RESUMO
AIM: In 2014, a national colorectal cancer (CRC) screening programme was launched in the Netherlands. It is difficult to assess for the individual patients with CRC whether the oncological benefits of surgery will outweigh the morbidity of the procedure, especially in early lesions. This study compares patient and tumour characteristics between screen-detected and nonscreen-detected patients. Also, we present an overview of treatment options and clinical dilemmas when treating patients with early-stage colorectal disease. METHOD: Between January 2014 and December 2016, all patients with nonmalignant polyps or CRC who were referred to the Department of Surgery of the Leiden University Medical Centre in the Netherlands were included. Baseline characteristics, type of treatment and short-term outcomes of patients with screen-detected and nonscreen-detected colorectal tumours were compared. RESULTS: A total of 426 patients were included, of whom 240 (56.3%) were identified by screening. Nonscreen-detected patients more often had comorbidity (P = 0.03), the primary tumour was more often located in the rectum (P = 0.001) and there was a higher rate of metastatic disease (P < 0.001). Of 354 surgically treated patients, postoperative adverse events did not significantly differ between the two groups (P = 0.38). Of 46 patients with T1 CRC in the endoscopic resection specimen, 23 underwent surgical resection of whom only 30.4% had residual invasive disease at colectomy. CONCLUSION: Despite differences in comorbidity, stage and surgical outcome of patients with screen-detected tumours compared to nonscreen-detected tumours were not significantly different. Considering its limited oncological benefits as well as the rate of adverse events, surgery for nonmalignant polyps and T1 CRC should be considered carefully.

BACKGROUND: In patients with stenosing colorectal cancer (CRC), visualization of the entire colon prior to surgery is recommended to exclude synchronous tumors. Therefore, most centers combine computed tomographic colonography (CTC) with staging CT. The aims of this study were to evaluate the yield and clinical implications of CTC. METHODS: In this multicenter retrospective study, patients with stenosing CRC that underwent CTC and subsequent surgery between April 2013 and November 2015 were included. Result of the CTC, its influence on the surgical treatment plan, and final histology report were evaluated. RESULTS: One hundred sixty-two patients with stenosing CRC were included. Nine (5.6 %) synchronous cancers proximal to the stenosing tumor were suspected with CTC. In four of nine patients, the CTC did not change the primary surgical plan because the tumors were located in the same surgical segment. In five of nine patients, CTC changed the surgical treatment plan. Three of these five patients underwent an extended resection and the presence of the tumors was confirmed. Two of these three synchronous CRCs were also visible on abdominal staging CT. In the other two patients, the result of CTC was false positive which led to an unnecessary extended resection in one patient. CONCLUSION: The yield of CTC was relatively low. In only three patients (1.9 %), CTC correctly changed the primary surgical plan, but in two of them, the tumor was also visible on abdominal staging CT. Moreover, in two patients, CTC was false positive. The clinical value of CTC in stenosing CRC appears to be limited.

BACKGROUND: Many patients with locally recurrent rectal cancer receive radiotherapy for the treatment of the primary tumour. It is unclear whether reirradiation is safe and effective when a local recurrence develops. The aim of this study was to evaluate the toxicity and oncological outcome of reirradiation in patients with locally recurrent rectal carcinoma. METHODS: From March 1994 until December 2013, data on patients with locally recurrent rectal cancer (without distant metastasis) were entered into a database. Patients were reirradiated with a reduced dose of 30 Gy and received an intraoperative electron radiotherapy boost during surgery. Morbidity associated with radiotherapy, postoperative complications and oncological outcome were evaluated. RESULTS: Clear margins (R0) were obtained in 75 (55·6 per cent) of the 135 patients who were reirradiated. Forty-six patients developed serious postoperative complications and the 30-day mortality rate was 4·6 per cent. Multivariable analysis showed that margin status was the main factor influencing oncological outcome (hazard ratio for overall survival 2·51 for R1 and 3·19 for R2 versus R0 resection; both P < 0·001). There was no significant difference in survival between the reirradiated group and a group of 113 patients who had full-course irradiation (5-year overall survival rate 34·1 and 39·1 per cent respectively; P = 0·278). Both reirradiation and full-course irradiation were associated with better survival than no irradiation in a historical control group of 24 patients (5-year overall survival rate 23 per cent; P = 0·225 and P = 0·062). CONCLUSION: Reirradiation (with concomitant chemotherapy) has few side-effects and complements radical resection of recurrent rectal cancer.

BACKGROUND: Decreased cancer specific survival in older colorectal patients is mainly due to mortality in the first year, emphasizing the importance of the first postoperative year. This study aims to gain an overview and time trends of short-term mortality in octogenarians (≥80 years) with colorectal cancer across four North European countries. METHODS: Patients of 80 years or older, operated for colorectal cancer (stage I-III) between 2005 and 2014, were included. Population-based cohorts from Belgium, Denmark, the Netherlands, and Sweden were collected. Separately for colon- and rectal cancer, 30-day, 90-day, one-year, and excess one-year mortality were calculated. Also, short-term mortality over three time periods (2005-2008, 2009-2011, 2012-2014) was analyzed. RESULTS: In total, 35,158 colon cancer patients and 10,144 rectal cancer patients were included. For colon cancer, 90-day mortality rate was highest in Denmark (15%) and lowest in Sweden (8%). For rectal cancer, 90-day mortality rate was highest in Belgium (11%) and lowest in Sweden (7%). One-year excess mortality rate of colon cancer patients decreased from 2005 to 2008 to 2012-2014 for all countries (Belgium: 17%-11%, Denmark: 21%-15%, the Netherlands: 18%-10%, and Sweden: 10%-8%). For rectal cancer, from 2005 to 2008 to 2012-2014 one-year excess mortality rate decreased in the Netherlands from 16% to 7% and Sweden: 8%-2%). CONCLUSIONS: Short-term mortality rates were high in octogenarians operated for colorectal cancer. Short-term mortality rates differ across four North European countries, but decreased over time for both colon and rectal cancer patients in all countries.

OBJECTIVE: Aim of this study is analysing the pooled results of Intra-Operative Electron beam Radiotherapy (IOERT) containing multimodality treatment of locally recurrent rectal cancer (LRRC) of two major treatment centres. METHODS AND MATERIALS: Five hundred sixty five patients with LRRC who underwent multimodality-treatment up to 2010 were studied. The preferred treatment was preoperative chemo-radiotherapy, surgery and IOERT. In uni- and multivariate analyses risk factors for local re-recurrence, distant metastasis free survival, relapse free survival, cancer-specific survival and overall survival were studied. RESULTS: Two hundred fifty one patients (44%) underwent a radical (R0) resection. In patients who had no preoperative treatment the R0 resection rate was 26%, and this was 43% and 50% for patients who respectively received preoperative re-(chemo)-irradiation or full-course radiotherapy (p < 0.0001). After uni- and multivariate analysis it was found that all oncologic parameters were influenced by preoperative treatment and radicality of the resection. Patients who were re-irradiated had a similar outcome compared to patients, who were radiotherapy naive and could undergo full-course treatment, except the chance of local re-recurrence was higher for re-irradiated patients. Waiting-time between preoperative radiotherapy and IOERT was inversely correlated with the chance of local re-recurrence, and positively correlated with the chance of a R0 resection. CONCLUSIONS: R0 resection is the most important factor influencing oncologic parameters in treatment of LRRC. Preoperative (chemo)-radiotherapy increases the chance of achieving radical resections and improves oncologic outcomes. Short waiting-times between preoperative treatment and IOERT improves the effectiveness of IOERT to reduce the chance of a local re-recurrence.

BACKGROUND: Implementation of mass colorectal cancer screening, using faecal occult blood test or colonoscopy, is recommended by the European Union in order to increase cancer-specific survival by diagnosing disease in an earlier stage. Post-colonoscopy complications have been addressed by previous systematic reviews, but morbidity of colorectal cancer screening on multiple levels has never been evaluated before. AIM: To evaluate potential harm as a result of mass colorectal cancer screening in terms of complications after colonoscopy, morbidity and mortality following surgery, psychological distress and inappropriate use of the screening test. METHODS: A systematic review of all literature on morbidity and mortality attributed to colorectal cancer screening, using faecal occult blood test or colonoscopy, from each databases' inception to August 2016 was performed. A meta-analysis was conducted to examine the pooled incidence of major complications of colonoscopy (major bleedings and perforations). RESULTS: Sixty studies were included. Five out of seven included prospective studies on psychological morbidity reported an association between participation in a colorectal screening program and psychological distress. Serious morbidity from colonoscopy in asymptomatic patients included major bleedings (0.8/1000 procedures, 95% CI 0.18-1.63) and perforations (0.07/1000 procedures, 95% CI 0.006-0.17). CONCLUSIONS: Participation in a colorectal cancer screening program is associated with psychological distress and can cause serious adverse events. Nevertheless, the short duration of psychological impact as well as the low colonoscopy complication rate seems reassuring. Because of limited literature on harms other than perforation and bleeding, future research on this topic is greatly needed to contribute to future screening recommendations.

In the last decennia, the length of hospital stay of admitted patients has significantly decreased in all medical fields. As a result, postoperative recovery mainly takes place at home, inherently leading to new challenges. Here, two patients are being discussed for whom the postoperative period was substandard. To guarantee optimal quality of care in the home situation, the medical specialist and the general practitioner need to make the necessary arrangements. We would first of all recommend providing each discharged patient with specific, structured and individualised advices regarding postoperative recovery but also regarding alarm symptoms and logistics (e.g. who to call in case of emergency). Finally, we believe that, as (serious) complications are rare, it should be agreed on the fact that the responsible medical specialist is the coordinator of the postoperative period and the first contact point for postoperative patients.

Hepatocellular carcinoma (HCC) is one of the most common primary cancers in the world and the third most common cause of cancer mortality world-wide. Surgery is the gold standard in the treatment of patients with HCC. The prognosis is mainly determined by the underlying liver disease and recurrent rates. In the Western World, up to 30% of the patients with HCC have a non-cirrhotic liver. The main prognostic factor in this special group of patients are the recurrences. Most recurrences are intrahepatic; however, 30% of the recurrences are extrahepatic. The role of resection in case of intrahepatic recurrences is widely accepted, particularly in the non-cirrhotic liver. The role of resection in extrahepatic HCC recurrences is not well established and unknown among many physicians. We present two patients with HCC in a non-cirrhotic liver with extrahepatic recurrences and long-term survival after resection. The corresponding literature support an aggressive approach in case of extrahepatic HCC recurrence in selected cases: resectable metastasis, preserved liver function, absence of intracranial metastasis and control of the primary tumour. Further research is warranted because of the limited number of reports and the absence of randomized trials.
