“…146 Controversy remains with regard to whether the observed higher incidences indicate additional risk due to TNF treatment, or whether they are in line with the increased risk of lymphoma observed in RA patients with high inflammatory activity. [147][148][149][150][151] In general, the incidence of other types of malignancies in TNF inhibitor-treated patients was found to be similar to, or lower than that observed in the general population 146,152,153 and other RA populations.…”

“…In patients with RA, etanercept use for as long as 5 years did not seem to be associated with an increase in the incidence of SCC. 20 Adverse events of interest that occurred in the study included 1 occurrence of B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma, 1 occurrence of lymphocyte predominance type Hodgkin's disease, and 2 occurrences of worsening of congestive heart failure. There were no reports of demyelination, tuberculosis, or opportunistic infection.…”

“…Other studies based on retrospective analysis of clinical trials of etanercept and post marketing surveillance databases have supported these findings, showing a comparable incidence of SCC in etanercept-treated patients and in the general population. 135 Moreover, experimental studies in animal models showed that the inhibition of TNF does not promote skin carcinogenesis, but, instead, may impede tumorigenesis and have a protective action. 124,136,137 In a large US cohort of 15,789 patients with RA, compared with 3639 patients with osteoarthritis, a small but significant increased hazard (hazard ratio [HR],1.19) of developing NMSC was noted in RA patients compared with those with osteoarthritis, suggesting that the underlying disease itself and the degree of associated inflammation may predispose to skin cancer.…”
