Study Description

Brief Summary:

The goal of this surgical research study is to learn if "conservative surgery" is a safe and feasible option for women with low-risk cervical cancer (stage IA2 or IB1, Grade 1 or 2).

Condition or disease	Intervention/treatment	Phase
Cervical Cancer	Procedure: Conservative Surgery	Phase 2

Detailed Description:

Stage IA2 or IB1 cervical cancer is currently treated by a radical hysterectomy (removal of the uterus, cervix, and the parametrium) or radical trachelectomy (removal of the cervix and the parametrium). The parametrium is the tissue next to the uterus and cervix that holds these organs in place. Pelvic lymph nodes and possibly para-aortic lymph nodes (near the aorta in the abdomen) are also removed. This procedure is called a pelvic and para-aortic lymphadenectomy. While these surgeries are very effective, significant side effects can occur, such as bladder, bowel, and/or sexual dysfunction.

Conservative surgery involves the removal of the pelvic lymph nodes (pelvic lymphadenectomy) and/or lymphatic mapping with sentinel lymph node biopsy. The cervix and parametrium are left intact. During surgery, for women no longer wanting children, a simple hysterectomy (removal of the uterus with or without removal of the fallopian tubes and ovaries) can also be performed. In this study, participants will have conservative surgery.

Screening Tests:

Signing this consent form does not mean that you will be able to take part in this study. You will have "screening tests" to help the doctor decide if you are eligible to take part in this study. The following tests and procedures will be performed:

You will have a cervical cone biopsy and endocervical curettage (ECC) performed. A cone biopsy is surgery to remove a cone-shaped piece of tissue from the cervix and cervical canal. It is used to diagnose cervical cancer and also to learn how extensive the disease is. An ECC is a procedure using a curette, a spoon-shaped instrument, that is used to scrape the mucus membrane of the endocervical canal (passageway between cervix and uterus) in order to get a tissue sample.

The tissue taken from both of these procedures will be reviewed by a pathologist from MDAnderson.

If your tissue samples are negative for invasive cancer or adenocarcinoma-in-situ (AIS), you will be eligible for conservative surgery.

If your tissue samples are positive for invasive cancer and/or AIS, you may have the cervical cone biopsy and ECC repeated. If the tissue samples are negative after the second procedure, you will be eligible for conservative surgery. If your tissue samples from the second procedure are positive, you will be removed from study and other treatment options will be offered.

Conservative Surgery:

If you are found to be eligible to take part in this study, you will have conservative surgery. You will be taken to the operating room where you will be put to sleep using general anesthesia. You will have your pelvic lymph nodes removed by pelvic lymph node dissection and/or lymphatic mapping with sentinel lymph node biopsy, however, the parametrium is left intact. If you no longer want to have children, you can have a simple hysterectomy. Removal of the pelvic lymph nodes takes about 1-2 hours. If you also decide to have a simple hysterectomy, this procedure will take about 2 hours.

You will sign a separate consent for this surgery/procedure, which will discuss the risks in more detail.

Study Procedures:

If you agree to take part in this study, the following information will be collected from your medical record and/or you will be asked for this information when you enroll in the study:

• Age at the time of the cancer diagnosis
• Race
• Height and weight to determine body mass index (BMI)
• Menopausal status
• Symptoms
• History of sexually transmitted diseases
• Smoking history
• Child bearing history

The following information will be collected from your medical record and/or you will be asked for this information after surgery:

• How long the surgery took to complete
• What procedures were performed during the surgery
• How long you were in the hospital
• If there was any blood loss before or after surgery
• If blood transfusions were performed before or after surgery
• What complications, if any, happened that were related to the surgery

Starting 3 months after your first visit after surgery, you will have study visits every 3 months for 2 years. At these visits, the following tests and procedures will be performed:

• You will have a physical exam.
• You will have a pelvic exam.
• You will have a pap smear.

You will be contacted by telephone or by mail every year for 3 years. You will be asked if the cancer has returned, when you last saw your doctor, and any complications or problems you may be having. If you are called, the call will take less than 10 minutes.

Length of Study:

You may remain on study for 5 years after surgery. You will be taken off study early if either the lymph nodes or cervix (if a simple hysterectomy was performed) removed during surgery contain cancer.

This is an investigational study. Up to 195 patients will take part in this multicenter study. Up to 40 participants will be enrolled at MD Anderson and the Harris Health System.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Conservative Surgery; Removal of the pelvic lymph nodes (pelvic lymphadenectomy)	Procedure: Conservative Surgery; Removal of the pelvic lymph nodes (pelvic lymphadenectomy); Other Name: pelvic lymphadenectomy

Outcome Measures

Primary Outcome Measures :

1. Immediate Failure Rate [ Time Frame: 5 Years ]
   The immediate failure rate is defined as residual disease in the simple hysterectomy specimen.

Secondary Outcome Measures :

1. Cervix Cancer Recurrence Rate [ Time Frame: At 2 Years ]
   Recurrence rate estimated at 2 years with an exact 95% binomial confidence interval. If study completed with 100 patients and only 1 patient with recurrence by 2 years following completion of therapy, estimate of the recurrence rate at 2 years will be 0.05% to 4.92%.

Eligibility Criteria

• Ages Eligible for Study: Child, Adult, Older Adult
• Sexes Eligible for Study: Female
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

1. Histologically confirmed squamous cell carcinoma of the cervix (any grade) or Histologically confirmed grade 1 or 2 adenocarcinoma of the cervix
2. FIGO stage IA2 or IB1 disease
3. Tumor diameter </= 2 cm on physical exam and on imaging studies
4. No lymphovascular space invasion (LVSI) present on biopsy or previous cone
5. Less than 10mm of cervical stromal invasion
6. Cone margins and endocervical curettage (ECC) specimen negative for invasive cancer, cervical intraepithelial neoplasia (CIN) CIN II, CIN III or adenocarcinoma-in-situ. (A negative margin is defined as no invasive cancer within 1.0mm of both the endocervical and ectocervical margins and no AIS or CIN II or CIN III at the inked or cauterized margin; one repeat cone and ECC permitted)
7. Patients are eligible for the study when a cone and ECC are performed prior to pre-enrollment in the study, and pathologic eligibility criteria are met. The cone and ECC must be performed within 12 weeks prior to pre-enrollment in the study. If the cone and ECC performed prior to pre-enrollment do not meet the pathologic criteria, patients may be pre-enrolled and are allowed 1 repeat cone & ECC after pre-enrollment in order to meet pathologic eligibility criteria.

9. If patient is of childbearing potential, she must have a negative blood or urine pregnancy test within 14 days of surgical treatment on study.
