Adjuvant external beam radiotherapy in the treatment of endometrial cancer (MRC ASTEC and NCIC CTG EN.5 randomised trials): pooled trial results, systematic review, and meta-analysis

Summary

Background

Early endometrial cancer with low-risk pathological features can be successfully treated by surgery alone. External beam radiotherapy added to surgery has been investigated in several small trials, which have mainly included women at intermediate risk of recurrence. In these trials, postoperative radiotherapy has been shown to reduce the risk of isolated local recurrence but there is no evidence that it improves recurrence-free or overall survival. We report the findings from the ASTEC and EN.5 trials, which investigated adjuvant external beam radiotherapy in women with early-stage disease and pathological features suggestive of intermediate or high risk of recurrence and death from endometrial cancer.

Methods

Between July, 1996, and March, 2005, 905 (789 ASTEC, 116 EN.5) women with intermediate-risk or high-risk early-stage disease from 112 centres in seven countries (UK, Canada, Poland, Norway, New Zealand, Australia, USA) were randomly assigned after surgery to observation (453) or to external beam radiotherapy (452). A target dose of 40—46 Gy in 20—25 daily fractions to the pelvis, treating five times a week, was specified. Primary outcome measure was overall survival, and all analyses were by intention to treat. These trials were registered ISRCTN 16571884 (ASTEC) and NCT 00002807 (EN.5).

Para-aortic lymphadenectomy in endometrial cancer

Para-aortic lymphadenectomy in endometrial cancer

We were not surprised that the results of the retrospective cohort analysis of SEPAL1 differed from those of two randomised controlled trials.2, 3 With a hazard ratio for overall survival of 1·16 (favouring no lymphadenectomy) in ASTEC,2 it is extremely unlikely that conclusions would change with long-term follow-up because there would have to be a large, late effect which is not suggested by SEPAL. Lymphadenectomy significantly increases moderate and severe morbidity, particularly lymphoedema, and removing more lymph nodes might not be better (figure).

Lack of information about methods makes the results impossible to interpret, particularly patient selection and surgery details (operation length, blood loss, postoperative hospital stay, and related deaths). The median age of 56 years suggests substantial selection (median age was 63 years in ASTEC). Data were gathered over 18 years and information about the distribution of patients in each group across time and any time effect on survival is important. Bias due to differences between the hospitals cannot be excluded, with differing adjuvant protocols and almost double the number of pelvic nodes removed in some hospitals compared with others.

In women at intermediate or high risk of recurrence, the substantial difference in adjuvant chemotherapy received (77% vs 45%) is important. Chemotherapy reduces distal metastases,4 potentially improving survival and the effect of para-aortic lymphadenectomy. The benefit in high-risk patients receiving chemotherapy is only just significant. Since type of lymphadenectomy and adjuvant treatment were independent risk factors for overall survival, there are strong statistical arguments for sensitivity analyses excluding those receiving adjuvant treatment.

Aortic lymphadenectomy was not assessed in either randomised trial and the results of this observational study do not invalidate the conclusions of these trials nor provide conclusive evidence of a real treatment effect.

Lymphadenectomy in endometrial cancer

Lymphadenectomy in endometrial cancer

The Lancet, Volume 373, Issue 9670, Pages 1169 - 1170, 4 April 2009 <Previous Article|Next Article>doi:10.1016/S0140-6736(09)60676-0Cite or Link Using DOI

The ASTEC study group1 conclude that a systematic lymphadenectomy in endometrial cancer cannot be recommended as a routine procedure because of lack of benefit in terms of recurrence-free and overall survival. However, there are several reasons why the ASTEC trial did not show improved overall survival with routine lymphadenectomy.

First, the number of lymph nodes resected was insufficient in many patients. Although the median number resected overall was 12, 35% of patients in the lymphadenectomy group had nine or fewer lymph nodes removed. Cragun and colleagues2 showed that removal of more than 11 pelvic nodes had an effect on overall survival. Chan and colleagues3 showed that, in intermediate-risk and high-risk endometrial cancer, patients with more than 10 nodes harvested have an improved outcome.

Second, many patients with low-risk endometrial carcinoma, and hence a low risk of lymph-node involvement, were included (eg, only 41% had stage IC—IIB disease, and only 22% presented with poorly differentiated tumours). The high rate of inclusion of low-risk patients and the low number of lymph nodes removed are the reasons for the low rate of involved lymph nodes seen in the lymphadenectomy group (9%).

Third, the study group did not assess the para-aortic nodes. However, up to 67% of patients with lymph-node metastases have involved para-aortic nodes.4 Fourth, the ASTEC trial was too small to detect an overall survival difference because the expected proportion of isolated pelvic lymph-node recurrences is as low as 2—3% in early endometrial carcinoma.

In conclusion, we believe that there is still an indication to do a comprehensive lymphadenectomy to select patients at high risk of pelvic side wall recurrence. The selection of patients for a lymphadenectomy should be based on myometrial invasion, grade, and diameter of the tumour.5

We declare that we have no conflict of interest.
