RESUMEN
OBJECTIVE: To evaluate treatment outcome in a large population-based cohort of patients with anal cancer treated according to Nordic guidelines. MATERIAL: Clinical data were collected on 1266 patients with anal squamous cell carcinoma diagnosed from 2000 to 2007 in Sweden, Norway and Denmark. 886 of the patients received radiotherapy 54-64Gy with or without chemotherapy (5-fluorouracil plus cisplatin or mitomycin) according to different protocols, stratified by tumor stage. RESULTS: High age, male gender, large primary tumor, lymph node metastases, distant metastases, poor performance status, and non-inclusion into a protocol were all independent factors associated with worse outcome. Among patients treated according to any of the protocols, the 3-year recurrence-free survival ranged from 63% to 76%, with locoregional recurrences in 17% and distant metastases in 11% of patients. The highest rate of inguinal recurrence (11%) was seen in patients with small primary tumors, treated without inguinal irradiation. CONCLUSIONS: Good treatment efficacy was obtained with Nordic, widely implemented, guidelines for treatment of anal cancer. Inguinal prophylactic irradiation should be recommended also for small primary tumors.

PURPOSE: To examine the prevalence and severity of faecal incontinence amongst anal cancer survivors after chemoradiotherapy. MATERIAL AND METHODS: Anal cancer survivors from a complete, unselected, national cohort, minimum 2-years follow-up, were invited to a cross-sectional study. The St. Mark's incontinence score was used to evaluate occurrence and degree of faecal incontinence the last four weeks. The results were compared to age- and sex-matched volunteers from the general population. RESULTS: Of 199 invited survivors and 1211 volunteers, 66% and 21%, respectively, signed informed consent. The survivors had significantly higher St. Mark's score than the volunteers (mean 9.7 vs. 1.1, p<0.001). Incontinence of stool of any degree was reported by 43% vs. 5% (OR 4.0, CI 2.73-6.01), and urgency was reported by 64% vs. 6% (OR 6.6, CI 4.38-9.90) of the survivors and volunteers, respectively. Only 29% of those with leakage of liquid stool used constipating drugs. Survivors of locally advanced tumours had a higher incontinence score (p<0.01). CONCLUSIONS: Moderate to severe faecal incontinence is common amongst anal cancer survivors. Post-treatment follow-up should include the evaluation of continence, and incontinent survivors should be offered better symptom management and multidisciplinary approach if simple measures are insufficient.

BACKGROUND: Chemoradiotherapy is an effective treatment for anal cancer, yet from follow-up many survivors seem to suffer from late effects. Data of long-term health-related quality of life (HRQOL) in anal cancer survivors are limited, and there is a growing interest in cancer survivorship. MATERIAL AND METHODS: A national cohort of all anal cancer survivors treated with curative chemoradiotherapy in 2000-2007 was invited to a cross-sectional study. Of 199 eligible survivors, 128 (64%) returned the questionnaires, the median time since diagnosis was 66 months. The median age was 61 years and 79% were women. HRQOL was evaluated with EORTC questionnaires QLQ-C30 and QLQ-CR29, and neurotoxicity with the Scale of Chemotherapy-Induced Neurotoxicity. An age- and sex-matched reference group of volunteers (n = 269) not treated for pelvic cancer answered the same questionnaires. Results from QLQ-C30 of the reference group were compared to Norwegian and Dutch normative data. RESULTS: The mean scores of anal cancer survivors were poorer compared to volunteers and normative data. Anal cancer survivors reported significant impairment of function, especially social and role function, compared to the volunteers (difference ≥ 20 points, p < 0.001). Survivors had markedly increased scores for fatigue, dyspnoea, insomnia and diarrhoea (difference ≥ 15 points, p < 0.001). The global quality of life was significantly reduced (difference 15 points, p < 0.001). Anal cancer survivors had increased stool frequency, more buttock pain, flatulence, faecal incontinence, impotence (males), dyspareunia and reduced sexual interest (females) (difference ≥ 15 points, p < 0.001). There was increased frequency of tinnitus in survivors treated with cisplatin-based chemotherapy (p = 0.004). CONCLUSIONS: Survivors after chemoradiotherapy for anal cancer have significant long-term impairment of HRQOL. Reduced social, role and sexual function, and increased diarrhoea, incontinence for gas and stools, and buttock pain were commonly reported. Increased awareness of this may lead to better management of late effects and better care for cancer survivors.

PURPOSE: To evaluate treatment results, elucidate whether national guidelines were followed, and identify areas demanding further treatment optimization. METHODS AND MATERIAL: Between July 2000 and June 2007, 328 patients were treated with curatively intended chemoradiotherapy (CRT) for nonmetastatic squamous cell carcinoma of the anal region, according to national treatment guidelines based on tumor stage. RESULTS: Complete response after CRT was obtained in 87% of patients, rising to 93% after salvage surgery. Chemotherapy, elective irradiation of the groin and salvage surgery were performed to a lesser extent in elderly patients, mainly because of frailty and comorbidity. Recurrence occurred in 24% of the patients, resulting in a 3- and 5-year recurrence-free survival (RFS) of 79% and 74%, respectively. Locoregional recurrences dominated, most commonly in the primary tumor site. Recurrence was treated with curative intent in 45% of the cases. The 3- and 5-year overall survival were 79% and 66%, and cancer-specific survival (CSS) were 84% and 75%, respectively. The risk of adverse outcome increased significantly with more locally advanced tumors and for male gender in multivariable analyses for RFS and CSS. CONCLUSIONS: The treatment results are in accordance with similar cohorts. The primary treatment control rate was high, but there was a significant risk of locoregional recurrence in advanced tumors. The loyalty to national guidelines was broad, although individual adjustments occurred. However, caution to avoid toxicity must not lead to inadequate treatment. Male gender seems to have inferior outcome.

Two consecutive studies have evaluated the efficacy of oxaliplatin combined with the Nordic bolus schedule of 5-fluorouracil and folinic acid as first-line treatment in metastatic non-resectable colorectal cancer. One hundred and twelve patients were followed after end of first-line treatment and any secondary therapy registered. Fifty-three patients (47%) did not receive second-line irinotecan-based chemotherapy. The main reason was too poor performance status (59%). These patients had a median survival of only 1.7 months after progression of first-line therapy. The best predictive factors at start of first-line chemotherapy for receiving later second-line chemotherapy were performance status and alkaline phosphatase level. Fifty-nine patients (53%) received irinotecan-based second-line therapy. Four (7%) patients had a partial response, and 28 (52%) had stable disease. Median progression-free survival after second-line chemotherapy was 4.1 months and median survival 9.5 months. Median survival after first-line chemotherapy and secondary liver surgery was 34 months and five-year disease-free survival 8%. Survival among patients receiving both first- and second-line chemotherapy was 20.8 months, but only 8.9 months in patients not receiving second-line irinotecan-based chemotherapy. Poor performance status or elevated alkaline phosphatase level at start of first-line chemotherapy predicts whether second-line chemotherapy will be given or not.

Radiation therapy for abdominal recurrence of colon cancer is rarely an option due to subsequent bowel injury. Our case is a woman who underwent resection for a large retroperitoneal recurrence of caecal cancer. Tumour deposits encasing the iliac vessels had to be left behind. A silicone breast prosthesis for displacement of the abdominal content was implanted, allowing postoperative irradiation with 50 Gy. The prosthesis was removed once radiotherapy was accomplished; tumour regression was then complete. Complications are described, so are indications for surgical management of local recurrences of colonic origin as well as technical aspects of abdominal implantation of displacing prostheses. At follow-up after eighteen months the patient has no signs of enteropathy, she enjoys a good quality of life, and she is free of disease. Still, her prognosis is considered uncertain.
