The feasibility and anti-tumor activity of gemcitabine (GEM) as postoperative adjuvant chemotherapy were evaluated retrospectively. Between September 1998 and June 2007, patients with resected invasive pancreatic cancer (stage III, IVa, IVb) were given adjuvant chemotherapy with GEM (GEM group, n=10) or did not receive chemotherapy (n=11). Started the administration of GEM 38.5 days after surgery, and the mean duration was 15.4 months. Grade 3 or 4 adverse event was not observed in the GEM group. There was a significant difference in overall survival between the GEM group and the no-chemotherapy group (p=0.037), but there was no significant difference in disease-free survival between the two groups. Adjuvant chemotherapy with GEM was feasible and showed a benefit in patients with invasive pancreatic cancer.

Chemoresistance is a major obstacle in the treatment of gastric cancer (GC). Notably, aberrant expression of microRNAs (miRs) is closely related to tumor development and progression. In the present study, the role of miR-424-5p in the chemoresistance of GC was investigated.

Although osteosarcomas are the most frequent primary malignant bone tumors, the primary cranial manifestation of this condition is very rare with only a limited number of cases presented in the literature. We present the case of a 20-year-old male patient who underwent single-session surgical intervention for resection of right frontal osteosarcoma with a tailor-made craniotomy and cranioplasty using virtually designed 3D-printed templates and molds. Subsequently, the patient was treated according to the EURAMOS protocol and received adjuvant systemic chemotherapy.

Gliomas are tumours that affect the nervous system, with glioblastoma, also known as grade IV astrocytoma, being the most aggressive type, associated with poor prognosis. Glioblastoma is characterised by its highly invasive nature, rapid growth, and resistance to conventional chemotherapy and radiation treatments, resulting in a median survival of about 14 months. To improve patient outcomes, novel therapeutic approaches are needed.

Background: The PALLAS trial investigated the addition of palbociclib to standard adjuvant endocrine therapy to reduce breast cancer recurrence. This pre-specified analysis was conducted to determine whether adjuvant palbociclib benefited patients diagnosed with lower risk stage IIA disease compared to those with higher stage disease.
Methods: PALLAS was an international, multicenter, randomized, open-label, phase III trial, representing a public-private partnership between Pfizer, the Austrian Breast Cancer Study Group, and the U.
