Neurological syndrome after R-CHOP chemotherapy for a non-Hodgkin lymphoma: what is the diagnosis?

A 63-year-old man was admitted to our Oncology department for management of a follicular non-Hodgkin lymphoma, stage IV A FLIPI 5. The patient entered chemotherapy following the R-CHOP schedule, and a PET scan after three cycles showed partial remission. One week later he was admitted to our hospital after developing serious pain in his left arm resulting in an impaired function, right facial hemiplegia, and ophthalmoplegia. Neuroimaging studies and laboratory features were negative. Given his symptoms, we suspected Miller Fisher syndrome and the patient was administered high dose immunoglobulin, but showed no improvement. Finally, chemotherapy with methotrexate 3 g/mq was initiated, but his condition progressively worsened and the patient died 2 months later. We suggest that any patient with neurological symptoms who has received rituximab should undergo PCR analysis for all neurotropic viruses together with neurophysiological and neuroimaging studies.

Intrathecal chemotherapy in lymphomatous meningitis.

Central Nervous System (CNS) involvement in lymphoma can occur whether at diagnosis or, more often, at the progression or recurrence of disease and the most frequent clinical manifestation is lymphomatous meningitis (LM). The first risk factor for LM development is the histotype, with the highest incidence for highly aggressive non-Hodgkin's lymphomas (NHL) such as Burkitt's lymphoma (BL) and lymphoblastic lymphoma/acute lymphoblastic leukemia (LBL/ALL) and the lowest for indolent NHL. LM prophylaxis in aggressive NHL (other than BL and LBL/ALL) is a much debated question, because the identification of specific risk factors remains controversial. Moreover, there is not a consensus if the LM prophylaxis should consist of systemic chemotherapy (CT), intrathecal (i.t.) CT or both. In case of LM, the i.t. CT has a key role, but there is not a consensus on treatment schedule. Newer intensified regimens and rituximab lead to reconsider the whole approach to LM.

Management of Frail and Not-Frail elderly cancer patients in a hospital-based geriatric oncology program.

PURPOSE: To evaluate management and outcome of patients >or=70 years admitted to our Medical Oncology ward and evaluated by Multidimensional Geriatric Assessment before treatment with standard or "elderly-friendly" chemotherapy regimens, a list of which was developed within our Geriatric Oncology Program based on published clinical trials and personal experience. PATIENTS AND METHODS: Charts of patients treated from January 2004 to January 2006 were reviewed for choice of treatment, tumor response, toxicities and survival. RESULTS: 117 patients (median age 75 years) were divided into Frail (F) (34.2%) and Not-Frail patients (NF: 33.3% Fit plus 32.5% Vulnerable). The two groups did not differ according to the use of "elderly-friendly"chemotherapy regimens (40% of F pts and 39% of NF pts), dose reductions >or=25% (37.5% vs. 31.2%) and grade 3-4 toxicities (52.5% vs. 58.4%). Early interruption of treatment due to toxicity or patient's refusal (42.5 vs. 15.6, p=0.001) and deaths within 30 days from last chemotherapy administration (22.5% vs. 3.9%, p=0.003) were significantly different. F patients showed clinical or radiological response in 21.2% of cases, and subjective improvement in 22.6%. After a median follow-up of 19 months, median survival of F patients (6.4 months) is shorter compared to NF group (16.9 months, p=0.012). CONCLUSIONS: The use of "elderly-friendly"chemotherapy regimens was limited to less than a half of cases. F patients may respond to chemotherapy but display higher rates of premature withdrawal and early deaths compared to NF patients, with a shorter survival. Clinical trials particularly aimed at frail patients are urgently needed.

Increasing chemotherapy in small-cell lung cancer: from dose intensity and density to megadoses.

The hypothesis that increasing cytotoxic dose intensity will improve cancer cure rates is compelling. Although supporting evidence for this hypothesis has accrued for several tumor types, including lymphomas, breast cancer, and testicular cancers, it remains unproven. Small-cell lung cancer is extremely chemo- and radiosensitive, with a response rate of 80% achieved routinely, but few patients are cured by chemoradiotherapy. In this setting, increased cytotoxic dose intensity might improve cure rates. The finding that response rates in small-cell lung cancer correlate with received cytotoxic dose intensity merely confirms that "less is worse" and "more is better." Within conventional ranges, dose intensity can be increased with the support of hematopoietic growth factors and/or by shortening treatments intervals; however, dose intensity could be increased by only 20%-30%, and a survival advantage has not been clearly demonstrated. Given its high chemosensitivity, small-cell lung cancer was one of the first malignancies deemed suitable for increasing dose intensity and even for the use of a megadose with the support of autologous bone marrow transplantation. Some interest is emerging again due to improvements in supportive care, such as the availability of hematopoietic growth factors and peripheral blood progenitor cells.

Long-term clinical outcome of AIDS-related Kaposi's sarcoma during highly active antiretroviral therapy.

The long-term impact of highly active antiretroviral therapy (HAART) in AIDS patients with Kaposi's sarcoma (KS) was evaluated in 22 consecutive, HAART-naïve KS patients attending a single Italian referral centre for HIV/AIDS. Clinical, virologic and immunologic responses to HAART were assessed at baseline and every three months during the follow-up. Peripheral blood mononuclear cell (PBMC)-associated human herpesvirus 8 (HHV-8) load was also evaluated by real-time PCR in 13 patients with durable clinical KS complete response (CR). In a median follow-up of 40 months (range 17-78), the KS overall clinical response rate was 91%: 18 complete and 2 partial responses were achieved, and two patients experienced disease progression. CR persisted in all 18 patients, including the 5 poor-risk KS patients in whom CR lasted for > 60 months, and was significantly linked to an increase in CD4+ cell counts and a drop in HIV-1-RNA copies. Compared to baseline levels, a decrease in PBMC HHV-8 load was observed at CR, and a significant further reduction was found at the end of follow-up. In this monocentric study, AIDS-KS patients treated with HAART showed high clinical response rate. Patients with CR showed a prolonged remission, lasting more than 5 years in a group of poor-risk patients, and a persistent reduction in circulating HHV-8-infected cells. These findings highlight that HAART deeply modifies the natural history of this tumour in AIDS patients, and that this long-lasting approach may be considered a first-line treatment for the majority of HIV-1-infected patients developing KS.

Respiratory syncytial virus-related pneumonia after stem cell transplantation successfully treated with palivizumab and steroid therapy.

A case is reported of a 56-y-old woman with a second relapse of Hodgkin's disease who early developed after autologous stem cell transplantation (ASCT) a severe RSV-related interstitial pneumonia successfully treated with 1-d intravenous palivizumab 8 mg/kg plus low-dose systemic steroid therapy. B-cells suppression with CMV antigenaemia were then observed and required treatment with ganciclovir and liposomal amfotericine B.
