Study Overview
Brief Summary
An international worldwide retrospective cohort observational study comparing primary cytoreductive surgery with neoadjuvant chemotherapy and interval cytoreductive surgery in patients with carcinoma of the ovary, fallopian tubes, and peritoneum.
Detailed Description
SUROVA study tries to compare the outcomes of primary cytoreductive surgery with neoadjuvant chemotherapy and interval cytoreductive surgery in patients with carcinoma of the ovary, fallopian tubes, and peritoneum operated between 2018 and 2019 worldwide.
The objective is to know if the surgical approach influences our patients' survival (OS and PFS). To answer this question, SUROVA is necessary.
While the prospective Trust Trial, with results expected in 2024, is designed to address this question, a limitation of this study is that it is confined to patients treated in high-end hospitals. This limitation could introduce bias in the results, as many patients may lack access to such high-level healthcare facilities. Therefore, the objective is to extend the scope of this study to real life. To achieve this, the investigators are seeking to collect data from patients treated globally during 2018 and 2019, involving both primary and interval cytoreduction.
The investigators hope that the results of this study will be subjected to evaluation at international meetings and published in reputable international journals. Authorship will be based on a rigorous criterion tied to the number of valid cases included in the study. Naturally, the aim is to include as many authors as possible.
The researchers strongly believe that patients would greatly benefit from SUROVA data and that it will address this critical question and provide invaluable insights.

Arms & Interventions
Primary cytoreductive surgery
Patients underwent primary cytoreductive surgery between January 1, 2018, and December 31, 2019. After that, they underwent adjuvant therapy.
Intervention: Adjuvant chemotherapy (Drug)
Interval cytoreductive surgery
Patients underwent primary first course of neoadjuvant chemotherapy between January 1, 2018, and December 31, 2019. After neoadjuvant chemotherapy, the patient underwent interval cytoreductive surgery and then, adjuvant chemotherapy.
Intervention: Neoadjuvant chemotherapy (Drug)
Primary cytoreductive surgery
Patients underwent primary cytoreductive surgery between January 1, 2018, and December 31, 2019. After that, they underwent adjuvant therapy.
Intervention: Cytoreductive surgery (Procedure)
Interval cytoreductive surgery
Patients underwent primary first course of neoadjuvant chemotherapy between January 1, 2018, and December 31, 2019. After neoadjuvant chemotherapy, the patient underwent interval cytoreductive surgery and then, adjuvant chemotherapy.
Intervention: Cytoreductive surgery (Procedure)
Interval cytoreductive surgery
Patients underwent primary first course of neoadjuvant chemotherapy between January 1, 2018, and December 31, 2019. After neoadjuvant chemotherapy, the patient underwent interval cytoreductive surgery and then, adjuvant chemotherapy.
Intervention: Adjuvant chemotherapy (Drug)
Outcomes
Primary Outcomes
Overall Survival at 5 years
Time Frame: From date of the first treatment (chemotherapy in the case of neoadjuvant chemotherapy and cytoreduction in the case of primary cytoreductive surgery) to death from ovarian cancer or last follow up, assessed at the 5-year mark.
Compare overall survival (OS) at 5 years in patients who underwent primary cytoreductive surgery vs. neoadjuvant chemotherapy and interval cytoreductive surgery for stage IIIB-IVB ovarian cancer.
Secondary Outcomes
- Time to first and second subsequent anticancer therapy or death.(From date of the first treatment (chemotherapy in the case of neoadjuvant chemotherapy and cytoreduction in the case of primary cytoreductive surgery) to death from ovarian cancer or last follow up assessed at the 5-year mark.)
- Aletti surgical score(Date of last contact up to 5 years)
- Surgical complications: requirement of pharmacological treatment; surgical, endoscopic or radiological intervention, life threatening complications or death.(Date of last contact up to 5 years)
- Progression Free Survival at 5 years(From date of the first treatment (chemotherapy in the case of neoadjuvant chemotherapy and cytoreduction in the case of primary cytoreductive surgery) to death from ovarian cancer or last follow up assessed at the 5-year mark.)
- Information on surgical treatment approaches(Date of last contact up to 5 years)
- Breast cancer susceptibility gene (BRCA) influence(Date of last contact up to 5 years)
- Homologous Recombination Deficiency (HRD) deficiency influence(Date of last contact up to 5 years)
