Metastatic tumors to the breast from colon adenocarcinomas are very rare. They are indicative of disseminated disease, so their prognosis is poor. In such cases radical operation should be avoided unless for palliation purposes. Partial mastectomy with chemotherapy is adequate therapy and offers the patient an aesthetic and oncologically safe surgical procedure. We report the first case of recurrent breast cancer metastatic from a colon adenocarcinoma after review of the literature. Source

Background: A dose-dense strategy has been considered to improve results of adjuvant chemotherapy for breast cancer. This randomised phase II trial investigated the feasibility of this approach with sequential anthracyclines and taxanes-based chemotherapy. Methods: Patients with high-risk node-positive breast cancer were treated with three cycles of fluorouracil 500 mg m -2, epirubicin 100 mg m -2, cyclophosphamide 500 mg m -2 (FEC 100) followed by three cycles of docetaxel 100 mg m -2 delivered at 2-weekly intervals supported by primary prophylaxis with filgrastim. All patients were randomised to either uninterrupted treatment (arm A) or to have a 2-week additional period of rest between the FEC and docetaxel (arm B). The primary endpoint was the rate of success of chemotherapy delivery. Using a two-stage Fleming design, 120 patients were required with one interim analysis. Results: In March 2005, enrolment was stopped into arm A after the observation of severe skin toxicities. Following the planned interim analysis, the study was closed because of the high rate of grade 3/4 skin toxicities in both arms (arm A: 32.4% and arm B: 18.9%). Conclusion: Sequential dose-dense FEC 100 followed by docetaxel 100 mg m -2 is not feasible. Feasibility still depends largely on several factors including the choice of drugs, dosage and sequence of administration. © 2011 Cancer Research UK All rights reserved. Source

Background: In this study, the authors evaluated the effect of denosumab versus zoledronic acid (ZA) on pain in patients with advanced breast cancer and bone metastases. METHODS: The prevention of pain, reduction in pain interference with daily life activities, and the proportion of patients requiring strong opioid analgesics were assessed in a randomized, double-blind, double-dummy phase 3 study comparing denosumab with ZA for preventing skeletal-related events in 2046 patients who had breast cancer and bone metastases. Patients completed the Brief Pain Inventory-Short Form at baseline and monthly thereafter. RESULTS: Fewer patients who received denosumab reported a clinically meaningful worsening of pain severity (≥2-point increase) from baseline compared with patients who received ZA, and a trend was observed toward delayed time to pain worsening with denosumab versus ZA (denosumab, 8.5 months; ZA, 7.4 months; P =.08). In patients who had no/mild pain at baseline, a 4-month delay in progression to moderate/severe pain was observed with denosumab compared with ZA (9.7 months vs 5.8 months; P =.002). Denosumab delayed the time to increased pain interference by approximately 1 month compared with ZA (denosumab, 16.0 months; ZA, 14.9 months; P =.09). The time to pain improvement (P =.72) and the time to decreased pain interference (P =.92) were similar between the groups. Fewer denosumab-treated patients reported increased analgesic use from no/low use at baseline to strong opioid use. CONCLUSIONS: Denosumab demonstrated improved pain prevention and comparable pain palliation compared with ZA. In addition, fewer denosumab-treated patients shifted to strong opioid analgesic use.

Objective: To evaluate the effects of an 8-week multidimensional physical therapy program, including strengthening exercises and recovery massage, on neck and shoulder pain, pressure hypersensitivity, and the presence of active trigger points (TrPs) in breast cancer survivors. Methods: In this randomized controlled clinical trial, 44 breast cancer survivors were randomly assigned into 2 groups: CUIDATE group who received a multidimensional physical therapy program; or CONTROL group who received usual care treatment for breast cancer. CUIDATE program consisted of 24 hours of individual physical training (aerobic, mobility, stretching, and strengthening exercises) and 12 hours of physical therapy recovery (stretching, massage) interventions (3 times/wk, 90 min). Outcomes included neck and shoulder pain (visual analog scale, 0 to 100), pressure pain thresholds over the C5-C6 zygapophyseal joints, deltoid muscles, second metacarpal and tibialis anterior muscles, and the presence of active TrPs in shoulder muscles. Outcomes were assessed at baseline and after the 8-week program by a blinded assessor. Results: The CUIDATE group showed an estimated improvement for neck pain of-56 mm [95% confidence interval (CI),-71-40, P<0.001; effect size 2.72, 1.94 to 3.44] and for shoulder/axillary of-56 mm (95% CI,-74-38, P<0.001; effect size 2.45, 1.66 to 3.23). Improvements were also noted for pressure pain thresholds levels: C5-C6 zygapophyseal joints (between-group differences 101 kPa, 95% CI, 60-143; effect size 1.68, 1.00 to 2.35; 92 kPa 55 to 129; d: 1.98, 1.18 to 2.77), deltoid muscles (98 kPa, 45 to 149; d: 1.34, 0.62 to 2.04; 75 kPa 18 to 132; d: 1.12, 0.27 to 1.96), second metacarpal (93 kPa, 45 to 134; d: 1.30, 0.63 to 1.86; 99 kPa 59 to 139; d: 1.60, 0.96 to 2.24), and tibialis anterior muscles (71 kPa, 40 to 144; d: 1.16, 0.65 to 2.34; 118 kPa 57 to 178; d: 1.17, 0.56 to 1.77). Finally, patients within the CUIDATE program showed a greater reduction of active muscle TrPs compared with the CONTROL group (P<0.01). Conclusions: An 8-week multidimensional program including strengthening exercises, and massage as major components was effective for improving neck and shoulder pain and reducing widespread pressure hyperalgesia in breast cancer survivors compared with usual care treatment. © 2012 by Lippincott Williams & Wilkins.

Background: Anthracyclines and taxanes have been the standard neoadjuvant chemotherapies for breast cancer in the past decade. We aimed to assess safety and efficacy of the addition of gemcitabine to accelerated paclitaxel with epirubicin and cyclophosphamide, and also the effect of sequencing the blocks of epirubicin and cyclophosphamide and paclitaxel (with or without gemcitabine). Methods: In our randomised, open-label, 2×2 factorial phase 3 trial (Neo-tAnGo), we enrolled women (aged >18 years) with newly diagnosed breast cancer (tumour size >20 mm) at 57 centres in the UK. Patients were randomly assigned via a central randomisation procedure to epirubicin and cyclophosphamide then paclitaxel (with or without gemcitabine) or paclitaxel (with or without gemcitabine) then epirubicin and cyclophosphamide. Four cycles of each component were given. The primary endpoint was pathological complete response (pCR), defined as absence of invasive cancer in the breast and axillary lymph nodes. This study is registered with EudraCT (2004-002356-34), ISRCTN (78234870), and ClinicalTrials.gov (NCT00070278). Findings: Between Jan 18, 2005, and Sept 28, 2007, we randomly allocated 831 participants; 207 received epirubicin and cyclophosphamide then paclitaxel; 208 were given paclitaxel then epirubicin and cyclophosphamide; 208 had epirubicin and cyclophosphamide followed by paclitaxel and gemcitabine; and 208 received paclitaxel and gemcitabine then epirubicin and cyclophosphamide. 828 patients were eligible for analysis. Median follow-up was 47 months (IQR 37-51). 207 (25%) patients had inflammatory or locally advanced disease, 169 (20%) patients had tumours larger than 50 mm, 413 (50%) patients had clinical involvement of axillary nodes, 276 (33%) patients had oestrogen receptor (ER)-negative disease, and 191 (27%) patients had HER2-positive disease. Addition of gemcitabine did not increase pCR: 70 (17%, 95% CI 14-21) of 404 patients in the epirubicin and cyclophosphamide then paclitaxel group achieved pCR compared with 71 (17%, 14-21) of 408 patients who received additional gemcitabine (p=0·98). Receipt of a taxane before anthracycline was associated with improved pCR: 82 (20%, 95% CI 16-24) of 406 patients who received paclitaxel with or without gemcitabine followed by epirubicin and cyclophosphamide achieved pCR compared with 59 (15%, 11-18) of 406 patients who received epirubicin and cyclophosphamide first (p=0·03). Grade 3 toxicities were reported at expected levels: 173 (21%) of 812 patients who received treatment and had full treatment details had grade 3 neutropenia, 66 (8%) had infection, 41 (5%) had fatigue, 41 (5%) had muscle and joint pains, 37 (5%) had nausea, 36 (4%) had vomiting, 34 (4%) had neuropathy, 23 (3%) had transaminitis, 16 (2%) had acute hypersensitivity, and 20 (2%) had a rash. 86 (11%) patients had grade 4 neutropenia and 3 (<1%) had grade 4 infection. Interpretation: Although addition of gemcitabine to paclitaxel and epirubicin and cyclophosphamide chemotherapy does not improve pCR, sequencing chemotherapy so that taxanes are received before anthracyclines could improve pCR in standard neoadjuvant chemotherapy for breast cancer.
