RESUMEN
Limited data exist regarding body composition and associated patient-reported outcomes for women with metastatic BC. Demographic, clinical, blood, and questionnaire data were collected to quantify body composition and explore associations with symptoms, inflammation, and quality of life (QOL) in 41 women with ER + metastatic BC. Diagnostic/surveillance computed tomography (CT) images including the third lumbar region (L3) were obtained to evaluate skeletal muscle (SM) quantity and quality, and abdominal adipose tissue. Frequencies, medians and interquartile ranges are presented, stratified by sarcopenia and obesity (Body mass index (BMI) ≥ 30.0 kg/m2). Overall, 34% (n = 14/41), 49% (n = 20/41), and 34% (n = 14) of women had sarcopenia, myosteatosis, and obesity, respectively. Handgrip strength was compromised in 24% of subjects (n = 10/41). Women with sarcopenia had significantly lower body weight (P = 0.01), BMI (P ≤ 0.001), and whole body SM (P < 0.001), yet reported greater engagement in leisure time exercises (P = 0.05) vs. nonsarcopenic women. Women with obesity had significantly higher levels of abdominal obesity (all values P < 0.0001) and serum biomarkers of inflammation (P values <0.06), yet lower QOL (P = 0.02) vs. women without obesity. The abPGSGA did not differentiate women with sarcopenia. Future interventions should test if improvements in body composition are associated with better outcomes for this vulnerable, emerging population.

We report a rare case of paraneoplastic neurological syndrome with dual seropositivity of anti-aquaporin-4 and myelin oligodendrocyte glycoprotein antibodies in a 40 year-old woman with metastatic triple-negative breast cancer. She received multiple lines of anti-neoplastic treatment, including immunotherapy with pembrolizumab, as well as cytotoxic chemotherapy. Paraneoplastic meningoencephalomyelitis developed 2 years after diagnosis of breast cancer and 1 year after discontinuation of immunotherapy with pembrolizumab. She first developed longitudinally extending transverse myelitis followed by left optic neuritis and meningoencephalitis with new enhancing lesions in the brain and spinal leptomeninges. Cerebrospinal fluid analysis during both episodes showed normal glucose and protein, and elevated white blood cell count. Cytology was negative for malignancy. Cerebrospinal fluid was positive for neuromyelitis optica immunoglobulin G antibody anti-aquaporin-4, and autoimmune myelopathy panel was positive for myelin oligodendrocyte glycoprotein antibody. The patient had significant clinical and radiographic improvement after completion of five cycles of plasmapheresis followed by intravenous immunoglobulin. She did not have recurrence of paraneoplastic syndrome with maintenance rituximab every 6 months and daily low-dose prednisone. She succumbed to progressive systemic metastatic disease 4.5 years after her breast cancer diagnosis. This case shows that these antibodies can occur concurrently and cause clinical features, such as both neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein antibody disease, in a patient with a singular type of cancer. We highlight the importance of testing for paraneoplastic etiology in cancer patients with radiographic menigoencephalomyelitis or meningitis with atypical symptoms of meningeal carcinomatosis and/or cerebrospinal fluid profile negative for leptomeningeal carcinomatosis.
RESUMEN
Objectives: Concurrent care is a unique care delivery system that allows patients to receive disease modifying treatments and other supportive interventions while also receiving the traditional benefits of hospice care. The objectives of our observational study were to examine health care utilization, use of cancer-directed therapies and palliative interventions, and location of death in patients enrolled in concurrent care. Methods: 72 hematology-oncology patients at the Hines Veteran's Affairs Medical Center (VAMC) who enrolled in concurrent care from 12/2018-4/2021 were reviewed. Data were summarized with descriptive statistics including medians and percentages. Results: A minority of patients received cytotoxic chemotherapy (27.8%), immunotherapy (20.8%), palliative radiation (20.9%), blood products (11.1%), or invasive pain procedures (4.2%). Patients also used fewer cancer-directed treatments as they approached end of life (24.4% within 30 days of death compared to 13.3% within 14 days of death). Most patients died at home (62.9%) or in inpatient hospice (12.9%) as opposed to the hospital (2.9%). Conclusions: A minority of concurrent care patients received cancer-directed therapies or additional types of health care interventions despite the option to do so. Cancer-directed treatment utilization also decreased as patients approached end of life. Patients enrolled in concurrent care were able to appreciate its benefits for longer, as the average length of stay on concurrent care was nearly 3 months.
RESUMEN
CONTEXT: The outcomes of specialty palliative care (PC) interventions for patients with hematologic malignancies (HMs) is under-investigated. OBJECTIVES: We performed a systematic review to evaluate the effect of PC interventions on patient- and caregiver- reported outcomes and healthcare utilization among adults with HMs (leukemia, myeloma, and lymphoma). METHODS: From database inception through September 10, 2020, we systematically searched PubMed, CINAHL, Embase, Scopus, Web of Science, and Cochrane Reviews using terms representing HMs and PC. Eligible studies investigated adults aged 18 years and older, were published in the English language, and contained original, quantitative, or qualitative data related to patient- and/or caregiver-centered outcomes and healthcare utilization. RESULTS: We screened 5345 studies;16 met inclusion criteria and found that specialty PC led to improved symptom management, decreased likelihood of inpatient death, decreased healthcare utilization, decreased cost of healthcare, and improved caregiver-reported outcomes. Patients with HM have a high need for PC which, though increasing over time, is often provided late in the clinical disease course. CONCLUSIONS: Specialty PC interventions improve healthcare outcomes for patients with HMs and should be implemented early and often. There remains a need for additional studies investigating PC use exclusively in patients with HMs.

PURPOSE: Optimal cancer care requires patient self-management and coordinated timing and sequence of interdependent care. These are challenging, especially in safety-net settings treating underserved populations. We evaluated the 4R Oncology model (4R) of patient-facing care planning for impact on self-management and delivery of interdependent care at safety-net and non-safety-net institutions. METHODS: Ten institutions (five safety-net and five non-safety-net) evaluated the 4R intervention from 2017 to 2020 with patients with stage 0-III breast cancer. Data on self-management and care delivery were collected via surveys and compared between the intervention cohort and the historical cohort (diagnosed before 4R launch). 4R usefulness was assessed within the intervention cohort. RESULTS: Survey response rate was 63% (422/670) in intervention and 47% (466/992) in historical cohort. 4R usefulness was reported by 79.9% of patients receiving 4R and was higher for patients in safety-net than in non-safety-net centers (87.6%, 74.2%, P = .001). The intervention cohort measured significantly higher than historical cohort in five of seven self-management metrics, including clarity of care timing and sequence (71.3%, 55%, P < .001) and ability to manage care (78.9%, 72.1%, P = .02). Referrals to interdependent care were significantly higher in the intervention than in the historical cohort along all six metrics, including primary care consult (33.9%, 27.7%, P = .045) and flu vaccination (38.6%, 27.9%, P = .001). Referral completions were significantly higher in four of six metrics. For safety-net patients, improvements in most self-management and care delivery metrics were similar or higher than for non-safety-net patients, even after controlling for all other variables. CONCLUSION: 4R Oncology was useful to patients and significantly improved self-management and delivery of interdependent care, but gaps remain. Model enhancements and further evaluations are needed for broad adoption. Patients in safety-net settings benefited from 4R at similar or higher rates than non-safety-net patients, indicating that 4R may reduce care disparities.

OBJECTIVE: Docetaxel and capecitabine are active agents in advanced gastric and gastroesophageal (GE) carcinomas. This multi-institutional phase II trial evaluates the combination of docetaxel and capecitabine as first- or second-line treatment in patients with advanced gastric and GE adenocarcinomas. METHODS: Patients who had received 1 or no prior chemotherapy regimens were eligible. The chemotherapy regimen consisted of a 21-day cycle with docetaxel 30 mg/m(2) administered on days 1 and 8 and capecitabine 825 mg/m(2) administered twice daily on days 1-14. The primary end point of the study was overall survival (OS). RESULTS: Forty patients were enrolled in the study; 39 received treatment and were evaluable for response and toxicity. The median patient age was 61 years (range 21-84); 8 patients had received prior chemotherapy in the advanced or metastatic setting. Grade 3/4 adverse events occurred in 15 patients (38%), including diarrhea in 5 patients (13%) and hand-foot syndrome in 5 patients (13%). The overall response rate was 32% [95% confidence interval (CI) 16.7-51.4]. The median time to progression and OS were 3.4 months (95% CI 2.7-5.8) and 10.7 months (95% CI 6.1-12.1), respectively. CONCLUSIONS: The regimen of docetaxel and capecitabine is a well-tolerated, easily administered and active outpatient regimen for advanced gastric and GE adenocarcinoma.

IMPORTANCE: Among patients who undergo the 21-gene assay (21-GA), 39% to 67% receive an intermediate risk result and may receive ambiguous treatment guidance. The 70-gene signature assay (70-GS) may be associated with physicians' treatment decisions in this population with early breast cancer. OBJECTIVE: To determine whether 70-GS findings are associated with physicians' decisions about adjuvant treatment and confidence in their recommendations and to evaluate the dichotomous (high- vs low-risk) and continuous distribution of 70-GS indices among this group of patients with intermediate risk. DESIGN, SETTING, AND PARTICIPANTS: The Prospective Study of MammaPrint in Breast Cancer Patients With an Intermediate Recurrence Score (PROMIS trial) was an impact study conducted from May 20, 2012, through December 31, 2015, that enrolled 840 patients with early-stage breast cancer and a 21-gene assay recurrence score of 18 to 30. Patients were treated in 58 US institutions. INTERVENTIONS: The 70-GS result was given to physicians before adjuvant treatment. MAIN OUTCOMES AND MEASURES: Change in physician treatment decision before vs after receiving the 70-GS result. With a treatment change of greater than 20%, the odds ratio (OR) was applied. RESULTS: Among the 840 patients who underwent 70-GS classification (mean age, 59 years; range, 27-93 years), 374 (44.5%) had a low-risk and 466 (55.5%) had a high-risk result. The distribution of 70-GS indices did not correlate with recurrence score within the 21-GA intermediate range, with 70-GS low- and high-risk patients observed at every recurrence score. A significant change in adjuvant treatment was associated with receiving the 70-GS classifications with an OR of 0.64 (95% CI, 0.50-0.82; McNemar test, P < .001) for all patients. Among the low-risk patients, 108 of 374 (28.9%) had chemotherapy removed from their treatment recommendation; among the high-risk patients, 171 of 466 (36.7%) had chemotherapy added. Results of the 70-GS were associated with the physician's adjuvant treatment recommendation; 409 high-risk patients (87.8%) were recommended to receive adjuvant chemotherapy, and 339 low-risk patients (90.6%) were recommended no chemotherapy. Physicians reported having greater confidence in their treatment recommendation in 660 cases (78.6%) based on 70-GS results. CONCLUSIONS AND RELEVANCE: The 70-GS provides clinically actionable information regarding patients classified as intermediate risk by the 21-GA and was associated with a change in treatment decision in 282 of these patients (33.6%). Chemotherapy was added or withheld by the treating physician based on the results of the 70-GS test. Physicians reported more confidence with their treatment recommendation after receiving 70-GS results.

OBJECTIVE: This study aimed to test the feasibility of a 12-month weight loss intervention using telephone-based counseling plus community-situated physical activity (PA) in female breast cancer (BC) and colorectal cancer (CRC) survivors. METHODS: This multisite cooperative group study enrolled sedentary, female, postmenopausal BC and CRC survivors with BMI ≥ 25 kg/m2 to receive 12-month fitness center memberships and telephone counseling encouraging 150 min/wk of PA and a 500-kcal/ddecrease in energy intake. Feasibility criteria included accrual, adherence, and retention. Target weight loss was ≥ 5%. RESULTS: Among 25 BC survivors, median baseline BMI was 37.2 (range: 27.7-54.6), accrual occurred in 10 months, 60% and 28% met diet and exercise goals, 80% provided 12-month measures, and average weight loss was 7.6% (95% CI: -3.9%, 19.2%). Among 23 CRC survivors, median BMI was 31.8 (range: 26.4-48.7), accrual occurred in 24 months, 61% and 17% met diet and exercise goals, 87% provided measures, and average weight loss was 2.5% (95% CI: -8.2%, 13.3%). CONCLUSIONS: It is feasible to recruit and retain BC survivors in a cooperative group diet and PA weight loss trial. BC survivors achieved clinically meaningful weight loss but did not meet a priori adherence goals. In CRC survivors, recruitment was more difficult, and the intervention was less effective.

Several randomized controlled trials of anti-estrogens, such as tamoxifen and aromatase inhibitors, have demonstrated up to a 50-65% decrease in breast cancerincidence among high-risk women. Approximately 15% of women, age 35-79 years, in the U.S. meet criteria for breast cancer preventive therapies, but uptake of these medications remain low. Explanations for this low uptake includelack of awareness of breast cancer risk status, insufficient knowledge about breast cancer preventive therapies among patients and physicians, and toxicity concerns. Increasing acceptance of pharmacologic breast cancer prevention will require effective communication of breast cancer risk, accurate representation about the potential benefits and side effects of anti-estrogens, targeting-specific high-risk populations most likely to benefit from preventive therapy, and minimizing the side effects of current anti-estrogens with novel administration and dosing options. One strategy to improve the uptake of chemoprevention strategies is to consider lessons learned from the use of drugs to prevent other chronic conditions, such as cardiovascular disease. Enhancing uptake and adherence to anti-estrogens for primary prevention holds promise for significantly reducing breast cancer incidence, however, this will require a significant change in our current clinical practice and stronger advocacy and awareness at the national level.
RESUMEN
Breast cancer remains the most common malignancy in women worldwide. Oestrogen levels appear to be associated with an increased risk for the development of breast cancer. The Early Breast Cancer Trialists' Cooperative Group reported in a 1998 meta-analysis of 37000 breast cancer patients in 55 randomized adjuvant trials that tamoxifen, a selective oestrogen receptor modulator, reduced the incidence of contralateral breast cancers by 47% at 5 years. Tamoxifen has been shown in numerous prevention studies to decrease the incidence of breast cancer in high-risk women. Overall, the tamoxifen prevention trials showed a 38% reduction in the incidence of breast cancer (95% CI 28-46; P<0.0001). In the largest risk-reduction trial, the Breast Cancer Prevention Trial conducted by the National Surgical Adjuvant Breast and Bowel Project, tamoxifen reduced the risk of invasive breast cancer by 49% (two-sided P<0.00001), and non-invasive breast cancer by 50% (P<0.002). The occurrence of oestrogen receptor-(OR)-positive tumours decreased by 69%. Tamoxifen reduces the risk of developing oestrogen receptor-positive tumours, but OR-negative tumours are not affected. Rare but life-threatening side-effects of tamoxifen include endometrial carcinoma, thromboembolic events and cerebrovascular events. Less serious side-effects include cataracts, vasomotor instability, nausea and vaginal discharge. Raloxifene, a second-generation selective oestrogen receptor modulator, is approved for treatment of osteoporosis in post-menopausal women in the USA but it is not currently approved for breast cancer prevention outside of a clinical trial. Prevention studies involving raloxifene and aromatase inhibitors are currently being conducted.

Purpose. Extrapulmonary small cell carcinoma affecting the anal canal is a rare and poorly understood entity which can, in its early stages, masquerade as benign anorectal disease such as hemorrhoids. Methods. We report a case of this rare malignancy which initially presented with hematochezia and anal pain. We also review the literature with regard to previously described cases and management strategies including the role of surgery. Results. Despite aggressive multidisciplinary treatment consisting of chemotherapy and radiation, the disease progressed rapidly with dissemination occurring only three months after completion of treatment. Because of the aggressive nature of this tumor, the treatment options for this almost universally fatal malignancy are often palliative in nature. Conclusion. Chemoradiotherapy is likely the most reasonable approach to extrapulmonary small cell carcinoma of the anal canal given its aggressiveness.

BACKGROUND: Cancer stem cells (CSCs) are believed to be responsible for breast cancer formation and recurrence; therefore, therapeutic strategies targeting CSCs must be developed. One approach may be targeting signaling pathways, like Notch, that are involved in stem cell self-renewal and survival. MATERIALS AND METHODS: Breast cancer stem-like cells derived from cell lines and patient samples were examined for Notch expression and activation. The effect of Notch inhibition on sphere formation, proliferation, and colony formation was determined. RESULTS: Breast cancer stem-like cells consistently expressed elevated Notch activation compared with bulk tumor cells. Blockade of Notch signaling using pharmacologic and genomic approaches prevented sphere formation, proliferation, and/or colony formation in soft agar. Interestingly, a gamma-secretase inhibitor, MRK003, induced apoptosis in these cells. CONCLUSION: Our findings support a crucial role for Notch signaling in maintenance of breast cancer stem-like cells, and suggest Notch inhibition may have clinical benefits in targeting CSCs.

PURPOSE: The 21-gene Recurrence Score (RS) assay has been validated to quantify the risk of distant recurrence in tamoxifen-treated patients with lymph node-negative, estrogen receptor-positive breast cancer and predict magnitude of chemotherapy benefit. This multicenter study was designed to prospectively examine whether RS affects physician and patient adjuvant treatment selection and satisfaction. PATIENTS AND METHODS: Before and after obtaining the 21-gene RS assay, medical oncologists stated their adjuvant treatment recommendation and confidence in it. Patients also indicated their treatment choice pre- and post-RS assay. Patients completed measures for decisional conflict, anxiety, and quality of life. RESULTS: Seventeen medical oncologists at one community and three academic practices consecutively enrolled 89 assessable patients. The medical oncologist treatment recommendation changed for 28 patients (31.%). Twenty-four patients (27%) changed their treatment decision. The largest change after the RS results was conversion from the medical oncologist's pretest recommendation for chemotherapy plus hormonal therapy (CHT) to post-test recommendation for hormone therapy (HT) in 20 cases (22.5%). Nine patients (10.1%) changed their treatment decision from CHT to HT. RS results increased medical oncologist confidence in their treatment recommendation in 68 cases (76%). Patient anxiety and decisional conflict were significantly lower after RS results. CONCLUSION: The results of this study indicate that the RS assay impacts medical oncologist adjuvant treatment recommendations, patient treatment choice, and patient anxiety.

Gastrointestinal stromal tumors are rare tumors of the gastrointestinal tract. Gastrointestinal stromal tumors involving the rectum are uncommon. We describe a case of a 43-year-old female with a gastrointestinal stromal tumor of the rectum who declined abdominoperineal resection. Neoadjuvant treatment with imatinib decreased her tumor size, permitting sphincter-sparing transanal excision. She had no evidence of disease for 24 months postoperatively until she recurred with lung metastases. Microdissection genotyping of the recurrent lesion revealed a deletion in exon 11. Further mutational analysis showed that her metastatic lesion was concordant with her primary rectal lesion, suggesting that systemic micrometastasis was previously present at initial diagnosis. Deletion in exon 11 predicts for response with imatinib treatment and is associated with a longer event-free and overall survival. Current studies are underway that may help us optimize the treatment for patients with gastrointestinal stromal tumors.
