Alternating triple therapy for the treatment of intermediate grade and immunoblastic lymphoma

Primary Hepatic Diffuse Large B-cell Lymphoma Mimicking Acute Fulminant Hepatitis: A Case Report and Review of the Literature

Primary hepatic lymphoma (PHL) is a rare variant of non-Hodgkin's lymphoma. Diffuse hepatic involvement is uncommon and therefore presentation as progressive hepatitis or acute fulminant hepatic failure is rare. Acute onset of signs and symptoms can mimic a variety of infectious and inflammatory disorders, thus delaying the diagnosis. A high index of suspicion and liver biopsy early in the course of liver dysfunction may establish the diagnosis and allow rapid initiation of chemotherapy to prevent a fatal outcome. In this report, we describe a rare case of fulminant primary hepatic diffuse large B-cell lymphoma in a 55-year-old woman who died 2 weeks after admission, before the initiation of chemotherapy.

LEARNING POINTS

Primary hepatic lymphoma (PHL) is a rare yet serious disease which should be suspected in every case presenting as hepatitis with unclear aetiology.A liver biopsy should be performed as early as possible when PHL is suspected.Failure to detect PHL early can result in rapid deterioration and death within 2 weeks of presentation.

The survival outcome of patients with relapsed/refractory peripheral T-cell lymphoma-not otherwise specified and angioimmunoblastic T-cell lymphoma

Survival outcome of patients with peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) and angioimmunoblastic T-cell lymphoma (AITL) who experience disease progression/relapse remains very poor. A total of 321 patients, newly diagnosed with PTCL-NOS (n = 180) or AITL (n = 141) between 1999 and 2015, were analysed. Failure-free survival (FFS) and overall survival (OS) were calculated from the time of first disease progression (FFS1, OS1), from second disease progression (FFS2, OS2) and from third progression (FFS3, OS3). With a median follow-up duration of 52 months, 240 patients (135 PTCL-NOS, 105 AITL) experienced progression/relapse. In patients with PTCL-NOS, the median durations of FFS1, FFS2 and FFS3 were 3·1, 2·5 and 2·1 months, respectively. In patients with AITL, they were 5·5, 2·9 and 2·3 months, respectively. There was no improvement in FFS1 and OS1 by the time of recurrence during this period (1999-2004, 2005-2009 and 2010-2015). The median FFS after pralatrexate and romidepsin was only 3·0 and 2·5 months, respectively. The 5-year OS rates after salvage autologous and allogeneic transplant were 32% and 52%, respectively; while the 5-year OS rates for patients who did not undergo transplant was 10%. Further research for novel therapeutic approaches with higher efficacy and better safety profile are needed.

Phase II study of HCVIDD/MA in patients with newly diagnosed peripheral T-cell lymphoma

A phase II study was performed to evaluate the efficacy of hyper-fractionated cyclophosphamide, vincristine, pegylated liposomal doxorubicin and dexamethasone alternating with methotrexate/cytarabine (HCVIDD/MA) in patients with newly diagnosed peripheral T-cell lymphoma (PTCL), excluding ALK-positive anaplastic large cell lymphoma. Fifty-three patients were enrolled. Treatment was planned for up to 8 cycles but only 9% of patients received more than 6 cycles due primarily to disease progression (n = 13) or prolonged thrombocytopenia (n = 12). The overall response rate was 66% with a complete response rate of 57%. Median progression-free survival (PFS) was 7·5 months. With a median follow-up of 7·6 years, 5-year PFS and overall survival (OS) were 21% and 48%, respectively. The patients with extranodal Natural Killer-cell lymphoma had a shorter PFS (median, 2·4 months) than other subtypes. Grade 3/4 anaemia, neutropenia and thrombocytopenia were observed in 66%, 74% and 79% of patients, respectively. Of note, 23% of patients discontinued therapy due to prolonged thrombocytopenia. In conclusion, HCVIDD/MA for the first-line treatment of PTCL patients is associated with significant myelosuppression leading to poor treatment adherence, and the response and survival outcomes with this regimen are similar to standard CHOP. This study was registered at www.clinicaltrials.gov as #NCT00290433.

Primary T-cell lymphoma of liver

Primary hepatic lymphoma (PHL) is rare and represents approximately 0.016% of all cases of non-Hodgkin's lymphoma (NHL). The majority of these are B-cell NHL of diffuse large B-cell type. Primary T-cell lymphoma constitutes approximately 5-10% of all PHLs arising in the liver, 90% being B-cell type. Peripheral T-cell lymphoma, γδ hepatosplenic T-cell lymphoma and αβ hepatosplenic T-cell lymphoma are the common T-cell lymphomas involving hepatic parenchyma. We encountered a case presenting with gross hepatomegaly extending beyond umbilicus, mild ascites, pedal oedema, icterus and dyspnoea. Haemogram showed moderate anaemia with counts. Bone marrow aspiration showed erythroid hyperplasia with dimorphic anaemia. There was no evidence of atypical lymphoid cells in peripheral blood of bone marrow. We present a rare case of primary T-cell lymphoma presenting as primary liver involvement without splenomegaly, lymphadenopathy, bone marrow or peripheral blood involvement.

Non-Hodgkin's lymphoma involving the liver: clinical and therapeutic considerations

Primary hepatic non-Hodgkin's lymphoma (NHL) is a rare disease that presents unique diagnostic and therapeutic challenges. Secondary liver involvement by lymphoma is common and can complicate treatment decisions. A review of the published case reports and the few larger series suggests that primary hepatic NHL represents a heterogeneous mixture of disparate diseases rather than a single entity. Presentations vary from the incidental discovery of hepatic abnormalities in an otherwise asymptomatic patient to that of fulminant hepatic failure with rapid progression of encephalopathy to coma and death. The clinical, laboratory, and radiographic characteristics are nonspecific, which means the diagnosis is often not suspected until histopathologic examination of liver tissue. There appears to be a strong association between primary hepatic NHL and the hepatitis C virus. Hepatosplenic T-cell lymphoma has attained its own status as a unique disease, whereas case reports suggest that the spectrum of hepatic lymphoma includes many histologies. Involvement of the liver by lymphoma can compound the difficulty of pursuing aggressive chemotherapy in patients who have a life-threatening illness and impaired metabolism of the most effective drugs. Therapy should be tailored to the individual clinical situation, with consideration of the underlying histology and degree of hepatic insufficiency.

Ifosfamide in hematological malignancies of adults

Ifosfamide is an alkylating agent with a broad spectrum of activity in solid tumors and hematological malignancies. In this review we will illustrate its use in the treatment of lymphomas and Hodgkin's disease and the results of the principal studies which have investigated ifosfamide-containing regimens. Ifosfamide has been mainly used, in combination with other drugs, as a component of salvage regimens for relapsed or primarily refractory lymphoma. These regimens induced a variable clinical response rate (complete remissions ranging from 6 up to 73% and overall response rate from 24 to 72%). High-dose ifosfamide, in combination with etoposide or mitoxantrone, showed a good potential for mobilization of peripheral stem cells while reducing the tumor burden. Ifosfamide-based regimens are also being evaluated in the treatment of newly diagnosed patients in sequential, response-based protocols, using many non-cross-resistant drugs.

Soluble intercellular adhesion molecule-1 (s-ICAM-1/s-CD54) in diffuse large B-cell lymphoma: association with clinical characteristics and outcome

BACKGROUND

High serum levels of soluble intercellular adhesion molecule-1(s-ICAM-1/s-CD54) have been associated with adverse clinical features and poor outcome in chronic lymphocytic leukemia, Hodgkin's disease and non-Hodgkin's lymphoma, but their value in the different subtypes of non-Hodgkin's lymphoma has not been well addressed.

PATIENTS AND METHODS

Our aim was to study the serum levels of s-ICAM-1 in diffuse large B-cell lymphoma (DLBCL) and to correlate them with clinical characteristics and outcome. We analyzed the serum levels of s-ICAM-1 in a series of 55 patients with DLBCL diagnosed in a single institution. s-ICAM-1 levels were quantified by an immunoenzymatic assay. Median age was 62 years (range 22-96); 29 (53%) were male. Twenty-eight (51%) presented with advanced clinical stage (III/IV), 32 (58%) had extranodal involvement, 28 (51%) had high serum lactate dehydrogenase (LDH) and 23 (43%) had high beta2-microglobulin levels. All patients received anthracycline-containing regimens. Correlation between clinical variables and s-ICAM-1 levels were tested with the Mann-Whitney U-test and survival was plotted by the Kaplan-Meier method, and curves compared with the log-rank test.

RESULTS

Serum levels of s-ICAM-1 were significantly increased in patients with DLBCL compared with normal controls (589 +/- 487 versus 279 +/- 65 ng/ml, respectively; P <0.001). Higher levels of s-ICAM-1 were present in patients with B symptoms, advanced stage and increased LDH and beta2-microglobulin. s-ICAM-1 levels also correlated with achievement of a complete response. Patients with s-ICAM-1 over 668 ng/ml had a shorter time to treatment failure (TTF) (3-year TTF, 59% versus 20%, respectively; P = 0.01) and overall survival (OS) (3-year OS, 58% versus 22%, respectively; P = 0.04) than the remainders. When only low and low-intermediate risk patients in the international prognostic index score were considered, those with s-ICAM-1 over 668 ng/ml also had worse TTF and OS.

CONCLUSIONS

In DLBCL, s-ICAM-1 levels correlated with high tumor burden and lymphoma dissemination and may contribute to assessment of prognosis.

Primary cutaneous non-Hodgkin's lymphoma with aggressive histology: inferior outcome is associated with peripheral T-cell type and elevated lactate dehydrogenase, but not extent of cutaneous involvement

BACKGROUND

The aim of this study was to explore the association between extent of cutaneous involvement, presenting features and progression-free survival (PFS) in patients with primary cutaneous non-Hodgkin's lymphoma (PCNHL) of aggressive histology.

METHODS

Previously untreated patients with localized or extensive PCNHL of aggressive histology, treated with combination chemotherapy, but excluding lymphoblastic lymphoma and mycosis fungoides and its variants, were reviewed retrospectively.

RESULTS

We identified 53 patients, of whom 52 (35 males, 17 females) were treated with doxorubicin-based regimens. Median age was 52 years (range 25-81 years), and disease was localized and extensive in 37 and 16 patients, respectively. Twenty-four patients had diffuse large B-cell lymphoma, nine had grade 3 follicular lymphoma, 13 had peripheral T-cell lymphoma (PTCL; not otherwise specified) and seven had anaplastic large cell lymphoma (WHO classification). With a median follow-up of 101 months (range 2-237 months) for survivors, the 10-year PFS was 65 +/- 7% and overall survival was 72 +/- 8%. The first failure involved the skin in 33% of B-cell and 91% of relapsing T-cell lymphomas. Univariate analysis revealed that PTCL (P = 0.005), lymphopenia (P = 0.01) and high serum levels of beta(2)-microglobulin (P = 0.0006) and LDH (P = 0.002), but not extent of skin involvement, were associated with inferior PFS. Multivariate analysis revealed that only PTCL and high serum lactate dehydrogenase (LDH) were independently associated with inferior PFS.

CONCLUSIONS

PTCL and elevated serum LDH level, but not extent of cutaneous involvement are associated with inferior PFS in aggressive PCNHL treated with combination chemotherapy.

Clinical presentation and treatment of secondary orbital lymphoma

PURPOSE

To describe the clinical features and histologic classification of orbital lymphoma secondary to systemic non-Hodgkin lymphoma, to evaluate the efficacy of various treatment modalities for controlling the orbital component of disease, and to analyze vision-related outcomes.

METHODS

In this retrospective case series, the clinical records of patients diagnosed with orbital lymphoma who were treated between January 1999 and May 2001 at the University of Texas M.D. Anderson Cancer Center were reviewed. Demographic data, histologic classification of lymphoma, immunophenotype, stage of disease, treatment outcomes, vision-related outcomes, and duration of follow-up after the diagnosis of orbital lymphoma were recorded in each case.

RESULTS

At the time of diagnosis, all 15 patients identified either had a previous history of non-Hodgkin lymphoma or had simultaneous involvement of lymph node or other sites. Ten patients (67%) had intermediate-grade or high-grade lymphoma. All 15 patients had a B-cell phenotype. Systemic chemotherapy or immunotherapy was the initial treatment modality in 13 patients; the other 2 patients were treated with radiation as the initial mode of therapy. Eleven patients (73%) achieved complete regression of the orbital tumor; one patient had partial regression of the orbital lymphoma. Loss of vision secondary to compressive optic neuropathy was seen in 5 patients (33%); in 3 of these patients, the orbital lymphoma was diagnosed early and treatment was successful in reversing the loss of vision. One patient had irreversible vision loss secondary to compressive optic neuropathy; in this case, therapy had not been initiated until several months after onset of symptoms. Another patient died of lymphoma before the orbital disease could have responded to therapy.

CONCLUSIONS

Because of often widespread systemic involvement and a usually more aggressive histologic classification than primary orbital lymphomas, secondary orbital lymphomas warrant treatment with systemic chemotherapy or systemic immunotherapy. In some cases, combining such systemic therapy with local radiation treatment is beneficial. Loss of vision as the result of compressive optic neuropathy in this setting can be reversed if systemic therapy is initiated soon after the onset of progressive signs and symptoms of orbital disease.

High-dose therapy for indolent lymphoma

Stem-cell transplantation (SCT) has become the treatment of choice for patients with relapsed aggressive non-Hodgkin's lymphoma (NHL). However, the role of SCT in the management of patients with indolent NHL remains controversial. Indolent follicular lymphomas are diseases which are generally incurable with conventional therapy. Although patients can survive for prolonged periods, the median duration of first remission is approximately 3 years, and subsequent remissions are progressively shorter with time. Emerging evidence suggests that high-dose chemotherapy with SCT leads to prolonged disease-free and overall survival in a subset of patients with indolent NHL. However, there is increasing concern regarding the toxicity of SCT, especially the long-term risk of developing myelodysplastic syndrome. It is still unclear as to when this approach should be used. Poorer outcomes have been obtained in heavily pretreated patients but encouraging results are being reported for patients undergoing SCT early during the course of their disease. Investigators are now focusing on how to improve SCT efficacy in order to eradicate minimal residual disease. Many ongoing studies are especially exploring the impact of stem-cell purging and novel ablative regimens combined with allogeneic transplantation.

Primary hepatic lymphoma: favorable outcome after combination chemotherapy

BACKGROUND

Primary hepatic non-Hodgkin lymphoma (PHL) is a rare and difficult to diagnose lymphoproliferative disorder of unknown etiology. It is believed that the prognosis in affected patients is dismal, consisting of early recurrence and short survival.

METHODS

A retrospective cohort review of patients with PHL diagnosed between 1974 and 1995 at a university cancer center was performed.

RESULTS

Twenty-four patients with PHL were identified. Typically, the disease occurred in middle-aged men (median age, 50 years). The primary presenting complaint was right upper quadrant abdominal pain, with hepatomegaly found at physical examination. Serum liver enzymes, lactate dehydrogenase, and beta-2-microglobulin levels all were elevated, but alpha-fetoprotein and carcinoembryonic antigen levels were within normal range. Hypercalcemia was found in 6 of 15 patients who were tested. Six of 10 patients who were tested were positive for the hepatitis C virus (HCV). Liver scans demonstrated either a solitary lesion or multiple lesions. Pathologic examination revealed diffuse large cell lymphoma in 23 patients (96%). Combination chemotherapy was the mainstay of treatment; surgery consisted of diagnostic biopsy. The complete remission rate was 83.3%, and the 5-year cause specific and failure free survival rates were 87.1% and 70.1%, respectively. HCV infection did not appear to influence the outcome of therapy.

CONCLUSIONS

The outcome of patients with PHL who are treated with combination chemotherapy may be more favorable than that reported elsewhere. The frequent association of PHL with HCV infection observed in this series warrants further investigation.

Non-Hodgkin's lymphoma affecting the testis: is it curable with doxorubicin-based therapy?

This study was designed to determine response, outcome, and patterns of failure of patients with non-Hodgkin's lymphoma who presented with a testicular mass. Consecutive patients presenting to M.D. Anderson Cancer Center between 1969 and 1999 treated with doxorubicin-based regimens and with radiotherapy and/or intrathecal therapy were considered for this study. We identified 43 patients whose median age was 61 years. Ann Arbor stage (AAS) was I in 22 patients, II in 7 patients, III in 1 patient, and IV in 13 patients. All 43 patients had intermediate-grade lymphomas according to the Working Formulation, and all 31 tumors assessed immunophenotypically were large B-cell lymphoma according to the World Health Organization classification. The International Prognostic Index score was > or = 2 in 18 patients (42%). Thirty-four patients achieved complete remission, 19 of whom relapsed, and 5 failed initial therapy. At 10 years, progression-free survival (PFS) was 20% +/- 9% and survival was 33% +/- 9%. Progression-free survival for patients with AAS I/II vs. III/IV was 36% +/- 13% vs. 0%, respectively (P = 0.004). At 10 years, the actuarial probability of failure in the central nervous system was 34% +/- 9% and was 21% +/- 9% in contralateral testis. Using the intent-to-treat method, patients receiving cyclophosphamide/doxorubicin/ vincristine/prednisone (CHOP), with additional scrotal radiotherapy and intrathecal methotrexate, had a 5-year PFS of 91% +/- 9% vs. 30% +/- 15% vs. 41% +/- 12% for those receiving only one or neither of these additional modalities (P = 0.053). Doxorubicin-based regimens alone appear unable to cure most patients with lymphoma involving the testis, but CHOP with prophylactic intrathecal therapy and adjuvant scrotal radiotherapy appears promising. This should be confirmed with prospective clinical trials and longer follow-up.

Primary cutaneous non-Hodgkin's lymphoma of Ann Arbor stage I: preferential cutaneous relapses but high cure rate with doxorubicin-based therapy

PURPOSE

Establish frequency, presenting features, response and relapse patterns, and outcome of primary cutaneous non-Hodgkin's lymphoma (PCNHL).

PATIENTS AND METHODS

Review of untreated patients, older than 16 years, presenting between 1971 and 1993 with cutaneous lymphoma, not mycosis fungoides, and Ann Arbor stage I.

RESULTS

We identified 46 patients, 27 males, with median age of 57 years. Treatment was radiotherapy in 10 patients, doxorubicin-based therapy in 33 patients that was followed by radiotherapy in 25 patients, and other combination with radiotherapy in one patient. The complete response rate was 95%. After a median follow-up of 140 months (range, 61 to 284 months), 18 patients have relapsed, and 14 have died from lymphoma. The first failure was exclusively cutaneous in 50% of relapses. For the 44 treated patients, progression-free survival (PFS; actuarial +/- SE) was 61% +/- 7% and survival was 58% +/- 9% at 12 years. For the 18 patients with diffuse large B-cell lymphoma, after doxorubicin-based regimens, PFS was 71% +/- 12% (P = .0003) versus 0% after radiotherapy; survival was 77% +/- 12% versus 25% +/- 22% (P = 004), respectively. For the nine patients with follicular center-cell lymphoma treated with combined modality, the 12-year PFS was 89% +/- 11% and survival 70% +/- 18%.

CONCLUSION

PCNHL is rare, and its first relapse is exclusively cutaneous in 50% of patients. Patients with diffuse large B-cell lymphoma are curable with doxorubicin-based regimens but not with radiotherapy. Prospective studies in PCNHL should define the cytogenetics, the basis for cutaneous tropism, the prognosis of histologic subtypes, and the role of radiotherapy.
