Colon cancer is the third most common cause of cancer diagnosed in the United States, and the second leading cause of cancer death. Although rates of the disease have been going down in recent years, results can be further improved. About 90% of people whose colon cancer is caught before it has spread to nearby lymph nodes or organs survive more than 5 years after diagnosis. However, only 10% of patients whose cancer has spread to distant parts of the body survive 5 years. Diagnosis at an early stage aims to reduce the incidence of tumors in an advanced stage and hence mortality. ⋯ The American Cancer Society has added two new screening methods, CT colonography, also known as virtual colonoscopy, and stool DNA tests to the list of options. A small revolution in screening for colon cancer is in the making. The availability of these less invasive tests should increase the number of people who undergo regular screening.

Surgical resection of rectal cancer is associated with a high pelvic recurrence rate. Preoperative large-fraction radiotherapy (RT) with a short interval after local excision has been associated with a significant improvement in locoregional recurrence rates and overall survival, but with high rates of toxicity. We here present the results of our combined-modality treatment protocol for patients with locally advanced rectal cancer. ⋯ Our results suggest that our combined-modality treatment protocol is well tolerated and achieves high locoregional control in this unselected population. The overall survival results are also encouraging. Further studies are required to confirm the toxicity profile and survival results of this regimen.

The aim of the study was to determine the incidence of venous thrombosis in cancer patients with central venous catheters inserted perioperatively. ⋯ Cancer patients have a high central venous catheter-related thrombosis risk perioperatively despite prophylactic anticoagulation. Color Doppler sonography is a rapid and noninvasive technique and it is accurate in the diagnosis of venous thrombosis. Early detection of venous thrombosis is important to prevent the systemic and fatal complication of the thrombosis.

Review Meta Analysis
Use of trastuzumab in HER2-positive metastatic breast cancer beyond disease progression: a systematic review of published studies.
Trastuzumab, a humanized monoclonal antibody directed against the extracellular domain of ErbB, has determined clinical benefit for women affected by metastatic or early stage HER2-positive breast cancer and never previously treated with trastuzumab. Trastuzumab is generally used as first-line treatment of HER2+ metastatic breast cancer and is currently administered beyond progression even without clear evidence supporting such clinical practice. In fact, HER2-positive metastatic breast cancer has a high risk of progressing after first-line therapy, and second-line treatments vary. The aim of the study was to investigate by a systematic review the efficacy of trastuzumab-based treatments beyond progression in HER2-positive metastatic breast cancer. ⋯ The added value of the present study has been to provide a quantitative summary measure of time to progression which can be used for comparisons between current and future available regimens.

The aggressiveness of cancer care near the end of life and the consumption of opioids are potential indicators of quality of care in palliative and end-of-life settings. The purpose of this article is to present a retrospective analysis regarding these themes and the adopted procedures to improve quality of care. ⋯ To reduce the administration of chemotherapy near the end of life, we introduced the palliative prognostic score, to be administered to all advanced cancer patients with performance status of at least 2. To evaluate the effectiveness of analgesics and to reduce the cases of undertreatment of cancer pain, we adopted, in addition to the numerical rating scale, Cleeland's Pain Management Index. We are convinced that attempts to improve the quality of care can be achieved by the collaboration of all health professionals, patients and care givers.
