Sentinel Lymph Node Biopsy Versus Pelvic Lymphadenectomy in Early-stage Cervical Cancer (PHENIX/CSEM 010)

December 10, 2024 updated by: Jihong Liu, Sun Yat-sen University
The diagnostic value of sentinel lymph node biopsy in early-stage cervical cancer has been well studied. However, there were no randomized controlled study on comparing the long-term outcomes of sentinel lymph node biopsy and conventional procedure. The investigators perform a phase III, randomized controlled trial to determine whether pelvic lymphadenectomy can be replaced by sentinel lymph node biopsy in surgical treatment for patients with early-stage cervical cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study comprises two parts: PHENIX-I: To compare the outcomes of managements with and without pelvic lymphadenectomy for patients with negative sentinel lymph node; PHENIX-II: To compare the outcomes of managements with and without pelvic lymphadenectomy for patients with positive sentinel lymph node. Patients with newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage IA1 (lymphovascular space involvement), IA2, IB1, and IB2 cervical cancer are eligible for our study. The tumor diameter should be less than 3cm. Sentinel lymph node biopsy will be performed at the beginning of operations. After pathological examination of frozen section, patients will be assigned to PHENIX-I or PHENIX-II study according to their status of sentinel nodes. In both parts of this trail, patients have equal chance to be randomly assigned to experimental arms (radical hysterectomy only) and reference arms (radical hysterectomy and pelvic lymphadenectomy).Adjuvant treatments will be planned according to postoperative pathological factors. The primary objective is disease-free survival at 3 years for PHENIX-I and 2 years for PHENIX-II. The secondary end points are overall survival, long-term outcome of sentinel lymph node biopsy and the quality of life.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
