A phase II study of sequential docetaxel and gemcitabine followed by docetaxel and carboplatin as first-line therapy for non-small cell lung cancer

Phase II study of gemcitabine plus docetaxel as second-line treatment in malignant pleural mesothelioma: a single institution study

OBJECTIVE

The combinations of cisplatin-pemetrexed and cisplatin-gemcitabine are considered the standard systemic therapy for malignant pleural mesothelioma (MPM), which is a rapidly progressive tumor. The purpose of the present study is to evaluate the efficacy, safety, and clinical benefit of the gemcitabine plus docetaxel regimen in the second-line treatment of this disease.

PATIENTS AND METHODS

A total of 37 patients with MPM were treated with the combination of docetaxel (80 mg/m) and gemcitabine (1000 mg/m) on day 1 and 14 of a 28-day cycle. The regimen was repeated for a maximum of 6 cycles or until disease progression or unacceptable toxicity.

RESULTS

There was partial response of the disease in 7 patients (18.9%), whereas it remained stable in 23 patients (62.2%) and progressed in 7 patients (18.9%). The median time to disease progression was 7 months (range: 5.8-8.2 months) with a mean survival of 16.2 months (range: 13-19.3 months).

CONCLUSION

The biweekly administration of docetaxel and gemcitabine, along with granulocyte colony-stimulating factor support, constitutes a safe, tolerable, and convenient regimen for the treatment of MPM, suggesting that this combination may be a viable option, especially in previously treated patients.

Hypersensitivity reactions associated with platinum antineoplastic agents: a systematic review

Platinum-containing chemotherapy agents (cisplatin, carboplatin, oxaliplatin) have been approved in the first-line setting of numerous malignancies, such as ovarian, bladder, head and neck, colorectal, and lung cancer. Their extensive use over the last decade has led to a significant increase in the incidence of hypersensitivity reactions, which are defined as unforeseen reactions whose signs and symptoms cannot be explained by the known toxicity of these drugs. Skin rash, flushing, abdominal cramping, itchy palms, and back pain are common symptoms. Cardiovascular and respiratory complications can prove fatal. Multiple pathogenetic mechanisms have been suggested. Hypersensitivity usually appears after multiple infusions, suggesting type I allergic reactions; however, other types of hypersensitivity also seem to be implicated. Several management options are available to treating physicians: discontinuation of chemotherapy, premedication, prolonging of infusion duration, desensitization protocols, and replacement with a different platinum compound after performing skin tests that rule out cross-reactions among platinum agents.
