BACKGROUND: Taxanes are effective chemotherapy drugs for breast cancer care, but adverse effects pose a significant challenge in cancer treatment. Taxane-induced fluid retention and lower-extremity edema are two of the important dose-limiting toxicity and result in decreased quality of life (QoL). However, there is no standard of care to alleviate the symptoms. We conducted a clinical study to assess the efficacy of short-term aroma lymphatic tressage therapy (ALTT) in reducing taxane-induced edema in breast cancer patients.
METHODS: In this phase 2 clinical trial, patients with edema of CTCAE grade 2 or higher were enrolled and conducted 8 sessions of ALTT. The primary endpoint was to determine the proportion of patients with a reduction in lower extremity circumference of 3% or more before and 6 weeks after starting ALTT. The change in QoL was assessed as the secondary endpoint using QoL questionnaires.
RESULTS: A total of 37 breast cancer patients completed the protocol and were analyzed. The median sum of the 3-point circumference (thigh, calf, and ankle) was 230.8 cm (IQR 218-243) in the baseline and 220.2 cm (IQR 212-236) at the end of the study. The average decrease of circumference was 3.8%. About, 23 patients (62%) experienced a circumference decrease of 3% or more. An improvement in every scale of FACT-TAXANE and EORTC-QLQ-C30 was observed when comparing questionnaire results before and at the end of the intervention (P < 0.0001).
CONCLUSIONS: Eight sessions of ALTT over 4 weeks were effective in reducing lower-extremity edema and resulted in improvement of QoL in patients with breast cancer.

UNASSIGNED: Cancer-related fatigue (CRF) occurs in nearly all patients with metastatic breast cancer (MBC).
UNASSIGNED: This real-world analysis aimed to describe the prevalence and importance of fatigue in patients with MBC within 3 months of treatment with single-agent taxane-based chemotherapy during the timeframe of 2020-2022 in the United States and Europe. It was also conducted to assess whether there was a difference in relapsed patients compared to patients diagnosed de novo.
UNASSIGNED: Electronic health records were analyzed from approximately 150 million patients to identify patients with MBC who underwent taxane treatment.
UNASSIGNED: In 2021, 50,490 patients had MBC, of whom 16,170 were diagnosed de novo and 34,330 experienced relapse. The proportion of patients undergoing taxane-based chemotherapy was 7.5% (n = 1220) and 13.4% (n = 4590), respectively, and the prevalence of any fatigue and CRF was similar between the groups (24.6% versus 25.7% and 6.6% versus 5.4%, respectively).
UNASSIGNED: At least one in four patients with MBC undergoing taxane-based treatment will experience fatigue. This highlights the importance of validating screening tools to identify CRF, which is necessary to advance clinical trials aimed at investigating treatment strategies to improve patient-centered outcomes for fatigue.

Triple-negative breast cancer (TNBC) represents a challenging malignancy with limited treatment options and a poor prognosis. Adjuvant therapies, including chemotherapy and immune checkpoint inhibitors (ICI), are commonly employed following breast conservation surgery. However, these treatments can lead to various adverse effects, including cutaneous complications and connective tissue disorders. Here, we present the case of a 54-year-old woman with TNBC who developed morphea, a form of localized scleroderma, following adjuvant chemotherapy and pembrolizumab administration. This case highlights the rarity of drug-induced morphea and emphasizes the importance of recognizing and managing such adverse events in breast cancer patients. We discuss the clinical characteristics, diagnostic challenges, and treatment considerations associated with drug-induced scleroderma-like lesions, as well as the potential mechanisms underlying their development. Furthermore, we review the literature on the incidence, clinical features, and outcomes of scleroderma-like lesions induced by chemotherapy and ICIs. This case underscores the need for increased awareness of immune-related adverse events in patients receiving immunotherapy, as well as the importance of individualized treatment approaches to optimize patient care and outcomes.

BACKGROUND: Microtubule polymerization is usually considered as the upstream of apoptotic cell death induced by taxanes, but recently published studies provide more insights into the mechanisms responsible for the antineoplastic effect of taxanes. In this study, we figure out the role of the stress-related PERK/eIF2α axis in tumor cell death upon taxane treatment along with paclitaxel resistance.
METHODS: Utilizing immunoblot assay, the activation status of PERK-eIF2α signaling was detected in a panel of cancer cell lines after the treatment of taxanes. The causal role of PERK-eIF2α signaling in the cancer cell apoptosis induced by taxanes was examined via pharmacological and genetic inhibitions of PERK. The relationship between microtubule polymerization and PERK-eIF2α activation was explored by immunofluorescent and immunoblotting assays. Eventaually, the combined therapeutic effect of paclitaxel (PTX) and CCT020312, a PERK agonist, was investigated in PTX-resistant breast cancer cells in vitro and in vivo.
RESULTS: PERK-eIF2α axis was dramatically activated by taxanes in several cancer cell types. Pharmacological or genetic inhibition of PERK efficiently impaired taxane-induced apoptotic cell death, independent of the cellular microtubule polymerization status. Moreover, PTX was able to activate the PERK/eIF2α axis in a very low concentration without triggering microtubule polymerization. In PTX-resistant breast cancer cells, the PERK/eIF2α axis was attenuated in comparison with the PTX-sensitive counterparts. Reactivation of the PERK/eIF2α axis in the PTX-resistant breast cancer cells with PERK agonist sensitized them to PTX in vitro. Combination treatment of the xenografted PTX-resistant breast tumors with PERK agonist and PTX validated the synergic effect of PTX and PERK activation in vivo.
CONCLUSIONS: Activation of the PERK/eIF2α axis is a pivotal prerequisite of taxanes to initiate cancer cell apoptosis, which is independent of the well-known microtubule polymerization-dependent manner. Simultaneous activation of PERK-eIF2α signaling would be a promising therapeutic strategy to overcome PTX resistance in breast cancer or other cancers.

OBJECTIVE: Treatment with taxanes can result in chemotherapy-induced peripheral neuropathy (CIPN). We investigated the efficacy and safety of mirogabalin for the treatment of CIPN in patients who had been administered perioperative chemotherapy including taxane-based agents for breast cancer.
METHODS: We retrospectively analyzed the case of 43 patients with early breast cancer who received a taxane as perioperative chemotherapy and were administered mirogabalin at the diagnosis of CIPN.
RESULTS: Thirty-six patients (83.7%) had grade 1 CIPN and the other seven patients (16.3%) had grade 2 CIPN. The median mirogabalin dose was 10 mg (5-30 mg). CIPN improved from grade 1 to 0 in 12 patients (27.9%) and from grade 2 to 1 in one patient (2.3%); 13 (30.2%) patients thus had an objective therapeutic response. There were no cases in which chemotherapy was reduced or discontinued due to CIPN. Adverse events were evaluated by Common Terminology Criteria for Adverse Events and included five cases of dizziness (11.7%), three of somnolence (7.0%), and two of nausea (4.7%), all of which were grade ≤2. There were no cases of serious (grade ≥3) adverse effects.
CONCLUSIONS: Mirogabalin may be effective and safe for treating CIPN of patients who receive a taxane in a perioperative breast cancer setting.

OBJECTIVE: To explore the experiences of utilising distal-extremity cryotherapy in reducing chemotherapy-induced peripheral neuropathy during Paclitaxel treatment on physical functioning, clinical and patient-reported outcomes, compared to standard care in people affected by breast cancer.
METHODS: Four databases and one register were searched on 11 April 2023 to identify all relevant studies meeting the inclusion and exclusion criteria. These were CINAHL (via EBSCOhost), Cochrane Central Register of Controlled Trials, Medline (via EBSCOhost), Scopus, and Web of Science Core Collection, with no limiters placed on any of the searches. Additionally, relevant systematic reviews were scrutinised for potentially relevant studies for screening.
RESULTS: Distal-extremity cryotherapy is a safe intervention with minimal risk for serious adverse events. However, insufficient data supports the mainstay clinical use of cryotherapy in reducing chemotherapy-induced peripheral neuropathy from Paclitaxel use within the breast cancer population. Heterogeneity in study design, cryotherapy mode, and measurement tools underscore the need for additional research.
CONCLUSIONS: Despite limited data on the impact of distal-extremity cryotherapy in preventing chemotherapy-induced peripheral neuropathy, there are valuable implications for nursing practice arising from this review.
CONCLUSIONS: Nurses play a vital role in the clinical and experiential journey of people with breast cancer, it is important that they understand the available evidence and act as patient advocates. Assisting patients in understanding current research and encouraging participation in future studies, thereby enhancing our knowledge, and strengthening the available evidence base.

BACKGROUND: Previous studies have shown that the addition of platinum to neoadjuvant chemotherapy (NAC) improved outcomes for patients with triple-negative breast cancer (TNBC). However, no studies have assessed the efficacy and safety of the combination of taxane and lobaplatin. In this study, we conducted a randomized controlled phase II clinical study to compare the efficacy and safety of taxane combined with lobaplatin or anthracycline.
METHODS: We randomly allocated patients with stage I-III TNBC into Arm A and Arm B. Arm A received six cycles of taxane combined with lobaplatin (TL). Arm B received six cycles of taxane combined with anthracycline and cyclophosphamide (TEC) or eight cycles of anthracycline combined with cyclophosphamide and sequential use of taxane (EC-T). Both Arms underwent surgery after NAC. The primary endpoint was the pathologic complete response (pCR). Secondary endpoints were event-free survival (EFS), overall survival (OS), and safety.
RESULTS: A total of 103 patients (51 in Arm A and 52 in Arm B) were assessed. The pCR rate of Arm A was significantly higher than that of Arm B (41.2% vs. 21.2%, P = 0.028). Patients with positive lymph nodes and low neutrophil-to-lymphocyte ratio (NLR) benefited significantly more from Arm A than those with negative lymph nodes and high NLR (Pinteraction = 0.001, Pinteraction = 0.012, respectively). There was no significant difference in EFS (P = 0.895) or OS (P = 0.633) between the two arms. The prevalence of grade-3/4 anemia was higher in Arm A (P = 0.015), and the prevalence of grade-3/4 neutropenia was higher in Arm B (P = 0.044).
CONCLUSIONS: Neoadjuvant taxane plus lobaplatin has shown better efficacy than taxane plus anthracycline, and both regimens have similar toxicity profiles. This trial may provide a reference for a better combination strategy of immunotherapy in NAC for TNBC in the future.

UNASSIGNED: This study aimed to assess the efficacy and safety of FOLFIRI and paclitaxel in patients with advanced gastric cancer (AGC) who were previously treated with first-line modified docetaxel, cisplatin, 5-fluorouracil (mDCF), or 5-fluorouracil, oxaliplatin, docetaxel (FLOT).
UNASSIGNED: Patients who received a triplet regimen in the first line setting and were treated with FOLFIRI or paclitaxel in the second-line treatment were included.
UNASSIGNED: The study included 198 patients, with 115 receiving FOLFIRI and 83 receiving paclitaxel. The median age was 58 (range = 24-69). The median progression-free survival (mPFS) was 5.2 [95% confidence interval (CI) = 4.4-5.5] months in the FOLFIRI arm, and 4.1 (95% CI = 3.3-4.6) months in the paclitaxel arm (p = .007). The median overall survival (mOS) was 9.4 (95% CI = 7.4-10.5) months in the FOLFIRI arm and 7.2 (95% CI = 5.6-8.3) months in the paclitaxel arm (p = .008). Grade 3-4 neuropathy was higher in patients receiving paclitaxel compared to those receiving FOLFIRI (p = .04). Grade 3-4 diarrhea was 8% in the FOLFIRI arm and 2.4% in the paclitaxel arm (p = .02).
UNASSIGNED: Beyond progression with docetaxel-based triplet chemotherapy, FOLFIRI may be preferred as a second-line treatment over paclitaxel due to its longer mPFS and mOS.

BACKGROUND: Studies have shown improvement in overall survival with anti-PD1/PD-L1 molecules in combination with cisplatin/carboplatin and etoposide as a first-line treatment for Small Cell Lung Cancer (SCLC). However, first-line efficacy remains limited and well below that observed in Non-Small Cell Lung Cancer (NSCLC). Etoposide may have a detrimental effect on lymphocyte activation, which could explain the limited benefit of immunotherapy in the first line and the lack of benefit in the second line for patients previously exposed to high levels of etoposide.
METHODS: We initiated a multicenter, single-arm, open-label phase II study of a chemotherapy regimen with durvalumab, combined with carboplatin and paclitaxel for extensive disease SCLC. Eligible patients will receive durvalumab plus carboplatin and paclitaxel every 3 weeks for up to 4 cycles, followed by durvalumab every 4 weeks until progression or unacceptable toxicity. A total of 67 patients will be enrolled in this study, with a 12-month enrollment period and 36-month follow-up. The primary endpoint is Overall Survival (OS) rate at 12 months. Secondary endpoints are best response rate, OS, OS at 24- and 36 months, progression free survival (PFS), duration of response, quality of life and safety.
RESULTS: This study aims to establish the efficacy of durvalumab combined with carboplatin and paclitaxel in patients with extensive disease Small Cell Lung Cancer.
