Background: Male breast cancer (MBC) is a rare disease representing less than 1% of breast cancers. In the absence of a screening program, such as for females, the diagnostic workup is critical for early detection of MBC.

Objectives: To summarize our institutional experience in the workup of male patients referred for breast imaging, emphasizing the clinical, imaging, and histopathological characteristics of the MBC cohort.

Methods: All male patients who underwent breast imaging between 2011 and 2016 in our institution were retrospectively reviewed. Clinical, radiological, and histopathological data were collected and statistically evaluated. All images were reviewed using the American College of Radiology Breast Imaging Reporting and Data System.

Results: 178 male patients (average age 61 years, median age 64), underwent breast imaging in our institution. The most common indication for referral was palpable mass (49%) followed by gynecomastia (16%). Imaging included mostly mammography or ultrasound. Biopsies were performed on 56 patients, 38 (68%) were benign and 18 (32%) were malignant. In all, 13 patients had primary breast cancer and 5 had metastatic disease to the breast. Palpable mass at presentation was strongly associated with malignancy (P = 0.007).

Conclusion: Mammography and ultrasound remain the leading modalities in breast imaging among males for diagnostic workup of palpable mass, with gynecomastia being the predominant diagnosis. However, presentation with palpable mass was also associated with malignancy. Despite a notable MBC rate in our cohort, the likelihood of cancer is low in young patients and in cases of gynecomastia.

Background: Automated breast volumetric sonography (ABVS) is a new technology with various possible applications.

Objectives: To compare ABVS and breast magnetic resonance imaging (MRI) in the surveillance of women with BRCA1/2 gene mutation carriers.

Methods: We conducted a prospective study in Jewish female BRCA1/2 mutation carriers who underwent breast MRI and ABVS. The results of both exams performed 6 months apart or less, and relevant clinical data, were reviewed. The BIRADS results were divided into three subgroups according to subsequent expected management: BIRADS 1-2 (normal study), BIRADS 3 (probably benign finding), and BIRADS 4 and 5 (suspicious findings). BIRADS 0 and 6 scores were excluded from the study. Distribution of ABVS and MRI BIRADS scores were compared using McNemar's test, and concordance was calculated using the Cohen kappa test.

Results: Overall, 68 women, 40 BRCA1 and 28 BRCA2 mutation carriers, age range 26–69 (mean 44.55 ± 12.1 years), underwent 79 paired ABVS and MRI examinations. McNemar's test calculations showed no significant difference between MRI and ABVS BIRADS score distribution. Cohen’s kappa test resulted in k = 0.158, an agreement that can be described as only "slight agreement" between both modalities. Of 14 discordant cases there was one cancer, revealed by MRI and not by ABVS performed 6 months prior to MRI.

Conclusions: ABVS showed slight agreement with MRI in BRCA1/2 mutation carriers. These preliminary results on a small group of healthy high risk patients suggest that the diagnostic abilities of ABVS are inferior to MRI. Further studies encompassing larger groups are needed.

 

Breast magnetic resonance imaging (MRI) has an important role in the detection and diagnosis of breast cancer. Suspicious findings on MRI are further evaluated with ultrasound. This case series illustrates the use of automated breast volumetric ultrasound (ABVS) as a tool for second-look ultrasound (SLUS) following MRI. Seven women underwent breast MRI with findings necessitating SLUS. ABVS was used for second look and all MRI lesions were detected. Four cancers, one fibroadenoma and two benign lesions, were diagnosed. This case series shows that ABVS can be used as a tool for SLUS following MRI and in some cases is superior to hand-held ultrasound.

Background: Diabetes mellitus is a multi-organ disorder affecting many types of connective tissues, including bone and cartilage. Certain skeletal changes are more prevalent in diabetic patients than in non-diabetic individuals. A possible association of diabetes mellitus and lumbar spinal stenosis has been raised.

Objectives: To compare the prevalence of diabetes mellitus in patients with spinal stenosis, degenerative disk disease or osteoporotic vertebral fractures.

Methods: A cross-sectional analysis was performed of 395 consecutive patients diagnosed with spinal stenosis, degenerative disk disease or osteoporotic vertebral fractures. All the patients were examined by one senior author in the outpatient orthopedic clinic of a large general hospital between June 2004 and January 2006 and diagnosed as having either lumbar spinal stenosis (n=225), degenerative disk disease (n=124) or osteoporotic vertebral fractures (n=46).

Results: The prevalence of diabetes mellitus in the three groups (spinal stenosis, osteoporotic fracture, degenerative disk disease) was 28%, 6.5% and 12.1%, respectively, revealing a significantly higher prevalence in the spinal stenosis group compared with the others (P = 0.001). The higher prevalence of diabetes in the stenotic patients was unrelated to the presence of degenerative spondylolisthesis.

Conclusions: There is an association between diabetes and lumbar spinal stenosis. Diabetes mellitus may be a predisposing factor for the development of lumbar spinal stenosis.

Background: The imaging parameters that mandate further diagnostic workup in focal asymmetric breast densities are not clearly defined.

Objectives: To identify indications for further workup in FABD[1] by comparing mammographic and ultrasonographic findings with the pathology results of women with FABD.

Methods: Ninety-four women (97 FABD) were referred for core needle biopsy after incidental discovery of FABD on routine mammograms (n=83) or on diagnostic mammograms performed for palpable masses (n=11). Clinical data included patient’s age, use of hormone replacement therapy, family history of breast cancer, and the presence of a palpable mass. Mammograms and sonograms were evaluated for lesion size and location, associated calcifications, architectural distortion, and change from previous examinations when available. Two patient groups emerged according to the pathological findings and the data were compared.

Results: The average age, size and location of the lesions in the malignant (n=5) and benign (n=92) groups were similar. There was a significant difference (P < 0.05) for the presence of a clinically palpable mass (60% vs. 9%, respectively), a cluster of calcifications (60% vs. 12%), associated architectural distortion (exclusively in the malignant group) and a solid mass on sonography (50% vs. 9%). The malignant group had a higher rate of family history of breast cancer and HRT[2] use.

Conclusions: FABD usually present a benign etiology and can safely be managed by follow‑up. The presence of an architectural distortion, a cluster of malignant‑appearing or indeterminate calcifications, a sonographic mass with features of possible malignancy, or a clinically palpable mass mandates tissue diagnosis.

Background: The current methods for pre‑ and post‑chemotherapy examination of the extent of disease in the breast and lymph nodes do not provide sufficiently accurate information and, not infrequently, the surgeon has to re‑operate.

Objectives: To correlate the findings between three methods of examination (physical examination, ultrasonography, mammography), all performed by the same oncologic and radiologic team, in patients with locally advanced breast cancer or a tumor/breast tissue ratio that precludes breast-conserving surgery.

Methods: Forty patients (median age 48 years, range 24–73) with locally advanced breast cancer or with a tumor/breast ratio that precluded breast‑conserving surgery were evaluated by the same medical team and received neoadjuvant chemotherapy. Surgery was performed in all, and the pathologic specimen was correlated with the results of the other examinations.

Results: In the pre‑chemotherapy evaluation, the imaging findings of the breast correlated with the physical findings in 78% of the patients and with the axilla examination in 66.7%. In the post‑chemotherapy analysis, imaging agreed with the physical findings of the breast in 62.2% and in 76.3% of the axilla. Sonography best detected occult breast disease and axillary lymph nodes but correlated with pathology in only 58% of the patients in diagnosing breast tumor and in 65.8% in diagnosing axillary lymph nodes. Mammography correlated with breast and lymph node pathology in half the patients.

Conclusions: None of the classical methods of post‑neoadjuvant chemotherapy evaluations could adequately delineate the actual extent of the disease in the breast and axillary lymph nodes. More exacting techniques of imaging combined with the classical methods are required.

Background: Metastatic melanoma is an aggressive and highly malignant cancer. The 5 year survival rate of patients with metastatic disease is less than 5% with a median survival of only 6–10 months. Drugs like dacarbazin (DTIC) as a single agent or in combination with other chemotherapy agents have a response rate of 15–30%, but the duration of response is usually short with no impact on survival. Interleukin-2-based immunotherapy has shown more promising results. The National Institutes of Health recently reported that lymphodepleting chemotherapy, followed by an adoptive transfer of large numbers of anti-tumor specific tumor-infiltrating lymphocytes, resulted in an objective regression in 51% of patients.

Objectives: To introduce the TIL[1] technology to advanced metastatic melanoma patients in Israel.

Methods: We generated TIL cultures from tumor tissue, choosing those with specific activity against melanoma and expanding them to large numbers.

Results: TIL cultures from nine patients were established and examined for their specific activity against the patients' autologous tumor cells. Twelve TIL cultures derived from 5 different patients showed the desired anti-tumor activity, making those 5 patients potential candidates for the therapy.

Conclusions: Pre-clinical studies of the TIL technology in a clinical laboratory set-up were performed successfully and this modality is ready for treating metastatic melanoma patients at the Sheba Medical Center's Ella Institute.

Intravascular lymphoma is a rare sub-type of extranodal diffuse large B cell lymphoma characterized by the presence of lymphoma cells only in the lumina of small vessels, particulary capillaries

Fanconi anemia is a rare autosomal recessive disorder characterized clinically by congenital abnormalities, progressive bone marrow failure, and a predisposition to malignancy. FA cells are sensitive to DNA cross-linking agents. Complementation analysis of FA cells using somatic cell fusion has facilitated the identification of eight complementation groups, suggesting that FA is a genetically heterogeneous disorder. Six genes (FANCA, FANCC, FANCD2, FANCE, FANGF, FANCG) have been cloned so far. The majority of affected patients belong to FA group A. Of the 32 unrelated Israeli patients with FA that we studied, 6 carried the FANCC mutations and 15 the FANCA mutations. Among the Jewish patients, ethnic-related mutations were common. Recent cumulative evidence suggests that the FA proteins are repair proteins. FANCC, FANCA and FANCG bind and interact in a protein complex found in the cytoplasm and nucleus of normal cells. FANCD2 exists in two isoforms; the long active form, FANCD2-L, is absent from FA cells of all complementation groups. FANCD2 co-localized with BRCA1 in unclear foci, probably as part of a large genomic surveillance complex. Studies using FANCA and FANCC knockout mice suggest that bone marrow precursors express interferon-g hypersensitivity and show progressive apoptosis. The definition of the molecular basis of FA in many affected families now enables prenatal diagnosis.
