Immunofluorescence is a unique immunochemical method that combines the ability to conduct a detailed morphological analysis and use the specificity of the immunological reaction. The advantage of the immunofluorescence method is its high sensitivity and resolution. The immunofluorescence method was used to survey cell films of venous blood filtrate of cancer patients, and with usage of an apparatus for blood micro-screening, the successful extraction of circulating cancer cells was confirmed.
Application of hemofiltercytological analysis shows its ample opportunities in assessment of polychemotherapy completeness and quality through the study of drug pathomorphosis. The objective of the study was development and studying of the clinical relevance of hemofiltercytological venous blood test as completeness and quality control of patients with colorectal cancer adjuvant chemotherapy. 35 of 39 tested cancer patients who underwent radical surgery for colorectal cancer of different localization, including cases of locally advanced stage had cancer cells in peripheral blood. Thus, the percentage of patients who had atypical cells in venous blood in postoperative period was 89.7. Adjuvant chemotherapy was offered to all 35 patients with diagnosed carcinemia and after their consent it was held in modes FOLFOX-4 and XELOX. Evaluation of anticancer drugs therapeutic action is traditionally carried out using the criteria of objective and subjective effects. The criterion of objective effect during chemotherapy of solid tumors is reduction of tumor and metastases and the criterion of subjective one is well-being of a patient. In addition, it is important to notice the highest drug resistance observed at rectum cancer, because there is a predominance of smaller stages I to II of drug pathomorphosis (9 to 7) over greater stages III-IV (7 to 1) among these cancer patients. Consequently, hemofiltercytological blood test provides a real opportunity to assess the effect of polychemotherapy and to solve the problem of chemotherapeutic treatment courses number necessary to stabilize the cancer process.
This article presents the outcomes of our own research of the detection of circulating cells in the peripheral blood of 48 patients with oncological diseases, using hemocytofiltration. The observed circulating cells (21 cases, 43.8%) have been represented by three variants: more often in the form of “bare” atypical nuclei (76.2% cases), also single conserved tumor cells (14.3%) and large shapeless single cells, probably of non-epithelial nature (9.5%). The difficulties of identifying the obtained cells in light microscopy and technical aspects of the usage of immunocytochemical techniques have been discussed.
Hemofiltercytological venous blood tests for patients radically operated on for colon cancer reveals circulating tumor cells (CTCs) in the early postoperative period. Their results serve as an indication for administration of adjuvant polychemotherapy to post-operative patients. The repeated hemofiltrocytological test on intensity of CTCs damages makes it possible to assess the quality and completeness of adjuvant polychemotherapy.Correspondence to: Sabah Dhibi,
The potential of application of patients’ venous blood hemofiltrocytoanalysis has been presented in the article. An innovative device for blood micro-screening enables specialists to withdraw cancer cells from patients’ blood and diagnose during the very first consultation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
