Renal cortical cell carcinoma is a cancer that starts in the outer part of the kidney, called the renal cortex. Most kidney cancers in adults begin here. The cancer grows from tiny tubes that filter blood and make urine. At first it may be small and silent. As it grows, it can press nearby tissues, spread into veins, and travel to other organs. It may also release hormones and chemicals that change blood pressure, blood counts, or calcium levels. Early finding by imaging gives the best chance for cure. Surgery is the main treatment when possible. Medicines can help when it has spread.
Renal cortical cell carcinoma is a kidney cancer that starts in the cortex, the outer part of the kidney where most filtering happens. Doctors usually call it renal cell carcinoma (RCC). The commonest type is clear-cell RCC; other types include papillary and chromophobe RCC. Small tumors may be found by accident on ultrasound or CT. Larger or aggressive tumors can cause blood in urine, flank pain, fever, weight loss, high blood pressure, or high calcium. Diagnosis and staging rely on contrast-enhanced CT/MRI and sometimes a needle biopsy. Treatment depends on size, spread, health of the patient, kidney function, and tumor biology. Core options are partial or radical nephrectomy, focal ablation for select small tumors, and systemic therapy with immunotherapy and targeted drugs for advanced disease. After surgery, some high-risk patients benefit from adjuvant pembrolizumab to reduce the chance of cancer coming back. Modern first-line treatment for advanced disease often combines an immune checkpoint inhibitor with a VEGF-targeted drug. Care plans follow international guidelines (AUA/EAU/ESMO/NCCN) and are personalized. AUAUrowebCloudFrontPubMed
Another names
Renal cortical cell carcinoma is most often called renal cell carcinoma (RCC). Other common names include kidney cancer (adult type), hypernephroma (older term), Grawitz tumor (historic), and renal parenchymal carcinoma. When a pathologist describes it more exactly, you may see names such as clear cell RCC, papillary RCC, chromophobe RCC, collecting duct carcinoma, medullary carcinoma (in sickle cell trait), MiT family translocation RCC (including TFE3/TFEB translocation), and multilocular cystic renal neoplasm of low malignant potential. Doctors sometimes say cortical renal carcinoma to stress that it arises from the kidney cortex. All of these sit under the broad umbrella of RCC.
Types
Clear cell RCC.
This is the most common type. Tumor cells look “clear” under the microscope because they contain fat and sugar. It often links to changes in a gene called VHL. Clear cell tumors can grow into veins and spread to the lungs or bones. Many modern targeted drugs and immunotherapies were tested first in this type.
Papillary RCC (Type 1 and Type 2).
These tumors grow in small finger-like shapes called papillae. Type 1 often relates to MET gene changes and tends to behave a little more gently. Type 2 is less common and can be more aggressive; a subset is tied to FH gene changes (HLRCC syndrome).
Chromophobe RCC.
Cells have pale, granular cytoplasm and special cell membranes. It often grows more slowly and has a better outlook than clear cell when found early. It may occur in patients with Birt-Hogg-Dubé syndrome.
Collecting duct (Bellini duct) carcinoma.
A rare and aggressive tumor that arises from the distal collecting ducts. It often presents late, with spread, and needs specialized care.
Renal medullary carcinoma.
A very rare, highly aggressive cancer seen almost only in people with sickle cell trait or disease. It tends to grow fast and needs urgent, expert treatment.
MiT family translocation RCC (TFE3/TFEB).
More common in children and young adults but also seen in adults. It carries special gene fusions and can vary in behavior.
Multilocular cystic renal neoplasm of low malignant potential.
This looks like a mass made of many cysts (fluid-filled sacs). It behaves in a very low-grade way and has an excellent outlook after surgery.
Sarcomatoid or rhabdoid features (patterns).
These are not separate types but patterns that can occur in any RCC subtype and make it more aggressive.
Unclassified RCC.
A small group of tumors that do not fit neatly into any category.
Causes
Cigarette smoking.
Tobacco chemicals enter the blood, reach the kidney, and damage DNA in the kidney tubule cells. This long-term injury increases cancer risk.Obesity.
Extra body fat changes hormones and growth signals (like insulin and IGF-1). It also causes low-grade inflammation. These effects can drive tumor growth in the kidney.High blood pressure (hypertension).
Chronic high pressure damages small kidney vessels and tubules. Some blood pressure drugs may be linked, but the strongest factor is the pressure itself.Chronic kidney disease.
Long-standing kidney scarring and inflammation make cells more likely to mutate and become cancer. The risk rises as kidney function drops.Acquired cystic kidney disease on dialysis.
Patients on long-term dialysis develop many kidney cysts. The cyst lining can turn into cancer after years of irritation and oxidative stress.Family history of RCC.
Having a close relative with RCC raises risk, showing that shared genes and environments matter.Von Hippel–Lindau (VHL) syndrome.
An inherited change in the VHL gene causes multiple clear cell tumors and cysts. Oxygen-sensing pathways go wrong and promote tumor blood vessels.Hereditary papillary RCC (MET gene).
An inherited change in MET leads to multiple papillary tumors. This gene pushes growth signals in kidney cells.Hereditary leiomyomatosis and RCC (FH gene).
A change in FH enzyme drives aggressive Type 2 papillary RCC with early spread in some patients.Birt–Hogg–Dubé (FLCN gene).
This syndrome causes skin bumps, lung cysts, and kidney tumors (often chromophobe or hybrid). The FLCN gene helps control cell growth.Tuberous sclerosis complex (TSC1/TSC2).
mTOR pathway changes promote cysts and tumors in many organs, including kidneys.Sickle cell trait/disease.
It is strongly tied to renal medullary carcinoma because repeated low-oxygen stress injures medullary cells.Workplace solvents (trichloroethylene).
This degreasing chemical and certain metals like cadmium can harm kidney DNA and raise RCC risk after long exposure.Long-term phenacetin or heavy analgesic misuse (historic).
Old pain pills (now rarely used) harmed kidney tissue and increased cancer risk.Male sex.
Men develop RCC more often, likely from hormone and exposure differences.Older age.
Risk rises after age 50 because DNA damage accumulates and repair slows.Diabetes mellitus.
High sugar and insulin levels change growth signals and increase oxidative stress in kidneys.Kidney transplant with immunosuppression.
Long-term immune suppression reduces the body’s cancer surveillance, increasing several cancer risks, including RCC.Hepatitis C infection.
Some studies show a higher RCC risk, possibly from chronic inflammation and metabolic effects.Radiation to the abdomen (past).
Old radiation exposures can damage DNA in kidney tissue and raise risk years later.
Symptoms
Blood in urine (hematuria).
Urine may look pink, red, or cola-colored. It can come and go. It happens when the tumor bleeds into the collecting system.Flank or side pain.
A dull ache under the ribs or in the back may occur if the tumor stretches the kidney capsule or blocks urine flow.A lump in the abdomen or flank.
Sometimes a firm mass can be felt if the tumor is large or near the surface.Unexplained weight loss.
Cancer cells use energy and release substances that reduce appetite and cause the body to burn muscle and fat.Fever and night sweats.
Inflammatory chemicals from the tumor can reset the body’s thermostat and cause sweats without infection.Tiredness (fatigue).
Anemia, inflammation, and poor sleep from pain combine to make the person feel very tired.Anemia (low red cells).
Bleeding and inflammation lower red blood cell production. The person feels weak and short of breath with activity.Polycythemia (too many red cells).
Some tumors release extra EPO hormone, making the blood thicker. The person may have headaches or a ruddy face.High blood pressure.
Tumors may disturb kidney blood flow and renin signals, raising blood pressure or making it harder to control.High calcium (hypercalcemia).
Tumors can raise calcium by releasing PTH-like substances or from bone spread. This can cause thirst, confusion, and constipation.Left-sided varicocele.
Swollen scrotal veins on the left may appear if the tumor blocks the left renal vein.Leg swelling.
A large mass or vein clot can slow blood return from the legs and cause edema.Persistent cough or chest pain.
If cancer spreads to the lungs or chest lymph nodes, cough, pain, or breathlessness may appear.Bone pain or fractures.
Bone spread weakens the skeleton, causing deep pain or breaks after minor injury.Liver-related symptoms without liver metastasis (Stauffer syndrome).
Some people show abnormal liver tests, itching, or jaundice-like symptoms due to immune effects from the tumor, even with a normal liver scan.
Diagnostic tests
A) Physical Examination
General inspection and vital signs.
The doctor checks weight, temperature, pulse, and blood pressure. Weight loss, fever, or hard-to-control hypertension may point toward kidney cancer or its paraneoplastic effects.Abdominal palpation with bimanual ballottement.
Using both hands, the clinician gently traps and moves the kidney between the hands. A large, firm, non-tender mass in the flank can be felt, especially in thin patients.Costovertebral angle (CVA) percussion.
A gentle fist tap over the back where the kidney sits may cause tenderness if there is bleeding, blockage, or infection around a tumor.Scrotal examination for varicocele.
A new, persistent left-sided varicocele that does not empty when lying down may suggest blockage of the left renal vein by a mass or clot.
B) Manual/Bedside Tests
Bedside urine dipstick for blood.
A simple strip test detects blood or protein in urine. It is quick and cheap. A positive test does not prove cancer but prompts full urinalysis and imaging.Three-glass urine collection (localization test).
Collecting urine in three cups at the start, middle, and end of urination may help suggest where bleeding comes from (urethra, bladder, or upper tract), guiding further tests.Auscultation for abdominal bruits.
Listening with a stethoscope for whooshing sounds over the upper abdomen can hint at renal artery narrowing or high-flow vessels around a tumor.
C) Laboratory & Pathological Tests
Complete blood count (CBC).
Looks for anemia from bleeding or inflammation, or high red cells from extra EPO. Platelet counts may be high as a paraneoplastic effect.Serum creatinine and estimated GFR.
Shows how well the kidneys filter blood. It guides safe imaging contrast use and helps plan surgery (partial vs total nephrectomy).Electrolytes, calcium, liver tests, and alkaline phosphatase.
High calcium suggests paraneoplastic effects or bone spread. Abnormal liver tests may be from Stauffer syndrome or metastasis. High alkaline phosphatase can point to bone activity.Lactate dehydrogenase (LDH) and inflammatory markers (ESR/CRP).
These can be elevated in advanced disease and sometimes enter risk scores used to predict outlook.Urinalysis with microscopy and urine cytology.
Microscopy confirms red cells and looks for protein or casts. Urine cytology searches for malignant cells, mainly to rule out urothelial carcinoma when hematuria is present.Coagulation profile (PT/INR, aPTT).
Important before biopsy or surgery and can detect clotting changes that sometimes accompany cancer.Percutaneous core needle biopsy with histology and immunohistochemistry (when needed).
Not always required if imaging is classic and surgery is planned, but very useful when diagnosis is uncertain or systemic therapy is planned. It confirms the subtype and can include molecular tests (e.g., VHL, PBRM1, BAP1 in clear cell; MET in papillary; FH in HLRCC; FLCN in Birt–Hogg–Dubé).
D) Electrodiagnostic Tests
12-lead electrocardiogram (ECG).
This does not diagnose the tumor, but it checks heart rhythm and prior damage. It is important before anesthesia and for monitoring heart safety with targeted drugs or immunotherapy.Holter monitor (ambulatory ECG) when indicated.
If the patient has palpitations, dizziness, or is starting a medicine with possible rhythm effects, a 24–48-hour ECG can detect silent arrhythmias and guide therapy safely.
E) Imaging Tests
Renal ultrasound, often with Doppler.
First-line in many settings. It shows if a mass is solid or cystic and can assess blood flow. It is fast, painless, and uses no radiation. It helps triage to CT or MRI.Multiphase contrast-enhanced CT (renal mass protocol).
The key test for most adults. It takes pictures before and after contrast in arterial, venous, and delayed phases. It defines tumor size, enhancement, vein invasion, lymph nodes, and nearby organ contact. It also helps distinguish benign lesions, like angiomyolipoma or complicated cysts.MRI abdomen with and without gadolinium.
Used if iodine contrast is not safe or to better see tumor thrombus inside the renal vein or inferior vena cava. It provides excellent soft-tissue contrast and vascular detail.Chest CT for staging (± bone scan or PET-CT when symptoms).
Chest CT looks for lung nodules and chest lymph nodes because lungs are a common spread site. Bone scan or PET-CT is added when bone pain, high alkaline phosphatase, or other signs suggest bone or widespread disease.

(Avoid grapefruit/Seville orange, St. John’s wort, and high-dose turmeric/green tea extracts due to CYP3A4/P-gp interactions with many TKIs.) PubMed
Supportive “Immunity/Regenerative/Stem-Cell–Related” Drugs
(These are not anti-cancer drugs for RCC; they support blood counts or bones and are used only when clinically indicated.)
Filgrastim (G-CSF). Dose: typical 5 µg/kg SC daily during neutropenia. Function: shortens neutropenia. Mechanism: stimulates neutrophil production.
Pegfilgrastim. Dose: single 6 mg SC per chemo cycle (when used). Function: long-acting neutrophil support. Mechanism: pegylated G-CSF.
Epoetin alfa (ESA). Dose: per label; start only for symptomatic chemo-related anemia after iron assessment. Function: improve Hb and reduce transfusion. Mechanism: stimulates red cell production.

Radical nephrectomy. Procedure: removes the entire kidney (± adrenal, nodes when indicated), usually minimally invasive. Why: for large or complex tumors not suitable for partial nephrectomy. Uroweb
Cytoreductive nephrectomy. Procedure: remove primary tumor in metastatic disease. Why: Not routine in the IO/TKI era; may be considered selectively (good performance, limited metastases) often after systemic therapy (deferred CN). CARMENA/SURTIME shaped this approach. New England Journal of MedicinePubMed+1UroToday
Thermal ablation (cryoablation/RFA). Procedure: needle probes freeze or heat small tumors (often <3–4 cm), usually percutaneous with CT/US guidance. Why: for select patients unfit for surgery or with small masses. AUANewsPubMed
Renal artery embolization (palliative or pre-op). Procedure: catheter blocks blood flow to tumor to reduce bleeding or pain. Why: symptom control or to assist surgery in selected cases. (Guideline-listed option.) PubMed
Prevention & Risk-Reduction Tips
Do not smoke; get help quitting. 2) Keep a healthy weight and waist size. 3) Exercise regularly. 4) Control blood pressure and diabetes. 5) Use caution with long-term, high-dose painkillers; discuss safer plans. 6) Reduce harmful chemical exposures at work; follow safety protocols. 7) Treat chronic kidney disease risks early. 8) If strong family history or early-onset RCC, seek genetic counseling. 9) Limit alcohol; prioritize sleep. 10) Stay current on vaccines and routine health checks. PubMed
When to see doctors urgently or promptly

Limit/avoid: (8) Grapefruit/Seville orange and St. John’s wort (dangerous interactions with many TKIs); (9) Excess salt (worsens BP); (10) High-risk raw foods if your team advises food-safety precautions; (11) Heavy alcohol; (12) Mega-dose supplements without lab-proven need. PubMed
Frequently Asked Questions
Is “renal cortical cell carcinoma” the same as RCC?
Yes—most kidney cancers start in the cortex; “RCC” is the standard name.Will every small mass need surgery?
Not always. For some small, slow-growing masses, active surveillance is reasonable; many others get partial nephrectomy. PubMedWhat is the best first-line treatment for advanced RCC?
Often a combo: PD-1 immunotherapy plus a VEGF-TKI (e.g., pembrolizumab+axitinib, nivolumab+cabozantinib, lenvatinib+pembrolizumab) or dual IO (nivolumab+ipilimumab), chosen by risk and comorbidities. New England Journal of Medicine+2New England Journal of Medicine+2Do I need adjuvant therapy after surgery?
If you have intermediate-high or high-risk features, adjuvant pembrolizumab is a standard option that improves outcomes. Keytruda HCPUroTodayAre there pills for RCC?
Yes—targeted TKIs (axitinib, cabozantinib, lenvatinib, sunitinib, pazopanib, tivozanib) and belzutifan (HIF-2α inhibitor). Many are used with immunotherapy. PubMedU.S. Food and Drug AdministrationWhat about mTOR inhibitors?
Everolimus and temsirolimus help after earlier treatments or in certain risk groups. New England Journal of MedicineIs cytoreductive nephrectomy still done in stage 4?
Sometimes, selectively, often after systemic therapy, not routinely upfront. New England Journal of MedicinePubMedHow are side effects handled?
Teams monitor blood pressure, labs, thyroid, liver, and skin; they use dose changes, supportive meds, and brief treatment holds per guidelines. PubMedCan diet or supplements cure RCC?
No. Nutrition can support strength and help side effects, but it does not replace surgery/medicines. Always check for drug–supplement interactions. PubMedWhat is belzutifan and when is it used?
It’s a HIF-2α inhibitor used after prior PD-(L)1 and VEGF-TKI; it targets a core ccRCC pathway. U.S. Food and Drug AdministrationHow long will I be on treatment?
Varies—some combos are given for up to 2 years for the IO part, with TKI continued while effective/tolerated. Your team individualizes this per response and side effects. (Guideline-based practice.) PubMedWhat scans do I need for follow-up?
Schedule depends on stage and treatment; typically CT chest/abdomen/pelvis at regular intervals early, then less often over time. PubMedCan I keep my kidney function?
Partial nephrectomy preserves more kidney tissue when feasible; strict BP, diabetes, and hydration control also protect function. UrowebAre results improving?
Yes. Multiple modern combinations show better survival than older standards, with durable responses in a subset of patients. New England Journal of Medicine+2New England Journal of Medicine+2Where can I find the latest, trustworthy guidance?
International guidelines from ESMO/EAU/AUA/NCCN and updates from ASCO present the latest standard-of-care recommendations. PubMedCloudFrontAUA
