Similarly, the median Ctrough ratios (Ctrough in monkeys/Ctrough in humans) were 0.96 and 1.71, respectively, when Ctrough was normalized by mg/kg dose as compared with 3.10 and 5.50 when Ctrough was normalized by mg/m2 dose for the same unconjugated and conjugated ASOs, respectively. click here Equivalent CL and dose-normalized plasma Ctrough between monkeys and humans suggest similar pharmacokinetic profiles and tissue distribution between the two species on a per kilogram BW basis. In conclusion, human CL and plasma Ctrough (a surrogate of tissue distribution) can be directly predicted (11 or within twofold) from monkeys by BW on a mg/kg dose basis but these parameters can be under- or over-predicted by BSA on a mg/m2 dose basis. These results provide evidence for single species scaling from monkeys to humans directly and, thus, they can facilitate early human dose prediction in ASO drug development.

The COVID-19 pandemic is a colossal challenge for global health; nonetheless, specific subgroups face considerably higher risks for infection and mortality. Among patients with malignant diseases, those with hematologic neoplasms are at a higher risk for poor outcomes. The objective of this study was to register treatment modifications associated with the COVID-19 pandemic and their short-term consequences in Latin America.

Multicenter, prospective, observational, cohort study including patients older than 14 years from 14 centers in four countries (Mexico, Peru, Guatemala, and Panama) who had a confirmed diagnosis of acute leukemia, and who were undergoing active treatment since the first COVID-19 case in each country until the cutoff on July 15, 2020.

We recruited 635 patients. Treatment modifications because of the COVID-19 pandemic were reported in 40.8% of cases. The main reason for such modifications was logistic issues (55.0%) and the most frequent modification was chemotherapy delay (42.0%). A total of 13.1% patients developed COVID-19 disease, with a mortality of 37.7%. Several factors were identified as independently associated with mortality, including a diagnosis of acute myeloid leukemia (odds ratio 2.38 [95% CI, 1.47 to 3.84];

< .001), while the use of telemedicine was identified as a protective factor (odds ratio 0.36 [95% CI, 0.18 to 0.82];

= .014).

These results highlight the collateral damage of COVID-19 in oncology patients.

The incidence of symptomatic brain metastasis at diagnosis in non-small-cell lung cancer (NSCLC) is 5%-10%, and up to 40% develop during the disease course. There is a paucity of data supporting the role of brain imaging at diagnosis in asymptomatic cases particularly from resource-constraint settings. Here, we present our experience of mandatory baseline brain imaging with contrast-enhanced computed tomography (CECT) scans of all patients with NSCLC.

This was a prospective observation study of patients with NSCLC with mandatory baseline brain CECT and a CNS examination. All histology proven patients with NSCLC diagnosed between January 2018 and October 2019 were included irrespective of stage.

A total of 496 patients were enrolled. The median age was 57 years (range, 23-84) with majority being males (75%) and smokers (66%). The prevalence of epidermal growth factor receptor mutations and anaplastic lymphoma kinase fusions was 33.4% and 12%, respectively. Brain imaging leads to upstaging in 7% cases. Th baseline brain imaging with CECT. NLR and molecular graded prognostic assessment are significant predictors of survival in patients with brain metastasis.

Preoperative chemoradiotherapy according to the chemoradiotherapy for esophageal cancer followed by surgery study (CROSS) has become a standard of care for patients with locally advanced resectable esophageal or junctional cancer. We aimed to assess long-term outcome of this regimen.

From 2004 through 2008, we randomly assigned 366 patients to either five weekly cycles of carboplatin and paclitaxel with concurrent radiotherapy (41.4 Gy in 23 fractions, 5 days per week) followed by surgery, or surgery alone. Follow-up data were collected through 2018. Cox regression analyses were performed to compare overall survival, cause-specific survival, and risks of locoregional and distant relapse. The effect of neoadjuvant chemoradiotherapy beyond 5 years of follow-up was tested with time-dependent Cox regression and landmark analyses.

The median follow-up was 147 months (interquartile range, 134-157). Patients receiving neoadjuvant chemoradiotherapy had better overall survival (hazard ratio [HR], 0.70; 95% CI, 0ble esophageal or junctional cancer who receive preoperative chemoradiotherapy according to CROSS persists for at least 10 years.

Breast cancer civil society organizations have emerged in Eastern Europe and Central Asia to raise awareness about cancer as a survivable disease and provide patient support. We explored the experiences and priorities of these organizations with the goal of making recommendations to advance cancer advocacy and improve cancer care.

We conducted in-depth interviews and focus group discussions with representatives of civil society organizations attending the 7th Women's Empowerment Cancer Advocacy Network Summit in Romania in 2015. Interviews were audiorecorded, transcribed, coded, and analyzed for key themes. Findings were discussed at the 8th Women's Empowerment Cancer Advocacy Network Summit in Ukraine in 2017 to ensure accuracy.

We conducted nine in-depth interviews and three focus group discussions with a total of 36 participants. Survivor- and oncologist-led organizations played an important role in filling existing gaps in public health care systems through awareness raising, patient support, and ad, and local governments.

Our findings highlight the value of providing opportunities for advocates to connect and share experiences. To advance cancer advocacy and improve cancer care, the following needs were identified dissemination of resource-adapted information for improving outcomes; needs assessments; improved program-monitoring practices; and fostering and promotion of collaboration between advocates, medical professionals, and local governments.
