Higher capecitabine AUC in elderly patients with advanced colorectal cancer (SWOGS0030). Br J Cancer 2013; 109:1744-9. [PMID: 24022189 PMCID: PMC3790171 DOI: 10.1038/bjc.2013.517] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2012] [Revised: 08/07/2013] [Accepted: 08/09/2013] [Indexed: 12/15/2022] Open
Abstract
Background: The aging process is accompanied by physiological changes including reduced glomerular filtration and hepatic function, as well as changes in gastric secretions. To investigate what effect would aging have on the disposition of capecitabine and its metabolites, the pharmacokinetics between patients ⩾70 years and <60 years were compared in SWOG0030. Methods: Twenty-nine unresectable colorectal cancer patients were stratified to either ⩾70 or <60 years of age, where the disposition of capecitabine and its metabolites were compared. Results: Notable increase in capecitabine area under the curve (AUC) was accompanied by reduction in capecitabine clearance in ⩾70 years patients (P<0.05). No difference in 5'-deoxy-5-fluorocytidine, 5'-deoxy-5-fluorouridine (DFUR), and 5-fluorouracil (5FU) AUCs between the two age groups, suggesting that carboxylesterase and cytidine deaminase (CDA) activity was similar between the two age groups. These results suggest that metabolic enzymes involved in converting capecitabine metabolites are not altered by age. An elevation in capecitabine Cmax and reduction in clearance was seen in females, where capecitabine AUC was 40.3% higher in women. Elevation of DFUR Cmax (45%) and AUC (46%) (P<0.05) was also noted, suggesting that CDA activity may be higher in females. Conclusion: Increases in capecitabine Cmax and AUC was observed in patients ⩾70 years when compared with younger patients who were >60 years.

Abstract
2 Background: Preoperative platinum-based CRT for operable esophageal cancer has improved overall survival (OS) compared to surgery alone. The phase II SWOG 0356 trial designed to test oxaliplatin (OXP) plus infusion 5-fluorouracil (5-FU) and external beam radiation prior to surgery for potentially curable EA has produced promising centrally confirmed complete pathologic response (pCR) rate (28.3%). After surgery patients were given a second cycle of OXP and 5FU. 2-year OS was 54.2%. However, treatment efficacy may be significantly compromised as a result of interindividual variations. We tested whether intratumoral GE levels in drug metabolism (DPD, GSTPi, TS and TP) and DNA repair (ERCC1 and XPD) predicted clinical outcome (CO). We also tested whether specific pattern of 12 polymorphisms in 8 genes (drug metabolism (GSTP, MTHFR and TS) and DNA repair (ERCC1, RAD51, XPD, XRCC1 and XRCC3)) predicted CO. Methods: A total of 90 patients from the SWOG 0356 study were eligible for the molecular correlative study. mRNA was extracted from laser-capture-microdissected tumor tissue. After cDNA was prepared by reverse transcription, quantitation of the candidate genes and an internal reference gene (ß-actin) was performed using a fluorescence-based real-time detection method (TaqMan). Established GE cutoffs were tested (ERCC1 <1.7 x 10-3; TS <4.0 x 10-3). DNA was extracted from blood and genotyped using PCR-RFLP techniques. Results: In univariate analysis, we found ERCC1 GE levels to be significantly associated with progression-free survival (PFS) and OS. Patients with high ERCC1 GE levels had worse 2-year PFS (17 vs 67%, p=0.004) and 2-year OS (37 vs 72%, p=0.04) compared to low GE levels. ERCC1 GE levels were not associated with pCR. All the other GE levels tested did not show significant association with CO. None of the tested polymorphisms showed any association with CO. Conclusions: Our data suggest that GE levels of ERCC1 may help to identify patients with stage II-III EA likely to experience longer survival when treated with preoperative OXP-based CRT. No significant financial relationships to disclose.

Oxaliplatin (OXP) plus protracted infusion 5-fluorouracil (PIFU) and external beam radiation (EBRT) prior to surgery (S) for potentially curable esophageal adenocarcinoma (EA): A Southwest Oncology Group (SWOG) phase II trial with molecular correlates (S0356).

Abstract
4513 Background: Although neoadjuvant combined modality therapy (NACMTX) has become a standard of care in the United States, median overall survival (OS) for patients (PTS) with EA has changed little over the past 25 years. Progression free survival (PFS) and OS after NACMTX depend on extent of primary tumor response. New regimens to increase pathologic complete response (pCR) are needed. Based on phase I data, SWOG designed a phase II trial (S0356) to test OXP with PI5FU and EBRT for PTS with EA. Objectives included pCR rate ≥ 25%, acceptable toxicity (TOX), PFS, OS and exploration of molecular parameters relevant to pCR. Methods: Eligibility: clinical stage II/III EA, ≥ 18 years, Zubrod PS ≤ 2, standard hematologic/non-hematologic values, and tumor < 2 cm into the gastric cardia. OXP 85 mg/m2 was given day (d) 1, 15 and 29; PI5FU 180 mg/m2/d was given d 8-d43. EBRT 180 cGy/d started d 8 x 25 fractions, 5 d/week to total dose 4500 cGy. S was planned 2–4 weeks after NACMTX, with a second cycle of OXP/ PI5FU after S. Central pathology review of surgical specimens was mandated. The trial used a 2-stage design; the trial was halted at 45 PTS to review pCR rate; it reopened to full accrual. Results: 98 PTS enrolled between 9/15/04 and 8/18/08. 6 PTS were ineligible; 2 PTS did not receive therapy (TX). 90 PTS, 84 men (93%), median age 61.7 years, were analyzed. 4 deaths (4.5%) were due to protocol TX; 2 due to NACMTX, 2 to S. 43% and 18% of PTS had grade 3/4 toxicity, respectively: 39% GI, 22% flu-like/fatigue, 17% pulmonary, 16% hematologic, 14% mucositis and 3% neurologic. 77 PTS (86%) underwent S. 30 PTS (33%) had pCR. 9 PTS (10%) had in-situ cancer or T1N0M0. <50% received postoperative CTX. Conclusions: OXP, PI5FU and EBRT for PTS with EA has produced the highest pCR rate reported to date for a cooperative group trial. Significant but manageable non-hematologic TOX was observed. S mortality is acceptable. Future trials built on this platform should plan to complete all TX before S. Tumor molecular profiles (analyses in progress) may predict benefit from this treatment. Data on PFS and OS will follow. [Table: see text]

Abstract
3598 The treatment for metastatic colorectal cancer has markedly improved but the disease is still not curable, and additional active agents need to be found. Depsipeptide is a histone deacetylase inhibitor that has shown activity against human solid tumor cell lines and promising results in murine model systems. This phase II trial was undertaken to determine its activity in patients with advanced colorectal cancer. Eligibility requirements included measurable disease, either metastatic or locally advanced and not surgically resectable, Zubrod performance status of 0–1, and adequate renal, hepatic, hematologic and cardiac function. Prior surgery or radiation therapy was allowed and patients were required to have received either one or two prior chemotherapy regimens for advanced disease. A two-stage design was used designed to detect a difference in the null hypothesis of 5% response vs. an alternative 20% response, with 20 eligible patients to be accrued initially followed by an additional 20 patients if one or more confirmed responses were observed. The study closed after the first stage, with 28 patients registered. Three patients are ineligible, two who did not meet requirements for serum magnesium level, and one whose baseline labs were performed more than 14 days prior to registration. One eligible patient never received treatment and is not analyzable for any endpoint. For the 24 eligible and analyzable patients, median age was 58.6 years (range 31–84) with 14 males. Performance status was 0 in 16 patients and 1 in 8. Ten patients received 1 prior chemotherapy regimen and 14 received 2 prior regimens. There were no grade 4 or higher toxicities. The most common grade 2 or 3 toxicities were anorexia, fatigue, nausea, and dehydration. No objective responses were observed. Four patients had stable disease, 15 showed increasing disease, 3 had symptomatic deterioration, and 2 had assessment inadequate. The current Kaplan-Meier estimate of 6 month overall survival is 69% (95% CI 50%-88%) with a median survival of 8.4 months. Depsipeptide does not show significant anti-tumor activity in previously treated patients with advanced colorectal cancer. No significant financial relationships to disclose.

Abstract
PURPOSE Aggressive inpatient chemoimmunotherapy protocols for metastatic melanoma have yielded encouraging response rates but have required lengthy hospitalizations. To reduce or eliminate the need for hospitalization, we have developed an outpatient chemoimmunotherapy regimen and assessed its efficacy and toxicity in 53 patients treated at the University of Washington Medical Center. PATIENTS AND METHODS Eligible patients with measurable metastatic melanoma received carmustine (150 mg/m2 every 6-8 weeks) and dacarbazine (660 mg/m2) and cisplatin (75 mg/m2) every 3 to 4 weeks in an infusion center plus tamoxifen (20 mg/day). Patients self-administered subcutaneous recombinant interleukin-2 (rIL-2) at 3 MIU/m2/day on days 3 to 9, and recombinant interferon alfa-2a (rIFN-alpha 2a) at 3 MIU on day 3 and at 5 MIU/m2/day on days 5, 7, and 9. Maintenance rIFN-alpha 2a was self-administered subcutaneously at 5 MIU/m2 tiw for 12 months after complete or stable partial response. Response and survival were assessed. RESULTS Fifty-three patients (median age = 49 years) have received 181 cycles. To date, there have been 10 complete responses (19%) lasting 2 to 28+ months and 12 partial responses (23%) lasting 2 to 11 months, for an overall response rate of 42% (95% confidence interval, 28%-55%). The median overall survival was 12 months. Grade 3/4 vomiting occurred in 32% of cycles, but hospitalization for supplemental intravenous fluids was required in only 11% of cycles for a median of 3 days. Grade 4 thrombocytopenia and neutropenia occurred in 9% and 8% of cycles, respectively. Grade 3 renal dysfunction occurred in only one cycle and was reversible. CONCLUSION A chemoimmunotherapy regimen for patients with metastatic melanoma has been defined that is well tolerated on an outpatient basis and is associated with a median survival comparable to that with aggressive inpatient chemoimmunotherapy regimens.

Metastatic renal cell carcinoma: long-term survival after therapy with high-dose continuous-infusion interleukin-2. THE CANCER JOURNAL FROM SCIENTIFIC AMERICAN 1997; 3 Suppl 1:S85-91.

Abstract
PURPOSE This article undertakes to define the response rate, long-term survival, and toxicity in patients with metastatic renal cell carcinoma (MRCC) treated with high-dose continuous intravenous infusion (CIV) recombinant interleukin-2 (rIL-2) with or without lymphokine-activated killer (LAK) cells. PATIENTS AND METHODS One hundred twenty-three consecutive patients received CIV rIL-2 (18-22 MIU/m2/day on days 1-5, and 6-8 MIU/m2/day on days 10-19) on one of five sequential protocols at the University of Washington between 1988 and 1995. The first 76 patients received LAK cells. The median age was 55 years (range, 32-76 years), and 71% had undergone prior nephrectomy. RESULTS Nine patients achieved a complete response (7.3%) and 14 patients achieved a partial response (11.4%) for an overall response rate of 19% (95% confidence interval, 12%-26%). The median survival was 19 months, and the 5-year survival was 20%. Seven of nine complete responders (78%) remain in continuing complete response at 43+ to 109+ months. Intensive care unit and vasopressor support were required in 42% and 23% of patients, respectively, who received rIL-2 + LAK cells, and in 18% and 4% of those who received rIL-2 alone. There was one treatment-related death. CONCLUSION We report the largest single-institution experience and the longest survival for patients with MRCC treated with CIV rIL-2. The administration of rIL-2 by CIV is associated with less frequent intensive care unit and vasopressor support than with high-dose intravenous bolus regimens, and hence may enhance the therapeutic index in patients with MRCC.

Interleukin-12 induced cytolytic activity in lymphocytes from recipients of autologous and allogeneic stem cell transplants. Bone Marrow Transplant 1997; 19:867-73.

Abstract
Interleukin-12 (IL-12) has been reported to enhance the cytolytic activity of NK and activated T cells and to induce low levels of lymphokine-activated killer (LAK) activity in normal human lymphocytes. Therapy with IL-12 has induced tumor eradication in murine models. These observations suggest that IL-12 might have a role as treatment for minimal residual disease following transplantation. To determine whether PBL from recipients of autologous (autoSCT) and allogeneic (alloSCT) bone marrow or peripheral blood stem cell transplants respond to IL-12 with generation of LAK activity, PBL were incubated with IL-12 for 5 days, then tested in a 51Cr release assay for lysis of Daudi. PBL from 17 normal 'control' individuals were similarly tested and lysis was observed in only 3/17 (mean 16.9% of the three). By contrast, PBL from 10/12 patients obtained a median of 30 days after autoSCT, exhibited significant IL-12-induced LAK activity (mean lysis, 35.3%, P < 0.005 vs controls). PBL from 18 of 20 patients tested a median of 44 days after alloSCT also exhibited significant LAK activity (mean lysis, 30.0%, P < 0.005 vs controls). In autoSCT recipients, IL-12 and IL-2 at high concentrations (1000 U/ml each) were additive for induction of LAK activity, whereas low, suboptimal concentration of IL-12 (250 U/ml) and IL-2 (1 U/ml) were synergistic in 3/5 experiments. The percentage of PBL expressing IL-12 receptor beta 1 chain (IL-12r beta 1) was higher in stem cell recipients than in normal individuals, P < 0.05. Moreover, a higher percentage of IL-12r beta 1-positive PBL was associated with greater IL-12-induced LAK activity in transplant recipients. These studies demonstrate that PBL obtained early after stem cell transplantation have a higher percentage of cells expressing IL-12r beta 1 and respond to IL-12 with significantly greater LAK cytotoxicity than PBL from normal controls. These results suggest that IL-12 is a potentially attractive candidate for study as consolidative immunotherapy after stem cell transplantation.

Abstract
The prognosis for most patients with metastatic melanoma is poor, as the median survival is only 7 months. Phase II trials of chemoimmunotherapy have, however, reported response rates of 40% to 70% and prolonged disease-free survival in small subgroups of patients. Most chemoimmunotherapy trials have used high doses of recombinant interleukin-2 (rIL-2) and recombinant interferon alpha (rIFN-alpha) that produce significant toxicity and require prolonged hospitalization to manage side effects. To develop a treatment regimen for metastatic melanoma that would minimize costly hospitalization, we initiated a phase II trial of outpatient chemoimmunotherapy. Patients were treated with monthly cycles of intravenous carmustine, dacarbazine, cisplatin, and tamoxifen plus self-administered subcutaneous rIL-2 and rIFN-alpha as outpatients. To date, 32 patients have received 94 cycles of therapy. The most common toxicity was nausea and vomiting. Hospitalization for the management of toxicity was required in only seven cycles (7%). Thirty patients have been assessed for clinical response. The overall response rate was 43% (13% complete and 30% partial response). This phase II trial has established a tolerable regimen of outpatient chemoimmunotherapy, which has shown significant antitumor activity.

Paraneoplastic manifestations of renal cell carcinoma. Urol Oncol 1996; 14:216-22. [PMID: 8946620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/03/2023]
Abstract
Paraneoplastic manifestations are present in up to 20% of patients with renal cell carcinoma (RCC). There is convincing evidence that RCC tumor cells elaborate proteins that serve as mediators of endocrine (eg, ectopic production of parathyroid hormone-related protein or erythropoietin) as well as nonendocrine paraneoplastic syndromes. A paraneoplastic syndrome may be the initial clinical presentation of RCC in a significant number of patients, and recognition of these syndromes may facilitate early diagnosis. Most paraneoplastic syndromes associated with RCC remit after resection of the primary RCC or treatment of metastatic sites. The natural history of metastatic RCC is extremely variable. A significant proportion of patients may survive several years with slowly progressing metastatic disease. In these patients, the accurate diagnosis and management of paraneoplastic syndromes may be important in palliative management. Except for hypercalcemia, conventional medical therapies are seldom helpful. Other paraneoplastic manifestations of RCC include cachexia, fever, hepatic dysfunction, anemia, and amyloidosis, although our understanding of the underlying pathophysiology remains incomplete.

Abstract
Twenty-six patients with advanced cancer refractory to standard therapy were treated with recombinant human tumor necrosis factor (rTNF) in a study aimed at determining the toxicity and tolerance of rTNF and at seeking evidence of antitumor activity. The study design involved two treatments per week for 4 weeks with alternating subcutaneous and intravenous (IV) administration, and weekly dose escalation through four levels in each patient. The dose range was 1 to 200 micrograms/m2 for IV bolus injection, and 5 to 250 micrograms/m2 for subcutaneous injection. Thirteen patients completed the full course. Early discontinuation of treatment was related to rTNF toxicity in seven cases. The major side effects were rigors, fever, headache, fatigue, and hypotension. Acute changes in granulocyte, lymphocyte, and monocyte counts, changes in serum zinc levels and plasma cortisol levels consistent with an acute phase response, and inflammation at the site of subcutaneous injection were also seen. At doses of 125 to 250 micrograms/m2, inflammation at the subcutaneous injection site was unacceptably severe. Minor changes were seen in hemostatic parameters. Hypotension was corrected by fluid administration and did not require treatment with vasopressors. Initial serum concentrations of rTNF were measured at five minutes after IV administration and were found to range from 2.5 ng/mL after a dose of 35 micrograms/m2 to 80 ng/mL after a dose of 200 micrograms/m2. The half-life of rTNF in the blood was 20 minutes. A decrease in lymph node size was observed in a patient with B cell lymphoma.
