An inverse association either between depression or impaired functional status and quality of life (QoL) has been reported for cancer patients, but the independent effect of depression or depressive symptoms and of functional impairment on QoL is unclear. ⋯ Signs of major depression or depressive symptoms and impaired functional status contribute independently to poorer QoL in cancer patients prior to chemotherapy.

Multicenter Study Comparative Study
Parent distress in childhood cancer: a comparative evaluation of posttraumatic stress symptoms, depression and anxiety.
The aim was to assess symptoms consistent with posttraumatic stress (PTS; cognitive intrusions, avoidance, arousal) related to the child's illness, and generic distress (anxiety, depression) in parents of childhood cancer patients. Outcomes were compared to normative and relevant reference data, and analysed for their dependence on time passed since diagnosis. Swedish parents (266 mothers, 208 fathers) were recruited at two centres. ⋯ Clinically, attention should be paid to continuous parent support needs. Individual variation vis-à-vis distress vulnerability should be acknowledged, and presupposed gender differences avoided. When treatment situation asks the most of parents' collaboration, many are under pressure of severe stress.

Comparative Study
Variation in radiation sensitivity and repair kinetics in different parts of the spinal cord.
The spinal cord, known for its strongly serial character and high sensitivity to radiation even when a small segment is irradiated, is one of the most critical organs at risk to be spared during radiation therapy. To compare the sensitivity of different parts of the spinal cord, data for radiation myelopathy have been used. ⋯ Large differences in radiation response between the cervical and thoracic region of spinal cord are thus observed: cervical myelopathy seems to be characterized by medium seriality, while thoracic spinal cord is characterized by a highly serial dose-response. The much steeper dose-response curve for cervical spinal cord myelopathy can be interpreted as a higher number of functional subunits consistent with a higher amount of white matter close to the brain.

The present study epidemiologically clarified the different roles of Helicobacter pylori (Hp) infection in carcinogenesis between two major histological types of noncardia gastric cancer (ncGC), intestinal (=differentiated) and diffuse (=undifferentiated), by analyzing IgG antibody titer against Hp surface antigen on the data set of a nested case-control study in a large cohort study conducted in Japan. ⋯ Our study epidemiologically confirmed that atrophic changes caused by Hp infection determine the development of differentiated-type ncGC, and the inflammation itself induced by Hp infection promotes the development of undifferentiated-type ncGC.

Trastuzumab is a monoclonal antibody that together with chemotherapy significantly improves time to progression and overall survival for metastatic breast cancer patients with tumours overexpressing HER2. The aim of this study was to analyse the cost-effectiveness of HER2 testing and trastuzumab in combination with chemotherapy compared with chemotherapy alone from a societal perspective in a Swedish setting. ⋯ Our analysis indicate that FISH testing for all patients with trastuzumab and chemotherapy treatment for FISH positive patients is a cost-effective treatment option from a societal perspective.
