Problem The selective suppression phenomenon of the cytotoxic immune response may be brought about by an increase in sRCAS1 serum concentration during the progression of cancer. Method of study We studied sRCAS1 serum concentration levels in patients with adenocarcinomas and squamous cell carcinomas. The healthy control consisted of patients who were in the mid‐proliferative or mid‐secretory phases of their cycles. Results Statistically, significantly higher sRCAS1 blood serum concentration levels were found in patients experiencing a recurrence of cancer in comparison to those patients who had undergone radical surgical treatment. For patients in the early stages of cancer, sRCAS1 blood serum concentration levels were statistically, significantly higher than those found in patients who were in the proliferative cycle phase and who were comparable to the levels found in patients in the secretory cycle phase. Conclusion The blood serum concentration level of RCAS1 seems to determine the level of immune system activity restriction that accompanies all three processes—decidualization, cancer development, and cancer relapse.
