Survival Outcome in True Carcinoma of Unknown Primary (tCUP) with p16 + Cervical Metastasis.

Introduction Age and lymph node ratio have been attributed as independent predictors for survival and recurrence in carcinoma of unknown primary (CUP). Objective The purpose of this study was to analyze the prognostic value of p16 overexpression for CUP in the absence of true primary (TP). Methods The study involved 43 patients who underwent therapeutic lymph node dissection (LND) from 2000 to 2015 after all the diagnostic work up for CUP. Immunohistochemistry for p16 overexpression was performed. Cox proportional hazard regression analysis was used to analyze the prognostic impact on 5-year overall survival (OS) and recurrence-free survival (RFS). Results The male-to-female ratio was 5.1:1, with a median age of 62 years. The clinicopathological data, except for p16 overexpression, did not differ significantly in terms of 5-year OS and RFS. The Cox regression analysis proposed p16 positivity to be an independent prognosticator of regional recurrence-free survival (RRFS) (hazard ratio [HR] 6.180, p = 0.21). The median time to recurrence and death were 10 and 25 months, respectively. Conclusion Cervical metastasis with p16 overexpression is a significant prognostic factor of improved RFS after surgery in CUP. The prognostic significance of lymph node p16 positivity should be further studied.

Carcinoma of Unknown Primary (CUP) versus CUP Turned to Primary Carcinoma of the Head and Neck-An Analysis of Diagnostic Methods and the Impact of Primary Tumor on Clinical Outcome.

BACKGROUND: The purpose of this study was to analyze the value of different diagnostic methods in detecting the primary site and the impact of primary tumors on the clinical outcome of carcinoma of unknown primary (CUP). METHODS: In this multicenter, retrospective study, 124 patients with true CUP (n = 94) and CUP turned to primary carcinoma (n = 30) were included. Patients with evidence of primary site during the clinical examination were excluded a priori. The diagnostic procedure was comprised of imaging and invasive methods (fine-needle-aspiration, tonsillectomy and panendoscopy). All patients were treated with curative intent. RESULTS: Despite extensive diagnostic workup, the primary site remained unknown in 75.8%. Invasive diagnostic methods showed higher primary detection rates than imaging modalities (15.1% vs. 7.8%). Tonsillectomy and panendoscopy revealed the primary tumor in 14.9% and 15.2% of patients, whereas the detection rates of CT, MRI and FDG-PET-CT were 10.1%, 4.8% and 6.5%, respectively. The occurrence of primary tumors led to a significantly deteriorating 5-year overall survival (p = 0.002) and emerged as survival prognosticator (HR = 2.764, p = 0.003). CONCLUSION: Clinical examination in combination with tonsillectomy and panendoscopy was superior to imaging alone in detecting the primary tumor. When the CUP of patients turned to a primary tumor, clinical outcome was significantly worse than in CUP patients.

[Beneficial outcomes of an interdisciplinary psychoeducative group intervention for patients with malignant gliomas and their relatives]. / Interdisziplinäre Psychoedukation für Hirntumorpatienten und deren Angehörige.

BACKGROUND: To assess the impact of psychoeducative group interventions on patients with high-grade glioma (glioblastoma, mixed glioma, and astrocytoma) and their relatives. METHODS: A total of one hundred and four patients and relatives underwent group interventions between September 2007 and May 2010 and were coached by a psychologist and a physician in the context of an interdisciplinary meeting. Questionnaires were distributed after every meeting. RESULTS: In general, group interventions were experienced as helpful to discuss psychic aspects, new life circumstances, and medical questions. CONCLUSIONS: Psychoeducative group interventions represent an important support for brain tumor patients and their relatives for discussing anxiety, concerns, and needs and thus improve their quality of life.
