Target heterogeneity in oncology : the best predictor for differential response to radioligand therapy in neuroendocrine tumors and prostate cancer
Tumor or target heterogeneity (TH) implies presence of variable cellular populations having
different genomic characteristics within the same tumor, or in different tumor sites of the same
patient. The challenge is to identify this heterogeneity, as it has emerged as the most common cause
of ‘treatment resistance’, to current therapeutic agents. We have focused our discussion on ‘Prostate
Cancer’ and ‘Neuroendocrine Tumors’, and looked at the established methods for demonstrating
heterogeneity, each with its advantages and drawbacks. Also, the available theranostic radiotracers
targeting PSMA and somatostatin receptors combined with targeted systemic agents, have been
described. Lu-177 labeled PSMA and DOTATATE are the ‘standard of care’ radionuclide therapeutic
tracers for management of progressive treatment-resistant prostate cancer and NET. These approved
therapies have shown reasonable benefit in treatment outcome, with improvement in quality of
life parameters. Various biomarkers and predictors of response to radionuclide therapies targeting
TH which are currently available and those which can be explored have been elaborated in details.
Imaging-based features using artificial intelligence (AI) need to be developed to further predict the
presence of TH. Also, novel theranostic tools binding to newer targets on surface of cancer cell should
be explored to overcome the treatment resistance to current treatment regimens.http://www.mdpi.com/journal/cancerspm2021Nuclear Medicin
Presolar grains from meteorites: Remnants from the early times of the solar system
This review provides an introduction to presolar grains - preserved stardust
from the interstellar molecular cloud from which our solar system formed -
found in primitive meteorites. We describe the search for the presolar
components, the currently known presolar mineral populations, and the chemical
and isotopic characteristics of the grains and dust-forming stars to identify
the grains' most probable stellar sources. Keywords: presolar grains,
interstellar dust, asymptotic giant branch (AGB) stars, novae, supernovae,
nucleosynthesis, isotopic ratios, meteoritesComment: 71 pages, 24 figures, 9 tables. Invited review. to appear in Chemie
