Prognostic value of pretreatment circulating neutrophils, monocytes, and lymphocytes in oropharyngeal cancer stratified by human papillomavirus status.

BACKGROUND: The objective of this study was to investigate the prognostic value of the pretreatment circulating neutrophil count (CNC), circulating monocyte count (CMC), and circulating lymphocyte count (CLC) in human papillomavirus (HPV)-related (HPV+) and HPV-unrelated (HPV-) oropharyngeal cancer (OPC). METHODS: All p16-confirmed HPV+ and HPV- OPC cases treated with chemoradiotherapy from 2000 to 2010 were included. Overall survival (OS) and recurrence-free survival (RFS) were compared for high and low CNCs, CMCs, and CLCs (dichotomized by median values). A multivariate analysis (MVA) confirmed their prognostic value in HPV+ and HPV- tumors, respectively. RESULTS: Five hundred ten HPV+ OPC cases and 192 HPV- OPC cases were included. The HPV+ cohort had lower CNC and CMC values but a CLC similar to that of the HPV- patients (P < .01). The median follow-up was 4.8 years. In the HPV+ cohort, a high CNC or CMC correlated with reduced OS and RFS in comparison with a low CNC or CMC (P < .01 for all), but no difference was evident in OS (P = .30) or RFS (P = .10) with the CLC. MVA confirmed that a higher CNC or CMC independently predicted lower OS (hazard ratio [HR] for CNC, 1.14, P < .01; HR for CMC, 2.95, P < .01) and lower RFS (HR for CNC, 1.11, P < .01; HR for CMC, 3.39, P < .01), whereas a higher CLC was associated with higher RFS (HR, 0.66, P = .03) and marginally higher OS (HR, 0.80, P = .08). In the HPV- cohort, CNC, CMC, and CLC were not predictive of OS (P = .16, P = .86, and P = .14) or RFS (P = .61, P = .59, and P = .62). CONCLUSIONS: This relatively large cohort study demonstrates that a high CNC and a high CMC independently predict inferior OS and RFS, whereas a high CLC predicts better RFS and marginally better OS in HPV+ OPC patients. This association was not apparent in HPV- patients.

Neural autoantibody clusters aid diagnosis of cancer.

PURPOSE: Clustering of neural autoantibodies in patients with paraneoplastic neurologic disorders may predict tumor type. A mathematical analysis of neural autoantibody clusters was performed in 78,889 patients undergoing evaluation for a suspected paraneoplastic autoimmune neurologic disorder. Tumor predictive autoantibody profiles were confirmed in sera from patients with histologically proven tonsillar cancer, thymoma, and lung cancer. PATIENTS AND METHODS: Of note, 78,889 patient sera were tested for 15 defined neural autoantibodies (1.2 million tests). The observed and hypothesized frequencies of autoantibody clusters were compared and their tumor associations defined. A tumor validation study comprised serum from 368 patients with a variety of tumors (thymoma, lung, or tonsil). RESULTS: Informative oncological associations included (i) thymoma in 85% of patients with muscle striational, acetylcholine receptor antibodies plus CRMP5 autoantibodies; (ii) lung carcinoma in 80% with both P/Q-type and N-type calcium channel antibodies plus SOX1-IgG; and (iii) in men, prostate carcinoma frequency more than doubled when striational and muscle AChR specificities were accompanied by ganglionic AChR antibody. In women, amphiphysin-IgG alone was associated commonly with breast carcinoma, but amphiphysin-IgG, coexisting with antineuronal nuclear autoantibody-type 1 or CRMP5-IgG, was associated with lung cancer (P < 0.0001). In the validation cohorts, many tumor-associated profiles were encountered that matched the clusters identified in the screening study (e.g., 15% of thymoma patients had striational, acetylcholine receptor antibodies plus collapsin response-mediator protein-5 autoantibodies). CONCLUSIONS: Neural autoantibodies commonly coexist in specific clusters that are identifiable by comprehensive screening. Signature autoantibody clusters may predict a patient's cancer risk and type.

[Postoperative therapy of an alcoholic patient with an unusually high ethanol metabolic rate]. / Postoperative Therapie eines alkoholkranken Patienten mit ungewöhnlich gesteigerter Ethanolabbaurate.

To avoid alcohol withdrawal syndrome (AWS) a pre-operative withdrawal, post-operative drug therapy or continued substitution of ethanol may be tried. However, substitution of ethanol needs an exact dosage and has to be controlled very carefully. The dose calculation is based on an assumed breakdown rate of 0.15 g%/1000/h, as evaluated in forensic studies. We report on a patient who throws the basis for these calculations into question. The breakdown rate of this 43-year-old man was extraordinary higher than the average turnover. This high level of the turnover rate occurred with no detectable impairment of the liver or other organs. This case demonstrates the importance of a close control of the blood alcohol level during the post-operative administration of ethanol. The individual doses of ethanol to avoid AWS has to be found individually for each patient.

Pregnancy and relapse of peripheral T cell lymphoma. A case report.

A patient was admitted to our hospital, in the 34th week of her pregnancy, who presented a non-Hodgkin lymphoma. The delivery was induced in the 38th week and the newborn baby had no other anomalies than a single umbilical artery and a slight dilation of the cerebral ventricles which receded spontaneously. Peculiar characteristics, not previously described, were a peripheral T cell lymphoma with relapse after 5 years since its remission with chemotherapy.

[Role of the tumor marker TAG-72 in head and neck neoplasms]. / Zur Rolle des Tumormarkers TAG-72 in den Neoplasien des Kopf-Hals-Bereiches.

The serum glycoprotein TAG-72 level was determined in 34 patients with chronic laryngitis or ENT malignancy. This marker is in widespread use in cases of gynaecological and gastrointestinal malignancy. TAG-72 levels did not differ significantly either from the levels of healthy subjects or in the post-operative follow-up, so that this indicator appears to be of no clinical value in head and neck oncology.
