Counselling is very important
Often we are deviating from what
could be considered the ‘Standard
Recommendations’
In essence – experimentation with
the patient taking the risk.
Cervical Carcinoma
Occurs not uncommonly in younger patients [33% < 40 years]
A real increase in adenocarcinomas
An impression of more cases occurring in nulliparous women –
probably due to women delaying pregnancies as compared to
previous times.

Cervical Carcinoma

Severe Dyskaryosis ? Invasion

? Invasion on Colposcopy

Requires some form of biopsy
Stage 1A1 – Squamous Carcinoma
A loop cone excision of the cervix is sufficient treatment
Once all pre-invasive and invasive disease cleared.
Stage 1A1 Adenocarcinoma
Problem with ‘definition’
Now staging as 1A1 is acceptable
Skip lesions can occur : ? Just Pre-invasive
For lesions 3 -5 mm x 7 mm, 141 women – only 1 case of
lymph node disease [0.73%]
Cervical Cancer:
Trachelectomy

Parametrial Tissue
But will surgery be further modified?
Why parametrial tissue which addresses only 2 of 4 planes ?
In tumour <10mm invasion and <2cms diameter – incidence of
parametrial involvement is estimates at 0.6%
Cervical Cancer
Single or 2 stage procedure ?
If single – depending on Frozen Section Histology
Extra-peritoneal or Intra-peritoneal Lymphadenectomy?
If the procedure is about preserving fertility – it seems
logical to prevent intra-peritoneal surgery when an alternative is available.

Pregnancy:
If achieved –
30% miscarriage rate
Assume – Premature delivery
Assume – Operative Delivery

Recurrence Rates
To date the recurrence rates at about 4% are not in excess of that expected
with a radical hysterectomy.
The application of this procedure to large tumours is less frequent now.
How Safe: Trachelectomy?





Case selection very important
Probably as safe as Radical
Procedures
Avoid in Large tumours [>2cms ?]
Avoid in rare/high risk tumours
For nulliparous women only?
ENDOMETRIAL CANCER
Endometrial Cancer
A Rare issue in women where fertility
is a factor.


Histopathology
Imaging
Both of these are paramount in decision
making.
Endometrial Cancer



Histology: Differentiation between Atypical
Hyperplasia and Frank Carcinoma
Remember – when tissue confirms
Atypical Hyperplasia – Frank Malignancy is
found in the Hysterectomy specimen in
40-50% of cases [Cancer 2006,GOG
study]
Most would agree that fertility
preservation should be limited to those
with well differentiated tumours [stage
1A]
Endometrial Cancer
Imaging:
This is important for the ‘staging’
process.
CT/MTI/Ultrasound?
Kinkel et al,Radiology 1999: Metaanalysis
Contrast enhanced MRI best – BUT of
note myometrial invasion detected
correctly in 90% of cases – i.e. 10%
false negative rate.

Endometrial Cancer
In the main – progestagens used as therapy.
Treatment time to regression ranges from 3.5 – 9 months
Recurrence occurs in about 20% of responders
This approach requires careful surveillance – and repeated
endometrial curettage.
Endometrial Cancer

How to manage??
Mirena IUCD
Progestogens:
GnRH analogues
All the above have been used with reasonable success
[responses about 70%].
Tamoxifen can increase the PR, and hence potentially enhance
the efficacy of progestagenic agents

How safe : Endometrial cancer?



Numbers are too small to make any
dogmatic statements.
We can preserve fertility
After single delivery – most
recommend hysterectomy.
Ovarian Cancer





Agreed fertility preservation in all young
patients [?<40 years]- as:
1. Germ cell tumours very chemosensitive
2. Borderline tumours – normally cured
with local excision [ if early stage]
3. If advanced ovarian cancer – then can
always re-operate.
4. May be another condition – eg
Hodgkins !!

7 cases progressed to ‘invasive’ carcinoma
Important to counsel the patient and is this evidence to
support routine pelvic clearance after completion of the
family ??
Ovarian Cancer



Fertility conservation safe for Borderline
tumours.
In invasive tumours – probably best to
restrict fertility preservation surgery to
properly staged, Stage 1 disease.
Following completion of family – pelvic
clearance seems a logical approach to
reduce recurrences, and considering the
limitations of screening such women.
Conclusions



Yes it can be done – but always the
question is :Should it be done?
Need the full Multidisciplinary Team

together. [?Obstetric/Neonatal?]
