About this study

Official title: Distant Metastases and Long-Term Survival After Complete Resection of Neuroendocrine Tumors of the Appendix: An International Multicenter Study

The aim of the present project is to evaluate the frequency of distant metastases and clinically relevant relapse and mortality, respectively, of aNEN (Neuroendocrine Neoplasms of the Appendix) measuring 1 - 2 cm.

The investigators hypothesize that the mortality rate of aNET (Neuroendocrine Tumors of the Appendix) measuring 1 - 2cm is less than 1%. Furthermore, the investigators hypothesize that regional lymph node metastases of aNET measuring 1 - 2 cm are clinically not relevant and are not associated with reduced survival. The investigators therefore hypothesize that oncological right-sided hemicolectomy has no impact on long-term survival after complete resection of aNET measuring 1 - 2 cm and that the malignant potential quo ad vitam of these tumors is lower than the risk of oncological hemicolectomy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinically relevant relapse of aNET measuring 1 - 2 cm in a population based manner

    Measured: 10 years

  2. Clinically relevant mortality of aNET measuring 1 - 2 cm in a population based manner

    Measured: 10 years

  3. Frequency of distant metastases in aNET measuring 1-2 cm

    Measured: 10 years

Secondary outcomes (3)
  1. Association of histological risk factors in aNET measuring 1 - 2 cm and qualifying for oncological right-sided hemicolectomy according to ENETS guidelines with the occurrence of regional lymph node and distant metastases

    Measured: 10 years

  2. Relationship between regional lymph node metastasis and survival in patients with aNET measuring 1 - 2 cm

    Measured: 10 years

  3. Long-term survival after complete resection of aNET measuring 1 - 2 cm with or without oncological right-sided hemicolectomy

    Measured: 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of Neuroendocrine Tumors of the Appendix, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinically relevant relapse of aNET measuring 1 - 2 cm in a population based manner (time frame: 10 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03852693, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2024.
