The results of in vivo animal experiments also showed that Tra-CM-MSN-PYR significantly inhibited tumor growth. These results indicate that Tra-CM-MSN-PYR has potential application as a targeted therapy for HER2-positive breast cancer in the future.

The pyrotinib-based therapy is effective for HER-2 positive breast cancer with BM, especially in 1st- or 2nd-line treatment, with tolerable adverse events. However, insufficient dosing of pyrotinib may impair efficacy outcomes.

Which implies that TTK is an oncogene in HER2 + BRCA and is a valuable research target.

Furthermore, the in vivo results demonstrated a pronounced anticancer effect of pyrotinib in the SKBR3 xenograft mouse model, concomitant with a reduction in HER2 expression. In summary, our findings provide novel insights into the mechanism of pyrotinib in the treatment of HER2+ BC.

The trial reached the pre-specified tpCR, had met the primary end point. Neoadjuvant pyrotinib, trastuzumab and nab-paclitaxel reached a high tpCR rate, with manageable toxicity, for patients with HER2-enriched subtype of HER2-positive breast cancer. Chemotherapy can be de-escalated in patients with HER2-enriched subtype breast cancer with BluePrint intrinsic subtyping.

The combination of pyrotinib with metronomic oral etoposide has achieved promising clinical benefits in heavily pretreated HER2-positive MBC, with acceptable and manageable toxicity.

Finally, phase II clinical trials involving HER2-altered NSCLC patients demonstrated promising treatment outcomes with trastuzumab deruxtecan, trastuzumab emtansine, pyrotinib, pyrotinib + apatinib and trastuzumab + pertuzumab + docetaxel. In conclusion, the prevalence of HER2 alteration among Malaysian NSCLC patients falls within the global range. A systematic review of clinical trials revealed promising treatment outcomes and Malaysian NSCLC patients with HER2 alterations are anticipated to similarly benefit from HER2-targeted therapies.

A population pharmacokinetic model of pyrotinib in HER2 positive breast cancer patients suggested that low serum total protein reduced the clearance rate of pyrotinib in patients. Clinical medical staff should pay attention to the liver function of patients with abnormal serum total protein and be alert to the occurrence of adverse drug reactions.

Our findings underscore the robust synergy between pyrotinib and trastuzumab in overcoming HER2 dependency and provide a rationale for pyrotinib, trastuzumab, and docetaxel as one of the optimal choices for patients with untreated HER2-positive metastatic breast cancer, who are dependent on the HER2 signalling cascade.

For metastatic HER2-positive breast cancer patients with abnormal PAM pathway activation and previous trastuzumab treatment, the combination of inetetamab with sirolimus and chemotherapy is equivalent to the combination of pyrotinib and chemotherapy. Therefore, this regimen could be a treatment option for PAM pathway-activated metastatic HER2-positive breast cancer patients.

Upon irradiation with near-infrared light, ICG generates high levels of intracellular reactive oxygen species and elevated temperature, enhancing chemotherapy effects of pyrotinib. This synergistic action boosts a highly effective anticancer effect promoting the ferroptosis pathway, providing an efficient therapeutic strategy for treating HER2-positive BC.

Due to its optimized antibody-dependent cell-mediated cytotoxicity effect compared with trastuzumab, it has shown good efficacy and safety in the treatment of HER2-positive advanced breast cancer (ABC)...Patients treated with inetetamab plus pyrotinib plus chemotherapy, especially with capecitabine, had the best outcomes (mPFS = 14.0 months)...Inetetamab-based combination therapy shows promising efficacy and good safety in patients with HER2-positive ABC. It is one of the late-line treatment options for Chinese patients with HER2-positive ABC.

After the standard first-line treatment including albumin-bound paclitaxel, trastuzumab and pertuzumab, and a second-line treatment involving pyrotinib, capecitabine, and radiotherapy did not produce the desired results, the patient was then administered anlotinib in combination with pyrotinib and letrozole as a third-line treatment, which led to a partial response (PR). The findings suggest that anti-angiogenic therapy, specifically anlotinib, could be regarded as a promising therapeutic option for BC patients with BM.

Master regulators of the causal networks included lenvatinib, pyrotinib, histone deacetylase 1 (HDAC1), mir-196, and erb-b2 receptor tyrosine kinase 2 (ERBB2). The analysis of the HDAC1-interacting network identified the involvement of EMT regulation via the growth factors pathway, the coronavirus pathogenesis pathway, and vorinostat. The network had RNA-RNA interactions with microRNAs such as mir-10, mir-15, mir-17, mir-19, mir-21, mir-223, mir-25, mir-27, mir-29, and mir-34. The molecular networks revealed in the study may lead to identifying drug targets for GC.

Despite resistance to multiple therapies, including trastuzumab and pertuzumab, the patient exhibited a remarkable therapeutic response to pyrotinib, tegafur combined with radiotherapy. This case provides evidence for the feasibility and potential efficacy of deploying pyrotinib in the salvage treatment of mCRC patients with HER2 amplification even though resistant to other anti-HER2 drugs.

For human epidermal growth factor receptor 2 (HER2)-positive breast cancer, a combination of trastuzumab and pertuzumab regimen were recommended as Level I recommendation for neoadjuvant and first line metastatic breast cancer. Pyrotinib is also recommended as Level I recommendation in first line and second line therapy according to the latest studies conducted in China...There was also a new chapter for HER2-low breast cancer stratified by HR status. We firmly believe that evidence-based, availability-concerned, and consensus-based guidelines will be more feasible for clinical practice in China and in other countries with similar situations.

The patient achieved partial remission and did not show any further progression during the follow-up period. For NSCLC patients with both EGFR mutation and HER2 amplification, the combination of almonertinib and pyrotinib is a valuable therapy that can continuously reduce tumor burden and achieve long-term survival.

Researchers have developed monoclonal antibodies like Trastuzumab and Pertuzumab against HER2 receptors, which have proven highly beneficial in cancer therapy. Bispecific antibodies like Zanidatamab and antibody-drug conjugates like T-DM1 have been developed to overcome the resistance associated with monotherapy. Small molecules such as Lapatinib, Neratinib, and Pyrotinib were initially developed for treating breast cancer...This comprehensive review covers the structural characteristics of HER2, the HER family signaling pathway mechanism, recent findings regarding HER2 receptor involvement in various cancers, and diverse HER2-targeted therapies. This information provides a comprehensive understanding of HER2-targeted strategies in the evolving field of cancer treatment.

The combination of pyrotinib and capecitabine has showed efficacy in these patients. There were no grade 4/5 AEs. Pyrotinib combined with metronomic vinorelbine showed promising efficacy and an acceptable safety profile in HER2-positive advanced breast cancer patients after trastuzumab failure.

This study exhibited the anti-OSCC effects of PYR in vitro and in vivo, and demonstrated PYR inhibited OSCC cells by inducing apoptosis via the HER2/ AKT and ERK pathway. The result of this study also indicated locally advanced OSCC patients might benefit from HER2 assay and EGFR/HER2 dual inhibit treatment.

Hence, the combination of Pyrotinib and Dual HER2 blockade treatment shows promise as a neoadjuvant therapy for locally advanced HER2-positive BC to achieve a pCR in surgery. Nevertheless, this conclusion necessitates additional validation via meticulously designed clinical research investigations encompassing larger patient populations.
