There is little data exploring the impact of screening mammography on subsequent treatment in the 40-49-year age group with breast cancer. We sought to assess the association between frequency of mammography in young women and extent of surgery and chemotherapy required.An IRB-approved retrospective review was performed of patients diagnosed with breast cancer between ages 40 and 49 years from 1 January 2010 to 19 November 2018 within a single health system. Patients were grouped based on last screening 1-24 months prior to diagnosis (1-24 group),25 months prior to diagnosis (25 group), never screened, and25+ never screened (combination group). Multivariate logistic regression models were used to assess for associations between screening intervals and tumor and nodal stage, chemotherapy use, and extent of surgery.Of 869 patients included for analysis, 20% were never screened, 60% screened 1-24 months, and 19% screened25 months prior to diagnosis. Compared with the 1-24 months group, the never-screened group,25 months group, and combined group were more likely to receive chemotherapy. The never-screened and combined groups were more likely to undergo mastectomy and/or axillary lymph node dissection. Of patients undergoing upfront surgery, the25 months and combined groups were more likely to receive adjuvant chemotherapy, while the never-screened and combined groups were more likely to have nodal disease.Our findings support the initiation of screening mammography at age 40 years to reduce the risk of aggressive treatments for newly diagnosed breast cancers in this group.

Anatomic extent of ductal carcinoma in situ (DCIS) may be uncertain in spite of clinical, pathologic, and imaging data. Consequently close/positive margins are common with lumpectomy for DCIS and often lead to a challenge in deciding whether to perform a re-excision or mastectomy.From a single health system, we identified cases of lumpectomy for DCIS with close/positive margins who underwent re-excision for the purpose of constructing a nomogram. In total, 289 patients were available for analysis. The patients were randomly divided into two sets allocating 70% to the modeling and 30% to the validation set. A multivariable logistic regression model was used to estimate the probability of overall positive margin status using multiple clinicopathologic predictors. Nomogram validation included internal tenfold cross-validation, internal bootstrap validation, and external validation for which a concordance index was calculated to assess the external validity.Significant predictors of persistent positive margins from regression modeling included necrosis at diagnosis (non-comedo or comedo); DCIS not associated with calcifications on core biopsy; high-grade DCIS; progesterone receptor positivity; and number of positive margins at initial surgery. When subjected to internal validation, the nomogram achieved an uncorrected concordance index of 0.7332, a tenfold cross-validation concordance index of 0.6795, and a bootstrap-corrected concordance index of 0.6881. External validation yielded an estimated concordance index of 0.7095.Using clinical and pathologic variables from initial diagnosis and surgery for DCIS, this nomogram predicts persistent positive margins with margin re-excision, and may be a valuable tool in surgical decision-making.

Guidelines recommend hepatitis B (HBV) testing in individuals from endemic areas, and if positive, screening for hepatocellular carcinoma (HCC). While screening programs are well established in the Asian immigrant population in New York City (NYC), less is known about the characteristics of HBV/HCC among the African immigrant community. A retrospective review was performed of HCC cases from 2005 to 2018 at our institution. Country of origin was not documented in the electronic medical record; therefore, African immigrant status was approximated using self-identified race/ethnicity, positive HBV status, and an online registry to determine country of origin based on last name. Surnames with the greatest prevalence or density in an African country were considered. Among 4400 patients with HCC, 472 identified as non-Hispanic Black; of these, 86 were HBV+. Based on surname, it was estimated that 33 individuals were likely immigrants from Africa. In this group, median age of HCC diagnosis was 48 years (IQR 43–55). In patients with an available date of HBV diagnosis (n = 24), 17 (71%) were unaware of their HBV status when they presented with HCC. Zero patients were diagnosed with HCC through routine screening, most patients (66%) were diagnosed upon imaging evaluation of symptoms. Twelve patients (36%) underwent resection or transplantation; the remaining 64% were ineligible for surgical treatment. Of the 26 patients with follow-up data, 18 (69%) died of disease or were critically ill at last encounter, and of these, 14 (77%) died within 1 year of HCC diagnosis. In conclusion, African immigrants in NYC with HBV/HCC are at high risk of HCC related mortality at a young age. Most were unaware of their hepatitis status at the time of HCC diagnosis. No patients were enrolled in routine HCC screening; the majority were diagnosed based on imaging obtained for symptoms. Most individuals presented with inoperable disease, and the majority died within months of diagnosis. Awareness of these findings may help healthcare providers improve patient outcomes.

BACKGROUND In the United States, mortality after a diagnosis of hepatocellular carcinoma (HCC) is higher in patients who are Black than in patients of other racial groups. The objective of this study was to clarify factors contributing to this disparity by analyzing liver and tumor characteristics in patients with HCC who have a history of hepatitis C virus (HCV) infection. METHODS Records of patients with HCV and HCC at the authors' institution from 2003 to 2018 were retrospectively reviewed. Race and ethnicity were self-identified. Imaging, laboratory, and pathologic features were compared between Black and non-Black cohorts. RESULTS Among 1195 individuals with HCC, 390 identified as Black. At the time of HCC diagnosis, Black patients had better liver function, as measured by Child-Pugh score, Model of End-Stage Liver Disease score, histology of nontumor tissue, and fibrosis-4 (FIB-4) score (all P < .05). FIB-4 scores were
