Thirty consecutive patients with stage IIIB-IV non small cell lung cancer were treated with a combination of cisplatin 80 mg/m2 on day 1 plus vinorelbine 25-30 mg/m2 on days 1, 8. This cycle was repeated every 3 weeks. The overall response rate was 46%, with 1 patient showing a complete response and 13 patients (43%) a partial response with a mean duration of 8.4+ months. Six patients had a stabilization and 10 progressed. The main toxicities were represented by myelosuppression and nausea/vomiting. Grade 3 leukopenia was seen in 33% of cases, grade 2 thrombocytopenia in 12%, and phlebitis in the injection vein in 16%. Mild constipation was also recorded. The combination of cisplatin plus vinorelbine is quite effective in advanced non small cell carcinoma of the lung, and may be safely given on an outpatient basis.

The purpose of the present study was to examine whether its is possible to successfully replace ondansetron (OND) with metoclopramide (MCP) in patients exposed to moderately emetogenic chemotherapy who did not experience severe nausea and vomiting while undergoing OND treatment during their first chemotherapy cycle. After switching to MCP, patients continued with this drug for three cycles, provided that they had adequate control of nausea and vomiting. Otherwise, they were switched back to OND. There were 76 patients, 60 women and 16 men, whose median age was 56 (mean 58) years. Karnofsky performance status score was 100 in 18 patients, 90 in 23, and 80 in 11 patients. No patient had previous chemotherapy. Thirty-four patients had breast cancer and received fluorouracil 500 mg/m2, epirubicin 100 500 mg/m2, and cyclophosphamide 500 mg/m2. Twelve patients had small cell lung cancer and received carboplatin 400 mg/m2 + etoposide 120 mg/m2 x 3 days. Twenty patients with ovarian cancer received carboplatin 350 mg/m2 and cyclophosphamide 500 mg/m2. Ten patients had cancer of unknown primary and received carboplatin 400 mg/m2, epirubicin 60 mg/m2, and etoposide 120 mg/m2 x 3 days. The OND schedule consisted of methylprednisolone 40 mg intravenous bolus followed by OND 8 mg in a 15-min infusion before chemotherapy, followed by OND 4 mg orally x 3 on the same and the next 2 days. Patients who did not experience nausea and vomiting with OND continued with an MCP schedule consisting of methylprednisolone 40 mg bolus followed by MCP 2 mg/kg in a 15-min infusion before chemotherapy, followed by MCP (20 mg x 4 on the day of therapy and the next 2 days after). Patients who failed with MCP or OND continued with OND. Considering our results as a whole, the intensity of nausea does not appear to influence the results of Gralla's scale. The results of Gralla's scale do not appear to be affected by the analysis of the antiemetic results and nausea on the next 2 days following chemotherapy administration. Overall, patients received 145 cycles with OND and 159 cycles with MCP. Of the 76 patients receiving OND-based antiemetic regimen during the first cycle, 13 (21%) experienced severe vomiting (Grade 2, 3) and the remaining 63 (79%) had mild or no vomiting (Grade 0, 1). Patients with Grade 0, 1 vomiting (63, 83%) continued with MCP in the second cycle. The final number of patients who failed on MCP, after 4 cycles of chemotherapy increased to 33 (43%); 43 (57%) were able to complete chemotherapy with MCP. Headache occurred in 15 (10%) cycles with OND and 8 (5%) with MCP. Flushing was noted in 12 (8%), and constipation occurred in 43 (30%) of OND cycles, and extrapyramidal manifestations occurred in 3 (5%) of patients receiving MCP. Diarrhea was noted in 3 (2%) of cycles with OND and in 28 (18%) with MCP. The cost ratio between MCP and OND was 1:14. If we administered OND only in patients who needed it, the overall cost decreased to 44%. Following the strategy applied in the present study, the cost decreased to 47%.

The Lambert-Eaton Myasthenic Syndrome (LEMS) is characterised by proximal muscle weakness initially affecting gait, autonomic symptoms (dry mouth, constipation, erectile failure), augmentation of strength during initial voluntary activation, and depressed tendon reflexes with post-tetanic potentiation. The disorder is paraneoplastic (small cell lung cancer) in about 60p. cent (P-LEMS); no cancer is associated in the remainder (NP-LEMS). LEMS affects all races. NP-LEMS can occur in childhood as well as adult life; P-LEMS is unusual at<30 Years. The weakness results from a reduction in the quantal release of acetylcholine from motor nerve terminals, caused by autoantibodies to P/Q-type voltage-gated calcium channels (VGCCs) that are provoked by tumour VGCCs in P-LEMS; the stimulus in NP-LEMS is not known. These antibodies may be implicated in the rarely associated cerebellar degeneration. The diagnosis can be confirmed by detecting the specific antibody in a radioimmunoprecipitation assay, and by finding a reduced compound muscle action potential amplitude that increases by>100p. cent following maximum voluntary activation. Most patients benefit from 3,4-diaminopyridine; pyridostigmine is less effective. Specific tumour therapy in P-LEMS will often ameliorate the neurological disorder. In those with severe weakness, IVIg or plasmapheresis confers short-term benefits. Prednisone alone or combined with azathioprine or cyclosporin can achieve long-term control of the disorder.

Paraneoplastic symptoms caused by abnormal gastrointestinal motility may be the initial manifestation of small cell lung cancer (SCLC). We report a case of a 63-year-old woman who presented with progressive constipation culminating in obstipation, and associated symptoms of more widespread dysmotility. A paraneoplastic syndrome was suspected. The only abnormality on chest computed tomography was a minimally enlarged paratracheal lymph node. Positron emission tomography demonstrated increased activity in the lymph node. The antinuclear neuronal antibody titer was elevated. Bronchoscopy with transtracheal biopsy confirmed the diagnosis of SCLC. One year after diagnosis, the patient had progressive symptoms of intestinal obstruction, and ultimately feculent vomiting. On abdominal radiography, colonic sitz markers ingested a year earlier were in virtually the same positions as after ingestion. Palliative colectomy with ileostomy was performed. The myenteric plexus in the terminal ileum and colon showed infiltration by a mixture of B-cell and T-cell lymphocytes and plasma cells, and no gross neuronal abnormalities. We review the clinical and pathologic features, clinical course, and management of paraneoplastic pseudoobstruction.

Small cell lung cancer (SCLC) is often associated with paraneoplastic neurological syndromes like intestinal pseudo-obstruction. This syndrome is characterized by dysmotility of the bowel without mechanical obstruction. The pathogenesis of the syndrome is thought to involve autoimmune mechanisms with production of antineuronal antibodies and enteric neuronal degeneration. We report a patient with severe constipation as a clinical presentation of a paraneoplastic intestinal pseudo-obstruction complicating SCLC, who was successfully treated with the somatostatin analogue octreotide. This may be explained by effects of hormone-like substances from the tumor directly inhibiting the gut motility, rather than by autoimmune mechanisms.

Small cell lung cancer (SCLC) has a very aggressive clinical progression with widespread metastases. We describe the case of a patient with SCLC treated with concurrent chemoradiotherapy. One month later, after finishing the scheduled treatment, the patient was admitted to the hospital again with symptoms of low back pain that radiated to bilateral lower legs with painful paresthesias, urinary incontinence, and constipation. After a series of examinations, including bone scan and magnetic resonance imaging, the patient received an L2-L3 laminectomy. The concluded diagnosis through histopathologic examination with immunohistochemistry was extramedullary-intradural spinal metastasis causing cauda equina syndrome. The metastatic tumour originated from the SCLC. To the best of our knowledge, this is the first reported case of SCLC metastasized to the cauda equina causing cauda equina syndrome.

A 53-year-old woman with chief complaints of vomiting and constipation was given a diagnosis of ileus and admitted to a local hospital. The origin of the ileus was unknown despite intensive examinations. However, her chest X-ray film and CT showed left hilar and mediastinal lymphadenopathy. Her pro-gastrin-releasing peptide (ProGRP) levels were elevated. After transfer to our hospital, the diagnosis of small cell lung cancer (SCLC) was confirmed by transbronchial aspiration cytology. Since no cause of ileus was found on laparotomy, her symptoms were considered to indicate chronic intestinal pseudo-obstruction (CIPO), a manifestation of paraneoplastic neurological syndrome. Serum anti-Hu antibody testing was positive. Chemoradiotherapy induced complete remission and her abdominal symptoms markedly improved. This is a very rare case of CIPO accompanied with SCLC, which improved after immediate anti-tumor therapy for lung cancer.

Cancer is related to a deterioration of nutritional status and quality of life (QoL), but the extent of these conditions in patients with Non Small Cell Lung Cancer (NSCLC) has not been studied. The aim of the present study was to assess the association between QoL and undernutrition in NSCLC patients. Nutritional status was evaluated with Patient Generated - Subjective Global Assessment and QoL using the European Organization for Research and Treatment of Cancer Quality of Life - C30 and also with the specific module for lung cancer patients. A consecutive sample of fifty six patients diagnosed with NSCLC was evaluated. A high proportion of patients is undernourished (35.7%), 1.8% in early stages vs 33.9% in advanced stages of disease. Undernutrition is related to measured dimensions of QoL: lack of appetite (rho=0.70), fatigue (rho=0.54), nausea and vomiting (rho=0.52) and constipation (rho=0.56). Undernourished patients have worse global health status, physical, emotional, social and role functioning. Patients with NSCLC have high frequency of undernutrition in advanced stages of disease. Undernourished patients present more symptoms, a worse global health status/QoL, physical, role, emotional and social functioning than patients without undernutrition. Undernutrition is associated with worse QoL, specifically in the parameters: appetite loss, nausea and vomiting, constipation and fatigue.

The treatment of the rare enteric nervous system (ENS) manifestations of paraneoplastic syndromes, which are most frequently associated with small cell lung cancer (SCLC), is poorly understood and described. Patients with neuroendocrine-derived tumors can develop B-cell reactivity towards the tumor with cross-reactivity for neurons located in the submucosal and myenteric ganglia of the ENS. The ensuing autoimmune neuritis causes aperistalsis and severe gastrointestinal (GI) dysfunction. Immune-directed therapy is not the standard of care but may be paramount for patient recovery. Our patient, a 63-year-old man with recent symptoms of esophageal dysmotility and newly diagnosed SCLC was hospitalized with nausea, emesis, and constipation. After an extensive work-up that included laparoscopy and celiotomy with bowel resection, we diagnosed what we refer to as Autoimmune Paraneoplastic Chronic Intestinal Pseudoobstruction (AP-CIPO). Unlike the few clinically similar reports, SCLC and AP-CIPO were diagnosed in our patient within weeks of each other, which presented the dilemma of treating the two processes simultaneously. In this report, we review the relevant literature and describe our patient's course. We believe standard chemotherapy is not effective treatment for AP-CIPO. Based on evidence discussed herein, we suggest initiating autoimmune-directed therapy before or simultaneous with cancer-directed therapy.

Although small cell lung cancer (SCLC) is initially sensitive to chemotherapy, it recurs in most cases. Standard regimens for salvage chemotherapy have not been established, and the prognosis of relapsed SCLC remains poor. In the present study, we investigated the clinical efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) regimens for the treatment of relapsed SCLC.In this retrospective multicenter analysis, 14 patients (3 women and 11 men; median age 71 years) with relapsed SCLC received nab-paclitaxel alone or in combination with carboplatin between February 2013 and July 2014. The safety and efficacy of the regimens were evaluated.The response rates, disease control rates, and median overall survival for the total patient population were 36%, 64%, and 7.8 months, respectively. Response rates, disease control rates, and the median overall survival were 11%, 44%, and 4 months, respectively, in the monotherapy group; and 80%, 100%, and 10.6 months, respectively, in the combination therapy group. The most common adverse events were hematological toxicities such as neutropenia and anemia. Severe neutropenia appeared in some patients, although it was resolved by treatment in all. The most common nonhematological toxicity was anorexia (64%), followed by neurotoxicity and constipation. All nonhematological toxicities were mild and manageable.Our results suggest that chemotherapy with nab-paclitaxel regimens for relapsed SCLC exhibits moderate clinical efficacy and is well-tolerated. Further clinical trials in relapsed SCLC patients are warranted.
