Brief summary

This clinical trial studies conservative surgery in treating patients with low-risk stage IA2 or IB1 cervical cancer. Conservative surgery is a less invasive type of surgery for early stage cervical cancer and may have fewer side effects and improve recovery.

Detailed description

PRIMARY OBJECTIVE: I. To evaluate the safety and feasibility of performing conservative surgery in women with stage IA2 or IB1 carcinoma of the cervix with favorable pathologic features. SECONDARY OBJECTIVES: I. To estimate the cervix cancer recurrence rate at 2 years in women treated with conservative surgery for stage IA2 or IB1 carcinoma of the cervix with favorable pathologic features. II. To compare pelvic lymph node involvement in patients undergoing conservative surgery with historical data from matched patients treated with radical hysterectomy. III. To estimate the sensitivity of sentinel lymph node biopsy in the determination of pelvic lymph node metastases in this group of patients. IV. To compare the treatment-associated morbidity in patients undergoing conservative surgery with historical data from matched patients treated with radical hysterectomy. V. To assess quality of life factors, sexual functioning, symptoms and satisfaction with healthcare decisions in this group of patients. OUTLINE: Patients undergo a complete lymphatic mapping with sentinel lymph node biopsy and/or pelvic lymph node dissection. If future fertility is no longer desired, patients also undergo hysterectomy with or without bilateral salpingo-oophorectomy. After completion of study treatment, patients are followed up every 3 months for 2 years and then yearly for 3 years.

Inclusion criteria

* Histologically confirmed squamous cell carcinoma of the cervix (any grade) or histologically confirmed grade 1 or 2 adenocarcinoma of cervix * International Federation of Gynecology and Obstetrics (FIGO) stage IA2 or IB1 disease * Tumor diameter =\< 2 cm on physical exam and on imaging studies * No lymphovascular space invasion (LVSI) present on biopsy or previous cone * Less than 10 mm of cervical stromal invasion * Cone margins and endocervical curettage (ECC) specimen negative for invasive cancer, cervical intraepithelial neoplasia (CIN) II, CIN III or adenocarcinoma-in-situ; (a negative margin is defined as no invasive cancer within 1.0 mm of both the endocervical and ectocervical margins and no adenocarcinoma in situ \[AIS\] or CIN II or CIN III at the inked or cauterized margin; one repeat cone and ECC permitted) * 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 * Patients must sign an approved informed consent document * If patient is of childbearing potential, she must have a negative blood or urine pregnancy test within 14 days of surgical treatment on study * Imaging with positron emission tomography (PET) scan, computed tomography (CT) scan of the abdomen and pelvis, and/or magnetic resonance imaging (MRI) of the abdomen and pelvis must be performed and negative for metastatic disease within 12 weeks of enrollment

Outcome results

Primary

Safety and Feasibility of Performing Conservative Surgery in Women With Stage IA2 or IB1 Carcinoma of the Cervix With Favorable Pathologic Features

The proposed treatment strategy will be considered not feasible if the immediate failure rate is more than 3%. The immediate failure rate, defined as residual disease in the simple hysterectomy specimen of women who underwent conization followed by simple hysterectomy and lymph node assessment.

Time frame: Approximately 9 years

Population: Fertility Sparing - hysterectomy not performed. Simple Hysterectomy - hysterectomy performed prior to study enrollment.~Conization + hysterectomy + lymph node assessment group was only group assessed as Fertility Sparing did not have hysterectomy and the Simple Hysterectomy group had hysterectomy performed prior to study enrollment making them inevaluable.

Cervix Cancer Recurrence Rate at 2 Years in Women Treated With Conservative Surgery for Stage IA2 or IB1 Carcinoma of the Cervix With Favorable Pathologic Features

Recurrence rate was estimated and was measured from the date of surgery to the earliest date of the last clinic visit, date of first recurrence, or date of death.

Time frame: 2 years

Population: Only 42 participants out of 44 in the fertility sparing group were evaluated; 1 participant expired following the surgical procedure and 1 participant was lost to follow up prior to the 2 year interval. In the conization + hysterectomy group, 4 participants of the 40 in this group were lost to follow up prior to the 2 year interval.
