Capecitabine/Mitomycin versus 5-Fluorouracil/Mitomycin in Combination with Simultaneous Integrated Boost Intensity-Modulated Radiation Therapy for Anal Cancer. Curr Oncol 2023; 30:8563-8574. [PMID: 37754536 PMCID: PMC10528380 DOI: 10.3390/curroncol30090621] [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: 07/31/2023] [Revised: 09/15/2023] [Accepted: 09/15/2023] [Indexed: 09/28/2023] Open
Abstract
Since EXTRA, a non-randomized phase II trial with 31 patients, explored the use of capecitabine, mitomycin and radiation therapy (RT) in the treatment of localized squamous cell carcinoma of the anal canal (SCCAC), this treatment has been considered as an acceptable alternative to infusional 5-FU. However, the differences in efficacy between capecitabine and 5-FU in chemoradiation therapy (CRT) with simultaneous integrated boost (SIB) radiation therapy (SIB-IMRT) for local SCCAC are not well documented. Patients included in this prospective monocentric cohort study were treated with SIB-RapidArc (a unique RT method treatment for all patients: identical technique, volume and constraints for at-risk organs), mitomycin C and 5-FU each day of RT for 7 weeks (group 1) or capecitabine each day of RT (group 2). Patients treated between July 2009 and August 2017 (group 1) and between November 2012 and April 2018 (group 2) for local SCCAC T2-4 classified as N, M0 or T, N1-3, M0 were included. Primary endpoints were progression-free survival (PFS) and acute toxicities. Results: One hundred forty-seven patients were included, 91 in group 1 and 56 in group 2. The two groups were statistically comparable in terms of sex, Eastern Cooperative Oncology Group Performance Status (ECOG PS) and TNM. With a median duration of follow-up of 53.5 months, the PFS rate at 3 years was 80% for group 1 and 75% for group 2 (p = 0.32). The 3-year colostomy-free survival rate was 92% for group 1 and 85% for group 2 (p = 0.11). The rate of patients with at least one grade 3 or higher acute toxicity was 35.5% in group 1 and 21.4% in group 2 (p = 0.10), with a trend of fewer acute toxicities with capecitabine. Conclusion: Capecitabine/mitomycin in combination with SIB RapidArc radiation therapy for anal cancer seems as effective as 5-FU-based chemotherapy and is well tolerated with minimal toxicity.

A Prospective Study of Chemoradiotherapy as Primary Treatment in Patients With Locoregionally Advanced Penile Carcinoma. Int J Radiat Oncol Biol Phys 2023; 117:139-147. [PMID: 37030606 DOI: 10.1016/j.ijrobp.2023.03.066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/03/2023] [Accepted: 03/24/2023] [Indexed: 04/10/2023]
Abstract
PURPOSE Neoadjuvant chemotherapy followed by surgery for locoregionally advanced penile carcinoma (LAPSCC) is associated with severe toxicity and a 1-year survival probability of ∼50%. We aimed to evaluate the safety and efficacy of chemoradiotherapy (CRT) as the primary treatment for LAPSCC and the association of high-risk human papillomavirus (hrHPV) with the outcome. METHODS AND MATERIALS This was a prospective, single-center, single-arm study of CRT in LAPSCC, defined as a large/inoperable primary tumor, large palpable nodes, suspicion of extranodal extension or pelvic nodal involvement, and no distant metastases. CRT consisted of 49.5 Gy (33 × 1.5 Gy) on affected inguinal and pelvic areas combined with intravenous mitomycin C on day 1 and capecitabine on radiation days. Primary tumors and positron emission tomography/computed tomography-positive deposits received a boost of 59.4 Gy (33 × 1.8 Gy). The response was evaluated by 18F-fluorodeoxyglucose positron emission tomography/computed tomography. If feasible, patients with residual/recurrent disease underwent salvage surgery. The primary endpoint was 1-year progression-free survival (PFS), reached when 1-year PFS was ≥50%. Other endpoints were 2-year PFS, overall survival, and toxicity rates. Kaplan-Meier survival curves were compared using the log-rank test. RESULTS Thirty-three patients were included: 29 (88%) with stage IV disease (T4 any-N M0 and/or any-T N3 M0) and 8 (24%) with hrHPV-positive disease. Median follow-up was 41 months. Thirty-two completed CRT. Eleven (33%) experienced ≥1 grade 3 treatment-related adverse event. There were no grade 4 or 5 treatment-related events. Twenty-four patients (73%) responded, including 13 (39%) complete responses. Nine patients (27%) underwent salvage surgery, and an additional 8 patients underwent later surgery (together 52%). One- and 2-year PFS were 34% and 31%, respectively. One- and 2-year overall survival were 73% and 46%, respectively. No significant difference between patients with hrHPV-positive and -negative tumors was observed. CONCLUSIONS CRT is a viable treatment option for LAPSCC with acceptable toxicity. CRT can result in an enduring response. If patients have residual tumor, salvage surgery is feasible. HrHPV status was not associated with outcomes.

Abstract
Background and purpose To gain insight into the treatment outcomes for anal cancer a retrospective analysis was performed with a special emphasis on trends in outcome and toxicities over time and on treatment of elderly patients. Materials and methods Medical records of 98 consecutive patients with squamous cell carcinoma of the anus of all stages treated with curative intent between 01-01-2009 and 31-12-2018 were analyzed with follow up until 31-12-2020. Standard tumor and pathological lymph node dose were 59.4 Gy (median 59.4 Gy, range 59.4–70 Gy) or 60 Gy (no deviation from intended dose), elective nodal regions were treated with 45 Gy (no deviations). Radiotherapy techniques in this period evolved from 3D-conformal to IMRT and VMAT. In 23 patients electron beams were used. Results Median age was 63 years (range 41–88), the majority of patients were female (60%). Twenty three patients were > 75 years old. The TNM stages were I, II, IIIA, and IIIB in 18%, 40%, 15% and 27%, 58% of patients had N0 status. Concurrent mitomycin C and 5-fluoruracil-based chemotherapy was given in 63 patients (64%). Five-year overall survival (OS), disease free survival (DFS), locoregional control (LRC) and colostomy free survival (CFS) were 71%, 80%, 82%, and 82% for the whole group. Results in patients > 75 years of age were not statistically different from those in younger patients. With the introduction of more conformal techniques DFS did not change and toxicities decreased. Conclusion Real word treatment outcomes per disease stage were in line with what is reported in literature. Older patients should also be offered treatment with curative intent.

Sissung TM, Figg WD. Pharmacogenomics Testing in Phase I Oncology Clinical Trials: Constructive Criticism Is Warranted. Cancers (Basel) 2022; 14:cancers14051131. [PMID: 35267440 PMCID: PMC8909728 DOI: 10.3390/cancers14051131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 02/08/2022] [Accepted: 02/19/2022] [Indexed: 12/04/2022] Open
Abstract
Simple Summary Phase I clinical trials are a cornerstone of pharmaceutical development in oncology. Many studies have now attempted to incorporate pharmacogenomics into phase I studies; however, many of these studies have fundamental flaws that that preclude interpretation and application of their findings. Study populations are often small and heterogeneous with multiple disease states, multiple dose levels, and prior therapies. Genetic testing typically includes few variants in candidate genes that do no encapsulate the full range of phenotypic variability in protein function. Moreover, a plurality of these studies do not present scientifically robust clinical or preclinical justification for undertaking pharmacogenomics studies. A significant amount of progress in understanding pharmacogenomic variability has occurred since pharmacogenomics approaches first began appearing in the literature. This progress can be immediately leveraged for the vast majority of Phase I studies. The purpose of this review is to summarize the current literature pertaining to Phase I incorporation of pharmacogenomics studies, analyze potential flaws in study design, and suggest approaches that can improve design of future scientific efforts. Abstract While over ten-thousand phase I studies are published in oncology, fewer than 1% of these studies stratify patients based on genetic variants that influence pharmacology. Pharmacogenetics-based patient stratification can improve the success of clinical trials by identifying responsive patients who have less potential to develop toxicity; however, the scientific limits imposed by phase I study designs reduce the potential for these studies to make conclusions. We compiled all phase I studies in oncology with pharmacogenetics endpoints (n = 84), evaluating toxicity (n = 42), response or PFS (n = 32), and pharmacokinetics (n = 40). Most of these studies focus on a limited number of agent classes: Topoisomerase inhibitors, antimetabolites, and anti-angiogenesis agents. Eight genotype-directed phase I studies were identified. Phase I studies consist of homogeneous populations with a variety of comorbidities, prior therapies, racial backgrounds, and other factors that confound statistical analysis of pharmacogenetics. Taken together, phase I studies analyzed herein treated small numbers of patients (median, 95% CI = 28, 24–31), evaluated few variants that are known to change phenotype, and provided little justification of pharmacogenetics hypotheses. Future studies should account for these factors during study design to optimize the success of phase I studies and to answer important scientific questions.

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%.

Combining Adjuvant Radiotherapy With Capecitabine in Chemotherapy-resistant Breast Cancer: Feasibility, Safety, and Toxicity. Clin Breast Cancer 2020; 20:344-352.e1. [PMID: 32234364 DOI: 10.1016/j.clbc.2020.02.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 02/21/2020] [Accepted: 02/28/2020] [Indexed: 12/23/2022]
Abstract
BACKGROUND In a randomized trial (CREATE-X), patients with residual disease after standard neoadjuvant chemotherapy had improved survival with the addition of adjuvant capecitabine. For patients who required radiotherapy (RT), capecitabine was given sequentially. Concurrent capecitabine-RT might be more efficacious. We hypothesized that the safety, feasibility, and toxicity of adjuvant capecitabine-RT would not be significantly different compared with adjuvant RT alone. PATIENT AND METHODS We retrospectively studied the data from patients with stage I-III invasive mammary carcinoma. Patients who had received capecitabine-RT were matched 1:3 with control patients who had received RT alone. Logistic regression analysis was used to evaluate the predictors of radiation dermatitis. RESULTS A total of 64 patients were enrolled, including 16 who had received capecitabine-RT and 48 who had received RT alone. The cohorts were balanced regarding the clinicopathologic factors. No treatment in either cohort resulted in hospitalization, short-term disability, or fatality. Most toxicities of capecitabine-RT were related to radiation dermatitis. Radiation dermatitis was not significantly different between the capecitabine-RT and RT cohort at either grade 2 (odds ratio [OR], 1.36; 95% confidence interval [CI], 0.38-4.93; P = .63) or grade 3 (OR, 3.00; 95% CI, 0.85-10.63; P = .09) or after multivariable analysis. However, the capecitabine-RT group was more likely to require modifications in the RT schedule, including treatment breaks or cancelled fractions (44% vs. 17%; OR, 3.89; 95% CI, 1.12-13.52; P = .03). CONCLUSION Capecitabine-RT appears to be safe in the adjuvant treatment of breast cancer with comparable toxicity to RT alone. It might require more treatment adjustments. Prospective studies are needed to evaluate the safety and tolerability of this combination.

Abstract
Capecitabine is an oral prodrug of the anticancer drug 5‐fluorouracil (5‐FU). The primary aim of this study was to develop a pharmacokinetic model for capecitabine and its metabolites, 5′‐deoxy‐5‐fluorocytidine (dFCR), 5′‐deoxy‐5‐fluorouridine (dFUR), 5‐FU, and fluoro‐β‐alanine (FBAL) using data from a heterogeneous population of cancer patients (n = 237) who participated in seven clinical studies. A four‐transit model adequately described capecitabine absorption. Capecitabine, dFCR, and FBAL pharmacokinetics were well described by two‐compartment models, and dFUR and 5‐FU were subject to flip‐flop pharmacokinetics. Partial and total gastrectomy were associated with a significantly faster capecitabine absorption resulting in higher capecitabine and metabolite peak concentrations. Patients who were heterozygous polymorphic for a genetic mutation encoding dihydropyrimidine dehydrogenase, the DPYD*2A mutation, demonstrated a 21.5% (relative standard error 11.2%) reduction in 5‐FU elimination. This comprehensive population model gives an extensive overview of capecitabine and metabolite pharmacokinetics in a large and heterogeneous population of cancer patients.

Abstract
BACKGROUND/AIMS An organ preservation approach using chemoradiotherapy has been established for anal cancer. This retrospective cohort study aimed to define the clinico-demographic characteristics and outcomes of cases of human immunodeficiency virus (HIV)-negative anal carcinoma during a period of 20 years in a single comprehensive cancer institute. MATERIALS AND METHODS This was a single-center retrospective cohort study of patients who were treated between January 1995 and January 2015. The primary outcome measures that were investigated included overall survival (OS), progression-free survival (PFS), colostomy rates, and colostomy-free survival (CFS). RESULTS A total of 28 patients who were principally treated with standard 5-fluorouracil + mitomycin combination chemoradiotherapy were eligible for analysis. The 3- and 5-year PFS rates were 92.4% and 63%, respectively. The lower T stage was found to be associated with a prolonged PFS (p=0.001). The 3- and 5-year CFS rates were 84.3% and 74.9%, respectively. A longer CFS was observed with lower T stages (p=0.05). At the last follow-up, 75% of the patients with anal cancer were alive, and 71.4% of the patients were disease free. The median OS was not reached with a median follow-up of 54 months (range, 6-115 months). The 3- and 5-year OS rates were 82% and 71.1%, respectively. No late toxicity was observed during the follow-up period. DISCUSSION The short- and long-term prognoses of HIV-negative patients with anal squamous cell carcinoma were good, and low-grade toxicity was rare, thereby demonstrating that these patients can be successfully treated in a real-life setting with favorable outcomes.

Abstract
OBJECTIVES To compare maximum tumour diameter (MTD) and gross tumour volume (GTV) measurements between T2-weighted (T2-w) and diffusion-weighted (DWI) MRI in squamous cell carcinoma of the anal canal (SCCA) and assess sequence impact on tumour (T) staging. Second, to evaluate interobserver agreement and reader delineation confidence. METHODS The staging MRI scans of 45 SCCA patients (25 females) were assessed retrospectively by two independent radiologists (0 and 5 years' experience of anal cancer MRI). MTD and GTV were delineated on both T2-w and high-b-value DWI images and compared between sequences; T staging was derived from MTD. Interobserver agreement was assessed and delineation confidence scored (1 to 5) by each observer. RESULTS GTV and MTD were significantly and systematically lower on DWI versus T2-w sequences by 14.80%/9.98% (MTD) and 29.70%/12.25% (GTV) for each reader, respectively, causing T staging discordances in approximately a quarter of cases. Bland-Altman limits of agreement were narrower and intraclass correlation coefficients higher for DWI. Delineation confidence was greater on DWI: 40/42 cases were scored confidently (4 or 5) by each reader, respectively, versus 31/36 cases based on T2-w images. CONCLUSIONS Sequence selection affects SCCA measurements and T stage. DWI yields higher interobserver agreement and greater tumour delineation confidence. KEY POINTS • MTD and GTV measurements are significantly lower on DWI than on T 2 -w MRI. • Such differences cause T staging discordances in up to a quarter of cases. • DWI results in higher agreement between inexperienced and experienced observers. • DWI offers greater tumour delineation confidence to inexperienced readers.

Complex Reconstruction with Flaps After Abdominoperineal Resection and Groin Dissection for Anal Squamous Cell Carcinoma: A Difficult Case Involving Many Specialities. AMERICAN JOURNAL OF CASE REPORTS 2018; 19:61-67. [PMID: 29339717 PMCID: PMC5782837 DOI: 10.12659/ajcr.906818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2017] [Accepted: 10/16/2017] [Indexed: 11/30/2022]
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
INTRODUCTION This document is a summary of the French Intergroup guidelines regarding the management of anal carcinomas, published in November 2016. METHODS It is a collaborative work produced under the auspices of the majority of the French medical societies involved in the management of anal cancer. It is based on the previous guidelines published in 2010. Recommendations are graded in three categories, according to the amount of evidence found in the literature. RESULTS Non-metastatic anal carcinomas can be divided into two risk groups, according to magnetic resonance imaging (MRI) or endorectal-ultrasonograpy. Localized small cancers (T1N0) are mainly treated by exclusive radiation therapy in the case of cancers of the anal canal, or by surgery in the case of cancers of the anal margin. The recommended treatment of locally advanced tumours (T2-T4, N0-N2) is definitive concomitant radio-chemotherapy. Salvage surgery should be reserved for patients with poor response, tumour progression or local relapse after radio-chemotherapy, or in cases of persistent vaginal fistula or total anal incontinence after the cessation of radio-chemotherapy. In the case of metastatic tumours, current therapeutic recommendations are based on less robust evidence; with chemotherapy playing a major role. CONCLUSION These recommendations are permanently being reviewed, and each individual case must be discussed inside a multidisciplinary team.

Abstract
The treatment of anal cancer has evolved remarkably in the past 30 years. Definitive chemoradiotherapy is the standard of care, allowing organ preservation and maintenance of continence for most patients. This article reviews recent advances in radiotherapy planning and delivery that have resulted in improvements in treatment-related toxicity. Most notably, the advent and wide adoption of intensity-modulated radiotherapy provides a superior toxicity profile compared with older techniques, while maintaining similar oncologic outcomes. Current areas of active research include optimizing and individualizing treatment intensity and possible integration of biologic agents and immunotherapies in the treatment of anal cancer.

Abstract
Background Many studies have demonstrated that a higher radiotherapy dose is associated with improved outcomes in non-small-cell lung cancer (NSCLC). We performed a dosimetric planning study to assess the dosimetric feasibility of intensity-modulated radiation therapy (IMRT) with a simultaneous integrated boost (SIB) in locally advanced NSCLC. Methods We enrolled twenty patients. Five different dose plans were generated for each patient. All plans were prescribed a dose of 60 Gy to the planning tumor volume (PTV). In the three SIB groups, the prescribed dose was 69 Gy, 75 Gy, and 81 Gy in 30 fractions to the internal gross tumor volume (iGTV). Results The SIB-IMRT plans were associated with a significant increase in the iGTV dose (P < 0.05), without increased normal tissue exposure or prolonged overall treatment time. Significant differences were not observed in the dose to the normal lung in terms of the V5 and V20 among the four IMRT plans. The maximum dose (Dmax) in the esophagus moderately increased along with the prescribed dose (P < 0.05). Conclusions Our results indicated that escalating the dose by SIB-IMRT is dosimetrically feasible; however, systematic evaluations via clinical trials are still warranted. We have designed a further clinical study (which is registered with ClinicalTrials.gov, number NCT02841228).

Capecitabine With Mitomycin Reduces Acute Hematologic Toxicity and Treatment Delays in Patients Undergoing Definitive Chemoradiation Using Intensity Modulated Radiation Therapy for Anal Cancer. Int J Radiat Oncol Biol Phys 2017; 98:1087-1095. [PMID: 28721892 DOI: 10.1016/j.ijrobp.2017.03.022] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2016] [Revised: 03/11/2017] [Accepted: 03/14/2017] [Indexed: 10/19/2022]
Abstract
PURPOSE To assess the impact on acute toxicity of replacing 5-fluorouracil (5-FU) with capecitabine in definitive chemoradiation for patients with anal squamous cell carcinoma (ASCC). METHODS AND MATERIALS We retrospectively reviewed the records of 107 consecutive patients with nonmetastatic ASCC treated with definitive chemoradiation from January 2009 to May 2014. In 2011, based on the noninferiority of capecitabine versus 5-FU, our institutional practice shifted to use capecitabine instead of 5-FU for ASCC. Of 107 patients, 63 were treated with infusional 5-FU (1000 mg/m2/day for 4 days) and mitomycin C (MMC) (10 mg/m2) during weeks 1 and 5, and 44 patients were treated with capecitabine (825 mg/m2 twice daily) Monday through Friday throughout radiation therapy (RT) and MMC (10 mg/m2) during weeks 1 and 5. The incidence of grade 3 to 4 acute toxicity was compared between the 2 groups. RESULTS The median age at diagnosis was 59 years, and 78 patients (73%) were female. The patient characteristics were similar between the 2 treatment groups. All patients in both groups were treated with intensity modulated RT (median dose, 56 Gy). In the 5-FU group, 52% experienced grade 3 to 4 neutropenia compared with 20% in the capecitabine group (P=.001). Treatment breaks resulting from toxicity, primarily related to grade 3+ hematologic toxicity, were necessary for 42% of patients treated with 5-FU versus 16% of those treated with capecitabine (P=.006). CONCLUSIONS Pelvic radiation therapy with MMC plus capecitabine was well tolerated and appeared to have less grade 3+ acute hematologic toxicity and fewer treatment interruptions than in a population of ASCC patients undergoing definitive chemoradiation with MMC and 5-FU.

Abstract
INTRODUCTION Standard treatment for locally advanced anal cancer is chemoradiotherapy with mitomycin C and fluorouracil. However, infusional fluorouracil requires central venous catheter placement potentiating risk of infection and thrombosis. Capecitabine which is an oral tumor activated fluoropyrimidine carbamate is an established treatment alternative to infusional fluorouracil for patients with gastrointestinal cancers. Areas covered: This review examines and discusses the current evidence for substitution of Capecitabine for infusional fluorouracil in locally advanced anal cancer. Two phase II studies, one phase I study and three retrospective reviews were identified. The rate of complete response and locoregional control with the use of Capecitabine in all of these studies ranged from 77% to 89.1% and 79% to 94% respectively, and these results are comparable with prior pivotal studies. The main toxicity with radiation and Capecitabine is radiation dermatitis occurring in 23% to 63% of patients. Despite high rates of radiation dermatitis, treatment completion rates were high, suggesting that it is a well tolerated protocol. Expert commentary: Capecitabine has been used widely in other gastrointestinal cancers, including rectal cancer in chemo-radiotherapy protocols, with proven efficacy and safety and could be a reasonable treatment alternative to fluorouracil in locally advanced anal cancer.

Abstract
UNLABELLED This was a phase II study of capecitabine in substitution of 5-fluorouracil (5-FU) in the chemoradiotherapy regimen for patients with localized squamous cell carcinoma of the anal canal. BACKGROUND Combined chemoradiation with infusional 5-FU and mitomycin is the standard treatment for localized squamous cell carcinoma (SCC) of the anal canal. Capecitabine is an oral fluoropirimidine that has been shown to be equally effective to 5-FU in many solid tumors. However, the efficacy of the substitution of 5-FU for capecitabine in anal SCC needs confirmation. METHODS Patients with SCC of anal cancer T2-4N0M0 or T (any) N1-3M0, with good performance status and normal blood and renal function, were treated with capecitabine 825 mg/m(2) bid during radiotherapy associated with a single dose of mitomycin 15 mg/m(2) on day 1. The primary objective was local control rate at 6 months determined by clinical examination and radiological assessment. Sample size was calculated using the Fleming single-stage design. RESULTS From November 2010 to February 2014, N = 51 patients were initially included; however, 43 patients were assessed. Seventeen patients (39.5%) were stage II, 11 patients (25.6%) stage IIIA, and 15 patients (34.9%) stage IIIB. Four patients (9.3%) were HIV positive. With a median follow-up of 23.1 months (range 4 to 44.4 months), 3 patients (7%) presented partial response, 37 (86%) had complete response, and 3 patients developed progression of the disease (7%) at 6 months. The colostomy rate was 18.6%. It was observed a locoregional control of 86% in 6 months (CI 95% 0.72-0.94). The main grade 3-4 toxicities were grade 3 radiodermitis in 10 patients (23.2%), grade 3 lymphopenia in 5 patients (11.6%), and grade 3 neutropenia in 2 patients (6.9%). One HIV-positive patient had septic shock, pneumonia, herpetic encephalitis, atrial fibrillation, and macrophage activation syndrome. CONCLUSIONS Capecitabine can safely substitute infusional 5-FU in the standard chemoradiation regimen for SCC of the anal cancer, with a locoregional control of 86% in 6 months (CI 95% 0.72-0.94).

Abstract
Background The standard treatment for localised squamous cell carcinoma of the anal canal (SCCAC) is chemoradiotherapy (CRT) with infusional 5-fluorouracil (5-FU) and mitomycin. Because 5-FU and capecitabine have offered similar efficacy in many phase-III trials of solid tumours, studies have tested capecitabine in this setting of SCCAC. However, these studies are small and have reported variable results. Therefore, a systematic review and meta-analysis was performed. Methods Medline, Scopus and Embase were searched for studies that evaluated the efficacy outcomes of capecitabine used as a substitute of 5-FU in the CRT of localised SCCAC. The primary endpoint was complete response rate (CRR) at 6 months. Metaprop analysis of reported CRR-based on pooled estimates of proportions with corresponding 95% confidence intervals (95%CI) were calculated on the base of the Freeman-Tukey double arcsine transformation. Results We retrieved 300 studies, of which six met our eligibility criteria. The capecitabine dose ranged from 500 mg/m2 to 825 mg/m2 BID for 5 days per week during radiation. With a total of 218 patients, the median follow-up was 21.5 months (14–23). The pooled analysis of three trials (N = 132 patients) reported a CRR at 6 months of 88% (83%–94%), considering all clinical stages. The pooled analysis of overall CRR (N = 218 patients), evaluated at different intervals, showed an overall CRR of 91% (87%–95%). Rates of locoregional relapse varied from 3.2% to 21%. The majority of patients completed the planned radiotherapy dose (93.5%–100%) and any chemotherapy interruption was reported in up to 55.8% of patients. Conclusions Capecitabine is an acceptable and more convenient alternative to infusional 5-FU in the CRT for localised SCCAC, offering similar clinical CRR to those reported by phase-III trials.

Abstract
There are very few data on the expansion from the clinical target volume (CTV) to the planning target volume (PTV) in the anal cancer treatment. This article aims to collect the different elements needed for the construction of a PTV from scientific data based on a literature analysis. We reviewed the articles published in the medical literature from the last 20years. They concerned setup errors and internal organ mobility of the different volumes of patients treated by conformational radiotherapy and intensity-modulated radiotherapy (anal canal, meso-rectum, common, intern and extern, inguinal and pre-sacral lymph nodes). CTV to PTV margins admitted in the guidelines and atlas of consensus groups (SFRO, RTOG, AGITG) are from 0.7 to 1cm in all directions, based on expert's opinions but not on scientific data. There are no specific studies on the canal anal mobility. Most of the data are from other pelvis cancers (gynecologic, rectum and prostate). Setup errors can be reduced by daily imaging. Patient repositioning and immobilization modalities are mostly local habits rather than scientific consensus. A three-dimensional 1cm margin is generally admitted. Margins reduction must be careful and has to be assessed.

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 and purpose To retrospectively evaluate locoregional control (LRC), survival and toxicity in anal cancer patients treated with simultaneous integrated boost - intensity modulated radiation therapy (SIB-IMRT) ± concurrent chemotherapy. Methods and materials Patients with squamous cell anal carcinoma stage T1(≥1 cm)-4, N0-3, M0-1 were included. All patients were treated with SIB-IMRT to a total dose of 59.4 Gy delivered to the primary tumor and macroscopically involved lymph nodes and 49.5 Gy to elective lymph node areas. If macroscopic residual tumor was still present in the fifth week of irradiation, a sequential boost of 5.4 Gy was given. Concurrent chemotherapy was administered in locally advanced cases. Acute and late toxicity were scored. Results One hundred and six patients treated consecutively between April 2006 and December 2012 were included. Eighty-seven (82.1%) patients received concurrent chemotherapy. The median follow-up was 47 months (range 2-104 months). Ninety-eight patients reached a clinical complete response (92.5%). Four-year actuarial LRC rate, overall survival and colostomy-free survival were 79%, 77% and 77%, respectively. Acute grade ≥3 toxicity occurred in 67.9% of the patients. Late grade 3 toxicity was seen in 16 patients (15.1%). Conclusions SIB-IMRT ± concurrent chemotherapy for anal cancer was effective with acceptable toxicity.

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
INTRODUCTION Anal cancer is a relatively rare malignancy which comprises about 2.5% of all digestive system malignancies in the United States. The majority of cases are squamous cell carcinoma which is closely related to human papilloma virus (HPV) infection. Despite high cure rates with chemoradiation alone, 10 - 20% of patients do develop metastatic disease with little data to guide their treatment. AREAS COVERED In this review article, the authors describe the current standard treatment of early and advanced squamous cell carcinoma of the anal canal based on published data. The authors then describe the new approaches to the disease, focusing on new radio sensitizing agents, systemic targeted drugs and immunotherapy. EXPERT OPINION The authors believe that current standard treatment options for squamous cell carcinoma of the anal canal are well defined with acceptable results. However the major challenge in the treatment of anal cancer is the lack of randomized or even large single arm Phase II trials due to rarity of the disease, especially in the metastatic disease. But we are slowly making progress. Currently, the most promising areas of research are immunotherapy, targeted therapy and even HPV prevention. We are eagerly anticipating the results of these studies in order to expand the treatment armamentarium.

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
PURPOSE To evaluate the feasibility and efficacy of simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) in patients with limited-disease small-cell lung cancer (LD-SCLC). METHODS Patients with LD-SCLC were treated with SIB-IMRT within 1 week after completion of 2 cycles of induction chemotherapy. Then 2-4 cycles of adjuvant chemotherapy were administered within 1 week after SIB-IMRT. Irradiation was given accelerated hyper-fractionated with the prescribed dose 57Gy at 1.9Gy twice daily to the gross tumor volume (GTV) , 51Gy at 1.7Gy twice daily to the clinical tumor volume (CTV) and 45Gy at 1.5Gy twice daily to the planning target volume (PTV). The chemotherapy regimen consisted of platinum plus etoposide. Prophylactic cranial radiation (25Gy in 10 fractions) was administered to patients who got complete response (CR) or near complete response (nCR). The primary endpoint of this study was the frequency of grade 3 or higher acute non-hematologic treatment-related toxicities. Secondary end points included objective response, overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRFS). RESULTS A cohort of 35 patients were enrolled in the study, the biological equivalent dose (BED) of the GTV in the SIB-IMRT was 59.16Gy. Grade 1, 2, and 3 esophagitis were observed in 11 (31%), 12 (34%), and 6 (17%) patients, respectively; Grade 1 and 2 pneumonitis were observed in 8 (23%) and 4 (11%) patients, respectively. The median OS and PFS of the whole group were 37.7 months and 29.3 months, respectively. The 1- and 2-year OS was 94.1% and 68.5%, respectively. The 1- and 2-year PFS was 76.8% and 40.7%, respectively. The 1- and 2-year LRFS was 87.7% and 73.8%, respectively. CONCLUSIONS SIB-IMRT was feasible and well-tolerated in patients with LD-SCLC, and worth further evaluating in a large prospective clinical trial.

Abstract
BACKGROUND Intensity-modulated radiation therapy (IMRT) with a simultaneous integrated boost (SIB) has improved the local disease control at a variety of anatomic sites. However, little is known about its use in lung cancer, especially in the context of shorter treatment schedules (hypofractionation). We analyzed the feasibility, toxicity, and patterns of failure of this approach for patients with non-small-cell lung cancer (NSCLC) who were not candidates for surgery or standard concurrent chemoradiation therapy. PATIENTS AND METHODS We retrospectively identified 71 patients with NSCLC who received IMRT+SIB in 15 fractions to ≥ 52.5 Gy from January 2007 to February 2013. Toxicity and local control were evaluated for all patients. RESULTS Of the 71 patients, 11 (16%) had stage I to II NSCLC, 15 (21%) stage III, and 45 (63%) stage IV. The esophagitis rate was grade 0 to 1 in 55%, grade 2 in 39%, and grade ≥ 3 in 6%. One patient developed a bronchoesophageal fistula 6 months after radiation. The pneumonitis rate was grade 0 to 1 in 93%, grade 2 in 6%, and grade 3 in 1%. At the time of analysis, 17 (24%) patients had local failure at a median of 5.2 months (range, < 1-16.1) after treatment. All but 1 failure occurred within the higher dose region. CONCLUSION Hypofractionated IMRT+SIB is a viable option for some patients with NSCLC, with little high-grade toxicity overall. Nearly all local failures occurred within the higher dose region, implying strong radioresistance or some other mechanism for recurrence in a subgroup of patients.

Abstract
PURPOSE To evaluate feasibility and outcome of our institutional SIB-IMRT schedule in patients with anal cancer and to selectively review the literature on different SIB-IMRT schedules. PATIENTS AND METHODS Between 01/08-06/13 25 patients with biopsy proven squamous cell anal cancer were treated in our institution with IMRT. Radiotherapy was delivered in two series using a SIB-IMRT schedule of 45 Gy/1.8 Gy to the primary tumor and adjacent pelvic lymph nodes and 38 Gy/1.52 Gy to elective nodes followed by an IMRT boost of 7×2 Gy = 14 Gy to the primary tumor and involved nodes (cumulative prescription dose: 59 Gy). RESULTS Mean follow-up was 20 months (range: 4-68). The 2-year-local control, colostomy-free survival, distant metastases-free survival and overall survival rates were 92%, 92%, 92%, and 88%, respectively. Grade 3 acute skin toxicity was observed in 6 patients (24%). No high grade gastrointestinal or urinary acute toxicity occurred. Four patients required more than one day of treatment interruption due to acute toxicity. No grade 3 or higher late sequelae were observed. CONCLUSION We present our institutional SIB-IMRT experience treating patients with anal cancer in two series using moderate single doses from 1.5-2.0 Gy. Our results, in terms of loco-regional outcome and toxicity, were comparable to other studies. The incidence of treatment interruptions was very low. Therefore this schedule appears to be safe for clinical use.

Abstract
Background: Capecitabine is an established treatment alternative to intravenous 5-fluorouracil (5-FU) for patients with rectal cancer receiving chemoradiotherapy. Its place in the treatment of locally advanced anal carcinoma (AC), however, remains undetermined. We investigated whether capecitabine is as effective as 5-FU in the treatment of patients with locally advanced AC. Methods: One hundred and five patients with squamous cell AC stage T2-4 (T2>4 cm), N0-1, M0 or T1-4, N2-3, M0, were included in this retrospective study. Forty-seven patients were treated with continuous 5-FU (750 mg m−2) on days 1–5 and 29–33, mitomycin C (MMC, 10 mg m−2) on day 1, and radiotherapy; 58 patients were treated with capecitabine (825 mg m−2 b.i.d. on weekdays), MMC (10 mg m−2) on day 1, and radiotherapy. The primary end points of the study were: clinical complete response rate, locoregional control (LRC) and overall survival (OS). Secondary end points were: colostomy-free survival (CFS), toxicity and associations of genetic polymorphisms (GSTT1, GSTM1, GSTP1 and TYMS) with outcome and toxicity. Results: Clinical complete response was achieved in 41/46 patients (89.1%) with 5-FU and in 52/58 patients (89.7%) with capecitabine. Three-year LRC was 76% and 79% (P=0.690, log-rank test), 3-year OS was 78% and 86% (P=0.364, log-rank test) and CFS was 65% and 79% (P=0.115, log-rank test) for 5-FU and capecitabine, respectively. GSTT1 and TYMS genotypes were associated with severe (grade 3–4) toxicity. Conclusions: Capecitabine combined with MMC and radiotherapy was equally effective as 5-FU-based chemoradiotherapy. This study shows that capecitabine can be used as an acceptable alternative to 5-FU for the treatment of AC.

Abstract
SUMMARY Anal cancer is a rare cancer whose incidence is increasing in the UK. It is associated with human papilloma virus infection and smoking and is more common in women and immunosuppressed individuals, including those with transplants and HIV infection. The current standard of care is chemoradiotherapy (CRT) to the pelvis with surgery reserved for patients where CRT is contraindicated or as salvage treatment for residual disease or recurrence post-CRT. Radiotherapy combined with mitomycin-C and 5-fluorouracil has emerged as the standard of care following a series of six well-conducted Phase III trials. Trials have shown no benefit for cisplatin-based combination regimens either concurrently, adjuvantly or neoadjuvantly.
