External-beam radiation therapy for age-related macular degeneration: two years' follow-up results at a total dose of 20 Gy in 10 fractions.

Purpose: The efficacy of external-beam radiation therapy (RT) was evaluated in the treatment of eyes with subfoveal or juxtafoveal choroidal neovascularization in age-related macular degeneration (ARMD).

Materials And Methods: Twenty-one eyes of 18 patients with occult or mixed-type ARMD received a total dose of 20 Gy of 6 MV X-rays in 10 fractions. The follow-up time was 24 months.

Preoperative assessment of multicentric occurrence in synchronous small and multiple hepatocellular carcinoma based on image-patterns and histological grading of non-cancerous region.

Recent studies have shown that the prognosis of patients with multicentric occurrence (MO) of hepatocellullar carcinoma (HCC) after curative resection, whether synchronous or metachronous, is significantly better than that of patients with intrahepatic metastasis (IM). We attempted to elucidate a group with high probability of MO of HCC by comparing the preoperative ultrasonography (US), computed tomography during arterial portography (CTAP) and CT arteriography (CTA) images with the histological grading of the non-cancerous region of the liver. The imaging and pathological characteristics of 97 nodules in 45 patients diagnosed as having small (<5cm) and oligonodular HCCs preoperatively were investigated.

Prognosis of hepatocellular carcinoma associated with Child class B and C cirrhosis in relation to treatment: a multivariate analysis of 411 patients at a single center.

Background/purpose: Given that the prognosis of patients with hepatocellular carcinoma (HCC) complicating severe cirrhosis remains uncertain, particularly with regard to various therapeutic strategies, we have evaluated the prognosis in a series of patients with homogeneous diagnostic and therapeutic histories.

Methods: From 1990 to 1998, 411 consecutive HCC patients associated with Child class B and class C cirrhosis who did not have lymph node or distant metastasis were treated by partial hepatectomy (PH; n = 48), percutaneous ethanol injection (PEI; n = 105), transcatheter arterial chemoembolization (TACE; n = 189), chemotherapy, or supportive care (chemo/supportive; n = 69). Univariate survival curves were estimated.

Prognostic performance of the new classification of primary liver cancer of Japan (4th edition) for patients with hepatocellular carcinoma: a validation analysis.

The Japanese staging system that is generally used for hepatocellular carcinoma (HCC) (3rd edition) was considerably revised recently, especially T category. No study, however, has revealed how well the new classification (4th edition) works to stratify HCC patients at a pre-intervention stage. The purpose of this study is to assess the discriminatory value and predictive power of the 4th edition, and to compare its utility with the clinical utilities of the 3rd edition and the cancer of the liver Italian program (CLIP) score, as determined from 662 Japanese patients.
