Genomic instability analysis in DNA from Papanicolaou test provides proof-of-principle early diagnosis of high-grade serous ovarian cancer

Late diagnosis and the lack of screening methods for early detection define high-grade serous ovarian cancer (HGSOC) as the gynecological malignancy with the highest mortality rate. In the work presented here, we investigated a retrospective and multicentric cohort of 250 archival Papanicolaou (Pap) test smears collected during routine gynecological screening. Samples were taken at different time points (from 1 month to 13.5 years before diagnosis) from 113 presymptomatic women who were subsequently diagnosed with HGSOC (pre-HGSOC) and from 77 healthy women. Genome instability was detected through low-pass whole-genome sequencing of DNA derived from Pap test samples in terms of copy number profile abnormality (CPA). CPA values of DNA extracted from Pap test samples from pre-HGSOC women were substantially higher than those in samples from healthy women. Consistently with the longitudinal analysis of clonal pathogenic TP53 mutations, this assay could detect HGSOC presence up to 9 years before diagnosis. This finding confirms the continual shedding of tumor cells from fimbriae toward the endocervical canal, suggesting a new path for the early diagnosis of HGSOC. We integrated the CPA score into the EVA (early ovarian cancer) test, the sensitivity of which was 75% (95% CI, 64.97 to 85.79), the specificity 96% (95% CI, 88.35 to 100.00), and the accuracy 81%. This proof-of-principle study indicates that the early diagnosis of HGSOC is feasible through the analysis of genomic alterations in DNA from endocervical smears.

Effectiveness of Intensive Versus Minimalist Follow-Up Regimen on Survival in Patients With Endometrial Cancer (TOTEM Study): A Randomized, Pragmatic, Parallel Group, Multicenter Trial

PURPOSE In the absence of clear evidence from randomized trials, the intensity of follow-up regimens after surgical treatment of endometrial cancer is highly variable in clinical practice. To reduce this uncertainty, we conducted a randomized trial to test whether an intensive (INT) versus a minimalist (MIN) follow-up regimen improves overall survival (OS) in patients undergoing operation for endometrial cancer. METHODS The TOTEM study was a large, pragmatic randomized trial, conducted in 42 hospitals (in Italy and France) including patients surgically treated for endometrial cancer, in complete clinical remission, International Federation of Gynecology and Obstetrics stage I-IV. After stratification by center and risk of relapse (low or high), patients were randomly assigned (1:1) to INT or MIN hospital-based follow-up regimens. The study was powered to demonstrate an absolute improvement of 5% of the 5-year OS with the INT regimen. RESULTS In total, 1,871 patients were randomly assigned between November 2008 and July 2018, and 1,847 patients (98.7%) were available for the final analysis (60% low risk). After a median follow-up of 69 months, the 5-year OS was 90.6% in the INT and 91.9% in the MIN arms (hazard ratio, 1.13, 95% CI, 0.86 to 1.50, P = .380). No differences in OS were found in subgroup analyses considering age, cancer treatment, risk of relapse, and degree of adherence of the center to the scheduled follow-up. The probability of detecting a relapse was slightly higher in the INT arm (hazard ratio, 1.17; 95% CI, 0.92 to 1.48; P = .194). CONCLUSION An INT follow-up in endometrial cancer–treated patients does not improve OS, even in high-risk patients. According to available evidence, there is no need to routinely add vaginal cytology, laboratory, or imaging investigations to the MIN regimens used in this trial.

Trial Between Two Follow up Regimens With Different Test Intensity in Endometrial Cancer Treated Patients

This study aims to compare two different follow up regimens with different test intensity in endometrial cancer treated patients. If eligibility criteria are satisfied and the written informed consensus is obtained, patients are stratified inside the centre according to their risk level: * Group 1 : patients at low risk of recurrence \[stage IA G1 and stage IA G2\] * Group 2 : patients at high-risk of recurrence \[≥ stage IA G3\] (Ethics Committee amendment of 14th September 2010, use new 2010 FIGO classification for endometrial cancer!) In each group patients will be randomized in two regimens of follow up: 1. Minimalist (Arm 1) 2. Intensive (Arm 2) Features of each arm are listed in "Arms" item.
