The value of medical student research: the experience at Stanford University School of Medicine.
At Stanford University School of Medicine, students are encouraged to conduct research, requiring a substantial amount of funding and effort on the part of teaching staff. We questioned one graduating class and all medical teachers to determine the value of the research experience to students, as well as staff satisfaction. Seventy-three per cent of students and 80% of teaching staff responded. Ninety per cent of students had performed research resulting in at least one published manuscript for 75% and a presentation at a national meeting for 52%. Almost all thought the experience taught them to ask questions, review the literature critically, and analyse data. Three-quarters responded that the experience motivated them to pursue further research, and 60% indicated that they plan a full-time academic career. The majority of teaching staff who worked with students found it rewarding and thought the student had had a valuable experience. We conclude that our curriculum provides a positive opportunity for students to develop an investigative approach to medical problems.

Stanford University's experience with managed competition.
Stanford University has a "managed competition" model of health insurance. Stanford contributes the cost of the low-cost plan, and employees are responsible for premium differences between this plan and other offerings. Each employee gets what he or she wants and is willing to pay for, and everyone has low-cost access to health insurance. Stanford risk-adjusts the premiums based on age and sex and plans soon to adjust including prescription drug data. In the past five years, premiums have risen rapidly, in line with the rest of the market. For competition to transform the delivery system, most employers in the region must adopt managed competition.

Thirty years of cardiac transplantation at Stanford university.
BACKGROUND: The experience with 30 years of cardiac transplantation at Stanford University Medical Center was reviewed. A total of 954 transplants were performed in 885 patients. Patients were divided into 3 groups based on immunosuppression received: group I, no cyclosporine (INN: ciclosporin) (n = 201) (January 1968-November 1980); group II, cyclosporine (n = 248) (December 1980-June 1987); and group III, cyclosporine + OKT3 (n = 436) (July 1987-March 1998). RESULTS: The 1-, 5-, and 10-year actuarial survivals were 68%, 41%, and 24% (group I); 80%, 57%, and 37% (group II); and 85%, 68%, and 46% (group III) (I vs II, P <.01; I vs III, P <.005; and II vs III, P <.005). The 1-, 5-, and 10-year actuarial death rates from rejection were 8%, 12%, and 14% (group I); 5%, 7%, and 7% (group II); and 2%, 5%, and 5% (group III) (I vs II, P = not significant; I vs III, P <.005; and II vs III, P <.005). The 1-, 5-, and 10-year actuarial death rates from infection were 25%, 43%, and 50% (group I); 8%, 17%, and 29% (group II); and 6%, 11%, and 16% (group III) (I vs II, P <.005; I vs III, P <.005; and II vs III, P <.05). The 1-, 5-, and 10-year actuarial death rates from graft coronary artery disease were 0%, 5%, and 13% (group I); 0%, 12%, and 19% (group II); and 1%, 6%, and 9% (group III) (I vs II, P <.01; I vs III, P <.005; and II vs III, P = not significant). There have been 69 retransplants in 67 patients with 1-, 5-, and 10-year actuarial survivals of 49%, 27%, and 15%, respectively. CONCLUSIONS: The evolution of 3 decades of experience with cardiac transplantation has resulted in improved overall survival. The incidence of rejection and of death from infection and graft coronary artery disease have decreased over time, primarily as a result of improvements in immunosuppression and in the prevention and treatment of infection. Continued advances in perioperative management and the development of more specific, less toxic immunosuppressive agents could further refine this initial experience and improve the survival and quality of life of patients after cardiac transplantation.

Treatment results and prognostic factors of advanced T3--4 laryngeal carcinoma: the University of California, San Francisco (UCSF) and Stanford University Hospital (SUH) experience.
PURPOSE: To review the UCSF-SUH experience in the treatment of advanced T3--4 laryngeal carcinoma and to evaluate the different factors affecting locoregional control and survival. METHODS AND MATERIALS: We reviewed the records of 223 patients treated for T3--4 squamous cell carcinoma of the larynx between October 1, 1957, and December 1, 1999. There were 187 men and 36 women, with a median age of 60 years (range, 28--85 years). The primary site was glottic in 122 and supraglottic in 101 patients. We retrospectively staged the patients according to the 1997 AJCC staging system. One hundred and twenty-seven patients had T3 lesions, and 96 had T4 lesions; 132 had N0, 29 had N1, 45 had N2, and 17 had N3 disease. The overall stage was III in 93 and IV in 130 patients. Seventy-nine patients had cartilage involvement, and 144 did not. Surgery was the primary treatment modality in 161 patients, of which 134 had postoperative radiotherapy (RT), 11 had preoperative RT, 7 had surgery followed by RT and chemotherapy (CT), and 9 had surgery alone. Forty-one patients had RT alone, and 21 had CT with RT. Locoregional control (LRC) and overall survival (OS) were estimated using the Kaplan--Meier method. Log-rank statistics were employed to identify significant prognostic factors for OS and LRC. RESULTS: The median follow-up was 41 months (range, 2--367 months) for all patients and 78 months (range, 6--332 months) for alive patients. The LRC rate was 69% at 5 years and 68% at 10 years. Eighty-four patients relapsed, of which 53 were locoregional failures. Significant prognostic factors for LRC on univariate analysis were primary site, N stage, overall stage, the lowest hemoglobin (Hgb) level during RT, and treatment modality. Favorable prognostic factors for LRC on multivariate analysis were lower N stage and primary surgery. The overall survival rate was 48% at 5 years and 34% at 10 years. Significant prognostic factors for OS on univariate analysis were: primary site, age, overall stage, T stage, N stage, lowest Hgb level during RT, and treatment modality. Favorable prognostic factors for OS on multivariate analysis were lower N stage and higher Hgb level during RT. CONCLUSION: Lower N-stage was a favorable prognostic factor for LRC and OS. Hgb levels > or = 12.5 g/dL during RT was a favorable prognostic factor for OS. Surgery was a favorable prognostic factor for LRC but did not impact on OS. Correcting the Hbg level before and during treatment should be investigated in future clinical trials as a way of improving therapeutic outcome in patients with advanced laryngeal carcinomas.

Adult lymphoblastic lymphoma: high incidence of central nervous system relapse in patients treated with the Stanford University protocol.
Twelve adult patients with non-leukaemic lymphoblastic lymphoma were treated with combination chemotherapy and central nervous system prophylaxis according to the protocol developed at Stanford University. Despite strict adherence to the Stanford protocol, 4 of 12 patients relapsed in the CNS, all with meningeal disease. Only four of the 12 patients are in continuing complete remission 6 to 88 months from the completion of induction therapy. These results are inferior to those previously reported for this regimen, and fail to confirm the high rate of control of CNS disease.

Electron-beam therapy for mycosis fungoides: the Stanford University experience.
The use of high-dose electron-beam therapy for mycosis fungoides at Stanford University is reviewed. Since 1966, 140 patients have been treated in this fashion. Their clinical characteristics including initial extent of disease are reviewed. The results of routine staging studies are examined. Eighty-four percent of the patients achieved an initial complete remission; this was inversely related to the initial extent of skin involvement. The overall survival rate was 46% at 10 years with the major prognostic factor being the initial extent of skin involvement. Other factors which had an influence on the patient's progrnosis included the presence of palpable adenopathy, the patient's age, the achieving of an initial complete remission, the initial dose of electron-beam therapy, and the treatment with adjuvant topical mechlorethamine. The development of a rationale for the treatment of patients with all stages of mycosis fungoides based upon these clincal observations is discussed.

Radiation therapy for primary squamous cell carcinoma of the vagina: Stanford University experience.
A retrospective analysis of 38 patients with primary squamous cell carcinoma of the vagina seen at Stanford University Medical Center from 1958 to 1984 was undertaken. Patients were analyzed with regard to symptoms, stage, treatment techniques, survival, patterns of failure, and complications. Eighteen patients were classified as FIGO Stage I, 5 as Stage II, 10 as Stage III, and 5 as Stage IV. The 5-year disease-free survival was 94% in Stage I, 80% in Stage II, 50% in Stage III, and 0% in Stage IV. Five patients (13%) had eight major complications secondary to treatment. Only 2 of 23 patients with Stage I or Stage II disease developed a recurrence. There was a significant correlation between dose and response in patients treated with radiotherapy.

Coccidioidomycosis in compromised hosts. Experience at Stanford University Hospital.
To determine the frequency and clinical characteristics of infection with Coccidioides immitis in immunosuppressed patients at Stanford University Hospital, clinical records of 14 years were examined. Thirteen cases met the diagnostic criteria. Half had Hodgkin's disease. In six the infection was disseminated; five of the six died early in the course of their infectious illness, frequently without diagnosis. Conclusions include: 1. The occurrence of coccidioidomycosis in immunosuppressed patients seen at institutions in or adjacent to the endemic area is not as rare as the literature suggests. 2. Dissemination is frequently explosive and the radiographic appearance of pulmonary involvement may appear late. Widespread pulmonary dissemination may occur within 24 hours after a negative x-ray. 3. Although the skin test loses its diagnostic value, the serology remains valid. Thus immunosuppressed patients with febrile illnesses (with or without radiographically evident pulmonary involvement) who have a history of travel to an endemic area should have serological examinations. 4. Lymphocytopenia correlates with risk of dissemination of coccidioidomycosis. 5. The administration of immunsuppressive chemotherapy correlates with such risk while radiotherapy and the malignant or non-malignant nature of the disease do not.

Liver transplantation for fulminant hepatitis at Stanford University.
BACKGROUND: To review the clinical characteristics and outcomes of 26 patients evaluated for liver transplantation for fulminant hepatic failure at Stanford University and Lucile Packard Children's Hospital in an attempt to identify risk factors and prognostic predictors of survival. METHODS: A retrospective review of the records of 26 consecutive patients who were evaluated for possible liver transplantation for acute liver failure from May 1, 1995, to January 1, 2000. Pretransplant patient demographics and clinical characteristics were collected, and the data were analyzed by univariate and multivariate analysis. RESULTS: Clinical assessment of encephalopathy did not predict outcome. Patients with abnormal computed tomography (CT) of the brain had a twofold increase in mortality compared with those patients with normal studies (p = 0.03). Patients requiring mechanical ventilation and continuous venovenous hemofiltration (CVVH) also had a poor prognosis. CONCLUSION: Predictors of poor outcome after fulminant hepatic failure include abnormal CT scan, mechanical ventilation, and requirement for hemofiltration.

Stage I to IIB Hodgkin's disease: the combined experience at Stanford University and the Joint Center for Radiation Therapy.
The treatment records of 180 patients with pathological stage (PS) IB to IIB Hodgkin's disease treated at Stanford University Medical Center (SUMC) or the Joint Center for Radiation Therapy (JCRT) were reviewed. Pretreatment characteristics were analyzed to assess their influence on survival and freedom from relapse (FFR). The two most important disease characteristics predictive of relapse were the number and type of B symptoms present and the mediastinal mass ratio (MMR). Patients with both fevers and weight loss had a 7-year survival and FFR of only 57% and 48%, respectively. The poor prognosis in this group was apparent for treatment with either radiation (XRT) alone or combined modality therapy (CMT). Patients with night sweats only had no adverse effect of B symptoms on outcome. Patients with a MMR greater than 1/3 had a 7-year FFR of only 58% after XRT, but 79% after CMT (P = .12). The 7-year survivals for these patients were 85% and 88%, respectively. CMT improved the FFR of the entire group of 180 patients when compared with XRT (7-year FFR 86% and 74%, respectively, P = .02); however, survival in the two treatment groups was similar (88% and 89%). Among patients treated with radiation alone, there was a similar survival and FFR irrespective of whether pelvic irradiation was included in the initial treatment fields.

Astrocytoma in children: 14 years' experience at Stanford University Medical Center.
Between January 1, 1971 and December 31, 1984, 50 children (31 males, 19 females) ages 3 1/2 months to 18 years with primary CNS astrocytoma were seen in the Department of Therapeutic Radiology, Stanford University Medical Center. The actuarial survival and freedom from relapse (FFR) for the treated group is 46%, with a median follow-up of 7.2 years and a maximum follow-up of 14 years. The majority of relapses occurred within the first 2 years of diagnosis, and all relapses occurred at or adjacent to the initial site of tumor. Multivariate analysis revealed that factors correlated with poor survival are high histologic grade (including presence of necrosis) and primary tumor in the brain stem, while the only important prognostic factor associated with an adverse FFR is high histologic grade. Age, sex, degree of surgical resection, and total radiation dose to the tumor are not correlated with outcome. Patients with high-grade tumor were selected to receive whole brain irradiation and/or adjuvant chemotherapy; therefore, the findings of apparent poor prognosis associated with whole brain irradiation and adjuvant chemotherapy actually reflect patient selection. Current therapy is adequate for only half of children with astrocytoma. Thus, continued development of innovative therapies is indicated, particularly for those children with adverse prognostic factors.

Infectious disease management of adult leukemic patients undergoing chemotherapy: 1982 to 1986 experience at Stanford University Hospital.
PURPOSE: The purpose of this study was to determine the recent incidence of infection and to evaluate antimicrobial usage among adult leukemic patients undergoing chemotherapy for acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) at Stanford University Hospital. PATIENTS AND METHODS: The records of 142 adult patients from a consecutive series of 226 induction or consolidation/maintenance chemotherapy courses for AML or ALL between 1982 to 1986 were reviewed retrospectively. Data were analyzed to compare the infectious disease complications and antimicrobial usage for patients receiving identical chemotherapy for a specific phase of leukemia treatment. Evaluation for each chemotherapy course included assessments for the following: compliance with criteria for initiating antibiotics, incidence of infection that was documented by culture or clinical criteria, predictive value of surveillance cultures, incidence of superinfection, survival outcomes, antimicrobial usage, antibiotic-related adverse effects, and cost for antibiotics and diagnostic studies. RESULTS: Antimicrobials were employed in 190 (84%) of 226 chemotherapy courses. Broad-spectrum antibiotics were regularly begun within the first five days of admission and they were continued for an average of 3.5 weeks until the granulocyte count was greater than 1,000/microL after discontinuation of chemotherapy. There were no differences in the types of infection or outcomes among the patient groups. There was only a 37% rate of documented infections by culture or clinical signs among these patients during their entire hospital stay. Bacterial infections, especially those caused by coagulase-negative staphylococci in patients with Hickman catheters, accounted for 93% of the episodes. Viral and fungal infections accounted for 4% and 3% of documented cases, respectively, and occurred more than 10 days after the institution of broad-spectrum antibiotic therapy. A total of 922 different antimicrobials were employed in 190 courses (average 4.9 per course). The rationale for excessive usage and multiple changes was a persistent or intermittent fever, rather than documented infection(s). This practice led to usage of more broad-spectrum and expensive antibiotics. Further analyses indicate that the greater number of antibiotics employed correlated with apparent increased toxicity, especially renal and hepatic adverse reactions. These toxicities were associated with higher rates of fatal outcomes, i.e., 12 (39%) of 31 patients died with antibiotic-associated hepatic and/or renal insufficiency, compared with 12 (7.5%) of 159 patients who died without antibiotic-associated organ damage. CONCLUSION: Excessive antibiotic usage and multiple antibiotic changes among adult leukemic patients undergoing chemotherapy appear to increase the risks of adverse hepatic and renal effects and death. Furthermore, this practice leads to use of more broad-spectrum and expensive antibiotics...
