Locally advanced and metastatic endometrial cancer: Current and emerging therapies.

Until recently, patients diagnosed with locally advanced and metastatic endometrial cancer faced significant challenges in their treatment due to limited options and poor prognostic outcomes. The sequencing of tumors has been a major advancement in its management. It has led to The Cancer Genome Atlas classification currently used in clinical practice and the initiation of several clinical trials for innovative treatments targeting principally signaling pathways, immune checkpoints, DNA integrity, growth factors, hormonal signaling, and metabolism. Numerous clinical trials are investigating a combinatorial approach of these targeted therapies to counter tumoral resistance, cellular compensatory mechanisms, and tumor polyclonality. This review provides a comprehensive overview of historical, current, and promising therapies in advanced and metastatic endometrial cancer. It particularly highlights clinical research on targeted and hormonal therapies, but also immunotherapy, reflecting the evolving landscape of treatment modalities for this disease.

Diagnostic Performance of Immunohistochemistry Compared to Molecular Techniques for Microsatellite Instability and p53 Mutation Detection in Endometrial Cancer.

Molecular algorithms may estimate the risk of recurrence and death for patients with endometrial cancer (EC) and may impact treatment decisions. To detect microsatellite instabilities (MSI) and p53 mutations, immunohistochemistry (IHC) and molecular techniques are used. To select the most appropriate method, and to have an accurate interpretation of their results, knowledge of the performance characteristics of these respective methods is essential. The objective of this study was to assess the diagnostic performance of IHC versus molecular techniques (gold standard). One hundred and thirty-two unselected EC patients were enrolled in this study. Agreement between the two diagnostic methods was assessed using Cohen's kappa coefficient. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) of the IHC were calculated. For MSI status, the sensitivity, specificity, PPV and NPV were 89.3%, 87.3%, 78.1% and 94.1%, respectively. Cohen's kappa coefficient was 0.74. For p53 status, the sensitivity, specificity, PPV, and NPV were 92.3%, 77.1%, 60.0% and 96.4%, respectively. Cohen's kappa coefficient was 0.59. For MSI status, IHC presented a substantial agreement with the polymerase chain reaction (PCR) approach. For the p53 status, the moderate agreement observed between IHC and next generation sequencing (NGS) methods implies that they cannot be used interchangeably.

Oncological patients' reactions to COVID-19 pandemic: A single institution prospective study.

BACKGROUND: The spread of the COVID-19 pandemic has led to a rapid reorganization in all human and hospital activities, with impact on cancer patients. AIM: An analysis of cancer patients fears, and awareness of COVID-19 has been done in this study. METHODS AND RESULTS: We analyzed cancer patients' reactions to the pandemic and their perception of oncological care reorganization, through a 12-item survey, proposed at the peak of pandemic and 3 months later. Overall, 237 patients were included in the study. During the peak of pandemic 34.6% of patients were more worried about COVID-19 than cancer versus 26.4% in the post-acute phase (p = .013). Although 49.8% of patients in the acute phase and 42.3% in the post-acute phase considered their risk of death if infected ≥50%, and more than 70% of patients thought to be at higher risk of complications, the majority of them did not consider the possibility to stop or delay their treatment. Patients were more interested in following news about COVID-19 than cancer and they complied with all preventive measures in more than 90% of the cases. CONCLUSIONS: Although cancer patients worried about COVID-19 and evaluated the risk of complication or death due to COVID-19 as extremely high, they were still asking for the best oncological treatment.

Cutaneous Breast Cancer Metastases Successfully Treated Using an Oxygen Flow Assisted Topical Administration of Methotrexate (OFAMTX).

INTRODUCTION: Cutaneous metastases of breast cancer remain a therapeutic challenge. Oxygen flow-assisted topical administration of methotrexate 5% (OFAMTX, 5% methotrexate in a carrier solution) has recently been proven to be an efficacious alternative treatment for extramammary Paget's disease, which is considered to be an in situ mammary adenocarcinoma of the epidermis. CASE REPORT: A 51-year-old patient with triple negative breast cancer presenting with biopsy-proven skin metastases on the chest agreed to a treatment with OFAMTX5%. The treatment duration was 2 weeks and consisted of twice-weekly sessions with OFAMTX5% applied to an area of skin of approximately 40 cm2. Skin biopsies were performed before and 2 months after procedure. The tolerance to the treatment was excellent, and no pain sensations were experienced. Two months post-procedure the treated area presented a post-inflammatory hyperpigmentation. No residual metastatic lesions were detectable on the control skin biopsy. Six months post-procedure the patient is still in clinical remission. DISCUSSION: OFAMTX5% represents an alternative skin-directed, painless, patient-friendly and efficacious adjuvant treatment for superficial metastatic lesions of breast cancer. Larger series are required to evaluate the potential of OFAMTX5% for the treatment of superficial metastatic lesions of breast cancer.
