Anthracycline and Trastuzumab in Breast Cancer Treatment

This study was designed to evaluate the cardiac safety of the combined treatment of HER2-positive metastaticbreast cancer patients with trastuzumab (Herceptin) plus epirubicin and cyclophosphamide (EC) incomparison with EC alone in HER2-negative metastatic breast cancer patients. Patients included those withmetastatic breast cancer without any prior anti-HER2 treatment, anthracycline therapy, or any other chemotherapyfor metastatic disease. This was a nonrandomized, prospective, dose-escalating, multicenter, openlabel,phase II study in Germany. A control group of 23 patients received EC 90/600 mg/m2 3-weekly for sixcycles (EC90 alone). A total of 26 HER2-positive patients were treated with trastuzumab, or H (2 mg/kg weeklyafter an initial loading dose of 4 mg/kg), and EC 60/600 mg/m2 3-weekly for six cycles (EC60+H); another 25HER2-positive patients received H and EC 90/600 mg/m2 3-weekly for six cycles. Asymptomatic reductions inleft ventricular ejection fraction (LVEF) of more than 10% points were detected in 12 patients (48%) treatedwith EC60 + H and in 14 patients (56%) treated with EC90 + H vs 6 patients (26%) in the EC90 alone cohort.LVEF decreases to < 50% occurred in one patient in the EC60+H cohort and in two patients in the EC90+Hcohort during the H monotherapy. No cardiac event occurred in the cohort with EC90 alone. The overallresponse rates for EC60+H and EC90+H were >60%, vs 26% for EC90 alone. The interim results of this studysuggest the cardiac safety of the combination of H with EC may be greater than that of H with AC (doxorubicin[Adriamycin]/cyclophosphamide); however, studies in larger numbers of patients are warranted. The combinationregimen revealed promising efficacy.

Rituximab Plus CHOP in the Treatment of Elderly Patients With Diffuse Large B-Cell Lymphoma: An Update of the GELA Study

At the 2000 Annual Meeting of the American Society of Hematology, we presented the benefits of rituximab (Rituxan) combined with CHOP (cyclophosphamide [Cytoxan, Neosar], doxorubicin HCl, vincristine [Oncovin], prednisone), known as R-CHOP, in comparison with CHOP alone for the treatment of elderly patients with diffuse large B-cell lymphoma (DLCL).

Management of Difficult Germ-Cell Tumors

Although testicular cancer is a rare disease accounting for only 1% of all male neoplasms, it represents a paradigm for cancer curability. Overall, more than 95% of patients can expect to be cured of their disease with minimal long-term toxicity. Given these expectations, it is critical that cancer care providers are familiar with the diagnostic and therapeutic challenges encountered in these rare patients. In particular, clinicians managing these patients should be aware of some of the pitfalls encountered when determining relapse. In a series of case presentations, we review the evaluation and management of patients with persistent elevation of serum tumor markers and postchemotherapy residual radiographic abnormalities.

Hematopoietic Stem Cell Transplantation in the Elderly

Hematopoietic stem cell (HSC) transplantation may improve outcomes of patients with hematologic malignancies not curable with conventional therapies. In some clinical settings, transplantation represents the only curative option. The feasibility and efficacy of this approach in older patients are undefined, since this population has been excluded from nearly all clinical trials. Advances in supportive care, HSC harvesting, and safer conditioning regimens have made this therapy available to patients well into their 6th and 7th decades of life. Recent evidence suggests that elderly patients with good performance status and no comorbidities could, in fact, not only survive the transplant with reasonable risk, but also benefit in the same measure as younger patients.

Current Challenges of Gene Therapy for Prostate Cancer

Gene therapy for prostate cancer faces hurdles similar to those being encountered for other cancers and nonmalignant processes. The greatest obstacle is the identification of efficient delivery systems, since numerous animal models and cell culture systems have shown potential efficacy when most cells express the introduced genetic material. Early prostate cancers are easily accessible to gene vector introduction, and the predictable metastatic patterns of this cancer may offer additional advantages for gene therapy. This article reviews gene vectors and gene products, as well as ongoing trials of gene therapy that have recently begun in prostate cancer. [ONCOLOGY 11(6):845-856, 1997]

Irinotecan/Cisplatin Followed by 5-FU/ Paclitaxel/Radiotherapy and Surgery in Esophageal Cancer

Local-regional carcinoma of the esophagus is often diagnosed inadvanced stages because the diagnosis is established when symptomsare severe. The prognosis of patients with local-regional carcinoma ofthe esophagus continues to be grim. While preoperative chemoradiotherapyincreases the fraction of patients who achieve pathologiccomplete response, that percentage is approximately 25%. In an attemptto increase the number of patients with either no cancer in the surgicalspecimen or only microscopic cancer, we adopted a three-step strategy.The current study utilized up to two 6-week cycles of induction chemotherapywith irinotecan (CPT-11, Camptosar) and cisplatin as step 1.This was followed by concurrent radiotherapy and chemotherapy withcontinuous infusion fluorouracil (5-FU) and paclitaxel as step 2. Oncethe patients recovered from chemoradiotherapy, a preoperative evaluationwas performed and surgery was attempted. All patients signed aninformed consent prior to their participation on the study. A total of 43patients were enrolled. The baseline endoscopic ultrasonography revealedthat 36 patients had a T3 tumor, five patients had a T2 tumor, andtwo had a T1 tumor. Twenty-seven patients had node-positive cancer(N1). Thirty-nine (91%) of the 43 patients underwent surgery; all hadan R0 (curative) resection. A pathologic complete response was noted in12 of the 39 patients. In addition, 17 patients had only microscopic(< 10%) viable cancer in the specimen. Therefore, a significant pathologicresponse was seen in 29 (74%) of 39 taken to surgery or 29 (67%)of all 43 patients enrolled on the study. With a median follow up beyond25 months, 20 patients remain alive and 12 patients remain free ofcancer. Our preliminary data suggest that the proportion of patientswith significant pathologic response can be increased by using thethree-step strategy.

Commentary (Baraboutis/Noskin): Management of Health-Care–Associated Infections in the Oncology Patient

Drs. Guinan, McGuckin, andNowell have nicely reviewedthe risk factors associatedwith increased susceptibility to hospital-acquired infection in oncologypatients and also discussed preventivesteps to attenuate those risks.We agree that patients with malignanciespresent a challenge to thehealth-care provider, as infection willdevelop at some point in almost allcancer patients[1] and may be associatedwith significant mortality.[2]

Superficial Bladder Cancer: Decreasing the Risk of Recurrence

Dr. Grossman's article provides a well-organized review of the literature on the treatment of superficial bladder cancer. At the time of diagnosis, approximately 80% of patients with bladder cancer have superficial tumors (limited to the urothelial lining of the bladder or the underlying lamina propria). In such patients, the risk of distant disease is low, and the natural history of bladder cancer is based on two separate, but related processes: tumor recurrence and progression to a higher stage of disease.

Neoadjuvant Androgen Deprivation Before Prostatectomy in T1-T3 Patients

Androgen deprivation has been used prior to radical prostatectomy in an attempt to improve local control of prostate cancer and delay time to cancer progression. Thirty men (mean age of 65) with clinical stage T3 adenocarcinoma of the prostate were entered into a phase II trial at the University of California, San Francisco, examining the effects of neoadjuvant androgen deprivation (luteinizing hormone-releasing agonist and an antiandrogen) before radical prostatectomy. Twenty-six of these patients subsequently underwent radical prostatectomy. Despite impressive physiological changes in prostate and tumor volume, stage reduction was noted in only 4 patients (15%). Overall, with a mean follow-up of 32.7 months, 72% of patients had evidence of disease recurrence, including detectable PSA. Several series suggest that in patients with stage T1 and T2 disease, the likelihood of a positive surgical margin after radical prostatectomy is decreased substantially by neoadjuvant deprivation. The effect on long-term disease-free survival, however, is still unknown. [Oncol News Int 6(Suppl 3):16-17, 1997

The Road to Romiplostim Approval and Beyond

Management of Early-Stage Lung Cancer: Past, Present, and Future Adjuvant Trials

The standard of care with regard to adjuvant chemotherapy of lung cancer has changed remarkably over the past 3 years. Until the initial report of the International Adjuvant Lung Trial in 2003, there was no real evidence from any individual randomized clinical trial (RCT) that adjuvant chemotherapy improves survival in resectable non-small-cell lung cancer. However, five RCTs that have now been reported indicate that adjuvant chemotherapy is effective, at least in certain subgroups of resectable patients. Moreover, numerous meta-analyses have also reported a positive effect from adjuvant treatment. Nonetheless, because of methodologic issues and conflicting results, the question of who should be treated and what constitutes optimal adjuvant therapy remains controversial. This article reviews the recent randomized trials that have contributed to a change in the state of the art, as well as some of the methodologic problems that may have confounded their proper interpretation. It also considers newer approaches to adjuvant therapy, with a particular focus on strategies that incorporate our growing knowledge of molecular medicine and predictive factors to the field of adjuvant chemotherapy of lung cancer.

Adjuvant vs Neoadjuvant Chemotherapy in Resectable NSCLC: Is That the Real Question?

Besse and Le Chevalier provide us with an excellent and comprehensive review of available literature summarizing the current state of the art relating to both adjuvant and neoadjuvant (or induction) chemotherapy in resectable non–small-cell lung cancer (NSCLC).[1] They review the efficacy of adjuvant and neoadjuvant treatment in randomized clinical trials (RCTs) that employ cisplatin-based chemotherapy in stages I, II, and IIIA NSCLC, as well as meta-analyses of these RCTs.

Management of Patients With Muscle-Invasive and Metastatic Bladder Cancer

Bladder cancer is the fifth most common cancer diagnosed in theUnited States. Prognosis for this disease is dependent on both tumorstage and grade. Radical cystectomy has been the standard treatmentfor muscle-invasive local disease; however, combined-modality approacheswith the use of chemotherapy are gaining momentum withdata suggesting survival improvement. Patients with metastatic diseasehave poor long-term survival rates despite systemic multiagent chemotherapy.A variety of agents, including newer cytotoxic drugs and biologicallytargeted agents, are under investigation to determine the mosteffective regimen. The special needs of specific patient populations,such as the elderly, those with a suboptimal performance status, andpatients with medical comorbidities have gained more attention.Progress in the treatment of this disease is dependent on supportingongoing and future clinical trials.
