RESUMEN
BACKGROUND: There is no consensus regarding the management of benign papillary breast lesions diagnosed on image-guided core needle biopsy (IGCNB). METHODS: This is a retrospective review of 407 patients within Kaiser Permanente Northern California diagnosed between 2012 and 2013. The study focused on patients presenting with a mass lesion and who were diagnosed with a benign papillary breast lesion (BPBL) on IGCNB. Patients who did not have surgical excision of the IGCNB papilloma were followed for at least 2 years. RESULTS: A total of 327 patients (80%) underwent surgical excision, 61 patients (15%) had follow-up imaging, and 19 patients (5%) had no surgery or imaging. Overall among women with surgical excision, 9.5% had a high-risk lesion, 3.4% had in situ cancer, and 2.4% had invasive cancer. An upgrade to an in situ cancer or invasive cancer was more common among women with a lesion greater than 1 cm, a palpable breast mass, age > 50 years, or if the lesion was > 5 cm from the nipple. No cancers were diagnosed in 61 women followed by imaging surveillance. CONCLUSIONS: This is the largest, single-cohort study of benign papillary mass lesions diagnosed on IGCNB. On surgical excision, the overall rate of upgrade to in situ cancer and invasive cancer was low, and almost all cancers diagnosed had favorable features. Because no cancers were found in women who were followed by imaging, we conclude that outcomes for BPBL diagnosed on IGCNB are favorable whether surgical excision or surveillance is the treatment choice.

OBJECTIVES: To assess the safety and efficacy of atezolizumab and docetaxel in patients with and without a history of asymptomatic, treated brain metastases in the phase III OAK trial. MATERIALS AND METHODS: Patients received 1200 mg atezolizumab or 75 mg/m2 docetaxel every 3 weeks until unacceptable toxicity, disease progression, or loss of clinical atezolizumab benefit. Patients with asymptomatic, treated supratentorial metastases were eligible. Patients had brain scans before enrollment; follow-up brain scans and treatment were required when clinically indicated. RESULTS: Approximately 14% of patients in each arm had a history of asymptomatic, treated brain metastases (61/425 in the atezolizumab arm and 62/425 in the docetaxel arm). Fewer treatment-related adverse events (AEs), serious AEs, and treatment-related neurologic AEs were reported with atezolizumab than with docetaxel, regardless of history of asymptomatic, treated brain metastases. In patients with a history of asymptomatic, treated brain metastases, median overall survival (OS) was longer with atezolizumab than with docetaxel (16.0 vs 11.9 months; hazard ratio = 0.74; 95% CI: 0.49-1.13). Median OS was also longer with atezolizumab in patients without a history of asymptomatic, treated brain metastases (13.2 vs 9.3 months; hazard ratio = 0.74; 95% CI: 0.63-0.88). Landmark analyses showed that patients with a history of asymptomatic, treated brain metastases had a lower probability of developing new symptomatic brain lesions with atezolizumab vs docetaxel at 6-24 months. Patients without a history had a lower probability with atezolizumab at 18-24+ months. CONCLUSION: Atezolizumab had an acceptable neurologic safety profile, showed a trend toward an OS benefit, and led to a prolonged time to radiographic identification of new symptomatic brain lesions compared with docetaxel in patients who had a history of asymptomatic, treated brain metastases. Clinicaltrials.gov registration number: NCT02008227.

OBJECTIVE: This study aimed to test the feasibility of a 12-month weight loss intervention using telephone-based counseling plus community-situated physical activity (PA) in female breast cancer (BC) and colorectal cancer (CRC) survivors. METHODS: This multisite cooperative group study enrolled sedentary, female, postmenopausal BC and CRC survivors with BMI ≥ 25 kg/m2 to receive 12-month fitness center memberships and telephone counseling encouraging 150 min/wk of PA and a 500-kcal/ddecrease in energy intake. Feasibility criteria included accrual, adherence, and retention. Target weight loss was ≥ 5%. RESULTS: Among 25 BC survivors, median baseline BMI was 37.2 (range: 27.7-54.6), accrual occurred in 10 months, 60% and 28% met diet and exercise goals, 80% provided 12-month measures, and average weight loss was 7.6% (95% CI: -3.9%, 19.2%). Among 23 CRC survivors, median BMI was 31.8 (range: 26.4-48.7), accrual occurred in 24 months, 61% and 17% met diet and exercise goals, 87% provided measures, and average weight loss was 2.5% (95% CI: -8.2%, 13.3%). CONCLUSIONS: It is feasible to recruit and retain BC survivors in a cooperative group diet and PA weight loss trial. BC survivors achieved clinically meaningful weight loss but did not meet a priori adherence goals. In CRC survivors, recruitment was more difficult, and the intervention was less effective.

PURPOSE: The regimens of weekly irinotecan with platinum have been used for treatment of metastatic small-cell lung cancer (SCLC). We conducted a multi-institution phase II trial to evaluate a novel 21-day schedule of irinotecan and carboplatin in patients with relapsed or extensive SCLC. PATIENTS AND METHODS: Eighty patients were enrolled with the following characteristics: 39 male patients, 41 female patients; median age, 65 years; and Zubrod performance status, 0 to 1 in 85% and 2 in 15% of patients. Dosing schemas were based on the maximum-tolerated dose derived in a previous phase I study. Chemotherapy-naive patients with extensive SCLC were treated with irinotecan 200 mg/m(2) and carboplatin area under the curve (AUC) of 5 (arm A). Patients, who had previously been treated with chemotherapy and had relapsed disease received irinotecan 150 mg/m(2) and carboplatin AUC of 5 (arm B). In each study arm, the treatment was given every 21 days for up to six cycles. RESULTS: The most common grade 3 to 4 toxicities included neutropenia (54%), thrombocytopenia (22%), anemia (13%), diarrhea (22%), and nausea/emesis (11%) in both study arms. There were three treatment-related deaths owing to neutropenic sepsis. Among 72 assessable patients, response rates of 65% and 50% were observed, respectively, for arm A and arm B. The median survival for both study arms was identical at 10 months (95% CI, 6 to 14 months). A response rate of 65% was observed in the intracranial disease of 14 patients with known brain metastases. CONCLUSION: This 21-day regimen of irinotecan and carboplatin seems promising for the treatment of relapsed SCLC.

PURPOSE: Brain metastasis occurs commonly in patients with small-cell lung cancer (SCLC). Herein, we report the efficacy of irinotecan and carboplatin in the treatment of brain metastases from SCLC. In addition, we review the existing data on chemotherapy for brain metastases in SCLC. PATIENTS AND METHODS: Eighty patients with metastatic or relapsed SCLC were enrolled in a phase II trial of irinotecan and carboplatin. Patients naive to chemotherapy were treated with irinotecan 200 mg/m2 and carboplatin AUC of 5, and patients previously treated with chemotherapy received irinotecan 150 mg/m2 and carboplatin AUC of 5, every 21 days for 6 cycles. RESULTS: Among the 80 patients, 15 (19%) presented with brain metastases. An analysis of 14 assessable patients with brain metastases revealed an overall response rate of 65% after 2 cycles of chemotherapy and a median survival of 6 months (range, 1-24 months). Upon review of the literature, 8 studies were identified as having > 10 patients who received chemotherapy for brain metastases from SCLC. Based on these studies, the response rate of brain metastases from SCLC to a variety of chemotherapy and median survival of patients ranged from 22% to 85% and 3 months to 9 months, respectively. CONCLUSION: Chemotherapy, including the regimen of irinotecan and carboplatin, is an effective treatment for SCLC brain metastases.

PURPOSE: Erlotinib is a potent reversible HER1/epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor with single-agent activity in patients with non-small-cell lung cancer (NSCLC). Erlotinib was combined with chemotherapy to determine if it could improve the outcome of patients with NSCLC. PATIENTS AND METHODS: TRIBUTE randomly assigned patients with good performance status and previously untreated advanced (stage IIIB/IV) NSCLC to erlotinib 150 mg/d or placebo combined with up to six cycles of carboplatin and paclitaxel, followed by maintenance monotherapy with erlotinib. Random assignment was stratified by stage, weight loss in the previous 6 months, measurable disease, and treatment center. The primary end point was overall survival (OS). Secondary end points included time to progression (TTP), objective response (OR), and duration of response. RESULTS: There were 1,059 assessable patients (526 erlotinib; 533 placebo). Median survival for patients treated with erlotinib was 10.6 v 10.5 months for placebo (hazard ratio, 0.99; 95% CI, 0.86 to 1.16; P = .95). There was no difference in OR or median TTP. Patients who reported never smoking (72 erlotinib; 44 placebo) experienced improved OS in the erlotinib arm (22.5 v 10.1 months for placebo), though no other prespecified factors showed an advantage in OS with erlotinib. Erlotinib and placebo arms were equivalent in adverse events (except rash and diarrhea). CONCLUSION: Erlotinib with concurrent carboplatin and paclitaxel did not confer a survival advantage over carboplatin and paclitaxel alone in patients with previously untreated advanced NSCLC. Never smokers treated with erlotinib and chemotherapy seemed to experience an improvement in survival and will undergo further investigation in future randomized trials.
