Active clinical trials for "Carcinoma"

The purpose of this study is to evaluate the clinical efficacy of thymopentin on the prevention of the recurrence and metastasis of small HCC after resection.

This non-interventional study includes patients with advanced and/or metastatic renal cell carcinoma who are treated with SUTENT and who did not receive any other systemic therapy before. The aim of the trial is to increase knowledge about quality of life, safety, efficacy and tolerability under conditions of routine use of Sutent. The individual observation period of each patient will be 1 year.

Thyroidectomy followed by administration of large activities of 131-iodine (131I) is the treatment of choice for differentiated thyroid carcinoma (DTC). The serum thyroglobulin (Tg) measurement during hypothyroidism (offT4-Tg), just before radioiodine thyroid ablation, has proved to be effective for predicting persistent/recurrent disease. However, the Tg measurement cannot be used as a corresponding value for preablative offT4-Tg when rhTSH is used as stimulous before treatment. The present study was undertaken to evaluate if post-thyroidectomy Tg values, measured before rhTSH-stimulation and radioiodine administration, is of prognostic value in patients affected by DTC. We enrolled 28 patients with DTC and submitted to total thyroidectomy. Thyroxine (T4) treatment was started just after surgery to suppress TSH levels. Six to nine weeks later Tg levels were measured both basally (onT4-Tg) and after rhTSH (rhTSH-Tg) stimulation. Subsequently, T4 was stopped and serum Tg measured (offT4-Tg) just before 3700 MBq of 131I-iodide administration. A post-treatment whole body scan (PT-WBS) was performed and neck radioiodine uptake (RAIU) measured. A significant relationship was found between onT4-Tg and both rhTSH-Tg and offT4-Tg. The onT4-Tg levels of 0.2 ng/mL or higher predicted PT-WBS results with a 100% negative and 43% positive predictive values, respectively. Additionally onT4-Tg levels of 0.9 ng/mL or more predicts 12-months recurrences with 100% negative and 60% positive predictive value. In comparison, 1.0 ng/mL or higher offT4-Tg values predicted PT-WBS results and 12-months restaging with 94% and 100% negative and 45% and 27% positive predictive value, respectively. Basing on our data we conclude that preablative onT4-Tg may be of value as prognostic marker when rhTSH-aided radioiodine ablation is done. Additionally, the role of preblative onT4-Tg measurement as a yard-stick for radioiodine ablation should be further evaluate.

This is a retrospective international, multi-center, non-interventional cohort study based on use of data derived from established medical records and secondary analysis of archival tumor samples. The study will collect data on patient and tumor characteristics, PD-L1 status, patterns of treatment, and clinical outcomes, in up to 600 adult patients with recurrent/metastatic SCCHN. SCCHN of interest for this study are defined as the diseases falling into specific ICD-10 or International Classification of Diseases, Ninth Revision (ICD-9) codes (Table 1), depending on anatomical sub-site of the primary tumor. For patient selection, the date of diagnosis of recurrent/metastatic disease will be used as the index date. The patient selection period extends from the 1st March 2011 to the 30th June 2015. This allows for the inclusion of patients with tumor samples of approximately ≤ 5 years age, and ensures approximately 10 months follow-up for living patients recruited at last day of the enrollment window. All patients with a diagnosis of recurrent/metastatic SCC of the oral cavity (tongue, gum, floor of mouth, and other/unspecified part of the mouth), oropharynx, hypopharynx, or larynx during that period will be considered for inclusion in the study (Figure 1). Patients will be identified and followed up through their medical records until death or end of data collection in approximately 20 centers in the US, Asia and Europe. Patients' demographic, clinical characteristics, and medical history will be described. Clinical outcomes including PFS, best response, duration of response, and ORR will be described for the first line and second line of therapy (if any), and OS will be collected A mandatory archived tumor samples will be used to determine PD-L1 status. If a patient has more than one suitable tissue sample, the most recent sample will be used as the mandatory tissue sample. Where available, additional tumor samples obtained at any other time points of the disease will be also collected (optional). The enrolment target is up to 600 patients. Statistical analyses will be performed for the whole cohort, per PD-L1 status and for predefined subgroups.

This is a continuing study which evaluates the long-term safety and efficacy of oral acitretin in an open manner in the treatment of psoriasis, cutaneous disorders of keratinization, multiple basal cell carcinomas and other retinoid responsive diseases.

It is nowadays well established that the immune system can profoundly influence disease outcome in cancer patients. Increasing evidence is indeed showing that patients displaying spontaneous T cell-mediated immune response against their tumor (defined as immune surveillance) have higher chance to respond to therapies and display globally better prognosis. Conversely, patients whose tumor is characterized by immunosuppression, usually involving myeloid cells and chronic inflammation pathways, often undergo rapid progression and rarely benefit from therapy. Hence, capturing the immune features of individual tumors can help to predict disease course and tailor the therapeutic workup in clinical setting.

This trial studies magnetic resonance imaging (MRI) and positron emission tomography (PET) imaging in predictive treatment response in patients with stage IB-IVA cervical cancer. MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. PET is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. Comparing results of diagnostic procedures, such as MRI and PET, done before, during and after radiation and chemotherapy may help doctors predict a patient's response to treatment and help plan the best treatment.

This study will further the understanding of the genetic events leading to the development of RCC.

The purpose of this study is to determine that adjuvant systemic chemotherapy is superior to adjuvant transcatheter arterial chemoembolization(TACE) in prolonging recurrence free survival（RFS） in patients after radical resection of hepatocellular carcinoma.

The purpose of this study is to determine if a new magnetic resonance (MR) protocol is better at diagnosing liver lesions.
