RESUMO

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is the commonest subtype of lymphoma, standard CHOP was the treatment of choice, 42% of patients received rituximab, and 29% of patients were lost to follow-up during therapy, were reported in a study that collected retrospective data at 13 public and private hospitals for patients diagnosed with lymphoma between January 2005 and December 2009. The OncoCollect Registry was set up in 2017 to address the challenges in the collection of retrospective data through chart review, recording access to anthracycline and rituximab-based treatment, and to study outcomes and any improvement in the patient follow-up. METHODOLOGY: The OncoCollect Lymphoma group registry was set up at a national level with 9 participating centers. Lymphoma patients registered at these centers between 2011 and 2017 were included. The clinical features, prognostic stratification, associated comorbidities, response to first-line treatment, and 3-year outcomes of adult patients with DLBCL were analyzed. RESULTS: Of the 5,886 lymphoma patients registered in the OncoCollect registry, 2,581 (44%) had DLBCL. A total of 1,961 were evaluable for frontline therapy. The median age at presentation was 57 years. Gender ratio was 1.6:1. At presentation, 43% were early stage, 70% had low and low intermediate IPI, 53% had extranodal disease, and 30.9% had one or more comorbidities (data available for 1,136 patients). The commonest extra nodal site was gastro-intestinal (23.98%) followed by head and neck (19.24%). The overall response rate was 79.29%. Complete remission was seen in 61.75%, partial response in 17.5%, stable disease in 4.3%, and progression in 7.9%. Patients who received anthracycline-based therapy (86.7%) and rituximab-based therapy (83.7%) had a 3-year event-free survival (EFS) of 69.67% and 68.48%, respectively. With a median follow-up of 33 months, the 3-year overall Survival (OS) and EFS were 75.37% and 66.58%, respectively. CONCLUSIONS: DLBCL remains the commonest (44%) lymphoma subtype and is curable with standard anthracycline- and rituximab-based therapies. The availability of rituximab has increased the proportion of patients receiving standard chemoimmunotherapy.

RESUMO

BACKGROUND: Hodgkin's lymphoma (HL) is one of the most curable malignancies with a 5-year survival of over 80%. Most published literature from low-middle income countries comes from single institute experience. METHODOLOGY: The OncoCollect Lymphoma group registry was set up in 2017 and has 9 major participating sites across India. Data of newly diagnosed classical HL (CHL) patients, treated between 2011 and 2017, were collected using OncoCollect software. The clinical features, subtypes, prognostic stratification, treatment patterns, response to first-line treatment, and 5-year outcomes were analyzed. All statistical analysis was done using Microsoft R Open statistical software linked to OncoCollect software. RESULTS: There were 939 newly diagnosed CHL patients with a median age of 38 (range, 18-99) years at presentation. The male-to-female ratio was 2.07:1. Histological subtypes included mixed cellularity, CHL (MC, CHL), nodular sclerosis, CHL (NS, CHL), lymphocyte-rich, CHL (LR, CHL), and lymphocyte-depleted, CHL (LD, CHL), in 60.60%, 26.94%, 9.80%, and 2.66%, respectively. At presentation, 50.43% had B symptoms and 53.35% had advanced disease. 29.71% of advanced-stage patients had high Hodgkin IPI score. 79% and 21% of patients received 1st-line treatment with chemotherapy alone or combined modality treatment with chemotherapy and radiotherapy. The most common first-line chemotherapy was ABVD-based regimen (94.68%). The overall response rate was 93.48%. Complete response rates among early-stage favorable and unfavorable risk groups were 92.73% and 86.79%, and those among advanced-stage low- and high-risk groups were 76.64% and 69.78%, respectively. The median relapse-free follow-up duration was 51 months (IQR 22-69). A significant difference was found in 5-year EFS between the early- and advanced-stage disease 83.53% and 73.55% (p = 0.00087), respectively. Similarly, significant difference was found in EFS among early-stage patients treated with a combination of 4-cycle chemotherapy and radiotherapy vs. chemotherapy alone 88.57% and 66.33% (p = 0.0042), respectively. CONCLUSIONS: In this large cohort from India, survival of patients with HL was comparable to the developed world. With a median follow-up of 51 months, the 5-year EFS and OS of all patients were 78.24% and 83.63%, respectively.

RESUMO

INTRODUCTION: The aim of the study is to investigate the activity and safety of oral talactoferrin (TLF) plus carboplatin and paclitaxel (C/P) in patients with previously untreated stage IIIB/IV non-small cell lung cancer. METHODS: Patients (n = 110) were randomly assigned to receive C/P plus either TLF (C/P/T) or placebo (C/P/P). The primary objective of this exploratory study was assessment of confirmed response rate (RR) in the prospectively defined evaluable population with a one-tailed p = 0.05. Secondary objectives included assessment of progression-free survival (PFS), duration of response, overall survival (OS), and safety. RESULTS: The trial met the primary end point of improvement in confirmed RR in the prospectively defined evaluable population. Compared with the C/P/P group, RR increased in the C/P/T group by 18% (29-47%; p = 0.05) and 15% (27-42%; p = 0.08) in the evaluable and intent-to-treat populations, respectively. Compared with the C/P/P group, the C/P/T group had a longer median PFS (4.2 versus 7.0 months), OS (8.5 versus 10.4 months), and duration of response (5.5 versus 7.6 months), although the differences were not statistically significant. Adverse events (AEs) were consistent with C/P therapy. There were fewer total AEs (472 versus 569; two-tailed p = 0.003) and grade 3/4 AEs (78 versus 105; p = 0.05) in the C/P/T group compared with the C/P/P group. CONCLUSION: TLF, in combination with C/P, demonstrated an apparent improvement in RR, PFS, and OS in patients with previously untreated stage IIIB/IV non-small cell lung cancer and appears to enhance activity without significant additional toxicity. These results need to be confirmed in a phase III trial.
