R N Hitchins; David Bell; R L Woods; John A. Levi

Forty-four patients with documented meningeal carcinomatosis (small-cell lung carcinoma [SCLC], 29%; breast carcinoma, 25%) were treated in a prospective randomized trial with intrathecal methotrexate (MTX) 15 mg or MTX plus cytosine arabinoside (Ara-C) 50 mg/m2. Most patients received intrathecal hydrocortisone (HC) each treatment to minimize arachnoiditis. Overall response was 55%. Seven patients achieved complete response. Response to MTX was superior to combined MTX/Ara-C, but not significantly so (61% v 45%; P greater than .10). Response was more frequent if drugs were administered via Ommaya reservoir than by lumbar puncture (65% v 48%; P greater than .10). Concurrent radiotherapy to the CNS was associated with significantly better response (73% v 35%; P less than .05). Small-cell lung carcinoma patients showed the best response (69%). Overall median survival for the whole group was 8 weeks, but responders fared better than nonresponders (median survival, 18 v 7 weeks; P less than .05). Nausea and vomiting were the most common toxicities encountered (45%), but rarely proved limiting. An unusual, previously undocumented reaction to intrathecal HC was noted. MTX is moderately effective in nonleukemic meningeal carcinomatosis, but the addition of Ara-C does not appear to improve results. Pretreatment factors did not predict outcome in this trial.

PURPOSE To determine the place of single-agent paclitaxel compared with nonanthracycline combination chemotherapy as front-line therapy in metastatic breast cancer. PATIENTS AND METHODS Patients with previously untreated metastatic breast cancer were randomized to receive either paclitaxel 200 mg/m(2) intravenously (IV) over 3 hours for eight cycles (24 weeks) or standard cyclophosphamide 100 mg/m(2)/d orally on days 1 to 14, methotrexate 40 mg/m(2) IV on days 1 and 8, fluorouracil 600 mg/m(2) IV on days 1 and 8, and prednisone 40 mg/m(2)/d orally on days 1 to 14 (CMFP) for six cycles (24 weeks) with epirubicin recommended as second-line therapy. RESULTS A total of 209 eligible patients were randomized with a median survival duration of 17.3 months for paclitaxel and 13.9 months for CMFP. Multivariate analysis showed that patients who received paclitaxel survived significantly longer than those who received CMFP (P =.025). Paclitaxel produced significantly less severe leukopenia, thrombocytopenia, mucositis, documented infections (all P <.001), nausea or vomiting (P =.003), and fever without documented infection (P =.007), and less hospitalization for febrile neutropenia than did CMFP (P =.001). Alopecia, peripheral neuropathy, and myalgia or arthralgia were more severe with paclitaxel (all P <.0001). Overall, quality of life was similar for both treatments (P > = .07). CONCLUSION Initial paclitaxel was associated with significantly less myelosuppression and fewer infections, with longer survival and similar quality of life and control of metastatic breast cancer compared with CMFP.

The value of chemotherapy in advanced non-small cell lung cancer (NSCLC) remains contentious. Because of this two separate but very similar trials were set up in Australia and Southampton (UK). Two hundred and one patients with stage IIIb or IV NSCLC were randomly assigned to cisplatin 120 mg m-2 on days 1 and 29 and vindesine 3 mg m-2 weekly x 6 or to no chemotherapy. Both groups were eligible to receive radiotherapy or other palliative treatment as required. Of 188 evaluable patients, 97 received chemotherapy and 91 were in the control arm. Response was assessed between days 42 and 49. Responders continued chemotherapy at the same doses though cisplatin being given 6 weekly x 4 and the vindesine 2 weekly x 12. The overall response rate to chemotherapy was 28%; there were no significant differences according to major prognostic criteria. Although the overall survival of the chemotherapy group (median 27 weeks) was longer than that of the no chemotherapy group (median 17 weeks) this was not statistically significant (log rank P = 0.33). For patients without dissemination (IIIb), median survival was 45 weeks in the chemotherapy arm and 26 weeks in the non-chemotherapy (log rank P = 0.075). Toxicity was universal and frequently severe: of 17 patients discontinuing chemotherapy after one cycle, 13 did so because of unacceptable toxicity. This chemotherapy cannot be recommended as routine treatment. Further phase III studies of chemotherapy in advanced NSCLC should continue to use a no chemotherapy control and should also attempt to measure quality of life, an issue not addressed effectively in this or other recent trials.

Treatment options and prognosis remains poor for patients with recurrent glioblastoma multiforme. These tumors are highly vascularised and over express angiogenic factors such as vascular endothelial growth factor and may potentially be responsive to antiangiogenic therapies. We present the results of a phase II trial of Thalidomide, an antiangiogenic agent, in the treatment of recurrent glioblastoma multiforme. Patients were treated with 100 mg/day of Thalidomide, increased at weekly intervals by 100 mg to a maximum tolerated dose of 500 mg/d.Forty-two patients were enrolled, with 38 patients being assessable for response and 39 for toxicity. Two patients (5%) achieved a partial response and 16 (42%) had stable disease. The median survival was 31 weeks and the 1-year survival was 35%. Patients who had a partial response or stable disease had either a stabilisation or improvement in quality of life scores or performance status. Overall Thalidomide was well tolerated with no grade 4 toxicities and no treatment related deaths. The median maximum tolerated dose was 300 mg/day. The most common toxicity was fatigue to which patients developed tachyphylaxis. There was no correlation demonstrated with plasma vascular endothelial growth factor levels and response or survival.Thalidomide is a well-tolerated drug that may have some activity in the treatment of recurrent glioblastoma. Optimum dosing with antiangiogenic agents is currently under investigation. Chronic low dose therapy may be required to see conventional responses or improvements in time to progression. The dose required to achieve optimal biological impact may be better defined once we have established reliable surrogate endpoints.

PURPOSE In an effort to maintain the excellent long-term results achieved with combination chemotherapy for good-prognosis germ cell carcinoma, but to reduce the toxicities encountered, a randomized trial was conducted comparing cisplatin and vinblastine with or without bleomycin. PATIENTS AND METHODS Two hundred eighteen assessable patients with a good prognosis were randomized to receive induction chemotherapy with cisplatin 100 mg/m2 intravenously (IV) day 1 and vinblastine 6 mg/m2 IV days 1 and 2 every 3 weeks (PV) with or without bleomycin 30 mg intramuscularly (IM) weekly (PVB) for a maximum of 12 weeks. Once maximum response was achieved, patients with a complete remission (CR) received two courses of consolidation chemotherapy, while those with residual abnormalities and normal tumor markers underwent surgical resection whenever possible. RESULTS Toxicities encountered in this study were clearly greater for those patients who received bleomycin, with significantly more leukopenia, thrombocytopenia, anemia, alopecia, and renal and pulmonary toxicities. The proportion of patients who achieved CR and had no evidence of disease (resection of all viable malignancy) was 89% for PV and 94% for PVB (P = .29). After a minimum of 4 years of follow-up, relapses have occurred in 7% of patients who received PV and 5% who received PVB. A total of five patients on each therapy arm were successfully treated with further salvage chemotherapy and surgery. Thus, deaths from progressive malignancy have occurred in 15% of patients on PV and 5% on PVB (P = .02), a rate that was partly offset by the higher proportion of toxic deaths with PVB (P = .06). CONCLUSION Despite the toxicities encountered with bleomycin in cisplatin-based combination chemotherapy for these patients, complete deletion of this drug compromises therapeutic efficacy.

BACKGROUND Most patients with metastatic germ-cell tumours are cured with chemotherapy. However, the optimum chemotherapy regimen is uncertain, and there is variation in international practice. We did a multicentre randomised trial to compare two standard chemotherapy regimens for men with good-prognosis germ-cell tumours. METHODS Good prognosis was defined by modified Memorial Sloan-Kettering criteria. The first regimen (regimen A) was based on treatment recommendations from Indiana University and comprised three cycles of 20 mg/m2 cisplatin on days 1-5, 100 mg/m2 etoposide on days 1-5, and 30 kU bleomycin on days 1, 8, and 15, repeated every 21 days. The second regimen (regimen B) was based on the control regimen of a published randomised clinical trial and comprised four cycles of 100 mg/m2 cisplatin on day 1, 120 mg/m2 etoposide on days 1-3, and 30 kU bleomycin on day 1, repeated every 21 days. The primary outcome measure was overall survival. Analysis was by intention to treat. FINDINGS 166 patients were randomised, 83 to each regimen. The trial was stopped when the second planned interim analysis met predefined stopping rules. The median follow-up was 33 months. Overall survival was substantially better with regimen A (three vs 13 deaths, hazard ratio 0.22 [95% CI 0.06-0.77], p=0.008). This difference was due to deaths from cancer (one vs nine), and not deaths from treatment (two vs two) and remained significant after adjustment for other prognostic factors (0.25 [0.07-0.88], p=0.03). INTERPRETATION In men with good-prognosis germ-cell tumours, the regimen developed at Indiana University is superior to the alternative regimen studied in this trial. The lower total dose and dose-intensity of bleomycin and the lower dose-intensity of etoposide in regimen B could be responsible for the worse outcome.

Management of mycosis fungoides--current status and future prospects.

John A. Levi; Peter H. Wiernik

Current knowledge concerning the course of mycosis fungoides and recognized prognostic factors have been reviewed. Those factors with prognostic significance at the time of biopsy diagnosis include age and the clinical findings of skin tumors, ulceration or palpable lymphadenopathy. During the course of disease, the development of skin tumors, ulceration or palpable lymphadenopathy were each associated with a poor prognosis and median survival was only 12 months if all those clinical parameters were present. Patients who developed overt visceral mycosis fungoides rarely survived more than a few months. Lymphocytopenia and the presence of malignant lymphoma in biopsied lymph nodes were also poor prognostic findings. The various modalities of therapy for proven mycosis fungoides were reviewed. Topical therapy and external irradiation were generally of symptomatic benefit only, but two recent studies have shown that aggressive use of topical nitrogen mustard and electron beam therapy are associated with long-term responses in patients with disease confined to the skin. Single agent chemotherapy often resulted in transient responses in advanced and refractory mycosis fungoides. Future approaches to the management of mycosis fungoides have been suggested. These include a thorough review of the histological features, a thorough and systematic pretreatment evaluation and randomized studies of the various treatment modalities including combination therapy in appropriately staged patients.

The predictive value of body protein for chemotherapy-induced toxicity.

Alireza Aslani; Ross C. Smith; Barry J. Allen; Nick Pavlakis; John A. Levi

The use of body surface area in determining chemotherapy dosing, particularly in the obese, remains controversial. Total body nitrogen (TBN) measurement in patients with serious illness has been suggested to be an accurate predictor of clinical course. The ability of TBN to predict chemotherapy‐induced neutropenia was examined in the current study.

Changes in body composition during breast cancer chemotherapy with the CMF-regimen.

Alireza Aslani; Ross C. Smith; Barry J. Allen; Nick Pavlakis; John A. Levi

Weight gain is a reported problem associated with adjuvant chemotherapy for breast cancer and often generates psychosocial stress in women [1]. It also may affect prognosis and survival. Changes in body composition and weight during chemotherapy, particularly adjuvant treatment of breast carcinoma, have been previously reported [1–3]. Multiple reasons for this weight gain have been suggested though few theories have been scientifically validated [4].The aim of this study was to investigate body composition and its relationship to weight change associated with the CMF‐based breast cancer chemotherapy protocols. Total body nitrogen (TBN), body fat, total body water (TBW), and anthropometric measurements were conducted on 25 female out‐patients (median age 47, range 26–70 years) receiving adjuvant CMF‐based chemotherapy for breast cancer. Total body nitrogen was measured using the In Vivo Neutron Capture Analysis (IVNCA) technique (on day 1 of cycles 2–6) and TBP was calculated by multiplying TBN by 6.25 [5]. Nitrogen Index (NI) was calculated by expressing TBN as a percentage of normal.There was a significant increase in mean body weight during chemotherapy of 2.35 kg (p<0.0001). Serial measurements showed no significant change in mean TBN, NI, or percentage body fat. Break down of body weight showed a significant increase in mean TBW of 0.79 kg (p=0.003) and mean fat mass of 1.49 kg (p=0.008).We conclude that weight gain observed during adjuvant chemotherapy for breast carcinoma is primarily due to an increase in fat and TBW.
