Renal cell carcinoma (RCC) occupies one of the leading places in the world for morbidity among malignant neoplasms of the genitourinary system. The frequency of occurrence of bilateral RCC according to different authors is 2–6% of the total population of patients with RCC. Currently, the only effective method of treatment of bilateral RCC is surgical treatment. Patients with bilateral RCC are at high risk of dev eloping of local recurrence or progression of the disease after organ-preserving surgeries, which is why the surgeon is faced with a choice between a high risk of developing renal failure or relapse and/or progression of the disease, depending on the extent of the surgical intervention. According to the literature, in patients with bilateral RCC there was an increase in the incidence of papillary variant of RCC up to 19% and the presence of multifocal lesion. Surgical treatment of bilateral RCC is the only effective method to achieve satisfactory oncological results at a low incidence of complications. The m ost justified option for the treatment of bilateral RCC is the implementation of bilateral organ-preserving treatment, which allows achieving the optimal functional results. This article presents a clinical case of successful surgical treatment of a patient with bilateral RCC with multiple tumors.
Over the last 10 years, the capacities of second-line systemic therapy for metastatic renal cell carcinoma (mRCC) changed significantly. Targeted therapy is a standard treatment for patients with mRCC. However, the choice of therapeutic agents for such patients remains challenging. In the absence of reliable prognostic biomarkers, physicians can use only the results of randomized clinical trials and their own routine experience with targeted drugs when choosing a regimen of second-line therapy. The article discusses the current situation with second-line therapy with the three new options available for patients with mRCC. It also contains a case report, describing our successful experience of treatment a female patient that received 6 variants of chemotherapy with good effect during 89 months after the diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
