Purpose: To describe the characteristics and recurrence rates of primary periocular squamous cell carcinoma (SCC) in Spain. Methods: This retrospective study investigates the characteristics of primary periocular SCC at two tertiary centers in Spain from 2000 to 2020. Data were collected on demographics, skin phenotype, location, clinical and histological diagnosis, the commitment of surgical margins, recurrence, and risk factors. Multivariate analysis and risk factors were used to investigate recurrence rates, considering p < 0.05 as statistically significant. Results: Over the 20-year studied period, 107 patients with primary periocular SCC were assessed. The mean age of SCC was 76.8 ± 12.8 years, 55 (50.9%) were females, and 105 (98.1%) had Fitzpatrick skin phenotype type II or III. SCC lesions affected less than 1/3 of the eyelid (56/52.3% cases), mainly the lower lid (42/39.3% lesions). Sixty (56.1%) cases were SCC differentiated, 76 (71%) had clear margins. Clinical diagnosis of SCC corroborated with histological in 84 (78.5%) cases and orbital involvement occurred in 18 (16.8%) cases. Recurrence was observed in 13 (12.1%) cases, occurring more in large tumors and undifferentiated subtype (53.8%), with committed margins (69.2%) ( p = 0.001), being the commitment of margins a significant predictor for recurrence, although thickness was an independent predictor. Conclusion: Periocular SCC in Spain showed a similar pattern as in the world. The risk of recurrence is increased in undifferentiated and large periocular SCC, partially removed with committed margins.

INTRODUCTION: Esophageal cancer is one of the most common cancers in the world affecting males more often than females and with a poor prognosis. The aim of our work was to describe the epidemiology of patients followed for esophageal cancer at the Joliot-Curie Institute in 2018. MATERIALS AND METHODS: This is a descriptive retrospective study including all patients followed at the institute from January 1, 2018 to December 31, 2018 for esophageal cancer with histological evidence. RESULTS: We collected 93 patients referred to the institute for the management of esophageal cancer, 46 women (49.5%) and 47 men (50.5%). The mean age was 49 years with a median age of 50 and extremes of 22 and 84 years. The notion of smoking was found in 24 patients (25.8%) exclusively men (51%), associated in six cases with a notion of alcoholism. The median consultation time was five months. The main circumstance of discovery remains dysphagia (87.1%), followed by aphagia (4.3%) and odynophagia (4.3%). Squamous cell carcinoma is the most represented histological type with 89 patients (95.7%) distributed as follows: 45 women and 44 men. Adenocarcinoma was found in three cases (two men and one woman) and finally one case of adenosquamous carcinoma. CONCLUSION: Squamous cell carcinoma is the most frequent esophagus cancer. It represents the fifth location in our institute and occurs in young patients without gender predominance.

The Mean

Pteridium arachnoideum, a fern of the Pteridium aquilinum species complex found in South America, is responsible for several different syndromes of poisoning. Cases of bovine enzootic hematuria and upper alimentary squamous cell carcinoma are both frequent occurrences in Brazil, whereas only bovine enzootic hematuria is noted with any frequency around the world. The reason for the high frequency of upper alimentary squamous cell carcinoma in Brazil is not currently known. One possible explanation may be the higher levels of ptaquiloside and pterosin B in Brazilian Pteridium than those present in the plant in other countries. However, these levels have not yet been determined in P. arachnoideum. Thus, the present study aimed to measure and compare ptaquiloside and pterosin B levels in mature green fronds and sprouts of P. arachnoideum collected from different locations in Brazil. Samples of P. arachnoideum were collected from the states of Minas Gerais and Rio Grande do Sul. A total of 28 mature leaf samples and 23 sprout samples were used. The mean concentrations of ptaquiloside and pterosin B present in the mature green fronds of P. arachnoideum ranged from 2.49 to 2.75 mg/g and 0.68 to 0.88 mg/g, respectively; in P. arachnoideum sprouts, mean concentrations of ptaquiloside and pterosin B ranged from 12.47 to 18.81 mg/g, and 4.03 to 10.42 mg/g for ptaquiloside and pterosin B, respectively. Thus, ptaquiloside and pterosin B levels in P. arachnoideum samples collected in Brazil were higher in sprouts than in mature green fronds, as observed in other countries. However, there was no variation in ptaquiloside levels among plants collected from different cities in Brazil. The high frequency of upper alimentary squamous cell carcinoma in Brazilian cattle may not be attributed to greater levels of ptaquiloside and pterosin B in P. arachnoideum than in other Pteridium species in other countries.

Rare Malignancy

Leiomyosarcoma (LMS) of the trachea is an extremely rare malignancy with only a few reported cases in English literature. As such the diagnosis can be frequently missed or delayed. We present a case of a 69-year-old male who underwent tracheostomy for airway obstruction secondary to glottic squamous cell carcinoma and treated definitely with radiation therapy. Subsequently, the patient developed LMS of the tracheostomy site. The case further details multiple risk factors that could contribute to development of LMS including radiation exposure, prior malignancy, and chronic inflammation. These risk factors have been well established for LMS in other sites but less so in the head and neck region, which is the subject of our discussion. We also review the current guidelines for head and neck as well as limb sarcomas and discussed role of surgery or radiation and their accompanying challenges in management of this rare malignancy.

Abstract Background A nomogram was developed to predict lymph node metastasis (LNM) for patients with early-stage esophageal squamous cell carcinoma (ESCC). Methods We used the clinical data of ESCC patients with pathological T1 stage disease who underwent surgery from January 2011 to June 2018 to develop a nomogram model. Multivariable logistic regression was used to confirm the risk factors for variable selection. The risk of LNM was stratified based on the nomogram model. The nomogram was validated by an independent cohort which included early ESCC patients underwent esophagectomy between July 2018 and December 2019. Results Of the 223 patients, 36 (16.1%) patients had LNM. The following three variables were confirmed as LNM risk factors and were included in the nomogram model: tumor differentiation (odds ratio [OR] = 3.776, 95% confidence interval [CI] 1.515–9.360, p = 0.004), depth of tumor invasion (OR = 3.124, 95% CI 1.146–8.511, p = 0.026), and tumor size (OR = 2.420, 95% CI 1.070–5.473, p = 0.034). The C-index was 0.810 (95% CI 0.742–0.895) in the derivation cohort (223 patients) and 0.830 (95% CI 0.763–0.902) in the validation cohort (80 patients). Conclusions A validated nomogram can predict the risk of LNM via risk stratification. It could be used to assist in the decision-making process to determine which patients should undergo esophagectomy and for which patients with a low risk of LNM, curative endoscopic resection would be sufficient.

AbstractThe control of distant metastasis in oral squamous cell carcinoma is an important determinant of improved prognosis. The study aimed to identify risk factors for distant metastasis in patients with locoregionally controlled oral carcinoma. We identified 982 patients with oral squamous cell carcinoma treated at our hospital between January 2008 and December 2017. After excluding patients with distant metastasis at initial treatment, patients with metastasis to the oral cavity, those receiving palliative treatment, and those lacking follow-up data, 941 patients were selected. Finally, among these 941 patients, 887 with locoregionally controlled oral squamous cell carcinoma were included in the study. Among the 887 patients, 36 had confirmed distant metastasis (4.1%), and the lung was the most common site (31/36 patients, 86.1%). Multivariate analysis showed that the incidence of primary intraosseous carcinoma of the mandible, cervical lymph node metastasis at levels IV and V, and the presence of pathological extranodal extension were significant risk factors for distant metastasis. When treating patients with oral squamous cell carcinoma who are positive for the aforementioned risk factors, the possibility of developing distant metastases must be accounted for, and aggressive treatment should be planned accordingly.
