Central Nervous System International Prognostic Index Impacts Overall Survival in Diffuse Large B-cell Lymphoma Treated with R-Chop in a third Level Cancer Center from Mexico: A Survey of 642 Patients.

BACKGROUND: Central nervous system international prognosis index (CNS-IPI) is validated in European and the USA cancer databases. However, no validation has been done in Mexican population. OBJECTIVE: The objective of the study was to assess the impact of the CNS-IPI on central nervous system (CNS) relapse and survival in Mexican patients with diffuse large B-cell lymphoma (DLBCL). METHODS: In this retrospective analysis, clinical, biochemical, and histological variables and the CNS-IPI were analyzed. RESULTS: Six hundred and forty-two patients with DBLCL were included in the study. The mean ± SD age was 56.8 ± 14.9 years. Most had an ECOG of 0-1: 75% (n = 484) had absence of B-symptoms and advanced disease (clinical stage: III-IV, n = 433, 67.4%). According to the CNS-IPI, almost one-half were in the low-risk category. According to the CNS-IPI, CNS relapse rate was 1.36% (95% CI: 83.2-92.8), 3.1% (95% CI: 132.4-162.8), and 7.4% (95% CI 61-91) for patients in the low-, intermediate-, and high-risk categories, respectively. The median overall survival in the high-risk group (CNS-IPI) was 22 months, and it has not been achieved after 80 months of follow-up for the other groups. CONCLUSIONS: CNS-IPI was associated with survival; therefore, we propose its use as a prognostic tool for prospective validation.

Relationship between tumor-associated immune infiltrate and p16 staining over clinicopathological features in acral lentiginous melanoma.

PURPOSE: This study aims to evaluate the association between composition of tumor-infiltrating lymphocytes (TIL) and expression of p16 in acral lentiginous melanoma (ALM), and their impact on prognosis. MATERIALS AND METHODS: A cohort of 148 surgical pathology specimens of ALM was studied. TIL were evaluated by immunohistochemical detection of CD3 and CD8, along with CD20, CD4, CD68, and CD163 in a subset of 43 cases. p16 protein expression was also investigated in all the cases. RESULTS: The median age was 66 years, median Breslow thickness was 6.0 mm, grade III TIL was found in 28.4% and lymph nodes were involved in 54.2%. Breslow thickness (p < 0.001), stage I-II (p < 0.001), negative lymph nodes (p < 0.001) and < 10% p16 (p = 0.01) were associated with longer survival. Grade III of TIL was associated with thinner Breslow thickness (p = 0.008) and lower mitosis (p = 0.047). A higher density of CD3 TIL was associated with male gender (p = 0.008), thinner Breslow thickness (p = 0.047), negative lymph node (p = 0.031), early stage (p = 0.046), and p16 nuclear expression of > 10% (p = 0.045). Higher CD8 TIL was associated with > p16 (p = 0.03). Survival analysis found that longer survival had a trend to be associated with high TIL (p = 0.090). Levels of CD3+ and CD8+ cells were correlated with those of CD4+, CD20+, CD68+ and CD163+ immune cells. CONCLUSIONS: Higher levels of TIL tend to be associated with better overall survival in ALM. Loss of expression of p16 is associated with lower levels of CD3+ and CD8+ TIL, indicating a probable relationship between p16 and TIL immune response in ALM .

Factores asociados al pronóstico y supervivencia en pacientes adultos hospitalizados con diagnóstico de leucemia mieloide aguda del hospital nacional dos de mayo período 2014 a 2016 / Factors Associated With Prognosis And Survival In Hospitalized Adult Patients Diagnosed With Acute Myeloid Leukemia At The Hospital Nacional Dos De Mayo Period 2014 To 2016

Introduccion: La supervivencia en pacientes con diagnóstico de Leucemia Mieloide Aguda (LMA) se puede ver afectada por diversos factores clínicos, citogenéticos e inmunofenotípicos. Objetivo: Determinar las características del tamizaje para cáncer CCU en 08 establecimientos de salud (EESS) de Lima Metropolitana sedes del Internado Médico de la FAMURP en el 2017. Métodos: Se realizó un estudio observacional, transversal, retrospectivo y analítico, basado en la revisión de historias clínicas de todos los pacientes adultos con diagnóstico de Leucemia Mieloide Aguda, diagnosticados en Abril del 2014 a diciembre de 2016 y se realizó un seguimiento para determinar su desenlace final a 2 años asociándolo a la presencia de factores condiciones de mortalidad. La muestra final fue de 39 pacientes. Resultados: De los 39 pacientes 16 (41%) fueron mayores de 60 años, 23 (59%) fueron menores de 60 años, 13 de los pacientes (33%) presentaron una cifra de Leucocitos mayor a 50 000 al diagnóstico y 26 (77%) presentaron una cifra menor a 50 000. 33 pacientes presentaron una Leucemia de Novo (84%) y 6 (16%) presentaron una Leucemia secundaria a un Síndrome Mielo Displásico o algún antecedente de quimioterapia previa. No se obtuvo datos de todos los pacientes según clasificación Franco Americano Británica (FAB), Inmunofenotipo y Cariotipo. La supervivencia se evaluó en 3 tiempos, a los 6 meses, al año y a los 2 años desde la fecha del diagnóstico, teniendo que a los 6 meses la sobrevida global de los 39 pacientes había sido el 69 % (25), al año 49% (18) y a los 2 años se mantuvo en el mismo rango. La supervivencia al año y 2 años del diagnóstico se obtuvo el mismo Odds Ratio (OR) de 4.5 para la variable Leucocitos al diagnóstico mayor a 50 000 (IC 95%: 1.008 ­ 20.507), considerándola como un factor de riesgo para mortalidad. En el análisis de supervivencia de la misma variable mencionada con la supervivencia al año y dos años que la supervivencia fue significativamente menor en el grupo de pacientes con leucocitos al diagnóstico mayor a 50 000. Conclusión: En nuestra población de estudio se encontró significancia estadística al momento de evaluar la variable Leucocitos al diagnóstico mayor a 50 000 encontrándola como factor asociado a la mortalidad a 2 años, con una supervivencia significativamente mayor que el grupo de pacientes con Leucocitos al diagnóstico menor a 50 000.

Introduction: Survival in patients diagnosed with acute myeloid leukemia (AML) may be affected by various clinical, cytogenetic and immunophenotypic factors. Methods: An observational, transversal, retrospective and analytical study was conducted, based on the review of clinical histories of all adult patients with diagnosis of acute myeloid leukemia diagnosed in April 2014 to December 2016, a follow-up was made to determine their final outcome at 2 years. We calculated the OR and performed survival curves of each prognosis variable independent associated with survival in 3 times: 6 months, 1 year and 2 years. Results: Of the 39 patients 16 (41%) were older than 60 years, 23 (59%) were less than 60 years, 13 of the patients (33%) showed a number of leukocytes greater than 50 000 to the diagnosis and 26 (77%) showed a number less than 50 000. 33 patients presented a De Novo leukemia (84%) and 6 (16%) presented leukemia secondary to a myelo dysplastic syndrome or some antecedent of previous chemotherapy. No complete data were obtained from all patients according to FAB classification, Immunophenotyping and Karyotype. Survival was assessed in 3 times, at 6 months, year and 2 years from the date of diagnosis, overall survival of the 39 patients was 69% (25) at 6 months, and 49% (18) at 1 and 2 years. For the survival of the year and 2 years of the diagnosis we got the same OR of 4.5 for the variable leukocytes to the diagnosis greater than 50 000(IC 95%: 1,008 ­ 20,507), considering it as a risk factor for mortality. In the survival analysis of the same variable mentioned, survival at year and two years was significantly lower for the group of patients with leukocytes at diagnosis greater than 50 000. Conclusion: In our study, statistical significance was found evaluating the variable Leukocytes at diagnosis greater than 50 000, finding it as an associated factor with mortality to 2 years, with a significantly greater survival than the group of patients with leukocytes at diagnosis less than 50 000.

Evaluation of prognostic factors and survival among patients with osteosarcoma attended at a philanthropic hospital in Teresina, Piauí, Brazil.

OBJECTIVE: Make an analysis of the factors that influence their survival and prognosis of patients with osteosarcoma treated at a Charity Hospital in Teresina-PI. METHODS: We analyzed medical records of 32 patients diagnosed with osteosarcoma in the period January 2005 to December 2010. RESULTS: Patients were aged between 6 and 73 years, with 56.2% men and 43.7% women. The prevailing color was black, with 62.5% of cases. With regard to histological subtype, the majority were osteoblastic type (71.8%). The anatomical location of the tumor was prevalent region of the knee (distal femur and proximal tibia). Regarding the size of the tumor, tumors were 43.8% bigger than 15 cm. Degree of necrosis Huvos concentrated primarily among the types I and II, 53.1% and 25% respectively. The overall survival at two and four years was 45.5% and 39% respectively and event- free survival at two and four years was 39.8% and 19.9% respectively. CONCLUSION: We considered the worst prognosis, the presence of metastases at diagnosis and tumors larger than 15 cm. And the criteria of Huvos did not reach statistical significance for the prognosis of patients.
