Childhood acute lymphoblastic leukemia with an initial leukocyte count greater than or equal to 100 X 10(9)/L responds poorly to conventional chemotherapy. To extend event-free survival (EFS) in this disease, we devised a protocol that specifies intensive 2-week courses of teniposide (VM-26, 165 mg/m2) plus cytarabine (ara-C, 300 mg/m2), before and immediately after standard 4-week remission induction therapy with prednisone, vincristine, and L-asparaginase. The VM-26 and ara-C combination was also administered intermittently for the first year of continuation treatment with oral 6-mercaptopurine and methotrexate. CNS prophylaxis consisted of periodic intrathecal (IT) injections of methotrexate and delayed cranial irradiation. At a median follow-up of 4 years, the estimated EFS rate for 57 consecutive patients with leukocyte counts of 100 to 1,000 X 10(9)/L was 44%, compared with 10% for matched controls (P less than .001). Remission induction rates in the two groups were similar (82% v 72%, P = .16). Twenty-five patients in the VM-26/ara-C group have survived without adverse events for 2.7 to 6.8 years, whereas only nine of the controls achieved more than a year of EFS. The most common complications during early treatment were acute hyperkalemia from rapid tumor cell lysis and infections due to prolonged marrow aplasia. Continuation chemotherapy was well tolerated. We conclude that VM-26 plus ara-C, added to each phase of an otherwise basic regimen of chemotherapy, will substantially improve prognosis in this high-risk form of childhood leukemia.

Published: February 2017

Thirty-nine patients with stage III and IV epithelial ovarian cancer who underwent second-look laparotomy (SLL) at New York University Medical Center and 11 eligible patients who did not undergo reexploration were retrospectively studied with follow-up from 24 to 105 months after diagnosis. Sixteen patients (41%) were found to have macroscopic disease, six (15%) microscopic tumor, and 17 (44%) no disease at SLL. Five of 22 patients who received further therapy based on positive SLL findings have remained without clinical evidence of disease 17 to 65 months after SLL. Nine of 17 patients with negative SLL, in whom treatment was stopped, recurred 8 to 52 months after SLL, five in extraperitoneal sites only. Five of 11 patients not undergoing SLL recurred 16 to 39 months after diagnosis, four intraperitoneally. There was no significant difference in survival between the second-look and no second-look groups for the period of study. Clinical trials are needed to determine if SLL influences longer-term survival and if continued treatment is indicated in a high-risk subgroup despite negative SLL. The value of SLL is limited by the efficacy of second line therapy. The role of routine SLL outside an investigational setting is questioned.

Twenty-two consecutive patients with high-grade, B-cell lymphomas related to the acquired immunodeficiency syndrome (AIDS) were accrued onto two sequential phase II studies, consisting of a standard regimen (M-BACOD, group no. 1, N = 13), or a novel, intensive regimen (group no. 2, N = 9), which included high-dose cytosine arabinoside (HD-Ara-C), and high-dose methotrexate (HD-MTX), in an attempt to prevent CNS relapse and improve response rates. Stage IV disease was present in 82%. Complete remission (CR) was achieved in seven of 13 patients (54%) in group no. 1, and in three of nine (33%) group no. 2 (P = NS). By multivariate analysis, the most significant factor in predicting response was a Karnofsky performance score (KPS) greater than 60 (P = .04). Three of the ten patients who achieved CR on either regimen have relapsed; in all, five of 13 patients (31%) in group no. 1 have achieved disease-free survival for more than 1 year, compared with one of nine (11%) in group no. 2. CNS progression occurred in six patients in group no. 2, and in two patients in group no. 1. Hematologic toxicity was significantly greater in group no. 2, and these patients had an increased risk of opportunistic infection (one in group no. 1 v seven in group no. 2; P less than .01). Survival was similar, with a median of 11 months in group no. 1 and 6 months in group no. 2. We conclude that the intensive regimen of combination chemotherapy described here is associated with significant risk of early death due to opportunistic infection in patients with AIDS-related lymphoma, and that progression in the CNS remains a major problem. Trials of combination chemotherapy of a less intensive nature, perhaps in combination with immunomodulators or antiretroviral agents should be explored.
P-glycoprotein in human sarcoma: evidence for multidrug resistance.

Published: February 2017

Overexpression of an immunologically conserved, cell-surface glycoprotein (P-glycoprotein) is consistently associated with multidrug resistance in cell lines in vitro. A preliminary survey of specimens from 12 solid tumor types in our laboratories indicates significant overexpression of P-glycoprotein in some sarcomas. When tested by immunoblotting with monoclonal antibodies directed against P-glycoprotein; tumors from six of 25 sarcoma patients displayed elevated levels of P-glycoprotein. Three of the sarcoma patients exhibiting P-glycoprotein had not previously been exposed to chemotherapy, implying that overexpression of this marker and possible concomitant multidrug resistance may not depend only on selection during prior drug treatments. The P-glycoprotein overexpression in the sarcoma specimens is evidence for the presence of multidrug resistant cells in these tumors; thus, our data suggest that this mode of resistance may have clinical significance in sarcoma patients.

Published: February 2017

Compliance with oral self-administered allopurinol (daily medication) and prednisone (intermittent medication) as well as compliance with monthly scheduled clinic appointments, were examined in 108 patients with newly diagnosed hematologic malignancy. Baseline levels of compliance (control group) were compared to results obtained after implementation of three intervention packages, whose aim was to increase compliance. The packages included combinations of education, home psychologic support and restructuring, and training in pill taking. A 24-hour profile of the two drugs and their metabolites was first determined. Serum samples were then obtained monthly over 6 months and analyzed for presence of the drugs. Control patients were fully compliant with allopurinol only 16.8% of the time. This rate increased significantly (44% to 48% of the time) for those who received any one of the intervention programs. With respect to prednisone, control patients were compliant 26.8% of the time, with no real improvement after interventions. Finally, self reports overestimated compliance by a factor of two when compared to drug analysis. The results indicated that full compliance with oral medications was remarkably low among our patients who have treatable and in some cases curable hematologic malignancy. However, compliance can be significantly improved by the use of various intervention packages.
Potentially curative surgery of colon cancer: patterns of failure and survival.

Published: February 2017

In an effort to determine the patterns of failure and survival of colon cancer, a retrospective review of 294 patients who underwent potentially curative surgery at the New England Deaconess Hospital (NEDH) was performed. For the entire group, the 5-year crude survival rate was 68% and the actuarial rate was 80%. Survival decreased with increasing bowel wall penetration by tumor and the presence of lymph node metastasis. Although survival varied with the tumor site, none of the differences was statistically significant. Other variables, including the grade of adenocarcinoma, size, and the type of surgery had a significant impact on survival. Patterns of failure, expressed as the actuarial incidence of first diagnosed failure at 5 years, were examined by stage and site. There was a trend toward increased failure with increasing bowel wall penetration by tumor and the presence of lymph node metastasis. Abdominal failure, either as the only site or as a component of failure, was the most common type of failure. When compared by site, patients with cecal carcinoma had a significantly lower incidence of local and distant failure than patients with disease in other selected sites. No differences in patterns of failure were seen in patients with carcinomas in the mobile sections of the colon compared with those who had disease arising in the nonmobile sections of the colon. These data may be useful in identifying those patients who might benefit most from adjuvant therapy.
Chemotherapy and hormonal therapy in combination.
Authors: Hug V , Thames H , Clark J
Published: February 2017

The advantage of adding hormones to chemotherapy for the treatment of patients with breast carcinoma is uncertain, and benefits and disadvantages have been reported. An analysis of published randomized clinical trials reveals that the growth function (differentiation-inducing function v mitogenic function) of the hormone used may determine the ultimate benefit of combined modality treatments.

Published: February 2017

Analysis of remission induction rates for 1,768 children (1.5 to 11 years) and 425 adolescents (greater than or equal to 11 years) with acute lymphoid leukemia (ALL), and of event-free survival times for 570 children and 147 adolescents, disclosed that adolescents fared significantly worse by both measures of treatment outcome (P = .0001). Adolescents with either T cell or non-T cell ALL entered remission significantly less often than did children (P = less than .02 and P = less than .001, respectively). Within each of the major immunophenotypes of ALL, adolescents had shorter duration of continuous complete remission: early pre-B (non-B, non pre-B, non-T) (P = .001), pre-B (P = .05), and T (P = .027). We compared the clinical characteristics of adolescents and children, and lymphoblast characteristics present at diagnosis to account for the inferior prognosis of adolescent patients. Adolescents had a higher incidence of T cell ALL (P = .0001) and thus a higher incidence of all T cell-associated characteristics. Adolescents with non-T, non-B ALL were more likely to be male (P = .044), and to have higher leukocyte counts (P = .002) and lower levels of IgG (P = .0003), IgA (P = .0001), and IgM (P = .002). Their leukemic cells had lower PAS scores (P = .0001), a higher incidence rate of L2 morphology by French-American-British (FAB) criteria (P = .001), common ALL antigen negativity (P = .0001), and hypodiploid or pseudodiploid karyotypes (P = .004). These findings clearly indicate an increased incidence of prognostically unfavorable clinical and biologic features in adolescents with ALL, providing a biologic explanation for their poor prognosis.
Chemotherapy-related toxicity in infants treated according to the Second National Wilms' Tumor Study.

Published: February 2017

Babies under 12 months of age have been included in the National Wilms' Tumor Study (NWTS) series of clinical trials. Undue chemotherapy-related toxicity was encountered early during the course of the second NWTS. The prescribed doses of actinomycin D (AMD), vincristine (VCR), and Adriamycin ([ADR] doxorubicin; Adria Laboratories, Columbus, OH) were therefore halved. The frequency of severe hematologic toxic episodes was reduced (30 of 64 or 47% for babies receiving full doses [FD], and six of 48 or 13% for those given reduced doses [RD]). Similar reductions in pulmonary and hepatic effects were noted, and treatment-related deaths were reduced from 6% to 0 for the FD and RD samples, respectively. These frequencies among RD babies were similar to those encountered in 530 older children administered FD. Reduction of dose did not compromise therapeutic effectiveness.

Published: February 2017

A total of 315 pathologically staged (PS) patients with IA and IIA Hodgkin's disease (HD) were treated with mantle and paraaortic irradiation, and evaluated for freedom-from-first relapse (FFR), survival, prognostic factors, and long-term complications. The 14-year actuarial FFR and survival were 82% and 93%, respectively, with a median follow-up time of 9 years. Mediastinal size was the only factor that predicted for a lower FFR, P less than .001. Forty-nine patients have developed recurrent HD. Thirty-six patients are disease-free following retreatment and only 13 patients have died of HD. Patients with mixed cellularity (MC) histology were more likely to relapse below the diaphragm (11%) as compared with patients with nodular sclerosis (NS) (5.1%) or lymphocyte predominant (LP) (3.6%) histology. These relapses were often associated with bulky pelvic nodal adenopathy and salvage treatment with chemotherapy alone often failed to control recurrent disease. Alternative diagnostic and therapeutic recommendations are presented for these patients. Thyroid abnormalities represented the most common long-term complication with an actuarial risk at 16 years of 37%. Major complications were rare. Mantle and paraaortic irradiation is associated with a high FFR and a low risk of complications and should remain standard treatment for early-stage HD.

Published: February 2017

Sixty-nine patients with hairy-cell leukemia (HCL) were treated with interferon alfa-2b (IFN) in a single-institution study. The dose used was 2 x 10(6) U/m2 self-administered subcutaneously three times weekly, for a planned treatment duration of 12 to 18 months. Of the 68 evaluable patients, the major response rate was 75%, with 13% complete responses (CRs) and 62% partial responses (PRs). An additional eleven patients (16%) had minor responses (MRs). Duration of response was denoted as failure-free survival (FFS), defined as the time from the end of IFN therapy to a need for further antileukemic therapy. Of the 60 responding patients followed after discontinuation of IFN, 27 have relapsed, requiring further therapy. The median actuarial FFS for these 60 patients is 25.4 months. All but five patients are alive, and the actuarial overall survival for the 69 patients is 91% +/- 4% at 4 years from the start of IFN. The best indicators of relapse were the neutrophil alkaline phosphatase (NAP) score and degree of residual bone marrow hairy cells (%HCL) at the completion of therapy. Patients with NAP less than 30 (n = 21) had the best prognosis (median FFS, 30.4 months), while those with NAP greater than or equal to 30 and %HCL less than or equal to 30 (n = 21) or %HCL greater than 30 (n = 16) had intermediate and poor prognoses, respectively (median FFS, 23.5 and 12.4 months) (P = .0005). Fourteen of the relapsing patients are evaluable for response to a second course of IFN, with seven PRs and four MRs. Stratified randomized trials are indicated to determine the role of maintenance therapy for responding patients.
The influence of symptoms of disease and side effects of treatment on compliance with cancer therapy.
Authors: Richardson J L , Marks G , Levine A
Published: February 2017

To provide a systematic analysis of how adverse symptoms of disease and side effects of cancer therapy relate to patient noncompliance with treatment, we interviewed 107 patients with hematologic malignancies at the initiation of therapy and 6 months later to collect information on the type, frequency, and difficulty of unpleasant physical effects experienced. Level of compliance was monitored (biochemically and with self-report) on a monthly basis for oral self administration of allopurinol and prednisone. Appointment-keeping to receive infused chemotherapy was also monitored. Nausea was the most frequent side effect experienced. Nausea, fever, and pain were the most difficult physical effects to tolerate when they occurred. Complex treatment regimens and severe diseases related to reports of more physical effects. Younger patients had a more difficult time dealing with these effects than did older patients. Neither the occurrence, frequency, or difficulty dealing with any of the effects related to noncompliance with either of the two self-administered medications. Difficulty with particular effects did relate to noncompliance with clinic appointments to receive infused chemotherapy.
Cisplatin as first-line therapy for metastatic breast cancer.
Authors: Sledge G W , Loehrer P J , Roth B J , Einhorn L H
Published: February 2017

Cisplatin has had only minimal activity when used as second- and third-line chemotherapy for metastatic breast cancer (MBC). There have been no phase II studies in the United States evaluating cisplatin in patients with MBC with no prior chemotherapy. We therefore treated 20 consecutive patients with cisplatin 30 mg/m2/d for four days every 3 weeks for a maximum of six courses. We obtained partial responses in nine of 19 evaluable patients (47%), with responses in liver, lung, and soft tissue indicator lesions. Our data suggest that cisplatin has substantial single-agent activity as front-line therapy in MBC, and should be considered for inclusion in first-line combination chemotherapy regimens.
Treatment with MOPP or ChlVPP chemotherapy only for all stages of childhood Hodgkin's disease.

Published: February 2017

Fifty-three children with Hodgkin's disease were clinically staged and treated with chemotherapy alone. Forty-six received mechlorethamine (Mustargen; Merk Sharpe & Dohme, West Point, PA), vincristine (Oncovin; Eli Lilly and Company, Indianapolis), procarbazine, and prednisolone (MOPP) and 7 chlorambucil, vinblastine, prednisolone, and procarbazine (ChlVPP). There were four events in the 38 children with stage I and II disease. One patient with massive mediastinal disease failed to remit and subsequently failed mantle irradiation and changes of chemotherapy. Another relapsed at the site of local disease and was salvaged with involved field irradiation and further courses of MOPP. Two other children died as a result of acute graft-v-host disease (GVHD) following transfusion. At autopsy there was no evidence of Hodgkin's disease. Fifteen children had stage III and IV disease and 14 achieved complete remission (CR) and none have relapsed. The child who failed to achieve remission died of virus infections. A mediastinal mass greater than 1/3 the thoracic width was present in 19 children of whom 18 achieved remission and none relapsed. An infradiaphragmatic presentation occurred in eight, all achieved remission and none relapsed. Overall at a median follow-up time of 45 months survival was 94%; the percent of patients without treatment failure was 92; and the percent without relapse was 98.
Malignancy-associated Sweet's syndrome: review of the world literature.
Authors: Cohen P R , Talpaz M , Kurzrock R
Published: February 2017

Sweet's syndrome is an acute febrile neutrophilic dermatosis in which approximately 20% of the reported patients have an associated cancer. We review the 79 patients with malignancy-associated Sweet's syndrome documented in the world literature. The most common underlying neoplasm was acute myelogenous leukemia (AML). Lymphomas, chronic leukemias, myelomas, myelodysplastic syndromes, and a variety of solid tumors have also been observed. The onset of Sweet's syndrome either preceded or coincided with the discovery of a previously undiagnosed cancer in greater than 60% of malignancy-associated Sweet's syndrome patients. In contrast to patients with the idiopathic form of the disease, those with a malignancy often presented with more severe cutaneous lesions, cytopenias, and/or immature cells in the peripheral blood. Extracutaneous sites of involvement included the eyes, muscles and joints, kidneys, lungs, and liver. All the manifestations of Sweet's syndrome improved dramatically with corticosteroid therapy, regardless of the response of the associated neoplasm to tumor-directed therapy.

Published: February 2017

The H5 program in clinical stage (CS) I to II supradiaphragmatic Hodgkin's disease (HD) was tailored to prognostic factors identified in former European Organization for the Research and Treatment of Cancer (EORTC) studies. Among the 494 adult patients included in the study, the 237 patients belonging to the favorable group (H5F) underwent a staging laparotomy (Sx) in order to select the patients who could be treated with limited radiotherapy (RT) only. Thus, 198 patients (84%) with negative laparotomy were treated with RT alone and randomized to either mantle irradiation (M) or extended field mantle plus para-aortic (M + PA) irradiation. Complete remission (CR) was achieved in 99% of the patients. There was no difference in the 6-year relapse-free survival (RFS) rate (74% and 72%, respectively) or survival rate (96% and 89%). Therefore, Sx helped to define those patients who could be treated with M alone in contrast to those who required more aggressive therapy. The 39 patients with positive laparotomy were treated as the unfavorable group (H5U) from onset and randomized to either total/subtotal nodal irradiation (TNI/STNI) or a sandwiched mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) X 3, M irradiation, MOPP X 3 protocol (3M). Although the RFS rate was higher in the 3M arm (100% v 53%; P = .002), the 6-year survival was not significantly different between the two arms (overall, 92%). In the 257 patients with initial unfavorable disease, the Sx was avoided. They were randomized to either TNI/STNI or 3M. In complete responders (96%), the 6-year RFS was 91% in the 3M arm and 77% in the TNI/STNI arm (P = .02). The pattern of failure differed in the two arms: the inverted Y and spleen irradiation controlled occult infradiaphragmatic disease better than MOPP; conversely, less patients begun on MOPP recurred in the involved mantle areas. The difference in 6-year actuarial total survival (TS) (89% and 82%; P = .05 in favor of the 3M arm) was not retrieved after exclusion of the unrelated deaths from the analysis. The two arms produced similar TS in patients under 40 years of age. TNI retains interest, especially in young men wishing to preserve fertility. The overall result shows that when treatment is tailored to initial prognostic factors, excellent results can be obtained in all patient subgroups at minimal morbidity and toxic cost.

Published: February 2017

Following observation of the predictive value of the histologic extent of tumor cell destruction after preoperative chemotherapy for metastasis-free survival (MFS) in osteosarcoma, a randomized study was undertaken with the aim of (1) sparing some patients the unpleasant side effects of highly toxic drugs like doxorubicin (DOX) and cisplatin (CPDD) by administering these drugs postoperatively only after poor response with a milder preoperative regimen, and (2) improving the prognosis of patients responding poorly to the initial treatment by use of a salvage chemotherapy postoperatively. The available patients were divided into two groups. Those in the study arm received a preoperative chemotherapy consisting of high-dose methotrexate (HDMTX) and the triple drug combination of bleomycin, cyclophosphamide, and dactinomycin (BCD) and were switched to DOX/CPDD postoperatively in case of poor response. DOX/CPDD was used besides HDMTX for initial treatment in the control arm, and BCD alternatively with CPDD/ifosfamide (IFO) for postoperative salvage treatment. The response rate of the study arm was significantly inferior to the control arm (26% v 60%; P less than .001). The actuarial 4-year MFS rate of poor responders after salvage chemotherapy also was poorest in the study arm (41%); it was unchanged in the control arm (53%) as compared with that of poor responders from the COSS-80 study without salvage chemotherapy (52%). The actuarial 4-year MFS rate of good responders was 73% in the study arm, 79% in the control arm, and not significantly different from that of the COSS-80 study (84%), although postoperative chemotherapy of good responders had been markedly shortened as compared with the COSS-80 study. The actuarial 4-year MFS rate of the study arm as a whole was inferior to that of the control arm (49% v 68%; P less than .1) and also inferior to the COSS-80 study (68%; P less than .01), indicating a failure of the employed salvage strategy in general and especially of the effort to restrict the use of the very effective but highly toxic drugs DOX and CPDD to patients resistant to a less toxic initial treatment.
Teniposide in the treatment of leukemia: a case study of conflicting priorities in the development of drugs for fatal diseases.

Published: February 2017

Teniposide, a semisynthetic epipodophyllotoxin, was found to be highly active against murine leukemias, and the combination of teniposide with cytosine arabinoside (ara-C) was curative in murine leukemia models. The antitumor activity in preclinical models prompted introduction of teniposide into the clinic in 1971. Although teniposide as a single agent rarely produced a complete remission in heavily pretreated leukemia patients, teniposide plus ara-C produced complete remissions in some patients with refractory and relapsed acute lymphoblastic leukemia (ALL). Innovative front-line and salvage regimens using teniposide have been developed that incorporate a multi-drug strategy with early intensification, rotation of drug combinations in maintenance, and regional therapy in an effort to improve the cure rate in leukemia. However, as the complexity of these regimens increases, the contribution of an individual component such as teniposide becomes less clear. Although some of these regimens for newly diagnosed and relapsed ALL are now thought to represent the best available therapy, teniposide remains an investigational agent. In this review, we outline and discuss the conflicts arising from the need to answer drug-specific issues, and, at the same time, facilitate the implementation of innovative, curative regimens.
A randomized trial of fluorouracil and folinic acid in patients with metastatic colorectal carcinoma.

Published: February 2017

We determined the therapeutic effect of fluorouracil (5-FU) in combination with folinic acid (FA) in patients with measurable recurrent or metastatic carcinoma of the colon or rectum by comparing it to standard 5-FU therapy in a prospective randomized controlled trial. Patients were randomized to receive either FA, 200 mg/m2/d for five consecutive days, or nothing. All patients received 5-FU, 370 mg/m2/d for five days on the first course, with subsequent dose modifications to maintain equal toxicity in the two arms. One hundred thirty patients were entered on trial and only five were excluded from the analysis because they did not meet the eligibility criteria or they refused therapy after randomization. The two treatment arms were balanced for 11 clinical characteristics. Patients were evaluated for response at the end of every two treatment courses and toxicity after every course of therapy. Median follow-up was 1.45 years. Dose-limiting toxicity was mucositis and diarrhea on this treatment schedule, although neutropenia was apparent. The response rate was 33% (21 of 63 patients) in the 5-FU and FA arm and was 7% (four of 61 patients) in the 5-FU arm (P less than .0005). Time to disease progression was significantly different in the combination arm as compared with the single-agent arm (P = .023). Overall survival was significantly longer for patients treated with 5-FU and FA as compared with those receiving 5-FU alone (P = .05). The median survival was 12.6 months for patients receiving the combination, and 9.6 months for those receiving 5-FU alone. Our results indicate that the combination of 5-FU and FA is effective treatment for patients with metastatic or recurrent carcinoma of the rectum and colon who have not received prior chemotherapy.
Combined radiotherapy and chemotherapy in stage T3 and T4 nasopharyngeal carcinoma in children.

Published: February 2017

Twelve children younger than 16 years affected by undifferentiated nasopharyngeal carcinoma (NPC) with advanced primary tumor (T3, T4) were treated with chemotherapy consisting of Adriamycin (ADM [doxorubicin; Adria Laboratories, Columbus, OH]), vincristine (VCR), and cyclophosphamide (CYC), and radiotherapy. Preradiation chemotherapy produced partial responses in eight of ten evaluable patients. Eleven of 12 patients achieved a complete response following radiotherapy. The actuarial 3-year continuous relapse-free survival (CRFS) was 75%. This represents a significant improvement when compared with the 8% rate obtained in a previous series of patients treated with radiotherapy either with or without adjuvant CYC.
Pharmacokinetics and metabolism of epidoxorubicin and doxorubicin in humans.

Published: February 2017

Pharmacokinetics of doxorubicin (DOX), epidoxorubicin (EPI), and their metabolites in plasma have been performed in eight patients receiving 40 to 56 mg/m2 of both anthracyclines as a bolus injection in two sequential cycles. Terminal half-life and volume of distribution appeared to be smaller in case of EPI, whereas plasma clearance and cumulative urinary excretion was larger in comparison to DOX. The major metabolite of DOX was doxorubicinol (Aol) followed by 7-deoxy-doxorubicinol (7d-Aolon). Metabolism to glucuronides was found in case of EPI only. The area under the curves (AUC) of the metabolites of EPI decreased in the order of the glucoronides E-glu greater than Eol-glu, 7d-Aolon greater than epirubicinol (Eol). The AUC of Eol was half of the value in its counterpart Aol. In the case of EPI, the AUC of 7d-Aolon was twice the level of that of the corresponding metabolite of DOX. The terminal half-lives of the cytostatic metabolites Aol and Eol were similar, but longer than the corresponding values of their parent drugs. Half-lives of the glucuronides (E-glu, Eol-glu) were similar to the half-life of their parent drug. 7d-Aolon had a somewhat shorter half-life in comparison to both DOX and EPI. Approximately 6.2% of EPI and 5.9% of DOX were excreted by the kidney during the initial 48 hours. Aol was found in the urine of patients treated with DOX, whereas Eol, E-glu, and Eol-glu were detected in urine of patients treated with EPI. The cumulative urinary excretion appeared to be 10.5% for EPI and its metabolites, and 6.9% for DOX and its metabolite. The plasma concentration v time curves of (7d)-aglycones showed a second peak between two and 12 hours after injection, suggesting an enterohepatic circulation for metabolites lacking the daunosamine sugar moiety. The plasma concentrations of the glucuronides were maximal at 1.2 hours for E-glu and 1.9 hours for Eol-glu. All other compounds reached their maximum plasma concentration during the first minutes after the administration of DOX and EPI. Deviating plasma kinetics were observed in one patient, probably due to prior drug administration.

From 1965 to 1985, 262 patients with malignant pleural mesothelioma were treated with cytostatics only; radiotherapy (RT); RT and cytostatics; or decortication plus RT plus cytostatics. The median survival (MS) from diagnosis was 9.6 months. This was similar for all comparable treatment groups. In a univariate analysis, significant favorable prognostic factors were good performance status (PS), duration of symptoms greater than 6 months at the time of diagnosis, early stage of disease, white race, and female sex. In a multivariate analysis, PS, race, duration of symptoms, and stage were of significance for a favorable prognosis. Age, pain as first symptom, histologic subtype, and RT dose were not of prognosis significance in this study. The stepwise addition of treatment modalities did not increase survival, which remained the same as that reported for untreated patients. Therefore, phase II trials of new agents offer the only hope for advance in the treatment of this disease.

We added high-dose oral leucovorin to the combination of cisplatin and fluorouracil (5-FU) to assess the efficacy of this regimen in the treatment of patients with head and neck cancer. Cisplatin, 100 mg/m2, was followed by a 5-FU continuous infusion at 600 mg/m2/d for five days. Leucovorin, 50 mg/m2, was administered at the start of cisplatin and every six hours throughout the duration of the 5-FU infusion. The dose of 5-FU was escalated to 800 mg/m2 and 1,000 mg/m2 according to observed toxicity. In a second phase of the study, the dose of leucovorin was escalated to 50 mg/m2 every four hours. A total of 25 patients were registered: 23 had recurrent disease after extensive prior treatment; and two had newly diagnosed metastatic disease. The maximally tolerated dose of 5-FU was 800 mg/m2/d with leucovorin administered every six hours. Toxicities at that level included mild to moderate myelosuppression and dose-limiting mucositis in the previously irradiated field. Identical toxicities were observed when administering 800 mg/m2/d of 5-FU with leucovorin every four hours. Eighteen patients were evaluated for response: one had a pathologic complete response; nine had a partial response (including four who received prior cisplatin and 5-FU as induction chemotherapy); and eight patients failed to respond. The mean peak and trough plasma leucovorin concentrations were 2.61 (+/- 1.07) mumol/L and 2.46 (+/- 0.95) mumol/L with administration of the drug every six hours, and 2.75 (+/- 2.15) mumol/L and 2.52 (+/- 1.48) mumol/L with administration every four hours. We conclude that the combination of cisplatin, 5-FU, and leucovorin has activity in the treatment of recurrent head and neck cancer. The maximally tolerated dose of 5-FU in this study was 800 mg/m2/d, with mucositis in previously irradiated sites being dose-limiting. Plasma leucovorin concentrations exceeding 1 mumol/L are achieved following oral administration of this drug.

This report deals with a randomized prospective multicentric clinical trial in childhood rhabdomyosarcoma (RMS) conducted to evaluate the toxicity and the effectiveness of dactinomycin (ACT-D) administered as high, single doses v five-day, divided doses administered in combination with vincristine (VCR) and cyclophosphamide (CYC). Fifty-five group III evaluable patients (pts) less than 15 years of age with tumor size greater than 5 cm in diameter, without high-risk features of CNS involvement, and 15 group IV RMS pts were randomized to receive VAC as primary chemotherapy (CT): VCR, 1.5 mg/m2 intravenously (IV) days 1 and 8; CYC, 275 mg/m2 IV days 1 through 5; and ACT-D, 0.45 mg/m2 IV days 1 through 5 every 28 days for three cycles (33 pts), or VAC-M: CYC, 150 mg/m2 intramuscularly (IM) days 1 through 7; VCR, 2.0 mg/m2 IV day 8; and ACT-D, 1.7 mg/m2 IV day 8 every 21 days for four cycles (37 pts). Major responses (complete plus partial responses [PR]) were obtained in 67% of the VAC pts and in 70% of the VAC-M pts. Toxic effects were low, and no increased toxicity was observed in pts treated with high, single-dose ACT-D. These results confirm the effectiveness and feasibility of single, high doses of ACT-D with the advantage of requiring less pt hospitalization.

A randomized clinical trial was performed to determine if combination hormonal therapy with tamoxifen (TAM) and fluoxymesterone (FLU) was more efficacious than TAM alone for the treatment of postmenopausal women with metastatic breast cancer. Patients failing TAM could subsequently receive FLU. The dose of both drugs was 10 mg orally twice daily. Objective responses were seen in 50 of 119 TAM patients (42%) and 63 of 119 TAM plus FLU patients (53%) (one-sided P = .05). Time to disease progression distributions were better for TAM plus FLU (median, 350 days v 199 days), but the log rank test only approached statistical significance (one-sided P = .07). Duration of response and survival distributions were similar between the two treatment arms. Toxicities, in terms of androgenic side effects, were greater on the TAM plus FLU regimen. Fifty-two patients are evaluable for response with FLU following TAM and 21 (40%) have achieved a response. We conclude that the advantages in terms of response rate and time to progression observed with TAM plus FLU probably represent a biological effect, but are not of sufficient magnitude to justify the routine clinical use of this combination given the lack of survival advantage and side effects encountered.

Published: February 2017

The presenting features and clinical outcome of acute nonlymphoblastic leukemia (ANLL) in infants and older children were compared to identify any differences that might suggest methods to improve therapy. Twelve of the 29 infants were boys and 17 were girls, with ages ranging from two days to 12 months (median, 7 months). By comparison with 222 patients greater than 1 year of age, infants were significantly more likely to have monoblastic or myelomonoblastic leukemia (P less than .0001), chloroma (P less than .0001), marked hepatomegaly (P = .001), and high leukocyte count (P = .005) and were less likely to have Auer rods (P less than .001). Each of these features except leukocyte count showed an association with infant ANLL in a multivariate analysis. Twenty-four (83%) of the infants attained a complete remission, a rate that was not significantly different from that of the older children. Even though infants had a significantly higher CNS relapse rate (P = .003), their event-free survival times were no different than those of older children (P = .74). Ten of the infants remain in initial complete remission for 5+ to 112+ months (median, 52+ months). Infants with ANLL did not have a poorer prognosis than older patients in our study; future protocols for this age group should emphasize more effective systemic therapy, preferably including an epipodophyllotoxin, as well as improved treatment for subclinical CNS leukemia.

Labeling indices (LI) provide a rapid measure of the bone marrow (BM) plasma cell proliferation rate and are useful in the diagnosis and prognosis of monoclonal gammopathies. Because circulating B cells may be a part of the neoplastic clone, we examined peripheral blood B cells that were producing the same cytoplasmic light chain isotype as the patient's monoclonal; protein (M-protein) and determined the peripheral blood LI (PBLI) by a two-color immunofluorescence bromodeoxyuridine method. The 105 patients studied were divided into three disease activity groups by standard clinical criteria. Median PBLI was 0.2% for the 29 patients with inactive monoclonal gammopathies (monoclonal gammopathy of undetermined significance [MGUS] and smoldering multiple myeloma [SMM]), 0.8% for the 35 patients with new, untreated multiple myeloma (MM), and 1.7% for the 41 patients with relapsed MM. These differences between groups were statistically significant (P less than .001, Wilcoxon). Four patients had high PBLI but clinically inactive gammopathy at the time of study, and all developed active MM within 6 months that required treatment. In 92 patients a BMLI was performed simultaneously with the PBLI (rank correlation coefficient, 0.69). In patients with new, untreated MM, use of both tests identified 72% of patients (23 of 32) with high LI, rather than 56% (18 of 32) by BMLI alone or 63% (20 of 32) by PBLI alone. These results suggest that PB B cells bearing the same cytoplasmic light chain isotype as the monoclonal protein are part of the malignant clone and can be kinetically active. The LI of these cells can provide a measure of disease activity and may help to differentiate active from inactive disease.
Relative worth of estrogen or progesterone receptor and pathologic characteristics of differentiation as indicators of prognosis in node negative breast cancer patients: findings from National Surgical Adjuvant Breast and Bowel Project Protocol B-06.
Authors: Fisher B , Redmond C , Fisher E R , Caplan R
Published: February 2017

This study correlates the disease-free survival (DFS), distant disease-free survival (DDFS), and survival (S) of 1,157 histologically node negative breast cancer patients with the estrogen and/or progesterone receptor (ER, PR) and with the nuclear or histologic grade (NG, HG) of their tumors. All were treated by operation without systemic adjuvant therapy. The DFS, DDFS, and S were significantly greater (P = .005, .004, less than .001) in patients with ER positive than ER negative tumors but the magnitude of the differences after 5 years of follow-up was slight (8% in both DFS and DDFS and 10% in S). Differences of that magnitude are insufficient to discriminate clearly between patients who should or should not receive systemic therapy. As with ER, there were outcome differences in favor of PR positive tumors but only in S was the difference significant (8% at 5 years; P = .002). When combined with ER, PR made no independent contribution in the outcome prediction. Regression analysis indicated that NG was the most important single marker of outcome. The prognosis of women with unknown ER or PR was equivalent to or better than that in those with ER or PR positive tumors. This finding seems to be related to tumor size in that a higher proportion of tumors with unknown receptors were less than 1.0 cm, thus having insufficient tissue for analysis. Our findings disclose that in node negative breast cancer patients, NG is a better marker of prognosis than is tumor ER, and that PR is of little or no value. Tumor NG may also be useful for selecting the type of systemic therapy to be used in these patients.

Seventeen patients received high-dose therapy with autologous bone marrow transplantation (ABMT) when in partial response after induction therapy. There were 11 children and six adults between 3 and 57 years old. Twelve patients were determined to have high-grade lymphoma (ten Burkitt's and two lymphoblastic), and five had intermediate-grade diffuse lymphoma. Ten patients had surgically proven active disease in the abdomen, two had active disease in the bone marrow, and five persistent neurological symptoms. The time interval between diagnosis and ABMT was 2-10 months (median 4 months). Two patients died of progressive disease and two others died while in complete remission (CR) because of toxicity. Thirteen of 17 are still alive and disease free with a median observation time of 2 years. Morbidity was high with 6/17 life threatening reversible complications but overall survival is 75% at 24 months in a group of patients clearly defined as having a very bad prognosis in previous studies.

Published: February 2017

Twenty-one patients with tumor stage mycosis fungoides (MF) with or without lymph node (LN) involvement, were treated with total skin electron beam irradiation (TSEB) followed by six monthly cycles of systemic chemotherapy (CT) of either mechlorethamine (HN2) or cyclophosphamide (CTX) with vincristine (VCR), procarbazine, and prednisone (PRD) (COPP or MOPP). All patients had complete clearing of the skin after TSEB. However, while receiving chemotherapy, two patients developed visceral involvement and eight patients relapsed with limited cutaneous plaques (LCP). The median duration of remission was 12 months from the completion of TSEB, and all patients relapsed with cutaneous plaques within 25 months. Complete remission was again achieved using additional electron irradiation and maintenance therapy in all but one patient. Multiple cutaneous recurrences occurred in all patients. Median survival from the initiation of TSEB is 6 years. Five patients are living beyond 8 years (four off treatment without disease for 1 to 7 years). LN involvement did not influence initial response or survival. Combined modality therapy for tumor stage MF using TSEB followed by systemic CT and subsequent maintenance therapy may lead eventually to prolonged disease-free survival (DFS) in selected patients.
