Conditions

Resectable Soft Tissue Sarcoma, Stage IA Soft Tissue Sarcoma of the Trunk and Extremities AJCC v8, Stage IB Soft Tissue Sarcoma of the Trunk and Extremities AJCC v8, Stage II Soft Tissue Sarcoma of the Trunk and Extremities AJCC v8, Stage I Soft Tissue Sarcoma of the Trunk and Extremities AJCC v8

Brief summary

This phase II trial investigates the effects of hypofractionated radiation therapy before surgery on wound complications associated with surgery in treating patients with soft tissue sarcoma of the extremity (arms, hands, legs or feet) and superficial trunk that has not spread to other parts of the body (localized) and can be removed by surgery (resectable). Hypofractionated is a shorter radiation therapy treatment length (fewer radiation treatment days) and administers the total radiation dose as larger daily doses, compared to conventionally fractionated therapy.

Detailed description

PRIMARY OBJECTIVE: I. To report the major acute wound complication rate associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. SECONDARY OBJECTIVES: I. To report the 5-year local failure rate associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. II. To report the 5-year disease-free survival rate associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. III. To report the 5-year overall survival rate associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. IV. To report long-term toxicity rates associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. V. To describe patterns of relapse associated with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. VI. To describe patient reported outcomes/quality-of-life outcomes with hypofractionated preoperative radiation therapy, 42.75 Gy in 15 fractions. OUTLINE: Patients undergo hypofractionated radiation therapy once daily (QD) (except weekends and holidays) over 3 weeks for a total of 15 fractions. Within 3-6 weeks after completion of radiation therapy, patients undergo surgical resection. After completion of study treatment, patients are followed up at 4-8 weeks, every 3-4 months for years 1-2, and every 6 months for years 3-5.

Inclusion criteria

* Newly diagnosed, histological confirmation of soft tissue sarcoma of the extremities (including limb girdle) or superficial trunk that present as either - * Deemed a candidate for complete macroscopic resection of the primary sarcoma OR * Having had non-oncologic excisional procedure with positive or uncertain resection margins and still be eligible if the evaluating sarcoma surgeon recommends oncologic re-resection of the surgical bed to obtain negative margins after a course of preoperative radiation therapy * No evidence of nodal or distant metastases as determined by clinical examination on any form of imaging * Eastern Cooperative Oncology Group (ECOG) performance status (PS) =\< 3 * Life expectancy greater than 6 months * Patients capable of childbearing must use adequate contraception * Ability to complete questionnaire(s) by themselves or with assistance * Ability to provide written informed consent * Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)

Exclusion criteria

* Previous radiation therapy to the site of the sarcoma or area surrounding it such that it would be encompassed by the radiation field needed to treat the current sarcoma. In other words, treatment on this trial would require re-irradiation of tissues * Patients with nodal or distant metastases * Rhabdomyosarcoma, soft tissue osteosarcoma, soft tissue Ewing sarcoma, and benign histologies * Any of the following: * Pregnant women * Nursing women * Men or women of childbearing potential who are unwilling to employ adequate contraception

Design outcomes

Primary

MeasureTime frameDescription
Major Wound ComplicationsWithin 120 days of surgical resection of soft tissue sarcoma following preoperative radiation therapyWill be assessed by the number of patients who experience major wound complications within 120 days following surgery. Major wound complication is defined as secondary unplanned operation under general or regional anesthesia for wound repair (e.g., debridement, operative drainage, or secondary wound closure including rotationplasty, free flaps or skin grafts); or wound management without secondary operation including invasive procedures (e.g., aspiration of seroma or readmission for wound care such as intravenous antibiotics or persistent deep packing for 120 days or longer).

Secondary

MeasureTime frameDescription
Local Failure RateUp to 1 yearDefined as any radiographic or pathologic evidence of recurrent disease inside the clinical target volume (CTV) and/ or to within 3 cm from the edge of the CTV. Local failure rate at 5 years (LFR5) will be evaluated by the number of patients free of local failure/recurrence at 5 years.
Percent Probability of Disease-free Survival at 1 Yearup to 1 yearDefined as the time from registration to the earliest date of documentation of local recurrence, regional recurrence, distant recurrence, or death due to any cause
Percent Probability of Overall Survival at 1 YearUp to 1 yearDefined as the time from registration date to death due to any cause
Incidence of Late Adverse EventsBetween 3 months and 24 months after completion of hypofractionated preoperative radiation therapyThe descriptions and grading scales found in the revised National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be utilized for adverse event reporting. The rate of \>= grade 2 late adverse events will be estimated by the number of patients with a \>= grade 2 late adverse events.
Pattern of RelapseUp to 1 yearsPattern of relapse will be evaluated by number of patients with patterns of tumor recurrence such as local recurrence, marginal recurrence, regional recurrence, distant metastasis, and second primary tumor.
Incidence of Adverse EventsUp to 1 yearThe descriptions and grading scales found in the revised NCI CTCAE version 5.0 will be utilized for adverse event reporting. The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns.
Change in Quality of Life - PROMIS-10Baseline up to 24 months post-surgeryResults from the ten-item Patient Reported Outcomes Measurement Information System (PROMIS-10) questionnaire will be used to evaluate physical and mental health separately. The PROMIS-10 consists of ten items that measure physical health, physical functioning, general mental health, emotional distress, satisfaction with social activities and relationships, ability to carry out usual social activities and roles, pain, fatigue and overall quality of life.
Change in Quality of Life - TESSBaseline up to 24 months post-surgeryResults from the Toronto Extremity Salvage Score (TESS) questionnaire will be used to evaluate functional outcomes. The TESS was designed as a measure of the difficulty patients have performing routine daily activities. It consists of 31 items with responses from 1 (impossible to do) to 5 (not at all difficult).

Outcome results

Primary

Major Wound Complications

Major wound complication is defined as secondary unplanned operation under general or regional anesthesia for wound repair (e.g., debridement, operative drainage, or secondary wound closure including rotationplasty, free flaps or skin grafts); or wound management without secondary operation including invasive procedures (e.g., aspiration of seroma or readmission for wound care such as intravenous antibiotics or persistent deep packing for 120 days or longer).

Time frame: Within 120 days of surgical resection of soft tissue sarcoma following preoperative radiation therapy

Population: Two patients treated with radiation therapy came off study before surgery because of death.
