Unbalanced estrogen metabolism in ovarian cancer.

Greater exposure to estrogens is a risk factor for ovarian cancer. To investigate the role of estrogens in ovarian cancer, a spot urine sample and a saliva sample were obtained from 33 women with ovarian cancer and 34 age-matched controls. Thirty-eight estrogen metabolites, conjugates and DNA adducts were analyzed in the urine samples using ultraperformance liquid chromatography/tandem mass spectrometry, and the ratio of adducts to metabolites and conjugates was calculated for each sample.

Randomized phase III study of canfosfamide in combination with pegylated liposomal doxorubicin compared with pegylated liposomal doxorubicin alone in platinum-resistant ovarian cancer.

Objective: To evaluate the safety and efficacy of canfosfamide in combination with pegylated liposomal doxorubicin (PLD) in platinum-resistant ovarian cancer (OC).

Methods: Patients with platinum-refractory or -resistant (primary or secondary) OC were randomized to receive canfosfamide at 1000 mg/m² and PLD at 50 mg/m² intravenously or PLD alone at 50 mg/m2 intravenously on day 1 every 28 days until tumor progression or unacceptable toxicity. The primary end point was progression-free survival (PFS).

Gene expression profiling of ovarian tissues for determination of molecular pathways reflective of tumorigenesis.

Ovarian cancer is the fourth leading cause of gynecological cancer death among women in the United States. Early detection is a critical prerequisite to initiating effective cancer therapy. Gene microarray technology and proteomics have provided much of the biomarkers with potential use for diagnosis.

Concurrent carboplatin with pelvic radiation therapy in the primary treatment of cervix cancer.

Objectives: The objectives were to determine the acute toxicities of concurrent carboplatin and radiation therapy in the primary treatment of cervix cancer and to ascertain the antitumor activity of this regimen.

Methods: Patients with stage IB-1 to IVA untreated primary cervix cancers were eligible for enrollment into this study. Carboplatin was administered on a weekly basis with external radiation therapy (ERT).

A phase 2 study of the cytotoxic immunoconjugate CMB-401 (hCTM01-calicheamicin) in patients with platinum-sensitive recurrent epithelial ovarian carcinoma.

The compound CMB-401 is an immunoconjugate consisting of the monoclonal antibody (MAb) hCTM01 directed against polymorphic epithelial mucin covalently bound to the cytotoxic antibiotic calicheamicin by an amide linker. We evaluated CMB-401 as monotherapy for the treatment of recurrent platinum-sensitive epithelial ovarian carcinoma (EOC). Twenty-one 21 women aged 38 to 80 years with recurrent EOC (recurrence >6 months after initial platinum-containing chemotherapy) were enrolled.
