David Lam, Eugene Ong
INTRODUCTION: Krukenberg tumour (KT), which represents carcinoma in the ovary, is an uncommon manifestation of metastatic colorectal cancer. It is associated with poor prognosis and a high incidence of peritoneal metastatic disease. PRESENTATION OF CASE: The authors present a case of a 51-year-old female who had a symptomatic, metachronous right ovarian KT diagnosed 12 months after her initial resection. Surgery was performed to excise the 23cm tumour as well as the contralateral ovary and isolated peritoneal disease, with an R0 resection achieved...

PURPOSE: About 30% of colorectal cancers (CRCs) present with acute symptoms. The adequacy of oncologic resections is a matter of concern since few authors reported that emergency surgery in these patients results in a lower lymph node harvest (LNH). In addition, emergency resections have been reported with a longer hospital stay and higher morbidity rate. We thus conducted a propensity score-matched analysis with the aim of investigating LNH in emergency specimens comparing with elective ones...

BACKGROUND: It is still under debate that whether stage IV colorectal cancer patients with unresectable metastasis can benefit from primary tumor resection, especially for asymptomatic colorectal cancer patients. Retrospective studies have shown controversial results concerning the benefit from surgery. This retrospective study aims to evaluate whether the site of primary tumor is a predictor of palliative resection in asymptomatic stage IV colorectal cancer patients. METHODS: One hundred ninety-four patients with unresectable metastatic colorectal cancer were selected from Sun Yat-sen University Cancer Center Database in the period between January 2007 and December 2013...

The role of surgery of the primary cancer and radiation in metastatic colorectal cancer (mCRC) is still controversial currently, and evidence implied that colon cancer (CC) and rectal cancer (RC) should be treated with difference. Hence we focused on metastatic rectal cancer (mRC) solely to compare the cancer cause-specific survival (CSS) of patients receiving varied treatments of the primary cancer: no treatment, surgery only, radiation only, and surgery plus radiation, based on the records of the Surveillance, Epidemiology, and End Results (SEER) database...

Secondary tumors of the ovary account for 10-25% of all ovarian malignancies. The most common tumors that give rise to ovarian metastases include breast, colorectal, endometrial, stomach, and appendix cancer. The correct diagnosis of secondary ovarian tumors may be challenging as they are not infrequently misdiagnosed as primary ovarian cancer, particularly in the case of mucinous adenocarcinomas. The distinction from the latter is essential, as it requires different treatment. Immunohistochemistry plays an important role in distinguishing primary ovarian tumors from extra-ovarian metastases and, furthermore, may suggest the primary tumor site...

Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) plays a pivotal role in the current treatment of peritoneal carcinomatosis (PC) from colorectal cancer (CRC). Since the first demonstration, benefits for patients and especially an increase in survival have been described. In recent years, feasibility, efficacy and safety of HIPEC have been improved and progress has been made in understanding its oncological mechanism. Areas covered: In this article, leading publications have been reviewed including clinical trials to describe the clinical presentation of PC due to CRC and present recent evidence of the CRS/HIPEC procedure...

BACKGROUND: Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported. PATIENTS AND METHODS: All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed...

INTRODUCTION: Thyroid metastases from colorectal cancer are uncommon and few cases are described in literature. CASE PRESENTATION: A 64-year-old female patient presented with an asymptomatic right cervical nodule with a rapid growth six years after sigmoidectomy for cancer and two years after resection of colorectal lung metastases. Increased CA 19.9 was identified and a thoracoabdominal CT scan revealed the onset of new metastatic bilateral pulmonary lesions. Neck ultrasonography showed a suspicious nodule in the right thyroid lobe, and Fine-needle Aspiration Cytology (FNAC) of the nodule lead to the diagnosis of colorectal cancer metastasis...

BACKGROUND: Adjuvant chemotherapy after resection of colorectal cancer (CRC) lung metastases may reduce recurrences and improve survival. We investigated the effects of adjuvant chemotherapy after curative resection of lung CRC metastases on prognosis. METHODS: We retrospectively reviewed records of our patients undergoing pulmonary metastasectomy from CRC between January 2000-March 2014. Data were analyzed with Kaplan-Meier survival analysis and Cox proportional hazards models...

OBJECTIVE: The role of surgery in metastatic colorectal cancer (mCRC) remains controversial. This study was performed to assess the impact of surgery on survival in metastatic colorectal cancer. MATERIALS AND METHODS: Information of mCRC patients diagnosed between January 1, 2004, and December 31, 2013, was retrieved from the Surveillance, Epidemiology, and End Results Program database. Patients were classified in three groups: patients undergoing resection of both primary and distant metastatic tumors (group 'PMTR'), patients receiving primary tumor resection alone (group 'PTR') and patients not undergoing any surgery (group 'No resection')...

BACKGROUND/AIMS: The identification of prognostic factors of metastatic development is one of the most important issues in colorectal cancer (CRC) research. The aim of this study was to determine the usefulness of colon tumor characteristics, including location, circumferential location, histological type, and histological grade, as predictors of metastases. MATERIALS AND METHODS: To identify potential predictors of CRC spread, we analyzed data of 191 patients who had undergone surgery for colon tumors...

OBJECTIVE: The use of PET CT for staging in cancer patients and the widespread use of MRI led to an increased incidence of incidental sellar mass detection. The imaging findings can be suggestive of a benign pituitary tumor but metastasis can never be completely ruled out with non-invasive work-up. Appropriate diagnosis of these sellar masses is critical as the treatment paradigm might change in the presence of a pituitary metastasis. Moreover, definitive tissue diagnosis might prevent unnecessary radiotherapy to the skull base or even the need for systemic treatment when benign pituitary disease is confirmed...

BACKGROUND: Reports show that selective internal radiation therapy (SIRT) may downsize inoperable liver tumors to resection or transplantation, or enable a bridge-to-transplant. A small-cohort study found that long-term survival in patients undergoing resection following SIRT appears possible but no robust studies on postsurgical safety outcomes exist. The Post-SIR-Spheres Surgery Study was an international, multicenter, retrospective study to assess safety outcomes of liver resection or transplantation following SIRT with yttrium-90 (Y-90) resin microspheres (SIR-Spheres(®); Sirtex)...

Colorectal cancer remains a leading cause of cancer-related death in Europe. Approximately one-quarter of patients have synchronous hepatic metastases and metachronous liver metastases occur in a further 30%. The scope of surgery in management of colorectal metastases has evolved to include selected patients with extra-hepatic disease for whom R0 resection is considered feasible; however, locoregional treatments are increasingly recognised as viable management options in those patients deemed unsuitable for surgery and there is an expanding body of evidence regarding their ability to achieve local control and increase progression-free survival in the liver...

Optical coherence tomography (OCT) is a real-time, cross-sectional optical imaging technology. It is analogous to ultrasonography, except that OCT uses light waves instead of sound waves, and can provide three-dimensional morphological images of living tissues with a micrometer resolution. Through the use of endoscopes, needles, catheters and laparoscopes, OCT has demonstrated tremendous imaging potential in tumor surgery. The current studies suggest that OCT has potential for clinical applications in the following fields of gastrointestinal tumor surgery: (1) Early tumor detection and diagnosis: OCT can distinguish differences between polyp tissue, normal tissue and malignant tissue...

BACKGROUND: Intensive follow-up after surgery for colorectal cancer is common practice but lacks a firm evidence base. OBJECTIVE: To assess whether or not augmenting symptomatic follow-up in primary care with two intensive methods of follow-up [monitoring of blood carcinoembryonic antigen (CEA) levels and scheduled imaging] is effective and cost-effective in detecting the recurrence of colorectal cancer treatable surgically with curative intent. DESIGN: Randomised controlled open-label trial...

BACKGROUND: In first-line wild-type (WT)-Kirsten rat sarcoma viral oncogene homologue (KRAS) metastatic colorectal cancer (mCRC), panitumumab (Pmab) improves outcomes when added to FOLFOX [folinic acid, 5-fluorouracil, and oxaliplatin] or FOLFIRI [folinic acid, 5-fluorouracil, and irinotecan]. However no trial has directly compared these combinations. METHODS: Multicentre, open-label study in untreated patients ≥ 18 years with (WT)-KRAS mCRC and multiple or unresectable liver-limited disease (LLD) randomised to either Pmab-FOLFOX4 or Pmab-FOLFIRI...

BACKGROUND: Venous thromoboembolism (VTE) is a frequent and burdensome complication of metastatic colorectal cancer (CRC). However, the epidemiology of VTE in patients with localized CRC after surgery in curative intent is incompletely understood. In this single-center observational cohort study, we investigate patterns of VTE risk in localized CRC, and define its relationship with baseline risk factors, adjuvant chemotherapy and CRC recurrence. METHODS: Five-hundred-sixteen patients with stage II/III CRC were included retrospectively at the time of surgery, and followed until the occurrence of VTE, CRC recurrence, or death (median age = 65...

BACKGROUND: Following primary surgical and adjuvant treatment for colorectal cancer, many patients are routinely followed up with blood carcinoembryonic antigen (CEA) testing. OBJECTIVE: To determine how the CEA test result should be interpreted to inform the decision to undertake further investigation to detect treatable recurrences. DESIGN: Two studies were conducted: (1) a Cochrane review of existing studies describing the diagnostic accuracy of blood CEA testing for detecting colorectal recurrence; and (2) a secondary analysis of data from the two arms of the FACS (Follow-up After Colorectal Surgery) trial in which CEA testing was carried out...
