This study is a prospective, randomized, multicenter clinical trial aiming to enroll 428 patients with non-muscle-invasive bladder cancer (NMIBC) from the Department of Urology at Jiangsu Provincial People's Hospital and its affiliated centers, who have undergone their initial transurethral resection and are scheduled for a second resection. Within 1-6 weeks after the first resection and prior to the second resection, 100ml of routine urine will be collected and sent within 24 hours to Beijing Genetron Health Clinical Laboratory Co., Ltd. for the extraction of urinary sediment DNA, which will then undergo genome-wide low-depth sequencing. Patients with positive test results will proceed with the second resection, while those with negative results will be randomly assigned in a 1:2 ratio to either the intervention group, which will not undergo a second resection, or the control group, which will undergo the second resection. All enrolled patients will be followed up for two years. The study will statistically analyze and compare the two-year recurrence-free survival rates between the two groups and evaluate the predictive capability of the test results for follow-up recurrence.
Eligibility: 18 Years to 80 Years · All · * Patients with NMIBC who have completed the initial transurethral resection and are scheduled for a second resection, as recommended by guidelines or physician's choice:
1. Incomplete initial TURBT due to various reasons (including large tumor size, high risk of intraoperative bleeding, extensive tumor range, etc.), posing a risk of residual tumor;
2. Absence of muscle layer tissue in the initial resection specimen;
3. Post-initial resection pathology indicating T1 stage;
4. Post-initial resection pathology indicating G3/high-grade tumor, excluding pure carcinoma in situ;

Epstein Barr virus infects over 90% of human population and persists during lifetime. After infecting B lymphocytes, EBV remains latent in memory B cells. In immunocompromised patients, primary infection could lead to an uncontrolled EBV infected B cells proliferation because of impaired T cell specific cytotoxicity. The latent EBV infection is characterized by expression of restricted latent gene products, which drive cell proliferation and progression to PTLD. As a consequence, EBV seronegativity and EBV mismatch are major risk factors for developing PTLD. The investigators reported in a previous work from the French Registry that the incidence of PTLD was multiplied by ten in adult EBV negative kidney transplant recipients. Moreover, even if the event is relatively rare after transplantation, the prognosis is severe with high morbidity and an overall mortality rate around 50%.
Nowadays, few and inconsistent data exist regarding beneficial preventing strategies like antiviral therapy, reduction of immunosuppression or immunoglobulin infusion in this high-risk population of EBV negative recipients. Therefore, an efficient and safe preventive treatment is still lacking to decrease PTLD incidence.
Rituximab, has been already proposed in stem cell transplant recipients as a preemptive therapy in patients with a persistent EBV viremia independently of their EBV status. A pilot study was performed in EBV negative kidney transplant recipients but in a very small population. Schachtner60 reported the cases of 5 EBV negative recipients receiving kidney from EBV positive donors after a treatment with Rituximab. Only 2 patients showed a seroconversion and no patients developed neither a viremia nor a PTLD after 49 months of follow-up.
The main objective of the investigators study is to evaluate the efficacy of early infusion of Rituximab in the prevention of EBV primary infection and post-transplant lymphoproliferative disorder (PTLD) occurrence in adult EBV negative kidney transplant recipients transplanted with an EBV positive donor.

Every year, 12500 primary renal cell carcinoma (RCC) are diagnosed in France. Metastases occur in half of RCC patients.
Management of metastatic RCC is based on systemic treatments (targeted therapies/immunotherapy). However, resistance to systemic treatment is frequent. In case of progression, usual therapeutic attitude is initiating another systemic therapy.
Because of the emergence of resistant tumor clonal cells, some patients progress only on few sites while the rest of tumor burden is controlled. In this setting named oligoprogressive disease \[isolated progression of \<3-5 metastase(s)\], ablative treatments of these evolving metastatic sites could allow a disease control and a reduced risk of new metastases occurrence by tumor-cell reembolization. Such strategy is challenging to prolong ongoing systemic treatment and delay further lines.
Although RCC was considered radioresistant and radiotherapy with conventional fractionation was mainly used for palliation of symptoms, stereotactic radiotherapy (SRT), by delivering high dose in one or few fractions, allows local control for about 90% of RCC metastases through various radiobiological pathways. Furthermore, some data suggest that high-dose focal irradiation of RCC could induce a systemic antitumor response mediated by immunologic effectors(1). This phenomenon ("abscopal effect") could be enhanced in patients under immunotherapy, including anti-PD1.
Several retrospective studies and one non-randomized phase-II study highly suggest the interest of SRT as focal ablative treatment in RCC oligometastases with excellent local control rates and low toxicity(2,3).
Furthermore, the multicentric retrospective study the sponsor recently conducted within the GETUG group among 101 metastatic RCC patients with oligoprogression under systemic therapy highlighted that SRT on progressive sites provided a median of 8.6-month progression-free survival and allowed to continue current systemic line for 10.5 months.
However, to date, there are no prospective data assessing the interest of SRT for management of oligoprogressive metastatic RCC.
The sponsor aim to prospectively evaluate the interest of SRT as a therapeutic strategy for local control of oligoprogressive metastatic RCC under ongoing systemic treatment, and consequently delay subsequent systemic treatment.

This phase IV trial is evaluating whether morning versus afternoon administration of standard of care immunotherapy impacts its effectiveness in treating patients with solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Immunotherapy with monoclonal antibodies may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Circadian rhythm refers to the internal biological clock in which various processes in the body, including immune cell activity, are controlled by the time of day. Exactly how this works is not fully understood, and the researchers want to see if circadian rhythm control of the immune system can influence response to immunotherapy based on whether it is given in the morning (before 11:00 am) or afternoon (12:00pm). The time of day that immunotherapy is given (morning versus afternoon) may impact the effectiveness in treating patients with advanced or metastatic solid tumors.

According to the 2020 global cancer statistics, renal carcinoma ranks as the fourteenth most common malignant tumor worldwide. In 2020, there were 431,288 new cases and 179,368 deaths from renal cancer, and both the incidence and mortality rates are projected to continue rising by 2025. Early non-invasive diagnosis of clear cell renal cell carcinoma (ccRCC) is crucial for improving prognosis. Nuclear medicine molecular imaging offers the advantages of real-time, dynamic, and non-invasive detection of lesions throughout the body. However, there is currently a lack of highly efficient and targeted molecular probes for early and accurate diagnosis of this tumor in clinical practice.
The high expression of CAIX plays a central role in the pathogenesis of renal cancer by altering cellular metabolism, inducing angiogenesis, promoting epithelial-mesenchymal transition (EMT), invasion, and metastatic spread. CAIX is highly expressed in 95% of ccRCC cases. In fact, CAIX expression levels have been reported as an independent predictor of survival in advanced ccRCC. Moreover, CAIX expression in normal tissues is limited, primarily restricted to the stomach, the basolateral aspects of proliferating small intestinal crypt epithelial cells, and the gallbladder. Therefore, the differential expression of CAIX between ccRCC tumors and normal tissues highlights its potential as a robust target for nuclear medicine molecular probe research and development in ccRCC.
This study utilized high-throughput screening to identify small molecules with high affinity for CAIX. These molecules were subsequently cyclized and modified to enhance their in vivo stability. A bifunctional chelator, H3RESCA, was introduced at the C-terminus to construct the small-molecule compound RESCA-CAIX-LT. PET probes were prepared by radiolabeling with 68Ga or 18F, and their diagnostic efficacy for renal cancer was investigated. Small-animal PET imaging initially demonstrated that the probe exhibits high affinity and excellent imaging performance. The modifications also altered the in vivo metabolic profile of the original design, reducing non-specific uptake in organs such as the stomach, small intestine, and gallbladder. Furthermore, toxicological experiments confirmed the probe's high safety profile and in vivo stability.
