YM155 enhances docetaxel efficacy in ovarian cancer.

YM155 (Sepantronium bromide) is a potent small molecule inhibitor of survivin by suppression of survivin expression and shows the promising anticancer activity in many types of cancers. Docetaxel (Taxotere) is a member of the taxane drugs used in the treatment of a number of cancers in clinic. Despite the therapeutic efficacy of docetaxel is encouraging, the emergent resistance is an urgent issue.

Crizotinib synergizes with cisplatin in preclinical models of ovarian cancer.

Crizotinib, a small molecule inhibitor of anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1) and c-MET (also called MET or hepatocyte growth factor receptor), has been approved by the Food and Drug Administration for the treatment of patients with advanced non-small cell lung cancer whose tumors have rearrangements in the ALK or ROS1 gene. However, the anticancer effect of crizotinib on ovarian cancer is still unclear. In this study, our data show that crizotinib can actively induce cell growth inhibition, cell cycle arrest at G2/M phase and apoptosis with the decreasing phosphorylation of the downstream signaling effectors AKT and ERK in human ovarian cancer cells.

Volasertib suppresses tumor growth and potentiates the activity of cisplatin in cervical cancer.

Volasertib (BI 6727), a highly selective and potent inhibitor of PLK1, has shown broad antitumor activities in the preclinical and clinical studies for the treatment of several types of cancers. However, the anticancer effect of volasertib on cervical cancer cells is still unknown. In the present study, we show that volasertib can markedly induce cell growth inhibition, cell cycle arrest at G2/M phase and apoptosis with the decreased protein expressions of PLK1 substrates survivin and wee1 in human cervical cancer cells.

Evaluation of Time-Phase Effect on 18F-FDG PET/CT Delineation Methods for Treatment Planning of Nasopharyngeal Carcinoma.

Purpose: Tumor boundary delineation using F-FDG PET/CT is a promising tool for radiotherapy applications, but no consensus has been established regarding the optimal delineation method. Time-phase variability of F-FDG PET/CT imaging frequently affects metabolically active volumes and treatment planning for nasopharyngeal carcinoma (NPC). This study aimed to evaluate the time-phase robustness of 8 methods commonly used for tumor volume delineation in NPC.

Ovarian cancer initially presenting with isolated ipsilateral superficial inguinal lymph node metastasis: a case study and review of the literature.

Isolated superficial inguinal metastases without any extended intra-abdominal spread is a rare event in patients with ovarian carcinoma. Here we report an isolated superficial inguinal metastasis in a patient with primary ovarian cancer. A 54-year-old Chinese patient with primary ovarian cancer, had an isolated painless enlarged right groin swelling (3×2cm) as the only manifestation, preoperative pathology confirmed metastatic adenocarcinoma.
