background beta catenin plays a key role in cancer tumorigenesis. however, its prognostic significance in patients with colorectal cancer (crc) remains controversial. it has been demonstrated that 90% of all tumors have a mutation in individual components of multiple oncogenes in wnt/β-catenin pathway. accumulation of nuclear β-catenin in cytoplasm leads to uncontrolled cell proliferation. thus...

Leiomyosarcoma is a rare neoplasm with poor survival rate. Between June 2018 to January 2019 we treated case of Prostate initially metastatic the lung and liver multiple pelviclymph nodes. Five cycles chemotherapy palliative radiotherapy have been delivered mean follow up 1 year .Chestabdominal-pelvic CT scan MRI bone are necessarily assess clinical staging. The objective this study review our ...

This paper represents an overview of the uses of ultrasound in tumor detection and staging. This modality can detect and define the etiology of a mass and is helpful in staging the neoplasm and in streamlining the diagnostic and/or staging workup. Often a mass can be localized and biopsied or aspirated, leading to prompt diagnosis and treatment. In addition, ultrasound may be used in following ...

Esthesioneuroblastoma (ENB) is a malignant neoplasm of the olfactory epithelium. Metastasis of ENBs to retropharyngeal lymph nodes is an important finding on imaging examinations that alters staging and treatment. A total of 17 cases of ENB from 3 institutions were evaluated. The CT and MR imaging findings from the cases of 4 patients with ENB with retropharyngeal metastatic disease are reviewe...

The presence of soft tissue edema around a malignant musculoskeletal neoplasm can interfere with accurate local tumor staging at magnetic resonance imaging. This article discusses and illustrates such edema, emphasizing means for avoiding misinterpretation of edema and subsequent overstaging.

Primary hepatocellular carcinoma (HCC) is a significant tumor worldwide and represents the most common primary hepatic neoplasm. Staging criteria are important for appreciation of timely work up of these neoplasms in contradiction with surgical colleagues. This article demonstrates the appearance of HCC on multiphasic, multidetector CT (MDCT) and relates these findings to current staging criter...

BACKGROUND: The identification of all sites of intra-abdominal adenocarcinoma is key to optimal surgical resection and tumor staging. Conventional imaging methods and direct visualization and palpation have limited sensitivity and specificity. Radioimmunoguided surgery (RIGS) has a potential to improve these parameters. METHODS: The development of the RIGS concept is presented, and the studies ...

Melanoma is the most common lethal cutaneous neoplasm. In order to harmonise treatment and follow-up of melanoma patients, guidelines for the management of melanoma in Switzerland were inaugurated in 2001 and revised in 2006. A new classification and recent results in randomised trials necessitated changes concerning staging and modifications of the recommendations of therapy and follow-up.
