Treatment of Insomnia in Patients With Breast Cancer

Insomnia, defined as difficulty falling asleep, staying asleep, or waking up too early at least three times a week for at least 3 months, (American Psychiatric Association 2013) is a common disorder both in the general population and in cancer patients, but it is particularly common in breast cancer patients. (Davidson JR, 2002) (Savard J, 2001). Unfortunately, this issue is often not recognized and is not adequately addressed in common clinical practice (Zhou ES, 2017). Emotional distress, stress after surgery, and side effects of cancer treatments, particularly those related to hormone therapy, all contribute to the onset of insomnia, which, in turn, can contribute to a poor quality of life, to greater fatigue in carrying out daily life activities, to worsening physical and emotional discomfort (Kyle SD, 2010) (Bolge SC, 2009) (Sarsour K, 2011).

To date, insomnia in common clinical practice is an often overlooked problem. Patients report that healthcare providers rarely pay attention to sleep disorders and even if they are evaluated, treatment recommendations tend to focus primarily on prescribing medications (Siefert ML, 2014).

Gemmotherapy is a young branch of phytotherapy developed in the second half of the last century. This branch bases its principles on the therapeutic potential of the meristematic tissues of plants and uses products called glycerine macerates (GM) obtained according to the method of cold maceration of meristematic tissues in water, alcohol and glycerol created by Dr. Pol Henry in the last century or according to the Pharmacopoeias.

The use of concentrated GM (C-GM) has spread (Andrianne, 2008 and 2012). These C-MGs are approximately 10 times more concentrated than traditional GMs, and are therefore traditionally used at lower doses (adults: approximately 5-15 gtt/day) than those used for diluted extracts (adults: up to 1 gtt/kg/day ).

Tilia tomentosa, whose fresh buds are used, is traditionally indicated in all cases of insomnia in adults and children. Its action is carried out by inducing sleep and increasing its duration. In phytotherapy it is recommended in neuroses but also as an antispasmodic, in heart palpitations and in spasmophilia. No type of acute or chronic toxicity is known for this C-GM.

In the proposed study we want to evaluate the action of C-GM from Tilia tomentosa, extracted according to the Pharmacopoeias, for the treatment of insomnia in patients with breast cancer on hormone therapy.
