FIELD: surgery; oncology.
SUBSTANCE: invention can be used for interstitial marking of soft tissue tumors. The interstitial marker for tumor imaging includes a radiopaque element made in the form of non-reactive sterile chicken egg shell flour, diluted with methylene blue in 70% alcohol, colored blue. The interstitial marker is absolutely safe, atraumatic, non-reactive, inexpensive and as simple as possible to manufacture.
EFFECT: interstitial marker provides a high degree of visualization of non-palpable and palpable soft tissue tumors before and after chemoradiotherapy for radical excision of the tumor with the peritumoral zone.
