Published: February 2017

Between Jan 1, 1968, and Dec 31, 1980, 108 previously untreated patients with Hodgkin's disease pathologic stages (PSs) IA (29 patients) and IIA (79 patients) initially received radiotherapy alone. One postoperative death (due to pulmonary embolus) (0.9%) occurred, with one serious complication (0.9%). Between 1968 and 1973, patients were randomized to receive either involved field radiation treatment (RTIF) or extended field radiation treatment (RTEF). Since 1973 all patients have received RTEF, 4,000 cGy in four to five weeks, with a median follow-up of 7.4 years. Complete remission (CR) was achieved in 102 patients (94.4%), with no significant difference according to treatment or stage. Of the complete responders, 25 patients relapsed: 5/15 RTIF and 20/87 RTEF (P = .6). Twenty-one of 25 relapsing patients achieved a second CR. Disease free survival rates at five and ten years constituted: PS IA, 78.6% for both; PS IIA, 74.8% and 73.1% (P = .6); RTEF, 76.7% for both; RTIF, 73.3% and 66.7% (P = .7). Eighteen patients have died: eight of recurrent lymphoma, two of pulmonary embolus, one each of myocardial infarction, pulmonary fibrosis, and acute nonlymphocytic leukemia (ANLL) (following salvage chemotherapy), and one of diffuse histiocytic lymphoma (DHL). Four patients died in remission of unrelated causes. Actuarial survival rates at five and ten years constituted: PS IA, 95.7% and 72.4%; PS IIA, 89.6% and 81.4% (P = .3); RTIF, 93.7% for both; RTEF, 90.7% and 71.2% (P = .2). Age, sex, number of sites, and mediastinal involvement did not influence the outcome. Acute toxicity was modest and more frequent among those receiving RTEF (P = .08). Chronic toxicity (onset more than 30 days after completion of treatment) was identified in 16 patients: 1/16 RTIF; 15/92 RTEF (P = .5). Three patients developed a second malignancy: one carcinoma of the cervix in situ; one ANLL (following salvage chemotherapy); and one DHL of the stomach. At least 75% of patients with PS IA and IIA Hodgkin's disease were cured by radiation alone, with a risk of secondary malignancy following radiation alone of 0.9%. Since the majority of relapsing patients were successfully salvaged by chemotherapy, radiation alone appears to be the initial treatment of choice in this group of patients.
The importance of an isolated central nervous system relapse in children with acute lymphoblastic leukemia.
Authors: George S L , Ochs J J , Mauer A M , Simone J V
Published: February 2017

We assessed the influence of an initial isolated meningeal relapse on treatment outcome in 839 children with acute lymphoblastic leukemia (ALL) who were admitted to St Jude Children's Research Hospital (Memphis) from mid-1967 through mid-1979. The patients were entered in a series of five clinical trials (Total Therapy Studies V through IX), each designed to test one or more modifications of treatment for ALL. Two groups were compared: 699 children who received CNS prophylaxis (2,400-rad craniospinal irradiation or 2,400-rad cranial irradiation plus intrathecal methotrexate) v 56 who did not. Our results, obtained with a time-dependent covariate model and a matching technique, indicate a 2 to 3.5-fold increase in the risk of hematologic relapse or death among patients who experienced an isolated CNS relapse compared with similar patients (matched for leukocyte count and length of complete remission) who remained free of CNS involvement. Of the 107 children with an initial isolated CNS relapse, 89 (83%) have died or have had a subsequent relapse. There was no detectable difference in the rate of hematologic relapse or death after a CNS relapse between patients who had received preventive therapy and those who had not. We conclude that CNS prophylaxis is important both for the prevention of initial CNS leukemia and for reducing the risk of hematologic relapse or death subsequent to a CNS relapse.
Intraperitoneal chemotherapy with high-dose cisplatin and cytosine arabinoside for refractory ovarian carcinoma and other malignancies principally involving the peritoneal cavity.
Authors: Markman M , Cleary S , Lucas W E , Howell S B
Published: February 2017

Sixty-two patients with refractory ovarian carcinoma or other malignancies principally confined to the peritoneal cavity were treated with an intraperitoneal combination chemotherapy regimen consisting of cisplatin (100 mg/m2 or 200 mg/m2) and cytosine arabinoside (4 X 10(-3) mol/L or 10(-2) mol/L). Sodium thiosulfate was simultaneously administered intravenously (IV) to protect against cisplatin-induced nephrotoxicity. Sixteen of 52 evaluable patients demonstrated evidence of a clinical response including 14 (36%) of 39 with refractory ovarian carcinoma. Systemic toxicity was not severe except for cisplatin-induced emesis and a single episode of major renal insufficiency. Dose-limiting toxicity was bone marrow suppression with cytosine arabinoside administered at 10(-2) mol/L. We conclude that combination intraperitoneal therapy with high-dose cisplatin and cytosine arbinoside can be safely administered with objective tumor responses observed in patients with ovarian carcinoma refractory to front-line chemotherapy and in occassional individuals with other malignancies principally confined to the peritoneal cavity.
Comparison of CAF versus CMFP in metastatic breast cancer: analysis of prognostic factors.
Authors: Cummings F J , Gelman R , Horton J
Published: February 2017

One hundred fifty-five eligible women with metastatic breast cancer were randomly allocated to receive monthly cycles of either CMFP (cyclophosphamide, methotrexate, 5-fluorouracil, prednisone) or CAF (cyclophosphamide, doxorubicin, 5-fluorouracil), and 12 patients were studied to evaluate the effects of additional Corynebacterium parvum immunotherapy. Overall response rates of 53% were seen with CMFP and CAF. CAF was associated with significantly more complete responses than CMFP (17% v 5%). However, CAF therapy was administered for eight months and CMFP for six months. Only 13% of the CAF patients had a complete response during the first six months of chemotherapy, and this was not significantly different from the complete response rate on CMFP. The median response durations (CMFP, 6.3 months; CAF, 11.0 months), times to treatment failure (CMFP, 5.7 months; CAF, 7.8 months), and survival times (CMFP, 15.8 months; CAF, 18.6 months) were not statistically different. Other investigators who have compared CAF to CMF-containing regimens have reported a large advantage in CAF therapy among patients with "good risk" sites of metastases (local-regional recurrence, bone, lung nodules). Such a finding was not confirmed by our study: in multivariate analyses the groups associated with an advantage for CAF tended to have a poorer prognosis than the groups associated with an advantage for CMFP. There was significantly more nausea and vomiting after CAF treatment, and CMFP treatment was associated with significantly more edema, Cushingoid features, fever, and eye symptoms.
High-dose cytosine arabinoside therapy with and without anthracycline antibiotics for remission reinduction of acute nonlymphoblastic leukemia.
Authors: Herzig R H , Lazarus H M , Wolff S N , Phillips G L , Herzig G P
Published: February 2017

Seventy-eight patients with acute nonlymphoblastic leukemia in relapse were treated with high-dose cytosine arabinoside (3 g/m2 intravenously (IV) every 12 hours for 12 doses) alone, or with three days of anthracycline antibiotics (doxorubicin 20 mg/m2 or daunorubicin 30 mg/m2 IV daily) after completing the course of cytosine arabinoside. Consolidation and maintenance therapy was not given. When anthracyclines were added there was no increase in frequency or severity of nonhematologic toxicity including conjunctivitis, photophobia, dermatitis, cerebellar dysfunction, and gastrointestinal disturbance. All 78 patients achieved aplasia of the bone marrow. Five patients in each group died before bone marrow recovery. The use of anthracyclines did not prolong bone marrow recovery, with both groups demonstrating adequate granulocyte and platelet counts about four weeks after beginning treatment. Forty-one (53%) of the total 78 patients achieved a complete remission. In patients not clinically resistant to conventional-dose cytosine arabinoside, both regimens were equally effective inducing a complete remission (high-dose cytosine arabinoside alone, 12/19 [63%]; with anthracycline, 11/17 [65%], P = .270); in patients clinically resistant, the regimen including anthracycline was superior (15/27 [56%] v 3/15 [20%], P = .022). The duration of unmaintained response was similar (median, five months), but the longest remissions occurred when anthracyclines were used. Thus, high-dose cytosine arabinoside is effective in producing remissions in relapsed patients with acute nonlymphoblastic leukemia, and the addition of an anthracycline enhances this effect.
Randomized trial of three cisplatin dose schedules in squamous-cell carcinoma of the cervix: a Gynecologic Oncology Group study.

Published: February 2017

The Gynecologic Oncology Group has conducted a randomized prospective trial comparing cisplatin 50 mg/m2 every 21 days (regimen 1), 100 mg/m2 every 21 days (regimen 2), and cisplatin 20 mg/m2 for five consecutive days repeated every 21 days (regimen 3). Four hundred ninety-seven evaluable patients have been accrued on this study. The response rates were 20.7%, 31.4%, and 25.0%, for regimens 1, 2, and 3, respectively; the complete remission rates were 10.0%, 12.7%, and 8.6% for regimens 1, 2, and 3, respectively. The median duration of response ranged from 3.9 to 4.8 months, the median progression-free interval from 3.7 to 4.6 months, and the median survival time from 6.1 to 7.1 months. The difference in response rates for regimens 1 and 2 is statistically significant (P = .015) but less than the magnitude originally considered clinically significant. The differences in complete remission rates, response duration, progression-free interval, and survival times are not statistically significant. The following types of toxicity were observed: serum creatinine level greater than 2 mg/dL and/or BUN level greater than 40 mg/dL was 7%, 14%, and 17% on regimens 1, 2, and 3, respectively; leukocyte count less than 4,000/microL was 27%, 44%, and 41% on regimens 1, 2, and 3, respectively. Nausea and vomiting occurred in 74 patients (83%). The regimen consisting of a 100-mg/m2 single dose has produced a statistically significant higher response rate than the 50 mg/m2 regimen while producing no appreciable differences in complete remission rate, response duration, progression-free interval, or survival. In addition, the higher dose regimen was associated with greater myelosuppression and nephrotoxicity.
Comparison of intra-arterial cis-diamminedichloroplatinum II with high-dose methotrexate and citrovorum factor rescue in the treatment of primary osteosarcoma.

Published: February 2017

A randomized two-arm study was undertaken to determine relative tumoricidal effects of intra-arterial cis-diamminedichloroplatinum II (I/A-CDP) and high-dose methotrexate with citrovorum factor rescue (MTX-CF) in the treatment of the primary tumor in patients with osteosarcoma. Responses were evaluated by clinical, radiographic, angiographic, and pathologic parameters. Fifteen patients were randomized to receive MTX-CF and 15 to I/A-CDP. In the MTX-CF arm there were four responses (three complete responses, one partial response) whereas in the I/A CDP arm there were nine responses (seven complete responses, two partial responses). Two patients who failed MTX-CF and requested alternative treatment with I/A-CDP also responded. The total I/A-CDP response was 11/17.
Antiemetic efficacy of high-dose dexamethasone versus placebo in patients receiving cisplatin-based chemotherapy: a randomized double-blind controlled clinical trial.

Published: February 2017

The antiemetic effect of short courses of high-dose dexamethasone was compared with that of placebo in 64 patients receiving cisplatin-based cancer chemotherapy, in a double-blind randomized clinical trial. All patients were receiving cisplatin for the first time. Dexamethasone was given intravenously (IV) at a dose of 20 mg, two hours before and 3, 6, 9, and 12 hours after chemotherapy. Patients were crossed over to dexamethasone on the second cycle of chemotherapy if they experienced unacceptable gastrointestinal (GI) toxicity after initial treatment with placebo. Nine of 32 patients receiving dexamethasone and seven of 32 patients receiving placebo did not vomit. The median duration of nausea was significantly shorter (one-half hour) for the dexamethasone-treated group compared with that of placebo (31/2 hours). The number of patients who experienced unacceptable GI toxicity was significantly greater (53%) for the placebo patients than for those treated with dexamethasone (25%). Patients crossing over to dexamethasone after initially receiving placebo had a median duration of nausea of 11/2 hours and 24% did not vomit, results comparable to the first treatment group. We conclude that high-dose dexamethasone is only minimally effective as an antiemetic agent in patients receiving cisplatin-based chemotherapy.
Metoclopramide: dose-related toxicity and preliminary antiemetic studies in children receiving cancer chemotherapy.

Published: February 2017

Prior studies in adults have shown that metoclopramide (MCP), when given in high intravenous (IV) doses (2 mg/kg), is a highly effective antiemetic for chemotherapy-induced vomiting. It is well-tolerated in older adults, but younger adults have an increased disposition to acute extrapyramidal reactions (EPRs). Before studying the efficacy of MCP as an antiemetic in children, we first had to establish the safe dose range. We performed a dose-increase MCP toxicity study in children receiving highly emetic chemotherapy such as cisplatin (120 mg/m2) or cyclophosphamide (greater than 900 mg/m2), beginning with a dose of 0.2 mg/kg and increasing the dose in nine steps to 3 mg/kg. MCP was given every two hours for four doses beginning one-half hour before chemotherapy. To reduce the incidence of EPRs, we added concomitant diphenhydramine. In MCP doses less than 2 mg, toxicity was minimal. In doses greater than or equal to 2 mg, 4/27 (15%) had EPRs and 9/27 (33%) had akathisia. Children who received two consecutive days of MCP had a higher frequency of EPRs. Metoclopramide (2 mg/kg) had promising antiemetic efficacy in a preliminary nonrandomized trial. Chemotherapy-experienced children vomited fewer than five times in 9/21 (43%) trials, and new patients vomited fewer than five times in 7/10 (70%) trials. MCP will become more useful as an antiemetic in children if better measures to prevent EPRs can be developed. Chemotherapy-induced emesis has the same negative implications in children as it does in adults and optimum antiemetic regimens can only be discovered by conducting randomized clinical trials in children.
Selection bias in clinical trials.

Published: February 2017

Of 90 patients with intermediate or high-grade sarcoma eligible for a randomized trial of adjuvant doxorubicin (Adriamycin, Adria Laboratories, Columbus, Ohio), 48 were not entered: 24 (27%) by physician's choice and 24 refused randomization. Sixty-five percent of lower stage patients were randomized compared with 37% of those with higher stage (P = .02). Patients with extremity lesions were more frequently offered participation in the study (P = .07). Patients with lower stage lesions accepted randomization more readily than those with higher stage lesions (P = .01). As predicted by the higher stage and percentage of central lesions, the disease-free survival of nonrandomized patients was inferior to that of randomized patients (P = .15). Thus, patients at high risk appeared to avoid randomization and adjuvant doxorubicin in this trial, resulting in an inferior disease-free survival for the nonrandomized control group. Important questions generally require randomized trials that reliably determine relative treatment differences. If, however, the patients in a clinical trial are not representative of the entire patient population because of patient and physician selection biases, the generalizability of the results to the entire patient population may be compromised. For example, the prognosis of the general population cannot necessarily be inferred from the selected group in the study. In this study, the randomized and nonrandomized series yielded differing conclusions regarding treatment efficacy, even when an adjustment was made for known prognostic facts.
Low-dose deoxycoformycin in lymphoid malignancy.
Authors: Grever M R , Leiby J M , Kraut E H , Wilson H E , Neidhart J A , Wall R L , Balcerzak S P
Published: February 2017

Deoxycoformycin (dCF), a potent inhibitor of adenosine deaminase (ADA), was explored for its antineoplastic potential in 28 patients with advanced lymphoid malignancy. Both normal and malignant B lymphocytes have low levels of ADA activity, and low doses of dCF profoundly inhibit this enzyme in the peripheral blood of patients with chronic lymphocytic leukemia (CLL). The low doses of dCF administered in this trial (4 mg/m2) were not associated with prohibitive toxicity. Five of 28 patients had an objective response. Four additional patients had clinical improvement. No significant difference in the pretreatment ADA activity existed between responding patients and treatment failures. The demonstration of responses to dCF following failure on standard alkylating agents suggests that dCF may not be cross-resistant with current agents used to treat CLL. Additional studies should be pursued using low-dose dCF in patients with advanced malignancy.
A systemic lymphoproliferative disorder with morphologic features of Castleman's disease: clinical findings and clinicopathologic correlations in 15 patients.

Published: February 2017

Fifteen patients (11 males, four females; median age 57) manifested a disease characterized by (1) the histopathologic features of Castleman's disease, plasma cell type, in lymph node biopsies; (2) predominantly lymphadenopathic disease, involving multiple, preferentially peripheral nodal groups; (3) varied manifestations of multisystemic involvement (such as constitutional symptoms; splenomegaly and hypergammaglobulinemia; elevated ESR, anemia, and thrombocytopenia; hepatomegaly and altered liver function tests (LFTs); signs of renal disease); and (4) idiopathic nature. Two main patterns of evolution were recognized: persistent, with sustained clinical manifestations, and episodic, with recurrent exacerbations and remissions. Seventy-three percent of patients had infectious complications, and 27% developed malignancies. Complete remissions were obtained occasionally with antineoplastic agents and with splenectomy but not with glucocorticosteroids alone. The median survival time is 30 months; 60% of patients have died. Median follow-up in the six surviving patients is 97+ months. A review of 50 cases in the literature revealed similar clinical and laboratory features. Despite some similarities with autoimmune diseases, the main features of this process seem to best fit a hyperplastic-dysplastic lymphoid disorder in a setting of immunoregulatory deficit.
Leydig cell function in boys following treatment for testicular relapse of acute lymphoblastic leukemia.
Authors: Blatt J , Sherins R J , Niebrugge D , Bleyer W A , Poplack D G
Published: February 2017

Current practice for achieving local control of testicular relapse in males with acute lymphoblastic leukemia (ALL) includes the use of 2,400-rad testicular radiation. Although this therapy is known to cause germ cell depletion, it has been assumed that it does not alter testicular secretion of testosterone. To test this assumption, we measured gonadotropin and testosterone levels in seven boys with ALL who had been treated with radiation for clinically apparent testicular relapse. In four of seven boys, testicular relapse was bilateral with overt involvement of one testicle and microscopic involvement of the other. Three of these four boys demonstrated delayed sexual maturation, and in addition to elevated follicle-stimulating hormone (FSH) concentrations, testosterone levels were low and luteinizing hormone levels were elevated compared with controls. These data indicate that boys with overt testicular leukemia who are treated with 2,400-rad testicular radiation are at risk for Leydig cell dysfunction. However, the relative contributions of radiation, prior chemotherapy, and leukemic infiltration to this dysfunction remain to be clarified.

We have examined the hormonal alterations of testicular function in 27 males (14 to 67 years of age) with soft-tissue sarcoma who were treated with surgery and high-dose radiation to the tumor bed. The testicular dose from scatter radiation ranged from 1 to 2,500 rad. There was a dose-dependent increase in the median per patient difference from baseline in serum follicle-stimulating hormone (FSH) values following irradiation, with the maximal difference seen at 6 months. Recovery of serum FSH level was biphasic with a decline in the median difference in values between 6 and 12 months, followed by a gradual descent toward baseline. Only patients receiving less than 50 rad show early complete recovery 12 months after radiation therapy. Radiation injury also induced dose-dependent increases in serum luteinizing hormone (LH) concentration, with the maximal median difference from baseline level occurring at 6 months. Only those patients receiving greater than 200 rad showed statistically significant LH changes from baseline levels at each time interval up to 30 months. No significant changes were observed in total testosterone values. These data provide quantitative guidelines for predicting seminiferous tubule injury and germ cell depletion in men exposed to fractionated radiation. The effects on seminiferous tubule and Leydig cell function, as judged by serum FSH and LH concentrations, suggest that subtle Leydig cell dysfunction, in addition to germ cell depletion, may also occur at exposures greater than 200 rad.

Published: February 2017

After hysterectomy, 156 evaluable patients with stage I (limited to the corpus) or stage II (limited to the corpus and cervix) uterine sarcomas were randomly assigned to adjuvant chemotherapy with Adriamycin (Adria Laboratories, Columbus, Ohio) for six months or to no further treatment. Pelvic irradiation (external or intracavitary) was optional before randomization. Of 75 patients receiving Adriamycin, 31 have suffered recurrences compared with 43 of 81 receiving no adjuvant chemotherapy. This difference is not statistically significant. Moreover, there is no difference in progression-free interval or survival. The optional radiotherapy did not influence the outcome although there was a suggestion that vaginal recurrence was decreased by pelvic radiotherapy. The recurrence rates in specific cell types (leiomyosarcoma, homologous mixed mesodermal sarcoma, or heterologous mixed mesodermal sarcoma) were not significantly different although the pattern of recurrence differed, with pulmonary metastases being more common in leiomyosarcoma and extrapulmonary recurrence being more common in mixed mesodermal sarcoma. The outcome with respect to chemotherapy was not altered even after adjusting for maldistribution of cases. Thus, we could not show a benefit for this dose schedule of Adriamycin as adjuvant treatment for uterine sarcomas.
Altered von Willebrand factor molecule in children with thrombosis following asparaginase-prednisone-vincristine therapy for leukemia.
Authors: Pui C H , Chesney C M , Weed J , Jackson C W
Published: February 2017

Eleven consecutive leukemia patients with thrombosis induced by asparaginase-prednisone-vincristine therapy were studied to gain insight into the pathogenesis of this complication. Measurement of anti-thrombin III, plasminogen, factor V, and fibrin degradation products as well as platelet aggregation sensitivity to adenosine diphosphate disclosed no consistent abnormalities that would explain pathologic thrombus formation. A decrease in platelet counts observed in nine of 11 patients, prompted us to investigate the possible involvement of factor VIII in this disorder. Levels of factor VIII procoagulant activity, von Willebrand factor (vWF) and ristocetin cofactor were similar to findings for an identically treated comparison group who remained free of thrombotic complications. However, qualitative examination of vWF by crossed immunoelectrophoresis (CIE) revealed a distinct right shift of the immunoprecipitin lines in each of three thrombotic patients tested, whereas a normal profile was found in three similarly treated patients without the complication. This altered pattern had reverted to normal when CIE was repeated 2 to 7 months later. We postulate that the abnormal vWF is related to the development of thrombosis.
Reversible increase in serum alpha-fetoprotein content associated with hepatic dysfunction during chemotherapy for seminoma.
Authors: Grem J L , Trump D L
Published: February 2017

Serial monitoring of the serum content of the beta subunit of human chorionic gonadotropin (beta hCG) and alpha-fetoprotein (alpha FP) is useful in the initial staging of germ cell tumors and assessing the response to treatment. An increase in either marker during or following treatment almost always heralds disease progression and indicates the need for additional therapy. We report two patients in whom substantial increases in the serum content of AFP occurred during chemotherapy for advanced seminoma. Hepatic dysfunction was present in both patients; in one patient, a chronic carrier of hepatitis B virus, the liver dysfunction was associated with reactivation of hepatitis B manifested by anicteric hepatitis and hepatitis B e antigen positivity. Marked tumor regression had occurred in both patients, and chemotherapy was discontinued in spite of the elevated alpha FP level. The alpha FP content in the serum gradually returned to normal, and hepatic dysfunction resolved. Both patients remain free of disease 15 and 17 months following the last chemotherapy treatment. These cases illustrate that hepatic dysfunction and alpha FP production may occur during chemotherapy and that increases in serum alpha FP content must be interpreted with caution since the elevated alpha FP level does not always indicate progression of germ cell tumors.

Published: February 2017

A prospective comparative analysis of home and hospital comprehensive treatment for advanced non-ambulatory cancer patients was conducted. Patients were assigned to hospital (group A) and home (group B) treatment groups based on geographic location. Home treatment was provided by the Don Monti Home Oncology Medical Extension (HOME) program. A multidisciplinary health team, including an oncologist, oncology nurse, social worker, dietitian, and medical technologist, was transported to the home in a medically equipped van. Services included physical examinations, pain control, psychosocial interventions, chemotherapy and blood transfusions, nutrition consultation, and bereavement counseling. One hundred seventy-four patients were treated at home and 44 in the hospital. Pretreatment characteristics were similar for both groups, with the exception that age under 50 years was more frequent in the hospital group, and home patients were more likely to have gastrointestinal (GI) cancer. Medical benefits for home treatment included decreased narcotic analgesic requirements, decreased hospitalization and length of stay, and improved measurements of fat stores for female patients. Improved survival for home patients was related to Karnofsky performance status, since there was no difference in survival for sicker patients with lower performance status whether they received home or hospital treatment. Patient and family acceptance of home treatment was excellent. Comprehensive home treatment provided by a multispecialty oncology team is an effective alternative to hospitalization for terminal cancer patients.
Comparison of circulating CA15-3 and carcinoembryonic antigen levels in patients with breast cancer.
Authors: Hayes D F , Zurawski V R , Kufe D W
Published: February 2017

An immunoradiometric assay (IRMA) has been used to determine circulating levels of the breast cancer-associated antigen, CA15-3. Of 1,050 normal control subjects, serum from 99 (9.4%) had CA15-3 antigen levels greater than 22 U/mL, while that from 58 (5.5%) and 14 (1.3%) had levels greater than 25 U/mL and 30 U/mL, respectively. In contrast, 115 of 158 patients (73%) with metastatic breast cancer had CA15-3 levels greater than 22 U/mL. Thirteen of 26 patients (50%) with only local metastases, 27 of 34 (79%) of those with only bone metastases, and 20 of 24 (83%) with hepatic metastases had CA15-3 levels greater than 22 U/mL. Furthermore, nine of 31 patients (29%) with primary breast cancer had CA15-3 levels greater than 22 U/mL. CA15-3 and carcinoembryonic antigen (CEA) levels were compared for the same patient population. Significantly more patients with metastatic breast cancer had elevated CA15-3 levels than had elevated CEA levels (P less than .001). Furthermore, the CA15-3 IRMA was more sensitive than the CEA assay in patients with only bone metastases, as well as those with only local metastases. Significantly more patients with primary carcinoma of the breast also had elevated CA15-3 than had elevated CEA levels (P less than .02). CA15-3 levels were greater than 22 U/mL in patients with nonmalignant conditions, including five of 25 patients (20%) with benign breast diseases, and 23 of 52 patients (44%) with benign liver diseases. Furthermore, CA15-3 levels were also greater than 22 U/mL in 24 of 54 patients (44%) with gastrointestinal (GI) malignancies, 12 of 17 patients (71%) with bronchogenic carcinoma, and 29 of 44 patients (66%) with epithelial ovarian carcinoma. Serial CA15-3 levels correlated with clinical disease course. Nineteen of 21 patients (91%) with tumor progression had at least a 25% increase in CA15-3 levels. Conversely, seven of nine patients (78%) with tumor regression had at least a 50% decrease in CA15-3 levels. Among 27 patients with stable disease, 16 (59%) had levels that did not vary by more than +/- 25% of the original CA15-3 levels. These results indicate that the CA15-3 antigen is a sensitive marker for the evaluation and monitoring of patients with breast cancer.
Effects of brain irradiation and chemotherapy on myelosuppression in small-cell lung cancer.

Published: February 2017

The effect of brain irradiation on myelosuppression was studied in patients with untreated small-cell lung cancer (SCLC) by comparing 24 patients who received brain irradiation for brain metastasis at presentation (irradiated patients) with 24 control patients who were selected by matching ages and non-CNS metastatic sites with those of irradiated patients. All patients were evaluated during the first three courses of chemotherapy. More irradiated patients than control patients had chemotherapy dose reductions from the starting dose level for the second (nine of 22 v two of 24; P = .03) and the third (nine of 18 v three of 20; P = .05) courses of chemotherapy. Overall, more irradiated patients had chemotherapy dose reductions than did control patients (11 of 22 v three of 24; P = .01). The difference was highly significant even after other variables were considered in a multivariate analysis (P less than .001). Myelosuppression was more severe in irradiated patients for WBCs (P = .01) and for platelets (P = .05). When the second course of chemotherapy was administered at the same dose levels as in the first course, irradiated patients had greater decreases in nadir counts after the second course compared with the first course than did control patients. Irradiated patients had a higher incidence of infectious complications than did control patients (14 of 24 v six of 24; P = .02), particularly after the second course of chemotherapy (seven of 22 v one of 24; P = .04). There were four treatment-related deaths due to sepsis in irradiated patients. Following brain irradiation given concurrently with intensive chemotherapy, close monitoring of myelosuppression and adjustments of chemotherapy doses are advised.

Combinations of interferon-alpha and interferon-gamma demonstrate synergistic antiviral and anti-proliferative activity in vitro. Therefore, we initiated a clinical study of combination interferon therapy in humans. Eighteen patients with metastatic solid tumors received daily intramuscular (IM) injections of recombinant interferon-alpha-A (IFN alfa-2a, Roferon-A; Hoffman-LaRoche, Nutley, NJ) and recombinant IFN-gamma (rIFN-gamma) for 6 weeks. The dose levels were 0.5, 1.0, 2.0, and 5.0 X 10(6) U/m2/d of each interferon. A minimum of two patients were entered sequentially at each dose level. Fever, chills, fatigue, and a greater than or equal to 50% drop in granulocyte counts were observed at all doses. Severity of symptoms corresponded to increasing dose levels. In contrast to the tachyphylaxis to these symptoms that usually develops in patients treated with the individual interferons, many patients on this study experienced persistent fever and worsening fatigue over 6 weeks. The maximum tolerated dose was 1 X 10(6) U/m2/d of each interferon. One patient with renal-cell carcinoma achieved a partial remission (duration, 3 months). Enzyme-linked immunoassay analysis in all four patients for whom complete data were available revealed that peak blood levels of IFN alfa-2a on day 22 were about tenfold higher than on day 1. Because of the possibility of cumulative toxicity, the recommended starting dose for further studies is 0.5 X 10(6) U/m2/d of each interferon, with escalation to 1.0 X 10(6) U/m2/d after 1 month if tolerance is acceptable. Phase II investigations to explore the antitumor efficacy of this regimen are planned.
A new endpoint for the assessment of adjuvant therapy in postmenopausal women with operable breast cancer.

Between 1978 and 1981, 463 evaluable postmenopausal patients 65 years of age or younger with operable breast cancer and metastases in axillary lymph nodes were entered in Ludwig Breast Cancer Study III (Ludwig III) and randomly allocated to receive chemoendocrine therapy with cyclophosphamide, methotrexate, 5-fluorouracil, low-dose continuous prednisone, and tamoxifen (CMFp + T) for 12 monthly cycles, or endocrine therapy alone with prednisone and tamoxifen (p + T) for 1 year, or no adjuvant treatment after mastectomy (observation). At 60 months' median follow-up, the 5-year disease-free survival (DFS) rates were 59% for CMFp + T, 41% for p + T, and 31% for observation (P less than .0001), and the 5-year overall survival (OS) rates were 71% for CMFp + T, 64% for p + T, and 59% for observation (P = .16; CMFp + T v observation, P = .07). A new quality of life-oriented endpoint was defined to assist in the selection of therapeutic approach after surgery for postmenopausal patients: the time without symptoms of disease and subjective toxic effects of treatment (TWiST). Despite the larger initial discount due to subjective toxicity with chemoendocrine therapy, by 5 years postmastectomy the net difference in average TWiST for treated patients compared with the observation group was positive and approximately equal for both adjuvant treatment programs. Adjuvant chemoendocrine therapy for postmenopausal women appears to be justified due to an emerging OS advantage and increasing TWiST gained for the treated patients.

In a phase II multicenter trial, 71 patients with advanced measurable gastric cancer were registered to receive sequential high-dose methotrexate (MTX) and 5-fluorouracil (5-FU) combined with Adriamycin (A [Adria Laboratories, Columbus, OH]). The response rate was 33% (22 of 67), including all eligible patients. There were nine complete responders (CRs). The median survival for all patients was 6 months. There has been one toxic death; however, three other patients died from toxicity associated with major protocol violations. It is concluded that this protocol is active in gastric cancer. Toxicity, partly because of nonprotocol adherence, is considerable and is now under further investigation in a randomized trial comparing this schedule with a combination of 5-FU, Adriamycin, and mitomycin C (FAM).
Association of reduced total iron binding capacity and fungal infections in leukemic granulocytopenic patients.
Authors: Karp J E , Merz W G
Published: February 2017

Serum total iron-binding capacity (TIBC) was measured serially on 70 patients with acute leukemia throughout the period of chemotherapy-induced granulocytopenia. Fungal infections were documented in 13 of these patients (18.6%), while 41 patients (58.6%) had clinically suspected fungal infections and 16 (22.9%) had no evidence of fungal infections during the granulocytopenia. Documented fungal infection occurred in patients with the greatest reduction in TIBC (P less than .015). Early reduction in TIBC also correlated with a greater risk for occurrence of fungal infection, and the earliest institution of amphotericin B (Amp-B) (P less than .004). Effective antifungal therapy was further associated with a return of TIBC levels toward normal. These data demonstrate that altered iron metabolism during granulocytopenia is associated with the development of fungal infections in compromised patients. Serial monitoring of TIBC, along with other clinical and mycologic findings, may prove useful in developing strategies for predicting patients at risk for developing a fungal infection and directing the appropriate use of empiric therapy with Amp-B.

Clinical, histologic, and cytogenetic features in 63 patients with a therapy-related myelodysplastic syndrome (t-MDS) or acute nonlymphocytic leukemia (t-ANLL) following cytotoxic chemotherapy or radiotherapy for a previous disease were analyzed. Eleven patients had received only radiotherapy for the primary disorder. In most cases, high doses had been administered to treatment ports that included the pelvic or spinal bone marrow. Twenty-one patients had received only chemotherapy for their primary disease, all for more than 1 year and all but one with an alkylating agent, either alone or in combination with other drugs. Thirty-one patients had received both radiotherapy and chemotherapy, either concurrently or sequentially. A clonal chromosomal abnormality was observed in marrow or blood cells from 61 of the 63 patients (97%). Fifty-five patients (87%) had a clonal abnormality of chromosomes no. 5 and/or 7 consisting of loss of all or part of the long arm of the chromosome. The critical chromosome region that was consistently deleted in all 17 patients with del(5q) comprised bands q23 to q32. In addition to nos. 5 and 7, five other chromosomes (no. 1, 4, 12, 14, and 18) were found to be nonrandomly involved. Both t-MDS and t-ANLL are late complications of cytotoxic therapies that have distinctive clinical and histologic features and are associated with characteristic aberrations of chromosomes no. 5 and 7. It seems likely that these two chromosomes contain genes involved in the pathogenesis of these hematopoietic neoplasms.

One-hundred thirty eligible patients with advanced colorectal carcinoma who had received no prior chemotherapy were randomized to either methyl-CCNU, 70 mg/m2 orally every 6 weeks on day 1, mitomycin C, 10 mg/m2 intravenously every 6 weeks on day 1, and 5-fluorouracil (5-FU), 400 mg/m2 intravenously weekly--(MMF)--or 5-FU, 600 mg/m2 intravenously weekly (5-FU). One hundred twenty-six patients are evaluable for response. Of 62 patients treated with MMF, one (2%) achieved complete remission, and three (5%) attained partial remission. Of 64 patients treated with 5-FU, two (3%) achieved complete remission, and eight (13%) attained partial remission. The median survival for patients receiving MMF was 9.5 months compared with 10.3 months for patients receiving 5-FU. The survival distributions for the two regimens were not significantly different, either unadjusted or adjusted for pretreatment characteristics. Performance status and lactic dehydrogenase (LDH) were both significantly associated with survival. Patients with liver metastases only and normal liver function tests had a median survival of 19.8 months and a 40% response rate. This randomized phase III trial did not show any therapeutic advantage for MMF compared to 5-FU therapy alone in advanced colorectal cancer. In addition, hematologic toxicity was significantly greater with the combination (MMF) regimen.

Published: February 2017

The effect of age as a prognostic factor in recurrent breast cancer was studied in 1,168 patients treated on Eastern Cooperative Oncology Group (ECOG) protocols. Survival was significantly shorter in patients less than 35 years of age (P = .03). This was true even when other good prognostic factors were present. Eighteen prognostic factors were analyzed, and the effect on survival in each of six age groups was studied. Patients with better performance status, less than three sites of metastases, and without visceral or nodal metastases had a better survival time. A Cox proportional hazards model of survival showed that younger age groups, irrespective of menopausal status, had shorter survival times. The predicted median survival times after the first recurrence were 491 days for patients less than 35 years of age, 590 days for patients 36 to 45 years of age, and 700 days for those greater than 45 years of age.

Ninety patients with breast cancer refractory to cyclophosphamide/fluorouracil/methotrexate (CMF) have been randomized in their treatment, receiving either doxorubicin or mitoxantrone. Seventy-nine have received two full courses of therapy. Twelve of the 40 (30%) who initially received doxorubicin responded, whereas eight of the 47 (17%) who received mitoxantrone responded. These rates are not statistically different. The degree of myelosuppression was equivalent. Patients who received mitoxantrone had less nausea, vomiting, alopecia, and fatigue. Controllable clinical congestive heart failure developed in seven patients, and four others had a deterioration of noninvasive measures of cardiac function without clinical failure. One patient with clinical heart failure developing received only doxorubicin and one, only mitoxantrone, whereas the others received both agents. The duration of remission and time lapsed before disease progression were almost identical for the two regimens. This study included a crossover design. Two of 22 (10%) patients receiving doxorubicin and five of 24 (21%) receiving mitoxantrone as secondary therapy responded. This suggests that there is not absolute cross-resistance between these agents. We conclude that the efficacy of these two drugs is comparable in patients refractory to CMF, though the nonhematologic side effects of mitoxantrone are less.

We report the results of an expanded trial of 5-fluorouracil (5-FU) combined with high-dose folinic acid for treatment of patients with advanced colorectal or advanced gastric adenocarcinoma. In each treatment course, the patients received both 5-FU (340 to 400 mg/m2/d by intravenous (IV) infusion for a period of 15 minutes) and folinic acid (200 mg/m2/d by IV bolus) for 5 consecutive days, with a 21-day interval between courses. Eighty-six patients with colorectal carcinoma were evaluated. The combined complete and partial response rates were 39% for 54 patients who did not receive prior chemotherapy and 22% for 32 patients who had previously received chemotherapy. Four patients who were previously resistant to 5-FU attained objective responses. The median time to disease progression for the 28 responders was 10 months. The median survival time of responders was 19.5 months, and the probability of their being alive at 2 years was 40%. Of 27 patients with gastric adenocarcinoma, 13 (48%) responded to therapy. Their median time to disease progression was 5.5 months. The median survival time of responders was 11 months, and their probability of being alive at 15 months was 30%. Toxicity was within acceptable limits. Toxic effects included stomatitis, diarrhea, conjunctivitis, skin rash, and mild myeloid hypoplasia. In a separate study, plasma concentrations of L-folates greater than 10(-5) mol/L were achieved after a rapid single IV injection of 200 mg/m2 of folinic acid. Comparisons of our results with those reported in previous studies on 5-FU administered as a single agent suggest that, in advanced colorectal and gastric adenocarcinoma, folinic acid administered in high doses enhances the effectiveness of 5-FU administered concomitantly. Furthermore, some colorectal tumors that were previously resistant to 5-FU become sensitive to this drug. The survival of the patients who responded to therapy was markedly improved over that observed in reported series of untreated patients with advanced colorectal and gastric adenocarcinomas.
