Megjegyzések:Introduction: The authors of this paper assessed the surgicalmanagement and outcome of renal cancers when tumorthrombus extended into the inferior vena cava (IVC).Methods: From 2000 to 2015, 46 radical nephrectomies wereperformed on patients with tumor thrombus in the IVC. Themean age of the patients was 60 ? 11 years. Radical nephrectomyand thrombectomies were performed in a single session.There were 18 level-IV, 23 level-III, and 5 level-II tumorthrombi. The operations were performed using cardiopulmonarybypass in 14 patients, while deep hypothermic cardiacarrest was carried out in 4 cases. Results: The mean sizeof the tumors was 9.4 +- 3.5 cm. Histology showed the tumorstages to be pT3b in 21cases, pT3c in 22, and pT4 in 3 patients.The mean follow-up period of the patients was 3.6 +- 3.0 years.During the follow-up period, local recurrence was observedin 7 patients, while distant metastases occurred in 8 cases.The median time to progression was 37 +- 27 months. The5-year overall survival was 43.7%. Conclusions: Radical nephrectomyand thrombectomy provided reasonable long-term survival for patients with renal cancer and IVC thrombus.However, tumor progression was detected in 41.6%. Thepresence of tumor thrombus had a negative effect on tumorprogression and survival.

Cím:Bilateral renal cancers : oncological and functional outcomes / Csaba Berczi, Ben Thomas, Zsolt Bacso, Tibor Flasko

ISSN:0301-1623
Megjegyzések:PURPOSE:The authors assessed the characteristics of bilateral renal cancers.METHODS:From January 1995 to January 2015, 65 patients underwent surgery for bilateral renal cancers. Thirty-four of the patients had 36 synchronous tumors, while the remaining 29 had metachronous tumors. The mean age of the patients was 60 ? 11 years. There were 22 females and 43 males. In all cases, bilateral partial nephrectomies or unilateral nephrectomy and contralateral nephron-sparing surgery were performed.RESULTS:The mean sizes of the synchronous tumors were 5.0 ? 2.7 and 4.7 ? 3.0 cm at the first and the second operations, respectively. The average diameters of the metachronous carcinomas were 6.6 ? 3.0 and 3.1 ? 1.6 cm at the initial and the second surgeries, respectively. Histologic concordance was 91.1 % in the synchronous and 96.5 % in the metachronous tumors. The mean postoperative creatinine levels increased by 116 %, while the GFR decreased by 44.8 % in synchronous tumors at the second operation. The mean postoperative creatinine levels increased by 42 %, while the GFR decreased by 30.4 % in metachronous carcinomas at the second operation. The mean follow-up time was 4.8 ? 3.7 years. During this period, distant metastases occurred in two patients with synchronous tumors and in six cases with metachronous tumors. Local recurrences were detected in one case of synchronous tumor and in four patients with metachronous carcinomas. The 5-year overall and tumor-specific survivals were 53 and 80 %, respectively.CONCLUSIONS:In patients with bilateral renal carcinomas, the histologic concordance was 93.6 %. The bilateral partial nephrectomies or unilateral nephrectomy and contralateral resection provided acceptable oncological and functional outcomes.

Cím:Long-Term Oncological and Functional Outcomes of Partial Nephrectomy in Solitary Kidneys / Csaba Berczi, Ben Thomas, Zsolt Bacso, Tibor Flasko
Dátum:2016
ISSN:1558-7673
Megjegyzések:BackgroundIn this study we assessed the efficacy of nephron-sparing surgery and the changes in renal function after surgery in patients with solitary kidneys.Patients and MethodsFrom January 2000 to January 2015, 50 patients with solitary kidneys underwent partial nephrectomy for renal cancer. In 34 of the patients the contralateral kidneys had been removed previously because of renal tumor. The mean age of the patients was 62 ? 10 years. There were 15 women and 35 men.ResultsThe average diameter of the tumors was 35.2 ? 19.5 mm. The mean preoperative aspects and dimensions used for an anatomical classification score was 7.6 ? 0.7. The mean renal ischemia time was 13.8 ? 6.5 minutes. The mean preoperative and the early postoperative glomerular filtration rate (GFR) were 62 ? 21 mL/min/1.73 m2 and 44 ? 18 mL/min/1.73 m2 (P = .0001), respectively. The mean GFR values decreased by 29% at 1 and at 3 years, and by 36% at 5 years after surgery. All changes in postoperative GFR levels were significant compared with the preoperative values. The tumor size and the warm ischemia time were risk factors for the long-term renal function. The mean follow-up time was 106 ? 96 months. During this period local recurrence occurred in 1 patient, and distant metastases were diagnosed in 4 cases. The 5-year overall, disease-specific, and recurrence-free survival were 88%, 93%, and 88%, respectively.ConclusionPartial nephrectomy provides a good oncological outcome. However, after nephron-sparing surgery most patients develop chronic renal disease, although hemodialysis treatment is rarely necessary. The tumor size and the warm ischemia time showed a close correlation with the long-term renal function.
