ABVD Compared With BEACOPP Compared With CEC for the Initial Treatment of Patients With Advanced Hodgkin's Lymphoma: Results From the HD2000 Gruppo Italiano per lo Studio dei Linfomi Trial

PURPOSE To compare doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) versus bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) versus cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxirubicin, vincristine, procarbazine, vinblastine, and bleomycin (COPPEBVCAD; CEC) for advanced Hodgkins lymphoma (HL). PATIENTS AND METHODS Three hundred seven patients with advanced HL (stage IIB, III, and IV) were randomly assigned to receive six courses of ABVD, four escalated plus two standard courses of BEACOPP, or six courses of CEC, plus a limited radiation therapy program. RESULTS After a median follow-up of 41 months, BEACOPP resulted in a superior progression-free survival (PFS), with a significant reduction in risk of progression (hazard ratio [HR] = 0.50) compared with ABVD. No differences between BEACOPP and CEC, or CEC and ABVD were observed. The 5-year PFS was 68% (95% CI, 56% to 78%), 81% (95% CI, 70% to 89%), and 78% (95% CI, 68% to 86%), for ABVD, BEACOPP, and CEC, respectively (BEACOPP v ABVD, P = .038; CEC v ABVD and BEACOPP v CEC, P = not significant [NS]). The 5-year overall survival was 84% (95% CI, 69% to 92%), 92% (95% CI, 84% to 96%), and 91% (95% CI, 81% to 96%) for ABVD, BEACOPP, and CEC, respectively (P = NS). BEACOPP and CEC resulted in higher rates of grade 3-4 neutropenia than ABVD (P = .016); BEACOPP was associated with higher rates of severe infections than ABVD and CEC (P = .003). CONCLUSION As adopted in this study BEACOPP is associated with a significantly improved PFS compared with ABVD, with a predictable higher acute toxicity.

R-CVP versus R-CHOP versus R-FM for the initial treatment of patients with advanced-stage follicular lymphoma: results of the FOLL05 trial conducted by the Fondazione Italiana Linfomi.

PURPOSE Although rituximab (R) is commonly used for patients with advanced follicular lymphoma (FL) requiring treatment, the optimal associated chemotherapy regimen has yet to be clarified. PATIENTS AND METHODS We conducted an open-label, multicenter, randomized trial among adult patients with previously untreated stages II to IV FL to compare efficacy of eight doses of R associated with eight cycles of cyclophosphamide, vincristine, and prednisone (CVP) or six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or six cycles of fludarabine and mitoxantrone (FM). The principal end point of the study was time to treatment failure (TTF). RESULTS There were 534 patients enrolled onto the study. Overall response rates were 88%, 93%, and 91% for R-CVP, R-CHOP, and R-FM, respectively (P=.247). After a median follow-up of 34 months, 3-year TTFs were 46%, 62%, and 59% for the respective treatment groups (R-CHOP v R-CVP, P=.003; R-FM v R-CVP, P=.006; R-FM v R-CHOP, P=.763). Three-year progression-free survival (PFS) rates were 52%, 68%, and 63% (overall P=.011), respectively, and 3-year overall survival was 95% for the whole series. R-FM resulted in higher rates of grade 3 to 4 neutropenia (64%) compared with R-CVP (28%) and R-CHOP (50%; P< .001). Overall, 23 second malignancies were registered during follow-up: four in R-CVP, five in R-CHOP, and 14 in R-FM. CONCLUSION In this study, R-CHOP and R-FM were superior to R-CVP in terms of 3-year TTF and PFS. In addition, R-CHOP had a better risk-benefit ratio compared with R-FM.

Bisphosphonate-associated osteonecrosis of the jaw: A review of 35 cases and an evaluation of its frequency in multiple myeloma patients

Over a period of 28 months, we observed five cases of osteonecrosis of the jaw (ONJ) in cancer patients treated with bisphosphonates (BP) at our institution. This prompted us to undertake a retrospective, multicenter study to analyse the characteristics of patients who exhibited ONJ and to define the frequency of ONJ in multiple myeloma (MM). We identified 35 cases in Gruppo Italiano Studio Linfomi centers during the period 2002 – 05. The median time from cancer diagnosis to the clinical onset of ONJ was 70 months. In these 35 cases of ONJ, 24 appeared 20 – 60 months after starting BP treatment. The time for the onset of ONJ was significantly shorter for patients treated with zoledronic acid alone than for those treated with pamidronate followed by zoledronic acid. The frequency of ONJ in the MM group during the study period was 1.9%, although the nature of the present study may have resulted in an underestimation of ONJ cases. Our analysis strongly suggested an association between the use of BP and the occurrence of ONJ, although we were unable to identify any definite risk factors with a retrospective study. The most frequently ONJ-associated clinical characteristics were chemotherapy treatment, steroid treatment, advanced age, female sex, anemia, parodonthopaties/dental procedures and thalidomide (in the case of MM patients).

Rituximab plus HyperCVAD alternating with high dose cytarabine and methotrexate for the initial treatment of patients with mantle cell lymphoma, a multicentre trial from Gruppo Italiano Studio Linfomi.

This study investigated the clinical activity and toxicity of R‐HCVAD‐AM [rituximab plus HyperCVAD (R‐HCVAD) alternating with high‐dose cytarabine and methotrexate (AM)] in patients with newly diagnosed Mantle Cell Lymphoma (MCL). Patients aged ≤70 years with confirmed MCL received four alternating cycles each of R‐HCVAD and AM. Patients who obtained a partial response proceeded to autologous stem cell transplant. Sixty‐three patients were enrolled and 60 were fully eligible. Median age was 57 years (22–66); 60%, 33% and 7% were classified at low (L)‐, intermediate (I)‐ or high (H)‐risk, respectively, according to the MCL International Prognostic Index (MIPI). Only 22 patients (37%) completed the four cycles and three patients died during therapy. Overall response and complete response rates were 83% and 72% respectively. After a median follow‐up of 46 months (range 1–72) the estimated 5‐year overall survival (OS) and progression‐free survival rates were 73% [95% confidence interval (CI) 59–83%], and 61% (95%CI 45–73%) respectively. MIPI maintained the prognostic value with an estimated 5‐year OS of 89%, 80% and 24% for L, I, and H groups respectively (P < 0·001). This multicentre study confirms that R‐HCVAD‐AM is an active regimen for the initial treatment of patients with MCL, but is associated with significant toxicity.

Introduction of Rituximab in Front-Line and Salvage Therapies Has Improved Outcome of Advanced-Stage Follicular Lymphoma Patients

It is unclear whether new treatment modalities have improved the survival of follicular lymphoma patients. Some data show that there has been no improvement in survival in the last 3 decades of the 20th century, whereas the results of recent retrospective studies suggest that evolving therapy has improved the outcome for follicular lymphoma patients.

Efficacy and safety of bendamustine for the treatment of patients with recurring Hodgkin lymphoma

The management of patients with Hodgkin lymphoma (HL) recurring after stem cell transplantation (SCT) and multiply relapsed disease remains challenging. We report on 41 such patients who received bendamustine hydrochloride, a bifunctional mechlorethamine derivative mechanistically unrelated to traditional alkylators, after a median of four prior chemotherapy lines, including SCT in 85% of cases. Bendamustine was given at doses of 90–120 mg/m2 every 21 or 28 d. At first assessment (2–4 cycles), the overall response rate (ORR) was 78% with 12 (29%) complete (CR) and 20 (49%) partial responses (PR). Upon treatment prolongation to 6–8 courses, 40% of PRs progressed, yielding a final ORR of 58% with 31% of CRs. Eight patients (two CRs, six PRs) were subsequently allotransplanted. Median progression‐free and overall survival exceeded 11 and 21 months respectively; complete responders displayed a median disease‐free survival above 9 months with a relapse rate of only 30%. Outcomes were independent of disease chemosensitivity, previous transplant and bendamustine dose‐intensity. No life‐threatening or unexpected adverse events occurred. Within the limits of a retrospective analysis and schedule heterogeneity, these results appear very encouraging and prompt prospective trials to confirm bendamustine as a valuable option in the palliative setting and in cytoreductive strategies before allotransplantation.

Long-Term Results of the HD2000 Trial Comparing ABVD Versus BEACOPP Versus COPP-EBV-CAD in Untreated Patients With Advanced Hodgkin Lymphoma: A Study by Fondazione Italiana Linfomi

PURPOSE The randomized HD2000 trial compared six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), four escalated plus two standard cycles of BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), and six cycles of COPP-EBV-CAD (cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxorubicin, vincristine, procarbazine, vinblastine, and bleomycin; CEC) in patients with advanced-stage Hodgkin lymphoma. After a median follow-up of 42 months, patients who received BEACOPP were reported to have experienced better progression-free survival (PFS) but not better overall survival (OS) results than those receiving ABVD. We here report a post hoc analysis of this trial after a median follow-up of 10 years. PATIENTS AND METHODS Three hundred seven patients were enrolled, 295 of whom were evaluable. At the time of our analysis, the median follow-up for the entire group was 120 months (range, 4 to 169 months). RESULTS The 10-year PFS results for the ABVD, BEACOPP, and CEC arms were 69%, 75%, and 76%, respectively; corresponding OS results were 85%, 84%, and 86%. Overall, 13 second malignancies were reported: one in the ABVD arm and six each in the BEACOPP and CEC arms. The cumulative risk of developing second malignancies at 10 years was 0.9%, 6.6%, and 6% with ABVD, BEACOPP, and CEC, respectively; the risk with either BEACOPP or CEC was significantly higher than that reported with ABVD (P = .027 and .02, respectively). CONCLUSION With these mature results, we confirm that patients with advanced Hodgkin lymphoma have similar OS results when treated with ABVD, BEACOPP, or CEC. However, with longer follow-up, we were not able to confirm the superiority of BEACOPP over ABVD in terms of PFS, mainly because of higher mortality rates resulting from second malignancies observed after treatment with BEACOPP and CEC.

Second malignancies after treatment of diffuse large B-cell non-Hodgkin's lymphoma: a GISL cohort study

Improved treatment has increased the life expectancy of patients with non-Hodgkin’s lymphoma, but the risk of second cancer in patients treated for diffuse large B-cell lymphoma is unclear. This Italian study shows that only young patients have an increased incidence ratio of second malignancies, while the incidence ratio in patients aged over 59 years matched that in the Italian general population. Background Improved treatment has increased the life expectancy of patients with non-Hodgkin’s lymphoma, but few studies have addressed the issue of second cancer in patients treated for diffuse large B-cell lymphoma. The aims of this study were to determine the incidence and time free of second cancers in this subset of patients. Design and Methods We evaluated a cohort of 1280 patients with diffuse large B-cell lymphoma who were first treated between 1988 and 2003. We utilized the central database of the Gruppo Italiano Studio Linfomi, which includes data on demographics, clinical characteristics, laboratory parameters, treatment and follow-up of all patients with non-Hodgkin’s lymphoma enrolled in clinical trials. Results After a median follow-up of 51 months, 48 patients had developed a second cancer: 13 hematologic malignancies and 35 solid tumors. The overall standardized incidence ratio in our cohort (with a median age of 58 years) matched that of the general Italian population. The incidence ratio of second tumors was age related, and the age groups 20–39 and 40–59 years showed an increased risk. Overall, the cumulative incidence of second cancer was 8.2% at 15 years. A multivariate analysis showed that older age at the time of diagnosis of lymphoma had a negative influence on the time free of second tumors. Conclusions In our cohort, only young patients showed an increased incidence ratio of second malignancies, while the incidence ratio in patients aged over 59 years matched the incidence in the Italian general population. Demographics, baseline characteristics, laboratory parameters and treatment modalities did not have any significant impact on the incidence ratio of a second cancer.

The role of high-dose therapy and autologous stem cell transplantation in patients with primary refractory Hodgkin's lymphoma: a report from the Gruppo Italiano per lo Studio dei Linfomi (GISL).

GISL recently conducted an exhaustive survey of 1078 patients with Hodgkins Lymphoma (HL) enrolled between 1988 and 2002 in different prospective trials. Treatment failure was observed in 82 out of 1078 patients; of these 82 patients with refractory HL, complete information was available for 72, who form the evaluable population of the present study. After the initial therapy failure, 51 patients were treated with conventional salvage chemotherapy (CC) (n=24) or high-dose chemotherapy (HDC) (n=27); 4-year overall survival (OS) was 81% in the HDC group versus 38% in the CC group (P=0.019). The remaining 21 patients had rapidly progressive disease and died. After a median follow-up of 2.8 years, the projected OS for all 72 patients is 58 and 49% at 3 and 5 years, respectively. Age <45 years, the absence of systemic symptoms and a PS <1 predicted a significantly longer OS. Interestingly, the majority of patients with two or three negative prognostic factors did not receive potentially curative therapy. In conclusion, HDC seems to be a reasonable option for selected patients with refractory HL, although the majority of them did not receive a transplant. Finally, patients with a high-risk score had little chance of receiving potentially curative treatment.

The chronic lymphocytic leukemia international prognostic index predicts time to first treatment in early CLL: Independent validation in a prospective cohort of early stage patients

The chronic lymphocytic leukemia International Prognostic Index (CLL‐IPI) combines 5 parameters (age, clinical stage, TP53 status [normal vs. del(17p) and/or TP53 mutation], IGHV mutational status, serum β2‐microglobulin) to predict survival and time‐to‐first‐treatment (TTFT) in CLL patients. We performed an observational study in 337 prospectively collected, Binet stage A patients to validate the ability of the CLL‐IPI to predict TTFT in an independent cohort of early stage CLL patients. The CLL‐IPI score stratified Binet stage A patients into three subgroups with different outcome. Since the CLL‐IPI was originally developed to predict survival, we next investigated the optimal cut‐off score to predict TTFT in Binet stage A patients. Recursive partitioning analysis identified three subsets with scores of 0 (n = 139), 1 (n = 90), and ≥ 2(n = 108). The probability of remaining free from therapy 5 years after diagnosis was 85%, 67% and 46% in these three categories (P < 0.0001.; C‐statistic:c = 0.72; 95% CI:0.58‐0.81). This optimized CLL‐IPI scoring for TTFT was subsequently validated in an independent cohort of Binet A patients from the Mayo Clinic (n = 525). The ability of either original or optimized CLL‐IPI to predict TTFT was equivalent to other prognostic models specifically designed for this endpoint (2011 MDACC score and O‐CLL1 score). Although originally developed to predict suvival, the CLL‐IPI is useful for predicting TTFT in early stage CLL patients. Am. J. Hematol. 91:1090–1095, 2016.
