Abstract
Triple negative breast cancer (TNBC) is a subtype of breast cancer characterized by absence of estrogen (ER) receptor, progesterone (PR) receptor, and human epidermal growth factor-2 (HER-2) receptor. TNBC is an aggressive disease that develops early Chemoresistance. The major pitfall associated is its poor prognosis, low overall survival, high relapse, and mortality as compared to other types of breast cancer. Chemotherapy could be helpful but do not contribute to an increase in survival of patient. To overcome such obstacles, in our article we explored advanced therapy using genes and nanocarrier along with its conjugation to achieve high therapeutic profile with reduced side effect. siRNAs are one of the class of RNA associated with gene silencing. They also regulate the expression of certain proteins that are involved in development of tumor cells. But they are highly unstable. So, for efficient delivery of siRNA, very intelligent, efficient delivery systems are required. Several nanotechnologies based non-viral vectors such as liposome, micelles, nanoparticles, dendrimers, exosomes, nanorods and nanobubbles etc. offers enormous unique properties such as nanometric size range, targeting potential with the capability to link with several targeting moieties for the gene delivery. These non-viral vectors are much safer, effective and efficient system for the delivery of genes along with chemotherapeutics. This review provides an overview of TNBC, conventional and advanced treatment approach of TNBC along with understanding of current status of several nanocarriers used for the delivery of siRNA for the treatment of TNBC.

Development and Validation of a Nomogram for Individually Predicting Pathologic Complete Remission After Preoperative Chemotherapy in Chinese Breast Cancer: A Population-Based Study. Clin Breast Cancer 2020; 20:e682-e694. [PMID: 32713825 DOI: 10.1016/j.clbc.2020.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/14/2020] [Accepted: 06/26/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To explore the independent predictors of pathologic complete remission response (pCR) for Chinese patients with breast cancer (BC) after preoperative chemotherapy and to develop an individualized nomogram for predicting the probability of pCR. PATIENTS AND METHODS The clinicopathologic data of clinical stage I-III BC patients who received preoperative chemotherapy in Xijing Hospital were retrospectively analyzed. A total of 689 BC patients diagnosed in 2015-2017 were included in the training set to develop a nomogram. A separate cohort of 357 patients in the same center was regarded as a validation set for externally examining the performance of the model. The area under the receiver operating characteristic curve and calibration curve were used to verify the predictive performance of the nomogram. RESULTS Multivariate logistic regression analysis showed that independent predictors of pCR were menopause status at diagnosis, family history of BC, initial tumor size, estrogen receptor status, HER2/neu (human epidermal growth factor receptor 2) status, and Ki-67 expression. On the basis of these factors, a nomogram was developed using R software. Our nomogram had good discrimination in the training and validation set (area under the receiver operating characteristic curve, 0.762 and 0.768, respectively). The calibration curves further confirmed that the model performs well. CONCLUSION Menopause status and family history of BC were independent predictors of pCR after preoperative chemotherapy for the first time. The nomogram can accurately predict pCR rate in BC, which may provide some guidelines for breast surgery options and patient counseling.

Triple-Negative Breast Cancer: A Review of Conventional and Advanced Therapeutic Strategies. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17062078. [PMID: 32245065 PMCID: PMC7143295 DOI: 10.3390/ijerph17062078] [Citation(s) in RCA: 140] [Impact Index Per Article: 35.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 03/02/2020] [Accepted: 03/03/2020] [Indexed: 12/14/2022]
Abstract
Triple-negative breast cancer (TNBC) cells are deficient in estrogen, progesterone and ERBB2 receptor expression, presenting a particularly challenging therapeutic target due to their highly invasive nature and relatively low response to therapeutics. There is an absence of specific treatment strategies for this tumor subgroup, and hence TNBC is managed with conventional therapeutics, often leading to systemic relapse. In terms of histology and transcription profile these cancers have similarities to BRCA-1-linked breast cancers, and it is hypothesized that BRCA1 pathway is non-functional in this type of breast cancer. In this review article, we discuss the different receptors expressed by TNBC as well as the diversity of different signaling pathways targeted by TNBC therapeutics, for example, Notch, Hedgehog, Wnt/b-Catenin as well as TGF-beta signaling pathways. Additionally, many epidermal growth factor receptor (EGFR), poly (ADP-ribose) polymerase (PARP) and mammalian target of rapamycin (mTOR) inhibitors effectively inhibit the TNBCs, but they face challenges of either resistance to drugs or relapse. The resistance of TNBC to conventional therapeutic agents has helped in the advancement of advanced TNBC therapeutic approaches including hyperthermia, photodynamic therapy, as well as nanomedicine-based targeted therapeutics of drugs, miRNA, siRNA, and aptamers, which will also be discussed. Artificial intelligence is another tool that is presented to enhance the diagnosis of TNBC.

Abstract
Background Platinum salts have demonstrated sufficient efficacy and safety for consideration of their use in a neoadjuvant setting for triple negative breast cancer (TNBC). Patients and methods We retrospectively analyzed 145 TNBC cases to compare the activity and tolerability of cisplatin and carboplatin. Two groups received weekly paclitaxel and platinum salts. Results In total, 87% of patients in the cisplatin group and 82% of patients in the carboplatin group experienced a clinical objective response after four cycles (complete response or partial response; P=0.570). Pathological complete response (pCR) occurred similarly in the cisplatin group and the carboplatin group (44% versus 42%, P=0.789). In survival analysis, there was no difference between the two regimens. The most common grade 3/4 adverse events were neutropenia and leukopenia. Conclusion There was no significant difference between the groups in terms of adverse events. Both types of platinum salts and weekly paclitaxel are feasible therapies that achieved high pCR rates and tolerability in TNBC patients.

Abstract
BACKGROUND Although cis-diamminedichloro-platinum (CDDP) exhibits strong therapeutic effects in cancer chemotherapy, its adverse effects such as peripheral neuropathy, nephropathy, and vomiting are dose-limiting factors. Previous studies reported that chronotherapy decreased CDDP-induced nephropathy and vomiting. In the present study, we investigated the influence of dosing times on CDDP-induced peripheral neuropathy in rats. METHODS CDDP (4 mg/kg) was administered intravenously at 5:00 or 17:00 every 7 days for 4 weeks to male Sprague-Dawley rats, and saline was given to the control group. To assess the dosing time dependency of peripheral neuropathy, von-Frey test and hot-plate test were performed. RESULTS In order to estimate hypoalgesia, the hot-plate test was performed in rats administered CDDP weekly for 4 weeks. On day 28, the withdrawal latency to thermal stimulation was significantly prolonged in the 17:00-treated group than in the control and 5:00-treated groups. When the von-Frey test was performed to assess mechanical allodynia, the withdrawal threshold was significantly lower in the 5:00 and 17:00-treated groups than in the control group on day 6 after the first CDDP dose. The 5:00-treated group maintained allodynia throughout the experiment with the repeated administration of CDDP, whereas the 17:00-treated group deteriorated from allodynia to hypoalgesia. CONCLUSIONS It was revealed that the severe of CDDP-induced peripheral neuropathy was inhibited in the 5:00-treated group, whereas CDDP-treated groups exhibited mechanical allodynia. These results suggested that the selection of an optimal dosing time ameliorated CDDP-induced peripheral neuropathy.

Abstract
IMPORTANCE Different adjuvant chemotherapy regimens are available for early-stage breast cancer. Because conventional meta-analysis does not allow comparing all regimens, we performed a network meta-analysis to identify the most effective adjuvant chemotherapy regimen. OBJECTIVE To find the most effective adjuvant therapy regimen for early-stage breast cancer. DATA SOURCES We searched MEDLINE, Embase, and the Cochrane Library for articles published before June 2015; the American Society of Clinical Oncology annual meeting abstracts from January 1983 through December 2014; and the American Association for Cancer Research annual meeting abstracts from January 1916 through December 2014. Additionally, we manually searched bibliographies for related references. STUDY SELECTION We included randomized clinical trials of adjuvant treatments for early-stage breast cancer that compared 2 or more of the following: no adjuvant chemotherapy; sequential anthracycline-cyclophosphamide and taxane (AC-T); concurrent anthracycline-cyclophosphamide and taxane (ACT); anthracycline-cyclophosphamide without taxane (AC); docetaxel and cyclophosphamide (TC); cyclophosphamide, methotrexate, and fluorouracil (CMF); and platinum-containing regimens. DATA EXTRACTION AND SYNTHESIS We followed the PRISMA guidelines. Two investigators independently selected the articles and extracted information. Disagreements were resolved by discussion with another author. Quality was assessed by Cochrane risk-of-bias method. Data were pooled using random-effects models. MAIN OUTCOMES AND MEASURES We used network meta-analysis to test the most effective adjuvant therapy regimen in terms of overall survival (OS) by comparing regimens listed in the National Comprehensive Cancer Network guidelines and platinum-containing regimens. RESULTS We identified 24 trials. The TC and platinum-containing regimens had OS benefit similar to that of sequential AC-T (TC hazard ratio [HR], 0.93; 95% CI, 0.62-1.40; and platinum HR, 0.93; 95% CI, 0.66-1.31). Patients treated with CMF or AC had significantly worse OS than those treated with sequential AC-T (CMF HR, 1.56; 95% CI, 1.32-1.85; and AC HR, 1.22; 95% CI, 1.10-1.37). Platinum-containing regimens tended to be more toxic than sequential AC-T. The toxicity of TC was similar to or less than that of sequential AC-T. Meta-regression analysis showed that hormone receptor status did not impact the HRs for OS for any regimen. CONCLUSIONS AND RELEVANCE Sequential AC-T is likely to be the most effective adjuvant therapy regimen for early-stage breast cancer regardless of hormone receptor status.

A multicenter prospective phase II trial of neoadjuvant epirubicin, cyclophosphamide, and 5-fluorouracil (FEC100) followed by cisplatin-docetaxel with or without trastuzumab in locally advanced breast cancer. Cancer Chemother Pharmacol 2015; 77:147-53. [PMID: 26563257 DOI: 10.1007/s00280-015-2906-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2015] [Accepted: 11/04/2015] [Indexed: 10/22/2022]
Abstract
PURPOSE To evaluate the efficacy and safety profile of the (FEC100) followed by cisplatin/docetaxel with and without trastuzumab as primary chemotherapy for patients with locally advanced breast cancer (LABC). METHODS Eighty patients with LABC (T2-T4, N0-N2, M0) were enrolled to receive 24 weeks of neoadjuvant chemotherapy using epirubicin, cyclophosphamide, and 5-fluorouracil (FEC100) followed by cisplatin and docetaxel, plus trastuzumab if HER2 positive. The primary endpoint was pathologic complete response (pCR) in breast and axilla in separate HER2-negative and HER2-positive cohort. RESULTS Eighty patients were evaluable for analysis of which 51 were HER2 negative and 29 HER2 positive: median age: 43 years, premenopausal: 82%, median tumor size: 7.0 cm (4-10), stage IIB: 25% and IIIA/IIIB: 75%, both ER/PR positive: 56%, HER2 positive (3+) by IHC staining: 36%. Clinical complete response was seen in 48%, and clinical partial response was seen in 52%. Overall the pathologic complete response (pCR) was 36% in breast, 64 % in axilla, and 32% in both breast and axilla. Analysis of pCR in breast and axilla, as a function of the hormonal receptor (HR) and HER2, was as follows: HR(+)/HER2(-): 11%; HR(+)/HER(+): 56 %; HR(-)/HER2(-): 36%; HR(-)/HER2(+): 62%. CONCLUSION In this series of locally advanced breast cancer, the combination of (FEC100) followed by cisplatin/docetaxel with and without trastuzumab was very active obtaining an impressive rate of pCR, particularly in HER2-positive and triple negative disease, which merits further investigation.

Abstract
Triple-negative breast cancer (TNBC) is diagnosed more frequently in younger and premenopausal women and is highly prevalent in African American women. TNBC is a term derived from tumors that are characterized by the absence of ER, PgR, and HER2. So patients with TNBC do not benefit from hormonal or trastuzumab-based therapies. TNBCs are biologically aggressive, although some reports suggest that they respond to chemotherapy better than other types of breast cancer, prognosis remains poor. This is due to: shortened disease-free interval in the adjuvant and neoadjuvant setting and a more aggressive course in the metastatic setting.

Abstract
UNLABELLED Epigenetic modifiers, including the histone deacetylase inhibitor vorinostat, may sensitize tumors to chemotherapy and enhance outcomes. We conducted a multicenter randomized phase II neoadjuvant trial of carboplatin and nanoparticle albumin-bound paclitaxel (CP) with vorinostat or placebo in women with stage II/III, human epidermal growth factor receptor 2 (HER2)-negative breast cancer, in which we also examined whether change in maximum standardized uptake values corrected for lean body mass (SUL(max)) on (18)F-FDG PET predicted pathologic complete response (pCR) in breast and axillary lymph nodes. METHODS Participants were randomly assigned to 12 wk of preoperative carboplatin (area under the curve of 2, weekly) and nab-paclitaxel (100 mg/m(2) weekly) with vorinostat (400 mg orally daily, days 1-3 of every 7-d period) or placebo. All patients underwent (18)F-FDG PET and research biopsy at baseline and on cycle 1 day 15. The primary endpoint was the pCR rate. Secondary objectives included correlation of change in tumor SUL(max) on (18)F-FDG PET by cycle 1 day 15 with pCR and correlation of baseline and change in Ki-67 with pCR. RESULTS In an intent-to-treat analysis (n = 62), overall pCR was 27.4% (vorinostat, 25.8%; placebo, 29.0%). In a pooled analysis (n = 59), we observed a significant difference in median change in SUL(max) 15 d after initiating preoperative therapy between those achieving pCR versus not (percentage reduction, 63.0% vs. 32.9%; P = 0.003). Patients with 50% or greater reduction in SUL(max) were more likely to achieve pCR, which remained statistically significant in multivariable analysis including estrogen receptor status (odds ratio, 5.1; 95% confidence interval, 1.3-22.7; P = 0.023). Differences in baseline and change in Ki-67 were not significantly different between those achieving pCR versus not. CONCLUSION Preoperative CP with vorinostat or placebo is associated with similar pCR rates. Early change in SUL(max) on (18)F-FDG PET 15 d after the initiation of preoperative therapy has potential in predicting pCR in patients with HER2-negative breast cancer. Future studies will further test (18)F-FDG PET as a potential treatment-selection biomarker.

Abstract
BACKGROUND The aim of this study was to investigate the feasibility of sentinel lymph node biopsy (SLNB) after neoadjuant chemotherapy (NAC) in breast cancer patients with confirmed axillary nodal metastases. METHODS We enrolled 51 patients with breast cancer who received NAC. All patients were proven to have axillary nodal metastases by histopathology biopsy prior to NAC. They all underwent SLNB before breast surgery, and complete axillary lymph node dissection immediately followed. RESULTS The identification rate for SLNB was 87.5% (84/96); the false negative rate was 24.5% (12/49). The clinicopathological factors were not significantly correlated with the identification and false negative rate of the SLNB. Lymphatic mapping, blue dye or radionuclide methods tended to decrease the identification rate of SLNB (P = 0.073). Clinical nodal status before NAC has a trend to increase the false-negative rates of the SLNB (P = 0.059). For patients with N1 clinical axillary lymph nodal status, the identification rate was 93.9%, and the false negative rate was 5.9%, compared with N2-3 patients with 73.9% and 38.9%, respectively. CONCLUSIONS SLNB is feasible for the patients whose axillary lymph nodal status before NAC is N1. However, for N2-3 patients, SLNB cannot be used as an infallible indicator of non-SLN status.

Abstract
PURPOSE Preclinical data indicate that the combination of docetaxel, cisplatin and trastuzumab (TCH) may have the potential for clinically significant activity against breast cancers that overexpress the her2/neu gene (HER2). An open-label phase II trial was designed to investigate the response rate and toxicity profile of TCH in breast cancer patients with a primary tumor 2-5 cm in diameter (T2) in its original size. METHODS Thirty breast cancer patients with HER2-overexpressing tumors were enrolled. Patients received 6 cycles of docetaxel at 60 mg/m(2) and cisplatin at 50 mg/m(2) given on day 1 and then every 21 days. Trastuzumab was given on day 1, cycle 1 (4 mg/kg), and then continued weekly at 2 mg/kg for 1 year or until disease progression. Tumor measurements were obtained at baseline as well as after 3 and 6 cycles of chemotherapy. RESULTS We identified 29 breast cancer patients in Taiwan, of whom 13 (44.8%) had pathological complete responses. No cardiac toxicity was observed. Hematologic grade 4 or 3 toxicities were observed in 1 of 28 patients. Non-hematologic grade 4 or 3 toxicities with a reverse pattern were observed in 6 of 29 patients. CONCLUSIONS The results of our study indicate that TCH neoadjuvant chemotherapy is feasible and active in T2 HER2-overexpressing breast cancer patients in terms of pathological complete response rate, complete response, partial response and manageable toxicities.

Abstract
Neoadjuvant chemotherapy (NAC) has become a widely accepted method of sequencing systemic therapy for breast cancer treatment. While 'response to chemotherapy' in the neoadjuvant setting has been utilised to predict prognosis, the published data are inconsistent. The present meta-analysis was conducted to determine whether the pathologic response to NAC predicts for outcomes. Papers were selected from the PubMed database based on defined inclusion and exclusion criteria. Parameters such as number/percentage of patients having pCR and outcome statistics (i.e. overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS)) were collected. The analysis included 16 studies with 3776 patients. The summary odds ratio (OR) estimating the association of OS with pCR was 3.44 (95% confidence interval [95%CI]: 2.45-4.84), with similar findings for DFS (OR=3.41, 95%CI: 2.54-4.58) and RFS (OR=2.45, 95%CI: 1.59-3.80). No obvious statistical heterogeneity was detected. Funnel plots and Egger's tests did not reveal publication bias. This meta-analysis confirms that pathologic response is a prognostic indicator for RFS, DFS and OS and suggests that patients achieving pCR after NAC have favourable outcomes.

Abstract
We have previously demonstrated high pathologic response rates after neoadjuvant concurrent chemoradiation in patients with locally advanced breast cancer (LABC). We now report disease-free survival (DFS) and overall survival (OS) in the context of pathologic response. 105 LABC patients (White 46%, Non-White 54%) were treated with paclitaxel (30 mg/m² intravenously twice a week) for 10-12 weeks. Daily radiotherapy was delivered to breast, axillary, and supraclavicular lymph nodes during weeks 2-7 of paclitaxel treatment, at 1.8 Gy per fraction to a total dose of 45 Gy with a tumor boost of 14 Gy at 2 Gy/fraction. Pathological complete response (pCR) was defined as the absence of invasive cancer in breast and lymph nodes and pathological partial response (pPR) as the persistence of <10 microscopic foci of invasive carcinoma in breast or lymph nodes. Pathologic response (pCR and pPR) after neoadjuvant chemoradiation was achieved in 36/105 patients (34%) and was associated with significantly better DFS and OS. Pathological responders had a lower risk of recurrence or death (HR = 0.35, P = 0.01) and a longer OS (HR = 4.27, P = 0.01) compared with non-responders. Median DFS and OS were 57 and 84 months for non-responders, respectively, and have not yet been reached for responders. Importantly, pathologic response was achieved in 54% of patients with HR negative tumors (26/48). In conclusion, pathologic response to concurrent paclitaxel-radiation translated into superior DFS and OS. Half of the patients with HR negative tumors achieved a pathologic response.

Abstract
Cytotoxic chemotherapy remains the mainstay of treatment for triple-negative breast cancer (TNBC) despite the promise of new targeted and biologic agents. Many studies have shown significant benefit of chemotherapy in the neoadjuvant, adjuvant, and metastatic treatment of TNBC. Neoadjuvant chemotherapy studies have consistently reported higher response rates in TNBC than non-TNBC, and pathologic complete response has been shown to predict improved long-term outcomes for TNBC. Although the specific adjuvant regimens that may be most effective for TNBC are still being determined, third-generation chemotherapy regimens using dose dense or metronomic polychemotherapy are among the most effective tools presently available. The role of specific chemotherapy agents in the treatment of TNBC remains incompletely defined and warrants careful review to ensure that the most effective therapy is delivered while minimizing unnecessary toxicity. Platinum agents have seen renewed interest in TNBC based on a growing body of preclinical and clinical data suggesting encouraging activity. Taxanes and anthracyclines are active in TNBC and remain important agents but have not shown specific benefit over non-TNBC. Capecitabine has limited reported data in TNBC, but some reports suggest differential activity in TNBC compared with hormone receptor-positive breast cancer. TNBC is itself a heterogeneous group in which subgroups such as BRCA1 mutation carriers may have particular sensitivity to platinum agents and relatively less sensitivity to taxanes. Therefore, the identification of additional molecular biomarkers to predict response to specific chemotherapy is required to further improve treatment strategies with the current menu of chemotherapy options and future combinations with targeted therapies.

Abstract
BACKGROUND Findings from our previously published phase II study showed a high pathologic complete remission (pCR) rate in patients with triple-negative large operable breast cancer after the administration of eight cisplatin-epirubicin-paclitaxel (PET) weekly cycles. The safety and efficacy data of the initial population were updated, with inclusion of additional experience with the same therapy. METHODS Patients with triple-negative large operable breast cancer (T2-T3 N0-1; T > 3 cm) received eight preoperative weekly cycles of cisplatin 30 mg/m2, epirubicin 50 mg/m2, paclitaxel (Taxol) 120 mg/m2, with granulocyte colony-stimulating factor (5 microg/kg days 3-5) support. RESULTS Overall 74 consecutive patients (T2/T3 = 35/39; N0/N+ = 26/48) were treated, from May 1999 to May 2008. At pathological assessment, 46 women (62%; 95% confidence interval 50-73) showed pCR in both breast and axilla. At a 41-month median follow-up (range 3-119), 13 events (nine distant metastases) had occurred, 5-year projected disease-free survival (DFS) and distant disease-free survival being 76% and 84%, respectively. Five-year DFS was 90% and 56% in pCRs and non-pCRs, respectively. Severe neutropenia and anemia occurred in 23 (31%) and eight (10.8%) patients, respectively. Severe non-hematological toxicity was recorded in <20% of patients. Peripheral neuropathy was quite frequent but never severe. CONCLUSIONS Eight weekly PET cycles are a highly effective primary treatment in women with triple-negative large operable breast cancer. This approach results in a very promising long-term DFS in this poor prognosis population. This triplet regimen is worthy of evaluation in phase III trials.

Abstract
The present study aimed at evaluating whether a weekly cisplatin, epirubicin, and paclitaxel (PET) regimen could increase the pathological complete response (pCR) rate in comparison with a tri-weekly epirubicin and paclitaxel administration in locally advanced breast cancer (LABC) patients. Patients with stage IIIB disease were randomised to receive either 12 weekly cycles of cisplatin 30 mg m−2, epirubicin 50 mg m−2, and paclitaxel 120 mg m−2 (PET) plus granulocyte-colony stimulating factor support, or four cycles of epirubicin 90 mg m−2+paclitaxel 175 mg m−2 (ET) every 3 weeks. Overall, 200 patients (PET/ET=100/100) were included in this study. A pCR in both breast and axilla occurred in 16 (16%) PET patients and in six (6%) ET patients (P=0.02). The higher activity of PET was evident only in ER negative (27.5 vs 5.4%; P=0.026), and in HER/neu positive (31 vs 5%; P=0.037) tumours. The two arms yielded similar pCR rate in ER positive (PET/ET=7.5/7.1%) and HER/neu negative (PET/ET=10/6%) patients. At a 39 months median follow-up, 70 patients showed a progression or relapses (PET, 32 vs ET, 38). Anaemia, mucositis, peripheral neuropathy, and gastrointestinal toxicity were substantially more frequent in the PET arm. The PET weekly regimen is superior to ET in terms of pCR rate in LABC patients with ER negative and/or HER2 positive tumours Mature data in terms of disease-free and overall survival are needed to ascertain whether this approach could improve the prognosis of these subsets of LABC patients.

Abstract
BACKGROUND Emerging evidence suggests that induction of pathologic complete response (pCR) after primary systemic therapy (PST) is, at least to some extent, predictive of survival. However, standards for processing surgical specimens and for histopathologic evaluation of the pathologic response to therapy appear to be lacking. METHODS To perform a systematic review of representative articles on this topic, a computerized (MEDLINE) search was undertaken followed by a manual search based on the reference lists of the publications identified. RESULTS Several classification systems have been used to assess pathologic response to PST, the term pCR has not been applied in a consistent standardized manner, and only limited information is available about the reliability and validity of these classification systems. However, definitions of pCR can be summarized as follows: near pCR, only focal invasive tumor residues in the removed breast; quasi pCR, total or near total disappearance of invasive tumor in the removed breast; pCRinv, only in situ tumor residual in the removed breast; comprehensive pCR, no evidence of residual invasive tumor in the removed breast; strict pCR, disappearance of all tumor cells in the removed breast; comprehensive pCR (br+n), no evidence of residual invasive tumor in the breast and axillary nodes; strict pCR (br+n), no malignant tumor cells in the removed breast and axillary nodes. Comparison of the use of the term "pCR" in various trials reveals that it is not applied equivalently in these studies. CONCLUSION Assessment of pCR needs to be standardized, with verification for reliability and validity. For now, the non-equivalency in the definition of pCR should be taken into account when comparing the results of PST.

Abstract
PURPOSE The present study aimed to define the antitumor activity of eight cisplatin-epirubicin-paclitaxel (PET) weekly cycles with granulocyte colony-stimulating factor (G-CSF) support in patients with large operable breast cancer. METHODS Operable breast cancer (T2-3 N0-1; T >3 cm) patients received eight preoperative weekly cycles of cisplatin 30 mg/m2, epirubicin 50 mg/m2 and paclitaxel 120 mg/m2, with G-CSF (5 microg/kg, days 3-5) support. RESULTS Sixty-three patients (T2/T3=30/33; N0/N+=8/55) were enrolled. Thirty-one clinical complete (49%) and 30 partial (48%) responses were recorded, giving a 97% response rate (95% confidence interval 89% to 100%). Breast-sparing surgery was performed in 32/63 (51%) patients. At pathological assessment, 28 patients (45%) showed absence of invasive residual disease in breast and 34 (55%) had negative axilla. In 20 women (32%) both breast and axilla were found to be disease-free. At a 23-month median follow-up (range 4-63), only eight relapses and two deaths had occurred, with the 4-year projected relapse-free and overall survival being 59% and 95%, respectively. Grade 3-4 neutropenia and anemia occurred in 24% and 5% of patients, respectively. Emesis, diarrhea and mucositis were the main non-hematological toxicities; however, only nine (14%) patients experienced one or more episodes of severe non-hematological toxicity. Peripheral neuropathy was frequent, but never severe. CONCLUSIONS A 2-month weekly treatment with PET represents a well tolerated and highly effective approach in large operable breast cancer patients. In spite of the short duration of chemotherapy, one-third of patients achieved a complete eradication of the tumor in both breast and axilla.

Abstract
PURPOSE The management of unresectable locally advanced breast cancer (ULABC) remains a major challenge because of the necessity both to treat local disease and to prevent distant disease. Two consecutive Phase I/II trials of concomitant chemotherapy and radiation (CRT) were performed to attempt to address both local and distant disease control in ULABC. This analysis focuses on rates of locoregional control and radiation-associated acute and late complications. METHODS AND MATERIALS Thirty-three patients with unresectable locally advanced or inflammatory breast cancers (T4N0-3M0-1) or locally recurrent disease were treated with CRT on two consecutive Phase I/II trials. Radiotherapy consisted of 60-70 Gy to the breast or chest wall and 60 Gy to draining lymphatics in a week-on/week-off (WO/WO) schedule. Chemotherapy consisted of either continuous infusion or bolus paclitaxel +/- vinorelbine. A subset analysis of 16 patients with nonmetastatic ULABC Stage IIIB-C (T4N0-3M0) was performed. Among this cohort, 13 patients (81%) underwent planned mastectomy after CRT. RESULTS Of the 16 patients with Stage IIIB-C disease, acute toxicity included moist desquamation (n = 8) and Grade 3-4 neutropenia (n = 3). Late toxicity included breast reconstruction loss, decreased range of arm motion, lymphedema, and skin toxicity, although none was life-threatening. Of 15 assessable patients, 14 had a clinical response, 7 had a pathologic complete response (pCR) including 6 of 13 patients undergoing mastectomy. With a median follow-up for living patients of 43.8 months, the 4-year actuarial locoregional control, disease-free survival, and overall survival were 83%, 33%, and 56% respectively. CONCLUSIONS Concurrent WO/WO radiation therapy and paclitaxel +/- vinorelbine is effective locoregional therapy for ULABC with an acceptable toxicity profile. Further investigation of concurrent chemoradiotherapy in ULABC is warranted.
