Between 30% and 70% of western women experience psychological morbidity after undergoing surgery for breast carcinoma; however, the rates and risk factors among Chinese women are unknown. Identifying at-risk women enables preventive intervention. ⋯ Psychological morbidity was linked to women's TDM difficulties, their inability to anticipate treatment effects accurately, and physical symptom distress, possibly exacerbated by symptom misattribution. Optimizing TDM support and helping women accurately determine outcomes in terms of symptom experience and meaning and physical appearance may help to reduce psychological morbidity. Women who have TDM difficulties should be considered to be at high risk for psychological distress.

The human polyomavirus JC virus (JCV) causes progressive multifocal leukoencephalopathy. Subclinical infection with JCV occurs in 85-90% of the population worldwide. The virus usually remains latent but can reactivate under immunosuppressive conditions, resulting in progressive multifocal leukoencephalopathy. JCV is oncogenic in experimental animals and is associated with human brain tumors. JCV is found in normal mucosa of the gastrointestinal tract, and some colon carcinomas express the oncogenic JCV T-antigen protein. The objective of this study was to examine the presence of JCV DNA sequences and JCV protein expression in normal and malignant human esophageal tissues. ⋯ The results provide evidence for infection of gastrointestinal tract cells by JCV and suggest a potential role of JCV in the development of upper digestive tract carcinomas.

The National Cancer Institute (NCI) designates cancer centers as regional centers of excellence in research and patient care. Although these centers often advertise their superior outcomes, their relative performance has not been examined empirically. In the current study, the authors assessed whether patients at NCI cancer centers compared with patients at control hospitals had lower mortality rates after major cancer surgery. ⋯ For many cancer procedures, patients undergoing surgery at NCI-designated cancer centers had lower surgical mortality rates than those treated at comparably high-volume hospitals, but similar long-term survival rates.
