Kidney cancer is really a malignant tumour developed from the kidney cells. Malignant kidney tumours account for 2-5% of malignant cancers in adults. Men are impacted twice as frequently as ladies. The cause of kidney cancer is unknown, however, some genetic elements & damages of the kidney cell DNA brought on by e.g. cigarette smoking, mutagens or environmental factors are taken into consideration. It’s usually diagnosed in people over the age of 45, nevertheless, recently, the reduction from the age limit of people who are diagnosed with kidney cancer have been observed, which is affected by the growth of influence from the environmental carcinogenic factors, as well as the spread & constant improvement of diagnosing possibilities. Cancers constitute 85% of kidney tumours. There are several types of kidney cancer. Probably the most common type is really a renal cell cancer. Kidney cancer is very dangerous mainly due to the fact that its signs occur in a late stage. It can cause the late detection from the tumour change – frequently in an advanced developing stage. Kidney cancer often develops in a tricky way with out causing any disturbing signs. Early detection and correct diagnosis from the ill individual need performing some or all of the types of examination mentioned below. Diagnostic tests which allow to make a diagnosis include: urine check, blood test (morphology, concentration of urea’s creatinine), & imaging tests: ultrasound scan of the abdomen, computed tomography scan, alternatively urography (x-ray examination of the ureters after injecting intravenous dye), renal arteriography (the blood vessels examination using dye). Magnetic resonance imaging is sometimes used. A kidney biopsy, that’s removing cells from the tumour & examining beneath a microscope regardless of whether the tumour contains the tumour cells isn’t usually performed. Currently, more than 80% of kidney cancers are detected incidentally, usually because of an ultrasound scan carried out as a standard procedure or due to other ailments. Therefore, superior cancers of kidney parenchyma rarely happen (they constitute >15%).

Kidney cancer treatment

Surgery is a standard treatment for kidney cancer. It is aim is to surgically eliminate the tumour, generally along with the kidney and lymph nodes containing the tumour, and, if feasible, surgically remove single metastases if they occur. A chance of cure (6-year survival rate with out the presence of metastases is considered a recovery criterion) depends on the stage of the illness (the tumour’s size, infiltration of the surrounding tissues, metastases to other organs), and accounts for up to 75%. Nevertheless, in extremely advanced stages, it is much lower. The presence of impossible to eliminate metastases worsens prognosis to a big extent. Used in the therapy of other cancers  -  chemotherapy and radiotherapy – aren’t extremely efficient in treating kidney cancer. Better effects are achieved by using immuno or chemoimmunotherapy. However, they’re efficient only in some patients.

Chemoimmunotherapy consists in administering recombinant cytokine together with chemotherapeutic agent (so called the Hanover schedule). The attempts of using tumour infiltrating leukocytes or vaccines in the tumour cells are also made. The effectiveness of these techniques in treating advanced forms of kidney cancer is estimated at dozen or so per cent, however, they are still under clinical research.

Side effects that may occur when using some of the chemoimmunotherapy trials.

The side effects mentioned below don’t include all the possible complications. Chemoimmunotherapy ought to be performed in medical centres experienced in conducting such treatment.

Side effects list:

Capillary leak syndrom

Hypotony occuring due to the capillary leak syndrom and appearing within few hours after treatment’s beginning can recede spontaneously. Some sufferers can need careful intravenous administration of fluids and albumins, and, in persistent cases, small doses of dopamine. When administering fluids intravenously, it is important to keep in mind that the danger of lungs swelling is higher in patients with capillary leak syndrom when filling the vascular tissue. Prior to performing chemoimmunotherapy, all serum exudations ought to be cured (especially those concerning organs essential to living, e.g. liquid in pericardium), because due towards the capillary leak syndrome they can intensify when administering a drug.

Kidneys’ functional activity

In all patients, it’s important to monitor parameters of the ionic and acid-alkaline balance because of to the chance of occurring renal failure with oliguria.

Respiratory system

Throughout treatment it’s important to monitor the practical activity from the respiratory program, particularly in patients who in physical examination are diagnosed with the improve in respiration frequency or auscultation changes over lung fields. In some patients, in case of respiratory failure, it could be necessary to use forced respiration for some time.

Central nervous system

Negative effects from the central nervous program (anxiety, confusion, depression), though reversible, can remain for several days after discontinuing therapy. Chemoimmunotherapy can intensify the signs related towards the undiagnosed focuses of metastases in the central nervous system. If drowsiness occurs, the therapy ought to be discontinued. Further drug administration can lead to coma.

Digestive system

In situation of gastric-intenstine symptoms, antiemetic or antidiarrhoeal medicines are administered if necessary.

Skin

In patients who’re diagnosed with pores and skin carcinomas with pruritus, administering antihistamine medicines brings relief.

Autoimmunological diseases

It is common knowledge that some of the administered drugs can intensify the coexisting immunological disease and complications threatening life (in some patients with Crohn’s disease therapy caused exacerbation of the disease requiring surgical intervention), nevertheless, not in all sufferers who suffered from such complications immunological disorders had previously been diagnosed. Therefore, it is recommended to strictly monitor treated sufferers, taking into consideration irregularities within the thyroid’s function and other feasible immunological issues.

Infection risk

Using chemoimmunotherapy can trigger higher susceptibility to bacterial infections. That’s why, before administering drugs, all of the infection focuses ought to be cured, & patients with catheters placed to the central veins should be prophylactically administered with antibiotics.

Pregnancy & breast-feeding

It is suggested for chemoimmunotherapy not to be used in persons of reproductive age who don’t use the approved contraceptive methods, in pregnant or breast-feeding women.

Driving & operating machines

As a result, in sufferers after surgeries these parameters are monitored. Throughout the postoperative period, the body temperature and also the amount of excreted urine are also measured.

Throughout the convalescence after the surgery, the affected person should sit & stand up as soon as possible. It is important to avoid the possible complications caused by the respiratory program, as well as the danger of creating vein thromboses. If there are no surgical contraindications, the patient ought to sit around the second day following the surgical procedure. In some sufferers, breathing exercises are additionally applied. In recumbent sufferers, there’s a high danger of creating thromboses in veins. Especially in people with varicose veins. This kind of sufferers, prior to sitting or standing attempts,  should move their legs in the recumbent position as much as they can in order to improve blood circulation.

In some individuals following surgeries, so called keloids (i.e.lesions developing within the scar area) might be formed. Following several weeks (5-9) from the surgical procedure, when the skin is accurately healed, the ointment preventing the formation of unsightly changes may be utilized.

Following discharging in the hospital, the patient should call for the histopathological examination outcomes. Usually, this kind of results are available after 2-4 weeks from discharging in the hospital.

All patients after surgical procedures receive scheduled dates of check-ups in hospital clinics.

Generally after removing the tumour using the kidney, the diet with smaller amount of protein (reducing meat, cured meat, & cheese consumption) & drinking higher amount of fluids are advised. The range of physical activity depends on the patient’s efficiency.
