The aim of the present study was to investigate, in human lung cancer, the relationship between weight loss and the existence of a low body cell mass (BCM) on the one hand, and the putative presence of systemic inflammation, an increased acute-phase response, anorexia, hypermetabolism and changes in circulating levels of several anabolic and catabolic hormones on the other. In 20 male lung cancer patients, pre-stratified by weight loss of >/=10% (n=10) or of <10% (n=10), the following measurements were performed: BCM (by dual-energy X-ray absorptiometry/bromide dilution), circulating levels of sTNF-R55 and sTNF-R75 (soluble tumour necrosis factor receptors of molecular masses 55 and 75 kDa respectively), interleukin-6, lipopolysaccharide-binding protein, albumin, appetite (scale of 0-10), resting energy expenditure (by indirect calorimetry) and circulating levels of catabolic (cortisol) and anabolic [testosterone, insulin-like growth factor-I (IGF-I)] hormones. Compared with the patients with a weight loss of <10%, those with a weight loss of >/=10% were characterized by higher levels of sTNF-R55 (trend towards significance; P=0.06), and lower levels of albumin (27.4 compared with 34.4 mmol/l; P=0.02), testosterone (13.2 compared with 21.5 nmol/l; P=0.01) and IGF-I (119 compared with 184 ng/ml; P=0.004). In the patient group as a whole, the percentage weight loss was significantly correlated with sTNF-R55 (r=0.59, P=0.02), albumin (r=-0.63, P=0.006) and IGF-I (r=-0.50, P=0.02) levels. Height-adjusted BCM was significantly correlated with sTNF-R55 (r=-0.57, P=0.03), sTNF-R75 (r=-0.50, P=0. 04), lipopolysaccharide-binding protein (r=-0.50, P=0.04), albumin (r=0.56, P=0.02) and resting energy expenditure/BCM (r=-0.54, P=0. 03), and there was a trend towards a correlation with IGF-I concentration (r=0.44, P=0.06). We conclude that, in human lung cancer, weight loss and the presence of a low BCM are associated with systemic inflammation, an increased acute-phase response and decreased levels of IGF-I. In addition, a decreased BCM is associated with hypermetabolism.

Based on the role of cytokines in the pathogenesis of cancer-related anorexia-cachexia and the ability of progestins, such as medroxyprogesterone acetate, to reduce cytokine production and relieve cancer-related anorexia-cachexia symptoms, the authors designed an open, dose-finding phase I study of a combined chemotherapy regimen (cisplatin [CDDP], epidoxorubicin [EPI]), including recombinant interleukin-2 (IL-2) and medroxyprogesterone acetate for patients with stage IIIB to IV inoperable primary lung cancer. The end points were clinical response and toxicity with definition of dose-limiting toxicity and maximal tolerable dose; relief of cancer-related anorexia-cachexia symptoms; the assessment of patient serum levels of IL-1beta, IL-6, tumor-necrosing factor-alpha (TNF-alpha), and soluble IL-2 receptor (sIL-2R). From March to October 1997, 16 patients (M:F ratio, 14:2; mean age, 60.5 years; age range, 41 to 74 years) were enrolled. All patients were evaluable for toxicity and 14 of them for response. The patients were assigned to increasing dose levels of drugs according to a dose-escalation schedule. The weekly schedule consisted of a combination of CDDP given intravenously on day 1, EPI given intravenously on day 1, 1 g/day medroxyprogesterone acetate given orally on days 1 to 7, and recombinant IL-2 1.8 MIU administered subcutaneously on days 2 to 7 plus 300 microg granulocyte-colony stimulating factor support given subcutaneously on days 2 to 5. Administration of medroxyprogesterone acetate began 1 week before the first cycle. Dose escalation of the drugs was as follows: 30 mg x m2 x week(-1) CDDP and 25 mg x m2 x week(-1) EPI (first level, two patients); 30 mg x m2 x week(-1) CDDP and 33 mg x m2 x week(-1) EPI (second level, 2 patients); 40 mg x m2 x week(-1) CDDP and 33 mg x m2 x week(-1) EPI (third level, 6 patients); and 40 mg x m2 x week(-1) CDDP and 40 mg x m2 x week(-1) EPI (fourth level, 6 patients). Six cycles were planned for each patient. The actual dose intensity delivered was more than 80% of the projected dose intensity of all drugs. After six cycles, clinical response (according to World Health Organization criteria), toxicity (according to World Health Organization criteria), Eastern Cooperative Oncology Group (ECOG) performance status, body weight, appetite, and serum levels of cytokines were evaluated. After six cycles, 9 of 14 patients (64.3%) had partial response, 3 of 14 (21.4%) had stable disease, and 2 of 14 (14.3%) had progressive disease, and the objective response rate was 64.3%. ECOG performance status and body weight did not change significantly after treatment, whereas appetite showed an increase that was of borderline statistical significance. Toxicity was acceptable and only hematologic. Dose-limiting toxicity was established at the fourth dose level; consequently, maximal tolerable dose was assessed at the third dose level. Before treatment, the serum levels of IL-1beta, IL-6, and TNF-alpha were significantly greater in the patients than in healthy persons. The comparison between pretreatment and posttreatment serum values of IL-1beta, IL-6, TNF-alpha, and sIL-2R did not reveal significant differences in the patients. Similar results were obtained when the patients were considered as responders (partial response) or non-responders (stable or progressive disease) to therapy. Only IL-6 serum levels were increased (p = 0.014) after treatment.

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.

A 21-year-old man presented persistent dry cough, general malaise, loss of appetite, decreased sexual desire and double vision. Chest radiograph revealed a mass shadow in the left upper lobe. Histopathological diagnosis of the tumor was squamous cell carcinoma. Brain computed tomography and magnetic resonance imaging revealed a metastasis to the pituitary gland. Hypopituitarism was diagnosed by pituitary function tests. Diabetes insipidus was absent and the function of the posterior lobe of the pituitary gland was preserved. Hypopituitarism due to pituitary metastasis is a rare complication of lung cancer, and has never been reported in a patient as young as 21 years old.

The purpose of this study was to evaluate the efficacy and safety of a novel oral anticancer fluoropyrimidine derivative, S-1, in patients receiving initial chemotherapy for unresectable, advanced non-small-cell lung cancer (NSCLC). Between June 1996 and July 1998, 62 patients with NSCLC who had not received previous chemotherapy for advanced disease were enrolled in this study. 59 patients (22 stage IIIB and 37 stage IV) were eligible for the evaluation of efficacy and safety. S-1 was administered orally, twice daily, after meals. 3 dosages of S-1 were prescribed according to body surface area (BSA) so that they would be approximately equivalent to 80 mg m(-2)day(-1): BSA < 1.25 m(2), 40 mg b.i.d.; BSA> or =1.25 but <1.5 m(2); 50 mg b.i.d., and BSA> or =1.5 m(2): 60 mg b.i.d. One cycle consisted of consecutive administration of S-1 for 28 days followed by a 2-week rest period, and cycles were repeated up to 4 times. The partial response (PR) rate of the eligible patients was 22.0% (13/59); (95% confidence interval: 12.3-34.7%). A PR was observed in 22.7% (5/22) of the stage IIIB patients and 21.6% (8/37) of the stage IV patients. The median response duration was 3.4 months (1.1-13.7 months or longer). Grade 4 neutropenia was observed in one of the 59 patients (1.7%). The grade 3 or 4 toxicities consisted of decreased haemoglobin level in 1.7% of patients (1/59), neutropenia in 6.8% (4/59), thrombocytopenia in 1.7% (1/59), anorexia in 10.2% (6/59), diarrhoea in 8.5% (5/59), stomatitis in 1.7% (1/59), and malaise in 6.8% (4/59), and their incidences were relatively low. There were no irreversible, severe or unexpected toxicities. The median survival time (MST) of all patients was 10.2 months (95% confidence interval: 7.7-14.5 months), and the one-year survival rate was 41.1%. The MST of the stage IIIB patients was 7.9 months, and that of the stage IV patients was 11.1 months. The one-year survival rates of the stage IIIB and IV patients were 30.7% and 47.4%, respectively. S-1 was considered to be an active single agent against NSCLC. Further study of S-1 with other active agents is warranted.

This paper reports on data from the Regional Study of Care for the Dying, conducted in 1990, and compares symptoms, care and service utilization for patients with chronic lung diseases (CLD) and lung cancer (LC) in the final 12 months of life. Post-bereavement structured interviews were conducted with informal carers of 449 LC patients and 87 CLD patients. The LC patients were significantly younger than those with CLD (P = 0.001) and these respondents were more likely to have been a spouse (P = 0.034). No differences were found in the mean number of symptoms reported by the two groups in the final year or week of life, although the CLD patients were more likely to have experienced these symptoms for longer. Significantly more patients with CLD than LC experienced breathlessness in the final year (94% CLD vs 78% LC, P < 0.001) and final week (91% CLD vs 69% LC, P < 0.001) of life. Significantly more LC patients were reported to have experienced anorexia (76% LC vs 67% CLD, P = 0.06) and constipation (59% LC vs 44% CLD, p = 0.01) in the final year of life. There were no differences in general practitioner use, but LC patients were reported to have received more help from district nurses (52% LC vs 39% CLD, P = 0.025) and from a palliative care nurse (29% LC vs 0% CLD, P < 0.001). More CLD patients were reported to have received help from social services (29% CLD vs 18% LC, P = 0.037). LC patients were reported to be more likely to have known they might die (76% LC vs 62% CLD, P = 0.003) and to have been told this by a hospital doctor (30% LC vs 8% CLD, P = 0.001). Among those that knew, LC patients were told earlier prior to death than CLD patients. This study suggests that patients with CLD at the end of life have physical and psychosocial needs at least as severe as patients with lung cancer.

Leptin is an anorexia inductor peptide produced by adipocytes and related to fat mass. Leptin is also produced by fat under proinflammatory cytokine action. Our objective is to study serum leptin levels in relation to nutritional status and acute phase response in advanced-stage non-small cell lung cancer.Seventy-six patients newly diagnosed of non surgical non-small cell lung cancer before chemotherapy treatment and 30 healthy controls were included. BMI, serum leptin and cholesterol levels and lymphocyte count were decreased in lung cancer patients. Cytokine IL-6, TNF-alpha, sTNF-RII, sIL-2R, IL-12, IL-10 and IFN-gamma, and other acute phase reactants as alpha1 antitrypsin, ferritin, CRP and platelets were all raised in patients, whereas the IL-2 was decreased. We found a direct relationship between leptin and other indicators of the status of nutrition, especially total fat mass. We also found a close relationship between the status of nutrition and the performance status (Karnofsky index). However, serum leptin and nutritional status were inversely correlated with acute phase proteins and proinflammatory cytokines, suggesting a stress-type malnutrition. Although serum leptin levels, nutritional status and Karnofsky index are related to survival, at multivariate analysis they all were displaced by the acute phase reaction markers. These results suggest that cancer anorexia and cachexia are not due to a dysregulation of leptin production. Circulating leptin concentrations are not elevated in weight-losing cancer patients and are inversely related to the intensity of the inflammatory response. In advanced lung cancer patients serum leptin concentrations only depend on the total amount of fat.

A phase I study of gemcitabine (GEM) and docetaxel (TXT) combination chemotherapy was performed for unresectable non-small-cell lung cancer. Chemotherapy consisted of a fixed dose of GEM (1,000 mg/m2) on day 1, 8 and an escalated dose of TXT (50, 60, 70 mg/m2) on day 8 every 21 days, > or = 2 courses. Nine patients were entered (each dose level: 3 patients). Leukopenia, neutropenia, GOT increase, GPT increase, anorexia, fatigue, fever, and alopecia occurred, but no dose-limiting toxicity was found at any dose level and no MTD was reached. The recommended dose for the phase II study is GEM 1,000 mg/m2 and TXT 70 mg/m2 with consideration of application to outpatients and continuing courses.

In lung cancer patients, hypercalcemia is a fairly common metabolic problem associated with malignancy. However, the occurrence of hypercalcemia in lung cancer patients means an ominous prognostic sign. As hypercalcemia often causes early death, quick diagnosis and treatment for hypercalcemia are required. A 69-year-old woman was admitted to our hospital with anorexia caused by hypercalcemia. On admission, serum level of PTH was elevated and PTHrP was normal. From the results of CT findings and transbronchial lung biopsy, the cause of the hypercalcemia was determined as lung cancer incidentally complicated with primary hyperparathyroidism. First, serum calcium level was returned to normal through hydration with saline and bisphosphonates. Next, left hemithyroidectomy for primary hyperparathyroidism was performed. Histologically, the tumor was diagnosed as parathyroid adenoma. Fifteen days later, left lower lobectomy for primary lung cancer was performed under a video-assisted thoracoscopic approach. Histologically, the tumor was diagnosed as a moderately differentiated adenocarcinoma. Four years and three months after the operation, the patient is alive and well with no sign of recurrence. When a lung cancer patient is complicated with hypercalcemia, we need to consider that primary hyperparathyroidism is a possible cause of the hypercalcemia.
