ABSTRACT

Objective: Retrospectively analyzed the esophageal carcinoma (EC) patients with esophageal perforation (EP) after radiotherapy to discuss the treatment and prognosis. Methods: Data of patients with EC who had EP after radiotherapy in Hebei Cancer Hospital were collected from 2001 to 2020 and retrospectively analyzed. All analyses were performed using SPSS Statistics for Windows, version 18. 0 (SPSS Inc., Chicago, Ill., USA). P values less than 0.05 were considered statistically significant. Results: A total of 94 patients with EC were enrolled, among which 72 were males and 22 were females, with a median age of 62 (38-82) years. The tumor was located in the upper thoracic in 45 patients, middle thoracic in 45 patients, and lower thoracic in 4 patients. There were 30 cases of tracheoesophageal fistula (TEF) and 64 cases of esophagomediastinal fistula (EMF). All patients died within 11 months (median: two months) after EP. After EP, 48 patients were treated by tube feeding (include nasal feeding and gastrostomy), 26 patients by esophageal stenting, and 20 patients by fluid infusion therapy, and their one, three, and six months survival rates after EP were 81.3%, 31.3%, and 12.5% (P = 0.000). In the TEF group, the one, three, and six month survival rates after EP of tube feeding, esophageal stenting and fluid infusion groups were 88.2%, 17.6%, 11.8%; 45.5%, 27.3%, 0%; and 50.0%, 50.0%, 0% (P = 0.345). In the EMF group, the one, three, and six months survival rates after EP of this three groups were 77.4%, 38.7%, 12.9%; 26.7%, 20.0%, 6.7%; and 22.2%, 11.1%, 0% (P=0.002), respectively. Conclusion: Most patients with EP after radiotherapy died within six months, with low survival and poor prognosis. Tube feeding therapy can achieve relatively good survival, especially for patients with EMF. The survival of patients treated by tube feeding therapy is significantly better than the survival of those treated by other methods.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Research has confirmed that transforming growth factor-beta1 (TGF-beta1) is one of the cytokines related to radiation pneumonitis. But the level of TGF-beta1 in serum needed to predict radiation pneumonitis is still not clear. This study assessed the value of TGF-beta1 in both serum and induced sputum in predicting radiation pneumonitis, providing a reference for the radiotherapy of patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>A total of 23 patients with NSCLC treated with three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiation therapy (IMRT) in our department between November 2007 and January 2009 were analyzed and evaluated. TGF-beta1 levels in both serum and sputum were detected before and near the end of radiotherapy for all the patients. The TGF-beta1 level in serum was measured with enzyme-linked immunosorbent assay (ELISA). Immunocytochemistry assays were used to detect TGF-beta1 expression in sputum sediment. Radiation pneumonitis was graded according to Radiation Therapy Oncology Group (RTOG) radiation scoring criteria every 3 weeks from the start to 3 months after the end of treatment.</p><p><b>RESULTS</b>Radiation pneumonitis was noted in 9 patients in this cohort. The total incidence of radiation pneumonitis was 39.1% (9/23) and those with Grade II or worse was 30.4% (7/23). The absolute TGF-beta1 level in serum after radiotherapy was higher than before radiotherapy, but there was no statistical difference (P = 0.139). Patients with increased levels of TGF-beta1 had a higher incidence of radiation pneumonitis (45.5%) than those with decreased TGF-beta1 levels post-radiotherapy (40.0%). Though there was a tendency of higher incidence of radiation pneumonitis with increases in TGF-beta1 level, no statistical difference was found (P = 1.000). Patients with tumor response had higher incidence of radiation pneumonitis (50.0%) than patients without when TGF-beta1 levels in serum increased, but there was no statistical difference (P = 0.792). TGF-beta1 was positively expressed (brown yellow) in sputum on immunocytochemistry assays and located in the cytoplasm of either macrophages or epithelial cells. Macrophages were the main cells expressing TGF-beta1. A significantly higher positive expression rate (71.4%) was found in sputum post-radiotherapy than pre-radiotherapy (28.6%) (P = 0.015). The higher incidence of radiation pneumonitis (46.7%) was found in patients with positive TGF-beta1 expression in sputum post-radiotherapy than those with negative expression post-radiotherapy (14.3%) (P = 0.193).</p><p><b>CONCLUSION</b>It may be more reasonable to predict radiation pneumonitis by combining the change of TGF-beta1 levels in serum with tumor response than just the change of TGF-beta1 levels in serum alone. TGF-beta1 can positively express in the sputum of patients with NSCLC, located in macrophages and epithelial cells, with macrophages as the main areas of expression. Patients with positively expressed TGF-beta1 in sputum after radiotherapy have a higher incidence of radiation pneumonitis than those with negative expressions. The positive expression of TGF-beta1 in sputum is expected to become a factor for predicting radiation pneumonitis.</p>

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>The role of adjuvant radiotherapy to the regional nodes in women with T1 to T2 breast cancer and one to three positive nodes is controversial. This study compared and analyzed the prognosis of patients with T1-T2 breast cancer with one to three positive nodes after modified radical mastectomy with or without postoperative radiotherapy.</p><p><b>METHODS</b>The cases of 434 women patients with T1 to T2 breast cancer with one to three positive lymph nodes after modified radical mastectomy were reviewed, of which 196 patients received postoperative radiotherapy and 238 patients did not. The ipsilateral chest wall and supraclavicular fossa were irradiated with doses of 46-50 Gy in 23-25 fractions.</p><p><b>RESULTS</b>For all patients, the 3- and 5-year rates of overall survival (OS) were 94.7% and 85.7% respectively, local control (LC) 96.5% and 95.6%;, and disease-free survival (DFS) 89.3% and 82.3% respectively. The 3- and 5-year OS rates for patients without radiotherapy were 92.7% and 97.1% and for those with radiotherapy were 82.4% and 89.2%, both with significant differences (P = 0.039). The 3- and 5-year LC rates for patients without radiotherapy were 94.8% and 98.4% and for those with radiotherapy were 93.6% and 97.7%, again with significant differences (P = 0.041). The 3- and 5-year DFS rates for patients without radiotherapy were 87.8% and 91.3% and for patients with radiotherapy were 78.5% vs 86.1% (P = 0.047).</p><p><b>CONCLUSIONS</b>Postoperative radiotherapy confers better rates of OS, LC, and DFS in patients with T1 to T2 breast cancer with one to three positive nodes after modified radical mastectomy.</p>
