Association of Medicaid Expansion with Post-mastectomy Reconstruction Rates.

BACKGROUND: The Affordable Care Act sought to improve access to health care for low-income individuals. This study aimed to assess whether expansion of Medicaid coverage increased rates of post-mastectomy reconstruction (PMR) for patients who had Medicaid or no insurance. METHODS: A retrospective analysis performed through the National Cancer Database examined women who underwent PMR and were uninsured or had Medicaid, private insurance, or Medicare, and whose race/ethnicity, age, and state expansion status were known. Trends in the use of PMR after passage of Medicaid expansion in 2014 were evaluated. RESULTS: In all states and at all time periods, patients with private insurance were about twice as likely to undergo PMR as patients who had Medicaid or no insurance. In 2016, only 28.7 % of patients with Medicaid or no insurance in nonexpansion states underwent PMR (p < 0.001) compared with 38.5 % of patients in expansion states (p < 0.001). Patients in expansion states also have higher levels of education, higher income, and greater likelihood of living in metropolitan areas. Additionally, patients in all states saw an increase in early-stage disease, with a concomitant reduction in late disease, but this change was greater in expansion states than in non-expansion states. CONCLUSIONS: Expansion states have larger proportions of patients undergoing PMR than non-expansion states. This difference stems from significant differences in income, education, comorbidities, race, and location. Large metropolitan areas have the largest number of patients undergoing PMR, whereas rural areas have the least.

Apocrine Breast Cancer: Unique Features of a Predominantly Triple-Negative Breast Cancer.

INTRODUCTION: Invasive apocrine carcinoma is a rare breast cancer that is frequently triple negative. Little is known about the characteristics of its molecular subtypes. We compared the incidence, demographics, and clinicopathologic features of this cancer with non-apocrine carcinomas stratified by molecular subtype. METHODS: Women with invasive apocrine cancer were retrospectively identified from the Surveillance, Epidemiology, and End Results (SEER) database. Clinicopathologic and demographic features were compared with non-apocrine carcinomas, both overall using data from 2004 to 2017 and stratified by molecular subtypes using data from 2010 to 2017. The life table method was used to determine the 7-year breast cancer-specific survival. RESULTS: Compared with non-apocrine cancers, apocrine cancers presented at a younger age, with larger, higher-grade tumors that were much more likely to be triple negative (50% vs. 11%) or human epidermal growth factor receptor 2 (HER2)-positive (28% vs. 15%) and less likely to be luminal (22% vs. 74%); however, the 7-year survival was the same at 85%. The characteristics varied dramatically by molecular type. Compared with non-apocrine triple-negative, apocrine triple-negative patients were less likely to be African American and were much older, with smaller, lower-grade tumors and much better survival (86% vs. 74%). In contrast, compared with luminal non-apocrine, apocrine luminal patients had larger, higher-grade tumors and worse survival (79% vs. 89%). CONCLUSIONS: Invasive apocrine carcinomas have more aggressive features than non-apocrine carcinomas but the breast cancer-specific survival is the same. Half of these apocrine tumors are triple negative but these have more favorable features and much better survival than non-apocrine triple-negative cancers.

Immunotherapy Treatment for Triple Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is considered one of the highest-risk subtypes of breast cancer and has dismal prognosis. Local recurrence rate after standard therapy in the early breast cancer setting can be upwards to 72% in 5 years, and in the metastatic setting, the 5-year overall survival is 12%. Due to the lack of receptor expression, there has been a paucity of targeted therapeutics available, with chemotherapy being the primary option for systemic treatment in both the neoadjuvant and metastatic setting. More recently, immunotherapy has revolutionized the landscape of cancer treatment, particularly immune checkpoint inhibitor (ICI) therapy, with FDA approval in over 20 types of cancer since 2011. Compared to other cancer types, breast cancer has been traditionally thought of as being immunologically cold; however, TNBC has demonstrated the most promise with immunotherapy use, a timely discovery due to its lack of targeted therapy options. In this review, we summarize the trials using checkpoint therapy in early and metastatic TNBC, as well as the development of biomarkers and the importance of immune related adverse events (IRAEs), in this disease process.

Comparison of carbon dioxide and iodinated contrast for cavography prior to inferior vena cava filter placement.

BACKGROUND: The use of iodinated contrast in the critically ill trauma patient has been associated with the development of acute renal failure. The low incidence of nephrotoxicity associated with carbon dioxide (CO(2)) makes it an ideal contrast agent for cavography. However, the use of CO(2) has been limited, because reportedly it underestimates the diameter of the inferior vena cava (IVC). METHODS: During a 6-month period (January 2000 through June 2000), 25 adult trauma patients required IVC filter placement. Bedside cavagrams using CO(2) followed by iodinated contrast were employed to determine the diameter of the IVC and the anatomy of the renal veins. RESULTS: Using CO(2) injection for cavography, we were able to determine the diameter of the IVC and the anatomy of the renal veins in all patients. Furthermore, when CO(2) cavography was compared with the results obtained with iodinated contrast, the difference in diameter of the IVC was within 1 mm. CONCLUSIONS: Based on these data, it was determined that CO(2) cavagrams accurately reflect the diameter of the IVC and the anatomy of the renal veins. Additionally, CO(2) cavagrams can be safely performed in the intensive care unit during bedside placement of IVC filters.

Thoracoscopic application of a topical sealant for the management of persistent posttraumatic pneumothorax.

BACKGROUND: Persistent posttraumatic pneumothorax (PPP) is an uncommon complication of blunt or penetrating chest trauma. Currently, most patients are managed with pleural chest tube(s) and suction drainage. Prolonged hospital stay and added cost of care are not uncommon. METHODS: Over a 2-year period, 13 patients with PPP, nonresponsive to conventional management, underwent video-assisted thoracoscopic surgery (VATS). As part of our protocol for PPP, routine preoperative computed tomography of the chest and bronchoscopy to determine the presence of associated injuries were performed in all of the patients. During the VATS procedure, all of the patients underwent drainage of any retained hemothorax, and a topical surgical sealant was applied to the source of the air leak as definitive treatment. RESULTS: A persistent pneumothorax with an air leak was identified in all 13 of the patients. There were 10 patients with blunt and 3 patients with penetrating injuries, respectively. The mean age for the patients was 34 years (range, 13 to 64 years). Parenchymal lacerations were identified in all of the patients ranging in size from 0.5 to 3 cm. After the VATS procedure and application of the surgical sealant, 11 patients had the chest tubes removed within 24 hours of the procedure. In the other two patients, the chest tubes were removed within 48 hours. There was no recurrence of the pneumothorax in any of these patients. The mean length of hospital stay before VATS and the application of the surgical sealant was 6 days (range, 2-14 days). CONCLUSION: Early VATS and the use of a topical sealant in patients with PPP is a safe and effective alternative to the conventional management with prolonged thoracostomy chest tubes or an open thoracostomy. This alternative management, when used early in the appropriate patient, will decrease the length of hospital stay, cost of care, and unnecessary procedures.
