Abstract
OBJECTIVES Lung carcinoids and atypical hamartomas may be difficult to differentiate but require different treatment. The aim was to differentiate these tumors using contrast-enhanced CT semantic and radiomics criteria. METHODS Between November 2009 and June 2020, consecutives patient operated for hamartomas or carcinoids with contrast-enhanced chest-CT were retrospectively reviewed. Semantic criteria were recorded and radiomics features were extracted from 3D segmentations using Pyradiomics. Reproducible and non-redundant radiomics features were used to training a random forest algorithm with cross-validation. A validation-set from another institution was used to evaluate of the radiomics signature, the 3D 'median' attenuation feature (3D-median) alone and the mean value from 2D-ROIs. RESULTS Seventy-three patients (median 58 years [43‒70]) were analyzed (16 hamartomas; 57 carcinoids). The radiomics signature predicted hamartomas vs carcinoids on the external dataset (22 hamartomas; 32 carcinoids) with an AUC = 0.76. The 3D-median was the most important in the model. Density thresholds < 10 HU to predict hamartoma and > 60 HU to predict carcinoids were chosen for their high specificity > 0.90. On the external dataset, sensitivity and specificity of the 3D-median and 2D-ROIs were, respectively, 0.23, 1.00 and 0.13, 1.00 < 10 HU; 0.63, 0.95 and 0.69, 0.91 > 60 HU. The 3D-median was more reproducible than 2D-ROIs (ICC = 0.97 95% CI [0.95‒0.99]; bias: 3 ± 7 HU limits of agreement (LoA) [- 10‒16] vs. ICC = 0.90 95% CI [0.85‒0.94]; bias: - 0.7 ± 21 HU LoA [- 4‒40], respectively). CONCLUSIONS A radiomics signature can distinguish hamartomas from carcinoids with an AUC = 0.76. Median density < 10 HU and > 60 HU on 3D or 2D-ROIs may be useful in clinical practice to diagnose these tumors with confidence, but 3D is more reproducible. CRITICAL RELEVANCE STATEMENT Radiomic features help to identify the most discriminating imaging signs using random forest. 'Median' attenuation value (Hounsfield units), extracted from 3D-segmentations on contrast-enhanced chest-CTs, could distinguish carcinoids from atypical hamartomas (AUC = 0.85), was reproducible (ICC = 0.97), and generalized to an external dataset. KEY POINTS • 3D-'Median' was the best feature to differentiate carcinoids from atypical hamartomas (AUC = 0.85). • 3D-'Median' feature is reproducible (ICC = 0.97) and was generalized to an external dataset. • Radiomics signature from 3D-segmentations differentiated carcinoids from atypical hamartomas with an AUC = 0.76. • 2D-ROI value reached similar performance to 3D-'median' but was less reproducible (ICC = 0.90).

Abstract
Perivascular epithelioid cell tumors (PEComas) are very rare mesenchymal neoplasms, composed of histologically and immunohistochemically distinctive cells that form a sheet-like appearance around vessel lumens. Although most are benign, a malignant subset does exist, complicating clinical diagnostic efforts. Proper evaluation and management are thus essential for long-term patient survival. Herein, we present a rare case of a benign pulmonary PEComa that was diagnosed postoperatively in a 45-year-old woman.

Abstract
In recent years, with the widespread application of bronchial sleeve resection, many studies have shown that, compared to pneumonectomy, bronchial sleeve resections can preserve more lung parenchyma, improve quality of life of patients, and significantly reduce postoperative complications and mortality rates. In this review, we discuss bronchial segmental sleeve resections with variations in the light of literature data.

Abstract
BACKGROUND Extramedullary plasmacytoma (EMP) is a rare kind of soft tissue plasma cell neoplasm without bone marrow involvement; this type of plasma cell neoplasm involves a lack of other systemic characteristics of multiple myeloma. Primary pulmonary plasmacytoma (PPP), with no specific clinical manifestations, is an exceedingly rare type of EMP. Because of its complexity, PPP is often difficult to diagnose, and there is no report in the literature on cases accompanied by overlap syndrome (OS).
CASE SUMMARY A 61-year-old woman without a familial lung cancer history was admitted to our hospital in 2018, for intermittent cough, expectoration, and a stuffy feeling in the chest for 50 years; these symptoms appeared intermittently, especially occurred after being cold, and had been aggravated for the last 10 d. She was diagnosed with pulmonary fibrosis and emphysema, bronchiectasis, OS, and autoimmune hepatic cirrhosis in 2017. A pulmonary examination revealed rough breath sounds in both lungs; other physical examinations found no obvious abnormalities. A routine laboratory work-up showed decreased haemoglobin, increased ESR, and abnormal GGT, ALT, IgG, γ-globulin, κ-light chain, λ-light chain, rheumatoid factor, and autoimmune antibodies. Emission computed tomography demonstrated abnormally concentrated 99mTc-MDP. Chest computed tomography revealed a soft tissue mass in the middle and lower lobes of the right lung. After right middle and inferior lobe resection with complete mediastinal lymph node dissection, immunohistochemical analysis revealed an isolated pulmonary plasmacytoma. The patient received chemotherapy for more than 1.5 years and remains in good general condition.
CONCLUSION PPP is a type of EMP, and we report an exceedingly rare presentation of PPP accompanied by OS.

Abstract
BACKGROUND Phyllodes tumours (PTs) are fibroepithelial breast tumours, which can be classified as benign, borderline or malignant, according to their histological characteristics. While various huge borderline or malignant PTs have been previously described, a benign PT with a pulmonary nodule mimicking malignancy has not yet been reported. In order that doctors may have a comprehensive understanding of super-giant benign PTs (≥ 20 cm), we also performed a literature review to summarize the clinical features, differential diagnosis, and treatment of this disease.
CASE SUMMARY A 42-year-old woman with severe anaemia presented with a rapidly enlarging right breast mass, measuring approximately 30 cm × 25 cm × 20 cm that was first noticed 1 year previously. A region of skin ulceration and necrosis (20 cm × 15 cm) was observed on the lateral side of the mass. Computed tomography (CT) of the chest revealed a pulmonary nodule, which initially suggested a diagnosis of metastasis. CT showed that the boundaries between the pectoralis major and the mass were blurred, which was presumed to be due to tumour invasion. However, two core needle biopsies of the mass showed no evidence of malignancy. Following these results, the tumour was removed by mastectomy of the right breast. Interestingly, postoperative pathology finally proved the diagnosis of a benign PT. After 1 year of follow-up, wedge resection of the small pulmonary nodule was performed, and it was confirmed that the lung nodule was actually adenocarcinoma rather than metastatic breast cancer. The patient recovered very well without any postoperative treatment.
CONCLUSION This case is unique in that the giant breast mass initially mimicking a malignant clinical presentation was eventually pathologically confirmed to be a benign PT, which misled the diagnosis and complemented the atypical features of benign PTs. The pathological and immunohistochemical results were important in the differential diagnosis. In addition, total mastectomy should be recommended due to difficulty in the precise diagnosis of PTs, especially in large breast masses. In the literature, almost one-half of super-giant benign cases were thought to be malignant tumours before surgery. This finding is a reminder to consider all conditions in order to make an accurate diagnosis and avoid excessive treatment.

Abstract
Carcinoid tumors are generally indolent neoplasms. Brain metastases are rare and when present, yield a poor prognosis. We present the case of a 76-year old female surgically treated for an atypical bronchial carcinoid, staged as T2aN0M0G2. Without further adjuvant treatment she remained stable for four years, when she presented with headaches and gait imbalance. Brain MRI revealed a midline, intra-axial infratentorial lesion that was completely removal, of which histolology confirmed a carcinoid metastasis. At 14 months of follow-up, the patient showed no signs of systemic disease or brain recurrence, and thus no adjuvant radiotherapy was prescribed.

Abstract
BACKGROUND For most colorectal cancer patients with initial lung metastasis (LM), the only suitable treatments are palliative, including palliative local therapy and pharmacotherapy. We investigated the role of palliative local treatments in prolonging survival and the efficacy of different pharmacotherapies. PATIENTS AND METHODS After performing a medical record review of 2233 patients with metastatic colorectal cancer, 684 were identified as having LM. Their clinicopathologic characteristics, treatment patterns, and outcomes were analyzed retrospectively. RESULTS For nonresectable initial LM, patients receiving palliative local therapy had significantly longer median progression-free survival (PFS) and overall survival (OS) than those treated with pharmacotherapy alone: PFS 16.1 months versus 7.4 months (P < .001) and OS 51.8 months versus 23.8 months (P < .001), respectively. Cox multivariate analysis confirmed the survival benefit induced by palliative local therapy. Chemonaive patients receiving single-agent fluoropyrimidine had shorter PFS and longer OS compared to oxaliplatin- or irinotecan-based doublets when used as first-line treatment (PFS 4.8, 7.4, and 7.3 months; and OS 28.7, 21.2, and 20.1 months, respectively); however, these differences were not statistically significant. The addition of targeted agents to cytotoxic drugs prolonged PFS (10.5 vs. 7.2 months, P = .005) but not OS (27.8 vs. 21.2 months, P = .454). Carcinoembryonic antigen level, LM-associated symptoms, extrapulmonary disease, and histopathologic type were independent pretreatment prognostic factors. CONCLUSION Local treatments of LM may confer a survival benefit in the palliative setting. First-line single-agent fluoropyrimidine may be used in patients with good prognosis.

Abstract
Peripheral blood mononuclear cells (PBMC) represent an easily available population of cells for the studies on remote effects of lung cancer. NADH dehydrogenase (ubiquinone) Fe-S protein-1 (Ndufs1), a marker of mitochondrial complex I, and mitochondrially encoded cytochrome c oxidase 1 (MTCO1), a marker of complex IV, may participate in cognitive decline during the course of lung cancer. In this study, Ndufs1 and MTCO1 expression in PBMC was evaluated by means of ELISA in 80 lung cancer patients. Mini-Mental State Examination (MMSE) were conducted Trail Making Tests (TMT-A and TMT-B) at baseline and after the 6 months' follow-up. Autoantibodies were identified by means of indirect immunofluorescence and line blot. We found that enhanced levels of Ndufs1 in PBMC were related to impaired cognitive performance; TMT-A of 13.6 ± 3.1 s and TMT-B of 162.5 ± 46.4 s compared with 8.6 ± 4.5 s (p = 0.003) and 124.8 ± 51.8 s (p < 0.05), respectively, in the case of low Ndufs-1 levels. The Ndufs1 expression at baseline was associated with MMSE - τb (Kendall's tau-b) = -0.31; p = 0.024; TMT-A - τb = 0.30; p = 0.001), and TMT-B - τb = 0.199; p = 0.012) after the 6 months' follow-up. Higher MTCO1 expression was accompanied by worse TMT-A results than in case of inhibited MTCO1; 11.1 ± 5.8 s vs. 8.5 ± 4.1 s; respectively; p = 0.048. MTCO1 expression was correlated with TMT-A results (τb = 0.17; p = 0.034) at baseline. We conclude that stimulation of PBMC mitochondrial function in lung cancer patients is associated with cognitive impairment. Mitochondrial dysfunction in PBMC may reflect cytotoxicity responsible for neurological deficits.

Abstract
A large variety of rare benign and malignant tumors may sporadically affect the lung. Computed tomography (CT) findings of unusual primary lung tumors are often nonspecific. However, there are some rare pulmonary tumors with imaging features overlapping those of other conditions, thus making radiologic diagnosis challenging. The aim of this review was to correlate CT and histopathological features of a variety of unusual lung tumors to better clarify when and to what extent radiological diagnosis is reliable.

Abstract
Primary pulmonary chondrosarcoma is a rare neoplasm that usually grows slowly, metastasizes late, and responds well to excision when localized. Herein, we present a 59-year-old man who manifested with hemoptysis, cough and dyspnea with a hemithorax mass. A chest computed tomography scan demonstrated a fast-growing mass in the right upper lobe, and the enhancement was partially heterogeneous. Bronchoscopy revealed a hemorrhagic neoplasm in the right upper bronchus. A bronchoscopy biopsy specimen revealed a variety of tissues, including mucoid cartilage, fibers, respiratory epithelium and squamous epithelium. Because malignancy was suspected, the patient underwent a right upper sleeve lobectomy with mediastinal lymphadenectomy. Macroscopically, we observed a firm white mass 9.5 cm in diameter with a central area of necrosis. Histopathology revealed neoplastic chondrocytes with enlarged and hyperchromatic nuclei in the myxoid matrix. The tumors were positive for S-100. The patient was diagnosed with tracheobronchial myxoid chondrosarcoma. Lymph node dissection indicated no metastasis. The tumor grows slowly in the initial symptom-free phase when localized. Then, a symptomatic phase ensues, during which the tumor progresses rapidly. The patient displayed pulmonary and subcutaneous skull metastases eight months after operation and was treated with adriamycin and ifosfamide chemotherapy.

Abstract
Angiomatoid fibrous histiocytoma (AFH), a rare soft tissue tumor of borderline malignancy, typically occurs in the subcutis of the accessible soft tissues, most often in children and young adults. Lymph node and/or distant metastasis is seen in less than 2% of patients with AFH. Exceptionally rare examples of AFH have been reported in visceral locations, including the lung. We report a genetically confirmed primary pulmonary AFH in a 70-year-old woman with mediastinal lymph node metastasis, representing to the best of our knowledge the first report of metastases from a visceral AFH.

Abstract
Cognitive impairment develops as a clinical manifestation of immune-mediated indirect effects of malignancy in lung cancer patients. This study aimed to evaluate the effects of humoral immune response on cognition in lung cancer patients. Fifty-one lung cancer patients were subjected to neurological examination: Mini Mental State Examination (MMSE), Trail Making Test (TMT), and Hamilton scale. The Psychology Experiment Building Language software was used for the evaluation of digit span, simple reaction time (SRT), and choice reaction time (CRT) tests. Serum samples were tested for the presence of onconeuronal antibodies and antineural antibodies. The results demonstrate that autoantibodies were found in 31 % patients. MMSE scores were lower (26.7 ± 2.7) in seropositive patients than in seronegative subjects (28.7 ± 1.2; p = 0.013). Executive functions were also influenced by the presence of autoantibodies. The humoral immune response in lung cancer patients affected both SRT and CRT. We conclude that the humoral immune response in lung cancer patients is associated with cognitive impairment. Cognitive impairment is associated with both specific reactions against onconeuronal or antineural antigens and non-organ specific reactions against nucleosome antigens.

Abstract
OBJECTIVE Evaluate the restrictiveness of selection criteria for lung resection in lung cancer patients over 80 years of age compared to those applied in younger patients. Compare and analyze 30-day mortality and postoperative complications in both groups of patients. METHODS Case-controlled retrospective analysis. STUDY POPULATION Consecutive patients undergoing elective anatomical lung resection. Population was divided into octogenarians (cases) and younger patients (controls). Variables determining surgical risk (BMI, FEV1%, postoperative FEV1%, FEV1/FVC, DLCO and pneumonectomy rate) were compared using either Wilcoxon or Chi-squared tests. Thirty-day mortality and morbidity odds ratio were calculated. A logistic regression model with bootstrap resampling was constructed, including postoperative complications as dependent variable and age and post-operative FEV1% as independent variables. Data were retrieved from a prospective database. RESULTS No statistically significant differences were found in BMI (P=.40), FEV1% (P=.41), postoperative FEV1% (P=.23), FEV1/FVC (P=.23), DLCO (P=.76) and pneumonectomy rate (P=.90). Case mortality was 1.85% and control mortality was 1.26% (OR: 1.48). Cardiorespiratory complications occurred in 12.80% of younger subjects and in 13.21% of patients aged 80 years or older. (OR: 1.03). In the logistic regression, only FEV1% was related to postoperative complications (P<.005). CONCLUSION Selection criteria for octogenarians are similar to those applied in the rest of the population. Advanced age is not a factor for increased 30-day mortality or postoperative morbidity.
