Abstract

Background

The objective of this study was to modify the adrenal gland-sparing strategy based on retroperitoneal laparoscopic radical nephrectomy by reviewing the anatomic relationship between the kidney and the adrenal gland.

Methods

From June 2010 to October 2012, a total of 68 patients (45 males and 23 females) with localized renal cell carcinoma were treated at our hospital. The study included 35 cases that were right side and 33 cases that were left, and average patient age was 54.06 years. The average tumor size was 4.7 cm. Tumors were classified via the TNM staging system. All patients underwent adrenal gland-sparing surgery based on retroperitoneal laparoscopic radical nephrectomy.

Results

For each patient, surgery was successful without conversion to open surgery. The average operative time was 56.65 ± 26.60 min, and the mean blood loss was 70.61 ± 60.96 ml. All patients were discharged from the hospital 3 to 8 days after surgery. During surgery, the adrenal gland was slightly lacerated in three cases and the peritoneum showed perforation in six cases. Only one case recurred during the study follow-up.

Conclusions

Based on retroperitoneal laparoscopy radical nephrectomy, this effective adrenal gland-sparing surgery showed direct exposure of tissue and little interference of the upper pole of the kidney. Elevation of the adrenal gland could help with the complete dissection of the adrenal gland from the kidney. The separation of the kidney was rapid, simple and accurate. The probability of adrenal gland damage was reduced. This strategy is recommended for widespread use in T1-2 renal neoplasms.

Comparison of 1,800 laparoscopic and open partial nephrectomies for single renal tumors.

Inderbir Gill, Louis R. Kavoussi, Brian Lane … (2007)

Laparoscopic partial nephrectomy is an increasingly performed, minimally invasive alternative to open partial nephrectomy. We compared early postoperative outcomes in 1,800 patients undergoing open partial nephrectomy by experienced surgeons with the initial experience with laparoscopic partial nephrectomy in patients with a single renal tumor 7 cm or less. Data on 1,800 consecutive open or laparoscopic partial nephrectomies were collected prospectively or retrospectively in tumor registries at 3 large referral centers. Demographic, intraoperative, postoperative and followup data were compared between the 2 groups. Compared to the laparoscopic partial nephrectomy group of 771 patients the 1,028 undergoing open partial nephrectomy were a higher risk group with a greater percent presenting symptomatically with decreased performance status, impaired renal function and tumor in a solitary functioning kidney (p<0.0001). More tumors in the open partial nephrectomy group were more than 4 cm and centrally located and more proved to be malignant (p<0.0001 and 0.0003, respectively). Based on multivariate analysis laparoscopic partial nephrectomy was associated with shorter operative time (p<0.0001), decreased operative blood loss (p<0.0001) and shorter hospital stay (p<0.0001). The chance of intraoperative complications was comparable in the 2 groups. However, laparoscopic partial nephrectomy was associated with longer ischemia time (p<0.0001), more postoperative complications, particularly urological (p<0.0001), and an increased number of subsequent procedures (p<0.0001). Renal functional outcomes were similar 3 months after laparoscopic and open partial nephrectomy with 97.9% and 99.6% of renal units retaining function, respectively. Three-year cancer specific survival for patients with a single cT1N0M0 renal cell carcinoma was 99.3% and 99.2% after laparoscopic and open partial nephrectomy, respectively. Early experience with laparoscopic partial nephrectomy is promising. Laparoscopic partial nephrectomy offered the advantages of less operative time, decreased operative blood loss and a shorter hospital stay. When applied to patients with a single renal tumor 7 cm or less, laparoscopic partial nephrectomy was associated with additional postoperative morbidity compared to open partial nephrectomy. However, equivalent functional and early oncological outcomes were achieved.

Radical nephrectomy for pT1a renal masses may be associated with decreased overall survival compared with partial nephrectomy.

R Thompson, Stephen A. Boorjian, Christine M. Lohse … (2008)

We reviewed our surgical experience with small renal tumors, comparing overall survival in patients treated with radical and partial nephrectomy. Using our nephrectomy registry we identified patients with sporadic, unilateral, solitary and localized renal masses 4 cm or less who underwent radical or partial nephrectomy between 1989 and 2003. Patients with a solitary kidney or impaired renal function at presentation were excluded, leaving 648 available for analysis. Overall survival was estimated using the Kaplan-Meier method and associations with death were evaluated using Cox proportional hazards regression. At last followup 146 patients had died of any cause and 502 were alive at a median of 7.1 years. Radical and partial nephrectomy was performed in 290 and 358 patients, respectively. In all patients radical nephrectomy was not significantly associated with death from any cause compared with partial nephrectomy (RR 1.12, p = 0.52). However, there was a significant interaction with age, leading us to stratify our analysis at the median age of 65 years. In 327 patients younger than 65 years radical nephrectomy was significantly associated with death from any cause compared with partial nephrectomy (RR 2.16, p = 0.02). The increased risk of death persisted after adjusting for year of surgery (p = 0.02), preoperative creatinine (p = 0.03), Charlson-Romano index (p = 0.04), symptoms at presentation (p = 0.02), diabetes at presentation (p = 0.03) and histology (p = 0.02). Our results suggest that, compared with partial nephrectomy, radical nephrectomy is associated with decreased overall survival in younger patients with small renal masses.

Adjuvant autologous renal tumour cell vaccine and risk of tumour progression in patients with renal-cell carcinoma after radical nephrectomy: phase III, randomised controlled trial.

Dieter Jocham, Walter Lehmacher, Viatcheslav G Zakrzewski … (2004)

Organ-confined renal-cell carcinoma is associated with tumour progression in up to 50% of patients after radical nephrectomy. At present, no effective adjuvant treatment is established. We aimed to investigate the effect of an autologous renal tumour cell vaccine on risk of tumour progression in patients with stage pT2-3b pN0-3 M0 renal-cell carcinoma. Between January, 1997, and September, 1998, 558 patients with a renal tumour scheduled for radical nephrectomy were enrolled at 55 institutions in Germany. Before surgery, all patients were centrally randomised to receive autologous renal tumour cell vaccine (six intradermal applications at 4-week intervals postoperatively; vaccine group) or no adjuvant treatment (control group). The primary endpoint of the trial was to reduce the risk of tumour progression, defined as progression or death. All patients were assessed after standardised diagnostic investigations at 6-month intervals for a minimum of 4.5 years. By preoperative and postoperative inclusion criteria, 379 patients were assessable for the intention-to-treat analysis. At 5-year and 70-month follow-up, the hazard ratios for tumour progression were 1.58 (95% CI 1.05-2.37) and 1.59 (1.07-2.36), respectively, in favour of the vaccine group (p=0.0204, log-rank test). 5-year and 70-month progression-free survival rates were 77.4% and 72%, respectively, in the vaccine group and 67.8% and 59.3%, respectively, in the control group. The vaccine was well tolerated, with only 12 adverse events associated with the treatment. Adjuvant treatment with autologous renal tumour cell vaccine in patients with renal-cell carcinoma after radical nephrectomy seems to be beneficial and can be considered in patients undergoing radical nephrectomy due to organ-confined renal-cell carcinoma of more than 2.5 cm in diameter.
