[Targeted therapies in digestive oncology].

Targeted therapies have an increasing importance in digestive oncology. These new treatments have been authorized in colon cancer, gastric cancer, pancreatic cancer, endocrine cancer and gastrointestinal stromal tumors. The oncologist should develop high abilities to use these therapies especially concerning the indications, response's biomarkers, toxicities and evaluation methods.

Long-term disease-free survivors in metastatic undifferentiated carcinoma of nasopharyngeal type.

Purpose: To review incidence and analyze profile of long-term complete responders among patients with undifferentiated carcinoma of nasopharyngeal type (UCNT) treated at a single institution.

Patients And Methods: We present a cohort of 20 long-term unmaintained complete responders to chemotherapy for metastatic UCNT treated at the Institut Gustave Roussy between April 1978 and November 1996. A patient was considered a long-term survivor if he or she was disease-free for more than 36 months without treatment after obtaining a complete response by chemotherapy.

Palliative treatment with low-dose continuous infusion 5-fluorouracil in recurrent and/or metastatic undifferentiated nasopharyngeal carcinoma type.

Background: Low-dose protracted continuous infusion (CI) 5-fluorouracil (5-FU), as proposed by Lokich et al, has been reported to be active and well tolerated in colorectal and breast cancers. We initiated a phase II trial with CI 5-FU in heavily pretreated undifferentiated carcinoma of the nasopharyngeal type (UCNT) patients in February 1989.

Methods: Twenty-one UCNT patients with recurrent and/or metastatic disease were treated with CI 5-FU (300 mg/m2) for 6 consecutive weeks.

Final report of a phase II study of chemotherapy with bleomycin, epirubicin, and cisplatin for locally advanced and metastatic/recurrent undifferentiated carcinoma of the nasopharyngeal type.

Purpose: This article presents an assessment of the combination of bleomycin, epirubicin, and cisplatin as induction chemotherapy before radiotherapy in the treatment of undifferentiated carcinoma of the nasopharyngeal type in patients with recurrent/metastatic disease (group A), and in previously untreated patients with locoregionally advanced disease (UICC-AJCC 87, N2-3, M0) (group B) in terms of toxicity, antitumoral activity, and therapeutic efficacy.

Patients And Methods: From January 1987 to September 1990, 111 consecutive patients with histologically proven UCNT were treated with six cycles of intravenous cisplatin (100 mg/m2 day 1) epirubicin (80 mg/m2 day 1), and bleomycin (15 mg bolus day 1), followed by 16 mg/m2/day continuous infusion for 5 days, repeated every 21 days for three cycles. Three further cycles without bleomycin were given to 44 patients in group A.

Leukemoid reaction, bone marrow invasion, fever of unknown origin, and metastatic pattern in the natural history of advanced undifferentiated carcinoma of nasopharyngeal type: a review of 255 consecutive cases.

Purpose: This study is an analysis of frequency and relationship regarding two undifferentiated carcinoma of nasopharyngeal type (UCNT)-associated paraneoplastic syndromes (PNS): leukemoid reaction (LR) and fever of unknown origin (FUO) with bone marrow invasion (BMI) and metastatic pattern.

Patients And Methods: A consecutive UCNT patient cohort (N = 255) with locally advanced (n = 142) or metastatic (n = 113) disease receiving chemotherapy alone or in combination with radiotherapy was studied. All patients had a complete baseline work-up that included bone marrow biopsy.
