In the early 1950s, Rubin H. Flocks of the University of Iowa began to treat prostate cancer patients with colloidal gold (Au198) therapy, evolving his technique over nearly 25 years in 1515 patients. We reviewed the long-term outcomes of Flocks' prostate cancer patients as compared to those patients treated by other methods at the University of Iowa before Flocks' chairmanship. We reviewed archived patient records, Flocks' published data, and long-term survival data from the Iowa Tumor Registry to determine short- and long-term outcomes of Flocks' work with colloidal gold. We also reviewed the literature of Flocks' time to compare his outcomes against those of his contemporaries. The use of colloidal gold, either as primary or adjunctive therapy, provided short- and long-term survival benefit for the majority of Flocks' patients as compared to historical treatment options (p< 0.001). Flocks' use of colloidal gold for the treatment of locally advanced prostate cancer offered short- and long-term survival benefits compared to other contemporary treatments.

Abstract   Nowadays, there is still no consensus about the benefits of adding neck lymphadenectomy to the traditional two-fields esophagectomy. An extended lymphadenectomy could potentially increase operation time and the risks for postoperative complications. However, extended lymphadenectomy allows resection of cervical nodes at risk for metastases, potentially increasing long-term survival rates. This study aims to estimate whether cervical prophylactic lymphadenectomy for esophageal cancer influences short- and long-term outcomes through a systematic review of literature and meta-analysis. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central, and Lilacs (BVS). The inclusion criteria were: (1) studies that compare two-field vs. three-field esophagectomy; (2) adults (&gt;18 years); (3) articles that analyze short- or long-term outcomes; and (4) clinical trials or cohort studies. The results were summarized by forest plots, with effect size (ES) or risk difference (RD) and 95% CI. Results Twenty-five articles were selected, comprising 8,954 patients. Three-field lymphadenectomy was associated to higher operation time (ES: -1.51; 95%CI -1.84, −1.18) and higher blood loss (ES: -0.24; 95%CI: −0.37, −0.11). Also, neck lymphadenectomy inputs additional risk for pulmonary complications (RD: 0.03; 95%CI: 0.01, 0.05). No difference was noted for morbidity (RD: 0.01; 95%CI: −0.01, 0.03); leak (−0.02; 95%CI: −0.07, 0.03); postoperative mortality (RD: 0.00; 95%CI: −0.00, 0.01), and hospital stay (ES: -0.05; 95%CI -0.20, 0.10). Three-field lymphadenectomy allowed higher number of retrieved lymph nodes (MD: -1.51; 95%CI -1.84, −1.18), but did not increase the overall survival (HR: 1.11; 95%CI: 0.96, 1.26). Conclusion Prophylactic neck lymphadenectomy for esophageal cancer should be performed with caution once it is associated with poorer short-term outcomes compared to traditional two-field lymphadenectomy and does not improve long-term survival. Future esophageal cancer studies should determine the subgroup of patients who could benefit from prophylactic neck lymphadenectomy in long-term outcomes.

Objective To evaluate the effect of vascular resection (VR), including portal vein resection (PVR) and hepatic artery resection (HAR), on short- and long-term outcomes in patients with perihilar cholangiocarcinoma (PHC). Background Resection surgery and transplantation are the main treatment methods for PHC that provide a chance of long-term survival. However, the efficacy and safety of VR, including PVR and HAR, for treating PHC remain controversial. Methods This study was registered at the International Prospective Register of Systematic Reviews (CRD42020223330). The EMBASE, PubMed, and Cochrane Library databases were used to search for eligible studies published through November 28, 2020. Studies comparing short- and long-term outcomes between patients who underwent hepatectomy with or without PVR and/or HAR were included. Random- and fixed-effects models were applied to assess the outcomes, including morbidity, mortality, and R0 resection rate, as well as the impact of PVR and HAR on long-term survival. Results Twenty-two studies including 4,091 patients were deemed eligible and included in this study. The meta-analysis showed that PVR did not increase the postoperative morbidity rate (odds ratio (OR): 1.03, 95% confidenceinterval (CI): [0.74–1.42], P = 0.88) and slightly increased the postoperative mortality rate (OR: 1.61, 95% CI [1.02–2.54], P = 0.04). HAR did not increase the postoperative morbidity rate (OR: 1.32, 95% CI [0.83–2.11], P = 0.24) and significantly increased the postoperative mortality rate (OR: 4.20, 95% CI [1.88–9.39], P = 0.0005). Neither PVR nor HAR improved the R0 resection rate (OR: 0.70, 95% CI [0.47–1.03], P = 0.07; OR: 0.77, 95% CI [0.37–1.61], P = 0.49, respectively) or long-term survival (OR: 0.52, 95% CI [0.35–0.76], P = 0.0008; OR: 0.43, 95% CI [0.32–0.57], P < 0.00001, respectively). Conclusions PVR is relatively safe and might benefit certain patients with advanced PHC in terms of long-term survival, but it is not routinely recommended. HAR results in a higher mortality rate and lower overall survival rate, with no proven benefit.

Abstract. Background: We analyses the effect of gender on short and long-term morbidity and mortality in carotid endarterectomy (CEA) under loco-regional anesthesia. Patients and methods: Patients who were entered into a prospectively compiled computerized database of unilateral, consecutive CEAs performed at our hospital from January 2000 to December 2010 were analysed. Endpoints were perioperative stroke and death, and overall long-term survival rates. Statistical analysis was used to determine the relationships between gender and outcomes after CEA. A Cox proportional hazard model was applied to determine independent risk factors for long term survival. Results: A total of 1880 CEA procedures were performed in the period between 2000 and 2010. Overall, there were 28 (1.48 %) neurological deficits according to the ipsilateral carotid supply territory, including minor and major strokes. 7 occurred in the female group (1.19 %), and 21 in the male group (1.62 %) with no significant difference between the genders (p = 0.60). No significant difference emerged between female and male patients when postoperative neurological events according to the ipsilateral carotid supply territory were stratified by linical presentation (asymptomatic ICA stenosis: p = 0.75; symptomatic ICA stenosis: p = 0.66). The late overall mortality rate was 4.1% (n = 78) and 26/78 of these late deaths occurred in the female group (33 %). Log rank analysis of Kaplan Meier curves showed no statistically significant difference in long-term survival between the groups (p = 0.74). The multivariate risk factor analysis with the Cox proportinal hazard model revealed age (p < 0.00), and smoking (p = 0,02) as independent risk factors for decreased long term survival. Conclusions: When considering short and long-term outcomes in patients receiving carotid endarterectomy in local anaesthesia gender should not be regarded as a factor on decision-making for carotid interventions in both symptomatic and asymptomatic patients.
