Liver cancer biological samples:
Research application and procurement
The development of drugs and diagnostic tests for the treatment and detection of liver cancer requires conducting studies on biological samples obtained from patients with liver cancer.
A brief overview of the various types of liver cancer and how the services offered by Labtoo contribute to accelerating research and development projects in the pharmaceutical industry.

What are liver tumors?
The liver, as a key organ in the digestive system, assumes several crucial functions in the body. It plays an active role in the metabolism of nutrients, regulation of hormonal levels, and detoxification by filtering harmful substances. These processes significantly contribute to maintaining homeostasis, thereby ensuring overall physiological balance.
The major primary cancers of the liver are distinguished into two types, differentiated by their originating cells.
Hepatocellular carcinoma (HCC)
Constituting approximately 85% of liver cancers, arises from the transformation of hepatocytes, the main liver cells.
Risk factors associated with HCC include infections with hepatitis B and C, cirrhosis, and alcoholism.
Various variants of HCC, such as fibrolamellar hepatocellular carcinoma, scirrhous, pleomorphic, or sarcomatoid carcinoma, are identified based on their specific morphology.
Cholangiocarcinoma
Less common, originates from the epithelial cells of the bile ducts, known as cholangiocytes.
| Type of Liver Cancer | Originating Cells | Frequency |
|---|---|---|
| Hepatocellular Carcinoma (HCC) | Hepatocytes | 85% |
| Fibrolamellar HCC | Hepatocytes | Rare |
| Scirrhous HCC | Hepatocytes | Rare |
| Pleomorphic HCC | Hepatocytes | Rare |
| Sarcomatoid HCC | Hepatocytes | Rare |
| Cholangiocarcinoma | Cholangiocytes | 10% |
Due to its significant vascularization, the liver is frequently the site of metastases. Colorectal, breast, lung, gastric, and other cancers can metastasize to the liver. The distinction between primary and metastatic cancer is crucial due to its impact on therapeutic choices and prognosis.

Types of available samples
Fresh tissues
After a tumor resection or a biopsy, a pathologist can decide whether the tissue sample can be used for research. Labtoo can organize the conditioning and shipment of fresh liver cancer tissue in 24-48 hours after surgery.
Frozen tissues (OCT and FF)
Similarly to fresh tissue, once the tissues are cleared for research, the clinical site can freeze and keep the frozen liver cancer tissue samples at -80°C or in liquid nitrogen for ulterior use.
FFPE Tissues
Pathologists typically embed the biopsies and resections in paraffin. FFPE blocks of liver cancer tissues can be used later for research.
Adjacent Healthy Tissues
Tumor resections typically include healthy adjacent liver tissue during the process. This tissue can later be used for research and act as controls for diseased tissues.

The stages and grades of liver cancer
The stage and grade of cancer are commonly used together to provide a comprehensive evaluation of the disease and guide optimal treatment.
The determination of the cancer stage relies primarily on the TNM classification, which assesses the size of the tumor (T), the involvement of lymph nodes by cancer cells (N), and the presence of metastases in other parts of the body (M).
Concurrently, the grade provides an indication of the degree of differentiation of cancer cells. Noted from 1 to 3, Grade G1 indicates well-differentiated cells resembling normal cells, Grade G2 represents moderately differentiated cells, and Grade G3 indicates poorly differentiated cells, suggesting faster and potentially more aggressive growth.
For liver cancer, the Barcelona Clinic Liver Cancer (BCLC) classification is commonly used, defining 4 stages A, B, C, D:
Stage 0
Observation of a tumor 2 cm or less, causing no symptoms, and not invading major blood vessels of the liver.
Stage A
Observation of up to 3 tumors, each less than 3 cm, no symptoms, and no invasion of major blood vessels of the liver.
Stage B
Observation of more than 3 tumors in the liver or 1 to 3 tumors, with at least one larger than 3 cm, no symptoms, and no invasion of major blood vessels of the liver.
Stage C
Invasion of major blood vessels of the liver or spread outside the liver to other parts of the body, causing symptoms.
Rare forms of liver cancer
Occasionally, rare forms of liver cancer develop, among which are:
-
Hepatic Angiosarcoma
This cancer type develops from endothelial cells lining the blood vessels of the liver.
-
Hepatoblastoma
It arises from embryonic cells of the liver and predominantly affects children.
-
Hepatic Neuroendocrine Carcinoma
A highly uncommon case, the tumor originates from neuroendocrine cells of the liver.
Liver cancer treatments and advances
The treatment of liver cancer depends on various parameters, particularly the stage of the disease. For cancers diagnosed at stage A, surgery is typically preferred, involving partial resection of the affected liver or potentially liver transplantation. Chemotherapy is often considered in conjunction with surgery to prevent relapses.
In cases where surgery is not possible or insufficient, different therapeutic alternatives may be considered, such as radiotherapy, cryoablation, and percutaneous radiofrequency tumor destruction.
For cancers classified at stage B, chemoembolization approaches can be used to obstruct the tumor's blood supply.
Immunotherapy has also demonstrated its efficacy in treating advanced liver cancer. It is frequently integrated into targeted therapy strategies, in combination with anti-tumor agents such as bevacizumab or sorafenib.
