Tumour microenvironment characterisation to stratify patients for hyperthermic intraperitoneal chemotherapy in high-grade serous ovarian cancer (OVHIPEC-1).

Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) improves survival in patients with Stage III ovarian cancer following interval cytoreductive surgery (CRS). Optimising patient selection is essential to maximise treatment efficacy and avoid overtreatment. This study aimed to identify biomarkers that predict HIPEC benefit by analysing gene signatures and cellular composition of tumours from participants in the OVHIPEC-1 trial.

Lessons learned from postmarketing withdrawals of expedited approvals for oncology drug indications.

In the past decade, there have been a record number of oncology therapy approvals by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Besides the EMA's conditional marketing authorisation programme and the FDA's Accelerated Approval Program, we observe a tendency towards fast approval for exploratory studies with non-randomised, uncontrolled designs and surrogate endpoints. This issue raises concerns about the robustness and effectiveness of accepted treatments, leaving patients and health-care professionals in a state of uncertainty.

Differences in time to patient access to innovative cancer medicines in six European countries.

Patients across Europe face inequity regarding access to anticancer medicines. While access is typically evaluated through reimbursement status or sales data, patients can receive first access through early access programs (EAPs) or off-label use. This study aims to assess the time to patient access at the hospital level, considering different indications and countries.

Targeted combination therapies in oncology: Challenging regulatory frameworks designed for monotherapies in Europe.

The pharmaceutical value chain, including clinical trials, pricing, access, and reimbursement, is designed for classical monotherapies. Although there has been a paradigm shift that increases the relevance of targeted combination therapies (TCTs), regulation and common practice have been slow to adapt. We explored access to 23 TCTs for advanced melanoma and lung cancer as reported by 19 specialists from 17 leading cancer institutions in nine European countries.

Effect of HIPEC according to HRD/BRCAwt genomic profile in stage III ovarian cancer: Results from the phase III OVHIPEC trial.

The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin to interval cytoreductive surgery improves recurrence-free (RFS) and overall survival (OS) in patients with stage III ovarian cancer. Homologous recombination deficient (HRD) ovarian tumors are usually more platinum sensitive. Since hyperthermia impairs BRCA1/2 protein function, we hypothesized that HRD tumors respond best to treatment with HIPEC.

Cell-Free DNA at Diagnosis for Stage IV Non-Small Cell Lung Cancer: Costs, Time to Diagnosis and Clinical Relevance.

Tissue biopsies can be burdensome and are only effective in 10-30% of patients with metastasized non-small-cell lung cancer (mNSCLC). Next-generation sequencing (NGS) on cell-free DNA (cfDNA) might be an attractive alternative. We evaluated the costs, throughput time, and diagnostic yield of two diagnostic scenarios with tissue and cfDNA for mNSCLC patients, compared to diagnostics based on tissue biopsy alone.

Central radiology assessment of the randomized phase III open-label OVHIPEC-1 trial in ovarian cancer.

Introduction: Hyperthermic intraperitoneal chemotherapy (HIPEC) improved investigator-assessed recurrence-free survival and overall survival in patients with stage III ovarian cancer in the phase III OVHIPEC-1 trial. We analyzed whether an open-label design affected the results of the trial by central blinded assessment of recurrence-free survival, and tested whether HIPEC specifically targets the peritoneal surface by analyzing the site of disease recurrence.

Methods: OVHIPEC-1 was an open-label, multicenter, phase III trial that randomized 245 patients after three cycles of neoadjuvant chemotherapy to interval cytoreduction with or without HIPEC using cisplatin (100 mg/m).

No influence of sarcopenia on survival of ovarian cancer patients in a prospective validation study.

Objective: Decrease in skeletal muscle index (SMI) during neoadjuvant chemotherapy (NACT) has been associated with worse outcome in patients with advanced ovarian cancer. To validate these findings, we tested if a decrease in SMI was a prognostic factor for a homogenous cohort of patients who received NACT in the randomized phase 3 OVHIPEC-trial.

Methods: CT-scans were performed at baseline and after two cycles of neoadjuvant chemotherapy in stage III ovarian cancer patients.

Hyperthermic intraperitoneal chemotherapy for ovarian cancer: The heat is on.

Patients with advanced epithelial ovarian cancer have a high incidence of peritoneal disease recurrence despite maximal efforts to surgically remove all visible tumor plus intravenous chemotherapy. The administration of intraperitoneal chemotherapy that specifically targets the peritoneal surface has been investigated in previous trials, but questions about the design of these studies has prevented this treatment from being widely adopted in clinical practice. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a single intraoperative approach that also targets the peritoneal surface.

Cost Effectiveness of Interval Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy in Stage III Ovarian Cancer on the Basis of a Randomized Phase III Trial.

Purpose: In the randomized open-label phase III OVHIPEC trial, the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improved recurrence-free and overall survival in patients with stage III ovarian cancer. We studied the cost effectiveness of the addition of HIPEC to interval CRS in patients with ovarian cancer.

Patients And Methods: We constructed a Markov health-state transition model to measure costs and clinical outcomes.

Hyperthermic Intraperitoneal Chemotherapy in Ovarian Cancer.

Background: Treatment of newly diagnosed advanced-stage ovarian cancer typically involves cytoreductive surgery and systemic chemotherapy. We conducted a trial to investigate whether the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery would improve outcomes among patients who were receiving neoadjuvant chemotherapy for stage III epithelial ovarian cancer.

Methods: In a multicenter, open-label, phase 3 trial, we randomly assigned 245 patients who had at least stable disease after three cycles of carboplatin (area under the curve of 5 to 6 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area) to undergo interval cytoreductive surgery either with or without administration of HIPEC with cisplatin (100 mg per square meter).

Emphysematous cholecystitis due to Clostridium perfringens successfully treated by cholecystectomy.

Emphysematous Cholecystitis is life threatening if left untreated. It is associated with arteriosclerosis, embolic events, and diabetes mellitus. In this report, a patient was presented with an early diagnosis of Emphysematous Cholecystitis and was treated by cholecystectomy without complications.
