99m Tc-3PRGD2 SPECT/CT Imaging in the Diagnosis of Lymph Node Metastasis of Esophageal Carcinoma

The esophageal squamous cell carcinoma (ESCC) has high prevalence and mortality in China, which become a severe challenge for public health. The molecular imaging technology has been developed for visualization and precise diagnosis of the tumors. Integrin ?v?3 is a specific marker for tumor. Noninvasive visualization and quantitative analysis of integrin ?v?3 expression provide new opportunities for tumor diagnosis, identification and efficacy monitoring. The peptide containing Arg-Gly-Asp (RGD) can specifically bind to integrin ?v?3 receptor with high selectivity and affinity to achieve the detecting tumor .The SPECT/CT with 99mTc-3PRGD2 has a high specificity in the diagnosis of mediastinal lymphnode metastasis and a greater value in the decision-making of lymphnode dissection. This study is a single-center self-controlled study, It is planned to enroll 30 patients with esophageal cancer , preliminarily confirmed by endoscopic biopsy, . After intravenous injection of 0.3 mCi/kg of 99mTC-3PRGD2, patients underwent single-photon emission computed tomography/computed tomography (SPECT/CT) examination.Subsequently, the patients received chest/abdomen enhanced CT and 18F fluorodeoxyglucose (18F-FDG) positron emission computed tomography /CT (PET/CT) for diagnosis. According to the determination of the researcher, patients who were suitable for surgery received surgery to obtain surgical pathology; For patients who were not suitable for surgery, ultrasound-guided lyphnode biop was performed .In this study, pathological specimens were obtained from gastroscopy, surgical pathology, or ultrasound-guided lymph node biopsy. The diagnostic accuracy, sensitivity , specificity and safety of SPECT/CT with 99mTc-3PRGD2 were evaluated and compared with PET-CT and enhanced CT.

Carboplatin, Nab-Paclitaxel, Durvalumab Before Surgery and Adjuvant Therapy in Head and Neck Squamous Cell Carcinoma

Participants in this study have a type of cancer called squamous cell carcinoma of the head and neck (SCCHN). Their SCCHN has spread around the area where the cancer first started. This is called locally-advanced SCCHN. These participants are eligible for surgery. Previous research with a similar therapy regimen resulted in high rates of cancer shrinkage, high rates of avoiding radiation and its side effects, high cure rate and good quality of life. Radiation can be very toxic. The purpose on this study is to try to avoid radiation. If the participants are not on this study they would be receiving radiation as it is standard treatment of their cancer. In the last study with a similar regimen, about a third of cancers had a pathologic complete response with the first part of the study. This means that the chemotherapy had killed the cancer. The investigators are trying to improve the regimen further with a goal of increasing this rate of complete response to the first part of therapy. The investigators also hope that by improving results in the first part, that more people will be cured and that long term quality of life (especially speech and swallowing) will be improved, both compared to standard therapies and to the last study. Doctors do not know how this therapy will effect the participants. There is no guarantee that this study will benefit the participants. The prior study used a combination of chemotherapy consisting of carboplatin, paclitaxel and a third targeted anti-cancer drug. In this study the investigators are testing the combination of carboplatin, nano-albumin bound paclitaxel and durvalumab. Nano-albumin bound paclitaxel has been shown to be more active against other types of squamous cancers than regular paclitaxel. It is FDA approved for squamous lung cancer, but experimental for head and neck cancer. Durvalumab is an experimental drug that uses the body's own immune system to fight the cancer. Doctors hope that combining Durvalumab with 2 chemotherapy drugs will be effective in treating SCCHN. Durvalumab on its own has been studied in patients with SCCHN and initial results have shown that some subjects' cancer has responded to it. The purpose of this study is to test a combination of chemotherapy to hopefully both increase the number of subjects that respond to therapy while also decreasing the number of side effects that subjects experience.
