Letrozole for Estrogen/Progesterone Receptor Positive Low-grade Serous Epithelial Ovarian Cancer (LEPRE Trial) (LEPRE)
Letrozole for Estrogen/Progesterone Receptor Positive Low-grade Serous Epithelial Ovarian Cancer: a Randomized Phase III Trial (LEPRE Trial)
This is an Italian, multicenter, randomized, open-label phase III trial which will evaluate if Letrozole is superior to standard adjuvant chemotherapy in patients with hormone receptor positive low-grade serous epithelial carcinoma of the ovary (LGSCO).
The hypothesis is that letrozole will significantly prolong median progression free survival (PFS) compared with the standard chemotherapy treatment, namely carboplatin AUC 5 and paclitaxel 175 mg/m2.

Detailed Description
Primary objective:
To determine if letrozole is superior to standard chemotherapy in terms of progression-free survival (PFS) in the first line treatment of patients with advanced low-grade serous epithelial ovarian carcinoma positive for estrogen and/or progesterone receptors.
Secondary objectives:
- to evaluate the response of tumor to letrozole compared with standard chemotherapy in terms of objective response rate (ORR);
- to test the predictive effect of ER and PgR on response to letrozole in terms of PFS and ORR;
- to evaluate the possible negative association between the effect of letrozole, in terms of PFS and ORR, and the proliferative index Ki67;
- to evaluate the impact of letrozole compared with the impact of standard chemotherapy on patients' health related quality of life evaluated by Menopausal Quality of Life Questionnaire (MENQOL);
- to evaluate the impact of letrozole compared with standard chemotherapy on patients' musculoskeletal pain evaluated by Brief Pain Inventory - Short Form (BPISF);
- to evaluate the effect on overall survival (OS). As most patients will recur and will be switched to chemotherapy and vice versa, OS is not expected to be significantly different;
- to evaluate the safety of letrozole compared with standard chemotherapy according to CTCAE v 5.0.
Translational objectives:
- to characterize the mutational profile and gene expression of the disease by NGS (next-generation sequencing) methodology on tissue samples;
- to evaluate the circulating tumor DNA (ctDNA) on liquid biopsies as a tool to monitor the disease response.

Inclusion Criteria:
I - 1. Age ≥ 18 years. I - 2. Newly diagnosed, low-grade serous carcinoma of the ovary including cancer of fallopian tube and peritoneum (invasive micropapillary serous carcinoma or invasive grade 1 serous carcinoma). This is to be confirmed via nuclear p53 immunohistochemistry testing by a central pathology review performed at the Coordinating Centre.

- Patients must have undergone contrast-enhanced CT-scan of the chest, abdomen and pelvis within 28 days prior to randomization. If CT-scan is not recommended (e.g. for allergy to contrast agent) MRI or 18F-FDG PET/CT-scan are allowed.
- The imaging evaluation must be accompanied by an anamnestic and physical examination within 14 days prior to randomization.
