EGFR positive

Patients who underwent upfront surgery had a greater likelihood of being pN+; however, there was no difference in the likelihood of axillary lymph node dissection. Therefore, neoadjuvant systemic therapy use should be based on current systemic therapy guidelines and patient-centered shared multidisciplinary decision-making.

Similarly, while clinical factors and imaging tools may help identify early on patients at higher risk of experiencing TIC, no cardioprotective strategy has yet demonstrated robust and conclusive benefit. Despite the emergence of newer anti-HER2 agents and evolving treatment paradigms, trastuzumab will probably continue to serve as a key therapeutic backbone, especially for patients with lower risk HER2+ eBC.

She was initiated on palbociclib and letrozole treatment in April 2024...She was commenced on ribociclib and letrozole for relapsed metastatic liver disease in April 2023...Understanding the role of CDK4/6 inhibition and the link with psoriasis is important for optimizing therapeutic choices for patients with cancer with pre-existing or newly developed psoriasis. Given the increasing use of CDK4/6 inhibitors in cancer treatment, clinicians should be vigilant of the potential increased prevalence of psoriasis experienced in this patient cohort.

Patients were randomized 1:1 to receive zolbetuximab plus chemotherapy or placebo plus chemotherapy (mFOLFOX6 [modified folinic acid, 5-fluorouracil, and oxaliplatin] or CAPOX [capecitabine and oxaliplatin]). Zolbetuximab plus chemotherapy demonstrated favorable PFS and OS versus placebo plus chemotherapy in the Korean subgroup, with numerically greater efficacy compared with the overall pooled population. This may be potentially attributable to low rates of zolbetuximab discontinuation and toxicity management.

This study suggests that selected patients with de novo mBC and locoregional oligoprogression can benefit from breast surgery while maintaining the same systemic treatment, particularly in the setting of HER2-positive disease or a pre-oligoprogression PFS >1 year.

For ALK mutations, the analysis showed that patients with ALK-positive tumors had distinct radiological features, including a higher occurrence in the lower lobes and fewer ground glass nodules compared to the WT group. The study concluded that specific radiological and pathological characteristics, along with EGFR and ALK mutation statuses, could be used to guide the treatment and diagnosis of lung adenocarcinoma.

Patients with advanced NSCLC and refractory MPE have a poorer prognosis after first-line targeted therapy than those with non-refractory MPE. More aggressive systemic and local treatment approaches may offer better survival benefits in these patients.

Pyrotinib showed good antitumor activity in the treatment of patients with HER2-positive advanced breast cancer and displayed a degree of efficacy in patients with brain metastases. The main adverse reaction was diarrhea, which was mostly low to moderate in severity, and the incidence of high-grade AEs was generally low, with controllable toxicity.

Survival sequential analysis highlights subtype-specific surveillance priorities: intensified monitoring within 3 years for TNBC, focused follow-up at 7-8 years for HER2-positive subtype, and extended tracking for Luminal subtypes. Both nomograms and the RSF model demonstrated robust predictive performance, providing theoretical and practical tools for precision prognosis management in breast cancer.

The biological basis arises from the dual function of monocytes in promoting tumor-supportive environments and lymphocytes in facilitating immune monitoring. Through the capture of this immunological interaction, MLR acts as a low-risk and affordable method for risk assessment and treatment choices adapted to molecular subtype traits.

In patients with high-risk, residual invasive HER2-positive breast cancer, postneoadjuvant T-DXd resulted in a significantly higher likelihood of invasive disease-free survival than T-DM1; toxic effects were mainly gastrointestinal and hematologic. An important identified risk of T-DXd is interstitial lung disease, which requires appropriate monitoring and management.

Tucatinib addition to trastuzumab and pertuzumab demonstrated improvement in PFS with no new safety signals identified and may be an option for 1L maintenance therapy in patients with HER2+ MBC.
