The goal of this clinical trial is to evaluate the biodistribution, radiation dosimetry, safety, and time-dependent image quality of \^68\^Ga-EV203 injection in patients with hematological malignancies (multiple myeloma, non-Hodgkin lymphoma, or acute myeloid leukaemia), aged 18-75 years, who are able to lie still for 0.5 h and have no contraindications (e.g., pregnancy, recent radiotherapy, etc.). The main questions it aims to answer are: What are the biodistribution (organ uptake, %ID, SUV) and radiation absorbed doses (mGy/MBq) of \^68\^Ga-EV203 in target organs and the whole body? What is the safety profile of \^68\^Ga-EV203, as measured by adverse events and serious adverse events? How does the PET/CT image quality differ between the 30-, 60-, 90-, and 120-minute time points after injection? If there is a comparison group: Researchers will compare the positive percent agreement (PPA) and positive predictive value agreement (PPrA) of \^68\^Ga-EV203 PET/CT against \^18\^F-FDG PET/CT to see if the new tracer offers comparable or superior diagnostic performance in detecting CXCR4-positive lesions. Participants will: Receive a single intravenous injection of 74-296 MBq of \^68\^Ga-EV203. Undergo whole-body PET/CT scans at 30 min, 60 min, 90 min, and 120 min post-injection on the same day. Return within 3-7 days (but at least 2 days later) for a standard \^18\^F-FDG PET/CT scan after fasting for ≥5 h. Attend a safety follow-up visit at day 8-14 for physical examination, vital signs, and laboratory tests (blood count, coagulation, and biochemistry).

Ovarian cancer is one of the most fatal malignant tumors that threaten women's health. The incidence rate is the third place among the female reproductive system malignant tumors, and the mortality rate ranks the first in gynecologic malignancies, the majority of patients have advanced diseases at the time of diagnosis. This observational study is to evaluate the safety and efficacy of senaparib in ovarian cancer patients under real conditions, especially in various subgroups of ovarian cancer patients, in order to provide information about treatment modes for ovarian cancer patients in real-world diagnosis and treatment。

This is a prospective, single-arm, single-center, open-label clinical study, aiming to evaluate the efficacy and safety of CAR-T combined with ASCT in the treatment of relapsed/refractory large B-cell lymphoma with high-risk factors.

This is a prospective, multicenter Phase 2 clinical trial named the MALT-RO study, evaluating ultra-low-dose radiation therapy followed by orelabrutinib as first-line treatment for adults with Stage I-II MALT lymphoma. The study aims to determine the efficacy and safety profile of this sequential regimen. Eligible participants aged 18 years or older with histologically confirmed MALT lymphoma, measurable lesions, no prior systemic anti-lymphoma therapy, adequate organ function, and an ECOG performance status of 0-1 will receive 4Gy ultra-low-dose radiation (2Gy daily for 2 consecutive days) followed by oral orelabrutinib 150mg once daily for up to 6 cycles (28 days per cycle). Patients with partial response or stable disease after 6 cycles may continue orelabrutinib monotherapy for up to 12 cycles or until disease progression. All participants will undergo regular safety monitoring, tumor assessments, and long-term follow-up every 3 months to evaluate treatment durability. This treatment strategy is designed to improve efficacy and achieve more favorable outcomes compared with standard approaches for MALT lymphoma, while minimizing treatment-related toxicities such as long-term organ damage, xerostomia, cataracts, and other complications related to conventional standard-dose radiation, thereby offering a well-tolerated, convenient, targeted therapeutic option for patients with MALT lymphoma under strict ethical oversight in accordance with the Declaration of Helsinki and Chinese Good Clinical Practice guidelines.

This study is a prospective, single-center, open-label, single-arm clinical trial to assess the safety and efficacy of umbilical cord blood in cancer treatment-induced thrombocytopenia (CTIT) patients. It plans to recruit subjects aged 12 to 65 years old with CTIT. The study involves intravenous infusion of umbilical cord blood, with platelet transfusion as supportive therapy if necessary. The trial consists of three phases: screening (baseline assessments and enrollment), treatment (umbilical cord blood infusion), and follow-up (blood routine tests at Days 3, 7, 14, and 28 post-treatment to record platelet counts, first response time, maximum and minimum values, and calculate efficacy rates while observing changes in thrombocytopenia grading). A total of 25 subjects will be enrolled, and they will undergo evaluation for safety and efficacy based on treatment-related adverse events, GVHD incidence, and hematological improvements.

This study adopts a multicenter, natural selection, observational design, and plans to enroll patients with HER-2 positive advanced or metastatic breast cancer treated at approximately 20 research centers nationwide. Patients with de novo stage IV disease or those with recurrent metastatic breast cancer who have not previously received trastuzumab, as well as patients with brain metastases, will be included for separate stratified efficacy analysis and will not be included in the overall analysis. The study plans to enroll effective data from 600 HER-2 positive advanced or metastatic breast cancer patients, who will be naturally allocated in a 1:1 ratio to either Group A (switching from HP + chemotherapy to HPy + chemotherapy) or Group B (switching from HPy + chemotherapy to HP + chemotherapy), with each group comprising approximately 300 patients. If first-line treatment fails, patients will switch to the alternative regimen in second-line treatment. All patients will continue treatment until disease progression, intolerable toxicity, or other reasons lead to discontinuation, with the number of treatment cycles recorded. The study is divided into three phases: screening/baseline period, treatment period (treatment period 1 + treatment period 2), and survival follow-up period. If patients develop intolerance to taxanes during treatment, clinicians may select alternative chemotherapy regimens such as vinorelbine, capecitabine, or eribulin based on clinical judgment. During the treatment period, patients will be followed up every two cycles, during which clinical data will be collected, including disease status assessments, laboratory tests, study drug usage, concomitant medications, and adverse events. After chemotherapy completion or treatment discontinuation, subsequent maintenance therapy, such as continued dual-targeted maintenance, may be administered by clinicians based on clinical needs until disease progression or intolerable toxicity occurs. Survival follow-up will be conducted every three months (for up to three years), with patient survival status recorded.

This is a prospective, single-Arm, phase II clinical study evaluating the efficacy and safety of thiotepa in combination with pirtobrutinib (a BTK Inhibitor) and sintilimab (a PD-1 Inhibitor) for frail or relapsed/refractory primary or secondary central nervous system lymphoma.It includes screening phase， induction therapy phase, and maintenance therapy phase.The screening period is defined as within 14 days prior to the first dose.Induction Treatment Phase: Enrolled subjects will receive a combination regimen of thiotepa, pirtobrutinib, and sintilimab. Treatment is administered in 21-day cycles for up to 6 cycles. Patients who achieve a disease response may proceed to consolidation therapy with either autologous hematopoietic stem cell transplantation or whole-brain radiotherapy at the investigator's discretion.Maintenance Treatment Phase: For patients who do not receive consolidation therapy with autologous transplantation or whole-brain radiotherapy, maintenance treatment with pirtobrutinib plus sintilimab will be initiated (for up to 1 year). Patients who receive any consolidation therapy will not proceed to maintenance treatment.Treatment response will be assessed throughout the study using the International Primary CNS Lymphoma Collaborative Group (IPCG) criteria. The trial will monitor patient survival data, objective response rate (ORR), and safety parameters.Upon discontinuation of study treatment or completion of the 1-year treatment period, subjects will enter the follow-up phase. During follow-up, radiographic assessments (contrast-enhanced CT of the involved site is recommended) will be performed according to the following schedule: every 3 months for the first 2 years, every 6 months from Year 3 to Year 5, and annually after 5 years, until the end of the follow-up period. For subjects who have not withdrawn consent, survival information (including date and cause of death, subsequent anti-tumor therapies, etc.) will be collected every 3 months via telephone and/or clinical visit.

Ovarian cancer exhibits the highest mortality rate among gynecological malignancies. Currently, the combination of paclitaxel and carboplatin remains the standard first-line chemotherapy regimen for neoadjuvant or postoperative treatment of ovarian cancer. However, conventional paclitaxel, due to the addition of polyoxyethylated castor oil solubilizer, may induce various adverse reactions beyond chemotherapeutic toxicity, such as hypersensitivity, toxic renal injury, neurotoxicity, and cardiovascular toxicity. Therefore, exploring optimized treatment regimens to provide patients with new therapeutic options is imperative. HER2 is a protein encoded by the ERBB2 gene that regulates cell survival, proliferation, and differentiation. HER2 gene amplification and/or protein overexpression are observed in 18%-35% of mucinous ovarian cancers. A meta-analysis involving over 5,000 ovarian cancer cases revealed that HER2 overexpression correlates with reduced overall survival (OS) and progression-free survival (PFS), suggesting its potential as a biomarker for poor prognosis. The emergence of novel antibody-drug conjugates (ADCs) has brought new hope for anti-HER2 therapy in ovarian cancer, such as Disitamab Vedotin (RC48). Preliminary results from the PRaG3.0 trial presented at the 2023 ASCO Annual Meeting showed an ORR of 66.7% in six HER2-expressing gynecological cancer patients treated with RC48 combined with radiotherapy and immune checkpoint inhibitors (ICIs). Updated data from the RC48-C018 study demonstrated an ORR of 36.4%, median duration of response (mDoR) of 5.52 months, mPFS of 4.37 months, and 12-month OS rate of 66% in 22 cervical cancer patients. RC48 exhibited promising efficacy and manageable safety in recurrent/metastatic HER2-expressing (IHC 1+/2+/3+) cervical cancer. Regarding safety, the GOG-158 study reported pronounced hematologic toxicity with carboplatin-paclitaxel in advanced ovarian cancer: grade 3/4 leukopenia (\>50%), thrombocytopenia (\>30%), and neutropenia (\>80%). Conversely, a retrospective study of RC48 combined with platinum ± bevacizumab in HER2-mutated NSCLC patients showed an ORR of 71.4% with no dose reductions or discontinuations due to adverse events. Thus, RC48-platinum combinations may offer a lower-toxicity alternative. Thus the investigators designed this trial to evaluate the efficacy and safety of RC48 combined with carboplatin in HER2-expressing advanced ovarian cancer.

Laryngeal masks are core devices for supraglottic airway management, and the accuracy of their anatomical position directly impacts ventilation safety and the incidence of complications. Despite their wide clinical application, gaps remain in understanding their in vivo anatomical characteristics. This study aims to evaluate the in vivo anatomical features (e.g., insertion depth, anatomical alignment, tissue compression) of three laryngeal masks (LMA Supreme, I-gel, GMA-Tulip) using CT scanning in anesthetized patients undergoing CT interventional therapy, providing anatomical evidence for optimized laryngeal mask selection and complication prevention.

The integrity and functional stability of pharyngolaryngeal anatomical structures are critical for airway management, and the dynamic changes of key structures (e.g., pyriform sinus, cricoid cartilage lamina) during swallowing directly relate to the design and clinical safety of laryngeal masks. This observational study aims to investigate the real-time dynamic changes and physiological movement patterns of normal pharyngolaryngeal structures during barium swallow using routine barium meal examination imaging. The findings will provide anatomical and physiological evidence for optimizing laryngeal mask design and improving its anatomical fit with the pharynx and larynx.

Primary Objectives： Evaluate the complete response rate (CR rate) and safety of short - course radiotherapy combined with ivonesimab (AK112) in patients with pMMR/MSS mid - low rectal cancer. Secondary Objectives： Evaluate treatment - related toxic reactions, the quality of life, long - term prognosis (local control \[LC\], disease - free survival \[DFS\] and overall survival \[OS\]). Patients will : Receive Radiotherapy: Pelvic IMRT or VMAT, DT 25Gy/5Fx. One week after radiotherapy, begin treatment with Ivorsimab (AK112) at a dose of 20mg/kg by intravenous drip on day 1. One cycle is 21 days, and a total of 6 cycles are to be carried out. Evaluate the curative effect after 3 cycles of treatment. Patients with progressive disease (PD) will withdraw from the study, and other treatment plans will be adjusted in a timely manner. Patients with CR/PR/SD will continue treatment for another 3 cycles. Conduct a comprehensive assessment after 6 cycles of treatment. Patients who achieve cCR can choose the watch - and - wait approach. For patients who do not achieve cCR, TME surgery is recommended. Decide whether to perform adjuvant chemotherapy based on the postoperative pathological findings.

Based on our previous single-arm Phase Ib study (CRIS trial, NCT06303583), we observed that neoadjuvant chemoradiotherapy followed by immunotherapy (nCRIT) significantly increased the pathological complete response (pCR) rate, achieving approximately 60% in locally advanced esophageal squamous cell carcinoma(ESCC). We plan to initiate a multicenter, prospective, randomized phase II trial designed to compare the efficacy and safety of neoadjuvant chemoimmunotherapy (nCIT) versus neoadjuvant chemoradiotherapy followed by immunotherapy (nCRIT) in treating esophageal squamous cell carcinoma. The primary study population includes patients with operable or potentially operable thoracic ESCC classified as cT3-4aN0 or T2-4aN+ based on endoscopy, enhanced chest and abdominal CT, and whole-body PET scans. Eligible participants are aged 18-75 years with an ECOG performance status of 0-1. Qualified patients will be randomly assigned in a 1:1 ratio to either the nCRIT group or the nCIT group. Patients in the nCRIT group will receive neoadjuvant concurrent chemoradiotherapy: radiation therapy will be administered using IMRT or VMAT with involved-field irradiation at a dose of PTV 41.4 Gy/23 fractions/31 days. Chemotherapy will consist of weekly administration of paclitaxel (albumin-bound) 50 mg/m² and carboplatin (AUC=2) for five weeks, given on the days of radiotherapy. Patients who do not progress on CT and meet immunotherapy criteria will receive fixed-dose tislelizumab (200 mg IV) on days 8 and 29 after chemoradiotherapy, followed by minimally invasive esophagectomy four weeks after completing immunotherapy. Patients in the nCIT group will receive two cycles of TC chemotherapy combined with immunotherapy, specifically paclitaxel (albumin-bound) 100 mg/m² on days 1, 8, 15 or 260mg/m² d1, carboplatin (AUC=5) on days 1, and tislelizumab (200 mg) on days 1. Minimally invasive esophagectomy will be performed 4-6 weeks after completing chemotherapy, and adjuvant immunotherapy is recommended for one year after surgery. The primary endpoint of the study is the pathological complete response (pCR). Secondary endpoints include treatment safety, CT imaging response rate, R0 resection rate, major pathological response (MPR), 2-year event-free survival (EFS), 2-year overall survival (OS) in the intention-to-treat (ITT) population, and analysis of treatment failure reasons.
