Clinical and Histopathologic Features of 35 Patients Treated for Colorectal Peritoneal Metastases Who Survived 5 Years.

BACKGROUND: Currently, patients with a limited extent of peritoneal metastases from colon and rectal cancer are treated by cytoreductive surgery combined with perioperative chemotherapy performed at experienced centers. OBJECTIVE: To statistically evaluate features that may impact survival of ≥5 years. These data are used in the risk/benefit analyses performed by the multidisciplinary team. DESIGN: This was a retrospective review of a prospective database. SETTINGS: This single-institution study was conducted at an academic center. PATIENTS: All patients who had biopsy-proven colon or rectal peritoneal metastases treated by systemic chemotherapy, complete cytoreductive surgery, and perioperative surgery were included. MAIN OUTCOME MEASURES: The primary outcomes measured were the clinical-, histologic-, and treatment-related features that had an impact on 5-year survival. RESULTS: From 131 patients who had complete cytoreduction, 35 patients (26.7%) were identified as 5-year survivors. The median survival time was 27 months. The median age was 50.5 (range, 25-80) years. By univariant analysis, an absence of lymph node involvement at the time of primary colorectal cancer resection (HR 1.899 [95% CI, 1.064-3.388]; p = 0.03), complete or near-complete response to neoadjuvant chemotherapy (HR 0.251 [95% CI, 0.092-0.684]; p = 0.007), peritoneal cancer index ≤17 (HR 0.509 [95% CI, 0.329-0.788]; p = 0.002), complete visible resection of disease indicated by the completeness of cytoreduction score of 0 (HR 0.412 [95% CI, 0.224-0.756]; p = 0.004), and well-differentiated tumor (HR 0.34 [95% CI, 0.157-0.737]; p = 0.006) were significantly associated with ≥5 years survival. LIMITATIONS: Limitations include its retrospective nature, unmeasured confounders, and data from a single institution. CONCLUSIONS: The tumor biology as revealed by lymph node status and tumor differentiation plus extent of disease as measured by the response to neoadjuvant chemotherapy, peritoneal cancer index, and no visible residual disease indicated a favorable outcome.

Persistent Disparities in Access to Elective Colorectal Cancer Surgery After Medicaid Expansion Under the Affordable Care Act: A Multistate Evaluation.

BACKGROUND: Despite their higher incidence of colorectal cancer, ethnoracial minority and low-income patients have reduced access to elective colorectal cancer surgery. Although the Affordable Care Act's Medicaid expansion increased screening of colonoscopies, its effect on disparities in elective colorectal cancer surgery remains unknown. OBJECTIVE: This study assessed the effects of Medicaid expansion on elective colorectal cancer surgery rates overall and by race-ethnicity and income. DESIGN: Using the 2012 to 2015 State Inpatient Databases, a retrospective cohort study was conducted. SETTINGS: State Inpatient Databases from 3 expansion states (Maryland, New Jersey, and Kentucky) and 2 nonexpansion states (Florida and North Carolina) were used. PATIENTS: This study examined 22,304 adult patients aged 18 to 64 years who underwent colorectal cancer surgery. MAIN OUTCOME MEASURES: Using interrupted time series analysis, the effect of Medicaid expansion on the odds of elective colorectal cancer surgery was assessed. RESULTS: Elective vs nonelective surgery rates remained unchanged overall (70.2% vs 70.7%, p = 0.63) and in ethnoracial minorities in expansion states (whites from 72.8% to 73.8% pre to post, p = 0.40 and non-white from 64.0% to 63.1% pre to post, p = 0.67). There was an instantaneous increase in odds of elective surgery in expansion vs nonexpansion states at policy implementation (adjusted OR 1.37; 95% CI, 1.05-1.79; p = 0.02), but it subsequently decreased (combined adjusted OR 0.95; 95% CI, 0.92-0.99; p = 0.03). Elective surgery rates were also unchanged among ethnoracial minorities (instantaneous changes in expansion states, combined effect 1.06; pre-trend 1.01 vs post-trend 0.98) and low-income persons in expansion states (pre-trend 1.03 vs post-trend 0.97) (for all, p > 0.1). LIMITATIONS: The study was limited to 5 states. Although patients may have increased access to cancer screening services and surgery after expansion, the State Inpatient Databases only provide information on patients who underwent surgery. CONCLUSIONS: Despite gains in screening, Medicaid expansion was not associated with reductions in known ethnoracial or income-based disparities in elective colorectal cancer surgery rates. Expanding access to colorectal cancer surgery for underserved populations likely requires attention to provider and health system factors contributing to persistent disparities.

DISPARIDADES PERSISTENTES EN EL ACCESO A LA CIRUGA ELECTIVA DEL CNCER COLORRECTAL DESPUS DE LA EXPANSIN DE MEDICAID EN VIRTUD DE LA LEY DEL CUIDADO DE SALUD A BAJO PRECIO UNA EVALUACIN MULTIESTATAL: ANTECEDENTES: A pesar de su mayor incidencia de cáncer colorrectal, los pacientes de minorías etnoraciales y de bajos ingresos tienen un acceso reducido a la cirugía electiva de cáncer colorrectal. Aunque la expansión de Medicaid de la Ley del Cuidado de Salud a Bajo Precio aumentó las colonoscopias de detección, aún se desconoce su efecto sobre las disparidades en la cirugía electiva de cáncer colorrectal.OBJETIVO: Este estudio evaluó los efectos de la expansión de Medicaid en las tasas de cirugía electiva de cáncer colorrectal en general y por raza, etnia e ingresos.DISEÑO: Utilizando las bases de datos estatales de pacientes hospitalizados de 2012-2015, se realizó un estudio de cohorte retrospectivo.CONFIGURACIÓN: Se utilizaron bases de datos estatales de pacientes hospitalizados de tres estados en expansión (Maryland, Nueva Jersey, Kentucky) y dos estados sin expansión (Florida, Carolina del Norte).PACIENTES: Este estudio examinó a 22,304 pacientes adultos de 18 a 64 años que se sometieron a cirugía de cáncer colorrectal.RESULTADO PRINCIPAL: Mediante el análisis de series de tiempo interrumpido, se evaluó el efecto de la expansión de Medicaid en las probabilidades de cirugía electiva de cáncer colorrectal.RESULTADOS: Las tasas de cirugía electiva frente a no electiva permanecieron sin cambios en general (70,2% frente a 70,7%, p = 0,63) y en las minorías etnoraciales en los estados de expansión (blancos del 72,8% al 73,8 % antes y después, p = 0,40 y no blancos del 64,0% al 63,1% pre a post, p = 0,67). Hubo un aumento instantáneo en las probabilidades de cirugía electiva en los estados de expansión frente a los de no expansión en la implementación de la política (OR ajustado 1,37, IC del 95%, 1,05-1,79, p = 0,02), pero disminuyó posteriormente (OR ajustado combinado 0,95, 95% IC, 0,92-0,99, p = 0,03). Las tasas de cirugía electiva también se mantuvieron sin cambios entre las minorías etnoraciales (cambios instantáneos en los estados de expansión, efecto combinado 1,06; antes de la tendencia 1,01 frente a la postendencia 0,98) y las personas de bajos ingresos en los estados de expansión (antes de la tendencia 1,03 frente a la postendencia 0,97; para todos, p > 0,1).LIMITACIONES: El estudio se limitó a cinco estados. Si bien los pacientes pueden tener un mayor acceso a los servicios de detección de cáncer y la expansión posterior a la cirugía, la base de datos de pacientes hospitalizados del estado solo brinda información sobre los pacientes que se sometieron a cirugía.CONCLUSIONES: A pesar de los avances en la detección, la expansión de Medicaid no se asoció con reducciones en las disparidades etnoraciales o basadas en los ingresos conocidas en las tasas de cirugía electiva de cáncer colorrectal. Ampliar el acceso a la cirugía del cáncer colorrectal para las poblaciones desatendidas probablemente requiera atención a los factores del proveedor y del sistema de salud que contribuyen a las disparidades persistentes.

Alcohol-associated liver disease predicts increased post-liver transplant opioid use.

BACKGROUND: Alcohol-associated liver disease (ALD) is a rising indication for liver transplantation (LT). Prolonged opioid use after LT leads to increased graft loss and mortality. The aim is to determine if patients transplanted with a primary diagnosis of ALD had higher risk of post-LT opioid use (p-LTOU) compared to non-ALD patients. METHODS: This is a retrospective study of patients who underwent LT between 2015 and 2018 at Medstar Georgetown Transplant Institute. Patients with prolonged hospitalization post-LT (>90 days), death within 90 days post-LT, and re-transplants were excluded. RESULTS: Two hundred and ninety seven patients were transplanted, among 29% for indications of ALD. ALD patients were younger (52 vs. 56 years), more likely to be male (76% vs. 61%), Caucasian (71% vs. 44%), have higher MELD (28.8±8.8 vs. 25±8.8), and psychiatric disease than non-ALD patients (P < .05). There was no difference in pre-LT use of opioids, tobacco, marijuana, or illicit drugs between ALD and non-ALD patients. Pre-LT opioid use (OR = 11.7, P < .001), ALD (OR = 2.5, P = .01), and MELD score (OR = .95, P = .02) independently predicted 90-day p-LTOU. CONCLUSIONS: ALD, pre-LT opioid use, and MELD score independently predict p-LTOU. Special attention should be paid to identify post-LT prolonged opioid use in ALD patients.

Prevalence of pelvic floor disorders, associations of endocrine therapy, and surgical intervention among breast cancer survivors.

INTRODUCTION AND HYPOTHESIS: To evaluate prevalence of pelvic floor disorders, association of endocrine therapy with pelvic floor disorders, and rates of pelvic floor surgery among breast cancer survivors compared to matched controls without history of cancer. METHODS: This is a retrospective, cohort study using electronic medical record data from a ten-hospital regional healthcare system. A total of 19,483 women diagnosed with breast cancer between January 2008 and April 2020 were propensity score matched to 19,483 women without a history of cancer. Medical charts were abstracted for ICD-9 and ICD-10 codes for pelvic floor disorders, use of endocrine therapy, and CPT codes for pelvic floor surgeries and procedures. RESULTS: Overall, the prevalence of pelvic floor disorders was lower among breast cancer survivors (8.8% vs. 22.6%, p < 0.001), and mean time to development of pelvic floor disorders among breast cancer survivors was 3 years. Selective estrogen receptor modulators and aromatase inhibitors were associated with pelvic organ prolapse and stress urinary incontinence, while estrogen antagonists were associated with urge urinary incontinence and lower urinary tract symptoms. Women with breast cancer had similar or higher rates of pelvic floor surgery compared to matched controls. CONCLUSIONS: Rates of pelvic floor disorders were lower among breast cancer survivors compared to controls but rates of surgical intervention did not differ and were higher for some conditions among breast cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Screening for these disorders should be considered as part of routine survivorship care.

Prognostic factors for overall survival in malignant ureteral obstruction.

INTRODUCTION: To identify prognostic factors for overall survival (OS) in patients with malignant ureteral obstruction (MUO) from gynecologic malignancy (GM), with the goal of improving patient selection for urinary diversion. MATERIALS AND METHODS: Retrospective review of 126 patients with MUO from GM at two academic centers from 2011-2019. Factors related to OS identified by Cox regression proportional hazard model. In patients with incomplete survival data (n = 30), hospice was used as a surrogate for death. Multivariate models and receivers operating characteristics (ROC) curves were created for hemoglobin and albumin values. RESULTS: Overall median survival was 6.2 months. On univariate analysis, age at diagnosis, Charlson Comorbidity Index (CCI) ≥ 8, advanced clinical stage, ascites, pleural effusion, albumin, and hemoglobin were associated with poor OS. OS was higher for those receiving ureteral stenting as compared with no intervention. There was no survival difference based on hydronephrosis grade, stent failure (SF), or creatinine at the time of intervention. On multivariate analysis, albumin < 2.85 g/dL and hemoglobin < 9.6 g/dL were predictive of poor OS. CONCLUSIONS: OS in patients with MUO due to GM is poor. Several prognostic factors for poor survival including low serum albumin and hemoglobin were identified. Ureteral stenting was associated with improved OS compared to observation, but selection bias likely contributed to this result. Additional studies are needed to clarify this finding. These data can be utilized to counsel patients regarding outcomes after urinary diversion in the setting of MUO and perhaps avoid additional procedures in some of these patients who will not derive meaningful benefit.

Immunotherapy-Associated Hypothyroidism: Comparison of the Pre-Existing With De-Novo Hypothyroidism.

Background: Immunotherapy has revolutionized the treatment of solid malignancies, but is associated with endocrine-related adverse events. This study aims to dissect the natural course of immunotherapy-induced hypothyroidism and provide guidance regarding diagnosis and management in patients with and without pre-existing hypothyroidism. Methods: A retrospective analysis was conducted using patients who received immunotherapy between 2010-2019 within a multicenter hospital system. Participants were separated in three groups-those with pre-existing hypothyroidism, those who developed primary hypothyroidism and those with hypophysitis within a year of their first immunotherapy. Serial effects of immunotherapy on thyroid function tests (TFTs) and levothyroxine dosing were evaluated. Results: 822 patients were screened, with 85 determined to have pre-existing hypothyroidism, 48 de-novo primary hypothyroidism and 12 de-novo hypophysitis. All groups displayed fluctuations in TFTs around weeks 6-8 of treatment. In the pre-existing hypothyroidism group, the levothyroxine dose was higher at 54 weeks than at baseline with the difference showing a trend towards statistical significance (p=0.06). The observed mean levothyroxine dose was significantly lower than the mean calculated weight-based dose for all groups. This finding was most clinically significant for the de-novo hypophysitis group (mean difference: -58.3 mcg, p<0.0001). The mean 0.9 mcg/kg levothyroxine dose at week 54 for the de-novo hypophysitis group was statistically lower than the other groups (p=0.009). Conclusion: It is reasonable to screen with TFTs every 4 weeks, and space out TFTs surveillance to every 12 weeks after week 20. Our findings suggest a more conservative approach for levothyroxine dosing in those developing de-novo hypothyroidism, especially hypophysitis, such as initiating at 0.9-1.2 mcg/kg.

Can Clinical Response Predict Pathologic Response Following Neoadjuvant Chemoradiation for Esophageal Cancer?

OBJECTIVES: Approximately 20-40% of patients with locally advanced esophageal cancer will achieve a pathologic complete response (ypCR) following neoadjuvant chemoradiotherapy (nCRT). Predicting ypCR based on a clinical complete response (ycCR) has been a challenge. This study assessed the correlation between ycCR and ypCR, as determined from esophagectomy specimens. METHODS: Patients undergoing esophagectomy following nCRT at three major institutions between 2005 and 2018 were reviewed. Restaging, including PET/CT, endoscopy with biopsy, and esophageal ultrasound (EUS), was performed to determine ycCR. RESULTS: Six hundred sixty patients were included, with 93.3% with esophageal adenocarcinoma histology. Six hundred fifty-eight of these patients underwent PET, 304 EUS, and 584 underwent a biopsy. Following nCRT, 148 (22.4%) were found to have a ypCR. Only 12/32 (37.5%) determined to have a ycCR were found to have a ypCR, while 136/628 (21.6%) with a non-ycCR were found to have a ypCR (p 0.075). Individual modality PPV was 28% for PET, 54% for EUS, and 26% for biopsy. When PET was combined with EUS, 168 reports were concordant and the PPV of ypCR was 50%, though the number of patients was low (1/2). With all 3 re-staging modalities combined, the PPV and NPV both rose to 100%. CONCLUSIONS: Current restaging tools cannot reliably predict ypCR after nCRT. While multimodal restaging appears to be a more accurate predictor of ypCR than any testing modality alone, patients cannot reliably be advised to avoid an esophagectomy on the assumption that ycCR predicts ypCR at this time.

National evaluation of patterns and predictors of underuse of multimodal therapy for high-risk extremity soft tissue sarcoma.

BACKGROUND: Treatment of high-risk extremity soft tissue sarcomas remains widely varied. Despite growing support for a multimodal approach for treatment of these rare and aggressive neoplasms, its dissemination remains underused. This national study aimed to evaluate variations in treatment patterns and uncover factors predictive of underuse of multimodal therapy in high-risk extremity soft tissue sarcomas. METHODS: The 2010 to 2015 National Cancer Database was used to evaluate trends in 3 common treatment patterns: surgery alone, surgery + adjuvant therapy, and neoadjuvant therapy + surgery. Demographic-, sarcoma-, hospital-, and treatment-level factors of 6,725 surgically treated patients with stage II or III intermediate- to high-grade extremity soft tissue sarcomas were evaluated by types of treatment modality. Stepwise multivariable logistic regression was performed to identify factors predictive of each treatment modality. RESULTS: When compared to surgery alone (34.6%) and adjuvant therapy (41.2%), use of neoadjuvant therapy + surgery for high-risk extremity soft tissue sarcomas remained low (25.3%). However, time trend analysis demonstrated that neoadjuvant therapy + surgery has significantly increased by 7% per year, whereas surgery alone decreased by 4% every year (P < .05 for both). Factors predictive of surgery alone were older age, nonprivate insurance, increasing travel distance, and multimorbidity (P < .05). Conversely, factors associated with neoadjuvant therapy + surgery were private insurance, higher education, and care at academic or high-volume institutions (for all, P < .05). Tumor-related factors predictive for neoadjuvant therapy + surgery included size <5 cm and higher-grade tumors (P < .05). CONCLUSION: Adoption of multimodality therapy for high-risk extremity soft tissue sarcomas remains low and gradual in the United States. Dissemination of multimodality therapy will require attention to access and hospital factors to maximize these therapies for high-risk extremity soft tissue sarcomas.

Thrombotic and Clinical Outcomes in Patients with Hematologic Malignancy and COVID-19.

BACKGROUND: Venous thromboembolism (VTE) is a common complication in acute COVID-19 and those with hematologic malignancy (HM) may be at an even higher risk. We performed a retrospective analysis of patients with history of HM and acute COVID-19 to evaluate thrombotic and clinical outcomes. METHODS: Patients with COVID-19 were identified by positive SARS-CoV-2 PCR test. Our primary endpoints were rate of VTE and CVA in patients with HM compared to the general population (GP). Secondary outcomes included composite thrombotic events (CVA + VTE), COVID-19 fatality, respiratory support, ICU admission rates, and length of ICU stay RESULTS: A total of 833 patients were evaluated, 709 in the GP cohort, 124 patients in the HM cohort. CVA was more prevalent in the HM cohort (5.4% vs. 1.6%, P = .011). Rates of VTE were numerically higher for the HM cohort (8.0% vs. 3.6%, P = .069). The composite thrombotic rate was increased in the HM cohort (13.4% vs. 5.2%, P = .005). Patients with HM had a higher inpatient fatality rate (35.5% vs. 11.3%, P < .001), required more respiratory support (74.6% vs. 46.5%, P < .001) and had a higher rate of ICU admission (31.9% vs. 12.1%, P = .001). CONCLUSION: Our data demonstrated an increased rate of composite thrombotic (CVA + VTE) outcomes, indicating HM patients with acute COVID-19 are at increased risk of thrombosis. Irrespective of disease status, HM patients also have significantly increased need for intensive care, respiratory support, and have higher fatality rates.

Risk factors for bleeding hepatocellular adenoma in a United States cohort.

BACKGROUND & AIMS: Known risk factors for hepatocellular adenoma (HCA) bleeding are size >5 cm, growth rate, visible vascularity, exophytic lesions, ß-catenin and Sonic Hedgehog activated HCAs. Most studies are based on European cohorts. The objective of this study is to identify additional risk factors for HCA bleeding in a US cohort. METHODS: Retrospective chart review was performed on patients diagnosed with HCA on magnetic resonance imaging (n = 184) at an academic tertiary institution. Clinical, pathological, and imaging data were collected. Primary outcomes measured were HCA bleeding and malignancy. Statistical analysis was performed with SAS 9.4 using Chi-Square, Fisher's exact test, sample t test, non-parametric Wilcoxon test, and logistic regression. RESULTS: After excluding patients whose pathology showed focal nodular hyperplasia and non-adenoma lesions, follow-up data were available for 167 patients. 16% experienced microscopic or macroscopic bleeding and 1.2% had malignancy. HCA size predicted bleeding (P < .0001) and no patients with lesion size <1.8 cm bled. In unadjusted analysis, hepatic adenomatosis (≥10 lesions) trended towards 2.8-fold increased risk of bleeding. Of patients with a single lesion that bled, 77% bled from a lesion >5 cm. In patients with multiple HCAs that bled, 50% bled from lesions <5 cm. In patients with multiple adenomas, size (P = .001) independently predicted bleeding and hepatic steatosis trended towards increased risk of bleeding (P = .05). CONCLUSIONS: In a large US cohort, size predicted increased risk of HCA bleeding while hepatic adenomatosis trended towards increased risk of bleeding. In patients with multiple HCAs, size predicted bleeding and hepatic steatosis trended toward increased risk of bleeding.

A New Reality for Multiple Myeloma Renal Failure: US Data Report on Kidney Transplant Outcomes.

INTRODUCTION: Describe graft and overall survival outcomes in multiple myeloma (MM) patients who underwent kidney transplant (KT) compared to the general KT population. PATIENTS AND METHODS: The Organ Procurement and Transplantation Network/National United Network for Organ Sharing (OPTON/UNOS) database was analyzed from 1988 to 2019 with R 4.00 and the 2013-2017 United States Renal Data System (USRDS) was surveyed for incidence and mortality of MM ESRD. RESULTS: USRDS analysis revealed 961 patients diagnosed with ESRD due to MM on average annually, accounting for 0.8% of the ESRD population. Without KT, 44.4% of MM patients died in the first year of renal replacement initiation. OPTON/UNOS analysis identified 218 MM KT patients, compared to 490,089 patients without MM. There was no difference in graft survival between MM KT and the general population (P-value = .13, HR = 1.19 [0.95, 1.49], 95% CI). Median graft survival in MM KT was 2683 days (7.4 years). KT patients with MM had a higher risk for death (P-value = <.0001, HR = 1.83 [1.41, 2.37], 95% CI), and median overall survival was 3076 days (8.4 years). Survival difference was lost when comparing patients ≥50 years (P-value = .42, HR = 1.14 [0.83, 1.56], 95% CI). CONCLUSION: Patients with MM renal failure who underwent KT had equivalent graft and age-matched overall survival compared to the general KT population. Therefore select patients with MM renal failure have potential for excellent KT outcomes, should be considered for transplantation when feasible, and should not be excluded from KT based on a history of MM.

ACA Medicaid expansion reduced disparities in use of high-volume hospitals for pancreatic surgery.

BACKGROUND: Early evaluation of the Affordable Care Act's Medicaid expansion demonstrated persistent disparities among Medicaid beneficiaries in use of high-volume hospitals for pancreatic surgery. Longer-term effects of expansion remain unknown. This study evaluated the impact of expansion on the use of high-volume hospitals for pancreatic surgery among Medicaid and uninsured patients. METHODS: State inpatient databases (2012-2017), the American Hospital Association Annual Survey Database, and the Area Resource File from the Health Resources and Services Administration, were used to examine 8,264 non-elderly adults who underwent pancreatic surgery in nine expansion and two non-expansion states. High-volume hospitals were defined as performing 20 or more resections/year. Linear probability triple differences models measured pre- and post-Affordable Care Act utilization rates of pancreatic surgery at high-volume hospitals among Medicaid and uninsured patients versus privately insured patients in expansion versus non-expansion states. RESULTS: The Affordable Care Act's expansion was associated with increased rates of utilization of high-volume hospitals for pancreatic surgery by Medicaid and uninsured patients (48% vs 55.4%, P = .047) relative to privately insured patients in expansion states (triple difference estimate +11.7%, P = .022). A pre-Affordable Care Act gap in use of high-volume hospitals among Medicaid and uninsured patients in expansion states versus non-expansion states (48% vs 77%, P < .0001) was reduced by 15.1% (P = .001) post Affordable Care Act. A pre Affordable Care Act gap between expansion versus non-expansion states was larger for Medicaid and uninsured patients relative to privately insured patients by 24.9% (P < .0001) and was reduced by 11.7% (P = .022) post Affordable Care Act. Rates among privately insured patients remained unchanged. CONCLUSION: Medicaid expansion was associated with greater utilization of high-volume hospitals for pancreatic surgery among Medicaid and uninsured patients. These findings are informative to non-expansion states considering expansion. Future studies should target understanding referral mechanism post-expansion.

HIV testing in patients who are HCV positive: Compliance with CDC guidelines in a large healthcare system.

BACKGROUND: There are approximately 300,000 people in the United States who are co-infected with HIV and HCV. Several organizations recommend that individuals who are HCV infected, as well as persons over the age of 13, should be HIV tested. Comorbidities associated with HCV can be reduced with early identification of HIV. Our objective was to determine whether providers routinely followed HIV testing guidelines for patients who tested HCV positive (HCV+). METHODS: A retrospective chart review was conducted of all patients in primary care at an academic health system from 7/2015-3/2017 who tested HCV+. As part of a primary database, HCV testing data was collected; HIV testing data was abstracted manually. We collected and described the intervals between HCV and HIV tests. To determine associations with HIV testing univariable and multivariable analyses were performed. RESULTS: We identified 445 patients who tested HCV+: 56.6% were tested for HIV, the mean age was 57 ± 10.9 years, 77% were from the Birth Cohort born 1945-1965 (BC); 61% were male; and 51% were Black/AA. Patients in the BC were more likely to be HIV tested if they were: male (p = 0.019), Black/AA (p<0.001), and had Medicaid (p = 0.005). These differences were not found in the non-BC. Six patients who were tested for both HIV and HCV were found to be newly HIV positive at the time of testing. CONCLUSION: As demonstrated, providers did not routinely follow CDC recommendations as almost half of the HCV+ patients were not correctly tested for HIV. It is important to emphasize that six persons were tested HIV positive simultaneously with their HCV+ diagnosis. If providers did not follow the CDC guidelines, then these patients may not have been identified. Improvements in EHR clinical decision support tools and provider education can help improve the HIV testing rate among individuals who are HCV+.

Association of Pelvic Organ Prolapse Quantification examination D point with uterosacral ligament suspension outcomes: the "OPTIMAL" D point.

INTRODUCTION AND HYPOTHESIS: The objective was to determine the relationship between the preoperative D-point and apical outcomes at 24 months, using the Operations and Pelvic Muscle Training in the Management of Apical Support Loss (OPTIMAL) dataset. METHODS: This was a secondary analysis of the OPTIMAL trial, a randomized multi-centered study comparing outcomes of sacrospinous ligament fixation and transvaginal uterosacral ligament suspension (USLS). The 2-year dataset utilized included women undergoing USLS with concomitant hysterectomy. The primary outcome was the relationship between preoperative D-point and apical outcomes at 24 months. Secondary objectives were to determine the relationship between preoperative D-point and anatomical, composite and subjective outcomes, and to determine a D-point cut-off that could be used to predict success in each of these categories. RESULTS: Of the 186 women in the USLS arm, 120 were available for analysis of anatomical failure at 24 months. A higher preoperative D-point correlated with improved apical outcome (C-point) at 24 months (r = 0.34; p value = 0.0002). Using ROC curves, a moderate association was found between the preoperative D-point and apical and anatomical success, (AUC 0.689 and 0.662). There was no relationship between preoperative D-point and composite or subjective success (AUC 0.577 and 0.458). Based on the ROC curves, a "cut-off" D-point value of -4.25 cm (sensitivity = 0.58, specificity = 0.67) was determined to be a predictor of postoperative anatomical success at 2 years. CONCLUSIONS: Preoperative D-point correlates with postoperative anatomical and apical support, but is less successful at predicting subjective outcomes. The strongest predictive D-point cut-off for anatomical and apical success at 24 months was -4.25 cm.

Appendiceal tumors with glandular and neuroendocrine features exhibiting peritoneal metastases - Critical evaluation of outcome following cytoreductive surgery with perioperative chemotherapy.

BACKGROUND: A rare appendiceal malignancy is characterized by both glandular and neuroendocrine histology. It often presents with dissemination of the perforated tumor to peritoneal surfaces. Current treatments involve systemic chemotherapy, cytoreductive surgery and perioperative intraperitoneal chemotherapy. METHODS: The impact of clinical, histological and treatment-related characteristics on survival were evaluated and subjected to univariate statistical analyses. All patients had stage IV disease and were treated by a uniform treatment strategy. Survival was determined from onset of disease until death or most recent follow-up. RESULTS: There were 47 patients available for study of whom 17 were male. Median age was 48 with a range of 27-65. None or a single symptom vs. 2 or more symptoms had a significant effect on survival. Median survival of the entire cohort was 45 months and 34.88% and 8.72% of patients survived 5 and 10 years, respectively. The use of neoadjuvant chemotherapy showed no impact on survival. Patients with a peritoneal cancer index (PCI) of 0-20 as compared to PCI > 20 survived longer (p = 0.012). The survival of patients able to have a complete resection as compared to an incomplete resection of disease was significant (p = 0.0087). The type of perioperative chemotherapy did not alter survival. CONCLUSIONS: These data show that patients with a lesser extent of disease with a complete cytoreduction had an improved prognosis. No benefit from systemic or perioperative regional chemotherapy was apparent. With long-term follow-up, patients with the combined glandular and neuroendocrine histology exhibiting peritoneal metastases have a guarded prognosis.

Larger patients shouldnt have fewer options: urethroplasty is safe in the obese

ABSTRACT Objective To examine the impact of obesity on perioperative outcomes and urethral stricture recurrence after anterior urethroplasty. Material and Methods We reviewed our prospectively maintained single-surgeon database to identify men with anterior urethral strictures who had undergone anastomotic or augmentation urethroplasty between October 2012 and March 2018. In all, 210 patients were included for primary analysis of perioperative outcomes, while 193 patients with at least 12 months follow-up were included for secondary analysis of stricture recurrence. Patients grouped by BMI were compared using univariate and multivariate analyses for perioperative outcomes and log rank testing for recurrence-free survival. Results Overall, 41% (n=86) of patients were obese and 58.6% (n=123) had bulbar urethral strictures. Obese patients had significantly longer urethral strictures (mean=6.7cm±4.7) than nonobese patients (p <0.001). Though urethroplasty in obese patients was associated with increased estimated blood loss (EBL) relative to normal BMI patients on both univariate (p=0.003) and multivariate (p <0.001) analyses, there was no difference in operative time, length of stay, or complication rate between BMI groups. At a mean follow-up interval of 36.7 months, 15% (n=29) of patients had stricture recurrence, yet recurrence-free survival was not significantly different between groups (log rank p=0.299). Dorsal augmentation urethroplasty resulted in significantly fewer recurrences in obese patients compared to nonobese patients (p=0.036). Conclusion Despite the association with increased urethral stricture length and EBL, obesity is not predictive of adverse perioperative outcomes or stricture recurrence. Obese patients should be offered urethral reconstruction, but patient selection and preoperative counseling remain imperative.

Lymphoma survivors have an increased long-term risk of chronic kidney disease.

With improving lymphoma survival, late effects of therapy have emerged. Here, we describe pattern of long-term chronic kidney disease (CKD) in lymphoma survivors. Demographics, comorbidities, lymphoma histology, treatment, and outcome were recorded. Glomerular filtration rate (GFR) was recorded at diagnosis, 1, 2, 5, and 10 years. Rate of GFR decline with time and CKD-free survival were recorded. In 397 patients, median age was 55.3 (18-88), 54% were male, 60% were African Americans, 42% had hypertension (HTN), 15% had DM, 13% had hyperuricemia, 86% received chemotherapy, and 14% had baseline CKD. Total 125 (31%) patients developed CKD in 10 years after lymphoma diagnosis. Probability of CKD development increased significantly with time (23% at 1 year to 41% at 10 years). Rate of GFR decline was 4.6 mL/min/per year. Age, HTN, hyperuricemia, and DM (in young patients) predicted risk of CKD. Thus, lymphoma survivors are at substantial long-term risk of CKD development.

Trends in the Use of Cardiac Imaging for Women with Newly Diagnosed Breast Cancer.

We investigated time trends and factors associated with the use of cardiac imaging among women with early-stage breast cancer prior to the initiation of treatment. Of 11,732 women ages 24-64, diagnosed with stage I-III breast cancer in 2006-2011, 2550 (22%) received anthracycline-based chemotherapy. Baseline cardiac imaging was used in 79% of patients receiving anthracyclines and increased over time. Of 2277 (20%) women who received non-anthracycline therapy, 16% received cardiac imaging. Women receiving cardiac imaging in non-anthracycline therapy group were more likely to have higher cardiovascular risk, as well as higher cancer stage and worse histological tumor grade suggesting that results of imaging might have influenced the choice of cancer therapy. Our findings indicate the need for cardio-oncology collaboration in identification and treatment of women at high risk for adverse oncology and cardiovascular outcomes.

Antibiotic Use in Hand Surgery: Surgeon Decision Making and Adherence to Available Evidence.

Background: There are no clearly defined guidelines from hand surgical societies regarding preoperative antibiotic prophylaxis. Many hand surgeons continue to routinely use preoperative prophylaxis with limited supporting evidence. This study aimed to determine for which scenarios surgeons give antibiotics, the reasons for administration, and whether these decisions are evidence-based. Methods: An anonymous 25-question survey was e-mailed to the 921-member American Society for Surgery of the Hand listserv. We collected demographic information; participants were asked whether they would administer antibiotics in a number of surgical scenarios and for what reasons. Respondents were broken into 3 groups based on when they said they would administer antibiotics: Group 1 (40 respondents) would give antibiotics in the case of short cases, healthy patients, without hardware; group 2 (9 respondents) would not give antibiotics in any scenario; and group 3 (129 respondents) would give antibiotics situationally. The Fisher exact test compared demographic variables, frequency of use, and indications of antibiotic prophylaxis. Results: Of the 921 recipients, 178 (19%) responded. Demographic variables did not correlate with the antibiotic use group. Operative case time >60 minutes, medical comorbidity, and pinning each increased antibiotic use. Group 1 respondents were more likely to admit that their practice was not evidence-based (74.4%) and that they gave antibiotics for medical-legal concern (75%). Twenty-two percent of respondents reported seeing a complication from routine prophylaxis, including Clostridium difficile infection. Conclusions: Antibiotics are still given unnecessarily before hand surgery, most often for medical-legal concern. Clear guidelines for preoperative antibiotic use may help reduce excessive and potentially inappropriate treatment and provide medical-legal support.
