Potential target in treatment of oral cancer discovered

(Boston University Medical Center) For the first time, researchers have identified a reliable marker (PDGFRβ) to detect carcinoma-associated fibroblasts (cells within the tumor that encourage growth and metastasis) (CAFs) in oral cancer tissues. With this discovery, anti-PDGFRβ treatment could soon be combined with existing tumor treatments to provide a more effective cancer therapy.

We described the case of an 82-year-old man diagnosed with recurrent MCC with cardiac and gastric metastasis who presented with poor oral intake and severe weight loss. The patient was diagnosed with MCC 3 years ago and treated with surgical resection and radiation. Interventions: We performed stomach biopsy in edematous lesion. And fluoroscopy and ultrasound guided biopsy of the cardiac mass was performed. Diagnoses: MCC with synchronous metastases to the heart and stomach. Outcomes: The primary lesion had complete resolution and the patient remained disease free on regular follow-up every 6 months for 2 and half...

Authors: Okazaki S, Shintani S, Hirata Y, Suina K, Semba T, Yamasaki J, Umene K, Ishikawa M, Saya H, Nagano O Abstract The cystine-glutamate antiporter subunit xCT suppresses iron-dependent oxidative cell death (ferroptosis) and is therefore a promising target for cancer treatment. Given that cancer cells often show resistance to xCT inhibition resulting in glutathione (GSH) deficiency, however, we here performed a synthetic lethal screen of a drug library to identify agents that sensitize the GSH deficiency-resistant cancer cells to the xCT inhibitor sulfasalazine. This screen identified the oral anesthetic dyclon...

CONCLUSIONS: Despite the implementation of IMRT, survivors of NPC still experience many physical symptoms that affect long-term QoL many years after treatment. Depression, anxiety, and fatigue remain common in long-term survivors and are highly correlated with QoL. PMID: 30191868 [PubMed - in process]

Narayana Subramaniam, Krishnakumar Thankappan, Adharsh Anand, Deepak Balasubramanian, Subramania IyerIndian Journal of Cancer 2018 55(1):4-8 The American Joint Committee on Cancer (AJCC) 8th edition marks a paradigm shift in the staging of head-and-neck cancers. It introduces several novel considerations into the staging of head-and-neck cancer, with distinct therapeutic ramifications, to stage and prognosticate patients better. In oral cancer, it introduces the depth of invasion as a determinant of T-stage. The nodal staging recommendations have also upstaged extranodal extension, which has been shown to be a high-risk a...

This article is concerned with the therapeutic index of chitosan nanoparticles against diethyl nitrosamine (DEN) induced hepatocellular carcinoma (HCC). HCC was induced in rats via repeated DEN administration in a dose of 200 mg/kg BW IP, 2 weeks later rats received (2 ml/kg BW) CCl4 orally for 2 months followed by daily treatment with chitosan nanoparticles in an oral dose of 12 mg/kg for 1 month. Then the gene expression of glycogen synthase kinase-3 (GSK-3), (c-FOS), nuclear factor kappa-B (NFκB) and tumor necrosis factor- α (TNF-α) were reported in rats sera and the correlation between GSK-3, C-...

ConclusionsClinicopathological features and survival outcomes in the PBM-treated patients were similar to previously published data for conventional treatments in patients with advanced OSCC. In this study, prophylactic use of PBM therapy did not impact treatment outcomes of the primary cancer, recurrence or new primary tumors, or survival in advanced OSCC patients.

Conclusion: This study showed weak positive correlation between mean eosinophils count in tumor and LNs. Recognition of TATE and MCs as integral to tumor biology opens an avenue for novel approaches to cancer therapies. We conclude that an increased number of immunological cells are a favorable prognostic indicator in OSCC.

Till 1998, a little was known about alternative forms of regulated cell death beside apoptosis. In present scenario, accumulating evidences suggest a form of programmed necrosis called Necroptosis which can be induced by various external stimuli including anticancer drugs, ionizing radiation, photodynamic therapy in the form of death domain receptor (DR) engagement by their respective ligands, TNF-alpha, Fas ligand (FasL) and TRAIL, under apoptosis deficient condition (caspase inhibitor),etc. receptor interacting protein-1 (RIP-1), a death domain containing kinase is the key molecule in necroptotic cell death pathway.
