Nephron-sparing Treatment of Tislelizumab + Nab-Paclitaxel for Renal Pelvic Cancer

This study is designed as an open-label, single-arm, single-center, phase II clinical trial, aiming to evaluate the efficacy of nephron-sparing treatment combining Tislelizumab and Nab-Paclitaxel for HER-2 expressing renal pelvic cancer (RPC) . Patients enrolled will receive 2-3 cycles of Tislelizumab in combination with Nab-Paclitaxel every 3 weeks and then undergo evaluation. Patients who achieve all of the following criteria of "well response and tolerance" will receive further maintenance treatment: (1)The patient achieves a complete response (CR) or partial response (PR) according to the RECIST 1.1 criteria, indicating that the tumor is well-controlled. (2) If the patient has residual lesions, it should be confirmed by the clinical physician that these lesions can be eliminated through laser ablation via ureteroscopy. (3)The patient has not experienced any treatment-related adverse events (TRAEs) that warrant discontinuation of therapy during systemic treatment. (4)The patient is willing to undergo further maintenance therapy. If the patient meets all the criteria above, ureteroscopic biopsy should be performed. If residual lesions are detected under the ureteroscope, endoscopic intervention (e.g., laser ablation, cryoablation) should be carried out simultaneously to eliminate these residual lesions. Patients who meet the above criteria will proceed with no less than 2 cycles of maintenance systemic therapy (Tislelizumab + Nab-Paclitaxel). Patients who do not meet the criteria will be excluded from the study and are recommended to undergo salvage radical nephroureterectomy (RNU) as soon as possible. One-year Nephron-Sparing Survival (1 year-NSS): Defined as the absence of surgical indications for nephrectomy due to progression or recurrence of upper urinary tract urothelial carcinoma, distant metastasis caused by the primary upper urinary tract tumor, or death from any cause within 1 year from the initiation of treatment. Treatment-related adverse events (TRAEs) will be recorded and evaluated according to CTCAE 5.0.

Application of PD-1 Inhibitors Combined With Tenofovir, Chidamide and Lenalidomide in the Treatment of EBV-associated Diseases.

Currently, treatment options for Epstein-Barr virus (EBV) infection are limited, with unsatisfactory efficacy and no established standard therapy. Therefore, our center is conducting a prospective, multicenter, single-arm clinical trial to evaluate the efficacy and safety of PD-1 inhibitor in combination with tenofovir, chidamide, and lenalidomide in patients with EBV infectious diseases, aiming to provide a more effective and safer therapeutic option for EBV infectious diseases.

Application of PD-1 Inhibitors, Tenofovir, Chidamide, and Lenalidomide in Relapsed/Refractory EBV-associated Lymphoproliferative Disorders.

This study is a prospective, multicenter, single-arm clinical trial designed to evaluate the efficacy and safety of PD-1 inhibitor combined with tenofovir, chidamide, and lenalidomide in the treatment of relapsed or refractory Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPDs). The primary endpoint is the overall response rate (ORR) at 3 months, including complete response (CR) and partial response (PR). Secondary endpoints include overall survival (OS), progression-free survival (PFS), as well as safety and tolerability assessments. Eligible patients must have histologically confirmed EBV-positive B-cell or T/NK-cell LPDs with measurable lesions. This combination regimen targets multiple mechanisms, including inhibition of EBV replication, activation of the immune system, and enhancement of antitumor effects, aiming to provide an innovative therapeutic strategy for this challenging disease.

Neoadjuvant Toripalimab Plus Celecoxib for dMMR/MSI-H Locally Advanced Colorectal Cancer

Several Phase II studies have demonstrated the feasibility, effectiveness, and good tolerability of neoadjuvant immune checkpoint inhibitor (ICI) treatment for localized dMMR colorectal and rectal cancers. The significant clinical and pathological complete response rates offer the possibility of avoiding surgical resection. dMMR colorectal cancers are generally larger and more advanced than pMMR tumors, often requiring more extensive surgery with associated risks such as anastomotic leakage, ureteral injury, and infection. If oncological outcomes are not affected (requiring long-term follow-up), non-surgical treatment becomes an attractive option for localized dMMR colorectal cancer. Moreover, pelvic radiotherapy, the standard for locally advanced rectal cancer, causes both short-term and long-term adverse effects (e.g., bowel and bladder dysfunction, fistula, infertility), significantly impacting quality of life. Total mesorectal excision also carries risks of complications and sexual dysfunction, often requiring a stoma, making organ preservation a more urgent need for rectal cancer patients. Phase II trials and the international "watch-and-wait" database have confirmed the feasibility and safety of organ preservation for pMMR locally advanced rectal cancer. Therefore, the high clinical and pathological complete response rates achieved by neoadjuvant immunotherapy for dMMR/MSI-H rectal cancer offer promising prospects for non-surgical treatment.
