About this study

Official title: A Phase II Study to Evaluate Radiofrequency Ablation of Renal Cancer

RATIONALE: Radiofrequency interstitial tissue ablation may kill tumor cells by heating tumors to several degrees above body temperature.

PURPOSE: This phase II trial is studying radiofrequency interstitial tissue ablation to see how well it works in treating patients with localized renal cell carcinoma (kidney cancer).

Read the detailed description

OBJECTIVES:

Primary

  • Evaluate the efficacy of radiofrequency interstitial tissue ablation in terms of tumor destruction or slowed tumor growth rate in patients with localized renal cell carcinoma.

Secondary

  • Assess the toxicity of this treatment regimen in these patients.

OUTLINE: Patients undergo percutaneous radiofrequency interstitial tumor ablation (RFA). Patients are offered laparoscopy-assisted percutaneous RFA in the operating room if their tumors are not safely accessible. Intra-operative ultrasound is used to confirm probe placement and to monitor treatment delivery. If the target temperature or impedance are not reached, treatment is repeated no more than twice. No more than 5 tumors are treated per kidney.

All patients are followed at 2 to 3 months, 6 months, and then at 1 year.

Patients with tumors greater than 2 cm in diameter are followed every 6 months for up to 5 years. Patients whose tumors become greater than 3 cm are recommended for surgery and removed from study if surgery is performed.

PROJECTED ACCRUAL: A total of 63 patients will be accrued for this study within 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing laparoscopic surgery, radiofrequency ablation and thermal ablation therapy in people with Kidney Cancer, run by National Cancer Institute (NCI) at 1 site in United States.

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

Who may be eligible to take part?

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 29 Apr 2015. 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 United States. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Response. 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 NCT00019955, which also lists 11 linked publications.

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 29 Apr 2015.
