The increasing popularity of the concept of liquid biopsy, which involves the definition of circulating tumor cells and circulating nucleic acids in the blood can significantly improve long-term results of treatment for gastric cancer due to the high sensitivity of techniques. It needs further study in relation to gastric cancer, the search for universal markers and methods.

Standard methods of diagnostics haven't got a proper sensitivity and specificity concerning assessment of regional nodal involvement in case of rectal cancer. Therefore it is necessary to look for new method of diagnostics, detect risk factors and unfavorable prognosis in relation to lateral lymph node metastasis. At the same time, there should be a differentiated approach to the choice of therapeutic management in rectal cancer. Investigation of variability of blood supply of the rectum could be an additional method of diagnostics in rectal cancer.
