- Objectives: Thalidomide and bortezomib have been frequently used for second-line therapy in patients with myeloma relapsing after or refractory to initial melphalan-based treatment, but no randomized trials have been published comparing these two treatment alternatives. Methods: Thalidomide- and bortezomib-naïve patients with melphalan refractory myeloma were randomly assigned to low-dose thalidomide + dexamethasone (Thal-Dex) or bortezomib + dexamethasone (Bort-Dex). At progression on either therapy, the patients were offered crossover to the alternative drug combination. An estimated 300 patients would be needed for the trial to detect a 50% difference in median PFS between the treatment arms. Results: After inclusion of 131 patients, the trial was prematurely closed because of low accrual. Sixty-seven patients were randomized to Thal-Dex and 64 to Bort-Dex. Progression-free survival was similar (median, 9.0 months for Thal-Dex and 7.2 for Bort-Dex). Response rate was similar (55% for Thal-Dex and 63% for Bort-Dex), but time to response was shorter (P < 0.05) and the VGPR rate higher (P < 0.01) for Bort-Dex. Time-to-other treatment after crossover was similar (median, 13.2 months for Thal-Dex and 11.2 months for Bort-Dex), as was overall survival (22.8 months for Thal-Dex and 19.0 for Bort-Dex). Venous thromboembolism was seen in seven patients and cerebrovascular events in four patients in the Thal-Dex group. Severe neuropathy, reactivation of herpes virus infections, and mental depression were more frequently observed in the Bort-Dex group. In the quality-of-life analysis, no difference was noted for physical function, pain, and global quality of life. Fatigue and sleep disturbances were significantly more prevalent in the Bort-Dex group. Conclusions: Thalidomide (50–100 mg daily) in combination with dexamethasone seems to have an efficacy comparable with that of bortezomib and dexamethasone in melphalan refractory myeloma. However, the statistical strength of the results in this study is limited by the low number of included patients.

- The outcome for multiple myeloma patients has improved since the introduction of bortezomib, thalidomide and lenalidomide. However, studies comparing new and conventional treatment include selected patient groups. We investigated consecutive patients (n = 1638) diagnosed in a defined period and compared survival with a gender- and age-matched cohort Swedish population (n = 9 340 682). Median overall survival for non-high-dose treated patients was 2.8 years. The use of bortezomib, thalidomide or lenalidomide in first line therapy predicted a significantly longer overall survival (median 4.9 years) compared to conventional treatment (2.3 years). Among non-high-dose treated patients receiving at least 2 lines with bortezomib, thalidomide or lenalidomide, 69% and 63% have survived at 3 and 5 years as compared to 48% and 22% with conventional drugs and 88% and 79% in the matched cohort populations, respectively. The median overall survival in high-dose treated patients was 6.9 years. Of these patients, 84% survived at 3 years and 70% at 5 years as compared to 98% and 95% in the matched cohort population. Overall survival in the best non-high-dose treated outcome group is closing the gap with the matched cohort. Upfront use of new drugs is clearly better than waiting until later lines of treatment.

- Background: Patients with certain autoimmune diseases (AID) have an increased risk of developing diffuse large B-cell lymphoma (DLBCL). However, the occurrence of AID in patients with DLBCL as well as the impact of AID on outcome has not been extensively studied. The main purpose of this study was to establish the occurrence of AIDs in a population-based cohort of DLBCL patients and to compare outcomes in patients with or without AID treated with rituximab(R)-CHOP/CHOP-like treatment. We also aimed to analyse gender differences and the potential role of different AIDs on outcome and the frequency of treatment-associated neutropenic fever. Patients and methods: All adult patients treated 2000-2013 with R-CHOP/CHOP-like treatment for DLBCL in four counties of Sweden were included (n = 612). Lymphoma characteristics, outcome and the presence of AID were obtained through medical records.Results: The number of patients with AID was 106 (17.3%). Thyroid disease dominated (n = 33, 31.1%) followed by rheumatoid arthritis (RA) (n = 24, 22.6%). The proportion of AID was significantly higher in females (59/254, 23.2%) vs. in males (47/358, 13.1%) (p = .001). In the whole cohort there was no difference in event free survival (EFS) or overall survival (OS) between patients with or without AID. However, patients with an AID primarily mediated by B-cell responses (thyroid disorders excluded) had a worse OS (p = .037), which seemed to affect only women. The AID group more often had neutropenic fever after first treatment (16.0% vs 8.7%, p = .034) and those with neutropenic fever had a worse OS (p = .026) in Kaplan-Meier analyses. Conclusion: There is a high prevalence of AID among patients with DLBCL. AIDs categorized as primarily B-cell mediated (in this study mainly RA, systemic lupus erythematosus and Sjögren's syndrome) may be associated with inferior OS. AID patients may be more prone to neutropenic fever compared to patients without concomitant AID.

Does the omission of vincristine in patients with diffuse large B cell lymphoma affect treatment outcome?

- The standard treatment for diffuse large B cell lymphoma (DLBCL) is rituximab with CHOP (cyclophosphamide, doxorubicin, vincristine (VCR), and prednisone). Maintaining high dose intensity of cytotoxic treatment has been associated with better outcome but little is known about the role of maintaining VCR. This study aimed to answer whether the omission of vincristine due to neurotoxicity affects patient outcome. A Swedish cohort of patients primarily treated with curative intent for DLBCL or high-grade malignant B cell lymphoma was retrospectively analyzed. In total, 541 patients treated between 2000 and 2013 were included. Omission of VCR was decided in 95 (17.6%) patients and was more often decided during the last three cycles (n = 86, 90.5%). The omission of VCR did not affect disease-free or overall survival neither in the whole cohort nor in elderly patients. On the contrary, the relative dose intensity of doxorubicin was associated with overall survival (p = 0.014). Kidney or adrenal involvement (p = 0.014) as well as bulky disease (p = 0.037) was found to be associated with worse overall survival. According to our results, clinicians can safely decide to omit VCR in case of severe neurotoxicity due to VCR but should be aware of the importance of giving adequate doses of doxorubicin during treatment given the growing body of evidence on the role of dose intensity on survival. Considering the association of bulky disease and kidney/adrenal manifestation of lymphoma on survival, further studies should focus on whether the treatment options for these subgroups need to be individualized.

- Routine follow-up for diffuse large B-cell lymphoma have been shortened to 2 years when event-free survival at 24 months (EFS24) emerged as a new milestone. In the present study, we aimed to determine whether the achievement of this milestone affected overall survival (OS). We compared OS to that of an age- and sex-matched population, analysed other factors governing OS, and reviewed the causes of death. Data were collected from the Swedish Cancer Registry and from individual patient's records. We included 1169 adult patients from five counties between the years 2001 and 2014. The median (range) age was 64·6 (18-91) years, 56·6% were men and the median follow-up was 82·3 months. For early stages, the achievement of EFS12 did not improve OS. More than two-thirds of the patients (n = 837, 71·6%) achieved EFS24, of which 190 (22·7%) died during follow-up. Lymphoma (20%), cardiovascular disease (22·4%) and malignancies (16%) contributed to causes of death. Patients aged <60 years had an OS that matched the standard population. In multivariate analysis, only age >60 years significantly affected OS after EFS24 compared with the standard population. We concluded that follow-up beyond EFS24 should be considered for patients aged >60 years.
