Article Synopsis
  • Neoadjuvant chemotherapy (NAC) enhances survival rates in breast cancer patients by improving the rate of pathologic complete response (pCR), but research on blood-based indexes to predict pCR has produced mixed results.
  • A study of 304 patients used various blood indexes, including neutrophil-to-lymphocyte ratios (NLR), pan-immune inflammation values (PIV), and lactate dehydrogenase-albumin ratios (LAR), to assess their relationship with pCR and overall survival.
  • Results showed that PIV was the most significant predictor of pCR, while a high LAR was associated with increased recurrence risk and poor disease-free survival, revealing crucial insights for breast cancer treatment strategies.

Article Synopsis
  • This study aimed to evaluate the prognostic significance of the pan-immune-inflammation value (PIV) in patients with advanced pancreatic cancer, using a sample of 71 patients predominantly treated with the FOLFIRINOX regimen.
  • The results showed that high PIV values significantly correlated with increased mortality and poorer survival outcomes, with median overall survival being 9 months for high PIV patients compared to 26 months for those with lower values.
  • The findings suggest that PIV can serve as a valuable prognostic biomarker for patient outcomes in advanced pancreatic cancer and highlight the need for further research to confirm these results.

Article Synopsis
  • The study evaluated the effectiveness and safety of using granulocyte-colony stimulating factor (G-CSF) as a preventive treatment during chemoimmunotherapy for extensive-stage small cell lung cancer (ES-SCLC).
  • A total of 119 patients were analyzed, comparing those who received G-CSF to those who did not, with results indicating better response and disease control rates in the G-CSF group, although the differences were not statistically significant.
  • Overall, using G-CSF alongside the treatment protocol did not significantly improve efficacy or increase side effects, suggesting it can be safely integrated into treatment for ES-SCLC patients.

Introduction: Approximately 20-33% of all cancer patients are treated with acid-reducing agents (ARAs), most commonly proton pump inhibitors (PPIs), to reduce gastroesophageal reflux disease symptoms. Palbociclib and ribociclib are weak bases so their solubility depends on different pH. The solubility of palbociclib dramatically decreases to < 0.

Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality.
