The psychosocial impact of bilateral prophylactic mastectomy: prospective study using questionnaires and semistructured interviews

OBJECTIVES: To investigate the psychosocial impact of bilateral prophylactic mastectomy for women with increased risk of breast cancer and to identify, preoperatively, risk factors for postoperative distress. DESIGN: Prospective study using interviews and questionnaire assessments. SETTING: Participants' homes throughout the United Kingdom. PARTICIPANTS: 143 women with increased risk of developing breast cancer who were offered bilateral prophylactic mastectomy and who accepted or declined the surgery; a further 11 were offered surgery but deferred making a decision. MAIN OUTCOME MEASURES: Psychological and sexual morbidity. RESULTS: Psychological morbidity decreased significantly over time for the 79 women who chose to have surgery (accepters): 58% (41/71) preoperatively v 41% (29/71) 6 months postoperatively (difference in percentages 17%, 95% confidence interval 2% to 32%; P=0.04) and 60% (39/65) preoperatively v 29% (19/65) 18 months postoperatively (31%, 15% to 47%; P<0.001). Psychological morbidity in the 64 women who declined surgery (decliners) did not decrease significantly: 57% (31/54) at baseline v 43% (23/54) at 6 months (14%, 0% to 29%; P=0.08) and 57% (29/52) at baseline v 41% (21/52) at 18 months (16%; -2% to 33%; P=0.11). Greater than normal proneness to anxiety was more common in the decliners than in the accepters: 78% (45/58) v 56% (41/73) (22%, 6% to 38%; P=0.006). Accepters were more likely than decliners to believe it inevitable that they would develop breast cancer (32% (24/74) v 10% (6/58) (difference in percentages 22%, 9% to 35%; P=0.003)), and decliners were more likely to believe that screening could help (92% (55/60) v 74% (55/74) (18%, 5% to 31%; P=0.007)). Level of sexual discomfort and degree of sexual pleasure did not change significantly over time in either of the two groups. CONCLUSIONS: Bilateral prophylactic mastectomy may provide psychological benefits in women with a high risk of developing breast cancer

Analysis of survival following treatment of tumour-induced hypercalcaemia with intravenous pamidronate (APD).

The outcome of 114 patients with tumour-induced hypercalcaemia (TIH) treated between January 1992 and June 1993 with intravenous pamidronate (APD) was retrospectively analysed. The median overall survival was 55 days (range 3 days to > 21 months): 86 days if systemic anti-cancer therapy was available and only 35 days if not (P < 0.001). Survival was also significantly better for those who became normocalcaemic post APD (53 days vs 19 days, P < 0.001). There was no survival difference with respect to patient sex, age, tumour type, treatment of bone metastases with radiotherapy, initial calcium level, initial dose of APD or time from tumour diagnosis to first TIH. In those patients in whom systemic anti-cancer therapy is available, treatment with APD improves survival, but in all other patients the primary aim of treatment should be symptom control. This study confirms the dismal prognosis of TIH

Immunohistochemical Ki67 after short-term hormone therapy identifies low-risk breast cancers as reliably as genomic markers.

BACKGROUND: The purpose of this study was to test whether immunohistochemical (IHC) Ki67 levels after short-term preoperative hormone therapy (post-Ki67) predict similar numbers of patients with favorable prognoses as genomic markers. RESULTS: Thirty paired cases (60 samples) were enrolled in this study. Post-Ki67 levels were significantly lower than pre-treatment Ki67 levels (P < 0.001). Post-Ki67 predicted more low-risk cases (83.3%, 25/30) than pre-genomic surrogate signature(GSS) (66.7%: 20/30), but the difference in predictive power was not significant (P = 0.233). Proliferation (MKI67, STK15, Survivin, CCNB1, and MYBL2) and estrogen (ER, PGR, BCL2, and SCUBE2) related signatures were significantly downregulated after therapy (P < 0.001 and 0.041, respectively). MATERIALS AND METHODS: Core needle biopsy specimens of primary breast cancer were collected at Okayama University Hospital from hormone receptor-positive and human epidermal growth factor 2-negative patients that subsequently received two weeks of neoadjuvant hormone therapy. Paired post-treatment specimens from surgical samples were also collected. IHC Ki67 levels and GSS were compared between pre- and post-hormone treatment samples. Changes of gene expression pattern in short-term hormone therapy were also assessed. CONCLUSIONS: IHC based post-Ki67 levels may have distinct predictive power compared with the naive IHC Ki67. Future studies with larger cohorts and longer follow-up periods may be needed to validate our results
