Conservative (non-radical) surgery for stage IB1 cervical cancer

Conservative surgical approaches for small volume FIGO stage IB1 cervical cancer. Updated survival and obstetric outcomes of an expanded cohort

OBJECTIVE

Standard surgical treatment of FIGO stage 1B1 cervical cancer is open radical surgery. However, there is increasing evidence that for small tumours a more conservative approach can minimise fertility consequences without impacting on long term oncologic outcomes. The objective of our study is to present survival and obstetric outcomes following extended follow-up for patients who underwent conservative management of small-volume stage 1B1 disease.

METHODS

All patients with FIGO stage 1B1 cancer and estimated tumour volume of <500 mm3 in a loop biopsy specimen treated in Northern Gynaecological Oncology Centre between December 2000 and December 2021, were included in the study. Clinico-pathological and demographic data were collated alongside detailed follow-up and obstetric outcomes in conjunction with primary care and death register.

RESULTS

117 patients underwent conservative surgery for small volume stage 1B1 disease. 58 (49.5%) underwent fertility sparing conservative management with LLETZ while 59 (50.5%) underwent simple hysterectomy. Overall, 95% (111/117) of the patients underwent bilateral pelvic lymphadenectomy and 1 positive node was identified. There was no death related to cervical cancer and 1 recurrence identified during a median follow up of 8.5 years (1-20). 17 pregnancies have been recorded in patients underwent LLETZ and 17 live babies were born. No second trimester miscarriages were noted and there was one preterm delivery (36 weeks).

CONCLUSION

Non-radical surgery with negative pelvic lymphadenectomy for smallvolume stage 1B1 cervical cancer ensures excellent survival without compromising obstetric outcomes. Should these results be verified by the ongoing prospective studies, radical surgery for these patients may be avoided.

Overview of fertility sparing treatments for cervical cancer

Until the late 1980s, the mainstay of treatment for cervical cancer has been either hysterectomy or radiotherapy. From the mid to late 1990s, surgical treatments have been focussed more on sparing fertility by preserving the corpus of the womb with trachelectomy or even conserving part of the cervical stroma with a cone biopsy. In carefully selected cases, less radical treatment that preserves the uterus has been considered safe. However, these approaches can be associated with specific operative and obstetric complications such as stitch ulceration, cervical stenosis, late miscarriage, and premature labour. Most guidelines agree that the management of such patients should be centralised in a unit with specialist gynaecological oncology, radiology, and histopathology services supported by specialist cancer nurses.
