AI Article Synopsis
- The study examined lung cancer patient characteristics in Manaus, Brazil, analyzing data from 1995 to 2002.
- Most patients were male (74.4%), with a mean age of 62; squamous cell carcinoma was the most common type.
- A majority (73.4%) of patients received treatment, but survival rates were very low: 3-year survival was 6.5%, and 5-year survival was 3.5%.
- The findings suggest that poor survival may be linked to late-stage diagnosis and limited access to specialized healthcare.
Article Abstract
Objective: To analyze the characteristics of patients with lung cancer.
Methods: A retrospective descriptive study of patients receiving a histopathological diagnosis of lung cancer between 1995 and 2002 in the city of Manaus, Brazil. Data were collected from the medical archives of three hospitals. Statistical analyses were carried out, and survival curves were generated by means of an actuarial estimator.
Results: Of the 352 patients selected, 262 (74.4%) were male and 90 (25.6%) were female. The mean age was 62 years. The following histological types were identified: squamous cell carcinoma, 62.8%; adenocarcinoma, 24.7%; small cell carcinoma, 9.1%; and large cell carcinoma, 3.4%. The most common stages were stages IIIB and IV, in 45% and 21.5%, respectively. Of the total sample, 73.4% were submitted to treatment. Of these, 51.4% underwent radiotherapy; 16.6%, surgery; 15.8%, chemotherapy; and 16.2%, radiotherapy in association with chemotherapy. Cumulative survival rates were low: three-year survival was 6.5%, and five-year survival was 3.5%.
Conclusions: In this group of patients with lung cancer, survival rates were considerably lower than those reported in the literature. This might be attributable to the limited access to the specialized health care system and the advanced stage of the disease at diagnosis.

Clinical outcomes and cost-utility analysis of GKRS plus TKIs versus TKIs in patients with EGFR-mutant lung adenocarcinoma and brain metastases: a Markov decision model.

Objective: This study focuses on epidermal growth factor receptor-mutated lung adenocarcinoma, known for frequent brain metastasis. It aimed to compare the clinical outcomes and cost-effectiveness of combining Gamma Knife radiosurgery (GKRS) with tyrosine kinase inhibitors (TKIs) (GKRS+TKI group) versus TKIs alone (TKI group) for the treatment of patients with newly diagnosed brain metastasis in this condition.
Methods: Study characteristics of the two groups were matched using inverse probability of treatment weighting (IPTW).

Background: Existing risk evaluation tools underperform in predicting intensive care unit (ICU) admission for patients with the Coronavirus Disease 2019 (COVID-19). This study aimed to develop and evaluate an accurate and calculator-free clinical tool for predicting ICU admission at emergency room (ER) presentation.
Methods: Data from patients with COVID-19 in a nationwide German cohort (March 2020-January 2023) were analyzed.

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.

Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.
