Active clinical trials for "Carcinoma"

The purpose of this study is to investigate the feasibility, safety, and long-term prognosis of pancreas-sparing duodenectomy with regional lymphadenectomy in the treatment of early-stage (pTis/pT1/pT2) periampullary carcinoma with or without lymph node metastasis

The aim of the study is to evaluate the efficacy and safety of pemetrexed monotherapy as salvage treatment in patients with relapsed or metastatic squamous cell carcinoma of head and neck.

Skin cancer is the most common cancer in Caucasians, and a basal cell carcinoma (BCC) being the most common skin cancer with around 44,000 new tumours per year, and its incidence is still rising. In the past it has been a disease of the elderly patient but as a consequence of recreational sun exposure and tanning beds, more young patients develop a skin cancer as well. There are different subtypes of BCC and most subtypes are treated by surgical excision. Nowadays, non-invasive techniques as photodynamic therapy (PDT) are common practice to treat superficial BCC (sBCC). Because of these techniques treatment by surgical excision can be avoided with the possibility of complications and scar formation. Both 5-aminolevulino acid (5-ALA) and the more lipophilic methyl aminolevulinate (MAL) can be used as a precursor of the photosensitiser. These agents generate an excess of protoporphyrin IX in metabolic active cells, which are illuminated by a specific light source leading to release of reactive oxygen radicals in tissue. The result is apoptosis and necrosis of tumour cells. At the moment, two treatment protocols are used in the Netherlands: the fractionated 5-ALA 20% (Fagron) protocol according to de Haas and the MAL (Metvix, Galderma) protocol. Because MAL was first marketed and registered as a treatment option for premalignant and superficial malignancies most hospitals in the Netherlands use this topical agent. However, there is no evidence which of the 2 agents is more (cost-)effective and/ or preferred by patients. Objective: to determine which treatment is the most effective treatment in terms of prevention of treatment failure, cost saving and patients preference when comparing fractionated 5-ALA 20% PDT versus MAL PDT in 2 treatment sessions.

This study is a multicenter trial.The primary objective is to estimate short-term efficacy and acute toxicities of nedaplatin to the combination of docetaxel in neoadjuvant chemotherapy followed by nedaplatin in concurrent chemoradiotherapy, compared to cisplatin to the combination of docetaxel in neoadjuvant chemotherapy followed by cisplatin in concurrent chemoradiotherapy for patients with locoregionally advanced nasopharyngeal carcinoma. Secondary objectives are to evaluate the overall survival, the distant metastases free survival, and disease free survival of patients with locoregionally advanced nasopharyngeal carcinoma treated with these regimens.Furthermore,analyze the cost-effectiveness of the regimens.

There are few studies about 2nd line treatment in advanced esophageal carcinoma (AEC), some showed that irinotecan may be effective. The investigators previous study has shown the efficacy and safety of paclitaxel/cisplatin as 1st line treatment, so in this phase II study, the investigators would like to observe the efficacy and safety of Nimotuzumab plus Irinotecan/5FU/leucovorin as 2nd line treatment if AEC after failure to 1st treatment of PTX/DDP.

This is a randomized, double-blinded, placebo-controlled, multi-center Clinical Trial. Patients with no tumor lesions one month after resection of hepatocellular carcinoma will be randomized in a 1:1 ratio to 1 of the 2 treatment groups：6mg/d Tyroserleutide (injection), or placebo. The objective is to evaluate the effect of Injectable Tyroserleutide on the recurrence-free survival,overall survival,quality of life,and the safety and tolerability of subjects after the resection of hepatocellular carcinoma

Skin toxicity is a frequently observed side effect in the era of "molecularly targeted therapies". Skin toxicity following administration of protein kinase inhibitors such as sorafenib, regorafenib, lapatinib, sunitinib, and others can be debilitating to the patient, resulting in dose reduction and discontinuation of treatment. The mechanisms of skin toxicity induced by targeted chemotherapy, such as sorafenib or regorafenib, are poorly understood. Further research is warranted to better understand the pathophysiology of drug-related skin toxicity in this setting and develop correction strategies. This study tests the hypothesis that sorafenib and regorafenib interfere with p63 expression and keratinocyte differentiation and skin remodeling. Eligible study participants will be evaluated clinically for evidence of skin toxicity during their visits to the outpatient Oncology clinics. Study participants will undergo skin biopsies before sorafenib or regorafenib treatment is initiated and once rash develops or 12 weeks into treatment with sorafenib or regorafenib. Skin biopsies will be performed in Oncology clinics by the study investigators and clinic support staff. Study participants will undergo both skin biopsies regardless of whether they develop a rash. In patients who develop a rash the most representative lesion will be biopsied. A normal appearing area of skin will be biopsied in participants who do not develop a rash.

The purpose of this study is to assess the efficacy of Radiofrequency ablation (RFA) and percutaneous acetic acid ablation (PAI) in the management of small hepatocellular carcinoma (HCC) in patients of cirrhosis of liver.

Peri-operative treatment of locally advanced gastric cancer (LAGC) has always been argued by eastern and western scholars. For patients with clinical stage of cT4b/N+M0, or cT4aN+M0, the prognosis is rather poor, and the primary lesions might not be resectable at the time of diagnosis. MAGIC study has showed that pre-and post-operative chemotherapy with 3 cycles of ECF has increased 13% on 5yOS compared with surgery alone; However, eastern studies such as ACTS GC or CLASSIC showed that TS-1 monotherapy or XELOX (oxaliplatin/capecitabine) combination given as adjuvant chemotherapy for stage II or III patients after D2 surgery could achieve the significant survival benefit. So whether perioperative or post operative therapy is more beneficial for LAGC patients lacks of data supported by prospective study. So in this prospective randomized phase III study, the investigators aim to compare the survival benefit as well as the safety for SOX (oxaliplatin/TS-1) as perioperative therapy versus SOX or XELOX as postoperative therapy after D2 dissection.

Objectives: Primary objective - To determine the efficacy of Foscan-PDT compared with Brachytherapy for recurrent or persistent NPC, as determined by macroscopic clinical examination, CT scan and biopsy. The primary endpoint is complete tumour response at 6 months. Secondary objective: To determine the response rates, e.g. presence of tumour on endoscopy, time to progression and overall survival in patients treated with Foscan-PDT compared with brachytherapy To determine the quality of life, as derived from the University of Washington Quality of Life questionnaire in patients treated with Foscan-PDT compared with brachytherapy To evaluate the safety of Foscan-PDT compared with brachytherapy in terms of adverse events and serious adverse events.
