RESUMEN
OBJECTIVE: Several scoring systems have been developed to predict prognosis in patients with refractory cancer. We aimed to validate eight scoring systems and determine the best method for predicting the prognosis of head and neck squamous cell carcinoma treated with nivolumab. METHODS: This multicentre retrospective study involved 154 patients with recurrent and/or metastatic head and neck squamous cell carcinoma treated with nivolumab between 2017 and 2020. Oncological outcomes were assessed according to the scoring systems, including MD Anderson Cancer Center + neutrophil-to-lymphocyte ratio and Hammersmith scores. Objective response, overall survival and progression-free survival were evaluated using logistic regression and Cox proportional hazards analyses. Receiver operating curve analysis was used to calculate the area under the curve and estimate the efficacy of each score. RESULTS: No significant associations were found between the responses and any score. Seven of the eight scoring systems were associated with disease control (odds ratio, 0.26-0.70). Amongst the eight scoring systems, MD Anderson Cancer Center + neutrophil-to-lymphocyte ratio showed the highest area under the curve for predicting response and disease control. Seven scoring systems were prognostic factors for progression-free survival (hazard ratio, 1.22-1.95). All eight scoring systems were prognostic factors for overall survival (hazard ratio, 1.62-3.83). According to the time-dependent receiver operating characteristics analysis for overall survival, the Hammersmith scoring system had the best predictive ability at 3 months, and the MD Anderson Cancer Center + neutrophil-to-lymphocyte ratio scoring system had the highest area under the curve between 6 and 24 months. CONCLUSIONS: MD Anderson Cancer Center + neutrophil-to-lymphocyte ratio and Hammersmith scoring systems were better predictors of prognosis in patients with head and neck squamous cell carcinoma treated with nivolumab.

This report details two cases of right upper-lobe lung cancer, of patients aged 62 and 56 years, requiring complex bronchoplasty and thoracoscopic surgeries. In both cases, owing to intraoperative complications, extended thoracotomies were performed to gain access to the right main pulmonary artery. The postoperative courses were uneventful, implying that this approach was safe. Uncomplicated postoperative recoveries underscore the need for adaptable surgical techniques, especially when traditional positioning fails. It emphasizes extending thoracotomy incisions for safer hilar structure access, offering insights for handling similar complex surgeries where standard methods falter.
RESUMEN
The frequency of metastasis to the pancreas is limited, and the frequency of metastasis of a squamous cell carcinoma of the esophagus is limited even further. The curative resection of this type of metastatic lesion has been reported for some patients; however, the survival benefit that can be attributed to these procedures has not yet been clearly determined. The patient examined in the present study was a 54-year-old man who was diagnosed with a lower thoracic esophageal cancer. Computed tomography revealed a 2-cm tumor at the tail of the pancreas. Since no other obvious distal metastases were observed, the patient underwent simultaneous surgical procedures, excising the esophageal squamous cell carcinoma and the pancreatic metastasis. A histopathological examination confirmed squamous cell carcinoma in both specimens. The patient has been free of disease for 9 months since the resection. A literature review of all relevant cases to date also demonstrated that the primary tumor site in all cases of patients with esophageal cancer presenting with metastasis to the pancreas was the lower thoracic esophagus. Complete simultaneous resections of esophageal squamous cell carcinoma and a solitary metastasis to the pancreas is beneficial and may produce favorable outcomes. However, due to the reduced number of corresponding reports, further studies are required for the confirmation of the benefits of surgery.
