RESUMEN
BACKGROUND: The clinical significance of nonclassic, lobular carcinoma in situ (NC-LCIS) at the surgical margin of excisions for invasive cancer is unknown. We sought to determine whether NC-LCIS at or near the margin in the setting of a concurrent invasive carcinoma is associated with risk of ipsilateral breast tumor recurrence (IBTR) and locoregional recurrence (LRR). METHODS: Patients with stage 0-III breast cancer and NC-LCIS who underwent lumpectomy between January 2010 and January 2022 at a single institution were retrospectively identified. NC-LCIS margins were stratified as <2 mm, ≥2 mm, or within shave margin. Rates of IBTR and LRR were examined. RESULTS: A total of 511 female patients (median age 60 years [interquartile range (IQR) 52-69]) with NC-LCIS and an associated ipsilateral breast cancer with a median follow-up of 3.4 years (IQR 2.0-5.9) were identified. Final margins for NC-LCIS were ≥2 mm in 348 patients (68%), <2 mm in 37 (7.2%), and within shave margin in 126 (24.6%). Crude incidence of IBTR was 3.3% (n = 17) and that of LRR was 4.9% (n = 25). There was no difference in the crude rate of IBTR by NC-LCIS margin status (IBTR rate: 3.7% ≥2 mm, 0% <2 mm, 3.2% within shave margin, p = 0.8) nor in LRR (LRR rate: 4.9% ≥2 mm, 2.7% <2 mm, 5.6% within shave margin, p = 0.9). CONCLUSIONS: For completely excised invasive breast cancers associated with NC-LCIS, extent of margin width for NC-LCIS was not associated with a difference in IBTR or LRR. These data suggest that the decision to perform reexcision of margin after lumpectomy should be driven by the invasive cancer, rather than the NC-LCIS margin.

OBJECTIVE: End-of-life caregiving is associated with poorer mental health compared with other caregiving. The objective of this study was to examine the association between contextual characteristics and appraisal factors on family caregivers' mental health and well-being. METHODS: Family hospice caregivers were recruited across four states using a non-probabilistic sampling approach. This study analyzed contextual (demographic, caregiving, economic) and appraisal factors (Medical Outcomes Study Social Support Survey, Zarit Burden Interview) on caregivers' anxiety and depression (Hospital Anxiety and Depression scale, and positive affect and well-being (Positive Affect and Well-being Scale). Hierarchical linear regression models were generated in SPSS version 24. RESULTS: Data from 102 family caregivers were analyzed. On average, participants were 58.93 years of age (SD = 14.24), mostly female (72.55%), spouses/partners (51.96%), and non-Hispanic White (78.43%). Most (75.49%) described their financial situation as comfortable or more than adequate. Younger age (B = -0.11, 95% CI = -0.18 to -0.05) and increased caregiving burden (B = 0.18, 95% CI = 0.09 to 0.27) were associated with increased anxiety, while lower perceived financial adequacy (B = -1.19, 95% CI = -2.07 to -0.32), lower social support (B = -0.04, 95% CI = -0.06 to -0.01), and increased caregiving burden (B = 0.15, 95% CI = 0.08-0.22) were associated with worsened depression. Greater social support (B = 0.10, 95% CI = 0.05-0.14) and lower caregiving burden (B = -0.19, 95% CI = -0.32 to -0.07) were associated with greater positive affect and well-being. CONCLUSIONS: Findings suggest significant impact of contextual factors on mental health and well-being, and support the need for holistic assessment of hospice caregivers' wellbeing and programs and policies providing social services and economic support to caregivers.

Family caregivers of home hospice cancer patients often experience burden and distress, which can be mitigated by perceived social support. However, less attention has been paid to the non-family sources of support within social networks, or to how sources of support may also be sources of stress. We describe support and stress in social networks of hospice family caregivers and identify caregiving characteristics associated with classes identified in our data. We collected demographic and psychosocial self-report data from family caregivers providing in-home hospice care for advanced cancer patients (N = 90). Caregivers also reported perceived support and stress from specific family and non-family relationships. We identified three classes with unique patterns of stress and support within caregivers' support networks using a latent class analysis. Classes include: 1) high support, low stress across family and non-family network members ("supportive"; 53% of caregivers); 2) high support, high stress across family and non-family network ("ambivalent maximizers"; 26%); and 3) high support, high stress across family network only ("family-focused ambivalent"; 21%). Caregivers in the ambivalent maximizer class reported more burden than caregivers in the supportive class (p = .024). This is one of the first studies to systematically explore the role of non-family support, as well as how stress and support co-occur within relationships and across networks. As informal support networks of hospice family caregivers are complex and multifaceted, understanding the patterns of support and stress across various network members is essential to offer services to more effectively manage caregiver burden.
RESUMEN
BACKGROUND: Because anal and rectal squamous cell carcinomas (R-SCCs and A-SCCs) share a common histology and an excellent response to chemoradiation, we hypothesized that R-SCC and A-SCC may represent a similar biological entity, and location would not affect clinical presentation and prognosis. METHODS: Patients diagnosed with R-SCC (n = 2881) and A-SCC (n = 21,854) were identified in the Surveillance, Epidemiology, and End Results database (1998-2013). R-SCCs were staged based on American Joint Committee on Cancer classification for A-SCC, and impact of location was analyzed accordingly. RESULTS: Compared to A-SCC, R-SCCs were more common in females (65% versus 48%, P < 0.001) and older patients (62 versus 56 yrs, P < 0.001). R-SCC presented with more advanced disease than A-SCC: mean size 4.2 versus 3.6 cm; T4 14% versus 5%; nodal involvement 20% versus 15%; and metastases 13% versus 6% (all P < 0.001). In multivariable analysis, R-SCCs and A-SCCs had similar disease-specific survival (DSS) for stages 0, I, and III; however, stage II R-SCC had significantly worse DSS than A-SCCs (P = 0.002). This was due to a greater proportion of T3 (>5 cm) R-SCC tumors (36% versus 27%, P < 0.001), which had a lower DSS than T2 (2-5 cm) tumors. Within T3 and T4 tumors, R-SCCs had lower DSS than A-SCCs. CONCLUSIONS: R-SCC presented with higher stages than A-SCC, suggesting a delayed diagnosis. Larger R-SCC (T3-T4) had worse survival compared to T3-4 A-SCC, which may be due to a combination of more advanced disease within-stage as well as the use of less efficacious therapeutic regimens. Therefore, location may represent a significant prognostic factor for SCC of the anorectal region.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. These NCCN Guidelines Insights summarize and provide context for the updated guidelines recommendations regarding hospice and end-of-life (EOL) care. Updates for 2017 include revisions to and restructuring of the algorithms that address important EOL concerns. These recommendations were revised to provide clearer guidance for oncologists as they care for patients with cancer who are approaching the transition to EOL care. Recommendations for interventions and reassessment based on estimated life expectancy were streamlined and reprioritized to promote hospice referrals and improved EOL care.

BACKGROUND: Rising incidence of papillary thyroid microcarcinomas (PTMC) has raised concerns for overdiagnosis. Utility of the American Thyroid Association Risk Stratification System (ATA-RSS) 2015 in predicting risk of disease recurrence in patients with PTMC was assessed. METHODS: Electronic health records of patients who underwent total thyroidectomy were queried. ATA-RSS 2015 risk stratification was performed on those with PTMC, and validity for predicting disease recurrence was calculated. RESULTS: With 10-year median follow up, recurrence was higher in PTMC patients with high/intermediate vs low ATA risk (33 â% vs 4 â%, p â= â0.002). Sensitivity of ATA-RSS for detecting recurrence was 60 â%, specificity 90 â%, PPV 33.3 â%, NPV 96.6 â%, and accuracy 88 â%. When microscopic extrathyroidal extension (ETE) was excluded as an intermediate risk criterion, PPV improved to 50 â% and accuracy improved to 92.5 â% CONCLUSIONS: ATA-RSS 2015 predicts recurrence in PTMC with high NPV but low PPV. Exclusion of microscopic ETE improved PPV, which may help prevent overtreatment.

PURPOSE: Use of artificial intelligence (AI) in cancer care is increasing. What remains unclear is how best to design patient-facing systems that communicate AI output. With oncologist input, we designed an interface that presents patient-specific, machine learning-based 6-month survival prognosis information designed to aid oncology providers in preparing for and discussing prognosis with patients with advanced solid tumors and their caregivers. The primary purpose of this study was to assess patient and caregiver perceptions and identify enhancements of the interface for communicating 6-month survival and other prognosis information when making treatment decisions concerning anticancer and supportive therapy. METHODS: This qualitative study included interviews and focus groups conducted between November and December 2022. Purposive sampling was used to recruit former patients with cancer and/or former caregivers of patients with cancer who had participated in cancer treatment decisions from Utah or elsewhere in the United States. Categories and themes related to perceptions of the interface were identified. RESULTS: We received feedback from 20 participants during eight individual interviews and two focus groups, including four cancer survivors, 13 caregivers, and three representing both. Overall, most participants expressed positive perceptions about the tool and identified its value for supporting decision making, feeling less alone, and supporting communication among oncologists, patients, and their caregivers. Participants identified areas for improvement and implementation considerations, particularly that oncologists should share the tool and guide discussions about prognosis with patients who want to receive the information. CONCLUSION: This study revealed important patient and caregiver perceptions of and enhancements for the proposed interface. Originally designed with input from oncology providers, patient and caregiver participants identified additional interface design recommendations and implementation considerations to support communication about prognosis.

Although sentinel lymph node biopsy is now the primary method of axillary staging and is therapeutic for patients with limited nodal disease, axillary lymph node dissection (ALND) is still necessary for staging in groups where sentinel lymph node biopsy has not been proven to be accurate and to maintain local control in those with a heavy axillary tumor burden. Additionally, newer approaches to systemic therapy tailored to risk level sometimes necessitate knowledge of the number of involved axillary nodes which can only be obtained with ALND. Ongoing trials will address whether there are additional circumstances where radiotherapy can replace ALND.

OBJECTIVES: To examine the relationships among family caregiver burden and workplace productivity and activity impairment among home hospice family caregivers of individuals with cancer who worked while providing end-of-life caregiving. SAMPLE & SETTING: Baseline data from a longitudinal study of communication between hospice providers and hospice family caregivers were used for this secondary analysis. METHODS & VARIABLES: Working family caregivers with complete workplace productivity and activity impairment data were included in this analysis (N = 30). Demographic data, caregiver burden, and workplace productivity and activity impairment were examined with descriptive statistics, correlation analysis, and hierarchical linear regressions. RESULTS: Hospice family caregivers were primarily White, female, married, and employed full-time. Caregiver burden levels were significantly positively associated with activity impairment, presenteeism, and work productivity loss. These relationships remained statistically significant when controlling for age. IMPLICATIONS FOR NURSING: Hospice and oncology nurses can support working hospice family caregivers by assessing for burden and associated workplace challenges, as well as by providing referrals for respite and community resources.

OBJECTIVES: To design an interface to support communication of machine learning (ML)-based prognosis for patients with advanced solid tumors, incorporating oncologists' needs and feedback throughout design. MATERIALS AND METHODS: Using an interdisciplinary user-centered design approach, we performed 5 rounds of iterative design to refine an interface, involving expert review based on usability heuristics, input from a color-blind adult, and 13 individual semi-structured interviews with oncologists. Individual interviews included patient vignettes and a series of interfaces populated with representative patient data and predicted survival for each treatment decision point when a new line of therapy (LoT) was being considered. Ongoing feedback informed design decisions, and directed qualitative content analysis of interview transcripts was used to evaluate usability and identify enhancement requirements. RESULTS: Design processes resulted in an interface with 7 sections, each addressing user-focused questions, supporting oncologists to "tell a story" as they discuss prognosis during a clinical encounter. The iteratively enhanced interface both triggered and reflected design decisions relevant when attempting to communicate ML-based prognosis, and exposed misassumptions. Clinicians requested enhancements that emphasized interpretability over explainability. Qualitative findings confirmed that previously identified issues were resolved and clarified necessary enhancements (eg, use months not days) and concerns about usability and trust (eg, address LoT received elsewhere). Appropriate use should be in the context of a conversation with an oncologist. CONCLUSION: User-centered design, ongoing clinical input, and a visualization to communicate ML-related outcomes are important elements for designing any decision support tool enabled by artificial intelligence, particularly when communicating prognosis risk.

BACKGROUND: Multidisciplinary Tumor Boards (MDT) are used to obtain input regarding cancer management. This study assessed the impact of our institutional Endocrine MDT. METHODS: MDT notes on patients with thyroid cancer treated during 2012-2018 were abstracted retrospectively from the electronic medical record. Management change (MC) was prospectively collected by the MDT coordinator. Biannual evaluations reviewed the impact of the MDT as observed by attendees. RESULTS: MC was recommended in 47 (15%) of 286 presentations, with additional imaging being the most frequent (43%). Presentation of recurrences were more likely to result in MC (24% vs. 13% initial, p = 0.03). Overall, 98% of attendees found the conference exceeded educational expectations. About 24% reported intending to use a more evidence/guideline-based approach after attending and this trend increased over time (p = 0.002). CONCLUSION: MDT presentations led to a higher rate of MC particularly in recurrent TC patients and increased evidenced-based practice for attendees.

INTRODUCTION: Lobular carcinoma in situ (LCIS), atypical ductal and lobular hyperplasia (AH) increase breast cancer risk. We examined risk management recommendations (RMR) and acceptance in AH/LCIS. METHODS: All patients with AH/LCIS on core needle biopsy from 2013 to 2016 at our institution were identified; cancer patients were excluded. Univariate and multivariate analysis examined factors associated with management. RESULTS: 98 % of patients were evaluated by breast surgeons and 53 % underwent risk model calculation (RC). 77 % had new RMR. RMR of MRI screening (MRI), genetic counselling (GC) and medical oncology (MO) referral were 41 %, 18 %, 77 %, respectively. MRI screening was more likely recommended in those with strong family history (p = 0.01), and high RC (p < 0.001). Uptake of at least one RMR did not occur in 84 % of patients. Use of RC correlated with MO acceptance (p = 0.049). CONCLUSIONS: Diagnosis of atypia has the potential to change risk management for most, however only 16 % of patients accepted all RMR.

BACKGROUND: Advance care planning (ACP) is recommended for older patients undergoing surgery. ACP consists of creating advance directives (ADs), identifying surrogate decision makers (SDMs), and documenting goals of care. We identified factors associated with documentation of preoperative ACP to identify opportunities to optimize ACP for older surgical patients. METHODS: This was a retrospective study of surgical patients ≥70 years old who underwent elective, high-risk abdominal procedures between 01/2015-08/2019. Clinical data were obtained from our institution's National Surgical Quality Improvement Project database. ACP metrics were extracted from the electronic medical record. We analyzed the data to identify patient factors associated with ACP metrics. We also analyzed whether ACP was more frequent for patients who experienced postoperative complications or death. RESULTS: 267/1,651 patients were included. 97 patients (36%) had an AD available on the day of surgery, 57 (21%) had an SDM identified, and 31 (12%) had a documented goals of care conversation. On multivariable analysis, older age and white race were associated with an increased likelihood of having an AD available on the day of surgery. Women were 1.7 times more likely to have an SDM (p = 0.02). No patient or surgeon factors were significantly associated with goals of care documentation. ACP was not performed more frequently in patients who experienced postoperative complications or death. CONCLUSION: In this series, ACP was not routinely documented for older patients undergoing major surgery. ACP was not more frequent in patients who experienced complications or death, demonstrating the importance of universal preoperative ACP in older patients.

BACKGROUND: Tall cell variant of papillary thyroid carcinoma is an aggressive subtype of papillary thyroid carcinoma. We examined expression of cancer stem cell markers in tall cell variant compared with other well-differentiated thyroid cancers. METHODS: Expression of cancer stem cell markers was examined in 572 thyroid tumors from The Cancer Genome Atlas Thyroid Cancer database and tall cell variant and papillary thyroid carcinoma tumors by immunohistochemistry. RESULTS: Expression of the PROM1 gene, encoding the cancer stem cell marker CD133, was elevated in tall cell variant compared to classic papillary thyroid carcinoma in a large cohort of unmatched samples from The Cancer Genome Atlas Thyroid Cancer database (P < .001). By immunohistochemistry in age and stage matched samples, CD133 protein was confirmed to be significantly increased in tall cell variant versus classic papillary thyroid carcinoma (P = .006). Analyzing all thyroid cancers, high PROM1 expression was associated with worse disease-specific survival. Optimal cutoffs were determined to define a tall cell variant-like cancer stem cell signature characterized by high PROM1, high ALDH1A3, and low CD24 expression. Classic papillary thyroid carcinoma with a tall cell variant-like gene signature had worse recurrence disease-free survival compared to classic papillary thyroid carcinoma with a non-tall cell variant signature (P = .02). CONCLUSION: Tall cell variant of papillary thyroid carcinoma has increased expression of cancer stem cell markers compared to classic papillary thyroid carcinoma. The tall cell variant-like cancer stem cell gene signature identified a molecular subtype of classic papillary thyroid carcinoma that has a worse recurrence-free survival.

Models that recapitulate the complexity of human tumors are urgently needed to develop more effective cancer therapies. We report a bank of human patient-derived xenografts (PDXs) and matched organoid cultures from tumors that represent the greatest unmet need: endocrine-resistant, treatment-refractory and metastatic breast cancers. We leverage matched PDXs and PDX-derived organoids (PDxO) for drug screening that is feasible and cost-effective with in vivo validation. Moreover, we demonstrate the feasibility of using these models for precision oncology in real time with clinical care in a case of triple-negative breast cancer (TNBC) with early metastatic recurrence. Our results uncovered a Food and Drug Administration (FDA)-approved drug with high efficacy against the models. Treatment with this therapy resulted in a complete response for the individual and a progression-free survival (PFS) period more than three times longer than their previous therapies. This work provides valuable methods and resources for functional precision medicine and drug development for human breast cancer.

BACKGROUND: Unanticipated admissions are a burden to the health care system. Over 400 000 outpatient laparoscopic cholecystectomies (LCs) are performed annually in the United States. The aim of this study is to identify causes of unanticipated admissions and modifiable risk factors. METHODS: Patients undergoing elective outpatient LCs were identified from the 2013-2015 American College of Surgeons National Surgical Quality Improvement Program database. RESULTS: A total of 69 376 patients underwent outpatient LC or LC+ intraoperative cholangiogram (IOC); 2027 (2.9%) were admitted after a median of 5 days (interquartile range 3-8). Admission rates varied by preoperative indications: pancreatitis (4.9%), gallstones with obstruction (3.9%), cholecystitis (3.0%), and gallstones without obstruction (2.6%) (P = .003). The most frequent causes were infection, retained stones, and other GI complications. Patients admitted for infection or cardiopulmonary complications were older with higher American Society of Anesthesiologists (ASA) (P < .01), while patients with pain and retained stones were younger with lower ASA (P < .01). Patients who underwent LC+IOC had a lower admission rate due to retained stones (.17% vs. .31% LC, P = .006). CONCLUSIONS: Unanticipated admissions following outpatient LC occur infrequently for diverse reasons usually within the first week after surgery. Associated factors are patient and disease related and not at all modifiable. In selected patients, increased IOC use may decrease admissions from retained stones.

BACKGROUND: Studies indicate that racial disparities exist in the presentation and outcomes of patients undergoing thyroidectomy for cancer and benign disease. We examined the relationship between race, pre-operative characteristics and outcomes in patients undergoing thyroidectomy for GD. METHODS: Patients were identified from the 2013-2016 American College of Surgeons NSQIP database using ICD-9/10 codes consistent with diffuse toxic goiter. RESULTS: AA patients were more likely to have an ASA classification of ≥3 (41% vs 30%, p < 0.001), a higher rate of CHF (2.1% vs 0.5%, p = 0.01), hypertension (46% vs 32%, p < 0.001) and dyspnea (10% vs 5%, p < 0.001) compared to Non-Hispanic Caucasians (NH-C) patients. Complications were higher in patients with ASA≥3 and CHF but not affected by race. CONCLUSIONS: Analysis of a national database of thyroidectomy for GD revealed a higher burden of preoperative comorbidities in AA patients compared to other races, although race was not an independent predictor of outcomes.

PURPOSE: Patients with cancer experience high rates of morbidity and unplanned health care utilization and may benefit from new models of care. We evaluated an adult oncology hospital at home program's rate of unplanned hospitalizations and health care costs and secondarily, emergency department (ED) use, length of hospital stays, and intensive care unit (ICU) admissions during the 30 days after enrollment. METHODS: We conducted a prospective, nonrandomized, real-world cohort comparison of 367 hospitalized patients with cancer-169 patients consecutively admitted after hospital discharge to Huntsman at Home (HH), a hospital-at-home program, compared with 198 usual care patients concurrently identified at hospital discharge. All patients met clinical criteria for HH admission, but those in usual care lived outside the HH service area. Primary outcomes were the number of unplanned hospitalizations and costs during the 30 days after enrollment. Secondary outcomes included length of hospital stays, ICU admissions, and ED visits during the 30 days after enrollment. RESULTS: Groups were comparable except that more women received HH care. In propensity-weighted analyses, the odds of unplanned hospitalizations was reduced in the HH group by 55% (odds ratio, 0.45, 95% CI, 0.29 to 0.70; P < .001) and health care costs were 47% lower (mean cost ratio, 0.53; 95% CI, 0.39 to 0.72; P < .001) over the 30-day period. Secondary outcomes also favored HH. Total hospital stay days were reduced by 1.1 days (P = .004) and ED visits were reduced by 45% (odds ratio, 0.55; 95% CI, 0.33 to 0.92; P = .022). There was no evidence of a difference in ICU admissions (P = .972). CONCLUSION: This oncology hospital at home program shows initial promise as a model for oncology care that may lower unplanned health care utilization and health care costs.
