Comparison of neoadjuvant chemotherapy response and prognosis among pegylated liposomal doxorubicin, epirubicin and pirarubicin in HR ⩽ 10%/HER2-negative breast cancer: an exploratory real-world multicentre cohort study. (PubMed, Ther Adv Med Oncol)
For patients with pCR, the differences in EFS (log-rank p = 0.47) and OS (log-rank p = 0.38) were not statistically significant among the three groups, and the EFS (log-rank p = 0.59) and OS (log-rank p = 0.14) of non-pCR patients in the PLD group were similar to those in the epirubicin and pirarubicin groups. PLD had a similar therapeutic response and prognosis compared to epirubicin or pirarubicin in NAC for patients with HR ⩽ 10%/HER2 negative breast cancer, which means that PLD represents a potential NAC option.

Berberine increases the killing effect of pirarubicin on HCC cells by inhibiting ATG4B-autophagy pathway. (PubMed, Exp Cell Res)
Tumor-bearing experiments in nude mice showed that the combination treatment with BBR and THP significantly suppressed the growth of HCC xenografts. These results reveal that BBR is able to strengthen the killing effect of THP on HCC cells by repressing the ATG4B-autophagy pathway, which may provide novel insights into the improvement of chemotherapeutic efficacy of THP, and may be conducive to the further clinical application of THP in HCC treatment.

Food therapy of scutellarein ameliorates pirarubicin‑induced cardiotoxicity in rats by inhibiting apoptosis and ferroptosis through regulation of NOX2‑induced oxidative stress. (PubMed, Mol Med Rep)
However, cell treatment with the ferroptosis inhibitor, ferrostatin‑1, or inducer, erastin, could not significantly reduce or promote, respectively, the expression of NOX2. However, GSK significantly affected ferroptosis and GPX4 expression. Overall, the results of the present study indicated that food therapy with Sc ameliorated CTP via inhibition of apoptosis and ferroptosis through regulation of NOX2‑induced oxidative stress, thus suggesting that Sc may be a potential therapeutic drug against CTP.

DNA topoisomerase II inhibition potentiates osimertinib's therapeutic efficacy in EGFR-mutant non-small cell lung cancer models. (PubMed, J Clin Invest)
This study reported that the DNA topoisomerase II (Topo II) inhibitors, doxorubicin and etoposide (VP-16) synergistically decreased cell survival with enhanced induction of DNA damage and apoptosis in osimertinib-resistant cells, suppressed the growth of osimertinib-resistant tumors, and delayed the emergence of osimertinib acquired resistance. Enforced expression of an ectopic TOP2A gene in sensitive EGFRm NSCLC cells conferred resistance to osimertinib, whereas knockdown of TOP2A in osimertinib-resistant cell lines restored their response to undergo osimertinib-induced DNA damage and apoptosis. Together, these results reveal an essential role of Topo IIα inhibition in mediating the therapeutic efficacy of osimertinib against EGFRm NSCLC, providing scientific rationale for targeting Topo II to manage acquired resistance to osimertinib.

CircZCCHC2 decreases pirarubicin sensitivity and promotes triple-negative breast cancer development via the miR-1200/TPR axis. (PubMed, iScience)
It is demonstrated that circZCCHC2 plays a crucial role in the malignant progression of TNBC via the miR-1200/TPR axis, thereby activating the RAS-RAF-MEK-ERK pathway. The present results indicate that circZCCHC2 has the potential to serve as a novel prognostic biomarker for TNBC.

Validation of hyperthermia as an enhancer of chemotherapeutic efficacy: insights from a bladder cancer organoid model. (PubMed, Int J Hyperthermia)
The resulting organoids were treated with pirarubicin or gemcitabine at 37 °C or 42 °C. Finally, RNA sequencing revealed the IFN-γ signaling pathway to be associated with hyperthermia. Overall, hyperthermia combined with chemotherapy exerted better therapeutic effects than those of normothermic chemotherapy in grade 1-2 non-muscle-invasive bladder cancer, potentially through activation of the IFN-γ-JAK-STAT pathway.

Preliminary Results from a Phase 1/2 Study of Liposomal Annamycin (L-ANN) in Combination with Cytarabin for the Treatment of Patients with Acute Myeloid Leukemia (AML) That Is Refractory to or Relapsed (r/r) after Induction Therapy (ASH 2023)
The design of the novel liposomal L-annamycin (L-ANN) was the replacement of a basic amine at the C-3' position with a hydroxy group, which was shown to significantly reduce cardiotoxicity when compared with doxorubicin...All patients will also receive cytarabine 2... Initial data suggested that L-ANN is safe and active in heavily pretreated r/r AML patients with no signs of cardiotoxicity. This study is currently being conducted in Europe across 5 sites in Poland and 3 in Italy. Results from the Phase 2 portion of this study will be presented at the meeting.

Mechanisms of Secondary Leukemia Development Caused by Treatment with DNA Topoisomerase Inhibitors. (PubMed, Biochemistry (Mosc))
Recurrent chromosomal translocations in the therapy-related leukemia differ from chromosomal rearrangements associated with other neoplasias. Here, we reviewed the factors that drive chromosomal translocations induced by cancer treatment with DNA topoisomerase II inhibitors, such as mobility of ends of double-strand DNA breaks formed before the translocation and gain of function of fusion proteins generated as a result of translocation.

Analysis of risk factors for recurrence after transurethral resection of bladder tumor in patients with non-muscle invasive bladder cancer: 2-year follow-up outcomes. (PubMed, Oncology)
Our study highlights the importance of postoperative surveillance and individualized treatment for patients with NMIBC. Our findings show that high pathology grading, pirarubicin treatment, and BCG treatment are independent risk factors for recurrence after TURBT in patients with NMIBC. However, caution is warranted when interpreting our findings due to the small sample size and the need for further research to confirm the negative impact of Mitomycin and BCG on recurrence rates.

Anthracycline-induced cardiotoxicity - are we about to clear this hurdle? (PubMed, Eur J Cancer)
To prevent cardiotoxicity, several strategies are being followed: (i) angiotensin-converting enzyme inhibitors, sartans, beta-blockers, aldosterone antagonists, and statins; (ii) iron chelators; and (iii) by development of new anthracycline derivatives with little or no cardiotoxicity. This review will discuss clinically evaluated doxorubicin analogues that were developed as potentially non-cardiotoxic anticancer agents and include recent development of a novel liposomal anthracycline (L-Annamycin) for the treatment of soft-tissue sarcoma metastatic to the lung and acute myelogenous leukaemia.

Genome-Wide Screening Identifies Gene AKR1C1 Critical for Resistance to Pirarubicin in Bladder Cancer. (PubMed, Cancers (Basel))
Aspirin, which is an AKR1C1 inhibitor, could help reduce the drug resistance caused by AKR1C1. After receiving THP treatment, the bladder cancer cell lines could upregulate the expression of the AKR1C1 gene through the ROS/KEAP1/NRF2 pathway, leading to resistance to THP treatment. Using tempol, which is an inhibitor of ROS, could prevent the upregulation of AKR1C1 expression.

Dose escalation results from a first-in-human study of ABBV-400, a novel c-Met–targeting antibody-drug conjugate, in advanced solid tumors. (ASCO 2023)
The antibody-drug conjugate (ADC) ABBV-400 consists of the c-Met–targeting antibody telisotuzumab conjugated to a potent topoisomerase 1 inhibitor (Top1i) payload. On the basis of DLTs, a maximum tolerated dose of ABBV-400 was identified. At this dose, safety results appear comparable with other Top1i ADCs. Promising antitumor activity was seen with ABBV-400 across tumor types, justifying further evaluation in the ongoing dose expansion in NSCLC, GEA, and CRC.
