The goal of this prospective, multicenter, randomized controlled trial is to compare the clinical efficacy and safety of intra-operative dual laparoscopy and neo-rectoscopy (IDLnR) versus conventional laparoscopy (CL) in patients with bowel endometriosis (BE) undergoing surgery. The primary objective is to assess differences in postoperative bowel function improvement at 6 months between the two groups. The main questions it aims to answer are: Is there a significant difference in postoperative bowel function (primary endpoint) at 6 months postoperatively between IDLnR and CL groups? Do the two groups differ in secondary outcomes, including efficacy indicators (LARS score/cure rate/improvement rate, CRADI-8, Wexner score, GIQLI, EHP-30, VAS pain reduction) and safety indicators (30-day severe complications, antibiotic use intensity, hospital stay \>7 days)? Researchers will randomize BE surgical patients to IDLnR or CL groups, then compare the above primary and secondary endpoints to evaluate IDLnR's clinical value. Participants will undergo either IDLnR or CL surgery for BE lesions, and be followed up to assess bowel function, quality of life, pain, and safety outcomes as specified. This study will fill evidence gaps for IDLnR in BE surgery, support its standardized application, optimize BE treatment strategies, and aim for complete lesion resection, preserved intestinal function, and improved long-term patient quality of life.

Cervical cancer ranks fourth globally in both incidence and mortality rates, making early diagnosis and treatment of great significance. For early-stage cervical cancer, surgery remains the primary treatment approach. According to the latest NCCN guidelines, patients with Stage IA2 or IB1 cervical cancer confirmed by cone biopsy who meet Concerv or SHAPE criteria no longer require type C/B hysterectomy. Instead, they may undergo type A hysterectomy with reduced surgical margins. However, patients with Stage IB2 or IIA1 tumors measuring 2-4 cm still require radical hysterectomy (type C). Radical hysterectomy carries high risks of postoperative complications and significantly impairs quality of life, including major vascular injury, urinary tract damage and dysfunction, lymphatic complications, and sexual dysfunction. Therefore, there is an imperative need to explore alternative or refined treatment approaches for Stage IB2/IIA1 cervical cancer that ensure survival outcomes while reducing surgical morbidity and improving quality of life. Neoadjuvant therapy followed by scale-reduced surgery may represent a feasible strategy. Both immune escape and angiogenesis are core drivers of tumorigenesis and progression. Combined immunotherapy and anti-angiogenic therapy have demonstrated favorable antitumor efficacy and manageable safety profiles across multiple tumor types. Ivonescimab is a novel humanized tetrameric IgG-scFv bispecific antibody targeting PD-1 and VEGF. Mechanistically, PD-1 blockade reverses T-cell suppression while VEGF inhibition curbs neovascularization, yielding synergistic therapeutic enhancement. This agent has shown promising efficacy and safety in advanced non-small cell lung cancer, hepatocellular carcinoma, and recurrent glioblastoma, though clinical data in cervical cancer remain absent. Therefore, this prospective exploratory study aims to evaluate the efficacy and safety of neoadjuvant Ivonescimab combined with paclitaxel and cisplatin followed by type A hysterectomy for stage IB2/IIA1 cervical cancer. The findings may provide novel insights for optimizing treatment paradigms-ensuring survival outcomes while preserving quality of life.

Currently, the survival rate of locally advanced cervical cancer is low, posing a significant challenge in the treatment of cervical cancer. Radical chemoradiotherapy is considered the standard treatment for patients with locally advanced cervical cancer. However, 23.3% to 34.4% of patients still experience recurrence or subsequent metastasis. Radical surgery following neoadjuvant chemotherapy is an alternative to concurrent chemoradiotherapy, but it also has limitations: for approximately 9.8% to 30.6% of patients who do not respond to neoadjuvant chemotherapy, effective local treatment may be delayed. Additionally, more than 30% of patients still require adjuvant radiotherapy or chemoradiotherapy after surgery, significantly increasing the risk of complications. Therefore, there is an urgent need to explore alternative or improved treatment methods for neoadjuvant chemotherapy in locally advanced cervical cancer. An increasing number of women are being diagnosed with cervical cancer during their childbearing years, many of whom have a desire to preserve their fertility. For selected patients with stage IB2 cervical cancer, options include abdominal radical trachelectomy or radical trachelectomy following neoadjuvant chemotherapy. However, compared to conservative surgeries such as conization or partial cervical resection, radical trachelectomy is associated with less favorable fertility rates and pregnancy outcomes, with significantly higher rates of infertility, miscarriage, and preterm birth. For patients with stage IB3 or IIA1-IIA2 cervical cancer, the current standard surgical approach is radical hysterectomy, which does not preserve fertility. Current research suggests that neoadjuvant chemotherapy can shrink tumor size, decrease lymph node and distant metastases, and reduce the need for postoperative adjuvant radiotherapy. This offers hope for young cervical cancer patients who wish to preserve fertility, as it may reduce tumor size, thereby allowing for less extensive fertility-sparing surgery, improving pregnancy outcomes, or even making fertility-sparing surgery a viable option. In recent years, immunotherapy has gradually become a research hotspot in cancer treatment. Anti-PD-1/PD-L1 monoclonal antibodies, as a type of immunotherapy drug, have demonstrated promising anti-tumor efficacy and low side effects in clinical trials. Iparomlimab and Tuvonralimab is a novel therapeutic biological product targeting both PD-1 and CTLA-4. It is composed of two engineered monoclonal antibodies (anti-PD-1 and anti-CTLA-4) expressed in a fixed ratio and has shown significant efficacy in cervical cancer patients. Therefore, given the urgent need to improve neoadjuvant therapy for locally advanced cervical cancer and fertility-preserving neoadjuvant therapy for early-stage cervical cancer patients, this study is being conducted to explore and evaluate the efficacy and safety of Iparomlimab and Tuvonralimab combined with paclitaxel and cisplatin as neoadjuvant therapy for cervical cancer. Additionally, the study aims to investigate the relationship between tumor-related biomarkers and the risk of recurrence.

Screening patients who meet the criteria for peripheral blood mononuclear cell (PBMC) isolation and cell preparation. Based on the status of cell preparation and mutual agreement between the researcher and the participant, the date of reinfusion (Day 0) is determined. From Day -5 to Day -3, the participant receives a conditioning regimen with cyclophosphamide and antithymocyte globulin. After recovery for two days (Day -2 and Day -1), on Day 0, the participant receives reinfusion of BZE2203 (dose determined according to the dose-escalation requirements). The safety observation period lasts for 28 days, and clinical efficacy is assessed from Day 28 to Day 34. After comprehensive judgment, the second course of cell therapy is selected. Follow-up observations and evaluations are conducted once every three months, with follow-up visits once a year and telephone follow-ups once every two months.
