Complete Response Using Sorafenib Monotherapy for Advanced Hepatocellular Carcinoma with Multiple Lymph Node and Bone Metastases: A Case Report

Hepatocellular carcinoma（HCC）is the sixth most commonly diagnosed cancer worldwide. Sorafenib is an oral multikinase inhibitor used in the palliative treatment of advanced HCC. However, there were no reported cases of complete response（CR）from two previous large phaseⅢ clinical trials. Here, we report a case of CR in a patient with advanced HCC with multiple lymph node and bone metastases, treated with sorafenib monotherapy for 8 months. To our knowledge, this is the first evidence showing CR following sorafenib monotherapy for HCC with bone metastasis

Raman spectroscopic evaluation of human serum using metal plate and 785- and 1064-nm excitation lasers.

In this study, we utilized a stainless steel (SUS304) plate for measuring the Raman scattering spectra of body fluid samples. Using this stainless steel plate, we recorded the Raman scattering spectra of 99.5% ethanol and human serum samples by performing irradiation with 785- and 1064-nm lasers. Raman scattering spectra with intensities equal to or greater than those reported previously were obtained. In addition, the Raman scattering spectra acquired using the 1064-nm laser were less influenced by autofluorescence than those obtained via use of the shorter-wavelength laser. Moreover, the shapes of the spectra did not show any dependence on integration time, and denaturation of the samples was minimal. Our method, based on 1064-nm laser and the stainless steel plate, provides performance equal to or better than the methods reported thus far for the measurement of Raman scattering spectra from liquid samples. This method can be employed to rapidly evaluate the components of serum in liquid form without using surface-enhanced Raman scattering
