Second primary malignancies in women with breast cancer.

BACKGROUND: Increased screening and treatment advancements have resulted in improved survival rates in women with breast cancer (BC). However, recent data suggests these women have elevated risk of developing a second primary malignancy (SPM) compared to the general population. Limited data exists on factors associated with BC patients developing a SPM. METHOD: A retrospective review of a prospective single institution database (1990-2016) identified 782 patients with a history of BC. One hundred and ninety-four BC patients developed a SPM. Clinicopathologic and treatment characteristics were analyzed. RESULTS: Of the 194 patients (24.8%) who developed a SPM, 56 (28.9%) BC patients were <50 years old (range: 24-87 years). Two-thirds (64.9%) had at least one first or second degree relative with a malignancy (no relatives-35.1%; ≥1 relative-62.9%). Most patients had invasive ductal carcinoma (n = 117, 60.3%) or ductal carcinoma in situ (n = 39, 20.1%). Twenty-two patients (11.3%) had pathogenic genetic mutations. Mean time to developing a SPM was 8.9 years (range: 4 months-50 years). Eighty (47.6%) patients received chemotherapy with 91 (54.5%) completing radiation. The most common SPMs were breast (22%), melanoma (17.8%), gynecologic (14.1%), colorectal (12.6%), hematologic (8.9%), and sarcoma (6.5%). Most breast tumors were estrogen receptor (ER) (n = 99, 78.0%) or progesterone receptor (PR) positive (n = 87, 73.1%) but not HER2-neu positive (n = 13, 14.0%). CONCLUSION: Most BC patients who developed a SPM had ER/PR positive tumors and a family history of malignancy, with most <50 years old. Although chemotherapy and radiation increase cancer risk, there were an equal number of patients with SPMs who did or did not receive either treatment. Most SPMs were breast, soft tissue, gynecologic, hematologic, or colorectal. BC patients should be followed closely given an elevated propensity for developing SPMs.

Enhancing Lymph Node Yield in Gastric Cancer Resection: Impact of Back Table Dissection on Number of Lymph Node Examined.

INTRODUCTION: During gastric cancer resection, back table dissection (BTD) involves examination and separation of lymph node (LN) packets from the surgical specimen based on LN stations, which are sent to pathology as separately labeled specimens. With potential impact on clinical outcomes, we aimed to explore how BTD affects number of LNs examined. METHODS: A retrospective review of a gastric cancer database was performed, including all cases of gastrectomy with D2 lymphadenectomy from January 2009 to March 2022. Back table dissection and conventional groups were compared using Mann-Whitney U and Fisher's exact tests. Multiple linear regression modeling was used to identify potential predictors of number of LN examined. RESULTS: A total of 174 patients were identified: 39 (22%) BTD and 135 (78%) conventional. More patients in the BTD group underwent neoadjuvant chemotherapy (62% vs 29%, P < .05). Compared to the conventional group, the BTD group had a greater number of LNs examined (42 [26-59] vs 21[15-33], median [IQR], P < .001), lower LN positivity ratio (.01 vs .07, P = .013), and greater number of LNs in patients with BMI >35 (32.5[27.5-39] vs 22[13-27], P = .041). A multiple linear regression model controlling for age, BMI, preoperative N stage, neoadjuvant chemotherapy, surgeon experience, and operative approach identified BTD as a significant positive predictor of number of LN examined (ß = 19.7, P = .001). CONCLUSION: Back table dissection resulted in improved LN yield during gastric cancer resection. As a simple technical addition, BTD helps enhance pathology examination and improve surgeon awareness, which may ultimately translate to improve oncologic outcomes.

Impact of primary tumor resection in the management of metastatic well-differentiated neuroendocrine tumors of the small bowel and pancreas.

Patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET) often present with advanced disease. Primary tumor resection (PTR) in the setting of unresectable metastatic disease is controversial. Most studies evaluating the impact of PTR on overall survival (OS) have been performed using large population-based databases, with limited treatment related data. This study aims to determine whether PTR improves OS and progression-free survival (PFS) in patients with metastatic well-differentiated GEP-NET. This is a retrospective single-institution study of patients with metastatic well-differentiated GEP-NET between 1978 and 2021. The primary outcome was OS. The secondary outcome was PFS. Chi-squared tests and Cox regression were used to perform univariate and multivariate analyses (MVA). OS and PFS were estimated using the Kaplan-Meier method and log-rank test. Between 1978 and 2021, 505 patients presented with metastatic NET, 151 of whom had well-differentiated GEP-NET. PTR was performed in 31 PNET and 77 SBNET patients. PTR was associated with improved median OS for PNET (136 vs. 61 months, p = .003) and SBNET (not reached vs. 79 months, p<.001). On MVA, only higher grade (HR 3.70, 95%CI 1.49-9.17) and PTR (HR 0.21, 95%CI 0.08-0.53) influenced OS. PTR resulted in longer median PFS for patients with SBNET (46 vs. 28 months, p = .03) and a trend toward longer median PFS for patients with PNET (20 vs. 13 months, p = .07). In patients with metastatic well-differentiated GEP-NET, PTR is associated with improved OS and may be associated with improved PFS and should be considered in a multidisciplinary setting. Future prospective studies are needed to validate these findings.

Comparison of Clinical Breast Exam to Breast MRI Surveillance in Patients Following Nipple-Sparing Mastectomy.

BACKGROUND: Nipple sparing mastectomy (NSM) is increasingly being performed for patients with breast cancer. However, optimal postoperative surveillance has not been defined. METHODS: A prospectively maintained database identified patients with in-situ and invasive cancer who underwent NSM between 2007-2021. Clinical data on postoperative breast surveillance and interventions were collected. Patients who had MRI surveillance versus clinical breast exam (CBE) alone were compared with respect to tumor characteristics, recurrence, and survival. RESULTS: A total of 483 NSMs were performed on 399 patients. 255 (63.9%) patients had invasive ductal carcinoma, 31 (7.8%) invasive lobular carcinoma, 92 (23.1%) DCIS, 6 (1.5%) mixed ductal and lobular carcinoma, 9 (2.3%) others, and 6 (1.5%) unknown. Postoperatively, 265 (66.4%) patients were followed with CBE alone and 134 (33.6%) had surveillance MRIs. At a median follow-up of 33 months, 20 patients (5.0%) developed in-breast recurrence, 6 patients had (1.5%) an axillary recurrence, and 28 with (7.0%) distant recurrence. 14 (53.8%) LRR were detected in the CBE group and 12 (46.2%) were detected in the MRI group (P = .16). Overall survival (OS) was 99%, with no difference in OS between patients who had CBE alone versus MRI (P = .46). MRI was associated with higher biopsy rates compared to CBE alone (15.8% vs. 7.8%, P = .01). CONCLUSIONS: Compared to CBE alone, the use of screening MRI following NSM results in higher rate of biopsy and no difference in overall survival.

De-Implementation of Low-Value Care for Women 70 Years of Age or Older with Low-Risk Breast Cancer During the COVID-19 Pandemic.

BACKGROUND: Older women with early-stage estrogen receptor-positive (ER+) invasive breast cancer (IBC) are at risk for overtreatment. Guidelines allow for sentinel lymph node biopsy (SLNB) and radiotherapy omission after breast-conserving surgery (BCS) for women 70 years of age or older with T1, clinical node negativity (cN0), and ER+ IBC. The study objective was to evaluate radiotherapy and SLNB de-implementation in older women with low-risk IBC after the resource limitations of the COVID-19 pandemic. METHODS: An institutional database was analyzed to identify women 70 years of age or older who received BCS for IBC from 2012 to 2022. The patients were divided into two cohorts: (1) patients with low-risk IBC (pT1, cN0, and ER+/HER2-) who were eligible for radiotherapy and SLNB omission and (2) patients with high-risk IBC (pT2-T4, cN+, ER-, or HER2+) who were ineligible for therapy omission. Clinicopathologic variables in both cohorts were analyzed. RESULTS: The study enrolled 881 patients. For the patients with low-risk IBC, the annual rates of radiotherapy were stable from 2012 to 2019. However, radiotherapy utilization decreased significantly from 2020 to 2022 (58% in 2012 vs 36% in 2022; p = 0.04). In contrast, radiotherapy usage among the patients with high-risk IBC was stable from 2012 to 2022 (79% in 2012 vs 79% in 2022; p = 0.95). Among the patients with low-risk IBC, SLNB rates decreased from 86% in 2012 to 56% in 2022, but this trend predated those in 2020. The factors significantly associated with SLNB and receipt of radiotherapy among the patients with low-risk IBC were younger age, larger tumors, grade 3 disease, and involved nodal status (p < 0.01). CONCLUSION: This study demonstrated appropriate and sustained de-escalation of radiotherapy in older women with low-risk IBC after the COVID-19 pandemic.

Contemporary Cancer Program Practice Profile Report Compliance Rates for Gastric Cancer: A National Cancer Database Analysis.

BACKGROUND: The Commission on Cancer (CoC) established quality measures to be reported in National Cancer Database (NCDB) Quality Reporting Tools. Compliance is provided to accredited cancer programs as Cancer Program Practice Profile Reports (CP3R). At the time of this study, the quality metric for gastric cancer (GC) was removal and pathologic examination of 15 regional lymph nodes for resected GC (G15RLN). OBJECTIVE: This study evaluates national trends in quality metric compliance for GC based on CoC CP3R. METHODS: The National Cancer Database (NCDB) was queried from 2004-2017 to identify patients with stage I-III GC who met criteria for inclusion. National trends in compliance were compared. Overall survival (OS) was compared stage for stage. RESULTS: Overall, 42 997 patients with GC qualified. In 2017, 64.5% of patients met compliance with G15RLN compared to 31.4% in 2004. When comparing academic and non-academic institutions, compliance was met 67.0% vs 60.0% of the time in 2017 (P < .01) and 36% vs 30.6% of the time in 2004 (P < .01). On multivariate logistic regression, patients receiving care at academic institutions (OR 1.5, 95% CI 1.4-1.5) and who underwent surgery at institutions in the >75th percentile for case volume (OR 1.5, 95% CI 1.4-1.6) had higher odds of compliance. When stratified by stage, median OS was better across all stages when compliance was met. CONCLUSION: Compliance rates with GC quality measures have improved over time. Compliance with the G15RLN metric is associated with improved OS, stage for stage. Continued efforts to improve compliance rates across all institutions are critical.

Role of ROR2 in promoting gastric cancer metastasis by enhancing c-JUN-mediated MMP3 transcription.

Background: Receptor tyrosine kinase-like orphan receptor 2 (ROR2) is a transmembrane receptor that has a complex role in cancer, acting either to promote or inhibit tumor progression in different tumor types. The effect of ROR2 on gastric cancer is unclear. Methods: Immunohistochemistry was used to investigate the role of ROR2 in the prognosis of gastric cancer. Transwell assay and a BALB/c nude mice pulmonary metastasis model were used to ascertain the role of ROR2 in promoting metastasis in vitro and in vivo. A protein expression array, chromatin immunoprecipitation (ChIP) assay, and luciferase reporter assay were employed to search for the target genes of ROR2. Results: ROR2 was found to be upregulated in gastric cancer tissues, which was correlated with poor disease-free survival (DFS) and overall survival (OS) in gastric cancer patients. Moreover, ROR2 promoted gastric cancer cell migratory and invasive behaviors in vitro and metastasis in vivo. Further research showed that ROR2 promoted gastric cancer metastasis via upregulation of matrix metalloproteinase 3 (MMP3). Analyses of clinical data indicated that high expression of ROR2 was correlated with a high expression of MMP3. Further study showed that ROR2 activated c-JUN by translocating phosphorylated JNK1/2 into the nucleus, and c-JUN interacted directly with the MMP3 promoter, leading to enhanced MMP3 transcription. Conclusions: We report for the first time that ROR2 is upregulated in gastric cancer, promotes metastasis, and is associated with poor prognosis in gastric cancer. The findings suggest that ROR2 may be a promising prognostic predictor for gastric cancer. Silencing the JNK1/2-c-JUN pathway, thereby inhibiting MMP3 expression, may serve as a promising strategy to inhibit gastric cancer progression.

30-Day Postoperative Outcomes in Patients With Limited Mobility - A Propensity Score-Matched Comparative Analysis.

INTRODUCTION: There is limited data correlating preoperative mobility limitations with clinical outcomes in bariatric patients. This study uses propensity score matching (PSM) to compare 30-day outcomes between patients with preoperative limited mobility (LM) versus patients without (non-LM). METHODS: Using the 2016-2018 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, patients undergoing primary laparoscopic sleeve gastrectomy or gastric bypass were identified. Two cohorts were defined using preoperative LM status. To adjust for confounders, 1:1 PSM was performed using 25 preoperative characteristics, and balance was assessed with standardized mean difference. Preoperative patient demographics and postoperative 30-day outcomes were compared in both matched and unmatched cohorts. RESULTS: 453,146 patients were identified, of which 6942 (1.47%) were LM and 464,555 were non-LM. 1:1 PSM matched 6624 LM to 6624 non-LM patients with good balance for all covariates. LM had higher rates of unplanned intubation (0.4% vs 0.7%, P < .01), unplanned admission to ICU (1.4% vs 2.5%, P < .01), readmissions (4.1% vs 4.9%, P = .036), unplanned reoperation (1.5% vs 2.0%, P = .02), and 30-day mortality (0.2% vs 0.5%, P = .02). Complications including acute renal failure, intra/postoperative myocardial infarction, venous thrombosis, and pulmonary embolism were not significantly different between the matched groups. CONCLUSION: After adjusting for confounders, patients with preoperative limited mobility have higher rates of intubation, ICU admission, reoperation, readmission, and mortality. Prudent pre-operative candidate selection, counseling, and risk mitigation strategies are needed when a patient with limited mobility status is being considered for bariatric surgery.

Operative approach and case volume are associated with negative resection margins for adrenocortical carcinoma.

BACKGROUND: Surgical resection with negative margins is the treatment of choice for adrenocortical carcinoma (ACC). This study was undertaken to determine factors associated with negative resection margins. METHODS: National Cancer Database was queried from 2010 to 2016 to identify patients with AJCC/ENSAT Stage I-III ACC who underwent adrenalectomy. Patient, tumor, facility, and operative characteristics were compared by margin status (positive-PM or negative-NM) and operative approach (open-OA, laparoscopic-LA, or robotic-RA). Multivariable logistic regression was used to identify factors associated with PM. RESULTS: Eight hundred and eighty-one patients were identified, of which 18.4% had PM and 81.6% had NM. Patients with advanced pathologic T stage and pathologic N1 stage were more likely to have PM (vs. NM) (T3, 49.7% vs. 24.8%, p < 0.01; T4, 26.2% vs. 10.0%, p < 0.01; N1, 6.7% vs. 3.5%, p < 0.01). Patients undergoing OA (vs. LA and RA) were more likely to have advanced clinical T stage (T4, 16.6% vs. 5.7% vs. 7.8%, p < 0.01) and larger tumors (> 6 cm, 84.6% vs. 64.1% vs. 62.3%, p < 0.01). High-volume centers (≥ 5 cases) were more likely to utilize OA. Patients undergoing LA (vs. RA) were more likely to require conversion to open (20.3% vs. 7.8%, p = 0.011). On multivariable analysis, factors associated with higher odds of PM included T3 disease (OR 7.02, 95% CI 2.66-18.55), T4 disease (OR 10.22, 95% CI 3.66-28.53), and LA (OR 1.99, 95% CI 1.28-3.09). High-volume centers were associated with lower odds of PM (OR 0.67, 95% CI 0.45-0.98). There was no significant difference in margin status between OA and RA (OR 1.44, 95% CI 0.71-2.90). CONCLUSION: Centers with higher ACC case volumes have lower odds of PM and utilize OA more often. LA is associated with higher odds of PM, whereas RA is not. These factors should be considered when planning the operative approach for ACC.

Upstaging of Fibroepithelial Lesions: A Single-Institution Experience.

INTRODUCTION: Fibroepithelial lesions of the breast (FEL) are heterogeneous lesions ranging from fibroadenomas (FA) to phyllodes tumors (PT). FEL with cellular stroma are diagnostic challenges on core needle biopsy (CNB) as it is difficult to distinguish cellular FA from PT. The purpose of this study was to determine the features of FEL on CNB that may be predictive of PT, the upstage rate to PT after excision, and the outcomes of those who did not undergo excision. METHODS: Overall, 305 patients with FEL on CNB between 2009 and 2019 were identified from a prospectively maintained institutional database. Presentation, imaging, and pathology were evaluated. RESULTS: Mean age at diagnosis was 43.8 years. Pathology on CNB included 97 cases of FEL favoring FA, 19 cases of FEL favoring PT, 3 cases of FEL versus pseudoangiomatous stromal hyperplasia, and 186 cases of FEL not otherwise specified. Following CNB, 96 (31.5%) patients were observed, 158 (51.8%) patients had an excisional biopsy, 48 (15.7%) patients underwent segmental mastectomy, and 3 (1.0%) patients underwent a mastectomy. The upgrade rate from FEL on CNB to PT upon excision was 25.8%. PT on final pathology was more commonly seen when the CNB identified stromal overgrowth, necrosis, and diagnosis of FEL favoring PT. On multivariable analysis, a final diagnosis of PT was associated with age >50 years, larger tumor size >2 cm, stromal overgrowth, and ≥1 mitoses/10 high power fields (HPF) on CNB. Patients who were observed had smaller tumors compared with those who underwent excision. CONCLUSION: In this 10-year single-institution experience of FEL, the upstage rate to PT was 25.8%. Excision of FEL is recommended. Furthermore, the observation of lesions appeared to be safe in select cases, specifically in patients with smaller tumor size.

Adrenocortical Carcinoma: The Value of Lymphadenectomy.

BACKGROUND: Adrenocortical carcinoma (ACC) staging does not account for the number of positive nodes. The prognostic value of quantitative metastatic nodal burden is unknown. METHODS: The National Cancer Database was retrospectively queried from 2004-2016 to identify patients with Stage I-III ACC undergoing adrenalectomy. Patients who underwent lymphadenectomy (LAD) were further studied. Demographics, TNM staging, tumor characteristics, and surgical approach were analyzed. RESULTS: 386 LADs were identified. The median number of nodes examined was 2 (IQR 2-6), with no difference by surgical approach '[laparoscopic, 3 (1-3); robotic, 1.5 (1-4.5); open, 2 (1-7), p = 0.493]. In LADs with cN0 disease, positive nodes were seen in 17.5% of patients; an average of 6 (1-12) nodes were examined in patients who upstaged to pN1 disease compared with an average of 2 (1-6) nodes in those who remained pN0. Median survival was incrementally worse for patients with more positive nodes (62.8 vs. 21.9 vs. 13.7 vs. 11.3 vs. 10.7 months for 0, 1, 2, 3, and ≥ 4 positive nodes, respectively, p < 0.01). On multivariate analysis, significant prognostic factors for poor survival included older age, ≥ 2 comorbidities, pT3, and pT4. The strongest prognostic factor for poor survival was the number of positive nodes (1 node, hazards ratio [HR] 2.3, 95% confidence interval [CI] 1.5-3.6; 2 nodes, HR 1.3, 95% CI 0.6-3.0; 3 nodes, HR 3.0, 95% CI 1.1-8.0; ≥ 4 nodes, HR 4.0, 95% CI 2.5-6.2). Lymphadenectomy was associated with improved survival (HR 0.82, 95% CI 0.67-0.99). CONCLUSIONS: Higher quantitative metastatic nodal burden is a robust prognostic factor for worse survival in ACC.

Routine Versus Selective Liver Biopsy During Bariatric Surgery: Postoperative Outcomes and Preoperative Predictors of NASH.

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is common in patients with obesity. Liver biopsy (LB) can be routinely or selectively performed during bariatric surgery to identify patients with NASH. METHODS: Patients undergoing bariatric surgery between 2016 and 2020 at our institution were identified. Chart review identified patients undergoing concurrent LB. LB results were compared between patients undergoing routine LB and selective LB. Patient demographics and postoperative outcomes were compared between those who received LB and those who did not (non-LB). In the LB cohort, preoperative characteristics of patients with NASH were compared to those without NASH, and multivariable regression was used to identify predictors of NASH. RESULTS: Two thousand three hundred ninety-three patients were identified, of which 400 (16.7%) had liver biopsies (LB) and 1,993 (83.3%) did not (non-LB). Three hundred thirty LB were performed routinely, and 70 were selective. Compared to selective LB, routine LB identified significantly higher rates of steatosis (83.6% vs. 4.5%, p < 0.01), periportal inflammation (67.0% vs. 3.2%, p < 0.01), fibrosis (65.8% vs. 2.1%, p < 0.01), and NASH (10.9% vs. 1.5%, p < 0.01). There were no differences in postoperative complications, blood transfusions, readmissions, or reoperations between LB and non-LB. On multivariable regression, highest BMI > 40 (OR 2.85, 95% CI 1.43-5.67) and insulin-dependent diabetes (OR 4.83, 95% CI 1.70-13.69) were associated with a higher odds of NASH, while Black race was associated with lower odds (OR 0.25, 95% CI 0.09-0.65). CONCLUSIONS: Routine liver biopsies during bariatric surgery identify higher rates of advanced NAFLD compared to selective biopsies, and can be safely performed without an increased risk of postoperative complications.

Commission on Cancer CP3R Compliance Rates for Treatment of Patients With Triple Negative and HER2+ Breast Cancer: A National Cancer Database Analysis.

BACKGROUND: Cancer Program Practice Profile Reports (CP3R) metrics were released by the Commission on Cancer to provide standards for high-quality care. One metric is the recommendation of combination chemotherapy or chemo-immunotherapy (CIT) within 120 days of diagnosis for women under 70 with AJCC T1cN0M0 or Stage IB-III HER2+ or hormone receptor negative breast cancer ([Multi-agent chemotherapy] MAC). Our study assesses national concordance rates for MAC and CIT. METHODS: The National Cancer Database was queried from 2004-2014. RESULTS: 122,045 patients met criteria, of whom treatment for 101,800 (83.4%) patients was concordant with MAC and CIT. Treatment concordance increased from 75.7% in 2004 to 89.5% in 2014. For HER2+ patients, use of CIT treatment downtrended with progression of pathological stage, from 70.1% (stage I) to 58.1% (stage III). Mean overall survival of patients whose treatment was concordant with MAC and CIT was longer than that of patients who were non-concordant (146.6 vs 143.8 months, P <.01). On Cox regression, there was a survival benefit for concordant patients who were treated at academic hospitals (HR .89, 95% CI 0.802-.976) and had private insurance (HR .76, 95% CI 0.65-.89). CONCLUSION: Compliance with MAC and CIT has improved over the past decade and is associated with a significant improvement in overall survival.

Clinicopathologic Characteristics and Patient Outcomes of Phyllodes Tumors: A Single Institution Experience.

Phyllodes tumors (PT) are rare fibroepithelial neoplasms that are classified as benign, borderline, or malignant. Patients with PT diagnosed between 2009 and 2019 were identified from a prospectively maintained single institutional database. 76 patients with PT were included; 47 (61.8%) were benign, 9 (11.8%) were borderline, and 20 (26.3%) were malignant. The mean age at diagnosis was 52. Surgical treatment of benign PT included excisional biopsy in 31 (66.0%) patients, segmental mastectomy in 15 (31.9%), and mastectomy in 1 (2.1%). Among patients with borderline PT, operative management was excisional biopsy in 4 (44.4%) and segmental mastectomy in 5 (55.6%). Of those with malignant PT, 7 (35.0%) were treated with excisional biopsy alone, 9 (45.0%) had lumpectomy (segmental mastectomy), and 4 (20.0%) underwent mastectomy. Malignant PT had a higher rate of necrosis compared to borderline or benign PT (25.0% vs 0% vs 4.3%, P = .016). Four patients had recurrent PT. Final positive margins were associated with recurrence (P = .044). The median overall follow-up time was 86.3 months (range 1.5-1414.1 months), and no deaths occurred among patients with malignant PT. Overall, recurrence rates of PT are low but may be increased by presence of positive margins.

Disparities and survival in newly diagnosed gastric cancer in Hispanic patients in the United States: a propensity score matched analysis.

BACKGROUND: The burden of gastric cancer involving Hispanic patients in the United States is growing as both the population and the incidence of gastric cancer in this group increases. This burden is compounded by presentation with advanced disease and socioeconomic challenges shaping cancer care. We sought to describe the demographics, socioeconomic factors, treatment, and survival experience of Hispanic patients with gastric adenocarcinoma. METHODS: Patients with gastric adenocarcinoma diagnosed between 2004 and 2015 (n=90,737) in the National Cancer Database were retrospectively identified. Patients of Hispanic ethnicity were compared against non-Hispanic white patients. Surgical cohort was further analyzed, and 1:1 propensity score matching was used to balance covariates between Hispanic and non-Hispanic white surgical patients. Survival was compared using Kaplan-Meier method. Cox regression was used to determine prognostic factors for survival. RESULTS: Compared to non-Hispanic white patients, Hispanic patients are more likely to be younger, female, and healthier. They were more likely to be uninsured, reside in poorer neighborhoods and reside in areas with lower rates of education. Hispanic patients were more likely to live in a metropolitan area, travel shorter distances for healthcare, and receive treatment at an academic and high volume centers. Hispanic patients were more likely to have higher stage disease presentation, higher grade tumors, lymphovascular invasion, and poorly cohesive adenocarcinoma. Hispanic patients were more likely to receive surgery, but less likely to receive adjuvant therapy. In Cox regression of all patients, unmatched surgical patients, and matched surgical patients, Hispanic ethnicity was an independent prognostic factor of improved survival. CONCLUSIONS: Hispanic patients with gastric adenocarcinoma present with several unfavorable clinicopathologic and socioeconomic factors. Paradoxically, these patients demonstrate improved survival. Further study is warranted to characterize disease biology in this population.

Factors Associated with Non-Operative Management of Resectable Adrenocortical Carcinoma.

INTRODUCTION: Surgery is the initial treatment of choice for patients with resectable adrenocortical carcinoma (ACC). We sought to determine factors associated with non-operative management of resectable ACC. METHODS: 2004-2016 National Cancer Database (NCDB) was queried to identify patients with AJCC/ENSAT Stage I-III ACC. Patients who underwent surgery (S) were compared to those who did not undergo surgery (NS). Multivariate logistic regression was used to identify factors associated with NS. Kaplan-Meier estimates used to assess survival. RESULTS: Two thousand-seventy patients with Stage I-III ACC were identified, of which 17.5% were NS. 85.9% of NS patients were not offered surgery; 69.9% of NS patients did not receive chemotherapy or radiation therapy. NS were older and less likely to receive care at an Academic center or high volume center (≥5 cases during the study period). NS patients were more likely to have advanced T stage and N1 disease. On multivariate regression, factors associated with lower odds of surgery include older age (OR 1.03, 95% CI 1.02-1.06), T4 disease (OR 3.34, 95% CI 1.05-10.68), and treatment at a community center (OR 2.92, 95% CI 1.58-5.40). Overall median survival was significantly poorer for NS patients (50.4 versus 78.4 months, P < 0.01). CONCLUSION: Patients with locally advanced ACC are less likely to undergo an operation, while those treated at centers with more operative experience or Academic facilities are more likely to undergo an operation. As the surgery-first approach is the current standard of care for resectable ACC, these patients may be best served at high volume Academic facilities.

Contemporary Cancer Program Practice Profile Report (CP3R) Compliance Rates for Breast Cancer: A National Cancer Database Analysis.

INTRODUCTION: The Commission on Cancer (CoC) issues Cancer Program Practice Profile Reports (CP3R) that set standards for high-quality care. Three metrics for breast cancer include radiation within 1 year for women < 70 years of age receiving breast-conserving surgery, radiation within 1 year after mastectomy for women with four or more positive lymph nodes (MASTRT), and hormonal therapy within 1 year of a stage IB-III hormone receptor-positive breast cancer (HT). Our study evaluates national trends in quality metric compliance. METHODS: The National Cancer Database was queried from 2004 to 2014 to identify patients who met the criteria for the three quality metrics. National trends in compliance were compared. RESULTS: Overall, 1,094,264 patients qualified for BCSRT (n = 534,147), MASTRT (n = 66,291), or HT (n = 493,826). In 2014, 91.1% of patients met BCSRT, 88.4% met MASTRT, and 90.7% met HT. BCSRT, MASTRT, and HT compliance rates were lower in community hospitals compared with Integrated Network Cancer Programs (INCP) (BCSRT: 89.0% vs. 92.8%, p < 0.01; MASTRT: 85.5% vs. 90.6%, p < 0.01; HT: 87.3% vs. 93.7%, p < 0.01). On multivariate analysis, patients receiving care at an INCP facility [odds ratio (OR) 1.47, 95% confidence interval (CI) 1.37-1.58] and insured patients (OR 1.70, 95% CI 1.54-1.87) had higher odds of BCSRT compliance, and minorities (OR 0.76, 95% CI 0.73-0.80) had lower odds. Similar results were seen for MASTRT and HT. CONCLUSION: In more recent years, overall compliance rates for breast cancer quality metrics of BCSRT and HT by Comprehensive Community Cancer Programs, Academic/Research Programs, and INCPs have increased to meet the 90% CoC standards, while MASTRT has regressed. Community programs were least compliant with meeting the CoC standards.

Changes in utilization of axillary dissection in women with invasive breast cancer and sentinel node metastasis after the ACOSOG Z0011 trial.

The American College of Surgeons Oncology Group Z0011 (ACOSOG Z0011) trial demonstrated no survival advantage for women with clinical T1-T2 invasive breast cancer with 1-2 positive sentinel lymph nodes (SLN) who received whole-breast radiation, and no further axillary surgery when compared to women who did undergo axillary lymph node dissection (ALND). We used the National Cancer Database (NCDB) to study changes in utilization of ALND after the publication of this trial. NCDB was queried for female patients from 2012 to 2015 who met Z0011 criteria. Patients were divided into four groups based on Commission on Cancer facility accreditation. Outcome measures include the rate of ALND (nonadherence to Z0011) and the average number of nodes retrieved with ALND. 27,635 patients were identified, with no significant differences in T stage and receptor profiles between groups. Overall rate of ALND decreased from 34.0% in 2012 to 22.7% in 2015. Nonadherence was lowest in Academic Programs (decreasing from 30.1% in 2012 to 20.5% in 2015) and was highest in Community Cancer Programs (41.2% in 2012 to 29.1% in 2015). Median number of positive SLN did not differ between groups (p = .563). Median number of nodes retrieved on ALND decreased from 9 (IQR 5-14) in 2012 to 7 (IQR 4-12) in 2015 (p < .001). In patients who met the ACOSOG Z11 trial guidelines, rates of ALND have decreased over time. However, rates of nonadherence to Z0011 are significantly higher in Community Cancer Programs compared to Academic Programs.

The Efficacy of Collaborative Authoring of Video Scene Descriptions.

The majority of online video contents remain inaccessible to people with visual impairments due to the lack of audio descriptions to depict the video scenes. Content creators have traditionally relied on professionals to author audio descriptions, but their service is costly and not readily-available. We investigate the feasibility of creating more cost-effective audio descriptions that are also of high quality by involving novices. Specifically, we designed, developed, and evaluated ViScene, a web-based collaborative audio description authoring tool that enables a sighted novice author and a reviewer either sighted or blind to interact and contribute to scene descriptions (SDs)-text that can be transformed into audio through text-to-speech. Through a mixed-design study with N = 60 participants, we assessed the quality of SDs created by sighted novices with feedback from both sighted and blind reviewers. Our results showed that with ViScene novices could produce content that is Descriptive, Objective, Referable, and Clear at a cost of i.e., US$2.81pvm to US$5.48pvm, which is 54% to 96% lower than the professional service. However, the descriptions lacked in other quality dimensions (e.g., learning, a measure of how well an SD conveys the video's intended message). While professional audio describers remain the gold standard, for content creators who cannot afford it, ViScene offers a cost-effective alternative, ultimately leading to a more accessible medium.

Surgical Supply Cost Awareness Is Associated With Lower Costs: A Single-Center Experience.

Surgeons are often unfamiliar with the costs of surgical instrumentation and supplies. We hypothesized that surgeon cost feedback would be associated with a reduction in cost. A multidisciplinary team evaluated surgical supply costs for laparoscopic appendectomies of 7 surgeons (surgeons A-G) at a single-center academic institution. In the intervention, each surgeon was debriefed with their average supply cost per case, their partner's average supply cost per case, the cost of each surgical instrument/supply, and the cost of alternatives. In addition, the laparoscopic appendectomy tray was standardized to remove extraneous instruments. Pre-intervention (March 2017-February 2018) and post-intervention (March 2018-October 2018) costs were compared. Pre-intervention, the surgeons' average supply cost per case ranged from $754-$1189; when ranked from most to least expensive, surgeon A > B > C > D > E > F > G. Post-intervention, the surgeons' average supply cost per case ranged from $676 to $846, and ranked from surgeon G > D > F > C > E > B > A. Overall, the average cost per case was lower in the post-intervention group ($854.35 vs. $731.11, P < .001). This resulted in savings per case of $123.24 (14.4%), to a total annualized savings of $29 151.
