Impact of the time interval between primary or interval surgery and adjuvant chemotherapy in ovarian cancer patients

IntroductionPrimary debulking surgery (PDS), interval debulking surgery (IDS), and platinum-based chemotherapy are the current standard treatments for advanced ovarian cancer (OC). The time to initiation of adjuvant chemotherapy (TTC) could influence patient outcomes.MethodsWe conducted a multicenter retrospective cohort study of advanced (International Federation of Gynecology and Obstetrics (FIGO) stage III or IV) OC treated between 2014 and 2018 to assess progression-free survival (PFS) and overall survival (OS) in relation to TTC. All patients underwent a germline multigene panel for BRCA1/2 evaluation.ResultsAmong the 83 patients who underwent PDS, a TTC ≥ 60 days was associated with a shorter PFS (hazard ratio (HR) 2.02, 95% confidence interval (CI) 1.04–3.93, p = 0.038), although this association lost statistical significance when adjusting for residual disease (HR 1.52, 95% CI 0.75–3.06, p = 0.244, for TTC and HR 2.73, 95% CI 1.50–4.96, p = 0.001, for residual disease). Among 52 IDS patients, we found no evidence of an association between TTC and clinical outcomes. Ascites, type of chemotherapy, or germline BRCA1/2 mutational status did not influence TTC and were not associated with clinical outcomes in PDS or IDS patients.DiscussionIn conclusion, longer TTC seems to negatively affect prognosis in patients undergoing PDS, especially those with residual disease

Effectiveness and safety of therapy with vitamin K antagonist in Italian patients aged 80 years or older: a multicentre retrospective study comparing Zeus algorithm with PARMA algorithm or manual therapy.

Background: Oral anticoagulant therapy (OAT) has constantly increased in the prevention of thromboembolism, above all in patients 80 years of age or older. The aim of this multicentre study was to evaluate efficacy and safety of vitamin K antagonist (VKA) in elderly patients managed with computer dosing algorithm compared with dosage decided by expert physicians. Materials and methods: Nine thrombosis Italian centres utilizing the “Zeus” dosing algorithm were involved. The “before-after” study enrolled patients managed firstly by medical staff (manual system) or with “PARMA” algorithm for twelve months from July 2008 to June 2009 and then with “Zeus” algorithm during the analogous period 2010 – 2011. Out of 7605 in OAT maintenance phase, 2281 were older than 80 years (mean age: 84.2). Data of these 2281 patients managed with both modalities were analysed. Results: Out of 2281 patients 80 years of age or older, 1776 underwent OAT for atrial fibrillation (AF). Dosing algorithm increased the OAT quality: time in therapeutic range (TTR) was significantly (p<0.001) higher during the Zeus period in comparison with the TTR during manual period (71.6% vs. 68.8%). The TTR achieved with Zeus was similar to that obtained with PARMA algorithm. In addition to this, patients managed with Zeus took a drug amount significantly (p<0.01) lower than that both suggested by Parma and that prescribed by expert physicians with a reduced number of adverse events. Conclusions: This study confirms that the effectiveness and safety of VKA therapy in patients 80 years of age or older increase with computer dosing algorithms

Inherited Mutations in DNA Damage Repair Genes in Italian Men with Metastatic Prostate Cancer: Results from the Meet-URO 10 Study

Background: The prevalence of pathogenic germline mutations in DNA damage repair (gDDR) genes in the Italian population is unknown. Objective: In this prospective multicenter cohort study, we evaluated the prevalence of gDDR alterations in the Italian population affected by metastatic prostate cancer (mPCa) and analyzed the impact on response to therapy, survival, and time to castration resistance. Design, setting, and participants: In an observational prospective trial, 300 consecutive Italian mPCa patients, enrolled in the Meet-Uro-10 trial from three academic Italian centers, were recruited between 2017 and 2019 and were screened for gDDR mutations in 107 genes. Outcome measurements and statistical analysis: The primary endpoint was to assess the prevalence of gDDR mutations in the Italian population of patients with mPCa. The secondary endpoints included the association of gDDR subgroups with metastatic onset, Gleason score, and time to castration resistance. Results and limitations: We identified 297 valuable patients. Forty-six patients had a pathogenic/likely pathogenic variant (15.5%, 95% confidence interval: 11.4–19.6): the more frequent was gBRCA2 found in nine cases (3%), followed by gATM in five cases (1.7%). In patients without mutations, longer median overall survival was observed with the sequence docetaxel-androgen receptor signaling inhibitor (ARSI) than with the sequence ARSI-docetaxel (87.9 vs 42 mo, p = 0.0001). In a univariate analysis, the median time to castration resistance in gDDR mutated patients was 19.8 mo, versus 23.7 mo in no mutated patients (p = 0.024). There were no associations of gDDR subgroups with metastatic onset and Gleason score ≥8. In our cohort, variants of unknown significance in gDDR genes were found in 80 patients and might have a prognostic relevance. Conclusions: The study reported the prevalence of gDDR in the Italian population. The presence of gBRCA2 mutations correlates with a shorter time to the onset of castration resistance disease. Patient summary: The prevalence of gBRCA2 in the Italian population is 3%, which is similar to that in the Spanish population, identifying similarities between people of the Western Mediterranean area
