Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. It starts in the lining of the small kidney tubes that filter blood. Doctors often find it by chance on a scan done for another reason.

Treatment has improved a lot in recent years, but many patients still do not respond well to current drugs. Renal Cell Carcinoma Tissue Samples help researchers understand why, and they support the search for better treatments.

At Bay Biosciences, we provide high-quality human biospecimens that support kidney cancer research. These include RCC Tissue Samples, Kidney Cancer Tissue Samples, Human Kidney Tumor Samples, and other Renal Cancer Biospecimens.

Understanding Renal Cell Carcinoma

RCC starts in the lining of the tiny tubes inside the kidney that filter blood. Pathologists divide it into several subtypes based on how the cells look under a microscope and what genetic changes they carry:

  • Clear cell RCC: This is the most common subtype, and it accounts for over 75% of cases.
  • Papillary RCC: This subtype forms finger-like growths and is the second most common.
  • Chromophobe RCC: This is a rarer subtype with a generally better outlook.
  • Rarer types: These include collecting duct and unclassified RCC.

Each subtype has its own genetic changes. Clear cell RCC, for example, often involves loss of the VHL gene, which affects how cells respond to low oxygen.

Symptoms of Renal Cell Carcinoma

Early RCC often causes no symptoms. When symptoms appear, they can include:

Causes and Risk Factors of Renal Cell Carcinoma

Doctors do not know the exact cause of most kidney cancers, but several factors raise the risk. 

Smoking, obesity, and long-term high blood pressure are the best known.

Similarly, chronic kidney disease also increases the risk, especially in patients on long-term dialysis. 

Moreover, inherited conditions, such as Von Hippel-Lindau disease, can cause kidney tumors at a younger age.

Similarly, exposure to certain industrial chemicals at work has also been linked to the disease.

Finally,  RCC is more common in men and in people over 60.

Diagnosis of Renal Cell Carcinoma

Doctors usually start with a physical exam and a review of the patient’s history. Urine and blood tests follow. These tests do not confirm RCC, but they can show blood in the urine or signs of poor kidney function.

Imaging is the key step. Ultrasound, CT, and MRI show the size and location of a kidney mass. A CT scan can often tell whether a mass is likely to be cancer. In some cases, doctors also take a needle biopsy.

After surgery, pathologists examine the tumor tissue. They identify the subtype and grade the tumor, which helps predict how it will behave. Staging then shows whether the cancer has spread beyond the kidney.

This pathology work depends on well-preserved tissue, which is why researchers value tissue banked as FFPE blocks and fresh-frozen samples. Both are central to Oncology Biospecimens research.

Treatment of Renal Cell Carcinoma

Doctors use different types of treatment methods for RCC, based on the patient’s condition.

Firstly, surgery is the main treatment for localized RCC. A partial nephrectomy removes the tumor and keeps the rest of the kidney, while a radical nephrectomy removes the whole kidney. 

Secondly, doctors may also use ablation to destroy small tumors with heat or cold. For very small tumors, they sometimes choose active surveillance and monitor the mass closely.

Thirdly, for advanced RCC, doctors use systemic therapy. This includes immune checkpoint inhibitors and targeted drugs that block blood vessel growth, often in combination. Some patients with VHL disease also receive a drug that targets the HIF pathway.

It is also important to highlight that not every patient responds, and resistance is common. 

Researchers use Human Cancer Tissue Samples to study why some tumors resist treatment and to find new drug targets.

Applications of Renal Cell Carcinoma Tissue Samples for Research

RCC Tissue Samples

Our high-quality RCC Tissue Samples let researchers study tumor structure, gene expression, and the surrounding immune environment. Single-cell studies of fresh tumor and matched healthy tissue have revealed new cell types in the clear cell RCC tumor environment.

Fresh Frozen Kidney Tumor Tissue

Fresh Frozen Kidney Tumor Tissue preserves DNA, RNA, and proteins well. This makes it a strong choice for sequencing, transcriptomics, and proteomics.

FFPE Kidney Cancer Samples

Good quality FFPE Kidney Cancer Samples are valuable because they keep tissue structure intact for histology and immunohistochemistry. 

Kidney Cancer Research Samples

Kidney Cancer Research Samples with matched clinical data help link tumor biology to patient outcomes. Researchers can use them for various purposes such as biomarker discovery, drug response studies, and therapy development.

Frequently Asked Questions

What are Renal Cell Carcinoma Tissue Samples used for?

Researchers use them to study tumor biology, classify subtypes, and find biomarkers. They also support drug discovery and diagnostics development.

Can researchers compare tumor samples with healthy controls?

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

Are Bay Biosciences’ human biospecimens ethically sourced?

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