Abstract
Decision theory was used to calculate the optimum treatment of microscopic squamous cervical cancer using probabilities obtained from an exhaustive literature review and a range of plausible value estimates. This showed that if there is no vascular involvement, survival is maximised by conservative treatment if tumour invasion is less than 3 mm while treatment by radical surgery results in maximal survival rates if the tumour invasion is over 3 mm. Radical surgery also maximises survival for smaller lesions where lymph channel involvement is present, especially if a surgical mortality at the lower end of the reported range is assumed. Refinement of our analysis to include an assessment of patient values showed that these conclusions are still valid regardless of the patient's relative preference for death from surgery or death from cancer. However, the wish to preserve fertility sharply reduces the overall net benefit of surgery. Conservative treatment becomes the preferred option for all microinvasive lesions even for patients who are prepared to trade-off a small (e.g. 2%) risk of death in order to retain their fertility.

Abstract
The molecular and cellular processes underlying photoreceptor degeneration in retinitis pigmentosa (RP) are unknown. We have investigated gene expression in diseased retinas using differential hybridization screening of a retinal cDNA library with probes derived from normal and RP retinal RNA. Most differential clones detected corresponded to transcripts absent from the dystrophic state, including e.g. opsin. However, one clone was noticeably increased in RP in comparison with the control: partial sequencing showed it encoded clusterin. Increased expression of clusterin has been identified in several cases of tissues undergoing apoptosis (programmed cell death), and our finding suggests that the degenerative changes in advanced RP may represent another example of apoptosis, possibly with common causative mechanisms.

Abstract
Piritrexim (PTX) is a newly developed lipid-soluble folate antagonist that crosses the cell membrane by a simple, rapid, carrier-independent diffusion process. A Phase II study was conducted to evaluate the activity of PTX in 34 patients with previously chemotherapy-naive squamous cell cancer of the head and neck area (SCCHN). Among them, 30 patients had received previous radiation therapy and/or surgery. Of 33 patients who could be examined, 3 had a complete response (CR), 6 had a partial response (PR), 11 had no change, and 13 had disease progression. The overall response rate (CR + PR) was 27% (9 of 33; 95% confidence interval, 13% to 46%). The response duration ranged from 36 to 360 + days (median, 162) and was similar to the best studies reported with methotrexate. The three most severe side effects (Grades 3 and 4 by World Health Organization criteria) were leukopenia, thrombocytopenia, and mucositis. These occurred in 41%, 26%, and 15% of the 34 patients, respectively. This study established PTX as an agent with some activity in SCCHN. The use of PTX in combination chemotherapeutic regimens needs to be explored.

Abstract
A new combination of mitoxantrone, folinic acid (leucovorin), and infusional fluorouracil (5-FU) was administered to 57 previously treated patients with metastatic breast cancer to evaluate the response rate, response duration, and toxicity of this regimen. Fifty-three patients who received 313 courses of therapy were assessable for response and toxicity. Median age was 48 years (range, 33 to 80 years), and the patients had received an average of 1.5 chemotherapy regimens before this study. Of 53 assessable patients, 24 (45%, or 42% of all entered patients) experienced partial responses (PRs) with a median duration of 6 months (range, 2 to 13 months). Nine (69%) of 13 assessable patients without prior doxorubicin treatment responded, compared with 15 (38%) of 40 with prior doxorubicin (P less than .05). Toxicity was generally mild with dose reductions necessitated more often by mucositis and/or diarrhea than by myelosuppression. One patient with prior high-dose doxorubicin treatment developed congestive heart failure. The combination of mitoxantrone, leucovorin, and infusional 5-FU is an active and well-tolerated regimen for metastatic breast cancer and deserves further evaluation in patients without prior doxorubicin therapy.

Abstract
The effectiveness of a continuous low dose papaveretum infusion for the relief of postoperative pain was assessed in 29 infants aged 1-6 months nursed on the infant surgical ward following major abdominal surgery. Trained nursing staff were able to adjust the dosage within prescribed guidelines and satisfactory analgesia was obtained with a regimen which delivered up to 0.0375 mg/kg/hour, approximately half the dose recommended in children older than 12 months. There was one case of clinically significant respiratory depression.

Abstract
Regional cerebral blood flow (CBF) has been measured in eight anaesthetized, exteriorized, fetal sheep between 58 and 62 days gestation; four were controls, four were hypercapnic (PaCO2 = 78 +/- 5 mmHg, mean +/- S.E.M.). Blood flow values were calculated from quantitative autoradiography following the infusion of [14C]iodoantipyrine into a cannulated fetal placental vein, for the cerebellum, medulla, and five layers of the developing neocortex: cortical plate (CP), subplate zone (SP), intermediate zone (IZ), subventricular zone (SV), and the ventricular zone (VZ). The highest control CBF rates were recorded in the cortical plate (49.3 +/- 7.4 ml min-1 (100 g)-1, mean +/- S.E.M., posterior cortex) and in the ventricular zone (40.5 +/- 4.8, posterior cortex), which at this stage of development are the regions of greatest cell density. The lowest CBF rates were recorded in the subplate zone (23.8 +/- 6.8, anterior cortex) and in the intermediate zone (23.4 +/- 7.6, anterior cortex), which are the regions of lowest cell density. Experimentally induced hypercapnia increased CBF in all brain regions and enhanced the regional pattern of flow. The results provide evidence that CBF in the immature fetal sheep brain (at 58-62 days gestation) is heterogeneous under both control and hypercapnic conditions (especially in the neocortex). Blood vessels of the fetal sheep brain at this early stage of development are clearly responsive to CO2.

Abstract
A fetuin-like glycoprotein (FLG) has been shown to be present in early cortical plate cells in the developing brain of the tammar wallaby (Macropus eugenii). The developmental sequence of the occurrence of glycoprotein-positive fibres and cells in the dorsolateral telencephalic wall from newborn to day 40 is described. The level of FLG in CSF (cerebrospinal fluid) and plasma of the tammar wallaby has also been measured during pouch life. The presence of FLG in early postnatal fibre systems and in some cells in the primordial plexiform layer, as well as in early cortical plate cells of the tammar is similar to that of fetuin in fetal brain in sheep, pig and cow, and alpha 2HS glycoprotein in human fetal brain. The sequence of appearance of FLG-positive cells during neocortical development in the tammar is strikingly similar to that of a transient population of early cortical plate cells previously described in fetal cat and sheep cortex. During postnatal development, levels of FLG in tammar plasma and CSF follow a pattern different from that of other species. The developmental expression of all three related glycoproteins in their respective species is discussed.

Abstract
This paper describes apparatus and methods for measuring uptake of inhaled vapors in the nose and lungs of dogs. The system allows sampling of air from the trachea at specific times during inspiration and expiration without surgical manipulation of the animal, thus allowing repeated studies in the same animal. During exposure, the dogs are anesthetized and cyclic respiratory patterns are maintained by means of an external respirator. A pneumotachograph installed in the exposure line is connected to a respiratory monitoring system that both monitors the dog's respiratory pattern and triggers sampling at specific times in the respiratory cycle. Air sampling, both at the nose and within the trachea, can be done during the entire breathing cycle or during specific portions of it. Vapors are sampled at a point just external to the dog's nose and from within the trachea through a modified endotracheal tube. To develop and demonstrate the system, three beagle dogs were exposed to 2,4-dimethylpentane and 1.3-dioxolane at nominal vapor concentrations of 500 ppm; vapor sampling was triggered for the entire inspiratory and expiratory portions of the breathing cycle during 10-min exposures. After correcting data to account for vapor that desorbed from the nasal passages during exhalation (after initially being absorbed in the nose during inhalation), net nasal uptake of 2,4-dimethylpentane was 28.3%; net nasal uptake of 1,3-dioxolane was 66.6%. Lung uptake was 14.0% for 2,4-dimethylpentane and 2.1% for 1,3-dioxolane. The system was developed for use with dogs, but it can be adapted for use with any animal species that can be intubated with endotracheal vapor sampling tubes.

Abstract
The standard of obstetrics care by general practitioners in Bradford was assessed by reviewing the case records of all women who in 1988 were booked for delivery under their general practitioner but subsequently required transfer to consultant care. A total of 5885 women were delivered in Bradford during 1988. Of 1289 booked under their general practitioner, 637 required transfer to consultant care. In 259 cases transfer occurred during labour; only 37 of these women were visited by their general practitioner. Many of the problems that precipitated transfer were predictable and some were considered preventable: 263 of the women transferred were considered unsuitable for booking by general practitioners. The perinatal mortality among women booked under their general practitioner was 10.1/1000 and the stillbirth rate 7.8/1000. These figures are high and suggest a need for tighter controls over the qualifications and experience of doctors participating in a fully integrated system of obstetric care.

Abstract
The current AIDS epidemic continues unabated. The steadily increasing number of HIV-infected persons in United States, and the prolonged latent period from time of infection to the development of clinical signs and symptoms, increase the likelihood of the undiagnosed patient arriving a t the dental office for treatment. Keen examination skills are required to recognize the early manifestations of infection. The purpose of this article is to present the clinical features of HIV infection and indicator oral diseases, and to illustrate the importance of the dental hygienist in providing early recognition of the very subtle clinical findings often associated with AIDS Related Complex.

Abstract
In order to assess long-term outcome of patients with localized (stage I or II) diffuse large-cell lymphoma treated with initial combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without involved-field radiotherapy following chemotherapy, we combined data from two prospective trials in Tucson (64 patients) and Vancouver (78 patients). Follow-up on 142 patients was updated and a variety of potential pretreatment prognostic factors were analyzed for impact on outcome. One hundred forty patients (99%) achieved a complete remission and there were no differences in outcome between institutions. Twenty-three patients have relapsed and 22 have died from lymphoma at a median follow-up of 4.4 years, resulting in an overall relapse-free survival of 82% at 5 years. There was no treatment-related mortality and were no instances of late cardiac toxicity or leukemia. Of the following potential pretreatment prognostic factors (age, stage, "B" symptoms, extranodal disease, gastrointestinal tract involvement, bulky disease, or disease above or below the diaphragm), only stage affected relapse-free survival (RFS) (P = .16) and survival (.003). Among 34% of patients over age 65, outcome was similar to younger patients. RFS for 108 patients treated with CHOP plus radiotherapy was not significantly superior to the use of CHOP alone in 34 patients (P = .2).

Abstract
A phase II trial of combination chemotherapy with mitoxantrone, cisplatin, and methyl-glyoxal bix-guanylhydrazone (MGBG) was conducted in 32 patients with unfavorable histology malignant lymphoma. All patients had relapsed after only one prior chemotherapy regimen (CHOP--56%; mBACOD--28%). There were three complete and eight partial responses (overall response rate--34%) among 32 eligible patients. The median duration of remission was 6.0 months. Severe granulocytopenia was common, with 19/32 patients (63%) suffering life-threatening, and 1/32 (3%) suffering fatal, granulocytopenia. We conclude that mitoxantrone-cisplatin-MGBG has modest activity as salvage treatment in malignant lymphoma patients, but produces severe toxicity.

Abstract
We prospectively measured the on-scene time, transport time, and IV line starting time for 97 patients receiving paramedic care in an urban region during an 18-month period. The overall success rate for IV line placement was 91%, and the average successful IV line starting time was 2.5 minutes. En route IV line attempts had similar success rates and starting times. The on-scene IV line starting times were shorter than the transport times in 86% of patients. We conclude that definitive IV line medical therapy, when available, can be delivered effectively by paramedics at the scene. We also conclude that en route IV line placement is feasible in trauma victims.

Abstract
Bacterial counts obtained by using a new Anopore inorganic membrane filter were 21 to 33% higher than those obtained by using a Nuclepore polycarbonate membrane filter. In addition, the inorganic filter had higher flow rates, permitting lower vacuum pressures to be used, while the intrinsically flat, rigid surface resulted in easier focusing and sharp definition of bacteria across the whole field of view.

Abstract
1. The protein composition and concentrations of total protein in cerebrospinal fluid (CSF) and plasma of opossum (Monodelphis domestica) from birth until adulthood have been estimated. 2. Total protein in CSF increased from birth to a peak concentration between 5 and 10 days (500 mg/100 ml) after which it declined rapidly. 3. Total protein in plasma started at a low level at birth (below 400 mg/100 ml) and increased progressively to the adult value (8500 mg/100 ml). 4. Proteins identified in CSF and plasma were: albumin, alpha 1 antitrypsin, transferrin, alpha 2 macroglobulin, lipoproteins and immunoglobulin G. A fetal protein, probably alpha-fetoprotein, has been identified. 5. The only plasma proteins found within the brain, even in the very immature newborn of this species, appeared to have an intracellular rather than an extracellular distribution. This indicates that the blood-brain barrier is present very early in development and that there is also a CSF-brain barrier that appears to exclude CSF protein from brain extracellular space.

Abstract
High-dose interleukin-2 (IL-2) with or without lymphokine-activated killer (LAK) cells has been reported to have activity in certain solid tumors, but toxicity has usually required hospitalization for administration. The purpose of this trial was to determine the antineoplastic effect and toxicity of IL-2 administered at a lower dose in an outpatient setting. Eligibility criteria included measurable disease, Karnofsky performance greater than or equal to 70%, age greater than 18 years, and adequate bone marrow, renal, and hepatic function. The median age of 35 patients was 56 years (range, 20 to 75). Diagnoses included malignant lymphoma (ML), (nine patients), chronic lymphocytic leukemia (CLL) (eight), melanoma (eight), colorectal cancer (six), renal cancer (two), and breast cancer (two). The initial 18 patients were treated with 1 mg/m2 (3 x 10(6) U/m2 intravenous [IV] bolus) for five days every other week for a total of 4 treatment weeks (8 weeks total). The subsequent 17 patients were treated with 0.5 mg/m2 (1.5 x 10(6) U/m2). All patients were evaluable for toxicity, and 26 for tumor response. Toxicities included fatigue (71%), nausea (69%), hypotension (54%), fever (51%), chills (40%), weight gain (37%), pruritus or rash (31%), dyspnea (14%), azotemia (6%), confusion (6%), thrombocytopenia (6%), and myocardial infarction (3%). Four patients died from apparently unrelated causes within the first 2 weeks of treatment. Treatment was discontinued before the completion of 8 weeks of treatment because of progressive disease (12 patients), severe hypotension (three), azotemia (one), myocardial infarction (one), early death (four), and miscellaneous causes (two). IL-2 at 1 mg/m2 IV for five days is associated with moderate toxicity, but a dose of 0.5 mg/m2 is tolerable for outpatient administration. Three partial responses (PR) and one minor response (MR) lasting 1 to 17+ months have been observed in 12 patients with ML and CLL evaluable for response. One additional MR was observed in a patient with melanoma. IL-2 deserves further study in patients with ML and CLL.

Abstract
Epirubicin is a new anthracycline with a potentially more favorable toxicity profile than the parent compound, doxorubicin. Accordingly, the feasibility and toxicity of 6 courses of adjuvant chemotherapy with cyclophosphamide (C), epirubicin (E), and 5-fluorouracil (F) were assessed in 10 patients with Stage 2 (node positive) breast cancer. Doses of C and F were 600 mg/m2 and E was 75 mg/m2. Moderate granulocytopenia (median count = 610/mm3) occurred on day 14 of the first 21 day treatment course and was the main toxicity encountered with treatment, although there were no episodes of granulocytopenic fever. Grade 3 or 4 vomiting occurred in 40% and significant alopecia in 30% of patients. Four patients experienced transient asymptomatic decreases in calculated radionuclide cardiac ejection fraction of greater than or equal to 10% but no signs or symptoms of cardiac failure were observed. If epirubicin proves to be less cardiotoxic than doxorubicin, this combination would merit further evaluation as potential adjuvant therapy for early breast cancer.

Abstract
Two related glycoproteins, fetuin in species of the order Artiodactyla (cattle, sheep, pig) and alpha 2HS glycoprotein in the human [(1987) Cell Tissue Res. 248, 33-41] have a very specific distribution in the developing brain. We have isolated and determined the first 15 N-terminal residues of a similarly distributed glycoprotein in the developing brain of the tammar wallaby (Macropus eugenii). The degree of homology is the same between wallaby glycoprotein and alpha 2HS glycoprotein as between fetuin and alpha 2HS glycoprotein (46%). Antibodies made to synthetic peptides of fetuin were used to identify the wallaby glycoprotein. A polyclonal antibody to the purified glycoprotein was used for immunocytochemical identification of brain cells positive for this protein.

Abstract
The Southwest Oncology Group (SWOG) began testing doxorubicin-containing combination chemotherapy in 1972 using the cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) regimen. Subsequent studies, including 350 patients followed for up to 13.3 years, demonstrated that CHOP was curative in 32% of advanced stage, diffuse large cell lymphomas. More recently, promising results from several institutions suggest that new combinations including methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, dexamethasone (m-BACOD), prednisone, methotrexate, doxorubicin, cyclophosphamide, etoposide, cytarabine, bleomycin, vincristine, methotrexate (ProMACE-CytaBOM), and methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, bleomycin (MACOP-B) may be superior to CHOP as gauged by complete response (CR) rates. Consequently, the SWOG developed a strategy to compare these regimens directly with CHOP. In 1984 the SWOG began testing these regimens in sequential group-wide phase II trials to confirm therapeutic activity, establish feasibility with regard to toxicity in a cooperative group setting, and gain experience using the complex schedules and dose-modification schemes. Those phase II studies have been completed, and preliminary results indicate that these regimens are active (CR rates, 53% to 65%) and feasible to administer in a cooperative group setting (fatal toxicity, 2% to 6%). We conclude that these three drug regimens can be administered safely in a cooperative group setting, and the CR rates support the current SWOG comparative trial using CHOP as the standard treatment arm.

Abstract
Some adjuvantly treated patients develop recurrent breast cancer and little is known about the effect of prior adjuvant chemotherapy on subsequent response rates to systemic therapy or on overall survival. We describe our retrospective comparison of 179 patients who received doxorubicin containing adjuvant chemotherapy and developed recurrent breast cancer on University of Arizona Cancer Center clinical trials with 202 non-adjuvantly treated patients entered onto clinical protocols for recurrent or metastatic breast cancer during the same period. Adjuvant failures had a shorter median survival from the date of onset of recurrent disease (18 months versus 28 months, P less than 0.001), a lower response rate to initial combination chemotherapy (38% versus 69%, P = 0.001), and a high incidence of CNS involvement at the time of relapse (11%). In patients having recurrent or metastatic breast cancer, a history of prior adjuvant chemotherapy appears to identify a subgroup who will have a higher incidence of CNS involvement, a lower response rate to chemotherapy and a shorter survival with metastatic disease. These findings may help explain the failure of improved relapse free survival seen in many adjuvant chemotherapy trials to result in improved overall survival.

Abstract
Pretreatment information, type of treatment, and longitudinal follow-up on 1,971 patients with operable breast cancer were used to establish a breast cancer natural history data base (NHDB). Data were available for 957 patients with stage I (node-negative) breast cancer and 1,014 stage II (node-positive) patients. In women with negative nodes, information was available on 759 patients treated at the Milan National Cancer Institute and 188 patients treated at the Royal Marsden Hospital. After adjustment for differences in the distribution of patient prognostic factors, relapse-free survival and overall survival were not significantly different. Of the 1,014 node-positive patients, 540 were treated at the Milan National Cancer Institute, 258 at the Royal Marsden, and 216 at the M. D. Anderson Hospital. Relapse-free survival and overall survival did not significantly differ between Milan patients and those treated at the Royal Marsden Hospital. However, M. D. Anderson Hospital patients did have significantly better relapse-free and overall survival. In each institution, outcome was consistently most dependent on the number of involved axillary lymph nodes and tumor size. Also, similar patterns of survival were observed for each of the institutions. The development of an NHDB can be of value in the identification and evaluation of consistency of prognostic factors, permitting improved comparisons between clinical trials. The development of such a natural history data base (NHDB) provides a reference for assessing the impact of different adjuvant chemotherapy programs, and aids in the design of new protocols.

Abstract
Prognostic factors and treatment were analyzed for 2,578 patients to assess the impact of various forms of adjuvant chemotherapy on the natural history of operable stage II (node-positive) breast cancer. The outcome after surgery alone (or with radiotherapy) was determined in 1,014 patients in the natural history data base (NHDB). Adjuvant chemotherapy consisted of L-phenylalanine mustard (L-PAM; 130 patients); cyclophosphamide, methotrexate, and 5-fluorouracil (CMF; 645 patients); doxorubicin and cyclophosphamide (AC; 241 patients); CMF plus vincristine and prednisone (CMFVP; 263 patients); and 5-fluorouracil plus AC (FAC; 285 patients). L-PAM had minimal effect on relapse-free survival (RFS) compared to the NHDB, but all combination chemotherapy programs significantly improved RFS and survival compared to the NHDB. In women with 1-3 positive nodes, all combination chemotherapy programs produced similar results. In women with 4-9 positive nodes, the FAC regimen appeared to be associated with superior RFS compared to other programs, but all were superior to the NHDB. In women with 10 or more positive nodes, FAC was the only regimen associated with improved RFS. The use of a NHDB and known pretreatment characteristics, such as nodal status and tumor size, permits comparison of patients at similar risk of recurrence of breast cancer who have received adjuvant chemotherapy and provides leads for evaluation in future prospective clinical trials.

Abstract
Previous studies have established CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) as the standard of comparison for treatment programs for patients with advanced stages of aggressive non-Hodgkin's lymphomas. Three sequential CHOP studies conducted by the Southwest Oncology Group (SWOG) showed a complete remission (CR) rate of 53% for 418 patients. This rate did not vary among the three studies. Median age was over 55 years. Relapse-free survival of CRs plateaued at 4 to 5 years. Approximately 21% of all patients in the first study and 33% of all patients in the following two studies are long-term survivors and presumed cured. Survival was clearly a function of patient age. Approximately 45% of all patients under age 55 at the time of treatment are cured by CHOP chemotherapy. To determine the toxicity, CR rate, and patient survival of m-BACOD (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, dexamethasone), ProMACE-CytaBOM (prednisone, methotrexate, doxorubicin, cyclophosphamide, etoposide, cytarabine, bleomycin, vincristine, methotrexate), and MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, bleomycin), SWOG initiated a series of phase II studies. Of 118 eligible patients in the m-BACOD study, the median age of 85 patients treated with the full-dose regimen was 54 years, while the median age of 33 patients who started therapy at reduced doses was 67 years. Fatal toxicity was observed in 6% of patients receiving full doses and 13% of those receiving reduced doses. Life-threatening toxicity occurred in 31% of patients on the full-dose regimen and 34% on the reduced-dose regimen. CR was 65% for full-dose treatment, but 27% for reduced doses.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Retinoids, including isotretinoin, have demonstrated antiproliferative and antineoplastic activity in laboratory and clinical trials. In a phase II trial, 25 patients with extensive mycosis fungoides were evaluated for response to isotretinoin. There was a 44% (11 patients) objective clinical response rate with three clinical complete responses without concomitant evidence of pathologic clearing of the disease. An additional 24% (six patients) showed a minor degree of clinical improvement. The median time to response was two months (range, 0.5 to eight months) and the median response duration was eight months or longer (range, one to 25 months). Chronic toxic reactions consisted primarily of drying of the skin and mucous membranes and resulted in dose reduction in the majority of patients. It is concluded that isotretinoin produces significant clinical benefit to some patients with mycosis fungoides.

Abstract
Immunohistology was used for the detection of Legionella pneumophila serogroup I in necropsy tissue. Study of pneumonic lung from the recent Stafford outbreak has shown that this technique has a high sensitivity. A retrospective postmortem examination showed that L pneumophila serogroup 1 was an unusual cause of pneumonia in Oxfordshire during the study period. L pneumophila serogroup 1 can be successfully subgrouped, using a panel of monoclonal antibodies on formalin fixed paraffin embedded sections. Immunohistological methods have a potentially useful role in the diagnosis of Legionellosis at postmortem examination and in the epidemiological investigation of individual cases and outbreaks.

Abstract
The reticulocyte count, serum ferritin and serum erythropoietin concentrations were measured during the course of pregnancy in 41 women. A decrease in iron stores early in pregnancy was accompanied by a significant rise in the reticulocyte count until the 28th week. Erythropoietin levels did not rise significantly until the 28th week of pregnancy and had fallen to the post-natal level by 40 weeks. The results are consistent with an increase in erythropoietic activity early in pregnancy which did not appear to depend upon increased plasma erythropoietin levels.

Abstract
We compared HLA antigens in 28 patients with obliterative bronchiolitis (16 with rheumatoid arthritis) with those in 150 normal controls, to determine their relationship to drug toxicity and to the pathogenesis of obliterative bronchiolitis (OB). There was a significantly increased prevalence of HLA-B40 in the whole group and in patients with OB and rheumatoid arthritis (RA). There was increased frequency of HLA-A2 and A28 within the whole group and in those with OB alone. HLA-A3 and B5 were completely absent in our patients. Of those antigens most frequently associated with RA, DR4 was significantly more prevalent in patients with OB, with or without RA, but DR1 occurred more frequently only in those with RA-associated OB. Increased prevalence of DR4 may indicate an association between the pathogenesis of both OB and RA and the HLA-DR locus. Although D-penicillamine has been implicated in the pathogenesis of OB our patients did not show an increase in those antigens associated with other gold/penicillamine toxicity (i.e. DR2/3), suggesting that they may constitute a distinct group.

Abstract
To study the influence of chronologic age on treatment outcome in patients with advanced, diffuse large-cell (histiocytic) lymphoma (DHL), we reviewed the results of two recent Southwest Oncology Group (SWOG) clinical trials. From 1974 to 1982, members entered 307 eligible patients treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without bleomycin, and CHOP with or without immunotherapy using BCG, levamisole, or both. Complete response (CR) rates declined progressively with advancing age: 65% in those under 40, 60% in the 40 to 54 age group, 55% in the 55 to 64 age group, and 37% in those 65 and older (P = .001). Likewise, survival decreased significantly in older patients: medians were 101 +, 52, 34, and 16 months, respectively (P less than .001). Treatment guidelines included an initial dose reduction of 50% for patients aged 65 or older and for younger patients with bone marrow compromise. Despite protocol specifications, 23 of 81 patients aged 65 or older received initial full-dose therapy. When these patients were compared with younger patients on whom full-dose chemotherapy was started, survival curves, but not CR rates, were still significantly different. There were no significant differences in duration of CR or frequency of treatment complications. These data suggest that older age is associated with a worse prognosis in advanced DHL. Moreover, the initial dose reduction for patients aged 65 or older may have contributed to their inferior outcomes.

Abstract
We tested the combination of cisplatin, amsacrine, and mitoguazone as salvage treatment for patients with advanced unfavorable non-Hodgkin's lymphomas. An objective response rate of 43% was noted in 30 evaluable patients, but all responses were partial and the median duration of response was only 2 months. Toxicity included life-threatening and fatal leukopenia and severe gastrointestinal intolerance. We conclude that this combination chemotherapy regimen is not a valuable salvage treatment for patients with non-Hodgkin's lymphoma.

Abstract
A phase II trial of esorubicin (4' deoxydoxorubicin) was performed in patients with cancers of the breast, colon, kidney, lung and melanoma. Two partial responses were observed out of 16 patients with breast cancer treated with esorubicin. No objective responses (complete or partial) were seen in patients with colon cancer (18 patients), lung cancer (12 patients), renal cell cancer (12 patients) and melanoma (18 patients). Myelo-suppression was the most significant toxicity encountered with granulocytopenia (neutrophils less than 1,000) observed in 38% of patients. As discussed, we feel that further investigation of esorubicin in anthracycline-sensitive tumors is warranted.

Abstract
Forty evaluable patients with malignant lymphoma (ML) were treated with bisantrene at a dose of 260 mg/m2 every 3 weeks (18 patients) or 208 mg/m2 every 3 weeks (22 patients). The initial dose rate was determined on the basis of expected myelosuppression. Patients were heavily pretreated and had advanced disease (92% had stage IV). The overall response rate was 10% and included 1 partial response (PR) in 17 patients with Hodgkin's disease (HD), 1 PR and 1 complete response (CR) in 5 patients with favorable histology in non-Hodgkin's lymphoma (NHL), and 1 PR in 18 patients with unfavorable histology in NHL. Neutropenia (WBC less than or equal to 3000 cells/microliter) was the most common toxicity, occurring in 50% of patients. Phlebitis was a common side effect in patients treated with bisantrene administered by way of peripheral veins. Bisantrene has limited activity in heavily pretreated patients with HD or unfavorable histology in NHL. The role of bisantrene for treatment of NHL with favorable histology or for treatment at an earlier point in the natural history of ML is unknown.

Abstract
This study compared the pre-treatment characteristics of participants in three weight reduction programmes who either completed treatment or dropped out. The three programmes each lasted for 16 weeks, selected subjects on the same criteria, and offered the same dietary advice. The first two programmes were run by the same psychologist in the same community setting. In each study a different set of characteristics significantly separated completers from dropouts, and discriminant function analysis assessed how well this separation was achieved. The discriminant function from the first study correctly identified 75% of the subjects on which it was based. When applied to the second study it correctly identified 64% of subjects, showing limited generalisability. There were also significant differences between early dropouts and late drop-outs, but the nature of these varied between studies. In discussing the implications of these results it was argued that further research might more fruitfully focus on psychological processes involved in drop-out rather than continue to search for correlates of drop-out.

Abstract
Because "the standard" chemotherapy for advanced gastric adenocarcinoma, the FAM combination of 5-fluorouracil, adriamycin, and mitomycin, is only minimally effective, there is a clear need for other choices. Therefore, the Southwest Oncology Group tested the new adriamycin analog, bisantrene, hoping that it might be more effective than the "parent drug." Twenty-six patients with gastric adenocarcinoma were treated on a program of every-3-week 2-hour bisantrene infusions. The starting dose was 260 mg/m2 (208 if poor risk), with subsequent doses based on prior toxicity. The regimen caused sufficient toxicity (especially local phlebitis with pain and swelling) to assure an adequate test. One person (3.8% of eligible patients) experienced a clinically useful 3-month response. He had previously had progressive disease on FAM. Nevertheless, we conclude that bisantrene is not an addition to the small list of drugs useful in the management of gastric adenocarcinoma.

Abstract
Between 1977 and 1983 the Southwest Oncology Group (SWOG) evaluated chemotherapy alone (cyclophosphamide, doxorubicin, vincristine, prednisone; CHOP) or chemoimmunotherapy (CHOP-levamisole or CHOP-levamisole-BCG) in a randomized prospective clinical trial involving 715 eligible patients with all types of malignant lymphoma (ML). Of 281 evaluable patients with favorable histologic types of ML, 171 (61%) achieved complete remission (CR) and there was no difference in CR rate, CR duration, or survival according to the type of initial treatment. Of 388 evaluable patients with unfavorable histologic types of ML, 194 (50%) achieved CR. Levamisole appeared to adversely affect CR rates in nodular mixed and nodular large-cell lymphoma and CR duration in patients with unfavorable histology ML. Chemoimmunotherapy with levamisole or levamisole-BCG offers no advantage in terms of CR rates, CR duration, or survival compared to CHOP chemotherapy alone, and levamisole may have had an adverse impact on outcome in certain subtypes of ML.

Abstract
Combined chemohormonal therapy is an attractive therapeutic strategy for the treatment of Stage IV breast cancer. Between 1977 and 1979, the authors evaluated a new chemohormonal therapy program in 63 evaluable women with advanced breast cancer who previously had not received cytotoxic chemotherapy or tamoxifen. The chemohormonal therapy consisted of 21- to 28-day cycles of tamoxifen (10 mg orally twice daily), Adriamycin (doxorubicin) (40 mg/m2 intravenously on day 1) and cyclophosphamide (200 mg/m2 orally on days 3-6) (TAC). Objective responses were observed in 82% of the patients (22% complete response, 60% partial response). With a median follow-up of 104 weeks (2 years), the median relapse-free survival for the 52 responding patients was 80 weeks. The median survival for the entire group of 63 patients was 118 weeks. Eleven pretreatment patient characteristics were evaluated via univariate and multivariate analysis to determine their effect on response and survival. Prognostic factors with a significant association with longer survivals were as follows: a lack of soft tissue involvement, a lack of pleural involvement, and a long disease-free interval (DFI). Estrogen receptor (ER)-unknown patients, being composed primarily of postmenopausal patients with a long DFI and single-organ involvement (primarily bone), comprised 62% of the patient population and achieved a survival similar to the smaller number of ER-positive patients and was superior to the survival of ER-negative patients. Toxicities were recorded on all patients and overall the treatment was well tolerated. Combined chemohormonal therapy with TAC resulted in a high objective response rate and a long median survival. This study would support additional trials of chemohormonal therapy in patients with ER-positive tumors or in those whose tumors are likely to be ER-positive (e.g., postmenopausal patients with long DFIs).

Abstract
Healthy adult volunteers were inoculated intranasally with human parvovirus obtained from an asymptomatic blood donor. One week after inoculation, intense viremia was observed in seronegative volunteers, accompanied by a mild illness with pyrexia, malaise, myalgia, itching, and excretion of virus from the respiratory tract. In the following week hematologic studies revealed reticulocytopenia with an associated slight drop in hemoglobin concentration, lymphopenia, neutropenia, and a drop in platelet counts. At 17-18 days after inoculation a second-phase illness with rash and arthralgia lasting three to four days occurred in three of four infected volunteers. This study confirms the etiologic role of human parvovirus in erythematous rash illness, with the second-phase illness being consistent with adult cases of erythema infectiosum. Moreover, the hematologic changes associated with infection support the hypothesis that the same virus is responsible for the temporary arrest of erythropoiesis that leads to aplastic crisis in persons with chronic hemolytic anemia.

Abstract
In the spring of 1980, an epidemic of an illness that resembled erythema infectiosum occurred in Manitoba, Canada. We initiated prospective epidemiologic, clinical, and microbiologic studies of this illness among elementary-school children and their families. Initial microbiologic studies failed to identify the cause of the exanthem. After a similar illness associated with serologic evidence of human parvovirus infection occurred in London, stored specimens of 12 patients with exanthem were investigated for parvovirus infection. Eleven patients had parvovirus-specific IgM antibody, as did two family contacts and a teacher with nonexanthematous illnesses, and two asymptomatic family members. None of 28 children with measles or rubella had serologic evidence of recent parvovirus infection. Human parvovirus was detected by DNA hybridization and immune electron microscopy in the serum of one patient who later had a rash and in one unaffected family contact. Parvovirus DNA was also detected in the pharyngeal specimen of the teacher who was ill but did not have a rash. We conclude that human parvovirus infection can be asymptomatic or cause a variety of clinical manifestations, including nonexanthematous illness and an illness resembling erythema infectiosum.
