ConclusionTreatment decisions must be individualized, and depend on the presence of systemic disease. Selected patients may benefit from resection of metastases, and PET scan may be useful to identify patients who will benefit from resection.
Conclusions: The percentage of ADC increase, as an optimized predictor unaffected by different b-values, may have a significant role in differentiating those patients with a good response to N-CRT from those with a poor response. PMID: 31737679 [PubMed - in process]

MR imaging plays a crucial role in the post-CRT assessment of rectal cancer; results are used for treatment planning. Radiologists should assess response or progression, possibility of a complete response, risk factors for incomplete resection, and nodal stage. T2-weighted MR imaging with diffusion-weighted imaging yields the best results to identify a complete response, but endoscopy is also very important. Overstaging of transmural and MRF invasion after CRT occur regularly, owing to residual stranding regarded as tumor to err on the safe side. Nodal restaging is a challenge. A structured report format or checklist is recommended.
AbstractPurposePreoperative short-course radiotherapy (PSRT) and preoperative long-course radiotherapy (PLRT) are standard treatment regimens for locally advanced rectal cancer. However, whether the efficacy and safety of PSRT with delayed surgery (more than 4 weeks) are superior to those of PLRT remains unresolved and was explored in this meta-analysis.MethodsStudies published in PubMed, Embase, the Cochrane Library, andClinicalTrials.gov databases were systematically searched. RevMan 5.3 was used to calculate pooled hazard ratios (HR) and relative risk (RR).ResultsSeven studies including 4973 patients were identifi...

ConclusionCRT should be considered for cT3N0 patients, but its timing (neoadjuvant vs. adjuvant) seems not to affect the disease-free survival in the present cohort of patients.
CONCLUSIONS: neoadjuvant chemotherapy is a promising alternative in the locally advanced rectal cancer setting and further phase III clinical trials are clearly warranted. PMID: 31729235 [PubMed - as supplied by publisher]
AbstractAbdomino-perineal resection (APR) for rectal cancer is challenging, due to the difficult exposure of the surgical field. Many investigations proved worst results in terms of circumferential resection margin (CRM) involvement compared to rectal anterior resection (RAR) with total mesorectal excision (TME). Extralevator abdomino-perineal excision (ELAPE) improved oncologic outcomes, but is burdened by important limitations (positioning, wound closure). Applying the concept of transanal minimally invasive surgery (TAMIS) and the experience in transanal TME (TaTME) to the perineal phase of APR could overcome these limi...
CONCLUSION: The various evaluation methods for predicting a pCR after PCRT show a predictive sensitivity of 0.15-0.41 for primary tumors and 0.52-0.88 for lymph nodes. Endoscopy is a relatively superior modality for predicting the pCR of the primary tumor of LARC patients. PMID: 31726004 [PubMed]
