heated intraperitoneal chemotherapy

BACKGROUND/AIM: Emerging data suggest that addition of hyperthermic intraperitoneal chemotherapy (HIPEC) at the time of interval cytoreduction for patients with metastatic ovarian cancer is associated with a survival benefit. However, the implementation of this treatment is affected by concerns related to its potential morbidity. We present data from the first centre in the UK implementing HIPEC as part of treatment for patients with advanced ovarian cancer undergoing interval cytoreductive surgery...

BACKGROUND/AIM: Colorectal adenocarcinoma (CRAdenoCa) and appendiceal adenocarcinoma (AAdenoCa) are diseases of the same histopathological type that metastasise to the liver and peritoneum. In selected subgroups, peritonectomy and heated intraperitoneal chemotherapy (HIPEC) may be indicated as part of the multimodal treatment plan. However, literature comparing the survival outcomes and preoperative tumour activity and burden of CRAdenoCa and AAdenoCa peritonectomy patients without synchronous liver metastases (sLM) is scarce...

Peritoneal carcinosis has historically been considered as inoperable, although the technique of its resesection together with high dose intraperitoneal chemotherapy potentiated by heat has been described decades ago. It has not became a widely practiced routine except in specialized centers - the complex technique, weakly standardized but resource demanding chemotherapy, lacking financial background and the many times questionable clinical benefit at a cost of high surgical load might have been the key factors...

BACKGROUND: Heterogenous nomenclature describing appendiceal neoplasms has added to uncertainty around their appropriate treatment. Although a recent consensus has established the term low-grade appendiceal neoplasm (LAMN), we hypothesize that significant variation remains in the treatment of LAMNs. METHODS: We retrospectively reviewed our prospectively maintained appendiceal registry, identifying patients with LAMNs from 2009 to 2019. We assessed variability in treatment, including whether patients underwent colectomy, spread of disease at presentation, and long-term outcomes...

Hyperthermia combined with intraperitoneal (IP) drug delivery is increasingly used in the treatment of peritoneal metastases (PM). Hyperthermia enhances tumor perfusion and increases drug penetration after IP delivery. The peritoneum is increasingly recognized as an immune-privileged organ with its own distinct immune microenvironment. Here, we review the immune landscape of the healthy peritoneal cavity and immune contexture of peritoneal metastases. Next, we review the potential benefits and unwanted tumor-promoting effects of hyperthermia and the associated heat shock response on the tumor immune microenvironment...

OBJECTIVES: Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is associated with significant postoperative complications. Early detection of at-risk patients may lead to improved outcomes. The role of C-reactive protein (CRP) in predicting postoperative complications has only been recently investigated. METHODS: Postoperative complications were categorized according to Clavien-Dindo classification and further divided into minor (Grade <3) and major complications (Grade ≥3A)...

PURPOSE: Cytoreductive surgery (CRS) is often combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of peritoneal tumour deposits. Considering CRS, the evidence relating the large incisions, local chemotherapy and abdominal wall trauma to incisional hernias (IH) has not been synthesized. This systematic review and meta-analysis was conducted to examine the proportion of IH present in patients post CRS and the effect HIPEC had on these rates. METHODS: PubMed, EMBASE, and Cochrane Central Registry of Trials were searched up to June 2023 to examine studies relating IH and CRS plus or minus HIPEC...

After surgery for ovarian cancer or colorectal cancer, residual tumors are left around. A practical way to treat residual tumors is to destroy them with heat by injecting high-temperature drugs into the abdominal cavity. The injected medicinal substances are induced to flow out of the abdominal cavity; then, the spilled drug flows back into the abdominal cavity through feedback. During this process, the heat starts to decrease; thus, the treatment performance reduces. To overcome this problem, this study compares and assesses the temperature needed to maintain the heat for treatment and transmits a command signal to the heat exchanger through a look-up table (LUT)...

Endometrial cancer and uterine sarcoma represent the two major types of uterine cancer. In advanced stages, both cancer entities are challenging to treat and correlate with a meagre survival and prognosis. Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a form of localized chemotherapy that is heated to improve the chemotherapeutic effect on peritoneal metastases. The aim of the current review is to study the role of HIPEC in the treatment of uterine cancer. A literature review was conducted using the MEDLINE and LIVIVO databases with a view to identifying relevant studies...

INTRODUCTION: Hyperthermic IntraPEritoneal Chemotherapy (HIPEC) aims to treat microscopic disease left after CytoReductive Surgery (CRS). Thermal enhancement depends on the temperatures achieved. Since the location of microscopic disease is unknown, a homogeneous treatment is required to completely eradicate the disease while limiting side effects. To ensure homogeneous delivery, treatment planning software has been developed. This study compares simulation results with clinical data and evaluates the impact of nine treatment strategies on thermal and drug distributions...

BACKGROUND: Pseudomyxoma Peritonei (PMP) is a severe neoplastic clinical syndrome characterised by secretion of mucin from tumors often originating in the appendix. The standard treatment includes cytoreductive surgery (CRS) combined with heated intraperitoneal chemotherapy (HIPEC). A new perspective in PMP treatment aims at the mucins themselves as a therapeutic target. CASE PRESENTATION: Here we report the first case of PMP with peritoneal dissemination of mucinous implants caused by low-grade appendiceal mucinous neoplasm (LAMN) in a 58-year-old white male exclusively treated by appendectomy and oral administration of bromelain and acetylcysteine in the context of a medical self-experimentation (by co-author T...

Clinical hyperthermic intraperitoneal chemotherapy (HIPEC) is regarded as a potential treatment that can prolong survival of patients with peritoneal metastases after cytoreductive surgery. However, treated tumor cells are prone to becoming heat resistant to HIPEC therapy through high expression of heat shock proteins (HSPs). Here, a carrier-free bifunctional nanoinhibitor was developed for HIPEC therapy in the management of peritoneal metastases. Self-assembly of the nanoinhibitor was formed by mixing Mn ion and epigallocatechin gallate (EGCG) in a controllable manner...

INTRODUCTION AND IMPORTANCE: Benign multicystic peritoneal mesothelioma is rare, with around 200 cases reported in the literature. We report the case of a patient operated on for the diagnosis of cystic lymphangioma but the pathology examination retained the diagnosis of benign cystic peritoneal mesothelioma. CASE PRESENTATION: A 47-year-old patient, who consulted for abdominal distension evolving for a year. Examination revealed a 30-centimeter abdominal mass. The CT scan showed an intraperitoneal cystic mass measuring 24 × 13 × 32 cm...

INTRODUCTION: Peritoneal mesothelioma (PM) is a rare malignancy originating from the peritoneal lining. Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is the standard-of-care for patients with isolated PM. Due to a paucity of prospective data there are several different HIPEC protocols. The aims of this study are to describe the CRS and HIPEC protocols for PM and patient outcomes across Canada. METHODS: A multicenter retrospective study was performed on patients diagnosed and treated for PM with CRS and HIPEC in four major peritoneal disease centers in Canada between 2000 and 2021...

BACKGROUND AND AIMS: Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is an established treatment in selected patients with peritoneal metastases, delivered in the UK in specialist centres. HIPEC can be administered via the open coliseum technique as first described by Sugarbaker (O-HIPEC) or using a closed technique (C-HIPEC). Data comparing the safety and outcomes of these different approaches is limited. This study aims to compare morbidity and mortality rates of O-HIPEC and C-HIPEC following CRS for peritoneal metastases from colorectal cancer and appendiceal tumours...

Peritoneal carcinomatosis (PC) refers to metastatic spread of tumor into the peritoneal cavity. Earlier, PC was thought to be associated with grave clinical outcome. However, various advances in treatment options including cytoreductive surgery and heated intraperitoneal chemotherapy or early post-operative chemotherapy can prolong survival of patients with peritoneal carcinomatosis. These treatment options are associated with high morbidity and mortality. The purpose of this article is to acquaint the radiologist about various appearances of peritoneal carcinomatosis in order to help clinicians in selecting candidates for surgery and avoid unnecessary potentially debilitating surgeries in patients with unresectable PC...

OBJECTIVES: Appendiceal cancer is a rare malignancy, occurring in roughly 1.2 per 100,000 per year. Low grade appendiceal neoplasams (LAMN) in particular can lead to pseudomyxoma peritonei (PMP), and respond poorly to systemic chemotherapy. Standard treatment includes cytoreduction surgery (CRS) with addition of heated intraoperative peritoneal chemotherapy (HIPEC). Several centres include early postoperative intraperitoneal chemotherapy (EPIC) however; the literature is mixed on the benefits...

BACKGROUND Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm with a poor prognosis. Bidirectional intraoperative chemotherapy (BDIC) using concurrent intraperitoneal and intravenous chemotherapy in combination with cytoreductive surgery (CRS) is an emerging treatment option for selected cases of MPM. It is a locoregional treatment that involves intraoperative chemoperfusion of heated chemotherapy. The administration of systemic along with intraperitoneal chemotherapy allows for a bidirectional chemotherapy gradient in peritoneal tumor cells...
