[The successful surgical treatment of hypernephroid cancer in 2 patients with multiple myeloma].

The authors related two cases of multiple myeloma BJX and GX combined with hypernephroid cancer. In both cases, the diagnosis of myeloma was supported by morphological examination of the bone marrow and immunochemical identification of monoclonal immunoglobulin. In female patient C, adenocarcinoma developed in the presence of polycystosis in the left kidney operated before. The diagnosis of hypernephroma was established simultaneously with the diagnosis of multiple myeloma BJX, stage III B. The patient was operated on 15 months after institution of polychemotherapy in the presence of myeloma reduction and recovery of nitrogen secretory renal function. The patient survived for 2.5 years after the operation, retaining work fitness for 2 years. She died from terminal exacerbation of myeloma. On autopsy no cancer metastases were detected. In male patient Ch. with myeloma GX, stage II A, hypernephroid cancer of the right kidney was diagnosed 7 months after the diagnosis of myeloma was established. Radical operation resulted in complete somatic and hematological compensation of the patient. The residual mass of myeloma does not manifest itself clinically after 9 courses of polychemotherapy carried out in the preoperative period. It is only detectable by the laboratory tests. The follow-up of the patient is continued.
