We employed human lymphoblastoid interferon (HLBI) in the treatment of 4 cases of renal carcinoma with pulmonary metastases. All of the cases were males aged 58 to 62. On initial examination, it was revealed that all 4 cases already had multiple metastatic lesions in the lung as well as in other organs such as brain and bone. HLBI was injected i.m. daily at a dosage of 6 X 10(6) units. Treatment was continued for 33 to 119 days, with the total dose being 198 X 10(6) units to 714 X 10(6) units. As to tumor response, minor response was obtained in 1 case, no change in 2 cases, and progressive disease in 1 case. In the case in which minor response was obtained, the size of the pulmonary metastases had reduced by 30% after 8 weeks of treatment with HLBI. As side effects, we observed fever in all cases, and also, anorexia, general malaise, asthenia, and myelosuppression. However, none of these symptoms were serious enough to require discontinuation of HLBI medication. From the results obtained in our own cases, we believe that HLBI may become a new antitumor agent effective for renal cell carcinoma.

A 78-year-old man admitted to our hospital with signs and symptoms of right ventricular failure, consisting of severe edema of the scrotum and the penis, ankle edema, hepatomegaly, and a history of asthenia associated with a recent weight loss. Two-dimensional echocardiography showed an intracavitary mass in the right atrium and a moderate pericardial effusion; the remaining structures were normal. To better define the origin of this mass, transesophageal echocardiography was performed. The mass extended from the inferior vena cava with no sites of attachment to the atrial wall. The mass was elongated, mobile, with a triangular termination near the tricuspid valve, without signs of right ventricular obstruction. An abdominal-pelvic CT scan demonstrated the origin of the mass at the superior pole of the left kidney extending through the renal vein and the inferior vena cava into the right atrium. The mass was surgically removed and the pathological examination revealed a renal cell carcinoma (hypernephroma) of the clear cells subtype. After surgery, the patient did well with the resolution of the picture of right ventricular failure.

Thirty-five patients (pts.) with advanced renal cell carcinoma were treated with a combination of vinblastine (5 mg/m2/IV) plus epirubicin (50 mg/m2/IV) every 3-4 weeks, alpha-2-A-interferon (9 x 10(6) U/IM 3 times in the 1st week, then 18 x 10(6) U/IM 3 times weekly), and medroxyprogesterone acetate (2,000 mg/os/day plus 500 mg IM/week). Thirty-one patients were males and 4 were females with a median age of 63 years (range 35-75) and median performance status of 70% (range 50-90%). We observed nine partial remissions (26%) with median duration of 40 weeks (range 20-232+). Fifteen pts. had no change (43%) while 11 pts. progressed (31%). The main side-effects were: leukopenia (29/35, 83%) with median nadir of 3,100 WBC/mm3 (range 510-3,990) and fever (32/35, 91%). Thrombocytopenia occurred in 4 pts. (11%), anemia in 5 (14%), asthenia in 12 (34%), nausea/vomiting in 12 (34%), alopecia in 8 (23%) and stomatitis in 3 (8.5%). Two patients stopped the therapy with medroxyprogesterone acetate because of muscular cramps. Median survival was 65 weeks (range 6-327+). We conclude that the combination of recombinant alpha 2A-interferon-vinblastine-epirubicin and medroxyprogesterone acetate has modest but definitive activity in patients with advanced renal cell carcinoma.

Interleukin-2 (IL-2) therapy is associated with serious toxic effects on the cardiopulmonary system. Less frequent toxicity is described in liver and the gastrointestinal system. A case of severe liver toxicity is described in a patient who underwent long-term immunotherapy with IL-2 (4.5 MU/m(2) s.c. daily, 5 days per week for 6 weeks, with 4 weeks of interval) plus interferon-alpha (IFN-alpha) (3 MU s.c. t.i.w., also covering the intervals between IL-2 cycles) for a metastatic renal carcinoma. A review of the literature is provided. The patient tolerated well the immunotherapy scheduled with apparently only a World Health Organization (WHO) G3 anemia and a G2 asthenia and is still alive, with a disease-free survival of 28 months. Notwithstanding a complete absence of liver function test abnormality during all scheduled clinical controls, the patient developed portal hypertension due to liver cirrhosis, which was histologically demonstrated. All common etiologic viral and toxic agents were ruled out. Long-term IL-2 therapy can induce liver cirrhosis. The appearance of liver and spleen enlargement during IL-2 therapy can be considered an indicator of liver damage. Thus, in this setting, closer monitoring is warranted despite normal liver function tests.

We have performed a translational phase II trial testing an original immunotherapy schedule based on the monthly subcutaneous (s.c.) administration of hrGM-CSF (days 1 through 5) and very low dose hrIL-2 (days 6 through 15) in 19 patients with metastatic renal cell carcinoma. Bone pain, first dose reaction to GM-CSF, asthenia and fever were the most common side effects. A partial response, and a disease stabilization were respectively observed in 4 and 11 cases, with a rate of objective response and a disease control rate respectively of 21% and 79%. We recorded a time to progression of 9 months and a 2- and 3-year survival respectively of 42% (8/19 patients) and 26% (5/19 patients). Our results suggest that this GM-CSF/hrIL-2 combination is active and well tolerated in patients with renal cell carcinoma and deserves to be investigated in larger comparative trials.

Until 2006, immunotherapy (interferon-alpha or interleukin 2) was the standard medical treatment for metastatic renal cell carcinoma (RCC), and its results were disappointing: despite a few cases of complete response with prolonged survival, median survival was one year. Better understanding of the molecular mechanisms of tumor angiogenesis, especially in clear cell carcinoma, has led to the development of multiple targeted therapies to inhibit key effectors: vascular endothelial growth factor (VEGF), VEGF receptor, and mTOR (target of rapamycin). Two inhibitors targeting several protein kinases, including the VEGF receptor, have increased progression-free survival in patients with metastatic RCC and are now commercially available: sunitinib (Sutent) as first-line treatment and sorafenib (Nexavar) as second-line treatment. These targeted therapies will certainly affect overall survival, but it is too early for any firm conclusions. Their side-effects, usually low or moderate, include asthenia, anorexia, diarrhea, hand-and-foot syndrome and hypertension. Optimal management is required to ensure prolonged exposure. Other drugs have been effective: bevacizumab (Avastin), a monoclonal antibody inhibiting VEGF, increases progression-free survival as second-line treatment, and temsirolimus (Torisel), an mTOR protein kinase inhibitor, increases overall survival in the population of patients with poor prognosis. These targeted drugs will serve as the basis for development of future therapeutic strategies.

Sunitinib malate is a novel oral multitargeted tyrosine kinase inhibitor with antitumor and antiangiogenic activities. Sunitinib was recently approved in first-line treatment for patients with advanced renal cell carcinoma (RCC) and for the treatment of patients with gastrointestinal stromal tumors (GIST) after disease progression or intolerance to imatinib mesylate therapy. We report the very interesting results of the phase II trials after cytokin failure and of the randomized recent trial of sunitinib versus cytokin-based therapy in first-line treatment for patients with metastatic RCC, as well as the promising results of the recent trials on patients with GIST after disease progression or intolerance to imatinib mesylate therapy. Oral sunitinib demonstrates a high level of efficacy with acceptable tolerability with the 50 mg daily for 4 weeks followed by 2 weeks off schedule; a continuous schedule could be of interest. Hypertension and asthenia are the most common side effects with sunitinib. Regardless of these encouraging results, studies investigating sunitinib in first-line treatment (for patients with GIST), adjuvant and neoadjuvant settings are awaited, as well as trials using sunitinb in combination with chemotherapy or other targeted therapies. Clinical trials investigating sunitinib in other tumor types are ongoing.

The targeted therapies sunitinib, sorafenib, temsirolimus, and bevacizumab (when used in combination with interferon-alpha2a) have dramatically improved outcomes for patients with advanced renal cell carcinoma (RCC). Clinical application of these novel agents outside the trial setting, however, may present some challenges for treating individual patients with unique needs. In some patients, dose modifications may be considered for potential drug interactions and for management of severe cases of hematologic or nonhematologic toxicities. The more common grade 3 or 4 side effects with sunitinib and sorafenib include hypertension, fatigue, hand-foot syndrome, elevated lipase, lymphopenia, and neutropenia. Congestive heart failure is a less common but serious side effect that warrants treatment discontinuation. Temsirolimus exhibits a different side-effect profile, with the more common grade 3 or 4 side effects being metabolic in nature (i.e., elevated triglycerides, elevated glucose, hypophosphatemia) as a result of its inhibitory effects on the mammalian target of rapamycin-regulated lipid and glucose pathways. Asthenia, rash, and dyspnea also occur in patients receiving temsirolimus. Virtually all of the side effects associated with these agents can be managed effectively in the majority of patients with medical treatment or supportive interventions. Recognition and prompt management of side effects are important to avoid unnecessary dose reductions that may result in suboptimal efficacy.

Sunitinib is a novel, oral, multi-targeted tyrosine kinase inhibitor with antiproliferative effects against cancer cells and antiangiogenic properties. Sunitinib was recently approved for the first-line treatment of patients with advanced renal cell carcinoma (RCC) and for the treatment of patients with gastrointestinal stromal tumours (GIST) after disease progression or intolerance to imatinib therapy. The main purpose of this benefit-risk assessment is to review data on sunitinib efficacy along with its toxicity in patients with GIST and RCC. Sunitinib demonstrates a high level of efficacy with acceptable tolerability using either the 50 mg daily oral dosing for 4 weeks every 6 weeks or a continuous daily administration schedule at a lower dose. Hypertension and asthenia appear to be the most common adverse effects with sunitinib. Diarrhoea, anorexia, disgeusia, stomatitis and skin toxicity are other clinically relevant toxicities. Fatigue may, at least in part, be related to the development of hypothyroidism during sunitinib therapy. Skin toxicity consists of bullous lesion in the soles and palms that may require treatment discontinuation for a few days and/or dose reduction. Thyroid hormone levels should be monitored during treatment with sunitinib, with the occurrence of clinical signs of hypothyroidism needing treatment with levothyroxine sodium. Hypertension usually requires standard antihypertensive therapy and treatment discontinuation is less frequently necessary. Mild neutropenia and thrombocytopenia usually require no intervention. A decrease in left ventricular ejection fraction is a rare but potentially life-threatening complication. Although usually well tolerated, sunitinib needs to be administered cautiously with medical follow-up in patients with cancer to prevent, avoid and treat adverse effects in order to improve patient compliance. Its established antitumor activity requires attempting to maintain the highest tolerable dose in individual patients. Current oral formulations allow physicians to modulate dosages (between 25 and 50 mg/day) and/or schedules (4 weeks on, 2 weeks off or continuous administration) to optimize the benefit-risk profile of sunitinib in individual patients.

PURPOSE Effects of specific antineoplastic therapies on progression of cancer-associated wasting remain uncharacterized. We selected a targeted therapy, sorafenib, because of its reported association with weight loss. PATIENTS AND METHODS Patients with metastatic renal cell cancer (RCC) who were resistant to standard therapy (N = 80) received sorafenib 400 mg twice daily or placebo in a randomized, double-blinded clinical trial. Computed tomography image analysis, which has high precision and specificity for evaluation of specific muscles and adipose tissues, was used to define change in total skeletal muscle and adipose tissue. Results At inclusion, 51% of patients were overweight or obese (ie, body mass index [BMI] > 25 kg/m(2)). Only 5% were underweight. Advanced muscle wasting (ie, sarcopenia) was present in 72% of patients with BMI less than 25 and in 34% of those with a BMI greater than 25. Patients received placebo for an average of 6 months and received sorafenib for 1 year. Patients in the placebo group had stable body weight during 6 months (0.8 kg +/- 0.7 kg), with no significant alteration of muscle or fat. Patients who received sorafenib lost 2.1 kg +/- 0.6 kg (P < .01) in 6 months and lost 4.2 kg +/- 0.7 kg (P < .01) by 1 year. Sorafenib-treated patients lost skeletal muscle progressively at 6 months (decrease of 4.9%; P < .01) and 12 months (decrease of 8.0%; P < .01). CONCLUSION Sarcopenia is prevalent in patients with metastatic RCC and is an occult condition in patients with normal or high BMI. Muscle loss is specifically exacerbated by sorafenib, consistent with the evidence for a role of kinases in regulating muscle mass. Muscle loss is a sorafenib adverse effect that may relate to asthenia, fatigue, and physical disability.
