A 33 year-old man with undiagnosed neuropathy showing mental retardation and involuntary movements has been nourished for a long period by total parenteral nutrition (TPN) because of frequent vomiting and repeated aspiration pneumonitis. After ten months' TPN, macrocytic anemia and neutropenia developed and iron preparation was administered without hematological improvement. Bone marrow examination revealed normocellular marrow without features of megaloblastosis and dysplasia. In some erythroblasts and immature myeloid cells, vacuoles were observed and mature granulocytes were reduced in the bone marrow. Both serum copper and ceruloplasmin were very low (12 micrograms/dl and 7mg/dl, respectively). Thus, oral administration of copper sulfate resulted in marked increase of reticulocytes and subsequent improvement of anemia and neutropenia within two months. Copper deficiency is a rare condition, but during an unusual nutrition such as TNP, hematological abnormality due to copper deficiency must be noticed to occur.

Carboxyamido-triazole (CAI) is a synthetic inhibitor of non-excitable calcium channels that reversibly inhibits angiogenesis, tumor cell proliferation, and metastatic potential. Inhibition of calcium influx and calcium-dependent events is a potential common mechanism underlying these effects of CAI. The cytostatic and antiangiogenic properties of CAI led to its development for clinical investigation. In a Phase I clinical trial open to patients with refractory solid tumors, 49 patients received p.o. administered CAI daily or every other day. Two oral formulations, PEG-400 CAI solution and a gelatin capsule containing CAI in PEG-400, were tested. All administered dosages of CAI yielded plasma concentration at or above the range demonstrated to be effective in inhibiting signaling and cancer progression in vitro and in preclinical models (1 microgram/ml, 2.3 microM). Toxicity of p.o. administered CAI most commonly consisted of dose-related grade 1-2 nausea, vomiting, and occasional anorexia. CAI administration at bedtime ameliorated gastrointestinal complaints in many patients; others required addition of simple antiemetic regimens, usually consisting of metoclopropamide or prochlorperazine. Gastrointestinal complaints were the cause for compliance-limiting toxicity at 175 mg/m2/day of the liquid formulation and 125 mg/m2/day of the gelatin capsule formation. Reversible and rare sensory axonal neuropathy (grade 3, 1 patient) and neutropenia (grade 4, 1 patient) were dose-limiting toxicities observed at the 330 mg/m2 every-other-day liquid CAI dose level. No evidence of cumulative end organ damage or central nervous system injury was observed. Disease stabilization and improvement in performance status was observed. Disease stabilization and improvement in performance status was observed in 49% of evaluable patients who had disease progression before CAI. Disease stabilization and associated improvement in performance status was seen in patients with renal cell carcinoma (7 months), pancreaticobiliary carcinomas (3, 5, and 5 months), melanoma (7 months), ovarian cancer (7 months), and non-small cell lung cancer (3 months). The recommended Phase II doses from this trial are 150 mg/m2/day in the liquid formation and 100 mg/m2/day in the gelatin capsule formation.

A cross-sectional study was designed to identify a relationship between the presence of symptoms usually related to nervous system involvement as well as other chronic complications of diabetes with three objectively defined degrees of autonomic neuropathy (AN). Symptoms usually related to peripheral sensitive neuropathy and AN were assessed using a questionnaire applied to 132 diabetics (38 IDDM and 94 NIDDM), 65 without and 67 with AN. AN was classified as follows according to 5 cardiovascular autonomic tests described by Ewing: 1) early involvement-1 abnormal test (N = 27); 2) definite involvement-2 or 3 abnormal tests (N = 26); 3) severe involvement-4 or 5 abnormal tests (N = 14). A statistically significant association was observed between degree of autonomic involvement and the presence of the following symptoms: dizziness on standing, dysphagia, vomiting, diarrhea, fecal incontinence, gustatory sweating, urinary retention, numbness and hyperesthesia of the feet or legs. Constipation and cystitis were not significantly related to cardiovascular AN. Only 3% of the patients without neuropathy and with early involvement had four or more than four of the symptoms. The prevalence of proliferative retinopathy and nephropathy was increased among patients with more severe degrees of AN. For IDDM patients there was a positive correlation between the degree of cardiovascular AN and the duration of diabetes. We conclude that: 1) severe cardiovascular AN is usually related to 4 or more of the evaluated symptoms and those patients usually have the other complications of diabetes; 2) severe AN could be a risk factor or an indicator of the same underlying process that determines the beginning of proliferative retinopathy and/or nephropathy.

Combination chemotherapy with anti-proliferative agents is often used in patients with advanced non-small cell lung cancer (NSCLC) in good performance status. The mitomycin C, vinblastine and cisplatin (MVP) regimen has been the Eastern Cooperative Oncology Group (ECOG) standard for several years because of high response rates in spite of significant toxicity. In a phase II study, we observed 55 consecutive patients treated with MVP chemotherapy using the same dosage, schedule, and precautions as used by the ECOG group. The dose intensity reached for each drug was 85% of the projected dose. Fifty-one patients were assessable for response and toxicity, while all subjects were evaluable for survival. There was no complete remissions, 8 partial (15%), 34 stable (66%) and 9 progressive (17%) in patients. The median survival rate was 34 weeks (95% confidence interval 28-37 weeks). There were no treatment-related deaths and no grade 4 toxicity. Alopecia and emesis were the most significant adverse effects. Haematological toxicity was minimal. Other side-effects, such as neuropathy and nephrotoxicity, were also rare. Hence, response rates and toxic complications were lower than previously reported. We conclude that the MVP regimen has to be re-evaluated.

An autopsy case of meningeal spreading of glioblastoma multiforme (GBM) probably originating in the cervical cord was reported. In contrast to autopsy findings, main symptoms were similar to subacute meningitis, and any signs of myelopathy could not be detected during the clinical course. The patient was a 22-year-old man who was hospitalized because of a 2-week history of progressive headache following cough and slight fever. Vomiting and somnolence, developing 5 days before admission, were improved the day after a lumbar puncture performed at another hospital. On admission, meningeal signs, mild right abducens palsy, and depressed deep tendon reflexes were detected. There was no muscle weakness, sensory loss, or Babinski sign. Lumbar puncture yielded CSF with an opening pressure of 280 mmH2O, 21 mononuclear cells/mm3, a protein level of 645 mg/dl, and a glucose level of 7 mg/dl. Cytology for malignancy and multiple cultures were negative. Brain CT scan showed mild hydrocephalus and swelling of the brainstem and cerebellum. Intravenous administration of antimicrobial drugs was started and ventriculoperitoneal shunt surgery was performed. During the third hospital week, however, meningeal signs progressed and somnolence reappeared, followed by progressive multiple cranial neuropathy and polyradiculopathy characterized by flaccid tetraparesis, muscle atrophy, and sensory impairment without a level. Babinski sign could not be detected. MRI revealed an intramedullary lesion in the lower cervical cord, swelling of the brainstem, cerebellum, spinal cord and nerve roots, and a diffuse or nodular thickning of leptomeninges. Repeated CSF cytology disclosed atypical cells. Examinations for extraneural malignancies were negative. During the 9th hospital week, flaccid tetraplegia progressed and stupor developed, and the patient died 2 weeks later. The pathological study was limited to the brain. The brain showed a diffuse opalescent thickening of the leptomeninges, especially over the ventral aspect of the brainstem and cerebellum, where the blood vesseles and cranial nerves were obscured. Histological examination revealed the appearance of GBM. The malignant cells filled the subarachnoid space, and to a variable extent penetrated the brainstem and cerebellum along perivascular spaces. Hypertrophied optic tracts and trigeminal nerves were also infiltrated by the cells. However, there were no mass lesions assumed to be primary ones anywhere in the cerebral parenchyma. Therefore, it was thought that GBM primarily growing in cervical cord metastasized to intracranial subarachnoid space by way of the cerebrospinal fluid pathway. Spinal cord GBM usually presents signs of myelopathy from the early stage. The present case was characterized by no signs of myelopathy during the clinical course. It is speculated that the intramedullary GBM, originating near the surface of cervical cord, had been rapidly disseminated into the subarachnoid space up to the intracranial cavity before myelopathy appeared, and caused cranial and spinal nerve roots dysfunction, which covered signs of myelopathy. Cord GBM should be always considered as a differential diagnesis in a case of subacute meningitis.

We evaluated the activity and toxicity of two sequences of taxol combined with vinorelbine in disseminated malignant melanoma, metastatic beyond regional lymph nodes. Fifteen previously untreated patients, nine males and six females (median age 56 years), were enlisted between May 1994 and February 1995. Eight patients received vinorelbine 30 mg/m2 (maximum dose 50 mg) first, follow 24 h later by taxol 120 mg/m2 (maximum dose 240 mg) infused over 3 h (the V/T sequence). Seven patients received the reverse (T/V) sequence. In 79 administered courses there were no anaphylactic episodes, the main toxicity being alopecia (WHO grade 3). Significant neutropenia, emesis or neuropathy was not observed in either schedule (WHO grades 0 or 1). Three major responses, all with the V/T sequences, were seen; one complete (CR) in nodal and cutaneous sites lasting 13 months and two partial (PR), omental, ascites in one and hepatic, splenic and nodal in the other, lasting 7 and 6 months, respectively. Clinically meaningful tumor regressions, not qualifying strictly for the criteria of major response, were observed in two additional patients in the T/V sequence. Taxol combined with vinorelbine is active against disseminated malignant melanoma. The importance of sequencing the two drugs remains to be determined with accrual of more patients into the study.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is active against advanced breast cancer and anthracycline-resistant breast cancer. We assessed the efficacy and toxicity of doxorubicin followed by a 3-hour infusion of paclitaxel in women with advanced breast cancer. Participants could have received at most one prior adjuvant chemotherapy regimen, but no previous exposure to anthracyclines or taxanes was permitted. The patients were treated every 3 weeks with doxorubicin (50 or 60 mg/m2) followed 30 minutes later by paclitaxel (155, 175, or 200 mg/m2). After reaching the maximum cumulative doxorubicin dose, treatment could be continued with paclitaxel alone. Thirty women were included, of whom 29 were evaluable for response. The overall response rate was 83% (95% confidence interval, 64% to 94%), with 24% of patients attaining complete remission. Median response duration for complete responders was 8+ months (range, 4 to 13 months) and median time to progression was 9 months (range, 2 to 18 months). Main toxicities were neutropenia, paresthesia, nausea/vomiting, alopecia, myalgia, and cardiotoxicity. In 15 patients (50%), the left ventricular ejection fraction decreased to below normal levels; six patients (20%) developed congestive heart failure. In conclusion, the combination of doxorubicin and paclitaxel is highly active; dose-limiting toxicities are neutropenia, neuropathy, and cumulative cardiotoxicity.

In studies conducted by the Eastern Cooperative Oncology Group, treatment with either paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) or carboplatin was associated with an improvement in 1-year survival in patients with stage IV non-small cell lung cancer (NSCLC). Based on these findings, a phase II trial of carboplatin plus paclitaxel was conducted in patients with advanced NSCLC to determine the activity and toxicity of this regimen. Eligibility requirements included stage IIIB or IV histologically confirmed NSCLC, Eastern Cooperative Oncology Group performance status of 0 to 2, no prior chemotherapy, and adequate hematologic, renal, hepatic, and cardiac functions. Paclitaxel was administered intravenously over 24 hours at a dose of 135 mg/m2 (28 patients) or 175 mg/m2 (23 patients), followed by a 1-hour infusion of carboplatin on day 2. Carboplatin was administered at a dose of 300 mg/m2 (16 patients) or, using the Calvert formula, a dose calculated to achieve an area under the concentration-time curve of 6 mg/mL x min (35 patients). Treatment was repeated every 28 days for a total of six cycles. Among the 51 eligible patients, 34 were men and 17 were women; their median age was 60 years and their median Eastern Cooperative Oncology Group performance status was 1. Six patients had stage IIIB and 45 had stage IV disease. Grade 3 or 4 granulocytopenia and thrombocytopenia were observed in 47% and 3% of treatment cycles, respectively. The most common nonhematologic toxicities noted included nausea and emesis, neuropathy, and arthralgia and myalgia. There were no complete responses and 14 partial responses, for an overall response rate of 27% (95% confidence interval, 17% to 41%). Median survival was 38 weeks and the survival rate at 1 year was 32%. Paclitaxel plus carboplatin, as given in this study, was found to be a moderately active regimen in patients with advanced NSCLC. This regimen warrants comparison with existing cisplatin-based regimens in a prospective randomized trial.

Experimental data have suggested that the pineal hormone melatonin (MLT) may counteract chemotherapy-induced myelosuppression and immunosuppression. In addition, MLT has been shown to inhibit the production of free radicals, which play a part in mediating the toxicity of chemotherapy. A study was therefore performed in an attempt to evaluate the influence of MLT on chemotherapy toxicity. The study involved 80 patients with metastatic solid tumors who were in poor clinical condition (lung cancer: 35; breast cancer: 31; gastrointestinal tract tumors: 14). Lung cancer patients were treated with cisplatin and etoposide, breast cancer patients with mitoxantrone, and gastrointestinal tract tumor patients with 5-fluorouracil plus folates. Patients were randomised to receive chemotherapy alone or chemotherapy plus MLT (20 mg/day p.o. in the evening). Thrombocytopenia was significantly less frequent in patients concomitantly treated with MLT. Malaise and asthenia were also significantly less frequent in patients receiving MLT. Finally, stomatitis and neuropathy were less frequent in the MLT group, albeit without statistically significant differences. Alopecia and vomiting were not influenced by MLT. This pilot study seems to suggest that the concomitant administration of the pineal hormone MLT during chemotherapy may prevent some chemotherapy-induced side-effects, particularly myelosuppression and neuropathy. Evaluation of the impact of MLT on chemotherapy efficacy will be the aim of future clinical investigations.

Three members of a Taiwanese kindred developed severe, systemic, early onset (< age 25 years), biopsy-proven amyloidosis. Clinical features included upper and lower extremity sensorimotor neuropathy, abdominal pain, vomiting, corneal ulcerations, cardiomyopathy, and syncope. Immunohistochemical analysis indicated that the deposits consisted of transthyretin. Molecular genetic studies revealed a heterozygous codon 55 point mutation, resulting in a proline for leucine-substitution, a mutation previously associated with aggressive familial amyloidosis in a US kindred of Dutch and German descent. The clinical courses and echocardiographic findings are typical for many types of amyloidosis; the pathologic data and genetic studies were necessary to establish a precise diagnosis.
