Therefore, the capabilities of F-18-Fluorodesoxyglucose-PET in comparison to histomorphological grading of tumor regression were studied. Methods: In 33 patients with locally advanced esophageal carcinoma (uT3, uN0-1, cM0) F-18-FDG-PET was performed before and 2 weeks after radiochemotherapy. All tumors were resected by transthoracic en-bloc esophagectomy 3–4 weeks after induction therapy. A subgroup of 11 patients underwent weekly PET scan during neoadjuvant therapy. PET was performed in a dedicated scanner 1.3 h after administration of 370 MBq F-18-FDG. Data analysis based on maximum SUV data derived from individual regions of interest in pre- and posttherapeutic images. PET data were compared to histomorphological grading parameters for tumor regression whithin the resected tissues. Results: The comparison of histopathological tumor regression after neoadjuvant therapy and PET SUV di?erences showed a signi?cant χ2 P -value of 0.006. There was a signi?cant decrease 五笔字型计算机汉字输入技术 of the SUV data from 9.1±3.5 to 4.3±1.9 (P <0.0001). In therapy responders SUV was diminished by 59 % and in non-responders by 34 %. Longitudinal SUV measurement during neoadjuvant therapy showed a strong SUV decrease already after one and two weeks (P =0.021 and 0.003). Conclusion: The recent data of the FDG-PET follow-up after neoadjuvant therapy show that PET is able to predict therapy response. Longitudinal PET data advocate that it may be possible to recognize response also very early during radiochemotherapy.展开更多

The TME is highly dynamic and its importance in different stages of cancer progression has been well recognized. A growing body of evidence suggests that TME also plays pivotal roles in cancer treatment responses. TME is significantly remodeled upon cancer therapies, and such change either enhances the responses or induces drug resistance. Given the importance of TME in tumor progression and therapy resistance, strategies that remodel TME to improve therapeutic responses are under developing. In this review, we provide an overview of the essential components in TME and the remodeling of TME in response to anti-cancer treatments. We also summarize the strategies that aim to enhance therapeutic efficacy by modulating TME.展开更多
