Pegylated liposomal doxorubicin plus cyclophosphamide followed by paclitaxel as primary chemotherapy in elderly or cardiotoxicity-prone patients with high-risk breast cancer: results of the phase II CAPRICE study.

Anthracycline and taxane-based primary chemotherapy (PCT) is the standard treatment for high-risk breast cancer (HRBC). However, conventional anthracyclines are not commonly used in elderly patients or those prone to cardiotoxicity. Pegylated liposomal doxorubicin, (PLD) has comparable efficacy, but less cardiotoxicity than conventional anthracyclines. We conducted a phase II single-arm trial to assess the efficacy and safety of PCT based on PLD followed by paclitaxel (PTX) in a HRBC population usually undertreated. Fifty patients with stage II-IIIB breast cancer and at least one risk factor for developing cardiotoxicity initiated PLD 35 mg/m(2) plus cyclophosphamide 600 mg/m(2) every 4 weeks for four cycles, followed by 80 mg/m(2) weekly PTX for 12. Close cardiac monitoring was performed. Primary endpoint was the pathological complete response rate (pCR) in the breast. Treatment delivery and toxicities were assessed. Eighty-four per cent of patients were older than 65 years, 64 % suffered from hypertension, and 10 % had prior cardiac disease. In an intention-to-treat analysis, breast pCR was 32 % (95 % CI 19.5-46.7 %) and pCR in breast and axilla was 24 % (95 % CI 12.1-35.8 %). At diagnosis only, 26 % of patients were candidates for breast conservative surgery, which increased to 58.7 % after PCT. No significant decrease in left ventricular ejection fraction was seen. PLD followed by PTX was feasible in a fragile population of patients who were not candidates for conventional doxorubicin. Moreover, it achieved a pCR similar to standard therapy and could therefore be an option for elderly patients or cardiotoxicity-prone who present HRBC.

Phase III trial of nonpegylated liposomal doxorubicin in combination with trastuzumab and paclitaxel in HER2-positive metastatic breast cancer.

BACKGROUND: Nonpegylated liposomal doxorubicin liposomal doxorubicin, (Myocet™; Sopherion Therapeutics, Inc Canada, and Cephalon, Europe) (NPLD; Myocet(®)) in combination with trastuzumabHerceptin(®) (Hoffmann-La Roche) has shown promising activity and cardiac safety. We conducted a randomized phase III trial of first-line NPLD plus trastuzumab and paclitaxel (Pharmachemie B.V.) (MTP) versus trastuzumab plus paclitaxel (TP) in patients with human epidermal growth factor 2 receptor (HER2)-positive metastatic breast cancer. PATIENTS AND METHODS: Patients were randomly assigned to NPLD (M, 50 mg/m(2) every 3 weeks for six cycles), trastuzumab (T, 4 mg/kg loading dose followed by 2 mg/kg weekly), and paclitaxel (P, 80 mg/m(2) weekly) or T + P at the same doses until progression or toxicity. The primary efficacy outcome was progression-free survival (PFS). RESULTS: One hundred and eighty-one patients were allocated to receive MTP, and 183 to TP. Median PFS was 16.1 and 14.5 months with MTP and TP, respectively [hazard ratio (HR) 0.84; two-sided P = 0.174]. In patients with estrogen receptor (ER)- and progesterone receptor (PR)-negative tumors, PFS was 20.7 and 14.0 months, respectively [HR 0.68; 95% confidence interval (CI) 0.47-0.99]. Median overall survival (OS) was 33.6 and 28.9 months with MTP and TP, respectively (HR 0.79; two-sided P = 0.083). In ER- and PR-negative tumors, OS was 38.2 and 27.9 months, respectively (HR 0.63; 95% CI 0.42-0.93). The frequency of adverse events was higher with MTP, but there was no significant difference in cardiac toxicity between treatment arms. CONCLUSION(S): The trial failed to demonstrate a significant clinical improvement with the addition of M to TP regimen. The clinical benefit observed in an exploratory analysis in the ER- and PR-negative population deserves consideration for further clinical trials. CLINICAL TRIAL NUMBER: NCT00294996.

Present and future breast cancer management--bench to bedside and back: a positioning paper of academia, regulatory authorities and pharmaceutical industry.

Insights into tumour biology of breast cancer have led the path towards the introduction of targeted treatment approaches; still, breast cancer-related mortality remains relatively high. Efforts in the field of basic research revealed new druggable targets which now await validation within the context of clinical trials. Therefore, questions concerning the optimal design of future studies are becoming even more pertinent. Aspects such as the ideal end point, availability of predictive markers to identify the optimal cohort for drug testing, or potential mechanisms of resistance need to be resolved. An expert panel representing the academic community, the pharmaceutical industry, as well as European Regulatory Authorities met in Vienna, Austria, in November 2012, in order to discuss breast cancer biology, identification of novel biological targets and optimal drug development with the aim of treatment individualization. This article summarizes statements and perspectives provided by the meeting participants.

Zoledronic acid (zoledronate) for postmenopausal women with early breast cancer receiving adjuvant letrozole (ZO-FAST study): final 60-month results.

BACKGROUND: Aromatase inhibitors are the preferred adjuvant endocrine therapy for the majority of postmenopausal women with hormone-responsive early breast cancer. Although generally more effective than tamoxifen, aromatase inhibitor therapy is associated with increased bone loss and fracture risk. PATIENTS AND METHODS: Postmenopausal women receiving adjuvant letrozole (2.5 mg/day for 5 years; N = 1065) were randomly assigned to immediate zoledronic acid (zoledronate) 4 mg every 6 months for 5 years, or delayed zoledronate (initiated for fracture or on-study bone mineral density [BMD] decrease). The primary end point was the change in lumbar spine BMD at 12 months. Lumbar spine and total hip BMD at subsequent follow-up, disease-free survival (DFS), and overall survival were assessed as secondary end points. RESULTS: At 60 months (final analysis), the mean change in lumbar spine BMD was +4.3% with immediate zoledronate and -5.4% with delayed intervention (P < 0.0001). Immediate zoledronate reduced the risk of DFS events by 34% (hazard ratio [HR] = 0.66; P = 0.0375) with fewer local (0.9% versus 2.3%) and distant (5.5% versus 7.7%) recurrences versus delayed zoledronate. In the delayed group, delayed initiation of zoledronate substantially improved DFS versus no zoledronate (HR = 0.46; P = 0.0334). CONCLUSIONS: Immediate zoledronate in postmenopausal women receiving letrozole preserved BMD and is associated with improved DFS compared with letrozole alone. Clinical Trials Registration No NCT00171340.

Adverse events risk associated with bevacizumab addition to breast cancer chemotherapy: a meta-analysis.

BACKGROUND: Bevacizumab is a monoclonal antibody against vascular endothelial growth factor with the ability to increase progression-free survival in metastatic breast cancer (MBC). A systematic review and meta-analysis was conducted to determine the risk of the most clinically relevant adverse outcomes associated with the use of bevacizumab in the treatment of breast cancer. PATIENTS AND METHODS: We included phase III clinical trials that used bevacizumab alone or in combination with chemotherapy as for MBC or locally recurrent. Statistical analyses were conducted to calculate summary odds ratio (OR) of the eight most relevant adverse outcomes related with bevacizumab. RESULTS: Five clinical trials were included in the meta-analysis. Summary odds ratios obtained showed a statistically significant bevacizumab-associated increased risk in four of the adverse outcomes studied: proteinuria (OR = 27.68), hypertension (OR = 12.76), left ventricular dysfunction (LVD) (OR = 2.25), and hemorrhagic events (OR = 4.07). No statistically significant differences were found for gastrointestinal (GI) perforation, vascular events, fatal events, or febrile neutropenia. CONCLUSIONS: Bevacizumab did increase the risk of LVD and hemorrhagic events. The addition of bevacizumab to chemotherapy in patients with metastatic breast cancer was not associated with a significant increase in grade ≥ 3 arterial or venous thromboembolic events, GI perforation, or fatal events.

Capecitabine and bevacizumab as first-line treatment in elderly patients with metastatic colorectal cancer.

BACKGROUND: The efficacy and safety of capecitabine and bevacizumab in elderly patients with metastatic colorectal cancer (mCRC) considered unsuitable for receiving first-line chemotherapy with an irinotecan or oxaliplatin-based combination were assessed in a phase II, open, multicentre, uncontrolled study. METHODS: Treatment consisted of capecitabine 1250 mg m(-2) (or 950 mg m(-2) for patients with a creatinine clearance of 30-50 ml min(-1)) twice daily on days 1-14 and bevacizumab (7.5 mg kg(-1)) on day 1 every 3 weeks. RESULTS: A total of 59 patients aged >or=70 years with mCRC were enrolled. In an intention-to-treat analysis, the overall response rate was 34%, with 71% of patients achieving disease control. Median progression-free survival and overall survival were 10.8 months and 18 months, respectively. In all, 32 patients (54%) had grade 3/4 adverse events (AEs), the most common being hand-foot syndrome (19%), diarrhoea (9%) and deep venous thrombosis (7%). Four patients died because of treatment-related AEs. A relationship was detected between creatinine clearance

Real-world data on the efficacy and safety of weekly oral vinorelbine in breast cancer patients previously treated with anthracycline or taxane-based regimens.

PURPOSE: To evaluate the efficacy and safety of oral weekly vinorelbine 60 mg/m2 for metastatic breast cancer (MBC) in patients previously treated with anthracyclines or taxanes in routine clinical practice. MATERIALS AND METHODS: Fifty-five patients were enrolled in a prospective multicentre study conducted in Spain. Women ≥ 18 years of age with locally advanced breast cancer who were not candidates for surgical treatment with a radical intention or patients with stage IV disease, and who had received a prior taxane or anthracycline regimen were eligible for participation. RESULTS: Median age was 67 years. Median progression-free survival was 3.7 months (95% CI 2.5-4.9), median overall survival 10 months (95% CI 6.6-13.5), and overall response rate and clinical benefit rate were 29.1% and 49.1%, respectively. Main grade 3 and 4 toxicities were neutropenia 9.1%, febrile neutropenia 3.6% and constipation 3.6%. In total, 86% of the patients received complete treatment without delays or dose reduction. Moreover, HER2-positive patients who received oral vinorelbine concomitantly with trastuzumab showed better response (complete response: HER2-positive 14.3% vs. HER2-negative 0%; partial response: HER2-positive 42.9% vs. HER2-negative 25.6%; p = 0.008), better disease control rate (HER2-positive 100% vs. HER2-negative 46.2%; p = 0.011), and better values for the remaining analysed variables than HER2-negative patients. CONCLUSION: Our study provides real-world data on the use of oral weekly vinorelbine, which proves an effective and well-tolerated regimen for MBC patients previously treated with taxanes or anthracyclines. Patients with HER2-positive disease could also benefit from this treatment in combination with trastuzumab.

Evolution of older patients diagnosed with early breast cancer in Spain between 1998 and 2001 included in El Alamo III project.

INTRODUCTION: An increase in the number of cancer cases is expected in the near future. Breast cancer (BC) mortality rates increase with age even when adjusted for other variables. Here we analyzed BC disease-free survival (BCDFS) and BC specific survival (BCSS) in the El Alamo III BC registry of GEICAM Spanish Breast Cancer Group. MATERIALS AND METHODS: El Alamo III is a retrospective registry of BC patients diagnosed between 1998 and 2001. Patients with stage I-III invasive BC of age groups 55-64 years (y), 70-74 years and ≥ 75 years were included. Patients and tumors characteristics, treatments and recurrences and deaths were analyzed. RESULTS: 4343 patients were included within the following age intervals: 2288 (55-64 years), 960 (70-74 years), and 1095 (≥ 75 years). Older patients (≥ 70 years) were diagnosed with more advanced tumors (stage III) than younger patients (21.5% versus 13.4%, p < 0.0001). Mastectomies were performed more on older patients and they received less chemotherapy than younger patients (66.6% versus 43.1%, p < 0.00001 and 30.8% versus 71.6%, p < 0.0001, respectively). With a median follow-up of 5.9 years, 17.7% patients had BCDFS events in the younger group and 19.8% in the older group (p < 0.0001). A decrease in BCSS was also observed in older patients, either when analyzing patients ≥ 70y (p < 0.0001) and when differentiating by the two older groups (p < 0.0001). CONCLUSIONS: Our study suggests that older BC patients have worse outcomes what can be a consequence of receiving inadequate adjuvant treatments. Specific trials for these patients are warranted to allow us to treat them with the same scientific rigor than younger patients.

BOMET-QoL-10 questionnaire for breast cancer patients with bone metastasis: the prospective MABOMET GEICAM study.

BACKGROUND: Bone metastasis (BM) is the most common site of disease in metastatic breast cancer (MBC) patients. BM impacts health-related quality of life (HRQoL). We tested prospectively the psychometric properties of the Bone Metastasis Quality of Life (BOMET-QoL-10) measure on MBC patients with BM. METHODS: Patients completed the BOMET-QoL-10 questionnaire, the Visual Analogue Scale (VAS) for pain, and a self-perceived health status item at baseline and at follow-up visits. We performed psychometric tests and calculated the effect size of specific BM treatment on patients´ HRQoL. RESULTS: Almost 70% of the 172 patients reported symptoms, 23.3% experienced irruptive pain, and over half were receiving chemotherapy. BOMET-QoL-10 proved to be a quick assessment tool performing well in readability and completion time (about 10 min) with 0-1.2% of missing/invalid data. Although BOMET-QoL-10 scores remained fairly stable during study visits, differences were observed for patient subgroups (e.g., with or without skeletal-related events or adverse effects). Scores were significantly correlated with physician-reported patient status, patient-reported pain, symptoms, and perceived health status. BOMET-QoL-10 scores also varied prospectively according to changes in pain intensity. CONCLUSIONS: BOMET-QoL-10 performed well as a brief, easy-to-administer, useful, and sensitive HRQoL measure for potential use for clinical practice with MBC patients. TRIAL REGISTRATION: NCT03847220. Retrospectively registered on clinicaltrials.gov (February the 20th 2019).

Current controversies in the management of early breast cancer.

Medical professionals in general, and medical oncologists in particular, have highly stressful practices because they are under constant pressure to have the highest-quality, up-to-date evidence available in order to make the right decision for each individual patient. From a practical point of view, being updated on oncological and other medical specialties may seem an insurmountable task because the number of scientific publications has increased dramatically. The use of systematic reviews of randomised controlled trials or the application of results obtained from high-quality randomised controlled trials are some of the most common ways to address this need. Unfortunately, they do not cover all complex clinical situations that the majority of medical oncologists face in their outpatient consultations. In this review, we report the conclusions achieved in a multiexpert meeting where five important controversies in the treatment of breast cancer were analysed. Five highly experienced medical oncologists were required to defend an affirmative answer and another five were required to defend a negative answer for each of the clinical questions. After that, a one-day meeting was organised to debate each clinical question and to reach a consensus. We report here the content of this multi-expert meeting along with the conclusions drawn.

Medical oncology future plan of the Spanish Society of Medical Oncology: challenges and future needs of the Spanish oncologists.

PURPOSE: The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. METHODS: The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. RESULTS: A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. CONCLUSIONS: Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.

A definition for aggressive disease in patients with HER-2 negative metastatic breast cancer: an expert consensus of the Spanish Society of Medical Oncology (SEOM).

PURPOSE: To converge on an expert opinion to define aggressive disease in patients with HER2-negative mBC using a modified Delphi methodology. METHODS: A panel of 21 breast cancer experts from the Spanish Society of Medical Oncology agreed upon a survey which comprised 47 questions that were grouped into three sections: relevance for defining aggressive disease, aggressive disease criteria and therapeutic goals. Answers were rated using a 9-point Likert scale of relevance or agreement. RESULTS: Among the 88 oncologists that were invited to participate, 81 answered the first round (92%), 70 answered the second round (80%), and 67 answered the third round (76%) of the survey. There was strong agreement regarding the fact that identifying patients with aggressive disease needs to be adequately addressed to help practitioners to decide the best treatment options for patients with HER2-negative mBC. The factors that were considered to be strongly relevant to classifying patients with aggressive HER2-negative mBC were a high tumor burden, a disease-free interval of less than 12-24 months after surgery, the presence of progressive disease during adjuvant or neoadjuvant chemotherapy and having a triple-negative phenotype. The main therapeutic goals were controlling symptoms, improving quality of life and increasing the time to progression and overall survival. CONCLUSIONS: High tumor burden, time to recurrence after prior therapy and having a triple-negative phenotype were the prognostic factors for which the greatest consensus was found for identifying patients with aggressive HER2-negative mBC. Identifying patients with aggressive disease leads to different therapeutic approaches.

Paclitaxel/gemcitabine administered every two weeks in advanced breast cancer: preliminary results of a phase II trial.

The purpose of this study was to evaluate the toxicity and efficacy of paclitaxel/gemcitabine administered every 2 weeks in the first-line treatment of advanced breast cancer. Forty-three chemonaive patients with histologically confirmed metastatic breast carcinoma were enrolled. Patients received paclitaxel 150 mg/m2 followed by gemcitabine 2,500 mg/m2, both on day I of a 14-day cycle, for a maximum of eight cycles. Thirty-four patients were evaluable for toxicity; 38 were evaluable for efficacy. The median age at the time of diagnosis was 54 years, the median performance status was 90, and the median number of lesions was three. Most patients (71%) had received prior adjuvant therapy. Grade 3 and 4 toxicity was limited to leukocytes (14% and 18%, respectively). Grade 3 toxicities (5% each) were thrombocytopenia, nausea and vomiting, elevation of aspartate transaminase, neurosensory, and constipation. One patient had neutropenia and fever. The objective response rate was 68% (21% complete response and 47% partial response); 18% had stable disease and 13% had partial disease. The preliminary evaluation of paclitaxel/gemcitabine given as a 2-week schedule to patients with untreated advanced breast carcinoma shows encouraging activity and a favorable toxicity profile.

Ovarian sex cord tumor with annular tubules in a woman with premature ovarian failure.

OBJECTIVE: To report a case of premature ovarian failure (POF) associated with an ovarian sex cord tumor with annular tubules. DESIGN: Case report. SETTING: Reproductive endocrinology unit in a tertiary academic center. PATIENT(S): A 20-year-old woman with POF. INTERVENTION(S): Biopsy of the rudimentary ovary by laparoscopy. MAIN OUTCOME MEASURE(S): Protocol for POF investigation and histological study of the ovarian sample. RESULT(S): An ovarian sex cord tumor with annular tubules was detected in the rudimentary right ovary. CONCLUSION(S): The rare ovarian sex cord tumor with annular tubules, which may be hormonally active, was detected in a case of POF.

Treatment with a nonanthracycline regimen in advanced breast cancer: vinorelbine, cyclophosphamide, and 5-fluorouracil with folinic acid.

The efficacy of combination therapy with vinorelbine, cyclophosphamide, and 5-fluorouracil was assessed in women who had received no prior therapy for locally advanced or metastatic breast cancer. Sixty patients with metastatic breast cancer who had finished any adjuvant therapy at least 6 months previously and who had not received treatment for advanced disease were entered onto the study. The schedule consisted of vinorelbine (Navelbine, Pierre Fabre Medicament) 25 mg/m2 on days 1 and 8, cyclophosphamide 500 mg/m2 on day 1, and 5-fluorouracil 500 mg/m2 followed by folinic acid 200 mg/m2 on days 1 and 8. Treatment was repeated every 21 days up to a maximum of 8 cycles. Objective responses were observed in 27 of 60 patients (45%; CI95 32.4-57.6) including 4 complete responses (6.7%; CI95 0-13) and 23 partial responses (38.3%; CI95 22.5-54.1). The responses were achieved in both visceral and nonvisceral sites and at the same rate for patients with multiple sites of disease. Neutropenia was dose limiting, with 40% of patients affected at grade 3 or 4, while other hematologic and nonhematologic toxicity was very mild. This schedule achieves good levels of response without the use of an anthracycline, so it is suitable either for patients who have been extensively exposed to anthracyclines during adjuvant therapy or for those who have other contraindications to their use.

[Angiosarcoma of the breast. Apropos of 8 cases and review of the literature]. / Les angiosarcomes du sein. Etude de 8 cas et revue de la littérature.

The 8 cases of primary breast angiosarcoma which were diagnosed, treated and had their follow-up at the Gustave-Roussy Institute between 1954 and 1995 are reported. The age at presentation ranged from 32 to 68 years. In 4 patients the vascular nature of their mammary lesion was conspicuous by a violaceous discolorations of the overlying skin. No patient had enlarged ipsilateral axillary lymph nodes. One patient had metastases. In 2 out of 5 patients who had a partial surgical or fine-needle biopsy before treatment, the diagnosis was missed, and adequate treatment was unduly delayed. The tumor most often presents as an ill defined area made of dense endothelium-lined papillae. A remarkable picture of "soap bubbles" has been identified in 4 cases. The "meshes" of fatty areas appear to be reinforced as they are infiltrated by tumor cells. This appearance may be specific of mammary angiosarcoma. By the French Cancer Centers' grading system for soft tissue sarcomas in general, grade is III in 3 tumors, II in 2 tumors, I in 3 tumors. Five tumors were treated by total mastectomy only. In 3 cases a total mastectomy was followed by radiation therapy to the chest wall. At diagnosis a chemotherapy was administered only to the patient who had metastases. Median disease-free survival was 9 months. Median overall survival was 13 months. From a review of the literature a simple mastectomy appears to be necessary as well as enough for local treatment. Patients with a grade III angiosarcoma of the breast should be included into a therapeutical trial of adjuvant chemotherapy for soft tissue sarcomas in general.
