    Notes: Abstract:   Advances in the therapeutic agents used for neoadjuvant chemotherapy (NAC) have recently achieved higher response rates and induced a greater number of pathologic complete responses (pCR) than ever before. The aim of this study is the diagnosis of pCR after NAC by diagnostic imaging of clinical complete response (cCR) patients. This study included 35 breast cancer patients who demonstrated cCR after receiving NAC with a combination of anthracycline and taxane from May 1998 to August 2003. Surgical treatment included breast-conserving therapy followed by radiotherapy or mastectomy. The identity of post-NAC lesions as either a complete response (CR) or partial response (PR) were made by mammography, ultrasonography, and contrast-enhanced computed tomography (CT). Among the 35 patients, 11 achieved pCR, including the disappearance of both invasive and intraductal components. Of the patients achieving pCR, eight were defined as CR and three were determined to be PR by CT. There was a significant relationship between the pCR and the determination of CR by CT. The determination of CR by ultrasonography was indicative of the disappearance of pathologic invasive components. While mammography appeared to reflect the observed histologic results, we did not observe any statistical differences. A subset of cases exhibited discrepancies between the imaging and pathologic results, likely due to the replacement of destroyed tumor cells by fibrosis and granulomatous tissue. The evaluation of CR by CT was significantly indicative of pCR. The positive predictive value, however, was not large enough to avoid surgical treatment. Further studies will be needed to establish a diagnosis of pCR.

    Notes: Abstract  This study was performed to identify any relationship between age and cisplatin (CDDP) pharmacokinetics in lung cancer patients. CDDP was given at a dose of 80 mg/m2 by 1-h intravenous infusion to 23 lung cancer patients. All patients had normal renal, hepatic, and bone marrow functions. We measured ultrafilterable platinum (U-Pt) and total plasma platinum (T-Pt) using atomic absorption spectrometry. There was significant correlation between the age of the patients and U-Pt pharmacokinetic parameters such as the area under the plasma concentration versus time curve (AUC), total clearance (Cl), and peak plasma concentration (Cmax) as well as the AUC of T-Pt (P〈0.05). We performed univariate regression analysis to examine the influence of factors aside from age on the AUC of U-Pt and T-Pt. Creatinine and GPT levels were significantly related to the AUC of U-Pt, and creatinine clearance and creatinine concentrations were significantly related to the AUC of T-Pt. Therefore, stepwise multiple-regression models for the AUC of U-Pt and T-Pt were developed to assess an age effect. Age was consistently an independent and significant predictor of the AUC of U-Pt and T-Pt.

    Notes: Abstract Purpose: KRN8602 (3′-deamino-3′-morpholino-13-deoxo-10-hydroxycarminomycin hydrochloride, MX2 · HCl) is a newly developed anthracycline that has been found to be effective against multidrug-resistant tumor cells in vitro and in vivo. In order to clinically confirm these promising preclinical observations, we performed a phase II trial of KRN8602 in patients with anthracycline-resistant metastatic breast cancer. Methods: Of 41 patients registered with metastatic breast cancer, 37 were eligible and were given at least two cycles of KRN8602 15 mg/m2 per day at 3–4 week intervals by intravenous bolus injection on days 1, 2, and 3. Results: Of the 37 patients, 6 (16.2%, with a 95% confidence interval of 4.3–28.1%) had a partial response (PR). No complete responses (CRs) were observed. The difference between response rates according to prior history of anthracycline administration was not significant. Myelosuppression was moderately severe, with grade 3 or 4 leukopenia occurring in 65%. Severe nausea/vomiting was observed in 44% of the patients. Conclusions: The results indicate that KRN8602 has modest activity in refractory metastatic breast cancer and is associated with relatively severe toxicity. Furthermore, the preclinical finding that KRN8602 overcomes anthracycline resistance was not reliably reproduced in this clinical phase II trial.

    Notes: Abstract Background: The bedside wellness system (BSW) is effective for decreasing stress and improving mental well-being and should help relieve the side effects and mental disorders of patients during cancer chemotherapy. Methods: The study was a randomized clinical trial. After giving informed consent, patients were randomly assigned to the BSW intervention or control groups. The patients were given the Hospital Anxiety and Depression Scale (HADS) test before the trial to evaluate their emotional baseline. The Cancer Fatigue Scale, which was developed at our institute, and face visual analog scale were used to measure the emotional state and subjective feelings before and after the trial. The degree of emesis was measured using a visual analogue scale after the experience. We set up the system in a room in the outpatient clinic of the National Cancer Center New Hospital Building. Results: The decreases in the fatigue score and emesis score 3–5 days after chemotherapy were statistically significant (both p 〈 0.05) and carry-over effects were detected. Conclusions: BSW intervention therapy is an effective way to treat fatigue and emesis. This virtual reality system is a new therapeutic method that can be used in palliative medicine.

    Notes: Abstract Purpose: To investigate the effect of understanding their own disease by patients with metastatic breast cancer on their survival potential after being informed by their physician. Patientsandmethods: Two hundred and fourteen women with metastatic breast cancer who participated in a multi-institutional, randomized phase III trial (Japan Clinical Oncology Group (JCOG) Study 8808) were asked whether they understood their own disease after being given information about the clinical trial. They were classified into two groups on the basis of whether they understood or not. We estimated their survival after the time of registration and derived relative hazard ratios from Cox's proportional hazards model. Results: There were 190 patients in the ‘better understanding’ group and 24 in the ‘poor understanding’ group. Median survival times after registration were 28.3 and 16.1 months, respectively. The ‘better understanding’ group showed a significant difference from the ‘poor understanding’ group (p=0.016). In multivariate regression analysis, patients who did not understand still showed poorer survival than those who understood (hazard ratio = 2.09; 95% confidence interval (CI) 1.16–3.78; p=0.014)

    Notes: Abstract Objectives: To investigate the prevalence of, and risk factors for psychological distress following first recurrences of breast cancer. Patients and methods: The sample was drawn consecutively from the inpatient and outpatient populations of the National Cancer Center Hospital in Japan during an 18-month period from July 1996 to December 1997. Of the 56 eligible patients, 55 women aged 30–73 year with recurrent breast cancer participated in the study. The prevalence of psychological distress, including major depressive disorder and adjustment disorders was evaluated according to the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Third edition-revised (DSM-III-R). Risk factors for psychological distress were analyzed with a logistic regression model. Results: Of the 55 subjects, 42 met the DSM-III-R criteria for major depressive disorder or adjustment disorders. Major depressive disorder was seen in 4 (7%), and adjustment disorders in 19 (35%). Logistic regression analysis showed that a disease-free interval of less than 24 months significantly predicted a diagnosis of major depressive disorder or adjustment disorders (odds ratio 5.28, 95% confidence interval; 1.28–21.8, p=0.02). Conclusions: These results suggest that it is important for all oncology staff to pay careful attention to the psychological health of patients who have been informed of their cancer recurrence, and that some psychosocial intervention is necessary for preventing distress in patients facing early recurrence.
