RESUMO
INTRODUCTION: Breast cancer is the most diagnosed cancer among Mongolian women and mortality rates are high. We describe a virtual multi-institutional and multidisciplinary tumor board (MTB) for breast cancer created to assist the National Cancer Center of Mongolia. MATERIALS AND METHODS: A virtual MTB for breast cancer was conducted with participation of two United States and 1 Mongolian cancer centers. A standardized template for presentations was developed. Recommendations were summarized and shared with participants. Collected data included patient demographics, tumor characteristics, stage, imaging and treatments performed, and recommendations. Questions were categorized as treatment, diagnosis, or palliative questions. RESULTS: Fifteen patients were evaluated. Median age was 39 y. 86.7% of breast cancers were invasive ductal cancers and 13.3% were metaplastic carcinomas. 53.3% were estrogen and progesterone receptor positive (ER+/PR+), 60% were HER2+, 13.3% were triple negative, and 26.7% were recurrent. 40% of patients were evaluated with mammography. 6% received positron emission tomography scans for metastatic evaluation. 66.7% of surgical patients received neoadjuvant chemotherapy. Herceptin was administered to 55.6% of patients with Her2+ cancers. Modified radical mastectomy was most commonly performed and reconstruction was rare. Sentinel lymph node biopsy was not performed. 66.7% of ER+/PR+ patients received endocrine therapy. 6.7% of patients received radiation. 75% of MTB questions pertained to treatment. Recommendations were related to systemic therapy (40%), surgical management (33.3%), pathology (13.3%), and imaging (13.3%). CONCLUSIONS: This study illustrates the development of an international, virtual, multi-institutional breast cancer MTB and provides insight into challenges and potential interventions to improve breast cancer care in Mongolia.

BACKGROUND. PET/CT with 18F-fluoroestradiol (FES) (FDA-approved in 2020) depicts tissues expressing estrogen receptor (ER). Invasive lobular carcinoma (ILC) is commonly ER positive. OBJECTIVE. The primary aim of this study was to assess the frequency with which sites of histologically proven ILC have abnormal uptake on FES PET/CT. METHODS. This prospective single-center pilot study, conducted from December 2020 to August 2021, enrolled patients with histologically confirmed ILC to undergo FES PET/CT; patients optionally underwent FDG PET/CT. Two nuclear radiologists assessed FES PET/CT and FDG PET/CT studies for abnormal uptake corresponding to known ILC sites at enrollment and for additional sites of abnormal uptake, resolving differences by consensus. The primary endpoint was percentage of known ILC sites showing abnormal FES uptake. The alternative to the null hypothesis was that more than 60% of sites would have abnormal FES uptake, exceeding the percentage of ILC with abnormal FDG uptake described in prior literature. A sample size of 24 biopsied lesions was preselected to provide 81% power for the alternative hypothesis (one-sided α = .10). Findings on FES PET/CT and FDG PET/CT were summarized for additional secondary endpoints. RESULTS. The final analysis included 17 patients (mean age, 59.1 ± 13.2 years) with 25 sites of histologically confirmed ILC at enrollment (22 breast lesions, two axillary lymph nodes, one distant metastasis). FES PET/CT showed abnormal uptake in 22 of 25 (88%) lesions, sufficient to reject the null hypothesis (p = .002). Thirteen patients underwent FDG PET/CT. Four of 23 (17%) sites of histologically confirmed ILC, including additional sites detected and confirmed after enrollment, were identified with FES PET/CT only, and 1 of 23 (4%) was identified only with FDG PET/CT (p = .18). FES PET/CT depicted additional lesions not detected with standard-of-care evaluation in 4 of 17 (24%) patients (two contralateral breast cancers and two metastatic axillary lymph nodes, all with subsequent histologic confirmation). Use of FES PET/CT resulted in changes in clinical stage with respect to standard-of-care evaluation in 3 of 17 (18%) patients. CONCLUSION. The primary endpoint of the trial was met. The frequency of abnormal FES uptake among sites of histologically known ILC was found to be to be significantly greater than 60%. CLINICAL IMPACT. This pilot study shows a potential role of FES PET/CT in evaluation of patients with ILC. TRIAL REGISTRATION. ClinicalTrials.gov NCT04252859.

BACKGROUND: The Gambia has one of the lowest survival rates for breast cancer in Africa. Contributing factors are late presentation, delays within the healthcare system, and decreased availability of resources. We aimed to characterize the capacity and geographic location of healthcare facilities in the country and calculate the proportion of the population with access to breast cancer care. METHODS: A facility-based assessment tool was administered to secondary and tertiary healthcare facilities and private medical centers and clinics in The Gambia. GPS coordinates were obtained, and proximity of service availability and population analysis were performed. Distance thresholds of 10, 20, and 45 km were chosen to determine access to screening, pathologic diagnosis, and surgical management. An additional population analysis was performed to observe the potential impact of targeted development of resources for breast cancer care. RESULTS: All 102 secondary and tertiary healthcare facilities and private medical centers and clinics in The Gambia were included. Breast cancer screening is mainly performed through clinical breast examination and is available in 52 facilities. Seven facilities provide pathologic diagnosis and surgical management of breast cancer. The proportion of the Gambian population with access to screening, pathologic diagnosis, and surgical management is 72, 53, and 62%, respectively. A hypothetical targeted expansion of resources would increase the covered population to 95, 62, and 84%. CONCLUSIONS: Almost half of the Gambian population does not have access to pathologic diagnosis and surgical management of breast cancer within the distance threshold utilized in the study. Mapping and population analysis can identify areas for targeted development of resources to increase access to breast cancer care.

BACKGROUND: An arteriovenous fistula (AVF) exposes the outflow vein to arterial magnitudes and frequencies of blood pressure and flow, triggering molecular pathways that result in venous remodeling and AVF maturation. It is unknown, however, how venous remodeling, that is lumen dilation and wall thickening, affects venous mechanical properties. We hypothesized that a fistula is more compliant compared with a vein because of altered contributions of collagen and elastin to the mechanical properties. METHODS: Ephb4+/- and littermate wild-type (WT) male mice were treated with sham surgery or needle puncture to create an abdominal aortocaval fistulae. The thoracic inferior vena cava was harvested 3 wk postoperatively for mechanical testing and histological analyses of collagen and elastin. RESULTS: Mechanical testing of the thoracic inferior vena cava from Ephb4+/- and WT mice showed increased distensibility and increased compliance of downstream veins after AVF compared with sham. Although Ephb4+/- veins were thicker than WT veins at the baseline, after AVF, both Ephb4+/- and WT veins showed similar wall thickness as well as similar collagen and elastin area fractions, but increased collagen undulation compared with sham. CONCLUSIONS: Fistula-induced remodeling of the outflow vein results in circumferentially increased distensibility and compliance, likely due to post-translational modifications to collagen.

BACKGROUND: There exists a dogma of surgical nihilism for patients with cirrhosis and breast cancer causing de-escalation of surgery and impacting survival. We hypothesized that breast cancer surgery would not result in a significant change in the Model for End-Stage Liver Disease-Sodium (MELD-Na) scores before and after surgery. METHODS: We performed a single institutional retrospective review of medical records between January 2013 and July 2019 of patients with concurrent cirrhosis and breast cancer. We used the nonparametric Friedman test to compare differences in MELD-Na scores. RESULTS: Eight patients with both cirrhosis and breast cancer were identified. Median follow-up was 30.5 mo. Half of the patients had Child-Pugh class A cirrhosis and half had Child-Pugh class B cirrhosis. Six (75%) patients underwent lumpectomy and two (25%) underwent mastectomy. There was no statistically significant difference (P = 0.66) in median MELD-Na score before surgery (16) and after surgery (18). Two (25%) patients experienced postoperative complications. Three patients were listed for liver transplantation. Of three listed patients, two (25%) patients underwent successful liver transplantation after breast surgery. One (12.5%) patient died without transplant. Three (37.5%) patients were alive for more than 5 y after breast cancer diagnosis without evidence of cancer recurrence. The eighth patient has remained breast cancer free for more than 6 mo since her surgery. CONCLUSIONS: Surgery for patients with Child-Pugh class A and B cirrhosis and early stage breast cancer did not result in a significant change in MELD-Na score before and after surgery, suggesting that selected patients may benefit from breast cancer surgery with curative intent.

Gallbladder agenesis (GA) is an extremely rare congenital entity. The incidence is around 1 per 6500 live births. The majority of patients, estimated between 50 to 70 percent, remain asymptomatic while those who are symptomatic report symptoms mimicking biliary colic. Initial workup for suspected gallbladder pathology such as right upper quadrant ultrasound (US) can be misleading or inconclusive. Furthermore, advanced diagnostic studies such as hepatobiliary iminodiacetic acid (HIDA) scan and endoscopic retrograde cholangio-pancreatography (ERCP) may report non-visualization of the gallbladder and erroneously lead providers to a diagnosis of cystic duct obstruction rather than GA. Consequently, some GA patients are only finally diagnosed intraoperatively. Surgery can be risky in these patients because unnecessary dissection while looking for the non-existent gallbladder can result in injury of the biliary tree, hepatic vasculature, or small bowel. Therefore, clinicians should keep GA on their differential diagnosis list and imaging modalities such as magnetic resonance cholangiopancreatography (MRCP) should be obtained when other tests prove inconclusive. We report a 35-year-old female presenting with chronic symptoms consistent with biliary colic and an equivocal US reported as cholelithiasis. She underwent laparoscopy during which the absence of the gallbladder was noted. Postoperative MRCP confirmed the diagnosis of GA.

BACKGROUND: Pretreatment with antibiotics is commonly performed before surgical implantation of prosthetic materials. We previously showed that pericardial patches are infiltrated by macrophages and arterial stem cells after implantation into an artery. We hypothesized that antibiotic pretreatment would diminish the number of cells infiltrating into the patch, potentially affecting early neointimal formation. METHODS: Bovine pericardial patches were pretreated with saline, bacitracin (500 U/mL), or cephalexin (10 mg/mL) for 30 minutes before implantation into the Wistar rat infrarenal aorta. Patches were retrieved on day 7 or day 30 and analyzed for histology and cell infiltration. Markers of proliferation, apoptosis, vascular cell identity, and M1 and M2 macrophage subtypes were examined using immunofluorescence and immunohistochemistry. Extracted proteins were analyzed by Western blot. RESULTS: At day 7, pericardial patches pretreated with bacitracin or cephalexin showed similar amounts of neointimal thickening (P = .55) and cellular infiltration (P = .42) compared with control patches. Patches pretreated with antibiotics showed similar proliferation (P = .09) and apoptosis (P = .84) as control patches. The cell composition of the neointima in pretreated patches was similar to control patches, with a thin endothelial layer overlying a thin layer of smooth muscle cells (P = .45), and containing similar numbers of CD34-positive (P = .26) and vascular endothelial growth factor receptor 2-positive (P = .31) cells. Interestingly, within the body of the patch, there were fewer macrophages (P = .0003) and a trend towards fewer endothelial progenitor cells (P = .051). No M1 macrophages were found in or around any of the patches. M2 macrophages were present around the patches, and there was no difference in numbers of M2 macrophages surrounding control patches and patches pretreated with antibiotics (P = .24). There was no difference in neointimal thickness at day 30 between control patches and patches pretreated with antibiotics (P = .52). CONCLUSIONS: Pretreatment of bovine pericardial patches with the antibiotics bacitracin or cephalexin has no detrimental effect on early patch healing, with similar neointimal thickness, cellular infiltration, and numbers of M2 macrophages compared with control patches. These results suggest that the host vessel response to patch angioplasty using pericardial patches is adaptive remodeling (eg, arterial healing).

BACKGROUND: Endovascular angioplasty and stent placement is currently the most frequent treatment for iliac artery occlusive disease. However, despite a successful endovascular procedure, some patients do not experience symptomatic improvement and satisfaction with their care. This study seeks to identify patient-related factors associated with lack of symptomatic improvement after endovascular iliac artery treatment in male veterans. METHODS: Retrospective review of patients treated with endovascular methods for iliac artery occlusive disease between January 2008 and July 2012 at VA Connecticut Healthcare System. Symptomatic improvement on the first post-operative visit was evaluated, with bilateral treatments counted separately. RESULTS: Sixty-two patients had 91 iliac arteries treated with angioplasty and stent placement. Forty-seven (52 percent) legs had critical limb ischemia, and 77 (85 percent) had at least two-vessel distal runoff. Angiographic success was 100 percent. Patient-reported symptomatic improvement at the first post-operative visit was 55 percent (50/91). Lack of symptomatic improvement correlated with older age (OR 1.09 [1.03-1.17], p = 0.008), presence of critical limb ischemia (OR 3.03 [1.09-8.65], p = 0.034), and need for additional surgical intervention (OR 5.61 [1.65-17.36], p = 0.006). Survival, primary and secondary patency, and freedom from restenosis were comparable between patients who reported symptomatic improvement and those who did not. CONCLUSIONS: Despite angiographically successful revascularization, patients who are older or have critical limb ischemia who are treated with isolated endovascular iliac artery intervention are more likely to require additional interventions and less likely to experience symptomatic improvement. These patients may need more extensive infra-inguinal revascularization than isolated iliac angioplasty and stent placement, despite a preserved ankle-brachial index. Quality of life needs to be measured with formal instruments after iliac artery endovascular treatment, especially to determine long term outcomes.

PURPOSE: Breast cancer is the most frequent cancer and second most common cause of cancer-related death in Ghana. Early detection and access to diagnostic services are vital for early treatment initiation and improved survival. This study characterizes the geographic access to hospital-based breast cancer diagnostic services in Ghana as a framework for expansion. METHODS: A cross-sectional hospital-based survey was completed in Ghana from November 2020 to October 2021. Early diagnostic services, as defined by the National Comprehensive Cancer Network (NCCN) Framework for Resource Stratification, was assessed at each hospital. Services were characterized as available >80% of the time in the previous year, <80%, or not available. ArcGIS was used to identify the proportion of the population within 20 and 45 km of services. RESULTS: Most hospitals in Ghana participated in this survey (95%; 328 of 346). Of these, 12 met full NCCN Basic criteria >80% of the time, with 43% of the population living within 45 km. Ten of the 12 met full NCCN Core criteria, and none met full NCCN Enhanced criteria. An additional 12 hospitals were identified that provide the majority of NCCN Basic services but lack select services necessary to meet this criterion. Expansion of services in these hospitals could result in an additional 20% of the population having access to NCCN Basic-level early diagnostic services within 45 km. CONCLUSION: Hospital-based services for breast cancer early diagnosis in Ghana are available but sparse. Many hospitals offer fragmented aspects of care, but only a limited number of hospitals offer the full NCCN Basic or Core level of care. Understanding current availability and geographical distribution of services provides a framework for potential targeted expansion of services.

PURPOSE: Assessing risk of recurrence for nonmetastatic triple-negative breast cancer (TNBC) is a key determinant of therapeutic strategy. The best predictor of recurrence risk is failure to achieve a pathologic complete response after preoperative chemotherapy, but it imperfectly correlates with the definitive end points of relapse-free and overall survival (OS). The inability to accurately predict recurrence has led to increasingly toxic treatment regimens for patients with early-stage TNBC. Better assays for recurrence risk are needed to tailor aggressive therapy for patients who need it and avoid overtreatment and unnecessary toxicity for those at low risk. The purpose of this study was to determine if patient-derived xenograft (PDX) engraftment of newly diagnosed breast tumors can serve as an accurate predictor of recurrence and death from breast cancer. METHODS: This study was a blinded noninterventional trial comprising 80 patients with newly diagnosed, nonmetastatic, estrogen receptor (ER)-negative or ER-low breast cancer. RESULTS: PDX engraftment was strongly associated with relapse in 1 year: 8 of 18 (44.4%) patients whose tumors engrafted relapsed versus 1 of 62 (1.6%) patients whose tumors did not engraft (P < .0001). Patients whose tumors engrafted had a hazard ratio (HR) for relapse of 17.5. HRs for OS and breast cancer-specific survival in PDX+ patients were 21.1 and 39.5, respectively. CONCLUSION: We report that the ability of a tumor to engraft as a PDX predicts early recurrence by serving as a functional readout of aggressiveness and prospectively identifies the most devastating tumors. This provides new opportunity to develop surrogate assays, such as biomarkers of engraftment, which will extend the clinical feasibility of this finding.

Background: Palpable ductal carcinoma in-situ (pDCIS) is a subset of DCIS presenting with a clinical mass. We hypothesized pDCIS would have more aggressive clinical and pathological features, and higher rates of recurrence and upgrade to invasive disease compared to screen-detected DCIS. Materials and methods: We performed a retrospective analysis of female patients (age 28-76) with DCIS on core-needle biopsy. pDCIS patients had a physician documented palpable mass prior to initial biopsy. Descriptive statistics were performed to compare groups. Results: This study included 83 patients, 26 had pDCIS and 57 had screen-detected DCIS. Mean duration of follow-up was 49.4 months. pDCIS patients had significantly larger lesions (p = 0.03) which were more frequently biopsied via ultrasound (p = 0.002). In multivariate analysis, pDCIS was associated with ultrasound guided core needle biopsy, size of DCIS >2 cm, and comedo pattern (p = 0.001, p = 0.007 and p = 0.022, respectively). 7.7 % of pDCIS cases versus 3.5 % of screen-detected cases were upgraded to invasive cancer (p = 0.59). There was no difference in local recurrence (p = 0.55) between groups. Neither group experienced regional or distant recurrence. Conclusions: pDCIS was associated with some aggressive pathologic and clinical features and was more frequently diagnosed by ultrasound guided core-needle biopsy than screen-detected DCIS. However, there was no significant difference in rate of recurrence or upgrade to invasive disease between groups. Key message: Although pDCIS was associated with some aggressive pathologic and clinical features, there was no significant difference in rate of recurrence or upgrade to invasive disease compared to screen-detected DCIS.
RESUMO
Breast cancer in Ghana is a growing public health problem with increasing incidence and poor outcomes. Lack of access to comprehensive treatment in Ghana may be a contributing factor to its high mortality. The purpose of this study was to evaluate the availability of treatments nationwide and systematically identify high yield areas for targeted expansion. We conducted a cross-sectional, nationwide hospital-based survey from November 2020-October 2021. Surveys were conducted in person with trained research assistants and described hospital availability of all breast cancer treatments and personnel. All individual treatment services were reported, and hospitals were further stratified into levels of multi-modal treatment modeled after the National Comprehensive Cancer Network (NCCN) Framework treatment recommendations for low-resource settings. Level 3 included Tamoxifen and surgery (mastectomy with axillary lymph node sampling); Level 2 included Level 3 plus radiation, aromatase inhibitors, lumpectomy, and sentinel lymph node biopsy; Level 1 included Level 2 plus Her2 therapy and breast reconstruction. Hospitals were identified that could expand to these service levels based on existing services, location and personnel. The distance of the total population from treatment services before and after hypothetical expansion was determined with a geospatial analysis. Of the 328 participating hospitals (95% response rate), 9 hospitals had Level 3 care, 0 had Level 2, and 2 had Level 1. Twelve hospitals could expand to Level 3, 1 could expand to Level 2, and 1 could expand to Level 1. With expansion, the population percentage within 75km of Level 1, 2 and 3 care would increase from 42% to 50%, 0 to 6% and 44% to 67%, respectively. Multi-modal breast cancer treatment is available in Ghana, but it is not accessible to most of the population. Leveraging the knowledge of current resources and population proximity provides an opportunity to identify high-yield areas for targeted expansion.

BACKGROUND: Transitioning from trainee to attending surgeon requires learners to become educators. The purpose of this study is to evaluate educational strategies utilized by surgeons, define gaps in preparation for operative teaching, and identify opportunities to support this transition. METHODS: A web-based, Association of Surgical Education approved survey was distributed to attending surgeons. RESULTS: There were 153 respondents. Narrating actions was the most frequently reported educational model, utilized by 74% of junior faculty [JF] (0-5yrs) and 63% of senior faculty [SF] (>6yrs). Other models used included educational time-outs (29% JF, 27% SF), BID teaching model (36% JF, 51% SF), and Zwisch model (13% JF, 25% SF). Compared with 91% JF, 65% SF reported struggling with instruction (p < 0.001). Five themes emerged as presenting difficulty during the resident to attending transition: lack of relationships, ongoing learning, systems-based, cognitive load, impression management. CONCLUSIONS: Our results represent a needs assessment in the transition from learner to educator in the OR.

Granulomatous lobular mastitis (GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence. Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions, etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology. The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidence-based consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.

OBJECTIVES: Define the services available for the care of breast cancer at hospitals in the Eastern Region of Ghana, identify areas of the region with limited access to care through geospatial mapping, and test a novel survey instrument in anticipation of a nationwide scale up of the study. DESIGN: A cross-sectional, facility-based survey study. SETTING: This study was conducted at 33 of the 34 hospitals in the Eastern Region of Ghana from March 2020 to May 2020. PARTICIPANTS: The 33 hospitals surveyed represented 97% of all hospitals in the region. This included private, government, quasi-government and faith-based organisation owned hospitals. RESULTS: Sixteen hospitals (82%) surveyed provided basic screening services, 11 (33%) provided pathological diagnosis and 3 (9%) provided those services in addition to basic surgical care.53%, 64% and 78% of the population lived within 10 km, 25 km and 45 km of screening, diagnostic and treatment services respectively. Limited chemotherapy was available at two hospitals (6%), endocrine therapy at one hospital (3%) and radiotherapy was not available. Twenty-nine hospitals (88%) employed a general practitioner and 13 (39%) employed a surgeon. Oncology specialists, pathology personnel and a plastic surgeon were only available in one hospital (3%) in the Eastern Region. CONCLUSIONS: Although 16 hospitals (82%) provided screening, only half the population lived within reasonable distance of these services. Few hospitals offered diagnosis and surgical services, but 64% and 78% of the population lived within a reasonable distance of these hospitals. Geospatial analysis suggested two priorities to cost-effectively expand breast cancer services: (1) increase the number of health facilities providing screening services and (2) centralise basic imaging, pathological and surgical services at targeted hospitals.

We examined the efficacy of corticosteroid injection as treatment for postarthroplasty trochanteric bursitis and the risk factors for failure of nonoperative treatment. There were 32 (4.6%) cases of postsurgical trochanteric bursitis in 689 primary total hip arthroplasties. Of the 25 hips with follow-up, 11 (45%) required multiple injections. Symptoms resolved in 20 (80%) but persisted in 5. We found no statistically significant differences between patients who did and did not develop trochanteric bursitis, or between those who did and did not respond to treatment. There was a trend toward younger age and greater limb-length discrepancy in nonresponders. In conclusion, (1) corticosteroid injection(s) for postoperative trochanteric bursitis is effective; and (2) nonoperative management may be more likely to fail in young patients and those with leg-length discrepancy.

OBJECTIVE: Statin therapy has been associated with a decreased incidence of venous thromboembolism (VTE) in clinical trials and enhanced thrombus resolution in animal models. The effect of statins on thrombus resolution has not been reported clinically. This study investigates the association of statins with thrombus resolution or improvement in patients with deep venous thrombosis (DVT). METHODS: A retrospective study of the electronic medical records of consecutive adult patients presenting with lower extremity DVT was performed. Patients were divided into two groups based on statin therapy (statin group) or lack thereof (nonstatin group). The two groups were compared with respect to demographics, comorbidities, and risk factors for VTE. Initial as well as all subsequent ultrasound reports were reviewed for each patient to determine extent of DVT and subsequent change in thrombus characteristics. Long-term outcomes examined were mortality, VTE recurrence, and thrombus improvement or resolution on follow-up ultrasound examination. Multivariable analysis was used to determine independent predictors of thrombus resolution or improvement, VTE recurrence, and mortality. RESULTS: A total of 818 patients with DVT were identified (statin group, n = 279 [34%]; nonstatin group, n = 539 [66%]). The patients in the statin group were significantly older (P < .001). Patients on statins were more likely to have risk factors for and manifestations of atherosclerosis and to be on antiplatelet therapy (P < .001), whereas those in the nonstatin group were more likely to have a hypercoagulable disorder (P = .009) or prior DVT (P = .033). There was no significant difference in provoked DVT, extent of DVT, or association with pulmonary embolism (PE), but patients on statins were more likely to have high-risk PE (P = .046). There was no difference in patients receiving anticoagulation, type and duration of anticoagulation, inferior vena cava filter placement, or treatment with lytic therapy. There was no difference in thrombus resolution, mortality, or recurrence of DVT, PE, or VTE between the groups. On multivariable analysis, age, proximal DVT, CAD, and cancer were associated with higher mortality, whereas anticoagulation with coumadin and direct oral anticoagulants and antiplatelet therapy were associated with lower mortality. Statin therapy, antiplatelet therapy, and younger age were associated with thrombus resolution or improvement. CONCLUSIONS: Statin therapy is associated with greater thrombus resolution or improvement in patients with DVT. However, statin therapy in this study was not associated with different clinical outcomes of VTE recurrence or mortality.

OBJECTIVE: Provoked deep venous thrombosis (DVT) is precipitated by a specific event. This paper compares the characteristics of provoked DVT in patients with transient risk (TR) factors and patients with continuous risk (CR) factors. METHODS: A retrospective review of records of all consecutive patients diagnosed with DVT between January 2013 and August 2014 was performed. Patients with provoked DVT were included in the TR group if the provoking event resolved in 2 weeks and they did not have ongoing risk of thrombosis. Patients in the CR group had a provoked DVT with ongoing risk of thrombosis due to individual factors deemed to be ongoing risks of thrombosis, such as cancer, hypercoagulable disorder, and prolonged immobilization. Demographics, risk factors, association with pulmonary embolism (PE) and its severity, risk of recurrent venous thromboembolism (VTE), and mortality were compared between the two groups. RESULTS: A total of 838 patients were diagnosed with DVT, and 50.7% (425) were provoked. There were 127 (29.9%) patients with TR and 298 (70.1%) with CR. TR patients were younger (60.4 ± 16.3 vs 65.9 ± 16.0; P = .001). TR was more likely to be provoked by surgery (70.9% vs 55.4%; P = .003), whereas CR was more likely to be provoked by immobilization (21.5% vs 12.6%; P = .032). CR patients were affected by cancer (48.7%) and hypercoagulable disorders (4.4%). TR patients were more likely to have calf DVTs (36.2% vs 26.2%; P = .047). There was a trend toward lower association with PE on presentation in TR (17.3% vs 21.1%; P = .072), but that did not reach statistical significance. However, TR factors were more likely to be associated with low-risk PE compared with CR factors (30.2% vs 54.6%; P = .040). After mean follow-up of 7.2 months, CR had higher risk of recurrent VTE (14.0% vs 6.8%; P = .045) and mortality (23.5% vs 7.1%; P < .0001). CONCLUSIONS: Provoked DVT with CR factors affects older patients and is associated with high recurrence of VTE and mortality compared with provoked DVT with TR factors.
