PURPOSE

CD30 ligand (CD30L), which is expressed on resting B and activated T lymphocytes, can induce cell death in several CD30+ cell lines. Patients with CD30+ tumors (Hodgkin's disease and Ki-1+ non-Hodgkin's lymphoma) frequently have elevated soluble CD30 (sCD30) levels in their serum, which correlates with a poor prognosis. The role of sCD30 in protecting tumor cells from CD30L-mediated cell death and the pattern of CD30L expression on human peripheral-blood lymphocytes (PBLs) of normal donors and patients with CD30+ tumors are investigated.

MATERIALS AND METHODS

CD30L surface protein expression was determined by two-color flow cytometry on PBLs of patients with CD30+ tumors and normal individuals. CD30L levels were determined on subsets of PBLs before and after stimulation with phytohemagglutinin (PHA), anti-CD3 antibody, or CD40L. sCD30 was measured by enzyme-linked immunosorbent assay (ELISA). The apoptotic activity of membrane-bound CD30L was tested in a CD30+ cell line by the annexin V-binding method.

RESULTS

Unstimulated T lymphocytes of normal donors and patients with lymphoma rarely expressed CD30L surface protein, but were able to express it after stimulation with PHA or anti-CD3 antibody. Resting B cells of patients with CD30+ tumors had lower levels of detectable surface CD30L compared with normal donors (mean, 55% and 80.6%, respectively; P = .0008). Patients with high levels of serum sCD30 had lower detectable levels of CD30L on their PBLs (R2 = .72, P = .0008) and exogenous sCD30 blocked membrane-bound CD30L-mediated apoptosis in a CD30+ cell line.

CONCLUSION

In patients with CD30+ tumors, sCD30 can decrease the availability of CD30L on PBLs. Blocking the apoptosis-inducing activity of CD30L by its soluble receptor may explain how CD30+ tumors escape immunosurveillance and may be related to the reported poor prognosis of patients who have elevated sCD30 levels.

Published: February 2017

PURPOSE

Thrombocytopenia may compromise cancer treatment, causing chemotherapy dose reductions, schedule alterations, or the need for platelet transfusions. We evaluated the efficacy and safety of recombinant human interleukin-11 (rhIL-11; Neumega, Genetics Institute, Inc, Cambridge, MA), a novel thrombopoietic growth factor, in reducing the need for platelet transfusions in patients who undergo dose-intensive chemotherapy.

PATIENTS AND METHODS

Women with advanced breast cancer received cyclophosphamide (3,200 mg/m2) and doxorubicin (75 mg/m2) plus granulocyte colony-stimulating factor (G-CSF; 5 microg/kg/d). Patients were randomized to blinded treatment with placebo or 50 microg/kg/d rhIL-11 subcutaneously for 10 or 17 days after the first two chemotherapy cycles.

RESULTS

Seventy-seven patients were randomized and constitute the intent-to-treat (ITT) population. Sixty-seven patients (the assessable subgroup) either completed both cycles without a major protocol violation (n = 62) or received a platelet transfusion before treatment was discontinued after the first cycle. In the ITT population, rhIL-11 significantly decreased the requirement for platelet transfusions; 27 of 40 (68%) patients who received rhIL-11 did not require transfusions, compared with 15 of 37 (41%) in the placebo group (P = .04). Treatment with rhIL-11 significantly reduced the total number of platelet transfusions required in the assessable subgroup (P = .03) and the time to platelet recovery to more than 50,000/microL in the second cycle (P = .01). Most adverse events associated with rhIL-11 were reversible, mild to moderate in severity, and likely related to fluid retention.

CONCLUSION

rhIL-11 is safe and effective in reducing treatment-associated thrombocytopenia and the need for platelet transfusions in patients who undergo dose-intensive chemotherapy, and thus may permit chemotherapy to be administered as planned at intended doses and thereby maximize the potential for a successful outcome.
Randomized trial of chemotherapy and radiation therapy with or without warfarin for limited-stage small-cell lung cancer: a Cancer and Leukemia Group B study.

Published: February 2017

PURPOSE

Studies by the Veterans Administration Cooperative Studies Program and Cancer and Leukemia Group B (CALGB) suggested that the addition of warfarin to chemotherapy might enhance response and/or survival in small-cell lung cancer (SCLC). This randomized study evaluated the effect of warfarin with chemotherapy and radiation therapy in limited-stage SCLC.

PATIENTS AND METHODS

Patients were randomized to receive warfarin or no warfarin. All patients received three cycles of doxorubicin, cyclophosphamide, and etoposide (ACE). Cycles 4 and 5 (cisplatin, cyclophosphamide, and etoposide [PCE]) were given concurrently with radiation therapy. Three cycles of ACE were given after chemoradiation therapy, but were discontinued due to a high rate of pulmonary toxicity.

RESULTS

There were no significant differences in response rates, survival, failure-free survival, disease-free survival, or patterns of relapse between the warfarin-treated and control groups. In patients treated according to the initial design, an increase in failure-free survival seen with warfarin treatment approached significance (P = .07). Preamendment results, while not significant, did not have superimposable treatment survival curves. A landmark analysis at 8 months showed a median survival time after the landmark for complete responders of 33 months with warfarin treatment compared with < or = 13.75 months for complete or partial responders not treated with warfarin (P = .05). Differences between the complete responders in this preamendment population were not significant (P = .103).

CONCLUSION

Warfarin does not appear to improve outcome significantly in limited-stage SCLC. However, the differences in some variables between populations before the protocol amendment correspond to the favorable effects of anticoagulants observed in previous studies.
Serum tissue polypeptide antigen in bladder cancer as a tumor marker: a prospective study.
Authors: Maulard-Durdux C , Toubert M E , Hennequin C , Housset M
Published: February 2017

PURPOSE

Tissue polypeptide antigen (TPA) is a differentiation and proliferation tissue marker of epithelia. Increased serum levels were found in some patients with invasive bladder cancer. We present the results of a prospective study that evaluated the role of serum TPA (S-TPA) in bladder carcinoma.

PATIENTS AND METHODS

The series included 167 patients treated for invasive bladder cancer between 1989 and 1996. S-TPA concentrations were measured by radioimmunoassay before treatment, at the end of treatment, and during follow-up evaluation. The upper normal limit of the test was set at 80 UI/L.

RESULTS

With a specificity of 100%, the diagnostic sensitivity was 46%. Pretherapeutic S-TPA levels were significantly correlated with tumor stage (T2 v T3 and T4; P = .02), with nodal stage (N0 v N1 and N2; P = .00001), and with metastatic stage (M0 v M1; P = 10[-6]), but not with histologic grading (grade 1 and 2 v 3). In the subset of patients with normal pretherapeutic S-TPA levels, 95% had no residual disease at the end of treatment, compared with 53% of patients with initial elevated S-TPA (P = 10[-8]). Among patients who achieved a complete response, 27% experienced a relapse, with an increase of S-TPA in 72% of cases. The mean follow-up time was 20 +/- 17 months. For patients with normal pretherapeutic S-TPA levels, 3-year overall survival and disease-free survival rates were 76% and 67% respectively. These were 46% (P = .001) and 25% (P = 10[-7]), respectively, for patients with high pretherapeutic S-TPA. Multivariate analysis showed that S-TPA was an independent prognostic factor for survival (P = .03).

CONCLUSION

In invasive bladder cancer, S-TPA level is correlated with initial tumor stage. It is a valuable parameter for follow-up evaluation and appears to be a prognostic factor in multivariate analysis.
Chronologic changes in the clinicopathologic findings and survival of gastric cancer patients.
Authors: Kitamura K , Yamaguchi T , Sawai K , Nishida S , Yamamoto K , Okamoto K , Taniguchi H , Hagiwara A , Takahashi T
Published: February 2017

PURPOSE

To determine the chronologic changes in the clinicopathologic features of gastric cancer patients.

PATIENTS AND METHODS

The clinicopathologic findings of 1,795 patients with gastric cancer were examined retrospectively from hospital records obtained between 1969 and 1995. The patients were divided into three generations on the basis of chronologic order. The first generation included patients treated over the period 1969 to 1977; the second generation, 1978 to 1986; and the third generation, 1987 to 1995.

RESULTS

The chronologic changes in the clinicopathologic findings for all gastric cancers included increases in the superficial type based on macroscopic appearance (P < .005), small-sized tumor (P < .025), superficial depth of invasion (P < .005), and earlier histologic stages (P < .005), in addition to a decrease in lymph node metastasis (P < .005). Overall, the postoperative survival rate has improved over time in gastric cancer patients, with 5-year survival rates of 36.0%, 53.3%, and 68.6% in the first, second, and third generations, respectively. In stages 1,2, and 3, the survival rate in the third generation was the highest of the three generations, whereas in stage 4, the survival rate did not differ between the three generations. Patients who underwent a D2 dissection showed a higher survival rate than those with D1 or D3 dissections, but there was no statistical difference in the survival of patients with D1, D2, and D3 dissections when stage 4 patients were excluded.

CONCLUSION

The chronologic changes in gastric cancer patients over the past 27 years have included an increase in the incidence of earlier-staged gastric cancers, which has had a significant impact on the improved postoperative survival rate.
Rapid recovery of spermatogenesis after mitoxantrone, vincristine, vinblastine, and prednisone chemotherapy for Hodgkin's disease.

Published: February 2017

PURPOSE

Because the effects of mitoxantrone on human male fertility were unknown, we determined prospectively the effects of three courses of mitoxantrone (Novantrone), vincristine (Oncovin), vinblastine, prednisone (NOVP) chemotherapy on the potential for fertility of men with Hodgkin's disease (HD).

PATIENTS AND METHODS

Semen analyses were performed on 58 patients with stages I-III HD before, during, and after chemotherapy and after the sperm count recovered from the effects of abdominal radiotherapy that was given after chemotherapy.

RESULTS

Before the initiation of treatment, 84% of the patients were normospermic. Sperm counts declined significantly within 1 month after the start of NOVP chemotherapy. In the month after chemotherapy, 38% of patients were azoospermic, 52% had counts < 1 million/ mL, and 10% had counts between 1 and 3 million/mL. Between 2.6 and 4.5 months after the completion of chemotherapy, sperm counts recovered rapidly to normospermic levels in 63% of patients. In the remaining patients who were followed up for at least 1 year after standard upper abdominal radiotherapy, counts also recovered to normospermic levels.

CONCLUSION

NOVP chemotherapy, like most other regimens, produced marked temporary effects or spermatogenesis. However, sperm production recovered very rapidly, within 3 to 4 months after the end of NOVP chemotherapy. This pattern was caused by killing differentiating spermatogenic cells, but there was little cytotoxicity or inhibition of stem cells from mitoxantrone or the other drugs. After the combination of NOVP plus abdominal radiotherapy, sperm counts and motility were restored in most patients to pretreatment levels, which were compatible with normal fertility.
Value of different modalities of granulocyte-macrophage colony-stimulating factor applied during or after induction therapy of acute myeloid leukemia.

Published: February 2017

PURPOSE

The hematopoietic growth factors (HGFs) introduced into induction chemotherapy (CT) of acute myeloid leukemia (AML) might be of benefit to treatment outcome by at least two mechanisms. HGFs given on days simultaneously with CT might sensitize the leukemic cells and enhance their susceptibility to CT. HGFs applied after CT might hasten hematopoietic recovery and reduce morbidity or mortality.

MATERIALS AND METHODS

We set out to evaluate the use of granulocyte-macrophage colony-stimulating factor (GM-CSF; 5 microg/kg) in a prospective randomized study of factorial design (yes or no GM-CSF during CT, and yes or no GM-CSF after CT) in patients aged 15 to 60 years (mean, 42) with newly diagnosed AML. GM-CSF was applied as follows: during CT only (+/-, n = 64 assessable patients), GM-CSF during and following CT (+/+, n = 66), no GM-CSF (-/-, n = 63), or GM-CSF after CT only (-/+, n = 60).

RESULTS

The complete response (CR) rate was 77%. At a median follow-up time of 42 months, probabilities of overall survival (OS) and disease-free survival (DFS) at 3 years were 38% and 37% in all patients. CR rates, OS, and DFS did not differ between the treatment groups (intention-to-treat analysis). Neutrophil recovery (1.0 x 10(9)/L) and monocyte recovery were significantly faster in patients who received GM-CSF after CT (26 days v 30 days; neutrophils, P < .001; monocytes, P < .005). Platelet regeneration, transfusion requirements, use of antibiotics, frequency of infections, and duration of hospitalization did not vary as a function of any of the therapeutic GM-CSF modalities. More frequent side effects (eg, fever and fluid retention) were noted in GM-CSF-treated patients predominantly related to the use of GM-CSF during CT.

CONCLUSION

Priming of AML cells to the cytotoxic effects of CT by the use of GM-CSF during CT or accelerating myeloid recovery by the use of GM-CSF after CT does not significantly improve treatment outcome of young and middle-aged adults with newly diagnosed AML.
Physician desire for euthanasia and assisted suicide: would physicians practice what they preach?
Authors: Howard O M , Fairclough D L , Daniels E R , Emanuel E J
Published: February 2017

PURPOSE

Euthanasia is a pressing public issue. We sought to assess how frequently physicians could perceive of a desire for euthanasia themselves and whether they would be willing to provide patients the same interventions.

METHODS

We interviewed 355 randomly selected oncologists from the United States and interviewed them about their attitudes and practices related to euthanasia and assisted suicide.

RESULTS

Of the 355 oncologists, 48.1% could imagine a situation in which they might desire euthanasia or assisted suicide for themselves. Oncologists who were Catholic and more religious were significantly less likely to desire these interventions for themselves. Of those oncologists who could imagine a situation in which they might desire euthanasia or assisted suicide for themselves, 85.8% found euthanasia and/or assisted suicide acceptable for their patients. Of the oncologists who could not imagine a situation in which they might desire euthanasia or assisted suicide for themselves, 41.7% still found these interventions ethical for their patients. Only 6.8% of oncologists could imagine a situation in which they might desire euthanasia or assisted suicide for themselves but found these interventions unacceptable for their patients.

CONCLUSION

Almost half of surveyed oncologists could imagine a situation in which they would desire euthanasia or assisted suicide. However, in many cases, this was for nonterminal illness which would be prohibited by proposed laws. When physicians desire euthanasia or assisted suicide for themselves, they are willing to provide these interventions for their patients; therefore, most physicians would practice what they preach. Indeed, when they deviate, oncologists overwhelmingly respect patient autonomy rather than impose their own views on patients.

Published: February 2017

PURPOSE

Recipients of allogeneic bone marrow transplants (BMTs) who have relapsed may attain complete remissions when treated with transfusions of leukocytes obtained from the original bone marrow donor. We performed a retrospective study to characterize better this new treatment modality.

PATIENTS AND METHODS

We surveyed 25 North American BMT programs regarding their use of donor leukocyte infusions (DLI). Detailed forms were used to gather data regarding the original BMT, relapse, DLI, response to DLI, complications of DLI, and long-term follow-up evaluation. Reports of 140 patients were thus available for analysis.

RESULTS

Complete responses were observed in 60% (95% confidence interval [CI], 51.9% to 68.1%) of chronic myelogenous leukemia (CML) patients who received DLI and did not receive pre-DLI chemotherapy; response rates were higher in patients with cytogenetic and chronic-phase relapse (75.7%; 95% CI, 68.2% to 83.2%) than in patients with accelerated-phase (33.3%; 95% CI, 19.7% to 46.9%) or blastic-phase (16.7%; 95% CI, 1.9% to 31.9%) relapse. The actuarial probability of remaining in complete remission at 2 years was 89.6%. Complete remission rates in acute myelogenous leukemia (AML) (n = 39) and acute lymphocytic leukemia (ALL) (n = 11) patients who had not received pre-DLI chemotherapy were 15.4% (95% CI, 9.6% to 21.2%) and 18.2% (95% CI, 6.6% to 29.8%), respectively. Complete remissions were also observed in two of four assessable myeloma patients and two of five assessable myelodysplasia patients. Complications of DLI included acute graft-versus-host disease (GVHD) (60%; 95% CI, 51.4% to 68.6%), chronic GVHD (60.7%; 95% CI, 50.3% to 71.1%), and pancytopenia (18.6%; 95% CI, 12.2% to 25.0%). Pre-DLI characteristics predictive of complete response in CML patients were post-BMT chronic GVHD, pre-DLI disease status of chronic phase, and time interval between BMT to DLI less than 2 years. Acute and chronic GVHD post-DLI were highly correlated with disease response (P < .00001).

CONCLUSION

DLI results in complete remissions in a high percentage of patients with relapsed chronic-phase CML. Complete remissions are observed less frequently in patients with advanced CML and acute leukemia. GVHD and pancytopenia occur commonly; GVHD is highly correlated with response.

Published: February 2017

PURPOSE

To examine the prognostic significance of extramedullary leukemia (EML) at presentation in patients with t(8;21)(q22;q22) karyotype.

PATIENTS AND METHODS

Consecutive patients with t(8;21) treated on Cancer and Leukemia Group B de novo acute myeloid leukemia (AML) treatment studies were examined for the presence of EML (granulocytic sarcoma, subcutaneous nodules, leukemia cutis, or meningeal leukemia) at initial presentation. Clinical features and outcome of t(8;21) patients with and without EML were compared.

RESULTS

Of 84 patients with t(8;21), eight (9.5%) had EML manifesting as granulocytic sarcoma (five paraspinal, one breast, and one subcutaneous) or symptomatic meningeal leukemia (n = 1). The pretreatment prognostic variables of t(8;21) patients with and without EML were similar. The hematologic complete remission (CR) rate for t(8;21) patients with EML was 50% versus 92% for those without EML (P=.006). The median CR duration for EML patients was 14.7 months. Patients with EML had a shorter survival (P = 0.002, median 5.4 months versus 59.5 months). This poor outcome may relate to inadequate local (radiation or intrathecal) therapy for patients with spinal or meningeal EML, resulting in residual/recurrent EML following induction chemotherapy (n = 2) or at relapse (n = 1) and permanent neurologic deficits (n = 4). Only one of the EML patients received high-dose cytarabine (HDAC) intensification; this is the only EML patient remaining alive in CR.

CONCLUSION

Patients with t(8;21) and EML have a low CR rate and overall survival. An aggressive local and systemic induction therapy should be considered for this patient subset. The effectiveness of HDAC intensification in t(8;21) patients with EML is uncertain and warrants further study.

Published: February 2017

PURPOSE

To investigate the value of intensive consolidation chemotherapy not followed by maintenance therapy in adult acute lymphoblastic leukemia (ALL).

MATERIALS AND METHODS

A multicenter phase II trial was conducted in 130 adult patients with ALL between 16 and 60 years of age. After standard induction therapy, postinduction chemotherapy was given: three courses of high-dose cytarabine (2,000 mg/m2 every 12 hours for four doses) in combination with amsacrine (course one), mitoxantrone (course two), and etoposide (course three). CNS prophylaxis consisted of 10 injections of intrathecal methotrexate (IT MTX). Patients younger than 50 years with an HLA-identical sibling were eligible to receive allogeneic bone marrow transplantation (BMT).

RESULTS

Ninety-five patients (73%) achieved complete remission (CR); 82% were younger than 50 years and 41% were older than 50 years. Seventeen patients (13%) were resistant to chemotherapy, and 18 (14%) died during induction treatment. Only age and performance status were significantly associated with response (P<.001 and .03, respectively). Death during consolidation occurred in four patients. The estimated 5-year overall survival (OS) was 22% for the entire group and 26% for patients younger than 35 years. Disease-free survival (DFS) at 5 years was 28% +/- 6 for patients younger than 35 years, 25% +/- 9 for patients between 35 and 50 years, and 0% for patients older than 50 years. Increasing age (P<.01) and expression of CD34 (P<.01) were adverse factors. Only three patients (3%) developed an isolated CNS relapse.

CONCLUSION

Intensive consolidation including high-dose cytarabine not followed by maintenance therapy provides an outcome for adult patients with ALL that may be worse or even inferior compared with studies using long-term maintenance therapy. High-dose cytarabine in combination with IT MTX was effective for CNS prophylaxis.

Published: February 2017

PURPOSE

In our previous study with MACOPB, we identified a high-risk group of patients with a poor 3-year survival rate of 29%. These patients were defined as having at diagnosis advanced-stage disease with high tumor burden (TB) and elevated lactate dehydrogenase (LDH) level or bone marrow (BM) involvement. A novel therapeutic scheme was investigated to improve the outcome of these patients.

PATIENTS AND METHODS

Fifty patients with high-risk diffuse large-cell lymphoma (DLCL) were enrolled. The therapeutic scheme includes three phases: induction with 8 weeks of MACOPB; intensification with a 3-day course of mitoxantrone 8 mg/m2 plus high-dose cytarabine (HDARA-C) 2 g/m2 every 12 hours plus dexamethasone 4 mg/m2 every 12 hours (MAD protocol) and granulocyte colony-stimulating factor (G-CSF) 5 microg/kg on days 4 to 17 to harvest peripheral-blood progenitor cells (PBPC); consolidation with carmustine (BCNU), etoposide, ARA-C, and melphalan (BEAM) regimen; plus autologous stem-cell transplantation (ASCT) with PBPC, marrow, or both.

RESULTS

Thirty-six patients (72%) achieved a complete response (CR), 11 (22%) showed no response (NR), and three (6%) died of toxicity. Among the 22 PRs or NRs after the induction phase, 56% of patients achieved a CR with subsequent intensified therapy. With a median follow-up duration of 32 months, the overall survival and failure-free survival rates were 56% and 50%, respectively. The disease-free survival rate is 69% at 32 months. Leukapheresis after MAD and G-CSF yielded a median of 32 x 10(6)/kg CD34+ cells and 80 x 10(4)/kg granulocyte-macrophage colony-forming units (CFU-GM). Thirty-nine patients were autografted and 11 did not undergo ASCT: six because of disease progression, four due to toxicity, and one because of patient refusal. The median times to achieve engrafment were 11 days (range, 7 to 19) to a neutrophil count greater than 0.5 x 10(9)/L and 12 days (range, 8 to 60) to a platelet count greater than 50 x 10(9)/L.

CONCLUSION

This sequential scheme with intensified and high-dose chemotherapy with ASCT is feasible with moderate toxicity and may improve the outcome in high-risk DLCL.
Ewing's sarcoma of soft tissues in childhood: a report from the Intergroup Rhabdomyosarcoma Study, 1972 to 1991.
Authors: Raney R B , Asmar L , Newton W A , Bagwell C , Breneman J C , Crist W , Gehan E A , Webber B , Wharam M , Wiener E S , Anderson J R , Maurer H M
Published: February 2017

PURPOSE

One hundred thirty of 2,792 patients (5%) registered on three Intergroup Rhabdomyosarcoma Study clinical trials (IRS-I, -II, and -III) from 1972 to 1991 had an extraosseous Ewing's sarcoma (EOE). We report here the results of multimodality therapy for this tumor.

PATIENTS AND METHODS

The 130 patients were less than 21 years of age; 70 (54%) were males. Primary tumor sites were on the trunk in 41 patients, an extremity in 34, the head/neck in 23, the retroperitoneum/pelvis in 21, and other sites in 11. One hundred fourteen patients had no metastases at diagnosis. In 21 patients, the tumor was completely resected; in 30, the localized or regional tumor was grossly resected, and in 63 patients, grossly visible sarcoma was left behind. Sixteen patients (12%) had distant metastases at diagnosis. All patients were given multiagent chemotherapy and most received irradiation (XRT); none were treated with bone marrow transplantation.

RESULTS

One hundred seven patients (82%) achieved a complete response. At 10 years, 62%, 61%, and 77% of the patients were alive after treatment on IRS-I, IRS-II, or IRS-III therapeutic protocols, respectively, similar to figures obtained in all IRS patients. At last follow-up evaluation, 42 patients had died of progressive tumor and one of infection. Survival at 10 years was most likely for patients with tumor that arose in the head and neck, extremities, and trunk, and for those who underwent grossly complete tumor removal before initiation of chemotherapy. For patients with localized, gross residual tumor, adding doxorubicin (DOX) to the combination of vincristine, dactinomycin, cyclophosphamide (VAC), and XRT did not significantly improve survival in 39 patients (62% alive at 10 years) compared with that of 24 patients treated with VAC and XRT without DOX (65% alive at 10 years, P = .93).

CONCLUSION

This series indicated that EOE in children is similar to rhabdomyosarcoma (RMS) in its response to multimodal treatment. No benefit was apparent from the addition of DOX to VAC chemotherapy in patients with gross residual EOE.
Phase II study of irinotecan in prior chemotherapy-treated squamous cell carcinoma of the cervix.

Published: February 2017

PURPOSE

A phase II study was performed to evaluate the antitumor activity and toxicity of irinotecan (CPT-11), a water-soluble derivative of camptothecin, in patients with prior chemotherapy-treated squamous cell cancer of the cervix.

PATIENTS AND METHODS

Forty-two patients were included in the study. The median age was 44 years (range, 24 to 59 years). The median Zubrod performance status was 1. All patients were refractory to first-line chemotherapy and 88% had received prior radiotherapy. The initial dose of CPT-11 was 125 mg/m2 given as a weekly 90-minute intravenous infusion for 4 weeks, every 6 weeks. Subsequent doses were unchanged, reduced, or omitted according to toxicity grade.

RESULTS

Forty-two patients were assessable for response. The overall response rate was 21%. The median time to response was 6 weeks and the median duration of response was 12 weeks. The overall median duration of survival was 6.4 months. A statistically significant survival advantage (median of 12.6 v 5.1 months) was found in patients whose disease responded to the treatment (P < .015). The major dose-limiting toxic effects (grade > or = 3) were nausea and vomiting (45%), diarrhea (24%), and granulocytopenia (36%). Grade > or = 3 anemia was encountered in 62% of patients and the incidence of thrombocytopenia was negligible. Less severe side effects were alopecia (48%), drug fever (43%), anorexia (33%), fatigue (33%), skin rash (21%), stomatitis (14%), and allergic reaction (9%). The gastrointestinal intolerance was dose-related. The incidence of bone marrow depression did not decrease with dose reduction, possibly because of a cumulative effect or hematologic intolerance by a subset of patients.

CONCLUSIONS

CPT-11 has significant activity in refractory cervical carcinoma. Gastrointestinal intolerance and hematologic toxicity must be monitored carefully. Further studies of alternative schedules may improve the tolerance and response rate.

PURPOSE

To determine the feasibility and toxicity of inducing autologous graft-versus-host disease (GVHD) with cyclosporine in patients with multiple myeloma undergoing autologous stem-cell transplantation.

PATIENTS AND METHODS

Fourteen multiple myeloma patients with a median age of 50 years (range, 41 to 63) were enrolled. The median time from diagnosis to transplant was 651 days (range, 229 to 3,353). Ten patients had primary refractory disease, two were in first remission, and two were responsive to salvage therapy. The preparative regimen consisted of thiotepa, busulfan, and cyclophosphamide. Cyclosporine was administered daily for 28 days after the stem-cell infusion, and the dose was adjusted to maintain whole-blood cyclosporine levels between 50 and 150 ng/dL in the first seven patients (low-level group) and between 150 and 300 ng/dL in the other seven patients (high-level group).

RESULTS

All patients achieved neutrophil engraftment a median of 11 days after transplant. Four patients developed > or = grade 2 hepatic toxicity, six developed > or = grade 2 nephrotoxicity, and four developed reversible cardiac toxicity. Only one treatment-related death occurred. Cyclosporine was withheld in seven patients for a median of 6 days because of renal and/or liver dysfunction. One patient developed clinical skin GVHD, which responded to corticosteroid therapy. Six patients developed histologic evidence of GVHD without clinical signs of GVHD (subclinical GVHD). The incidence of clinical and subclinical GVHD was similar in both cyclosporine groups. Three of 11 patients assessable for response achieved remissions. Three patients experienced disease progression 80, 160, and 354 days after transplant. Ten patients are alive without progression between 56 and 444 days after transplant.

CONCLUSION

Induction of autologous GVHD by posttransplant cyclosporine is feasible and well tolerated in patients with multiple myeloma.

PURPOSE

To conduct a multicenter phase II study of a concomitant combination of chemotherapy and radiotherapy followed by surgery, where feasible, in patients with nonmetastatic esophageal tumor, stratified on operability at diagnosis.

METHODS

Each cycle consisted of fluorouracil (5FU) 800 mg/m2/d by continuous intravenous (IV) infusion on days 1 to 5, cisplatin (CDDP) 50 mg/m2/d IV bolus on days 1 and 8, hydroxyurea (HU) 1.5 or 2 g/d orally on days 8 to 12 and concomitant radiotherapy 20 Gy in 10 fractions over 12 days. All patients were to receive two cycles on days 1 and 22. If feasible, surgery was performed 3 to 6 weeks after cycle two completion. Otherwise, a third cycle was administered.

RESULTS

Eighty-eight patients were included between September 1990 and September 1993. Of the 47 operable patients, 41 (87%) underwent surgery and 38 (81%) had a complete resection. No residual primary tumor was found in the surgical specimen in 17 cases (36%), and only microscopic foci in 13 (28%). Two-year overall and disease-free survival probabilities were 51% (95% confidence interval [CI]; 37 to 65) and 43% (95% CI, 28 to 57), respectively. Among the 41 inoperable patients, 12 (29%) became operable. Seven (17%) had complete resection, two incomplete resection, and three exploratory surgery. Two-year overall and disease-free survival probabilities were 29% (95% CI, 15 to 43) and 27% (95% CI, 13 to 40), respectively. Five deaths occurred during chemoradiotherapy, six postoperatively and four in patients with evidence of cancer. Five late complications (one myelopathy) were observed.

CONCLUSION

Despite a high histologic response rate in initially operable patients, overall survival was similar to that observed in other preoperative chemoradiation series because of substantial toxicity.
Weekly gemcitabine with monthly cisplatin: effective chemotherapy for advanced non-small-cell lung cancer.
Authors: Abratt R P , Bezwoda W R , Goedhals L , Hacking D J
Published: February 2017

PURPOSE

The aim of this study was to examine the efficacy of a regimen of initial gemcitabine followed by cisplatin in patients with advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

Fifty-three patients (36 men and 17 women; age range, 35 to 74 years) were enrolled. Patients had bidimensionally measurable disease. Gemcitabine (phase-specific agent) was administered on days 1, 8, and 15 at a dose of 1,000 mg/m2. Cisplatin (cycle-specific agent) was administered on day 15 (100 mg/m2). Chemotherapy was administered in 28-day cycles.

RESULTS

Of 53 patients enrolled, 50 were assessable for response. The overall response rate was 52%. There were two complete responses (4%) and 24 partial responses (48%). The median survival duration was 13 months and the 1-year survival rate was 61%. The regimen was generally well tolerated. World Health Organization (WHO) grade 3 and 4 neutropenia occurred in 38.8% and 19.2% of patients, respectively. Grade 3 and 4 thrombocytopenia occurred in 13.3% and 7.7% of patients, respectively. Most patients experienced mild nausea and vomiting. Few patients had hair loss and oral toxicity was mild. Relatively few patients required dose modifications for any of the three weekly doses of chemotherapy. For the first two cycles of chemotherapy, the dose-intensity per infusion was 947 mg/m2 for gemcitabine and 85 mg/m2 for cisplatin.

CONCLUSION

This regimen of gemcitabine and cisplatin was effective, with high response and survival rates and few dosage modifications during its administration. Prospective randomized studies with other cisplatin-based combination chemotherapy regimens are indicated.

Published: February 2017

PURPOSE

We conducted a phase I trial of carboxyamidotriazole (CAI, NSC 609974), designed to determine the maximum-tolerated dose (MTD), toxicity profile, and pharmacokinetic characteristics of CAI gelatin capsule (gelcap) formulation administered daily as a single oral dose.

PATIENTS AND METHODS

Twenty-nine patients with advanced malignancy who met standard eligibility criteria were treated with once-daily CAI given in cycles of 28 days. Pharmacokinetic sampling was performed on days 1 and 29 and trough plasma CAI levels were assessed weekly.

RESULTS

Patients were entered at dose levels of 50, 75, and 100 mg/m2. All three patients at the 100-mg/m2 level experienced dose-limiting neurocerebellar toxicity. Other neurotoxicities were mild. Gastrointestinal side effects were common, but generally mild, with 23 patients experiencing nausea and/or vomiting of any grade. Fatigue was a frequent complaint, with 19 patients experiencing mild to moderate symptoms. Six patients with nausea and vomiting and five with fatigue experienced relief of symptoms with a change to nocturnal administration of CAI. Peak plasma concentrations (Cp) occurred at 2.4 +/- 1.5 hours after administration of the oral gelcap dose. Patients approached steady-state trough plasma concentrations (Css) by days 8 to 15 and maintained a relatively constant Css throughout the course of treatment. For all patients, the mean variation in weekly CAI Cp was 12.4% +/- 5.3%.

CONCLUSION

The MTD for the gelcap formulation was 75 mg/m2 with dose-limiting neurocerebellar toxicity (ataxia) seen at 100 mg/m2. Other prominent side effects, including nausea, vomiting, and fatigue, were partially alleviated through altering the administration schedule to nighttime dosing.

Published: February 2017

PURPOSE

The prognostic value of the altered expression of carbohydrate antigens sialyl Le(a) (sLe(a)) and sialyl Le(x) (sLe(x)), which have been implicated as functional ligands in heterotypic-cell-adhesion systems in the multistep process of tumor metastasis, were evaluated.

PATIENTS AND METHODS

The level of expression of sLe(a) and sLe(x) antigens was examined immunohistochemically in paraffin-embedded tumor samples from 137 patients who underwent resection for gastric cancer. Correlation between the antigens' expression, various established clinicopathologic factors, and prognosis were studied by univariate and multivariate analysis.

RESULTS

Tumors that were positive for the sLe(a) antigen were significantly more likely to be large (P = .035), to be localized at the proximal third of the stomach (P = .018), to have an infiltrate appearance (P = .013), to have an invasive mode both in depth of invasion (P = .028) and in lymphatic invasion (P = .002), and to be classified as late stage (P = .011) than those that were negative for sLe(a), whereas the sLe(x) antigen status was not correlated with any clinicopathologic factors. The overall survival of patients with an sLe(a)-antigen-positive tumor was significantly poorer than that of those with an sLe(a)-antigen-negative tumor (P = .0001). Survival within each pathologic stage differed also (stage I, P = .030; stage II, P = .046; stage III, P = .026, respectively). A Cox regression analysis with multiple covariates showed that positive sLe(a) antigen status was an independent prognostic factor for a worse outcome in patients with gastric cancer. According to the mode of recurrence, increased sLe(a) antigen expression significantly affected both peritoneal dissemination and liver metastasis.

CONCLUSION

Increased expression of the sLe(a) antigen may serve as a potent prognostic indicator for recurrence in patients with gastric cancer. Careful follow-up and intensive therapy are required for patients with an sLe(a)-antigen-positive gastric cancer.
Clinical potential of new antiestrogens.
Authors: Gradishar W J , Jordan V C
Published: February 2017

PURPOSE

Based on the data and clinical experience derived from tamoxifen usage, the properties of an ideal antiestrogen is described that could have applications as a breast cancer preventative agent, long-term adjuvant therdpy, or as a treatment for osteoporosis. Each of the new antiestrogens currently being tested is discussed in terms of laboratory development, toxicology, pharmacology, endocrinology, and clinical evaluation. And each new compound is assessed according to the properties of an ideal antiestrogen.

METHODS

A review of all published reports was facilitated by the use of Medline computer searches.

RESULTS

Numerous compounds are being evaluated in clinical trials and can be categorized as triphenylethylenes or tamoxifen analogs, pure antiestrogens, and targeted antiestrogens. Several of these compounds may have fewer uterotropic properties and greater effects on maintaining bone density compared with tamoxifen; however, the clinical experience (ie, patient-years of treatment) with any of these compounds is minimal.

CONCLUSION

Although many of these compounds appear promising, further evaluation will be necessary to determine the role these compounds may serve as preventive agents, adjuvant therapies, treatments for advanced disease, or other medical indications such as osteoporosis.

The abstract of the report by Al-Sarraf, et al, entitled, "Progress Report of Combined Chemoradiotherapy Versus Radiotherapy Alone in Patients With Esophageal Cancer: An Intergroup Study" published in the January 1997 issue (J Clin Oncol 15:277–284, 1997) requires a clarification. As was correctly stated on p. 278, the second sentence of the abstract under Materials and Methods should have read: "CT consisted of cisplatin 75 mg/m2 on day 1 and fluorouracil (5FU) 1,000 mg/m2/d on days 1 to 4 every 4 weeks with RT and every 3 weeks post-RT."
Resource implications of palliative chemotherapy for ovarian cancer.
Authors: Doyle C , Stockler M , Pintilie M , Panesar P , Warde P , Sturgeon J , Oza A M
Published: February 2017

PURPOSE

To describe the costs and outcomes of palliative chemotherapy in women with recurrent and refractory ovarian cancer from the perspective of a health care provider.

PATIENTS AND METHODS

A retrospective study of 40 consecutive women who started second- or third-line chemotherapy for recurrent or refractory ovarian cancer between 1989 and 1992. Resource utilization from the commencement of second- or third-line chemotherapy until death or last follow-up evaluation was determined from a detailed chart review. All elements of care were recorded, including inpatient admissions, outpatient visits, chemotherapy drugs, nonchemotherapy drugs, radiation therapy, surgical procedures, investigations, and home care. Costs calculated using the hotel-approximation method are expressed in 1994 Canadian dollars. Actuarial estimates of cost and survival were used to account for censored observations.

RESULTS

After a minimum follow-up period of 24 months, 36 of 40 women had died. The median survival duration of the group was 1.1 years from study entry and 1.7 years from first relapse. The women received a median of two regimens of chemotherapy (range, one to four) from study entry. They spent a median of 33 days as hospital inpatients (mean, 46; range, 0 to 185); 58% of these inpatient days were for symptomatic management and 32% were for chemotherapy. The mean cost per patient was $53,000 (median, $36,600; range, $4,800 to $162,900). The relationship between cost and survival duration was not linear--the cost per year was lowest for those who lived longest. Inpatient admissions, chemotherapy drugs, and outpatient visits accounted for 62%, 21%, and 8% of the total cost, respectively. The total costs attributable to chemotherapy were $24,000 (45% of total costs) and the total costs attributable to supportive care were $23,000 (43% of total costs).

CONCLUSION

These data illustrate the cost of palliative management of recurrent and refractory ovarian cancer, which must be considered in the context of quality and duration of survival. They indicate the potential to improve cost efficiency by improving resource management, for example, by shifting from inpatient to outpatient chemotherapy, everything else being equal.
