Currently, there is no consensus regarding optimal front-line treatment for younger high-risk patients with large B cell lymphoma. American recommendations list only R-CHOP as standard, while ...European also include R-ACVBP and R-CHOEP14. We have been routinely using the latter regimen at our institution since 2011 and performed this retrospective real-life single-center study to analyze outcomes. Between September 2011 and April 2019, 66 newly diagnosed patients aged 18 to 60 years with B-large cell lymphoma and high-risk age-adjusted International Prognostic Index score were scheduled to receive 6 or 8 cycles of bi-weekly chemoimmunotherapy with cyclophosphamide, doxorubicin, vincristine, etoposide, steroids, and rituximab (R-CHOEP14). After a median follow-up of 4.7 years, the estimated 3-year progression-free survival was 87% (95% CI 80–96%) and 3-year overall survival 90% (95% CI 83–98%). Grade ≥ 3 hematological side effects occurred in 83% and infectious in 41% of patients; one patient died of toxicity. Grade ≥ 2 cardiac toxicity occurred in 21% of patients, more frequently than previously reported. The cumulative 5-year risk of congestive heart failure with all-cause mortality as the competing risk was 17%. R-CHOEP14 is a very effective and manageable regimen for younger high-risk patients with B-large cell lymphoma, but the risk of cardiotoxicity warrants further investigations.
: eBEACOPP is the most effective chemotherapy regimen for younger patients with early unfavorable (EU) and advanced-stage (AS) Hodgkin lymphoma (HL), albeit with significant toxicities. The ...14-day/cycle prednisone course contributes to side effects, including osteoarticular events like avascular bone necrosis (AVN). Our center has been using eBEACOPP since 2009 for AS and 2014 for EU patients. In 2016, we reduced prednisone treatment to 7-10 days to lessen AVN risk. We analyzed the effects of this approach.
: We retrospectively collected data on patients who received at least two cycles of eBEACOPP for first-line HL treatment.
: A total of 162 patients (33 EU, 129 AS) were included. Their median age was 31 (range 19-59 years), and 88 were males. A total of 94 patients received full corticosteroid courses, and 68 received reduced corticosteroid courses. The overall response rate (ORR) was 98%. Different corticosteroid dosings had no significant effect on ORR, febrile neutropenia episodes, or hospital admissions. After a median follow-up (mFU) of 58 months, the 5yPFS for the entire cohort was 98% vs. 95% for the standard course vs. the short corticosteroids course, respectively (
= 0.37), while the 5yOS was 98% vs. 99% for the standard course vs. short corticosteroids course, respectively (
= 0.87). In AS patients intended to be treated with six eBEACOPP cycles, 5yPFS and 5yOS were 100% vs. 97% and 100% vs. 99% for standard vs. short corticosteroid courses, respectively (
= 0.56 and
= 0.17). In EU patients, 5yPFS was 97% (standard) vs. 95% (short) (
= 0.98) and 5yOS 100% vs. 93.3% (
= 0.87). Osteoarticular events were numerically lower in patients receiving the shorter prednisone course, both in the whole cohort and in the subgroup of patients treated with six cycles of eBEACOPP, but this difference failed to reach statistical significance.
: eBEACOPP provides excellent and durable first-line disease control. Shortening the corticosteroid course does not compromise efficacy, potentially reducing toxicity. However, longer follow-ups and larger studies are needed for confirmation.
Background
Escalated BEACOPP (eBEACOPP) is an effective but fairly toxic regimen for the treatment of Hodgkin lymphoma (HL). Avascular necrosis (AVN) of femoral head was previously reported to ...increase in patients treated with eBEACOPP, but so far, no systematic analysis of its frequency has been published.
Aims
To analyse the frequency and identify possible risk factors for AVN development in patients treated with eBEACOPP.
Methods
We identified 26 patients treated with eBEACOPP for newly diagnosed high‐risk advanced‐stage HL, 25 of whom were alive at the time of study. All patients were invited to participate in a cross‐sectional study; 17 patients responded and were evaluated by magnetic resonance imaging and orthopaedic examination.
Results
Six patients (35.3%) were diagnosed with AVN after receiving eBEACOPP treatment. AVN was not correlated with age, gender, number of received eBEACOPP cycles, irradiation therapy or cumulative dose of steroids administered. There were significantly more cases of AVN in patients receiving methylprednisolone than prednisone (P = 0.01).
Conclusion
The use of methylprednisolone was shown to be a risk factor for the development of AVN in patients treated with eBEACOPP and should not be the corticosteroid of choice in the treatment of patients with HL.
The influence of the germinal-center B-cell (GCB) and the non-GCB phenotypes of diffuse large B-cell lymphoma (DLBCL) on the outcome of 92 patients treated with cyclophosphamide, doxorubicin, ...vincristine, and prednisone (CHOP) or CHOP-like chemotherapy, with or without rituximab was determined in this study. The differentiation between the GCB and non-GCB types was arrived at by immunohistochemistry using previously published criteria. Thirty-nine patients had the GCB and 53 had the non-GCB type of DLBCL. Forty-nine patients were treated with rituximab and chemotherapy; 43 were treated with chemotherapy alone. The GCB and non-GCB group did not differ in their international prognostic index factors and score, presence of bulky disease, or frequency of rituximab treatment. Median follow-up of the surviving patients was carried out for 37 months. There was no difference between the GCB and non-GCB groups in both overall response rates (67 vs. 70%, respectively) and estimated rates of 3-year event-free (46 vs. 49%, respectively) and overall (54 vs. 56%, respectively) survival. In addition, no differences of the outcomes were observed between the subgroups treated with or without rituximab. The patients of this study with immunohistochemically determined GCB-type DLBCL did not have an improved prognosis, irrespective of whether they had received rituximab or not.
Disease- and treatment-mediated immunodeficiency might render SARS-CoV-2 vaccines less effective in patients with hematologic diseases. We performed a prospective non-interventional study to evaluate ...humoral response after one and two doses of mRNA-1273, BNT162b2, or ChAdOx1 nCoV-19 vaccine in 118 patients with different malignant or non-malignant hematologic diseases from three Croatian treatment centers. An electrochemiluminescent assay was used to measure total anti-SARS-CoV-2 S-RBD antibody titers. After one vaccine dose, 20/66 (33%) achieved seropositivity with a median antibody titer of 6.1 U/mL. The response rate (58/90, 64.4%) and median antibody titer (>250 U/mL) were higher after two doses. Seropositivity varied with diagnosis (overall p < 0.001), with the lowest rates in lymphoma (34.6%) and chronic lymphocytic leukemia (52.5%). The overall response rate in chronic myeloproliferative neoplasms (CMPN) was 81.3% but reached 100% in chronic myeloid leukemia and other non-myelofibrosis CMPN. At univariable analysis, age > 67 years, non-Hodgkin’s lymphoma, active treatment, and anti-CD20 monoclonal antibody therapy increased the likelihood of no vaccine response, while hematopoietic stem cell recipients were more likely to respond. Age and anti-CD20 monoclonal antibody therapy remained associated with no response in a multivariable model. Patients with the hematologic disease have attenuated responses to SARS-CoV-2 vaccines, and significant variations in different disease subgroups warrant an individualized approach.
Primary cutaneous follicle center lymphoma is an indolent primary cutaneous B-cell lymphoma originating from the follicle center cells, composed of a combination of centrocytes (small and large ...cleaved cells) and centroblasts (large noncleaved cells) with a follicular, follicular/diffuse, or diffuse growth pattern. Lesions are mostly located on the head, neck and trunk. A case is presented of a 56-year-old male patient with primary cutaneous follicle center lymphoma, with lesions involving the skin of the back, shoulders, presternal area and right forearm. As the patient presented a disseminated cutaneous form of the disease that involved several anatomical regions, complete work-up was followed by superficial fractionated radiotherapy of eight fields in VI expositions, with total irradiation dose of 1400 cGy upon the following fields: right and left pectoral region, left and right shoulders, right suprascapular region, and proximal third of the right forearm. Total irradiation dose applied upon each field for the lesions located on the left and right side of the back was 1500 cGy. This therapy resulted in significant reduction of visible tumor. The patient was regularly followed up on outpatient basis for 12 months of radiotherapy, being free from local recurrence and systemic spread of the disease.
Chronic kidney dysfunction is associated with increased mortality in multiple cancer types. Preliminary evidence suggests the same to be true for B-large cell lymphomas (B-LCL). To analyze the ...relationship of glomerular filtration rate (GFR) and outcome of B-LCL in detail we collected data on outcomes of 285 consecutive patients with newly diagnosed B-LCL treated at our institution with standard rituximab-containing regimens who did not have preexisting kidney disease or urinary tract obstruction at presentation. Median age was 59, range 18 to 87, 145 were male and 140 females. Forty-four had GFR < 60 mL/min, 123 had 60 to 90 mL/min, and 118 > 90 mL/min. Median follow-up of surviving patients was 49 months and estimated 3-year survival 76%. In univariate analysis age (P < .001), GFR (P = .014), stage (P < .001), performance status (P = .044), chemotherapy regimen (P < .01), and international prognostic index (IPI) (P < .001) were statistically significant prognostic factors. In multivariate analysis, age and GFR remained the only independent prognostic factors. Subtracting 1 from the IPI score of patients who had GFR > 90 mL/min and IPI > 1 resulted in a prognostic index that divides patients into 3 prognostic groups (low risk = 0-1, intermediate risk = 2-3 and high risk = 4-5) with an acceptable patient distribution frequency (38%, 39%, and 23%, respectively) and improved statistical significance and separation in comparison to IPI (5-year survival rates of 92%, 74%, and 42%, respectively). GFR is an important independent prognostic factor for B-LCL that should be taken into account in clinical decision making and data analysis and probably be incorporated in prognostic indices.
In a study analyzing the difference between Philadelphia chromosome–negative patients with myeloproliferative neoplasms with and without thrombosis, we found a significant difference in the risk ...factors for arterial and venous thrombosis in myeloproliferative neoplasm (MPN) patients, as well as between different subtypes of MPN, according to leukocyte and platelet count, V617F burden allele, and cardiovascular risk factors.
Thrombosis is the most common complication in Philadelphia chromosome negative (Ph−) myeloproliferative neoplasms patients.
In a cohort of 258 Ph− myeloproliferative neoplasm patients, the difference between patients with and without thrombosis was analyzed according to genetic thrombophilia factors, JAK2 V617F status and burden allele, blood count, cardiovascular risk factors and age. Patients were also divided in polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) subgroups as well as by the type of thrombosis.
Analysis of cardiovascular risk factors regarding arterial thrombosis showed that PV patients with thrombosis had higher incidence of diabetes (P = .030), ET patients more often had hypertension (P = .003) and hyperlipidemia (P = .005), while PMF patients had hyperlipidemia (P = .046) and at least one cardiovascular risk factor (P = .044). Moreover, leukocytes > 18 × 109/L and V617F burden allele > 25.7% were statistically significantly different in PV patients (P = .019 and borderline significant at P = .055, respectively), while in ET patients leukocytes > 9.2 × 109/L (P < .001) and age at diagnosis of > 55 years were statistically significantly different (P = .002). PMF patients with V617F burden allele ≤ 34.8% were more prone to thrombosis (P = .032). When comparing patients with and without venous thrombosis, cutoff value of V617F burden allele > 90.4% was significant for PV patients with thrombosis (P = .036), as was > 56.7% for PMF patients with thrombosis (P = .046). Platelets ≤ 536 × 109/L and age at diagnosis > 54 years showed statistically significant difference for ET patients with thrombosis (P = .015 and P = .041, respectively).
On the basis of our results, a new scoring system for thrombosis risk in PV could be made, while PMF prognostic model may be expanded for better recognition of potential thrombotic risk factors.
