We retrospectively analyzed overall survival and survival after progression in 91 patients with low-grade follicular lymphoma (LGFL). Histological subtype was B in 75 patients and C in 16 patients. Twelve patients with localized disease received involved-field radiotherapy; seven patients without bulky disease had no initial therapy. The remaining 72 patients received long-term chlorambucil (9 patients), MOPP or COPBleo (42 patients), or a CHOP-derived regimen (21 patients). Forty-two patients (46%) achieved a complete remission (CR) and 28 patients (31%) achieved a partial remission; 48 of these 70 patients relapsed or progressed. Nineteen of the other 21 patients with stable LGFL progressed. Two other patients failed to respond and rapidly died. Thirty-two of the 67 patients with progressive or relapsed LGFL have died. Median overall survival was 111 months. Age > or = 70 years, male sex, B symptoms, histological subtype follicular mixed-cell NHL, tumor size > or = 10 cm, number of extranodal sites of disease > or = 2, pleural effusion, and Ann Arbor stage III or IV were found to adversely influence overall survival. Failure-free survival < 24 months, failure to achieve a CR after the progression, initial histological subtype follicular mixed cell, initial Ann Arbor stage III or IV, and initial tumoral size > or = 10 cm were found to adversely influence survival after progression. Our results suggest that most prognostic factors for overall survival in LGFL are related to histological subtype or tumor burden. Some initial adverse prognostic factors for survival may be also associated with a poor survival after progression.

We evaluated with an intent-to-treat analysis the response rate, the disease-free survival (DFS), and the overall survival after a multidrug salvage regimen (VIM3ARAC), followed by stem-cell transplantation (SCT) in case of response, in patients with aggressive non-Hodgkin's lymphoma (NHL) who progressed on or after the first-line therapy. Seventy-one patients (refractory: 15; relapse 'on therapy': 36; and relapse 'off therapy': 20) received two courses of VIM3ARAC (teniposide, ifosfamide, mitoxantrone, mitoguazone, high-dose methotrexate, high-dose cytarabine, prednisolone). SCT was performed only in patients with minimal disease after the second course. The response rate was 72%. It was not influenced by response to first-line therapy. Forty-eight patients (68%), including 32 complete responders, fulfilled response criteria for SCT. Thirty-six patients underwent SCT (allogeneic: 3; autologous: 33). The 4-year DFS rate of the 48 responding patients was 39%. The actuarial survival at 4 years was 34% for all patients. Relapse off therapy and a performance status Ͻ2 at relapse were the only two independent favorable prognostic factors for survival. In conclusion, VIM3AraC is associated with a high response rate in relapsing and refractory aggressive NHL. Up to half of the patients could receive SCT. This chemotherapy, followed by SCT could durably salvage 34% of these patients.

An outbreak of rectal lymphogranuloma venereum (LGV) has been reported since 2003 in men who have sex with men, most of them being infected with human immunodeficiency virus. In these patients, unusual clinical presentations such as rectal tumor or intense lymphoproliferation on rectal biopsies may lead to an erroneous diagnosis of aggressive non-Hodgkin lymphoma. Three patients were referred to our center for the management of rectal B-cell non-Hodgkin lymphoma on the basis of a rectal pathologic specimen showing intense lymphoproliferation, the very suspect of lymphoma. Because of anamnesis of anal intercourses and venereal diseases, additional study revealed that all 3 had a positive Chlamydia trachomatis polymerase chain reaction on the rectal biopsy specimen. Rectal LGV was therefore considered and successfully treated with antibiotics. We propose that all patients presenting with a suspected rectal lymphoma should have a careful anamnesis of sexual behavior and a specific detection of C. trachomatis using polymerase chain reaction analysis on biopsy specimen to rule out the possibility of rectal LGV.
