Twelve previously untreated patients with small cell lung carcinoma (SCLC) were treated with r-interferon-gamma (Immuneron, Biogen S.A., Geneva, Switzerland). The planned dose was 1 mg (28 X 10(6) mu)/ms daily for 5 days, followed by 0.5 mg/m2 three times a week for 3 weeks or until progression, whichever was first. Eight patients were fully evaluable, and there were no responses. In four of the eight, the disease remained stable for 1 month, and four progressed before this time. Toxic reactions included pyrexia, headache, and malaise, which were mild to moderate. Ten patients subsequently received conventional chemotherapy, which resulted in three complete and four partial responses. The mean duration of response to chemotherapy was 8 months. It is concluded that r-interferon-gamma, at the dose and schedule used, has no significant clinical activity in small cell lung carcinoma.

The combination of Interferon and low-dose cyclophosphamide synergistically inhibits the growth of human breast cancer xenografts, explanted human non-small cell lung carcinoma, and other experimental tumors. To determine whether this combination would demonstrate clinical efficacy against refractory solid tumors, we used recombinant alpha-2b-Interferon, 10 MU/m2 subcutaneously three times per week, and cyclophosphamide, 25 mg orally twice daily, in 42 patients (25 renal cell carcinoma, 17 melanoma). Two patients were inevaluable due to premature removal from the study. The toxicity profile did not differ substantially from that of Interferon alone with malaise, fatigue, fevers, and chills predominating. Sixteen percent of patients experienced an alteration in mental status. Of 40 patients evaluable for response, there were two partial responders (one renal cell carcinoma, one melanoma) and four minor responders (all renal cell carcinoma). The responder with melanoma had previously failed therapy with dacarbazine (DTIC). Seventeen patients remained stable for a median follow-up of 6 months. We conclude that this regimen is well tolerated; however, the combination of Interferon and low-dose cyclophosphamide used in this way does not appear to be superior to the same dose and schedule of Interferon used alone.

Tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide, TCAR, Riboxamide, NSC 286193) is a novel C-nucleoside with antitumor activity against several murine tumor models, including Lewis lung carcinoma. The mechanism whereby this compound exerts its antineoplastic effects is most likely related to a state of guanine nucleotide depletion whereby the anabolite, thiazole-4-carboxamide adenine dinucleotide, potently inhibits inosine-5'-monophosphate dehydrogenase. This Phase I study was designed to determine the maximally tolerated dose of Tiazofurin administered on a 5-day, every-28-day schedule. Tiazofurin levels were measured using a high-pressure liquid chromatography assay, and pharmacokinetic studies were performed in patients treated at each dose level. Nineteen patients received a total of 24 courses of the drug in doses ranging from 550 to 2200 mg/sq m. The dose-limiting toxicities were pleuropericarditis and a general illness best described as a "viral-like" syndrome (manifested by severe malaise, headaches, myalgias, fever, nausea, vomiting, and diarrhea). Other toxicity included myelosuppression, hyperuricemia, elevated serum creatine phosphokinase and serum glutamic oxaloacetic transaminase, conjunctivitis, mucositis, and desquamation of the palms of the hands. Plasma clearance of Tiazofurin followed a biexponential pattern with a harmonic mean terminal half-life of 7.6 h. The mean volume of distribution at steady state was 30 liters/sq m, and the mean plasma clearance was 3 liters/h/sq m. The total cumulative urinary excretion ranged from 15 to 49%. The maximally tolerated dose of Tiazofurin on a 5-day schedule was 1650 mg/sq m. The recommended dose for Phase II evaluations is 1100 mg/sq m for 5 days. However, exploration of other schedules which might allow administration of more Tiazofurin combined with biochemical studies including thiazole-4-carboxamide adenine dinucleotide measurements would be desirable.

Thirty-eight patients with advanced measurable non-small cell carcinoma of the lung (20 adenocarcinoma, 13 epidermoid carcinoma, 5 large cell anaplastic carcinoma) were treated with alpha(leukocyte)-interferon. Patients received 3 X 10(6) units intramuscularly 5 days out of 7. Patients were treated for 12 weeks or as modified for disease progression or positive response to therapy. In 37 patients evaluable for response, one partial response was observed (adenocarcinoma). Toxicity included fever and malaise, leukopenia, thrombocytopenia, nausea-vomiting, and hepatic toxicity. One additional patient with previous cardiac and pulmonary disease had a cardiorespiratory arrest several hours after his first interferon injection. The relationship between those events is not clear. As administered, alpha-interferon showed no meaningful activity as therapy for non-small cell carcinoma of the lung.

A multi-institutional cooperative group trial was undertaken by the Cancer and Leukemia Group B (CALGB) to evaluate the efficacy of the combination of cisplatin and intravenous etoposide for the treatment of metastatic or recurrent non-small cell lung cancer (NSCLC). The doses used were those previously determined to be the maximally tolerated dose of this drug combination. Forty patients were entered into the trial, 37 of whom were eligible for evaluation. Cisplatin (35 mg/M2/day for 3 days) and etoposide (200 mg/M2/day for 3 days) were administered every 28 days for a planned 6 cycles of therapy. Sixteen of 37 evaluable patients (43%) responded to therapy. Myelosuppression was the dominant toxicity, with 89% of the patients experiencing grade 4 neutropenia, and nearly half grade 3 or 4 thrombocytopenia. Median survival was 8.5 months, with 30% of the patients alive at 1 year and 10% alive at 2 years. Malaise, fatigue, and peripheral neuropathy were the other major toxicities. The combination of etoposide at the dose of 200 mg/M2/day for 3 days and cisplatin at 35 mg/M2/day for 3 days is a highly potent combination against metastatic non-small cell carcinoma.

We conducted a randomized phase II trial of two different schedules of topotecan in patients with advanced-stage non small lung cancer (NSCLC) without prior cytotoxic chemotherapy. All patients had histologic or cytologic confirmation of stage IV (M1) or III-B NSCLC. Patients were stratified by performance status, stage and weight loss. Patients were randomized to receive topotecan at intravenous doses of 1.5 mg/m(2)/day over 30 min for 5 days every 3 weeks (Arm A) or 1.3 mg/m(2)grade 3 in both arms included leukopenia, thrombocytopenia, malaise, constipation, diarrhea, lethargy, pulmonary, vomiting, infection and myalgia. Severe (> or = grade 3) thrombocytopenia occurred in 15.8% of Arm A patients and 37.8% of Arm B patients and this difference was statistically significant (P=0.03). The median times to progression are 101 and 63 days (P=0. 75) and the median survival times are 257 and 179 days (P=0.83) for Arms A and B, respectively. These differences in time to progression and overall survival are not statistically significant. Topotecan has limited, single agent activity in advanced NSCLC when given as 1. 5 mg/m(2)/day over 30 min for 5 days every 3 weeks. We do not intend to pursue further investigations with topotecan in patients with NSCLC.

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.

A 53-year-old woman diagnosed with small-cell lung carcinoma (SCLC) was referred to our hospital because of general malaise and inappetence. Serum amylase levels were drastically elevated at 13,920 IU/l, with the salivary type dominating. She suffered multiple liver metastases and presented with disseminated intravascular coagulation (DIC). She succumbed to progressive malaise one month after admission. The amylase level was increased to 18,630 IU/l just before her death. Necropsy of the right supraclavicular lymph node confirmed SCLC with partial necrosis. Immunohistological analysis revealed that the SCLC produced salivary-type amylase. A rare case of salivary-type amylase-producing SCLC with a futile outcome was reported with review of the previous literature.

A 72-year-old man presented with weight loss, fever, and malaise. Chest radiograph and CT revealed two large ill-defined masses in middle and left lower lobes. CT-guided biopsy of left lower lobe mass disclosed bronchus-associated lymphoid tissue (BALT) lymphoma. Middle lobe mass was considered second deposit in contralateral lung. The patient received chemotherapy for BALT. Followup CT disclosed regression of left lower lobe mass and stability of middle-lobe mass and of right paratracheal lymph nodes. CT-guided biopsy of middle-lobe mass revealed squamous cell lung carcinoma. Surgical biopsy of right paratracheal lymph nodes revealed malignancy. Disease was staged T3, N2, and M0. Combined chemotherapy for lung cancer and BALT lymphoma was initiated.

A 75-year-old man presented with a non-resolving pneumonia, malaise and weight loss. His medical history included a squamous cell carcinoma of the larynx and a non-small cell carcinoma of the lung. Chest CT showed right lower lobe collapse and consolidation. Bronchoscopy identified a foreign body in the right main bronchus and was subsequently removed with rigid bronchoscope. The removed foreign body was identified as a Blom-Singer speaking valve which had been aspirated 3 months previously. This is a rare complication of a speaking valve aspiration. This case illustrates the potential differential diagnoses of retained foreign bodies in the lung and that the symptoms can mimic neoplastic disease. Once removed, patients can have a dramatic improvement in quality of life and it is important to remember that a speaking valve may be aspirated, even if one present on the initial examination!
