Non-BRCA DNA Damage Repair Gene Alterations and Response to the PARP Inhibitor Rucaparib in Metastatic Castration-Resistant Prostate Cancer: Analysis From the Phase II TRITON2 Study.

Purpose: Genomic alterations in DNA damage repair (DDR) genes other than may confer synthetic lethality with PARP inhibition in metastatic castration-resistant prostate cancer (mCRPC). To test this hypothesis, the phase II TRITON2 study of rucaparib included patients with mCRPC and deleterious non- DDR gene alterations.

Patients And Methods: TRITON2 enrolled patients who had progressed on one or two lines of next-generation androgen receptor-directed therapy and one taxane-based chemotherapy for mCRPC.

: Evaluation of AHCC Supplementation to Modulate the Host Immunity to Clear High-Risk Human Papillomavirus Infections.

There is currently no effective medicine or supplement for clearance of high risk- human papillomavirus (HR-HPV) infections. We have taken a systematic approach evaluating the potential use of AHCC supplementation to support clearance of HR-HPV infections. The primary objective of this research was to evaluate AHCC supplementation to modulation of the host immune system to clear HR-HPV infections from bench to bedside.

Identifying the need to refine the potential patient risk factors for niraparib-induced thrombocytopenia.

Objective: Niraparib is a poly (ADP-ribose) polymerase inhibitor (PARP) approved for use in maintenance therapy for ovarian cancer that is associated with the unpredictable grade 3/4 thrombocytopenia. This study was conducted to refine patient dosing recommendations for niraparib based upon clinical practice observations of grade 3/4 thrombocytopenia.

Methods And Materials: Six patient cases were reviewed to identify similarities in patient factors.

Quality Improvement to Demonstrate the Lack of Reliability of the Human Papillomavirus mRNA Assay to Identify Women With Latent Human Papillomavirus Infections.

Objective: To assess the consistency between human papillomavirus (HPV) mRNA testing in women with a history of previous HPV infections diagnosed by HPV DNA assay and the potential effects on follow-up HPV screening.

Methods: This was a quality improvement study that used data from a pathology laboratory software database reviewed from November 2014 to June 2016 to identify female patients aged 30 years or older with greater than one HPV-positive result, including one or more HPV mRNA assay results and one or more documented HPV DNA assay results for comparison. Previous correlative cytology and colposcopic histopathology were also documented.

A retrospective evaluation of activity of gemcitabine/platinum regimens in the treatment of recurrent ovarian cancer.

Background: While many of these agents have been compared in prospective clinical trials, the gemcitabine/platinumbased regimens have not been compared in a prospective, randomized clinical trial. While bothgemcitabine/carboplatin and gemcitabine/cisplatin have a similar ORR in separate clinical trials, the tworegimens have never been directly been compared. With overlapping dose-limiting toxicity of thrombocytopenia, the gemcitabine/carboplatin regimen has been challenging to employ in the clinical setting in previously treated ovarian cancer patients and is often associated with treatment delays and/or dose reductions.

Objective: To determine the activity of fucoidan from Undaria pinnatifida (UPF) and Fucus vesiculosus (FVF) when given in combination of chemotherapy drugs using selected human breast or ovarian cancer orthotopic mouse models.

Methods: Mice were inoculated with 1 × 10 cells of TOV-112d, MCF-7, or ZR-75 subcutaneously or SKOV-GFP-Luc intraperitoneally on day 0. MCF-7 and ZR-75 mice were administered with estradiol valerate 2 mg/kg in 0.

Preclinical Evaluation of Safety of Fucoidan Extracts From Undaria pinnatifida and Fucus vesiculosus for Use in Cancer Treatment.

Objectives: To evaluate potential hepatic metabolism-mediated drug interactions with fucoidan from Undaria pinnatifida (UPF) or Fucus vesiculosus (FVF) and potential growth inhibition activity with either fucoidan alone or with chemotherapy. In vivo studies were done to confirm safety and investigate fucoidan-mediated immune modulation.

Methods: Cytochrome P450 (CYP450) 3A4, 2C8, 2C9, and 2D6 inhibition experiments were conducted in vitro followed by an ex vivo human hepatocytes model to evaluate the CYP450 induction potential of each fucoidan at highest theoretical concentrations.

Do some epithelial ovarian cancers originate from a fallopian tube ciliate cell lineage?

There is a general agreement that a large subpopulation of serous ovarian cancers arise from the fallopian tube mucosal epithelium. However, there is still some debate as to whether the cancers originate from a secretory or ciliate cell lineage. One well established method for determining the origin of a cell line is to document the expression of genes and proteins that are cell type specific.

Methods: The study consisted of 7 treatment arms (n=10) conducted in 2 breast cancer mouse models: MCF-7 and ZR-75. Treatment groups included untreated, vehicle, AHCC 50 mg/kg, AHCC 50 mg/kg + tamoxifen 10 mg/kg, tamoxifen 10 mg/kg, AHCC 50 mg/kg + letrozole 10 µg/mouse, or letrozole 10 µg/mouse.

Pharmacists' roles in oncology pharmacy services: Results of a global survey.

Background Oncology pharmacists are capable of providing medication therapy management (MTM) because of their level of training, practice experiences, and responsibilities. Very little data exist about their current practice, including changing roles in the multidisciplinary team, overall impact, and effects in the education of patients and healthcare professionals. Methods A 70-item survey about oncology pharmacists' activities in oral chemotherapy programs, MTM, and collaborative practice agreements (CPAs) was deployed using a web survey tool (Qualtrics, Provo, UT, USA), targeting pharmacist members of American College of Clinical Pharmacy (ACCP) Hematology/Oncology Practice and Research Network (PRN).

Defining the impact of the use of granulocyte colony stimulating factors on the incidence of chemotherapy-induced neutropenia in patients with gynecologic malignancies.

Purpose The objectives of this study were to characterize the incidence of chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN) with specific chemotherapy agents commonly used in the treatment of gynecologic malignancies, as well as defining the impact of granulocyte colony stimulating factors (G-CSF) on the prevention of CIN and FN in this patient population. Methods This retrospective analysis was conducted from a database of 635 gynecologic cancer patients who received chemotherapy between 1 September 2007 and 31 August 2008. A logistic regression analysis was conducted to determine the impact of potential covariates on the overall incidence of CIN.

TroVax in colorectal cancer.

Currently, the backbone of therapy for metastatic disease is cytotoxic chemotherapy, along with the recent addition of targeted therapy based on molecular markers with KRAS testing. Despite the improvement in survival for metastatic colon cancer, newer agents are still needed. The clinical activity of TroVax in metastatic colon cancer has been studied in a small number of clinical trials.

CDKL2 promotes epithelial-mesenchymal transition and breast cancer progression.

The epithelial-mesenchymal transition (EMT) confers mesenchymal properties on epithelial cells and has been closely associated with the acquisition of aggressive traits by epithelial cancer cells. To identify novel regulators of EMT, we carried out cDNA screens that covered 500 human kinases. Subsequent characterization of candidate kinases led us to uncover cyclin-dependent kinase-like 2 (CDKL2) as a novel potent promoter for EMT and breast cancer progression.

Clinical outcomes model in renal cell cancer patients treated with modified vaccinia Ankara plus tumor-associated antigen 5T4.

Aims: We developed an outcomes model to select patients for renal cell cancer vaccine immunotherapy.

Materials And Methods: We examined clinical data from 2 phase II studies of modified vaccinia Ankara as vector to express 5T4 (MVA-5T4), calculated progression-free survival (PFS) and overall survival (OS), and created risk groups based on the number of factors involved.

Results: Median OS was 12.

Folate receptor-β constitutes a marker for human proinflammatory monocytes.

Activated macrophages are commonly involved in the pathogenesis of inflammatory and autoimmune diseases and have been frequently reported to overexpress FR-β. Although FR-targeted therapies aimed at eliminating activated macrophages have shown promise for treating inflammatory diseases, little work has been performed to evaluate whether other hematopoietic cells might also express FR-β. Analysis of peripheral blood cells with a mAb to human FR-β reveals that only monocytes express FR-β.

A Phase I/Ib study of folate immune (EC90 vaccine administered with GPI-0100 adjuvant followed by EC17) with interferon-α and interleukin-2 in patients with renal cell carcinoma.

Folate immune (EC90 vaccine with GPI-0100 adjuvant followed by EC17) is a novel folate-targeted hapten immunotherapy designed to exploit the overexpression of folate receptors on renal cell carcinoma (RCC) cells. In this open-label, phase I/II clinical study, we report the safety, pharmacokinetics, and antitumor activity of folate immune with concurrent interleukin-2 (IL-2) and interferon-α (IFN-α) in patients with recurrent or metastatic RCC. Twenty-four patients were enrolled.

Fixed, low-dose rasburicase for the treatment or prevention of hyperuricemia in adult oncology patients.

Purpose: Rasburicase is a recombinant urate oxidase enzyme administered to high risk patients or to those with preexisting hyperuricemia from tumor lysis syndrome (TLS). The objective of this retrospective review is to evaluate and characterize the use of fixed, low-dose rasburicase for the treatment of hyperuricemia in adult patients.

Patients/methods: A retrospective chart review from 1 October 2005 to 31 December 2011 was conducted in adult oncology patients who received fixed, low-dose rasburicase.

Clinical prognostic factors associated with outcome in patients with renal cell cancer with prior tyrosine kinase inhibitors or immunotherapy treated with everolimus.

Background: The mTOR inhibitor, everolimus, is approved for the treatment of metastatic renal cell carcinoma (RCC). However, prognostic models are needed to determine the patients who would most benefit from this therapy. We have developed a model based on clinical parameters and patient stratification into risk groups to predict patients with RCC who will derive the most benefit from treatment with everolimus.

Identification of Pre- and Post-Treatment Markers, Clinical, and Laboratory Parameters Associated with Outcome in Renal Cancer Patients Treated with MVA-5T4.

The recent approvals of immunotherapeutic agents (Sipuleucel-T and Ipilimumab) for the treatment of different solid tumors gave a boost to the growing cancer immunotherapy field, even though few immunotherapy studies have demonstrated convincingly that there is a direct link between the predicted mode of action of an immunological compound and therapeutic benefit. MVA-5T4 (TroVax(®)) is a novel vaccine combining the tumor-associated antigen 5T4 to an engineered vector-modified vaccinia Ankara (MVA). MVA helps to express the oncofetal 5T4 antigen and subsequently trigger a tumor-directed immune reaction.

A phase II trial of androgen deprivation therapy (ADT) plus chemotherapy as initial treatment for local failures or advanced prostate cancer.

Purpose: Long-term hormonal ablation in prostate cancer is associated with decreased overall health and quality of life. Few reports emphasized the role of chemotherapy in the management of early stage prostate cancer. This study analyzed the safety and efficacy of androgen deprivation therapy (ADT) plus chemotherapy as initial treatment for patients identified as local failures or not eligible for prostatectomy or radiation therapy due to advanced disease presentation.

A phase I study of folate immune therapy (EC90 vaccine administered with GPI-0100 adjuvant followed by EC17) in patients with renal cell carcinoma.

This is the first phase I, open-label study to assess the safety, pharmacokinetics, and antitumor activity of a novel immunotherapeutic regimen known as Folate Immune (EC90 vaccine administered with GPI-0100 adjuvant followed by EC17, a folate-targeted hapten immunotherapy that targets folate receptor expressing cancer cells), which is designed to convert poorly immunogenic tumors to highly immunogenic tumors in patients with metastatic renal cell carcinoma. Three to 6 patients were enrolled in each cohort. In the vaccination phase, patients were given once weekly vaccinations of 0.

Sinonasal undifferentiated carcinoma (SNUC): morphoproteomic-guided treatment paradigm with clinical efficacy.

Sinonasal undifferentiated carcinoma (SNUC) is a rare and highly malignant tumor that occurs in the nasal cavity and/or paranasal sinuses. Prognosis is poor despite multimodality treatment. Currently, there is no optimal standard of treatment, partially due to a lack of research defining the biology of such tumors.

Safety and preliminary efficacy analysis of the mTOR inhibitor ridaforolimus in patients with taxane-treated, castration-resistant prostate cancer.

Background: Few options are available after taxane-based therapy in men with CRPC. Genetic alterations involving the mTOR pathway have been associated with CRPC development, raising the hypothesis that blocking mTOR signaling may be an effective targeted approach to treatment.

Patients And Methods: In this open-label phase II study, the mTOR inhibitor Ridaforolimus was administered at a dose of 50 mg intravenous once weekly to 38 patients with taxane-treated CRPC.
