Background: Emerging data highlight different clinical behaviors according to KRAS amino acid substitutions (AASs) in patients with non-small-cell lung cancer (NSCLC). We aimed to evaluate whether different KRAS AASs were associated with different responses to chemotherapy.
Patients And Methods: We retrospectively reviewed data from 1190 patients with KRAS mutations who underwent first-line platinum-based chemotherapy for stage IV NSCLC. The response to different chemotherapy regimens was evaluated using the Response Evaluation Criteria In Solid Tumors criteria (v 1.1). Overall survival and time to progression (TTP) were secondary endpoints.
Results: Taxane was associated with the best response in the entire cohort (odds ratio, 2.52; 95% confidence interval [CI], 1.82-3.48; P < .001), especially in G12V patients (odds ratio, 2.15; 95% CI, 1.05-4.41; P = .036). Taxane was associated with improved TTP in the entire cohort (hazard ratio [HR], 0.31; 95% CI, 0.26-0.38; P < .001), especially in G13D patients (HR, 0.47; 95% CI, 0.22-1.01; P = .054). Pemetrexed was associated with the worst TTP in the entire cohort, particularly in G12V patients, who had the worst response rates (HR, 0.55; 95% CI, 0.30-0.99; P = .049). No impact on overall survival was observed according to different chemotherapy regimens and AASs.
Conclusion: KRAS-specific AAS appears to induce different responses to chemotherapy regimens after first-line platinum-based chemotherapy in advanced NSCLC.

Background: Uterine clear cell carcinoma (UCCC) is a rare and aggressive subtype of endometrial cancer, often presenting at an advanced stage with poor prognosis. Treatment options for advanced or recurrent UCCC are currently limited, especially after platinum-based chemotherapy has failed.
Case Presentation: We present the case of a 49-year-old female diagnosed with stage IV uterine clear cell carcinoma.
Low-Dose Acyclovir Reduces the Reactivation of Herpes Simplex and Varicella Zoster Viruses After Allogeneic Stem Cell Transplantation.

Introduction: Reactivation of herpes simplex virus (HSV) and varicella zoster virus (VZV) is a potential complication following allogeneic stem cell transplantation (alloSCT). Since different doses and durations of acyclovir prophylaxis may be utilized across transplant centers, this study aimed to evaluate the effectiveness of a lower dose of acyclovir in preventing HSV and VZV reactivation in alloSCT recipients within our institution.
Methods: A retrospective chart review was conducted for patients who underwent alloSCT between April 2016 and May 2023.
Patients with non‑small cell lung cancer with the exon 21 L858R mutation: From distinct mechanisms to epidermal growth factor receptor tyrosine kinase inhibitor treatments (Review).

The most common oncogenic driver in non-small cell lung cancer (NSCLC) is epidermal growth factor receptor (EGFR) gene mutations, which are more common in Asian (30-50%) than in Caucasian (10-15%) populations. Exon 19 deletion (ex19del) and exon 21 L858R (ex21 L858R) mutations account for ~45 and 40% of all EGFR mutations, respectively. Moreover, EGFR-tyrosine kinase inhibitors (TKIs) may be more effective and improve the quality of life of patients with NSCLC more than chemotherapy regimens.

Background: Both the antibody-drug conjugate (ADC) enfortumab vedotin (EV) and programmed death-1 inhibitor pembrolizumab have been shown to provide survival benefits in patients previously treated with locally advanced or metastatic urothelial carcinoma (la/mUC). Cost-effectiveness is necessary to consider whether the increased efficacy of the two therapies will lead to higher prices for first-line treatment of previously untreated la/mUC.
Objectives: To guide the choice of EV plus pembrolizumab or chemotherapy for patients with previously untreated la/mUC.

Introduction: Cancer research has revolutionised the treatment, quality of life and life expectancy of people living with cancer. Systemic anti-cancer treatments have expanded to involve not only cytotoxic drugs, but targeted drugs and immunotherapy. Although highly effective in many patients, these drugs can cause serious and sometimes life-threatening adverse reactions.
