Radiation to the chest wall is common before resection of tumors. Osteoradionecrosis can occur after radiation treatment. Radical resection and reconstruction can be lifesaving. Soft tissue coverage using myocutaneous or omental flaps is determined by the quality of soft tissue available and the status of the vascular pedicle supplying available myocutaneous flaps. Radiation-induced sarcomas of the chest wall occur most commonly after radiation therapy for breast cancer. Although angiosarcomas are the most common radiation-induced sarcomas, osteosarcoma, myosarcomas, rhabdomyosarcoma, and undifferentiated sarcomas also occur...

BACKGROUND: Li-Fraumeni Syndrome (LFS) is a rare disease with autosomal dominant inheritance linked to germline mutations of tumor suppressor gene TP53. These patients are predisposed to malignancies such as sarcoma, breast cancer, leukemia, and other malignancies. Breast cancer, the most common malignancy in adult patients with LFS, has an early-onset presentation and is usually treated as per the guidelines for the general population due to the limited literature about breast cancer in LFS...

The RASopathy neurofibromatosis 1 is an autosomal dominant hereditary cancer syndrome that represents a major risk for the development of malignancies, particularly malignant peripheral nerve sheath tumors (MPNSTs). MPNSTs are unique sarcomas that originate from the peripheral nerve and represent the only primary cancer of the peripheral nervous system. To date, surgery is the only treatment modality proven to have survival benefit for MPNSTs and even when maximal surgery is feasible, these tumors are rarely curable, despite the use of chemotherapy and radiation...

Primary prostatic sarcomas are rare, reportedly comprising less than 1% of all prostate malignancies. Most patients present with lower urinary tract symptoms due to bladder outlet obstruction. Prostate-specific antigen (PSA) is typically normal. Histological confirmation and staging by a computed tomography (CT) or magnetic resonance imaging (MRI) scan of the pelvis and abdomen are essential for diagnosis and treatment planning. The differential diagnosis includes sarcomatoid prostate cancer or benign spindle cell tumors...

Uterine sarcomas are rare malignant uterine neoplasms that are responsible for a large majority of uterine cancer-associated deaths. The subtypes include leiomyosarcomas, endometrial stromal tumors, and adenosarcomas. Standard treatment includes complete surgical resection. Adjuvant treatment with chemotherapy, hormonal therapy, or radiation may be considered in patients with high-risk disease. However, because the ability of adjuvant treatment to improve overall survival in patients with uterine sarcomas is unclear, there is no standard recommendation regarding adjuvant therapy...

Granulocytic Sarcoma (GS) is a rare condition with a wide list of differential diagnosis and debatable guidelines of treatment in different cancer centers. Most of literature recommended systemic chemotherapy with or without radiation therapy and small role of surgery. One of the rarest sites for myeloid sarcoma is hard palate, which usually worsen the quality of life of the patient due to difficulty in feeding, drinking and speaking. We are reporting a case of hard palatine fistula caused by granulocytic sarcoma, in which we tried to get local control of disease with 3 dimension conformal radiation therapy 3DCRT and surgery with systemic control with chemotherapy using recommendation of multidisciplinary team and targeting mainly patient quality of life...

Sarcoma is a type of cancer affecting connective, supportive, or soft tissue of mesenchymal origin. Despite rare incidence in adults (<1%), over 15% of pediatric cancers are sarcoma. Sadly, both adults and children with relapsed or metastatic disease have devastatingly high rates of mortality. Current treatment options for sarcoma include surgery, radiation, and/or chemotherapy; however, significant limitations exist with respect to the efficacy of these strategies. Strong impetus has been placed on the development of novel therapies and preclinical models for uncovering mechanisms involved in the development, progression, and therapy resistance of sarcoma...

Patients treated with radiation have an increased risk of developing second cancers, of which carcinomas, sarcomas, and hematological malignancies have most commonly been reported. Neuroendocrine carcinomas (NEC) are rarely reported in patients previously treated with radiation. Two patients, who had successfully undergone chemoradiotherapy for head and neck cancers at our institution, developed secondary NEC within the radiation field more than five years after the treatment. Both patients underwent curative-intent treatment of secondary malignancies, one with chemotherapy, radiation and surgery (Case 1) and the other with chemotherapy and surgery (Case 2)...

BACKGROUND: Childhood cancer survivors can have a high burden of chronic conditions related to cancer treatment, some of which are debilitating or potentially life-threatening. Much remains to be learned about late effects in bone and soft tissue sarcoma survivors. PROCEDURES: The Utah Cancer Registry was used to identify survivors of bone (N = 71) and soft tissue sarcomas (N = 98) who were diagnosed at ages 0-20 years between 1973 and 2007 and were alive at least 5 years after diagnosis...

The long-term overall survival of Ewing sarcoma (EWS) patients remains poor; less than 30% of patients with metastatic or recurrent disease survive despite aggressive combinations of chemotherapy, radiation and surgery. To identify new therapeutic options, we employed a multi-pronged approach using in silico predictions of drug activity via an integrated bioinformatics approach in parallel with an in vitro screen of FDA-approved drugs. Twenty-seven drugs and forty-six drugs were identified, respectively, to have anti-proliferative effects for EWS, including several classes of drugs in both screening approaches...

STUDY QUESTION: Is there an association between the need for medical puberty induction and the diagnosis or treatment received in girls who have undergone cryopreservation of ovarian tissue for fertility preservation? SUMMARY ANSWER: There was a clear association between the intensity of treatment received and requirement for medical puberty induction but no association with the diagnosis. WHAT IS KNOWN ALREADY: Although it cannot be predicted which girls will become infertile or develop premature ovarian insufficiency (POI) following intensive chemotherapy or irradiation, patients who are at high risk of POI should be offered ovarian tissue cryopreservation (OTC)...

Ewing's sarcoma (ES) is a highly aggressive and metastatic tumor in children and young adults caused by a chromosomal fusion between the Ewing sarcoma breakpoint region 1 (EWSR1) gene and the transcription factor FLI1 gene. ES is managed with standard treatments, including chemotherapy, surgery and radiation. Although the 5-year survival rate for primary ES has improved, the survival rate for ES patients with metastases or recurrence remains low. Several novel molecular targets in ES have recently been identified and investigated in preclinical and clinical settings, and targeting the function of receptor tyrosine kinases (RTKs), the fusion protein EWS-FLI1 and mTOR has shown promise...

Primary malignant tumors of the aorta are extremely rare, and the diagnosis is difficult from the clinical onset. Accordingly to the principles of cancer surgery, "en bloc" resection of the tumor-involved aorta and graft interposition is the gold standard, but it is still technically challenging and comorbidities may rule out some patients from an operative treatment. Thoracic endovascular aortic repair has been reported anecdotally, but it is an ease and rapid alternative in urgent circumstances and proved to be effective to relieve symptoms caused by these lesions...

Ewing's sarcoma (ES) is the second most common paediatric cancer of the bone. Standard therapy includes surgery or radiation for local control of primary and relapsed lesions and chemotherapy for systemic control. Irreversible electroporation (IRE), which uses short electrical pulses to induce pores and ablate neoplastic cells, has emerged as an alternative method of local control for inoperable metastatic liver and lung lesions. We present the first case in which IRE was used for local control of bony ES. This method has achieved successful local tumour control in our patient for 3 years...

Primary musculoskeletal cancer and metastatic disease to bone in pregnant patients presents major treatment challenges. Although uncommon, musculoskeletal malignancies in pregnant women have been reported. When diagnosing and treating these patients, the mother's health must be managed appropriately while ensuring that fetal development is not deleteriously affected. Extensive radiographic imaging and more advanced techniques are often necessary to fully characterize the extent of disease. When possible, magnetic resonance imaging should be used instead of computed tomography to limit exposure of the conceptus to radiation...

Sarcomas are malignant tumors accounting for a high percentage of cancer morbidity and mortality in children and young adults. Surgery and radiation therapy are the accepted treatments for most sarcomas; however, patients with metastatic disease are treated with systemic chemotherapy. Many tumors display marginal levels of chemoresponsiveness, and new treatment approaches are needed. MAP17 is a small non-glycosylated membrane protein overexpressed in carcinomas. The levels of MAP17 could be used as a prognostic marker to predict the response to bortezomib in hematological malignancies and in breast tumors...

BACKGROUND: The incidence of endometrial cancer increases with age and is associated with medical comorbidities such as obesity and diabetes. Although a few cohort studies of <500 patients showed an association between comorbidity and survival in patients with endometrial cancer, the degree of association must be better described. The Adult Comorbidity Evaluation 27 is a validated comorbidity instrument that provides a score of 0-3 based on the number of and severity of medical comorbidities...

Synovial sarcoma is a soft-tissue sarcoma and a rare type of cancer. Unfortunately, effective chemotherapies for synovial sarcomas have not been established. In this report, we show that synovial sarcoma cell lines have reduced repair activity for DNA damage induced by ionizing radiation (IR) and a topoisomerase II inhibitor (etoposide). We also observed reduced recruitment of RAD51 homologue (S. cerevisiae; RAD51) at sites of double-strand breaks (DSBs) in synovial sarcoma cell lines that had been exposed to IR...

Sarcomas are a rare group of malignant tumors of mesenchymal origin that comprise 1% of all adult cancers. Despite initial surgery, distant metastatic disease will develop in approximately 25% of patients, and standard chemotherapy has limited durable efficacy. There is a dire need for more effective and less toxic therapies for the treatment of metastatic sarcoma. The immune system plays a major role in cancer control and progression. There have been tremendous breakthroughs in other malignancies by manipulating the immune system with checkpoint inhibitors...
