NCT02328664

Brief Summary

After endoscopic removal of a colorectal polyp that harbors (unexpected) adenocarcinoma, pathology usually can not guarantee a radical resection from an oncological point of view. In such case, additional surgical resection is advised. However, only in 15% of patients, residual adenocarcinoma is found. This study investigates the sensitivity of biopsies from the polypectomy scar for residual adenocarcinoma.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity of biopsies for residual cancer

    The number of patients with endoscopic biopsies containing adenocarcinoma divided by the number of patients with adenocarcinoma in the resected specimen.

    up to 1 year

Secondary Outcomes (5)

  • 90-day mortality after rescue surgery

    91 days from surgery

  • The sensitivity of biopsies for residual cancer in the bowel wall

    up to 1 year

  • The number of complications (defined according to GCP) after biopsies from the polypectomy scar

    up to 30 days

  • The sensitivity of global endoscopic assessment of polypectomy site for residual cancer at initial and follow-up endoscopy (to take scar biopsies)

    up to 1 year

  • The proportion of patients with residual cancer in the resected specimen if malignancy was unsuspected during the endoscopic polypectomy

    up to 1 year

Study Arms (1)

Flexible sigmoidoscopy or colonoscopy

OTHER

Subjects will undergo these investigation to take biopsies from the polypectomy scar.

Procedure: Flexible sigmoidoscopy or colonoscopy

Interventions

Depending on the localization of the scar of the malignant polyp, either a flexible sigmoidoscopy or colonoscopy will be done to take biopsies from the polypectomy scar.

Flexible sigmoidoscopy or colonoscopy

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 or above.
  • Endoscopically removed colorectal lesion with the following pathological characteristics:
  • A moderately-to-well differentiated adenocarcinoma.
  • If possible to judge: distance between adenocarcinoma and vertical or lateral resection margin is less than 1 mm.
  • In case of piecemeal resection: unjudgeable radicality (mostly due to loss of orientation and multiple fragments).
  • Absence of / unjudgeable lymphatic / vascular invasion.
  • No or only grade I tumor budding.
  • No suspicion of dissemination on the following investigations: serum carcino-embryonic antigen, a computer tomographic (CT) scan of the abdomen and a chest X-ray; in case of a rectal tumor (less than 15 cm from the anal verge): an additional magnetic resonance imaging of the rectum.
  • Operation is advised in agreement with the Dutch Guideline on Colorectal cancer, planned and agreed on by the patient.
  • Written informed consent is obtained.

You may not qualify if:

  • Pathology shows one or more of the following characteristics:
  • A radical en-bloc resection with a free vertical and lateral margin of ≧ 1 mm.
  • A poorly differentiated or signet-cell containing adenocarcinoma.
  • Tumor budding grade II-III.
  • Patients already receiving anti-tumor treatment for another tumor or a synchronic colorectal cancer.
  • Patients in whom a second-look endoscopy would require major and unacceptable effort and / or resources, for instance clinical admission for bowel preparation, long travel, general anesthesia, extremely difficult to reach polypectomy site. Such at the decision of the patient and / or treating physician.
  • Patient is planned for trans-anal surgery.
  • Patient is not planned for surgery.
  • Patient is pregnant.
  • Patient does not provide written informed consent or is unable to provide such.
