RESUMO

Gemcitabine (GEM) is currently a standard chemotherapeutic agent for metastatic urothelial carcinoma (mUC). Fever isknown to be an adverse effect of GEM ; however, itsincidence, etiology and clinical significance have not been evaluated. The objective of this study was to elucidate the characteristics and clinical significance of fever associated with GEM in patients with mUC receiving GEM plus cisplatin (GC) chemotherapy. Between 2005 and 2014, 184 patientswith mUC who received first-line GC therapy at 10 institutions were enrolled. GEM-associated fever (GEMAF) was defined as a body temperature ≥37.5ºC within 96 hours after administration of GEM with no evidence of specific conditions causing fever including infection. Clinical parametersbefore GC therapy were evaluated to determine predictorsof GEMAF. Furthermore, the impact of GEMAF on clinical outcomeswasals o evaluated. The median age was70 years and median follow-up was14.2 months. GEMAF wasobs erved in 44 patients (23.9%). In multivariate analysis, elevated C-reactive protein (CRP) before chemotherapy was an independent predictive factor for GEMAF (oddsratio 2.450, p=0.041). There was a significant difference in progression-free survival (median 6.7 vs 8.0 months, p=0.031) and cancer-specific survival (median 12.0 vs 15.8 months, p=0.045) between patients with and without GEMAF. Results of this study suggest that GEMAF is a common adverse event of GC therapy for mUC and can be a poor prognostic factor. GEMAF may be associated with systemic inflammatory response induced by the tumor in patients with mUC.

RESUMO

The transferability and clinical value of genetic risk scores (GRSs) across populations remain limited due to an imbalance in genetic studies across ancestrally diverse populations. Here we conducted a multi-ancestry genome-wide association study of 156,319 prostate cancer cases and 788,443 controls of European, African, Asian and Hispanic men, reflecting a 57% increase in the number of non-European cases over previous prostate cancer genome-wide association studies. We identified 187 novel risk variants for prostate cancer, increasing the total number of risk variants to 451. An externally replicated multi-ancestry GRS was associated with risk that ranged from 1.8 (per standard deviation) in African ancestry men to 2.2 in European ancestry men. The GRS was associated with a greater risk of aggressive versus non-aggressive disease in men of African ancestry (P = 0.03). Our study presents novel prostate cancer susceptibility loci and a GRS with effective risk stratification across ancestry groups.

RESUMO

Prostate cancer is a highly heritable disease with large disparities in incidence rates across ancestry populations. We conducted a multiancestry meta-analysis of prostate cancer genome-wide association studies (107,247 cases and 127,006 controls) and identified 86 new genetic risk variants independently associated with prostate cancer risk, bringing the total to 269 known risk variants. The top genetic risk score (GRS) decile was associated with odds ratios that ranged from 5.06 (95% confidence interval (CI), 4.84-5.29) for men of European ancestry to 3.74 (95% CI, 3.36-4.17) for men of African ancestry. Men of African ancestry were estimated to have a mean GRS that was 2.18-times higher (95% CI, 2.14-2.22), and men of East Asian ancestry 0.73-times lower (95% CI, 0.71-0.76), than men of European ancestry. These findings support the role of germline variation contributing to population differences in prostate cancer risk, with the GRS offering an approach for personalized risk prediction.

RESUMO

OBJECTIVE: We investigated the relationship between the right cardiac system and increased pulmonary artery systolic pressure (PASP) in the elderly. PATIENTS AND METHODS: Echocardiography stable state data were available for 163 of 200 consecutive autopsied patients. Of these, PASP could be estimated by extrapolation from the maximum pressure gradient in tricuspid valve regurgitation from echocardiograms in 73 cases; however, 22 cases with secondary changes attributable to left cardiac insufficiency had to be excluded. We studied the remaining 51 patients in detail (16 men, 35 women, age 68-103 years; mean, 87.7 +/- 8.1). We investigated the following: echocardiographic and pathologic variables, age, sex, body mass index, the survival time (from echocardiography to autopsy), and the presence or absence of chronic pulmonary disease. RESULTS: The average PASP was 39.8 +/- 10.3 mmHg, elevated compared with young persons. Linear regression analysis showed a close correlation of PASP with age (r = 0.35, p = 0.011), thickness of the right ventricle (RV) outflow tract wall as an index of RV hypertrophy (r = 0.35, p = 0.013) and the survival time (r = -0.36, p = 0.0083). By multiple regression analysis, PASP was correlated with the thickness of RV outflow tract (p = 0.0037) even after adjustment for other factors including chronic pulmonary disease. CONCLUSIONS: PASP is elevated in the elderly and it is correlated with the thickness of the RV outflow tract wall as an index of RV hypertrophy.

RESUMO

An 82-year-old woman was admitted with fever and anorexia. Aggravated pancytopenia and liver dysfunction suggested the presence of disseminated intravascular coagulation. The serum ferritin level increased to 9,100 ng/ml. Bone marrow aspiration showed an increase of histiocytes with phagocytosis and a diagnosis of hemophagocytic syndrome was made. Symptomatic therapy was performed because of her deteriorated general condition. She died of multiple organ failure, 32 days after admission. Autopsy revealed swollen lymph nodes with proliferation of large neoplastic cells containing rich cytoplasm and pleomorphic and multi-segmented large nuclei. The immunophenotype of the neoplastic cells was LCA-, CD3-, CD5-, CD 20-, CD79a-, UCHL1-, MT1-, CD15-, p80-. Neoplastic cells were positive for CD30, mainly in Golgi apparati, and also positive for EBV-encoded small nonpolyadenylated RNAs (EBER). This case was diagnosed as anaplastic large cell lymphoma (ALCL) associated with hemophagocytic syndrome. It was estimated that Epstein-Barr virus had played an important role in the development of ALCL in the present case.
