Mebendazole plus lomustine or temozolomide in patients with recurrent glioblastoma: A randomised open-label phase II trial.

Background: Recurrent glioblastoma (GBM) has dismal outcomes and limited treatment options. Mebendazole (MBZ) has activity in glioma both in-vivo and in-vitro, and is well tolerated in combination with lomustine (CCNU) and temozolomide (TMZ). In this study, we sought to determine whether the addition of MBZ to CCNU or TMZ would improve overall survival (OS) in recurrent GBM. Methods: In this phase II randomized open-label trial, adult patients with ECOG PS 0-3, with recurrent GBM who were not eligible for re-radiation, were randomized 1:1 to the CCNU-MBZ and TMZ-MBZ arms. CCNU was administered at 110 mg/m2 every 6 weeks with MBZ 800 mg thrice daily and TMZ was administered at 200 mg/m2 once daily on days 1-5 of a 28 days cycle with MBZ 1600 mg thrice daily. The primary endpoint was OS at 9 months. A 9-month OS of 55% or more in any arm was hypothesized to warrant further evaluation and a value below 35% was too low to warrant further investigation. OS was analyzed using intention to treat (ITT) and per-protocol (PP) analyses. Per-protocol analysis was used for safety analysis. Clinical Trials Registry-India number, CTRI/2018/01/011542. Findings: Participants were recruited from 14th March 2019 to 18th June 2021, 44 patients were randomised on each arm. At 17.4 months, 68 events for OS analysis had occurred, 33 in the TMZ-MBZ and 35 in the CCNU-MBZ arm. The 9-month OS was 36.6% (95% CI 22.3-51.0) and 45% (95% CI 29.6-59.2) in the TMZ-MBZ and CCNU-MBZ arms respectively, in the ITT population. ECOG PS was the only independent prognostic factor impacting OS (HR-0.48, 95% CI 0.27-0.85; P = 0.012). Grade 3-5 adverse events were seen in 8 (18.6%; n = 43) and 4 (9.5%; n = 42) patients in the TMZ-MBZ and CCNU-MBZ arms respectively. There were no treatment related deaths. Interpretation: The addition of MBZ to TMZ or CCNU failed to achieve the pre-set benchmark of 55% 9-month OS. This was probably due to 28.6% of patients having poor PS of 2-3. Funding: Brain Tumor Foundation (BTF) of India, Indian Cooperative Oncology Network (ICON), and India Cancer Research Consortium (ICRC) under ICMR (Indian Council of Medical Research).

Effect of Mindfulness-Based Art Therapy (MBAT) on Psychological Distress and Spiritual Wellbeing in Breast Cancer Patients Undergoing Chemotherapy.

OBJECTIVES: Psychological distress and spiritual well-being (SWB) are directly related to the quality of life in cancer patients. Mindfulness-Based Art Therapy (MBAT) integrates mindfulness practices with art therapy and has shown to decrease distress levels and improve SWB in women with breast cancer. The objective of the study was to identify the effects of a 1-week MBAT intervention on psychological distress and SWB in breast cancer patients undergoing chemotherapy. MATERIALS AND METHODS: This was a single group, pre-test post-test study carried out in a clinical setting. The psycho-oncology assessment questionnaire, Distress Thermometer (DT) and Functional Assessment of Chronic Illness Therapy-SWB Scale 12 (FACIT-SP12) Version 4 were administered before, post1st supervised MBAT session and post 1 week of home practice to breast cancer patients undergoing chemotherapy (n = 30). The MBAT intervention included mindfulness meditation for 15 min and mindful coloring for 30 min daily for 1 week. Data analysis was done using R i386 4.0.3. RESULTS: The median DT score significantly decreased from pre-session to immediate post-session and pre-session to post 1-week session. The median of meaning, peace, and faith subscales of FACIT SP12 scores along with total FACIT SP12 score significantly increased from pre-session to immediate post-session as well as from pre-session to post 1 week. CONCLUSION: One-week MBAT intervention for breast cancer patients undergoing chemotherapy significantly decreased the psychological distress and significantly improved the SWB in terms of meaning, peace, and faith.

Third-line therapy in the epidermal growth factor receptor mutation-positive advanced nonsmall-cell lung cancer.

INTRODUCTION: The treatment of lung cancer is not defined in the third-line setting and remains an unanswered question. Erlotinib is the only drug approved in the third-line setting. With the introduction of effective first- and second-line therapies, more and more patients warrant an effective third-line therapy. We did a post hoc analysis of our randomized trial for the epidermal growth factor receptor (EGFR)-positive patients who received third-line therapy. MATERIALS AND METHODS: The present series is of 85 patients who received third-line therapy. Demographic data were collected which included age, performance status, gender, stage, comorbidities, and sites of metastasis. Data were collected for the type of systemic treatment patients received and number of cycles received. Information related to the impact of treatment on the symptoms of patients and the imaging done for response evaluation was collected. RESULTS: Of the 85 patients, there were 13 patients (15%) who achieved a partial response and 34 patients (40%) who had stable disease as best response. There were no complete response and 20 patients (24%) had disease progression at the time of first assessment. The median overall survival (OS) was 8.36 months (95% confidence interval [CI] 6.8-9.8 months) and median progression-free survival was 4.4 months (95% CI 3.3-4.9 months). Grade 3 or 4 toxicities were seen in 42.5% (n = 36) of the total patients. CONCLUSIONS: The study provides the patterns and outcomes of systemic treatment in metastatic EGFR-mutated lung adenocarcinoma in patients who have progressed on two or more lines of systemic therapies. This data suggest that third-line systemic therapy may provide meaningful outcomes in these patients.

Randomized phase 3 open label study of quality of life of patients on Pemetrexed versus Erlotinib as maintenance therapy for advanced non squamous non EGFR mutated non small cell lung cancer.

Background: We planned to compare pemetrexed maintenance with erlotinib maintenance in non squamous non Epidermal Growth Factor Receptor (EGFR) mutated non small cell lung cancer (NSCLC). The null hypothesis for this study was that there would be no difference in quality of life (QOL) between pemetrexed and erlotinib maintenance. Results: The QL2 scores at 3 months were 63.35 (SD 24.99) in pemetrexed arm and 63.01(SD 23.04) in erlotinib arm (p-0.793). Except in 1 domain, the scores were statistically similar between the 2 arms. In the domain of diarrhea, the score was higher as expected in the erlotinib arm (p-0.048). The median progression free survival was 4.5 months (95%CI 4.1-4.9 months) in pemetrexed arm versus 4.5 months (95%CI 3.8-5.2 months) in erlotinib arm (p-0.94). The median overall survival was 16.6 months (15.2-17.9 months) in pemetrexed arm versus 18.3 months (95% CI 13.75-22.91 months) in erlotinib arm (p-0.49). Methods: The study was an open label, single centre, parallel, phase 3 randomized study with 1:1 randomization between maintenance pemetrexed arm and erlotinib arm. Adult patients (age > or = 18 years), with non squamous EGFR mutation, treated with first line palliative therapy, with non progressive disease post 4-6 cycles of pemetrexed-carboplatin were randomized. Primary outcome was change in the score of QOL (Global health status {QL2}) at 3 months. We estimated that with 200 patients, the study had 80% power to detect a significant difference between the two groups in the change in the global health status score at 3 months with an alpha error of 5%, with an effect size of 0.3 SD. Conclusions: Maintenance pemetrexed post pemetrexed-platinum chemotherapy fails to improve QOL or time to event outcomes over maintenance erlotinib in EGFR mutation negative NSCLC.

A cross-sectional audit of distress in patients undergoing adjuvant therapy or follow-up in central nervous system malignancies.

BACKGROUND: Unaddressed high distress leads to noncompliance with treatment, negatively affects quality of life, and may also have a negative impact on the prognosis of cancer patients. Patients with brain tumors have higher levels of distress than the general population and hence we hypothesize that even routine visits during adjuvant treatment or follow-up are likely to be stressful. This analysis was performed to identify the incidence of distress and factors affecting it. METHODS: This was an audit of 84 consecutive patients seen in an adult neuro-medical oncology outpatient department who were either receiving adjuvant chemotherapy or were on follow-up. Distress screening with the National Comprehensive Cancer Network (NCCN) distress thermometer was performed. Patients in whom distress was scored as 4 or above were considered as having high distress. Descriptive statistics and logistic regression analysis were performed to identify factors affecting distress. RESULTS: The median age of the cohort was 40 years (interquartile range, 28.3 to 50 years). Actionable distress defined as a distress score of 4 or more was seen in 52 patients (61.9%, 95% CI 51.2% to 71.5%). Presence of physical deficit (odds ratio [OR] = 3.412, P = .020) and treatment under the private category (OR = 5.273, P = .003) had higher odds of having high distress. CONCLUSION: A high proportion of brain tumor patients either on adjuvant chemotherapy or on follow-up have high distress levels that need to be addressed even during follow-up.

A randomized phase 3 trial comparing nimotuzumab plus cisplatin chemoradiotherapy versus cisplatin chemoradiotherapy alone in locally advanced head and neck cancer.

BACKGROUND: Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. METHODS: This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. RESULTS: In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). CONCLUSIONS: The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

ROS1 mutation non-small cell lung cancer-access to optimal treatment and outcomes.

INTRODUCTION: ROS1 oncogenic fusion, which was first identified by Rikova et al, is reported to be present in 1%-2% of non-small cell lung cancers (NSCLCs) and is defined as a distinct molecular sub-group. Crizotinib is very effective in ROS1-positive patients and is now Food and Drug Administration (FDA) approved for the treatment of patients with advanced ROS1-positive NSCLC. We report our experience in a tertiary cancer care hospital in India in ROS-1 positive patients. MATERIALS AND METHOD: The present series is a retrospective analysis of 22 patients from the prospectively maintained lung cancer audit. Demographic data were collected which included age, performance status, gender, stage, co-morbidities, sites of metastasis and smoking history. Data were also collected regarding the source of financing for crizotinib whether self-financed, through insurance or Non-Governmental Organisation (NGO) sponsored. Patients who had tested negative for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) and were subsequently found to be ROS1-mutation negative by fluorescence in situ hybridization (FISH) were evaluated on similar lines. All the data were entered and statistical analyses were performed using the SPSS software version 22.0. Response evaluation was done by RECIST 1.1 criteria. RESULTS: Between January 2015 and December 2017, there were 22 patients who were ROS1 positive from a total of 535 patients in whom ROS1 testing was performed. A total of 16 patients could receive crizotinib and 6 patients were never exposed to crizotinib. Among the 16 patients who received crizotinib, 2 (12.5%) achieved complete response (CR) as their best response and continue to remain in CR at follow-up. 13 (81%) had a partial response as best response and of which on follow-up 5 (38%) have progressed, while 8 (62%) continue to maintain response. The patients who were on crizotinib had good tolerance with none experiencing any grade 3/4 toxicity. The median follow-up of the entire cohort was 15.2 months in ROS1-positive cohort and 11.4 months in ROS1-negative cohort. In ROS1-positive cohort median, progression-free survival (PFS) was not reached and the estimated 2-year PFS was 54% and in ROS1-negative cohort, it was 5.1 months. The median overall survival of the entire ROS1-positive cohort was not reached and the estimated 1- and 2-year overall survival (OS) was 72% and 54%, respectively, and was 8.8 months in ROS1-negative cohort. CONCLUSION: ROS1 rearrangement with an incidence of 4% of lung adenocarcinoma which is EGFR and ALK negative represents an important targetable driver mutation in the Indian population. Crizotinib also represents an effective treatment option with outcomes similar to those reported. Access to treatment remains an important roadblock to improve outcomes but innovative methods may improve access to these drugs.

Low prevalence of deficient mismatch repair (dMMR) protein in locally advanced rectal cancers (LARC) and treatment outcomes.

BACKGROUND: The available evidence in locally advanced rectal cancer (LARC) suggests a low prevalence of deficient mismatch repair (dMMR) protein status, approximating 1-3%. METHODS: Patients with LARC who were offered long course chemoradiation (LCRT), as per institution protocol during the period of 1st January 2014 to 31st December 2015 at Tata Memorial Hospital (TMH) in Mumbai were evaluated for outcomes and assessment of MMR status. RESULTS: A total of 419 patients were evaluated for LARC in TMH, of whom 354 were treated with LCRT. Of these 354 patients, 296 were assessable for MMR status based on tissue adequacy for testing. Three patients (1.01%) has dMMR status, while the remaining 293 patients had proficient MMR status. A total of 240 patients (67.8%) underwent curative intent resections. With a median follow-up of 32 months, estimated 3-year recurrence free survival (RFS) and overall survival (OS) for the resected group was 63.5% and 85.2%, respectively, while 3-year event free survival and OS for the unresected cohort was 15.2% and 15.8%, respectively. Signet ring histology, higher ypT stage, involved margin status post resection, and delays (>1 week) in LCRT were associated with inferior OS on multivariate analysis. CONCLUSIONS: In a large LARC cohort, a majority of tumors had proficient MMR status, suggesting that MSI as a biomarker may have limited applicability in the management of rectal cancers. Signet ring histology, CRM involvement post resection, higher ypT stage and interruptions in LCRT predicted for inferior OS.

Practice patterns and outcomes with the use of regorafenib in metastatic colorectal cancer: Results from the Regorafenib in Metastatic colorectal cancer - An Indian exploratory analysis study.

BACKGROUND: Regorafenib is considered a standard of care as third-line therapy in metastatic colorectal cancers (mCRCs). MATERIALS AND METHODS: The study was based on a computerized clinical data form sent to oncologists across the country for entry of anonymized patient data. The data entry form was conceived and generated by the coordinating center's (Tata Memorial Hospital) gastrointestinal medical oncologists and disseminated through personal contacts at academic conferences as well as through E-mail to various oncologists across India. RESULTS: A total of 19 physicians contributed data resulting in 80 patients receiving regorafenib who were available for the evaluation of practice patterns. The median age was 55 years (range: 24-75). Majority had received oxaliplatin-based (97.5%), irinotecan-based (87.5%), and targeted therapy (65%), previously. Patients were primarily started on reduced doses of regorafenib upfront (160 mg - 28.8%, 120 mg - 58.8%, and 80 mg - 12.5%). The median duration of treatment (treatment duration) with regorafenib was 3.1 months (range: 0.5-18), while the median progression free survival was 3.48 months (range: 2.6-4.3). Forty-five percent of patients required dose modifications due to toxicities, and the most common were (all grades) hand-foot syndrome (68.8%), fatigue (46.3%), mucositis (37.6%), and diarrhea (31.3%). CONCLUSIONS: Majority of physicians in this collaborative study from India used a lower dose of regorafenib at the outset in patients with mCRC. Despite a lower dose, there was a significant requirement for dose reduction. Duration of treatment with regorafenib as an efficacy end point in this study is similar to available data from other regions as it is the side effect profile.

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.

Resection of Isolated Port Site Metastasis in Gall Bladder Cancers-Careful Selection and Perioperative Systemic Therapy May Improve Outcomes.

Excision of port site (PSE) for patients having undergone laparoscopic cholecystectomy (LC) is not a standard recommendation. We retrospectively evaluated a cohort of patients with isolated PSM without any prior cancer-directed therapy who were assessed for resection between March 2012 and July 2016 at Tata Memorial Hospital, Mumbai. Eleven of a total 13 patients underwent wide excision for PSM in the given time period. Upfront resection was undertaken in six patients while seven patients received neoadjuvant chemotherapy (NACT) and two received neoadjuvant chemo radiotherapy (NACTRT) prior to attempted resection. With the median follow-up of 22 months, post PSM disease-free survival (DFS) was 20 months (95% CI 15-24 months) and overall survival (OS) was 37 months (95% CI 22-51 months). Careful selection along with an aggressive management strategy may be a step forward in the treatment of patients with isolated PSM.

Distress Management in Patients With Head and Neck Cancer Before Start of Palliative Chemotherapy: A Practical Approach.

PURPOSE: This study reports the incidence of distress, the factors associated with distress, and a practical strategy to resolve distress in patients with head and neck cancer who are starting palliative chemotherapy. METHODS: Adult patients with head and neck cancer planned for palliative chemotherapy underwent distress screening before the start of treatment as part of this single-arm prospective study. Patients who had a distress score > 3 on the National Comprehensive Cancer Network (NCCN) distress thermometer were counseled initially by the clinician. Those who continued to have high distress after the clinician-led counseling were referred to a clinical psychologist and were started on palliative chemotherapy. After counseling, distress was measured again. The relation between baseline distress and compliance was tested using Fisher's exact test. RESULTS: Two hundred patients were enrolled, and the number of patients with high distress was 89 (44.5% [95% CI, 37.8% to 51.4%]). The number of patients who had a decrease in distress after clinician-led counseling (n = 88) was 52 (59.1% [95% CI, 48.6% to 68.8%]) and after psychologist-led counseling (n = 32) was 24 (75.0% [95% CI, 57.6% to 72.2%]; P = .136). Compliance rates did not differ between the patients with or without a high level of distress at baseline (74.2% v 77.4%, P = .620). CONCLUSION: The incidence of baseline distress is high in patients awaiting the start of palliative chemotherapy. It can be resolved in a substantial number of patients using the strategy of clinician-led counseling, with additional referral to a clinical psychologist as required. Patients with a greater number of emotional problems usually require psychologist-led counseling.

Radiation-Induced Neuropsychiatric Manifestations in a Patient with Brain Metastasis: A Diagnostic and Therapeutic Challenges for Consultation-Liaison Psychiatrist.

The aim of this case report is to highlight diagnostic and therapeutic challenges for consultation-liaison psychiatrist in the case of radiation-induced neuropsychiatric syndrome. We report the case of a 61-year-old man presented with neurological and psychiatric manifestations following the radiation therapy for non-small cell lung carcinoma with brain metastasis. We have briefly reviewed and discussed the risk factors, clinical features, diagnostic, therapeutic, and preventive aspect of radiation-induced neuropsychiatric manifestations.

Shadow study: randomized comparison of clinic with video follow-up in glioma undergoing adjuvant temozolomide therapy.

AIM: This study was designed with a primary objective to study the rate of agreement in treatment plan and decisions between video follow-up (VF) and conventional clinic follow-up (CF). PATIENTS & METHODS: Adult patients with intermediate- to high-grade glioma on adjuvant temozolomide (TMZ) with facilities for live video call were invited to participate in the study. RESULTS: The concurrence in decision of administering TMZ between VF and CF was 100% (p < 0.00). The median cost incurred in VF was US$58.15 while that incurred in CF was US$131.23 (p < 0.00). CONCLUSION: VF can substitute CF during adjuvant TMZ administration (CTRI/2017/01/007626).

Efficacy of gefitinib in epidermal growth factor receptor-activating mutation-positive nonsmall cell lung cancer: Does exon 19 deletion differ from exon 21 mutation?

BACKGROUND: This study was designed to evaluate the differential effect of epidermal growth factor receptor (EGFR) mutation status (exon 19 vs. 21) on progression-free survival (PFS) and overall survival (OS) in treatment-naïve advanced EGFR mutation-positive nonsmall cell lung cancer (NSCLC) treated with gefitinib as first-line agent. METHODS: This was a post hoc analysis of EGFR-mutated (exon 19 and 21) advanced-stage (Stage IIIB or IV), chemotherapy-naive NSCLC patients treated with gefitinib as first line in a phase 3 randomized study. Patients were treated with gefitinib 250 mg daily. Patients underwent axial imaging for response assessment on D42, D84, D126, and subsequently every 2 months till progression. Responding or stable patients were treated until progression or unacceptable toxicity. SPSS was used for statistical analysis. Kaplan-Meier method was used for survival estimation and log-rank test for comparison. Cox proportion hazard model was used for multivariate analysis. RESULTS: One hundred and forty-one patients were eligible for analysis, of which 78 were males and 63 were females. A total of 127 patients (90.1%) were ECOG 0-1 while 14 patients (9.1%) were ECOG >1. Exon 21 mutation was present in 65 patients (46.1%) and exon 19 mutation in 76 patients (53.9%). One hundred and thirty-three of 141 patients were evaluable for response. Response rate of patients having exon 19 mutation was 72.9% (51 patients, n = 70) while it was 55.6% in patients having exon 21 mutation (35 patients, n = 63) (P = 0.046). Median PFS in exon 19-mutated patients was 9.3 months (95% confidence interval [CI] 6.832-11.768) compared to 7.8 months (95% CI 5.543-10.0) (P = 0.699) in exon 21-mutated patients. The median OS in exon 19-mutated patients was 19.8 months (95% CI 16.8-22.7), and it was 16.5 months (95% CI 10.9-22.1) in exon 21-mutated patients (P = 0.215). CONCLUSION: There were no differential outcomes in the Indian patients of advanced-stage NSCLC with exon 19 and 21 EGFR mutations treated with gefitinib.

Once-a-Week Versus Once-Every-3-Weeks Cisplatin Chemoradiation for Locally Advanced Head and Neck Cancer: A Phase III Randomized Noninferiority Trial.

Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m2 resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m2, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Efficacy of Second-Line Pemetrexed-Carboplatin in EGFR-Activating Mutation-Positive NSCLC: Does Exon 19 Deletion Differ from Exon 21 Mutation?

BACKGROUND: It is unknown whether the outcomes of second-line pemetrexed-carboplatin chemotherapy administered after progression on gefitinib are dependent on type of EGFR mutation present at baseline. METHOD: Adult non-small-cell lung cancer patients, with exon 19 deletion or exon 21 L858R mutation, who progressed on gefitinib and received pemetrexed-carboplatin chemotherapy were selected for this analysis. RESULT: 55 patients received pemetrexed-carboplatin as second-line treatment. Response rates in evaluable patients were 39.3% in exon 19 patients (n = 28) and 33.3% in exon 21 patients (n = 15) (p = 0.752, Fisher's exact 2-sided p value). The median PFS in exon 19 and 21 cohorts was 5.900 months (95% CI: 4.274-7.526) and 4.767 months (95% CI: 1.374-8.159), respectively. The median overall survival in exon 19 patients was (11.8 months, 95% CI: 9.916-13.684 months) significantly better than that seen in exon 21 mutation patients (6.2 months, 95% CI: 4.215-8.118 months, p = 0.024) on univariate analysis; however, on multivariate analysis, this association was not confirmed (HR = 0.361, 95% CI: 0.090-1.439, p = 0.149). CONCLUSION: Exon 19 deletion has no impact on PFS and OS in EGFR-mutated patients treated with second-line pemetrexed-carboplatin.

Results of a phase II randomized controlled clinical trial comparing efficacy of Cabazitaxel versus Docetaxel as second line or above therapy in recurrent head and neck cancer.

BACKGROUND: Cabazitaxel has shown activity in squamous cancer cell lines and in taxane resistant cell lines. Hence we planned a phase 2 study to evaluate the efficacy of cabazitaxel against Docetaxel in recurrent head and neck cancer, post first line treatment. METHODS: This was a phase 2, investigator initiated, randomized controlled trial of Docetaxel (75 mg/m2) versus Cabazitaxel (20 mg/m2), in patients with head and neck cancer with ECOG performance status 0-2 who have been exposed to at least one line of chemotherapy, involving a sample size of 92 (46 per group)(CTRI/2015/06/005848). Disease control rate at 6 weeks was assessed and compared using the chi-square test. RESULTS: The disease control rate at 6 weeks was better in the Docetaxel arm over the cabazitaxel arm (52.3% versus 13.6%, p = 0.017). The median progression free survival was 21 days (95% CI 5.28 to 36.72 days) in the cabazitaxel arm versus 61 days (95% CI 21.39 to 100.60 days) in the Docetaxel arm (HR-1.455, 95% CI 0.919-2.304, p = 0.100). The median overall survival was 115 days (95% CI 74.04 to 155.95 days) in the cabazitaxel arm versus 155 days (95% CI 148.6 to 161.40 days) in the Docetaxel arm (HR-1.464, 95% CI 0.849-2.523, p = 0.170). CONCLUSION: Docetaxel had a superior disease control rate at 6 weeks compared to cabazitaxel.
