Patients with Heart Failure During and After Inpatient Cardiac Rehabilitation.

BACKGROUND: Heart failure is the third most fatal disease in Germany and generates considerable treatment costs. The multimodal program of inpatient rehabilitation can improve the symptoms and prognosis of these patients. At the present time, however, only few data are available on the effectiveness of rehabilitation for heart failure patients. METHODS: After receiving study approval from the ethics committee of the Saxony-Anhalt Medical Association, 200 patients with a primary or secondary diagnosis of heart failure were prospectively included in the study at Paracelsus-Harz-Clinic Bad Suderode, Quedlinburg, Germany. Baseline parameters such as age, gender, and BMI were documented. Outcome variables included NYHA classifications, quality of life, and mortality. For follow-up, the patients were contacted again by mail or phone after three and 12 months and, data on symptoms and serious events were recorded. RESULTS: The proportion of patients with a highly reduced ejection fraction (HFrEF) was 13.5%, with a midrange reduced ejection fraction (HFmrEF) 33%, and with preserved ejection fraction (HFpEF) 53.5%. The mean age was 64 ± 11.9 years, the proportion of women 24.1%. The effects of rehabilitation were documented by low overall mortality (no patient died during the stay, only 4% of the patients died in the 12-month follow-up) and an improvement in NYHA classification during and after the inpatient rehabilitation. CONCLUSION: This monocentric study showed effects both for symptoms (improvement in NYHA classifications) and prognosis (overall mortality) after rehabilitation. These data reflect the effectiveness of multimodal rehabilitation and underscore the need for rehabilitation in patients diagnosed with heart failure after an acute event and hospital stay or who present with chronic deterioration.

Evaluation of the Aortopathy in the Ascending Aorta: The Novelty of Using Matrix-Assisted Laser Desorption/Ionization Imaging.

PURPOSE: Histopathological evaluation presents conflicting reports regarding aortic abnormalities. The authors aim to present proof-of-concept study to explore the feasibility of matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) in combination with histopathology for characterizing alterations in the aneurysmal ascending formalin-fixed paraffin-embedded (FFPE) aorta tissue. EXPERIMENTAL DESIGN: The authors assess FFPE specimens from patients with a dilated aorta and bicuspid aortic valve (BAV), those with a standard tricuspid aortic valve (TAV), and those with Marfan syndrome (MFS) via histopathology and grade the conditions for elastic fiber fragmentation (EFF) and MALDI-IMS. The proteins using liquid chromatographic-mass spectrometry are identified and the results are confirmed by immunohistochemistry. RESULTS: There is significant difference in terms of EFF between MFS and BAV, and TAV and BAV. Characteristic peptide signatures and m/z values in the EFF facilitate the characterization among the aortic specimens of BAV, MFS, and TAV. The m/z values from the aortic alpha smooth muscle actin and myosin heavy chains significantly increase in BAV compared with MFS and TAV. These findings are confirmed by immunohistochemistry. CONCLUSION: The results represent a strategy that uses MALDI-IMS in combination with histopathology as promising approaches to characterize spatial alteration in the structure of the aneurysmal ascending aorta.

[Health-Related Quality of Life in Patients with Non-Small Cell Lung Cancer before and after Surgery - a Comparison between Thoracotomy and Video-Assisted Thoracoscopic Surgery]. / Untersuchungen zum Verlauf der Lebensqualität vor und bis 2 Jahre nach anatomischer Resektion bei Patienten mit Lungenkarzinom ­ ein Vergleich zwischen anterolateraler Thorakotomie und videoassistierter Thorakoskopie.

BACKGROUND: Earlier studies have proven that in patients with non-small cell lung cancer video-assisted thoracoscopic surgery is functionally superior to thoracotomy in terms of perioperative and postoperative complications. The objective of this work was to determine whether there is a difference in health-related quality of life (HRQoL) of patients with non-small cell lung cancer - compared to the German normal population - before and after surgery. Moreover, HRQoL after thoracotomy was compared to HRQoL after video-assisted thoracoscopic surgery (VATS). MATERIAL AND METHODS: Based on retrospective data generated during a 7-year period (2010 - 2017), 327 patients with non-small cell lung cancer who underwent therapy were examined. Patients either underwent thoracotomy or video-assisted thoracoscopic surgery. 456 of short form 12 questionnaires were analysed. Via norm-based scoring, and physical and mental component summaries (PCS and MCS) were calculated before and 6, 12, and 24 months after treatment. Using t tests, potential differences in physical and mental component summaries were evaluated between patients and the German normal population as well as between patients after thoractomy and after VATS. RESULTS: Up to 24 months after surgery, the physical dimension of HRQoL is significantly reduced, while the mental component summary does not significantly differ from the German population. Moreover, thoracotomy and VATS gave equivalent values for health-related quality of life. CONCLUSION: With respect to health-related quality of life, thoracotomy and video-assisted thorascopic surgery are equivalent in the long term. But there was a trend to improvement with both summary scores that might indicate superiority of video-assisted thoracoscopic surgery.

Adherence To Lipid-Lowering Therapy In Patients With Coronary Heart Disease From The State Of Saxony-Anhalt, Germany.

OBJECTIVES: Treatment with lipid-lowering therapy (LLT) such as statins, cholesterol absorption inhibitors, or PCSK9 inhibitors is of major importance for the survival of patients with atherosclerotic diseases, and adherence to LLT is essential for treatment success. The intention of this study was to investigate adherence to LLT in patients with coronary heart disease (CHD) in a 12-month follow-up period in Saxony-Anhalt, the state with the highest incidence and mortality for CHD in Germany. PATIENTS AND METHODS: Data were taken from 542 hospitalized patients with angiographically documented CHD who were prospectively included in this study conducted in the Department of Medicine III of the University Clinics (Halle). We collected data concerning medication at discharge and after 3 and 12 months. RESULTS: A total of 542 patients were included in this study. Mean age was 69.2 ± 11.8 years. In all, 68.8% were males, 165 (30.4%) were smokers, 39.7% suffered from diabetes, and 86.9% had arterial hypertension. The follow-up time of this study was 12 months. At discharge, 463 patients (85.4%) were being treated with a statin. After 3 months 409 (75.5%) and after 12 months, 395 patients (72.9%) were still on statin therapy, respectively. In total treatment, adherence for the statin medication decreased by 15.7% in 12 months. Kaplan-Meier analyses showed that survival, taken as freedom of death from any cause, decreased significantly if statin treatment was stopped (p=0.001). This was confirmed by multivariate Cox regression (HR 1.78, p=0.012). Ezetemibe was prescribed for 56 patients at discharge (10.3%). After 3 months, 40 patients (7.4%) were still taking ezetemibe. After 12 months, adherence to ezetemibe treatment decreased to 4.1% (22 patients). CONCLUSION: During follow-up for 3 and 12 months, adherence for statin therapy decreased by 15.7% and for ezetemibe by 46.6%. Here, low adherence to statin therapy was associated with fatal outcome.

Prognosis of patients with pulmonary embolism after rehabilitation.

INTRODUCTION: Pulmonary embolism (PE) is a life-threatening disease; in Germany, therefore, rehabilitation after PE is recommended in patients with intermediate- and high-risk PE. However, no prospective data on PE after inpatient rehabilitation have been published so far. PATIENTS AND METHODS: For this monocentric study, 70 patients with PE were prospectively recruited between November 2013 and November 2014 after giving written informed consent. This study was approved by the ethics committee of the Medical Association of Saxony-Anhalt. Inclusion criteria were as follows: age ≥18 years and a stay at the Paracelsus-Harz Clinic in Bad Suderode, Germany, with the main indication of PE. During the hospital stay, history-relevant medical data and diagnostic findings were collected and documented. Furthermore, we recorded whether patients were rehospitalized or died during the treatment period in the rehabilitation clinic or during the 12-month follow-up. RESULTS: The mean age was 64.5 ± 13.0 years, the mean body mass index (BMI) was 30.4 ± 6.0 kg/m2, and 54.3% were women. During rehabilitation, two patients (3.9%) were transferred to a primary care hospital; no patient died. However, four patients died (5.7%) in the 12-month follow-up period. A total of 20 patients were hospitalized in the 12-month follow-up period (hospitalization rate during the 12-month follow-up period: 28.6%). Of these 20 patients, one patient was rehospitalized with a newly diagnosed PE (1.4%) and two patients were rehospitalized for bleeding events (2.8%). CONCLUSION: PE is a life-threatening disease, and therefore it seems reasonable to recommend rehabilitation at least in patients with an intermediate- or high-risk PE. In this study, death and other serious event rates were low during the in-hospital rehabilitation and in the 12-month follow-up period, which underlined the safety and importance of a standardized rehabilitation program after survived PE.

Imaging Mass Spectrometry for Characterization of Atrial Fibrillation Subtypes.

PURPOSE: Atrial fibrillation (AF) is a cardiac arrhythmia characterized by a rapid and irregular heart rhythm. AF types, paroxysmal (PX), persistent (PE), and long-lasting persistent (LSP), require differences in clinical management. Unfortunately, a significant proportion of AF patients are clinically misclassified. Therefore, the aim of this study is to prove that MALDI-Imaging (IMS) is valuable as a diagnostic aid in AF subtypes' assessment. EXPERIMENTAL DESIGN: Patients are clinically classified according to the guidelines of the European Society of Cardiology. FFPE tissue specimens from PE, PX, and LSP subtypes are analyzed by MALDI-IMS and evaluated by multi-statistical testing. Proteins are subsequently identified using LC-MS/MS and findings are confirmed by immunohistochemistry and through the determination of potential fibrosis via histopathology. RESULT: Determined that characteristic peptide signatures and peptide values facilitate to distinguish between PE, PX, and LSP arterial fibrillation subtypes. In particular, peptide values from alpha 1 type I collagen (CO1A1) are identified that are significantly higher in LSP and PE tissues but not in PX myocardial AF tissue. These findings are confirmed by immunohistochemistry and through the determination of potential fibrosis via histopathology. CONCLUSION AND RELEVANCE: These results represent an improvement in AF risk stratification by using MALDI-IMS as a promising approach for AF tissue assessment.

Relationship between the Handball-Specific Complex-Test and Intermittent Field Test performance in professional players.

BACKGROUND: We investigated the relationship between the Handball Complex-Test (HBCT) and two selected field performance tests (the repeated sprint ability [RSA], and the Yo-Yo Intermittent Recovery Test) in elite handball players. METHODS: Nineteen handball players (age: 25.7±5.1 years) were drawn from the First Professional German League. The HBCT consists of four activity series (AS): agility parcours, defensive action, sprint (10 m, 20 m) and throw-on-goal parcours; these activities were completed twice, with five active pauses of 30-35 s, and a follow-up of recovery over the subsequent 10 minutes. The RSA comprised 6 x (15+15 m) sprints starting every 20 s; scoring noted best time (RSAbest), total time (RSATT) and decrement (RSAdec). In the Yo-Yo Intermittent Recover, we recorded the total distance covered (TD). Heart rates (HR) were recorded throughout and recovery was assessed for measurements immediately post-test (R0) and 10 minutes after completing the test (R10). RESULTS: A strong correlation was found between HBCT and fastest 10 m and 20 m RSA sprint times (r=0.811, r=0.815, respectively). Also, the HBCT total 10 m and 20 m sprint times showed a strong positive association with RSATT (r=0.70; r=0.63, respectively), and the RSA heart rate post-test was strongly correlated with the HBCT heart rate after round two (r=0.865). CONCLUSIONS: Data from the match-specific HBCT Test shows a strong positive association with other more generic intermittent field test measurements. These observations support the validity of using the generic tests to monitor current fitness and responses to training in team handball players.

Anthropometric and physical performance characteristics of professional handball players: influence of playing position.

BACKGROUND: The aims of the study were to examine the anthropometric and physical performance characteristics of professional handball players classified by playing position. METHODS: Twenty-one competitors (age: 25.2±5.1 years) were categorized as backs, pivots, wings or goalkeepers. Measures included anthropometrics (body height and mass), scores on the Yo-Yo Intermittent Recovery Test (total distance covered, TD), repeated-sprint ability (6 repetitions of 2x15-m shuttle sprints with recording of best time for a single trial, RSAbest) and performance on a complex handball test (HBKT) of throw slap (TS) and throw jump (TJ) with and without precision. RESULTS: The anthropometric data revealed a significantly lower body height for wings and pivots than for goalkeepers. Wings, pivots and goalkeepers were significantly shorter than backs, but had a similar BMI. The TD was greater for the wings (2.400 m) than for backs (1.832 m) and pivots (2.067m). Wings also achieved a better RSAbest (5.41 s) than backs (5.68 s) or pivots (5.82 s). Body height was significantly related to throw slap (TS) and jump (JT) (r=0.53, P<0.01; r=0.51, P<0.01 respectively). No significant difference (P=0.675; η2=0.009) was seen between JT with precision and JT without precision. CONCLUSIONS: Substantial differences of body build and physical performance between playing positions underline the importance of a careful assignment of such positions and the development of position-specific training for professional handball players by modifying both intermittent aerobic and anaerobic endurance components of training sessions.

Generation of coherent radiation in the vacuum ultraviolet using randomly quasi-phase-matched strontium tetraborate.

Tunable coherent radiation is generated in the vacuum ultraviolet down to 121 nm using random quasi-phase matching in strontium tetraborate, the shortest wavelength ever produced with a second-order nonlinear optical process in a solid-state material. Relevant properties of this radiation, the nonlinear process, and the nonlinear crystal are investigated.

Rehabilitation in Patients With Coronary Heart Disease: Participation and Its Effect on Prognosis.

BACKGROUND: In Germany, rehabilitation is considered to be indicated after an acute hospital stay for the treatment of a severe cardiac condition. In comparative studies, at least 51% of German hospital patients with coronary heart disease (CHD) who were entitled to rehabilitative measures actually took part n rehabilitation. METHODS: We examined data on 1910 patients with CHD who took part in two prospective cohort studies at the University Hospital of Halle (Saale) in the years 2007-2011. We contacted these patients again with a questionnaire to determine which ones had undergone rehabilitation. For patients who died before we could contact them, the attempt was made to obtain the dates and causes of death from the local authorities. The primary endpoint of was overall mortality. RESULTS: The median duration of follow-up was 136 ± 71 weeks. 727 patients (38.1%) had applied for rehabilitation during their acute hospitalization, but only 552 patients (28.9%) actually underwent it. Patients who did not undergo rehabilitation were older than those who did (68.6 ± 10.3 vs. 64.9 ± 10.5 years) and suffered more commonly from diabetes (41.3% vs. 33.7%; p = 0.002), arterial hypertension (89.2% vs. 85.3%; p = 0.017), and peripheral arterial occlusive disease (15.3% vs. 9.8%; p = 0.002). There were more smokers in the rehabilitation group. Kaplan-Meier analysis and multivariate Cox regression analysis both showed that the patients who underwent rehabilitation had lower mortality (hazard ratio 0.067, 95% confidence interval 0.025-0.180, p < 0.001). CONCLUSION: Rehabilitation for cardiac patients was associated with lower mortality. Fewer patients underwent rehabilitation in this study than in other, comparable studies. Those who did not were older and had a greater burden of accompanying disease.

Feasibility and safety of rehabilitation after venous thromboembolism.

BACKGROUND: Venous thromboembolism is a life-threatening disease. In survivors, different degrees of functional complaints need to be restored or prevented (eg, post-thrombotic syndrome, pulmonary hypertension). Therefore, rehabilitation after venous thromboembolism is recommended in Germany. However, a structured rehabilitation program has not been defined for this indication. Here, we present the experience of a single rehabilitation center. METHODS: Data from consecutive pulmonary embolism (PE) patients who were referred for a 3-week inpatient rehabilitation program from 2006 to 2014 were retrospectively evaluated. RESULTS: In all, 422 patients were identified. The mean age was 63.9±13.5 years, the mean body mass index (BMI) was 30.6±6.2 kg/m2, and 51.9% were female. Deep vein thrombosis according to PE was known for 55.5% of all patients. We applied a wide range of therapeutic interventions such as bicycle training with monitored heart rate in 86.7%, respiratory training in 82.5%, aquatic therapy/swimming in 40.1%, and medical training therapy in 14.9% of all patients. Adverse events (AEs) occurred in 57 patients during the 3-week rehabilitation period. The most common AEs were cold (n=6), diarrhea (n=5), and infection of the upper or lower respiratory tract that was treated with antibiotics (n=5). However, three patients under anticoagulation therapy suffered from bleeding, which was clinically relevant in one. Four patients (0.9%) had to be transferred to a primary care hospital for non-PE-associated reasons (acute coronary syndrome, pharyngeal abscess, and acute abdominal problems). No influence of any of the physical activity interventions on the incidence of any AE was found. CONCLUSION: Since PE is a life-threatening disease, it seems reasonable to recommend rehabilitation at least in PE patients with an intermediate or high risk. It is shown for the first time in this study that a standard rehabilitation program after PE is safe. However, efficacy and safety in the long term need to be studied prospectively.

Spectral fringes in non-phase-matched SHG and refinement of dispersion relations in the VUV.

We consider second harmonic generation (SHG) of ultrashort pulses in the case of strong phase- and group-velocity mismatch. Spectral fringes appear in the second harmonic related to two delayed replicas of the fundamental pulse in the time domain. The fringe separation can be used to evaluate the group-velocity and refractive index of nonlinear crystals at extreme wavelengths. Experimental results with femtosecond pulses in SrB(4)O(7) (SBO) are used to refine the Sellmeier equation describing the n(c) refractive index down to 160 nm, essential for the use of this unique nonlinear crystal for random quasi-phase-matching in the VUV.

Men and women differ in their diurnal expression of monocyte peroxisome proliferator-activated receptor-α in the fed but not in the fasted state.

Peroxisome proliferator-activated receptor-α (PPARα) plays a pivotal role in regulating metabolic response to fasting and is an inhibitor of inflammatory pathways in immune cells. It represents a therapeutic target for treatment of several diseases, mainly hyperlipidemia. To shed light on PPARα expression changes in response to fasting, young healthy male and female volunteers were fed or fasted for 24 hours. Monocytes were analyzed every 2 hours to compile both profiles of mRNA and protein expression of PPARα and its interactive partner, the circadian pacemaker brain and muscle aryl hydrocarbon receptor nuclear translocator like-1 (BMAL1). We found that women change their diurnal expression profiles of PPARα and BMAL1 when switching from the fed to the fasted state, whereas men do not. Interestingly, the PPARα and BMAL1 profiles of men and women in the fed state are different, whereas the profiles in the fasted state are virtually identical. The finding of diametrically opposite responses of male and female PPARα expression in the fed state might have practical implication in human medicine as PPARα activators like fibrates are used for the therapy of chronic lymphocytic leukemia, microvascular complications in diabetes, and kidney diseases.

High-average-power, 50-fs parametric amplifier front-end at 1.55 µm.

An average-power-scalable, two-stage optical parametric chirped pulse amplifier is presented providing 90-µJ signal pulses at 1.55 µm and 45-µJ idler pulses at 3.1 µm at a repetition rate of 100 kHz. The signal pulses were recompressible to within a few percent of their ~50-fs Fourier limit in anti-reflection coated fused silica at negligible losses. The overall energy conversion efficiency from the 1030-nm pump to the recompressed signal reached 19%, significantly reducing the cost per watt of pump power compared to similar systems. The two-stage source will serve as the front-end of a three-stage system permitting the development of novel experimental strategies towards laser-based imaging of molecular structures and chemical reactivity.

Evaluation of the prognostic role of tumor cell podoplanin expression in locally advanced squamous cell carcinoma of the head and neck.

BACKGROUND AND PURPOSE: To investigate the potential prognostic role of tumor cell podoplanin expression in patients treated with resection followed by irradiation or chemoradiotherapy for locally advanced squamous cell carcinoma of the head and neck (SCCHN). MATERIALS AND METHODS: Podoplanin expression (≤10 % versus > 10 %) and 12 other factors were evaluated in 160 patients for their association with locoregional control (LRC), metastases-free (MFS) and overall survival (OS). Other factors were age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, preradiotherapy (pre-RT) hemoglobin level, tumor site, histological grading, T category, N category, American Joint Committee on Cancer (AJCC) stage, human papillomavirus (HPV) status, extent of resection and concurrent chemotherapy. RESULTS: In multivariate analysis, ECOG performance status 0-1 (risk ratio, RR: 3.01; 95 % confidence interval, CI: 1.42-7.14; p = 0.003), pre-RT hemoglobin levels ≥ 7.45 mmol/l (12 g/dl; RR: 2.03; 95 % CI: 1.04-3.94; p = 0.038), oropharyngeal cancer (RR: 1.25; 95 % CI: 1.01-1.55; p = 0.038) and T category T1-2 (RR: 1.81; 95 % CI: 1.24-2.79; p = 0.002) were significantly associated with improved LRC. T category T1-2 (RR: 1.90; 95 % CI: 1.25-3.06; p = 0.002) and N category N0-2a (RR: 5.22; 95 % CI: 1.96-18.09; p < 0.001) were significantly associated with better MFS. Pre-RT hemoglobin levels ≥ 7.45 mmol/l (RR: 2.44; 95 % CI: 1.27-4.74; p = 0.007), T category T1-2 (RR: 1.97; 95 % CI: 1.36-3.04; p < 0.001) and N category N0-2a (RR: 2.87; 95 % CI: 1.37-6.61; p = 0.005) were significantly associated with improved OS. Podoplanin expression ≤ 10 % showed a trend towards improved OS on both univariate (p = 0.050) and multivariate analysis (RR: 1.86; 95 % CI: 0.96-3.59; p = 0.07). CONCLUSION: Treatment outcomes were significantly associated with performance status, pre-RT hemoglobin level, tumor site and tumor stage. Tumor cell expression of podoplanin ≤ 10 % showed a trend towards improved OS when compared to podoplanin expression of > 10 %.

Generation of tunable sub-45 femtosecond pulses by noncollinear four-wave mixing.

Generation of sub-45 fs vacuum UV (VUV) pulses tunable across the spectral range of 146-151 nm at 1 kHz repetition rate is reported. The pulses are produced using noncollinear difference-frequency four-wave mixing between the third-harmonic of an amplified Ti:sapphire laser and the signal wavelength of an infrared optical parametric amplifier (ω(VUV)=2ω(TH)-ω(IR)) in krypton and argon. The generated VUV pulses have energies as high as 90 nJ. Pulse duration measurements are realized by cross correlation between the VUV pulses and the laser fundamental wavelength using pump-probe ionization in xenon.

Elevation of matrix metalloproteinases in different areas of ascending aortic aneurysms in patients with bicuspid and tricuspid aortic valves.

Our aim is to investigate the elevation of matrix proteins in tissues obtained from distal, above the sinotubular junction (proximal), concave, and convex sites of aneurysms in the ascending aorta using a simultaneous multiplex protein detection system. Tissues were collected from 41 patients with ascending aortic aneurysms. A total of 31 patients had a bicuspid aortic valve (BAV), whereas 10 had a tricuspid aortic valve (TAV). Concave and convex aortic site samples were collected from all patients, whereas proximal and distal convexity samples were obtained from 19 patients with BAV and 7 patients with TAV. Simultaneous detection of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) was performed at each of the four aortic sites. MMP-2 levels were higher in the concave aortic sites than in the convex aortic sites. In contrast, MMP-8 levels were higher in the convex sites than in the concave sites, as were MMP-9 levels. In both BAV and TAV patients, TIMP-3 levels were higher in the concave sites than in the convex sites. However, TIMP-2 and TIMP-4 levels were significantly elevated in the sinotubular proximal aorta of BAV patients. Simultaneous detection of MMPs and TIMPs revealed different levels at different aortic sites in the same patient.

Laryngeal chondrosarcoma with unusual dissemination to the humerus.

We report the case of an 81-year-old woman admitted to our clinic with a 16-month history of hoarseness due to unilateral vocal cord immobilization, slowly progressive dysphagia and an episode of painless swelling of the right arm. Radiological and histological workup revealed a medium-grade conventional chondrosarcoma of the cricoid cartilage with paratracheal spread and dissemination to the lung and the humeral bone. To our knowledge, this is the first humeral bone metastasis of laryngeal chondrosarcoma reported in the literature. The course of the presented case underlines the need for an early and detailed clinical and radiological workup of vocal cord immobilization.

Pathological complete remission in patients with oesophagogastric cancer receiving preoperative 5-fluorouracil, oxaliplatin and docetaxel.

The aim of this study was to determine the pathological complete remission (pCR) rate, and its relationship to clinical outcome, in patients with adenocarcinoma of the stomach or oesophagogastric junction receiving preoperative 5-fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) every 2 weeks. Data from these patients who received at least one cycle of preoperative FLOT followed by surgery were prospectively collected in three German centres. Outcome analyses were conducted and tumour samples were evaluated for pathological remission by a central pathologist. A total of 46 patients were included in this analysis. All patients had clinical T3- and/or N+-stages and 11 (23.9%) had distant metastases (M1). After a median of 4 (range 2-8) preoperative cycles, 8 of 46 patients (17.4%) achieved a pCR. The pCR rate was highest in tumours of intestinal type histology (30.8%) and in those located in the oesophagogastric junction (30.4%) and lowest in patients with diffuse/mixed type tumours (0%) or tumours located in the stomach (4.3%; p < 0.05 for both comparisons). Patients with pCR had 100% probability of overall and disease-free survival (DFS) during the observation period, which was significantly higher (p = 0.037 and p = 0.009, respectively) than the survival probability in patients without pCR. In conclusion, treatment intensification using FLOT was associated with significant pCR rates in patients with oesophagogastric cancer. The distribution of pCR appeared to be significantly different according to histological type and location of the tumours.

Fibroblast growth factor 2--a predictor of outcome for patients irradiated for stage II-III non-small-cell lung cancer.

PURPOSE: The prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients with non-small-cell lung cancer (NSCLC) is unclear. The present study investigated the effect of tumor cell expression of FGF-2 on the outcome of 60 patients irradiated for Stage II-III NSCLC. METHODS AND MATERIALS: The effect of FGF-2 expression and 13 additional factors on locoregional control (LRC), metastasis-free survival (MFS), and overall survival (OS) were retrospectively evaluated. These additional factors included age, gender, Karnofsky performance status, histologic type, histologic grade, T and N category, American Joint Committee on Cancer stage, surgery, chemotherapy, pack-years, smoking during radiotherapy, and hemoglobin during radiotherapy. Locoregional failure was identified by endoscopy or computed tomography. Univariate analyses were performed with the Kaplan-Meier method and the Wilcoxon test and multivariate analyses with the Cox proportional hazard model. RESULTS: On univariate analysis, improved LRC was associated with surgery (p = .017), greater hemoglobin levels (p = .036), and FGF-2 negativity (p <.001). On multivariate analysis of LRC, surgery (relative risk [RR], 2.44; p = .037), and FGF-2 expression (RR, 5.06; p <.001) maintained significance. On univariate analysis, improved MFS was associated with squamous cell carcinoma (p = .020), greater hemoglobin levels (p = .007), and FGF-2 negativity (p = .001). On multivariate analysis of MFS, the hemoglobin levels (RR, 2.65; p = .019) and FGF-2 expression (RR, 3.05; p = .004) were significant. On univariate analysis, improved OS was associated with a lower N category (p = .048), greater hemoglobin levels (p <.001), and FGF-2 negativity (p <.001). On multivariate analysis of OS, greater hemoglobin levels (RR, 4.62; p = .002) and FGF-2 expression (RR, 3.25; p = .002) maintained significance. CONCLUSIONS: Tumor cell expression of FGF-2 appeared to be an independent negative predictor of LRC, MFS, and OS.
