2 Clinical Trials for Histiocytoma
This prospective, multi-center, randomized controlled study aims to assess the efficacy of utilizing 3D printed models in preoperative planning for the excision of tumors involving bony structures within the body. The study is expected to last approximately 12 months and involve up to 150 subjects across 3 sites. Subjects will be randomized in a 1:1 ratio into either the experimental arm, utilizing 3D printed models and imaging, or the active comparator arm, using only imaging. Primary endpoint: Operative time of surgical procedure. Secondary endpoints: Reduction of blood loss, proportion of postoperative adverse events, and negative tumor margins. Exploratory endpoints: Surgical planning ease, changes in surgical plan, and surgeon satisfaction.
The rare histiocytic disorders (RHDs) are characterized by the infiltration of one or more organs by non-LCH histiocytes. They can range from localized disease that resolves spontaneously, to progressive disseminated forms that can be sometimes life-threatening. Since they are extremely rare, there is limited understanding of their causes and best treatment options. Physicians, patients and parents of children with RHDs frequently consult members of the Histiocyte Society regarding the best management of these disorders. Very often, no specific recommendation can be made due to the lack of prospective outcome data, or even large retrospective case series. The creation of an international rare histiocytic disorders registry (IRHDR) could facilitate a uniform diagnosis of the RHDs, as well as the collection and analysis of the clinical, epidemiological, treatment and survival data of patients with RHD. The registry may also lead to future therapeutic recommendations, provide a framework for future clinical trials and create excellent research opportunities.
