Published: February 2017

In a study of 411 patients with small-cell lung cancer (SCLC) entered on therapeutic clinical trials between 1973 and 1987, we analyzed whether changes in the prognostic importance of pretreatment factors had occurred during the 14-year time period. After adjusting for other prognostic factors, brain involvement was associated with shorter survival in patients treated before December 1979 (P = .024) but not in patients treated thereafter (P = .54). The patients diagnosed before 1979 had brain metastases documented by radionuclide scan while computed cranial tomography (CCT) was more commonly used after 1979. Patients who had brain metastases diagnosed by radionuclide scan lived a shorter period of time than patients who had the diagnosis made by the more sensitive CCT scan (P = .031). In contrast, Cox proportional hazards modeling showed that liver metastases in patients were associated with shorter survival in patients treated after 1979 (P = .0007) but not in patients treated before then (P = .30). A larger proportion of patients had a routine liver biopsy before 1979 than after 1979 when more patients had the liver staged with less sensitive imaging studies and biochemical parameters. Patients with SCLC whose cancer was confined to the thorax but had medical or anatomic contraindications to intensive chest radiotherapy had similar survival compared with patients with limited-stage SCLC who were treated with combination chemotherapy alone (P = .68). From these data we conclude: (1) the sensitivity of the staging procedures used can affect the impact on survival of cancer involvement of a given site; and (2) patients with cancer confined to their chest with medical or anatomic contraindications to chest radiotherapy do not have a shorter survival than patients with limited-stage disease treated with chemotherapy alone.

Interferon-gamma (IFN gamma), as produced by recombinant DNA technology, has shown a wide range of immunomodulatory activity in vitro and in vivo. Clinical studies have attempted to establish a dose-response relationship to define optimal dosage ranges for induction of effector cell function and host response in patients with cancer. We conducted a randomized trial to test the in vivo biologic activity of five daily dosages ranging from 3 to 3,000 micrograms/m2, administered by daily 2-hour bolus injection or by continuous infusion for 14 days. We demonstrate comparable immunobiologic effects of recombinant IFN gamma (rIFN gamma; Biogen, Inc, Cambridge, MA) administered by these two schedules at the various dosages tested, and have defined a relationship of dose to biologic response over this 3-log10 dose range. Oligo 2'5' adenylate synthetase (2'5'As) induction, natural-killer (NK) cell activity, and T-cell subset distribution (heightened T helper/suppressor ratio) showed the most consistent treatment-associated changes and the greatest immunobiologic effects at dosages of 300 to 1,000 micrograms/m2. Mononuclear cell DR and DQ antigen expression showed no consistent dose-related treatment effect. The relevance of the phenotypic, functional, and enzymologic effects observed in this trial to any clinical antitumor effects of IFN gamma in cancer therapy must now be established.
Stage I-II pediatric Hodgkin's disease: long-term follow-up demonstrates equivalent survival rates following different management schemes.

Published: February 2017

The results of treatment of 171 children with stage I-II Hodgkin's disease from two institutions with differing approaches to management have been analyzed. At the Stanford University Medical Center/Children's Hospital at Stanford (SUMC/CHaS), pathologic staging followed by extended-field radiation alone or involved-field radiation plus combination chemotherapy have been cardinal to the management policy. At St Bartholomew's Hospital/The Hospital for Sick Children at Great Ormond Street (Barts/GOS), clinical staging only has been used over the last 10 years, and involved/regional-field radiotherapy used as the treatment of choice rather than extended-field radiotherapy. Some children at each institution received combined modality therapy as primary management. Relapse among children with stage I disease was a more frequent occurrence in the Barts/GOS series than in the SUMC/CHaS group. However, the survival rates from the two centers are identical, 91% at 10 years. The following scientific-philosophic question is asked: Should one maximally stage and treat all children to increase the likelihood of a high freedom from relapse (FFR; cure) rate, or is it acceptable to minimize the initial staging and treatment, realizing that a proportion of patients will fail and require salvage/rescue therapy? With the awareness of morbidity from pathologic staging and aggressive treatment, and the favorable survival data reported from specialized centers using differing approaches, treatment strategies should be directed toward the long-term goal of cure of disease with maximal quality of life. A multidisciplinary management philosophy undertaken at a center with extensive experience in pediatric Hodgkin's disease is important to achieving this goal.

Published: February 2017

Sixty-eight unselected patients with progressive metastatic renal cell carcinoma (RCC) were treated between March 1985 and November 1988 with continuous infusion floxuridine (FUDR). Thirty-seven percent of these patients had previously received and failed systemic treatment. Using implantable pumps for automatic drug delivery, FUDR was continuously infused for 14 days at monthly intervals. The starting dose was 0.15 mg/kg/d (intravenous [IV]; n = 61) or 0.25 mg/kg/d (intraarterial [IA]; n = 7); IV doses were increased or decreased in increments of 0.025 mg/kg/d as permitted by toxicity. Diarrhea (with or without mild abdominal cramping) and nausea/vomiting limited the FUDR IV infusion, and hepatic function abnormalities limited FUDR IA infusion. The use of a circadian-modified infusion schedule permitted high FUDR doses to be safely given as compared with a constant rate infusion schedule. Of 63 patients assessable for response, 56 received systemic FUDR infusion. Four complete responses (CRs; 7.1%); and seven partial responses (PRs; 12.5%) were observed (objective response rate, CR plus PR, 19.6 +/- 5.1% [95% confidence limits] ). The median objective response duration was 10.8 months (range, 1 to 18 months; mean, 9.4 +/- 1.6). Four additional patients had minor tumor responses (MRs; 7.1%). In a subgroup of seven assessable patients receiving hepatic arterial FUDR, we observed one CR and three PRs (57.2 +/- 42.8%). Overall, objective response (CR plus PR) was seen in a quarter of assessable patients treated, 15 of 63, while only 15 of the 63 assessable patients (25.4%) have had objective tumor progression. The median follow-up time for all 68 patients was 28 months (range, 1 to 42), and their median survival duration is 15 months (range, 3 to 37 months). Continuous infusion FUDR is an effective outpatient treatment for progressive metastatic RCC, producing durable tumor response and causing little toxicity.

Ondansetron, a 5HT3 antagonist, was given to 20 children aged 4 to 18 years who were undergoing treatment with the Australian and New Zealand Childhood Cancer Study Group Acute Lymphocytic Leukaemia (ALL) Study V Protocol. The study was open, dose ranging, and noncomparative, and designed to evaluate safety and efficacy of ondansetron in preventing nausea and vomiting caused by cyclophosphamide intravenous (IV) 1,000 mg/m2 day 1, and cytarabine IV subcutaneously (SC) 75 mg/m2 on days 2 to 5. Ten patients were given ondansetron 5 mg/m2 IV (group A) and subsequently another 10 patients were given ondansetron 3 mg/m2 IV (group B). Oral ondansetron was given for 14 doses, at the same dosage for both groups, commencing simultaneously with the IV infusion and continuing at 8 hourly intervals, ie, until day 5. The oral dose was based on surface area with the following schedule: 0.3 to 0.6 m2, 2 mg; 0.6 to 1 m2, 3 mg; and greater than 1 m2, 4 mg. Vomiting on the first day of chemotherapy was reported in group A by one patient and by one patient in group B. Vomiting during days 2 to 5 was reported by two group-A patients and by three group-B patients. Nausea was recorded on day 1 by one patient in group A, and two in group B, and on days 2 to 5 by three patients in group A, and by seven in group B. All patients were alert during treatment with ondansetron and there was no dystonia. There were no changes in renal function or hematology values that could be ascribed to the study drug. Transient elevations in bilirubin and liver enzymes were observed. We conclude that our results indicate that ondansetron is a safe and extremely effective single-agent antiemetic with minimal side effects, when administered both IV and orally.

Published: February 2017

In an attempt to evaluate the radiocurability of microscopic disease in childhood rhabdomyosarcoma (RMS) with total tumor doses of less than 4,000 cGy, we performed a retrospective analysis of all patients with microscopic residual RMS who were treated at the Memorial Sloan-Kettering Cancer Center (MSKCC) during the years 1970 to 1987. There were 32 patients ranging in age from 3 months to 22 years (median, 6 years) with microscopic residual of either (1) a localized primary tumor (MSKCC, stage IB; Intergroup Rhabdomyosarcoma Study [IRS] group IIA), 19 patients; or (2) an involved lymph node region with the primary tumor completely resected (MSKCC stage III; IRS group IIC), 13 patients. Twenty-nine of the 32 patients presented with embryonal histology. All patients were treated with combination chemotherapy (CT) and megavoltage external beam radiotherapy (RT). The RT was delivered in either conventional fractionation of 180 to 200 cGy daily (30 patients) or hyperfractionation of 150 cGy twice daily (two patients). Fifteen patients received RT doses of less than 4,000 cGy with a range of 3,000 to 3,600 cGy and a median value of 3,100 cGy; 17 patients received 4,000 cGy or more with a range of 4,000 to 6,000 cGy and a median value of 4,600 cGy. With a median follow-up of 11 years, the relapse-free survival was 25 of 32 patients (less than 4,000 cGy, 12 of 15; greater than or equal to 4,000 cGy, 13 of 17). The RT local control rate was 30 of 32 (less than 4,000 cGy, 14 of 15; greater than or equal to 4,000 cGy, 16 of 17 [P = .94]). Our results suggest that radiation doses of below 4,000 cGy, when combined with effective multiagent CT, may be sufficient for local control of microscopic disease in childhood embryonal RMS.

Published: February 2017

We conducted a pilot protocol at seven Pediatric Oncology Group (POG) institutions to examine the feasibility, toxicity, and efficacy of using a common regimen of high-dose chemoradiotherapy (HD CT/RT) supported by autologous or allogeneic marrow infusions in children with metastatic neuroblastoma (NBL) in first or second remission. During a 57-month period, we accrued 101 patients. We report here results for the 81 who completed treatment at least 2 years ago. The HD CT/RT regimen consisted of melphalan 60 mg/m2/d for three doses, and total body irradiation (TBI) either 1.5 Gy (n = 27) or 2.0 Gy (n = 54) twice daily for six doses. Twenty-three patients also received irradiation consisting of 1.2 Gy twice daily for 10 doses to persisting disease sites. Seventy-four were given autologous and seven allogeneic marrow, 64 autologous marrows being purged immunomagnetically. Fifty-four children were in first complete (CR) or partial (PR) remission and 27 in second CR or PR. As of October 1, 1990, follow-up was from 32 to 72 months. Forty-seven of these 81 children relapsed, 10 died of complications, one of unknown cause, and 23 continue in remission, including 21 of the 54 treated in first remission, and 16 who completed treatment more than 3 years ago. The 2-year actuarial event-free survival (EFS) probabilities are first CR (CR1) 32% (SE 10%), first PR (PR1) 43% (SE 9%), second CR (CR2) 33% (SE 27%), and second PR (PR2) 5% (SE 5%). Probability of EFS correlated with remission number (first better than second, P less than .001), with interval from diagnosis to HD CT/RT (greater than 9 months better than less than 9 months, P = .055), and with TBI dose (12 Gy better than 9 Gy, P = .031). These encouraging results may partly reflect selection for this treatment of patients with NBL who have a slower disease pace.

Carboplatin (CBDCA) is a second-generation platinum drug that has been shown to be useful when used as a continuous infusion in treatment of refractory adult leukemia. We report on the effectiveness of continuous infusion CBDCA, 300 mg/m2/d x 5 days, as evaluated in nine patients with secondary acute nonlymphocytic leukemia (ANLL) (seven previous myelodysplastic syndrome and two treatment-associated ANLL), three ANLL patients in first relapse, six refractory ANLL, and nine patients with blastic phase of chronic myelogenous leukemia (BP-CML). All patients were considered assessable. The response rate was 44% (eight complete remissions [CRs], four partial remissions [PRs]). Median duration of postchemotherapy neutropenia was 36 days (range, 18 to 45). Therapy was well tolerated, and toxicity was mainly hematologic and nondose-limiting. Despite prolonged neutropenia, severe infections were rarely seen, and most patients were managed as outpatients. Twelve patients had nausea and vomiting, two had symptomatic hypomagnesemia, and one patient showed reversible ototoxicity. Because of substantial antileukemic activity and unusual extrahematologic toxicity, CBDCA appears to be an effective second-line agent in the treatment of ANLL and should be considered for upgrading to first-line treatment regimens.

Phase II trials of second-line intraperitoneal (IP) cisplatin-based therapy in patients with ovarian cancer have demonstrated the ability of this approach to produce objective antitumor responses, including surgically defined complete responses (CRs), in individuals with persistent small-volume disease after front-line cisplatin-based intravenous (IV) treatment. To examine the influence of a prior response to systemic cisplatin on the activity of second-line IP cisplatin, we retrospectively analyzed two phase II trials of cisplatin-based IP therapy in persistent/recurrent ovarian cancer conducted at our institution. Of the 89 assessable patients on the two trials, 52 (58%) had previously responded to IV cisplatin. The overall response and CR rates to second-line IP cisplatin-based therapy in this previously responding population were 56% and 33%, respectively, compared with overall response and CR rates in the 37 nonresponders to IV cisplatin of 11% and 3%, respectively (P less than .001; chi 2, 1 df). In the 36 patients responding to systemic cisplatin and whose largest tumor mass measured less than 1 cm at IP cisplatin initiation, a 42% CR rate was observed, compared with a 7% CR rate in the 14 patients with the same bulk of disease who had previously failed to respond to systemic cisplatin (P less than .025). We conclude that a prior response to systemic cisplatin strongly influences the antineoplastic activity of second-line IP cisplatin in ovarian cancer.

We describe a phase I-II study of two consecutive 5-day courses of a three-drug regimen of ifosfamide (IFM), carboplatin (CBDCA), and either etoposide (VP-16) (regimen 1) or teniposide (VM-26) (regimen 2) in high doses together with autologous bone marrow transplantation (ABMT), for previously treated patients with ovarian carcinoma (OC), germ cell tumors (GCT), gestational trophoblastic disease (GTD), or oat cell carcinoma (OCC). Forty-four patients entered the study. Two patients with OC received regimen 1, and 22 were given regimen 2. Sixteen patients with GCT, two with GTD, and two with OCC were treated with regimen 1. Six patients (13%) died of toxicity. Nephropathy and esophagitis were the dose-limiting toxic effects. The maximum-tolerated doses (MTDs) were 1,500 and 200 mg/m2/d for 5 days for IFM and CBDCA, respectively, in combination with VP-16 250 mg/m2/d for 5 days (regimen 1), and 150, 1,500, and 200 mg/m2/d for 5 days for VM-26, IFM, and CBDCA, respectively (regimen 2). The response rate of patients with OC was 78% (complete response [CR], 14%). For patients previously resistant to chemotherapy, the response rate was 70%. There were no long-term disease-free survivors among patients with OC. The response rate of patients with GCT was 60% (CR, 33%). All responders with GCT were resistant to previous chemotherapy. Unmaintained CRs lasted 2, 6, 8+, 27+, and 37+ months. Of the two patients with GTD, one with previous resistance to chemotherapy attained a CR of 18+ months. One patient with OCC attained a CR lasting 6 months. The regimen possesses great antitumor activity. It produced CRs of long duration in a number of patients with GCT and GTD who were previously resistant to chemotherapy.

Published: February 2017

Cisplatin is one of the most active chemotherapeutic agents for the treatment of squamous carcinoma of the head and neck; however, neurotoxicity and nephrotoxicity are dose-limiting. The analog, carboplatin, is a promising new agent with similar activity but a different spectrum of toxicity. To evaluate if a therapeutic advantage could be achieved with acceptable toxicity, a combination of carboplatin 350 mg/m2 and cisplatin 50 mg/m2 were administered every 28 days to patients with recurrent or metastatic disease who had received no prior chemotherapy. Of 24 patients enrolled in this study, 21 were assessable for response and toxicity. Five partial responses were observed (24%; 95% confidence interval [Cl], 4.9% to 38.6%). No complete response occurred. Two of these patients received definitive radiotherapy and achieved complete responses. The median survival of all patients was 24 weeks. Hematologic toxicity was dose-limiting necessitating a decrease in the starting dose of carboplatin to 300 mg/m2. Nonhematologic toxicity was infrequent and mild. Significant renal impairment occurred in only two patients. Although treatment with the combination of carboplatin and cisplatin is feasible, we found no therapeutic advantage in terms of an increased response or survival.

Thirty patients with chemotherapy-induced anemia were treated with recombinant human erythropoietin for 4 weeks. In this dose-escalation study, cohorts of five to eight patients were treated per dose level. The doses of erythropoietin were 25, 50, 100, 200, or 300 IU/kg/d given intravenously for 5 days each week. Of 30 patients, 15 (50%) had a greater than 10% increase of their hemoglobin (Hb) values and were considered responders. At the two highest dose levels, 11 of 13 patients (85%) responded. In the 15 responding patients, the mean Hb level increased by 1.7 g/dL from baseline compared with an average decrease of 1.5 g/dL in the previous cycles of chemotherapy without erythropoietin administration. Recombinant human erythropoietin is effective in ameliorating chemotherapy-induced anemia when administered in adequate doses.

The biologic in vivo effects of recombinant human interleukin-3 (rhIL-3) were assessed in a phase I clinical study of 30 patients with advanced malignancy. On day 1 rhIL-3 was administered by a single intravenous (IV) bolus injection, followed by subcutaneous (SC) injections once daily from day 2 to 15; at least three patients were treated at each dose level (60, 125, 250, and 500 micrograms/m2). A transient decrease of eosinophil and monocyte counts was observed immediately after IV injection of rhIL-3, whereas the neutrophil count remained unaffected. Total WBC counts and neutrophil counts increased dose dependently up to threefold, whereas a 10-fold to 50-fold rise was observed in levels of circulating eosinophils and basophils. Platelet counts increased up to twofold. Patients developed moderate increases of serum levels of soluble interleukin-2 receptors, beta 2-microglobin, and immunoglobulin M (IgM), and of the acute phase reactants, C-reactive protein (CRP), fibrinogen, and haptoglobin. An increase in interleukin-6 (IL-6) serum levels was detected in patients treated by IV bolus rhIL-3. The serum half-life of IV injected rhIL-3 was 20 +/- 3 minutes; after SC administration, 210 +/- 15 minutes. Administration of rhIL-3 was generally well tolerated, with mild fever, headache, and local reactions at the injection site being the most frequent side effects. The primary course of the underlying malignant diseases was not significantly altered by administration of rhIL-3. The results indicate that rhIL-3 acts in vivo as a multilineage hematopoietic growth factor and a weak inflammatory mediator that may be used successfully to improve states of hematopoietic failure.
Adjuvant chemotherapy with doxorubicin plus cyclophosphamide, methotrexate, and fluorouracil in the treatment of resectable breast cancer with more than three positive axillary nodes.

Published: February 2017

To improve current adjuvant results in high-risk breast cancer, in February 1982 we activated a prospective randomized trial using both intravenous cyclophosphamide, methotrexate, and fluorouracil (CMF) and Adriamycin (doxorubicin; Farmitalia-Carlo Erba, Milan, Italy) involving patients with resectable mammary carcinoma and more than three positive axillary lymph nodes. The objective of the study was to assess the effectiveness of four courses of Adriamycin followed by eight courses of CMF versus two courses of CMF alternated with one course of Adriamycin for a total of 12 courses. All drug courses were recycled every 3 weeks. Rather than temporarily reducing doses in the event of myelosuppression on the planned day of treatment, drug administration was delayed for 1 to 2 weeks. At a median follow-up of 59 months, treatment outcome was significantly superior for patients who received Adriamycin followed by CMF (Adriamycin----CMF) than for those given alternating regimens (CMF/Adriamycin). The 5-year relapse-free survival was superior post-Adriamycin----CMF (61%) compared with post-CMF/Adriamycin administration (38%; P = .001). The corresponding figures for the 5-year total survival were 78% and 62%, respectively (P = .005). The benefit of Adriamycin----CMF was observed in all patient subsets. Treatment was fairly well tolerated, and we documented only one case of fatal congestive heart failure in a patient who received postoperative irradiation to the left breast in addition to Adriamycin. Present findings indicate that in women with extensive nodal involvement, Adriamycin----CMF yielded superior results compared with CMF/Adriamycin.

Published: February 2017

Myeloablative treatment intensification in 25 patients diagnosed when older than 12 months of age with stage IV neuroblastoma included sequential delivery of cisplatin 120 mg/m2 x 1, hyperfractionated radiation (2,100 cGy) to the primary site and adjacent lymph nodes, carmustine (BCNU) 200 mg/m2 x 1, melphalan 60 mg/m2/d x 3 (n = 13) or thiotepa 300 mg/m2/d x 3. (n = 12), and etoposide (VP 16) 300 mg/m2/d x 3. Seventy-two hours after the last dose of VP 16, histologically tumor-free and 4-hydroperoxycyclophosphamide (4-HC; 100 mumol/L)-purged autologous bone marrow (ABMT) was infused. Acute toxicities included grade 3 to 4 oral mucositis, grade 1 to 2 diarrhea, and fevers. No patient required infusion of unpurged reserve autografts. At ABMT, 16 patients (group I) were progression-free 6.5 months to 14 months (median, 9 months) from diagnosis: seven remain progression-free 20 months to 46 months (median, 39 months) off therapy, six relapsed 4 months to 17 months post-ABMT, and three died of toxicity (candidiasis, metabolic derangement, and venoocclusive disease [VOD]). The event-free survival of group I patients is 44% at 24 months post-ABMT. Nine patients (group II) were in second remission at ABMT, including three who had relapsed after other transplant procedures: two are progression-free 24 months and 41 months off therapy, four relapsed 3 months to 12 months post-ABMT, and three died of toxicity (aspergillosis, hemorrhagic cystitis, VOD). Only one of 10 relapses involved a primary site, suggesting a beneficial effect of local radiation. In terms of survival or toxicity, an advantage for melphalan or thiotepa was not evident. Regimens such as this may prolong the survival of selected patients with poor-risk neuroblastoma, but concerns over late relapses and toxicity mandate continuing efforts to devise alternative, less risky, and more clearly beneficial approaches for definitive ablation of neuroblastoma.
Quality of life in long-term survivors of CNS tumors of childhood and adolescence.

Published: February 2017

Clinical reports of small numbers of pediatric brain tumor patients observed for brief periods suggest that long-term survivors continue to have major handicaps into adulthood. To quantify these late effects we interviewed 342 adults (or their proxies) who had CNS tumors diagnosed before the age of 20 between 1945 and 1974, survived at least 5 years, and reached 21 years of age. Survivors were 32 years old on average at follow-up. When compared with 479 matched siblings as controls. CNS tumor survivors were more likely to have died or to have become mentally incompetent sometime during the follow-up period. They were more likely to be at risk for such adverse outcomes as unemployment (odds ratio [OR], 10.8; 95% confidence interval [CI], 4.6 to 25.7], to have a health condition that affected their ability to work (OR, 5.9; CI, 3.7 to 9.4), to be unable to drive (OR, 28.8; CI, 6.9 to 119.9), or to describe their current health as poor (OR, 7.8; CI, 1.7 to 35.7). Unfavorable outcomes were more frequent in male survivors than in females, in those with supratentorial tumors compared with infratentorial ones, and in those who received radiation therapy. As clinicians consider improving therapies, they should anticipate late effects, such as those we observed, and attempt to target subgroups for interventions that may improve subsequent quality of life.

Children older than 1 year of age who have neuroblastoma with complete or partial removal of the primary tumor and positive intracavitary lymph nodes (Pediatric Oncology Group [POG] stage C) are a small but higher-risk subset of patients. To further evaluate the importance of identifying patients with POG stage C neuroblastoma and to assess the efficacy and toxicity of adding concurrent radiation therapy (RT) to chemotherapy (CT) in these children, a randomized study was conducted. Eligible patients received cyclophosphamide 150 mg/m2 orally days 1 to 7 and Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) 35 mg/m2 intravenously (IV) on day 8 (CYC/ADR) every 3 weeks for five courses with or without RT to primary tumor and regional lymph nodes (24 to 30 Gy/16 to 20 fractions). Second-look surgery was advised to evaluate response and to remove residual disease. Continuation therapy alternated CYC/ADR every 3 weeks with cisplatin 90 mg/m2 day 1 followed by teniposide 100 mg/m2 day 3 (CDP/VM) for two courses each. Secondary CT with CDP/VM alone was available for patients not achieving complete response (CR) following induction treatment and second-look surgery. Of 29 eligible patients randomized to CT alone, 13 achieved CR, and nine are disease-free (NED) 1 to 52 months (median, 35 months) off therapy. Twenty-two of 33 eligible cases treated with CT/RT attained CR, and 19 are NED 1 to 77 months (median, 23 months) off therapy. Local and metastatic relapses occurred in both arms. Differences in CR, event-free survival, and survival rates were significant, P = .013, .009, and .008, respectively. Surgical compliance was excellent and complications uncommon. Therapy was tolerable in both groups but hematopoietic toxicity was more common in the CT/RT arm. We conclude that POG stage C neuroblastoma in children older than 1 year of age is a higher-risk group that should be identified, that CT/RT provides superior initial and long-term disease control compared with CT alone in this patient subset, and that the occurrence of metastatic failures in both treatment groups suggests a need for more aggressive chemotherapy.

Seventy-five patients with advanced epithelial ovarian cancer were treated with a combined modality regimen of systemic, induction chemotherapy followed by intraperitoneal therapy (IPT). All patients underwent initial surgery for staging and/or cytoreduction followed by cisplatin 20 mg/m2 intravenously (IV) for 5 days and cyclophosphamide 600 mg/m2 on day 4 every 3 to 4 weeks for two to four cycles. Patients were then evaluated for IPT and, if eligible, had an intraperitoneal (IP) catheter placed. IPT consisted of cisplatin 60 mg/m2 in 2 L on day 1 and IV cyclophosphamide 600 mg/m2 on day 2 every 3 weeks for three to six cycles. Patients who demonstrated a clinical complete response (CCR) were then referred for second-look laparotomy (SLL). Of 71 patients who completed the induction phase, 53 (75%) were eligible for IPT, and 49 patients entered the therapy phase. Toxicity of the combined modality approach was acceptable and did not differ from our previous experience using the same drugs systemically. Thirty-two of the 49 patients who completed IPT achieved a CCR, which was confirmed by SLL in 20 patients. Twenty recurrences were documented in the 32 CCR patients, 13 occurred in patients after SLL. Projected median survival of all patients is 38 months. Median survival correlated with amount of residual disease following initial surgery (23 months for bulky v 45 months for minimal residual; P less than .001) and with performance status ([PS]; 24 months for PS 2, 3 v greater than 46 months for PS O; P less than .001). Patients who presented with bulky tumors were less likely to reach the consolidation IPT phase. Incorporation of IP cisplatin into the first-line regimen for treatment of ovarian cancer does not appear to have major impact on the survival of all treated patients when compared with our historical control series. Combined IV and IPT cisplatin and cyclophosphamide is feasible with acceptable toxicity. Its impact on response and survival may be limited to only "good-prognosis" patients.

Forty patients with advanced, resectable squamous cell carcinoma of the larynx, oropharynx, or hypopharynx whose surgery would have required total laryngectomy (TL), were treated with one to three cycles of cisplatin-based chemotherapy before local therapy with the goal of larynx preservation. Clinical complete responses (CRs) or partial responses (PRs) to chemotherapy were seen in 26 of 40 patients (65%). Three patients with primary-site disease unresponsive to chemotherapy underwent resection of the primary lesion and neck dissection followed by radiation therapy (RT). Thirty-seven patients were referred after chemotherapy for RT +/- neck dissection. Thirty-one of 40 patient (78%) were rendered disease-free (no evidence of disease [NED]). With a median follow-up of 49 months (range, 31 to 76), the overall actuarial survival rate for the group was 58% at 2 years and 33% at 5 years. The failure-free survival rate was 42% and 33% at 2 and 5 years, respectively. Seven patients refused recommended TL throughout their course. This may have adversely affected survival results. A greater proportion of patients who achieved a CR or PR to chemotherapy remained disease-free compared with those who achieved less than a PR (P less than .001). Sixteen patients relapsed, 10 with locoregional disease. Six patients underwent TL, either for initial induction failure or at relapse, for an actual larynx-preservation rate of 34 of 40 patients (85%). If the seven patients who refused TL are included, the anticipated preservation rate is 27 of 40 patients (68%). Larynx preservation with combined chemotherapy and radiation is feasible and effective in patients with advanced, resectable squamous cell carcinoma of the head and neck (SCHN). This treatment approach requires a motivated patient, careful patient monitoring, and close interdisciplinary cooperation among oncologists.
Cyclophosphamide cardiotoxicity in bone marrow transplantation: a prospective evaluation of new dosing regimens.

Published: February 2017

Cyclophosphamide (CY) cardiotoxicity may be a lethal complication of bone marrow transplantation. Previous echocardiographic studies have reported that left ventricular dysfunction due to CY occurs in over 50% of patients undergoing transplantation. To evaluate the cardiotoxicity of new dosing protocols that included twice-daily rather than once-daily CY, 44 bone marrow transplantation patients were prospectively evaluated with serial ECGs and echocardiograms. Twenty-six patients received a once-daily lower-dose protocol (mean total 87 +/- 11 mg/kg), and 18 patients received a twice-daily higher-dose (mean total 174 +/- 34 mg/kg) CY regimen. In the higher-dose CY group, significant reductions in summed ECG voltage (-20%) (P less than .01) and increases in left ventricular mass index (LVMI) (+10%) (P less than .05) were detected in the first week following therapy. These changes resolved by the third week following CY and were significantly greater than the changes noted in the lower-dose group. However, left ventricular ejection fraction (EF) did not change significantly in either group. Five patients developed clinical cardiotoxicity (four, pericarditis; one, congestive heart failure); four of the five patients were in the higher-dose group (P = .14). Only a prior history of congestive heart failure or a baseline EF less than 50% was an independent correlate of clinical cardiotoxicity (P less than .05). Thus, dose-dependent cardiotoxicity following the use of CY for bone marrow transplantation is evident as reversible decreases in ECG voltage and increases in left ventricular mass, possibly reflecting myocardial edema or hemorrhage. However, systolic dysfunction is much less common with these new twice-daily dosing regimens when compared with earlier studies of high-dose once-daily CY.
Mycosis fungoides and the Sézary syndrome: a review of pathogenesis, diagnosis, and therapy.

Mycosis fungoides (MF) and the Sézary syndrome (SS) are non-Hodgkin's lymphomas with a T-cell phenotype, which have cutaneous involvement as their predominant feature. These disorders are becoming more common, and the patients are frequently being referred to medical oncologists for assistance in management. The development of advanced laboratory techniques, such as molecular genetics and cell-surface phenotyping, has greatly enhanced our understanding of their pathogenesis and may lead to identification of responsible etiologic factors. A myriad of treatment options have been investigated including topical approaches, systemic chemotherapy, and external radiation. Currently, extensive trials are underway examining the potential benefits of agents such as the interferons, interleukin-2, monoclonal antibodies, the retinoids, 2-chlorodeoxyadenosine, and other novel biologic response modifiers or chemotherapeutics. Although all these therapies have benefit in phase II trials, few randomized comparative trials have been performed to identify optimal therapies. Performance of such trials should now become a priority.
Improved results with the addition of interferon alfa-2b to dacarbazine in the treatment of patients with metastatic malignant melanoma.
Authors: Falkson C I , Falkson G , Falkson H C
Published: February 2017

Sixty-four patients with histologically confirmed metastatic malignant melanoma were entered on a prospectively controlled randomized trial. Patients received dacarbazine (DTIC) alone or DTIC plus interferon (IFN) alfa-2b. Patients were reasonably balanced with respect to age, sex, performance status (PS), site of metastases, and number of metastatic sites. Objective response (complete plus partial remission [CR + PR]) was documented in six patients on DTIC and in 16 patients on DTIC plus IFN alfa-2b. Median time to treatment failure (TTF) and median survival are significantly better on the combination arm, with some long-term CRs observed. More toxicity was encountered in the combination arm, which was acceptable except in three patients where treatment was discontinued because of IFN toxicity.

Patients with Hodgkin's disease who were previously untreated with chemotherapy received the chlorambucil, vinblastine, procarbazine, and prednisone (CHLVPP) regimen plus limited involved-field radiation therapy for treatment of Hodgkin's disease through the Nebraska Lymphoma Study Group. One hundred patients, 87 with newly diagnosed Hodgkin's disease and 13 who relapsed after receiving previous radiation therapy, were treated with this regimen between 1982 and 1989. Complete remissions (CRs) were obtained in 88 of 100 patients (88%), and there have been a total of eight relapses. The overall 3-year failure-free survival was 76%, with good-prognosis patients (ie, Karnofsky performance status greater than or equal to 80) having a 3-year failure-free survival of 87%. Toxicity with this regimen was minimal, with neutropenic fevers reported in 13% of the patient population, moderate alopecia in 5%, and mild to moderate nausea and vomiting in 11% of the patients. As primary induction therapy for Hodgkin's disease, CHLVPP is an effective regimen with a high patient acceptance profile.
Ifosfamide, Fanconi's syndrome, and rickets.

Published: February 2017

Three of 218 children treated with ifosfamide plus the uroprotectant mesna, in single- or combination-agent protocols, have developed Fanconi's renal syndrome, all of whom were in a subgroup of 86 children who had also received cisplatin or carboplatin therapy. Patients receiving ifosfamide who have received prior cisplatin (or carboplatin) are at significantly higher risk of developing Fanconi's syndrome than are those who have received no prior nephrotoxic therapy (P = .04). The role of prior nephrotoxic therapy, including cisplatin and its derivatives, and the total dose of ifosfamide should be considered in the assessment of this rare but serious and apparently irreversible side effect.

Clinical and pathologic factors were analyzed in 40 patients with localized muscle-invasive bladder carcinoma treated in a prospective bladder-preserving program consisting of transurethral tumor resection, neoadjuvant chemotherapy (methotrexate, cisplatin, and vinblastine [MCV]), and 4,000 cGy radiotherapy with concurrent cisplatin. Patients with biopsy-proven complete response after chemotherapy and 4,000 cGy radiation received full-dose radiotherapy (6,480 cGy) with cisplatin. Cystectomy was recommended to patients with residual disease. Distant metastasis rate was associated with tumor stage and size: 0% in T2 patients, 39% in T3-4 patients (P = .035), 6% for tumors less than 5 cm, and 59% for tumors greater than or equal to 5 cm (P = .002). Risk of bladder tumor recurrence was higher in patients with tumor-associated carcinoma in situ (CIS; 40%) than those without CIS (6%; P = .075). Papillary tumors and solid tumors both had similar treatment outcomes. By multivariate analysis, tumor stage T2 (P = .04) and absence of CIS (P = .03) were significant predictors of complete response; CIS was predictive of local bladder recurrence (P = .07); and tumor size (P = .03), response after chemoradiotherapy (P = .02), and vascular invasion (P = .08) were associated with distant metastasis. Six of eight local bladder tumor recurrences were superficial tumors. The low actuarial distant metastasis rate of T2 patients (0% at 3 years), the 3-year actuarial overall survival rates for T2 (89%) and T3-4 (50%) patients, and the similar treatment outcomes for papillary versus solid tumors are encouraging when compared with published historical controls. These results provide preliminary evidence (median follow-up, 30 months) that the current chemoradiotherapy regimen may have beneficial effects in the treatment of muscle-invasive bladder carcinoma. The true efficacy of neoadjuvant chemotherapy remains to be proven by ongoing randomized trials.

Thirty-nine patients with untreated acute promyelocytic leukemia (APL) were randomly allocated to receive rubidazone (zorubicin) 200 mg/m2/d, days 1 to 4 plus cytarabine (Ara C) 200 mg/m2/d, days 1 to 7 (arm A, 21 patients), or amsacrine (Amsa) 150 mg/m2/d, days 1 to 4 plus Ara C 200 mg/m2/d, days 1 to 7 (arm B, 18 patients). Prophylaxis of disseminated intravascular coagulation was made by platelet transfusions and heparin. In case of leukemic resistance, patients received a second course with 2 days of rubidazone (arm A) or Amsa (arm B) and 3 days of Ara C. Patients who achieved complete remission (CR) received three consolidation courses with the two drugs used for induction and maintenance therapy for 3 years. Two patients in arm A and one in arm B were allografted in first CR. Initial characteristics were similar in both arms. In arm A, 18 patients (86%) reached CR, two had hypoplastic death, and one had leukemic resistance after two courses. In arm B, 12 patients (66%) achieved CR, two had early death (CNS bleeding, one case; ventricular fibrillation, one case), and four had resistant leukemia after two courses. The difference in CR rate between the two arms was not significant. In arm A, disease-free survival (DFS) showed a plateau at 54.3% after 34 months (95% confidence interval [CI], 32.1% to 74.9%), with eight CRs longer than 34 months. In arm B, DFS was significantly shorter (P less than .03), showing a plateau at 16.7% after 38 months (95% confidence interval, 4.7% to 44.6%), and only two prolonged CRs were seen. The difference in DFS remained significant after censoring allografted patients and patients who died in CR (one in arm A, two in arm B). Our results suggest that Amsa-Ara C combinations may be inferior to anthracycline-Ara C combinations in the treatment of APL, because they seem to provide shorter DFS and, possibly, a higher incidence of initial leukemic resistance. However, studies with larger numbers of patients are required.
