A case of local recurrence of rectal cancer was successfully treated by UFT combined with two-route CDDP chemotherapy under the AT-II induced hypertension. UFT (600 mg/day) was orally administered every day. CDDP (75 mg/m2) was infused into the right internal iliac artery via subcutaneously grafted Infuse-a-port under hypertensive state induced by the AT-II (3 micrograms/min). Sodium thiosulfate was intravenously given to protect the CDDP induced nephrotoxicity. The recurrence tumor palpated by digital examination and revealed by MRI disappeared after the fourth two-route CDDP chemotherapy. The serum CEA level elevated before the treatment also normalized. This combined chemotherapy was considered to be an effective measure to cure the local recurrence of rectal cancer.

The associations between colorectal cancer risk and several chronic illnesses, operations, and various medications were examined in 715 colorectal cancer cases and 727 age/sex-matched controls in data derived from a large, comprehensive, population-based study of this cancer conducted in Melbourne, Australia. There was a statistically significant deficit among cases of hypertension, heart disease, stroke, chronic chest disease, and chronic arthritis and a statistically significant excess of "hemorrhoids" among cases, and all of these differences were consistent for both colon and rectal cancer and for both males and females. Although no statistically significant differences were found for other cancers, there were twice as many breast cancers among cases (16) than among controls and also there were 9 uterine cancers among cases and only 2 among controls. There was a statistically significant deficit among cases in the use of aspirin-containing medication and vitamin supplements, and this was consistent for both colon and rectal cancer and for both males and females. There was a statistically significant excess of large bowel polypectomy among cases. The modeling of these significant associations simultaneously in a logistic regression equation indicated that hypertension, heart disease, chronic arthritis, and aspirin use were each independent effects and consistent for both colon and rectal cancer for both males and females and also that these effects were independent of dietary risk factors previously described in the Melbourne study. The possible relevance of these findings towards an understanding of colorectal cancer risk and etiology is discussed.

This report presents the results of induced hypertension chemotherapy combined with radiotherapy for 44 advanced cancer patients (involving locoregional and/or remote recurrences). The lesions were 16 breast cancers, five soft tissue sarcomas, four lung cancers, four malignant lymphomas, three uterine cancers, two tongue cancers, and one parotid gland cancer, soft palate cancer, malignant thymoma, pancreatic cancer, vaginal cancer, urinary bladder cancer and rectal cancer each. The results, ive., eight complete remissions, 20 partial remissions and 16 cases of no change, were almost satisfactory.

For a patient with a tumour in the anal canal or with the inferior margin 5 cm or less from the anal verge an abdominoperineal rectal excision with permanent sigmoid colostomy is the only available treatment. The Turnbull-Cutait pull-through technique involved full mobilization of the rectum, complete eversion of the anorectal stump and pull-through of the colon, the excess of which was resected in the second stage of the operation, followed by suture of the colonic and rectal mucosa. Abdomino sacral resection has been practised by a few surgeons only. Abdominotransanal resection with sutured colo-anal sleeve anastomosis was the operation developed by Sir Alan Parks. In this operation the anorectal stump is not everted through the anus as in the Turnbull-Cutait operation. There has been a great revival of interest in low anterior resections with the introduction of the EEA instrument for stapling the colorectal anastomosis and there is still today a great enthusiasm for this technique. In an attempt to improve the results trial are going on at present to evaluate the importance of a J-configured neo-rectum constructed from the sigmoid or descending colon and stapled to the top of the anal canal or handsutured to the pectinate line after endoanal mucosectomy. Many patients with rectal carcinoma are old and often suffer from intercurrent diseases such as hypertension, diabetes etc. There is considerable postoperative complication. An abdominoperineal resection with a colostomy is by no means outdated for an ultralow or low sited rectal cancer.

It has been reported that allergy and other diseases may be related to colorectal cancer risk. The aim of this study was to perform a systematic analysis using information about medical histories specifically to see if there was any relation between allergies or other medical conditions and colorectal cancer risk. A multicentric case-control study was conducted in six Italian areas between 1992 and 1996 on 1225 incident cases of colon cancer, 728 cases of rectal cancer and 4154 controls comparable with cases according to sex and age group, admitted for acute conditions to the same network of hospitals where cases had been identified. Unconditional logistic regression models including terms for sex, age, study centre, years of education, body mass index, physical activity, smoking, history of colorectal cancer in first-degree relatives and energy intake were used to estimate the odds ratios (OR) of colon and rectal cancer according to history of allergy and other selected diseases. The OR for history of allergy was 0.88 (95% confidence interval, CI, 0.67-1.14) for colon and 0.64 (95% CI, 0.44-0.92) for rectal cancer, and the inverse association was stronger when allergy was diagnosed at age 35 years or more, or less than 10 years before the cancer diagnosis. No clear pattern emerged in strata of age and sex. History of other selected diseases, including hypertension and cholelithiasis, was not related to colon or rectal cancer risk, though there was a moderate increase in the risk of colon cancer (OR = 1.18, 95% CI, 0.66-2.14) in patients with a history of intestinal polyps. This study lends support to the hypothesis that allergic individuals may be at a lower risk of developing colorectal cancer.

An 80-year-old man with chronic bronchitis and hypertension was admitted with rectal cancer and cholecystolithiasis. Under general and epidural anesthesia, laparoscopic cholecysytectomy was performed with slightly elevated EtCO2. He underwent head-down tilt for laparoscopic rectectal amputation. Twenty five minutes after positioning, he developed ventricular tachycardia and died. Autopsy showed acute myocardial infarction super-imposed on the scar of lateral wall from old infarction. The laparoscopic operating techniques have become popular, but we do not know the safety limits of the pneumoperitoneal pressure and the angle of head-down tilt position. In our case, the cardiac event occurred 25 minutes after head-down tilt, and the head-down tilt position when combined with pneumoperitoneum may have a fatal influence on high-risk cardiac patients.

According to Orem, active participation in caring for self contributes to the behavior of self-care. Before an individual is able to care for oneself, however, many factors must be considered. This article is based on an alert, oriented 85-year old widow, known as EL, who was recently diagnosed with rectal cancer. With postoperative hypertension and sinus tachycardia, EL is having difficulty learning self-care. This article demonstrates a scenario where Orem's self-care deficit theory of nursing assisted in developing an effective plan of self-care for an elderly woman who underwent an ileostomy.

A Japanese man who died at age 86 had been followed since the age of 58, when he presented with hypertension of 150/95 mmHg. The patient remained socially active until he died suddenly of a ruptured thoracic aortic aneurysm, although he experienced angina pectoris in August 1974, and myocardial infarction was identified on electrocardiography in October 1974. He underwent operation for rectal cancer in 1987, and an abdominal aortic aneurysm 38mm in diameter was identified at that time. The patient underwent an operation for rupture of the abdominal aortic aneurysm in 1991. A thoracic aneurysm of 40 mm diameter was identified in 1995, and this expanded to 53 mm by 1997. Autopsy revealed a thoracic aortic aneurysm in the arch (8 x 5 x 5 cm) and descending aorta (7 x 7 x 8 cm). A large volume (2,080 ml) of bloody pleural fluid was present

Angiogenesis, a complex, coordinated process resulting in the assembly and maturation of new blood vessels, is critical for the growth of tumors. Several lines of evidence argue for angiogenesis inhibition in the treatment of colorectal cancer (CRC) : 1) angiogenesis (as measured by microvessel count), and the expression of pro-angiogenesis factors, such as vascular endothelial growth factor (VEGF), the key regulator of normal and pathological angiogenesis, have been reported to correlate with advanced disease and a worse prognosis ; 2) the expression of VEGF has been shown to correlate with RAS mutations, alterations in the APC-WNT signaling pathway, and overexpression of cyclo-oxygenase-2, which all are frequent in CRC ; 3) bevacizumab, a humanized anti-VEGF monoclonal antibody, is a potent inhibitor of tumor growth of various CRC cell lines in murine xenografts ; 4) the addition of bevacizumab to systemic chemotherapy has been shown to be significantly superior to chemotherapy alone in terms of objective tumor response rate, progression-free survival, and overall survival in patients with metastatic CRC, in the frontline, and more recently in the second-line setting, without worsening of chemotherapy-related toxicity. However, several potential specific adverse events, such as thrombosis, hemorrhages, proteinuria, arterial hypertension, and bowel perforations have been described. Whether the antitumoral efficacy of bevacizumab could be increased when combined to low-dose (metronomic) chemotherapy, or radiotherapy (in rectal cancer), is under development, as well other VEGF-targeted approaches (e.g., dominantnegative mutants, antisense oligonucleotides, antibodies directed against VEGF receptors (VEGFR), VEGFR tyrosine kinase inhibitors, soluble VEGFR,...), or other anti-angiogenesis agents (e.g., thalidomide, celecoxib, angiozyme...).

Type 2 diabetes mellitus shares risk factors for and has shown a positive association with colorectal cancer. Anthropometric measures (height, weight, and body mass index (weight (kg)/height (m)(2)) and metabolic abnormalities associated with insulin resistance syndrome (IRS) (abnormalities in measured blood pressure, high density lipoprotein (HDL) cholesterol, and total cholesterol) were prospectively evaluated for associations with incident colon (n = 227), rectal (n = 183), and colorectal (n = 410) cancers diagnosed between 1985 and 2002 in 28,983 Finnish male smokers from the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study. Cox proportional hazards models were used to calculate hazard ratios and 95% confidence intervals. In comparison with the lowest quintile, the highest quintile of body mass index was significantly associated with colorectal cancer (hazard ratio (HR) = 1.70, 95% confidence interval (CI): 1.01, 2.85; p-trend = 0.01), particularly colon cancer. Subjects with a cluster of three IRS-related conditions (hypertension, body mass index >/=25 kg/m(2), and HDL cholesterol level <40 mg/dl (<1.55 mmol/liter)), compared with those with fewer conditions, had a significantly increased risk of colorectal cancer (HR = 1.40, 95% CI: 1.12, 1.74), particularly colon cancer (HR = 1.58, 95% CI: 1.18, 2.10), but not rectal cancer. These results support the hypothesis that the significant association observed between IRS-defining metabolic abnormalities and colorectal cancer is determined primarily by adiposity.
