Abstract
BACKGROUND AND AIMS Colorectal cancer (CRC) screening guidelines include screening-colonoscopy and sequential high sensitivity fecal occult blood testing (HSgFOBT), with expectation of similar effectiveness based on the assumption of similar high adherence. However, adherence to screening-colonoscopy compared to sequential HSgFOBT has not been reported. In this randomized clinical trial, we assessed adherence and pathology findings for a single screening-colonoscopy versus sequential and non-sequential HSgFOBT. METHODS Participants aged 40-69 were enrolled in three centers, which represented different clinical settings. Participants were randomized into a single screening-colonoscopy arm versus sequential HSgFOBT arm comprised of 4-7 rounds. Initial adherence to screening-colonoscopy and sequential adherence to HSgFOBT, follow-up colonoscopy for positive HSgFOBT tests, crossover to colonoscopy, and detection of advanced neoplasia or large serrated lesions (ADN-SER) were measured. RESULTS 3,523 participants were included in the trial with 1761 and 1762 participants randomized to the screening-colonoscopy and HSgFOBT arms, respectively. Adherence was 1473 (83.6%) for the screening-colonoscopy arm versus 1288 (73.1%) for the HSgFOBT arm after one round (RR=1.14, [95% CI 1.10-1.19] P ≤0.001), but only 674 (38.3%) over four sequential HSgFOBT rounds (RR=2.19, [95% CI 2.05-2.33]). Overall adherence to any screening increased to 1558 (88.5%) in the screening-colonoscopy arm during the entire study period and 1493 in the HSgFOBT arm (84.7%) (RR=1.04, [95% CI 1.02-1.07]). 436 (24.7%) participants crossed over to screening-colonoscopy over the first four rounds. ADN-SER were detected in 121 (8.2%) of the 1473 participants in the colonoscopy arm who were adherent to protocol in the first 12 months of the study, whereas the detection of ADN-SER among those who were not sequentially adherent (N=709) to HSgFOBT was subpar (0.6%) (RR=14.72, [95% CI 5.46-39.67]) when compared to those who were sequentially adherent (3.3%) (N=647) (RR=2.52, [95% CI 1.61-3.98]) to HSgFOBT in the first four rounds. When including colonoscopies from HSgFOBT patients who were never positive yet crossed over (N=1483), 5.5% of ADN-SER were detected (RR=1.50, [95% CI 1.15-1.96]) in the first four rounds. CONCLUSIONS Observed adherence to sequential rounds of HSgFOBT was suboptimal when compared to a single screening-colonoscopy. The detection of ADN-SER was inferior when non-sequential HSgFOBT adherence was compared to sequential adherence. However, the greatest number of ADN-SER was detected among those who crossed over to colonoscopy and opted to receive a colonoscopy. The effectiveness of a HSgFOBT screening program may be enhanced if crossover to screening-colonoscopy is permitted.

Abstract
Phase II data suggest a benefit to autotransplantation for aggressive T-cell non-Hodgkin lymphoma (T-NHL) in first remission; randomized trials have yet to validate this. We performed a retrospective analysis of aggressive T-NHL patients in the intergroup randomized consolidative autotransplant trial (SWOG 9704). Of the 370 enrolled, 40 had T-NHL: 12 were not randomized due to ineligibility (n = 1), choice (n = 2), or progression (n = 9), leaving 13 randomized to control and 15 to autologous stem cell transplantation (ASCT). Two ASCT patients refused transplant and one failed mobilization. The 5-year landmark PFS/OS estimates for ASCT vs. control groups were 40% vs. 38% (p = .56), and 40% vs. 45% (p = .98), respectively. No difference was seen based on IPI, or histologic subtype. Only 1/7 receiving BCNU-based therapy survived vs. 4/5 receiving TBI. Aggressive T-NHL autotransplanted in first remission did not appear to benefit from consolidative ASCT. This and the 30% who dropped out pre-randomization mostly to progression, suggests that improved induction regimens be developed.

Abstract
Eltrombopag is a thrombopoietin agonist and has been used in aplastic anemia and post-transplantation thrombocytopenia. The c-MPL receptor is present on hematopoietic stem cells. There are no reports of eltrombopag utilization for improving poor graft function in the post-transplant setting. Here were report a case of a young female with post-transplant poor graft function as evident from the low absolute neutrophil count, anemia, and thrombocytopenia on day 60. Eltrombopag was started on day 72 and resulted in improvement in all 3 cell lines. The counts continued to be stable even after eltrombopag was discontinued. The patient tolerated the drug without significant side effects for 1 year.

Abstract
Patients with chronic lymphocytic leukemia (CLL) who progress to Richter transformation (RT) have a poor prognosis. Multi-agent chemotherapy regimens do not have good response rates. There are few case reports on the use of ibrutinib in RT. Here, we present a patient who was heavily pretreated for CLL, including allogeneic stem cell transplant, and progressed to RT. She had a mixed response to multi-agent chemotherapy and was started on ibrutinib. She had a complete response for 16 months on single-agent ibrutinib with minimal toxicity.

Abstract
Lung cancer is the major cause for cancer-related death in the US. Although advances in chemotherapy and targeted therapy have improved the outcome of metastatic non-small-cell lung cancer, its prognosis remains dismal. A deeper understanding of the complex interaction between the immune system and tumor microenvironment has identified immune checkpoint inhibitors as new avenue of immunotherapy. Rather than acting directly on the tumor, these therapies work by removing the inhibition exerted by tumor cell or other immune cells on the immune system, promoting antitumoral immune response. To date, two programmed death-1 inhibitors, namely nivolumab and pembrolizumab, have received the US Food and Drug Administration approval for the treatment of advanced non-small-cell lung cancer that failed platinum-based chemotherapy. This manuscript provides a brief overview of the pathophysiology of cancer immune evasion, summarizes pertinent data on completed and ongoing clinical trials involving checkpoint inhibitors, discusses the different strategies to optimize their function, and outlines various challenges that are faced in this promising yet evolving field.

Abstract
Abstract
Background: Niclosamide, an anthelminthic drug, has demonstrated anti-cancer potential in variety of malignancies. However only a limited number of studies have been performed in lymphoma models, therefore we hypothesized that niclosamide may also have anti-cancer potential on B-cell lymphomas.
Materials and Methods: Established B lymphoma cell lines were exposed to different concentrations of niclosamide and IC50 was calculated using GraphPad Prism 6.0 software. Cell viability and proliferation were assessed by CellTiter-Blue and trypan blue exclusion assays. Apoptosis was assessed by flow cytometry following Annexin-V/ propidium iodide staining. Gene expression changes were studied using GeneChip Human Transcriptome Array 2.0. Colony forming assays were performed in methylcellulose. Ultrastructural cellular changes were studied with electron microscopy. Peripheral blood mononuclear cells (PBMCs) from individuals without active cancer and from patients with different hematologic disorders, were also exposed with niclosamide.
Results: Treatment with niclosamide resulted in time-and dose- dependent apoptosis, cytotoxicity and inhibition of proliferation in different lymphoma cell lines including vincristine-refractory cell line. The IC50 of lymphoma cells lines is as follows: Daudi: 0.33 ìM; HBL-2: 0.57 ìM; KOPN-8: 0.72 ìM; Ramos: 0.53 ìM and SU-DHL4-VR: 0.45 ìM. Niclosamide also inhibited clonal growth in semi-solid media. Gene expression changes were studied in Daudi and KOPN-8 cells treated with 2.5 ìM Niclosamide for 3 and 6 hours. 96 genes were consistently overexpressed, 59 down-regulated. 10 genes involved in the tumor necrosis factor (TNF) pathway and 10 genes involving the DNA damage pathway were overexpressed. 13 out of the 59 down-regulated genes were involved in mitochondrial function. Electron microscopy showed that filopodia increased and lipid vacuoles developed whereas mitochondria were less numerous in KOPN-8 cells. The viability of PBMCs from 8 individuals without lymphoma was unchanged when incubated with niclosamide, whereas niclosamide showed significant cytotoxicity in a patient with mantle cell lymphoma (MCL).
Conclusion: Niclosamide effectively inhibits the proliferation of B lymphoma cell lines, including vincristine-refractory lymphoma cells, and induces apoptosis at concentrations non-toxic to PBMCs. Interestingly, niclosamide exhibited cytotoxic activity against MCL cells - a finding worth testing further in this difficult-to-treat disease. The mechanism of action of Niclosamide may involve the TNF receptor pathway, mitochondrial function and DNA damage response pathway. We plan to elucidate further specific mechanism(s) of action, and evaluate synergistic effects with other antineoplastic agents, and perform in vivo studies.

Abstract
BACKGROUND Problems with sexual functioning are common following therapy for breast and gynecologic cancers, although there are few effective treatments. OBJECTIVE To assess the impact of ArginMax, a nutritional supplement comprised of extracts of L-arginine, ginseng, gingko, and damiana, as well as multivitamins and minerals, on sexual functioning and quality of life in female cancer survivors. METHODS This was a 12-week, randomized, placebo-controlled trial of eligible patients who were 6 months or more from active treatment and reporting problems with sexual interest, satisfaction, and functioning after therapy. The participants took 3 capsules of Arginmax or placebo twice daily. Outcome measures were the Female Sexual Function Inventory (FSFI) and the Functional Assessment of Cancer Therapy - General (FACT-G). Assessments were done at baseline, 4, 8, and 12 weeks. RESULTS 186 patients with a median age of 50 years were accrued between May 10, 2007 and March 24, 2010. 76% of the patients were non-Hispanic white. Most had breast or a gynecologic cancer (78% and 12%, respectively). At 12 weeks, there were no differences between the ArginMax group (n = 96) and placebo (n = 92) group in sexual desire, arousal, lubrication, orgasm,satisfaction or pain. However, FACT-G total scores were significantly better for participants who took ArginMax compared with those who took placebo (least squares [LS] means, 87.5 vs 82.9, respectively; P = .009). The Fact-G subscales that were most affected were Physical (25.37 vs. 23.51, P = .001) and Functional Well-Being (22.46 vs. 20.72, P = .007). Toxicities were similar for both groups. LIMITATIONS Study results are limited by a lack of data on the participants' psychological and physical symptoms and sexual partner variables. CONCLUSIONS ArginMax had no significant impact on sexual functioning, but patient quality of life was significantly better at 12 weeks in participants who received ArginMax.

Abstract
BACKGROUND Relative survival (RS) for patients with laryngeal cancer in the US population has yet to be described. Additionally, survival of patients with laryngeal cancer has demonstrated socioeconomic and racial disparities which have not been previously examined through the lens of RS. MATERIALS AND METHODS Data on 58,814 patients with laryngeal cancer were obtained from the National Cancer Database. Patients were diagnosed between 1998 and 2006, and had at least 5 years of follow-up. Birth-, year-, age-, sex- and race-specific matched life expectancies were used to estimate expected survival. Stage-stratified RS rates were calculated with multiple factors assessed for significance. Excess mortality ratios were estimated in multivariate analysis utilizing Poisson regression. RESULTS Younger age, African-American race, uninsured or Medicaid insurance, and treatment at an academic center were all significantly associated with stage IV disease. Uninsured and Medicaid patients demonstrated decreased RS when compared to privately insured individuals. Excess mortality was markedly pronounced in the first year for patients over 50 years old with stage II-IV disease, especially for the over 75-year-old cohort. CONCLUSION Survival disparities for uninsured and Medicaid populations were found, with these patients exhibiting increased excess mortality. Additionally, RS calculations highlight the negative effects of increasing age on survival of patients with laryngeal cancer.

Abstract
BACKGROUND The overall prognosis of multiple myeloma has improved significantly over the last 15 years. We wondered whether the overall improvement would also be seen in unselected patients in an academic center in Northwest Louisiana with a high proportion of minority patients, and if second malignant neoplasms are relevant for our patients. MATERIALS AND METHODS Between 1998 and 2009, 215 patients were treated for multiple myeloma at our center and had complete follow-up until May 2013. RESULTS The mean survival of patients with multiple myeloma increased from 3.25 to 5.34 years, which is comparable to patients treated at larger centers. No prognostic difference was observed in the subgroups of myeloma patients. Among 215 patients followed for the development of secondary cancers, 16 already had a preexisting or concomitant malignancy (7.4%) and 10 developed secondary cancers. Our data indicate a significant background of histologically unrelated cancers and a cumulative incidence of new cancers of about 20% after 10 years of follow-up. Based on SEER data, preexisting or secondary cancers were not statistically increased in our population. CONCLUSIONS The use of autologous transplantation and the introduction of new agents resulted in a significant improvement in the prognosis of multiple myeloma. Other cancers are not statistically increased before or after multiple myeloma is diagnosed and are not prognostically relevant.

Abstract
BACKGROUND Currently, no clinical tools use demographic and risk factor information to predict the risk of finding an adenoma in individuals undergoing colon cancer screening. Such a tool would be valuable for identifying those who would most benefit from screening colonoscopy. METHODS We used baseline data from men and women who underwent screening colonoscopy from the randomized, multicenter National Colonoscopy Study (NCS) to develop and validate an adenoma risk model. The study, conducted at three sites in the United States (Minneapolis, MN; Seattle, WA; and Shreveport, LA) asked all participants to complete baseline questionnaires on clinical risk factors and family history. Model parameters estimated from logistic regression yielded an area under the receiver operating characteristic curve (AUROCC) used to assess prediction. RESULTS Five hundred forty-one subjects were included in the development model, and 1,334 in the validation of the risk score. Variables in the prediction of adenoma risk for colonoscopy screening were age (likelihood ratio test for overall contribution to model, P < 0.001), male sex (P < 0.001), body mass index (P < 0.001), family history of at least one first-degree relative with colorectal cancer (P = 0.036), and smoking history (P < 0.001). The adjusted AUROCC of 0.67 [95% confidence interval (CI), 0.61-0.74] for the derivation cohort was not statistically significantly different from that in the validation cohort. The adjusted AUROCC for the entire cohort was 0.64 (95% CI, 0.60-0.67). CONCLUSION We developed and validated a simple well-calibrated risk score. IMPACT This tool may be useful for estimating risk of adenomas in screening eligible men and women.

Abstract
Efficacy of cisplatin versus cetuximab with radiation in locally advanced head and neck cancer (LAHNC) was evaluated. A total of 96 patients with newly diagnosed LAHNC treated at our institution between 2006 and 2011 with concurrent radiation and cisplatin (group A, n = 45), cetuximab (group B, n = 24), or started with cisplatin but switched to cetuximab because of toxicity (group C, n = 27) were reviewed. Chi-square test, analysis of variance, and log-rank test were used for analysis. The three groups had similar baseline characteristics, except for median age, T stage, albumin levels, hemoglobin levels, performance status, and comorbidities. A complete response (CR) was seen in 77%, 17%, and 67% of patients (P < 0.001), respectively. There was no significant difference in median overall survival (OS) between groups A and C. The median OS for groups A and C was not reached (>65 months), even though it was significantly longer than median OS for group B (11.6 months; P ≤ 0.001). The 2-year OS in groups A and C is significantly higher than that in group B (70% for groups A and C, 22% for group B). There is no significant difference in progression-free survival (PFS) between groups A and C. The median PFS for these groups was not reached (>62 months), and is significantly longer than that for group B (4.3 months; P ≤ 0.001). The 2-year PFS of group A (67%) and group C (76%) was significantly longer than that of group B (20%). Cisplatin with radiation appears to be more efficacious even in suboptimal dosing than cetuximab with radiation in LAHNC but the two groups were not well matched.

Abstract
OBJECTIVES Chemotherapy-induced peripheral neuropathy is frequently a dose-limiting factor in cancer treatment and may cause pain and irreversible function loss in cancer survivors. We tested whether alpha-lipoic acid (ALA) could decrease the severity of peripheral neuropathy symptoms in patients undergoing platinum-based chemotherapy. METHODS Cancer patients 18 years or older were randomly selected to receive either 600 mg ALA or a placebo three times a day orally for 24 weeks while receiving chemotherapy regimens including cisplatin or oxaliplatin. Neuropathy was measured by the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) scale and the NCI Common Toxicity Criteria for Adverse Events neurotoxicity grades. Results from timed functional tests and the Brief Pain Inventory (BPI) were secondary endpoints. RESULTS Seventy of 243 (29 %) patients completed the study (24 weeks). Both the ALA and the placebo arms had a comparable drop-out rate. No statistically significant differences were found between the ALA and the placebo groups for FACT/GOG-Ntx scores, BPI scores, and patients' functional outcomes. CONCLUSION This strategy of oral ALA administration was ineffective at preventing neurotoxicity caused by oxaliplatin or cisplatin. High attrition rates due to poor patient compliance and manner of dosage administration in this trial demonstrated a lack of feasibility for this intervention. Future studies to explore ALA as a neuroprotective agent should take heed of the barriers confronted in this study.

Abstract
BACKGROUND The efficacy of autologous stem-cell transplantation during the first remission in patients with diffuse, aggressive non-Hodgkin's lymphoma classified as high-intermediate risk or high risk on the International Prognostic Index remains controversial and is untested in the rituximab era. METHODS We treated 397 patients who had disease with an age-adjusted classification of high risk or high-intermediate risk with five cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP plus rituximab. Patients with a response were randomly assigned to receive three additional cycles of induction chemotherapy (control group) or one additional cycle of induction chemotherapy followed by autologous stem-cell transplantation (transplantation group). The primary efficacy end points were 2-year progression-free survival and overall survival. RESULTS Of 370 induction-eligible patients, 253 were randomly assigned to the transplantation group (125) or the control group (128). Forty-six patients in the transplantation group and 68 in the control group had disease progression or died, with 2-year progression-free survival rates of 69 and 55%, respectively (hazard ratio in the control group vs. the transplantation group, 1.72; 95% confidence interval [CI], 1.18 to 2.51; P=0.005). Thirty-seven patients in the transplantation group and 47 in the control group died, with 2-year overall survival rates of 74 and 71%, respectively (hazard ratio, 1.26; 95% CI, 0.82 to 1.94; P=0.30). Exploratory analyses showed a differential treatment effect according to risk level for both progression-free survival (P=0.04 for interaction) and overall survival (P=0.01 for interaction). Among high-risk patients, the 2-year overall survival rate was 82% in the transplantation group and 64% in the control group. CONCLUSIONS Early autologous stem-cell transplantation improved progression-free survival among patients with high-intermediate-risk or high-risk disease who had a response to induction therapy. Overall survival after transplantation was not improved, probably because of the effectiveness of salvage transplantation.

Abstract
Superwarfarin vitamin K antagonists are found in rat poisons and are readily available. Pediatric exposures are common but are usually asymptomatic without significant coagulopathy. Superwarfarin intoxication must be considered in any adult who presents with an unexplained coagulopathy with extreme elevation of prothrombin time and partial thromboplastin time with associated depletion of vitamin K dependent factors. If superwarfarin toxicity is confirmed, intentional ingestion should be considered, as a large quantity of ingested rat poison is necessary to induce a coagulopathy. Patients with superwarfin induced coagulopathy require several months of high dose oral and parenteral vitamin K supplementation. We describe two patients with superwarfarin toxicity treated at Louisiana State University Health in Shreveport and review pathophysiology and patient management.

Abstract
BACKGROUND Colorectal cancer is common worldwide and chemoprevention has the potential of reducing the number of individuals who may suffer and perish from this disease. METHODS A randomized placebo controlled pilot study in colorectal cancer patients was performed using calcium carbonate as the test agent in a multi-institutional oncology study group. RESULTS Two hundred twenty volunteers were randomized in the study. The primary goals of compliance, accrual, and toxicity monitoring are presented. Presence of multiple adenomas at study entry and subsequent development of metachronous adenomas were recorded and found to be associated with synchronous adenomas. The secondary endpoint of recurrent adenomas indicated lower rates of new adenoma in the volunteers randomized to the calcium group. CONCLUSION This pilot study indicates the feasibility of enrolling survivors of colorectal cancer as study volunteers in a colorectal neoplasm chemoprevention clinical trial and oral calcium continues to be a potentially effective drug in reducing colorectal adenomas.

Abstract
OBJECTIVES To assess the efficacy of a multiagent taxane-based chemotherapy combined with hormonal therapy in men with metastatic androgen-dependent prostate cancer in a multicenter, cooperative group, single-arm trial. METHODS A total of 41 patients with newly diagnosed metastatic prostate cancer involving both the axial and the appendicular skeletons or viscera were enrolled. Of the 41 patients, 35 were treated with combined androgen blockade and ≤4 cycles of oral estramustine (280 mg orally 3 times daily) and etoposide (50 mg/m(2) daily) for 14 days of each 21-day cycle, with paclitaxel (135 mg/m(2) intravenously within 1 hour) on day 2 of each cycle. Chemotherapy was started within 30 days of the initiation of hormonal therapy. The patients were followed up to determine the progression-free survival. RESULTS The 35 patients received a total of 126 cycles of chemotherapy, with 30 receiving all 4 cycles. The median progression-free survival for the evaluable population was 13 months (95% confidence interval 10-16), with a median overall survival of 38 months (95% confidence interval 28-49). The main toxicities were myelosuppression, with 9 patients experiencing grade 3 or greater neutropenia and 1 developing grade 4 thrombocytopenia. One patient died of neutropenic infection. Thrombosis embolism occurred 4 times (3 of grade 4 and 1 of grade 3), with 1 episode of grade 4 cardiac ischemia. CONCLUSIONS The results of our study have shown that the administration of chemotherapy to this population is feasible, with moderate toxicity. Taxane-based chemotherapy did not demonstrate significant efficacy in this high-risk population of patients with a poor prognosis.

Abstract
BACKGROUND In an effort to optimize nonoperative therapy in patients with locoregionally advanced head and neck squamous cell cancer, the Southwest Oncology Group conducted a phase II trial combining 3-drug taxane-containing induction chemotherapy with accelerated fractionation/concomitant boost radiation and concomitant single-agent cisplatin. METHODS Two induction courses using docetaxel (75 mg/m(2) on day 1), cisplatin (100 mg/m(2) on day 1), and fluorouracil (1000 mg/m(2)/day continuous intravenous infusion days 1-4) were given, with an interval of 21 days. Patients who were stable or responded to the chemotherapy received definitive accelerated fractionation/concomitant boost radiation with concurrent cisplatin (100 mg/m(2)) on days 1 and 22 of radiation. RESULTS There were 74 eligible and evaluable patients enrolled between March 1, 2003, and August 15, 2004; 52 (70%) had stage IV disease. At least 1 grade 3-4 toxicity was experienced by 63 patients (85%) during induction. A total of 61 patients completed induction and began concurrent chemoradiotherapy; 50 (68%) completed all planned treatment. At least 1 grade 3-4 toxicity was noted in 53 of the 58 patients (91%) evaluated for toxicity from concurrent chemoradiotherapy. Two patients died during induction, and 2 during chemoradiation. With a median follow-up of 36 months (range, 14-50), the 2-year and 3-year overall survival estimates were 70% and 64%, with 2-year and 3-year progression-free survival estimates of 66% and 61%, respectively. CONCLUSIONS Three-drug induction chemotherapy followed by accelerated fractionation/concomitant boost radiation and concurrent cisplatin is toxic but feasible within a cooperative group. In this patient cohort with advanced head and neck squamous cell cancer, overall and progression-free survivals were encouraging, justifying further study of this approach.

Abstract
BACKGROUND Antiandrogen withdrawal is a potential therapeutic maneuver for patients with progressive prostate cancer. This study was designed to examine antiandrogen withdrawal effects within the context of a large multi-institutional prospective trial. METHODS Eligibility criteria included progressive prostate adenocarcinoma despite combined androgen blockade. Eligible patients received prior initial treatment with an antiandrogen plus orchiectomy or luteinizing hormone-releasing hormone (LHRH) agonist. Patients were stratified according to type of antiandrogen, type of progression (prostate-specific antigen [PSA] or radiographic), presence or absence of metastatic disease, and prior LHRH agonist versus surgical castration. RESULTS A total of 210 eligible and evaluable patients had a median follow-up of 5.0 years; 64% of patients previously received flutamide, 32% bicalutamide, and 3% nilutamide. Of the 210 patients, 21% of patients had confirmed PSA decreases of >or=50% (95% CI, 16% to 27%). No radiographic responses were recorded. Median progression-free survival (PFS) was 3 months (95% CI, 2 months to 4 months); however, 19% had 12-month or greater progression-free intervals. Median overall survival (OS) after antiandrogen withdrawal was 22 months (20 and 40 months for those with and without radiographic evidence of metastatic disease, respectively). Multivariate analyses indicated that longer duration of antiandrogen use, lower PSA at baseline, and PSA-only progression at study entry were associated with both longer PFS and OS. Longer antiandrogen use was the only significant predictor of PSA response. CONCLUSIONS These data indicate a relatively modest rate of PSA response in patients who were undergoing antiandrogen withdrawal; however, PFS can be relatively prolonged (>or=1 year) in approximately 19% of patients.

Abstract
BACKGROUND Administration of paclitaxel on a weekly schedule in combination with carboplatin is associated with a lower incidence of neuropathy and myelosuppression. The authors conducted subgroup analysis of their randomized phase II study of three different schedules of weekly paclitaxel with carboplatin to determine the efficacy of each regimen in elderly patients (aged > or = 70 years) with advanced non-small-cell lung cancer (NSCLC). METHODS Patients with advanced NSCLC were randomized to one of three different weekly paclitaxel/carboplatin regimens. After four cycles of chemotherapy, those with objective response or stable disease were randomized to weekly paclitaxel or observation as maintenance therapy. Four hundred three patients were enrolled in the study, of whom 111 (28%) were aged 70 years or older. RESULTS The treatment regimen of weekly paclitaxel (100 mg/m for 3 of 4 weeks) and carboplatin (area under the curve = 6 mg/ml/min once every 4 weeks) (arm 1) was associated with the best therapeutic index overall. The median survival and 1-year survival rates were 11.3 months and 50% for patients in the > or =70 years cohort versus 11.2 months and 46% for the <70 years cohort in arm 1. Efficacy results were comparable between the two groups in the other arms as well. Grade 4 neutropenia and febrile neutropenia occurred in 13.6% and 2.3% in the > or =70 years cohort compared with 4.5% and 1.1% in the <70 years cohort in arm 1. CONCLUSION The weekly regimen of paclitaxel administered in combination with carboplatin is tolerated well by elderly NSCLC patients and has comparable efficacy with younger patients.

Abstract
BACKGROUND This phase II study (S9718) evaluated the antineoplastic activity and tolerability of the combination of gemcitabine and cisplatin in previously untreated patients with extensive stage small cell lung cancer (ES-SCLC). METHODS Chemonaive patients with ES-SCLC, received gemcitabine 1250 mg/m intravenously (IV) over 30 minutes on days 1 and 8 and cisplatin 75 mg/m IV over 30 to 60 minutes on day 1. Treatments were repeated every 21 days for a maximum of six cycles. RESULTS A total of 88 patients were enrolled in the study; seven patients were not eligible and one did not receive treatment; 80 patients were fully assessable for survival, response, and toxicity. Objective response was observed in 42 patients (53%; 95% confidence interval [CI]: 41%-64%) with two patients (3%; 95% CI: 0%-8%) achieving a complete response. Median PFS was 5 months (CI, 4.2-5.9 months), and median overall survival was 8.8 months (95% CI: 7.8-9.5 months). The 1- and 2-year survival rates were 27.5% (95% CI: 17.7%-37.3%) and 4% (95% CI: 0%-8%), respectively. The most common toxicity was neutropenia. Grade 3 and 4 neutropenia was noted in 17 (21%) and 17 (21%) patients, respectively. Two patients developed febrile neutropenia, with subsequent full recovery. Twenty-one patients (23%) developed grade 3 thrombocytopenia. Grade 4 thrombocytopenia was seen in only one patient. The most common nonhematologic toxicities included grade 3 and 4 vomiting in 12 (21%) patients and fatigue in nine (10%) patients. Two patients (3%) died of respiratory infections while on treatment. CONCLUSION The combination of gemcitabine and cisplatin is an active and reasonably well tolerated regimen for the treatment of ES-SCLC. It does not appear to offer any compelling advantages over other commonly used two drug regimens in this disease.

Abstract
PURPOSE Tumor hypoxia confers chemotherapy resistance. Tirapazamine is a cytotoxin that selectively targets hypoxic cells. We conducted a phase III clinical trial to determine whether the addition of tirapazamine to paclitaxel and carboplatin offered a survival advantage when used in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Of 396 patients registered, 367 eligible patients were randomly assigned to either arm 1 (n = 181), which consisted of treatment every 21 days with paclitaxel 225 mg/m2/3 h, carboplatin (area under the curve = 6), and tirapazamine 260 mg/m2 in cycle 1 (which was escalated, if tolerable, to 330 mg/m(2) in cycle 2), or arm 2 (n = 186), which consisted of paclitaxel and carboplatin as in arm 1 with no tirapazamine. RESULTS Patient characteristics were similar between the two arms. There were no statistically significant differences in response rates, progression-free survival, or overall survival. Patients on arm 1 had significantly (P < .05) more abdominal cramps, fatigue, transient hearing loss, febrile neutropenia, hypotension, myalgias, and skin rash and were removed from treatment more often as a result of toxicity than patients in arm 2 (26% v 13%, respectively; P = .003). More than 40% of patients did not have the tirapazamine dose escalated, primarily because of toxicity. The trial was closed early after an interim analysis demonstrated that the projected 37.5% improvement in survival (8 v 11 months median survival) in arm 1 was unachievable (P = .003). CONCLUSION The addition of tirapazamine to paclitaxel and carboplatin does not result in improved survival in advanced NSCLC compared with paclitaxel and carboplatin alone but substantially increases toxicity.

Abstract
The simultaneous occurrence of a primary malignant tumor of the lung or pulmonary metastasis in patients with head and neck cancer is uncommon. In response to the question, "Are efforts toward management of cancer in the head and neck region in a person with simultaneous malignant tumor of the lung an exercise in futility?" we present six cases evaluated at the Louisiana State University Health Sciences Center in Shreveport during a 19-year period. Men with squamous cell cancers at both locations and locally advanced malignant tumors of the lung were predominant in this series of patients. Chemoradiation was applied because of extensive disease at one or both neoplastic sites. Long-term survival was not observed in most patients (including the aggressively treated individuals) whose malignant neoplasms were concurrently managed by non-operative means.

Abstract
BACKGROUND Colorectal adenomas are the usual precursors to carcinoma in sporadic and hereditary colorectal cancers (CRC). METHODS A total of 220 CRC patients (stages 0, I, and II) were randomized prospectively in a double-blind pilot study of calcium chemoprevention by using recurrent colorectal adenomas as a surrogate end point. This trial is still in progress, and we report the preliminary findings on adenoma recurrence rates. RESULTS Synchronous adenomas were present in 60% of patients, and cancer confined in a polyp was present in 23% of patients. The overall cumulative adenoma recurrence rate was 31% (19% in the first year, 29% for 2 years, and 35% for 3 years). The recurrence rates were greater for patients with synchronous adenomas: 38% at 3 years (P =.01). Lower stage was associated with higher adenoma recurrence rates (P =.04). Factors including age, sex, site of primary cancer, and whether the cancer was confined to a polyp were not significantly associated with differences in adenoma recurrence rates. CONCLUSIONS The substantial adenoma recurrence rate in patients resected of CRC justifies colonoscopic surveillance on a periodic basis. Patients with higher rates of adenoma recurrences, such as CRC with synchronous adenomas, are ideal subjects for chemoprevention trials.

Abstract
BACKGROUND The objective was to evaluate the efficacy and safety of a novel intratumoral cisplatin/epinephrine injectable gel (CDDP/epi gel) for local control and palliation of tumor-related symptoms in patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS Eighty-seven patients were randomly assigned to either CDDP/epi or placebo gel in this phase III, double-blind study. Tumors were < or =20 cm(3); most recurrences (88%) were in a previously irradiated field. The most symptomatic or threatening tumor was designated as the target tumor. DOSE: 0.25 mL CDDP/epi gel/cm(3) tumor volume. TREATMENTS < or =6 weekly intratumoral injections in an 8-week period. PRIMARY OUTCOMES target tumor response and symptom relief. RESULTS During the blinded phase, 34% (21 of 62) of patients achieved an objective response (CR or PR) in the target tumor treated with CDDP/epi gel vs 0% (0 of 24) treated with placebo gel (p <.001). Responses occurred within a median of four treatments (range, 2-6) and were durable (median, 95 days; range, 34-168+ days). More patients treated with CDDP/epi gel achieved palliative benefit than did those treated with placebo gel (37% vs 12%, p =.036). Most frequent side effects were local pain and local cutaneous reactions, which resolved over 3-12 weeks. Renal and hematologic toxicities were rare. CONCLUSIONS This phase III trial showed that CDDP/epi gel significantly reduces tumor burden, palliates tumor-related symptoms, and is an effective local treatment for recurrent tumors.

Abstract
PURPOSE To explore the efficacy and safety of three regimens of weekly paclitaxel plus carboplatin as initial therapy and the feasibility of subsequent maintenance therapy versus observation in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Four hundred one patients were randomly assigned to one of the following arms: arm 1, paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin (area under the curve [AUC] = 6) on day 1; arm 2, paclitaxel 100 mg/m2 and carboplatin (AUC = 2) weekly for 3 of 4 weeks; or arm 3, paclitaxel 150 mg/m2 cycle 1 and 100 mg/m2 cycle 2 and carboplatin (AUC = 2) weekly for 6 of 8 weeks. Patients who responded (n = 130) at week 16 were randomly assigned to either weekly paclitaxel therapy (70 mg/m2, 3 of 4 weeks; n = 65) or observation (n = 65). RESULTS For the 390 assessable patients, the objective response rates observed with initial therapy were 32% for arm 1, 24% for arm 2, and 18% for arm 3. The median time to progression and median survival times were 30 and 49 weeks for arm 1, 21 and 31 weeks for arm 2, and 27 and 40 weeks for arm 3, respectively. The 1-year survival rates were 47% for arm 1, 31% for arm 2, and 41% for arm 3. CONCLUSION Arm 1, paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin (AUC = 6) administered on day 1, demonstrates the most favorable therapeutic index in patients with advanced NSCLC.

Abstract
OBJECTIVE To determine the safety and efficacy of targeted antitumor therapy with cisplatin/epinephrine injectable gel in patients with advanced squamous cell carcinoma of the head and neck. DESIGN Two prospective, double-blind, placebo-controlled phase III trials of identical design. Crossover from blinded to open-label phase was permitted for patients with disease progression. SETTING Tertiary referral centers in North America and Europe. PATIENTS One hundred seventy-nine intensively pretreated patients with recurrent or refractory squamous cell carcinoma of the head and neck. INTERVENTION Cisplatin/epinephrine injectable or placebo gel was administered by direct intratumoral injection; up to 6 weekly treatments. Dose was 0.25 mL of active or placebo gel per cubic centimeter of tumor up to 10 mL total. Patient benefit after local tumor control of the most symptomatic tumor was assessed by patients and physicians using the Treatment Goals Questionnaire. MAIN OUTCOME MEASURES Local tumor response and patient benefit attributable to improvements in tumor-related symptoms. RESULTS Combined results for the 178 patients with evaluable data in the 2 trials confirmed objective tumor responses in 35 (29%) of 119 patients, including 23 (19%) complete responses achieved with cisplatin/epinephrine gel, vs 1 (2%) of 59 for placebo (P<.001). Tumor response and patient benefit were significantly correlated (P=.006): 47% (17/36) of patients with target tumor responses achieved a rigorously defined benefit based on a prospectively selected treatment goal vs 15% (22/142) of nonresponders. CONCLUSION Cisplatin/epinephrine injectable gel reduces tumor burden, ameliorates tumor symptoms, and provides a new therapeutic option for treating patients with squamous cell carcinoma of the head and neck.

Abstract
OBJECTIVE To determine whether chemoradiation (CX) is as effective as surgery with postoperative radiotherapy (SX) for operable, locally advanced head and neck cancer (LAHNC). METHODS A retrospective review of 78 patients with operable stage III or IV cancer of the upper aerodigestive tract who were treated by CX (n = 25) or SX (n = 53) during a 20-year period was undertaken. RESULTS Fewer patients relapsed regionally when treated by SX than by CX (p = 0.006). On the other hand, there was no significant difference in local recurrence, distant metastasis, 2-year survival rate, or 5-year survival rate between the two patient groups. CONCLUSION Our results suggesting that CX is not as effective as SX for patients with operable LAHNC calls for a randomized trial comparing CX to SX in such cases.

Abstract
OBJECTIVE We sought to determine whether induction chemotherapy followed by concomitant chemoradiation (ICCR)-induced advanced neck disease regression could predict outcome, especially the need for complete neck dissection in patients with N2-3 stage IV head and neck cancer (HNC). METHODS A retrospective study of 339 patients evaluated for treatment of stage IV HNC during the years 1988 to 1997 revealed 36 individuals with N2-3 cervical lymphadenopathy who were treated with ICCR. Responses to treatment, patterns of failure, and survival rates were analyzed. RESULTS Primary and regional tumor regressions were complete in 21 patients (58%), partial in 9 (25%), and absent in 6 (17%); the corresponding local failure rates were 5%, 44%, and 33% (P < 0.02). The regional failure rates were 24%, 89%, and 83%, respectively (P < 0.001); distant failure rates were 10%, 0%, and 0% (P > 0.99). The estimated 2-year survival rates for complete and partial/nonresponders were 57% and 20%, respectively (P < 0.02). CONCLUSION Patients with advanced regional metastases of HNC who respond completely to ICCR have an excellent chance for survival. However, such ICCR-induced complete regression of regional tumor cannot reliably predict ultimate neck disease control.

Abstract
The role of maintenance therapy in multiple myeloma is controversial. Recent studies have shown an improvement in both progression-free and overall survival for patients receiving maintenance treatment with a combination of interferon and glucocorticoids, compared with interferon alone. The role of glucocorticoids alone as maintenance therapy has not been previously addressed. We compared alternate-day, oral prednisone at 2 different dose levels (10 mg versus 50 mg) for remission maintenance among previously untreated myeloma patients following a response to induction with standard-dose vincristine, doxorubicin, and dexamethasone with prednisone (VAD-P) or VAD-P plus quinine (VAD-P/Q). There were 250 eligible patients registered on Southwest Oncology Group study 9210 and randomized to receive VAD-P or VAD-P/Q. There were 125 patients achieving at least a 25% tumor reduction following induction therapy who were randomized to either physiologic (10 mg) or pharmacologic (50 mg) doses of alternate-day, oral prednisone until disease progression. At the time of study entry, patient characteristics were similar in VAD-P and VAD-P/Q patients and in the 2 arms randomized to maintenance therapy. After a median follow-up of 53 months, there was no difference in either progression-free or overall survival between the 2 induction regimens. However, from the time of maintenance randomization, both progression-free (14 versus 5 months; P =.003) and overall survival (37 versus 26 months; P =.05) were significantly improved in patients receiving 50 mg as compared with 10 mg alternate-day prednisone. There was no difference in treatment-related adverse events between the groups. Thus, 50 mg, oral, alternate-day prednisone is effective maintenance treatment for multiple myeloma patients who achieve a response to induction chemotherapy. (Blood. 2002;99:3163-3168)

Abstract
A phase II trial of gemcitabine (Gemzar), a nucleoside analogue with broad activity in solid tumors, was performed in patients with recurrent or metastatic squamous cell carcinoma of the head and neck. A total of 26 eligible patients were registered to receive a dose of 1250 mg/m2 weekly for 3 weeks, followed by a 1 week rest. Toxicity was evaluable in 26 patients. Nausea and vomiting occured in 11 and 6 patients, repectively. Grade 3 or 4 hematologic toxicities were infrequent. Two patients developed neutropenic infections. One patient developed fatal liver failure which was thought due to progressive liver metastases or infection 14 days after a single dose of gemcitabine. There were no objective treatment responses (95% CI 0-13%), with a median survival of 6 months in this highly resistant disease population. Gemcitabine is not considered active enough as monotherapy for further evaluation in this disease population.

Abstract
PURPOSE To determine the incidence and treatment outcome of compression of the cauda equina by metastatic disease in patients with breast cancer. METHODS A retrospective study of individuals diagnosed with breast cancer at a single institution during a 16-year period was undertaken. RESULTS Of the 1,283 patients studied, 15 (1.2%) developed cauda equina syndrome from metastatic disease. The median survival was eight months; ten (67%) survived for at least six months. Among the evaluable patients, pain was completely relieved in eight of ten women; complete resolution of neurologic deficits was observed in five of nine patients. CONCLUSION Metastatic breast cancer compression of the cauda equina and long-term survival of patients are infrequent occurrences. Beneficial responses can be mediated by radiotherapy.

Abstract
Malignant melanoma is rapidly increasing in the United States. Metastatic disease responds poorly to currently available chemotherapy. Pyrazine diazohydroxide (PZDH) is a new agent inhibiting DNA synthesis that is active in mouse tumor models and human xenografts and lacks cross resistance with multiple standard agents. In this phase II trial, patients with no prior chemotherapy or immunotherapy for metastatic disease and performance status (SWOG) of 0-1, were treated with pyrazine diazohydroxide at a dose of 100 mg/m2/day by i.v. bolus injection over 5-15 minutes for 5 consecutive days every 6 weeks. There were 23 eligible patients entered on this trial with 74% having PS of 0 and 91% having visceral metastases. There were no confirmed anti-tumor responses. The overall response rate is 0% (95% CI 0%-15%). Median overall survival is six months (95% CI 5-8 months). The most common toxicities were hematologic and consisted of lymphopenia, thrombocytopenia, anemia, and leukopenia. Fatigue. and nausea and vomiting were the next most common toxicities. Pyrazine diazohydroxide by this dose and schedule has insufficient activity in the treatment of disseminated malignant melanoma to warrant further investigation.

Abstract
BACKGROUND The combination of oral estramustine and oral etoposide has generated response rates of 40-50% in patients with hormone refractory prostate cancer in single institution trials. This study tested this regimen in a multi-institutional setting. METHODS Fifty-five patients were accrued over a period of 4 months between 1 March 1996 and 1 July 1996. Two patients were not analyzable and two patients were ineligible. They were given an oral regimen consisting of estramustine 15 mg/kg/day (capped at 1120 mg per day) and etoposide 50 mg/M(2)/day, days 1-21 every 28 days. Patients received a median of two cycles of therapy. RESULTS Toxicities included 11 patients (20%) with grades 3 or 4 granulocytopenia, 5 patients (10%) with grades 3 or 4 edema, and 3 patients (6%) with a thrombotic event. There were two treatment-related deaths, one as a result of anemia and the other as a result of a myocardial infarction. Of the 32 men who received at least 2 cycles of therapy, 7 men (22%) demonstrated a partial response to this regimen as measured by prostate-specific antigen (PSA) criteria of a 50% decline from pretreatment values. CONCLUSIONS This trial demonstrates the toxicity of estramustine delivered in high dose. It also illustrates the difficulty of conducting phase II trials in prostate cancer in the cooperative group setting where the experience and comfort level of oncologists with new agents is less than that of the physicians at the institution where the therapy was developed. As the activity of this regimen with low-dose estramustine is defined, further multi-institutional studies may be warranted.

Abstract
PURPOSE Two phase II studies were conducted to evaluate infusional cyclophosphamide, doxorubicin, vincristine, and dexamethasone chemotherapy, termed the CVAD regimen, alone (Southwest Oncology Group [SWOG] 9240) and with the chemosensitizers verapamil and quinine (SWOG 9125) to assess effects on response, survival, and toxicity in intermediate- and high-grade advanced-stage non-Hodgkin's lymphoma (NHL). The results were compared with the historic group of patients randomized to CHOP chemotherapy on Intergroup (INT) 0067 (SWOG 8516). PATIENTS AND METHODS All patients had biopsy-proven intermediate- or high-grade NHL (lymphoblastic histology excluded), were ambulatory and previously untreated, and had bulky stage II, III, or IV disease. One hundred twelve patients were registered on SWOG 9240 and received cyclophosphamide 750 mg/m(2) by intravenous bolus day 1, doxorubicin 12.5 mg/m(2)/d and vincristine 0.5 mg/d delivered as a continuous 96-hour infusion on days 1 through 4, and dexamethasone 40 mg/d orally on days 1 through 4 (CVAD). Cycles were repeated every 21 days for eight cycles. One hundred patients on SWOG 9125 received the same chemotherapy and the chemosensitizers verapamil 240 mg bid and quinine 40 mg tid. Chemosensitizers were begun 24 hours before chemotherapy and continued for a total of 6 days. RESULTS Eighty-one patients were eligible for each study. The complete response (CR) rates were 39% on SWOG 9125 and 31% on SWOG 9240. With a median follow-up of 5.8 years on SWOG 9125 and 4.5 years on SWOG 9240, the 2-year failure-free survival (FFS) rate was 42% on SWOG 9125 and 41% on SWOG 9240. Two-year overall survival (OS) rate was 64% on SWOG 9125 and 58% on SWOG 9240. These results are comparable to a 44% CR rate, a 2-year FFS of 46%, and 2-year OS of 63% observed in 225 patients treated with CHOP on INT 0067 (SWOG 8516). CONCLUSION CVAD combination chemotherapy alone or with the chemosensitizers verapamil and quinine is not promising therapy with respect to improved response or OS in intermediate- and high-grade advanced-stage NHL.

Abstract
PURPOSE Few studies have described the effects of aggressive combined therapy for locally extensive head and neck cancer in the elderly. Our study evaluated the outcome of this particular cohort of patients after such treatments. METHODS Survival, failure, morbidity, and complication rates were determined retrospectively in 43 elderly patients with stage III or IV head and neck cancer who underwent curative surgery and postoperative radiotherapy (n = 33) or neoadjuvant, 3-drug chemotherapy plus radiotherapy (n = 10) between the years 1977 and 1992. RESULTS The crude survival rate at 3 years was 27% in patients managed by surgery plus radiotherapy, and 30% in individuals treated with chemoradiation; the corresponding locoregional failure rates were 23% and 30%; and the distant failure rates were 13% and 0%, respectively. The acute toxicity rate was 12% in the surgery plus radiotherapy group and 30% in the chemoradiation patients; the corresponding late complication rates were 0% and 10%. There were no toxic deaths. CONCLUSION Radical combined treatments can be performed safely and achieve long-term, disease-free survival in selected elderly patients with locally extensive head and neck cancer.

Abstract
PURPOSE To evaluate the effects in women of the timing of breast irradiation (BI) in relation to the application or non-application of adjuvant chemotherapy after breast conservation surgery (BCS) for early stage cancer. METHODS Between October 1981 and June 1995, 47 women with stage I and II breast cancer underwent BCS. Twenty-six patients did not receive adjuvant chemotherapy (NAC) and 21 women did (AC). In the NAC group, BI commenced within (n = 9) or after (n = 17) seven weeks following BCS; in the AC group, 18 women received BI more than 24 weeks after BCS and three patients within 24 weeks. RESULTS In the NAC group, there was a trend toward more local and systemic failures plus a definite correlation with poorer survival (p = 0.05) when BI was initiated more than 7 weeks after BCS. In the AC group, the locoregional and systemic failures occurred only in women with a delay of BI exceeding 24 weeks; survival was not different between the subgroups. CONCLUSION An undue delay of BI should be avoided in patients after BCS whether they require adjuvant chemotherapy for early stage breast cancer or not.

Abstract
PURPOSE A retrospective study was conducted to determine the importance of the interval between diagnosis of brain metastasis (BRM) and cranial irradiation (CI). METHODS The charts of 92 patients with a known diagnosis of cancer and suspected BRM as shown on radioimaging studies were reviewed retrospectively. The median interval between diagnosis and the onset of CI for BRM was five days; one group of 48 individuals received CI within an interval of five days, and another group of 44 patients after an interval of five days. Symptom palliation, objective responses to CI and survival were evaluated in both groups. RESULTS Neither symptomatic and objective responses to treatment nor overall survival differed significantly between the patient groups. CONCLUSION These observations suggest that while CI is beneficial to most patients with BRM, its timing after the diagnosis of BRM may not seriously affect patient outcome.

Abstract
A 64-year-old man with metastatic multiple myeloma in the thigh was treated with radiation therapy. After a total dose of 30 Gy/10 fractions, significant resolution of the tumor in the thigh was observed. This case confirms the accepted dictum that multiple myeloma is a radioresponsive neoplastic disorder.

Abstract
A retrospective review of 8 years of treatment in 2 hospitals in Shreveport showed that neoadjuvant chemotherapy with radiotherapy was performed in 39 patients with inoperable, locally advanced head and neck cancer. Twenty-two individuals treated by definitive radiotherapy alone served as historical controls. The cumulative survival rate at 4 years was 34% in patients managed by neoadjuvant chemotherapy with radiotherapy and 7% in patients treated by radiotherapy only. With the exception of greater acute toxicity seen in patients receiving neoadjuvant chemotherapy with radiotherapy, differences in locoregional failure, distant metastasis, and late complication rates were not observed between the patient groups.

Abstract
Activation of CD28 on T lymphocytes initiates a cascade of intracellular events, which in concert with activation of the T cell receptor, culminates in production of cytokines and a functional immune response. One of the earliest biochemical changes observed following stimulation of CD28 is tyrosine phosphorylation. We have demonstrated that both the LCK and the EMT/ITK/TSK (EMT) intracellular tyrosine kinases are activated following cross-linking of CD28. Utilizing somatic cell mutants lacking LCK, we demonstrate that functional LCK is required for CD28-induced activation of EMT as evidenced by increased tyrosine phosphorylation and kinase activity. In support of a role for LCK in EMT activation, reconstitution of a LCK-negative Jurkat T cell line by transfection with normal LCK recreates CD28-mediated EMT activation. Furthermore, co-transfection of LCK and EMT into COS-7 cells showed that EMT becomes phosphorylated in the presence of LCK. In addition, increases in EMT association with CD28 were eliminated in a LCK-negative Jurkat cell line, but were restored following transfection of wild type LCK. The data are most compatible with a model in which LCK, either directly or indirectly, initiates EMT activation and association with CD28 following ligation of CD28.
