Does following a breast cancer patient for a day enhance medical student empathy?

OBJECTIVES: The aim of this study was to investigate the hypothesis that following a breast cancer patient for a day would enhance empathy in medical students. MATERIALS AND METHODS: This was a theory-testing case study of 4th year medical students completing a one week clinical attachment in breast disease in a UK University teaching hospital, in which half were assigned to an intervention of 'Follow a Patient' for a day, and the other half were controls. Reflective writing produced by the students at the end of the week was analysed using grounded theory and thematic analysis. The results were then unblinded to explore possible differences between the two groups of students. RESULTS: Thematic analysis of 52 student reflections identified 14 open codes which grouped into five global themes, one of which was 'Demonstrates Empathy'. A total of 20 students demonstrated empathy in their writing, 15/27 from the study group and 5/25 from the control group, a difference that was significantly different p < .01. CONCLUSIONS: This 'Follow a Patient' strategy is a useful model to include within an undergraduate curriculum to enhance medical student empathy.

Uptake and efficacy of bilateral risk reducing surgery in unaffected female BRCA1 and BRCA2 carriers.

BACKGROUND: Women testing positive for BRCA1/2 pathogenic variants have high lifetime risks of breast cancer (BC) and ovarian cancer. The effectiveness of risk reducing surgery (RRS) has been demonstrated in numerous previous studies. We evaluated long-term uptake, timing and effectiveness of risk reducing mastectomy (RRM) and bilateral salpingo-oophorectomy (RRSO) in healthy BRCA1/2 carriers. METHODS: Women were prospectively followed up from positive genetic test (GT) result to censor date. χ² testing compared categorical variables; Cox regression model estimated HRs and 95% CI for BC/ovarian cancer cases associated with RRS, and impact on all-cause mortality; Kaplan-Meier curves estimated cumulative RRS uptake. The annual cancer incidence was estimated by women-years at risk. RESULTS: In total, 887 women were included in this analysis. Mean follow-up was 6.26 years (range=0.01-24.3; total=4685.4 women-years). RRS was performed in 512 women, 73 before GT. Overall RRM uptake was 57.9% and RRSO uptake was 78.6%. The median time from GT to RRM was 18.4 months, and from GT to RRSO-10.0 months. Annual BC incidence in the study population was 1.28%. Relative BC risk reduction (RRM versus non-RRM) was 94%. Risk reduction of ovarian cancer (RRSO versus non-RRSO) was 100%. CONCLUSION: Over a 24-year period, we observed an increasing number of women opting for RRS. We showed that the timing of RRS remains suboptimal, especially in women undergoing RRSO. Both RRM and RRSO showed a significant effect on relevant cancer risk reduction. However, there was no statistically significant RRSO protective effect on BC.

Breast cancer incidence and early diagnosis in a family history risk and prevention clinic: 33-year experience in 14,311 women.

PURPOSE: Women at increased familial breast cancer risk have been offered screening starting at an earlier age and increased frequency than national Screening Programmes for over 30 years. There are limited data on longer-term largescale implementation of this approach on cancer diagnosis. METHODS: Women at our institution at ≥ 17% lifetime breast cancer risk have been offered enhanced screening with annual mammography starting at age 35 or 5-years younger than youngest affected relative, with upper age limit 50 for moderate and 60 for high-risk. Breast cancer pathology, stage and receptor status were assessed as well as survival from cancer diagnosis by Kaplan-Meier analysis. RESULTS: Overall 14,311 women were seen and assessed for breast cancer risk, with 649 breast cancers occurring in 129,119 years follow up (post-prevalent annual incidence = 4.55/1000). Of 323/394 invasive breast cancers occurring whilst on enhanced screening, most were lymph-node negative (72.9%), T1 (≤ 20 mm, 73.2%) and stage-1 (61.4%), 126/394 stage2-4 (32%). 10-year breast cancer specific survival was 91.3% (95% CI 87.4-94.0) better than the 75.9% (95% CI 74.9-77.0) published for England in 2013-2017. As expected, survival was significantly better for women with screen detected cancers (p < 0.001). Ten-year survival was particularly good for those diagnosed ≤ 40 at 93.8% (n = 75; 95% CI 84.2-97.6). Women with lobular breast cancers had worse 10-year survival at 85.9% (95% CI 66.7-94.5). Breast cancer specific survival was good for 119 BRCA1/2 carriers with 20-year survival in BRCA1:91.2% (95% CI 77.8-96.6) and 83.8% (62.6-93.5) for BRCA2. CONCLUSIONS: Targeted breast screening in women aged 30-60 years at increased familial risk is associated with good long-term survival that is substantially better than expected from population data.

Immediate breast reconstruction does not increase postmastectomy pain.

BACKGROUND: Postmastectomy pain syndrome (PMPS) is a recognized complication of breast surgery, with a reported prevalence of 20­52 %. We investigated whether patients having immediate reconstruction (IR) reported more long-term pain compared to those having mastectomy alone (MA). We also investigated treatment factors influencing PMPS. METHODS: In a single center, all patients who underwent MA or IR between January 2009 and June 2011 and attended for follow-up between February 2012 and July 2012 were identified. Patients were invited to complete two questionnaires, a pain intensity visual analog scale (VAS, scored 0 to 10) and the PainDetect screening tool for neuropathic pain. RESULTS: Of 318 patients due to attend, 272 (86 %) submitted complete questionnaires. Of these, 134 (49 %) women had IR (implant based n = 93, pedicled flaps n = 33, free flaps n = 8). The overall point prevalence pain was low, with 221 (81 %) reporting VAS current pain as zero. Only 8 (3 %) patients reported a VAS score above 4. Six (2 %) patients had a positive PainDetect score. The percentage of patients reporting VAS scores greater than zero and positive or borderline PainDetect scores was similar for MA and IR (VAS: 13 and 14 %, respectively; PainDetect: 6 and 11 %, respectively). Radiotherapy was the strongest predictor of neuropathic pain. CONCLUSIONS: In this cohort, the prevalence of PMPS was lower than historic reports. We find no evidence of increased overall pain intensity or chronic neuropathic pain after IR compared to MA despite additional tissue dissection and potential donor site morbidity. This adds support to the positive benefits of breast reconstruction.

Uptake of bilateral-risk-reducing-mastectomy: Prospective analysis of 7195 women at high-risk of breast cancer.

BACKGROUND: Bilateral-Risk-Reducing-Mastectomy-(BRRM) is well described in BRCA1/2 pathogenic variant carriers. However, little is known about the relative uptake, time trends or factors influencing uptake in those at increased breast cancer risk not known to be carriers. The aim of this study is to assess these factors in both groups. METHODS: BRRM uptake was assessed from entry to the Manchester Family History Clinic or from date of personal BRCA1/2 test. Follow up was censored at BRRM, breast cancer diagnosis, death or January 01, 2020. Cumulative incidence and cause specific and competing risk regression analyses were used to assess the significance of factors associated with BRRM. RESULTS: Of 7195 women at ≥25% lifetime breast cancer risk followed for up to 32 years, 451 (6.2%) underwent pre-symptomatic BRRM. Of those eligible in different risk groups the 20-year uptake of BRRM was 47.7%-(95%CI = 42.4-53.2%) in 479 BRCA1/2 carriers; 9.0% (95%CI = 7.26-11.24%) in 1261 women at ≥40% lifetime risk (non-BRCA), 4.8%-(95%CI = 3.98-5.73%) in 3561 women at 30-39% risk and 2.9%-(95%CI = 2.09-4.09%) in 1783 women at 25-29% lifetime risk. In cause-specific Cox regression analysis death of a sister with breast cancer<50 (OR = 2.4; 95%CI = 1.7-3.4), mother<60 (OR = 1.9; 95%CI = 1.5-2.3), having children (OR = 1.4; 95%CI = 1.1-1.8), breast biopsy (OR = 1.4; 95%CI = 1.0-1.8) were all independently associated with BRRM uptake, while being older at assessment was less likely to be associated with BRRM (>50; OR = 0.26,95%CI = 0.17-0.41). Uptake continued to rise to 20 years from initial risk assessment. CONCLUSION: We have identified several additional factors that correlate with BRRM uptake and demonstrate continued increases over time. These factors will help to tailor counselling and support for women.

The Angelina Jolie effect: Contralateral risk-reducing mastectomy trends in patients at increased risk of breast cancer.

Contralateral risk-reducing mastectomy (CRRM) rates have tripled over the last 2 decades. Reasons for this are multi-factorial, with those harbouring a pathogenic variant in the BRCA1/2 gene having the greatest survival benefit. On May 14th, 2013, Angelina Jolie shared the news of her bilateral risk-reducing mastectomy (BRRM), on the basis of her BRCA1 pathogenic variant status. We evaluated the impact of this news on rates of CRRM in women with increased risk for developing breast cancer after being diagnosed with unilateral breast cancer. The prospective cohort study included all women with at least a moderate lifetime risk of developing breast cancer who attended our family history clinic (1987-2019) and were subsequently diagnosed with unilateral breast cancer. Rates of CRRM were then compared between patients diagnosed with breast cancer before and after Angelina Jolie's announcement (pre- vs. post-AJ). Of 386 breast cancer patients, with a mean age at diagnosis of 48 ± 8 years, 268 (69.4%) were diagnosed in the pre-AJ period, and 118 (30.6%) in the post-AJ period. Of these, 123 (31.9%) underwent CRRM, a median 42 (interquartile range: 11-54) days after the index cancer surgery. Rates of CRRM doubled following AJ's news, from 23.9% pre-AJ to 50.0% post AJ (p < 0.001). Rates of CRRM were found to decrease with increasing age at breast cancer (p < 0.001) and tumour TNM stage (p = 0.040), and to increase with the estimated lifetime risk of breast cancer (p < 0.001) and tumour grade (p = 0.015) on univariable analysis. After adjusting for these factors, the step-change increase in CRRM rates post-AJ remained significant (odds ratio: 9.61, p < 0.001). The AJ effect appears to have been associated with higher rates of CRRM amongst breast cancer patients with increased cancer risk. CRRM rates were highest amongst younger women and those with the highest lifetime risk profile. Clinicians need to be aware of how media news can impact on the delivery of cancer related services. Communicating objective assessment of risk is important when counselling women on the merits of risk-reducing surgery.

Long-Term Evaluation of Women Referred to a Breast Cancer Family History Clinic (Manchester UK 1987-2020).

Clinics for women concerned about their family history of breast cancer are widely established. A Family History Clinic was set-up in Manchester, UK, in 1987 in a Breast Unit serving a population of 1.8 million. In this review, we report the outcome of risk assessment, screening and prevention strategies in the clinic and propose future approaches. Between 1987-2020, 14,311 women were referred, of whom 6.4% were from known gene families, 38.2% were at high risk (≥30% lifetime risk), 37.7% at moderate risk (17-29%), and 17.7% at an average/population risk who were discharged. A total of 4168 (29.1%) women were eligible for genetic testing and 736 carried pathogenic variants, predominantly in BRCA1 and BRCA2 but also other genes (5.1% of direct referrals). All women at high or moderate risk were offered annual mammographic screening between ages 30 and 40 years old: 646 cancers were detected in women at high and moderate risk (5.5%) with a detection rate of 5 per 1000 screens. Incident breast cancers were largely of good prognosis and resulted in a predicted survival advantage. All high/moderate-risk women were offered lifestyle prevention advice and 14-27% entered various lifestyle studies. From 1992-2003, women were offered entry into IBIS-I (tamoxifen) and IBIS-II (anastrozole) trials (12.5% of invitees joined). The NICE guidelines ratified the use of tamoxifen and raloxifene (2013) and subsequently anastrozole (2017) for prevention; 10.8% women took up the offer of such treatment between 2013-2020. Since 1994, 7164 eligible women at ≥25% lifetime risk of breast cancer were offered a discussion of risk-reducing breast surgery and 451 (6.2%) had surgery. New approaches in all aspects of the service are needed to build on these results.

Aluminium in human breast tissue.

Aluminium is omnipresent in everyday life and increased exposure is resulting in a burgeoning body burden of this non-essential metal. Personal care products are potential contributors to the body burden of aluminium and recent evidence has linked breast cancer with aluminium-based antiperspirants. We have used graphite furnace atomic absorption spectrometry (GFAAS) to measure the aluminium content in breast biopsies obtained following mastectomies. The aluminium content of breast tissue and breast tissue fat were in the range 4-437 nmol/g dry wt. and 3-192 nmol/g oil, respectively. The aluminium content of breast tissue in the outer regions (axilla and lateral) was significantly higher (P=0.033) than the inner regions (middle and medial) of the breast. Whether differences in the regional distribution of aluminium in the breast are related to the known higher incidence of tumours in the outer upper quadrant of the breast remains to be ascertained.

Late toxicity is not increased in BRCA1/BRCA2 mutation carriers undergoing breast radiotherapy in the United Kingdom.

PURPOSE: To undertake the first substantial clinical study of breast radiotherapy toxicity in BRCA1 and BRCA2 mutation carriers in the United Kingdom. EXPERIMENTAL DESIGN: Acute and late radiation effects were evaluated in a retrospective study of 55 BRCA1 and BRCA2 mutation carriers treated with radiotherapy for breast cancer at four centers between 1983 and 2002. Individual matching with controls who had sporadic breast cancer was undertaken for age at diagnosis, time since completion of radiation, and treatment variables. Detailed assessments were undertaken by one examiner. Median follow-up was 6.75 years for carriers and 7.75 years for controls. Rates of late events (rib fractures, lung fibrosis, necrosis of soft tissue/bone, and pericarditis) as well as LENT-SOMA scores and clinical photography scores of breast size, shape, and skin telangiectasia were the primary end points. RESULTS: No increase in clinically significant late toxicity was seen in the mutation carriers. CONCLUSIONS: These data add substantial weight to the evidence that the outcomes in the treated breast from radiotherapy in women with BRCA1 or BRCA2 mutations are comparable with those in women with sporadic breast cancer.

Acute chemotherapy-related toxicity is not increased in BRCA1 and BRCA2 mutation carriers treated for breast cancer in the United Kingdom.

PURPOSE: To evaluate acute toxicity induced by chemotherapy for breast cancer in a retrospective study of 62 BRCA1/2 mutation carriers matched 1:1 with women who had treatment for sporadic disease in the United Kingdom between 1983 and 2003. EXPERIMENTAL DESIGN: All participants were interviewed by one of two researchers using standardized questionnaires, and their medical records were reviewed by one research nurse. The two main regimens received were cyclophosphamide, methotrexate, and fluorouracil and fluorouracil, epirubicin, and cyclophosphamide. The proportion of cases and controls receiving anthracycline-based treatment was equivalent, but fewer BRCA1 cases received this treatment than did BRCA2 mutation carriers. Toxicity was documented using the Eastern Cooperative Oncology Group Common Toxicity Criteria for hematologic, infective, and gastrointestinal toxicities. No increase in toxicity was seen in BRCA1/2 mutation carriers. RESULTS: The only significant difference was that neutropenia was less evident in BRCA2 mutation carriers than in either BRCA1 mutation carriers or controls. As a result, there was no requirement for dose reduction among BRCA2 mutation carriers, in contrast to 10 of 39 BRCA1 carriers and 16 of 62 controls (P = 0.02). CONCLUSIONS: This result has implications for therapy and indicates that women with mutations in BRCA1 and BRCA2 may be given the same doses of chemotherapy as noncarriers.

Using the Internet for information about breast cancer: a questionnaire-based study.

OBJECTIVES: To identify the proportion of breast cancer patients that used the Internet for breast cancer information; to classify patterns of use based on patient demographics; and to evaluate whether using the Internet for this purpose was beneficial or problematic. Also to recognize whether a specific demographic group was more likely to experience problems when using the Internet for breast cancer information. METHODS: A 10-item questionnaire was given to patients who attended the breast unit at the University Hospital of South Manchester between May and June 2011 following breast cancer treatment within the last 5 years. RESULTS: 200 questionnaires were completed. 50.5% of patients had used the Internet for breast cancer information, with younger (p<0.001) patients with a higher household income (p<0.001) being most likely to do so. The majority (73%) found it beneficial; however 31% had experienced problems. Ethnicity affected the likelihood of experiencing problems with white patients encountering fewer problems (25%) than non-white patients (64%) (p=0.008). CONCLUSION: A significant proportion of breast cancer patients will encounter difficulties when using the Internet for breast cancer information, particularly those from ethnic minorities. PRACTICE IMPLICATIONS: Health professionals need to include a discussion about Internet use in consultations with breast cancer patients.

The aluminium content of breast tissue taken from women with breast cancer.

The aetiology of breast cancer is multifactorial. While there are known genetic predispositions to the disease it is probable that environmental factors are also involved. Recent research has demonstrated a regionally specific distribution of aluminium in breast tissue mastectomies while other work has suggested mechanisms whereby breast tissue aluminium might contribute towards the aetiology of breast cancer. We have looked to develop microwave digestion combined with a new form of graphite furnace atomic absorption spectrometry as a precise, accurate and reproducible method for the measurement of aluminium in breast tissue biopsies. We have used this method to test the thesis that there is a regional distribution of aluminium across the breast in women with breast cancer. Microwave digestion of whole breast tissue samples resulted in clear homogenous digests perfectly suitable for the determination of aluminium by graphite furnace atomic absorption spectrometry. The instrument detection limit for the method was 0.48 µg/L. Method blanks were used to estimate background levels of contamination of 14.80 µg/L. The mean concentration of aluminium across all tissues was 0.39 µg Al/g tissue dry wt. There were no statistically significant regionally specific differences in the content of aluminium. We have developed a robust method for the precise and accurate measurement of aluminium in human breast tissue. There are very few such data currently available in the scientific literature and they will add substantially to our understanding of any putative role of aluminium in breast cancer. While we did not observe any statistically significant differences in aluminium content across the breast it has to be emphasised that herein we measured whole breast tissue and not defatted tissue where such a distribution was previously noted. We are very confident that the method developed herein could now be used to provide accurate and reproducible data on the aluminium content in defatted tissue and oil from such tissues and thereby contribute towards our knowledge on aluminium and any role in breast cancer.

Cyclooxygenase-2 inhibition does not improve the reduction in ductal carcinoma in situ proliferation with aromatase inhibitor therapy: results of the ERISAC randomized placebo-controlled trial.

PURPOSE: Tamoxifen reduces risk of recurrence after breast conservation surgery for ductal carcinoma in situ (DCIS), but no data exists on the effectiveness of aromatase inhibitors for DCIS. Cyclooxygenase-2 (COX-2) is overexpressed in DCIS, representing another potential therapeutic target. The aim of the study was to determine the effect of aromatase and/or COX-2 inhibition on epithelial proliferation and apoptosis in a presurgical study of estrogen receptor (ER)-positive DCIS. METHODS: Postmenopausal women with ER-positive DCIS diagnosed by core biopsy were randomized to a 2 x 2 design of either 14 days of exemestane or placebo and celecoxib, or placebo immediately before surgery. Paired baseline and end point biopsies were analyzed for proliferation (Ki67), apoptosis, human epidermal growth factor receptor 2 (HER2), COX-2, and progesterone receptor (PR) expression by immunohistochemistry. The primary end point was a decrease in Ki67 between diagnosis and surgical excision. RESULTS: Ninety women were randomized: all were ER positive, 49 (54%) had grade III tumors, and 29 (32%) were HER2 positive (3+). Exemestane reduced proliferation compared with placebo with a median reduction of 9% (95% confidence interval, 6-14; P < 0.001). Progesterone receptor was reduced by exemestane (mean decrease, 19%; 95% confidence interval, 9-28; P = 0.011). The effect of exemestane on proliferation was seen regardless of grade, HER2, or PR expression. Celecoxib had no effect on proliferation or apoptosis alone, or in combination with exemestane. CONCLUSIONS: Exemestane reduces proliferation in ER-positive DCIS. Aromatase inhibition is a potential alternative to tamoxifen in patients who have undergone breast conservation for ER-positive DCIS.

Randomized multicenter trial of sentinel node biopsy versus standard axillary treatment in operable breast cancer: the ALMANAC Trial.

BACKGROUND: Sentinel lymph node biopsy in women with operable breast cancer is routinely used in some countries for staging the axilla despite limited data from randomized trials on morbidity and mortality outcomes. We conducted a multicenter randomized trial to compare quality-of-life outcomes between patients with clinically node-negative invasive breast cancer who received sentinel lymph node biopsy and patients who received standard axillary treatment. METHODS: The primary outcome measures were arm and shoulder morbidity and quality of life. From November 1999 to October 2003, 1031 patients were randomly assigned to undergo sentinel lymph node biopsy (n = 515) or standard axillary surgery (n = 516). Patients with sentinel lymph node metastases proceeded to delayed axillary clearance or received axillary radiotherapy (depending on the protocol at the treating institution). Intention-to-treat analyses of data at 1, 3, 6, and 12 months after surgery are presented. All statistical tests were two-sided. RESULTS: The relative risks of any lymphedema and sensory loss for the sentinel lymph node biopsy group compared with the standard axillary treatment group at 12 months were 0.37 (95% confidence interval [CI] = 0.23 to 0.60; absolute rates: 5% versus 13%) and 0.37 (95% CI = 0.27 to 0.50; absolute rates: 11% versus 31%), respectively. Drain usage, length of hospital stay, and time to resumption of normal day-to-day activities after surgery were statistically significantly lower in the sentinel lymph node biopsy group (all P < .001), and axillary operative time was reduced (P = .055). Overall patient-recorded quality of life and arm functioning scores were statistically significantly better in the sentinel lymph node biopsy group throughout (all P < or = .003). These benefits were seen with no increase in anxiety levels in the sentinel lymph node biopsy group (P > .05). CONCLUSION: Sentinel lymph node biopsy is associated with reduced arm morbidity and better quality of life than standard axillary treatment and should be the treatment of choice for patients who have early-stage breast cancer with clinically negative nodes.
