Abstract:
Although most lymphoma subtypes have been reported in the eye, [1] the vast majority of ocular lymphomas are non-Hodgkin lymphomas (NHLs) of B-cell type; a small minority (1%–2%) are derived from T-lymphocytes or natural killer cells. [1] Here, we report a rare case of conjunctival peripheral T-cell lymphoma not otherwise specified (PTCL NOS) in a 47-year-old female. Slit-lamp examination showed salmon-colored limbal thickening of the conjunctiva, characteristic of conjunctival lymphoma. This was associated with bone marrow and lymph node involvement. The lymphoma was treated with six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy, followed by consolidation with autologous hematopoietic stem cell transplantation, resulting in durable complete systemic and conjunctival remission at 6 months of follow-up. Conjunctival T-cell lymphoma can present with minimal and nonspecific symptoms, making it imperative for the clinician to consider ocular lymphoma when presented with unexplained conjunctivitis.Keywords:

The occurrence of B-cell lymphoma with intermediate- to high-grade features and different immunophenotypic profiles involving separate anatomic sites is uncommon. We describe such a case and present results of ancillary studies that characterized this B-cell lymphoma. The patient was treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) and intrathecal methotrexate with a good clinical response.

Hypoxia-inducible factor-1α (HIF-1α) has been identified as an unfavorable prognostic factor in most solid tumors. However, HIF-1α was suggested to predict improved survival in Western patients with diffuse large B-cell lymphoma (DLBCL) under rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) treatment. We studied HIF-1α protein expression by immunohistochemical staining of 155 paraffin-embedded specimens from Chinese patients with DLBCL treated with R-CHOP or CHOP. Results were correlated with patient outcome. HIF-1α expression had no impact on survival for the patients treated with CHOP. In the R-CHOP-treated group, however, HIF-1α expression was significantly correlated with superior OS and EFS (P = 0.048 and 0.040, respectively). Moreover, HIF-1α expression maintained independent prognostic value for OS (RR, 0.41; 95% CI, 0.19-0.92; P = 0.030) and EFS (RR, 0.53; 95% CI, 0.31-0.90; P = 0.020) when it was adjusted by IPI stratification. Therefore, HIF-1α expression benefits from R-CHOP in DLBCL.

Abstract The aim of this study was to evaluate the prognostic importance of rituximab and radiotherapy in patients with primary mediastinal large B-cell lymphoma (PMBCL) receiving doxorubicin-containing chemotherapy. Seventy-nine patients with PMBCL received CHOP chemotherapy with (n = 39) or without rituximab (n = 40), and 60 patients received additional radiotherapy. Patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) had significantly superior survival rates. The 5-year overall survival (OS) and progression-free survival (PFS) rates were 83.7% and 76.7% for R-CHOP, compared with 48.3% (p = 0.011) and 44.2% (p = 0.012) for CHOP, respectively. Similarly, the 5-year OS and PFS rates for early stage patients were 93.8% and 84.6% with R-CHOP, and 52.0% (p = 0.002) and 46.6% (p = 0.003) with CHOP, respectively. Patients treated with chemotherapy and radiotherapy had better survival and local control (LC) rates compared with chemotherapy alone. The 5-year OS, PFS and LC rates for early stage patients were 73.6%, 69.9% and 92.6% for chemotherapy and radiotherapy, and 50.8% (p = 0.076), 36.9% (p = 0.008) and 56.4% (p < 0.001) for chemotherapy alone, respectively. Early stage patients treated with R-CHOP and radiotherapy had 5-year OS, PFS and LC rates of 96.4%, 85.9% and 93.1%. R-CHOP plus consolidation radiotherapy was associated with excellent survival and LC rates.

Despite high initial response rates, a subset of dogs with B-cell lymphoma responds less robustly to CHOP-based chemotherapy and experiences shorter survival. One hundred and four dogs with nodal B-cell lymphoma were treated with a response-based CHOP (RBCHOP) protocol modified based on response to individual drugs during the first chemotherapy cycle. Dogs achieving complete (CR) or partial response (PR) at week 3, following treatment with vincristine and cyclophosphamide, received RBCHOP 1 (n = 72), a protocol sequentially rotating vincristine, cyclophosphamide, and doxorubicin. Dogs without a detectable response at week 3 that subsequently achieved CR or PR following treatment with doxorubicin received RBCHOP 2 (n = 14), in which four doses of doxorubicin were given consecutively followed by vincristine and cyclophosphamide. Dogs that failed to respond at week 3 and then to doxorubicin at week 5 assessment were offered rescue chemotherapy (RBCHOP 3, n = 18). Median progression free survival (PFS) and overall survival time (OST) were similar between RBCHOP 1 (PFS 210 days, OST 354 days) and RBCHOP 2 (PFS 220 days, OST 456 days), but significantly shorter for RBCHOP 3 (PFS 34 days, OST 80.5 days, P < 0.001). No presenting signalment nor hematologic variable differentiated patient cohort, however, dogs in RBCHOP 2 and RBCHOP 3 were more likely to have a lymphocytosis at diagnosis (P = 0.02 and 0.04, respectively). Protocol modification based on response during the first cycle resulted in similar toxicity profiles and outcomes to previously published variants of CHOP, and prognosis remained poor for dogs failing to respond during the first treatment cycle.

Lymphoma, especially non-Hodgkin's lymphoma is extremely rare in pregnancy. A 24-year-old pregnant woman was diagnosed with diffuse large B-cell lymphoma (DLBCL), a subgroup of non-Hodgkin's lymphoma, at 24 weeks' gestation, and was treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy. After 4 cycles of R-CHOP, she delivered a healthy baby via cesarean section at 34 weeks and 5 days' gestation because of preterm contraction-related fetal distress. The patient was administered the remaining 2 cycles of R-CHOP after delivery. Follow-up magnetic resonance imaging and computed tomography showed complete remission. Here, we report a rare case of DLBCL successfully treated with R-CHOP chemotherapy during pregnancy, we also performed a systematic review of literature for similar cases. There were 3 earlier reports of R-CHOP treatment for DLBCL. All cases, including our case, resulted in preterm birth. Together, these findings suggest that R-CHOP chemotherapy for DLBCL in pregnancy may be associated with preterm birth.

Dogs with multicentric T‐cell lymphoma are commonly treated with CHOP chemotherapy protocols that include cyclophosphamide, doxorubicin, vincristine and prednisone. The purpose of this study was to evaluate the use of CHOP chemotherapy for dogs with multicentric T‐cell lymphoma. Identification of prognostic factors in this specific subset of dogs was of secondary interest. Twenty‐three out of 24 dogs responded to CHOP chemotherapy and these dogs remained on the protocol for a median of 146 days. No variable was associated with progression free survival (PFS) including stage, substage, hypercalcemia or radiographic evidence of a cranial mediastinal mass. The median overall survival time (OST) for all dogs was 235 days. Dogs that were thrombocytopenic at presentation experienced a significantly longer OST (323 versus 212 days, P = 0.01).

Cyclophosphamide exhibits the weakest therapeutic effect compared with vincristine and doxorubicin in the CHOP (C, cyclophosphamide; H, doxorubicin; O, vincristine; and P, prednisolone) chemotherapeutic protocol for the treatment of canine lymphoma. Twenty dogs with multicentric lymphoma were treated using the LHOP protocol, which used l-asparaginase in place of cyclophosphamide, and the outcomes were historically compared with those of dogs that received CHOP chemotherapy in the same institution. No significant differences were found in age (p = 0.107), body weight (p = 0.051), sex (p = 0.453), clinical stage V (p = 1), substage b (p = 0.573), T-cell phenotype (p = 0.340), overall response (p = 1), and hypercalcaemia status (p = 1) between the LHOP and CHOP groups. The adverse effects of l-asparaginase were well tolerated and self-limiting. The median PFS (progression-free survival) and median ST (survival time) in the LHOP group were 344 days (range: 28–940 days) and 344 days (range: 70–940 days), respectively. The median PFS and median ST in the CHOP group were 234 days (range: 49–1822 days) and 314 days (range: 50–1822 days), respectively. The dogs that received LHOP chemotherapy had a significantly longer PFS than the dogs that received CHOP chemotherapy (p = 0.001). No significant difference was observed in ST between the LHOP and CHOP groups (p = 0.131). Our study findings thus indicate that the LHOP protocol can be used as a first-line chemotherapeutic protocol in canine multicentric lymphoma.
