Currently, open radical nephrectomy is mainly performed in patients with large tumor size, locally advanced tumors and tumor thrombus extending into the vena cava. Nephron sparing surgery (NSS) is the most commonly performed procedure with excellent local cancer control in small, resectable renal tumors. Increasingly, laparoscopy is being performed and now recommended for early-stage RCCs unsuitable for NSS. Laparoscopic radical nephrectomy seems to be providing long-term cancer control comparable to open radical nephrectomy. Laparoscopic NSS is now available particularly in patients with a relatively small and peripheral renal tumor. The current therapy for metastatic RCC is inadequate and surgery is an important component of the treatment with combined immunotherapy in which response rates remain at about 15% to 25%. </span><span style="font-style: normal; color: black;">In the past several years, significant advances in the underlying biological mechanisms of RCC development have permitted the design of new molecularly targeted therapeutics </span><span style="font-style: normal; color: black;">such as antibodies, tumor vaccines, anti-angiogenesis agents and small molecule tyrosine kinase inhibitors in order to improve treatment options.<strong style="mso-bidi-font-weight: normal;"></strong></span></span></span></p><p class="MsoBodyText" style="margin: 0cm 0cm 0pt; line-height: normal; text-align: left;" align="left"><span style="font-size: small;"><span style="font-family: Times New Roman;"><strong style="mso-bidi-font-weight: normal;"><span style="font-style: normal;">Conclusion: </span></strong><span style="font-style: normal;">Surgery is the only curative treatment for localized RCC and NSS cures most of the patients with early-stage disease.
