Fluorescence-Guided Surgical Resection for Reducing Unexpected Positive Margins in Patients With Sarcoma, SarcoSIGHT Trial

12 июня 2026 г. обновлено: City of Hope Medical Center

SarcoSIGHT: A Randomized-Control Trial of Fluorescence Guided Sarcoma Surgery Versus the Standard of Care

This phase II trial compares standard of care surgical resection to fluorescence-guided surgical resection using indocyanine green and fluorescence imaging for reducing unexpected positive margin rates in patients with sarcoma. Surgical margins are one of the criteria used in assessing the effectiveness of a given surgical procedure. They are the edges or border of the tissue removed in cancer surgery. A negative margin means that the resected tumor is surrounded by normal tissue, which implies there is no disease left in the patient. By contrast, a positive margin means that sarcoma cells are visible at the edge of the tumor. Positive margins may be classified as planned when they are expected pre-operatively due to the preservation of a critical structure, or unexpected when the pathologist reports the presence of tumor at the margin despite the surgeon having intended to remove it in its entirety. Fluorescence-guided surgery is an established surgical method that involves the administration of fluorescent dye (in this case, indocyanine green) into the tumor, which can then be visualized with a special camera during surgery to help surgeons identify tumor versus healthy tissue. Fluorescence-guided surgery may reduce the rate of unexpected positive margins in patients undergoing surgery for sarcoma.

Подробное описание

PRIMARY OBJECTIVE:

I. To determine whether there is a reduction in the unexpected positive margin rate (UPM) in patients receiving fluorescence-guided surgery (FGS) using indocyanine green (ICG) compared to standard of care (SoC).

SECONDARY OBJECTIVE:

I. To determine the effect of FGS using ICG compared to the SoC over a 12-month period.

EXPLORATORY OBJECTIVE:

I. To determine the role of ICG in the pathological margin assessment of resected sarcoma specimens whilst improving understanding of the cellular mechanisms of FGS using ICG.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients undergo standard of care surgical resection.

ARM II: Patients receive ICG intravenously (IV) 12-24 hours prior to their scheduled surgery. Patients then undergo FGS with intraoperative fluorescence imaging.

After completion of study treatment, patients are followed up at 1, 3, 6, and 12 months.

Временное ограничение
Unexpected positive margin (UPM) rate
Временное ограничение: At 6 months post-surgery
The margin status of each tumor will be taken from the pathology report for each patient enrolled in the trial. This will be recorded at six months post- surgery and will be classified according to the R classification system. The UPM rate for each arm will be defined by calculating the percentage of patients in that arm with a UPM on histopathological assessment of the resection specimen. The percentage of patients with unexpected positive margins will be calculated for each group to give the unexpected positive margin rate. This will then be compared between the two groups. Will use a logistic regression that adjusts key covariates including stratification factors used in the randomization. A Wald test and a 95% confidence interval will be extracted from this model. A two-sided p-value will be found from the Wald test.
At 6 months post-surgery

Intraoperative complications
Временное ограничение: During surgical resection
Intraoperative complications may include blood loss requiring transfusion, inadvertent damage to nerves, inadvertent damage to tendons/ligaments, inadvertent damage to bony structures, myocardial infarction, stroke, other events determined by the principal investigator to be a complication of the surgery. Will be compared between the two groups at the day of operation. Descriptive analysis will be performed to analyze the nature of the data. Secondary outcomes with binary/multiple measures will be analyzed with logistic regression. For variables with continuous measure, appropriate regression models will be used. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.

Recurrence
Временное ограничение: Up to 12 months
Local/regional/distal recurrence is defined as the recurrence of sarcoma at the site of primary resection (local) or at a site other than that of the primary tumor, including distal metastasis. Investigations must be tailored to circumstances but where possible should include histological confirmation. Will be compared between the two groups at the 12-month time point. Descriptive analysis will be performed to analyze the nature of the data. Secondary outcomes with binary/multiple measures will be analyzed with logistic regression. For variables with continuous measure, appropriate regression models will be used. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.

Up to 12 months
Overall survival
Временное ограничение: Up to 12 months
Overall survival is defined as death due to any cause. Where possible, the specific cause of death should be documented, allowing the calculation of disease specific survival. Will be compared between the two groups at the 12-month time point. Descriptive analysis will be performed to analyze the nature of the data. Survival analysis like the Kaplan-Meier statistics will be used to find the overall survival in each arm. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.
Up to 12 months
Quality of life
Временное ограничение: Up to 12 months
Quality of life will be assessed using the EQ-5D-5L European Quality of Life Five Dimension Five Level scale or European Quality of Life Five Dimension Three Level Youth scale. Will be compared between the two groups. Descriptive analysis will be performed to analyze the nature of the data. Secondary outcomes with binary/multiple measures will be analyzed with logistic regression. For variables with continuous measure, appropriate regression models will be used. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.
Up to 12 months
Recovery following resection
Временное ограничение: Up to 12 months
After undergoing surgical resection for sarcomas of the extremity, participants are often left with an element of functional impairment in the affected limb due to the extent of the resection required. There are separate questionnaires for participants undergoing surgery on the upper and lower extremities, in which participants are asked to rate their ability to perform several tasks, rating them from 'impossible' to 'not at all difficult', as well as overall rating of how disabled they feel they are. Descriptive analysis will be performed to analyze the nature of the data. Secondary outcomes with binary/multiple measures will be analyzed with logistic regression. For variables with continuous measure, appropriate regression models will be used. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.
Up to 12 months
Surgical impact and decision making
Временное ограничение: Immediately following surgical resection
Immediately following the surgical procedure, a surgical case report form (CRF) will be completed by the surgeon who performed the surgery. This CRF will record if there was the potential for an acceptable close/positive margin due to the preservation of a critical structure, the length of the operation and any intra-operative complications. If the participant was randomized to the intervention arm, the CRF will also record whether the surgeon felt this influenced their operative decision making. Descriptive analysis will be performed to analyze the nature of the data. Secondary outcomes with binary/multiple measures will be analyzed with logistic regression. For variables with continuous measure, appropriate regression models will be used. Appropriate statistical tests depending on the nature of the variables (whether qualitative or quantitative) will be used for comparison between the two treatment arms.
