Abstract
We present a case of cardiac tamponade after lung resection. A 68-year-old man underwent single-staged bilateral lung resection (right wedge resection and left S8 segmentectomy) for metastatic lung tumors from rectal cancer and lost consciousness on postoperative day 4. Because an enhanced whole-body computed tomography scan showed pericardial effusion as the only abnormal finding, we performed rethoracotomy, which revealed that the cardiac tamponade was due to coronary artery rupture. We suggest that it would be more reasonable to approach the pericardial space by rethoracotomy rather than median sternotomy because exploration of the surgical site is the first essential step.

Survival impact of surgical resection of primary tumor in patients with stage IV colorectal cancer: results from a large population-based cohort study. Cancer 2013; 120:683-91.

Abstract
BACKGROUND Currently, there is very low-quality evidence available regarding benefit of surgical resection of the primary tumor (SRPT), in patients with stage IV colorectal cancer (CRC). In the absence of randomization, the reported benefit may reflect selection of younger and healthier patients with good performance status. A large population-based cohort study was undertaken to determine the survival benefit of SRPT in advanced CRC by eliminating various biases reported in the literature. METHODS A retrospective cohort study involving patients with stage IV CRC, diagnosed between 1992 and 2005, in the province of Saskatchewan, Canada. Survival was estimated by using the Kaplan-Meier method. Survival distribution was compared by log-rank test. Cox proportional multivariate regression analysis was performed to determine survival benefit of SRPT by controlling other prognostic variables. RESULTS A total of 1378 eligible patients were identified. Their median age was 70 years (range, 22-98 years) and male:female ratio was 1.3:1; 944 (68.5%) of them underwent SRPT. Among 1378 patients, 42.3% received chemotherapy and 19.1% received second-generation therapy. Patients who underwent SRPT and received chemotherapy had median overall survival of 18.3 months (95% confidence interval [CI] = 16.6-20 months) compared with 8.4 months (95% CI = 7.1-9.7 months) if they were treated with chemotherapy alone (P < .0001). Cox proportional analysis revealed that use of chemotherapy (hazard ratio [HR] = 0.47, 95% CI = 0.41-0.54), SRPT (HR = 0.49, 95% CI = 0.41-0.58), second-line chemotherapy (HR = 0.47, 95% CI = 0.45-0.64), and metastasectomy (HR = 0.54, 95% CI = 0.45-0.64) were correlated with superior survival. CONCLUSIONS SRPT improves survival in patients with stage IV CRC, independent of other prognostic variables including age, performance status, comorbid illness and chemotherapy.

Abstract
INTRODUCTION Although the conventional treatment of patients with stage iv colorectal cancer involves resection of the primary tumor followed by chemotherapy, several studies suggest that in patients with few symptoms the first and only treatment should be chemotherapy. The objective of this study is to analyze the complications related to the primary tumor in a series of patients with unresectable metastatic colorectal cancer treated with chemotherapy without surgery. MATERIAL AND METHODS Retrospective descriptive study. The study included all patients with unresectable metastatic colorectal cancer treated with chemotherapy without resection of the primary tumor (January 2007-February 2011). RESULTS The mean age of the 61 patients analyzed was 67±13 years and the performance status was 0-1 in 53 (87%). Twenty (33%) patients developed complications during follow-up. The most common complication was intestinal obstruction in 15 (25%) patients followed by perforation. Complications required surgery in 6 (10%) cases. We did not find differences in patient characteristics between those who had a complication and those without, although the complication rate in patients with a colonic stent (53%) was twice that of other patients (26%). CONCLUSIONS Chemotherapy without surgery is a good option in most patients with unresectable metastatic colorectal cancer. However, although the percentage of patients requiring surgery is low, the total number of complications related to the primary tumor is not negligible. Studies are needed to identify those patients in whom a prophylactic colectomy could be indicated.

Abstract
PURPOSE Surgical resection of the primary tumour in patients with advanced colorectal cancer (crc) remains controversial. This review compares survival in patients with advanced crc who underwent surgical resection of the primary tumour with that in patients not undergoing resection, and determines rates of post-operative mortality and nonfatal complications, the primary tumour complication rate, the non-resection surgical procedures rate, and quality of life (qol). METHODS Reports in the central, medline, and embase databases were searched for relevant studies, which were selected using pre-specified eligibility criteria. The search was also restricted to publication dates from 1980 onward, the English language, and studies involving human subjects. Screening, evaluation of relevant articles, and data abstraction were performed in duplicate, and agreement between the abstractors was assessed. Articles that met the inclusion criteria were assessed for quality using the Newcastle-Ottawa Scale. Data were collected and synthesized per protocol. RESULTS From among the 3379 reports located, fifteen retrospective observational studies were selected. Of the 12,416 patients in the selected studies, 8620 (69%) underwent surgery. Median survival was 15.2 months (range: 10-30.7 months) in the resection group and 11.4 months (range: 3-22 months) in the non-resection group. Hazard ratio for survival was 0.69 [95% confidence interval (ci): 0.61 to 0.79] favouring surgical resection. Mean rates of postoperative mortality and nonfatal complications were 4.9% (95% ci: 0% to 9.7%) and 25.9% (95%ci: 20.1% to 31.6%) respectively. The mean primary tumour complication rate was 29.7% (95% ci: 18.5% to 41.0%), and the non-resection surgical procedures rate in the non-resection group was 27.6% (95 ci: 15.4% to 39.9%). No study provided qol data. CONCLUSIONS Although this review supports primary tumour resection in advanced crc, the results have significant biases. Randomized trials are warranted to confirm the findings.

Abstract
Colorectal cancer (CRC) is a leading worldwide health concern that is responsible for thousands of deaths each year. The primary source of mortality for patients with CRC is the development and subsequent progression of metastatic disease. The most common site for distant metastatic disease is the liver. Although patients with metastatic disease to the liver have several effective treatment options, the only one for cure remains surgical resection of the liver metastases. Historically, most patients with liver metastases have had unresectable disease, and only a small percentage of patients have undergone complete curative resection. However, improved systemic therapies have led to an evolution in strategies to treat metastatic CRC to the liver. Under most conditions the management of these patients remains complex; and as chemotherapy options and new targeted therapies continue to improve outcomes, it is clear that a multidisciplinary approach must be the foundation on which advanced surgical and medical techniques are employed. Here, in this review, we highlight the role of targeted therapies in the surgical management of patients with metastatic CRC to the liver.

Abstract
BACKGROUND Colorectal cancer (CRC) is the one of the most common malignancies and is a leading cause of cancer death worldwide. The incidence of mortality from CRC has decreased in Western countries because of earlier diagnosis and improved treatment modalities; however, mortality is still increasing in most other regions of the world. SUMMARY Progress in the development of imaging modalities has enabled more accurate staging based on the TNM classification. The therapeutic management of CRC should involve a multi-modal approach, including high-quality surgery and an optimal choice of chemotherapy and radiotherapy regimens according to disease characteristics and patient preferences. Even in the case of metastatic disease, the optimal multi-modal treatments could achieve potential cure or long-term survival benefit in some patients. The aim of this review is to present current options regarding the diagnosis, staging and treatment management for CRC based on published research reports and the current management guidelines.

Abstract
BACKGROUND Surgery-induced acceleration of tumour growth has been observed since several centuries. METHODS We reviewed recent insights from in vitro data, animal experimentation, and clinical studies on how surgery-induced wound healing or resection of a primary cancer influences the tumour-host ecosystem in patients harbouring minimal residual or metastatic disease. RESULTS Most of the growth factors, chemokines, and cytokines orchestrating surgical wound healing promote tumour growth, invasion, or angiogenesis. In addition, resection of a primary tumour may accelerate synchronous metastatic growth. In the clinical setting, indirect evidence supports the relevance of the above findings. Randomized clinical trials are underway comparing resection versus observation in metastatic breast and colon cancer with asymptomatic primary tumours. CONCLUSIONS In depth knowledge of how surgical intervention alters the tumour-host-metastasis communicating ecosystems could have important implications for clinical decision making in patients with synchronous metastatic disease and for the design and timing of multimodality treatment strategies.

Abstract
There are still debates regarding the appropriate primary treatment policy for asymptomatic primary colorectal lesions in cases of unresectable metastatic colorectal cancer. Even though there are patients with asymptomatic primary tumors when starting chemotherapy, those patients may still undergo surgery due to complications related to primary tumors in the middle of chemotherapy; therefore, controversy exists regarding surgical resection of primary colorectal lesions in cases where symptoms are absent when making a diagnosis. Thus, based on the published literature, we discuss opinions that prefer first-line surgery for primary tumors as well as opinions favoring first-line chemotherapy for treating unresectable synchronous metastatic colorectal cancer. Although the upfront chemotherapy including targeted agents is suggested as an effective treatment in recent years, the first line surgery has been a preferred treatment for decades. The first line surgery is beneficial to prolong the survival duration given the retrospective analysis of randomized trial data. So far, no prospective comparison study has only focused on the first-line treatment modality; thus, future clinical studies focusing on the survival duration and the quality of life should be performed as soon as possible. Furthermore, at this point, multidisciplinary team approaches would be helpful in finding the appropriate therapy. Regardless of symptoms, the performance status and the tumor burden should be taken into consideration as well. In case of surgical resection, minimally invasive surgery, such as laparoscopic surgery, is recommended.

Abstract
Although major progress has been achieved in the treatment of advanced colorectal cancer (CRC) with the employment of antiangiogenic agents, several questions remain on the use of these drugs in older patients. Since cardiovascular, renal and other comorbidities are common in the elderly, an accurate assessment of the patients’ conditions should be performed before a treatment decision is made. Since most CRC patients enrolled in clinical trials testing antiangiogenic drugs were aged < 65 years, the efficacy and tolerability of these agents in elderly patients has not been adequately explored. Data suggest that patients with advanced CRC derive similar benefit from bevacizumab treatment regardless of age, but the advantage of other antiangiogenic drugs in the same class of patients appears more blurred. Literature data suggest that specific antiangiogenic-related toxicities such as hypertension or arterial thromboembolic events may be higher in the elderly than in the younger patients. In addition, it should be emphasized that the patients included in the clinical studies discussed herein were selected and therefore may not be representative of the usual elderly population. Advanced age alone should not discourage the use of bevacizumab. However, a careful patients’ selection and watchful monitoring of toxicities are required to optimize the use of antiangiogenics in this population.

Abstract
BACKGROUND The start of chemotherapy usually requires a delay of about 4 weeks after surgical resection of colorectal cancer. However, there is no evidence for the required length of this delay interval. In addition, there is a chance that a patient may die because postoperative chemotherapy was not started soon enough and a metastatic tumor was able to develop rapidly. We therefore conducted a pilot study to determine the safety and feasibility of an early start of chemotherapy after the resection of colorectal cancer with distant metastases. METHODS Five patients were enrolled. They received XELOX therapy (130 mg/m2 of oxaliplatin on day 1 plus 1,000 mg/m2 of capecitabine twice daily on days 1 to 14) on the 7th postoperative day and XELOX + bevacizumab (7.5 mg/kg of bevacizumab on day 1) after the 2nd cycle of chemotherapy. RESULTS Five patients underwent open surgery. The procedures included right hemicolectomy in 1 patient, sigmoidectomy in 2 patients, high anterior resection in 1 patient, and Hartmann procedure in 1 patient. All patients started chemotherapy on postoperative day 7. The median number of cycles of chemotherapy was 11 (8 to 22). No postoperative complications were observed. The tumor reduction rate was 44.3% (32.0 to 66.6%). Progression-free survival was 10.3 months. CONCLUSIONS An early start of chemotherapy after surgery is feasible and safe. These findings suggest possible changes in the start time of chemotherapy after surgery in the future. We have already started a new phase II trial to confirm the effects of the early start of chemotherapy after surgery. TRIAL REGISTRATION UMIN000004361.
