Early palliative care for patients with advanced cancer: a cluster-randomised controlled trial.

Background: Patients with advanced cancer have reduced quality of life, which tends to worsen towards the end of life. We assessed the effect of early palliative care in patients with advanced cancer on several aspects of quality of life.

Methods: The study took place at the Princess Margaret Cancer Centre (Toronto, ON, Canada), between Dec 1, 2006, and Feb 28, 2011.

A phase II trial of saracatinib, an inhibitor of src kinases, in previously-treated advanced non-small-cell lung cancer: the princess margaret hospital phase II consortium.

Background: The src family of kinases may play a role in the malignant phenotype through effects on migration, motility, adhesion and proliferation. The activity of saracatinib, an orally available inhibitor of src kinases, was evaluated in patients with advanced, platinum-pretreated NSCLC.

Patients And Methods: Eligible patients with advanced NSCLC of any histologic subtype and who had obtained a best response to prior platinum-based chemotherapy of at least stable disease received saracatanib 175 mg orally daily in a 28 day cycle.

Molecular determinants of outcome with mammalian target of rapamycin inhibition in endometrial cancer.

Background: Targeting the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway is of increasing interest as a therapeutic strategy in many tumors. The aim of this study was to identify molecular markers associated with mTOR inhibitor activity in women with metastatic endometrial cancer.

Methods: Archival tumor samples were collected from 94 women with recurrent or metastatic endometrial cancer who participated in 3 National Cancer Insitute of Canada Clinical Trials Group phase 2 trials investigating single-agent mTOR inhibitors: IND160A and IND160B (temsirolimus) and IND192 (ridaforolimus).

Evolution of clinical trial design in early drug development: systematic review of expansion cohort use in single-agent phase I cancer trials.

Purpose: To evaluate the use and objectives of expansion cohorts in phase I cancer trials and to explore trial characteristics associated with their use.

Methods: We performed a systematic review of MEDLINE and EMBASE, limiting studies to single-agent phase I trials recruiting adults and published after 2006. Eligibility assessment and data extraction were performed by two reviewers.

Hope, quality of life, and benefit from treatment in women having chemotherapy for platinum-resistant/refractory recurrent ovarian cancer: the gynecologic cancer intergroup symptom benefit study.

Chemotherapy for platinum-resistant/refractory ovarian cancer is motivated by the hope of benefit. We sought to determine the relationships between: (a) trait hope, expectation of symptom benefit from chemotherapy, and anxiety and depression; (b) hope and perceived efficacy of chemotherapy; and (c) unfulfilled hope (where expectations for benefit are not fulfilled) and depression. Methods.

Clinical and toxicity predictors of response and progression to temsirolimus in women with recurrent or metastatic endometrial cancer.

Objective: Temsirolimus (TEM) has recently shown activity (NCIC CTG phase II trial) in endometrial cancer (EC). Despite EC having a high rate of PTEN mutation, in this trial activity was independent of PTEN and other molecular markers. We explored whether treatment related toxicity occurring in cycle one was predictive of outcomes.

Efficacy of chemotherapy in BRCA1/2 mutation carrier ovarian cancer in the setting of PARP inhibitor resistance: a multi-institutional study.

Purpose: Preclinical data suggest that exposure to PARP inhibitors (PARPi) may compromise benefit to subsequent chemotherapy, particularly platinum-based regimens, in patients with BRCA1/2 mutation carrier ovarian cancer (PBMCOC), possibly through the acquisition of secondary BRCA1/2 mutations. The efficacy of chemotherapy in the PARPi-resistant setting was therefore investigated.

Experimental Design: We conducted a retrospective review of PBMCOC who received chemotherapy following disease progression on olaparib, administered at ≥200 mg twice daily for one month or more.

High tumor interstitial fluid pressure identifies cervical cancer patients with improved survival from radiotherapy plus cisplatin versus radiotherapy alone.

Radiotherapy (RT) with concurrent cisplatin (CRT) is standard treatment for locally advanced cervical cancer. However, not all patients benefit from the addition of cisplatin to RT alone. This study explored the value of pretreatment tumor interstitial fluid pressure (IFP) and hypoxia measurements as predictors of cisplatin response in 291 patients who were treated with RT (1994-1998) or RT plus concurrent cisplatin (1999-2009).

A phase Ib combination study of RO4929097, a gamma-secretase inhibitor, and temsirolimus in patients with advanced solid tumors.

Background: To determine the recommended phase II dose (RP2D) and assess the safety, pharmacokinetics (PKs) and pharmacodynamics of RO4929097in combination with temsirolimus.

Methods: Escalating doses of RO4929097 and temsirolimus were administered at three dose levels. Patients received once daily oral RO4929097 on a 3 days on/4 days off schedule every week, and weekly intravenous temsirolimus.

Testing personalized medicine: patient and physician expectations of next-generation genomic sequencing in late-stage cancer care.

Developments in genomics, including next-generation sequencing technologies, are expected to enable a more personalized approach to clinical care, with improved risk stratification and treatment selection. In oncology, personalized medicine is particularly advanced and increasingly used to identify oncogenic variants in tumor tissue that predict responsiveness to specific drugs. Yet, the translational research needed to validate these technologies will be conducted in patients with late-stage cancer and is expected to produce results of variable clinical significance and incidentally identify genetic risks.

Hormone-receptor expression and ovarian cancer survival: an Ovarian Tumor Tissue Analysis consortium study.

Background: Few biomarkers of ovarian cancer prognosis have been established, partly because subtype-specific associations might be obscured in studies combining all histopathological subtypes. We examined whether tumour expression of the progesterone receptor (PR) and oestrogen receptor (ER) was associated with subtype-specific survival.

Methods: 12 studies participating in the Ovarian Tumor Tissue Analysis consortium contributed tissue microarray sections and clinical data to our study.

A phase I study of the oral gamma secretase inhibitor R04929097 in combination with gemcitabine in patients with advanced solid tumors (PHL-078/CTEP 8575).

Purpose: To establish the recommended phase II dose of the oral γ-secretase inhibitor RO4929097 (RO) in combination with gemcitabine; secondary objectives include the evaluation of safety, tolerability, pharmacokinetics, biomarkers of Notch signaling and preliminary anti-tumor activity.

Methods: Patients with advanced solid tumors were enrolled in cohorts of escalating RO dose levels (DLs). Tested RO DLs were 20 mg, 30 mg, 45 mg and 90 mg.

A randomized phase II trial of maintenance therapy with Sorafenib in front-line ovarian carcinoma.

Objectives: Sorafenib, an oral multikinase inhibitor of the VEGFR/PDGFR/Raf/MEK/ERK pathway, has shown potential activity in patients with recurrent ovarian cancer (OC). One strategy to prolong disease control and survival in patients with OC is maintenance therapy after achieving a complete response. A double-blind, randomized, placebo-controlled, phase II study to assess the efficacy and safety of maintenance therapy with sorafenib in the treatment of OC is presented.

Standard chemotherapy with or without bevacizumab in advanced ovarian cancer: quality-of-life outcomes from the International Collaboration on Ovarian Neoplasms (ICON7) phase 3 randomised trial.

Background: In the Gynecologic Cancer Intergroup International Collaboration on Ovarian Neoplasms 7 (ICON7) trial, bevacizumab improved progression-free survival in patients with ovarian cancer when used in combination with first-line chemotherapy and as a single-drug continuation treatment for 18 cycles. In a preliminary analysis of a high-risk subset of patients, there was also an improvement in overall survival. This study aims to describe the health-related quality-of-life (QoL) outcomes from ICON7.

ENMD-2076, an oral inhibitor of angiogenic and proliferation kinases, has activity in recurrent, platinum resistant ovarian cancer.

Purpose: The purpose was to assess the activity and side effect profile of ENMD-2076, an oral anti-angiogenic and anti-proliferative kinase inhibitor, in platinum-resistant recurrent epithelial ovarian cancer (EOC), fallopian tube or peritoneal cancer. Archival tumour tissue was obtained for correlative analyses.

Experimental Design: This was an open-label single-arm Phase II study of single agent ENMD-2076 taken daily orally (PO).

Biologic rationale and clinical activity of mTOR inhibitors in gynecological cancer.

Advanced recurrent gynecological malignancies have a poor prognosis despite systemic treatment, which is usually cytotoxic chemotherapy. Responses are generally short-lived and more effective treatments are needed. Rationally designed molecularly targeted therapy is an emerging and important option in this setting.

A phase 3 trial of bevacizumab in ovarian cancer.

Background: Angiogenesis plays a role in the biology of ovarian cancer. We examined the effect of bevacizumab, the vascular endothelial growth factor inhibitor, on survival in women with this disease.

Methods: We randomly assigned women with ovarian cancer to carboplatin (area under the curve, 5 or 6) and paclitaxel (175 mg per square meter of body-surface area), given every 3 weeks for 6 cycles, or to this regimen plus bevacizumab (7.

Randomized, double-blind, placebo-controlled phase II study of AMG 386 combined with weekly paclitaxel in patients with recurrent ovarian cancer.

Purpose: To estimate the efficacy and toxicity of AMG 386, an investigational peptide-Fc fusion protein that neutralizes the interaction between the Tie2 receptor and angiopoietin-1/2, plus weekly paclitaxel in patients with recurrent ovarian cancer.

Patients And Methods: Patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer were randomly assigned 1:1:1 to receive paclitaxel (80 mg/m(2) once weekly [QW], 3 weeks on/1 week off) plus intravenous AMG 386 10 mg/kg QW (arm A), AMG 386 3 mg/kg QW (arm B), or placebo QW (arm C). The primary end point was progression-free survival (PFS).

Early mortality and overall survival in oncology phase I trial participants: can we improve patient selection?

Background: Patient selection for phase I trials (PIT) in oncology is challenging. A typical inclusion criterion for PIT is 'life expectancy > 3 months', however the 90 day mortality (90DM) and overall survival (OS) of patients with advanced solid malignancies are difficult to predict.

Methods: We analyzed 233 patients who were enrolled in PIT at Princess Margaret Hospital.

Rethinking ovarian cancer: recommendations for improving outcomes.

There have been major advances in our understanding of the cellular and molecular biology of the human malignancies that are collectively referred to as ovarian cancer. At a recent Helene Harris Memorial Trust meeting, an international group of researchers considered actions that should be taken to improve the outcome for women with ovarian cancer. Nine major recommendations are outlined in this Opinion article.

Olaparib in patients with recurrent high-grade serous or poorly differentiated ovarian carcinoma or triple-negative breast cancer: a phase 2, multicentre, open-label, non-randomised study.

Background: Olaparib (AZD2281) is a small-molecule, potent oral poly(ADP-ribose) polymerase (PARP) inhibitor. We aimed to assess the safety and tolerability of this drug in patients without BRCA1 or BRCA2 mutations with advanced triple-negative breast cancer or high-grade serous and/or undifferentiated ovarian cancer.

Methods: In this phase 2, multicentre, open-label, non-randomised study, women with advanced high-grade serous and/or undifferentiated ovarian carcinoma or triple-negative breast cancer were enrolled and received olaparib 400 mg twice a day.

Phase II study of temsirolimus in women with recurrent or metastatic endometrial cancer: a trial of the NCIC Clinical Trials Group.

Purpose: Phosphatase and tensin homolog (PTEN) is a tumor suppressor gene, and loss of function mutations are common and appear to be important in the pathogenesis of endometrial carcinomas. Loss of PTEN causes deregulated phosphatidylinositol-3 kinase/serine-threonine kinase/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling which may provide neoplastic cells with a selective survival advantage by enhancing angiogenesis, protein translation, and cell cycle progression. Temsirolimus, an ester derivative of rapamycin that inhibits mTOR, was evaluated in this setting.
