Brief Summary

Fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) is a rare subtype of RCC characterized by germline/somatic mutation of the fumarate hydratase (FH) gene, and is an extremely aggressive tumor, with a propensity to disseminate early even in the setting of a small primary tumor.

Affected individuals or individuals suspected of having a germline FH will undergo periodic clinical assessment and genetic analyses for the purpose of: 1) definition and characterization of phenotype, 2) determination of the natural history of the disorder, and 3) genotype/phenotype correlation. Genetic linkage studies may be performed in situations in which the genetic basis of the disorder has not been elucidated.

Detailed Description

• Discovery and validation of biomarker predicting FH-deficient RCC systemic treatments response
• Analysis for expression level of ctDNA using Next generation sequencing in FH-deficient RCC blood by systemic treatments response
• Analysis for expression level of mRNA using Next generation sequencing in FH-deficient RCC tissue by systemic treatments response
• Analysis for expression level of small molecule metabolites using mass spectrometry in FH-deficient RCC tissue and blood by systemic treatments response
• Analysis for genetic and protein expression at a single-cell level using a novel flow cytometry and RNA-sequencing protocol in FH-deficient RCC tissue and blood.
• Validation of genetic and protein expression using qRT-PCR or IHC in multiple independent cohort.
• Biological biomarkers-clinical factor combined prediction model of FH-deficient RCC systemic treatments response

3. included patients must be diagnosed with metastatic renal cell carcinoma or have a TNM stage IV (according to 2009 TNM Classification);

4. new FH-RCC patients who has scheduled to start 1st cycle of systemic treatment;

5. ECOG score ≤2;

7. sign informed consent, and be able to follow the visit and related procedures stipulated in the program;

8. agree to collect tumor tissue, blood and other specimens required by this study and apply them to relevant studies;

9. Patients must have consent in place, for the use of tissue and imaging to be used for the purposes of clinical research; Use of tissue not required for their diagnosis or treatment to be stored and used for the purposes of clinical research, which may include genetic research. Use of relevant sections of their medical records, or by relevant regulatory authorities, where my tissue is being used for research, giving permission for those individuals to have access to their medical records. Participants must also meet at least one of the following criteria to be eligible: For tissue analysis: Patient must have tumour tissue and/or normal adjacent kidney stored (either as formalinfixed paraffin-embedded tissue, or as 'fresh frozen' tissue). For imaging analysis: Patient must have had at least 1 scan (either CT or MRI) within 28 days of starting treatment with systemic treatment for their cancer.

Exclusion Criteria

3. known or suspected active autoimmune diseases (congenital or acquired), such as interstitial pneumonia, uveitis, enteritis, hepatitis, pituitary inflammation, vasculitis, nephritis, thyroiditis, etc. Patients with type 1 diabetes with good insulin control can also be enrolled.

4. known allogeneic organ transplantation (except corneal transplantation) or allogeneic hematopoietic stem cell transplantation;

5. allergic to any component of monoclonal antibody;

6. suffering from other uncontrolled serious diseases, including but not limited to: A) severe infection in the active phase or clinically poorly controlled; B) HIV infection (HIV antibody positive); C) acute or chronic active hepatitis b (HBsAg positive and HBV DNA>1*103/ml) or acute or chronic active hepatitis c (HCV antibody positive and HCV RNA>15IU/ml); D) active tuberculosis, etc.;

7. class iii-iv congestive heart failure (New York heart association classification), poorly controlled and clinically significant arrhythmia;
