Vaginal Radical Trachelectomy (VRT)
11
VRT
  • The vaginal mucosa is injected to separate the
    planes of dissection.

Sonoda Y, Abu-Rustum NR.Gynecol Oncol. 2007
Feb104(2 Suppl 1)50-5.
12
VRT
  • The vaginal mucosa is incised. The outer layer is
    incised completely only anteriorly and
    posteriorly. The lateral incisions are shallow.

13
VRT
  • The vaginal mucosa is folded over the cervix.

14
VRT
  • The posterior cul de sac is entered.

15
VRT
  • The pararectal space is opened to isolate the
    uterosacral ligaments.

16
VRT
  • The uterosacral ligament is divided.

17
VRT
  • The vesicouterine space is developed with sharp
    dissection.

18
VRT
  • The paravesical space is opened.

19
VRT
  • The knee of the ureter can be palpated in the
    bladder pillar.

20
VRT
  • The bladder pillar can be divided to allow for
    more descensus.

21
VRT
  • Two clamps are used to divide the parametrium
    once the ureter is assured to be away.

22
VRT
  • The cervicouterine branch of the uterine artery
    is divided.

23
VRT
  • Amputating the cervix.

24
VRT
  • A cerclage is placed to help support the cervix.

25
VRT
  • Final reconstruction of vagina to residual
    cervix.

29
Abdominal Radical Trachelectomy (ART)
  • The uterus is manipulated by clamps on the round
    ligaments avoiding the utero-ovarian pedicles.

30
ART
  • The uterine vessels are then ligated and divided.
  • The parametria and paracolpos with uterine
    vessels are mobilized medially with the specimen.
  • A complete ureterolysis is performed.
  • The posterior cul de sac peritoneum is incised
    and the uterosacral ligament divided.
  • The parametria and paracolpos are divided.

31
ART
  • After completely separating the parametria,
    ligating the uterine vessels at their origins and
    completing the ureterolysis, an anterior colotomy
    is performed facilitated by a vaginal cylinder.

32
ART
  • A Wertheim clamp can be used to determine the
    vaginal resection margin.

33
ART
  • Clamps are placed at the level of the internal
    os.
  • Using a knife, the radical trachelectomy is
    completed by separating the fundus from the
    isthmus or upper endocervix at approximately 5 mm
    below the level of the internal os.

34
ART
  • Endometrial and upper endocervical curettage as
    well as a shave margin on the remaining tissue is
    sent for frozen-section.
  • Frozen section is obtained on the endocervical
    margin.
  • Frozen section is obtained circumferentially on
    the vaginal cuff.

35
ART
  • A permanent cerclage with 0 Ethibond is placed
    and the knot tied posteriorly.

36
ART
  • Reconstruction of the uterine corpus to upper
    vagina after the cerclage is placed.

37
ART
  • The uterine fundus is reattached to the vaginal
    apex with 6 to 8 interrupted 2-0 absorbable
    sutures.

38
ART
  • The reconstructed fundus with remaining blood
    supply from the intact utero-ovarian
    ligamentsuterine serosa without evidence of
    fundal ischemia.

Robotic Radical Trachelectomy (RRT)

    Bilateral Pelvic Lymphadenectomy in Early-stage

    .
  • Burnett A, Robotic radical trachelectomy and
    pelvic lymphadenectomy in early cervical cancer,
    Gynecol. Oncol. 112 (2009), p. S8.
  • Six cases reported

40
Intraoperative Margin Assessment
  • The peripheral soft tissue including the
    parametria is inked green while the LUS/EC
    margins are inked blue.
  • In some cases, the tumor will appear in the
    frozen section at lt 5 mm from the margin.
  • In these cases, the LUS margin is revised.

41
Intraoperative Margin Assessment
  • The margin was reported as negative in 123,
    suspicious in 3 and positive in 6 cases.
  • It was revised in 16 cases (6 positive, 2
    suspicious and 8 negative but lt 5 mm).
  • Final margin assessment agreed with the FS
    diagnosis in 130 (98.5).
  • No false negative intraoperative assessment was
    found.

RH vs VRT/ART
  • No statistical differences between the two groups
  • median number of lymph nodes removed (26 vs 28)
  • node positive rate (15 vs 8)
  • The 5-year recurrence free survival rate
  • 96 (for the RT group compared to
  • 86 for the RH group
  • P  NS

ART
  • Median time in the operating room was 298 min
    (range, 180425).
  • Median estimated blood loss was 250 ml (range,
    50700).
  • Median hospital stay was 4 days (range, 36).
  • No recurrence.

45
Cytologic Findings after RT
  • An endometrial component was identified in 131 of
    the cases (59).
  • Twenty-eight cases were diagnosed as abnormal.
  • The biopsies confirmed the presence of a lesion
    in only 4 of 25 biopsies
  • 3 low-grade squamous intraepithelial lesions
  • 1 adenosquamous carcinoma
  • All cases diagnosed as atypical glandular cells
    represented tubal metaplasia, lower uterine
    segment glandular cells, or endometrial stromal
    cells.

Cytologic Findings after RT
  • Lower uterine segment glandular cells.
  • Endometrial stromal cells.
  • Tubal metaplasia.

Fertility Preserving Surgery
  • Over 900 cases have been performed.
  • Most have been carried out vaginally (radical
    vaginal trachelectomy and laparoscopic pelvic
    node dissection).
  • A smaller number have been performed abdominally.
  • Over 300 pregnancies reported with 196 live
    births.
  • 10 significant prematurity rate with birth prior
    to 32 weeks.
  • 31 recurrences (4), and 16 deaths (2).

Phase II trial of neoadjuvant paclitaxel and
cisplatin in uterine cervical cancer
  • Stage IB2 to IIB
  • Paclitaxel 60 mg/m2 followed by cisplatin 60
    mg/m2 every 10 days and for three courses.
  • 43 patients were enrolled in this study and all
    of them were given an operation.
  • Hematologic toxicity was seen in 17 patients. But
    most of them were anemia and there was no grade 3
    or 4.
  • Grade 1 neurotoxicities developed in 29 patients
    and all of them were peripheral neurotoxicity.

ART in First 10 Patients
  • Ten patients underwent radical abdominal
    trachelectomy.
  • Two patients achieved pregnancy
  • 1 twin delivery
  • 1 patient had 2 pregnancies.
  • Two patients experienced cervical stenosis with
    regular menses and the same 2 patients passed
    their abdominal cerclage vaginally.
  • To date there have been no cancer recurrences.

51
ART in First 10 Patients
  • The experience was based on ten cases performed
    at Massachusetts General Hospital.
  • Surgery was essentially identical to that of
    radical hysterectomy with the exception of
    re-anastomosis of the uterine fundus to the
    vagina and placement of cerclage.
  • Radical abdominal trachelectomy can be
    successfully performed by any gynecologic
    oncologist who is trained in radical pelvic
    surgery.

52
Radical Trachelectomy
  • A viable option for nulliparous women who desires
    future childbearing.
  • Ideal candidates are those with stage Ib1
    cervical cancer with no metastasis.
  • Abdominal trachelectomy is easy to be adopted by
    experienced gynecologic oncologist.
  • Over 200 live births reported.
  • Compatible recurrence and death rate as radical
    hysterectomy.
