abstract = {The APROVE study is a prospective one-arm phase-II-study
investigating the safety and treatment tolerability of
postoperative proton beam therapy in women with uterine
cervical or endometrial cancer. In this analysis, we report
the primary study endpoint of safety and treatment
tolerability as well as toxicity rates and progression-free
survival (PFS).25 patients were treated with postoperative
proton beam therapy with a total dose of 45-50.4 Gy (RBE) in
5-6 × 1.8 Gy (RBE) weekly using active raster-scanning
intensity-modulated proton beam therapy (IMPT). Sequential
or simultaneous Platinum-based chemotherapy was administered
if indicated. The primary endpoint was defined as the lack
of any acute ≥ grade 3 gastrointestinal (GI) or urogenital
(GU) toxicity according to the Common Terminology Criteria
for Adverse Events v 4.0 or premature treatment abortion.
Secondary endpoints were clinical symptoms and toxicity,
quality of life and PFS.All patients completed IMPT
according to the protocol, with a median treatment duration
of 43 days (range: 33-51 days). No patient developed GI or
GU toxicity ≥ grade 3, the treatment tolerability rate was
$100\%.$ Therefore, the null hypothesis H0: Tolerability
Rate ≤ $80\%$ could be rejected in favor of the
alternative hypothesis H1: Tolerability rate $>80\%$ using
an exact binomial test with a one-sided significance level
of α = $10\%$ (one-sided p-value p=0.0059). The median
follow-up time after the end of IMPT was 25.1 months (range:
20.2 - 50.3 months). 18 of 25 $(75\%)$ patients completed
the study follow-up of 24 months. 7 patients had progressive
disease. Kaplan-Meier-estimated mean PFS was 39.9 months
$(95\%-CI$ 33.37 months; 46.5 months).Postoperative IMPT is
a safe treatment option for cervical and endometrial cancer
patients with only low-grade acute and late toxicities.
Larger randomized trials are necessary to further assess the
potential of IMPT and improve patient selection.},
