Abstract
Respiratory viral infections may have different impacts ranging from infection without symptoms to severe disease or even death though the reasons are not well characterized. A patient (age group 5-15 years) displaying symptoms of hemolytic uremic syndrome died one day after hospitalization. qPCR, next generation sequencing, virus isolation, antigenic characterization, resistance analysis was performed and virus replication kinetics in well-differentiated airway cells were determined. Autopsy revealed hemorrhagic pneumonia as major pathological manifestation. Lung samples harbored a large population of A(H1N1)pdm09 viruses with the polymorphism H456H/Y in PB1 polymerase. The H456H/Y viruses replicated much faster to high viral titers than upper respiratory tract viruses in vitro. H456H/Y-infected air-liquid interface cultures of differentiated airway epithelial cells did reflect a more pronounced loss of ciliated cells. A different pattern of virus quasispecies was found in the upper airway samples where substitution S263S/F (HA1) was observed. The data support the notion that viral quasispecies had evolved locally in the lung to support high replicative fitness. This change may have initiated further pathogenic processes leading to rapid dissemination of inflammatory mediators followed by development of hemorrhagic lung lesions and fatal outcome.

Abstract
PURPOSE To investigate the role of Dkk1 as a predictor of response to NACT in BC patients. METHODS This retrospective monocentric study included 145 women who had undergone NACT followed by breast surgery. Dkk1 protein expression was assessed using immunohistochemistry staining in core needle biopsies and mammary carcinoma specimens. RESULTS Dkk1 levels were lower in treated BC tumours than in untreated tumours. The outcomes of 68 matched pre- and post-therapy tissues showed that Dkk1 levels in mammary carcinoma tissues were significantly predicted by levels in core needle biopsies and that Dkk1 expression was reduced in 83% of cases. Smaller cT stage, positive Her2 expression, and decreased Dkk1-IRS in core needle biopsy tissues were all independent predictors of regression grade (R4), according to Sinn. However, the percentage of Dkk1 expression differences prior to and following NACT had no effect on PFS or OS. CONCLUSIONS In this study, we demonstrated for the first time that Dkk1 could be identified as an independent predictor of NACT response in BC patients, particularly those with TNBC. Further research with a multicentric expanded (pre-/post-therapy) sample set and better-defined populations in terms of molecular subtypes, therapy modality, and long-term follow-up is recommended to obtain more solid evidence.

Abstract
BACKGROUND Advanced penile carcinoma is characterized by poor prognosis. Most data on prognostic factors are based on small study cohorts, and even meta-analyses are limited in patient numbers. Therefore, there is still a lack of evidence for clinical decisions. In addition, the most recent TNM classification is questionable; in line with previous studies, we found that it has not improved prognosis estimation. METHODS We evaluated 297 patients from Germany, Russia, and Portugal. Tissue samples from 233 patients were re-analyzed by two experienced pathologists. HPV status, p16, and histopathological parameters were evaluated for all patients. RESULTS Advanced lymph node metastases (N2, N3) were highly significantly associated with reductions in metastasis-free (MFS), cancer-specific (CS), and overall survival (OS) rates (p = <0.001), while lymphovascular invasion was a significant parameter for reduced CS and OS (p = 0.005; p = 0.007). Concerning the primary tumor stage, a significant difference in MFS was found only between pT1b and pT1a (p = 0.017), whereas CS and OS did not significantly differ between T categories. In patients without lymph node metastasis at the time of primary diagnosis, lymphovascular invasion was a significant prognostic parameter for lower MFS (p = 0.032). Histological subtypes differed in prognosis, with the worst outcome in basaloid carcinomas, but without statistical significance. HPV status was not associated with prognosis, either in the total cohort or in the usual type alone. CONCLUSION Lymphatic involvement has the highest impact on prognosis in penile cancer, whereas HPV status alone is not suitable as a prognostic parameter. The pT1b stage, which includes grading, as well as lymphovascular and perineural invasion in the T stage, seems questionable; a revision of the TNM classification is therefore required.

Abstract
Background Due to the expanding role of immune checkpoint inhibition in the treatment of head and neck squamous cell carcinoma, understanding immunological processes in the tumor microevironment (TME) has strong translational importance. Though analytical methods for a comprehensive analysis of the immunological TME have constantly improved and expanded over the past years the prognostic relevance of immune cell composition in head and neck cancer TME largely remains ambiguous with most studies focusing on one or a small subset of immune cells. Methods The overall survival (OS) of the TCGA-HNSC patient cohort comprising 513 head and neck cancer patients was correlated with a total of 29 different immune metrics including a wide spectrum of immune cell subpopulations as well as immune checkpoint receptors and cytokines using RNAseq based immune deconvolution analyses. The most significant predictors of survival among these 29 immune metrics were validated on a separate HNSCC patient cohort (n=101) using immunohistochemistry: CD3, CD20+CXCR5, CD4+CXCR5, Foxp3 and CD68. Results Overall immune infiltration irrespective of immune cell composition showed no significant correlation with the patients' overall survival in the TCGA-HNSC cohort. However, when focusing on different immune cell subpopulations, naïve B cells (p=0.0006), follicular T-helper cells (p<0.0001), macrophages (p=0.0042), regulatory T cells (p=0.0306), lymphocytes (p=0.0001), and cytotoxic T cells (p=0.0242) were identified as highly significant predictors of improved patient survival. Using immunohistochemical detection of these immune cells in a second independent validation cohort of 101 HNSCC patients, we confirmed the prognostic relevance of follicular T helper cells, cytotoxic T cells and lymphocytes. In multivariable analysis, HPV negativity and advanced UICC stages were identified as additional prognostic biomarkers associated with poor outcome. Conclusion Our study highlights the prognostic relevance of the immunological tumor environment in head and neck cancer and demonstrates that a more detailed analysis of immune cell composition and immune cell subtypes is necessary to accurately prognosticate. We observed the highest prognostic relevance for lymphocytes, cytotoxic T cells, and follicular T helper cells, suggesting further investigations focusing on these specific immune cell subpopulations not only as predictors of patient prognosis but also as promising targets of new immunotherapeutic strategies.

Abstract
In the absence of targeted treatment options, neoadjuvant chemotherapy (NACT) is applied widely for triple-negative breast cancer (TNBC). Response to NACT is an important parameter predictive of oncological outcomes (progression-free and overall survival). An approach to the evaluation of predictive markers enabling therapy individualization is the identification of tumor driver genetic mutations. This study was conducted to investigate the role of SEC62, harbored at 3q26 and identified as a driver of breast cancer pathogenesis, in TNBC. We analyzed SEC62 expression in The Cancer Genome Atlas database, and immunohistologically investigated SEC62 expression in pre- and post-NACT tissue samples from 64 patients with TNBC treated at the Department of Gynecology and Obstetrics/Saarland University Hospital/Homburg between January 2010 and December 2018 and compared the effect of SEC62 on tumor cell migration and proliferation in functional assays. SEC62 expression dynamics correlated positively with the response to NACT (p ≤ 0.01) and oncological outcomes (p ≤ 0.01). SEC62 expression stimulated tumor cell migration (p ≤ 0.01). The study findings indicate that SEC62 is overexpressed in TNBC and serves as a predictive marker for the response to NACT, a prognostic marker for oncological outcomes, and a migration-stimulating oncogene in TNBC.

Abstract
BACKGROUND AND OBJECTIVE The incidence of basal cell carcinoma (BCC) has significantly increased in the last decades. The aim of this retrospective study was to determine the risk of recurrence of periocular BCC after histologically controlled resection. PATIENTS AND METHODS Based on the clinical records from 2009-2020 a total of 270 consecutive periocular BCCs from 243 patients were investigated with respect to recurrence after surgical excision. For this study, the type of BCC (primary or recurrent BCC) and localization within the orbital region (upper eyelid nasal, middle, temporal and lower eyelid nasal, middle, temporal) and the histological BCC subtype, e.g. solid/nodular (s/n), superficial multicentric (s-m), infiltrative/sclerodermal (i/s), basosquamous (bsq) and mixed (gem), were recorded. Recurrence rates were compared using χ2-tests. RESULTS The 270 resected BCCs with 231 primary BCC (pBCC) and 39 already recurrent BCC (rBCC), were included in this study. Among the 231 pBCCs we recorded a total of 38 (16.5%, 2‑year recurrence rate 9.2%) recurrences for the abovementioned period. In the 39 rBCCs we observed 18 (46.2%) recurrences (2-year recurrence rate 37.8%). In addition, a significantly shorter recurrence-free interval (RFV, ∅ 52.6 ± 9.0 months) was observed for the rBCC than for the pBCC (∅108.6 ± 4.1 months, p < 0.001). The recurrence rates did not differ significantly with respect to the location; however, there was a significant difference between the five defined subtypes (p = 0.001): s/n = 15.9%, s‑m = 45.0%, i/s = 27.8%, bsq = 33.3% and gem = 40.0%. After R0 resection the recurrence rate of s/n BCC was significantly lower than after R?/R1 resection (p = 0.008). The histological subtypes i/s (p = 0.433), bsq (p = 0.417), and gem (p = 0.143), showed no significant difference between the recurrence rates after R0 and R?/R1 resection. In s‑m BCC, a conclusion on the statistical significance was not possible. DISCUSSION The recurrence rate appears to be comparatively high; however, R1 resected BCCs were intentionally included in this study to obtain an evaluation that reflects clinical practice as realistically as possible. It is possible that the surgical procedure and/or the type of histological examination as well as the broad interpretation of the term local recurrence could be the reason for the different recurrence data in the literature. Our data indicate that the recurrence rate is not affected by the exact localization within the orbital region, but by the respective BCC subtype. As recurrences may develop years after BCC excision a long-term follow-up is strictly recommended.

Abstract
The tumor microenvironment stimulates the angiogenic activity of endothelial cells (ECs) to facilitate tumor vascularization, growth, and metastasis. The involvement of microRNA-186-5p (miR-186) in regulating the aberrant activity of tumor-associated ECs has so far not been clarified. In the present study, we demonstrated that miR-186 is significantly downregulated in ECs microdissected from human non-small cell lung cancer (NSCLC) tissues compared with matched non-malignant lung tissues. In vitro analyses of primary human dermal microvascular ECs (HDMECs) exposed to different stimuli indicated that this miR-186 downregulation is triggered by hypoxia via activation of hypoxia-inducible factor 1 alpha (HIF1α). Transfection of HDMECs with miR-186 mimic (miR-186m) significantly inhibited their proliferation, migration, tube formation, and spheroid sprouting. In contrast, miR-186 inhibitor (miR-186i) exerted pro-angiogenic effects. In vivo, endothelial miR-186 overexpression inhibited the vascularization of Matrigel plugs and the initial growth of tumors composed of NSCLC cells (NCI-H460) and HDMECs. Mechanistic analyses revealed that the gene encoding for protein kinase C alpha (PKCα) is a bona fide target of miR-186. Activation of this kinase significantly reversed the miR-186m-repressed angiogenic activity of HDMECs. These findings indicate that downregulation of miR-186 in ECs mediates hypoxia-stimulated NSCLC angiogenesis by upregulating PKCα.

Abstract
With approximately 220,000 newly diagnosed cases per year, ovarian cancer is among the most frequently occurring cancers among women and the second leading cause of death from gynecological malignancies worldwide. About 70% of these cancers are diagnosed in advanced stages (FIGO IIB-IV), with a 5-year survival rate of 20-30%. Due to the poor prognosis of this disease, research has focused on its pathogenesis and the identification of prognostic factors. One possible approach for the identification of biological markers is the identification of tumor entity-specific genetic "driver mutations". One such mutation is 3q26 amplification in the tumor driver SEC62, which has been identified as relevant to the pathogenesis of ovarian cancer. This study was conducted to investigate the role of SEC62 in ovarian malignancies. Patients with ovarian neoplasias (borderline tumors of the ovary and ovarian cancer) who were treated between January 2007 and April 2019 at the Department of Gynecology and Obstetrics, Saarland University Hospital, were included in this retrospective study. SEC62 expression in tumor tissue samples taken during clinical treatment was assessed immunohistochemically, with the calculation of immunoreactivity scores according to Remmele and Stegner, Pathologe, 1987, 8, 138-140. Correlations of SEC62 expression with the TNM stage, histological subtype, tumor entity, and oncological outcomes (progression-free and overall survival) were examined. The sample comprised 167 patients (123 with ovarian cancer and 44 with borderline tumors of the ovary) with a median age of 60 (range, 15-87) years. At the time of diagnosis, 77 (46%) cases were FIGO stage III. All tissue slides showed SEC62 overexpression in tumor cells and no SEC62 expression in other cells. Median immunoreactivity scores were 8 (range, 2-12) for ovarian cancer and 9 (range, 4-12) for borderline tumors of the ovary. Patients with borderline tumors of the ovary as well as patients with ovarian cancer and an immunoreactive score (IRS) ≤ 9 showed an improved overall survival compared to those presenting with an IRS score >9 (p = 0.03). SEC62 seems to be a prognostic biomarker for the overall survival of patients with ovarian malignancies.

Abstract
In this Letter to the Editor supportive data were presented to a recent paper published in this journal reporting the involvement of TRP channels in COVID-19 pneumonia and its role for new therapies. Since gene expression of TRP channels was found in human lung tissues the protein was not being reported so far. TRP channels are supposed to be involved in the pulmonary inflammation and its symptoms such as fever, cough and others. Here, TRPC6 was investigated in tissues of normal human lungs and of SARS-Cov-2 infected lungs in a preliminary study. Tissue was obtained post mortem from anatomical body donations during dissections and during pathological dissections (13 normal, 4 COVID-19 pneumoniae) and processed for immunohistochemistry. In normal lungs TRPC6 was found in the ciliated epithelium, in the wall of larger lung vessels and in the alveolar septa. In COVID-19 pneumonia the distribution of TRPC6 was different. Inflammatory lesions, cellular infiltrates, hyaline membranes and fibrosis were labelled intensively as well as dilated capillaries. These observations are from four patients with COVID-19 pneumonia.The observations do not elucidate the molecular mechanisms but support the view that TRPC6 channels are involved in normal physiology of normal human lungs and in COVID-19 pneumonia. TRPC6 might aggravate SARS-2 induced inflammation and could be a target for inhibiting drugs.

Abstract
The use of autopsies in medicine has been declining. The COVID-19 pandemic has documented and rejuvenated the importance of autopsies as a tool of modern medicine. In this review, we discuss the various autopsy techniques, the applicability of modern analytical methods to understand the pathophysiology of COVID-19, the major pathological organ findings, limitations or current studies, and open questions. This article summarizes published literature and the consented experience of the nationwide network of clinical, neuro-, and forensic pathologists from 27 German autopsy centers with more than 1200 COVID-19 autopsies. The autopsy tissues revealed that SARS-CoV-2 can be found in virtually all human organs and tissues, and the majority of cells. Autopsies have revealed the organ and tissue tropism of SARS-CoV-2, and the morphological features of COVID-19. This is characterized by diffuse alveolar damage, combined with angiocentric disease, which in turn is characterized by endothelial dysfunction, vascular inflammation, (micro-) thrombosis, vasoconstriction, and intussusceptive angiogenesis. These findings explained the increased pulmonary resistance in COVID-19 and supported the recommendations for antithrombotic treatment in COVID-19. In contrast, in extra-respiratory organs, pathological changes are often nonspecific and unclear to which extent these changes are due to direct infection vs. indirect/secondary mechanisms of organ injury, or a combination thereof. Ongoing research using autopsies aims at answering questions on disease mechanisms, e.g., focusing on variants of concern, and future challenges, such as post-COVID conditions. Autopsies are an invaluable tool in medicine and national and international interdisciplinary collaborative autopsy-based research initiatives are essential.

Abstract
OBJECTIVES The aim of this study was to compare the diagnostic accuracy of apparent diffusion coefficient (ADC) ratios as a monoparametric magnetic resonance imaging (MRI) protocol for the detection of prostate cancer (PCa) with the established multiparametric (mp) MRI at 3.0 T. MATERIALS AND METHODS According to power analysis, 52 male patients were included in this monocenter study with prospective data collection and retrospective, blinded multireader image analysis. The study was approved by the local ethics committee. Patients were recruited from January to December 2020. Based on mpMRI findings, patients underwent in-bore MR biopsy or prostatectomy for histopathologic correlation of suspicious lesions. Three readers, blinded to the histopathologic results and images of mpMRI, independently evaluated ADC maps for the detection of PCa. The ADC ratio was defined as the lowest signal intensity (SI) of lesions divided by the SI of normal tissue in the zone of origin. Predictive accuracy of multiparametric and monoparametric MRI were compared using logistic regression analysis. Moreover, both protocols were compared applying goodness-of-fit analysis with the Hosmer-Lemeshow test for continuous ADC ratios and Pearson χ2 test for binary decision calls, correlation analysis with Spearman ρ and intraclass correlation coefficients, as well as noninferiority assessment with a TOST ("two one-sided test"). RESULTS Eighty-one histopathologically proven, unique PCa lesions (Gleason score [GS] ≥ 3 + 3) in 52 patients could be unequivocally correlated, with 57 clinically significant (cs) PCa lesions (GS ≥ 3 + 4). Multiparametric MRI detected 95%, and monoparametric ADC detected ratios 91% to 93% of csPCa. Noninferiority of monoparametric MRI was confirmed by TOST (P < 0.05 for all comparisons). Logistic regression analysis revealed comparable predictive diagnostic accuracy of ADC ratios (73.7%-87.8%) versus mpMRI (72.2%-84.7%). Spearman rank correlation coefficient for PCa aggressiveness revealed satisfactory correlation of ADC ratios (P < 0.013 for all correlations). The Hosmer-Lemeshow test for the logistic regression analysis for continuous ADC ratios indicated adequate predictive accuracy (P = 0.55-0.87), and the Pearson χ2 test showed satisfactory goodness of fit (P = 0.35-0.69, χ2 = 0.16-0.87). CONCLUSIONS Normalized ADC ratios based on advanced DWI are noninferior to mpMRI at 3.0 T for the detection of csPCa in a preselected patient cohort and proved a fast and accurate assessment tool, thus showing a potential prospect of easing the development of future screening methods for PCa.

Abstract
MicroRNAs (miRNAs) expressed in endothelial cells (ECs) are powerful regulators of angiogenesis, which is essential for tumor growth and metastasis. Here, we demonstrated that miR-22 is preferentially and highly expressed in ECs, while its endothelial level is significantly downregulated in human non-small cell lung cancer (NSCLC) tissues when compared to matched nontumor lung tissues. This reduction of endothelial miR-22 is possibly induced by NSCLC cell-secreted interleukin-1β and subsequently activated transcription factor nuclear factor-κB. Endothelial miR-22 functions as a potent angiogenesis inhibitor that inhibits all of the key angiogenic activities of ECs and consequently NSCLC growth through directly targeting sirtuin 1 and fibroblast growth factor receptor 1 in ECs, leading to inactivation of AKT/mammalian target of rapamycin signaling. These findings provide insight into the molecular mechanisms of NSCLC angiogenesis and indicate that endothelial miR-22 represents a potential target for the future antiangiogenic treatment of NSCLC.

Abstract
Simple Summary Little is known about the motility and interaction of primary human lymphoma cells in lymph nodes. The aim of this study therefore was to analyze for the first time if there are differences in motility and interaction with bystander cells between different lymphoma types and normal lymph nodes. We observed systematic differences between B cells and PD1-positive T cells. Furthermore, most cases of Hodgkin lymphomas had fast moving PD1-positive T cells, whereas there was little movement in other lymphoma types. Some lymphomas, particularly Hodgkin lymphomas, presented enhanced cell contacts between neoplastic and reactive cells, suggesting a dependency of lymphoma growth on cellular interaction. Abstract Profound knowledge exists about the clinical, morphologic, genomic, and transcriptomic characteristics of most lymphoma entities. However, information is currently lacking on the dynamic behavior of malignant lymphomas. This pilot study aimed to gain insight into the motility of malignant lymphomas and bystander cells in 20 human lymph nodes. Generally, B cells were faster under reactive conditions compared with B cells in malignant lymphomas. In contrast, PD1-positive T cells did not show systematic differences in velocity between reactive and neoplastic conditions in general. However, lymphomas could be divided into two groups: one with fast PD1-positive T cells (e.g., Hodgkin lymphoma and mantle cell lymphoma; means 8.4 and 7.8 µm/min) and another with slower PD1-positive T cells (e.g., mediastinal grey zone lymphoma; mean 3.5 µm/min). Although the number of contacts between lymphoma cells and PD1-positive T cells was similar in different lymphoma types, important differences were observed in the duration of these contacts. Among the lymphomas with fast PD1-positive T cells, contacts were particularly short in mantle cell lymphoma (mean 54 s), whereas nodular lymphocyte-predominant Hodgkin lymphoma presented prolonged contact times (mean 6.1 min). Short contact times in mantle cell lymphoma were associated with the largest spatial displacement of PD1-positive cells (mean 12.3 µm). Although PD1-positive T cells in nodular lymphocyte-predominant Hodgkin lymphoma were fast, they remained in close contact with the lymphoma cells, in line with a dynamic immunological synapse. This pilot study shows for the first time systematic differences in the dynamic behavior of lymphoma and bystander cells between different lymphoma types.

Abstract
PURPOSE To report a case of simultaneous bilateral ophthalmic artery occlusion in diagnosed giant cell arteritis (GCA). OBSERVATIONS A 77-year-old male patient presented to the emergency department with simultaneous vision loss in both eyes for 3 hours. Headache at both temples and jaw claudication had been present for 3 weeks. Laboratory values demonstrated an initially increased C-reactive protein (CRP) of 202.0 mg/L and an erythrocyte sedimentation rate (ESR) of 100 mm within the first 20 minutes. Duplex sonography of the right and left temporal arteries revealed a "halo sign." A case of GCA was suspected, and intravenous high-dose methylprednisolone therapy was immediately administered. The clinical examination revealed a bilateral central retinal artery occlusion and fluorescein angiography showed a hot optic disc in the right eye and patchy choroidal hypoperfusion in both eyes. Biopsy of the left temporal artery was performed, which confirmed a florid temporal arteritis with complete thrombotic occlusion of the vascular lumen. Despite a good response to the administered therapy (CRP 17.0 mg/L 1 week after initiation), the visual prognosis was significantly limited through retinal and optic nerve involvement. By the follow-up examination 8 weeks later, the near visual acuity was 20/400 in the right and left eye at a distance of 16 inches. CONCLUSION AND IMPORTANCE We hereby present a simultaneous bilateral ophthalmic artery occlusion as a rare complication of GCA. The combination of central retinal artery occlusion, arteritic anterior ischemic optic neuropathy, and choroidal hypoperfusion suggests an acute inflammatory involvement of the ophthalmic artery. In cases of the slightest suspicion of giant cell arteritis, an immediate high-dose steroid therapy initiation is of utmost importance.

Abstract
CASE PRESENTATION A 71-year-old man was admitted to our hospital because of diffuse chest pain and a mass on routine chest radiography. He did not report cough, dyspnea, fever, night sweats, or weight loss. His medical history was remarkable for chronic lymphocytic leukemia diagnosed 13 years before presentation, and secondary myelodysplastic syndrome diagnosed 2 years before the onset of the current symptoms. As a curative approach, he had received a matched unrelated stem cell transplantation 16 months earlier, and he had been in complete remission since. He developed chronic graft-vs-host disease, presenting mainly as oral ulceration (grade 1, according to National Institute of Health consensus criteria), which had been treated with oral cyclosporine and extracorporeal photopheresis. The immunosuppression had been tapered 6 months before presentation. Routine medication included co-trimoxazole prophylaxis twice per week. He had no known allergies, and he denied recent travels and sick contacts.

Abstract
Chronic obstructive lung disease (COPD) and lung cancer are both caused by smoking and often occur as comorbidity. The programmed cell death protein 1/programmed cell death ligand 1 (PD-1/PD-L1) axis is an important canonic immunoregulatory pathway, and antibodies that specifically block PD-1 or PD-L1 have demonstrated efficacy as therapeutic agents for non-small cell lung cancer. The role of the PD-1/PD-L1 axis in the pathogenesis of COPD is unknown. Here, we analyzed the function of the PD-1/PD-L1 axis in preclinical COPD models and evaluated the concentrations of PD-1 and PD-L1 in human serum and bronchoalveolar lavage (BAL) fluids as biomarkers for COPD. Anti-PD-1 treatment decreased lung damage and neutrophilic inflammation in mice chronically exposed to cigarette smoke (CS) or nontypeable Haemophilus influenzae (NTHi). Ex vivo stimulated macrophages obtained from anti-PD-1-treated mice released reduced amounts of inflammatory cytokines. PD-L1 concentrations correlated positively with PD-1 concentrations in human serum and BAL fluids. Lung sections obtained from patients with COPD stained positive for PD-L1. Our data indicate that the PD-1/PD-L1 axis is involved in developing inflammation and tissue destruction in COPD. Inflammation-induced activation of the PD-1 pathway may contribute to disease progression.

Abstract
Although microRNAs are described as promising biomarkers in many tumor types, little is known about their role in PSCC. Thus, we attempted to identify miRNAs involved in tumor development and metastasis in distinct histological subtypes considering the impact of HPV infection. In a first step, microarray analyses were performed on RNA from formalin-fixed, paraffin-embedded tumor (22), and normal (8) tissue samples. Microarray data were validated for selected miRNAs by qRT-PCR on an enlarged cohort, including 27 tumor and 18 normal tissues. We found 876 significantly differentially expressed miRNAs (p ≤ 0.01) between HPV-positive and HPV-negative tumor samples by microarray analysis. Although no significant differences were detected between normal and tumor tissue in the whole cohort, specific expression patterns occurred in distinct histological subtypes, such as HPV-negative usual PSCC (95 differentially expressed miRNAs, p ≤ 0.05) and HPV-positive basaloid/warty subtypes (247 differentially expressed miRNAs, p ≤ 0.05). Selected miRNAs were confirmed by qRT-PCR. Furthermore, microarray data revealed 118 miRNAs (p ≤ 0.01) that were significantly differentially expressed in metastatic versus non-metastatic usual PSCC. The lower expression levels for miR-137 and miR-328-3p in metastatic usual PSCC were validated by qRT-PCR. The results of this study confirmed that specific miRNAs could serve as potential diagnostic and prognostic markers in single PSCC subtypes and are associated with HPV-dependent pathways.

Abstract
A 57-year-old Caucasian woman suffered from dyspnea on exertion. One year following a supposed pulmonary embolism event, a chronic thromboembolic vasculopathy was diagnosed and a pulmonary thromboendarterectomy was performed. However, a granulomatous pulmonary arterial vasculitis was identified upon examination. DNA of Mycobacterium goodii was detected as the most likely causative agent. Anti-inflammatory and anti-mycobacterial therapy was initiated for more than 12 months. Regular PET-CT scans revealed improvement under therapy. The last PET-CT did not show any tracer uptake following 10 months of therapy.

Abstract
BACKGROUND Seminomatous germ cell tumours (SGCT) are the most frequent malignancy in young men. Reliable prognostic biomarkers for the prediction of metastasis at diagnosis and the risk of relapse in clinical stage I (CSI) are lacking. Adjuvant therapies carry a risk of overtreatment, whereas salvage therapies have a risk of high toxicities. Thus, the identification of reliable prognostic biomarkers is highly desirable to identify patients who will benefit from early adjuvant treatment. MicroRNAs (miRNAs) regulate tumour development and progression, and their potential as biomarkers has already been proven in a variety of malignancies. OBJECTIVES The aim of our study was to define a specific miRNA expression pattern that discriminates metastatic from non-metastatic primary SGCT. MATERIALS AND METHODS Total RNA was isolated from 24 formalin-fixed paraffin-embedded (FFPE) primary SGCT tumours (10 non-metastatic, five metachronously and nine synchronously metastatic) and from 10 normal testicular tissue samples. Microarray analysis was performed for global miRNA expression profiling. The results were validated by quantitative real-time polymerase chain reaction (qRT-PCR). Statistical analysis was performed using SPSS. RESULTS Microarray analyses revealed a specific miRNA pattern that distinguishes metastatic from non-metastatic SGCT. Sixty-three miRNAs were differentially expressed in metastatic compared to non-metastatic tumours (P < .01). Microarray results were confirmed by qRT-PCR for three out of five selected miRNAs (miR-29c-5p, miR-506-3p and miR-371a-5p; P < .05). All five miRNAs (miR-29c-5p, miR-506-3p, miR-1307-5p, miR-371a-5p and miR-371a-3p) showed differential expression between tumour and normal tissues (P < .05). CONCLUSION Metastatic primary SGCTs are characterized by a specific miRNA expression pattern. Therefore, specific miRNAs could represent a new tool to predict the metastatic potential in SGCT patients.

Abstract
Purpose: To analyse the changing trends in penetrating keratoplasty indications between January 2011 and December 2018, at the Department of Ophthalmology, Saarland University Medical Center, Homburg/Saar, Germany. Patients and Methods: This is a retrospective review of 2123 corneal buttons of 1776 patients (1993 eyes, 56.0% males, age at the time of surgery 57.6 ± 18.7 years), who underwent penetrating keratoplasty (PKP) between January 2011 and December 2018. The classification was performed based on histological analysis and using the priority scheme of Brady et al., supplemented by a group of "failed endothelial keratoplasty grafts". Our groups were the following: pseudophakic or aphakic bullous keratopathy, regraft, failed endothelial keratoplasty graft, acute necrotizing and ulcerative keratitis, keratoconus, Fuchs' dystrophy, corneal dystrophy other than Fuchs', corneal scars and other diagnoses. Results: Between 2011 and 2018, keratoconus was the leading indication for PKP in 455 (21.5%) cases, followed by acute necrotizing and ulcerative keratitis in 384 (18.1%), regraft in 367 (17.3%), corneal scars in 350 (16.5%), pseudophakic or aphakic bullous keratopathy in 225 (10.6%), Fuchs' dystrophy in 194 (9.1%), other diagnoses in 64 (3.0%), corneal dystrophy other than Fuchs' in 52 (2.4%), and failed endothelial keratoplasty graft in 32 (1.5%) cases. Conclusions: With the introduction of posterior lamellar keratoplasty, keratoconus remains the leading PKP indication in our center with excimer laser-trephination on a routine basis. A trend towards increasing numbers can be observed regarding acute necrotizing and ulcerative keratitis patients and regrafts. However, the incidence of Fuchs' dystrophy decreased dramatically within PKP patients, with the introduction of posterior lamellar keratoplasty.

Abstract
Abstract
Background Chromosome 3q26 amplifications have been shown to represent a frequent alteration in various cancer entities including breast cancer. SEC62 - a 3q26 encoded gene - was identified as a potential oncogene and tumor-driver-gene for the pathogenesis of breast cancer. Although the precise physiological function of the respective protein Sec62 is not completely understood, it is hypothesized, that Sec62 induces an increased stress tolerance and enhances cell migration in SEC62 overexpressing cells resulting in a high rate of lymphatic metastasis and poorer overall prognosis in tumor tissue with a high Sec62 expression. We sought to further elucidate the function of Sec62 in breast cancer with special focus on its predictive role on the response to neoadjuvant chemotherapy. Materials and Methods All patients treated for primary breast cancer with neoadjuvant chemotherapy at the Department of Gynaecology and Obstetrics, Saarland University Hospital, Homburg, Germany between 01/2007 and 12/2018 were enrolled in this study. The study was approved by the Saarland institutional review board. Sec62 protein levels were analyzed in tumor tissue samples using immunohistochemistry (IHC). Sec62 immunoreactivity was evaluated by three independent examiners using the immunoreactive score (IRS) according to Remmele and Stegner (0-12). For the assessment of Sec62 protein expression in tumor cells, we rated Sec62 “negative” 0-3, “low” for a score of 4-8 and “high” for 9-12 as described in previous publications. IHC was performed on initial breast core biopsy (CB) tissue (pre-treatment) and on definite pathology specimen (PS) obtained during breast surgery after completion of neoadjuvant chemotherapy. Sec62 expression in both samples were compared and correlated with response to neoadjuvant chemotherapy evaluated pathologically using the semi-quantitative response to neoadjuvant chemotherapy scoring system by Sinn et al. ranging from 0 (no effect) to 4 (no tumor detectable). Additionally, Sec62 expression in tumor tissue was compared with the histologically tumor-free tissue of the same patient. Sec62 expression levels and correlation with response to neoadjuvant chemotherapy were compared using Wilcoxon signed-rank, Mann-Whitney and Pearson`s chi square test. Results 203 patients were assessed for eligibility. Nine cases were excluded, due to incomplete clinical information or insufficient slide quality, leaving 194 patients for final analysis. Median patient age was 54 (22-86) years and median response to neoadjuvant chemotherapy score of 2 (0-4). 20 patients (10 %) had luminal A, 46 (24 %) luminal B, 60 (31 %) Her2/neu positive and 68 (35 %) triple negative breast cancer. All analyzed slides showed an over-expression of Sec62 in breast cancer cells but no positive staining of physiologic breast tissue cells. Median Sec62 expression in core biopsies (CB) (8 (2-12)) was significantly higher compared to expression in final specimen (PS) (4 (0-12); p ≤ 0.01). Median difference between Sec62 expression of CB and PS was 2 (0-4). Regarding response to neoadjuvant chemotherapy patients with a low Sec62 expression in PS and a difference ≥ 6 between CB and PS showed a significant higher median response score compared to other patients (2 (0-4) vs. 1 (0-2); p ≤ 0.01; 4 (1-4) vs. 1 (0-4); p ≤ 0.01). When looking at breast cancer subtypes these effects were strongest in Her2/positive and triple negative patients and median Sec62 expression showed the highest decrease between CB and PS in these two subgroups (6 (-3-12); 2 (-6-12)). Conclusion We identified Sec62 as a potential biomarker for prediction of response to neoadjuvant chemotherapy in patients with primary breast cancer. This effect was observed to be strongest in patients with Her2/positive and triple negative breast cancer.

Abstract
PURPOSE To investigate the interaction between Wnt/β-catenin and estrogen signaling pathways in endometrial cancer (EC). METHODS 119 women were involved in this study, including 65 women with histologically confirmed EC and 54 healthy women as a control group. Serum protein levels of Dkk1 were measured using ELISA. Protein expression levels of Dkk1, β-catenin, ER-β isoforms (β1, β2, β5), and ER-α were tested in paraffin-embedded tissues using IHC. Gene expression levels of Dkk1, CTNNB, ESR1, and ESR2 were tested in fresh tumorous and normal endometrium tissues using RT-PCR. RESULTS EC patients had significantly higher serum levels of Dkk1 protein compared with healthy women. Dkk1 and β-catenin showed different expression pattern in tumor cells compared to it in normal cells at the protein level but not at the gene level. Protein expression levels of ERβ2 and ERα were significantly lower in tumor cells compared with tumor-adjacent normal cells. Increased protein expression levels of ERα were associated with favorable clinicopathological features and better overall survival rate (OS). Protein expression levels of ERα were correlated with protein expression levels of Dkk1 and cytoplasmic β-catenin. The association between ERα expression levels and OS was no more significant when tested in regard to Dkk1- and cytoplasmic β-catenin expression levels. CONCLUSIONS Our data demonstrated that Wnt/β-catenin and estrogen signaling systems are dysregulated in EC showing; for the first time, a potential crosstalk between certain components of these two pathways, which in turn has affected the specificity of these molecules in disease characteristics. Understanding the signaling networks in EC is crucial in designing clinical trials to evaluate the efficacy of molecular-targeted agents and providing more successful therapies in the future.

Abstract
PURPOSE In previous studies, we have shown that SEC62 has an essential function in cell migration, epithelial-to-mesenchymal transition, and endoplasmic reticulum stress tolerance of cancer cells. SEC62 expression correlated with distant and lymph node metastasis and poor outcome in different cancer entities. In this initial study, we investigated SEC62 expression and its possible role as a prognostic and predictive biomarker in breast cancer (BC). METHODS Formalin-fixed, paraffin-embedded tissue samples of 53 BC patients were analyzed by immunohistochemistry. The immunoreactive score (IRS) according to Remmele and Stegner was evaluated and correlated with clinico-pathological findings and overall survival (OS). RESULTS We found increased SEC62 protein levels in tumor tissue compared to tumor-free tissue samples from the same patients. Tumors with high SEC62 expression (IRS > 8), or containing isolated cells with high SEC62 staining intensity, independent of the IRS, had more frequently distant metastases (48.4% vs. 18.2%; p = 0.024 and 47.4 vs. 6.7%; p = 0.005, respectively). Overall survival was significantly worse in BC patients with high SEC62 expression (SEC62 IRS > 8) (54.8% vs. 81.8%; p = 0.011) and in cases with isolated high-intensity SEC62 staining cells independently of SEC62 IRS (55.3% vs 93.3%; p = 0.024). CONCLUSIONS We are the first to describe the SEC62 expression and its correlation to clinicopathological parameters in mammary carcinoma. Our results suggest that SEC62 expression may serve as a prognostic marker for patients with invasive ductal breast cancer.

Abstract
PURPOSE The aim of this study was to analyze the diagnostic performance of a newly established immunocytochemical dual-staining protocol for the simultaneous expression of SEC62 and Ki67 in vulvar liquid-based cytology specimens for the identification of vulvar intraepithelial neoplasia (VIN) and vulvar cancer. In addition, we investigated the p16/Ki67 dual stain, which has already been established in cervical cytology. MATERIALS AND METHODS For this pilot study, residual material from liquid-based cytology was collected retrospectively from 45 women. The presence of one or more double-immunoreactive cells was considered as a positive test result for Sec62/Ki67 and p16/Ki67 dual staining. The test results were correlated with the course of histology. RESULTS All cases of VIN and vulvar cancer were Sec62/Ki67 and p16/Ki67 dual-stain positive, and normal and low-grade squamous intraepithelial lesions were all negative. The sensitivity of cytology for VIN + cases was 100% (22/22), whereas punch biopsy classified one case of vulvar carcinoma as inflammation. All cases with high-intensity (grades 3 and 4) Sec62 staining in Sec62/Ki67-positive cases were carcinomas. CONCLUSIONS The results of this study demonstrate that Sec62/Ki67 and p16 Ki67 dual-staining cytology could be a promising adjunctive diagnostic tool for VIN and squamous cell carcinoma, in addition to standard histology.

Abstract
PURPOSE To generate and characterize 3D spheroid suspension cultures from radical prostatectomy (RP) specimens as a versatile model system for organ-confined prostate cancer (PCa). METHODS Cancerous tissue samples from RP specimens were excised by a uropathologist. Preparation of 3D spheroids was done by mechanical disintegration and limited enzymatic digestion followed by serial filtration through 100 μm- and 40 μm-cell strainers. Thereafter, spheroids were cultured in a modified stem cell medium and characterized by a live/dead assay, whole-spheroid immunohistochemistry (IHC; CK5, CK8, AMACR, PSA, Ki67, AR, αSMA, Vimentin, E-Cadherin) and PSA-measurements in culture medium. Furthermore, their response to pharmaceutical treatment with docetaxel, bicalutamide, enzalutamide and abiraterone was tested. RESULTS 173 RP cases were included. The median preoperative PSA-level was 16.12 ng/ml [range 0.99;345], the median Gleason score was 7b [6;10]. 64 cases were excluded due to low tumor content in frozen sections (43) or to insufficient spheroid formation (21). In the remaining 109 cases, spheroids formed successfully and stayed viable for up to several months. IHC analysis revealed AR-, CK8-, and AMACR-positivity in nearly all cases, while CK5-positive cells were detectable only occasionally as were α-SMA and Vimentin. E-Cadherin was positive in most cases. Furthermore, spheroids proved to be amenable to cryopreservation. While abiraterone had no effect and docetaxel only a moderate effect, spheroid viability was markedly reduced upon bicalutamide and enzalutamide treatment. CONCLUSIONS Multicellular 3D spheroids can be generated from patient-derived RP tissue samples and serve as an innovative in vitro model of organ-confined PCa.

Abstract
Flavonifractor plautii (formerly Eubacterium plautii) is an anaerobic gram positive rod shaped bacterium belonging to the family of Clostridiales, and a common member of the human gut microbiome. However, it is very rarely isolated from clinical human specimens, so data about its clinical significance are scarce. Here we report of a bloodstream infection due to F. plautii following gangrenous cholecystitis in a 69 year old man. After cholecystectomy and empirical antimicrobial treatment with ceftriaxone and metronidazole the patient recovered. F. plautii was the only bacterium detected in blood culture, suggesting that it might have been causative for cholecystitis. Antimicrobial resistance testing identified decreased susceptibilities against linezolid and penicillin indicating that a targeted therapy might be necessary. F. plautii can be considered a potential pathogen for cholecystitis.

Abstract
Uterine leiomyosarcoma (uLMS) is a rare entity among malignant gynecologic tumors with a very unfavorable prognosis and the highest prevalence in the pre- and peri-menopause. Only early-stage tumors have an acceptable prognosis, provided the patient has been treated without injuring the uterus. uLMS is often diagnosed accidentally and the correct diagnosis ishampered by equivocal features similar to the far more frequent benign uterine fibroids. Surgery is the basis of therapy, and it should be done in order to remove the uterus intact. As vaginal, abdominal, and endoscopic surgery - possibly including morcellation - are the methods of choice for the treatment of uterine fibroids, pre-operatively undiagnosed leiomyosarcoma detected by pathologic examination will have a worsened prognosis. Systemic treatment and radiotherapy are of no proven value in the adjuvant setting. Thus, there is strong need for a reliable pre-operative risk score for leiomyosarcoma in order to justify diagnostic means beyond clinical routine and to choose the correct surgical pathway. The clinical problems in the diagnosis of leiomyosarcoma and treatment are exemplified by a case report of a 30-year-old childless patient. Diagnostic tools as well as treatment options in adjuvant and palliative situations are reviewed.

Abstract
BACKGROUND Tumor-infiltrating lymphocytes (TIL) play an important role in the pathogenesis of renal cell carcinoma. Characterization of TIL requires efficient isolation procedures, especially in early stage disease when the tumor is of small in size. Conventional methods for isolating TIL are based on enzymatic tissue digestion, most frequently with collagenase. Collagenase isolation is limited by poor cell recovery, altered expression of cell-surface molecules, and impaired TIL-functionality. To overcome these limitations, we developed and optimized conditions for a robust collagenase-free mechanical procedure for improved isolation of TIL from renal cell carcinoma samples. METHODS TIL from tumor samples and T cells from peripheral blood were collected from 12 patients undergoing partial or radical nephrectomy. Samples were subjected to an enzymatic reference protocol and to a newly established mechanical isolation protocol. After viability staining, TIL-subpopulations were quantified and phenotyped by immunohistochemistry and flow-cytometric analysis, and were compared to characteristics of peripheral blood T cells. As a marker for TIL-functionality, T-cell cytokine induction was quantified after polyclonal stimulation. RESULTS We show that this new technique is rapid and allows identification of CD4 and CD8 T-cell subpopulations including CD4, CD8, and regulatory T cells expressing anergy markers such as programmed death-1 (PD-1) or B- and T-lymphocyte attenuator. When compared to the reference protocol involving collagenase digestion, the yield of TIL after mechanical isolation was higher and the expression of cell-surface markers was better preserved. Moreover, although antitumor activity was not assessed, mechanically isolated TIL are at least equally functional as T cells from peripheral blood, as polyclonal stimulation induced cytokines such as interferon-γ and tumor necrosis factor-α in both TIL and T cells from peripheral blood. CONCLUSION The mechanical procedure may be applied as a robust and rapid alternative to collagenase digestion for isolation of high amounts of phenotypically and functionally intact TIL from fresh tumor samples.

Abstract
BACKGROUND In this study, we aimed to establish a versatile in vivo model of prostate cancer, which adequately mimics intraprostatic tumor growth, and the natural routes of metastatic spread. In addition, we analyzed the capability of high-resolution ultrasonography (hrUS), in vivo micro-CT (μCT), and 9.4T MRI to monitor tumor growth and the development of lymph node metastases. METHODS A total of 5 × 105 VCaP cells or 5 × 105 cells of LuCaP136- or LuCaP147 spheroids were injected into the prostate of male CB17-SCID mice (n = 8 for each cell type). During 12 weeks of follow-up, orthotopic tumor growth, and metastatic spread were monitored by repetitive serum-PSA measurements and imaging studies including hrUS, μCT, and 9.4T MRI. At autopsy, primary tumors and metastases were harvested and examined by histology and immunohistochemistry (CK5, CK8, AMACR, AR, Ki67, ERG, and PSA). From imaging results and PSA-measurements, tumor volume doubling time, tumor-specific growth rate, and PSA-density were calculated. RESULTS All 24 mice developed orthotopic tumors. The tumor growth could be reliably monitored by a combination of hrUS, μCT, MRI, and serum-PSA measurements. In most animals, lymph node metastases could be detected after 12 weeks, which could also be well visualized by hrUS, and MRI. Immunohistochemistry showed positive signals for CK8, AMACR, and AR in all xenograft types. CK5 was negative in VCaP- and focally positive in LuCaP136- and LuCaP147-xenografts. ERG was positive in VCaP- and negative in LuCaP136- and LuCaP147-xenografts. Tumor volume doubling times and tumor-specific growth rates were 21.2 days and 3.9 %/day for VCaP-, 27.6 days and 3.1 %/day for LuCaP136- and 16.2 days and 4.5 %/day for LuCaP147-xenografts, respectively. PSA-densities were 433.9 ng/mL per milliliter tumor for VCaP-, 6.5 ng/mL per milliliter tumor for LuCaP136-, and 11.2 ng/mL per milliliter tumor for LuCaP147-xenografts. CONCLUSIONS By using different monolayer and 3D spheroid cell cultures in an orthotopic xenograft model, we established an innovative, versatile in vivo model of prostate cancer, which enables the study of both intraprostatic tumor growth as well as metastatic spread to regional lymph nodes. HrUS and MRI are feasible tools to monitor tumor growth and the development of lymph node metastases while these cannot be visualized by μCT.

Abstract
In squamous cell carcinoma (SCC) of the lung, mutations within the genes of fibroblast growth factor receptors (FGFR) such as K660N/K660E in FGFR2 and R248C/S249C in FGFR3 and FGFR1 gene amplification have been described, but their prognostic relevance still remains unclear. In order to detect the mutation frequencies and to define their prognostic value for associated clinicopathologic features and survival of patients, resected ΔNp63/p40-positive SCC of the lung (n = 101) were screened for FGFR1 gene amplification by fluorescence in situ hybridization performed on formalin-fixed paraffin embedded tissues and for the presumed driver mutations in genes of FGFR2 and FGFR3 by PCR and Sanger sequencing. Twenty-two of 101 SCCs (22%) were positive for amplification based on a FGFR1/centromere (chromosome 8) ratio > 2.0 or higher. In advanced tumor stages (III-IV), the overall survival of patients carrying FGFR1 gene amplification was significantly higher (p = 0.006). Among women, FGFR1 gene amplification was significantly associated with longer overall survival (p = 0.023). The presence of FGFR1 gene amplification was associated with patient age (65 versus 69 years, p = 0.046), but not with gender, tumor stage, histologic subtype, tumor grade, or ΔNp63/p40 immunoreactivity. The S249C mutation in the FGFR3 gene was identified in one out of 101 SCCs (1%); the K600N, K660E, or R248C mutations were not identified. These results suggest that FGFR1 gene amplification is a frequent alteration in SCC of the lung and appears not to be a negative but rather a favorable prognostic marker for women and particularly for patients with advanced SCC of the lung (stage III-IV).

Abstract
The long non-coding RNA (lncRNA) H19 represents a maternally expressed and epigenetically regulated imprinted gene product and is discussed to have either tumor-promoting or tumor-suppressive actions. Recently, H19 was shown to be regulated under inflammatory conditions. Therefore, aim of this study was to determine the function of H19 in hepatocellular carcinoma (HCC), an inflammation-associated type of tumor. In four different human HCC patient cohorts H19 was distinctly downregulated in tumor tissue compared to normal or non-tumorous adjacent tissue. We therefore determined the action of H19 in three different human hepatoma cell lines (HepG2, Plc/Prf5, and Huh7). Clonogenicity and proliferation assays showed that H19 overexpression could suppress tumor cell survival and proliferation after treatment with either sorafenib or doxorubicin, suggesting chemosensitizing actions of H19. Since HCC displays a highly chemoresistant tumor entity, cell lines resistant to doxorubicin or sorafenib were established. In all six chemoresistant cell lines H19 expression was significantly downregulated. The promoter methylation of the H19 gene was significantly different in chemoresistant cell lines compared to their sensitive counterparts. Chemoresistant cells were sensitized after H19 overexpression by either increasing the cytotoxic action of doxorubicin or decreasing cell proliferation upon sorafenib treatment. An H19 knockout mouse model (H19Δ3) showed increased tumor development and tumor cell proliferation after treatment with the carcinogen diethylnitrosamine (DEN) independent of the reciprocally imprinted insulin-like growth factor 2 (IGF2). In conclusion, H19 suppresses hepatocarcinogenesis, hepatoma cell growth, and HCC chemoresistance. Thus, mimicking H19 action might be a potential target to overcome chemoresistance in future HCC therapy.

Abstract
In comparison with other tumor entities there is no common generally accepted grading system for lung cancer with clearly defined criteria and clinical relevance. In the recent fourth edition of the World Health Organization (WHO) classification from 2015 of tumors of the lungs, pleura, thymus and heart, there is no generally applicable grading for pulmonary adenocarcinomas, squamous cell carcinomas or rarer forms of carcinoma. Since the new IASLC/ATS/ERS classification of adenocarcinomas published in 2011, 5 different subtypes with significantly different prognosis are proposed. This results in an architectural (histologic) grading, which is usually applied to resection specimens. For squamous cell carcinoma the number of different histological subtypes in the new WHO classification was reduced compared to earlier versions but without a common grading system. In recent publications nesting and budding were proposed as the main (histologic) criteria for a grading of squamous cell carcinomas. The grading of neuroendocrine tumors (NET) of the lungs in comparison with NET in other organs is presented in a separate article in this issue. Certain rare tumor types are high grade per definition: small cell, large cell and pleomorphic carcinomas, carcinosarcomas and pulmonary blastomas. In the future it is to be expected that these developments will be further refined, e. g. by adding further subtypes for adenocarcinomas and cytologic and/or nuclear criteria for adenocarcinoma and/or squamous cell carcinomas.
