Background and objectives: Cryoablation is emerging as a safe and effective therapeutic option for treating renal cell carcinoma. This study analyzed the safety and long-term oncological outcomes of cryoablation in our center. Materials and methods: Patients who underwent computed tomography (CT)-guided percutaneous cryoablation between February 2011 and June 2020 for one or more clinically localized renal tumors were identified. Technical success and treatment efficacy were assessed. Post-procedural complications were classified according to the Clavien-Dindo system. Recurrence–free survival was determined for biopsy-proven malignant renal tumors. Results: A total of 174 renal tumors, 78 of which were biopsy-proven malignant carcinomas, were treated in 138 patients (97 males and 41 females, mean age: 73 years, range: 43–89 years). Mean tumor size was 2.25 cm and 54.6% of the lesions required a complex approach. Technical success was achieved in 171 out of 174 tumors (98.3%). Primary treatment efficacy was 95.3% and increased to 98.2% when retreats were taken into account. The overall complication rate was 29.8%. No complications of Clavien-Dindo grade III or more were encountered. Median follow-up was 21.92 months (range: 0.02–99.87). Recurrence-free survival was 100% at 1 year, 95.3% (95% CI: 82.1%–98.8%) at 3 years, and 88.6% (95% CI: 71.8%–95.7%) at 5 years. Conclusions: Cryoablation is a safe and effective technique for the treatment of small renal lesions, with no major complications when performed by expert interventional radiologists. The multidisciplinary discussion is essential, especially considering the high number of histologically undetermined lesions. Our long-term oncological outcomes are encouraging and in line with the literature.

Abstract Purpose To retrospectively investigate long-term outcomes of renal cryoablation from a multicenter database. Methods 338 patients with 363 renal tumors underwent cryoablation in 4 centers in North-Eastern Italy. 340/363 tumors (93.7%) were percutaneously treated with CT guidance. 234 (68.8%) were treated after conscious sedation, 76 (22.3%) under local lidocaine anesthesia only and 30 (8.8%) under general anesthesia. Treatment efficacy and complication rate considered all procedures. Oncologic outcomes considered a subset of 159 patients with 159 biopsy proven renal cell carcinoma. Results Mean tumor size was 2.53 cm. Technical success was achieved in 355/363 (97.8%) treatments. Treatment efficacy after the first treatment was achieved in 348/363 (95.9%) tumors. Statistical analysis revealed a significant lower treatment efficacy for ASA score >3, Padua score >8, tumor size >2.5 cm, use of >2 cryoprobes, presence of one single kidney. In the subset of 159 patients, recurrence-free survival rates were 90.5% (95% CI 83.0%, 94.9%) at 3 years and 82.4% (95% CI 72.0%, 89.4%) at 5 years; overall survival rates were 96.0% (95% CI 90.6%, 98.3%) at 3 years and 91.0% (95% CI 81.7%, 95.7%) at 5 years; no patient in this subset developed metastatic disease. Clavien-Dindo >1 complications were recorded in 14/369 procedures (3.8%) and were related to age >70 years, tumor size >4 cm and use of >2 cryoprobes. Conclusion Cryoablation performed across four different centers in a large cohort of predominantly small renal tumors showed that this technique provides good recurrence-free survival rates and overall survival rates at three- and five-year with very low major complications rate.

Objective: Recently, the laparoscopic technique has become widely accepted as a minimally invasive modality which reduces morbidity and provides similar oncological outcomes to open surgery. However, the number of clinical trials comparing laparoscopic and open radical cystectomy are limited. The objectives of this study are to compare the long-term oncological outcomes between open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) for bladder cancer. Materials and Methods: Out of 144 radical cystectomy patients admitted to our institute from January 2006 to December 2016, 87 patients were categorized as being in the LRC group, and 57 patients in the ORC group. Baseline characteristics, perioperative variables, and pathology results were collected retrospectively. Oncological outcomes including overall survival (OS), recurrence-free survival (RFS) and cancer-specific survival (CSS) were analyzed and compared between the two groups. Results: The mean age of the patients was 64.19 ± 9.89 years in the ORC group and 61.90 ± 10.47 years in the LRC group. The most frequent urinary diversion procedure in both groups was ileal conduit. All pathology results between the LRC group and the ORC group showed no statistical significance. The median follow-up duration was 57.18 ± 44.68 months in the ORC group and 53.96 ± 34.97 months in the LRC group. There was no statistically significant difference in overall survival (OS), recurrence-free survival (RFS) and cancer-specific survival (CSS) between the groups (p = 0.322, 0.946, and 0.528, respectively). Conclusion: Our study demonstrated that the long-term oncological outcome of LRC is comparable to ORC in the management of bladder cancer. LRC is an alternative option to open radical cystectomy and is safe, effective, and feasible. However, further large comparative studies with adequate long-term follow-up are recommended to support our results.

Abstract Background Non-steroidal anti-inflammatory drugs (NSAIDs) are known to suppress the inflammatory response after surgery and are often used for pain control. This study aimed to investigate NSAID use after radical surgical resection for rectal cancer and long-term oncological outcomes. Methods A cohort of patients who underwent anterior resection for rectal cancer between 2007 and 2013 in 15 hospitals in Sweden was investigated retrospectively. Data were obtained from the Swedish Colorectal Cancer Registry and medical records; follow-up was undertaken until July 2019. Patients who received NSAID treatment for at least 2 days after surgery were compared with controls who did not, and the primary outcome was recurrence-free survival. Cox regression modelling with confounder adjustment, propensity score matching, and an instrumental variables approach were used; missing data were handled by multiple imputation. Results The cohort included 1341 patients, 362 (27.0 per cent) of whom received NSAIDs after operation. In analyses using conventional regression and propensity score matching, there was no significant association between postoperative NSAID use and recurrence-free survival (adjusted hazard ratio (HR) 1.02, 0.79 to 1.33). The instrumental variables approach, including individual hospital as the instrumental variable and clinicopathological variables as co-variables, suggested a potential improvement in the NSAID group (HR 0.61, 0.38 to 0.99). Conclusion Conventional modelling did not demonstrate an association between postoperative NSAID use and recurrence-free survival in patients with rectal cancer, although an instrumental variables approach suggested a potential benefit.

Partial nephrectomy has become a treatment of choice for clinical T1a renal masses. Some international guidelines suggest that partial nephrectomy can be applied also in clinical T1b tumors. The aim of this study was to evaluate the feasibility of partial nephrectomy for tumors larger than 4 cm. We reviewed the medical records of 1280 patients who underwent partial nephrectomy and had pathologically confirmed malignancy. Patients were categorized into two groups by the size of tumors on computed tomography image, with a cutoff value of 4 cm. The oncologic and functional outcomes were compared between the two groups. Recurrence-free survival after surgery was estimated using the Kaplan-Meier method. Of the 1280 patients, 203 patients (15.9%) had renal tumors larger than 4 cm. There were significantly more exophytic tumors (P < 0.001) and the R.E.N.A.L. scores were significantly higher (P < 0.001) in partial nephrectomy >4 cm. Mean ischemic times were significantly different (P < 0.001). After 24 months, mean creatinine level between partial nephrectomy >4 cm and partial nephrectomy ≤4 cm was not different significantly (P = 0.554). And the percent changes of glomerular filtration rate after partial nephrectomy were not different at last follow-up (P = 0.082). The 5-year recurrence-free survival rates were 96.6% in partial nephrectomy ≤4 cm, and 94.5% in partial nephrectomy >4 cm (P = 0.416). Based on the present findings, partial nephrectomy for tumors larger than 4 cm showed comparable feasibility and safety to partial nephrectomy for tumors ≤4 cm considering oncologic and functional outcomes, despite longer operative and ischemic time.

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes.Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of <25 minutes. In addition, we analyzed pathological and oncological outcomes; recurrence, metastasis, all-cause deaths, cancer-specific deaths, and 5-year survival rates.Results: In 1,002 cases, the Trifecta achievement was 61.1% (n=612). The postoperative complication was 18.4% (n=184) but most were grade 2 or less (14.9%, n=145). Ninety-three cases (9.28%) had benign and 907 cases (90.5%) had malignant pathologies. A local recurrence were 14 cases (1.54%) and distant metastasis were 20 cases (2.2%) during follow-up periods. Allcause death rate was 1.2% (n=11) and cancer-specific death rate was 0.2% (n=2). The median follow-up period was 39 months. A 5-year recurrence-free survival rate, cancer-specific survival rate, and overall survival rate were 95.2%, 99.7%, and 98.4%.Conclusions: In summary, our data shows comparable perioperative outcomes to other largescale studies of RPN in terms of the Trifecta achievement with similar baseline characteristics. In terms of oncological outcomes, there was lower rate of PSM and similar recurrence free survival rate.

Objective The effect of postoperative complications including red blood transfusion (BT) on long-term survival for hepatocellular carcinoma (HCC) is unknown. The purpose of this study was to define the relationship between postoperative complications and long-term survival in patients with HCC. Methods Postoperative complications of 1251 patients who underwent curative liver resection for HCC were classified, and their recurrence-free survival (RFS) and cumulative overall survival (OS) were investigated. Results Any complications occurred in 503 patients (40%). Five-year RFS and 5-year OS in the complication group were 21% and 56%, respectively, significantly lower than the respective values of 32% ( p &lt; 0.001) and 68% ( p &lt; 0.001) in the no-complication group (n=748). Complications related to RFS were postoperative BT [Hazard ratio (HR): 1.726, 95% confidence interval (CI): 1.338–2.228, p &lt; 0.001], pleural effusion [HR: 1.434, 95% CI: 1.200–1.713, p &lt; 0.001] using Cox-proportional hazard model. Complications related to OS were postoperative BT [HR: 1.843, 95%CI: 1.380-2.462, p &lt; 0.001], ascites [HR: 1.562, 95% CI: 1.066–2.290 p = 0.022], and pleural effusion [HR: 1.421, 95% CI: 1.150–1.755, p = 0.001). Conclusions Postoperative complications were factors associated with poor long-term survival. Postoperative BT and pleural effusion, were noticeable complications that were prognostic factors for both recurrence-free survival and overall survival.

Abstract Background Local excision might represent an alternative to total mesorectal excision for patients with locally advanced rectal cancer who achieve a major or complete clinical response after neoadjuvant chemoradiotherapy. Methods Between August 2005 and July 2011, 63 patients with mid-low rectal adenocarcinoma who had a major/complete clinical response after neoadjuvant chemoradiotherapy were enrolled in a multicenter prospective phase 2 trial and underwent transanal full thickness local excision. The main endpoint of this study was to evaluate the 5- and 10-year overall, relapse-free, local, and distant relapse-free survival, which were calculated by applying the Kaplan–Meier method. The rate of patients with rectum preserved and without stoma were also calculated. Results Of 63 patients, 38 (60%) were male and 25 (40%) were female, with a median (range) age of 64 (25–82) years. At baseline, the following clinical stages were found: cT2, n = 21 (33.3%); cT3, n = 42 (66.6%), 39 (61.9%) patients were cN+. At a median (range) follow-up of 108 (32–166) months, the estimated cumulative 5- and 10-year overall survival, relapse-free survival, local recurrence-free survival, and distant recurrence-free survival were 87% (95% CI 76–93) and 79% (95% CI 66–87), 89% (95% CI 78–94) and 82% (95% CI 66–91), both 91% (95% CI 81–96), and 90% (95% CI 80–95) and 86% (95% CI 73–93), respectively. Overall, 49 (77.8%) patients had their rectum preserved, and 54 (84.1%) were stoma-free. Conclusion In highly selected patients, the local excision approach after neoadjuvant chemoradiotherapy is associated with excellent long-term outcomes, high rates of rectum preservation and absence of permanent stoma.

Abstract OBJECTIVES Although the standard treatment for pathological N2 (pN2) non-small-cell lung cancer (NSCLC) patients is definitive chemoradiation, surgery can be beneficial for resectable pN2 disease. Herein, we report the long-term clinical outcomes of upfront surgery followed by adjuvant treatment for selected patients with resectable pN2 disease. METHODS We performed a retrospective analysis of clinical outcomes for patients with pN2 disease who underwent surgery as the first-line therapy. Multivariable Cox regression analysis was used to identify the significant factors for overall survival (OS) and recurrence-free survival. RESULTS From 2004 to 2015, a total of 706 patients with pN2 NSCLC underwent complete anatomical resection at our institution. The patients’ clinical N stages were cN0, 308 (43.6%); cN1, 123 (17.4%) and cN2, 275 (39.0%). Adjuvant chemotherapy, radiotherapy and chemoradiotherapy were administered to 169 (23.9%), 115 (17.4%) and 299 patients (42.4%), respectively. With a median follow-up of 40 months, the respective median time and 5-year rate of OS were 52 months and 44.7%. According to subdivided pN2 descriptors, the median OS time was 80, 53 and 37 months for patients with pN2a1, pN2a2 and pN2b, respectively. Adjuvant chemotherapy was a significant prognostic factor for both OS [hazard ratio (HR) 0.39, 95% confidence interval (CI) 0.28–0.52; P &lt; 0.001] and recurrence-free survival (HR 0.42, 95% CI 0.30–0.58; P &lt; 0.001). CONCLUSIONS Upfront surgery followed by adjuvant therapy for resectable N2 disease showed favourable outcomes compared to those reported in previous studies. Adjuvant chemotherapy is essential to improve the prognosis for patients undergoing upfront surgery for N2 disease.
