RESUMO

Obesity is associated with an increased risk of, and a poor prognosis for, postmenopausal (PM) breast cancer (BC). Our goal was to determine whether diet-induced obesity (DIO) promotes 1) shorter tumor latency, 2) an escape from tumor dormancy, and 3) an acceleration of tumor growth and to elucidate the underlying mechanism(s). We have developed in vitro assays and PM breast tumor models complemented by a noninvasive imaging system to detect vascular invasion of dormant tumors and have used them to determine whether obesity promotes the escape from breast tumor dormancy and tumor growth by facilitating the switch to the vascular phenotype (SVP) in PM BC. Obese mice had significantly higher tumor frequency, higher tumor volume, and lower overall survival compared with lean mice. We demonstrate that DIO exacerbates mammary gland hyperplasia and neoplasia, reduces tumor latency, and increases tumor frequency via an earlier acquisition of the SVP. DIO establishes a local and systemic proangiogenic and inflammatory environment via the up-regulation of lipocalin-2 (LCN2), vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) that may promote the escape from tumor dormancy and tumor progression. In addition, we show that targeting neovascularization via a multitargeted receptor tyrosine kinase inhibitor, sunitinib, can delay the acquisition of the SVP, thereby prolonging tumor latency, reducing tumor frequency, and increasing tumor-free survival, suggesting that targeting neovascularization may be a potential therapeutic strategy in obesity-associated PM BC progression. This study establishes the link between obesity and PM BC and, for the first time to our knowledge, bridges the dysfunctional neovascularization of obesity with the earliest stages of tumor development.

RESUMO

INTRODUCTION: Lung cancer is consistently the leading cause of cancer death among women in the United States, yet lung cancer screening (LCS) rates remain low. By contrast, screening mammography rates are reliably high, suggesting that screening mammography can be a "teachable moment" to increase LCS uptake among dual-eligible women. MATERIALS AND METHODS: This is a prospective survey study conducted at two academic institutions. Patients undergoing screening mammography were evaluated for LCS eligibility and offered enrollment in a pilot dual-cancer screening program. A series of surveys was administered to characterize participants' knowledge, perceptions, and attitudes about LCS before and after undergoing dual screening. Data were descriptively summarized. RESULTS: Between August 2022 and July 2023, 54 LCS-eligible patients were enrolled. The study cohort was 100% female and predominantly White (81%), with a median age of 57 y and median of 36 pack-y of smoking. Survey results showed that 98% felt they were at risk for lung cancer, with most (80%) motivated by early detection of potential cancer. Regarding screening barriers, 58% of patients lacked knowledge about LCS eligibility and 47% reported concerns about screening cost. Prior to undergoing LCS, 87% of patients expressed interest in combined breast and lung screening. Encouragingly, after LCS, 84% were likely or very likely to undergo dual screening again and 93% found the shared decision-making visit helpful or very helpful. CONCLUSIONS: Pairing breast and LCS is a feasible, acceptable intervention that, along with increasing patient and provider education about LCS, can increase LCS uptake and reduce lung cancer mortality.

RESUMO

Lobular neoplasia (LN) involves proliferative changes within the breast lobules. LN is divided into lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH). LCIS can be further subdivided into three subtypes: classic LCIS, pleomorphic LCIS, and LCIS with necrosis (florid type). Because classic LCIS is now considered as a benign etiology, current guidelines recommend close follow-up with imaging versus surgical excision. The goal of our study was to determine if the diagnosis of classic LN on core needle biopsy (CNB) merits surgical excision. This is a retrospective, observational study conducted at Mount Auburn Hospital, Cambridge, MA, from May 17, 2017, through June 30, 2020. We reviewed the data of breast biopsies conducted at our hospital over this period and included patients who were diagnosed with classic LN (LCIS and/or ALH) and excluded patients having any other atypical lesions on CNB. All known cancer patients were excluded. Of the 2707 CNBs performed during the study period, we identified 68 women who were diagnosed with ALH or LCIS on CNB. CNB was performed for an abnormal mammogram in the majority of patients (60; 88%) while 7(10.3%) had an abnormal breast magnetic resonance imaging study (MRI), and 1 had an abnormal ultrasound (US). A total of 58 patients (85%) underwent excisional biopsy, of which 3 (5.2%) showed malignancy, including 2 cases of DCIS and 1 invasive carcinoma. In addition, there was 1 case (1.7%) with pleomorphic LCIS and 11 cases with ADH (15.5%). The management of LN found on core biopsy is evolving, with some advocating surgical excision and others recommending observation. Our data show a change in diagnosis with excisional biopsy in 13 (22.4%) of patients with 2 cases of DCIS, 1 invasive carcinoma, 1 pleomorphic LCIS, and 9 cases of ADH, diagnosed on excisional biopsy. While ALH and classic LCIS are considered benign, the choice of ongoing surveillance versus excisional biopsy should be made with shared decision making with the patient, with consideration of personal and family history, as well as patient preferences.

RESUMO

OBJECTIVE: This study aimed to elucidate current medical student perceptions on barriers to a career in surgery, with a particular focus on gender-specific differences. SUMMARY BACKGROUND DATA: Although gender parity in medical school composition has been reached, women continue to be underrepresented in the field of surgery. METHODS: An anonymous, single-institution, internet-based survey conducted at Harvard Medical School. RESULTS: Approximately 720 medical students were surveyed and 261 completed the questionnaire (36.3%; 58.6% women, 41% men, 0.4% transgender). Overall, there was no significant gender difference in intention to pursue surgery (27% of men, 22% of women; P = 0.38). Sixty-nine percent of all students and 75% of those pursuing surgery reported verbal discouragement from pursuing a surgical career. Women were significantly more likely to perceive that the verbal discouragement was based on gender (P < 0.0001), age (P < 0.0001), and family aspirations (P = 0.043) compared to men. Surgical work hours and time for outside interests were the greatest deterrents for both genders. Significantly more women reported concerns about time to date or marry (P = 0.042), time to spend with family (P = 0.015), finding time during residency to have a child (P < 0.0001), taking maternity/paternity leave during residency (P < 0.0001), and being too old after residency to have a child (P < 0.0001). CONCLUSIONS: Both men and women reported high rates of verbal discouragement, but more women perceived that the discouragement was gender-based. Concerns about marriage and childbearing/rearing significantly deterred more women than men. Family aspirations were also a significant factor for men to choose an alternative career path. Additional support within the surgical field is needed to mitigate these concerns and support trainees in both their career and familial aspirations.

RESUMO

BACKGROUND: Women in surgery are often told that they are not "tough enough" to be surgeons. A Grit Score provides a validated measure of passion and perseverance, which are aspects of "toughness." METHODS: Survey data were collected from residents and attendings in all surgical fields through multiple surgical societies. Grit and burnout were measured using validated measures. RESULTS: Among surgeons, gender did not have an impact on Grit Score. Burnout had a statistically significant inverse relationship with Grit Score, and women were more likely to report burnout compared to men surgeons. CONCLUSIONS: Women in surgery have just as much grit as their male counterparts. Grit should not be a factor in women pursuing a career in surgery.

RESUMO

Atypical hyperplasia (AH) and lobular carcinoma in situ (LCIS) are markers for an increased risk of breast cancer, yet outcomes for these diagnoses are not well-documented. In this study, all breast biopsies performed for radiologic abnormalities over a 10-year period were reviewed. Patients with AH or LCIS were followed for an additional 10 years to assess subsequent rates of cancer diagnosis. Long-term follow-up showed that 25 (7.8%) patients with AH and 5 patients with LCIS (5.7%) developed breast cancer over the follow-up period, a lower rate of breast cancer development than predicted by risk models.

RESUMO

OBJECTIVE: To celebrate the increasing representation of women as leaders in American surgery and provide suggestions for increasing diversity in leadership. BACKGROUND: Women were barred from entering the practice of medicine or surgery until the mid 1800's when Elizabeth Blackwell led the way as the first woman admitted to medical school. Although the numbers of women practicing medicine and surgery have increased exponentially since Dr Blackwell graduated, the number of women in leadership positions has remained low until recently. METHODS: An analysis of the literature on the history of women in surgery and the websites of the major surgical societies. RESULTS: More women are now rising to leadership positions in surgery, both in academics and within surgical organizations. The American College of Surgeons and many other surgical societies, as well as an increasing number of academic departments of surgery have realized that women can be inspiring and capable leaders. However, increasing the number of under-represented minority women in leadership positions remains an opportunity for improvement. CONCLUSIONS: Great progress has been made in the advancement of women into leadership positions in surgery. To continue this trend and increase the number of under-represented minority women in surgery will require attention to recruitment, mentorship, and sponsorship.

RESUMO

PURPOSE: There is very little data on the effect of combining methods to better predict and improve oral antineoplastic adherence in cancer patients. The goal of this study was to evaluate the effectiveness of an intensive pharmacist intervention at the beginning of oral antineoplastic therapy versus nurse-led control group on adherence. METHODS: This was a prospective, randomized, open-label controlled trial performed in a single center hematology/oncology outpatient service to compare the effectiveness of repetitive pharmacist educational intervention on adherence rates measured at four and eight weeks after prescribing oral antineoplastic medication compared to a nurse-led control group. Both groups included investigator pill counts and self-report adherence questionnaires. RESULTS: Two-hundred patients were enrolled between 2009 and 2015. Fourteen of the 101 (14%) patients in the pharmacist group and 7 (7%) of the 99 patients in the nurse-led control group dropped out (p = 0.166). The majority of patients who remained in the study were 90-100% adherent to oral antineoplastic therapy in both groups. The pharmacist group slightly underperformed at Pill Count 2, possibly due to barriers for non-adherence. Statistically significant correlations associated with non-adherence were forgetfulness (p = 0.009), wanting to avoid side effects (p = 0.02), feeling depressed or overwhelmed (p = 0.032), or falling asleep before taking medication (p = 0.048) in both groups. CONCLUSION: The combination of pill count and patient self-report adherence is a way of improving oral antineoplastic adherence. However, significant barriers to adherence were identified such as forgetfulness, wanting to avoid side effects, feeling depressed or overwhelmed, and falling asleep before taking medications.

RESUMO

The mechanism(s) underlying obesity-related postmenopausal (PM) breast cancer (BC) are not clearly understood. We hypothesized that the increased local presence of 'obese' mammary adipocytes within the BC microenvironment promotes the acquisition of an invasive and angiogenic BC cell phenotype and accelerates tumor proliferation and progression. BC cells, treated with primary mammary adipocyte secretome from premenopausal (Pre-M) and PM obese women (ObAdCM; obese adipocyte conditioned-media) upregulated the expression of several pro-tumorigenic factors including VEGF, lipocalin-2 and IL-6. Both Pre-M and PM ObAdCM stimulated endothelial cell recruitment and proliferation and significantly stimulated BC cell proliferation, migration and invasion. IL-6 and LCN2 induced STAT3/Akt signaling in BC cells and STAT3 inhibition abrogated the ObAdCM-stimulated BC cell proliferation and migration. Expression of proangiogenic regulators including VEGF, NRP1, NRP2, IL8RB, TGFß2, and TSP-1 were found to be differentially regulated in mammary adipocytes from obese PM women. Comparative RNAseq indicated an upregulation of PI3K/Akt signaling, ECM-receptor interactions and lipid/fatty acid metabolism in PM versus Pre-M mammary adipocytes. Our results demonstrate that irrespective of menopausal status, cross-talk between obese mammary adipocytes and BC cells promotes tumor aggressiveness and suggest that targeting the LCN2/IL-6/STAT3 signaling axis may be a useful strategy in obesity-driven breast tumorigenesis.

RESUMO

Background: The arts and humanities form a critical part of medical education. In this study, we explore medical students' reflections following an arts and humanities experience. An intensive day and a half long program focused on music and reflection was designed for first-year students at Harvard Medical School. Methods: Students completed an evaluation of the experience with both open-ended and Likert scale questions. Data were analyzed using a mixed methods approach. Descriptive statistics were used to analyze quantitative data and inductive content analysis for qualitative data. Results: 168 first-year medical and dental students participated in the activity. Survey response rate was 73% (n =122). Quantitatively, the overall quality of the experience was assessed at a mean value of 4.86 points (SD = 0.37 points) out of a maximum of 5, with 5 being excellent. The qualitative evaluation illustrated how the arts and humanities experience encouraged students to reflect on their leadership and doctoring skills, taking a holistic approach to their medical education, and integrating the lessons of the arts and humanities into their medical practice. Conclusion: The arts and humanities program encouraged student reflection on profound questions in medicine related to empathy, vulnerability, and authenticity. This experience broadened students' perspectives regarding the relationship between medicine and the arts and humanities.

RESUMO

BACKGROUND: This study addresses the effectiveness of risk models and screening breast magnetic resonance imaging (MRI) in women who have atypical hyperplasia (AH), lobular carcinoma in situ (LCIS), or a family history of breast cancer, but not a genetic mutation. PATIENTS AND METHODS: A retrospective review of 444 women who had 458 breast screening MRIs at a community teaching hospital over a 12-month period between March 25, 2014 and March 31, 2015 was performed. The patients underwent high risk screening with breast MRIs alternating with mammograms every 6 months. After excluding patients with prior breast or ovarian cancer, genetic mutations, and chest wall radiation, 200 remaining patients constituted the study cohort. Over the following 5 years, the patients were screened with MRIs alternating with mammograms every 6 months. A total of 961 total MRI screenings were performed over the entire 5-year period of the study. RESULTS: A total of 200 women fit the study criteria. Of these 103 had a prior history of AH or LCIS. Over the 5-year period, 60 women dropped out of the screening regimen, 6 patients were diagnosed with breast cancer on screening MRIs, and 2 additional patients were diagnosed with breast cancer on screening mammograms. Surprisingly, the highest Tyrer-Cuzick (T-C) scores did not correlate with increased development of breast cancers in our population. CONCLUSIONS: This study shows that there is wide variation in the results of risk assessment models. Risk models may overestimate breast cancer risk, suggesting that re-evaluation of current risk assessment and screening protocols is warranted.

RESUMO

BACKGROUND: It is estimated that there are 3.8 million breast cancer survivors in the United States. Addressing survivors' post-treatment needs is critical to providing quality healthcare. METHODS: A standardized questionnaire for breast cancer survivors was employed to assess the health status, challenges, and concerns of our breast cancer patients at their survivorship visits, which were conducted 4 months after surgery. All patients were seen in the breast center at one community hospital over a 6-year period. RESULTS: Responses to a standardized questionnaire that was administered to 505 consecutive breast cancer patients at their survivorship visits 4 months after surgery were evaluated. The most striking finding was that 35% reported symptoms of insomnia, 26% had persistent fatigue, and 19% experienced fatigue that interfered with their usual activities. There was a significant association between symptoms of insomnia and radiation treatment (P = .004), pain (P < .001), hormone therapy (P < .01), and side effects of hormone therapy (P < .0001). There was also a significant association between fatigue and pain (P < .001) as well as side effects from hormone treatment (P = .0036). CONCLUSIONS: Over a third (35%) of breast cancer patients suffer from insomnia, while over a quarter (26%) complain of fatigue at their survivorship assessments. Contributing factors include radiation treatment, pain, and hormonal therapy. Careful assessment and treatment of fatigue and symptoms of insomnia in breast cancer patients is needed to improve quality of life for survivors.

RESUMO

BACKGROUND: Mentorship is an important factor for career promotion and professional development. The Women in Surgery Committee developed a mentorship program that matched early career female surgeons to senior female surgeons for 1 year. We hypothesized participation in the program would empower junior surgeons by providing opportunities to network and hone skills necessary to attain their career goals. METHODS: Survey was sent 4 to 6 weeks after program completion. Statements about mentorship and value of the Women in Surgery Committee program were ranked on a 5-point Likert scale ranging from strongly disagree (1) to strongly agree (5). Participants were compared based on frequency of encounters using Student's t-test. RESULTS: A total of 105 pairs were identified; response rate was 60%. Results reported as (mean ± SD). Participants believed mentorship was essential for young surgeons (4.5 ± 1.0), and limiting the program to female surgeons added value (4.4 ± 0.6). When compared with mentees who met less than 4 times in a year, those who met 4 or more times perceived the program as beneficial (4.4 ± 0.82, p < 0.001). Mentees who met 4 or more times in a year benefitted from creating and achieving goals (4.3 ± 0.75, p < 0.001), setting expectations (4.5 ± 0.6, p < 0.001), providing networking opportunities (4.1 ± 1.1, p < 0.05), and developing professional skills (3.9 ± 0.98). CONCLUSION: The Women in Surgery Committee Mentorship Program provides an opportunity for young female surgeons; however, perceived benefit is dependent on mentee engagement.

RESUMO

OBJECTIVES: A comprehensive decision aid (DA) for women ≥70 years with Stage I ER+/HER2-negative breast cancer was developed to support locoregional and systemic treatment decision-making. We aimed to test the acceptability of this novel DA in women newly-diagnosed with breast cancer. MATERIALS AND METHODS: Women ≥70 diagnosed with Stage I, ER+/HER2- breast cancer were recruited from three Boston-area hospitals. They underwent baseline interviews after initial surgical consultation, reviewed the DA, and were surveyed <2 weeks later to determine DA acceptability (e.g., was it helpful?), changes in decisional conflict, stage of decision-making, and knowledge. Participants could optionally complete a three-month follow-up. Paired t-tests and McNemar's tests were used for statistical comparisons, and thematic analyses were conducted to identify themes in participants' open-ended comments. RESULTS: Thirty-three of 56 eligible patients approached completed the baseline and acceptability surveys, and 25 completed the three-month follow-up. Participants' mean age was 74.7 years (±3.8). Nearly all participants (n = 31, 94%) strongly agreed that the DA was helpful and felt that the DA prepared them for treatment decision-making, with a mean decision preparation score of 4.1 (out of 5.0); 6% (n = 2) found it very anxiety provoking. Knowledge improved with a mean of 9.0 out of 14 questions correct at baseline to 10.6 correct on the acceptability survey (p < 0.0001). CONCLUSIONS: A DA tailored to women ≥70 with Stage I, ER+, HER2- breast cancer increased knowledge and was perceived to be helpful by older women. A randomized controlled trial is needed to evaluate its efficacy.

RESUMO

Scholarly communication in science, technology, and medicine has been organized around journal-based scientific publishing for the past 350 years. Scientific publishing has unique business models and includes stakeholders with conflicting interests-publishers, funders, libraries, and scholars who create, curate, and consume the literature. Massive growth and change in scholarly communication, coinciding with digitalization, have amplified stresses inherent in traditional scientific publishing, as evidenced by overwhelmed editors and reviewers, increased retraction rates, emergence of pseudo-journals, strained library budgets, and debates about the metrics of academic recognition for scholarly achievements. Simultaneously, several open access models are gaining traction and online technologies offer opportunities to augment traditional tasks of scientific publishing, develop integrated discovery services, and establish global and equitable scholarly communication through crowdsourcing, software development, big data management, and machine learning. These rapidly evolving developments raise financial, legal, and ethical dilemmas that require solutions, while successful strategies are difficult to predict. Key challenges and trends are reviewed from the authors' perspective about how to engage the scholarly community in this multifaceted process.

RESUMO

The purpose of this study is to describe our experience with nipple-sparing mastectomy and immediate reconstruction, with particular attention to patient satisfaction, aesthetic results, and nipple sensation. Immediate reconstruction was performed on 17 breasts in 10 patients, using either implants or autologous tissue flaps. Assessment of outcomes was performed through patient interviews, a self-reported patient satisfaction survey and review of postoperative photographs. Short-term complications included partial loss of the nipple-areolar complex requiring debridement (n = 3) and removal of the nipple-areolar complex (n = 2) for occult ductal carcinoma in situ. While all patients with completed breast reconstructions were satisfied with their general reconstructive experience, 6 of 9 patients were aesthetically satisfied with their breast reconstruction. Postoperative nipple sensation was reported in 75% of patients, although sensation was low (mean of 2.8 of 10). As nipple-sparing mastectomy is becoming an increasing patient preference, preoperative discussion needs to address expectations, aesthetic satisfaction, and long-term cancer control.

RESUMO

OBJECTIVES: Since women ≥70 years with early stage, estrogen receptor positive (ER+), HER2 negative breast cancer face several preference-sensitive treatment decisions, the investigative team aimed to develop a pamphlet decision aid (DA) for such women. MATERIALS AND METHODS: The content of the DA was informed by literature review, international criteria, and expert feedback, and includes information on benefits and risks of lumpectomy versus mastectomy, lymph node surgery, radiotherapy after lumpectomy, and endocrine therapy. It considers women's overall health and was written using low literacy principles. Women from two Boston-based hospitals who were diagnosed in the past 6-24 months were recruited to provide feedback on the DA and its acceptability. The DA was iteratively revised based on their qualitative input. RESULTS: Of 48 eligible women contacted, 35 (73%) agreed to participate. Their mean age was 74.3 years; 33 (94%) were non-Hispanic white; and 24 (67%) were college graduates. Overall, 26 (74%) thought the length of the DA was just right, 29 (83%) thought all or most of the information was clear, 32 (91%) found the DA helpful, and 33 (94%) would recommend it. In open ended comments, participants noted that the DA was clear, well-organized, and would help women prepare for and participate in treatment decision-making. CONCLUSIONS: The investigative team developed a novel breast cancer treatment DA that is acceptable to women ≥70 years with a history of ER+, HER2-, early stage breast cancer. Next, the DA's efficacy needs to be tested with diverse older women newly diagnosed with breast cancer.

RESUMO

Matrix metalloproteinases (MMP) and a disintegrin and metalloprotease 12 (ADAM 12) can be detected in the urine of breast cancer patients and provide independent prediction of disease status. To evaluate the potential of urinary metalloproteinases as biomarkers to predict breast cancer risk status, urine samples from women with known risk marker lesions, atypical hyperplasia and lobular carcinoma in situ (LCIS), were analyzed. Urine samples were obtained from 148 women: 44 women with atypical hyperplasia, 24 women with LCIS, and 80 healthy controls. MMP analysis was done using gelatin zymography and ADAM 12 analysis was done via immunoblotting with monospecific antibodies and subsequent densitometric measurement. Positive urinary MMP-9 levels indicated a 5-fold risk of atypical hyperplasia and >13-fold risk of LCIS compared with normal controls. Urinary ADAM 12 levels were significantly elevated in women with atypical hyperplasia and LCIS from normal controls, with receiver operating characteristic curve analysis showing an area under the curve of 0.914 and 0.950, respectively. To assess clinical applicability, a predictive index was developed using ADAM 12 in conjunction with Gail risk scores for women with atypia. Scores above 2.8 on this ADAM 12-Gail risk prediction index score are predictive of atypical hyperplasia (sensitivity, 0.976; specificity, 0.977). Our data suggest that the noninvasive detection and analysis of urinary ADAM 12 and MMP-9 provide important clinical information for use as biomarkers in the identification of women at increased risk of developing breast cancer.

RESUMO

To inform medical education reform efforts, we systematically collected information on the level of arts and humanities engagement in our medical school community. Attitudes regarding incorporating arts and humanities-based teaching methods into medical education and patient care were also assessed. An IRB-approved survey was electronically distributed to all faculty, residents, fellows, and students at our medical school. Questions focused on personal practice of the arts and/or humanities, as well as perceptions of, and experience with formally incorporating these into medical teaching. Of 13,512 community members surveyed, 2,775 responded (21% overall response rate). A majority of respondents agreed or strongly agreed that medical education and patient care could be "enhanced" by the integration of the arts (67% and 74% respectively). There was enthusiastic support for the creation of a formal program in the arts at our medical school (72 %). Integration of the arts into medical education may have a role in improving the quality of medical training and would likely be well received by teachers and learners.
