About the OVA1 Test
The OVA1 Test is a qualitative serum test that combines the results of five immunoassays into a single numerical score. It is indicated for women who meet the following criteria: over age 18, ovarian adnexal mass present for which surgery is planned, and not yet referred to an oncologist. The test utilizes five well-established biomarkers --- Transthyretin (TT or prealbumin), Apolipoprotein A-1 (Apo A-1), Beta2-Microglobulin (Beta2M), Transferrin (Tfr) and Cancer Antigen 125 (CA 125 II) --- and a proprietary algorithm to determine the likelihood of malignancy in women with pelvic mass for whom surgery is planned.

"We are also considering a randomized Phase 2 clinical trial investigating OGX-427 in ovarian cancer," said Scott Cormack, President and Chief Executive Officer of OncoGenex."

Somatic TP53 mutations occur in almost every type of cancer at rates from 38%–50% in ovarian and..........TP53 mutations, but not p53 positive immunohistochemistry (IHC), have been consistently associated with poor prognosis in cancers such as breast, colorectal, head and neck, and leukemia.....In terms of clinical applications, TP53 mutations have proven to be extremely complex biomarkers. Despite impressive progress in mechanistic understanding of p53 structure and function, p53 research has not yet generated applications of wide impact on cancer management and therapy."

abstract/full text: Gene silencing of glypican-3 in clear cell carcinoma of the ovary renders it more sensitive to the apoptotic agent paclitaxel
"Clear cell carcinoma has been classified as a subgroup of EOC and reported to be an interesting histologic type with unique clinical features. CCC showed a poorer prognosis compared to serous adenocarcinoma because it tended to be resistant to antineoplastic agents, including paclitaxel.
CCC comprises more than 15% of EOC cases in Japan, although it represents 8–10% of all EOC cases in the USA. Therefore, it is important to establish new treatment strategies to improve the prognosis of CCC patients.
GPC3 regulates cell growth either positively or negatively depending on the cell type. Genetic and functional studies showed that glypicans regulate the signaling activity of various morphogens, including Wnts, Hedgehogs, bone morphogenic proteins, and fibroblast growth factors. Previous studies showed that GPC3 was overexpressed in Wilms' tumor, hepatocellular carcinoma, and hepatoblastoma. In ovarian carcinoma, GPC3 was overexpressed in yolk sac tumor and CCC.(15–17) However, GPC3 function in CCC was unclear. Furthermore, we investigated the role of this molecule in the sensitivity of CCC to paclitaxel, which is a key drug for ovarian cancer, using shRNA targeting GPC3.
Taken together, our data could support the use of GPC3-targeted therapies for CCC patients. We suggest that therapy targeting to GPC3 may be a novel treatment strategy that could potentially help to prevent the appearance, progression, and/or recurrence of CCC."

New platinum compound shows promise in tumor cells-in research Milaplatin combination
New platinum compound shows promise in tumor cells
"The new compound, mitaplatin, combines cisplatin with another compound, dichloroacetate (DCA), which can alter the properties of mitochondria selectively in cancer cells. Cancer cells switch their mitochondrial properties to change the way they metabolize glucose compared to normal cells, and DCA specifically targets the altered mitochondria, leaving normal cells intact."

"If chemotherapy is indicated, we recommend delaying administration, if possible, until after the delivery or at least after 20 weeks in order to minimize the potential fetal toxicity".
Does the use of diagnostic PET/CT cause stage migration in patients with primary advanced ovarian cancer?
Note: It's unfortunate that early stages of ovarian cancers were not included in this study.
