BACKGROUND: Gastrointestinal carcinomas are genomically complex cancers that are lethal in the metastatic setting. Whole-genome and transcriptome sequencing allow for the simultaneous characterization of multiple oncogenic pathways. METHODS: We report 3 cases of metastatic gastrointestinal carcinoma in patients enrolled in the Personalized Onco-Genomics program at the BC Cancer Agency. Real-time genomic profiling was combined with clinical expertise to diagnose a carcinoma of unknown primary, to explore treatment response to bevacizumab in a colorectal cancer, and to characterize an appendiceal adenocarcinoma...

HER2 gene amplifications and activating mutations in the HER2 receptor tyrosine kinase are present in 4% of metastatic colorectal cancers (mCRCs). HER2-targeted therapy is not standard of care, although preclinical and clinical data suggest that patients with HER2 amplifications and/or HER2-activating mutations may benefit from HER2-directed therapy. HER2 amplifications and activating mutations have also been implicated in resistance to anti-epidermal growth factor receptor-based therapy. This report describes a patient with KRAS, NRAS, and BRAF wild-type mCRC who experienced disease progression on first-line treatment with FOLFIRI and cetuximab after only 5 months, and subsequently experienced progression on second-line treatment with capecitabine and oxaliplatin plus bevacizumab after 2 months with significant functional decline...

We report a long-term survivor of colorectal cancer who underwent aggressive, frequent resection for peritoneal recurrences. A 58-year-old woman was diagnosed with descending colon cancer. Resection of the descending colon along with lymph node dissection was performed in September 2006. The pathological findings revealed Stage IIA colorectal cancer. The following peritoneal recurrences were removed: two in July 2007, two in the omental fat and two in the pouch of Douglas in June 2008 resected by low anterior resection of the rectum, one in the uterus and right ovarian recurrence resected via bilateral adnexectomy and Hartmann's procedure in May 2011, and one in the ascending colon by partial resection of the colon wall in December 2011...

Because of its tumor-suppressive effect, interferon-based therapy has been used for the treatment of melanoma. However, limited data are available regarding the antitumor effects of pegylated interferons, either alone or in combination with approved anticancer drugs. We report that treatment of human WM-266-4 melanoma cells with peginterferon beta-1a induced apoptotic markers. Additionally, peginterferon beta-1a significantly inhibited the growth of human SK-MEL-1, A-375, and WM-266-4 melanoma xenografts established in immunocompromised mice...

Bevacizumab is an important component in the treatment of metastatic colorectal cancer when used with 5-fluorouracil, leucovorin and oxaliplatin or irinotecan. As a molecular target agent, it is considered to be less toxic than traditional chemotherapy; however, bevacizumab has been shown to cause serious, life-threatening adverse effects. The following report describes a case of bevacizumab-associated pulmonary embolism with simultaneous gastrointestinal perforation in a patient with stage IV adenocarcinoma of the descending colon...

BACKGROUND: Six months of oxaliplatin-based adjuvant chemotherapy is standard of care for radically resected stage III colon cancer and an accepted option for high-risk stage II. A shorter duration of therapy, if equally efficacious, would be advantageous for patients and Health-Care Systems. PATIENTS AND METHODS: TOSCA ['Randomized trial investigating the role of FOLFOX-4 or XELOX (3 versus 6 months) regimen duration and bevacizumab as adjuvant therapy for patients with stage II/III colon cancer] is an open-label, phase III, multicenter, noninferiority trial randomizing patients with high-risk stage II or stage III radically resected colon cancer to receive 3 months (arm 3 m) versus 6 months (arm 6 m) of FOLFOX4/XELOX...

BACKGROUND: Hepatic artery infusion (HAI) chemotherapy is an effective regional therapy for unresectable colorectal liver metastases (U-CRLM).1 (,) 2 One of its limitations is the need for a laparotomy, which can delay the use of systemic therapy.3 Here, we describe a purely robotic technique for placement of an HAI pump (Fig 1). PATIENT: A 62-year-old male presented with a symptomatic ascending colon cancer and multiple bilobar unresectable liver metastases. He underwent laparoscopic right colectomy followed by six cycles of FOLFOXIRI and bevacizumab with stable disease by RECIST (Response Evaluation Criteria in Solid Tumors) criteria, and also underwent robotic HAI pump placement...

INTRODUCTION: The prognostic outcome following progression after palliative first-line treatment for patients suffering from metastatic colorectal adenocarcinoma is generally poor. Long-term relapse-free survival with palliative second-line treatment may be achieved in only a limited number of individual cases. CASE REPORT: A 37-year-old patient presented with bilobar liver metastases of colon cancer confirmed by histology with wild-type K-RAS (exon 2). Due to progressive disease after eight cycles of first-line therapy with FOLFIRI plus cetuximab, second-line chemotherapy with modified FOLFOX4 (mFOLFOX4) plus bevacizumab was initiated...
