Abstract:We recently reported on the willingness to pay (WTP) for prostate cancer screening with prostate specific antigen (PSA) using the contingent valuation method (CVM). This study, a continuation of the work outlined in the previous report, comprises a more precise and detailed survey. In an Internet questionnaire survey, 400 men aged 50-59 in Japan were randomly split into two groups: the ill-informed group (n = 207), which was provided with information about the detection rate, and the well-informed group (n = 193), which was given additional information about false positive/negative results, latent cancer, and the yet-to-be-demonstrated mortality-reducing effect of the test. The mean WTP was ¥1670 ($15.2). Giving sufficient information would not decrease WTP for PSA screening. Men place a high value on 'peace of mind' through the ascertaining of no sign of cancer at the present rather than on the future-oriented life-saving effects that may be gained through such screening.

“…In the United States and Europe, the mortality rate is being effectively decreased as a result of increased screening and advances in adjunct therapy. However, in Japan, both the number of breast cancer patients and the mortality rate are on the rise [1]. Breast cancers can be classified into five phenotypes on the basis of recent gene-expression profiling analytical techniques: the normal breast type, luminal A, luminal B, Her2 type, and basal type [2][3][4][5][6].…”

Background: Triple-negative breast cancer (estrogen receptor-negative, progesterone receptor-negative and Her2-negative) can be classified into two subtypes: basal and non-basal phenotype. Among these subtypes the basal phenotype is associated with poor outcome. Ordinarily, clinicopathological testing involves only screening for ER, PgR and Her2, and for this reason the therapeutic approach that is decided for triplenegative disease is usually the same regardless of the subtype. Methods: Immunohistochemical staining was performed for the CK5/6, CK14, and CK17 basal markers in 66 triple-negative patients for the purpose of classifying as basal or non-basal phenotype, and the clinicopathology was investigated. Results: Forty (60.1%) were the basal phenotype. Compared with the non-basal phenotype, the basal phenotype lesions were significantly larger in diameter, higher incidences of EGFR-positive and a high nuclear grade. In the node-negative group the basal phenotype clearly showed those same clinicopathological differences and a higher incidence of distal recurrence compared with the non-basal phenotype. Conclusions: Although there was the small number of the patients, this study results show that it is important to perform basal marker immunohistochemical staining and classify lesions as the basal or the non-basal phenotype, since this will aid in deciding the therapeutic strategy for triple-negative breast cancer.
