Everything you need to know about kidney cancer

Renal cell carcinoma (RCC) is caused by a abnormal growth of tumor cells in the kidney. CRC is the most common solid renal lesion and represents approximately 90% of renal malignant tumors.

There are different histological subtypes, the three main ones being clear cell renal cell carcinoma (80-90%), the papillary renal cell carcinoma (10-15%) and finally the renal chromophobe cell carcinoma (4-5%).

The proportion is higher in men than in women (1.5:1), with a higher incidence in the older population.

CRC does not produce symptoms in the initial stages of the disease, in fact, in most cases its diagnosis is incidental after performing an imaging test for another reason.

However when the CRC is in advanced stages It can cause symptoms such as low back pain, hematuria (presence of blood in the urine), palpable mass in the abdomen or affectation of general condition (fatigue, loss of appetite, etc.)

Some have been described risk factors that increase the probability of suffering from CRC. The main ones are obesity, smoking, hypertension and some medications.

On the other hand, they have been described genetic or hereditary risk factors that significantly increase the likelihood of developing a kidney tumor. Among them are von Hippel-Lindau disease, Birt-Hogg-Dube syndrome, hereditary papillary CRC or Cowden syndrome among others. For this reason, people who carry a genetic mutation or suffer from a disease mentioned above must be closely monitored to early detect tumors that may appear.

Kidney tumors are diagnosed through imaging tests such as abdominal ultrasound and CT. The study must be completed with a blood and urine analysis, but it is also essential to perform a correct anamnesis and a physical examination. Early detection of kidney cancer is essential to achieve a high degree of cure after treatment.

Treatment of malignant kidney tumors depends on the size, extent and location of the tumor within the kidney.. In addition, the function of the contralateral kidney, the general condition of the patient, his age and the presence of other diseases are taken into account.

The main treatments for kidney cancer in localized stage are radical nephrectomy (consists of removing the entire kidney) or partial nephrectomy (it consists of removing only the part of the kidney where the tumor is, in this way a large part of the kidney is preserved). These surgical interventions can be performed using two approaches, both laparoscopic and da Vinci robot-assisted laparoscopic.

The latter is especially useful in partial nephrectomy since helps to perform a better repair of the kidney defect that remains after removal of the tumor and therefore reduces the risk of complications.

Renal cell carcinoma (RCC) is the most common solid tumor in the kidney. It is the 90% of all malignant kidney tumors.
