Phase II study of thalidomide in patients with unresectable hepatocellular carcinoma.

BACKGROUND: The hypervascular nature of hepatocellular carcinoma (HCC) is well characterized. Recent data have suggested that thalidomide possesses antiangiogenic and immunomodulatory activity. Therefore, the authors initiated a study to assess the efficacy and toxicity of thalidomide in patients with advanced HCC as primary and secondary endpoints, respectively. METHODS: Inclusion criteria were unresectable HCC with bidimentionally measurable disease, age > or = 18 years, Eastern Cooperative Oncology Group performance status < or = 2, and adequate organ function. Thalidomide was administered at a starting dose of 200 mg per day in a 100-mg-per-week dose escalation regimen, up to the maximum tolerated dose or to 800 mg per day. Toxicity was monitored according to the National Cancer Institute Common Toxicity Criteria. RESULTS: Twenty-six of 27 patients were eligible and assessable for toxicity and response. A median daily dose of 300 mg was achieved. One patient experienced near-complete recovery of alpha-fetoprotein levels and a partial radiographic response on computed tomography. Two patients had stable disease during the 16-week study period. The median duration of progression-free survival was 42 days. The overall median survival was 123 days. Fatigue and somnolence were the most common side effects, occurring in 81% and 62% of patients, respectively. No Grade 4 hematologic toxicity was observed. Three patients experienced Grade 4 hepatic toxicity (namely, hyperbilirubinemia). CONCLUSIONS: With gradual dose escalation, thalidomide was tolerated in most patients with advanced HCC. However, treatment with thalidomide alone was associated with only a modest response in the treatment of HCC.

HLA-DR, HLA-DQ, and TAP genes in familial Hodgkin disease.

The HLA region has long been implicated in sporadic and familial Hodgkin disease (HD), with recent case-control studies suggesting that HLA class II loci predispose to sporadic nodular sclerosis HD (NSHD). To determine whether this predisposition extends to familial HD, HLA class II loci (DRB1, DQA1, DQB1, DRB3, DRB4, and DRB5) and transporter associated with antigen processing (TAP) loci (TAP1, TAP2) were investigated in 100 members of 16 families with at least 2 confirmed cases of HD. With the use of the transmission disequilibrium test, evidence for linkage disequilibrium with familial HD and, in particular, familial NSHD was obtained for the DRB1*1501-DQA1*0102-DQB1*0602 haplotype, the TAP1 allele encoding Ile at residue 333, and the DRB5-0101 allele. These 3 markers were in linkage disequilibrium and may not represent independent susceptibility regions. Use of a family-based approach excludes population stratification as an explanation for these findings.

Breast cancer characteristics of Vietnamese women in the Greater San Francisco Bay Area.

OBJECTIVES: To examine breast cancer characteristics of women of Vietnamese ancestry living in the San Francisco Bay Area in comparison with those of other racial or ethnic groups in the same area. DESIGN: Data were obtained from the population-based Greater Bay Area Cancer Registry, part of the Surveillance, Epidemiology, and End Results program. We included breast cancer cases diagnosed from 1988 to 1999 and compared the age at diagnosis, stage and histologic grade at diagnosis, estrogen- and progesterone-receptor status, and surgery types across racial or ethnic groups. We also modeled the effect of patient and clinical characteristics and hospital and physician on the racial or ethnic variations in surgery type. RESULTS: Vietnamese women were younger at diagnosis than other racial or ethnic subgroups (mean age, 51.0 years), with 49.6% of the diagnoses occurring in patients younger than 50. They were also significantly more likely to have received mastectomy for their in situ and localized tumors (61.1% having mastectomy) than women of other racial or ethnic groups. The increased likelihood of having mastectomy among Vietnamese women was not affected greatly by age, year of diagnosis, tumor stage, histologic grade, or physician, but was partly attributable to the hospital of diagnosis. CONCLUSIONS: The effects of a lower mean age at diagnosis and the reasons for an unexpectedly higher percentage of mastectomies in this Asian subgroup should be further explored.
