Active clinical trials for "Carcinoma"

This is an investigator-initiated, single-arm, exploratory clinical study.The study population consisted of esophageal squamous cell carcinoma patients nonresponding to initial neoadjuvant chemoradiotherapy. The purpose of this study was to evaluate the efficacy and safety of immunotherapy combined with chemotherapy in the adjuvant treatment of esophageal squamous cell carcinoma after surgery.

The purpose of this observational study is to assess the role of plasma concentration monitoring of treatment drugs for patients with metastatic renal cell carcinoma (mRCC) in terms of efficacy and side effects. Furthermore, the investigators intend to evaluate the role of anti-drug antibodies, amount of bound drug to T lymphocytes and receptor polymorphisms in CTLA-4 and PD-1 receptors in treatment failure among patients with mRCC treated with check point immunotherapy. Moreover, polymorphisms in the UGT1A1 gene will be correlated with the pazopanib treatment dose.

This is a national multicenter, randomized, stratified, open label study, aiming to compare mandibular reconstruction (MR) with or without preoperative virtual planning (PVP), in patients with oral/oropharyngeal cancer (OOPC).

To investigate the efficacy and safety of nimotuzumab combined with concurrent chemoradiotherapy versus concurrent chemoradiotherapy in the treatment of local advanced cervical squamous cell carcinoma.

To establish the antitumor activity and safety of the anti-programmed death 1 receptor monoclonal antibody, Treprilimab, in patients with local recurrent/residual nasopharyngeal carcinoma after re-irradiation.Patients with local recurrent/residual NPC after re-irradiation were treated with Treprilimab until disease progression or unacceptable toxicity. The primary end point was objective response rate (ORR) and secondary end points included survival and toxicity.The sample size of this study was estimated on the assumption that response rates (RRs) to Treprilimab should be around 25%,based on a report that was available at the time this study was planned.Furthermore, the RR to noncytotoxic, experimental agents such as pazopanib and cetuximab in similarly pretreated patient cohorts was approximately 5% to 10%. This study's design was based on the modified Simon two-stage optimal design (α=0.05，β=0.2,n1=2/22,n2=7/40). If two responses were observed during the first stage, enrollment was continued until a total of 40 patients was reached.

This phase II trial investigates how well 177Lu-DOTATATE works in treating patients with breast cancer that is stage IV or has come back (recurrent). 177Lu-DOTATATE may shrink or destroy the tumor or circulating breast cancer stem cells if they show evidence of the SSTR2. 177Lu-DOTATATE is a targeted therapy that uses DOTATATE, linked to a radioactive agent called 177Lu. DOTATATE attaches to tumor cells with SSTR2 and delivers 177Lu to kill them. Giving 177Lu-DOTATATE may help decrease the number and size of tumors and the number of circulating cancer stem cells in patient's blood for the treatment of patients with breast cancer positive for SSTR2.

Nasopharyngeal carcinoma (NPC) occurs at a high frequency in southern China, northern Africa, and Alaska, with a reported incidence of 30 cases per 100 000 in Guangdong Province. Endoscopic examination and biopsy are the main methods used for detection and diagnosis of NPC. Early NPC patients achieve favourable prognoses after concurrent radiotherapy and chemotherapy in compassion with advanced NPC patients. Here, the investigators focused on the utility of artificial intelligence to detect early NPC, which based on white light imaging (WLI) and Narrow-band imaging (NBI) nasoendoscopic examination. Having access to this unique population provides an unprecedented opportunity to investigate the effect of intelligent system on diverse nasopharyngeal lesions detection and develop a novel Computer-Aided Diagnosis System.

The prospective observational clinical study will recruit 50 metastatic nasopharyngeal carcinoma (mNPC) patients, detecting patient's chemosensitivity with the circulating tumor cells (CTCs) from peripheral blood and prdicting patient's treatment efficacy with CTCs dynamic change.

This is a prospective, observational, multi-center study examining the long-term outcomes of patients with small, low risk papillary thyroid cancer who offered the choice of active surveillance (close follow-up to monitor for potential disease progression) or immediate surgery.

This is a multi-institutional, prospective, observational registry investigating the safety and efficacy of Accelerated Partial Breast Irradiation (APBI) using a Stereotactic Body Radiation Therapy (SBRT) delivery technique that incorporates real-time image guidance, noncoplanar fields, and respiratory tracking. The study will accrue 200 patients who will be treated to a dose of 30 Gy over the course of 5 fractions. These subjects will then have a follow up time of 5 years
