To compare clinical and treatment characteristics and outcomes in locally advanced anal cancer, a potentially curable disease, in patients referred from a public or private hospital. We retrospectively reviewed 112 anal cancer patients from a public and a private hospital who received definitive chemoradiotherapy at the same cancer center between 2004 and 2013. Tumor stage, radiotherapy delay, radiotherapy duration, and unplanned treatment breaks ≥10 days were compared using t-test and χ(2) test. Overall survival (OS), disease free survival (DFS), and colostomy free survival (CFS) were examined using the Kaplan-Meier method and compared with the log-rank test. Cox proportional hazard models for OS and DFS were developed. The follow-up was 14.9 months (range, 0.7-94.8 months). Public hospital patients presented with significantly higher clinical T stage (P<0.05) and clinical stage group (P<0.05), had significantly longer radiotherapy delays (P<0.05) and radiotherapy duration...
Patients' preferences for low rectal cancer surgery
Ejso, 2008
Aim: To elicit surgery preferences of patients who have experience with either low anterior resection (LAR) or abdominoperineal resection (APR) and its outcomes, to support decision-making in future patients with resectable rectal cancer. Methods: One hundred and twenty-two patients were interviewed. Surgery preference was assessed in two ways. In the treatment trade-off method, the certainty of a stoma was hypothetically weighed against the risk of incontinence. In the time trade-off method, remaining life expectancy was traded off to avoid a permanent stoma or faecal incontinence. Results: To avoid APR, LAR patients accepted a much higher risk of incontinence than APR patients. In fact, 71% of the LAR patients chose LAR if they would certainly suffer monthly incontinence, and still 32% if they would certainly suffer daily incontinence. Nevertheless, APR patients would give up less remaining life years to be without a permanent stoma than LAR patients to be without monthly incontinence. Conclusions: Most patients preferred LAR above APR, even if LAR involved a risk of faecal incontinence. This seems to justify that LAR, if surgically possible, is performed in the first instance. However, since APR patients could live well with a permanent stoma, we recommend clearly informing patients before surgery about the surgical options and their potential outcomes.
Evaluation of the Rectal Cancer Patient Decision Aid: A Before and After Study
Diseases of the colon and rectum, 2016
In rectal cancer surgery, low anterior resection and abdominoperineal resection have equivocal impact on overall quality of life. A rectal cancer decision aid was developed to help patients weigh features of options and share their preference. The aim of this study was to evaluate the effect of a patient decision aid for mid to low rectal cancer surgery on the patients' choice and decision-making process. A before-and-after study was conducted. Baseline data collection occurred after surgeon confirmation of eligibility at the first consultation. Patients used the patient decision aid at home (online and/or paper-based formats) and completed post questionnaires. This study was conducted at an academic hospital referral center. Adults who had rectal cancer at a maximum of 10 cm proximal to the anal verge and were amenable to surgical resection were considered. Those with preexisting stoma and those only receiving abdominoperineal resection for technical reasons were excluded from ...
BMC public health, 2013
Background: The incidence of human papillomavirus (HPV)-associated anal cancer is increasing in men who have sex with men (MSM). Screening for the presumed cancer precursor, high-grade anal squamous intraepithelial lesions (HSIL) in a manner analogous to cervical cancer screening has been proposed. Uncertainty remains regarding anal HPV natural history and the role of anal cytology and high-resolution anoscopy (HRA) as screening tests. Well-designed cohort studies are required to address these issues. Methods/design: The SPANC study is a prospective study of the epidemiology of low-risk and high-risk anal HPV infection and related cytological and histological abnormalities in HIV-negative and HIV-positive homosexual men aged 35 years and over. The study aims to recruit 600 men from community-based settings in Sydney, Australia. There are six study visits over three years. At the first five visits men undergo a digital ano-rectal examination (DARE), an anal "Papanicolaou" (Pap) test for HPV detection, genotyping and anal cytology, followed by HRA and directed biopsy of any visible abnormalities. The men also complete a behavioural questionnaire before each visit. Questions include a detailed history of sexual behaviour, of anal symptoms, possible anal cancer risk factors and validated quality of life and psychosocial questions. Questionnaires are also completed 2 weeks and 3 months following the provision of test results and include questions on participant experience during the procedure and post-procedure symptoms, including pain and bleeding in addition to quality of life/ psychosocial outcomes.
Evaluation of anal function after surgery for rectal cancer
Journal of surgical oncology, 2000
Sphincter-saving surgical procedures for rectal cancer have been legitimized if executed respecting the criteria of oncological radicalness. Our objective was to evaluate anal sphincteric continence after rectal cancer surgery. A detailed questionnaire regarding continence was administered to 3 groups of patients. Group 1 was composed of 9 patients treated with a higher (>4 cm), stapled colorectal anastomosis; the 9 group 2 patients were treated with a low (< or =4 cm), stapled colorectal anastomosis; the 9 group 3 patients underwent coloanal anastomosis. The results were evaluated about 3 years after surgery. Continence was excellent in group 1 and very good in group 2. However, in group 3, we observed diminished gas/feces discrimination, reduced ability to postpone evacuation, and increased soiling and perianal rash. Anal sphincteric continence was better after surgery with a high or low colorectal anastomosis than after coloanal anastomosis.
The bottom line: Outcomes after conservation treatment in anal cancer
Australasian Radiology, 2006
At the Department of Radiation Oncology, Westmead Hospital, between 1980 and 2000, 60 patients with squamous cell carcinoma of anal canal or margin (including 15 with Stage IIIA or IIIB) were treated radically; 55 received chemoradiation (89% were prescribed mitomycin C and 5-fluorouracil). Five-year overall survival was 64% (95% confidence interval (CI): 48-79%), with a median survival of 9.75 years (median follow up 5.6 years, range 5 months to 22.5 years). Ten patients have died of disease. At 2 years the local control rate was 86%, and colostomy-free survival was 83%. Relapse after 2 years was uncommon. Tumour size was the main factor driving outcomes, especially survival. Patients with larger tumours (T > 4 cm) had a hazard ratio for survival of 5.7 (95% CI: 1.8-17). Fourteen (24%) patients experienced treatment interruptions as a result of acute toxicity, including one death from neutropoenic sepsis. Seven (12%) patients, in total, experienced one or more late toxicities, grade 3 or above, including four women (all postmenopausal) who developed a radiation-induced bone injury. Most patients with anal cancer can expect to retain a functional sphincter after chemoradiation/radiation. Further studies are in progress to determine the optimal chemoradiation protocol.
Personalised surgery for rectal tumours: The patient's opinion counts
Supportive Care in Cancer, 1997
In recent times there have been many important changes in the surgical management of rectal cancer. The general thrust of these changes has been towards a less invasive approach with preservation of intestinal continuity and avoidance of the psychological sequelae of a stoma. It is also becomming increasingly apparent that profound sexual and autonomic dysfunction can be associated with abdominoperineal resection. This paper highlights these issues and the conflict between performing an adequate oncological proceedure and reducing the incidence of postoperative psychological morbidity. It outlines the great changes there have been in surgical technique and their relevance to psychological problems after surgery for rectal cancer. The need for auditing psychological morbidity when assessing the outcome of surgical series is emphasised, as is the importance of involving the patient in the medical decision making.
The results of 21-year experience of treating anal squamous cell carcinomas
Turkish Journal of Surgery, 2014
Anal squamous cell carcinomas are one of the rare cancer types. Due to the developments in the past 35 years, surgery is no longer the first treatment of choice. The aim of this study was to retrospectively examine the outcomes of 24 patients treated in a single center in the last 21 years in terms of applied treatment, local relapse, distant metastasis, post-treatment complications, and survival. Material and Methods: Data obtained from 24 anal squamous cell carcinoma patients, who were treated in Ankara Oncology Research and Education Hospital between 1990 and 2010, were retrospectively evaluated. Results: Of the 24 patients, 16 had anal canal squamous cell carcinoma and eight had perianal squamous cell carcinoma. All of the patients with anal canal squamous cell carcinoma (n=16) received chemoradiotherapy. Three of these patients who did not respond to treatment, underwent abdominoperineal resection. The patients with perianal squamous cell tumors were treated by local excision. During the follow-ups, seven patients experienced local relapse, and one patient had distant organ metastasis. Only one patient died. Five-year disease free survival rate was found as 66%. Conclusion: Our findings suggest that the first alternative in the treatment of anal squamous cell tumors should be chemoradiotherapy; and surgery seems to be the appropriate approach for the non-responsive and relapsing cases.
