Lymph node regression after neoadjuvant chemoradiotherapy in rectal cancer.

Aims: Lymph node metastases (LNM) are one of the most important prognostic indicators in solid tumours and a major component of cancer staging. Neoadjuvant therapy might influence nodal status by induction of regression. Our aim is to determine the prevalence and role of regression of LNM on outcomes in patients with rectal cancer.

Pseudobudding: ruptured glands do not represent true tumor buds.

Tumor budding (TB) is a strong biomarker of poor prognosis in colorectal cancer and other solid cancers. TB is defined as isolated single cancer cells or clusters of up to four cancer cells at the invasive tumor front. In areas with a large inflammatory response at the invasive front, single cells and cell clusters surrounding fragmented glands are observed appearing like TB.

Fully Automated Tumor Bud Assessment in Hematoxylin and Eosin-Stained Whole Slide Images of Colorectal Cancer.

Tumor budding (TB), the presence of single cells or small clusters of up to 4 tumor cells at the invasive front of colorectal cancer (CRC), is a proven risk factor for adverse outcomes. International definitions are necessary to reduce interobserver variability. According to the current international guidelines, hotspots at the invasive front should be counted in hematoxylin and eosin (H&E)-stained slides.

Do the Well Known Prognostic Parameters in Pancreatic Ductal Adenocarcinoma Really Reflect Survival?

Objective: Pancreatic ductal adenocarcinoma is an aggressive tumor with short survival. In this study we aimed to investigate the effect of well-known prognostic parameters on survival in these tumors.

Material And Method: A total of 56 pancreatic ductal adenocarcinoma cases diagnosed between 2005 and 2014 were included in the study.
