Models of spontaneous metastatic renal cell carcinoma (RCC) disease progression can be used for evaluating treatments in a clinically relevant setting. This protocol demonstrates different procedures for orthotopic kidney tumor cell implantation, proper nephrectomy, and finally outlines a necropsy guide for visual and bioluminescent scoring of metastatic burden and localization.

The ability of metastatic clones to colonize distant sites depends on their proliferation capacity and/or their ability to survive in the host microenvironment without significant proliferation. Here, we present an animal model that allows quantitative visualization of both types of liver colonization by metastatic clones.

FAQs
A new tissue must provide a supportive microenvironment for disseminated cancer cells to establish and grow. This makes organ-specific colonization an important research focus rather than treating spread as uniform throughout the body. Studying these local conditions can help explain why metastatic lesions develop in particular tissues and may identify opportunities to limit their expansion.
Metastatic progression depends on several linked stages, including tissue invasion, vascular entry, survival during circulation, exit into a new site, and subsequent growth. Examining these steps helps researchers determine where dissemination may be interrupted. This staged view also connects cellular behavior with disease progression and the development of treatments intended to limit spread.
Molecular profiling provides information about the biological features of metastatic lesions and can support their evaluation alongside imaging and biopsy. In cancer research, these data help investigators study dissemination and therapy resistance. Comparing molecular findings with lesion location and clinical assessment can contribute to treatment planning and to the development of more targeted approaches.
Metastatic lesions are studied in part because they can be associated with resistance to therapy, making disease control more difficult. Research examines these lesions to clarify how cancer progression and treatment response are connected. Experimental models and molecular profiling can then support evaluation of targeted treatments designed to improve control and limit further spread.
Identification commonly combines imaging, biopsy, and molecular profiling rather than relying on a single source of information. Imaging helps locate suspicious lesions, while biopsy and molecular analysis provide additional evidence about their characteristics. Together, these approaches support assessment of disease extent, treatment planning, and research into how metastatic disease develops.
A typical investigation brings together lesion detection, tissue assessment, molecular characterization, and experimental modeling. Researchers use these complementary approaches to examine dissemination, organ-specific colonization, and responses to targeted treatments. The combined evidence can clarify disease biology while also indicating whether an intervention may help limit spread or improve disease control.
Experimental models are useful when investigators need to study metastatic processes or evaluate treatments under controlled research conditions. They support investigations of tumor cell dissemination, growth at new sites, and treatment response. In this context, models complement imaging, biopsy, and molecular profiling by allowing targeted therapies intended to limit spread to be assessed.
Their presence provides information about cancer progression and the extent of disease, making them important to staging. That information can influence how treatment is planned and how disease control is assessed. In cancer research, lesion analysis also connects clinical decision-making with studies of dissemination, organ-specific colonization, and therapies designed to address metastatic spread.
