Various chemotherapeutic agents as well as the anti-CD20 antibody rituximab (R) have been tested in patients with mucosa-associated lymphoid tissue (MALT) lymphoma, but no standard chemotherapeutic regimen has emerged so far. Judging from the data obtained in various types of lymphoma, the activity of R appears to be enhanced by combination with chemotherapy. As no data on this topic exist for MALT lymphoma, we have retrospectively analysed our experience with R plus cyclophosphamide, doxorubicin/mitoxantrone, vincristine and prednisone (R-CHOP/R-CNOP) in patients with relapsed MALT lymphoma. ⋯ Our data demonstrate a high activity of R-CHOP/R-CNOP in relapsing MALT lymphoma irrespective of prior therapy.

The characteristics and risk factors of the long-term ototoxic effect of cisplatin in testicular cancer patients was studied by measuring distortion product otoacoustic emissions (DPOAEs), which is a highly sensitive, new method for detecting high-frequency hearing loss. ⋯ DPOAE is a fast, noninvasive and reliable method in detecting late ototoxicity in testicular cancer patients. Contrary to the literature, not only high frequencies are affected. In patients receiving at least 400 mg/m2, using DPOAE we were able to detect significant hearing impairment at lower frequencies that are important for speech perception.

Cytokines are potential new serum markers, especially desirable for malignancies with poor prognosis like non-small cell lung cancer (NSCLC). ⋯ Increased pretreatment serum M-CSF level is a significant independent predictor of poor survival in patients with NSCLC.

Because of its proven efficacy profile based on long-term data, tamoxifen has been the standard adjuvant endocrine therapy for hormone-sensitive early breast cancer for the past 30 years. However, there is well-established evidence that long-term use of tamoxifen is associated with serious side effects. As adjuvant endocrine therapy is generally administered for long periods of time, the safety and tolerability of agents used in this setting are of particular importance. ⋯ The AIs have differing pharmacological profiles, which may translate into dissimilar adverse event profiles in the adjuvant treatment setting, but patient follow-up in most trials is relatively short to make a valid comparison. It cannot, therefore, be assumed that all AIs will be equally well tolerated in the adjuvant setting. Further data on the long-term safety of AIs other than anastrozole are therefore required to allow overall risk:benefit assessments on these agents to be made.
