Tag: RB1

The RB1 gene provides instructions for making a protein called pRB. This protein acts as a tumour suppressor, which means that it regulates cell growth and keeps cells from dividing too fast or in an uncontrolled way. Under certain conditions, pRB stops other proteins from triggering DNA replication, the process by which DNA makes a copy of itself. Because DNA replication must occur before a cell can divide, tight regulation of this process controls cell division and helps prevent the growth of tumors. Additionally, pRB interacts with other proteins to influence cell survival, the self-destruction of cells (apoptosis), and the process by which cells mature to carry out special functions (differentiation).

RB1 is often used when working out whether Neuroendocrine Neoplasms are well differentiated (Neuroendocrine Tumour) or poorly differentiated (Neuroendocrine Carcinoma).

Grading and Staging – Neuroendocrine Neoplasms (incorporating WHO 2021 changes)

Patient Advocacy

One of the most discussed and sometimes confusing subjects on forums is the staging and grading of Neuroendocrine Neoplasms (NENs). Mixing them up is a common error and so it's important to understand the difference despite the apparent complexity.Stage vs GradeIn the most basic of terms, stage is the spread or extent of cancer and grade is the aggressiveness of cancer. They are totally different things and an understanding of both is important as they are critical to predicting outcomes (to a certain extent) and guiding therapy. There is no correlation between the two, you can have the lowest grade with the highest stage (actually very common with NETs). Remember S for Stage (Spread), G for Grade (Growing fast or slow)The stage is essentially worked out via scans and biopsy,…

November is always busier as I help spread awareness for 10th Nov (remembering that every day is 10th Nov on my site!). I also managed to push out quite a few blogs, some ‘remasters’ from 2014 but with their originality from that time. Others include the ENETS Guideline series, a work in progress. I’m thankful […]

European Neuroendocrine Tumor Society (ENETS) 2023 guidance paper for Digestive Neuroendocrine Carcinoma

This ENETS guidance paper, developed by a multidisciplinary working group, provides up-to-date and practical advice on the diagnosis and management of digestive neuroendocrine carcinoma, based on recent developments and study results. These recommendations aim to pave the road for more standardized care for our patients resulting in improved outcomes. However, it’s true to say that […]

Neuroendocrine Cancer – Clinical Esoterica

One of the key awareness messages for Neuroendocrine Cancer is the hormonal syndromes that can often accompany the diagnosis for many people. As it’s a difficult disease to diagnose, many people struggle with these syndromes for some time before formal diagnosis of Neuroendocrine Cancer. Some continue to struggle after. Neuroendocrine Cancer can often be uncannily […]

Neuroendocrine Cancer – The F Words

When I first created my blog in April 2014, I had to find some material to lead up to my 84 mile walk (at the time, it was a temporary vehicle for the single purpose of raising money for charity). An idea I had probably led to the longer term survival of this blog after […]

Laughter is the best medicine

Laughter is important. This is a remastered version of one of my early blog posts. It centred on a ‘get-well’ card I received recuperating in hospital after my first major surgery. The person who sent it knew I had a sense of humour, and it did make me smile. My surgeon’s secretary came to visit […]
