Purpose: To report a case of a 73-year-old man who presented with decreased visual acuity due to bilateral macular edema after paclitaxel administration for prostate cancer.
Methods: The ophthalmic evaluation consisted of medical and ocular history, Best Corrected Visual Acuity, slit-lamp biomicroscopy and Spectral-domain optical coherence tomography / Fluorescein Angiography.
Results: Optical Coherence Tomography and Fluorescein Angiography revealed silent cystoid macular edema. After consulting with the oncologist, the cessation of paclitaxel therapy was decided. The patient presented a gradual but steady resumption of the retinal edema, with complete restoration of normal retinal morphology and function within two months. The pathogenesis of the silent Cystoid Macular Edema (CME) is still unclear. Based on our case and a critical review of the previous observations and published data, we propose that the underlying cause of Taxane induced CME is the functional failure of Aquaporin mediated water transport at the level of retinal Intermediate and Deep capillary plexuses, and at lesser extent at the level of the Retinal Pigment Epithelium.
Conclusion: Taxane induced silent CME should be attributed to the action of Taxanes on the microtubule guided aquaporin vesicles transport to the cell membrane. In our case of Taxane induced silent CME, withdrawal of the taxane was enough for complete recovery, and no additional treatment was needed.

Advanced ovarian cancer often presents with multiple lesions exhibiting varying responses to chemotherapy, highlighting the critical influence of the tumor microenvironment (TME). This study investigates the phenomenon of chemotherapeutic hormesis, wherein low doses of chemotherapeutic agents, such as cisplatin (CDDP) and paclitaxel (PTX), paradoxically stimulate rather than inhibit cancer cell proliferation. Our findings indicate that NOS3 ovarian cancer cells, particularly drug-resistant variants, exhibit enhanced proliferation when exposed to low concentrations of these drugs.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by the absence of progesterone and estrogen receptors and low (or absent) HER2 expression. TNBC accounts for 15-20% of all breast cancers. It is associated with younger age, a higher mutational burden, and an increased risk of recurrence and mortality.

Docetaxel is a chemotherapeutic agent commonly used against breast cancer, nonsmall cell lung cancer, gastric, prostate, head and neck cancer. Docetaxel- or taxane-induced interstitial lung disease (ILD) remains a relatively rare reported adverse event. Although rare, this complication remains an important event to identify and it carries a high mortality.

Background: Systemic chemotherapy constitutes an indispensable component of breast cancer (BC) management, where therapeutic drug combinations such as anthracyclines, platinum compounds, and taxanes form the cornerstone of standard treatment protocols. Although DNA repair genes are pivotal in cancer susceptibility, their specific roles in mediating acute or chronic toxicity outcomes induced by chemotherapy remain undetermined. Consequently, this study was planned to elucidate the impact of polymorphisms in base excision repair (BER) genes, including XRCC1, XRCC2, XRCC3, APE1, and hOGG1, on treatment response and toxicity outcomes in BC patients undergoing paclitaxel and doxorubicin-based chemotherapy within an Indian population.
