The Exon Junction Complex component EIF4A3 plays a splicing-linked oncogenic role in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, underscoring the urgent need for in-depth biological research. The phenomenon of alternative RNA splicing dysregulation is a common hallmark in cancer, including PDAC, presenting new avenues for understanding and developing diagnostic and therapeutic tools. Our research focuses on EIF4A3, a core component of the Exon Junction Complex intimately linked to RNA splicing, and its role in PDAC.

Efficacy of systemic Chemotherapy on high-risk stage II and III Mucnious colon cancer. CHEMUCCA study part I.

Background: Locally advanced colon cancer is a high-risk condition for tumour recurrence with poor survival. The current treatment is surgery followed by adjuvant chemotherapy based on fluoropyrimidines and oxaliplatin. This approach has improved the oncological outcomes on this population, however the mucinous condition has not been studied in depth and although the evidence is weak, it is thought to have a worse response to systemic chemotherapy.

Breaking the Mucin Barrier: A New Affinity Chromatography-Mass Spectrometry Approach to Unveil Potential Cell Markers and Pathways Altered in Pseudomyxoma Peritonei.

Background: Pseudomyxoma peritonei (PMP) is a rare peritoneal mucinous carcinomatosis with largely unknown underlying molecular mechanisms. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy is the only therapeutic option; however, despite its use, recurrence with a fatal outcome is common. The lack of molecular characterisation of PMP and other mucinous tumours is mainly due to the physicochemical properties of mucin.

Altered CELF4 splicing factor enhances pancreatic neuroendocrine tumors aggressiveness influencing mTOR and everolimus response.

Pancreatic neuroendocrine tumors (PanNETs) comprise a heterogeneous group of tumors with growing incidence. Recent molecular analyses provided a precise picture of their genomic and epigenomic landscape. Splicing dysregulation is increasingly regarded as a novel cancer hallmark influencing key tumor features.

Antitumor effect of a small-molecule inhibitor of KRAS in xenograft models of mucinous appendicular neoplasms.

Pseudomyxoma peritonei (PMP) is a rare disease characterized by a massive accumulation of mucus in the peritoneal cavity. The only effective treatment is aggressive surgery, aimed at removing all visible tumors. However, a high percentage of patients relapse, with subsequent progression and death.

Normothermic Regional Perfusion in Controlled Donation After Circulatory Determination of Death Simultaneous Pancreas - Kidney Transplantation.

Background: Simultaneous pancreas-kidney transplantation is the optimal treatment for patients with type 1 diabetes and renal failure. The use of pancreas grafts from donation after circulatory death (DCD), using normothermic regional perfusion (NRP), is still marginal worldwide, mainly due to possible additional risks of graft dysfunction and complications compared with grafts from donors after brain death.

Methods: Case series of patients who underwent simultaneous pancreas-kidney transplantation after DCD-NRP between January 2018 and September 2022.

Laparoscopic versus open approach for interval cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in advanced epithelial ovarian cancer: a matched comparative study.

Background: The use of the laparoscopic approach for the treatment of carcinomatosis from epithelial ovarian cancer (EOC) is controversial. The aim of this study was to compare the short-term outcomes of both laparoscopic and open approach for interval CRS+HIPEC in a matched cohort of patients with advanced EOC.

Methods: A retrospective analysis of a prospectively maintained database including 254 patients treated with interval CRS-HIPEC between January 2016 and December 2021 was performed.

Neoadjuvant Chemotherapy plus Interval Cytoreductive Surgery with or without Hyperthermic Intraperitoneal Chemotherapy (NIHIPEC) in the Treatment of Advanced Ovarian Cancer: A Multicentric Propensity Score Study.

Introduction: Epithelial ovarian cancer (EOC) is primarily confined to the peritoneal cavity. When primary complete surgery is not possible, neoadjuvant chemotherapy (NACT) is provided; however, the peritoneum-plasma barrier hinders the drug effect. The intraperitoneal administration of chemotherapy could eliminate residual microscopic peritoneal tumor cells and increase this effect by hyperthermia.

Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis from Urothelial Origin: a Case Report and Literature Review.

Introduction: Urothelial carcinomas (UC) are the fourth most common tumours. Approximately, 50% of patients with invasive bladder cancer relapse after radical cistectomy (RC). In this report, we present the case of peritoneal carcinomatosis from bladder UC treated with cytoreductive surgery plus the administration of hyperthermic intraperitoneal chemotherapy (CRS + HIPEC).

Recommendations for the optimal management of peritoneal metastases in patients with colorectal cancer: a TTD and GECOP-SEOQ expert consensus statement.

Peritoneal metastases (PM) occur when cancer cells spread inside the abdominal cavity and entail an advanced stage of colorectal cancer (CRC). Prognosis, which is poor, correlates highly with tumour burden, as measured by the peritoneal cancer index (PCI). Cytoreductive surgery (CRS) in specialized centres should be offered especially to patients with a low to moderate PCI when complete resection is expected.

Efficacy and Safety of Intraoperative Hyperthermic Intraperitoneal Chemotherapy for Locally Advanced Colon Cancer: A Phase 3 Randomized Clinical Trial.

Importance: Peritoneal metastasis in patients with locally advanced colon cancer (T4 stage) is estimated to recur at a rate of approximately 25% at 3 years from surgical resection and is associated with poor prognosis. There is controversy regarding the clinical benefit of prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) in these patients.

Objective: To assess the efficacy and safety of intraoperative HIPEC in patients with locally advanced colon cancer.

Peritoneal metastasis of advanced epithelial ovarian carcinoma treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: A retrospective international multicentric data analysis.

Learning curve for minimal invasive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) procedures.

Purpose: The benefits of the minimally invasive approach for performing cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (L-CRS + HIPEC) have been described previously, associating an early recovery with similar oncologic outcomes in patients with limited peritoneal carcinomatosis. Currently, no studies are focusing on the learning curve for this emerging procedure. This study aimed to evaluate the L-CRS + HIPEC learning curve and its knock-on effect on the perioperative outcomes.

Intraoperative oxygen tension and redox homeostasis in Pseudomyxoma peritonei: A short case series.

Introduction: Pseudomyxoma peritonei (PMP) is a rare malignant disease characterized by a massive multifocal accumulation of mucin within the peritoneal cavity. The current treatment option is based on complete cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy. However, the recurrence is frequent with subsequent progression and death.

Intraoperative metabolic changes associated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Background: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) causes considerable hemodynamic, respiratory, and metabolic changes during the perioperative period.

Objectives: To evaluate metabolic changes associated with this procedure. Understanding perioperative factors and their association with morbidity may improve the perioperative management of patients undergoing this treatment.

Short- and Long-Term Intestinal Complications After Combined Pancreas-Kidney Transplantation.

Background: Simultaneous pancreas-kidney (SPK) transplantation is the treatment of choice in patients with type 1 diabetes and end-stage renal disease, because it improves survival and quality of life. Currently, enteric exocrine drainage is the most commonly used method. Intestinal complications continue to be a major cause of posttransplant morbidity despite improvements in surgical technique.

The Role of Intraperitoneal Intraoperative Chemotherapy with Paclitaxel in the Surgical Treatment of Peritoneal Carcinomatosis from Ovarian Cancer-Hyperthermia versus Normothermia: A Randomized Controlled Trial.

Background: The treatment of ovarian carcinomatosis with cytoreductive surgery and HIPEC is still controversial. The effect and pharmacokinetics of the chemotherapeutics used (especially taxanes) are currently under consideration.

Methods: A phase II, simple blind and randomized controlled trial (NTC02739698) was performed.

Surgical treatment of vena cava leiomyosarcomas: Series of cases in a referral center and literature review.

Background: Primary tumors of the inferior vena cava are rare tumors of mesenchymal origin. They arise from the smooth muscles of the vena cava wall. Due to its low prevalence, there are few definitive data on its treatment and prognosis.

GECOP-MMC: phase IV randomized clinical trial to evaluate the efficacy of hyperthermic intraperitoneal chemotherapy (HIPEC) with mytomicin-C after complete surgical cytoreduction in patients with colon cancer peritoneal metastases.

Background: The French PRODIGE 7 trial, published on January 2021, has raised doubts about the specific survival benefit provided by HIPEC with oxaliplatin 460 mg/m (30 minutes) for the treatment of peritoneal metastases from colorectal cancer. However, several methodological flaws have been identified in PRODIGE 7, specially the HIPEC protocol or the choice of overall survival as the main endpoint, so its results have not been assumed as definitive, emphasizing the need for further research on HIPEC. It seems that the HIPEC protocol with high-dose mytomicin-C (35 mg/m) is the preferred regime to evaluate in future clinical studies.
