ABSTRACT
Background: The clinical characteristics of patients who had lymph node-negative early breast cancer were assessed. Patients and Methods: We assessed a total of 576 patients in the study, including 74 patients (12.8%) with T1a, 119 patients (20.7%) T1b, and 367 patients (63.7%) with T1c. Patients with T1 tumors were further classified into three groups according to hormone receptor (HR) and human epidermal growth factor-receptor 2 (HER2) status. Results: In patients with T1a, the disease-free survival (DFS) rate was 98.4% at 2 years (P = 0.001). In subgroup analysis of early breast cancers, 10-year-DFS rates of the patients in HR+/HER2–, HR–/HER2+, and HR–/HER2– subgroups were not significantly different (P = 0.917). Conclusion: The T1a group had a worse prognosis than T1b and T1c groups in second years (P = 0.001); however, there was not statistically important difference between HR+, HER2+ and triple negative subgroups (P = 0.917). Although there are differences in patients and tumor features, the prognosis of patients with T1a, b, c N0M0 breast cancer is excellent
ABSTRACT
We report a rare case of synchronous presentation of nasopharyngeal and renal cell carcinomas in a-50-year old male patient with long standing smoking history. The patient was initially presented with a diagnosis of nasopharyngeal carcinoma. During staging process, the abdominal computed tomography detected a right renal solid mass, 6.5 cm in diameter, originating from posterior portion of the right renal cortex. Right radical nephrectomy was performed and pathological examination revealed renal cell carcinoma. Smoking was thought to be a risk factor for both cancers. Systemic evaluation of kidney should not be discarded in patients diagnosed with nasopharyngeal carcinoma living in western countries with a smoking history.
