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.
