Cardioneuroablation for treatment of carotid sinus syndrome secondary to oropharyngeal squamous cell cancer.

Head and neck tumors can rarely cause carotid sinus syndrome and this often resolves by surgical intervention or palliative chemoradiotherapy. If these modalities are not an option or are ineffective, the most preferred treatment is permanent pacemaker therapy. Here, we present the first case of cardioneuroablation treatment performed in patient with oropharyngeal squamous cell cancer who developed recurrent asystole and syncope attacks due to compression of the carotid sinus on neck movement.

Fibroepithelial urethral polyp with minor prostatic glands in an older man.

We describe a man in his 60s with an incidentally detected urethral polyp located in the middle section of his penile shaft. The patient had been suffering from urinary retention for 9 years due to benign prostatic hyperplasia. He was initiated on clean intermittent catheterisation to drain urine 1 year before the detection of the urethral polyp. Holmium laser nucleation of the prostate was performed, and an anterior urethral polyp (5 mm in diameter) was resected. Pathology indicated that the urethral polyp was a fibroepithelial polyp with prostate-specific antigen-immunoreactive heterotopic prostatic glands. There were no problems with urination 6 months after surgery. Fibroepithelial urethral polyps are usually congenital and are rarely described in adults. The clinicopathological features of this polyp, with its uniquely associated minor prostatic glands, are presented.

Clinical impact of SARS-CoV-2 infection among patients with vulvar cancer: the Gemelli Vul.Can multidisciplinary team.

BACKGROUND: 'Severe acute respiratory syndrome coronavirus-2' (SARS-CoV-2) infection has dramatically affected the management of patients with cancer, who are most vulnerable to the consequences of the infection. Patients with vulvar cancer are frequently elderly and affected by multiple co-morbidities, thus representing a particularly frail population. OBJECTIVE: To assess the clinical impact of the SARS-CoV-2 infection among patients scheduled for treatment for active vulvar cancer. METHODS: Data on patients with vulvar tumors referred to Fondazione Policlinico Universitario Agostino Gemelli IRCCS between February 2020 and July 2021 were retrospectively analyzed. Patients with a positive reverse transcription polymerase chain reaction in nasopharyngeal swab were considered as positive for SARS-Cov-2. RESULTS: One hundred and ninety-one patients with vulvar cancer were evaluated and scheduled for treatment. The median age was 72 years (range 35-94). Seven (3.7%) patients were diagnosed with SARS-Cov-2 infection: three (42.9%) had their treatment delayed, with no apparent consequences, two (28.6%) had their treatment delayed and later abandoned because of clinical worsening due to oncologic disease progression, and two (28.6%) contracted the infection in the post-operative period and died due to respiratory complications. CONCLUSIONS: In most cases the infection had major clinical implications, being associated with significant delays in oncologic treatments and extremely high mortality when contracted in the post-operative period.

Pretreatment Adherence to a Priori-Defined Dietary Patterns Is Associated with Decreased Nutrition Impact Symptom Burden in Head and Neck Cancer Survivors.

Dietary intake is understood to contribute to nutrition impact symptoms (NIS) in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to evaluate the performance of four a priori-defined diet quality indices on the presence of NIS 1 year following diagnosis using data on 323 participants from the University of Michigan Head and Neck Specialized Program of Research Excellence (UM-SPORE). Pretreatment dietary intake was measured before treatment initiation using a food frequency questionnaire. NIS were measured along seven subdomains. Multivariable binary logistic regression models were constructed to evaluate relationships between pretreatment scores on a priori-defined diet quality indices (AHEI-2010, aMED, DASH, and a low-carbohydrate score) and the presence of individual symptoms in addition to a composite "symptom summary score" 1-year postdiagnosis. There were several significant associations between different indices and individual NIS. For the symptom summary score, there were significant inverse associations observed for aMED (ORQ5-Q1: 0.36, 95% CI: 0.14-0.88, ptrend = 0.04) and DASH (ORQ5-Q1: 0.38, 95% CI: 0.15-0.91, ptrend = 0.02) and the presence of NIS 1-year postdiagnosis. Higher adherence to the aMED and DASH diet quality indices before treatment may reduce NIS burden at 1-year postdiagnosis.

Assessment of Intratumoral and Peritumoral Computed Tomography Radiomics for Predicting Pathological Complete Response to Neoadjuvant Chemoradiation in Patients With Esophageal Squamous Cell Carcinoma.

Importance: For patients with locally advanced esophageal squamous cell carcinoma, neoadjuvant chemoradiation has been shown to improve long-term outcomes, but the treatment response varies among patients. Accurate pretreatment prediction of response remains an urgent need. Objective: To determine whether peritumoral radiomics features derived from baseline computed tomography images could provide valuable information about neoadjuvant chemoradiation response and enhance the ability of intratumoral radiomics to estimate pathological complete response. Design, Setting, and Participants: A total of 231 patients with esophageal squamous cell carcinoma, who underwent baseline contrast-enhanced computed tomography and received neoadjuvant chemoradiation followed by surgery at 2 institutions in China, were consecutively included. This diagnostic study used single-institution data between April 2007 and December 2018 to extract radiomics features from intratumoral and peritumoral regions and established intratumoral, peritumoral, and combined radiomics models using different classifiers. External validation was conducted using independent data collected from another hospital during the same period. Radiogenomics analysis using gene expression profile was done in a subgroup of the training set for pathophysiological explanation. Data were analyzed from June to December 2019. Exposures: Computed tomography-based radiomics. Main Outcomes and Measures: The discriminative performances of radiomics models were measured by area under the receiver operating characteristic curve. Results: Among the 231 patients included (192 men [83.1%]; mean [SD] age, 59.8 [8.7] years), the optimal intratumoral and peritumoral radiomics models yielded similar areas under the receiver operating characteristic curve of 0.730 (95% CI, 0.609-0.850) and 0.734 (0.613-0.854), respectively. The combined model was composed of 7 intratumoral and 6 peritumoral features and achieved better discriminative performance, with an area under the receiver operating characteristic curve of 0.852 (95% CI, 0.753-0.951), accuracy of 84.3%, sensitivity of 90.3%, and specificity of 79.5% in the test set. Gene sets associated with the combined model mainly involved lymphocyte-mediated immunity. The association of peritumoral area with response identification might be partially attributed to type I interferon-related biological process. Conclusions and Relevance: A combination of peritumoral radiomics features appears to improve the predictive performance of intratumoral radiomics to estimate pathological complete response after neoadjuvant chemoradiation in patients with esophageal squamous cell carcinoma. This study underlines the significant application of peritumoral radiomics to assess treatment response in clinical practice.

Left atrial tumor thrombus with emboli to the brain and distal extremities: A case report.

Cardiac metastases are an uncommon phenomenon associated with neoplasms from a variety of primary sites. Pulmonary involvement often accompanies metastases involving the left atrium or ventricle and clinical presentation may be associated with stroke or emboli involving distal sites. We report a patient who presented acutely to the Emergency Department with symptoms of a cerebrovascular accident and bilateral cold pulseless lower extremities. Computerized Tomographic (CT) angiogram of the chest, abdomen, pelvis and lower extremities disclosed pulmonary veins with large filling defects in the right superior and inferior vessels as well as the left atrium and atrial appendage. Mediastinal and hilar adenopathy was detected. The patient had a history of tonsillar squamous cell carcinoma eighteen months prior. The patient underwent operative intervention with removal of a large left intra-atrial mass, histologic evaluation of which demonstrated groups of malignant squamous cells meshed in fibrin clot. The patient died three days post operatively due to multiple brain infarctions.

Erythroderma as first manifestation of squamous cell lung cancer: rare case report

Abstract Erythroderma as the first manifestation of a solid organ malignancy is rare. The underlying cancer is a challenging condition to diagnose. There are a few cases of erythroderma in cancer patients reported in the literature. We here describe the case of a 70-year-old man who presented with asthenia, weight loss, dry cough and total body erythema with desquamation over the past month. A chest computed tomography scan showed a nodular lesion, which was finally diagnosed as a squamous cell lung carcinoma. To our knowledge, as an erythroderma presentation, only 13 cases have been reported in the literature. This case report demonstrates the need to search for a neoplasm in patients presenting with erythroderma, particularly in the presence of accompanying debilitating symptoms.

Chronic Obstructive Pulmonary Disease in Lung Cancer Patients: Prevalence, Underdiagnosis, and Clinical Characterization.

BACKGROUND: Lung cancer (LC) and chronic obstructive pulmonary disease (COPD) are associated with increased morbidity and mortality. The differential clinical and functional features among LC patients with or without COPD have not been defined. OBJECTIVES: The aims of this study were to examine the prevalence and underdiagnosis rate of COPD in LC patients and to compare the clinical and functional features of LC patients with and without COPD. METHODS: We designed a multicenter hospital-based study including all LC cases diagnosed from January 2014 to August 2016. We assessed epidemiological, clinical, radiological, functional, and histological variables in all cases. RESULTS: We recruited 602 patients with LC, most of them men (77.9%), with a median age of 67 ± 15 years. The COPD prevalence among LC patients was 51.5%, with a underdiagnosis rate of 71.6%. The LC+COPD patients were older and the proportion of men was higher compared with the LC-only patients. The LC+COPD patients had more pack-years, more squamous LC, a lower monoxide transfer coefficient (KCO), and higher Charlson index scores than patients with LC only. The median survival of LC-only patients was 37% longer than that of LC+COPD patients (22 vs. 16 months), but this difference was not statistically significant. CONCLUSIONS: Among LC patients, COPD is prevalent and underdiagnosed. Patients with LC+COPD more often have squamous LC, have greater comorbidities, and have a lower KCO. More effort should be made for an early diagnosis of COPD to select patients at higher risk of developing LC.

Lymphoepithelioma-like carcinoma of the urinary bladder: A case report.

We report a case of lymphoepithelioma-like carcinoma of the urinary bladder in an elderly female patient. A 97-year old woman presented with hematuria, and an ultrasonographic urinary study showed a localized tumor in the trigone region of the urinary bladder. A transurethral resection revealed a mixed tumor formed by high-grade transitional carcinoma and lymphoepithelioma-like carcinoma that had infiltrated into the muscular propria. We describe the clinicopathological, morphological and immunohistochemical features of this tumor and briefly discuss its differential diagnosis and biological behavior.

Impact of pre-operative body mass index in head and neck cancer patients undergoing microvascular reconstruction.

OBJECTIVES: To analyse the relationship of pre-operative body mass index with surgical complications and oncological outcomes in patients undergoing microvascular reconstruction for head and neck squamous cell cancer. METHOD: A retrospective review was conducted of 259 patients who underwent microvascular free flap reconstruction after head and neck ablative surgery. RESULTS: Mean body mass index was 22.48 kg/m2. There were no correlations between body mass index and: flap failure (p = 0.739), flap ischaemia (p = 0.644), pharyngocutaneous fistula (p = 0.141) or wound infection (p = 0.224). The five-year disease-specific survival rate was 63 per cent. On univariate analysis, the five-year disease-specific survival rate was significantly correlated with pre-operative body mass index, based on Kaplan-Meier survival curves (p = 0.028). The five-year disease-specific survival rates in underweight, normal weight, overweight and obese groups were 47 per cent, 55 per cent, 65 per cent and 80 per cent, respectively. CONCLUSION: Pre-operative body mass index was a useful predictor for recurrence and survival in patients who underwent microvascular reconstruction for head and neck squamous cell cancer.

Gene Variability Between Perineural-positive and Perineural-negative Squamous Cell Skin Cancers.

AIM: To identify differentially expressed genes (DEGs) between perineural invasion-positive (PP) and -negative (PN) cutaneous squamous cell cancers (CSCC). MATERIALS/METHODS: Forty CSCC samples with and without perineural invasion were processed for RNA isolation and hybridization to Affymetrix-U219 DNA microarrays. Raw gene expression data were normalized by Robust Multi-array Averaging (RMA) and log2 transformed. Gene expression-based classification models were created and accuracies evaluated using leave-one-out cross-validation. RESULTS: At a stringent limma p-value (p<0.001), 24 genes were differentially expressed between PP and PN samples. The cross-validated performance of the eight classification models exhibited a mean accuracy of 85-95%. Diagonal linear discriminant was most accurate at 95%, followed by Bayesian compound covariate at 94%. The poorest accuracy (85%) was observed for 1-Nearest neighbor and Support vector machines. CONCLUSION: Gene expression may distinguish between PP and PN CSCC. Understanding these gene patterns may potentiate more timely diagnosis of perineural invasion and guide comprehensive therapies.
