Summary Background Population aging strongly affects the demographic development of industrialized countries. While microsurgical procedures were initially believed to be only feasible in patients of younger age because of the duration of the surgical procedure and the higher risk of vascular insufficiency due to age-related comorbidities, it has become evident that these procedures are beneficial even for patients at an advanced age. Methods We retrospectively investigated microsurgical procedures in a patient cohort ( n = 25 with 27 free flaps) with a minimum age of 78 years with regard to patients' characteristics, flap survival, and postoperative surgical and medical complications. Results Median age was 81 years (IQR 6). Most defects were located in the head and neck region. The mean operation time was 384 min (standard deviation (SD) 131). Flap failure was observed in three cases (11%). The median length of hospital stay was 17 days (interquartile range (IQR) 8). The mean ASA score was 2.48. Patients' age and ASA group did not correlate. The mortality rate was 4%. Postoperative surgical complications were observed in 11 cases (41%), while 19 patients (70%) showed one or more medical complications. Higher ASA classes tended to show more postoperative complications. However, neither age nor operating time nor ASA status showed significant influence on the occurrence of postoperative medical or surgical complications. Conclusion There is growing demand for structural and functional restoration using free tissue transfer in an aging population. If there are no alternative treatment options available promising similar structural and functional preservation, free tissue transfer is justifiably in very old patients despite a potentially increased flap failure. As such, free tissue transfer is used as a curative treatment concept aiming at a maximum of patients' independence and early ambulation. Occurrence of complications can be diminished by adequate patient selection and thorough perioperative care. [ABSTRACT FROM AUTHOR]

Objectives: Analysis of long-term speech and swallowing function and subjective quality of life (QOL) after primary resection and sentinel node biopsy (SNB) in patients with early stage (cT1/T2) oral squamous cell carcinomas (OSCC).Material and Methods: Eighty-one consecutive patients treated primarily by transoral resection without flap reconstruction and SNB for a cT1/T2 OSCC were included. Completion neck dissection (CND) was indicated in case of occult disease in the sentinel nodes. Adjuvant radiation (aRT) was administered according to the ultimate lymph node status. All patients showed no evidence of disease at time of analysis. Speech and swallowing function were assessed using standardized clinical examinations (11-item, articulation test) and validated questionnaires on subjective QOL (MDADI, FIGS). Median follow-up was 60 months (range 13-159 months) after initial treatment.Results: In all assessments for speech and swallowing, the entire study cohort achieved very high scores, with mean values located in the highest 10% of the scales. Neither tumor size nor site, age, pN-category, CND, and aRT had significant impact on functional outcomes and subjective QOL with the exception of lower scores in the global and physical scores of MDADI after CND or aRT, and articulation in the population over 60 years of age.Conclusion: Transoral resection without reconstruction and SNB for early OSCC achieves excellent outcome with regard to speech, swallowing and subjective QOL.

Abstract: Background: The transcription factor sex determining region Y (SRY)-box 2 (SOX2) (3q26.3–q27) has been recently identified as a recurrently activated major oncogene in squamous cell carcinoma of various sites. Its prognostic value in head and neck squamous cell carcinoma (HNSCC) is currently unclear. Aim: To correlate SOX2 protein expression with the occurrence of occult lymph node metastasis and relapse free survival in early oral SCC. Methods: SOX2 expression in 120 T1/T2 oral SCC patients was evaluated using a tissue microarray technique. Intensity of SOX2 expression was quantified by assessing the Intensity/Reactivity Scores (IRSs). These scores were correlated with the lymph node status of biopsied sentinel lymph nodes and recurrence. Log rank univariate and Cox regression multivariate analysis was used to determine statistical significance. Results: Twenty-six of 120 primary tumours (21.7%) showed high SOX2 expression. High expression levels of SOX2 significantly correlated with negative lymph node status in univariate (p =0.001) and multivariate analysis (p =0.003). Sensitivity was found to be 95.6% with a negative predictive value of 92.3%. Specificity was 32% with a positive predictive value of 45.7%. Conclusion: SOX2 up-regulation is frequent in early SCC of the oral cavity and associated with decreased risk of lymphatic metastasis. SOX2 immunohistochemistry may be used as a predictor for lymph node metastasis in squamous cell carcinoma of the oral cavity. [Copyright &y& Elsevier]
