Value of a short-term imaging follow-up after a benign result in a one-stop breast unit: Is it still useful?

INTRODUCTION: A short-term radiologic follow-up after a benign breast biopsy or fine needle aspiration (FNA) is recommended in many guidelines. However, the current trend is to reduce imaging investigations, radiation dose and costs. The objectives of this study were to evaluate the cancer detection rate at short-term follow-up and to estimate its cost. METHODS: We retrospectively assessed all consecutive patients referred to our 'one-stop' breast unit between 2004 and 2012, with a benign histological or cytological result and at least one short-term follow-up within 3-12 months after the initial diagnosis. We evaluated the number of cancers detected, as well as the mean cost to detect each cancer and per patient. RESULTS: About 1366 patients were eligible for this study. Ten patients were diagnosed with cancers (0.73%) at short-term follow-up; six of 10 were low-grade tumours or ductal carcinoma in situ. The cost for detecting one cancer was 19,043€, with mean cost per patient of 139€. CONCLUSION: The cancer detection rate at short-term follow-up after benign biopsy or FNA was low and was similar to that of most national screening programs. The cost of cancer detection appeared high, considering that most cancers were indolent. This suggests that radiologic follow-up could reasonably be carried out at a later point in time.

Comparison of the Explantation Rate of Poly Implant Prothèse, Allergan, and Pérouse Silicone Breast Implants within the First Four Years after Reconstructive Surgery before the Poly Implant Prothèse Alert by the French Regulatory Authority.

Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament), the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP) breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof) of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France). The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse) were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%), infection (22.2%), and capsular contracture (13.6%). Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

Exploring frontiers: use of complementary and alternative medicine among patients with early-stage breast cancer.

INTRODUCTION: Complementary and alternative medicine (CAM) is increasingly popular among cancer patients but can interfere with conventional therapies; timely data are needed to adapt current patients' care. MATERIALS AND METHODS: This transversal, prospective study evaluated the use of CAM among patients receiving adjuvant chemotherapy or endocrine therapy for early stage breast cancer. We assessed the prevalence of use, the motivations and predictive factors for use, as well as patients' information needs over a three months period. RESULTS: 69/184 responders (37.5%) reported using at least one CAM. CAM use was associated with younger age (p = 0.03) and higher education level (p < 0.001). Pharmacological substances (e.g., homeopathy, phytotherapy) were the most commonly used (79.7%) before physical means (42%) and dietary methods (31.9%). A total of 65.8% of users felt that these treatments have demonstrated evidence of efficacy and 74.8% that they were not associated with side effects. The main goal for use was improvement of treatment-related symptoms (28.3%); secondary goal was increasing the general health status (20.5%). Patients reported high needs for information on CAMs. CAM use was associated with mild differences in secondary adverse events reported by patients. CONCLUSION: Breast cancer patients are common users of CAM concomitantly to their conventional cancer treatments and should be investigated regarding their current consumption of CAM. Furthermore, they need advice evidence-based data on these treatments and potential interactions with on-going treatments.

Decision-making from multidisciplinary team meetings to the bedside: factors influencing the recruitment of breast cancer patients into clinical trials.

AIM OF THE STUDY: Our aim was to determine factors influencing physicians and breast cancer patients to respectively propose or accept participation in a clinical trial following proposals made during a multidisciplinary team meeting (MTM) in a Comprehensive Cancer Centre. PATIENTS AND METHODS: Consecutive patients considered eligible for a clinical trial by a breast cancer-specific MTM were included. A detailed analysis of factors predictive of the physician proposing the trial and the patient's acceptance and final inclusion was conducted. RESULTS: MTM proposed 547 inclusions in 25 clinical trials for 397 patients between March and September 2011. The physician proposed the scheduled clinical trial in only 39% of the cases. The patients accepted the proposal in 74% of the cases, and finally 29% were included. The main reason for non-inclusion was the physician's failure to propose the trial in 45-81%, depending on the type of study. The only factor predictive of both the physician proposing the trial and final inclusion was the type of study (both p < 0.001). Diagnostic/prognostic studies were the most frequently proposed trials. The professional status (of the subject) was predictive of acceptance (p = 0.03) with higher rates among retired patients and executives (84 and 76% respectively). CONCLUSION: The major reason for non-inclusion in clinical trials was the physician's failure to propose the trial, while the patient's professional status and the type of study influenced both physicians and patients. Educative measures mostly directed at physicians could be implemented to overcome such poor compliance.

A pre-operative nomogram for decision making in oncological surgical emergencies.

BACKGROUND: The purpose of the study was to propose a clinical decision-making tool for predicting mortality in patients undergoing emergency abdominal surgery with a palliative intent in the oncology setting. METHODS: Identification of all emergency surgical procedures performed in a Department of Oncologic Surgery in a Comprehensive Cancer Center between January 2008 and January 2013. Multivariate logistic and Cox regression models were used to identify factors predicitve of mortality at 3 months and survival probabilities. Models were internally validated using bootstrapping and calibration. RESULTS: The mortality rates were 30% at 1 month, 46.7% at 3 months and 83.3% at the end of the study. One model based on the albumin level and the P-POSSUM score (AUC: 0.725) adequately predicted mortality at 3 months. A survival nomogram predicted mortality with a concordance index (CI) of 0.718, using the following factors: WHO performance status (P = 0.02), albumin level (P < 0.01) and P-POSSUM score (P < 0.01). The origin or the extent of the carcinoma did not own sufficient pronostic impact to be selected in this model. CONCLUSIONS: Pre-operative mortality risk scores can be developed in a palliative context. Physicians counselling and surgical decision making should be based on the use of these tools.

The role of oncoplastic breast surgery in the management of breast cancer treated with primary chemotherapy.

OBJECTIVE: The purpose of this study was to evaluate the benefit of Oncoplastic Breast Conserving Surgery (BCS) compared to standard BCS after primary CT, in terms of oncologic safety and cosmetic outcomes. BACKGROUND: The development of new drugs has led to greater use of primary chemotherapy (CT) for bulky breast cancer (BC) and has allowed wider indications for conservative surgery. PATIENTS AND METHODS: We identified 259 patients consecutively treated with BCS for primary BC from January 2002 to November 2010. All patients had undergone Oncoplastic Breast Surgery (OBS) or standard BCS after primary CT. Mastectomy rates, and oncological and cosmetic outcomes were compared. RESULTS: A total of 45 OBS and 214 standard BCS were analyzed. The median tumor size was 40 mm in the two groups (p = 0.66). The median operative specimen volumes were larger in the OBS group than in the standard group (respectively, 180 cm3 and 98 cm3, p < 0.0001). Re-excision (9% vs. 2%) and mastectomy (24% vs. 18%) rates were similar (p = 0.22 and p = 0.30) in the standard BCS group and in the OBS group respectively. At a median follow-up of 46 months, local relapse (p = 0.23) and distant relapse (p = 0.35) rates were similar. CONCLUSION: OBS allows excision of larger volumes of residual tumor after primary CT. OBS outcomes results were similar to those of standard BCS. Oncoplastic Breast Conserving Surgery (BCS) after primary chemotherapy allows wider breast resection than standard BCS. Survival and relapse probabilities are similar in both groups.

Cyclophosphamide dose intensification may circumvent anthracycline resistance of p53 mutant breast cancers.

The predictive value of p53 for the efficacy of front-line anthracycline-based chemotherapy regimens has been a matter of significant controversy. Anthracyclines are usually combined with widely different doses of alkylating agents, which may significantly modulate tumor response to these combinations. We analyzed three series of de novo stage II-III breast cancer patients treated front line with anthracycline-based regimens of various cyclophosphamide dose intensities: 65 patients with estrogen receptor (ER)(-) tumors treated with anthracyclines alone (Institut Jules Bordet, Brussels), 51 unselected breast cancer patients treated with intermediate doses of cyclophosphamide (MD Anderson Cancer Center, Houston, TX), and 128 others treated with a dose-dense anthracycline-cyclophosphamide combination (St. Louis, Paris). After chemotherapy and surgery, pathologic complete response (pCR) was evaluated. p53 status was determined by a yeast functional assay on the pretreatment tumor sample. In a multivariate analysis of the pooled results, a lack of ER expression and high-dose cyclophosphamide administration were associated with a higher likelihood of pCR. A sharp statistical interaction was detected between p53 status and cyclophosphamide dose intensity. Indeed, when restricting our analysis to patients with ER(-) tumors, we confirmed that a mutant p53 status was associated with anthracycline resistance, but found that p53 inactivation was required for response to the dose-intense alkylating regimen. The latter allowed very high levels of pCR in triple-negative tumors. Thus, our data strongly suggest that cyclophosphamide dose intensification in ER(-) p53-mutated breast cancer patients could significantly improve their response.
