Because Cisplatin potentiates the effect of radiotherapy in animal tumor systems and because Cisplatin is capable of causing regressions of human malignant melanomas, a study was initiated in patients with malignant melanoma metastatic to brain to investigate the feasibility of administering Cisplatin once a week during cranial irradiation. Cisplatin 40 mg/m2/week (three doses) was given I.V. to 18 patients during whole brain irradiation, 3 000 rads in 12 fractions over 21/2 weeks. Eleven patients also received Cisplatin 120 mg/m2 every three weeks, starting three weeks after cranial irradiation. Median survival was ten weeks, and only one of 13 patients whose brain metastases had not been resected experienced neurological and CT scan improvement. Thirteen patients have died, and brain metastases were a major cause. No regression of extracerebral tumor was seen in 15 patients with evaluable extracerebral lesions. During weekly low-dose Cisplatin administration, nausea and vomiting were moderate to severe. No granulocytopenia was noted, although three courses were associated with mild thrombocytopenia. Mucositis, peri orbital swelling, vertigo, and headache were each noted in two of 51 courses of treatment and seizures, ototoxicity, pancreatitis, and hiccups were each noted in one course. Renal toxicity and ototoxicity each developed in three of the 11 patients receiving Cisplatin 120 mg/m2, and nausea and vomiting were severe.

Mitochondriopathies (MCPs) are either due to sporadic or inherited mutations in nuclear or mitochondrial DNA located genes (primary MCPs), or due to exogenous factors (secondary MCPs). MCPs usually show a chronic, slowly progressive course and present with multiorgan involvement with varying onset between birth and late adulthood. Although several proteins with signalling, assembling, transport, enzymatic function can be impaired in MCP, most frequently the activity of the respiratory chain (RC) protein complexes is primarily or secondarily affected, leading to impaired oxygen utilization and reduced energy production. MCPs represent a diagnostic challenge because of their wide variation in presentation and course. Systems frequently affected in MCP are the peripheral nervous system (myopathy, polyneuropathy, lactacidosis), brain (leucencephalopathy, calcifications, stroke-like episodes, atrophy with dementia, epilepsy, upper motor neuron signs, ataxia, extrapyramidal manifestations, fatigue), endocrinium (short stature, hyperhidrosis, diabetes, hyperlipidaemia, hypogonadism, amenorrhoea, delayed puberty), heart (impulse generation or conduction defects, cardiomyopathy, left ventricular non-compaction heart failure), eyes (cataract, glaucoma, pigmentary retinopathy, optic atrophy), ears (deafness, tinnitus, peripheral vertigo), guts (dysphagia, vomiting, diarrhoea, hepatopathy, pseudo-obstruction, pancreatitis, pancreas insufficiency), kidney (renal failure, cysts) and bone marrow (sideroblastic anaemia). Apart from well-recognized syndromes, MCP should be considered in any patient with unexplained progressive multisystem disorder. Although there is actually no specific therapy and cure for MCP, many secondary problems require specific treatment. The rapidly increasing understanding of the pathophysiological background of MCPs may further facilitate the diagnostic approach and open perspectives to future, possibly causative therapies.
