Our first Research Topic
Volume I: Computational Methods in Inferring Cancer Tissue-of-Origin and Cancer Molecular Classification (https://fro.ntiers.in/jBPY) has over 11 accepted articles and another 15 currently under review. Based on this success, we are launching a second volume for further submissions.
Inferring cancer tissue-of-origin and molecular classification are two critical problems in personalized cancer therapy. It is known that there are about 5% cancers of unknown primary (CUP) site. These kinds of patients are under empirical chemotherapy, which leads to a very low survival rate. Thus, it is important to infer cancer tissue-of-origin. However, experimental methods usually fail to identify the exact tissue-of-origin even after the death of a patient, which provides a need for computational methods especially in the era of big biomedical data. Based on the finding that gene expressions of metastasis cancer cells are more similar to those of original tissue than metastasis tissue, there have been a few computational methods developed in this area. However, the accuracy of the methods is yet to be improved to assure a clinical usage. In addition to CUP, inferring cancer tissue-of-origin is also important in avoiding misdiagnosis even if the cancer origin is known.
On the other hand, cancer molecular classification has been proven to be useful in optimizing treatment methods. With the accumulation of genetic and prognosis data, it is possible to mining a better molecular classification for most cancer types based on historical data especially when more and more single cell data are available. A better cancer molecular classification and better set of markers are critical for developing more efficient cancer treatment and new drugs. We aim to comprehensively discuss themes covering cancer tissue-of-origin and molecular classification towards personalized cancer therapy. This topic can involve not only many kinds of methods/algorithms or code/tools to infer the origins and molecular classification, but also translational studies for cancer treatment in hospitals.
As in the previous topic, we welcome investigators to contribute Original Research as well as Review articles on methods/algorithms/code/tools and clinical applications. Potential topics include but are not limited to the following:
