Abstract Context Treatment-related toxicities in DLBCL (diffuse large B cell lymphoma) patients are higher in the initial phase of treatment (first cycle effect). Implementation of pre-phase treatment before definitive chemotherapy had been shown to alleviate some of these side-effects in a non-randomized study conducted earlier in our institute (Lakshmaiah et. al., Eur J Haematol 100:644-8, 2018). Aims This study was aimed at validating the role of pre-phase treatment in newly diagnosed DLBCL patients. Settings and design All newly diagnosed patients with DLBCL above the age of 18 years were evaluated for eligibility and prospectively enrolled. A single-arm prospective study was conducted at the Department of Medical Oncology, in our institute from July 2015 to December 2019. Methods and material Patients received vincristine and prednisolone as pre-phase treatment for 7 days after which definitive chemotherapy was instituted on day 1. They were followed up for 30 days post-first cycle chemotherapy. Statistical analysis used Paired Student’s t tests and Wilcoxon signed-ranks test were used for comparison of various clinical variables as appropriate. P value of less than 0.05 was considered significant. Results Among the 180 patients who were included in study, performance status improvement was noted in significant number of patients (p < 0.001). 38.4% achieved an ECOG (Eastern Cooperative Oncology Group) performance status of 0 post-pre-phase therapy. Febrile neutropenia was observed in 12.8% in the present cohort as compared to the historical non-pre-phase cohort (34%). Conclusions Pre-phase therapy significantly improves the performance status and diminishes neutropenia rates in DLBCL patients.

Multiple myeloma constitutes a wide spectrum of diseases ranging from slow-growing monoclonal gammopathy of undetermined significance to rapidly progressing plasma cell leukemia. It is a very rarely diagnosed hematological malignancy in those less than 30 years. A 25-year-old male presented with complaints of fatigue, and low-grade fever. On investigations, he was found to have bicytopeina and features of tumor lysis syndrome. This was initially thought to be consistent with a diagnosis of acute leukemia. Upon further analysis with bone marrow biopsy, serum protein electrophoresis, and immunofixation, the rare diagnosis of IgG myeloma with plasmablastic morphology was confirmed. However, it rapidly progressed and peripheral smear started showing clusters of plasma cells. Despite aggressive treatment, the patient succumbed to aggressive plasma cell leukemia with an underlying plasmablastic morphology. This case highlights the possibility of myeloma as one of the differentials in young patients especially the rare plasmablastic variant that can get misdiagnosed as acute leukemia. This aggressive morphology may also show rapid progression to plasma cell leukemia and has an adverse prognosis.

Background Adult Philadelphia-positive (Ph + ) acute lymphoblastic leukemia (ALL) is a distinct entity with poor prognosis. Treatment with tyrosine kinase inhibitors improved responses but still with poor outcomes. We evaluated treatment outcomes in these patients treated in limited-resource settings in the absence of availability of allogeneic stem cell transplantation (ASCT). Materials and Methods We studied case record files of the adult patients diagnosed with Ph+ ALL. Results A total of 18 patients were evaluated retrospectively. The median age of presentation was 28 years. Male-to-female ratio was 1:1. Patients presented with fever and fatigue. Six patients (33.33%) presented with cervical lymphadenopathy. Clinical splenomegaly was present in 16 (88.88%) patients on palpation, whereas on ultrasonographic evaluation, all 18 patients had splenomegaly. The median size of the spleen was 15 cm. Hepatomegaly was seen in 5 (27%) patients. All 18 patients had anemia at the time of presentation. Leukocytosis was seen in 17 (94.44%) patients, whereas 1 (5.56%) patient presented with low total leukocyte count. The median platelet count at the time of presentation was 30,000/mm.3 On peripheral smear, median number of blast cells was 55%, and on bone marrow aspiration samples, median blast percentage seen was 70%. Conventional cytogenetics was done in all the patients on bone marrow aspiration samples. Ten patients (55.55%) had t(9;22) – Ph chromosome. One patient (5.56%) on cytogenetics showed double Ph chromosome. The median value of breakpoint cluster region-ABL1 transcript in IS% was 13%. Seventeen (94.44%) received ALL protocol (BFM95) along with tyrosine kinase inhibitor (imatinib). One (5.56%) patient refused aggressive cytotoxic chemotherapy. No patient underwent ASCT. The median duration of follow-up was 7.5 months, ranging from 3 to 16 months. Median overall survival (OS) was 7.5 months and 2-year OS was 33.33%. Conclusion Poor prognosis of this disease, especially in the absence of ASCT, remains a major challenge in the treatment.

Soft tissue sarcomas (STS) are a diverse group of rare solid tumors of mesenchymal cell origin with distinct clinical and pathological features. They account for less than 1% of all adult malignancies and 15% of pediatric neoplasms. They include over hundreds of different histological subtypes. Many of these subtypes can occur at any age and are not confined to a specific site. Each subtype displays variable clinical behavior. Low incidence, variable presentation, behavior, and long-term outcomes further make it challenging to treat. There are multiple ongoing trials that focus on the anatomic site and histologic subtype to tailor the treatment. Further rarity of each histotype is a major barrier to recruit patients to randomized controlled trials. A multidisciplinary approach is mandatory in all cases of soft tissue sarcomas.The purpose of this review is to thoroughly understand the existing literature on history, incidence, epidemiology, etiology, histology, pathogenesis, diagnostic modalities, prognosis, management, and post treatment surveillance of STS. Uterine sarcomas, gastrointestinal stromal tumors (GIST), and pediatric sarcomas are not included here. It briefly highlights various molecular aberrations, changes in staging as per the American Joint Committee on Cancer (AJCC) 8, drugs that are used off-label in specific subtypes of sarcoma along with the recent advances. The classification of STS is undergoing continuous evolution. A wide variety of subtypes can only be diagnosed accurately with sophisticated molecular diagnostic tests and with the involvement of expert geneticists and pathologists to interpret it.There is no clarity on tailoring the treatment of STS to date. There is always a question on how best we can incorporate chemotherapy and radiotherapy along with surgery as a part of multimodality treatment. The heterogeneity of STS has hindered the development of robust, evidence-based treatment strategies, and our therapeutic approach is neither histology-specific nor widely standardized. Increased knowledge about sarcoma biology could help to discover new and more effective treatment strategies and help overcome the therapeutic challenge imposed by this deadly disease. Continued collaboration among various sarcoma centers globally will be of prime importance to optimize STS management. This will allow studies to be both sufficiently large and reasonably focused to generate evidence that is clinically meaningful in specific STS patient populations.
