Metronomic oral vinorelbine as first-line treatment in elderly patients with advanced non-small cell lung cancer: results of a phase II trial (MOVE trial).

BACKGROUND: Metronomic oral vinorelbine could be a safe option for elderly patients with advanced non small cell lung cancer (NSCLC). Metronomic administration of chemotherapy leads to a cytostatic action shifting treatment target from cancer cell to tumor angiogenesis. METHODS: 43 chemotherapy naive elderly (≥ 70 yrs) PS 0-2 patients with stage IIIB-IV NSCLC were prospectively recruited. Median age was 80 yrs (M/F 36/7) with predominantly squamous histology. PS distribution was 0-1(16)/2(27) with a median of 3 serious co-morbid illnesses. Study treatment consisted of oral vinorelbine 50mg three times weekly (Monday-Wednesday-Friday) continuously until disease progression, unacceptable toxicity or patient refusal. Primary endpoints were overall response rate (ORR), clinical benefit (CB--disease response plus disease stabilization >12 weeks) and safety. Health-related QoL (HRQoL) was also assessed with FACT-L V4 scoring questionnaire. We conducted an exploratory time-course analysis of VEGF and thrombospondin-1 (TSP1) serum levels in a subgroup of patients. RESULTS: Patients received a median of 5 (range 1-21) cycles with a total of 272 cycles delivered. ORR was 18.6% with 7 partial and 1 complete responses; 17/43 experienced stable disease lasting more than 12 weeks leading to an overall CB of 58.1%. Median time to progression was 5 (range 2-21) and median overall survival 9 (range 3-29) months. Treatment was well tolerated with rare serious toxicity. Regardless of severity main toxicities observed were anemia in 44%, fatigue in 32.4%, and diarrhoea 10.5%. FACT-L v4 scores did not significantly vary during treatment. Baseline VEGF levels were lower and showed a rapid increase during treatment in non-responders pts only while TSP1 levels did not change. CONCLUSIONS: Metronomic oral vinorelbine is safe in elderly patients with advanced NSCLC with an interesting activity mainly consisting in long-term disease stabilization coupled with an optimal patient compliance (Eudra-CT 2010-018762-23, AIFA OSS on 26 February 2010).

Fulvestrant treatment is associated with cholesterol plasma level reduction in hormone-receptor-positive metastatic breast cancer patients.

BACKGROUND: Fulvestrant is a pure anti-estrogen hormoal agent formally lacking any estrogen-agonist activity. We analyze the effect(s) of fulvestrant treatment on estrogen target systems in hormoe-sensitive advanced breast cancer patients. RESULTS: Patients received a median of five fulvestrant injections (range 3-19). We observed a partial response in one patient, disease stability in 21 and disease progression in 29 patients with a clinical benefit of 43.2% and a median time to progression of 5 [range 3-20] mo. Total cholesterol levels significantly decreased during treatment (219.8 +/- 45.3 vs. 201.4 +/- 42.1 mg/dl; p = 0.0054) together with LDL-cholesterol (129.7 +/- 41.39 vs. 112.3 +/- 37.1 mg/dl; p = 0.018). HDL-cholesterol and triglycerides did not show significant changes. Reduction of total and LDL-cholesterol was independent from last hormoal treatment or treatment duration. All coagulation indices and mean endometrial mucosa thickness value did not vary. METHODS: Fifty-one patients [median age 65 (range 48-82) y] were enrolled. All patients received previous hormoal treatments, with 90.2% receiving > or =2 courses. Last hormoal treatment was exemestane, letrozole, anastrozole and other in 30-10-7-4/51 patients respectively. Median withdrawal time was 18 d (range 3-1456). Complete fasting lipid blood profile and coagulation indices were assessed before fulvestrant administration, every 3 mo and at discontinuation time. Endometrial mucosa thickness was evaluated before fulvestrant administration and at end-study time. CONCLUSIONS: We observed a lipid lowering effect of fulvestrant possibly related to an influence on lipid metabolism by a mechanism in which a role could be played by progesterone receptor.

Sorafenib in a patient with advanced hepatocellular carcinoma and serious impairment of left ventricular function: a case report.

INTRODUCTION: sorafenib, a tyrosine-kinase inhibitor, is widely used in the treatment of advanced hepatocellular carcinoma. Drug-related toxicities are generally mild but sorafenib, as other similar agents, may induce elevation of systemic arterial blood pressure levels in relation to an interaction with cardiovascular system probably mediated by HIF pathway. This side effect may be particularly critical for patients with underlying serious heart disease as it can induce acute heart failure, a life-threatening condition, and usually such patients are excluded from active treatment with tyrosine-kinase inhibitors. We report the case of a patient affected by advanced hepatocellular carcinoma and serious impairment of cardiac function treated with sorafenib without any worsening of heart function. To our knowledge this is the first report of this kind in the literature. CASE PRESENTATION: We report the case of a 74-year-old patient affected by advanced multifocal HCV-cirrhosis related hepatocellular carcinoma and severe post-ischemic fall of left-ventricular function with serious risk of cardiac functional impairment. The patient presented with an ECOG performance status of 0. Blood chemistry tests showed a substantial elevation of alpha-fetoprotein values and slight increases of bilirubin, of gamma-GT and of GOT; the absence of encephalopathy and ascites and the normality of coagulation parameters and of albumin led to classify the patient into the functional class Child-Pugh A. The patients was successfully treated with sorafenib at the reduced daily dose of 400 mg for long-time without any worsening of heart function. CONCLUSION: The presented case can offer to oncologists a clinical support to take into consideration when deciding to treat with sorafenib advanced hepatocellular carcinoma patients presenting with serious impairment of cardiac function that are usually excluded from an active treatment.

Ipsilateral right testicular metastasis from renal cell carcinoma in a responder patient to interleukine-2 treatment.

We present a case of metastatic spreading to the testicle in a 46-year-old patient with renal cell carcinoma, "clear-cell" type, during interleukin-2 combined subcutaneous plus aerosol treatment. Testicular metastasis occurred while the patient showed a response to the treatment with disappearance of lung lesions and reduction of lymph-nodes lesions. After orchiectomy with spermatic cord resection and disease re-evaluation confirming the previous response, the patient re-started immunotherapy. The contrast between systemic disease response to treatment and disease testicular progression might be explained by a relative insensitivity of the testicle to interleukin-2 immunotherapy as a result of a possible establishment of an immunosuppressive microenvironment. We believe that the rarity of this metastatic site and the intriguing possible mechanisms at its base, makes an interesting case for clinicians.
