Endoscopic and Histologic Findings of Intraductal Lesions Presenting with Nipple Discharge

Abstract:   To improve the utility of mammary ductoscopy, we investigated the correlation between endoscopic findings and histologic findings using intraductal biopsy specimens. Seventy-one intraductal biopsy specimens obtained from 63 patients between October 2001 and March 2004 were analyzed retrospectively. All specimens were obtained from monotonous intraductal lesions immediately after observation by mammary ductoscopy and were composed of a pure histologic subtype. With regard to endoscopic findings, color was classified as yellow, red, white, or colorless, and morphology was classified as spherical, lobular, mulberry, or amorphous. The histologic subtype was classified as papillotubular, papillary, degenerated, papillary cancer, solid-type ductal carcinoma in situ (DCIS), or cribriform cancer. The relationship between histologic diagnosis, color, and morphology was investigated. Intraductal biopsy specimens included 25 specimens of carcinoma and 46 specimens of papilloma. There was no significant correlation between color and diagnosis. Fourteen of 25 carcinoma specimens were amorphous, and amorphous morphology was significantly suggestive of malignancy (p < 0.001). Further, cribriform cancer was associated with amorphous morphology and yellow color. Morphology may be a useful endoscopically delineated parameter for differentiating intraductal lesions.

Persistence of Mammary Artery Branches and Blood Supply to the Left Anterior Descending Artery

Background. Partial harvesting of the left internal mammary artery (LIMA) is a widespread technique used during minimally invasive coronary operations performed through a left anterior small thoracotomy. The influence of persisting LIMA branches was investigated to evaluate their effect on the blood flow of the left anterior descending artery.

Methods. Thirty patients, 15 with totally (group A) and 15 with partially (group B) harvested LIMAs, were evaluated. All the patients underwent postoperative angiography, during which a flow map of the LIMA was performed. The average peak velocity and the diastolic-to-systolic peak velocity ratio were recorded. The LIMA graft flow pattern was recorded in the proximal and distal thirds of the artery. Intramammary adenosine (12 to 14 μg) was injected and the average peak velocities before and after injection were calculated.

Results. The average peak velocity was similar in both groups in the proximal and distal thirds of the LIMA (25 ± 7 and 26 ± 5 cm/sec, respectively, in group A versus 27 ± 5 and 25 ± 5 cm/sec, respectively in group B; p = NS). The diastolic-to-systolic peak velocity ratio was similar proximally (0.78 ± 0.3 in group A versus 0.69 ± 0.3 cm/s in group B; p = NS), but not distally (1.72 ± 0.1 in group A versus 0.97 ± 0.3 in group B; p < 0.0005). The LIMA graft flow reserve was similar both proximally and distally (2.6 ± 0.6 and 2.5 ± 0.3 cm/s, respectively, in group A versus 2.6 ± 0.5 and 2.6 ± 0.3 cm/s, respectively, in group B; p = NS).

Conclusions. The persistence of LIMA branches does not influence the blood flow of the left anterior descending artery after acute adenosine-induced myocardial hyperemia. If a left anterior small thoracotomy is used in left anterior descending artery direct revascularization, complete LIMA harvesting is not mandatory and depends on the personal preference of the surgeon.

Inhibition by indomethacin of spontaneous mammary tumorigenesis in SHN mice

This experiment was designed to examine the effects of indomethacin, a potent prostaglandin synthesis inhibitor, on spontaneous mammary tumors in mice. The growth of established mammary tumors and the appearance of new tumors in multiparous SHN mice were significantly suppressed by the subcutaneous implantation of pellets of indomethacin diluted to 1/12 with cholesterol. Furthermore, the same treatment inhibited normal and preneoplastic mammary gland growth in virgin SHN mice. The pattern of estrous cycles, ovarian structure, and plasma prolactin levels were not affected significantly by the treatment. All results have demonstrated that indomethacin inhibits mammary tumorigenesis of mice primarily by route(s) other than the endocrine system under the present experimental conditions. Indomethacin would be the first agent that appears to inhibit the growth of spontaneous mammary tumors of palpable size in mice.     

Growth inhibition of estrogen independent MXT mouse mammary carcinomas in mice treated with an agonist or antagonist of LH-RH,an analog of somatostatin,or a combination

Summary Female BDF₁ mice inoculated with MXT (3.2) estrogen independent mouse mammary carcinoma were treated for three weeks with microcapsules of the luteinizing hormone-releasing hormone (LH-RH) agonist [D-Trp⁶]LH-RH, the antagonist SB-75, the somatostatin analog RC-160, or combinations. The lack of estrogen dependence of the tumor was proved by bilateral surgical ovariectomy, which had no effect. In two experiments, treatment with 25µg/day doses of each analog alone resulted in a significant inhibition of tumor growth as shown by a 40–53% inhibition of tumor volumes, 38–43% decrease in tumor weights, and histological signs of tumor regression. However, the combination of SB-75 or [D-Trp⁶]LH-RH with somatostatin analog RC-160 caused greater reduction of tumor volume (68 and 61%) or tumor weights (59 and 56%), than single analogs, and histologically the occurrence of apoptosis and decrease in AgNOR numbers was more pronounced in the groups receiving combination therapy. Specific binding sites for [D-Trp⁶]LH-RH, EGF, and IGF-I were demonstrated in the tumor membranes. The binding capacity of LH-RH receptors was decreased by treatment with the analogs, the greatest down-regulation being caused by combination therapy. A significant decrease in EGF binding capacity was observed after treatment with the LH-RH analogs, alone or especially in combination with somatostatin analog RC-160. The combination of these analogs also caused a reduction in IGF-I receptors. The finding that LH-RH agonists and antagonists and somatostatin analogs inhibit the growth of estrogen independent mammary tumors, and that combinations are more effective than single analogs, might be of practical importance in human breast cancer therapy.
