Ibrutinib is an orally available, small-molecule tyrosine kinase inhibitor. Its main purpose is to inhibit Bruton's tyrosine kinase (BTK), an enzyme that is crucial in B cell development. It is FDA approved for the treatment of certain hematological malignancies. Several promising off-target drug effects have led to multiple, mostly preclinical investigations regarding its use in solid tumors. Unfortunately, data on its effectiveness in gynecological malignancies are limited, and (systematic) reviews are missing. The objective of this review was to summarize the existing literature and to analyze the evidence of ibrutinib as a treatment option in gynecological malignancies, including breast cancer. Studies were identified in MEDLINE and EMBASE using a defined search strategy, and preclinical or clinical research projects investigating ibrutinib in connection with these malignancies were considered eligible for inclusion. Our findings showed that preclinical studies generally confirm ibrutinib's efficacy in cell lines and animal models of ovarian, breast, and endometrial cancer. Ibrutinib exerts multiple antineoplastic effects, such as on-target BTK inhibition, off-target kinase inhibition, and immunomodulation by interference with myeloid-derived suppressor cells (MDSCs), programmed death-ligand 1 (PD-L1), and T cell response. These mechanisms were elaborated and discussed in the context of the evidence available. Further research is needed in order to transfer the preclinical results to a broader clinical appliance.

Angiogenesis is essential for tumor growth and metastasis. The main regulators of the process are the signaling cascades of VEGF-, PDGF- and FGF receptors. Inhibition of these pathways holds potential therapeutic benefit not only for cancer patients, but also for the treatment of other diseases. This paper summarizes the experimental and clinical results of studies available so far on the multi-target tyrosine kinase inhibitor nintedanib (BIBF 1120). According to these studies, nintedanib effectively inhibits VEGFR-, PDGFR- and FGFR signalization and thus the proliferation and survival of cell types which highly express these receptors (i.e. endothelial and smooth muscle cells and pericytes). In vitro studies and in vivo xenograft experiments have provided promising results. In the clinical setting, BIBF 1120 seems to be effective and well tolerated in various tumor types, such as lung, prostate, colorectal and hepatocellular carcinoma, as well as in gynecological tumors. The main adverse events are gastrointestinal toxicities and the reversible elevation of liver enzyme levels. Nintedanib might also be combined with paclitaxel, carboplatin, pemetrexed and docetaxel. There are several ongoing clinical trials testing the efficacy of BIBF 1120.

Lafutidine, an antagonist of histamine H2-receptor, has gastroprotective activity associated with activation of capsaicin-mediated sensory nerves. The objective of this study was to investigate the efficacy of lafutidine for the treatment of taxane-induced peripheral neuropathy in patients with gynecological malignancies.. Twenty patients with taxane-induced peripheral neuropathy during the treatment of gynecological malignancy were enrolled in this study. After obtaining their informed consent, lafutidine (20mg per day) was administered orally, the efficacy of which was assessed according to the Patient Neurotoxicity Questionnaire item 1.. Significant, moderate, slight, and no effects were observed in four, five, five, and six patients, respectively. The efficacy including significant and moderate effect was observed in nine (45%) of the 20 patients (95% confidence interval, 25.8%-65.8%). No adverse effects due to lafutidine were observed.. This pilot study supports the relatively high efficacy of lafutidine for the treatment of taxane-induced peripheral neuropathy. Further prospective studies are warranted.
