35·9% of patients respectively. The present study demonstrates promising effectiveness and tolerability of ITd as an affordable all-oral PI-IMID approach for RRMM., (© 2021 British Society for Haematology and John Wiley & Sons Ltd.)

Background: Real-world multiple myeloma (MM) data are scarce, with most data originating from clinical trials. The Myeloma and Related Diseases Registry (MRDR) is a prospective clinical-quality registry of newly diagnosed cases of plasma cell disorders established in 2012 and operating at 44 sites in Australia and New Zealand as of April 2020., Methods: We reviewed all patients enrolled onto the MRDR between June 2012 and April 2020. Baseline characteristics, treatment, and outcome data were reviewed for MM patients with comparisons made by chi-square tests (categorical variables) and rank sum tests (continuous variables). Kaplan-Meier analysis was used to estimate progression-free survival and overall survival (OS)., Results: As of April 2020, a total of 2405 MM patients were enrolled (median age, 67 years, with 40% aged > 70 years). High-risk features were present in 13% to 31% of patients: fluorescence in-situ hybridization (FISH) ≥ 1 of t(4;14), t(14;16), or del(17p) 18%, International Staging System (ISS)-3 31%, and Revised ISS (R-ISS)-3 13%. Cytogenetic/FISH analyses were performed in 50% and 68% of patients, respectively, with an abnormal karyotype result in 34%. Bortezomib-containing therapy was the most common first-line therapy (79.3%, n = 1706). Patients not receiving bortezomib were older (median age, 76 vs 65 years, P < .001) with inferior performance status (Eastern Cooperative Oncology Group performance status ≥ 2, 41% vs 18%, P < .001). Median progression-free survival and OS were 30.8 and 65.8 months, respectively. Younger patients had superior OS (76.3 vs 46.7 months, P < .001, < 70 and ≥ 70 years, respectively). R-ISS score was available in 50.7% (n = 1220) of patients, and higher R-ISS was associated with inferior OS (R-ISS-1 vs R-ISS-2 vs R-ISS-3: not reached vs 68.1 months vs 33.2 months, respectively, P < .001)., Conclusion: Clinical registries provide a more complete picture of MM diagnosis and treatment, and highlight the challenges of adhering to best practices in a real-world context., (Copyright © 2021 Elsevier Inc.

Microarray was utilized to determine if a genetic signature associated with resistance to carfilzomib (CFZ) could be identified. Twelve human myeloma (MM) cell lines (HMCLs) were treated with CFZ and a cell-viability profile was assessed categorizing HMCLs as sensitive or resistant to CFZ. The gene expression profiles (GEP) of untreated resistant versus sensitive HMCLs revealed 29 differentially expressed genes. TOP2A, an enzyme involved in cell cycle and proliferation, was overexpressed in carfilzomib-resistant HMCLs. TOP2A protein expression levels, evaluated utilizing trephine biopsy specimens acquired prior to treatment with proteasome inhibitors, were higher in patients failing to achieve a response when compared to responding patients. Logistic-regression analysis confirmed that TOP2A protein expression was a highly significant predictor of response to PIs (AUC 0.738). Further, the combination of CFZ with TOP2A inhibitors, demonstrated synergistic cytotoxic effects in vitro , providing a rationale for combining topoisomerase inhibitors with CFZ to overcome resistance in MM.

In preclinical studies, oral azacitidine (CC-486), a hypomethylating agent, has been shown to have a direct anti-MM effect and in vitro anti-MM synergism when combined with lenalidomide (LEN). We present a phase 1b, single center, 3 × 3 dose escalation study with planned expansion at maximum tolerated dose (MTD), which assessed the safety and efficacy of combining CC-486 with LEN (25 mg d1-21/28) and dexamethasone (DEX) (40 mg weekly) in patients with relapsed/refractory MM who had previously failed LEN. Twenty-four patients were enrolled. The MTD of CC-486 was 150 mg d1-21; recommended expansion dose was 100 mg d1-21. Adverse events were predictable and manageable. ORR was 37.5%; clinical benefit rate was 50%. Median OS was 10.3 m; median PFS was 2.6 m. Correlative proteomics demonstrated that higher MM tumor cell cereblon expression (pretreatment, C1D5) was associated with superior PFS/OS. CC-486, LEN and DEX produced meaningful clinical responses in heavily treated LEN refractory MM patients. Proteomics may have utility in predicting clinical outcomes.

Background: Renal impairment (RI) is a common complication of multiple myeloma (MM) and remains a poor prognostic factor despite improved survival with newer therapies., Patients and Methods: We evaluated baseline characteristics, treatment, and outcomes of newly diagnosed MM patients with RI at diagnosis in the Australia and New Zealand Myeloma and Related Diseases Registry over 5 years to April 2018; we compared patients with RI (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m 2 ) with those with eGFR ≥60. In autologous stem cell transplantation (ASCT) analyses, patients aged 70 years and younger and ≥1 year from diagnosis were included., Results: Overall, 36% of patients with newly diagnosed MM had RI; they were older, had more advanced disease and comorbidities, and worse performance status. Bortezomib-based induction therapy was most commonly used, although administered to fewer RI patients, despite similar response rates. Patients with RI were less likely to receive ASCT; however, recipients had longer progression-free survival (PFS) and overall survival (OS). Patients with RI had shorter OS and PFS after adjusting for age. In ASCT recipients with RI versus no RI, there was no difference in PFS and OS., Conclusion: Our findings in "real world" MM patients with RI confirm that patient-, disease-, and treatment-related factors (such as suboptimal bortezomib and ASCT use), and delays in commencing therapy, might contribute to poorer outcomes, and support the use of ASCT in patients with RI., (Copyright © 2019 Elsevier Inc.

Monitoring tumour burden and therapeutic response through analyses of circulating cell-free tumour DNA (ctDNA) and extracellular RNA (exRNA) in multiple myeloma (MM) patients were performed in a Phase Ib trial of 24 relapsed/refractory patients receiving oral azacitidine in combination with lenalidomide and dexamethasone. Mutational characterisation of paired BM and PL samples at study entry identified that patients with a higher number of mutations or a higher mutational fractional abundance in PL had significantly shorter overall survival (OS) (p = 0.005 and p = 0.018, respectively). A decrease in ctDNA levels at day 5 of cycle 1 of treatment (C1D5) correlated with superior progression-free survival (PFS) (p = 0.017). Evaluation of exRNA transcripts of candidate biomarkers indicated that high CRBN levels coupled with low levels of SPARC at baseline were associated with shorter OS (p = 0.000003). IKZF1 fold-change <0.05 at C1D5 was associated with shorter PFS (p = 0.0051) and OS (p = 0.0001). Furthermore, patients with high baseline CRBN coupled with low fold-change at C1D5 were at the highest risk of progression (p = 0.0001). In conclusion, this exploratory analysis has provided the first demonstration in MM of ctDNA for predicting disease outcome and of the utility of exRNA as a biomarker of therapeutic response.

There is limited data describing dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) in relapsed refractory multiple myeloma (RRMM). We reviewed 65 patients with RRMM receiving DCEP between 2005 and 2017 in two Melbourne Hospitals. Patients had received a mean of three prior treatment lines (range, 1-11). The mean number of cycles of DCEP was two (range, 1-4). Overall response rate (ORR) was 55% whilst 19% achieved MR and SD. Median overall survival (OS) was 9.6 months. Those bridged to autologous stem cell transplant (ASCT) had significantly improved OS compared to those who were not (median 32.8 vs. 10.7 months, p=.0004). Significant treatment-related mortality (TRM) was observed (9.7%), mostly attributable to grade 3-4 neutropenia and febrile neutropenia. Mandatory use of G-CSF is, therefore, warranted to prevent septic complications. In heavily pretreated RRMM, DCEP is an effective bridge to definitive therapy but in the absence of the latter, its value is questionable.

Bortezomib-based induction is often used in transplant-eligible patients with myeloma. The optimal peripheral blood stem cell (PBSC) mobilisation strategy in this context is unclear. We reviewed the efficacy of G-CSF alone (G-alone) vs. G-CSF and cyclophosphamide (G-cyclo: standard dose: 1.5-2 g/m 2 ; high dose: 3-4 g/m 2 ) PBSC mobilisation strategies in 288 patients who only received bortezomib, cyclophosphamide and dexamethasone (VCD) induction prior to autograft across six apheresis centres from November 2012 to June 2017. 'Uncomplicated successful mobilisation' was defined as achieving a PBSC yield of ≥4 × 10 6 /kg within two aphereses, without plerixafor or mobilisation-associated toxicity (predominantly febrile neutropenia, FN). Success rates were 84% in G-cyclo standard dose (6% FN), 64% in G-cyclo high dose (18% FN) and 69% in G-alone (plerixafor successfully salvaged 8/9 patients). Median total stem cell yield was significantly higher with G-cyclo, but not different between the two cyclophosphamide doses. Age greater than the median of 61 years was associated with higher failure rates (22 vs. 11%, p = 0.01) and lower PBSC yield, especially in the G-alone group. Prior radiotherapy exposure did not impact on collection success. Our observations suggest that both G-cyclo standard dose and G-alone are reasonable mobilisation strategies. The former may be preferred if salvage plerixafor is unavailable.

Marizomib (MRZ) is an irreversible, pan-subunit proteasome inhibitor (PI) in clinical development for relapsed/refractory multiple myeloma (RRMM) and glioma. This study analysed MRZ, pomalidomide (POM) and low-dose dexamethasone (Lo-DEX) [PMD] in RRMM to evaluate safety and determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D). Intravenous MRZ (0·3-0·5 mg/m 2 ) was administered over 2 h on days 1, 4, 8, 11; POM (3-4 mg) on days 1-21; and Lo-DEX (5 or 10 mg) on days 1, 2, 4, 5, 8, 9, 11, 12, 15, 16, 22 and 23 of every 28-day cycle. Thirty-eight patients were enrolled that had received a median of 4 (range 1-10) prior lines of therapy; all patients received prior lenalidomide and bortezomib. No dose-limiting toxicities (DLTs) were observed and 0·5 mg/m 2 MRZ was determined to be the RP2D. The most common treatment-related ≥Grade 3 adverse events were: neutropenia (11/38 patients: 29%), pneumonia (4/38 patients 11%), anaemia (4/38 patients; 11%) and thrombocytopenia (4/38 patients; 11%). The overall response rate and clinical benefit rate was 53% (19/36) and 64% (23/36), respectively. In conclusion, PMD was well tolerated and demonstrated promising activity in heavily pre-treated, high-risk RRMM patients., (© 2017 John Wiley & Sons Ltd.)

Background: Successful engraftment and reconstitution of the innate and adaptive immune system are associated with improved outcomes in recipients of allogeneic hematopoietic stem cell transplantation (HSCT). A clinically meaningful and simple biomarker of immunosuppression could potentially assist clinicians in their decision-making. We aimed to determine the relationship between T-cell production of interferon gamma (IFN-γ) in response to phytohemagglutinin (PHA) to clinical outcomes in HSCT recipients., Methods: A prospective observational multicenter study of 73 adult allogeneic HSCT recipients was conducted in Melbourne, Australia. Eligible participants were >18 years and at risk of cytomegalovirus disease. T-cell responses to PHA were assessed at 3, 6, 9, and 12 months post-HSCT using the commercial quantiferon-cytomegalovirus assay, which quantifies IFN-γ production by ELISA following stimulation with PHA. A low response was defined as IFN-γ <0.5 IU/ml following stimulation with PHA., Results: At 3 months post-HSCT, high responses to PHA (median IFN-γ 7.68 IU/ml) were seen in 63% of participants and low responses to PHA (median IFN-γ 0.06 IU/ml) in 37%. IFN-γ responses to PHA were significantly associated with the severity of acute graft versus host disease (AGVHD) (spearman r  = -0.53, p  < 0.001) and correlated with blood lymphocyte count (spearman r  = 0.52, p  < 0.001). Twelve month overall survival was greater in individuals with high compared to low IFN-γ response to PHA at 3 months [92 vs. 62%, respectively, Cox proportional hazard ratio (HR): 4.12 95% CI: 1.2-13.7, p  = 0.02]. Non-relapse mortality (NRM) was higher in individuals with low IFN-γ response to PHA (competing risk regression HR 11.6 p  = 0.02). In individuals with no AGVHD compared to AGVHD and high IFN-γ response to PHA compared to AGVHD and low IFN-γ response to PHA, 12-month survival was 100 vs. 80 vs. 52%, respectively (log rank test p  < 0.0001)., Conclusion: Low IFN-γ response to PHA at the 3-month time-point following allogeneic HSCT was predictive of reduced 12-month overall survival, increased NRM, and reduced survival in recipients with AGVHD. Assessing IFN-γ response to PHA post-HSCT may be a clinically useful immune biomarker.

Background: A simple test to identify recovery of CMV-specific T-cell immunity following hematopoietic stem cell transplantation (HSCT) could assist clinicians in managing CMV-related complications., Methods: In an observational, multicenter, prospective study of 94 HSCT recipients we evaluated CMV-specific T-cell immunity at baseline, 3, 6, 9, and 12 months after transplant using the Quantiferon-CMV, an enzyme-linked immunosorbent spot assay (ELISpot), and intracellular cytokine staining., Results: At 3 months after HSCT, participants who developed CMV disease (n = 8) compared with CMV reactivation (n = 26) or spontaneous viral control (n = 25) had significantly lower CD8+ T-cell production of interferon-γ (IFN-γ) in response to CMV antigens measured by Quantiferon-CMV (P = .0008). An indeterminate Quantiferon-CMV result had a positive predictive value of 83% and a negative predictive value of 98% for identifying participants at risk of further CMV reactivation. Participants experiencing CMV reactivation compared with patients without CMV reactivation had a reduced proportion of polyfunctional (IFN-γ+/tumor necrosis factor α-positive) CD4+ and CD8+ T cells and a higher proportion of interleukin 2-secreting cells (P = .01 and P = .002, respectively)., Conclusions: Quantifying CMV-specific T-cell immunity after HSCT can identify participants at increased risk of clinically relevant CMV-related outcomes., (© The Author 2017.

Multiple myeloma (MM) is the second most common hematologic malignancy and is predominantly a disease of the elderly. In the past 2 decades, a range of new therapeutic options have become available, leading to improvements in patient outcomes, including both attainment of remission and overall survival. These improved outcomes have heralded a paradigm shift from a palliative approach toward more active management, including the use of sequential therapies, with the goal of prolonging progression-free and overall survival and preserving organ function to enable delivery of further therapy at relapse. Until now, most outcome data for MM have come from clinical trials, with few reports available on patients treated outside the clinical trial setting-in the "real world." Clinical trials are routinely undertaken in specialist centers, and extrapolation of these trial data to broader clinical practice might not accurately reflect "real-world" patient outcomes. Optimal management of MM is of key importance for positive patient outcomes, and further scrutiny of the efficacy and safety of the various reported therapies and how clinical trial findings are being translated or applied in the real-world management of MM is required. In the present review, we have described the minimal published evidence available through a comprehensive published data search of MEDLINE using the OvidSP interface on the management and outcomes of MM outside the setting of clinical trials, including evidence on the uptake of new therapies and their efficacy and tolerability in standard practice. Clinical registries might be able to help provide these data in the future., (Copyright © 2016 Elsevier Inc. All rights reserved.)

This study evaluates prognostic markers as predictors of clonal evolution (CE) and assesses the impact of CE on overall survival (OS) in a population-based cohort of 159 consecutive eligible patients with chronic lymphocytic leukemia (CLL) obtained from the British Columbia Provincial CLL Database. CE was detected by interphase fluorescence in situ hybridization (FISH) in 34/159 patients (21%) with 65% of CE patients acquiring deletion 17p or 11q. CD38 positive status (≥30%) on flow cytometry predicted 2.7 times increased risk of high-risk CE (acquisition of deletion 17p or 11q) on multivariate analysis. Prior CLL therapy was not a significant predictor of CE. CE was associated with 4.1 times greater risk of death when analyzed as a time-dependent variable for OS after adjusting for age, lymphocyte count, and FISH timing. High-risk CE was associated with worse OS while acquisition of low/intermediate-risk abnormalities (trisomy 12, deletion 13q, and IGH translocation) had no difference in OS. Our study demonstrates the negative impact of CE detected by FISH on OS in this population-based cohort. These data provide support for repeating FISH testing during CLL follow-up as patients with high-risk CE have reduced survival and may require closer observation., (Copyright © 2016 Elsevier Inc.

Background: Plasma cell dyscrasias (PCD) are a spectrum of disorders resulting from the clonal expansion of plasma cells, ranging from the pre-malignant condition monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM). MM generates a significant burden of disease on the community and it is predicted that it will increase in both incidence and prevalence owing to an ageing population and longer survival secondary to new therapeutic options. Robust and comprehensive clinical data are currently lacking but are required to define current diagnostic, investigational and management patterns in Australia and New Zealand (ANZ) for comparison to both local and international guidelines for standards of care. A clinical registry can provide this information and subsequently support development of strategies to address any differences, including providing a platform for clinical trials. The Myeloma and Related Diseases Registry (MRDR) was developed to monitor and explore variations in practices, processes and outcomes in ANZ and provide benchmark outcomes nationally and internationally for PCD. This paper describes the MRDR aims, development and implementation and discusses challenges encountered in the process., Methods: The MRDR was established in 2012 as an online database for a multi-centre collaboration across ANZ, collecting prospective data on patients with a diagnosis of MGUS, MM, solitary plasmacytoma or plasma cell leukaemia. Development of the MRDR required multi-disciplinary team participation, IT and biostatistical support as well as financial resources., Results: More than 1250 patients have been enrolled at 23 sites to date. Here we describe how database development, data entry and securing ethics approval have been major challenges for participating sites and the coordinating centre, and our approaches to resolving them. Now established, the MRDR will provide clinically relevant and credible monitoring, therapy and 'real world' outcome data, to support the conduction of high quality studies. In addition, the Myeloma 1000 sub-study is establishing a repository of paired peripheral blood specimens from registry patients to study mechanisms underlying disease progression., Conclusion: Establishment of the MRDR has been challenging, but it is a valuable investment that will provide a platform for coordinated national and international collaboration for clinical research in PCD in ANZ.
