Retrospective Multicenter Study of Elderly Patients With Ovarian Cancer Treated With Trabectedin and PLD

Study Overview
=================
Brief Summary
-----------------
The median age at which ovarian cancer is diagnosed is 63 years (50-75). This is still a significant adverse factor for survival results. Seventy years can be considered the lower limit for the elderly term, since most of age-related changes occur later. Because of this, this group of patients is often not included in clinical trials and sometimes they do not receive adequate treatment. Little information is available on chemotherapy treatments in elderly patients. Data on the use of first-line chemotherapy in this population have recently been published. Trabectedin in combination with PLD is indicated for platinum-sensitive relapsed ovarian cancer and is an option for those patients in whom platinum is not the best option. There are some studies with trabectedin in combination with PLD in which some patients with this profile have been included, although not exclusively. Therefore, it is of interest to study the safety and efficacy profile of this treatment in elderly patients. With this information we will be able to know its real use in routine clinical practice at the national level in Spain in this population for which not much information is available. Safety and efficacy data (e.g. PFS, ORR, OS) will be collected retrospectively in order to draw conclusions about the combination of trabectedin + PLD, as a treatment option in this patient profile.

Eligibility Criteria
-----------------
Inclusion Criteria: Written informed consent must be signed by all patients participating in the study who can be interviewed in the hospital (accessible, alive patients) or absence of consent sheet must be signed by the investigator. Informed consent may not be required from unaccesible patients (dead, lost, etc.) according to ethics committee permissions and applicable law for retrospective studies in Spain. Adult women (≥70 years at the time of treatment initiation with trabectedin and PLD). Histological diagnosis of platinum-sensitive relapsed ovarian cancer (PFI ≥ 6 months). Treatment started with trabectedin and PLD (at least one cycle) as standard of care between January 1st 2015 and December 31st 2019. Patients must have received at least one cycle of trabectedin + PLD. Exclusion Criteria: Patients without medical record available (lost, empty or unretrievable clinical information). Patients who explicitly refuse to participate in the study.
