Two staged phase II clinical trial of Eribulin monotherapy in advanced or recurrent cervical cancer.

Background: Eribulin a microtubule targeting agent and analog of Halichondrin B, a natural product isolated from marine sponge H. okadai, has proven clinical efficacy in metastatic pretreated breast cancer and liposarcoma. We conducted a 2-stage Phase II study of eribulin in patients with advanced/recurrent cervical cancer to examine its clinical activity and evaluate biomarkers for predictors of response.

Phase II study of the histone deacetylase inhibitor vorinostat (Suberoylanilide Hydroxamic Acid; SAHA) in recurrent or metastatic transitional cell carcinoma of the urothelium - an NCI-CTEP sponsored: California Cancer Consortium trial, NCI 6879.

Background: Until the advent of T cell check point inhibitors standard second-line therapy for patients with metastatic urothelial cancer (mUC) was undefined. Histone deacetylase inhibitors (HDACi) have anti-cancer activity in a variety of tumor models including modulation of apoptosis in bladder cancer cell lines. We evaluated the efficacy and toxicity of the HDACi vorinostat in patients with mUC failing first-line platinum-based therapy either in the adjuvant/neoadjuvant setting or for recurrent/advanced disease.

Purpose: Patients with metastatic urothelial carcinoma are often ineligible for cisplatin-based treatments. A National Cancer Institute Cancer Therapy Evaluation Program-sponsored trial assessed the tolerability and efficacy of a gemcitabine-eribulin combination in this population.

Methods: Patients with treatment-naïve advanced or recurrent metastatic urothelial carcinoma of the bladder, ureter, or urethra not amenable to curative surgery and not candidates for cisplatin-based therapy were eligible.

Pancreaticoduodenectomy in the surgical management of primary retroperitoneal sarcoma.

Background: In retroperitoneal sarcoma (RPS), the optimal extent of resection must balance adequate disease control with potential for morbidity. We sought to study the frequency and outcomes after a Whipple procedure or pancreaticoduodenectomy (PD) in patients undergoing resection for primary RPS.

Methods: Participating referral centers within the Trans-Atlantic Retroperitoneal Sarcoma Working Group provided retrospective data from January 2007 to December 2016 for patients with primary RPS who underwent PD along with the total number of consecutive resections done during the same time period.

HER2 Gene Amplification Testing by Fluorescent In Situ Hybridization (FISH): Comparison of the ASCO-College of American Pathologists Guidelines With FISH Scores Used for Enrollment in Breast Cancer International Research Group Clinical Trials.

Purpose ASCO and the College of American Pathologists (ASCO-CAP) recently recommended further changes to the evaluation of human epidermal growth factor receptor 2 gene (HER2) amplification by fluorescent in situ hybridization (FISH). We retrospectively assessed the impact of these new guidelines by using annotated Breast Cancer International Research Group (BCIRG) -005, BCIRG-006, and BCIRG-007 clinical trials data for which we have detailed outcomes. Patients and Methods The HER2 FISH status of BCIRG-005/006/007 patients with breast cancers was re-evaluated according to current ASCO-CAP guidelines, which designates five different groups according to HER2 FISH ratio and average HER2 gene copy number per tumor cell: group 1 (in situ hybridization [ISH]-positive): HER2-to-chromosome 17 centromere ratio ≥ 2.

Phase I, dose-escalation study of the targeted cytotoxic LHRH analog AEZS-108 in patients with castration- and taxane-resistant prostate cancer.

Purpose: AEZS-108, formerly AN-152, is a cytotoxic hybrid molecule consisting of a luteinizing hormone-releasing hormone (LHRH) agonist moiety covalently coupled to doxorubicin, allowing it to deliver doxorubicin selectively to cells expressing LHRH receptors. LHRH receptors are expressed on the cell membrane of many tumors, including prostate cancer. This phase I study determined the maximum tolerated dose (MTD) of AEZS-108 in men with taxane- and castration-resistant prostate cancer (CRPC) while providing additional information on the safety profile and efficacy of this agent.

Efficacy of oxaliplatin plus pemetrexed in chemotherapy pretreated metastatic castration-resistant prostate cancer.

Background: Although new androgen-targeted therapies offer prolonged survival in metastatic castration-resistant prostate cancer (CRPC), most men still face progressive disease and require additional therapy. Oxaliplatin and pemetrexed have each shown modest activity in the treatment of CRPC. Given their favorable nonoverlapping toxicity profiles, we studied them in combination.

Combination of molecular alterations and smoking intensity predicts bladder cancer outcome: a report from the Los Angeles Cancer Surveillance Program.

Background: Traditional single-marker and multimarker molecular profiling approaches in bladder cancer do not account for major risk factors and their influence on clinical outcome. This study examined the prognostic value of molecular alterations across all disease stages after accounting for clinicopathological factors and smoking, the most common risk factor for bladder cancer in the developed world, in a population-based cohort.

Methods: Primary bladder tumors from 212 cancer registry patients (median follow-up, 13.

Conditional survival of high-grade glioma in Los Angeles County during the year 1990-2000.

Survival probabilities for high-grade glioma are estimated at the time of diagnosis and provide limited information following treatment. This study determined dynamic indices to predict post-diagnosis survival for high-grade glioma patients. Survival information for 2,743 patients with high-grade glioma, diagnosed in Los Angeles County during the years 1990-2000, were used to estimate conditional survival probabilities with 95 % confidence intervals, for patients still alive at 1, 2, 3, 4, or 5 years after diagnosis.

A phase II study of halichondrin B analog eribulin mesylate (E7389) in patients with advanced non-small cell lung cancer previously treated with a taxane: a California cancer consortium trial.

Introduction: Eribulin mesylate (E7389) is an analog of halichondrin B with a unique mechanism of microtubule binding. The activity and toxicity of eribulin were assessed in patients with advanced non-small cell lung cancer (NSCLC) previously treated with a taxane.

Methods: An open-label phase II study included patients with NSCLC previously treated with platinum and taxane-based therapy, with up to two prior cytotoxic regimens, given for metastatic disease or as adjuvant therapy.

Phase I clinical trial of pegylated liposomal Doxorubicin and docetaxel in patients with advanced solid tumors.

Objective: The primary objective of this study was to determine the maximum tolerated dose (MTD) of pegylated liposomal doxorubicin (PLD) and docetaxel (T) administered in 4 week cycles in patients with advanced solid tumors.

Patients And Methods: Patients were treated with intravenous PLD on day 1 and T on days 1, 8, and 15. Once the MTD was reached the schedule of PLD was changed to days 1 and 15 to explore an alternative and potentially more manageable dosing schedule.

Oral fenretinide in biochemically recurrent prostate cancer: a California cancer consortium phase II trial.

Background: Fenretinide is a synthetic retinoid that is cytotoxic to a variety of cancers. We conducted a phase II trial of oral fenretinide in patients with biochemically recurrent prostate cancer.

Patients And Methods: Eligible patients had histologically confirmed prostate cancer and a confirmed rising prostate-specific antigen (PSA) >or= 2 ng/mL following either radical prostatectomy and/or pelvic radiation therapy, without clinical or radiographic evidence of metastasis.

RUNX3 methylation reveals that bladder tumors are older in patients with a history of smoking.

Exposure to tobacco smoke is associated with increased DNA methylation at certain genes in both lung and bladder tumors. We sought to identify interactions in bladder cancer between DNA methylation and a history of smoking, along with any possible effect of aging. We measured DNA methylation in 342 transitional cell carcinoma tumors at BCL2, PTGS2 (COX2), DAPK, CDH1 (ECAD), EDNRB, RASSF1A, RUNX3, TERT, and TIMP3.

Overexpression of E-cadherin protein in metastatic breast cancer cells in bone.

Aim: The aim of the present study was to evaluate E-cadherin, whose expression remains poorly understood in the intercellular adhesion of metastatic breast cancer cells in bone, the most prevalent site for metastatic growth.

Materials And Methods: An immunohistochemical staining method was used for the localization of E-cadherin protein in tissue biopsy specimens of normal breast (n = 9) and well- (n = 8), moderately (n = 8) or poorly (n = 14) differentiated invasive primary breast cancer and metastatic breast cancer in bone (n = 17). The expression patterns of E-cadherin were classified as homogeneous (most cells exhibiting positivity), heterogeneous (a few scattered patches of cells with positivity) or negative (cells with undetectable positivity).

Phase II clinical trial of bevacizumab and low-dose metronomic oral cyclophosphamide in recurrent ovarian cancer: a trial of the California, Chicago, and Princess Margaret Hospital phase II consortia.

Purpose: Vascular endothelial growth factor (VEGF) plays an important role in the biology of ovarian cancer (OC). Inhibitors of VEGF suppress tumor growth in OC models. Metronomic chemotherapy, defined as frequent administration of low doses of cytotoxic chemotherapy, suppresses tumor growth, possibly by inhibiting angiogenesis.

Telomerase and markers of cellular proliferation are associated with the progression of cervical intraepithelial neoplasia lesions.

The expression of the catalytic subunit of telomerase protein (human telomerase reverse transcriptase [hTERT]), which is associated with telomerase activity, was evaluated as a potential marker of the high-grade premalignant cervical intraepithelial neoplasia (CIN 2/3) lesions. For comparison, cases of normal cervical squamous mucosa, low-grade CIN1 lesion, and cervical squamous cell carcinoma were included. The hTERT expression was also compared with Ki-67 and topoisomerase II-alpha (TPII-alpha) to determine the proliferative activity of the hTERT-positive dysplastic cells by a quantitative immunohistochemical staining method and was classified as follows: negative, 5% or less; moderate, 6% to 50%; or high, greater than 50% of the positive cells.

Salvage chemotherapy with CPT-11 for recurrent meningioma.

Background: A prospective Phase II study of irinotecan (CPT-11) in adult patients with recurrent surgery and radiotherapy-refractory WHO Grade I meningioma.

Methods: Sixteen patients (5 men; 11 women) ages 48-70 years (median 62.5), with recurrent meningioma were treated.

Phase II trial of intracerebrospinal fluid etoposide in the treatment of neoplastic meningitis.

Background: The purpose of the current study was to determine the toxicity and response of a fixed dose intracerebrospinal fluid (CSF) etoposide in the treatment of patients with newly diagnosed neoplastic meningitis (NM). NM reportedly occurs in 1% to 5% of patients with known cancer. Currently available treatment options are limited and provide only modest benefit.

Early ductal decompression versus conservative management for gallstone pancreatitis with ampullary obstruction: a prospective randomized clinical trial.

Objective: To compare the efficacy of endoscopic retrograde cholangiopancreatography +/- endoscopic sphincterotomy (ERCP +/- ES) versus traditional conservative management in early gallstone pancreatitis with persistent ampullary obstruction (GSP + AO).

Summary Background Data: The effectiveness of early ERCP +/- ES in this setting is controversial.

Methods: Sixty-one consecutive patients with GSP + AO within 48 hours from the onset of symptoms were randomized to receive either conservative treatment and selective ERCP +/- ES after 48 hours (control group, 31 patients) or initial conservative treatment and systematic ERCP +/- ES within 48 hours if obstruction persisted 24 hours or longer (study group, 30 patients).

Salvage chemotherapy with cyclophosphamide for recurrent temozolomide-refractory anaplastic astrocytoma.

Background: A prospective Phase II study of cyclophosphamide (CYC) was conducted in adult patients with recurrent temozolomide-refractory anaplastic astrocytoma (AA) with a primary objective of evaluating 6-month progression-free survival (PFS).

Methods: Forty patients (28 men, 12 women) ages 26-57 years (median, 43 yrs) with neuroradiographically recurrent AA were treated. All patients had previously been treated with surgery and involved-field radiotherapy.

Gene polymorphisms of epidermal growth factor receptor and its downstream effector, interleukin-8, predict oxaliplatin efficacy in patients with advanced colorectal cancer.

Background: Researchers have recently reported an association between the epidermal growth factor receptor (EGFR) pathway and platinum-chemotherapy sensitivity in cancer patients. The (CA)(n) repeat polymorphism in intron 1 of the EGFR gene has been identified and found to alter EGFR expression in vitro as well as in vivo. A higher number of these CA repeats is associated with lower EGFR levels, whereas a low number of repeats is associated with higher EGFR levels.

Association between monocyte Fcgamma subclass expression and acute coronary syndrome.

BACKGROUND: Atherosclerosis lesions contain abundant immunoglobulins complexed with oxidized LDL (OxLDL) that are endocytosed by macrophages to form foam cells. While recent evidence supports a role for the macrophage scavenger receptor pathway in 75-90% of OxLDL uptake, in vitro evidence suggests another potential uptake pathway could involve autoantibody binding to IgG subclass-specific Fc receptors. OBJECTIVE AND METHODS: To address this mechanism from an in vivo standpoint, the objective of this study was to utilize flow cytometry to prospectively determine monocyte Fcgamma (FcR) I, II, and III receptor expression levels in patients with acute coronary syndrome (ACS, n = 48), diabetes mellitus (DM, n = 59), or neither (C, n = 88).

LEA-135 expression: its association with a lower risk of recurrence and increased overall survival of patients with lymph node-positive primary invasive breast cancer.

A retrospective study was undertaken to determine and compare the prognostic significance of LEA-135 protein expression by immunohistochemistry with other prognostic pathological parameters, with respect to recurrence and overall survival. This study was conducted in freshly-frozen tissue sections from a cohort of 367 patients having primary invasive breast cancer, with axillary lymph node metastasis. The association of LEA-135 expression was compared with estrogen and progesterone receptor status, segmentectomy or radical mastectomy and hormonal therapy or chemotherapy in terms of recurrence or disease-free survival.

Temozolomide for treatment-resistant recurrent meningioma.

A prospective Phase II study of temozolomide (TMZ) was conducted in 16 patients with refractory meningioma. All patients had previously been treated with surgery and involved-field radiotherapy; however, no patient had prior chemotherapy. TMZ was administered orally for 42 consecutive days every 10 weeks.
