In a patient with early-stage cervical cancer (stage IA2–IB1) desiring fertility preservation, what are the indications, procedural steps, and postoperative considerations for a radical trachelectomy?

Radical Trachelectomy for Early-Stage Cervical Cancer with Fertility Preservation

Radical trachelectomy with pelvic lymphadenectomy is the recommended fertility-sparing procedure for carefully selected patients with stage IA2 (with LVSI) to IB1 cervical cancer, with optimal candidates having tumors ≤2 cm confined to the cervix. 1, 2, 3

Patient Selection Criteria (Indications)

Ideal Candidates:

• Stage IA2 with LVSI or stage IB1 disease 1, 2
• Tumor size ≤2 cm for vaginal approach 2, 3
• Tumor size 2-4 cm may be considered for abdominal approach (laparotomy, laparoscopic, or robotic), though these patients require careful selection as many will need adjuvant therapy due to pathologic risk factors 2, 3
• Tumor location >1 cm from internal cervical os (some centers accept ≥0.5 cm) 4
• Disease confined to cervix confirmed by imaging (MRI and/or PET/CT) 4
• Negative pelvic lymph nodes on preoperative assessment 2, 3
• Desire for future fertility 1

Absolute Contraindications:

• Small cell neuroendocrine histology 3
• Gastric type adenocarcinoma 3
• Adenoma malignum 3
• Known lymph node metastases 2, 3
• Parametrial invasion 4

Histology Considerations:

The most common histologies treated are adenocarcinoma (55%) and squamous cell carcinoma (43%), with lymphovascular space invasion present in approximately 39% of cases 5. These features do not preclude the procedure but require careful patient counseling.

Procedural Steps

Preoperative Assessment:

1. Imaging: MRI to assess tumor size, stromal invasion, and local extension; PET/CT to rule out extrapelvic disease 1, 4
2. Sentinel lymph node mapping can be considered as an alternative to complete lymphadenectomy 3

Surgical Technique (Laparoscopic-Assisted Vaginal Approach):

First Laparoscopic Phase:

• Bilateral pelvic lymphadenectomy (median 22 nodes evaluated) 5
• Opening of paravesical and pararectal fossae 6, 7
• Ureteral identification and bilateral ureterolysis under direct vision 6, 7
• Opening of vesicouterine and rectovaginal spaces 6
• Division of uterosacral ligaments approximately 20 mm from uterine insertion 7
• Parametrectomy (resection of parametrial tissue) 6, 7

Vaginal Phase:

• Colpotomy performed vaginally 6
• Cervix closed in vaginal cuff to prevent tumor spread 6
• Careful dissection of anterior and posterior septa until reunification with laparoscopic dissection 6
• Vaginal trachelectomy with negative deep margin confirmed by frozen section 6

Second Laparoscopic Phase:

• Prophylactic cerclage placement: Monofilament polypropylene sling positioned bilaterally through broad ligaments, fixed anteriorly on uterine isthmus 6
• Laparoscopic isthmovaginal suturing 7
• Peritoneal closure 7

Alternative Approaches:

• Abdominal radical trachelectomy (open, laparoscopic, or robotic) for larger tumors (2-4 cm) 2, 3, 8
• Simple conization may be considered for stage IA2 without LVSI if margins are negative and lymph nodes are negative 1, 2

Postoperative Considerations

Immediate Postoperative Management:

• Hospital discharge: Typically day 4-5 6, 8
• Operative time: 420 minutes (laparoscopic approach) 7
• Blood loss: Usually <200 mL 7

Critical Pitfall - Need for Completion Surgery:

Approximately 27% of patients will require completion hysterectomy or adjuvant chemoradiation due to: 5

• Positive margins on final pathology
• Positive lymph nodes (16% of cases) 5
• Unfavorable intraoperative findings (15% require immediate completion hysterectomy) 5

Adjuvant Therapy Indications:

If pathology reveals LVSI, grade 3 disease, positive resection margins, or multiple positive nodes, adjuvant chemoradiation is indicated 1. This significantly impacts fertility preservation goals.

Oncologic Outcomes:

• Recurrence rate: 1-7% depending on tumor size 9, 5
• Patients with tumors >2 cm have threefold higher recurrence risk regardless of surgical radicality 9
• 5-year survival: Comparable to radical hysterectomy in appropriately selected patients 2

Obstetric Outcomes:

Pregnancy Rates:

• Overall clinical pregnancy rate: 53.2% across all approaches 9
• Vaginal radical trachelectomy: 67.5% pregnancy rate (highest among approaches) 9
• Abdominal trachelectomy: 51.5% pregnancy rate 9
• Laparotomy approach: 36% pregnancy rate (lowest) 9
• 21% of pregnancies require ART 9

Live Birth Outcomes:

• Mean live birth rate: 67.8% 9
• Preterm delivery rate: 37.6% 9
• Primary cause of preterm birth: Postoperative cervical length restriction leading to cervical incompetence and ascending infections 9

Long-Term Surveillance:

• Recurrence typically occurs within 0.5-3 years after treatment 4
• Regular follow-up with physical examination and imaging as clinically indicated
• Monitor for vaginal bleeding, discharge, or pelvic pain 4

Special Consideration - Neoadjuvant Chemotherapy:

For stage IB2 disease with tumors 2-4 cm, neoadjuvant chemotherapy followed by fertility-sparing surgery showed 76.6% viable delivery rate among 64 attempted pregnancies, with only 9.4% preterm births 9. This represents an emerging option for extending candidacy.

Key Clinical Pearls:

1. The cerclage is essential to prevent preterm delivery due to cervical incompetence 6
2. Frozen section margin assessment is mandatory during the procedure 6
3. Pelvic lymphadenectomy should be performed first; if positive nodes are found, abandon trachelectomy and proceed with chemoradiation 2, 3
4. Counsel patients preoperatively that nearly 1 in 4 will require completion surgery or radiation, eliminating fertility preservation 5
5. Adenocarcinoma histology and LVSI are common in trachelectomy candidates and do not contraindicate the procedure 5
