Trial Summary

What is the purpose of this trial?

This is a single-centre, Phase II, prospective study designed to assess BALF and TA-derived biomarkers in relation to metastatic burden in STS patients. BALF and TA samples will be collected during routine bronchoscopy performed as part of standard care at Toronto General Hospital (TGH). Additionally, tissue samples of lung metastases and adjacent normal lung will be collected and used to correlate the identified biomarkers.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Bronchoscopy, Metastasectomy for cancer?

Metastasectomy, which involves surgically removing cancer that has spread to the lungs, can be the only curative option for some patients and may improve survival if the cancer is completely removed. Bronchoscopy, a procedure to look inside the lungs, is valuable for diagnosing lung metastases, especially in certain types of cancer like colorectal and breast cancer.12345

Is bronchoscopy generally safe for humans?

Bronchoscopy is generally considered a safe procedure, but complications can occur, such as pneumothorax (collapsed lung), bleeding, and in rare cases, death. Safety data from various studies suggest that while it is safe for many patients, certain conditions or trainee involvement may increase the risk of complications.678910

How is bronchoscopy used in cancer treatment different from other treatments?

Bronchoscopy is a unique treatment for cancer as it is a minimally invasive procedure that allows doctors to directly view the airways and collect samples for diagnosis, particularly useful for detecting lung metastases. Unlike other treatments that may rely on imaging or systemic therapies, bronchoscopy provides direct access to the lung tissue, making it valuable for diagnosing and managing metastatic lung tumors.34111213

Eligibility Criteria

This trial is for patients with sarcoma, a type of cancer that may spread to the lungs. Participants must be undergoing routine bronchoscopy at Toronto General Hospital as part of their standard care and can provide tissue samples from lung metastases.

Inclusion Criteria

Ability to understand and willingness to sign a written informed consent document
I have been diagnosed with soft tissue sarcoma.
I am scheduled for lung surgery as part of my treatment.

Exclusion Criteria

I had cancer before, but it was either skin cancer or another type cured over 2 years ago with no current signs.

Findings from Research

A study analyzing data from 540,747 lung cancer patients revealed that the incidence of adverse events during lung biopsies increased significantly from 24% in 2001 to 38% in 2010, indicating a growing concern for patient safety.
Patients who experienced adverse events had longer hospital stays and a significantly higher risk of in-hospital mortality, with an adjusted odds ratio of 5.9, highlighting the need for improved safety measures in lung biopsy procedures.
Increasing Numbers and Reported Adverse Events in Patients with Lung Cancer Undergoing Inpatient Lung Biopsies: A Population-Based Analysis.von Itzstein, MS., Gupta, A., Mara, KC., et al.[2020]
In a 15-month study of 697 patients undergoing advanced diagnostic bronchoscopy, severe complications were rare, occurring in only 2.4% of patients, but they had serious consequences, including unplanned hospital visits and deaths.
Many complications occurred days or weeks after the procedure, highlighting the need for proactive monitoring to identify and manage these delayed adverse events effectively.
Thirty-Day Complications, Unplanned Hospital Encounters, and Mortality after Endosonography and/or Guided Bronchoscopy: A Prospective Study.Magnini, D., Sotgiu, G., Bello, G., et al.[2023]
In a study of 1,100 interventional pulmonology procedures, trainee involvement was linked to longer procedure times (average of 50.81 minutes compared to 32.49 minutes) and increased sedation requirements, indicating a potential impact on efficiency.
The presence of trainees also correlated with a higher complication rate (4.5% with trainees vs. 1.2% without), suggesting that while training is essential, it may pose additional risks to patients during procedures.
