The symptomatic effects of oxygen on the dyspnea of terminally ill cancer patients have not been clearly established. Therefore, the decision to administer oxygen is frequently made on an individual basis. We report on the use of N of 1 randomized clinical trial to compare the symptomatic benefit of respiratory failure due to terminal ovarian cancer. A 53-yr-old female patient underwent 6 randomized double-blind crossover trials between oxygen 5 L/min delivered by mask and air 5 L/min delivered by mask. Each treatment period lasted 5 min. The mean saturation of oxygen during the baseline period was 84% +/- 3%, versus 84% +/- 4% on air (P,NS) and 94% +/- 4% on oxygen (P less than 0.001). The mean visual analogue scale (VAS) for dyspnea was 77 +/- 4 during the baseline period as compared to 51 +/- 7 after air (P less than 0.001), and 40 +/- 5 after oxygen (P less than 0.001). The patient and the investigator chose oxygen blindly in 5 of 5 cases, air in 0 and 1 case, and no choice was made in 1 and 0 case, respectively. In 4 cases the patient considered the difference between oxygen and air to be of "much importance," and in one case to be of "moderate importance." No significant treatment, period, or interaction between period and treatment was detected for the difference in the VAS. We conclude that oxygen was significantly better than air for symptomatic improvement in this patient. The N of 1 technique is a simple and reliable method for the assessment of individual patients' response to oxygen.

Adoptive immunotherapy involving bolus-dose recombinant interleukin-2 (rIL-2) has been reported to induce tumor regression in some patients with cancer, but has been associated with severe fluid retention and cardiopulmonary stress. In an effort to preserve the efficacy but reduce the toxicity of this treatment, we used escalating doses of rIL-2 as a constant infusion rather than as a bolus dose. Forty-eight patients with advanced cancer received rIL-2 as a 24-hour infusion in five-day cycles separated by five-day periods of rest and leukapheresis. Eight patients were removed from the study before receiving cells activated in vitro. In the 40 who could be evaluated for their response, there were 13 partial responses (32.5 percent) and 2 minor responses. Partial responses were observed in Hodgkin's disease (one of one), non-Hodgkin's lymphoma (one of one), lung cancer (one of five), ovarian cancer (one of one), parotid cancer (one of two), renal cancer (three of six), and melanoma (five of ten). Responses were associated with a good performance status, a base-line lymphocyte count above 1400 per cubic millimeter, and an rIL-2-induced lymphocyte count of at least 6000. Optimal lymphocytosis required a priming dose of rIL-2 of 3 X 10(6) U per square meter of body-surface area per day, and 15 of 28 patients receiving this priming dose responded to treatment. A weight gain of more than 10 percent of total body weight (five patients) and dyspnea at rest (six patients) were unusual events restricted to patients with poorer pretreatment performance. We conclude that the administration of rIL-2 as a constant infusion may preserve the antineoplastic activity of adoptive immunotherapy while increasing the safety and comfort of patients.

Linear analogue self-assessment (LASA) scales were used to measure general well-being and specific factors (mood, pain, nausea and vomiting, appetite, breathlessness, physical activity) in patients receiving therapy for malignant melanoma, small cell bronchogenic carcinoma (SCBC) or ovarian cancer. Among the patients with SCBC and melanoma, high correlations were observed between LASA scores for general well-being, mood and appetite. There was a significant relationship between performance status and LASA scores for general well-being, pain and appetite. Among patients with ovarian cancer, there was a significant association between performance status and LASA scores for general well-being, breathlessness and physical activity. Objective response category was related to change in LASA scores for pain. Changes in LASA scores during treatment reflected increased morbidity during radiotherapy in patients also receiving chemotherapy for SCBC. The LASA technique provides a convenient method for the assessment of quality of life in patients receiving cancer therapy, and potentially allows comparison of patient perception of treatment-related morbidities.

In a non-randomized clinical trial, combined intraperitoneal therapy with recombinant interferon alpha-2b (20-50 MU) and mitoxantrone (20-50 mg) was studied for recurrent ovarian cancer with ascites. Altogether 19 patients were treated. After primary operation, all patients had received intravenous chemotherapy, 16 of which included cisplatin. One patient had complete response, seven patients partial response, four no change and seven progressive disease. The mean duration of the responses was 5+ months (range 1-12), and mean survival time 4.5+ months (range 1-14+). Eight patients had side effects (flu-like symptoms, dyspnea, abdominal pain, vomiting, diarrhea, fever and bowel obstruction). It was concluded that the formation of ascites in refractory ovarian cancer can be reduced with intraperitoneal administration of interferon alpha-2b and mitoxantrone, with tolerable side effects.

An early phase II cooperative study of Gemcitabine Hydrochloride (abbreviated to "gemcitabine" herewith) was conducted in patients with a variety of solid tumors (i.e., lung cancer, gastric cancer, pancreatic cancer, colon/rectum cancer, cervical cancer, ovarian cancer and breast cancer) at 56 institutions. The aim of the first step (Step I) was to investigate the feasibility of gemcitabine in a variety of different solid tumors, including lung cancer regarding efficacy and safety. The aim of the second step (Step II) was as a result of step I (Responses were observed) to continue to investigate the efficacy and safety of gemcitabine in chemonaive patients with non-small cell lung cancer. As a Step I study, gemcitabine was administered once weekly at a dose of 800 mg/m2 for a consecutive 3-week period followed by a week of rest, in multiple courses. Among the 29 eligible patients with lung cancer, partial response (PR) was achieved in 3 patients (25.0%, 95% confidence interval: 5.5-57.2%) out of 12 chemonaive patients. Adverse reactions (grade 3 or higher) seen in 29 patients with lung cancer were neutropenia (27.6%), leukopenia (13.8%), decreased hemoglobin (13.8%), thrombocytopenia (10.3%), malaise (6.9%), anorexia (3.4%), nausea/vomiting (3.4%), diarrhea (3.4%), dyspnea (3.4%) and interstitial pneumonia (3.4%). In other types of solid tumors, PR was achieved in 2 (8.7%) out of 23 eligible patients with cervical cancer and in 1 (5.3%) of 19 eligible patients with ovarian cancer, while the use of analgesics became unnecessary in 1 patient with pancreatic cancer. Incidence as well as severity of main adverse reactions in these patients were comparable to those seen in patients with lung cancer. A Step II study, in which gemcitabine was administered once weekly at a dose of 1,000 mg/m2 to chemonaive patients with non-small cell lung cancer, was conducted, referring to the results of Step I and clinical studies conducted overseas. The results of the Step II study demonstrated PR in 5 (14.3%, 95% confidence interval: 4.8 - 30.3%) out of 35 eligible patients with non-small cell lung cancer and that the main adverse reactions were comparable to those seen in the Step I study, posing no tolerability problems in particular.

Two patients with ovarian cancer who had received multiple courses of cisplatin without complications experienced hypersensitivity reactions to cisplatin: one, involving intrahepatic artery infusion, manifested general erythema, dyspnea, and hypotension; the other, involving intravenous infusion, manifested abdominal pain, general erythema, and fever. When platinum-containing agents are administered, patients should be closely monitored for hypersensitivity reactions, even in previously uncomplicated cases.

About 50% of the pleural effusions diagnosed are caused by a malignancy, especially by thoracic, pulmonary and ovarian cancer and lymphomas. The accumulation of fluid is caused by metastasization to the pleura and obstruction of lymph vessels and nodes. The effusion generally decreases if the tumour responds to systemic treatment. However, frequently this does not occur and the fluid has to be removed, to alleviate symptoms such as dyspnoea, coughing and a heavy sensation in the chest. Possible surgical therapies are draining through a needle or a drain, (partial) pleural resection and the creation of a pleuro-peritoneal shunt. Disadvantages of these are early recurrences, the severity of the intervention and (or) the high morbidity and mortality. The current standard treatment is pleurodesis brought about by a sclerosing agent, usually via a drain. The substances preferably used for this purpose are, in the order of decreasing importance, tetracycline, bleomycin or talc, doxycycline or minocycline. The most frequent adverse effects are chest pain and fever during and after the pleurodesis.

CI-980 is a synthetic mitotic inhibitor that binds to tubulin at the colchicine site, inhibiting the polymerization of microtubules and arresting cellular division in metaphase. Myelosuppression and neurotoxicity were dose-limiting in phase I studies. Sixteen patients with stage III and IV platinum-refractory ovarian cancer received 4.5 mg/m2/day of CI-980 as a continuous i.v. infusion for 72 h, repeated every 3 weeks. Eleven patients had progression and four patients had stable disease. One patient (6%; 95% CI 0-25%) achieved a partial response after 9 months of treatment which lasted for 27 months. The overall median survival was 7 months. Grade 4 granulocytopenia occurred in five patients, with two episodes of neutropenic fever. Neurological toxicity was mild with 12 episodes of transient subclinical recent memory loss documented in four patients by specialized neuropsychological evaluations. One patient each had hallucinations and mild truncal ataxia, and four patients had mild, reversible neurosensory toxicity. One episode of severe hypoxemia and dyspnea occurred in a patient with chronic obstructive pulmonary disease. CI-980 has minimal activity and is tolerable in a population of heavily pretreated patients with platinum refractory ovarian cancer.

Oncologic emergencies have been extensively described and clearly defined. In oncology daily practice, cancer patients seek non-scheduled medical care in situations they perceive as a medical emergency, but which may not be a true emergency. The aim of the study was to identify the main symptoms leading to a non-scheduled consultation (NSC) and their relationship to the type of cancer, and to evaluate whether the diagnosis at discharge of patients admitted as result of a NSC correlates with a true oncologic emergency. This was a prospective observational study. Between July 2002 and April 2003, 365 NSCs were recorded. The most frequent baseline diseases were breast cancer (70), lung cancer (67), gastrointestinal cancer (52), lymphoma (42) and ovarian cancer (22). The most common symptoms for consultation were: fever (84), pain (81), cutaneous manifestations (26), dyspnea (23), bleeding (16) and abdominal distention (16). Overall, 114 of 365 NSCs (31%) resulted in admission. The most frequent symptoms resulting in admission were fever (42), pain (16), dyspnea (11), vomiting (9), neurologic manifestations (7), abdominal distention (6) and anuria (6). At discharge, only 30 patients (26%) admitted after a NSC were diagnosed with a defined oncologic emergency: febrile neutropenia (13), intestinal occlusion (12), obstructive uropathy (4) and abdominal perforation (1). True emergencies were not the most frequent causes of NSC at our institution.

The objectives were to define the incidence, risk factors, clinical features and outcome of arterial desaturation syndrome following talc pleurodesis in patients with malignant pleural effusions. This retrospective, observational study took place at a tertiary care cancer center in New York. All patients were those with malignancy who underwent pleurodesis with talc in 1998 at Memorial Sloan Kettering Cancer Center. Characteristics of patients are described by using summary statistics. Differences between groups were assessed with the Fisher's exact statistic for categorical variables and Student's t-test for continuous variables. Among patients who were considered to have arterial desaturation syndrome, we evaluated the relation of SaO2/FIO2 pre- and post-talc installation using a paired Student's t-test. During 1998, 120 patients underwent pleurodesis with talc, and 8 (7%) developed arterial desaturation following the procedure. Symptoms included chest pain, dyspnea, fever, and increased need for oxygen supplementation developed typically within 1 day. Three of the eight patients in this series required mechanical ventilation, but all recovered uneventfully after treatment, which included high-dose corticosteroids. Patients with breast and ovarian cancer appeared to be at increased risk for this complication compared to those patients with other types of cancer (p = 0.01). Approximately 7% of patients who have undergone sclerosis with talc for a malignant pleural effusion will develop arterial desaturation with clinically significant hypoxia requiring supplemental oxygen following the procedure. It appears that most patients recover from this complication and that those with breast and ovarian cancer may be at higher risk.
