BACKGROUND: To compare the survival outcomes and late toxicities of postoperative intensity-modulated radiation therapy (IMRT) with two-dimensional radiotherapy (2D-RT) for patients with soft tissue sarcoma (STS) of extremities and trunk. METHODS: 274 consecutive patients with nonmetastatic STS of extremities and trunk treated with postoperative IMRT (n = 187) and 2D-RT (n = 87) were analyzed. Survival was calculated by using Kaplan-Meier method. Independent prognostic factors were identified using Cox stepwise regression analysis for variables with a P-value <0...

BACKGROUND: Combining stereotactic radiosurgery (SRS) and active systemic therapies (STs) achieved favourable survival outcomes in patients with melanoma brain metastases (MBMs) in retrospective analyses. However, several aspects of this treatment strategy remain poorly understood. We report on the overall survival (OS) of patients with MBM treated with a combination of radiotherapy (RT) and ST as well as the impact of the v-Raf murine sarcoma viral oncogene homolog B (BRAF)-V600 mutation (BRAFmut) status, types of RT and ST and their sequence...

Currently considered a variant of Ewing sarcoma, adamantinoma-like Ewing sarcoma is a rare malignancy that shows classic Ewing sarcoma-associated gene fusions but also epithelial differentiation. Here we present the 6th reported case of adamantinoma-like Ewing sarcoma involving the thyroid gland. Sections of the thyroid tumor from a 20-year old woman showed sheets, lobules and trabeculae of primitive, uniform, small round blue cells that diffusely expressed pankeratin, p40 and CD99. Fluorescent in situ hybridization revealed an EWSR1 gene rearrangement and an EWSR1-FLI1 fusion was detected by RT-PCR...

Background  Cahan's criteria have been utilized since 1948 to establish causality between prior radiation treatment and the development of secondary malignancy. One major criterion specifies that histological and radiographic evidence collected before and after radiation treatment must confirm separate tumor types; however, pretreatment biopsy is rarely obtained prior to radiosurgery for vestibular schwannoma and many other skull base and cranial lesions. Therefore, in these cases Cahan's criteria cannot be validly applied...

Angiosarcomas are mesenchymal neoplasms of vascular origin that represent approximately 2% of soft tissue sarcomas. We discuss the case of a 75-year-old female who had presented with a purple nodular rash along the bilateral nasolabial folds. Upon further work-up, she was diagnosed with angiosarcoma, with the confirmed involvement of multi-focal sites. These included biopsy proven sites of the face and duodenum along with the radiographic involvement of the lungs, liver, and osseous tissue. We report this unique presentation of a rare malignancy and the treatment course with radiation, paclitaxel, and bevacizumab...

Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare cancer of dendritic cell origin that lacks a standardized treatment approach. Here, we performed genomic characterization of metastatic IDCS through whole exome sequencing (WES) of tumor tissues procured from a patient who underwent research autopsy. WES was also performed on a treatment-naïve tumor biopsy sample obtained from prior surgical resection. Our analyses revealed ultra-hypermutation, defined as >100 mutations per megabase, in this patient's cancer, which was further characterized by the presence of three distinct mutational signatures including UV radiation and APOBEC signatures...

BACKGROUND: Olaratumab (LY3012207/IMC-3G3/Lartruvo™) is a fully human monoclonal antibody specific for platelet-derived growth factor receptor alpha (PDGFRα). Phase Ib/II trial results of olaratumab plus doxorubicin in adult patients with advanced soft tissue sarcoma (STS) supported accelerated FDA approval of this regimen. Radiation therapy (RT) is frequently used for high-risk localized STS. However, olaratumab has not been tested with concurrent RT. Here, we evaluate the chimeric anti-mouse PDGFRα antibody 1E10Fc as a radiosensitizer in a primary mouse model of STS...

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma accounting for 5-8% of malignant tumours in children and adolescents. Children with high risk disease have poor prognosis. Anti-RMS therapies include surgery, radiation and combination chemotherapy. While these strategies improved survival rates, they have plateaued since 1990s as drugs that target differentiation and self-renewal of tumours cells have not been identified. Moreover, prevailing treatments are aggressive with drug resistance and metastasis causing failure of several treatment regimes...

Approximately half of all cancer patients receive radiation therapy as part of their oncologic treatment. Radiation-associated sarcomas occur in fewer than 1% of patients who receive radiation therapy but account for up to 5% of all sarcomas. As the use of radiation has increased in the past few decades and overall oncologic outcomes are improving, the incidence of radiation-associated sarcomas is also expected to increase. Historically, radiation-associated sarcomas have been associated with poor outcomes but recent data suggest the prognosis is improving...

Advances in computed tomography (CT) hardware have propelled the development of novel CT contrast agents. In particular, the spectral capabilities of X-ray CT can facilitate simultaneous imaging of multiple contrast agents. This approach is particularly useful for functional imaging of solid tumors by simultaneous visualization of multiple targets or architectural features that govern cancer development and progression. Nanoparticles are a promising platform for contrast agent development. While several novel imaging moieties based on high atomic number elements are being explored, iodine (I) and gadolinium (Gd) are particularly attractive because of their existing approval for clinical use...

PURPOSE: Radiation-associated sarcomas (RAS) are considered to have a poor prognosis. While the incidence is anticipated to rise, contemporary data regarding predictors of outcomes are few. We performed a retrospective analysis to identify RAS prognostic factors, as well as subset analyses for radiation-associated angiosarcoma arising after treatment for breast cancer (RAAB) and other RAS subtypes (other-RAS). METHODS AND MATERIALS: Patients with localized RAS evaluated at an institutional multidisciplinary sarcoma clinic were identified...

Radiation is a treatment for many gynecological malignancies, especially locally advanced cervical cancer. Development of sarcoma due to previous radiation occurs very rarely. They develop within the radiation field. We report a case of carcinosarcoma in our patient developed 8 years after the radiotherapy (RT) that she received in the form of external beam radiation and intracavitary RT along with concomitant chemotherapy consisting of cisplatin. Although the development of secondary primary cancer is rare, for every patient who receives radiation for treatment of cancer, close follow-up is recommended as they may have viable endometrium...

BACKGROUND: Fever of unknown origin is often a diagnostic dilemma for clinicians due to its extremely broad differential. One of the rarer categories of disease causing fever of unknown origin is malignancies; of these, soft tissue sarcoma is one of the least common. Soft tissue sarcomas make up < 1% of all adult malignancies and often do not present with any systemic manifestations or neoplastic fevers.

REVIEW
Megan Meyer, Mahesh Seetharam
Soft tissue sarcomas are rare cancers with an expected incidence of about 14,000 new cases in 2018, and account for less than 1% of all cancers. It includes in excess of 75 heterogeneous subtypes with varying biology, molecular aberrations, and variable response to treatment. Because of the rarity of these tumors and the many different subtypes, there is no large-scale data to guide treatment, and hence the need for a multidisciplinary individualized approach to treatment, preferably at a high-volume tertiary referral center...

Radiation-associated sarcomas are rare and aggressive types of sarcomas that can occur after exposure to ionizing radiation. We examine a case of radiation-associated undifferentiated/unclassified soft-tissue sarcoma with primary disease in the chest wall. The optimal treatment of these patients is surgical resection if possible; however, the role of chemotherapy has not been well defined. The patient described herein had a central tumor in the chest wall. Since many of these patients have borderline resectable tumors, the use of neoadjuvant chemotherapy may be helpful to downstage the tumors for possible surgical resection...
