Aim. To list and review the combined treatment options in patients with locally advanced metastatic renal cell carcinoma with inoperable metastases to retroperitoneal lymph nodes based on the results of diagnosis and treatment of two patients. Methods. Patients underwent primary tumor resection with further immunotherapy in first case and further immunoradiotherapy in second case. Results. The results of locally advanced metastatic renal cell carcinoma successful treatment are presented. Patient U., aged 73 years was admitted to the oncology department with Karnofsky performance-status score of 50-60 points. The diagnosis of right kidney cancer was set up in 2008, but the patient has refused surgery. At the end of 2011 after general status worsening she was hospitalized for planned surgery. Upper and medium midline laparotomy was performed using the general anesthesia. Enlarged right kidney in retroperitoneum and a batch of paraaortic and paracaval metastatic lymph nodes 13-15 cm in diameter were found at revision, right kidney was substituted by tumor tissue with areas of normal kidney parenchyma at the upper kidney pole, the tumor diameter was 10 cm. Renal artery and vein were gradually separated out of lymph nodes batch with a lot of technical difficulties and stitched and tied up. The specimen was removed as a whole together with paranephric tissues. Post-surgical treatment was complicated by an endogenous intoxication. Immunotherapy with intramuscular oxodihydroacridinylacetate sodium 500 mg every 48 hours i/m could only be started in a month after the surgery. Nowadays the patient is alive and continuing the treatment with oxodihydroacridinylacetate sodium, that induced the clinical improvement and reduced the size of the rest of the affected lymph nodes. Patient K. aged 50 years was admitted by ambulance with the same diagnosis as the first patient, and was treated using the same principles with an addition of radiotherapy. The overall patient’s condition improved after the treatment, there was a reduction of low back pain intensity and reduction of paraaortic and paracaval metastatic lymph nodes aggregate on palpation. Conclusion. Primary tumor resection in presence of inoperable metastatic retroperitoneal lymph nodes with further immunotherapy and radiotherapy can lead to clinical improvement and increase of the patient’s life duration.
