Plain English Summary

Background and study aims
Soft Tissue Sarcoma (STS) is a condition in which cancer cells form in the soft tissues of the body, such as the muscles, tendons (bands of tissue that connect muscles to bones), fat and blood vessels. STS most commonly affects tissue in the arms, legs and trunk (torso). In most cases, the first treatment used to treat STS is surgically removing the tumour. This can be done in combination with radiotherapy (using high-energy radiation beams to destroy cancer cells) or chemotherapy (anti-cancer drugs). The aim of this study is to look at the medical records of people who were diagnosed with STS and were treated surgically to see if outcomes are better for those who also had radiotherapy.

Who can participate?
Adults who have been diagnosed with STS between 2008 and 2012

What does the study involve?
Participating centres are asked to prepare a list of patients with STS who were diagnosed between 2008 and 2012. Patients would have been treated with surgery alone, surgery and radiotherapy, surgery and chemotherapy, surgery and chemo-radiation (a combination of radiotherapy and chemotherapy), or surgery and isolated limb perfusion (a type of chemotherapy injected directly into the affected limb) Information from patient charts is then collected in order to find out what treatment the participants had and whether it has been successful.

What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating.

Where is the study run from?
1. Istituto Oncologico Veneto (Italy)
2. The Royal Marsden NHS Foundation Trust (UK)

Study information

Scientific title

Multicenter retrospective observational chart review on treatment management of soft tissue sarcoma patients treated by surgery with or without perioperative treatment



Study hypothesis

The primary objective of this chart review is to investigate the prognostic significance of pathological complete response (pathCR*) to a pre-operative treatment in patients with STS of trunk and extremities on Disease Free Survival (DFS**) at three years.

*PathCR is defined as greater than or equal to 95% necrosis/fibrosis or less than or equal to 5% viable cells
**DFS is defined as time between diagnosis, and local or distant relapse of the disease or occurrence of any cancer or death

Ethics approval

This is a non interventional retrospective review of patient individual charts which does not need ethical approval. In the UK, the Ethics Committee of the Royal Marsden Foundation will review the study.

Patient information sheet

No participant information sheet available


Malignant soft tissue sarcoma


Each center will be asked to prepare a list of eligible patients based on inclusion and exclusion criteria. If no database of soft tissue sarcoma (STS) patients is available, the institution data manager will be asked to prepare a list of all patients newly diagnosed between 2008 and 2012 with STS. From this list a selection of eligible patients should be performed according to inclusion and exclusion criteria.

All data are collected retrospectively. The charts are reviewed once and treatment data are collected in a eCRF. Patients must have been treated between 2008 and 2012 and followed up for 3 years, data of the treatment procedure and the follow up visits are collected at one time point.

Intervention type



Drug names

Primary outcome measure

Disease free survival is measured through medical record review 3 years after disease diagnosis.

Secondary outcome measures

1. Pathological response (% of necrosis, % of fibrosis, % of viable cells) is measured through review of the pathological report of the surgical specimen at the time of surgery
2. Tumor type and subtype is assessed through pathological report review at diagnosis and the time of surgery
3. Chemotherapy treatment (drug name, drug dose, treatment duration, number of cycles) is assessed by reviewing drug prescription form at each course of chemotherapy and at the end of chemotherapy treatment
4. Radiation treatment (Dose delivered, treatment duration) is assessed by reviewing medical radiation report at the end of Radiation treatment
5. Surgical procedure (conservative surgery, amputation, R0 resection, R2 resection) is assessed by reviewing the medical surgery report at the time of surgery
6. Quality of surgery (R0 resection, R1 resection, surgical margin, tumor size) is measured by reviewing pathological reports at the date of surgery
7. New tumors (local recurrence, distant recurrence, other cancer) are assessed by reviewing medical report and radiological MRI and CT scan report on the date of surgery, 6 months after surgery, 12 months after surgery, 18 months after surgery, 24 months after surgery, 30 months after surgery, 36 months after surgery
8. Quality of life (Performans status, walking distance, presence at work) is measured by reviewing medical reports on the date of diagnosis of the tumor, date of surgery, 6 months after surgery, 12 months after surgery, 18 months after surgery, 24 months after surgery, 30 months after surgery, 36 months after surgery
