RESUMO
OBJECTIVE: Focal nodular hyperplasia (FNH) is a benign liver tumor considered to develop under the influence of estrogens. Whether women with known FNH are at higher risk of growth progression and complications during pregnancy is still controversially discussed. The authors investigated the growth pattern of FNH during pregnancy and possible related complications. MATERIALS AND METHODS: Twenty pregnant women with FNH were followed by the authors' center. Before pregnancy, diagnosis of FNH was usually established by contrast-enhanced ultrasound. During pregnancy, monitoring of FNH was performed by conventional ultrasound. Furthermore, a questionnaire was sent to all patients. RESULTS: Patient's age ranged from 24 to 36 years. Mean size of FNH before pregnancy was 58.5 ± 22.7 mm. It did not vary significantly during pregnancy (fourth month of pregnancy: 58.1 ± 23.0 mm; after pregnancy: 55.5 ± 26.8 mm; -8%; n.s.). Only in three patients, growth of FNH by 18 ± 6% was observed, while FNH size remained constant in 7 patients and even declined by -11 ± 6% in 10 patients. There were no FNH-related complications. The questionnaire was sent back by 16 patients (80%). All responding patients took oral contraceptives in the past over a mean 12.4 ± 4.4 years. Previous pregnancies were reported by 38% of patients. FNH-related fears were expressed by 63% of patients, but no FNH-related complications or symptoms during pregnancy were noted. CONCLUSIONS: This study demonstrates that women with FNH are not at risk of significant growth progression or FNH-related complications. Pregnancy should not be discouraged in these patients but careful advice and guidance are necessary.

AIM: To evaluate the treatment effect of percutaneous ethanol injection (PEI) for patients with advanced, non-resectable HCC compared with combination of transarterial chemoembolisation (TACE) and repeated single-session PEI, repeated single-session PEI alone, repeated TACE alone, or best supportive care. METHODS: All patients who received PEI treatment during the study period were included and stratified to one of the following treatment modalities according to physical status and tumor extent: combination of TACE and repeated single-session PEI, repeated single-session PEI alone, repeated TACE alone, or best supportive care. Prognostic value of clinical parameters including Okuda-classification, presence of portal vein thrombosis, presence of ascites, number of tumors, maximum tumor diameter, and serum cholinesterase (CHE), as well as Child-Pugh stage, alpha-fetoprotein (AFP), fever, incidence of complications were assessed and compared between the groups. Survival was determined using Kaplan-Meier and multivariate regression analyses. RESULTS: The 1- and 3-year survival of all patients was 73% and 47%. In the subgroup analyses, the combination of TACE and PEI (1) was associated with a longer survival (1-, 3-, 5-year survival: 90%, 52%, and 43%) compared to PEI treatment alone (2) (1-, 3-, 5-year survival: 65%, 50%, and 37%). Secondary PEI after initial stratification to TACE (3) yielded comparable results (1-, 3-, 5-year survival: 91%, 40%, and 30%) while PEI after stratification to best supportive care (4) was associated with decreased survival (1-, 3-, 5-year survival: 50%, 23%, 12%). Apart from the chosen treatment modalities, predictors for better survival were tumor number (n < 5), tumor size (< 5 cm), no ascites before PEI, and stable serum cholinesterase after PEI (P < 0.05). The mortality within 2 wk after PEI was 2.8% (n = 3). There were 24 (8.9%) major complications after PEI including segmental liver infarction, focal liver necrosis, and liver abscess. All complications could be managed non-surgically. CONCLUSION: Repeated single-session PEI is effective in patients with advanced HCC at an acceptable and manageable complication rate. Patients stratified to a combination of TACE and PEI can expect longer survival than those stratified to repeated PEI alone. Furthermore, patients with large or multiple tumors in good clinical status may also profit from a combination of TACE and reconsideration for secondary PEI.
