Abstract
More than 10% of women diagnosed with breast cancer during reproductive age carry hereditary germline pathogenic variants in high-penetrance BRCA genes or in others genes involved in DNA repair mechanisms such as PALB2, BRIP or ATM. Anticancer treatments may have an additional negative impact on the ovarian reserve and subsequently on the fertility of young patients carrying such mutations. Recently, the combination of carboplatin and paclitaxel is being recommended to these BRCA-mutated patients as neoadjuvant therapy. However, the impact on the ovary is unknown. Here, we investigated their effect of on the ovarian reserve using mice carriers of BRCA1-interacting protein C-terminal helicase-1 (BRIP1) mutation that plays an important role in BRCA1-dependent DNA repair. Results revealed that the administration of carboplatin or paclitaxel did not affect the ovarian reserve although increased DNA double-strand breaks were observed with carboplatin alone. Co-administration of carboplatin and paclitaxel resulted in a significant reduction of the ovarian reserve leading to a lower IVF performance, and an activation of the PI3K-Pten pathway, irrespective of the genetic background. This study suggests that co-administration of carboplatin and paclitaxel induces cumulative ovarian damage and infertility but a heterozygote genetic predisposition for DNA damage related to BRCA1 gene function does not increase this risk.

The Affinity of Carboplatin to B-Vitamins and Nucleobases. Int J Mol Sci 2021; 22:ijms22073634. [PMID: 33807309 PMCID: PMC8037198 DOI: 10.3390/ijms22073634] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 03/26/2021] [Accepted: 03/28/2021] [Indexed: 11/17/2022] Open
Abstract
Platinum compounds have found wide application in the treatment of various types of cancer and carboplatin is one of the main platinum-based drugs used as antitumor agents. The anticancer activity of carboplatin arises from interacting with DNA and inducing programmed cell death. However, such interactions may occur with other chemical compounds, such as vitamins containing aromatic rings with lone-pair orbitals, which reduces the anti-cancer effect of carboplatin. The most important aspect of the conducted research was related to the evaluation of carboplatin affinity to vitamins from the B group and the potential impact of such interactions on the reduction of therapeutic capabilities of carboplatin in anticancer therapy. Realized computations, including estimation of Gibbs Free Energies, allowed for the identification of the most reactive molecule, namely vitamin B6 (pyridoxal phosphate). In this case, the computational estimations indicating carboplatin reactivity were confirmed by spectrophotometric measurements.

Disulfiram potentiates docetaxel cytotoxicity in breast cancer cells through enhanced ROS and autophagy. Pharmacol Rep 2020; 72:1749-1765. [PMID: 32617902 DOI: 10.1007/s43440-020-00122-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 06/03/2020] [Accepted: 06/23/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Recent studies have demonstrated that autophagy plays a critical role in reducing the drug sensitivity of docetaxel (DTX) therapy. Disulfiram (DSF) has exhibited potent autophagy inducing activity in multiple studies. We hypothesized that DSF co-treatment could sensitize breast cancer cells to DTX therapy via autophagy modulation. METHODS Breast cancer cells, MCF7, and 4T1, were treated with DTX and DSF, alone and in combination. The effects were analyzed by evaluating cytotoxicity, induction of apoptosis, induction of autophagy, and reactive oxygen species (ROS) generation. In addition, the consequence of autophagy and ROS inhibition on the DTX + DSF mediated cytotoxicity was also evaluated. RESULTS Significant synergism in cytotoxicity was observed with DTX + DSF combination in breast cancer cells, MCF7, and 4T1. Hyper induction of ROS and autophagy was also found with the combination treatment. ROS inhibition by N-Acetyl Cysteine (NAC), as well as autophagy inhibition by ATG5 silencing significantly reduced the autophagy level as well as cytotoxicity of the DTX + DSF combination, indicating that the induction of autophagy mediated by high ROS generation played a critical role behind the synergistic cytotoxicity. CONCLUSIONS This study indicates that DTX + DSF combination therapy can effectively sensitize cancer cells by hyper inducing autophagy through ROS generation and can be developed as a therapeutic strategy for cancer treatment in the future.

Abstract
PURPOSE The purpose of this study was to evaluate the efficacy and safety of nanosomal docetaxel lipid suspension (NDLS, DoceAqualip)-based chemotherapy in breast cancer. METHODS Medical charts of patients with breast cancer, who were treated and followed up with NDLS (75-100 mg/m2; 3-week cycle)-based chemotherapy from August 2014 to September 2018, were analyzed in this multicenter, retrospective study. The study endpoints were overall response rate (ORR: complete response [CR]+partial response [PR]) and disease control rate (DCR: CR+PR+stable disease [SD]) in neoadjuvant and metastatic settings. Overall survival (OS) and safety were evaluated for all settings. RESULTS Of 91 patients (neoadjuvant: 12, adjuvant: 61, metastatic: 18), efficacy evaluation in 29 patients (neoadjuvant: 12/12, metastatic: 17/18) demonstrated an ORR and DCR of 100%, respectively, in the neoadjuvant setting, and an ORR of 64.7% and DCR of 70.6%, respectively, in the metastatic setting. At a median follow-up of 21.6 months (range: 2.1 to 49.9 months), median OS was not reached in neoadjuvant and adjuvant settings, and it was 30.4 months in metastatic settings. At least one adverse event (AE) was reported in 59.3% of patients. Anemia, thrombocytopenia, lymphopenia, and neutropenia were the most common hematological AEs reported while hyperglycemia and alteration in liver function tests were the most common non-hematological AEs. NDLS-based treatment was well tolerated without any new safety concerns. CONCLUSION Nanosomal docetaxel lipid suspension-based chemotherapy was efficacious and well tolerated in the treatment of breast cancer. Further, NDLS is being evaluated prospectively in patients with triple-negative breast cancer (ClinicalTrials.gov: NCT03671044).

Outcome for triple negative breast cancer in a retrospective cohort with an emphasis on response to platinum-based neoadjuvant therapy. Breast Cancer Res Treat 2018; 174:1-13. [PMID: 30488345 PMCID: PMC6418073 DOI: 10.1007/s10549-018-5066-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Accepted: 11/19/2018] [Indexed: 12/18/2022]
Abstract
Purpose The rate of pathological complete response (pCR) for patients with triple negative breast cancer (TNBC) is increased when carboplatin is added to neo-adjuvant chemotherapy (NACT). However, while phase III trial data showing a survival benefit are awaited, carboplatin is not yet standard-of-care for TNBC. The aim of this study was to examine the rate of pCR and the outcome for those treated with carboplatin and to examine the predictors of response to therapy. Methods The retrospective series comprised 333 consecutive patients with TNBC (median follow-up time, 43 months). Adjuvant chemotherapy was given to 51% (n = 168) of patients and 29% (n = 97) received anthracycline–taxane NACT with carboplatin given to 9% (n = 31) of patients. Results Overall, 25% (n = 78) of patients experienced a breast cancer recurrence and 22% (n = 68) died from disease. A pCR breast and pCR breast/axilla was more common in those who received carboplatin (n = 18, 58% and n = 17, 55%, respectively) compared those who did not (n = 23, 36% and n = 18, 28%, respectively) (p = 0.041 and p = 0.011, respectively). By multivariable analysis, carboplatin and high tumor grade were independent predictors of pCR breast/axilla (ORnon-pCR = 0.17; 95% CI 0.06–0.54; p = 0.002; and ORnon-pCR = 0.05, 95% CI 0.01–0.27; p < 0.001, respectively). pCR breast/axilla was an independent predictor of DFS (HRnon-pCR=6.23; 95% CI 1.36–28.50; p = 0.018), metastasis-free survival (HRnon-pCR = 5.08; 95% CI 1.09–23.65; p = 0.038) and BCSS (HRnon-pCR = 8.52; 95% CI 1.09–66.64; p = 0.041). Conclusion Carboplatin therapy and high tumor grade are associated with a significant increase in the rate of pCR, which is an independent predictor of outcome. These data support the use of carboplatin in NACT for TNBC, while results from phase III studies are awaited.

Abstract
Triple negative breast cancers (TNBCs), which are defined as estrogen-receptor, progesterone-receptor, and HER2-receptor negative, account for 10-20% of breast cancers, and they are associated with early metastasis, chemotherapeutic resistance, and poor survival rates. One aspect of TNBC that complicates its prognosis and the development of new molecular therapeutic targets is its clinical and molecular heterogeneity. Herein we compare TNBC and basal cytokeratin-positive breast cancers. We examine the different TNBC molecular subtypes, based on gene expression profiling, which include basal-like, mesenchymal, and luminal androgen receptors, in the context of their biology and impact on TNBC prognosis. We explore the potential role of inducible nitric oxide synthase (iNOS) in TNBC tumor biology and treatment responses. iNOS has been shown to induce p53 mutation accumulation, basal-like gene signature enrichment, and transactivation of the epidermal growth factor receptor (EGFR) via S-nitrosylation, all of which are key components of TNBC biology. Moreover, iNOS predicts poor outcome in TNBC, and iNOS inhibitors show efficacy against TNBC when used in combination with chemotherapy. We discuss molecular targeted approaches, including EGFR, PARP, and VEGF inhibitors and immunotherapeutics, that are under consideration for the treatment of TNBC and what role, if any, iNOS may play in their success.

Abstract
Carboplatin is a derivative of cisplatin; it has a similar mechanism of action, but differs in terms of structure and toxicity. It was approved by the FDA in the 1980s and since then it has been widely used in the treatment of several tumor types. This agent is characterized by its ability to generate lesions in DNA through the formation of adducts with platinum, thereby inhibiting replication and transcription and leading to cell death. However, its use can lead to serious inconvenience arising from the development of resistance that some patients acquire during treatment, limiting the scope of its full potential. Currently, the biochemical mechanisms related to resistance are not precisely known. Therefore, knowledge of pathways associated with resistance caused by carboplatin exposure may provide valuable clues for more efficient rational drug design in platinum-based therapy and the development of new therapeutic strategies. In this narrative review, we discuss some of the known mechanisms of resistance to platinum-based drugs, especially carboplatin.

Abstract
SUMMARY Aim: To determine the incidence of febrile neutropenia (FN) following adjuvant chemotherapy with docetaxel, carboplatin and trastuzumab (TCH) for early-stage breast cancer and the grade of neutropenia after cycle one. Methods: A retrospective multicenter audit of patients with early-stage breast cancer treated with TCH, was conducted at four Australian hospitals between October 2009 and September 2013. Results: Of 79 patients analyzed, data from 78 women were evaluated for FN incidence and data from 64 women were evaluated for grade of neutropenia. After cycle one of TCH, 26 patients developed FN (33.3%). Following all cycles, 32 patients developed FN (41.0%). There was no statistical difference in the incidence of FN between hospitals or between age groups (above or below 65 years). After cycle one, ten patients developed grade 3 neutropenia (15.6%) and 37 patients developed grade 4 neutropenia (57.8%). Conclusion: This study demonstrates a high incidence of FN post-TCH chemotherapy thus supporting the use of granulocyte colony-stimulating factor as primary prophylaxis.

Abstract
OBJECTIVE We conducted a multicenter phase II trial to assess the efficacy and toxicity of docetaxel and carboplatin combination as neoadjuvant therapy for stage II or III breast cancer (BC). METHODS Patients received 75 mg/m of docetaxel and AUC 6 of carboplatin on day 1 followed by pegfilgrastim on day 2, every 14 days for 4 cycles, followed by definitive breast surgery. The primary endpoint was the proportion of patients achieving pathologic complete remission (pCR), defined as disappearance of all invasive and in situ tumors in the breast and axilla after chemotherapy. RESULTS A total of 57 women (median age, 53 y) were enrolled. Thirty-eight (67%) had ER+, 31 (54%) PR+, and 6 (11%) HER2+ disease; 9 had triple negative BC (TNBC). Forty-three (75%; 95% confidence interval, 62%-86%) of 57 eligible patients had clinical response (15 clinical complete response, 28 clinical partial response). Nine (16%; 90% confidence interval, 10%-28%) patients achieved pCR. Four of 9 (44%) patients with TNBC achieved pCR. Thrombocytopenia (5%) was the only grade 4 adverse event. The most common grade 3 adverse events were thrombocytopenia (19%), fatigue (12%), and anemia (9%). CONCLUSIONS Four cycles of 2-weekly Docetaxel and Carboplatin are feasible with acceptable toxicity and a pCR rate of 16%. This regimen can be considered for neoadjuvant therapy of BC, particularly for patients not eligible for anthracycline therapy. A high pCR rate of 44% noted in a subset of patients with TNBC is encouraging and needs to be validated in large prospective trials.

Abstract
BACKGROUND Triple negative metastatic breast cancer can be difficult to treat with primarily cytotoxic options. Nab-paclitaxel has demonstrated improved PFS and tolerability compared with standard cremophor-solubilized paclitaxel; based on this, we examined the efficacy and safety of combining weekly nab-paclitaxel with carboplatin and bevacizumab in TNMBC. PATIENTS AND METHODS In this phase II, multicenter trial, patients with first-line TNMBC received nab-paclitaxel (100 mg/m(2)) and carboplatin (area under the curve = 2) on days 1, 8, 15, and bevacizumab (10 mg/kg) on days 1 and 15 of a 28-day cycle. The primary end point was safety and tolerability and secondary end points included PFS, ORR, and CBR. PFS was calculated using the Kaplan-Meier method. RESULTS Between July 16, 2007, and October 3, 2011, 34 patients were enrolled at 4 centers. Median age was 50.0 (range, 30-76) years and 77% (n = 26) of patients received previous adjuvant therapy. Median PFS was 9.2 months (95% confidence interval [CI], 7.8-25.1 months). The CBR was 94% (95% CI, 80%-99%), and ORR was 85% (95% CI, 69%-95%) for the combination. The regimen was well tolerated with the most common grade 3/4 adverse events being neutropenia (n = 18; 53%) and thrombocytopenia (n = 6; 18%), with other serous events including 1 grade 3 and 1 grade 4 thrombotic event and 1 febrile neutropenia. CONCLUSION The combination of nab-paclitaxel, bevacizumab, and carboplatin as first-line treatment for TNMBC was efficacious and well tolerated. The PFS, CBR, and ORR, and tolerability of the regimen, compares favorably with other standard first-line therapies.

Abstract
Preclinical data have shown the potential of the intraductal administration of chemotherapy for breast cancer prevention. Direct translation of this work has been stymied by the anatomical differences between rodents (one duct per teat) and women (5-9 ductal systems per breast). The objective of this phase I study was to show the safety and feasibility of intraductal administration of chemotherapy drugs into multiple ducts within one breast in women awaiting mastectomy for treatment of invasive cancer. Thirty subjects were enrolled in this dose escalation study conducted at a single center in Beijing, China. Under local anesthetic, one of two chemotherapy drugs, carboplatin or pegylated liposomal doxorubicin (PLD), was administered into five to eight ducts at three dose levels. Pharmacokinetic analysis has shown that carboplatin was rapidly absorbed into the bloodstream, whereas PLD, though more erratic, was absorbed after a delay. Pathologic analysis showed marked effects on breast duct epithelium in ducts treated with either drug compared with untreated ducts. The study investigators had no difficulty in identifying or cannulating ducts except in one case with a central cancer with subareolar involvement. This study shows the safety and feasibility of intraductal administration of chemotherapy into multiple ducts for the purpose of breast cancer prevention. This is an important step toward implementation of this strategy as a "chemical mastectomy", where the potential for carcinogenesis in the ductal epithelium is eliminated pharmacologically, locally, and without the need for surgery.

Abstract
The role of platinum-based compounds (PBCs) in the treatment of metastatic breast cancer (MBC) has been extensively studied. As single agents, high response rates have been observed in first-line therapy, while results in pretreated patients were discouraging. Regimens containing cisplatin/carboplatin together with taxanes showed the highest efficacy and safety as both first-line and second-line therapy. When administered with vinorelbine, the combination was also active and well tolerated in anthracycline- and taxane-pretreated patients. Combining PBCs with etoposide or nucleoside analogues showed moderate activity, yet high toxicity in the case of etoposide. The overall results for the combination with anthracyclines were disappointing. Addition of trastuzumab to PBC combinations showed remarkable activity and good tolerability in patients with HER2/neu overexpression. The use of cisplatin or carboplatin alongside novel targeted therapeutics for patients with triple-negative MBC seems promising and is being further evaluated. The use of PBCs against MBC requires careful patient selection and combination with the right chemotherapeutic agent.

Abstract
The combination of docetaxel and cisplatin has shown promising results in anthracycline-pretreated patients with advanced breast cancer, but with substantial toxicity. The efficacy and safety in anthracycline-naive patients has not been evaluated. Between October 2003 and January 2006, we enrolled 39 patients. None had undergone chemotherapy for metastatic disease or been exposure to adjuvant anthracycline-based regimens earlier. Eligibility criteria included: histologically proven metastatic cancer; WHO performance status (PS) 0-2; and adequate hematological, hepatic and renal function. Docetaxel (70 mg/m) and cisplatin (50 mg/m) were administered every 3 weeks until the patient either refused to continue, or progression, or even unacceptable toxicity occurred. Tumor response was assessed every three cycles. One patient was withdrawn from response analysis because of toxicity. Thirty-eight patients had a complete tumor assessment. Median age was 50 years (range, 28-63); 5.1% had a WHO of PS of 0; 87% a PS of 1; 7.7% a PS of 2; in 69%, two or more organs were involved. A total of 291 cycles (range, 1-9) were administered. Three complete responses and 27 partial responses (intent-to-treat response rate 30/39=76.9%) resulted; disease remained stable in six patients and two had disease progression. Grade III/IV toxicities included diarrhea in 10.2%, asthenia/fatigue in 2.5%, mucositis in 5.1% and neutropenia in 87.3% of patients. Seven patients developed febrile neutropenia (17.9%). The median time to progression was 11.2 months; the timespan was not sufficient to track the median survival. Docetaxel/cisplatin is an active regimen with acceptable toxicity in the first-line treatment of metastatic breast cancer, but it is not sufficiently promising as a standard. Further randomized study is warranted.

A Clinical Phase II Study of a Non-Anthracycline Sequential Combination of Cisplatin-Vinorelbine Followed by Docetaxel as First-Line Treatment in Metastatic Breast Cancer. Oncology 2007; 70:330-8. [PMID: 17164589 DOI: 10.1159/000097945] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2006] [Accepted: 07/07/2006] [Indexed: 11/19/2022]
Abstract
BACKGROUND We tested a sequential combination regimen using cisplatin and vinorelbine (PVn) followed by docetaxel as first-line chemotherapy in a phase II clinical trial in metastatic breast cancer (MBC). PATIENTS AND METHODS Thirty-five patients were enrolled. Cisplatin 80 mg/m(2) was given on day 1 and vinorelbine 30 mg/m(2) on days 1 and 8 every 3 weeks for 4 cycles. Responding patients received docetaxel 75 mg/m(2) every 21 days for a maximum of 4 cycles. Three patients were excluded from analysis because of death unrelated to treatment. RESULTS After a median follow-up of 14 months, 32 patients completed the study. The overall response rate was 53.1%. Complete remission was seen in 5 patients (15.6%), partial response in 12 (37.5%), stable disease in 6 (18.75%), and progressive disease in 9 patients (28.1%). Median time to disease progression was 8 months (range 1-24). At 24 months, 12 (37.5%) patients were alive. A total of 183 cycles were administered. Febrile neutropenia was observed in 4 patients (2.2%). Grade II nephrotoxicity occurred in 12 cycles (6.5%) and grade III vomiting in 31/183 cycles (16.9%). DISCUSSION PVn is a feasible non-anthracycline option as first-line chemotherapy in patients with metastatic breast cancer and has acceptable toxicity. The sequential addition of 4 cycles of docetaxel following 4 cycles of PVn did not improve the overall response rate and results.
