803 Outcomes of Radical Nephroureterectomy: An Australian Multicentre Experience Using a Dedicated Upper Tract Data Registry

Abstract Introduction Radical nephroureterectomy (RNU) is used for the treatment of upper tract urothelial carcinoma (UTUC). It is a procedure with considerable morbidity. Australian data on UTUC is limited, and we have recently developed the ACCEPT-U database to try and address this. This study aims to examine the surgical and oncological outcomes in patients who have undergone RNU. Method We collected data using the ACCEPT-U database on patients who underwent (RNU) across two tertiary centres in Victoria and Western Australia between 2013 and 2022. Our primary outcomes were overall survival at one, two, and five years. Our secondary outcomes included postoperative complications and recurrence data. Results One hundred and one patients underwent RNU during the study period. The median age was 73 (IQR 64.0 to 80.5) years. The median hospital length of stay was 7 days (IQR 5-11) overall. Neither operative technique, CCI nor age affected hospital length of stay (p >0.05). The 30-day post-operative complication rate was 35% (n=35), with a median Clavien Dindo of II. Overall survival rates at one, two, and five years were 89%. (95% CI 81.4 - 94.0%); 79% (95% CI 70.2 - 86.1%) and 73% (95% CI 63.9 – 81.0%). Advanced pathological stage was associated with reduced overall 5-year survival (Pearson Chi-Squared = 10.40, p=0.006). Conclusions Radical nephroureterectomy in patients with UTUC has considerable morbidity and mortality in Australian centres but this appears comparable to published rates. The ACCEPT-U database will facilitate larger and prospective data collection, hopefully across multiple institutions, to further assess peri-operative outcomes and their determinants in the future.

Lymph Node Yield is Associated with Improved Overall Survival and Increased Time to Recurrence in Node-Negative Pancreatic Ductal Adenocarcinoma Following Neoadjuvant Therapy.

To determine if lymph node yield (LNY) is associated with improved overall survival (OS) and time to recurrence (TTR) in patients with node-negative pancreatic ductal adenocarcinoma (PDAC) treated with neoadjuvant therapy (NAT). Lymph node yield has been associated with survival in solid gastrointestinal cancers, including PDAC. Patients with pathological T stage I-III, node-negative (N0), PDAC treated with NAT followed by pancreatoduodenectomy were identified in the Massachusetts General Hospital (MGH) pancreatectomy database and the National Cancer Database (NCDB). A cutoff point of 22 nodes was identified in the NCDB using the point with the optimal (log-rank test) split. Overall survival and TTR were evaluated using univariate and multivariable analyses. In the MGH cohort, 233 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (59 months vs. 25 months, P<0.001) and prolonged TTR (32 months vs. 14 months, P=0.019). On multivariable analysis, LNY was an independent predictor of survival (HR 0.97, 95% CI 0.95-0.99, P=0.034) per sampled node. In the NCDB, 2,029 node-negative patients following NAT were included. A LNY ≥ 22 was associated with prolonged median OS (49 months vs. 33 months, P<0.001). On multivariable analysis, LNY was an independent predictor of survival (HR 0.99, 95% CI 0.98-0.99, P<0.001) per sampled node. Lymph node yield was associated with improved oncologic outcomes in patients treated with NAT followed by pancreatoduodenectomy in two independent datasets. Responsible mechanisms by which LNY impacts the outcomes of node-negative patients following NAT warrant further exploration.

Lessons For COVID-19 Era: Impact of Delays in Surgery on Biochemical Recurrence-Free Survival and Adverse Oncological Outcomes in Patients with Prostate Cancer

Clinical features and prediction of long-term survival after surgery for perihilar cholangiocarcinoma.

The treatment of perihilar Cholangiocarcinoma (pCCA) poses specific challenges not only due to its high perioperative complication rates but also due its dismal long-term prognosis with only a few long-term survivors (LTS) among the patients. Therefore, in this analysis characteristics and predictors of LTS in pCCA patients are investigated. In this single center analysis, patients undergoing curative-intent liver resection for pCCA between 2010 and 2022 were categorized into long-term and short-term survivors (STS) excluding perioperative mortality. Binary logistic regression was used to determine key differences between the groups and to develop a prognostic composite variable. This composite variable was subsequently tested in the whole cohort of surgically treated pCCA patients using Cox Regression analysis for cancer-specific survival (CSS). Within a cohort of 209 individuals, 27 patients were identified as LTS (median CSS = 125 months) and 55 patients as STS (median CSS = 16 months). Multivariable analysis identified preoperative portal vein infiltration (OR = 5.85, p = 0.018) and intraoperative packed red blood cell (PRBC) transfusions (OR = 10.29, p = 0.002) as key differences between the groups. A prognostic composite variable based on these two features was created and transferred into a Cox regression model of the whole cohort. Here, the composite variable (HR = 0.35, p<0.001), lymph node metastases (HR = 2.15, p = 0.001) and postoperative complications (HR = 3.06, p<0.001) were identified as independent predictors of CSS. Long-term survival after surgery for pCCA is possible and is strongly negatively associated with preoperative portal vein infiltration and intraoperative PRBC transfusion. As these variables are part of preoperative staging or can be modulated by intraoperative technique, the proposed prognostic composite variable can easily be transferred into clinical management to predict the oncological outcome of patients undergoing surgery for pCCA.

Implications of unconventional histological subtypes on magnetic resonance imaging and oncological outcomes in patients who have undergone radical prostatectomy

The prognostic significance of unconventional histology (UH) subtypes including intraductal carcinoma of the prostate (IDC-P), ductal adenocarcinoma, and cribriform pattern has been investigated for prostate cancer (PCa). However, little is known about magnetic resonance imaging (MRI) features and the oncological impact of tumor localization in localized PCa with UH. Clinical data of 211 patients with acinar adenocarcinoma (conventional histology [CH]) and 82 patients with UH who underwent robotic-assisted radical prostatectomy (RARP) were reviewed. Patients with UH are more likely to be older and have higher Gleason grade group, higher Prostate Imaging-Reporting and Data System (PI-RADS) v2.1 score, and larger tumor volume (TV) than those with CH. Multivariate analysis identified the presence of UH as an independent prognostic factor for progression-free survival (PFS) (hazard ration (HR) 2.41, 95% confidence interval (CI) 0.22–0.79, P = 0.0073). No significant difference in PFS was seen regarding tumor localization (transition zone [TZ] or peripheral zone [PZ]) in patients with UH (P = 0.8949), whereas PZ cancer showed shorter PFS in patients with CH (P = 0.0174). PCa with UH was associated with higher progression than PCa with CH among resection margin (RM)-negative cases (P < 0.0001). Further, increased PI-RADS v2.1 score did not correlate with larger TV in UH (P = 0.991), whereas a significant difference in TV was observed in CH (P < 0.0001). The prognostic significance of UH tumor was independent of tumor localization, and shorter PFS was observed even in RM-negative cases, indicating an aggressive subtype with micro-metastatic potential. Furthermore, UH tumors are more likely to harbor a large TV despite PI-RADS v2.1 score ≤ 3. These findings will help optimal perioperative management for PCa with UH.

Long-Term Follow-Up of Patients with Advanced Colorectal Liver Metastasis: A Survival Analysis from the Randomized Controlled Multicenter Trial LIGRO

Objective: The objective of this study was to evaluate the long-term oncological outcomes of patients with colorectal liver metastasis (CRLM) randomized for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or 2-stage hepatectomy (TSH). Introduction: For advanced CRLM, TSH or ALPPS may be needed for tumor freedom. The randomized, controlled, multicenter trial LIGRO showed an increased resection rate in patients who underwent ALPPS but no difference in morbidity or mortality. The 2-year survival analysis revealed better overall survival in the ALPPS group. Here, the long-term survival analysis from the LIGRO trial is reported. Methods: In the LIGRO trial, 100 patients were randomized to TSH or ALPPS, with the option of rescue ALPPS if insufficient growth was found after the initial step of TSH. Patients were enrolled between June 2014 and August 2016. Follow-up data for this study were collected between November 2022 and February 2023. Results: In total, 16 patients were alive at the end of the follow-up period. The estimated median follow-up time was 93 months. Estimated median overall survival times were 45 months in the ALPPS group and 27 months in the TSH group (P = 0.057), with 5-year survival rates of 31% and 20%, respectively. Positive prognostic factors were liver tumor-free status at the first follow-up and rectal primary tumor. Negative prognostic factors were extrahepatic disease and increasing CLRM size. Conclusion: Liver tumor-free status is a predictor of long-term survival, along with extrahepatic disease, large CRLM size, and rectal primary tumor. Survival did not significantly differ between patients treated with ALPPS or TSH.

Travel distance does not affect overall survival in patients with appendiceal adenocarcinoma undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

IntroductionCytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a potentially curative approach for appendiceal cancer (AC) with peritoneal dissemination and is most often employed at tertiary referral centers. Regionalization may provide geographic barriers to care for vulnerable patients. The aim of this study was to examine the effect of travel distance on oncologic outcomes of patients with AC treated with CRS-HIPEC. MethodsThe National Cancer Database (NCDB) was reviewed from 2006 through 2020 for patients with AC who underwent CRS-HIPEC. The primary comparison variable was distance (<50 miles vs ≥ 50 miles from the CRS-HIPEC facility). Demographic and tumor characteristics were analyzed. Primary outcome was overall survival (OS). Secondary outcomes were 30-day and 90-day mortality, readmission, and length of stay (LOS). ResultsDuring the study period, 1703 patients met inclusion criteria, with 1000 patients travelling < 50 miles for CRS-HIPEC (59 %) and 703 travelling ≥ 50 miles (41 %). Patients who traveled ≥ 50 miles were more likely to be non-Hispanic White (p < 0.001), have annual income less than $74,062, be treated at an academic center and live in the South-Atlantic region of the United States. There was no significant difference in OS between groups (Figure 1). There were no significant differences in 30-day postoperative survival, 90-day survival, or 30-day readmission. Post-operative LOS was 8.0 versus 9.0 days (p < 0.001). ConclusionsTravel distance ≥ 50 miles was not significantly associated with decreased OS or increased postoperative mortality, suggesting that regionalization of care does not worsen oncologic outcomes for patients with AC undergoing CRS-HIPEC.

Association of Surgical Approaches and Outcomes in Total Mesorectal Excision and Margin Status for Rectal Cancer

IntroductionDespite being a key metric with a significant correlation with the outcomes of patients with rectal cancer, the optimal surgical approach for total mesorectal excision (TME) has not yet been identified. The aim of this study was to assess the association of the surgical approach on the quality of TME and surgical margins and to characterize the surgical and long-term oncologic outcomes in patients undergoing robotic, laparoscopic, and open TME for rectal cancer. MethodsPatients with primary, nonmetastatic rectal adenocarcinoma who underwent either lower anterior resection or abdominoperineal resection via robotic (Rob), laparoscopic (Lap), or open approaches were selected from the US Rectal Cancer Consortium database (2007-2017). Quasi-Poisson regression analysis with backward selection was used to investigate the relationship between the surgical approach and outcomes of interest. ResultsAmong the 664 patients included in the study, the distribution of surgical approaches was as follows: 351 (52.9%) underwent TME via the open approach, 159 (23.9%) via the robotic approach, and 154 (23.2%) via the laparoscopic approach. There were no significant differences in baseline demographics among the three cohorts. The laparoscopic cohort had fewer patients with low rectal cancer (<6 cm from the anal verge) than the robotic and open cohorts (Lap 28.6% versus Rob 59.1% versus Open 45.6%, P = 0.015). Patients who underwent Rob and Lap TME had lower intraoperative blood loss compared with the Open approach (Rob 200 mL [Q1, Q3: 100.0, 300.0] versus Lap 150 mL [Q1, Q3: 75.0, 250.0] versus Open 300 mL [Q1, Q3: 150.0, 600.0], P < 0.001). There was no difference in the operative time (Rob 243 min [Q1, Q3: 203.8, 300.2] versus Lap 241 min [Q1, Q3: 186, 336] versus Open 226 min [Q1, Q3: 178, 315.8], P = 0.309) between the three approaches. Postoperative length of stay was shorter with robotic and laparoscopic approach compared to open approach (Rob 5.0 d [Q1, Q3: 4, 8.2] versus Lap 5 d [Q1, Q3: 4, 8] versus Open 7.0 d [Q1, Q3: 5, 9], P < 0.001). There was no statistically significant difference in the quality of TME between the robotic, laparoscopic, and open approaches (79.2%, 64.9%, and 64.7%, respectively; P = 0.46). The margin positivity rate, a composite of circumferential margin and distal margin, was higher with the robotic and open approaches than with the laparoscopic approach (Rob 8.2% versus Open 6.6% versus Lap 1.9%, P = 0.17), Rob versus Lap (odds ratio 0.21; 95% confidence interval 0.05, 0.83) and Rob versus Open (odds ratio 0.5; 95% confidence interval 0.22, 1.12). There was no difference in long-term survival, including overall survival and recurrence-free survival, between patients who underwent robotic, laparoscopic, or open TME (Figure 1). ConclusionsIn patients undergoing surgery with curative intent for rectal cancer, we did not observe a difference in the quality of TME between the robotic, laparoscopic, or open approaches. Robotic and open TME compared to laparoscopic TME were associated with higher margin positivity rates in our study. This was likely due to the higher percentage of low rectal cancers in the robotic and open cohorts. We also reported no significant differences in overall survival and recurrence-free survival between the aforementioned surgical techniques.

Recipient blood group does not affect hepatocellular carcinoma recurrence after living donor liver transplantation in Korea.

This study assessed whether or not the ABO blood type affects the incidence of HCC recurrence after living donor liver transplantation (LDLT). This retrospective observational study included 856 patients with hepatocellular carcinoma (HCC) who underwent LDLT between January 2006 and December 2016 at the Asan Medical Center. This study included 324 patients (37.9%) with blood type A, 215 (25.1%) with blood type B, 210 (24.5%) with blood type O, and 107 (12.5%) with blood type AB. ABO-incompatible LT was performed in 136 (15.9%) patients. The independent risk factors for the disease-free survival (DFS) were maximal tumor diameter, microvascular invasion, and Milan criteria. The only independent risk factor for the overall survival (OS) was microvascular invasion. The ABO blood group did not affect the DFS (P = 0.978) or OS (P = 0.261). The DFS according to the ABO blood group did not differ significantly between the ABO-compatible (p = 0.701) and ABO-incompatible LDLT recipients (p = 0.147). The DFS according to the ABO blood group did not differ significantly between patients within the Milan criteria (p = 0.934) and beyond the Milan criteria (p = 0.525). The DFS did not differ significantly between recipients with and without type A blood (p = 0.941). This study demonstrated that the ABO blood group system had no prognostic impact on the oncological outcomes of patients undergoing LT for HCC.

Impact of Cytoreductive Nephrectomy in the Management of Metastatic Renal Cell Carcinoma: A Multicenter Retrospective Study.

In this study, we aimed to determine the utility of cytoreductive nephrectomy (CN) in real-world clinical practice and investigate whether CN contributes to improved oncological outcomes in patients with metastatic renal cell carcinoma (mRCC). This retrospective multicenter cohort study enrolled patients with mRCC who received systemic therapy at six institutions between May 2005 and May 2023. The patients were divided into those who did not undergo CN (Group I) and those who underwent CN (Group II). The primary endpoints were oncological outcomes, including cancer-specific survival (CSS) and progression-free survival (PFS). Altogether, 137 patients with mRCC were included in this study. The median CSS was 14 months in Group I and 32 months in Group II (p < 0.001). Additionally, the median PFS in Groups I and II was 5 and 13 months, respectively (p = 0.006). A multivariate analysis showed that CN was an independent prognostic factor for CSS and PFS. Hence, CN is a potential treatment modality that can improve oncological outcomes in patients with mRCC.

Beyond scalpels: A meta-analysis of robotic and laparoscopic gastrectomy in long-term oncological outcomes in gastric cancer.

e16125 Background: Gastric cancer persists as a substantial worldwide health concern, serving as a prominent contributor to both the incidence and fatalities associated with cancer. In this context, robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) in patients with gastric cancer is a subject of extensive scientific investigation, reflecting the ongoing evolution of minimally invasive surgical techniques. RG has been posited as a potentially advantageous alternative to LG, as it is associated with improved precision and maneuverability, particularly in complex anatomical scenarios. Conversely, LG, with its established history and widespread adoption, is characterized by a shorter learning curve and potential cost advantages. Scientific literature suggests comparable outcomes between the two techniques, while others report divergent results in terms of operative time, blood loss, and complication rates. However, the impact of both techniques in long-term oncological outcomes remains unclear. Therefore, we aimed to perform a systematic review and meta-analysis for RG and LG for oncological outcomes in patients with gastric cancer. Methods: A systematic search was performed in PubMed, Cochrane and Embase in January 2024 for randomized controlled trials or observational studies comparing RG with LG in patients with gastric cancer. Risk ratios (RR) for binary outcomes with a 95% confidence interval (CI) were pooled and a p-value &lt; 0.05 was considered statistically significant. Rayyan and Review Manager 5.3 software were selected, respectively, to manage the reported references and perform the statistical analysis of this study. Results: A total of 3727 results were screened, of which 13 were included in the meta-analysis, totalizing 25428 patients. There were no differences between RG and LG for 3-year overall survival (RR 1.03, 95% CI 1.00 - 1.06, I2 = 50%, p = 0.06), 3-year disease free survival (RR 1.01, 95% CI 0.95 - 1.06, I2 = 45%, p = 0.82), recurrence free survival (RR 0.51, 95% CI 0.22 - 1.20, I2 = 100%, p = 0.12), 5-year disease free survival (RR 1.02, 95% CI 0.99 - 1.05, I2 = 0%, p = 0.23), and ≥ 3-year overall survival (RR 1.02, 95% CI 1.00 - 1.05, I2 = 38%, p = 0.03). Conclusions: These findings from this comprehensive meta-analysis reveal a lack of discernible disparity between RG and LG in terms of oncological outcomes. The collective evidence suggests comparable results, emphasizing the need for continued research to refine our understanding and guide clinical decision-making in the pursuit of optimized patient care. These results contribute to the ongoing dialogue surrounding optimal treatment strategies for the assessed condition.

Prognostic Impact of Intraoperative Rupture in Early-Stage Epithelial Ovarian Cancer: An Ancillary Study of GORILLA-3002

ObjectiveTo evaluate whether intraoperative rupture affects oncological outcomes in patients with early-stage epithelial ovarian cancer (EOC). MethodsA multicenter retrospective study was conducted on patients with early-stage EOC based on surgical and final pathological reports between 2007 and 2021. Oncologic outcomes were compared between the unruptured group (International Federation of Gynaecology and Obstetrics [FIGO] stage IA/IB) and ruptured group (FIGO stage IC1). The primary endpoint was progression-free survival (PFS). Propensity score matching (PSM) was performed to adjust for the imbalance in prognostic factors between the groups. ResultsOverall, 197 (58.3%) patients comprised the unruptured group (FIGO stage IA/IB), and 141 (41.7%) were in the intraoperatively ruptured group (FIGO stage IC1). No significant difference in the 5-year PFS was observed between the two groups before PSM (92.65% vs. 92.80%, P = 0.93). After PSM, the 5-year PFS showed a noticeable decrease in the ruptured group compared to the unruptured group, although this difference showed borderline statistical significance (96.90% vs. 89.82%, P = 0.061). This trend was particularly discernible in cases with aggressive tumor characteristics; intraoperative rupture remained an independent prognostic factor for shorter PFS in patients with high-grade histology (adjusted hazard ratio = 14.4, 95% confidence interval = 2.8–74.1). ConclusionsAlthough not statistically significant, intraoperative rupture may negatively affect PFS in these patients after PSM. Therefore, rupture during surgery should be avoided as it can cause upstaging and unnecessary chemotherapy.

Effects of Adjuvant Chemotherapy on Oncologic Outcomes in Patients With Stage ⅡA Rectal Cancer Above the Peritoneal Reflection Who Did Not Undergo Preoperative Chemoradiotherapy

PurposeThis study aimed to evaluate the effects of adjuvant chemotherapy (AC) on oncologic outcomes for patients with stage IIA upper rectal cancer and to investigate whether AC is associated with improved survival outcomes. MethodsThis retrospective study comprised 432 patients with rectal cancer above the peritoneal reflection who had undergone curative resection without preoperative chemoradiotherapy between 2008 and 2016. This study cohort was divided according to whether AC was received (AC group) or not (no-AC group). Risk factors included obstruction, perforation, poorly-differentiated tumor, lympho-vascular invasion, perineural invasion, resection margin involvement, and < 12 lymph nodes harvested. ResultsAmong the 432 patients, 279 (64.6%) had received AC. The AC group had significantly higher 5-year overall survival (OS) rates than those of the no-AC group (93.2% vs. 84.6%, P = .001). Among patients with ≥ 1 risk factors, the AC group (n = 123) had significantly higher rates of 5-year recurrence-free survival (RFS) (81.6% vs. 64.1%, P = .01) and 5-year OS (88.8% vs. 69.0%, P = .001) than those of the no-AC group (n = 59). No significant difference in survival outcomes was observed between the 2 groups in patients aged > 65 years. ConclusionAC was significantly associated with better 5-year RFS and 5-year OS rates in patients with stage IIA rectal cancer above peritoneal reflection who did not receive preoperative chemoradiotherapy, especially in those with ≥ 1 risk factors.

Preoperative and postoperative platelet-lymphocyte ratio as a prognostic marker for patients with soft tissue sarcoma treated with curative resection.

e23568 Background: In cancer development and progression, systemic inflammation has been implicated. Inflammatory markers have been identified as prognostic indicators in numerous malignancies. In this study, we explored the prognostic relevance of initial and postoperative systemic inflammatory markers (neutrophil -lymphocyte ratio, platelet -lymphocyte ratio) on relapse-free survival (RFS) and overall survival (OS) in patients with soft -tissue sarcoma (STS) who underwent curative resection. Methods: We included a total of 89 patients with STS who underwent extensive and radical resection at the Kyungpook National University Chilgok Hospital (Daegu, Korea,) between 2004 and 2018. Kaplan-Meier curves and RFS and OS were calculated using multivariate Cox proportional models. Results: The median age of the patients was 55 years (range 27 - 86) and the ratio of male-to-female ratio was approximately 1:1. A total of 67 (75.3%) patients demonstrated a high initial neutrophil-lymphocyte ratio(NLR) (≥4.1) and 65 (75.3%) showed a high initial platelet-lymphocyte ratio(PLR) (≥231). After curative resection, the number of patients with high NLR and PLR was 16(18.0%) and 17 (29.3%). In both the NLR and PLR groups, including the postoperative NLR and postoperative PLR subgroups, no significant differences were observed in terms of age, sex, histologic type, tumor site, tumor size, tumor depth, or American Joint Committee on Cancer staging when stratified into high and low subgroups. In the univariate and multivariate analyses, an elevated initial PLR ratio was significantly associated with a decreased RFS (hazard ratio[HR]: 2.120; 95% confidence interval[CI]: 1.021 - 4.883, p = 0.017) and OS (HR: 5.073; 95% CI: 1.731 - 14.87, p = 0.003). Patients with a high PLR (PLR &gt; 231) had a median RFS of 24 months, whereas those with a low PLR (PLR ≤231) had a median RFS of 96 months. The median OS was 50 and 298 months for the high PLR and low PLR groups, respectively. Furthermore, a high postoperative PLR ratio was significantly associated with a decreased RFS (HR: 3.921; 95% CI: 1.738 - 8.845, p = 0.001) and OS (HR: 5.702; 95% CI: 1.099 -29.576, p = 0.038). Conclusions: The present results suggest that the preoperative and postoperative PLR ratio can be used as a cost- effective prognostic marker for oncologic outcomes in patients with STS who underwent surgery.

Association of Pringle maneuver with postoperative recurrence and survival following hepatectomy for hepatocellular carcinoma: a multicenter propensity score and competing-risks regression analysis.

The application of Pringle maneuver (PM) during hepatectomy reduces intraoperative blood loss and the need for perioperative transfusion, but its effect on long-term recurrence and survival for patients with hepatocellular carcinoma (HCC) remains controversial. We sought to determine the association between the application of PM and post-hepatectomy oncologic outcomes for patients with HCC. Patients who underwent curative hepatectomy for HCC at 9 Chinese hospitals from January 2010 to December 2018 were identified. Using two propensity score methods [propensity score matching (PSM) and inverse probability of treatment weight (IPTW)], cumulative recurrence rate and cancer-specific mortality (CSM) were compared between the patients in the PM and non-PM groups. Multivariate competing-risks regression models were performed to adjust for the effect of non-cancer-specific mortality and other prognostic risk factors. Of the 2,798 included patients, 2,404 and 394 did and did not adopt PM (the PM and non-PM groups), respectively. The rates of intraoperative blood transfusion, postoperative 30-day mortality and morbidity were comparable between the two groups (all P>0.05). In the PSM cohort by the 1:3 ratio, compared to 382 patients in the non-PM group, 1,146 patients in the PM group also had the higher cumulative 5-year recurrence rate and CSM (63.9% and 39.1% vs. 55.3% and 31.6%, both P<0.05). Similar results were also yielded in the entire cohort and the IPTW cohort. Multivariate competing-risks regression analyses demonstrated that no application of the PM was independently associated with lower recurrence rate and CSM based on various analytical cohorts [hazard ratio (HR), 0.82 and 0.77 in the adjusted entire cohort, HR 0.80 and 0.73 in the PSM cohort, and HR 0.80 and 0.76 in the IPTW cohort, respectively]. The findings suggested that no application of PM during hepatectomy for patients with HCC reduced the risk of postoperative recurrence and cancer-specific death by approximately 20-25%.

Long-Term Outcomes in Patients Using Protocol-Directed Active Surveillance for Prostate Cancer

Outcomes from protocol-directed active surveillance for favorable-risk prostate cancers are needed to support decision-making. To characterize the long-term oncological outcomes of patients receiving active surveillance in a multicenter, protocol-directed cohort. The Canary Prostate Active Surveillance Study (PASS) is a prospective cohort study initiated in 2008. A cohort of 2155 men with favorable-risk prostate cancer and no prior treatment were enrolled at 10 North American centers through August 2022. Active surveillance for prostate cancer. Cumulative incidence of biopsy grade reclassification, treatment, metastasis, prostate cancer mortality, overall mortality, and recurrence after treatment in patients treated after the first or subsequent surveillance biopsies. Among 2155 patients with localized prostate cancer, the median follow-up was 7.2 years, median age was 63 years, 83% were White, 7% were Black, 90% were diagnosed with grade group 1 cancer, and median prostate-specific antigen (PSA) was 5.2 ng/mL. Ten years after diagnosis, the incidence of biopsy grade reclassification and treatment were 43% (95% CI, 40%-45%) and 49% (95% CI, 47%-52%), respectively. There were 425 and 396 patients treated after confirmatory or subsequent surveillance biopsies (median of 1.5 and 4.6 years after diagnosis, respectively) and the 5-year rates of recurrence were 11% (95% CI, 7%-15%) and 8% (95% CI, 5%-11%), respectively. Progression to metastatic cancer occurred in 21 participants and there were 3 prostate cancer-related deaths. The estimated rates of metastasis or prostate cancer-specific mortality at 10 years after diagnosis were 1.4% (95% CI, 0.7%-2%) and 0.1% (95% CI, 0%-0.4%), respectively; overall mortality in the same time period was 5.1% (95% CI, 3.8%-6.4%). In this study, 10 years after diagnosis, 49% of men remained free of progression or treatment, less than 2% developed metastatic disease, and less than 1% died of their disease. Later progression and treatment during surveillance were not associated with worse outcomes. These results demonstrate active surveillance as an effective management strategy for patients diagnosed with favorable-risk prostate cancer.

To investigate the impact of a prior cervical excisional procedure on the oncologic outcomes of patients with apparent early-stage cervical carcinoma undergoing radical hysterectomy. The National Cancer Database (2004-2015) was accessed, and patients with FIGO 2009 stage IB1 cervical cancer who had a radical hysterectomy with at least 10 lymph nodes (LNs) removed and a known surgical approach were identified. Patients who did and did not undergo a prior cervical excisional procedure (within 3 months of hysterectomy) were selected for further analysis. Overall survival (OS) was evaluated following the generation of Kaplan-Meier curves and compared with the log-rank test. A Cox model was constructed to control a priori-selected confounders. A total of 3159 patients were identified; 37.1% (n = 1171) had a prior excisional procedure. These patients had lower rates of lymphovascular invasion (29.2% vs. 34.9%, p = 0.014), positive LNs (6.7% vs. 12.7%, p < 0.001), and a tumor size >2 cm (25.7% vs. 56%, p < 0.001). Following stratification by tumor size, the performance of an excisional procedure prior to radical hysterectomy was associated with better OS even after controlling for confounders (aHR: 0.45, 95% CI: 0.30, 0.66). The rate of minimally invasive surgery was higher among patients who had a prior excisional procedure (61.5% vs. 53.2%, p < 0.001). For these patients, performance of minimally invasive radical hysterectomy was not associated with worse OS (aHR: 1.37, 95% CI: 0.66, 2.82). For patients undergoing radical hysterectomy, preoperative cervical excision may be associated with a survival benefit. For patients who had a prior excisional procedure, minimally invasive radical hysterectomy was not associated with worse overall survival.
