Clinical TrialA dose escalation study of docetaxel and oxaliplatin combination in patients with metastatic breast and non-small cell lung cancer.
To determine the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of docetaxel in combination with oxaliplatin (L-OHP) as first-line treatment of patients with advanced breast (ABC) and non-small cell lung cancer (NSCLC). ⋯ The combination of docetaxel and oxaliplatin is a feasible and well-tolerated regimen. The recommended doses for future phase II studies are 75 mg/m2 for docetaxel on day 1 and 70 mg/m2 for L-OHP on day 2 without rhG-CSF support and 85 mg/m2 and 130 mg/m2, respectively, with rhG-CSF support.

Standardized mistletoe extract augments immune response and down-regulates local and metastatic tumor growth in murine models.
The immunomodulatory and antimetastatic activity of standardized aqueous mistletoe extract (sME) was evaluated in BALB/c-mice. Regular subcutaneous (s.c.) applications (three times per week for 14 consecutive days; 2, 20, 100 and 500 micrograms per injection and mouse) up-regulated thymocyte and peripheral blood leukocyte counts in tumor-bearing mice. ⋯ To check the influence of sME treatment on growth of experimental metastases, RAW 117 H 10 lymphosarcoma cells and L-1 sarcoma cells were intravenously inoculated into BALB/c-mice to establish liver and lung colonization, respectively. sME was regularly administered starting 24 hours after tumor cell challenge. Organ colonization was investigated on day 14 after tumor cell inoculation and demonstrated statistically significant (p < 0.05) reductions of experimental liver and lung metastases for sME-treated mice.

Clinical TrialEfficacy of combined radiation, paclitaxel and carboplatin for locally advanced non-small cell lung carcinoma.
Locally advanced non-small cell lung carcinoma (NSCLC) has a poor prognosis when treated with conventional chemotherapy and radiation. New chemotherapy agents like paclitaxel may increase the sensitivity of tumors cells to radiation and potentially improve the outcome. The optimal combination of taxane-based chemotherapy agents and radiation is still unclear. ⋯ The decrease of tumor volume following induction chemotherapy allows sparing of the lungs from the toxicity of radiation. However, grades 3-4 esophagitis remain significant. The addition of amifostine may be beneficial in this setting.

Prognostic significance of p53, bcl-2 and Ki-67 in high risk superficial bladder cancer.
Although tumor grade and stage are the most accurate prognostic factors in the evaluation of transitional cell bladder cancer, they cannot always predict the true tumor biological potential since superficial tumors of the same stage and grade may have completely different clinical courses. This study was performed in order to examine whether p53, bcl-2 and Ki-67 have any validity in predicting the course of superficial bladder tumors, with high risk for recurrence or progression, over the traditional prognostic factors that are currently used. Furthermore, we investigated whether any one of these markers maintains its prognostic capability after one course of intravesical instillations of IFN gamma. ⋯ The Ki-67 proliferative index has an independent validity in predicting those patients with high risk superficial bladder tumors who may recur in a short follow-up period. A similar relationship of Ki-67 overexpression to progression was not detected. The expression of p53 and bcl-2 does not seem to offer any prognostic information in predicting either recurrence or progression over the prognostic factors that are currently used in clinical practice.

Evaluation of infectious complications and immune recovery following high-dose chemotherapy (HDC) and autologous peripheral blood progenitor cell transplantation (PBPC-T) in 148 breast cancer patients.
High-dose chemotherapy (HDC) with autologous PBPC-T has been reported to be effective in hematological and in selected solid malignancies. In this setting, infectious complications represent a relevant cause of morbidity. ⋯ Altogether these results show that severe mucositis is associated with early bacterial infections and the infusion of large numbers of T-cells plays a role in controlling late VZV reactivation.
