Understanding the Needs of Patients with Metastatic Breast Cancer: Results of the Make Your Dialogue Count Survey.

With more patients with metastatic breast cancer (MBC) living longer, patient-centered communication and shared decision making between patient and oncologist are vital to improve care and quality of life in patients with MBC. The Make Your Dialogue Count survey explored emotional needs of patients at initial diagnosis of MBC and treatment change to increase awareness about gaps and facilitate communication between patients and oncologists. The survey was conducted (June-August 2014) online, by telephone, or on paper among US women with MBC and US-licensed medical oncologists.

PAM50 gene signatures and breast cancer prognosis with adjuvant anthracycline- and taxane-based chemotherapy: correlative analysis of C9741 (Alliance).

PAM50 intrinsic breast cancer subtypes are prognostic independent of standard clinicopathologic factors. CALGB 9741 demonstrated improved recurrence-free (RFS) and overall survival (OS) with 2-weekly dose-dense (DD) versus 3-weekly therapy. A significant interaction between intrinsic subtypes and DD-therapy benefit was hypothesized.

Feasibility and cardiac safety of trastuzumab emtansine after anthracycline-based chemotherapy as (neo)adjuvant therapy for human epidermal growth factor receptor 2-positive early-stage breast cancer.

Purpose: Trastuzumab emtansine (T-DM1), an antibody-drug conjugate comprising the cytotoxic agent DM1, a stable linker, and trastuzumab, has demonstrated substantial activity in human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer, raising interest in evaluating the feasibility and cardiac safety of T-DM1 in early-stage breast cancer (EBC).

Patients And Methods: Patients (N = 153) with HER2-positive EBC and prechemotherapy left ventricular ejection fraction (LVEF) ≥ 55% received (neo)adjuvant doxorubicin plus cyclophosphamide or fluorouracil plus epirubicin plus cyclophosphamide followed by T-DM1 for four cycles. Patients could then receive three to four cycles of optional docetaxel with or without trastuzumab.

Isolated sternal involvement in breast cancer: is it truly stage IV disease?

Purpose: There is no consensus regarding treatment for patients with breast cancer and isolated sternal involvement. Though classified as AJCC stage IV, this group of patients may have prolonged distant disease free survival.

Patients And Methods: Retrospective case series of 8 patients with isolated sternal recurrence.

Dose-Dense Chemotherapy: Principles, Clinical Results and Future Perspectives.

The dose intensity of adjuvant chemotherapy for breast cancer is an important predictor of clinical outcome. Dose-dense chemotherapy increases the dose intensity of the regimen by delivering standard-dose chemotherapy with shorter intervals between the treatment cycles. The rationale for dose-dense therapy stems from the Norton-Simon hypothesis: Sequential, consecutive dosing of chemotherapy using single or a combination of agents increases the dose density over alternating dosing, improving results.

Toxicity of older and younger patients treated with adjuvant chemotherapy for node-positive breast cancer: the Cancer and Leukemia Group B Experience.

Purpose: Older node-positive patients treated with newer adjuvant chemotherapy regimens have improvements in relapse-free and overall survival similar to younger patients. We compared toxicity of older and younger patients in three randomized trials of adjuvant chemotherapy.

Patients And Methods: Toxicity data were available for 93% of 6,642 patients enrolled.

Estrogen-receptor status and outcomes of modern chemotherapy for patients with node-positive breast cancer.

Context: Breast cancer estrogen-receptor (ER) status is useful in predicting benefit from endocrine therapy. It may also help predict which patients benefit from advances in adjuvant chemotherapy.

Objective: To compare differences in benefits from adjuvant chemotherapy achieved by patients with ER-negative vs ER-positive tumors.

Dose density in adjuvant chemotherapy for breast cancer.

Background: Dose-dense chemotherapy increases the dose intensity of the regimen by delivering standard-dose chemotherapy with shorter intervals between the cycles. This article discusses the rationale for dose-dense therapy and reviews the results with dose-dense adjuvant regimens in recent clinical trials in breast cancer.

Methods: The papers for this review covered evidence of a dose-response relation in cancer chemotherapy; the rationale for dose-intense (and specifically dose-dense) therapy; and clinical experience with dose-dense regimens in adjuvant chemotherapy for breast cancer, with particular attention to outcomes and toxicity.

Adipose concentrations of organochlorine compounds and breast cancer recurrence in Long Island, New York.

Several studies have measured the association between blood or adipose concentrations of organochlorinated compounds (OCs), such as pesticides and polychlorinated biphenyls (PCBs), and breast cancer. The estrogenic effects of OCs might adversely affect breast cancer recurrence. The participants were 224 women with nonmetastatic breast cancer enrolled in a New York-based case-control study.

Lung cancer risk in white and black Americans.

Purpose: To test whether differences in smoking-related lung cancer risks in blacks and whites can explain why lung cancer incidence is greater in black males than in white males but about equal in black and white females, given that a greater proportion of blacks are smokers, but smoke far fewer cigarettes per day than do whites.

Methods: A hospital-based case-control study was conducted between 1984 and 1998 that included interviews with 1,710 white male and 1,321 white female cases of histologically confirmed lung cancer, 254 black male and 163 black female cases, and 8,151 controls. Relative risks were estimated via odds ratios using logistic regression, adjusted for age, education, and body mass index.

Randomized trial of dose-dense versus conventionally scheduled and sequential versus concurrent combination chemotherapy as postoperative adjuvant treatment of node-positive primary breast cancer: first report of Intergroup Trial C9741/Cancer and Leukemia Group B Trial 9741.

Purpose: Using a 2 x 2 factorial design, we studied the adjuvant chemotherapy of women with axillary node-positive breast cancer to compare sequential doxorubicin (A), paclitaxel (T), and cyclophosphamide (C) with concurrent doxorubicin and cyclophosphamide (AC) followed by paclitaxel (T) for disease-free (DFS) and overall survival (OS); to determine whether the dose density of the agents improves DFS and OS; and to compare toxicities.

Patients And Methods: A total of 2,005 female patients were randomly assigned to receive one of the following regimens: (I) sequential A x 4 (doses) --> T x 4 --> C x 4 with doses every 3 weeks, (II) sequential A x 4 --> T x 4 --> C x 4 every 2 weeks with filgrastim, (III) concurrent AC x 4 --> T x 4 every 3 weeks, or (IV) concurrent AC x 4 --> T x 4 every 2 weeks with filgrastim.

Results: A protocol-specified analysis was performed at a median follow-up of 36 months: 315 patients had experienced relapse or died, compared with 515 expected treatment failures.
