In the future, we also need to improve our ability to personalize the duration of endocrine therapy, with a goal of optimizing patient selection for extended therapy. Hopefully, clinical-pathologic indices and predictive biomarkers similar to the Oncotype DX 12-gene recurrence score or the PAM50 risk of recurrence score for adjuvant chemotherapy will soon emerge to guide adjuvant endocrine therapy.

The review by Drs. Ruta Rao and Melody Cobleigh in this issue of ONCOLOGY summarizes the state-of-the-art adjuvant hormonal therapy for breast cancer concisely and appropriately.

The article “Adjuvant Hormonal Therapy in Premenopausal Women With Operable Breast Cancer: Not-So-Peripheral Perspectives” by Richard Love, published in this issue of ONCOLOGY,

Developed over a century ago,[1] endocrine therapy remains the most effective and the most clearly targeted form of systemic therapy for breast cancer. Endocrine treatments work best in women whose tumors are positive for estrogen receptors (ER) and/or progesterone receptors (PR).

Breast cancer is a systemic diseasewith 10-year relapse risksafter surgery alone ranging between30% and 50%.[1] About 60%to 75% of breast cancers are hormonereceptor–positive[2] and are potentiallyresponsive to endocrine therapy,which remains a cornerstone in the adjuvanttherapy of such tumors in thisera of targeted therapy and genomics.

This excellent summary of theassociation of overweight andobesity with increased incidenceand poorer prognosis in a varietyof cancers is well worth the reader'sattention. Dr. McTiernan presents literaturesuggesting that overweight isassociated with increased incidenceand mortality in a variety of types ofcancer. In the case of breast cancer,for which there are more data than anyother cancer site, the increased risk ofmortality appears to be in part relatedto increased incidence in postmenopausalwomen, and to a poorer prognosisassociated with both overweightand weight gain following diagnosis.

This excellent and practical articleby Dr. Ravdin is worthwhilereading for every physician involvedin the long-term care of womenwith a previous diagnosis of breastcancer. Dr. Ravdin clearly outlinesthe theoretical rationale underlying theincreased risk of osteopenia and osteoporosisin women with a history ofbreast cancer. The fact that such womencommonly undergo prematuremenopause either deliberately, as partof treatment for breast cancer, or as asecondary effect of chemotherapy, andthat estrogen-replacement therapywith or without progesterone remainscontraindicated for fear of increasingthe risk of recurrence, clearly contributesto the increased possibility ofdeveloping osteopenia or osteoporosis.New data supporting the role ofaromatase inhibitors in adjuvant therapy[

Barton, Loprinzi, and Gostout provide a comprehensive, accurate, and multidisciplinary review of the management of menopausal symptoms in patients with a previous diagnosis of cancer. The article is clearly enhanced by the authorship of individuals from different backgrounds, each of whom bring a valuable perspective to the subject. Additional attention to several issues would, however, make interpretation of the data on this subject, and hence, the management of patients with these problems, more clear.

In addition to ovarian ablation by means of surgery or irradiation, a wide variety of endocrine agents are now available for the management of breast cancer, in both the metastatic and adjuvant settings. Currently available

Problem: Several million women worldwide have survived breast cancer but are currently advised against the use of estrogen for the management of menopausal symptoms and for the prevention of early cardiovascular death and osteoporosis.

There are several million breast cancer survivors worldwide. In the United States, 180,000 women were diagnosed with breast cancer in 1997, and approximately 97,000 of these women have an extremely low chance of a suffering a recurrence of their cancer. With an average age at diagnosis of 60 years and a 25-year expected duration of survival, the current number of breast cancer survivors in the United States may approach 2.5 million women. Since breast cancer is now being detected at an earlier stage than previously and since adjuvant chemotherapy may cause ovarian failure, an increasing number of women are becoming postmenopausal at a younger age after breast cancer treatment. This conference was convened in September 1997 to consider how menopausal breast cancer survivors should be treated at the present time and what future studies are needed to develop improved therapeutic strategies. A total of 47 breast cancer experts and 13 patient advocates participated. The proceedings of the conference are being published in six installments in successive issues of oncology. This third part focuses on the prevention of osteoporosis and the cardiovascular effects of estrogens and antiestrogens. [ONCOLOGY 13(3):397-432, 1999]

This conference was convened in September 1997 to consider how menopausal breast cancer survivors should be treated at the present time and what future studies are needed to develop improved therapeutic strategies. A total of 59 breast cancer experts and patient advocates participated. The proceedings of the conference will be published in six installments in successive issues of oncology. The first part, published last month, defined the problem and explored its magnitude and ramifications for patient management. This second part focuses on the benefits and risks of hormone replacement therapy (HRT) in patients with breast cancer. [ONCOLOGY 13(2):245-267, 1999]

Dr. Smith's excellent article summarizes the preclinical and clinical data obtained to date on the role of vinorelbine (Navelbine) in women with breast cancer. Introducing a new agent into the arena of breast cancer is fraught with logistic
