Ovarian cancer is one of the most lethal gynecologic cancers. It is often found late, and many patients are diagnosed at advanced stages. Researchers therefore need well-characterized Ovarian Cancer Plasma and Serum Samples to find better ways to detect, monitor, and treat the disease.

At Bay Biosciences, we understand this need and provide high-quality human biospecimens that support gynecologic cancer research. 

These include Ovarian Cancer Plasma Samples, Ovarian Cancer Serum Samples, Ovarian Tumor Samples, Ovarian Cancer Blood Samples, and other Ovarian Cancer Biospecimens. We also supply other gynecologic cancer samples, such as Uterine Cancer Samples and Cervical Cancer Samples.

Understanding Ovarian Cancer

Ovarian cancer starts in the ovaries, the organs that make eggs and female hormones. Most cases are epithelial, meaning the cancer begins in the cells that cover the ovary’s surface. 

Rarer types include germ cell tumors and stromal tumors.

Epithelial ovarian cancer is not one disease. High-grade serous ovarian cancer (HGSC) is the most common subtype. 

Other subtypes, such as endometrioid and mucinous tumors, differ in their genes and in how they respond to treatment. Because of this variety, researchers need Ovarian Cancer Biospecimens with detailed clinical data to link tumor biology to patient outcomes.

Symptoms of Ovarian Cancer

Early ovarian cancer often causes vague symptoms that are easy to miss. As the disease grows, patients may notice:

In advanced disease, fluid can build up in the abdomen, a problem called ascites. However, these symptoms can also appear in many other conditions. Doctors need further testing to confirm ovarian cancer.

Causes and Risk Factors of Ovarian Cancer

In most patients, doctors cannot find a single clear cause. Still, several factors raise the risk. 

Age is one of them, because the disease is more common after menopause and in older women.

Similarly, Family history also matters, especially a history of ovarian or breast cancer.

Moreover, Genetic changes explain part of this risk. Inherited faults in the BRCA1 and BRCA2 genes are a major risk factor, and they are found in about 20% of high-grade serous cancers. 

Furthermore, mutations linked to Lynch syndrome, which is better known for colon cancer, also raise the risk. 

Other factors include endometriosis and never having given birth. On the other hand, breastfeeding and birth control pills can lower the risk.

Diagnosis of Ovarian Cancer

Doctors usually begin with a review of symptoms, family history, and a pelvic exam. A transvaginal ultrasound often follows. CT scans or MRI can then show how far the disease has spread.

Blood tests are also part of the work-up. The most common one measures the protein CA-125. 

However, CA-125 has clear limits. Levels can also rise with uterine fibroids, endometriosis, and liver disease or kidney disease, and some ovarian cancers do not raise it at all. Experts do not recommend routine screening with this test for women at average risk.

However, it is important to highlight that a definitive diagnosis usually comes from surgery. The surgeon removes tissue, and a pathologist examines it to confirm the cancer type and stage. A biopsy may be used first in some cases.

Treatment of Ovarian Cancer

Surgery is the main treatment. The goal is to remove as much of the cancer as possible. Chemotherapy usually follows, and the standard regimen includes platinum-based drugs. If the cancer has spread widely, doctors may give chemotherapy before surgery to shrink the tumor.

Newer options add targeted treatment. PARP inhibitors are oral drugs that block an enzyme cells use to repair DNA damage, and they work especially well in tumors with BRCA mutations. Bevacizumab, which blocks the growth of new blood vessels, is another option. 

Overall, the treatment plans depend on the cancer type, stage, and the patient’s health. Researchers use human cancer tissue samples to test new targets and understand why some tumors resist treatment.

Applications of Ovarian Cancer Plasma and Serum Samples for Research

Human Plasma Samples and Human Serum Samples are both made from blood, but they are not the same. 

Plasma comes from blood collected with an anticoagulant, while serum comes from clotted blood and contains no clotting factors. Researchers choose the one that fits their assay, and a standard serum and plasma protocol keeps processing consistent.

Biomarker discovery is one of the main uses. 

Studies have compared serum from women with ovarian cancer to serum from healthy controls and found dozens of proteins that differ between the two groups. 

Other work found that junction plakoglobin combined with CA-125 could improve early detection. This fits the wider need for Cancer Biomarker Samples.

Plasma and serum also support liquid biopsy studies. Liquid Biopsy Research uses blood to look for circulating tumor DNA and other tumor-derived markers. It is less invasive than a tissue biopsy and allows repeated sampling to track the disease over time. 

Other Oncology Biofluid Samples, such as ovarian cancer ascites samples, give researchers more ways to study the disease.

Many studies also need Human Blood Samples from healthy donors as controls. Comparing disease samples with healthy controls helps researchers separate true cancer signals from normal variation.

Frequently Asked Questions

What are Ovarian Cancer Plasma and Serum Samples used for?

Researchers use them to discover biomarkers, study tumor biology, and test new diagnostic 

assays. They also support drug discovery, liquid biopsy research, and translational studies.

Do you provide matched tissue with the plasma and serum samples?

Yes. We offer matched fresh-frozen tissue, FFPE tissue samples, and peripheral blood mononuclear cells (PBMCs) from patients with ovarian cancer.

Can researchers compare ovarian cancer samples with healthy controls?

Yes. Researchers can compare disease samples with normal healthy donor samples to find differences in biomarkers.

Are Bay Biosciences’ human biospecimens ethically sourced?

Yes. We collect all human samples through appropriate consent and IRB-approved protocols.
