Article Synopsis
  • - Ovarian cancer is a major cause of death among gynecological cancers, and platinum-based chemotherapy is the primary treatment method, along with maintenance strategies to extend chemotherapy intervals.
  • - Current maintenance treatments include bevacizumab and poly ADP-ribose polymerase inhibitors, but these can only be used once during the disease's progression, leaving a gap in treatment for patients experiencing relapses.
  • - A new international Phase II trial is exploring a combination of a therapeutic cancer vaccine (OSE2101) and anti-PD1 (pembrolizumab) as a maintenance therapy for patients with platinum-sensitive recurrences, regardless of prior treatments.

Background: Robust molecular subtyping of triple-negative breast cancer (TNBC) is a prerequisite for the success of precision medicine. Today, there is a clear consensus on three TNBC molecular subtypes: luminal androgen receptor (LAR), basal-like immune-activated (BLIA), and basal-like immune-suppressed (BLIS). However, the debate about the robustness of other subtypes is still open.

Background: Standard treatment for patients with newly diagnosed glioblastoma includes surgery, radiotherapy (RT), and temozolomide (TMZ) chemotherapy (TMZ/RT→TMZ). The proteasome has long been considered a promising therapeutic target because of its role as a central biological hub in tumor cells. Marizomib is a novel pan-proteasome inhibitor that crosses the blood-brain barrier.

Objectives: The modeled CA-125 elimination constant K (KELIM) is a pragmatic early marker of tumor chemosensitivity in ovarian cancer patients treated with neoadjuvant chemotherapy before interval surgery. The primary objective of this study was to assess the prognostic value of KELIM regarding the feasibility of complete surgery, and secondary objectives were to assess the prognostic value of KELIM for the risk of a platinum resistant relapse, progression free survival, and overall survival.

Methods: The study was based on a retrospective cohort of 284 patients treated for an advanced serous high grade ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) stages III-IV, with neoadjuvant chemotherapy, followed by interval surgery, in a comprehensive cancer center.

Recommendations for clinical practice Nice/Saint-Paul-de-Vence 2022-2023 : Management of advanced/relapsing endometrial cancer Since the first recommendations in 2020 concerning metastatic and/or relapsed endometrial cancer, new treatment options have shown a benefit on patients' life expectancy, justifying their update. In first line, the choice will be made between chemotherapy with carboplatin/paclitaxel or hormone therapy with progestin, depending on tumor characteristics (histological type, grade, expression of hormone receptors, rate of progression). In case of a dMMR tumors, the use of immunotherapy within the framework of a therapeutic trial is an option.

Article Synopsis
  • Chemotherapy is a common treatment for early breast cancer but can be toxic to all patients, leading to the exploration of alternatives like the Oncotype DX test, which assesses cancer gene expression to predict recurrence risk and chemotherapy benefits.
  • A study evaluated the cost-effectiveness of Oncotype DX compared to standard care using a model that analyzed both short-term treatment decisions and long-term outcomes.
  • Results showed that Oncotype DX reduced chemotherapy usage by over 55%, increased quality-adjusted life-years by 0.337, and saved €3,412 per patient, making it a more effective and cheaper option that could enhance patient care and reduce health system costs.

The poor outcomes associated with mammary carcinomas (MCs) in dogs and cats in terms of locoregional recurrence, distant metastasis and survival, highlight the need for better management of mammary cancers in small animals. By contrast, the outcomes of women with breast cancer (BC) have dramatically improved during the last 10 years, notably thanks to new therapeutic strategies. The aim of this article was to imagine what could be the future of therapy for dogs and cats with MCs if it became inspired from current practices in human BC.
