Unlabelled: The standard operation for colon cancer resection should follow certain principles to ensure appropriate oncologic resection, such as retrieving 12 or more nodes with the specimen and adequate surgical margins. Although these principles are well documented, there is little evidence regarding the association of race and the attainment of an adequate oncologic resection.
Methods: The authors performed a retrospective cohort study of all cases of resectable colon adenocarcinoma who underwent surgical resection in the National Cancer Database between 2004 and 2018. The postoperative lymph node count and margins were grouped as 'principles of oncologic surgical resection'. A multivariate logistic regression analysis was performed to assess race and other demographic variables as independent factors influencing the attainment of the principles of oncologic resection.
Results: A total of 456 746 cases were included. From this cohort, 377 344 (82.6%) achieved an adequate oncologic resection and 79 402 (17.4%) did not. On logistic regression, African American and Native American patients were less likely to attain an adequate oncologic resection. Similarly, patients with an elevated Charlson-Deyo score (2 or above), stage I cancer, and patients who underwent extended resection were less likely to achieve adequate oncologic resection. Resections performed in metropolitan areas, patients with private insurance, high-income quartiles, and patients diagnosed in more recent years were more likely to achieve adequate oncologic resection.
Conclusions: There are significant racial disparities regarding the attainment of the principles of oncologic resection in colon cancer, which could be explained by unconscious biases, social discrepancies, and inadequate healthcare access. Early introduction and conscientization of unconscious biases are required in surgical training.

Randomised controlled feasibility trial of retroperitoneal vs transperitoneal robot-assisted partial nephrectomy: the ROPARN study.
BJU Int

Department of Urology, St. Josef Medical Center, University of Regensburg, Regensburg, Germany.
Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).
Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.

Background: Randomized studies have demonstrated that laparoscopic abdominoperineal resection is not inferior to open abdominoperineal resection for rectal cancer.
Aims: Evaluate the immediate and extended results of laparoscopic abdominoperineal resection versus open abdominoperineal resection for rectal cancer.
Methods: From January 2006 to December 2017, a total of 1852 patients with rectal cancer who had undergone abdominoperineal resection were enrolled in this investigation.

Optimal management of T1 colorectal cancer (CRC) remains controversial. This study compared the long-term outcomes of endoscopic resection with additional surgical resection (ER + ASR) versus primary surgical resection (PS) in patients with T1 CRC and identified risk factors for lymph node metastasis (LNM). This retrospective cohort study included 373 patients with T1 CRC who underwent ER + ASR or PS between January 2010 and December 2020 at a tertiary center in Taiwan.

Background: An increasingly large proportion of patients undergoing curative surgery for lung cancer, are octogenarians. We evaluated our short and long-term survival and adverse outcomes after oncological lung resections.
Methods: Octogenarians undergoing anatomical resection for confirmed or suspected lung cancer at a single-centre between January 2016 and December 2021 were included.
