Abstract
BACKGROUND We conducted this trial to determine the maximum tolerated dose (MTD) of temsirolimus added to an established regimen comprised of rituximab and cladribine for the initial treatment of mantle cell lymphoma. PATIENTS AND METHODS A standard phase I cohort of three study design was utilized. The fixed doses of rituximab and cladribine were 375 mg/m(2) i.v. day 1 and 5 mg/m(2)/day i.v. days 1-5 of a 28-day cycle, respectively. There were five planned temsirolimus i.v. dose levels: 15 mg day 1; 25 mg day 1; 25 mg days 1 and 15; 25 mg days 1, 8 and 15; and 25 mg days 1, 8, 15, and 22. RESULTS Seventeen patients were treated: three each at levels 1-4 and five at dose level 5. The median age was 75 years (52-86 years). Mantle Cell International Prognostic Index (MIPI) scores were low in 6% (1), intermediate in 59% (10), and high in 35% (6) of patients. Five patients were treated at level 5 without dose limiting toxicity. Hematologic toxicity was frequent: grade 3 anemia in 12%, grade 3 thrombocytopenia in 41%, grade 4 thrombocytopenia in 24%, grade 3 neutropenia in 6%, and grade 4 neutropenia in 18% of patients. The overall response rate (ORR) was 94% with 53% complete response and 41% partial response. The median progression-free survival was 18.7 months. CONCLUSIONS Temsirolimus 25 mg i.v. weekly may be safely added to rituximab and cladribine at 375 mg/m(2) i.v. day 1 and 5 mg/m(2)/day i.v. days 1-5 of a 28-day cycle, respectively. This regimen had promising preliminary activity in an elderly cohort of patients with mantle cell lymphoma. CLINICALTRIALSGOV IDENTIFIER NCT00787969.

Abstract
4025 Background: Cumulative sNT is the dose-limiting toxicity of oxaliplatin which commonly leads to early discontinuation of oxaliplatin-based therapy in the palliative and adjuvant setting. We recently demonstrated the protective effect of CaMg against oxaliplatin-induced sNT as assessed by NCI-CTC (Nikcevich ASCO 2008). It is unclear, though, if CaMg reduced acute and/or chronic, cumulative sNT. Methods: 104 pts with colon cancer undergoing adjuvant therapy with FOLFOX were randomized to IV CaMg (1g calcium gluconate plus 1g magnesium sulfate pre- and post-oxaliplatin) or placebo (PL) in a double-blinded manner. NCI-CTC, an oxaliplatin-specific sNT scale and patient-reported outcome (PRO) questionnaires were used to differentially assess the effect of CaMg on acute (effect on sNT on days 1–4 after oxaliplatin) and chronic sNT (area between curves over whole course of therapy). Results: A total of 102 pts (50 CaMg, 52 PL; 96 mFOLFOX6, 6 FOLFOX4) were available for analysis. Apart from a strong reduction in muscle cramps with CaMg (p=0.002), no difference was found between CaMg and PL in PRO with regard to items reflecting acute sNT (e.g. sensitivity to cold, swallowing of cold liquids, throat discomfort) on days 1–4 after oxaliplatin of any treatment cycle. In contrast, CaMg was able to significantly reduce cumulative sNT in form of numbness in fingers (p=0.02), impaired ability to button shirts (p=0.05), tingling in fingers (p=0.06), and muscle cramps over the course of therapy (p=0.01). Conclusions: In our phase III, placebo-controlled trial, CaMg was able to significantly reduce chronic, cumulative sNT related to oxaliplatin as evaluated by specific PRO questionnaires. No effect was noted on phenomena associated with acute sNT. CaMg can be recommended as neuroprotectant against oxaliplatin-related chronic sNT, oxaliplatin's dose-limiting toxicity. [Table: see text]

Abstract #2109
Background: Despite the impressive results of the recently released trastuzumab adjuvant therapy trials, 15% of patients with HER2 overexpressing or amplified breast cancer developed tumor relapse at 4 years. Lapatinib is a small molecule reversible TKI that inhibits both ErbB1 and ErbB2. The current study was developed to assess the cardiac safety and feasibility of adding lapatinib to paclitaxel and trastuzumab following as part of adjuvant therapy.
 Methods: A single-arm phase II study of doxorubicin (A, 60 mg/m2 day 1) and cyclophosphamide (C, 600 mg/m2 day 1) [q2w or q3w for 4 cycles]; followed by paclitaxel (P, 80 mg/m2 days 1, 8, 15), trastuzumab (T, 4 mg/kg loading dose then 2 mg/kg days 1, 8, 15), and lapatinib (L, 1000 mg days 1-21) [12 weeks]; followed by T (6 mg/kg day 1) and L (1000 mg days 1-21) [40 weeks] was conducted. The primary endpoint was the incidence of congestive heart failure. The current unplanned safety analysis was undertaken due to the observance of a high rate of G3/4 diarrhea.
 Results: From April 2007 to June 2008, 98 pts were enrolled and initiated study treatment. Median age was 51 (range 32-72). Among 83 pts with adverse event (AE) data available, 50 (60%) pts have experienced a G3/4 non-hematologic AE. During post-AC treatment, among 53 pts with AE data available, 31 (58.5%) patients have experienced a G3/4 non-hematologic AE with 24 (45%) patients reporting G3/4 diarrhea. Median cycle of onset of G3/4 diarrhea was cycle 5 (first cycle of PTL) with 16 (64%) cases first reported during cycle 5 and 5 (20%) cases first reported during cycle 6. Among 57, 46, 38, and 32 pts receiving treatment with PTL during cycles 5-8, 65%, 57%, 61%, and 72% of patients received the full L dose, respectively. 31 patients have ended active treatment with 10 due to patient refusal and 8 due to adverse events.
 Conclusions: Preliminary data suggest that L given concurrently with P and T at a dose of 1000 mg per day induces an unacceptable rate of moderate to severe diarrhea. Careful monitoring of diarrhea as well as L dose reduction and initiation of loperamide at first occurrence of diarrhea are recommended. The dose of L when given concurrently with P and T has been amended to 750 mg per day in the current study and safety data for the 1000 mg and 750 mg per day cohorts will be presented. Implications for the ongoing ALTTO study will also be presented.

Abstract
8506 Background: A randomized study (Int J Rad Oncol Biol Phys 54:195–202, 2002) demonstrated a beneficial effect for octreotide in the treatment of diarrhea in patients receiving pelvic radiation therapy. This North Central Cancer Treatment Group study was undertaken to determine the effectiveness of depot octreotide in the prevention of diarrhea during pelvic radiation therapy. Methods: Patients receiving pelvic radiation therapy, with a planned minimum dose of 45 Gy at 1.70–2.1 Gy per day, were eligible for this study. The study was designed for a Wilcoxon test, with 112 evaluable patients, to have 85% power to detect a further one grade decrease in diarrhea over and above that experienced by patients treated with placebo. Between June 13, 2002 and October 28, 2005, 120 evaluable patients were randomly allocated, in double blind fashion, to receive octreotide (62 patients) or placebo (58 patients), prior to the fourth radiation therapy fraction. Octreotide dosing: Octreotide, 100 micrograms subcutaneously on day 1 followed by depot octreotide, 20 milligrams intramuscularly on days 2 and 29. Results: Grade 0, 1, 2 and 3 diarrhea was observed in 17%, 32%, 26% and 26% of patients treated with octreotide and 18%, 34%, 22%, and 26% of patients treated with placebo (P=0.86). Grade 0, 1, 2 and 3 tenesmus was observed in 55%, 30%, 11% and 4% of patients treated with octreotide and 76%, 16%, 4%, and 4% of patients treated with placebo (P=0.04). No other statistically significant differences in toxicity were observed. Conclusions: Octreotide, as administered in this study, did not decrease diarrhea during pelvic radiation therapy.

Abstract
17505 Background: A previous trial of 2-CDA as a single agent for therapy of mantle cell lymphoma demonstrated this agent to be efficacious with an overall response rate of 81% (31% complete responses) (Blood 1999 Nov 15; 94:660a). A phase II study of the addition of rituximab to 2-CDA was conducted by the North Central Cancer Treatment Group based on improved outcomes achieved by the addition of rituximab to other regimens active in MCL. Methods: This one-stage phase II study was designed to determine the complete response (CR) or complete response/unconfirmed (CRu) rate. Central pathology confirmation of cyclin D1 positive mantle cell lymphoma was required. No previous therapy for lymphoma was allowed, with the exception of splenectomy. The shedule was rituximab 375 mg/m2 IV day 1; 2-CDA 5 mg/m2/d IV days 1–5 of a 4-week cycle. After 2 of the first 6 patients developed grade 4 neutropenia, subsequent patients received either pegfilgrastim or filgrastim support. Patients received 2–6 cycles of therapy, depending on response. Patients were required to achieve at least a PR after 2 cycles of therapy to continue on protocol therapy. Results: Patient characteristics of all 29 eligible pts: median age: 70 (range: 41–86); 21 male, 8 female; PS 0 (55.2%), PS 1 (41.4%), PS 2 (3.5%); stage II (6.9%), stage III (3.5%), stage IV (89.7%); prior splenectomy (20.7%). The only grade 4 adverse event occurring more than once was neutropenia (20.7%). One patient died of cerebral ischemia in the setting of pneumonia without neutropenia. Response has been determined in 26 pts with 50.0% (95% CI: 30.0–70.0%) achieving a CR, none of whom have relapsed to date. Three patients progressed early at 17, 45, and 46 days, two of whom have died, and a fourth relapsed day 222. 10 pts (34.0%) went on to receive further therapy off study, 5 in less than a PR after 2 cycles, 2 in PR after study therapy, and 1 who went off study for a rash. At last contact, 26 (89.7%) were alive (median follow-up 10.7 months; range: 1–28). Conclusions: Rituximab and cladribine were well tolerated for the treatment of MCL in a group including elderly patients. The response rate may have been underestimated due to the study design, which required at least a PR after 2 cycles to continue therapy. Despite this, 50% achieved a complete remission.

Abstract
The authors conducted a phase II study of somatostatin analogue in 18 patients with extensive stage small cell lung cancer (four with previous treatment, 14 without previous treatment). Patients received 2,000 mg subcutaneously thrice daily. They were required to have an Eastern Cooperative Oncology Group performance score of 0-2 and acceptable pretreatment biochemical parameters. No patient responded to treatment. The median time to progression was 44 days. The median survival was 106 days. Toxicity related to treatment consisted of mild diarrhea and anorexia. Somatostatin analogue is not active as a single agent in the treatment of extensive-stage small cell lung cancer.

Abstract
PURPOSE A minority of cancer survivors develops long-term postsurgical neuropathic pain. Based on evidence that capsaicin, the pungent ingredient in hot chili peppers, might be useful for treating neuropathic pain, we developed the present clinical trial. PATIENTS AND METHODS Ninety-nine assessable patients with postsurgical neuropathic pain were entered onto this study. After stratification, patients were to receive 8 weeks of a 0.075% capsaicin cream followed by 8 weeks of an identical-appearing placebo cream, or vice versa. A capsaicin/placebo cream was to be applied to the painful site four times daily. Treatment evaluation was performed by patient-completed weekly questionnaires. RESULTS During the first 8-week study period, the capsaicin-cream arm was associated with substantially more skin burning, skin redness, and coughing (P < .0001 for each). Nonetheless, treatment was stopped for patient refusal or toxicity just as often while patients were receiving the placebo as compared with the capsaicin. The capsaicin cream arm had substantially more pain relief (P = .01) after the first 8 weeks, with an average pain reduction of 53% versus 17%. On completion of the 16-week study period, patients were asked which treatment period was most beneficial. Of the responding patients, 60% chose the capsaicin arm, 18% chose the placebo arm, and 22% chose neither (P = .001). CONCLUSION A topical capsaicin cream decreases postsurgical neuropathic pain and, despite some toxicities, is preferred by patients over a placebo by a three-to-one margin among those expressing a preference.

Abstract
PURPOSE To evaluate the objective tumor response rate and toxicities of patients with metastatic colorectal carcinoma treated with irinotecan hydrochloride (CPT-11). PATIENTS AND METHODS A total of 121 patients with advanced colorectal carcinoma--90 with prior fluorouracil (5-FU) exposure and 31 chemotherapeutically naive patients--were enrolled between May 1993 and June 1994. Patients were treated with CPT-11 at 125 mg/m2 intravenously weekly for 4 weeks followed by a 2-week rest. RESULTS Among 90 patients with prior 5-FU chemotherapy, 12 partial responses were observed (response rate, 13.3%; 95% confidence interval [CI], 7.1% to 22.1%). Among 31 chemotherapy-naive patients, eight had partial responses (response rate, 25.8%; 95% CI, 11.9% to 44.6%). The median response duration as measured from time of initial treatment for the two groups was 7.7 months and 7.6 months, respectively. The major adverse reactions were gastrointestinal and hematologic. The incidence of grade 3 or 4 diarrhea was 36.4%, while the overall incidence of grade 3 or 4 leukopenia was 21.5% of patients. Only four of 121 patients (3.3%) developed neutropenic fever (grade 4 neutropenia with > or = grade 2 fever). The incidence of grade 4 leukopenia was higher in patients with prior pelvic radiotherapy (chi2 test P = .04), while the incidence of grade 3 or 4 diarrhea demonstrated no association with previous pelvic irradiation. CONCLUSION According to the study design, CPT-11 showed promising activity in chemotherapy-naive patients with advanced colorectal carcinoma and modest activity in patients with prior 5-FU exposure. The toxicity with this schedule appears manageable with appropriate dose modification for individual patient tolerance and an intensive loperamide regimen for the management of diarrhea. Care should be taken when treating patients with prior pelvic radiotherapy because of the increased risk of neutropenia.

Abstract
BACKGROUND This clinical trial was developed to determine whether ocular ice pack therapy would decrease 5-fluorouracil (5-FU)-induced ocular toxicity. METHODS Sixty-two patients who suffered from 5-FU-induced ocular toxicity, and were scheduled to receive another cycle of the chemotherapy that caused the ocular toxicity, were entered in this clinical trial. A randomized, crossover design was used, with patients documenting their ocular toxicity by the use of daily diaries. RESULTS The results from the first cycle of treatment suggested that ocular ice pack therapy decreased 5-FU-induced ocular toxicity (P = 0.056). The 38 evaluable patients in the crossover analyses demonstrated decreased ocular toxicity with ocular ice pack therapy (p = .001). The ocular ice pack therapy was well tolerated by most of the study participants. CONCLUSION Ocular ice pack therapy appears to lessen 5-FU-induced ocular toxicity to a clinically moderate degree. Better methods for decreasing 5-FU-induced ocular toxicity are necessary.

Abstract
The effects of low-dose estrogen oral contraceptives (OC) on the elimination of the oxidized benzodiazepines triazolam (TRZ) and alprazolam (ALP) and the conjugated benzodiazepines temazepam (TMZ) and lorazepam (LOR) were studied in two parallel crossover studies of 20 women each. Women taking OC steroids containing low doses of estrogen and women matched for age, weight, and cigarette smoking received single oral doses of TRZ (0.5 mg) and TMZ (30 mg) or ALP (1 mg) and LOR (2 mg). Kinetics were determined as plasma concentrations during 48 hr after dosing. OCs inhibited the metabolism of ALP: The AUC increased and the elimination rate constant was greater in users of OCs. For TRZ, which has an intermediate extraction ratio, the AUC was increased by OCs but not significantly so. In contrast, OCs decreased the AUC for TMZ and the elimination rate constants for LOR and TMZ. The AUC of LOR was not affected by OCs. Low-dose estrogen OCs may therefore inhibit the metabolism of some oxidized benzodiazepines and accelerate the metabolism of some conjugated benzodiazepines.
