Prognostic Impact of Circulating Methylated Homeobox A9 DNA in Patients Undergoing Treatment for Recurrent Ovarian Cancer.

Methylated Homeobox A9 circulating tumor DNA (meth-HOXA9) has been suggested as a blood-based biomarker in epithelial ovarian cancer (EOC), although its prognostic significance remains unproven. The aim of the present study was to investigate the prognostic impact of meth-HOXA9 in patients with recurrent EOC. DNA was purified from 4 mL plasma and, following bilsulfite conversion, meth-HOXA9 was analyzed using a methylation-specific droplet digital PCR.

Analysis of HOXA9 methylated ctDNA in ovarian cancer using sense-antisense measurement.

DNA promoter methylation is an early event in tumorigenesis and holds promise as a valuable marker in ovarian cancer (OC). It can be measured using circulating tumor specific DNA (ctDNA) isolated from the bloodstream. Sensitivity, however, is a limiting factor of its diagnostic feasibility in OC.

Carboplatin re-treatment in platinum-resistant epithelial ovarian cancer patients.

Purpose: Treatment of multi-resistant epithelial ovarian cancer represents a clinical challenge with limited choices. Anti-angiogenic therapy has shown great potential in combination with frontline-therapy. Studies investigating heavily pre-treated patients are few.

Cabazitaxel - A Treatment Option in Recurrent Platinum-resistant Ovarian Cancer.

Background/aim: Treatment of recurrent platinum-resistant ovarian cancer remains challenging due to the development of resistance to chemotherapy. Cabazitaxel is a new taxane that has demonstrated beneficial effect in prostate cancer patients resistant to docetaxel. Therefore, it could be anticipated to possibly also have an effect on chemotherapy resistant ovarian cancer.

Blood natural killer cells during treatment in recurrent ovarian cancer.

Objective: Recent research indicated favorable prognostic impact of intratumoral natural killer (NK) cells in ovarian carcinoma (OC). The role of NK cells during chemotherapy in OC is unknown. We investigated impact of NK cells in OC patients treated with palliative chemotherapy.

Prognostic significance of baseline T cells, B cells and neutrophil-lymphocyte ratio (NLR) in recurrent ovarian cancer treated with chemotherapy.

Purpose: Biomarkers are needed to guide treatment decisions in recurrent ovarian cancer, as a high proportion of patients do not benefit from treatments. Data on immune subsets in patients receiving chemotherapy are scarce. We investigated the impact of T cells, B cells, neutrophils and the neutrophil-lymphocyte ratio (NLR) in ovarian cancer patients receiving palliative chemotherapy.

Delta tocotrienol in recurrent ovarian cancer. A phase II trial.

Delta tocotrienol has anti-neoplastic activity as demonstrated in several in-vitro and in-vivo investigations. The effect relies on inhibition of different pathways. It also has antiangiogenic activity, and an additive effect to bevacizumab may be expected.

Veliparib Monotherapy to Patients With BRCA Germ Line Mutation and Platinum-Resistant or Partially Platinum-Sensitive Relapse of Epithelial Ovarian Cancer: A Phase I/II Study.

Objective: A new treatment principle, which seems to radically change the treatment approach in ovarian cancer (OC), has developed over the past few years. Poly(ADP-ribose) polymerase inhibitors work by interfering with mechanisms important to DNA damage repair. Cancer cells that already have defects in the BRCA genes are particularly sensitive to treatment with poly(ADP-ribose) polymerase inhibitors.

Prognostic importance of cell-free DNA in chemotherapy resistant ovarian cancer treated with bevacizumab.

Aim: Treatment of multiresistant epithelial ovarian cancer (EOC) is palliative and patients who have become resistant after multiple lines of chemotherapy often have an unmet need for further and less toxic treatment. Anti-angiogenic therapy has attracted considerable attention in the treatment of EOC in combination with chemotherapy. However, only a minor subgroup will benefit from the treatment and there is an obvious need for new markers to select such patients.

Serial measurements of serum PDGF-AA, PDGF-BB, FGF2, and VEGF in multiresistant ovarian cancer patients treated with bevacizumab.

Introduction: Anti-VEGF treatment has proven effective in recurrent ovarian cancer. However, the identification of the patients most likely to respond is still pending. It is well known that the angiogenesis is regulated by several other pro-angiogenic proteins, e.

A phase II study using vinorelbine and continuous 5-fluorouracil in patients with advanced head and neck cancer.

Seventy patients with advanced head and neck cancer were treated with vinorelbine and continuous 5-FU administered in a central venous catheter. Over all response was 36% with 9% complete responses. The most common grade 3 and 4 toxicities were stomatitis (13), infection (5), pain related to vinorelbine infusion (4), skin toxicity (3).
