PURPOSE To evaluate the infertility rate in patients with germ cell tumors receiving chemotherapy with cisplatin, etoposide (VP-16), and bleomycin (PVP16B). PATIENTS AND METHODS Thirty patients were evaluated. All patients had undergone chemotherapy with two to four cycles of PVP16B. A single semen analysis was performed 24 to 78 months following initiation of chemotherapy. All 30 patients were continuously disease-free. Eight of these patients had also undergone nerve-sparing retroperitoneal lymph node dissection (RPLND). RESULTS The median sperm concentration was 33.9 x 10(6), with a median volume of 3.2 mL. The median total sperm count was 86.4 x 10(6). Oligospermia (< 40 x 10(6) total sperm count) was found in 13 patients (43%), including six (20%) who were azoospermic. There was a high incidence of morphologically abnormal sperm, with only one patient having more than 50% normal spermatozoa. Only 13 patients (43%) had sperm motility greater than 50%. Five patients had positive semen antisperm immunoglobulin G (IgG). Eight patients fathered children, including three with document oligospermia. CONCLUSION Patients with germ cell tumors successfully treated with PVP16B chemotherapy are at substantial risk for persistent semen abnormalities. However, some patients with oligospermia will slowly recover and others are still capable of reproductive capacity despite continued oligospermia.

PURPOSE AND METHODS Between December 1984 and August 1992, 423 patients with newly diagnosed Hodgkin's disease (HD) were entered onto a randomized clinical trial that compared the regimen of mechlorethamine, vinblastine, procarbazine, and prednisone (MVPP) with a doxorubicin-containing hybrid regimen (chlorambucil, vinblastine, procarbazine, and prednisone/etoposide, vincristine, and doxorubicin [ChlVPP/EVA]). Median age for the group was 29.5 years (range, 15.2 to 68.8), and 52% had bulk disease. RESULTS After chemotherapy, patients in the hybrid arm of the trial had a higher complete remission (CR) rate (68.1% v 55.3%) and a lower failure rate (2.4% v 12.5%) than those in the MVPP arm. There were also fewer deaths during treatment in the hybrid arm of the trial (five v 13). With a median follow-up period for survivors of 4.5 years (range, 0 to 9), actuarial 5-year progression-free survival (PFS) for all cases is 80% in the hybrid arm and 66% in the MVPP arm (P = .005). A nonsignificant trend toward a better overall survival in the hybrid arm of the trial has also been identified. CONCLUSION These results suggest that ChlVPP/EVA hybrid is superior to MVPP in the treatment of HD. It has therefore been adopted as standard first-line therapy at the two centers.
Infectious and immunosuppressive complications of purine analog therapy.
Authors: Cheson B D 
Published: February 2017

PURPOSE The purine analogs fludarabine, cladribine, and pentostatin are active agents in the treatment of indolent lymphoid malignancies. This report reviews the pattern, severity, and consequences of the immunosuppression and myelotoxicity associated with these agents. METHODS The literature was searched using MedLine and Cancerline, as well as the bibliographies of published reports through the winter of 1994 and 1995. RESULTS Each of these drugs induces profound lymphocytopenia. A marked decrease in CD4 cells may persist for several years, while other mononuclear-cell populations recover more rapidly. The spectrum of infections encountered in these patients appears to be altered to include a wide range of opportunistic organisms. Factors that increase the risk of these infections include concurrent corticosteroids, extensive prior therapy, particularly with another purine analog, and poor response to purine analog treatment. CONCLUSION Because of the frequency of life-threatening infections with unusual pathogens that may occur in patients treated with purine analogs, aggressive and early diagnostic evaluation and appropriate use of myeloid growth factors may be necessary to ensure appropriate antimicrobial therapy.

PURPOSE Bone metastases are a major cause of morbidity in breast cancer, resulting in complications that include pain, loss of mobility, pathologic fracture, and tumor-induced hypercalcemia (TIH). Inhibition of osteoclast-mediated bone destruction using bisphosphonates represents a promising new management approach. PATIENTS AND METHODS Breast cancer patients with bone metastases were randomly allocated to receive chemotherapy alone (152 patients) or chemotherapy plus pamidronate 45 mg in 250 mL of saline as a 1-hour intravenous infusion every 3 weeks (143 patients). Whenever possible, treatment continued until progression of disease (PD) in bone appeared on radiographs or bone scan. Time to PD in bone and pain reduction according to a self-assessment six-point scale were selected as primary end points. PD in bone was verified during extramural review (EMR) of all imaging studies by blinded observers, and these data were used as the main efficacy criterion. Analgesic intake, World Health Organization (WHO) performance status, and complications of bone metastases (radiotherapy, TIH, fractures, orthopedic surgery) were also compared in the two groups. RESULTS AND CONCLUSION At EMR, median time to PD in bone was increased by 48% in patients who received pamidronate (249 v 168 days; P = .02, Wilcoxon test). Marked pain relief, defined as a two-point decrease lasting for > or = 6 weeks, was reported by 44% of pamidronate patients and by 30% of controls (P = .025, chi 2 test). The infusions (median, nine per patient; range, 0 to 39) were well tolerated, with no major toxicities reported. Pamidronate by repeated infusion can significantly slow the progression of bone metastases and reduce attendant morbidity.

LBA4509 Background: Advanced GC is an incurable disease; new and less toxic treatments are needed. HER2 overexpression has been reported in 6–35% of stomach and gastroesophageal tumors. Trastuzumab (H; Herceptin), a monoclonal antibody against HER2, has shown survival benefits when given with CT in patients (pts) with HER2-positive early and metastatic breast cancer. The ToGA study is the first randomized, prospective, multicenter, phase III trial to study the efficacy and safety of H in HER2- positive GC. Methods: Pts with HER2-positive gastroesophageal and gastric adenocarcinoma (locally advanced, recurrent, or metastatic) were randomized to receive H+CT (5-fluorouracil or capecitabine and cisplatin) q3w for 6 cycles or CT alone. H was given until disease progression. The primary end point was overall survival (OS); secondary end points included overall response rate (ORR), progression-free survival, time to progression, duration of response, and safety. An interim analysis was planned at 75% of deaths and the Independent Data Monitoring Committee recommended releasing the data as the pre-specified boundary was exceeded and median follow-up of pts was 17.1 months. Results: Tumors from 3,807 pts were centrally tested for HER2 status: 22.1% were HER2 positive (abstract #4556). 594 pts were randomized 1:1 at sites in Europe, Latin America, and Asia. Baseline characteristics were well balanced across arms. Median OS was significantly improved with H+CT compared to CT alone: 13.5 vs. 11.1 months, respectively (p=0.0048; HR 0.74; 95% CI 0.60, 0.91). ORR was 47.3% in the H+CT arm and 34.5% in the CT arm (p=0.0017). Safety profiles were similar with no unexpected adverse events in the H+CT arm. There was no difference in symptomatic congestive heart failure between arms. Asymptomatic left ventricular ejection fraction decreases were reported in 4.6% of pts in the H+CT arm and 1.1% in the CT arm. Conclusions: This first randomized trial investigating anti-HER2 therapy in advanced GC showed that H+CT is superior to CT alone. The OS benefit indicates that H is a new, effective, and well-tolerated treatment for HER2-positive GC. [Table: see text]

LBA5019 Background: Bevacizumab (BEV) plus interferon alpha (IFN) demonstrated a superior objective response rate and progression-free survival (PFS) versus IFN monotherapy in renal cell carcinoma (RCC) patients in 2 phase III trials. The primary objective of CALGB 90206 was to compare overall survival (OS) for advanced RCC patients receiving BEV plus IFN or IFN alone. Methods: Patients with previously-untreated, metastatic RCC with a clear cell component and Karnofsky performance status of ≥ 70% were eligible. Patients were prospectively randomized to receive BEV (10 mg/kg intravenously every 2 weeks) plus IFN (9 million units subcutaneously three times weekly) or the same dose and schedule of IFN as monotherapy. Randomization was stratified by nephrectomy status and number of MSKCC adverse features. The primary endpoint was OS, defined as the time from randomization to death due to any cause. The trial was designed with 86% power to detect a hazard ratio (HR) of 0.76, assuming a two-sided type I error of 0.05. The primary analysis was an intent-to-treat approach using the stratified log-rank statistic, and the present analysis was based on the target number of 588 deaths. Results: Between October 2003 and July 2005, 732 patients were enrolled; 369 pts to BEV plus IFN and 363 pts to IFN monotherapy. The median duration of follow up among censored patients was 46.2 months (IQR=45.2–48.2). The median OS was 18.3 months (95% CI; 16.5–22.5) for BEV plus IFN and 17.4 months (95% CI; 14.4–20.0, unstratified log rank p = 0.097) for IFN monotherapy. The stratified HR was 0.86 (95% CI; 0.73–1.01) for BEV plus IFN compared to IFN (stratified log-rank p = 0.069). The median OS for BEV plus IFN versus IFN was 32.5 vs. 33.5 months (p = 0.524) for MSKCC good risk, 17.7 vs. 16.1 months (p = 0.174) for intermediate risk and 6.6 vs. 5.7 months (p = 0.245) for poor risk patients. The median PFS was 8.4 months vs. 4.9 months (p<0.0001). Fifty-three percent of patients received subsequent systemic therapy. Conclusions: The addition of BEV to IFN significantly improves the objective response rate and PFS versus IFN monotherapy. Overall survival favored the BEV plus IFN arm, not meeting pre-defined criteria for significance. [Table: see text]

CRA3507 Background: FOLFOX is standard adjuvant therapy for stage III CC. Adding Cmab to FOLFOX benefits pts with metastatic CC WT KRAS tumors. N0147 assessed the potential benefit of Cmab added to FOLFOX. Methods: 21-56 days following resection and informed consent, KRAS status was centrally determined. Pts with wtKRAS CC were randomized to 12 biweekly cycles of oxaliplatin 85 mg/m2 d1, with leucovorin 400 mg/m2, 5FU 400 mg/m2 bolus IV, then 46-hr IV 5FU 2,400 mg/m2 on d1-2 (mFOLFOX6), without (arm A) or with Cmab (arm D) 250 mg/m2 d1&8, with Cmab at 400 mg/m2, cycle 1, d1. Primary endpoint was 3-yr disease free survival (DFS). Secondary endpoints included overall survival (OS) and toxicity. Planned accrual of 2,070 wtKRAS pts provided 90% power to detect hazard ratio (HR) of 1.33 with 2-sided α=0.05; with interim analyses after 25%, 50%, and 75% of planned events. Results: 1,760 wtKRAS pts (Arm A-858, Arm D-902) were enrolled at the time of closure; median follow-up on 1,624 pts is 15.9 months. Trial closed to accrual when preplanned interim analysis after 50% of planned events demonstrated no benefit to addition of Cmab. 3-yr DFS favored FOLFOX alone (HR 1.18, 95% CI 0.92-1.52; p=0.33). No benefit of Cmab was observed in any subgroups assessed. Any grade ≥ 3 AE, diarrhea, and failure to complete 12 cycles was significantly increased in arm D. Increased toxicity and greater differences in all outcomes were observed in pts aged ≥ 70 ( Table ). Conclusions: In this randomized phase III trial the addition of Cmab to mFOLFOX6 was of no benefit for pts with resected stage III wtKRAS CC.

LBA1010 Background: Taxane-based chemotherapy (CT) improves progression-free survival (PFS) in patients (pts) with newly diagnosed HER2-negative metastatic BC (MBC). SU, an oral multitargeted tyrosine kinase inhibitor (MTKI), demonstrated antitumor activity in combination with D in a phase I/II study in pts with MBC. A randomized, open-label, multicenter phase III trial in pts with newly diagnosed ABC tested the hypothesis that addition of a MTKI to D improves PFS vs. D alone. Methods: Eligible pts (female; ≥18 yrs) had an ECOG PS ≤1, and newly diagnosed HER2-negative MBC or ABC. If (neo)adjuvant therapy included a taxane, relapse must have occurred ≥12 mos after CT. Pts were randomized (1:1) to treatment (tx) with D 75 mg/m2 iv on day 1 and SU 37.5 mg/day po from day 2–15 q3w (Schedule 2/1; Arm A), or to D 100 mg/m2 iv 1-hr infusion q3w (Arm B) that could be given until progression. If D was discontinued in Arm A for reasons other than progressive disease (PD), single-agent SU 37.5 mg daily was permitted until PD. Median, independently assessed, PFS (primary endpoint) was compared between tx arms using stratified and unstratified log-rank tests. Overall objective response rate (ORR), overall survival (OS), pt-reported outcomes, and safety were secondary endpoints. Results: As of the data cutoff (February 1, 2010), the ITT population comprised 593 pts (SU+D, n=296; D, n=297). The trial did not meet its primary endpoint of prolonging PFS based on the independent radiologic assessment or in prolonging OS. Baseline characteristics were well balanced. Median relative dose intensity (RDI) was 94.2% and 92.4% for SU+D, and 92.6% for D arms, respectively. Median PFS was 8.6 mos (95% CI 8.2–10.3) in the SU+D arm vs 8.3 mos (95% CI 7.7–9.6) for the D arm (HR 0.922). Median OS was 24.8 mos (95% CI 21.5–33.1) in SU+D arm vs 25.5 mos (95% CI 22.8–27.8) for D arm (HR 1.207). ORR was significantly better for SU+D (51%) vs. D (39%) (p=0.0018). Frequent all causality grade 3/4 adverse events (≥10%) were neutropenia (46%), hand–foot syndrome (17%), and fatigue (12%) in the SU+D arm and neutropenia (44%) in the D arm. Conclusions: Based on these data, SU+D is not a recommended treatment option for patients with newly diagnosed ABC. Strategies using antiangiogenic TKIs that increase RR but not OS may need to be revisited. [Table: see text]

LBA4519 Background: About 50% of pts with advanced UC are not eligible for cisplatin based CHT (“unfit”) due to impaired renal function, performance status (PS) or comorbidity. This is the first randomized phase II/III trial comparing two chemotherapy regimens in this pts group. Methods: The primary objective of the phase III part of this study was to compare the overall survival (OS) of CHT naïve pts with measurable disease and an impaired renal function (GFR<60 but >30 ml/min) and/or PS 2 who were randomized to receive either GC (G 1000 mg/m2 d1 and 8 and C AUC 4.5) q21 days or M-CAVI (M 30 mg/m2 d1 and 15 and 22, C AUC 4.5 d1 and VI 3 mg/m2 d1 and 15 and 22) q28 days. In order to detect an increase of 50% in median survival on GC compared to M-CAVI (13.5 versus 9 months) based on a two sided logrank test at error rates alpha=0.05 and beta=0.20, 225 pts were required. Secondary endpoints were overall response rate (ORR) and progression free survival (PFS). Results: 238 pts, 119 in each arm, were randomized between January 2001 and March 2008 by 29 institutions. The median follow-up is 4.5 years. Two pts were ineligible and two other pts never started treatment. Best ORRs (CR + PR) were 41.2% (36.1% confirmed response) on GC versus 30.3% (21.0% confirmed response) on M-CAVI (p = 0.08). Median OS was 9.3 months on GC and 8.1 months on M-CAVI (p = 0.64). There was no difference in PFS between the two arms (p = 0.78). OS, PFS and ORR were similar in each of the risk groups (reason unfit for cisplatin and Bajorin risk group). Severe acute toxicity (SAT) (death, grade 4 thrombocytopenia with bleeding, or grade 3/4 renal toxicity, neutropenic fever or mucositis) was observed in 9.3% of pts on GC (2 toxic deaths) and 21.2% on M-CAVI (4 toxic deaths). The most common grade 3/4 toxicities were leucopenia (44.9%, 46.6%), neutropenia (52.5%, 63.5%), febrile neutropenia (4.2%, 14.4%), thrombocytopenia (48.3%, 19.4%), and infection (11.8%, 12.7%) on GC and M-CAVI, respectively. Conclusions: There were no significant differences in efficacy between the two treatment groups. The incidence of SATs was slightly higher on M-CAVI. [Table: see text]

LBA8512 Background: Patients with hepatic metastases from primary melanoma have a median survival between 6 and 9 months. Few treatment strategies provide a meaningful impact on outcome. This report examines the efficacy of a minimally invasive regional therapy with melphalan (MEL) in patients with hepatic metastases from malignant melanoma. Methods: Between February 2006 and October 2009, 93 patients (M:F; 45:48) were accrued to a phase III, random-assignment trial comparing percutaneous hepatic perfusion (PHP-mel) (n=44) to standard of care (BAC) (n=49). This represents 100% of a planned 92 patient accrual. The primary endpoint was hepatic progression-free survival (H-PFS). Crossover to PHP-mel therapy was permitted at hepatic progression. Secondary endpoints included assessment of response rate (RR), duration of response (RES), and overall survival (OS) after PHP. A planned PHP treatment regimen included 4 to 6 PHP procedures at 28 to 35 day intervals. MEL (3.0 mg/kg) was delivered via the hepatic artery in a 30-minute hepatic artery infusion via a percutaneously placed catheter with hepatic venous hemofiltration using a retrohepatic, double balloon catheter (Delcath Systems, Inc.) and paired hemofiltration cartridges. Patients randomized to BAC were offered treatment considered to be the best alternative regimen by the treating physician. Staging evaluations were performed at baseline and then at 6 to 8 week intervals post baseline. All responses represent investigator-based results and were evaluated via standard RECIST criteria. Intent to treat based survival analysis was via the Kaplan-Meier method, with a 2-sided p< 0.05 defining significance. Results: Median H-PFS was 245 days (CI:136, 267) for PHP-mel vs. 49 days (CI:43, 68) for BAC (p<0.001). Overall response rate was 34.1 % (15/44) (CI: 20.5, 49.9) for PHP (15/44) vs. 2.0 % (1/49) (CI: 0.1, 10.9) for BAC (p<0.001). Upon hepatic progression, crossover to PHP occurred in 27 patients (55%) randomized to BAC. Conclusions: For patients with metastatic melanoma to the liver, H-PFS is significantly improved with PHP-mel versus best available care. [Table: see text]

LBA4002 Background: Surgical resection is a recommended treatment for operable gastric cancer (GC) in general, despite high recurrence rates (40%–80%). Adjuvant chemotherapy aims to reduce recurrences; however, there is currently no universally accepted adjuvant regimen for GC. Methods: CLASSIC is a randomized, open-label, multicenter, international (South Korea, China, and Taiwan) study of XELOX (capecitabine 1000mg/m2 bid, d1–14, q3w and oxaliplatin 130mg/m2, d1, q3w x 8 cycles) vs observation, following D2 gastrectomy. Eligible patients were chemotherapy- and radiotherapy-naive, with stage II (T2N1, T1N2, T3N0), IIIa (T3N1, T2N2, T4N0), or IIIb (T3N2) GC resected within 6 weeks prior to randomization. The primary endpoint is 3-year disease-free survival (DFS). A sample size of 512 patients per arm was planned to observe the 385 DFS events required to provide 80% power at a 5% significance level for the hypothesized treatment effect (hazard ratio [HR] 0.75). The Independent Data Monitoring Committee recommended full evaluation and reporting of results following a positive pre-planned interim analysis at 266 events. Results: The XELOX and observation arms (ITT populations of 520 and 515 patients, respectively) were well balanced for baseline characteristics. The median duration of follow-up was 34.4 (16–51) months. XELOX-related grade 3/4 adverse events (AEs) occurred in 244/496 patients (49%) of the safety population. Neutropenia was the only AE observed in >10% of patients (21%, n=106/496). Serious XELOX-related grade 3/4 AEs occurred in 34/496 patients (7%). There were 62/496 (13%) and 80/476 (17%) deaths on study in the safety populations of XELOX and observation arms, respectively, mostly due to disease progression. Efficacy results in the ITT population are summarized below. Conclusions: This study demonstrates the superior efficacy of adjuvant XELOX vs observation alone following D2 gastrectomy. Although OS data are still immature, there is a trend towards superiority of XELOX. These data support the use of adjuvant XELOX for GC. [Table: see text]
