International multicenter study comparing COVID-19 in patients with cancer to patients without cancer: Impact of risk factors and treatment modalities on survivorship.

Background: In this international multicenter study, we aimed to determine the independent risk factors associated with increased 30 day mortality and the impact of cancer and novel treatment modalities in a large group of patients with and without cancer with COVID-19 from multiple countries.

Methods: We retrospectively collected de-identified data on a cohort of patients with and without cancer diagnosed with COVID-19 between January and November 2020 from 16 international centers.

Results: We analyzed 3966 COVID-19 confirmed patients, 1115 with cancer and 2851 without cancer patients.

International Multicenter Study Comparing Cancer to Non-Cancer Patients with COVID-19: Impact of Risk Factors and Treatment Modalities on Survivorship.

Background: In this international multicenter study we aimed to determine the independent risk factors associated with increased 30-day mortality and the impact of novel treatment modalities in a large group of cancer and non-cancer patients with COVID-19 from multiple countries.

Methods: We retrospectively collected de-identified data on a cohort of cancer and non-cancer patients diagnosed with COVID-19 between January and November 2020, from 16 international centers.

Results: We analyzed 3966 COVID-19 confirmed patients, 1115 cancer and 2851 non-cancer patients.

The molecular heterogeneity of the precancerous breast affects drug efficacy.

In the therapeutic domain, targeted therapies have been shown to be generally more effective when given to patients with tumors that harbor the targeted aberration. This principle has not been tested in cancer prevention despite evidence that molecular heterogeneity accompanies the multi-step progression to invasive disease. We hypothesized that efficacy of agents targeting the precancerous state varies based on timing of the treatment relative to the underlying molecular changes.

Fully automated preparation of Ga-PSMA-11 at curie level quantity using cyclotron-produced Ga for clinical applications.

Ga-PSMA-11 is currently one of the most investigated PET agents for imaging both recurrent prostate cancer and relevant metastases; however, the production and distribution of Ga-PSMA-11 is limited to a supply of only a few daily doses when using a commercially available Ge/Ga generator. Ge/Ga generators deliver only a modest amount of activity, up to 1850 MBq (50 mCi), when new, but it decreases with time. Additionally, the production of Ga/Ge generators has not been able to meet the increasing demand of Ga radiotracers.
