Ovarian Cancer (OvCa)

Colorectum is the most common site of metastasis in ovarian cancer. Regarding intestinal surgery, there is controversy over whether to choose bowel resection or tumor removal, and currently, there are no prospective randomized controlled studies comparing the oncological safety of these two surgical approaches. This study is a prospective randomized trial aimed at comparing the efficacy of rectosigmoid resection versus rectosigmoid-preserving lesion excision in advanced ovarian cancer surgery.

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。

Ovarian, fallopian tube, and peritoneal cancers are often diagnosed at an advanced stage, requiring chemotherapy. Recently, the standard treatment, platinum-based chemotherapy plus PARP inhibitors, has extended disease-free survival (PFS). However, most patients eventually develop resistance to PARP inhibitors and become unresponsive to conventional treatments. Therefore, an effective standard treatment for patients who relapse after PARP inhibitor resistance has not yet been established. Meanwhile, HER2 protein expression has been identified in some patients, drawing attention as a new therapeutic target. Trastuzumab deruxtecan (T-DXd), an antibody-drug conjugate (ADC) targeting HER2, has already demonstrated efficacy and safety in other HER2-positive cancers. This study aimed to explore the potential of T-DXd as a new treatment option by evaluating the efficacy and safety of T-DXd in patients with ovarian, fallopian tube, and peritoneal cancer who relapsed after PARP inhibitor treatment and who express HER2. Participants will: * Arm A: T-DXd +/- Bevacizumab, IV, every 3weeks * Arm B: Platinum-based chemotherapy +/- Bevacizumab, IV

In this 2-arm, non-randomized, phase II trial, the investigators will evaluate the efficacy and safety of comprehensive multimodal prehabilitation (CMMP) alone or in combination with planned neoadjuvant (NAT) in pre-frail/frail patients with probable/proven pancreaticobiliary, ovarian, kidney, or bladder cancer prior to elective major cancer surgery (EMCS).

The goal of this clinical trial is to investigate if CALM-TF (Trauma-Focused Managing Cancer and Living Meaningfully) is effective in treating traumatic stress symptoms in women with advanced ovarian cancer. It will also learn whether the efficacy differs at new diagnosis versus at recurrence. The main questions it aims to answer are: 1. What is the effectiveness of CALM-TF in reducing traumatic stress symptoms in patients with newly diagnosed or recurrent advanced ovarian cancer, as measured at 3 and 6 months? 2. What are the effects of CALM-TF on depression, quality of life, and patient-perceived benefit of the intervention compared to usual care alone? 3. What are patient perceptions of their care experiences as explored through qualitative interviews? Researchers will compare CALM-TF to usual standard of care (which includes regular conversations with medical teams and meetings with social workers) to see if CALM-TF works to treat traumatic stress. Participants will: * Receive 3-6 sessions of CALM-TF over 3-6 months (45-60 minutes each) via video call, telephone, or in-person based on preference, OR receive usual care only * Complete questionnaires at baseline, 3 months, and 6 months * Continue to receive their standard cancer care throughout the study * Some participants may be invited to participate in qualitative interviews at 6 months

This study is a Prospective, Single-arm, Phase II clinical trial. The purpose of this study is to find out if taking Etoposide Capsules combined With Bevacizumab and Iparomlimab and Tuvonralimab is safe and works well for people with platinum-resistant or platinum refractory ovarian cancer . Researchers will look at the Progression-Free Survival, Objective Response Rate, Overall Survival, safety, and any side effects.

Involvement of the infundibulopelvic ligament in ovarian cancer may be associated with decreased survival and related to paraaortic lymph node metastasis

The goal of this observational study is to determine the urinary proteomic characteristics in women with and without ovarian cancer. The main questions it aims to answer are: 1. What is the difference in urinary protein composition between patients with ovarian cancer and those without it? 2. Can these differences in urinary protein composition aid in the diagnosis of ovarian cancer? 3. Are urinary protein markers associated with tumor burden in urine samples from patients with ovarian cancer? 4. Can urinary protein markers be used for disease surveillance in ovarian cancer patients?
