OBJECTIVES: Craniofacial resection (CFR) procedures for craniofacial tumors with cranial extension are often extensive. Although CFRs may yield good oncological results, there are concerns about high perioperative morbidity and mortality. This study aimed to determine risk factors for perioperative mortality after open CFR in terms of deaths occurring during index hospitalizations. METHODS: We conducted a retrospective analysis of CFRs conducted at a tertiary oncology hospital from May 2009 through December 2018. RESULTS: Our analysis included data from the medical records of 102 patients, the majority of whom were male (n=74, 72.5%). The mean age was 61 years (±18.3 years). Skin malignancies (n=64, 63.4%) accounted for nearly two-thirds of the treated tumors, and most of these were squamous cell carcinoma. Postoperative medical complications occurred in 33 patients (33%), and surgical complications occurred in 48 (47%). Multivariate analysis revealed the only independent risk factors for perioperative deaths to be the presence of intracranial tumor extension on preoperative imaging (hazard ratio [HR]=4.56; 95% confidence interval [CI]: 1.74-11.97; p=0.002) and the unexpected emergence of postoperative neurological dysfunction (HR=10.9; 95% CI: 2.21-54.3; p=0.003). CONCLUSIONS: In our study, factors related to tumor extension were associated with a higher risk of perioperative death.

ABSTRACT Objective The present study describes the clinical and tumor characteristics of patients that died from differentiated thyroid cancer and reports on the cause and circumstances of death in these cases. Subjects and methods Retrospective analysis of all the differentiated thyroid cancer (DTC) related deaths at a single institution over a 5-year period, with a total of 33 patients. Results Most of the patients were female (63.6%), with a mean age at diagnosis of 58.2 years. The most common histologic type was papillary (66.7%) and 30.3% were follicular. The distribution according to the TNM classification was: 15.4% of T1; 7.7% T2; 38.4% T3; 19.2% of T4a and 19.2% of T4b. Forty-four percent of cases were N0; 20% N1a and 36.6% of N1b. Twelve patients were considered non-responsive to radioiodine. Only one of the patients did not have distant metastases. The most common metastatic site was the lung in 69.7%. The majority of deaths were due to pulmonary complications related to lung metastases (17 patients, 51.5%), followed by post-operative complications in 5 cases, neurological disease progression in 3 cases, local invasion and airway obstruction in one patient. Median survival between diagnosis and death was reached in 49 months while between disease progression and death it was at 22 months. Conclusion Mortality from DTC is extremely rare but persists, and the main causes of death derive from distant metastasis, especially respiratory failure due to lung metastasis. Once disease progression is established, median survival was only 22 months.

ABSTRACT Objective The aim of the present study was to describe the epidemiologic data, histological type, treatment and follow-up of the 811 patients treated for thyroid cancer in Instituto do Câncer do Estado de São Paulo (ICESP) over 5 years. Materials and methods Retrospective analyses of electronic chart information. Results There were 679 cases (83.7%) of papillary thyroid cancer, 61 (7.5%) of follicular carcinoma, 54 (6.7%) of medullary carcinoma, 11 (1.4%) of poorly differentiated carcinoma and 6 of anaplastic carcinoma (0.7%). The majority of patients were female (82.2%), and the mean age was 50.5 ± 15 years. Two hundred forty-two patients had disease persistence or recurrence. At the last follow-up, 629 (77.6%) patients were alive and disease free, 141 (17.4%) were alive with disease, and 41 (5.1%) were deceased, with 37 deaths related to thyroid cancer. Conclusion This study was able to outline the profile, disease type and evolution of patients treated for thyroid cancer at a single tertiary hospital.
