Multicenter Study[Talking about home hospices with terminally ill cancer patients -- a multicenter survey of bereaved families].
Communicating with patients is clearly an integral part of physicians' practice, and introducing home hospice care is sometimes a difficult task for oncologists. The primary aims of this study were to clarify family-reported degree of emotional distress and the necessity for improvement in communication when introducing home hospice care, and to identify factors contributing to distress levels. ⋯ In receiving information about transition of home care, a considerable number of families experienced high levels of emotional distress and felt a need for improvement in the communication style. This study proposes 6 strategies to alleviate family distress.

Multicenter Study[Validity of recommended minimum dose of prior morphine to initiate transdermal fentanyl patch in prescribing information - multicenter survey of on prescriptions by palliative care specialists in Japan].
For initiating the minimum-size (0.25 microg/hour) transdermal fentanyl patch (TDF), 45 mg a day of oral morphine is the recommended minimum dose (RMD) in Japan according to the prescribing information. However, little is known about the validity of the RMD, and we can presume there are many cases where clinicians are inclined to initiate the minimum-size TDF at the early stage contrary to the RMD due to the high morbidity rate of digestive system cancer in Japan. In order to verify the validity of the RMD, we collected 71 retrospective cases where the minimum-size TDF was initiated against the restriction of RMD. ⋯ According to the Numeric Rating Scale (from 0: no pain to 10: the worst pain), the pain intensity decreased from 6.6 on the 1st day to 2.8 on the 2nd day, 3.3 on the 3rd day, and 2.9 (p < 0.001) on the 4th day. We conclude that, although introducing the minimum-size TDF against the RMD served to decrease the pain intensity,it raised the side effects on the respiratory system even when prescribed by palliative care specialists. Therefore,the RMD regulation is valid for general practitioners from a medical safety standpoint.

Randomized Controlled Trial Multicenter Study Comparative Study[A randomized controlled study comparing uracil-tegafur (UFT)+tamoxifen (UFT+TAM therapy) with cyclophosphamide+adriamycin+5-fluorouracil (CAF therapy) for women with stage I , II, or IIIa breast cancer with four or more involved nodes in the adjuvant setting].
We performed a controlled study to compare the response to cyclophosphamide (CPA), adriamycin (ADM), and fluorouracil (5-FU) (CAF therapy) with that to uracil-tegafur (UFT) plus tamoxifen (TAM) (UFT+TAM therapy), when given as postoperative adjuvant therapy to women with breast cancer. The patients were registered from September 1991 through February 1995 at 51 institutions in the Kinki district of Japan. All patients had stage I, II, or IIIa breast cancer with four or more lymph-node metastases and underwent mastectomy. ⋯ The 5-year relapse-free survival rate was higher in the UFT+TAM group (61.8%) than in the CAF group (46.3%; p=0.07, logrank test). As for adverse events, the rates of leukopenia, anorexia, nausea and vomiting, general malaise, and hair loss were lower in the UFT+TAM group than in the CAF group. These results suggest that long-term treatment with UFT+TAM may be a useful alternative adjuvant therapy for the management of breast cancer, especially in elderly patients.

Multicenter Study[Efficacy and safety of monotherapy with temozolomide in patients with anaplastic astrocytoma at first relapse--a phase II clinical study].
The efficacy and safety of temozolomide were evaluated in 32 patients with anaplastic astrocytoma at first relapse. Temozolomide was administered orally once daily for the first five days of a 28-day cycle, at a dose of 150 or 200 mg/m(2)/day. The response rate determined by independent central review of MRI was 34% (95% confidence interval: 18.6%-53.2%), with 3 complete response and 8 partial response. ⋯ The incidence of constipation (50%) and nausea (25%) was high,but these events were all mild or moderate in severity except in one subject with constipation,and could be managed with standard laxatives and antiemetics. The main laboratory test abnormalities (total incidence and incidence of grade 3/4 change) were lymphocytopenia (50%, 25%), neutropenia (47%, 6%), leukopenia (38%, 3%), thrombocytopenia (31%, 9%), and increased GPT (25%, 3%). Temozolomide was shown to have good efficacy and tolerability in patients with anaplastic astrocytoma at first relapse.

Randomized Controlled Trial Multicenter Study Clinical Trial[Multicenter comparative study of the recurrence-inhibitory effect of oral fluoropyrimidine drugs in patients with colorectal cancer following curative resection].
HCFU and UFT were reported effective in adjuvant chemotherapy for colorectal cancer. This investigation was planned as a randomized study to compare the usefulness of combination therapies with mitomycin C (MMC)+HCFU and MMC+UFT as postoperative adjuvant chemotherapy in patients with colorectal cancer following curative resection, in terms of survival rate, recurrence rate, and adverse drug reactions. A total of 501 patients consisting of 252 patients with stage III/IV colon cancer (Colorectal Cancer Handling Rules, 4th Ed.) for which macroscopic curative resection was possible and 249 patients with stage II/III/IV rectal cancer (ibid, 4th Ed.) were registered from 40 participating institutions. ⋯ The administration completion rates were good, and no serious adverse drug reactions were observed for either therapy. It was thus considered that both therapies could be administered safely, and both were useful as postoperative adjuvant chemotherapies for colorectal cancer. It is considered necessary to compare them with standard therapies in Western countries in the future.
