Background. The Hermine study observed the use of trastuzumab for metastatic breast cancer (MBC) in routine practice, including patients who received trastuzumab treatment beyond progression (TBP). Patients and Methods. The study observed 623 patients for ≥2 years. Treatment was given according to oncologists' normal clinical practices. Endpoints included duration of treatment, efficacy, and cardiac safety. The TBP subanalysis compared overall survival (OS) in 177 patients who received first-line trastuzumab and either continued trastuzumab for ≥30 days following progression or stopped at or before progression. Results. The median treatment duration was 13.3 months. In the first-, second-, and third-line or beyond treatment groups, the median time to progression (TTP) were 10.3 months, 9.0 months, and 6.3 months, and the median OS times were 30.3 months, 27.1 months, and 23.2 months, respectively. Heart failure was observed in 2.6% of patients, although no cardiacassociated deaths occurred. In the TBP subanalysis, the median OS duration from treatment initiation and time of disease progression were longer in patients who continued receiving trastuzumab TBP (>27.8 months and 21.3 months, respectively) than in those who stopped (16.8 months and 4.6 months, respectively). However, the groups were not completely comparable, because patients who continued trastuzumab TBP had better prognoses at treatment initiation. The median TTP was longer in patients who continued trastuzumab TBP (10.2 months) than in those who stopped (7.1 months). Conclusion. The Hermine findings confirm that the pivotal trials of first-line trastuzumab treatment in MBC patients are applicable in clinical practice. The subanalysis suggests that trastuzumab TBP offers a survival benefit to MBC patients treated with first-line trastuzumab. © AlphaMed Press. Source

Breast Cancer Research and Treatment | Year: 2010
The objective is to prospectively determine the factors responsible for reconstruction failure and capsular contracture in mastectomized breast cancer patients who underwent immediate two-stage breast reconstruction with a tissue expander and implant, followed by radiotherapy. This is a multicenter, prospective, non-randomized study. Between February 1998 and September 2006, we prospectively examined 141 consecutive patients, each of which received an implant after mastectomy, followed by chest wall radiotherapy at 46-50 Gy in 23-25 fractions. Radiotherapy was delivered during immediate post-mastectomy reconstruction. Patients were evaluated by both a radiation oncologist and a surgeon 24-36 months after treatment. The median follow-up duration was 37 months. According to Baker's classification, capsular contracture was grade 0, 1, or 2 in 67.5% of cases; it was grade 3 or 4 in 32.5% of cases. In total, 32 breast reconstruction failures required surgery. In univariate analysis, the following factors were associated with Baker grade 3 and 4 capsular contraction: adjuvant hormone therapy (P = 0.02), the surgeon (P = 0.04), and smoking (P = 0.05). Only one factor was significant in multivariate analysis: the surgeon (P = 0.009). Three factors were associated with immediate post-mastectomy breast reconstruction failure in multiple logistic regression analysis: T3 or T4 tumors (P = 0.0005), smoking (P = 0.001), and pN+ axillary status (P = 0.004). Patients with none, 1, 2, or all 3 factors have a probability of failure equal to 7, 15.7, 48.3, and 100%, respectively (P = 3.6 x 10-6). The model accurately predicts 80% of failures. Mastectomy, immediate reconstruction (expander followed by implant), and radiotherapy should be considered when conservative surgery is contraindicated. Three factors may be used to select patients likely to benefit from this technique with a low failure rate. © Springer Science+Business Media, LLC. 2009. Source

Background: Platinum rechallenge or weekly topotecan in combination have not been evaluated in randomized trials for resistant recurrent ovarian cancer (ROC). Methods: Patients with ROC after first- or second-line treatment including a platinum and taxane and progression within 6 months were randomized to weekly paclitaxel (wP, 80 mg/m. 2/week) alone or in combination with carboplatin (C, area under the curve of 5 mg/ml/min every 4 weeks) or weekly topotecan (wT, 3 mg/m 2/week). Primary end point was progression-free survival (PFS) comparing wP and combination therapy. Results: Patients (n = 165) received a median three cycles in each arm. Nonhematologic toxicity was not different, except increased hypersensitivity reactions with wP + C. Grade 3-4 hematologic toxic effects with wP, wP + C, and wP + wT, respectively, were neutropenia in 13%, 54%, and 42%; febrile neutropenia in 0%, 4%, and 5%; and anemia in 6%, 19%, and 29%. Response rates were 35%, 37%, and 39%, and median PFS times were 3.7, 4.8, and 5.4 months, respectively. PFS was not significantly different among the treatment arms [hazard ratio (HR) 0.922; 95% confidence interval (CI) 0.765-1.111; P = 0.46] or between monotherapy and combination therapy (HR 0.951; 95% CI 0.686-1.318; P = 0.76). Conclusions: Combination chemotherapy in platinum-resistant ROC was more toxic than weekly paclitaxel and did not significantly prolong PFS. © The Author 2011.

Critical Reviews in Oncology/Hematology | Year: 2011
Purpose: While new strategies for the treatment of invasive breast cancer (BC) are emerging, radiotherapy (RT) modalities are still under debate. The French expert review board of Nice-Saint-Paul de Vence was asked firstly to conduct a qualitative evidence-based systematic review and then to establish clinical practice guidelines for the use of post operative RT in invasive BC. Methods and materials: A search to identify eligible studies was undertaken using the Medline® database. All phase III randomized trials and systematic reviews evaluating the role and modalities of RT in invasive BC were included, together with some noncontrolled studies if no randomized trials were identified. The quality and clinical relevance of the studies were evaluated to determine the level of evidence. Results: The maximum delay between surgery and RT should ≤8 weeks when chemotherapy (CT) is not indicated. This should not exceed 24 weeks when adjuvant CT is administered. Whole breast RT delivering 50. Gy in 25 fractions followed by a boost of 10-16. Gy remains the standard of care after conservative surgery (CS). In the elderly population, for certain cases presenting comorbidities associated with a limited life expectancy, RT indication (even hypofractioned) and boost delivery may be unnecessary in the light of an unfavourable risk/benefit ratio. RT technique and indications should not vary in case of neoadjuvant CT followed by CS. After total mastectomy, RT should be indicated in N+ and in N- patients with high risk of local recurrence. The experts recommend to initiate tamoxifen at the end of RT, while aromatase inhibitors could be administered either concomitantly or sequentially with RT. There is no consistent data to delay (or suspend) trastuzumab administration during RT. As for all patients, in case of concurrent RT-trastuzumab administration, reduction of cardiac tissues exposure is highly recommended. After breast reconstruction, RT should be delivered as after standard CS without boost. Conclusion: Due to significant variations in practice in the treatment of patients with BC, our group aimed to provide guidelines for clinical practice. The systematic review of the literature formed the basis of our evidence-based recommendations; however expert agreements were necessary on those subjects that are still under debate. Our group will update these guidelines every 4 years, taking in consideration new advances in technology, new drugs administration, biologic tools and innovative therapeutic options. © 2010 Elsevier Ireland Ltd.

Background: The CALYPSO phase III trial compared CD (carboplatin-pegylated liposomal doxorubicin (PLD)) with CP (carboplatin-paclitaxel) in patients with platinum-sensitive recurrent ovarian cancer (ROC). Overall survival (OS) data are now mature.Methods:Women with ROC relapsing 6 months after first-or second-line therapy were randomised to CD or CP for six cycles in this international, open-label, non-inferiority trial. The primary endpoint was progression-free survival. The OS analysis is presented here.Results:A total of 976 patients were randomised (467 to CD and 509 to CP). With a median follow-up of 49 months, no statistically significant difference was observed between arms in OS (hazard ratio0.99 (95% confidence interval 0.85, 1.16); log-rank P=0.94). Median survival times were 30.7 months (CD) and 33.0 months (CP). No statistically significant difference in OS was observed between arms in predetermined subgroups according to age, body mass index, treatment-free interval, measurable disease, number of lines of prior chemotherapy, or performance status. Post-study cross-over was imbalanced between arms, with a greater proportion of patients randomised to CP receiving post-study PLD (68%) than patients randomised to CD receiving post-study paclitaxel (43%; P=0.001).Conclusion:Carboplatin-PLD led to delayed progression and similar OS compared with carboplatin-paclitaxel in platinum-sensitive ROC. © 2012 Cancer Research UK All rights reserved.
