A study testing Image guided percutaneous microwave ablation in people with Sarcoma, run by Instituto do Cancer do Estado de São Paulo at 1 site in Brazil.
Trial summary
Patients with sarcoma and lung metastases have few therapeutic options, with poor response to systemic treatment. Many of them are not eligible to surgical treatments due to the high number and distribution of pulmonary lesions or due to comorbidities, which reduce the survival chances of these individuals.

- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- Patients over 18 years;
- Patients with lung metastases arising from sarcoma;
- Patients who are not eligible for surgery for medical reasons, including limited cardiopulmonary reserve. In this cases we will perform a pulmonary function test (PFT) to determine if the patient can withstand ablation;

- Patients with pulmonary lesions with dimensions up to 3,0 cm in the largest axial diameter;
- Patients with four or fewer lesions. In cases of bilateral metastases, we will evaluate the treatment of only one lung at a time, with an interval of at least two weeks for the treatment of the contralateral lung, respecting the clinical evolution of the patient.
- Patients with no extrapulmonary metastases or just indolent extrapulmonary disease;
- Patients with prior histopathological confirmation of pulmonary lesions.
Who cannot join
- Patients with primary disease without clinical control;
- Presence of uncontrolled extrapulmonary disease, including lymph node progression;

About this study
Official title: A Prospective, Phase III Study to Assess the Efficacy and Safety of Microwave Ablation of Metastatic Lung Sarcoma Lesions.
Patients with sarcoma and lung metastases have few therapeutic options, with poor response to systemic treatment. Many of them are not eligible to surgical treatments due to the high number and distribution of pulmonary lesions or due to comorbidities, which reduce the survival chances of these individuals. Given the high efficacy and overall increased survival demonstrated by recent studies, the minimally invasive treatments (mainly radiofrequency ablation) have gained ground. Although the microwave ablation is a promising new technique for the treatment of patients with pulmonary metastases, there are few studies in the literature to evaluate the efficacy and safety of this procedure in the above population.
Read the detailed description
This study was designed to prospectively evaluate the safety and effectiveness of microwave ablation therapy in the treatment of metastatic lung lesions secondary to sarcoma. This technique has been proven to be successful in producing greater areas of ablation, increasing the chances of success and reducing the possibility of local recurrence, especially when compared to radiofrequency ablation. There will be 60 consecutive patients diagnosed and treated at the oncology clinic at the São Paulo State Cancer Institute that are going to participate in this study, after meeting the inclusion/ exclusion criteria. This number may be increased up to approximately about 20 patients, according to the sample behavior in the initial analysis and follow-up. All patients will be informed about the benefits, risks, complications and limitations related to the procedure and written informed consent will be applied. Patients will also be informed that microwave ablation is a new technology in Brazil, despite the extensive international experience and the results already validated in the medical literature.
Logistic regression will be used to evaluate the success of the microwave ablation according to the characteristics of the lesion before the procedure. Logistic regressions for correlated data will be used to (a) evaluate the success of ablation according to all registered lesion characteristics, i.e., numeric characteristics (including tumor size and location) and categorical characteristics (histopathology of the primary tumor); (b) verify if combinations of two or more features of the lesions pose significant independent predictors for the success of ablation; and (c) construct a model to estimate the probability of success of the microwave ablation based on lesion characteristics before the procedure. The survival of patients will be assessed according to (a) the end result of the procedure (patients will be classified in two groups: an effective ablation group and a non-effective ablation group) and (b) the histopathological nature of the primary tumor. The survival rates will be calculated using the Kaplan-Meier test. The log-rank test (x² value of Cox-Mantel) will be used to determine statistically significant differences between the patients' survival rates. The value of P less than 0.05 will be considered to indicate a statistically significant difference for all analyses. Statistical software (Bias for Windows, version 8.4, Epsilon Verlag, Frankfurt, Germany) will be used.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Image guided percutaneous microwave ablationDevice
Also called Image guided percutaneous lung metastasis ablation
Lung metastasis from sarcoma will be treated with microwave antennas (SOLERO) and Ablation System and microwave generators (Angiodynamics), with power settings of 35-45W and an average ablation time of 15 minutes (range 10-30 minutes). The ablation time will be recorded for all procedures. The manufacturer's recommendations will be observed in all cases, since it is assured that patients are able to tolerate the total ablation time.
| Study group | Role | What they receive |
|---|---|---|
| Microwave ablation arm | Experimental | Single arm patients with lung sarcoma metastasis that will be treated with microwave ablation Receives: Device: Image guided percutaneous microwave ablation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Survival
Patients with sarcoma pulmonary metastases who are treated with microwave ablation of lung lesions may have higher overall survival rates compared to patients not subject to any kind of treatment or even chemotherapy/ palliative treatment. The literature contains data favorable to treating these patients with microwave ablation, since higher survival rates have been observed, especially when handled all lung lesions (R0).
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
A study testing Image guided percutaneous microwave ablation in people with Sarcoma, run by Instituto do Cancer do Estado de São Paulo at 1 site in Brazil.
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 8 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 3 Aug 2023. 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 Brazil. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Guilherme Lopes Pinheiro Martins, MD (+551138932000, guilherme.martins@hc.fm.usp.br), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Survival (time frame: 3 years). 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 NCT04510714, which also lists 10 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 3 Aug 2023.
