To plan therapies for Hepatocellular Carcinoma (HCC), staging methods are necessary. The most often employed HCC management recommendation is the Barcelona Clinic Liver Cancer (BCLC) staging system. Transarterial Chemoembolisation (TACE) is the go- to therapy for BCLC stage B (intermediate HCC). Numerous studies back the use of TACE in individuals with early and advanced HCC. TACE may be an option for individuals who are not candidates for Radiofrequency Ablation (RFA) or Hepatic Resection (HR) for BCLC stage 0 (very early HCC). TACE with RFA offers superior local tumour suppression than RFA alone in BCLC stage. Patients awaiting liver transplants may benefit from TACE as a bridging treatment. When compared to supportive care approaches, TACE improves survival for BCLC-B patients. Patients with BCLC-C stage HCC are treated in the first instance with sorafenib. The combination of sorafenib and TACE has demonstrated efficacy in slowing the development of tumours. Patients with HCC and portal venous thrombosis have superior survival results with TACE combined with radiation. Taking all of these facts into account, it is obvious that TACE, either alone or in conjunction with other therapies, plays a crucial part in the treatment of HCC at every stage. Patients with HCC should get a variety of treatments, and the best TACE candidates should be chosen using a more accurate patient classification approach.

Image segmentation is the process to capture the object from the background and it is a difficult task when a vision of the object is in stochastic region. Here introduce in this paper extension of stochastic random walker segmentation method. In stochastic random walker segmentation, a weighted graph is built from the image, where the each pixel considered as a node and edge weights depend on the image gradient between the pixels. For given seed regions, the probability are evaluated for a stochastic random walk on this graph starting at a pixel to end in one of the seed regions. The problem associated with existing method is the number of random variable (gray-level value in random order) in stochastic images. These random variables increase the graph sizes of stochastic images. If the graph size will increase, consequently execution time would also increase. To overcome these problems, the proposed "Improved stochastic random walker segmentation based on Gaussian filtering" for stochastic image segmentation. In proposed method Gaussian filter has been used for the removal of uncertain gray level and which in turn reduce the noise level and the resultant graph size of corresponding stochastic image, then apply stochastic random walker segmentation method which may help to decrease the execution time of the segmentation process.
