Are tumour grade and tumour budding equivalent in colorectal cancer? A retrospective analysis of 771 patients.

Tumour grade is traditionally considered in the management of patients with colorectal cancer. However, a large body of literature suggests that a related feature, namely tumour budding, may have a more important clinical impact. The aim of our study is to determine the correlation between tumour grade and tumour budding and their impact on patient outcome.

Tumor budding in colorectal carcinoma: An institutional interobserver reliability and prognostic study of colorectal adenocarcinoma cases.

Colorectal carcinomas are one of the most commonly diagnosed malignancies. There are many prognostic factors relating to clinical course and disease progression, including tumor stage, metastasis, and tumor budding. In 2016, the International Tumor Budding Consensus Conference (ITBCC) created a system to uniformly assess tumor budding. This system includes a 3-tier system for the grading of tumor budding. In the past, there lacked uniform consensus, however the general grading practice was based on a 2-tier...

Tumour budding predicts increased recurrence after curative resection for T2N0 colorectal cancer

Tumour budding is defined as the presence of a cluster of fewer than 5 cells along the invasive margin. It may confer a worse prognosis in colorectal cancer, but its importance in pT2N0 colorectal cancer is unknown. This study aimed to determine the prognostic value of tumour budding in pT2N0 colorectal cancer.

How to measure tumour response in rectal cancer? An explanation of discrepancies and suggestions for improvement.

Various methods categorize tumour response after neoadjuvant therapy, including down-staging and tumour regression grading. Response categories allow comparison of different treatments within clinical trials and predict outcome. A reproducible response categorization could identify subgroups with high or low risk for the most appropriate subsequent treatments, like watch and wait. Lack of standardization and interpretation difficulties currently limit the usability of these approaches. In this review we des...

Accuracy of radiomics-based feature analysis on multiparametric MR images for non-invasive meningioma grading.

Meningioma grading is a relevant subject with respect to therapy decisions in complete or partial resection, observation and radiotherapy as higher grades are associated with tumour growth and recurrence. The differentiation of low and intermediate grades is particularly challenging. This study attempts to apply radiomics-based shape and texture analysis on routine multiparametric MRI from different scanners and institutions for grading.

Tumour Budding/T-cell infiltrates in Colorectal Cancer: Proposal of a Novel Combined Score.

The TNM classification system is used for prognostication purposes and to guide patient management. However, in colorectal cancer (CRC), additional markers are needed to stratify prognostic subgroups. From large bodies of research, two promising markers have emerged: Tumour budding and T-cell host response (CD3, CD8 and CD45RO infiltrates). However, attempts to combine these two parameters have been sparse. The aim of this study was to perform an assessment of potential protagonists that could be used in a ...

Higher underestimation of tumour size post-neoadjuvant chemotherapy with breast magnetic resonance imaging (MRI)-A concordance comparison cohort analysis.

The Relationship Between Tumor Budding, Tumor Microenvironment, and Survival in Patients with Primary Operable Colorectal Cancer.

Tumor budding is an independent prognostic factor in colorectal cancer (CRC) and has recently been well-defined by the International Tumour Budding Consensus Conference (ITBCC).

The Immune Microenvironment in Breast Carcinoma: Predictive and Prognostic Role in the Neoadjuvant Setting.

The prognostic value of the immune cell infiltrate in the breast carcinoma microenvironment is still uncertain. We reviewed published articles analysing the infiltration of inflammatorycells in the microenvironment of breast carcinoma. Data revealed the importance of infiltration of these immune cells in the prognosis of breast carcinoma, particularly the triple-negative and HER2-positive phenotypes. Tumour-infiltrating lymphocytes and their subtypes play a fundamental role in predicting the pathological co...

Correction to: Pattern and Significance of Tumour Budding in Colorectal Carcinomas Using ITBCC Guidelines: a Low Resource Setting Practice Observation.

The original version of this article unfortunately contained a mistake. In Table 2, the number 36 under "N" should be 96 and "Tumour size in cm (range)" should read "Tumour size in cm."

Lack of Standardization in the Processing and Reporting of Post-Neoadjuvant Breast Cancer Specimens: A Survey of Canadian Pathologists and Pathology Assistants.

The use of neoadjuvant therapy in the management of early-stage invasive breast cancer is increasing. Residual Cancer Burden and other similar tools use pathologic characteristics of post-neoadjuvant therapy breast tumors to determine long-term outcome. However, there are no standardized guidelines for the pathologic evaluation of these specimens in the routine clinical setting.

Sonographically guided metalic clip placement for tumour localization in early breast cancer patients undergoing neoadjuvant chemotherapy.

Fewer tumour draining sentinel nodes in patients with progressing muscle invasive bladder cancer, after neoadjuvant chemotherapy and radical cystectomy.

To examine the relationship between the number of tumour draining sentinel nodes (SNs) and pathoanatomical outcomes, in muscle-invasive bladder cancer (MIBC), in patients undergoing neoadjuvant chemotherapy (NAC) and radical cystectomy (RC).

Multislice spiral CT images combined with CEA and lymphocyte-to-neutrophil ratio predict recurrence and post-operative metastasis of rectal cancer.

To explore the early predictors of post-operative recurrence and metastasis of rectal cancer, analyse the associated risk, and construct a model. Retrospective collection. Four hundred patients with rectal cancer underwent surgical resection and pathological diagnosis from September 2013 to September 2014. During the post-operative period, the patients were tested by imaging examination, serum tumour markers, and routine blood follow-up for at least 3 years. Preoperative CT examination of tumour size, lymph...

MRI-based guidelines for selective neoadjuvant treatment in rectal cancer: Does MRI adequately predict the indication for radiotherapy in daily practice in a large teaching hospital.

According to new Dutch guidelines for rectal cancer, MRI-defined tumour stage determines whether preoperative radiotherapy is indicated. Therefore, we sought to evaluate if preoperative MRI accurately predicts the indication for neoadjuvant treatment in rectal cancer cases in daily practice according to the new Dutch guidelines.

Human papillomavirus oncoproteins and post translational modifications: generating multifunctional hubs for overriding cellular homeostasis.

Human Papillomaviruses are major human carcinogens, causing around 5% of all human cancers, with cervical cancer being the most important. These tumours are all driven by the two HPV oncoproteins E6 and E7. Whilst their mechanisms of action are becoming increasingly clear through their abilities to target essential cellular tumour suppressor and growth control pathways, the roles that post-translational modifications of E6 and E7 plays in the regulation of these activities remains unclear. Here we discuss t...

Comparing CAR T-cell toxicity grading systems: application of the ASTCT grading system and implications for management.

Various grading systems are currently used for chimeric antigen receptor (CAR) T-cell-related toxicity, cytokine release syndrome (CRS), and immune effector cell-associated neurotoxicity syndrome (ICANS). We compared the recently proposed American Society for Transplantation and Cellular Therapy (ASTCT) grading system to other grading scores in 2 populations of adults: patients (n = 53) with B-cell acute lymphoblastic leukemia (B-ALL) treated with 1928z CAR T-cells ( #NCT01044069), and pat...

Effect of post-implant exercise on tumour growth rate, perfusion and hypoxia in mice.

Preclinical studies have shown a larger inhibition of tumour growth when exercise begins prior to tumour implant (preventative setting) than when training begins after tumour implant (therapeutic setting). However, post-implantation exercise may alter the tumour microenvironment to make it more vulnerable to treatment by increasing tumour perfusion while reducing hypoxia. This has been shown most convincingly in breast and prostate cancer models to date and it is unclear whether other tumour types respond i...

Physical imaging phantoms for simulation of tumour heterogeneity in PET, CT and MRI: an overview of existing designs.

In oncology, lesion characterisation is essential for tumour grading, treatment planning, and follow-up of cancer patients. Hybrid imaging systems, such as SPECT/CT, PET/CT or PET/MRI, play an essential role for the non-invasive quantification of tumour characteristics. However, most of the existing approaches are challenged by intra- and inter-tumour heterogeneity. Novel quantitative imaging parameters that can be derived from textural feature analysis (as part of radiomics) are promising complements for i...

Investigating the duality of function in the cellular transformation of mouse fibroblasts.

is a tumour suppressor in breast, ovarian, prostate, thyroid and other cancers, attributed to its ability to reduce oncogenic Akt-signaling. However, emerging studies show that also has tumour-promoting properties in cancers including acute myeloid leukemia, colon cancer, melanoma and breast cancer. Together these findings suggest that may be a context dependent cancer gene. Whether functions solely in a tumour suppressing or tumour promoting manner, or both in non-transformed cells is currently not clea...

Validation of the AAST Grading System for Acute Mesenteric Ischemia - more than anatomic severity is needed to determine risk of mortality.

Acute mesenteric ischemia (AMI) is a highly morbid disease with a diverse etiology. The American Association for the Surgery of Trauma (AAST) proposed a disease specific grading scale intended to quantify severity based upon clinical, imaging, operative and pathology findings. This grading scale has not been yet been validated for AMI. The goal of this study was to evaluate the correlation between the grading scale and complication severity.

Automatic grading of human blastocysts from time-lapse imaging.

Blastocyst morphology is a predictive marker for implantation success of in vitro fertilized human embryos. Morphology grading is therefore commonly used to select the embryo with the highest implantation potential. One of the challenges, however, is that morphology grading can be highly subjective when performed manually by embryologists. Grading systems generally discretize a continuous scale of low to high score, resulting in floating and unclear boundaries between grading categories. Manual annotations ...

Drivers of 30-/90-day post-op mortality following neoadjuvant chemoradiation for esophageal cancer.

Neoadjuvant chemoradiation followed by esophagectomy is a standard of care for locally advanced esophageal cancers. The CROSS trial reported a 30-day mortality rate of 6%. We sought to evaluate 30- and 90-day mortality in similar patients in the United States and identify predictors of higher mortality rates.

Pivotal role of NF-κB in cellular senescence of experimental pituitary tumours.

The molecular mechanisms underlying the capability of pituitary tumours to avoid unregulated cell proliferation are still not well understood. However, the NF-κB transcription factor, which is able to modulate not only cellular senescence but also tumour progression, has emerged as a targeted candidate. This work was focused on the NF-κB role in cellular senescence during the progression of experimental pituitary tumours. Also, the contribution of the signalling pathways in senescence-associated NF-κB ac...
