Postoperative Radiochemotherapy Using Modern Radiotherapy Techniques in Elderly Patients with Head and Neck Squamous Cell Carcinoma: The Challenge of Weighing Up Benefits and Harms of Treatment Modalities in Clinical Practice.

Locally advanced head and neck squamous cell carcinomas (HNSCC) are often managed with surgery followed by postoperative radiochemotherapy (RCT). With the general increase in life expectancy, the proportion of elderly patients with HNSCC is expected to grow rapidly. Until now, a deeper understanding of specific management strategies for these patients in clinical routine was lacking. In the present study, we compared elderly patients (≥70 years, n = 52) and younger patients (n = 245) treated with postoperative RCT for HNSCC at our tertiary cancer center. All patients were irradiated with modern radiotherapy techniques (IMRT/VMAT). Patients ≥70 years of age had more comorbidities. Additionally, elderly patients less frequently received concomitant systemic treatment. The rates of mucositis and dermatitis were lower in patients ≥70 years. Elderly patients had significantly worse overall and progression-free survival. Locoregional and distant control were comparable in elderly and younger patients. In conclusion, postoperative RCT is a safe and effective treatment option in patients ≥70 years. In light of comorbidities and poor overall survival rates, benefits and harms of radiotherapy and concomitant systemic treatment should be weighed carefully. When exclusively applying up-to-date radiotherapy techniques with, at the same time, careful use of concomitant systemic therapy, favorable acute toxicity profiles are achieved.

Evaluation of ustekinumab trough levels during induction and maintenance therapy with regard to disease activity status in difficult to treat Crohn disease patients.

ABSTRACT: Ustekinumab (UST) is approved for the treatment of moderate and severe Crohn disease (CD). Therapeutic drug monitoring (TDM) can help monitor the therapeutic effects of biologics. Therefore, the aim of this study was to evaluate the clinical outcomes of UST-treated CD patients and to determine the UST trough level in clinical and corticosteroid-free remission.This retrospective study included patients with moderate and severe active disease (AD) treated intravenously with a weight-adapted induction dose of UST. The maintenance therapy consisted of 90 mg UST subcutaneously at week 8 and thereafter every 8 or 12 weeks, depending on the clinical response. Clinical and corticosteroid-free remission, Harvey-Bradshaw-Index (HBI), UST trough level, and further laboratory parameters were measured just before the injection of UST at each follow-up evaluation until week 40.37 CD patients with a median HBI of 9 at week 0 were included in the study. Starting from 24% at the beginning of the monitoring period, and 38% of patients at the end of the monitoring period were treated with an 8-week interval (P = .18). There was a significant improvement in clinical (P = .0004), corticosteroid-free remission (P = .03), and HBI (P < .0001) from week 0 until the end of the observation period. The serum UST trough level decreased significantly from 2.0 at week 8 to 0.3, in the maintenance therapy and 0.4 µg/ml at the end of the therapy (P < .0001). Neither UST trough level nor levels of C-reactive protein (CRP) or fecal calprotectin (FC) were associated with disease outcome. Concomitant immunomodulator therapy did not appear to affect the UST trough level or clinical course.UST is an effective treatment option for difficult-to-treat patients with CD. UST trough levels may not be associated with treatment efficacy or the prediction of treatment outcomes in patients with CD. Further prospective randomized trials should be conducted to evaluate whether UST trough levels are associated with treatment outcomes in patients with CD.

Association of serum interleukin-6 and soluble interleukin-2-receptor levels with disease activity status in patients with inflammatory bowel disease: A prospective observational study.

Crohn's disease (CD) and ulcerative colitis (UC) are characterized by overexpression of proinflammatory cytokines. We determined the association of serum levels of interleukin (IL)-6, soluble-IL-2-receptor (sIL-2R) and CRP as well as of faecal calprotectin (FC) values with disease activity in CD and UC patients. This prospective study included 145 CD and 84 UC patients. Serum proinflammatory biomarkers and FC levels were measured and demographic, clinical and endoscopic characteristics were collected. Uni- and multivariate statistical analyses were performed. Serum IL-6 and CRP levels as well as FC values of CD patients were associated with clinical and endoscopic remission. In multivariate analysis serum IL-6 levels remained significantly associated with clinical and endoscopic remission. FC levels were also associated with endoscopic remission in CD patients. CD patients under the threshold levels of 8.5 pg/mL and 5.5 pg/mL for serum IL-6 were in 70% and 66% in clinical and endoscopic remission, respectively. Serum sIL-2R, CRP levels and FC values of UC patients were associated in univariate analysis with clinical and endoscopic remission. In multivariate analysis CRP and FC values were associated with clinical remission and serum sIL-2R as well as FC levels with endoscopic remission. UC patients under the threshold levels of 759 IU/mL and 646 IU/mL for serum sIL-2R were in 76% and 76% in clinical and endoscopic remission, respectively. Beside CRP and FC, serum IL-6 levels in CD patients and sIL-2R levels in UC patients can be a further useful non-invasive biomarker to identify the disease activity status.

Quality of life in patients after reconstruction with the supraclavicular artery island flap (SCAIF) versus the radial free forearm flap (RFFF).

PURPOSE: Gold-standard for defect reconstruction in the head and neck region is the radial free forearm flap (RFFF). The supraclavicular artery island flap (SCAIF) gained popularity due to its versatility. Our objective was to compare functional advantages between both modalities. METHODS: A retrospective analysis of 24 consecutive cases with advanced-stage squamous cell cancer of the oral cavity and oropharynx after cancer defect reconstruction with two modalities (12 SCAIF; 12 RFFF) was conducted. Patients completed the European Organization for Research and Treatment of Cancer (EORTC) questionnaires, Quality of Life Questionnaire-Core 30-questions (QLQ-C30) and Quality of Life Questionnaire-Core 30 Head and Neck 35-questions (QLQ-H&N35). RESULTS: Mean follow-up was 22.2 ± 9.5 months. Comparison of quality of life (QOL) showed significant differences only in speech and problems with the senses in favor of the SCAIF. CONCLUSION: Patients report satisfactory QOL results after oncologic surgery and reconstruction with preliminary no significant differences in most aspects comparing the two modalities. Therefore, the SCAIF appears as a viable alternative to the gold standard, the RFFF.

Shoulder Morbidity in Patients after Head and Neck Reconstruction with the Pedicled Supraclavicular Island Flap.

BACKGROUND: The pedicled supraclavicular artery island flap (SCAIF) for reconstruction of the head and neck has been shown to be a pliable alternative to established pedicled flaps, such as the pectoralis major myocutaneous flap. Because there are limited published data regarding shoulder morbidity after SCAIF procedure, we aimed to investigate it with 2 established questionnaires for the upper extremity [Constant-Murley score and Disabilities of the Arm, Shoulder and Hand Outcome Measure (DASH) score]. METHODS: The authors designed and implemented a retrospective cohort study of patients who received a defect reconstruction by SCAIF. Analyzed parameters were demographics, comorbidities, donor-site morbidity and shoulder morbidity in terms of range of motion, pain, strength, and daily activities evaluated and compared between the donor site and contralateral arm. RESULTS: Of the 61 consecutively performed head and neck reconstructions with SCAIF, 20 met inclusion criteria (curative intended treatment, head and neck squamous cell cancer, follow-up time more than 4 months). Mean follow-up was 17.3 months (±10.4 months) ranging from 4-35 months. Donor-site complication rate was low with 5% major (surgical revision) and 30% minor complications (conservative management). Overall Constant-Murley-Score (P = 0.334), pain (P = 0.150), overall range of motion (P = 0.861), and strength of the extremity (P = 0.638) of the shoulder receiving a SCAIF showed no significant differences to the contralateral extremity. Mean of Disabilities of the Arm, Shoulder and Hand Outcome Measure score was 32.5 (±28.6). CONCLUSION: The results of the present study suggest very low shoulder morbidity in patients after SCAIF procedure with no significant functional impairment of the donor shoulder compared with the contralateral side.

Oral Cancer Reconstruction Using the Supraclavicular Artery Island Flap: Comparison to Free Radial Forearm Flap.

PURPOSE: To evaluate whether the pedicled supraclavicular artery island flap (SCAIF) is a sufficient alternative to the fasciocutaneous radial forearm free flap (RFFF) for oral reconstruction in cancer surgery. PATIENTS AND METHODS: The authors designed and implemented a retrospective cohort study composed of all consecutive patients who underwent head and neck reconstruction after cancer surgery at their tertiary university hospital from 2013 to 2016. Demographics and peri- and postoperative information were recorded and statistically analyzed. RESULTS: Of 83 patients who underwent head and neck reconstruction after cancer, 50 were identified as having stage III or IV squamous cell carcinoma of the oral cavity and oropharynx and underwent surgery and reconstruction with the SCAIF (n = 25) or the RFFF (n = 25). Total surgery time (411.0 vs 576.4 minutes; P < .001), flap elevation time (39.00 vs 93.78 minutes; P < .001), need for intensive care observation (32 vs 96%; P < .05), and rate of tracheotomy (64 vs 88%; P < .05) were significantly lower in the SCAIF group. There was no statistical difference in the postoperative complication rate or postoperative functional swallowing ability between the 2 groups. Total perioperative costs were significantly lower in patients who underwent reconstruction with the SCAIF (2,621.15 vs 4,453.77€; P < .01). CONCLUSION: The results of this study suggest that the SCAIF is a straightforward and reliable flap with shorter operative times and comparable outcomes compared with the RFFF.

Transoral laser microsurgery for T1b glottic cancer: review of 51 cases.

For the treatment of T1b glottic carcinoma, different treatment options, such as transoral laser microsurgery, open surgical techniques, and primary radiotherapy, are under discussion. In this context, the aim of the present study was to describe oncologic results and complication rates of transoral laser microsurgery in treatment of T1b glottic carcinoma. This is a retrospective unicenter chart review of patients treated at an academic tertiary referral center between 1986 and 2006. Fifty-one previously untreated T1b cases were exclusively treated by transoral laser microsurgery and included into this study, 47 were male, and 4 were female. The main outcome measures included local control rate and complications, overall, disease specific, and recurrence-free survival. The median follow-up period was 98 months. The 5-year local control rate was 90.2%; larynx preservation rate was 92.2%. No intra- or postoperative complications, such as wound infections, postoperative bleeding, hematoma, edema, and fistula development, were observed. A single patient required revision surgery due to synechia. Five-year survival rates were: overall 84.7%, disease specific 97.7%, and recurrence free 72.4%. Our data support the conclusion that transoral laser microsurgery is a considerable treatment option in T1b glottic carcinoma. The oncologic outcome was at least comparable to other treatment options, while the perioperative morbidity and complication rate were lower.

Eustachian tube communicating with sphenoid sinus: report of a novel anatomical variant.

Reports of congenital anomalies of the Eustachian Tube (ET) are scarce, and often associated with chromosomal abnormalities. We report a unique case of a completely bony left Eustachian tube which communicated with the sphenoid sinus. This report details these findings and discusses the potential embryological basis and implications of such an unusual anatomy, in the context of a comprehensive literature review.

What factors influence British medical students' career intentions?

AIM: The aim of this study was to identify factors that influence career choice in UK medical students. METHODS: Students at seven institutions were invited to rate how important various factors were on influencing their career choices and how interested they were in pursuing different specialties. The influence of interpersonal relationship networks on career choice was also evaluated. RESULTS: 641 responses were collected. 44% (283) were male, 16% (105) were graduates and 41% (263) were final-year students. For Dermatology (p = 0.009), Paediatrics (p = 0.000), Radiology (p = 0.000), Emergency Medicine (p = 0.018) and Cardiothoracic Surgery (p = 0.000), there was a clear correlation between completing a clinical attachment and an interest in pursuing the specialty. Perceived characteristics of the speciality, individually and in clusters were considered important by specific subgroups of students, such as those interested in surgery. These students considered prestige (p = 0.0003), role models (p = 0.014), financial rewards after training (p = 0.0196) and technical challenge (p = 0.0011) as important factors. Demographics such as sex and age played a significant role in career choice. Interpersonal relationship networks do not have a significant influence on career intentions. CONCLUSIONS: This study shows that the career intentions of British medical students are influenced by their undergraduate experience and by the weight they place on different specialty-related factors.
