Spiegel et al. (1989) conducted a prospective intervention study of patients with metastatic breast cancer. Findings demonstrated that a weekly support group meeting for one year enhanced patients’ psychosocial functioning and reduced pain as compared to a standard care treatment control group. Further, in a ten-year follow-up, the data reported that survival was significantly different, with a mean of months in the intervention group compared with months in the control group. Another study, conducted by Fawzy and colleagues (1993) supported these findings. Early-stage melanoma patients assigned to a six-week psychosocial intervention demon- strated increases in coping skills, but no affect on negative mood states or immune. | Int. J.

Most lung cancers are squamous cell carcinoma small cell carcinoma or adenocarcinoma trends vary according to type. We compiled populationbased morphology-specific incidence data from registries contributing to the International Agency for Research on Cancer IARC databases. Unspecified cancers and carcinomas were reallocated based on a registry time period sex and age group-specific basis. Where available data from several registries within a country were pooled for analysis. Rates per 100 000 person-years for 1980-1982 to 1995-1997 were age-adjusted by the direct method using the world standard. Squamous cell carcinoma rates among males declined 30 or more in North America and some European countries while changing less dramatically in other areas small cell carcinoma rates decreased less rapidly. Squamous and small cell carcinoma rates among females generally rose with the increases especially pronounced in the Netherlands and Norway. In contrast adenocarcinoma rates rose among males and females in virtually all areas with the increases among males exceeding 50 in many areas of Europe among females rates also rose rapidly and more than doubled in Norway Italy and France. Rates of all lung cancer types among women and adenocarcinoma among men continue to rise despite declining cigarette use in many Western countries and shifts to filtered low-tar cigarettes. Renewed efforts toward cessation and prevention are mandatory to curb
