Malignant lymphomas have been reported previously to coincide with adenocarcinomas of the stomach and, rarely, the kidney, breast, colon, liver, or lung. Here, we describe the first case to our knowledge of a malignant lymphoma and an extensive disease small cell cancer of the lung. A 60-year-old male was admitted for severe back pain and was found to have multiple enlarged lymph nodes, hepatosplenomegaly, and bilateral pleural effusions. A B-cell non-Hodgkin's lymphoma (NHL) was diagnosed from biopsies of the stomach and liver. Further staging revealed a dense infiltration of the bone marrow by both a small cell lung cancer and a malignant lymphoma. Both tumors responded well to chemotherapy. This unique case report demonstrates that the simultaneous occurrence of small cell lung cancers and malignant lymphomas is extremely rare and may effectively be treated with chemotherapy.

Small blue cell tumors are a group of tumors that share a common histologic characteristic with H&E staining. This makes differentiation from one another difficult as they all appear small, blue and round. Even though they all appear the same, they are vastly different from each other. Several different techniques have been developed to help further delineate and classify these tumors which include: small cell lung cancer (SCLC); non-Hodgkin's lymphoma (NHL); Ewing's sarcoma; rhabdomyosarcoma; Merkel carcinoma; neuroblastoma; carcinoid tumors; and intra-abdominal desmpolastic small round cell tumor. Using immunoperoxidase staining, reverse transcriptase polymerase chain reaction and fluorescence in situ hybridization techniques, these tumors have been successfully differentiated from one another. This separation makes staging and treatment of these tumors more effective, as not all of these tumors respond to the same modality of treatment. The following review summarizes some of the recent findings in the various small blue cell tumors and with the potential of novel therapies.

The predominance of compact and nucleolonemic types of nucleoli in undifferentiated small cell carcinoma of lung, the prevalence of micronucleoli and ring-shaped types of nucleoli in lymphoid thymoma and the increase of the level of micronucleoli in small cell non-Hodgkin's lymphoma have been established.

This large population-based study focuses on the prognostic role of increasing age and co-morbidity in cancer patients diagnosed in the southern Netherlands. Data of patients diagnosed between 1995 and 2002 and recorded in the population-based Eindhoven Cancer Registry were used. Older patients (with serious co-morbidity) with non-small cell lung cancer or prostate cancer underwent surgery less often than younger patients. Elderly with stage III colon cancer, small cell lung cancer, FIGO II or III ovarian cancer or non-Hodgkin's lymphoma (NHL) received (adjuvant) chemotherapy less often, probably because of the higher rate of haematological complications. Administration of adjuvant radiotherapy decreased with age and co-morbidity in patients with rectal cancer, limited small cell lung cancer or breast cancer. In general, elderly did not suffer from more complications than younger patients, except for cardiac complications (colorectal cancer and NHL) and postoperative death (non-small cell lung cancer). For most tumours relative survival was lower for the elderly, except for patients with colon cancer, prostate cancer or indolent NHL. Co-morbidity had an independent prognostic effect, except for tumours with a very poor prognosis. Future prospective studies should investigate whether the guidelines for cancer treatment should be adjusted for elderly with serious co-morbidity.

Optimization of therapy for individual patients remains a goal of clinical practice. Radionuclide imaging can identify those patients who may benefit from subsequent targeted therapy by providing regional information on the distribution of the target. An ideal situation may be when the imaging and the therapeutic compounds are the same agent. Two antibodies ([ [90Y]ibritumomab, [131I]tositumomab) are now approved for the systemic radiotherapy of non-Hodgkin's lymphoma. The main hurdle is to deliver higher absorbed doses to the more refractory solid tumors paying particular regard to the bone marrow toxicity. The low dose is thought to be a result of the large size of antibodies slowing delivery to the target. Peptides having high affinity to receptors expressed on cancer cells are a promising alternative. They are usually rapidly excreted from the body through renal and/or hepatobiliary excretion thus creating a prolonged accumulation of the radioactivity in the kidneys, which represents a recognized issue for systemic radiotherapy. The first radiopeptide developed was a somatostatin analogue, which led to a major breakthrough in the field. Beside the kidney issue, somatostatin use remains limited to few cancers that express receptors in sufficiently large quantities, mainly neuroendocrine tumors. The gastrin releasing peptide (GRP) receptor is an attractive target for development of new radiopeptides with diagnostic and therapeutic potential. This is based upon the functional expression of GRP receptors in several of the more prevalent cancers including prostate, breast, and small cell lung cancer. This review covers the efforts currently underway to develop new and clinically promising GRP-receptor specific molecules labeled with imageable and therapeutic radionuclides.

Chemotherapy-associated neutropenia is often dose-limiting and may compromise treatment efficacy. Granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage-colony-stimulating factor (GM-CSF) are increasingly used to prevent febrile neutropenia (FN) or to increase dose-density. This review discusses recent changes in treatment guidelines for chemotherapy-associated neutropenia. Primary prophylactic use of CSFs is now recommended as a treatment option at an overall risk of FN of 20%, not taking into account cost-effectiveness. To estimate the risk of FN, patient-, disease-, and treatment-related factors predicting an adverse outcome of FN have been determined. Dose-dense chemotherapy has become feasible with the use of CSFs. However, clinical benefit has been shown only for specific chemotherapy regimens in breast cancer, small cell lung cancer (SCLC), and non-Hodgkin's lymphoma (NHL), for the latter particularly for patients above 60 years of age. Strategies are being developed to tailor the use of CSFs to patients with a high risk of adverse outcome of FN.

One limitation of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the size of the available needles, frequently yielding only cells for cytological examination. The aim of this pilot study was to evaluate the efficacy and safety of newly developed needle forceps to obtain tissue for the histological diagnosis of enlarged mediastinal lymph nodes. Patients with enlarged, positron emission tomography (PET)-positive lymph nodes were included. The transbronchial needle forceps (TBNF), a sampling instrument combining the characteristics of a needle (bevelled tip for penetrating through the bronchial wall) with forceps (two serrated jaws for grasping tissue) was used through the working channel of the EBUS-TBNA scope. Efficacy and safety was assessed. 50 patients (36 males and 14 females; mean age 51 yrs) with enlarged or PET-positive lymph nodes were included in this pilot study. In 48 (96%) patients penetration of the bronchial wall was possible and in 45 patients tissue for histological diagnosis was obtained. In three patients TBNF provided inadequate material. For patients in whom the material was adequate for a histological examination, a specific diagnosis was established in 43 (86%) out of 50 patients (nonsmall cell lung cancer: n=24; small cell lung cancer: n=7; sarcoidosis: n=4; Hodgkin's lymphoma: n=4; tuberculosis: n=2; and non-Hodgkin's lymphoma: n=2).No clinically significant procedure-related complications were encountered. This study demonstrated that EBUS-TBNF is a safe procedure and provides diagnostic histological specimens of mediastinal lymph nodes.

The association between Rosai-Dorfman Disease (RDD) and cancer was reported for the first time in 1984. However, there are still a small number of reports of this association. We describe a 60-year-old woman who presented with a focal onset motor seizure followed by tonic-clonic generalization and persistent headache. Magnetic Resonance Imaging disclosed an irregular hyperintense lesion in T2 and vasogenic edema in the left parietal region. Immunohistochemical analysis of a biopsy fragment was positive for protein S-100 and CD68 and negative for CD1a, compatible with the diagnosis of RDD. She previously had breast cancer six years earlier and had used tamoxifen for two years and anostrozol for three years after diagnosis of cancer. RDD has been already associated with different cancers, such as Hodgkin's lymphoma, non-Hodgkin's lymphoma, follicular lymphoma, melanoma, adenocarcinoma and small cell lung cancer. As far as we know, this is the first report of an association between breast cancer and RDD.
