Abstract
3049 Background: Preclinical models of combination angiogenesis inhibitor bevacizumab (rhuMAbVEGF) and docetaxel demonstrate synergistic suppression of capillary vessel formation. Based upon these data, we developed a randomized phase II trial in order to evaluate the vascular effects on tumor regression with combination bevacizumab/docetaxel vs. docetaxel in the treatment of locally advanced breast cancer. Methods: 49 patients (pts) were randomized to receive neoadjuvant therapy with bevacizumab (10 mg/kg qowk) and docetaxel (two 8-week cycles of 35 mg/m2 weekly x 6 with a 2 wk break) (BD=24) or docetaxel (D=25) alone. Eligible pts had locally unresectable breast cancer with (n=6) or without distant metastasis (n=43); 16 patients presented with inflammatory breast cancer. Pts whose disease responded, sequentially underwent definitive surgery (4 weeks after BD or D), radiation, 4 cycles of conventional Adriamycin/cyclophosphamide, and tamoxifen or anastrazole (if ER/PR+). Results: Among the 49 pts: 7 clinical CRs, 32 PRs, 5 NR, and 5 PD. Of the 37 pts who underwent surgery: the median number of pathologically positive lymph nodes (LN) was 1 (BD=6, D=1; p=0.228); range 0–20; 43% were LN negative. Neoadjuvant treatment toxicity for both arms was acceptable with no significant differences between the two arms. Grade 4 toxicity included BD - new papillary thyroid cancer (1), neutropenia (1), hyperuricemia (1) and colon perforation (1); and D: - hyperglycemia (1) and hyperuricemia (1). 21 patients in each arm experienced a grade 3 toxicity. There were no episodes of uncontrolled hypertension, proteinuria, or thrombosis. Delayed wound healing (unable to start radiation w/in 6 weeks of surgery) occurred in 8 pts: BD=5; D=3 (p=0.691). Only 1 pt (D) experienced a change in LVEF by > 15% or below the institution’s lower limit of normal. Conclusions: Neoadjuvant therapy for locally advanced breast cancer using docetaxel with bevacizumab is well tolerated. Further studies are required to determine the added efficacy from bevacizumab. Correlative studies on impact of treatment on angiogenesis will be reported separately.

Abstract
BACKGROUND Strategies to circumvent or lessen the myelotoxicity associated with combination chemotherapy may improve the overall outcome of the management of patients particularly in resource poor settings. OBJECTIVES To develop effective non-myelotoxic therapies for Burkitt's Lymphoma (BL) and AIDS-related non-Hodgkin's lymphoma. DATA SOURCES Publications, original and review articles, conference abstracts searched mainly on Pubmed indexed for medline. DATA EXTRACTION A systematic review of the clinical problem of combination chemotherapy. Identification of clinical strategies that circumvent or lessen the myelotoxicity of combination cytotoxic chemotherapy. Length of survival, lack of clinically significant (> grade 3) myelosuppression and weight loss were used as markers of myelotoxicity. DATA SYNTHESIS Review of published experience with some of these strategies including dose-modification of multi-agent chemotherapy; rationale for targeted therapies, and the preclinical development of a mouse model exploring the role of metronomic scheduling substantiate pragmatism and feasibility of these approaches. CONCLUSION Myelotoxic death rates using multi-agent induction chemotherapy approach 25% for endemic Burkitt's lymphoma and range between 20% to 60% for AIDS-related malignancy. This is mostly explained by the paucity of supportive care compounded by wasting and inanition attributable to advanced cancer and HIV infection making patients more susceptible to myelosuppressive side effects of cytotoxic chemotherapy. Investigations and alternative approaches that lessen or circumvent myelotoxicity of traditional cytotoxic chemotherapy for the management of Burkitt's lymphoma and AIDS-related non-Hodgkin's lymphoma in the resource-constrained setting are warranted. Pertinent pre-clinical and clinical data are emerging to support the need for abrograting the myelosuppressive effects of traditional cytotoxic chemotherapy. This can be achieved by developing targeted anti-viral and other strategies, such as the use of bryostatin 1 and vincristine, and by developing a preclinical mouse model to frame the clinical rationale for a pilot trial of metronomic therapy for the treatment of Burkitt's and AIDS-related lymphoma. Implementation of these investigational approaches must be encouraged as viable anti-cancer therapeutic strategies particularly in the resource-constrained settings.

Abstract
OBJECTIVES To determine the effectiveness of an oral combination chemotherapy regimen administered to patients with AIDS-associated Hodgkin's disease. DESIGN Prospective, pilot phase II clinical trial. SETTING Consecutive patient recruitment occurred at two medical centers in the United States: Albany Medical Center, Albany, New York, where patients were recruited prior to December 31, 1996 (pre-HAART era); and University Hospitals of Cleveland, Cleveland, Ohio, where patients were recruited after January 1, 1997 (HAART era). INTERVENTION Oral chemotherapy consisted of lomustine (100 mg/m2 day I for cycle one and odd cycles thereafter); etoposide (200 mg/m2 days 1 through 3); and cyclophosphamide and procarbazine (each 100 mg/m2 days 22 through 31). Cycles were repeated every six weeks. Colony-stimulating factor support (G-CSF in all instances) was allowed. MAIN OUTCOME MEASURES Clinical demographic variables, peripheral blood counts, serum chemistries, CD4 lymphocyte count, histopathological subtype of Hodgkin's disease were identified for all patients, who were staged according to Ann Arbor criteria. DATA ANALYSIS Common Toxicity Criteria were utilized to assess safety; response was assessed using ECOG criteria; and survival was analyzed by Kaplan-Meier methods and difference of survival between pre-HAART and HARART era was compared using log-rank test. RESULTS Eleven patients (six in pre-HAART era), all but one male, with a median age of 36 years, excellent performance status and advanced International Prognostic Score were treated. Myelosuppression was the major side effect and there were minimal other grade 3 or greater toxicity all of which were promptly reversible. An overall objective response rate of 82% (with 18% complete responses) and median survival duration of 24 months (range 2.5 +/- 68) were observed. Survival was markedly improved in patients treated in the HAART era (median not reached versus 7.25 months, p = 0.034). CONCLUSIONS This feasibility study demonstrates acceptable tolerance and excellent clinical activity of oral combination chemotherapy in patients with AIDS-associated Hodgkin's disease. Improved survival is observed in combination with HAART therapy. Dose-modification of this regimen would be suitable to evaluate in the resource constrained setting and larger confirmatory studies are encouraged.

Abstract
OBJECTIVES To describe the clinical characteristics of Burkitt's lymphoma (BL) from three regions in Kenya at different altitudes with a view towards understanding the contribution of local environmental factors. DESIGN Prospective cross-sectional study. SETTING Kenyatta National Hospital and seven provincial hospitals in Kenya. METHOD Histologically proven cases of Burkitt's lymphoma in patients less than 16 years of age were clinically examined and investigated. MAIN OUTCOME MEASURES For every case the following parameters were documented: chief complaint(s); physical examination, specifically pallor, jaundice, oedema, lymphadenopathy, presence of masses, splenomegaly and hepatomegaly. Reports of evaluation of chest radiograph, abdominal ultrasound/scan, bone marrow aspiration, cerebral spinal fluid cytology, liver and kidney function tests, urinalysis, stool occult blood and full blood count results. Stage of disease was assigned A, B, C or D. Cases of BL from three provinces of Kenya with diverse geographical features were analysed: Central, Coast, and Western. RESULTS This study documented 471 BL cases distributed as follows: Central 61 (males 39 and 22 females), M:F ratio 1.8:1; Coast 169 (111 males and 58 females), M:F ratio 1.9:1; and Western 241 (140 males and 101 females), M:F ratio 1.4:1. The major presenting complaints were: abdominal swelling--Central 36%, Coast 4% and Western 26%; swelling on the face--Central 31%, Coast 81% and Western 64%; and proptosis--Central 3%, Coast 1% and Western 9%. The mean duration of these complaints in weeks were Central 6.9, Coast 6.08, and Western 5.05. The initial physical finding was a tumour mass in 39%, 72% and 54% of cases for Central, Coast and Western respectively. Tumour stage at diagnosis was: stage A--Central 21%, Coast 43% and Western 34%; stage B--Central 10%, Coast 5% and Western 10%; stage C--Central 41%, Coast 34% and Western 30%; and stage D--Central 28%, Coast 17% and Western 26%. For the age and sex matched cases the results show that commonly involved sites were: abdomen--Central 35%, Coast 9% and Western 14%; jaw (mandible)--Central 24%, Coast 22% and Western 31%; maxilla--Central 6%, Coast 24% and Western 11%; and lymph nodes--Central 10%, Coast 4% and Western 8%. The disease stage was A--Central 33%, Coast 44% and Western 36%; stage B--Central 11%, Coast 10% and Western 27%; stage C--Central 39%, Coast 34% and Western 27%; and stage D--Central 21%, Coast 13% and Western 37%. CONCLUSION This study shows that clinical features of childhood BL vary with geographical region. The variations are documented in proportion of jaw, maxilla, abdominal and lymph nodal sites involvement. The differences observed are potentially due to the local environmental factors within these provinces. BL cases from Western province had features, intermediate between endemic and sporadic. Coastal province BL cases were similar to endemic BL, while BL cases from Central province resembled more or less sporadic BL subtypes. Strategies to explain and investigate the local environmental factors associated with the observed differences may certainly contribute towards improved understanding and clinical management of BL.

Abstract
PURPOSE In the setting of target-based anticancer drug development, it is critical to establish that the observed preclinical activity can be attributed to modulation of the intended target in early phase trials in human subjects. This paradigm of target modulation allows us to determine a Phase II or III dose (optimal biochemical/biological modulatory dose) that may not necessarily be the maximum tolerated dose. A major obstacle to target-based (often cytostatic) drug development has been obtaining relevant tumor tissue during clinical trials of these novel agents for laboratory analysis of the putative marker of drug effect. EXPERIMENTAL DESIGN From 1989 to present, we have completed seven clinical trials in which the end point was a biochemical or biological modulatory dose in human tumor tissues (not surrogate tissue). Eligibility enrollment required that patients have a biopsiable lesion either with computerized tomography (CT) guidance or direct visualization and consent to sequential (pre and posttreatment) biopsies. RESULTS A total of 192 biopsies were performed in 107 patients. All but 8 patients had sequential pre and posttreatment biopsies. Seventy-eight (73%) of the 107 patients had liver lesion biopsies. In eight patients, either one or both biopsies contained insufficient viable tumor tissue or no tumor tissue at all for analysis. Of a total of 99 patients in whom we attempted to obtain paired biopsies, a total of 87 (88%) were successful. Reasons for failure included patient refusal for a second biopsy (n = 2), vasovagal reaction with first biopsy precluding a second biopsy (n = 1), subcapsular hepatic bleeding (n = 1), and most commonly obtaining necrotic tumor, fibrous, or normal tissue in one of the two sequential biopsies (n = 8). CONCLUSIONS This is the first and largest reported series demonstrating that with adequate precautions and experience, sequential tumor biopsies are feasible and safe during early phase clinical trials.

Abstract
Prior to the acquired immunodeficiency syndrome (AIDS) epidemic, one or two cases of adult Burkitt's lymphoma (BL) were seen annually at the Kenyatta National Hospital, the national referral medical center in Nairobi, Kenya. To investigate the influence of human immunodeficiency virus (HIV) infection in adult BL in Kenya, we conducted a national prevalence survey of all patients 16 years of age and older with BL. A systematic review of medical records of all patients diagnosed with BL between 1992 and 1996 was performed. The diagnosis of BL was based and confirmed on review of pathological material from time of original diagnosis. HIV serology was confirmed by enzyme-linked immunosorbent assay (ELISA). Twenty-nine adult patients with BL were identified during the 5-year study period. Of these patients, 17 (59%) were males, 12 (41%) were females, and the median age was 26 years. Nineteen patients (66%) with BL were HIV-seropositive. The proportion of men was similar in HIV-seropositive and -seronegative patients (58% vs 60%). HIV-seropositive BL patients were significantly older than seronegatives (median 35 vs 19.5 years, p < 0.001). HIV-seropositive patients uniformly presented with constitutional or B symptoms and advanced BL accompanied by diffuse lymph node involvement, whereas the clinical presentation of HIV-seronegative patients during this time period was reminiscent of the "typical" endemic pattern of disease with complete sparing of peripheral lymph nodes. The overall survival of HIV-seropositive cases was significantly worse than that of the HIV-seronegative cases; median survival in the HIV-seropositive patients was 15 weeks. There is an approximate 3-fold increase in the incidence of adult BL during the time period of this study, which is attributable to the AIDS epidemic. In this setting, patients often present with disseminated disease, diffuse peripheral lymphadenopathy and fever, the latter two of which heretofore have been commonly associated with non-lymphoproliferative disorders such as Mycobacterium tuberculosis and sexually transmitted diseases in Kenya. These observations warrant inclusion of AIDS-related BL in the differential diagnosis of the adult patient with unexplained fever and lymphadenopathy in Kenya. The corollary is that HIV infection is virtually excluded in an adult patient without peripheral lymphadenopathy and biopsy-proven BL.

Abstract
Obtaining a complete response (CR) is the most powerful predictor of survival in extensive-stage small cell lung cancer (SCLC). Improvements in long-term survival in extensive-stage SCLC can be made if the proportion of complete responders to induction therapy can be increased. We performed a phase II trial of the feasibility of adding paclitaxel to standard cisplatin/etoposide (EP regimen) in extensive-stage SCLC. The primary endpoint for this trial is the proportion of patients (pts) obtaining a CR rather than overall response. The null hypothesis for this trial consists of the absence of a CR rate >20%. Paclitaxel was given at doses of 135 (3 pts) or 170 mg/m(2) i.v. over 3 h on day 1. Cisplatin 60 mg/m(2) was given on day 1. On days 1-3 etoposide 80 mg/m(2) per day i.v. was given. G-CSF was used from days 5 to 14 of each cycle. Cycles were repeated q21 days. A two-stage design was used for patient accrual, based on the occurrence of complete responses. Initially, 16 patients were to be accrued. If more than three complete responses were to occur, a further 20 patients would be accrued to the study (Simon's optimal two stage design). Sixteen patients were enrolled. Two patients had a CR (13%) and nine patients had a partial response (56%) for an overall response rate of 69%. The trial was suspended due to the low CR rate. Review of the literature for paclitaxel based front-line treatment combined with EP therapy, in extensive stage SCLC, consistently shows a CR rate <20% but high overall response rate is maintained (thus most responses are partial). As virtually all long-term survivors in extensive-disease SCLC have had a CR to induction therapy and CR remains the strongest predictor of survival for this disease, this may suggest that paclitaxel added to standard EP may improve progression-free survival (and possibly median survival) but is unlikely to significantly improve long-term survival. Initial randomized phase III data confirm the absence of impact on survival for this triple-drug regimen compared to EP therapy alone. Furthermore, other regimens comparing favorably to the EP regimen have all shown consistent CR rates >20% in the phase II setting. In conclusion, consideration should be given to the use of CR rate as a phase II endpoint to determine if a particular regimen should be compared to the standard in a phase III setting for extensive-stage SCLC. A two-stage phase II design based on a minimum required completed responses for further patient accrual is recommended.

Abstract
PURPOSE Rebeccamycin analog (NSC 655649) is active against a variety of both solid and nonsolid tumor cell lines. We performed a phase I trial to determine the maximum-tolerated dose (MTD) of rebeccamycin analog when given on a daily x 5 schedule repeated every 3 weeks, characterize the toxicity profile using this schedule, observe patients for antitumor response, and determine the pharmacokinetics of the agent and pharmacodynamic interactions. PATIENTS AND METHODS Thirty assessable patients received a total of 153 cycles according to the following dose escalation schema: 60, 80, 106, 141, and 188 mg/m(2)/d x 5 days. RESULTS Grade 2 phlebitis occurred in all patients before the use of central venous access, placed at dose level 4 and higher. Dose-limiting toxicity (DLT), grade 4 neutropenia, occurred at 188 mg/m(2)/d x 5 days in both previously treated and chemotherapy-naive patients. Pharmacokinetic analysis revealed a three-compartmental model of drug elimination and a long terminal half-life (154 +/- 55 hours). The percentage drop in absolute neutrophil count correlates with the area under the curve infinity. The presence of a second peak during the elimination phase as well as a high concentration of NSC 655649 in biliary fluid compared with the corresponding plasma measurement (one patient) is suggestive of enterohepatic circulation. Two partial responses, two minor responses, and six prolonged (> 6 months) cases of stable disease were observed. Of these, three patients with gallbladder cancer and one patient with cholangiocarcinoma experienced either a minor response or a significant period of freedom from progression. CONCLUSION The recommended phase II dose for NSC 665649 on a daily x 5 every 3 weeks schedule is 141 and 165 mg/m(2)/d for patients with prior and no prior therapy, respectively, with DLT being neutropenia. During this phase I trial, encouraging antitumor activity was been observed.

Abstract
PURPOSE In vitro and in vivo preclinical models have demonstrated synergistic activity when topoisomerase I and II inhibitors are administered sequentially. Topoisomerase I inhibitors increase topoisomerase II levels and increase cell kill induced by topoisomerase II poisons. We evaluated this hypothesis in a cohort of patients with advanced non-small-cell lung cancer (NSCLC). METHODS A group of 19 patients with advanced NSCLC (70% adenocarcinoma) received topotecan at a dose of 0.85 mg/m2 per day as a continuous 72-h infusion from days 1 to 3. Etoposide was administered orally at a dose of 100 mg twice daily for 3 days on days 7-9 (schedule and dose derived from prior phase I trials). Total and lactone topotecan concentrations were measured at the end of the 72-h infusion. Blood samples were obtained immediately after each 72-h topotecan infusion in order to measure the mutational frequency at the hypoxanthine phosphoribosyl transferase (HPRT) locus in peripheral lymphocytes. RESULTS A total of 55 cycles were administered. Toxicity was mainly hematologic with grade 4 neutropenia occurring in 7% of courses. Only one partial response and two stable diseases were observed. The 1-year survival rate was 33%. There was a statistically significant difference between steady-state lactone concentrations between cycle 1 and cycle 2 with decreasing concentrations with cycle 2 (P = 0.02). This was explained by a statistically significant increase in the clearance of topotecan lactone during cycle 2 (P = 0.03). Total but not lactone concentrations correlated with nadir WBC, ANC and platelet levels. Steady-state plasma lactone levels correlated with the mutational frequency at the HPRT locus (P = 0.06). In the one patient with a partial response a sixfold increase in HPRT mutational frequency was observed, which was not seen in patients with progressive disease. CONCLUSION The combination of topotecan and etoposide in this schedule of administration has minimal activity in adenocarcinoma of the lung. This lack of activity may be due to the delay in administration of etoposide after the topotecan as studies have shown that the compensatory increase in topoisomerase II levels after treatment with topoisomerase I inhibitors is shortlived (<24 h). The HPRT mutational frequency results suggest that the lack of clinical response may be associated with failure to achieve sufficient cytotoxic dose as indicated by a lack of increase in mutational frequency in those patients with progressive disease. HPRT mutational frequency may correlate with plasma steady-state topotecan lactone levels. Future studies should be directed toward earlier administration of topoisomerase II inhibitors after topoisomerase I inhibition.

Abstract
BACKGROUND African Kaposi's sarcoma (KS) lesions contain human herpesvirus-8 (HHV-8) and Epstein-Barr virus (EBV), both of which are associated with various types of non-Hodgkin's lymphomas and are known to produce several factors suspected of lymphomagenic potential. The aim of this study was to evaluate tumor-infiltrating lymphocytes for the evidence of clonal expansion in African KS. METHODS We used polymerase chain reaction (PCR)-based assays to determine the clonality of tumor-infiltrating lymphocytes in African KS lesions and compared the results to similar studies of patient-matched uninvolved skin and peripheral blood. RESULTS T cells were polyclonal in all samples tested. Peripheral blood B cells were also polyclonal; however, a minority of lesional and uninvolved skin samples exhibited evidence of restricted B-cell clonality. Correlation with immunohistological analysis revealed that this clonal B-cell restriction was secondary to the sparse nature of lesional B cells rather than their clonal overgrowth. CONCLUSIONS We conclude that, despite the putative lymphomagenic potential of HHV-8 and EBV and their co-existence in African KS lesions, tumor-infiltrating lymphocytes in these cases do not show evidence of clonal expansion that might be an early manifestation of lymphoma. Nevertheless, these studies are a case in point that sparse lymphoid subpopulations in lesional and uninvolved extranodal tissues can give rise to restricted clonal patterns that must be interpreted carefully to avoid the misdiagnosis of occult lymphoma.

Abstract
In 1993 we reported the efficacy and toxicity profile of an oral combination regimen administered to 18 patients with AIDS-related lymphoma (NHL-1 study). We observed a 61% response rate; 39% one-year survival rate; nearly two-thirds of patients developed > or = grade 3 leukopenia; and 28% of cycles were associated with febrile neutropenia. These results prompted us to shorten the duration of therapy and to add G-CSF to ameliorate the myelosuppression. Twenty patients with biopsy-proven AIDS-related lymphoma were treated with three 6-week cycles of oral chemotherapy consisting of lomustine (CCNU) 100 mg/m2 on day 1, cycles no. 1 and 3; etoposide 200 mg/m2 days 1-3; cyclophosphamide and procarbazine both 100 mg/m2 days 22-31; and G-CSF 5 microg/kg subcutaneously days 5-21 and days 33-42 (NHL-2 study). The following analyses were undertaken: (1) evaluation of toxicity and efficacy parameters for patients in the current (NHL-2) study; (2) analysis of the clinical role of G-CSF by (historical) comparison with the NHL-1 study of the same regimen without G-CSF; (3) quality-of-life assessments using the Functional Living Index-Cancer (FLIC) and Brief Symptom Inventory (BSI) instruments for all 38 patients (NHL-1+2); and (4) long-term follow-up for all 38 patients. In the current study the overall objective response using ECOG criteria was 70% (95% CI, 50-90%) with 6 CRs (30%) and 8 PRs (40%). The median survival duration was 7.3 months (range: 0.5-51+ months). One patient developed CNS relapse. There were no significant differences with respect to demographics or prognostic factors between the patient populations of the NHL-1 study and the current study (P > 0.2 for each factor). Myelosuppression was the major toxicity in both studies. In the current study versus the NHL-1 study, although the lower incidences of grade 3/4 myelosuppression (51% vs. 64%) and febrile neutropenia (17% vs. 28%) on a per cycle basis were not statistically significant, fewer patients (40% vs. 60%) were affected. However, the severity of myelotoxicity was lessened with the addition of G-CSF, measured in terms of the discontinuation of therapy, myelotoxic deaths, and freedom from grade 3/4 myelotoxicity ( P < 0.02). The number of hospitalizations for febrile neutropenia (7 in the NHL-2 study vs. 13 in the NHL-1 study) was also significantly different (P < 0.05). Quality-of-life analysis confirmed no significant functional or psychological deterioration during therapy except for patients experiencing febrile neutropenia, whose functional capacity deteriorated (P < 0.04). The 1-year, 18-month, and 2-year survival rates for the combined studies (38 patients) were 32%, 21%, and 13%, respectively. At time of death 49% of patients were free from progression of their lymphoma. Administration of the oral regimen has resulted in 13% of patients surviving two years, and half of patients surviving free from progression of their lymphoma. This regimen is efficacious and considerate of patient quality-of-life issues. The addition of G-CSF to the regimen decreases the frequency of hospitalization for febrile neutropenia.

Abstract
An oral combination chemotherapy regimen initially developed for AIDS-related non-Hodgkin's lymphoma includes lomustine (CCNU), etoposide, cyclophosphamide, and procarbazine. This regimen takes advantage of oral administration, the in vitro synergy of these drugs and their first-line efficacy in lymphoma, and the ability of lomustine and procarbazine to cross the blood-brain barrier. This regimen was used to treat 38 patients with AIDS-related non-Hodgkin's lymphoma. The overall objective response rate was 66% (34% complete response rate) with a 5% CNS relapse rate, and a median survival duration of 7.0 months. One-third of the patients survived for 1 year, 11% for 2 years, and half of the patients survived free from progression of their lymphoma. On the basis of these results, this oral regimen was modified and administered to 5 patients with AIDS-related primary CNS lymphoma as part of a sequential combined-modality chemotherapy and radiation regimen. Rapid progression of CNS disease was observed in this group of patients, with a median survival duration of 1.0 month. The identical regimen was administered to 7 patients with AIDS-related Hodgkin's disease: we observed a 71% partial remission rate and a median survival duration of 7.0 months. Myelosuppression remains the most significant clinical toxicity. Our results with this oral regimen appear comparable to those of standard intravenous combination chemotherapy regimens in patients with AIDS-related non-Hodgkin's lymphoma.

Abstract
PURPOSE To determine the feasibility of adding paclitaxel to standard cisplatin/etoposide (EP) and thoracic radiotherapy. PATIENTS AND METHODS Thirty-one patients were enrolled onto this study. During the phase I section of this study, the dose of paclitaxel was escalated in groups of three or more patients. Cycles were repeated every 21 days. For cycles 1 and 2, paclitaxel was administered according to the dose-escalation schema at doses of 100, 135, or 170 mg/m(2) intravenously over 3 hours on day 1. Once the maximum-tolerated dose (MTD) of paclitaxel (for cycles 1 and 2, concurrent with radiation) was determined, that dose was used in all subsequent patients entered onto the phase II section of this study. For cycles 3 and 4, the paclitaxel dose was fixed at 170 mg/m(2) in all patients. On day 2, cisplatin 60 mg/m(2) was administered for all cycles. On days 1, 2, and 3, etoposide 60 mg/m(2)/d (cycles 1 and 2) or 80 mg/m(2)/d (cycles 3 and 4) was administered. Chest radiation was given at 9 Gy/wk in five fractions for 5 weeks beginning on day 1 of cycle 1. Granulocyte colony-stimulating factors were used during cycles 3 and 4 only. RESULTS Twenty-eight patients were assessable. The MTD of paclitaxel was 135 mg/m(2), with the dose-limiting toxicity being grade 4 neutropenia. Cycles 1 and 2 were associated with grade 4 neutropenia in 32% of courses, with fever occurring in 7% of courses and grade 2/3 esophagitis in 13%. Cycles 3 and 4 were complicated by grade 4 neutropenia in 20% of courses, with fever occurring in 6% of courses and grade 2/3 esophagitis in 16%. The overall response rate was 96% (complete responses, 39%; partial responses, 57%). After a median follow-up period of 23 months (range, 9 to 40 months), the median survival time was 22.3 months (95% confidence interval, 15.1 to 34.3 months) CONCLUSION The MTD of paclitaxel with radiation and EP treatment is 135 mg/m(2) given over 3 hours. In this schedule of administration, a high response rate and acceptable toxicity can be anticipated.

Abstract
TLC D-99 is a unique liposomal formulation of doxorubicin that consists of phosphatidyl choline/cholesterol. The objectives of the study were to evaluate safety and efficacy of two doses of TLC D-99 in the treatment of patients with AIDS-related Kaposi's Sarcoma (KS). Forty HIV-infected persons with biopsy-proven KS were randomized to receive TLC D-99 at doses of either 10 (low) or 20 (high) mg/m2 every 2 weeks. Patients assigned to the low-dose arm could be escalated to the high-dose arm if their KS progressed after 3 cycles of therapy. Median age was 35 years (range, 26-47) and median CD4 count was 13 (range, 0-440). Nineteen patients were assigned to receive the low dose, and 21 patients were assigned to the high dose. Partial response occurred in 15% (6 of 40) of the patients or in 5% (1 of 19) and 24% (5 of 21) in the low- and high-dose arms, respectively; stable disease was observed in 65% (26 of 40) or in 68% (13 of 19) and 62% (13 of 21) in the low and high doses, respectively. Neutropenia was the major toxicity and was observed in 68 and 81% of patients with the low- and high-dose arms, respectively; grade 4 neutropenia was observed in 16 and 14%, respectively. Mild alopecia was noted in only 8%. Therefore, TLC D-99 is active against AIDS-related KS, and the response is dose-dependent.

Abstract
Increased levels of serum interleukin 6 (IL-6) are found in patients with lung cancer, and it has been shown that this is part of a systemic inflammatory response syndrome. This study was designed to measure IL-6 levels in bronchoalveolar lavage (BAL) fluid of patients with lung cancer and to describe the relationship of BAL fluid IL-6 to the known systemic increase in IL-6. Increased levels of BAL fluid IL-6 can be found in patients with lung cancer as compared with patients with chronic obstructive pulmonary disease who have acute infection (P = .007). In patients with cancer, no correlation between BAL fluid IL-6 and serum IL-6 was found (P = .8). BAL fluid IL-6 did not correlate with the number of lymphocytes or macrophages found in this fluid. BAL fluid IL-6 does not correlate with tumor size. Although serum IL-6 was higher in patients with extensive stage small cell lung cancer as compared with levels in patients with limited stage disease (P = .06), their corresponding BAL fluid levels were not different (P = .9). Serum IL-6 correlated with other acute phase reactants. This study thus demonstrates the feasibility of utilizing BAL fluid analysis for local cytokine/tumor marker production in lung carcinoma. It also shows that a local increase in IL-6 in the BAL fluid is independent of the systemic inflammatory response syndrome, whereas the serum increase in IL-6 is part of this syndrome.
