Studien-Informationen

Detailed Description:

Post-treatment STS surveillance is an integral element of patient care. Although earlier

detection of metastatic disease may improve long-term survival, no study has yet provided

definitive evidence to support this assumption. A thorough systematic review of the

literature has identified only a single limited randomized controlled trial (RCT) evaluating

this clinical question, and surveys of sarcoma surgeons have determined that surgeons

typically follow their patients based on the way in which they were trained. The orthopaedic

oncology field has identified sarcoma surveillance strategy as the top research priority in

the field. In order to fill the evidence gap in sarcoma surveillance, a large international

RCT is required. The investigators, therefore, propose the Surveillance AFter Extremity Tumor

surgerY (SAFETY) trial. In preparation for the SAFETY trial, the SAFETY investigators have

completed the following preparatory work: A) establishment of a worldwide research

collaborative group that spans 6 continents; B) collection of data from international sarcoma

patients to determine their perceptions of sarcoma surveillance and their willingness to

participate in a study in which randomization will determine their follow-up protocols; and

C) the organization of a large Protocol Development Meeting with international and

multidisciplinary participation, including sarcoma patient involvement, where critical

aspects of the protocol were discussed and finalized.

The international, multi-center SAFETY trial will determine the effect of surveillance

strategy on overall patient survival after surgery for a STS of the extremity by comparing

the effectiveness of both surveillance frequency (every 3 vs. every 6 months) and imaging

modality (CT scans vs. chest radiographs). Ultimately, the SAFETY trial will provide the

necessary evidence to develop evidence-based surveillance guidelines, and is poised to have a

significant impact on the post-operative care and outcomes of extremity soft-tissue sarcoma

patients.

Ein-/Ausschlusskriterien

Inclusion Criteria:

- The patient is 18 years of age or older;

- The patient has been diagnosed with a primary extremity grade II or III soft-tissue

sarcoma (STS);

- The patient has undergone surgical excision of the tumor with curative intent and with

no evidence of gross residual disease based on the pathology report;

- The patient has completed all planned neoadjuvant or adjuvant radiation and / or

chemotherapy, if applicable;

- The tumor size is greater than or equal to (≥) five centimeters according to the

pathology report or based on the pre-treatment MRI if neoadjuvant radiation and / or

chemotherapy are given; and

- The patient provides informed consent.

Exclusion Criteria:

- The patient has metastases at initial presentation based on the radiology report of

the initial thoracic imaging†;

- The patient has recently undergone surgical excision of a local recurrence;

- The patient has been diagnosed with one of the special sub-types, myxoid / round cell

liposarcoma or extra-skeletal Ewing's sarcoma*;

- The patient has been previously diagnosed with a genetic syndrome with an elevated

risk of malignancy, such as Li-Freumeni Syndrome‡;

- The patient has been previously diagnosed with a co-morbid condition that has a life

expectancy of less than (<) one year;

- The site-specific surveillance protocol for the patient's disease is not compatible

with the study protocol (i.e., regular planned whole-body imaging with positron

emission tomography [PET] scans);

- Likely problems, in the judgment of the investigator, with the patient maintaining

follow-up (with the specific reasoning requiring approval of the Methods Center);

- The patient is currently enrolled in a study that does not permit co-enrolment; and

- The patient has already been enrolled in the SAFETY trial.

- A second CT scan may be required to confirm that indeterminate nodules are false

positives before the patient can be enrolled (provided that the second CT scan

shows no evidence of metastatic disease);

- Myxoid liposarcoma and extra-skeletal Ewing's sarcoma have different

metastatic patterns, which necessitate different surveillance protocols;

- Individuals with Li-Freumeni Syndrome, or other genetic syndromes with

an elevated risk of malignancy, appear to be at an elevated risk for

radiation-induced cancers, so the use of CT scans should be limited.

Studien-Rationale

Primary outcome:

1. Overall Survival (Time Frame - 5 years):
as measured by death from any cause.



Secondary outcome:

1. Patient Anxiety (Time Frame - 5 years):
The PROMIS® Cancer-Anxiety instrument assesses self-reported fear (fearfulness, panic), anxious misery (worry, dread), hyperarousal (tension, nervousness, restlessness), and somatic symptoms related to arousal (racing heart, dizziness). The PROMIS® Cancer-Anxiety instrument is a computer adaptive test. A minimum of 4 questions must be answered. One's responses will guide the system's choice of the next question. The test will continue until either the standard error drops below a specified level or the participant has answered the maximum number of 12 questions (whichever comes first). Each question has 5 response options ranging in value from 1 to 5. To find the raw score, sum the values of the response to each question. The lowest possible raw score is 4 and the highest is 60. The raw score will then be converted into a standardized T-score for each participant using the applicable conversion table. A higher T-score represents a higher degree of anxiety.

2. Patient Satisfaction (Time Frame - 5 years):
The PROMIS® Satisfaction with Social Roles & Activities instrument assesses satisfaction with performing one's usual social roles and activities (e.g., 'I am satisfied with my ability to participate in family activities'). This instrument is a computer adaptive test. A minimum of 4 questions must be answered. One's response will guide the system's choice of the next question. The test will continue until either the standard error drops below a specified level or the participant has answered the maximum number of 12 questions (whichever comes first). Each question has 5 response options ranging in value from 1 to 5. To find the raw score, sum the values of the response to each question. The lowest possible raw score is 4 and the highest possible raw score is 60. The raw score will then be converted into a standardized T-score for each participant using the applicable conversion table. A higher T-score represents a higher degree of satisfaction.

3. Patient Quality-of-Life (Time Frame - 5 years):
The validated EuroQol-5 Dimension 5-level (EQ-5D-5L) questionnaire measures generic health status and consists of 2 sections: the descriptive system and the Visual Analogue Scale (VAS). The descriptive system is comprised of 5 dimensions (mobility, self care, usual activities, pain / discomfort and anxiety / depression). Each question has 5 response options ranging in value from 1 to 5. To find the raw score, sum the values of the response to each question. The lowest possible raw score is 5 and the highest is 25. A lower raw score in the descriptive system represents fewer issues with each of the 5 domains. The VAS records a participant's self-rated health from 0 to 100 on a vertical VAS with endpoints labeled '100 - the best health you can imagine' and '0 - the worst health you can imagine'. The participant is asked to mark an 'X' on the scale and write the corresponding number, which is this section's raw score.

4. Local Recurrence-Free Survival (Time Frame - 5 years):
As measured by the length of time from the time of randomization that the participant survives with no detection of recurrent disease at the initial tumor site or operative field.

5. Metastasis-Free Survival (Time Frame - 5 years):
As measured by as the length of time from the time of randomization that the participant survives with no detection of systemic disease recurrence at any anatomic location.

6. Treatment-Related Complications (Time Frame - 5 years):
Will include both chemotherapy-related complications, such as febrile neutropenia, fungal infections or sepsis, and thoracotomy-related complications, such as pneumothorax or surgical site infections.

7. Net Healthcare Costs (Time Frame - 5 years):
Will include both the net costs of surveillance and costs incurred from metastasis treatment and metastasis treatment-related complications.
