BACKGROUND: We aimed to clarify the long-term outcomes of patients with T1 colorectal carcinoma (CRC) after endoscopic resection (ER) and surgical resection. METHODS: We examined T1 CRC patients treated during 1992-2008 and who had ≥5 years of follow-up. Patients who did not meet the curative criteria after ER according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines were defined as "non-endoscopically curable" and classified into three groups: ER alone (Group A: 121 patients), additional surgery after ER (Group B: 238 patients), and surgical resection alone (Group C: 342 patients)...

Colorectal cancer resembling submucosal tumor (SMT) is very rare. We herein report two cases of small colon carcinoma resembling SMT (80-year-old female and 67-year-old male), which massively invaded into the submucosal layer and accompanied marked lymphatic invasion and lymph node metastasis. We also reviewed the reported cases of colorectal carcinoma resembling SMT (SMT-like group, n=70) and analyzed the clinicopathological characteristics of this group compared with typical colorectal carcinoma cases operated at our institution (control group, n=1723)...

PURPOSE: Data evaluating the risk of lymph node metastasis depending upon the location of the primary tumor are limited in patients with T1 colorectal cancer. We aimed to evaluate the impact of tumor location on lymph node metastasis in T1 colorectal cancer. METHODS: Patients who underwent an oncologic resection with curative intent for T1 adenocarcinoma of the colon and rectum between January 1997 and October 2014 were assessed. Exclusion criteria were distant organ metastases, previous or concurrent cancer, past history of surgical or medical cancer treatment, preoperative chemoradiation, and patients with inflammatory bowel disease or polyposis syndromes...

Early colon cancer (ECC) has been defined as a carcinoma with invasion limited to the submucosa regardless of lymph node status and according to the Royal College of Pathologists as TNM stage T1 NX M0. As the potential risk of lymph node metastasis ranges from 6 to 17% and the preoperative assessment of lymph node metastasis is not reliable, the management of ECC is still controversial, varying from endoscopic to radical resection. A meeting on recent advances on the management of colorectal polyps endorsed by the Italian Society of Colorectal Surgery (SICCR) took place in April 2014, in Genoa (Italy)...

This study investigated the effects of stable transfection of the exogenous wild-type DCC gene on growth of the human colorectal carcinoma cell line SW1116 in vitro. The DCC gene was amplified from normal human colon tissue by reverse transcription-polymerase chain reaction and used to construct a recombinant expression plasmid, pcDNA3.1(+)-DCC. DCC-negative SW1116 cells were transfected with pcDNA3.1(+)-DCC. Cell viability was tested by the methyl thiazolyl tetrazolium (MTT) assay. Immunofluorescence staining was used to determine the effects of pcDNA3...

BACKGROUND: Radical resection with total mesorectal excision (TME) is the accepted standard of care for most rectal cancers. However, T1 rectal cancers may be at low risk for metastases and are therefore treatable with local resection. The aim of our study was to investigate whether the identification of these patients is possible through existing selection criteria. METHODS: Between 2001 and 2012, radical resection with TME was performed in 68 patients with a histologically confirmed T1 adenocarcinoma of the rectum...

BACKGROUND: The survival paradox between stage IIB/C (T4N0) and stage IIIA (T1-2N1) colon cancer remains in the 7th edition of the American Joint Committee on Cancer staging system. This multicenter study aimed to compare the oncologic outcomes of T4N0 and T1-2N1 colon cancers and to investigate the presumptive prognostic factors that might influence the survival paradox. METHODS: Patients who underwent curative surgery for pT4N0 (n = 224) and pT1-2N1 (n = 135) primary colon cancer between January 1999 and December 2010 at five tertiary referral cancer centers were included for analysis...

BACKGROUND: The standard therapy for stage I rectum cancer is surgical resection. Currently, there is no strong evidence to suggest that any type of adjuvant therapy is beneficial. The risks of local relapse and distant metastasis are higher in rectal tumors. Therefore, while there is no clearly defined absolute indication for adjuvant therapy in lymph node negative colon cancers, rectum tumors that are T3N0 and higher require adjuvant treatment. Due to the more aggressive nature of rectal cancers, we explored the clinical and pathologic factors that could predict the risk of relapse in Stage I (T1-T2) disease and whether there was any progression-free survival benefit to adjuvant therapy...

According to the Japanese Society for Cancer of the Colon and Rectum Guidelines 2014 for the Treatment of Colorectal Cancer, cases with T1 colorectal carcinoma should be considered for additional colectomy with lymph node dissection when histologically complete en bloc resection is endoscopically carried out and when one of the four risk factors listed below is present. These four risk factors are: (i) submucosal (SM) invasion depth ≥1000 μm; (ii) positive vascular invasion; (iii) poorly differentiated adenocarcinoma, signet ring cell carcinoma, or mucinous carcinoma; and (iv) grade 2/3 budding at the deepest part of SM invasion...

BACKGROUND: The Japanese Society for Cancer of the Colon and Rectum Guidelines for the Treatment of Colorectal Cancer 2010 state that curable T1 colorectal carcinoma (CRC) after endoscopic resection shows favorable histologic grade, absence of vessel involvement, submucosal invasion depth of <1,000 μm, and low-grade tumor budding. METHODS: We evaluated 322 consecutive T1 CRCs with LN dissection between January 1993 and March 2012. According to the muscularis mucosae condition, CRCs were classified into three groups: type A, clearly identified; type B, incompletely disrupted with deformity; or type C, completely disrupted...

The patient was a 68-year-old man who was admitted to our hospital with a liver tumor. Abdominal ultrasonography and computed tomography revealed a liver tumor 30 mm in diameter. On colonoscopy, a pedunculated tumor with a central depression (20 mm in diameter) was observed in the ascending colon, and this tumor was considered to be invading deeply into the submucosal layer. Right hemicolectomy with D3 lymphadenectomy and partial hepatectomy were performed simultaneously. On histopathological examination of the resected specimen, the tumor was a well-differentiated tubular adenocarcinoma with 3,000 μm invasion of the submucosal layer...

Recent advances in endoscopic diagnosis and treatment techniques have led to a marked increase in the detection and endoscopic treatment of early colorectal cancers (CRC). According to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines, T1-CRC with a negative vertical margin, well- or moderately differentiated adenocarcinoma, no evidence of vascular or lymphatic invasion, and depth of invasion <1000 μm are considered to have a low risk of lymph node metastasis. However, T1-CRC with any of these risk factors are considered to have a high risk of lymph node metastasis...
