Detailed Description

SUCCOR study tries to understand the outcomes of European patients with stage IB1 cervical cancer (FIGO 2009) (1), that underwent a radical hysterectomy for cervical cancer in 2013-2014 within the ESGO area. 1.-Pecorelli, S. Revised FIGO staging for carcinoma of the vulva, cervix, and endometrium. Int J Gynaecol Obstet 105, 103-104 (2009). Investigators want to know if the different surgical approaches may influence patients' survival (DFI and OS). A recent randomized phase III clinical trial, the LACC trial, conducted by Dr. Pedro Ramirez, was recently published in the NEJM.https://www.nejm.org/doi/pdf/10.1056/NEJMoa1806395 The LACC trial ran at 33 centers in 12 countries, including six US centers. The study, randomized women during 2008-2017 who had stage 1A1, 1A2, or 1B1 cervical cancer to either MIS or open surgery for a radical hysterectomy. The study's primary endpoint was disease-free survival at 4.5 years. The results favored significantly open surgery. Just after this report, the results from a second study by Dr. Jose Alejandro Rauh-Hain, that used observational data from the US National Cancer Database found significantly worse overall survival following minimally invasive radical hysterectomy for early-stage cervical cancer, compared with laparotomy. Also, Dr. Daniel Jacob Margul et al. presented during the last ASCO meeting their results from the Premier Health Database and the US National Cancer Database showing among women with >2 cm stage IB1 cervical cancer that MIS was associated with significantly decreased survival. Likewise, these two studies have been as well published together along with the LACC trial in the same issue of NEJM. In a recent survey conducted by the investigators and supported by ESGO, many of respondents showed the determination of collaborating in this observational project. In Europe, it has not been recently not carried out any relevant large study comparing the different forms of surgical treatment of early cervical cancer. The design of a randomized clinical trial in the coming years on this subject will face severe difficulties to convince ethics committees after the results of the last clinical trial. Therefore, in the meantime, investigators consider it crucial to carry out a highly controlled European retrospective study that allows drawing satisfactory conclusions to make rational decisions on the treatment of early cervical cancer. Investigators have selected a thorough list of inclusion and exclusion criteria along with a precise questionnaire trying to avoid confounding variables. As you will realize, we will only include patients stage IB1(<4 cm, FIGO 2009), with preoperative MRI and with some requirements on the pathological report. For instance, patients that underwent conization are excluded. HOW TO PARTICIPATE 1. Only centers belonging to the ESGO area can participate in the study 2. To accept the participation in the study as principal investigator (PI) of your institution (only one PI by each institution), the participant has to fill the application form included in the following link https://forms.gle/2WPhzrkxyFPodmDq5 3. As soon a center joins the study, the local PI will receive a Center Identification code and e-mail with instructions, allowing the data collection. 4. PI the will be allowed starting to collect data of consecutive cervical cancer patients operated in 2013 and 2014 in your center that meet the inclusion and exclusion criteria. (Appendix 2). 5. For collecting data, the online questionnaire can be reached in the following link: https://forms.gle/H1hCqXoC7G2EdWc79 6. Every time submit each a complete form, you will receive an e-mail with the confirmation and a copy of your response. For sending the form, you have to fill at least the required items. You are allowed to re-edit your answers later. 7. Investigators want to complete the data collection in less than six months. 8. The principal investigator will be available for any doubt by e-mail (lchiva@unav.es), or also by phone (+34630232947) 9. Besides, all the support documents will be sent to participants PUBLICATIONS The results of this study will be submitted for evaluation to international meetings and publication in a relevant international journal. Authorship will include investigators following strict criteria, considering the introduced number of cases in the study by each investigator. Furthermore, to count with as many authors as possible, researchers will create a Succor Research Study Group that will offer authorship when the investigators cannot allocate among the first authors At the time of the publication, we will follow the STROBE guidelines for observational studies. (2) STROBE stands for an international, collaborative initiative of epidemiologists, methodologists, statisticians, researchers and journal editors involved in the conduct and dissemination of observational studies, with the common aim of STrengthening the Reporting of OBservational studies in Epidemiology.

SUMMARY The primary goal of the study is to know the outcomes of European patients that underwent radical surgery for stage IB1 cervical cancer (Open vs. MIS) during years 2013 and 2014.

Interventions

• Procedure: RADICAL HYSTERECTOMY
  • Radical hysterectomy is an operation done to treat some cancers of the cervix. The surgeon takes out the uterus and the ligaments (tissue fibers) that hold it in place. The cervix and an inch or 2 of the vagina around the cervix are also removed.

Arms, Groups and Cohorts

• LAPAROTOMY
  • Radical hysterectomy by laparotomy
• MINIMALLY INVASIVE SURGERY
  • Radical hysterectomy by minimally invasive surgery (Laparoscopy or Robotics)

Clinical Trial Outcome Measures

Primary Measures

• Disease-free survival at 4.5 years
  • Time Frame: From date of surgery for cervical cancer (Radical Hysterectomy) until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 84 months
  • Compare disease-free survival at 4.5 years in patients who underwent a laparoscopic or robotic radical hysterectomy (MIS) vs. abdominal radical hysterectomy (TARH) for stage IB1 cervical cancer.

Secondary Measures

• Overall survival Overall survival at 5 years between groups.
  • Time Frame: months until the date of first documented date of death from any cause or the date last contact if case patient is alive, assessed up to 84 months
  • Compare overall survival at 5 years in patients who underwent a laparoscopic or robotic radical hysterectomy (MIS) vs. abdominal radical hysterectomy (TARH) for stage IB1 cervical cancer.
• Patterns of recurrence
  • Time Frame: Through study completion, an average of 1 year
  • Compare patterns of recurrence between groups.
• Rate of surgical complications during the first 30 days after surgery
  • Time Frame: 30 days after surgery
  • Compare treatment-associated morbidity (30 days after surgery ) between groups
