2. Cervical Cancer
• Sexual dysfunction, loss of fertility*
• Reduced autonomic responses- engorgement,
lubrication and orgasm
• Significant dysparaeunia- due to vaginal shortening and
stenosis
* Bergmark K, Avall-Landqvist E, Dickman PW, Henningsohn L,
Steineck G. Vaginal changes and sexuality in women with a history
of cervical cancer. N Eng J Med 1999;340:1383-1389
• Surgical morbidity-
rarely severe
short-lived or at least stable
treatable
can preserve the ovarian function
3. Radical Trachelectomy
• Initial tendency of small Cx tx to spread laterally into the
parametria and LN, rather than verticaly into uterus/
vagina
• Theoretically possible to resect cervix, parametria and
lymphnodes- preserving uterus, adnexa and vagina
• Like partial nephrectomy/ gastrectomy/ pneumonectomy/
colectomy
• Structures removed-
Majority of the Cx
Part of parametria and paracolpos
Part of uterosacral ligament
1-2 cm of vaginal cuff
Descending cervicovaginal branch of uterine artery is ligated
Permanent encirclage of the cervical stump
Pelvic lymph nodes
• Done abdominally, vaginally, laparoscopically

8. Recurrences
• Unusual recurrences- Vesico-vaginal septum and bladder- needs
very meticuous surgical technique and dissection in proper plane to
prevent dissemination of Tx cells *

recurrence after radical trachelectomy: literature review and implications for the preoperative
selection of patients. Gynecol Oncol 2004;92:1002-1005
• Recurrence in Cx itself- 2 cases
1. Bali- 7 yrs follow up (Recurrence or new primary-?)
2. Bader- 6 mnth FU- detected by Pap smear
• 2 recurrences after Abd trachelectomy- both having bulky Cx (3.8
cm, 5 cm respectively) **
• Role of abd trachelectomy in bulky Cx ?

lesions- then radical trachelectomy

9. Follow up
• Shepherd JH, Mould T, Oram DH. Radical trachelectomy in the early stage carcinoma of the
cervix: outcome as judged by recurrence and fertility rates. BJOG 2001;108(8):882
• Every 3-4 months for 1st 2-3 years
• Then every 6 months for next 2 years
• Then every year
• Colposcopy, cytology and RV examination
• Colposcopy and cytology- frequently unsatisfactory because SCJ is
not often visualized and cytology often meets only squamous cells
• Atypical glandular cells from lower uterine segment is often picked
up by cyto- false +ve results
• Singh et al- 200 smears- most unsatisfactory, 2% atypical gladular
cells (suspicious), only 2 cases true recurrence- abnormality long
before clinical features*

pelvis after trachelectomy. Radiographics 2005;25:41
10. Risk of recurrence
• Size ≥2 cm*
• LVSI*
• Adeno Ca**

12. Obstetric Outcomes (Contd.)
• 1st trimester loss- not higher than that in general
population
• 2nd trimester loss- significantly higher
• Prematurity <32 wk- 15%
• Prematurity <28 wk (↑ morbidity) - <10%
• Majority deliver at term
• Prematurity rate particularly higher after multiple
pregnancy in post-trachelectomy- needs special
consideration before IVF-ET
• Birth weight- Not significantly different as vasculat flow to
uterine artery is preserved (Klemm et al. 2005)
• Abdominal trachelectomy- Obst outcome similar but
chance of ligating uterine arteries higher- risk of IUGR
13. Eitiology of pregnancy loss
• Mechanical - uterus enlarges→ short Cx
cannot offer much support to LUS→ Cx
more likely to dilate prematurely
• Infective- main eitiology →short Cx cannot
form effective protective mucus plug
between vagina and the membranes→
subclinical chorioamnionitis → PPROM
and preterm labour
14. Obstetric Management
• Consultation with specialist in fetal-maternal medicine
• Prophylactic antibiotics and steroid to accelerate fetal
lung maturity- unclear but strongly recommended by
Shepherd*
* Shepherd JH, Mould T, Oram DH. radical trachelectomy in early
stage carcinoma of the cervix: outcome as judjed by recurrence and
fertility rates. Br J Obstet Gynaecol 2001;108:882-885
• Needs USG assessment of neo-cervix (length, diameter,
funneling) regularly**
** Petignat P, Stan C, Megevand E, Dergent D. Pregnancy after
trachelectomy: a high risk condition of preterm delivery. Report of a
case and review of the literature. Gynecol Oncol 2004;94:575-577
• Delivery should be planned at 38-39 weeks by elective
CS due to permanent encerclage
15. Decision for trachelectomy
• Many women, even after choosing such
Sx, decide not to attempt pregnancy
• Uncertain long-term survival results
• There are considerable challenges to
overcome
• Needs pre-op counseling
• In case of recurrence- total radical Sx/ RT
16. Conisation
• 1A1- LEEP, Cold knife/ Laseconisation
• Lymphatic spread extremely low (<1%)- no need
of lymphadenectomy
• Entire cone should be blocked- to prepare
adequate number of sections
• Needs careful colposcopic exam of vagina- as
most recurrences occur from this area
• 5-year survival with optimal care >95%*

18. Management of Stage IA2
• May be individualized using non-FIGO
information to stratify the patients as per H/P
features
LVSI (presence/ Absence)
Degree of differentiation
Type of Tx (Adeno-/ Squamous Ca)
Tx volume (higher risk at upper limit of 1A2)
• Low risk- like 1A1
• High risk- conisation + LN dissection
• Radical trachelectomy + LN dissection
19. Ovarian Transposition
• Transposing ovaries out of the planned RT field- if RT is
required
• 1st described ovarian transposition to keep the ovaries
outside the radiation field*
• No case of iatrogenic menopause in that series (4 cases)
* Lemevel A, Bourdin S, Harousseau J, et al. Ovarian transposition by laparoscopy
before radiotherapy in the treatment of Hodgkin's disease. cancer 1998;83:1420

ovarian lig and transposition of the ovaries without
affecting fallopian tubes- positioning ovaries antero-
laterally at the level of ASIS**

procedure. Am J Obstet Gynecol 2003;188:367

(adenoca)- thus incurs a small risk**

Gynecologic Oncology Group (GOG) study. Am J Obstet Gynecol.1992;166:50

of vagina and Cx, ovarian dysgerminoma and sarcoma
• Pregnancy rates in women trying for conception- 15%
(4/27) for clear cell Ca of vagina/ Cx, 80% (8/10) in
ovarian Tx ***

21. Alternatives
• Oocyte retrieval
• IVF and cryopreservation (ART procedure)
• Cryopreservation of unfertilized oocytes- under research- low fertility
rates
• Autologous orthotoptic/ heterotopic transplantation after
cryopreservation- can restore fertility
• Ovarian tissue can tolerate ischaemia for at least 3 hours
• Success depends on post-grafting ischaemia time after effective
revascularization techniques
• Ethics Committee of ASRM- the physician should inform
the cancer survivors of the alternatives before initiation
of therapy*
