Several regional therapies are used for the local treatment of patients with soft tissue sarcomas (STS), especially for tumors at high risk for local recurrence. Surgery with negative tumor resection margins is the main treatment for primary STS. External-beam radiation therapy is considered for deeply seated, large, and high-grade disease to lower the risk of local recurrence. A combination of preoperative chemo-radiation is associated with improved local control. TNF-α-based isolated limb perfusion is another regional chemotherapy strategy available at specialized surgical oncology units for unresectable STS. Other strategies suitable for management of advanced STS include cryoablation and radiofrequency. This review discusses these and other current regional treatment strategies.  This review contains 10 figures, 6 tables and 64 references Key words: cryoablation, extremity, hyperthermia, isolated limb perfusion, limb infusion, radiotherapy, regional therapy, sarcoma

Male Predominance

Epithelioid sarcoma is a rare high-grade malignancy identified by Enzinger in 1970. It accounts for 1% of all reported soft tissue sarcomas and presents most commonly in distal upper extremities in young adults with a male predominance. At this time, there are only 5 previously reported cases of primary epithelioid sarcoma of the orbit. We present a primary orbital epithelioid sarcoma case of a patient who underwent orbital exenteration followed by external beam radiation treatment. Because the literature is limited, this is to our knowledge the largest descriptive analysis of cases of orbital epithelioid sarcoma. We also provide a detailed review of all the previously reported primary orbital epithelioid sarcoma cases, as well as a discussion on the use of postoperative radiation therapy for patients with epithelioid sarcoma. Surgical resection followed by adjuvant radiation therapy appears to be a safe option for local treatment of this rare malignancy, but further future studies are needed of this rare clinical situation in order to better understand and optimize treatment for patients with orbital epithelioid sarcoma.

OBJECTIVEThe objective of this study was to present the results of a consecutive series of 120 cases treated with spinal laser interstitial thermal therapy (sLITT) to manage epidural spinal cord compression (ESCC) from metastatic tumors.METHODSThe electronic records of patients treated from 2013 to 2019 were analyzed retrospectively. Data collected included demographic, pathology, clinical, operative, and imaging findings; degree of epidural compression before and after sLITT; length of hospital stay; complications; and duration before subsequent oncological treatment. Independent-sample t-tests were used to compare means between pre- and post-sLITT treatments. Survival was estimated by the Kaplan-Meier method. Multivariate logistic regression was used to analyze predictive factors for local recurrence and neurological complications.RESULTSThere were 110 patients who underwent 120 sLITT procedures. Spinal levels treated included 5 cervical, 8 lumbar, and 107 thoracic. The pre-sLITT Frankel grades were E (91.7%), D (6.7%), and C (1.7%). The preoperative ESCC grade was 1c or higher in 92% of cases. Metastases were most common from renal cell carcinoma (39%), followed by non–small cell lung carcinoma (10.8%) and other tumors (35%). The most common location of ESCC was in the vertebral body (88.3%), followed by paraspinal/foraminal (7.5%) and posterior elements (4.2%). Adjuvant radiotherapy (spinal stereotactic radiosurgery or conventional external beam radiation therapy) was performed in 87 cases (72.5%), whereas 33 procedures (27.5%) were performed as salvage after radiotherapy options were exhausted. sLITT was performed without need for spinal stabilization in 87 cases (72.5%). Post-sLITT Frankel grades were E (85%), D (10%), C (4.2%), and B (0.8%); treatment was associated with a median decrease of 2 ESCC grades. The local control rate at 1 year was 81.7%. Local control failure occurred in 25 cases (20.8%). The median progression-free survival was not reached, and overall survival was 14 months. Tumor location in the paraspinal region and salvage treatment were independent predictors of local recurrence, with hazard ratios of 6.3 and 3.3, respectively (p = 0.01). Complications were observed in 22 cases (18.3%). sLITT procedures performed in the lumbar and cervical spine had hazard ratios for neurological complications of 15.4 and 17.1 (p < 0.01), respectively, relative to the thoracic spine.CONCLUSIONSsLITT is safe and provides effective local control for high-grade ESCC from vertebral metastases in the thoracic spine, particularly when combined with adjuvant radiotherapy. The authors propose considering sLITT as an alternative to open surgery in selected patients with spinal metastases.

Extremity sarcomas are a heterogeneous group of malignant tumors with a varied propensity for local recurrence. This review focuses on factors associated with local recurrence and survival, diagnostic workup, management, outcomes, and surveillance. Local recurrence is more common in patients with previous local recurrence, positive margins, high-grade histology, and deep tumors. In the absence of metastases, the mainstay of treatment is limb-sparing surgery, with radiation to improve local control. Modalities such as brachytherapy or proton therapy may be valuable in the setting of previous irradiation. Systemic chemotherapy is typically limited to the treatment of distant disease, although chemotherapy can be delivered locally via limb perfusion or infusion for locally advanced or recurrent disease. Amputation is used if local control cannot be achieved while preserving adequate limb function or as a palliative option for pain, bleeding, or fungating tumors. Prognostic factors associated with poor survival include tumors that recur with high-grade histology, with a large size (> 5 cm), or within a short interval (< 16 months). Reports of 5-year overall survival in patients with locally recurrent sarcomas vary from 36 to 65%. Surveillance includes physical examination, cross-sectional imaging, and chest x-ray. Genetic profiling and intratumoral injections provide novel therapeutic targets. This review contains 1 figure, 4 tables and 40 references.   Key words: chemotherapy, hyperthermic isolated limb perfusion, intratumoral injection, isolated limb perfusion, local recurrence, margin status, radiation, soft tissue sarcoma, wide local excision
