Article Abstract

The scientific community has become more enthusiastic about ketogenic diet (KD) to improve the outcomes in medical conditions, including cancer by exploiting the reprogramed metabolism of cancer cells, making the diet a promising candidate as an adjuvant cancer therapy. From this perspective, the aim of this study was to provide a broad overview covering the therapeutic effects, evaluating the clinical evidence of clinical studies underlying the implementation of the KD in the context of cancer treatment and prognosis. A scoping literature search between the years 1990 and 2023 was carried out by using PRISMA guidelines and searching through different databases of the clinical studies supporting the effectiveness and benefits of KD in various carcinomas that could provide findings of evidence on the prognosis and clinical outcomes of cancer treatment. A total of 23 cancer-related publications were included, 12 of which focused on brain cancer particularly glioblastoma multiforme (GBM), 4 on both breast and ovarian cancers, and 3 on pancreatic cancer. A total of 10 publications were reported as clinical trials regarding cancers of the brain (4 studies), breast (2 studies), and ovarian (4 studies). Case report studies were reported in 3 publications for brain cancer, and 2 publications for breast cancer. Nearly almost of the studies found that there was a potential role of KD in the prognosis of cancer treatment. The current review suggests that cancer patients may get favorable effects from the implementation of KD to support clinical outcomes of cancer treatment.

Maladaptive role of peridroplet mitochondria during lipophagy disruption in pancreatic cancer.

Biochem Biophys Res Commun

Laboratory of Biopharmaceutics, Graduate School of Pharmaceutical Sciences, Chiba University, 1-8-1 Inohana, Chuo-ku, Chiba-city, Chiba, 260-8675, Japan. Electronic address:

Pancreatic ductal adenocarcinoma (PDAC) cells exhibit high metabolic flexibility, enabling survival under glucose limitation by using alternative fuels such as fatty acids. Lipophagy, a selective form of autophagy targeting lipid droplets (LDs), supports mitochondrial respiration during such nutrient stress. Our previous study demonstrated that the LSD1 inhibitor SP-2509 disrupts lipophagy independently of LSD1 inhibition, leading to LD accumulation and ATP depletion in glycolysis-suppressed PDAC cells.

The survival analysis of stage III and IV inoperable lung large cell neuroendocrine carcinoma and the role of LIPI in immunological stratification.

Lung Cancer

August 2025

Background: Large cell neuroendocrine carcinoma (LCNEC) represents a rare and unique type of lung tumor with an unfavorable prognosis. It is essential to summarize the treatment modalities and prognosis for inoperable stage III and IV LCNEC, explore the role of frontline immunotherapy, and examine the stratification role of the Lung Immune Prognostic Index (LIPI) and its relationship with the tumor microenvironment (TME).

Methods: This study retrospectively analyzed 160 patients with inoperable lung LCNEC (L-LCNEC) admitted to three hospitals from December 2012 to November 2023.

The purpose of the first three editions of the guidelines for external radiotherapy procedures (RecoRad™, published in 2008, 2016 and 2021 respectively), was to issue recommendations aimed at optimising, harmonising and standardising practices. The purpose of this fourth edition, follow the same plan and takes into account recent technological improvements along with findings from literature. Part one describes the daily use of general principles; part two describes every step of the process treatment for the main types of cancer.

Identifying meaningful drug response biomarkers from public pharmacogenomic datasets with biologically informed interpretable neural networks.

Comput Biol Chem

Faculty of Health Sciences, University of Macau, Avenida de Universidade, Taipa, Macao Special Administrative Region of China. Electronic address:

With the advancements of next-generation sequencing, publicly available pharmacogenomic datasets from cancer cell lines provide a handle for developing predictive models of drug responses and identifying associated biomarkers. However, many currently available predictive models are often just used as black boxes, lacking meaningful biological interpretations. In this study, we made use of open-source drug response data from cancer cell lines, in conjunction with KEGG pathway information, to develop sparse neural networks, K-net, enabling the prediction of drug response in EGFR signaling pathways and the identification of key biomarkers.
