It has been reported that chronic lymphocytic leukemia (CLL) often occurs concomitantly with other malignant neoplasms. However, because CLL is rare in Japan, there are only a limited number of reports of the occurrence of malignant neoplasia in Japanese patients with CLL. We report here the simultaneous occurrence of rectal cancer and CLL in a 57-year-old man. Because the clinical stage of CLL was Rai system I, we decided, in accordance with the National Cancer Institute-Sponsored Working Group guidelines, to monitor him without therapy for CLL until evidence of disease progression, and we performed abdominoperineal resection of the rectum for the cancer. The small rectal tumor was associated with aggressive lymphangiosis carcinomatosa, and multiple nodal metastases were observed in the pool of CLL cells. He died of rectal cancer 7 months after the operation, and autopsy revealed extensive metastases of the cancer. Cellular and humoral immunity is often impaired in patients with CLL, and the defective immunity in this patient may have had an etiological role in the development and rapid progression of the cancer. In the follow-up of CLL patients, we must always be aware of the possible existence of a second malignant disease. Particular attention should be paid to those with defective immunity, and screening should be performed, especially for pulmonary and gastrointestinal malignancies.

Ionizing radiation (IR) is an ever-present hazard to humans primarily due to its mutagenic, carcinogenic, and cell killing ability. In addition to causing DNA damage, irradiation initiates a plethora of signal transduction cascades responsible for maintaining cellular homeostasis and promoting interactions with neighboring cells. Large-scale changes in gene expression have also been found after irradiation, and microarrays have helped discern these subsequent transcriptional alterations. While some studies have focused on low dose-rate experiments, others have analyzed the gene expression response of IR compared to other DNA damaging agents. Very few genes have been found to be consistently up-regulated by IR, but that set includes GADD45, CDKN1A, and genes associated with the nucleotide excision repair pathway. Overall, the immediate transcriptional responses to IR have implications for DNA repair, cell cycle arrest, growth control, and cell signaling. Additionally, there is a substantial p53-independent component to the transcriptional profile that could be exploited to increase the effectiveness of radiotherapy. Initial characterizations of the persistent responses to IR yielded a completely different profile than observed immediately after exposure. This profile is ephemeral, shifting even over the course of one set of experiments. Microarray analysis of radiation responses has also been applied to clinical response to radiotherapy, identifying genes linked to radio-sensitivity and resistance in B-cell chronic lymphoid leukemia and cervical cancer. Overall, these large-scale gene expression studies have added to the understanding of the complicated biological responses to IR, and when combined with other data sets will yield a complete picture of the short and long-term consequences of radiation.

Chronic lymphocytic leukemia (CLL) is characterized by the clonal proliferation of small mature lymphocytes with their accumulation in blood, bone marrow, lymph nodes, spleen and lien. In advanced stages of CLL, the leukemic metastases can occur in skin, pleura and lungs. They are often strictly connected with disease progression and are present with advanced lymphadenopathy and hepatosplenomegaly, high leukocytosis 100G/1 with 80-90% lymphocytes in blood smear, anemia Hb <10 g% and thrombocytopenia PLT < 100 G/L. In this article we present two CLL patients with non typical leukemic metastases localization in bulbus oculi, vertebral column (case 1) and in thyroid gland and trachea (case 2), that occurred in hematological stabilization phase of disease during normal lymphocytes number or a little lymphocytosis in peripheral blood and a lack of progression in lymphoid organs.

Osteolytic lesions are rare in chronic lymphocytic leukaemia (CLL) and thought to result from Richter's transformation or metastatic disease from nonlymphoid malignancies. We report a patient who presented with a large femoral metastatic lesion and hypercalcaemia caused by CLL itself. Complete remission of CLL with resolution of the osteolytic lesion was achieved with rituximab and cyclophosphamide, adriamycin, oncovin and prednisolone [CHOP (R-CHOP)] combination chemotherapy.

In patients with chronic lymphocytic leukemia, squamous cell carcinoma behaves aggressively. Our purpose was to compare squamous cell carcinoma metastasis and mortality between patients with chronic lymphocytic leukemia and control subjects. Medical records were assessed retrospectively for 28 patients with chronic lymphocytic leukemia who underwent surgical excision of cutaneous squamous cell carcinoma and for 56 matched control subjects. The rate of metastasis and mortality from cutaneous squamous cell carcinoma were determined on a per-patient basis. Three of 28 patients with chronic lymphocytic leukemia had metastasis and died of metastatic disease. No metastases or deaths occurred among the 56 control subjects. Compared with control subjects, chronic lymphocytic leukemia patients with cutaneous squamous cell carcinoma were more likely to have metastasis (P = .0031) and die of metastasis (P = .0033). No significant association was detected between metastasis and history of chemotherapy administration for chronic lymphocytic leukemia. Among patients with chronic lymphocytic leukemia, surveillance for skin cancer and a decreased threshold for biopsy of suspect lesions are warranted.

We report the case of a 76-year-old patient with a past medical history of low-grade chronic lymphocytic leukaemia who presented with severe chronic bladder symptoms attributed to interstitial cystitis. She underwent cystectomy and ileal conduit formation after the failure of all conventional treatment. Bladder histopathology revealed primary splenic marginal zone lymphoma. Literature review shows the rarity of such non-hematopoietic visceral metastases. This may represent the first reported splenic marginal zone lymphoma with bladder involvement and highlights the clinical and histological similarities with interstitial cystitis.

There is lack of information about the relative prevalence of haematological disorders in Yemen and other Middle East countries. The aim of this study was to evaluate the pattern of haematological diseases diagnosed by bone marrow examination in Yemen considering the limited diagnostic facilities. At the referral haematology centre in Yemen, between November 1999 and November 2005, 785 patients >14 years old were evaluated by bone marrow examination. Relevant investigations were performed when needed. A total of 627 patients had haematological disorders other than lymphoma, and their data were analysed. There were 273 females and 354 males. A total of 159 patients had Acute myeloid leukaemia, 75 had acute lymphocytic leukaemia, 87 had chronic myeloid leukaemia, 36 chronic lymphocytic leukaemia, eight had multiple myeloma, 13 myelodysplastic syndromes, seven myelofibrosis, seven polycythaemia vera, three primary thrombocythaemia, two hairy cell leukaemia, two metastases, 36 aplastic anaemia, 29 immune thrombocytopenic purpura (ITP), nine autoimmune haemolytic anaemia, three pernicious anaemia, 65 iron deficiency anaemia, 57 megaloblastic anaemia and malaria, 18 mixed deficiencies, and 11 patients had visceral leishmaniasis. Sex- and age-related distribution of the various disorders was also presented. In conclusion, the leukaemias were the most frequently encountered diagnosis followed by iron deficiency anaemia, megaloblastic anaemia and malaria, aplastic anaemia and ITP respectively. The other haematological disorders were less common. These findings are comparable with that seen in other developing and developed countries.

Telomerase is one of the key enzymes responsible for the proliferative immortality of the majority of cancer cells. We recently introduced a new telomerase inhibitor, a 13-mer oligonucleotide N3' --> P5'-thio-phosphoramidate lipid conjugate, designated as GRN163L. This compound inhibits telomerase activity in various tumor cell lines with IC(50) values of 3-300 nM without any cellular uptake enhancers. GRN163L demonstrated potent and sequence specific anti-cancer activity in vivo in multiple animal models. This compound was able to significantly affect not only the growth of primary tumors, but also the spread and proliferation of metastases. GRN163L is currently in Phase I and Phase I/II clinical studies in patients with solid tumors and CLL, respectively.

The aim of this study was to analyze the value of cytology in differentiation between malignant epithelial tumor metastases and hematologic malignancy. The follow-up of ten (10) patients who underwent diagnosis and treatment of two malignant diseases, i.e. carcinoma and hematologic malignancy, was performed in the 2000-2005 period. The median of age of our patients was 72 years (range: 49-79). Cytological examination included epithelial tumors, lymph nodes and bone marrow standard Pappenheim and immunocytochemically stained smears. Carcinoma was initially diagnosed in 40% (4/10) patients and hematologic malignancy in 50% (5/10) patients, while both diseases co-occurred in one patient (1/10). Most of hematologic malignancy cases (4/10) were diagnosed as lymphoma. Multiple myeloma was diagnosed in 3 out of 10 patients (30%). Individual cases of acute myeloblastic leukemia, chronic lymphocytic leukemia, and chronic myeloid leukemia were diagnosed in the remaining three patients. Most carcinomas were breast cancer (8/10), while prostate and thyroid gland cancer were diagnosed each in one patient, respectively.

Multiple myeloma is a hemato-oncologic disease in the elderly population, with a peak incidence in the eighth decade, and represents a malignant bone marrow neoplasia in which a monoclonal strain of atypical plasma cells proliferates and may result in bone destruction. Skeletal metastases represent the most common malignant bone tumor and are the third most common location for distant metastases. They occur predominantly in adults, especially in the elderly population. Chronic lymphatic leukemia is a typical malignancy of the elderly patient and aplastic anemia is a hematologic disorder characterized by pancytopenia, bone marrow hypoplasia, and lack of extramedullary hematopoiesis. Osteomyelofibrosis and sclerosis are chronic myeloproliferative diseases of the elderly, with a peak incidence in the sixth and seventh decade of life. This article addresses these oncohaematologic disorders affecting the skeleton in the elderly, examining the radiographic scanning methods, staging, and prognosis for each.
