Objectives: To evaluate the therapeutic response to treatment with transcriptional therapy that combines hydralazine / valproate(Transkrip) in cancer patients with cutaneous T-cell lymphoma Determine toxicity, duration of response and time to progression of epigenetic therapy with hydralazine / valproate in patients with T-cell lymphomas Material and methods an open-label, phase II, prospective and longitudinal in the National Cancer Institute of Mexico was carried out, recruiting patients diagnosed with Cutaneous T based on WHO classification 2008, newly diagnosed untreated, demographic data were analyzed and vital and somatometry signs, assessment of efficacy was established according to the therapeutic response in lymphomas measured at each visit at the affected sites for each patient, using the m-SWAT system sorted in complete response (CR), partial response (PR ), stable disease (SD) and progression (PE) and is considered response to patients with complete or partial response, these data were collected in the form of case report at baseline in the first consultation, during treatment and at the end the study at each visit to the doctor. Statistical analysis was performed with SPSS version 13.0 software. results 16 patients were selected with diagnosis of cutaneous T-cell lymphoma, one patients discontinued the study at baseline and 4 patients had disease progression during the first months of the study, a total of 10 patients who completed 18 months of study continuing the compassionate use treatment. The median age of patients was 45.8 years analyzed (18-83 years) of which 8 are women (53%) and 7 men (47%) with an ECOG 1 in 93.3% of patients, with an average weight of 72.5 ± 15.99 kg, height 1.6 ± 0.1 m, body mass index 28.3 ± 5.7 kg / m2, 46.7% of overweight patients, systolic blood pressure an average of 116.2 ± 14.3 mmHg and diastolic 75.1 ± 11.04 mmHg with respiratory rate 19.43 ± 1.74 resp / min and 77.8 ± 12.3 cardiac beats / min. Of the 10 patients who completed the study, 100% had complete or partial response itching to 6 month continuing unchanged at month 18, the dream as an adverse event occurred in 33% of patients, this being more frequent, adverse events attributed to the drug were known, expected and mild. From 6 months of treatment, the percentage of partial response and complete response of m-SWAT and pruritus were greater than 90% of patients. conclusions: Hydralazine/Valproate (Transkrip) is a medication that offers patients with cutaneous T-cell lymphoma, both first-line and refractory, a therapeutic alternative with high efficiency and good safety profile.

Extramedullary myeloma (EMM) is defined by the presence of plasma cells outside the bone marrow in a patient with multiple myeloma (MM) (Touzeau & Moreau, 2016). EMM is by itself a rare entity with cases involving central nervous system (CNS) being rarer, it has an estimated incidence of 1-1.8% of all MM cases (Majd et al, 2015). Its presentation in comparison to classical MM has an adverse prognosis including a shorter progression free survival (PFS) (Gozzetti et al, 2015) and overall survival (OS) with a mean life expectancy of 1.5-6 months (Majd et al, 2015). Currently there are not international treatment guidelines for this disease. The aim of this report is to illustrate our experience at a single institution in Mexico, presenting five cases of CNS-EMM treated with proteasome inhibitor (carfilzomib) in combination with thalidomide, dexamethasone plus radiotherapy. The patient's characteristics and the treatment regimen are shown in table 1 and 2. Within three months, following the criteria to the international multiple myeloma working group (IMMWG), all five patients accomplished a positive response (one partial response [PR] four very good partial responses [VGPR]), at sixth months two patients improved their response from previously PR to a VGPR and from VGPR to complete response (CR), one sustained its VGPR and after this period of time two patients had progressive disease (PD) and died due to infectious complications. After the tenth month a third patient also died of infectious complications. By the end of this report two patients still alive, one is being evaluated for autologous stem cell transplantation (ASCT) and the other one wasn't eligible according to European Group for Blood and Marrow Transplantation (EBMT) risk score and will continue treatment without ASCT. Previously reported cases in the literature with old chemotherapy regimens shown to have median survival of 1.5 months (Petersen et al 1999), nowadays the recommended therapy is based on triplet induction therapy followed by high-dose melphalan/ASCT, a triplet consolidation therapy and maintenance treatment with lenalidomide (Touzeau & Moreau, 2016); so far there is no evidence of proteasome inhibitors penetrating the blood brain barrier (Nooka et al, 2013) and this might be the reason why the literature strongly recommends the use of lenalidomide as this one does penetrate into the CSF after oral administration (Muscal et al, 2012), we did not use lenalidomide due to the high monetary cost of the treatment but instead we use thalidomide in combination with carfilzomib and dexamethasone with improved OS in three of our five patients (VGPR + CR). Despite the small number of patients presented in this report and the lack of cytogenetics or FISH information, we think this might be a good therapeutic approached in patients with CNS-EMM, especially in those scenarios with not accessible resources or absence of clinical trials. Further studies evaluating the addition of monoclonal antibodies (daratumumab, elotuzumab) need to be done in order to improve the OS and PFS in this group of patients.
