Abstract
Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare primary skin cancer, with an annual incidence of 1/100,000 and about 85 cases published in the literature. It is considered the cutaneous counterpart of undifferentiated nasopharyngeal carcinoma (UNC, Schmincke-Regaud tumor) but has no association with EBV. We present an interesting case with features of LELCS in a 93-year-old man, right frontal-orbital region, diagnosed histologically and with immunohistochemical features. We also emphasize contrasting morphologic features for correct nosographic classification and address current issues, suggesting potential insights. Finally, we briefly reviewed other cases described in the literature.

A systematic review and meta-analysis. Sci Rep 2023; 13:8523. [PMID: 37237097 DOI: 10.1038/s41598-023-35503-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 05/18/2023] [Indexed: 05/28/2023] Open
Abstract
Head and Neck Cancer (HNC) is a globally rare cancer that includes a variety of tumors affecting the upper aerodigestive tract. It presents with difficulty breathing or swallowing and is mainly treated with radiation therapy, chemotherapy, or surgery for tumors that have spread locally or throughout the body. Alternatively, exercise can be used during cancer treatment to improve function, including pain relief, increase range of motion and muscle strength, and reduce cancer-related fatigue, thereby enhancing quality of life. Although existing evidence suggests the adjunctive use of exercise in other cancer types, no previous studies have examined the effects on HNC survivors. The aim of this meta-analysis was to quantify the effect of exercise-based rehabilitation on functionality and quality of life in HNC survivors who underwent surgery and/or chemoradiotherapy. A systematic review and meta-analysis were carried out following PRISMA statement and registered in PROSPERO (CRD42023390300). The search was performed in MEDLINE (PubMED), Cochrane Library, CINAHL and Web of Science (WOS) databases from inception to 31st December 2022 using the terms "cancer", "head and neck neoplasms", "exercise", "rehabilitation", "complications", "muscle contraction", "muscle stretching exercises" combining with booleans "AND"/"OR". PEDro scale, Cochrane Risk of Bias Tool and GRADE were used to assess methodological quality, risk of bias and grade of recommendation of included studies respectively. 18 studies (n = 1322) were finally included which 1039 (78.6%) were men and 283 (21.4%) were women. In patients who underwent radio-chemotherapy, overall pain [SMD = - 0.62 [- 4.07, 2.83] CI 95%, Z = 0.35, p = 0.72] and OP [SMD = - 0.07 [- 0.62, 0.48] CI 95%, Z = 0.25, p = 0.81] were slightly reduced with exercise in comparison to controls. Besides, lower limb muscle strength [SMD = - 0.10 [- 1.52, 1.32] CI 95%, Z = 0.14, p = 0.89] and fatigue [SMD = - 0.51 [- 0.97, - 0.057] CI 95%, Z = 2.15, p < 0.01] were also improved in those who receive radio-chemoradiation. In HNC survivors treated with neck dissection surgery, exercise was superior to controls in overall pain [SMD = - 1.04 [- 3.31, 1.23] CI 95%, Z = 0.90, p = 0.37] and, in mid-term, on shoulder pain SMD = - 2.81 [- 7.06, 1.43] CI 95%, Z = 1.76, p = 0.08]. No differences in quality of life were found at any of the follow-up periods. There is evidence of fair to good methodological quality, low to moderate risk of bias, and weak recommendations supporting the use of exercise-based rehabilitation to increase functionality. However, no evidence was found in favor of the use of this modality for improving the quality of life of HNC survivors who underwent chemoradiotherapy or surgery.

Scientific Research Directions on the Histopathology and Immunohistochemistry of the Cutaneous Squamous Cell Carcinoma: A Scientometric Study. Medicina (B Aires) 2022; 58:medicina58101449. [PMID: 36295609 PMCID: PMC9611311 DOI: 10.3390/medicina58101449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/08/2022] [Accepted: 10/12/2022] [Indexed: 11/21/2022] Open
Abstract
Introduction: Cutaneous squamous cell carcinoma (cSCC) is one of the most frequently occurring types of cancer in humans. Scientometric research is an innovative method for analyzing the research trends in various domains, with great implications in the field of medicine. Materials and Methods: We searched the Web of Science database with the following established query terms: “Squamous cell carcinoma”, “skin”, and “immunohistochemistry”. After applying the inclusion and exclusion criteria, a total of 76 articles were selected. The present study aims to analyze, based on the frequency of use of keywords with scientometric algorithms and map-based distributions, the trends of the research concerning cSCCs in 2017–2022. Results: A graphical representation based on 11 scientometric maps presented the division of the keywords into seven clusters, from which seven categories of research interest were defined. The clusters represent a multidisciplinary approach to the diagnosis and treatment of cSCCs, cancer diagnostics, patient outcomes, histopathological importance, management of cSCCs, role of progression, and adequate treatment of and importance of immunohistochemistry for cSCCs. The distribution of the citations shows the importance of the available research on cSCCs by analyzing the first five most-cited articles included in our study in direct concordance with the seven defined clusters. Conclusion: The scientometric research method reveals the interest of research in the multidisciplinary approach used to obtain the best outcomes for the patient, including a targeted investigation, as well as diagnostic and treatment options. The trends in the research reveal that histopathological diagnostics and immunohistochemistry, combined with molecular techniques, are the most important tools used to establish a personalized diagnosis, thus increasing the quality of life and life expectancy for patients with cSCCs.

Abstract
Lymphoepithelioma-like carcinoma (LELC) of the conjunctiva is a rare malignancy in the ocular adnexa. There are no prospective data regarding treatment methods. Complete surgical excision is sufficient in the majority of cases. Radiation therapy is sometimes used in case of recurrence or positive margins after surgery. This case describes an 89-year-old Hispanic female with a 7-month history tumor primarily located on the left lower palpebral conjunctiva. The patient underwent an excisional biopsy of the tumor, and histopathology exam reported an LELC with positive margins. She developed parotid and neck lymph node metastasis treated with concurrent radiotherapy. The patient had remained disease-free for 3 years. According to the available data, there are only five cases of LELC reported in conjunctiva worldwide, so this report increases the differential diagnoses of tumors in the ocular adnexa and supports the effectiveness of radiotherapy.

Abstract
Thymic lymphoepithelial carcinoma (TLEC) is a primary thymic carcinoma that accounts for about 14% of all thymic epithelial tumors and is classified into 14 types. The histological morphology is similar to lymphoepithelioma, a type of undifferentiated nasopharyngeal carcinoma. It has been reported that squamous carcinoma accounts for approximately 80% of thymic carcinoma, followed by TLEC, which accounts for 6%. TLEC has been reported to be associated with Epstein-Barr virus (EBV), with EBV infection in TLEC tumor cells first noted by Lyvraz et al. in 1985. Tumors shown to be EBV-positive are classified as TLEC if lymphoplasmacytic infiltration is lacking. However, only about 50% of the cases are positive for EBV, which is lower compared to nasopharyngeal lymphoepithelioma. Instances of EBV infection in other types of thymic epithelial tumor have been reported at lower rates, which suggests that EBV infection may have an important influence on the carcinogenesis of TLEC, though the etiology is unknown. TLEC is a highly malignant tumor with poor prognosis, as affected patients have a median survival time of 22 months, according to 58 cases from the literature, while the 5-year survival rate is 34.4%. Presently, prognosis is not considered to be affected by the presence or absence of EBV positivity.

Abstract
AIM Lymphoepithelioma-like carcinoma (LELC) is a rare histological types of solid tumors. The present study aims to comprehensively describe the demographic and clinical features of LELC using surveillance, epidemiology, and end results (SEER) database, with an emphasis on the prognostic difference according to primary tumor sites of LELC. MATERIALS AND METHODS A population cohort with histologically diagnosed LELC were identified from SEER database between 1973 and 2016. Age-adjusted incidence rates and cancer-specific survival (CSS) were determined. Cox-regression proportional hazards model was used for both univariate and multivariate analyses. RESULTS In total, 2106 patients with LELC were identified, with the most common diagnosed primary tumor site of nasopharyngeal LELC (56.22%), followed by non-nasopharyngeal head and neck LELC (21.32%) and respiratory system (7.83%). The overall age-adjusted incidence of LELC was 0.091 per 100,000. The CSS rates of LELC patients at 5, 10, 15, and 20 years were 76%, 69%, 65%, and 61%, respectively. A tendency of decreasing incidence of LELC was observed in the past decade. Univariate analysis indicated that sex [hazard ratio (HR) 1.21, p = 0.031], year of diagnosis (HR 0.60 and 0.63, p < 0.001), race (HR 1.29, p = 0.0021), age (HR 1.25, p = 0.0072), summary tumor stage (HR 1.97, and 4.57, both p < 0.001), number of positive LN(HR2.21, p < 0.001), surgery (HR 0.58, p = 0.0033), chemotherapy (HR 1.19, p = 0.037) and primary tumor site (p < 0.001) were significant factors associated with prognosis of LELC. In multivariate analysis, age (HR 1.75, p = 0.03), distant stage (HR 6.57, p = 0.0001), number of positive LN (HR 2.63, p = 0.0015) and non-nasopharyngeal head and neck LELC (HR 0.37, p = 0.0031) were significantly independent predictors for CSS of LELC. In sub-group analysis, radiotherapy significantly improves CSS for nasopharyngeal LELC (HR 0.57, p = 0.0002), while surgery significantly improve CSS for non-nasopharyngeal LELC (HR 0.33, p < 0.0001). CONCLUSION Based on SEER data analysis, age older than 50 years, distant stage and more than three positive LN are significantly associated with worse CSS for LELC, while the prognosis of non-nasopharyngeal head and neck LELC is significantly better than nasopharyngeal LELC. Local treatments for LELC could be recommended according to primary tumor sites.

Abstract
RATIONALE Pulmonary lymphoepithelioma-like carcinoma (PLELC) is a rare type of primary malignant lung tumor characterized by Epstein-Barr virus infection, with, to the authors' knowledge, a total of only 500 reported cases during the past 30 years worldwide. Histologically, PLELC is similar to undifferentiated nasopharyngeal carcinoma and poorly differentiated squamous cell carcinoma. However, although PLELC accounts for <1% of all lung cancers, it has a better prognosis and is usually detected in non-smokers and individuals of Asian ancestry. PATIENT CONCERNS The patient presented with chest distress of no apparent cause, dizziness, headaches, and a feeling of disequilibrium without remission, as well as a pulmonary nodule incidentally detected on contrast-enhanced computed tomography (CT). DIAGNOSIS PLELC was confirmed histopathologically rather than on preoperative CT; nevertheless, CT findings still contributed to the diagnosis. INTERVENTIONS The patient underwent thoracoscopic wedge resection of the affected lung. OUTCOMES The patient recovered after the lung nodule was completely removed, and was discharged. No evidence of recurrence or metastasis was found at the latest follow-up appointment 2 months after the operation. LESSONS PLELC is a rare bronchogenic carcinoma associated with lymphatic tissue with a favorable prognosis in most cases. With nonspecific clinical symptoms, specific radiological findings may facilitate an early diagnosis in some cases, followed by timely surgical intervention.
