Objectives: Curative hepatectomy and tumor thrombectomy for hepatocellular carcinoma with complicating biliary tumor thrombosis (HCC/BTT) is associated with high surgical morbidity and mortality. This retrospective study evaluated the effectiveness and safety of neoadjuvant transcatheter arterial chemoembolization (TACE) in HCC/BTT patients scheduled for curative resection.

Methods: Thirty consecutive patients with diagnosed HCC/BTT were hospitalized for neoadjuvant TACE and elective curative liver resection (group A; n=20) or curative liver resection alone (group B; n=10). The primary outcome measure was median survival.

Results: Group A had a significantly shorter overall operative time (160±25 versus 190±35 min; p < .01) and duration of inflow control (14.3±3.6 versus 25.1±5.1 min; p < .01) and significantly less intraoperative blood loss (150±35 versus 520±75 ml; p < .01) and transfusion (100±40 versus 375±55 ml; p < .01) as compared to group B. Among patients undergoing both thrombectomy and curative resection, the median survival of group A was significantly longer than that of group B (28.5 [9–54] versus 21.5 [6–39] months; p < .01); among those who received thrombectomy alone, the median survival of group A was also significantly longer than that of group B (12.8 [6–25] versus 4.5 [2–7] months; p < .01).

Conclusions: Neoadjuvant TACE significantly reduced the surgical risk of curative liver resection and significantly prolonged median survival in HCC patients with complicating BTT.

Objectives: Chemotherapy has adverse effects on cognitive performance in women treated for breast cancer, but less is known about the period before chemotherapy. Studies have focused on mean level of performance, yet there is increasing recognition that variability in performance within an individual is also an important behavioral indicator of cognitive functioning and underlying neural integrity. Methods: We examined intraindividual variability (IIV) before chemotherapy and surgery in women diagnosed with breast cancer (n=31), and a healthy control group matched on age and education (n=25). IIV was calculated across trials of a computerized Stroop task, including an examination of the slowest and fastest trials of reaction time (RT) responses. Results: The groups were equivalent on overall accuracy and speed, and participants in both groups were less accurate and slower on incongruent trials compared with congruent trials. However, women with breast cancer became more variable with increased task difficulty relative to healthy controls. Among the slowest RT responses, women with breast cancer were significantly more variable than healthy controls on incongruent trials. This suggests that a specific variability-producing process (e.g., attentional lapses) occurs in task conditions that require executive control (e.g., incongruent trials). Conclusions: Results are consistent with other evidence of executive dysfunction among women treated for breast cancer. These findings highlight the importance of pretreatment assessment and show that variability in performance provides information about cognition that measures of central tendency do not.
