Metastasising ability connotes one of the most important life-threatening properties of malignant neoplasms. Recent studies indicate that CD44 proteins, multifunctional cell adhesion molecules which contribute to "homing" of lymphocytes to lymph nodes as well as cell-cell and cell-matrix interactions, are potential markers of tumour progression. However, whether CD44 expression by human tumours contribute to increased metastatic risk remains controversial. In an attempt to clarify its role in breast cancer, we have investigated the correlation between CD44 expression by breast carcinoma and the presence of axillary lymph node metastases. CD44 expression was detected using a standard immunoperoxidase method on formalin-fixed, paraffin-embedded, primary infiltrating ductal breast carcinoma tissues taken from 60 female patients who underwent mastectomy with axillary node clearance. Tumours were graded according to the modified Bloom and Richardson criteria. 62% of patients had histologically-proven lymph node metastasis. 40% of primary cancers exhibited cytoplasmic membrane immunopositivity for CD44. 46% of primary tumours which have metastasied to axillary lymph nodes were CD44 positive whereas 30% of tumours which have not metastasised expressed CD44. CD44 positivity was expressed by 20% of grade 1, 31% grade 2 and 58% grade 3 tumours. Our results suggest that CD44 may have a role in the progression of breast cancer and emphasise the need to investigate its interaction with other mechanisms of cancer advancement.

We reviewed the cases of breast cancer that had not been detected by physical examination (PE), ultrasound (US) and mammography (MMG). Of 90 cases that were diagnosed as breast cancer definitely on pathological assay, 13 cases had gone unnoticed by PE, seven by US, and 15 by MMG. Thus, the detection rate worked out at 85.6%, 92.2% and 83.3%, respectively. When the diagnoses wee made by any combination of one with another, the detection rate for joint PE/US, PE/MMG and US/MMG came to95.6%, 97.8% and 98.9%, indicating that the combined use of US and MMG was most efficient.Tumors that had been undetected by PE and MMG were significantly smaller in size than those that had been detected, but this was not the case for tumors that had gone unnoticed by US. Therefore, we considered that oversight during US examination is more likely due to difficulty making diagnostic differentiation between cancer and fatty tissue or cyst, etc. than tumor size. We found that those cases which had gotten pass PE had a significantly lower histological grade malignancy and a lower grade of invasiveness than the other cases of breast cancer, even though the former tended to show lymphatic metastasis frequently. Furthermore, all of these metastatic breast cancers had a smaller diameter ranging from 0.8cm to 0.9cm. This suggested hat we cannot afford to let them pass because they are non-palpable. At present, the Japanese Ministry of Health, Labor and Welfare are recommending the breast cancer mass-screening by use of PE in combinationwith MMG. However, because MMG is not always omnipotent and lets many breast cancer cases pass, we should conduct the mass screening with US and MMG but without PE.

Recently the evaluation of health-related quality of life (QOL) in cancer patients has become important in carrying out a treatment strategy. During a period between June and August 2004, we studied the QOL in 16 breast cancer patients with or without chemotherapy. The regimens of chemotherapy were EC (n=6), AT (n=1) and CMF (n=1). We made the Functional Assessment of Cancer Therapy Scale-General (FACT-G) in all patients. The patients treated without chemotherapy were superior to those with chemotherapy with respect to physical and emotional well-being (p<0.05). There were no differences in social well-being and relationship to families between the two groups. The patients treated without chemotherapy made significantly higher scores in the basic activities of daily living than those with chemotherapy (p<0.05). Compared with patients receiving chemotherapy, patients treated without chemotherapy had better quality of life (p<0.05). We concluded that it was important for us to assist in decision making about treatment and supportive care needs.

The crude methanol extracts of Gelsemium elegans leaves were assessed for their cytotoxic activity using the microculture 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cellular viability. This study utilized two different types of human cancer cell lines, CaOV-3 (human ovarian cancer cells) and MDA-MB-231 (human estrogen receptor negative breast cancer cells), allowing for comparison of toxicity of G. elegans against these two cancer cells lines. Our results showed that the methanol extract of G. elegans exhibited high cytotoxicity against the human ovarian cancer cell line CaOV-3 with an IC50 value of 5microg/ml after 96 h incubation. However, G. elegans displayed discernibly less toxicity against the MDA-MB-231 cells with an IC50 value 40microg/ml after 96 h incubation and this effect was dose- and time-dependent, up to 72h and 20-30 microg/ml. In conclusion, our results demonstrated that G. elegans is potently cytotoxic against the human ovarian cancer cell line CaOV-3 and to a lesser extend towards the human breast carcinoma cancer MDA-MB-231 cells, suggesting that the extract is selective towards CaOV-3 cells and may have a chemotherapeutic role for ovarian cancer treatment in the future.

The estrogen hormone receptor (ER) content of human breast cancer has assumed an important role as a predictor of hormone therapy response and as a prognostic indicator. The conventional technique is the dextran-coated charcoal (DCC) method or a ligand-binding assay (LBA) based on the measurement of radiolabeled steroids in cytosolic extracts of tissue homogenate. The recent introduction of monoclonal antibodies with high specificity for human ERs has allowed the application of immunocytochemical assays (ICA) in human cancer tissue. An extension of the ICA technique to cytologic specimens is also widely used. Our aim was to evaluate the reliability of ER-ICAs on fine needle aspirates(FNA) from breast cancer patients by comparing it with ER-ICAs and ER-LBAs performed on surgically removed tissues. During a recent 6-month period, ER-ICAs and ER-LBAs were performed in 83 cases. Among these 83 cases, only the 40 cases for which the ER-ICA and the ER-LBA were performed simultaneously ere included in this study. As positive cutoff values, we assumed 10 fmol/mg protein for the ER-LBAs and a semiquantitative score of 4 for the ER-ICAs. The results were as follows : 1) The ER positive rate was 55% (22/40) for ICAs and 47.5% (19/40) for LBAs. The concordance rate between the ER of ICAs and that of LBAs was 82.5% (33/40). 2) The Pearson correlation coefficient between ER-ICAs of fine needle aspirates and that of surgically removed tissue was good (r=0.94, p<0.005) 3) The Spearman correlation coefficient between ER-ICAs of fine needle aspirates and ER-LBAs of surgically removed tissue was good (r=0.57, p=0.0001) In conclusion, ER determination by using the fine needle aspirate is a reliable method in palpable breast cancer. FNA-ER may be a useful method when it is difficult to take sufficient breast cancer tissue, i.e., in cases of diffusely recurrent cancer, liver metastasis, malignant pleural effusion, etc.

Lung cancer, breast cancer and lymphoma are the common oncologic causes of malignant pleural effusion, comprising more than the half of the causes. However, an endocrinologic carcinoma associated malignant effusion is very rare. Recently, we encountered a case of papillary thyroid carcinoma causing malignant effusion. An 83-year-old female patient presented with dyspnea due to massive pleural effusion in her left side. The pleural biopsy, pleural fluid cytology and breast needle aspiration biopsy results were consistent with a metastatic papillary thyroid carcinoma. Thyroid ultrasonography showed two thyroid masses, but the patient refused a thyroid biopsy. This case highlights the need for considering the possibility of papillary thyroid carcinoma when the cause of malignant pleural effusion cannot be found because one of the rare clinical manifestations of a papillary thyroid carcinoma can be dyspnea due to malignant effusion.
