Background Multiple socioeconomic and clinical factors have been implicated in the health disparities that exist amongst vulnerable populations with colorectal cancer. Efforts have been directed toward addressing these factors to improve outcomes. We evaluate the impact of primary care physicians (PCP) on the surgical presentation and outcomes of colorectal cancer at a safety-net hospital. Methods A retrospective chart review of 331 patients diagnosed with colorectal adenocarcinoma between 2014 and 2020 at a single-institution urban county medical center. Results The cohort was predominantly male (59%) and Hispanic (52.1%). Thirty-two percent of patients had a PCP at time of diagnosis. Patients with PCPs compared to those without PCPs had significantly lower rates of acute presentation (perforation or obstruction) (17.0 vs 38.1%, P < .001), higher rates of surgical resection (83.0 vs 70.7%, P = .016), and were less likely to have metastatic disease at presentation (20.4 vs 33.5%, P = .02). Overall, having a PCP also improved probability of survival (HR 1.36, P < .04). Conclusion Having a PCP at the time of colorectal cancer diagnosis is associated with improved outcomes in a safety-net population, with significant differences in surgical presentation and resection.

Introduction The optimal management of major stump complications (operative infection or dehiscence) following below-knee-amputation (BKA) is unknown. We evaluated a novel operative strategy to aggressively treat major stump complications hypothesizing it would improve our rate of BKA salvage. Methods Retrospective review of patients requiring operative intervention for BKA stump complications between 2015 and 2021. A novel strategy employing staged operative debridement for source control, negative pressure wound therapy, and reformalization was compared to standard care (less structured operative source control or above knee amputation). Results 32 patients were studied, 29 of which were male (90.6%) with an average age of 56.1 ± 9.6 y. 30 (93.8%) had diabetes and 11 (34.4%) peripheral arterial disease (PAD). The novel strategy was used in 13 patients and 19 had standard care. Novel strategy patients had higher BKA salvage rates, 100% vs 73.7% ( P = .064), and postoperative ambulatory status, 84.6% vs 57.9% ( P = .141). Importantly, none of the patients undergoing the novel therapy had PAD, while all progressing to above-knee amputation (AKA) did. To better assess the efficacy of the novel technique, patients progressing to AKA were excluded. Patients undergoing novel therapy who had their BKA level salvaged (n = 13) were compared to usual care (n = 14). The novel therapy’s time to prosthetic referral was 72.8 ± 53.7 days vs 247 ± 121.6 days ( P < .001), but they did undergo more operations (4.3 ± 2.0 vs 1.9 ± 1.1, P < .001). Conclusion Utilization of a novel operative strategy for BKA stump complications is effective in salvaging BKAs, particularly for patients without PAD.
