A case of Guillain-Barré syndrome in a patient with non small cell lung cancer treated with chemotherapy.

Guillain-Barré Syndrome (GBS) is a demyelinating polyneuropathy of probable autoimmune pathogenesis characterized by rapidly progressive symmetric paralysis. In the literature some cases of GBS associated with anticancer chemotherapy are reported. We present a case of a 55-year old woman who complained of progressive motor deficit in four limbs, areflexia in lower limbs and facial nerve paralysis one week after beginning cisplatin-gemcitabine chemotherapy for metastatic lung cancer. The cerebrospinal fluid analysis showed a strong positive Pandy reaction with 435 mg/dl total protein. The electromyography and the electroneuronography established the diagnosis of inflammatory demyelinating polyneuropathy. Specific therapy with intravenous immunoglobulin 25 g/day in 5 administrations for 5 days was started with complete benefit.

A phase II study of pegylated liposomal doxorubicin oxaliplatin and cyclophosphamide as second-line treatment in relapsed ovarian carcinoma.

We carried out a phase II nonrandomized study to examine the level of activity of oxaliplatin, pegylated liposomal doxorubicin, and cyclophosphamide in a patient population with relapsed ovarian cancer pretreated with platinum derivatives and paclitaxel. Patients received oxaliplatin (85 mg/m2), pegylated liposomal doxorubicin (30 mg/m2), and cyclophosphamide (750 mg/m2). A total of 49 patients (39 assessable for toxicity and response) were enrolled in this trial. Neutropenia grade 3 was observed in six patients (15%) and anemia grade 3 in one patient (0.2%). Fatigue grade 1-2 occurred in 26 patients (66%), nausea/vomiting grade 1 in 23 patients (58%), and alopecia grade 1-2 in 19 patients (48%). Twenty-one (53%) patients experienced grade 1-2 peripheral neuropathy. The overall response rate was 46% (95% CI 23.6-68.7). Median progression-free survival was 28 weeks (range 12-52 weeks) and median survival was 45 weeks (range 26-136+ weeks). The mean duration of response was 34 weeks (range 16-52 weeks). In platinum-resistant and -refractory ovarian cancer patients, the overall response rate was 37% (CI 95% 14.4-60.8) with a progression-free survival of 28 weeks (range 12-52 weeks) and a median survival of 42 weeks (range 28-84 weeks). This combination chemotherapy is generally well tolerated and is an active second-line regimen against ovarian cancer.

The use of zoledronic acid in patients with bone metastases from prostate carcinoma: effect on analgesic response and bone metabolism biomarkers.

Zoledronic acid is a bisphosphonate that is effective in the treatment of complications of metastatic bone disease. We have carried out a perspective study on 24 consecutive patients with prostate cancer metastatic to bone to verify the effect of zoledronic acid on analgesic response and a possible relationship with the levels of bone metabolism biomarkers. Eligibility for this study required prostate cancer patients with metastatic bone disease and pain not controlled by analgesics. Patients were excluded from the study if they were receiving cytotoxic chemotherapy or radiation therapy within three months. Eighteen patients (75%) were considered responder to acid zoledronic, only 6 patients did not respond. Before starting treatment (T0) mean Visual Analogue Scale was 7.8 (SE +/- 0.29), after 1 month therapy (T1) was 3.6 (SE +/- 0.3) and after three months (T2) was 3.1 (SE +/- 0.4) with a significant difference between T0 and T1 (p<0.0005) and between T0 and T2 (p<0.0005). Visual Analogue Scale improvement was positively correlated with decrease of C-telopeptide and bone phosphatase alkaline (p<0.05) serum levels.

Home therapy for deep vein thrombosis and pulmonary embolism in cancer patients.

Outpatient treatment of deep vein thrombosis (DVT) has become a common practice in uncomplicated patients. Few data are still present in patients with comorbidity (such as cancer) or concomitant symptomatic pulmonary embolism. Cancer patients with DVT are often excluded from home treatment because they have a higher risk of both bleeding and recurrent DVT. We tested the feasibility and safety of the Home Treatment (HT) program for acute DVT a PE in cancer patients. Patients were treated as outpatients unless they required admission for other medical problems, were actively bleeding or had pain that requires parenteral narcotics. Outpatient treatment was with low molecular weight heparin (LMWH) followed by warfarin or with LMWH alone. An educational program for patients was implemented. Two-hundred and seven patients with cancer were evaluated, 36 (17.4%) of whom had metastatic disease. Treatment with LMWH and warfarin was prescribed to 106 (51.2%) and LMWH alone to 102 (48.8%). One hundred and twenty-seven patients (61.3%) were entirely treated at home. There were no differences between patients treated at home and hospitalized patients with regard to gender, mean age, site of cancer, presence of metastases, and treatment. After 6 months, recurrent thrombo-embolism occurred in 8.7% of patients treated at home and in 5.6% of hospitalized patients (P=0.58); major bleeding in 2.0% and 1.5%, respectively (P=0.06). Twenty-seven patients (33%) in the hospitalized, and 33 (26%) in the home-treatment group, died after a follow-up of 6 months. These results indicate that, regarding cancer patients with acute DVT and/or PE, there is no difference between hospitalised and home-treated patients in terms of major outcomes.
