RESUMEN
We report a case of pulmonary tumor embolism due to hepatocellular carcinoma (HCC). A woman in her 60s was treated with sorafenib 800 mg daily for HCC with lymph node metastasis. Approximately 50 days after taking sorafenib, she experienced dyspnea and was admitted to the hospital on account of hypoxia. Although her oxygen saturation levels deteriorated, we could find no obvious cause for the hypoxia; despite artificial respiration and oxygenation, she died of respiratory failure on the fourth day of admission. Tissue samples revealed that the HCC cells had infiltrated her lung arterioles; therefore, we concluded that multiple tumor microembolisms from the HCC to the lungs had caused death via respiratory failure. Cases of hypoxia caused by multiple invisible embolisms from HCCs are rarely reported. We believe that infiltration into the lymphatic system may have been related to the development of pulmonary tumor microembolisms.

We report a case of double liver cancer in an elderly woman with chronic hepatitis C. The patient was diagnosed with two liver tumors when she was in her 70s, and she underwent hepatectomy for the same. Histopathological examination determined that the two tumors were distinct. One was a well-to-moderately differentiated hepatocellular carcinoma (HCC) and the other was a combined hepatocellular carcinoma and mucinous cholangiocarcinoma (ChC). The HCC component was positive for cytokeratin 19, and it infiltrated into the portal vein and artery and the gall bladder. The ChC component was positive for hepatocyte paraffin 1 (HepPar1) staining and infiltrated into the bile duct. There has been no cancer recurrence at 6 months after surgery. Double cancer of the liver with these histological types is extremely rare and interesting, given the origin and differentiation of liver cancer.

AIM: The onset of depression symptoms during pegylated interferon α plus ribavirin (PEG-IFN/RBV) combination therapy has led to treatment discontinuation in some cases. In the present study, we conducted a questionnaire survey during treatment to determine whether natural human interferon ß plus ribavirin (IFNß/RBV) therapy is associated with a lower incidence of depression symptom onset compared with PEG-IFN/RBV therapy. METHODS: Seventy-seven patients with chronic hepatitis C received PEG-IFN/RBV (PR) or IFNß/RBV (FR) therapy. A questionnaire survey was administered at the start of treatment, and at 4 and 12 weeks, using the Beck Depression Inventory II (BDI-II) and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: BDI-II scores in the PR group increased at 4 and 12 weeks, but remained unchanged in the FR group. At 12 weeks, the mean BDI-II score and incidence of abnormalities with a BDI-II score of ≥14 were significantly lower in the FR group than in the PR group. BDI-II scores during IFNß/RBV therapy in 11 patients currently using antidepressants remained unchanged up to 12 weeks. None of these 11 patients required addition or dose increases of antidepressants, and there was no evidence of worsened depression symptoms. Nine PR patients had BDI-II scores of ≥14 and PSQI scores of ≥11 at 12 weeks. CONCLUSIONS: IFNß/RBV therapy was associated with a lower incidence of depression symptom onset during treatment. In patients already diagnosed with depression, there was no evidence that IFNß/RBV therapy caused any worsening of symptoms, indicating that IFNß/RBV therapy is safe for patients with depression.
RESUMEN
BACKGROUND/AIMS: Radiofrequency ablation therapy (RFA) has become widely used against hepatocellular carcinoma (HCC), mainly because of its ease of use, lower level of invasiveness, and high level of effectiveness. To compare the efficacy and safety of RFA with surgery, we retrospectively investigated relevant patient clinical data. METHODOLOGY: The patients with a single HCC (3 cm > or =, Child-Pugh A or B) who were treated with RFA (RFA-group: n=105) or surgery (Surgery-group: n=59) from January 2000 to June 2007 were enrolled. RESULTS: The ratio of patients classified as Child-Pugh B was greater in RFA-group (24.8% vs. 8.5%, P=0.011), though the sizes of the tumors were not significantly different. There were no significant differences for survival rates or disease free survival rates after 3- and 5-years (RFA-group vs. Surgery-group; survival: 87.8 and 59.3% vs. 91.4 and 59.4%, disease free survival: 58.7 and 24.6% vs. 64.3 and 22.4%, respectively). As for complications, in RFA-group there was no severe complication while there was 1 case of postoperative hepatic failure death and 2 with a postoperative abscess in Surgery-group. CONCLUSIONS: In the present study, patients with a single HCC smaller than 3cm who underwent RFA had a lower frequency of severe complications, thus the efficacy of RFA was thought to be equal to a surgical procedure.
