Circulating Chromogranin A is associated with disease extent, progression and recurrence in patients with non-functioning pancreatic neuroendocrine tumor (NF-PNET).

Objectives: Non-functioning Pancreatic Neuroendocrine Tumors (NF-PNET) are rare tumors with heterogeneous biology. Radiology and serum biomarkers are used for post-resection surveillance; however, no universally established protocol exists. Serum Chromogranin A (CgA) concentration is elevated in NF-PNET, and generally correlates with burden of disease; many CgA studies include mixed gastrointestinal and pancreatic populations.

The use of nephron-sparing intervention does not appear to be compromised after a period of active surveillance for patients with cT1 renal masses.

Introduction And Objective: It remains unknown whether the use of nephron sparing intervention (NSI) is impacted with delayed intervention after a period of active surveillance (AS) compared with immediate intervention for patients with clinically localized renal masses ≤7cm (cT1RMs). We hypothesized that the proportion of patients undergoing NSI is similar among patients undergoing immediate and delayed intervention for cT1RMs.

Methods: We retrospective reviewed the prospectively maintained Michigan Urological Surgery Improvement Collaborative (MUSIC) registry for patients undergoing intervention for cT1RMs from 05/2017 to 09/2023.

Impact of Gene Expression Classifier Testing on Adjuvant Treatment Following Radical Prostatectomy: The G-MINOR Prospective Randomized Cluster-crossover Trial.

Background And Objective: Decipher is a tissue-based genomic classifier (GC) developed and validated in the post-radical prostatectomy (RP) setting as a predictor of metastasis. We conducted a prospective randomized controlled cluster-crossover trial assessing the use of Decipher to determine its impact on adjuvant treatment after RP.

Methods: Eligible patients had undergone RP within 9 mo of enrollment, had pT3-4 disease and/or positive surgical margins, and prostate-specific antigen <0.

Staging accuracy in patients with clinical T2N0 gastric cancer: Implications for treatment sequencing.

Background: Patients with clinical T2N0 (cT2N0) gastric adenocarcinoma are recommended to undergo either perioperative chemotherapy or upfront resection. If T2N0 disease is pathologically confirmed, patients may be observed without chemotherapy. These guidelines create the possibility of both systemic therapy overuse and underuse depending on clinical staging accuracy.

Surgeon Skill and Perioperative Outcomes in Robot-Assisted Partial Nephrectomy.

Importance: Technical skill in complex surgical procedures may affect clinical outcomes, and there is growing interest in understanding the clinical implications of surgeon proficiency levels.

Objectives: To determine whether surgeon scores representing technical skills of robot-assisted kidney surgery are associated with patient outcomes.

Design, Setting, And Participants: This quality improvement study included 10 urological surgeons participating in a surgical collaborative in Michigan from July 2021 to September 2022.
