Neoplasia detected in a third of patients under 50 after colorectal screening

19th January 2022

Neoplasia (precancerous lesions) have been detected in a third of patients aged 45 to 49 years of age after colorectal screening

The presence of neoplasia or precancerous lesions, have been identified after colorectal screening in patients aged 45 to 49 years of age, highlighting the need for lowering the age of such screening for average risk individuals. This was the finding from an examination of real-world outpatient colonoscopy data by a team from the Dr. Henry D. Janowitz Division of Gastroenterology, New York, US.

Colorectal cancer is a malignant tumour that forms in the tissues of the colon and is often grouped together with rectal cancer, due to the fact that these cancers share common features. During 2020 in Europe, colorectal cancer became the second most common cancer and the second highest cause of cancer death, accounting for 12.7% of all new cancer diagnoses and 12.4% of cancer deaths. Moreover, the importance of screening has been highlighted in a study which observed that the largest decreases in colorectal cancer mortality were seen in countries with long-standing screening programmes.

The incidence of early-onset colorectal cancer (i.e., cases in those aged under 50 years of age) has seen a world-wide increase, especially in high-income countries although the reasons behind this increase are uncertain. In addition, data suggests that the incidence of deaths due to early-onset colorectal cancer are also rising, had that these had increased by 1.3% annually between 2008 and 2017, in those aged younger than 50 years. Despite this, most screening programmes in Europe begin at 50 years of age.

But could there be an advantage from earlier screening and could this help identify those with neoplasia? This was the aim of the present study and the US team analysed data from a large and nationally representative set of outpatient colonoscopies to identify colorectal neoplasia among patients aged 18 to 54 years of age. They undertook a retrospective analysis of colonoscopy data and compared a ‘young onset group (defined as aged 18 to 49) with those aged 50 to 54 years.

Findings

A total of 562,559 colonoscopy procedures were included in the analysis, 145,998 of which were undertaken in those aged 18 – 44 years and 79,934 in those aged 45 – 49 years.

Among individuals aged 45 – 49, approximately 32% had any form of neoplasia, 7.5% had advanced premalignant lesions and 0.58% had colorectal cancer with a neoplasia present in 26.6% of those aged 40 to 44 years.

Discussing their findings, the authors stated that in a representative sample of patients under 50 years of age, the prevalence of any neoplasia among those aged 45 – 49 were almost as high as in those in the 50 to 54 year olds. They concluded that lowering the screening age to 45 will likely enable the detection of important pathology more frequently.
