PCA3 useful for early diagnosis of prostate cancer
Based on a meta-analysis reported in the Chinese Medical Journal, prostate cancer antigen 3 (PCA3) can be used for the early diagnosis of prostate cancer and to avoid unnecessary biopsies, with a sensitivity of 0.82, a specificity of 0.962, a positive likelihood ratio of 2.39, a negative likelihood ratio of 0.51, and a diagnostic odds ratio of 4.89.
Risk factors for intra-abdominal abscesses in Crohn’s disease
As reported in Digestion, uncontrolled CRP at week 14 of therapy with infliximab (OR=1.36) and early loss of response to infliximab (OR=5.36) are independent risk factors for intra-abdominal abscesses in patients with Crohns disease.
CTC count predicts survival in mBC
As reported in The Lancet Oncology, circulating tumor cell (CTC) quantification in patients (20 studies; n = 1944) with metastatic breast cancer (mBC) predicts progression-free survival (PFS) and overall survival (OS), especially when coupled with clinicopathologic data. A CTC count ≥ 5/7.5 mL at baseline is associated with decreased PFS (HR = 1.92) and OS (HR = 2.78). An elevated CTC count 3-5 weeks and 6-8 weeks after treatment commences is also associated with decreased PFS (HR = 1.85 and 2.20) and OS (HR = 2.26 and 2.91).
