The evaluation of risk factors leading to early deaths in patients with acute promyelocytic leukemia: a retrospective study.

Acute promyelocytic leukemia (APL) differs from other forms of acute myeloid leukemia (AML), including coagulopathy, hemorrhage, disseminated intravascular coagulation (DIC), and treatment success with all-trans retinoic acid (ATRA). Despite ATRA, early deaths (ED) are still common in APL. Here, we evaluated factors associated with ED and applicability of scoring systems used to diagnose DIC. Ninety-one APL patients (55 females, 36 males, and median age 40 years) were included. ED was defined as deaths attributable to any cause between day of diagnosis and following 30th day. DIC was assessed based on DIC scoring system released by the International Society of Thrombosis and Hemostasis (ISTH) and Chinese Diagnostic Scoring System (CDSS). Patients' median follow-up time was 49.2 months, and ED developed in 14 (15.4% of) cases. Patients succumbing to ED had higher levels of the Eastern Cooperative Oncology Group Performance Status (ECOG PS), lactate dehydrogenase (LDH), and ISTH DIC, and lower fibrinogen levels (p <0.05). In multivariate Cox regression analysis, age >55 and ECOG PS ≥2 rates were revealed to be associated with ED. Based on ISTH and CDSS scores, DIC was reported in 47.3 and 58.2% of the patients, respectively. Despite advances in APL, ED is still a major obstacle. Besides the prompt recognition and correction of coagulopathy, those at high ED risk are recommended to be detected rapidly. Implementation of local treatment plans and creating awareness should be achieved in hematological centers. Common utilization of ATRA and arsenic trioxide (ATO) may be beneficial to overcome ED and coagulopathy in APL patients.

The Incidence of Venous Thromboembolism and Impact on Survival in Hodgkin Lymphoma.

BACKGROUND: Thrombosis increase the acute and long-term morbidity and mortality in malignancy patients. We analyzed venous thromboembolism (VTE) in patients with Hodgkin lymphoma, the impact of VTE on survival, predisposing factors for VTE, and predicting value of Khorana and ThroLy score models. PATIENTS AND METHODS: We included 150 adult patients with Hodgkin lymphoma between January 2010 and 2018 at our university hospital. RESULTS: VTE was observed in 31 patients (20.7%). The types of VTE were 18 upper and 3 lower extremity deep vein thrombosis and 10 pulmonary embolism (1 with lower extremity deep vein thrombosis). Twenty-nine patients developed VTE during the treatment with a median time of episode as 5 months. In logistic regression analysis, a body mass index of >32 kg/m2, high fibrinogen levels, initial thrombocytosis and leukocytosis, splenic and extranodal involvement, presence of a central venous line, advanced stage, line of treatment status of thromboprophylaxis, VTE timing, and better Eastern Cooperative Oncology Group performance scores were observed to be related with VTE. Kaplan Meier survival analysis showed a negative impact of VTE on survival. Khorana and ThroLy risk assessment models were found predictive for VTE (P = .000 and P = .003, respectively), although only ThroLy score was associated with the survival. CONCLUSION: Thromboprophylaxis and precautions for VTE in patients with Hodgkin lymphoma according to validated risk assessment models can improve prognosis and quality of life owing to the impact of VTE on survival in the study.

Concepts of Double Hit and Triple Hit Disease in Multiple Myeloma, Entity and Prognostic Significance.

Risk assessment in newly diagnosed multiple myeloma patients (NDMM) is the first and the most crucial determinant of treatment. With the utilization of FISH analysis as a part of routine practice, high risk Multiple Myeloma (MM) is defined as having at least one of the mutations related with poor prognosis including; t(4;14) t(14;16), t(14;20), del 17p, p53 mutation, gain 1q and del 1p. M-Smart MM risk stratification guideline by Mayo Clinic has proposed a concept similar to high grade lymphomas. Having two of the high risk genetic abnormalities were defined as double hit MM and having any three as triple hit MM. Based on these definitions which may bring a much more clinically relatable understanding in MM prognosis, we aimed to assess our database regarding these two concepts and their probable significance in terms of outcome and prognosis. We retrospectively evaluated 159 newly diagnosed multiple myeloma patients and their clinical course. Among these patients; twenty-four patients have one high risk determinant and also seven and two patients were classified as double hit MM and triple hit MM respectively. Overall survival (OS) of the patients with double hit MM was 6 months, 32.0 months for patients with single high risk abnormality and 57.0 months for patients with no high risk abnormality. Univariate analysis showed that Double Hit and Triple Hit MM is a predictive of low OS. Hazard Ratio of patients with one high risk abnormality was 1.42, double-hit MM patients was 5.55, and triple-hit MM patients was 7.3. Despite the development of novel drugs and their effects of prolonging survival, the treatment has not been individualized. Understanding the biology of each patient as a unique process will be the success of the treatment. As it is known that some MM patients harbor high risk genetic abnormalities according to FISH analysis, we can continue the argument that some patients bring an even higher risk and that can be defined as double or triple hit MM.
