A multimodal approach improves American Board of Surgery In-Training Examination scores.

Background: There are several factors that influence ABSITE scores, but the optimal approach for remediation of poor scores is unclear.

Methods: A structured academic curriculum and focused remediation program (FRP) were implemented to improve academic performances. Within a 15-year period, ABSITE and American Board of Surgery qualifying exam (ABS QE) results were compared before and after the establishment of the program using a paired T-test.

Relationships between computer-extracted mammographic texture pattern features and BRCA1/2 mutation status: a cross-sectional study.

Introduction: Mammographic density is similar among women at risk of either sporadic or BRCA1/2-related breast cancer. It has been suggested that digitized mammographic images contain computer-extractable information within the parenchymal pattern, which may contribute to distinguishing between BRCA1/2 mutation carriers and non-carriers.

Methods: We compared mammographic texture pattern features in digitized mammograms from women with deleterious BRCA1/2 mutations (n = 137) versus non-carriers (n = 100).

Breast cancer screening patterns among military beneficiaries: racial variations in screening eliminated in an equal-access model.

Background: African American women present with more aggressive breast tumors and at later stages than white women. Many factors have been proposed to explain these findings, including socioeconomic status, cultural beliefs, and access to medical care. The purpose of this project was to determine if stage at presentation would be equivalent in a system providing equal access to care and if screening was equivalent.

Thoracic gallstones: a delayed complication of laparoscopic cholecystectomy.

Background: Thoracic complications resulting from gallstone spillage during laparoscopic cholecystectomy are rare and may occur years after the index surgery. We present the case of a chronic lung abscess resulting from trans-diaphragmatic migration of gallstones spilled and "lost" during a laparoscopic cholecystectomy.

Methods: Case report and literature review.

Single-cell genetic analysis of ductal carcinoma in situ and invasive breast cancer reveals enormous tumor heterogeneity yet conserved genomic imbalances and gain of MYC during progression.

Ductal carcinoma in situ (DCIS) is a precursor lesion of invasive ductal carcinoma (IDC) of the breast. To understand the dynamics of genomic alterations in this progression, we used four multicolor fluorescence in situ hybridization probe panels consisting of the oncogenes COX2, MYC, HER2, CCND1, and ZNF217 and the tumor suppressor genes DBC2, CDH1, and TP53 to visualize copy number changes in 13 cases of synchronous DCIS and IDC based on single-cell analyses. The DCIS had a lower degree of chromosomal instability than the IDC.

A prospective model of care for breast cancer rehabilitation: postoperative and postreconstructive issues.

Appropriate and timely rehabilitation is vital in the recovery from breast cancer surgeries, including breast conserving surgery, mastectomy, axillary lymph node dissection (ALND), and breast reconstruction. This article describes the incidence, prevalence, risk factors and time course for early postoperative effects and the role of prospective surveillance as a rehabilitation strategy to prevent and mitigate them. The most common early postoperative effects include wound issues such as cellulitis, flap necrosis, abscess, dehiscence, hematoma, and seroma.

A prospective surveillance model for rehabilitation for women with breast cancer.

Background: The current model of care for individuals with breast cancer focuses on treatment of the disease, followed by ongoing surveillance to detect recurrence. This approach lacks attention to patients' physical and functional well-being. Breast cancer treatment sequelae can lead to physical impairments and functional limitations.

Racial disparities in physical and functional domains in women with breast cancer.

Introduction: African-American women are more likely than white women to have functional impairments after breast cancer (BC) surgery; however, no differences were found in self-reported health status surveys at 12+ months postsurgery.

Purpose: This analysis compared white and African-American BC survivors' (BCS) health status, health-related quality of life, and the occurrence of physical impairments after BC treatment.

Methods: One hundred sixty-six women (130 white, 28 African-American, 8 other) were assessed for impairments preoperatively and at 1, 3, 6, 9, and 12+ months postsurgery.

Segmental limb volume change as a predictor of the onset of lymphedema in women with early breast cancer.

Objective: To demonstrate that segmental changes along the upper extremity occur before the onset of breast cancer-related lymphedema (BCRL). These changes may be subclinical in nature and may be predictive of the onset of chronic lymphedema.

Design: A retrospective subset analysis of a larger prospective cohort trial.

Breast cancer-related lymphedema: comparing direct costs of a prospective surveillance model and a traditional model of care.

Secondary prevention involves monitoring and screening to prevent negative sequelae from chronic diseases such as cancer. Breast cancer treatment sequelae, such as lymphedema, may occur early or late and often negatively affect function. Secondary prevention through prospective physical therapy surveillance aids in early identification and treatment of breast cancer-related lymphedema (BCRL).

Factors predicting clinically significant fatigue in women following treatment for primary breast cancer.

Cancer-related fatigue is common, complex, and distressing. It affects 70-100% of patients receiving chemotherapy and a significant number who have completed their treatments. We assessed a number of variables in women newly diagnosed with primary breast cancer (BrCa) to determine whether biological and/or functional measures are likely to be associated with the development of clinically significant fatigue (CSF).

Axillary sentinel lymph node biopsy after mastectomy: a case report.

Background: Sentinel lymph node biopsy has been established as the preferred method for staging early breast cancer. A prior history of mastectomy is felt to be a contraindication.

Case Presentation: A patient with recurrent breast cancer in her skin flap was discovered to have positive axillary sentinel nodes by sentinel lymph node biopsy five years after mastectomy for ductal carcinoma in situ.

Mammographic density does not differ between unaffected BRCA1/2 mutation carriers and women at low-to-average risk of breast cancer.

Elevated mammographic density (MD) is one of the strongest risk factors for sporadic breast cancer. Epidemiologic evidence suggests that MD is, in part, genetically determined; however, the relationship between MD and BRCA1/2 mutation status is equivocal. We compared MD in unaffected BRCA1/2 mutation carriers enrolled in the U.

Pre-operative assessment enables early diagnosis and recovery of shoulder function in patients with breast cancer.

In order to determine the extent and time course of upper limb impairment and dysfunction in women being treated for breast cancer (BC), and followed prospectively, a novel physical therapy surveillance model post-treatment was used. Subjects included adult women with newly diagnosed, untreated, unilateral, Stage I to III BC, and normal physiological and biomechanical shoulder function. Subjects were excluded if they had a previous history of BC, or prior injury or surgery of the affected upper limb.

The influence of a gene expression profile on breast cancer decisions.

Purpose: The Oncotype Dx Recurrence Score (RS), is often employed in patients with estrogen receptor-positive, node negative (ER+LN-) breast cancer. We investigated the impact of the RS on actual chemotherapy administration and the effect of the assay on a panel of breast oncology experts.

Patients And Methods: The prospective adjuvant chemotherapy recommendations (prior to RS) and actual adjuvant therapy (after RS) for consecutive patients with ER+LN- breast cancer were recorded.

Genetic testing for cancer susceptibility.

Genetic testing for mutations in genes associated with an inherited predisposition to cancer is rapidly moving outside specialty genetic services and into mainstream health care. Surgeons, as front-line providers of cancer care, are uniquely positioned to identify those who may benefit from genetic testing and institute changes to their health care management based on those results. This article provides an overview of the critical elements of the process of genetic testing for cancer susceptibility.

Preoperative assessment enables the early diagnosis and successful treatment of lymphedema.

Background: The incidence of breast cancer (BC)-related lymphedema (LE) ranges from 7% to 47%. Successful management of LE relies on early diagnosis using sensitive measurement techniques. In the current study, the authors demonstrated the effectiveness of a surveillance program that included preoperative limb volume measurement and interval postoperative follow-up to detect and treat subclinical LE.

Perceptions of cancer risks and predictors of colon and endometrial cancer screening in women undergoing genetic testing for Lynch syndrome.

Purpose: Lynch syndrome poses multiple cancer risks, yet attention has focused on screening for colorectal cancer. Estimated risks for endometrial cancer equal risks for colorectal cancer. This study (1) evaluated women's perceived risks for cancers, (2) compared endometrial cancer screening and colonoscopy, and (3) identified predictors of screening before and after genetic testing.

Randomized comparison of phone versus in-person BRCA1/2 predisposition genetic test result disclosure counseling.

Purpose: This study evaluated whether phone results were equivalent to in-person result disclosure for individuals undergoing BRCA1/2 predisposition genetic testing.

Methods: A total of 111 of 136 subjects undergoing education and counseling for BRCA1/2 predisposition genetic testing agreed to randomization to phone or in-person result disclosure. Content and format for both sessions were standardized.

Gene expression patterns distinguish colonoscopically isolated human aberrant crypt foci from normal colonic mucosa.

Aberrant crypt foci (ACF) are considered the earliest identifiable preneoplastic colonic lesions; thus, a greater understanding of the nature of genetic changes underlying the transformation of normal colonic mucosa (NM) into ACF may provide insight into the mechanisms of carcinogenesis. ACF were identified by indigo carmine spraying onto colonic mucosa during colonoscopy and isolated as standard pinch biopsies of the mucosal areas containing the ACF. RNAs isolated from ACF and matched NM biopsies from the ascending and descending colons of 13 patients were analyzed on arrays containing 9128 cDNAs.

Celecoxib treatment alters the gene expression profile of normal colonic mucosa.

A clinical trial was recently conducted to evaluate the safety and efficacy of a selective inhibitor of cyclooxygenase-2 (celecoxib) in hereditary nonpolyposis colon cancer patients. In a randomized, placebo-controlled phase I/II multicenter trial, hereditary nonpolyposis colon cancer patients and gene carriers received either celecoxib at one of two doses or placebo. The goal was to evaluate the effects of these treatment arms on a number of endoscopic and tissue-based biomarker end points after 12 months of treatment.

Randomized comparison of group versus individual genetic education and counseling for familial breast and/or ovarian cancer.

Purpose: An efficient approach to education and counseling before BRCA1 and BRCA2 mutation testing is necessary for effective utilization of testing in the community. Education and counseling, when delivered individually, are limited by a shortage of trained health care providers as well as by financial and time constraints. The purpose of this study was to determine whether pretest education and counseling for breast cancer genetics in a group setting is equivalent to that provided on an individual basis.

Subcutaneous PO2 as an index of the physiological limits for hemodilution in the rat.

This study was designed to test the hypothesis that changes in subcutaneous PO2 (PscO2) during progressive hemodilution will reliably predict a "critical point" at which tissue O2 consumption (VO2) becomes dependent on O2 delivery (QO2). Twelve pentobarbital-anesthetized male Sprague-Dawley rats (315-375 g) underwent stepwise exchange of plasma for blood (1.5 ml of plasma for each 1 ml of blood lost).
