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...

INTRODUCTION: Orbital Granulocytic Sarcoma (OGS) is an uncommon manifestation associated with haematological malignancies. Chemotherapy remains the cornerstone of the treatment. The role of radiation is not well-defined. AIM: To evaluate the effect of radiation in OGS and to define an optimal dose for achieving adequate local control. MATERIALS AND METHODS: This was a retrospective analysis of 11 patients who received radiation therapy to orbit for Granulocytic Sarcoma (GS) between 2007 and 2014 at a tertiary cancer center in India...

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 co-morbidities 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...

INTRODUCTION: Angiosarcomas of the breast are a rare subtype of sarcomas that frequently are diagnosed after radiation therapy for primary breast cancer. Primary angiosarcomas are rare entities accounting 0.05% of all malignant breast neoplasm. PRESENTATION OF CASE: We report a case of primary angiosarcoma of the breast in a 25 years woman, with no previous radiotherapy, treated with a total mastectomy followed by radio-chemotherapy. DISCUSSION: Total mastectomy appears to be the only treatment known that has proven to benefit these patients...

PURPOSE: Sarcomas are a rare and heterogeneous variant of cancer. The standard of care treatment involves surgical resection with radiation in high-risk patients. Despite appropriate treatment approximately 50 % of patients will suffer and die from recurrent disease. The purpose of this article is to review the current evidence concerning the use of neoadjuvant chemotherapy with or without radiation in soft tissue sarcomas. METHODS: An in-depth literature search was conducted using Ovid Medline and PubMed...

REVIEW
Jens Jakob, Peter Hohenberger
The management of locally advanced extremity soft tissue sarcoma of the limbs is challenging, particularly for recurrent tumors and those adjacent to neurovascular bundles and joints. Typically, the tumors are large, below the fascia, and high-grade (T2b or stage III according to the American Joint Committee on Cancer) and thus require multimodal therapy. Treatment options must be tailored to patient and tumor characteristics. Isolated limb perfusion with recombinant human tumor necrosis factor α and melphalan (TNF-ILP) adds a therapeutic option to radiation therapy (RT) and systemic chemotherapy...

BACKGROUND: Radiation therapy is the mainstay strategy for the treatment of nasopharyngeal cancer (NPC). Intensity-modulated X-ray therapy (IMXT) alone is the current standard for stage I and II NPC. For stage III and IV A/B diseases, concurrent chemotherapy should be provided in addition to IMXT. However, optimal treatment for locally recurrent NPC after previous definitive dose of radiotherapy is lacking. Various techniques including brachytherapy, IMXT, stereotactic radiosurgery or radiotherapy (SRS or SBRT) have been used in the management of locally recurrent NPC...

Vulvar neoplasms represent four percent of all gynecological cancers. While most cases of vulvar neoplasms are benign, two percent of patients present with malignant disease. We present the case of a 37-year-old premenopausal female who presented to an outside institution with a lump in her left vulva, which had progressively enlarged to the size of an egg. A wide local excision of the left vulva was performed, and the pathology revealed a high-grade sarcoma, not otherwise specified (NOS), with negative margins...

Here we evaluate the current status of clinical research on regional hyperthermia (RHT) in combination with chemotherapy or radiation therapy in paediatric oncology.Data were identified in searches of MEDLINE, Current Contents, PubMed, and references from relevant articles using medical subject headings including hyperthermia, cancer, paediatric oncology, children, radiation therapy and chemotherapy. Currently, only two RHT centres exist in Europe which treat children. Clinical RHT research in paediatric oncology has as yet been limited to children with sarcomas and germ cell tumours that respond poorly to or recur after chemotherapy...

The Children's Cancer Survivorship Study reports more chronic illnesses in sarcoma survivors than other pediatric cancers. Chemotherapy and radiation put survivors at risk for developing chronic illnesses, including heart disease, diabetes, hypertension, and kidney failure. Sarcoma survivors may have a reduced life expectancy and signs of heart disease in their 30s and 40s. Since these medical problems occur much later in the general population, they often go undetected or misdiagnosed in sarcoma survivors, creating delays in intervention and treatment...
