RESUMEN
The most important challenges in acute promyelocytic leukemia (APL) is preventing early death and reducing long-term events, such as second neoplasms (s-NPLs). We performed a retrospective analysis of 2670 unselected APL patients, treated with PETHEMA "chemotherapy based" and "chemotherapy free" protocols. Only de novo APL patients who achieved complete remission (CR) and completed the three consolidation cycles were enrolled into the analysis. Out of 2670 APL patients, there were 118 (4.4%) who developed s-NPLs with the median latency period (between first CR and diagnosis of s-NPL) of 48.0 months (range 2.8-231.1): 43.3 (range: 2.8-113.9) for s-MDS/AML and 61.7 (range: 7.1-231.1) for solid tumour. The 5-year CI of all s-NPLs was of 4.43% and 10 years of 7.92%. Among s-NPLs, there were 58 cases of s-MDS/AML, 3 cases of other hematological neoplasms, 57 solid tumours and 1 non-identified neoplasm. The most frequent solid tumour was colorectal, lung and breast cancer. Overall, the 2-year OS from diagnosis of s-NPLs was 40.6%, with a median OS of 11.1 months. Multivariate analysis identified age of 35 years (hazard ratio = 0.2584; p < 0.0001) as an independent prognostic factor for s-NPLs. There were no significant differences in CI of s-NPLs at 5 years between chemotherapy-based vs chemotherapy-free regimens (hazard ratio = 1.09; p = 0.932). Larger series with longer follow-up are required to confirm the potential impact of ATO+ATRA regimens to reduce the incidence of s-NPLs after front-line therapy for APL.

Fragility scales are intended to help in therapeutic decisions. Here, we asked if the fragility assessment in MM patients ≥ 75 years old qualified for treatment by the local physician correlates with the choice of treatment: a two- or three-drug regimens. Between 7/2018 and 12/2019, we prospectively enrolled 197 MM patients at the start of treatment from the 13 Polish Myeloma Group centers. The data to assess fragility were prospectively collected, but centrally assessed fragility was not disclosed to the local center. The activity of daily living (ADL) could be assessed in 192 (97.5%) and was independent in 158 (80.2%), moderately impaired in 23 (11.7%), and 11 (5.6%) in completely dependent. Patients with more than three comorbidities made up 26.9% (53 patients). Thus, according to the Palumbo calculator, 43 patients were in the intermediate fitness group (21.8%), and the rest belonged to the frailty group (153, 77.7%). Overall, 79.7% of patients (157) received three-drug regimens and 20.3% (40) received two-drug regimens. In each ECOG group, more than three out of four patients received three-drug regimens. According to the ADL scale, 82.3% of the independent 65.2% of moderately impaired, and 81.8% of the dependent received three-drug regimens. Out of 53 patients with at least four comorbidities, 71.7% received three-drug regimens, and the rest received two-drug regimens. Thirty-four patients from the intermediate fit group (79.0%), and 123 (79.9%) from the frail group received three-drug regimens. Early mortality occurred in 25 patients (12.7%). No one discontinued treatment due to toxicity. To conclude, MM patients over 75 are mainly treated with triple-drug regimens, not only in reduced doses, regardless of their frailty scores. However, the absence of prospective fragility assessment did not negatively affect early mortality and the number of treatment discontinuations, which brings into question the clinical utility of current fragility scales in everyday practice.
RESUMEN
PURPOSE: New therapies are needed for relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma. This phase 1b, open-label trial evaluated two anti-CD20-based triplet combinations. METHODS: Patients with R/R follicular lymphoma (FL; n = 13) were treated with obinutuzumab, atezolizumab, and polatuzumab vedotin (G-atezo-pola; 1.4 mg/kg/1.8 mg/kg) and patients with R/R diffuse large B-cell lymphoma (DLBCL; n = 23) received rituximab (R)-atezo-pola. The primary efficacy endpoint was complete response (CR) at end of induction (EOI) by PET-CT (investigator assessed; modified Lugano 2014 criteria). Safety endpoints were also assessed. RESULTS: 13 FL patients were treated and evaluable for safety; 2/23 DLBCL patients did not receive treatment and were not included in the safety population. Median observation time was 23.3 and 5.7 months in the FL and DLBCL cohorts, respectively. At EOI, CR rates in FL patients treated with G-atezo-pola at pola doses of 1.4 mg/kg (N = 3) and 1.8 mg/kg (N = 7) were 33% and 14%, respectively. In DLBCL patients receiving R-atezo-pola, the CR rate at EOI was 13%. In the FL cohort, 62% of patients experienced a grade 3-5 adverse event (AE; including two deaths) and 31% developed a serious AE (SAE). In DLBCL patients, R-atezo-pola was associated with a lower incidence of grade 3-5 AEs (24%; one death) and SAEs (10%). In both cohorts, the most common grade 3-5 AEs were hematologic toxicities. CONCLUSION: Based on these safety issues, considered as related specifically to G-atezo-pola, and limited efficacy, no further development of either combination is planned. TRIAL REGISTRATION: NCT02729896; Date of registration: April 6, 2016.

OBJECTIVE: To investigate the prevalence of histopathological subtypes, the clinical stage at presentation and treatment modalities in Polish patients with orbital lymphoma (OL) and to determine prognostic outcomes. METHODS: The retrospective study of 107 patients with OL treated in a 14-year period in Polish hematological centers. The analysis included histopathological subtype, disease clinical advancement, treatment modalities, progression-free survival (PFS), and overall survival (OS). RESULTS: The median patient age was 60 years (range 51-71). Mucosa-associated lymphoid tissue (MALT) lymphoma accounted for slightly more than half of all cases of orbital lymphoma (51%). The second most common subtype was diffuse large B-cell lymphoma (DLBCL) (29%). Primary orbital lymphoma was diagnosed in 48% of all patients. According to the Ann Arbor, localized stage IE of orbital lymphoma was diagnosed only in 39% of all patients. Systemic involvement was observed in more than half of all patients (52%). The median follow-up period was 30 months (range 0-160 months). Patients with non-MALT lymphoma had a significantly inferior PFS compared to patients with MALT lymphoma, (p = 0.047). Patients with primary orbital lymphoma had a superior PFS compared to patients with secondary orbital lymphoma [median PFS 104.5 months vs. 33.4 months], (p = 0.069). Younger patients with MALT lymphoma were characterized by superior PFS (median PFS not reached) compared to other studied subgroups of patients (older patients with MALT lymphoma, younger and older non-MALT lymphoma patients) with a median PFS of 30.5, 32.2, 32.6 months respectively (p = 0.039). Patients treated with chemotherapy alone had inferior PFS compared to patients treated with combined therapies (p = 0.034). The median PFS across patients who received chemotherapy alone was 23.7 months, whereas across other patients was 73.9 months. CONCLUSIONS: Secondary lymphoma accounts for more than half of the orbital lymphoma in Polish population. The advanced clinical stage of the disease (non-IE according to Ann Arbor) concerns two-thirds of the overall population of patients with orbital lymphomas and one-third of MALT lymphoma patients. The high incidence of advanced stages of orbital lymphoma may indicate the need for combined treatment. Combined orbital lymphoma treatment is associated with superior PFS compared to chemotherapy alone in overall population of patients with orbital lymphoma.

The efficacy of salvage treatment of diffuse large B-cell lymphoma (DLBCL) patients who relapse or progress (rrDLBCL) after initial therapy is limited. Efficacy and safety of ofatumumab with iphosphamide, etoposide and cytarabine (O-IVAC) was evaluated in a single-arm study. Dosing was modified for elderly patients. Patients received up to six cycles of treatment. The primary end-point was the overall response rate (ORR). Patients were evaluated every two cycles and then six and 12 months after treatment. Other end-points included progression-free survival (PFS), event-free survival (EFS), overall survival (OS) and safety. Seventy-seven patients received salvage treatment with O-IVAC. The average age was 56.8 years; 39% had an Eastern Cooperative Oncology Group (ECOG) performance status of at least 3; 78% had disease of Ann Arbor stage 3 or 4; 58% received one or more prior salvage therapies. The ORR for O-IVAC was 54.5%. The median duration of study follow-up was 70 months. The median PFS and EFS were 16.3 months each. The median OS was 22.7 months. Age, ECOG performance status and the number of prior therapy lines were independent predictors of survival. Treatment-related mortality was 15.5%. O-IVAC showed a high response rate in a difficult-to-treat population and is an attractive treatment to bridge to potentially curative therapies.

Phosphoinositide 3-kinase-δ (PI3Kδ) inhibitors are active in lymphoid malignancies, although associated toxicities can limit their use. Umbralisib is a dual inhibitor of PI3Kδ and casein kinase-1ε (CK1ε). This study analyzed integrated comprehensive toxicity data from 4 open-label, phase 1 and 2 studies that included 371 adult patients (median age, 67 years) with relapsed/refractory non-Hodgkin lymphoma (follicular lymphoma [n = 147]; marginal zone lymphoma [n = 82]; diffuse large B-cell lymphoma/mantle cell lymphoma [n = 74]; chronic lymphocytic leukemia [n = 43]; and other tumor types [n = 25]) who were treated with the recommended phase 2 dose of umbralisib 800 mg or higher once daily. At data cutoff, median duration of umbralisib treatment was 5.9 months (range, 0.1-75.1 months), and 107 patients (28.8%) received umbralisib for ≥12 months. Any-grade treatment-emergent adverse events (AEs) occurred in 366 (98.7%) of 371 patients, with the most frequent being diarrhea (52.3%), nausea (41.5%), and fatigue (31.8%). Grade 3 or higher treatment-emergent AEs occurred in 189 (50.9%) of 371 patients and included neutropenia (11.3%), diarrhea (7.3%), and increased aminotransferase levels (5.7%). Treatment-emergent serious AEs occurred in 95 (25.6%) of 371 patients. AEs of special interest were limited and included pneumonia (29 of 371 [7.8%]), noninfectious colitis (9 of 371 [2.4%]), and pneumonitis (4 of 371 [1.1%]). AEs led to discontinuation of umbralisib in 51 patients (13.7%). Four patients (1.1%) died of AEs, none of which was deemed related to umbralisib. No cumulative toxicities were reported. The favorable long-term tolerability profile and low rates of immune-mediated toxicities support the potential use of umbralisib for the benefit of a broad population of patients with lymphoid malignancies.

PURPOSE: Phosphatidylinositol-3-kinase (PI3K) inhibitors have shown activity in relapsed or refractory (R/R) indolent non-Hodgkin lymphoma (iNHL). PI3K inhibitors have been hampered by poor long-term tolerability and toxicity, which interfere with continuous use. Umbralisib, a dual inhibitor of PI3Kδ/casein kinase-1ε, exhibits improved selectivity for PI3Kδ compared with other PI3K inhibitors. This phase IIb trial was designed to evaluate the efficacy and safety of umbralisib in patients with R/R iNHL. PATIENTS AND METHODS: In this multicohort, open-label, phase IIb study, 208 patients with R/R marginal zone, follicular, or small lymphocytic lymphoma (MZL, FL, or SLL) unresponsive to prior treatments (≥ 1 MZL; ≥ 2 FL/SLL), including ≥ 1 anti-CD20-based therapy, were administered umbralisib 800 mg orally once daily until disease progression, unacceptable toxicity, or study withdrawal. Primary end point is overall response rate; secondary end points include time to response, duration of response, progression-free survival, and safety. RESULTS: The median follow-up is 27.7 months (efficacy) and 21.4 months (safety). The overall response rate was 47.1%, and tumor reduction occurred in 86.4% of patients. The median time to response was 2.7-4.6 months. The median duration of response was not reached for MZL, 11.1 months for FL, and 18.3 months for SLL. Median progression-free survival was not reached for MZL, 10.6 months for FL, and 20.9 months for SLL. At least one grade ≥ 3 treatment-emergent adverse event (TEAE) was reported in 53.4% of patients. TEAEs led to umbralisib discontinuation in 32 patients (15.4%). A total of 31 patients (14.9%) discontinued because of a treatment-related adverse event. Grade ≥ 3 TEAEs reported in ≥ 10% of patients: neutropenia (11.5%) and diarrhea (10.1%). Increased ALT/AST (grade ≥ 3) occurred in 6.7%/7.2% of patients. CONCLUSION: Umbralisib achieved meaningful clinical activity in heavily pretreated patients with iNHL. The safety profile was manageable, with a relatively low incidence of immune-mediated toxicities and adverse event-related discontinuations.

The optimal salvage therapy in relapsed/refractory Hodgkin lymphoma (R/R HL) has not been defined so far. The goal of this multicenter retrospective study was to evaluate efficacy and safety of BGD (bendamustine, gemcitabine, dexamethasone) as a second or subsequent line of therapy in classical R/R HL. We have evaluated 92 consecutive R/R HL patients treated with BGD. Median age was 34.5 (19-82) years. Fifty-eight patients (63%) had received 2 or more lines of chemotherapy, 32 patients (34.8%) radiotherapy, and 21 patients (22.8%) an autologous hematopoietic stem cell transplantation (autoHCT). Forty-four patients (47.8%) were resistant to first line of chemotherapy. BGD therapy consisted of bendamustine 90 mg/m2 on days 1 and 2, gemcitabine 800 mg/m2 on days 1 and 4, dexamethasone 40 mg on days 1-4. Median number of BGD cycles was 4 (2-7). The following adverse events ≥ 3 grade were noted: neutropenia (22.8%), thrombocytopenia (20.7%), anemia (15.2%), infections (10.9%), AST/ALT increase (2.2%), and skin rush (1.1%). After BGD therapy, 51 (55.4%) patients achieved complete remission, 23 (25%)-partial response, 7 (7.6%)-stable disease, and 11 (12%) patients experienced progression disease. AutoHCT was conducted in 42 (45.7%) patients after BGD therapy, and allogeneic HCT (alloHCT) in 16 (17.4%) patients. Median progression-free survival was 21 months. BGD is a highly effective, well-tolerated salvage regimen for patients with R/R HL, providing an excellent bridge to auto- or alloHCT.

BACKGROUND/AIM: To study the long-term clinical efficacy and tolerability of ibrutinib monotherapy in real-world relapsed and refractory chronic lymphocytic leukemia (RR-CLL) patients outside clinical trials. PATIENTS AND METHODS: Clinical data of 171 RR-CLL patients treated with ibrutinib were collected within the observational study of the Polish Adult Leukemia Study Group. RESULTS: Median patient age was 64 years. Patients were pretreated with 3 (1-10) median lines of therapy, while 42 (24.6%) had 17p deletion. The median observation time was 40 months (range=1-59 months), while median ibrutinib monotherapy reached 37.5 months (range=0.4-59.2 months). Response was noted in 132 (77.2%) patients. The estimated 5-year progression-free survival (PFS) and overall survival (OS) rates were 61.1% (95%CI=49.3-70.9%) and 56.8% (95%CI=45.6-66.6%), respectively. At the time of analysis 97 (56.7%) remained under ibrutinib monotherapy. CONCLUSION: Ibrutinib is clinically effective and tolerable as a monotherapy in real-world RR-CLL patients.

Comorbidities impair the prognosis of diffuse large B-cell lymphoma (DLBCL). Type 2 diabetes mellitus (DMT2) increases the risk of other comorbidities, e.g., heart failure (HF). Thus, we hypothesized that pre-existing DMT2 may negatively affect the outcome of DLBCL. To verify this, DLBCL patients treated with (R)-CHOP were enrolled. 469 patients were eligible, with a median age of 57 years; 356 patients had advanced-stage DLBCL. 126 patients had high-intermediate and 83 high-risk international prognostic index (IPI). Seventy-six patients had DMT2, 46 HF; 26 patients suffered from both DMT2 and HF. In the analyzed group DMT2 or HF significantly shortened overall survival (OS) and progression free survival (PFS): the 5-year OS for patients with DMT2 was 64% vs 79% and for those with HF: 49% vs 79%. The 5-year PFS for DMT2 was 50.6% vs 62.5% and for HF 39.4% vs 63.2%. The relapse/progression incidence was comparable between groups; the non-relapse/progression mortality (NRPM) was significantly higher solely in DMT2 patients (5-year NRPM 22.5% vs 8.4%). The risk of death was higher in patients with higher IPI (HR = 1.85) and with DMT2 (HR = 1.87). To conclude, pre-existing DMT2, in addition to a higher IPI and HF, was a negative predictor for OS and PFS.

R-CVP (cyclophosphamide, vincristine, prednisone) and R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone + rituximab) are immunochemotherapy regimens frequently used for remission induction of indolent non-Hodgkin lymphomas (iNHLs). Rituximab maintenance (RM) significantly improves progression-free survival (PFS) in patients with complete/partial remission (CR/PR). Here we report the final results of a randomized study comparing R-CVP to R-CHOP both followed by RM. Untreated patients in need of systemic therapy with symptomatic and progressive iNHLs including follicular (FL) and marginal zone lymphoma (MZL), mucosa-associated lymphoid tissue (MALT), small lymphocytic (SLL), and lymphoplasmacytic (LPL) lymphoma were eligible. Patients were randomized to receive R-CVP or R-CHOP for eight cycles or until complete response (CR). All patients with CR/PR (partial response) received RM 375 mg/m2 q 2 months for 12 cycles. Primary endpoint was event-free survival (EFS). Two-hundred and fifty patients [FL 42%, MZL/MALT 38%, LPL/ Waldenström Macroglobulinaemia (WM) 11%, SLL 9%] were enrolled and randomized (R-CHOP: 127, R-CVP: 123). Median age was 56 years (21-85), 44% were male, 90% were in stage III-IV, 43% of FL patients had a Follicular Lymphoma International Prognostic Index (FLIPI) score ≥3, and 33·4% of all patients had an IPI score ≥3. At the end of induction treatment, the CR/PR rate was 43·6/50·9% and 36·3/60·8% in the R-CHOP and R-CVP groups (P = 0·218) respectively. After a median follow-up of 67, 66, and 70 months, five-year EFS was 61% vs. 56% (not significant), progression-free survival (PFS) was 71% vs. 69% (not significant) and overall survival (OS) was 84% vs. 89% in the R-CHOP vs. the R-CVP arm respectively. Grade III/IV adverse events (65 vs. 22) occurred in 40 (33·1%) and 18 (15·3%) patients, P = 0·001; neutropenia in 16 (11·6%) and 4 (3·4%) patients, P = 0·017; infection in 14 (10·7%) and 3 (2·5%) patients,; P = 0·011; and a second neoplasm in three versus seven patients., in the R-CHOP and the R-CVP groups respectively. This multicentre randomized study with >five-year follow-up shows similar outcome in patients with indolent lymphoma in need of systemic therapy treated with R-CVP or R-CHOP immunochemotherapy and rituximab maintenance in both arms. The minor toxicity of the R-CVP regimen makes it a reasonable choice for induction treatment, leaving other active agents like doxorubicin or bendamustin for second-line therapy.

We present the results of a prospective, non-randomized phase 2 trial in which 253 AML patients (pts) under 60 years old received DAC (Daunorubicin + AraC + Cladribine) as first induction followed by CLAM (Cladribine + AraC + Mitoxantrone) as early second induction on day 16 based on bone marrow (BM) blasts on day 14 (D14). The CR/CRi rate after a single course of DAC was 83% for pts with D14 BM blasts less than 10%. Forty-six pts had >10% BM blasts on D14, of whom 35 received CLAM with rates of CR/CRi 60% and early death (ED) 23%. The remaining 11 pts were not fit to receive CLAM, with rates of CR/CRi 28%, PR 18%, and ED 18%. Median OS was 7.2 versus 7.5 months, respectively. The overall CR/CRi rate was 77% after the first induction, with final CR/CRi rate 80% after DAC reinduction for pts who achieved PR with initial DAC course. CLAM used as early second induction might improve CR/CRi rates for younger AML pts with poor early response to DAC induction, but may be associated with higher mortality.

PURPOSE: Daratumumab is a promising new agent for relapsed/refractory multiple myeloma (RRMM). However, there are limited data on its clinical activity and tolerability in the real-world patients. The purpose of this study is to determine the efficacy and toxicity profile of daratumumab monotherapy in the real-life setting. PATIENTS AND METHODS: Thirty RRMM patients treated with daratumumab who had previously received at least three treatment lines including a proteasome inhibitor and an immunomodulatory drug or had been double refractory (DRMM) were included to the Polish Myeloma Group observational study. RESULTS: The objective response rate to daratumumab was 42.8%. Median progression-free survival (PFS) and overall survival reached 9.5 and 13.8 months, respectively. Importantly, patients with DR-MM had a significantly shorter PFS than other patients (median PFS of 4.1 vs. 12.1 months). Daratumumab was generally well tolerated, however two patients had their therapy interrupted due to adverse events. CONCLUSION: Daratumumab monotherapy has significant activity and good tolerance in heavily pretreated RRMM patients.

Polish Lymphoma Research Group performed a phase-II trial to test whether 90Y ibritumomab tiuxetan radioimmunotherapy (Y90) may constitute an alternative consolidation for mantle cell lymphoma patients unfit for high-dose therapy. Forty-six patients were consolidated with Y90 following response to the 1st (n = 34) or 2nd line (n = 12) (immuno)chemotherapy. Majority of the patients had advanced disease (stage IV and presence of B-symptoms in 85% and 70%, respectively) and high MIPI (5.8, range 4-7). Consolidation with Y90 increased the complete remission (CR) rate obtained by the 1st line therapy from 41% to 91% and allowed for median PFS of 3.3 and OS of 6.5 years. In the first relapse, CR rate increased from 16% to 75%, while median PFS and OS totaled 2.2 and 6.5 years, respectively. At 8 years, 30% of patients, consolidated in the 1st line CR were alive, without relapse. Toxicity associated with Y90 is manageable, more severe after fludarabine-based regimens.

Richter transformation (RT) of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) to Hodgkin lymphoma (HL) is a rare and unexpected event in the course of the disease and data on this phenomenon is still limited. To better understand the clinical and histological characteristics and the outcomes of HL variant of RT (HvRS) the Polish Lymphoma Research Group performed a nationwide survey which identified 22 patients with histologically proven HvRS diagnosed between 2002 and 2016. There were 16 (73%) males. The median age at CLL/SLL and HvRS diagnosis was 59 (39-77) and 64 (40-77) years, respectively. The median interval between CLL/SLL and HvRS diagnosis was 38 months (range: 0-187). All patients had an advanced stage HL, and majority, 17 (77%), presented with B symptoms. The predominant subtypes of HL were nodular sclerosis (12; 55%) and mixed cellularity (9; 41%). Eighteen patients received non-palliative treatment, including 13 who received driamycin, bleomycin, vinblastine, and dacarbazine (ABVD) regimen first line. Objective response was: 50%, with 33% complete remissions (61% and 46% for ABVD, respectively). Median overall survival reached 13.3 months (95% CI, 3.7-NA). The only adverse prognostic factor for survival was a higher number (≤1 versus ≥2) of prior lines of treatment given for CLL/SLL with HR 3.57 (95% CI, 1.16-10.92). We conclude, HvRS harbors a poor prognosis, especially in patients heavily pretreated for CLL/SLL. Response to standard first-line anti-HL chemotherapy is unsatisfactory, and new agents should be tested to improve the outcome.

BACKGROUND: Myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML) patients, including those treated with azacitidine, are at increased risk for serious infections. The aim of our study was to identify patients with higher infectious risk at the beginning of azacitidine treatment. PATIENTS AND METHODS: We performed a retrospective evaluation of 298 MDS/CMML/AML patients and included in the analysis 232 patients who completed the first 3 cycles of azacitidine therapy or developed Grade III/IV infection before completing the third cycle. RESULTS: Overall, 143 patients (62%) experienced serious infection, and in 94 patients (41%) infection occurred within the first 3 cycles. The following variables were found to have the most significant effect on the infectious risk in multivariate analysis: red blood cell transfusion dependency (odds ratio [OR], 2.38; 97.5% confidence interval [CI], 1.21-4.79), neutropenia <0.8 × 109/L (OR, 3.03; 97.5% CI, 1.66-5.55), platelet count <50 × 109/L (OR, 2.63; 97.5% CI, 1.42-4.76), albumin level <35 g/dL (OR, 2.04; 97.5% CI, 1.01-4.16), and Eastern Cooperative Oncology Group performance status ≥2 (OR, 2.19; 97.5% CI, 1.40-3.54). Each of these variables is assigned 1 point, and the combined score represents the proposed Azacitidine Infection Risk Model. The infection rate in the first 3 cycles of therapy in lower-risk (0-2 score) and higher-risk (3-5 score) patients was 25% and 73%, respectively. The overall survival was significantly reduced in higher-risk patients compared with the lower-risk cohort (8 vs. 29 months). CONCLUSION: We selected a subset with high early risk for serious infection and worse clinical outcome among patients treated with azacitidine.

We retrospectively analyzed long-term disease outcome of 350 elderly Hodgkin Lymphoma (eHL) patients treated with ABVD/ABVD-like regimen enrolled in the PLRG-R9 study between 2001 and 2013 in Poland. Complete remission was reported for 73% of early (ES) and 61% advanced stage (AS) patients. Nine (10%) ES and 56 (20%) AS patients have died. With the median follow-up of 36 (1-190) months, 3-year EFS and OS was 0.74 (95%CI: 0.63-0.85) and 0.90 (95%CI: 0.82-0.98) for ES; 0.51 (95%CI: 0.44-0.57), and 0.81 (95%CI: 0.75-0.86) for AS patients, respectively. For ES patients, Cox regression revealed ECOG <2 and age >70 as predictive for inferior OS and EFS. For AS patients, the most predictive for OS was the presence of cardiovascular disorders (CVD) (p = .00044), while for EFS four factors were significantly associated with a poor outcome: ECOG< 2, age >70 years, CVD and extranodal disease. In conclusion, CVD significantly impacts outcomes of ABVD-treated advanced eHL patients.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is one of the aggressive rare hematopoietic malignancies with predilection to the skin, primarily found in adults. The precise incidence of BPDCN is difficult to estimate due to constantly changing nomenclature and lack of precise defining criteria prior to the 2008 WHO classification system. There are not many cases described in the literature, what makes the diagnostic process challenging. Skin lesions such as erythematous infiltrates and nodules are usually the first manifestation of the disease. Therefore, in doubtful diagnostic cases, dermatologists should perform histopathological and immunohistochemistry examinations along with hematological and oncological cooperation, as early diagnosis and appropriate treatment is essential for improvement of the disease course. This analysis, despite the small number of patients may provide useful information on the clinical and histopathological features of this rare malignancy.
RESUMEN
We report a multicentre retrospective study that analysed clinical characteristics and outcomes in 117 patients with primary plasma cell leukaemia (pPCL) treated at the participating institutions between January 2006 and December 2016. The median age at the time of pPCL diagnosis was 61 years. Ninety-eight patients were treated with novel agents, with an overall response rate of 78%. Fifty-five patients (64%) patients underwent upfront autologous stem cell transplantation (ASCT). The median follow-up time was 50 months (95% confidence interval [CI] 33; 76), with a median overall survival (OS) for the entire group of 23 months (95% CI 15; 34). The median OS time in patients who underwent upfront ASCT was 35 months (95% CI 24·3; 46) as compared to 13 months (95% CI 6·3; 35·8) in patients who did not receive ASCT (P = 0·001). Multivariate analyses identified age ≥60 years, platelet count ≤100 × 109 /l and peripheral blood plasma cell count ≥20 × 109 /l as independent predictors of worse survival. The median OS in patients with 0, 1 or 2-3 of these risk factors was 46, 27 and 12 months, respectively (P < 0·001). Our findings support the use of novel agents and ASCT as frontline treatment in patients with pPCL. The constructed prognostic score should be independently validated.
