Combined Systemic and Hepatic Artery Infusion Pump Chemo-Therapy as a Liver-Directed Therapy for Colorectal Liver Metastasis-Review of Literature and Case Discussion.

Colorectal cancer (CRC) is the third most prevalent malignancy and the second most common cause of death in the US. Liver is the most common site of colorectal metastases. About 13% of patients with colorectal cancer have liver metastasis on initial presentation and 50% develop them during the disease course. Although systemic chemotherapy and immunotherapy are the mainstay treatment for patients with metastatic disease, for selected patients with predominant liver metastasis, liver-directed approaches may provide prolonged disease control when combined with systemic treatments. Hepatic artery infusion pump (HAIP) chemotherapy is an approach which allows direct infusion of chemotherapeutic into the liver and is especially useful in the setting of multifocal liver metastases. When combined with systemic chemotherapy, HAIP improves the response rate, provides more durable disease control, and in some patients leads to successful resection. To ensure safety, use of HAIP requires multidisciplinary collaboration between interventional radiologists, medical oncologists, hepatobiliary surgeons and treatment nurses. Here, we review the benefits and potential risks with this approach and provide our single institution experience on two CRC patients successfully treated with HAIP in combination with systemic chemotherapy. We provide our recommendations in adopting this technique in the current era for patient with colorectal liver metastases.

Physician scores vs patient self-report of joint and skin manifestations in psoriatic arthritis.

OBJECTIVE: We aimed to determine the degree of agreement between patient self-report and physician assessment of joint disease activity and damage and degree of skin disease. METHODS: Patients were followed up in the PsA clinic for homunculus for tender joints, swollen joints, deformed joints and problematic joints, as well as the severity of their psoriasis. A rheumatologist documented tender joints, swollen joints and damaged joints as well as psoriasis area and severity index score. The scores were compared using the concordance correlation coefficient and Bland-Altman plots were constructed. RESULTS: One hundred and forty outpatients participated in the study (60 females and 80 males) with a mean age of 52.8 years. Their mean age at onset of psoriasis was 27.4 years and at PsA onset was 36.9 years. The average duration of psoriasis at the time of the study was 25.3 years and of PsA was 16.2 years. The correlation between patient and physician scores was poor for tender and swollen joints, although it was better for deformed joints and psoriasis area and severity index score but still did not reach a level of good agreement. CONCLUSION: PsA patient's self-report has a poor correlation with physician assessment. Thus patient self-reported data are insufficient to accurately monitor PsA disease activity when compared with a physician's joint examination and skin score. Expert physical examination should remain the gold standard for the assessment of actively inflamed joint and skin disease in patients with PsA in both clinical trials and observational cohort studies.
