New Therapeutic Strategies in the Treatment of Stomal Recurrence After Total Laryngectomy: Role of Immunotherapy
Full text linkObjective: The aim of this study was to investigate the incidence of stoma recurrence and the therapeutic strategy outcomes in relation to survival that have been adopted over the past few decades using a monoclonal antibody, specifically nivolumab. Methods: This study included a total of 487 patients diagnosed with laryngeal carcinoma undergoing either a laryngectomy or salvage surgery after conservative interventions at the ENT Unit of Federico II University in Naples, Italy, between 2011 and 2021. Following a minimum 2.5-year follow-up and a maximum 21-year follow-up, the results revealed that only 38 patients suffered a stomal recurrence. Results: Despite various adopted treatment strategies, the literature reports lower patient survival rates. Following a total laryngectomy, stomal recurrence represents a therapeutic management challenge due to a poor prognosis for nearly every treated case. According to the literature, in fact, despite a low incidence (ie, 0.8–31.3%), the overall mortality rate increases from 77% to 100% after three years. Nevertheless, introducing immunotherapy into cancer treatment has resulted in an observable revolution in the treatment of different types of cancers over the years. Conclusion: In light of recorded data on survival following the use of the nivolumab, the case presented in this study allows a new perspective of successfully treating recurrences of squamous carcinoma of the head and neck. © The Author(s) 2022

Digital ischemia in patIents with solid tumors: a case report and review of the literature
No full textDigital ischemia is a rare paraneoplastic phenomenon associated with various malignancies, especially adenocarci-nomas. We reported a case of digital ischemia onset during treatment with capecitabine + oxaliplatin, letrozole and epoetin-beta in a 75-year old woman with colon and breast cancer and a secondary hepatic lesion.
A literature review disclosed 68 cases of solid neoplasms associated with digital ischemia. The proposed mechanisms of such clinical manifestations are various: vasospasm due to sympathetic hyperactivity, arteritis induced by tumour antigen-antibody complexes deposition or as consequence of immune deregulation, blood hyperviscosity, hypercoagulability or peripheral thrombosis. In the present case, clinical and laboratory evaluations failed to reveal evidence of thrombosis, arteritis, inherited or acquired hypercoagulable state and we postulated the peripheral vasospasm and the sympathetic activity (possibly due to chemotherapy drugs) as potential causes of the digital ischemia
Total metabolic tumor volume by 18F-FDG PET/CT for the prediction of outcome in patients with non-small cell lung cancer
No full textObjective Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) are imaging parameters derived from 18F-FDG PET/CT that have been proposed for risk stratification of cancer patients. The aim of our study was to test whether these whole-body volumetric imaging parameters may predict outcome in patients with non-small cell lung cancer (NSCLC). Methods Sixty-five patients (45 men, 20 women; mean age +/- SD, 65 +/- 12 years), with histologically proven NSCLC who had undergone 18F-FDG PET/CT scan before any therapy, were included in the study. Imaging parameters including SUVmax, SUVmean, total MTV (MTVTOT) and whole-body TLG (TLG(WB)) were determined. Univariate and multivariate analyses of clinical and imaging variables were performed using Cox proportional hazards regression. Survival analysis was performed using Kaplan-Meier method and log-rank tests. Results A total of 298 lesions were analyzed including 65 primary tumors, 114 metastatic lymph nodes and 119 distant metastases. MTVTOT and TLG(WB) could be determined in 276 lesions. Mean value of MTVTOT was 81.83 ml +/- 14.63 ml (SE) whereas mean value of TLG(WB) was 459.88 g +/- 77.02 g (SE). Univariate analysis showed that, among the variables tested, primary tumor diameter (p = 0.0470), MTV of primary tumor (p = 0.0299), stage (p 54.7 g (p 9.5 ml (p < 0.0001). Similar results were obtained in a subgroup of 43 patients with advanced disease (stages III and IV). Conclusions Whole-body PET-based volumetric imaging parameters are able to predict outcome in NSCLC patients
alpha-Interferon potentiates the growth inhibitory effects of anti-transferrin receptor monoclonal antibodies
No full textWe have demonstrated that interferon-alpha 2 recombinant (IFN alpha) inhibits the growth and modulates the expression of the receptor for transferrin (TRF-R) in human epidermoid carcinoma KB cells. Receptor upregulation results in the reconstitution of intracellular iron levels in the IFN alpha-treated cells. Several anti-TRF-R murine monoclonal antibodies (MAbs) have been generated which induce tumor cell growth inhibition through blockade of receptor function. We have evaluated by MTT assay the effect of anti-TRF-R 42/6, E2.3, A27.15 and D65.30 MAbs given in combination with IFN alpha on the growth of human epidermoid carcinoma KB cells. We found that IFN alpha and A27.15 MAb induced a synergistic antiproliferative effect on these cells. These results suggest that IFN alpha may potentiate the antitumor efficacy of TRF-R-targeted therapy
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
