BACKGROUND Metformin, an antidiabetic drug, decreases the incidence of various cancers in diabetic patients. Metformin-induced inhibition of cancer cell proliferation has been confirmed in vitro but not in humans. Because endometrial cancer is associated with insulin resistance, the authors investigated whether a diabetes-therapeutic metformin dose inhibits(More)
OBJECTIVES The objectives of the current investigation were two-fold: (1) to examine the effect of different powder/liquid (P/L) ratios on the fracture toughness of commercial resin-modified glass ionomer cement and conventional glass ionomer cement, and (2) to evaluate the effect of powder size reduction on the fracture toughness of experimental(More)
The authors retrospectively reviewed the medical records of 129 patients with stage IB and II cervical cancer (93 squamous cell carcinomas, 30 adenocarcinomas, and 6 adenosquamous carcinomas) who underwent primary surgery between 1989 and 2000. Vascular invasion is the predictor of recurrence, and lymphocytic infiltrates within the tumor is associated with(More)
In developed countries, endometrial cancer (EC) is the most common malignancy among women. Unopposed estrogen therapy, obesity, nulliparity, diabetes mellitus and arterial hypertension have been linked to an increased risk of EC. However, the molecular mechanisms of EC oncogenesis and metastasis have not yet been fully elucidated. Our recent studies of(More)
BACKGROUND Vascular endothelial growth factor (VEGF) and VEGF-C play a crucial role in the regulation of tumor growth and metastasis. The current study examined the significance of serum VEGF and VEGF-C levels in relation to conventional clinicopathologic parameters, response to treatment, and survival in patients with cervical carcinoma. METHODS Between(More)
OBJECTIVE To evaluate the efficacy and safety of etoposide/methotrexate/actinomycin D (MEA regimen) as initial chemotherapy and 5-fluorouracil/actinomycin D (FA regimen) as salvage chemotherapy for high-risk gestational trophoblastic tumor (GTT). STUDY DESIGN From 1985 to 2001, 36 patients with World Health Organization (WHO)--defined high-risk GTT were(More)
OBJECTIVE To analyze the outcome of the first pregnancy following chemotherapy for gestational trophoblastic tumor (GTT). STUDY DESIGN A total of 393 patients with GTT (87 with high-risk and 306 with low-risk GTT) underwent chemotherapy at Chiba University Hospital between 1974 and 2000. Of them, 137 (19 with high-risk and 118 with low-risk GTT) who(More)
Metformin is a diabetes drug with anticancer properties. Several studies have investigated the effects of metformin combined with chemotherapeutic agents, with controversial results. This study evaluated the efficacy of combined metformin/cisplatin treatment in an endometrial cancer cell line. Ishikawa cells were treated with metformin, cisplatin or both(More)
