Sonographic, Demographic, and Clinical Characteristics of Pre- and Postmenopausal Women with Endometrial Cancer; Results from a Post Hoc Analysis of the IETA4 (International Endometrial Tumor Analysis) Multicenter Cohort

In this study, we conducted a comparative analysis of demographic, histopathological, and sonographic characteristics between pre- and postmenopausal women diagnosed with endometrial cancer, while also examining sonographic and anthropometric features in 'low' and 'intermediate/high-risk' cases, stratified by menopausal status. Our analysis, based on data from the International Endometrial Tumor Analysis (IETA) 4 cohort comprising 1538 women (161 premenopausal, 1377 postmenopausal) with biopsy-confirmed endometrial cancer, revealed that premenopausal women, compared to their postmenopausal counterparts, exhibited lower parity (median 1, IQR 0-2 vs. 1, IQR 1-2, p = 0.001), a higher family history of colon cancer (16% vs. 7%, p = 0.001), and smaller waist circumferences (median 92 cm, IQR 82-108 cm vs. 98 cm, IQR 87-112 cm, p = 0.002). Premenopausal women more often had a regular endometrial-myometrial border (39% vs. 23%, p < 0.001), a visible endometrial midline (23% vs. 11%, p < 0.001), and undefined tumor (73% vs. 84%, p = 0.001). Notably, despite experiencing a longer duration of abnormal uterine bleeding (median 5 months, IQR 3-12 vs. 3 months, 2-6, p < 0.001), premenopausal women more often had 'low' risk disease (78% vs. 46%, p < 0.001). Among sonographic and anthropometric features, only an irregular endometrial-myometrial border was associated with 'intermediate/high' risk in premenopausal women. Conversely, in postmenopausal women, multiple features correlated with 'intermediate/high' risk disease. Our findings emphasize the importance of considering menopausal status when evaluating sonographic features in women with endometrial cancer.

NGR-hTNF and doxorubicin in relapsed ovarian cancer (OC)

5059

Background: NGR-hTNF (asparagine-glycine-arginine human tumor necrosis factor) is able to promote antitumor immune responses and to improve the intratumoral doxorubicin (D) uptake by selectively damaging tumor vessels. Methods: OC patients (pts) with progressive disease (PD) after ≥ 1 platinum/taxane regimen and with a platinum free interval lower than 6 months (PFI <6) or ranging from 6 to 12 months (PFI 6-12) received NGR-hTNF (N) 0.8 µg/m2 and D 60 mg/m2 on day 1 every 3 weeks. Primary endpoint of this phase 2 trial was response rate by RECIST criteria with a target of ≥ 6/37 responding pts. Secondary aims were progression free survival (PFS) and overall survival (OS). Results: 37 pts (median age 57 years; PS 0/1 32/5; PFI < 6/6-12 25/12; prior regimens 1-5) were enrolled. Median baseline peripheral blood lymphocyte count (PBLC) was 1.6/mL (interquartile range 1.2-2.1). In all, 177 cycles were given, with 18 pts (49%) receiving ≥ 6 cycles and 12 pts (32%) 8 cycles. Neither grade 3/4 adverse events (AEs) related to N nor increase of D-related AEs were noted. Common grade 1/2 AEs included chills (65%). Eight pts (23%; 95% CI 12-39) had partial response (PR; 2 with PFI < 6 and 6 with PFI 6-12; median duration: 8.2 months). Fifteen pts had stable disease (SD, 43%; 10 with PFI < 6 and 5 with PFI 6-12; median duration: 4.9 months) for an overall disease control (DC, PR+SD) rate of 66%. Mean changes from baseline in target tumor size after 2, 4, 6, and 8 cycles were 2%, -54%, -69%, and -77%, respectively. Median PFS was 5.0 months (95% CI 3.1-6.9) and median OS was 17.0 months (10.4-23.6). In pts with PFI < 6 or 6-12, median PFS were 3.8 and 7.8 months (p=.03) and median OS were 14.3 and 20.1 months (p=.14), respectively. Pts with DC had longer median OS than those with early PD (24.0 and 4.9 months, respectively, p=.02). Longer PFI (p=.03) and higher PBLC (p=.01) were associated with better PFS, while OS correlated only with PBLC (p=.001). In the subset with PFI < 6, pts with PBLC ≥ or < 1.2/mL (1st quartile) had median PFS of 4.9 and 2.6 months (p=.02) and median OS of 15.8 and 4.3 months (p=.0001), respectivel Conclusions: A randomized phase II trial is currently testing D ± NGR-hTNF in pts with PFI < 6 (refractory/resistant). The role of PBLC as blood-based biomarker deserves further investigation.
