BMC Cancer 2024; 24:374. [PMID: 38528456 DOI: 10.1186/s12885-024-12111-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 03/12/2024] [Indexed: 03/27/2024] Open
Abstract
BACKGROUND Chemo-radiotherapy with curative intent for anal cancer has high complete remission rates, but acute treatment-related gastrointestinal (GI) toxicity is significant. Toxicity occurs due to irradiation of surrounding normal tissue. Current radiotherapy requires the addition of large planning margins to the radiation field to ensure target coverage regardless of the considerable organ motion in the pelvic region. This increases the irradiated volume and radiation dose to the surrounding normal tissue and thereby toxicity. Online adaptive radiotherapy uses artificial intelligence to adjust the treatment to the anatomy of the day. This allows for the reduction of planning margins, minimizing the irradiated volume and thereby radiation to the surrounding normal tissue.This study examines if cone beam computed tomography (CBCT)-guided oART with daily automated treatment re-planning can reduce acute gastrointestinal toxicity in patients with anal cancer. METHODS/DESIGN The study is a prospective, single-arm, phase II trial conducted at Copenhagen University Hospital, Herlev and Gentofte, Denmark. 205 patients with local only or locally advanced anal cancer, referred for radiotherapy with or without chemotherapy with curative intent, are planned for inclusion. Toxicity and quality of life are reported with Common Terminology Criteria of Adverse Events and patient-reported outcome questionnaires, before, during, and after treatment. The primary endpoint is a reduction in the incidence of acute treatment-related grade ≥ 2 diarrhea from 36 to 25% after daily online adaptive radiotherapy compared to standard radiotherapy. Secondary endpoints include all acute and late toxicity, overall survival, and reduction in treatment interruptions. RESULTS Accrual began in January 2022 and is expected to finish in January 2026. Primary endpoint results are expected to be available in April 2026. DISCUSSION This is the first study utilizing online adaptive radiotherapy to treat anal cancer. We hope to determine whether there is a clinical benefit for the patients, with significant reductions in acute GI toxicity without compromising treatment efficacy. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05438836. Danish Ethical Committee: H-21028093.

Abstract
PURPOSE To investigate the effectiveness of physiotherapy interventions compared to control conditions on fecal incontinence (FI) and quality of life (QoL) following colorectal surgery. METHODS Electronic searches in English-language (Scopus, Web of Science, Embase, AMED, CENTRAL, CINAHL, MEDLINE, Ovid, and PEDro) and Chinese-language (CNKI, Wanfang Data) databases were conducted. Trials comparing physiotherapy interventions against control conditions and assessing FI and QoL outcomes were included in the review. RESULTS Ten trials were included. Meta-analysis revealed statistically significant improvements in lifestyle (0.54; 95% CI 0.03, 1.05; p = 0.04), coping behavior (MD 1.136; 95% CI 0.24, 2.04; p = 0.01), and embarrassment (0.417; 95% CI 0.14, 0.70; p = 0.00) components of QoL among individuals receiving pelvic floor muscle training (PFMT) compared with those receiving usual care (UC). Meta-analysis showed biofeedback to be significantly more effective than UC in enhancing anal resting pressure (ARP; 9.551; 95% CI 2.60, 16.51; p = 0.007), maximum squeeze pressure (MSP; 25.29; 95% CI 4.08, 48.50; p = 0.02), and rectal resting pressure (RRP; 0.51; 95% CI 0.10, 0.9; p = 0.02). Meta-analysis also found PFMT combined with biofeedback to be significantly more effective than PFMT alone for ARP (3.00; 95% CI 0.40, 5.60; p = 0.02), MSP (9.35, 95% CI 0.17, 18.53; p = 0.05), and RRP (1.54; 95% CI 0.60, 2.47; p = 0.00). CONCLUSIONS PFMT combined with biofeedback was more effective than PFMT alone, but both interventions delivered alone were superior to UC. Future studies remain necessary to optimize and standardize the PFMT parameters for improving QoL among individuals who experience FI following CRC surgery. REVIEW REGISTRATION This systematic review is registered in the PROSPERO registry (Ref: CRD42022337084).

Long-Term Patient-Reported Quality of Life of Anal Cancer Survivors Treated With Intensity Modulated Radiation Therapy and Concurrent Chemotherapy: Results From a Prospective Phase II Trial. Int J Radiat Oncol Biol Phys 2023; 117:434-445. [PMID: 37148982 DOI: 10.1016/j.ijrobp.2023.04.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/12/2023] [Accepted: 04/18/2023] [Indexed: 05/08/2023]
Abstract
PURPOSE Intensity modulated radiation therapy (IMRT) has confirmed its superiority in improving acute treatment-related toxicities in anal cancer, without compromising tumor control. However, the effect of IMRT on long-term quality of life (QOL) is poorly documented. The study prospectively evaluated the long-term patient-reported QOL after IMRT-based chemoradiation in anal cancer. METHODS AND MATERIALS Fifty-eight patients treated with IMRT and concurrent 5 fluorouracil/mitomycin-C were enrolled in the study. A prespecified secondary endpoint was prospective evaluation of long-term QOL. Fifty-four patients underwent QOL evaluation at baseline, after treatment, and during follow-up until 60 months, with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) scales and the Colorectal Cancer-Specific Quality Of Life Questionnaire (QLQ-CR29) scales. The QOL scores at baseline and posttreatment periods were compared. RESULTS For QLQ-C30, at 60 months, the mean scores of global health status, all functional scales, and all symptoms except diarrhea had improved, indicating normalization of QOL. Clinically and statistically significant improvements in the global health status (15.4; P = .003), role functioning (19.3; P = .0017), emotional functioning (18.9; P = .008), and social functioning (29.8; P ≤ .001) were observed. Diarrhea persisted as a concern over the years (P = .172). For European Organization for Research and Treatment of Cancer QLQ-CR29, rectal pain (-38.6; P = .001), mucous or blood discharge per rectum (-22.8; P = .005), and perianal soreness (-37.3; P ≤ .001) were improved both clinically and statistically. Clinically significant fecal leakage was reported by 16% of patients (5.6; P = .421). Volumes receiving 45 and 54 Gy were independent predictors for fecal incontinence. Clinically and statistically significant urinary incontinence occurred in 21% of patients (17.5; P = .014). Deterioration of dyspareunia was clinically significant (26.7; P = .099) at 60 months. CONCLUSIONS Compared with historical data, IMRT is associated with reduced long-term effects on QOL. The majority of patients treated with IMRT experienced clinically significant recovery of function and improvement in QOL over 5 years after completion of treatment. Specific toxicities such as chronic diarrhea, fecal incontinence, and urinary and sexual dysfunction were primarily responsible for deterioration of the long-term QOL. Future research aimed at reducing such toxicities is needed to further improve long-term QOL in anal cancer.

Nordic anal cancer (NOAC) group consensus guidelines for risk-adapted delineation of the elective clinical target volume in anal cancer. Acta Oncol 2023; 62:897-906. [PMID: 37504978 DOI: 10.1080/0284186x.2023.2240490] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 07/14/2023] [Indexed: 07/29/2023]
Abstract
Background: To date, anal cancer patients are treated with radiotherapy to similar volumes despite a marked difference in risk profile based on tumor location and stage. A more individualized approach to delineation of the elective clinical target volume (CTVe) could potentially provide better oncological outcomes as well as improved quality of life. The aim of the present work was to establish Nordic Anal Cancer (NOAC) group guidelines for delineation of the CTVe in anal cancer.Methods: First, 12 radiation oncologists reviewed the literature in one of the following four areas: (1) previous delineation guidelines; (2) patterns of recurrence; (3) anatomical studies; (4) common iliac and para-aortic recurrences and delineation guidelines. Second, areas of controversy were identified and discussed with the aim of reaching consensus.Results: We present consensus-based recommendations for CTVe delineation in anal cancer regarding (a) which regions to include, and (b) how the regions should be delineated. Some of our recommendations deviate from current international guidelines. For instance, the posterolateral part of the inguinal region is excluded, decreasing the volume of irradiated normal tissue. For the external iliac region and the cranial border of the CTVe, we agreed on specifying two different recommendations, both considered acceptable. One of these recommendations is novel and risk-adapted; the external iliac region is omitted for low-risk patients, and several different cranial borders are used depending on the individual level of risk.Conclusion: We present NOAC consensus guidelines for delineation of the CTVe in anal cancer, including a risk-adapted strategy.

Abstract
PURPOSE To analyze clinical outcomes of high-dose-rate (HDR) interstitial brachytherapy boost (ISBT) after external beam radiation therapy (EBRT) or chemoradiotherapy (CRT) for the treatment of anal canal cancers (ACC). METHODS AND MATERIALS A total of 78 patients with ACC were treated at our institution by ISBT. Local Control (LC), disease-free survival (DFS), overall survival (OS), colostomy-free survival (CFS) and toxicity rates were analyzed. RESULTS With a median followup (FU) of 59.8 months (95% CI [55.8-64.2]), six (7.7%) local recurrences with 2 patients (2.6%) having persistent disease at 3 months were observed. The 5-year rate of LC for the entire population was 92% [83-96%]. The 5-year DFS rate was 86% [76-93%]. The 5-year OS was 96% [88-99%]. In the univariate analysis, chemotherapy was significantly associated with morbidity grade ≥2. Late digestive toxicity grade ≥3 was reported in 8.9% patients, 1 patient underwent colostomy due to toxicity. The 5-year CFS rate was 88% [79-94%]. CONCLUSIONS HDR interstitial brachytherapy boost provide excellent rates of tumor control and colostomy-free survival with a favorable profile of GI toxicity. Continence in anal cancer survivors is a challenge and the boost technique must be discussed in a multidisciplinary approach as part of de-escalation treatments.

Abstract
PURPOSE To compare toxicity of radiotherapy (RT) with concomitant chemotherapy (CHT) in patients (pts) with anal cancer treated with simultaneous integrated boost (SIB) versus sequential boost (SeqB). METHODS Sixty-six patients were treated from 2007 to 2021. Thirty patients underwent to SeqB concurrent to CHT and 37 to SIB-group. Toxicity assessment has been considered in acute and in late toxicities for gastrointestinal (GI), genitourinary (GU), cutaneous (CU) districts, according to Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0. The Wexner scale among summary scoring systems has been used as a tool to measure fecal incontinence. The chi-square test for ordinal variables were used to evaluate the association between patient and treatment characteristics and acute or late severe toxicity. Univariable logistic regression models were fit to evaluate predictive factors associated with fecal incontinence. RESULTS Median follow-up was 61.5 months (IQR, 27.1-121.7 months) for all patients. Severe acute toxicity (≥ G2) was observed in 49 patients (74.2%). Late toxicity (≥ G2) occurred in 13 cases (19.6%). In assessment of cutaneous toxicity, there was also a significant reduction in ≥ G1 in SIB group with 29 patients (80.5%) vs SeqB group with 29 patients (96.6%) (p-value = 0.046). Of both groups 11 patients (16.6%) developed fecal incontinence, 8 (22%) in the SIB group and 3 (10%) in the SeqB. CONCLUSION SIB for anal cancer treatment results in reduced acute and late cutaneous toxicity compared to SeqB. According to our results the rate of other acute and late toxicities are low and comparable between the two groups.

Abstract
PURPOSE Patient-reported outcome (PRO) and National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) data for patients with squamous cell carcinoma of the anus (SCCA) treated with modern radiation therapy (RT) are lacking. The primary aim of this study was to report bowel and bladder PRO and NCI-CTCAE for patients with SCCA 1 year after RT. METHODS AND MATERIALS From 2015 to 2020, we included patients in a prospective Danish national study. Data were collected before treatment (PT) and 1 year after treatment (1Y) using NCI-CTCAE version 4.0, as well as European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and CR29. We evaluated the combined PRO scores according to the European Organisation for Research and Treatment of Cancer scoring guidelines, and classified changes according to score difference from PT to 1Y as no change (0-5), minor (5-10), moderate (11-20), and major (>20). Raw scores were reported as frequencies of each of the scores: Not at all, a little, quite a bit, and very much. RESULTS Of the 270 patients, 81% had complete data sets, including PT and 1Y answers. Functional mean scores were equal to a matched normal population cohort at PT and 1Y. From PT to 1Y, C30 scores were stable despite minor improvements in global health status/quality of life (7.3), emotional functioning (9.3), insomnia (8.0), and appetite loss (7.8). For questionnaire CR29, bowel and bladder symptoms and sore skin improved with minor change (6.2), and buttocks, anal, or rectal pain improved with moderate change (18.3). Flatulence worsened moderately (12.6), and fecal incontinence had minor worsening (7.8). Agreement between PROs and NCI-CTCAE was generally only fair to moderate, especially for quantitative symptoms, such as pain (κ = 0.25). CONCLUSIONS For patients with SCCA who underwent definitive RT, only a few patients had high scores (indicating quite a bit or very much frequency of bother) regarding bowel and bladder symptoms.

Abstract
PURPOSE Squamous cell carcinoma of the anus (SCCA) suffers a constant increase each year in the last decades. Recent studies suggested the possibility of local excision (LE) as an option for early-stage SCAC patients. This systematic review aims to summarize the available evidence on the comparison of LE vs. chemoradiotherapy (CRT) in the treatment of early SCCA patients. METHODS We conducted a literature review including MEDLINE/PubMed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database of Systematic Reviews through June 2022. MOOSE guidelines were followed. We used the methodological index for non-randomized studies (MINORS) tool to assess quality. Data on survival and procedure-associated costs were extracted. RESULTS Four retrospective studies including 3323 patients were included. They were all comparative retrospective cohort studies (three were registry-based studies, either NCDB or SEER) with a MINORS score of 16-19 points. Overall survival (OS) was comparable between LE and CRT patients in three studies, with a 5-year OS of 85.3-100% in LE patients and 85-91.6% in CRT patients. One study investigated cancer-specific survival (CSS) and reported similar 5-year CSS in LE (98%) and CRT patients (96%). One investigated progression-free survival (PFS) and did not report any statistically significant difference in 5-year PFS between LE (91%) and CRT patients (83%). Only one study considered the mean costs associated with the two approaches (29,210 USD with LE and 46,350 USD with CRT). CONCLUSIONS LE may potentially be considered a valid alternative to CRT for patients with early-stage SCAA. Results of prospective randomized long-term trials comparing LE with CRT are warranted to draw definitive conclusions and consider LE as a true cost-effective strategy for T1N0 SCCA with similar oncologic results offered by CRT, which-to date-remains the "gold standard."

Clin Colorectal Cancer 2022; 21:e226-e231. [PMID: 35753955 DOI: 10.1016/j.clcc.2022.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Revised: 03/08/2022] [Accepted: 03/11/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Patients with T2N0 squamous cell carcinoma of the anal canal (SCCA) have comprised less than 30% of patients enrolled in phase III clinical trials of curative-intent definitive chemoradiation. We aimed to evaluate treatment outcomes of these patients according to dose-intensity of chemoradiation. MATERIALS AND METHODS Retrospective multicenter study of patients with T2N0 SCCA, with the primary endpoint to compare the progression-free survival (PFS) of patients treated with full definitive chemoradiotherapy (f-CRT, CRT with 2 drugs) versus a nonstandard treatment (NST; radiotherapy only or CRT with 1 drug). Secondary outcomes were rates of complete response (CR), salvage surgery, and colostomy. PFS time was analyzed using the Kaplan-Meier method and differences in survival outcomes were assessed using the log-rank test and adjusted for prognostic covariates using a multivariable Cox regression model RESULTS: From March 2006 to January 2020, 74 patients were included. Most patients (n = 58; 78.4%) received f-CRT. In a median follow up time of 66.1 months, the unadjusted median PFS was 128.3 months (95% confidence interval [CI] 105.5-151.1) for f-CRT versus 74.1 months for NST (95% CI 45.8-102.4; P = .067). CR was achieved by 51 (87.9%) versus 11 (68.9%; P = .065) patients treated with f-CRT or an NST, respectively. Comparing f-CRT versus NST, the colostomy rates were higher for those treated with an NST: 5 (32.8%) versus 5 (9.5%; P = .019) CONCLUSION: For patients with T2N0 SCCA, f-CRT remains the standard treatment, offering higher CR and less likelihood of colostomy.

Abstract
Although rare, the rate of squamous cell carcinoma of the anus (SCCA) is rising globally. Most patients present with nonmetastatic disease and are curable with appropriate treatment, which has evolved significantly over the last several decades. Before the 1970s, SCCA was managed with radical surgery, resulting in a permanent colostomy. Researchers found that preoperative treatment with chemotherapy and concurrent radiation could achieve a pathologic complete response. After this observation, definitive therapy shifted from radical surgery to sphincter-preserving chemoradiation. Investigations into the necessity of chemotherapy and the optimal regimen found that chemotherapy with mitomycin-C and 5-fluorouracil is required for cure. Further studies evaluating the addition of induction or maintenance chemotherapy, monoclonal antibody therapy, or higher radiation doses have demonstrated no significant benefit to disease control. Advanced radiation delivery with intensity-modulated radiotherapy techniques is now considered the standard of care because of its prospectively determined, favorable acute toxicity profile compared with 3-dimensional conformal radiation. It is important to note that chemoradiation treatment response may be slow (up to 26 weeks) and should be assessed through serial clinical examinations. Today, surgical management of SCCA is reserved only for the lowest risk, early stage tumors or for recurrent/persistent disease. Current studies are evaluating radiation dose de-escalation in early stage disease and radiation dose escalation and the addition of immune checkpoint inhibitors in locally advanced cancers. In reviewing how and why modern-day treatment of SCCA was established, the objective of this report is to reenforce adherence to current treatment paradigms to assure the best possible outcomes for patients.

Abstract
Anal cancer is a relatively rare, mostly HPV-related cancer. The curative treatment consists of concurrent chemoradiation delivered with modern radiotherapy techniques. The prognosis for most patients with early localized disease is very favourable; however patients with locally advanced disease and/or HPV negative tumours are at higher risk of locoregional and distant treatment failure. Tailored approaches are presently being investigated to determine the most suitable regimen in terms of radiotherapy dose prescription, target volume selection, normal tissue avoidance, and combination therapy. Metastatic anal cancer is treated with chemotherapy aiming at prolonged survival. The role of immune therapy in the clinical setting is being investigated. There is little knowledge on the biology of anal cancer, and an urgent need for more clinical and translational research dedicated to this disease. In this article, the evidence-base for the current treatment is briefly reviewed, and perspectives on future research needs are high-lighted.

Abstract
BACKGROUND Squamous cell carcinoma of the anus (SCCA) is a rare malignancy with rising incidence, associated with human papilloma virus (HPV). Chemoradiotherapy (CRT) is the preferred treatment. The purpose was to investigate treatment failure, survival and prognostic factors after CRT. MATERIAL AND METHODS In this prospective observational study from a large regional centre, 141 patients were included from 2013 to 2017, and 132 were eligible for analysis. The main inclusion criteria were SCCA, planned radiotherapy, and performance status (ECOG) ≤2. Patient characteristics, disease stage, treatment, and treatment response were prospectively registered. Disease-free survival (DFS), overall survival (OS), and locoregional treatment failure after CRT were analysed. Hazard ratios (HRs) were estimated with Cox`s proportional hazards model. RESULTS Median follow-up was 54 (range 6-71) months. Eighteen patients (14%) had treatment failures after CRT; of these 10 (8%) had residual tumour, and 8 (6%) relapse as first failure. The first treatment failure was locoregional (11 patients), distant (5 patients), and both (2 patients). Salvage abdomino-perineal resection was performed in 10 patients, 2 had resections of metastases, and 3 both. DFS was 85% at 3 years and 78% at 5 years. OS was 93% at 3 years and 86% at 5 years. In analyses adjusted for age and gender, HPV negative tumours (HR 2.5, p = 0.024), N3 disease (HR 2.6, p = 0.024), and tumour size ≥4 cm (HR 2.4, p = 0.038) were negative prognostic factors for DFS. CONCLUSION State-of-the-art chemoradiotherapy for SCCA resulted in excellent outcomes, and improved survival compared with previous national data, with <15% treatment failures and a 3-year DFS of >80%.

Abstract
Prior to the 1980s, the primary management of localized anal cancer was surgical resection. Dr. Norman Nigro and colleagues introduced neoadjuvant chemoradiotherapy prior to abdominoperineal resection. Chemoradiotherapy 5-fluorouracil and mitomycin C afforded patients complete pathologic response and obviated the need for upfront surgery. More recent studies have attempted to alter or exclude chemotherapy used in the Nigro regimen to mitigate toxicity, often with worse outcomes. Reductions in acute adverse effects have been associated with marked advancements in radiotherapy delivery using intensity-modulated radiation therapy (IMRT) and image-guidance radiation delivery, resulting in increased tolerance to greater radiation doses. Ongoing trials are attempting to improve IMRT-based treatment of locally advanced disease with efforts to increase personalized treatment. Studies are also examining the role of newer treatment modalities such as proton therapy in treating anal cancer. Here we review the evolution of radiotherapy for anal cancer and describe recent advances. We also elaborate on radiotherapy's role in locally persistent or recurrent anal cancer.

Abstract
BACKGROUND AND PURPOSE Chemoradiotherapy is the primary treatment for localized anal cancer (AC). This treatment offers high rates of cure and organ preservation. Radiotherapy can however, result in late persisting anorectal dysfunction, with anal incontinence, urge and clustering. Correlation of radiation doses to pelvic substructures and functional outcome is not well described in AC. We correlated patient reported anorectal function to radiation doses to sphincters and pelvic floor muscles. MATERIALS AND METHODS Patients treated with (chemo)radiotherapy for AC were asked to fill out LARS (lower anterior resection syndrome) questionnaires at follow-up. We compared patients with no LARS (score 0-19) and patients with major LARS (30-42) as well as individual LARS questions to specific radiation doses to sphincters, levators and puborectal muscles. RESULTS Thirty-six patients were included, 18 with no LARS and 18 with major LARS. Gender, age, TNM stage, PTV, chemotherapy, time to LARS score (mean 660 and 749 days) were comparable between the two groups. LARS symptoms, occurring at least once per week, were reported between 25-55.7%, and poorer LARS outcome was associated to worse quality of life. Dose to sphincter complex (Dmean, V50Gy and D90%) differed significantly between patients with no and major LARS (p = 0.048, 0.035 and 0.02 respectively). Further, D90% to the sphincter complex was significantly higher in patients who had accidental leakage of stool, (p = 0.044). CONCLUSION Patients treated with (chemo)radiotherapy for AC show high frequency of patient reported anorectal dysfunction. Specific doses to the sphincters could become a useful predictor of anal incontinence and major LARS and incorporated into future radiotherapy planning studies.

Abstract
Fecal incontinence (FI) is defined as involuntary or uncontrollable loss of feces. Gas incontinence is defined as involuntary or uncontrollable loss of flatus, while anal incontinence is defined as the involuntary loss of feces or flatus. The prevalence of FI in people over 65 in Japan is 8.7% in the male population and 6.6% among females. The etiology of FI is usually not limited to one specific cause, with risk factors for FI including physiological factors, such as age and gender; comorbidities, such as diabetes and irritable bowel syndrome; and obstetric factors, such as multiple deliveries, home delivery, first vaginal delivery, and forceps delivery. In the initial clinical evaluation of FI, the factors responsible for individual symptoms are gathered from the history and examination of the anorectal region. The evaluation is the basis of all medical treatments for FI, including initial treatment, and also serves as a baseline for deciding the need for a specialized defecation function test and selecting treatment in stages. Following the general physical examination, together with history taking, inspection (including anoscope), and palpation (including digital anorectal and vaginal examination) of the anorectal area, clinicians can focus on the causes of FI. For the clinical evaluation of FI, it is useful to use Patient-Reported Outcome Measures (PROMs), such as scores and questionnaires, to evaluate the symptomatic severity of FI and its influence over quality of life (QoL).

Abstract
Background: The UICC TNM 7th edition introduced stage groups for anal cancer which in 2019 has not yet come into general use. The new TNM 8th edition from 2016 defines 7 sub-stages. Background data for these changes are lacking. We aimed to investigate whether the new classification for anal cancer reliably predict the prognosis in the different stages.Patients and methods: The Nordic Anal Cancer Group (NOAC) conducted a large retrospective study of all anal cancers in Norway, Sweden and most of Denmark in 2000-2007. From the Nordic cohort 1151 anal cancer patients with follow-up data were classified by the TNM 4th edition which has identical T, N and M definitions as the TNM 7th edition, and therefore also can be classified by the TNM 7th stage groups. We used the Nordic cohort to translate the T, N and M stages into the TNM 8th stages and sub-stages. Overall survival for each stage was assessed.Results: Although the summary stage groups for TNM 8th edition discriminates patients with different prognosis reasonably well, the analyses of the seven sub-stages show overlapping overall survival: HR for stage IIA 1.30 (95%CI 0.80-2.12) is not significantly different from stage I (p = .30) and HR for stage IIB 2.35 (95%CI 1.40-3.95) and IIIA 2.48 (95%CI 1.43-4.31) are also similar as were HRs for stage IIIB 3.41 (95%CI 1.99-5.85) and IIIC 3.22 (95%CI 1.99-5.20). Similar overlapping was shown for local recurrence and distant spread.Conclusion: The results for the sub-stages calls for a revision of the staging system. We propose a modification of the TNM 8th edition for staging of anal cancer into four stages based on the T, N and M definitions of the TNM 8th classification.

Abstract
Background Anal cancer is a rare disease, which might be the reason for the “one size fits all” approach still used for radiotherapy target contouring. To refine and individualize future guidelines, detailed and contemporary pattern of recurrence studies are needed. Methods Consecutive anal cancer patients, all treated with curative intent intensity-modulated radiotherapy (IMRT), were retrospectively studied (n = 170). Data was extracted from medical records and radiological images. Radiotherapy planning CT’s and treatment plans were reviewed, and recurrences were mapped and categorized according to radiation dose. Results The mean dose to the primary tumor was 59.0 Gy. With a median follow-up of 50 months (range 14–117 months), 5-year anal cancer specific survival was 86.1%. Only 1 of 20 local recurrences was located outside the high dose (CTVT) volume. More patients experienced a distant recurrence (n = 34; 20.0%) than a locoregional recurrence (n = 24; 14.1%). Seven patients (4.2%) had a common iliac and/or para-aortic (CI/PA) recurrence. External iliac lymph node involvement (P = 0.04), and metastases in ≥3 inguinal or pelvic lymph node regions (P = 0.02) were associated with a 15–18% risk of CI/PA recurrence. Following chemoradiotherapy, 6 patients with recurrent or primary metastatic CI/PA lymph nodes were free of recurrence at last follow-up. The overall rate of ano-inguinal lymphatic drainage (AILD) recurrence was 2 of 170 (1.2%), and among patients with inguinal metastases at initial diagnosis it was 2 of 65 (3.1%). Conclusions We conclude that other measures than increased margins around the primary tumor are needed to improve local control. Furthermore, metastatic CI/PA lymph nodes, either at initial diagnosis or in the recurrent setting, should be considered potentially curable. Patients with certain patterns of metastatic pelvic lymph nodes might be at an increased risk of harboring tumor cells also in the CI/PA lymph nodes.

Abstract
PURPOSE Anal cancer is a mainly treated with chemoradiotherapy. A small number of patients undergo salvage surgery. There are few published studies investigating quality of life and functional outcome after treatment for anal cancer. The aim of this review was to explore the literature and identify areas for further research. METHODS A search was conducted in Medline using MESH terms related to anal cancer and quality of life. Two investigators selected and reviewed articles based on titles and abstracts. Three investigators read and reviewed the included articles and collected relevant data. The included articles were evaluated using the minimum standard checklist, and key findings were summarised in a chart. RESULTS Some 15 articles, and a total of 802 patients, were deemed eligible. The results differed slightly among the studies. The incidence of symptoms such as fatigue, nausea, insomnia and appetite loss was higher than among healthy volunteers. Bowel function, urinary function and sexual function were negatively affected. Some studies found that, compared with the normal population, anal cancer survivors scored clinically significant worse in the functional scales in QLQ-C30. CONCLUSION In conclusion, it is apparent that several functional problems affect the quality of life of patients with anal cancer. There are few studies which have investigated quality of life after treatment for anal cancer. Interventions to address issues related to anal cancer treatment may improve long-term quality of life in this patient group. TRIAL REGISTRATION CRD42017059787.

Abstract
Our aim is to discuss the current established management of care and associated prevention strategies of anal squamous cell carcinoma (SCCA). In general, the development of SCCA is commonly linked to a prior history of HPV. Unfortunately, HPV vaccination continues to be underutilized in the United States versus other countries. Increased acknowledgment of the importance of HPV vaccination as an anticancer vaccine should be encouraged. The present standard of care is primary chemoradiotherapy (CRT), which results in a high level of disease control for small, early-stage SCCA. More advanced cancers still fare poorly with this treatment, and the disease relapses locoregionally in the majority of cases (30%-50% of patients), resulting in an abdominoperineal resection. Current treatment recommendations are associated with substantial morbidity; alternative radiation doses and/or novel combinations of agents with CRT are needed to improve quality of life and oncologic outcomes. Cytotoxic chemotherapy remains the standard of care for treatment-naïve patients with metastatic disease, with a possible new treatment paradigm of carboplatin/weekly paclitaxel. In addition, immune checkpoint inhibition appears to have a promising role in the setting of patients with refractory disease. Several clinical trials with immunotherapeutic and vaccine approaches for locally advanced and metastatic anal cancer are ongoing, as are HPV-agnostic umbrella trials. Whenever possible, clinical trial enrollment is always encouraged for further therapeutic development in the setting of a rare cancer, given the potentially substantial global impact for other HPV-associated malignancies.

Abstract
INTRODUCTION We evaluated acute and chronic side effects of 3D conformal radiotherapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) in female patients with anal carcinoma and accessed correlations between dosimetric parameters and the considered toxicities. METHODS For 70 women with anal cancer treated at our department, acute and chronic side effects and quality of life (QoL) were evaluated with questionnaires using the Common Terminology Criteria for Adverse Events (CTCAE v. 4.0.) and Late Effects in Normal Tissue, Subjective, Objective Management and Analytic Scales (LentSoma) before, during, and after the treatment. RESULTS Forty-seven out of 70 (67%) patients completed the questionnaire and were enrolled in the study. Only poor urinary stream, loss of pubic hair during chemoradiation, and chronic vaginal dryness were observed more frequently in the 3D-CRT group compared to the IMRT group (univariable logistic regression p = .032, p = .04, p = .049, respectively). After the treatment, 43% in the 3D-CRT group and 29% in the IMRT group reported a severe loss of QoL. A higher proportion among the patients receiving a genital V20 ⩾35% showed grade 1-3 side effects such as chronic dyspareunia ( p = .035; Fisher exact test). CONCLUSION Our results suggest that the use of IMRT decreases acute and chronic adverse effects although reduced QoL also occurred in the IMRT group. These effects are likely to be underreported in retrospective studies using physician-reported outcome measures.

Abstract
INTRODUCTION There is a paucity of data on incidence and mechanisms of long-term gastrointestinal consequences after chemoradiotherapy for anal cancer. Most of the adverse effects reported were based on traditional external beam radiotherapy whilst only short-term follow-ups have been available for intensity-modulated radiotherapy, and there is lack of knowledge about consequences of dose-escalation radiotherapy. METHOD A systematic literature review. RESULTS Two thousand nine hundred and eighty-five titles (excluding duplicates) were identified through the search; 130 articles were included in this review. The overall incidence of late gastrointestinal toxicity was reported to be 7-64.5%, with Grade 3 and above (classified as severe) up to 33.3%. The most commonly reported late toxicities were fecal incontinence (up to 44%), diarrhea (up to 26.7%), and ulceration (up to 22.6%). Diarrhea, fecal incontinence and buttock pain were associated with lower scores in radiotherapy specific quality of life scales (QLQ-CR29, QLQ-C30, and QLQ-CR38) compared to healthy controls. Intensity-modulated radiation therapy appears to reduce late toxicity. CONCLUSION Late gastrointestinal toxicities are common with severe toxicity seen in one-third of the patients. These symptoms significantly impact on patients' quality of life. Prospective studies with control groups are needed to elucidate long-term toxicity.

Abstract
BACKGROUND Standard treatment of localized squamous cell carcinoma of the anus (SCCA) is radiotherapy (RT) combined with chemotherapy, that is, chemoradiation (CRT). Primary surgery has a limited role, but is a recommended treatment for small well differentiated SCCA localized in the anal margin, with re-excision or postoperative RT/CRT in case of involved surgical margins. The evidence supporting these strategies is limited. AIM To study the recurrence patterns and survival outcomes in patients treated with surgery alone compared with surgery followed by postoperative RT/CRT. MATERIAL AND METHODS From a large Nordic database we identified 93 patients with stage TxT1-2N0M0 SCCA treated with surgery alone (n = 59) or surgery followed by RT/CRT (n = 34). Surgery consisted of local excision in 86 patients and abdominoperineal resection in seven patients, all of them in the surgery alone group. In 38 (41%) of the patients, the tumor was localized merely in the anal margin and in all remaining cases the anal canal was involved. Median RT dose to the tumor bed was 54 (range 46-66) Gy. Adjuvant RT to lymph nodes was given in 75% of the patients. Half of the patients received concomitant chemotherapy, usually 5-fluorouracil and mitomycin C. RESULTS The locoregional recurrence (LRR) rate was significantly higher after surgery alone compared to surgery followed by adjuvant RT/CRT (36% vs. 9%, p = .006). The 3-year recurrence free survival (RFS) and overall survival (OS) were significantly better in patients who received postoperative RT/CRT than in patients who did not (3-year RFS 84.2% vs. 52.7%, p < .001 and 3-year OS 87.2% vs. 70%, p = .026). CONCLUSIONS Surgery alone of SCCA was associated with a high LRR rate and poor survival. The addition of postoperative RT/CRT lead to significantly improved locoregional control and survival.

Abstract
The best curative option for locally advanced (stages II-III) squamous-cell carcinomas of the anal canal (SCCAC) is concurrent chemo-radiotherapy delivering 36-45 Gy to the prophylactic planning target volume with an additional boost of 14-20 Gy to the gross tumor volume with or without a gap-period between these two sequences. Although 3-dimensional conformal radiotherapy led to suboptimal tumor coverage because of field junctions, this modality remains a standard of care. Recently, intensity-modulated radiotherapy (IMRT) techniques improved tumor coverage while decreasing doses delivered to organs at risk. Sparing healthy tissues results in fewer severe acute toxicities. Consequently, IMRT could potentially avoid a gap-period that may increase the risk of local failure. Furthermore, these modalities reduce severe late toxicities of the gastrointestinal tract as well as better functional conservation of anorectal sphincter. This report aims to critically review contemporary trends in the management of locally advanced SCCAC using IMRT and concurrent chemotherapy.

Abstract
BACKGROUND While intensity modulated radiotherapy (IMRT) has been widely adopted for the treatment of anal cancer (AC), the added contour complexity poses potential risks. This study investigates the impact of contour variation on tumour control probability (TCP) when using IMRT for AC. METHODS Nine Australian centres contoured a single computed tomography dataset of a patient with AC. The same optimised template-based IMRT planning protocol was applied to each contour set to generate nine representative treatment plans and their corresponding dose volume histograms. A geometric analysis was performed on all contours. The TCP was calculated for each plan using the linear quadratic and logitEUD model. RESULTS The median concordance index (CI) for the bladder, head and neck of femur, bone marrow, small bowel and external genitalia was 0.94, 0.88, 0.84, 0.65 and 0.65, respectively. The median CI for the involved nodal, primary tumour and elective clinical target volumes were 0.85, 0.77 and 0.71, respectively. Across the nine plans, the TCP was not significantly different. Variation in TCP between plans increased as tumour cell load increased or radiation dose decreased. CONCLUSIONS When using IMRT for AC, contour variations generated from a common protocol within the limits of minor deviations do not appear to have a significant impact on TCP. Contouring variations may be more critical with increasing tumour cell load or reducing radiotherapy dose.

Abstract
BACKGROUND Sphincter-sparing radiotherapy or chemoradiation are standard treatments for patients with anal cancer. The ultimate treatment goal is full recovery from anal cancer with preserved anorectal function. Unfortunately, long-term survivors often suffer from severe anorectal symptoms. The aim of the present study was to characterize changes in anorectal physiology after radiotherapy for anal cancer. METHOD We included 13 patients (10 women, age 63.4 ± 1.9) treated with radiotherapy or chemoradiation for anal cancer and 14 healthy volunteers (9 women, age 61.4 ± 1.5). Symptoms were assessed with scores for fecal incontinence and low anterior resection syndrome. Anorectal physiology was examined with anorectal manometry and the Functional Lumen Imaging Probe. RESULTS Patients had a median Wexner fecal incontinence score of 5 (0-13) and a median LARS score of 29 (0-39). Compared to healthy volunteers, patients had lower mean (±SE) anal -resting (38 ± 5 vs. 71 ± 6, p < .001) and -squeeze pressures (76 ± 11 vs. 165 ± 15, p < .001). Patients also had lower anal yield pressure (15.5 ± 1.3 mmHg vs. 28.0 ± 2.0 mmHg, p < .001), higher distensibility, and lower resistance to flow (reduced resistance ratio of the anal canal during distension, q = 5.09, p < .001). No differences were found in median (range) rectal volumes at first sensation (70.5 (15-131) vs. 57 (18-132) ml, p > .4), urge (103 (54-176) vs. 90 (32-212), p > .6) or maximum tolerable volume (173 (86-413) vs. 119.5 (54-269) ml, p > .10). CONCLUSION Patients treated with radiotherapy or chemoradiation for anal cancer have low anal resting and squeeze pressures as well as reduced resistance to distension and flow.

Abstract
BACKGROUND Anal squamous cell carcinoma accounts for about 2-4% of all lower gastrointestinal malignancies, with a distant disease reported in less than 5%. Although surgical treatment is rarely necessary, this often involve large dissections and difficult reconstructive procedures. CASE REPORT We present a complex but successful case of double-flap reconstruction after abdominoperineal resection and groin dissection for anal squamous cell carcinoma (cT3N3M0) with metastatic right inguinal lymph nodes and ipsilateral threatening of femoral vessels. A multi-specialty team was involved in the operation. A vascular and plastic surgeon performed the inguinal dissection with en bloc excision of the saphenous magna and a cuff of the femoral vein, while colorectal surgeons carried out the abdominoperineal excision. The 2 large tissue gaps at the groin and perineum were covered with an oblique rectus abdominis myocutaneous flap and a gluteal lotus flap, respectively. A partially absorbable mesh was placed at the level of the anterior sheath in order to reinforce the abdominal wall, whereas an absorbable mesh was used as a bridge for the dissected pelvic floor muscles. The post-operative period was uneventful and the follow-up at 5 months showed good results. CONCLUSIONS An early diagnosis along with new techniques of radiochemotherapy allow patients to preserve their sphincter function. However, a persistent or recurrent disease needs major operations, which often involve a complex reconstruction. Good team-work and experience in specialized fields give the opportunity to make the best choices to perform critical steps during the management of complex cases.

Abstract
PURPOSE The optimal management of early squamous cell carcinoma of the anal canal (AC) is yet to be determined. This study investigated current practice in the management of early AC. METHODS A patterns of care survey was completed by Australian surgeons and radiation oncologists. Specific topics addressed were as follows: geographical location of practice, staging of disease, treatment approaches to T1N0 tumours and grade 3 anal intra-epithelial neoplasia (AIN3) lesions, radiotherapy planning, toxicities, follow-up and clinical trial involvement. RESULTS Sixty-four responses were obtained. For the management of T1N0 disease, half the respondents recommended standard dose chemo-radiotherapy (CRT) and one third recommended wide local excision (WLE). For the management of AIN3, half recommended WLE while a quarter advocated observation. CONCLUSIONS This study reveals a significant variation in the management of early AC. The development of guidelines specific to the treatment of early AC could standardise treatment while further research is required to define the optimal management of T1N0 AC and AIN.

Abstract
In this review, a summary of our current understanding of squamous cell carcinoma of the anus (SCCA) and the advances in our knowledge of SCCA regarding screening, prevention, the role of the immune system, current treatment and the potential for novel targets are discussed. The present standard of care in terms of treatment is 5-fluorouracil (5-FU) and mitomycin C (MMC) concurrently with radiation, which results in a high level of disease control for small early cancers. Preservation of the anal sphincter is achieved in the majority, although anorectal function is often impaired. Although evidence from prospective studies to support a change in the treatment strategy is lacking, patients with HPV-negative SCCA appear to be less responsive to chemoradiation (CRT) and relapse more frequently. In contrast, HPV-positive tumours usually fare better, but oncological outcomes are modified by smoking and immune incompetence. There is current interest in escalating the radiotherapy dose for larger, more advanced tumours, and de-escalating treatment for HPV-positive tumours. The use of novel immunological treatments to target the underlying different molecular pathways of HPV-positive cancers is exciting.

Abstract
Radical concurrent chemoradiotherapy with 5FU and Mitomycin C is the standard-of-care for squamous-cell carcinoma of the anus (SCCA). Phase III trials combined radiation doses of 50-60 Gy with concurrent Fluoropyrimidines, Mitomycin C and Cisplatin in various doses and schedules. CRT is highly successful for early T1/T2 cancers, but results in appreciable late morbidities and still fails to control larger and node-positive tumours. Compliance to chemotherapy is important for local control. Modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT), rotational IMRT, image-guided radiotherapy (IGRT) have enabled smaller margins and highly conformal plans, resulting in decreased radiation doses to the organs at risk and ensuring a shorter overall treatment time. These advances offer the potential for integrating higher doses of radiation, escalation of the currently used drugs and the safe use of other more novel agents with acceptable toxicity. In this chapter potential novel approaches are discussed in the context of SCCA.

Abstract
BACKGROUND Treatment for anal canal cancer has evolved from radical operations to definitive chemoradiotherapy (CRT), which allows for sphincter preservation in most patients. OBJECTIVE The aim of this study was to examine the use of CRT for patients with stage II and III anal cancer, among different patient demographics, geographic regions, and facility types. METHODS Utilizing the National Cancer Data Base, we examined patients with stage II and III anal canal squamous cell carcinoma from 2003 to 2010. Via univariate analysis, we examined patterns of treatment by patient demographics, tumor characteristics, geographic region, and facility type (academic vs. community). A multivariable logistic regression model was built to evaluate differences in treatment patterns when adjusting by age, sex, race, comorbidities, and stage. RESULTS A total of 12,801 patients were analyzed, of which 11,312 (88 %) received CRT. After adjusting for confounders, CRT was less likely to be administered to males [odds ratio (OR) 0.61, 95 % confidence interval (CI) 0.54-0.69], Black patients (OR 0.70, 95 % CI 0.59-0.83), and those with multiple comorbidities (OR 0.60, 95 % CI 0.51-0.72). CRT was not as widely utilized in the West (OR 0.74, 95 % CI 0.59-0.93), and patients treated in academic-based centers were less likely to receive CRT (OR 0.81, 95 % CI 0.72-0.92). Improved median overall survival was observed when CRT was utilized (p = 0.008). CONCLUSION When controlling for age, sex, race, comorbidities, and stage, discrepancies in the use of CRT for anal cancer treatment exist between demographic subtypes, geographical regions, and facility types.

Abstract
Chemoradiotherapy is the standard-of-care treatment of squamous-cell carcinoma of the anus (SCCA), and this has not changed in decades. Radiation doses of 50-60 Gy, as used in many phase III trials, result in substantial late morbidities and fail to control larger and node-positive tumours. Technological advances in radiation therapy are improving patient outcomes and quality of life, and should be applied to patients with SCCA. Modern techniques such as intensity-modulated radiotherapy (IMRT), rotational IMRT, image-guided radiotherapy using cone-beam CT, and stereotactic techniques have enabled smaller margins and highly conformal plans, resulting in decreased radiation doses to the organs at risk and ensuring a shorter overall treatment time. In this Perspectives article, the use of novel approaches to target delineation, optimized radiotherapy techniques, adaptive radiotherapy, dose-escalation with external-beam radiotherapy (EBRT) or brachytherapy, and the potential for modified fractionation are discussed in the context of SCCA.

Abstract
AIM The objective of primary radiotherapy for anal cancer is to remove cancer while maintaining anorectal function. However, little is known about anorectal function among long-term survivors without colostomy. Using a cross-sectional questionnaire study, we examined symptoms and distress related to the dysfunction of pelvic organs after radiotherapy for anal cancer. METHOD A questionnaire regarding anorectal, urinary and sexual symptoms was sent to anal cancer patients without recurrence or colostomy, diagnosed during 1996-2003, and treated with curative intent (chemo)radiotherapy at three Danish centres. For each symptom we assessed frequency and severity and the level of symptom-induced distress (no, little, moderate or great distress). RESULTS Of 94 eligible patients, 84 (89%) returned the completed questionnaire at a median of 33 months after radiotherapy. Incontinence for solid stools, liquid stools and gas occurred at least monthly in 31%, 54% and 79% of patients, respectively. Overall 40% of patients reported great distress from incontinence for solid or liquid stools at least monthly. Faecal urgency occurring at least monthly was experienced by 87% of patients and caused great distress in 43%. Stress, urge or another type of urinary incontinence occurred at least monthly in 45% and caused great distress in 21%. Urinary urgency occurred at least monthly in 48% but only caused great distress in 14%. Sexual desire was severely decreased in 58% and only 24% were satisfied with their sexual function. CONCLUSION Distressing long-term anorectal and sexual dysfunction was common after radiotherapy for anal cancer, and morbidity due to urinary dysfunction was moderate.

Abstract
AIM: To investigate the toxicity and response of intensity-modulated radiotherapy schedule intensified with a simultaneous integrated boost in anal canal cancer.
METHODS: From March 2009 to March 2014, we retrospectively analyzed 41 consecutive patients treated with intensity-modulated radiotherapy (IMRT) and concurrent chemotherapy for anal canal squamous cell carcinoma at our center. Radiotherapy was delivered via simultaneous integrated boost (SIB) technique by helical tomotherapy, and doses were adapted to two clinical target volumes according to the tumor-node-metastasis (TNM) stage: 50.6 Gy and 41.4 Gy in 23 fractions in T1N0, 52.8 Gy and 43.2 Gy in 24 fractions in T2N0, and 55 Gy and 45 Gy in 25 fractions in all patients with N positive and/or ≥ T3, respectively, to planning target volumes 1 and 2. The most common chemotherapy regimen was 5-fluorouracil and mitomycin-based. Human papilloma virus (HPV) p16 expression was performed by immunohistochemistry and evaluated in the majority of patients. Acute and late toxicity was scored according to CTCAe v 3.0 and RTOG scales.
RESULTS: The median follow-up was 30 mo (range: 12-71). Median age was 63 years (range 32-84). The stage of disease was: stage I in 2 patients, stage II in 13 patients, stage IIIA in 12 patients, and stage IIIB in 14 patients, respectively. Two patients were known to be HIV positive (4.9%). HPV p16 expression status was positive in 29/34 (85.3%) patients. The 4-year progression-free survival and overall survival in HPV-positive patients were 78% and 92%, respectively. Acute grade 3 skin and gastrointestinal toxicities were reported in 5% and 7.3% of patients, respectively; patients’ compliance to the treatment was good due to a low occurrence of severe acute toxicity, although treatment interruptions due to toxicity were required in 7.3% of patients. At 6 mo from end of treatment, 36/40 (90%) patients obtained complete response; during follow-up, 5 (13.8%) patients presented with disease progression (local or systemic).
CONCLUSION: In our experience, intensified SIB-IMRT with chemotherapy is very feasible in clinical practice, with excellent results in terms of overall survival and local control.

Abstract
Anal canal carcinomas remain rare, but their management has improved recently. The PET-CT is now used as a standard at the first diagnosis and after relapses. The introduction of intensity-modulated irradiation techniques makes it possible to better conform the pelviperineal and inguinal volumes, improving the homogeneity of the irradiation while sparing some pelvic structures, thus reducing acute and late effects. Nevertheless, the conversion from 3D to intensity-modulated radiotherapy needs a specific and careful approach, mainly for the management of the perineal region, where relapses and complications occur. Last but not least, new chemotherapy associations are studied for metastatic disease.

Abstract
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.

Abstract
Squamous cell carcinoma of the anus (SCCA) is a rare cancer but its incidence is increasing throughout the world, and is particularly high in the human immunodeficiency virus positive (HIV+) population. A multidisciplinary approach is mandatory (involving radiation therapists, medical oncologists, surgeons, radiologists and pathologists). SCCA usually spreads in a loco-regional manner within and outside the anal canal. Lymph node involvement at diagnosis is observed in 30%-40% of cases while systemic spread is uncommon with distant extrapelvic metastases recorded in 5%-8% at onset, and rates of metastatic progression after primary treatment between 10 and 20%. SCCA is strongly associated with human papilloma virus (HPV, types 16-18) infection. The primary aim of treatment is to achieve cure with loco-regional control and preservation of anal function, with the best possible quality of life. Treatment dramatically differs from adenocarcinomas of the lower rectum. Combinations of 5FU-based chemoradiation and other cytotoxic agents (mitomycin C) have been established as the standard of care, leading to complete tumour regression in 80%-90% of patients with locoregional failures in the region of 15%. There is an accepted role for surgical salvage. Assessment and treatment should be carried out in specialised centres treating a high number of patients as early as possible in the clinical diagnosis. To date, the limited evidence from only 6 randomised trials [1,2,3,4,5,6,7], the rarity of the cancer, and the different behaviour/natural history depending on the predominant site of origin, (the anal margin, anal canal or above the dentate line) provide scanty direction for any individual oncologist. Here we aim to provide guidelines which can assist medical, radiation and surgical oncologists in the practical management of this unusual cancer.

Abstract
PURPOSE The aim of this systematic review and meta-analysis was to compare the role of FDG-positron emission tomography (PET) or PET/computed tomography (CT) with conventional imaging in the detection of primary and nodal disease in anal cancer, and to assess the impact of PET or PET/CT on the management of anal cancer. METHODS A systematic review of the literature was performed. Eligible studies included those comparing PET or PET/CT with conventional imaging in the staging of histologically confirmed anal squamous cell carcinoma (SCC), or studies that performed PET or PET/CT imaging to assess response following treatment. RESULTS Twelve studies met the inclusion criteria. For the detection of primary disease, CT and PET had a sensitivity of 60 % (95 % confidence interval [CI] 45.5-75.2) and 99 % (95 % CI 96-100), respectively. Compared with conventional imaging, PET upstaged 15 % (95 % CI 10-21) and downstaged 15 % (95 % CI 10-20) of nodal disease. This led to a change in nodal staging in 28 % of patients (95 % CI 18-38). When only studies performing contemporary PET/CT were considered, the rate of nodal upstaging was 21 % (95 % CI 13-30) and the TNM stage was altered in 41 % of patients. Following chemoradiotherapy, 78 % (95 % CI 65-88) of patients had a complete response on PET. CONCLUSION Compared with conventional imaging, PET or PET/CT alters the nodal status in a sufficient number of cases to justify its routine use in the staging of patients with anal SCC.

Abstract
Squamous cell carcinoma of the anus (SCCA) is a rare cancer but its incidence is increasing throughout the world, and is particularly high in the human immunodeficiency virus positive (HIV+) population. A multidisciplinary approach is mandatory (involving radiation therapists, medical oncologists, surgeons, radiologists and pathologists). SCCA usually spreads in a loco-regional manner within and outside the anal canal. Lymph node involvement at diagnosis is observed in 30-40% of cases while systemic spread is uncommon with distant extrapelvic metastases recorded in 5-8% at onset, and rates of metastatic progression after primary treatment between 10% and 20%. SCCA is strongly associated with human papilloma virus (HPV, types 16-18) infection. The primary aim of treatment is to achieve cure with loco-regional control and preservation of anal function, with the best possible quality of life. Treatment dramatically differs from adenocarcinomas of the lower rectum. Combinations of 5FU-based chemoradiation and other cytotoxic agents (mitomycin C) have been established as the standard of care, leading to complete tumour regression in 80-90% of patients with locoregional failures in the region of 15%. There is an accepted role for surgical salvage. Assessment and treatment should be carried out in specialised centres treating a high number of patients as early as possible in the clinical diagnosis. To date, the limited evidence from only 6 randomised trials [1,2,3,4,5,6,7], the rarity of the cancer, and the different behaviour/natural history depending on the predominant site of origin, (the anal margin, anal canal or above the dentate line) provide scanty direction for any individual oncologist. Here we aim to provide guidelines which can assist medical, radiation and surgical oncologists in the practical management of this unusual cancer.
