RESUMO
Anal canal adenocarcinoma is generally treated like rectal cancer. Surgery is the standard treatment in early stages and neoadjuvant chemoradiation in locally advanced tumors. Local recurrences treatment paradigm often depends on the previous therapies of either surgery or radiotherapy or systemic therapy. We present the case of a patient with tubulovillous adenocarcinoma of the anal canal which relapsed after chemoradiation. The patient refused salvage surgery and was treated with definitive electrochemotherapy under general anesthesia. Tumor electroporation performed with the insertion of three needles in the recurred site was preceded by an intravenous bolus of bleomycin. After the administered treatment, the patient showed a complete clinical response. A year after electrochemotherapy, the patient is free from local disease with excellent preservation of the sphincter function. Electrochemotherapy may be considered as an alternative to surgery in small lesion in the anorectal region when other approaches are excluded.

OBJECTIVE: Vaginal metastases are very rare events with a poor prognosis. To improve the quality of life, local treatments should be considered. The aim of this study was to evaluate the role of electrochemotherapy as palliative treatment in vaginal cancer not amenable to standard treatments due to poor performance status, previous treatments, or advanced disease. METHODS: This is a prospective observational study on patients diagnosed with vaginal cancer and treated from January 2017 to December 2018 with palliative electrochemotherapy. We collected data on patients with vaginal cancer treated by electrochemotherapy with the aim of local control. Data regarding electrochemotherapy, hospital stay, adverse events, and patient outcomes were analyzed. Intravenous bleomycin was injected as a bolus in 2-3 min at a dose of 15 000 UI/m2 and electrical pulses started 8 min after chemotherapy. Electrochemotherapy response was defined according to the Response Evaluation Criteria in Solid Tumors. RESULTS: Five patients with vaginal recurrence (two squamous, two melanomas, and one leiomyosarcoma) and one with vaginal metastasis from intestinal adenocarcinoma received one treatment and two patients were re-treated. Imaging reported nodal metastasis (inguinal or pelvic) in two patients, distant metastases in two, and both node and distant metastasis in two patients, respectively. Response Evaluation Criteria in Solid Tumors showed a complete response in one patient, partial response in three patients, stable disease in one patient, and progressive disease in one patient, with an overall response rate of 67% and a clinical benefit rate (complete response, partial response, stable disease) of 83%. Two patients were re-treated and had a new response (partial response and stable disease, respectively). At last follow-up, two patients had died of the disease, two were alive with stable disease, one was alive with progressive disease, and one was alive without disease. Median post-electrochemotherapy overall survival was 12.9 months (range 1.6-26.9) and 1-year overall survival was 66.7%. CONCLUSIONS: This preliminary experience showed a tumor response or stabilization in 83% of patients requiring palliative management for vaginal cancer. Further studies are needed to evaluate treatment outcome in larger and prospective series.

AIM: This study systematically reviews the recent literature on the role of definitive radiotherapy (RT) in the management of vaginal cancer (VC) and presents comprehensive data on clinical outcomes and toxicity. METHODS: The authors performed a literature search using PubMed (2007-2016) to identify all prospective and retrospective studies that have been published on RT in invasive VC. RESULTS: Of the 199 identified studies, 13 met the inclusion criteria. All studies had a retrospective design. Overall, 793 patients (median, 45; range, 26-138) were included. A high heterogeneity was found across studies in terms of RT techniques, assessment criteria, and reported outcomes. The majority of the patients were treated with a combination of external beam RT and brachytherapy (74.2%). Acute and late grade ≥3 toxicity rates ranged from 0.0% to 24.4% (median, 8.7%) and from 0.0% to 22.5% (median, 12.8%), respectively. The 5-year local control rates ranged between 39% and 79%. The 5-year overall survival ranged between 34% and 71.0% (median, 63.5%). Early stage of the disease (International Federation of Gynecology and Obstetrics stages I-II vs. III-IV), small tumor size (<4 cm), previous hysterectomy, high pretreatment/treatment hemoglobin levels (≥12/12.5 mg/dL), and patients' age <70 or <64 years were correlated with better clinical outcomes. CONCLUSION: Only retrospective studies, in a limited number, have been published on RT in VC in the past decade, with significant heterogeneity in terms of treatment characteristic and evaluation criteria. Clinical results were strongly influenced by tumor stage. Prospective randomized studies are needed to improve patients' outcomes, especially in advanced-stage disease. IMPLICATIONS FOR PRACTICE: This study systematically reviews the recent literature on the role of definitive radiotherapy in the management of vaginal cancer and presents comprehensive data on clinical outcome and toxicity. The prognosis of patients is dismal, with a 5-year overall survival of approximately 50%. Early stage of the disease, small tumor size, previous hysterectomy, high pretreatment/treatment hemoglobin levels, and patients' age were correlated with a better clinical outcome. A brachytherapy boost should be delivered, especially in patients with higher-stage disease. The addition of concurrent weekly cisplatin should be considered in most patients, and transfusion should be used to maintain high hemoglobin levels.

BACKGROUND AND OBJECTIVES: Previous studies showed a local tumor control of 80% in patients with relapsed squamous cell vulvar cancer (V-SCC) treated with electrochemotherapy. These results encouraged electrochemotherapy use as neo-adjuvant treatment in V-SCC. The objective of this study was to evaluate the effectiveness of electrochemotherapy in reducing tumor burden in V-SCC. METHODS: Patients with histological diagnosis of primary V-SCC eligible for surgery were enrolled. Following accurate mapping of all the lesions, electrochemotherapy was performed. One month after electrochemotherapy clinical response was evaluated according to RECIST criteria and the type of surgery was confirmed or modified. Adjuvant therapies were prescribed depending on stage and pathological evaluation. RESULTS: We report the results from nine patients treated with electrochemotherapy before surgery. The median age was 64 years (range 51-81 years). Tumor response after electrochemotherapy was observed in seven patients (77.8%) with one CR and six PR, without complications. Tumor downsizing led to more conservative surgery in six patients (66.7%). At a median follow-up of 8 months (range 2-32 months) all patients were alive without disease. CONCLUSIONS: Our preliminary analysis suggests that ECT is a suitable treatment in patients with V-SCC before surgery, reducing the tumor size and the surgical resection.

OBJECTIVE: The aim of this study was to investigate the impact of SUVmax fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) measured in the primary tumor, pelvic and para-aortic node with disease-free survival (DFS) and overall survival (OS) in patients with locally advanced cervical cancer. METHODS AND MATERIALS: A total of 92 patients with histological diagnosis of locally advanced cervical cancer are treated with radiochemotherapy plus brachytherapy boost from January 2008 to April 2014 in our Institution. A pretreatment FDG-PET/CT for staging and radiotherapy planning was performed, and the value of SUVmax measured in primary tumor and positive nodes was related to DFS and OS. RESULTS: Univariate analysis showed that DFS is related to FDG-PET/CT positive para-aortic nodes (P = 0.01), International Federation of Gynecology and Obstetrics (FIGO) stage of disease (P = 0.01), and primary tumor SUVmax (P = 0.02), and OS is related to positive para-aortic nodes (P = 0.01) and primary tumor SUVmax (P = 0.02).In multivariate analysis, DFS is modified by FDG-PET/CT positive para-aortic lymph nodes, stage and high T SUVmax (P = 0.02; P = 0.003; P = 0.04), but the only worse prognostic factor of OS is the high SUVmax in the primary tumor (P = 0.01). CONCLUSIONS: We found that T SUVmax, stage, and para-aortic lymph node status assessed by FDG-PET were independent prognostic factors of DFS, whereas only T SUVmax correlated with OS.

OBJECTIVE: The primary endpoint of this trial was to assess clinical response (cCR) of squamocellular vulvar cancer (V-SCC) in elderly patients treated with electro-chemotherapy (ECT). Secondary endpoints were symptoms relief and local tumor control. METHODS: A phase II study was designed and elderly patients with V-SCC unfit for other treatments were treated. Response Evaluation Criteria in Solid Tumors (RECIST criteria) were applied to evaluate tumor response. Quality of life (QoL) was evaluated by visual analogue score (VAS) for pain and four items of vulvar cancer subscale (VCS), of functional assessment of vulvar cancer therapy (FACT-V) [16], before, one month after the procedure and during follow-up. RESULTS: Median age was 85 years (range 66-96 years). One month after treatment complete response was observed in 13 patients (52%), partial response in 7 (28%), stable disease in 3 (12%), and progressive disease in 2 (8%). Local tumor control at 1 and 6 months was 91% and 53%, respectively. Symptom free survival at 1 and 6 months was 78% and 40%, respectively, with significant reduction of pain (P < 0.01). One-year overall survival was 34%. CONCLUSIONS: Our study showed that ECT produces high response rate with significant reduction of pain and improvement of local symptoms.

Objective: Squamous cell carcinoma of the nasal vestibule (NV SCC) is a head and neck malignancy for which there is no established consensus on most aspects of clinical management. The purpose of this document is to give updated recommendations that incorporate recent evidence on its clinical characteristics and the high efficacy of brachytherapy as primary treatment modality. Methods: A working group consisting of the members of the Scientific Committee for Oncology and Reconstructive Surgery of the Italian Society of Otorhinolaryngology Head and Neck Surgery and radiation oncologists expert in brachytherapy was formed to achieve a consensus. Results: Consensus was reached on a set of recommendations, proposing a refined anatomical definition of the nasal vestibule, a novel T staging system of the NV SCC, and brachytherapy as standard of care, with a new method for catheter implantation. Conclusions: The Committee emphasises the critical role of an accurate classification in clinical practice and encourages further research to validate the novel staging system and further improve treatment strategies. Where appropriate, it is recommended that patients be referred to centres with specific experience in brachytherapy for NV SCC.

OBJECTIVE: Electrochemotherapy (ECT) is an attractive treatment for solid cutaneous tumours with a good response rate (55-92%). No studies have evaluated ECT performed in vulvar cancer. The aim of our study was to evaluate the safety, local tumour efficacy and relief of symptoms of ECT treatment in patients affected by recurrence of squamocellular vulvar cancer (V-SCC) unsuitable for standard treatments. METHODS: We enrolled nine patients with histological diagnosis of recurrence of V-SCC. Intravenous bleomycin was injected under general sedation after an accurate mapping of all lesions and ECT was performed. Patients were reviewed after one, three and six months. Response to therapy was evaluated using RECIST criteria and quality of life (QoL) was evaluated via questionnaires. RESULTS: The median age was 84 years (range 80-90 years). The main location of recurrences was the vulva (87.5%). Multiple lesions were present in 25% of cases. No peri-operative complications were observed. Response to therapy was complete in 62.5% of patients, partial in 12.5%, no change was observed in 12.5% and progression of disease in 12.5% of patients respectively. Evaluation of symptoms showed a significant reduction of pain, bleeding, odour (p < 0.04) and urinary discomfort (p < 0.04). We observed two relapses at four and seven months after treatment. After nine months fifty percent of patients were alive. CONCLUSIONS: Our preliminary study showed that ECT is a suitable procedure in elderly patients with loco-regional vulvar cancer relapses. ECT can be used as palliative therapy and the treatment relieves symptoms and improves QoL.

(1) Background: Biliary tract cancers (BTCs) are a heterogeneous group of neoplasms with dismal prognosis and the role of adjuvant chemoradiotherapy in high-risk resected patients is unclear. (2) Methods: We retrospectively analyzed the outcomes of BTC patients who received curative intent surgery with microscopically positive resection margins (R1) and adjuvant chemoradioradiotherapy (CCRT) or chemotherapy (CHT) from January 2001 to December 201. (3) Results: Out of 65 patients who underwent R1 resection, 26 received adjuvant CHT and 39 adjuvant CCRT. The median recurrence-free survival (RFS) in the CHT and CHRT groups was 13.2 and 26.8 months, respectively (p = 0.41). Median overall survival (OS) was higher in the CHRT group (41.9 months) as compared to the CHT group (32.2 months), but the difference was not statistically significant (HR 0.88; p = 0.7). A promising trend in favor of CHRT was observed in N0 patients. Finally, no statistically significant differences were observed between patients undergoing adjuvant CHRT after R1 resection and patients treated with chemotherapy alone after R0 surgery. (4) Conclusions: Our study did not show a significant survival benefit with adjuvant CHRT over CHT alone in BTC patients with positive resection margins, while a promising trend was observed.

Systemic inflammation indices were found to be correlated with therapeutic outcome in several cancers. This study retrospectively analyzes the predictive role of a broad range of systemic inflammatory markers in patients with locally advanced cervical cancer (LACC) including patient-, tumor-, and treatment-related potential prognostic factors. All patients underwent definitive chemoradiation and pretreatment values of several inflammatory indices (neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio, monocyte/lymphocyte ratio, systemic immune inflammation index (SII), leukocyte/lymphocyte ratio, combination of platelet count and NLR, aspartate aminotransferase/platelet ratio index, aspartate aminotransferase/lymphocyte ratio index, systemic inflammatory response index, and aspartate transaminase/neutrophil ratio index) were calculated. Their correlation with local control (LC), distant metastasis-free (DMFS), disease-free (DFS), and overall survival (OS) was analyzed. One hundred and seventy-three patients were included. At multivariable analysis significant correlations were recorded among clinical outcomes and older age, advanced FIGO stage, lower hemoglobin levels, larger tumor size, and higher body mass index values. The multivariate analysis showed only the significant correlation between higher SII values and lower DMFS rates (p < 0.01). Our analysis showed no significant correlation between indices and DSF or OS. Further studies are needed to clarify the role of inflammation indices as candidates for inclusion in predictive models in this clinical setting.
RESUMO
Background: A CE- and FDA-approved cloud-based Deep learning (DL)-tool for automatic organs at risk (OARs) and clinical target volumes segmentation on computer tomography images is available. Before its implementation in the clinical practice, an independent external validation was conducted. Methods: At least a senior and two in training Radiation Oncologists (ROs) manually contoured the volumes of interest (VOIs) for 6 tumoral sites. The auto-segmented contours were retrieved from the DL-tool and, if needed, manually corrected by ROs. The level of ROs satisfaction and the duration of contouring were registered. Relative volume differences, similarity indices, satisfactory grades, and time saved were analyzed using a semi-automatic tool. Results: Seven thousand seven hundred sixty-five VOIs were delineated on the CT images of 111 representative patients. The median (range) time for manual VOIs delineation, DL-based segmentation, and subsequent manual corrections were 25.0 (8.0-115.0), 2.3 (1.2-8) and 10.0 minutes (0.3-46.3), respectively. The overall time for VOIs retrieving and modification was statistically significantly lower than for manual contouring (p<0.001). The DL-tool was generally appreciated by ROs, with 44% of vote 4 (well done) and 43% of vote 5 (very well done), correlated with the saved time (p<0.001). The relative volume differences and similarity indexes suggested a better inter-agreement of manually adjusted DL-based VOIs than manually segmented ones. Conclusions: The application of the DL-tool resulted satisfactory, especially in complex delineation cases, improving the ROs inter-agreement of delineated VOIs and saving time.
RESUMO
Introduction: The European Society of Gynecologic Oncology/European Society of Radiation Therapy and Oncology/European Society of Pathology (ESGO/ESTRO/ESP) committee recently proposed a new risk stratification system for endometrial carcinoma (EC) patients that incorporates clinicopathologic and molecular features. The aim of the study is to compare the new ESGO/ESTRO/ESP risk classification system with the previous 2016 recommendations, evaluating the impact of molecular classification and defining a new algorithm for selecting cases for molecular analysis to assign the appropriate risk class. Methods: The cohort included 211 consecutive EC patients. Immunohistochemistry and next-generation sequencing were used to assign molecular subgroups of EC: POLE mutant (POLE), mismatch repair deficient (MMRd), p53 mutant (p53abn), and no specific molecular profile (NSMP). Results: Immuno-molecular analysis was successful in all cases, identifying the four molecular subgroups: 7.6% POLE, 32.2% MMRd, 20.9% p53abn, and 39.3% NSMP. The recent 2020 guidelines showed a 32.7% risk group change compared with the previous 2016 classification system: the reassignment is due to POLE mutations, abnormal p53 expression, and a better definition of lymphovascular space invasion. The 2020 system assigns more patients to lower-risk groups (42.2%) than the 2016 recommendation (25.6%). Considering the 2020 risk classification system that includes the difference between "unknown molecular classification" and "known," the integration of molecular subgroups allowed 6.6% of patients to be recategorized into a different risk class. In addition, the use of the proposed algorithm based on histopathologic parameters would have resulted in a 62.6% reduction in molecular analysis, compared to applying molecular classification to all patients. Conclusion: Application of the new 2020 risk classification integrating clinicopathologic and molecular parameters provided more accurate identification of low-and high-risk patients, potentially allowing a more specific selection of patients for post-operative adjuvant therapy. The proposed histopathologic algorithm significantly decreases the number of tests needed and could be a promising tool for cost reduction without compromising prognostic stratification.
RESUMO
The main treatment of MM metastases are systemic therapies, surgery, limb perfusion, and intralesional talimogene laherparepvec. Electrochemotherapy (ECT) is potentially useful also due to the high response rates recorded in cancers of any histology. No randomized studies comparing ECT with other local therapies have been published on this topic. We analyzed the available evidence on efficacy and toxicity of ECT in this setting. PubMed, Scopus, and Cochrane databases were screened for paper about ECT on MM skin metastases. Data about tumor response, mainly in terms of overall response rate (ORR), toxicity (both for ECT alone and in combination with systemic treatments), local control (LC), and overall survival (OS) were collected. The methodological quality was assessed using a 20-item validated quality appraisal tool for case series. Overall, 18 studies were included in our analysis. In studies reporting "per patient" tumor response the pooled complete response (CR) was 35.7% (95%CI 26.0-46.0%), and the pooled ORR was 80.6% (95%CI 68.7-90.1%). Regarding "per lesion" response, the pooled CR was 53.5% (95%CI 42.1-64.7%) and the pooled ORR was 77.0% (95%CI 56.0-92.6%). One-year LC rate was 80%, and 1-year OS was 67-86.2%. Pain (24.2-92.0%) and erythema (16.6-42.0%) were the most frequent toxicities. Two studies reported 29.2% and 41.6% incidence of necrosis. ECT is effective in terms of tumor response and tolerated in patients with skin metastases from MM, albeit with a wide variability of reported results. Therefore, prospective trials in this setting are warranted.

INTRODUCTION: Data in literature about the use of adjuvant treatment to reduce acute adverse effects of radiotherapy on the pelvis are scant, with the exception of a few reports on the topical use of estrogen, which promotes proliferation of epithelium. MATERIALS AND METHODS: In this prospective trial, α-tocopherol acetate was topically administered to patients affected by endometrial and cervical cancer and undergoing radiation treatment to avoid acute vaginal complications. RESULTS: Vaginal application of α-tocopherol reduced vaginal toxicity and pain, although vaginal secretion was not significantly different in the 2 groups studied. The histological scoring system showed a significant reduction of inflammation, no difference in fibrosis, and an increase of acanthosis. CONCLUSIONS: The use of α-tocopherol as adjuvant treatment to reduce the acute adverse effects of radiotherapy on the vagina should be considered.

The ELECHTRA (ELEctroChemoTherapy vulvaR cAncer) project was conceived to collect data on palliative electrochemotherapy (ECT) in vulvar cancer (VC) assessing patients' outcomes (response and survival) and impact on quality of life (QoL). After reporting outcome data in 2019, here, we present the results on QoL. A multicenter prospective observational study was conducted on patients with VC refractory or not amenable to standard therapies undergoing palliative ECT as per clinical practice. The following questionnaires were administered before and after ECT (two and four months later, early and late follow-up): visual analog pain scale (VAS), EuroQol 5-Dimension 5-Level (EQ-5D-L5) and Functional Assessment of Cancer Therapy-Vulva cancer (FACT-V). Analyses were conducted on both the whole study population and by subgroups (clinical response after ECT and site, number and size of lesions). Questionnaires from 55 patients were evaluated. Compared to the baseline (6.1 ± 2.1), the VAS was significantly reduced at early (4.3 ± 2.5) and late follow-up (4.6 ± 2.8) (p < 0.0001). The FACT-V score improved significantly at early (9.6 ± 4.0) (p < 0.0001) and late follow-up (8.9 ± 4.1) (p < 0.0054) as compared to the baseline (7.1 ± 3.6). No EQ-5D-5L statistically significant changes were observed. Subgroup analyses showed worse QoL in patients with stable or progressive disease, posterior site and multiple or larger than 3 cm nodules. This is the first study reporting improved QoL in VC patients after palliative ECT. Based on these results, ECT in VC should be considered an effective option based on the favorable outcomes both in terms of response and QoL.
RESUMO
Kaposi sarcoma (KS) is a rare angioproliferative disorder, which is usually associated with human herpesvirus-8 infection. Electrochemotherapy (ECT) may be an option in the treatment of KS skin lesions due to the high response rate noted in neoplastic lesions of different histological types. The aim of the present systematic review was to analyse the available evidence on using ECT in the treatment of KS skin lesions. Tumor response, local control and toxicity were analyzed. In the three included studies, the complete response rate was 65-100% and the overall response rate in all studies was 100%. The treatment was well tolerated with mild and transient toxicity. However, further studies are required to fully analyze long-term disease control and to compare ECT with other local therapies used for KS.
RESUMO
BACKGROUND: In our department, we provided guidelines to the radiation oncologists (ROs) regarding the omission, delay, or shortening of radiotherapy (RT). The purpose was to reduce the patients' exposure to the hospital environment and to minimize the departmental overcrowding. The aim was to evaluate the ROs' compliance to these guidelines. METHODS: ROs were asked to fill out a data collection form during patients' first visits in May and June 2020. The collected data included the ROs' age and gender, patient age and residence, RT purpose, treated tumor, the dose and fractionation that would have been prescribed, and RT changes. The chi-square test and binomial logistic regression were used to analyze the correlation between the treatment prescription and the collected parameters. RESULTS: One hundred and twenty-six out of 205 prescribed treatments were included in this analysis. Treatment was modified in 61.1% of cases. More specifically, the treatment was omitted, delayed, or shortened in 7.9, 15.9, and 37.3% of patients, respectively. The number of delivered fractions was reduced by 27.9%. A statistically significant correlation (p = 0.028) between younger patients' age and lower treatment modifications rate was recorded. CONCLUSION: Our analysis showed a reasonably high compliance of ROs to the pandemic-adapted guidelines. The adopted strategy was effective in reducing the number of admissions to our department.

Tumor response in locally advanced cervical cancer (LACC) is generally evaluated with MRI and PET, but this strategy is not supported by the literature. Therefore, we compared the diagnostic performance of these two techniques in the response evaluation to concurrent chemoradiotherapy (CCRT) in LACC. Patients with cervical cancer (CC) stage T2b treated with CCRT and submitted to MRI and PET/CT before and after treatment were enrolled in the study. All clinical, pathological, therapeutic, radiologic and follow-up data were collected and examined. The radiological response was analyzed and compared to the follow-up data. Data of 40 patients with LACC were analyzed. Agreement between MRI and PET/CT in the evaluation response to therapy was observed in 31/40 (77.5%) of cases. The agreement between MRI, PET/CT and follow-up data showed a Cohen kappa coefficient of 0.59 (95% CI = 0.267-0.913) and of 0.84 (95% CI = 0.636-1.00), respectively. Considering the evaluation of primary tumor response, PET/CT was correct in 97.5% of cases, and MRI in 92.5% of cases; no false negative cases were observed. These results suggest the use of PET/CT as a unique diagnostic imaging tool after CCRT, to correctly assess residual and progression disease.
RESUMO
Women who have previously received radiotherapy (RT) for gynecologic cancer often suffer from vaginal fibrosis and stenosis. The success of "non-ablative" laser therapy for postmenopausal vaginal atrophy has led to the idea of testing the laser in patients submitted to RT. In this prospective observational study, we selected patients who underwent pelvic RT followed by vaginal laser treatment. We scheduled three treatment sessions (at T0-T1-T2) and three controls (at T1-T2-T3) one month apart. The follow-up (at T4) was carried out six months after the last treatment. Vaginal Health Index (VHI) and vaginal length were evaluated. Sexual function was assessed through Female Sexual Function Index (FSFI). Overall, 43 patients with severe vaginal shortening, atrophy and stenosis was enrolled and treated with intravaginal non-ablative CO2 laser. We observed a progressive increase in vaginal length of 9% (p = 0.03) at T2 and 28% (p < 0.0001) at T3; effects were maintained at T4 (p < 0.0001). After the first application VHI showed a significant improvement of 57% at T3 (p < 0.0001). The results were maintained at T4 (p < 0.0001). No changes were found in FSFI. All procedures were well tolerated. In conclusion, laser therapy improved vaginal length and VHI in women undergoing pelvic RT; prospective studies are needed.
RESUMO
PURPOSE: Concurrent chemoradiation (CCRT) is the standard curative treatment of anal canal cancer (ACC). The role of a brachytherapy (BRT) boost in this setting is still debated. Therefore, the aim of this analysis was to retrospectively evaluate the clinical outcomes in a large cohort of ACC patients treated with CCRT plus BRT boost or external beam radiotherapy (EBRT) boost. MATERIAL AND METHODS: Patients with non-metastatic ACC, treated in our department between January 2003 and December 2014 were included in this analysis. The initial treatment was based on EBRT to the pelvis (prescribed dose, 45 Gy/1.8 Gy) plus concurrent chemotherapy (5-fluorouracil and mitomycin-C). Patients received a pulsed-dose-rate BRT boost on the primary tumor (median dose, 20 Gy; range, 13-25 Gy) 2-3 weeks after the end of CCRT. In patients with contraindications to BRT, an EBRT boost (prescribed dose, 16 Gy, 2 Gy/fraction) was delivered immediately after CCRT. RESULTS: One-hundred-twenty-three patients were included in this analysis (median age, 61 years; range, 36-93 years; squamous-cell carcinoma, 78%; HIV+, 6%; median follow-up, 71 months; range, 2-158 months). The actuarial 5-year local control (LC), distant metastasis-free survival, colostomy-free survival, and overall survival (OS) rates were 81.7%, 92.3%, 62.3%, and 74.0%, respectively. At univariate analysis, patients aged ≤ 65 years (p < 0.010), cT1-2 stage (p = 0.004), and receiving a BRT boost (p = 0.015) showed significantly improved OS. At multivariate analysis, advanced tumor stage cT3-cT4 (HR, 2.12; 95% CI: 1.09-4.14; p = 0.027), and age > 65 years (HR, 3.03; 95% CI: 1.54-5.95; p = 0.001) significantly predicted increased risk of mortality. The crude rate of toxicity-related colostomies was 4.9%. CONCLUSIONS: The role of BRT boost in ACC remains unclear since the outcomes were not clearly different compared to CCRT alone. However, further improvement of clinical results in ACC treatment is needed, and therefore prospective trials based on advanced (image-guided/adapted) BRT techniques are warranted.
