SummaryThe diagnosis and treatment of breast cancer are stressful, and stress may be associated with a poorer response to chemotherapy. There is a need, therefore, to develop and evaluate interventions that might enhance quality of life and, possibly, improve treatment response. The effects of relaxation combined with guided imagery (visualizing host defences destroying tumour cells) on quality of life and response to primary chemotherapy, to date, have not been adequately evaluated. Ninety-six women with newly diagnosed large or locally advanced breast cancer (T 2 > 4 cm, T 3 , T 4 , or T x N 2 and M 0 ) took part in a prospective, randomized controlled trial. Patients were randomized following diagnosis to a control condition (standard care) or to the experimental condition (standard care plus relaxation training and imagery). Psychometric tests to evaluate mood and quality of life were carried out before each of the six cycles of chemotherapy and 3 weeks after cycle 6: tests of personality and coping strategy were carried out prior to cycles one and six. Clinical response to chemotherapy was evaluated after six cycles of chemotherapy using standard UICC criteria and pathological response was assessed from the tissue removed at surgery. As hypothesized, patients in the experimental group were more relaxed and easy going during the study (Mood Rating Scale). Quality of life was better in the experimental group (Global Self-assessment and Rotterdam Symptom Checklist). The intervention also reduced emotional suppression (Courtauld Emotional Control Scale). The incidence of clinically significant mood disturbance was very low and the incidence in the two groups was similar. Finally, although the groups did not differ for clinical or pathological response to chemotherapy, imagery ratings were correlated with clinical response. These simple, inexpensive and beneficial interventions should be offered to patients wishing to improve quality of life during primary chemotherapy.

A cluster of five patients with endometrial carcinosarcoma (malignant mixed Müllerian tumor) occurred at our center during 1993; four of these had been prescribed long-term tamoxifen for breast carcinoma. Searching the archives for the 9-year period 1983-1992 revealed two further cases of uterine carcinosarcoma occurring in patients prescribed tamoxifen, from a total of 16 cases of this tumor. Five of the six patients diagnosed with carcinosarcoma who had been taking tamoxifen had been maintained on the drug for at least 6 years, while the other had a 3-year history of tamoxifen therapy. From these data we raise the question of an association between long-term tamoxifen treatment and development of endometrial carcinosarcoma, following the dramatic increase in the prescribing of this drug after 1984.

Mutation of the p53 tumor suppressor gene is the most commonly observed genetic abnormality in human tumors and associations between p53 aberration and patient survival have been shown for several tumor types. Previous studies have found that approximately 50% of epithelial ovarian carcinomas exhibit abnormalities in the p53 gene. The aim of this study, therefore, was to examine the potential prognostic significance of aberrant p53 in patients with primary epithelial ovarian carcinoma. Using immunohistochemistry (IHC) and the anti‐p53 antibodies CM1, PAb240 and PAb1801, p53 over‐expression was observed in 20/39 (51%) tumors. When these results were combined with previously reported IHC and sequencing analyses, 37/61 (61%) tumors exhibited a p53 aberration. Although there was no significant difference between sequencing and IHC results, several cases gave discordant results, indicating that a combination of both methods may be required to estimate accurately the proportion of tumors with p53 aberrations. Univariate statistical analysis showed that p53 aberrations were significantly associated with tumor grade 3/4, FIGO stage III/IV, serous tumors and the presence of bulk (>2 cm) residual disease following surgery. In univariate survival analysis, tumor grade and stage, ascites and post‐surgical residual tumor> 2 cm were associated with both overall survival (OS) and disease‐free survival (DFS). p53 status, however, was not a predictor of either OS or DFS. Using the Cox proportional hazards model, only FIGO stage and post‐surgical residual disease> 2 cm had an independent effect on OS and only stage was found to be an independent predictor of DFS. In conclusion, p53 mutation and overexpression does not appear to be a significant indicator of patient survival in this series of ovarian carcinomas.
