Subharmonic-Aided Pressure Estimation for Monitoring Interstitial Fluid Pressure in Tumors: Calibration and Treatment with Paclitaxel in Breast Cancer Xenografts. ULTRASOUND IN MEDICINE & BIOLOGY 2017; 43:1401-1410. [PMID: 28433436 PMCID: PMC6082419 DOI: 10.1016/j.ultrasmedbio.2017.02.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 01/31/2017] [Accepted: 02/09/2017] [Indexed: 05/07/2023]
Abstract
Interstitial fluid pressure (IFP) in rats with breast cancer xenografts was non-invasively estimated using subharmonic-aided pressure estimation (SHAPE) versus an invasive pressure monitor. Moreover, monitoring of IFP changes after chemotherapy was assessed. Eighty-nine rats (calibration n = 25, treatment n = 64) were injected with 5 × 106 breast cancer cells (MDA-MB-231). Radiofrequency signals were acquired (39 rats successfully imaged) with a Sonix RP scanner (BK Ultrasound, Richmond, BC, Canada) using a linear array (L9-4, transmit/receive: 8/4 MHz) after administration of Definity (Lantheus Medical Imaging, North Billerica, MA, USA; 180 μL/kg) and compared with readings from an invasive pressure monitor (Stryker, Berkshire, UK). An inverse linear relationship was established between tumor IFP and SHAPE (y = -1.06x + 28.27, r = -0.69, p = 0.01) in the calibration group. Use of this relationship in the treatment group resulted in r = 0.74 (p < 0.05) between measured (pressure monitor) and SHAPE-estimated IFP (average error: 6.24 mmHg). No significant before/after differences were observed with respect to paclitaxel treatment (5 mg/kg, Mayne Pharma, Paramus, NJ, USA) with either method (p ≥ 0.15).

Abstract
OBJECTIVE Multigene predictors are being used increasingly in early-stage breast cancer patients for prediction and prognosis. However, one consequence of the increased use of multigene predictors, and the heightened efforts toward their incorporation into routine clinical practice, is the potential for future malpractice litigation. It is, therefore, important to ascertain the strength of the evidence for using the different commercially available multigene predictor assays clinically. We evaluated the literature for evidence of clinical validity of four currently available gene signatures and to assess the influence of the 21-gene-expression assay on changes in treatment recommendations. METHODS A systematic search of the peer-reviewed literature from January 2002 to March 2014 for multigene predictor assays was carried out, and a meta-analysis was conducted. RESULTS The adjusted Cox hazard ratio average for studies that met the eligibility criteria was 3.538 (95% CI: 1.513-8.469). The 21-gene signature showed the highest stability in the estimation of likelihood of distant risk of recurrence. Using the recurrence scores resulted in changes in treatment recommendations in 31.8% of all patients in the studies. CONCLUSION This study may provide insight about the use of multigene predictors in clinical practice for prediction and prognosis of breast cancer.

Abstract
Breast MRI has several roles in the clinical management of breast cancer, including as a screening method for high-risk women, as a diagnostic tool used as an adjunct to mammography and ultrasound, and for the staging of disease extent prior to treatment. In addition to these uses, MRI is also employed to track small changes in tumor size and microenvironment. MRI has produced several early indicators of treatment response in clinical trials over the last 10 years, including initial lesion pattern, changes in lesion size, kinetic parameters, apparent diffusion coefficient and T(2) value; the related technique of (1) H MRS has also shown that choline concentration, T(2) value and water-to-fat ratio are response indicators. In addition to measuring anatomical changes in the lesion size, as performed in traditional radiology, MRI has the ability to track vascular and cellular changes using dynamic contrast-enhanced MRI and diffusion-weighted MRI, respectively. By adding (1) H MRS to MRI examinations, metabolic changes can also be determined. These functional imaging techniques allow studies to focus on early time points relative to neoadjuvant treatment. Early treatment response predictors may allow therapy to be tailored to individual patients and thus aid in the realization of the goal of personalized medicine.

Abstract
PURPOSE This study aims to determine the effect of loss of breast cancer metastasis suppressor 1 (BRMS1) protein expression on disease-free survival in breast cancer patients stratified by estrogen receptor (ER), progesterone receptor (PR), or HER2 status, and to determine whether loss of BRMS1 protein expression correlated with genomic copy number changes. EXPERIMENTAL DESIGN A tissue microarray immunohistochemical analysis was done on tumors of 238 newly diagnosed breast cancer patients who underwent surgery at the Cleveland Clinic between January 1, 1995 and December 31, 1996, and a comparison was made with 5-year clinical follow-up data. Genomic copy number changes were determined by array-based comparative genomic hybridization in 47 breast cancer cases from this population and compared with BRMS1 staining. RESULTS BRMS1 protein expression was lost in nearly 25% of cases. Patients with tumors that were PR negative (P=0.006) or HER2 positive (P=0.039) and <50 years old at diagnosis (P=0.02) were more likely to be BRMS1 negative. No overall correlation between BRMS1 staining and disease-free survival was observed. A significant correlation, however, was seen between loss of BRMS1 protein expression and reduced disease-free survival when stratified by either loss of ER (P=0.008) or PR (P=0.029) or HER2 overexpression (P=0.026). Overall, there was poor correlation between BRMS1 protein staining and copy number status. CONCLUSIONS These data suggest a mechanistic relationship between BRMS1 expression, hormone receptor status, and HER2 growth factor. BRMS1 staining could potentially be used in patient stratification in conjunction with other prognostic markers. Further, mechanisms other than genomic deletion account for loss of BRMS1 gene expression in breast tumors.

Abstract
Diagnostic assays for HER2 in breast cancer provide important prognostic information and independently help guide management by identifying patients who are the most likely to benefit from Herceptin-targeted therapy. The biological events underlying HER2 -driven breast cancer that can be assessed in routine clinical specimens include the evaluation of gene amplification by fluorescence in situ hybridization (FISH), enhanced messenger RNA expression by real-time polymerase chain reaction, and the assessment of protein overexpression at the tumor cell membrane by immunohistochemistry (IHC). Immunohistochemistry and FISH methodologies have the advantage of being morphologically driven, allowing for correlations between HER2 expression and morphologic features. However, each has important advantages and disadvantages, which are discussed in detail. Although immunohistochemistry is familiar and readily accommodated in most surgical pathology laboratories, increasing demands for FISH testing in the clinical setting will require greater familiarity with the technical aspects of FISH assays and their interpretation by the greater laboratory community. In this review, we provide an overview of FISH testing for HER2 in breast cancer, with an emphasis on technical considerations, interpretive guidelines, scoring criteria, and quality control. The development of automated platforms for hybridization, image analysis for signal enumeration, and experience with FISH interpretation should broaden the availability of this technology for clinical diagnostic testing.

Abstract
PURPOSE In order to improve the breast conservation rate for noninflammatory operable breast cancer stage II and IIIa, neoadjuvant chemotherapy containing vinorelbine, 25 mg/m(2), epirubicin, 35 mg/m(2), and methotrexate, 20 mg/m(2), VEM, was administered days 1 and 8 every 28 days for six cycles. METHODS From October, 1991 to April, 1996, 89 patients (median age 52 years, range 31-72; 68 stage II and 19 stage IIIa) received 519 cycles (median six) of VEM chemotherapy. RESULTS Hematotoxicity was mild (World Health Organization grade 3-4 neutropenia in 28% of cycles for 22 patients, and anemia or thrombocytopenia >grade 2) when it occurred, and there were no toxic deaths. The clinical objective response was 90% (28% complete response and 62% partial response). All patients underwent surgery: 77 (87%) had conservative and 12 (13%) had modified radical mastectomy, and 12 (14%) reached pathological complete response. At December, 2000, with a median follow-up of 86 months (39-100), 13 patients had relapsed, and five had died of metastatic disease. Median disease-free survival was 100 months (8.4 years) and median survival had not yet been reached.

Abstract
Surgical resection of a primary tumour is often not sufficient to cure a patient. Even when no residual cancer can be detected at time of surgery, metastases may appear in the following years, which indicates that the primary tumour had apparently spread before surgery. Following surgery, systemic chemotherapy may be used to eradicate micro-metastatic disease. Here we present two unconventional strategies that implement new insights into tumour biology and tumour immunology in the treatment of patients with cancer. Both experimental strategies use the individual characteristics of the patient's primary tumour to optimise the control of life-threatening micro-metastases. We aim to modulate the patient's adaptive immune system, targeting it towards the patient's own tumour cells to eradicate residual disease following local treatment. In one approach, this is done by autologous tumour cell vaccinations as adjuvant treatment for colon cancer patients and, in a second approach, by giving chemo-immunotherapy before local treatment to women with locally advanced breast cancer.

Abstract
The biological characteristics of the tumor are used to estimate prognosis and select appropriate systemic therapy for patients with early-stage breast cancer. Well-established molecular prognostic factors include the estrogen and progesterone receptors, proliferation markers, and the HER2 gene. Novel tumor markers with potential clinical utility include molecules involved in cell transformation, invasion, and metastases. We review the available data supporting the utility of established prognostic and predictive molecular factors, and discuss challenges for integrating novel molecular markers into clinical practice.

Abstract
PURPOSE To determine whether [(18)F]-fluorodeoxy-D-glucose ([(18)F]-FDG) positron emission tomography (PET) can predict the pathologic response of primary and metastatic breast cancer to chemotherapy. PATIENTS AND METHODS Thirty patients with noninflammatory, large (> 3 cm), or locally advanced breast cancers received eight doses of primary chemotherapy. Dynamic PET imaging was performed immediately before the first, second, and fifth doses and after the last dose of treatment. Primary tumors and involved axillary lymph nodes were identified, and the [(18)F]-FDG uptake values were calculated (expressed as semiquantitative dose uptake ratio [DUR] and influx constant [K]). Pathologic response was determined after chemotherapy by evaluation of surgical resection specimens. RESULTS Thirty-one primary breast lesions were identified. The mean pretreatment DUR values of the eight lesions that achieved a complete microscopic pathologic response were significantly (P =.037) higher than those from less responsive lesions. The mean reduction in DUR after the first pulse of chemotherapy was significantly greater in lesions that achieved a partial (P =.013), complete macroscopic (P =.003), or complete microscopic (P =.001) pathologic response. PET after a single pulse of chemotherapy was able to predict complete pathologic response with a sensitivity of 90% and a specificity of 74%. Eleven patients had pathologic evidence of lymph node metastases. Mean pretreatment DUR values in the metastatic lesions that responded did not differ significantly from those that failed to respond (P =.076). However, mean pretreatment K values were significantly higher in ultimately responsive cancers (P =.037). The mean change in DUR and K after the first pulse of chemotherapy was significantly greater in responding lesions (DUR, P =.038; K, P =.012). CONCLUSION [(18)F]-FDG PET imaging of primary and metastatic breast cancer after a single pulse of chemotherapy may be of value in the prediction of pathologic treatment response.

Abstract
Multiple metachronous primary malignancies are becoming increasingly frequent; however, multiple synchronous primary malignancies are still unusual. We report the case of a 61-year-old woman with synchronous stage IIIB ductal carcinoma of the left breast and FIGO stage IB2 squamous cell carcinoma of the cervix. The patient was treated initially every 4 weeks with a 24-h intravenous infusion of paclitaxel (175 mg/m2) followed by a 1-h infusion of carboplatin (area under the curve of 5 mg/ml x min) with concurrent irradiation of the pelvis. Significant toxic reactions including nausea, vomiting, and diarrhea required hospitalization or outpatient intravenous fluids and antiemetics. After four cycles of chemotherapy, the breast cancer was in complete clinical remission, and the patient underwent a modified radical mastectomy with axillary lymph node dissection. Pathologic findings revealed a few microscopic foci of residual infiltrating ductal carcinoma exhibiting a marked treatment effect; none of the 14 axillary lymph nodes removed showed evidence of metastatic tumor. A near-complete pathologic response of the breast cancer and a complete clinical response of the cervical cancer were obtained. Adjuvant chemotherapy for the breast cancer was then initiated, followed by radiation and hormonal therapy.
