Objective Individuals with amnestic mild cognitive impairment (MCI) have few empirically based treatment options for combating their memory loss. This study sought to examine the efficacy of a calendar/notebook rehabilitation intervention, the memory support system (MSS), for individuals with amnestic MCI. Methods Forty individuals with single domain amnestic MCI and their program partners were randomized to receive the MSS, either with training or without (controls). Measures of adherence, activities of daily living, and emotional impact were completed at the first and last intervention sessions and again at 8 weeks and 6 months post intervention. Results Training in use of a notebook/calendar system significantly improved adherence over those who received the calendars but no training. Functional ability and memory self‐efficacy significantly improved for those who received MSS training. Change in functional ability remained significantly better in the intervention group than in the control group out to 8‐week follow‐up. Care partners in the intervention group demonstrated improved mood by 8‐week and 6‐month follow‐ups, whereas control care partners reported worse caregiver burden by 6‐month follow‐up. Conclusions Memory support system training resulted in improvement in activities of daily living and sense of memory self‐efficacy for individuals with MCI. Although activities of daily living benefits were maintained out to 8 weeks post intervention, future inclusion of booster sessions may help extend the therapeutic effect out even further. Improved mood of care partners of trained individuals and worsening sense of caregiver burden over time for partners of untrained individuals further support the efficacy of the MSS for MCI.

The development of subspecialty tumor groups for uncommon malignancies represents an effective approach to building experience, increasing patient volumes and referrals, and fostering development of increased therapeutic options and clinical trials for patients afflicted with otherwise historically neglected cancers.

Abstract Background: Genome-wide association studies (GWAS) identified variants at 19p13.1 and ZNF365 (10q21.2) as risk factors for breast cancer among BRCA1 and BRCA2 mutation carriers, respectively. We explored associations with ovarian cancer and with breast cancer by tumor histopathology for these variants in mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). Methods: Genotyping data for 12,599 BRCA1 and 7,132 BRCA2 mutation carriers from 40 studies were combined. Results: We confirmed associations between rs8170 at 19p13.1 and breast cancer risk for BRCA1 mutation carriers [HR, 1.17; 95% confidence interval (CI), 1.07–1.27; P = 7.42 × 10−4] and between rs16917302 at ZNF365 (HR, 0.84; 95% CI, 0.73–0.97; P = 0.017) but not rs311499 at 20q13.3 (HR, 1.11; 95% CI, 0.94–1.31; P = 0.22) and breast cancer risk for BRCA2 mutation carriers. Analyses based on tumor histopathology showed that 19p13 variants were predominantly associated with estrogen receptor (ER)-negative breast cancer for both BRCA1 and BRCA2 mutation carriers, whereas rs16917302 at ZNF365 was mainly associated with ER-positive breast cancer for both BRCA1 and BRCA2 mutation carriers. We also found for the first time that rs67397200 at 19p13.1 was associated with an increased risk of ovarian cancer for BRCA1 (HR, 1.16; 95% CI, 1.05–1.29; P = 3.8 × 10−4) and BRCA2 mutation carriers (HR, 1.30; 95% CI, 1.10–1.52; P = 1.8 × 10−3). Conclusions: 19p13.1 and ZNF365 are susceptibility loci for ovarian cancer and ER subtypes of breast cancer among BRCA1 and BRCA2 mutation carriers. Impact: These findings can lead to an improved understanding of tumor development and may prove useful for breast and ovarian cancer risk prediction for BRCA1 and BRCA2 mutation carriers.

AbstractBackgroundIndications and survival benefit for adrenalectomy (ADX) in the setting of metastasis are not clearly defined. We aimed to determine which patients with primary malignancies may benefit from ADX performed for metastasis. Mayo Clinic institutional outcomes in patients with metastatic disease to the adrenal(s) treated by adrenalectomy were compared to stage‐matched historical controls from the Surveillance Epidemiology and End Results (SEER) database.MethodsA retrospective review (1992–2010) was conducted to identify patients treated with ADX for metastatic cancer at Mayo Clinic, Rochester. Associations of clinical, surgical, and pathologic features with overall survival (OS) were evaluated using Cox proportional regression models. OS for those treated with ADX was compared with that for SEER database stage‐matched patients who underwent primary resection without resection of distant disease using log‐rank tests.ResultsA total of 166 patients underwent ADX for metastatic primaries involving the kidney 60, lung 24, sarcoma 19, colon 15, pancreas 13, and other‐35. Patients with sarcoma and kidney, lung, and pancreatic tumors who underwent ADX had better OS at 1, 2, and 3 years than did the SEER‐matched controls. Respectively, the rates were for sarcoma (100, 93, 86% vs. 57, 36, 30%), kidney (86, 80, 72% vs. 55, 37, 27%), lung (91, 69, 52% vs. 52, 34, 25%), and pancreas (79, 56, 45% vs. 33, 20, 12%). Univariate analysis identified primary diagnosis <2 years before ADX, other distant site, pancreatic primary, palliative operation, and persistent disease as risk factors for death.ConclusionsAn aggressive surgical approach results in improved OS in patients with metastatic disease arising from soft tissues, kidney, lung, and pancreas. Other tumors may benefit, but larger study cohorts are needed for a meaningful comparison.

Abstract Identification of HER2 as an important cellular marker in the biology and treatment of breast cancer has highlighted the importance of reliable testing methodology. Controversy exists regarding type of test, reliability, definition of positivity, and which test may best predict for patient (pt) efficacy to anti-HER2 therapies. Purpose: To determine the concordance between HER2 results by 3 central laboratories, impact of round-robin adjudication of discordant cases, and heterogeneity in HER2 results using specimens from 3 adjuvant trials where HER2 testing was performed by local and central laboratories for enrollment. Methods: We performed a blinded round-robin exchange of randomly sampled, HER2-normal (IHC-& FISH-) and HER2-positive breast tumors among 3 central laboratories (NCCTG, BCIRG and NSABP) for confirmatory HER2 testing. The 3 laboratories performed immunohistochemistry (IHC) for HER2 using the HercepTest kit (Dako, Carpenteria, CA) and fluorescence in situ hybridization (FISH) for HER2 using the PathVysion HER2 DNA probe kit/HER2/CEN17 probe mixture (Abbott Molecular, Des Plaines, IL) on 389 tumor specimens obtained from N9831/BCIRG006 (37 IHC+/FISH+, 33 IHC+/FISH-, 36 IHC-/FISH+, 62 IHC-& FISH-) and BCIRG005 (96 IHC-& FISH-); 123 cases had ≥2 blocks examined from the same pt. HER2 positivity was defined according to FDA-approved guidelines used in the clinical trials (IHC+: 3+ complete membrane staining in &gt;10% cells; FISH+: HER2/CEN17 ratio ≥2.0). The HER2 status (IHC: 3+ vs 0-2+; FISH: amplified vs not) for each block was independently determined at each site; discordant IHC and FISH cases were adjudicated at a face-to-face meeting. Results: Independent reads were concordant across pathologists in IHC status in 351/381 (92%) cases and in FISH status in 343/373 (92%) cases. Upon adjudication, a consensus was reached on 16 and 18 of the discordant IHC and FISH cases, respectively. Among 96 BCIRG005 cases, IHC-and FISH-were confirmed in the primary block in all 96 cases. Among 59 evaluable N9831 HER2-normal cases, IHC-and FISH-were confirmed in the primary block in 57 (97%) cases (but another block tested HER2+ for 4 cases). Among 102 N9831/BCIRG006 HER2+ cases, HER2 positivity was confirmed in the primary block in 73 (72%) cases. Among 118 cases with IHC results for &gt; 1 block, the adjudicated IHC result agreed across blocks in 106 (90%) cases. Among 113 cases with FISH results for &gt;1 block, the adjudicated FISH result agreed in 107 (95%) cases. Among 53 N9831 HER2-normal cases adjudicated as IHC-& FISH-(although they all had a previous local HER2+ test), there was significant improvement in disease-free survival associated with trastuzumab given concurrently with paclitaxel after doxorubicin and cyclophosphamide compared to chemotherapy alone (HR=0.31, 95% CI 0.11-0.91; A 23 pts, 10 events; C 30 pts, 5 events). Conclusions: Excellent agreement (96%) was observed among the pathologists at adjudication, suggesting that standardized methods improve assay proficiency. HER2 heterogeneity across blocks was observed more at the protein than at the gene level. In the small subset of N9831 pts adjudicated as HER2-normal trastuzumab benefit was observed.
