Purpose: Medulloblastoma (MB) is rarely seen in adults. For adjuvant therapy in adults the same therapy protocols used in pediatric cases are used. The present study retrospectively evaluated the data of MB patients who were treated in different Oncology Centers in Turkey.
Methods: The data of 60 adult patients with MB from 8 Oncology Centers diagnosed between 2005 and 2012 were retrospectively analyzed.
Results: The median patient age was 28.8 years (range 16-54). The administered chemotherapy included procarbazine+lomustin+vincristine (group A, N=31) and cyclophosphamide/ifosfamide+vincristine+cisplatin (group B, N=13). Median chemotherapy courses were 4 (range 1-8). Median progression free survival (PFS) was 76 months and median overall survival (OS) has not been reached in both groups. In young female patients and in those who received adjuvant chemotherapy, median PFS and OS were longer but without statistical significance. Mean PFS and OS were 65.9 months and 101.2 months in group A and 113.6 months and 141.6 months in group B, respectively.
Conclusion: Improved survival results were obtained in women, in patients aged below 25 years, in those who underwent gross total excision (GTE) and in those who received adjuvant therapy with cyclophosphamide/ifosphamide.

Dysregulation of GABAergic inhibition is associated with pathological pain. Consequently, enhancement of GABAergic transmission represents a potential analgesic strategy. However, therapeutic potential of current GABA agonists and modulators is limited by unwanted side effects.

To assess whether metabolic syndrome can be used as a reference index to evaluate the efficacy of neoadjuvant chemotherapy treatment for breast cancer (BC). Seventy cases of female BC patients who received neoadjuvant chemotherapy treatment and surgical treatment at the Glandular Surgery Department of Hebei Provincial People's Hospital from January 2021 to December 2023 were retrospectively collected, and clinical data such as puncture pathology were recorded. The clinical data were analyzed by 1-way analysis using the χ2 test, and further multifactorial logistic regression analysis was performed for statistically significant differences.

Background: Chronic nonhealing neuropathic foot ulcers affect approximately 15% to 30% of patients with diabetes mellitus and are associated with significant morbidity and mortality. Although current strategies to address these chronic wounds include a multifactorial approach, clinical outcomes remain poor and warrant improvement. Platelet-rich plasma (PRP), derived from autologous or allogeneic blood, is an emerging regenerative product that aims to serve as an adjuvant to standard diabetic foot ulcer (DFU) treatment.
