    Notes: Abstract Surgical specimens from 60 Japanese women with breast cancer were studied histochemically to detect estrogen receptors (ER). Forty-six were analyzed in a double blind study designed to compare the histochemical method using fluorescent estradiol conjugate for detection of ER (FITC method) with findings in case of the currently employed dextran coated charcoal (DCC method) techniques. The ER test was positive in 39 (65 percent) of the 60 cases studied by FITC method. Of the 46 cases analysed in a double blind study, 41 (89.8 percent) showed the same results. Of the 5 with inconsistent test results, 2 showed positive DCC and negative FITC, and 3, negative DCC and positive FITC. According to the histologic type, the FITC method demonstrated a low positive ER response rate in scirrhous cases (57 per cent), whereas the positive rate was 67 percent among papillotubular-type cases and 65 percent among medullary tubullar-type cases. In relation to menstrual status, the positive rates were 68 percent and 64 percent among premenopausal and postmenopausal women, respectively. However, in relation to tumor size, no difference was noted in the positive response rate by either method. Therefore, both the DCC and FITC methods are clinically useful to determine the indications for hormone therapy.

    Notes: Abstract A study on surgical biopsy for treatment of breast cancer was done by sending out questionnaires to membership institutions of the Japan Mammary Cancer Society. The problems related to diagnostic biopsy of the breast mainly concern the following two points; the first is the methodology, incisional or excisional, the second, whether delay between biopsy and radical mastectomy influences survival. The prognostic features in patients with excisional biopsy were significantly superior. As for the lapse of time between biopsy and radical mastectomy, 14 days were considered safe, and under conditions such as T2 or n0, this maximum was 7 days.

    Notes: Abstract Left suprarenal-inferior mesenteric venous shunt (Inokuchi) was prescribed for 80 patients with recurrent breast cancer and the efficacy of hormone coditioned cancer chemotherapy was assessed. The patients were separated into 3 groups according to the historical regimen of combined chemotherapy: Group I; surgical hormone therapy alone, Group II; surgery plus short term chemotherapy, and Group III; surgery plus long term chemotherapy. The 5 year survival rate of the responsive patients to the surgical hormone therapy was as high as 84.6 per cent in Group III, as compared to that of Groups I and II, 41.7 per cent and 16.7, respectively. Survival was not prolonged in non-responsive patients, regardless of the group. These findings indicate that surgical hormone therapy combined with postoperative long term cancer chemotherapy is a valid and effective method for treating recurrence of breast cancer.

    Notes: Abstract Microscopic cancer is extremely rare even among “occult breast cancers”. We treated a 70 year old woman with complaints of serosanguineous nipple discharge which yielded cytologically Class V cancer cells. Microdochectomy was performed and intraductal carcinoma was verified histologically in serially cut sections. Following a simple mastectomy, she has been well with no evidence of recurrence or metastasis, at this time.

    Notes: ERBB2 , INT2, and MYC genes, in 131 patients with breast carcinoma, 49 of whom had lymph node involvement, but none of whom had distant metastases. Among the several chromosome arms tested, LOH at 17q was correlated with lymph node metastasis. Amplification of the ERBB2, MYC, and INT2 genes was found more frequently in tumors from patients with lymph node metastases than in tumors from those without lymph node metastases. Univariate analysis demonstrated that LOH at 17q and INT2 amplification were factors influencing disease-free survival (DFS). A multivariate analysis was performed on 89 tumors that were able to be evaluated for both LOH at 17q and INT2 amplification, and the results showed that patients who had tumors with these genetic changes were more likely to have a poor prognosis. The findings of this study suggest that investigating genetic changes, in addition to conventional clinicopathologic factors, may contribute to defining groups of breast cancer patients with differences in prognosis.

    Notes: Abstract Background:The association between BRCA1 germ-linemutations and breast cancer prognosis is controversial. A historical cohortstudy was designed to determine the prognosis for women with axillary lymphnode negative hereditary breast cancer. Patients and methods:We tested pathology blocks from 118Ashkenazi Jewish women with axillary lymph node negative breast cancer for thepresence of the two common BRCA1 founder mutations, 185delAG and5382insC. Patients were followed up for a median of 76 months. SomaticTP53mutations were screened for by immunohistochemistry, and directsequencing was performed in the BRCA1-positive tumours. Results:Sixteen breast cancer blocks (13.6%) carried aBRCA1 mutation. Young age of onset, high nuclear grade, negativeestrogen receptor status and over-expression of p53 were highly associatedwith BRCA1-positive status (P-values all 〈0.01).BRCA1 mutation carriers had a higher mortality than non-carriers(five-year overall survival, 50% and 89.6%, respectively,P = 0.0001). Young age of onset, estrogen receptor negative status,nuclear grade 3, and over-expression of p53 also predicted a poor outcome. Coxmultivariate analyses showed that only germ-line BRCA1 mutationstatus was an independent prognostic factor for overall survival (P= 0.01). Among nuclear grade 3 tumours, the BRCA1 mutation carrierstatus was a significant prognostic factor of death (risk ratio 5.8,95% confidence interval: 1.5–22, P = 0.009). Sequencingof BRCA1-related breast cancers revealed one TP53missensemutation not previously reported in breast cancer. Conclusions:Using a historical cohort approach, we haveidentified BRCA1 mutation status as an independent prognostic factorfor node negative breast cancer among the Ashkenazi Jewish women. Thosemanaging women carrying a BRCA1 mutation may need take these findingsinto consideration. Additionally, our preliminary results, taken together withthe work of others suggest a different carcinogenic pathway inBRCA1-related breast cancer, compared to non-hereditary cases.

    Notes: Abstract Background:The selection of therapies for breast cancer is todaybased on prognostic features (chemotherapy, radiotherapy), hormone receptorstatus (hormonal therapy) and HER-2 status (trastuzumab therapy). HER-2,p53and BCL-2are tumour-related proteins that have thepotential to further improve individualisation of patient management, bypredicting response to chemotherapy, hormonal therapy and radiotherapy. Materials and methods:This paper reviews the rationale for theuse of these proteins as predictive factors, as well as the publishedliterature addressing the use of each one to predict response to hormonaltherapy, chemotherapy and radiotherapy. Results:HER-2, p53and BCL-2remaininadequately assessed as predictive factors in breast cancer. HER-2 evaluationis required for the selection of patients for trastuzumab (Herceptin®)therapy, as trials of this therapy have been limited to HER-2 overexpressors.HER-2 overexpression may be predictive of resistance to hormonal therapy.Anthracyclines are effective therapy for breast cancer regardless of HER-2status, but patients whose tumours overexpress HER-2 appear to receive thegreatest relative benefit from this therapy. Studies of HER-2 as a predictorof response to CMF and to radiotherapy are inconclusive at this time. No datayet exist to support the use of p53or BCL-2as predictivefactors in the therapy of breast cancer. Conclusions:At this point in time, there is inadequate evidenceto support the use of HER-2, p53or BCL-2to guide theselection of hormonal therapy, chemotherapy or radiotherapy for breast cancer.

    Notes: Abstract Background:GI147211 is a water-soluble synthetic analogue ofcamptothecin showing promising in vivoand in vitroantitumor activity and an acceptable toxicity profile. Patients and methods:Between April 1995 and November 1996, 67eligible patients with pretreated breast cancer (25 patients) andchemo-naïve colorectal (19 patients) and non-small-cell lung cancer (23patients) were entered into three multicentric, non-randomized phase IItrials. Treatment schedule consisted of intravenous GI147211 administered ata dose of 1.2 mg/m2/day for five consecutive days every threeweeks. Results:Hematological toxicity was common with grade 3–4neutropenia in 54% of patients and neutropenic fever together or notassociated with infection in 14.5% of patients. Grade 3–4thrombocytopenia and grade 2–4 anemia were observed in 20% andin 68% of patients, respectively. Non-hematological toxicity wasgenerally mild to moderate and consisted mainly of gastrointestinal toxicity,asthenia and alopecia. A dose-escalation to 1.5 mg/m2/d wasfeasible in 17 (25%) patients. The antitumor activity of GI147211 wasmoderate in breast cancer patients (3 partial responses (PRs), response rate(RR) 13%) and minimal in non-small cell lung cancer patients (2 PRs,RR 9%). No objective responses were obtained in colorectal patients. Conclusions:GI147211, at the dose and schedule employed in thisstudy, showed an acceptable safety profile but a modest antitumor activity inthe examined tumor types.

    Notes: Abstract Using microfabrication technology, we have developed a new experimental apparatus and technique which allow isolation of individual cells and which facilitate the study of kinetic volume changes and membrane permeability. The key component of the apparatus is a microdiffusion chamber which was constructed using silicon microfabrication technology and standard photolithography. The central unit of the chamber is a 1 μ m thick silicon nitride membrane with a center hole on the order of 2–3 μ m in diameter. The device is novel in its analysis of a single cell, instead of the traditional array of cells, and its avoidance of the damage artifacts and computational difficulties which are inherent in other, commonly used methods of cellular analysis. The device is used in conjunction with a predictive computer model which simulates the response of the entire membrane or a portion of the membrane to various permeant and impermeant concentrations. This study introduces the apparatus and the model, and illustrates the effectiveness of the new procedure by determining several membrane permeability coefficients for HBL-100 (healthy human breast line). The empirical data and theoretical data were combined to yield a water permability (L p) of 1.1 ± 0.5μ m/(min-atm) (mean ± 1 standard deviation) (N= 5) during the uncoupled transport of water at 22 ±C. In the presence of 6 M glycerol, the water permeability (L p), permeability coefficient (P S), and the reflection coefficient (σS) were determined to be 2.0 ± 0.63 μ m/(min-atm), 2.7E-5 ± 6.1E-6 cm-sec-1, and 0.76 ± 0.5 (N = 6). No previous values of these coefficients could be found for HBL-100 cells.
