METHOD FOR PREVENTION OF RECURRENT MALIGNANT PELVIC TISSUES OR NON-ORGAN RETROPERITONEAL TUMOURS FOLLOWING SURGICAL MANAGEMENT Russian patent published in 2013 - IPC A61N5/67 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology and may be used for the purpose of prevention of recurrent malignant pelvic tumours or non-organic retroperitoneal tumours following the surgical management. A photosensitiser having high tropism to pelvic and retroperitoneal tumour tissues is administered intravenously. A completely extracted tumour bed is exposed to a photodynamic effect within healthy tissues using a light source of wave length characteristic of the photosensitiser used. It is combined with simulating an exposure field by placing a moistened surgical drape in a surgical wound. The laser exposure is generated by using a macrolens from at least one position. An irradiation energy dose makes 840 J to 1710 J.

EFFECT: method enables improving the effectiveness of photodynamic therapy ensured by using the photosensitisers with high tropism to pelvic and retroperitoneal tumour tissues and a possibility to increase a dose of laser light through generating the exposure field and determining its clear limits.
