Lesion regression rate based on RECIST: prediction of treatment outcome in patients with head and neck cancer treated with chemoradiotherapy compared with FDG PET-CT

The aim of this study was to evaluate whether the lesion regression rate (ΔLR) based on the Response Evaluation Criteria in Solid Tumors (RECIST) criteria could be used for the prediction of treatment outcome in head and neck squamous cell carcinoma (HNSCC) patients treated with chemoradiotherapy (CRT) compared with FDG PET-CT. A total of 33 patients underwent MRI and PET-CT at pretreatment and at 8 weeks after CRT. We assessed the treatment outcome by analyzing the following parameters: the RECIST criteria, ΔLR, the European Organization for Research and Treatment of Cancer (EORTC) criteria, and pretreatment SUV_max of the primary tumor and node. The correlation between the analysis of the parameters and the results of the long-term follow-up of the patients was determined. The RECIST did not significantly correlate with locoregional control (LRC) or survival. The ΔLR was significantly lower for the lesions with locoregional failure (LRF) than for those with LRC. A threshold ΔLR of 48% revealed a sensitivity of 72.7% and specificity of 77.3% for the prediction of LRF. Progression-free survival (PFS) of patients with ΔLR ≥ 48% was significantly better than that of patients with ΔLR < 48% (P = 0.001), but not overall survival. There was a significant correlation between LRC and the EORTC (P = 0.02). The patients who achieved a complete response by the EORTC criteria showed significantly better PFS and overall survival (P = 0.01 and 0.04, respectively). The ΔLR was inferior to FDG PET-CT with respect to the prediction of patient survival; however, it may be useful for selecting patients in need of more aggressive monitoring after CRT.     

A 4‐year follow‐up case of extrusive luxation in a patient with cerebral palsy

Cerebral palsy (CP) is a condition caused by brain damage before, during, or shortly after birth. Communication can be a challenge when treating patients with CP. Some patients can communicate verbally, while others use augmentative alternative communication tools or have individualized means of communication. Therefore, professional dental treatment in individuals with CP is challenging, especially if the patient is affected by dental trauma and requires emergency treatment. This report shows how individualized communication skills assessment allowed us to successfully manage a 9‐year‐old patient with CP, who suffered extrusive luxation of the permanent lower incisor. In the present case, the teeth were repositioned briefly after the trauma had occurred and then stabilized with a flexible splint according to international guidelines. The teeth remained vital and periodontal repair was observed during the 4‐year follow‐up.     

The long-term influence of hospital and surgeon volume on local control and survival in the randomized German Rectal Cancer Trial CAO/ARO/AIO-94

BackgroundThe association of treatment volume and oncological outcome of rectal cancer patients undergoing multidisciplinary treatment is subject of an ongoing debate. Prospective data on long-term local control and overall survival (OS) are not available so far. This study investigated the long-term influence of hospital and surgeon volume on local recurrence (LR) and OS in patients with locally advanced rectal cancers.MethodsIn a post-hoc analysis of the randomized phase III CAO/ARO/AIO-94 trial after a follow-up of more than 10 years, 799 patients with stage II/III rectal cancers were evaluated. LR-rates and OS were stratified by hospital recruitment volume (≤20 vs. 21–90 vs. >90 patients) and by surgeon volume (≤10 vs. 11–50 vs. >50 procedures).ResultsPatients treated in high-volume hospitals had a longer OS than those treated in hospitals with medium or low treatment volume (p = 0.03). The surgeon volume was adversely associated with LR (p = 0.01) but had no influence on overall survival. The positive effect of neoadjuvant chemoradiation (CRT) on local control was the strongest in patients being operated by medium-volume surgeons, less in patients being operated by high-volume surgeons and missing in those being operated by low-volume surgeons.ConclusionsPatients with locally advanced rectal cancers might benefit from treatment in specialized high-volume hospitals. In particular, the surgeon volume had significant influence on long-term local tumour control. The effect of neoadjuvant CRT on local tumour control may likewise depend on the surgeon volume.     

Patient Perspectives on Benign Prostatic Hyperplasia Surgery: A Focus on Sexual Health

BackgroundIn the last decade, many novel minimally invasive surgical techniques within benign prostatic hyperplasia (BPH) surgery were developed to reduce postoperative complications that often discourage patients from pursuing BPH surgery.AimTo assess perspective of future and past international BPH surgery patients regarding their postoperative complications, namely erectile and ejaculatory function.MethodsA survey was distributed randomly to 2 groups of BPH patients: one with 149 patients having undergone surgery in the last 2 years (group A), and the other cohort of 151 men seriously considering BPH surgery in the next year (group B). This survey consisted of 20 questions that assessed patients' motivating factors for undergoing elective BPH surgery and their perspectives regarding the potential postoperative complications attributed to BPH surgery.OutcomesThe perspective of future and past international BPH surgical patients towards the preservation of their erectile and ejaculatory functions was assessed with the help of a survey.ResultsResults indicated that in general BPH surgery patients considered the maintenance of erectile (95%, n = 284) and ejaculatory function (92%, n = 276) to be important preoperative considerations, regardless of their age. Patients aged 50–59 years were most concerned with the permanent impact on sexual function and patients aged >60 years were most concerned with urinary incontinence. In patients aged >70 years, 66% (n = 43) and 62% (n = 40) of the respondents indicated that maintaining erectile and ejaculatory function was important, respectively.Clinical ImplicationsPatient-centered care needs to be implemented in order to address the importance that past and future BPH surgery patients hold toward the maintenance of their postoperative sexual function.Strengths & LimitationsIn the group of patients having previously undergone BPH surgery, the possibility of recall bias should be taken into account when interpreting the study's findings. However, maintaining sexual function was also important for the group of patients seriously considering surgery in the next year suggesting that these considerations are not solely due to recall bias. Additionally, the results were limited by the small sample size of participants in groups A (n = 149) and B (n = 151).ConclusionIt was found that past and future BPH surgery patients attribute a significant importance toward the maintenance of their sexual function. Although novel approaches with better sexual outcomes such as Rezum and UroLift for prostates <80 mL, and Aquablation for any size prostate are available, more research is needed to investigate their long-term effects on sexual function before they can be recommended to patients.Bouhadana D, Nguyen D-D, Zorn KC, et al.

Baseline immune activation as a risk factor for the onset of depression during interferon-alpha treatment.

BACKGROUND: Major depression has been associated cross-sectionally with increased cell-mediated immune activation but causality has been difficult to establish. This study prospectively investigated the hypothesis that baseline level of immune activation predicts the development of depression during interferon-alpha (IFN-alpha) treatment. METHODS: Sixteen hepatitis C patients without psychiatric disorder underwent IFN-alpha treatment. Proinflammatory and anti-inflammatory cytokines were determined before starting treatment. Presence of a major depressive disorder (MDD) was assessed at baseline and several times during treatment. RESULTS: Baseline soluble interleukin-2 receptor (sIL-2r), interleukin-6 (IL-6), and interleukin-10 (IL-10) concentrations were significantly increased in the five subjects that developed MDD during treatment compared with those that did not, with standardized effect sizes of 1.08, 1.16, and 1.25, respectively, controlling for marijuana use, cigarette smoking, and baseline level of depressive symptoms. CONCLUSIONS: Results suggest that increased immune activation, rather than an epiphenomenon, is a causal risk factor for the development of MDD.
