Active clinical trials for "Carcinoma"

The primary purpose of this study is to compare balloon Eustachian tuboplasty (BET) combined with tympanostomy tube insertion and simply tympanostomy tube insertion in the treatment of otitis media with effusion (OME) in post-radiotherapy patients on the improvement of subjective symptoms (ear fullness, etc.) and the tympanogram. The secondary purpose is to clarify the effects of BET on the incidence of middle ear infection and slippage of ventilation tube during tube retention, as well as to determine the difference of hearing improvement between the two management methods.

Whether the introduction of immunotherapy can transform unresectable esophageal cancer into resectable, or even achieve R0 surgical resection, has not been reported yet. We plan to conduct a prospective, single-center, single-arm phase II clinical study of the safety and efficacy of tislelizumab combined with chemotherapy in the treatment of unresectable esophageal squamous cell carcinoma.

Subjects with cT2-T3N0M0 urothelial cancer of the bladder will be enrolled. After completing two cycles of pembrolizumab, subjects will undergo a restaging MRI of the abdomen and pelvis with a standard acquisition protocol (as outlined in the protocol) as well as CT chest. A CT of the abdomen and pelvis may be performed if there are contraindications to MRI. Patients will also undergo a restaging cystoscopy and biopsies/TURBT as outlined in the protocol. Patients achieving a clinical complete response to treatment (defined in the protocol) will proceed with "maintenance" single agent pembrolizumab followed by surveillance. All other patients will proceed with standard of care local therapy as per their treating physicians followed by "adjuvant" pembrolizumab.

This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and waste as urine. Most papillary tumors look like long, thin finger-like growths under a microscope. It is also called papillary kidney cancer or PRCC. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of cancer cells. Combination therapy with atezolizumab and cabozantinib may shrink the cancer and allow a longer survival time in patients with metastatic renal cell carcinoma.

The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).

Neoadjuvant chemotherapy treatment can be used for specific UTUC patients, especially for highly staged and/or grade tumors, such as kidneys with potentially decreased renal function after RNU. Neoadjuvant therapy is a series of treatments administered preoperatively for UTUC, mainly chemotherapy, and in recent years, novel therapies of immunotherapy have emerged. Since conventional cisplatin neoadjuvant regimens also require high preoperative renal function, neoadjuvant therapy regimens such as immunotherapy provide more effective and feasible treatments for patients who are intolerant to current cisplatin chemotherapy regimens. The aim of this study was to explore a novel preoperative neoadjuvant immunotherapy for UTUC. To further observe the feasibility and safety of this regimen in the field of UTUC.

This phase II trial tests the safety of positron emission tomography (PET) guided stereotactic body radiation therapy (SBRT) and how well it works to treat non-small cell lung cancer (NSCLC), melanoma, and renal cell carcinoma (RCC) that has up to 5 sites of progression (oligoprogression) compared to standard SBRT. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. A PET scan is an imaging test that looks at your tissues and organs using a small amount of a radioactive substance. It also checks for cancer and may help find cancer remaining in areas already treated. Using a PET scan for SBRT planning may help increase the dose of radiation given to the most resistant part of the cancer in patients with oligoprogressive NSCLC, melanoma, and RCC.

Hepatocellular carcinoma is one of the most intractable primary malignancies in the hepatobiliary and pancreatic tract with a poor overall survival worldwide. Unfortunately, the vast majority of hepatocellular carcinoma patients suffer from advanced unresectable or metastatic disease at diagnosis. Currently targeted therapy alone, or in combination with anti-vascular endothelial growth factor antagonist, is the standard first-line treatment for metastatic hepatocellular carcinoma. On the other hand, there is growing evidence suggesting that radiation therapy (external or internal) with or without immune checkpoint inhibitors can produce or even augment abscopal effect in which the tumours away from the radiation field also show significant tumour shrinkage. The underlying mechanism of eliciting abscopal effect includes the increased antigen presentation by the myeloid cells within the tumour stroma leading to enhanced tumour cell killing. Previous case reports showed that radiation therapy alone can induce abscopal effect in mice and human models. However, a robust and concrete evidence of abscopal effect with combinational immune checkpoint inhibitors and radioembolisation or external radiation therapy in hepatocellular carcinoma is still lacking. This study investigates the efficacy and safety of immune checkpoint inhibitors and radioembolisation as first-line treatment for previously untreated metastatic hepatocellular carcinoma.

TPF is still recommended as the preferred induction chemotherapy regimen for nonsurgical treatment of patients with LA HNSCC. Based on the KEYNOTE-048 study, all major guidelines recommend PD-1 monotherapy or PD-1 combined with chemotherapy as the new first-line standard treatment for patients with advanced HNSCC. The immunotherapy in operable LA HNSCC was also explored as neoadjuvant therapy due to the excellent data in advanced HNSCC. These explorations have also achieved good results. Therefore, this study aims to explore the pathological remission rate, the long-term benefit and safety of Tislelizumab combined with albumin paclitaxel, cisplatin and fluorouracil for locally advanced oral squamous cell carcinoma.
