Clinical assessment, laboratory investigations, transvaginal ultrasound, and subsequent computed tomography (CT) imaging of the abdomen and pelvis were performed to establish the diagnosis. CT imaging revealed a characteristic oval fat-density lesion with surrounding inflammation adjacent to the sigmoid colon, consistent with epiploic appendagitis. Other differential diagnoses, including ovarian pathology and diverticulitis, were excluded. The patient was managed conservatively with analgesia, and the abemaciclib was temporarily discontinued and restarted at a lower dose, leading to symptom resolution. This case underscores the importance of considering epiploic appendagitis in the differential diagnosis of acute abdominal pain, particularly in patients on targeted therapies like abemaciclib, which are known to have gastrointestinal side effects. Timely and accurate diagnosis via imaging avoided unnecessary surgical intervention.</p><p><strong>Conclusion: </strong>This case is the first of its kind to propose a novel association between the use of targeted therapies such as abemaciclib and the development of inflammatory conditions such as epiploic appendagitis.

It is frequently applied for drugs with characteristics like PK variability or narrow therapeutic window, among others, to ensure optimal therapeutic outcome while minimizing adverse effects. Many molecular targeted agents (MTAs) for malignancies, especially tyrosine kinase inhibitors, exhibit significant variability in exposure, and yet are still dosed with a \"one-size-fits-all\" approach.

Yet, current dosing approaches do not fully account for the complex pathophysiological characteristics of the patients. In this regard, the effect of sex on anticancer chemotherapeutic drugs' disposition is still underexplored. In this article, we review sex differences in chemotherapeutic drug pharmacokinetics; we suggest a novel approach that integrates sex into the traditional a priori body surface area (BSA) dosing selection model, and finally, we provide an overview of the potential benefits of a broader use of therapeutic drug monitoring (TDM) in oncology.</p><p><strong>Summary: </strong>To date, anticancer chemotherapeutic drug dosing is most often determined by BSA, a method widely used for its ease of practice, despite criticism for not accounting for individual factors, notably sex.

At equivalent doses, females tend to display higher circulating exposure and more organ toxicities, which has been formally demonstrated at present for about 20% of chemotherapeutic drugs.

The homologous recombination (HR) pathway is crucial for repairing DNA double-strand breaks (DSBs). Rad51 plays a central role in HR, facilitating the search for homology and promoting DNA strand exchange between homologous DNA molecules. Rad51 is overexpressed in numerous types of cancer cells. B02, a specific small molecule inhibitor of Rad51, inhibits the DNA strand exchange activity of Rad51. Previous studies have indicated that B02 disrupted Rad51 foci formation in response to DNA damage and inhibited DSBs repair in human cells and sensitized them to chemotherapeutic drugs in vitro and in vivo. However, the potential therapeutic effects of combining osimertinib with a Rad51 inhibitor are not well understood.
