Oncologic Outcomes of Salvage Abdominoperineal Resection for Anal Squamous Cell Carcinoma Initially Managed with Chemoradiation. J Clin Med 2024; 13:2156. [PMID: 38673429 PMCID: PMC11050212 DOI: 10.3390/jcm13082156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 04/01/2024] [Accepted: 04/03/2024] [Indexed: 04/28/2024] Open
Abstract
Background: Abdominoperineal resection (APR) has been advocated for persistent or recurrent disease after failure of chemoradiation (CRT) for anal squamous cell cancer (SCC). Treatment with salvage APR can potentially achieve a cure. This study aimed to analyze oncological outcomes for salvage APR in a recent time period at a comprehensive cancer center. Methods: A retrospective review of all patients who underwent APR for biopsy-proven persistent or recurrent anal SCC between 1 January 2007 and 31 December 2020 was performed. Patients with stage IV disease at the time of initial diagnosis and patients with missing data were excluded. Univariate analysis was used with a chi-square test for categorical variables, and non-parametric tests were used for continuous variables. Kaplan-Meier survival analysis was performed to evaluate disease-specific (DSS), post-APR local recurrence-free (RFS), and disease-free survival (DFS). Results: A total of 96 patients were included in the analysis: 39 (41%) with persistent disease and 57 (59%) with recurrent SCC after chemoradiation had been completed. The median follow-up was 22 months (IQR 11-47). Forty-nine patients (51%) underwent extended APR and/or pelvic exenteration. Eight (8%) patients developed local recurrence, 30 (31%) developed local and distant recurrences, and 16 (17%) developed distant recurrences alone. The 3-year DSS, post-APR local recurrence-free survival, and disease-free survival were 53.8% (95% CI 43.5-66.5%), 54.5% (95% CI 44.4-66.8%), and 26.8% (95% CI 18.6-38.7%), respectively. In multivariate logistic regression analysis, positive microscopic margin (OR 10.0, 95% CI 2.16-46.12, p = 0.003), positive nodes in the surgical specimen (OR 9.19, 95% CI 1.99-42.52, p = 0.005), and lymphovascular invasion (OR 2.61 95% CI 1.05-6.51, p = 0.04) were associated with recurrence of disease. Gender, indication for APR (recurrent vs. persistent disease), HIV status, extent of surgery, or type of reconstruction did not influence survival outcomes. Twenty patients had targeted tumor-sequencing data available. Nine patients had PIK3CA mutations, seven of whom experienced a recurrence. Conclusions: Salvage APR for anal SCC after failed CRT was associated with poor disease-specific survival and low recurrence-free survival. Anal SCC patients undergoing salvage APR should be counseled that microscopic positive margins, positive lymph nodes, or the presence of lymphovascular invasion in the APR specimen are prognosticators for disease relapse. Our results accentuate the necessity for additional treatment strategies for the ongoing treatment challenge of persistent or recurrent anal SCC after failed CRT.

Salvage Treatment of Recurrent or Persistent Anal Squamous Cell Carcinoma: The Role of Multi-modality Therapy. Clin Colorectal Cancer 2024; 23:85-94. [PMID: 38216367 DOI: 10.1016/j.clcc.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 12/07/2023] [Accepted: 12/10/2023] [Indexed: 01/14/2024]
Abstract
BACKGROUND The standard treatment for recurrent or persistent anal squamous cell carcinoma is surgical salvage, but disease control and survival are suboptimal. PATIENTS/METHODS Patients treated for recurrent or persistent anal squamous cell carcinoma at our institution from 2002 to 2022 were included. Patients were classified by type of salvage treatment received: surgery alone vs. reirradiation followed by surgery and by whether they received intraoperative radiation at the time of surgery. Clinical and pathologic variables were collected and assessed for association with risk of second local recurrence and death from any cause. RESULTS Sixty four patients were included; 55(85.9%) were treated with surgery alone and 9 (14.1%) were treated with reirradiation followed by surgery. Median (IQR) follow up from the time of salvage treatment was 40.0 (20.3-68.0) months. The 3-year cumulative incidence of second local recurrence (95% CI) after salvage surgery was 36% (24%-48%); 39% (26%-52%) for patients treated with surgery alone and 15% (0.46%-51%) for patients treated with reirradiation followed by surgery. Factors associated with increased second local recurrence after salvage surgery included a locoregional recurrence, lymphovascular space invasion and positive surgical margins. The 3-year overall survival (95% CI) after salvage surgery was 70% (59%-83%); 68% (7%-56%) after surgery alone and 89% (10.5%-70.6%) after reirradiation followed by surgery. Factors associated with worse overall survival included male sex, a larger recurrent tumor and positive surgical margins. CONCLUSIONS Approximately 60% of patients achieved pelvic control after salvage therapy for recurrent or persistent anal squamous cell carcinoma. Although receipt of reirradiation and intraoperative radiation were not associated with improved second local recurrence or overall survival in our cohort, patients with positive surgical margins and lymphovascular space invasion on surgical pathology had higher rates of pelvic recurrence after salvage surgery and may benefit from escalated salvage therapy.

Abstract
AIM Anal cancer incidence and mortality rates are rising in the United Kingdom (UK). Surgery is an important treatment modality for persistent or recurrent disease. There is a paucity of data on outcomes for patients undergoing pelvic exenteration for anal squamous cell carcinoma (SCC) for persistent or recurrent disease. The aim of this study was to investigate the outcomes for patients who were treated with pelvic exenteration for anal SCC from two high-volume, high-complexity pelvic exenteration units in the UK. METHOD A retrospective review of prospectively maintained databases from 2011 to 2020 was undertaken. Primary endpoints included R0 resection rates, overall and disease-free survival at 2 and 5 years. RESULTS From 2011 to 2020, 35 patients with anal SCC were selected for exenteration. An R0 resection was achieved in 26 patients (77%). Of the remaining patients, seven patients had an R1 resection and one had a R2 resection. One further patient was excluded from additional analysis as the disease was inoperable at the time of laparotomy. With a median follow-up of 19.5 months (interquartile range 7.9-53.5 months), overall survival was 50% (17/34). Patients with an R1/2 resection had a significantly poorer overall survival [0.27 (0.09-0.76), p = 0.021] than those patients in whom R0 resection was achieved. Disease-free survival was 38.2% (13/34) and an R1/R2 resection was associated with a significantly reduced disease-free survival [0.12 (0.04-0.36), p < 0.001]. CONCLUSION Complete R0 resection for recurrent or persistent anal SCC is possible in the majority of patients and improves overall and disease-free survival compared with R1/R2 resection.

Abstract
BACKGROUND Chemoradiotherapy is the primary treatment for anal cancer. 15-33% of patients will have persistent or recurrent disease after treatment requiring salvage surgery. Relapse after surgery, postoperative complications, and mortality as well as possible risk factors are not fully understood due to the rareness of the disease. The aim of the study was to report outcomes after salvage surgery as well as evaluate risk factors for postoperative complications, cancer relapse and survival. METHODS Data were retrospectively collected from electronical patients charts and pathology reports from all patients undergoing salvage surgery from July 1st, 2011 to July 1st, 2021 at the Department of Surgery, Aarhus University Hospital, Denmark. RESULTS A total of 98 patients were included in the study. The 5-year overall survival was 61.8%. Relapse after surgery occurred in 36.7% of patients and was significantly associated with R1-resection (HR = 4.4) and preoperative nodal metastases (HR = 4.5). Negative prognostic factors for survival were found to be R1-resection (HR = 3.2), preoperative nodal metastases (HR = 2.9), and male gender (HR = 0.5). There was no association found between complications and survival (HR 1.2). None of the possible risk factors were associated with major postoperative complications. CONCLUSIONS An acceptable overall survival after surgery was found. Survival and relapse-free survival was negatively associated with R1 resections and positive preoperative lymph nodes. Complications did not influence long-term survival.

Abstract
Introduction The incidence of metastatic squamous cell carcinoma of the anus (SCCA) is increasing. Even if systemic docetaxel, cisplatin, and 5-Fluorouracil (DCF) provide a high rate of long-term remission, the role of pelvic chemoradiation (CRT) is unknown in this setting. We reported the safety and efficacy of local CRT in patients with synchronous metastatic SCCA who achieved objective response after upfront DCF. Methods Patients included in Epitopes HPV01 or Epitopes HPV02 or SCARCE trials and treated with DCF followed by pelvic CRT were included. Concurrent chemotherapy was based on mitomycin (MMC) (10 mg/m² for two cycles) and fluoropyrimidine (capecitabine 825 mg/m² twice a day at each RT treatment day or two cycles of intra-venous 5FU 1000 mg/m² from day 1 to day 4). Primary endpoints were safety, local complete response rate, and local progression-free survival (PFS). Secondary endpoints were PFS, overall survival (OS), and metastasis-free survival (MFS). Results From 2013 to 2018, 16 patients received DCF followed by a complementary pelvic CRT for advanced SCCA. Median follow-up was 42 months [range, 11-71]. All patients received the complete radiation dose. Compliance to concurrent CT was poor. Overall, 13/15 of the patients (87%) had at least one grade 1-2 acute toxicity and 11/15 of the patients (73%) had at least one grade 3-4 toxicity. There was no treatment-related death. The most frequent grade 3-4 adverse effects were neutropenia (36%), dermatitis (40%), and anitis (47%). Eleven patients (73%) had at least one chronic grade 1 or 2 toxicity. One patient had a grade 4 chronic rectitis (7%). Complete local response rate was 81% at first evaluation and 62.5% at the end of the follow-up. Median local PFS was not reached and the 3-year local PFS was 77% (95%CI 76.8-77). Conclusions In patients with metastatic SCCA who had a significant objective response after upfront DCF, local CRT was feasible with high complete local response rate. The good local control rate, despite interruptions due to toxicities and low CT compliance, underline the role of pelvic RT. The high rate of toxicity prompts the need to adapt CRT regimen in the metastatic setting.

Abstract
BACKGROUND Abdominoperineal resection is the standard curative surgical technique for locally advanced adenocarcinoma of the lower rectum and squamous cell carcinoma of the anal canal after chemoradiotherapy. However, it requires a definitive abdominal colostomy that modifies the body appearance. OBJECTIVE The study aim was to evaluate the combination of abdominoperineal resection with perineal colostomy reconstruction and Malone antegrade continence enema. DESIGN This was a retrospective study. SETTINGS The study was conducted at the Toulouse Hospital Digestive Surgery Department. PATIENTS All of the patients with advanced adenocarcinoma or squamous cell carcinoma who underwent abdominoperineal resection with perineal colostomy reconstruction and Malone antegrade continence enema (n = 80) between December 1999 and December 2016 were included. MAIN OUTCOME MEASURES The main outcome was the 5-year overall survival rate. RESULTS The 5-year overall survival was 74.89% (95% CI, 62.91%-83.50%), and the median recurrence-free survival was 107.6 months (95% CI, 65.1-198.1 mo). The median follow-up was 91.0 months (95% CI, 70.4-116.6 mo). R0 resection was obtained in 64 patients (80.0%). The median Cleveland Clinic Incontinence Score (to assess the functional outcomes) was 9.0 (interquartile range, 1.0-18.0), and it was lower in patients with advanced adenocarcinoma than with squamous cell carcinoma (7.0 (interquartile range, 2.0-18.0) vs 11.0 (interquartile range, 1.0-17.0); p = 0.01). Eleven patients (13.8%) reported perineal stains during the night, and 19 patients (23.8%) needed drugs to reduce colon motility. The rate of severe complications (Clavien-Dindo >II) was 11.7% (n = 9). Definitive colostomy was performed in 15 patients (18.8%). LIMITATIONS This retrospective study included a small number of patients from a single center. Moreover, the functional outcome was tested with self-report questionnaires (risk of response bias). CONCLUSIONS This study suggests that abdominoperineal resection associated with perineal reconstruction by perineal colostomy and Malone antegrade continence enema is safe and may improve patient quality of life.

RESULTADOS ONCOLGICOS Y FUNCIONALES DE LA RECONSTRUCCIN PLVIPERINEAL MEDIANTE COLOSTOMA PERINEAL Y PROCEDIMIENTO DE MALONE DESPUS DE LA RESECCIN ABDOMINOPERINEAL ANTECEDENTES:La resección abdominoperineal es la técnica quirúrgica curativa estándar para el tratamiento del adenocarcinoma localmente avanzado del recto inferior y el carcinoma a células escamosas del canal anal, después de radio-quimioterapia. Sin embargo, requiere una colostomía abdominal definitiva que modifica la apariencia corporal.OBJETIVO:El propósito del presente estudio fue el evaluar la combinación de la resección abdominoperineal con la confección de una colostomía perineal asociada a enemas de continencia anterógrada según Malone.DISEÑO:Estudio retrospectivo.AJUSTES:Servicio de Cirugía Digestiva del Hospital de Toulouse, Francia.PACIENTES:Se incluyeron todos los pacientes con adenocarcinoma avanzado o carcinoma de células escamosas que se sometieron a resección abdominoperineal con la confección de una colostomía perineal asociada a enemas de continencia anterógrada según Malone (n = 80) entre diciembre de 1999 y diciembre de 2016.PRINCIPALES MEDIDAS DE RESULTADO:El principal resultado fue la tasa de sobrevida global a 5 años.RESULTADOS:La sobrevida global a 5 años fue de 74,89% (IC del 95%, 62,91 a 83,50) y la mediana de supervivencia libre de recurrencia fue de 107,6 meses (IC del 95%, 65,1 a 198,1). La mediana de seguimiento fue de 91,0 meses (IC del 95%, 70,4-116,6). La resección R0 se obtuvo en 64 pacientes (80,0%). La mediana de puntuación de la escala de incontinencia de la Cleveland Clinic (para evaluar los resultados funcionales) fue de 9,0 [1,0; 18,0], y fue menor en pacientes con adenocarcinoma avanzado que con carcinoma de células escamosas (7,0 [2,0; 18,0] versus 11,0 [1,0; 17,0]; p = 0,01). Once pacientes (13,8%) refirieron manchado perineal nocurno y 19 pacientes (23,8%) necesitaron fármacos para reducir la motilidad del colon. La tasa de complicaciones graves (Clavien-Dindo > II) fue del 11,7% (n = 9). Se realizó colostomía definitiva en 15 (18,8%) pacientes.LIMITACIONES:Este estudio retrospectivo incluyó un pequeño número de pacientes y de un solo centro. Además, el resultado funcional se probó con cuestionarios de autoinforme (riesgo de sesgo de respuesta).CONCLUSIONES:Este estudio sugiere que la resección abdominoperineal asociada con la confección de una colostomía perineal asociada a enemas de continencia anterógrada según Malone es segura y puede mejorar la calidad de vida de los pacientes.

Abstract
Anal cancer is a rare disease that has doubled in incidence over the last four decades. Current treatment and survival of patients with this disease has not changed substantially over this period of time, due, in part, to a paucity of preclinical models to assess new therapeutic options. To address this hiatus, we set-out to establish, validate and characterise a panel of human anal squamous cell carcinoma (ASCC) cell lines by employing an explant technique using fresh human ASCC tumour tissue. The panel of five human ASCC cell lines were validated to confirm their origin, squamous features and tumourigenicity, followed by molecular and genomic (whole-exome sequencing) characterisation. This panel recapitulates the genetic and molecular characteristics previously described in ASCC including phosphoinositide-3-kinase (PI3K) mutations in three of the human papillomavirus (HPV) positive lines and TP53 mutations in the HPV negative line. The cell lines demonstrate the ability to form tumouroids and retain their tumourigenic potential upon xenotransplantation, with varied inducible expression of major histocompatibility complex class I (MHC class I) and Programmed cell death ligand 1 (PD-L1). We observed differential responses to standard chemotherapy, radiotherapy and a PI3K specific molecular targeted agent in vitro, which correlated with the clinical response of the patient tumours from which they were derived. We anticipate this novel panel of human ASCC cell lines will form a valuable resource for future studies into the biology and therapeutics of this rare disease.

Park IJ, Chang G. Survival and Operative Outcomes After Salvage Surgery for Recurrent or Persistent Anal Cancer. Ann Coloproctol 2020; 36:361-373. [PMID: 33486907 PMCID: PMC7837391 DOI: 10.3393/ac.2020.12.29] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 12/29/2020] [Indexed: 12/24/2022] Open
Abstract
Anal squamous cell carcinoma (SCC) is a relatively rare cancer comprising less than 2.5% of all gastrointestinal malignancies. The standard treatment for anal SCC is primary chemoradiation therapy which can result in complete regression. After successful treatment, the 5-year survival is approximately 80%. However, up to 30% of patients experience recurrent persistent or recurrent disease. The role of surgery in the treatment of anal cancer, therefore, is limited to the management of recurrent or persistent disease with abdominoperineal resection and/or en bloc adjacent organ excision. Salvage surgery after irradiated anal cancer can be technically demanding in terms of acquisition of oncologically safe surgical margins and minimization of postoperative morbidity. In addition, 5-year survival outcomes after salvage resection have been reported to vary from 23% to 69%. Positive resection margins are generally regarded as the important risk factor associated with poor survival outcome. Perineal wound complications are the most common major postoperative morbidity. Because of the challenges of primary wound closure after salvage abdominoperineal resection, myocutaneous flap reconstruction has been performed to reduce the severity of perianal would complications. We, therefore, descriptively reviewed contemporary published evidence describing the treatment and outcomes after salvage surgery for persistent or recurrent anal SCC.

Abstract
There is a controversy regarding the optimal time to assess anal squamous cell carcinoma (SCC) response to chemoradiation and when salvage abdominoperineal resection (APR) should be offered. A retrospective cohort study was performed on patients with stage I-III anal SCC treated with chemoradiation in the National Cancer Database (2004-2015). The time between radiation and APR was recorded. Logistic regression and Cox proportional hazard analysis were used to determine predictors of resection margin status and overall survival. The cohort included 23 050 patients, of whom 545 (2.4%) underwent salvage APR. The median (IQR) time between radiation and resection was 3.8 (2.4-5.5) months. The rate of positive margins was 19.0%. Positive margins were more common in male, non-white patients with larger tumors, pathologic upstaging of T stage, and ≥3 months between chemoradiation and resection (all P < .05). Observing for ≥3 months between chemoradiation and APR remained associated with positive margins, even after adjusting for pretreatment tumor size (odds ratio = 2.56, 95% CI 1.46-4.47). Our data, based on the largest published cohort of anal SCC patients treated with chemoradiation and subsequent APR, suggest that patients at high risk of local treatment failure, particularly non-white men with large tumors, may benefit from early interim restaging and earlier consideration of salvage surgery.

Sarcopenia is associated with worse overall survival in patients with anal squamous cell cancer. J Surg Oncol 2020; 121:1148-1153.

Abstract
BACKGROUND AND OBJECTIVES Sarcopenia is associated with poor long-term outcomes in many gastrointestinal cancers, but its role in anal squamous cell carcinoma (ASCC) is not defined. We hypothesized that patients with sarcopenic ASCC experience worse long-term outcomes. METHODS A retrospective review of patients with ASCC treated at an academic medical center from 2006 to 2017 was performed. Of 104 patients with ASCC, 64 underwent PET/computed tomography before chemoradiation and were included in the analysis. The skeletal muscle index was calculated as total L3 skeletal muscle divided by height squared. Sarcopenia thresholds were 52.4 cm2 /m2 for men and 38.5 cm2 /m2 for women. Cox regression analysis was performed to assess overall and progression-free survival. RESULTS Twenty-five percent of the patients were sarcopenic (n = 16). Demographics were similar between groups. There was no difference in the clinical stage or comorbidities between groups. On multivariate analysis, factors associated with worse overall survival were male gender (hazard ratio [HR] 3.7, P = .022) and sarcopenia (HR 3.6, P = .019). Male gender was associated with worse progression-free survival (HR 2.6, P = .016). CONCLUSIONS Sarcopenia is associated with worse overall survival in patients with anal cancer. Further studies are indicated to determine if survival can be improved with increased attention to nutritional status in sarcopenic patients.

Abstract
PURPOSE Therapy of anal cancer follows national and international guidelines that are mainly derived from randomized trials. This study aimed to analyze long-term results of stage-dependent treatment of anal cancer in a non-selected patient cohort. PATIENTS AND METHOD All consecutive patients treated for anal cancer between 2000 and 2015 were retrieved from a prospective database. Risk-dependent screening for human immunodeficiency virus showed no infection. Main outcome measure was overall survival with respect to tumor site and treatment. Secondary endpoints were cause-specific survival, stoma free survival, and the rate of salvage operations. RESULTS In total, 106 patients were treated for anal cancer. Of those, 69 (65.1%) suffered from anal canal cancer and 37 (34.9%) from anal margin cancer. Three patients with synchronous distant metastases were excluded from analysis. The majority of patients (n = 79, 76.7%) were treated by chemoradiotherapy in curative intention. Twenty-two patients underwent local surgery. Five-year overall survival was 73.1% and cause-specific survival at 5 years was 87.4%. Overall, 14 patients (13.6%) needed salvage surgery. Their 5-year cause-specific survival was 57.7%. A permanent ostomy was avoided in 77.7%. CONCLUSIONS Treatment of anal cancer results in low rates of salvage surgery and permanent ostomies, when therapy was determined by a multidisciplinary team following national and international guidelines.

Abstract
BACKGROUND Anal squamous cell carcinoma (ASCC) is the most common histological subtype of anal cancer. Rates have been observed to increase in recent years. Combined chemoradiotherapy (CCRT) is currently the gold standard of treatment. The aim of this study is to assess ASCC prevalence, treatment trends, and overall survival (OS) in the United States. METHODS Patients diagnosed with stage I-IV ASCC were identified from the National Cancer Database from 2004 to 2015. The primary outcome was 5-year OS, which was analyzed using Kaplan-Meier survival curves, log-rank test, and Cox proportional hazards models. RESULTS 34,613 cases were included (stage I: 21.45%; II: 41.00%; III: 31.62%; IV: 5.94%), with an increasing trend in prevalence. CCRT was the most used treatment. Multimodal treatment, combining surgery with CCRT, offered the best OS rates for stage I, II, and IV cancers (I: 84.87%; II: 75.12%; IV: 33.08%), comparable with survival of stage III patients treated with CCRT (III: 61.14%). Radiation alone had the worse OS rates, and on adjusted analysis, radiation treatment alone had the greatest risk of mortality (I: hazard ratio, 2.01; 95% confidence interval, 1.14-3.54; P = 0.016; II: 2.05, 1.44-2.93, P < 0.001; IV: 1.99, 0.99-4.02, P = 0.054). CONCLUSIONS ASCC has increased in prevalence, notably in stage III and IV disease. Although CCRT is the most commonly used treatment type for all stages of ASCC, multimodal treatment offers better OS in stages I, II, and IV. Treatment with radiation alone offers the worst OS no matter the stage and should no longer be used as a solitary treatment modality.

Abstract
AIM Up to 30% of patients with squamous cell cancer of the anus (SCCA) will require a salvage abdominoperineal resection (APR) for either persistent or recurrent disease. The objective of this study was to assess cancer-related outcomes in patients with (i) persistent or (ii) recurrent SCCA. METHOD Embase and MEDLINE were searched. Publications were included if they assessed overall survival (OS), disease-free survival (DFS) and locoregional recurrence or metastatic disease after salvage APR for persistent or recurrent SCCA. RESULTS A total of 28 retrospective case series (study size ranged from nine to 111) met our inclusion criteria. The median time to salvage APR was 2.6 months [interquartile range (IQR) 2.6-5.0 months, six studies] for persistent disease and 27.6 months (IQR 15.0-32.7 months, five studies) for recurrent disease. The median 5-year OS from the time of salvage APR was 45.0% (IQR 32.0%-52.3%, 10 studies) for persistent disease and 51.0% (IQR 36.0%-60.9%, 11 studies) for recurrent disease. The median 5-year DFS following salvage APR was 44.0% (IQR 29.5%-53.0%, 10 studies) for all patients. Following salvage APR, the median locoregional recurrence rate was 23.5% (IQR 15.8%- 46.9%, 19 studies) and 9.0% (IQR 6.4%-13.3%, 16 studies) of patients developed metastatic disease after salvage APR. CONCLUSION Our review characterizes the best evidence for outcomes following salvage APR for patients with persistent or recurrent SCCA. The evidence is limited by the quality of included studies, as many were single centre case series.

Abstract
BACKGROUND/OBJECTIVES The first-line treatment for anal squamous cell carcinoma is Nigro protocol chemoradiotherapy. Some patients will fail curative intent chemoradiotherapy and have persistent disease while others may have an initial response followed by disease recurrence. The goal of this study is to investigate survival in anal squamous cell carcinoma patients who fail first-line treatment. METHODS The National Cancer Database (2004-2013) was used to identify patients with anal squamous cell carcinoma. The primary outcome was overall survival. RESULTS There were 256 patients in the early salvage group who underwent abdominoperineal resection (APR) within 6 months of completing chemoradiotherapy and 181 patients in the late salvage group who had APR 6 months or more after completion of chemoradiotherapy. Both groups of patients had similar tumor size (45 vs 50 mm; P = 0.07) and rate of positive margins (21.5% vs 15.6%;P = 0.13). There was no significant difference in overall survival between early and late salvage APR (hazard ratio [HR]: 0.81; 95% confidence interval [CI]: 0.50-1.32; P = 0.40). CONCLUSIONS The overall survival of anal squamous cell carcinoma patients undergoing early vs late salvage APR after failure of chemoradiotherapy is similar. As a result, patients with persistent disease should be offered surgery just as readily as those with recurrent disease.
