Trends in Colorectal Cancer Surveillance: Current Strategies and Future Innovations-
AbstractPurpose of ReviewThis review article strives to reflect on the historic surveillance debate in colorectal cancer, outline current strategies, and guidelines, and discuss new techniques being explored in surveilling colorectal adenocarcinoma.Recent FindingsWithin the past decade, major governing bodies have proposed surveillance guidelines with the goal of earlier identification of cancer recurrence, thereby possibly reducing the morbidity and mortality of necessary interventions. With the innovation of tissue-specific tumor markers and fluorescence endoscopy, the approach to surveillance may be changing. The use of these new modalities allows clinicians to provide a more risk-adjusted basis for care, which is predicted to equate to higher quality care.SummaryThe current surveillance guidelines provide an evidence-based framework for physicians and surgeons to follow. However, the influence of these novel surveillance techniques in colorectal cancer is yet to be realized and they ultimately have the potential to revolutionize care.
ConclusionLaparoscopic surgery showed similar long-term results compared to open surgery in elderly patients with CRC. Laparoscopic surgery is an effective surgical procedure for elderly patients with CRC.Graphic Abstract
Conclusions: In the largest study to date of symptomatic individuals under 50 years of age undergoing colonoscopy in the USA, advanced CRN was most often detected in the distal colon and was associated with anemia, but not with abnormal bowel habits or abdominal pain. We also found that patients with CRN under 50 years of age were more likely to be male, smokers, and obese. These findings should prompt further investigation of these risk factors alone and in combination.
Colorectal cancers are generally recognized to develop from polyps. This “adenoma-adenocarcinoma sequence” theory has been in the mainstream of development of colorectal neoplasms. However, another theory was revealed, which is considered to emerge directly from normal epithelium, not through the adenomatous stage. This theory is called “de novo” pathway. Now, it is possible to presume the histology of colorectal lesions using magnifying endoscopy (×100 folds, pit pattern classification) and endocytoscopy (×520 folds, EC classification).
We present a 47-year-old woman with an MLH1 gene mutation (G133X 397G>T) who presented with menorrhagia. Eleven family members have this mutation, 6 with carcinoma: 5 colorectal and 1 with a gynecologic primary of unknown type. Colonoscopy and endoscopy were unremarkable. Positron emission and computed tomography revealed a 3 cm anterior dome bladder mass without additional extrauterine disease or uterine connection. She underwent partial cystectomy, laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. The uterus demonstrated a dedifferentiated endometrioid adenocarcinoma, immunohistochemical...
Endoscopy DOI: 10.1055/a-1104-5245In Europe at present, but also in 2040, 1 in 3 cancer-related deaths are expected to be caused by digestive cancers. Endoscopic technologies enable diagnosis, with relatively low invasiveness, of precancerous conditions and early cancers, thereby improving patient survival. Overall, endoscopy capacity must be adjusted to facilitate both effective screening programs and rigorous control of the quality assurance and surveillance systems required. 1 For average-risk populations, ESGE recommends the implementation of organized population-based screening programs for colorectal cancer, based...
Conclusions: The finding of advanced colonic neoplasia in follow-up colonoscopy after an acute episode of CT-proven diverticulitis is equivalent to, or less than, that of the population colorectal cancer screening program. Routine colonoscopy is not necessary unless there are other concerning symptoms/CT findings.
Abstract Endoscopy may be used for early screening of various cancers, such as nasopharyngeal cancer, esophageal adenocarcinoma, gastric cancer, colorectal cancer, and bladder cancer, and performing minimal invasive surgical procedures, such as laparoscopy surgery. During this procedure, an endoscope is used; it is a long, thin, rigid, or flexible tube having a light source and a camera at the tip, which facilitates visualization inside the affected organs on a screen and helps doctors in diagnosis.

Authors: Paulson B, Kim IH, Namgoong JM, Kim YG, Lee S, Moon Y, Shin DM, Choo MS, Kim JK Abstract Colorectal cancer (CRC) is one of the most frequently lethal forms of cancer. Intramucosal injection allows development of better mouse models of CRC, as orthotopic xenografts allow development of adenocarcinoma in the submucosa of the mouse colon wall. In this paper, a method of orthotopic injection is monitored longitudinally using cellular-resolution real-time in vivo fluorescence microendoscopy, following the injection of three different cell lines: 3T3-GFP to confirm immunosuppression and HCT116-RFP cells to model...
ConclusionThe fusion fascia of Fredet is useful to achieve CME and D3-L in right colon cancers with reduced risk of intraoperative complications. This structure is particularly suitable for minimally invasive surgery; therefore, we encourage awareness of the fascia of Fredet by colorectal surgeons.
ConclusionsA focused training intervention was associated with a strong trend toward increased ADRs among certified endoscopists. While the described training interventions definitely show promise, further efforts around continuing professional developments activities are needed to more consistently improve ADRS among certified endoscopists.
