Radiofrequency Ablation in Treating Patients With Stage I Non-Small Cell Lung Cancer

26 de enero de 2017 actualizado por: Alliance for Clinical Trials in Oncology

A Pilot Study of Radiofrequency Ablation in High-Risk Patients With Stage IA Non-Small Cell Lung Cancer

This pilot clinical trial studies how well radiofrequency ablation works in treating patients with stage IA non-small cell lung cancer. Radiofrequency ablation uses high-frequency electric current to kill tumor cells. Computed tomography (CT)-guided radiofrequency ablation may be a better treatment for non-small cell lung cancer.

Descripción general del estudio

Descripción detallada

PRIMARY OBJECTIVES:

I. To assess the overall 2-year survival rate after radiofrequency ablation (RFA).

SECONDARY OBJECTIVES:

I. To assess freedom from regional or distant recurrence. II. To assess freedom from local recurrence in the ablated lobe. III. To estimate the number of procedures deemed technical successes. IV. To evaluate procedure-specific morbidity and mortality. V. To explore the utility of immediate (within 96 hours) post-RFA positron emission tomography (PET) in predicting overall survival and local control.

VI. To explore the effect of RFA on both short-term (3 months post-RFA) and long-term (24 months post-RFA) pulmonary function.

OUTLINE:

A radiofrequency electrode is placed by CT guidance into the target tumor. Patients undergo RFA directly to the tumor for up to 12 minutes to obtain an intratumoral temperature > 60° Celsius (C). Patients may receive 3 RFA treatments (a total of 36 minutes) to obtain the target temperature.

After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months for 1 year.

  • Patient must have been evaluated by a thoracic surgeon and been deemed at high risk for a lung resection; NOTE: if the evaluating surgeon is not a member of American College of Surgeons Oncology Group (ACOSOG), then an ACOSOG thoracic surgeon must confirm with dated signature that the patient is high-risk and appropriate for RFA
  • Patient must have fludeoxyglucose F 18 (FDG)-PET and a CT scan of the chest with upper abdomen within 60 days prior to pre-registration; patient must have pulmonary function tests (PFTs) within 120 days prior to registration
  • Patient must have an Eastern Cooperative Oncology Group (ECOG)/Zubrod performance status 0, 1, or 2
  • Patient must meet at least one major criterion or meet a minimum of two minor criteria as described below:

    • Major criteria

      • Forced expiratory volume in one second (FEV1) =< 50% predicted
      • Diffusing capacity of the lung for carbon monoxide (DLCO) =< 50% predicted

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Overall Time to Local Failure
Periodo de tiempo: Up to 2 years
The overall time to local failure was defined as the time from registration to documentation of > local failure. The local failure was defined as the recurrence in the same lobe or hilum (N1 nodes) or progression at the ablated site after treatment affects have subsided.
Up to 2 years
Overall Time to Recurrence
Periodo de tiempo: Up to 2 years
The overall time to recurrence was defined as the time from registration to documentation of disease recurrence. If a patient dies without a documentation of disease recurrence, the patient will be considered to have had tumor recurrence at the time of their death unless there is sufficient evidence to conclude no recurrence occurred prior to death.
Up to 2 years
Number of Procedures Deemed Technical Successes
Periodo de tiempo: Up to 2 years
The number of procedures deemed technical successes is defined as the number of patients with a RFA procedures deemed a technical success. A technical success is defined as follows: The pertinent captured images from the treatment CT showing RFA electrode placement and the recorded RFA generator parameters (e.g. impedance, current, power, treatment time and maximum intra-tumoral temperature) were reviewed by the quality control panel to determine technical success.
Up to 2 years
Incidence of Adverse Events
Periodo de tiempo: Up to 2 years
The National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 was used to evaluate adverse event.> Grade 1: mild; Grade 2: moderate; Grade 3: Severe; Grade 4: Life Threatening; Grade 5: Death.
Up to 2 years
