PURPOSE To evaluate the feasibility of escalating doses of the topoisomerase I (topo I) inhibitor topotecan (TPT) with granulocyte colony-stimulating factor (G-CSF) in minimally pretreated adults with solid tumors and to study whether G-CSF scheduling variably affects the ability to escalate TPT doses. MATERIALS AND METHODS Thirty-six patients received 121 courses of TPT as a 30-minute infusion daily for 5 days every 3 weeks at doses that ranged from 2.0 to 4.2 mg/m2/d. G-CSF 5 microg/kg/d subcutaneously (SC) was initiated concurrently with TPT (starting on day 1). Because the concurrent administration of TPT and G-CSF resulted in severe myelosuppression at the lowest TPT dose level, an alternate posttreatment G-CSF schedule in which G-CSF dosing began after TPT (starting on day 6) was subsequently evaluated. Plasma sampling was performed to characterize the pharmacologic behavior of high-dose TPT and to determine whether G-CSF altered the pharmacokinetic profile of TPT. RESULTS Severe myelosuppression precluded the administration of TPT at the first dose, 2.0 mg/m2/d, with G-CSF on the concurrent schedule. However, dose escalation of TPT with G-CSF on a posttreatment schedule proceeded to 4.2 mg/m2/d. The dose-limiting toxicities (DLTs) were thrombocytopenia and neutropenia. One partial response was noted in a patient with colorectal carcinoma refractory to fluoropyrimidines. Pharmacokinetics were linear within the dosing range of 2.0 to 3.5 mg/m2/d, but TPT clearance was lower at the 4.2-mg/m2/d dose level. At 3.5 mg/m2/d, which is the maximum-tolerated dose (MTD) and recommended dose for subsequent-phase studies of TPT with G-CSF, the area under the concentration-versus-time curves (AUCs) for total TPT and lactone averaged 2.2- and 2.3-fold higher, respectively, than the AUCs achieved at the lowest TPT dose, 2.0 mg/m2/d. The pharmacologic behavior of high-dose TPT was not significantly altered by the scheduling of G-CSF. CONCLUSION G-CSF administered after 5 daily 30-minute infusions of TPT permits a 2.3-fold dose escalation of TPT above the MTD in solid-tumor patients, whereas concurrent therapy with G-CSF and TPT results in severe myelosuppression.

PURPOSE We examined the impact of age on outcomes in patients with cancer undergoing autologous bone marrow transplantation (ABMT). PATIENTS AND METHODS All 506 adult patients who underwent ABMT at the Johns Hopkins Oncology Center between January 1987 and January 1994 were studied. A total of 405 patients were aged 18 to 49 years and 101 were aged > or = 50. The effect of age and other prognostic variables on transplant-related mortality (TRM), relapse, and event-free survival rates were analyzed. RESULTS Patients aged > or = 50 years has a 2.24-fold increased risk of TRM. Although relapse rates were not different based on age, the increased TRM rate resulted in a slight decrease in overall event-free survival in the older patients. Causes of death were not different by age and were mainly related to preparative regimen toxicity. Length of hospital stay and hospitalization costs were not increased in the older patients. CONCLUSION While the TRM rate was higher in older patients, relapse rates were not increased. Nearly 25% of older patients were expected to be cured of the disease. These data support the use of ABMT in eligible older patients, at least up to the age of 65.

PURPOSE This phase II study was conducted to evaluate the efficacy and toxicity of moderate-dose (60 mg/m2) docetaxel in Japanese patients with previously untreated advanced (stage IIIB or IV) non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Docetaxel 60 mg/m2 was administered intravenously over 1 to 2 hours to patients with previously untreated stage IIIB or IV NSCLC. Treatment was repeated every 3 weeks. No routine premedication was given. The patients' median age was 67 years (range, 40 to 80). Forty-four patients (59%) had adenocarcinoma and 55 (73%) had stage IV disease. The median Eastern Cooperative Oncology Group (ECOG) performance status (PS) was 1. RESULTS Seventy-five patients were eligible and treated with docetaxel. Fourteen patients (19%) achieved a partial response (PR); response was not significantly affected by histology or clinical stage. The median survival time for all patients was 297 days. The predominant toxicity was neutropenia, with 87% of patients experiencing grade 3 or 4. Febrile neutropenia was seen in eight patients. Hypersensitivity and edema each occurred in only 4% of patients and were easily manageable. There was no possible treatment-related death of acute exacerbation of pneumonitis. CONCLUSION Docetaxel 60 mg/m2 showed significant activity in advanced NSCLC, with a low incidence of hypersensitivity or peripheral edema. Further investigation of this agent in NSCLC is warranted, especially in combination with other active drugs.

PURPOSE Long-term evaluation of the combination of two needle aspiration techniques (NAT) (fine-needle aspiration [FNA] and aspiration needle biopsy [ANB]) in performing an efficient preoperative selection of palpable thyroid nodules. PATIENTS AND METHODS Eight years of extensive use of surgery for the detection of thyroid cancer was compared with 12 years of preoperative selection of by NAT. RESULTS A total of 1,140 operations were performed from 1972 to 1979, and 35 malignant nodules were discovered (3.1%). Five thousand four hundred three patients were examined by NAT from 1980 to 1992; 483 (9%) underwent surgery and 158 malignant nodules were excised. The number of malignant nodules identified by NAT was 166 (eight were not excised) (3.1% of the total population examined). The principal clinical and pathologic features were similar in both groups. ANB yielded a definite benign diagnosis in 88 patients with inadequate FNA findings, it correctly identified four malignant nodules diagnosed as benign by FNA, it showed a macrofollicular component in 115 nodules diagnosed by FNA as microfollicular nodules, and it significantly changed the predictive value of 79 suspicions FNA diagnoses. CONCLUSION Introduction of NAT reduced the number of operations for palpable thyroid nodules from 143 to 40 per year and increased from four to 13 the number of malignant nodules excised without any change in the overall incidence of malignant nodules. The combination of ANB to FNA significantly contributed to the high and efficient preoperative patient selection, principally by reducing the number of indeterminate or suspicious, as well as false-negative, preoperative FNA diagnoses.

PURPOSE We report our experience with simultaneous resection of residual masses above and below the diaphragm in patients with metastatic nomseminomatous germ cell tumor (NSGCT) of the testis. MATERIALS AND METHODS Twenty-four patients underwent simultaneous resection of residual postchemotherapy masses in the retroperitoneum and chest, including three who also had radical neck dissection. All had been heavily pretreated with chemotherapy and five had undergone previous retroperitoneal lymph node dissections (RPLNDs). RESULTS The combined procedure was performed with no mortality and low morbidity. The median length of the procedure was 5 hours 45 minutes, median blood loss 500 mL, and median length of hospital stay 9 days. Complications included one patient with chylous ascites and one with a prolonged air leak, both of which resolved with conservative management. Eighteen patients had similar pathologic findings in all sites: 13 with necrosis only and five with teratoma only. Six patients had discordant pathology in the abdomen and chest, including one with viable tumor in the chest only and two with viable tumor in the abdomen only. The overall actuarial 5-year survival rate for all patients was 79%. CONCLUSION Simultaneous resection of neck, chest, and abdominal residual masses after chemotherapy for germ cell tumors is both a feasible and safe alternative to staged excision in selected patients who require surgical intervention at multiple sites and fulfills the objective of rendering patients disease-free in a single operative procedure.

PURPOSE To compare sequential methotrexate (M) and fluorouracil (F) (M-->F) with surgery (National Surgical Adjuvant Breast and Bowel Project [NSABP] B-13) and cyclophosphamide (C), M, and F with M-->F (NSABP B-19), in patients with estrogen receptor (ER)-negative tumors and negative axillary nodes. PATIENTS AND METHODS A total of 760 patients were randomized to B-13; 1,095 patients with the same eligibility requirements were randomized to B-19. Disease-free survival (DFS), distant disease-free survival (DDFS), and survival were determined using life-table estimates. RESULTS A significant benefit in overall DFS (74% v 59%; P < .001) was demonstrated at 8 years in all B-13 patients who received M-->F (69% v 56% [P = .006] in those <or= 49 years of age, and 81% v 63% [P = .002] in those >or= 50 years). A survival advantage was evident in older patients (89% v 80%; P = .03). In B-19, through 5 years, an overall DFS advantage (82% v 73%; P < .001) and a borderline survival advantage (88% v 85%; P = .06) were evident with CMF. The DFS (84% v 72%; P < .001) and survival (89% v 84%; P = .04) benefits from CMF were greater in women aged <or= 49 years. M-->F or CMF after lumpectomy and breast irradiation resulted in a low probability of ipsilateral breast tumor recurrence (IBTR). In B-13, the frequency of IBTR was 2.6% following M-->F versus 13.4% in women treated by lumpectomy; it was 0.6% following CMF in B-19. Toxicity >or= grade 3 was more frequent among CMF patients in B-19. The age-related difference in CMF benefit was not related to amount of drug received. CONCLUSION M-->F and CMF are effective for node-negative patients with ER-negative tumors. The incidence of local-regional or distant metastases and IBTR decreased after either therapy. The benefit from either therapy was evident in all patients, but the CMF advantage was greater in those <or= 49 years. Because it is less toxic, M-->F may be used in patients with medical problems that would preclude CMF administration.

PURPOSE The ability of interferons (IFNs) to enhance tumor-associated antigen expression may be an important approach to enhance the efficacy of some monoclonal antibody (MAb)-based protocols for tumor diagnosis and/or therapy. The present study was designed to determine whether systemic IFN alpha-2a administration (via the intramuscular [IM] route) could upregulate the expression of tumor-associated glycoprotein-72 (TAG-72) and/or carcinoembryonic antigen (CEA) at histologically confirmed sites of carcinoma. PATIENTS AND METHODS Eighteen patients diagnosed with gastrointestinal (GI) carcinoma received systemic IFN alpha-2a according to four dose schedules. In cohorts I and II, patients received two injections of 3 or 6 x 10(6) U IFN alpha-2a per injection, respectively. Patients in cohorts III and IV received the same doses of IFN alpha-2a, 3 and 6 x 10(6) U, respectively, but three injections were given. Tumor and normal colonic mucosa biopsies were obtained from each patient by endoscopy before IFN alpha-2a and after IFN alpha-2a at surgery. The levels of TAG-72 and CEA expression were measured by (1) immunohistochemistry and reported as percent antigen-positive tumor cells, as well as the relative staining intensity, and (2) a quantitative radioimmunoassay. RESULTS TAG-72 and CEA levels were consistently increased in tumor biopsies taken from patients in cohorts III and IV. For example, of 10 patients treated in cohorts III and IV, eight had enhanced TAG-72 expression when measured either as percentage TAG-72-positive tumor cells or as an increased MAb staining intensity following IFN alpha-2a. CEA expression in tumor biopsies from seven of 10 patients in cohorts III and IV was also elevated following IFN alpha-2a treatment. Quantitative analysis of TAG-72 and CEA levels in tumor biopsies confirmed higher tumor antigen levels following IFN alpha-2a administration. No such increases in TAG-72 or CEA levels were observed in tumor samples taken from patients in cohorts I and II. CEA or TAG-72 expression in samples of histologically confirmed normal colonic mucosa showed little or no change after IFN alpha-2a treatment. CONCLUSION Systemic IFN alpha-2a administration can upregulate TAG-72 and CEA expression at distal tumor sites, which may play an important role in immunodiagnosis and therapy.

PURPOSE To gain insight into the management of non-metastatic neuroblastoma by examining clinical and biologic features of International Neuroblastoma Staging System (INSS) stage 1 tumors. METHODS Patients were staged by both the INSS and the Evans staging system and were evaluated for biologic prognostic factors. Patients with INSS stage 1 received no cytotoxic therapy. The literature was reviewed for clinical and biologic data about INSS stage 1. RESULTS We evaluated 10 consecutive patients (median age, 17.5 months) with INSS stage 1; all remain disease-free (median follow-up duration, > 5 years). Tumors were in the abdomen (n = 6), chest (n = 3), or pelvis (n = 1). Neuroblastoma involved margins of resection in six tumors. Poor-prognostic biologic findings included tumor-cell diploidy (n = 2) and unfavorable Shimada histopathology (n = 2). Two patients were to receive chemotherapy for, respectively, a tumor deemed unresectable and a tumor classified as Evans stage III; second opinions resulted in surgical management alone in each case. Published reports confirm that some INSS stage 1 patients (1) are at risk for overtreatment, and (2) have poor-prognostic biologic findings yet do well. CONCLUSION Surgery alone suffices for INSS stage 1 neuroblastoma, even if biologic prognostic factors are unfavorable, microscopic disease remains after surgery, and tumor size is suggestive of "advanced-stage" status in other staging systems. Attempts to resect regionally confined neuroblastomas should take precedence over immediate use of cytotoxic therapy; otherwise, some patients may receive chemotherapy or radiotherapy unnecessarily.

PURPOSE AND METHODS The European Lung Cancer Working Party (ELCWP) performed a randomized trial with the primary end point to determine if maintenance chemotherapy with 12 courses of etoposide (120 mg/m2 on days 1 and 3) and vindesine (3 mg/m2 on day 3) could improve progression-free survival in small-cell lung cancer (SCLC) patients who responded to six courses of induction chemotherapy with ifosfamide, etoposide, and an anthracycline (doxorubicin or epirubicin). RESULTS Among 235 eligible patients initially registered, 91 were randomized to receive maintenance therapy, including seven patients who were no longer responding. Among 84 randomized responders, progression-free survival was significantly improved (P = .003) by maintenance therapy, with median durations (maintenance v follow-up) of 25 versus 12 weeks after the second randomization, but survival was not significantly increased (P = .10), with median durations of 48 and 38 weeks. However, in a multi-variate analysis that took into account disease extent, maintenance therapy, Karnofsky performance status (PS), and absolute dose-intensity (ADI) of anthracycline given during induction, limited disease (LD) and maintenance were found to be independent positive predictors of survival. CONCLUSION We conclude that maintenance chemotherapy in responding patients is beneficial in SCLC.

PURPOSE The preferred treatment of dermatofibrosarcoma protuberans (DFSP) is wide resection, namely, margins > or = 3 cm beyond the evident disease and histologically negative margins. We assess the success achieved by radiation combined with surgery for positive/close margins or by radiation alone for those tumors that are not resectable for technical/medical reasons. The literature on this point is virtually nonexistent. MATERIALS AND METHODS The outcome of treatment of 18 patients with DFSP by radiation alone (n = 3) and radiation and surgery (n = 15) at the Massachusetts General Hospital was assessed. All of the lesions at the time of the treatment by radiation alone or combined with surgery were less than 10 cm. This was the maximum dimension. The actual tumor volume was much less than indicated by this maximum dimension, as the tumors were usually relatively flat. RESULTS The 10-year actuarial local control rate was determined to be 88%. Local control was realized in the three patients treated by radiation alone, with follow-up periods of > or = 9 years. Among 15 patients treated by radiation and surgery, there have been three local failures; the 10-year actuarial local control rate was 84%. The three local failures occurred in 12 patients whose surgical margins were positive. One of these three local failures developed in the group of two patients whose lesions were scored as grade II. CONCLUSION Radiation in well-tolerated dose schedules is an effective option in the management of patients with DFSP. This appears to be true for radiation alone or postoperatively for margin-positive disease (primary or recurrent).

PURPOSE Paclitaxel has shown significant activity in advanced ovarian cancer. In vitro studies with paclitaxel have suggested that fractionated brief infusion schedules may be more effective than the standard 24-hour infusion. We commenced a phase I evaluation of escalating-dose paclitaxel (40, 50, 60, 80, 100 mg/m2) administered weekly as a 1-hour infusion in patients with recurrent ovarian cancer. All patients had received prior paclitaxel and cisplatin therapy. All patients received standard premedication. PATIENTS AND METHODS Eighteen patients are assessable on this phase I study. The mean age was 54 years (range, 48 to 74). The median number of prior chemotherapy regimens was three (range, two to five). The mean paclitaxel-free interval was 10.1 months (range, 1 to 24). RESULTS A total of 194 cycles of therapy were administered, with a mean of 10 (range, one to 12) per patient. No mucositis or grade III neuropathy was seen. Alopecia occurred in one out of 18 assessable patients. The mean neutrophil nadir was 4.0 x 10(9)/L. At the top dose level (100 mg/m2) delivered, dose-intensity was 90.75% of that planned and greater than two fold the standard dose-intensity. Partial responses were seen in four of 13 assessable patients (30%). Two patients with progression of disease on standard three-week paclitaxel schedules switched to a weekly schedule with demonstrated response. Increasing paclitaxel dose correlated with measured area under the curve (AUC) (R2 = .614). Dose-limiting toxicity was reached at 100 mg/m2 with two of three patients experiencing a treatment delay, thus defining a maximum-tolerated dose of 80 mg/m2 in this group of heavily pretreated patients on this weekly schedule. CONCLUSION (1) Paclitaxel administered as a 1-hour infusion is well tolerated; (2) this schedule of administration does not result in cumulative myelosuppression; and (3) this schedule of administration results in dose-intensive paclitaxel delivery with a favorable toxicity profile.
