Based on the results of our previous pilot study, we conducted a multi-institutional phase II study of combination chemotherapy consisting of oral UFT (Taiho Pharmaceutical Co. Ltd, Tokyo) plus cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). UFT capsule containing 100 mg tegafur and 224 mg uracil was orally administered in two divided doses on days 1 through 21 making the total tegafur dose 400 mg/m(2)/day (maximum 600 mg/body). CDDP was administered by drip infusion at a dose of 20 mg/m(2) on a 5-day schedule from day 8 to 12. Treatment was repeated every 4 weeks as long as the criteria for initiation of therapy were still met. Between April 1995 and March 1997, 51 patients were entered into the study. The mean age of all 50 eligible patients was 64 years(range: 40-78). There were 21 patients with clinical stage IIIB disease and 29 patients with IV disease. Thirty-two patients had adenocarcinoma, 14 had epidermoid carcinoma, and four had large cell carcinoma. Of the 47 assessable patients, 18 achieved a partial response with an overall response rate of 38.3% (95% confidence interval: 24.4-52.2%). The median response duration was 113 days. The median survival time of the eligible patients was 12.8 months, and the 1-year survival rate was 54%. Among the 51 patients enrolled, grade 3 or 4 leukopenia developed in one patient (2%), neutropenia in six patients (11. 8%), thrombocytopenia in six patients (11. 8%), and anemia in three patients (5. 9%). Non-hematological grade 3 or 4 toxicities included anorexia in 10 patients (19.6%), nausea in ten (19.6%), vomiting in two (3.9%), and diarrhea in two (3. 9%). Grade 3 abnormal laboratory data included bilirubinemia in four (7. 8%), GPT elevation in one (2.0%), and hematuria in one (2.0%). In conclusion, combination of CDDP plus oral UFT is efficacious, with low toxicity, in the treatment of advanced NSCLC. In particular, the low hematological toxicity may warrant application of this regimen to the treatment of elderly patients and in trials of concurrent chemoradiotherapy in patients with locally advanced NSCLC.

Best Supportive Care (BSC) is the treatment of choice when cure is not achievable with anticancer treatments and involves management of disease-related symptoms. In the palliative treatment of non-small cell lung cancer (NSCLC) radiation therapy has for a long time been the cornerstone of symptom management, although the best schedule is still to be defined. Chemotherapy, on the other hand, has been excluded from classical definitions of BSC and has been reserved only for selected patient populations in which a survival benefit was demonstrated using cisplatin-based regimens. We reviewed randomized trials on both palliative radiotherapy and chemotherapy in order to assess the impact of anticancer treatments on quality of life in advanced NSCLC patients. While no randomized trials compared radiation therapy with a control arm not including it, several randomized trials assessed the use of different schedules. Hypofractionated schedules seem to have comparable palliative activity when compared with the standard fractionated regimens, at least in metastatic, poor-prognosis patients. In locally advanced, inoperable NSCLC higher radiation doses administered with conventional fractionation achieve better results in terms of local control and survival. The rate of palliation of local symptoms is high, being 60-80% for chest pain and hemoptysis, while breathlessness and cough are controlled at a somewhat lower rate (50-70%). General symptoms (fatigue, anorexia, and depression) are affected in a minority of patients. Chemotherapy was compared with BSC in several randomized trials, in some of which an analysis of the quality of life was included. Results are consistent in favor of its palliative role and, when local symptom control is assessed, rates of palliation seem similar to those achieved by radiation. Benefits apply to metastatic NSCLC patients with good performance status, low body weight loss, age below 70-75. However, some studies support the use of chemotherapy also in patients with poor prognostic features. A comparison in terms of quality of life and symptom palliation between different chemotherapy regimens is the object of few trials. Both chemotherapy and radiation have an important role in the palliative treatment of advanced NSCLC patients and should be included in BSC programs. Future randomized trials should assess the best way of combining these two approaches.

We report the case of a patients with a metachronous cystic pancreatic metastasis from an undifferentiated large cell lung carcinoma two years after the primary tumor had been surgically removed. Clinically, he presented with epigastric pain, fever, weakness and anorexia. The patient was operated and a palliative cystogastrostomy was performed after an intraoperative biopsy had been informed as positive for carcinoma. Six months later the patient died. Pancreatic metastases from lung carcinoma are found in approximately 7-9% of patients deceased of this neoplasm. Clinical and radiological findings simulate primary pancreatic tumors, being epigastric pain, jaundice and upper digestive bleeding the most frequent symptoms. They represent stages of advanced systemic disseminated tumoral disease, and because of this reason total or partial surgical curative resections will only be performed in a few cases of patients with isolated metastasis, criteria of resectability and without evidence of extended disease to other organs or systems. In the most of the cases, the treatment will only be palliative, even medical or surgical.

Autoimmune impairment and destruction of the enteric nervous plexus are thought to play a central role in the pathogenesis of paraneoplastic motility disorders. We present a case of a small-cell lung carcinoma-related paraneoplastic motility disorder associated with abnormal interstitial cells of Cajal networks. Antibodies against c-Kit and protein gene product 9.5 were used to selectively stain interstitial cells of Cajal and the enteric nervous plexus, respectively. A 68-yr-old man presented with anorexia, early satiety, nausea, and weight loss. Investigations revealed gastroparesis, delayed small intestinal transit, and mediastinal lymphadenopathy. The patient was seropositive for type 1 antineuronal nuclear autoantibody and P/Q-type calcium channel antibody. Biopsy of mediastinal lymph nodes revealed metastatic small-cell carcinoma cells that were immunoreactive for c-Kit. Immunohistochemical staining of a full-thickness small intestinal biopsy revealed a relatively intact myenteric plexus but a sparse and disorganized interstitial cells of Cajal network. The histopathology of this case suggests that interstitial cells of Cajal may be a target in the pathogenesis of paraneoplastic motility disorders.

We reported a 62-year-old woman had sensorimotor neuropathy with small cell lung carcinoma (SCLC) and anti-GM1 antibody. She was admitted with several months history of progressive numbness, walking disturbance and anorexia. Neurologic examination revealed severe numbness and deep sensory disturbance of extremities and body, and mild weakness of distal extremities. Deep tendon reflexes were absent. Her limbs were ataxic. Nerve conduction studies showed no sensory evoked responses. CSF protein was elevated. Sural nerve biopsy revealed severe loss of myelinated fibers and perivascular mononuclear cells surrounding the perineurial vessel. Vasculitic neuropathy was diagnosed, and prednisolone was started, with no benefit. In the clinical course, she developed cough attacks and was found the lymphnode swelling in the mediastinum and supraclavicular fossa, which was diagnosed SCLC. Although anti-Hu antibody were not detected, anti-GM1 antibody was positive. She was treated with intravenous immunoglobulin, with transient improvement. The rare case of the paraneoplastic peripheral neuropathy with SCLC and anti-GM1 antibody was reported.

Small-cell lung cancer (SCLC) is highly chemosensitive but up to 70% of patients with limited disease and more than 90% of patients with extensive disease will relapse after first-line treatment. There are several standard chemotherapy regimens used for second-line treatment yet the prognosis for patients requiring this treatment remains poor. The topoisomerase-I inhibitor, topotecan, has achieved response rates of up to 22% in previously treated patients with SCLC and survival almost double that achieved with other single agents. Compared with cyclophosphamide/doxorubicin/vincristine (CAV), single-agent topotecan achieved a higher response rate, longer survival and statistically significant improvements in dyspnea, hoarseness, fatigue, anorexia and interference with daily activities. Brain metastases are common in SCLC. Topotecan crosses the blood-brain barrier and shows promise for the management of brain metastases.

Parathyroid hormone-related protein (PTHrP) plays a central role in humoral hypercalcemia of malignancy (HHM), which is one of the most frequent paraneoplastic syndromes. PTHrP produced by the tumor acts through a common PTH/PTHrP receptor to promote bone resorption, inhibit calcium excretion from the kidney, and induce hypercalcemia. Patients with HHM often develop cachexia associated with typical symptoms such as anorexia, malaise, nausea, constipation, polyuria, polydipsia, and confusion. The etiology of the cachexia is not fully understood but is thought to be caused by hypercalcemia and various cytokines such as interleukin-6, tumor necrosis factor-alpha, leukemia inhibitory factor, and others. In this study, we investigated the role of PTHrP in hypercalcemia and cachexia in HHM by using humanized anti-PTHrP antibody. A mouse monoclonal antibody that binds to PTHrP amino acid sequence 1-34 and inhibits PTHrP function has been humanized to create a specific and potent agent for the treatment of patients with HHM. The mouse monoclonal antibody has been shown to have antihypercalcemic activity against nude mice bearing human tumors. Because a mouse antibody is highly immunogenic in human patients, the complementarity-determining regions from the mouse antibody were grafted into a human antibody. The resulting humanized antibody specifically recognizes PTHrP(1-34) and neutralizes PTHrP functions in vitro and in vivo. The humanized anti-PTHrP antibody was administered intravenously to HHM model animals bearing tumors such as LC-6 human lung carcinoma. These animals showed symptoms similar to those of patients with HHM (eg, hypercalcemia and cachexia). The humanized anti-PTHrP antibody-treated animals responded with normalization of blood ionized calcium level through an improvement of bone metabolism and calcium excretion. Moreover, the treated animals also showed an improvement in body weight, ultromotivity, metabolic alkalosis, food consumption, water intake, serum phosphorus, and renal function. Consequently, the humanized antibody-treated animals experienced complete resolution of hypercalcemia and cachexia. These results suggest that the humanized antibody would be an effective and beneficial agent for patients with HHM, and that PTHrP is a major pathogenetic factor of hypercalcemia and cachexia in patients with HHM.

AE-941 (Neovastat), an antiangiogenic component extracted from cartilage, selectively competes for the binding of vascular endothelial growth factor to its receptor, inhibits matrix metalloproteinases, stimulates tissue plasminogen activator enzymatic activities, and induces apoptotic activities in endothelial cells. A phase I/II study was conducted to obtain information on its safety and efficacy in patients with advanced cancer refractory to treatment or for which no standard treatments were available. Eighty patients with histologically confirmed lung cancer were enrolled in a multicenter, open-label, dose-escalation study of AE-941 (30, 60, 120, or 240 mL/day) administered orally b.i.d. as monotherapy. No dose-limiting toxicity was reported. The most frequent adverse events were nausea (9%), pruritus (5%), anorexia (4%), and vomiting (4%). All adverse events were grade 1/2 except grade 3 constipation (n = 1). A survival analysis was conducted in the 48 patients with unresectable stage IIIA, IIIB, or IV non-small-cell lung cancer. A significant survival advantage was observed for patients receiving doses > 2.6 mL/kg/day (which correspond to approximately 180 mL/day in a 70-kg patient) compared to patients receiving lower doses (median, 6.1 months vs. 4.6 months; P = 0.026). No tumor responses were observed. On the other hand, 26% of the patients in the high-dose group had stable disease compared to 14% in the low-dose group. AE-941 is well tolerated in patients with advanced lung cancer. The higher dose of AE-941 explored in this phase I/II trial may confer a survival benefit.

Despite improvements in conventional treatment, patients with advanced non-small-cell lung cancer (NSCLC) have a poor prognosis, leaving a significant unmet need for novel treatments. One such novel, biologically targeted agent is the orally active epidermal growth factor receptor tyrosine kinase inhibitor gefitinib. This open-label pilot trial investigated the safety, pharmacokinetics, and efficacy of 2 doses of gefitinib (250 and 500 mg per day) combined with docetaxel (75 mg/m2) in patients with locally advanced or metastatic NSCLC as first- and second-line chemotherapy. Eighteen patients were recruited: 6 received gefitinib 250 mg per day plus docetaxel; 12 received gefitinib 500 mg per day plus docetaxel. Combination therapy was feasible with no overlapping toxicities. No patients experienced dose-limiting toxicities (DLTs) at 250 mg per day; 1 patient had 2 DLT events at 500 mg per day (grade 3 rash and diarrhea for >4 days). Adverse events were mild to moderate, including fatigue, mucositis, nausea, anorexia, rash, diarrhea, and fever. Docetaxel did not appear to alter steady-state exposure to gefitinib. The effect of gefitinib on exposure to docetaxel was equivocal; with the exception of 2 patients in the gefitinib 250 mg per day dose group, there appeared to be no trend toward a higher or lower exposure to docetaxel when given in the presence of gefitinib compared with that when given alone. Combination therapy was associated with antitumor activity and responses were seen with gefitinib in 2 of 6 patients at 250 mg per day and 4 of 12 patients at 500 mg per day. This combination is feasible and has an acceptable and predictable safety profile, as well as associated antitumor activity.

Exisulind is a sulfone derivative of sulindac that induces apoptosis and demonstrates synergy with docetaxel in lung cancer models. This study evaluated the safety, efficacy, and pharmacokinetic interactions of exisulind and docetaxel/carboplatin in patients with metastatic non-small-cell lung cancer (NSCLC). Fifty-seven patients received 218 cycles of docetaxel (75 mg/m2) and carboplatin (area under the curve, 5.0) in combination with exisulind (125-250 mg orally twice daily). Two complete responses and 9 partial responses were observed among the 47 patients assessable for response (overall response rate, 23%). The median duration of response was 5.9 months and median survival was 9.4 months. The 1- and 2-year survival rates are 35% and 14%, respectively. The hematologic toxicities were consistent with those previously reported with docetaxel/carboplatin. The most common nonhematologic toxicities were mild to moderate fatigue, anorexia, nausea, and vomiting. The addition of exisulind to the chemotherapy regimen did not interfere with the metabolism or elimination of docetaxel and vice versa, and docetaxel did not interfere with the pharmacokinetic parameters of exisulind. This trial did not allow direct comparison of patients receiving docetaxel/carboplatin with and without exisulind, but when compared with historical data of docetaxel/carboplatin alone, the addition of exisulind does not appear to enhance antitumor activity, duration of response, or survival. Although preclinical data demonstrate increased apoptosis and prolonged survival for the combination of exisulind and docetaxel, multiple clinical trials do not support further clinical development of this combination regimen in patients with advanced NSCLC.
