The management of patients with advanced non-small-cell lung cancer (NSCLC) is becoming increasingly complex, with the identification of driver mutations/rearrangements and the development and availability of appropriate targeted therapies. In 2018, a group of medical oncologists with expertise in treating lung cancers used data from the published literature and experience to arrive at practical consensus recommendations for the treatment of advanced NSCLC for use by the community oncologists. These recommendations were subsequently published in 2019, with a plan to be updated annually. This article is an update to the 2019 consensus statement. For updating the consensus statement, a total of 25 clinically relevant questions on the management of patients with NSCLC on which consensus would be sought were drafted. The PubMed database was searched using the following terms combined with the Boolean operator “AND:” (lung cancer, phase 3, non-small cell lung cancer AND non-small-cell lung cancer [MeSH Terms]) AND (clinical trial, phase 3 [MeSH Terms]) AND (clinical trial, phase iii [MeSH Terms]). In addition, “carcinoma, non-smallcell lung/drug therapy” (MeSH Terms), “lung neoplasms/drug therapy” (MeSH), clinical trial, phase III (MeSH Terms) were used to refine the search. The survey results and literature were reviewed by the core members to draft the consensus statements. The expert consensus was that molecular testing is a crucial step to be considered for patients with NSCLC at baseline, and in those who progress on first-line chemotherapy and have not undergone any prior testing. For mutations/rearrangement-negative patients who progress on first-line immunotherapy, doublet or single-agent chemotherapy with docetaxel and/or gemcitabine and/or ramucirumab should be considered. Patients who progress on the newer anaplastic lymphoma kinase inhibitors should be considered for second-line therapy with lorlatinib or systemic chemotherapy. Maintenance therapy with pemetrexed is preferred for NSCLC with non-squamous histology and should be avoided in NSCLC with squamous histology.

Use of growth factor after high-dose chemotherapy (HDC) and autologous peripheral blood stem cell (PBSC) support is current standard in reducing days of neutropenia. This retrospective study aims to compare the efficacy of two standard growth factors, pegfilgrastim (PEG) and filgrastim (FIL) after HDC. We collected data on 195 consecutive adult patients who received an autotransplant (myeloma, lymphoma and others) between January 2004 and December 2014 at two tertiary care centres. The primary end point was the duration of neutropenia in terms of days to reach an ANC > 0.5 × 10(9)/L. Filgrastim was given to 110 patients and PEG was given to 85 patients. Time to engraftment, defined as the time to reach an ANC of 0.5 × 10(9)/L on 2 consecutive days after the day of auto-SCT, was 12.6 days with FIL compared with 12.1 days with PEG group (p = 0.126). When comparing the total days of severe neutropenia (WBC

We compared the lomustine, cytarabine, cyclophosphamide and etoposide (LACE) and BCNU, etoposide, cytarabine, melphalan (BEAM) conditioning regimens for toxicity, engraftment kinetics, and efficacy in 139 patients undergoing autologous hematopoietic stem cell transplant for primary refractory or relapsed lymphoma. Ninety-two patients with Hodgkin lymphoma and 47 with non-Hodgkin lymphoma were enrolled. Seventy-five patients received LACE while 64 received BEAM. The incidence of grade 3-4 oral mucositis (9 vs 38%; P < 0.001) and parenteral nutrition requirement (32 vs 69%; P < 0.001) were significantly lower in the LACE cohort. The median days to myeloid (10 vs 11; P = 0.007) and platelet engraftment (13 vs 15; P = 0.026) were shorter for the LACE cohort. Transplant-related mortality in the LACE group was 9% compared to 13% in patients treated with BEAM (P = NS). The probability of overall survival (OS) and progression-free survival (PFS) at 5 years for entire cohort was 46 and 41%, respectively. Probability of OS (LACE 46% vs BEAM 47%; P = NS) and PFS (LACE 37% vs BEAM 47%; P = NS) at 5 years was comparable between two groups. We conclude that LACE has better toxicity profile compared to BEAM and results in similar long-term survival in primary refractory or relapsed lymphoma transplant.

Engraftment Syndrome (ES) maybe observed in patients who undergo autologous stem cell transplant (SCT). To investigate clinical criteria for ES diagnosis and analyse the risk factors for this complication, we reviewed all auto-SCT cases (Lymphoma and Myeloma) performed during the past 9 years at two tertiary care centres. We analysed all patients with a non-infectious fever, developed within 7 days of engraftment (first day of ANC of 500 on two consecutive days) in 178 patients undergoing autologous stem cell transplant. A total of 46/178 (25.8%) patients developed non-infectious fever and one or more clinical signs of ES within 7 days of engraftment. In all, 29 (61%) fulfilled the Maiolino and 12 (26%) the Spitzer criteria. The incidence of engraftment syndrome using the Maiolino criteria in our study was 29 (15%), which compares well with Spanish study (13% using same criteria) and the original Maiolino study (20%). All patients with ES satisfactorily recovered and discharged with a median of 20 days from hospital. There was no significant difference in number of days of hospitalisation and days of antibiotics between the ES and non ES arms. All patients recovered without any morbidity and only 1 (2%) patient required readmission for fungal pneumonitis. 8 (17%) patients required ICU admission due to delay in initiation of steroids. None of the factors including number of chemotherapy cycles, conditioning regime, disease status, CD34 collection, growth factors and day of WBC engraftment except female (p = 0.064) were statistically significant (in univariate or multivariate analysis). Our study shows that engraftment syndrome is common in autologous transplant setting. Maiolino criteria to diagnose ES is more sensitive in our setting. If detected and treated early there is not much morbidity or mortality related to ES.

The management of locally advanced squamous cell carcinoma of the larynx is complex. Data from recent clinical trials have refined the use of existing therapies, such as radiation therapy and chemotherapy, and providing new treatment options, such as cetuximab. Selecting the most appropriate treatment for an individual patient requires a multidisciplinary approach and careful assessment of the relative advantages and disadvantages of each treatment approach. Chemoradiation is more effective than conventional radiation therapy, but also more toxic. Cetuximab plus radiation therapy is more effective than radiation alone and does not substantially increase radiation-related toxicity. Multimodality approach for laryngeal cancer has shown better organ preservation rates and survival. Ideally, multidisciplinary teams should weigh all these factors when making individual treatment decisions. Data from current trials will help further optimize multimodality treatment for Laryngeal Cancer.

Abstract 2023 Introduction: BCNU – containing regimens (CBV and BEAM) are commonly used in lymphoma transplants. LACE (lomustine-200 mg/ m2 × 1d, etoposide 1000mg/ m2 x1d, ara-c 2000 mg/m2x 2d and cyclophosphamide 1800mg/ m2 for 3d) is an effective and well tolerated regimen reported by few centers. We retrospectively compared the two types of conditioning regimens for toxicity, efficacy and outcome. Methods: One hundred and fifty five patients Hodgkin's disease (HD) and Non Hodgkin's lymphoma (NHL) with primary refractory or relapsed disease from August 1994- May 2011 were included in this study from 3 transplant centers in Mumbai, India. Seventy-nine patients received BEAM or CBV and 76 LACE. One-hundred two patients had HD (BEAM/CBV-50, LACE-52) while 52 had NHL (BEAM/CBV-28, LACE- 24).Stem cell source was peripheral blood (PBSC) in all but one patient in LACE group and 68 patients in BEAM/CBV group. Oral mucositis was graded by WHO criteria while all other toxicities by common toxicity criteria version-3. Total Parenteral Nutrition (TPN) was used in patients with poor oral intake. Neutrophil engraftment (NE) was defined as first day of ANC > 0.5 × 109/L and platelet engraftment (PE) as first of seven days of unsupported platelet count > 20 × 109/L. Sinusoidal Obstruction Syndrome (SOS) of the liver was recorded according to Seattle criteria. Categorical data was analyzed using chi-square while continuous data with Mann Whitney Test. Overall survival (OS) and progression-free survival (PFS) was analyzed using Kaplan Meier survival analysis. Results: The median age at transplant was comparable (BEAM/CBV-25 year, LACE-23 year). Eleven patients in BEAM/CBV group had chemotherapy refractory disease compared to 6 in LACE at the time of transplant (P=0.106).The median serum albumin level (BEAM/CBV -3.9 gm/dl, LACE- 3.9 gm/dl) at the time of diagnosis were comparable. Incidence of grade 3 and 4 oral mucositis was higher in BEAM/CBV compared to LACE group (45 % vs 10%; P Conclusion: In our retrospective multicenter analysis LACE is a better tolerated regimen with lesser toxicity, earlier engraftment and comparable survival rates. Randomized trials comparing it with BCNU- containing regimens are needed. Disclosures: No relevant conflicts of interest to declare.
