Active clinical trials for "Sarcoma"

The goal of this clinical research study is to measure the amount of inflammatory proteins inside the body before and after lymphatico-venular bypass surgery. This will help doctors learn if anti-fibrotic or anti-inflammatory drugs/treatments given with the surgery can improve how well the surgery works.

RATIONALE: Gathering information from patients who have undergone treatment for upper gastrointestinal cancer or gynecological cancer may help doctors learn more about patients' physical and psychosocial rehabilitation needs and plan the best treatment. PURPOSE: This clinical trial is studying the physical and psychosocial rehabilitation needs of patients after diagnosis and treatment of upper gastrointestinal cancer or gynecological cancer.

This study will use diffusion weighted MRI (DWI MRI) and dynamic-contrast enhanced MRI (DCE MRI) techniques to detect changes in sarcoma tumour vasculature. The main aims of this study are to correlate histological response of soft tissue sarcoma after pre-operative radiotherapy with several pre-treatment DCE and DWI MRI parameters and to assess the impact of these on early response prediction. Detected changes may reflect the sensitivity of the tumour to radiotherapy and may be associated with long term outcomes after treatment. 15 patients normally having pre-operative radiotherapy as part of their sarcoma treatment will be recruited to this study. Patients will have an additional three specialised MRI scans: one prior to the start of radiotherapy, one during the second week of radiotherapy while on treatment and one scan a week before surgery but after the completion of radiotherapy. Post-operatively, results of the histological examination of the sarcoma will be correlated to both the MRI scan data and outcomes after treatment

RATIONALE: Diagnostic procedures, such as anal swab collection, digital rectal examination, and anal endoscopy and biopsy, may help find and diagnose anal and genital human papillomavirus infection and squamous intraepithelial lesions and help doctors plan better treatment. PURPOSE: This clinical trial is studying ways to detect anal and genital human papillomavirus infection and squamous intraepithelial lesions in HIV-positive patients enrolled in an AIDS cancer clinical trial.

RATIONALE: Giving pain medication into the space between the wall of the spinal canal and the covering of the spinal cord or giving it into a vein may help lessen pain caused by cancer surgery. It is not yet known whether epidural analgesia is more effective than patient-controlled analgesia in controlling pain in patients who have undergone surgery for gynecologic cancer. PURPOSE: This randomized clinical trial is studying epidural analgesia to see how well it works compared to patient-controlled analgesia in treating patients who have undergone surgery for gynecologic cancer.

Epidemiological data show that the incidence of carcinoma, the most common cancer, is strongly linked to the age. Non Melanoma Skin Carcinomas (NMSCs) (the most frequent cancers in the elderly population) derive from keratinocytes of the basal layer of the epidermis, from differentiated keratinocytes of the more superficial layers or from stem cells of hair follicles. Unlike NMSCs, soft-tissue sarcomas, including those deriving from dermal fibroblasts, are very rare (less than 1% of all cancers). Our overall purpose is to decipher the molecular pathways activated during the aging of these tissues that may explain why they have a so different propensity to undergo a malignant transformation. Given that senescent cells accumulate in the dermis and epidermis with age, we will constitute two groups : "young skin" that we arbitrarily limit to the range ≥ 18 and ≤ 40 and "aged skin" ≥ 55. Thus the main objective of our study is to search within 2 age groups (≥ 18 and ≤ 40 years and ≥ 55 years) the expression of senescence markers on healthy skin tissue.

This non-interventional study aims primarily at assessing the clinical effectiveness and the impact of the therapy on cancer-related symptoms and patients' HRQoL. In addition, it represents an attempt towards gaining experience on the routine use of trabectedin in daily clinical practice in a representative sample of Greek subjects with aSTS.

The investigators have recently developed an innovative optical molecular imaging platform (called PRODIGI) based on high-resolution fluorescence and white-light technologies in a hand-held, real-time, high-resolution, non-invasive format. PRODIGI offers a non-contact means of obtaining instantaneous image-based measurements of diagnostically-relevant biological and molecular information of a wound and surrounding skin tissues for the first time and could have significant impact on improving conventional wound care, management, and guidance of intervention. In preliminary preclinical testing, the investigators have discovered that when wounds are illuminated by violet/blue light, endogenous collagen in the connective tissue matrix emit a characteristic green fluorescent signal, while most pathogenic bacterial species emit a unique red fluorescence signal due to the production of endogenous porphyrins. Therefore, with autofluorescence imaging, no exogenous contrast agents are needed during imaging, making this approach particularly appealing as a diagnostic imaging method for clinical use. In the context of this study, PRODIGI is used to assess wound complications in patients diagnosed with soft tissue sarcoma and treated with pre-operative radiotherapy. Both pre- and postoperative external beam radiotherapy combined with limb salvage surgery have similarly high rates of local control in the management of extremity soft tissue sarcoma. The main acute side effect associated with preoperative radiotherapy is wound healing complications. Wound care overall is a major clinical challenge and presents an enormous burden to health care worldwide. The objective of this clinical study is to determine if PRODIGI coupled with an optical tracking platform has clinical utility in identifying, quantitatively measuring and longitudinally tracking bacterial imbalance on the patient's intact skin surface at the location of the surgical resection site for adult patients with lower limb soft tissue sarcoma treated with preoperative intensity-modulated radiation therapy and limb salvage surgery and, further, to investigate whether this bacterial imbalance is related to radiotherapy dose and wound complications.

The aim of the proposed project is to study the long-term impact of adjuvant systemic multi- agent chemotherapy (cisplatin, anthracyclines, vincristine, methotrexate, alkylating agents) in survivors (treated between 1992 and 2014 in UZ Leuven) of paediatric bone or soft tissue sarcomas on neurocognitive functioning.
