Vesicant Extravasation From an Implanted Venous Access PortThe patient, “JB,” is a 68-year-old woman who underwent a right lumpectomy and axillary node dissection for stage II breast cancer. Her oncologist suggested adjuvant chemotherapy (four cycles of cyclophosphamide [Cytoxan] at 600 mg/m2 plus doxorubicin [Adriamycin] at 60 mg/m2) followed by local radiation therapy.

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

Are We Overtreating Some Patients With Rectal Cancer?The definition of overtreatment of rectal cancer is controversial,and thus it is difficult to accurately quantitate its prevalence. All componentsof rectal cancer treatment are associated with significant potentialfor morbidity and dysfunction that may have a negative impacton the patient’s quality of life. No one would disagree with the tenetthat overtreatment should be avoided whenever possible. Despite thatconsensus, little attention is given in the literature to the issues ofovertreatment of rectal cancer. This review article presents a varietyof clinical scenarios and summarizes available data demonstratingthat overtreatment of some patients with rectal cancer is occurring ona regular basis. It is hoped that this will stimulate clinicians to criticallyreview their own practices to eliminate such overtreatment. Developmentof new clinical trials to determine whether current practiceguidelines are promoting overtreatment of selected rectal cancer patientsis proposed.

High-Dose Chemotherapy With Autologous Stem Cell Rescue in the Outpatient SettingIntensive outpatient care is rapidly becoming the primary mode of care for selected patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell (PBSC) transplantation. Although the traditional inpatient model of care may still be necessary for high-risk patients, published data suggest that outpatient care is safe and feasible during or after administration of high-dose chemotherapy and autologous PBSC transplant. Blood and marrow transplant (BMT) centers have developed programs to provide more outpatient care under three basic models: an early discharge model, a delayed admission model, and a comprehensive, or total, outpatient model. This review will describe these models of care and address the elements necessary for the development of an outpatient BMT program, including patient selection, staff development, and patient and caregiver education. Available supportive care strategies to facilitate outpatient care will also be highlighted.

Commentary (Livingston): Coming to Grips With Hand-Foot SyndromeScheithauer and Blum have madean important contribution to thediscussion of hand-foot syndrome,an increasingly common disorder.They emphasize the occurrenceof hand-foot syndrome in the contextof therapy with capecitabine (Xeloda),a prodrug for fluorouracil (5-FU)that in many ways mimics the continuousinfusion of that compound. Theauthors point out that the only provenmethod for managing hand-foot syndromeis interruption and/or reductionin the dose of the administeredtreatment, and they cite retrospectivedata from completed trials in colorectalcancer to support the hypothesisthat such a policy does not impair treatmentefficacy. We feel that severalpoints deserve further amplification.

Pituitary Adenomas: Current Methods of Diagnosis and TreatmentPituitary adenomas are benign neoplasms that can be effectively managed by a variety of therapeutic options. The clinician's goal in managing patients with these tumors should be to minimize the morbidity of each intervention used in diagnosis and treatment. Standard diagnostic interventions include MRI, hormonal assessment, and tissue diagnosis. Therapies include transsphenoidal surgery, external-beam radiotherapy, newer stereotactic irradiation techniques, and medical management. Appropriate treatment selection requires detailed knowledge of the expected outcomes and side effects of each option. Newer and perhaps less toxic treatment techniques are evolving and require further evaluation. [ONCOLOGY 11(6):791-796, 1997]

Radiofrequency Ablation in Lung Cancer: Promising Results in Safety and EfficacyOnly about 15% of patients diagnosed with lung carcinoma eachyear are surgical candidates, either due to advanced disease orcomorbidities. The past decade has seen the emergence of minimallyinvasive therapies using thermal energy sources: radiofrequency,cryoablation, focused ultrasound, laser, and microwave; radiofrequencyablation (RFA) is the best developed of these. Radiofrequency ablationis safe and technically highly successful in terms of initial ablation.Long-term local control or complete necrosis rates drop considerablywhen tumors are larger than 3 cm, although repeat ablations can beperformed. Patients with lung metastases tend to fare better with RFlung ablation than those with primary lung carcinoma in terms of localcontrol, but it is unclear if this is related to smaller tumor size at time oftreatment, lesion size uniformity, and sphericity with lung metastases,or to differences in patterns of pathologic spread of disease. The effectsof RFA on quality of life, particularly dyspnea and pain, as well aslong-term outcome studies are generally lacking. Even so, the resultsregarding RF lung ablation are comparable to other therapies currentlyavailable, particularly for the conventionally unresectable or high-risklung cancer population. With refinements in technology, patient selection,clinical applications, and methods of follow-up, RFA will continueto flourish as a potentially viable stand-alone or complementarytherapy for both primary and secondary lung malignancies in standardand high-risk populations.
