At present, aggressive surgical approach in combination with perioperative chemotherapy allows to extend indications for surgical intervention in patients with metastatic colorectal cancer, since only a radical liver resection provides better long-term survival. Contrast enhancement imaging techniques are important before considering treatment options to identify patients with resectable and potentially resectableliver metastases. Our study evaluated the qualitative and quantitative parameters of thedynamic enhancement pattern of liver metastases. This review will be analyzed the results of liver contrast-enhanced ultrasound studies in 104 patients with secondary colorectal liver metastases before primary tumor resection, as well as the monitoring of systemic chemotherapy and post-ablation follow-up to access treatment respond.
alignant tumors of reproductive system are the most incident cancers in women (more than 35% in total). Because of its validity, non-invasiveness, safety, accessibility, repeatability, and relative simplicity nowadays ultrasonography is one of the leading diagnostic methods in gynecologic oncology. However, despite high resolving power of this method, the frequency of errors in topical diagnosis of pelvic lesions, their characterization, and degree of tumor spread assessment remains around 10-30%.Purpose. To identify and analyze causes of errors in ultrasound diagnosis in gynecologic oncology.Materials and methods. We analyzed pre-operative ultrasound protocols from 1167 women with cervical cancer, endometrial cancer, and ovarian cancer who were getting treatment at our facility. Ultrasound results were compared with intraoperative data and pathology results.Results. We analyzed causes of 68 subjective and objective errors in assessing local and distant spread of the tumor. Objective errors were predominantly associated with the limit of the scanner resolving power and the subjective ones were related to the ultrasound exam technique and incorrect interpretation of the results by a specialist.
Conclusion.Incorrect interpretation of ultrasound data associated with subjective causes results in incomplete, partially wrong or wrong diagnosis. Frequency of objective errors can be decreased with proper equipping of ultrasound departments while frequency of subjective errors can be decreased with proper ultrasound exam technique.
АктуальностьНесмотря на успешное лечение и проводимую раннюю диагностику, рак почки занимает второе место среди новообразований мочеполовой системы с тенденцией к росту заболеваемости. Сегодня мы располагаем современными и качественными методами лучевой и функциональной диагностики. Сюда входят компьютерная томография (КТ), магнитно-резонансная томография (МРТ), позитронно-эмиссионная компьютерная томография (ПЭТ-КТ), ультразвуковое исследование (УЗИ) [1,2].Возможности ультразвуковой диагностики не стоят на месте. В настоящее время контрастные препараты стали внедряться и использоваться в УЗ-диагностике. Это был большой прорыв в качестве как ранней диагностики, так и в контроле после проведенного лечения. Преимуществом в лечении остается за хирургическим вмешательством, но объем и тактика этого вмешательства будут напрямую зависеть от полученных диагностических данных. Чаще всего раком почки страдают люди в возрасте от 60 до 75 лет. Как правило, основная масса этих
