Abstract
Abstract
BACKGROUND: PARP, an essential nuclear enzyme, is involved in the recognition of DNA damage and facilitation of DNA base-excision repair (BER). PARP inhibition sensitizes tumor cells to cytotoxic agents which induce DNA damage, including C. Metronomic dosing of C may optimize potential for synergy with PARP inhibitors, and also inhibits angiogenesis (Kerbel et al, Nat Rev Cancer, 4:423-36, 2004) and may enhance anti-tumor immunity (Ghiringhelli et al. Cancer Immunol Immunother 56:641–648, 2007) V is an oral small molecule inhibitor of PARP which potentiates the antineoplastic activity of DNA damaging agents such as C in MX-1 breast xenograft model (Donawho et al Clin Cancer Res 13:2728-37, 2007). We performed a phase I trial of metronomic dose oral C plus V in patients with MBC.
METHODS: The primary objective was to determine the safety and identify the recommended phase II dose (RPTD) of the combination of low-dose oral C once daily in combination with V (100, 200, 300 mg) administered BID for 21 days using a standard 3+3 design. Eligibility included HER2/neu negative MBC, ECOG PS 0-1, and at least 1 prior chemotherapy regimen for MBC. Dose limiting toxicity (DLT) was defined as any Grade 3 non-hematological toxicity or Grade 4 thrombocytopenia/neutropenia occurring during cycle 1. After the RPTD of V was shown to be 200 mg BID with C 50 mg daily, the trial was amended to increase the C dose to 75, 100 and then 125 mg daily until hematologic toxicity was dose-limiting.
RESULTS: 31 patients were enrolled, 19 treated with 50 mg of C and 12 treated at higher doses (75-125 mg), with V doses ranging from 50 mg-300 mg BID (see table);5 patients with not evaluable due to rapid disease progression (N=2), non-compliance (N=2), or tumor pain that was not a DLT (N=1). Median age was 52 years (28-72 years), 14 (45 %) had triple negative disease, all had at least 1 prior chemotherapy regimen for metastasis (median 2, range 1-8), and, 7 had germline BRCA mutations, (3 BRCA1 and 4 BRCA2). When combined with 50 mg C daily, RPTD of V was 200 mg PO BID, with nausea being DLT at 300 mg BID. DLT was not observed in any of the 9 additional patients. The median number of cycles given was 3 (range 1-14). Clinical benefit (response or stable disease for at least 24 weeks) occurred in 3/7 (43%), 1/3 (33%) and 1/16(6%) for BRCA mutated, BRCA negative and BRCA unknown, respectively. Median progression-free survival was 4.3 months (1.2-10.9 months) for BRCA mutated patients and 2 months (0.7-10 months) for non-mutated.
CONCLUSIONS: The combination of oral continuous dosing of V (200 mg PO BID) with metronomic C (50, 75, 100 and 125 mg daily) is well tolerated and shows antitumor activity in patients with BRCA mutation associated MBC. The RPTD is C 125 mg daily plus V 200 mg BID, although further escalation of the C dose may be feasible since DLT was not seen at this dose level.

Abstract
Abstract
Resistance to standard taxane-based chemotherapy is common in triple-negative breast cancer (TNBC). Mutations and gene amplifications in the MAPK pathway that upregulate MAPK signaling are present in many TNBC tumors. Upregulation of the MAPK signaling pathway can result in degradation of the pro-apoptotic protein BIM and upregulation of anti-apoptotic proteins, including BCL-2, BCL-XL, and MCL-1, thus promoting cell survival and desensitizing tumor cells to the pro-apoptotic effects of taxane chemotherapy. Updated data on clinical safety and efficacy are presented along with biomarker data evaluating the effects of treatment on induction of apoptosis.The COLET study (ClinicalTrials.gov ID, NCT02322814; EudraCT number, 2014-002230-32) consisted of a safety run-in (n∼12) followed by a blinded 1:1 randomized expansion stage (n∼90) to C + P or placebo (PBO) + P. The safety stage is complete and the randomized stage is enrolling pts. Two additional cohorts investigating the effect of adding atezolizumab will be recruiting and are out of scope of this submission. Pts in cohort I were treated with P 80 mg/m2 on days 1, 8, and 15 and C/PBO 60 mg/day on days 3–23 of each 28-day cycle until disease progression or unacceptable toxicity. Gene expression and apoptotic index were measured by RNA-Seq and TUNEL staining, respectively, to assess the biologic activity of C + P.Sixteen women (median age, 55.5 years) were enrolled in the safety run-in stage. At data snapshot (April 22, 2016), all 16 pts had received ≥1 dose of study treatment. Median time on treatment was 116 days (range, 7-336) for C and 84 days (range, 0-351) for P. Fifteen (94%) pts had ≥1 adverse event (AE); 5 (31%) pts had grade 1/2 AEs and 10 (63%) pts had grade 3 AEs (Table). No pts experienced grade 4–5 AEs. Among the 16 safety run-in patients, responses to date include partial response (PR; n = 8 [50.0%]), stable disease (SD, n = 4 [25.0%]), and progressive disease (n = 2 [12.5%]), as well as 2 pts with no post-baseline tumor assessment. Six pts maintained a PR at ∼20 weeks and three maintained a PR at ≥40 weeks. To date, matched pre- and on-treatment biopsies were evaluable for 2 pts, 1 with a PR and 1 with SD. In the patient who attained a PR, increased expression of pro-apoptosis genes, including BIM, was observed; but this was not seen in the patient experiencing SD. The PR patient also had an increase in apoptotic index. Updated biomarker data will be reported.This is the first study to evaluate C + P in TNBC. The safety profile of C + P is consistent with that of known safety profiles. Efficacy and safety will be further evaluated in the ongoing randomized stage.

Abstract
Purpose Squamous cell carcinoma of the anal canal (SCCAC) is characterized by high locoregional failure (LRF) rates after sphincter-preserving definitive chemoradiation (CRT) and is typically associated with anogenital human papilloma virus infection. Because cetuximab enhances the effect of radiation therapy in human papilloma virus-associated oropharyngeal squamous cell carcinoma, we hypothesized that adding cetuximab to CRT would reduce LRF in SCCAC. Methods Sixty-one patients with stage I to III SCCAC received CRT including cisplatin, fluorouracil, and radiation therapy to the primary tumor and regional lymph nodes (45 to 54 Gy) plus eight once-weekly doses of concurrent cetuximab. The study was designed to detect at least a 50% reduction in 3-year LRF rate (one-sided α, 0.10; power 90%), assuming a 35% LRF rate from historical data. Results Poor risk features included stage III disease in 64% and male sex in 20%. The 3-year LRF rate was 23% (95% CI, 13% to 36%; one-sided P = .03) by binomial proportional estimate using the prespecified end point and 21% (95% CI, 7% to 26%) by Kaplan-Meier estimate in a post hoc analysis using methods consistent with historical data. Three-year rates were 68% (95% CI, 55% to 79%) for progression-free survival and 83% (95% CI, 71% to 91%) for overall survival. Grade 4 toxicity occurred in 32%, and 5% had treatment-associated deaths. Conclusion Although the addition of cetuximab to chemoradiation for SCCAC was associated with lower LRF rates than historical data with CRT alone, toxicity was substantial, and LRF still occurs in approximately 20%, indicating the continued need for more effective and less toxic therapies.

Abstract
Metastasis is the primary cause of death in early-stage breast cancer. We evaluated the association between a metastasis biomarker, which we call "Tumor Microenviroment of Metastasis" (TMEM), and risk of recurrence. TMEM are microanatomic structures where invasive tumor cells are in direct contact with endothelial cells and macrophages, and which serve as intravasation sites for tumor cells into the circulation. We evaluated primary tumors from 600 patients with Stage I-III breast cancer treated with adjuvant chemotherapy in trial E2197 (NCT00003519), plus endocrine therapy for hormone receptor (HR)+ disease. TMEM were identified and enumerated using an analytically validated, fully automated digital pathology/image analysis method (MetaSite Breast™), hereafter referred to as MetaSite Score (MS). The objectives were to determine the association between MS and distant relapse free interval (DRFI) and relapse free interval (RFI). MS was not associated with tumor size or nodal status, and correlated poorly with Oncotype DX Recurrence Score (r = 0.29) in 297 patients with HR+/HER2- disease. Proportional hazards models revealed a significant positive association between continuous MS and DRFI (p = 0.001) and RFI (p = 0.00006) in HR+/HER2- disease in years 0-5, and by MS tertiles for DRFI (p = 0.04) and RFI (p = 0.01), but not after year 5 or in triple negative or HER2+ disease. Multivariate models in HR+/HER- disease including continuous MS, clinical covariates, and categorical Recurrence Score (<18, 18-30, > 30) showed MS is an independent predictor for 5-year RFI (p = 0.05). MetaSite Score provides prognostic information for early recurrence complementary to clinicopathologic features and Recurrence Score.

Abstract
BACKGROUND Compared to non-Hispanic whites, African-American women tend to be diagnosed with breast cancer at an earlier age, to have less favorable tumor characteristics, and to have poorer outcomes from breast cancer. The extent to which differences in clinical characteristics account for the black/white disparity in breast cancer mortality is unclear. The purpose of this investigation was to examine the association of clinical, demographic, and treatment variables with total mortality and breast cancer recurrence by race/ethnicity in a cohort of women diagnosed with invasive breast cancer. METHODS To this end, we used data on 3890 invasive breast cancer cases diagnosed at a single medical center. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for the association of tumor characteristics and treatment variables with mortality and recurrence. RESULTS Compared to white women, black women with breast cancer presented with tumors that had worse prognostic factors, particularly higher stage, lower frequency of hormone-receptor positive tumors, and higher frequency of comorbidities. Hispanics also generally had less favorable prognostic factors compared to non-Hispanic whites. Among estrogen receptor-positive cases, blacks had roughly a two-fold increased risk of recurrence compared to non-Hispanic whites. However, ethnicity/race was not associated with total mortality. Tumor stage, tumor size, and Charlson comorbidity index were positively associated with mortality, and mammography and chemotherapy and hormone therapy were inversely associated with mortality. CONCLUSION In spite of poorer prognostic factors among blacks compared whites, race/ethnicity was not associated with total mortality in our study.

Abstract
PURPOSE Anthracycline-induced congestive heart failure (CHF) is a rare but serious toxicity associated with this commonly employed anticancer therapy. The ability to predict which patients might be at increased risk prior to exposure would be valuable to optimally counsel risk-to-benefit ratio for each patient. Herein, we present a genome-wide approach for biomarker discovery with two validation cohorts to predict CHF from adult patients planning to receive anthracycline. EXPERIMENTAL DESIGN We performed a genome-wide association study in 3,431 patients from the randomized phase III adjuvant breast cancer trial E5103 to identify single nucleotide polymorphism (SNP) genotypes associated with an increased risk of anthracycline-induced CHF. We further attempted candidate validation in two independent phase III adjuvant trials, E1199 and BEATRICE. RESULTS When evaluating for cardiologist-adjudicated CHF, 11 SNPs had a P value <10-5, of which nine independent chromosomal regions were associated with increased risk. Validation of the top two SNPs in E1199 revealed one SNP rs28714259 that demonstrated a borderline increased CHF risk (P = 0.04, OR = 1.9). rs28714259 was subsequently tested in BEATRICE and was significantly associated with a decreased left ventricular ejection fraction (P = 0.018, OR = 4.2). CONCLUSIONS rs28714259 represents a validated SNP that is associated with anthracycline-induced CHF in three independent, phase III adjuvant breast cancer clinical trials.

Abstract
The proteasome inhibitor bortezomib enhances the effect of the selective estrogen receptor (ER) downregulator (SERD) fulvestrant by causing accumulation of cytoplasmic ER aggregates in preclinical models. The purpose of this trial was to determine whether bortezomib enhanced the effectiveness of fulvestrant. One hundred eighteen postmenopausal women with ER-positive metastatic breast cancer resistant to aromatase inhibitors (AIs) were randomized to fulvestrant alone (Arm A-500 mg intramuscular (i.m.) day -14, 1, 15 in cycle 1, and day 1 of additional cycles) or in combination with bortezomib (Arm B-1.6 mg/m2 intravenous (i.v.) on days 1, 8, 15 of each cycle). The study was powered to show an improvement in median progression-free survival (PFS) from 5.4 to 9.0 months and compare PFS rates at 6 and 12 months (α=0.10, β=0.10). Patients with progression on fulvestrant could cross over to the combination (arm C). Although there was no difference in median PFS (2.7 months in both arms), the hazard ratio for PFS in Arm B versus Arm A (referent) was 0.73 (95% confidence interval (CI)=0.49, 1.09, P=0.06, 1-sided log-rank test, significant at the prespecified 1-sided 0.10 α level). At 12 months, the PFS proportion in Arm A and Arm B was 13.6% and 28.1% (P=0.03, 1-sided χ2-test; 95% CI for difference (14.5%)=-0.06, 29.1%). Of 27 patients on arm A who crossed over to the combination (arm C), 5 (18%) were progression-free for at least 24 weeks. Bortezomib likely enhances the effectiveness of fulvestrant in AI-resistant, ER-positive metastatic breast cancer by reducing acquired resistance, supporting additional evaluation of proteasome inhibitors in combination with SERDs.

Abstract
PURPOSE Taxane-induced peripheral neuropathy (TIPN) is one of the most important survivorship issues for cancer patients. African Americans (AA) have previously been shown to have an increased risk for this toxicity. Germline predictive biomarkers were evaluated to help identify a priori which patients might be at extraordinarily high risk for this toxicity. EXPERIMENTAL DESIGN Whole exome sequencing was performed using germline DNA from 213 AA patients who received a standard dose and schedule of paclitaxel in the adjuvant, randomized phase III breast cancer trial, E5103. Cases were defined as those with either grade 3-4 (n=64) or grade 2-4 (n=151) TIPN and were compared to controls (n=62) that were not reported to have experienced TIPN. We retained for analysis rare variants with a minor allele frequency <3% and which were predicted to be deleterious by protein prediction programs. A gene-based, case-control analysis using SKAT was performed to identify genes that harbored an imbalance of deleterious variants associated with increased risk of TIPN. RESULTS Five genes had a p-value < 10-4 for grade 3-4 TIPN analysis and three genes had a p-value < 10-4 for the grade 2-4 TIPN analysis. For the grade 3-4 TIPN analysis, SET binding factor 2 (SBF2) was significantly associated with TIPN (p-value=4.35 x10-6). Five variants were predicted to be deleterious in SBF2. Inherited mutations in SBF2 have previously been associated with autosomal recessive, Type 4B2 Charcot-Marie-Tooth (CMT) disease. CONCLUSION Rare variants in SBF2, a CMT gene, predict an increased risk of TIPN in AA patients receiving paclitaxel.

Three-year rates by Kaplan-Meier estimate were 72% (95% CI, 56% to 84%) for progression-free survival and 79% (95% CI, 63% to 89%) for overall survival. Grade 4 toxicity occurred in 26%, and 4% had treatment-associated deaths. Conclusion HIV-associated SCCAC is potentially curable with definitive CRT. Although addition of cetuximab may result in less LRF, the 20% recurrence and 26% grade 4 toxicity rates indicate the continued need for more-effective and less-toxic therapies.

Abstract
Abstract
Chemotherapy induces influx of bone marrow-derived progenitors such as mesenchymal stem cells, endothelial progenitors and proangiogenic monocytes into the primary tumor to promote angiogenesis. Thus it is feared that chemotherapy may potentiate tumor cell invasion and metastasis. Here, we show that paclitaxel delays tumor growth in several mammary carcinoma mouse and human breast cancer models, yet it significantly increases the density of microanatomical sites called “tumor microenvironment of metastasis” (TMEM) that are responsible for tumor cell intravasation and dissemination of breast cancer. The TMEM site consists of a Mena-overexpressing cancer cell in direct contact with a Tie2hi/VEGFhi macrophage and an underlying endothelial cell. Mice treated with paclitaxel have significantly more circulating tumor cells (CTCs) and metastatic foci when compared to vehicle-treated animals indicating that the chemotherapy-induced TMEM are active in assisting tumor cell intravasation. Moreover, syngeneic transplantation of Dendra2+/PyMT tumors into FVB recipients showed significantly higher incidence of Dendra2+ cells in the lung, following paclitaxel administration. In parallel experiments, paclitaxel induced the influx of macrophages and intravasation of cancer cells as observed using intravital imaging of MMTV-PyMT-Dendra2/Cfms-CFP mice, in which blood vessels were visualized with Quantum dots. Furthermore, paclitaxel treatment in experimental mice caused a significant increase in the expression of Mena at the gene and protein levels. PCR assays for total Mena (PanMena) or specific Mena isoforms (MenaINV, Mena11a) revealed that this increase was particularly attributed to the invasive Mena isoforms [i.e. MenaINV and MenaCalc (Menacalc = PanMena - Mena11a)]. These pre-clinical data are supported by the findings from a cohort of 10 breast cancer patients who received neoadjuvant dose-dense paclitaxel followed by doxorubicin/ cyclophosphamide. Of these tumors, 7/10 patients had more than 2-fold increase in TMEM density following neoadjuvant chemotherapy regimen. Moreover, chemotherapy produced an acute increase of up to 150-fold in MenaINV expression in 3/7 and up to 5.5-fold in MenaCalc in 3/4 patients who underwent serial fine needle aspiration (FNA) biopsy before and after 1-2 doses of either neoadjuvant paclitaxel or doxorubicin-cyclophosphamide. This is provocative because an increase in either MenaCalc score or TMEM density are independently associated with increased risk of distant recurrence in breast cancer patients. In conclusion, our data indicate that paclitaxel treatment induces intravasation-mediated dissemination of breast cancer cells in rodents and in certain clinical scenarios in humans by promoting increases in MenaCalc expression and TMEM intravasation sites.

Abstract
Central nervous system (CNS) involvement is reportedly more common in acquired immunodeficiency syndrome (AIDS)-related lymphomas (ARL). We describe factors and outcomes associated with CNS involvement at baseline (CNS(B) ) and relapse (CNS(R) ) in 886 patients with newly diagnosed ARL. Of 886 patients, 800 received either intrathecal (IT) therapy for CNS(B) or IT prophylaxis. CNS(B) was found in 13%. CNS(B) was not associated with reduced overall survival (OS). There was no difference in the prevalence of CNS(B) between the pre-combination antiretroviral therapy (cART) and cART eras. 5·3% of patients experienced CNS(R) at a median of 4·2 months after diagnosis (12% if CNS(B) ; 4% if not). Median OS after CNS(R) was 1·6 months. On multivariate analysis, only CNS(B) [hazard ratio (HR) 3·68, P = 0·005] and complete response to initial therapy (HR 0·14, P < 0·0001) were significantly associated with CNS(R) . When restricted to patients without CNS(B) , IT CNS prophylaxis with 3 vs. 1 agent did not significantly impact the risk of CNS(R) . Despite IT CNS prophylaxis, 5% of patients experienced CNS(R) . Our data confirms that CNS(R) in ARL occurs early and has a poor outcome. Complete response to initial therapy was associated with a reduced frequency of CNS(R) . Although CNS(B) conferred an increased risk for CNS(R) , it did not impact OS.

Abstract
BACKGROUND Prior studies with the use of a prospective-retrospective design including archival tumor samples have shown that gene-expression assays provide clinically useful prognostic information. However, a prospectively conducted study in a uniformly treated population provides the highest level of evidence supporting the clinical validity and usefulness of a biomarker. METHODS We performed a prospective trial involving women with hormone-receptor-positive, human epidermal growth factor receptor type 2 (HER2)-negative, axillary node-negative breast cancer with tumors of 1.1 to 5.0 cm in the greatest dimension (or 0.6 to 1.0 cm in the greatest dimension and intermediate or high tumor grade) who met established guidelines for the consideration of adjuvant chemotherapy on the basis of clinicopathologic features. A reverse-transcriptase-polymerase-chain-reaction assay of 21 genes was performed on the paraffin-embedded tumor tissue, and the results were used to calculate a score indicating the risk of breast-cancer recurrence; patients were assigned to receive endocrine therapy without chemotherapy if they had a recurrence score of 0 to 10, indicating a very low risk of recurrence (on a scale of 0 to 100, with higher scores indicating a greater risk of recurrence). RESULTS Of the 10,253 eligible women enrolled, 1626 women (15.9%) who had a recurrence score of 0 to 10 were assigned to receive endocrine therapy alone without chemotherapy. At 5 years, in this patient population, the rate of invasive disease-free survival was 93.8% (95% confidence interval [CI], 92.4 to 94.9), the rate of freedom from recurrence of breast cancer at a distant site was 99.3% (95% CI, 98.7 to 99.6), the rate of freedom from recurrence of breast cancer at a distant or local-regional site was 98.7% (95% CI, 97.9 to 99.2), and the rate of overall survival was 98.0% (95% CI, 97.1 to 98.6). CONCLUSIONS Among patients with hormone-receptor-positive, HER2-negative, axillary node-negative breast cancer who met established guidelines for the recommendation of adjuvant chemotherapy on the basis of clinicopathologic features, those with tumors that had a favorable gene-expression profile had very low rates of recurrence at 5 years with endocrine therapy alone.

Abstract
Breast cancer is a heterogeneous disease associated with variable clinical outcomes despite standard local therapy for the primary tumor and systemic adjuvant therapy to prevent distant recurrence. Management decisions are typically made using classical prognostic and predictive clinicopathologic factors, and more recently gene expression profiling assays are commonly used in practice. Recent advances in genomic sequencing-often referred to collectively as next-generation sequencing (NGS)-have facilitated more in-depth evaluation of the cancer genome than could be afforded by the initial generation of gene expression studies, including DNA single nucleotide variants, small insertions and deletions, structural alterations, and copy number alterations (CNAs). In addition, this information has been integrated with other molecular profiling methods of processes that affect gene transcription (e.g., epigenetic, microRNA) and protein expression-the ultimate readout of the genetic code. Although NGS has provided new insights on the classification of breast cancer and identified potential predictive biomarkers and novel targets, there are formidable logistical and scientific obstacles that must be addressed before the promise of this technology is fully realized.

Abstract
PURPOSE The aims of this study were to determine whether pretreatment plasma levels of cytokines and immune activation-associated molecules changed following treatment for AIDS-NHL with rituximab plus infusional EPOCH, and to determine whether pretreatment levels of these molecules were associated with response to treatment and/or survival. EXPERIMENTAL DESIGN We quantified plasma levels of B-cell activation-associated molecules (sCD27, sCD30, and sCD23) and cytokines (IL6, IL10, and CXCL13) before and after the initiation of treatment in persons with AIDS-NHL (n = 69) in the AIDS Malignancies Consortium (AMC) 034 study, which evaluated treatment of AIDS-NHL with EPOCH chemotherapy and rituximab. RESULTS Treatment resulted in decreased plasma levels of some of these molecules (CXCL13, sCD27, and sCD30), with decreased levels persisting for one year following the completion of treatment. Lower levels of CXCL13 before treatment were associated with complete responses following lymphoma therapy. Elevated levels of IL6 pretreatment were associated with decreased overall survival, whereas higher IL10 levels were associated with shorter progression-free survival (PFS), in multivariate analyses. Furthermore, patients with CXCL13 or IL6 levels higher than the median levels for the NHL group, as well as those who had detectable IL10, had lower overall survival and PFS, in Kaplan-Meier analyses. CONCLUSIONS These results indicate that CXCL13, IL6, and IL10 have significant potential as prognostic biomarkers for AIDS-NHL.

Abstract
PURPOSE To determine the 12-year risk of developing an ipsilateral breast event (IBE) for women with ductal carcinoma in situ (DCIS) of the breast treated with surgical excision (lumpectomy) without radiation. PATIENTS AND METHODS A prospective clinical trial was performed for women with DCIS who were selected for low-risk clinical and pathologic characteristics. Patients were enrolled onto one of two study cohorts (not randomly assigned): cohort 1: low- or intermediate-grade DCIS, tumor size 2.5 cm or smaller (n = 561); or cohort 2: high-grade DCIS, tumor size 1 cm or smaller (n = 104). Protocol specifications included excision of the DCIS tumor with a minimum negative margin width of at least 3 mm. Tamoxifen (not randomly assigned) was given to 30% of the patients. An IBE was defined as local recurrence of DCIS or invasive carcinoma in the treated breast. Median follow-up time was 12.3 years. RESULTS There were 99 IBEs, of which 51 (52%) were invasive. The IBE and invasive IBE rates increased over time in both cohorts. The 12-year rates of developing an IBE were 14.4% for cohort 1 and 24.6% for cohort 2 (P = .003). The 12-year rates of developing an invasive IBE were 7.5% and 13.4%, respectively (P = .08). On multivariable analysis, study cohort and tumor size were both significantly associated with developing an IBE (P = .009 and P = .03, respectively). CONCLUSION For patients with DCIS selected for favorable clinical and pathologic characteristics and treated with excision without radiation, the risks of developing an IBE and an invasive IBE increased through 12 years of follow-up, without plateau. These data help inform the treatment decision-making process for patients and their physicians.
