RESUMO

PURPOSE: Stereotactic body radiation therapy (SBRT) has been emerging as an efficacious and safe treatment modality for early-stage hepatocellular carcinoma (HCC), but optimal fractionation regimens are unknown. This study aims to analyze published clinical tumor control probability (TCP) data as a function of biologically effective dose (BED) and to determine radiobiological parameters and optimal fractionation schemes for SBRT and hypofractionated radiation therapy of early-stage HCC. MATERIAL AND METHODS: Clinical 1- to 5-year TCP data of 4313 patients from 41 published papers were collected for hypofractionated radiation therapy at 2.5-4.5 Gy/fraction and SBRT of early-stage HCC. BED was calculated at isocenter using three representative radiobiological models developed per the Hypofractionated Treatment Effects in the Clinic (HyTEC) initiative. Radiobiological parameters were determined from a fit to the TCP data using the least χ2 method with one set of model parameters regardless of tumor stages or Child-Pugh scores A and B. RESULTS: The fits to the clinical TCP data for SBRT of early-stage HCC found consistent α/ß ratios of about 14 Gy for all three radiobiological models. TCP increases sharply with BED and reaches an asymptotic maximal plateau, which results in optimal fractionation schemes of least doses to achieve asymptotic maximal tumor control for SBRT and hypofractionated radiation therapy of early-stage HCC that are found to be model-independent. CONCLUSION: From the fits to the clinical TCP data, we presented the first determination of radiobiological parameters and model-independent optimal fractionation regimens in 1-20 fractions to achieve maximal tumor control whenever safe for SBRT and hypofractionated radiation therapy of early-stage HCC. The determined optimal fractionation schemes agree well with clinical practice for SBRT of early-stage HCC. However, most existing hypofractionated radiation therapy schemes of 3-5 Gy/fraction are not optimal, higher doses are required to maximize tumor control, further validation of these findings is essential with clinical TCP data.

RESUMO

Purpose: Radiotherapy (RT) is commonly used in the treatment of breast cancer and often, despite advances in fractionated dosing schedules, produces undesirable skin toxicity. The purpose of this study was to evaluate the feasibility of using a keratin-based topical cream, KeraStat® Cream (KC; KeraNetics, Inc., Winston Salem, NC, USA) to manage the symptoms of radiation dermatitis (RD) in breast cancer patients undergoing RT. Materials and Methods: A total of 24 subjects were enrolled on this single-center, randomized, open-label study. Participants were randomly assigned to KC or standard of care (SOC, patient's choice of a variety of readily available creams or moisturizers). Patients were asked to apply the assigned treatment to the irradiated area twice daily, beginning with day 1 of RT, through 30 days post-RT. The primary outcome was compliance of use. Secondary outcomes included safety and tolerability of KC, as well as RD severity assessed using the Radiation Therapy Oncology Group (RTOG) scale and the patient-reported Dermatology Life Quality Index (DLQI). Results: All subjects in the KC group were assessed as compliant with no adverse events. The rate of RTOG Grade 2 RD was lower in the KC group (30.8%) compared to the SOC group (54.5%, P = .408). At the final RT visit, the mean RTOG RD score was lower in the KC group (1.0) versus the SOC group (1.4). Similarly, patient-reported quality of life measured by the DLQI at the end of RT was improved in the KC group (mean 4.25, small effect) versus the SOC group (mean 6.18, moderate effect, P = .412). Conclusions: KC was safe and well tolerated with no adverse events. Though efficacy measures were not powered to draw definitive conclusions, trends and clinical assessments suggest that there is a benefit of using KC compared to SOC for breast cancer patients treated with RT, and a larger powered study for efficacy is warranted. Trial Registry: This clinical trial is registered as NCT03374995 titled KeraStat(R) Cream for Radiation Dermatitis.

RESUMO

Importance: Spine metastasis can be treated with high-dose radiation therapy with advanced delivery technology for long-term tumor and pain control. Objective: To assess whether patient-reported pain relief was improved with stereotactic radiosurgery (SRS) as compared with conventional external beam radiotherapy (cEBRT) for patients with 1 to 3 sites of vertebral metastases. Design, Setting, and Participants: In this randomized clinical trial, patients with 1 to 3 vertebral metastases were randomized 2:1 to the SRS or cEBRT groups. This NRG 0631 phase 3 study was performed as multi-institutional enrollment within NRG Oncology. Eligibility criteria included the following: (1) solitary vertebral metastasis, (2) 2 contiguous vertebral levels involved, or (3) maximum of 3 separate sites. Each site may involve up to 2 contiguous vertebral bodies. A total of 353 patients enrolled in the trial, and 339 patients were analyzed. This analysis includes data extracted on March 9, 2020. Interventions: Patients randomized to the SRS group were treated with a single dose of 16 or 18 Gy (to convert to rad, multiply by 100) given to the involved vertebral level(s) only, not including any additional spine levels. Patients assigned to cEBRT were treated with 8 Gy given to the involved vertebra plus 1 additional vertebra above and below. Main Outcomes and Measures: The primary end point was patient-reported pain response defined as at least a 3-point improvement on the Numerical Rating Pain Scale (NRPS) without worsening in pain at the secondary site(s) or the use of pain medication. Secondary end points included treatment-related toxic effects, quality of life, and long-term effects on vertebral bone and spinal cord. Results: A total of 339 patients (mean [SD] age of SRS group vs cEBRT group, respectively, 61.9 [13.1] years vs 63.7 [11.9] years; 114 [54.5%] male in SRS group vs 70 [53.8%] male in cEBRT group) were analyzed. The baseline mean (SD) pain score at the index vertebra was 6.06 (2.61) in the SRS group and 5.88 (2.41) in the cEBRT group. The primary end point of pain response at 3 months favored cEBRT (41.3% for SRS vs 60.5% for cEBRT; difference, -19 percentage points; 95% CI, -32.9 to -5.5; 1-sided P = .99; 2-sided P = .01). Zubrod score (a measure of performance status ranging from 0 to 4, with 0 being fully functional and asymptomatic, and 4 being bedridden) was the significant factor influencing pain response. There were no differences in the proportion of acute or late adverse effects. Vertebral compression fracture at 24 months was 19.5% with SRS and 21.6% with cEBRT (P = .59). There were no spinal cord complications reported at 24 months. Conclusions and Relevance: In this randomized clinical trial, superiority of SRS for the primary end point of patient-reported pain response at 3 months was not found, and there were no spinal cord complications at 2 years after SRS. This finding may inform further investigation of using spine radiosurgery in the setting of oligometastases, where durability of cancer control is essential. Trial Registration: ClinicalTrials.gov Identifier: NCT00922974.

RESUMO

INTRODUCTION: Smoking during breast radiotherapy (RT) may be associated with radiation-induced skin injury (RISI). We aimed to determine if a urinary biomarker of tobacco smoke exposure is associated with increased rates of RISI during and after breast RT. PATIENTS AND METHODS: Women with Stage 0-IIIA breast cancer treated with breast-conserving surgery or mastectomy followed by RT to the breast or chest wall with or without regional nodal irradiation were prospectively enrolled on a multicenter study assessing acute/late RISI. 980 patients with urinary cotinine (UCot) measurements (baseline and end-RT) were categorized into three groups. Acute and late RISI was assessed using the ONS Acute Skin Reaction scale and the LENT-SOMA Criteria. RESULTS: Late Grade 2+ and Grade 3+ RISI occurred in 18.2% and 1.9% of patients, respectively-primarily fibrosis, pain, edema, and hyperpigmentation. Grade 2+ late RISI was associated with UCot group (P= 006). Multivariable analysis identified UCot-based light smoker/secondhand smoke exposure (HR 1.79, P= .10) and smoking (HR 1.60, p = .06) as non-significantly associated with an increased risk of late RISI. Hypofractionated breast RT was associated with decreased risk of late RISI (HR 0.51, P=.03). UCot was not associated with acute RISI, multivariable analysis identified race, obesity, RT site/fractionation, and bra size to be associated with acute RISI. CONCLUSIONS: Tobacco exposure during breast RT may be associated with an increased risk of late RISI without an effect on acute toxicity. Smoking cessation should be encouraged prior to radiotherapy to minimize these and other ill effects of smoking.

RESUMO

METHODS: 63 patients with early stage endometrial carcinoma treated with VBT 30 Gy in three fractions to the vaginal surface were invited to participate. 18 patients enrolled. Vaginal length and diameter were measured using original VBT cylinders to assess change. Patients completed sexual function, QOL, and toxicity questionnaires. The assessment of patients' sexual function relative to national mean was calculated and reported by the Health Measures Scoring Service, a third party. RESULTS: Median length of time from VBT start until research visit was 3.6 years. Mean original vaginal length of the 18 women was 13.7 cm (Range: 11-18 cm); mean original diameter was 3.0 cm (Range: 2.5-3.5 cm). There was a significant decrease in vaginal length of 1.2 cm (p = 0.0005). There was a mean vaginal diameter decrease of 0.03 cm that was not significant. Toxicities were grade 1-2 and infrequent. There were no grade two acute toxicities, and 1 patient (5.6%) who had a chronic toxicity, diarrhea. 7 patients had evaluable sexual function responses. Reported sexual function was above the national mean in global satisfaction, interest, and lubrication (52.9, 50.2, and 56.2 percentile). Patients performed beneath national mean in the categories of orgasm and discomfort (3.1, 46.7 percentile) which was not correlated with the decrease in vaginal length. DISCUSSION/CONCLUSION: VBT resulted in significant vaginal shortening. Patients underperformed in the categories of orgasm and vaginal discomfort relative to national mean. This report adds to the scarce literature of objective data on sexual satisfaction and vaginal sequelae of VBT for endometrial carcinoma.

RESUMO

PURPOSE: Macrolides are a recommended treatment option for severe asthma, but data for "difficult-to-treat" asthma, the asthma-COPD "overlap" syndrome, and treatment duration beyond one year are lacking. We present long-term data from community practice experience providing insights for practice and research. METHODS: We report data from (1) baseline (pre-treatment) chart review of antibiotic-treated asthma patients and (2) follow-up telephone interviews documenting severe exacerbations (NIH criteria), Asthma Control Test (ACT) scores, and asthma controller use at baseline and follow-up, analyzed using a "before-after" model. RESULTS: A total of 101 patients (mean age 55.6 years (Sd 16.8), 66 females) were included. None had ever taken high dose inhaled corticosteroids and 79 (78.2%) were severely uncontrolled (ACT score ≤15) before treatment. Coexisting COPD was present in 62 (61.4%) patients. Azithromycin or azithromycin plus doxycycline was primarily prescribed with a median treatment duration of 12 months and median follow-up duration of 22 months. Severe exacerbations in the month before treatment occurred in 50.5% vs 17.8% at follow-up (P<0.0001). Mean ACT score increased from 12.2 to 20.6 (P<0.0001). The number of patients taking controller medications decreased (P<0.0001 for inhaled corticosteroids; P<0.001 for long-acting beta agonist/long-acting muscarinic antagonist; P<0.05 for leukotriene receptor antagonists). Of the 79 severely uncontrolled patients, 51 (64.6%) became controlled at follow-up, and of these 51, 27 (52.9%) continued to take antibiotics while 24 (47.1%) had discontinued antibiotics earlier yet remained controlled. CONCLUSION: Antibiotic treatment may be beneficial in a significant proportion of "difficult to treat" asthma patients beyond one year, including some patients with the overlap syndrome and/or who fail to meet criteria for refractoriness.

RESUMO

To determine the impact of radiation therapy (XRT) in addition to trastuzumab (TZB) adjuvant chemotherapy for HER2+ breast cancer on left ventricular systolic function, we assessed demographics, oncologic treatment history including XRT exposure, and serial measurements of left ventricular ejection fraction (LVEF) in 135 consecutively identified women receiving TZB for treatment of adjuvant breast cancer. Longitudinal mixed effects models were fit to identify baseline to treatment changes in LVEF among those receiving TZB with or without concomitant anthracycline or XRT. Women averaged 53 ± 3 years in age, 77% were white, 62% patients had 1 or more cardiovascular risk factors at baseline, and mean duration of TZB was 11 ± 5 months. Seventy-seven women were treated with XRT and received between 4000 and 5500 cGy of radiation. The LVEF declined by an average of 3.4% after 1 year for those in the study. Relative to baseline upon completion of adjuvant TZB, LVEF remained reduced for those receiving anthracycline with or without XRT (p=0.002 for both), or XRT alone (p=0.002), but not in those without these therapies. Amongst patients treated only with XRT and TZB, LVEF declined 3.1% on average in those with left-sided disease and 6.9% on average in those with right-sided disease (p= 0.06, p= 0.008 respectively). Among women receiving TZB for adjuvant treatment of HER-2 positive breast cancer, the administration of XRT, anthracycline, or the combination of the 2 is associated with a persistent post-treatment as opposed to a temporary treatment related decline in LVEF.

RESUMO

IMPORTANCE: Mastectomy is standard for recurrence of breast cancer after breast conservation therapy with whole breast irradiation. The emergence of partial breast irradiation led to consideration of its application for reirradiation after a second lumpectomy for treatment of recurrence of breast cancer in the ipsilateral breast. OBJECTIVES: To assess the effectiveness and adverse effects of partial breast reirradiation after a second lumpectomy and whether the treatment is an acceptable alternative to mastectomy. DESIGN, SETTING, AND PARTICIPANTS: The NRG Oncology/Radiation Therapy Oncology Group 1014 trial is a phase 2, single-arm, prospective clinical trial of 3-dimensional, conformal, external beam partial breast reirradiation after a second lumpectomy for recurrence of breast cancer in the ipsilateral breast after previous whole breast irradiation. The study opened on June 4, 2010, and closed June 18, 2013. Median follow-up was 5.5 years. This analysis used all data received at NRG Oncology through November 18, 2018. Eligible patients experienced a recurrence of breast tumor that was less than 3 cm and unifocal in the ipsilateral breast more than 1 year after breast-conserving therapy with whole breast irradiation and who had undergone excision with negative margins. INTERVENTIONS: Adjuvant partial breast reirradiation, 1.5 Gy twice daily for 30 treatments during 15 days (45 Gy), using a 3-dimensional conformal technique. MAIN OUTCOMES AND MEASURES: The main outcomes of the present study were the predefined secondary study objectives of recurrence of breast cancer in the ipsilateral breast, late adverse events (>1 year after treatment), mastectomy incidence, distant metastasis-free survival, overall survival, and circulating tumor cell incidence. RESULTS: A total of 65 women were enrolled, with 58 evaluable for analysis (mean [SD] age, 65.12 [9.95] years; 48 [83%] white). Of the recurrences of breast cancer in the ipsilateral breast, 23 (40%) were noninvasive and 35 (60%) were invasive. In all 58 patients, 53 (91%) had tumors 2 cm or smaller. All tumors were clinically node negative. A total of 44 patients (76%) tested positive for estrogen receptor, 33 (57%) for progesterone receptor, and 10 (17%) for ERBB2 (formerly HER2 or HER2/neu) overexpression. Four patients had breast cancer recurrence, with a 5-year cumulative incidence of 5% (95% CI, 1%-13%). Seven patients underwent ipsilateral mastectomies for a 5-year cumulative incidence of 10% (95% CI, 4%-20%). Both distant metastasis-free survival and overall survival rates were 95% (95% CI, 85%-98%). Four patients (7%) had grade 3 and none had grade 4 or higher late treatment adverse events. CONCLUSIONS AND RELEVANCE: For patients experiencing recurrence of breast cancer in the ipsilateral breast after lumpectomy and whole breast irradiation, a second breast conservation was achievable in 90%, with a low risk of re-recurrence of cancer in the ipsilateral breast using adjuvant partial breast reirradiation. This finding suggests that this treatment approach is an effective alternative to mastectomy.

RESUMO

PURPOSE: Diabetes imposes a significant economic burden on employers, particularly when including productivity costs. Given the great interest on multicomponent lifestyle interventions in these individuals, we assessed the short-term and long-term efficacy of a structured lifestyle modification program, My Unlimited Potential, among employees with diabetes of Baptist Health South Florida (BHSF), a large non-for profit health-care system. DESIGN: This is a pre- and post-effectiveness of a workplace health promotion program. SETTING: Worksite intervention at BHSF. PARTICIPANTS: The study analyzed the data of 93 employees with diabetes involved in a worksite wellness program after completion of a year long program. INTERVENTION: The intervention was an intense lifestyle modification program that was targeted to the individual needs of the participants. MEASURES: Cardimetabolic risk factors such as body mass index (BMI), weight, systolic blood pressure, diastolic blood pressure, glycated hemoglobin, total cholesterol, triglycerides, high-sensitivity C-reactive protein, low-density lipoprotein, high-density lipoprotein, and maximal oxygen consumption. ANALYSIS: Paired 2-sample t tests for means and descriptive statistics were used. RESULTS: A mean decrease of 0.6 percentage points was observed in HbA1c values from baseline to 12 months. Weight, BMI, blood pressure, and lipid profile improved significantly after 12 months. CONCLUSION: This study suggests worksites with existing health promotion programs, and health-care staff can effectively deliver a diabetes prevention program that appears to have a long-term impact on employee health.

RESUMO

INTRODUCTION: Radiation-induced cognitive decline (RICD) is a late effect of radiotherapy (RT) occurring in 30-50% of irradiated brain tumor survivors. In preclinical models, pioglitazone prevents RICD but there are little safety data on its use in non-diabetic patients. We conducted a dose-escalation trial to determine the safety of pioglitazone taken during and after brain irradiation. METHODS: We enrolled patients > 18 years old with primary or metastatic brain tumors slated to receive at least 10 treatments of RT (≤ 3 Gy per fraction). We evaluated the safety of pioglitazone at 22.5 mg and 45 mg with a dose-escalation phase and dose-expansion phase. Pioglitazone was taken daily during RT and for 6 months after. RESULTS: 18 patients with a mean age of 54 were enrolled between 2010 and 2014. 14 patients had metastatic brain tumors and were treated with whole brain RT. Four patients had primary brain tumors and received partial brain RT and concurrent chemotherapy. No DLTs were identified. In the dose-escalation phase, there were only three instances of grade ≥ 3 toxicity: one instance of neuropathy in a patient receiving 22.5 mg, one instance of fatigue in a patient receiving 22.5 mg and one instance of dizziness in a patient receiving 45 mg. The attribution in each of these cases was considered "possible." In the dose-expansion phase, nine patients received 45 mg and there was only one grade 3 toxicity (fatigue) possibly attributable to pioglitazone. CONCLUSION: Pioglitazone was well tolerated by brain tumor patients undergoing RT. 45 mg is a safe dose to use in future efficacy trials.

RESUMO

PURPOSE/OBJECTIVES: Stereotactic radiosurgery (SRS) is used as a treatment option for breast cancer brain metastases. It is unclear what factors predict neurologic death for these patients. MATERIALS/METHODS: A total of 128 patients with breast cancer brain metastases were treated with upfront SRS alone in this study. Survival was estimated using the Kaplan-Meier method. Clinicopathologic factors evaluated included age, ER/PR status, Her2 status, numbers of brain metastases treated, minimum SRS dose, disease-specific GPA, extracranial disease status and systemic disease burden. RESULTS: ER or PR positivity was associated with a trend towards decreased neurologic death (subdistribution hazard ratio (sHR) = 0.54, p=0.06). Factors associated with non-neurologic death include extracranial disease status (sHR = 2.02, p=0.02) and dose (sHR = 1.11, p=0.02); Her2-positivity was associated with reduced hazard of non-neurologic death (sHR 0.52, p=0.05). CONCLUSIONS: ER/PR positivity was associated with a trend towards less neurologic death. HER2 positivity was associated with a trend towards less non-neurologic death.

RESUMO

Purpose This study examined an inflammatory biomarker, high-sensitivity C-reactive protein (hsCRP), in radiotherapy (RT)-induced early adverse skin reactions or toxicities in breast cancer. Patients and Methods Between 2011 and 2013, 1,000 patients with breast cancer who underwent RT were evaluated prospectively for skin toxicities through the National Cancer Institute-funded Wake Forest University Community Clinical Oncology Program Research Base. Pre- and post-RT plasma hsCRP levels and Oncology Nursing Society skin toxicity criteria (0 to 6) were used to assess RT-induced skin toxicities. Multivariable logistic regression analyses were applied to ascertain the associations between hsCRP and RT-induced skin toxicities after adjusting for potential confounders. Results The study comprised 623 white, 280 African American, 64 Asian/Pacific Islander, and 33 other race patients; 24% of the patients were Hispanic, and 47% were obese. Approximately 42% and 15% of patients developed RT-induced grade 3+ and 4+ skin toxicities, respectively. The hsCRP levels differed significantly by race and body mass index but not by ethnicity. In multivariable analysis, grade 4+ skin toxicity was significantly associated with obesity (odds ratio [OR], 2.17; 95% CI, 1.41 to 3.34], post-RT hsCRP ≥ 4.11 mg/L (OR, 1.61; 95% CI, 1.07 to 2.44), and both factors combined (OR, 3.65; 95% CI, 2.18 to 6.14). Above-median post-RT hsCRP (OR, 1.93; 95% CI, 1.03 to 3.63), and change in hsCRP (OR, 2.80; 95% CI, 1.42 to 5.54) were significantly associated with grade 4+ skin toxicity in nonobese patients. Conclusion This large prospective study is the first to our knowledge of hsCRP as an inflammatory biomarker in RT-induced skin toxicities in breast cancer. We demonstrate that nonobese patients with elevated RT-related change in hsCRP levels have a significantly increased risk of grade 4+ skin toxicity. The outcomes may help to predict RT responses and guide decision making.

RESUMO

Prospective studies have shown equal outcomes after mastectomy or breast conservation in patients with invasive breast cancer; however, many of these studies excluded elderly patients. We identified patients in their eighties and nineties with clinical stage 0 to II breast cancer undergoing mastectomy or lumpectomy with or without radiation from the prospective sentinel lymph node database at Wake Forest Baptist Health and analyzed their treatment and survival. Of 92 patients, 24 (26.1%) underwent mastectomy, 22 (23.9%) lumpectomy with radiation, and 46 (50.0%) lumpectomy alone. Significant differences were noted in tumor size (P = 0.018), nodal status (P = 0.013), and stage (P = 0.011) between the groups. Only 7.6 per cent of patients had chemotherapy, whereas 51.1 per cent took antiestrogen therapy. Recurrence occurred in 11 patients. In univariate analysis, overall survival did not differ by surgery. Age was the only factor that increased risk of death (HR = 1.19, P = 0.028). In this age group, neither tumor factors nor the type of local treatment significantly influenced overall survival. Octogenarians and nonagenarians with early-stage breast cancer undergoing breast-conserving surgery with or without radiation have equivalent survival to patients having a mastectomy.

RESUMO

PURPOSE: To determine the associated toxicity, tolerance, and safety of partial-breast reirradiation. METHODS AND MATERIALS: Eligibility criteria included in-breast recurrence occurring >1 year after whole-breast irradiation, <3 cm, unifocal, and resected with negative margins. Partial-breast reirradiation was targeted to the surgical cavity plus 1.5 cm; a prescription dose of 45 Gy in 1.5 Gy twice daily for 30 treatments was used. The primary objective was to evaluate the rate of grade ≥3 treatment-related skin, fibrosis, and/or breast pain adverse events (AEs), occurring ≤1 year from re-treatment completion. A rate of ≥13% for these AEs in a cohort of 55 patients was determined to be unacceptable (86% power, 1-sided α = 0.07). RESULTS: Between 2010 and 2013, 65 patients were accrued, and the first 55 eligible and with 1 year follow-up were analyzed. Median age was 68 years. Twenty-two patients had ductal carcinoma in situ, and 33 had invasive disease: 19 ≤1 cm, 13 >1 to ≤2 cm, and 1 >2 cm. All patients were clinically node negative. Systemic therapy was delivered in 51%. All treatment plans underwent quality review for contouring accuracy and dosimetric compliance. All treatment plans scored acceptable for tumor volume contouring and tumor volume dose-volume analysis. Only 4 (7%) scored unacceptable for organs at risk contouring and organs at risk dose-volume analysis. Treatment-related skin, fibrosis, and/or breast pain AEs were recorded as grade 1 in 64% and grade 2 in 7%, with only 1 (<2%) grade ≥3 and identified as grade 3 fibrosis of deep connective tissue. CONCLUSION: Partial-breast reirradiation with 3-dimensional conformal radiation therapy after second lumpectomy for patients experiencing in-breast failures after whole-breast irradiation is safe and feasible, with acceptable treatment quality achieved. Skin, fibrosis, and breast pain toxicity was acceptable, and grade 3 toxicity was rare.

RESUMO

BACKGROUND: Intracystic papillary carcinoma (IPC) of the breast is a rare breast malignancy with an indolent course. However, patients can develop metastatic disease. Indications for surgery and radiotherapeutic management have not been well elucidated. METHODS: We identified 2649 female patients with IPC from the Surveillance, Epidemiology, and End Results (SEER) registry. Differences in demographics, clinical features and survival of patients were assessed using the Kaplan-Meier method and Cox regression. RESULTS: Median age was 67 years. The majority of patients were white with Stage 0 disease. Most patients had lymph node evaluation and only 34% received radiation therapy. Using a log-rank test, survival was significantly better in Caucasian compared to African-American patients, patients with early stage disease, negative lymph nodes and those who received radiation (all p < 0.0001). In a Cox regression survival model adjusting for age, stage and grade, patients who were African-American (hazard ratio [HR] 2.0, CI 1.4-2.8; p < 0.0001) had a significantly higher risk of death than Caucasians. Patients who received radiation therapy (HR 0.5, CI 0.3-0.7; p = 0.0003) had a lower chance of death than patients that did not undergo radiation. CONCLUSION: Overall, IPC has a good prognosis. Survival is improved in Caucasian patients and in patients who receive radiation therapy. Radiation therapy should be offered to women with IPC who undergo breast conserving surgery.

RESUMO

This is a single-arm, pre and post effectiveness study that evaluated the impact of a comprehensive workplace lifestyle program on severe obesity among high cardiovascular disease risk individuals in a large, diverse employee population. Employees of Baptist Health South Florida were considered eligible to participate if they had 2 or more of the following cardiometabolic risk factors: total cholesterol ≥200 mg/dL, systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, hemoglobin A1c ≥6.5%, body mass index ≥30kg/m(2). Participants received a personalized diet plan and physical activity intervention, and were followed for 1 year. Data on anthropometric measurements, blood pressure, blood glucose, and other biochemical measures were collected. Participants' body mass index was calculated and their eligibility for bariatric surgery (BS) also assessed. A total of 297 persons participated in the program; 160 participants completed all procedures through 12 months of follow-up. At baseline, 34% (n = 100) of all participants were eligible for BS. In an intention-to-treat analysis, 27% (n = 27) of BS eligible participants at baseline became ineligible after 12 months. Considering program completers only, 46% of BS eligible participants at baseline became ineligible. Irrespective of BS eligibility at 12 months, mean values of cardiometabolic risk factors among program completers improved after the follow-up period. Workplace wellness programs provide an important option for weight loss that can obviate the need for BS, reduce cardiovascular disease risk, and potentially reduce costs. However, in designing future worksite lifestyle interventions, measures should be taken to improve participation and retention rates in such programs.

RESUMO

OBJECTIVE: This study details 6- and 12-month cardio-metabolic outcomes of an intense 12-week workplace lifestyle intervention program, the My Unlimited Potential (MyUP), conducted in a large healthcare organization. METHODS: This study was conducted among 230 employees of Baptist Health South Florida with high cardiovascular disease (CVD) risk. Employees were considered at high risk and eligible for the study if they had two or more of the following cardio-metabolic risk factors: total cholesterol ≥ 200 mg/dl, systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg, hemoglobin A1C (HbA1c) ≥ 6.5%, body mass index (BMI) ≥ 30 kg/m(2) . RESULTS: At the end of 12 weeks, there was significant reduction in the mean BMI, SBP and DBP, serum lipids, and HbA1c among persons with diabetes. At 1 year, there was significant decline in the mean BMI, SBP and DBP, HbA1c, and high-sensitivity C-reactive protein, and in the prevalence of poor BP control, BMI ≥ 35 kg/m(2) , and abnormal HbA1c among all persons and those with diabetes. CONCLUSIONS: This intensive 12-week lifestyle change program was successful at improving cardio-metabolic risk factors at 1 year. This study provides a template for other workplace programs aimed at improving CVD risk in high-risk employees.

RESUMO

Basal ganglia nongerminomatous germ cell tumors comprise 10% to 15% of germ cell tumor and have substantial morbidity at the time of local failure. In this submitted image we present a case where neoadjuvant chemotherapy unmasked a unilateral caudate head loss consistent with Huntingtonian changes. Careful review of the patient's imaging identified disease within the dorsal striatum that was not previously identified at the time of diagnosis. Review of the diffusion tensor fractional anisotropy imaging identified progressive white matter likely secondary to the occult disease within the dorsal striatum. Although this patient was asymptomatic and had no signs of a movement disorder, similar findings have been noted to be a prelude to such findings several months later. The occult disease was incorporated into the patient's radiotherapy planning target volume as oversight of these changes would have led to a marginal miss and potential early disease relapse.

RESUMO

Approximately 5% of breast cancer patients develop leptomeningeal metastases over the course of their disease. Though several treatments options are available for these patients, their prognosis is typically considered to be poor. We report a case of leptomeningeal failure after a patient underwent prior radiotherapy, radiosurgery, surgery, chemotherapy, and biologic therapy. This patient experienced a prolonged response after receiving bevacizumab and capecitabine. The literature currently contains several reports regarding the use of systemic therapy to manage leptomeningeal metastases from breast cancer, which we summarize. Finally, we review the relevant effects of the patient's treatment modalities and provide a rationale for the mechanism that led to her prolonged response.
