RESUMO
OBJECTIVES: To evaluate the activity and safety of hydralazine and valproate (Transkrip) in cutaneous T-cell lymphoma (CTCL). METHODS: Previously untreated and progressive/refractory CTCL patients received hydralazine at 83 mg or 182 mg/day for slow and rapid acetylators respectively plus magnesium valproate at a total dose of 30 mg/Kg t.i.d daily in continuous 28-day cycles in this phase II study. The primary objective was overall response rate (ORR) measured by the modified severity weighted assessment tool (m-SWAT), secondary end-points were time to response (TTR), time to progression (TTP), duration of response (DOR), progression-free survival (PFS), overall survival (OS) and safety. RESULTS: Fourteen patients were enrolled (7 untreated and 7 pretreated). ORR was 71% with 50% complete and 21% partial. Two had stable disease and two progressed. At a median follow-up of 36 months (5-52), median TTR was 2 months (1-4); median DOR was 28 months (5-45); median PFS 36 and not reached for OS. There were no differences in median TTR, DOR, and PFS between treated and pretreated patients. Pruritus relieve was complete in 13 out of 14 patients. No grade 3 or 4 toxicities were observed. CONCLUSION: The combination of hydralazine and valproate is safe, very well tolerated and effective in CTCL.

Health-related quality of life (HRQL) has become an important outcome measurement in hematology. Our aim was to validate the quality of life questionnaire (QLQ)-MY20 instrument in patients with multiple myeloma (MM) in Mexico. The Mexican-Spanish versions of the QLQ-C30 and QLQ-MY20 instruments were applied to patients with MM at a cancer referral centre. Reliability and validity tests were performed. Test-retest was carried out in selected patients. Ninety-eight patients with MM were included in this study. Questionnaire compliance rates were high, and the instrument was well accepted; internal consistency tests demonstrated good convergent and divergent validity. Cronbach's α coefficients of seven of nine multi-item scales of the QLQ-C30 and of all three multi-item scales of the QLQ-MY20 instruments were >0.7 (range, 0.36-0.89). The scales of the QLQ-C30 and QLQ-MY20 instruments distinguished among clinically distinct groups of patients; 9 of 15 scales of the QLQ-C30 and all 4 scales of the QLQ-MY20 presented responsiveness after change over time. The Mexican-Spanish version of the QLQ-MY20 questionnaire is reliable and valid for the assessment of HRQL in patients with MM and can be used in clinical trials in the Mexican community.

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine. In the face of poor diagnoses devices in most of the Mexican hospitals, we recommend the present diagnose stratification, and treatment guidelines for non-Hodgkin lymphoma, based on evidence. They include the latest and most innovative therapeutic approaches, as well as specific recommendations for hospitals with limited framework and therapy resources.
