New Horizons for Patients with Endometrial Cancer

September is Uterine Cancer Awareness Month. Raising awareness is very close to the MVisionaries since uterine cancer is the fourth most common cancer for women. It is estimated that 66,570 people in the United States alone will be diagnosed with uterine cancer this year. 90% of uterine cancers are endometrioid adenocarcinoma (or endometrial cancer).

With this in mind, doctors and scientists are working very hard to bring innovative treatment solutions and ideas to uterine cancer. The University Hospital Cologne has been at the forefront of innovation for radiotherapy. Director of University Hospital Cologne, Prof. Dr. Simone Marnitz, researches radiotherapy, brachytherapy, chemotherapy, and gynaecological cancer.

Dr. Marnitz provides in depth insight into the state of endometrial cancer

As stated by Dr. Marnitz, the classic classification into type I (estrogen-dependent) and type II (estrogen-independent) as well as clinical factors (age, myometrium infiltration, grading, tumor size, lymphovascular space involvement) do not adequately reflect the biology of the disease and the prognosis of the individual patient.

We understood that the inadequate patient selection for the large randomized studies on this very clinical basis led to more or less inconclusive results due to a lack of better knowledge and therefore offered no clear evidence for our clinical action [1-3].

The big questions with endometrial cancer – who needs adjuvant radiotherapy and which ones, who benefits from chemotherapy, which patients need chemo-radiation, – will be decided by genomics. Therefore, over- and under treatment can be avoided [4, 5].

At first glance, the following new ones have become established:

  • the presence of the P53 mutation is associated with a clearly unfavorable prognosis,
  • the presence of the POLE mutation with a favorable prognosis, even with locally advanced findings, is associated with a very good clinical outcome,
  • Intermediate courses are described for an unspecified molecular profile (NSMP) and for microsatellite instability (MSI) [6] .

The insights into individual tumor genomics triggered a revolution in oncological therapy decisions [7]. With the new European Guideline we provide a new classification for prognosis, prediction and treatment decision [8]. Now we can offer individual treatment decisions and avoid unnecessary toxicity from chemotherapy and radiation for a substantial number of endometrial cancer patients and escalate adjuvant treatment in a small group of patients with unfavourable genomic characteristics. Clinical trials are on the way to validate the new classification system [9].

Guideline-Compliant Female Pelvis Model 

We are proud to provide the only guideline-compliant female pelvis model for various gynaecological cancers, including endometrial cancer. We have a standard and advanced model, targeting 16 OARs. Both follow multiple consensus guidelines, including ESTRO and RTOG.
