doxorubicin and paclitaxel, or docetaxel, for invasive ductalbreast cancer [dosages and routes not stated; durations oftreatment to reaction onsets not clearly stated].
Patient 1, a 24-year-old woman, received adjuvantchemotherapy consisting of four cycles of doxorubicin andcyclophosphamide, followed by four cycles of paclitaxel.Following treatment, she reported cognitive delays andmemory problems. Neuropsychological examination wasperformed 1 month after the completion of chemotherapy,after she reported a lack of focus and difficulty findingwords. Her psychiatric history was notable for adjustmentdisorder with mixed anxiety and depressed mood,diagnosed during adjuvant chemotherapy, and insomnia.Cognitive assessment revealed significant attentionaldifficulties; she had problems quickly and efficientlyprocessing stimuli, and her responses were more erraticwhen inter-stimulus intervals slowed. She displayedvariability in her learning and working memory, and herrecognition of a word list was lower than expected. Herimmediate and delayed visual memory was unorganised,and she had very mild dysnomia. Findings were consistentwith her reports of inattention, distractibility and word-finding problems. Her sleep was restored following theintroduction of zolpidem, and she was referred forcognitive rehabilitation. She subsequently receivedmethylphenidate, but discontinued the drug due toassociations with hyperactivity. She was re-evaluated7.5 months after chemotherapy, while undergoingtreatment with tamoxifen (introduced 2 months aftercompletion of chemotherapy). She appeared to bedemonstrating the typical trajectory of improvement incognitive function, although attention and vigilancecontinued to be deficits. Her memory, cognitive flexibilityand word-finding had significantly improved.
Patient 2, a 36-year-old woman, completed four cycles ofdocetaxel [Taxotere] and cyclophosphamide, followed byradiation therapy. She developed left thumb, wrist andforearm pain following a chemotherapy extravasation.Following completion of adjuvant chemotherapy,pregabalin was introduced for hot flashes and mildsensorimotor polyneuropathy. She also reported cognitivedecline and, upon referral, she stated that her thoughtswere "fuzzy" and that she would forget what she was goingto say. Her medical history was notable for cognitivebehavioural therapy during cancer treatment, and insomniapost-treatment. On examination, 3 months aftercompleting chemotherapy, her gait appeared stiff and shedisplayed limited mobility in her nondominant, left hand.Her neuropsychological profile was indicative of deficits inattention, executive functioning and vigilance. She haddifficulty detecting stimuli from non-stimuli, and hermemory for narratives was lower than expected at theimmediate recall and mildly impaired after a half-hourdelay. She also appeared mildly depressed and anxious dueto her cancer and fears of recurrence. She was referred forcognitive rehabilitation. Upon re-evaluation 9 months afterchemotherapy, her neuropsychological profile revealedsome improvements, but she continued to have difficulty incertain areas. She indicated persistent attentionaldifficulties and executive dysfunction, consistent withchemotherapy-related cognitive side effects. She continuedto have difficulties problem-solving and maintainingattention.
