Physical health-related quality of life trajectories over two years following breast cancer diagnosis in older women: a secondary analysis.

PURPOSE: To identify distinct trajectories of physical health-related quality of life (HRQoL) in older women over the first two years following breast cancer diagnosis, and to examine characteristics associated with trajectory group membership. METHODS: A secondary analysis of a longitudinal study of women diagnosed with stage I-III breast cancer who completed surveys within eight months of diagnosis and six, twelve, and eighteen months later that focuses on a subset of women aged ≥ 65 years (N = 145).Physical HRQoL was assessed using the Physical Component Score (PCS) of the SF-36 Health Survey. Finite mixture modeling identified distinct PCS trajectories. Multivariable logistic regression identified variables predictive of low PCS group membership. RESULTS: Two distinct patterns of PCS trajectories were identified. The majority (58%) of women had PCS above the age-based SF-36 population norms and improved slightly over time. However, 42% of women had low PCS that remained low over time. In multivariable analyses, older age, difficulty paying for basics, greater number of medical comorbidities, and higher body mass index were associated with low PCS group membership. Cancer treatment and psychosocial variables were not significantly associated. CONCLUSION: A large subgroup of older women reported very low PCS that did not improve over time. Older age, obesity, multiple comorbidities, and lower socioeconomic status may be risk factors for poorer PCS in women with breast cancer. Incorporating routine comprehensive geriatric assessments that screen for these factors may help providers identify older women at risk for poorer physical HRQoL post breast cancer treatment.

Factors associated with insomnia symptoms over three years among premenopausal women with breast cancer.

PURPOSE: We examined longitudinal trends and factors associated with insomnia over 3 years in a cohort of young breast cancer patients. METHODS: Women with stage I-III breast cancer at ≤ 45 years were recruited at five institutions from New York, Texas, and North Carolina, within 8 months of diagnosis (n = 836). Participants completed questionnaires every 6 months for 3 years. Linear mixed-effects models were used to examine insomnia over time, using the Women's Health Initiative Insomnia Rating Scale (WHIIRS). We evaluated the relations of insomnia with demographic (age, race, education, income, employment, marital status), clinical (cancer stage, histologic grade, chemotherapy, radiation, hormone therapy, surgery, tumor size, body mass index, hot flashes), and social/behavioral variables (smoking status, social support, physical activity, depressive symptoms). RESULTS: At baseline, 57% of participants met or exceeded the cut-off for clinical insomnia (WHIIRS score ≥ 9). Insomnia symptoms were most prevalent at baseline (p < 0.0001), but decreased significantly throughout follow-up (p < 0.001). However, 42% of participants still experienced insomnia symptoms 3 years after diagnosis. In multivariable models, older age (p = 0.02), hot flashes (p < 0.0001), and depressive symptoms (p < 0.0001) remained significantly associated with insomnia over time. CONCLUSIONS: Insomnia symptoms were most frequent closer to breast cancer diagnosis and treatment, but persisted for some women who were older and those reporting higher hot flashes and depressive symptoms. Survivorship care should include assessing insomnia symptoms, particularly during and immediately after primary treatment. Implementing early interventions for sleep problems may benefit young breast cancer survivors and improve their quality of life.

Feasibility and Clinical Utility of Prediction Models for Breast Cancer-Related Lymphedema Incorporating Racial Differences in Disease Incidence.

Importance: Breast cancer-related lymphedema (BCRL) is a common complication of axillary lymph node dissection (ALND) but can also develop after sentinel lymph node biopsy (SLNB). Several models have been developed to predict the risk of disease development before and after surgery; however, these models have shortcomings that include the omission of race, inclusion of variables that are not readily available to patients, low sensitivity or specificity, and lack of risk assessment for patients treated with SLNB. Objective: To create simple and accurate prediction models for BCRL that can be used to estimate preoperative or postoperative risk. Design, Setting, and Participants: In this prognostic study, women with breast cancer who underwent ALND or SLNB from 1999 to 2020 at Memorial Sloan Kettering Cancer Center and the Mayo Clinic were included. Data were analyzed from September to December 2022. Main Outcomes and Measures: Diagnosis of lymphedema based on measurements. Two predictive models were formulated via logistic regression: a preoperative model (model 1) and a postoperative model (model 2). Model 1 was externally validated using a cohort of 34 438 patients with an International Classification of Diseases diagnosis of breast cancer. Results: Of 1882 included patients, all were female, and the mean (SD) age was 55.6 (12.2) years; 80 patients (4.3%) were Asian, 190 (10.1%) were Black, 1558 (82.8%) were White, and 54 (2.9%) were another race (including American Indian and Alaska Native, other race, patient refused to disclose, or unknown). A total of 218 patients (11.6%) were diagnosed with BCRL at a mean (SD) follow-up of 3.9 (1.8) years. The BCRL rate was significantly higher among Black women (42 of 190 [22.1%]) compared with all other races (Asian, 10 of 80 [12.5%]; White, 158 of 1558 [10.1%]; other race, 8 of 54 [14.8%]; P < .001). Model 1 included age, weight, height, race, ALND/SLNB status, any radiation therapy, and any chemotherapy. Model 2 included age, weight, race, ALND/SLNB status, any chemotherapy, and patient-reported arm swelling. Accuracy was 73.0% for model 1 (sensitivity, 76.6%; specificity, 72.5%; area under the receiver operating characteristic curve [AUC], 0.78; 95% CI, 0.75-0.81) at a cutoff of 0.18, and accuracy was 81.1% for model 2 (sensitivity, 78.0%; specificity, 81.5%; AUC, 0.86; 95% CI, 0.83-0.88) at a cutoff of 0.10. Both models demonstrated high AUCs on external (model 1: 0.75; 95% CI, 0.74-0.76) or internal (model 2: 0.82; 95% CI, 0.79-0.85) validation. Conclusions and Relevance: In this study, preoperative and postoperative prediction models for BCRL were highly accurate and clinically relevant tools comprised of accessible inputs and underscored the effects of racial differences on BCRL risk. The preoperative model identified high-risk patients who require close monitoring or preventative measures. The postoperative model can be used for screening of high-risk patients, thus decreasing the need for frequent clinic visits and arm volume measurements.

Local Recurrence After Breast-Conserving Therapy in Patients With Multiple Ipsilateral Breast Cancer: Results From ACOSOG Z11102 (Alliance).

PURPOSE: Breast-conserving therapy (BCT) is the preferred treatment for unifocal breast cancer (BC). The oncologic safety of BCT for multiple ipsilateral breast cancer (MIBC) has not been demonstrated in a prospective study. ACOSOG Z11102 (Alliance) is a phase II, single-arm, prospective trial designed to evaluate oncologic outcomes in patients undergoing BCT for MIBC. PATIENTS AND METHODS: Women age 40 years and older with two to three foci of biopsy-proven cN0-1 BC were eligible. Patients underwent lumpectomies with negative margins followed by whole breast radiation with boost to all lumpectomy beds. The primary end point was cumulative incidence of local recurrence (LR) at 5 years with an a priori rate of clinical acceptability of <8%. RESULTS: Among 270 women enrolled between November 2012 and August 2016, there were 204 eligible patients who underwent protocol-directed BCT. The median age was 61 years (range, 40-87 years). At a median follow-up of 66.4 months (range, 1.3-90.6 months), six patients developed LR for an estimated 5-year cumulative incidence of LR of 3.1% (95% CI, 1.3 to 6.4). Patient age, number of sites of preoperative biopsy-proven BC, estrogen receptor status and human epidermal growth factor receptor 2 status, and pathologic T and N categories were not associated with LR risk. Exploratory analysis showed that the 5-year LR rate in patients without preoperative magnetic resonance imaging (MRI; n = 15) was 22.6% compared with 1.7% in patients with a preoperative MRI (n = 189; P = .002). CONCLUSION: The Z11102 clinical trial demonstrates that breast-conserving surgery with adjuvant radiation that includes lumpectomy site boosts yields an acceptably low 5-year LR rate for MIBC. This evidence supports BCT as a reasonable surgical option for women with two to three ipsilateral foci, particularly among patients with disease evaluated with preoperative breast MRI.

How Much Pain Will I Have After Surgery? A Preoperative Nomogram to Predict Acute Pain Following Mastectomy.

INTRODUCTION: Acute postoperative pain affects time to opioid cessation and quality of life, and is associated with chronic pain. Effective screening tools are needed to identify patients at increased risk of experiencing more severe acute postoperative pain, and who may benefit from multimodal analgesia and early pain management referral. In this study, we develop a nomogram to preoperatively identify patients at high risk of moderate-severe pain following mastectomy. METHODS: Demographic, psychosocial, and clinical variables were retrospectively assessed in 1195 consecutive patients who underwent mastectomy from January 2019 to December 2020 and had pain scores available from a post-discharge questionnaire. We examined pain severity on postoperative days 1-5, with moderate-severe pain as the outcome of interest. Multivariable logistic regression was performed to identify variables associated with moderate-severe pain in a training cohort of 956 patients. The final model was determined using the Akaike information criterion. A nomogram was constructed using this model, which also included a priori selected clinically relevant variables. Internal validation was performed in the remaining cohort of 239 patients. RESULTS: In the training cohort, 297 patients reported no-mild pain and 659 reported moderate-severe pain. High body mass index (p = 0.042), preoperative Distress Thermometer score ≥4 (p = 0.012), and bilateral surgery (p = 0.003) predicted moderate-severe pain. The resulting nomogram accurately predicted moderate-severe pain in the validation cohort (AUC =  0.735). CONCLUSIONS: This nomogram incorporates eight preoperative variables to provide a risk estimate of acute moderate-severe pain following mastectomy. Preoperative risk stratification can identify patients who may benefit from individually tailored perioperative pain management strategies and early postoperative interventions to treat pain and assist with opioid tapering.

Nodal Recurrence in Patients With Node-Positive Breast Cancer Treated With Sentinel Node Biopsy Alone After Neoadjuvant Chemotherapy-A Rare Event.

IMPORTANCE: Prospective trials have demonstrated sentinel lymph node (SLN) false-negative rates of less than 10% when 3 or more SLNs are retrieved in patients with clinically node-positive breast cancer rendered clinically node-negative with neoadjuvant chemotherapy (NAC). However, rates of nodal recurrence in such patients treated with SLN biopsy (SLNB) alone are unknown because axillary lymph node dissection (ALND) was performed in all patients, limiting adoption of this approach. OBJECTIVE: To evaluate nodal recurrence rates in a consecutive cohort of patients with clinically node-positive (cN1) breast cancer receiving NAC, followed by a negative SLNB using a standardized technique, and no further axillary surgery. DESIGN, SETTING, AND PARTICIPANTS: From November 2013 to February 2019, a cohort of consecutively identified patients with cT1 to cT3 biopsy-proven N1 breast cancer rendered cN0 by NAC underwent SLNB with dual tracer mapping and omission of ALND if 3 or more SLNs were identified and all were pathologically negative. Metastatic nodes were not routinely clipped, and localization of clipped nodes was not performed. The study was performed in a single tertiary cancer center. INTERVENTION: Omission of ALND in patients with cN1 breast cancer after NAC if 3 or more SLNs were pathologically negative. MAIN OUTCOME AND MEASURES: The primary outcome was the rate of nodal recurrence among patients with cN1 breast cancer treated with SLNB alone after NAC. RESULTS: Of 610 patients with cN1 breast cancer treated with NAC, 555 (91%) converted to cN0 and underwent SLNB; 234 (42%) had 3 or more negative SLNs and had SLNB alone. The median (IQR) age of these 234 patients was 49 (40-58) years; median tumor size was 3 cm; 144 (62%) were ERBB2 (formerly HER2)-positive, and 43 (18%) were triple negative. Most (212 [91%]) received doxorubicin-based NAC; 205 (88%) received adjuvant radiotherapy (RT), and 164 (70%) also received nodal RT. At a median follow-up of 40 months, there was 1 axillary nodal recurrence synchronous with local recurrence in a patient who refused RT. Among patients who received RT (n = 205), there were no nodal recurrences. CONCLUSIONS AND RELEVANCE: This cohort study found that in patients with cN1 disease rendered cN0 with NAC, with 3 or more negative SLNs with SLNB alone, nodal recurrence rates were low, without routine nodal clipping. These findings potentially support omitting ALND in such patients.

Pilot Study of Anti-Th2 Immunotherapy for the Treatment of Breast Cancer-Related Upper Extremity Lymphedema.

Recent studies suggest that Th2 cells play a key role in the pathology of secondary lymphedema by elaborating cytokines such as IL4 and IL13. The aim of this study was to test the efficacy of QBX258, a monoclonal IL4/IL13 neutralizing antibody, in women with breast cancer-related lymphedema (BCRL). We enrolled nine women with unilateral stage I/II BCRL and treated them once monthly with intravenous infusions of QBX258 for 4 months. We measured limb volumes, bioimpedance, and skin tonometry, and analyzed the quality of life (QOL) using a validated lymphedema questionnaire (Upper Limb Lymphedema 27, ULL-27) before treatment, immediately after treatment, and 4 months following treatment withdrawal. We also obtained 5 mm skin biopsies from the normal and lymphedematous limbs before and after treatment. Treatment was well-tolerated; however, one patient with a history of cellulitis developed cellulitis during the trial and was excluded from further analysis. We found no differences in limb volumes or bioimpedance measurements after drug treatment. However, QBX258 treatment improved skin stiffness (p < 0.001) and improved QOL measurements (Physical p < 0.05, Social p = 0.01). These improvements returned to baseline after treatment withdrawal. Histologically, treatment decreased epidermal thickness, the number of proliferating keratinocytes, type III collagen deposition, infiltration of mast cells, and the expression of Th2-inducing cytokines in the lymphedematous skin. Our limited study suggests that immunotherapy against Th2 cytokines may improve skin changes and QOL of women with BCRL. This treatment appears to be less effective for decreasing limb volumes; however, additional studies are needed.

Postdischarge Nonsteroidal Anti-Inflammatory Drugs Are not Associated with Risk of Hematoma after Lumpectomy and Sentinel Lymph Node Biopsy with Multimodal Analgesia.

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are increasingly used in ambulatory breast surgery. The risk of hematoma associated with intraoperative ketorolac is low, but whether concomitant routine discharge with NSAIDs increases the risk of hematoma is unclear. METHODS: We retrospectively identified patients who underwent lumpectomy and sentinel lymph node biopsy (SLNB), and compared the 30-day risk of hematoma between patients discharged with opioids (opioid period: January 2018-August 2018) and patients discharged with NSAIDs with or without opioids (NSAID period: January 2019-April 2020). The association between study period and hematoma risk was assessed using multivariable models. Covariates included intraoperative ketorolac, home aspirin, and race/ethnicity. During the NSAID period, a survey was used to assess analgesic consumption on postoperative days 1-5. RESULTS: In total, 2724 patients were identified: 858 (31%) in the opioid period and 1866 (69%) in the NSAID period. In the NSAID period, 867 (46%) received NSAIDs and opioids, and 999 (54%) received NSAIDs only. Receipt of intraoperative ketorolac was higher in the NSAID period (78 vs. 64%, P < 0.001). The risks of any hematoma (4.1 vs. 3.6%, P = 0.6) and reoperation for bleeding (0.5 vs. 0.6%, P = 0.8) were similar between groups. Study period was not associated with hematoma risk (odds ratio 0.87, 95% confidence interval 0.56-1.35, P = 0.5). Among survey respondents (41%), nonopioid analgesic consumption did not increase after opioids were removed from the discharge regimen (median, 6 pills/group, P = 0.06). CONCLUSIONS: NSAIDs are associated with a low risk of hematoma after lumpectomy and SLNB, and should be prescribed instead of opioids, unless contraindicated.

Patterns of invasive recurrence among patients originally treated for ductal carcinoma in situ by breast-conserving surgery versus mastectomy.

PURPOSE: Local recurrence after treatment of ductal carcinoma in situ (DCIS) with breast-conserving surgery (BCS) is more common than after mastectomy, but it is unclear if patterns of invasive recurrence vary by initial surgical therapy. Among patients with invasive recurrence after treatment for DCIS, we compared patterns of first recurrence between those originally treated with BCS vs. mastectomy. METHODS: From 2000 to 2016, women with an invasive recurrence occurring ≥ 6 months after initial treatment for DCIS were retrospectively identified. Clinicopathologic features and adjuvant treatment of the initial DCIS, as well as characteristics of first invasive recurrences, were compared between patients who had undergone BCS vs. mastectomy. RESULTS: 452 patients with an invasive recurrence after surgery for DCIS were identified: 367 patients (81%) had initially undergone BCS and 85 patients (19%) mastectomy. Patients originally treated with mastectomy were younger and were more likely to have had high grade, necrosis, and multifocal or multicentric DCIS (p < 0.001) compared with the BCS group. A higher proportion of invasive recurrences were local after BCS (93%; 343/367), whereas 88% (75/85) of recurrences after mastectomy were regional or distant (p < 0.001). The median time to first invasive recurrence was not different between surgical groups (BCS: 6.4 years vs. mastectomy: 5.5 years; p = 0.12). CONCLUSIONS: Among women who experienced a first invasive recurrence after treatment for DCIS, those who had originally undergone mastectomy more commonly presented with advanced disease compared to those treated with BCS, likely related to the absence of the breast and the higher risk profile of their initial DCIS.

Intraoperative Ketorolac is Associated with Risk of Reoperation After Mastectomy: A Single-Center Examination.

BACKGROUND: Although ketorolac is an effective adjunct for managing pain in the perioperative period, it is associated with a risk of postoperative bleeding. This study retrospectively investigated the association between ketorolac use and both reoperation and postoperative opioid use among mastectomy patients. METHODS: The study identified all women undergoing mastectomy (unilaterally or bilaterally) at our ambulatory surgery cancer center from January 2016 to June 2019. The primary outcome was reoperation for bleeding on postoperative day 0 or 1, and the secondary outcome was postoperative opioid use. The association between ketorolac and outcomes was assessed using multivariable regression models. The covariates were age, body mass index, breast reconstruction, bilateral surgery, peripheral nerve block, and preoperative antiplatelet and/or anticoagulation medication. RESULTS: A cohort of 3469 women were identified. Ketorolac was given to 1549 (45%) of the women, with 922 women (60%) receiving 30 mg and 627 women (40%) receiving 15 mg. The overall reoperation rate for bleeding was 3.1% (1.8% without ketorolac vs 4.8% with ketorolac). In the multivariable analysis, ketorolac was associated with a higher risk of reoperation [odds ratio (OR) 2.43; 95% confidence interval (CI) 1.60-3.70; P < 0.0001]. Ketorolac also was associated with a lower proportion of patients receiving any postoperative narcotic within 24 h (15 mg: OR 0.73; 95% CI 0.57-0.94; P = 0.014 vs 30 mg: OR 0.52; 95% CI 0.42-0.66; P < 0.0001). CONCLUSIONS: Ketorolac use decreased postoperative opioid use, but this benefit was outweighed by the increased risk of bleeding requiring reoperation. This finding led to a change in practice at the authors' center, with ketorolac no longer administered in the perioperative care of the mastectomy patient.

Routine Opioid Prescriptions Are Not Necessary After Breast Excisional Biopsy or Lumpectomy Procedures.

BACKGROUND: Opioid analgesics are overprescribed after surgery. In August 2018, the authors replaced routine discharge opioid prescription with a nonsteroidal anti-inflammatory drug (NSAID) for patients who had a lumpectomy or excisional biopsy (lump/ex). This study compared patient-reported post-discharge pain scores for patients treated before and after the change in routine discharge medication. METHODS: Patients were categorized based on treatment before and after a change in discharge medication as follows: study period 1 (routine opioids), study period 2 (routine NSAID). Pain severity was assessed with an electronic survey on postoperative days (PODs) 1 to 5. Multivariable generalized estimating equations tested the association between pain severity and discharge in the first versus the second study period. RESULTS: Lump/ex was performed for 1606 patients between December 2017 and June 2019. Of these patients, 789 (49%) reported pain scores and were analyzed (328 in study period 1, 461 in study period 2). Opioid prescription at discharge decreased from 96% in period 1 to 14% (95% confidence interval [CI], 11-18%) in period 2. Only 1% of the patients discharged with NSAID were later prescribed an opioid. The maximum reported pain score on any POD for all the patients was severe for 30 patients (3.8%), moderate for 217 patients (28%), mild for 430 patients (54%), and none for 112 patients (14%). The estimated risk for moderate or greater pain on POD 1 was 36% for period 1 and 34% for period 2. The proportion of patients reporting moderate or greater pain was nonsignificantly lower for the patients treated in period 2 (odds ratio [OR], 0.91; 95% CI 0.67-1.22; P = 0.5). CONCLUSIONS: For patients undergoing lump/ex, a clinically meaningful difference in reported post-discharge pain scores can be excluded with a change to routine NSAID at discharge. Patients undergoing lump/ex should not be routinely discharged with opioids.

Atypical ductal hyperplasia bordering on DCIS on core biopsy is associated with higher risk of upgrade than conventional atypical ductal hyperplasia.

PURPOSE: Upgrade rates of conventional ADH are reported at 10-30%; however, rates for ADH bordering on DCIS (ADH-BD) are largely unknown. We examined the upgrade rate of ADH-BD and core needle biopsy (CNB) features associated with upgrade. Surgical management in patients with concurrent ipsilateral breast cancer (BC) was also examined. METHODS: From 2000 to 2018, women with CNB diagnosis of ADH-BD were prospectively identified. Women with pure ADH-BD and concurrent ipsilateral ADH-BD/BC were analyzed separately, and upgrade rates were calculated. CNB features associated with upgrade and type of surgery were examined in women with pure ADH-BD; CNB features and concurrent pathology associated with upgrade were examined in women with ipsilateral BC. RESULTS: 108/236 (46%) patients with pure ADH-BD on CNB had DCIS (40%) or invasive carcinoma (6%) on surgical excision. DCIS or invasive carcinoma was more frequently found on excision of a mass that yielded ADH-BD on biopsy than excision of calcifications (65% vs 38%; p < 0.001). The breast conservation success rate was high (80%) in patients who upgraded, despite a high re-excision rate of 46%. The upgrade rate of ADH-BD in women with concurrent ipsilateral BC was 41%. Most women (94%) with ADH-BD in the same quadrant as the BC were candidates for breast conserving surgery, with a success rate of 89%. CONCLUSION: The upgrade rate for pure ADH-BD is significantly higher than that reported for women with conventional ADH, especially in women with a mass on imaging. The upgrade rate of concurrent ipsilateral ADH-BD and BC is similarly high. Excision with a margin of normal tissue and specimen inking should be routine to minimize the need for re-excision.

Changing the Default: A Prospective Study of Reducing Discharge Opioid Prescription after Lumpectomy and Sentinel Node Biopsy.

BACKGROUND: Whether routinely prescribed opioids are necessary for pain control after discharge among lumpectomy/sentinel node biopsy (Lump/SLNB) patients is unclear. We hypothesize that Lump/SLNB patients could be discharged without opioids, with a failure rate < 10%. This study prospectively examines outcomes after changing standard discharge prescription from an opioid/non-steroidal anti-inflammatory drug (NSAID) to NSAID/acetaminophen. PATIENTS AND METHODS: Standard discharge pain medication orders included opioids in the first 3-month study period and were changed to NSAID/acetaminophen in the second 3-month period. Patient-reported medication consumption and pain scores were collected by post-discharge survey. Frequency of discharge with opioid, NSAID/acetaminophen failure rate, opioid use, and pain scores were examined. RESULTS: From May to October 2019, 663 patients had Lump/SLNB: 371 in the opioid study period and 292 in the NSAID period. In the opioid period, 92% (342/371) of patients were prescribed an opioid at discharge; of 142 patients who documented opioid use on the survey, 86 (61%) used zero tablets. Among 56 (39%) patients who used opioids, the median number taken by POD 5 was 4. After the change to NSAID/acetaminophen, rates of opioid prescription decreased to 14% (41/292). The NSAID/acetaminophen failure rate was 2% (5/251). Among survey respondents, there was no significant difference in the maximum reported pain scores (POD 1-5) between the opioid period and the NSAID period (p = 0.7). CONCLUSIONS: In Lump/SLNB patients, a change to default discharge with NSAID/acetaminophen resulted in a 78% absolute reduction in opioid prescription, with a failure rate of 2% and no difference in patient-reported pain scores. Most Lump/SLNB patients can be discharged with NSAID/acetaminophen.

Cosmetic Outcomes Following Breast-Conservation Surgery and Radiation for Multiple Ipsilateral Breast Cancer: Data from the Alliance Z11102 Study.

BACKGROUND: Diagnoses of multiple ipsilateral breast cancer (MIBC) are increasing. Historically, the primary treatment for MIBC has been mastectomy due to concerns about in-breast recurrence risk and poor cosmetic outcome. The Alliance Z11102 study prospectively assessed cosmetic outcomes in women with MIBC treated with breast-conserving therapy (BCT). PATIENTS AND METHODS: Z11102 was a multicenter trial enrolling women with two or three separate sites of biopsy-proven malignancy separated by ≥ 2 cm within the same breast. Cosmetic outcome was a planned secondary endpoint. Data were collected with a four-point cosmesis survey (1 = excellent, 4 = poor) and the BREAST-Q (scored 0-100). All patients undergoing successful breast-conserving therapy were treated with whole-breast radiation. Associations were assessed with Chi square or Fisher's exact tests as appropriate. RESULTS: Cosmetic outcome data for 216 eligible women who completed therapy are included in this analysis. Of the 136 patients who completed the survey 2 years postoperatively, 70.6% (N = 96) felt the result was good or excellent, while 3.7% (N = 5) felt the result was poor. We found no significant differences in patient-reported cosmetic outcomes when stratifying by patient age, number of lesions (two or three), number of incisions, number of lumpectomies, or size of largest area of disease. Mean satisfaction score on the BREAST-Q was 77.2 at 6 months following whole-breast radiation and 73.7 at 3 years following surgery. CONCLUSIONS: BCT performed for MIBC results in good or excellent cosmesis for the majority of women. From a cosmetic perspective, BCT is a valid surgical approach to women with MIBC. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01556243.

Prevalence and correlates of job and insurance problems among young breast cancer survivors within 18 months of diagnosis.

BACKGROUND: The prevalence and correlates of job and insurance problems were examined among a cohort of young U.S. breast cancer survivors during the first 18-months following diagnosis. METHODS: Participants were 708 women diagnosed at ≤45 years with stage I-III breast cancer. 90% were non-Hispanic white, 76% were married/partnered and 67% had ≥4-year college degree. Univariable and multivariable logistic regression examined the associations between demographic, lifestyle and clinical factors with job and insurance problems. RESULTS: 18-months after diagnosis, 56% of participants worked full-time, 16% part-time, 18% were homemakers and/or students, 4.5% were unemployed, and 2.4% were disabled. The majority (86%) had private insurance. Job-related problems were reported by 40% of women, and included believing they could not change jobs for fear of losing health insurance (35.0%), being fired (2.3%), and being demoted, denied promotion or denied wage increases (7.8%). Greater job-related problems were associated with being overweight vs. under/normal weight (p = 0.006), income <$50,000/per year (p = 0.01), and working full-time vs. part-time (p = 0.003). Insurance problems were reported by 27% of women, and included being denied health insurance (2.6%), health insurance increases (4.3%), being denied health benefit payments (14.8%) or denied life insurance (11.4%). Insurance problems were associated with being under/normal weight vs. obese (p = 0.01), not being on hormone therapy (p < 0.001), and a tumor size > 5 cm vs. < 2 cm (p = 0.01). CONCLUSIONS: Young survivors experienced significant job- and insurance-related issues following diagnosis. To the extent possible, work and insurance concerns should be addressed prior to treatment to inform work expectations and avoid unnecessary insurance difficulties.

Treatment of Ductal Carcinoma in Situ: Considerations for Tailoring Therapy in the Contemporary Era.

PURPOSE OF REVIEW: Standard options for the treatment of ductal carcinoma in situ (DCIS) include breast-conserving surgery (BCS) alone; BCS with radiotherapy or endocrine therapy, or both; and mastectomy. Survival is excellent with all options, but rates of local recurrence (LR) vary, as do quality-of-life measures. Here we discuss treatment outcomes, risk factors for LR, and tools for risk estimation. RECENT FINDINGS: After BCS, radiotherapy reduces the risk of LR by half, and endocrine therapy reduces the risk by a third. Young age, inadequate margins, and greater volume of disease are associated with higher risk of LR after BCS, while young age, high grade, and microinvasion are associated with higher risk of locoregional recurrence after mastectomy. Clinical tools, including the Memorial Sloan Kettering Cancer Center (MSKCC) DCIS nomogram, provide LR risk estimates after BCS that appear more accurate than current genomic assays. The safety of active surveillance for seemingly low-risk patients remains uncertain. SUMMARY: Estimation of LR risk, utilizing a multitude of clinicopathologic and treatment factors, can help a woman balance that risk with her values and priorities, and allow her to choose the optimal treatment option for her.

Microscopic Extracapsular Extension in Sentinel Lymph Nodes Does Not Mandate Axillary Dissection in Z0011-Eligible Patients.

BACKGROUND: In the ACOSOG (American College of Surgeons Oncology Group) Z0011 trial and the AMAROS (After Mapping of the Axilla: Radiotherapy or Surgery?) trial, matted nodes with gross extracapsular extension (ECE), a risk factor for locoregional recurrence, were an indication for axillary lymph node dissection (ALND), but the effect of microscopic ECE (mECE) in the sentinel lymph nodes (SLNs) on recurrence was not examined. METHODS: Between 2010 and 2017, 811 patients with cT1-2N0 breast cancer and SLN metastasis were prospectively managed according to Z0011 criteria, with ALND for those with more than two positive SLNs or gross ECE. Management of mECE was not specified. In this study, we compare outcomes of patients with one to two positive SLNs with and without mECE, treated with SLN biopsy alone (n = 685). RESULTS: Median patient age was 58 years, and median tumor size was 1.7 cm. mECE was identified in 210 (31%) patients. Patients with mECE were older, had larger tumors, and were more likely to be hormone receptor positive and HER2 negative, have two positive SLNs, and receive nodal radiation. At a median follow-up of 41 months, no isolated axillary failures were observed. There were 11 nodal recurrences; two supraclavicular ± axillary, four synchronous with breast, and five with distant failure. The five-year rate of any nodal recurrence was 1.6% and did not differ by mECE (2.3% vs. 1.3%; p = 0.84). No differences were observed in local (p = 0.08) or distant (p = 0.31) recurrence rates by mECE status. CONCLUSIONS: In Z0011-eligible patients, nodal recurrence rates in patients with mECE are low after treatment with SLN biopsy alone, even in the absence of routine nodal radiation. The presence of mECE should not be considered a routine indication for ALND.

Risk of Contralateral Breast Cancer in Women with Ductal Carcinoma In Situ Associated with Synchronous Ipsilateral Lobular Carcinoma In Situ.

BACKGROUND: Lobular carcinoma in situ (LCIS) is a risk factor for breast cancer, but the effect of LCIS found in association with ductal carcinoma in situ (DCIS) is unknown. In this study, we compared contralateral breast cancer (CBC) and ipsilateral breast tumor recurrence (IBTR) rates among women with DCIS with or without synchronous ipsilateral LCIS treated with breast-conserving surgery (BCS). METHODS: DCIS patients undergoing BCS from 2000 to 2011 with a contralateral breast at risk were stratified by the presence or absence of synchronous ipsilateral LCIS with the index DCIS (DCIS + LCIS vs. DCIS). Those with contralateral, bilateral, or prior ipsilateral LCIS were excluded. Associations of patient, tumor, and treatment factors with CBC and IBTR were evaluated. RESULTS: Of 1888 patients identified, 1475 (78%) had DCIS and 413 (22%) had DCIS + LCIS. At median follow-up of 7.2 (range 0-17) years, 307 patients had a subsequent first breast event; 207 IBTR and 100 CBC. The 10-year cumulative incidence of IBTR was similar in both groups: 15.0% vs. 14.2% (log-rank, p = 0.8) for DCIS + LCIS vs. DCIS, respectively. The 10-year cumulative incidence of CBC was greater in the DCIS + LCIS group: 10.9% vs. 6.1% for DCIS (log-rank, p < 0.001). After adjustment for other factors, CBC risk remained higher in DCIS + LCIS compared with DCIS (hazard ratio 2.06, 95% confidence interval 1.36-3.11, p = 0.001); there was no significant difference in IBTR risk. CONCLUSIONS: Compared with DCIS alone, DCIS + LCIS is associated with similar IBTR risk but double the risk of CBC. This finding should inform treatment decisions, in particular regarding endocrine therapy for risk reduction.
