Surgical resection represents the standard of care for people with newly diagnosed diffuse gliomas, and the neuropathological and molecular profile of the resected tissue guides clinical management and forms the basis for research. The Response Assessment in Neuro-Oncology (RANO) consortium is an international, multidisciplinary effort that aims to standardise research practice in neuro-oncology. These recommendations represent a multidisciplinary consensus from the four RANO groups: RANO resect, RANO recurrent glioblastoma, RANO radiotherapy, and RANO/PET for a standardised workflow to achieve a representative tumour evaluation in a disease characterised by intratumoural heterogeneity, including recommendations on which tumour regions should be surgically sampled, how to define those regions on the basis of preoperative imaging, and the optimal sample volume. Practical recommendations for tissue sampling are given for people with low-grade and high-grade gliomas, as well as for people with newly diagnosed and recurrent disease. Sampling of liquid biopsies is also addressed. A standardised workflow for subsequent handling of the resected tissue is proposed to avoid information loss due to decreasing tissue quality or insufficient clinical information. The recommendations offer a framework for prospective biobanking studies.

Prostate cancer (PCa) is the second leading cause of cancer-related mortality among men in the United States. While PCa initially responds to androgen deprivation therapy, a significant portion progresses to castration-resistant PCa. Approximately 20-25% of these cases acquire aggressive neuroendocrine (NE) features, ultimately leading to neuroendocrine prostate cancer (NEPC).

Despite these important advances, scRNA-seq is limited to measuring the transcriptome providing a partial view of cellular function. To address this limitation, multimodal scRNA-seq assays have emerged, allowing for the simultaneous measurement of RNA expression and protein.

The clinical implications of placental chromosomal mosaicism can be challenging for patients and health care providers. Key considerations include the specific characteristics of the chromosomal abnormality (such as size, gene content, and copy number), the timing of the mosaicism's onset during embryogenesis or fetal development, the types of tissues involved, and the level of mosaicism (the ratio of normal to abnormal cells within those tissues). Genetic counseling can help inform patients about the chances of having a live-born child with a chromosomal abnormality.

Background: To investigate the effect of nimotuzumab (N) combined with nab-paclitaxel, cisplatin, and fluorouracil (APF) neoadjuvant chemotherapy on the surgical margin.
Methods: 55 patients were divided into three groups: neoadjuvant chemotherapy and surgery group (G1, 15 cases), chemotherapy and surgery group (G2 group, 20 cases), and surgery group (G3 group, 20 cases). Tissue samples of the tumor core zone (P0), adjacent (P1, 3-5mm from tumor), distal adjacent (P2, 7-10mm from tumor), and surgical margin (P3, 15mm from tumor) were collected.
