RESUMO
Skin damage is the most common and most important toxicity during and after radiation therapy (RT). Its assessment and understanding of the factors influencing its occurrence, is a major issue in the management of patients irradiated for an early breast cancer. CANTO is a prospective clinical cohort study of 10 150 patients with stage I-III BC treated from 2012 to 2017 in 26 cancer centres. In our study, we used CANTO-RT, a subcohort of CANTO, including 3480 patients who received RT. We are focus on specific skin toxicities: erythema, fibrosis, telangiectasia and cutaneous pigmentation. The prevalence of toxicities of interest varied over time, so at baseline for early toxicity Month (M) 0-3-6, 41.1% of patients had erythema while 24.8% of patients had fibrosis. At M12 and M36, the prevalence of erythema decreased, respectively, while fibrosis remains stable. The prevalence of telangiectasia increases from 1% to 7.1% from M0-3-6 to M36. After adjustments, we showed an association between the occurrence of skin erythema and obesity; the type of surgery; the presence of axillary dissection; the use of taxane-based CT and the 3D vs IMRT irradiation technique. Regarding fibrosis, an association is found, at M0-3-6, with age at diagnosis, obesity, tobacco and the use of boost. Only obesity and the type of surgery received by the patient remained statistically significant at M12 and M36. In our study we identified several risk factors for acute and late skin reactions. The use of a boost was mainly related to the occurrence of fibrosis while the use of IMRT-type technique decreased the occurrence of skin erythema.

PURPOSE: To describe the quality assurance (QA) program and early toxicities in the phase III randomized trial BONBIS (NCT00907868) on the role of a localized radiation boost in ductal carcinoma in situ (DCIS). MATERIALS AND METHODS: From November 2008 to July 2014, 2004 patients were randomized in arm A (only whole breast radiotherapy, WBRT) and arm B (WBRT + boost). The QA program involved 44 participant centers that performed the dummy run (DR). Compliance and uniformity of clinical target volume (CTV) delineations, and dose prescription and delivery according to the BONBIS trial radiotherapy guidelines were analyzed. Acute toxicities (during and up to 3 months after radiotherapy completion, NCI-CTCAE v3.0 classification) were evaluated in 1929 patients. RESULTS: The differences in whole breast CTV (CTV1) and planning target volume (PTV1) were ≤10%, and the differences in boost CTV (CTV2) and PTV (PTV2) were ≥20% compared with the reference DR values; 95% of the prescribed dose encompassed 98.7% and 100% of the median CTV1 and CTV2. Grade ≥2 breast erythema (38.3% vs. 22.4% of grade 2 and 5.4% vs. 2.1% of grade 3, p < 0.001), grade ≥2 dermatitis (2.8% vs. 0.7%, p < 0.001), and grade 2 hyperpigmentation (6.9% vs. 3.6%, p = 0.005) were more frequent in arm B than arm A. No acute lung or cardiac toxicity was observed. Smoking history, large breast size, and large breast CTV were strong predictive factors of grade ≥2 acute skin toxicities. CONCLUSIONS: The QA program showed deviations in breast and tumor bed delineation. The boost significantly increased acute skin toxicities.

OBJECTIVE: To evaluate recurrence and early postoperative complications (sepsis) following surgical excision combined with radiotherapy for troublesome hip heterotopic ossification in patients with spinal cord injury and traumatic brain injury. DESIGN: Retrospective case-control study. SETTING: Data relating to patients with spinal cord injury or traumatic brain injury who underwent surgical excision of hip heterotopic ossification were retrieved from the BANKHO database. Case patients underwent excision + radiotherapy and controls underwent excision only. Control patients were matched to case patients according to sex and age (± 4 years). PARTICIPANTS: Data from 19 case patients and 76 controls were analysed. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The primary end-point was recurrence of heterotopic ossification. Secondary end-points were postoperative complications and, more specifically, sepsis that required surgical revision. RESULTS: There was no difference between the odds ratios (OR) for recurrence for each group (OR case group = 0.63, OR spinal cord injury subgroup = 0.45 and OR head injury subgroup = 1.04). The rate of sepsis requiring surgical revision was significantly higher in the case group (p < 0.05). CONCLUSION: Based on the results of this case-control study, we suggest that radiotherapy should not be combined with surgery in patients with troublesome hip heterotopic ossification undergoing excision. Radiotherapy does not appear to prevent recurrence and, moreover, it is associated with an increased risk of postoperative sepsis.

BACKGROUND: A better understanding of the molecular profile of anal squamous cell carcinomas (ASCCs) is necessary to consider new therapeutic approaches, and the identification of prognostic and predictive factors for response to treatment. METHODS: We retrospectively analysed tumours from ASCC patients for mutational analysis of KRAS, NRAS, HRAS, BRAF, PIK3CA, MET, TP53 and FBXW7 genes by HRM and Sanger sequencing analysis. RESULTS: Specimens from 148 patients were analysed: 96 treatment-naive tumours and 52 recurrences after initial radiotherapy (RT) or chemoradiotherapy (CRT). Mutations of KRAS, PIK3CA, FBXW7 and TP53 genes were present in 3 (2.0%), 30 (20.3%), 9 (6.1%) and 7 tumours (4.7%), respectively. The distribution of the mutations was similar between treatment-naive tumours and recurrences, except for TP53 mutations being more frequent in recurrences (P=0.0005). In patients treated with abdominoperineal resection (APR) after relapse (n=38, median follow-up of 18.2 years), overall survival (OS) was significantly correlated with HPV16 status (P=0.048), gender (P=0.045) and PIK3CA mutation (P=0.037). The PIK3CA status retained its prognostic significance in Cox multivariate regression analysis (P=0.025). CONCLUSIONS: Our study identified PIK3CA mutation as an independent prognostic factor in patients who underwent APR for ASCC recurrence, suggesting a potential benefit from adjuvant treatment and the evaluation of targeted therapies with PI3K/Akt/mTor inhibitors in PIK3CA-mutated patients.

Squamous cell carcinomas of the anal canal are generally diagnosed at a localized or locally advanced stage and only 5% are metastatic at the time of diagnosis. Advanced forms are therefore much rarer than localized forms and usually correspond to metachronous metastases of initially localized disease. Systemic chemotherapy is indicated for the treatment of both localized disease, in combination with radiotherapy, and metastatic disease. The purpose of this article is to define the current indications and modalities of chemotherapy in the treatment of these cancers based on a review of the published data and in the light of available guidelines.

PURPOSE: To determine whether Ki67 expression and breast cancer subtypes could predict locoregional recurrence (LRR) and influence the postmastectomy radiotherapy (PMRT) decision in breast cancer (BC) patients with pathologic negative lymph nodes (pN0) after modified radical mastectomy (MRM). METHODS AND MATERIALS: A total of 699 BC patients with pN0 status after MRM, treated between 2001 and 2008, were identified from a prospective database in a single institution. Tumors were classified by intrinsic molecular subtype as luminal A or B, HER2+, and triple-negative (TN) using estrogen, progesterone, and HER2 receptors. Multivariate Cox analysis was used to determine the risk of LRR associated with intrinsic subtypes and Ki67 expression, adjusting for known prognostic factors. RESULTS: At a median follow-up of 56 months, 17 patients developed LRR. Five-year LRR-free survival and overall survival in the entire population were 97%, and 94.7%, respectively, with no difference between the PMRT (n=191) and no-PMRT (n=508) subgroups. No constructed subtype was associated with an increased risk of LRR. Ki67 >20% was the only independent prognostic factor associated with increased LRR (hazard ratio, 4.18; 95% CI, 1.11-15.77; P<.0215). However, PMRT was not associated with better locoregional control in patients with proliferative tumors. CONCLUSIONS: Ki67 expression but not molecular subtypes are predictors of locoregional recurrence in breast cancer patients with negative lymph nodes after MRM. The benefit of adjuvant RT in patients with proliferative tumors should be further investigated in prospective studies.

To develop a specific prognostic score for patients with brain metastases (BM) from breast cancer (BC), including the BC molecular subtype and treatment parameters, we analyzed the outcome of 130 patients with BM from BC who received whole-brain radiotherapy. We identified hierarchical risk groups for estimated survival by using recursive partitioning analysis (RPA). Seven prognostic factors, namely performance status, age, trastuzumab-based therapy for HER-2-overexpressing tumors, a triple-negative phenotype, Scarff-Bloom-Richardson grade, the serum LDH level and the lymphocyte count at BM diagnosis, were incorporated in the RPA. The final RPA nodes were grouped according to the survival time. The RPA tree showed that survival was best (median 19.5 months) among patients with HER2-overexpressing tumors who received trastuzumab-based therapy. The worst survival (median 3.5 months) was observed among patients who did not receive trastuzumab and who had lymphopenia at BM diagnosis, or KPS <70 and age over 50 years, or KPS ≥70 and a triple-negative tumor (HR- & HER-2-). The other patients had a median survival of 12.5 months (P < 0.001). This 3-class specific prognostic score successfully predicted the outcomes of a heterogeneous group of patients with brain metastases from BC.

PURPOSE: To evaluate the effect of postmastectomy radiotherapy (PMRT) in Stage II-III breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy (NAC). PATIENTS AND MATERIALS: Of 1,054 breast cancer patients treated with NAC at our institution between 1990 and 2004, 134 had pN0 status after NAC and mastectomy. The demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The effect of PMRT on locoregional recurrence-free survival and overall survival (OS) was evaluated by multivariate analysis, including known prognostic factors. RESULTS: Of the 134 eligible patients, 78 (58.2%) received PMRT and 56 (41.8%) did not. At a median follow-up time of 91.4 months, the 5-year locoregional recurrence-free survival and OS rate was 96.2% and 88.3% with PMRT and 92.5% and 94.3% without PMRT, respectively (p = NS). The corresponding values at 10 years were 96.2% and 77.2% with PMRT and 86.8% and 87.7% without PMRT (p = NS). On multivariate analysis, PMRT had no effect on either locoregional recurrence-free survival (hazard ratio, 0.37; 95% confidence interval, 0.09-1.61; p = .18) or OS (hazard ratio, 2.06; 95% confidence interval, 0.71-6; p = .18). This remained true in the subgroups of patients with clinical Stage II or Stage III disease at diagnosis. A trend was seen toward poorer OS among patients who had not had a pathologic complete in-breast tumor response after NAC (hazard ratio, 6.65; 95% confidence interval, 0.82-54.12; p = .076). CONCLUSIONS: The results from the present retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence, or death when PMRT was omitted in breast cancer patients with pN0 status after NAC and mastectomy. Whether the omission of PMRT is acceptable for these patients should be addressed prospectively.

BACKGROUND: To access the prognostic significance of HER-2 overexpression, the effect of trastuzumab and the cause of death in patients with brain metastases (BM) from breast cancer (BC). METHODS: We analyzed the outcome of 130 patients with BM from BC who received whole-brain radiotherapy (WBRT) (without surgery or radiosurgery) between January 1998 and April 2006. Demographic data, tumor characteristics, and treatments were prospectively recorded. The impact of HER-2 overexpression and trastuzumab-based therapy on overall survival (OS) and the cause of death were evaluated. RESULTS: The median follow-up for the whole population was 6.25 months (mean: 9.15; range: 0.23-53). The median survival time and 1-year survival rates after BM diagnosis were 7.43 months and 35.8% (95% CI: 28-45.7) respectively. The median survival time for HER-2 negative patients (n = 78), HER-2 positive patients not treated with trastuzumab (n = 20) and HER-2 positive patients treated with trastuzumab (n = 32) were 5.9 months, 5.6 months and 19.53 months, respectively. The 1-year survival rates were 26.1%, 29.2% and 62.6% respectively, (p < 0.004). Among the 18 HER-2 positive patients treated with trastuzumab who died, 11 (61%) apparently succumbed from CNS progression, in the face of stable or responsive non-CNS disease. Trastuzumab-based therapy was associated with a 51% reduction in the risk of death (multiadjusted hazard ratio: 0.49; 95% CI, 0.29-0.83). CONCLUSIONS: In our experience, trastuzumab-based therapy for HER-overexpressing tumors was associated with improved survival in BM BC patients. This subgroup of patients may benefit from innovative approaches, in order to obtain better intra cerebral control.

PURPOSE: Neoadjuvant chemotherapy (NAC) generally induces significant changes in the pathologic extent of disease. This potential down-staging challenges the standard indications of adjuvant radiation therapy. We assessed the utility of lymph node irradiation (LNI) in breast cancer (BC) patients with pathologic N0 status (pN0) after NAC and breast-conserving surgery (BCS). METHODS AND MATERIALS: Among 1,054 BC patients treated with NAC in our institution between 1990 and 2004, 248 patients with clinical N0 or N1 to N2 lymph node status at diagnosis had pN0 status after NAC and BCS. Cox regression analysis was used to identify factors influencing locoregional recurrence-free survival (LRR-FS), disease-free survival (DFS), and overall survival (OS). RESULTS: All 248 patients underwent breast irradiation, and 158 patients (63.7%) also received LNI. With a median follow-up of 88 months, the 5-year LRR-FS and OS rates were respectively 89.4% and 88.7% with LNI and 86.2% and 92% without LNI (no significant difference). Survival was poorer among patients who did not have a pathologic complete primary tumor response (hazard ratio, 3.05; 95% confidence interval, 1.17-7.99) and in patients with N1 to N2 clinical status at diagnosis (hazard ratio = 2.24; 95% confidence interval, 1.15-4.36). LNI did not significantly affect survival. CONCLUSIONS: Relative to combined breast and local lymph node irradiation, isolated breast irradiation does not appear to be associated with a higher risk of locoregional relapse or death among cN0 to cN2 breast cancer patients with pN0 status after NAC. These results need to be confirmed in a prospective study.

PURPOSE: Several studies suggest that surgical excision of the primary tumor improves survival among patients with stage IV breast cancer at diagnosis. Exclusive locoregional radiotherapy (LRR) is an alternative form of locoregional treatment (LRT) in this setting. We retrospectively studied the impact of LRT on the survival of breast cancer patients with synchronous metastases. PATIENTS AND METHODS: Among 18,753 breast cancer patients treated in our institution between 1980 and 2004, 598 patients (3.2%) had synchronous metastasis at diagnosis. Demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The impact of LRT on overall survival (OS) was evaluated by multivariate analysis including known prognostic factors. RESULTS: Among 581 eligible patients, 320 received LRT (group A), and 261 received no LRT (group B). LRT consisted of exclusive LRR in 249 patients (78%), surgery of the primary tumor with adjuvant LRR in 41 patients (13%), and surgery alone in 30 patients (9%). With a median follow-up time of 39 months, the 3-year OS rates were 43.4% and 26.7% in group A and group B (P =.00002), respectively. The association between LRT and improved survival was particularly marked in women with visceral metastases. LRT was an independent prognostic factor in multivariate analysis (hazard ratio [HR] = 0.70; 95% CI, 0.58 to 0.85; P = .0002). The adjusted HR for late death (>or= 1 year) was 0.76 (95% CI, 0.61 to 0.96; P = .02). CONCLUSION: In our experience, LRT, consisting mainly of exclusive LRR, was associated with improved survival in breast cancer patients with synchronous metastases. Exclusive LRR may thus represent an active alternative to surgery.

BACKGROUND: The use of a single MRI and 18F-fluoro deoxyglucose positron emission tomography-CT (18F-FDG PET-CT) was evaluated, both in diagnostic procedure and radiotherapy planning, in patients with head and neck cancer. METHODS: Thirty-five patients with nasopharyngeal and oropharyngeal tumors were studied. The MRI and 18F-FDG PET-CT were used for both diagnostic work-up and gross tumor volume and critical structure delineation. The interobserver variation (IOV) of volumes determined on MRI and CT by a radiotherapist and by a radiologist were compared as well as their impact on dose distribution. RESULTS: The CT-MRI decreased the IOV of parotid glands in 12 of 35 and target volume in 15 of 35 patients. The use of 18F-FDG PET-CT changed the treatment design in 6 of 21 patients. CONCLUSIONS: Diagnostic imaging performed in the treatment position can improve the accuracy of radiotherapy planning in case of intracranial tumor extension, heavy dental work, or contraindication for contrast-enhanced CT, but not in the absence of these conditions.

PURPOSE: To validate the Radiation Therapy Oncology Group Recursive Partitioning Analysis (RTOG RPA) classification and determine independent prognostic factors, to create a simple and specific prognostic score for patients with brain metastases (BM) from breast carcinoma treated with whole-brain radiotherapy (WBRT). METHODS AND MATERIALS: From January 1998 through December 2003, 132 patients with BM from breast carcinoma were treated with WBRT. We analyzed several potential predictors of survival after WBRT: age, Karnofsky performance status, RTOG-RPA class, number of BM, presence and site of other systemic metastases, interval between primary tumor and BM, tumor hormone receptor (HR) status, lymphocyte count, and HER-2 overexpression. RESULTS: A total of 117 patients received exclusive WBRT and were analyzed. Median survival with BM was 5 months. One-year and 2-year survival rates were 27.6% (95% confidence interval [CI] 19.9-36.8%) and 12% (95% CI 6.5-21.2%), respectively. In multivariate analysis, RTOG RPA Class III, lymphopenia (< or =0.7 x 10(9)/L) and HR negative status were independent prognostic factors for poor survival. We constructed a three-factor prognostic scoring system that predicts 6-month and 1-year rates of overall survival in the range of 76.1-29.5% (p = 0.00033) and 60.9-15.9% (p = 0.0011), respectively, with median survival of 15 months, 5 months, or 3 months for patients with none, one, or more than one adverse prognostic factor(s), respectively. CONCLUSIONS: This study confirms the prognostic value of the RTOG RPA classification, lymphopenia, and tumor HR status, which can be used to form a prognostic score for patients with BM from breast carcinoma.
