66 active trials for Osteosarcoma

A Post-treatment Program to Identify and Manage Complications Related to Oncology or Hematology Treatments in Cancer Survivors.

INTRODUCTION: Approximately 44% of cancer survivors experience a deteriorated quality of life 5 years after diagnosis due to late onset of complications related to cancer treatments. The objective of the study is to evaluate the incidence rates of treatment-related complications, identify sub-clinical abnormalities and risk factors in patients participating in the PASCA post-treatment program. METHOD: PASCA is a single-center, interventional cohort study of adult patients who received at least chemotherapy and with a complete remission to a testicular germ cell tumor, primary non-metastatic invasive breast carcinoma, high-grade soft tissue sarcoma, osteosarcoma, Ewing's sarcoma, acute myeloid leukemia, Hodgkin's or aggressive non-Hodgkin's lymphoma. Four assessment visits will be scheduled at 1 month (T1), 6 months (T2), 24 months (T3) and 60 months (T4) after completion of treatment. During these visits, 22 complications will be screened and follow-up care will be systematically offered to the health professional concerned by the complication in case of a positive result. The screening will contain the following elements: screening self-questionnaires, quality of life questionnaire, 12 biological parameters, a urinalysis evaluating hematuria, proteinuria, and leukocyturia, a spirometry, an electrocardiogram, 5 tests evaluating physical condition, vital signs and the perimetric measurement between both arms. DISCUSSION: This systematic screening could highlight a number of complications occurring after cancer treatments. Sub-clinical abnormalities and new risk factors could also be identified. This new organization of care could improve the quality of life of adult cancer survivors.

Diffusion Weighted Magnetic Resonance in Imaging Younger Patients With Newly Diagnosed Bone or Soft Tissue Sarcomas

Children with sarcomas are routinely assessed with a variety of imaging techniques that involve the use of ionizing radiation. These include computed tomography (CT), nuclear bone scan, and positron emission tomography-CT (PET-CT). Pediatric sarcoma patients undergo many imaging studies at the time of diagnosis, during therapy and for years following completion of therapy. Because children are in a stage of rapid growth, their tissues and organs are more susceptible to the harmful effects of ionizing radiation than are adults. Furthermore, compared to adults, children have a longer life expectancy and, therefore, a longer period of time in which to develop the adverse sequelae of radiation exposure, such as the development of second malignancies. Alternative experimental methods of measuring tumor response will be compared to current standard of care measures to determine if the experimental method is equivalent to methods currently being used. Investigators wish to determine if they can reduce patient's exposure to the harmful effects of ionizing radiation by replacing imaging studies that use radiation with whole body diffusion weighted magnetic resonance imaging (DW-MRI) which does not use any radiation. They also want to know if DW-MRI measurements of the tumor can tell how well the tumor is responding to therapy. There have been studies in adults with cancer that have shown that DW-MRI provides useful information about how tumors are responding to therapy. There have only been very small studies of DW-MRI in children with tumors in the body. Therefore, the role of DW-MRI in pediatric sarcoma patients is not yet known and it is still experimental. This study might give us important information that could help us treat other children with bone or soft tissue sarcomas in the future.

ABCB1/P-glycoprotein Expression Influence on Non-metastatic Osteosarcoma of the Extremities

Post-authorization, observational, multicenter and prospective study in patients between 2 and 30 years old diagnosed with non-metastatic high-grade osteosarcoma of the extremities. All patients included in the study will receive the initial neoadjuvant treatment prescribed by the doctor of each center, according to standard practice (involving methotrexate, cisplatin, and adriamycin). This initial treatment precedes surgical treatment. After surgical treatment, the histological response to neoadjuvant chemotherapy will be evaluated. The histological response to primary chemotherapy will be expressed as a percentage of tumor necrosis. In the case of tumor necrosis above 90% the patient is defined as a "good responder" in case of a lower percentage as a "poor responder". As an adjuvant treatment, the following options may be given according to standard practice in each center: - If there is overexpression of ABCB1 / P-glycoprotein and poor response to induction treatment, in many sites ifosfamide at high doses and MTP-PE, is incorporated in addition to adriamycin. - If there is overexpression of ABCB1 / P-glycoprotein and a good response to induction treatment, in many centers the option of additional administration of methotrexate, CDDP and adriamycin will be chosen. - If there is no overexpression of ABCB1 / P-glycoprotein, the administration of methotrexate, adriamycin and cisplatin will be chosen in many sites. In some sites they will consider the non-administration of MTP-PE or the non-administration of high doses of ifosfamide. And, in some hospitals, they will consider administering MTP-PE to all patients.
