Abstract

High-frequency ultrasonography has become an important diagnostic tool in dermatovenerology. It is used for assessment of the cutaneous layers in diverse benign and malignant skin lesions and diseases. Herein we present the practical value of preoperative measurement of cutaneous melanoma thickness, the explanation of the possible reasons for different sonographic and histologic Breslow thickness, and the practical importance of high-frequency 20 MHz ultrasonography in preoperative measurements of cutaneous melanoma thickness. Fifty patients (31 women aged 41.6±15.4 years, 19 males aged 54.5±11.4 year (mean ± Standard Deviation) were examined in the Skin Cancer Clinic from January 2014 to December 2015. Suspected cutaneous melanomas were investigated with skin ultrasound Dermascan C (Cortex Technology, Denmark) before surgical removal. The Breslow thickness of cutaneous melanomas was analyzed by precise pathological examination after extirpation. Statistical analysis revealed a significant positive correlation between ultrasonographic melanoma thickness and Breslow thickness (r=0.92, P<0.001). The mean thickness of invasive tumors evaluated by high frequency ultrasonography was 6.77 % higher compared with the mean Breslow thick...Continue Reading

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
