Multicenter Study
Multicenter outcome study of cancer patients admitted to the intensive care unit: a probability of mortality model.
To develop prospectively and validate a model for probability of hospital survival at admission to the intensive care unit (ICU) of patients with malignancy. ⋯ We report a disease-specific multivariable logistic regression model to estimate the probability of hospital mortality in a cohort of critically ill cancer patients admitted to the ICU. The model consists of 16 unambiguous and readily available variables. This model should move the discussion regarding appropriate use of ICU resources forward. Additional validation in a community hospital setting is warranted.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of single-dose oral granisetron versus intravenous ondansetron in the prevention of nausea and vomiting induced by moderately emetogenic chemotherapy: a multicenter, double-blind, randomized parallel study.
The antiemetic effectiveness and safety of single-dose oral granisetron were compared with intravenous (I.V.) ondansetron in chemotherapy-naive patients who received moderately emetogenic chemotherapy. ⋯ A single oral dose of granisetron (2 mg) resulted in equivalent levels of antiemetic protection as I.V. ondansetron (32 mg). Both agents were well tolerated, although more dizziness and abnormal vision were reported with ondansetron. Because the two antiemetic regimens exhibited equivalent efficacies, additional factors such as convenience and cost of therapy should be considered.

Randomized Controlled Trial Clinical Trial
Lumpectomy and radiation therapy for the treatment of intraductal breast cancer: findings from National Surgical Adjuvant Breast and Bowel Project B-17.
In 1993, findings from a National Surgical Adjuvant Breast and Bowel Project (NSABP) trial to evaluate the worth of radiation therapy after lumpectomy concluded that the combination was more beneficial than lumpectomy alone for localized intraductal carcinoma-in-situ (DCIS). This report extends those findings. ⋯ Through 8 years of follow-up, our findings continue to indicate that lumpectomy plus radiation is more beneficial than lumpectomy alone for women with localized, mammographically detected DCIS. When evaluated according to the mammographic characteristics of their DCIS, all groups benefited from radiation.

Clinical Trial
Phase II study of carmustine, dacarbazine, cisplatin, and tamoxifen in advanced melanoma: a Southwest Oncology Group study.
The combination of carmustine (BCNU), dacarbazine (DTIC), cisplatin (DDP), and tamoxifen (Tam) has been reported in small series to provide a response rate of 50%, but with significant myelosuppression and risk of thromboembolic complications. We performed this phase II study to assess the antitumor activity and important toxicities of this combination in the cooperative group setting. ⋯ The activity of this regimen is in the range reported for single agents or DTIC plus DDP, and the addition of BCNU and Tam appears to increase toxicity. We do not recommend this combination for routine treatment of advanced melanoma or as the control arm in randomized studies of combination therapy.

Bone marrow involvement in patients with malignant lymphoma is considered a sign of generalized disease with less favorable prognosis. Bone marrow biopsy (BMB), which represents the standard diagnostic procedure, however, is associated with a high rate of false-negative findings, which may lead to errors in management. The present study was undertaken to investigate the efficacy of positron emission tomography (PET) with 18-F-fluorodeoxyglucose (FDG-PET) as a new method to evaluate bone marrow involvement in patients with malignant lymphoma. ⋯ The results indicate that FDG-PET has a high potential to detect bone marrow involvement in malignant lymphoma. Besides confirming lesions found at BMB, FDG-PET provided additional information, which, in eight of 78 patients (10.3%), led to an upgrade of the tumor stage.
