Prognostic factors in patients with advanced hepatocellular carcinoma treated with sorafenib.

BACKGROUND: Sorafenib is the new reference standard for patients with advanced hepatocellular carcinoma (HCC). AIM: To identify prognostic factors in sorafenib-treated HCC patients and to evaluate outcomes with respect to liver function. METHODS: In this retrospective study, 148 HCC patients received sorafenib 400 mg b.d. across 11 Austrian institutions. Seventy-eight HCC patients who received best supportive care (BSC) in the pre-sorafenib era served as a control. RESULTS: In sorafenib-treated patients, low baseline α-fetoprotein, low Child-Pugh (CP) score, compensated cirrhosis, and low baseline aspartate aminotransferase (AST) were associated with significantly longer overall survival (OS) on univariate analysis. CP score and baseline AST remained independent prognostic factors on multivariate analysis. In patients with Barcelona Clinic liver Cancer (BCLC) stage B or C HCC (sorafenib: n = 139; BSC: n = 39), CP-A patients had a median OS of 11.3 (sorafenib [n = 76]) vs. 6.4 (BSC [n = 17]) months (P = 0.010), and CP-B patients had a median OS of 5.5 (sorafenib [n = 55]) vs. 1.9 (BSC [n = 22]) months (P = 0.021). In the sorafenib group, median OS according to baseline AST was 11.8 (<100 U/L [n = 58]) vs. 3.9 (≥100 U/L [n = 15]) months for CP-A patients (P = 0.127), and 6.5 (<100 U/L [n = 33]) vs. 2.1 (≥100 U/L [n = 21]) months for CP-B patients (P = 0.011). There was no survival difference between sorafenib and BSC in patients with BCLC stage D HCC (1.5 vs. 1.4 months; P = 0.116). CONCLUSIONS: Sorafenib was associated with improved survival in both CP-A and CP-B patients. In CP-B patients, baseline AST may be helpful in determining which patients are most likely to benefit from sorafenib.

'Blind' antibiotic treatment targeting Chlamydia is not effective in patients with MALT lymphoma of the ocular adnexa.

BACKGROUND: Recent results have implicated Chlamydia, especially Chlamydia psittaci, in the development of ocular adnexal lymphoma in the large majority of patients. We present our experience with ex-juvantibus antibiotic treatment in patients diagnosed with MALT lymphoma of the ocular adnexa. PATIENTS AND METHODS: A retrospective analysis identified a total of 11 patients (six female, five male) with MALT-lymphoma of the ocular adnexa who were given doxycyclin 200 mg p.o. daily over 3 weeks. Patients were tested also for autoimmune conditions, Helicobacter status and hepatitis along with assessment of MALT-lymphoma specific genetic changes. RESULTS: After a median follow-up of 9 months, none of the patients responded to 'blind' antibiotic treatment with doxycyclin. Only one patient with bilateral conjunctival lymphoma related a short lasting subjective improvement, but was referred to alternative therapy due to progression and worsening symptoms after 6 months. CONCLUSIONS: In this uncontrolled series, no effect of 'blind' antibiotic treatment with doxycyclin could be found in our patients with MALT lymphoma of the ocular adnexa. These results are in contrast to other series and suggest a potential geographic difference in the role of Chlamydia in ocular adnexal lymphoma. Thus, antibiotic therapy without prior testing for Chlamydia should be discouraged.
