Abstract
BACKGROUND The aim of hyperthermic intraperitoneal chemotherapy (HIPEC) is to eradicate microscopic residual tumor after radical surgical tumor excision in patients with peritoneal carcinomatosis. The common use of antineoplastic agents such as mitomycin C, doxorubicin, or oxaliplatin with hyperthermia fails to eradicate tumors in a significant subset of patients, and alternative approaches to target chemoresistant cells are needed. The induction of reactive oxygen species (ROS) by inhibiting the critical detoxification enzyme superoxide dismutase (SOD) during hyperthermia is an appealing approach to induce death of residual cancer cells. METHODS Human and murine colon cancer cell lines were subjected to mild hyperthermia (40-42°C), and treated with chemotherapy, similar to clinical protocols. ROS were induced by the SOD inhibitor diethyldithiocarbamate (DDC), a metabolite of the drug disulfiram. In mice, peritoneal carcinomatosis use C57Bl/6 was induced in C57Bl/6 by intraperitoneal injection of syngenic tumor cells (MC38). RESULTS Hyperthermia alone failed to kill cells but induced intracellular ROS and activated protective mechanisms. Chemotherapy conferred inconsistent cytotoxicity depending on the cell line and dose. In contrast, induction of ROS by DDC consistently activated apoptotic pathways, with increased cell death in combination with mild hyperthermia. In vivo, combined treatment with DDC and hyperthermia significantly delayed tumor progression in tumor-bearing mice. In addition, hyperthermic combined treatment with chemotherapy and DDC significantly improved animal survival compared with chemotherapy alone. CONCLUSIONS Addition of DDC improves the efficacy of existing HIPEC protocols in a safe way and may open the door to a more effective, multimodal HIPEC.

Abstract
<b><i>Background: </i></b>Peritoneal metastasis arising from colorectal cancer, appendiceal cancer, gastric cancer and gynecologic malignancies, or primary peritoneal surface malignancies such as peritoneal mesothelioma and primary peritoneal adenocarcinoma may be efficiently treated by cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in selected patients. <b><i>Method: </i></b>CRS is based on the technique of parietal and visceral peritonectomy and consists of multiple surgical procedures. HIPEC combines high local doses of cytostatics with the additional cytotoxic effects of hyperthermia. <b><i>Results: </i></b>The goal of CRS is to achieve a complete macroscopic cytoreduction (CC-0/1) as a precondition for consecutive HIPEC that should destroy residual tumor cells within the abdominal cavity. <b><i>Conclusion: </i></b>CRS and HIPEC can be performed with acceptable morbidity and low mortality in specialized centers. However, due to long learning curves, consistent surgical training is strongly recommended.

Abstract
The pharmacokinetics of pegylated liposomal doxorubicin (PLD) were investigated in 17 women undergoing intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) for advanced ovarian cancer and peritoneal carcinomatosis. HIPEC was performed immediately after completing debulking surgery, which included a number of peritonectomy procedures. PLD was injected and allowed to equilibrate in peritoneal cavity filled with 4 liters of physiological solution and stabilized at 42°C; next, the outflow line was opened and perfusion proceeded for 1 h. PLD was stable in peritoneal perfusate and plasma. During HIPEC, PLD peritoneal perfusate/plasma gradients averaged ∼600 or ≥1000 for peak concentration or area under the curve. After HIPEC, PLD plasma levels remained stable or decreased. Biopsy samples of residual normal peritoneum or ovarian carcinomatosis were collected at the end of HIPEC and were shown to contain free doxorubicin. Correlating PLD decrements in peritoneal perfusate with plasma exposure to PLD or peritoneal deposition of free doxorubicin showed that the former occurred during preperfusional equilibration of PLD in peritoneal cavity, whereas the latter occurred during 1 h of perfusion. Plasma exposure to PLD correlated negatively with the number of peritonectomy procedures performed during surgery, whereas peritoneal deposition of free doxorubicin correlated positively. Taken together, these results show that PLD administered by intraoperative HIPEC undergoes limited systemic diffusion and releases active free doxorubicin in peritoneum exposed to ovarian carcinomatosis. PLD pharmacokinetics seem to be influenced by peritonectomy procedures.

Abstract
Peritoneal carcinomatosis arising from gastric cancer is mostly associated with poor prognosis. Despite the improvement of survival with modern polychemotherapy, the results are still unsatisfactory. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy might provide an additional therapeutic option for highly selected patients with gastric cancer and peritoneal metastasis leading to improved prognosis. Considering the increased rate of perioperative morbidity and the crucial prognostic role of complete macroscopic cytoreduction, adequate preoperative diagnostics and patient selection are strongly recommended. Further prospective randomized trials are needed to determine the roles of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy as part of an interdisciplinary treatment concept.

Abstract
Significant toxicities from multiple cycles of chemotherapy often cause delays or early termination of treatment, leading to poor outcomes in ovarian cancer patients. Complementary modalities that potentiate the efficacy of traditional agents with fewer cycles and less toxicity are needed. Photodynamic therapy is a mechanistically-distinct modality that synergizes with chemo and biologic agents. A combination regimen with a clinically relevant chemotherapy cocktail (cisplatin + paclitaxel) and anti-EGFR targeted photoimmunotherapy (PIT) is evaluated in a murine model for ovarian carcinomatosis. Mice received either 1 or 2 chemotherapy cycles followed by PIT with a chlorine6-Erbitux photoimmunoconjugate and 25 J/cm2 light. PIT + 1 cycle of chemotherapy significantly reduced tumor burden, comparable to multiple chemotherapy cycles. Relative to 1 cycle of chemotherapy, the addition of PIT did not cause significant mouse weight loss, whereas 2 cycles of chemotherapy led to a significant reduction in weight. Irradiance-dependence on PIT efficacy was a function of the conjugation chemistry, providing an additional variable for optimization of PIT outcome.

Abstract
Peritoneal carcinomatosis from gastric cancer is considered a fatal disease with limited treatment options. Recent advances in the understanding of the disease process, systemic chemotherapy, and application of cytoreductive surgery and hyperthermic chemoperfusion have shown promising results in the management of this difficult disease. Novel therapies such as extensive intraperitoneal lavage and intraperitoneal targeted agents are being applied in the management of this disease. We review the current literature in this field and describe the rationale behind some of these advances.

Abstract
The current study characterizes the impact of docetaxel (DTX) distribution on efficacy following sustained intraperitoneal (IP) chemotherapy in murine models of ovarian cancer. A polymer-lipid biodegradable depot (PoLigel) was used to deliver DTX in a sustained manner over 21-days following IP administration. Distribution and efficacy studies were carried out in SCID mice bearing SKOV3 IP solid tumors or C57BL/6 mice with ID8 IP ascites fluid. In addition, a subcutaneous (SC) SKOV3 model was used to determine whether systemic drug levels that result from IP administration of the PoLigel influence antitumor efficacy. Immunostained IP and SC SKOV3 tumor sections were used to study cell death, intratumoral drug distribution and tumor penetration. Sustained concentrations of DTX were observed in plasma, tissue, tumor and ascites over the entire study period. Drug accumulation was several fold greater in tumors and ascites when compared to plasma levels. Sustained chemotherapy resulted in significant reduction in tumor burden and ascites volume. IP tumors showed greater cell death compared to the SC tumors as seen by higher TUNEL and caspase-3 expression. At the intratumoral level, DTX distributed more towards the core of IP tumors compared to the SC tumors. Tumor penetration of drug from nearest blood vessel was 1.5 fold greater in the IP tumors than the SC tumors. Overall, favorable drug distribution at the whole-body, peritoneal and intratumoral levels in combination with local and systemic sustained drug exposure contribute to the high efficacy observed. These results encourage the clinical use of IP sustained chemotherapy for ovarian cancer.

Abstract
BACKGROUND 15% to 20% of patients with metastatic colorectal cancer show isolated peritoneal carcinomatosis with significat clinical relevance. Their prognosis is poor, with a reported mean survival of less than one year. Moreover, there is a lack of knowledge regarding treatment optimally tailored to individual patients. METHODS To identify and characterize the current treatment options for this condition, we reviewed pertinent literature retrieved by a PubMed search on the terms "peritoneal carcinomatosis," "colorectal cancer," "treatment," "hyperthermic intraperitoneal chemotherapy," "cytoreductive surgery," and "humans." RESULTS Most patients with peritoneal carcinomatosis are treated with systemic chemotherapy in addition to best supportive care. Some undergo surgical or interventional treatment, such as ostomy or stent placement for intestinal obstruction. About one-third are candidates for multimodal treatment, consisting of surgical cytoreduction with intraoperative hyperthermic intraperitoneal chemotherapy. The main selection criteria are limited tumor mass (peritoneal cancer index <20), absence of organ metastases, feasibility of complete macroscopic cytoreduction (absence of disseminated small bowel disease), and approval of the interdisciplinary tumor board. Patients selected in this way have a 5-year survival rate of 30% to 50% after multimodal treatment. CONCLUSION The treatment of peritoneal carcinomatosis is usually considered to be purely palliative, in view of the extensive spread of the disease. However, for a subgroup of patients multimodal treatment can be provided with curative intent. The available survival data support the provision of multimodal strategies, including cytoprotective surgery, intraoperative intraperitoneal and systemic chemotherapy, for patients with peritoneal carcinomatosis in specialized centers. This type of treatment should be incorporated into treatment algorithms and guidelines.

Abstract
OBJECTIVES While intraperitoneal (IP) chemotherapy has shown significant survival benefits, the ability to successfully deliver IP chemotherapy has been limited. In GOG 172, surgically-placed IP catheters had a reported complication rate of 34%. In addition, IP catheters have to be placed surgically. We have developed a novel percutaneous placement technique for IP catheters in patients without ascites. METHODS This study was a retrospective analysis of all patients receiving percutaneously-placed IP catheters from 12/2008 to present. Catheters were placed using a two-step technique under conscious sedation. IP access was gained using ultrasound-guided peritoneal puncture over the right lobe of the liver. A 5 Fr catheter was placed into the peritoneal cavity and the abdomen insufflated with carbon dioxide (CO(2)). Access was gained in the RLQ once distention separated the bowel from the abdominal wall. A 14.5 Fr multi-side hole catheter was coiled in the pelvis, and a reservoir tunneled onto the lower anterior chest wall. For this analysis, abstracted data included patient demographics, indication for catheter placement, complications (procedural and with chemotherapy delivery), fluoroscopy time, and timing/indication of catheter removal. RESULTS Eleven patients received IP catheters. The mean age was 58 years, mean body mass index was 27.1, and mean number of days from surgical debulking was 38. There were two stage 2, and eight stage 3 patients. Two patients had fallopian tube, and nine patients had ovarian cancer. All patients had an optimal debulking procedure. Seven of 11 patients also obtained central intravenous access when the IP port was placed. Follow-up data were as follows: Average fluoroscopy time was 9 min. One patient (9%) had an intra-procedural complication but the catheter was successfully placed. Zero patients had catheter-related complications in the course of receiving chemotherapy. Five of the 11 patients (45%) completed the planned IP chemotherapy treatments, with three additional patients (27%) currently receiving therapy. The remaining three patients (27%) discontinued chemotherapy for reasons unrelated to IP catheter function: two due to chemotherapy side effects, and one with sepsis from a perforated diverticulum. CONCLUSIONS Thus far, our experience with percutaneous placement of IP catheters is associated with a low risk of catheter-related complications and high technical success rates. CO(2) insufflation may make peritoneal puncture easier and potentially safer. This procedure offers an alternative to surgical placement, even in patients without clinically significant ascites.

Abstract
The tumour microenvironment regulates tumour progression and the spread of cancer in the body. Targeting the stromal cells that surround cancer cells could, therefore, improve the effectiveness of existing cancer treatments. Here, we show that magnetic nanoparticle clusters encapsulated inside a liposome can, under the influence of an external magnet, target both the tumour and its microenvironment. We use the outstanding T2 contrast properties (r2=573-1,286 s(-1) mM(-1)) of these ferri-liposomes, which are ∼95 nm in diameter, to non-invasively monitor drug delivery in vivo. We also visualize the targeting of the tumour microenvironment by the drug-loaded ferri-liposomes and the uptake of a model probe by cells. Furthermore, we used the ferri-liposomes to deliver a cathepsin protease inhibitor to a mammary tumour and its microenvironment in a mouse, which substantially reduced the size of the tumour compared with systemic delivery of the same drug.

Abstract
Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown promise in treatment of ovarian carcinosis. Despite its efficiency for the treatment of peritoneal carcinosis from digestive tract neoplasia, it has failed to demonstrate significant benefit in ovarian cancers. It is therefore essential to understand the mechanism underlying resistance to HIPEC in ovarian cancers. Mesenchymal stem cells (MSC) play an important role in the development of ovarian cancer metastasis and resistance to treatments. A recent study suggests that MSCs may be cytotoxic for cancer cells upon heat shock. In contrast, we describe the protective role of MSC against hyperthermia. Using cytokine arrays we determined that the tumor associated MSC (TAMC) secrete pro-tumoral cytokines. We studied the effect of hyperthermia in co-culture setting of TAMC or BM-MCS associated with ovarian cancer cell lines (SKOV3 and CaOV3) with polyvariate flow cytometry. We demonstrate that hyperthermia does not challenge survival of TAMC or bone marrow derived MSC (BM-MSC). Both TAMC and BM-MSC displayed strong protective effect inducing thermotolerance in ovarian cancer cells (OCC). Transwell experiments demonstrated the role of secreted factors. We showed that CXCL12 was inducing thermotolerance and that inhibition of CXCL12/CXCR4 interaction restored cytotoxicity of hyperthermia in co-culture experiments. Contrary to the previous published study we demonstrated that TAMC and BM-MSC co-cultured with OCC induced thermotolerance in a CXCL12 dependant manner. Targeting the interaction between stromal and cancer cells through CXCL12 inhibition might restore hyperthermia sensitivity in ovarian cancers, and thus improve HIPEC efficiency.

Abstract
Peritoneal Malignant Disease (PMD) is the presence of tumoral tissue on the peritoneal surface from primary tumors or tumors from other locations (e.g. digestive or gynecologic). It is a regional disease with poor prognosis when treated with repeated "debulking" and traditional systemic chemotherapy. Cytoreduction plus hyperthermic intraperitoneal chemotherapy (HIPEC) is a combined multimodal regional procedure aimed at reducing the macroscopic tumoral mass as much as possible and treating with chemotherapy the microscopic disease that is out of the scope of the surgeon. This combined treatment may change the natural history of PMD, it is translated into a higher overall survival and cancer-free survival and it offers the option of cure in selected cases. The high-complexity procedure is also associated with complications and mortality, but in similar rates as other major oncologic procedures.
