Predicting Concerns of Cytoreductive Nephrectomy in mRCC
Patients with increased intraoperative blood loss and those treated at lower-volume surgical amenities had a increased threat of high-grade considerations after undergoing cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC), consistent with an prognosis of registry records.
Greater intraoperative blood loss became once also associated with low-grade postoperative considerations. Intraoperative considerations were more most likely in patients who had concurrent thrombectomy and surgical arrangement on adjacent organs.
Eduard Roussel, MD, of University Hospitals Leuven (Belgium) and colleagues reported these findings in European Urology Oncology.
The authors common that the role of CN in mRCC is controversial. With findings published in the Unique England Journal of Medication, the CARMENA trial “shifted treatment paradigms” faraway from surgical arrangement by suggesting that sunitinib by myself is noninferior to sunitinib after CN.
“Nonetheless, there is a general consensus that definite selected subgroups of patients with low-volume, single-plight metastases and few negative IMDC [International Metastatic Renal Cell Carcinoma Database Consortium] criteria would restful non-public the advantage of the persisted expend of upfront CN,” the authors wrote.
They suggested clinicians to weigh the dangers and advantages of CN, in particular on memoir of “postoperative morbidity might perhaps perhaps preclude or extend the expend of subsequent systemic therapies.” Alternatively, the threat/serve calculation for CN has been anxious on memoir of previous investigations non-public tended to heart of attention simplest on survival outcomes, so there isn’t significant records on morbidity, the authors wrote.
Patient Characteristics and Concerns
To match morbidity associated with CN, Dr. Roussel and colleagues reviewed records from the Registry of Metastatic RCC (REMARCC). The workers analyzed the medical records of 736 patients who underwent nephrectomy for mRCC in the midst of 1980-2019.
The patients’ median age became once 63 years (differ, 55-70 years), and about three-quarters were males. The majority had sure cell carcinoma, and the lungs were the most general plight of metastases.
Greater than 97% of procedures were entire nephrectomies, and the relaxation were partial. The median estimated blood loss became once 400 mL, and the median apply-up became once 16.5 months.
There were 69 patients who had intraoperative considerations, most repeatedly bleeding (n = 25), spleen laceration (n = 13), and vascular pains (n = 11).
There were 217 patients who had postoperative considerations, including 45 patients with high-grade considerations (grade 3-5) and 10 who died.
Basically the most in vogue postoperative considerations were vascular/lymphatic in nature. These came about in 67 patients and included 10 lymphoceles.
“[G]iven the moderately high rate of postoperative lymphoceles, which might perhaps perhaps be attributable to the performance of lymph node dissections and the shortage of proven oncological survival serve thereof, surgeons might perhaps perhaps rethink the performance of lymphadenectomy in the midst of CN,” the investigators wrote.
Other general postoperative considerations included infectious and cardiopulmonary points, which came about in 42 and 39 patients, respectively.
Predictors of Concerns
Thrombectomy and adjacent organ elimination were valuable predictors of intraoperative considerations on multivariable prognosis. The percentages ratios were 1.38 (P = .009) for thrombectomy and a pair of.71 (P = .004) for adjacent organ elimination.
Estimated blood loss became once a valuable predictor of low- and high-grade postoperative considerations. The OR for prime-grade considerations per 200 mL of blood lost became once 1.06 (P = .007), and the OR for low-grade considerations per 200 mL blood lost became once 1.09 (P = .001).
There became once a solid inverse correlation with CN case load at every heart and high-grade postoperative considerations, which highlights “the affect of centralization of care on postoperative outcomes in advanced surgical scenarios,” the investigators wrote. The OR per 25 conditions became once 0.88 (P = .04).
Results were largely the identical when the prognosis became once runt to the 560 topics treated since 2006, in the centered treatment abilities, except that adjacent organ elimination as a predictor of intraoperative considerations did no longer pretty reach statistical significance (P = .06).
The presurgery threat factors identified on this take into memoir ought to again with presurgical counseling, mentioned Zachery Reichert, MD, PhD, a genitourinary medical oncologist and assistant professor at the University of Michigan, Ann Arbor, who became once no longer all in favour of this take into memoir.
“This is in particular crucial for patients who require thrombectomy or adjacent organ elimination or secure no longer non-public access to a surgeon with high cytoreductive nephrectomy caseloads,” he mentioned.
Dr. Reichert reported having no disclosures. There became once no exterior funding for this take into memoir, and the investigators didn’t non-public any disclosures.
