RESUMO

PURPOSE: Ability to return to work (RTW) is an important aspect of breast cancer that is limited for many survivors. With 90% survivorship in the USA, it is imperative that focus shifts toward the improvement of physical arm function to improve survivors' ability to RTW. This narrative review discusses the role of physical arm function and demographic disparities in breast cancer survivor RTW. METHODS: Literature on physical function, arm function, and demographic disparities following breast cancer treatment and their implications for RTW is discussed. RESULTS: The ability to RTW is a key component of recovery for breast cancer survivors, but challenges and inequalities persist. Treatment effects can induce and prolong functional disability, affecting survivors' ability to RTW. These effects may be compounded for survivors whose occupation requires physical arm function. The RTW landscape, including the occupations survivors have, the physical function required for job tasks, and availability of workplace accommodations, is also unclear. Additional demographic disparities (e.g., income, live in rural area) exist, but the extent to which these factors influence RTW is not well understood. More work is needed to understand the compounded impact of treatment effects, demographic disparities, and occupational factors on RTW. Multidisciplinary rehabilitation that includes occupational counseling and exercise is a promising approach, but widespread adoption in the US healthcare model presents an ongoing challenge. Areas for further research are highlighted. CONCLUSION: There is an incomplete understanding of the effects of treatment on physical arm function and the role of demographic disparities on breast cancer survivor RTW.

RESUMO

BACKGROUND: Although metastatic breast cancer (MBC) survival is improving, symptoms remain a significant burden. Returning to a cancer center for symptom management can be challenging. Technology-enabled supportive care platforms are worth exploration. METHODS: Seventeen patients with MBC were randomized to immediate or delayed start for a 3-month intervention that included daily tablet-based guideline-concordant self-care for pain, distress, fatigue, and sleep disturbance, as well as weekly calls with a patient navigator. The primary outcome was patient acceptability. We also assessed feasibility, patient satisfaction, and cost and compared between group differences for symptoms. RM-ANOVA examined between group differences over time. Hedges' d effect sizes quantified magnitude of differences in change between immediate and delayed start. RESULTS: Sixty-eight percent of patients approached accepted the tablet-based intervention. Patients interacted with the tablet 48% of possible days. Patient satisfaction ranged from 83 for walking to 49% for the psychological interventions. The cost of delivering Nurse AMIE for 3 months was $570.23. Small nonsignificant improvements were found for fatigue (d=0.24). Nonsignificant, but potentially clinically meaningful, moderate reductions were found for sleep (d=0.65) and distress (d=0.74). DISCUSSION: A tablet-based supportive care platform that offers guideline-concordant self-care for pain, fatigue, sleep, and distress was observed to be highly acceptable and feasible for patients with metastatic breast cancer. Patient satisfaction scores and initial evaluation of efficacy are promising, and the platform warrants further investigation. IMPLICATIONS FOR CANCER SURVIVORS: Technology-based self-care is a promising option to address symptoms in patients with metastatic breast cancer.

RESUMO

The emergence of the severe acute respiratory syndrome coronavirus 2 pandemic has created an unprecedented healthcare, social, and economic disaster. Wearing of masks and social distancing can significantly decrease transmission and spread, however, due to circumstances such as medical or dental intervention and personal choice these practices have not been universally adopted. Additional strategies are required to lessen transmission. Nasal rinses and mouthwashes, which directly impact the major sites of reception and transmission of human coronaviruses (HCoV), may provide an additional level of protection against the virus. Common over-the-counter nasal rinses and mouthwashes/gargles were tested for their ability to inactivate high concentrations of HCoV using contact times of 30 s, 1 min, and 2 min. Reductions in titers were measured by using the tissue culture infectious dose 50 (TCID50 ) assay. A 1% baby shampoo nasal rinse solution inactivated HCoV greater than 99.9% with a 2-min contact time. Several over-the-counter mouthwash/gargle products including Listerine and Listerine-like products were highly effective at inactivating infectious virus with greater than 99.9% even with a 30-s contact time. In the current manuscript we have demonstrated that several commonly available healthcare products have significant virucidal properties with respect to HCoV.

RESUMO

PURPOSE: Breast cancer survivorship is common (90% of women survive 5 or more years), but many women are not able to return to full function and well-being after treatment due to functional limitations, persistent pain, and inability to perform daily activities. Since each surgical reconstructive option (e.g., autologous tissue flaps versus implants) can impact shoulder and arm function differently, it is important to understand how shoulder and upper limb strength, mobility, and function are influenced by the type of surgical intervention. Efforts can then focus on prehabiliation strategies to prevent the onset of limitations and on developing rehabilitation protocols that directly target shortcomings. METHODS: The current paper presents a review summarizing how shoulder and upper limb function may be affected by surgical mastectomy and breast reconstruction. RESULTS: Mastectomy and breast reconstruction with implants or autologous tissues present different functional outcomes for patients. Each surgical procedure is associated with unique sequelae derived from the tissues and procedures associated with each surgery. Characterizing the specific functional outcomes associated with each surgical approach will promote the development of targeted rehabilitation strategies that can be implemented into a multidisciplinary treatment planning pathway for breast cancer patients. CONCLUSIONS: Surgical treatments for breast cancer, including mastectomy and breast reconstruction, can have negative effects. Focused efforts are needed to better understand treatment-specific effects so that targeted rehabilitation can be developed to improve patient function, QoL, and ability to return to work and life activities post-breast cancer.

RESUMO

INTRODUCTION: Angiosarcoma is a rare soft tissue malignancy of endothelial cells, generally associated with a poor prognosis. Due to its rarity, randomized trials are difficult to conduct and a consensus on the treatment of angiosarcoma has not been reached. The role, efficacy, and timing of chemotherapy in AS treatment remain uncertain, and as stated, no large-scale trials have been able to establish definitive recommendations. CASE DESCRIPTIONS: Here we describe the successful use of chemotherapy followed by radiation for a case of lower extremity angiosarcoma, and a case of breast angiosarcoma treated with neoadjuvant chemotherapy followed by surgical resection. Systemic therapy consisted of weekly doxorubicin, paclitaxel, and cisplatin. This regimen resulted in a full clinical remission in the first patient and a pathologic complete response in the second. DISCUSSION: These cases suggest that the use of the doxorubicin, cisplatin and paclitaxel combination could be an effective alternative to radical surgical excision in extremity sarcomas, and an effective adjuvant treatment to mastectomy in cutaneous radiation-associated angiosarcoma of the breast due to their independent efficacy against angiosarcoma. A randomized trial utilizing neoadjuvant combined doxorubicin, paclitaxel and cisplatin followed by either surgery or radiation, with endpoints assessing pathologic and overall response as well as progression free survival is warranted based on these cases. CONCLUSION: The role of neoadjuvant chemotherapy in the treatment of angiosarcoma should be reconsidered considering its ability to provide important prognostic information and improve the likelihood of curative surgery.

RESUMO

BACKGROUND: Breast surgeons negotiating employment agreements have little national data available. To reduce this knowledge gap, the Education Committee of the American Society of Breast Surgeons conducted a survey of its membership. METHODS: In 2014, survey questionnaires were sent to society members. Data collected included gender, type of practice, percentage devoted to breast surgery, volume of breast cases, work relative value units, location, benefits, and salary. Descriptive statistics were provided, and a multinomial logistic regression was performed to analyze the impact of various potential factors on salary. RESULTS: Of the 2784 members, a total of 843 observations were included. Overall, 54% of respondents dedicated 100 % of their practice to breast surgery, 64.3% were female, and 40% were fellowship-trained in breast surgery or surgical oncology. The mean income in 2013 was $330.7k. Results from a multinomial model showed gender (p < 0.0001), ownership (p = 0.03), years of practice (p < 0.0001), practice setting (p < 0.0001), practice volume (p < 0.0001), and geographic location (p = 0.05) were statistically significant. After adjusting for other variables, the expected income was higher for males ($378k vs. $310k). The lowest expected income by practice setting was in solo private practice ($249.2k), followed by single-specialty private practice ($285.8k), and academic ($308.5k), with the highest being multispecialty group private practice ($346.6k) and hospital-employed practice ($368.0k). Practice 100% dedicated to breast surgery had a lower than expected income ($326k vs. $343k). CONCLUSIONS: Salary-specific data for breast surgeons are limited, and differences in salary were seen across geographic regions, type of practice, and gender. This type of breast-surgeon-specific data may be helpful in ensuring equitable compensation.

RESUMO

PURPOSE: The American Society of Breast Surgeons (ASBrS) sought to provide an evidence-based guideline on the use of neoadjuvant systemic therapy (NST) in the management of clinical stage II and III invasive breast cancer. METHODS: A comprehensive nonsystematic review was performed of selected peer-reviewed literature published since 2000. The Education Committee of the ASBrS convened to develop guideline recommendations. RESULTS: A performance and practice guideline was prepared to outline the baseline assessment and perioperative management of patients with clinical stage II-III breast cancer under consideration for NST. RECOMMENDATIONS: Preoperative or NST is emerging as an important initial strategy for the management of invasive breast cancer. From the surgeon's perspective, the primary goal of NST is to increase the resectability of locally advanced breast cancer, increase the feasibility of breast-conserving surgery and sentinel node biopsy, and decrease surgical morbidity. To ensure optimal patient selection and efficient patient care, the guideline recommends: (1) baseline breast and axillary imaging; (2) minimally invasive biopsies of breast and axillary lesions; (3) determination of tumor biomarkers; (4) systemic staging; (5) care coordination, including referrals to medical oncology, radiation oncology, plastic surgery, social work, and genetic counseling, if indicated; (6) initiation of NST; (7) post-NST breast and axillary imaging; and (8) decision for surgery based on extent of disease at presentation, patient choice, clinical response to NST, and genetic testing results, if performed.

RESUMO

Prior research has used focus group methodology to investigate cultural factors impacting the breast cancer experience of women of various ethnicities including African-Americans; however, this work has not specifically addressed treatment decision-making. This study identifies key issues faced by African-American women diagnosed with breast cancer regarding treatment decisions. We used an interpretive-descriptive study design based on qualitative data from three focus groups (n = 14) representing a population of African-American women in central Pennsylvania. Participants were asked to think back to when they were diagnosed with breast cancer and their visit with the breast surgeon. Questions were asked about the actual visit, treatment choices offered, sources of information, and whether the women felt prepared for the surgery and subsequent treatments. The prompts triggered memories and encouraged open discussion. The most important themes identified were fear across the breast cancer disease trajectory, a preference for visual information for understanding the diagnosis and surgical treatment, and support systems relying on family and friends, rather than the formal health-care system. Our results have implications for practice strategies and development of educational interventions that will help breast cancer patients better understand their diagnosis and treatment options, encourage their participation in treatment decision-making, and provide psychosocial support for those at high risk for emotional distress.

RESUMO

BACKGROUND: This pilot study assessed the levels of patient emotional distress and impact on clinic throughput time. METHODS: From April through August 2012, 149 breast cancer patients at the Penn State Hershey Breast Center were screened with the emotions thermometer (ET), a patient-rated visual 0-10 scale that measures distress, anxiety, depression, anger, burden, and need for help. Also, patients indicated their most pressing cancer-related concerns. Clinic visit time was computed and compared with a control group. RESULTS: Using a previously validated cut point ≥4 for any thermometer, we found emotional difficulty in the following proportions: distress 22 %, anxiety 28 %, depression 18 %, anger 14 %, burden 16 %, and need for help 10 %; 35 % scored above the cut point on at least 1 thermometer. We found higher levels of distress in all domains associated with younger age at diagnosis. More extensive surgery (bilateral mastectomy vs unilateral mastectomy vs. lumpectomy) was correlated with higher levels of psychosocial distress. Most often cited concerns, experienced by >20 %, included eating/weight, worry about cancer, sleep problems, fatigue, anxiety, and pain. Mean clinic visit time for evaluable patients screened using the ET (n = 109) was 43.9 min (SD 18.6), compared with 42.6 min (SD 16.2) for the control group (n = 50). CONCLUSIONS: Utilizing the ET, more than one-third of women screened met criteria for psychological distress. Younger age at diagnosis and more extensive surgery were risk factors. The ET is a simple validated screening tool that identifies patients in need of further psychological evaluation without impacting clinic throughput time.

RESUMO

BACKGROUND: The purpose of this study was to assess national practices of surgeons who treat breast cancer in order to identify opportunities to improve patient education. METHODS: In June 2012, the membership of the American Society of Breast Surgeons (ASBrS) (n = 2,818) was surveyed via email questionnaire to evaluate their current practice of shared decision making and informed consent for breast cancer patients. RESULTS: A total of 737 members (26 %) responded, including 384 breast surgeons and 306 general surgeons, 13 midlevel providers, and 25 other specialists. It was found that 90 % of surgeons spent more than 30 min meeting with a new cancer patient, and of these, 30 % spent more than an hour. Surgeons who spent more than 1 h face-to-face with a new cancer patient reported higher levels of overall patient knowledge compared with those who spent less (mean = 3.80 vs. 3.64 of 5; p = 0.001). Also, 89 % of respondents reported using educational tools, of whom more than 90 % used written tools. In addition, 65 % of members stated an interest in a free online educational tool if available and indicated a preference for a flexible tool that could be used by the patient alone or with a nurse. CONCLUSIONS: While practice patterns may vary, our results reveal that one-third of surgeons spend at least 1 h in consultation with a new breast cancer patient. More time spent translated to a higher perceived patient understanding of their disease and treatment options. Although the majority of surgeons currently use written materials, there was clear support for a free online educational tool.

RESUMO

OBJECTIVE: Simulators have replaced some standardized patients in medical student teaching, and their use seems to decrease anxiety related to the clinical breast examination (CBE). We compared learning the CBE on a breast palpation simulator with learning on a standardized patient with respect to skill acquisition and comfort level. METHODS: At Penn State College of Medicine, the class of 2008 (historical control group, n = 113) learned the CBE on a standardized patient, whereas the class of 2009 (experimental group, n = 131) learned on the breast palpation simulator. We used measures of the process (conducting the CBE) and measures of the outcome (examination scores and detection of abnormal findings). During their third-year surgical clerkship, students in both groups completed a questionnaire reporting the number of CBEs performed and confidence in performing the CBE. The students then performed an observed examination on the simulator, and the number of positive findings detected was recorded. The mean number of positive findings was compared between groups, and an economic analysis was conducted. RESULTS: The experimental group had a significantly higher mean examination score than the historical control. In subgroups, this difference was significant for those who reported performing 0-5 clinical examinations but for not those who had performed >6 examinations. On individual items, the experimental group scored significantly higher in examining for neck nodes, nipple retraction, skin changes, and axillary evaluation. The 2 groups did not differ significantly in the mean number of positive findings detected or in ratings of comfort level. CONCLUSIONS: Medical students who learned the CBE on breast palpation simulators performed as well or better than those who learned on standardized patients; however, a subgroup analysis revealed that the benefit was limited to students with less clinical experience.

RESUMO

BACKGROUND: The purpose of this study was to determine the rate of nausea and vomiting in women following breast surgery (PONV) under general anesthesia (GA), before and after the introduction of a standardized prophylactic anti-emetic (AE) regimen. METHODS: We performed a retrospective review of eligible patients, between July 2001 and March 2003. Patients operated on before September 2002 had standard preoperative care (old cohort [OC]); patients operated on after September 2002 were treated prophylactically with oral dronabinol 5 mg and rectal prochlorperazine 25 mg (new cohort [NC]). Data were collected from hospital records regarding age, diagnosis, comorbid conditions, previous anesthesia history, anesthesia and operative details, episodes PONV, and use of AE. The rate and severity of PONV was calculated for both cohorts. RESULTS: Two hundred forty-two patients were studied: 127 patients in the OC and 115 patients in the NC. The median age was 56 years (range 32 to 65). The rate of nausea and vomiting were significantly better in the patients treated prophylactically with dronabinol and prochlorperazine (59% vs. 15%, P < .0001 and 29% vs. 3%, P < .0001). Twenty patients in the OC were given some prophylactic AE treatment and 12 (60%) of them required further treatment; only 12 of 109 patients (11%) in the NC required further AE treatment (P < .0001). CONCLUSION: PONV is a significant problem in breast surgical patients. Preoperative treatment with dronabinol and prochlorperazine significantly reduced the number and severity of episodes of PONV.

RESUMO

BACKGROUND: The number of women reaching top ranks in academic surgery is remarkably low. The purpose of this study was to identify: 1) barriers to becoming a female surgical leader; 2) key attributes that enable advancement and success; and 3) current leadership challenges faced as senior leaders. METHODS: Semi-structured interviews of ten female surgical leaders queried the following dimensions: attributes for success, lessons learned, mistakes, key career steps, the role of mentoring, gender advantages/disadvantages, and challenges. RESULTS: Perseverance (60%) and drive (50%) were identified as critical success factors, as were good communication skills, a passion for scholarship, a stable home life and a positive outlook. Eighty percent identified discrimination or gender prejudice as a major obstacle in their careers. While 90% percent had mentors, 50% acknowledged that they had not been effectively mentored. Career advice included: develop broad career goals (50%); select a conducive environment (30%); find a mentor (60%); take personal responsibility (40%); organize time and achieve balance (40%); network (30%); create a niche (30%); pursue research (30%); publish (50%); speak in public (30%); and enjoy the process (30%). Being in a minority, being highly visible and being collaborative were identified as advantages. Obtaining buy-in and achieving consensus was the greatest leadership challenge reported. CONCLUSIONS: Female academic surgeons face challenges to career advancement. While these barriers are real, they can be overcome by resolve, commitment, and developing strong communication skills. These elements should be taken into consideration in designing career development programs for junior female surgical faculty.

RESUMO

OBJECTIVE: To determine the identification of sentinel lymph node biopsy (SLNB) in breast cancer patients after intraoperative injection of unfiltered technetium-99m sulfur colloid (Tc-99) and blue dye. BACKGROUND: SLNB guided by a combination of radioisotope and blue dye injection yields the best identification rates in breast cancer patients. Radioisotope is given preoperatively, without local anesthesia, whereas blue dye is given intraoperatively. We hypothesized that, because of the rapid drainage noted with the subareolar injection technique of radioisotope, intraoperative injection would be feasible and less painful for SLN localization in breast cancer patients. METHODS: Intraoperative injection of Tc-99 and confirmation blue dye was performed using the subareolar technique for SLNB in patients with operable breast cancer. The time lapse between injection and axillary incision, the background count, the preincision and ex vivo counts of the hot nodes, and the axillary bed counts were documented. The identification rate was recorded. RESULTS: Ninety-six SLNB procedures were done in 88 patients with breast cancer employing intraoperative subareolar injection technique for both radioisotope (all 96 procedures) and blue dye (93 procedures) injections. Ninety-three (97%) procedures had successful identification; all SLNs were hot; 91 (of 93 procedures with blue dye) were blue and hot. The mean time from radioisotope injection to incision was 19.9 minutes (SD 8.5 minutes). The mean highest 10 second count was 88,544 (SD 55,954). Three of 96 (3%) patients with failure of localization had previous excisional biopsies: 1 circumareolar and 2 upper outer quadrant incisions that may have disrupted the lymphatic flow. CONCLUSION: Intraoperative subareolar injection of radioisotope rapidly drains to the SLNs and allows immediate staging of the axilla, avoiding the need to coordinate diagnostic services and a painful preoperative procedure.

RESUMO

BACKGROUND: Sentinel lymph node biopsy (SLNB) is deemed suitable only for unifocal breast cancers since multiple foci of cancers may drain to different nodes. We hypothesized that subareolar injection (SI) could identify the sentinel lymph nodes (SLN) accurately in patients with multiple cancers (MC) in the breast. METHODS: We prospectively employed SI of lymphazurin or technetium sulfur colloid, or both, for the identification of SLN in patients with MC in the breast. All patients underwent axillary dissection to compute the accuracy of SLNB. RESULTS: Forty patients presented with MC in the same breast between January 1996 and July 2002. Fifty-two percent (21 of 40) of patients had involvement of more than 1 quadrant; 18% (7 of 40) had more than 1 histologic type of cancers. SLNs were successfully identified in 100% of patients. Axillary disease was present in 63% (25 of 40) of patients. Sensitivity of SLNB was 100% and false negative rate was 0%. The SLN was the only node involved in 45% (18 of 40) of patients. CONCLUSIONS: SLNB using the SI technique may be an alternative to complete axillary dissection in patients with multiple breast cancers.
