Overall survival in patients with re-excision of positive microscopic margins of limb and trunk wall soft tissue sarcoma operated outside of a reference center: a nationwide cohort analysis.

Background: This French nationwide NETSARC exhaustive prospective cohort aims to explore the impact of systematic re-excision (RE) as adjuvant care on overall survival (OS), local recurrence free survival (LRFS), and local and distant control (RFS) in patients with soft tissue sarcoma (STS) with positive microscopic margins (R1) after initial resection performed outside of a reference center.

Methods: Eligible patients had experienced STS surgery outside a reference center from 2010 to 2017, and had R1 margins after initial surgery. Characteristics and treatment comparisons used chi-square for categorical variables and Kruskall-Wallis test for continuous data.

[Preoperative breast imaging review: Interests and limits of specialized validation in oncology].

Objectives: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients.

Materials And Methods: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images.

Watch and Wait Approach for Re-excision After Unplanned Yet Macroscopically Complete Excision of Extremity and Superficial Truncal Soft Tissue Sarcoma is Safe and Does Not Affect Metastatic Risk or Amputation Rate.

Background: The benefits of systematic re-excision (RE) after initial unplanned excision (UE) of soft tissue sarcoma (STS) are unknown.

Objective: The aim of this study was to evaluate the impact of delayed RE versus systematic RE after UE on overall survival (OS), metastatic relapse-free survival (MRFS), local relapse-free survival (LRFS), and rate of amputation.

Methods: Patients who underwent complete UE, without metastasis or residual disease, for primary extremity or superficial STS between 2007 and 2013 were analyzed.

One-bloc percutaneous large biopsy of soft-tissue tumours: feasibility study and possible indications.

Aim: To report the early results of the Intact lesion excision system (LES) regarding feasibility, tolerance and efficiency in obtaining soft-tissue tumour samples under ultrasound guidance.

Materials And Methods: The feasibility and tolerance of Intact LES procedures under ultrasound guidance were studied prospectively in 15 patients. The procedure was performed on an outpatient basis under local anaesthesia by a single interventional radiologist with 6 years of experience and lasted around 30 min.
