BACKGROUND: Modifiable risk factors that can be optimized to minimize postoperative complications in patients with bone sarcomas are yet to be identified. METHODS: We retrospectively identified 275 patients aged 18 and older who underwent surgery for primary bone sarcomas who also had albumin values recorded within 4 weeks before surgery. Postoperative complications were defined as infection, hematoma, need for additional surgery, or wound complications. RESULTS: In the multivariate analysis, age (P = 0...

Ewing Sarcoma is a highly lethal undifferentiated tumor of bone. ES is a small round cell tumor with etiological and characteristic chromosomal translocations between TET/FET (TLS/FUS, EWSR1, and TAF15) and ETS (E26 transformation-specific) family genes. Generally, therapeutic approach for metastatic Ewing Sarcoma includes both local (surgery and radiotherapy) and systemic (chemotherapy) disease control with an overall cure rate of 20%. For extra-osseous tumors, the most common primary sites of disease are trunk, extremities, head and neck, retroperitoneum...

Angiosarcoma is a rare soft tissue neoplasm, which accounts for <1% of all soft tissue tumours. It has been previously reported that the incidence rate of angiosarcomas increases following radiotherapy. The present study reports two cases of intra-abdominal angiosarcoma associated with previous radiotherapy treatment. To the best of our knowledge, these associations have not been previously described in English literature. The patients aged 71 and 83 years were admitted to the center for abdominal pain and diarrhea...

Precision radiotherapy, which accurately delivers the dose on a tumor and confers little or no irradiation to the surrounding normal tissue and organs, results in maximum tumor control and decreases the toxicity to the utmost extent. Proton beam therapy (PBT) provides superior dose distributions and has a dosimetric advantage over photon beam therapy. Initially, the clinical practice and study of proton beam therapy focused on ocular tumor, skull base, paraspinal tumors (chondrosarcoma and chordoma), and unresectable sarcomas, which responded poorly when treated with photon radiotherapy...

Malignant tumors found in children are different from the ones that occur in adults. Compared to the malignancies in adults, the histological entities in pediatric patients are different and survival rates are higher among the children. Though pediatric soft tissue sarcomas are less common than leukemia and central nervous system malignancies, recognition of them is necessary to start the therapy as soon as possible. The delay of an appropriate treatment - chemotherapy, radiotherapy, surgery, in some cases targeted therapy - is unfavorable because somatic damages and functional loss can occur...

Resection of the inferior vena cava (IVC) for malignancy is a technically demanding procedure. We present a series of six cases of resection of the IVC for retroperitoneal sarcomas, four of which were primary caval tumors. We outline the technical difficulties faced in these complex procedures and discuss the oncological outcomes of these rare tumors. We performed a retrospective review of six patients operated for retroperitoneal masses involving the inferior vena cava between April 2015 and July 2016 at our tertiary care institute...

PURPOSE OF REVIEW: The advent of proton beam therapy (PBT) has initiated a paradigm shift in the field of pediatric radiation oncology, with increasing promise to alleviate both short-term and long-term toxicities. Given the dramatic rise in proton therapy centers in the United States, a discussion of the quality of evidence supporting its use in pediatric cancers is warranted. RECENT FINDINGS: Proton radiotherapy appears to decrease the incidence and severity of late effects with the strongest evidence in pediatric brain tumor cohorts that shows benefits in neurocognitive, hearing, and endocrine outcomes...

INTRODUCTION: The treatment for soft tissue sarcomas has evolved to include radiotherapy, wide local excision and plastic surgical reconstruction. Goals for the reconstruction of these irradiated defects are the introduction of non-irradiated healthy tissue, tension-free closure and obliteration of potential dead space. Although many defects once required free tissue transfer for reconstruction, greater knowledge of anatomical vascular pattern has led to the increasing use of propeller perforator flaps, islanded and transposed into the defect...

Myeloid sarcoma (MS) of the breast is uncommon. We report this case of a 29-year-old female presented with a breast lump that was diagnosed as hamartoma by radiology. The lump was removed surgically. Pathological examination revealed a malignant tumor composed of immature cells with eosinophilic cytoplasm and single or multiple nucleoli, diffusely infiltrating the mammary parenchyma and sparing a few ducts and lobules. Immunostaining revealed positivity for leukocytic common antigen, myeloperoxidase, and CD68, and focally positive for CD34 and CD117...

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood with an unmet clinical need for decades. A single oncogenic fusion gene is associated with treatment resistance and a 40 to 45% decrease in overall survival. We previously showed that expression of this PAX3:FOXO1 fusion oncogene in alveolar RMS (aRMS) mediates tolerance to chemotherapy and radiotherapy and that the class I-specific histone deacetylase (HDAC) inhibitor entinostat reduces PAX3:FOXO1 protein abundance. Here, we established the antitumor efficacy of entinostat with chemotherapy in various preclinical cell and mouse models and found that HDAC3 inhibition was the primary mechanism of entinostat-induced suppression of PAX3:FOXO1 abundance...

INTRODUCTION: Many authors suggest that extremity soft tissue sarcomas (ESTS) do not change significantly in size during preoperative radiotherapy (RT). This conebeam CT study investigates the justification to deliver the entire course with one initial RT plan by observing anatomical changes during RT. METHODS: In 2015-2017, 99 ESTS patients were treated with either curative (n=80) or palliative intent (n=19) with a regimen of at least 6 fractions. CTV-to-PTV margin was 1cm...
