Follow-up and outcome of the twelve-year experience in adult patients with acute promyelocytic leukemia.

Acute promyelocytic leukemia is a subtype of acute myeloid leukemia, characterized by the presence of neoplastic promyelocytes, due to the reciprocal balanced translocation between chromosomes 15 and 17. Currently, with the use of agents that act directly on this molecular change, such as all-trans retinoic acid and arsenic trioxide, APL has shifted from a highly mortal to a curable disease. However, some cases are still at high risk of death, especially early death, and acquiring a better understanding of the clinical and biological factors involving APL is needed to correctly identify and treat such cases. The early suspected diagnosis and prompt initiation of the target therapy are important for better response rates. The follow-up and outcomes, using real-life data from 44 consecutive APL patients, were studied between 2001 and 2013. The overall survival rate was 82.7% and early death was 16%. Almost all patient deaths were due to severe bleeding, which was confirmed by multivariate analysis, as the most important prognostic factor leading to death. A better understanding the pathogenesis of the hemorrhagic complications in APL is needed, as well as the risk factors associated with early death in APL patients, as this has become synonymous with overall mortality.

Prognostic Factors, Survival Analyses and the Risk of Second Primary Cancer: A Population-Based Study on Burkitt Lymphoma/Leukemia.

Burkitt lymphoma/leukemia (BL/L) is an aggressive oncohematological disease. This study evaluated the population-based prognosis and survival on BL/L as well as if BL/L behaved as a risk factor for the development of second primary cancers (SPCs) and if other first tumors behaved as risk factors for the occurrence of BL/L as an SPC. A retrospective cohort using the Surveillance, Epidemiology and End Results (SEER) Program (2008-2016) was performed. Kaplan-Meier, time-dependent covariate Cox regression and Poisson regression models were conducted. Overall, 3094 patients were included (median, 45 years; IQR, 22-62). The estimated overall survival was 65.4 months (95% CI, 63.6-67.3). Significantly more deaths occurred for older patients, black race, disease at an advanced stage, patients without chemotherapy/surgery and patients who underwent radiotherapy. Hodgkin lymphomas (nodal) (RR, 7.6 (3.9-15.0; p < 0.001)), Kaposi sarcomas (34.0 (16.8-68.9; p < 0.001)), liver tumors (3.4 (1.2-9.3; p = 0.020)) and trachea, mediastinum and other respiratory cancers (15.8 (2.2-113.9; p = 0.006)) behaved as risk factors for the occurrence of BL/L as an SPC. BL/L was a risk factor for the occurrence of SPCs as acute myeloid leukemias (4.6 (2.1-10.4; p < 0.001)), Hodgkin lymphomas (extranodal) (74.3 (10.0-549.8; p < 0.001)) and Kaposi sarcomas (35.1 (12.1-101.4; p < 0.001)). These results may assist the development of diagnostic and clinical recommendations for BL/L.

Chemotherapy Treatments for Burkitt Lymphoma: Systematic Review of Interventional Studies.

BACKGROUND: Burkitt lymphoma (BL) is an aggressive hematologic cancer. This study synthetized the evidence about the efficacy and safety of chemotherapy treatments used in patients with BL using the World Health Organization classification. MATERIALS AND METHODS: A systematic review of interventional studies was performed. A search was carried out in PubMed, Scopus, and Web of Science, with additional manual and gray literature searches. The methodological quality of articles was assessed with the Newcastle-Ottawa scale. RESULTS: We identified 1358 studies; 9 nonrandomized studies satisfied the eligibility criteria (n = 544 patients). The BL epidemiologic variants were sporadic BL (44.5%), endemic BL (47.2%), and immunodeficiency-associated BL (8.3%). Regarding chemotherapy protocols, 4 groups were identified: based on CODOX-M/IVAC (n = 4), EPOCH (n = 1), BFM (n = 1), and simplified treatment schemes used in African countries (n = 3). Most studies had moderate quality. Empirically and qualitatively, the best options for adults with sporadic BL were 'DA-EPOCH-R' (7-year overall survival [OS], 100%; 95% confidence interval [CI], 82-100), 'HDR + LD into CODOX-M/IVAC' (2-year OS, 84%), and 'RD-CODOX-M/IVAC' (4-year progression-free survival, 92%; 95% CI, 77-100); in pediatric patients, the 'BFM-NHL-90-like' showed promising results (3-year OS, 90%). For immunodeficiency-associated BL, the 'SC-EPOCH-RR' demonstrated a good therapeutic profile (6-year OS, 90%; 95% CI, 60-98). The 'Malawi 2012-2014' (1-year OS, 73%; 95% CI, 61-85) could be the treatment choice in endemic BL (African countries). The main adverse events were hematologic. CONCLUSION: Selecting chemotherapy protocols for BL should be grounded in its epidemiologic variants. Further studies with greater methodological quality are needed to strengthen the evidence.

Impact of leukemia and lymphoma chemotherapy on oral cavity and quality of life.

This study aimed to understand how patients perceive their oral health and the resulting oral manifestations of antineoplastic chemotherapy, as well as to analyze the impact of these alterations on oral health-related quality of life. A total of 80 patients undergoing treatment participated in this study. A questionnaire was applied using the Oral Health Impact Profile (OHIP-14) index and open interviews. Items with the highest impact prevalence included "worsened taste of food sensation" (35.00%), "discomfort in eating food" (20.00%), and "feeling stressed" (17.50%). The outpatients showed the highest prevalence scores, whereas the inpatients presented higher quality of life impact severity. The ways in which the patients perceived how their oral alteration affected their quality of life were distinct and subjective. It is important that dentists act together with a multiprofessional team developing strategies to alleviate the impact of the disease and chemotherapy on oral cavity and patients' quality of life.
