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.

Article Synopsis
  • * A survey conducted from February 2021 to August 2022 among healthcare professionals in France highlighted a lack of adherence to the 2018 ESGO recommendations for LACC treatment, with notable differences in practices between university hospitals and other settings.
  • * Compliance rates were particularly low among gynecologic surgeons, with only 5.7% aligning with ESGO guidelines, which may directly affect patient outcomes; thus, there's a potential need for more structured care in specialized centers.

Purpose: Xevinapant is an orally available inhibitor of apoptosis proteins (IAP) inhibitor. Preclinical data suggest that IAP antagonism may synergize with immune checkpoint blockers by modulating the NFκB pathway in immune cells.

Patients And Methods: Adult patients with non-high microsatellite instability advanced/metastatic pancreatic ductal adenocarcinoma (PDAC) or colorectal cancer were enrolled in this phase Ib/II study and received pembrolizumab 200 mg every 3 weeks intravenously, and ascending doses of oral xevinapant (100, 150, and 200 mg daily for 14 days on/7 days off).

Tumor-associated macrophages (TAMs) are a critical determinant of resistance to PD-1/PD-L1 blockade. This phase 1 study (MEDIPLEX, NCT02777710) investigated the safety and efficacy of pexidartinib, a CSF-1R-directed tyrosine kinase inhibitor (TKI), and durvalumab (anti-PD-L1) in patients with advanced colorectal and pancreatic carcinoma with the aim to enhance responses to PD-L1 blockade by eliminating CSF-1-dependent suppressive TAM. Forty-seven patients were enrolled.

Article Synopsis
  • A significant portion (13%) of HER2-positive metastatic breast cancer patients treated with trastuzumab and pertuzumab experienced isolated Central Nervous System (CNS) progression, typically around 12 months after diagnosis.
  • Among the 120 patients analyzed, nearly two-thirds received CNS-targeted local therapy, and results showed no difference in progression-free survival between those who continued trastuzumab-pertuzumab and those who switched to another treatment.
  • Continuing trastuzumab-pertuzumab therapy after local treatment was linked to improved overall survival, indicating that more research and clinical trials are needed for effective treatment strategies in these cases.

Article Synopsis
  • The study analyzes the error introduced when using the Kaplan-Meier estimate for survival data that is not fully mature, focusing on how different maturity levels affect long-term life expectancy projections in economic evaluations.
  • It compared data from phase 3 trials reporting overall survival (OS) with 70% maturity to artificially truncated data sets representing lower maturities (30% and 50%) using various statistical methods.
  • Results indicated that as OS maturity increases, the accuracy of life expectancy estimates improves, emphasizing the importance of using mature data when developing economic models.

Article Synopsis
  • A specific type of metastatic triple-negative breast cancer (mTNBC) shows increased sensitivity to platinum-based chemotherapy due to homologous recombination deficiency (HRD), prompting a study to explore genetic alterations and their impact on treatment response.
  • In a study involving mTNBC patients, tumors were analyzed for mutations in 19 HRR genes, and patients were grouped based on their molecular status to evaluate responses to platinum therapy.
  • Results indicated that mutations in specific HRR genes and promoter methylation were linked to better disease control, suggesting that broader genetic evaluations could help identify more patients who might benefit from platinum treatment.

Article Synopsis
  • The study compares laparoscopic interval debulking surgery (IDS) and laparotomy outcomes in patients with stage III or IV serous ovarian cancer post-neoadjuvant chemotherapy.
  • Results showed no significant difference in overall survival (OS) and progression-free survival (PFS) between both surgical methods, although laparoscopy had fewer early postoperative complications and shorter hospital stays.
  • Laparoscopy is suggested as a safe alternative to laparotomy for selected patients with advanced ovarian cancer, achieving comparable survival outcomes with reduced morbidity.

Epithelial ovarian cancer (EOC) is the most lethal of all gynecological cancers. Despite excellent responses to standard treatment in approximately 70% of patients, most of them will relapse within 5 years of initial treatment and many of them will develop chemotherapy-resistant disease. It is then important to find other means of treatment for these patients such as immunotherapy or targeted therapy.

  • Chemotherapy and standard treatments like anti-HER2 and PD-1 antibodies show limited long-term effectiveness for patients with gastroesophageal cancers.
  • A study on 147 patients revealed that adenocarcinoma was the most common type, with significant genomic alterations found, including in genes like TP53 and ERBB2.
  • Genomic profiling can identify treatable alterations in many patients, suggesting that using matched therapies could enhance survival rates, particularly in those with stage IV disease.

Lessons Learned: The combination of the antivascular endothelial growth factor receptor 2 monoclonal antibody, ramucirumab, and the type II MET kinase inhibitor, merestinib, is tolerable. Preliminary efficacy data suggest that the combination may provide clinical benefit to patients with metastatic colorectal cancer (mCRC). Further development of this combination would likely necessitate the identification of subsets of patients with mCRC where the clinical benefit is of clinical relevance.

The transmission of an intact and stable genetic code at each cell division relies on different DNA repair systems. Germline mutations of some of these genes cause cancer predisposition, whereas somatic mutations are frequently found in various cancer types, generating genomic instability. As a consequence, cancer cell becomes more susceptible to additional DNA damage.
