PURPOSE

To determine the recommended dose, toxicity profile, and pharmacokinetics of KRN8602 (MX2-hydrochloride), a novel morpholino anthracycline with potent cytotoxicity against anthracycline-sensitive and resistant experimental tumors in vitro and in vivo.

PATIENTS AND METHODS

KRN8602 was administered alone in increasing doses to patients with advanced cancer or high-grade gliomas until dose-limiting toxicity (DLT) was observed in three or more of five patients treated in a dose level. Because neutropenia was dose limiting, further escalation was investigated with filgrastim support.

RESULTS

Fifty-six assessable patients completed at least one cycle of chemotherapy. The recommended dose of KRN8602 alone was 40 mg/m2. Dose escalation was limited by neutropenia. The recommended dose of KRN8602 with filgrastim was 70 mg/m2, and limiting toxicities were neutropenia, diarrhea, and vomiting. The most commonly experienced nonhematologic toxicity was nausea and vomiting. Alopecia and mucositis were infrequent and mild. Pharmacokinetic parameters showed substantial variation, although the area under the plasma concentration-time curve (AUC) and maximum concentration both increased with dose. There was no relationship between pharmacokinetic parameters and toxicity.

CONCLUSION

KRN8602 at doses of 40 mg/m2 when administered alone and 70 mg/m2 when administered with filgrastim appeared to be manageable. The major DLTs were neutropenia and, at higher doses, diarrhea and vomiting. The efficacy of this drug is currently being tested in phase II studies.

PURPOSE

To determine the maximum-tolerated dose (MTD) of paclitaxel administered as a 3-hour infusion in patients with recurrent malignant glioma.

PATIENTS AND METHODS

Patients were stratified by starting dose of paclitaxel and concurrent anticonvulsant (AC) use and were treated in cohorts of three patients. The starting dose was 240 mg/m2 administered intravenously with escalations of 30 mg/m2 until the MTD was established. Pharmacokinetic data were obtained for each patient for the first infusion. Tumor response was assessed at 6-week intervals and treatment was continued until documented tumor progression, unacceptable toxicity, or a total of 12 paclitaxel infusions.

RESULTS

From April 1995 to December 1996, 34 patients were treated; 27 patients in the AC group and seven patients in the non-AC group. The MTD for patients who received ACs was established at 360 mg/m2 and the dose-limiting toxicity (DLT) was central neurotoxicity, characterized as transient encephalopathy and seizures. In contrast, the MTD for patients who did not receive ACs was 240 mg/m2, and myelosuppression, gastrointestinal toxicity, and fatigue were the DLTs. Pharmacokinetic data confirmed that the plasma drug levels and clearance rates were similar for patients in both groups at the respective dose levels that produced DLTs.

CONCLUSION

The pharmacokinetics of paclitaxel are altered by ACs, and significantly larger doses of the drug can be administered to patients with brain tumors on AC therapy. The toxicity profile is different for patients on AC therapy treated at these higher doses. A phase II study has been initiated that uses a dose of 330 mg/m2 for patients on AC therapy and 210 mg/m2 for patients not on AC therapy.

PURPOSE

A growing body of data suggests that local control in nasopharyngeal cancer (NPC) is related to the radiation dose administered. We conducted a single-institution study of high-dose radiotherapy (RT), which incorporated high-dose-rate (HDR) brachytherapy (BT). These results were analyzed together with data obtained from controls who did not receive BT.

PATIENTS AND METHODS

The BT group comprised 42 consecutive patients of whom 29 patients were staged according to the tumor, node, metastasis system as T1 through 3, 13 patients were T4, and 34 patients were N+ disease. BT was administered on an outpatient basis by means of a specially designed flexible nasopharyngeal applicator, and the dose distributions were optimized. Treatment for T1 through 3 tumors comprised 60 Gy of external-beam radiotherapy (ERT) followed by six fractions of 3 Gy BT (two fractions per day). Patients with parapharyngeal tumor extension and/or T4 tumors received 70 Gy ERT and four fractions of 3 Gy BT. The no-BT group consisted of all patients treated from 1965 to 1991 (n = 109), of whom 82 patients had stages T1 through 3, 27 patients had T4, and 80 patients had N+ disease. Multivariate Cox proportional hazards analyses were performed by using the end points time to local failure (TTLF), time to distant failure (TTDF), disease-free survival (DFS), cause-specific survival (CSS), and the prognostic factors age, tumor stage, node stage, and grade. Because the overall treatment time varied substantially in the no-BT group, the dependence of local failure (LF) on the physical dose as well as the biologic effective dose (BED) corrected for the overall treatment time (OTT) (BEDcor10) was studied.

RESULTS

The BT group had a superior 3-year local relapse-free rate (86% v 60%; univariate analysis, P = .004). Multivariate analysis showed hazards ratios for BT versus no-BT of 0.24 for TTLF (P = .003), 0.35 for TTDF (P = .038), 0.31 for DFS (P < .001), and 0.44 for CSS (P = .01). The best prognostic group consisted of patients with T1 through 3, N0 through 2b tumors treated with BT who attained a 5-year TTLF of 94% and CSS of 91%. In contrast, the worst prognostic group, i.e., 5-year TTLF of 47% and CSS of 24%, was composed of patients with T4 and/or N2c through 3 tumors who did not receive BT.

CONCLUSION

High doses of radiation (73 to 95 Gy) can be administered to patients with NPC with minimal morbidity by means of optimized HDR-BT. The use of a BT boost proved to be of significant benefit, particularly in patients with T1 through 3, N0 through 2b disease. The steep dose-effect relationship seen for the physical dose and the BEDcor10 indicates that the results are dose related. The analysis has identified a poor prognostic group in whom treatment intensification with chemotherapy (CHT) is indicated.

Published: February 2017

PURPOSE

To determine the patterns of recurrence and causes of regional nodal basin failure in stage I or II melanoma patients who had a histologically negative sentinel lymph node (SLN) and whose regional nodal basins were not dissected following lymphatic mapping and SLN biopsy.

PATIENTS AND METHODS

The records of 344 patients with primary cutaneous melanoma who underwent lymphatic mapping and SLN biopsy between 1991 and 1995 at The University of Texas M.D. Anderson Cancer Center were reviewed. Of 322 patients who underwent successful lymphatic mapping procedures, 270 had histologically negative SLNs; mapped nodal basins were observed without further surgical intervention in 243 of these 270 patients. Recurrence patterns were analyzed from this cohort and a histologic reevaluation of all previously identified SLNs on which a biopsy had been taken was performed in patients who developed recurrent disease.

RESULTS

Of 243 patients with a histologically negative SLN, 27 (11%) developed local, in-transit, regional nodal, and/or distant metastases after a median follow-up time of 35 months. Ten patients (4.1%) developed a nodal recurrence in the previously mapped basin, either solely or as a component of the first site of recurrence. Detailed analysis of the SLNs in these 10 patients demonstrated evidence of occult metastases in 80% by serial sectioning or immunohistochemical staining.

CONCLUSION

Regional nodal failures in melanoma patients following a negative SLN biopsy are infrequent and to date have most commonly occurred because conventional histologic evaluation was unable to identify occult metastatic disease. These data provide further evidence that lymphatic mapping and SLN biopsy accurately reflect the status of the regional nodal basin. Specialized pathologic techniques are necessary to reduce further the already low false-negative rates and to improve disease staging.
Prostate-specific antigen doubling times are similar in patients with recurrence after radical prostatectomy or radiotherapy: a novel analysis.

Published: February 2017

PURPOSE

Some investigators have analyzed the rate of growth of prostate cancer that has recurred after definitive radiotherapy or radical prostatectomy using serum prostate-specific antigen (PSA) doubling times (DT). We examined all PSA values in recurrent patients to determine the pattern and rate of increase in PSA after radiation therapy and radical prostatectomy.

PATIENTS AND METHODS

Charts of 96 recurrent radical prostatectomy patients (mean age, 62.8 years; range, 47 to 76) and 42 recurrent radiation therapy patients (mean age, 67.2 years; range, 52 to 83) were reviewed. All available PSA values between the date of operation/radiation treatment and last follow-up evaluation or the initiation of second-line therapy are included. Rate of PSA DT was not assumed to be constant over time; it was instead allowed to vary. We use a piecewise linear random-coefficients model in time for log (PSA), which allowed different mean models for both treatments.

RESULTS

The PSA DT in the first year after radiation therapy was--1.17 years, which reflects the continuous decline in PSA in the average patients during the first year after radiotherapy despite eventual biochemical progression. In contrast, the PSA DT in the radical prostatectomy group was 0.66 in the first year. In year 2, after radiation therapy, the PSA DT was lengthy at 1.82 years, significantly longer (P = .0025) than in the radical prostatectomy group (0.76 years). After year 2, there were no significant differences between the two groups (P > .05).

CONCLUSION

A piecewise linear random-coefficients model enables interval analysis of PSA DT. While the PSA DT after radiation therapy and radical prostatectomy are different in the first 2 years, the rate of increase in PSA appears to be similar in the two groups after year 2, which suggests the rate of growth of cancers that recur after radiation therapy and radical prostatectomy is similar.

Published: February 2017

PURPOSE

Hot flashes can be a prominent clinical problem for breast cancer survivors and men who undergo androgen-deprivation therapy. Anecdotal information suggested a low dose of a relatively new antidepressant, venlafaxine, could abrogate this clinical problem.

MATERIALS AND METHODS

This study included 28 consecutive assessable patients entered onto a phase II clinical trial. Hot flash data were collected by daily diary questionnaires during a 1-week baseline period and then for 4 weeks, during which time patients received venlafaxine 12.5 mg orally twice daily.

RESULTS

Fifty-eight percent of patients who completed the study had a greater than 50% reduction in hot flash scores (frequency times severity) during the fourth treatment week as compared with the baseline week. Median weekly hot flash scores were reduced by 55% from baseline during the fourth week of venlafaxine therapy. Therapy was generally well tolerated and appeared to alleviate fatigue, sweating, and trouble sleeping.

CONCLUSION

Venlafoxine appears to represent an efficacious new method to alleviate hot flashes. Further evaluation of this compound for alleviating hot flashes is indicated.

Published: February 2017

PURPOSE

Patients with palpable extraprostatic disease (T3) have a poor prostate-specific antigen (PSA) failure-free (bNED) survival rate after radical prostatectomy (RP) or external-beam radiation therapy (RT). This study was performed to validate or refute the prognostic value of the previously defined calculated prostate cancer volume (cV(Ca)).

PATIENTS AND METHODS

For patients with clinically localized disease (T1c,2), a Cox regression multivariable analysis was used to assess the ability of the cV(Ca) value to predict time to posttherapy PSA failure following RP or RT.

RESULTS

The cV(Ca) value was a significant predictor (P < or = .0005) of time to posttherapy PSA failure in both an RP and RT data set independent of the one used to derive the cV(Ca)-based clinical staging system. In both RP- and RT-managed patients, estimates of 3-year bNED survival were not statistically different for patients with either T1c,2 disease and a cV(Ca) greater than 4.0 cm3 (RP, 27%; RT, 18%) or T3 disease (RP, 37%; RT, 34%). Despite pathologic T2 disease, the 3-year estimate of bNED survival was at most 51% in RP-managed patients with T1c,2 disease and cV(Ca) greater than 4.0 cm3.

CONCLUSION

A cV(Ca) greater than 4.0 cm3 identified patients with T1c.2 disease whose bNED survival was poor after RT or RP despite pathologic T2 disease that suggests the presence of occult micrometastatic disease in many of these patients. Prospective randomized trials to evaluate the impact on survival of adjuvant systemic therapy in these high-risk patients are justified.
Prospective Randomized Trial of Melphalan and Prednisone Versus Vincristine, Carmustine, Melphalan, Cyclophosphamide, and Prednisone in the Treatment of Primary Systemic Amyloidosis

Published: February 2017

PURPOSE: Primary systemic amyloidosis is an immunoglobulin deposition disorder in which insoluble light chains cause organ dysfunction and death. The established conventional therapy is treatment with melphalan and prednisone. We investigated whether treatment with multiple alkylating agents improved the response rate or survival time, compared with melphalan and prednisone therapy.

PATIENTS AND METHODS: We treated 101 patients with biopsy-proven primary amyloidosis. The patients were randomly assigned to receive melphalan and prednisone (52 patients) or vincristine, carmustine, melphalan, cyclophosphamide, and prednisone (49 patients). Patients were stratified according to the presence of cardiac involvement, time from diagnosis to randomization, serum beta2-microglobulin level, and whether peripheral neuropathy was the major manifestation of the disease.

RESULTS: The median duration of survival after randomization was 29 months, with no differences in survival time between the two groups. There were 29 patients who fulfilled the response criteria: 15 in the vincristine, carmustine, melphalan, cyclophosphamide, and prednisone arm and 14 in the melphalan and prednisone arm.

CONCLUSION: Therapy with multiple alkylating agents did not result in a higher response rate or longer survival time, compared with standard melphalan and prednisone treatment in patients with primary systemic amyloidosis.
Randomized Phase III Trial Comparing the New Potent and Selective Third-Generation Aromatase Inhibitor Vorozole With Megestrol Acetate in Postmenopausal Advanced Breast Cancer Patients
Authors: Goss P. E. , Winer E. P. , Tannock I. F. , Schwartz on behalf of the North American Vorozole Study Grou L. H.
Published: February 2017

PURPOSE: To compare the efficacy and safety of vorozole (VOR) 2.5 mg once daily with that of megestrol acetate (MA) 40 mg four times per day as second-line therapy in postmenopausal women with advanced breast cancer whose disease progressed after tamoxifen treatment.

PATIENTS AND METHODS: A total of 452 patients were enrolled onto an open, multicenter, randomized phase III trial comparing VOR to MA for tumor response, safety, and quality of life (as indicated by the Functional Living Index-Cancer score).

RESULTS: Vorozole produced a response rate of 9.7%, compared with 6.8% for MA (P = .24). Clinical benefit (complete response + partial response + no change in > 6 months) was demonstrated in 23.5% and 27.2% of patients treated with VOR and MA, respectively (P = .42). Median duration of response was 18.2 months for VOR versus 12.5 months for MA (P = .074). There was no significant difference in time to progression or survival between the treatment groups. Discontinuation of treatment because of adverse events occurred less frequently in the VOR-treated group (3.1% v 6.2%; P = .18). Patients on the VOR arm reported significantly more nausea, hot flushes, arthralgia, upper respiratory tract infection, anorexia, and paresthesia, whereas those treated with MA had significantly more dyspnea, increased appetite, and weight increase. There was no difference between the two treatment groups in Functional Living Index-Cancer scores (total or subscales). However, when analyzed by objective response, patients with complete or partial responses (P = .032) or no change (P = .033) who were receiving VOR had significant improvement in the psychologic well-being subscale, compared with patients given MA.

CONCLUSION: Vorozole is well tolerated and as effective as MA in the treatment of postmenopausal advanced breast cancer patients with disease progression after tamoxifen treatment.

Published: February 2017

PURPOSE: To evaluate the efficacy and toxicity of combination and sequential dose-dense chemotherapy with doxorubicin and docetaxel (Taxotere; Rhône-Poulenc Rorer, Collegeville, PA) as primary chemotherapy of breast cancer.

PATIENTS AND METHODS: Patients with newly diagnosed stage II or noninflammatory stage III breast cancer were randomly assigned to receive the same total doses of doxorubicin and docetaxel over a 12-week period before definitive surgery. Patients in arm A received sequential therapy with doxorubicin 75 mg/m2 every 2 weeks for three cycles followed by docetaxel 100 mg/m2 every 2 weeks for three cycles. Patients in arm B received combination therapy with doxorubicin 56 mg/m2 plus docetaxel 75 mg/m2 every 3 weeks for four cycles. Granulocyte colony-stimulating factor was administered on days 2 to 12 of each cycle in both groups.

RESULTS: Forty patients were entered onto the trial. Pretreatment tumor size averaged 5.7 cm with clinicallypositive axillary lymph nodes in 23 patients (57%). As expected, myelosuppression was severe in both groups; however, ≥ 80% of planned dose-intensity was delivered. Hand-foot syndrome was more common after sequential therapy. Clinical responses were similar in both groups, with an overall response rate of 87%, including 20% clinical complete remissions. Pathologic complete remission or residual in situ disease only was confirmed in five patients (12.8%). Patients who received sequential therapy had fewer positive lymph nodes (mean, 2.17 v 4.81; P < .037) at definitive surgery.

CONCLUSION: Primary chemotherapy with doxorubicin and docetaxel is well tolerated and highly active. A sequential treatment schedule increases toxicity but may result in more substantial lymph node clearance than combination therapy.
Treatment of Locally Advanced Prostate Cancer: Is Chemotherapy the Next Step?
Authors: Oh William K. , Kantoff Philip W.
Published: February 2017

PURPOSE: Management of locally advanced prostate cancer remains controversial. Various single and combination modality approaches have been advocated, but an accepted standard of care remains undefined. The purpose of this review is to define the current knowledge in managing locally advanced prostate cancer and to propose new treatment approaches based on current knowledge.

MATERIALS AND METHODS: A MEDLINE search to detect all relevant articles on the management of locally advanced prostate cancer was performed. A review of the staging, natural history, and prognosis of this disease was also performed.

RESULTS: The lack of a clearly defined treatment approach to patients with locally advanced prostate cancer stems from multiple factors, including ambiguities in clinical staging, inadequate knowledge of the natural history of the cancer, and a dearth of comparative randomized trials evaluating efficacy of different therapies. Single modality treatment, including radical prostatectomy (RP) or external-beam radiotherapy alone, is associated with high rates of failure. The use of adjuvant hormonal ablation therapy in combination with external-beam radiotherapy has shown improvement in progression-free and overall survival, although similar improvements have not been clearly demonstrated for surgical patients treated with hormonal therapy. New advances in chemotherapy for hormone-refractory prostate cancer suggest that response rates may be as high as 50% or more, and current trials are evaluating the addition of chemotherapy to hormonal ablation in either surgery or radiation therapy in locally advanced prostate cancer.

CONCLUSION: Optimal management of locally advanced prostate cancer remains undefined. Standard treatment options include RP, external-beam radiotherapy, or hormonal ablation therapy, alone or in combination. New approaches being tested include improved methods for delivering radiation or combining hormonal ablation with surgery or radiation. It is possible that other forms of systemic therapy, including chemotherapy, may become important components of multimodality treatment. Clinical trials designed to test this hypothesis are ongoing.

Published: February 2017

PURPOSE: To evaluate the efficacy and toxicity of the combination of carboplatin, docetaxel, and gemcitabine in patients with advanced non–small-cell lung cancer (NSCLC).

PATIENTS AND METHODS: Forty-five chemotherapy-naive patients with NSCLC were treated on an out-patient basis with carboplatin area under the curve 5 intravenous (IV) and gemcitabine 800 mg/m2 IV on day 1 and docetaxel 75 mg/m2 IV and gemcitabine 800 mg/m2 IV on day 8. Granulocyte colony-stimulating factor (150 ug/m2 subcutaneously) was given prophylactically from day 3 to day 6 and day 10 to day 16. Chemotherapy was repeated every 4 weeks. Patients were evaluated for response every two cycles of treatment.

RESULTS: The median age of the patients was 58 years (range, 24 to 75 years). The performance status was 0 for 16 patients, 1 for 17 patients, and 2 for 12 patients. Nine patients (20%) had stage IIIB disease, and 36 (80%) had stage IV; histology was mainly squamous cell carcinoma (51.2% of patients) that was poorly differentiated (37.8%). All 45 patients were assessable for toxicity, and 41 were assessable for response. On an intent-to-treat analysis, the objective response rate was 46.5% (21 out of 45 patients; 95% confidence interval [CI], 31.7% to 62.5%). Of the 45 patients, four (8.8%) achieved a complete response (95% CI, 2.5% to 21.2%); 17 (37.7%) achieved a partial response (95% CI, 23.8% to 53.5%); seven (15.5%) had stable disease; and 14 (31.1%) had progressive disease. The median survival time was 13.5 months, and the actuarial 1-year survival rate was 51.11%. The median duration of response was 7.6 months, and the time to tumor progression was 8.1 months. Grade 3/4 anemia and thrombocytopenia occurred in 17.7% and 28.8% of patients, respectively. Twenty-one patients (46.6%) developed grade 3/4 neutropenia, and six patients (13.3%) were complicated with fever. Alopecia was universal. Grade 3 diarrhea occurred in four patients (8.8%); grade 3/4 neurotoxicity occurred in 10 patients (22.2%); and grade 2/3 allergic reaction occurred in three patients (16.6%). There were no treatment-related deaths. Six patients (13.3%) required a dose reduction, two of which required two reductions.

CONCLUSIONS: The combination of carboplatin, docetaxel, and gemcitabine is an effective regimen for the treatment of chemotherapy-naive patients with advanced NSCLC, causing only moderate toxicity.
Phase II Trial of Doxorubicin and Paclitaxel Plus Granulocyte Colony-Stimulating Factor in Metastatic Breast Cancer: An Eastern Cooperative Oncology Group Study
Authors: Sparano Joseph A. , Hu Ping , Rao Radha M. , Falkson Carla I. , Wolff Antonio C. , Wood William C.
Published: February 2017

PURPOSE: Several groups have reported that the combination of doxorubicin plus paclitaxel given as a 3-hour intravenous (IV) infusion for up to eight cycles produces a high response rate (> 80%) and complete response rate (> 20%) in metastatic breast cancer, but is also complicated by a 20% incidence of congestive heart failure (CHF). The purpose of this phase II trial was to evaluate the antineoplastic activity of the regimen in a multi-institutional setting and to reduce the incidence of cardiotoxicity by limiting treatment to a maximum of six cycles.

PATIENTS AND METHODS: Fifty-two patients with advanced breast cancer received doxorubicin (60 mg/m2 by IV injection) followed 15 minutes later by paclitaxel (200 mg/m2 by IV infusion over 3 hours) every 3 weeks for four to six cycles.

RESULTS: Objective responses occurred in 25 of 48 assessable patients (52%; 95% confidence interval [CI], 38% to 66%), including four complete responses (8%; 95% CI, 0% to 16%). The median cumulative doxorubicin dose given was 240 mg/m2 (range, 132 to 360 mg/m2). Eleven patients (21%) were documented as having a decrease in the LVEF below normal, including three patients (6%; 95% CI, 0% to 12%) who developed CHF.

CONCLUSION: The doxorubicin/paclitaxel regimen that we used is unlikely to produce an objective response rate of more than 70% and a complete response rate of more than 20% in patients with metastatic breast cancer, and proved to be excessively cardiotoxic for use in the adjuvant setting.

PURPOSE: To evaluate the activity and toxicity of the combination of cisplatin (80 mg/m2 day 1) and vinorelbine (25 mg/m2 days 1 and 8) in patients with carcinoma of the uterine cervix that has not been previously treated with chemotherapy.

PATIENTS AND METHODS: Fifty patients with cervical cancer were enrolled onto this study (27 stage IB-III, 23 stage IVB-recurrent). A two-stage optimal Simon design was applied. Thirteen responders of 29 treated patients were required to proceed beyond the first stage, and 28 responders were needed overall.

RESULTS: Hematologic toxicity was mild, with neutropenia being the most frequent side effect. Nonhematologic toxicity was frequent but never severe; one patient had grade 3 peripheral neurotoxicity. Objective responses were recorded for 32 patients (64%): 11 patients (22%) achieved a complete response (CR) and 21 patients (42%) achieved a partial response (PR). The response rate was 81.5% in patients with IB-III stage (25.9% CR rate) and 43.5% in patients with IVB-recurrent disease (17.4% CR rate). Responses were seen both in stage IVB patients (one CR and two PRs, for an overall rate of 37.5%) and in patients with recurrent disease (three CRs + four PRs, for an overall rate of 46.7%).

CONCLUSION: The combination of cisplatin and vinorelbine is an active regimen in the treatment of patients with early-stage and advanced carcinoma of the uterine cervix. The hematologic and nonhematologic toxicity of this combination is mild.

PURPOSE: Whether recent improvements in the treatment of childhood acute lymphoblastic leukemia (ALL) have nullified the adverse prognosis associated with male sex remains unclear. Therefore, we analyzed the survival experience and presenting clinical and laboratory features of boys and girls with newly diagnosed ALL who were treated at our institution over the past three decades.

PATIENTS AND METHODS: One thousand one hundred fifty-one boys and 904 girls were treated in 13 consecutive Total Therapy studies between 1962 and 1994. An overview analysis was used to investigate the impact of sex on overall and event-free survival, both for the entire cohort and for subgroups defined by treatment era and blast-cell immunophenotype. Stratified analyses were performed to adjust for treatment protocol and known risk factors, and in the modern treatment era, for protocol, immunophenotype, and the DNA content of leukemic cells (ie, DNA index). The pharmacokinetics of methotrexate, teniposide, and cytarabine, as well as the thiopurine methyltransferase activity of erythrocytes, were compared between boys and girls treated on a single protocol.

RESULTS: Compared with girls, boys were more likely to have T-cell ALL (20.9% v 10.7%, P < .001) and seemed less likely to have a favorable DNA index (17.8% v 25.1%, P = .072). There were no other statistically significant differences between the two sexes with respect to presenting features, including leukemic-cell genetic abnormalities, nor were there significant sex differences in the pharmacokinetics of methotrexate, teniposide, or cytarabine or in erythrocyte thiopurine methyltransferase activity. Girls clearly fared better than boys (P < .001) on protocols used during the early era of treatment (10-year event-free survival ± 1 SE, 43.1% ± 2.1% v 31.5% ± 1.7%). Although prognosis improved for both sexes in the modern era, the difference in outcome between girls and boys persisted (P = .025) (10-year event-free survival, 73.4% ± 3.7% v 63.5% ± 4.0%). However, stratification of modern-era patients by protocol, immunophenotype, and DNA index mitigated statistical evidence of a sex difference in overall survival (P = .263) and event-free survival (P = .124).

CONCLUSION: Although boys and girls alike have benefited from improvements in ALL therapy, these gains have not completely eliminated the sex difference in prognosis that has persisted since the early 1960s. The apparent difference in outcome is partially explained by differences between boys and girls in the distributions of ALL immunophenotype and DNA index.

PATIENTS AND METHODS: Thirty-six patients with metastatic colorectal cancer, who progressed while receiving or within 6 months after discontinuing palliative chemotherapy with fluoropyrimidines/leucovorin, were enrolled onto this study. Treatment consisted of oxaliplatin 85 mg/m2 on days 1 + 15 and irinotecan 80 mg/m2 on days 1 + 8 + 15 every 4 weeks. Depending on the absolute neutrophil counts (ANC) on the day of scheduled chemotherapeutic drug administration, a 5-day course of granulocyte colony-stimulating factor (G-CSF) 5 μg/kg/d was given.

RESULTS: The overall response rate was 42% for all 36 assessable patients (95% confidence interval, 26% to 59%), including two complete remissions (6%). Thirteen additional patients (36%) had stable disease, and only eight (22%) progressed. The median time to treatment failure was 7.5 months (range, 1 to 13.5+ months). After a median follow-up time of 14 months, 19 patients (53%) are still alive. Hematologic toxicity was commonly observed, although according to the ANC-adapted use of G-CSF (in 31 patients during 81 of 174 courses), it was generally mild: grade 3 and 4 granulocytopenia occurred in only five and two cases, respectively. The most frequent nonhematologic adverse reactions were nausea/emesis and diarrhea, which were rated severe in 17% and 19%, respectively.

CONCLUSION: Our data suggest that the combination of irinotecan and oxaliplatin with or without G-CSF has substantial antitumor activity in patients with progressive fluoropyrimidine/leucovorin-pretreated colorectal cancer. Overall toxicity was modest, with gastrointestinal symptoms constituting the dose-limiting side effects. Further evaluation of this regimen seems warranted.

PURPOSE: To evaluate alternative automated methods of collecting data on quality of life (QOL) in cancer patients. After initial evaluation of a range of technologies, we compared computer touch-screen questionnaires with paper questionnaires scanned by optical reading systems in terms of patients' acceptance, data quality, and reliability.

PATIENTS AND METHODS: In a randomized cross-over trial, 149 cancer patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Core 30, version 2.0 (EORTC QLQ-C30), and the Hospital Anxiety and Depression Scale (HADS) on paper and on a touch screen. In a further test-retest study, 81 patients completed the electronic version of the questionnaires twice, with a time interval of 3 hours between questionnaires.

RESULTS: Fifty-two percent of the patients preferred the touch screen to paper; 24% had no preference. The quality of the data collected with the touch-screen system was good, with no missed responses. At the group level, the differences between scores obtained with the two modes of administration of the instruments were small, suggesting equivalence for most of the QOL scales, with the possible exception of the emotional, fatigue, and nausea/vomiting scales and the appetite item, where patients tended to give more positive responses on the touch screen. At the individual patient level, the agreement was good, with a kappa coefficient from 0.57 to 0.77 and percent global agreement from 61% to 97%. The electronic questionnaire had good test-retest reliability, with correlation coefficients between the two administrations from 0.78 to 0.95, kappa coefficients of agreement from 0.55 to 0.90, and percent global agreement from 56% to 100%.

CONCLUSION: Computer touch-screen QOL questionnaires were well accepted by cancer patients, with good data quality and reliability.

PURPOSE: The prognosis of osteosarcoma occurring as a second malignant disease (OS-SMD) is thought to be poor. We attempted to evaluate whether this holds true when OS-SMD is treated with combined modality therapy as developed for primary osteosarcoma and if factors that influence survival might be identified.

PATIENTS AND METHODS: All patients with OS-SMD registered at the Cooperative German-Austrian-Swiss Osteosarcoma Study Group (COSS) study center between 1980 and June 1996 were evaluated for patient- and treatment-related factors, local and systemic outcome, and survival. Therapy was to be given according to contemporary COSS protocols for primary extremity osteosarcoma, including surgery and multiagent chemotherapy.

RESULTS: Thirty patients with OS-SMD were registered (median latency period, 9 years 2 months). The first malignancies had been retinoblastoma (10 patients), sarcoma (10 patients), lymphoma (five patients), carcinoma (four patients), and medulloblastoma (one patient). Treatment for these malignancies had included radiotherapy in 24 patients, surgery in 20, and chemotherapy in 14. Twelve osteosarcomas were located axially and 18 were located in an extremity; 17 were radiation-related. Twenty-seven patients presented with localized disease; three presented with primary metastases (two skip, one lung). All 30 patients received chemotherapy, 29 with multiple drugs. Twenty-eight patients underwent operation. At 7 years, actuarial overall survival, survival free from osteosarcoma progression, and survival free from progression of any cancer were 50%, 34%, and 30%, respectively. In 24 patients with local tumor control, the corresponding values were 63%, 46%, and 38%. All seven local failures occurred in patients with axial osteosarcomas who did not undergo operation with wide surgical margins.

CONCLUSION: Provided that local tumor control is achieved, OS-SMD treated with combined modality therapy may have a prognosis that approaches that of otherwise comparable primary osteosarcoma.

Published: February 2017

PURPOSE AND METHODS: The ability of granulocyte colony-stimulating factor (G-CSF) plus erythropoietin (EPO) treatment was compared in a randomized fashion with that of G-CSF treatment alone in promoting hematologic recovery and peripheral-blood progenitor-cell (PBPC) mobilization in previously untreated patients with advanced ovarian cancer who underwent their first course of epirubicin, paclitaxel, and cisplatin (ETP) chemotherapy during a phase II study of intensive outpatient ETP chemotherapy followed by high-dose carboplatin, etoposide, and melphalan (CEM) late intensification with PBPC support.

RESULTS: Comparative analysis of hematologic recovery of 50 randomized patients, after ETP chemotherapy, showed that life-threatening neutropenia occurred in 88% of the patients treated with G-CSF alone, whereas it occurred in only 4% of patients treated with G-CSF + EPO. Significantly different WBC and polymorphonuclear leukocyte (PMN) counts were observed in the two distinct arms on the day of WBC nadir (P < .0001 and P < .0001, respectively). Moreover, the addition of EPO to G-CSF increased PBPC mobilization and collection as compared with that in G-CSF–treated patients (P = .0009 and P = .0026, respectively), who required a significantly higher number of leukaphereses than G-CSF + EPO–treated patients (P = .0076) to obtain the planned minimum dose of PBPCs. Qualitative analysis by cloning assay of PBPCs collected in both arms revealed that G-CSF– and G-CSF + EPO–mobilized PBPCs have comparable in vitro functional properties.

CONCLUSION: This randomized comparison revealed that EPO significantly increases most of the hematologic effect produced by G-CSF administration after chemotherapy. This biologic property of EPO translated in vivo into a global improvement of patients' hematologic status.

PURPOSE: Two phase I studies of the oxaliplatin and irinotecan combination were performed in advanced gastrointestinal cancer patients to characterize the safety and pharmacokinetics of the regimen.

PATIENTS AND METHODS: Patients with a performance status (PS) of ≤2 and normal hematologic, hepatic, and renal functions received oxaliplatin (2-hour intravenous infusion) followed 1 hour later by irinotecan administered over a 30-minute period, every 3 weeks. Dose levels that were explored ranged from 85 to 110 mg/m2 for oxaliplatin and 150 to 250 mg/m2 for irinotecan. Plasma pharmacokinetics of total and ultrafiltrable platinum, irinotecan, SN-38, and its glucuronide, SN-38G, were determined.

RESULTS: Thirty-nine patients with gastrointestinal carcinomas (24 with colorectal cancer [CRC], four with pancreas cancer, four with gastric cancer, three with hepatocarcinoma, and four with other) received 216 treatment cycles. Median age was 54 years (range, 21 to 72 years); 95% had PS of 0 to 1; all but six had failed fluorouracil (5-FU) chemotherapy. The maximum-tolerated dose was oxaliplatin 110 mg/m2 plus irinotecan 200 mg/m2 in one study and oxaliplatin 110 mg/m2 plus irinotecan 250 mg/m2 in the other study. Grade 3 to 4 diarrhea and febrile neutropenia were dose-limiting toxicities; other toxicities included emesis and dose-cumulative neuropathy. Recommended dose for phase II studies is oxaliplatin 85 mg/m2 and irinotecan 200 mg/m2. At this dose (12 patients, 65 cycles), grade 3 and 4 toxicities per patient included the following: emesis in 42% of patients, neutropenia in 33% (febrile episodes in 17%), peripheral neuropathy in 25%, delayed diarrhea in 17%, and thrombocytopenia in 8%. Two patients with Gilbert's syndrome experienced severe irinotecan toxicity. No plasmatic pharmacokinetic interactions were detected. Seven partial responses were observed in 24 CRC patients.

CONCLUSION: This combination is feasible, with activity in 5-FU–resistant CRC patients. Phase I studies that explore the every-2-weeks schedule, in addition to phase II studies of this schedule (as well as in combination with 5-FU) as second-line therapy of metastatic CRC, are ongoing.

PURPOSE: All cooperative group studies performed in North America for patients with extensive-stage small-cell lung cancer (SCLC) were evaluated to determine the pattern of the clinical trials and the outcome of patients over the past 20 years.

PATIENTS AND METHODS: Phase III trials for patients with extensive-stage SCLC were identified through a search of the National Cancer Institute Cancer Therapy Evaluation Program database from 1972 to 1993. Patients with extensive-stage SCLC treated during a similar time interval listed in the Surveillance, Epidemiology, and End Results (SEER) database were also examined. Trends were tested in the number of trials over time, the number and sex of patients entered onto the trials, and the survival time of patients treated over time.

RESULTS: Twenty-one phase III trials for patients with extensive-stage SCLC were initiated between 1972 and1990. The median of the median survival times of patients treated on the control arms of the phase III trials initiated between 1972 and 1981 was 7.0 months; for those patients enrolled onto control arms between 1982 and 1990, the median survival time was 8.9 months (P = .001). Analysis of the SEER database of patients with extensive-stage SCLC over the same time period shows a similar 2-month prolongation in median survival time.

CONCLUSION: Analysis of 21 phase III trials initiated in North America and the SEER database from 1972 to 1994 demonstrates that there has been a modest improvement in the survival time of patients with extensive-stage SCLC.

PURPOSE: To determine the maximum-tolerated dose (MTD), dose-limiting toxicities (DLT), and pharmacokinetics of 9-aminocamptothecin (9-AC) in a colloidal dispersion (CD) formulation administered as a 30-minute intravenous (IV) infusion over 5 consecutive days every 3 weeks.

PATIENTS AND METHODS: Patients with solid tumors refractory to standard therapy were entered onto the study. The starting dose was 0.4 mg/m2/d. The MTD was assessed on the first cycle and was defined as the dose at which ≥ two of three patients or ≥ two of six patients experience DLT. Pharmacokinetic measurements were performed on days 1 and 5 of the first cycle and on day 4 of subsequent cycles using high-performance liquid chromatography.

RESULTS: Thirty-one patients received 104+ treatment courses at seven dose levels. The DLT was hematologic. At a dose of 1.3 mg/m2/d, three of six patients experienced grade 3 thrombocytopenia. Grade 4 neutropenia that lasted less than 7 days was observed in four patients. At a dose of 1.1 mg/m2/d, four of nine patients had grade 4 neutropenia of brief duration, which was not dose limiting. Nonhematologic toxicities were relatively mild and included nausea/vomiting, diarrhea, obstipation, mucositis, fatigue, and alopecia. Maximal plasma concentrations and area under the concentration-time curve (AUC) increased linearly with dose, but interpatient variation was wide. Lactone concentrations exceeded 10 nmol/L, the threshold for activity in preclinical tumor models, at all dose levels. Sigmoidal Emax models could be fit to the relationship between AUC and the degree of hematologic toxicity. A partial response was observed in small-cell lung cancer.

CONCLUSION: 9-AC CD administered as a 30-minute IV infusion daily times 5 every three weeks is safe and feasible. The recommended phase II dose is 1.1 mg/m2/d.
