Abstract During the last two decades a neoadjuvant treatment concept has been established for an increasing number of malignant tumors of the gastrointestinal tract; however, these concepts are still subject to a constant change concerning the indications and type of treatment. A prime example for this is rectal cancer. The rate of local recurrence in particular was significantly reduced by neoadjuvant therapy but until now it has not been possible to validly show an improvement in overall or disease-free survival. At the beginning of the millennium it was recommended to treat every rectal carcinoma...

Abstract BACKGROUND: Hybrid imaging FDG PET/CT (18F‑fluordeoxyglucose positron emission tomography/computed tomography) has gained increasing importance in oncology in recent years. DIAGNOSIS: A focal increase in FDG uptake in the gastrointestinal tract may be due to colorectal carcinoma. Such a finding requires further clarification. PRIMARY STAGING: Staging of the primary and locoregional lymph nodes remains a domain of established imaging modalities as FDG PET/CT does not provide a clear additional benefit. Liver metastases can be detected with high sensitivity by FDG PET/CT, but...

Conclusions: This meta-analysis demonstrated that CD44 overexpression might be an unfavorable prognostic factor for CRC patients and could be used to predict poor differentiation, lymph node metastasis and distant metastasis. Introduction Although therapies for colorectal cancer (CRC) has improved in recent years, colorectal cancer is still the third most common cause of cancer related death worldwide (1). Metastasis are observed in 25% of patients at initial diagnosis and approximately 50% of patients will develop metastasis (2). Presently, the outcome prediction and the therapy schedule determination of CRC patie...

In this report, we are adding an extra finding, in which we show that the levels of circulating NRP-1 were significantly increased in patients who received NAC and had a partial response. Assessing patients who underwent NAC indicated that the levels of NRP-1 measured post-NAC were significantly higher in younger patients and patients with either a low or a medium body mass index (BMI), as well as in patients who remained with larger tumor size and partial response. Previously, we showed that SNAI1 expression in the immune cells collected from the peripheral blood of breast cancer patients was significantly higher in patie...

This study had a retrospective multicenter (two hospitals in China) design and a radiomic analysis was performed using contrast enhanced CT in advanced HGSOC (FIGO stage III or IV) patients. We used a minimum 18-month follow-up period for all patients (median 38.8 months, range 18.8–81.8 months). All patients were divided into three cohorts according to the timing of their surgery and hospital stay: training cohort (TC) and internal validation cohort (IVC) were from one hospital, and independent external validation cohort (IEVC) was from another hospital. A total of 620 3-D radiomic features were extracted and a Lass...

In this study, we examined the prognostic role of indoleamine-2,3-Dioxygenase (IDO1) and infiltrating cytotoxic T lymphocytes (CD8+) in locally advanced rectal carcinomas after neoadjuvant treatment. Expression of IDO1 and CD8 was evaluated by immunohistochemistry in 106 archival tumour tissue samples from patients following neoadjuvant chemoradiation and radical resection. The average infiltration of IDO1+  and CD8+ cells was calculated along the tumour invasive front, in the tumour centre and within the neoplastic cells and expressed as total scores. Of the tumour specimens evaluable for immunohistochemistr...
