Paraneoplastic complications are obscure and difficult to understand. The association of motor neuron disease and carcinoma may sometimes be more than coincidental, and 2 cases are described. One patient had motor neuron disease, limbic encephalitis (a recognized paraneoplastic disorder) and carcinoma of the oesophagus; the other had motor neuron disease and adenocarcinoma of the rectum. In the elderly male with motor neuron disease simple screening tests to exclude lymphoma and carcinoma of the lung, bowel and genito-urinary tract are advocated.

We investigated the incidence of post-transplant solid tumors in a cohort of 109 patients who had undergone auto-peripheral blood stem cell transplantation (PBSCT) for acute myelogenous leukemia (n = 18), acute lymphoblastic leukemia (n = 7), non-Hodgkin's lymphoma (n = 52), Hodgkin's disease (n = 5), multiple myeloma (n = 16), chronic myelogenous leukemia (n = 1), myelodysplastic syndrome (n = 3) and solid tumors (n = 7). The patients were followed up for a median of 32 months after PBSCT. Five second solid malignancies developed in 4 patients within 14 to 43 months after PBSCT: large cell carcinoma of the lung, adenocarcinoma of the rectum, cholangiocellular carcinoma of the liver, squamous cell carcinoma of the mouth, and adenocarcinoma of the gallbladder. The affected patients were 3 of 52 with non-Hodgkin's lymphoma and one of 16 with multiple myeloma. One of the patients was in the 5th decade of life (n = 31) and 3 were in the 6th decade (n = 31). The cumulative actuarial risk for developing post-transplant solid tumors was 8% at 8 years. Elderly patients (> or = 60 year old) who have undergone PBSCT need to be observed carefully for second neoplasms because of their increased risk of post-transplant solid tumors.

This paper describes the synthesis and properties of two new palladium(II) complexes with 2,6-dimethyl-4-nitro-pyridine (dmnp): mononuclear [Pd(dmnp)2Cl2] and dinuclear [Pd2(dmnp)2Cl4]. Complexes were characterized on the basis of chemical and chromatographic analyses, MS and conductometric measurements, as well as by IR and NMR (1H and 13C) spectral studies. The crystal structures of ligand and mononuclear complex, trans-dichlorobis(2,6-dimethyl-4-nitro-pyridine)palladium(II), were determined by three-dimensional X-ray methods. The crystals of both compounds are monoclinic, space groups P21/c with a=19.075(4), b=5.419(1), c=15.045(3) A and beta=108.15(3)degrees for (dmnp), and a=7.544(2), b=14.509(3), c=8.032(2) A and beta=90.32(3)degrees for [Pd(dmnp)2Cl2]. In the (dmnp) there are two crystallographically independent molecules in the unit cell. The nitro groups and methyl C atoms are coplanar with the ring plane. The hydrogen bond of the type C-H...O links the molecules into pairs around center of symmetry. These dimers are held together by contacts of the van der Waals type. In the crystal structure of [Pd(dmnp)2Cl2] the Pd atom lies on an inversion center and is four-coordinated by two pyridine N atoms and by two Cl atoms in trans positions. The coordination geometry is square-planar, with Pd-N and Pd-Cl distances of 2.033(2) and 2.311(1) A, respectively. The two pyridine rings are mutually parallel, but they are twisted from the PdN2Cl2 coordination plane by about 88.5degrees. The preliminary assessments of anti-tumor properties of both complexes and ligand were evaluated as in vitro anti-proliferative activity in four human cancer cell lines: SW707 (adenocarcinoma of the rectum), T47D (breast cancer), HCV (bladder cancer) and A549 (non-small cell lung carcinoma). The [Pd(dmnp)2Cl2] exhibits strong cytotoxic activity against all cell lines whereas the free ligand and dinuclear [Pd2(dmnp)2Cl4] are only moderate active.
