Active clinical trials for "Carcinoma"

Background. The main risk factor for the development of hepatocellular carcinoma (HCC) is cirrhosis of any etiology, with an annual risk between 1 and 6%, being currently the leading cause of death in patients with cirrhosis and the third cause of death for cancer in the world. In our country there is little information about the incidence of HCC in this population. It has been shown that there is a change in the gut microbiome (set of genetic material of microorganisms that make up the intestinal bacterial flora) as the severity of the cirrhosis progresses. This change in the microbiome has been associated with clinical decompensation events of cirrhosis. However, there are no previous studies in the world that demonstrate an impact of the change of the microbiome in cirrhosis as a precursor to the development of HCC. Our team has compared the profile of the microbiome in patients with cirrhosis with and without HCC. We observed that patients with HCC present changes in the phylum Firmicutes, genus Fusobacterium and change in the bacteroides / prevotella ratio. This pattern was associated with a pro-inflammatory profile. In murine models, it has been postulated that modulation of the gut microbiome through the use of probiotics could have a clinical role in the prevention of HCC development. This research project aims to answer the following question: in patients with cirrhosis, does the nutritional supplement with probiotics prevent HCC development? Objective: To compare the incidence of HCC through intervention with probiotics in cirrhosis. Methods: A randomized, double-blind, placebo controlled trial of probiotics in patients with Child Pugh A-B cirrhosis at 3-year follow-up. Likewise, the type of microbiome found as a predictor of the risk of HCC development will be evaluated. It will include 280 patients, 140 in each branch. Basal blood and stool samples will be obtained and every 6 months. The typing and quantification of the microbiome in samples of fecal matter will be carried out by amplifying a specific region (V3-V4) of the bacterial 16s rRNA gene. Likewise, the presence of endotoxins (LPS) and cytokines (IL6, TNF alpha) in plasma will be determined to analyze the immune environment and the expression of the TLR4 receptor in mononuclear cells.

The aim of this study is to explore whether endostar combined with IP as treatment could improve progression-free surial time (PFS) and to evaluate the safety of the chemotherapy regimens

The purpose of this study is to observe and evaluate the efficacy and safety of anti-PD-1 antibody SHR-1210 combined with nimotuzumab as second-line therapy in patients with advanced cancerous esophageal squamous cell carcinoma.

SHR-1210 is a humanized anti-PD1 Immunoglobulin G4 (IgG4) monoclonal antibody. This is an open- label，single center ，non-randomized ，Single Arm Exploratory Study . This clinical study is an investigator-initiatedclini-cal trial（IIT ）.The objective of this study is to evaluate the efficacy and safety of adjuvant therapy with anti-PD-1 antibody SHR-1210 and apatinib in patients with Barcelona Clinic Liver Cancer (BCLC) B&C stage hepatocellular carcinoma after surgery.

In order to search for effective and low toxicity anti-tumor angiogenesis drugs, jiangsu hengrui pharmaceutical co., ltd. developed the high-efficiency VEGFR2 tyrosine kinase inhibitor apatinib. This drug is mainly used to treat malignant tumors by inhibiting VEGFR2 to play an anti-angiogenic role. Both in vivo and in vitro experiments have shown that apatinib has good tumor growth inhibition activity for lung cancer. This study aims to further confirm the effectiveness and safety of apatinib third-line treatment for patients with advanced lung squamous cell carcinoma.

Hepatic artery infusion chemotherapy (HAIC) is effective and safe for hepatocellular carcinoma (HCC). Recombinant Human Type-5 Adenovirus (H101) is safe for HCC. The purpose of this study is to evaluate the efficacy and safety of HAIC combined with H101 compared with HAIC alone in patients with unresectable hepatocellular carcinoma (HCC) at barcelona clinic liver cancer A-B stage.

This pilot study will evaluate the effectiveness of using photodynamic therapy for treatment of cutaneous squamous cell in situ (SCCis). Our hypothesis is that PDT will be effective for treating SCCis. This study will also secondarily evaluate the tolerability of using photodynamic therapy for treatment of SCCis. Investigators plan to enroll 40 subjects with biopsy proven SCCis. Exclusion criteria include lesion in high-risk site (head, neck, hands, feet), previous severe adverse reaction to topical 20% aminolevulinic acid (Kerastick), previous severe adverse reaction to blue light (BLU-U), allergy to Tegaderm, primary or secondary immunosuppression, history of > 6 skin cancers in the past year, photosensitizing condition such as lupus, or sensitivity to porphyrins. Age, gender, size, and location of the SCCis will be recorded. All subjects will receive surgical treatment of their SCCis. The control group will undergo a surgical excision of the tumor. After the excision, subjects will be asked to fill out a satisfaction survey. The intervention group will receive PDT plus surgical treatment. Photographs of the lesion will be taken at each study visit. Subjects in the intervention group will then undergo the study procedure of application of topical 20% 5-ALA (Levulan Kerastick; DUSA Pharmaceuticals) to the SCCis. At 3-5 weeks after the initial treatment, the subject will repeat the 3-hour ALA incubation and blue light exposure. At 6 months after the last treatment, subjects in the intervention group will return for clinical follow-up and surgical excision of the lesion. After excision, the specimen will be sent for processing by pathology and subjects will be asked to fill out a satisfaction visual analog scale. All slides will be read by a board-certified dermatopathologist. Side effects will also be monitored using the same graded scale described previously. Mild adverse events that have been associated with PDT, including erythema, skin crusting, superficial blistering, hypopigmentation, and hyperpigmentation. These reactions usually occur during or immediately after the PDT treatment.

This study will evaluate the safety of PD-1 knockout EBV-CTL cells in treating EBV (Epstein-Barr virus) positive advanced stage malignancies. Blood samples will also be collected for research purposes.

Patients enrolled for the study, who are eligible for NACT, will undergo a pre-treatment workup comprising of Evaluation Under Anesthesia (EUA) for tumor Mapping and tissue biopsy along with a PET-CT scan. Subsequently, they would undergo 3 cycles of NACT (weekly thrice) with DCF. They would be reassessed with PET-CT and EUA +/- biopsy after the end of the third cycle. Those who are achieving CR would undergo adjuvant CTRT. Subjects who have a PR in the PET-CT scan will be re-classified based on the biopsy report. If they remain in the PR group they will undergo surgery but if the biopsy in is negative for malignancy, they will undergo adjuvant CTRT. Those subjects with SD or PD would undergo surgery. Subsequently, further radiation and/ or chemotherapy will be decided based on the final histopathology (of the surgical specimen) reports. PET-CT and EUA +/- HPE analyses would be repeated on follow-up after 3 months of treatment completion.

The current random, double-blind, controlled, clinical trial was designed to evaluate the impact on therapeutic effect and tolerance of treatment for patients with hepatocelluclar carcinoma in transcatheter arterial chemoembolization (TACE) of dexamethasone application.
