PURPOSE The goal of this investigation was to determine if comparing sites of neuroblastoma at relapse after myeloablative chemoradiotherapy and purged autologous bone marrow transplantation (ABMT) with sites of disease at diagnosis and before ABMT could provide insight to the reasons for treatment failure. PATIENTS AND METHODS Ninety-nine patients with high-risk neuroblastoma underwent ABMT after induction chemotherapy, surgery +/- local radiation (RT) and then myeloablative therapy with teniposide (or etoposide), melphalan, doxorubicin, cisplatin, and total-body irradiation (TBI). RESULTS Forty-one of 84 assessable patients (15 toxic deaths) developed progressive disease 1 to 44 months after ABMT. The overall probability of relapse 36 months after ABMT was 49%. Tumor recurred in primary (n = 22), bone (n = 20), bone marrow (n = 18), lung (n = 3), and other sites (n = 9). Eight patients relapsed in the primary site alone, 14 in primary and distant sites, and 19 in distant sites only. Of 41 patients with progressive disease, 33 have died, with a median interval from relapse to death of 4 months. Both bone and bone marrow involvement at diagnosis correlated with specific relapse in that site (P < .05). Bone marrow tumor content at harvest greater than 0.1% also correlated with bone marrow relapse (P = .001). There was an association between incomplete resection of the primary tumor at diagnosis and relapse in that site (P = .06). CONCLUSION Neuroblastoma normally recurs in multiple sites after ABMT, particularly in areas of previous disease. More intensive treatment to known areas of disease (aggressive early surgery, effective myeloablative consolidation therapy) and post-ABMT therapy for minimal residual disease should be studied for their potential to decrease the frequency of relapse.

PURPOSE We analyzed the outcome of autologous bone marrow transplantation (ABMT) in pediatric and adult patients with Hodgkin's disease (HD) by means of a case-controlled study. PATIENTS AND METHODS Eighty-one pediatric HD patients who had undergone ABMT and who had been reported to the European Bone Marrow Transplant Group (EBMTG) Lymphoma Registry were compared with a case-matched group of 81 adult patients who had undergone the same procedure. The case-matching was performed following selection of the main prognostic factors for progression-free survival (PFS) by multivariate analysis. RESULTS The PFS rate was not significantly different between the groups (39% for the pediatric group v 48% for the adult group). The overall relapse/progression rates for the groups were 52% and 40%, respectively. This was not a statistically significant difference and the sites of relapse were similar. There was no significant difference in the incidence or causes of procedure-related morbidity or mortality of the two groups. CONCLUSION This study suggests that patients with pediatric HD have the same outcome at ABMT as their adult counterparts; however, long-term complications will need to be carefully monitored.

PURPOSE This prospective study of patients treated at the Royal Marsden Hospital Lymphoma Unit was designed to evaluate the role of magnetic resonance imaging (MRI) in the assessment of residual masses evident on computed tomographic (CT) scanning following treatment of lymphoma. PATIENTS AND METHODS All patients had MRI, gallium-67 single-photon emission CT (67Ga SPECT), and erythrocyte sedimentation rate (ESR) performed within 3 months of completing therapy. Patients were monitored for 1 year posttreatment and observed for signs of relapse. Investigation results were correlated with disease status, and the sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) calculated. Time-to-relapse curves were derived and the log-rank test used to determine whether patients with a positive result were more likely to have a relapse within the mass than those with a negative result. RESULTS Thirty-four patients were studied, 14 of whom relapsed, 11 within the area of residual mass. Overall, MRI had a high specificity (90%), PPV (71%), and NPV (75%), but poor sensitivity (45%). The results for 67Ga SPECT were similar, apart from lower sensitivity (33%). ESR had inferior performance in predicting relapse compared with the other tests. MRI was the only investigation to show statistical significance (P = .14) in predicting relapse, and this was particularly evident in Hodgkin's lymphoma (P = .003). Combining results of 67Ga SPECT and MRI did not improve predictive power. CONCLUSION These data demonstrate that MRI is a valuable tool in the setting of a residual mass after treatment, giving clinically useful prognostic information. 67Ga SPECT also has a role, but is less effective in predicting relapse than MRI.

PURPOSE Studies of tape recordings of cancer consultations have produced conflicting results. At the same time, audiotapes containing general information about cancer are poorly evaluated and are distributed to patients in an ad hoc manner. We compared the effects of both interventions on patient satisfaction, psychologic adjustment, and recall of information following their first consultation with a medical oncologist. PATIENTS AND METHODS Patients (n = 142) were randomized to receive (1) an audiotape of their consultation, (2) an audiotape describing cancer in general terms, or (3) no tape. Recall of information was assessed in a structured interview 4 to 20 days after the consultation. RESULTS Satisfaction with the consultation increased linearly from no tape to general tape to consultation tape. Satisfaction with the tape itself was higher in patients who received the consultation tape (satisfaction score, 61%) compared with those who received the general tape (43%). Average recall for all groups was 6.4 of the 25 items of information presented, and 2.4 of the six points identified as particularly important by the oncologist. The consultation tape did not improve recall over the no tape control, but the general tape caused a decrease of almost two items in total recall. Spontaneous (ie, unprompted) recall was significantly poorer with the general information tape. Psychologic adjustment to cancer was unaffected. CONCLUSION We conclude that individual audiotapes have a limited potential to increase recall of information from the oncology consultation. General information tapes about cancer appear to inhibit recall actively.

PURPOSE Endoscopic ultrasonography (EUS) has been shown to determine accurately the depth of invasion of the stomach wall in gastric carcinoma. We undertook this study to determine if T (tumor) stage as determined by EUS correlated with recurrence after resection and could be used to identify patients preoperatively at high risk for recurrence. MATERIALS AND METHODS We reviewed the surgical pathology and obtained follow-up data from the first 50 patients who underwent preoperative EUS for staging of gastric carcinoma. Rotating sector-scan ultrasound endoscopes were used with switchable frequencies of 7.5 MHz and 12 MHz. RESULTS Of 50 patients, 43 underwent resection with curative intent and were available for follow-up. The concordance of EUS T stage with pathologic T stage in these patients was 86%. At a median follow-up duration of 25 months, only two of 13 patients with preoperative EUS stage T1 or T2 disease were found to have recurrence, while 23 of 30 patients with EUS stage T3 or T4 disease had recurrence (P = .0002) and 22 died. CONCLUSION We conclude that patients with a preoperative EUS stage T1 or T2 are at low risk for postoperative recurrence, while patients with EUS stage T3 or T4 are at high risk for early postoperative recurrence. The latter patients are reasonable candidates for controlled trials of alternative preoperative management programs, such as chemotherapy, in an effort to improve their poor prognosis.

PURPOSE To provide an investigational drug, paclitaxel, now commercially available, to women with refractory ovarian cancer and to evaluate response and toxicity in these patients. PATIENTS AND METHODS Patients with platinum-refractory ovarian cancer, Eastern Cooperative Oncology Group (ECOG) performance status 0 to 3, at least three prior chemotherapy regimens, adequate hepatic and renal function, and no significant cardiac history were eligible. Patients were treated with paclitaxel 135 mg/m2 administered by 24-hour continuous intravenous infusion every 3 weeks. RESULTS Leukopenia was the most frequent toxicity, with 78% of patients experiencing grade 3 or 4 toxicity. Other grade 3 and 4 toxicities were less common: fever (33%), infection (12%), thrombocytopenia (8%), vomiting (7%), cardiac (2%), neurologic (2%), and mucositis (1%). Fifteen treatment-related deaths (1.5%) were reported. The objective response rate was 22% (4% complete response [CR], 18% partial response; 95% confidence interval [CI] for overall response, 19% to 25%). The median time to progression from treatment initiation was 7.1 months in responding patients and 4.5 months for all patients. The median survival duration was 8.8 months. CONCLUSION Paclitaxel has shown activity in women with platinum-refractory ovarian cancer, and it can be administered with an acceptable safety profile. Further research is needed to determine the optimal role of paclitaxel in the primary and salvage treatment of ovarian cancer.

PURPOSE To establish the optimum biologic dose and maximal-tolerated dose (MTD) of once-daily, subcutaneous recombinant human granulocyte-macrophage colony-stimulating factor derived from yeast (RhuGM-CSF) in patients with breast cancer. PATIENTS AND METHODS Seventeen patients with either newly diagnosed breast cancer with more than four involved axillary nodes (five patients) or metastatic breast cancer (12 patients) were treated with cyclophosphamide 1 g/m2, doxorubicin 50 mg/m2, and fluorouracil 500 mg/m2 (CAF) intravenously (IV) once every 3 weeks. RhuGM-CSF was administered subcutaneously once daily for 14 days after the second and third CAF cycles, at one of three dose levels. RESULTS The 125-micrograms/m2/d RhuGM-CSF dose level shortened the duration of neutropenia in only one of three patients. The 250-micrograms/m2/d level was effective in shortening the duration of the neutropenic nadir (< .5 x 10(9)/dL) by 2 or more days in five of six patients. The 500-micrograms/m2/d level caused severe toxicity (chest pain, two patients; deep vein thrombosis, one patient) in three of eight patients. CONCLUSION RhuGM-CSF administered once daily at the 250-micrograms/m2/d level is well tolerated and effective in shortening the duration of the neutrophil nadir by 2 or more days after CAF therapy.

PURPOSE To determine the bioavailability of oral etoposide capsules administered at doses of 100 mg and 400 mg. PATIENTS AND METHODS The bioavailability of oral etoposide was determined by measuring the area under the etoposide plasma concentration versus time curve (AUC) following intravenous (IV) etoposide administration and comparing that value to the AUC achieved following an oral dose administered 1 day later to the same patient. The bioavailability of a 100-mg oral dose of etoposide was measured on 16 occasions in 11 patients. The bioavailability of a 400-mg dose was determined on 12 occasions in six patients. RESULTS The mean (+/- SD) bioavailability following a 100-mg dose of oral etoposide was 76% +/- 22%, which was significantly greater (P < .01) than the mean bioavailability of 48% +/- 18% following a 400-mg oral dose. The coefficient of variation in oral etoposide bioavailability was significant: 29% with a 100-mg oral dose and 37% with a 400-mg dose. CONCLUSION Bioavailability of a 100-mg oral etoposide dose is greater than suggested in the package insert from Bristol Laboratories (Evansville, IN). Comparable oral etoposide doses are not uniformly twice that of an IV dose, as suggested by the package insert, but will depend on the final oral dose administered. Bioavailability is better at lower oral etoposide doses. This study confirms the wide interpatient and intrapatient variability in oral etoposide bioavailability.

PURPOSE This study was undertaken to evaluate the efficacy of secondary surgical cytoreduction in the management of ovarian cancer. PATIENTS AND METHODS The cases of 100 patients with recurrent or progressive epithelial ovarian cancer whose initial treatment had been cytoreduction followed by cytotoxic therapy with a cisplatin-based regimen were reviewed. All 100 patients underwent surgery, after recurrence or progression was documented preoperatively, by gynecologic oncologists at the Mount Sinai Medical Center, New York, NY, between 1980 and 1991 with the intention of performing radical tumor reduction. RESULTS Sixty-one patients had a secondary cytoreduction that left residual disease less than 2 cm in diameter. The median survival, determined from the date of the secondary cytoreduction to the date of death or last follow-up, is 27.1 months in the optimally treated group and 9.0 months for the 39 patients whose surgery was suboptimal (P = .0001). Other variables associated with statistically significant longer survival, and a significantly higher probability of achieving a successful secondary cytoreduction, included age < or = 55 years at the time of secondary cytoreduction, interval from initial diagnosis to secondary cytoreduction of more than 12 months, residual disease at initial staging laparotomy of less than 2 cm, and a complete clinical response to a cisplatin-based front-line regimen. Multivariate analysis confirms the survival benefit provided by a successful secondary cytoreduction when adjusted for the above variables. There was one postoperative mortality. Ten percent of the successfully cytoreduced patients and 18% of the unsuccessfully cytoreduced patients experienced some degree of postoperative morbidity. CONCLUSION These data justify the performance of secondary cytoreductive surgery for patients who develop gross recurrent or progressive ovarian cancer following cisplatin therapy.

PURPOSE An open, randomized study was performed to assess the effects of supportive pamidronate treatment on morbidity from bone metastases in breast cancer patients. PATIENTS AND METHODS Eighty-one pamidronate patients and 80 control patients were monitored for a median of 18 and 21 months, respectively, for events of skeletal morbidity and the radiologic course of metastatic bone disease. The oral pamidronate dose was 600 mg/d (high dose [HD]) during the earliest study years, then changed to 300 mg/d (low dose [LD]) because of gastrointestinal toxicity. Twenty-nine of 81 pamidronate (HD/LD) patients first received 600 mg/d and were then changed to 300 mg/d; 52 of 81 pamidronate LD patients received 300 mg/d throughout the study. Tumor treatment was unrestricted. RESULTS An overall intent-to-treat analysis was performed. In the pamidronate group, the occurrence of hypercalcemia, severe bone pain, and symptomatic impending fractures decreased by 65%, 30%, and 50%, respectively; event-rates of systemic treatment and radiotherapy decreased by 35% (P < or = .02). The event-free period (EFP), radiologic course of disease, and survival did not improve. Subgroup analyses suggested a dose-dependent treatment effect. Compared with their controls, in pamidronate HD/LD patients, events occurred 60% to 90% less frequently (P < or = .03) and the EFP was prolonged (P = .002). In pamidronate LD patients, event-rates decreased by 15% to 45% (P < or = .04). Gastrointestinal toxicity of pamidronate caused a 23% drop-out rate, but other cancer-associated factors seemed to contribute to this toxicity. CONCLUSION Pamidronate treatment of breast cancer patients efficaciously reduced skeletal morbidity. The effect appeared to be dose-dependent. Further research on dose and mode of treatment is mandatory.

Published: February 2017

PURPOSE This study attempted to determine the outcome of pregnancies in patients (or their partners) who were successfully treated for Hodgkin's disease and to assess the effect of treatment on the children of the treated parents. MATERIALS AND METHODS A questionnaire was distributed to and personal interviews were conducted with patients who were of reproductive age at the time of treatment with consecutive protocols of radiotherapy, chemotherapy, or both. Those premenopausal patients (or the sexual partners of patients) who attempted to conceive after successful treatment constituted the study population. Fertility assessment was based only on those patients identified as desiring children. RESULTS Among 391 adult patients, 221 patients (104 females and 117 males) of reproductive age were interviewed. Before treatment, 63 of the 221 patients had 135 pregnancies, which resulted in 118 children, 11 spontaneous abortions, five elective abortions, and one stillborn. After treatment, 94 patients (43 females and 51 males) actively attempted conception; 35 females and 25 partners of male patients had 84 pregnancies, which resulted in 68 living children. Among the 84 pregnancies, there were one premature birth at 29 weeks, three spontaneous abortions, 11 elective abortions, and two stillborn: one at 32 weeks and one set of twins. The children have been observed for a median of 11 years (minimum follow up > 4.5 years). Of those patients who desired children, 35 of 43 females became pregnant, whereas only 25 of the 51 partners of male patients became pregnant. At least five male patients with low sperm counts apparently fathered children. CONCLUSIONS This study demonstrates that both men and women have the potential for fertility after treatment regardless of treatment modality. The partners of male patients who were treated with combined modality treatment had a lower frequency of pregnancy than did the female patients who attempted conception and their frequency of pregnancy was also lower than the general population. There was no apparent increase in complications of pregnancy, spontaneous abortions, or congenital abnormalities after treatment compared with pregnancies in this patient group before treatment or with pregnancies in the general population.

PURPOSE This study (Childrens Cancer Group [CCG]-105) was designed in part to determine in a prospective randomized trial whether intrathecal methotrexate (IT MTX) administered during induction, consolidation, and maintenance could provide protection from CNS relapse equivalent to that provided by cranial radiation (CXRT) in children with acute lymphoblastic leukemia (ALL) and intermediate-risk features. PATIENTS AND METHODS We randomized 1,388 children with intermediate-risk ALL to the two CNS regimens. They received either IT MTX at intervals throughout their course of therapy or CXRT (18 Gy) during consolidation with IT MTX during induction, consolidation, and delayed intensification. Systemic therapy was randomized to one of four treatment regimens derived from a regimen used by CCG in recent studies for this patient population and three more intensive regimens based on the Berlin-Frankfurt-Munster trials. RESULTS Life-table estimates at 7 years show a 93% and 91% CNS relapse-free survival rate for the CXRT and IT MTX groups, respectively. The corresponding event-free survival (EFS) rates are 68% and 64%. The differences are not significant. Patients who received more intensive systemic therapy had a 94% CNS relapse-free survival rate on either CXRT or IT MTX, while patients who received standard systemic therapy had 90% and 80% rates for CXRT and IT MTX, respectively (P < .0001). Patients less than 10 years of age who received CXRT or IT MTX had 72% and 71% EFS rates if they received more intensive systemic therapy. Patients 10 years or older who received CXRT had an improved EFS (61% v 53%) with a more intensive systemic program. This was primarily due to fewer bone marrow relapses (P = .04). CONCLUSIONS IT MTX during induction, consolidation, and maintenance provides protection from CNS relapse in patients with intermediate-risk ALL equivalent to that provided by CXRT if more intensive systemic therapy is given. The CNS relapse rate with either CXRT or IT MTX is in part dependent on the associated systemic therapy. For intermediate-risk patients less than 10 years of age, IT MTX with an intensified systemic regimen provided CNS prophylaxis comparable to that provided by CXRT, whereas older patients had fewer systemic relapses if they received CXRT.
