They can appear benign endoscopically but the presence of malignant invasion histologically poses a difficult and often controversial clinical scenario. Emphasis should be initially focused on the endoscopic assessment of these lesions.

Suitable polyps should be resected en-bloc, if possible, haggitt classification of polyps facilitate thorough evaluation by pathology.

In these cases, proper attention must be given to the risks of residual haggitt classification of polyps in the bowel wall or in the surrounding lymph nodes. If resection is not feasible endoscopically, then these patients should be referred for surgical resection.

Management of malignant colon polyps: Current status and controversies

This review will discuss the important prognostic features of malignant polyps that will most profoundly affect this risk profile. Additionally, we will discuss effective strategies for their overall management. Malignant polyp, Endoscopic mucosal resection, Submucosal invasion, Early colon cancer, Lymphovascular invasion, Tumor budding Core tip: This article discusses the important prognostic features of malignant polyps that will ultimately inform the overall management.

Fortunately, the incidence of colorectal cancer is declining, in large part due to more prevalent educational and screening programs designed to detect early cancers and their precursor polyps[ 1 ].

This adenoma-carcinoma sequence is well described and is often an indolent process that can take many years to fully manifest after a stepwise accumulation of genetic haggitt classification of polyps 23 ].

However, the treatment of larger lesions can be more challenging haggitt classification of polyps require more advanced techniques, such as endoscopic mucosal resection EMR or endoscopic submucosal dissection ESDwhich are being used with increasing frequency in specialized centers.

These techniques afford the opportunity for complete excision rather than a piecemeal approach. This is a critical initial step in the overall management of malignant polyps because a complete excision facilitates a more comprehensive histological examination.

Unfortunately, this is not the typical presentation in routine clinical practice. More commonly, a patient presents for evaluation after a resected polyp, thought to have a benign appearance at endoscopy, is found to have an invasive focus of adenocarcinoma on final pathological haggitt classification of polyps.

This scenario can often become further complicated if the polypectomy site is not marked at the initial endoscopy. This limits endoscopic re-evaluation, if needed, and renders untrustworthy the proper identification of the involved segment of colon if definitive resection is deemed appropriate.

Analysis of the existing body of data demonstrates that this is still a controversial topic that generally requires a multidisciplinary approach. Morphologically, polyps can be broadly classified as either pedunculated or sessile.

Pedunculated polyps are those attached to the colonic mucosa by a stalk of variable length, while sessile polyps grow in a more haggitt classification of polyps pattern over the mucosa with less separation of the adenomatous epithelium from the underlying layers of the bowel wall[ 4 ].

The latter are often, understandably, more difficult to completely remove with conventional snare polypectomy, depending on their location within the colon and their size.

Management of malignant colon polyps: Current status and controversies

Using a prospective registry of colorectal polyps, Nusko et al[ 5 ] performed a multivariate analysis of adenomas detected at colonoscopy.

Larger polyps between 1. Polyps include adenomatous, inflammatory, hamartomatous, and hyperplastic lesions. These polyps consist of epithelial growths of abnormal glands accompanied by a varying amount haggitt classification of polyps villous component tubular, tubulovillous, and villous adenomas.

Polyps can be classified by their macroscopic structural configuration, such as sessile broad base or pedunculated, and by their histologic appearance including villous component and degree of dysplasia.


Although these polyps are benign, varying degrees haggitt classification of polyps dysplasia may be seen within them. Severe dysplasia, high-grade dysplasia, and carcinoma haggitt classification of polyps situ are all synonymous and denote the high risk of malignant transformation over time.

Other factors affecting risk of malignancy include polyp size, extent of villous component, and patient age. Mark's Hospital, the degree of dysplasia was clearly associated with risk of the polyp harboring malignancy. The investigators showed that only 5. Furthermore, the size of the polyp is associated with risk of malignancy, with studies showing the presence of cancer in 1.
