A Comparative Study Evaluating the Quality of Life and Survival Outcomes in Patients Receiving Chemotherapy Versus Oral Tyrosine Kinase Inhibitor in the Third Line and Beyond Setting for Advanced NSCLC.

Introduction: The outcomes in advanced NSCLC have improved owing to the availability of more effective systemic and improved supportive care. This has increased the number of patients who seek treatment in the third line and beyond setting. We conducted this study to compare the quality of life (QoL), toxicity, and outcomes in patients receiving chemotherapy and EGFR tyrosine kinase inhibitors (TKIs) in this setting. Methods: In this phase 3, randomized, open-label study, patients with stage III or IV NSCLC with disease progression on at least two prior lines of chemotherapy, with a life expectancy of at least 3 months, without prior EGFR TKI exposure, and stable brain metastases (if any) were included. Patients were randomized to receive chemotherapy (gemcitabine or docetaxel or paclitaxel or vinorelbine) or an EGFR TKI (erlotinib or gefitinib). The primary end point was the change in QoL at 8 to 10 weeks; the secondary outcomes were safety and overall survival (OS). Patients underwent clinical evaluation at every visit, and toxicity was assessed as per Common Terminology Criteria for Adverse Events version 4.03. A radiological tumor response assessment was done every 8 to 12 weeks from the start of therapy. The QoL was assessed using the EORTC QLQ C30 and LC13 questionnaires. The change in QoL scores was calculated as the difference between scores at baseline and scores at 8 to 10 weeks (Δ) for each QoL domain. The Mann-Whitney U test was used to compare the mean difference (Δ) for each domain. OS and progression-free survival (PFS) were determined using the Kaplan-Meier method and Cox proportional regression analysis. Results: A total of 246 patients were enrolled in the study, with 123 in each arm. There was a male predominance with 69.1% male patients in the chemotherapy arm and 70.7% in the EGFR TKI arm. The median age of patients in the chemotherapy arm was 54 years and 55 years in the chemotherapy and EGFR TKI arms, respectively. There was no significant difference in the change in QoL at baseline and the second visit (Δ) in both arms in all domains of EORTC QLQ C30 except cognitive function (p = 0.0045) and LC13 except alopecia (0.01249). The mean Δ Global Health Status was -28 in the chemotherapy arm and -26.8 in the EGFR TKI arm; this was not statistically significant (p = 0.973). The median follow-up was 88.1 months (95% confidence interval [CI]: 39.04-137.15). On the intention-to-treat analysis, the median PFS was 3.13 months (95% CI: 2.15-4.11) in the chemotherapy arm and 2.26 months (95% CI: 2.1-2.43) in the EGFR TKI arm, with hazard ratio at 1.074 (95% CI: 0.83-1.38) (p = 0.58). There were 120 deaths in each arm. The median OS was 7.63 months (95% CI: 5.96-9.30) in the chemotherapy arm and 7.5 months in the EGFR TKI arm (95% CI: 5.85-9.14); hazard ratio at 1.033 (95% CI: 0.80-1.33) (p = 0.805). The toxicity profile was similar in both arms except for a significantly higher incidence of fatigue (p = 0.043), peripheral neuropathy (0.000), alopecia, hypokalemia (0.037), and pedal edema (0.007) in the chemotherapy arm and dry skin (p = 0.000) and skin rash (p = 0.019) in the EGFR TKI arm. Conclusions: There was no significant difference in most QoL scales (except cognitive function and alopecia), OS, and PFS of patients with advanced NSCLC receiving an EGFR TKI as compared with chemotherapy TKI in the third-line setting. The toxicity profile is consistent with the known toxicities of the agents.

Quality of life and quality-adjusted time without toxicity in palliatively treated head-and-neck cancer patients.

BACKGROUND: Quality-adjusted time without toxicity (Q-TWiST) and quality of life (QOL) are indicators of benefit provided by different chemotherapy regimens. METHODS: This was a prospective study, in which adult head-and-neck (H and N) cancer patients, treated with metronomic chemotherapy were enrolled. The Functional Assessment of Cancer Therapy-General H and N (FACT-G and H and N) version 4 pro formas were self-administered before the start of chemotherapy and then at 2, 4, and 6 months. FACT QOL and Q-TWiST analysis were then performed. RESULTS: There was an improvement in the social well-being (P = 0.370), emotional well-being (P = 0.000), functional well-being (P = 0.000), H and N cancer subscale (P = 0.001), FACT H and N trial outcome index (P = 0.000), FACT G-total score (P = 0.000), and FACT H and N total score (P = 0.000) with palliative chemotherapy. The QTWiST value for a utility score of 0.25 for toxicity and relapse state was 145.93 days. CONCLUSION: Metronomic chemotherapy is associated with improvement in QOL and has a low duration of time spent in toxicity state.

Ceritinib in anaplastic lymphoma kinase-positive nonsmall cell lung cancer among patients who were previously exposed to crizotinib: Experience from the Indian subcontinent.

Ceritinib is a novel ALK inhibitor approved for advanced stage NSCLC with ALK gene rearrangement, progressed and/or intolerant to crizotinib. 13 patients were included in our study who received ceritinib. Majority of them were women and never smokers with a median age of 47 yrs. Nearly half of them had a compromised performance status and received ceritinib in third line and beyond. Ceritinib showed nearly 50% response rates. With a median follow up of 9 months for the entire cohort, median PFS and OS were not reached. However, the mean values for PFS and OS were 10.9 and 14.8 months,with an estimated 1 year PFS and OS being 56% and 78% respectively.1/3 of the patients had gastrointestinal and liver toxicities. Metabolic abnormalities were seen in 1/4 th of them. ceritinib was permanently discontinued in one patient due to pneumonitis. In conclusion, ceritinib has a favorable efficacy and side effect profile in our patient population., similar to that reported in large clinical trials. It has shown promising efficacy even in patients with compromised performance status; presence of brain metastases and heavily pre-treated disease.

Outcomes in non-metastatic treatment naive extremity osteosarcoma patients treated with a novel non-high dosemethotrexate-based, dose-dense combination chemotherapy regimen 'OGS-12'.

PURPOSE: High-dose methotrexate (HDMTX)-based regimens are widely used in osteosarcoma. However, mandatory in-patient treatment with complex pharmacokinetic monitoring requirement precludes its use, especially in resource-constrained settings of low- and middle-income countries (LMICs). METHODS: All treatment naive consecutive patients of osteosarcoma were prospectively treated on a novel institutional regimen (named OGS-12) comprising of eight sequential doublets of the following drugs: doxorubicin, cisplatin and ifosfamide in four courses each, given in the neoadjuvant and adjuvant settings. Data were prospectively collected on baseline characteristics, histological response to neoadjuvant chemotherapy (NACT), toxicity, event-free survival (EFS) and overall survival (OS). RESULTS: Between 2011 and 2014, 317 treatment naive patients with extremity osteosarcoma were seen, of whom 237 (75%) were non-metastatic. Majority had high tumour burden, with mean tumour size of 10.45 cm, high serum lactate dehydrogenase (LDH) and serum alkaline phosphatase (SAP) in 71% and 88% respectively. A significant number (34%) were nutritionally challenged. Two-hundred ten of 237 patients were analysable for histological response of which 58% had good response (viable cells ≤10%). At the median follow-up of 34.31 (2-60) months, in intention-to-treat (ITT) analysis, the 5-year EFS and OS were 56% and 75% respectively; the same were 60% and 80% in per-protocol analysis. There was febrile neutropenia (FN) in 56%, grade 3/4 thrombocytopaenia in 22% and anaemia in 47% with two chemotoxic deaths. Ten percent of the patients had grade 3/4 diarrhoea and stomatitis and one patient developed grade 4 acute kidney injury requiring dialysis. Baseline SAP (per-protocol) for EFS and performance status (ITT) for OS were found to be independent variables. Histological response was an independent predictor for EFS and OS in both the analyses. CONCLUSIONS: In treatment naive patients with non-metastatic osteosarcoma, OGS-12 protocol, a dose-dense, non-HDMTX-based, novel, economic and easy to administer regimen produces comparable outcomes to international standards, with acceptable toxicity and is worthy of wider clinical application.

EMERALD: Emergency visit audit of patients treated under medical oncology in a tertiary cancer center: Logical steps to decrease the burden.

BACKGROUND: We are a tertiary care cancer center and have approximately 1000-1500 emergency visits by cancer patients undergoing treatment under the adult medical oncology unit each month. However, due to the lack of a systematic audit, we are unable to plan steps toward the improvement in quality of emergency services, and hence the audit was planned. METHODS: All emergency visits under the adult medical oncology department in the month of July 2015 were audited. The cause of visit, the demographic details, cancer details, and chemotherapy status were obtained from the electronic medical records. The emergency visits were classified as avoidable or unavoidable. Descriptive statistics were performed. Reasons for avoidable emergency visits were sought. RESULTS: Out of 1199 visits, 1168 visits were classifiable. Six hundred and ninety-six visits were classified as unavoidable (59.6%, 95% CI: 56.7-62.4), 386 visits were classified as probably avoidable visit (33.0%, 95% CI: 30.4-35.8) whereas the remaining 86 (7.4%, 95% CI: 6.0-9.01) were classified as absolutely avoidable. Two hundred and ninety-seven visits happened on weekends (25.6%) and 138 visits converted into an inpatient admission (11.9%). The factors associated with avoidable visits were curative intention of treatment (odds ratio - 2.49), discontinued chemotherapy status (risk ratio [RR] - 8.28), and private category file status (RR - 1.89). CONCLUSION: A proportion of visits to emergency services can be curtailed. Approximately one-fourth of patients are seen on weekends, and only about one-tenth of patients get admitted.

ROS1 rearranged nonsmall cell lung cancer and crizotinib: An Indian experience.

ROS1 rearrangement acts as a driver mutation in 1-2% of NSCLC. Crizotinib is approved in this situation both in treatment naïve and pre-treated patients. Here we report our experience with crizotinib in patients with advanced NSCLC harbouring ROS1 rearrangement. Eleven patients were included in our study. More than half of our patients had associated comorbidities and one fourth of them had a compromised performance status. Out of 11 patients, 5 of them were exposed to crizotinib .The response rates among crizotinib treated patients was 80%. With a median follow up of 9 months, median PFS and OS were 5.4 months and 8.5 months respectively for the entire population. Analyzing the outcomes separately , median PFS and OS was not reached for those who received crizotinib compared to median PFS of 2.5 months and median OS of 4.2 months in those who were not exposed to crizotinib. The difference was statistically significant. Estimated 1 year OS was 80% for those who received crizotinib compared to 18% for who did not receive crizotinib. In conclusion, crizotinib is effective with acceptable side effect profile in patients with ROS1 rearranged NSCLC in our population.

Expectations and preferences for palliative chemotherapy in head and neck cancers patients.

BACKGROUND: Head and neck cancer patients undergoing palliative chemotherapy have a limited overall survival. Expectations and preferences of such patients towards palliative chemotherapy after explanation of disease prognosis and treatment options are unknown. METHODS: This was a single arm, prospective, observational study where newly diagnosed head and neck cancer patients warranting palliative chemotherapy underwent protocol defined counselling. Following counselling, they were administered chemotherapy expectation and preference proforma (CEP). The primary objective of this study was to estimate the percentage of patients opting for an increase in survival as the primary expectation from chemotherapy. RESULTS: We recruited two hundred patients all patients except one answered the CEP. Prolongation of life as the primary expectation from palliative chemotherapy was seen only in 82 patients (41.0%; 95% CI 34.4-47.9%). Symptom relief was the primary expectation or an equally important expectation amongst the remaining 117 patients (58.5%; 95% CI 51.6-65.1%). There was a statistically significant difference between the preferences of patients having a primary expectation of prolongation of life as opposed to symptom relief regarding the minimum expected number of patients need to treat to get prolongation of life (p value -0.00). The minimum expected increment in life expectancy for taking palliative chemotherapy was ">1year" in 190 patients (94.5%; 95% CI 91.5-97.7%). CONCLUSION: The primary expectation from palliative chemotherapy in head and neck cancer patients is not necessarily living longer in all patients. The magnitude of benefit preferred by the patients from chemotherapy far exceeded the current standards for drug approval.
