View clinical trials related to Osteogenic Sarcoma.
Filter by:Osteosarcoma is regarded as most common malignant bone tumor in children and adolescents. Approximately 15% to 20% of patients with osteosarcoma present with detectable metastatic disease, and the majority of whom (85%) have pulmonary lesions as the sole site of metastasis. Previous studies have shown that the overall survival rate among patients with localized osteosarcoma without metastatic disease is approximately 60% to 70% whereas survival rate reduces to 10% to 30% in patients with metastatic disease. Though lately, neoadjuvant and adjuvant chemotherapeutic regimens can decline the mortality rate, 30% to 50% of patients still die of pulmonary metastases. Number, distribution and timing of lung metastases are of prognostic value for survival and hence computed tomography (CT) thorax imaging still plays a vital role in disease surveillance. In the last decade, the technology of multidetector CT scanner has enhanced the detection of numerous smaller lung lesions, which on one hand can increase the diagnostic sensitivity for lung metastasis, however, the specificity may be reduced. In recent years, deep-learning artificial intelligence (AI) algorithm in a wide variety of imaging examinations is a hot topic. Currently, an increasing number of Computer-Aided Diagnosis (CAD) systems based on deep learning technologies aiming for faster screening and correct interpretation of pulmonary nodules have been rapidly developed and introduced into the market. So far, the researches concentrating on the improving the accuracy of benign/malignant nodule classification have made substantial progress, inspired by tremendous advancement of deep learning techniques. Consequently, the majority of the existing CAD systems can perform pulmonary nodule classification with accuracy of 90% above. In clinical practice, not only the malignancy determination for pulmonary nodule, but also the distinction between primary carcinoma and intrapulmonary metastasis is crucial for patient management. However, most existing classification of pulmonary nodule applied in CAD system remains to be binary pattern (benign Vs malignant), in the lack of more thorough nodule classification characterized with splitting of primary and metastatic nodule. To the best of our knowledge, only a few studies have focuses on the performance of deep learning-based CAD system for identifying metastatic pulmonary nodule till now. In this proposed study, the investigators sought to determine the accuracy and sensitivity of one computer-aided system based on deep-learning artificial intelligence algorithm for detection and risk stratification of lung nodules in osteogenic sarcoma patients.
After Institutional Review Board approval, adult patients scheduled for total knee arthroplasty (TKA) will be enrolled into the study after obtaining informed consent over a 24 month period. Interim analyses of cases who have completed the 6 month follow up as on 31st October, 2017 will be analyzed as part of the co- principle investigator's thesis. All consenting patients will be assessed for pain preoperatively, the first 3 post-operative days, at 1, 4 and 6 months from the date of surgery. Pain scores will be assessed using the Numerical Rating Scale during the 3 postoperative days. Pain will be managed by the Acute Pain Service team as per standard protocols. The Brief pain inventory (BPI) (short form with translations, obtained with permission from MD Anderson), which assesses pain severity and its impact on daily functions will be administered to the patient in a language familiar to them, preoperatively, at 1, 4 and 6 months postoperatively. The Musculoskeletal Tumour Society Score (MSTS) which evaluates the functional condition (impairment) after completed tumour treatment will be estimated at the end of 6 months from the date of surgery The painDETECT questionnaire (PD-Q) a quick, simple and reliable screening tool to identify the likelihood of a neuropathic pain component in patients and validated in various languages including Hindi and Marathi will be administered preoperatively and at 1, 4 and 6 months after surgery. Details of postoperative chemotherapy and radiation will also be obtained from patient's notes and the electronic medical record. If the patient cannot follow up at the said intervals, the pain scores would be obtained telephonically and the BPI and PD-Q forms in prepaid envelopes would be given to them at discharge which they would have to duly fill in and post them to the given address at the appropriate intervals if they cannot visit the pain clinic. At the 6th month of follow up, they would be requested to visit the pain clinic for an assessment of MSTS score and completing the BPI and PD-Q. INCLUSION CRITERIA:- - Adult patients above 18 years of age, undergoing TKR - Literate: able to read and write in at least one of the following languages English, Hindi and Marathi - Willing to fill forms and post them and/or answer questions on phone EXCLUSION CRITERIA:- - Refusal of consent - Cognitively impaired - Revision TKRs (including cases with wound wash and nail spacer cementing)
Although regorafenib was approved for use in patients who had progressive GIST despite imatinib and/or sunitinib on the basis of phase II and phase III data, it has not been examined in a systematic fashion in patients with other forms of sarcoma. Given the activity of sorafenib, sunitinib and pazopanib in soft tissue sarcomas, and evidence of activity of sorafenib in osteogenic sarcoma and possibly Ewing/Ewing-like sarcoma, there is precedent to examine SMOKIs (small molecule oral kinase inhibitors) such as regorafenib in sarcomas other than GIST. It is also recognized that SMOKIs (small molecule oral kinase inhibitors)such as regorafenib, sorafenib, pazopanib, and sunitinib have overlapping panels of kinases that are inhibited simultaneously. While not equivalent, most of these SMOKIs (small molecule oral kinase inhibitors) block vascular endothelial growth factor and platelet derived growth factors receptors (VEGFRs and PDGFRs), speaking to a common mechanism of action of several of these agents.
The purpose of this study is to find the safe dose of nab-paclitaxel in children with solid tumors, and to see if it works to treat these solid tumors in children and young adults (in Phase 1 ≤ 18 years old and in Phase 2 ≤ 24 years old). After the final dose has been chosen, patients will be enrolled according to the specific solid tumor type, (neuroblastoma, rhabdomyosarcoma, or Ewing's sarcoma), to see how nab-paclitaxel works in treating these tumors.
This treatment study for relapsed high-risk neuroblastoma, Ewings sarcoma, osteogenic sarcoma, rhabdomyosarcoma or synovial sarcoma involves an autologous cancer testis (CT) antigen specific dendritic cell (DC) vaccine preceded by decitabine as a demethylating chemotherapy.
