ULTRA-LAP Trial: Laparoscopic Debulking Surgery (LDS) in Advanced Ovarian Cancer: a Feasibility Prospective Study

Обзор

ULTRA-LAP is a prospective study is to investigate the safety, efficacy and feasibility of laparoscopic debulking surgery (LDS) for the treatment of patients with advanced ovarian cancer. The outcomes to measure are: * Safety: the rate of patients experiencing intra- and post-operative early and late morbidities (within the hospitalization and up to 60 days from surgery) * Efficacy: the rate of patients in which the surgical target set pre-operatively (complete resection) is achieved by laparoscopy. * Feasibility: the rate of patients who have their procedure completed by laparoscopy Patients will undergo laparoscopic debulking surgery (LDS) if the surgical target can be met. If it cannot be achieved by laparoscopy the surgeon will convert to laparotomy.

Подробное описание

The investigators intend to perform a prospective feasibility study on patients with primary diagnosis of advanced ovarian cancer (stage II to IV according to FIGO classification) who are referred to the tertiary cancer centre of the study. The latter is the Department of Gynecology and Obstetrics - Division of Women's and Children's Health - University of Padova - Italy. The statistical sample size calculation identified a minimum of 62 patients. The anticipated enrollment period will be about 4 years.

To confirm the ultimate eligibility to surgery and recruitment in the study, all patients undergo an exploratory laparoscopy (EXL).

The ideal surgical target is complete resection (CR) of all visible disease. Patients who are deemed not amenable to a CR at EXL will start neo-adjuvant chemotherapy. They will be reconsidered for the ULTRA-LAP study at time of interval surgery after 3 cycles of chemotherapy. Criteria for eligibility after neo-adjuvant chemotherapy are the same as per up-front surgery.

All patients recruited in the ULTRA-LAP trial will be discussed at Gynaecologic Oncology Multidisciplinary team (MDT) meeting, where imaging is reviewed and management is agreed. Following MDT decision:

* A Gynaecologic Oncologist will discuss the standard management and the ULTRA-LAP trial at time of out-patient clinic * The ULTRA-LAP leaflet and consent form will be provided to the patient together with an accurate explanation of the study * If the patient accepts to enter the study, a study registration form will be filled * Participation in the study will be confirmed and the forms signed at time of pre-operative assessment and again confirmed at time of in-patient admission ULTRA-LAP trail will include all surgical procedures necessary to accomplish a complete resection (CR) of disease. The most common procedures necessary to obtain a CR are defined by The European Society of Gynaecological Oncology (ESGO), Society of Gynecologic Oncology (SGO) and the The National Institute for Health and Care Excellence (NICE) guidelines. All procedures will be performed by an expert Gynaecologic Oncologist with proven experience and high skills levels in oncological surgery. Once the surgeon realizes that a CR could not be achieved by laparoscopy, but prove to be feasible by laparotomy, the surgery is immediately converted to laparotomy.

Subsequent follow-up:

1. During Recovery:

\- The patients are going to be monitored daily and any relevant complications will be registered, graded (according to Clavien-Dindo classification) and treated. 2. Post recovery:

* 1 st follow-up visit: At time of hospital's discharge an examination will be performed and, if necessary, further exams will be prescribed as appropriate. * 2 nd follow-up visit: following discharge, the next appointment is in the outpatient clinic roughly 15-20 days from the surgery. * 3 rd and last visit: at 30 days from the surgery a further appointment will be carried.

At each follow-up appointment the following will be registered:

* Occurrence of complications * Physical examination * Changes in normal quality of life.

Achievement of a CR will be determined at time of surgery and confirmed by a pre-chemotherapy CT scan. Should discrepancy arise, CT scan will be reviewed at MDT.

All patients will be closely monitored with a rigorous follow-up program every 90 days for the first two years and then every 120 days for the subsequent 2 years. In addition, all patient could contact the department if any unexpected complications happens between follow-up time.
