Evaluation of the growth pattern of carcinoma of colon and rectum by MDCT.

ConclusionThe tumor growth doubling time of colorectal cancer has a very broad aspect. The initial wall thickness of the tumor on MDCT appears to be the most powerful parameter showing correlation with the volume growth rate. PMID: 23436826 [PubMed - as supplied by publisher]

MALAT1 inhibits the Wnt/β-catenin signaling pathway in colon cancer cells and affects cell proliferation and apoptosis. Bosn J Basic Med Sci. 2019 Nov 15;: Authors: Zhang J, Li Q, Xue B, He R Abstract Metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is a highly conserved long noncoding RNA, which has been related to various pathological processes, including cancer. The role and mechanism of MALAT1 in colon cancer are not clear. We investigated MALAT1 expression in colon cancer tissues, the effect of MALAT1 on proliferation and apoptosis of SW480 cells, and the signaling pathway invo...

In conclusion, Acacetin induces mitochondrial ROS-mediated cell death in a caspase-independent manner in SW480 and HCT-116 colon carcinoma cells by inducing apoptosis inducing factor (AIF), which may potentiate its anticancer and chemotherapeutic prospects against colorectal carcinoma.

This study aimed to compare and analyze the patterns of care and survival outcomes of patients with anal squamous cell carcinoma and anal adenocarcinoma. DESIGN: This was a retrospective study. SETTING: This study was performed by utilizing the National Cancer Database. PATIENTS: We selected a total of 19,539 patients between 2004 and 2014 with stage II to III squamous cell carcinoma or adenocarcinoma of the anus. INTERVENTION: The treatment groups analyzed were surgery alone, neoadjuvant chemoradiation followed by surgery, surgery followed by adjuvant chemoradiation, or definitive chemoradiation. MAIN OUTCOME...

SUMMARY: The use of transoral sonography–guided fine-needle aspiration for intraoperative localization of retropharyngeal masses has been described by Fornage et al. The purpose of this study was to assess the accuracy of this technique. We reviewed the images and medical records of 26 patients with a retropharyngeal lesion suspicious for a metastatic lymph node of Rouviere identified on CT and/or PET/CT. There were 14 patients with a history of thyroid cancer, 7 with mucosal squamous cell carcinoma, 1 with renal cell carcinoma, 1 with parotid acinic cell cancer, 1 with metastatic colon adenocarcinoma, and 2 with no ...

Publication date: Available online 16 October 2019Source: Life SciencesAuthor(s): Ahmed Hammad, Zhao-Hong Zheng, Yang Gao, Akhileshwar Namani, Hong-Fei Shi, Xiuwen TangAbstractAimsColorectal cancer (CRC) is the third most common cancer worldwide. Nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of many cytoprotective genes, plays a protective role in carcinogenesis. Recent studies have identified a specific gene-expression signature regulated by the Nrf2 pathway in lung adenocarcinoma and head-and-neck squamous cell cancer. However, the roles of Nrf2 in the development of colitis-associated colorectal...

ConclusionThe results of our series of 13 cases indicate that intraoral soft tissue metastatic carcinomas have a male predilection with a male to female ratio of 11:2, are commonly found in the gingiva and alveolar mucosa (76.9%), present frequently as an easy-bleeding pyogenic granuloma-like lesion (92.3%). In addition, the most common primary cancer site is the liver.

We report the first case of a patient with colon cancer who was diagnosed with a thyroid metastasis in a noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). A 55-year-old male patient presented with a 19  mm thyroid nodule in the inferior left lobe. It was EU-TIRADS 5 on echography and suspicious of papillary thyroid carcinoma (Bethesda V) on cytology. Macroscopically, the nodule was fleshy and completely encapsulated. At frozen section examination, it demonstrated follicular architecture with mild atypia. Inside the nodule was a focus of tumor with glandular architecture, marked cell...

ConclusionTo optimize targeting and visualization of the surgical field in right pelvic sidewall/paracolic gutter, robotic arms can be placed in a straight line from above the pubic symphysis extending to the left subcostal line and between the midline vertical and midclavicular lines. Robotic tumor debulking should be considered in selected patients with recurrent ovarian cancer who present with oligo-metastatic disease, in the absence of carcinomatosis.
