Active clinical trials for "Peritoneal Neoplasms"

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel drug-delivery system developed to deliver, effectively and safely, small doses of cytotoxic agents into peritoneal tumor deposits. It is currently used for palliation and for down-staging of patients who are non-eligible for cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC). The aim of this study is to evaluate the efficacy of PIPAC used in neoadjuvant setting to enhance the response of patients with colorectal peritoneal metastasis when combined with neoadjuvant systemic therapy for patients eligible to CRS/HIPEC prior to planned surgery.

This is a phase II, single arm, open-label, single-center study to evaluate the efficacy and safety of Surufatinib combined with Toripalimab in patients with peritoneal metastatic carcinoma of gastrointestinal or primary peritoneal cancer.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is evaluating DNA mutations in predicting the effect of external-beam radiation therapy in patients with early breast cancer, localized prostate cancer, or gynecologic cancer.

This phase II clinical trial studies the safety and effect of Gimatecan in patients with platinum-resistant recurrent epithelial ovarian, fallopian tube or peritoneal cancer. The chemotherapy will be given every four weeks.This study is a single-arm, multi-center research design.

This research trial studies chitinase 3-like 1 (cartilage glycoprotein-39) (YKL-40) in serum samples from patients with newly diagnosed stage III-IV ovarian epithelial, primary peritoneal cavity, or fallopian tube cancer receiving chemotherapy. Studying samples of serum in the laboratory from patients receiving chemotherapy may help doctors learn more about the effects of chemotherapy on cells. It may also help doctors understand how well patients respond to treatment.

Colorectal Cancer (CRC) is the third most common cancer and the fourth most common cause of cancer-related death worldwide. CRC frequently gives rise to transcoelomic spread of tumor cells in the peritoneal cavity, which ultimately leads to Peritoneal Carcinomatosis (PC). A new loco-regional treatment modality combines Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Peroperative Chemotherapy (HIPEC). The current HIPEC dosing regimens for the treatment of colorectal PC can be divided into body surface area (BSA)-based protocols and concentration-based protocols. Most groups currently use a drug dose based on calculated BSA (mg/m2) in analogy to systemic chemotherapy regimens. These regimens take BSA as a measure for the effective contact area, represented as the peritoneal surface in the formula for dose intensification. However, an imperfect correlation exists between actual peritoneal surface area and calculated BSA. Sex differences, but also altered pathophysiological characteristics or frequent complications in patients (ascites) are responsible for differences in peritoneal surface areas, which in turn affect absorption characteristics. This takes us away from the initial homogenous drug concentration desired, increasing the variability in the systemic and tumor exposure to the drug. Pharmacokinetic changes induced by the volume of chemotherapy solution with constant drug dose, administered intraperitoneally, have already been reported. This resulted in less precise predictions of the toxicity associated with the treatment. By contrast, some groups use a totally different dosimetry regimen based on concentration. From a pharmacologic point of view, the big advantage of a concentration-based system is that the residual tumor nodules after CRS are exposed to a constant diffusional force and, thus, cytotoxicity. Unfortunately the prize to be paid for a better prediction of the efficacy of the IP chemotherapy is a high unpredictability of the levels of plasmatic cancer chemotherapy and, thus, toxicity. This randomised non-blinded phase III clinical trial will be the first trial to pharmacologically evaluate the two dosing regimens, BSA-based and concentration-based, both applied as standard of care in current practice.

RATIONALE: Drugs used in chemotherapy, such as liposome-encapsulated doxorubicin citrate and gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether liposome-encapsulated doxorubicin citrate is more effective when given together with or without gemcitabine hydrochloride in killing tumor cells. PURPOSE: This randomized phase II trial is studying liposome-encapsulated doxorubicin citrate given together with gemcitabine hydrochloride to see how well it works compared with liposome-encapsulated doxorubicin citrate alone in treating patients with ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cavity cancer.

This randomized phase III trial studies paclitaxel and carboplatin see how well they work compared with paclitaxel and ifosfamide in treating patients with fallopian tube, or peritoneal cavity cancer that is newly diagnosed, persistent, or has come back (recurrent). Drugs used in chemotherapy, such as paclitaxel, carboplatin, and ifosfamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether paclitaxel is more effective when given with carboplatin or ifosfamide in treating patients with uterine, ovarian, fallopian tube, or peritoneal cavity cancer.

RATIONALE: Drugs used in chemotherapy, such as carboplatin, gemcitabine, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known which treatment regimen may kill more tumor cells. PURPOSE: This randomized phase II trial is studying how well giving one of two chemotherapy regimens containing carboplatin, gemcitabine, and paclitaxel works in treating patients undergoing surgery for newly diagnosed primary stage IIIC or stage IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Hyperthermia therapy kills tumor cells by heating them to several degrees above body temperature. Combining hyperthermia with chemotherapy may kill more tumor cells. It is not yet known if chemotherapy is more effective with or without whole-body hyperthermia therapy in treating gynecologic cancer. PURPOSE: Randomized phase II/III trial to compare the effectiveness of chemotherapy with or without whole-body hyperthermia in treating patients who have recurrent ovarian epithelial, fallopian tube, or peritoneal cancer.
