Special Issue Information

Dear Colleagues,

There is no current literature consensus regarding the optimal diagnostic and treatment approach to soft tissue sarcomas (STSs). Recent publications highlighted new biological aspects and deeper genetic characterization of different types of STS, up-to-date research works focused on a highly personalized medicine approach to the treatment of STS, and modern imaging techniques (e.g. PET-MRI).

In the past decade, the use of neoadjuvant and adjuvant chemotherapy, new developed immunotherapies, combined Hyperthermia with chemo-irradiation, and advances in radiation therapy techniques, like Stereotactic Body Radiation Therapy (SBRT) or the use of Artificial Intelligence to detect radio-sensitive areas of the STS, were studied but conclusive results are still debated.

The growing importance of a multidisciplinary approach of joint surgical and medical treatment of STS, involving an orthopedic surgeon, radiologist, pathologist, vascular, general, and plastic surgeon, medical oncologist, and radiation oncologist, is becoming more prominent.

The aim of the Special issue Is to provide readers with a full comprehensive data collection on up-to-date studies and treatments for defining shared guidelines and obtaining a consensus in approaches to STS.

The following types of submissions will be considered: original studies, meta-analysis and systematic reviews, clinical trial studies.

Background: There is an ongoing debate about the role of perioperative chemotherapy in retroperitoneal sarcoma (RPS). The aim of this study was to evaluate the effectiveness of perioperative chemotherapy in subtypes of RPS that are considered chemosensitive, including retroperitoneal angiosarcoma, undifferentiated pleomorphic sarcoma, myxoid liposarcoma, spindle cell sarcoma, and synovial sarcoma. Methods: This is a population-based retrospective cohort study. Patients with localized retroperitoneal sarcoma who underwent surgery were included from the US National Cancer Database (NCDB). After propensity score matching for the factors age, sex, grade, margin status, and tumor size, multivariable logistic and Cox regression analyses were used to identify factors associated with systemic therapy and their potential impact on the survival of patients with localized RPS. Results: We included 851 patients who underwent surgery between 2004 and 2020 (85% white, 41% female, and mean age 62 years). Of those, 227 patients (26.7%) received perioperative chemotherapy. In multivariable logistic regression, age ≤ 60 and tumor grading GIII/IV vs. GI/II were associated with a higher probability of receiving perioperative chemotherapy. After propensity score matching, we detected no difference in overall survival between patients who received chemotherapy and those who did not (HR 0.89, CI 0.55–1.43; and log-rank p = 0.92). Patient age ≤80 and tumor grading GI/II vs. GIII/IV were associated with improved overall survival. Conclusions: In this large analysis, the use of perioperative chemotherapy was not associated with improved survival in rare, chemosensitive subtypes of retroperitoneal sarcoma. However, selection bias must be considered when interpreting these findings. Full article

Objectives: To evaluate the clinical heterogeneity of sarcomas by examining associations between histological subtypes, metastatic patterns, treatment modalities, and survival outcomes. Methods: We analyzed data from 97,062 adult patients diagnosed with sarcoma between 2000 and 2020, using the Surveillance, Epidemiology, and End Results (SEER) database. Fourteen histological subtypes were included. Propensity score matching (PSM) was employed to adjust for baseline differences, and Cox proportional hazards models were used to identify prognostic variables. Results: The most prevalent subtypes were sarcoma not otherwise specified (31.9%), leiomyosarcoma (17.1%), and liposarcoma (13.9%). Metastatic patterns differed significantly by subtype; liver metastases were most common in sarcomas with small blue round cell (SBRC) features (8.9%) and stromal sarcoma (6.1%), while lung metastases were frequently observed in Ewing sarcoma (10.0%) and rhabdomyosarcoma (9.7%). Median overall survival (mOS) varied widely, ranging from 234 months in chondrosarcoma to 16–20 months in rhabdomyosarcoma and SBRC sarcoma. Overall, patients with primary sarcoma had significantly better survival than those with treatment-related disease (119.0 vs. 45.0 months, p < 0.0001), with this trend consistent across most subtypes. Treatment responses were subtype- and size-dependent. For instance, surgery plus radiotherapy improved outcomes in giant cell sarcoma regardless of tumor size, whereas chemotherapy provided benefit only in tumors larger than 5 cm. Combined surgery and radiotherapy offered additional survival benefit in select subtypes, including chordoma, leiomyosarcoma (>5 cm), and synovial sarcoma (<5 cm). Conclusions: Sarcomas exhibit substantial clinical and prognostic heterogeneity across histological subtypes. These findings underscore the importance of subtype-specific, individualized treatment strategies in optimizing patient outcomes. Full article

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm that is characterized by a proliferation of myofibroblastic and fibroblastic spindle cells, accompanied by an inflammatory infiltrate that is abundant in plasma cells, lymphocytes, and eosinophils. IMT can arise in various anatomical locations but most commonly occurs in the abdominal cavity, retroperitoneum, and lung, particularly in children and young adults. IMT typically demonstrates local invasion or recurrence, whereas metastasis is rare. IMTs pose a diagnostic challenge because of their overlapping morphological characteristics with a heterogeneous group of nonneoplastic and neoplastic lesions. Precise diagnosis is crucial for optimal management and accurate prognostication. Despite recent advancements in IMT diagnosis and treatment, its biological complexity and clinical management remain challenging due to significant histological heterogeneity and molecular genetic diversity. This review provides comprehensive updates on the clinical, molecular, and pathological characteristics of IMT, highlighting the diagnostic approaches and key differential diagnoses. Full article
