Abstract
Background: Uterine leiomyosarcomas (uLMS), although rare (3%-7% of all uterine malignancies), represent an
important share of mortality due to uterine pathology. Surgery is the cornerstone of treatment but the lack of data
from randomized clinical trials makes the function of adjuvant therapy still nebulous. For these reasons, the
treatment of the uLMS is still a challenge in progress.
Case presentation: We report the case of 72-years old woman who underwent several lines of therapy. After
systemic disease progression, was subjected to a genetic test that showed a mutation of CDKN2A. Basing on these
results, the patient started Palbociclib, which is still ongoing.
Conclusion: The choice of drug was based on the presence of the patient’s specific mutation and not on
therapeutic options recommended by guidelines. In this woman, heavily pretreated, Palbociclib showed the stability
of disease at the first re-evaluation with an acceptable safety profile and no signs of cumulative toxicity.

Introduction
Uterine leiomyosarcomas (uLMS), arising from the myometrium,
represent the most common type of uterine sarcoma, with poor
prognosis. Tey account for approximately 3%-7% of all uterine
malignancies [1] and are characterized by an early hematogenous
spread and a high rate of distant metastasis, located especially in lungs,
even in the absence of lymph nodes involvement [2,3].
Metastatic disease diagnosis is ofen delayed and made afer
hysterectomy. Te defnition of a clear therapeutic approach is limited
by the rarity of the disease and, consequently, the lack of randomized
studies. Hysterectomy is currently the therapeutic cornerstone.
Adjuvant radiotherapy seems to have had an advantage in the local
control but not in the OS [4].
Also, the role of systemic therapy is not well defned, although it is
still used for the high tendency to relapse, that it stands around
50%-70% [5].
As in other diseases, the fnal aim of uLMS treatment is to fnd
molecular targets for new potential drugs [6].
Te most frequent mutation found in uLMS are growth factors
over-expression as C-MYC, Bcl-2, K-ras, and Ki-67, and loses in tumor
suppressors as p16, p53, Rb1, ING2 and D14S267 [6]. However,
multiple genetic aberrations and very complex karyotypes make
difcult to identify molecular targets and can facilitate the
refractoriness to subsequently treatment lines.
In this context, where traditional therapies turned out to be
inefective, a new approach resulted in fundamental.
We present the case of a heavily pre-treated metastatic uLMS patient
that, because of previous lines failure and not tolerated side efects,
underwent DNA sequencing, to evaluate a targeted therapy.
Case Presentation
Tis is the case of a 72 years old patient, with a previous non-
oncological history of arterial hypertension, bronchial asthma, and
hypercholesterolemia.
A pelvic mass was shown in December 2008 and she was subjected
to histeroannessectomy.
Histological examination revealed a leiomyosarcoma of the uterine
wall with epithelioid aspects, a maximum diameter of 4.7 cm and a
mitotic index>10/10 HPF. Vascular invasion and metastasis were
present in the right ovary.
From February 2009 to July of the same year, six cycles of
Doxorubicin 50 mg/mq and Ifosfamide 5 g/mq, as adjuvant systemic
therapy, were administered. Ten regular follow-ups were performed.
In October 2012 a CT scan demonstrated multiple pulmonary
metastases and 2 cm lef breast nodular lesion correlated to uLMS.
Terefore, it was started a second line chemotherapy with Gemcitabine
900 mg/mq 1°, 8° and Docetaxel 100 mg/mq 8° q21 with poor
response, so in March 2013 this treatment was stopped, and a new-one
Trabectedin based was started (Trabectedin 1.7 mg/mq q21).
Te CT scan performed in October 2013 showed the stability of all
lesions except one, localized in the apical segment of the LID. Te
