It is important to assess clinically relevant outcomes in order to improve care. The availability of such data provides an essential benchmark against which future service change can be assessed. It is critical that interventions are validated against patient outcomes, as cost-effective use of resources is ever more important in healthcare. Our findings also demonstrate that parents and patients with IBD are still relatively poor judges of their own disease activity. Although this is more accurate when they are in remission, the high false-positive rate during active disease indicates that additional clinical parameters must be used to guide treatment decisions. Although self-reporting constitutes an important part of evaluating disease status, we must better understand the factors that inform this personal assessment before abandoning other, more objective, measures of disease activity.

Hepatocellular carcinoma as a second primary cancer in patients with chronic hepatitis C virus infection夽 Dear Editor, Individuals with hepatitis C virus (HCV) infection have 15–20 times the risk of HCC as compared to those without the infection [1]. Screening for HCC with liver ultrasound every 6 months is advocated for patients with chronic HCV infection and cirrhosis or advanced liver fibrosis (stage F3), even after attainment of sustained virological response (SVR) [2,3]. Approximately 7% of HCV-infected patients with nonliver first primary cancers developed HCC as a second primary cancer (SPC) [4]. The goal of the present study was to identify predictors of HCC as a SPC in HCVinfected patients. In this retrospective study, we identified patients with nonliver first primary cancers and chronic HCV infection (positive anti-HCV and detectable HCV RNA in serum) who were seen at our institution from January 2008 through December 2011. This protocol was approved by our Institutional Review Board. HCC was diagnosed by evaluation of liver mass by liver ultrasound (or computerized tomography scan) and/or biopsy [2]. HCV-infected patients with a nonliver first primary cancer who developed HCC as a SPC (cases) were matched 1:1 to those who did not develop HCC (controls) based on cirrhosis status and age (±5 years) at diagnosis of the first primary cancer. SVR was defined as absence of HCV RNA in the serum 24 weeks after discontinuation of HCV therapy [5]. Matched analysis was conducted and p < 0.05 was considered statistically significant. Thirty-two out of 476 (7%) HCV-infected patients with nonliver first primary cancers developed HCC as a SPC during the study period. Most cases had a solid tumour as the first primary cancer (81%). All patients were cirrhotics. Genotype 1 was the predominant HCV genotype (77%). HCC as a SPC was diagnosed as an incidental finding in most of the cases (75%). The most common treatment modalities for the first primary cancers in the cases were surgery (69%) and chemotherapy (34%). The most common chemotherapeutic agents administered were monoclonal antibodies (rituximab, bevacizumab, and trastuzumab) (n = 6); antimetabolites (cytarabine, methotrexate, capecitabine, and 5-fluorouracil) (n = 5); and systemic corticosteroids (n = 5). Most cases received HCV treatment (75%); majority of them did not achieve SVR (88%). When cases and controls were compared, more cases had solid tumours as the first primary cancer (82% vs. 47%), and had a progressive first primary cancer (76% vs. 47%) (Supplementary Table S1). More cases received HCV treatment (71% vs. 41%), mostly with standard (nonpegylated) interferon alpha 2-containing regimens (75% vs. 43%). None of the cases achieved SVR (0% vs. 29%). There were no significant differences between cases and controls with respect to other risk factors for HCC (Supplementary Table S1). This is the first study to evaluate predictors of HCC as a SPC in HCV-infected patients with a nonliver first primary cancer. HCC developed as a SPC mostly in patients who had solid tumours as first primary cancers and in patients whose first primary cancer was progressive. Most of the patients who developed HCC as a SPC had not achieved SVR. A majority of the cases in our series failed to achieve SVR, likely because a high number of patients were treated with standard interferon-containing regimens. SVR rates have improved with the approval of new direct-acting antivirals [5]. Patients eligible for

these new treatments should be identified early and treated to prevent HCC. Our study highlights that screening recommendations for HCC [2] should be followed in HCV-infected patients with nonliver cancers to ensure early detection of HCC as a SPC. In most patients in our study, HCC was diagnosed incidentally; very few patients had HCC detected on routine screening. Increased awareness regarding the importance of screening for HCC is needed among oncologists.
