Assessment of Leptomeningeal Carcinomatosis Diagnosis, Management and Outcomes in Patients with Solid Tumors Over a Decade of Experience.

OBJECTIVE: Leptomeningeal carcinomatosis (LMC), a common complication of advanced malignancies, is associated with high morbidity and mortality, yet diagnosis and treatment decisions remain challenging. This study describes the diagnostic and treatment modalities for LMC and identifies factors associated with overall survival (OS). MATERIALS AND METHODS: We performed a single-institution retrospective study (registration #: OSU2016C0053) of 153 patients diagnosed with LMC treated at The Ohio State University, Comprehensive Cancer Center, (OSUCCC)-James between January 1, 2010 and December 31, 2015. RESULTS: Median age at diagnosis was 55.7 years, and 61% had Eastern Cooperative Oncology Group baseline performance status ≤1. Most common primary tumors were breast (43%), lung (26%), and cutaneous melanoma (10%). At presentation, most patients were stage III-IV (71%) with higher grade tumors (grade III: 46%). Metastases to bone (36%), brain (33%), and lung (12%) were the most common sites with a median of 0.5 years (range, 0-14.9 years) between the diagnosis of first metastasis and of LMC. 153 (100%) patients had MRI evidence of LMC. Of the 67 (44%) who underwent lumbar puncture (LP), 33 (22%) had positive cerebrospinal fluid (CSF) cytology. Most patients received radiotherapy for LMC (60%) and chemotherapy (93%) for either the primary disease or LMC. 28 patients received intrathecal chemotherapy, 22 of whom had a primary diagnosis of breast cancer. 98% died with median OS of all patients was 1.9 months (95% CI: 1.3-2.5 months). CONCLUSION: Despite improved treatments and targeted therapies, outcomes of LMC remain extremely poor. Positive CSF cytology was associated with lower OS in patients who had cytology assessed and specifically in patients with breast cancer. CSF cytology serves as an important indicator for prognosis and helps aid in developing individualized therapeutic strategies for patients with LMC.

An International Study on Ventricular Assist Device Program Models.

BACKGROUND: Advanced technology and improved outcomes have led to rapid growth of ventricular assist devices (VADs) throughout the world, but little exists regarding their structure. We sought to study trends in VAD programs on a global level. METHODS: We distributed a 26-question online survey to 321 individuals who work within those programs. Four categories of questions were formed: patient management, coordinator role, multidisciplinary support, and leadership. RESULTS: Fifty-eight surveys (47 United States, 11 international) were analyzed. The majority of programs cared for 26 to 100 device-assisted patients (62%), 26% cared for ≤25 patients, and 12% cared for ≥100 patients. Advanced practice providers (APPs) were used in 69% of programs as a device coordinator. In-hospital rounding was performed equally among the APPs and registered nurses. Most programs used a social worker (90%), nutritionist (74%), pharmacist (72%), palliative care (66%), and finance coordinator (64%). Less than half (43%) included a case manager and only 33% used a pharmacist. The program leader was identified as a cardiologist (31%) or surgeon (26%) or both equally (43%). CONCLUSION: This study demonstrates differences and similarities between VAD program structures. Additional research is warranted to evaluate the effect of program structure on outcomes, job satisfaction, and retention regions.

Features, Outcomes, and Management Strategies of Male Breast Cancer: A Single Institution Comparison to Well-Matched Female Controls.

OBJECTIVE: The primary objective of this study was to delineate differences in management, overall and distant disease-free survival in males diagnosed with breast cancer and treated at The Ohio State University Comprehensive Cancer Center as compared to comprehensively matched female subjects. Secondary objectives included assessment of clinical and histopathologic features and recurrence score, as measured by Oncotype DX and the modified Magee equation #2. MATERIALS AND METHODS: This single institution retrospective study compared male and comprehensively matched female patients (1:2) with stage I-III breast cancer between 1994 and 2014. Recurrence risk was estimated using a modified Magee equation. Overall survival and distant disease-free survival were estimated and compared using Kaplan-Meier and Log-rank methods. RESULTS: Forty-five male breast cancer patients were included (stage I: 26.7%; stage II: 53.3%; stage III: 20.0%; hormone receptor positive: 97.8%; human epidermal growth factor receptor 2 negative: 84.4%) with a median age of 63.8 (43.0-79.4) years at diagnosis. Intermediate and low recurrence scores were most common in male and female patients respectively; mean score was similar between groups (20.3 vs. 19.8). The proportion of male breast cancer patients treated with adjuvant chemotherapy and post-mastectomy radiation was lower compared to female patients (42.2% vs. 65.3%, p=0.013; 22.7% vs. 44.4%, p=0.030, respectively). Overall survival and distant disease-free survival between male and female patients were similar. CONCLUSION: Male breast cancer patient outcomes were similar compared to well-matched female patients suggesting that breast cancer specific factors are more prognostic than gender.

Efficacy of different dosing schedules of capecitabine for metastatic breast cancer: a single-institution experience.

Purpose Capecitabine is widely used as a single agent on a 21-day cycle in the management of metastatic breast cancer (MBC). Our primary objective was to compare the standard dosing of capecitabine (Arm A: days 1-14 on 21-day cycle) to biweekly dosing (Arm B: days 1-7 and 15-21 on 28-day cycle) using retrospective data analysis. Methods 166 patients with MBC treated with single agent capecitabine at The Ohio State University from 2002 to 2014 were considered eligible. Median time to treatment failure (TTF) and overall survival (OS) were estimated using Kaplan-Meier (KM) methods. KM curves were compared using log-rank tests with Holm's correction for multiplicity. Results Patients were grouped by dose schedule into one of three arms: Arm A (21-day cycle; capecitabine given at 1000 mg/m2 orally, twice daily on days 1-14 of 21-day cycle); Arm B (28-day cycle; capecitabine given at 1000 mg/m2 orally, twice daily on days 1-7 and 15-21 of 28-day cycle); and Arm C (changeover regimen where patients started on the 21-day cycle, but changed to a 28-day cycle for tolerability). No difference was found in TTF or OS for patients with MBC between those who received capecitabine on either standard dosing (Arm A) and those on a biweekly cycle (Arm B or C). Overall, 41% of patients required dose reduction. Conclusions Our single institution experience showed that alternate dosing of capecitabine (biweekly, 28-day cycle) may be a reasonable alternative to standard 21-day cycle with similar efficacy and fewer dose reductions.

Assessment of outcomes and novel immune biomarkers in metaplastic breast cancer: a single institution retrospective study.

BACKGROUND: Metaplastic breast cancer remains poorly characterized given its rarity and heterogeneity. The majority of metaplastic breast cancers demonstrate a phenotype of triple-negative breast cancer; however, differences in clinical outcomes between metaplastic breast cancer and triple-negative breast cancer in the era of third-generation chemotherapy remain unclear. METHODS: We compared the clinical outcomes between women with metaplastic breast cancer and women with triple-negative breast cancer diagnosed between 1994 and 2014. Metaplastic breast cancer patients were matched 1:3 to triple-negative breast cancer patients by stage and age at diagnosis. Distant disease-free survival (DDFS) and overall survival (OS) were estimated using Kaplan Meier methods and Cox proportional hazard regression models. Immune checkpoint markers were characterized by immunohistochemistry in a subset of samples. RESULTS: Forty-four metaplastic breast cancer patients (stage I 14%; stage II 73%; stage III 11%; stage IV 2%) with an average age of 55.4 (± 13.9) years at diagnosis. Median follow-up for the included metaplastic breast cancer and triple-negative breast cancer patients (n = 174) was 2.8 (0.1-19.0) years. The DDFS and OS between matched metaplastic breast cancer and triple-negative breast cancer patients were similar, even when adjusting for clinical covariates (DDFS: HR = 1.64, p = 0.22; OS: HR = 1.64, p = 0.26). Metaplastic breast cancer samples (n = 27) demonstrated greater amount of CD163 in the stroma (p = 0.05) and PD-L1 in the tumor (p = 0.01) than triple-negative breast cancer samples (n = 119), although more triple-negative breast cancer samples were positive for CD8 in the tumor than metaplastic breast cancer samples (p = 0.02). CONCLUSIONS: Patients with metaplastic breast cancer had similar outcomes to those with triple-negative breast cancer based on DDFS and OS. The immune checkpoint marker profile of metaplastic breast cancers in this study may prove useful in future studies attempting to demonstrate an association between immune profile and survival.

Fractional CO2 laser therapy for genitourinary syndrome of menopause for breast cancer survivors.

PURPOSE: Fractional CO2 laser therapy is an emerging treatment for genitourinary syndrome of menopause (GSM). The objective of this study was to determine the feasibility and preliminary efficacy of fractional CO2 laser therapy in breast cancer survivors. METHODS: This was a single arm feasibility study of breast cancer survivors with dyspareunia and/or vaginal dryness. Participants received three treatments of fractional CO2 laser therapy at 30-day intervals and returned for a 1-month follow-up. Feasibility was defined as treatment completion without serious adverse events (SAE) in 80% of patients. We collected data on the Vaginal Assessment Scale (VAS), the Female Sexual Function Index (FSFI), the Urinary Distress Index (UDI), and SAE. RESULTS: A total of 64 patients participated in the study. The majority of women had Estrogen receptor/Progesterone receptor (ER/PR) positive/Her2neu negative (n = 37; 63%), stage I (n = 32, 54%) or II (n = 19, 32%) breast cancer. Most were receiving endocrine therapy (n = 54, 92%), most commonly aromatase inhibitors (AI; n = 40, 68%). Fifty-nine (88.1%) of those enrolled completed all treatments according to protocol with no reported SAE. No patient withdrew due to SAE. The scores of the VAS (mean Δ - 0.99; 95% CI [- 1.19, - 0.79], p < 0.001)), FSFI (mean Δ 9.67; 95% CI [7.27, 12.1], p < 0.001), and UDI (mean Δ - 8.85; 95% CI [- 12.75, - 4.75], p < 0.001)) improved from baseline to follow-up. CONCLUSION: Fractional CO2 laser treatment for breast cancer survivors is feasible and appears to reduce GSM symptoms across treatment and follow-up.

Learning, Life, and Lactation: Knowledge of Breastfeeding's Impact on Breast Cancer Risk Reduction and Its Influence on Breastfeeding Practices.

Introduction: The protective effects of breastfeeding against developing breast cancer are well known; however, it is unknown whether women are aware of this breastfeeding benefit. Research Aim/Questions: The aim of this investigation was to determine whether mothers received information about breast cancer risk reduction during breastfeeding counseling and whether this knowledge affected their decision to initiate and sustain breastfeeding. Materials and Methods: The survey was conducted at The Ohio State University Comprehensive Cancer Center with women aged 18-50 who had at least one live birth. Participants were recruited through primary care practice and a national clinical research registry. Results: Six hundred sixty-seven (92%) of the 724 respondents breastfed. Over half of them (56%), that is, 407 women (60.4% Caucasian, 46.9% African American), were aware before their most recent childbirth that breastfeeding reduced the risk of breast cancer. Of the 407 women, 36.4% said this knowledge affected their decision to breastfeed. Of the 39 who did not breastfeed, 23 women (59.0%) responded that awareness of risk reduction would have influenced their decision to breastfeed. Only 120 of 724 respondents (16.6%) received this information from healthcare providers. Women with this knowledge breastfed longer than those without this knowledge (13.2 versus 9.3 months; p < 0.001). More Caucasian women (76.4%) breastfed any one child for more than 6 months compared with African American women (63.2%; p = 0.011; chi-squared test). Conclusion: While several factors affect the initiation and duration of breastfeeding, this study demonstrates that knowledge of association between breastfeeding and breast cancer risk reduction may influence breastfeeding practices. Our study illustrates the need for improved counseling for mothers by healthcare providers regarding this benefit.
