Purpose Treatment of rectal cancer with neoadjuvant radiotherapy has been shown to reduce local recurrence and improve overall survival. The role of chemoradiotherapy in patients with T2, N0 and early T3, N0 rectal cancer, treated by radical surgery with total mesorectal excision, remains controversial. The aim of this study was to identify predictors of recurrence in this group of patients to enhance treatment selection. Patients and Methods One hundred patients with primary T2-3, N0 adenocarcinoma of the rectum, uniformly treated by surgery alone, were studied. The pathology slides available for 97 patients were rereviewed. Three patients with incomplete data sets were excluded. Clinical and survival data were obtained from a prospective computerized database and updated from hospital and office charts. The study end points were disease-free survival, disease-specific survival (DSS), time to pelvic recurrence (PR), and distant recurrence. Results Complete follow-up was available for all study patients. Median follow-up was 79.5 months (range, 57.7 to 105.9 months). During this time period 30 patients (31.9%) died as a result of disease and 64 patients (68.1%) remained alive and disease free. Five-year DSS was 73%. The cumulative risk for PR was 8% at 5 years and 10% at 8 years. Lymphovascular invasion, preoperative serum carcinoembryonic antigen (CEA > 5 ng/mL) level, and age older than 70 years were all associated with adverse outcome. Conclusion Patients with T2-3, N0 rectal cancers and either lymphovascular invasion or elevated CEA levels have reduced survival and a higher incidence of PR, and should be considered for future randomized trials.

Introduction: Serum carcinoembryonic (CEA) antigen is used as a diagnostic screening tool during follow-up in colorectal cancer patients. However, it remains unclear whether preoperative serum CEA is a reliable marker in the follow-up to predict recurrence. The aim of the study is to determine the value of elevated pre- and postoperative serum carcinoembryonic antigen levels (CEA > 5 µg/L) as an independent prognostic factor for locoregional and distant recurrence in patients who underwent curative surgery for colorectal cancer. Methods: This single center retrospective observational cohort study includes patients who underwent curative surgery for colorectal cancer between 2005 and 2015 and had pre- and postoperative serum CEA measurements. Five-year disease-free survival and multivariate Cox regression analyses were performed to adjust for confounding factors. Results: Preoperative serum CEA level was measured in 2093 patients with colorectal cancer. No significant association was found between an elevated preoperative serum CEA and locoregional recurrence (adjusted hazard ratio (HR) 1.29 (95% confidence interval (CI) 0.91, 1.84; P=0.26)). However, a significant association was found between an elevated preoperative serum CEA and systemic recurrence (adjusted HR 1.58 (95% CI 1.25, 2.00; P<0.01)]. The five-year disease-free survival was lower in patients with elevated preoperative serum CEA levels ( P<0.01). Postoperative serum CEA level was the most sensitive for hepatic metastases during follow-up (73.3%). Conclusions: The preoperative serum CEA level is an independent prognostic factor for systemic metastasis after curative surgery for colorectal cancer in patients with stage I–III disease. The level is the most sensitive for hepatic metastasis compared to metastasis to other anatomic sites.

PURPOSE Patients with colon or rectal cancer were entered onto a prospectively randomized, controlled clinical trial of active specific immunotherapy (ASI) with an autologous tumor cell-bacillus Calmette-Guérin (BCG) vaccine. We investigated whether ASI could improve disease-free status and survival. PATIENTS AND METHODS Ninety-eight patients with Dukes' stage B2-C3 colon or rectal cancer were randomized into groups treated by resection alone or resection plus ASI. Eighty patients met all eligibility criteria. All patients with rectal cancer were to receive 50 Gy of pelvic irradiation. Analysis of distribution of survival and disease-free survival was made on all eligible patients until December 31, 1990. RESULTS As a single study, no statistically significant differences were detected in survival or disease-free survival for all 80 eligible patients. However, since it was recognized at the outset that there were treatment differences, in that rectal cancer patients were to receive postimmunotherapy radiation, it was considered that a cohort analysis of the colon and rectal cancer patients might be informative. With a median follow-up of 93 months, there is a significant improvement in survival (two-sided P = .02; hazards ratio, 3.97) and disease-free survival (two-sided P = .039; hazards ratio, 2.67) in all eligible colon cancer patients who received ASI. With a median follow-up of 58 months, no benefits were seen in patients with rectal cancer who received ASI. CONCLUSION This study suggests that ASI may be beneficial to patients with colon cancer.

Objective: Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most common colorectal cancer markers. We aimed to identify the appropriate clinical conditions for measuring serum CEA and CA19-9 levels before surgery and during follow-up. Methods: This study included 1275 colorectal cancer patients who were divided into 3 groups according to preoperative CEA levels (group A, ≤5 ng/mL; group B, &gt;5–≤11 ng/mL; group C, &gt;11 ng/mL). Each group was subdivided into 2 groups according to preoperative CA19-9 levels (cutoff level: ≤37 U/mL). Recurrence and survival rates were analyzed. Results: Recurrence rate, disease-free survival after curative surgery, and prognosis were significantly worse in group A and B patients with high CA19-9 levels. At recurrence, CEA levels showed a greater increase in group B and C patients; CA19-9 levels increased in group A patients with high CA19-9 levels. At recurrence, high serum CA19-9 levels were observed in group A patients with high preoperative serum CA19-9 levels, even if the serum CEA level did not increase. Preoperative CA19-9 levels could predict recurrence and prognosis in groups A and B. Conclusion: Periodic CA19-9 determination is useful for monitoring recurrence among group A patients with high CA19-9 levels.

Background: Management of rectal cancer has been evolved over the past two decades with the introduction of total mesorectal excision (TME) and laparoscopic resection. Objective: This study aims to assess the difference in the long term outcomes after laparoscopic and open resection for potentially curable, non-metastatic rectal cancer patients.Methods: This is a retrospective study which has been conducted in a single tertiary care center where the patients were recruited from the colorectal database of the Section of Colon and Rectal Surgery at King Faisal Specialist Hospital & Research Centre (KFSH&RC). It included all the patients who had non-metastatic rectal cancer and underwent laparoscopic or open curative resection regardless of their age or the comorbid status during the period from January 2012 – December 2015. We studied the long-term outcomes for those patients which included the completeness of resection of the tumor, overall 3-year survival, 3-year disease free survival, local recurrence and distal recurrence of the cancer.Results:120 patients were included in this study, 69 of them were males and 51 were females. 86 (71.7%) of them underwent open surgery while 34 (28.3%) underwent laparoscopic surgery. After a mean follow up of 32.4 months: 104 patients were alive, 7 deceased and 9 were lost of follow up. Local recurrence in the open approach (OA), and laparoscopic approach (LA) groups was 3/86 (3.5%) and 4/34 (11.8%) respectively. Distal recurrence occurred in 12/86 (14%) of OA and 5/34 (14.7%) of LA. Overall 3-years survival for OA and LA was 89% and 97% respectively and the 3-years disease free survival was 49% and 57% respectively.Conclusion: Laparoscopic and open rectal excision were similar in their outcome.

The Ferguson Operating Anoscope (FOA) is a surgical instrument, which can facilitate transanal excision of appropriate rectal tumors within 15 cm of the anal verge. Previous work showed low recurrence (4.3%) for favorable T1 tumors (no lymphovascular invasion, well/moderate differentiation, negative margins). This follow-up study evaluates outcomes in rectal cancer excised with FOA at a tertiary care center. T1 rectal cancer patients were identified in a prospectively maintained database. Tumor pathology and patient characteristics were reviewed. Primary outcomes include tumor recurrence and patient and disease-free survival. Secondary outcomes are quality of excision (intact specimen). Twenty-eight patients had pathologic stage T1 rectal cancer (average 8 ± 2.6 cm from the anal verge). Final path demonstrated 14 per cent to be well differentiated, 82 per cent moderately differentiated, and 93 per cent without angiolymphatic invasion. All specimens removed were intact. One patient had a true local recurrence and underwent a salvage operation 24 months after her index operation. Patient survival was 96.4 per cent (n = one death from primary lung cancer) at median follow-up 64 ± 35 months. With appropriate tumor selection and quality of initial resection, FOA has demonstrated utility in achieving optimal oncologic resection of T1 rectal tumors.

AbstractResistance to chemotherapy remains the major cause of treatment failure in patients with colorectal cancer (CRC). Here, we identified TRIM25 as an epigenetic regulator of oxaliplatin (OXA) resistance in CRC. The level of TRIM25 in OXA-resistant patients who experienced recurrence during the follow-up period was significantly higher than in those who had no recurrence. Patients with high expression of TRIM25 had a significantly higher recurrence rate and worse disease-free survival than those with low TRIM25 expression. Downregulation of TRIM25 dramatically inhibited, while overexpression of TRIM25 increased, CRC cell survival after OXA treatment. In addition, TRIM25 promoted the stem cell properties of CRC cells both in vitro and in vivo. Importantly, we demonstrated that TRIM25 inhibited the binding of E3 ubiquitin ligase TRAF6 to EZH2, thus stabilizing and upregulating EZH2, and promoting OXA resistance. Our study contributes to a better understanding of OXA resistance and indicates that inhibitors against TRIM25 might be an excellent strategy for CRC management in clinical practice.

PURPOSE: To determine the toxicity and recommended phase II doses of the combination of fludarabine plus cyclophosphamide in chemotherapy-naive patients with low-grade lymphoma. PATIENTS AND METHODS: Previously untreated patients with low-grade lymphoma were entered onto dosing cohorts of four patients each. The cyclophosphamide dose, given on day 1, was increased from 600 to 1,000 mg/m2. Fludarabine 20 mg/m2 was administered on days 1 through 5. The first eight patients were treated every 21 days; later patients were treated every 28 days. Prophylactic antibiotics were required. RESULTS: Prolonged cytopenia and pulmonary toxicity each occurred in three of eight patients treated every 3 weeks. The 19 patients treated every 28 days, who were given granulocyte colony-stimulating factor as indicated, did not have undue nonhematologic toxicity. Dose-limiting toxicity was hematologic. At the recommended phase II/III dose (cyclophosphamide 1,000 mg/m2), grade 4 neutropenia was observed in 17% of all cycles and 31% of first cycles. Grade 3 or 4 thrombocytopenia was seen in only 1% of all cycles. The median number of cycles per patient was six (range, two to 11) for all patients enrolled. The response rate was 100% of 27 patients entered; 89% achieved a complete and 11% a partial response. Nineteen of 22 patients with bone marrow involvement had clearing of the marrow. Median duration of follow-up was more than 5 years; median overall and disease-free survival times have not been reached. Kaplan-Meier estimated 5-year overall survival and disease-free survival rates were 66% and 53%, respectively. CONCLUSION: The recommended dosing for this combination in patients with previously untreated low-grade lymphoma is cyclophosphamide 1,000 mg/m2 day 1 and fludarabine 20 mg/m2 days 1 through 5. The regimen has a high level of activity, with prolonged complete remissions providing 5-year overall and disease-free survival rates as high as those reported for other therapeutic approaches in untreated patients.
