Active clinical trials for "Carcinoma"

This project will include at least 40 patients with hepatocellular carcinoma (HCC) who will receive transcatheter arterial chemoembolization (TACE) as a sole method for the management. The serum is collected before and at the 3rd and 7th day after TACE. The serum levels of vascular endothelial growth factor, angiopoietin 2, endostatin and cathepsin L are determined. All patients will be evaluated according to the TNM system for the cancer staging before and 3 months after each session of treatment. The vascularity of tumor, the drug and the dose used for embolization, and the area of infarction will be recorded. These data will be compared with the clinical courses of the patients to obtain the most suitable way in the management of these patients.

Basal cell carcinoma (BCC) is the most common skin cancer in the US and can cause significant adverse effects. Mohs micrographic surgery, the treatment of choice for higher risk BCC, allows for removal of lesions with preservation of healthy tissue. Although the BCC recurrence rate post Mohs surgery is estimated at 1-2%, recent data is lacking to validate this historical measurement. Our purpose is to determine the current recurrence rate of BCC after Mohs surgery.

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.

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.

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 study will collect data of patients who are treated with TACE followed by sorafenib for hepatocellular carcinoma (HCC) or patients without Sorafenib after TACE. In contrast to a prior observational study on sorafenib (GIDEON study), where pre-treatment with TACE was documented retrospectively, this study will collect more detailed information about the TACE treatment and the status of a patient when treatment with sorafenib is started.

The main purpose of this observational study with Irinotecan onkovis is to determine the number of treatment cycles and the quantity of Irinotecan onkovis needed for this purpose under the special circumstances of ambulant chemotherapy. Onkovis aims to contribute to an economical utilization of the chemotherapeutics. This includes provision of appropriate packaging sizes to decrease the excess quantity to be discarded, and thus also follows this objective. Secondary objective is the assessment of the side effects of Irinotecan onkovis. To this end, data regarding co-medication and adverse events are also collected.

This prospective, single arm, multi-center pilot study includes 120 mRCC patients over 65 years, no prior systemic treatment, determined to be candidates for systemic therapy by the investigator. The treatment with Sorafenib should comply with the recommendations written in the local product information. The primary endpoint is overall survival. The secondary endpoints including other effectiveness points, safety and patients characteristics. With 120 completed patients, if the observed survival rate at 12 months is 60%, the width of a 95% confidence interval will be approximately 18%.

The main purpose of this observational study with Oxaliplatin onkovis is to determine the number of treatment cycles and the quantity of Oxaliplatin onkovis needed for this purpose under the special circumstances of ambulant chemotherapy. Onkovis aims to contribute to an economical utilization of the chemotherapeutics. This includes provision of appropriate packaging sizes to decrease the excess quantity to be discarded, and thus also follows this objective. Secondary objective is the assessment of the side effects of Oxaliplatin onkovis. To this end, data regarding co-medication and adverse events are also collected.
