Background: Adrenocortical carcinoma (ACC) is a rare tumor and the role of lymph node dissection remains ill-defined. This study evaluates the effect of no dal examination on prognosis and survival in patients undergoing curative-intent resection of ACC. Methods: The National Cancer Database (2004-2015) was queried for patients undergoing margin-negative resection for ACC. Patients with distant metastases, neoadjuvant therapy, multivisceral resection and T4 tumors were excluded. Results: Among 897 patients, 147 (16.4%) had lymph nodes examined. Factors associated with lymph node examination included increasing tumor size (P < .001), extra-adrenal extension (P < .001), open operation (P < .001), and resection at an academic facility (P = .003). Lymph node metastasis was significantly associated with extra-adrenal tumor extension (P = .04). Lymph node harvest, regardless of the number of nodes examined, was not associated with a survival benefit. Median overall survival was incrementally worse with increasing number of positive lymph nodes (88.2 months for N0, 34.9 months for 1-3 positive nodes, and 15.6 months for ≥4 positive nodes, P < .001). Conclusions: Lymph node harvest and lymph node metastasis were associated with more advanced tumors. Although nodal harvest did not offer a survival advantage, stratifying the nodal staging classification may provide important prognostic information.
Background: Socioeconomic disparities in gastric cancer have been associated with differences in care and inferior outcomes. We evaluated the presentation, treatment, and survival for patients with gastric cancer (GC) in a metropolitan setting with a large African American population.Methods: Retrospective cohort analysis of patients with GC (2003-2018) across a multi-hospital system was performed. Associations between socioeconomic and clinicopathologic data with the presentation, treatment, and survival were examined.Results: Of 359 patients, 255 (71%) were African American and 104 (29%) Caucasian.African Americans were more likely to present at a younger age (64.0 vs 72.5, P < .001), have state-sponsored or no insurance (19.7% vs 6.9%, P = .02), reside within the lowest 2 quintiles for median income (67.4% vs 32.7%, P < .001), and have higher rates of Helicobacter pylori (14.9% vs 4.8%, P = .02). Receipt of multi-modality therapy was not impacted by race or insurance status. On multivariable analysis, only AJCC T class (HR 1.68) and node positivity (HR 2.43) remained significant predictors of disease-specific survival.Conclusion: Despite socioeconomic disparities, African Americans, and Caucasians with GC had similar treatment and outcomes. African Americans presented at a younger age with higher rates of H. pylori positivity, warranting further investigation into differences in risk factors and tumor biology.
Background: Secondary adrenal insufficiency (AI) can develop following unilateral adrenalectomy (UA) foradrenal-dependent hypercortisolism (HC) and has been reported after UA for primaryaldosteronism (PA). An institutional study previously demonstrated that cosyntropin stimulationtesting on postoperative day 1 (POD1-CST) successfully identified patients who requiredglucocorticoid replacement (GR) following UA; 50% of HC patients required GR and no PApatients required GR. The aim of this study was to reevaluate the need for GR following UA forpatients with HC and PA in a larger cohort of patients. Methods We reviewed 108 patients from a prospectively maintained adrenal database who underwent UAfor HC (n=74), PA (n=22), and concurrent HC/PA (n=12) from 9/2014-10/2020. PA patientswithout preoperative evaluation for HC were excluded. Patients with 1mg dexamethasonesuppression test (DST) cortisol >1.8 (µg/dL) were defined as having mild HC, with ³5 defined asovert Cushing’s Syndrome (CS). All patients underwent our institutional POD1-CST protocoland GR was initiated for patients with basal cortisol £5 or stimulated cortisol £14 (<18 prior to4/2017). Results: Overall, 51 (47%) patients had an abnormal POD1-CST and were discharged on GR (44 HC, 1PA, and 6 HC/PA). Two (2%) patients with CS had a normal POD1-CST but developed AIrequiring GR at 8 and 12 weeks post UA. Of the 74 patients with HC, 44 (59%) had an abnormalPOD1-CST and were discharged on GR, including 19/28 (68%) with CS and 25/46 (54%) withmild HC. Preoperative DST cortisol was higher in HC patients who required GR compared topatients with a normal POD1-CST (4.1 vs 3.6; p=0.007). Median cortisol levels for HC patientswith an abnormal POD1-CST vs those with a normal test were: basal: 3.8 vs 15.6 (p=0.027); 30-minute: 10.1 vs 20.1 (p=0.403); and 60-minute 11.4 vs 22.2 (p=0.260). Of the 22 PA patients, 19(86%) had a normal POD1-CST. Median cortisol levels for PA patients with an abnormal POD1-CST vs those with a normal test were: basal: 0.4 vs 12.1; 30-minute: 8.8 vs 24.6; and 60-minute:12.2 vs 28.9. Of the 3 (14%) PA patients with an abnormal POD1-CST, 1 was dischargedwith GR and began tapering after 2 weeks; the other 2 did not require GR and did not developAI. Of the 12 patients with combined PA/HC, 6 (50%) were discharged on GR based on POD1-CST. GR was required by 30 (59%) patients for <3 months and 82% for <12 months; 7/9 whorequired GR >12 months had CS. Conclusions: Using a standard protocol for POD1-CST in patients who underwent unilateral adrenalectomyfor HC, PA, or combined PA/HC, this study demonstrated that routine GR is not required in 32%of patients with CS and 46% of patients with mild HC. POD1-CST safely identifies patients whowill require GR with no immediate concern for adrenal insufficiency. These data also suggestthat routine evaluation for AI in postoperative PA patients is not needed if cortisol excess hasbeen excluded preoperatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
