Selection criteria for neoadjuvant chemoradiotherapy of rectal cancer : Neoadjuvant therapy even for locally advanced colon cancer?

[Selection criteria for neoadjuvant chemoradiotherapy of rectal cancer : Neoadjuvant therapy even for locally advanced colon cancer?] Chirurg. 2020 Jan 08;: Authors: Kastner C, Petritsch B, Kim M, Germer CT, Wiegering A 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 in UICC stages II and III with neoadjuvant therapy, independent of the height localization. In the meantime this has increasingly been relativized and only locally advanced tumors of the middle and lower thirds of the rectum should be pretreated, whereas tumors of the upper third of the rectum should basically be treated in the same way as colon cancer. It is to be expected that there will be further differentiation concerning the indications in this context in the future mainly based on a preoperative magnetic resonance imaging (MRI) examination. At the same time, initial studies for colon cancer show that neoadjuvant...

Abstract Objectives: We aimed to evaluate the possible role of dietray TAC against different types of cancers in a systematic review and meta-analyses of observational studies. Methods: A literature search of authentic electronic resources had been performed to obtain the relevant studies up to February 2020. Results: Twenty-one studies including nine prospective and twelve case-control studies were included in the current systematic review and meta-analysis. These studies have included 1404297 individuals. Higher TAC categories were associated with 21% reduced risk of colorectal cancer, 27% reduced risk of endome...

CONCLUSIONS: cRGD-ZW800-1 enabled fluorescence imaging of colon cancer in both open and minimal invasive surgeries. Further development of cRGD-ZW800-1 for widespread use in cancer surgery may be warranted given the ubiquitous overexpression of various integrins on different types of tumors and their vasculature.

DR DANIEL ALBO (Augusta, GA): There is a significant shift in the presentation of colorectal cancer in population-based studies. Currently, 3 of 10 rectal cancers are actually diagnosed before the age of 50 years. I noticed that you focused your study on colon cancer patients. Did you notice a significant number of these patients who present with rectal disease as a primary site, in particular, the carcinomatosis data set? Those are known to have an even more aggressive prognostic factor of outcomes.

CONCLUSIONS: Neuroendocrine marker-positive cells in colorectal cancer tissue are more common in the right sided colon, whereas neuroendocrine marker-positive cells in normal mucosa are more common in the rectum. These results suggest that NEC may arise from preceding adenocarcinomas. PMID: 31390635 [PubMed - as supplied by publisher]
