Abstract
PURPOSE : A vertical margin (VM) distance of < 500 µm is a risk factor for recurrence in patients with T1 colorectal carcinoma (CRC) resected by endoscopy. We aimed to determine the effects of the VM distance on the recurrence and prognosis of T1 CRC. METHODS We enrolled 168 patients with T1 CRC who underwent additional surgery after endoscopic submucosal dissection (ESD) at multiple centers between 2008 and 2016. None of the patients were followed up for < 5 years. The enrolled 168 patients were classified into patients with VM distance of < 500 µm including positive VM (n = 72 [43%], VM distance < 500 µm group) and patients with VM distance of ≥ 500 µm (n = 96 [57%], VM distance ≥ 500 µm group). The clinicopathological features, recurrence rates, and prognoses were compared between the groups using propensity-score matching (PSM). RESULTS Tumors recurred in eight of the 168 patients (5%) with VM distance < 500 µm. After PSM, the rate of overall recurrence and local recurrence in the VM distance < 500 µm group were significantly higher than those in the VM distance ≥ 500 µm group. The 5-year recurrence-free survival rate was significantly higher in the VM distance ≥ 500 µm group than that in VM distance < 500 µm group after PSM (100% vs. 89%, p < 0.012). CONCLUSIONS Complete en bloc resection of T1 CRC via ESD must include a sufficient amount of SM to reduce the risk of metastasis and recurrence after additional surgery.

Abstract
INTRODUCTION To verify the value of the pathological criteria for additional treatment in locally resected pT1 colorectal carcinoma (CRC) which have been used in the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines since 2009. METHODS We enrolled 4,667 patients with pT1 CRC treated at 27 institutions between July 2009 and December 2016 (1,257 patients with local resection alone [group A], 1,512 patients with additional surgery after local resection [group B], and 1,898 patients with surgery alone [group C]). All 5 factors of the JSCCR guidelines (submucosal resection margin, tumor histologic grade, submucosal invasion depth, lymphovascular invasion, and tumor budding) for lymph node metastasis (LNM) had been diagnosed prospectively. RESULTS Any of the risk factors were present in 3,751 patients. The LNM incidence was 10.4% (95% confidence interval 9.4-11.5) in group B/C patients with risk factors, whereas it was 1.8% (95% confidence interval 0.4-5.3) in those without risk factors ( P < 0.01). In group A, the incidence of recurrence was 3.6% in patients with risk factors, but it was only 0.4% in patients without risk factors ( P < 0.01). The disease-free survival rate of group A patients classified as risk positive was significantly worse than those of groups B and C patients. However, the 5-year disease-free survival rate in group A patients with no risk was 99.6%. DISCUSSION Our large-scale real-world multicenter study demonstrated the validity of the JSCCR criteria for pT1 CRC after local resection, especially regarding favorable outcomes in patients with low risk of LNM.

Abstract
Background The treatment patterns and outcomes for patients after non-curative endoscopic submucosal dissection (ESD) remain controversial, particularly among those requiring preservation of the anal sphincter or advanced age. This retrospective study aimed to investigate the treatment patterns and outcomes in patients after non-curative ESD for early colorectal cancer (CRC). Methods This was a retrospective review in Chinese patients who received non-curative ESD for early CRC, and who were treated in the Cancer Hospital at the Chinese Academy of Medical Sciences from 2010 to 2019. Demographic parameters, clinicopathologic features, treatment patterns, and clinical outcomes were analyzed. Results Of the 180 patients who received non-curative ESD, 85 received additional surgery; the remaining 95 patients were kept under surveillance only. Patients in the surveillance-only group tended to be older than those in the additional surgery group. Furthermore, tumors in the surveillance-only group were located in the rectum significantly more often, were better differentiated with a shallower depth of invasion and less perineuronal invasion than in the additional surgery group; there were fewer high-risk factors for residual cancer or lymph node (LN) metastasis in the surveillance-only group compared with the additional surgery group. There was no significant difference in 5-year overall survival (OS) (92.6% versus 92.7%, P=0.355), 5-year disease-free survival (DFS) (94.7% versus 91.9%, P=0.340), 5-year cancer-specific survival (CSS) (93.8% versus 92.7%, P=0.791), or total recurrence rates (4.7% versus 9.5%, P=0.217) between the additional surgery and surveillance-only groups, respectively. Conclusions ESD results in favorable outcomes for patients with early CRC. Surveillance in patients who receive non-curative ESD may be an alternative option for those with advanced age and fewer high-risk factors for residual cancer or LN metastasis.

Risk of Covert Submucosal Cancer in Patients With Granular Mixed Laterally Spreading Tumors. Clin Gastroenterol Hepatol 2021; 19:1395-1401. [PMID: 32687977 DOI: 10.1016/j.cgh.2020.07.024] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 07/06/2020] [Accepted: 07/12/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Granular mixed laterally spreading tumors (GM-LSTs) have an intermediate level of risk for submucosal invasive cancer (SMICs) without clear signs of invasion (covert); the optimal resection method is uncertain. We aimed to determine the risk of covert SMIC in GM-LSTs based on clinical and endoscopic factors. METHODS We collected data from 693 patients (50.6% male; median age, 69 years) with colorectal GM-LSTs, without signs of invasion, who underwent endoscopic resection (74.2%) or endoscopic submucosal dissection (25.2%) at 7 centers in Italy from 2016 through 2019. We performed multivariate and univariate analyses to identify demographic and endoscopic factors associated with risk of SMIC. We developed a multivariate model to calculate the number needed to treat (NNT) to detect 1 SMIC. RESULTS Based on pathology analysis, 66 patients (9.5%) had covert SMIC. In multivariate analyses, increased risk of covert SMIC were independently associated with increasing lesion size (odds ratio per mm increase, 1.02, 95% CI, 1.01-1.03; P = .003) and rectal location (odds ratio, 3.08; 95% CI, 1.62-5.83; P = .004). A logistic regression model based on lesion size (with a cutoff of 40 mm) and rectal location identified patients with covert SMIC with 47.0% sensitivity, 82.6% specificity, and an area under the curve of 0.69. The NNT to identify 1 patient with a nonrectal SMIC smaller than 4 cm was 20; the NNT to identify 1 patient with a rectal SMIC of 4 cm or more was 5. CONCLUSIONS In an analysis of data from 693 patients, we found the risk of covert SMIC in patients with GM-LSTs to be approximately 10%. GM-LSTs of 4 cm or more and a rectal location are high risk and should be treated by en-bloc resection. ClinicalTrials.gov, Number: NCT03836131.

Tan T, Li SY. Application value of pre-cutting endoscopic mucosal resection in treatment of colorectal laterally spreading tumors. Shijie Huaren Xiaohua Zazhi 2020; 28:1272-1278. [DOI: 10.11569/wcjd.v28.i24.1272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Endoscopic mucosal resection (EMR) with precutting (Pre-cut-EMR) is an improvement on the basis of EMR, which combines the technical advantages of EMR and endoscopic submucosal dissection (ESD) to form a new endoscopic resection method and is more and more widely used in clinical practice. This study preliminarily explored the clinical value of Pre-cut-EMR in the treatment of colorectal laterally spreading tumors (LSTs) through retrospective analysis.
AIM To explore the application value of Pre-cut-EMR in the treatment of colorectal LSTs.
METHODS A total of 84 patients with colorectal LSTs who were treated at our department from January 2016 to December 2019 were selected as the research subjects. The clinical data of all patients were retrospectively analyzed to summarize the clinical characteristics of colorectal LSTs. All patients underwent Pre-cut-EMR, and the average operation time, overall resection rate, complete resection rate, and the incidence of complications were recorded. Colonoscopy was performed at 3, 6, and 12 mo after the operation to evaluate the recurrence. The relevant literature on ESD treatment of colorectal LSTs was retrieved through China HowNet and Wanfang Database, and the pre-cut-EMR group and ESD group were compared for the curative effect on colorectal LSTs.
RESULTS The average diameter of colorectal LSTs in the 84 cases was 25.6 mm. The endoscopic morphological classification was mainly granular. According to Kudo pit classification, types Ⅲ and Ⅳ were common, with type ⅢL being the most common. Tubular adenoma and villous adenoma were common pathological types. All 84 patients with colorectal LSTs underwent endoscopic resection successfully. One of them converted to ESD and one to EPMR. The pre-cut-EMR resection rate was 97.6%, and the average operation time was 24.5 min. There were three cases with positive basal margins, and the complete resection rate was 96.4%. Two cases of bleeding and one case of perforation occurred during the operation, and the complication rate was 3.6%. None of the 78 patients who were followed had recurrence, and the recurrence rate was 0%. Compared with the research data obtained by Xu et al, Yu et al, and Qiuhai et al, the operation time of the Pre-cut-EMR group was significantly lower than that of the ESD group (χ2 = 21.037, P = 0.001), but there was no statistical difference in the overall resection rate, complication rate, complete resection rate, or recurrence rate compared with the ESD group (P > 0.05).
CONCLUSION Pre-cut-EMR is effective and safe for colorectal LST treatment, and has high clinical value. This surgical method deserves to be widely promoted due to its simplicity, being easy to learn, and low equipment requirements.

Endosc Int Open 2020; 8:E1117-E1122.

Abstract
Background and study aims Based on pathology, locally resected T1 colorectal cancer (T1-CRC) can be classified as having low- or high-risk for irradicality and/or lymph node metastasis, the latter requiring adjuvant surgery. Reporting and application of pathological high-risk criteria is likely variable, with inherited variation regarding baseline oncological staging, treatment and surveillance. Methods We assessed practice variation using an online survey among gastroenterologists and surgeons participating in the Dutch T1-CRC Working Group. Results Of the 130 invited physicians, 53 % participated. Regarding high-risk T1-CRC criteria, lymphangio-invasion is used by 100 %, positive or indeterminable margins by 93 %, poor differentiation by 90 %, tumor-free margin ≤ 1 mm by 78 %, tumor budding by 57 % and submucosal invasion > 1000 µm by 47 %. Fifty-two percent of the respondents do not perform baseline staging in locally resected low-risk T1-CRC. In case of unoperated high-risk patients, we recorded 61 different surveillance strategies in 63 participants, using 19 different combinations of diagnostic tests. Endoscopy is used in all schedules. Mean follow-up time is 36 months for endoscopy, 26 months for rectal MRI and 30 months for abdominal CT (all varying 3-60 months). Conclusion We found variable use of pathological high-risk T1-CRC criteria, creating risk for misclassification as low-risk T1-CRC. This has serious implications, as most participants will not proceed to oncological staging in low-risk patients and adjuvant surgery nor radiological surveillance is considered. On the other hand, oncological surveillance in patients with a locally resected high-risk T1-CRC who do not wish adjuvant surgery is highly variable emphasizing the need for a uniform surveillance protocol.

Abstract
Background and Aims: Endoscopic resection (ER) for submucosal invasive colorectal cancer (T1 CRC) can be grouped as curative ER (C-ER) and non-curative ER (NC-ER). Little is known about the long-term outcomes of patients in these two groups. Therefore, we have evaluated the long-term outcomes in endoscopically resected T1 CRC patients in C-ER and NC-ER groups. Methods: We conducted a retrospective study on 220 patients with T1 CRC treated with ER from January 2007 to December 2017. First, we investigated the long-term outcomes (5-year overall survival [OS] and recurrence-free survival [RFS]) in the C-ER group (n = 49). In the NC-ER group (n = 171), we compared long-term outcomes between patients who underwent additional surgical resection (ASR) (n = 117) and those who did not (surveillance-only, n = 54). Results: T1 CRC patients in the C-ER and NC-ER groups had a median follow-up of 44 (interquartile range 32–69) months. There was no risk of tumor recurrence and cancer-related deaths in patients with C-ER. In the NC-ER group, the 5-year OS rates were 75.3% and 92.6% in the surveillance-only and ASR subgroups, respectively. The hazard ratio (HR) for ASR in NC-ER vs. surveillance-only in NC-ER was statistically insignificant. However, RFS rates were significantly different between the ASR (97.2%) and surveillance-only (84.0%) subgroups. Multivariate analysis indicated a submucosal invasion depth (SID) of >2500 µm and margin positivity to be associated with recurrence. Conclusions: The surveillance-only approach can be considered as an alternative surgical option for T1 CRCs in selected patients undergoing NC-ER.
