RESUMO
No study has unequivocally proven that chemotherapy prolongs overall survival (OS) in advanced esophageal cancer. We conducted a Phase III randomized study in first-line advanced unresectable/metastatic esophageal/GEJ cancer. Patients aged 18-70 years, with performance status 0-2, were randomized to best supportive care (BSC) alone, or BSC with weekly paclitaxel 80 mg/m2. BSC comprised, as indicated, education, counselling, radiation, stenting, feeding tube placement, nutritional supplementation, medications like analgesics, and referral to a support group and palliative care. The primary endpoint was OS; secondary endpoints included progression free survival (PFS), response, toxicity, and QoL. Between May 2016-December 2020, we recruited 281 patients: 143 to chemotherapy and 138 to BSC. Histopathology was squamous in 269 (95.7%) patients. Median number of paclitaxel doses was 12 (IQR, 7-23). Median OS was 4.2 months (95% CI, 3.42-5.32) in BSC, and 9.2 months (95% CI, 8.02-10.48) in chemotherapy; HR, 0.49 (95% CI, 0.39-0.64); p < .001. As compared to BSC, chemotherapy increased response (2.9% to 39%), median PFS (2.1 to 4.2 months), 1-year OS (11% to 32%), 2-year OS (0 to 9%), median dysphagia-free survival (2.9 to 14.8 months), and global and esophagus-specific QoL, without significantly increasing all-grade or grade ≥3 toxicities. Using ESMO clinical benefit scale and ASCO Value Framework, palliative chemotherapy scored as having "substantial value." Our study provides the first level 1 evidence that chemotherapy prolongs survival in advanced esophageal/GEJ carcinoma. BSC alone is no longer appropriate. Weekly paclitaxel is an attractive option, especially in LMICs with limited access to immunotherapy.
RESUMO
PURPOSE: Our study investigated the impact of coronary artery calcification (CAC) and systemic inflammation on risks for major adverse cardiovascular events (MACE) following percutaneous coronary intervention (PCI). BACKGROUND: CAC and systemic inflammation are known to be associated with an increased risk of cardiovascular events. METHODS: A total of 17,711 consecutive patients who underwent PCI in our hospital between January 1, 2009 and December 31, 2015 were categorized according to the degree of CAC (moderate/severe vs. none/mild) and high-sensitivity C-reactive protein (hsCRP) level (≥2 vs. <2 mg/L). MACE was defined as death, myocardial infarction (MI), or target vessel revascularization (TVR) occurring over 1 year. RESULTS: Within the four groups, patients with both moderate/severe CAC and elevated hsCRP (n = 1,814 [10.2%]) were older with more comorbid risk factors compared to those with moderate/severe CAC alone (n = 1,687 [9.5%]), elevated hsCRP alone (n = 7,597 [42.9%]) or neither abnormality (n = 6,613 [37.3%]). The analogous 1-year MACE rates were 21.2, 14.9, 11.5, and 7.8%, respectively (p-trend < .001). Results were unchanged after multivariable adjustment, suggesting synergistic adverse effects in patients with both CAC and elevated hsCRP. CONCLUSIONS: The presence of both moderate/severe CAC and systemic inflammation confers a synergistic effect on risk for MACE following PCI, indicating the need for novel or more intense therapeutic interventions to mitigate risk in such patients.

BACKGROUND: There are limited data on the role of chemotherapy in patients with small cell lung cancer (SCLC) and poor performance status (PS). METHODS: This was a retrospective analysis of a prospective observational study in patients with SCLC and PS 3 or 4. We recorded the initial therapy, symptom improvement, response rate, overall survival (OS), and the impact of various factors on OS. RESULTS: From June 2010 to August 2019, we enrolled 234 patients; 185 (79%) with PS 3 and 49 (21%) PS 4. Initial therapy was best supportive care (BSC) in 49 patients (21%), standard full dose chemotherapy in 31 (13%), and attenuated chemotherapy in 154 (66%). In 89% patients treated with attenuated chemotherapy, symptom-relief occurred at a median of 3 days (IQR, 1-7). Grade 3 and higher toxicities developed in 60% patients treated with initial attenuated chemotherapy, commonly hyponatremia in 39%, neutropenia in 16%, anemia in 11%, and infection in 10%. Grade 3 and higher toxicities as a result of standard chemotherapy occurred in 89% patients treated with upfront standard full dose chemotherapy compared to 69% of patients who received initial attenuated chemotherapy with subsequent treatment escalation. Overall, there were 6 (2.6%) toxic deaths. The response rate to chemotherapy was 77%. The median OS of the patients who received any chemotherapy was significantly longer at 6 months (95% CI, 4.8-7.2) compared to 1 month (95% CI, 0.4-1.6 months) in patients who were managed with BSC, p < 0.001; hazard ratio, 0.39 (95% CI, 0.27-0.56). The disease stage, lactate dehydrogenase level, and receipt of chemotherapy significantly impacted survival. CONCLUSION: Chemotherapy prolongs survival in patients with SCLC and poor PS. Administering an initial attenuated chemotherapy regimen followed by standard full-dose chemotherapy when the PS improves may lower toxicity and improve tolerance.

Aims: It remains unknown what percentage of patients treated with percutaneous coronary artery intervention (PCI) have high residual inflammatory risk (RIR). Moreover, the impact of RIR on clinical outcomes has not been established. The objective of this study is to determine the prevalence of patients with persistent high levels of inflammation after PCI and to evaluate clinical outcomes according to inflammatory response. Methods and results: This is a retrospective cohort study assessing patients undergoing PCI between 2009 and 2016 with serial inflammatory status assessment from a large, prospective, and single-centre PCI registry. Assessment of inflammation status with at least two high sensitive C-reactive protein (hsCRP) measurements at baseline and follow-up with >4 weeks apart. High RIR was defined as an hsCRP≥ 2 mg/L. Patients were divided into four groups: persistent high RIR, increased RIR (first low-, then high hsCRP), attenuated RIR (first high-, then low hsCRP), or persistent low RIR. The primary endpoint was all-cause mortality at 1 year follow-up. Occurrence of myocardial infarction (MI) was assessed as secondary outcome. Seven thousand and twenty-six patients were identified with serial hsCRP measurements (30.8% of all PCI patients). Of these patients 2654 (38%) had persistent high RIR, 719 patients (10%) had increased RIR, 1088 patients (15%) had attenuated RIR, and persistent low RIR was seen in 2565 patients (37%). All-cause mortality at 1 year was 2.6% in patients with persistent high RIR, compared with 1.0% in increased RIR, 0.3% in attenuated RIR, and 0.7% in persistent low RIR patients, P < 0.01. MI at 1 year was observed in 7.5% of persistent high RIR, compared with 6.4% in increased RIR, 4.6% in attenuated RIR, and 4.3% in persistent low RIR, P < 0.01. In an adjusted model, including accounting for diabetes mellitus, acute coronary syndrome, and baseline low-density lipoprotein, results were sustained. Conclusion: Persistent high RIR is observed frequently in patients undergoing PCI. In these patients, significantly higher all-cause mortality and MI rates are observed at 1 year follow-up. Residual inflammatory risk in patients undergoing PCI should be identified and treatment options should be further explored.

PURPOSE: In the weekly-3-weekly study, cisplatin at 100 mg/m2 once-every-3-weeks led to superior locoregional control compared with cisplatin 30 mg/m2 once-a-week in combination with radical radiation for locally advanced head and neck squamous cell carcinoma (LAHNSCC). We report the updated analysis of the study. METHODS AND MATERIALS: In this phase 3 open-label noninferiority study conducted between 2013 and 2017, 300 patients with LAHNSCC were randomly assigned to receive cisplatin 100 mg/m2 once-in-every-weeks or cisplatin 30 mg/m2 once-a-week, concurrently with radiation. The primary endpoint was locoregional control. Secondary outcomes were overall survival, progression-free survival, and late adverse events. RESULTS: The median follow-up was 6.91 years (95% CI, 6.12-7.36). The updated 2-year and 5-year locoregional control rates for the once-a-week cisplatin arm were 58.75% (95% CI, 51.08-67.58) and 48.09% (95% CI, 40.26-57.43), whereas for the once-every-3-weeks, cisplatin arm were 73.95% (95% CI, 66.93-81.70) and 56.76% (95% CI, 48.46-66.48), respectively, hazard ratio = 1.44 (95% CI, 1.03-2.03), P = .034. The 5-year overall survival was 43.60% (95% CI, 36.29-52.37) in the once-a-week cisplatin arm and 50.55% (95% CI, 43.06-59.35) in the once-every-3-weeks cisplatin arm; P = .19. There was no difference in any grade or grade ≥3 late adverse events between the 2 arms, except for hearing dysfunction, which was significantly more common in patients who received high-dose cisplatin. CONCLUSIONS: Long-term follow-up confirms that cisplatin at 100 mg/m2 administered once-every-3-weeks concurrently with radical radiation for LAHNSCC leads to superior locoregional control compared with cisplatin 30 mg/m2 once-a-week and should remain one of the standard treatment options.
RESUMO
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.
RESUMO
PURPOSE: Standard neoadjuvant chemotherapy (NACT) for locally advanced esophageal/gastroesophageal junction squamous cancer (LAEGSC), 5-fluorouracil (5FU)+platinum, is toxic and logistically challenging; alternative regimens are needed. PATIENTS AND METHODS: Phase III randomized open-label non-inferiority trial at Tata Memorial Center, India, in resectable LAEGSC. Patients were randomized 1:1 to three cycles of 3-weekly platinum (cisplatin 75 mg/m2 or carboplatin AUC 6) with paclitaxel 175 mg/m2 (day 1) or 5FU 1000 mg/m2 continuous infusion (days 1-4), followed by surgery. RESULTS: Between August 2014 and June 2022, we enrolled 420 patients; 210 to each arm. Significantly more patients on paclitaxel + platinum (194 (92.3%)] received all 3 chemotherapy cycles than on 5FU+platinum (170 [85.9%]), P = .009. 5FU + platinum caused more grade ≥ 3 toxicities (124 [69.7%]) than paclitaxel + platinum (97 [51.9%]), P = .001. Surgery was performed in 131 (62.4%) patients on 5FU + platinum vs 139 (66.2%) on paclitaxel + platinum, P = .415. Paclitaxel + platinum resulted in higher pathologic primary tumor clearance (33 [25.8%]) vs 17 [15%]; P = .04), and pathologic complete responses in 21.9% compared to 12.4% from 5FU + platinum, P = .053. Median OS was 27.5 months (95% CI, 18.6-43.5) from paclitaxel + platinum, which was non-inferior to 27.1 months (95% CI, 18.8-40.7) from 5FU + platinum; HR, 0.89 (95% CI, 0.72-1.09); P = .346. CONCLUSION: Neoadjuvant paclitaxel + platinum chemotherapy is safer, and results in similar R0 resections, higher pathologic tumor clearance and non-inferior survival, compared to 5FU + platinum. Paclitaxel + platinum should replace 5FU + platinum as NACT for resectable LAEGSC. CLINICAL TRIALS REGISTRY INDIA NUMBER: CTRI/2014/04/004516.
RESUMO
The ocular system, unlike any other human body organ, is a system in which foreign bodies appear quite defenceless in front of the eye. Several infections of the ocular system occur due to various opportunistic conditions. Cytomegalovirus (CMV) is one of the opportunivores that causes several posterior eye infections. Ganciclovir (GCV),9-(2-hydroxy-1-(hydroxymethyl) ethoxymethyl), is aguanine-antiviral agent primarily used to treat CMV diseases. However, the major challenge is of lower bioavailability. Hence, GCV must be dosed repeatedly to enhance drug absorption. but this causes side effects like neutropenia and bone marrow suppression. So, formulators have used alternative formulation strategies such as prodrug formulation and colloidal drug delivery systems. In the prodrug strategy, they attempted to bind various compounds into the parent drug to increase the permeability and bioavailability of GCV. In colloidal drug delivery systems, mucoadhesive microspheres, nanoparticles, Niosome and liposome were employed to extend the drug residence time at the application site. This paper discusses several colloidal carriers combined with GCV to treat opportunistic CMV infection in the posterior ocular system. It reviews the limitations of conventional ocular therapy and explores various novel formulation approaches to improve the ocular bioavailability of GCV in the posterior chamber of the eye.
RESUMO
Osteoporosis is a bone incapacitating malady which globally accounts for over hundred million fractures annually. Therapeutic interventions for management of osteoporosis are divided as antiresorptive agents and osteoanabolic agents. Teriparatide is the only osteoana-bolic peptide which is available world-wide for the treatment of osteoporosis. It is administered as a daily subcutaneous injection for the treatment of osteoporosis which results in both poor patient compliance and increase in the cost of the therapy. Even after 20 years of clinical use of teriparatide, no formulation of teriparatide has yet been translated from lab to clinic which can be delivered by non-invasive route The present review critically discusses attempts made by the researchers for efficient delivery of teriparatide through various non-invasive routes such as oral, nasal, pulmonary, and transdermal route. It also discusses long-acting injectable formulations of teriparatide to improve patient compliance. Understanding on the pharmacology of teriparatide highlights the enhanced effectiveness of intermittent/pulsatile mode of teriparatide delivery which has also been elaborated. In addition, targeted delivery of teriparatide using different bone specific targeting moieties has been also discussed.
RESUMO
Pantoprazole decreases the acidity of the tumor microenvironment by inhibiting proton pumps on the cancer cell. This possibly leads to increased sensitivity to cytotoxic therapy. We conducted a phase I/II randomized controlled trial in adult patients with head and neck squamous cell carcinoma (HNSCC) planned for first-line palliative chemotherapy. Patients were randomized to chemotherapy + / - intravenous (IV) pantoprazole. The primary endpoint in phase I was to determine the maximum safe dose of intravenous pantoprazole, whereas it was progression-free survival (PFS) in phase II. The dose of IV pantoprazole established in phase I was 240 mg. Between Nov'18 and Oct'20, we recruited 120 patients in phase II, 59 on pantoprazole and 61 on the standard arm. Median age was 51 years (IQR 43-60), 80% were men. Systemic therapy was IV cisplatin in 22% and oral-metronomic-chemotherapy (OMC) in 78%. Addition of pantoprazole did not prolong PFS, which was 2.2 months (95% CI 2.07-3.19) in the pantoprazole arm and 2.5 months (95% CI 2.04-3.81, HR, 1.14; 95% CI 0.78-1.66; P = 0.48) in the standard arm. Response rates were similar; pantoprazole arm 8.5%, standard arm 6.6%; P = 0.175. Overall survival was also similar; 5.6 months (95% CI 4.47-8.51) in the pantoprazole arm and 5.4 months (95% CI 3.48-8.54, HR 1.06; 95% CI 0.72-1.57; P = 0.75) in the standard arm. Grade ≥ 3 toxicities were similar. Thus, pantoprazole 240 mg IV added to systemic therapy does not improve outcomes in patients with advanced HNSCC.

INTRODUCTION: Plasma cfDNA-based mutation analysis has shown disease-monitoring potential in various cancers. We assessed the potential of cfDNA-based EGFR mutation testing as a monitoring tool in patients with NSCLC. PATIENTS AND METHODS: Patients with NSCLC harboring EGFR mutations receiving first-line treatment as per institutional protocol were enrolled. EGFR mutation status was determined using plasma samples at baseline and post treatment initiation. Patients in whom EGFR mutation was detected or persisted after treatment initiation were considered circulating tumor DNA (ctDNA)-positive. Progression-free survival (PFS) and overall survival (OS) for ctDNA-positive and negative patients post treatment initiation were the primary endpoints; concordance for baseline EGFR status between tissue and plasma and proportion of patients who were ctDNA-positive post treatment initiation were the secondary endpoints. RESULTS: We enrolled 158 patients; 76 received gefitinib, and 82 received gefitinib plus chemotherapy. Median follow-up duration was 42 months. About 25% of patients were ctDNA-positive post treatment initiation. Median PFS for ctDNA-negative patients post treatment initiation was 14 (95% confidence interval [CI], 12.0-17.0) months, while that for ctDNA-positive patients was 8 (95% CI, 6.0-10.0) months. Median OS for ctDNA-negative patients post treatment initiation was 27 (95% CI, 24.0-32.0) months, while that for ctDNA-positive patients was 15 (95% CI, 11.0-19.0) months. Concordance at baseline between tissue and plasma samples was 75.4%. CONCLUSION: Plasma-based EGFR mutation detection post treatment initiation can be used as a predictive marker for outcome in patients with EGFR-mutant NSCLC receiving first-line treatment.

BACKGROUND: A significant proportion of non-small cell lung cancer (NSCLC) patients present with poor performance status (PS) at baseline are almost always excluded from the clinical trials leading to availability of only limited data in this subgroup. PATIENTS AND METHODS: This was an observational single institutional study. The eligibility criteria for inclusion were a histologic or cytologic diagnosis of advanced NSCLC and Eastern Cooperative Oncology Group PS 3 or 4. All patients coming between June 2015 and December 2018 were evaluated for inclusion in this study. RESULTS: A total of 245 patients were enrolled in the study. The median age of the patients was 63 years (range 25-89), 142 (58%) were male, 196 (80%) had adenocarcinoma histology and 192 (78.4%) has PS 3 while rest (21.6%) had PS 4. Out of 245 patients, 192 (78.4%) received oral tyrosine kinase inhibitors (TKI) and supportive care, 45 (18.4%) received supportive care alone, while 8 (3.2%) patients received chemotherapy along with supportive care. Median overall survival (OS) was 3 months (95% CI: 1.8-4.2) in patients who received oral TKI versus 1 month (1.0-2.9) in patients who received supportive care alone (log-rank p = 0.013). The median OS for epidermal growth factor receptor (EGFR) mutant patients who received oral TKI was 12 months (95% CI: 7.7-16.3), while it was 3 months (95% CI: 1.5-4.5) for patients who were EGFR wild-type and received TKI on compassionate basis (HR = 0.50; 95% CI: 0.32-0.77; p = 0.001). CONCLUSIONS: The use of oral TKI on a compassionate basis led to improvement in survival in the overall cohort of the patients; this was principally driven by EGFR-mutated patients.
RESUMO
BACKGROUND: Although cough is a common and distressing symptom in patients with lung cancer, there is almost no evidence to guide treatment. Aprepitant, a centrally acting neurokinin-1 inhibitor, significantly decreased cough frequency in a pilot study. METHODS: Patients with advanced lung cancer and cough lasting over 2 weeks despite a cough suppressant were randomized 1:1 to aprepitant 125 mg orally on day 1 and then 80 mg orally on days 2 to 7 with physician's choice of antitussive; or to physician's choice of antitussive alone. Evaluation was at baseline and on days 3, 7, 9, and 12. The primary end point was subjective cough improvement on day 9, measured by the Visual Analog Scale and Manchester Cough in Lung Cancer Scale. Secondary end points included quality of life (QoL) as measured by the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire and the EORTC Lung Cancer-Specific Quality of Life Questionnaire and toxicity. RESULTS: Between 2017 and 2018, 128 patients were randomized. Median baseline cough duration was 90 days. Mean Visual Analog Scale scores (in mm) at baseline and day 9 were 68 and 39 in the aprepitant arm and 62 and 49 in the control arm, respectively (P < .001); mean Manchester Cough in Lung Cancer Scale scores at baseline and day 9 were 33 and 23 in the aprepitant arm and 30 and 25 in the control arm, respectively (P < .001). Overall QoL was not significantly different between the two arms; however, aprepitant led to a significant improvement in the cough-specific QoL domain (P = .017). Aprepitant did not increase severe adverse events. CONCLUSIONS: Aprepitant led to a significant improvement in cough in advanced lung cancer, without increasing severe side effects.

PURPOSE: Standard first-line therapy for EGFR-mutant advanced non-small-cell lung cancer (NSCLC) is an epidermal growth factor receptor (EGFR)-directed oral tyrosine kinase inhibitor. Adding pemetrexed and carboplatin chemotherapy to an oral tyrosine kinase inhibitor may improve outcomes. PATIENTS AND METHODS: This was a phase III randomized trial in patients with advanced NSCLC harboring an EGFR-sensitizing mutation and a performance status of 0 to 2 who were planned to receive first-line palliative therapy. Random assignment was 1:1 to gefitinib 250 mg orally per day (Gef) or gefitinib 250 mg orally per day plus pemetrexed 500 mg/m2 and carboplatin area under curve 5 intravenously every 3 weeks for four cycles, followed by maintenance pemetrexed (gefitinib plus chemotherapy [Gef+C]). The primary end point was progression-free survival (PFS); secondary end points included overall survival (OS), response rate, and toxicity. RESULTS: Between 2016 and 2018, 350 patients were randomly assigned to Gef (n = 176) and Gef+C (n = 174). Twenty-one percent of patients had a performance status of 2, and 18% of patients had brain metastases. Median follow-up time was 17 months (range, 7 to 30 months). Radiologic response rates were 75% and 63% in the Gef+C and Gef arms, respectively (P = .01). Estimated median PFS was significantly longer with Gef+C than Gef (16 months [95% CI, 13.5 to 18.5 months] v 8 months [95% CI, 7.0 to 9.0 months], respectively; hazard ratio for disease progression or death, 0.51 [95% CI, 0.39 to 0.66]; P < .001). Estimated median OS was significantly longer with Gef+C than Gef (not reached v 17 months [95% CI, 13.5 to 20.5 months]; hazard ratio for death, 0.45 [95% CI, 0.31 to 0.65]; P < .001). Clinically relevant grade 3 or greater toxicities occurred in 51% and 25% of patients in the Gef+C and Gef arms, respectively (P < .001). CONCLUSION: Adding pemetrexed and carboplatin chemotherapy to gefitinib significantly prolonged PFS and OS but increased toxicity in patients with NSCLC.

Studies have shown worse outcome for women compared with men after percutaneous coronary intervention (PCI), especially in the presence of diabetes mellitus (DM). We aimed to investigate the risk of ischemic events after PCI in women versus men stratified by the presence or absence of DM. A total of 17,154 consecutive patients from a single-center PCI registry enrolled from January 2009 to December 2014 were categorized accordingly: female/non-DM, female/DM, male/non-DM, and male/DM. End points included death and myocardial infarction (MI) at 1 year. Of the overall population, 15% (n = 2,631) were female/non-DM, 17% (n = 2,891) were female/DM, 38% (n = 6,483) were male/non-DM, and 30% (n = 5,149) were male/DM. Within the 4 study groups, female/DM had the highest risk, whereas female/non-DM and male/DM showed similar risks and male/non-DM showed lowest risk for death (4.64% vs 3.08% vs 2.93% vs 2.31%; p-trend <0.0001 over all groups and p = 0.69 between female/non-DM and male/DM, respectively) and MI (4.15% vs 3.99% vs 3.71% vs 2.55%; p trend <0.0001 over all groups and p = 0.97 between female/non-DM and male/DM, respectively). After multivariate adjustment findings were largely unchanged suggesting highest risk for adverse events in diabetic women compared with other groups and comparable risks for death and MI in nondiabetic women compared with diabetic men. In conclusion, these findings highlight the combined influence of DM and female gender as strong determinants of post-PCI risk while also illustrating "risk equivalence" between nondiabetic women versus diabetic men.

There are little data on the efficacy and safety of taxane/platinum with definitive radiotherapy (RT) for esophageal/GEJ cancer. This article is a retrospective analysis of patients who received weekly paclitaxel 50 mg/m(2) and carboplatin AUC 2 with radical definitive RT for locally advanced esophageal/GEJ cancer. Between February 2011 and July 2014, 179 patients were included. The median age was 54 years. Ninety-two percent of patients had squamous histology. Mean RT dose was 58.7 Gy in 32 fractions over 53 days, with mean of six chemotherapy cycles. Fifty-six percent of patients developed ≥grade 3 acute toxicities, commonly febrile neutropenia (12%) and infection (11%); ≥grade 3 laboratory abnormalities included hyponatremia (38%), leukopenia (49%), neutropenia (27%), and anemia (16%). Twelve percent of patients developed ≥grade 3 chronic toxicity. Fatal toxicities included six during CRT, eight within 30 days of completing CRT, and three chronic. Radiologic response was 49% (CR 5.6%, PR 43%). Follow-up endoscopy showed remission in 53% and residual disease in 14%. At a median follow-up of 28 months, median PFS was 11 months (95% CI: 8-13.9), median OS was 19 months (95% CI: 15.4-22.6), and estimated 1-year, 2-year, and 3-year survivals were 70%, 47%, and 39%, respectively. Weekly paclitaxel-carboplatin concurrently with definitive RT is efficacious with manageable toxicity. [The trial was registered with the Clinical Trials Registry-India (CTRI), registration number: CTRI/2014/07/004776.].
