The Evolving Approach to Management of Cancer CachexiaCancer patients are often referred for cachexia intervention treatments late in their disease trajectory-that is, at a point where attempts to reverse the weight loss process may be less beneficial. In addition, healthcare professionals frequently under-recognize the prevalence of cancer cachexia, and this may contribute to delayed treatment of weight loss, often until the refractory stage.

National Guidelines for Palliative Care: A Roadmap for Oncology NursesPatients with cancer have significant needs for palliative care, including pain and symptom management and psychosocial and spiritual support. The experience of cancer has an impact on family caregivers as well, and palliative care needs exist from diagnosis through survivorship and end-of-life care. Oncology nurses have opportunities to integrate palliative care into disease-focused care.

Commentary (Kwok/Patchell): Radiation Therapy in the Management of Brain Metastases From Renal Cell CarcinomaBrain metastases from renal cell carcinoma (RCC) cause significant morbidity and mortality. More effective treatment approaches are needed. Traditionally, whole-brain radiotherapy has been used for palliation. With advances in radiation oncology, stereotactic radiosurgery and hypofractionated stereotactic radiotherapy have been utilized for RCC brain metastases, producing excellent outcomes. This review details the role of radiotherapy in various subgroups of patients with RCC brain metastases as well as the associated toxicities and outcomes. Newer radiosensitizers (eg, motexafin gadolinium [Xcytrin]) and chemotherapeutic agents (eg, temozolomide [Temodar]) used in combination with radiotherapy will also be discussed.

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.

Adjuvant Treatment of Stage IB NSCLC: The Problem of Stage Subset HeterogeneityStage IB non–small-cell lung carcinoma (NSCLC) represents a subset of early-stage, resectable NSCLC, usually treated with curative intent, but with historically modest 5-year survival rates ranging from 40% to 67% with surgical resection alone.[1,2] Disappointingly, modern adjuvant chemotherapy trials including stage IB patients have shown little evidence of chemotherapeutic benefit.

The Best Treatment for Diffuse Large B-Cell Lymphoma: A German PerspectiveWhile some improvement was achieved by adding etoposide and shortening the treatment intervals from 3 to 2 weeks (CHOEP-14), best results in young good-prognosis patients (age-adjusted International Prognostic Index [IPI] = 0,1) have been achieved with six cycles of CHOP (cyclophosphamide, doxorubicin HCl, vincristine [Oncovin], prednisone)-like chemotherapy in combination with the anti-CD20 antibody rituximab (Rituxan). The role of additional radiotherapy in this setting remains to be determined. With this approach, 2-year eventfree survival rates of > 90% and overall survival of > 95% can be achieved in a very favorable subgroup (patients without IPI risk factor and no bulky disease), while further improvement is warranted for the less favorable subgroup (event-free survival only 77%). For young poorprognosis patients (age-adjusted IPI ≥ 2), the 5-year survival is around 50%, and progress has not been convincingly and specifically demonstrated in these patients. Ongoing studies will show whether dose-dense conventional or high-dose chemotherapy regimens requiring stem cell support in combination with rituximab will result in similar improvements of outcome as has been reported recently for young patients with good-prognosis aggressive lymphoma. In elderly patients, CHOP interval reduction from 3 to 2 weeks (CHOP-14) and the addition of rituximab to CHOP-21 achieved similar improvements in outcome. The ongoing RICOVER-60 (rituximab with CHOP over 60) trial of the German High-Grade Non-Hodgkin’s Lymphoma Study Group (DSHNHL) evaluates whether the combination of both approaches (R-CHOP-14) can further improve the prognosis of elderly patients.

Optimal Combination With PUVA: Rationale and Clinical Trial UpdateCutaneous T-cell lymphoma (CTCL) is relatively benign in its early stages, but survival rates decrease dramatically as the disease progresses. As no curative therapies are currently available, the goal of therapy is preventing or delaying progression from early disease stages while minimizing long-term toxicity. No single agent, including psoralen plus ultraviolet A (PUVA), can control disease progression fully, so combination therapy is needed to improve response rates. In addition, low-dose combination therapy may improve treatment safety and tolerability. A combination of PUVA and interferon (IFN)α in early disease has been shown to be effective and well tolerated. Likewise, small studies of PUVA and bexarotene (Targretin) indicate good efficacy for this combination. Reduced doses of these combinations may also be effective as maintenance therapies following complete remission. Other treatment combinations shown to be effective in early disease stages include bexarotene with IFNα, and bexarotene with denileukin diftitox (Ontak). In advanced stages of CTCL, liposomal-encapsulated doxorubicin or extracorporeal photopheresis may be combined with bexarotene or IFNα.
