TL;DR: It is concluded that CD38 expression and secondary 17p deletion are important poor prognostic indicators, especially in Binet stage A CLL, and should be considered as independent prognostic factors with regard to EFS and TFI.
Abstract: CD38 expression and chromosomal abnormalities are novel prognostic factors in chronic lymphocytic leukaemia (CLL). However, their value remains undetermined. CD38 was evaluated in 123 patients and chromosomal aberrations in 111 cases with fluorescence in situ hybridization (FISH). CD38 expression was found in 27% of the cases. In addition, seven out of 32 CD38- patients became CD38+ during evolution of the disease. Chromosomal abnormalities included isolated 13q deletion (40%), 12q trisomy (14%), 11q deletion (without 17p deletion) (14%) and 17p deletion (7%). CD38 expression was significantly associated with Binet stages B and C, atypical morphology and 11q deletion. On univariate analysis of survival estimates, advanced Binet stages, CD38+ phenotype, atypical morphology and 11q or 17p deletions were associated with shorter event-free survival (EFS), treatment-free interval (TFI) and overall survival (OS). Multivariate analysis identified both Binet stages and CD38 as independent prognostic factors with regard to EFS and TFI. However, CD38 appeared as an independent factor for OS when restricted to Binet stage A. Chromosomal aberrations were re-evaluated during evolution in 31 cases. The 17p deletion was the most frequent new chromosomal abnormality (35%) and significantly associated with death (64%). In conclusion, CD38 expression and secondary 17p deletion are important poor prognostic indicators, especially in Binet stage A CLL.

TL;DR: Thalidomide is an effective treatment for patients with advanced myeloma, in particular, who have no poor-risk features, and the poor results achieved by the other patients emphasize the need for prospective protocols using thalidomides in combination, especially with dexamethasone.
Abstract: BACKGROUND To evaluate treatment by thalidomide and identify predictive factors of survival, event free survival and response among patients with advanced multiple myeloma treated with thalidomide as single agent therapy. PATIENTS AND TREATMENT Patients with advanced multiple myeloma (n=83) were treated with an oral dose of thalidomide (median 400 mg/day). At start of treatment, all patients had active disease and 58 (69%) had received at least one autologous transplantation. RESULTS With a median follow-up of 338 days (range, 247-629 days), 52 patients are alive, whereas 31 died between 8 and 150 days after the first administration of thalidomide. The response to thalidomide was considered as major in 11 patients (13%), partial in 29 patients (35%) and minor in 15 patients (18%), giving a total response rate of 66% (54 out of 83 patients). Thirteen patients had stable disease and 15 patients progressed. In multivariable analysis, age greater than 60 years, short interval between diagnosis and onset of thalidomide, requirement for red blood cell transfusion, IgA isotype, platelets' count or =34.4 g of thalidomide in the first 90 days of treatment had a better outcome than those who received <34.4 g. However, the mean received daily dose of thalidomide in the first 90 days has not been found to influence survival, event free survival or response. Short-term side effects of thalidomide were generally moderate. CONCLUSION Thalidomide is an effective treatment for patients with advanced myeloma, in particular, who have no poor-risk features. The poor results achieved by the other patients emphasize the need for prospective protocols using thalidomide in combination, especially with dexamethasone. In addition, further studies are needed to determine the optimal thalidomide dose and duration.
