Polymyositis as a cause of total gut failure.

BACKGROUND: Gastrointestinal manifestations are seen in systemic sclerosis and mixed connective tissue disorders but are rare in pure polymyositis. CASE REPORT: A 44 year old woman with polymyositis who developed total gut failure requiring treatment with total parenteral nutrition is described. RESULTS: The patient's polymyositis is now fully controlled biochemically, but her gastrointestinal symptoms persist.

Tumor regressions observed in patients with metastatic melanoma treated with an antigenic peptide encoded by gene MAGE-3 and presented by HLA-A1.

Thirty-nine tumor-bearing patients with metastatic melanoma were treated with 3 subcutaneous injections of the MAGE-3.A1 peptide at monthly intervals. No significant toxicity was observed. Of the 25 patients who received the complete treatment, 7 displayed significant tumor regressions. All but one of these regressions involved cutaneous metastases. Three regressions were complete and 2 of these led to a disease-free state, which persisted for more than 2 years after the beginning of treatment. No evidence for a cytolytic T lymphocyte (CTL) response was found in the blood of the 4 patients who were analyzed, including 2 who displayed complete tumor regression. Our results suggest that injection of the MAGE-3.A1 peptide induced tumor regression in a significant number of the patients, even though no massive CTL response was produced.

Treatment of invasive thymoma with single-agent ifosfamide.

PURPOSE: To evaluate single-agent ifosfamide in the treatment of invasive thymoma. PATIENTS AND METHODS: Fifteen patients (eight male and seven female) with histologically confirmed invasive thymoma were treated. The median age was 48 years (range, 23 to 76 years). Four patients had stage III disease, seven patients had stage IVa disease, and four patients had stage IVb disease. The most common histologic type was lymphoepithelial. Seven patients had received prior treatment, including one patient who received chemotherapy. Ifosfamide 1.5 g/m(2) was given on days 1 to 5, with mesna as a uroprotector. RESULTS: Thirteen patients were assessable for response. Five complete responses (38.5%; 95% confidence interval [CI], 17.7% to 64.5%) and one partial response (7.7%; 95% CI, 1.4% to 33.3%) were seen. The median duration of complete response was 66+ months (range, 25 to 87 months), and the estimated survival rate 5 years after ifosfamide treatment was 57% (SE, 32% to 79%). The most frequent toxicities were nausea, vomiting, and leucopenia, but these were well tolerated. CONCLUSION: Single-agent ifosfamide possesses significant activity against invasive thymoma and is comparable to currently used combination regimens. The inclusion of ifosfamide in combination therapy, particularly in place of cyclophosphamide in regimens such as cisplatin, doxorubicin, and cyclophosphamide, needs to be evaluated.

CAMPATH-1H monoclonal antibody in therapy for previously treated low-grade non-Hodgkin's lymphomas: a phase II multicenter study. European Study Group of CAMPATH-1H Treatment in Low-Grade Non-Hodgkin's Lymphoma.

PURPOSE: CAMPATH-1H is a human immunoglobulin G1 (IgG1) anti-CD52 monoclonal antibody (MAb) that binds to nearly all B-cell and T-cell lymphomas. We report here the results of a multicenter phase II trial of CAMPATH-1H in patients with advanced, low-grade non-Hodgkin's lymphoma (NHL) who were previously treated with chemotherapy. PATIENTS AND METHODS: Fifty patients who had relapsed (n=25) after or were resistant (n = 25) to chemotherapy were treated with CAMPATH-1H 30 mg administered as a 2-hour intravenous (i.v.) infusion three times weekly for a maximum period of 12 weeks. RESULTS: Six patients (14%) with B-cell lymphomas achieved a partial remission (PR). Patients with mycosis fungoides appeared to respond more frequently (50%; four of eight patients, which included two complete remissions [CRs]). Lymphoma cells were rapidly eliminated from blood in 16 of 17 patients (94%). CR in the bone marrow was obtained in 32% of the patients. Lymphoma skin lesions disappeared completely in four of 10 patients and partial regression was obtained in three patients. Lymphadenopathy and splenomegaly were normalized in only 5% and 15% of patients, respectively. Lymphopenia (< 0.5 x 10(9)/L) occurred in all patients. World Health Organization (WHO) grade IV neutropenia occurred in 14 patients (28%). Opportunistic infections were diagnosed in seven patients and nine patients had bacterial septicemia. Death related to infectious complications occurred in three patients. CONCLUSION: CAMPATH-1H had a significant but limited activity in patients with advanced, heavily pretreated NHL. The most pronounced effects were noted in the blood and bone marrow and in patients with mycosis fungoides. The risk for serious infectious complications needs to be considered for severely ill patients who are evaluated for CAMPATH-1H treatment.

Intra-articular therapy in osteoarthritis.

Although intra-articular therapy is widely used in the treatment of osteoarthritis (OA), those controlled clinical trials which include placebo groups suggest that there is little to be gained over joint aspiration alone, or even over a simple needle prick. Glucocorticoids may however offer a small additional symptom benefit over one or two weeks. Viscosupplementation may offer a slightly longer benefit. Intra-articular radiotherapy probably confers no benefit. Serious adverse effects are rare but local effects may occur in up to 10% of patients treated with viscosupplements. Future research should always include a placebo group in clinical studies, should clarify the possible benefits of viscosupplementation and should include in vitro work to consider the biological basis for possible actions of intra-articular therapy.

Standardising joint assessment in rheumatoid arthritis.

Evaluating joint involvement in rheumatoid arthritis in a key clinical assessment. We investigated the extent of variation in measurement of joint swelling and tenderness and evaluated the impact of training to standardise methods. Eight observers (medical and nursing staff) examined eight rheumatoid patients for joint swelling and tenderness before and after training in clinical methods. The EULAR handbook for joint evaluation was used for training and assessments were based on the 28 joint count. There was extensive variability in both numbers of swollen and tender joints. Coefficients of variation for articular indices recorded by the 8 observers in individual patients were often high (up to a maximum of 204%), indicating considerable differences between observers. Training had an impact on the assessment of the numbers of swollen joints which increased by a mean of 32% (P < 0.05) and the number of tender joints which increased by 41% (p < 0.01). Training had only a limited impact on the variation among observers in determining the number of swollen and number of tender joints. After training, the mean coefficients of variation were still 59% for swollen joints and 65% for tender joints. These results highlight the extent of variation in clinical assessment of rheumatoid arthritis and show the advantages of training. It leads to increased sensitivity of measurement. Standardisation appears essential for clinical studies.

Doxorubicin versus CYVADIC versus doxorubicin plus ifosfamide in first-line treatment of advanced soft tissue sarcomas: a randomized study of the European Organization for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group.

PURPOSE: The aim of this trial was to compare the activity and toxicity of single-agent doxorubicin with that of two multidrug regimens in the treatment of patients with adult advanced soft tissue sarcomas. PATIENTS AND METHODS: This was a prospective randomized phase III trial performed by 35 cancer centers within the Soft Tissue and Bone Sarcoma Group of the European Organization for Research and Treatment of Cancer (EORTC). Six hundred sixty-three eligible patients were randomly allocated to receive either doxorubicin 75 mg/m2 (arm A), cyclophosphamide, vincristine, doxorubicin, and dacarbazine (CYVADIC) (arm B), or ifosfamide 5 g/m2 plus doxorubicin 50 mg/m2 (arm C). RESULTS: The overall response rate was 24% (95% confidence interval, 20.7% to 27.3%) among eligible patients and 26% among assessable patients. No statistically significant difference was detected among the three study arms in terms of response rate (arm A, 23.3%; arm B, 28.4%; and arm C, 28.1%), remission duration (median, 46 weeks on arm A, 48 weeks on arm B, and 44 weeks on arm C), or overall survival (median, 52 weeks on arm A, 51 weeks on arm B, and 55 weeks on arm C). The degree of myelosuppression was significantly greater for the combination of ifosfamide and doxorubicin than for the other two regimens. Cardiotoxicity was also more frequent in this arm, but other toxicities were similar. CONCLUSION: In advanced soft tissue sarcomas of adults, single-agent doxorubicin is still the standard chemotherapy against which more intensive or new drug treatments should be compared. Combination chemotherapy cannot be recommended outside a controlled clinical trial with the exclusion of some subsets of sarcoma patients for whom significant tumor volume reduction may be an important end point of a chemotherapy regimen.

Carboplatin-based combination chemotherapy for advanced carcinoma of the cervix.

A combination of carboplatin, vincristine, methotrexate and bleomycin (COMB) was given to 29 patients with locally advanced, metastatic or recurrent cervical carcinoma. A total of 85 cycles of chemotherapy were given, with half of the patients receiving greater than 3 cycles. Both the response rate (32.1%) and the median duration of response (30 weeks) were relatively disappointing. Renal toxicity was minimal, but one-third of our patients experienced severe (WHO grades 3 and 4) nausea and vomiting. This combination showed little advantage over carboplatin used as a single agent.

Results of treatment of non seminomatous germ cell tumours; 122 consecutive cases in the West of Scotland, 1981-1985.

Between January 1981 and December 1985, 122 patients with non-seminomatous germ cell tumours (NSGT) were seen at a regional referral centre. Of these, a total of 98 patients received chemotherapy for metastatic disease. Treatment was given within collaborative EORTC Urology group studies, all of which involved cis-platin-containing schedules. Ninety patients had tumours of testicular origin, and their 2 year actuarial survival rate is 91%; 8 had tumours of extragonadal origin and their 2 year actuarial survival is 25%. Patients with testicular tumours were subdivided by volume of metastatic disease using the recommendations of the Testicular Cancer Subgroup of the MRC Urological Cancer Working Party and survival was significantly worse in the group with very large volume metastatic disease (VLVM, 57%) compared with the groups with large volume metastases (LVM, 100%) and small volume metastases (SVM, 98%). There were 31 patients with Stage I disease at presentation; of these 6 were treated by prophylactic abdominal radiotherapy and 25 were managed by a policy of surveillance only. Seven of these Stage I patients (23%) relapsed with metastatic disease (median 8 months); all have been successfully treated with chemotherapy. These data confirm that the majority of patients now presenting with metastatic NSGCT are curable with chemotherapy, but that a small proportion with very large volume metastases or extragonadal tumours require alternative chemotherapy schedules.

VAC (vincristine, adriamycin, cyclophosphamide) chemotherapy for metastatic carcinoma from an unknown primary site.

Twenty patients presenting with metastatic carcinoma from an unknown primary site were studied. All patients were treated with a triple chemotherapy regimen of vincristine, adriamycin and cyclophosphamide repeated at three-week intervals. The response rate was 50%, and the four patients achieving complete response are alive and disease-free at 13, 16, 36 and 39 months. Toxicity was minimal and the majority of patients' performance status improved with the chemotherapy. VAC chemotherapy is indicated for patients with metastases, particularly of soft tissues originating from a carcinoma from an unknown primary site.

Glycoprotein hormone alpha-subunit secretion in patients with pituitary adenomas: influence of TRH, LRH and bromocriptine.

Twelve patients with pituitary adenomas and increased serum concentration of the glycoprotein hormone alpha-subunit were studied. Eight patients were acromegalic and one had a FSH producing tumour. The adenomas in 9 patients had undergone subtotal operative removal and/or external irradiation but no patient was studied within 3 months of these treatments. Many of the acromegalic patients, with moderately elevated alpha-levels, showed marked increases in alpha-concentration after TRH and/or LRH, compared with controls. The non-acromegalic patients, with the highest alpha-levels, showed poor responses to releasing hormones. These results suggest that excessive alpha-subunit secretion in acromegalic patients is often under hypothalamic control whereas in non-acromegalic patients it is often autonomous. Seven patients, 4 with acromegaly, were then given oral bromocriptine, 5 mg over 3 h. There was a significant fall in log mean alpha-level at 4 and 5 h (P less than 0.02). Six patients took bromocriptine for 1--2 months. Log mean alpha-concentration was significantly reduced at the end of treatment (P less than 0.02) and then recovered to basal levels after stopping treatment for one week. alpha-Subunit hypersecretion in some patients with pituitary adenomas is therefore modulated by dopaminergic control mechanisms.
