Market Overview

The global circulating tumor cells (CTC) market size was valued at USD 10.7 billion in 2022. It is estimated to reach USD 25.65 billion by 2031, growing at a CAGR of 10.2% during the forecast period (2023–2031). Advancements in chip technology and expanding applications of CTCs propel market growth.

The term "circulating tumor cells" (CTC) refers to cells that have broken away from a primary tumor and entered the circulation or lymphatic system, allowing them to circulate throughout the body. They can be found in cancer patients' peripheral blood and are expelled by solid tumors. When cancer spreads from the main tumor to other parts of the body, a process called metastasis, CTCs play a critical part. The fact that CTCs provide a non-invasive way to track the development of the disease predict the effectiveness of treatment, and determine prognosis makes them of tremendous interest in cancer research and clinical practice.

The characteristics of the tumor, such as genetic alterations, protein expression, and patterns of medication resistance, can be learned a great deal by extracting and examining CTCs. This information can benefit a targeted therapy's development and patient treatment decisions. As CTCs are uncommon and common blood cells are present in blood samples, it is difficult to isolate and detect CTCs. High sensitivity and specificity CTC capture and analysis have been made possible by several methods, including immunological approaches and microfluidic devices.

Market Dynamics

Global circulating tumor cells (ctc) market drivers

Advancements in chip technology

The continued development of chip technology has benefited market expansion. Circulating tumor cells (CTCs), an extremely rare cell class, are captured partly through cluster chip technology. The method of CTC isolation is laborious and highly accurate. The chip technology facilitates accurate CTC isolation but also aids in resolving issues with isolation devices created by significant corporations. The difficulties include low sensitivity, inability to catch CTCs of various shapes and sizes, high production costs, and difficulty removing collected CTCs from the devices for additional laboratory examination.

Additionally, a drawback of these devices is that the white blood cells that infect confined CTCs can be mistaken for CTCs due to their comparable size. As a result of these technological improvements, CTC research is expected to see an increase in demand for customizing preventive medication for cancer therapy. Several researchers discovered that the cluster-chip method is more effective than a microfluidic chip, which featured CTC isolation using antibodies that adhere to the unique proteins on a tumor cell's surface. Another advantage of this technology is that cluster chip has no adverse effects on CTC clusters. These elements will propel chip development for CTC isolation and revenue growth.

Expanding applications of ctcs

CTCs are used in cancer care for early detection, risk assessment, therapeutic counseling, VVBHCASKD, and ongoing monitoring. The use of CTCs is anticipated to increase throughout the projected period due to the development of numerous tumor markers employing CTCs. Prostate cancer can be accurately and affordably monitored thanks to quantification and genomic profiling of CTCs noninvasively, and their identification can predict the prognosis for a cancer patient's survival. Precision medicine has evolved, and new drug development options have been made possible by the molecular profiling of CTCs for androgen receptor variations. The desire for customized medicine has increased due to the growing desire for early disease detection, drug safety, cost savings, patient compliance, and therapy optimization.

The huge demand for CTC detection tests is also a result of people's growing preference for companion diagnostics. More than 150 tailored medicines are based on CTCs and companion diagnostic on-label combinations in clinical development. Throughout the forecast period, the market is anticipated to be driven by increased cancer-related spending on companion diagnostics and tailored medications.

Global circulating tumor cells (ctc) market restraint

Lower applicability of ctcs in rare cancers

The limited utility of CTCs in uncommon tumors is another reason for limiting expansion. Technically speaking, CTC research is still difficult due to their rarity—only a few are found in a milliliter of peripheral blood. They are not the only uncommon blood cell and have a highly varied phenotypic characteristics. Atypical non-tumor cells, epithelial and non-epithelial non-tumor cells, endothelial cells, and other uncommon circulating cells, such as stem cells, should be separated from CTCs when they are isolated and studied because of this. The diverse category of malignant neoplasms known as sarcomas has a propensity to spread to distant organs.

However, the characterization of CTCs associated with sarcoma is still relatively limited due to the rarity of these tumors and the lack of distinct sarcoma tumor markers. A barrier to accurately detecting CTCs relevant to uncommon sarcomas is the incomplete understanding of the precise makeup of cancer stem cells and their interaction with CTCs. On the other hand, several approaches are being researched for CTC isolation, including approaches based on epithelial antigen-targeted antibodies, which are anticipated to aid in overcoming these difficulties in the next years.
