Real-World Data on Treatment Outcome of ALK-Positive Non-Small Cell Lung Cancer from an Indian Multicentric Cancer Registry.

Lalatendu Moharana The Anaplastic lymphoma kinase inhibitors (ALKi) represent the standard of care for metastatic non-small cell lung cancer (NSCLC) patients with EML4-ALK rearrangements. Various ALKi agents are available; however, not all eligible patients receive treatment with them due to various reasons. Given the limited real-world data available in our country, we aimed to assess treatment outcomes through a multicenter collaboration. This retrospective, multi-institutional study was conducted under the Network of Oncology Clinical Trials India and included a total of 67 ALK-positive metastatic lung cancer patients from 10 institutes across India, with a median follow-up of 23 months. In the first line setting, the objective response rate (ORR) with ALKi was 63.6% (crizotinib: 60.7%, ceritinib: 70%, alectinib: 66.6%, p = 0.508), while with chemotherapy, it was 26.1%. The median progression-free survival (mPFS) for the first line ALKi group was significantly higher than that for chemotherapy (19 vs. 9 months, p = 0.00, hazard ratio [HR] = 0.30, 95% confidence interval [CI]: 0.17-0.54). The mPFS for crizotinib, alectinib, and ceritinib was 17, 22, and 19 months, respectively ( p = 0.48). Patients who received ALKi upfront or after 1 to 3 cycles of chemotherapy or after 4 or more cycles of chemotherapy had mPFS of 16, 22, and 23 months, respectively ( p = 0.47). ALKi showed superior mPFS compared to chemotherapy in the second line (14 vs. 5 months; p = 0.002) and the third line (20 vs. 4 months; p = 0.009). The median overall survival (OS) was significantly better in patients who received ALKi in any line of therapy (44 vs. 14 months, p < 0.001, HR = 0.10, 95% CI: 0.04-0.23). Brain progression was higher among those who did not receive ALKi (69.2 vs. 31.5%). In conclusion, the use of ALKi as first line treatment for ALK-positive metastatic NSCLC patients resulted in improved PFS. PFS and ORR did not significantly differ between patients who received ALKi upfront or after initiating chemotherapy. Notably, patients who received ALKi in second or later lines demonstrated significantly better outcomes compared to those receiving chemotherapy. The use of ALKi in any line of therapy was associated with significantly prolonged OS.

Practical Consensus Guidelines for the Use of S-1 in GI Malignancies.

Purvish M ParikhS-1 (5-fluorouracil prodrug [tegafur] in combination with 5-chloro-2,4-dihydroxypyridine [CDHP] and potassium oxonate [OXO]) was first approved in 1999. In order to make it easy for community oncologists, we decided to put together this expert consensus guideline for its use in gastrointestinal (GI) malignancies. A total of 15 subject matter experts used modified Delphi method to discuss, analyze, and vote on key aspects regarding practical approach to use of S-1 in GI cancers, a process involving 6 months of work. The consensus guidelines specify how S-1 use can be optimized in patients with colorectal, gastric, and pancreatic tumors. The voting for the 17 key points resulted in a majority consensus for all the statements (approval ranging from 13/15 [87%] to 15/15 [100%]). S-1 is a combination of three drugs (tegafur, CDHP, and OXO) specifically designed to reduce toxicity and enhance efficacy; clinical data and meta-analysis confirm both factors; and it is recommended as standard of care for GI cancers. S-1 is approved and one of the standards of care for all lines of therapy in colorectal cancer and pancreatic cancers. S-1 with oxaliplatin is the standard of care for gastric cancers.

PD-L1 expression in head and neck squamous cell carcinoma and its clinical significance: A prospective observational study from a tertiary care centre.

BACKGROUND: Programmed Death Ligand 1 (PD-L1) expression in tumor cells contribute to tumor immunity and therapies directed against it, have shown encouraging results in recent years. As there is limited data on the significance of PD-L1 expression in Head and Neck Squamous Cell Carcinoma (HNSCC) from India, we aimed to study the PD-L1 expression and its relation with different clinic-pathological parameters in patients of HNSCC from a tertiary care center in Eastern India. METHODS: A prospective evaluation of HNSCC patients diagnosed and managed at our center over a period of two and half years, was performed. PD-L1 expression in formalin fixed-paraffin embedded tumor tissue specimens was measured using SP-263 (Ventana) and 22C3 (Dako). A PD-L1 expression of <1%, 1-19%, ≥20% were considered negative, low, and high expression, respectively, and was correlated with various parameters. RESULTS: A total of 71 patients (mean age 50.8 ± 13.3 years, 86% males) were diagnosed with HNSCC (buccal mucosa-28, tongue-22, rest of oral cavity-8, larynx-7, nasopharynx-6). The tumor was poorly differentiated in 12 (17%). PD-L1 positivity was seen in a total of 51 (71.8%) patients (1-19%:18, ≥20%:33). Thirty (85.7%) patients among those aged <50 years and 58.3% of those aged ≥50 years showed PD-L1 positivity which was significant (P = 0.01). There were no statistically significant differences in PD-L1 positivity with respect to gender, tobacco use, tumor grade as well as tumor and nodal stage. Median follow up duration was 18 months (range 3-31 months) and there was significant difference in overall survival among PD-L1 positive and negative groups (31 vs 24 months; log rank P = 0.03). CONCLUSIONS: 72% of HNSCC patients in our cohort showed PD-L1 positivity and it was not associated with any patient demographic characteristics or aggressive pathological features. Positive PD-L1 expression may have a beneficial effect on overall survival in HNSCC.

PD-L1 expression and its significance in advanced NSCLC: real-world experience from a tertiary care center.

BACKGROUND: Targeted therapies against programmed death ligand-1 (PD-L1) in non-small cell lung cancer (NSCLC) have revolutionized the management in recent years. There is paucity of data on the significance of PD-L1 expression in NSCLC from India. We aimed to study the prevalence of PD-L1 expression and its relation with different clinico-pathological parameters in advanced NSCLC from a tertiary care center in Eastern India. METHODS: All consecutive patients with advanced NSCLC diagnosed from January 2020 to December 2021 were prospectively evaluated for PD-L1 expression in formalin fixed-paraffin embedded tumor tissue specimens using immunohistochemistry analysis. A PD-L1 expression of < 1%, 1-49%, and ≥ 50% were considered negative, low, and high expression positive respectively, and association with various parameters was performed. RESULTS: Out of the 94 patients (mean age 59.6 ± 14 years and 63.8% males), PD-L1 positivity was seen in 42 (44.7%) patients, with low positivity (1-49%) in 29 patients and high positivity (≥ 50%) in 13 patients. Epidermal Growth Factor Receptor (EGFR) mutations were seen in 28 patients (29.8%). There were no significant differences in PD-L1 positivity with respect to gender, age, and molecular mutation status. PD-L1 positivity was significantly associated with tobacco use (p = 0.04), advanced tumor stage (p < 0.001), and higher nodal stage (p < 0.001). Median overall survival in the cohort was 17 months and it was not significantly different between the PD-L1 positive and negative groups. CONCLUSIONS: Forty-five percent of advanced NSCLC patients in our cohort showed positive PD-L1 expression and it is associated with tobacco use and aggressive tumor characteristics.

Daratumumab in Indian patients with relapsed and refractory multiple myeloma: a prospective, multicenter, phase IV study.

Aim: To assess the safety and effectiveness of daratumumab monotherapy in Indian patients with relapsed/refractory multiple myeloma. Methods: In this prospective, multicenter, phase IV study, patients (aged ≥18 years) received intravenous daratumumab (16 mg/kg) in six cycles. Safety was the primary end point. Results: Of the 139 patients included, 121 (87.1%) experienced ≥1 treatment-emergent adverse events (TEAEs; 53 [38.1%] drug-related), 32 (23%) had ≥1 serious TEAEs (five [3.6%] drug-related) and 16 (11.5%) deaths were reported (one death [0.7%] was drug-related). Overall response rate was 26.3%; 62.7% of patients had stable disease. Median time to first response and median progression-free survival were 5.2 and 5.9 months, respectively. Functional status and well-being were improved. Conclusion: Daratumumab showed an acceptable and expected safety profile with consistent efficacy, providing a novel therapeutic option for relapsed/refractory multiple myeloma management in India.

Daratumumab is a monoclonal antibody approved for the treatment of patients with relapsed/refractory multiple myeloma (RRMM). This study evaluated the outcome of daratumumab single therapy in Indian patients who were not cured with other drugs used for the same disease. 139 adult patients were included in this study from 15 institutes across India. Daratumumab (16 mg/kg) was diluted with 500 or 1000 ml of saline solution and given slowly through the intravenous route 16-times within 6 months. The study examined whether the safety profile and benefits of daratumumab reported in Indian patients were similar to those reported in the RRMM populations of other countries. The study found that most of the adverse events were not severe and could be easily treated by the study physician. 16 patients died (one might have been due to daratumumab treatment). Daratumumab treatment provided life support and recovery benefits to many patients. Daratumumab single therapy provides an appropriate and acceptable safety profile with no new adverse events and consistent benefits in RRMM patients.

Practical Clinical Consensus Guidelines for the Management of Cancer Associated Anemia in Low- and Middle-Income Countries.

Purvish M. ParikhCancer-associated anemia (CAA) remains a major unmet need that compromises overall survival (OS) and quality of life (QoL). Currently, available guidelines do not take into consideration the unique challenges in low- and middle-income countries (LMIC). Our CAA patients have to battle preexisting impaired nutritional status, depleted body iron stores, financial limitations, and difficulty in having easily accessible affordable healthcare. Hence, we fulfilled the need of guidelines for LMIC. A group of subject experts were put together, given background literature, met in a face-to-face discussion, voted using Delphi process, and finally agreed on the contents of this guideline document. As many as 50% of cancer patients will have significant anemia (hemoglobin < 10 g/dL) at initial diagnosis. It is most commonly seen with gastrointestinal malignancies, head and neck cancers, and acute leukemias. The hemoglobin falls further after initiation of cancer directed therapy, due to chemotherapy itself or heightened nutritional deficiency. Its evaluation should include tests for complete blood count, red blood cell morphology, reticulocyte count, Coombs test, and levels of vitamin B12 and folic acid. Iron status should be monitored using test to measure serum iron, total iron binding capacity, transferring saturation, and serum ferritin levels. A minimum of 50% of cancer patients with anemia require iron supplements. The preferred mode of therapy is with intravenous (IV) iron using ferric carboxymaltose (FCM). Most patients respond satisfactorily to single dose of 1000 mg. It is also safe and does not require use of a test dose. Significant anemia is found in at least half of all cancer patients in India, South Asian Association for Regional Cooperation region, and other LMIC countries. Its awareness among healthcare professionals will prevent it from remaining undiagnosed (in up to 70% of all cancer patients) and adversely affecting OS and QoL. The benefits of treating them with IV iron therapy are quick replenishment of iron stores, hemoglobin returning to normal, better QoL, and avoiding risk of infections/reactions with blood transfusions. Many publications have proven the value of single-dose FCM in such clinical situations. CAA has been proven to be an independent prognostic factor that adversely affects both QoL and OS in cancer patients. Use of FCM as single IV dose of 1000 mg is safe and effective in the majority of patients with CAA.

A Real-World Study of Safety, Immunogenicity and Efficacy of Bevacizumab in Patients With Solid Malignancies: A Phase IV, Post-Marketing Study in India.

Objective: The aim of this study was to evaluate the post-marketing safety, tolerability, immunogenicity and efficacy of Bevacizumab (manufactured by Hetero Biopharma) in a broader population of patients with solid tumors. Patients And Methods: This phase IV, prospective, multi-centric clinical study was carried out in Indian patients with solid malignancies (metastatic colorectal cancer, non-squamous non-small-cell lung cancer, metastatic renal cell carcinoma) treated with Bevacizumab between April 2018 and July 2019. This study included 203 patients from 16 tertiary care oncology centers across India for safety assessment, of which a subset of 115 patients who have consented were also evaluated for efficacy and immunogenicity. This study was prospectively registered in the Clinical Trial Registry of India (CTRI), and was commenced only after receiving approval from the competent authority (Central Drugs Standard Control Organization, CDSCO). Results: Out of the 203 enrolled patients, 121 (59.6%) patients reported 338 adverse events (AEs) during this study. Of 338 reported AEs, 14 serious adverse events (SAEs) were reported by 13 patients including 6 fatal SAEs, assessed as unrelated to the study medication and 7 non-fatal SAEs, 5 assessed as related, and 3 unrelated to Bevacizumab. Most AEs reported in this study (33.9%) were general disorders and administration site conditions, followed by gastrointestinal disorders (29.1%). The most frequently reported AEs were diarrhea (11.3%), asthenia (10.3%), headache (8.9%), pain (7.4%), vomiting (7.9%), and neutropenia (5.9%). At the end of the study, 2 (1.75%) of 69 patients reported antibodies to Bevacizumab without affecting safety and efficacy. However, at the end of 12 months, no patient had reported antibodies to Bevacizumab. Complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD) were reported in 18.3%, 22.6%, 9.6%, and 8.7% of patients, respectively. The overall response rate (CR + PR) was reported in 40.9% of patients at the end of the study. Disease control rate (DCR), also known as the clinical benefit rate (CBR) was reported in 50.4% of patients. Conclusions: Bevacizumab (Cizumab, Hetero Biopharma) was observed to be safe, well tolerated, lacking immunogenicity, and efficacious in the treatment of solid tumors. The findings of this phase IV study of Bevacizumab, primarily as a combination therapy regimen suggest its suitability and rationality for usage in multiple solid malignancies.

Rituximab biosimilar for the treatment of diffuse large B-cell lymphoma: a phase 3 randomized study in India.

PURPOSE: Very few studies have demonstrated the rituximab biosimilarity in terms of efficacy, safety, pharmacokinetics, pharmacodynamics, and immunogenicity in patients with diffuse large B-cell lymphoma (DLBCL) in India. Therefore, we compared the efficacy, safety, pharmacokinetic, pharmacodynamic, and immunogenicity of our biosimilar rituximab with the reference rituximab (Ristova, Roche products [India] Pvt. Ltd) in patients with DLBCL in India. METHODS: A phase 3, randomized, assessor-blind, parallel-group, two-arm study was conducted across 28 sites in India. A total of 153 newly diagnosed DLBCL patients were randomized to receive either biosimilar rituximab or reference rituximab. The study drugs were administered at a dose of 375 mg/m2 by intravenous infusion every 3 weeks for six cycles. The primary end point was objective response rate (ORR) at the end of Cycle 6. Secondary end points included: pharmacokinetic, pharmacodynamics, immunogenicity, and safety assessment. RESULTS: The ORR at the end of Cycle 6 was 82.14% in the biosimilar rituximab and 85.71% in the reference rituximab group. The risk difference (90% CIs) was - 3.57 (- 14.80, 7.66). It met the non-inferiority margin of - 20%. The pharmacokinetic and pharmacodynamic parameters were comparable between the two treatment groups. The incidence rate of immunogenicity was very low and similar in both the treatment groups. The safety profile of both the treatments was comparable with no major difference in terms of nature, frequency and severity of TEAEs. CONCLUSION: The study demonstrated the biosimilarity between the biosimilar rituximab and the reference rituximab. Our biosimilar rituximab could add to the cost-effective treatment alternatives for patients with DLBCL in India.

EVI1 upregulates PTGS1 (COX1) and decreases the action of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia cells.

Tyrosine kinase inhibitors (TKIs) are highly effective in treating chronic myelogenous leukemia (CML). However, primary and acquired drug resistance to TKIs have been reported. In this study, we used RNA sequencing followed by RQ-PCR to show that the proto-oncogene EVI1 targets the drug-metabolizing gene PTGS1 in CML. The PTGS1 promoter element had an EVI1 binding site, and CHIP assay confirmed its presence. Data from a publicly available CML microarray dataset and an independent set of CML samples showed a significant positive correlation between EVI1 and PTGS1 expression in CML. Downregulation of EVI1 in K562 cells and subsequent treatment with TKIs resulted in a lower IC50 in the control cells. Furthermore, combined inhibition of BCR-ABL with imatinib and PTGS1 with FR122047 (PTGS1 inhibitor) synergistically reduced the viability of imatinib-resistant K562 cells. We conclude that elevated EVI1 expression contributes to TKIs resistance and that combined inhibition of PTGS1 and BCR-ABL may represent a novel therapeutic approach.

Correction: Rucaparib as a Salvage Treatment in Platinum-Sensitive Relapsed Ovarian Carcinoma: A Case Report.

[This corrects the article DOI: 10.7759/cureus.30405.].

Rucaparib as a Salvage Treatment in Platinum-Sensitive Relapsed Ovarian Carcinoma: A Case Report.

One of the leading causes of female mortality worldwide is ovarian carcinoma. It can be divided into five main types: high-grade serous, endometrioid, clear cell, mucinous and low-grade serous carcinomas. These tumors represent distinct diseases and prognoses. Though the conventional treatment using platinum-based chemotherapy typically results in an adequate initial response, recurrence is not uncommon. The present case report deals with treating one such platinum-sensitive first relapse of high-grade serous ovarian carcinoma with a poly (ADP-ribose) polymerase (PARP) inhibitor. Here, rucaparib, one of the Food and Drug Administration (FDA)-approved PARP inhibitors, was used to treat platinum-sensitive relapse in a patient with germline breast cancer (BRCA) negative ovarian cancer. The patient showed a complete response to the treatment and was in remission for around 11 months with only one dose reduction and no blood transfusion. The patient also remained progression-free on regular follow-ups. Since the outcome for this individual case was good, a more extensive study with rucaparib as a second-line treatment option in gene 1 BRCA wild-type homologous recombination deficiency (HRD)-positive ovarian carcinoma patients can be explored.

CONCORDANCE: A real-world evidence study to evaluate the concordance of detecting epidermal growth factor receptor (EGFR) mutation by circulating tumor DNA* versus tissue biopsy in patients with metastatic non-small cell lung cancer.

Background: Molecular tissue testing in non-small cell lung cancer (NSCLC) is done for the assessment of epidermal growth factor receptor (EGFR) mutation. EGFR mutation status is the basis for deciding the targeted treatment option for patients with metastatic NSCLC. The nonavailability of tissue samples and contraindications for biopsy pose a significant challenge. Hence, circulating tumor DNA (ctDNA) by liquid biopsy can be a viable alternative for NSCLC patients. Methods: This study was conducted at 15 sites across India. EGFR mutation testing from plasma was done as part of the study at the central laboratory by the next-generation sequencing (NGS) method, and EGFR mutation test results from tissue samples (done as part of routine practice) were recorded for all the patients. Results: Out of the total patients enrolled (N = 245), the majority (64.5%, n = 158) were men. The median age of patients was 58.0 (range: 26-84) years. The concordance between plasma and tissue testing was found to be 82.9% (95% confidence interval [CI]: 77.55, 87.45). The sensitivity and specificity of NGS were 68.4% (95% CI: 56.92, 78.37) and 90.1% [95% CI: 84.36, 94.21), respectively. Plasma testing detected 1.2% (n = 3) and tissue sample testing detected 2.4% (n = 6) positive status of exon 20 T790M EGFR mutation. Out of the total number of patients enrolled, 25 were tissue positive and plasma negative, while 16 were plasma positive and tissue negative. Conclusions: "> This real-world study in Indian patients suggests that plasma testing for EGFR mutation analysis is a viable diagnostic option in newly diagnosed advanced/metastatic NSCLC patients. The noninvasive plasma procedure in patients without available/evaluable tumor sample may enable more patients to receive appropriate targeted therapies by providing clinicians with valuable insights into the patient's tumor mutation status.

Sequencing of Systemic Therapies in the Management of Advanced Prostate Cancer in India: a Delphi-Based Consensus.

INTRODUCTION: With the availability of an increasing number of therapeutic options for advanced prostate cancer (APC), optimal sequencing and combination of therapies have emerged to be the areas of challenges. In the Indian context, there is a dearth of consensus recommendations to guide clinicians regarding optimal sequencing of therapy in APC management. A Delphi-based consensus regarding optimal therapy sequencing in APC management was developed by an expert panel of medical oncologists from across India. METHODS: An expert scientific committee of 11 medical oncologists and an expert panel of 53 medical oncologists from India constituted the panel for the Delphi consensus. In the first phase, a questionnaire with 41 clinical statements was developed in several critical controversial areas in APC treatment. In the second phase, 29 clinical statements were reworked and sent to eight experts to obtain their opinions on best practices. The consensus ratings were based on a 9-point Likert scale. Based on the overall response, statements with a mean score of ≥ 7 with 1 outlier were considered as "consensus." RESULTS: Degarelix was the preferred androgen deprivation therapy (ADT). While ADT plus docetaxel was the preferred option for metastatic castrate-sensitive/naïve prostate cancer patients with high-volume disease, ADT with abiraterone was the preferred choice for low-volume disease. Docetaxel was the preferred first-line treatment option in men who received ADT alone in the castrate-sensitive/naïve setting. For patients progressing on or after docetaxel for metastatic castrate-resistant prostate cancer (without prior abiraterone or enzalutamide), the experts reached a consensus on the use of enzalutamide as the preferred second-line treatment option. No consensus was reached for the third-line treatment options. CONCLUSION: This article is intended to serve as a guide to help clinicians discuss with their patients as part of the shared and multidisciplinary decision-making for improved APC management in India.

Fixed dose combination of capecitabine and cyclophosphamide in metastatic breast cancer: Results from THE ENCLOSE phase 2/3 randomized multicenter study.

AIM: To evaluate pharmacokinetics, efficacy and safety of fixed-dose combination (FDC) of oral capecitabine + cyclophosphamide in metastatic breast cancer (MBC) patients progressing after anthracycline and/or taxane chemotherapy. METHODS: In this prospective, adaptive, phase-2/3, open-label study (CTRI/2014/12/005234), patients were randomized (1:1:1) to three FDC doses (doses/day: D1, capecitabine + cyclophosphamide 1400 mg + 60 mg; D2, 1800 mg + 80 mg; D3, 2200 mg + 100 mg) for 14 days, in 21-day cycles. In Part-I, multiple-dose pharmacokinetics and optimal dose(s) were evaluated with futility analysis. Group(s) with <3 responders based on best overall response rate (BOR, complete response [CR]+partial response [PR]), were discontinued. Efficacy (BOR, disease control rates [DCR; CR + PR + stable disease]) and safety of optimal dose(s) were evaluated in Part-II. RESULTS: Of 66 patients (n = 22/group) in Part-I, pharmacokinetics (D1 = 7/22, D2 = 9/22, D3 = 8/22) showed dose-proportionality for cyclophosphamide and greater than dose-proportionality for capecitabine. Modified intent-to-treat (mITT) analysis showed BOR of 7.14% (1/14) in D1 (discontinued), and 22.22% (4/18) each in D2 and D3, respectively. In Part-II, 50 additional patients were randomized in D2 and D3 (n = 144; total 72 [22 + 50] patients/group). mITT analysis in D2 (n = 54) and D3 (n = 58) showed BOR of 29.63% (16/54, 95%CI: 17.45-41.81%) and 22.41% (13/58, 95%CI: 11.68-33.15%), respectively. DCR in D2 and D3 were 87.04% (47/54, 95%CI: 78.08-96.00%) and 82.76% (48/58; 95%CI: 73.04-92.48%) after 3 and 57.41% (31/54; 95%CI: 52.41-79.50%) and 50.00% (29/58; 95%CI: 40.40-67.00%), after 6-cycles, respectively. Hand-foot syndrome (16.67%), vomiting (9.72%) in D2, and hand-foot syndrome (18.06%), asthenia (15.28%) in D3 were most-common adverse events. CONCLUSION: FDC of capecitabine + cyclophosphamide (1800 + 80 mg/day) showed high disease control rates and good safety profile in MBC patients.

Cutaneous involvement in diffuse large B cell lymphoma at presentation: report of two rare cases and literature review.

BACKGROUND: Diffuse large B cell lymphoma (DLBCL) can occur at nodal and/or extra-nodal sites. After the gastrointestinal tract, cutaneous involvement predominates in extra-nodal DLBCL. Skin involvement at presentation can be in the form of plaques, papules, nodules or ulcers. Differentiating primary cutaneous DLBCL from systemic DLBCL with cutaneous involvement is important for appropriate patient management. CASE PRESENTATION: We describe here, two interesting cases of skin involvement in DLBCL- one primary cutaneous DLBCL and the other, cutaneous involvement in systemic DLBCL with different clinico-pathological profiles. Though both cases had almost similar morphology of the skin lesions (ulcero-proliferative) at presentation, the disease was confined to the skin in the former, while the latter had involvement of lymph nodes and bone marrow. CONCLUSIONS: Meticulous clinical evaluation, appropriate histopathological and immunohistochemical workup helped in their diagnosis and correct classification of the disease status, guiding the further treatment decisions.

Efficacy and safety of nanosomal docetaxel lipid suspension-based chemotherapy in squamous cell carcinoma of the head and neck: A multicenter retrospective study.

Squamous cell carcinoma of the head and neck (SCCHN) is the most common cancer in Indian men. Docetaxel alone or in combination with other chemotherapeutic agents is recommended for the management of SCCHN. The present multicenter, retrospective study was conducted to evaluate the efficacy and safety of a novel docetaxel formulation 'nanosomal docetaxel lipid suspension (NDLS)'-based chemotherapy in SCCHN. The medical records of patients with SCCHN, who were treated with NDLS-based chemotherapy and followed up between August 2014 and September 2018, were reviewed. The efficacy endpoints were overall response rate [ORR; complete response (CR) + partial response (PR)] and disease control rate (DCR; CR + PR + stable disease) for patients receiving NDLS-based induction or palliative chemotherapy. Overall survival (OS) and safety were also evaluated. Efficacy evaluation was available in 30/34 patients (induction, 20/23; palliative, 10/11). NDLS-based induction chemotherapy showed an ORR and DCR of 95% and a median OS of 43.5 months (follow-up duration, 0.6-80.3 months). For NDLS-based palliative chemotherapy, the ORR and DCR were 50% and the median OS time was 4.6 months (follow-up duration, 1.8 to 14.3 months). At least one adverse event was reported in 82.6% patients. No new safety concerns were reported. Overall, NDLS-based chemotherapy was effective and well tolerated in the treatment of SCCHN.

Efficacy and safety of nanosomal docetaxel lipid suspension based chemotherapy in gastric and gastroesophageal junction adenocarcinoma.

The current retrospective multicenter study evaluated the efficacy and safety of nanosomal docetaxel lipid suspension (NDLS; DoceAqualip) based chemotherapy in patients with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The medical charts of patients with gastric and GEJ adenocarcinoma, who were treated with NDLS (50-75 mg/m2; 3 weekly cycles) based chemotherapy and followed-up from April 2014 to September 2018, were analyzed. The study endpoints included overall response rate (ORR) and disease control rate (DCR) in neoadjuvant and metastatic settings. Overall survival (OS) and safety were also evaluated. Of the 43 patients with gastric (n=39) and GEJ (n=4) adenocarcinoma, efficacy evaluation was available in 35 (neoadjuvant, 17/18 patients; metastatic, 18/25 patients). In the neoadjuvant setting, an ORR of 58.82% and a DCR of 94.11% were observed, whereas in the metastatic setting, the ORR was 77.77% and the DCR was 83.33%. In the neoadjuvant setting, at a follow-up ranging from 0.7 to 41.2 months, the median OS was not reached. In the metastatic setting, the median OS was 31.9 months at a follow-up ranging from 0.2 to 50.3 months. At least one adverse event (AE) was reported in 24 patients. Anemia, lymphopenia and thrombocytopenia were the most common hematological AEs, while nausea, vomiting and weakness were the most common non-hematological AEs. NDLS based treatment was well-tolerated without any new safety concerns. Overall, NDLS-based chemotherapy was effective and well-tolerated in the management of gastric and GEJ adenocarcinoma.

Nanosomal Docetaxel Lipid Suspension-Based Chemotherapy in Breast Cancer: Results from a Multicenter Retrospective Study.

PURPOSE: The purpose of this study was to evaluate the efficacy and safety of nanosomal docetaxel lipid suspension (NDLS, DoceAqualip)-based chemotherapy in breast cancer. METHODS: Medical charts of patients with breast cancer, who were treated and followed up with NDLS (75-100 mg/m2; 3-week cycle)-based chemotherapy from August 2014 to September 2018, were analyzed in this multicenter, retrospective study. The study endpoints were overall response rate (ORR: complete response [CR]+partial response [PR]) and disease control rate (DCR: CR+PR+stable disease [SD]) in neoadjuvant and metastatic settings. Overall survival (OS) and safety were evaluated for all settings. RESULTS: Of 91 patients (neoadjuvant: 12, adjuvant: 61, metastatic: 18), efficacy evaluation in 29 patients (neoadjuvant: 12/12, metastatic: 17/18) demonstrated an ORR and DCR of 100%, respectively, in the neoadjuvant setting, and an ORR of 64.7% and DCR of 70.6%, respectively, in the metastatic setting. At a median follow-up of 21.6 months (range: 2.1 to 49.9 months), median OS was not reached in neoadjuvant and adjuvant settings, and it was 30.4 months in metastatic settings. At least one adverse event (AE) was reported in 59.3% of patients. Anemia, thrombocytopenia, lymphopenia, and neutropenia were the most common hematological AEs reported while hyperglycemia and alteration in liver function tests were the most common non-hematological AEs. NDLS-based treatment was well tolerated without any new safety concerns. CONCLUSION: Nanosomal docetaxel lipid suspension-based chemotherapy was efficacious and well tolerated in the treatment of breast cancer. Further, NDLS is being evaluated prospectively in patients with triple-negative breast cancer (ClinicalTrials.gov: NCT03671044).

Management of Lymphomas: Consensus Document 2018 by an Indian Expert Group.

The clinical course of lymphoma depends on the indolent or aggressive nature of the disease. Hence, the optimal management of lymphoma needs a correct diagnosis and classification as B cell, T-cell or natural killer (NK)/T-cell as well as indolent or high-grade type lymphoma. The current consensus statement, developed by experts in the field across India, is intended to help healthcare professionals manage lymphomas in adults over 18 years of age. However, it should be noted that the information provided may not be appropriate to all patients and individual patient circumstances may dictate alternative approaches. The consensus statement discusses the diagnosis, staging and prognosis applicable to all subtypes of lymphoma, and detailed treatment regimens for specific entities of lymphoma including diffuse large B-cell lymphoma, Hodgkin's lymphoma, follicular lymphoma, T-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, Burkitt's lymphoma, and anaplastic large cell lymphoma.

A Prospective, Randomized, Multiple-Dose, Multi-Center, Comparative Clinical Study to Evaluate the Efficacy, Safety, Immunogenicity of a biosimilar Bevacizumab (Test product, Hetero) and Reference Medicinal Product (Bevacizumab, Roche) in Patients of Metastatic Colorectal Cancer.

OBJECTIVE: :To compare efficacy and safety of a biosimilar, Bevacizumab (Hetero) vs reference medicinal product (Bevacizumab, Roche) as first line therapy in patients with metastatic colorectal cancer (mCRC) in combination with chemotherapy. METHODS: Patients of aged 18 to 65 with histologically pre-confirmed mCRC and treatment naïve with unresectable metastatic disease or distant metastases were enrolled and randomized to receive either Hetero-Bevacizumab or RMPBevacizumab along with chemotherapy (XELOX or FOLFOX-4) regimen over a period of 24 weeks (up to 8 cycles of Hetero-Bevacizumab/RMP-Bevacizumab+ XELOX regimen (each cycle of 3 weeks) or up to 12 cycles of Hetero-Bevacizumab/ RMP-Bevacizumab + FOLFOX-4 regimen (each cycle of 2 weeks). Bevacizumab was administered at 7.5 mg/kg as an IV infusion over 60-90 minutes on Day 1 of each treatment cycle. The efficacy endpoints were the overall response rate (CR+PR) and disease control rate (DCR) according to RECIST 1.1. The safety endpoints included assessments of treatment emergent adverse events and immunogenicity. RESULTS: 160 patients were screened; 111 patients were randomized in the study. No statistical significant difference in overall response rate between both the treatment groups (HB-MAB vs. RB-MAB: 35.56 % vs. 20%, P=0.28 at Week 6; 37.50 % vs. 30.77 %, P=0.73 at Week 12). Similar trend was observed for disease control rate (HB-MAB vs. RB-MAB: 100% vs. 96%, P=0.36 at Week 6; 95.83 vs. 100%, P=1.00 at Week 12). CONCLUSIONS: Herero's Bevacizumab was found to be comparable to reference medical product, Bevacizumab in terms of efficacy and tolerability for the Indian patients with metastatic colorectal cancer.
