A young, diabetic woman suffering from fainting spells, vomiting, and diarrhea is described. Extensive investigations showed total cardiac denervation, orthostatic hypotension, and disturbances in the the pupillary and sudomotor functions, as well as impairment of glucagon secretion during hypoglycemia. These disturbances were found to be caused by autonomic neuropathy. No signs of peripheral neuropathy could be detected. To the best of our knowledge this is the second case of total cardiac denervation due to diabetic neuropathy described in the literature.

A total of 32 previously untreated patients aged 65 years or older with non-Hodgkin's lymphoma (NHL) were treated with VEPA (vincristine, cyclophosphamide, prednisolone and doxorubicin) or ML-Y1 (doxorubicin, cyclophosphamide, vincristine, methotrexate, bleomycin, procarbazizin and prednisolone). The median age of the patients was 70 years (range 65-77), 19 males and 13 females. The outcome of 16 patients with VEPA and 16 patients with ML-Y1 was retrospectively evaluated. There were no significant differences in response or survival between VEPA and ML-Y1, complete remission rates were 37.5% vs. 31.3% and duration of 50% survival were 20 months and 13 months, respectively. Major side effects of both regimens were myelosuppression, hair loss, nausea, vomiting and peripheral neuropathy. There was no increased toxicity in ML-Y1 but this regimen seemed like VEPA, to be insufficient for NHL in elderly patients. A new intensive regimen should be designed to treat NHL in the elderly patients.

This study investigated the therapeutic effect of single-agent i.v. weekly Navelbine (vinorelbine), a semisynthetic vinca alkaloid, in women who had received no prior treatment for locally advanced or metastatic breast cancer. Of 68 patients entered into the study, 63 were adequate inclusions, assessable for toxicity and response by WHO criteria; the 5 patients who were not evaluated were excluded from analysis because they were found not to meet the eligibility criteria of the study. Navelbine was given as a weekly 30 mg/m2 short i.v. (20 minutes) infusion; treatment was continued until disease progression. The overall response rate was 44% (complete response 8%, partial response 36%). The response rate according to target was lymph nodes, 62.9%; liver, 50.0%; lung, 50.0%; skin, 37.5%; and primary tumor, 30.8%. The median duration of response was 17.9 weeks (range: 7-52 weeks). The median time to treatment failure was 12.9 weeks, and the median survival was 50.3 weeks. The 63 eligible patients received 501 cycles. The mean dose intensity was 76%. At least one episode of WHO grade 3/4 granulocytopenia was seen in 46% of the patients (13.6% of cycles). Significant nausea/vomiting was seen in only 5% of patients corresponding to 1% of cycles. Only 5% of patients developed WHO grade 3-4 constipation and grade 3 peripheral neuropathy was observed in 1.6% of patients. Alopecia was rare (6.3% of patients), and other side effects were uncommon. This study confirms that Navelbine has major single-agent antitumor activity as frontline therapy in advanced breast cancer. Given its excellent tolerance profile and low morbidity, it should be recommended for inclusion in first-line combination chemotherapy regimens.

The combination of 5-fluorouracil (5-FU) and folinic acid (FA) has demonstrated activity in colorectal cancer (CC). Cisplatin is reported to have synergistic activity with 5-FU. We examined the combination FA + 5-FU + cisplatin in patients who had previously received chemotherapy with FA + 5-FU and relapsed. Two months after the last dose of FA + 5-FU and documentation of relapse, patients continued with the regimen consisting of cisplatin 20 mg/m2 in 15 min i.v. infusion followed by FA 500 mg/m2 in 1 h i.v. infusion, in the middle of which 5-FU 500 mg/m2 i.v. bolus was administered, with adequate post-hydration. This was repeated weekly for 4 weeks followed by a 2 week rest, for a maximum of six cycles. A total of 30 patients with CC that had relapsed to the combination of FA + 5-FU were treated; 23 had previous surgery and none had radiotherapy. Local recurrence was found in eight patients, metastases in the liver in 21, in lymph nodes in six, lung six and peritoneal metastases in seven. Seven patients responded partially. Toxicity requiring dose reduction or discontinuation of treatment included neutropenia 42% (grade 3:7%), mucositis 28% (grade 1:2), diarrhea 63% (Grade 3:10%), nausea-vomiting 55% (Grade 3:10%), increased creatinine value in three patients and peripheral neuropathy in two patients. We conclude that evaluation of this regimen shows substantial toxicity, with satisfactory response as a second line chemotherapy in these heavily pretreated patients.

Combination chemotherapy with 5-FU and CDDP was given to two patients with far advanced gastric cancer. One patient was associated with metastases of lung, liver, pancreas and Virchow and periaortic lymph nodes, and the other was associated with metastases of periaortic lymph nodes and malignant ascitis. The regimen consisted of 5-FU 1,000 mg/m2 (day 1-5, continuous infusion) and CDDP 100 mg/m2 (day 3, 1 hr drip infusion). The interval was from the 6th to the 21st day. The response to chemotherapy showed shrinking of primary gastric lesions and metastases of liver, pancreas and periaortic lymph nodes, and disappearance of Virchow lymph nodes and malignant ascitis. Adverse reactions were thrombocytopenia (Grade 4), leukocytopenia (Grade 3), stomatitis (Grade 1, 3), vomiting (Grade 1, 2) and peripheral neuropathy (Grade 3). This therapy is thought to be effective against far advanced gastric cancer.

N-Debenzoyl-N-tert-butoxycarbonyl-10-deacytyl taxol (Taxotere, RP 56976) is a semisynthetic analogue of taxol, prepared from a noncytotoxic precursor extracted from the needles of the European yew tree (Taxus baccata L.). It has a broad spectrum of antitumor activity against a variety of transplantable tumors in mice. In vitro cytotoxicity assays suggest that it is 2-5-fold more potent than taxol. In this phase I study Taxotere was administered by 24 h i.v. infusion at 3-week intervals. Thirty patients with solid tumors refractory to conventional therapy were treated; 70 courses of Taxotere were administered at doses ranging from 10 to 90 mg/m2. Grade 4 neutropenia and grade 3 mucositis were dose limiting but reversible at 90 mg/m2. The pattern and grade of toxicity at this dose were similar in 3 heavily pretreated patients compared with 7 patients who had received a maximum of one previous chemotherapy regimen. Alopecia occurred at 55 mg/m2 and above. Other mild toxicities included phlebitis, diarrhea, emesis, and sensory peripheral neuropathy, but these were neither dose-limiting nor clearly dose-related. One patient treated at 70 mg/m2 had an anaphylactoid reaction following the second dose of Taxotere. No cardiovascular toxicity was observed. No partial or complete responses were documented. Plasma concentrations of Taxotere were determined by high-performance liquid chromatography, and end-of-fusion levels at the maximum tolerated dose exceeded drug concentrations which are cytotoxic in vitro. The maximum tolerated dose for Taxotere administered as a 24-h infusion is 90 mg/m2.

We studied the clinical, biochemical, and genetic features of eight patients with the autosomal recessive mitochondrial syndrome mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). MNGIE is clinically characterized by ophthalmoparesis, peripheral neuropathy, leukoencephalopathy, gastrointestinal symptoms (recurrent nausea, vomiting, or diarrhea) with intestinal dysmotility, and histologically abnormal mitochondria in muscle. Brain MRI scans were consistent with leukodystrophy in seven patients examined. Nerve conduction and EMG studies were compatible with a sensorimotor neuropathy; quantitative EMG of two patients suggested a myogenic process. Muscle mitochondrial enzyme analysis revealed a partial defect of cytochrome c oxidase activity in five patients; three had additional respiratory chain enzyme defects. Two patients had isolated complex I defects, and one had normal respiratory chain function. Southern blot analysis revealed multiple deletions of mitochondrial DNA in four of eight patients.

Thirty patients with previously untreated, inoperable non-small cell lung cancer (NSCLC) were treated with cisplatin, etoposide and vincristine. Among twenty-nine evaluable patients, eight patients achieved partial response and the overall response rate was 28%. No patient achieved a complete response. The median survival time was 51 weeks. Myelosuppression was the dose-limiting toxicity. Four patients had a leukocyte nadir of less than 1000/mm3, and one died from severe myelosuppression and sepsis. The other toxicities were nausea/vomiting, peripheral neuropathy, and alopecia. We conclude that cisplatin, etoposide, and vincristine combination chemotherapy offers moderate activity for inoperable non-small cell lung cancer.

Cisplatin is an active cytostatic that became successful in the treatment of several types of solid tumours after its nephrotoxic potential was controlled by hydration and diuresis. Thiol compounds were tested to reduce further cisplatin-induced nephrotoxicity. Thiosulphate is rapidly excreted by the kidneys and protects against cisplatin-induced nephrotoxicity by inactivating reactive platinum species in the kidney. Due to inactivation of cisplatin in the circulation, thiosulphate also interferes with its antitumour activity. Therefore, it is mainly used in two-route schedules, whereby cisplatin is delivered locally to the tumour (i.p. or i.a.) while systemic (i.v.) thiosulphate protects the kidneys. Diethyldithiocarbamate was shown to protect against cisplatin-induced nephrotoxicity in several animal models by reversing cellular damage. However, in the clinic it has been less successful, partly due to its central nervous system toxicity. The endogenous thiol compounds glutathione and metallothionein have been shown to reduce cisplatin-induced toxicity both in animal models and in clinical trials. However, the results are rather preliminary and a reduction in therapeutic efficacy may be expected, for both glutathione and metallothionein have been reported to be involved in platinum resistance. The thioether methionine has been shown to reduce cisplatin-induced nephrotoxicity in animal models but it has not yet been tested in the clinic. Cisplatin-induced acute emesis can be sufficiently controlled with a new class of 5-hydroxytryptamine-3 (5HT3)-receptor blockers, but delayed emesis remains a problem. High-dose cisplatin regimens with protection of the kidneys induces ototoxicity, peripheral neuropathy and myelotoxicity, which become dose-limiting. Neurotoxicity was partly reversed by the neurogenerative agent ORG2766, but this agent does not reduce other cisplatin-induced toxicities. Therefore, an agent capable of protecting multiple non-tumour tissues is needed. Carboplatin is a second-generation analogue of cisplatin with less nephro-, neuro- and ototoxicity. Carboplatin is at least as active as cisplatin at its maximum tolerated dose, which is defined by its myelotoxicity. Protection from carboplatin-induced myelotoxicity may be controlled by autologous bone marrow transplantation and/or hematopoietic growth factor infusions. High-dose carboplatin schedules may cause nephrotoxicity, neurotoxicity and ototoxicity. Again, the protection of multiple non-tumour tissues is needed. WR2721 appears to be such a modulating agent capable of protecting multiple non-tumour tissues. It was shown to be preferentially metabolized and taken up as the thiol metabolite WR1065 by non-tumour tissues as compared with (hypoxic) solid tumours. It was shown to protect mice from cisplatin-induced nephrotoxicity and from cisplatin- and carboplatin-induced myelotoxicity without interfering with the antitumour activity.(ABSTRACT TRUNCATED AT 400 WORDS)

Defects in mitochondrial beta-oxidation may result in severe metabolic crisis after metabolic stress. The combination of hypoketotic hypoglycaemia and concurrent collapse of mitochondrial metabolic function may be very similar to that in Reye syndrome. Chronic effects on cardiac and skeletal muscle may be seen in some patients with defective long-chain fatty acid oxidation. Less common symptoms include peripheral neuropathy, pigmentary retinopathy, and failure to thrive with recurrent diarrhoea or vomiting. Collectively, such disorders are relatively common and their association with sudden infant death leads to a considerable demand for laboratory investigation. Currently the laboratory methods available are not capable of dealing with this demand in a rational and cost-effective manner and it is necessary to have careful clinically- and pathologically-based selection procedures if a useful service is to result.
