PURPOSE Because of the scarcity of information regarding long-term follow-up of pulmonary function after whole-lung irradiation, a prospective study was started at the University of Florida in 1979 to evaluate pulmonary function after treatment with whole-lung irradiation and doxorubicin in patients with osteogenic sarcoma. PATIENTS AND METHODS Between 1979 and 1984, 57 osteogenic sarcoma patients with no evidence of metastatic disease at diagnosis received adjuvant therapy consisting of whole-lung irradiation (with the heart shielded) followed by Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH). The whole-lung irradiation schema was 1,600 cGy in 10 fractions with 8-MV x-rays via anterior and posterior fields. This was followed by five cycles of Adriamycin for a total dose of 450 mg/m2. Pulmonary function tests (PFTs) consisting of spirometry, lung volumes, and diffusing capacity were obtained before the whole-lung irradiation, at 6 and 12 months after irradiation, and at yearly intervals thereafter. RESULTS At the time of analysis, 28 of the 57 patients were available for study, with a mean follow-up of 42 months (range, 6 to 77 months). Follow-up pulmonary function testing revealed decreased forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) during the first 6 to 12 months after whole-lung irradiation. These values returned to baseline during the second-year posttherapy and remained at baseline throughout the remainder of the follow-up period. Changes in lung volumes demonstrated a similar early trend, with significant decreases in total lung capacity (TLC) and functional residual capacity (FRC) at 6 to 12 months. These changes, however, did not improve significantly during the remainder of the follow-up period. Diffusing capacity of the lungs for carbon monoxide (DLCO) also reached a nadir at 6 to 12 months after whole-lung irradiation, with resolution by 2 years and maintenance of at least baseline values for the remainder of the follow-up period. CONCLUSIONS Treatment with whole-lung irradiation and Adriamycin, as given in this study, caused no significant sequelae, as demonstrated by pulmonary function testing during the mean follow-up period of 42 months, although a mild, transient restrictive ventilatory defect occurred at 6 to 12 months after treatment.

PURPOSE The Pediatric Oncology Group (POG) designed a randomized two-arm protocol (8304) to improve the survival of children with acute lymphoblastic leukemia (ALL) who experience an isolated testicular relapse and to evaluate the efficacy of teniposide (VM-26) and doxorubicin as intensification agents during second remission. The outcome and toxicity observed in 80 patients with isolated testicular leukemia treated on POG 8304 are presented. PATIENTS AND METHODS The following are common features of POG 8304: (1) remission reinduction therapy with vincristine, prednisone, and doxorubicin; (2) bilateral testicular irradiation (2,600 cGy) during reinduction therapy; (3) CNS prophylaxis with intrathecal hydrocortisone, methotrexate (MTX), and cytarabine (Ara-C); and (4) continuation therapy (for 80 weeks) with alternating 6-week cycles of oral mercaptopurine (6-MP)/MTX and intravenous vincristine and cyclophosphamide. Treatment differences consisted of pulses (administered every 7 weeks) of either prednisone and doxorubicin (arm 1) or VM-26 and Ara-C (arm 2) during continuation therapy and a 4-week late intensification phase with either vincristine, prednisone, and doxorubicin (arm 1) or VM-26 and Ara-C (arm 2). RESULTS Fifty-five boys with ALL had isolated microscopic testicular leukemia detected by an elective biopsy at completion of initial treatment, and 25 had a late (greater than or equal to 6 months off-therapy) isolated overt testicular relapse. All patients with overt testicular leukemia attained a second clinical remission, and no patient with microscopic testicular leukemia progressed during reinduction. Of 42 patients on arm 1, 11 have relapsed compared with 18 of 38 patients on arm 2 (log-rank analysis, P = .22), indicating no significant difference between an anthracycline and an epipodophyllotoxin-Ara-C combination in the treatment of testicular leukemia. The overall 4-year event-free survival (EFS) among boys with occult testicular relapse was 53% +/- 8%. Age greater than 10 years at initial diagnosis, a WBC count greater than 50,000/microL at diagnosis, and black race were associated with a worse outcome. The 4-year EFS for boys with a late overt testicular relapse was 84% +/- 10%, and these patients fared significantly better than patients with occult disease (P = .007). CONCLUSION The treatment approach reported here can secure a prolonged second remission in many patients with occult or late overt testicular leukemia.
High-dose chemotherapy with autologous bone marrow transplantation for the treatment of metastatic breast cancer.
Authors: Eddy D M 
Published: February 2017

PURPOSE This review was undertaken to examine the evidence of effectiveness of high-dose chemotherapy and autologous bone marrow transplantation (HDC/ABMT) for the treatment of metastatic breast cancer and to compare the magnitudes of the benefits and harms of HDC/ABMT with those of conventional doses of chemotherapy. DESIGN Published studies were reviewed and analyzed. RESULTS No randomized controlled trials have been published that evaluate HDC/ABMT. Only one internally controlled study has been conducted; it demonstrated that HDC/ABMT and conventional treatment have virtually identical outcomes. Comparisons of uncontrolled clinical series are confounded by patient selection and other biases. Gross comparisons indicate that, compared with conventional-dose chemotherapy, HDC/ABMT achieves (1) higher complete response rates (36% v 8%), (2) higher overall response rates (70% v 39%), (3) similar median response durations (8 months v 9.6 months), (4) similar median survival durations (16 months v 16.6 months), and (5) similar overall survival rates (eg, 43% 2-year survival v 39%). Observations of cases with longer-term disease-free survival are promising but not conclusive. High-dose chemotherapy with ABMT has a higher treatment-related mortality rate (5% to 15% v 1%), a high rate of nonmortal toxicity (approximately 30%), and a high rate of side effects (approaching 100%). CONCLUSIONS Firm conclusions are not possible because of the lack of controlled studies and the presence of numerous biases. However, the existing evidence does not demonstrate that HDC/ABMT is superior to conventional-dose chemotherapy for the treatment of metastatic breast cancer. Randomized controlled trials are needed.

PURPOSE The study was designed to determine whether in vivo interferon gamma (IFN-gamma) administration could enhance tumor antigen expression on the surface of human tumor cells. MATERIALS AND METHODS Eight patients (six with ovarian and two with gastrointestinal tumors) with a diagnosis of adenocarcinoma with secondary malignant ascites were given weekly escalating doses of IFN-gamma (ie, 0.1 to 100 MU) intraperitoneally (IP) each week for 8 weeks. Tumor cells were isolated from the patients' ascites samples, which were collected three times per week: before and 24 and 48 hours post-IFN-gamma administration. The level of expression of tumor-associated glycoprotein-72 (TAG-72) and carcinoembryonic antigen (CEA) was measured using flow cytometry and immunocytochemistry. RESULTS IFN-gamma administered IP dramatically increased TAG-72 (as measured by binding of anti-TAG-72 monoclonal antibodies [MoAbs] B72.3 and CC 49) and CEA (measured by MoAb COL-1) expression on the surface of the carcinoma cells. The ascites-derived tumor cells from seven of the eight patients constitutively expressed TAG-72, and the level of TAG-72 expression was increased by IFN-gamma in all seven patients, as evidenced by the enhanced binding of anti-TAG-72 MoAbs to the tumor-cell surface. In some cases, IFN-gamma treatment increased the percentage of MoAb B72.3-reactive tumor cells from 10% to greater than 90%, and those changes were further corroborated by similar increases in the MoAb staining intensity observed with immunoperoxidase analysis. In addition, ascites-derived tumor cells from two patients with gastrointestinal carcinoma also expressed enhanced CEA levels after IFN-gamma. The increased TAG-72 and CEA expression were observed at low IFN-gamma doses (ie, 0.1 to 1.0 MU), which were well tolerated by all patients. CONCLUSIONS The ability of IFN-gamma given IP to increase TAG-72 and CEA expression on tumor cells in vivo provides additional argument for the use of the cytokine as an adjuvant to enhance MoAb binding to human carcinoma-cell populations.

PURPOSE Long-term adverse neurobehavioral sequelae frequently are observed in pediatric patients treated for acute lymphoblastic leukemia (ALL). To clarify the relative contribution of cranial irradiation (CRT) therapy and drug therapy to these outcomes, we evaluated neuropsychologic outcomes associated with different doses of CRT and intravenous (IV) methotrexate (MTX) in long-term survivors. PATIENTS AND METHODS Fifty-one patients treated for ALL on Dana-Farber Cancer Institute protocol 81-01 were evaluated by standardized cognitive and academic achievement tests. These children had been assigned at diagnosis to a standard-risk (SR) or high-risk (HR) group and received 1,800 cGy or 2,800 cGy CRT, respectively. A subgroup of these patients was randomized to receive MTX during remission induction, either as a single low dose (LD; 40 mg/m2) or a single high dose (HD; 4 g/m2) with leucovorin rescue. RESULTS Sex and MTX randomization jointly predicted the intelligence quotient (IQ). Fifty percent of girls versus 14% of boys exhibited low IQ (less than 90; P = .01); 80% of girls who received HD MTX versus 25% of girls who received LD MTX exhibited low IQ (P = .03). In contrast, risk group better predicted performance on tasks sensitive to verbal memory and/or coding. CONCLUSIONS We conclude that (1) significant neurotoxicity occurred principally in girls; (2) increased dose intensity of IV MTX was associated with lower IQ, but only in girls; and (3) increased dose of CRT may have been associated with impairment of verbal memory and coding.

PURPOSE The antineoplastic activity of carboplatin and etoposide may be improved by the addition of vincristine (CEV) because of its low myelosuppressive potential and its activity in small-cell lung cancer (SCLC). A phase II study with CEV was carried out. PATIENTS AND METHODS One hundred twenty-one untreated patients with SCLC (63 with limited disease [LD], 58 with extensive disease [ED]) were treated with a combination of 300 mg/m2 intravenous (IV) on day 1, etoposide 140 mg/m2 IV daily on days 1 to 3, and vincristine 1.4 mg/m2 IV on days 1, 8, and 15 every 4 weeks. RESULTS A 90% rate overall response rate including 56% complete responses (CRs) was achieved in LD and an 83% overall response rate including 35% CRs was observed in ED. Median survival time was 13 months in limited disease and 9.5 months in extensive disease. The 24 and 36 months survival rates were 29% in LD and 9% in ED. Myelosuppression was the main form of toxicity. CONCLUSION The combination of CEV is a new active and well-tolerated regimen in the treatment of SCLC. Prospective randomized studies of CEV with conventional chemotherapy are warranted.

PURPOSE We analyzed pretreatment characteristics of patients with postremission acute myeloid leukemia (AML) treated with high-dose cytarabine (HIDAC) during a recent Cancer and Leukemia Group B (CALGB) trial to determine risk factors associated with HIDAC neurotoxicity. PATIENTS AND METHODS One hundred seventy-six patients received at least one course of HIDAC as part of a CALGB protocol designed to determine the optimal dose of cytarabine (ara-C) for postremission treatment of AML. HIDAC consisted of 3 g/m2 ara-C infused over 3 hours at 12-hour intervals on days 1, 3, and 5. The pretreatment characteristics of 170 patients were available for risk analyses. RESULTS Eighteen patients (10%) experienced neurotoxicity. Univariate analyses demonstrated associations between the occurrence of neurotoxicity and elevated serum creatinine, age, and alkaline phosphatase (AP). Multivariate analysis showed that these variables were independent risk factors. These findings were used to construct a risk model with the following parameters: creatinine greater than or equal to 1.2 mg/dL, age greater than or equal to 40 years, and AP greater than or equal to 3 x normal. Seventeen of 46 (37%) patients with two or more of these criteria developed neurotoxicity compared with one of 124 (1%) patients with one or none. The sensitivity and specificity of this model were 94% and 81%, respectively. CONCLUSION We conclude that patients with two or more of the following parameters may be at increased risk for HIDAC neurotoxicity: (creatinine greater than or equal to 1.2 mg/dL, age greater than or equal to 40, and AP greater than or equal to 3 x normal). However, this model should be confirmed by analysis of additional groups of patients treated with HIDAC.

PURPOSE For patients with Hodgkin's disease (HD) who do not achieve complete response (CR), who experience a relapse within the first year of CR, and for those who have two or more relapses, the outcome is poor. Salvage chemotherapy regimens at conventional doses produce a CR rate that ranges from 10% to 50% and a 5-year disease-free survival (DFS) between 10% and 25%. On the other hand, high-dose chemotherapy regimens given in combination with bone marrow transplantation (BMT) produce a CR rate that ranges from 40% to 80% and a 3-year DFS of approximately 40%. We report the 5-year results of a prospective study in patients with refractory HD who were treated with three courses of intensive chemotherapy without BMT. PATIENTS AND METHODS Thirty-nine adult patients with refractory HD were treated with three courses of intensive chemotherapy. Each cycle of chemotherapy comprised vindesine 1 mg/m2/d in continuous intravenous (IV) infusion from day 1 to day 5; Adriamycin (doxorubicin; Roger Bellon Laboratories, Neuilly, France) 40 mg/m2/d in continuous IV infusion from day 1 to day 3; carmustine 140 mg/m2/d at day 3; etoposide 200 mg/m2/d from day 3 to day 5; and methylprednisolone 120 mg/m2/d from day 1 to day 5. After the third cycle of chemotherapy, irradiation (20 Gy) was performed whenever possible and depended on previous irradiation. RESULTS At the end of the treatment, 31 patients (79%) were in CR. Among these patients, 10 relapsed after a median time of 3 months. The overall 5-year survival rate was 46%. The freedom from progression (FFP) and the freedom from treatment failure (FFTF) rates were 48% and 43%, respectively. The main toxicities were hematologic (neutropenia and thrombocytopenia) and digestive. Four patients died due to treatment-related complications (two from septic shocks, one from respiratory insufficiency, and one from posttransfusional AIDS). CONCLUSION The results of this study seem to be comparable to those results obtained with high-dose chemotherapies with autologous BMT.

PURPOSE Acute and chronic graft-versus-host disease (GVHD) continues to be the major causes of morbidity and mortality after allogeneic bone marrow transplantation (BMT). In this study, we have evaluated the clinical effects of selective in vitro T-cell depletion of donor allogeneic bone marrow by using a single monoclonal antibody ([MoAb] anti-T12, CD6) and rabbit complement. This antibody recognizes mature T cells, but not other cellular elements such as natural-killer (NK) cells, B cells, and myeloid precursors. PATIENTS AND METHODS From August 1983 to April 1991, 112 consecutive adult patients with hematologic malignancies underwent BMT with bone marrow from HLA-identical sibling donors. Marrow was harvested and depleted of mature T lymphocytes ex vivo by the use of three rounds of incubation with an anti-T12 antibody and rabbit complement. The preparative regimen consisted of cyclophosphamide and fractionated total body irradiation (TBI) in 108 patients. No patients received prophylactic immune suppression post-BMT. Purgation by anti-T12 was used as the only method for the prevention of GVHD. RESULTS Twenty patients (18%) developed acute GVHD (grade 2 to 4); only eight patients developed chronic GVHD. The incidence of GVHD did not increase significantly with age. Only three of 112 patients (2.7%) exhibited acute graft failure. One patient developed late graft failure that was associated with cytomegalovirus (CMV) infection. Within the subset of 50 patients who had not previously undergone unsuccessful conventional therapy (acute leukemia in first remission or chronic myelogenous leukemia [CML] in stable phase), we estimated by the Kaplan-Meier method that the probability of disease-free survival was 50% at 3 years post-BMT, with a median follow-up of 44 months. The treatment-related mortality rate in this group was only 14% and was independent of patient age. CONCLUSIONS We conclude that selective in vitro T-cell depletion with an anti-T12 monoclonal antibody effectively reduces the incidence of both acute and chronic GVHD after allogeneic BMT without compromising engraftment. Moreover, depletion of CD6-positive cells from donor marrow obviates the need to administer immune suppressive medications to the majority of patients. This approach reduces the morbidity and mortality of allogeneic BMT and permits the BMT of older patients.

PURPOSE This phase II trial was designed to evaluate the feasibility, toxicity, response rates, and survival for neoadjuvant chemotherapy and radiotherapy (RT) followed by surgical resection in newly diagnosed patients with surgically staged IIIA non-small-cell lung carcinoma (NSCLC). PATIENTS AND METHODS Previously untreated patients with NSCLC underwent bronchoscopy, chest and abdominal computed tomography (CT), bone scan, and surgical staging of the mediastinum. Neoadjuvant treatment consisted of concurrent chemotherapy and RT. Patients then underwent surgical resection, which was followed in turn by additional chemotherapy and RT. Chemotherapy included cisplatin 100 mg/m2 on days 1 and 29, vinblastine 3 mg/m2 on days 1 and 3 and 29 and 31, and fluorouracil (5-FU) 30 mg/kg/d by infusion on days 1 to 3 and 29 to 31 (FVP). RT began on day 1 and included 3,000 cGy in 15 fractions. Surgery took place on day 55, and one more cycle of chemotherapy and an additional 3,000 cGy of RT began on day 85. RESULTS Forty-one eligible patients (median follow-up, 53 months) were studied. N2 disease was present in 80%, whereas 20% had T3N0 or T3N1 lesions. Response to neoadjuvant chemotherapy and RT included no complete responses (CR), 21 (51%) partial responses (PR) or regressions, 19 (46%) stable disease (SD), and one (2%) progressive disease (PD). Thirty-one patients underwent surgery, and 25 were resected. In four of the 25 resection specimens, no viable tumor was present, whereas in three of the six unresectable patients, extensive biopsy results demonstrated only necrotic tumor. The maximum response achieved using all protocol treatment was 27 (66%) CRs, seven (17%) PRs or regression, six (15%) SDs, and one (2%) PD. Toxicity was substantial and primarily hematologic. There were six (15%) treatment-related deaths, which included three perioperative deaths and three chemotherapy-related toxicity deaths. The Kaplan-Meier curve indicated a 1-year survival of 58% and a median survival of 15.5 months. Nine patients (22%) remain disease-free. CONCLUSIONS There was a reasonably high rate of PR associated with concurrent neoadjuvant chemotherapy and RT, and a high percentage of patients who ultimately were rendered completely disease-free. However, treatment-related morbidity and mortality was common. Median survival seemed to be only modestly improved beyond that achieved with less intensive means of treatment. However, a group has emerged of patients who enjoy prolonged disease-free survival and possible cure.

Published: February 2017

PURPOSE AND METHODS Diffuse small cleaved-cell lymphoma (DSCL) is a relatively uncommon non-hodgkin's lymphoma (NHL) in the United States and has not been the subject of recent in-depth study of factors predictive of outcome. It is unique among the NHL of intermediate grade because there is no evidence of a curable subset of patients. To investigate whether any laboratory data might predict outcome, we studied 33 cases collected during a 12-year period and correlated morphology, immunohistochemistry, and serum lactate dehydrogenase (LDH) with clinical data and outcome. RESULTS We found that proliferative rate (Ki-67), cell lineage (T v B cell), and serum LDH were associated with significant differences in survival. A Ki-67 value greater than or equal to 20% was associated with a median survival of 20 months compared with 80 months for lower values (P = .0002); patients with tumors of T-cell lineage had a median survival of 20 months compared with 40 months for those with B-cell neoplasms (P = .0143); and a serum LDH greater than 225 IU/L was associated with a median survival of 8 months compared with 40 months for lower LDH levels (P = .0004). Blastoid morphology was also linked to a trend toward poor outcome (P = .08). Neither a history of low-grade lymphoma nor the presence of residual immunologically detectable follicles influenced outcome (P = .93 and .97, respectively). CONCLUSION We conclude that high Ki-67, high LDH, and T-cell lineage each identify DSCL patients with poor outcome.
