[The efficacy of thalidomide for multiple myeloma: a clinical analysis of 102 Chinese patients].
OBJECTIVE
To analyse the efficacy and safety of thalidomide (Thal) for patients with multiple myeloma (MM).


METHODS
Effectiveness and adverse events of 102 MM patients treated with thalidomide at a median dosage of 200 mg/d. Thirteen cases were treated with Thal alone (group A), and 105 case with Thal in combination with other therapeutic agents (group B) were retrospectively analyzed.


RESULTS
1) The response rate (RR) (CR + PR) was 65.4% for induction therapy in 52 cases and 45.5% for salvage therapy in 66 cases. RR in group B was higher than that in group A (58.1% versus 23.1/%, P= 0.017), and the non-response/progress (NR) rate was lower (15.2% versus 46.2%, P= 0.015). In group B, the NR rate was lower in 50 cases of newly diagnosed MM than in 55 cases of refractory or relapsed MM (6.0% versus 23.6%, P=0.012). In group B, RR between Thal+VAD or M, regimen (72 cases) and Thal + MP regimen (33 cases) was not statistically significant (62.5% versus 48.5%, P >0.05). 2) The median duration of response maintenance was 15.5 (1.0-58.0) months in 21 cases. 3) Among 97 patients with follow-up data, the estimated median duration of OS was 44 months in a median follow-up duration of 20 months and the accumulative time for use of Thal was 8 months. In univariate analysis,the accumulative duration for use of Thal 6 months, hemoglobin > or = 100 g/L and bone marrow megakaryocytes > 20 per smear were associated with longer OS (P = 0.0014, 0.0101, 0.019, respectively). 4) Multivariate analysis suggested that the accumulative time for use of Thal and bone marrow megakaryocytes > 20 were independent good prognostic factors for OS (P = 0.006, 0.036, respectively). 5) The adverse events of Thal were mostly endurable, the rate of thrombus events was lower than that reported in literature.


CONCLUSIONS
Thalidomide alone or combined with chemotherapy is an useful therapy for MM. The accumulative time for use longer than 6 months may improve survival.
