Background: Long-term survival outcomes are crucial for accurately determining the effectiveness of treatment in an indolent disease like thymoma. We aimed to analyze the clinical findings in terms of survival and relapse patterns with a median follow up of 105 months (8.7 years) in patients with thymoma and myasthenia gravis who underwent minimally invasive surgery between 2002 and 2015., Methods: A total of 59 pathologically confirmed Masaoka Stage I and II thymoma patients with Myasthenia Gravis (MG) who underwent minimally invasive thymoma resection were included in this study. Primary aim of this study is to evaluate recurrences, overall and disease free survival in patients with a thymoma and MG in the long run. We also aimed to study the changes in Myasthenia Gravis medication during the follow-up., Results: The mean age of the patients was 47.6 +/13.5 years. Seventeen patients were at Masaoka Stage I and 42 were at Masaoka Stage II. The median follow-up time was 105 months. The mean size of the tumor was 3.6 cm +/16.2 cm. Twenty-one patients (35%) received adjuvant radiotherapy. There was no postoperative mortality and median length of hospital stay was 4 days. Two patients developed recurrences both presented with pleural metastases. Eight patients died because of non-oncologic pathologies. 10-year disease free survival and overall survival rates were calculated to 96.6% and 86.4% respectively., Conclusion: The 10-year survival analysis and current myasthenic status of stage I-II thymoma patients with myasthenia gravis who underwent minimally invasive surgery demonstrate that these procedures are both safe and effective., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Kaba, Özkan, Kakuturu, Yardımcı, Erdoğdu, Çimenoğlu, Duman and Toker.)

Background: In this study, we aimed to investigate the prognostic effect of lymph node dissection in secondary lung tumor metastasectomies., Methods: Between January 2001 and December 2015, a total of 201 patients (122 males, 79 females; mean age: of 41.4±19.2 years; range, 3 to 79 years) who had pulmonary metastasectomy due to colorectal carcinoma, renal cell carcinoma, and soft tissue - skeletal sarcomas were retrospectively analyzed. The clinicopathological features of the patients, overall survival, and complication rates according to the presence of lymph node dissection were evaluated., Results: The most common histopathological subtype was a sarcoma in 118 (58.7%) patients, followed by colorectal carcinoma in 63 (31.3%) patients, and renal cell carcinoma in 20 (10%) patients. A total of 88 (43.7%) patients underwent systematic lymph node dissection with pulmonary metastasectomy. The mean overall survival of patients with and without lymph node dissection were 49±5.9 (95% confidence interval 37.3-60.6) and 26±4.4 (95% confidence interval 17.2-34.7) months, respectively (p=0.003). The five-year survival rates in colorectal carcinoma, renal cell carcinoma, and sarcoma were 52%, 30%, and 23%, respectively (p=0.002). Locoregional recurrences occurred in 15 (35.7%) patients in the lymph node dissection group and in 23 (60.5%) patients in the non-lymph node dissection group (p=0.026). Lymph node dissection did not show a significant relationship regarding to postoperative complications (p=0.09)., Conclusion: Lymph node dissection following pulmonary metastasectomy may improve the overall survival and reduce locoregional recurrence, without any increase in morbidity and mortality., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2022, Turkish Society of Cardiovascular Surgery.)

Background: Pulmonary sarcomatoid carcinomas are very rare lung neoplasms, and no consensus exists regarding their optimal treatment. The prognosis of sarcomatoid carcinomas has been reported to be unfavorable compared with non-small-cell lung cancers; however, prognostic factors in patients undergoing surgery for sarcomatoid carcinomas remain unclear., Aims: To analyze clinicopathologic prognostic factors and survival outcomes in patients who underwent surgery for pulmonary sarcomatoid carcinoma., Study Design: Retrospective cross-sectional study., Methods: We designed a retrospective cross-sectional study in patients who underwent surgery for pulmonary sarcomatoid carcinomas and statistically analyzed the prognostic factors regarding clinicopathologic features with respect to survival outcomes., Results: We had a total of 44 patients with sarcomatoid carcinoma who had pulmonary resection. Sex distribution was 34 (77%) males and 10 (22.7%) females, which was determined by declaration. The mean age of patients was 57.3 ± 16 years with a median of 60 years. The 5-year progression-free survival and overall survival rates were 59% and 58%, respectively. The 5-year survival rates were significantly different for tumors > 5 cm (P = 0.044), tumorstatus (T) (P=0.016), lymph node status (N) (P=0.005), and pathologic tumor-node-metastasis (TNM) stage (P = 0.0001 ). However, histologic subtype (P = 0.628) and adjuvant treatment (P = 0.804) did not have any significant effect on survival. Similarly, the significant prognostic factors in univariate analysis were tumor size (P = 0.085), T status (P = 0.005), N status (P = 0.028), and pathologic TNM stage (P = 0.0001). Multivariate analysis showed only T status (P = 0.058), N status (P = 0.018), and pathologic TNM stage (P = 0.019) as independent prognostic factors, with statistical power of 87%, 43.1% and 21.2%., Conclusion: Surgery appears to be an optimal treatment with favorable outcomes for patients with pulmonary sarcomatoid carcinoma. Patients with small tumors at earlier stages are very likely to benefit from surgery, regardless of histologic subtype.
