Neoadjuvant chemotherapy in breast cancer: a dose-dense schedule in real life and putative role of PIK3CA mutations. Oncotarget 2018; 9:27380-27396. [PMID: 29937992 PMCID: PMC6007957 DOI: 10.18632/oncotarget.25270] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2017] [Accepted: 04/06/2018] [Indexed: 11/25/2022] Open
Abstract
Background Dose-dense chemotherapy is one of the treatments of choice for neoadjuvant therapy in breast cancer (BC). Activating mutations in PIK3CA gene predict worse response to neoadjuvant chemotherapy for HER2-positive patients, while their role is less clearly defined for HER2-negative tumors. Methods We conducted a phase I/II study of neoadjuvant, sequential, dose-dense anthracycline/taxane chemotherapy, plus trastuzumab in HER2-positive patients and investigated the correlation of pre-treatment PIK3CA mutation status with pathologic complete response (pCR) and long-term outcome in a real-life setting. Results we established a dose-dense docetaxel recommended dose of 60 mg/m2 and 65 mg/m2, with or without trastuzumab, respectively, according to HER2-status, following dose-dense epirubicin-cyclophosphamide (90/600 mg/m2), every 2 weeks. The overall pCR rate was 21.4%; median disease-free survival (DFS) was 52 months and median overall survival (OS) was not yet reached. PIK3CA mutation status was not significantly associated with the pCR rate: 18% for both mutated and wild-type patients. The pCR rate was: 25% in the mutated and 24% in the wild-type (p 0.560) cohort of the HER2-positive subgroup; 33% both in the mutant and wild-type cohort of the triple-negative subgroup; no pCR neither in the mutant nor in the wild-type cohort of the HR-positive/HER2-negative subgroup. Among the HER2-positive population, a trend toward worse DFS was observed in case of mutation, as opposed to the triple negative population. Conclusions This study proposes an effective and safe neoadjuvant dose-dense anthracycline/taxane schedule and suggests that PIK3CA mutation analysis can be usefully performed in real-life clinical practice.

Docetaxel-induced skin toxicities in breast cancer patients subsequent to paclitaxel shortage: a case series and literature review. Support Care Cancer 2013; 21:2679-86. [PMID: 23686402 DOI: 10.1007/s00520-013-1842-3] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2012] [Accepted: 05/07/2013] [Indexed: 10/26/2022]
Abstract
PURPOSE As the result of a recent national shortage in paclitaxel, some patients who were receiving or scheduled to receive weekly paclitaxel were converted to every 3-week (q3w) docetaxel with granulocyte colony-stimulating factor support. Our institution noted higher than expected incidence of severe skin toxicity events attributable to docetaxel during the shortage period among our breast cancer patients. In this report, we summarize the clinical course of the first five cases, review the literature surrounding docetaxel-induced skin toxicity, and offer possible prevention and treatment strategies to improve docetaxel tolerability. METHODS The observation period for this case series was August 1 through October 21, 2011. All patients treated with docetaxel were identified from our electronic medical record. Operable stage I-III breast cancer patients who received ≥ 1 dose of docetaxel monotherapy at 75-100 mg/m(2) q3w were included in this study. The cases of grade 3-4 docetaxel-induced skin toxicities identified by the treating oncologists were then contacted and signed an informed consent through an Institutional Review Board-approved protocol. RESULTS Thirty-four patients met the inclusion criteria. Five patients (14.7 %) experienced grade 3 skin toxicity events attributable to docetaxel, a significantly higher rate than previously reported for docetaxel dosed at 75-100 mg/m(2). CONCLUSIONS Docetaxel-induced dermatologic toxicity is well characterized; nonetheless, its etiology is largely unknown and evidence-based prevention and management strategies are lacking. This report shows that the use of docetaxel 75-100 mg/m(2) q3w subsequent to dose-dense doxorubicin and cyclophosphamide regimen can lead to unacceptable rate of severe skin toxicity.

Abstract
INTRODUCTION The objective was to evaluate a dose-dense schedule of docetaxel followed by doxorubicin and cyclophosphamide (AC) as neoadjuvant treatment for patients with locally advanced breast cancer. PATIENTS AND METHODS Ninety-nine patients were included and received 100 mg/m(2) of docetaxel every two weeks for four cycles followed by 60 mg/m(2) of doxorubicin and 600 mg/m(2) of cyclophosphamide every two weeks for four cycles. Primary prophylaxis with granulocyte colony-stimulating factor (G-CSF) was administered systematically to all patients. RESULTS Efficacy and toxicity analyses were carried out on an intention-to-treat basis. After treatment, complete pathological response in the breast and lymph nodes was confirmed in 15 patients (15%, 95% confidence interval [CI]: 8.4-22.9). Clinical response rate was 74% (95% CI: 65-82), of which 19% were complete responses. Breast-conserving surgery could be performed in 41% of patients. The dose-dense schedule was generally well tolerated. The most important grade 3/4 toxicities per patient were cutaneous toxicity (12.1%) and hepatic dysfunction (9.1%) during docetaxel administration, and neutropenia (28.1%) and leucopenia (8.3%) with AC. CONCLUSION A dose-dense schedule of docetaxel followed by AC as neoadjuvant treatment is an effective and safe treatment for locally advanced breast cancer. Primary prophylaxis with G-CSF, and possibly the change in the sequence of drug administration, appears to play a major role in avoiding the excessive toxicity of dose-dense schedules.

Abstract
INTRODUCTION To evaluate the efficacy and safety profile of the concomitant dose-dense administration of doxorubicin and docetaxel as primary chemotherapy for patients with large or locally advanced breast cancer. MATERIALS AND METHODS Forty-seven patients were included and received 50 mg/m(2) of doxorubicin and 75 mg/m(2) of docetaxel every two weeks for four cycles. Primary prophylaxis with granulocyte colony stimulating factor was administered. RESULTS Patients included had mainly stage III disease (66%). Efficacy and toxicity analyses were carried out on an intention-to-treat basis. After study treatment, the rate of clinical responses was 85% (95% CI: 75-95) with 6% judged as clinical complete responses. Surgery was performed on 94% patients for whom the breast was conserved in 27%. Only one patient obtained a pathological complete response (with no evidence of invasive or non-invasive tumour in the breast and the lymph nodes). In three additional patients, malignant cells were detected only in one lymph node. The single severe haematological toxicity was neutropenia, occurring in one patient (2%) and two cycles (1%), being grade 3 in one and grade 4 in the other. Severe non-haematological toxicities were grade 3, and the most common was asthenia (8% of patients), followed by cutaneous toxicity, arthromyalgia and stomatitis, which occurred in fewer than 4% of patients in each case. CONCLUSIONS The concomitant dose-dense administration of doxorubicin and docetaxel as neoadjuvant chemotherapy with granulocyte colony stimulating factor support is a feasible and effective schedule with a safe toxicity profile for women with large or locally advanced breast cancer.

Abstract
For accurate assessment of the response to primary chemotherapy (PCT) for locally advanced breast cancer, we measured reduction in total tumor volume (TTV) by using three-dimensional magnetic resonance imaging (3D MRI), and examined the relationship between this reduction and patient prognosis. Fifty-one patients with locally advanced breast cancer were treated with four cycles of docetaxel (60 mg/m(2)) before surgery. Tumor size was measured with calipers, ultrasonography (US) and conventional two-dimensional (2D) MRI before and after chemotherapy. TTV was measured with 3D MRI. These and other clinicopathological parameters were statistically analyzed to determine the prognosis for the patients. Median follow-up time was 46 months (1-64 months). Of the 51 patients, 25 developed distant recurrences. Patients whose TTV decreased by 75% or more after PCT showed significantly better prognosis than others, while tumor size measured with calipers, US and 2D MRI showed no significant relationship with patient prognosis. Of the clinicopathological parameters, only reduction in TTV and histological grade showed a significant association with distant recurrence-free survival (p = 0.03 and 0.02, log-rank test), while stepwise multivariate Cox's proportional hazards analysis identified TTV as the strongest independent prognostic factor. Reduction in TTV measured with 3D MRI can be a useful prognostic factor for patients with locally advanced breast cancer treated with PCT.

Abstract
The dosing schedule of docetaxel may affect its clinical activity and toxicity profile. Although triweekly docetaxel has higher antitumor activity but more severe hematological toxicity, weekly docetaxel seems to have less activity or fewer adverse events. To evaluate the efficacy and toxicity of biweekly docetaxel and mitoxantrone in patients with advanced breast cancer, the regimen consisting of docetaxel (60 mg/m), and mitoxantrone (8 mg/m) was administered intravenously to 59 patients every 2 weeks. Most (54.2%) of the patients experienced objective responses. The median time to progression for the whole group was 6.8 months. The median time to progression for patients with complete or partial response was 10.3 months, but only 3.6 months for patients with stable or progressive disease (P<0.001). Grade III/IV adverse events of neutropenia, thrombocytopenia, anemia, febrile neutropenia, and nausea/vomiting were documented in 61.0, 6.8, 3.4, 3.4, and 3.4% of the patients, respectively. The median overall survival was 16.9 months. In conclusion, biweekly use of docetaxel and mitoxantrone is a highly effective and well-tolerated regimen for patients with advanced breast cancer. The optimal dosage of docetaxel in combination with chemotherapeutic regimen may be given every 2 weeks.

Abstract
PURPOSE An anthracycline-based combination followed by, or combined with, a taxane is the sequence used in most adjuvant chemotherapy regimens. We hypothesized that administering the taxane before the anthracycline combination would be associated with fewer dose reductions and delays than the reverse sequence. To test this hypothesis, a randomized phase II multicenter adjuvant chemotherapy trial was performed. PATIENTS AND METHODS Fifty-six patients with axillary node-positive, nonmetastatic breast cancer were randomly assigned either to group A (docetaxel [DOC] 75 mg/m(2) intravenously [IV] every 14 days for four cycles followed by doxorubicin 60 mg/m(2) and cyclophosphamide 600 mg/m(2) [AC] IV every 14 days for four cycles); or to group B (AC followed by DOC) at the identical doses and schedule. Pegfilgrastim 6 mg subcutaneous injection was administered 1 day after the chemotherapy in all treatment cycles. The primary objective was to administer DOC without dose reductions or delays before or after AC and calculate the relative dose intensity (RDI) of DOC and AC. RESULTS The majority of toxicities were grade 0 to 2 irrespective of sequence. The RDI for DOC was 0.96 and 0.82, respectively, in groups A (DOC followed by AC) and B (AC followed by DOC), with more frequent dose reductions occurring in group B (46% v 18%). The RDI for AC was 0.95 and 0.98 in groups A and B, respectively. CONCLUSION The administration of DOC before AC results in fewer DOC dose reductions and a higher RDI than the reverse sequence. Larger trials evaluating the sequence of DOC before anthracyclines are justified.

Abstract
PURPOSE In order to evaluate the feasibility of dose-dense docetaxel followed by dose-dense AC (doxorubicin/cyclophosphamide) as adjuvant chemotherapy for operable breast cancer, we conducted a phase II study. PATIENTS AND METHODS In cohort 1, 28 patients received docetaxel 100 mg/m2 followed by doxorubicin 60 mg/m2 with cyclophosphamide 600 mg/m2, each every 2 weeks for 4 weeks (total of 8 cycles). Enrollment was discontinued because of stopping criteria based on significant toxicity (grade 4 hematologic toxicity or grade >or= 3 nonhematologic toxicity). In cohort 2, the docetaxel dose was reduced to 75 mg/m2; enrollment was discontinued after 18 patients. RESULTS Significant toxicity occurred in 79% and 72% of patients in cohorts 1 and 2, respectively, resulting in treatment delays in 50% and 17% of patients, respectively. The most common grade 4 hematologic toxicity was neutropenia, which occurred in 7% and 42% of cohort 1 patients during docetaxel and AC, respectively, and in none and 19% of cohort 2 patients, respectively. The most common grade >or= 3 nonhematologic toxicity was palmar-plantar erythrodysesthesia, which occurred in 25% and none of cohort 1 patients during docetaxel and AC, respectively. With docetaxel 75 mg/m2 and patient education encouraging routine use of topical strategies, grade 3 palmar-plantar erythrodysesthesia occurred in only 11% of cohort 2 patients. Grade 2 nail changes were also debilitating and occurred in 33% of cohort 1 patients during AC. CONCLUSION These phase II findings suggest that dose-dense docetaxel 100 mg/m2 followed by AC is not feasible and, until more studies are conducted, should be restricted to clinical studies.

Abstract
Myeloid colony-stimulating factors (granulocyte colony-stimulating factor [G-CSF] and granulocyte-macrophage colony-stimulating factor) are commonly used in clinical practice for the prevention of anticancer chemotherapy-induced neutropenia and its potentially life-threatening complications. Pegfilgrastim is a novel recombinant human G-CSF pharmaceutically developed by covalent binding of a polyethylene glycol molecule to the N-terminal sequence of filgrastim. Due to its unique neutrophil-mediated clearance, pegfilgrastim can be administered once per chemotherapy cycle. Clinical trials have demonstrated that a single, fixed, subcutaneous dose of pegfilgrastim is comparable in safety and efficacy to daily injections of filgrastim for decreasing the incidence of infection following myelosuppressive chemotherapy in patients with cancer. Recent trials have been conducted to evaluate the use of pegfilgrastim in different clinical settings, including support of dose-dense regimens, mobilization and transplantation of hematopoietic stem cells.
