ABSTRACT

Background. The present paper discusses feasibility of first- and second-line therapies as well as the significance of different risk factors in the population of all patients with newly diagnosed Hodgkin’s lymphomas (HL) in a 14-year period based on the data of Volgograd regional registry.

Materials & Methods. During the period 2003 to 2017 the population registry of Department of Hematology of Volgograd Regional Clinical Oncology Dispensary included the data of all the patients with newly diagnosed HL (n = 622): 272 (44 %) men and 350 (56 %) women aged 18 to 84 years (mean age 38 years, median age 33 years). There were 97 (16 %) patients with early stages and without risk factors, 165 (27 %) patients with early stages and risk factors, 360 (59 %) patients with advanced stages, 308 (50 %) patients with toxic symptoms (stage B), and 179 (29 %) patients with bulky tumor lesions (≥ 10 cm). ABVD treatment regimen was administered in 190 (30.5 %) patients, increased-dose BEACO(D)PP in 39 (6 %) patients, BEACO(D)PP-14 in 159 (26 %) patients, standard BEACO(D)PP in 200 (32 %) patients, IVDG in 25 (4 %) patients, and other regimens in 9 (1.5 %) patients. The second-line treatment was administered in 120 (19 %) out of 622 patients. By the end of August 2018, the number of followed-up patients was 514 (83 %), 108 (17 %) patients had died. The prognostic value of the International Prognostic Score (IPS), PET, and other factors was assessed by means of Cox’s multivariate regression analysis. Pharmacoeconomic analysis of differences between options of first-line therapy was based on Markov model.

Results. In the group of patients with advanced HL stages treated with escalated BEACO(D)PP (the increased-dose regimen and BEACO(D)PP-14) 5- and 10-year overall survival (OS) was 83 % and 74 %, respectively, OS median was not reached. On standard BEACO(D)PP patients with advanced HL stages had OS median of 139 months (11.6 years) and 5- and 10-year OS of 68 % and 54 %, respectively (p = 0,012). In the group of patients with early stages and poor prognosis treated with escalated regimens BEACO(D)PP 5- and 10- year OS was 100 % and 90 %, respectively, in the combined group treated with ABVD and standard BEACO(D)PP it was 83 % and 75 % (p = 0.035). Replacement of procarbazine with dacarbazine in the standard and increased-dose BEACOPP regimens did not affect treatment efficacy. Markov analysis demonstrated the advantages of the escalated regimens for treatment of early stages with poor prognosis and advanced stages in terms of life years gained. Out of 7 IPS factors male sex, age ≥ 45 years, hemoglobin < 105 g/L, and albumin < 40 mg/L significantly impacted OS. Based on these data an adjusted prognostic index was suggested.

Conclusion. The advantage of the escalated strategy of first-line therapy in HL is reflected in survival parameters and is based on pharmacoeconomic evidence. The significance of some laboratory IPS risk factors can be reviewed; most obvious is increasing importance of PET for predicting the need for salvage therapy.

ABSTRACT

Background & Aims. At least one third of patients with diffuse large B-cell lymphoma (DLBCL) are resistant to first-line therapy. R-CHOP chemo-immunotherapy does not yield acceptable results in high-risk patients. Effectiveness of options based either on increasing the dose intensity or on including auto-HSCT into the first-line therapy was not supported by the results of controlled studies. With this background the present study focuses on options, issues and failures of first-line on the basis of long-term follow-up of DLBCL patient population in the Volgograd Region.

Materials & Methods. From 2004 to 2017 the population-based registry of the Hematology Department in the Volgograd Regional Clinical Oncology Dispensary included all 492 primary DLBCL patients: 235 (48 %) men and 257 (52 %) women aged 18 to 88 years. Mean and median age was 59 and 61 years, respectively. CHOP therapy was administered to 206 (42 %) patients, and 223 (45 %) patients received R-CHOP. Other regimens including NHL-BFM-90 and R-DA-EPOCH were used only in 63 (13 %) patients. Second- and third-line therapies were administered to 145 (30 %) and 54 (11 %) patients, respectively. Value of the International Prognostic Index (IPI) and immunomorphologic characteristics was determined by multivariate Cox regression analysis. Pharmacoeconomic aspect of first-line therapy failures was analyzed using Markov model.

Results. Improvement of DLBCL therapy effects with the use of R-CHOP chemo-immunotherapy is particularly obvious in the groups with favorable and intermediate prognosis with 5-year overall survival (OS) of 90 % and 69 %, respectively. R-CHOP results are not considered to be satisfactory in the high-risk group: 5-year OS was 38 %. Pharmacoeconomic analysis proves the advantage of chemo-immunotherapy strategy in comparison with the period before rituximab era in terms of the life years gained (LYG) and the incremental cost-effectiveness ratio (ICER). With respect to immunotherapy effects the most significant immunomorphologic parameter is bcl-2 tumor cell expression. In the group of patients with bcl-2 > 50 % 5-year OS was 61 % with median of 88 months, event-free survival (EFS) was 52 % with median of 62 months. In the group without bcl-2 expression above the threshold 5-year OS and EFS were 88 % and 75 %, respectively, medians were not achieved. With c-myc and bcl-2 coexpression EFS and OS appeared to be even worse: 5-year EFS was 29 % with median of 6 months, and 5-year OS was 31 % with median of 15 months.

Conclusion. The analysis of actual practice demonstrates the need for new options of first-line therapy for DLBCL high-risk patients and also for introducing new discriminating prognostic factors which include the IPI-independent ones.
