Rational staging and follow-up of colorectal cancer : Do guidelines provide further help?

[Rational staging and follow-up of colorectal cancer : Do guidelines provide further help?] Radiologe. 2019 Aug 27;: Authors: Juchems MS, Wessling J Abstract CLINICAL/METHODICAL ISSUE: Colorectal cancer is one of the most common malignant tumors. Preoperative imaging is crucial in rectal cancer as patients can only receive optimal treatment when accurate staging is performed. The N‑staging is often difficult with the available options and must be called into question as a staging parameter. STANDARD RADIOLOGICAL METHODS: Endoscopic ultrasound (EUS) and magnetic resonance imaging (MRI) are particularly suitable for local staging. Multiparametric MRI with diffusion imaging is indispensable for tumor follow-up. METHODICAL INNOVATIONS: The assessment of infiltration of the mesorectal fascia is best accomplished using high-resolution MRI. In addition, extramural vascular infiltration (EMVI) has become established as another important prognostic factor. After neoadjuvant therapy and restaging of locally advanced rectal cancer, the identification and validation of prognostically relevant image parameters are prioritized. Multiparametric MRI of the rectum including diffusion imaging as well as the application of radiological and pathological scores (MR-TRG) are becoming increasingly more important in this context. ASSESSMENT: For the radiologist it is important to become familiar with indicators of the resectability of rectal cancer and to ...

This article aimed to summarize current status of colorectal cancer (CRC) in Thailand. In brief, CRC is the third most common cancer and accounts for 11% of cancer burden in Thailand. It was the only malignancy with increased incidence in both genders in Thailand. Over 10,000 new CRC cases occurred annually and about 40% were rectal cancer. Due to the lack of CRC screening and public awareness, non-metastatic cancer was accounted only for 20-30% of overall cases. The demand for general or colorectal surgeons outmatches the supply with a ratio of 1 general surgeon to 35,000 individuals. There are about 70 board-certified co...

Conclusion: The triple-staple technique is a safe alternative to the double-staple anastomosis after anterior resection. It also effectively shortens the operating time. PMID: 32054240 [PubMed - as supplied by publisher]

Traditionally, rectal cancer radiation therapy uses bony landmark fields to cover common lymphatic drainage sites, including the internal iliac, presacral, and perirectal lymph nodes. We aimed to investigate if bony landmark borders sufficiently cover the internal iliac nodes and to compare tumor volume and normal tissue avoidance using classic bony landmarks (c3DCRT), contoured elective clinical target volume (f3DCRT), and volumetric modulated arc therapy (VMAT) planning in locally advanced rectal cancer.

CONCLUSIONS: A DNA repair gene score may predict patients likely to have poor response to chemoradiation. This score may be a relevant tool to be investigated in future studies focused on chemoradiation used in the context of organ preservation. See Video Abstract at http://links.lww.com/DCR/B104.

CONCLUSIONS: Although the whole-body PET/MRI was more accurate than the pelvic MRI alone for the prediction of tumor and node response to preoperative chemoradiotherapy, the technique performed worse than CT in detecting small lung metastasis.

CONCLUSIONS: The number of hospitals performing rectal cancer resections in New York State is decreasing and volume by center is increasing. There was a statistically significant difference in the mean distance traveled by patients over time. If rectal cancer resections were centralized to high-volume centers, the mean travel distance would increase by 9.5 miles. There would be a 321% increase in the number of patients having to travel 50+ miles for surgery. Any plan for centralization in New York State will require careful planning to avoid placing undue travel burden on patients. See Video Abstract at http://links.lww....

CONCLUSIONS: In a universal healthcare system, young age was associated with increased lymph node positivity of colon and rectal cancers, suggesting that factors other than access to care may play a role in this association.
