Active clinical trials for "Peritoneal Neoplasms"

This study determine the maximal tolerate dose

Patients with histological proven gastric cancer (including cancer of the esophagogastric junction (AEG)) and synchronous peritoneal carcinomatosis, who fulfill the inclusion and exclusion criteria, can be recruited in this study. There are two treatment groups (A and B). The chemotherapy applied intravenously is the same in both groups and is approved for the treatment of gastric cancer. Patients with negative or unknown HER-2 status will be administered Epirubicin, Oxaliplatin and Capecitabine (EOX). Patients with positive HER-2 status will be treated with Cisplatin, Capecitabine and Trastuzumab (CCT). The chemotherapy is followed by surgical cytoreduction in both groups. Patients randomized into group B will be treated with an intraperitoneal (in the abdominal cavity) chemoperfusion with Mitomycin C and Cisplatin . Patients in both groups receive 3 cycles of postoperative chemotherapy within 4-12 weeks after the surgical procedure and are followed up for 30 months. If progress of the tumor is detected the patient will no longer be treated according to the study therapy. Patients of group B may get a HIPEC intervention without surgical cytoreduction if contraindication to the drugs applied can be excluded.

Peritoneal carcinomatosis (PC) is the stage III of the FIGO ovarian cancer staging. It corresponds to an advanced stage with a relative 5 year survival rate of 52%. The multimodal treatment approach combines neoadjuvant chemotherapy, cytoreductive surgery of macroscopic lesions, and hyperthermic intraperitoneal chemotherapy (HIPEC). It has significantly improved survival rate in patients with ovarian PC and decreased recurrence and mortality rate by 21%. The efficacy of HIPEC is based on chemotherapy potentiated by the hyperthermia (43°). However, the cellular mechanisms involved are not fully understood, but they include cell death pathways and heat shock proteins (Hsp70 and Hsp90). RICCI et al. showed, based on pre-clinical models, that the efficacy of HIPEC was partly due to the overexpression and exposure of HSP90 on the cell surface leaded to an anti-cancer immune response. The aims of this study are to validate these findings in tissue samples of patients with ovarian PC. We will constitute a bank of isolated tumor samples before and after HIPEC and measure postoperative HSP90 serum levels in order to establish if they are predictive of a response. HSPs expression on the cancer cell surface will be determined by flow cytometry. Forty-four patients will be included. Elucidating the underlying mechanisms of HIPEC will broaden therapeutic possibilities including the use of new immunotherapy. The multimodal approach could improve the efficacy of HIPEC with a minimal systemic toxicity.

Intra Peritoneal Chemo Hyperthermia (IPCH) is a recently validated option for the treatment of peritoneal carcinomatosis from colorectal or ovarian origin. This therapeutic program demonstrated a significant improvement of the late stages (i.e. carcinomatosis) of the disease. From a clinical point of view, within the first 24 hours after IPCH, patients undergo a systemic inflammatory response syndrome, and therefore require to be monitored in an intensive care unit. From a metabolic perspective, preliminary data have been shown a significant "anaerobic style" disturbance of energetic metabolism, suggesting a deep cellular energetic deficit throughout IPCH process. Putative contradictory effects of IPCH, like the increase of chemotherapy-related cellular toxicity due to heat and on the other hand the initiation of a stress protein response (heat shock response) which helps to reduce the cell injuries, leads to conduct a research project on the underlying mechanisms: consequences, in terms of patient's care and follow-up, are of high relevance. The primary goal is a multimodal assessment of the IPCH-related cell modifications: signaling pathways, apoptosis and antitumoral immune response. The assessment criteria include Heat shock protein expression (blood/cell ratio) compared to baseline values, apoptosis and immune response before/after IPCH. The scheduled sample size is 30 patients having an IPCH and 30 patients contraindicated per surgery.

This clinical trial is studying how well granisetron, aprepitant, and dexamethasone work in preventing nausea and vomiting in patients receiving chemotherapy for stage II, stage III, or stage IV ovarian cancer. Granisetron patch, aprepitant and dexamethasone may help lessen or prevent nausea and vomiting in patients receiving chemotherapy for stage II, stage III, or stage IV ovarian cancer.

The treatment of advanced ovarian cancer is based on the combination of chemotherapy based on platinum salt and surgery whose quality is the major prognostic factor. A meta-analysis of retrospective series had shown that for every 10% increase in the complete cytoreduction rates were increased by 5.5% overall survival time (Markman et al, 2001). Currently, it is recognized that the best chance of survival conferred to patients whose initial surgical residue is zero (Harter et al, 2009). However, even if macroscopically complete surgery and whatever the type of systemic chemotherapy, peritoneal recurrence remains high for more than 75%. To reducing it of recurrence, a therapeutic approach is to administer chemotherapy intraperitoneally. The intraperitoneal chemotherapy consists to administer the drug directly into the peritoneal cavity. Alberts et al, 1996 and Armstrong et al, 2006 compared the efficacy in terms of survival of an intraperitoneal chemotherapy according to this method with a conventional systemic chemotherapy. Alberts reported a significant improvement in the median overall survival. Armstrong shows in addition a decreased risk of recurrence. It must be remembered that: The establishment of an intra-abdominal catheter does not always ensure complete flow of drugs into the peritoneal cavity (major postoperative adhesions). There may be problems of catheters becoming blocked and requiring local treatment; these problems can cause abdominal pain whose care is difficult. Thus almost half of patients fail to get all six courses of intraperitoneal chemotherapy. Thus, the investigators propose to estimate the flow of intraperitoneal chemotherapy with IP peritoneal scintigraphy, using a radiotracer (nanocis®). The investigators hypothesize that the movement of colloids in peritoneal cavity is similar to the circulation of chemotherapy within the peritoneal cavity (From Forni et al, 1993, Varia et al, 2003, Young et al, 2003, Dawson et al, 2011). The accumulation of radiotracer will be more correlated with abdominal pain sites described by the patient as well as peritoneal recurrence sites found during monitoring.

Peritoneal carcinomatosis (PC) results from the metastasis of a primary cancer of the peritoneum (e.g., appendiceal, ovarian, uterine, colorectal, and gastric cancers) that then disseminates throughout the abdominal cavity. Historically progression to PC was considered terminal and resulted in survival times on the scale of a few months with palliative care being the best option for patients. More recently, cytoreductive surgery (CS) has emerged as a means to prolong and improve patient lives with a median increase in survival of up to ~5 years. It has been reported that for every 10% increase in cytoreduction there is a 5.5% increase in median survival time. In addition to surgical tumor debulking within the peritoneal space, it has also been shown that coupling surgical intervention with hyperthermic intraperitoneal chemotherapy (HIPEC) can have an even greater impact on patient outcomes. Pegsitacianine, a micellar fluorescence agent, exploits the ubiquitous pH differences observed between cancerous and normal tissues. This in turn, provides a highly sensitive and specific fluorescence response after localizing within the tumor microenvironment, thus allowing the detection of primary tumors, their margins, metastatic disease, and tumor-containing lymph nodes.

This phase I trial investigates the side effects and best dose of abexinostat and palbociclib when given together with fulvestrant in treating patients with breast or gynecologic cancer. Abexinostat may prevent tumor cells from growing and multiplying and may kill tumor cells. Palbociclib may prevent or slow the growth of tumor cells when used with other anti-hormonal therapy. Estrogen can cause the growth of breast and gynecologic tumor cells. Fulvestrant may help fight breast or gynecologic cancer by blocking the use of estrogen by the tumor cells. Giving abexinostat, palbociclib, and fulvestrant may work better in treating patients with breast or gynecologic cancer.

This is a single-arm open-label Phase 2 study in patients with peritoneal carcinomatosis of ovarian origin that are not eligible for curative treatments. Patients will receive 5 weekly IV infusions of JX-594 until radiographically determined progressive disease. Patients will be allotted in a 1:1 ratio to undergo a laparoscopy and tumor biopsy 10 days after dose 1 or 10 days after Dose 5. Patients will be monitored on study until evidence of progression or death or for 12 months post treatment.

The purpose of this study is to determine if NIF fluorescent imaging is an effective approach to detect the gross ovarian tumoral tissues and peritoneal implants in Ovarian cancer patients.
