Central nervous system involvement in multiple myeloma: Experience from a tertiary cancer center and review of literature.

BACKGROUND: Multiple myeloma (MM) results from clonal expansion of immunoglobulin secreting, heavy chain class-switched, terminally differentiated B-lymphocytes (plasma cells), resulting in radiologic or biochemical evidence of end-organ damage. Though neurological manifestations (peripheral neuropathies, spinal radiculopathies, cranial nerve palsies, and metabolic encephalopathies) can occur during the disease course, direct central nervous system (CNS) infiltration by malignant plasma cells (CNS-MM) is very rare (~1%) and has a dismal prognosis (survival of <6 months). METHODOLOGY: Clinico-laboratory profile and outcome of CNS-MM patients diagnosed and treated at a tertiary cancer care hospital were retrospectively analyzed. RESULTS: On scrutinizing 500 consecutive myeloma case records, 4 patients with CNS-MM were identified. All these patients were diagnosed during myeloma relapse, and all had deceased within 1 week and 12 months of developing CNS infiltration. Our experience with CNS-MM patients is similar to the experiences documented across major world literature. CONCLUSION: Our manuscript reinforces that CNS-MM should be considered in any myeloma patient presenting with unexplainable CNS manifestations. As there are no prospective studies to recommend optimal treatment strategies, CNS-MM still remains a dismal complication of myeloma.

Outcomes with chemotherapy in carcinoma penis: Experience from a tertiary cancer center.

Background: Carcinoma penis is more common in India compared to the West. The role of chemotherapy in carcinoma penis is ambiguous. We analyzed the profile and outcomes of patients with carcinoma penis treated with chemotherapy. Methods: We analyzed the details of all patients with carcinoma penis treated at our institute between 2012 and 2015. We collected particulars regarding demography, clinical presentation, treatment details, toxicities, and outcomes of these patients. Event-free and overall (OS) survival were calculated from the time of diagnosis until documentation of disease relapse/progression or death for the patients with advanced carcinoma penis who were eligible for chemotherapy. Results: There were 171 patients with carcinoma penis treated at our institute during the study period including 54 (31.6%) patients with stage I, 49 (28.7%) patients with stage II, 24 (14.0%) patients with stage III, 25 (14.6%) patients with stage IV, and 19 (11.1%) patients with recurrent disease at presentation. The present study included 68 patients with advanced carcinoma penis (stages III and IV) who were eligible for chemotherapy, with a median age of 55 years (range: 27-79 years). Sixteen patients received paclitaxel and carboplatin (PC) and 26 patients cisplatin and 5-FluoroUracil (CF). Neoadjuvant chemotherapy (NACT) was given to four patients with stage III and nine patients with stage IV disease. Of the 13 patients given NACT, we observed a partial response in five (38.5%), stable disease in two (15.4%), and progressive disease in five (38.5%) evaluable patients. Six (46%) patients underwent surgery after NACT. Only 28/54 (52%) patients received adjuvant chemotherapy. After a median follow-up of 17.2 months, the 2-year OS rates were 95.8, 89, 62.7, 51.9, and 28.6% for stages I, II, III, IV, and recurrent disease, respectively. The 2-year OS of patients who were given chemotherapy versus those who were not given chemotherapy were 52.7 and 63.2%, respectively (P = 0.762). Conclusions: We report the real-world outcomes of two chemotherapeutic regimens used in consecutive patients with advanced carcinoma penis. Both PC and CF seemed effective and safe. However, approximately half of patients with advanced carcinoma penis do not receive the planned/indicated chemotherapy. We need further prospective trials regarding the sequencing, protocols and indications of chemotherapy in this malignancy.

Relevance of flow cytometric categorization and end-of-induction measurable residual disease assessment in pediatric and adult T-lymphoblastic leukemia patients.

Background: T-lymphoblastic leukemia (T-ALL) patients expressing myeloid/stem cell antigens are classified as early T-cell precursor lymphoblastic leukemia (ETP-ALL) or near-ETP-ALL. Methods: Clinico-laboratory profiles, flow cytometric end-of-induction measurable residual disease (EOI-MRD), and survival of treatment naïve T-ALL patients were analyzed according to their immunophenotypic subtypes. Results: Among 81 consecutive T-ALL patients diagnosed, 21% (N=17) were ETP-ALL and 19% (N=15) were near-ETP-ALL. EOI-MRD was detectable in 39% of the 59 samples tested (31.6% of pediatric samples and 52.4% of adult samples). The frequency of EOI-MRD positivity was significantly higher among ETP-ALL (75%, P=0.001) and near-ETP-ALL (71%, P=0.009) patients compared to that in conventional-T-ALL (con-T-ALL) patients (22.5%). CD8 (P=0.046) and CD38 (P=0.046) expressions were significantly upregulated in the EOI blasts of con-T-ALL and ETP-ALL samples, respectively. The 2-year rates of overall (OS), relapse-free (RFS), and event-free survival (EFS) among the T-ALL patients (pediatric vs. adult) was 79.5% vs. 39.8% (P<0.001), 84.3% vs. 60.4% (P=0.026), and 80.3% vs. 38% (P<0.001), respectively. Univariate analysis revealed that 2-year EFS and RFS of pediatric T-ALL patients was independent of T-ALL subtype and was influenced only by EOI-MRD status. However, 2-year OS, RFS, and EFS among adult T-ALL patients were EOI-MRD independent and influenced only by the near-ETP-ALL phenotype. Conclusion: Two-year survival among pediatric and adult T-ALL patients is attributed to EOI-MRD status and near-ETP-ALL phenotype, respectively.

Forecasting factors and outcomes in hawkish inflammatory breast carcinoma - A single center data exploration.

INTRODUCTION: Inflammatory breast carcinoma (IBC) is an aggressive clinical syndrome of invasive breast carcinoma. There is paucity of data regarding the outcomes in IBC. OBJECTIVES: Analyses of OS and Event-free survival (EFS) in nonmetastatic and metastatic IBC and to find prognostic factors influencing them. METHODOLOGY: In this single center, retrospective study the data of patients fulfilling the clinical criteria of IBC were retrieved from 2016 to 2021. The impact of prognostic factors on OS and EFS were analysed by log rank test (univariate analysis). The OS and EFS were depicted as Kaplan Meier survival curves. RESULTS: There were 22 patients with IBC. Median follow-up was 17 months. The median OS was significantly better in non-metastatic(M0) compared to metastatic IBC (25 months vs 6 months) with 3year OS rate of 50% vs 0% respectively. The post-menopausal status, grade 2 histology and trimodality treatment showed better outcome while N3 stage at diagnosis had worse outcome in M0 group. The lesser HR expression, lesser pCR rates, higher N3 proportion, liver metastasis and multiple metastatic site involvement contributed to the worse outcome observed in this study. CONCLUSION: The aggressive clinicopathological features of IBC in the present study resulted in less favourable outcome compared to literature review. Improved outcome with trimodality highlights the emergent need for additional targeted therapy to improve pCR and operability.

Therapeutic Outcomes in High-Grade B-Cell Lymphoma, NOS: Retrospective Analysis.

The nomenclature high-grade non-Hodgkin's lymphoma was repurposed in the World Health Organization (WHO) 2016 update as high-grade B cell lymphoma (HGBL). However, among the HGBL entities HGBL, not otherwise specified (NOS) remains a poorly described entity with a lack of literature regarding its treatment and prognosis. The baseline characteristics, treatment, and outcome of HGBL, NOS cases were analyzed. Thirty HGBL, NOS patients were diagnosed between January 2017 and December 2019. Their median age was 49.3 years, and 30% had advanced IPI. The majority received R-CHOP chemotherapy, while five patients received dose-adjusted R-EPOCH. At a median follow-up of 15 months, nine patients had disease progression or relapse. EFS and OS were 22 months (12.1-31.9 months) and 37 months (29.4-44.0 months) respectively. Only NCCN-IPI ≤ 2 showed significant influence on the outcome. The results were similar to the outcomes previously reported. This study highlights the importance of NCCN-IPI in ascertaining the prognosis of HGBL, NOS. The literature review suggests that more intensive chemotherapy is ideal for HGBL, NOS. However, prospective trials are needed to prove whether the treatment of HGBL, NOS can be tailored based on NCCN-IPI.

The continuing conundrum in oligometastatic breast carcinoma: A real-world data.

The optimal management in Oligometastatic (OM) breast carcinoma is not defined. OBJECTIVES: To identify the prognostic factors influencing OM and the effect of Locoregional treatment (LRT) on survival in OM. METHODOLOGY: Patients with ≤5 metastases and each with ≤ 5 cm size were defined as OM. Data of OM were extracted from the Institute Registry between 2012 and 2018. The impact of prognostic factors on survival was analysed by univariate and multivariate Cox regression. The Kaplan Meier survival curves were used to plot PFS and OS. RESULTS: There were 170 patients with OM. The median follow-up was 61 months. Median OS was 43.3 months. The median OS was 74 months in OMD vs 22.7 months in Oligorecurrent disease (ORD) with 5year OS rate of 55.3% vs 16.5% respectively. In the multivariate analyses of OMD both Ki67 ≤ 50% and hormone therapy (HT) showed significant favourable survival outcome. While premenopausal status and HT showed significant survival benefits in ORD. The worse survival outcome in ORD could be because of their aggressive biology and deficit in LRT compared to literature review. The prognostic factors were swayed by the uneven distribution of HR status, grade and Ki67. CONCLUSION: The survival of OM was influenced by OMD, Ki67 ≤ 50%, premenopausal status and HT. The lesser survival rates of OM in the long term suggest the need for curative LRT to metastatic sites and primary tumor. The potential role of HT and targeted therapy with or without LRT need to be assessed in future randomised trials.

Precursor B-lineage acute lymphoblastic leukemia patients with aberrant natural killer cell and T cell - lineage antigen expression: experience from a tertiary cancer care center

Abstract Introduction Flow cytometric immunophenotyping (FCI) plays a major role in diagnosing hematologic malignancies. In patients diagnosed with precursor B-lineage acute lymphoblastic leukemia (B-ALL), expression of certain non-lineage/cross lineage antigens is of prognostic and cytogenetic relevance. There is a paucity of studies that have comprehensively analyzed the clinical and laboratory profiles of B-ALL patients showing aberrant T/natural killer (NK) cell antigen expression. Materials and methods This is a prospective study where 152 consecutive B-ALL patients were analyzed for aberrant expression of T/NK cell antigens (CD1a, CD5, CD4, CD7, CD8 and CD56) by FCI. The clinical and laboratory profile of these T/NK-cell antigen-expressing B-ALL patients was statistically analyzed against conventional B-ALL patients. Results In our B-ALL cohort, CD5, CD7 and CD56 expression were observed in one, six and nine patients, respectively. CD56-expressing B-ALL patients were predominantly children (89%) and presented as standard clinical risk (p = 0.010) disease with frequent ETV6-RUNX1 fusion (p = 0.021) positivity. On the contrary, CD7-expressing B-ALL patients were adolescent-young adult/adult-age skewed (83%) and had an adverse cytogenetic profile (p = 0.001), especially for the frequent presence of BCR-ABL1 fusion (p = 0.004) and KMT2A rearrangement (p = 0.045). CD7-expressing B-ALL patients had inferior event-free survival (p = 0.040) than their CD56-expressing counterparts, but there was no significant difference in the overall survival (p = 0.317). Conclusion In comparison to conventional B-ALL patients, there are significant differences in the age, cytogenetic profile and event-free survival of T/NK-cell antigen-expressing B-ALL patients.

Immunophenotypic expression and immunomodulation in minimal residual disease analysis of pediatric B acute lymphoblastic leukemia by high sensitive flow cytometry.

The major challenge in minimal residual disease (MRD) detection is the antigen modulation in post treated samples restraining the use of diagnostic immunophenotypic (IP) signature of leukemic blasts for MRD detection. The IP expression of 10 antigens in 167 children diagnosed as B-acute lymphoblastic leukemia (B-ALL) in comparison to hematogones and the extent of immunomodulation in 60 post treated MRD positive cases were studied. Upregulation was the predictable shift noted in antigens like CD73, CD86, CD19, CD20 and CD45 which was statistically significant for all except CD45. Downregulation was the predictable shift noted in antigens like CD10, CD38, CD58 and CD34 and was statistically significant in all. CD123 showed no significant trend. This immunomodulation in B-ALL results in aberrant expression of antigens during follow-up compared to the diagnostic phenotypic pattern. Hence it is necessary to be aware of the immunomodulations of antigens used in primary diagnosis to avoid being misled during MRD analysis.

Autologous Stem Cell Transplantation in Testicular Germ Cell Tumor-Preliminary Experience from a Single Center.

Background Germ cell tumor (GCT) of the testis is one of the highly curable solid organ malignancies. Those who experience relapse after platinum-based chemotherapy can be salvaged with systemic therapy followed by high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). Complete remission can be obtained in approximately 50 to 60% of patients treated with HDCT. Our experience reports the efficacy and safety of HDCT followed by ASCT in relapsed GCT. Methods Analysis of patient records (2012-2019) showed that three patients had received HDCT and ASCT. Results All the three patients were treated with BEP (bleomycin, etoposide, and cisplatin) as first-line therapy. HDCT was done in Case 1 after third-line salvage and in other two patients after second-line salvage chemotherapies. High-dose carboplatin and etoposide were used as conditioning regimen. Granulocyte colony-stimulating factor was used for the mobilization of stem cells. After ASCT, complete remission was documented in all the patients. All were alive and disease-free till the last follow-up. Grade ¾ toxicities including myelosuppression, diarrhea, and mucositis were observed in all three patients. Conclusion This is the first report from India on HDCT with ASCT in GCT. HDCT/ASCT seems to be feasible, safe, and effective in relapsed testicular GCTs.

Blast size-specific flowcytometric ploidy assessment using FxCycleTM Violet dye and its correlation with conventional cytogenetic ploidy in pediatric precursor B-lineage acute lymphoblastic leukemia patients.

INTRODUCTION: Numerical chromosomal abnormalities (aneuploidies), present in approximately 30%-50% of pediatric precursor B-lineage acute lymphoblastic leukemia (B-ALL) patients, are commonly identified through a laborious conventional cytogenetic (CG) technique. Flow cytometry (FCM) can identify both physical and fluorescent properties of cells together, and by using fluorescent nucleic-acid-binding dyes, FCM can identify variations in total nucleic-acid content of cells. FxCycleTM Violet dye (FxCV) is a selective DNA-binding dye which permits simultaneous multiparametric immunophenotyping and cell-cycle/ploidy assessment in a single assay. To date, only two studies have demonstrated the feasibility of FxCV-aided FCM-ploidy analysis in B-ALL patients and only one of these studies have compared their results with CG-ploidy. METHODOLOGY: Blast size-specific FCM-ploidy was prospectively analyzed using FxCV-dye in 109 pediatric B-ALL patients, and the results were compared with concurrent CG-ploidy status. RESULTS: FCM-ploidy categorization was feasible in 98% of samples tested and the results were 82% concordant with CG-ploidy status. We observed significant correlation between DNA content and blast size (r = .823, P < .001) and could demonstrate size differences between diploid vs low-hyperdiploid (P = .025), diploid vs high-hyperdiploid (P < .001) and low- vs high-hyperdiploid blasts (P = .007). CONCLUSION: FCM-ploidy assessment using FxCV dye is a reliable assay and the results closely concur with CG-based ploidy stratification and risk assessment. Using blast size-assisted DNA content analysis, the results of FCM-ploidy analysis can be further fine-tuned.

Intravesical Bacillus Calmette-Guerin (BCG) Therapy for Non-muscle Invasive Bladder Cancers: Long-term Results of a Modified Schedule.

Intravesical BCG therapy is an integral part of management of non-muscle invasive bladder cancers. Our aim is to analyze the non-muscle invasive bladder cancer patients treated at our center with a modified schedule intravesical BCG therapy. Data from patients treated at our center from 2009 to 2017 was collected from patient records and analyzed. A 6-weekly 120-mg induction course followed by 6 monthly 120 mg has been used at our institute for NMIBC. Clinicopathological and treatment variables were collected. A total of 119 patients were treated at our center with a median follow-up period of 4.18 years with the above schedule. Nearly 96% patients were able to complete induction therapy and 79% completed the maintenance therapy. The 5-year recurrence-free survival was 83%. The recurrence and progression rates were 16.8% and 4.2% respectively. About 60% of the patients suffered from side effects of BCG with 11% having class 3 or 4 toxicity. Our regimen of monthly maintenance intravesical BCG for 6 months shows good control rates with high compliance, similar to those of other contemporary series, although with higher incidence of high-grade toxicity.

Recurrent cervical cancer treated with palliative chemotherapy: real-world outcome.

INTRODUCTION: Cervical cancer is the third most common cancer in India. There is limited data on the treatment of relapsed cervical cancer from India; therefore, we report the outcomes of patients with recurrent cervical cancer who were treated with palliative chemotherapy (CT). MATERIALS AND METHODS: This was a retrospective study of patients with recurrent cervical cancer who received palliative CT from January 2012 to December 2016. The demographic details, clinical profile and survival outcomes were collected. Patients were treated with carboplatin or paclitaxel and carboplatin. Local radiation was given for symptomatic patients. Patients were assessed for responses clinically and/or radiologically after three and six cycles of CT. Progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. RESULTS: Forty-six patients with recurrent cervical cancer were included in this analysis, with a median follow-up of 9.4 months. The median age was 49.5 (25-65) years and the median disease-free interval was 31.3 (2-196) months. Biopsy confirmation of relapse was established in 63%. The median number of CT cycles was six. Twenty-four (52.2%) patients completed six cycles of CT. The overall response rate was 56.5%. Patients with a complete or a partial response were more likely to have PFS > 6 months (p < 0.0001). Median PFS and OS were, respectively, 8.4 (95% CI 6.1-10.7) months and 10.3 (95% CI 6.8-13.8) months. The completion of all cycles of CT and the site of metastasis (nodal vs. visceral or combined) were found to be associated with OS. CONCLUSION: Palliative CT with paclitaxel carboplatin is a safe and effective option in Indian patients with recurrent cervical cancer, with more than half of the patients completing the prescribed CT. Further prospective trials may be required to place this treatment in the right context, in this era of immunotherapy and targeted therapy. However, knowing the outcomes in our population and prognostic factors will help in better prognostication of patients, thereby channelling our limited resources where necessary.

Plasmablastic lymphoma - single centre experience with infusional EPOCH chemotherapy.

BACKGROUND: Plasmablastic lymphoma (PBL) is a rare type of aggressive large B - cell non-Hodgkin Lymphoma (NHL) which was initially described in HIV positive individuals and later was also described in immune-competent individuals. It was included as a distinct entity in the WHO lymphoma classification in 2008. METHODS: The clinical features, HIV status, treatment details, and outcomes of patients diagnosed with plasmablastic lymphoma from January 2012 to December 2018 were retrospectively collected from the patient records and analyzed. The survival analysis was done by Kaplan Meier analysis and the comparison was done by the Log Rank test. RESULTS: The median age of 25 patients, included in the study was 41 years (Range 13-71 years). Males constituted 76 %. HIV positivity was 72 %. Stage IV disease was present in 76 %. Extranodal involvement was seen in 96 %. Out of 25 patients, seven did not receive any treatment and three received metronomic oral chemotherapy due to poor performance status at presentation. Fifteen patients received chemotherapy on a curative intent. Infusional EPOCH chemotherapy was given in 13 patients. CHOP and CHOEP chemotherapy was given in one patient each. The median number of cycles was 6 (Range: 3-8). The overall response rate of patients treated on a curative intent was 80 % (Complete response and partial response in 8 and 4 respectively). Three patients underwent high dose chemotherapy with autologous stem cell rescue at first remission. The median event-free survival (EFS) and median overall survival (OS) of the whole study population was 5.9 and 12.4 months respectively, with a median follow of 26.9 months. The median EFS was 13.8 months and the median OS was not reached in the curative-intent group. The factors adversely influencing the EFS and OS were Age > 40 years, high IPI, and non-curative intent of treatment. CONCLUSION: Plasmablastic lymphoma commonly presents as stage 4 disease with extranodal involvement and is more common in immune-deficient individuals. Infusional EPOCH chemotherapy is a promising option that induces long term remission.

Flow Cytometry Based MRD and Its Impact on Survival Outcome in Children and Young Adults with ALL: A Prospective Study from a Tertiary Cancer Centre in Southern India.

Presence of minimal residual disease (MRD) following induction chemotherapy is a well-recognized risk factor to predict relapse in acute lymphoblastic leukemia (ALL). There is paucity of data on MRD and outcome in ALL from India. We share our experience in establishing a flow cytometry-based MRD assay for ALL with emphasis on determination of the number of patients who had MRD on day 35 of induction therapy and its correlation with outcome and other prognostic factors. We prospectively studied MRD in patients with ALL less than 25 years who achieved morphological complete remission with induction therapy. The initial series consisted of 104 patients with ALL. Ninety-two patients had bone marrow samples collected on day 35 of remission induction chemotherapy that was adequate for MRD. Strategy of monitoring MRD was based on flow cytometry using six color staining according the leukemia associated immunophenotype found at diagnosis. Data analysis was done using Fisher exact test. The median age was 8.5 years (range 0.9-22 years). Thirty-seven out of ninety-two patients (40.2%) had MRD at end of induction. MRD on day 35 was between 0.01 and 0.1% in 18.9% of patients, between 0.1 and 1% in 59.5% and more than 1% in 21.6% patients. Among the patients who had MRD, 16.7% had favourable cytogenetics, 60% had intermediate and 13.3% had high-risk cytogenetics. The presence or absence of residual leukemia by flow cytometry at day 35 was not significantly related to age (p = 1.0), male gender (p = 0.08) hyperleukocytosis (p = 0.25) or day 8 blast clearance (p = 0.21). However, T cell phenotype (p < 0.001) was significantly associated with MRD. The 5-year event free survival (EFS) for patients who had MRD versus those who did not was 69% and 61.1% respectively (p = 0.41). The 5-year overall survival (OS) for patients who had MRD versus those who did not was 72.5% and 61.1% respectively (p = 0.33). Flow cytometric techniques can be applied to monitor MRD in patients of ALL undergoing induction therapy. Our results suggest MRD correlates with certain known prognostic factors. Though the EFS and OS was lower in MRD positive patients, the results were not statistically significant probably because of the small sample size.

A modified olanzapine-based anti-emetic regimen for the control of nausea and vomiting in patients receiving weekly cisplatin.

Background There is limited data on specific antiemetic protocols for control of chemotherapy-induced nausea/vomiting (CINV) caused by weekly cisplatin regimens. Olanzapine is an active agent against CINV and may offer better control of nausea compared to aprepitant/fosaprepitant-based regimens. The usual antiemetic dose of olanzapine (10 mg for four days) causes problems with drowsiness. A lower dose may be as effective with lesser side effects in patients receiving weekly cisplatin. Objective To assess the control of nausea, vomiting, and occurrence of side effects with a modified olanzapine-based antiemetic regimen among patients with carcinoma of the cervix receiving concurrent cisplatin with pelvic radiotherapy. Setting Tertiary cancer hospital in Southern India. Methods We used a modified regimen "mini-OPD", oral olanzapine (5 mg) days 1 and 2, intravenous palonosetron (0.25 mg) and dexamethasone (12 mg) on day 1 of cisplatin administration in patients with carcinoma of the cervix receiving concurrent chemoradiotherapy with weekly cisplatin (40 mg/m2/week). At our centre, these patients remained inpatients throughout chemoradiotherapy. CINV-related outcomes were captured in the patients' records by the treating physician in the subsequent week (up to 6 times per patient depending on the number of cycles). We audited these records to calculate the complete response (CR defined as no emetic episodes and no use of rescue medication) rate. Main outcome measure Grades of nausea, vomiting, and drowsiness as per CTCAE v4.0. Results Data of 65 patients (median age: 48 years) who received mini-OPD regimen (median doses of cisplatin/patient: 4) was available. The CR rate was 55%. Considering all cycles together (217 weekly assessment points), "no nausea" target was attained in 125 (58%) assessments and "no vomiting" in 168 (77%). There were no significant side effects. Conclusions The mini-OPD regimen is an inexpensive, non-toxic and effective regimen for the prevention of CINV in patients receiving weekly cisplatin concurrent with pelvic radiotherapy.

Gemcitabine, vinorelbine and dexamethasone: A safe and effective regimen for treatment of relapsed/refractory hodgkin's lymphoma.

BACKGROUND: Salvage regimens in relapsed/refractory Hodgkin's lymphoma (HL) differ in their efficacy and toxicity profiles. Gemcitabine (G), vinorelbine (V) and liposomal doxorubicin (GVDoxil) is one regimen with high response rates but has high toxicity and cost. We devised a regimen of GVDex by substituting the more expensive liposomal doxorubicin with the cheaper high-dose dexamethasone (Dex). PATIENTS AND METHODS: We analyzed the data of 48 adult and paediatric patients of relapsed/refractory HL who received GVDex as salvage therapy. GVDex was delivered as outpatient once in 3 weeks (Q3 weekly) (G 1000 mg/m2 IV over 30 min on D1, 8; V 25 mg/m2 IV fast infusion on D1, 8; Dex40 mg PO D1-4) for 2-3 cycles. We present the overall response rate, toxicity, progression-free (PFS) and overall survival (OS) from the time of start of GVDex. RESULTS: Forty-eight patients [median age: 24 years (5-63)] received GVDex [(median cycles:3(1-6)] in this period. Median time from diagnosis to the first relapse was 18.9 (2-119) months. Overall response rate [ORR = complete (CR)+partial (PR)] was 63%. Eleven (23%) patients developed febrile neutropenia. After a median follow-up of 20 months, the Kaplan-Meier estimates of patients alive and progression-free at 24 months were 60% and 49%, respectively. CONCLUSIONS: The response rates with GVDex were comparable to those reported with GVDoxil when used as a first-line salvage regimen in relapsed/refractory HL. It was an effective regimen even in patients who failed 2 lines of therapy for HL.

CD19 negative and dim precursor B-lineage acute lymphoblastic leukemias: real-world challenges in a targeted-immunotherapy era.

Flow cytometric diagnosis and minimal residual disease (MRD) assessment of precursor B-lineage acute lymphoblastic leukemia (B-ALL) are heavily dependent on CD19 based gating strategies. However, this approach is not optimal in the diagnosis and follow-up of CD19 negative or dim B-ALLs. Though CD19 negative B-ALLs are rare, in the current era of CD19 targeted immuno-therapy, CD19 negative B-ALL relapses are frequent. We have presented our cohort of 14 de novo CD19 negative and dim B-ALLs and have highlighted the difficulties faced during diagnosis and MRD assessment of these patients. We have also discussed the need to identify alternative B-lineage gating markers and strategies to deal with such scenarios.

Outcomes of Intensive Treatment of Adult Acute Myeloid Leukemia Patients: A Retrospective Study From a Single Centre.

BACKGROUND: Acute Myeloid Leukemia (AML) is a very aggressive cancer with difficult treatment and poor outcomes. The treatment of these patients is quite challenging due to various reasons including the need for extensive supportive care, and high cost of therapy. Reports on outcomes from India are few. METHODS: We analyzed 93 adult patients (≥ 18 years) with AML who were treated with curative intent between 2007 and 2014. Patients received daunorubicin at dose of 60-90 mg/m2 and cytarabine 100 mg/m2 during induction and consolidation with 3 courses of high dose cytarabine (1.5-3 g/m2per dose for 6 doses per cycle). Only 4 patients underwent consolidation allogenic stem cell transplantation in first remission (CR1). RESULTS: The median age was 37 (18-66) years; males: 52%. Conventional cytogenetics (N = 63) showed 23% (N = 15), 56% (N = 35), 27% (N = 13) in good, intermediate risk and poor risk category respectively. FLT3-ITD was positive in 12/33 (36%) and NPM mutation in 7/23 (30%). Daunorubicin dose was 60 mg/m2 in 75% (N = 70) and 90 mg/m2 in 25% (N = 23) patients. Induction mortality was 17% (16/93) [60 mg/m2:19% (13/70), and 90 mg/m2:13% (3/23); p = 0.39)]. Complete remission was achieved by 60% (56/93) [60 mg/m2:53% (37/70), and 90 mg/m2:83% (19/23); p = 0.09)]. The median overall survival was 9.2 months and the actuarial survival at 2 years was 30%. By univariate analysis, FLT3-ITD positivity, white cell counts higher than 100,000/mm3 at presentation, and use of lower dose of daunorubicin in induction were associated with poorer outcomes. CONCLUSIONS: Outcomes in adult AML are generally poor. Many patients with high risk disease don't receive allogenic transplantation in CR1. Increased availability of allogenic stem cell transplantation may help to improve outcomes.

Chronic Myeloid Leukemia: Long-Term Outcome Data in the Imatinib Era.

Recent reports suggest that in the TKI era, the survival of chronic myeloid leukemia approaches that of general population. The real-world situation may be different. We analyzed patients (≥ 18 years) with chronic phase (CP) CML enrolled over a 7-year period (2002-2008) in an imatinib access program. Event was defined as non-achievement/loss of complete hematological response (CHR), loss of cytogenetic response or progression to accelerated (AP)/blast phase (BC). Progression was defined as development of AP/BC. Any delay of ≥ 1 week in reporting for drug refills was categorized as non-adherence. Of the 443 patients with CP-CML who started imatinib [median age: 36 years (18-70); High risk: 32% (Sokal) and 14% (Hasford/EUTOS)], 162 (37%) had received prior therapy [mostly hydroxyurea (N = 153]. CHR was achieved by 430 (97%). After a median follow up of 109.5 months (3.4-184.3), the EFS, PFS and OS at 10 years was 43%, 75% and 76% respectively. Superior EFS was predicted by low-risk Hasford score and adherence to therapy. Adherence to therapy was the only factor which predicted EFS on multivariate analysis (HR 0.64, 95% CI 0.50-0.83, P = 0.001). Long-term follow up of patients with CP-CML reflects poorer survival than those reported from clinical trials and reflects multiple issues that affect "real-world" patients. The continued drop in EFS, noted during long-term follow up, might take time to impact the PFS and OS due to the chronic nature of the disease. Sustained adherence to therapy is important for optimum long-term outcomes.
