A 47-year old man had hypersplenism from massive splenomegaly, the cause of which was undetermined for 2 years. He was initially asymptomatic though there was mild pancytopenia. However, 18 months after presentation he manifested both clinical and haematological deterioration, almost succumbing to sepsis. Splenectomy finally provided a definite diagnosis of follicular lymphoma and also restored his blood counts to within normal range.

In an effort to reduce the risk of opportunistic infections, 25 patients with advanced indolent lymphoma (age range: 30-77 years) were treated, using a combination of fludarabine and mitoxantrone, without corticosteroids. Fludarabine was given at 25 mg/m2 for three daily doses, and mitoxantrone at 10 mg/m2. Cycles were repeated every four weeks for up to maximum response, and for no more than six months. Eight patients had follicular lymphoma, and 11 had CLL/SLL. Objective response was observed in 11 of 12 previously untreated patients, including five complete remissions, and in 10 of 13 previously treated patients, including three complete remissions. Only two relapsed patients failed to respond, whereas two patients were not evaluable. Hence, the overall response rate based on the intention-to-treat analysis was 84 per cent (95 per cent CI: 70-98 per cent). The median survival has not been reached after a 22-month follow-up. Median time to progression was 15 months. One patient on corticosteroids developed pneumocystis carinii pneumonia, and an elderly patient succumbed to neutropenic sepsis. Apart from granulocytopenia, the treatment was well tolerated. Omission of corticosteroids reduces the risk of opportunistic infections, while the activity of the combination against indolent lymphoma and CLL is maintained.

The purpose of this study was to evaluate the outcome and prognostic factors of patients with limited stage follicular non-Hodgkin's lymphoma treated prospectively by the Nebraska Lymphoma Study Group (NLSG). Forty previously untreated patients, median age 64 years, with limited stage follicular lymphoma were prospectively treated according to the protocols of the NLSG between January 1980 and December 1990. The follicular large cell type represents 75% of the cases, and 14 of the biopsies also had a diffuse component (composite lymphoma). The initial treatment was radiation therapy (RT) to the involved field in 15 patients, anthracycline-containing combination chemotherapy (CT) in 20, and combined RT and CT in 5. Thirty-seven patients (92.5%) achieved a complete remission (CR). The median follow-up is 120 months (range, 20 to 214). Of the 37 patients achieving a CR, 7 patients are alive in first CR, one died due to sepsis, another because of a myeloproliferative disorder at 77 months following chemotherapy, 6 died because of unrelated causes in first CR. Twenty-two patients relapsed between 1 to 128 months following a CR. The estimated 10-year event-free survival is 21% (95% CI: 7 to 35). Two patients received no or palliative therapy after relapse and both died of progressive disease. Nineteen patients received salvage therapy and 15 achieved a second remission. The median survival after first relapse is 55 months. The estimated 10-year overall survival is 44% (95% CI: 28 to 60). Various factors including sex, histologic subtype, stage, and degree of follicularity do not influence the overall survival or event-free survival. CT with or without RT resulted in a better trend for 10-year event-free survival in stage IA patients compared to RT alone but estimated 10-year overall survival is no different. The overall survival is worse in the > or = 60 age group but this difference is not evident if data is adjusted for cause specific death. In conclusion, limited stage follicular lymphoma has an excellent initial response to radiation therapy or chemotherapy; however the recurrence rate is high and cure is limited.

The role of high dose therapy, including autologous stem cell transplantation (ASCT) in indolent non-Hodgkin's lymphomas remains controversial. We evaluated a dose intense regimen of CHOP induction followed by high dose cyclophosphamide consolidation (CHOP-HC) versus CHOP alone in a prospective comparison to assess intensified therapy without ASCT. Twenty-five patients with previously untreated advanced stage indolent NHL were enrolled: follicular lymphoma, grade 1 (11 patients) and grade 2 (8 patients); small lymphocytic lymphoma (5 patients); and lymphoplasmacytic lymphoma (1 patient). All patients were treated as clinically indicated. The median age was 47 years (21-70). There were 15 males, and 10 females. Three patients had intra-abdominal stage II, 2 patients with stage III, and 20 patients with stage IV disease. All patients received induction with CHOP for 4 cycles (weeks 1, 4, 7, 10): cyclophosphamide 750 mg/m2 i.v., doxorubicin 50 mg/m2 i.v., vincristine 1.4 mg/m2 i.v. (2 mg capped dose) and prednisone 100 mg p.o. x 5 days. Following induction, responding patients were given consolidation with either high dose cyclophosphamide @ 3 gm/m2 i.v. for 3 doses with G-CSF (weeks 13, 15, 17) or 2 additional cycles of CHOP (weeks 13, 16), stratified by stage and bulk of disease. The overall response rate to CHOP was 92% (3 CR, 8 PR) and to CHOP-HC was 93% (4 CR, 8 PR). The overall response, complete response and partial response rates were comparable in both arms. Median progression free survival for CHOP was 15.9 and 23.0 months for CHOP-HC. At 74.3 months median follow-up, all patients in the CHOP arm have recurred; 3 patients in the CHOP-HC arm (3 CR) have not recurred. The median overall survival has not been reached (at 5 years, 77% OS for CHOP-HC versus 83% OS for CHOP alone]. Greater hematologic toxicity was observed with CHOP-HC resulting in an increased number of hospitalizations for sepsis. There were no treatment-related deaths. No myelodysplasia or acute leukemia has been seen to date. With no obvious improvement in CR and with greater hematologic toxicity than CHOP, CHOP-HC is not recommended for treatment of indolent non-Hodgkin's lymphomas.

A phase I study of irinotecan hydrochloride (CPT-11), carboplatin, and dexamethasone treatment in 7 patients with relapsed lymphoma and 7 patients with refractory lymphoma was conducted to evaluate the maximal tolerated dose. The 6 female and 8 male patients had a median age of 63 years (range, 45-73 years), a median performance status of 0 (range, 0-2), and a median disease stage of IV. This study included patients with diffuse large B-cell lymphoma (n = 5), adult T-cell leukemia/lymphoma (n = 2), mantle cell lymphoma (n = 2), follicular lymphoma (n = 2), angioimmunoblastic T-cell lymphoma (n = 1), anaplastic large cell lymphoma (n = 1), and Hodgkin's lymphoma (n = 1). All patients had received anthracycline-containing combination chemotherapy prior to this therapy. The starting dosage of CPT-11 was 15 mg/m2 per day (days 1-3 and 8-10), and dosage-escalation increments of 5 mg/m2 per day were planned, with fixed dosages of carboplatin (250 mg/m2 per day, day 1) and dexamethasone (40 mg/body, days 1-3 and days 8-10). Five patients were enrolled at level 1, 3 at level 2, 4 at level 3, and 2 at level 4. Ten patients (71%) and 11 patients (79%) experienced grade 3 or 4 hematologic toxicities of leukocytopenia and neutropenia, respectively. Three patients (29%) and 9 patients (64%) experienced grade 3 or 4 thrombocytopenia and anemia, respectively. Two patients who received 30 mg/m2 (level 4) of CPT-11 developed sepsis. We concluded that the recommended dose of CPT-11 with carboplatin and dexamethasone is 25 mg/m2. No deaths were related to this chemotherapy, and no patient developed liver dysfunction. The overall response rate was 36%. We conclude that the combination therapy of CPT-11, carboplatin, and dexamthasone is effective as salvage therapy but that the duration of response is too short.

The therapy of patients with relapsed or refractory indolent lymphoma relies on the development of new drug combinations. The drugs bendamustine and fludarabine have cytotoxic activity as monotherapy in indolent lymphoma and show synergism in vitro. In this study, we combined both drugs in a multicenter clinical phase I/II trial to evaluate their toxicity and efficacy. Bendamustine was given at 30 or 40 mg/m2/d (dose levels 1 and 2), fludarabine at 30 mg/m2/d, each drug on days 1 to 3. Six cycles were to be given every 4 weeks. A total of 29 patients with relapsed or refractory indolent lymphoma were included in the study. During phase I, 9 patients were treated at dose level 1 and 7 patients at dose level 2. Thirteen patients were added to the study during phase II. Fourteen patients had follicular lymphoma, 11 patients mantle cell lymphoma, 2 patients lymphoplasmocytic and 2 patients nodal marginal zone lymphoma. Median age was 62 years (range 39-74). All patients were in stages III or IV of their disease and had received prior chemotherapy with or without additional radio- or immunotherapy. The dose limiting toxicity was hematotoxicity in all cases and occurred in 3 of 7 evaluable patients at dose level I and in 3 of 7 patients at dose level 2. One patient at dose level 2 died of sepsis in neutropenia with persistent thrombocytopenia. The study was continued at dose level 1 (phase II). Analysis of 19 evaluable patients treated at dose level 1 reveiled hematotoxicity CTC grade III in 47% and grade IV in 26%. Neutropenic fever occurred in 4 patients (21%). On an intent-to-treat basis, 45% or 32% of all patients at dose level 1 reached CR or PR, respectively. Nine of 9 patients with mantle cell lymphoma responded to therapy. The overall response rate was 77%. Eight of 15 responders relapsed after a median follow-up time of 14 months (range 2-43). The major complication of fludarabine in combination with bendamustine is hematotoxicity. Dose level 1 with 30 mg/m2/d of both drugs on days 1 to 3 was defined as the recommended dose. Despite unfavorable prognostic features (histologic subtype, stage of disease, pretreatment) response rates were good with this regimen.

Paraneoplastic pemphigus (PNP) is an autoimmune blistering disease with poor prognosis when associated with malignant neoplasm. We report the case of a patient with PNP associated with a CD20+ non-Hodgkin follicular lymphoma who was treated with Rituximab plus corticosteroids and short courses of cyclosporin. One and a half years after Rituximab therapy, oral ulcerations had cleared and oral methylprednisolone was slowly tapered down without further recurrences. In the course of the disease, the patient developed sepsis due to Listeria monocytogenes and viral infections by human herpes virus 1 and 3. At the end-stage of the disease she developed a cutaneous infection from Mycobacterium chelonae. The patient died 2 years and 7 months after the onset of PNP. Rituximab may be useful for PNP therapy, but further studies are necessary to confirm this hypothesis.

High-dose chemotherapy with autologous SCT has become standard of care for patients with relapsed aggressive non-Hodgkin's lymphoma (NHL). To improve safety and efficacy of this treatment, new conditioning regimens are being developed. We retrospectively reviewed clinical data of patients with relapsed NHL treated at our institution with i.v. BU and CY (BU/CY) as conditioning regimen for autologous SCT between January 2000 and April 2005. We identified 43 patients (24 men, 19 women, median age 50) with diffuse large B-cell lymphoma (n=28), follicular lymphoma (n=8), mantle cell lymphoma (n=4) and peripheral T-cell lymphoma (n=3). Following salvage chemotherapy, there were 26 complete responses, 13 partial responses and 4 stable diseases. Median time to neutrophil and platelet recovery was 11 and 13.5 days, respectively. Treatment-related toxicities included nausea/vomiting, diarrhea and mucositis. The 100-day mortality was 9%: sepsis (n=1), pneumonia (n=1) and hepatic veno-occlusive disease (n=2). Twenty-one patients were followed until death and twenty-one surviving patients were followed for a median of 29 months (range 0.4-76). Three-year estimates of event-free survival, progression-free survival and overall survival were 35, 39 and 43%, respectively. We conclude that i.v. BU/CY is a safe and effective conditioning regimen for autologous SCT in relapsed NHL.

On July 23, 2014, the FDA granted accelerated approval to idelalisib (Zydelig tablets; Gilead Sciences, Inc.) for the treatment of patients with relapsed follicular B-cell non-Hodgkin lymphoma or relapsed small lymphocytic lymphoma (SLL) who have received at least two prior systemic therapies. In a multicenter, single-arm trial, 123 patients with relapsed indolent non-Hodgkin lymphomas received idelalisib, 150 mg orally twice daily. In patients with follicular lymphoma, the overall response rate (ORR) was 54%, and the median duration of response (DOR) was not evaluable; median follow-up was 8.1 months. In patients with SLL, the ORR was 58% and the median DOR was 11.9 months. One-half of patients experienced a serious adverse reaction of pneumonia, pyrexia, sepsis, febrile neutropenia, diarrhea, or pneumonitis. Other common adverse reactions were abdominal pain, nausea, fatigue, cough, dyspnea, and rash. Common treatment-emergent laboratory abnormalities were elevations in alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, absolute lymphocytes, and triglycerides. Continued approval may be contingent upon verification of clinical benefit in confirmatory trials.

Ceftazidime-avibactam and ceftolozane-tazobactam are new antimicrobials with activity against multidrug-resistant Pseudomonas aeruginosa. We present the first case of persistent P. aeruginosa bacteremia with in vitro resistance to these novel antimicrobials. A 68-year-old man with newly diagnosed follicular lymphoma was admitted to the medical intensive care unit for sepsis and right lower extremity cellulitis. The patient was placed empirically on vancomycin and piperacillin-tazobactam. Blood cultures from Day 1 of hospitalization grew P. aeruginosa susceptible to piperacillin-tazobactam and cefepime identified using VITEK 2 (Biomerieux, Lenexa, KS). Repeat blood cultures from Day 5 grew P. aeruginosa resistant to all cephalosporins, as well as to meropenem by Day 10. Susceptibility testing performed by measuring minimum inhibitory concentration by E-test (Biomerieux, Lenexa, KS) revealed that blood cultures from Day 10 were resistant to ceftazidime-avibactam and ceftolozane-tazobactam. The Verigene Blood Culture-Gram-Negative (BC-GN) microarray-based assay (Nanosphere, Inc., Northbrook, IL) was used to investigate underlying resistance mechanism in the P. aeruginosa isolate but CTX-M, KPC, NDM, VIM, IMP, and OXA gene were not detected. This case report highlights the well-documented phenomenon of antimicrobial resistance development in P. aeruginosa even during the course of appropriate antibiotic therapy. In the era of increasing multidrug-resistant organisms, routine susceptibility testing of P. aeruginosa to ceftazidime-avibactam and ceftolozane-tazobactam is warranted. Emerging resistance mechanisms to these novel antibiotics need to be further investigated.
