 An increasing number of women who undergo immediate two-stage tissue expander/implant breast reconstruction will require postmastectomy radiation therapy. An important variable is the timing of radiotherapy relative to surgery. The authors report their experience treating a large consecutive series of patients who underwent postmastectomy radiation therapy to the tissue expander before exchange for a permanent implant.

Case Study: Jim Mathis is a 45-year-old health-conscious man who has been a patient in an internal medicine–primary care practice for several years. At today’s visit, he talks about the family tree that he has sketched out and his discovery that three of his relatives had cancer — one had breast cancer, one ovarian cancer, and one prostate cancer.

Postmastectomy radiation in breast cancer with one to three involved lymph nodes

Many trials in breast cancer have investigated various aspects of locoregional and systemic treatments. Combination of the results of these trials in a meticulous meta-analysis, as has been done several times by the Early Breast Cancer Trialists' Collaborative Group (EBCTCG), fills the gaps in evidence and knowledge by conclusively showing significant trends and differences.

Adjuvant exemestane with ovarian suppression in premenopausal breast cancer

The most effective adjuvant endocrine therapy for premenopausal women with hormone-receptor (estrogen, progesterone, or both)–positive breast cancer is uncertain. Tamoxifen for at least 5 years is a standard of care. Adjuvant suppression of ovarian function (hereafter, ovarian suppression) may be recommended in addition. For postmenopausal women, adjuvant therapy with an aromatase inhibitor, as compared with tamoxifen, improves outcomes.

Portrait, treatment choices and management of breast cancer in nonagenarians

There are only scarce data on the management of nonagenarians with breast cancer, and more particularly on the place of radiation therapy (RT). We report a retrospective study on patients aged 90 years old or older, with breast cancer, receiving RT. Records from RT departments from five institutions were reviewed to identify patients 90 years old of age and older undergoing RT over past decade for breast cancer. Tumors' characteristics were examined, as well treatment specificities and treatment intent. 

44 patients receiving RT courses were identified, mean age 92 years. Treatment was given with curative and palliative intent in 72.7% and 27.3% respectively. Factors associated with a curative treatment were performance status (PS), place of life, previous surgery, and tumor stage. Median total prescribed dose was 40 Gy (23–66). Hypo fractionation was used in 77%. Most toxicities were mild to moderate. RT could not be completed in 1 patient (2.3%). No long-term toxicity was reported. Among 31 patients analyzable for effectiveness, 24 patients (77.4%) had their diseased controlled until last follow-up, including 17 patients (54.8%) experiencing complete response. At last follow-up, 4 patients (12.9%) were deceased, cancer being cause of death for two of them.

The study shows that breast/chest RT is feasible in nonagenarians. Although the definitive benefit of RT could not be addressed here, hypofractionated therapy allowed a good local control with acceptable side effects.

Effect of radiotherapy after mastectomy and axillary surgery on 10-year recurrence and 20-year breast cancer mortality

Postmastectomy radiotherapy was shown in previous meta-analyses to reduce the risks of both recurrence and breast cancer mortality in all women with node-positive disease considered together. However, the benefit in women with only one to three positive lymph nodes is uncertain. We aimed to assess the effect of radiotherapy in these women after mastectomy and axillary dissection.

Breast cancer drug hope for leukaemia

Leukaemia research may lead to new drugs for difficult-to-treat breast cancers, say scientists.

These types of tumours cannot be treated with the targeted drugs which have hugely improved survival.

A team in Glasgow says a faulty piece of DNA which causes leukaemia also has a role in some tumours and could help in research for new drugs. 

Meanwhile, other researchers say they have taken tentative steps towards a blood test for breast cancer.
