OBJECTIVE: We examined whether epidermal growth factor receptor (EGFR) expression in circulating tumor cells (CTCs) can be used to predict survival in a population of bone-metastatic castration-resistant prostate cancer (mCRPC) patients treated with docetaxel chemotherapy. METHODS: All patients with mCRPC who had experienced treatment failure with androgen-deprivation therapy and had received docetaxel chemotherapy were eligible. CTCs and EGFR expression in CTCs were enumerated with the CellSearch System in whole blood...

Combination of polymer therapeutics and hyperthermia has been shown to enhance accumulation in selectively heated tumor tissue. The additional use of heat shock (HS)-targeting towards tumor tissues can further enhance accumulation and retention, and improve therapeutic outcomes. In this work, high intensity focused ultrasound (HIFU) was used to generate hyperthermia in prostate tumor tissue. Upregulation of the cell surface HS receptor glucose regulated protein 78 kDa (GRP78) was observed after treatment with HIFU hyperthermia which was then targeted by specific HS-targeting peptides...

BACKGROUND: Neoadjuvant chemotherapy for resectable advanced esophageal squamous cell carcinoma (ESCC) requires reassessment. We have conducted a trial aiming at the comparison between DCF and ACF concerning perioperative adverse events. METHODS: Patients were randomly assigned to receive either DCF [docetaxel 70 mg/m2, cisplatin 70 mg/m2 on day 1, and 5-fluorouracil (5-FU) 700 mg/m2 for 5 days] every 3 weeks or ACF (adriamycin 35 mg/m2, cisplatin 70 mg/m2 on day 1, and 5-FU 700 mg/m2 for 7 days) every 4 weeks...

More than 800 oesophageal tumours are diagnosed each year in Hungary. The disease is characterized by high mortality. The curative treatment traditionally surgical, although the study results of recent decades pointed out that patient outcome can be improved with the proper application of radio- and chemotherapy. The diverse study designs, the low number of recruited patients and the sometimes conflicting results make the determination of optimal treatment difficult. The aim of this work is to facilitate the choice of treatment modality with the best outcome, especially with the view of medical oncologists...

BACKGROUND: Neoadjuvant therapy response correlates with survival in multiple gastrointestinal malignancies. To potentially augment neoadjuvant response for pancreas adenocarcinoma, we intensified treatment with stereotactic body radiotherapy (SBRT) following multi-agent chemotherapy. Using this regimen, we analyzed whether the College of American Pathology (CAP) tumor regression grade (TRG) at pancreatectomy correlated with established response biomarkers and survival. MATERIALS AND METHODS: We identified borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer patients treated according to our institutional clinical pathway who underwent surgical resection with reported TRG (n = 81, median follow-up after surgery 24...

BACKGROUND: Elderly breast cancer patients are affected by poorer quality of life (QoL) compared to younger patients. Because QoL has a relevant impact on guideline-adherent treatment, elderly breast cancer patients are often undertreated, especially with regard to adjuvant chemotherapy, and overall survival is decreased. Thus, understanding the impact of chemotherapy on QoL in elderly patients is crucial. This study compared QoL in patients aged < 65 years and 65 to 70 years receiving adjuvant chemotherapy as a secondary outcome in the prospective randomized multicenter ADEBAR trial...

The present work is aimed at evaluating the antitumour properties of a Pd(II) dinuclear complex with the biogenic polyamine spermine, by investigating: i) the anti-angiogenic and anti-migration properties of a Pd(II) dinuclear complex with spermine (Pd2Spm); ii) the anti-proliferative activity of Pd2Spm against a triple negative human breast carcinoma (MDA-MB-231); and finally iii) the putative interaction mediated by combination of Pd2Spm with Docetaxel. Anti-invasive (anti-angiogenic and anti-migratory) as well as anti-proliferative capacities were assessed, for different combination schemes and drug exposure times, using the CAM assay and VEGFR2 activity measurement, the MatrigelTM method and the SRB proliferation test...

STUDY OBJECTIVE: Gastric cancer is the fifth most common malignancy and second leading cause of cancer-related mortality. Chemotherapy options for patients who fail first-line treatment are limited. Thus, the objective of this study was to assess the cost-effectiveness of second-line treatment options for patients with advanced or metastatic gastric cancer. DESIGN: Cost-effectiveness analysis using a Markov model to compare the cost-effectiveness of six possible second-line treatment options for patients with advanced gastric cancer who have failed previous chemotherapy: irinotecan, docetaxel, paclitaxel, ramucirumab, paclitaxel plus ramucirumab, and palliative care...

INTRODUCTION: Patients with metastatic hormone sensitive prostate cancer (mHSPC) have traditionally been treated with androgen deprivation therapy (ADT). Recently, there has been a demonstration of a survival benefit with the addition of docetaxel to ADT from three large randomized controlled trials. This review summarizes these trials, draws comparisons between the trials, and attempts to provide critical evidence-based recommendation on the role of docetaxel in mHSPC. METHODS: Of the two published (GETUG-AFU, Chemo-Hormonal therapy vs...

We aimed at exploring block copolymer micelles (BCMs) for the simultaneous delivery of radiation/chemotherapy to cancer cells. To achieve that goal, we have prepared and characterized a novel type of docetaxel (DTX) loaded and non-loaded BCMs. The micelles were decorated with pyrazolyl-diamine chelating units to stabilize the matched pair (99m)Tc/Re for image-guided delivery of therapeutic drugs. The in vitro studies have shown that DTX release is pH-dependent increasing at lower pH values. Anti-proliferative studies in different cancer cell lines showed that DTX-loaded BCMs present relevant anti-proliferative activity...

Importance: Standard dosing of chemotherapy based on body surface area results in marked interpatient variation in pharmacokinetics, toxic effects, and efficacy. Whether tailored dosing can improve outcomes is unknown, as is the role of dose-dense adjuvant chemotherapy. Objective: To determine whether tailored dose-dense adjuvant chemotherapy improves the outcomes of early breast cancer compared with a standard 3-weekly chemotherapy schedule. Design, Setting, and Participants: A randomized, open-label, phase 3 trial of women aged 65 years and younger who had surgery for nonmetastatic node-positive or high-risk node-negative breast cancer at 86 sites in Sweden, Germany, and Austria between February 20, 2007, and September 14, 2011...

BACKGROUND: Up to a fifth of patients diagnosed with prostate cancer (PC) will develop castration-resistant prostate cancer (CRPC), which has been associated with a poor prognosis. The aim of this study was to consider the patient perspective as part of the overall treatment decision-making process for CRPC, given that an alignment between patient preference and prescribing has been shown to benefit patient outcomes. This study examines preferences of patients with CRPC in Japan for treatment features associated with treatments like RA-223, abiraterone, and docetaxel and to examine the extent to which treatment preferences may vary between symptomatic and asymptomatic patients...

BACKGROUND/AIM: Recent studies have shown that an early prostate-specific antigen (PSA) response to androgen receptor (AR)-targeting agents in metastatic castration-resistant prostate cancer (mCRPC) is associated with a better prognosis. We analyzed early PSA response to enzalutamide and oncological outcomes to study their prognostic significance in the Japanese population. PATIENTS AND METHODS: Fifty-one patients with mCRPC (26 of pre-docetaxel and 25 of post-docetaxel status) were treated with enzalutamide...

BACKGROUND: Due to the high rate of febrile neutropenia (FN) with docetaxel-cyclophosphamide (DC) chemotherapy, primary FN prophylaxis is recommended. However, the optimal choice of prophylaxis [i.e., granulocyte-colony stimulating factors (G-CSF) or antibiotics] is unknown. A systematic review was performed to address this knowledge gap. METHODS: Embase, Ovid Medline, Pubmed, the Cochrane database of systematic reviews, and Cochrane register of controlled trials were searched from 1946 to April 2016 for studies evaluating primary prophylactic FN treatments in breast cancer patients receiving DC chemotherapy...

Triple-negative breast cancers(TNBCs)are associated with early recurrence after surgery and unfavorable prognoses. To date, no effective therapies for TNBCs have been established. The present study was designed to evaluate the efficacy of adjuvant chemotherapy(ACT)for 111 TNBCs using a retrospective multivariate analysis(MVA). The intravenous(iv)ACTs included docetaxel, epirubicin, gemcitabine, and vinorelbine. The oral ACTs included UFT, doxifluridine, and cyclophosphamide. The 10-year disease-free survival(DFS)and overall survival(OS)rates were 77...

Postoperative chemotherapy was initially conducted with surgical treatment as part of a multimodal treatment strategy for esophageal squamous cell carcinoma. Subsequently, a randomized trial comparing post- versus pre-operative chemotherapy with cisplatin and 5-fluorouracil demonstrated the superior efficacy of neoadjuvant treatment with FP(CF). However, the results of subgroup analysis based on T factor revealed no efficacy for cT3 tumors. To improve the survival rate in patients with cT3 tumors, treatments with neoadjuvant chemotherapy using FP(CF)plus docetaxel and concurrent FP(CF)plus radiation were conducted to assess the feasibility of preoperative adjuvant treatment and surgery after neoadjuvant treatment...
