Possibilities of contrast-enhanced ultrasound tomography in the diagnosis of metastatic liver lesions in patients with cervical cancer

Abstract

Therapy for the progression of malignant tumors is one of the most urgent problems of modern
oncology. Features of relapse and metastasis of malignant neoplasms determine the clinical course
of the disease, its prognosis, and treatment tactics for this category of patients. The effectiveness
of treatment largely depends on the timeliness and quality of diagnosis.
With the progression of cervical cancer (CC), there are several ways to spread the tumor,
depending on the type of its growth. With exophytic forms of cervical cancer, metastases in the
vagina are more often diagnosed, with endophytic and mixed forms - in the uterine body or vaginal
stump after surgical treatment, which characterizes the local spread of the tumor. Regional spread
is characterized by metastasisof m to retroperitoneal (pelvic andlumbar) lymph nodes, which is an
unfavorable prognostic factor. Hematogenous metastases in cervical cancer are rarely diagnosed;
they are localized in the lungs, liver, and bones
