An early phase II study of a new camptothecin analog and an inhibitor of topoisomerase I, CPT-11, was conducted in 62 patients with refractory leukemia and lymphoma by four different treatment schedules in a multiinstitutional cooperative study. CPT-11 therapy resulted in four complete remissions (CRs) and three partial remissions (PRs) in 29 assessable non-Hodgkin's lymphoma (NHL) patients, one PR in three Hodgkin's disease (HD), one CR and one PR in 11 acute lymphoblastic leukemia (ALL), and one PR in 15 acute myelogenous leukemia (AML) patients. Single infusion of 200 mg/m2 every 3 to 4 weeks produced no response in both leukemia and lymphoma patients. Sixty-minute infusions of 40 mg/m2/d for 5 days every 3 to 4 weeks or for 3 days weekly produced four CRs (17%) and four PRs (17%) in 24 patients with malignant lymphoma. Sixty-minute infusions of 20 mg/m2 twice a day for 7 days every 3 to 4 weeks resulted in one CR and two PRs in 12 patients with acute leukemia. No response was seen in an acute leukemia patient by another treatment schedule. CPT-11 was effective in two (15%) of 13 primarily refractory leukemia and lymphoma cases, in two of four relapsed cases, and in seven (17%) of 41 relapsed and refractory cases. Major side effects were leukopenia (91%) and gastrointestinal (GI) (76%). CPT-11 was shown to be effective against refractory leukemia and lymphoma, and thus deserves further clinical study; the novel antitumor activity mode of this drug predicts no cross-resistance to presently available antitumor drugs.

Testicular function was evaluated in 60 long-term survivors of childhood acute lymphoblastic leukemia (ALL). All the patients were treated on two consecutive Children Cancer Study Group protocols and received identical chemotherapy and either 18 or 24 Gy radiation therapy (RT) to one of the following fields: craniospinal plus 12 Gy abdominal RT including the gonads (group 1); craniospinal (group 2); or cranial (group 3). The median age at the time of their last evaluation was 14.5 years (range, 10.5 to 25.7), which took place a median of 5.0 years (range, 1 to 10.3) after discontinuing therapy. The incidence of primary germ cell dysfunction as judged by raised levels of follicle-stimulating hormone (FSH) and/or reduced testicular volume was significantly associated with field of RT; 55% of group 1, 17% of group 2, and 0% of group 3 were abnormal (P = .002). Leydig cell function, as assessed by plasma concentrations of luteinizing hormone (LH) and testosterone, and pubertal development, was unaffected in the majority of subjects regardless of RT field. These data indicate that in boys undergoing therapy for ALL, germ cell dysfunction is common following testicular irradiation and can occur following exposure to scattered irradiation from craniospinal RT. In contrast, Leydig cell function appears resistant to direct irradiation with doses as high as 12 Gy.
Current urinary mass screening for catecholamine metabolites at 6 months of age may be detecting only a small portion of high-risk neuroblastomas: a chromosome and N-myc amplification study.

Published: February 2017

We studied 96 infants and children with untreated neuroblastomas. Chromosomes of tumor cells were analyzed in 68, and N-myc copy numbers were determined in 67 patients. Patients found by a mass screening program for 6-month-old infants (group A1, 39 patients) or those less than 12 months of age found clinically (group A2, 13 patients) were rarely in the disseminated stage (A1, three of 39; A2 one of 13); their tumors usually had near-triploid (3n) or hypertetraploid (greater than 4n) karyotypes (A1, 28 of 37; A2, nine of 11), and never had N-myc amplification (A1, zero of 34; A2, zero of 11). In contrast, children 12 months or over (group B, 27 patients) were usually in the disseminated stage (19 of 27) (P less than .0001); their tumors usually had near-diploid (2n) or near-tetraploid (4n) karyotypes (16 of 20) (P = .0027), and often had N-myc amplification (nine of 22) (P less than .0001). Of the 40 clinically found patients (A2 and B), six had undergone the screening with a negative result at the age of 6 months. Two of the six patients had N-myc amplification in the tumors. Most tumors found by the screening showed known characteristics predicting a good prognosis, and the majority of tumors showing characteristics predicting a poor prognosis were found in patients aged between 12 and 36 months. Our chromosome and N-myc amplification studies suggest that a low-risk tumor does not usually evolve to a high-risk tumor. Thus, the current mass screening program may be detecting only a small portion of highly malignant neuroblastomas at the earliest stage. Infants should be screened twice, at 6 months as well as at 12 months of age, for the early detection of high-risk neuroblastomas.

Staging laparotomy was performed as part of the routine recommended diagnostic evaluation following clinical staging (CS) in 692 patients presenting with supradiaphragmatic Hodgkin's disease (HD). Various clinical factors were analyzed by multivariate analysis for prediction of abdominal involvement. Factors that were statistically significant for predicting disease below the diaphragm included CS III-IV disease (P less than .001), B symptoms (P less than .001), mixed cellularity (MC) or lymphocytic depletion (LD) histology (P = .017), number of supradiaphragmatic sites greater than or equal to 2 (P = .001), male sex (P = 0.034) and age greater than or equal to 40 years (P = .004). Separate analyses were performed for various subgroups of CS IA-IIA, CS IB-IIB, CS IIIA-IVA, and CS IIIB-IVB patients. Upstaging was seen in 0% to 55% of CS I-II patients based on subgroup. Male sex, B symptoms, and number of sites above the diaphragm greater than or equal to 2 all independently predicted for positive surgical staging in CS I-II patients. Sixty-four percent of CS I-II patients who were upstaged had extensive abdominal disease by positive lower abdominal nodes or multiple splenic nodules (greater than or equal to 5). Downstaging (to pathological stage [PS] I-II) was seen in 9% to 68% of patients with CS III-IV disease based on subgrouping. Age greater than or equal to 40, MC or LD histology, and B symptoms all independently predicted for positive surgical staging in CS III-IV patients. Downstaging was more frequently seen in CS IIIA-IVA patients (55%) than in patients who were CS III-IVB (22%). Four subgroups of patients who had a low probability (less than 10%) of stage or treatment change following laparotomy were identified. These included CS IA female patients, CS IA male patients with lymphocyte predominance histology or high neck presentations, and patients with CS IIIB-IVB disease and account for 21% of the study population. Staging laparotomy altered the stage and treatment of a significant number of the remaining 79% patients and should continue to be recommended for this group of patients.

We conducted a randomized multicenter trial comparing low-dose cytarabine (LD ARA-C) (20 mg/m2 for 21 days) with an intensive chemotherapy (rubidazone [a daunorubicin-derived agent], 100 mg/m2 for 4 days, ARA-C 200 mg/m2 for 7 days) in 87 patients over 65 years of age with de novo acute nonlymphocytic leukemia (ANLL). Forty-one patients received LD ARA-C and 46 received intensive chemotherapy. The number of complete remissions (CRs) but also of early deaths was higher in the intensive chemotherapy group, while partial remissions (PRs) and failures were more frequent in the LD ARA-C group (P less than .001). Infectious complications during induction treatment were more numerous and more severe in the intensive chemotherapy group (P less than .01). Patients treated with LD ARA-C required fewer RBC transfusions (P less than .02), fewer platelet transfusions (P less than .01), and had a shorter hospital stay for induction treatment (P less than .01). Overall survival and CR duration were not significantly different in either group. In the LD ARA-C group, the survival of patients with PR and those of patients in CRs was identical. We conclude that in a selected group of elderly patients with de novo ANLL a higher number of CRs may be obtained with intensive chemotherapy, but that with LD ARA-C, the number of early deaths is lower, and long-lasting PRs are obtained, resulting in a similar overall survival.

Published: February 2017

Medulloblastoma, pineoblastoma, and cerebral neuroblastoma are malignant embryonal tumors of the CNS that may demonstrate similar histologic features, a propensity for neuraxis dissemination and sensitivity to radiation therapy and, in certain cases, chemotherapy. To evaluate the activity of preirradiation chemotherapy in such tumors, 11 newly diagnosed children with measurable residual disease and characteristics indicative of poor prognosis were treated postoperatively with cisplatin (CDDP) and etoposide (VP-16). Responses graded on the basis of radiographic findings in areas of either macroscopic residual tumor or metastatic disease included two complete responses (CRs), eight partial responses (PRs), and one stable disease (SD). Acute and subacute toxicity consisted of high-frequency hearing loss in four patients, reversible signs and symptoms of increased intracranial pressure in two patients, and transient neutropenia. Seven of eight patients with high-risk medulloblastoma and two of two with pineoblastoma remain free of tumor progression following neuraxis irradiation at 8 to 48 months postdiagnosis (median, 18 months). CDDP and VP-16 is a highly active drug combination when given before irradiation in children with high-risk medulloblastoma and other malignant embryonal tumors of the CNS, producing objective responses in at least one site of measurable disease in 10 of 11 newly diagnosed patients, including all of five with gross neuraxis dissemination.
Adaptive behavioral responses to potential infertility among survivors of testis cancer.
Authors: Rieker P P , Fitzgerald E M , Kalish L A
Published: February 2017

In a retrospective study of 153 testis cancer survivors, we examined the sociodemographic and clinical determinants of attitudes and behaviors toward illness-induced infertility. Five fertility adjustment responses were identified: sperm-banking awareness (SBA); adoption awareness (AA); fertility testing (FT); trying to father children (TFC); and fertility distress (FD). Although responses to infertility are multidetermined, these data demonstrate there is a distinct sociodemographic and clinical profile for the subgroups of men who engage in different fertility-related behaviors. Multivariate analysis results show that men most likely to be concerned with banking sperm are those who at diagnosis are younger (less than 35 years), childless, college educated, and whose relationships have become strained. Men who sought fertility tests were childless, college graduates, and able to ejaculate. The only factor predicting adoption was childlessness. Those married men attempting to father children were also less than 35 years of age at diagnosis and without ejaculatory dysfunction. The men at greatest risk for continued distress about infertility were those who remained childless and had posttreatment ejaculatory dysfunction. Residual infertility distress also was significantly associated with treatments that included extensive retroperitoneal lymph node dissection (RPLND) surgery, indicating that the latter is a "risk factor" in survivors' long-term distress. These data, while not definitive, show that the prerogative to have children is very important to men and that losing it sets into motion a range of both adverse emotions and adaptive responses. Adjustment to infertility is a complex process that begins at diagnosis and extends long after treatment is completed.
The effect of compliance with treatment on survival among patients with hematologic malignancies.

Published: February 2017

Ninety-four newly diagnosed patients with hematologic malignancies were monitored for compliance with oral medication and scheduled clinic appointments over a 6-month treatment period. They were assigned at entry either to a control condition or an intervention condition designed to improve compliance. Compliance with medication was assessed objectively with serial serum drug and metabolite levels, as well as with self-report indices obtained on a monthly basis. Medical records were abstracted to obtain data on the number of appointments kept, treatment given, disease characteristics, and survival. On univariate analyses using the log-rank test, five variables were found to be significantly related to survival. These included compliance with allopurinol (probably acting as a surrogate for self-medication with other chemotherapeutic agents) (P = .007), control versus educational program cohort (P less than .001), disease severity (P = .009), Karnofsky at diagnosis (P = .011), sex (P = .084), and clinic appointments kept (P = .043). In hierarchical proportional hazards models, the following variables were associated with decreased risk of death: disease severity (P less than .025), keeping over 60% of appointments (P less than .05), allopurinol/oxipurinol compliance (P less than .01), and educational program cohort (P less than .05). After controlling for all other variables, three variables were associated with increased survival: high disease severity (relative risk [RR] = 2.48), high compliance with allopurinol (RR = .45), and educational program cohort (RR = .39). We conclude that compliance with oral medication has a significant effect on patient survival. In addition, the use of special educational and supportive programs designed to improve patient compliance are associated with significant prolongation of patient survival due to, as well as independent of their effects on compliance.

Published: February 2017

Polymorphic B-cell lymphoma seen in four patients with congenital immunodeficiencies and in two patients with leukemia receiving chemotherapy was associated with the Epstein-Barr virus (EBV). The tumors had characteristic histologic features: they were polymorphic consisting of a mixture of lymphoblasts and differentiated cells including plasma cells, and areas of hemorrhagic necrosis were prominent. The tumors were either polyclonal, monoclonal, or multiclonal. Patients with congenital immunodeficiencies who developed these tumors died despite radiotherapy, corticosteroids plus acyclovir, or a combination of intravenous (IV) immunoglobulins and alpha 2 interferon. Patients with leukemia recovered when immunosuppressive drugs were discontinued and leukemia has not recurred over a period of 2 and 4 years, respectively, in the two patients.
Epirubicin in extensive small-cell lung cancer: a phase II study in previously untreated patients: a National Cancer Institute of Canada Clinical Trials Group Study.

Published: February 2017

The Clinical Trials Group of the National Cancer Institute of Canada (NCIC) studied single-agent epirubicin in 40 previously untreated patients with extensive small-cell lung cancer (SCLC). The starting dose of epirubicin was 100 (eight patients) or 120 (32 patients) mg/m2 administered intravenously every 3 weeks. Twenty patients (50%) achieved an objective response (95% confidence limits, 33% to 66%) and three of the 20 had complete responses (CRs). The median survival of all 40 patients was 8.3 months (35.4 weeks). Myelosuppression, mild or moderate nausea and vomiting, and hair loss were commonly seen. There was one chemotherapy-related death. This drug is active and well tolerated in SCLC and the use of it as first-line therapy did not appear to compromise survival in this group of patients.
Lack of apparent difference in outcome between clinically staged IIIA and IIIB non-small-cell lung cancer treated with radiation therapy.
Authors: Curran W J , Stafford P M
Published: February 2017

The current American Joint Committee on Cancer (AJCC) staging system for bronchogenic carcinoma, which divides stage III M0 cases into stages IIIA and IIIB, is based on the observation that selected patients with IIIA disease (T3 or N2) can undergo complete surgical resection, in distinction to IIIB patients (T4 or N3). To understand the value of this system when applied to clinically staged (CS) patients treated with a standard nonoperative approach, the records of patients with squamous cell, large-cell, and adenocarcinoma of the lung treated with radiation therapy (RT) at the Fox Chase Cancer Center from 1978 to 1987 were reviewed. Three hundred sixteen patients were identified as having CS III M0 disease treated with single daily fraction RT without chemotherapy or sensitizers. Of these, the distinction between IIIA (166) and IIIB (140) could be made for 306 patients. The median survival time (MST) for all CS III patients was 9.6 months, and the 2-year survival was 17%. No difference was observed in MST between CS IIIA and IIIB patients (9.4 v 9.8 months, P = .78), in 2-year survival (17% v 18%), or in rate of first failure within the RT field (43% v 44%). MSTs for the 157 CS IIIA and IIIB patients with less than 5% weight loss and Zubrod performance status (PS) 0 to 1 were 13.0 and 15.8 months (P = .29), respectively. This lack of difference in outcome for CS IIIA and IIIB patients receiving RT has important implications in the design and stratification of future nonoperative trials for stage III lung cancer.

Prestudy patient characteristics and specific therapy of all eligible patients with rhabdomyosarcoma entered into Intergroup Rhabdomyosarcoma (RMS) Studies I (IRS-I) (1972 to 1978, n = 686) or II (IRS-II) (1978 to 1984, n = 1,002) were examined for their relationship to survival within each of the four clinical groups using univariate and multivariate analyses. The estimated survival at 5 years from the start of treatment was 56% in IRS-I and 62% in IRS-II (P = .006). The largest survival difference between studies was in patients with group III tumors (52% v 65%). The clinical group was the most important patient characteristic related to survival in both studies. Survival progressively decreased for patients from clinical group I (localized disease, completely resected) to group IV (metastatic disease at the onset). In clinical group I, the only patient characteristic consistently related to survival was histology. Patients with alveolar tumors had the poorest survival, while those with botryoid/embryonal lesions had the best survival. In clinical group II, no characteristic was consistently related to survival. In clinical group III, an orbital primary site was associated with a favorable survival. In clinical group IV, patients with genitourinary tumors had a significant survival advantage. Use of disease-free survival as an end point gave very similar results. This information, from the largest available data base on prognostic indicators in childhood RMS in the context of aggressive multimodal therapies, is being used to plan therapy in the forthcoming study (IRS-IV).
Adjuvant systemic therapy for breast cancer in the elderly: competing causes of mortality. International Breast Cancer Study Group.

Published: February 2017

Between 1978 and 1981 we conducted a trial in which adjuvant endocrine therapy consisting of tamoxifen (T = 20 mg/d) and low-dose prednisone (p = 7.5 mg/d) for the duration of one year (p + T), was compared with no adjuvant therapy (observation) in 320 women with operable breast cancer aged 66 to 80 years (median age, 70 years). All patients had axillary lymph node metastases after at least a total mastectomy and axillary clearance. At 96 months median follow-up, 9.1% of the patients died without apparent relapse from cancer. An additional 1.9% had a second malignant neoplastic disease (not breast cancer). The 8-year disease-free survival (DFS) percentages (+/- SE) for the p + T and the observation groups were 36% (+/- 4%), and 22% (+/- 3%), (P = .004). The 8-year overall survival percentages were 49% (+/- 4%) and 42% (+/- 4%), respectively (P = .43). We conclude that despite a large proportion of deaths without relapse of breast cancer, a significant advantage for the p + T group in terms of DFS was demonstrated. We hypothesize that an endocrine therapy of longer duration might have an overall survival benefit in a population of elderly patients.

Published: February 2017

The purpose of this study was to determine which factors were associated with an increased risk of thrombo-hemorrhagic complications in a historical cohort of 100 consecutive and unselected patients with essential thrombocythemia (ET) in whom busulfan treatment was given when platelets were more than 1,000 x 10(9)/L and/or a major thrombotic or hemorrhagic event occurred. The incidence of major hemorrhagic complications was very low (0.33%/person-time at risk [pt-yr]) in comparison with that of thrombotic episodes (6.6%/pt-yr). In an adequate and appropriate control historical group of 200 patients, no severe hemorrhages were recorded and the incidence of thrombotic events was 1.2% pt-yr. Thus, the analysis of risk factors was restricted to this latter group of events. Age, a previous thrombotic event, and long duration of thrombocytosis were identified as major risk factors for thrombosis, while smoking, diabetes mellitus, hyperlipidemia, and hypertension did not influence the rate of thrombotic episodes.

Published: February 2017

Information on the past medical history of the mothers of a population-based series of 177 children with soft tissue sarcoma was obtained by interview and from medical records. Eight mothers developed breast cancer, six premenopausally, compared with 3.26 expected (P = .04), but no excess of other types of cancers was detected. High breast cancer risk was associated with the following factors in the index child: age at diagnosis less than 24 months (relative risk [RR], 7.84), embryonal rhabdomyosarcoma (RR, 3.74), and male sex (RR, 3.02). Characteristics in the mother associated with high breast cancer risk were the following: late age at first birth (RR, 5.13), late age at birth of index child (RR, 5.69), and high birth-rank order of index child (RR, 4.08). The results suggest there may be a subset of childhood soft tissue sarcoma with a predominantly genetic etiology. The association between premenopausal breast cancer in the mother, late age at birth of index child, and early onset of soft tissue sarcoma in the index child suggests that these three events are not independent and that interactions between genetic and other factors may be important. The identification of a group of women at high risk for breast cancer affords an opportunity for screening and early detection. The study of cancer family syndromes may provide insights into underlying mechanisms in cancer genetics.
Small noncleaved cell lymphoma in adults: superior results for stages I-III disease.

Published: February 2017

Small noncleaved cell lymphoma (SNCCL), a rare lymphoma in adults, is associated with not only a rapid complete response (CR) to chemotherapy but also with the potential to rapidly relapse both systemically and in the CNS. We treated 44 assessable adults with two similar protocols, consisting of three sequential chemotherapy combinations and intrathecal prophylaxis with methotrexate and cytarabine. The overall CR rate was 80%; it was 100% in patients with Ann Arbor (AA) stages I-III disease and 57% in those with stage IV disease. The overall survival (OS) rate at 5 years was 52%. The overall 5-year freedom from tumor mortality (FTM) rate was 63%; it was 95% for patients with AA stages I-III disease, and 29% for those with stage IV disease. Stepwise multivariate analysis of factors associated with remission duration and survival indicated that advanced-disease stage and age of 40 years or over were predictors of poor prognosis. Twelve patients with positive human immunodeficiency virus (HIV) serology were also included in this series. They had an 83% CR rate and an 83% 5-year FTM, but only a 36% 5-year OS; most deaths were secondary to opportunistic infection. Histologic subtype (Burkitt's lymphoma [BL] or non-Burkitt's lymphoma [NBL]) did not correlate with patient age, site of tumor presentation, response to therapy, or survival. Both protocols achieved comparable results. The approach used in these protocols is highly effective for patients with early staged disease, regardless of their HIV status; however, better therapy is necessary for those with SNCCL presenting in an advanced stage.

Forty-six patients with non-Hodgkin's lymphoma (NHL) were treated with autologous bone marrow transplantation (ABMT) in two different institutions. All patients were pretreated with conventional chemotherapy. Three different conditioning regimens were used, and 20 patients underwent bone marrow purging. Twelve patients were treated in first complete remission (CR); eight are in unmaintained CR 8 to 104 months after ABMT. Five patients were grafted in first partial remission (PR) after conventional therapy; all achieved CR, and all remain in prolonged CR (first CR for four patients, second CR for one patient). Of 21 patients with chemosensitive relapses, 13 patients are in prolonged unmaintained CR 8 to 94 months after ABMT. Eight patients with resistant disease remained uncured by ABMT; all eight died, six from progressive illness and two from toxicity. The current 3-year disease-free probability is 60% for all patients, 0% for refractory disease; 82% for first PR or CR, and 60% for sensitive relapses (SRs). These results confirm the efficacy of ABMT in the treatment of chemosensitive NHL with bad prognosis.

Fifteen patients with hairy cell leukemia (HCL) were treated with deoxycoformycin (pentostatin; dCF) (4 mg/m2 intravenous [IV] every week x 3) and recombinant interferon-alpha 2a (rIFN-alpha 2a) (3 x 10(6) units subcutaneously [SC] daily x 4 weeks) in alternating months for a total of 14 months. Eleven patients had undergone splenectomy; four had received prior systemic therapy with chlorambucil and/or steroids. All 15 are evaluable for toxicity and peripheral blood response, while 14 are assessable for bone marrow response. Toxicity was tolerable with grade 3 or 4 nausea and vomiting in three patients, neutropenic fevers in five, transient but significant depression in eight, and localized cutaneous herpes zoster in four. Circulating hairy cells were undetectable by the end of the first month in 10 of 13 patients, and by the end of the second month in the other three. Fourteen patients had bilateral bone marrow biopsies performed at baseline after 6 months of treatment, at the end of treatment (14 months), and at 6-month intervals during follow-up. Before treatment, all patients had hypercellular marrows with hairy cels replacing normal marrow elements; all showed at least a 95% clearing of their hairy cell infiltrate by 6 months of therapy. However, small collections of residual hairy cells could be detected intermittently on at least one side of bilateral samples in all patients. All patients have completed treatment with a median duration of follow-up off therapy of 27 months (range, 15 to 31 months). To date, all peripheral counts and serum soluble interleukin-2 receptor (sIL2R) levels remain stable, and no patient has had progression of the hairy cell infiltrate in the bone marrow. Although no patient achieved a pathologic complete response, alternating monthly cycles of dCF and rIFN-alpha 2a produced durable partial remissions (PRs) in all patients. Continued follow-up is required to determine the length of such remissions.

Published: February 2017

The immune function of patients with hairy cell leukemia (HCL) and solid tumors was evaluated before and after treatment with the investigational drug 2'-deoxycoformycin (pentostatin; dCF). Thirteen HCL patients received doses of dCF of 2 to 4 mg/m2 intravenously at 2- to 6-week intervals for up to 15 courses. After completion of treatment, 12 of 13 patients had resolution of severe monocytopenia and five of nine had normal monocyte antibody dependent cellular cytotoxicity. There was statistically significant depression of total lymphocytes, T cells, and B cells. Evaluation of T subsets showed a decrease in CD4+ cells. Immunoglobulin G (IgG) in sera were decreased from baseline, while IgM and IgA were unaffected. There was no significant effect on skin-test reactivity or large granular lymphocyte numbers. Lymphoblastic transformation was variably affected. Natural-killer (NK) cell function was improved or unchanged after dCF treatment. Reevaluation of seven patients at 21 to 119 weeks after receiving dCF demonstrated that recovery to normal T- and B-cell numbers and subsets does occur. Five solid tumor patients were given dCF at 4 mg/m2 intravenously at 1- to 2-week intervals for up to five courses. There was significant reduction in T cells, B cells, CD4+, and CD8+ cells with no statistically significant effect on the other immune parameters. We conclude that low doses of dCF can cause persistent immunosuppression though recovery may occur after the drug is stopped. In patients followed after completion of dCF, there was no associated increase in second malignancies or unusual infections.

Patients with advanced nonsmall-cell lung cancer (NSCLC), good performance status, and no prior chemotherapy were randomized to receive one of three regimens: intravenous vindesine (V) 3 mg/m2 every 2 weeks; V 3 mg/m2 weekly for 5 weeks, followed by a dose every 2 weeks plus mitomycin (VM) 20 mg/m2 day 1 and then 15 mg/m2 every 6 weeks; or V at the more intensive dose rate plus cisplatin (VC) 120 mg/m2 with forced diuresis on days 1 and 29 and then every 6 weeks. A total of 435 patients were enrolled in the trial, with 410 (94%) assessable for prognostic characteristics and survival. Among the 375 patients assessable for response, only 58 (15%) achieved objective response. Single-agent V every 2 weeks was inactive (response rate less than 1%), effectively acting as a no-treatment arm. Among assessable patients receiving VM, 33 (27%) responded; among patients receiving VC, 24 (19%) responded. There was no statistically significant survival difference among the treatment arms, with median survival among those treated with V 14.8 weeks, VM 20.4 weeks, and VC 24.7 weeks; VC achieved borderline significance (P = .06) compared with V. In a prognostic factor analysis, treatment was not a significant factor (P = .447) for survival. Thus, in this large multicenter trial, neither a high-dose cisplatin combination nor a noncisplatin regimen (VM) with a comparable response rate had a significant survival advantage over minimal chemotherapy. New approaches are needed in advanced NSCLC.

We have treated 14 cancer patients with liposome-encapsulated doxorubicin (LED) at doses of 30, 45, 60, and 90 mg/m2. Nausea and vomiting, phlebitis, and stomatitis were minimal or absent at each dose, but dose-limiting granulocytopenia occurred at 90 mg/m2. Thrombocytopenia and/or anemia also occurred in all patients treated at 60 or 90 mg/m2. Complete alopecia was seen in one of three cases at 60 mg/m2 and all cases at 90 mg/m2. No hepatic, renal, or other major organ toxicities were encountered. Clinical cardiac toxicity did not occur in any patient, but the cumulative doxorubicin doses in 13 cases were less than 400 mg/m2. The plasma elimination of LED out to 24 hours was analyzed in terms of a two-compartment model. Depending upon the dose and the infusion time, maximum plasma concentrations ranged from 2.6 mumol/L to 36.89 mumol/L and the area under the plasma concentration x time curve (AUC) values ranged from 1.86 mumol/L x h/L to 49.57 mumol x h/L. These values are significantly higher than those expected for free doxorubicin. Urinary excretion of LED was approximately 10% after 24 hours. Doxorubicinol and doxorubicinone appeared at low levels in plasma 12 to 24 hours after injection. LED pharmacokinetics differ from those of free drug by the higher plasma levels and AUC of doxorubicin achieved, and by the low conversion of LED to metabolites. Overall, LED was well tolerated and produced only moderate nausea and vomiting and little stomatitis at myelosuppressive doses. The study also suggested that LED produces less venous sclerosis than free doxorubicin, but this requires further clinical verification.

Fifty-one patients with unresectable hepatocellular carcinoma (HCC) were treated with Gelfoam (absorbable gelatin sterile powder; The Upjohn Co, Kalamazoo, MI) chemoembolization. A mixture of Gelfoam powder, contrast media, and three drugs (doxorubicin, mitomycin, and cisplatin) was injected under fluoroscopic guidance via a percutaneous catheter into the hepatic artery until stagnation of blood flow was achieved. Of the 51 patients, 50 are assessable for response, and all are assessable for toxicity and complications. The median percent of liver replacement was 50% (range, 15% to 95%). By conventional response criteria, there were 12 partial responses (PRs) (24%), 13 minor responses (MRs) (26%), 12 stabilization of disease (SD) (24%), and 13 (26%) progressive disease (PD). Tumor liquefaction was noted on computed tomographic (CT) scan in 35 of 50 patients (70%). Of the 34 patients with elevated alpha-fetoprotein (AFP), 23 (68%) had a greater than 50% reduction following treatment. Responding patients were re-treated at the time of tumor progression if they still met the entry criteria. The median survival of assessable patients from the time of treatment was 207 days and from the diagnosis of the primary was 302 days. Fourteen patients remain alive at 3 months to 3 years following treatment. The vast majority of patients had transient pain, fever, nausea, and elevation in liver enzymes. Ascites developed in 14 patients. There were two treatment-related deaths: one from tumor hemorrhage and one from liver failure. Chemoembolization appears to have significant activity in patients with hepatocellular carcinoma and is relatively well tolerated.

One hundred five untreated adult patients with acute lymphocytic leukemia (ALL) were entered on the vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and Decadron (dexamethasone; Merck Sharp and Dohme, West Point, PA) (VAD) regimen. Induction therapy with VAD and VAD plus cyclophosphamide (CVAD) was followed by a 2-year rotating maintenance program with multiple antileukemic combinations, and included early intensifications with Adriamycin and high-dose cytarabine (ara-C) and a late intensification with cyclophosphamide, carmustine (BCNU), and etoposide (VP-16) (CBV) followed by autologous bone marrow transplantation (BMT). Duration of therapy was 24 to 30 months. Eight-eight patients (84%) achieved complete remission (CR) with VAD-CVAD, and 94 (90%) ultimately had CR with continuation of the maintenance as planned. Induction mortality was 3%; only half of the patients required prolonged hospitalization of 1 week or longer, or intravenous antibiotics. Maintenance therapy was given to 79 patients, while nine with histocompatibility locus antigen (HLA)-matched related donors underwent allogeneic BMT. The median remission duration was 22 months, and the median survival was 19 months. Factors associated with significantly worse CR rates were older age, the presence of hypoalbuminemia or hyperbilirubinemia, L2 or L3 morphology, and myeloid markers on leukemic cells. Those associated with significantly worse remission durations were the presence of elevated leukocyte or absolute peripheral blast counts, Philadelphia chromosome (Ph)-positive or B-cell ALL, L2 morphology, and more than one course to achieve CR. Patients could be divided into standard-risk ALL (28% of patients) and high-risk ALL (72% of patients) with long-term remission rates of 70% versus less than 30%. The 26 patients who underwent CBV autologous BMT had similar long-term outcome compared with 21 patients who did not (older age, medical contraindications, or socioeconomic problems). The presence or absence of myeloid markers on leukemic cells did not affect long-term prognosis. We conclude that VAD therapy is a well-tolerated effective induction regimen. High-risk ALL patients require alternative maintenance investigational approaches.

The purpose of this study was to evaluate the influence of the number of mechlorethamine, vincristine, procarbazine, and prednisolone (MOPP) cycles and the extent of irradiation on the risk of secondary acute nonlymphocytic leukemia (SANLL) after a single combined treatment for Hodgkin's disease (HD). Between April 1972 and May 1980, 462 patients with HD clinical stage (CS) I, II, and III were prospectively treated with three or six cycles of MOPP and supra- and/or infradiaphragmatic irradiation (40 Gy). Four hundred forty-one patients achieved complete remission (CR). By January 1988, 237 patients had been followed-up in first CR for at least 10 years. Ten patients developed SANLL between the 34th and 123rd month of CR. The 15-year SANLL risk is 3.5% +/- 2.7%. Cox's stepwise regression analysis performed with all initial and treatment covariates (sex, age, histology, splenectomy, MOPP chemotherapy, and irradiation extent) showed that the only significant explanatory variable of SANLL risk was the irradiation extent (P less than .002). Using the log-rank test, SANLL risk ranged from 2.2% for supradiaphragmatic irradiation alone to 9.1% for subtotal (STNI) or total nodal irradiation (TNI) (P less than .001). These results strongly suggest that extended high-dose irradiation and MOPP chemotherapy should not be combined for the treatment of HD.

One hundred six eligible patients with advanced intermediate- or high-grade malignant lymphoma were treated with methotrexate with leucovorin rescue, bleomycin, doxorubicin, cyclophosphamide, vincristine, and dexamethasone (m-BACOD) in a Southwest Oncology Group phase II trial. Patients were stratified by estimated bone marrow reserve, and impaired marrow reserve patients received reduced doses of cyclophosphamide and doxorubicin. The complete remission rate for normal marrow reserve patients was 65%, while the complete remission rate for impaired marrow reserve patients was 29%. With a median follow-up period of 41 months, 64% of complete responders in the normal marrow group are disease-free 3 years after their response. Three-year survival is 61% in the normal marrow reserve group and is 29% in the impaired marrow reserve group. Eighty-seven percent of treatment courses were given in accordance with protocol dosing and schedule. For doxorubicin, relative dose intensities were 0.75 and 0.61 (normal and impaired marrow reserve arms, respectively), for cyclophosphamide, 0.76 and 0.61, and for methotrexate, 0.55 and 0.45. Serum lactic dehydrogenase (LDH) level was the only pretreatment characteristic found to have a significant effect on overall survival. Severe or greater toxicity occurred in 97% and 89% of the normal and impaired marrow reserve groups, respectively, with granulocytopenia the principal toxicity. Treatment-related fatalities occurred in 8% of patients. m-BACOD is an effective but toxic treatment program for intermediate- and high-grade malignant lymphomas.
Bone marrow involvement by non-Hodgkin's lymphoma: the clinical significance of morphologic discordance between the lymph node and bone marrow. Nebraska Lymphoma Study Group.

Bone marrow specimens from 317 patients with non-Hodgkin's lymphoma (NHL) obtained at initial staging were evaluated for the presence of lymphoma or benign lymphoid aggregates. Thirty-two percent (102 patients) had lymphoma in their bone marrow, and 9% had benign lymphoid aggregates. Bone marrow lymphoma was present in 39% of low-grade, 36% of intermediate-grade, and 18% of high-grade lymphomas. The bone marrow was involved in 25% of patients with diffuse large-cell or immunoblastic NHL (ie, diffuse histiocytic lymphoma of Rappaport). Bone marrow involvement did not affect survival of patients with low-grade NHL, but survival was significantly shorter (P = .03) for patients with intermediate- and high-grade NHL with bone marrow involvement. Bone marrow involvement was equally common in B-cell and T-cell NHL (31% v 32%). However, patients with T-cell NHL and bone marrow involvement had shorter survival than B-cell NHL with marrow involvement (P = .02) or T-cell NHL without marrow involvement (P = .05). A high incidence of morphologic discordance between lymph node and bone marrow was observed (ie, 40%), always with a more aggressive subtype in the lymph node than in the bone marrow. Presence of large-cell lymphoma in the bone marrow predicted for short survival. Survival for patients with small-cell lymphoma in their bone marrow did not differ significantly from patients with negative bone marrows. We conclude that bone marrow involvement in large-cell NHL, especially in those of T-cell origin, portends a poor prognosis. However, the subgroup of patients with an aggressive histologic subtype of NHL in a lymph node biopsy and small-cell NHL in the bone marrow do not have a poorer outlook than those without bone marrow involvement.

The principles of dose-response and combination chemotherapy were basic to the design of the initial curative standard-dose treatment regimens for leukemias, lymphomas, and testis cancer. Agents were selected with different dose-limiting toxicities, resulting in subadditive toxicity in combination. A fourth principle in the design of curative regimens was to combine agents with different mechanisms of action to avoid cross-resistance. Based on these principles, combinations of the highest tolerated doses of active noncross-resistant agents are required to decrease the emergence of drug resistance and achieve optimum cytotoxicity. Hematopoietic stem-cell support provides a mechanism for significantly increasing the doses of active agents, a strategy that has resulted in the cure of 10% to 50% of selected patients with lymphoma who could not be cured with standard-dose therapy. The lack of sufficiently effective cytoreductive conditioning regimens remains the major impediment to improving the high-dose therapy of patients with solid tumors. In this study, 27 patients with solid tumors were treated with a combination of cyclophosphamide, thiotepa, and carboplatin (CTCb) in a phase I-II study. Severe mucositis and neurotoxicity were dose-limiting. The maximum-tolerated dose (MTD) of the combination was 6.0 g/m2 of cyclophosphamide, 500 mg/m2 of thiotepa, and 800 mg/m2 of carboplatin. There were two deaths (7%) of sepsis, and an overall response rate of 72% in refractory tumors (81% in breast cancer). CTCb is a combination with low morbidity and high cytoreductive efficacy designed to exploit the principles of curative cancer chemotherapy.
