PURPOSE To define the toxicity, imaging, and biodistribution characteristics of iodine 131-labeled monoclonal antibody F19 (131I-mAbF19). MAbF19 recognizes the fibroblast activation protein (FAP), a cell-surface glycoprotein not present in most normal tissues, but abundantly expressed by reactive stromal fibroblasts of epithelial cancers, including more than 95% of primary and metastatic colorectal carcinomas. PATIENTS AND METHODS 131I-mAbF19 was administered intravenously to 17 patients with hepatic metastases from colorectal carcinoma who were scheduled for resection of localized metastases or insertion of hepatic artery catheter for regional chemotherapy. Seven to 8 days before surgery, patients received 131I-mAbF19 at three dose levels, with at least four patients entered at each level. RESULTS No toxicity associated with intravenous 131I-mAbF19 administration was observed. Tumor images were obtained on planar and single-photon emission tomography (SPECT) scans in 15 of 17 patients with hepatic metastases, tumor-infiltrated portal lymph nodes, and/or recurrent pelvic disease. The smallest lesion visualized was 1 cm in diameter. The optimal time for tumor imaging was 3 to 5 days after 131I-mAbF19 administration. The use of image registration techniques allowed precise anatomic localization of 131I-mAbF19 accumulation. Immunohistochemical analysis of biopsy tissues showed expression of FAP in the tumor stroma (but not in normal liver) in all patients studied and confirmed that the FAP-positive tumor stromal fibroblasts were interposed between the tumor capillaries and the malignant colon epithelial cells. At the time of surgery, tumor-to-liver ratios up to 21:1 and tumor-to-serum ratios up to 9:1 were obtained. The fraction of the injected 131I-mAbF19 dose per gram tumor (%ID/g tumor) localized to hepatic metastases at the time of surgery ranged from 0.001% to 0.016%. CONCLUSION The FAP tumor fibroblast antigen is highly expressed in primary and metastatic colorectal carcinomas and shows limited expression in normal adult tissues. This highly selective expression pattern allows imaging of colorectal carcinoma lesions as small as 1 cm in diameter on 131I-mAbF19 scans. Because of the consistent presence of FAP in the stroma of epithelial cancers and the accessibility of FAP-positive tumor stromal fibroblasts to circulating monoclonal antibodies (mAbs), this study suggests possible diagnostic and therapeutic applications of humanized mAbF19 and mAbF19 constructs with novel immune and nonimmune effector functions.

PURPOSE This phase II study was conducted to evaluate the efficacy and toxicity of docetaxel in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Docetaxel was administered to 29 patients with unresectable stage III and IV NSCLC at a dose of 100 mg/m2 intravenously (IV) over 1 hour every 21 days. No premedication was given to the first 16 patients. Premedication with diphenhydramine was instituted for the remainder. No patient had previously received chemotherapy. Seven patients had undergone prior radiation therapy. RESULTS All patients were assessable for response and toxicity. Eleven of 29 patients (38%) had a major objective response (95% confidence interval, 21% to 58%). The median duration of response was 5.3 months. Febrile neutropenia occurred in 41% of patients and in 11% of 134 courses of docetaxel. Nonhematologic toxicities included infusion-related hypersensitivity reactions, fluid retention, rash, alopecia, and sensory neuropathy. Premedication with diphenhydramine did not decrease the incidence of infusion-related hypersensitivity reactions. CONCLUSION At this dose and schedule, docetaxel demonstrates significant antitumor activity in patients with advanced NSCLC. Further investigations of this agent in NSCLC are indicated.

PURPOSE The aim of this study was to analyze the link between fluorouracil (FU) systemic exposure and tumor response and overall survival. PATIENTS AND METHODS One hundred eighty-six patients (162 men, 24 women) with head and neck cancer were studied. All received cisplatin plus FU for three cycles as first-line chemotherapy. The treatment consisted of cisplatin (100 mg/m2 intravenously [IV]) followed by a 5-day continuous venous infusion of FU (1 g/m2/d). The median follow-up duration for the 104 patients alive was 24 months. For each cycle, we calculated the area under the curve over the duration of pharmacokinetic follow-up (AUC0-105 h) for plasma FU. For each patient, we analyzed the averaged AUC0-105 h and the averaged total dose for the three cycles. RESULTS The response rate was 30% complete responses (CRs), 22% partial responses (PRs) more than 75%, 25% PRs less than 75%, and 23% no response (NR). Medians for averaged AUC and dose per cycle were 27,906 ng/mL h (first through third quartile, 25,398 to 31,060) and 7,000 mg (first through third quartile, 6,200 to 7,833), respectively. The tumor response was significantly linked to tumor stage (P < .001) and to averaged AUC (P = .05), but not to averaged dose. Analysis of parameters (continuous variable) expressing FU treatment intensity showed that dose did not influence survival contrary to the AUC (P = .001). The AUC remains significant (P = .025) in a multivariate analysis including tumor stage, demonstrating that the greater the FU systemic exposure, the longer the survival. CONCLUSION These results strengthen the interest of individual FU dose adaptation based on pharmacokinetics.

PURPOSE To investigate the results of treatment and factors that affect prognosis in adult patients undergoing high-dose therapy and autologous bone marrow transplantation (ABMT) for lymphoblastic lymphoma (LBL). PATIENTS AND METHODS The study was a retrospective analysis of 214 patients reported to the Lymphoma Registry of the European Group for Bone Marrow Transplantation (EBMT) between January 1981 and December 1992, including 105 patients undergoing marrow transplantation in first complete remission (CR). Data on all patients were reviewed, and analysis of prognostic factors conducted. RESULTS The actuarial overall survival rate at 6 years for the entire group is 42%. Disease status at ABMT was the major determinant of outcome: 6-year actuarial overall survival was 63% for patients transplanted in first CR, compared with 15% for those with resistant disease at the time of transplantation. Transplantation in second CR resulted in a 31% rate of actuarial overall survival at 6 years. For patients transplanted in first CR, univariate analysis failed to identify any factors at presentation that predicted for outcome after transplantation. CONCLUSION These results suggest that ABMT is effective therapy for adults with LBL, even in patients with disease that is resistant to conventional-dose therapy. Results for patients transplanted in second CR are superior to those reported for conventional-dose salvage regimens. The results in first CR require verification in a prospective randomized clinical study.

PURPOSE The aim of our study was to compare in a multicentric randomized trial two regimens widely used in the treatment of advanced-stage intermediate- to high-grade non-Hodgkin's lymphoma and to assess whether a third-generation regimen (methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin [MACOP-B]) was superior to a second-generation regimen (procarbazine, methotrexate with leucovorin, doxorubicin, cyclophosphamide, and etoposide [ProMACE-MOPP]). PATIENTS AND METHODS Between January 1987 and August 1991, 221 patients with diffuse intermediate- to high-grade non-Hodgkin's lymphoma (Working Formulation groups F, G, H, and K), stage II bulky (> 10 cm), III, or IV, were randomized by the Non-Hodgkin's Lymphoma Cooperative Study Group (NHLCSG) to receive ProMACE-MOPP for six cycles or MACOP-B for 12 weeks. Survival, progression-free survival, and disease-free survival were determined, and multivariate analysis of prognostic factors was performed. RESULTS In the two groups of patients, there was no significant difference in terms of complete remission (CR) rate (49.1% with ProMACE-MOPP and 52.3% with MACOP-B), 3-year overall survival rate (45.2% with PROMACE-MOPP and 52.3% with MACOP-B), and 3-year progression-free survival rate (36.4% with ProMACE-MOPP and 36.1% with MACOP-B). In terms of toxicity, no significantly greater toxicity occurred in either arm. Overall toxicity was acceptable. The most frequent side effects were grade II through IV leukopenia, infection, mucositis, and anemia. Treatment-related deaths were equally distributed. CONCLUSION No significant differences in terms of efficacy and/or toxicity between ProMACE-MOPP and MACOP-B are evident. These results are consistent with recent randomized trials showing that the new-generation aggressive regimens are no better than previous ones.

PURPOSE To determine the maximum-tolerated dose (MTD), dose-limiting toxicity, and plasma concentrations of orally administered etoposide (VP-16) in pediatric oncology patients. PATIENTS AND METHODS In a phase I study, 20 children with refractory solid tumors received oral VP-16 (the intravenous preparation diluted with sodium chloride) three times daily for 21 days. Daily dose levels studied were 50 mg/m2 (n = 5), 60 mg/m2 (n = 7), and 75 mg/m2 (n = 8). VP-16 concentrations were measured in blood samples collected on days 1, 7, 14, and 21. RESULTS Grade 3 to 4 thrombocytopenia and/or neutropenia causing interruption of the 21-day course or persisting for more than 7 days after the last day of chemotherapy was seen at all dose levels, but was not dose-limiting. One patient treated at the 50-mg/m2 daily dose died of sepsis. At the 75-mg/m2 dose level, diarrhea was dose-limiting. Estimated plasma VP-16 concentrations were greater than 1 micrograms/mL for median periods of 9.4, 15.4, and 13.5 hours per day at daily doses of 50, 60, and 75 mg/m2, respectively. Responses were observed in seven of 14 patients who received at least one additional course of etoposide after a rest period of 7 days. There was one complete and two objective responses. Four patients were considered to have stable disease. CONCLUSION The intravenous preparation of VP-16 administered orally appears to be well tolerated by heavily pretreated pediatric patients. On the three-times daily, 21-day schedule, a daily dose of 75 mg/m2 exceeds the MTD, with diarrhea as the dose-limiting toxicity. The recommended dose for oral etoposide is 60 mg/m2/d administered every 8 hours.

PURPOSE To correlate in vitro characteristics of tumor-infiltrating lymphocytes (TIL) with clinical response to TIL immunotherapy in patients with metastatic melanoma. PATIENTS AND METHODS Forty-one melanoma patients undergoing 43 separate treatment courses with TIL and interleukin-2 (IL-2) from December 1990 through November 1992 were studied prospectively. Multiple patient and treatment characteristics were evaluated for response correlates. In addition, TIL were assayed within 7 days of infusion for characteristics such as doubling time, cell-surface phenotype, autologous tumor lysis in 4-hour chromium-51 release assays, and cytokine secretion following autologous tumor stimulation. RESULTS Nine patients experienced complete or partial tumor regressions. Clinical parameters such as age, sex, sites of disease, performance status, and prior therapies were similar in responders and nonresponders. Treatment variables such as the cumulative IL-2 dose and concomitant administration of cyclophosphamide or interferon (IFN)-alpha were not predictive of response, although responders received 33% more TIL. However, statistically significant differences in favor of clinical response were noted for extranodal source of TIL (v lymph node), shorter culture duration (mean, 38 v 47 days), shorter TIL doubling time (2.6 v 3.7 days), greater autologous tumor lysis by TIL (30% v 15%; effector-to-target [E:T], 40:1), and secretion of granulocyte-macrophage colony-stimulating factor (GM-CSF) by TIL following autologous tumor stimulation (six of nine responders v eight of 32 nonresponders). CONCLUSION The associations of TIL lysis of autologous tumor and younger TIL age with clinical response observed in this study are supportive of previous reports, and these findings will be useful in designing future clinical trials. The new observation correlating GM-CSF secretion by TIL with clinical response is interesting and needs further substantiation.

PURPOSE To evaluate incidence, time trends, geographic distribution, clinicopathologic presentation features, and prognostic factors for survival and relapse in gastrointestinal (GI) non-Hodgkin's lymphomas (NHLs). PATIENTS AND METHODS Over a 9-year period (1983 to 1991), 2,446 new NHL cases were recorded in a Danish population-based NHL registry (Danish Lymphoma Study Group [LYFO]). Of these, 306 (12.5%) were GI NHL (175 gastric, 109 intestinal, and 22 both sites). LYFO registry data were used for incidence rate (IR) assessment, and time-trend and geographic distribution analysis. Relative risk (RR) values for survival and relapse were identified by multivariate analysis. RESULTS The mean annual, age-standardized IRs for gastric and intestinal NHL were 0.71/10(5) and 0.48/10(5) per year, respectively. Age-specific IRs for both localizations showed an exponential increase as a function of age. Time-trend analysis for the period 1983 to 1991 showed stable IRs for both localizations. Intestinal NHL was more frequent in males (male-to-female ratio, 2.0 v 1.3), and had a higher occurrence of disseminated disease, constitutional symptoms, high-grade histology, and T-cell phenotype (10% v 2%). Gastric NHL had more low-grade cases (38% v 19%), and almost all were of the mucosa-associated lymphoid tissue (MALT) type. The cause-specific 5-year survival rate was 63% for gastric NHL and 49% for intestinal NHL. The Musshoff staging system was an excellent discriminator between truly localized (stage I and II1) and disseminated cases (stage II2 to IV), particularly for gastric NHL, for which no survival difference was found between surgically and conservatively stage localized cases. CONCLUSION (1) No increase in the incidence of GI NHL was found over a 9-year observation period; (2) nonrandom spatial distribution of new GI NHL cases was observed; (3) factors that significantly increased the risk of death in gastric cases were presence of B symptoms (RR = 3.3), clinical stage is more than II1 (RR = 3.0), age more than 72 years (RR = 2.4), and elevated serum lactate dehydrogenase (s-LDH) level (RR = 2.0); and factors that increased the risk of death in intestinal cases were presence of B symptoms (RR = 3.2), age more than 58 years (RR = 2.8), and clinical stage more than I (RR = 2.1); (4) factors that significantly increased the risk of relapse in gastric cases were male sex and no radiotherapy in primary treatment; and in intestinal cases were T-cell phenotype and no surgery in primary treatment; (5) surgical staging, as opposed to thorough noninvasive staging, did not improve staging accuracy and final outcome in localized gastric NHL.
Quantitating familial cancer risk: a resource for clinical oncologists.
Authors: Offit K , Brown K 
Published: February 2017

PURPOSE Because a family history of cancer constitutes an important risk factor, estimation and communication of cancer risk can facilitate efforts toward early detection and prevention. This review provides a resource for health professionals called to draw upon a multidisciplinary literature to provide quantitative risk estimates to families with cancer. DESIGN Descriptive population-derived, epidemiologic, genetic, genetic epidemiologic, and molecular studies are critically reviewed in the context of cancer genetic counseling. RESULTS Data are presented that document the increased lifetime relative risk to relatives of individuals with cancers of the breast, ovary, colon, prostate, or other sites. In general, risk ratios are poorly suited for clinical counseling. Age-specific absolute risks are presented for first-degree relatives of individuals affected by cancers of the breast, ovary, and colon. The derivation of Mendelian and Bayesian risk estimates in the setting of well-defined cancer family syndromes, and the growing role of DNA testing in more accurately assessing these risks, are discussed. Such carrier testing requires careful psychologic and ethical considerations. CONCLUSION Multidisciplinary cancer genetic counseling is an emerging resource available to physicians who care for families with common adult malignancies.

PURPOSE This study investigated prognostic factors in nonmetastatic high-grade extremity osteosarcoma and the prognosis following resection of subsequent pulmonary metastases, with emphasis on the effect of chemotherapy-induced tumor necrosis. PATIENTS AND METHODS We reviewed 111 consecutive patients with high-grade nonmetastatic extremity osteosarcoma treated with preoperative chemotherapy and surgical resection, with additional review of 36 patients who had subsequent pulmonary metastases resected. RESULTS The overall 5-year survival rate was 53%. In resected primary tumors, tumor-free resection margin (P < .001) and increasing chemotherapy-induced tumor necrosis (> 90% threshold, P < .003) correlated with increased metastasis-free survival. Relative risk factors for metastases were as follows: tumor-containing resection margin (most likely to metastasize); poor response to preoperative chemotherapy and/or lack of postoperative chemotherapy (next worse prognosis); and excellent response to preoperative chemotherapy (> or = 90% necrosis) combined with postoperative chemotherapy (best prognosis). The 5-year survival rate following pulmonary metastasis resection was 23%, whereas a 0% 4-year survival rate followed development of bony metastases (P < .001). The extent of tumor necrosis in resected pulmonary metastases did not affect prognosis. Survival was best in patients with three or fewer pulmonary nodules (P < .048), four or fewer recurrent pulmonary nodules (P < .047), unilateral pulmonary metastases (P < .037), or longer intervals between primary tumor resection and metastases (P < .082). CONCLUSION Intensive preoperative and postoperative chemotherapy combined with complete resection of both primary and metastatic pulmonary osteosarcomas is justified, with a goal of 100% tumor necrosis and excision. Although current treatment regimens allow effective salvage therapy for a few patients with pulmonary metastases, more effective systemic treatment is needed.
Very low-dose warfarin prophylaxis to prevent thromboembolism in women with metastatic breast cancer receiving chemotherapy: an economic evaluation.
Authors: Rajan R , Gafni A , Levine M , Hirsh J , Gent M 
Published: February 2017

PURPOSE A recent double-blind, randomized trial demonstrated that very low-dose warfarin (VLDW) reduced the incidence of venous thromboembolism (VTE) without increasing the rate of bleeding in women with metastatic breast cancer receiving chemotherapy. We have evaluated the economic impact on the health care system of using VLDW in such patients. METHODS The records of patients entered onto the trial and a simultaneous, fully allocated, costing model for a tertiary care hospital in Hamilton, Canada were used to determine the difference in costs associated with the care of patients with and without VLDW. RESULTS The cost of providing VLDW was $ 21,854 (Canadian dollars) per 100 patients. This therapy led to a reduction in costs of $ 24,297 per 100 patients, thus saving the health care system $ 2,443 per 100 patients. In the sensitivity analysis, VLDW prophylaxis still did not increase health care costs unless the cost of VLDW was greatly increased, the cost of treating thromboembolic episodes was markedly reduced, or the incidence of either VTE or bleeding with VLDW was increased above the rates observed in the trial. CONCLUSION We conclude that for women receiving chemotherapy for metastatic breast cancer, the benefits of VLDW can be realized without increased health care costs.
