The efficacy of laparoscopic radical nephrectomy for renal cell cancer in the elderly: An oncological outcome analysis

Efficacy and safety of surgery in renal carcinoma patients 75 years and older: a retrospective analysis

Objective

To investigate the efficacy and complications of surgical treatment in patients with renal cell carcinoma aged ≥ 75 years.

Methods

From January 2009 to May 2019, we assessed 166 patients aged 75 years and older, who either had radical nephrectomy (RN) or partial nephrectomy (PN) as treatments for diagnosed renal cell carcinoma. Patients were divided into one group of patients aged 75–79 years and the second group of patients ≥ 80 years. The complications and survival were compared between the two groups.

Results

All 166 patients were successfully operated on. Differences between the two groups were statistically significant in intraoperative and postoperative complications and Clavien–Dindo score of ≥ 1 (P = 0.02, P < 0.001, P = 0.001). Univariate analysis revealed no significant correlation between a Clavien–Dindo score ≥ 1 versus gender, body mass index (BMI), lack of symptoms, KPS, baseline GFR, postoperative GFR, tumor size, tumor location, surgical method, and transfusion or no transfusion (ALL P > 0.05). Multifactor analysis showed that age ≥ 80 years, partial nephrectomy, and operation time were independent predictors of a Clavien–Dindo score ≥ 1. No significant difference was found in OS between the two groups, (P < 0.0001), and no significant difference in CSS (P = 0.056). There was no significant difference in OS and CSS between the RN and PN groups (P = 0.143, P = 0.281, respectively).

Conclusions

According to our findings, the overall safety of surgical therapy for elderly patients with renal cell carcinoma is adequate. PN should be carefully examined, especially over the age of 80. To select suitable patients based on an assessment of the tumor's complexity and patients' physical condition, such as age, underlying diseases and other conditions, technical feasibility, balance of benefits and a case-by-case.

Robotic surgical staging for endometrial and cervical cancers in medically ill patients

OBJECTIVES

Patients with high anesthesiological risk due to old age, obesity and severe co-morbidities alone or in combination are considered as poor candidates for extensive surgical staging procedures, especially if through minimally invasive approach. We aimed to evaluate the feasibility and safety of robotic surgical staging of endometrial and cervical cancers in the medically ill patient.

METHODS

Between 07-2007 and 12-2012, consecutive patients scheduled for staging for endometrial or cervical cancer were directed towards robotic staging and divided into two groups according to their starting score in the American Society for Anaesthesiologists (ASA): Group 1 (ASA 1-2) and Group 2 (ASA ≥3).

RESULTS

Overall, 169 (71.9%) patients had ASA 1-2 whereas 66 (28.1%) had ASA ≥3. ASA ≥3 were older (p<0.0001) with a greater proportion of co-morbidities (p<0.0001), as well as of Class II (4.7% vs 19.7%; p=0.0007) and Class III obesity (2.4% vs 31.8%; p<0.0001). No differences were found between groups in terms of operative time, blood loss, intra- and post-operative complications, conversion rate and hospitalization. No differences were recorded either in terms of staging procedures performed or in terms of number of pelvic (p=0.72) and para-aortic (p=0.86) lymph nodes retrieved.

CONCLUSIONS

Despite theoretical concerns about the performance of robotic surgery in patients with high anesthesiological risk, our experience showed that robotics is a feasible, safe and viable option for the management of endometrial and cervical cancers also in this more vulnerable group of patients.

Wide range and variation in minimally invasive surgery for renal malignancy in Japan: a population-based analysis

BACKGROUND

Despite increasing interest in minimally invasive surgery, prevalence data are completely absent. Our objective was to analyze clinico-epidemiological variations of surgery for renal malignancy in Japan with emphasis on annual trends and regional gaps, and to analyze factors affecting choice of open versus minimally invasive surgery.

METHODS

We identified patients who underwent open (n = 8646), laparoscopic (n = 5932), or minimum incision endoscopic surgery (MIES) (n = 381) nephrectomy for renal malignancy, using the Japanese Diagnosis Procedure Combination database, 2007-2010. Clinical and regional variations in these three approaches were determined, and the annual per-population incidence of nephrectomy was estimated. Multivariate logistic regression was used to analyze factors affecting choice of minimally invasive surgery (laparoscopy or MIES).

RESULTS

The proportion of open nephrectomy decreased from 65.3 % in 2007 to 51.6 % in 2010. Laparoscopic nephrectomy accounted for 51.0 % of procedures for T1 tumors. The estimated incidence of nephrectomy in males and females was 14.3 and 6.1 per 100,000 person-years, respectively. Multivariate analysis showed that minimally invasive nephrectomy was more likely to be selected for patients in their 30-50s who had less comorbidity, better performance status, or lower TNM stage, in high-volume or academic hospitals, especially in western Japan. Hemodialysis use was a favorable factor.

CONCLUSION

Despite differences between eastern and western Japan, minimally invasive surgery is becoming widespread throughout Japan, especially for patients with low operative risks and early-stage cancer who are hospitalized in high-volume institutes.

Surgical and survival outcomes in older women with endometrial cancer treated by laparoscopy

OBJECTIVE

The aim of this study was to evaluate the feasibility and safety of laparoscopic surgical management of apparently early-stage endometrial cancer in older women and to compare clinical outcomes between older and younger women.

METHODS

Our prospective oncological database was retrospectively reviewed to identify all consecutive women who underwent surgery for endometrial cancer from 2002. Data available included information about demography, comorbidities, surgical outcomes, histology, adjuvant therapies, and follow-up. Women were divided in two groups according to age (older, >65 y, and younger, < or =65 y). Univariate and multivariate analyses were performed to identify factors that negatively impact disease-free and overall survival.

RESULTS

A total of 48 (44.4%) older and 60 (55.6%) younger women were included. Groups were comparable in operative time, blood loss, need for blood transfusions, nodal count, and intraoperative and postoperative complications. Cancer in older women was more frequently upstaged than that in younger women (17 [35.4%] vs 8 [13.3%], respectively; P = 0.01). The 2- and 5-year disease-free survival rates were 82% versus 96% (P = 0.003) and 74% versus 93% (P = 0.0005) and the overall 2- and 5-year survival rates were 87% versus 98% (P = 0.006) and 83% versus 95% (P = 0.01) for older and younger women, respectively. Multivariate analysis showed that advanced surgical stage, unfavorable histology, high-grade tumors (grade 3), and deep myometrial invasion (>50%) are independent risk factors for recurrence.

CONCLUSIONS

In the absence of absolute anesthesia contraindications, laparoscopy seems to be feasible and safe in older women with endometrial cancer. Comprehensive surgical staging should be offered, regardless of age, to avoid understaging and to optimize treatment strategies.
